Wonder-women: case studies of pregnant university students - change and transition.

Changes have occurred within educational settings over the past 30 years, creating a more equal learning environment for women. Despite the fact that women aged 18-39 years now outnumber men within New Zealand universities, there is still evidence of inequality for pregnant university students.A qualitative case-study approach was used to explore and describe the stages and patterns of transition from being a university student to becoming a pregnant university student. Each woman demonstrated the complexity of the transitions. The pregnant body and becoming visible were factors that impacted on all five women who participated in this study. The case studies describe how pregnancy intervened in the experience of being a student.Various coping mechanisms were employed by these pregnant university students. The research suggests that they find balance through compartmentalizing aspects of their lives. They attribute educational and personal outcomes to luck. These strategies have enabled these women to aim for educational or personal success. Yet it remains clear that the university does not provide adequate support for these pregnant university students. Policies and resources need to be established to aid pregnant university students in this process of transition

Bioabsorption and Effectiveness of Long-Lasting Permethrin-Treated Uniforms Over Three Months Among North Carolina Outdoor Workers

Abstract Background Vector-borne diseases are an important cause of morbidity and mortality in the USA. Effective, convenient prevention methods are needed. Long-lasting permethrin-impregnated (LLPI) clothing can prevent tick bites, however, additional information is needed on the real-world effectiveness and safety of this preventative measure. Methods In this pilot study, we recruited state and county park employees from North Carolina to wear LLPI uniforms for three months during the summer of 2016. We collected spot urine samples for biomonitoring of permethrin metabolites at one week, one month and three months after first use of the LLPI uniform. Following three months of wear, we collected pants and socks and analyzed them for permethrin content and mortality to ticks and mosquitoes. Results Thirteen park employees were included in the analysis. Bioactive amounts of permethrin remained in all clothing swatches tested, although there was great variability. Tick mortality was high, with 78% of pant and 88% of sock swatches having mean knockdown percentages ≥ 85%. In contrast, mosquito mortality was low. Over the study period, the absorbed dosage of permethrin averaged < 4 μg/kg/d of body weight based on measurements of three metabolites. Conclusions LLPI clothing retained permethrin and bioactivity against ticks after three months of use in real-world conditions. The estimated absorbed dosage of permethrin was well below the U.S. EPA level of concern, suggesting that LLPI clothing can be used safely by outdoor workers for tick bite prevention

App-based versus standard six-minute walk test in pulmonary hypertension: mixed methods study

Background: Pulmonary arterial hypertension (PAH) is a chronic disease of the pulmonary vasculature that can lead to heart failure and premature death. Assessment of patients with PAH includes performing a 6-minute walk test (6MWT) in clinics. We developed a smartphone app to compute the walked distance (6MWD) indoors, by counting U-turns, and outdoors, by using satellite positioning. Objective: The goal of the research was to assess (1) accuracy of the indoor 6MWTs in clinical settings, (2) validity and test-retest reliability of outdoor 6MWTs in the community, (3) compliance, usability, and acceptance of the app, and (4) feasibility of pulse oximetry during 6MWTs. Methods: We tested the app on 30 PAH patients over 6 months. Patients were asked to perform 3 conventional 6MWTs in clinic while using the app in the indoor mode and one or more app-based 6MWTs in outdoor mode in the community per month. Results: Bland-Altman analysis of 70 pairs of conventional versus app-based indoor 6MWDs suggests that the app is sometimes inaccurate (14.6 m mean difference, lower and upper limit of agreement: –133.35 m to 162.55 m). The comparison of 69 pairs of conventional 6MWDs and community-based outdoor 6MWDs within 7 days shows that community tests are strongly related to those performed in clinic (correlation 0.89), but the interpretation of the distance should consider that differences above the clinically significant threshold are not uncommon. Analysis of 89 pairs of outdoor tests performed by the same patient within 7 days shows that community-based tests are repeatable (intraclass correlation 0.91, standard error of measurement 36.97 m, mean coefficient of variation 12.45%). Questionnaires and semistructured interviews indicate that the app is usable and well accepted, but motivation to use it could be affected if the data are not used for clinical decision, which may explain low compliance in 52% of our cohort. Analysis of pulse oximetry data indicates that conventional pulse oximeters are unreliable if used during a walk. Conclusions: App-based outdoor 6MWTs in community settings are valid, repeatable, and well accepted by patients. More studies would be needed to assess the benefits of using the app in clinical practice. Trial Registration: ClinicalTrials.gov NCT04633538; https://clinicaltrials.gov/ct2/show/NCT0463353

The mobile-based 6-minute walk test: usability study and algorithm development and validation

Background: The 6-min walk test (6MWT) is a convenient method for assessing functional capacity in patients with cardiopulmonary conditions. It is usually performed in the context of a hospital clinic and thus requires the involvement of hospital staff and facilities, with their associated costs. Objective: This study aimed to develop a mobile phone–based system that allows patients to perform the 6MWT in the community. Methods: We developed 2 algorithms to compute the distance walked during a 6MWT using sensors embedded in a mobile phone. One algorithm makes use of the global positioning system to track the location of the phone when outdoors and hence computes the distance travelled. The other algorithm is meant to be used indoors and exploits the inertial sensors built into the phone to detect U-turns when patients walk back and forth along a corridor of fixed length. We included these algorithms in a mobile phone app, integrated with wireless pulse oximeters and a back-end server. We performed Bland-Altman analysis of the difference between the distances estimated by the phone and by a reference trundle wheel on 49 indoor tests and 30 outdoor tests, with 11 different mobile phones (both Apple iOS and Google Android operating systems). We also assessed usability aspects related to the app in a discussion group with patients and clinicians using a technology acceptance model to guide discussion. Results: The mean difference between the mobile phone-estimated distances and the reference values was −2.013 m (SD 7.84 m) for the indoor algorithm and −0.80 m (SD 18.56 m) for the outdoor algorithm. The absolute maximum difference was, in both cases, below the clinically significant threshold. A total of 2 pulmonary hypertension patients, 1 cardiologist, 2 physiologists, and 1 nurse took part in the discussion group, where issues arising from the use of the 6MWT in hospital were identified. The app was demonstrated to be usable, and the 2 patients were keen to use it in the long term. Conclusions: The system described in this paper allows patients to perform the 6MWT at a place of their convenience. In addition, the use of pulse oximetry allows more information to be generated about the patient’s health status and, possibly, be more relevant to the real-life impact of their condition. Preliminary assessment has shown that the developed 6MWT app is highly accurate and well accepted by its users. Further tests are needed to assess its clinical value.</p

A systematic review of cardiac rehabilitation registries

Introduction: Despite cardiac rehabilitation (CR) being recommended in clinical practice guidelines internationally these services are under-utilised, programs are not standardised and quality improvement methods and outcomes are rarely published. National registries are an important strategy to characterise service delivery, quality and outcomes, yet the number, type and components of national CR registries has not been reported. Aims: To identify and describe national and international CR registries internationally, and summarise their key features. Methods: The literature reporting on CR registries used to monitor the quality of CR at a national and international-level was systematically reviewed. A search of four databases was conducted in July 2016, with two reviewers independently screening title/abstracts and full-texts for inclusion. Data were extracted from included studies, independently checked by a second reviewer and synthesised qualitatively. Results: Eleven articles were included in the review comprising seven national registries and one international registry (of 12 European countries) for a total sample of 265,608 patients. Data were most commonly provided to the registry via a web-based application, and included individual-level data (i.e., sociodemographic characteristics, medical history, and clinical measurements). When reported, service-level data most commonly included wait times, program enrolment and completion. The overarching governance, funding modes (e.g., industry (n=2), government (n=1)), and incentives for registry participation (e.g., benchmarking, financial reimbursement, or mandatory requirement) varied widely. Conclusion: The use of national and international registries for characterising CR and providing a benchmark for quality improvement is in its early stages but shows promise for national and global benchmarking.
