Nursing students’ perceptions of support and active learning regarding simulation-based education in Lesotho: A quantitative study

Background. Simulation has taken centre stage in health sciences education in the context of the increasing adoption of a competency-based curriculum. Simulation replicates facets of the real world in an interactive manner that allows students to learn clinical skills and develop clinical reasoning skills in a safe learning environment. Facilitators have a responsibility to provide adequate instructional and psychological support to the students, while facilitating active and self-directed learning in the simulation environment. Objective. To explore and describe students’ perceptions of support and active learning regarding simulation-based education (SBE) in Lesotho. Methods. A quantitative descriptive exploratory study was conducted using a validated questionnaire. A total of 275 nursing students participated in the study. A stratified systematic random sampling method was used and data were analysed using SPSS version 27. Results. The majority of participants (87.9%) had a positive perception of support that was offered prior, during and after simulation, which they appreciated. Active learning was also perceived positively, as most of the participants indicated that they actively participated in, and not merely observed, simulation. The results showed significant associations between an opportunity given to students to discuss simulation objectives with the teacher and various institutions (p<0.05 (p=0.01)). Institutions with trained simulation facilitators provided students the opportunity to discuss simulation objectives with their teacher. Conclusion. The study showed that student support and active learning are essential when conducting SBE. Supporting students and actively involving them in the learning process lead to effective learning

Common lower extremity injuries in female high school soccer players in Johannesburg east district

Objectives. Soccer is one of the sports in South Africa which hasseen an increase in the participation of youth and adult female players. The aim of this study was to determine point and 1-year prevalence, profile of injuries that affect female soccer players, associations between injuries and player position, age, use of equipment, frequency of play, and training duration. Methods. A retrospective questionnaire-based descriptive survey of 103 first team high school female soccer players in the Johannesburg east district was conducted.Results. The 1-year prevalence for the participants who reportedinjuries was 46% (N=47) and the point prevalence was 33% (N=34). From these, a total of 78 and 42 injuries for the 1-year and point prevalence respectively were reported. An extended duration of skills (p=0.0001) and fitness (p=0.02) training in this population reduced the likelihood of incurring an injury. The older the participants, the more chance there was of sustaining injuries (p=0.01). The participants who wore shin guards were less prone to shin/leg injuries (p=0.01), the relative odds being 0.35. Themidfielders had more foot and toe injuries than the other players(p=0.05). Starting age (p=0.78), frequency of play (p=0.83), wearing of shoes (p=0.54) and stretching had no influence on injury. The knee and ankle were the main locations of injury, with defenders and midfielders mostly being injured. Conclusion. A decrease in the duration of training for both skills and fitness and not wearing shin guards are risk factors for injury in female soccer players in high school. The profile of injuries andthe risk factors determined from this study do not differ from the studies done in male adolescent and adult soccer players

Sarcocystis cafferi n. sp. (Protozoa : Apicomplexa) from the African Buffalo (Syncerus caffer)

Sarcocystis infections have been reported from the African buffalo (Syncerus caffer), but the species have not been named. Here we propose a new name Sarcocystis cafferi from the African buffalo. Histological examination of heart (92), skeletal muscle (36), and tongue (2) sections from 94 buffalos from the Greater Kruger National Park, South Africa, and a review of the literature revealed only 1 species of Sarcocystis in the African buffalo. Macrocysts were up to 12 mm long and 6 mm wide and were located in the neck muscles and overlying connective tissue. They were pale yellow; shaped like a lychee fruit stone or cashew nut; turgid or flaccid and oval to round (not fusiform). By light microscopy (LM) the sarcocyst wall was relatively thin. By scanning electron microscopy (SEM), the sarcocyst wall had a mesh-like structure with irregularly shaped villar protrusions (vp) that were of different sizes and folded over the sarcocyst wall. The entire surfaces of vp were covered with papillomatous structures. By transmission electron microscopy (TEM), the sarcocyst wall was up to 3.6 lm thick and had highly branched villar protrusions that were up to 3 lm long. The villar projections contained filamentous tubular structures, most of which were parallel to the long axis of the projections, but some tubules criss-crossed, especially at the base. Granules were absent from these tubules. Longitudinally cut bradyzoites were 12.132.7 lm in size, had a long convoluted mitochondrion, and only 2 rhoptries. Phylogenetic analysis of 18S rRNA and cytochrome C oxidase subunit 1 (cox1) gene sequences indicated that this Sarcocystis species is very closely related to, but distinct from, Sarcocystis fusiformis and Sarcocystis hirsuta. Thus, morphological findings by LM, SEM, and TEM together with molecular phylogenetic data (from 18S rRNA and cox1) confirm that the Sarcocystis species in the African buffalo is distinct from S. fusiformis and has therefore been named Sarcocystis cafferi.http://digitalcommons.unl.edu/jrnlparasitology/hb201

Social learning in LEADER: Exogenous, endogenous and hybrid evaluation in rural development

This paper considers the relationship between the centralised exogenous, institutions and the embedded, endogenous institutions of rural governance in Europe through an examination the evaluation procedures of the European LEADER programme. LEADER is presented in the literature as progressive in terms of innovation and stakeholder engagement. Yet while the planning and management of LEADER embraces heterogeneity and participation, programmatic evaluation is centralised and held at arms length from delivery organisations. The paper reviews previous efforts to improve evaluation in LEADER and considers alternative strategies for evaluation, contrasting LEADER practice with participatory evaluation methodologies in the wider international context. Can evaluation in itself be valuable as a mode of social learning and hence a driver for endogenous development in rural communities in Europe? The paper concludes by examining the challenges in producing a hybrid form of evaluation which accommodates endogenous and exogenous values

Recent Semen Exposure Impacts the Cytokine Response and Bacterial Vaginosis in Women

BackgroundThe presence of semen in the vagina from unprotected sex may influence the immune and microbial environment of the female genital tract. Inflammatory cytokine concentrations and BV-associated bacteria in female genital secretions may influence HIV risk, although the effect of recent sexual intercourse on incident BV and the cytokine milieu of cervicovaginal secretions has rarely been measured in previous studies. Here, we investigated the extent to which partner semen impacts the cytokine response and incident BV.MethodsAt baseline, we assessed the recency of semen exposure in menstrual cup supernatants by quantifying prostate specific antigen (PSA) levels using ELISA in 248 HIV-uninfected women at high risk for HIV infection. Luminex was used to measure 48 cytokines in menstrual cup supernatants and vaginal swabs to diagnose BV by Nugent score. Point-of-care screening for Chlamydia trachomatis and Neisseria gonorrhoeae was conducted using GeneXpert while OSOM was used for Trichomonas vaginalis detection. Multivariable models, adjusted for age, sexually transmitted infections, BV, current contraception use and condom use, were used to assess the impact of semen exposure on biomarkers of inflammation and BV.ResultsPresence of PSA, indicating recent semen exposure within 48 hours prior to sampling, was observed in menstrual cup supernatants of 17% (43/248) of women. Of these women, 70% (30/43) had self-reported condom use at their last sex act and 84% (36/43) had BV (Nugent score &gt;7). PSA presence was significantly associated with prevalent BV (Relative Risk (RR), 2.609; 95% Confidence Interval (CI), 1.104 - 6.165; p = 0.029). Furthermore, women with detectable PSA had high median concentrations of macrophage inflammatory protein- beta (MIP-1α, p=0.047) and low median concentration of the stem cell growth factor beta (SCGF-β, p=0.038) compared to those without PSA.ConclusionA degree of discordance between self-reports of consistent condom use and PSA positivity was observed. There was also evidence of a relationship between recent semen exposure, BV prevalence and altered cytokine concentrations. These findings suggest that PSA, as a semen biomarker, should be taken into consideration when investigating biological markers in the female genital tract and self-reported condom use in studies on reproductive and sexual health

Towards Room Temperature Thermochromic Coatings with controllable NIR-IR modulation for solar heat management & smart windows applications

Solar heat management & green air-conditioning are among the major technologies that could mitigate heat islands phenomenon while minimizing significantly the CO2 global foot-print within the building & automotive sectors. Chromogenic materials in general, and thermochromic smart coatings especially are promising candidates that consent a noteworthy dynamic solar radiation Infrared (NIR-IR) regulation and hence an efficient solar heat management especially with the expected increase of the global seasonal temperature. Within this contribution, two major challenging bottlenecks in vanadium oxide based smart coatings were addressed. It is validated for the first time that the NIR-IR modulation of the optical transmission (∆TTRANS = T(T〈TMIT) − T(T〉TMIT) of Vanadium oxide based smart coatings can be controlled & tuned. This upmost challenging bottle-neck controllability/tunability is confirmed via a genuine approach alongside to a simultaneous drastic reduction of the phase transition temperature TMIT from 68.8 °C to nearly room temperature. More precisely, a substantial thermochromism in multilayered V2O5/V/V2O5 stacks equivalent to that of standard pure VO2 thin films but with a far lower transition temperature, is reported. Such a multilayered V2O5/V/V2O5 thermochromic system exhibited a net control & tunability of the optical transmission modulation in the NIR-IR (∆TTRANS) via the nano-scaled thickness’ control of the intermediate Vanadium layer. In addition, the control of ∆TTRANS is accompanied by a tremendous diminution of the thermochromic transition temperature from the elevated bulk value of 68.8 °C to the range of 27.5–37.5 ºC. The observed remarkable and reversible thermochromism in such multilayered nano-scaled system of V2O5/V/V2O5 is likely to be ascribed to a noteworthy interfacial diffusion, and an indirect doping by alkaline ions diffusing from the borosilicate substrate. It is hoped that the current findings would contribute in advancing thermochromic smart window technology and their applications for solar heat management in glass windows in general, skyscraper especially & in the automotive industry. If so, this would open a path to a sustainable green air-conditioning with zero-energy input
