Subjective effects of the sleep position trainer on snoring outcomes in position-dependent non-apneic snorers

Purpose: To evaluate the effect of a new-generation positional device, the sleep position trainer (SPT), in non-apneic position-dependent snorers. Methods: Non-apneic position-dependent snorers with an apnea–hypopnea index (AHI) < 5 events/h were included between February 2015 and September 2016. After inclusion, study subjects used the SPT at home for 6 weeks. The Snore Outcome Survey (SOS) was filled out by the subjects at baseline and after 6 weeks, and at the same time, the Spouse/Bed Partner Survey (SBPS) was filled out by their bed partners. Results: A total of 36 participants were included and 30 completed the study. SOS score improved significantly after 6 weeks from 35.0 ± 13.5 to 55.3 ± 18.6, p < 0.001. SBPS score also improved significantly after 6 weeks from 24.7 ± 16.0 versus 54.5 ± 25.2, p < 0.001. The severity of snoring assessed with a numeric visual analogue scale (VAS) by the bed partner decreased significantly from a median of 8.0 with an interquartile range (IQR) of [7.0–8.5] to 7.0 [3.8–8.0] after 6 weeks (p = 0.004). Conclusions: Results of this study indicate that positional therapy with the SPT improved several snoring-related outcome measures in non-apneic position-dependent snorers. The results of this non-controlled study demonstrate that this SPT could be considered as an alternative therapeutic option to improve sleep-related health status of snorers and their bed partners

Effect of weight regain on body composition and metabolic biomarkers after sleeve gastrectomy: a cross-sectional study from a hospital database

Introduction Weight regain (WR) is described in approximately 30% of patient's post-bariatric surgery. It is related to the progression or recurrence of associated medical problems and decline in health-related quality of life. This study aimed to test the return of body composition and metabolic biomarkers to pre-operative levels when WR occurs. Methods In this cross-sectional study conducted in 2021, patients were randomly selected from the hospital's electronic databases between 2001 and 2020. Patient demographic data, comorbidities, body compositions, and metabolic biomarkers were collected. Three groups were defined: groups A (WR), B (weight loss), and C (control group; patients with obesity who had not yet undergone bariatric surgery). Results A total of 88 patients were enrolled in this study and matched with the control group. The body mass index in group A was 43.8 +/- 6.9 kg/m(2); group B was 28.6 +/- 4.2; group C was 43.9 +/- 7.1. Body muscle mass, body fat mass, and visceral fat significantly differed between groups A and B (p < 0.001) but not between groups A and C (p = 0.8). There was a significant difference in leptin, ghrelin, postprandial glucagon-like peptide-1, insulin, and fibroblast growth factor-21 (but not retinol-binding protein-4) between groups A and B. Most metabolic biomarkers in group A returned to the pre-operative values as in group C. Conclusion WR had a direct negative effect on body composition and metabolic biomarkers, whereby the values returned to pre-operative levels. Early detection of WR and possible additional therapy are necessary to prevent associated medical problems

The Tetraspanin Protein CD37 Regulates IgA Responses and Anti-Fungal Immunity

Immunoglobulin A (IgA) secretion by plasma cells in the immune system is critical for protecting the host from environmental and microbial infections. However, the molecular mechanisms underlying the generation of IgA+ plasma cells remain poorly understood. Here, we report that the B cell–expressed tetraspanin CD37 inhibits IgA immune responses in vivo. CD37-deficient (CD37−/−) mice exhibit a 15-fold increased level of IgA in serum and significantly elevated numbers of IgA+ plasma cells in spleen, mucosal-associated lymphoid tissue, as well as bone marrow. Analyses of bone marrow chimeric mice revealed that CD37–deficiency on B cells was directly responsible for the increased IgA production. We identified high local interleukin-6 (IL-6) production in germinal centers of CD37−/− mice after immunization. Notably, neutralizing IL-6 in vivo reversed the increased IgA response in CD37−/− mice. To demonstrate the importance of CD37—which can associate with the pattern-recognition receptor dectin-1—in immunity to infection, CD37−/− mice were exposed to Candida albicans. We report that CD37−/− mice are evidently better protected from infection than wild-type (WT) mice, which was accompanied by increased IL-6 levels and C. albicans–specific IgA antibodies. Importantly, adoptive transfer of CD37−/− serum mediated protection in WT mice and the underlying mechanism involved direct neutralization of fungal cells by IgA. Taken together, tetraspanin protein CD37 inhibits IgA responses and regulates the anti-fungal immune response

Study Porous titanium cervical interbody fusion device in the treatment of degenerative cervical radiculopathy; 1-year results of a prospective controlled trial

BACKGROUND CONTEXT: Anterior cervical discectomy with an interbody cage (ACDF) to obtain fusion is a common procedure in cervical spine surgery. Presently, polyetheretherketone (PEEK) with (auto) graft is frequently used for interbody fusion although alternative implant tech- nology like 3-D printing titanium has been introduced recently. PURPOSE: Reporting the clinical and quantitative radiological outcome of a prospective cohort of 3-D printed porous titanium implants. STUDY DESIGN/SETTING: Prospective study of patients with single level ACDF using 3-D printed porous titanium cervical implants. These data were compared with 48 patients from the PEEK with autograft group of the previously performed CAncellous Structured Ceramic Arthrode- sis DEvice trial. PATIENT SAMPLE: Fourty-nine patients were included. OUTCOME MEASURES: Neck disability index (NDI), visual analog scale (VAS), self -reported perceived recovery, and fusion status. METHODS: The clinical outcomes and fusion rates were documented at 3, 6, and 12 months. Dynamic X-rays were analyzed to determine range of motion (ROM) of the operated level. Fusion was defined as rotation <= 4 degrees and <= 1.25 mm translation on flexion -extension films. RESULTS: The mean NDI improved from 41.2 preoperatively to 19.4 at 12 months postopera- tively. Both VAS arm and VAS neck improved significantly after surgery and 77.1% of the patients reported complete or nearly complete recovery at 12 months. The mean ROM of the affected disc level decreased from 8.7 degrees (range 2.6 -21.4) before surgery to 1.6 degrees (0.0 -4.6 degrees) after 12 months. The fusion rate at 3, 6, and 12 months was 84%, 89%, and 91% respectively, compared with 67%, 72%, and 90%, in the PEEK group. CONCLUSIONS: 3-D printed porous titanium cervical implants resulted in significant clinical improvement after surgery. The fusion rate of porous titanium compared with PEEK with autograft at 12 months was similar, although porous titanium resulted in faster consolidation. In addition, one level anterior cervical fusion can be successfully achieved without additional plating. (c) 2020 Elsevier Inc.

Single Center and Surgeon's Long-Term (15-19 Years) Patient Satisfaction and Revision Rate of Round Textured Eurosilicone Breast Implants

Background Breast augmentation is one of the most commonly performed aesthetic plastic surgical procedures, with over 250,000 procedures in the United States in 2020 alone. However, the safety of breast implants should be closely researched and monitored, especially in the long term.Objectives This study was undertaken to evaluate the long-term results of round micro-textured Eurosilicone (Eurosilicone S.A.S, Apt Cedex, France) Cristalline Paragel breast implants from a single-center, single-surgeon experience regarding both patient-reported outcome measures and revisions.Methods A retrospective cohort study was undertaken of 84 patients who underwent primary breast augmentation with round micro-textured Eurosilicone Cristalline Paragel breast implants, either submuscular (dual-plane) or subglandular placed, between 2001 and 2004. All patients were contacted for informed consent, and after approval, the validated BREAST-Q questionnaire was sent and utilized to analyze patient satisfaction. In addition, objective data regarding revisions, including capsular contracture, rupture rate, pain, and/or aesthetic causes needing revision surgery, were analyzed.Results High BREAST-Q scores (67%-100% for 0-100 scale variables and 66.0%-77.3% of the patients scored "very satisfied" on categorical variables) were found without clinically significant differences between patients with dual-plane-placed implants and subglandular-placed implants. The overall revision rate was 29.8%, also with no significant differences between groups (P = 0.317).Conclusions This study showed high patient satisfaction and relatively low revision rates after 15 to 19 years of follow-up of round micro-textured Eurosilicone Cristalline Paragel breast implants. No clinically relevant significant differences were found between dual-plane and subglandular placement of the implants.Level of Evidence:

Differences Between the 2016 and 2022 Editions of the Enhanced Recovery After Bariatric Surgery (ERABS) Guidelines: Call to Action of FAIR Data and the Creation of a Global Consortium of Bariatric Care and Research

In 2016, the Enhanced Recovery After Bariatric Surgery guidelines (G16) was published, and in 2022, an update to it was released (G22). Grading of recommendations, assessment, development, and evaluations (GRADE), emphasizing the level of evidence (LoE) of both the guidelines, was performed. An overview of methodology was also performed, considering the following questions: how can research be improved, what can be done in the future using data, and how to collaborate more? Both guidelines did not explain how the LoE conclusions were derived regarding the risk of bias. There is also potential for forming a global consortium that deals with bariatric research, which can serve as a repository for all relevant data. Ensuring that this data is FAIR (findability, accessibility, interoperability, reusability) compliant and using this data to formulate future guidelines will benefit clinicians and patients alike

Psychological distress in the hospital setting: a comparison between native Dutch and immigrant patients

Prevalence of psychological distress (i.e. depressive and anxiety symptoms) in medically ill patients is high. Research in the general population shows a higher prevalence of psychological distress among immigrants compared to natives. Our aim was to examine the prevalence of psychological distress in the hospital setting comparing immigrant and native Dutch patients and first and second generation immigrant patients.Prevalence of psychological distress was assessed using the extended Kessler-10 (EK-10) in 904 patients in a Dutch general teaching hospital. Logistic regression was used to calculate odds ratios to determine differences between native and immigrant patients and first and second generation immigrants in the prevalence of psychological distress. We adjusted for demographic and social variables, socio-economic status, physical quality of life, history of psychiatric disease and health care use.Of 904 patients, 585 were native Dutch patients and 319 were immigrant patients. The prevalence of psychological distress in native compared to immigrant patients was 54% and 66% respectively, with especially high prevalences among Turkish and Moroccan immigrant patients. The crude OR for prevalence of psychological distress for immigrant patients versus native patients was 1.7 (95% CI 1.2-2.2) and for first versus second generation immigrant patients 2.1 (95% CI 1.2-3.5). After full adjustment ORs were 1.7 (95% CI 1.2-2.3) and 2.2 (95% CI 1.2-4.1) respectively.Immigrant patients and first generation immigrant patients were more likely to have psychological distress compared to native patients and second generation immigrant patients respectively. We found a particularly high prevalence of psychological distress in Turkish and Moroccan immigrants
