Exploring the use and quality of Internet discussion forums in pregnancy : a qualitative analysis
The Internet is widely used as a source of health information to assist decision making in pregnancy. Concerningly, the quality of information shared on online pregnancy forums is unclear. Our objectives were to explore online pregnancy forum health-related use and evaluate quality of information shared. This retrospective qualitative study had two phases of data collection and analysis. First, thematic analysis of a representative sample (n = 480) of posts explored motivators for forum use. Second, a subgroup (n = 153) of threads with clinical content was assessed for congruence with reputable sources. Common motivators for forum engagement were a desire for lived experience, unlimited access, and the opportunity to express emotions. Of 1098 responses sharing advice, information, or experience, 601 (54.7%) were accurate; 230 (20.9%) were erroneous, incomplete, or misleading; and 267 (24.3%) lacked credible evidence. Of these, 60 (5.5%) were potentially harmful. Responses often directed women to a health care practitioner, but concerningly, failed to refer ten women in need of urgent medical assessment. Few discussions were self-regulating, with only 12 of 230 (5.2%) poor-quality messages subsequently rectified. Exchange of information and emotional support among peers are key functions of online pregnancy forums. There is a modest prevalence of poor-quality or potentially harmful information but more concerningly a lack of peer moderation. We suggest health care practitioners ensure pregnant women have a clear understanding of when clinical consultation is required. Clinicians may wish to discuss the supportive community aspects of online forums in cases where offline support is lacking. [Abstract copyright: © 2019 Wiley Periodicals, Inc.
Exposing the myths of household water insecurity in the global north: A critical review
Safe and secure water is a cornerstone of modern life in the global North. This article critically examines a set of prevalent myths about household water in high-income countries, with a focus on Canada and the United States. Taking a relational approach, we argue that household water insecurity is a product of institutionalized structures and power, manifests unevenly through space and time, and is reproduced in places we tend to assume are the most water-secure in the world. We first briefly introduce âmodern waterâ and the modern infrastructural ideal, a highly influential set of ideas that have shaped household water provision and infrastructure development over the past two centuries. Against this backdrop, we consolidate evidence to disrupt a set of narratives about water in high-income countries: the notion that water access is universal, clean, affordable, trustworthy, and uniformly or equitably governed. We identify five thematic areas of future research to delineate an agenda for advancing scholarship and actionâincluding challenges of legal and regulatory regimes, the housing-water nexus, water affordability, and water quality and contamination. Data gaps underpin the experiences of household water insecurity. Taken together, our review of water security for households in high-income countries provides a conceptual map to direct critical research in this area for the coming years

Validation of the Bluebelle Wound Healing questionnaire (WHQ) for assessment of surgical site infection in primary surgical wounds after hospital discharge
Background
Accurate assessment of surgicalâsite infection (SSI) is crucial for surveillance and research. Selfâreporting patient measures are needed because current SSI tools are limited for assessing patients after leaving hospital. The Bluebelle Wound Healing Questionnaire (WHQ) was developed for patient or observer completion; this study tested its acceptability, scale structure, reliability and validity in patients with closed primary wounds after abdominal surgery.
Methods
Patients completed the WHQ (selfâassessment) within 30 days after leaving hospital and returned it by post. Healthcare professionals completed the WHQ (observer assessment) by telephone or faceâtoâface. Questionnaire response rates and patient acceptability were assessed. Factor analysis and Cronbach's α examined scale structure and internal consistency. Testâretest and selfâ versus observer reliability assessments were performed. Sensitivity and specificity for SSI discrimination against a faceâtoâface reference diagnosis (using Centers for Disease Control and Prevention criteria) were examined.
Results
Some 561 of 792 selfâassessments (70·8 per cent) and 597 of 791 observer assessments (75·5 per cent) were completed, with few missing data or problems reported. Data supported a singleâscale structure with strong internal consistency (α greater than 0·8). Reliability between testâretest and selfâ versus observer assessments was good (Îș 0·6 or above for the majority of items). Sensitivity and specificity for SSI discrimination was high (area under the receiver operating characteristic (ROC) curve 0·91).
Conclusion
The Bluebelle WHQ is acceptable, reliable and valid with a singleâscale structure for postdischarge patient or observer assessment of SSI in closed primary wounds
Postnatal depression in Southern Brazil: prevalence and its demographic and socioeconomic determinants
<p>Abstract</p> <p>Background</p> <p>Studies investigating the prevalence of postnatal depression (PND) show rates ranging from 5% to 36.7%. The investigation of age, race, educational levels, religion and income as risk factors for PND has yielded conflicting results. The aim of this study is to investigate the prevalence of PND in women residing in Southern Brazil and the associated risk factors.</p> <p>Methods</p> <p>This is population-based cross-sectional study of women residing in Porto Alegre who delivered in June 2001. A sample of 271 participants were selected from the Record of Living Newborn Infants of the State Health Department (the official Brazilian database and stores the name and address of all women who give birth to living newborn infants) using a process based on pseudo-random numbers which choose a random sample from 2.000 records. Once the addresses were identified, the women were visited at their place of residence (home, hotel, boarding house and prison), with the interviews taking place between the 6<sup>th </sup>and the 8<sup>th </sup>week after delivery.</p> <p>The association between the risk factors and PND was investigated through bivariate analysis using Pearson's chi-square test. Student's t-test was used to analyze the continuous variables. To identify independent risk factors, multivariate analysis was performed using hierarchical levels with a predefined model that took into account the time relationship between PND and the risk factors. Cox's regression was used to calculate the prevalence ratios.</p> <p>Results</p> <p>The PND prevalence rate found was 20.7% (CI 95% 15.7 â 25.7). After adjusting for confounding variables, per capita income was found to have a significant association with PND.</p> <p>Conclusion</p> <p>The prevalence of PND is higher than the figures found in most developed countries and similar to the figures found in developing countries. Differences in PND by regions or countries can be partially explained by the effect of income on the mediation of risk factors. In low income populations, women should be routinely evaluated for postnatal depression, and those with no partner or spouse are likely to require further care from health services and should be given the benefit of mental health prevention programs.</p
Low Doses of Ionizing Radiation Promote Tumor Growth and Metastasis by Enhancing Angiogenesis
Radiotherapy is a widely used treatment option in cancer. However, recent evidence suggests that doses of ionizing radiation (IR) delivered inside the tumor target volume, during fractionated radiotherapy, can promote tumor invasion and metastasis. Furthermore, the tissues that surround the tumor area are also exposed to low doses of IR that are lower than those delivered inside the tumor mass, because external radiotherapy is delivered to the tumor through multiple radiation beams, in order to prevent damage of organs at risk. The biological effects of these low doses of IR on the healthy tissue surrounding the tumor area, and in particular on the vasculature remain largely to be determined. We found that doses of IR lower or equal to 0.8 Gy enhance endothelial cell migration without impinging on cell proliferation or survival. Moreover, we show that low-dose IR induces a rapid phosphorylation of several endothelial cell proteins, including the Vascular Endothelial Growth Factor (VEGF) Receptor-2 and induces VEGF production in hypoxia mimicking conditions. By activating the VEGF Receptor-2, low-dose IR enhances endothelial cell migration and prevents endothelial cell death promoted by an anti-angiogenic drug, bevacizumab. In addition, we observed that low-dose IR accelerates embryonic angiogenic sprouting during zebrafish development and promotes adult angiogenesis during zebrafish fin regeneration and in the murine Matrigel assay. Using murine experimental models of leukemia and orthotopic breast cancer, we show that low-dose IR promotes tumor growth and metastasis and that these effects were prevented by the administration of a VEGF receptor-tyrosine kinase inhibitor immediately before IR exposure. These findings demonstrate a new mechanism to the understanding of the potential pro-metastatic effect of IR and may provide a new rationale basis to the improvement of current radiotherapy protocols
