Sleep Health amongst Patients Attending Adult Neurology Clinic in Abakaliki, Nigeria.

BACKGROUND: Sleep health indicates how well an individual or population sleeps. Good sleep health is characterized by subjective satisfaction, sustained alertness during waking hours, appropriate timing, high efficiency, and adequate duration. Poor sleep health is associated with many short-term and long-term health consequences. There are limited data on the pattern of sleep health in Nigeria. Against this backdrop, we embarked on this study to determine the Pattern of Sleep Health among patients attending the Adult Neurology clinic in a Federal Teaching Hospital, in Abakaliki, Nigeria. METHODS: This is a cross-sectional observational hospital-based study undertaken at the Adult Neurology clinic of the Alex Ekwueme Federal University Teaching Hospital Abakaliki, Nigeria from July to September 2022. RESULTS: Out of the 267 patients recruited for the study, 19% had good sleep health with SATED scores of 8 to 10 while 81% had poor sleep health. The absence of alcohol abuse, cigarette smoking, and neurological diagnosis were statistically associated with poor sleep health with no sex and age predilection. The mean sleep duration was 7.5± 1.5 hours (male = 7.6 hours, female = 7.3 hours, 18- 64 years= 7.4 hours, ≥ 65 years =7.9 hours). Timing of sleep (mean= 0.97) was the least rated while sleep satisfaction (mean= 1.54) was the best-rated sleep dimension. CONCLUSION: Sleep health is very poor amongst patients attending the adult Neurology clinic at Abakaliki Nigeria and it is associated with smoking, absence of alcohol abuse, and neurological diagnosis. CONTEXTE: La santé du sommeil indique à quel point un individu ou une population dort. Une bonne santé du sommeil se caractérise par une satisfaction subjective, une vigilance soutenue pendant les heures d'éveil, un timing approprié, une efficacité élevée et une durée adéquate. Une mauvaise santé du sommeil est associée à de nombreuses conséquences sanitaires à court et à long terme. Il existe des données limitées sur le schéma de santé du sommeil au Nigéria. Dans ce contexte, nous avons entrepris cette étude pour déterminer le schéma de santé du sommeil parmi les patients fréquentant la clinique de neurologie pour adultes dans un hôpital d'enseignement fédéral à Abakaliki, Nigeria. MÉTHODES: Il s'agissait d'une étude observationnelle transversale réalisée à la clinique de neurologie pour adultes de l'hôpital universitaire fédéral Alex Ekwueme àAbakaliki, Nigeria, de juillet à septembre 2022. RÉSULTATS: Sur les 267 patients recrutés pour l'étude, 19 % avaient une bonne santé du sommeil avec des scores SATED de 8 à 10, tandis que 81 % avaient une mauvaise santé du sommeil. L'absence d'abus d'alcool, de tabagisme et de diagnostic neurologique était statistiquement associée à une mauvaise santé du sommeil, sans prédilection pour le sexe et l'âge. La durée moyenne du sommeil était de 7,5 ± 1,5 heures (homme = 7,6 heures, femme = 7,3 heures, 18-64 ans = 7,4 heures, ≥ 65 ans = 7,9 heures). Le timing du sommeil (moyenne = 0,97) était la dimension la moins bien notée, tandis que la satisfaction du sommeil (moyenne = 1,54) était la dimension la mieux notée. CONCLUSION: La santé du sommeil est très mauvaise chez les patients fréquentant la clinique de neurologie pour adultes à Abakaliki, au Nigéria, et elle est associée au tabagisme, à l'absence d'abus d'alcool et au diagnostic neurologique.

Effectiveness of an online module: climate-change and sustainability in clinical practice.

BACKGROUND: Climate change has significant implications for health, yet healthcare provision itself contributes significant greenhouse gas emission. Medical students need to be prepared to address impacts of the changing environment and fulfil a key role in climate mitigation. Here we evaluate the effectiveness of an online module on climate-change and sustainability in clinical practice designed to achieve learning objectives adapted from previously established sustainable healthcare priority learning outcomes. METHODS: A multi-media, online module was developed, and 3rd and 4th year medical students at Brighton and Sussex Medical School were invited to enrol. Students completed pre- and post-module questionnaires consisting of Likert scale and white space answer questions. Quantitative and qualitative analysis of responses was performed. RESULTS: Forty students enrolled and 33 students completed the module (83% completion rate). There was a significant increase in reported understanding of key concepts related to climate change and sustainability in clinical practice (p < 0.001), with proportion of students indicating good or excellent understanding increasing from between 2 - 21% students to between 91 - 97% students. The majority (97%) of students completed the module within 90 min. All students reported the module was relevant to their training. Thematic analysis of white space responses found students commonly reported they wanted access to more resources related to health and healthcare sustainability, as well as further guidance on how to make practical steps towards reducing the environmental impact within a clinical setting. CONCLUSION: This is the first study to evaluate learner outcomes of an online module in the field of sustainable health and healthcare. Our results suggest that completion of the module was associated with significant improvement in self-assessed knowledge of key concepts in climate health and sustainability. We hope this approach is followed elsewhere to prepare healthcare staff for impacts of climate change and to support improving the environmental sustainability of healthcare delivery.

UK medical students' perspectives on practical prescribing teaching and learning provisions: a cross-sectional survey.

PURPOSE: To determine medical students' perspectives on the provision for the teaching and learning of processes that lead to and include the writing of a clear, safe and legal prescription (practical prescribing) in UK medical schools. METHODS: We designed a cross-sectional survey of UK medical students in years three, four and five. Students were asked about their experiences and views of practical prescribing teaching and learning they had encountered on their medical course. RESULTS: A total of 1023 medical students responded (7% response rate), from 25 UK medical schools: 22%, 37% and 41% in the third, fourth and final years, respectively. Teaching of practical prescribing was widespread, with 94.3% of final year (n = 396, 95% confidence interval [CI] = 92-97%), 86.8% of fourth year (n = 328, CI = 83-90%) and 73.8% of third year (n = 166, CI = 67-80%) students reporting they had received it. Availability of this teaching appeared to vary by medical school. Self-directed learning was the most frequently reported mode of delivery (90.9%, n = 809). Validated pre-prescribing and simulation were perceived by students in each year group as the most effective methods. Clinical pharmacologists, clinical pharmacists and junior doctors were perceived by the students as being the most effective professional groups at teaching practical prescribing. CONCLUSIONS: UK medical students reported a variety of methods utilised in the teaching and learning of practical prescribing. However, methods they perceived to be very effective (simulation and pre-prescribing) do not appear to be widely available or are only reserved for the final year of study. Combining such methods with involvement of professional groups perceived to be most effective should be explored.

Pharmacology and Therapeutics Education in the European Union Needs Harmonization and Modernization: A Cross-sectional Survey Among 185 Medical Schools in 27 Countries.

Effective teaching in pharmacology and clinical pharmacology and therapeutics (CPT) is necessary to make medical students competent prescribers. However, the current structure, delivery, and assessment of CPT education in the European Union (EU) is unknown. We sent an online questionnaire to teachers with overall responsibility for CPT education in EU medical schools. Questions focused on undergraduate teaching and assessment of CPT, and students' preparedness for prescribing. In all, 185 medical schools (64%) from 27 EU countries responded. Traditional learning methods were mainly used. The majority of respondents did not provide students with the opportunity to practice real-life prescribing and believed that their students were not well prepared for prescribing. There is a marked difference in the quality and quantity of CPT education within and between EU countries, suggesting that there is considerable scope for improvement. A collaborative approach should be adopted to harmonize and modernize the undergraduate CPT education across the EU.

Reciprocal regulation of human soluble and particulate guanylate cyclases in vivo.

BACKGROUND & PURPOSE: We demonstrated previously that reciprocal regulation of soluble (sGC) and particulate (pGC) guanylate cyclases by NO and natriuretic peptides coordinates cyclic cGMP-mediated vasodilatation in vitro. Herein, we investigated whether such an interaction contributes to vascular homeostasis in mice and humans in vivo. EXPERIMENTAL APPROACH: Mean arterial blood pressure (MABP) changes in anaesthetized mice were monitored in response to i.v. administration of cGMP- and cAMP-dependent vasodilators in wild-type (WT), endothelial NO synthase (eNOS) and natriuretic peptide receptor (NPR)-A knockout mice. Forearm blood flow (FBF) in response to intra-brachial infusion of ANP (25, 50, 100, 200 pmol min(-1)) in the absence and presence of the NOS inhibitor NG-methyl-L-arginine (L-NMA; 4 micromol min(-1)) and the control constrictor noradrenaline (240 pmol min(-1)) was assessed in healthy volunteers. KEY RESULTS: Sodium nitroprusside (SNP; NO-donor) and atrial natriuretic peptide (ANP) produced dose-dependent reductions in MABP in WT animals that were significantly enhanced in eNOS KO mice. In NPR-A K mice, SNP produced a dose-dependent reduction in MABP that was significantly greater than that in WT mice. Responsiveness to the cAMP-dependent vasodilator epoprostenol was similar in WT, eNOS KO and NPR-A KO animals. ANP caused vasodilatation of the forearm resistance vasculature that was significantly greater in individuals lacking endothelium-derived NO (i.e. L-NMA treated). CONCLUSIONS & IMPLICATIONS: These data demonstrate that crosstalk occurs between the NO-sGC and ANP-pGC pathways to regulate cGMP-dependent vasodilatation in vivo in both mice and humans. These findings have implications for understanding the link between natriuretic peptide activity and cardiovascular risk.

The use of self-expandable metal stents in the palliation of malignant bowel obstruction.

Palliation of malignant gastrointestinal obstruction is a major aspect of oncology. We assessed the efficacy of stents in the palliation of gastric outlet, duodenal and colonic obstruction. We undertook a retrospective study of 35 consecutive patients who were referred for stent insertion with palliative intent from June, 1999 to March, 2003. Thirty-two stents were successfully placed in 30 patients. Technical success rate was 86% (30/35 patients). Of the patients who had successful insertion, 83% had complete relief of symptoms. In 1 patient the stent failed to expand. There was no procedure related mortality. Median survival was 1.6 months (range, 0-14.8). The conclusion was that self-expandable metal stents provide an effective method of palliation in malignant gastrointestinal obstruction, with high clinical and technical success rates and low complication rates.

Infantile hypertrophic pyloric stenosis--diagnosis from the pyloric muscle index.

Measurements of pyloric length, diameter and muscle thickness were made from ultrasound images of 39 babies, 21 of whom were subsequently found at operation to have infantile hypertrophic pyloric stenosis. From these measurements, the volume of pyloric muscle in cm3 was estimated for each case and divided by the body weight in kilograms. The resulting pyloric muscle index proved to be a much more reliable guide to the diagnosis of pyloric stenosis than any of the individual measurements or the volume estimation alone.
