Vascular access: Femoral, radial and large-bore alternative access.

Vascular access for coronary, peripheral, and structural interventions has changed significantly over the past two decades. The evolving demand for both large-bore access for valvular interventions and mechanical support devices, and for safer access for coronary interventions, in patients with comorbidities have driven progress in these areas. This review will provide an overview of the techniques of arterial access in the femoral, forearm (radial and ulnar), and alternative (transcarotid, transaxillary, and transcaval) locations based on the latest evidence and experience.

Effectiveness of conversion surgery in stage IV gastric cancer.

Background: For patients with stage IV gastric cancer (GC), systemic therapy is often the standard treatment, but the prognosis remains poor. Conversion surgery (CS) has emerged as a potential therapeutic option for selected patients who had certain response to chemotherapy. This study aims to compare the survival outcomes of CS versus continued chemotherapy (CT) in stage IV GC.

Arrhythmogenic atrial remodeling during pregnancy in mice.

Background: Pregnancy is associated with greater vulnerability to supraventricular tachyarrhythmias.

Objective: As the underlying mechanisms remain to be elucidated, we investigated whether pregnancy induces atrial remodeling that might contribute to this.

Methods: Atrial electrophysiological and contractile properties were examined in nonpregnant and pregnant (P) mice.

Effects of Organic Substrate Amendments on Selected Organic Fractions and Biochemical Parameters under Different Soils.

The application of organic substrates can affect soil respiration, dehydrogenase (DH-ase) activity, dissolved organic carbon (DOC), and humic acid (HA) fractions. This study aimed to evaluate the effects of five organic substrates in the organic fractions of degraded alluvial soil, acid sulfate soil, and sandy soils and the physicochemical properties of the soil. Soil samples were amended at a rate of 5 tons ha with (1) water hyacinth compost, (2) sugarcane filter cake compost, (3) biogas sludge-rice straw compost, (4) vermicompost, and (5) sludge.
