Ready-to-use supplemental foods (RUSF) are energy-dense meals formulated to prevent and treat moderate and severe childhood acute malnutrition (MAM and SAM) in high-risk settings. Although lifesaving, the degree and durability of weight recovery with RUSF is unpredictable. We examined whether environmental enteric dysfunction (EED) and gut microbiota perturbations are risk factors for RUSF failure in a birth cohort of 416 rural Pakistani children followed for growth, common childhood illnesses, and biomarkers from blood, urine, and stool.

: pathogenic variant (PV)-associated breast cancers are most commonly seen in hereditary genetic conditions such as the autosomal-dominant Hereditary Breast and Ovarian Cancer (HBOC) syndrome, and rarely in sporadic breast cancer. Such breast cancers tend to exhibit greater aggressiveness and poorer prognoses due to the influence of pathogenic variants (PVs) on the tumour microenvironment. Additionally, while the genetic basis of PV breast cancer is well-studied, the role of epigenetic mediators in the tumourigenesis of these hereditary breast cancers is also worth exploring.

A significant proportion of patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI) have concomitant coronary artery disease (CAD). The best way to treat these patients is contentious. Conventional assessments of ischaemia such as fractional flow reserve (FFR) and instantaneous wave-free ratio are not validated in the context of severe AS despite having a Class I European Society of Cardiology indication in patients with isolated coronary disease.

Article Synopsis
  • This study looks at how traumatic stress affects gene expression in specific areas of the brain (the mPFC) linked to neuropsychiatric disorders like PTSD and anxiety disorders.* -
  • Using an animal model of stress, researchers found 62 genes that were expressed differently in the brain areas studied, with each area showing unique patterns related to functions like synapse formation and neuronal activity.* -
  • The findings suggest that certain pathways related to neurodegeneration and stress signaling may play a role in how individuals respond to trauma, highlighting potential areas for further research and treatment.*

Background: This study compares Selective Amygdalohippocampectomy (SAHE) and Anterior Temporal Lobectomy (ATL) for temporal lobe epilepsy (TLE), focusing on seizure control and visual field deficits (VFD). While previous research suggests potential benefits of SAHE, this meta-analysis aims to clarify the comparative effectiveness of bothprocedures.

Methods: This study adhered to PRISMA guidelines, comparing seizure outcomes and VFDs between SAHE and ATL for temporal lobe epilepsy.

Type I Diabetes is an endocrine disorder that prevents the pancreas from regulating the blood glucose (BG) levels in a patient's body. The ubiquitous Linear-Quadratic-Integral-Regulator (LQIR) is an optimal glycemic regulation strategy; however, it is not resilient enough to withstand measurement noise and meal disruptions. The Sliding-Mode-Controller (SMC) yields robust BG regulation effort at the expense of a discontinuous insulin infusion rate that perturbs the BG concentrations.

Carbonic anhydrase IX (CA IX), upregulated by hypoxia-inducible factor (HIF), plays a crucial role in regulation of intracellular and extracellular pH, which is essential for the growth and spread of tumors. The overexpression of CA IX in breast cancer is linked to a low post-radiation patient survival rate. Under normoxic conditions, CA IX expression is relatively low, but hypoxia-inducible factors (HIFs) upregulate its expression when oxygen levels drop.

Electrochemical water splitting is a promising approach towards a sustainable and renewable energy source. However, the demand for high anodic potential and sluggish kinetics of oxygen evolution reaction (OER) restrict the efficiency and feasibility of the water-splitting process. In this quest, transition metal oxides and alloys are considered potential candidates owing to their natural occurrence and high redox potential for OER.

Peripheral T-cell lymphoma (PTCL) is a heterogeneous group of neoplasms, with many cases remaining unclassifiable and categorized as PTCL-not otherwise specified (PTCL-NOS). Gene expression profiling (GEP) has delineated 2 prognostic subtypes within PTCL-NOS, PTCL-TBX21 and PTCL-GATA3, characterized by distinctive transcriptomes and a different prognosis. To further evaluate the pathologic features of these subgroups, 101 PTCL cases that did not meet specific criteria for well-defined T-cell lymphoma entities underwent detailed pathologic, immunophenotypic (including T follicular helper [T] biomarkers), and GEP analyses, separating them into PTCL-NOS (n = 63) and PTCL-TFH (also known as nodal PTCL-TFH, NOS, and TFH lymphoma, NOS) (n = 38).
