This aim of this study was to assess the clinical utility of quantitative ST-segment depression (STD) for refining the risk stratification of non-ST elevation acute coronary syndromes in the prospective, multinational Global Registry of Acute Coronary Events (GRACE). Quantitative measurements of STD on admission electrocardiograms were evaluated independently by a core laboratory, and their predictive value for in-hospital and cumulative 6-month mortality was examined. Although more severe STD is a marker of increased short- and long-term mortality, it is also associated with higher risk clinical features and biomarkers. Thus, after adjustment for these clinically important predictors, quantitative STD does not provide incremental prognostic value beyond simple dichotomous evaluation for the presence of STD. Furthermore, adopting quantitative instead of the prognostically proven qualitative evaluation of STD does not improve risk discrimination afforded by the validated GRACE risk models. In conclusion, the findings do not support the quantification of STD in routine clinical practice beyond simple evaluation for the presence of STD as an integral part of comprehensive risk stratification using the GRACE risk score. 相似文献

BACKGROUNDFunctional bowel disorder (FBD) may be caused by a decrease in disaccharidase activity. Thus, the timely diagnosis of disaccharidase deficiency could lead to a better prognosis in patients with this condition.AIMTo determine the potential value of intestinal disaccharidases glucoamylase, maltase, sucrase, and lactase in understanding the etiology and pathogenesis of FBD.METHODSA total of 82 FBD patients were examined. According to the Rome IV criteria (2016), 23 patients had diarrhea-predominant irritable bowel syndrome (IBS), 33 had functional diarrhea, 10 had constipation-predominant IBS, 4 had functional constipation, and 12 had mixed IBS. The Dahlqvist method was used to measure disaccharidase activity in the brush-border membrane of mature enterocytes of the small intestine, in duodenal biopsies obtained during esophagogastroduodenoscopy.RESULTSLactase deficiency was detected in 86.5% of patients, maltase deficiency in 48.7%, sucrase deficiency in 50%, and glucoamylase deficiency in 84.1%. The activities of all enzymes were reduced in 31.7% of patients, and carbohydrase deficiency was detected in 63.5% of patients. The low activity of enzymes involved in membrane digestion in the small intestine was found in 95.2% of patients.CONCLUSIONIn 78 of the 82 patients with FBD, gastrointestinal symptoms were associated with disaccharidase deficiency. 相似文献

Hair and urine concentrations of the nonsteroidal selective androgen receptor modulator GSK2881078 were examined following single oral administration to investigate its hair incorporation and estimate the general suitability of hair testing for selected androgen receptor modulators. Hair segments were collected following a single dose of 1.5 mg GSK2881078 by repeated shaving of scalp hair at Week 0 (blank), Week 1 (representing the pre-application period), Week 3 (ideally focusing the time of incorporation), and Weeks 5 and 9 (post-administration period). The intact compound and various (at least 4) hydroxy-metabolites exhibited similar elimination profiles. The peak urinary concentration (approximately 920 pg/ml) was observed after 8 h and is reduced to the detection limit (2 pg/ml) on Day 42 following administration of 760 μg GSK2881078. Correspondingly, hair concentrations of GSK2881078 (intact compound only) following a single oral dose of 1.5 mg GSK2881078 reached a peak concentration of 1.7 pg/mg in the segments collected 3 weeks post administration, representing the time of ingestion. The concentration rapidly declined to trace amounts of 0.7 (Week 5) and 0.2 pg/mg (Week 9), respectively. In conclusion, measurement of the intact compound GSK2881078 is feasible for both urine and hair analysis. However, concentrations in hair after single oral administration are in the low pg/mg range and can only be detected, if the segments cover the administration period. 相似文献
