Head and Neck Diseases by Alexandros G.Sfakianakis: 02/01/19

Endometrial cancer is the most common gynecological cancer in the developed world, and it is one of the few cancer types that is becoming more prevalent and leading to more deaths in the USA each year. The majority of endometrial tumors are considered to be hormonally driven, where estrogen signaling through estrogen receptor α (ER) acts as an oncogenic signal. The major risk factors and some treatment options for endometrial cancer patients emphasize a key role for estrogen signaling in the disease. Despite the strong connections between estrogen signaling and endometrial cancer, important molecular aspects of ER function remain poorly understood; however, progress is being made in our understanding of estrogen signaling in endometrial cancer. Here, we discuss the evidence for the importance of estrogen signaling in endometrial cancer, details of the endometrial cancer-specific actions of ER, and open questions surrounding estrogen signaling in endometrial cancer.

Optimization of the Surgical Field in Endoscopic Sinus Surgery: an Evidence-Based Approach

Abstract

Purpose of Review

The advent of endoscopic sinus surgery (ESS) has enabled the development of minimally invasive surgical procedures in Rhinology. However, proficiency with ESS techniques can still be hampered by poorly controlled bleeding limiting visibility of the surgical field (VSF). This can lead to increased operating time and, more importantly, increased risk of major and minor complications. To optimize the VSF and mitigate the risk of complications, many strategies have been explored.

Recent Findings

This is a narrative review of the relative risks and benefits of pre- and intra-operative interventions aimed at optimizing intraoperative conditions during ESS. The value of these interventions is determined based on their impact on intraoperative blood loss, time of surgery, and the VSF, and weighed against their adverse event profile.

Summary

This review provides a comprehensive overview of the evidence relating to the safety and efficacy of interventions used to improve intraoperative conditions during ESS.

The impact of chlorophyllin on deoxynivalenol transport across jejunum mucosa explants obtained from adult pigs

Abstract

Regardless of the efforts put into preventing or reducing fungal growth, extensive mycotoxin contamination has been reported in animal feeds. In the case of pigs, one of the mycotoxins of major concern is deoxynivalenol (DON). The use of adsorbents as feed additives represents one of the strategies to control mycotoxins' contamination in feedstuff. Therefore, the aim of the study was to verify the ability of chlorophyllin (CHL) to reduce the absorption rate of DON in swine mucosa explants. Intestine was obtained from routinely slaughtered adult pigs. The mucosa explants were studied by means of Ussing chamber technique. The effect of DON (10 and 30 μg/ml) on mucosa viability and permeability and CHL (100 μg/ml) impact on DON (30 μg/ml) absorption was verified. The results revealed that mucosa explants isolated from adult animals remained unaffected for 90 min in the presence of DON in the lower concentration (10 μg/ml). Mycotoxin in the higher dose (30 μg/ml) increased mucosa permeability (decreased transepithelial electrical resistance value) and enhanced paracellular transport of lucifer yellow and mannitol but did not affect lactate dehydrogenase leakage. The introduction of CHL neither diminished the absorption rate of DON across swine mucosa explants nor prevented the toxic effects of DON on intestine. In conclusion, the results confirm the negative effect of DON on pig jejunum mucosa. However, the toxic effect of DON was observed only when it was used in relatively high doses. A promising adsorbent agent, CHL, failed to reduce the intensity of DON transport across intestine under in vitro conditions.

Impact of type of tooth on outcome of non-surgical root canal treatment

Abstract

Objectives

We assessed the impact of type of tooth on the outcome of root canal treatment (RCT) according to factors potentially weakening the prognosis such as preoperative apical periodontitis (AP) and treatment modality (primary or secondary RCT).

Materials and methods

We scrutinized patient documents including pre- and postoperative radiographs of 640 permanent teeth receiving non-surgical RCT at Helsinki University Clinic in 2008–2011. Of teeth, 44% were molars, 32% premolars, and 24% anterior teeth. Patients' mean age was 51.5 years; 51% were male. AP was present in 60.5% of teeth preoperatively. We used the periapical index (PAI) to assess the radiographs and defined radiographically "healthy" and "healing" cases as successful. Statistical evaluation included chi-squared tests, Fisher's exact tests, t tests, and logistic regression modeling.

Results

The overall success rate (SR) was 84.1%; 88.3% for primary and 75.5% for secondary RCT (p < 0.001). The SRs for anterior teeth, premolars and molars were 85.6%, 88.8%, and 79.7%, respectively. Teeth with and without AP had SRs of 77.3% and 94.5%, respectively (p < 0.001). The RCTs were more likely to succeed in anterior teeth and premolars than in molars (OR 1.7; 95% CI 1.1–2.7) and in females than in males (OR 1.9; 95% CI 1.2–3.1).

Conclusions

Apart from existing AP and retreatment scenario, also, the type of tooth and gender had a significant influence on the outcome of RCT in this study.

Clinical relevance

The prognosis of RCT varies by type of tooth; special attention should be given to RCT of molar teeth.

High incidence of MTHFR, CBS, and MTRR polymorphisms in vitiligo patients. Preliminary report in a retrospective study

OBJECTIVE: Vitiligo is a multifactorial polygenic disorder with a complex pathogenesis. It is related to both genetic and no genetic factors. The role of genetics is currently studied with several analytical approaches, such as genetic linkage, candidate gene association studies, genome-wide association studies (GWAS), deep DNA re-sequencing and gene expression studies. To date, there are no genetic traits directly related to vitiligo pathogenesis.

PATIENTS AND METHODS: 43 cases of vitiligo patients and 30 healthy donors recruited as control, were screened by assaying the biochemical molecules involved in the self-cells cytotoxicity (haptoglobin and homocysteine) and candidate genes involved in the regulatory process of the re-methylation cycles and transsulfuration. Candidate genes and their polymorphisms screened are methylene-tetrahydrofolate-reductase (MTHFR) C677T and A1298C; cystathionine-beta-synthase enzyme (CBS) I278T and Ins68bp; and methionine-synthase-reductase (MTRR) A66G.

RESULTS: A peculiar genetic profile in vitiligo patients are defined: 11.6% of vitiligo patients shown polymorphic variant MTHFR 677TT vs. 3.3% of healthy donor MTHFR 677CC profile (p=0.0017); 14.0% of vitiligo patients shown CBS polymorphic variant 278TT vs. 3.3% of healthy donor 278II profile (p=0.0012); and 11.6% of vitiligo patients shown MTRR 66GG vs. 3.3% of healthy donor MTRR 677AA profile (p>0.0001).

CONCLUSIONS: This is the first study reporting the correlation between the polymorphic status of MTHFR C677T, CBS I278T, and MTRR A66G and vitiligo. The genetic screening of these polymorphisms could be useful for early detection of the inheritance risk factor in a subject carrying relatives with vitiligo. Although these data could suggest a kind of dysregulation, genetically based, of thiols production mechanisms. Based on these results, we have not been able to get hypothesis about the putative pathogenesis of vitiligo, and the precise cause remains unclear.

A pilot prospective study of 577-nm yellow subthreshold micropulse laser treatment with two different power settings for acute central serous chorioretinopathy

Abstract

To compare the efficacy of 50% threshold power with 25% threshold power of 577-nm subthreshold micropulse laser (SMPL) for acute central serous chorioretinopathy (CSC). Prospective, interventional, non-randomized, comparative case series. A total of 54 patients (54 eyes) with acute CSC were enrolled. Twenty-four eyes received 25% threshold power and 30 eyes received 50% threshold power of 577-nm SMPL. Best-corrected visual acuity (BCVA), central macular thickness (CMT), and complete absorption of subretinal fluid (SRF) were evaluated at 1 month and 3 months. The complete absorption rate of SRF in the 50% power group was significantly greater than that in the 25% power group at 1 month (70.0% vs 25.0%, p < 0.001) and at 3 months (83.3% vs 54.2%, p < 0.001). Mean BCVA improved from 0.34 ± 0.20 LogMAR to 0.02 ± 0.13 LogMAR in the 50% power group and from 0.27 ± 0.15 LogMAR to 0.14 ± 0.21 LogMAR in the 25% power group with a significant difference between the two groups after 3 months (p = 0.027). In the 50% power group, the CMT decreased from 491.6 ± 154.8 μm at baseline to 231.3 ± 92.3 μm at 1 month and 228.2 ± 88.1 μm at 3 months, and in the 25% power group, the CMT decreased from 444.9 ± 164.1 to 306.8 ± 102.6 μm at 1 month and 254.5 ± 101.7 μm at 3 months. There was statistical difference of CMT at 1 month (p = 0.009) but no significant difference at 3 months between the two groups (p = 0.232). SMPL with 50% threshold power may be more effective than 25% threshold power for acute CSC.

The photocytotoxicity effect of cationic sulfonated corrole towards lung cancer cells: in vitro and in vivo study

Abstract

Corrole is a kind of new and promising photosensitizer (PS) in cancer photodynamic therapy (PDT). However, the protein molecular mechanism of PDT activity for corrole under light irradiation is still not clear. In this paper, water-soluble cationic sulfonated corrole (1) and its metal complexes (1-Fe, 1-Mn, and 1-Cu) were prepared, and the photodynamic anti-cancer activity against various tumor cells was investigated by MTT assay. The potential molecular mechanism of PDT activity was elucidated by fluorescence microscope, flow cytometry, molecular docking, and western blotting analysis. Besides, the potential PDT anti-tumor effect of 1 in vivo was assessed in human tumor xenografts in mice. Quantitative analysis revealed that 1's phototoxicity triggered a significant generation of reactive oxygen species, causing disruption of mitochondrial membrane potential. The results of western blotting (WB) assay shown in 1's phototoxicity could induce cell apoptosis via ROS-mediated mitochondrial caspase apoptosis pathway, in which SIRT1 protein degradation played a key role. PTD activity in vivo shown in 1 could significantly reduce the growth of A549 xenografted tumor, without obvious loss of mice body weight. We clearly found that cationic sulfonated corrole is a potential candidate of PS in vitro and in vivo. The phototoxicity of 1 could induce A549 cell apoptosis by inducing ROS production increase, further to activate the mitochondrial apoptosis pathway. We concluded that SIRT1 protein is a more appropriate target in this progress.

Neoadjuvant Management of Early Breast Cancer: A Clinical and Investigational Position Statement

AbstractBackground.Neoadjuvant treatment is increasingly one of the preferred therapeutic options for early breast cancer and may have some unique outcomes, such as identifying predictive and prognostic factors of response or increasing the knowledge of individual tumor biology.Design.A panel of experts from different specialties reviewed published clinical studies on the neoadjuvant management of breast cancer. Recommendations were made that emphasized the clinical multidisciplinary management and the investigational leverage in early breast cancer.Results.Neoadjuvant therapy has equivalent efficacy to adjuvant therapy, and it has some additional benefits that include increasing breast conservation, assessing tumor response, establishing prognosis based on the pathological response, and providing a "second opportunity" for nonresponding patients. Achieving pathological complete remission because of neoadjuvant therapy has been correlated with long‐term clinical benefit, particularly in HER2‐positive and triple‐negative breast cancer. In addition, the neoadjuvant setting is a powerful model for the development of new drugs and the identification of prognostic markers. Finally, neoadjuvant therapy has proven to be cost‐effective by reducing nondrug costs, avoiding radical surgery, and reducing hospital stays when compared with other treatment approaches.Conclusion.Neoadjuvant therapy has clinical benefits in early breast cancer and provides in vivo information of individual breast cancer biology while allowing the investigation of new treatment approaches. Access to neoadjuvant therapy should be an option available to all patients with breast cancer through multidisciplinary tumor management.Implications for Practice.Neoadjuvant treatment should be strongly considered as a therapeutic option for localized breast cancer and is a powerful tool for understanding breast cancer biology and investigating new treatment approaches.

A Pilot Study of Vinorelbine Safety and Pharmacokinetics in Patients with Varying Degrees of Liver Dysfunction

AbstractBackground.Vinorelbine has demonstrated anticancer activity and is primarily metabolized in the liver. This single‐institution, phase I pilot study describes the safety and pharmacokinetics of vinorelbine in patients with varying degrees of hepatic impairment.Materials and Methods.Patients with treatment‐refractory solid tumors were enrolled into treatment arms based on vinorelbine dose (weekly infusions of 7.5–30 mg/m2) and liver function (normal liver function, mild, moderate, or severe liver dysfunction). Vinorelbine pharmacokinetics were evaluated to describe its relationship with liver function. Indocyanine green (ICG) clearance was assessed for correlation with pharmacokinetics.Results.Forty‐seven patients were enrolled, and a total of 108 grade 3–4 treatment‐related adverse events (AEs) occurred. Of these, grade 3–4 myelosuppression was the most common (34.3%). Thirty‐three (30.6%), 22 (20.4%), and 9 (8.3%) grade 3–4 AEs were observed in the vinorelbine 20 mg/m2/severe, 15 mg/m2/moderate, and 7.5 mg/m2/severe liver dysfunction groups, respectively, with the majority being nonhematologic toxicities. ICG clearance decreased as liver function worsened. Vinorelbine pharmacokinetics were not correlated with ICG elimination or the degree of liver dysfunction.Conclusion.For patients with severe liver dysfunction (bilirubin >3.0 mg/dL), vinorelbine doses ≥7.5 mg/m2 are poorly tolerated. The high incidence of grade 3–4 AEs with 15 mg/m2 vinorelbine in moderate liver dysfunction (bilirubin 1.5–3.0 mg/dL) raises concerns for its safety in this population. Vinorelbine pharmacokinetics are not affected by liver dysfunction; however, levels of the active metabolite 4‐O‐deacetylvinorelbine were not measured and may be higher in patients with liver dysfunction if its elimination is impacted by liver impairment to a greater degree than the parent drug.Implications for Practice.Vinorelbine remains widely prescribed in advanced malignancies and is under development in immunotherapy combinations. Given vinorelbine is primarily hepatically metabolized, understanding its safety and pharmacokinetics in liver dysfunction remains paramount. In this phase I pilot study, weekly vinorelbine at doses ≥7.5 mg/m2 is poorly tolerated in those with severe liver dysfunction. Furthermore, a high incidence of grade 3–4 toxicities was observed with vinorelbine at 15 mg/m2 in those with moderate liver dysfunction. Vinorelbine pharmacokinetics do not appear affected by degree of liver dysfunction. Further evaluation of levels of the free drug and active metabolites in relationship to liver function are warranted.

A Cost‐Effectiveness Analysis of Nivolumab and Ipilimumab Versus Sunitinib in First‐Line Intermediate‐ to Poor‐Risk Advanced Renal Cell Carcinoma

AbstractBackground.The treatment paradigm of advanced renal cell carcinoma (RCC) has changed rapidly in recent years. In first‐line treatment of intermediate‐ to poor‐risk patients, the CheckMate 214 study demonstrated a significant survival advantage for nivolumab and ipilimumab versus sunitinib. The high cost of combined immune‐modulating agents warrants an understanding of the combination's value by considering both efficacy and cost. The objective of this study was to estimate the cost‐effectiveness of nivolumab and ipilimumab compared with sunitinib for first‐line treatment of intermediate‐ to poor‐risk advanced RCC from the U.S. payer perspective.Materials and Methods.A Markov model was developed to compare the costs and effectiveness of nivolumab and ipilimumab with those of sunitinib in the first‐line treatment of intermediate‐ to poor‐risk advanced RCC. Health outcomes were measured in life‐years and quality‐adjusted life‐years (QALYs). Drug costs were based on Medicare reimbursement rates in 2017. We extrapolated survival beyond the trial closure using Weibull distribution. Model robustness was addressed in univariable and probabilistic sensitivity analyses.Results.The total mean cost per‐patient of nivolumab and ipilimumab versus sunitinib was $292,308 and $169,287, respectfully. Nivolumab and ipilimumab generated a gain of 0.978 QALYs over sunitinib. The incremental cost‐effectiveness ratio (ICER) for nivolumab and ipilimumab was $125,739/QALY versus sunitinib.Conclusion.Our analysis established that the base case ICER in the model for nivolumab and ipilimumab versus sunitinib is below what some would consider the upper limit of the theoretical willingness‐to‐pay threshold in the U.S. ($150,000/QALY) and is thus estimated to be cost‐effective.Implications for Practice.This article assessed the cost‐effectiveness of nivolumab and ipilimumab versus sunitinib for treatment of patients with intermediate‐ to poor‐risk metastatic kidney cancer, from the U.S. payer perspective. It would cost $125,739 to gain 1 quality‐adjusted life‐year with nivolumab and ipilimumab versus sunitinib in these patients.

Changes in the Use of Comprehensive Geriatric Assessment in Clinical Trials for Older Patients with Cancer over Time

AbstractBackground.The objective of this study was to describe the implementation of comprehensive geriatric assessment (CGA) in clinical trials dedicated to older patients before and after the creation of the International Society of Geriatric Oncology in the early 2000s.Subjects, Materials, and Methods.All phase I, II, and III trials dedicated to the treatment of cancer among older patients published between 2001 and 2004 and between 2011 and 2014 were reviewed. We considered that a CGA was performed when the authors indicated an intention to do so in the Methods section of the article. We collected each geriatric domain assessed using a validated tool even in the absence of a clear CGA, including nutritional, functional, cognitive, and psychological status, comorbidity, comedication, overmedication, social status and support, and geriatric syndromes.Results.A total of 260 clinical trials dedicated to older patients were identified over the two time periods: 27 phase I, 193 phase II, and 40 phase III trials. CGA was used in 9% and 8% of phase II and III trials, respectively; it was never used in phase I trials. Performance status was reported in 67%, 79%, and 75% of phase I, II, and III trials, respectively. Functional assessment was reported in 4%, 11%, and 13% of phase I, II, and III trials, respectively. Between the two time periods, use of CGA increased from 1% to 11% (p = .0051) and assessment of functional status increased from 3% to 14% (p = .0094).Conclusion.The use of CGA in trials dedicated to older patients increased significantly but remained insufficient.Implications for Practice.This article identifies the areas in which research efforts should be focused in order to offer physicians well‐addressed clinical trials with results that can be extrapolated to daily practice.

Laryngo-Rhino-Otol
DOI: 10.1055/a-0834-6147

Hintergrund Die Sialendoskopie ist ein minimal-invasives Verfahren zur Diagnostik und Therapie von Erkrankungen des Speicheldrüsengangsystems. Sie kann in ITN und in LA durchgeführt werden. Vor diesem Hintergrund ist die postoperative Schmerzsituation interessant, über deren Ausmaß aktuell jedoch wenig bekannt ist. Daher wurden in dieser Studie die postoperativen Schmerzen nach Sialendoskopie in LA und ihr Schmerzmanagement in einer quantitativen Untersuchung erfasst und analysiert. Material und Methoden Es wurden 103 Patienten in die retrospektive Studie eingeschlossen, bei denen im Zeitraum von 2013 bis 2015 eine Sialendoskopie der Glandula parotis oder der Glandula submanibularis in Lokalanästhesie durchgeführt wurde. Analysiert wurden die postoperativen Schmerzen in Ruhe und bei Belastung am Operationstag, sowie am ersten und zweiten postoperativen Tag. Die Schmerzen wurden anhand einer numerischen Rating Skala (NRS 0–10) erfasst, welche im Rahmen des QUIPS-Projektes (Qualitätsverbesserung in der postoperativen Schmerztherapie) verwendet wird. Ergebnisse Am Operationstag betrug der Schmerz in Ruhe 0,9 ± 1,9 und bei Belastung 0,7 ± 1,4. Am ersten postoperativen Tag wurden Schmerzen von 1,2 ± 1,8 in Ruhe und 0,9 ± 1,9 bei Belastung festgestellt. Am zweiten postoperativen Tag zeigte sich eine Reduktion der Schmerzen auf 0,75 ± 1,6 in Ruhe und 0,73 ± 1,5 bei Belastung. Insgesamt wurden Metamizol (Novalgin®) und Ibuprofen als häufigste postoperative Analgetika eingesetzt. Am Operationstag erhielten 37,9 % der Patienten Schmerzmittel, am ersten postoperativen Tag 26,2 % der Patienten und am zweiten postoperativen Tag 12,6 % der Patienten. Schlussfolgerung Sialendoskopien der Glandula submandibularis und parotis sind mit moderaten postoperativen Schmerzen verbunden, welche sich gut mit Nicht-Opioiden behandeln lassen.

Does information and communication technologies improve environmental quality in the era of globalization? An empirical analysis

Abstract

This study intends to examine the impact of ICTs (i.e., internet usage and mobile cellular subscriptions), globalization, electricity consumption, financial development, and economic growth on environmental quality by using 1994–2014 panel data of BRICS economies. This study employed a second-generation panel unit root test accounting for the presence of cross-sectional dependence and indicated that carbon dioxide emissions, electricity consumption, financial development, internet usage, mobile usage, globalization, and economic growth have integration of order one. The results from Westerlund panel co-integration test confirms that the variables are co-integrated and revealed that ICT-finance-globalization-electricity-GDP-CO₂ nexus has long-run equilibrium relationship. The results from dynamic seemingly unrelated regression (DSUR) indicate that internet usage and mobile cellular subscriptions (ICTs) have significant, adverse impact on carbon dioxide emissions. To put it simply, ICT positively contributes towards environmental quality. Similarly, economic growth also has an adverse effect on carbon dioxide emissions. On the other hand, electricity consumption, globalization, and financial development have a significant positive effect on carbon emissions. In addition, Granger causality test results show the presence of a bidirectional causal relationship between internet usage and environmental quality, financial development and electricity consumption, ICT and financial development, mobile cellular subscription and globalization, economic growth and environmental quality, and internet usage and economic growth. A unidirectional causal link is detected running from mobile cellular subscriptions towards environmental quality, ICT towards electricity consumption, financial development towards environmental quality, globalization towards environmental quality, and globalization towards economic growth. Moreover, time series analysis has also been done in this study to analyze the findings for each of BRICS countries which are directed towards important policy implications. For instance, ICT policy can play an integral part in improving environmental quality policy.

Experimental investigation of diesel engine performance fuelled with the blends of Jatropha curcas , ethanol, and diesel

Abstract

Nonrenewable fossil fuels show increased demand and with fossil fuels at a rapid depleting stage, there seems to be an increase in requirement for alternative fuels too. Biofuels and blended fossil fuels are one of a kind. Nonedible jatropha (Jatropha curcas) oil-based methyl ester was produced and mixed with ethanol and blended with conventional diesel in various compositions. Jatropha biodiesel is used because of its great blending capacity with diesel. Sodium hydroxide is used as a catalyst which allows miscibility between ethanol and diesel. In present epoch, the paucity of fossil fuels and its adverse impact have driven researchers to focus on alternative fuels. Biodiesel is one of the most favorable and promising alternatives in the application of automobiles, boilers, gas turbines, etc. This study targets at finding the engine performance and emission characteristics under various load conditions on Kirloskar single-cylinder VCR research engine by blending both jatropha biodiesel and ethanol with base diesel at various compositions. Both jatropha biodiesel and ethanol have high calorific value which is a most important factor for engine power production. The performance analysis showed that the biodiesel blend of 98% diesel with 1.5% jatropha biodiesel and 0.5% (D98J1.5E0.5) of ethanol had a significant improvement in the engine performance than the conventional diesel.

Follicular mucinosis in patients with hematologic malignancies other than mycosis fungoides: A clinicopathologic study

Follicular mucinosis in association with systemic hematologic disorders other than mycosis fungoides is poorly characterized. Clinicopathological features of follicular mucinosis in the setting of hematopoietic stem cell transplantation and diverse systemic hematologic malignancies differ from mycosis fungoides-associated cases and follicular mucinosis is not necessarily a precursor to cutaneous T-cell lymphoma.

Inhibition of Histone Methyltransferase G9a Attenuates Noise-Induced Cochlear Synaptopathy and Hearing Loss

ABSTRACT

Posttranslational modification of histones alters their interaction with DNA and nuclear proteins, influencing gene expression and cell fate. In this study, we investigated the effect of G9a (KMT1C, EHMT2), a major histone lysine methyltransferase encoded by the human EHMT2 gene and responsible for histone H3 lysine 9 dimethylation (H3K9me2) on noise-induced permanent hearing loss (NIHL) in adult CBA/J mice. The conditions of noise exposure used in this study led to losses of cochlear synapses and outer hair cells (OHCs) and permanent auditory threshold shifts. Inhibition of G9a with its specific inhibitor BIX 01294 or with siRNA significantly attenuated these pathological features. Treatment with BIX 01294 also prevented the noise-induced decrease of KCNQ4 immunolabeling in OHCs. Additionally, G9a was increased in cochlear cells, including both outer and inner sensory hair cells, some spiral ganglion neurons (SGNs), and marginal cells, 1 h after the completion of the noise exposure. Also subsequent to noise exposure, immunoreactivity for H3K9me2 appeared in some nuclei of OHCs following a high-to-low frequency gradient with more labeled OHCs in the 45-kHz than the 32-kHz region, as well as in the marginal cells and in some SGNs of the basal turn. These findings suggest that epigenetic modifications of H3K9me2 are involved in NIHL and that pharmacological targeting of G9a may offer a strategy for protection against cochlear synaptopathy and NIHL.

Synthesis and characterization of magnetic Fe 3 O 4 @CaSiO 3 composites and evaluation of their adsorption characteristics for heavy metal ions

Abstract

A two-component material (Fe₃O₄@CaSiO₃) with an Fe₃O₄ magnetite core and layered porous CaSiO₃ shell from calcium nitrate and sodium silicate was synthesized by precipitation. The structure, morphology, magnetic properties, and composition of the Fe₃O₄@CaSiO₃ composite were characterized in detail, and its adsorption performance, adsorption kinetics, and recyclability for Cu²⁺, Ni²⁺, and Cr³⁺ adsorption were studied. The Fe₃O₄@CaSiO₃ composite has a 2D core–layer architecture with a cotton-like morphology, specific surface area of 41.56 m²/g, pore size of 16 nm, and pore volume of 0.25 cm³/g. The measured magnetization saturation values of the magnetic composite were 57.1 emu/g. Data of the adsorption of Cu²⁺, Ni²⁺, and Cr³⁺ by Fe₃O₄@CaSiO₃ fitted the Redlich–Peterson and pseudo-second-order models well, and all adsorption processes reached equilibrium within 150 min. The maximum adsorption capacities of Fe₃O₄@CaSiO₃ toward Cu²⁺, Ni²⁺, and Cr³⁺ were 427.10, 391.59, and 371.39 mg/g at an initial concentration of 225 mg/L and a temperature of 293 K according to the fitted curve with the Redlich–Peterson model, respectively. All adsorption were spontaneous endothermic processes featuring an entropy increase, including physisorption, chemisorption, and ion exchange; among these process, chemisorption was the primary mechanism. Fe₃O₄@CaSiO₃ exhibited excellent adsorption, regeneration, and magnetic separation performance, thereby demonstrating its potential applicability to removing heavy metal ions.

Preparation of various thiol-functionalized carbon-based materials for enhanced removal of mercury from aqueous solution

Abstract

In this work, biochar (BC), activated carbon (AC), and graphene oxide (GO) were thiol-functionalized using 3-mercaptopropyltrimethoxysilane (3-MPTS) (named as BCS, ACS, and GOS, respectively). BCS, ACS, and GOS were synthesized mainly via the interaction between hydrolyzed 3-MPTS and surface oxygen-containing functional groups (e.g., –OH, O–C=O, and C=O) and π-π interaction. The materials before and after modification were characterized and tested for mercury removal, including sorption kinetics and isotherms, the effects of adsorbent dosage, initial pH, and ionic strength. Pseudo-second-order sorption kinetic model (R² = 0.992~1.000) and Langmuir sorption isotherm model (R² = 0.964~0.998) fitted well with the sorption data of mercury. GOS had the most –SH groups with the largest adsorption capacity for Hg²⁺ and CH₃Hg⁺ (449.6 and 127.5 mg/g), followed by ACS (235.7 and 86.7 mg/g) and BCS (175.6 and 30.3 mg/g), which were much larger than GO (96.7 and 4.9 mg/g), AC (81.1 and 24.6 mg/g), and BC (95.6 and 9.4 mg/g). GOS and ACS showed stable mercury adsorption properties at a wide pH range (2~9) and ionic strength (0.01~0.1 mol/L). Mercury maybe removed by ligand exchange, surface complexation, and electrostatic attraction.

The application of forward osmosis for simulated surface water treatment by using trisodium citrate as draw solute

Abstract

In this study, trisodium citrate was used as draw solute in forward osmosis (FO) due to its biodegradability and easy reuse after FO dilution. The effect of operating conditions on FO performance was investigated. The study focused on the long-term flux performance and membrane fouling when surface water was used as feed solution. A water flux of 9.8 LMH was observed using 0.5 M trisodium citrate as draw solution in PRO mode. In the long-term FO process, trisodium citrate showed a slight decrease in total flux loss (13.06%) after 20 h of operation. The membrane fouling was significantly reduced after a two-step physical cleaning. A considerable flux recovery (> 95%) of the fouled membrane was finally obtained. Therefore, this study proves the superiority of trisodium citrate as draw solution and paves a new way in applying FO directly for surface water reclamation.

In vivo comparison of the proangiogenic properties of chlordecone and three of its dechlorinated derivatives formed by in situ chemical reduction

Abstract

In situ chemical reduction (ISCR) has been identified as a possible way for the remediation of soils contaminated by chlordecone (CLD). Evidences provided by the literature indicate an association between the development of prostate cancer and CLD exposure (Multigner et al. 2010). In a previous in vitro study, we demonstrated that the two main dechlorinated CLD derivatives formed by ISCR, CLD-1Cl, and CLD-3Cl have lower cytotoxicity and proangiogenic properties than CLD itself (Legeay et al. 2017). By contrast, nothing is known on the in vivo proangiogenic effect of these dechlorinated derivatives. Based on in vitro data, the aims of this study were therefore to evaluate the in vivo influence of CLD and three of its dechlorinated metabolites in the control of neovascularization in a mice model of prostate cancer. The proangiogenic effect of CLD and three of its dechlorinated derivatives, CLD-1Cl, CLD-3Cl, and CLD-4Cl, was evaluated on a murine model of human prostate tumor (PC-3) treated, at two exposure levels: 33 μg/kg and 1.7 μg/kg respectively reflecting acute and chronic toxic exposure in human. The results of serum measurements show that, for the same ingested dose, the three metabolite concentrations were significantly lower than that of CLD. Dechlorination of CLD lead therefore to molecules that are biologically absorbed or metabolized, or both, faster than the parent molecule. Prostate tumor growth was lower in the groups treated by the three metabolites compared to the one treated by CLD. The vascularization measured on the tumor sections was inversely proportional to the rate of dechlorination, the treatment with CLD-4Cl showing no difference with control animals treated with only the vehicle oil used for all substances tested. We can therefore conclude that the proangiogenic effect of CLD is significantly decreased following the ISCR-resulting dechlorination. Further investigations are needed to elucidate the molecular mechanisms by which dechlorination of CLD reduces proangiogenic effects in prostate tumor.

Biocompatibility and biodistribution of surface-modified yttrium oxide nanoparticles for potential theranostic applications

Abstract

The surface of ultrafine yttrium oxide nanoparticles (NPs) with mean size of 7–8 nm was modified with a functional polymer layer to improve their dispersion and impart fluorescent properties for imaging purposes. Surface functionalization was achieved by silanization of yttrium oxide NPs with 3-trimethoxysilylpropyl methacrylate followed by grafting of a co-polymer made of acrylic acid (AA) and ethylene glycol methacrylate phosphate (EGMP). The polymer shell decreases the surface energy of NPs, enhances their polarity, and, as a result, improves their colloidal stability. The synthesized NPs are capable of scavenging free radicals and for this reason have therapeutic potential that warrants further investigations. Furthermore, these stabilized core–shell NPs showed a very low cytotoxicity, confirming that the polymer shell sensibly improves the biocompatibility of bare yttrium oxide NPs, which are otherwise toxic on their own. Poly-EGMP yttrium NPs proved to be safe up to 0.1 mg/g body weight in 1 month old Sprague–Dawley rats, showing also the ability to cross the blood–brain barrier short time after tail injection. The surface modification of yttrium NPs here described allows these NPs to be potentially used in theranostics to reduce neurodegenerative damage due to the heat stress.

Implications and Future Perspectives of AGEs in PCOS Pathophysiology

Publication date: Available online 1 February 2019

Source: Trends in Endocrinology & Metabolism

Author(s): Zaher Merhi, Eleni A. Kandaraki, Evanthia Diamanti-Kandarakis

Human, animal, and in vitro studies provide evidence that advanced glycation end-products (AGEs) may contribute to the pathogenesis of polycystic ovary syndrome (PCOS) and its metabolic and reproductive consequences. AGEs are able to induce, via activation of key intracellular signaling pathways, the generation of oxidative stress and proinflammatory cytokines, thus contributing to the adverse health impact of PCOS. This review presents the implications of AGEs in several disease pathophysiologies, including PCOS, as well as the cellular and systemic effects of AGEs on insulin resistance (IR), hyperandrogenemia, endoplasmic reticulum (ER) stress, hypoxia, and ovarian function. The gaps in our knowledge will serve as launching pad for future developments ranging from dietary and lifestyle changes to pharmaceutical interventions aiming at potential applications in women with PCOS.

Author(s): Peng Jia, Hong Xue, Li Yin, Alfred Stein, Minqi Wang, Youfa Wang

Geographic Information Systems (GIS), Global Positioning Systems (GPS), and remote sensing (RS) are revolutionizing obesity-related research. The primary applications of GIS have included visualizing obesity outcomes and risk factors, constructing obesogenic environmental indicators, and detecting geographical patterns of obesity prevalence and obesogenic environmental features. GPS was mainly used to delineate individual activity space and combined with other devices to measure obesogenic behaviors. RS has been understated for its role as important sources of data about natural and built environments. These spatial technologies, collectively called the 3S technologies, will be useful in measuring more facets of obesogenic environments and individual environmental exposure at finer levels and studying obesity etiology and interventions.

Environmental risk appraisement of disinfection by-products (DBPs) in plant model system: Allium cepa

Abstract

The organic toxicants formed in chlorinated water cause potential harm to human beings, and it is extensively concentrated all over the world. Various disinfection by-products (DBPs) occur in chlorinated water are genotoxic and carcinogenic. The toxicity is major concern for chlorinated DBPs which has been present more in potable water. The purpose of the work was to evaluate genotoxic properties of DBPs in Allium cepa as a plant model system. The chromosomal aberration and DNA laddering assays were performed to examine the genotoxic effect of trichloroacetic acid (TCAA), trichloromethane (TCM), and tribromomethane (TBM) in a plant system with distinct concentrations, using ethyl methanesulfonate (EMS) as positive control and tap water as negative control. In Allium cepa root growth inhibition test, the inhibition was concentration dependent, and EC₅₀ values for trichloroacetic acid (TCAA), trichloromethane (TCM), and tribromomethane (TBM) were 100 mg/L, 160 mg/L, and 120 mg/L respectively. In the chromosome aberration assay, root tip cells were investigated after 120 h exposure. The bridge formation, sticky chromosomes, vagrant chromosomes, fragmented chromosome, c-anaphase, and multipolarity chromosomal aberrations were seen in anaphase–telophase cells. It was noticed that with enhanced concentrations of DBPs, the total chromosomal aberrations were more frequent. The DNA damage was analyzed in roots of Allium cepa exposed with DBPs (TCAA, TCM, TBM) by DNA laddering. The biochemical assays such as lipid peroxidation, H₂O₂ content, ascorbate peroxidase, guaiacol peroxidase, and catalase were concentration dependent. The DNA interaction studies were performed to examine binding mode of TCAA, TCM, and TBM with DNAs. The DNA interaction was evaluated by spectrophotometric and spectrofluorometric studies which revealed that TCAA, TCM, and TBM might interact with Calf thymus DNA (CT- DNA) by non-traditional intercalation manner.

Extremity nevus count is an independent risk factor for basal cell carcinoma and melanoma, but not squamous cell carcinoma

Publication date: Available online 31 January 2019

Source: Journal of the American Academy of Dermatology

Author(s): Erin X. Wei, Xin Li, Hongmei Nan

Background

The presence of nevi portends an increased risk for melanoma.

Objective

We sought to examine the association between extremity nevus count and the risk of melanoma and keratinocyte cancers.

Methods

We evaluated prospective cohorts of 176,317 women (the Nurses' Health Study, 1986-2012 and the Nurses' Health Study 2, 1989-2013) and 32,383 men (Health Professionals Follow-up Study, 1986-2012). Information on nevus count (none, 1-5, 6-14, ≥15) on the extremity was collected at baseline.

Results

There were 1704 incident cases of melanoma, 2296 incident cases of squamous cell carcinoma, and 30,457 incident cases of basal cell carcinoma, with a total of 4,655,043 person-years for melanoma and 4,267,708 person-years for keratinocyte cancers. The presence of an extremity nevus was associated with an increased risk of melanoma in all anatomic areas and increased risk of basal cell carcinoma (BCC). Individuals with ≥15 nevi had the highest risk of melanoma and BCC compared to those without any extremity nevi (melanoma hazard ratio 2.79 [95% confidence interval 2.04-3.83]; BCC HR 1.40 [95% confidence interval 1.32-1.49]). No significant association was observed for squamous cell carcinoma.

Limitations

Limitations of our study included self-reported nevus count and detection bias.

Conclusions

Extremity nevus count is a helpful clinical marker in risk-stratifying individuals for BCC and melanoma on all body sites.

Craniopharyngiomas are rare but challenging tumors of the ventral skull base affecting primarily pediatric patients. In select cases, the endoscopic endonasal approach represents an appropriate surgical option when tumor resection is favored. However, nuances of the pediatric nasal corridor must be carefully considered to optimize both tumor resection and skull base reconstruction. Here we review pertinent developmental details, options for creation of an optimal endonasal corridor, principles of tumor resection, and techniques for reconstruction. Considerations for intraoperative and postoperative patient care are also reviewed.

Characterizing Pediatric Inpatient Sleep Duration and Disruptions

via Sleep Medicine

Publication date: Available online 31 January 2019

Source: Sleep Medicine

Author(s): Amarachi I. Erondu, Nicola M. Orlov, Leah B. Peirce, Samantha L. Anderson, Michael Chamberlain, Kelsey Hopkins, Christopher Lyttle, David Gozal, Vineet M. Arora

Abstract

Objective

To contextualize inpatient sleep duration and disruptions in a general pediatric hospital ward by comparing in-hospital and at-home sleep durations to recommended guidelines and objectively measure nighttime room entries.

Methods

Caregivers of patients 4 weeks - 18 years of age reported patient sleep duration and disruptions in anonymous surveys. Average at-home and in-hospital sleep durations were compared to National Sleep Foundation recommendations. Objective nighttime traffic was evaluated as the average number of room entries between 11:00pm and 7:00am using GOJO hand-hygiene room entry data.

Results

Among 246 patients, patients slept less in the hospital than at home with newborn and infant cohorts experiencing 7- and 4-hour sleep deficits respectively (Newborn: 787 ± 318 min at home vs. 354 ± 211 min in hospital, p<0.001; Infants: 530 ± 115 min at home vs. 412 ± 152 min in hospital, p<0.01). Newborn children also experienced >2 hour sleep deficits at home when compared to NSF recommendations (Newborns: 787 ± 318 min at home vs. 930 min recommended, p< 0.05). Objective nighttime traffic measures revealed that hospitalized children experienced 10 room entries/night (10 ± 5.9 entries). Nighttime traffic was significantly correlated with caregiver-reported nighttime awakenings (Spearman Rank Correlation Coefficient: 0.58, p=.04).

Conclusion

Hospitalization is a missed opportunity to improve sleep both in the hospital and at home.

Insomnia Treatment Response as a Function of Objectively Measured Sleep Duration

via Sleep Medicine

Publication date: Available online 31 January 2019

Source: Sleep Medicine

Author(s): Amélie Rochefort, Denise C. Jarrin, Lynda Bélanger, Hans Ivers, Charles M. Morin

Abstract

Objectives

To examine the potential moderating effect of objectively measured sleep duration at baseline on the response to cognitive behavioral therapy for insomnia (CBT-I), administered singly or combined with medication (CBT-I+Med).

Methods

Based on the average PSG-derived sleep duration across two baseline nights and the type of treatment received, 159 adults with insomnia (50.3 ± 10.1 years; 61.0% women) were classified into one of four groups: participants with short sleep duration (i.e., ≤ 6h) treated with CBT-I (n = 26) or CBT-I+Med (n = 25), and participants with normal sleep duration (i.e., > 6h) treated with CBT-I (n = 54) or CBT-I+Med (n = 54). Primary outcome measures were sleep/wake parameters derived from a sleep diary and insomnia severity and secondary outcomes were beliefs about sleep, fatigue, depression and anxiety.

Results

Patients with both short and normal sleep durations at baseline improved significantly on most sleep continuity parameters with CBT-I administered singly or combined with medication. Irrespective of treatment received, participants with short sleep duration also showed significantly greater improvements in subjective sleep (i.e., reduced wake after sleep onset, increased sleep efficiency) relative to those with normal sleep duration. Conversely, participants with normal sleep duration showed greater improvements on some measures of daytime functioning and sleep satisfaction.

Conclusions

There was no moderating effect of baseline sleep duration on treatment response to cognitive behavioral therapy. Despite some marginal differential treatment response on selected daytime functioning outcomes, the benefits from CBT-I were not significantly different as a function of short or normal sleep duration at baseline. Further prospective investigation of insomnia phenotypes taking into account other variables than sleep duration is warranted in order to develop more targeted insomnia therapies.

Association of change in physical activity and sleep complaints: Results from a 6-year longitudinal study with Swedish health care workers

via Sleep Medicine

Publication date: Available online 31 January 2019

Source: Sleep Medicine

Author(s): Markus Gerber, Mats Börjesson, Ingibjörg H. Jonsdottir, Magnus Lindwall

Abstract

Objective

To increase our understanding of patterns of change in physical activity and sleep complaints and to test whether intra-individual changes in physical activity are correlated with intra-individual changes in sleep complaints across four measurement time-points over six years, adopting both a between-person and within-person perspective.

Methods

Data from a longitudinal cohort study were used in this research. At baseline, 3187 participants took part in the study (86% women, Mage=46.9 years). The response rate was 84% (n=3136) after two years, 60% (n=2232) after four years, and 40% (n=1498) after six years. Physical activity was assessed with the [51] widely used 4-level physical activity scale (SGPALS), and sleep complaints, with three items from the Karolinska Sleep Questionnaire (KSQ). Patterns and correlations of change between physical activity and sleep complaints were examined with latent growth curve modeling.

Results

Changes in physical activity were associated with changes in sleep complaints across the six years. More specifically, significant associations occurred between baseline levels, correlated (between-person) change, and coupled (within-person change). These associations indicate that higher physical activity levels are not only cross-sectionally linked with fewer sleep complaints, but that increases in physical activity over time (either in comparison to others or to oneself) are paralleled by decreases in sleep complaints.

Conclusions

Given that changes in physical activity and sleep are correlated, our findings indicate that it is both worthwhile to initiate more physically active lifestyles in physically inactive individuals and to ensure that those who are already physically active maintain their physical activity levels over longer periods.

Continuous positive airway pressure alters brain microstructure and perfusion patterns in patients with obstructive sleep apnea

via Sleep Medicine

Publication date: Available online 31 January 2019

Source: Sleep Medicine

Author(s): Hillel S. Maresky, Isaac Shpirer, Miriam M. Klar, Max Levitt, Efrat Sasson, Sigal Tal

Abstract

Objectives

To assess the effects of continuous positive airway pressure (CPAP) treatment on brain structure and function in patients with obstructive sleep apnea (OSA).

Methods

A prospective study of seven OSA patients recruited from the sleep center at our institution was carried out. Patients were treated with 6 weeks of CPAP treatment. Pre-treatment and post-treatment magnetic resonance imaging (MRI) perfusion scans were obtained and compared to assess for treatment-induced changes. Microstructural changes were quantified using functional anistrophy (FA) and mean diffusivity (MD), and brain perfusion was quantified using cerebral blood flow (CBF) and cerebral blood volume (CBV).

Results

Of the seven patients included the in study, six (85.7%) were male, and the mean age of the study population was 51 years (standard deviation = 13.14). Increased FA and decreased MD were found in the hippocampus, temporal lobes, fusiform gyrus, and occipital lobes. Decreased FA and increased MD were found in frontal regions for all patients (p<0.05). Increased CBF and CBV were also observed following treatment (p<0.05).

Conclusion

In addition to symptom resolution, CPAP treatment may allow for healing of OSA-induced brain damage as seen by restoration of brain structure and perfusion.

Postpartum fatigue, daytime sleepiness, and psychomotor vigilance are modifiable through a brief residential early parenting program

via Sleep Medicine

Publication date: Available online 31 January 2019

Source: Sleep Medicine

Author(s): Nathan Wilson, Karen Wynter, Clare Anderson, Shantha.M.W. Rajaratnam, Jane Fisher, Bei Bei

Abstract

Objective

/Background: In the months after childbirth, women are vulnerable to sleep disturbances and sleep-related deficits in functioning, such as fatigue, daytime sleepiness, and attentional lapses. Currently there is limited evidence that these deficits are modifiable. Using both self-report and objective measures, this study examined changes in sleep-related daytime functioning among women attending a residential early parenting program for assistance with unsettled infant behavior and mild to moderate postpartum distress.

Methods

Participants were 78 women (age M=34.16, SD=4.16 years) attending a 5-day program with their infants (age M=8.67, SD=4.82 months). Sleep was assessed via self-report. Sleep-related daytime functioning was operationalized as fatigue, sleepiness, and sustained attention, and measured using validated questionnaires (all women) and the 10-min visual Psychomotor Vigilance Test (PVT; subgroup of 47 women). All measures were administered on both admission (baseline) and discharge.

Results

On admission, participants reported elevated sleep disturbance (94%), fatigue (91%), as well as trait (54%) and state (67%) sleepiness. From admission to discharge, there were medium effect size reductions in fatigue and sleepiness, and large effect size improvements in sleep quality related domains such as increased sleep efficiency and reduced nighttime awakenings (all p<.001); changes in total sleep time were nonsignificant (p=.22). PVT reciprocal mean reaction times were also significantly faster (p=.001; medium effect size).

Conclusions

This study demonstrated that among women attending a brief residential early parenting program, fatigue, daytime sleepiness, and objectively measured psychomotor vigilance can be improved. Implications for further research and potential treatments are discussed.

Abstract

Aim

To test the association between cardiometabolic risk factors and subjective sleep quality assessed by the Pittsburgh sleep quality index (PSQI), independent of obstructive sleep apnea (OSA) and sleep duration.

Methods

A total of 573 participants from the Baependi Heart Study, a rural cohort from Brazil, completed sleep questionnaires and underwent polygraphy for OSA evaluation. Multivariable linear regression analysis tested the association between cardiovascular risk factors (outcome variables) and sleep quality measured by PSQI, adjusting for OSA and other potential confounders (age, sex, race, salary/wage, education, marital status, alcohol intake, obesity, smoking, hypertension, and sleep duration).

Results

The sample mean age was 43±16 years, 66% were female, and mean body mass index (BMI) was 26±5 kg/m2. Only 20% were classified as obese (BMI ≥30). Fifty per cent of participants reported poor sleep quality as defined by a PSQI score ≥5. A high PSQI score was significantly associated with higher very-low-density lipoprotein (VLDL) cholesterol levels (beta=0.392, p=0.012) and higher triglyceride levels (beta=0.017, p=0.006), even after adjustments, including the apnea–hypopnea index. Further adjustments accounting for marital status, alcohol intake, and medication use did not change these findings. No significant association was observed between PSQI scores and glucose or blood pressure. According to PSQI components, sleep disturbances (beta=1.976, p=0.027), sleep medication use (beta=1.121, p=0.019), and daytime dysfunction (beta=1.290, p=0.024) were significantly associated with higher VLDL serum levels. Only the daytime dysfunction domain of the PSQI components was significantly associated with higher triglyceride levels (beta=0.066, p=0.004).

Conclusion

Poorer lipid profile was independently associated with poor sleep quality, assessed by the PSQI questionnaire, regardless of a normal sleep duration and accounting for OSA and socio-economic status.
