The COVID-19 pandemic has exacerbated the significance of burn injuries as a critical public health challenge, demanding the exploration of effective strategies for prevention and care, particularly for individuals with burns. This retrospective observational cohort study aimed to analyze the characteristics of adult burn patients admitted to three reference centers in Iran from October 2020 to October 2023. The study focused on patients and burn wound characteristics, complications and morbidities, and treatment plans. Among the 382 patients aged 20 to 84, our findings suggested that being male decreased the likelihood of COVID-19 infection by about 77 %. Thermal burns accounted for 50.2 % of COVID-19-positive patients and 49.8 % of COVID-19-negative patients. Notably, the risk of COVID-19 infection increased with higher degrees of burn (p = 0.006) in both groups. Among the complications, pneumonia (p = 0.003) and paralytic ileus (p = 0.015) were significantly more common in COVID-19-positive patients. Additionally, COVID-19-positive patients underwent more frequent interventions such as skin grafting (p = 0.035) and surgical debridement (p = 0.030). These findings emphasize the importance of a carefully planned and proactive multidisciplinary management strategy to ensure optimal care for burn patients.

ObjectivesUnderstanding the potential impact of physical characteristics of the urban environment on clinical outcomes on several mental illnesses.Materials and MethodsPhysical features of the urban environment were examined as predictors for affective and non-affective several mental illnesses (SMI), the number and length of psychiatric hospital admissions, and the number of short and long-acting injectable antipsychotic prescriptions. In addition, the urban features with the greatest weight in the predicted model were determined. The data included 28 urban features and 6 clinical variables obtained from 30,210 people with SMI receiving care from the South London and Maudsley NHS Foundation Trust (SLaM) using the Clinical Record Interactive Search (CRIS) tool. Five machine learning regression models were evaluated for the highest prediction accuracy followed by the Self-Organising Map (SOM) to represent the results visually.ResultsThe prevalence of SMI, number and duration of psychiatric hospital admission, and antipsychotic prescribing were greater in urban areas. However, machine learning analysis was unable to accurately predict clinical outcomes using urban environmental data.DiscussionThe urban environment is associated with an increased prevalence of SMI. However, urban features alone cannot explain the variation observed in psychotic disorder prevalence or clinical outcomes measured through psychiatric hospitalisation or exposure to antipsychotic treatments.ConclusionUrban areas are associated with a greater prevalence of SMI but clinical outcomes are likely to depend on a combination of urban and individual patient-level factors. Future mental healthcare service planning should focus on providing appropriate resources to people with SMI in urban environments.

Background:. Skin lesions and traumas can affect the skin by leaving scars. The purpose of this study was evaluating the results of a new technique in reconstructive surgery of scars on the nose. In this technique, extra skin remaining from reduction rhinoplasty is applied to the defect remained from removing the scar. Methods:. This is a retrospective cross-sectional study performed on 33 patients who underwent reduction rhinoplasty from 2013 to 2018 due to scars on the dorsal nasal skin. Five sets of standards, criteria, and questionnaires were used to evaluate the cosmetic outcomes, scars, and nasal function. These included the Cakir concept, visual analogue scale, patient reported outcome measurement, Stony Brook scar evaluation scale, and sino-nasal outcome test-22. Results:. According to the surface polygon concept, or Cakir concept, the number of affected polygons due to scars decreased in all included patients (P < 0.05). In addition, constant improvement in patients’ satisfaction, based on patient reported outcome measurement (P < 0.001) and visual analogue scale (P ≤ 0.05), as well as physicians’ satisfaction, based on Stony Brook scar evaluation scale, were determined. Furthermore, evaluating the patients’ breathing, based on sino-nasal outcome test-22 criteria (P < 0.09), indicated no adverse effects. Conclusion:. Excision of scars from dorsal nasal skin and conducting rhinoplasty surgery from the same access can be considered an option for reconstructing nasal scars.

Study DesignDescriptive cross-sectional study.PurposeTo determine the prevalence of vitamin D deficiency in patients with degenerative diseases of the spine about to undergo spinal surgery and the relations between such deficiency and potential risk factors.Overview of LiteratureVitamin D has a major role in musculoskeletal system health maintenance. Recently, studies on degenerative diseases of the spine have shown a high prevalence of vitamin D deficiency in patients undergoing spine surgery.MethodsSerum levels of 25(OH)D were determined by an electrochemiluminescence detection assay. The other variables were determined through relevant questionnaires, and the data was analyzed through analysis of variance, t-test, chi-square and multivariate logistic regression analysis.ResultsA total of 110 patients were enrolled in the study. The mean serum level of 25(OH)D was 27.45±18.75 ng/mL, and 44.5% of patients showed vitamin D deficiency (25(OH)D
