The aim of this study was to assess differences in psychological well-being, symptomatic psychological disorders and social participation, between competitive wheelchair basketball participants and those non-participants. Forty-six wheelchair participants, 24 Basketball players (aged 35.60 ± 7.56) and 22 non-players (aged 36.20 ± 6.23), completed three validated self-report questionnaires: Participation Scale (PS), Psychological Well-Being Scale [PWBS] and Symptom Checklist 90 R [SCL-90-R]. ANOVA showed significant overall differences between the two groups. The social restriction score, evaluated by PS, was significantly higher in the non-basketball participants (p = 0.00001) than the basketball participants. The PWB Scale showed significant differences in all 6 dimensions: positive relations with others, environmental mastery, personal growth, purpose in life and self-acceptance (p < 0.01), and autonomy (p < 0.05), with better scores in the basketball participants. The SCL-90-R scores were significantly lower for the basketball group in the following 6 symptomatic dimensions: depression, phobic anxiety, and sleep disorder (p < 0.01), somatization, interpersonal sensitivity and psychoticism (with p < 0.05). It was concluded that competitive wheelchair basketball participants showed better psychological well-being and social skills than those non-participants. 相似文献

Background
Controversy persists regarding the use of protamine sulfate (PS) during carotid endarterectomy (CEA), chiefly because of conflicting experiences reporting both less bleeding and a higher stroke risk. The goal of the present study was to test the hypothesis that reversing heparin with PS after CEA significantly reduces the incidence of bleeding complications without increasing the risk of postoperative stroke.Methods
From January 2010 to December 2012 all consecutive patients undergoing CEA under general anesthesia at our institution received 5,000 U of heparin prior to carotid clamping, which was partially (half-dose) reversed with PS 25 mg immediately after declamping (group I). Heparinization had never been reversed with PS in earlier CEAs performed from 1998 to 2009 at the same institution (group II). All patients were assessed preoperatively and postoperatively by a neurologist, and cerebral magnetic resonance imaging was performed in all group I patients to exclude any silent cerebral infarction. End points of the study were bleeding complications, perioperative (30-day) stroke, and death.Results
Overall, 219 CEAs (201 patients) were performed in group I, and 1,458 CEAs (1,294 patients) in group II. Demographics, risk factors, and preoperative antiplatelet medication were comparable in the two groups. The incidence of adverse events (group I vs group II) was as follows: stroke (0 vs 0.5 % [8/1,458], p = 0.27); death (0 vs 0 %); neck bleeding (0 vs 8.2 % [120/1,458], p < 0.001).Conclusions
The results of the present study demonstrate that (1) partially neutralizing heparin with PS after CEA can significantly reduce the risk of bleeding complications, and (2) there is no association between the administration of PS and the incidence of postoperative stroke. 相似文献47.

Background
Transgender women have 49 times the odds of human immunodeficiency virus (HIV) infection compared to other groups, yet they are disproportionately underserved by current treatment efforts.Purpose
This study aimed to examine culturally unique barriers and facilitators to engagement and retention in HIV care and strengthen efforts to mitigate health disparities, guided by the Models of Gender Affirmation and Health Care Empowerment.Methods
Through 20 interviews and five focus groups (n?=?38), transgender women living with HIV discussed their experiences and life contexts of engagement in and adherence to HIV care and treatment.Results
Our participants faced substantial challenges to adhering to HIV care and treatment, including avoidance of healthcare due to stigma and past negative experiences, prioritization of hormone therapy, and concerns about adverse interactions between antiretroviral treatment for HIV and hormone therapy. Receiving culturally competent, transgender-sensitive healthcare was a powerful facilitator of healthcare empowerment.Conclusions
Recommendations are offered to inform intervention research and guide providers, emphasizing gender affirming HIV care that integrates transition-related healthcare needs. 相似文献49.
