A Review of the Impact of Maternal Prenatal Stress on Offspring Microbiota and Metabolites.

Maternal prenatal stress exposure affects the development of offspring. We searched for articles in the PubMed database and reviewed the evidence for how prenatal stress alters the composition of the microbiome, the production of microbial-derived metabolites, and regulates microbiome-induced behavioral changes in the offspring. The gut-brain signaling axis has gained considerable attention in recent years and provides insights into the microbial dysfunction in several metabolic disorders. Here, we reviewed evidence from human studies and animal models to discuss how maternal stress can modulate the offspring microbiome. We will discuss how probiotic supplementation has a profound effect on the stress response, the production of short chain fatty acids (SCFAs), and how psychobiotics are emerging as novel therapeutic targets. Finally, we highlight the potential molecular mechanisms by which the effects of stress are transmitted to the offspring and discuss how the mitigation of early-life stress as a risk factor can improve the birth outcomes.

Dancing with paper

The exhibition also includes colour photographs of dancers taken at their homes by visual artist Sara Hibbert, and a film documentary about the project directed by Teale and Skapin. Hibbert says that, by cropping her colour photographs of dancers' hands and limbs, her final exhibited images “explore the notion of shared space, of presence becoming visible within the gaps, of collective timing and exchange”. The exhibition provides illuminating glimpses into the creative processes of dance and visual art.

Alcohol Consumption during the COVID-19 Lockdown Period: Predictors of At-Risk Drinking at Different AUDIT-C Cut-Off Thresholds.

During the COVID-19 pandemic, alcohol consumption was largely confined to drinking in the home. There has been little research examining variables associated with risk in home drinking. The study employed an online survey of (n = 1128) individuals who had been recruited for their face recognition skills (n = 838, 70.9% females, mean age 45.05 (12.3 SD)). The main dependent variables were three different AUDIT-C cut-off scores for at-risk drinking: (a) 5 for both genders as recommended by Public Health England, (b) 7 for females and 8 for males (cut-off for students and young people) and (c) 8 for both genders (individuals seeking online help for their drinking). Among the independent variables were gender and age, motivations for home drinking using the Home Drinking Assessment Scale (HDAS), purchasing patterns, context of drinking and health and wellbeing. The predictors following hierarchical logistic regressions were for (a) purchasing alcohol online or at a supermarket and emotional HDAS scores, (b) purchasing alcohol online or at a supermarket and for parties, drinking alone and with other members of the household and emotional and practical reason HDAS scores, (c) as for b with the addition that men were more likely to be at-risk drinkers. At-risk drinking in the pandemic was explained by motivational reasons, purchasing patterns and situational factors.

Perforated Appendicitis During a Pandemic: The Downstream Effect of COVID-19 in Children.

INTRODUCTION: Coronavirus Disease-19 (COVID-19) was declared a pandemic in March 2020. States issued stay-at-home orders and hospitals cancelled non-emergent surgeries. During this time, we anecdotally noticed more admissions for perforated appendicitis. Therefore, we hypothesized that during the months following the COVID-19 pandemic declaration, more children were presenting with perforated appendicitis. MATERIALS AND METHODS: This is a retrospective cohort study reviewing pediatric patients admitted at a single institution with acute and/or perforated appendicitis between October 2019 to May 2020. Interval appendectomies were excluded. COVID-19 months were designated as March, April, and May 2020. Additional analysis of March, April, and May 2019 was performed for comparison purposes. Analyzed data included demographics, symptoms, white blood cell count, imaging findings, procedures performed, and perforation status. Statistical analysis was performed. RESULTS: During the study period, 285 patients were admitted with the diagnosis of acute appendicitis with 95 patients being perforated. We identified a significant increase in perforated appendicitis cases in the three COVID-19 months compared with the preceding five months (45.6% vs 26.4%; P <0.001). In addition, a similar significant increase was identified when comparing to the same months a year prior (P = 0.003). No significant difference in duration of pain was identified (P=0.926). CONCLUSION: The COVID-19 pandemic and its associated stay-at-home orders have had downstream effects on healthcare. Our review has demonstrated a significant increase in the number of children presenting with perforated appendicitis following these stay-at-home ordinances. These results demonstrate that further investigations into the issues surrounding access to healthcare, especially during this pandemic, are warranted.

Effect of the COVID-19 Pandemic on Pediatric Intestinal Failure Healthcare Delivery.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has influenced how healthcare is being provided, particularly in patients whose diagnoses require multidisciplinary care, such as pediatric intestinal failure (IF). We sought to ascertain the effects of the COVID-19 pandemic on healthcare delivery for pediatric patients with IF. METHODS: A 20-question survey was administered to members of the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition Intestinal Rehabilitation (IR) Special Interest Group. Input values were "yes" and "no," along with a free-text response. Following a 10-day open survey period, data were divided into cohorts based on patient population size and disease burden by state. Analysis was then performed using the χ2 test application. RESULTS: Responses from 29 centers were included in analysis. Centers that followed >50 patients on parenteral nutrition (PN) were more likely to have social workers present in telemedicine visits and observed more central line difficulties among families. Centers located in states with <40,000 reported cases of COVID-19 saw patients less frequently and were more likely to withhold changes to PN prescriptions. Additionally, the survey revealed a significant degree of financial hardship and food insecurity among families. CONCLUSION: Many aspects of pediatric IF healthcare delivery have been impacted by the COVID-19 pandemic, both for care providers and caregivers. Despite the availability of telemedicine, IR centers should remain attentive to the global needs of the pediatric IF patient, as well as their families.
