This paper reports on participants’ views regarding factors contributing to the vulnerability of teenagers with intellectual disability to sexual abuse. The study took place at two special schools located in a village of KwaZulu-Natal. Data were gathered using by individual interviews, which were conducted in a face-to-face manner with life orientation teachers (8), school nurses (2), a clinical psychologist at the local hospital, and social workers (2). The interviews were also conducted with two parents, a traditional healer and spiritual diviner. Data was thematically analysed. The vulnerability factors were grouped into three broad categories, namely: individual, family and community factors. The existence of a number of vulnerability factors suggests that efforts to mitigate the problem should occur at various levels, with which an individual is interacting.  相似文献

ABSTRACT: BACKGROUND: Important unanswered questions remain on the impact of international sporting events on the sex industry. Speculation about increased demand and supply of sex work often generates significant attention, but also additional funding for HIV programmes. This study assessed whether changes occurred in the demand and supply of paid sex during the 2010 Soccer World Cup in South Africa. METHODS: Trained sex worker interviewers conducted face-to-face semi-structured interviews among consenting female sex workers during May-September 2010. Using bivariate analyses we compared supply, demand, sexual risk-taking, and police and health services contact pre-World Cup, to levels during the World Cup and after the event. RESULTS: No increases were detected in indicators of sex work supply, including the proportion of sex workers newly arrived in the city (< 2.5% in each phase) or those recently entering the trade (<= 1.5%). Similarly, demand for sex work, indicated by median number of clients (around 12 per week) and amount charged per transaction ($13) remained similar in the three study periods. Only a third of participants reported observing any change in the sex industry ascribed to the World Cup. Self-reported condom-use with clients remained high across all samples (> 92.4% in all phases). Health-care utilisation decreased non-significantly from the pre- to during World Cup period (62.4% to 57.0%; P = 0.075). Across all periods, about thirty percent of participants had interacted with police in the preceding month, two thirds of whom had negative interactions. CONCLUSIONS: Contrary to public opinion, no major increases were detected in the demand or supply of paid sex during the World Cup. Although the study design employed was unable to select population-based samples, these findings do not support the public concern and media speculation prior to the event, but rather signal a missed opportunity for public health action. Given the media attention on sex work, future sporting events offer strategic opportunities to implement services for sex workers and their clients, especially as health service utilisation might decrease in this period.  相似文献

目的探讨掌上超声在野战环境下建立髂动脉枪弹伤大出血动物模型的应用价值。 方法在野战环境下,选择长白猪8只,实验前采集血压、心率等指标。采用掌上超声定位右侧髂动脉,并标记体表弹着点,由专业射手进行射击并保持自由出血30 s,通过连续监测生命体征变化确定是否出现失血性休克。在实验后处死动物,沿弹道进行解剖,明确髂动脉断裂情况。 结果8只动物均一次性建模成功。与建模前相比,建模后收缩压降低[(144.38±14.74)mmHg vs (110.00±29.89)mmHg,P=0.001,1 mmHg=0.133 kPa],舒张压降低[(96.63±17.20)mmHg vs (74.63±22.06)mmHg,P<0.001],平均动脉压降低[(110.63±15.99)mmHg vs (88.38±27.12)mmHg,P=0.003],心率增快[(67.25±7.73)次/分 vs (94.50±16.62)次/分,P=0.004],符合失血性休克表现。枪弹射击后,即刻见鲜红色血液喷射而出。解剖后大体观察7只(87.5%)动物髂动脉完全破裂,1只(12.5%)髂动脉不完全断裂,所有动物肌肉损伤严重,股骨均可见粉碎性骨折。 结论在野战环境下,掌上超声引导髂动脉枪弹伤建模成功率高,动物模型稳定,为进一步探索枪弹伤致交界部位致命性大出血的研究奠定了基础。  相似文献

Purpose:

The current study investigated the pain profiles of patients with subacute non-specific low back pain attending an outpatient return-to-work rehabilitation programme. Differences in symptoms of distress (depression and anxiety) and return to work between the pain-profile groups were assessed.

Methods:

Sixty-five volunteers who met the eligibility criteria and had complete follow-up data were included in the analysis. The mean age was 38.8 years (minimum 18, maximum 64); 38 (58.5%) were men. The median time since onset of low back pain was 30 days. Cluster analysis was used to categorize patients into groups according to pain severity scores (VAS).

Results:

Two distinct clusters—severe pain and moderate pain—emerged. There were significant differences in depressive and anxiety symptoms between the pain profiles. Further, return-to-work rates varied significantly between the two groups (31% in the severe pain cluster compared to 90% in the moderate pain cluster).

Conclusion:

Although both groups showed significant improvements in depression and anxiety symptoms over time, the severe pain cluster scored higher at discharge (higher scores indicating worse outcomes). These results highlight the importance of early identification of sub-groups at risk so that rehabilitation interventions can be focused with the goal of minimizing long-term disability.  相似文献

Mechanistic study of biological processes via Quantum Dots (QDs) remain constrained by inefficient QD delivery methods and consequent altered cell function. Here the authors present a rapid method to label activated receptor populations in live cancer cells derived from medulloblastoma and glioma tumors. The authors used QDs to bind the extracellular domain of Epidermal Growth Factor Receptor (EGF-R) proteins and then induced receptor activation to facilitate specific detection of intracellular, activated EGF-R subpopulations. Such labeling enables rapid identification of biological markers characteristic of tumor type, grade and chemotherapy resistance. FROM THE CLINICAL EDITOR: In this paper, a rapid, quantum dot-based method is presented with the goal of labeling activated receptor populations in live cancer cells. More accurate characterization of medulloblastoma and glioma cancer cells using this biomarker detection technique may lead to a more specific targeted therapy.  相似文献
