Barnyard millet () is a nutritionally superior grain and a rich source of dietary fiber, and protein. It helps in managing health and dietary issues such as malnutrition, diabetes, obesity, and celiac disease. Its low content of slowly digestible carbohydrates promotes a gradual release of glucose, helping to maintain stable blood glucose levels.

Aims/hypothesis: Accurate understanding of type 1 diabetes risk is critical for optimisation of counselling, monitoring and interventions, yet even within established staging classifications, individual time to clinical disease varies. Previous work has associated IA-2A positivity with increased type 1 diabetes progression but a comprehensive assessment of the impact of screening for IA-2A positivity across the natural history of autoantibody positivity has not been performed. We asked whether IA-2A would consistently be associated with higher risk of progression within and across established stages of type 1 diabetes in a large natural history study.

Antibiotics, the full-stop of invasive bacteria, have been used in clinical setups from unthreatening fever to massive challenging therapies. Constant dependency on medication upsurges the evasion of microbes from antibiotics contemporarily along with ecological footprint. Thus, the infested pathogen became resilient to antibiotics, disguised as multidrug-resistant bacteria (MDR), pandrug-resistant bacteria (PDR), and extensively drug-resistant bacteria (XDR).

Exploring the complex world of microRNA (miRNA) biogenesis and functions in plants is essential for understanding their diverse regulatory mechanisms. This review highlights the processes involved in miRNA biogenesis and their crucial roles in growth and development of plant, stress responses, and nutrient homeostasis. miRNAs play a central role in various developmental processes, including the transition from the juvenile to adult stage, the growth of shoot apical meristem, leaf and floral morphogenesis, and the determination of flowering time.

Autism spectrum disorder (ASD) occurs within all racial, ethnic, and demographic pediatric groups. However, Black children with ASD are diagnosed at later stages of their development, and as a result may not receive or may age out of early intervention services, and demonstrate poorer long-term outcomes, across a range of factors. African American parent's perceptions regarding access to and utilization of healthcare services for their autistic children vary.

Article Synopsis
  • The study investigated a glucose fraction that operates independently of insulin secretion in individuals positive for diabetes-related autoantibodies.
  • It utilized data from two major trials, analyzing the relationship between the glucose response and insulin levels through linear regression.
  • Findings revealed that this independent glucose fraction (iAUCGLU) significantly contributes to the rise in blood sugar levels in impaired glucose tolerance and is a stronger predictor for this condition than for type 1 diabetes (T1D).

Aims/hypothesis: We aimed to analyse TrialNet Anti-CD3 Prevention (TN10) data using oral minimal model (OMM)-derived indices to characterise the natural history of stage 2 type 1 diabetes in placebo-treated individuals, to describe early metabolic responses to teplizumab and to explore the predictive capacity of OMM measures for disease-free survival rate.

Methods: OMM-estimated insulin secretion, sensitivity and clearance and the disposition index were evaluated at baseline and at 3, 6 and 12 months post randomisation in placebo- and teplizumab-treated groups, and, within each group, in slow- and rapid-progressors (time to stage 3 disease >2 or 2 years). OMM metrics were also compared with the standard AUC C-peptide.

One-and-a-half syndrome (OHS) is a horizontal gaze palsy in one direction with internuclear ophthalmoplegia (INO) in the other. The only eye movement possible is the abduction of the contralateral eye with nystagmus. The usual structures affected are the medial longitudinal fasciculus and paramedian pontine reticular formation or the abducens nucleus.

Context: Metabolic measures are frequently used to predict type 1 diabetes (T1D) and to understand effects of disease-modifying therapies.

Objective: Compare metabolic endpoints for their ability to detect preventive treatment effects and predict T1D.

Methods: Six-month changes in metabolic endpoints were assessed for (1) detecting treatment effects by comparing placebo and treatment arms from the randomized controlled teplizumab prevention trial, a multicenter clinical trial investigating 14-day intravenous teplizumab infusion and (2) predicting T1D in the TrialNet Pathway to Prevention natural history study.

Background: Despite advances in parenteral nutrition, postnatal growth failure in very low birthweight (VLBW) preterm infants is common and associated with chronic health problems. Insulin-like growth factor 1 (IGF-1) is positively associated with improved infant growth, but factors which promote IGF-1 levels in this population have not been clearly identified. The objective of this study was to explore early factors that influence IGF-1 in VLBW preterm infants.

Article Synopsis
  • A study was conducted in India to investigate sudden unexplained deaths among healthy young adults (ages 18-45) possibly linked to COVID-19 infection or vaccination from October 2021 to March 2023.
  • The research analyzed data from 729 cases and 2,916 matching controls, assessing factors like COVID-19 vaccination status, family history, substance use, and physical activity.
  • Results indicated that receiving at least one COVID-19 vaccine dose reduced the likelihood of sudden death, while factors such as past hospitalization for COVID-19, family history of sudden deaths, binge drinking, and intense physical activity increased the risk.

Background: Vascular calcifications are a hallmark of atherosclerosis, and in the coronary arteries are routinely used as a prognostic marker. Calcifications of intracranial vessels (ICC) are frequently observed on non-contrast CT (NCCT) and their effect on post-stroke cognitive impairment (PSCI) remains unclear. Our aim was to explore the association of ICC with prospective long-term cognitive function and advanced MRI-measures in a large prospective cohort of cognitively intact mild stroke survivors.

Pneumomediastinum can be primary (spontaneous) or secondary to iatrogenic, traumatic, and non-traumatic causes. The incidence of spontaneous and secondary pneumomediastinum is higher in patients with coronavirus disease 2019 (COVID-19) compared to the general population. So, pneumomediastinum should be considered in the differential diagnosis of any patient with COVID-19 presenting with chest pain and breathlessness.
