Multicenter Study Comparative Study Observational Study
Management of ST-segment elevation myocardial infarction in predominantly rural central China: A retrospective observational study.
The degree of adherence to current guidelines for clinical management of ST-segment elevation myocardial infarction (STEMI) is known in developed countries and large Chinese cities, but in predominantly rural areas information is lacking. We assessed the application of early reperfusion therapy for STEMI in secondary and tertiary hospitals in Henan province in central China. Data were retrospectively collected from 5 secondary and 4 tertiary hospitals in Henan concerning STEMI patients treated from January 2011 to January 2012, including management strategy, delay time, and inhospital mortality. ⋯ Inhospital mortality was 5.8%, and similar between secondary and tertiary hospitals (6.0% vs 5.6%; P = 0.183). Two-thirds of STEMI patients did not receive early reperfusion, and tertiary hospitals mostly failed to take advantage of around-the-clock primary percutaneous coronary intervention. Actions such as referrals are warranted to shorten prehospital delay, and the concerns of patients and doctors regarding reperfusion risk should be addressed.

The type of postoperative cognitive decline after surgery under spinal anesthesia is unknown. We investigated the type of postoperative cognitive decline after total knee arthroplasty (TKA). Neuropsychological testing was conducted and the changes in cerebrospinal fluid (CSF) biomarkers after surgery were evaluated. ⋯ Our results suggest that frontal-executive function declined 1 week after TKA under spinal anesthesia. The CSF biomarker analysis indicated that TKA under regional anesthesia might not cause neuronal damage.

Blood Stasis syndrome (BSS) is one of the major syndromes in Traditional East Asia medicine (TEAM). Modern research of BSS began in the late1980s. ⋯ BSS-related studies have increased in quantity and quality, but there are limitations to them which require improvement in research productivity and academic influence.

Vitamin K antagonists (VKAs) are highly effective but have a narrow therapeutic index and require routine monitoring of the INR. The primary aim of pharmacogenetics (PGx) is to optimize patient care, achieving drug treatments that are personalized according to the genetic profile of each patient. The best-characterized genes involved in VKA PGx involve pharmacokinetics (VKORC1) and pharmacodynamics (CYP2C9) of VKA metabolism. ⋯ We performed a retrospective, matched case-control study to determine associations between multiple gene variants, drug intake, and any major adverse effects in anticoagulated patients, monitored in 2 Italian anticoagulation clinics. Our results show that anticoagulated patients have a high risk of adverse events if they are carriers of 1 or more genetic polymorphisms in the VKORC1 (rs9923231) and CYP2C9 (rs1799853 and rs1057910) genes. Information on CYP2C9 and VKORC1 variants may be useful to identify individualized oral anticoagulant treatment for each patient, improve management and quality of VKA anticoagulation control, and monitor drug surveillance in pharmacovigilance programs.

We examined injuries of the dentato-rubro-thalamic tract (DRTT), cortico-ponto-cerebellar tract (CPCT), dorsal spinocerebellar tract (SCT), and inferior cerebellar peduncle (ICP) in a patient with severe ataxia following bilateral tegmental pontine hemorrhage (PH), using diffusion tensor tractography (DTT). ⋯ Using DTT, concurrent injuries of the DRTT, CPCT, dorsal SCT, and ICP were demonstrated in a patient with severe ataxia following PH. Our result suggests the necessity of evaluation of these neural tracts in patients who develop ataxia after brain injury.
