Nursing students' experiences of service-learning at community and hospital pharmacies in Belize: Pedagogical implications for nursing pharmacology.

OBJECTIVES: Many students seem to find pharmacology learning very challenging due to the complexity and variety of drugs they have to study. The number of drugs the students have to learn, the duration of time to learn the medications, and the evolving nature of diseases demanded learning beyond the classroom walls. This study explored and described nursing students' experiences in community and hospital-based pharmacy practice sites during their service-learning and its implications for pharmacology pedagogical practices. METHODS: Kolb's learning theory provided the framework to explore nursing students' 48-hour service-learning experiences at community/hospital-based pharmacies in Belize and its implications for pharmacology pedagogy. The study utilized two qualitative approaches, reflective journals and focus group interviews, to collect data from 46 second-year nursing students. NVivo software and coding schemes were employed to analyze the data from the interviews and reflective journals. RESULTS: Students reported learning medications, integrating classroom pharmacological knowledge at pharmacy practice sites, acquiring and enhancing communication skills, interpreting prescriptions, dispensing medications, drug calculations, taking inventory, doing vital signs, and patient education. In addition, students reported experiencing inter-professional relationships as healthcare team members. Anxiety was a major challenge experienced by many students at the beginning of the service-learning experience. CONCLUSIONS: This study highlights the importance of experiential learning of pharmacology amongst second year nursing students, offering the opportunity to inform and support pharmacotherapeutics educators in designing strategies for more effective teaching of medications to nursing students. It also supports the addition of pharmacy placements to the nursing curriculum' as it shows that nursing students can learn medications, skills, and teamwork from experiential pharmacy site posting. Combining classroom instruction with pharmacy experiential service learning might be an effective complement for teaching nursing pharmacology.

Epidemiology, diagnostics and factors associated with mortality during a cholera epidemic in Nigeria, October 2020-October 2021: a retrospective analysis of national surveillance data.

OBJECTIVES: Nigeria reported an upsurge in cholera cases in October 2020, which then transitioned into a large, disseminated epidemic for most of 2021. This study aimed to describe the epidemiology, diagnostic performance of rapid diagnostic test (RDT) kits and the factors associated with mortality during the epidemic. DESIGN: A retrospective analysis of national surveillance data. SETTING: 33 of 37 states (including the Federal Capital Territory) in Nigeria. PARTICIPANTS: Persons who met cholera case definition (a person of any age with acute watery diarrhoea, with or without vomiting) between October 2020 and October 2021 within the Nigeria Centre for Disease Control surveillance data. OUTCOME MEASURES: Attack rate (AR; per 100 000 persons), case fatality rate (CFR; %) and accuracy of RDT performance compared with culture using area under the receiver operating characteristic curve (AUROC). Additionally, individual factors associated with cholera deaths and hospitalisation were presented as adjusted OR with 95% CIs. RESULTS: Overall, 93 598 cholera cases and 3298 deaths (CFR: 3.5%) were reported across 33 of 37 states in Nigeria within the study period. The proportions of cholera cases were higher in men aged 5-14 years and women aged 25-44 years. The overall AR was 46.5 per 100 000 persons. The North-West region recorded the highest AR with 102 per 100 000. Older age, male gender, residency in the North-Central region and severe dehydration significantly increased the odds of cholera deaths. The cholera RDT had excellent diagnostic accuracy (AUROC=0.91; 95% CI 0.87 to 0.96). CONCLUSIONS: Cholera remains a serious public health threat in Nigeria with a high mortality rate. Thus, we recommend making RDT kits more widely accessible for improved surveillance and prompt case management across the country.

Design and optical characterization of an efficient polarized organic light emitting diode based on refractive index modulation in the emitting layer.

Luminescent liquid Crystal (LC) material is regarded as the most promising material for polarized organic light emission due to their intrinsic characteristics including orderly alignment and luminescence. Nevertheless, the optical extraction efficiency of LC based organic light emitting diodes (OLEDs) devices still requires significant effort and innovation towards real-world applications. In this paper, we propose the design of a highly linearly polarized light-emission from OLEDs with integrated refractive index nanograting in the emissive layer (EML) based on photo aligned luminescent liquid crystal material. The simulation results indicate that the geometrically optimized polarized device yields an external quantum efficiency (EQE) up to 47% with a polarized ratio up to 28 dB at a 550 nm emission wavelength. This conceptual design offers a new opportunity to achieve efficient polarized organic luminescence, and it is (to the best of our knowledge) the first approach that enhances the light extraction of OLEDs based on luminescent liquid crystal via index grating in the EML.
