Determinants of obesity and perception of weight in hypertensive patients in rural South Africa

Objective: The objective of the study was to identify factors associated with being overweight or obese, and perceptions of weight by hypertensive patients living in rural South Africa.Design: This was a nested cross-sectional study.Setting: The setting was primary healthcare clinics close to Manguzi Hospital, KwaZulu-Natal.Subjects: Subjects were 109 males and 391 females, prescribed at least one antihypertensive medication aged ≥ 18 years.Outcome measures: The primary outcome measure was body mass index (BMI) ≥ 25 kg/m2. The secondary outcome measure was recognition of being overweight by those with a BMI ≥ 25 kg/m2.Results: The mean age was 58 years. Three hundred and ninety-one (78%) participants were female, and the majority had never been to school or had attended primary school only. Three hundred and eleven (62%) participants were overweight or obese, with a BMI ≥ 25 kg/m2. Factors associated with being overweight or obese included having high cholesterol [adjusted odds ratio (OR) 10.62, 95% confidence interval (CI): 1.22-92.4, p-value 0.032], and having never smoked (adjusted OR 3.22, 95% CI: 1.38-7.52, p-value 0.007. Human immunodeficiency virus (HIV) was associated with a lower risk of being overweight or obese (adjusted OR 0.52 for BMI ≥ 25, 95% CI: 0.31-0.89, p-value < 0.0001). Only 12% of participants who were overweight or obese perceived that they were overweight. Participants with a BMI ≥ 25 kg/m2 were most likely to recognise they were overweight if they had high cholesterol, diabetes or HIV.Conclusion: Almost two thirds of participants were overweight or obese, and of these, only 12% perceived that they were overweight. Educating patients about obesity, particularly when they have other cardiovascular risk factors such as hypertension, is of public health importance.Keywords: obesity, overweight, weight perception, hypertension, body mass inde

Serogroups of Dichelobacter nodosus, the cause of footrot in sheep, are randomly distributed across England

We present the largest and most representative study of the serological diversity of Dichelobacter nodosus in England. D. nodosus causes footrot and is one of the top five globally important diseases of sheep. The commercial vaccine, containing nine serogroups, has low efficacy compared with bivalent vaccines. Our aim was to investigate the prevalence and distribution of serogroups of D. nodosus in England to elucidate whether a bivalent vaccine could protect the national flock. Farmers from 164 flocks submitted eight interdigital swabs from eight, preferably diseased, sheep. All serogroups, A–I, were detected by PCR in 687/1150 D. nodosus positive swabs, with a prevalence of 2.6–69.3% of positive swabs per serogroup. There was a median of two serogroups per flock (range 0–6). Serogroups were randomly distributed between, but clustered within, flocks, with 50 combinations of serogroups across flocks. H and B were the most prevalent serogroups, present in > 60% of flocks separately but in only 27% flocks together. Consequently, a bivalent vaccine targeting these two serogroups would protect 27% of flocks fully (if only H and B present) and partially, if more serogroups were present in the flock. We conclude that one bivalent vaccine would not protect the national flock against footrot and, with 50 combinations of serogroups in flocks, flock-specific vaccines are necessary

Analytical attractions and the techno-continuum: Conceptualising data obsessions and consequences in elite sport

The proliferation of sports science and technological innovation within performance settings has precipitated the generation of increasing volumes of data to aid athletes. Copious data production has also perpetuated the privileging of scientific information, and a ‘thirst’ for ‘more data’ as an unproblematic ‘truth’. Of significance is not merely the use of technology for the production of data-for-data’s sake, or the utility of data for a greater cause (e.g., the good of the team), but the quest for personalised data for individual athletes to be analysed, and reflected upon ad nauseam. Furthering scholarship on disciplining bodies, we argue that increased technological consumption, and the related excessive quantification of athletes’ bodies via data production, adds further insecurity into performance sports work. Finally, attention is given to the cultural step-change new techno-dispositions may now present

Taking simulation out of its "safe container"-exploring the bidirectional impacts of psychological safety and simulation in an emergency department

ABSTRACT: BACKGROUND: Simulation facilitators strive to ensure the psychological safety of participants during simulation events; however, we have limited understanding of how antecedent levels of psychological safety impact the simulation experience or how the simulation experience impacts real-world psychological safety. METHODS: We explored the experience of participants in an embedded, interprofessional simulation program at a large tertiary emergency department (ED) in Australia. We engaged in theoretical thematic analysis of sequential narrative surveys and semi-structured interviews using a previously derived framework of enablers of psychological safety in healthcare. We sought to understand (1) how real-world psychological safety impacts the simulation experience and (2) how the simulation experience influences real-world psychological safety. RESULTS: We received 74 narrative responses and conducted 19 interviews. Simulation experience was both influenced by and impacted psychological safety experienced at the individual, team, and organizational levels of ED practice. Most strikingly, simulation seemed to be an incubator of team familiarity with direct impact on real-world practice. We present a model of the bidirectional impact of psychological safety and simulation within healthcare environments. CONCLUSION: Our model represents both opportunity and risk for facilitators and organizations engaging in simulation. It should inform objectives, design, delivery, debriefing, and faculty development and firmly support the situation of simulation programs within the broader cultural ethos and goals of the departments and organizations.
