Enteric Dysbiosis in Children With Autism Spectrum Disorder and Associated Response to Stress.

Background Microbiome studies in humans, though limited, have facilitated the evaluation of the potential connection between the microbiome and brain function. Children with autism spectrum disorder (ASD) have several behavioral challenges and avoidant/restrictive food intake disorder, which may contribute to gut microbiome dysbiosis. Aim The aim of this study is to examine the extent to which the gut microbiome of children with ASD differs in comparison to children with neurotypical development (CWND) and to assess whether a probiotic intervention has the potential to influence the gut microbiome in mediating positive behavior change and stress regulation. Methods This pilot study collected data from three children with ASD and four CWND before and after a four-week probiotic intervention. Data collection included microbiome diversity screening from stool samples as well as the following biophysiological measures: salivary alpha-amylase (sAA) levels, response to simulated stressor and calming stimulus (behavior), including pulse rate, galvanic skin response, and pupil diameter (PD). In addition, telomere length was assessed. All measures, except for telomere length, were repeated after the four-week intervention on the ASD and CWND groups for pre-/post-comparison. Data analysis consisted of multivariate analyses, including ANOVA. Results While greater heterogeneity in the ASD group was evident in all measures, the gut microbiome of participants who received probiotic intervention differed from pretreatment results within and across the groups investigated. Further, the biophysiological parameter sAA displayed a significant increase between baseline and exposure to stress in both groups, whereas PD increased in both groups from baseline, F(11, 26615) = 123.43, p = 0.00. Conclusion Though gut microbiome diversity is diminished in children with ASD compared to CWND, the gap is narrowed following a brief probiotic intervention. The results suggest that probiotic interventions have the potential to rescue microbiome diversity and abundance, potentially supporting stress regulation in pediatric populations.

Adverse Events Associated With Disparity Between Patients' BMI and Operating Table Size-A Need for Improved Surgical Innovations.

BACKGROUND: The lack of proper equipment to accommodate patients with high BMI can jeopardize the safety of the patients and medical staff. In this review, we aim to discuss the availability of obesity accommodations in the operating room, along with its impact, implications, and future recommendations. METHODS: Four databases were searched for articles pertaining to surgical table dimensions and the implications for safety, with a special focus on patients with larger BMIs. Articles were separated into 4 categories: Existing OR Table Options, Safety Implications for Patients, Reported Adverse Events Associated with Operating Table Inadequacy, and Safety Implications for Medical Staff. RESULTS: A total of 18 articles and documents were included in this review. Most of the literature that discusses surgical tables with higher weight capacity is specific only to weight loss surgeries. Operating table dimensions have changed little in the past 100 years and standard operating tables have weight limits of 500 pounds. Several case reports underline the hazards of inadequately sized surgical tables. CONCLUSIONS: This review demonstrates that a lack of proper equipment, such as surgical tables with adequate width and weight limits, can be a major contributor to the endangerment of bariatric surgical patients and the medical professionals who care for them. Further research and surgical innovation may be required to develop superior operating tables to address the unique concerns of this patient populations.

A focused report on progestogen hypersensitivity.

INTRODUCTION: Progestogen Hypersensitivity (PH) is caused by increased sensitivity to either exogenous or endogenous progestogens. It is characterized by recurrent cutaneous eruptions including erythema multiforme, eczema, urticaria, and angioedema, which may be associated with systemic symptoms including asthma and anaphylaxis. AREAS COVERED: Symptoms may be persistent or cyclical, coinciding with progestogen levels. With increased use of oral contraceptives and hormonal treatments for fertility, the prevalence of PH is expected to continuously increase. Several proposed immunological mechanisms, diagnostics, and treatment modalities have been proposed. Most treatments focus on suppressing ovulation and progesterone secretion or inducing tolerance through progesterone desensitization. EXPERT OPINION: Although there has been increased recognition both clinically and in the medical literature, there is still a general lack of knowledge of PH and its clinical features in the medical community. An improved understanding of the underlying pathophysiology as well as more available commercial testis, such as ELISA that accurately measures specific IgE to progesterone, are expected to broaden and improve opportunities for disease recognition and symptom control. It is essential for physicians across specialties to recognize how to diagnose PH and either manage this condition or refer these patients to a specialist with experience treating PH.

Epidemiology, clinical profile, management, and outcome of COVID-19-associated rhino-orbital-cerebral mucormycosis in 2826 patients in India - Collaborative OPAI-IJO Study on Mucormycosis in COVID-19 (COSMIC), Report 1.

Purpose: COVID-19-associated rhino-orbital-cerebral mucormycosis (ROCM) has reached epidemic proportion during India's second wave of COVID-19 pandemic, with several risk factors being implicated in its pathogenesis. This study aimed to determine the patient demographics, risk factors including comorbidities, and medications used to treat COVID-19, presenting symptoms and signs, and the outcome of management. Methods: This was a retrospective, observational study of patients with COVID-19-associated ROCM managed or co-managed by ophthalmologists in India from January 1, 2020 to May 26, 2021. Results: Of the 2826 patients, the states of Gujarat (22%) and Maharashtra (21%) reported the highest number of ROCM. The mean age of patients was 51.9 years with a male preponderance (71%). While 57% of the patients needed oxygen support for COVID-19 infection, 87% of the patients were treated with corticosteroids, (21% for > 10 days). Diabetes mellitus (DM) was present in 78% of all patients. Most of the cases showed onset of symptoms of ROCM between day 10 and day 15 from the diagnosis of COVID-19, 56% developed within 14 days after COVID-19 diagnosis, while 44% had delayed onset beyond 14 days. Orbit was involved in 72% of patients, with stage 3c forming the bulk (27%). Overall treatment included intravenous amphotericin B in 73%, functional endoscopic sinus surgery (FESS)/paranasal sinus (PNS) debridement in 56%, orbital exenteration in 15%, and both FESS/PNS debridement and orbital exenteration in 17%. Intraorbital injection of amphotericin B was administered in 22%. At final follow-up, mortality was 14%. Disease stage >3b had poorer prognosis. Paranasal sinus debridement and orbital exenteration reduced the mortality rate from 52% to 39% in patients with stage 4 disease with intracranial extension (p < 0.05). Conclusion: : Corticosteroids and DM are the most important predisposing factors in the development of COVID-19-associated ROCM. COVID-19 patients must be followed up beyond recovery. Awareness of red flag symptoms and signs, high index of clinical suspicion, prompt diagnosis, and early initiation of treatment with amphotericin B, aggressive surgical debridement of the PNS, and orbital exenteration, where indicated, are essential for successful outcome.
