Near-peer teaching and exam results: the acceptability, impact, and assessment outcomes of a novel biological sciences revision programme taught by senior medical students

YesNear-peer teaching is becoming increasingly popular as a learning methodology. We report the development of a novel near-peer biological sciences revision course and its acceptability and impact on student confidence and exam performance. A cross-sectional analysis of tutee-completed evaluation forms before and after each session was performed, providing demographic details, quality scores, and self-rating of confidence in the topic taught on a 0 to 100 mm visual analogue scale (VAS). The confidence data was examined using analysis of means. Exam performance was examined by analysis of variance and canonical correlation analysis. Thirty-eight sessions were delivered to an average of 69.9 (±27.1) years 1 and 2 medical students per session generating 2656 adequately completed forms. There was a mean VAS gain of 19.1 (5.3 to 27.3) in self-reported confidence. Looking at relationship between attendance and exam scores, only two topics showed significant association between number of sessions attended and exam performance, fewer than hypothesised. The present study demonstrates that near-peer teaching for biological sciences is feasible and is associated with improved self-reported confidence in the sessions taught. The outcome data, showing significant effect for only a small number of items, demonstrates the difficulty of outcome related research

Receptionist rECognition and rEferral of Patients with Stroke (RECEPTS) : unannounced simulated patient telephone call study in primary care

Background: Stroke is a leading cause of morbidity and mortality. Timely recognition and referral are essential for treatment. Aim: To examine the ability of receptionists in general practices to recognise symptoms of stroke and direct patients to emergency care. Design and setting: Unannounced simulated patient telephone calls and prospective cross-sectional survey study in general practices in the Birmingham and Solihull area. Method: A total of 52 general practices participated in a total of 520 simulated telephone calls, with 183 receptionists completing questionnaires. Logistic regression analyses were used to examine likelihood of referral for immediate care by ease of vignette recognition and number of common stroke symptoms present. Results: General practice receptionists correctly referred 69% of simulated calls for immediate care. Calls classed as ‘difficult’ to recognise were less likely to be immediately referred. Compared with ‘easy’ calls: ‘difficult’ calls odds ratio (OR) 0.15, 95% confidence interval (CI) = 0.08 to 0.26; ‘moderate’ calls OR 0.55, 95% CI = 0.32 to 0.92. Similarly, calls including one or two ‘FAST’ symptoms were less likely to be referred immediately (compared with three FAST symptoms: one symptom OR 0.30, 95% CI = 0.13 to 0.72; two symptoms OR 0.35, 95% CI = 0.15 to 0.83). Conclusion: General practice receptionists refer patients with stroke for immediate care when they present with several symptoms; however, they are less likely to refer patients presenting with only one symptom or less common symptoms of stroke. Optimum management of acute stroke in primary care requires interventions that improve receptionists’ knowledge of lesser-known stroke symptoms

Receptionist rECognition and rEferral of PaTients with Stroke (RECEPTS) study - protocol of a mixed methods study

BACKGROUND: As the first point of contact for patients and witnesses of stroke, General Practice receptionists can be instrumental in deciding the urgency of clinical contact. Despite the considerable complexity of this task, reception staff are not clinically trained. Minimising the time taken to access thrombolysis is crucial in acute stroke as treatment must be initiated within 4.5 hours of the onset, and the earlier the better, to achieve the best outcomes. Research suggests that patients who first contact their General Practice following the onset of stroke symptoms are less likely to receive thrombolysis, in part due to significant delays within Primary Care.This study therefore aims to understand the role of General Practice receptionists, with particular interest in receptionist's ability to recognise people who may be suffering from a stroke and to handle such patients as a medical emergency. METHODS: The Receptionist rECognition and rEferral of PaTients with Stroke (RECEPTS) study will be a Primary Care based mixed methods study. 60 General Practices in the West Midlands will be recruited. Each practice will receive 10 unannounced simulated patient telephone calls, after the 10 calls questionnaires will be administered to each receptionist. These will examine the behaviour of receptionists towards patients presenting in Primary Care with stroke symptoms, and their knowledge of stroke symptoms. An embedded qualitative study will use interviews and focus groups to investigate the views of General Practice staff on the receptionists' role in patient referral and whether training in this area would be helpful. DISCUSSION: The results of the RECEPTS study will have important implications for providers of Primary Care. The study will establish current practice in UK primary care in terms of General Practice receptionists' knowledge of the presentation and appropriate referral of those who may be suffering a stroke. It will highlight training needs and how such training might be best delivered

Landscape genomics and biased FST approaches reveal single nucleotide polymorphisms under selection in goat breeds of North-East Mediterranean

<p>Abstract</p> <p>Background</p> <p>In this study we compare outlier loci detected using a <it>F<smcaps>ST </smcaps></it>based method with those identified by a recently described method based on spatial analysis (SAM). We tested a panel of single nucleotide polymorphisms (SNPs) previously genotyped in individuals of goat breeds of southern areas of the Mediterranean basin (Italy, Greece and Albania). We evaluate how the SAM method performs with SNPs, which are increasingly employed due to their high number, low cost and easy of scoring.</p> <p>Results</p> <p>The combined use of the two outlier detection approaches, never tested before using SNP polymorphisms, resulted in the identification of the same three loci involved in milk and meat quality data by using the two methods, while the <it>F<smcaps>ST </smcaps></it>based method identified 3 more loci as under selection sweep in the breeds examined.</p> <p>Conclusion</p> <p>Data appear congruent by using the two methods for <it>F<smcaps>ST </smcaps></it>values exceeding the 99% confidence limits. The methods of <it>F<smcaps>ST </smcaps></it>and SAM can independently detect signatures of selection and therefore can reduce the probability of finding false positives if employed together. The outlier loci identified in this study could indicate adaptive variation in the analysed species, characterized by a large range of climatic conditions in the rearing areas and by a history of intense trade, that implies plasticity in adapting to new environments.</p

Microsatellite diversity of the Nordic type of goats in relation to breed conservation: how relevant is pure ancestry?

In the last decades, several endangered breeds of livestock species have been re-established effectively. However, the successful revival of the Dutch and Danish Landrace goats involved crossing with exotic breeds and the ancestry of the current populations is therefore not clear. We have generated genotypes for 27 FAO-recommended microsatellites of these landraces and three phenotypically similar Nordic-type landraces and compared these breeds with central European, Mediterranean and south-west Asian goats. We found decreasing levels of genetic diversity with increasing distance from the south-west Asian domestication site with a south-east-to-north-west cline that is clearly steeper than the Mediterranean east-to-west cline. In terms of genetic diversity, the Dutch Landrace comes next to the isolated Icelandic breed, which has an extremely low diversity. The Norwegian coastal goat and the Finnish and Icelandic landraces are clearly related. It appears that by a combination of mixed origin and a population bottleneck, the Dutch and Danish Land-races are separated from the other breeds. However, the current Dutch and Danish populations with the multicoloured and long-horned appearance effectively substitute for the original breed, illustrating that for conservation of cultural heritage, the phenotype of a breed is more relevant than pure ancestry and the genetic diversity of the original breed. More in general, we propose that for conservation, the retention of genetic diversity of an original breed and of the visual phenotype by which the breed is recognized and defined needs to be considered separately

Ablations of Ghrelin and Ghrelin Receptor Exhibit Differential Metabolic Phenotypes and Thermogenic Capacity during Aging

mice are adaptive. mice.Our data therefore suggest that GHS-R ablation activates adaptive thermogenic function(s) in BAT and increases EE, thereby enabling the retention of a lean phenotype. This is the first direct evidence that the ghrelin signaling pathway regulates fat-burning BAT to affect energy balance during aging. This regulation is likely mediated through an as-yet-unidentified new ligand of GHS-R
