The Fauna Biodiversity of Ikot Ondo Community Forest in Essien Udim L. G. A. of Akwa Ibom State, South Eastern Nigeria

Prolonged deforestation, poaching and wildlife habitat loss has been a serious threat to wildlife conservation in Nigeria, thereby endangering fauna diversity resources in the country. This study was carried out to determine the population estimate of wild fauna in the communal land of Ikot Ondo Community forest in Essien Udim L. G. A. of Akwa Ibom State. The forest is situated in a rainforest ecosystem surrounded by villages whose source of livelihood is mainly through exploitation of the forest resources. The study showed the avifauna species to be more abundant with species indices of -1.2985 and 11.6246 respectively when compared with those of mammals (-1.1914 and 12.5174), amphibian and reptiles (-1.0441 and 8.4831) and the insect species (-1.1357 and 6.5977). The mammals, amphibian and the reptile species were largely depleted as a result of over exploitation. Participatory resources management between the various stakeholders is therefore recommended to ensure the sustainable conservation of wildlife resources in the area.Keywords: Biodiversity, Conservation, Community Forest, Participatory managemen

General practitioner reported follow–up visits among asthma patients in North Central Nigeria

Background: Despite the benefits of regular follow–up in the long–term care of asthma, no previous study has reported on it among asthma patients in Nigeria. Objective: This survey was designed to evaluate GP–reported follow–up visits among asthma patients in North Central Nigeria. Methods: It was a cross–sectional survey conducted among GPs in three North Central states of Nigeria. Results: Overall, 48.3% of the GPs reported that their patients usually come for follow-up visits. About 63.6%, 40.0%, and 55.3% of the GPs in Kwara, Kogi, and Niger states, respectively, reported that their patients came for follow–up visits in the month prior to this study. Less than two–third of GPs in both private (55.1%) and public (56.8%) hospitals reportedly attended to patients on follow–up visits. About 46.5%, 37.5%, and 52.0% of the GPs who attended to patients 2 weeks prior to the study reported that their patients came for follow–up visits. There was signifi cant difference (P = 0.04) in the reported follow–up visits by GPs who attended to ≥ 10 asthma patients compared to others. None of the nine GPs who reportedly treated ≥ 10 patients in the preceding month of the study attended to any patient on follow–up visits. Conclusion: The GP–reported rates of follow–up visits in patients that are accessing asthma care from GPs practicing in the North Central part of Nigeria are low. Further studies to identify barriers to follow–up visits and how to correct them are therefore recommended.Keywords: Asthma care, follow—up visits general practitioners, NigeriaArrière-plan: Malgré les avantages de suivi régulier–jusqu’à long - term care de l’asthme, aucune étude antérieure n’a signalé sur elle chez les patients asthmatiques au Nigeria. Objectif: Ce sondage a été conçu pour évaluer les GP–signalés suivi–visites chez les patients asthmatiques au Centre Nord du Nigéria. Méthodes: C’est une croix–sectionnelle enquête menée parmi les GPs dans trois États centrale du Nord du Nigéria. Résultats: Dans l’ensemble, 48,3% des GPs a signalé que les patients sont en général pour des visites de suivi. 63,6% Environ, 40,0% 55,3% des GPs dans les États Kwara, Kogi et au Niger, respectivement, rapporte et que leurs patients sont venus pour suivi–visites dans le mois précédant cette étude. Moins de deux - tiers des GPs dans les hôpitaux publics (56,8%) et le privé (55,1%) auraient été assisté aux patients sur suivi–visites. Environ 46,5%, 37,5% et 52,0% le GPS qui ont participé aux patients 2 semaines avant l’étude rapporte que leurs patients sont venus pour suivi–visites. Il y avait une différence signifi cative (P = 0,04) dans le suivi déclaré–up visites par GPs qui ont participé à ≥ 10 patients asthmatiques par rapport aux autres. Aucun des neuf GPs qui auraient été traités ≥ 10 patients dans le mois précédent de l’étude ont assisté à tout patient sur suivi–visites. Conclusion: Le GP–taux signalés de suivi–visites chez les patients qui sont à accéder aux soins de l’asthme de GPs pratiquant dans la partie centrale du Nord du Nigéria sont faibles. D’autres études pour identifi er les obstacles à suivre–visites et comment à correct eux sont donc recommandés.Mots clés: L’asthme care, suivre — up généralistes, des visites, Nigeri

Perception of Simulation‑based Learning among Medical Students in South India

Background: Traditional methods of educating medical students are no longer sufficient in the current era largely influenced by multimedia. Simulation‑based techniques may play a pivotal role in bridging this educational gap.Aim: This study was conducted to explore the perception of medical students towards simulation‑based learning (SBL).Subjects and Methods: This cross‑sectional study was conducted in May 2013 in a private medical college in Mangalore, Karnataka, India. A total of 247 participants from fourth, sixth, eighth semester and internship were chosen by convenience sampling method. Attitudinal data on perception towards SBL were collected using a self‑administered questionnaire with responses in a 5‑point Likert’s scale.Results: The mean age of students was 21.3 (standard deviation 1.9) years, and males constituted 55.5% (137/247). Most participants 72.5% (179/247) had favorable perceptions of SBL, with scores of92–118 out of a possible 118 points. Favorable perception towards SBL was seen significantly more among female students (P = 0.04) and senior MBBS students of sixth and eighth semesters (P = 0.05). Nearly, all students (90.7%; 224/247) agreed that simulation supports the development of clinical skills. As many as 29.6% (73/247) agreed that real patients might be replaced with simulated patients in practical examinations.Conclusion: SBL was perceived as favorable by a large number of participants in this study indicating a bright prospect for its implementation in the medical curriculum. Keywords: Interns, Medical students, Perception, Simulation‑based learnin

Death, dying and informatics: misrepresenting religion on MedLine

BACKGROUND: The globalization of medical science carries for doctors worldwide a correlative duty to deepen their understanding of patients' cultural contexts and religious backgrounds, in order to satisfy each as a unique individual. To become better informed, practitioners may turn to MedLine, but it is unclear whether the information found there is an accurate representation of culture and religion. To test MedLine's representation of this field, we chose the topic of death and dying in the three major monotheistic religions. METHODS: We searched MedLine using PubMed in order to retrieve and thematically analyze full-length scholarly journal papers or case reports dealing with religious traditions and end-of-life care. Our search consisted of a string of words that included the most common denominations of the three religions, the standard heading terms used by the National Reference Center for Bioethics Literature (NRCBL), and the Medical Subject Headings (MeSH) used by the National Library of Medicine. Eligible articles were limited to English-language papers with an abstract. RESULTS: We found that while a bibliographic search in MedLine on this topic produced instant results and some valuable literature, the aggregate reflected a selection bias. American writers were over-represented given the global prevalence of these religious traditions. Denominationally affiliated authors predominated in representing the Christian traditions. The Islamic tradition was under-represented. CONCLUSION: MedLine's capability to identify the most current, reliable and accurate information about purely scientific topics should not be assumed to be the same case when considering the interface of religion, culture and end-of-life care

Closing the sea surface mixed layer temperature budget from in situ observations alone: Operation Advection during BoBBLE

Sea surface temperature (SST) is a fundamental driver of tropical weather systems such as monsoon rainfall and tropical cyclones. However, understanding of the factors that control SST variability is lacking, especially during the monsoons when in situ observations are sparse. Here we use a ground-breaking observational approach to determine the controls on the SST variability in the southern Bay of Bengal. We achieve this through the first full closure of the ocean mixed layer energy budget derived entirely from in situ observations during the Bay of Bengal Boundary Layer Experiment (BoBBLE). Locally measured horizontal advection and entrainment contribute more significantly than expected to SST evolution and thus oceanic variability during the observation period. These processes are poorly resolved by state-of-the-art climate models, which may contribute to poor representation of monsoon rainfall variability. The novel techniques presented here provide a blueprint for future observational experiments to quantify the mixed layer heat budget on longer time scales and to evaluate these processes in models

Differential expression analysis with global network adjustment

<p>Background: Large-scale chromosomal deletions or other non-specific perturbations of the transcriptome can alter the expression of hundreds or thousands of genes, and it is of biological interest to understand which genes are most profoundly affected. We present a method for predicting a gene’s expression as a function of other genes thereby accounting for the effect of transcriptional regulation that confounds the identification of genes differentially expressed relative to a regulatory network. The challenge in constructing such models is that the number of possible regulator transcripts within a global network is on the order of thousands, and the number of biological samples is typically on the order of 10. Nevertheless, there are large gene expression databases that can be used to construct networks that could be helpful in modeling transcriptional regulation in smaller experiments.</p> <p>Results: We demonstrate a type of penalized regression model that can be estimated from large gene expression databases, and then applied to smaller experiments. The ridge parameter is selected by minimizing the cross-validation error of the predictions in the independent out-sample. This tends to increase the model stability and leads to a much greater degree of parameter shrinkage, but the resulting biased estimation is mitigated by a second round of regression. Nevertheless, the proposed computationally efficient “over-shrinkage” method outperforms previously used LASSO-based techniques. In two independent datasets, we find that the median proportion of explained variability in expression is approximately 25%, and this results in a substantial increase in the signal-to-noise ratio allowing more powerful inferences on differential gene expression leading to biologically intuitive findings. We also show that a large proportion of gene dependencies are conditional on the biological state, which would be impossible with standard differential expression methods.</p> <p>Conclusions: By adjusting for the effects of the global network on individual genes, both the sensitivity and reliability of differential expression measures are greatly improved.</p&gt
