Background: Platelet count and function are particularly damaged by cardiopulmonary bypass (CPB). This study evaluated the effects of a novel CPB circuit in terms of platelet count and activation, and postoperative need for blood products.

Methods: One hundred patients undergoing coronary grafting were randomized in two groups: control group (n = 50) and test group (n = 50, surface modifying additives circuit, SMA group). Blood samples were taken before, during, and after CPB. Postoperative blood loss, number of transfused blood products, and postoperative variables were recorded.

Results: The platelet count decreased less in the SMA group compared to the control group (end of CPB: respectively, 165 +/- 9 x 10(3)/mm3 vs 137 +/- 8 x 10(3)/mm3; p < 0.01). This was paralleled by a reduction in beta-thromboglobulin plasma levels in the SMA group. There was a trend to decreased blood loss in the SMA group, but the difference was significant only in patients taking aspirin preoperatively (p < 0.05). In the SMA group nearly 50% less fresh frozen plasma and platelet units were administered (p < 0.01). No operative deaths were observed.

Conclusions: The use of circuits with surface additives is clinically safe, preserves platelet levels, and attenuates platelet activation. This may lead to a reduced need for blood products.

The presence of an aberrant right hepatic artery (a-RHA) could influence the oncological and postoperative outcomes after pancreaticoduodenectomy (PD). A comparative study was conducted, including patients who underwent PD with a-RHA or with normal RHA anatomy. The primary endpoints were R1 resection in all margins (pancreatic, anterior, posterior, superior mesenteric artery, and portal groove), overall survival (OS), and disease-free survival (DFS).

Objective: Shared medical appointments (SMAs) are an innovative care delivery method that provides delivery of clinical care while also supporting self-management. Their usefulness for mental health conditions has only briefly been explored, though early evidence demonstrates their utility for supporting mental health management. Therefore, this study set out to better understand the views that adults with anxiety and depression have towards SMAs as a way of receiving care to support self-management in primary care.

Background: Neuromuscular disorders (NMDs) constitute a heterogeneous group of disorders that affect motor neurons, neuromuscular junctions, and muscle fibers, resulting in symptoms such as muscle weakness, fatigue, and reduced mobility. These conditions significantly affect patients' quality of life and impose a substantial burden on caregivers. Spinal muscular atrophy (SMA) is a relatively common NMD in children that presents in various types with varying degrees of severity.

Objective: Bladder tissue models have been developed using smooth muscle cells (SMCs) on various scaffolds to mimic bladder morphology and physiology. This study investigates the effects of co-culturing fetal and adult SMCs on growth properties and protein profiles to understand cellular interactions and population kinetics.

Methods: Bladder tissue samples from 10 adult and 10 fetal New Zealand rabbits were divided into 5 groups: adult SMCs (A), fetal SMCs (F), 50%A+50%F (A+F), 75%A+25%F (3A+F), and 25%A+75%F (A+3F).

Backgrounds: Renal interstitial fibrosis (RIF) constitutes the ultimate pathological alteration in nearly all chronic kidney diseases (CKD). Mesenchymal stem cell conditioned medium (MSC-CM) exhibits an alleviating impact on renal fibrosis; however, the underlying mechanism remains unclear. The objective of this study was to explore whether MSC-CM regulates the expression of α-smooth muscle actin (α-SMA), Transforming growth factor-β1 (TGF-β1), Hypoxia-inducible factor-1α (HIF-1α), Nuclear receptor coactivators (NCOA1), and SRY-related high mobility (Sox9).
