A Risk Analysis and Safety Context on Nigeria Road

The starting point of this work was analysing of data from road safety corp.  Applying safety to tanker/trailer on Nigeria road.  Road transport system was studied.  Accident was examined using Haddon Matrix. The three basic factors of road crash human, vehicle and road environment was pin point. However, a ban of trucks on Nigeria road was scrutinized with time lag effect on other industries. Tankers / Trailers expected casualty was estimated using probabilities. The summary table of Tankers / Trailers Road Traffic Crashes between  2007- 2010 by RSC was used in the work. Recommendation and conclusion Keywords: Safety on road, Expected Casualty, Accident, Risk on road, Hazard theor

Perceived social support as a protective factor against psychological distress in the context of COVID-19-related stress and sexual minority status in Nigeria.

Sexual minority individuals report higher COVID-19-related stress that may mediate higher psychological distress. However, this relationship and the role of social support have not been investigated in low/middle-income settings like Nigeria. Our study tested independent associations of psychological distress with sexual orientation, COVID-19-related stress, and perceived social support and whether perceived social support moderated these relationships. In an online survey, 966 Nigerians (21.7% sexual minority, n = 210) were assessed for sexual orientation, COVID-19-related stress, and perceived social support, and psychological distress. Sexual minority status was associated with higher COVD-19-related stress (r = .13, 95% CI [0.06, 0.19]), perceived social support (r = .07, [0.01, 0.13]), and psychological distress (r = .09, [0.02, 0.17]). Furthermore, we demonstrated two moderation effects: psychological distress was highest among sexual minority participants with low perceived social support and lowest among heterosexual participants with high perceived social support (β = 0.09, [0.02, 0.16]). Among sexual minorities, the association between COVID-19-related stress and psychological distress was strongest and weakest among those with low and high perceived social support, respectively, but this effect was absent among heterosexual participants (β = −0.14, [−0.21, −0.06]). Our finding suggests social support as a protective mechanism against adverse health outcomes among heterosexual and sexual minority individuals in Nigeria

Adaptation of the Wound Healing Questionnaire universal-reporter outcome measure for use in global surgery trials (TALON-1 study): mixed-methods study and Rasch analysis

BackgroundThe Bluebelle Wound Healing Questionnaire (WHQ) is a universal-reporter outcome measure developed in the UK for remote detection of surgical-site infection after abdominal surgery. This study aimed to explore cross-cultural equivalence, acceptability, and content validity of the WHQ for use across low- and middle-income countries, and to make recommendations for its adaptation.MethodsThis was a mixed-methods study within a trial (SWAT) embedded in an international randomized trial, conducted according to best practice guidelines, and co-produced with community and patient partners (TALON-1). Structured interviews and focus groups were used to gather data regarding cross-cultural, cross-contextual equivalence of the individual items and scale, and conduct a translatability assessment. Translation was completed into five languages in accordance with Mapi recommendations. Next, data from a prospective cohort (SWAT) were interpreted using Rasch analysis to explore scaling and measurement properties of the WHQ. Finally, qualitative and quantitative data were triangulated using a modified, exploratory, instrumental design model.ResultsIn the qualitative phase, 10 structured interviews and six focus groups took place with a total of 47 investigators across six countries. Themes related to comprehension, response mapping, retrieval, and judgement were identified with rich cross-cultural insights. In the quantitative phase, an exploratory Rasch model was fitted to data from 537 patients (369 excluding extremes). Owing to the number of extreme (floor) values, the overall level of power was low. The single WHQ scale satisfied tests of unidimensionality, indicating validity of the ordinal total WHQ score. There was significant overall model misfit of five items (5, 9, 14, 15, 16) and local dependency in 11 item pairs. The person separation index was estimated as 0.48 suggesting weak discrimination between classes, whereas Cronbach's α was high at 0.86. Triangulation of qualitative data with the Rasch analysis supported recommendations for cross-cultural adaptation of the WHQ items 1 (redness), 3 (clear fluid), 7 (deep wound opening), 10 (pain), 11 (fever), 15 (antibiotics), 16 (debridement), 18 (drainage), and 19 (reoperation). Changes to three item response categories (1, not at all; 2, a little; 3, a lot) were adopted for symptom items 1 to 10, and two categories (0, no; 1, yes) for item 11 (fever).ConclusionThis study made recommendations for cross-cultural adaptation of the WHQ for use in global surgical research and practice, using co-produced mixed-methods data from three continents. Translations are now available for implementation into remote wound assessment pathways
