Use of the hCONSORT Criteria as a Reporting Standard for Herbal Interventions for Common Dermatoses - A Systematic Review

Abstract

Background

The use of complementary and alternative medicine (CAM) is increasing in western countries, including in the area of dermatology. However, western healthcare providers have not integrated CAM into regular practice due to a lack of reliable data supporting its use. In order to encourage high quality research related to the use of CAM and specifically herbal interventions, the CONSORT extension criteria on reporting herbal interventions (hCONSORT) were published in 2006.

Objectives

This study aimed to evaluate the adherence of randomized controlled trials investigating herbal interventions for 3 common dermatoses (acne, atopic dermatitis, and psoriasis) to the hCONSORT criteria.

Methods

A comprehensive search of Medline, Embase, and Cochrane library databases was conducted. Randomized control trials published between 2009 and 2014 assessing therapeutic outcomes of plant-based interventions for acne, atopic dermatitis, or psoriasis were included. Investigators determined the number of unique hCONSORT criteria satisfied per report. Analysis of variance was used to examine differences in scores by disease entity.

Results

The vast majority of reviewed studies reported less than 50% of information recommended in the hCONSORT criteria.

Limitations

Limitations include small number of dermatologic conditions examined, exclusion of reports based on language, and lack of assessment of overall adherence to CONSORT criteria

Conclusions

Our data indicates lack of adherence to hCONSORT extension criteria. Adherence to hCONSORT guidelines should be encouraged in order to provide high quality reporting of research on herbal interventions in dermatology. Doing so may ease the integration of CAM into conventional medical practice and provide actionable data to providers.

AimRed and processed meat may be risk factors for breast cancer due to their iron content, administration of oestrogens to cattle or mutagens created during cooking. We studied the associations in UK Biobank and then included the results in a meta-analysis of published cohort studies.MethodsUK Biobank, a general population cohort study, recruited participants aged 40–69 years. Incident breast cancer was ascertained via linkage to routine hospital admission, cancer registry and death certificate data. Univariate and multivariable Cox proportional hazard models were used to explore the associations between red and processed meat consumption and breast cancer. Previously published cohort studies were identified from a systematic review using PubMed and Ovid and a meta-analysis conducted using a random effects model.ResultsOver a median of 7 years follow-up, 4819 of the 262,195 women developed breast cancer. The risk was increased in the highest tertile (>9 g/day) of processed meat consumption (adjusted hazard ratio [HR] 1.21, 95% confidence interval [CI] 1.08–1.35, p = 0.001). Collation with 10 previous cohort studies provided data on 40,257 incident breast cancers in 1.65 million women. On meta-analysis, processed meat consumption was associated with overall (relative risk [RR] 1.06, 95% CI 1.01–1.11) and post-menopausal (RR 1.09, 95% CI 1.03–1.15), but not pre-menopausal (RR 0.99, 95% CI 0.88–1.10), breast cancer. In UK Biobank and the meta-analysis, red meat consumption was not associated with breast cancer (adjusted HR 0.99 95% CI 0.88–1.12 and RR 1.03, 95% CI 0.99–1.08, respectively).ConclusionsConsumption of processed meat, but not red meat, may increase the risk of breast cancer.

Optimal adjuvant endocrine treatment of ER+/HER2+ breast cancer patients by age at diagnosis: A population-based cohort study

Publication date: February 2018
Source:European Journal of Cancer, Volume 90
Author(s): G.M.H.E. Dackus, K. Jóźwiak, G.S. Sonke, E. van der Wall, P.J. van Diest, M. Hauptmann, S. Siesling, S.C. Linn
BackgroundPrior randomised controlled trials on adjuvant hormonal therapy included HER2any patients; however, a differential effect of aromatase inhibitors (AIs) versus tamoxifen (TAM) may have been missed in ER+/HER2+ patients that comprise 7–15% of all breast cancer patients.In addition, a woman's hormonal microenvironment may influence sensitivity to TAM and AIs in the adjuvant setting, which changes during menopausal transition, a process that takes years. We studied the efficacy of AIs versus TAM in ER+/HER2+ breast cancer patients grouped by age at diagnosis as a proxy for menopausal status using treatment and outcome data from the nationwide population-based Netherlands Cancer Registry (NCR).Patients and methodsAll women diagnosed between 2005 and 2007 with endocrine-treated, TanyNanyM0, ER+/HER2+ breast cancer were identified through the NCR (n = 1155). Patients were divided by age at diagnosis: premenopausal (≤45 years; n = 326), perimenopausal (45<years≤55; n = 304) and postmenopausal (>55 years; n = 525). A time-dependent variable, indicating whether AI or TAM was received for >50% of endocrine treatment duration, was applied to subdivide groups by predominant treatment received. Recurrence-free survival (RFS) and overall survival (OS) were assessed using Kaplan–Meier survival estimation and Cox regression. Hazard ratios (HRs) were adjusted for chemotherapy, trastuzumab, age at diagnosis, N-status, grade, pT-stage and ovarian ablation.ResultsDuring follow-up, 237 recurrences and 182 deaths occurred. Perimenopausal women derived significant RFS and OS benefit from AI compared with TAM, HR 0.47 (95% CI 0.25–0.91; P = 0.03) and HR 0.37 (95% CI 0.18–0.79; P = 0.01), respectively, whereas premenopausal women derived no benefit from AI compared with TAM. Treatment effects differed significantly between these age groups (interaction P = 0.03 and P = 0.02, respectively). Among postmenopausal women a small but non-significant AI benefit was observed.ConclusionAI treatment, preferably without any TAM treatment, was associated with the best RFS and OS outcome in ER+/HER2+ perimenopausal breast cancer patients.

IntroductionPrognosis of neuroblastoma patients is very diverse, indicating the need for more accurate prognostic parameters. The excretion of catecholamine metabolites by most neuroblastomas is used for diagnostic purposes, but their correlation with prognosis has hardly been investigated. Therefore, we performed an in-depth analysis of a panel of elevated urinary catecholamine metabolites at diagnosis and their correlation with prognosis.Patients and methodsRetrospective study of eight urinary catecholamine metabolites in a test (n = 96) and validation (n = 205) cohort of patients with neuroblastoma (all stages) at diagnosis.ResultsMultivariate analyses, including risk factors such as stage and MYCN amplification, revealed that 3-methoxytyramine (3MT) was an independent risk factor for event-free survival (EFS) and overall survival (OS). Furthermore, only 3MT appeared to be an independent risk factor for both EFS and OS in high-risk patients, which was independent of modern high-risk therapy and immunotherapy. Among high-risk patients, those with elevated 3MT and older than 18 months had an extremely poor prognosis compared to patients with non-elevated 3MT and younger than 18 months (5-year EFS of 14.3% ± 4% and 66.7% ± 18%, respectively, p = 0.001; 5-year OS of 21.8% ± 5% and 87.5% ± 12%, respectively, p < 0.001).ConclusionsElevated 3MT at diagnosis was associated with high-risk disease and poor prognosis. For high-risk patients, elevated 3MT at diagnosis was the only significant risk factor for EFS and OS. 3MT was also able to identify subgroups of high-risk patients with favourable and extremely poor prognosis.

Long-term follow-up of retinoblastoma survivors: Experience from India

Rachna Seth, Amitabh Singh, Vijay Guru, Bhavna Chawla, Sushmita Pathy, Savita Sapra

South Asian Journal of Cancer 2017 6(4):176-179

Background: Retinoblastoma (Rb) is the most common primary intraocular tumor of infancy and childhood. Survivors' ocular and visual problems and increased risk for subsequent malignancy are well documented, but data on long-term health status of Rb survivors are limited, this being particularly true for India. Methodology: Children who had completed treatment for Rb at least 2 years ago before and were under follow-up at the after cancer treatment clinic were evaluated. Results: In our series of 213 patients, the median age was 29 months, there was a male preponderance, and majority had unilateral disease. Enucleation was done in almost three-fourth and 3% underwent bilateral enucleation. Majority of the patients received chemotherapy, and few received radiation. Growth was affected in about one-third and majority were those who had received radiation. Diminished vision was noticed in about one-sixth. Orbital hypoplasia and contracted socket were seen in 14.1% cases. 2.7% were hearing impaired. About one-sixth had a global intelligence delay. Second neoplasms were seen in 0.01%. No other abnormalities were seen. Conclusions: Common late effects in our Rb survivors include diminished vision in the salvage eye, intellectual disability, and contracted socket; there is a need for timely institution of prosthesis to avoid late effects such as hypoplasia, contracted sockets, and better cosmesis and enhanced self-esteem. Second neoplasm is a concern. Lifelong follow-up and counseling of a healthy lifestyle are needed for Rb survivors.

Ajay R Upadhyay, Nikunj Chandrakant Desai, Digish U Vaghela

South Asian Journal of Cancer 2017 6(4):139-140

Aim: The aim of the study was to evaluate efficacy of percutaneous computed tomography (CT)-guided radiofrequency ablation (RFA) of nidus in osteoid osteoma (OO). Materials and Methods: RFA was performed on fifty patients with clinically and radiologically diagnosed OO. RFA was done in the department of radio-diagnosis in our institute (a tertiary care providing institute in Ahmedabad, Western India). Ablation was performed by putting at an electrode tip (3–5 mm) into nidus under CT guidance with targeted temperature of 90°C for 3 min. Results: All procedures were technically successful. No immediate major or minor complications were observed. Complete clinical success was achieved in 46 patients. Only four patients required second intervention. Conclusion: Our experience indicates a 98% success rate. No major complications were noted.

Dharma Ram, Suhas K Rajappa, Veda P Selvakumar, Himanshu Shukla, Ashish Goel, Rajeev Kumar, Kapil Kumar

South Asian Journal of Cancer 2017 6(4):141-143

Aim: Present study was done with an aim to analyse the clinicopathological and survival characteristics of male breast cancer patients. Methods: We did a retrospective review of our database and analysed total 27 patients who presented to breast oncology unit of Rajiv Gandhi cancer centre and research institute from January 2010 to April 2016. Results: Most common stage at presentation in our study was in stage II. The median follow up was 32.75 months. The actuarial 5-year survival was 92.30% and DFS was 76.30%. Only hormone receptor status was found as a significant prognostic variable among the prognostic factors studied for disease free survival. Conclusions: Carcinoma breast in male is a relatively rare disease and management principles are translated from our understanding of breast cancer in women. A relatively early stage at presentation is a contrasting finding of our series which may be responsible for a significantly better actuarial 5 year survival rates.

Vikas Ostwal, Tarachand Gupta, Supriya Chopra, Sherly Lewis, Mahesh Goel, Shraddha Patkar, Nitin Shetty, Anant Ramaswamy

South Asian Journal of Cancer 2017 6(4):144-146

Background: The current standard of treatment for advanced hepatocellular cancer Hepatocellular carcinoma (HCC) is Sorafenib. Data regarding its tolerance and adverse event profile in Indian patients is scarce. Materials and Methods: The primary aim of this analysis was to assess the adverse events (Grade 3 and Grade 4 as per CTCAE v4.0) and requirements for dose reduction with sorafenib in advanced HCC. Details of consecutive patients started on 800 mg/day dosing were obtained from a prospectively maintained database (over a period of 6 months) and analyzed. Results: Thirty-nine patients were available for inclusion in the study. Median age was 58 years (range: 20–75). All patients were classified as Barcelona clinic liver cancer C. Common side effects seen were liver dysfunction (38.5%), hand-foot-syndrome-rash (HFSR) (Grade 2 and 3-25.6%), fatigue (Grade 2 and Grade 3–10.3%), and diarrhea (7.7%). Dose reduction was required in 43.6% of patients. Drug interruptions/cessation was required in 38.5% of patients within the first four months of treatment. Nearly 41% of patients required cessation of sorafenib due to intolerable side-effects while 28.2% stopped sorafenib due to progressive disease. At a median follow-up of 4.9 months, median event-free survival (EFS) was 4.20 months (95% confidence interval: 3.343–5.068). Conclusion: A higher incidence of liver dysfunction and HFSR is seen in Indian patients as compared to published data. A significant proportion of patients required cessation of sorafenib due to adverse events in our series. However, EFS remains on par with that seen in larger studies with sorafenib in advanced HCC.

Arvind Sahu, Anant Ramaswamy, Nitin Singhal, Vipul Doshi, Jimmy Mirani, Ashwin Desouza, Shripad Banavali, Avanish Saklani, Vikas Ostwal

South Asian Journal of Cancer 2017 6(4):147-150

Aim: Data regarding the optimal management of metastatic anorectal melanoma (mARM) is scarce. The primary aim was to evaluate the potential benefits of systemic therapy in mARM. Materials and Methods: This is a retrospective analysis of all mARM who presented between July 2013 and June 2015 at the Department of GI Medical Oncology, Tata Memorial Hospital. Results: Of a total of 37 patients, twelve patients were planned for best supportive care (BSC) only while the remaining 25 patients received systemic therapy. The median overall survival (OS) for the whole cohort was 27 weeks. The OS was significantly better in patients who received first-line therapy as compared to those who were offered BSC (median OS: 14 vs. 33 weeks; P = 0.04). Patients with PS of 1 did significantly better than PS of 2 more (OS 70 vs. 17 weeks; P = 0.015). Conclusion: mARM should be offered chemotherapy, especially in good performance patients. Paclitaxel/Platinum or Capecitabine/Temozolomide regimens can be considered as the preferred regime in the resource-limited setting where immunotherapy may not be a feasible option.

Virender Suhag, BS Sunita, Pankaj Vats, Nilotpal Chakravarty, Mayuri Jain, Rekha S Vashisht

South Asian Journal of Cancer 2017 6(4):190-193

Background: Palliative radiotherapy (PRT) plays a significant role in the palliation of symptoms in patients with cancer and constitutes nearly 50% of the workload in different settings. Aims: The aim is to study patient-, disease-, and treatment-related characteristics in locoregionally advanced and metastatic malignancies meriting palliative management. Setting and Design: This was a retrospective observational study in a tertiary care government institute with academic and research potential. Methodology: The electronic medical records, medical documents, and radiotherapy (RT) treatment charts were retrieved and studied. Observations: A total of 460 patients were included in the study over 2 years, forming 30% of the total number of patients treated during the study period. Three hundred and ninety-six patients received PRT to the metastatic sites, while 64 patients received extremely hypofractionated PRT to the primary for symptomatic relief. Totally 442 patients showed good symptomatic response to PRT. One hundred and thirty-eight patients underwent re-irradiation. Lung was the most common primary site seen in 155 cases. The most common indication for PRT was palliation of pain from painful metastases as seen in 240 cases, and the next common indication was palliative whole-brain RT for brain metastases as seen in 159 cases. Conclusion: PRT forms an integral and important aspect of palliative care to the vast number of patients harboring metastatic disease that warrants some form of treatment for symptomatic relief. Short course of PRT in outdoor setting is a preferred mode of treatment to improve the quality of life of these distressed patients.

Regional reporting of the incidence of Anaplastic Lymphoma Kinase mutation in 379 non-small-cell lung cancer patients from Kolkata: Using immunohistochemistry as the diagnostic modality in a significant subset

Koushik Chatterjee, Raja Bhowmik, Bhargab Chattopadhyay

South Asian Journal of Cancer 2017 6(4):169-170

Context: Regional epidemiology of anaplastic lymphoma kinase (ALK) mutation in non-small-cell lung cancer (NSCLC) is an unmet need in India, and so is the knowledge of its incidence based on immunohistochemistry (IHC). Aims: Reporting the incidence of ALK mutation in NSCLC from Kolkata, incorporating IHC as the diagnostic modality in a considerable subset of patients. Subjects and Methods: It is a retrospective observational study done on NSCLC patients with adenocarcinoma histology, unselected by epidermal growth factor receptor, whose samples were tested for ALK mutation status between March 1, 2013, and March 15, 2017. The study involved all cancer facilities in Kolkata, except Tata Medical Centre. Up to June 2015, the tests were done by fluorescence in situ hybridization (FISH) and from July 2015 to the end, tests were done using IHC, as per the standard testing guidelines existing during the respective time periods. Results were documented in a de-identified manner to analyze the incidence of ALK mutations. Results: A total of 379 patients was tested for ALK mutations. March 2013 to June 2015, 200 (52.77%) patients were tested by FISH, 17 (8.5%) samples were unreportable and 4 patients [(2.19%) 4/183] tested positive for ALK mutations. From July 2015 to March 2017, 179 (47.22%) patients were tested by IHC, 9 (5.02%) samples were unreportable, and 10 patients [(5.88%) 10/170] tested positive for ALK mutations. Overall, 26 (6.8%) samples were unreportable and 14 [(3.9%) 14/353] patients tested positive for ALK mutations. Conclusions: The overall incidence of ALK mutation positive NSCLC in Kolkata is 3.9%. The incidence by IHC is 5.88% and by FISH is 2.19%, in the subset of patients tested by these two modalities respectively.

Suresh Babu Mallekavu, Aditi Harsh Thanky, Govind Babu Kanakasetty, Lakshmaiah Kuntegowdanahalli, Lokanatha Dasappa, Linu A Jacob

South Asian Journal of Cancer 2017 6(4):151-153

Context: Carcinoma cervix is a leading cause of cancer in Indian females where 15%–60% of the cases eventually metastasize. Bone only metastasis is rare, and data on its response and survival with systemic therapy as compared to other visceral metastasis are limited. Settings and Design: The study design was a retrospective analysis. Materials and Methods: We retrospectively analyzed our data between May 2013 and April 2015 to identify the cases of bone only metastasis and visceral metastasis and tried to analyze their outcomes with paclitaxel- and carboplatin-based chemotherapy and bisphosphonates (for bone metastasis only). Results: Totally, 12 cases with bone only metastasis (Group 1) and 43 cases with visceral metastasis (Group 2) were identified. Most common sites of bone metastasis were vertebrae (66.67%) and pelvis (25%) while that of visceral metastasis was liver (44.18%) and lung (34.88%). Only 33.33% and 34.88% of cases in Group 1 and Group 2, respectively, could complete all six cycles of chemotherapy. Overall, response rates were 41.67% and 30.32% in Group 1 and Group 2, respectively. Median progression-free survival and overall survival (OS) were 10 months and 14 months, respectively, in Group 1 as compared to 4 months and 9 months, respectively, in Group 2. The difference in survival was statistically significant. Statistical Analysis Used: It was carried out by SPSS software version 20. Conclusion: Bone only metastasis is a rare and distinct entity with favorable outcomes as compared to visceral metastasis. However, disease remains aggressive and poor OS emphasizing the need of further research.

Randeep Singh, Nitesh Rohtagi

South Asian Journal of Cancer 2017 6(4):171-175

Aims: The primary objective of this study was to estimate the clinicopathological and molecular profile of lung cancer patients along with the evaluation of their clinical characteristics at a tertiary care hospital in Northern India. Subjects and Methods: A total of 421 patients with lung cancer histology who were treated at Max Super Speciality Hospitals were included in the study. The study protocol conforms to the ethical guidelines of the 1975 Declaration of Helsinki and permission was obtained from the Ethics Committee before the start of the study. Clinical characteristics and molecular profiling data were collected from the patient's medical records. Results: There were 330 (78.4%) men and 91 (21.6%) women with a median age of 62 years (range: 30–93 years). Of the 421 patients, 388 (92.2%) patients had the nonsmall cell lung cancer (NSCLC) histology whereas 33 (7.8%) patients were of SCLC histology. Histology and gender had a significant association with NSCLC and SCLC (P < 0.05). Epidermal growth factor receptor (EGFR) and echinoderm microtubule-associated protein like 4-anaplastic lymphoma kinase (EML4-ALK) fusion gene testing was done in 120 and 93 patients, respectively. Of the 120 patients, 24 (20%) cases were positive for EGFR mutations whereas EML4-ALK fusion gene was present in 8 (8.6%) out of 93 patients. Conclusions: Our study confirms the importance of molecular testing in the NSCLC patient subgroup with an aim to identify the exact molecular targets that can benefit from the newer generation of targeted therapies.

Epidemiology of cancer in young in central India: An analysis of rural cancer hospital data

Novak Gupta, Prakash Chitalkar, Renu Mishra, Ankur Punia

South Asian Journal of Cancer 2017 6(4):183-185

Background: Cancers in teenage and young adults (TYAs), though an increasing cause of mortality in our country, have been scarcely studied. The lack of studies of TYAs can significantly affect the outcomes of the youth in the prime of their lives. Aims: The aim of this study was to study the type of cancers in the TYA at a rural cancer center in central India. Design and Methods: A prospective study in the department of medical oncology, from the period of January 2013 till March 2016, was done. Data regarding socioepidemiological factors were collected for new cancer patients between the age group of 15–30 years in semi-structured questionnaire and from the hospital records. Cancers were classified according to the Birch classification. The cases were analyzed according to the epidemiological profile, classification of cancer, and age-wise distribution using descriptive analysis. Results: In this study, out of 5221 cancer patients, TYAs accounted for 327 (6.26%) with 189 males and 138 females (M: F– 1.37:1). The maximum cases were seen in 25–30 years' age group. Carcinoma was the most common malignancy (54.74%) with an increase from 19.56% in the 15–19 years' age group to 64.82% in the 25–30-year-old patients. Conclusion: The present study gives a glimpse of the TYA cancers in the central India. More than half of the young cancer patients suffer from carcinomas with about half of these being head and neck cancers.

Short message service prompted mouth self-examination in oral cancer patients as an alternative to frequent hospital-based surveillance

Sagar Vaishampayan, Akshat Malik, Prashant Pawar, Kavi Arya, Pankaj Chaturvedi

South Asian Journal of Cancer 2017 6(4):161-164

Introduction: Oral squamous cell carcinoma (OSCC) are amongst commonest cancer in the Indian sub-continent. After treatment, these patients require frequent followup to look for recurrences/second primary. Mouth Self Examination (MSE) has a great potential in all levels of prevention of oral cancer. However, the compliance to self-examination has been reported as poor. Mobile phone is a cheap and effective way to reach out to people. Short Message Service (SMS) is extremely popular can be a very effective motivational and interactive tool in health care setting. Methodology: We aimed to identify in adequately treated OSCC patients, the influence of health provider initiated SMS on the compliance to the MSE and to establish the efficacy of MSE by comparing patients' MSE interpretation via replies to the SMS with that of the experts' opinion on clinical examination status during follow up. Conclusion: We conclude that MSE can be very useful in adequately treated OSCC patients for evaluating disease status. All treated OSCC patients must be adequately educated for MSE as an integral part of treatment & follow-up protocol by the health provider facility. Health provider generated SMS reminders do improve motivation and compliance towards MSE but don't seem to reduce dropouts in follow up for large and diverse population like that in India.

Background: We are a tertiary care cancer center and have approximately 1000–1500 emergency visits by cancer patients undergoing treatment under the adult medical oncology unit each month. However, due to the lack of a systematic audit, we are unable to plan steps toward the improvement in quality of emergency services, and hence the audit was planned. Methods: All emergency visits under the adult medical oncology department in the month of July 2015 were audited. The cause of visit, the demographic details, cancer details, and chemotherapy status were obtained from the electronic medical records. The emergency visits were classified as avoidable or unavoidable. Descriptive statistics were performed. Reasons for avoidable emergency visits were sought. Results: Out of 1199 visits, 1168 visits were classifiable. Six hundred and ninety-six visits were classified as unavoidable (59.6%, 95% CI: 56.7–62.4), 386 visits were classified as probably avoidable visit (33.0%, 95% CI: 30.4–35.8) whereas the remaining 86 (7.4%, 95% CI: 6.0–9.01) were classified as absolutely avoidable. Two hundred and ninety-seven visits happened on weekends (25.6%) and 138 visits converted into an inpatient admission (11.9%). The factors associated with avoidable visits were curative intention of treatment (odds ratio - 2.49), discontinued chemotherapy status (risk ratio [RR] - 8.28), and private category file status (RR – 1.89). Conclusion: A proportion of visits to emergency services can be curtailed. Approximately one-fourth of patients are seen on weekends, and only about one-tenth of patients get admitted.

Case report of Schöpf–Schulz–Passarge syndrome resulting from a missense mutation, p.Arg104Cys, in WNT10A

Abstract

Schöpf–Schulz–Passarge syndrome (SSPS) is a rare ectodermal dysplasia characterized by cysts of the eyelids, hypodontia, hypotrichosis, palmoplantar keratosis and onychodystrophy, and it is not common in Asia according to the published work. This autosomal recessive disorder was believed to result from mutations in the WNT10A gene. We report a 54-year-old Taiwanese man with SSPS resulted from a homozygous mutation (p.Arg104Cys) in WNT10A. This mutation has not been reported in odonto-onycho-dermal dysplasia but was demonstrated to link with dental abnormalities. This report implies the significance of WNT10A gene mutation in ectodermal dysplasia and highlights the clinical features of SSPS.

Vonoprazan- vs proton-pump inhibitor-based first-line 7-day triple therapy for clarithromycin-susceptible Helicobacter pylori: A multicenter, prospective, randomized trial

Abstract

Background

The eradication rate of vonoprazan-based first-line triple therapy (combined with clarithromycin and amoxicillin) (V-AC) was reported to be 97.6% in patients with clarithromycin (CAM)-susceptible Helicobacter pylori in a phase III study, whereas our real-world, prospective, multicenter cohort study yielded an eradication rate <90%.

Objective

To validate the eradication rate of V-AC using CAM-susceptible testing in a multicenter, prospective, randomized trial.

Methods

We included 147 treatment-naïve H. pylori-positive patients [41 with CAM-resistant infections and 106 with CAM-susceptible infections]. The CAM-susceptible group patients were randomized to either the V-AC group (vonoprazan 20 mg bid, amoxicillin 750 mg bid, and clarithromycin 200 or 400 mg bid) or PPI-AC group (lansoprazole 30 mg, rabeprazole 10 mg, or esomeprazole 20 mg bid; amoxicillin 750 mg bid; and clarithromycin 200 or 400 mg bid). All CAM-resistant H. pylori were eradicated by V-AC, as measured by the urea breath test around 8 weeks after eradication. Safety was evaluated by patient questionnaires.

Results

The intention-to-treat and per-protocol eradication rates of V-AC in the CAM-susceptible H. pylori-infected patients were 87.3% (95% confidence interval 75.5%-94.7%) and 88.9% (77.4%-95.8%). The respective eradication rates of PPI-AC were 76.5% (62.5%-87.2%) and 86.7% (73.2%-94.9%). No significant difference was observed between the V-AC and PPI-AC regimes in terms of the intention-to-treat (P = .21) or per-protocol (P = .77) analyses. The questionnaire scores did not differ significantly between the groups. Both the intention-to-treat and per-protocol eradication rates of V-AC in the CAM-resistant patients were 82.9% (67.9%-92.8%).

Conclusion

The eradication rate of V-AC treatment in the CAM-susceptible H. pylori-infected patients was <90%, as was that by PPI-AC, thus V-AC is not ideal regimen in CAM-susceptible H. pylori. However, the 82.9% eradication rate of V-AC in the CAM-resistant infections may indicate the potential of V-AC with modified dose, dosing interval, and treatment duration. (UMIN000016337).

Neutrophilic urticarial dermatosis: a novel association with poststreptococcal rheumatic disease

Summary

Neutrophilic urticarial dermatosis (NUD), a particular clinical and histological entity, can provide a strong pointer to underlying systemic disease, most frequently rheumatological diseases. We report the first case of NUD in association with a post-streptococcal rheumatic disease, with symptoms including recurrent sore throat, raised antistreptolysin O titre, persistent transient urticaria, polyarthralgia, rheumatic mitral valve disease and Jaccoud arthropathy. Histologically, NUD is characterized by an intense superficial and deep neutrophilic interstitial and perivascular infiltrate, without significant oedema or blood vessel damage. These neutrophils may have a tendency to concentrate along the basement membrane and extend into the epidermis, hair follicles, sebaceous glands and sweat glands (a feature termed 'neutrophilic epitheliotropism'). Clinicians should remain cognizant of NUD, and in particular its frequent association with an underlying inflammatory disorder.

Rational ideation and empiric validation of an innovative digital dermographic tester

Summary

Background

Dermographism is a condition characterized by a weal response to a combination of pressure and traction on skin surface, and its diagnosis is based on medical history, clinical criteria and provocation test. The Dermographic Tester®, a pen-sized tool containing a spring-loaded blunt tip, is the most widely used instrument for the provocation test, and it exerts increasing pressures on the skin surface according to an arbitrary units (AU) scale. Analysing the mechanism of function and trying to convert the AUs to SI units (g/mm2), we found that this instrument had some defects and limits that would compromise a true and repeatable quantification of the weal response threshold. Consequently, we decided to develop a new instrument, the Digital Dermographic Tester (DDT), which is engineered with an inside force sensor to implement features lacking in the current tools, in the hope of enhancing the precision of the provocation test.

Aim

To validate the effectiveness and accuracy of the DDT.

Methods

We tested the DDT on 213 participants purposely sampled to obtain three groups, each with a different pattern of reaction to mechanical stimuli. Based on anamnestic, diagnostic and symptomatic criteria, patients were divided into dermographic urticaria (DU), spontaneous urticaria (SU) and healthy control (HC) groups. The DDT was used to apply 12 levels of pressure to the skin surface, and a frequency distribution of positive reactions was displayed for each group.

Results

A force of 36–40 g/mm2 appropriately differentiated physiological from pathological conditions with high sensitivity and specificity.

Conclusions

The DDT was found to be capable of differentiating patients with DU patients from those with SU and from HCs, and was able to precisely identify the weal elicitation threshold.

Rationale and ObjectivesBecause it is imperative for understanding the performance of dual-energy computed tomography scanner to determine clinical diagnosis, we aimed to assess the accuracy of quantitative measurements using dual-energy computed tomography with fast kilovoltage switching.Materials and MethodsQuantitative measurements were performed for 16 reference materials (physical density, 0.965–1.550 g/cm3; diameter of rod, 2.0–28.5 mm; iodine concentration, 2–15 mg/mL; and calcium concentration, 50–300 mg/mL) with varying scanning settings, and the measured values were compared to their theoretical values.ResultsFor high-density material, the maximum differences in Hounsfield unit values in the virtual monochromatic images at 50, 70, and 100 keV were −176.2, 61.0, and −35.2 HU, respectively, and the standard deviations over short- and long-term periods were 11.1, 6.1, and 3.5 HU at maximum. The accuracy of the Hounsfield unit measurement at 50 and 70 keV was significantly higher (P < 0.05) with higher radiation output and smaller phantom size. The difference in the iodine and calcium measurements in the large phantom were up to −2.6 and −60.4 mg/mL for iodine (5 mg/mL with 2-mm diameter) and calcium (300 mg/mL) materials, and the difference was improved with a small phantom. Metal artifact reduction software improved subjective image quality; however, the quantitative values were significantly underestimated (P < 0.05) (−49.5, −26.9, and −15.3 HU for 50, 70, and 100 keV, respectively; −1.0 and −17 mg/mL for iodine and calcium concentration, respectively) compared to that acquired without a metal material.ConclusionsThe accuracy of quantitative measurements can be affected by material density and the size of the object, radiation output, phantom size, and the presence of metal materials.

Author(s): Colleen H. Neal, Kelsey A. Flynt, Deborah O. Jeffries, Mark A. Helvie
Rationale and ObjectivesThe study aimed to determine the outcome of patients presenting for evaluation of abnormal breast thermography.Materials and MethodsFollowing Institutional Review Board approval, retrospective search identified 38 patients who presented for conventional breast imaging following a thermography-detected abnormality. Study criteria included women who had mammogram and/or breast ultrasound performed for evaluation of a thermography-detected abnormality between January 1, 2000, and December 31, 2015. Patients whose mammograms and ultrasounds were initiated at an outside institution or who did not have imaging at our institution were excluded. Records were reviewed for clinical history, thermography results, mammogram and/or ultrasound findings, and pathology. Mammograms and ultrasounds were prospectively interpreted by one of 14 Mammography Quality Standards Act–certified breast imaging radiologists with 3–30 years of experience. Patient outcomes were determined by biopsy or at least 1 year of follow-up. Patient ages ranged from 23 to 70 years (mean = 50 years).ResultsNinety-five percent (36 of 38) of patients did not have breast cancer. The two patients diagnosed with breast cancer had suspicious clinical symptoms including palpable mass and erythema. No asymptomatic woman had breast cancer. Negative predictive value was 100%. Of 38 patients, 79% (30 of 38) had Breast Imaging Reporting and Data System (BI-RADS) 1 or 2 assessments; 5% (2 of 38) had BI-RADS 3; and 16% (6 of 38) had BI-RADS 4 (n = 5) or BI-RADS 5 (n = 1) assessments. Two of six patients with biopsy recommendations were diagnosed with breast cancer (Positive predictive value 2 = 33.3%). All findings recommended for biopsy were ipsilateral to the reported thermography abnormality.ConclusionsNo cancer was diagnosed among asymptomatic women. The 5% of patients diagnosed with cancer had co-existing suspicious clinical findings. Mammogram and/or ultrasound were useful in accurately characterizing patients with abnormal thermography.

Autophagy and proteostasis in the control of synapse aging and disease

S09594388.gif

Publication date: February 2018

Author(s): YongTian Liang, Stephan Sigrist
The maintenance of neuronal homeostasis is severely threatened by aging, probably partially due to compromised autophagic clearance. Hence, rejuvenating autophagy in aging neurons is considered a promising strategy to restore cognitive performance. Research in recent years has shown that autophagosome biogenesis takes place mainly in distal axons and, thus, close to presynaptic specializations, and that efficient macro-autophagy is essential for neuronal homeostasis and survival. Retrograde transport of autophagosomes might play a role in neuronal signaling processes, promoting neuronal complexity and preventing neurodegeneration. Here, we discuss recent advances concerning the intersection of aging, neurodegeneration and autophagy, and try to create a unified view of how neuronal autophagy and proteostasis might control synaptic aging and disease.

Direct cardiac reprogramming holds great promise for regenerative medicine. We previously generated directly reprogrammed induced cardiomyocyte-like cells (iCMs) by overexpression of Gata4, Mef2c, and Tbx5 (GMT) using retrovirus vectors. However, integrating vectors pose risks associated with insertional mutagenesis and disruption of gene expression and are inefficient. Here, we show that Sendai virus (SeV) vectors expressing cardiac reprogramming factors efficiently and rapidly reprogram both mouse and human fibroblasts into integration-free iCMs via robust transgene expression. SeV-GMT generated 100-fold more beating iCMs than retroviral-GMT and shortened the duration to induce beating cells from 30 to 10 days in mouse fibroblasts. In vivo lineage tracing revealed that the gene transfer of SeV-GMT was more efficient than retroviral-GMT in reprogramming resident cardiac fibroblasts into iCMs in mouse infarct hearts. Moreover, SeV-GMT improved cardiac function and reduced fibrosis after myocardial infarction. Thus, efficient, non-integrating SeV vectors may serve as a powerful system for cardiac regeneration.

Radial Glial Fibers Promote Neuronal Migration and Functional Recovery after Neonatal Brain Injury

Radial glia (RG) are embryonic neural stem cells (NSCs) that produce neuroblasts and provide fibers that act as a scaffold for neuroblast migration during embryonic development. Although they normally disappear soon after birth, here we found that RG fibers can persist in injured neonatal mouse brains and act as a scaffold for postnatal ventricular-subventricular zone (V-SVZ)-derived neuroblasts that migrate to the lesion site. This injury-induced maintenance of RG fibers has a limited time window during post-natal development and promotes directional saltatory movement of neuroblasts via N-cadherin-mediated cell-cell contacts that promote RhoA activation. Transplanting an N-cadherin-containing scaffold into injured neonatal brains likewise promotes migration and maturation of V-SVZ-derived neuroblasts, leading to functional improvements in impaired gait behaviors. Together these results suggest that RG fibers enable postnatal V-SVZ-derived neuroblasts to migrate toward sites of injury, thereby enhancing neuronal regeneration and functional recovery from neonatal brain injuries.

Bone marrow vascular niches sustain hematopoietic stem cells (HSCs) and are drastically remodeled in leukemia to support pathological functions. Acute myeloid leukemia (AML) cells produce angiogenic factors, which likely contribute to this remodeling, but anti-angiogenic therapies do not improve AML patient outcomes. Using intravital microscopy, we found that AML progression leads to differential remodeling of vasculature in central and endosteal bone marrow regions. Endosteal AML cells produce pro-inflammatory and anti-angiogenic cytokines and gradually degrade endosteal endothelium, stromal cells, and osteoblastic cells, whereas central marrow remains vascularized and splenic vascular niches expand. Remodeled endosteal regions have reduced capacity to support non-leukemic HSCs, correlating with loss of normal hematopoiesis. Preserving endosteal endothelium with the small molecule deferoxamine or a genetic approach rescues HSCs loss, promotes chemotherapeutic efficacy, and enhances survival. These findings suggest that preventing degradation of the endosteal vasculature may improve current paradigms for treating AML.

A novel hydrophilic pyridinium salt polymer/SWCNTs composite film for high thermoelectric performance

Publication date: Available online 21 December 2017

Author(s): Sanyin Qu, Qin Yao, Liming Wang, Jianli Hua, Lidong Chen
Polymer/carbon nanotube composites have gained great progress in the past decade. However, the lack of scalability of production due to the relatively high volatility and strong toxicity of the dispersion solvent have created a great need for environmental friendly process for expanding TE applications. In this work, organic-inorganic composite films composed of a novel hydrophilic pyridinium salt polymer (noted as P2) and SWCNTs were prepared for thermoelectric application. The novel hydrophilic pyridinium salt polymer was designed and synthesized containing the pyridinium salt for aqueous dissolution and thiophenes as the conjugation group to make the polymer/CNT composite film electrical connecting, therefore improving the thermoelectric performance. Another pyridinium salt polymer (noted as P1) without thiophene group was also synthesized for the purpose of comparison. The polymers attach on the surface of CNTs through π-π conjugation interaction between conjugation groups and π-electrons of CNTs. The P2/CNT composites were homogeneously dispersed in the aqueous solution, revealing better dispersion behavior than P1/CNT, which is probably because of the stronger contact interaction between P2/CNT than P1/CNT due to the higher electron delocalization of polymer P2 than P1. The electrical conductivity of P2/CNT composite film reached the maximum value of 159 S/cm with 50% CNT content. Consequently, a high power factor of 46.4 μW/mK2 was obtained for the P2/50%CNT composite film.

Automatic, simultaneous control of polymer composition and molecular weight during free radical copolymer synthesis

Publication date: Available online 21 December 2017
Source:Polymer
Author(s): Terry McAfee, Rick D. Montgomery, Thomas Zekoski, Aide Wu, Wayne F. Reed
Fully automatic, simultaneous control of polymer composition and molecular weight trajectories during free radical copolymer synthesis was achieved by coupling the continuous ACOMP data stream into a feedback controller which operated pumps for reactor feed of comonomers. The controller operates without recourse to a detailed kinetic model or reactivity ratios. Rather, it uses the fact that instantaneous copolymer chain composition is related to the instantaneous rate of consumption of comonomers, and the rate for each of these is described by rates α1 and α2 for comonomers 1 and 2, respectively. The instantaneous weight average molecular weight Mw,inst is proportional to total comonomer concentration via a constant p. Hence, target trajectories for composition and Mw can be independently prescribed and followed. Since α1, α2 and p are directly measurable from the ACOMP data stream, their values can be constantly updated by the automatic controller during the reaction process to insure the target trajectories are followed.

We evaluated the role of vertebral artery extracranial color-coded duplex sonography (VAECCS) in predicting vertebrobasilar stroke in consecutive patients presenting to the emergency department with vertigo of suspected ischemic origin. The final diagnosis was established by a panel of experts consisting of an emergency physician, a neurologist, and an otoneurologist. Vertebrobasilar stroke was diagnosed when an acute brain ischemic lesion congruent with symptoms was detected by neuroimaging during the index visit or a stroke was diagnosed within a 3-mo period after emergency department presentation. Among 126 patients, 28 (22%) were diagnosed with vertebrobasilar stroke. Fifteen (75%) of 20 patients with abnormal VAECCS results and 13 (12%) of 106 with normal VAECCS results had a final diagnosis of vertebrobasilar stroke. The sensitivity and specificity of VAECCS were 53.6% and 94.9%, respectively. Detecting an abnormal flow pattern at VAECCS significantly increased the risk of vertebrobasilar stroke (odds ratio = 21.5). The flow patterns most frequently related to vertebrobasilar stroke were absence of flow and high resistance pattern velocity (odds ratio = 9.3 and 22.7, respectively). VAECCS predicts vertebrobasilar stroke and could be a useful bedside screening tool in patients with vertigo.

Ultrasound (US) can be used to noninvasively stimulate brain activity. However, reproducible motor responses evoked by US are only elicited when the animal is in a light state of anesthesia. The present study investigated the effects of ketamine on US-induced motor responses and cortical neuronal activity. US was applied to the motor cortex of mice, and motor responses were evaluated based on robustness scores. Cortical neuronal activity was observed by fluorescence calcium imaging. US-induced motor responses were inhibited more than 20 min after ketamine injection, and US-triggered Ca2+ transients in cortical neurons were effectively blocked by ketamine. Our results indicate that ketamine suppresses US-triggered Ca2+ transients in cortical neurons and, therefore, inhibits US-induced motor responses in a deep anesthetic state.

The jugular venous pulse (JVP) is one of the main parameters of cardiac function and is used by cardiologists in diagnosing heart failure. Its waveform comprises three positive waves (a, c and v) and two negative waves (x and y). Recently, it was found that JVP can be extrapolated from an ultrasound (US) video recording of the internal jugular vein (IJV), suggesting its application in space missions, on which US scanners are already widely used. To date, the feasibility of assessing JVP in microgravity (microG) has not been investigated. To verify the feasibility of JVP assessment in microG, we tested a protocol of self-performed B-mode ultrasound on the International Space Station (ISS). The protocol consisted of a video recording of IJV synchronized with electrocardiogram that produces a cross-sectional area time trace (JVP trace) (in cm2). The scans were acquired in six experimental sessions; two pre-flight (BDC1 and -2), two in space (ISS1 and -2) and two post-flight (Houston PF1, Cologne PF2). We measured the mean and standard deviation of the JVP waves and the phase relationship between such waves and P and T waves on the electrocardiogram. We verified that such parameters had the same accuracy on Earth as they did under microG, and we compared their values. The sensitivity, specificity and accuracy of JVP trace in microgravity are higher than those on Earth. The sequence of (a, c, and v) ascents and (x and y) descents along the cardiac cycle in microG is the same as that on Earth. The cause-and-effect relationship between the P and T waves on the electrocardiogram and a and v waves, respectively, of JVP is also confirmed in microG. Our experiment indicated the feasibility of deriving a JVP trace from a B-mode US examination self-performed by an astronaut in microG.

Multiple time courses of somatosensory responses in human cortex

Author(s): P. Avanzini, V. Pelliccia, G. Lo Russo, G.A. Orban, G. Rizzolatti
Here we show how anatomical and functional data recorded from patients undergoing stereo-EEG can be used to decompose the cortical processing following nerve stimulation in different stages characterized by specific topography and time course. Tibial, median and trigeminal nerves were stimulated in 96 patients, and the increase in gamma power was evaluated over 11878 cortical sites. All three nerve datasets exhibited similar clusters of time courses: phasic, delayed/prolonged and tonic, which differed in topography, temporal organization and degree of spatial overlap. Strong phasic responses of the three nerves followed the classical somatotopic organization of SI, with no overlap in either time or space. Delayed responses presented overlaps between pairs of body parts in both time and space, and were confined to the dorsal motor cortices. Finally, tonic responses occurred in the perisylvian region including posterior insular cortex and were evoked by the stimulation of all three nerves, lacking any spatial and temporal specificity. These data indicate that the somatosensory processing following nerve stimulation is a multi-stage hierarchical process common to all three nerves, with the different stages likely subserving different functions. While phasic responses represent the neural basis of tactile perception, multi-nerve tonic responses may represent the neural signature of processes sustaining the capacity to become aware of tactile stimuli.

A probabilistic atlas of human brainstem pathways based on connectome imaging data

The brainstem is a critical structure that regulates vital autonomic functions, houses the cranial nerves and their nuclei, relays motor and sensory information between the brain and spinal cord, and modulates cognition, mood, and emotions. As a primary relay center, the fiber pathways of the brainstem include efferent and afferent connections among the cerebral cortex, spinal cord, and cerebellum. While diffusion MRI has been successfully applied to map various brain pathways, its application for the in vivo imaging of the brainstem pathways has been limited due to inadequate resolution and large susceptibility-induced distortion artifacts. With the release of high-resolution data from the Human Connectome Project (HCP), there is increasing interest in mapping human brainstem pathways. Previous works relying on HCP data to study brainstem pathways, however, did not consider the prevalence (>80%) of large distortions in the brainstem even after the application of correction procedures from the HCP-Pipeline. They were also limited in the lack of adequate consideration of subject variability in either fiber pathways or region of interests (ROIs) used for bundle reconstruction. To overcome these limitations, we develop in this work a probabilistic atlas of 23 major brainstem bundles using high-quality HCP data passing rigorous quality control. For the large-scale data from the 500-Subject release of HCP, we conducted extensive quality controls to exclude subjects with severe distortions in the brainstem area. After that, we developed a systematic protocol to manually delineate 1300 ROIs on 20 HCP subjects (10 males; 10 females) for the reconstruction of fiber bundles using tractography techniques. Finally, we leveraged our novel connectome modeling techniques including high order fiber orientation distribution (FOD) reconstruction from multi-shell diffusion imaging and topography-preserving tract filtering algorithms to successfully reconstruct the 23 fiber bundles for each subject, which were then used to calculate the probabilistic atlases in the MNI152 space for public release. In our experimental results, we demonstrate that our method yielded anatomically faithful reconstruction of the brainstem pathways and achieved improved performance in comparison with an existing atlas of cerebellar peduncles based on HCP data. These atlases have been publicly released on NITRIC (http://ift.tt/2kCIOlg) and can be readily used by brain imaging researchers interested in studying brainstem pathways.

With the abilities of self-renewal and differentiation, embryonic stem (ES) cells provide an unlimited source for stem cell-based therapeutics. However, the maintenance of ES cells with mouse embryonic fibroblasts (MEFs) can limit the clinical translation of ES cells. In the present study, we synthesized a fusion protein of the immunoglobulin G (IgG) fragment crystallizable region and vascular endothelial cadherin (VE-cadherin) extracellular domain (VE-cad-Fc) as a substrate for mouse ES cell culture, and we hypothesized that VE-cadherin could enhance the pluripotency and self-renewal of ES cells. Furthermore, we introduced a Stat3 reporter imaging system into ES cells and investigated the mechanism of the pluripotency enhancement mediated by VE-cadherin through cultured ES cells on VE-cad-Fc-coated plates using molecular imaging techniques. The resulting data revealed that VE-cad-Fc could activate the Stat3 signaling pathway, leading to the upregulation of stemness-related markers SSEA-1 and alkaline phosphatase (ALP). Moreover, VE-cad-Fc recovered the expression of Oct4, c-Myc, Nanog, Sox2, Tbx3 and Klf4 in differentiated ES cells, as well as enhanced the pluripotency of ES cells. In conclusion, VE-cadherin fusion protein coating methods provide an alternative towards feeder free culture of ES cells, and the strategy developed in the present study may benefit the clinical translation of ES cell-based therapeutics.

Precision design of nanomedicines to restore gemcitabine chemosensitivity for personalized pancreatic ductal adenocarcinoma treatment

Publication date: March 2018
Source:Biomaterials, Volume 158
Author(s): Xiao Zhao, Xiuchao Wang, Wei Sun, Keman Cheng, Hao Qin, Xuexiang Han, Yu Lin, Yongwei Wang, Jiayan Lang, Ruifang Zhao, Xiaowei Zheng, Ying Zhao, Jian shi, Jihui Hao, Qing Robert Miao, Guangjun Nie, He Ren
Low chemosensitivity considerably restricts the therapeutic efficacy of gemcitabine (GEM) in pancreatic cancer treatment. Using immunohistochemical evaluation, we investigated that decreased expression of human equilibrative nucleoside transporter-1 (hENT1, which is the major GEM transporter across cell membranes) and increased expression of ribonucleotide reductase subunit 2 (RRM2, which decreases the cytotoxicity of GEM) was associated with low GEM chemosensitivity. To solve these problems, we employed a nanomedicine-based formulation of cationic liposomes for co-delivery of GEM along with siRNA targeting RRM2. Due to the specific endocytic uptake mechanism of nanocarriers and gene-silencing effect of RRM2 siRNA, this nanomedicine formulation significantly increased GEM chemosensitivity in tumor models of genetically engineered Panc1 cells with low hENT1 or high RRM2 expression. Moreover, in a series of patient-derived cancer cells, we demonstrated that the therapeutic benefits of the nanomedicine formulations were associated with the expression levels of hENT1 and RRM2. In summary, we found that the essential factors of GEM chemosensitivity were the expression levels of hENT1 and RRM2, and synthesized nanoformulations can overcome these problems. This unique design of nanomedicine not only provides a universal platform to enhance chemosensitivity but also contributes to the precision design and personalized treatment in nanomedicine.

Anticholinergics for asthma: a long history

imagePurpose of review To provide a fast overview about the introduction and development of anticholinergic drugs in Western medicine to their current indications particularly in asthma. Recent findings Although short-acting muscarinic antagonists have been positioned in the last 15 years for the treatment of adults and children with moderate-to-severe acute asthma in the emergency setting (reducing the risk of hospital admissions and improving lung function), a growing body of evidence has recently emerged that positions the long-acting muscarinic anticholinergic tiotropium bromide as add-on therapy to at least inhaled corticosteroids (ICS) maintenance therapy in adults, adolescents, and children with symptomatic asthma. Thus, the addition of tiotropium bromide to ICS alone or ICS and another controller was associated with significant improvements in spirometric measures and asthma control, and a significantly decrease in the rate of asthma exacerbations. Summary Short-acting muscarinic antagonists and tiotropium bromide have a well established role in the treatment of different phases of asthma. Further data are needed to provide more evidence on other selective long-acting muscarinic antagonists in addition to tiotropium as potential treatment options.

Collection of nasal secretions and tears and their use in allergology

imagePurpose of review The identification of immunological markers in nasal secretions and tears is becoming essential in the study of allergic diseases. The collection procedure of nasal and ocular secretions directly influences the results, thus it is of paramount importance to validate and standardize the sampling process. Recent findings Current techniques for nasal secretions sampling are mainly based on three principles: collection of spontaneous secretions, nasal washings, and absorption. Collection of spontaneous secretions is appropriate in subjects with nasal hypersecretion, whereas in healthy individuals the collected volume is frequently insufficient. Nasal washings are associated with an unpredictable, high dilution and concentrations of markers often fall below detection limits of immunological assays. Absorption seem to provide the best compromise between sufficient sample amounts and detectability of inflammatory mediators and immunoglobulin E. Tear samples can be obtained by glass capillary tubes, filter paper strips and ophthalmic sponges. Volumes are however small or highly diluted through reflex tearing. Summary Secretions reflect the local inflammatory activity and provide valuable information about the immunological reaction to allergens at the target organ. There is increasing evidence of the potential clinical role of their analysis, for diagnosis, and monitoring of allergic rhino-conjunctivitis. Appropriate collection and processing is very important and requires special attention.

Asthma: personalized and precision medicine

imagePurpose of review In this review, we herein describe the progress in management of severe asthma, evolving from a 'blockbuster approach' to a more personalized approach targeted to the utilization of endotype-driven therapies. Recent findings Severe asthma characterization in phenotypes and endotypes, by means of specific biomarkers, have led to the dichotomization of the concepts of 'personalized medicine' and 'precision medicine', which are often used as synonyms, but actually have conceptual differences in meaning. The recent contribute of the omic sciences (i.e. proteomics, transcriptomics, metabolomics, genomics, …) has brought this initially theoretic evolution into a more concrete level. Summary This step-by-step transition would bring to a better approach to severe asthmatic patients as the personalization of their therapeutic strategy would bring to a better patient selection, a more precise endotype-driven treatment, and hopefully to better results in terms of reduction of exacerbation rates, symptoms, pulmonary function and quality of life.

Prevalence and clinical characteristics of local allergic rhinitis to house dust mites

imagePurpose of review Local allergic rhinitis (LAR) is a recently classified subtype of rhinitis defined by a nasal allergic response in patients without systemic evidence of atopy. Recent studies have reported the prevalence, clinical course, culprit allergens, diagnostic methods and treatment outcomes of LAR. The purpose of this review is to summarize the most relevant and updated scientific evidence for LAR, especially focusing on its prevalence and clinical characteristics. Recent findings LAR is found in a significant proportion (3.7–61.9%) of patients previously diagnosed with nonallergic rhinitis, but the prevalence may differ among ethnic groups and countries. Common allergens of LAR are similar to those of allergic rhinitis, in which house dust mites are the most common cause, followed by grass pollen, tree pollen, weed pollen and animal dander confirmed by provocation tests. Although the nasal provocation test to a single allergen is considered the gold standard method, the detection of allergen-specific IgE and other inflammatory mediators from nasal secretions and the basophil activation test can assist in the diagnosis of LAR. Conjunctivitis and asthma are the most common comorbid conditions, and the occurrence rate of asthma increases over period. However, the conversion rate to allergic rhinitis was not significantly different between LAR and healthy controls. Summary LAR is a well-differentiated entity of rhinitis, which should be considered in patients with persistent and severe symptoms without any systemic evidence of atopy. Further research is needed to investigate the long-term outcome, and geographic and ethnic differences of LAR.

Role of epigenetics and DNA-damage in asthma

imagePurpose of review Although asthma is a common disease worldwide, its pathogenesis remains to be fully elucidated. There is increasing evidence of the interaction between epigenetics, DNA-damage, and environmental allergens in the development of asthma. In this review, we will focus on the role of epigenetics and DNA-damage in asthma. Recent findings There is growing evidence of environmental allergens, particularly house dust mite, stimulating oxidative DNA damage in airway epithelial cells. The repair of this DNA damage has been implicated in the secretion of Th2 cytokines and the induction of allergic inflammation. Summary Studies of the role of epigenetics, DNA-damage, and environmental allergens have begun to reveal the their complex interactions and their roles in the development of asthma. Further study in these areas may lead to novel prevention and treatment approaches.

Association between allergic and nonallergic rhinitis and obstructive sleep apnea

imagePurpose of review Allergic rhinitis and nonallergic rhinitis (NAR) are common disorders, which have been considered as potential risk factors for obstructive sleep apnea (OSA). This review summarizes the proposed underlying pathophysiological mechanisms to provide a better understanding of the relationship between these conditions. Recent findings In adults, allergic rhinitis and NAR may be considered as symptoms potentiating, rather than risk potentiating factors in the pathophysiology of OSA, whereas in children, these are considered to be independent predictors for sleep-disordered breathing (SDB) and failure of adeno-tonsillectomy, the recommended first-line therapy for children with OSA. Current advances suggest IL-6 may be important in regulating the sleep–wake cycle, and serum soluble IL-6 receptor (sIL-6R) levels may reflect the severity of OSA. Elevated Th17/Treg ratio correlates positively with apnea–hypopnea index of OSA patients, and Th17 and Treg imbalances caused by allergic rhinitis and OSA, respectively, may possibly promote each other, leading to further imbalance. Moreover, obesity is a strong risk factor for OSA, and leptin plays an important role in ventilatory function and upper airway obstruction. The variant trigeminocardiac reflex and nasotrigeminal reflex may also be involved in the association between rhinitis and OSA. Summary Allergic rhinitis/NAR and OSA are closely associated, and each condition can be detrimental to the other. Thus, clinicians should pay attention to the potential presence of allergic rhinitis/NAR in OSA patients and vice versa.

Update on questionnaires for assessing adherence to inhaler devices in respiratory patients

imagePurpose of review It has been estimated that adherence to inhaled medications in patients with asthma and chronic obstructive pulmonary disease (COPD) is around 50%. This low adherence rate increases morbidity and mortality of these disorders. The objective of this review was to update information on main questionnaires used in daily for assessing adherence to inhalers of patients with chronic respiratory diseases. Recent findings The test of the adherence to inhalers (TAI) is a recently developed and validated 12-item questionnaire to assess adherence to inhalers of aerosolized drugs in patients with asthma or COPD. The instrument can easily identify nonadherence, classify the level of adherence into good, intermediate and poor, and establish three nonadherence behaviour patterns of erratic, deliberate, and unwitting, which are useful for tailoring corrective measures. Summary Adherence to inhaler devices may be underestimated with the use of validated self-report questionnaires as compared with other more sensitive methods. However, validated self-report questionnaires are more advantageous from a cost-effective perspective in clinical practice. The recently validated TAI is a reliable and homogeneous instrument to identify easily nonadherence and behavioural barriers to the use of inhalers in patients with asthma or COPD.

Asthma versus chronic obstructive pulmonary disease, the Dutch versus British hypothesis, and role of interleukin-5

imagePurpose of review Asthma and COPD represent heterogeneous disorders with broad ranging impact on patients and health systems. This review focuses on evidence for early attempts at understanding their pathogenesis by the British and Dutch hypotheses. It also addresses the role of eosinophils, IL-5, and biologics targeting these pathways in asthma and COPD. Recent findings Among asthma and COPD patients, clusters exist based on phenotypic and biologic markers allowing for further understanding of endotypes. Recent studies suggest the role of eosinophils and optimal therapies for each condition may be different. Summary Although patients with ACOS or overlap symptoms may be an exception, overall there appears to be more evidence supporting that asthma and COPD are distinct processes. Targeting eosinophils with anti-IL-5 therapy appears to be an exciting pathway in the properly selected patient with asthma and recent data also supports its use in COPD.

PURPOSEWe assessed the cost-effectiveness of adjuvant intravaginal brachytherapy (IVBT) vs. observation after total hysterectomy and bilateral salpingo-oophorectomy (TH/BSO) for high-intermediate risk (HIR) endometrial carcinoma.Methods AND MATERIALSA Markov model was used to assess the cost-effectiveness of IVBT by comparing average cumulative costs, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios (ICERs) between patients allocated to (1) 'observation' or (2) 'IVBT' after TH/BSO. We used a prototype Post-Operative Radiation Therapy in Endometrial Carcinoma (PORTEC)–defined HIR patient in the base case analysis. We calibrated the model to match the outcomes reported in the PORTEC-1 and PORTEC-2 trials. Utilities were obtained from published estimates, and costs were calculated based on Medicare reimbursement ($5445 for IVBT). The societal willingness-to-pay threshold was set at $100,000 per QALY. The time horizon was 5 years.ResultsIVBT was associated with a net increase of 0.094 QALYs (4.512 vs. 4.418) as well as an increase in mean cost ($17,453 vs. $15,620) relative to observation. The ICER for IVBT was $19,500 per QALY. On one-way sensitivity analysis, IVBT remained cost-effective when its cost was less than $12,937. If the probability of vaginal recurrence in the observation arm was increased or decreased by 25%, the ICER became $1335 per QALY and $87,925 per QALY, respectively. Probabilistic sensitivity analysis revealed that IVBT was the preferred management option in 86% of simulations.ConclusionsIVBT is cost-effective compared with observation after TH/BSO for HIR endometrial carcinoma by commonly accepted willingness-to-pay thresholds.

PURPOSEThis meta-analysis was conducted to investigate the efficacy and safety of 125I brachytherapy for locally advanced non–small cell lung cancer (NSCLC).Methods AND MATERIALSTrials comparing 125I brachytherapy with chemotherapy in NSCLC were identified. Meta-analysis was performed to obtain pooled risk ratios for an overall response rate (ORR), disease control rate (DCR) and complications, and pooled hazard ratio for overall survival (OS).ResultsFifteen studies including 1188 cases were included. The pooled result indicated that there were significant differences in ORR, DCR, and OS between 125I brachytherapy combined with chemotherapy and chemotherapy alone, but no statistic differences in gastrointestinal symptoms, leukopenia, myelosuppression, and hemoglobin reduction. Patients treated with 125I brachytherapy combined with chemotherapy have a higher relative risk of pneumothorax, bloody sputum, and pneumorrhagia compared with chemotherapy alone. Seeds migration only occurred in the group treated with 125I brachytherapy. There were significant differences in ORR, DCR, and myelosuppression between 125I brachytherapy alone and chemotherapy.Conclusions125I brachytherapy combined with chemotherapy can significantly enhance the clinical efficacy and improve the OS of patients with advanced NSCLC without increasing the incidence of complications of chemotherapy. 125I brachytherapy alone can significantly enhance the clinical efficacy and reduce the incidence of myelosuppression compared with chemotherapy. However, 125I brachytherapy may cause lung injury. Large sample and higher-quality randomized controlled trials are needed to confirm the pooled results of complications.

Mu-Opioid Receptors in Ganglia, But Not in Muscle, Mediate Peripheral Analgesia in Rat Muscle Pain

BACKGROUND: Previous studies have demonstrated the participation of peripheral μ-opioid receptors (MOR) in the antinociceptive effect of systemically administered morphine and loperamide in an orofacial muscle pain model, induced by hypertonic saline, but not in a spinally innervated one, in rats. In this study, we determine whether this peripheral antinociceptive effect is due to the activation of MOR localized in the muscle, ganglia, or both. METHODS: To determine the local antinociceptive effect of morphine and loperamide, 2 models of acute muscle pain (trigeminal and spinal) were used. Also, to study the MOR expression, protein quantification was performed in the trigeminal and spinal ganglia, and in the muscles. RESULTS: The behavioral results show that the intramuscular injection of morphine and loperamide did not exert an antinociceptive effect in either muscle (morphine: P = .63, loperamide: P = .9). On the other hand, MOR expression was found in the ganglia but not in the muscles. This expression was on average 44% higher (95% CI, 33.3–53.9) in the trigeminal ganglia than in the spinal one. CONCLUSIONS: The peripheral antinociceptive effect of systemically administered opioids may be due to the activation of MOR in ganglia. The greater expression of MOR in trigeminal ganglia could explain the higher antinociceptive effect of opioids in orofacial muscle pain than in spinal muscle pain. Therefore, peripheral opioids could represent a promising approach for the treatment of orofacial pain. Accepted for publication October 23, 2017.

Intravenous Iron for Treatment of Anemia in the 3 Perisurgical Phases: A Review and Analysis of the Current Literature

Anemia is a common comorbidity throughout the entire hospital stay. Treatment options include intravenous (IV) iron, oral iron, erythropoietin, and red blood cell (RBC) transfusions. IV iron has gained in popularity with the implementation of patient blood management programs. A variety of studies have been performed to investigate the use of IV iron in preoperative, perioperative, and postoperative settings. An objective review on these studies has yet to be performed. The current narrative review provides an overview of trials investigating IV iron use in the preoperative, perioperative, and postoperative settings. We performed a literature research of English articles published between 1964 and March 2017 in Pubmed including Medline and The Cochrane Library. Only studies with a control group were included. The final review includes 20 randomized controlled trials (RCTs), 7 observational trials, and 5 retrospective studies. Measured outcomes included hemoglobin (Hb) levels, reticulocyte counts, and/or RBC concentrates. Meta-analyses of RCTs using IV iron administration before surgery led to an increase in Hb levels, a reduction of RBC use, and an improvement in patient outcome. Only a few studies investigated the use of IV iron in the perioperative setting. These studies recommended the use of perioperative IV iron in cases of severe anemia in orthopedic surgery but not in all types of surgery. Published RCTs in the postoperative setting have shown positive effects of IV iron on Hb levels, length of hospital stay, and transfusion requirements. Some studies demonstrated an increase of Hb of 0.5–1 g/dL over 4 weeks postoperatively, but the clinical relevance and effect of this increase on an improvement of patient's long-term outcomes are uncertain. To summarize, the evidence to use IV iron is strongest in the preoperative setting, while it remains an individual treatment decision to administer IV iron perioperatively or postoperatively.

Prospective Observational Study of Intraoperative Anesthetic Events in District Hospitals in Namibia

BACKGROUND: Access to safe surgery and anesthesia care is grossly inadequate in low- and middle-income countries, with a shortage of anesthesia providers contributing to this crisis. In Namibia, medical officers typically receive no >3 months of informal training in anesthesia. This study sought to determine the prevalence, currently unknown, of intraoperative adverse anesthetic events in this setting. Further, we assessed surgical volume, complications, and mortality outcomes at the district hospital level. METHODS: This was a prospective observational study over 7 months involving 4 district hospitals from geographically separate and diverse areas of Namibia. A standardized protocol was used to record adverse anesthetic events during surgery, surgical volume, and complications including mortality. RESULTS: A total of 737 surgical procedures were performed during the study period. There was a 10% prevalence of adverse anesthetic events intraoperatively. Of these, 70% were related to hypotension and 17% due to hypoxia and/or difficult/failed intubation. Ninety-eight percent of patients were classed as low risk (American Society of Anesthesiologists I or II). Seventy-two percent of the surgical workload was in obstetrics and gynecology, with over half being for urgent obstetrics. Perioperative mortality rate was 1.4/1000, with an overall surgical complication rate of 1.6% and a surgical infection rate of 0.8%. CONCLUSIONS: We found a 10% prevalence of adverse anesthetic events intraoperatively when anesthesia was administered by medical officers with no >3 months of informal training in this low-resource environment. The patients were considered low risk by the medical officers responsible for the anesthesia, yet these events had the potential to lead to patient harm. Accepted for publication October 23, 2017.

Continuous Noninvasive Arterial Pressure Monitoring Using the Vascular Unloading Technique (CNAP System) in Obese Patients During Laparoscopic Bariatric Operations

wk-health-logo.gif

BACKGROUND: Increasing rates of obesity create new challenges for hemodynamic monitoring in the perioperative phase. Continuous monitoring of arterial pressure (AP) is important in severely obese patients who are at particular risk for cardiovascular complications. Innovative technologies for continuous noninvasive AP monitoring are now available. In this study, we aimed to compare continuous noninvasive AP measurements using the vascular unloading technique (CNAP system; CNSystems, Graz, Austria) compared with invasive AP measurements (radial arterial catheter) in severely obese patients during laparoscopic bariatric surgery. METHODS: In 29 severely obese patients (mean body mass index 48.1 kg/m2), we simultaneously recorded noninvasive and invasive AP measurements over a period of 45 minutes and averaged the measurements using 10-second episodes. We compared noninvasive (test method) and invasive (reference method) AP measurements using Bland-Altman analysis and 4-quadrant plot/concordance analysis (2-minute interval). RESULTS: We observed a mean of the differences (±SD, 95% limits of agreement) between the AP values obtained by the CNAP system and the invasively assessed AP values of 7.9 mm Hg (±9.6 mm Hg, −11.2 to 27.0 mm Hg) for mean AP, 4.8 mm Hg (±15.8 mm Hg, −26.5 to 36.0 mm Hg) for systolic AP, and 9.5 mm Hg (±10.3 mm Hg, −10.9 to 29.9 mm Hg) for diastolic AP, respectively. The concordance rate was 97.5% for mean AP, 95.0% for systolic AP, and 96.7% for diastolic AP, respectively. CONCLUSIONS: In the setting of laparoscopic bariatric surgery, continuous noninvasive AP monitoring with the CNAP system showed good trending capabilities compared with continuous invasive AP measurements obtained with a radial arterial catheter. However, absolute CNAP- and arterial catheter–derived AP values were not interchangeable. Accepted for publication September 27, 2017.

Misaligned Feeding May Aggravate Pain by Disruption of Sleep–Awake Rhythm

BACKGROUND: Increasing evidence suggests that patients with eating disorders are more likely to develop chronic pain. A misaligned diet has been reported to disrupt the sleep–awake rhythms. Combined with our previous investigation on circadian pain, we aimed to investigate the role of misaligned diet in the pain sensitivity and the underlying mechanisms. METHODS: Two-month-old C57BL/6J male mice were administered chronic constriction injury (CCI) surgery to establish neuropathic pain models. CCI mice were randomized to scheduled food access throughout the whole day (CCI-free), during the daytime (CCI-misaligned), and at night (CCI-aligned), respectively. The paw withdrawal mechanical threshold, indicating pain behavior, was measured by Von Frey. The gross motor activity pattern indicating the sleep–awake rhythm was monitored by Mini-Mitter. Melatonin (Mel) was administered to ameliorate the sleep–awake rhythm (CCI-free + Mel and CCI-misaligned + Mel). The expressions of circadian pain–related proteins were detected by quantitative polymerase chain reaction and western blot. The primary outcome is the pain threshold and the secondary outcome is the sleep–awake rhythm. RESULTS: Misaligned diet during the peri-CCI surgery period significantly decreased the paw withdrawal mechanical threshold compared with the CCI-free mice (day 14: 0.40 ± 0.09 vs 0.64 ± 0.15; P = .03;) and altered the sleep–awake rhythm. Mel pretreatment alleviated the increased pain (day 14, CCI-misaligned + Mel versus CCI-misaligned: day 14: 0.60 ± 0.13 vs 0.35 ± 0.12; P = .022) and the disrupted sleep–awake rhythm caused by misaligned feeding. The mRNA levels of N-methyl-D-aspartate receptor subtype 2B (NR2B), Ca2+/calmodulin-dependent protein kinase II (CaMKII), and cyclic adenosine monophosphate-response element binding protein (CREB) in the spinal dorsal horn increased in CCI-misaligned mice compared with the CCI-free mice. The phosphor-NR2B, phosphor-CaMKII, and phosphor-CREB also increased in CCI-misaligned mice compared with the CCI-free mice. However, the expressions of NR2B, CaMKII, and CREB were decreased in CCI-misaligned + Mel mice compared to CCI-misaligned mice at both transcriptional and translational levels. CONCLUSIONS: Misaligned diet might aggravate pain sensitivity through the disruption of the sleep–awake cycle, which could be recovered by Mel. NR2B-CaMKII-CREB may participate in the disruption of sleep–awake rhythm–mediated pain aggravation. Accepted for publication November 2, 2017.

Extracorporeal Membrane Oxygenation Appropriateness: An Interdisciplinary Consensus-Based Approach

We describe a quality improvement initiative aimed at achieving interdisciplinary consensus about the appropriate delivery of extracorporeal membrane oxygenation (ECMO). Interdisciplinary rounds were implemented for all patients on ECMO and addressed whether care was consistent with a patient's minimally acceptable outcome, maximally acceptable burden, and relative likelihood of achieving either. The rounding process was associated with decreased days on venoarterial ECMO, from a median of 6 days in 2014 (first quartile [Q1]–third quartile [Q3], 3–10) to 5 days in 2015 (Q1–Q3, 2.5–8) and in 2016 (Q1–Q3, 1–8). Our statistical methods do not allow us to conclude that this change was due to our intervention, and it is possible that the observed decreases would have occurred whether or not the rounding process was implemented.
