Lifestyle and Pharmacologic Approaches to Prevention of MASLD-related HCC.

Hepatocellular carcinoma (HCC) is a major concern for public health. Fatty liver disease, related to alcohol misuse or metabolic syndrome, has become the leading cause of chronic liver disease and HCC. The strong association between type 2 diabetes mellitus and HCC can be partly attributed to the development of metabolic dysfunction associated steatotic liver disease (MASLD).

Markedly elevated citrulline in a neonate: Citrin deficiency due to a previously unreported SLC25A13 variant.

Background: Citrin deficiency (CD) is an autosomal recessive metabolic disorder affecting the urea cycle and energy production. Diagnosis involves measuring ammonia, amino acid levels (eg: citrulline), with confirmation through solute carrier family 25 member 13 (SLC25A13) gene mutation analysis. Herein, we present a case report of a variant in the SLC25A13 gene that has not been previously reported in the literature.

Outcomes of Extremely Preterm Infants Exposed to Prolonged Prelabor Rupture of Membranes before 24 Weeks of Gestation.

Background: Preterm prelabor rupture of membranes (PPROM) before or around the limit of fetal viability is associated with serious maternal and neonatal complications including chorioamnionitis, extremely preterm birth, and pulmonary hypoplasia.

Objectives: To describe contemporary outcomes of extremely preterm infants born after prolonged periviable PPROM, and to identify perinatal factors associated with survival and survival without severe neurodevelopmental impairment (NDI).

Study Design: Among actively treated infants born alive at <27 weeks' gestational age (GA) in centers of the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network from 2012 to 2018, the outcomes of survival and survival without severe NDI at 22-26 months' corrected age were compared between infants exposed to prolonged (≥120 hours) periviable (<24 weeks' GA) PPROM and unexposed infants born after rupture of membranes ≤18 hours before delivery or at delivery, adjusting for birth GA, sex, multiple gestation, antenatal steroids, small for gestational age (SGA), insurance, and center.

Aim of this systematic review is to update ERAS recommendations for patients undergoing RC and to give an expert opinion on the relevance of each single ERAS item.

Methods: A systematic review was performed to identify the impact of each single ERAS item on RC outcomes.

Use of continuous glucose monitoring and point-of-care glucose testing in hospitalized patients with diabetes mellitus in non-intensive care unit settings: A systematic review and meta-analysis of randomized controlled trials.

The benefits of using continuous glucose monitoring (CGM) in hospitalized patients with diabetes remain uncertain. Point-of-care (POC) glucose testing is the standard of care in this setting. We compared the effect of adding CGM to POC testing versus POC testing alone on glycemic outcomes in this population.

Factors Associated With Minority Patient Enrollment in a Gastric Cancer Biobank.

Introduction: Human tissue samples are essential for translational cancer research. However, less than 20% of current biobank and genomic samples were obtained from minority patients, which may lead to biased understanding of cancer biology. The objective of this study was to identify factors associated with patient enrollment in our institution's gastric cancer biobank.

However, the role of radioactive iodine (RAI) ablation in these patients remains uncertain. This investigation evaluates the national trends, therapeutic practices, and the impact of RAI on clinical outcomes.

Glutaminase-2 Expression Induces Metabolic Changes and Regulates Pyruvate Dehydrogenase Activity in Glioblastoma Cells.

Glutaminase controls the first step in glutaminolysis, impacting bioenergetics, biosynthesis and oxidative stress. Two isoenzymes exist in humans, GLS and GLS2. GLS is considered prooncogenic and overexpressed in many tumours, while GLS2 may act as prooncogenic or as a tumour suppressor.

Molecular Sentinels: Unveiling the Role of Sirtuins in Prostate Cancer Progression.

Prostate cancer (PCa) remains a critical global health challenge, with high mortality rates and significant heterogeneity, particularly in advanced stages. While early-stage PCa is often manageable with conventional treatments, metastatic PCa is notoriously resistant, highlighting an urgent need for precise biomarkers and innovative therapeutic strategies. This review focuses on the dualistic roles of sirtuins, a family of NAD+-dependent histone deacetylases, dissecting their unique contributions to tumor suppression or progression in PCa depending on the cellular context.

This systematic review aimed to identify and describe best practice for the intraoperative anesthetic management of patients undergoing emergent/urgent decompressive craniotomy or craniectomy for any indication. The PubMed, Scopus, EMBASE, and Cochrane databases were searched for articles related to urgent/emergent craniotomy/craniectomy for intracranial hypertension or brain herniation. Only articles focusing on intraoperative anesthetic management were included; those investigating surgical or intensive care unit management were excluded.

A lever hypothesis for Synaptotagmin-1 action in neurotransmitter release.

Neurotransmitter release is triggered in microseconds by Ca-binding to the Synaptotagmin-1 C-domains and by SNARE complexes that form four-helix bundles between synaptic vesicles and plasma membranes, but the coupling mechanism between Ca-sensing and membrane fusion is unknown. Release requires extension of SNARE helices into juxtamembrane linkers that precede transmembrane regions (linker zippering) and binding of the Synaptotagmin-1 CB domain to SNARE complexes through a "primary interface" comprising two regions (I and II). The Synaptotagmin-1 Ca-binding loops were believed to accelerate membrane fusion by inducing membrane curvature, perturbing lipid bilayers, or helping bridge the membranes, but SNARE complex binding through the primary interface orients the Ca-binding loops away from the fusion site, hindering these putative activities.

Morphogen-induced kinase condensates transduce Hh signal by allosterically activating Gli.

Hedgehog (Hh) morphogen governs embryonic development and tissue homeostasis through the Ci/Gli family transcription factors. Here we report that Hh induces phase separation of the fused (Fu)/Ulk family kinases to allosterically regulate Ci/Gli. We find that Hh-induced phosphorylation of Fu/Ulk3 promotes SUMOylation of their inverted phosphorylation-dependent SUMOylation motifs.

Obesity reshapes regulatory T cells in the visceral adipose tissue by disrupting cellular cholesterol homeostasis.

Regulatory T cells (T) accumulate in the visceral adipose tissue (VAT) to maintain systemic metabolic homeostasis but decline during obesity. Here, we explored the metabolic pathways controlling the homeostasis, composition, and function of VAT T under normal and high-fat diet feeding conditions. We found that cholesterol metabolism was specifically up-regulated in ST2 VAT T subsets.
