Recent clinical and experimental evidence has challenged the traditional concept of the venous system as a "passive" element in the genesis and evolution of intracranial vascular malformations. The authors review the clinical and experimental evidence linking the venous system and its anomalies to the genesis of various intracranial vascular malformations, including dural arteriovenous fistulas, cavernous malformations, parenchymal arteriovenous malformations, and capillary telangiectasia. They also describe the potential significance of different associations of these vascular anomalies.

Objectives: This study aimed to investigate the microbiological and clinical heterogeneity of community-onset bloodstream infections (BSIs) and identify features to support targeted empirical antibiotic therapy in the Emergency Department (ED).

Methods: Clinical and microbiological data from 992 BSI cases (1,135 isolates) diagnosed within 24 hours of ED admission at IRCCS Humanitas Research Hospital, Milan, Italy (January 2015-June 2022), were analyzed. Drug resistance was interpreted using EUCAST-2023.

The pan-PPAR agonist lanifibranor reduces portal pressure independent of fibrosis reduction through the splanchnic vasculature.

Portal hypertension (PH) can cause severe complications in patients with advanced chronic liver disease (aCLD). The pan-peroxisome proliferator-activated receptor (pan-PPAR) agonist lanifibranor reduces portal pressure in preclinical models of aCLD. Since the effect on PH might be secondary to fibrosis improvement, we investigated the effect of lanifibranor on PH, hepatic and splanchnic angiogenesis in mouse models of fibrotic and prehepatic non-fibrotic PH.

Venous thromboembolism (VTE), consisting of both deep vein thrombosis (DVT) and pulmonary embolism (PE), is an extremely common condition both in the United States and worldwide. Not only is the diagnosis associated with significant morbidity and mortality for patients, but also it imposes a deleterious financial burden on the US healthcare system. Diagnosis may be challenging due to variability in clinical presentation and requires a sequential workup including assessment of clinical pretest probability for VTE, D-dimer testing, and imaging.

Expansion of home hemodialysis (HHD) provides an opportunity to improve clinical outcomes, reduce cost of care, and address the staffing challenges currently faced in caring for patients with kidney failure on replacement therapy. To increase HHD expansion, current practices and barriers to home dialysis must be examined and addressed. One such barrier is vascular access for HHD; although tunneled hemodialysis central venous catheters (CVCs) have been used for decades, physicians still hesitate to send patients home without a mature, functional arteriovenous access.
