The aim of the study was to investigate whether or not there is a significant relationship between varicocele and SFJ insufficiency. This study included 200 men with (study group) and 200 men without (control group) primary varicocele which was initially diagnosed by observation during the Valsalva manoeuver. Subsequently, scrotal and lower extremity venous Doppler ultrasonography (USG) was performed by a senior radiologist, and participants with testicular veins >3.0 mm in diameter and reverse blood flow were determined to have varicocele. SFJ insufficiency was defined as retrograde flow in the SFJ of longer than 0.5 s. Retrograde venous flow in the pampiniform plexus was determined 3.5% (study) versus 0.0% (control) and 77.0% (study) versus 0.0% (control) in the right testis and left testis, respectively, and bilaterally at 11.5% (study) versus 0.0% (control). The presence of SFJ insufficiency was also found to be higher in the study group than in the control group (unilaterally: 26.0% versus 15.0%; bilaterally: 14.0% versus 5.0%). The current study demonstrates a statistically significant relationship between varicocele and SFJ insufficiency and supports the argument that varicocele is not a local disease and may be attributable to a systemic vascular insufficiency. Additional studies with larger series are needed to further elucidate this topic.

Importance: In the Atrial Cardiopathy and Antithrombotic Drugs in Prevention After Cryptogenic Stroke (ARCADIA) randomized clinical trial, anticoagulation did not prevent recurrent stroke among patients with a recent cryptogenic stroke and atrial cardiopathy. It is unknown whether anticoagulation prevents covert infarcts in this population.

Objective: To test the use of apixaban vs aspirin for prevention of nonlacunar covert infarcts after cryptogenic stroke in patients with atrial cardiopathy.

Background: To assess the safety and efficacy of flush endovenous laser ablation (fEVLA) in the treatment of chronic venous insufficiency (CVI).

Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines, a systematic review aiming to identify studies published from inception to March 2024 was conducted. The investigation covered single-arm studies and studies comparing fEVLA to standard EVLA (sEVLA).

Blood flow from the saphenofemoral junction(SFJ) tributaries may cause recurrence of varicose veins. Flush occlusion is defined as the total occlusion of the great saphenous vein(GSV) right to the saphenofemoral junction. The purpose of this study was to evaluate the efficacy and safety of flush endovenous thermal ablation with saphenofemoral junction tributary occlusion.

Burden of Cardio-Cerebrovascular and Renal Diseases Attributable to Systolic Hypertension in France in 2021.

Hypertension

February 2025

Direction des maladies non transmissibles, Santé publique France, Saint-Maurice, France (C.G., A.G., M.J.T., V.O.).

Background: Hypertension is the most common chronic disease and a major modifiable risk factor for cardio-cerebrovascular and renal diseases. This study estimated the national burden of hypertension, defined as systolic blood pressure ≥140 mm Hg, on morbidity and mortality in 2021 in France.

Methods: For all diseases causally associated with hypertension (cardiovascular diseases, chronic kidney diseases, and dementia), the number and proportion of cases attributable to hypertension in adults aged ≥35 years were estimated using population attributable fractions.

Efficacy and safety of SGLT2 inhibitors with and without glucagon-like peptide 1 receptor agonists: a SMART-C collaborative meta-analysis of randomised controlled trials.

Lancet Diabetes Endocrinol

Article Synopsis
  • SGLT2 inhibitors and GLP-1 receptor agonists both have positive effects on cardiovascular and kidney health in patients with type 2 diabetes, leading to a study comparing their benefits when used together or separately.
  • A meta-analysis from various trials showed that SGLT2 inhibitors effectively reduced risks of major cardiovascular events and kidney disease progression for patients whether or not they were taking GLP-1 receptor agonists.
  • The consistency of these benefits across different outcomes indicates that SGLT2 inhibitors can be beneficial for all diabetic patients, regardless of GLP-1 receptor agonist usage.
