Role of informal healthcare providers in tuberculosis care in low- and middle-income countries: A systematic scoping review.

Achieving targets set in the End TB Strategy is still a distant goal for many Low- and Middle-Income Countries (LMICs). The importance of strengthening public-private partnership by engaging all identified providers in Tuberculosis (TB) care has long been advocated in global TB policies and strategies. However, Informal Healthcare Providers (IPs) are not yet prioritised and engaged in National Tuberculosis Programs (NTPs) globally. There exists a substantial body of evidence that confirms an important contribution of IPs in TB care. A systematic understanding of their role is necessary to ascertain their potential in improving TB care in LMICs. The purpose of this review is to scope the role of IPs in TB care. The scoping review was guided by a framework developed by the Joanna Briggs Institute. An electronic search of literature was conducted in MEDLINE, EMBASE, SCOPUS, Global Health, CINAHL, and Web of Science. Of a total 5234 records identified and retrieved, 92 full-text articles were screened, of which 13 were included in the final review. An increasing trend was observed in publication over time, with most published between 2010-2019. In 60% of the articles, NTPs were mentioned as a collaborator in the study. For detection and diagnosis, IPs were primarily involved in identifying and referring patients. Administering DOT (Directly Observed Treatment) to the patient was the major task assigned to IPs for treatment and support. There is a paucity of evidence on prevention, as only one study involved IPs to perform this role. Traditional health providers were the most commonly featured, but there was not much variation in the role by provider type. All studies reported a positive role of IPs in improving TB care outcomes. This review demonstrates that IPs can be successfully engaged in various roles in TB care with appropriate support and training. Their contribution can support countries to achieve their national and global targets if prioritized in National TB Programs

Joint Power Control and Spreading Gain Optimisation for Minimising the Energy Consumption in CDMA based Ad hoc Networks

This paper addresses the impact of the spreading gain on the efficiency of mobile Ad Hoc networks using Code Division Multiple Access (CDMA) as a mode of transmission. In particular, we concentrate on the trade off between the increase in transmission data rate, hence decrease of transmission time, and the necessary power needed to reach acceptable levels of interference in the system. We formulate this trade off as an optimisation problem with associated constraints, where the cost function is the overall energy consumed in the network and the constraints are the acceptable signal to interference ratio for each node. The solution to this optimisation problem provide optimal values for both the transmission spreading gains and powers that need to be allocated to each node in order to minimise the total energy consumption of the network

Leveraging Deep Learning Based Object Detection for Localising Autonomous Personal Mobility Devices in Sparse Maps

© 2019 IEEE. This paper presents a low cost, resource efficient localisation approach for autonomous driving in GPS denied environments. One of the most challenging aspects of traditional landmark based localisation in the context of autonomous driving, is the necessity to accurately and frequently detect landmarks. We leverage the state of the art deep learning framework, YOLO (You Only Look Once), to carry out this important perceptual task using data obtained from monocular cameras. Extracted bearing only information from the YOLO framework, and vehicle odometry, is fused using an Extended Kalman Filter (EKF) to generate an estimate of the location of the autonomous vehicle, together with it's associated uncertainty. This approach enables us to achieve real-time sub metre localisation accuracy, using only a sparse map of an outdoor urban environment. The broader motivation of this research is to improve the safety and reliability of Personal Mobility Devices (PMDs) through autonomous technology. Thus, all the ideas presented here are demonstrated using an instrumented mobility scooter platform

Educational interventions for imposter phenomenon in healthcare: a scoping review

Background Imposter Phenomenon (IP) is a subjective feeling of intellectual fraudulence and self-doubt experienced by individuals in goal-orientated high-achieving professions. The impact of IP within healthcare has been associated with individual physical and mental health and concerns around training, career progression and DEI at an institutional level. To effectively address IP in healthcare, this scoping review aims to explore educational interventions designed to empower high-achieving individuals with the tools needed to confront and overcome IP. Methods The scoping review adhered to a predetermined protocol informed by the JBI methodology and PRISMA-ScR guidelines in order to identify educational interventions addressing IP in high-achieving industries. Articles were searched across multiple databases, including MEDLINE (Ovid), PsychINFO, SCOPUS, and Web of Science, alongside grey literature, without imposing any time constraints. A systematic approach including a thematic analysis allowed for a nuanced exploration and interpretation of the identified educational interventions and their impact on addressing IP. Results Seventeen articles were incorporated into the review, with the majority originating from the USA and majority being published since 2020. Ten studies targeted healthcare professionals, undergraduate and postgraduate healthcare students. Majority of studies aimed at addressing IP, featured a larger number of female participants than males. Workshops with self-reflection and group-guided exercises to overcome IP were the most popular educational interventions. Coaching and structured supervision were also suggested. Across all papers, three themes emerged for coping strategies: individual, peer-to-peer, and institutional. Conclusions This scoping review suggests how group and individual interventions such as workshops, small group discussions and coaching can be used to overcome IP in healthcare. Institutional changes like diversity promotion, supervisor education, and support networks are crucial in addressing IP. Further long term and speciality specific assessments are needed to measure impact. Overall, the review highlights how educational awareness and a variety of strategies can be implemented to create a supportive environment for professionals dealing with IP, promoting their well-being and success

Measuring mental well-being in Sri Lanka : validation of the Warwick Edinburgh Mental Well-being Scale (WEMWBS) in a Sinhala speaking community

Background: Well-being is an important aspect of people’s lives and can be considered as an index of social progress. The Warwick Edinburgh Mental Well-being scale (WEMWBS) was developed to capture subjective mental well-being. It is a widely tested measure of mental well-being at the population level and has 14 items and a short-form with 7 items. This study was carried out to culturally validate and adapt the WEMWBS among a Sinhala speaking population in Sri Lanka. Methods: A forward and backward translation of the scale into Sinhala was done followed by a cognitive interview. The translated and culturally adapted scale and other mental health scales were administered to a sample of 294 persons between the ages of 17–73 using a paper-based version (n = 210) and an online survey (n = 84). Internal consistency reliability and test–retest reliability were tested. Construct validity, and convergent and discriminant validity were assessed using the total sample. Results: The translated questionnaire had good face and content validity. Internal consistency reliability was 0.91 and 0.84 for the 14-item and 7-item scales, respectively. Test–retest reliability over two weeks was satisfactory (Spearman r = 0.72 p < 0.001). Confirmatory factor analysis supported a one factor model. Convergent validity was assessed using WHO-5 well-being index (Spearman r = 0.67, p < 0.001), Patient Health Questionnaire (PHQ-9) (Spearman r = (-0.45), p < 0.001) and Kessler psychological distress scale (K10) (Spearman r = (-0.55), p < 0.001). Conclusions: The translated and culturally adapted Sinhala version of the WEMWBS has acceptable psychometric properties to assess mental well-being at the population level among the Sinhala speaking population in Sri Lanka
