RESUMEN
BACKGROUND: Allergic diseases impose a significant global disease burden, however, the influence of light at night exposure on these diseases in humans has not been comprehensively assessed. We aimed to summarize available evidence considering the association between light at night exposure and major allergic diseases through a systematic review and meta-analysis. METHODS: We completed a search of six databases, two registries, and Google Scholar from inception until December 15, 2023, and included studies that investigated the influence of artificial light at night (ALAN, high vs. low exposure), chronotype (evening vs. morning chronotype), or shift work (night vs. day shift work) on allergic disease outcomes (asthma, allergic rhinitis, and skin allergies). We performed inverse-variance random-effects meta-analyses to examine the association between the exposures (ALAN exposure, chronotype, or shiftwork) and these allergic outcomes. Stratification analyses were conducted by exposure type, disease type, participant age, and geographical location along with sensitivity analyses to assess publication bias. RESULTS: We included 12 publications in our review. We found that exposure to light at night was associated with higher odds of allergic diseases, with the strongest association observed for ALAN exposure (OR: 1.88; 95% CI: 1.04 to 3.39), followed by evening chronotype (OR: 1.35; 95% CI: 0.98 to 1.87) and exposure to night shift work (OR: 1.33; 95% CI: 1.06 to 1.67). When analyses were stratified by disease types, light at night exposure was significantly associated with asthma (OR: 1.62; 95% CI: 1.19 to 2.20), allergic rhinitis (OR: 1.89; 95% CI: 1.60 to 2.24), and skin allergies (OR: 1.11; 95% CI: 1.09 to 1.91). We also found that the association between light at night exposure and allergic diseases was more profound in youth (OR: 1.63; 95% CI: 1.07 to 2.48) than adults (OR: 1.30; 95% CI: 1.03 to 1.63). Additionally, we observed significant geographical variations in the association between light at night exposure and allergic diseases. CONCLUSIONS: Light at night exposure was associated with a higher prevalence of allergic diseases, both in youth and adults. More long-term epidemiological and mechanistic research is required to understand the possible interactions between light at night and allergic diseases.

Artificial light at night (ALAN) exposure is associated with the disruption of human circadian processes. Through numerous pathophysiological mechanisms such as melatonin dysregulation, it is hypothesised that ALAN exposure is involved in asthma and allergy, mental illness, and cancer outcomes. There are numerous existing studies considering these relationships; however, a critical appraisal of available evidence on health outcomes has not been completed. Due to the prevalence of ALAN exposure and these outcomes in society, it is critical that current evidence of their association is understood. Therefore, this systematic scoping review will aim to assess the association between ALAN exposure and asthma and allergy, mental health, and cancer outcomes. This systematic scoping review will be conducted in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses statement. We will search bibliographic databases, registries, and references. We will include studies that have described potential sources of ALAN exposure (such as shift work or indoor and outdoor exposure to artificial light); have demonstrated associations with either allergic conditions (including asthma), mental health, or cancer-related outcomes; and are published in English in peer-reviewed journals. We will conduct a comprehensive literature search, title and abstract screening, full-text review, and data collection and analysis for each outcome separately.

Respiratory oscillometry is gaining global attention over traditional pulmonary function tests for its sensitivity in detecting small airway obstructions. However, its use in clinical settings as a diagnostic tool is limited because oscillometry lacks globally accepted reference values. In this scoping review, we systematically assessed the differences between selected oscillometric reference equations with the hypothesis that significant heterogeneity existed between them. We searched bibliographic databases, registries and references for studies that developed equations for healthy adult populations according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A widely used Caucasian model was used as the standard reference and compared against other models using Bland-Altman and Lin's concordance correlational analyses. We screened 1202 titles and abstracts, and after a full-text review of 67 studies, we included 10 in our analyses. Of these, three models had a low-to-moderate agreement with the reference model, particularly those developed from non-Caucasian populations. Although the other six models had a moderate-to-high agreement with the standard model, there were still significant sex-specific variations. This is the first systematic analysis of the heterogeneity between oscillometric reference models and warrants the validation of appropriate equations in clinical applications of oscillometry to avoid diagnostic errors.

INTRODUCTION: Surgical technique varies dramatically in the performance of laparoscopic Roux-en-Y gastric bypass (LRYGB) and these differences can potentially lead to variation in outcomes. The objective of this study was to characterize surgical techniques used during LRYGB. METHODS: An anonymous 44-question survey was distributed by email to all bariatric surgeons with membership in the ASMBS, SAGES, and ACS from April to June 2020. Questions were designed to evaluate surgeon demographics, experience, and variation of techniques. Only surgeons who performed LRYGB within the past year were included for analysis. RESULTS: A total of 534 (18.8%) surgeons responded and the majority (97.0%) reported performing LRYGB in the past year. Surgeons were predominantly from the USA (77.8%). For preoperative work-up, 20.1% performed upper gastrointestinal series while 60.8% performed esophagogastroduodenoscopy. Limb length evaluation revealed mean Roux and biliopancreatic limb lengths of 124.1 ± 29.4 cm and 67.4 ± 32.2 cm, respectively. The gastrojejunostomy was most commonly formed using a linear stapler with handsewn closure of the common enterotomy (53.1%) and the jejunojejunostomy using a linear stapled anastomotic technique with handsewn closure of the common enterotomy (60.6%). The majority of surgeons closed the jejunojejunostomy mesenteric defect (91.1%) and one of the antecolic or retrocolic mesenteric defects (65.1%). Intraoperative leak tests were performed in 95.9% of cases. Only 22.1% of surgeons routinely performed upper gastrointestinal swallow studies postoperatively. CONCLUSIONS: There are wide variations in pre- and intraoperative practice patterns for LRYGB. Further clinical trials designed to evaluate the impact of these practice pattern differences on patient outcomes are warranted.

BACKGROUND: Hepato-pancreatico-biliary (HPB) patients experience significant risk of preoperative frailty. Studies assessing preventative prehabilitation in HPB populations are limited. This systematic review and meta-analysis evaluates outcomes for HPB patients treated with exercise prehabilitation. DATA SOURCES: A comprehensive search of MEDLINE (via Ovid), Embase (Ovid), Scopus, Web of Science Core Collection, Cochrane Library (Wiley), ProQuest Dissertations, Theses Global, and Google Scholar was conducted with review and extraction following PRISMA guidelines. Included studies evaluated more than 5 adult HPB patients undergoing ≥ 7-day exercise prehabilitation. The primary outcome was postoperative length of stay (LOS); secondary outcomes included complications, mortality, physical performance, and quality of life. RESULTS: We evaluated 1778 titles and abstracts and selected 6 (randomized controlled trial, n = 3; prospective cohort, n = 1; retrospective cohort, n = 2) that included 957 patients. Of those, 536 patients (56.0%) underwent exercise prehabilitation and 421 (44.0%) received standard care. Patients in both groups were similar with regards to important demographic factors. Prehabilitation was associated with a 5.20-day LOS reduction (P = 0.03); when outliers were removed, LOS reduction decreased to 1.85 days and was non-statistically significant (P = 0.34). Postoperative complications (OR = 0.70; 95% CI: 0.39 to 1.26; P = 0.23), major complications (OR = 0.83; 95% CI: 0.60 to 1.14; P = 0.24), and mortality (OR = 0.67; 95% CI: 0.17 to 2.70; P = 0.57) were similar. Prehabilitation was associated with improved strength, cardiopulmonary function, quality of life, and alleviated sarcopenia. CONCLUSIONS: Exercise prehabilitation may reduce LOS and morbidity following HPB surgery. Studies with well-defined exercise regimens are needed to optimize exercise prehabilitation outcomes.

INTRODUCTION: Cameron lesions (CL) are an under-recognized cause of gastrointestinal bleeding. Diagnosis is often impaired by technical difficulty, and once diagnosed, management remains unclear. Typically, patients are medically managed with proton pump inhibitors (PPI). Small studies have demonstrated improved therapeutic success with surgical management, hypothesizing that reversing mechanical gastric trauma and ischemia allows CL healing. This systematic review and meta-analysis aim to compare therapeutic success of surgical versus medical management of Cameron lesions (CL). METHODS AND PROCEDURES: A comprehensive search and systematic review selected manuscripts using the following inclusion criteria: (1) Endoscopically diagnosed CL (2) Treated surgically (3) Follow-up for resolution of anemia or CL (4) n ≥ 5 (5) Excluding non-English, animal, and studies with patients < 18 years old Meta-analysis was performed to compare resolution of CLs with medical and surgical therapy. RESULTS: Systematic search retrieved 1664 studies, of these, 14 were included (randomized controlled trial = 1; prospective = 2; retrospective = 11). Patients had a mean age of 61.2 years (range 24-91) and were more often female (59.3%). Follow-up was between 3 and 120 months, and 82.9% of patients had hernias > 5 cm. Surgical management was associated with therapeutic success (OR 5.20, 1.83-14.77, I2 = 42%, p < 0.001) with 92% having resolution, compared to 67.2% for those treated with PPI. Surgical complications occurred in 42/109 (38.5%) of patients (48.1% for Open Hill Repair, 15.4% for laparoscopic fundoplication). 40.0% of patients underwent a laparoscopic Nissen or Collis fundoplication, 21.7% underwent open modified Hill repair, and 38.3% had unspecified operations. Hemoglobin improved from 8.85 g/dL pre-operatively to 13.60 g/dL post-operatively. In six studies, surgical patients previously failed medical management. CONCLUSIONS: This is the first systematic review comparing surgical and medical treatment of CL. Surgical management significantly improved therapeutic success. Our study supports therapeutic benefit of surgery in these patients.
