    Abstract Outcomes after out-of-hospital cardiac arrest (OHCA) remain poor in the UK. In order to increase the chances of successful resuscitation, international society guidelines on cardiopulmonary resuscitation quality have recommended titration of chest compression parameters and vasopressor administration to arterial diastolic blood pressure if invasive catheters are in situ at the time of cardiac arrest. However, prehospital initiation of arterial and central venous catheterisation is seldom undertaken due to the risks and significant technical challenges in the context of ongoing resuscitation in this environment. In 2019, a dedicated programme was started at East Anglian Air Ambulance (EAAA) to enable the safe introduction of contemporary emergency vascular access devices, in order to improve physiological monitoring intra-arrest and deliver nuanced, goal-directed resuscitation in OHCA patients. This programme was entitled Specialist Percutaneous Emergency Aortic Resuscitation (SPEAR). This article details the EAAA SPEAR technique; and the development, implementation and governance of this novel endovascular strategy in our UK physician-paramedic staffed helicopter emergency medical service.

    Abstract Background: This study aimed to determine the rate of scalpel cricothyroidotomy conducted by a physician-paramedic prehospital trauma service over 20 years and to identify indications for, and factors associated with the intervention.
    Methods: A retrospective observational study was conducted from 1 January 2000 to 31 December 2019 using clinical database records. This study was conducted in a physician-paramedic prehospital trauma service, serving a predominantly urban population of approximately 10 million in an area of approximately 2500 km
    Results: Over 20 years, 37 725 patients were attended by the service, and 72 patients received a scalpel cricothyroidotomy. An immediate 'primary' cricothyroidotomy was performed in 17 patients (23.6%), and 'rescue' cricothyroidotomies were performed in 55 patients (76.4%). Forty-one patients (56.9%) were already in traumatic cardiac arrest during cricothyroidotomy. Thirty-two patients (44.4%) died on scene, and 32 (44.4%) subsequently died in hospital. Five patients (6.9%) survived to hospital discharge, and three patients (4.2%) were lost to follow-up. The most common indication for primary cricothyroidotomy was mechanical entrapment of patients (n=5, 29.4%). Difficult laryngoscopy, predominantly due to airway soiling with blood (n=15, 27.3%) was the most common indication for rescue cricothyroidotomy. The procedure was successful in 97% of cases. During the study period, 6570 prehospital emergency anaesthetics were conducted, of which 30 underwent rescue cricothyroidotomy after failed tracheal intubation (0.46%, 95% CI 0.31% to 0.65%).
    Conclusions: This study identifies a number of indications leading to scalpel cricothyroidotomy both as a primary procedure or after failed intubation. The main indication for scalpel cricothyroidotomy in our service was as a rescue airway for failed laryngoscopy due to a large volume of blood in the airway. Despite high levels of procedural success, 56.9% of patients were already in traumatic cardiac arrest during cricothyroidotomy, and overall mortality in patients with trauma receiving this procedure was 88.9% in our service.

    Abstract Background: The King's College London Pre-hospital Care Programme (KCL PCP) is a student-run programme that provides undergraduate medical students with the opportunity to attend observer shifts with the local ambulance service. This study evaluates the contribution of pre-hospital exposure to medical students' clinical and professional development.
    Methods: Students were asked to complete a Likert-scale based survey on self-reported exposure and confidence in various aspects of acute patient assessment, communication and interprofessional education, both before and after the programme; additional qualitative questions querying their experience were asked post-programme. Pre and post-programme Likert-scale responses were matched and statistically analysed, alongside a thematic analysis of qualitative responses.
    Results: Exposure to ambulance service clinicians, confidence assessing acutely unwell patients, and confidence making clinical handovers all increased with statistical significance. Key areas of learning identified from the thematic analysis include increased confidence communicating with patients and families, and an enriched understanding of the work done by pre-hospital clinicians.
    Conclusions: Time spent in the pre-hospital environment shadowing ambulance service clinicians positively contributes to acute care knowledge, inter-personal skills and interprofessional understanding. Rotating medical students through the pre-hospital environment could bridge education gaps in these areas in a manner that complements traditional pre-clinical and clinical teaching.

    Abstract Background: Correctly eliciting and interpreting physical examination (PEx) signs contributes to successful diagnosis and is fundamental to patient care. A significant decline in the time spent acquiring these skills by medical students, and the decreased ability to elicit and recognise signs is widely acknowledged. However, organising teaching to counteract this in the busy clinical environment is challenging. We evaluated the prior exposure to clinical signs, and experience of examination teaching among a cohort of final-year medical students. Following this, we assessed the utility of a structured circuit-based approach (Signs Circuits) using hospital inpatients and junior doctors to provide high-yield PEx teaching and overcome these limitations.
    Materials and methods: Qualitative and quantitative survey feedback, including a standardised list of 62 clinical signs, was sought from final-year medical students during their rotations at a teaching hospital in London, UK, before and after the provision of Signs Circuits.
    Results: Prior to the course the 63 students reported limited exposure to even the most common clinical signs. For example, the murmurs of mitral and tricuspid regurgitation and the sound of lung crackles eluded 43%, 87%, and 32%, respectively. From qualitative feedback, the reasons for this included that much of their prior PEx experience had focused on the performance of appropriate examination steps and techniques in patients without pathology. During the course, students were exposed to an average of 4.4 new signs, and left with increased confidence examining and eliciting signs, and a firmer belief in their importance to diagnosis.
    Conclusion: Medical students continue to have limited exposure to clinical signs in medical school. This signs-focused approach to PEx teaching is an effective and reproducible way to counter the deficiencies identified in signsexposure.

    Abstract A point-of-care ultrasound scan (POCUS) is a core element of the Royal College of Emergency Medicine (RCEM) specialty training curriculum. However, POCUS documentation quality can be poor, especially in the time-pressured environment of the emergency department (ED). A survey of 10 junior ED clinicians at the Princess Royal University Hospital (PRUH) found that total POCUS documentation was as low as 38% in some examinations.This quality improvement project aimed to increase the coverage and quality of POCUS documentation in the ED. This was done by using a plan-do-study-act (PDSA) regime to improve the quality of POCUS documentation from the original baseline to 80%. There were three discreet PDSA cycles and the interventions included improving education and training about POCUS documentation and the introduction of an original proforma, which incorporated six minimum requirements for POCUS documentation as per the joint RCEM and Royal College of Radiologists (RCR) guidelines for POCUS documentation (patient details, indications, findings, conclusions, signature and date).The project team audited the quality of all documented scans in the resuscitation department of the PRUH against the RCEM/RCR guidelines at baseline and following three discrete PDSA cycles. This was done over an 8-week period, spanning 696 attendances to the resuscitation area of the ED and 42 documented POCUS examinations.Quality recording of the six RCEM/RCR elements of POCUS documentation was poor at baseline but improved following three successful PDSA cycles. There was a demonstrated improvement in five of six documentation elements: patient details on POCUS documentation increased from 53.3% to the 66.7%, indication from 60.0% to 66.7%, conclusion from 13.0% to 83.0%, signature from 86.7% to 100.0% and date from 46.7% to 66.7%.These results suggest that the introduction of a proforma and a vigorous education strategy are effective ways to improve the quality of documentation of ED POCUS.

    Abstract Temperature and rainfall have a significant impact on economic growth as well as the outbreak of seasonal diseases in a region. In spite of that inadequate studies have been carried out for analyzing the weather pattern of Bangladesh implementing the artificial neural network. Therefore, in this study, we are implementing a Long Short-term Memory (LSTM) model to forecast the month-wise temperature and rainfall by analyzing 115 years (1901-2015) of weather data of Bangladesh. The LSTM model has shown a mean error of -0.38oC in case of predicting the month-wise temperature for 2 years and -17.64mm in case of predicting the rainfall. This prediction model can help to understand the weather pattern changes as well as studying seasonal diseases of Bangladesh whose outbreaks are dependent on regional temperature and/or rainfall.

    Abstract The world economy as well as public health have been facing a devastating effect caused by the disease termed Coronavirus (COVID-19). A significant step of COVID-19 affected patient9s treatment is the faster and accurate detection of the disease which is the motivation of this study. In this paper, the implementation of a deep transfer learning-based framework using a pre-trained network (ResNet-50) for detecting COVID-19 from the chest X-rays was done. Our dataset consists of 2905 chest X-ray images of three categories: COVID-19 affected (219 cases), Viral Pneumonia affected (1345 cases), and Normal Chest X-rays (1341 cases). The implemented neural network demonstrates significant performance in classifying the cases with an overall accuracy of 96%. Most importantly, the model has shown significantly good performance over the current research-based methods in detecting the COVID-19 cases in the test dataset (Precision = 1.00, Recall = 1.00, F1-score = 1.00, and Specificity = 1.00). Therefore, our proposed approach can be adapted as a reliable method for faster and accurate COVID-19 affected case detection.
