Little is known about how beliefs about heredity as a cause of health conditions might influence preventive and interpersonal behaviors among those individuals with low genetic and health literacy. We explored causal beliefs about podoconiosis, a neglected tropical disease (NTD) endemic in Ethiopia. Podoconiosis clusters in families but can be prevented if individuals at genetically high risk wear shoes consistently. Adults (N = 242) from four rural Ethiopian communities participated in qualitative assessments of beliefs about the causes of podoconiosis. Heredity was commonly mentioned, with heredity being perceived as (1) the sole cause of podoconiosis, (2) not a causal factor, or (3) one of multiple causes. These beliefs influenced the perceived controllability of podoconiosis and in turn, whether individuals endorsed preventive and interpersonal stigmatizing behaviors. Culturally informed education programs that increase the perceived controllability of stigmatized hereditary health conditions like podoconiosis have promise for increasing preventive behaviors and reducing interpersonal stigma. 相似文献

Smart textiles have attracted huge attention due to their potential applications for ease of life. Recently, smart textiles have been produced by means of incorporation of electronic components onto/into conductive metallic yarns. The development, characterizations, and electro-mechanical testing of surface mounted electronic device (SMD) integrated E-yarns is still limited. There is a vulnerability to short circuits as non-filament conductive yarns have protruding fibers. It is important to determine the best construction method and study the factors that influence the textile properties of the base yarn. This paper investigated the effects of different external factors, namely, strain, solder pad size, temperature, abrasion, and washing on the electrical resistance of SMD integrated silver-coated Vectran (SCV) yarn. For this, a Vectran E-yarn was fabricated by integrating the SMD resistor into a SCV yarn by applying a vapor phase reflow soldering method. The results showed that the conductive gauge length, strain, overlap solder pad size, temperature, abrasion, and washing had a significant effect on the electrical resistance property of the SCV E-yarn. In addition, based on the experiment, the E-yarn made from SCV conductive thread and 68 Ω SMD resistor had the maximum electrical resistance and power of 72.16 Ω and 0.29 W per 0.31 m length. Therefore, the structure of this E-yarn is also expected to bring great benefits to manufacturing wearable conductive tracks and sensors. 相似文献

Chlamydia trachomatis is one of the most common causes of sexually transmitted diseases in sexually active males and females. Infertility is one of the serious complications of urogenital chlamydial infections. This study was carried out in Chuwahit town and the surrounding village, which is located southwest of Gondar town. The main objective was to estimate the prevalence of urogenital Chlamydia trachomatis among males aged fifteen years and above. The design used was a cross sectional survey. First catch urine was collected from males 15 years and above and interviews were made using a questionnaire. The urine samples were tested with an Enzyme Immuno-Assay (EIA), which is useful in rapid detection of chlamydia antigen. Among 199 males included in the study, thirty-three (16.6%) had laboratory evidence of urogenital Chlamydia trachomatis. The mean (SD) age of the study subjects was 29.3 (+/- 9) years. Students (8 out of 21, 38%) had the highest prevalence of urogenital Chlamydia compared to the other groups (OR = 4.10, 95% CI = 1.12, 14.48). The magnitude of urogenital chlamydia infection in males was high in the study area. Health professionals need to consider genital Chlamydial infections in the management and control of sexually transmitted diseases. Increasing the awareness of students towards urogenital Chlamydial trachomatis and teaching them about the benefits of using condoms is recommended. 相似文献

ABSTRACT: Background: Current practice guidelines recommend active management of the third stage of labor. We compared practices of three maternity care provider disciplines in management of third‐stage labor and the justifications for their approach. Methods: This study is a cross‐sectional survey of maternity practitioners in usual practice settings in British Columbia. All 199 obstetricians, all 82 midwives, and a random sample of family physicians practicing intrapartum maternity care (one‐third, or 346) were surveyed The three main outcome measures by discipline were the method preferred in managing third‐stage labor, the reasons given for the chosen method, and views on the appropriateness of the current third‐stage labor guideline. Results: The overall response rate was 57.8 percent. Response rates indicating that the participants were “aware of guideline” were the following: obstetricians, 85.3 percent; family physicians, 53.7 percent; and midwives, 97.8 percent. Response rates indicating that the participants “agreed with guideline” were the following: obstetricians, 95.2 percent; family physicians, 97.6 percent; and midwives, 51.2 percent. Response rates indicating that “oxytocin should be given with anterior shoulder” were the following: obstetricians, 71.1 percent; family physicians, 68.3 percent; and midwives, 26.7 percent. Response rates indicating that “routine active management of third stage of labor should be the norm” were the following: obstetricians, 79.2 percent; family physicians, 60.2 percent; and midwives, 17 percent. All results were statistically significant (p < 0.01). Conclusions: A major difference was found between physicians and midwives in the management of third‐stage labor. Physicians routinely implemented active management of the third stage of labor; midwives preferred expectant approaches, principally based on women’s preference. Provincial data did not show differences in postpartum hemorrhage or transfusion rates by practitioner type. (BIRTH 35:3 September 2008) 相似文献

The rapid pace of genomic discovery has raised public expectation and concerns about the utility of new discoveries and their potential to exacerbate health disparities. Improving literacy concerning gene and environmental (GxE) contributors to disease is needed to avoid commonly observed deterministic misconceptions about genomics. Mental models approaches that incorporate community engagement processes could be used to inform GxE literacy-building interventions. We used a mental models approach to describe and systematically compare expert and lay understanding of GxE interactions, using the example of podoconiosis, a non-infectious lymphedema endemic in highland Ethiopia. Methods included: (1) specifying elicitation questions for a literature review, (2) eliciting an expert model, (3) eliciting a lay model, and (4) comparing the two models. We used a coding scheme to identify lay participants’ knowledge gaps, misunderstandings, and extra knowledge relative to the expert standard. Results indicated that lay participants’ viewed poverty as an important susceptibility factor and considered heredity and contagion to have a joint causal influence. Experts did not endorse either of these viewpoints. Conventional expert-based interventions aimed to correct misconceptions about behaviors important for prevention may be stymied by lay views that social environmental factors have more important influences on health outcomes. GxE literacy interventions that consider multiple levels of influence including social determinants of health and personal resilience to augment health education strategies are needed in diverse settings. Novel communication approaches will be needed to help target audiences disentangle long-held conceptions of heredity and contagion. 相似文献

OBJECTIVE: to determine the prevalence and type of intestinal parasites in HIV infected and uninfected patients with diarrhea. DESIGN: A cross-sectional study was conducted at Gondar University hospital, Northwest Ethiopia, between March 2003 and October 2004. PATIENTS AND METHODS: A total 312 consecutive diarrheic patients were included in the study. Stool specimens were collected and examined for intestinal parasites following direct, formol-ether concentration and modified acid fast staining methods. RESULTS: Among the patients, 63.8% were found to be HIV seropositive. The prevalence of intestinal parasites in HIV seropositive and seronegative diarrheic patients was 30.6% and 33.6%, respectively. The most prevalent parasites were Strongyoides stercoralis (9.0%) and Entamoeba histolytica (8.3%) followed by Ascaris lumbricoides (5.4%) and Cryptosporidium species (5. 1%). CONCLUSION AND RECOMMENDATION: The prevalence of intestinal parasites in diarrheic patients was very high. Institution of appropriate intervention measures are needed to reduce morbidity in such patients. 相似文献
