The occurrence of performance anxiety among musicians 总被引:1,自引:0,他引:1
A questionnaire was given to the students and faculty of the University of Iowa School of Music to learn about their experiences with and attitudes about performance anxiety. Forty-nine (16.5%) of the 302 respondents indicated that their musical performance was impaired by anxiety. Over 21% of the respondents indicated that they experienced marked distress while performing and 16.1% indicated that performance anxiety had adversely affected their careers. Women more frequently reported distress and impairment due to performance anxiety than men. Age was not found to affect problems with performance anxiety. Poor concentration, rapid heart rate, tremor, sweating, and dry mouth were the most commonly reported anxious symptoms. Drug and alcohol use among this group of musicians was minimal. The findings suggest that performance anxiety is an important problem that may in some instances warrant medical treatment. 相似文献

A patient is presented who developed diffuse T-wave inversion during a course of ECT. Review of the literature suggests that prolonged T-wave inversion associated with ECT is an uncommon and probably benign finding not warranting an interruption of a course of electrotherapy. 相似文献

Summary The potencies of several muscarine receptor antagonists in blocking either the autoinhibition of acetylcholine release or the muscarinic contraction of the sphincter muscle upon acetylcholine release were investigated in the guinea-pig iris. The agonist at pre- or postjunctional muscarine receptors was acetylcholine released upon field stimulation (5.5 Hz, 2 min) of the irides preloaded with 14C-choline. The stimulation-evoked 14C-overflow was doubled in the presence of atropine 0.1 mol/l but unaffected by the agonist (±)-methacholine (50 mol/l). Thus, under the present stimulation conditions, the autoinhibition of acetylcholine release on the guinea-pig iris cholinergic nerves was nearly maximally activated. Isotonic contractions of the irides upon field stimulation consisted of a rapid, atropine (0.1 mol/l). peak phase followed by a sustained contraction which involved a cholinergic and a non-cholinergic stimulation of the sphincter muscle. The M2-selective antagonists methoctramine (10 mol/l) and gallamine (100 µmol/l). increased both the 14Goverflow and the peak contractions evoked by field stimulation. In contrast, the M3-selective antagonist hexahydrosiladifenidol (0.1–10 mol/l) failed to affect the evoked 14C-release but concentration-dependently (1–10 mol/l) reduced the iris contractions. Pirenzepine (10 mol/l) enhanced the evoked 14C-overflow and inhibited the peak contractions (0.1–10 mol/l; maximal effect at 10 mol/l). The low potency of the antagonist at both receptor sites indicates that an M1 muscarine receptor is not involved. The results are consistent with the idea of M2 muscarine receptors mediating autoinhibition of acetylcholine release in the guinea-pig iris and M3-like receptors inducing the contraction of the sphincter muscle.

The Xpert GBS real-time PCR assay for the detection of group B streptococci (GBS) in antepartum screening samples was evaluated on amniotic fluid samples collected from 139 women with premature rupture of membrane at term. When any intrapartum positive result from the Xpert GBS or culture was considered a true positive, the sensitivities of the Xpert GBS and culture were 92.3% and 84.6%, respectively. This assay could enhance exact identification of candidates for intrapartum antibiotic prophylaxis. 相似文献

This single-center retrospective study reported the outcome of 19 children treated with a reduced-intensity conditioning (RIC) regimen prior to allogeneic stem cell transplantation (allo-SCT), for hematologic malignancies (n = 17), bone marrow failure (n = 1), and neuroblastoma (n = 1). Children were ineligible for standard myeloablative conditioning because of severe comorbidities (n = 9), a previous auto or allo-SCT (n = 7) or a prior history of extensive chemotherapy (n = 3). All patients underwent a fludarabine-based RIC regimen, and received grafts from matched-related donors (n = 5), match-unrelated donors (n = 6), or unrelated cord blood (UCB, n = 8). In this series, two patients treated with UCB failed to engraft and 63% achieved full donor chimerism at day 100 after allo-SCT. With a median follow-up of 537 d (range, 115-4136), treatment-related mortality was 16% and overall survival was 47%. The principal cause of death was disease relapse (n = 7). Acute graft versus host disease (GVHD) occurred in 53% of patients, while only 10% developed extensive chronic GVHD. Overall, results from this series suggest that RIC allo-SCT can be a valid alternative treatment option in unfit children with malignant hematological diseases. Prospective studies are needed to enlarge pediatric experience in this domain and better identify those children more suitable for a RIC allo-SCT approach. 相似文献
