Objectives: This study aimed to analyze the efficacy of single-dose tranexamic acid (TA) 20 mg/kg preoperatively to reduce blood loss in patients undergoing total knee replacement (TKR).
Methods: A total of 387 patients (82 males, 305 females) undergoing TKR between January 2014 and December 2018 were included in the study. The T + group was administrated intravenous (iv) TA 20 mg/kg 20 min before the skin incision. We determined perioperative blood loss, the amount of drainage postoperative 24 h, the amount of drainage after postoperative 24-48 h, total volume of drains, total volume of blood loss, postoperative hemoglobin and hematocrit levels, and amount of total blood transfusion.
Results: In terms of demographic data, no statistically significant difference was observed between the groups. Perioperative blood loss and total volume of blood loss was found statistically higher in T - group compared to T + group. Postoperatively, the mean hemoglobin and hematocrit levels of T - group were statistically significantly lower than T + group.
Conclusion: A single 20 mg/kg iv TA administration before TKR reduces bleeding during surgery and within 24 h postoperatively.

Abdominal hemorrhage and vascular fragility associated with neurofibromatosis type 1.

We report a case of recurrent abdominal bleeding associated with vascular fragility in a 67-year-old woman with neurofibromatosis type 1 (NF-1). Computed tomography (CT) scan revealed hemorrhagic ascites and a pseudoaneurysm of the sigmoid colon artery, which was suspected to be the source of bleeding. Emergency laparotomy confirmed extremely fragile vessels, requiring repeated surgeries for recurrent bleeding.

We report the case of a 75-year-old woman who presented with fever, right back pain, paresthesia in the right extremities, erythema, purpura, and nodules. She had previously initiated dialysis due to rapidly progressive glomerulonephritis and was transferred to our hospital. Imaging studies revealed multiple cerebral and splenic infarcts and hemorrhage encapsulating the right kidney, likely due to microaneurysms in multiple renal arteries.

Background And Purpose: Lobar intracerebral hemorrhage (ICH) is associated with a high risk of recurrence, particularly in elderly patients, where cerebral amyloid angiopathy (CAA) is often the primary cause. Diagnostic markers of CAA-related ICH, including subarachnoid hemorrhage (SAH) and finger-like projection (FLP), have recently been developed. Here, we aimed to explore the associations between SAH, FLP and the risk of ICH recurrence in lobar ICH patients.

Aims/hypothesis: UK standard care for type 2 diabetes is structured diabetes education, with no effects on HbA, small, short-term effects on weight and low uptake. We evaluated whether remotely delivered tailored diabetes education combined with commercial behavioural weight management is cost-effective compared with current standard care in helping people with type 2 diabetes to lower their blood glucose, lose weight, achieve remission and improve cardiovascular risk factors.
Methods: We conducted a pragmatic, randomised, parallel two-group trial.
