Recombinant human Hsp110-gp100 chaperone complex vaccine is nontoxic and induces response in advanced stage melanoma patients

xlomafota13 shared this article with you from Inoreader Recombinant human Hsp110-gp100 chaperone complex vaccine is nontoxic and induces response in advanced stage melanoma patients Via Melanoma Research - Current Issue Heat shock proteins (hsp) are intracellular chaperones that possess extracellular immunostimulatory properties when complexed with antigens. A recombinant Hsp110-gp100 chaperone complex vaccine showed an antitumor response and prolonged survival in murine melanoma. A phase Ib dose-escalation study of a recombinant human Hsp110-gp100 vaccine in advanced-stage melanoma patients was performed to evaluate toxicity, immunostimulatory potential and clinical response. Patients with pretreated, unresectable stage IIIB/C/IV melanoma received the chaperone complex vaccine in a dose-escalation protocol; three vaccinations over a 43-day-period. Tumor response, clinical toxicity and immune response were measured. Ten patients (eight female, median age 70 years) were enrolled and two patients had grade 1 adverse events; minor skin rash, hyperhidrosis and fever (no grade 2 or higher adverse events). Median progression-free survival was longer for lower vaccine doses as compared to the maximum dose of 180 mcg (4.5 vs. 2.9 months; P = 0.018). The lowest dose patients (30 and 60 mcg) had clinical tumor responses (one partial response, one stable disease). CD8+ T cell interferon-γ responses to gp100 were greater in the clinically responding patients. A pattern of B cell responses to vaccination was not observed. Regulatory T cell populations and co-stimulatory molecules including cytotoxic T-lymphocyte-associated protein 4 and PD-1 appeared to differ in responders versus nonresponders. A fully recombinant human Hsp110-gp100 chaperone complex vaccine had minimal toxicity, measurable tumor responses at lower doses and produced peripheral CD8+ T cell activation in patients with advanced, pretreated melanoma. Combination with currently available immunotherapies may augment clinical responses. View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.

Real-world frequency of BRAF testing and utilization of therapies in patients with advanced melanoma

xlomafota13 shared this article with you from Inoreader Real-world frequency of BRAF testing and utilization of therapies in patients with advanced melanoma Via Melanoma Research - Current Issue Both BRAF/MEK targeted agents and immunotherapy are approved for the treatment of advanced melanoma. BRAF testing is recommended at the time of advanced melanoma diagnosis. In addition, little is known regarding the treatment trends for patients with BRAF mutated tumors. This investigation aims to assess the real-world prevalence of molecular testing and treatment trends for patients with BRAF mutated tumors. Using a de-identified database, patients of age ≥18 years with advanced melanoma from 2013 to 2018 were examined. Molecular testing performed within 3 months of advanced diagnosis was considered to have the test pe rformed at the time of diagnosis. Test prevalence was calculated and compared in groups stratified by the patient, tumor and treatment factors. In total 4459 patients were included; 1936 (43.4%) stage III, 1191 (26.7%) stage IV and 1332 (29.9%) recurrent. Totally 50.4% of patients received systemic treatment; 76.4% stage IV, 71% recurrent patients and 26.7% stage III patients. However, 73.5% received first-line immunotherapy. In total 73.8% of patients had molecular testing, and 50.5% had tested at the time of advanced diagnosis. Of those tested 42% had a BRAF mutated tumor. In total 48% of these patients received first-line immunotherapy whereas 43% received a BRAF inhibitor, with increasing immunotherapy use seen over time. The majority of patients with advanced melanoma undergo molecular testing at the time of advanced diagnosis. Immunotherapy is the most commonly prescribed treatment regardless of BRAF mutational status. These results provide real-world data on the frequency of molecular testing and treatment trends for patients with advanced melanoma. View on the web Inoreader. Take back control of your news feed.

xlomafota13 shared this article with you from Inoreader Proof-of-concept of a new FFP2 mask adapted to Otolaryngological practice in pandemic: a prospective study Via http://link.springer.com/journal/405,European archives of oto-rhino-laryngology,The European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino Eur Arch Otorhinolaryngol. 2022 Mar 14. doi: 10.1007/s00405-022-07319-5. Online ahead of print. ABSTRACT OBJECTIVE: The objective of this study was to appreciate the tolerance and convenience of a new FFP2 mask allowed the realization of nasal examination in period of pandemic. METHODS: Fifty-one patients were prospectively recruited from two European hospitals to test the FFP2 mask prototype. The following outcomes were evaluated in patients after the clinical examination: fear about coronavirus disease 2019 (COVID-19) infection; easiness of mask placement; tolerability; reassurance; and overall satisfaction about the use of this kind of mask in a pandemic context. Seven otolaryngologists evaluated the mask acceptance and usefulness in patients through a standardized physician-reported outcome questionnaire. RESULTS: Fifty patients completed the evaluation. There were 25 males and 25 females. The mean age of patients was 4 1 years. Ninety percent of patients considered that the use of the mask reduced the risk to be infected during the examination. Seventy percent of patients reported high or very high satisfaction and should recommend mask to other patients in pandemic period. The realization of nasal examination was easier with optic compared with flexible trans-nasal examination (p = 0.001), which significantly impacted the satisfaction level of physician (p = 0.001). The physician difficulty to perform the examination significantly impacted the satisfactory of patient (p = 0.033). CONCLUSION: The new bioserenity FFP2 mask allows the realization of the trans-nasal endoscopic examination during a pandemic. The use of this mask requires little training period of physician. The use of this mask prototype is well received by patients who reported better perception of self-protection against the virus.

The computed tomographic evaluation of bony bridge of C1 as bleeding risk factor at the screw placement

xlomafota13 shared this article with you from Inoreader The computed tomographic evaluation of bony bridge of C1 as bleeding risk factor at the screw placement Via radiol anat Surg Radiol Anat. 2022 Mar 14. doi: 10.1007/s00276-022-02919-6. Online ahead of print. ABSTRACT PURPOSE: To investigate the prevalence and morphological characteristics of ponticulus posticus (PP) and ponticulus lateralis (PL) using computed tomography (CT) images on a large study sample of the Anatolian population. The presence of the PP and PL bridges can limit gap available for placement procedure through the bony elements of C1. Routine screw techniques are contraindicat ed because of high risk of fatal bleeding of vertebral artery (VA). METHODS: The CT images of 1000 subjects (500 males, 500 females) were examined for the morphological characteristics and presence of PP and PL. The anteroposterior diameter, superoposterior (transverse) diameter, surface area, and central thickness of the bony bridge of the PP, PL, and transverse foramina (TF). RESULTS: The prevalence of PP was 14.8%, and bilateral complete PP was the most common PP type at 6.8%. The prevalence of PL was 4.1% and left-side complete PL was the most common PL type at 1.2%. The prevalence of both PP and PL was more common in males and bilateral complete PP were more predominant in males (p = 0.004, p = 0.038, and p = 0.010, respectively). The surface area of PP and PL were determined to be smaller than the surface area of the ipsilateral TF (p < 0.001 and p = 0.042, respectively). CONCLUSION: PP is not an uncommon anatomic anomaly and PL is even less frequently enc ountered. The prevalence of PP and PL was more common in males and bilateral complete PP was more predominant in males. Detailed information about the prevalence and morphometry of the PP and PL obtained in the present study could guide the clinicians dealing with neurosurgery, physical medicine and rehabilitation, and radiology in their practice.

xlomafota13 shared this article with you from Inoreader Diagnosis and correction of the obstructive sleep apnea syndrome in children with tonsillar ring pathological conditions Via Vestnik otorinolaringologii Vestn Otorinolaringol. 2022;87(1):4-8. doi: 10.17116/otorino2022870114. ABSTRACT To summarize the results of a study of the clinical and polygrapic features of sleep in children with pathologic conditions of the tonsillar ring and obstructive sleep apnea. Tonsillar hypertrophy is the most common cause of obstructive sleep apnea in children. Using the data of overnight polysomnographic study and/or nocturnal pulse oximetry, groups of patients were distinguished depending on the presence and severity of their sleep breathing disorders. The effectiveness of adenotomy, adenotonsillotomy and/or adenotonsillectomy in children is demonstrated, depending on the severity of obstructive sleep apnea syndrome. Evaluation of breathing in sleeping children by polygraphic methods is necessary for early detection of obstructive sleep apnea syndrome and monitoring the effectiveness of surgical treatment.

Hearing loss due to mutations in the genes responsible for Usher syndrome

xlomafota13 shared this article with you from Inoreader Hearing loss due to mutations in the genes responsible for Usher syndrome Via Vestnik otorinolaringologii Vestn Otorinolaringol. 2022;87(1):52-59. doi: 10.17116/otorino20228701152. ABSTRACT Usher syndrome is characterized by congenital bilateral sensorineural hearing loss and progressive retinitis pigmentosa, and has an autosomal recessive type of inheritance. The purpose of this work is to summarize the modern data of a clinical picture of Usher syndrome and analyse hearing impairment properties. The frequency of the syndrome among children suffering from hearing loss and deafness is from 3 to 10%. The prevalence of the syndrome in the world is estimated as 4.4 per 100.000 population. The complexity of the diagnosis of the syndrome lies in the significant clinical and genetic heterogeneity. Hearing and vision problems begin at different ages. Primary diagnosis begins with the clinical diagnosis of bilateral hearing loss and visual impairment manifests later. In this case the initial diagnosis of nonsyndromal hearing loss will not be defin itive. Molecular genetic studies contribute to the early clinical diagnosis of the syndrome. Understanding the cause of the disease allows to conduct correct medical and genetic counseling and get closer to solving treatment problems.
