We evaluated nucleic acid amplification testing (NAAT) for Zika virus on whole-blood specimens compared with NAAT on serum and urine specimens among asymptomatic pregnant women during the 2015–2016 Puerto Rico Zika outbreak. Using NAAT, more infections were detected in serum and urine than in whole blood specimens.  相似文献

The aim of this study was to identify the epidemiology, aetiology as well as the knowledge, attitudes, and practices relating to burn injuries in Palestine. A mixed‐method approach was used. A survey was distributed to a total of 1500 households selected by randomised approach. The survey was standardised based on World Health Organisation''s guidelines for conducting community surveys on injury. Additionally, there were 12 focus group discussions and 10 key informant interviews to collect rich qualitative data. In the West Bank and Gaza, 1.5% of Palestinians had experienced serious burn injuries in the 12 months. The total sample of 1500 yields a margin of error (plus/minus) = 2.5% at a 95% level of confidence and a response distribution (P = 50%) with 3% non‐response rate. Of the 1500 households approached, 184 reported a total of 196 burn injuries, with 87.2% occurring inside the home: 69.4% were females and 39.3% were children. The main source of reported cause of burn was heat and flame (36%), electric current (31.6%), hot liquid (28.6%), and chemicals (2.7%). The most common first aid for burns was pouring water (74.7%). People in rural, refugee, and Bedouin settings had the highest incidence of burns. This study provides the burn prevalence rate, explanatory factors that contribute to the frequency of burns in Palestine. Making burn prevention a higher priority within the national policy is crucial.  相似文献

Abstract

The purpose of this study was to test the hypothesis that positional distraction provides immediate relief of unilateral leg pain suspected to be caused by lumbar-nerve root irritation. Thirty subjects with true neurological signs were randomly assigned to a treatment group or control group. The treatment group received positional distraction for five minutes and the control group lay in side-lying for the same amount of time. Pain intensity, pain location, and SLR test height data was taken pre- and post-test. Statistical analysis was completed with the Wilcoxin-signed rank test for the data of pain intensity and with the paired sample t-test for the SLR height. The treatment group was found to have significantly less pain, more centralization of pain, and an increase in SLR test height (p-values of 0.001, 0.006, and 0.005 respectively). The control group showed no significant change (p-values of 0.506, 0.480, 0.884).  相似文献

Community-based interventions (CBI) have been targeted as a potential means of tackling cardiovascular disease in women. However, there have been mixed results in terms of their impact on health, with at least some of this being attributed to high attrition rates. This study explores factors that may be contributing to the low retention of women in cardiovascular CBIs. In 2009, Sister to Sister, a national organization that sponsors community health fairs, provided free cardiovascular health screenings for a total of 9,443 women nationwide. All participants were invited to enroll in a 1 year, survey-based observational study to assess the effectiveness of these community health screenings. Of these 9,443 women, 5.9 % actively participated in the follow-up study. Participants were more likely to have health insurance (75.5 vs. 65.3 %, p < 0.001), have an annual income above 75,000 dollars (26.7 vs. 19.7 %, p < 0.001), and identify themselves as white (50.0 vs. 31.5 %, p < 0.001). They were also more likely to have hypertension (32.1 vs. 27.4 %, p = 0.018) and metabolic syndrome (35.7 vs. 20.4 %, p < 0.001). Our results suggest that white, affluent women with health insurance and cardiovascular risk factors are more likely to engage in CBIs that require longitudinal assessment. This study gives insight into the demographics, socioeconomic status, and cardiovascular comorbidities of women who participate in cardiovascular CBIs. The results may prove to be useful in understanding the biopsychosocial barriers to participation in CBIs in order to develop more effective interventions in the future.  相似文献
