Background: Insulin resistance (IR) is an important risk factor for multiple chronic diseases, increasing mortality and reducing life expectancy. The associations between emerging surrogates for IR, triglyceride-glucose index (TyG) and TyG-related indicators, with all-cause mortality and life expectancy in middle-aged and older patients in primary care are unclear.

Methods: This study originated from the Polish primary care cohort LIPIDOGRAM2015, including patients aged ≥45 years.

RET signalling in the pituitary: a double-edged sword for differentiation, apoptosis and therapeutic strategies in acromegaly.

Endocr Relat Cancer

January 2025

C Alvarez, Centro de Investigación en Medicina Molecular y Enfermedades Crónicas (CIMUS), University of Santiago de Compostela (USC), Santiago de Compostela, Spain.

The discovery of RET mutations in Multiple Endocrine Neoplasia 2A (MEN2A) in 1993 ignited a revolution in our understanding of this versatile receptor. Since then, RET's influence has expanded to encompass diverse organs, including the pituitary gland. This review explores the multifaceted role of RET in somatotrophs, focusing on two opposing pathways: proliferation versus differentiation and apoptosis.

Objective: Hyponatremia after aneurysmal subarachnoid hemorrhage (aSAH) is common, however the incidence, and association with vasospasm, morbidity, and mortality, has yet to be defined. We aimed to identify incidence of hyponatremia after aSAH, and quantify its association with measurable outcomes.

Methods: A PRISMA-compliant systematic review and meta-analysis was conducted (PROSPERO ID CRD42022363472).

Connective tissue disease associated pulmonary arterial hypertension (CTD-PAH) has benefited from the major treatment advances that have occurred within pulmonary hypertension over the past three decades. Inclusion of CTD-PAH cases in pivotal clinical trials led to regulatory approval and drug availability. This has improved outcomes but there are additional challenges for management.

Purpose: While traditional theories suggest a link between language lateralization and handedness, recent evidence indicates more complex neural networks underlying speech processing. This study aimed to investigate the involvement of the left and right hemispheres in speech production using repetitive transcranial magnetic stimulation (rTMS).

Methods: A cohort of 58 healthy volunteers with a median age of 23 (range 19-34) were included in the study.

Background And Hypothesis: In chronic kidney disease (CKD) the nitric oxide (NO)-soluble guanylate cyclase (sGC)-cyclic guanosine monophosphate (cGMP) pathway is impaired. Runcaciguat, an sGC activator, activates heme-free sGC, restoring cGMP production. This phase 2a trial studied the efficacy, safety, and tolerability of runcaciguat in CKD patients with or without sodium-glucose co-transporter-2 inhibitor (SGLT2i).

Introduction: Classical risk factors such as hypertension, hypercholesterolemia, pre-diabetes, diabetes and obesity can predict adverse cardiovascular events, but they are less prognostic in patients aged < 60 years. Polygenic risk scores (PRS) can be effective in predicting adverse coronary events in younger and middle-aged patients. Our main aim is to assess the utility of a new PRS created for the Polish population in predicting mortality during an 8-year follow-up in the nationwide LIPIDOGEN2015 population.

Introduction: Chronic ocular hypotony (low intraocular pressure (IOP)) is a potentially sight-threatening condition. Although there is some controversy as to what constitutes non-physiological IOP, generally it is accepted as an IOP of 6.5 mm Hg or less, measured on three separate occasions and lasting for at least 3 months.

Article Synopsis
  • This review analyzes various mammography datasets used for AI development in breast cancer screening, focusing on their transparency, content, and accessibility.
  • A search identified 254 datasets, with only 28 being accessible; most datasets came from Europe, East Asia, and North America, raising concerns over poor demographic representation.
  • The findings highlight significant gaps in diversity within these datasets, underscoring the need for better documentation and inclusivity to enhance the effectiveness of AI technologies in breast cancer research.

A 72-year-old man presented to his general practitioner with worsening dyspnea and was diagnosed with having recurrent -positive stage IIIB NSCLC 8 years after initial diagnosis and radical treatment for early stage disease. He was subsequently started on entrectinib but required hospital admissions for recurrent acute kidney injuries on a background of chronic kidney disease. His entrectinib was withheld on day 20 since his first dose of treatment while he was being investigated.

Atopic dermatitis (AD) is a chronic, inflammatory skin condition which affects over 200 million people worldwide, with patients commonly presenting with dry, itchy and sore skin. The challenge in finding optimal treatment for AD stems from the heterogenous nature of the disease and its multifaceted aetiology: skin barrier dysfunction, immune system dysregulation, genetic factors, environmental factors and alterations in skin microorganisms. Traditional treatments for AD such as corticosteroids, calcineurin inhibitors and immunosuppressants have several limitations such as reoccurrence of symptoms when discontinued, lack of targeted action and risk of adverse effects.

Hypertension is a major risk factor for peripheral arterial atherosclerotic disease (PAD). Hypertension deteriorates arterial wall function and the morphology of all layers of arteries. Endothelial cell injury enhances permeability and promotes migration of cholesterol and monocytes into the vessel wall.

It had long been considered that no new neurons are generated in the primate brain beyond birth, but recent studies have indicated that neurogenesis persists in various locations throughout the lifespan. The dentate gyrus of the hippocampus is of particular interest due to the postulated role played by neurogenesis in memory. However, studies investigating the presence of adult hippocampal neurogenesis (AHN) have reported contradictory findings, and no systematic review of the evidence has been conducted to date.

Patient satisfaction using wide-awake local anaesthesia no tourniquet (WALANT) in adults undergoing elective hand surgery: A systematic review and meta-analysis.

J Plast Reconstr Aesthet Surg

December 2024

Department of Plastic and Reconstructive Surgery, Royal Free London NHS Foundation Trust, London, United Kingdom.

Background: Wide-awake local anaesthesia no tourniquet (WALANT) is increasing in popularity within hand surgery. However, evidence is unclear on patient satisfaction rates when WALANT is compared against more traditional anaesthetic techniques where pneumatic tourniquets are used. The present study aimed to evaluate the satisfaction rates of patient with the WALANT technique.
