In autosomal dominant polycystic kidney disease (ADPKD), aberrant activation of the mammalian target rapamycin (mTOR) pathway is associated with progressive enlargement. The drug sirolimus suppresses mTOR signaling.In this 18-month, open-label, randomized, controlled trial, we sought to determine whether halts growth in volume among patients ADPKD. We randomly assigned 100 between ages 18 and 40 years receive either (target dose, 2 mg daily) or standard care. All had an estimated creatinine...

Chronic obstructive pulmonary disease (COPD) is associated with increased cardiovascular mortality. Endothelial dysfunction may underpin this association. This cross-sectional study aimed to determine the impact of airflow obstruction, systemic inflammation, oxidative stress, sympathetic activation, hypoxaemia and physical activity on endothelial function in COPD. In stable COPD patients, assessments by flow-mediated dilatation (FMD), risk (Pocock score), obstruction (forced expiratory...

Abstract Background General practitioners often care for patients with several concurrent chronic medical conditions (multimorbidity). Recent data suggest that multimorbidity might be observed more than isolated diseases in primary care. We explored the age- and gender-related prevalence of compared these estimates to other common specific found Swiss Methods analyzed from FIRE (Family Medicine ICPC Research using Electronic Medical Record) project database, representing a total 509,656...

Patients with severe thrombocytopenia are at risk for bleeding during insertion of central venous catheters (CVCs). Although most guidelines recommend preprocedural platelet (PLT) transfusions a threshold less than 50 × 10(9) /L, there is only weak evidence supporting such recommendations.The current study aimed to establish safe PLT transfusion trigger in patients CVC placements. We performed retrospective single-center analysis 604 insertions 193 acute leukemia receiving intensive...

Traditionally, single-unit red blood cell transfusions were believed to be insufficient treat anemia, but recent data suggest that they may lead a safe reduction of transfusion requirements. We tested this hypothesis by changing from double- policy.We performed retrospective cohort study in patients with hematologic malignancies receiving intensive chemotherapy or hematopoietic stem transplantation.

Tackling antibiotic resistance represents one of the major challenges in modern medicine, and limiting antibiotics' overuse first step this fight. Most antibiotics are prescribed primary care settings, lower respiratory tract infections (LRTIs) most common indications for their prescription. An expert panel conducted an extensive report on C-reactive protein point-of-care (CRP POC) testing evaluation LRTIs its usefulness to limit prescriptions. The stated that CRP POC is a potentially useful...
