Article Synopsis
  • Cardiovascular disease (CVD) significantly affects people living with HIV (PLWH), with this study finding a diagnosed CVD prevalence of 10.8% among 1425 participants aged 40-75.
  • The assessment utilized five different risk evaluation tools, revealing that 42.8% of participants had a high 10-year risk of CVD, while 71.7% were classified as high- to very high-risk using the SCORE2 tool.
  • The findings stress the need for better cardiovascular health monitoring and highlighted that current utilization of lipid-lowering therapy is inadequate, despite a large number of PLWH being eligible for such treatment per recent guidelines.

The Effects of IGF1 and MGF on Neural Stem Cells in Hypoxic Conditions.

Basic Clin Neurosci

May 2024

Department of Genetics, Aziz Sancar Research Institute of Experimental Medicine, Iıstanbul University, Çapa Campus, Iıstanbul, Turkey.

Article Synopsis
  • Ischemic stroke leads to high rates of illness and death globally, with low oxygen levels making neural stem cells (NSC) more susceptible to injury; this study examines the effects of insulin-like growth factor 1 (IGF-I) and mechano growth factor (MGF) on NSCs under low oxygen conditions.
  • An in vitro model using rat hippocampal NSCs exposed to varying oxygen levels showed that low oxygen increased specific gene expressions, with IGF-I downregulating hypoxia-inducible factor (HIF1-α) while MGF improved NSC proliferation across all oxygen scenarios.
  • Findings suggest that both IGF-I and MGF enhance NSC proliferation and may have potential therapeutic roles in

Background: The aim of this study is to determine whether there are any changes in hemorheological parameters, including whole blood viscosity (WBV), plasma viscosity, erythrocyte aggregation, and erythrocyte deformability, in acute ischemic stroke patients, and to establish their relationship with stroke etiology. The study also aims to observe the changes in these parameters, if any, over time and after treatment, and to assess the correlation between risk factors for ischemic stroke and neuroimaging findings.

Methods: This was a prospective observational study including 70 patients diagnosed with acute ischemic stroke within the first 3 days of the onset of symptoms and 96 healthy controls.

Purpose: The aim of this study is to investigate the effect of vitreomacular interface disorders (VMID) on treatment response in patients treated with anti-vascular endothelial growth factor (anti-VEGF) due to diabetic macular edema (DME).

Methods: Three hundred seventy-seven eyes of 239 patients in the MARMASIA Study Group who received intravitreal anti-VEGF treatment (IVT) due to DME were included in the study. The group 1 consisted of 44 eyes of the patients who had not received any treatment before, were followed up regularly for 24 months after at least a 3-month loading dose, and suffered from VMID such as epiretinal membrane, vitreomacular adhesion or traction, and lamellar hole.

Introduction: Sarcopenia, characterized by progressive skeletal muscle loss, has emerged as a significant public health concern, with a global prevalence of 10-27%. While traditionally studied in geriatric populations, recent evidence indicates its impact on individuals aged 40 and above, with early manifestations of muscle decline. Primary care settings play a pivotal role in the early identification and management of sarcopenia, facilitating timely diagnosis and intervention.

Purpose: This study aimed to compare the effect of intravitreal aflibercept (IVA) and ranibizumab (IVR) on the maximal diameter of the largest intraretinal cyst (mdIRC), indicating chronicity in patients with diabetic cystoid macular edema (CME).

Methods: This retrospective, comparative study included a subgroup of patients from the MARMASIA Study with treatment-naïve diabetic CME who had IVA (IVA group) or IVR (IVR group) on a pro re nata regimen after a loading dose of 3-monthly injections and followed-up for 24 months. Best-corrected visual acuity (logMAR), central macular thickness (CMT, µm), and mdIRC (µm) and their changes during the study period in the IVA and IVR groups were compared.

Predictors of relapse risk and treatment response in AQP4-IgG positive and seronegative NMOSD: A multicentre study.

J Neurol Neurosurg Psychiatry

September 2024

Department of Neuroscience, School of Translational Medicine, Monash University, Melbourne, Victoria, Australia

Background: Neuromyelitis optica spectrum disorder (NMOSD) can be categorised into aquaporin-4 antibody (AQP4-IgG) NMOSD or seronegative NMOSD. While our knowledge of AQP4-IgG NMOSD has evolved significantly in the past decade, seronegative NMOSD remains less understood. This study aimed to evaluate the predictors of relapses and treatment responses in AQP4-IgG NMOSD and seronegative NMOSD.

Objective: In the hepatitis C virus (HCV) diagnostic algorithm, an anti-HCV screening test is recommended first. In countries with low HCV prevalence, anti-HCV testing can often give false-positive results. This may lead to unnecessary retesting, increased costs, and psychological stress for patients.

Article Synopsis
  • The study aimed to assess the thickness of the conjunctival/episcleral tissue and the anterior sclera in keratoconus patients wearing mini-scleral contact lenses using AS-OCT technology.
  • Results showed that keratoconus patients using contact lenses had significantly thinner conjunctival/episcleral tissue compared to those not wearing lenses and healthy controls, particularly in the superior and inferior regions.
  • Overall, while mini-scleral lens wear led to thinning of the conjunctiva/episclera, it did not affect the thickness of the sclera, highlighting AS-OCT's usefulness for evaluating contact lens impacts.
