Psychological sense of community is defined as feelings of belongingness and a shared belief that community members will meet one another's needs. Psychological sense of community has four dimensions: membership, influence, needs fulfillment, and emotional connection. In this study, multigroup confirmatory factor analysis was used to examine the first and second-order factor structure of the brief sense of community scale (BSCS) between male and female Hispanic/Latinx adolescents from an urban community (N = 947). To help validate the BSCS model, the second-order factor model was tested with regression to predict the measures of intrapersonal psychological empowerment and ethnic identity, as constructs conceptually related to psychological sense of community. Findings support that: (1) psychological sense of community can be measured through the BSCS and as a four-factor model among Hispanic/Latinx youth, supporting McMillan and Chavis's (1986) original theoretical discussions; (2) while no differences between genders were present at the model-level, there was path-specific variation; and (3) intrapersonal psychological empowerment and ethnic identity were associated with psychological sense of community. 相似文献

BackgroundSeasonal influenza imposes a significant health and economic burden in South Africa, particularly in populations vulnerable to severe consequences of influenza. This study assesses the cost-effectiveness of South Africa’s seasonal influenza vaccination strategy, which involves vaccinating vulnerable populations with trivalent inactivated influenza vaccine (TIV) during routine facility visits. Vulnerable populations included in our analysis are persons aged ≥ 65 years; pregnant women; persons living with HIV/AIDS (PLWHA), persons of any age with underlying medical conditions (UMC) and children aged 6–59 months.MethodWe employed the World Health Organisation’s (WHO) Cost Effectiveness Tool for Seasonal Influenza Vaccination (CETSIV), a decision tree model, to evaluate the 2018 seasonal influenza vaccination campaign from a public healthcare provider and societal perspective. CETSIV was populated with existing country-specific demographic, epidemiologic and coverage data to estimate incremental cost-effectiveness ratios (ICERs) by comparing costs and benefits of the influenza vaccination programme to no vaccination.ResultsThe highest number of clinical events (influenza cases, outpatient visits, hospitalisation and deaths) were averted in PLWHA and persons with other UMCs. Using a cost-effectiveness threshold of US$ 3 400 per quality-adjusted life year (QALY), our findings suggest that the vaccination programme is cost-effective for all vulnerable populations except for children aged 6–59 months. ICERs ranged from ~US$ 1 750 /QALY in PLWHA to ~US$ 7 500/QALY in children. In probabilistic sensitivity analyses, the vaccination programme was cost-effective in pregnant women, PLWHA, persons with UMCs and persons aged ≥65 years in >80% of simulations. These findings were robust to changes in many model inputs but were most sensitive to uncertainty in estimates of influenza-associated illness burden.ConclusionSouth Africa's seasonal influenza vaccination strategy of opportunistically targeting vulnerable populations during routine visits is cost-effective. A budget impact analysis will be useful for supporting future expansions of the programme. 相似文献

BACKGROUND: Since first reported in 1996, endoscopic minimally invasive surgery of the cervical region has been shown to be safe and effective in the treatment of benign thyroid and parathyroid disease. The endoscopic transaxillary technique uses a remote lateral approach to the thyroid gland. Because of the perceived difficulty in accessing the contralateral anatomy of the thyroid gland, this technique has typically been reserved for patients with unilateral disease. OBJECTIVES: The present study examines the safety and feasibility of the transaxillary technique in dissecting and assessment of both thyroid lobes in performing near total thyroidectomy. METHODS: Prior to this study we successfully performed endoscopic transaxillary thyroid lobectomy in 32 patients between August 2003 and August 2005. Technical feasibility in performing total thyroidectomy using this approach was accomplished first utilizing a porcine model followed by three human cadaver models prior to proceeding to human surgery. After IRB approval three female patients with histories of enlarging multinodular goiter were selected to undergo endoscopic near total thyroidectomy. RESULTS: The average operative time for all models was 142 minutes (range 57-327 min). The three patients in this study had clinically enlarging multinodular goiters with an average size of 4 cm. The contralateral recurrent laryngeal nerve and parathyroid glands were identified in all cases. There was no post-operative bleeding, hoarseness or subcutaneous emphysema. CONCLUSION: Endoscopic transaxillary near total thyroidectomy is feasible and can be performed safely in human patients with bilateral thyroid disease. 相似文献

Purpose. The study reports the initial biological evaluation of targeted polymeric glycol chitosan vesicles as carrier systems for doxorubicin (Dox).
Methods. Transferrin (Tf) was covalently bound to the Dox-loaded palmitoylated glycol chitosan (GCP) vesicles using dimethylsuber- imidate (DMSI). For comparison, glucose targeted niosomes were prepared using N-palmitoyl glucosamine. Biological properties were studied using confocal microscopy, flow cytometry, and cytotoxicity assays as well as a mouse xenograft model.
Results. Tf vesicles were taken up rapidly with a plateau after 1-2 h and Dox reached the nucleus after 60-90 min. Uptake was not increased with the use of glucose ligands, but higher uptake and increased cytotoxicity were observed for Tf targeted as compared to GCP Dox alone. In the drug-resistant A2780AD cells and in A431 cells, the relative increase in activity was significantly higher for the Tf-GCP vesicles than would have been expected from the uptake studies. All vesicle formulations had a superior in vivo safety profile compared to the free drug.
Conclusions. The in vitro advantage of targeted Tf vesicles did not translate into a therapeutic advantage in vivo. All vesicles reduced tumor size on day 2 but were overall less active than the free drug. 相似文献

This commentary conceptualizes recovery mutual aid organizations and other grassroots, nonprofessional recovery support institutions as indigenous cultures, identifies ethical issues that can arise in professional and scientific collaboration with such cultures, and provides a checklist that can guide professional and scientific collaborations with grassroots recovery support organizations. 相似文献

Background:Rational emotive education (REE) program aims to improve the behavioral and mental health of students. This study objective was to evaluate the effect of an REE program on stress among undergraduate students of religious education program in Nigerian Universities.Method:One hundred and fifty (150) religious education undergraduates who had high level of stress participated in the study. Participants were assigned to 2 different groups. The treatment group had 75 participants and while control group also had 75 participants. Data collection was done using the Perceived Stress Scale (PSS-10) while data analysis was done using independent sample t test and paired t test statistics at .05 probability level.Results:The REE program resulted in a significant decrease in level of stress among undergraduate students of religious education program in the treatment group compared with those students in the control group. Also, the effect of the REE program was maintained during the follow-up among undergraduate students of religious education program exposed to it.Conclusion:The REE program can be used to assist undergraduate students of religious education program to manage their stress. 相似文献
