Disaster content in Australian tertiary postgraduate emergency nursing courses: a survey
Background Emergency nurses play a pivotal role in disaster relief during the response to, and recovery of both in-hospital and out-of-hospital disasters. Postgraduate education is important in preparing and enhancing emergency nurses' preparation for disaster nursing practice. The disaster nursing content of Australian tertiary postgraduate emergency nursing courses has not been compared across courses and the level of agreement about suitable content is not known. Aim To explore and describe the disaster content in Australian tertiary postgraduate emergency nursing courses. Method A retrospective, exploratory and descriptive study of the disaster content of Australian tertiary postgraduate emergency nursing courses conducted in 2009. Course convenors from 12 universities were invited to participate in a single structured telephone survey. Data was analysed using descriptive statistics. Results Ten of the twelve course convenors from Australian tertiary postgraduate emergency nursing courses participated in this study. The content related to disasters was varied, both in terms of the topics covered and duration of disaster content. Seven of these courses included some content relating to disaster health, including types of disasters, hospital response, nurses' roles in disasters and triage. The management of the dead and dying, and practical application of disaster response skills featured in only one course. Three courses had learning objectives specific to disasters. Conclusion The majority of courses had some disaster content but there were considerable differences in the content chosen for inclusion across courses. The incorporation of core competencies such as those from the International Council of Nurses and the World Health Organisation, may enhance content consistency in curriculum. Additionally, this content could be embedded within a proposed national education framework for disaster health.No Full Tex

First aid knowledge retention in school children: A review of the literature
Introduction First aid training for lay people is recognised as an important capacity building component of pre-hospital care in communities. In countries such as Australia, this training is increasingly targeted to school children, but relatively little attention is directed to knowledge retention or optimal training methods for this population. This literature review aimed to determine whether the published literature demonstrates that first aid knowledge is retained by school children who have learnt first aid from professional first aid providers. Methods A systematic search of the peer-reviewed and grey literature was conducted for narrative review. Journal articles were retrieved from three databases (MEDLINE, CINAHL, ERIC) using the search terms ‘first aid’; ‘resuscitation’; ‘training’; ‘child*’; and ‘school’. Inclusion and exclusion criteria were applied and review findings organised thematically. Results The search yielded four primary studies of European school children aged between 4 and 12 years trained by professional first aid providers. Subsequent review identified emergent themes of Resuscitative first aid and Non-resuscitative first aid. Heterogeneity was apparent in training and evaluation methods, and study quality varied. Reported first aid knowledge retention was mixed. Conclusion There is a lack of quality evidence to guide optimal training methods and maximise first aid knowledge retention in school children. To date, research in this area has been limited to Europe. Further research is therefore recommended. Formal evaluation of professional first aid training can help guide training methods and enhance first aid knowledge retention in school children, thereby building more robust first aid capacity in the community
Comparative Analysis of MLP, CNN, and RNN Models in Automatic Speech Recognition: Dissecting Performance Metric
This study conducts a comparative analysis of three prominent machine learning models: Multi-Layer Perceptrons (MLP), Convolutional Neural Networks (CNN), and Recurrent Neural Networks (RNN) with Long Short-Term Memory (LSTM) in the field of automatic speech recognition (ASR). This research is distinct in its use of the LibriSpeech 'test-clean' dataset, selected for its diversity in speaker accents and varied recording conditions, establishing it as a robust benchmark for ASR performance evaluation. Our approach involved preprocessing the audio data to ensure consistency and extracting Mel-Frequency Cepstral Coefficients (MFCCs) as the primary features, crucial for capturing the nuances of human speech. The models were meticulously configured with specific architectural details and hyperparameters. The MLP and CNN models were designed to maximize their pattern recognition capabilities, while the RNN (LSTM) was optimized for processing temporal data. To assess their performance, we employed metrics such as precision, recall, and F1-score. The MLP and CNN models demonstrated exceptional accuracy, with scores of 0.98 across these metrics, indicating their effectiveness in feature extraction and pattern recognition. In contrast, the LSTM variant of RNN showed lower efficacy, with scores below 0.60, highlighting the challenges in handling sequential speech data. The results of this study shed light on the differing capabilities of these models in ASR. While the high accuracy of MLP and CNN suggests potential overfitting, the underperformance of LSTM underscores the necessity for further refinement in sequential data processing. This research contributes to the understanding of various machine learning approaches in ASR and paves the way for future investigations. We propose exploring hybrid model architectures and enhancing feature extraction methods to develop more sophisticated, real-world ASR systems. Additionally, our findings underscore the importance of considering model-specific strengths and limitations in ASR applications, guiding the direction of future research in this rapidly evolving field

Characterization of malaria vectors in Huye District, Southern Rwanda
Background: Effective control of malaria requires knowledge of vector species, their feeding and resting behaviour as well as breeding habitats. The objective of this study was to determine malaria vector species abundance and identify their larval habitats in Huye district, southern Rwanda.Methods: Adult mosquitoes were collected indoors using light trap and pyrethrum spray catch techniques, and outdoors using light traps. Female Anopheles mosquitoes were identified to species level by morphological characteristics. Enzyme-linked Immunosorbent Assay (ELISA) was used to screen for Plasmodium falciparum circumsporozoite protein and host blood meal sources. Anopheles larvae were sampled using dippers and raised into adult mosquitoes which were identified morphologically.Results: Anopheles gambiae sensu lato comprised of 70% of the 567 Anopheles collected. Other Anopheles species identified were An. funestus 4%, An. squamosus 16.5%, An. maculipalpis 6.5%, An. ziemanni 1.7%, An. pharoensis 1.2 % and An. coustani 0.1%. The majority, 63.5% of the collected mosquitoes were from indoors collections. The overall human blood index was 0.509. The P. falciparum circumsporozoite protein was found in 11 mosquitos including 8 Anopheles gambiae s.l. and 3 secondary vectors out of the 567 tested. The overall sporozoite rate was 1.9%. A total of 661 Anopheline larvae from 22 larval habitats were collected. They comprised of An. gambiae s.l. (89%) and An. ziemanni (11%). The absolute breeding index was 86.4%. The most common larval habitats were in full sunlight with still water like rice paddies and pools of stagnant water.Conclusion: These findings show that Anopheles gambiae s.l. is the dominant malaria vector in the area with other vectors playing a secondary role in malaria transmission. Malaria interventions need to be strengthened to reduce even further the malaria transmission in the area.
Genetic diversity and population structure of Fasciola gigantica isolated from cattle in Malawi
Fasciola gigantica is an important trematode that affects the health of animals and humans in tropical and subtropical countries, including Malawi. Information on the genetic diversity and population structure of F. gigantica is important to understanding the parasite`s transmission patterns/ and in monitoring the development of resistance to commonly used anthelmintic agents. This study aimed to analyze the genetic diversity and population structure of Fasciola species collected from cattle at slaughter slabs and abattoirs in selected districts of Malawi. A total of 27 adult liver flukes were collected from cattle at slaughter slabs and abattoirs in the northern region (n = 12), central region (n = 5), and southern region (n = 10). The mitochondrial cytochrome c oxidase I (COI) gene and nicotinamide adenine dinucleotide dehydrogenase 1 (ND1) gene were amplified and the amplicons were sequenced for all samples. The sequences obtained were used to investigate genetic diversity through median-joining networks and phylogenetic analysis. Tajima’s D test and Fu’s Fs statistics were used to determine the population structure. Based on the analyzed COI and ND1 sequences, all samples were identified as F. gigantica. Single nucleotide polymorphisms (SNPs) were identified at 18 and 17 positions for COI and ND1 genes, resulting in 10 and 5 haplotypes, respectively. The haplotype diversities were 0.867 and 0.479 for COI and ND1 gene sequences, respectively. The population genetic structure indices showed a population that has undergone a recent expansion. This study provides baseline epidemiological data on the genetic diversity and population structure of F. gigantica in Malawi; which is important for its control.</p
