The role of the gut microbiome in the Gut-Brain Axis and modulation of neuropsychiatric disease is increasingly recognized. The role of antenatal diet, particularly fiber intake, in mitigating maternal mental health disorders remains unexplored.

Little is known about the time course of muscle-bone effects and whether a reciprocal clinical effect of bone on muscle is present. We hypothesized that lean mass (LM) measures at the arms and legs have a stronger relationship with BMD measured within the same region than the reciprocal effect. The Tobago Bone Health Study was used to address this hypothesis, examining body composition data from total body DXA scans obtained at 0, 48-, and 120-month visits.

We determined the frequency and factors associated with the first clinical relapse after immunomodulator (IM) withdrawal in a cohort of children with inflammatory bowel disease on combination therapy. A total of 105 patients (89 with Crohn disease [CD]) in clinical remission were included (91 [86.7%] were on infliximab, 53 [50.

Objective: This prospective observational study aimed to examine the prevalence of obesity in a population-based cohort of children and young adults newly diagnosed with inflammatory bowel disease (IBD) and assess their outcome in comparison to newly diagnosed normal/underweight patients.

Methods: Our longitudinal population-based cohort comprised all children younger than 17 years diagnosed with IBD in the province of Manitoba, Canada between 2012 and 2018. Cox regression model with adjustment for a priori covariates was used to examine the time to first relapse among patients who were obese/overweight at the time of IBD diagnosis in comparison to patients who were normal or underweight.

Background: The study's objective was to investigate the incidence and risk factors associated with Clostridioides difficile (previously known as Clostridium) infection (CDI) in children with inflammatory bowel disease (IBD) in the province of Manitoba.

Methods: Our longitudinal population-based cohort was comprised of all children and young adults aged <17 years diagnosed with IBD in the Canadian province of Manitoba between 2011 and 2019. The diagnosis of CDI was confirmed based on the Triage C.

Bone and muscle have shown to interact, but little is known about fat within bone and muscle. Clinical studies have isolated fat within bone and muscle using MRI. In this cross-sectional study, we hypothesized that bone marrow adiposity and muscle adiposity are related and that this relationship is associated with osteoporosis.

Objective: To assess the characteristics of inflammatory bowel disease and disease prognosis among children with elevated gamma glutamyltransferase (GGT) and primary sclerosing cholangitis (PSC)-ulcerative colitis (UC).

Study Design: Our longitudinal, population-based cohort comprised all children and young adults diagnosed with UC in the Canadian province of Manitoba between 2011 and 2018. Diagnosis of PSC was confirmed based on a combination of cholestatic biochemical markers and cholangiographic features.

Objective: Although anti-Saccharomyces cerevisiae antibodies (ASCAs) could be a useful biomarker in differentiating Crohn disease (CD) from ulcerative colitis (UC), their role as prognostic markers in children with CD has been underinvestigated. This longitudinal prospective observational study aimed to assess the prognostic value of ASCA status among children with CD managed using biologics.

Methods: The study population comprised children with inflammatory bowel disease diagnosed with CD from 2012 to 2018.

Article Synopsis
  • Wernicke-Korsakoff syndrome (WKS) includes Wernicke encephalopathy and Korsakoff psychosis, both linked to thiamine deficiency, which affects the body's ability to utilize carbohydrates.
  • Thiamine deficiency can arise from genetic factors or conditions like alcoholism and often leads to symptoms that are similar to other neurological disorders, making WKS difficult to diagnose.
  • Timely diagnosis and treatment of Wernicke encephalopathy are crucial to prevent the severe memory loss associated with Korsakoff psychosis, and this review highlights research on the causes, identification, and treatment options for these conditions.

Barth Syndrome (BTHS) is a rare X-linked genetic disease in which the specific biochemical deficit is a reduction in the mitochondrial phospholipid cardiolipin (CL) as a result of a mutation in the CL transacylase tafazzin. We compared the phosphokinome profile in Epstein-Barr-virus-transformed lymphoblasts prepared from a BTHS patient with that of an age-matched control individual. As expected, mass spectrometry analysis revealed a significant (>90%) reduction in CL in BTHS lymphoblasts compared to controls.

Article Synopsis
  • The PAR-1-MARK pathway regulates cell polarity by phosphorylating microtubule-associated proteins, specifically ARHGEF2.
  • Liver kinase B1 (LKB1) activates MARK3, leading to the phosphorylation of ARHGEF2, which disrupts its binding to DYNLT1 and promotes RHOA activation.
  • This phosphorylation is crucial for forming stress fibers and maintaining organized cellular structures, highlighting a regulatory mechanism that connects microtubules and the actin cytoskeleton in epithelial cells.

  • VTE, which includes deep vein thrombosis and pulmonary embolism, poses substantial risks during general surgeries, yet is frequently neglected.
  • A year-long study assessed 400 surgical patients to determine the prevalence of VTE, bleeding risk factors, and the sufficiency of thromboprophylaxis, revealing that 41% were at high risk and only 28% received proper prophylaxis.
  • The findings indicate the need for improved thromboprophylaxis strategies, such as forming a multidisciplinary team to enhance patient care and outcomes.

Introduction: The recent outbreaks of Hepatitis A in Kerala are suggestive of decrease in endemicity as most adults were not exposed during the childhood. In allopathic system of medicine, there is no established treatment for Hepatitis A and hence most people tend to rely on the alternate systems of medicine. The study was aimed at identifying the burden of Hepatitis A in the locality and to uncover the degree of dependence of the people on traditional systems of medicine.

Background: The widespread misuse of antibiotics over the past several decades has been regarded as the contributing factor in the development of resistance toward them. Extended spectrum β-lactamases (ESBLs) are enzymes produced by certain bacteria that can make them resistant to certain antibiotics. Early detection of ESBL strains and judicious use of antibiotics and proper implementation of infection control strategies are essential to prevent the spread of this threat in the community.
