Introduction: Although risk factors linked to diabetic retinopathy (DR) among patients with Type 2 diabetes mellitus (T2DM) have been extensively studied globally, the specific determinants of these factors in relation to DR in Palestine are presently not well understood.

Methods: This retrospective cross-sectional study included patients who underwent DR screening with a fundus camera (VersaCam a). The study included patients aged ≥18 with T2DM, excluding those with other types of diabetes or a history of malignancies.

Background: Differentiating between intrinsic and prerenal acute kidney injury (AKI) presents a challenge. Here, we assessed the performance of the fractional excretion of urea (FEUrea) and compared it to the fractional excretion of sodium (FENa) in distinguishing intrinsic from prerenal AKI.

Methods: A thorough search was conducted in several databases until January 16, 2024.

Article Synopsis
  • Secondary mitral regurgitation (MR) worsens in 10-15% of heart failure patients receiving cardiac resynchronization therapy (CRT), and transcatheter edge-to-edge repair (TEER) with Mitra-Clip shows promise in improving outcomes for those who are CRT non-responders.
  • A meta-analysis of 439 patients indicated that Mitra-Clip significantly reduced MR severity and improved symptoms in a majority of CRT non-responders within six months and one year post-procedure.
  • The mortality rates for patients after undergoing TEER with Mitra-Clip were similar to those observed in previous studies, with 30-day, 6-month, 1-year, and 2-year mortality rates at

Background And Aims: Genetic variants play a crucial role in the development of diabetic retinopathy (DR). Therefore, our study aimed to investigate the relationship between aldose reductase () (C106T) polymorphism with proliferative DR and associated risk factors in Palestinian type 2 diabetic patients.

Methods: A cross sectional study was conducted at St John Eye Hospital-East Jerusalem in 2020-2021 on patients with DR.

Objectives: This study aimed to investigate the association between systolic inter-arm blood pressure difference (IABPD) and the estimated glomerular filtration rate (eGFR), as well as chronic kidney disease (CKD), in patients with type 2 diabetes mellitus (T2DM).

Patients And Methods: This cross-sectional study included 189 Palestinians diagnosed with T2DM. Data were collected through personal interviews, medical records and three separate blood pressure measurements from both arms.

The clinical course and severity of COVID-19 vary among patients. This study aimed to investigate the potential correlation between the gene polymorphisms of the interferon receptor () rs2236757 and oligoadenylate synthetase 3 () rs10735079 with the risk of COVID-19 infection and its severity among Palestinian patients. The study was conducted between April and May 2021 on 154 participants who were divided into three groups: the control group (RT-PCR-negative,  = 52), the community cases group (RT-PCR-positive,  = 70), and the critically ill cases (ICU group;  = 32).

Background And Objectives: AKI is classified as prerenal, intrinsic, and postrenal. Prerenal AKI and intrinsic AKI represent the most common causes for AKI in hospitalized patients. This study aimed to examine the accuracy of the fractional excretion of sodium for distinguishing intrinsic from prerenal AKI.

Background: Genetic and environmental factors play a crucial role in the development of type 2 diabetes mellitus (T2DM) and obesity. This study aimed to investigate the association of the fat-mass and obesity-associated gene (FTO) rs9939609 variant with T2DM and body mass index (BMI) among Palestinian population.

Methods: A total of 399 subjects were recruited, of whom 281 were type 2 diabetic patients and 118 normoglycemic subjects.
