Implementing electronic data capture at a well-established health and demographic surveillance site in rural northern Malawi.

This article aims to assess multiple issues of resources, staffing, local opinion, data quality, cost, and security while transitioning to electronic data collection (EDC) at a long-running community research site in northern Malawi. Levels of missing and error fields, delay from data collection to availability, and average number of interviews per day were compared between EDC and paper in a complex, repeated annual household survey. Three focus groups with field and data staff with experience using both methods, and in-depth interviews with participants were carried out. Cost for each method were estimated and compared. Missing data was more common on paper questionnaires than on EDC, and a similar number were carried out per day. Fieldworkers generally preferred EDC, but data staff feared for their employment. Most respondents had no strong preference for a method. The cost of the paper system was estimated to be higher than using EDC. The existing infrastructure and technical expertise could be adapted to using EDC, but changes have an impact on data processing jobs as fewer, and better qualified staff are required. EDC is cost-effective, and, for a long-running site, may offer further savings, as devices can be used in multiple studies and perform several other functions. EDC is accepted by fieldworkers and respondents, has good levels of quality and timeliness, and security can be maintained. EDC is well-suited for use in a well-established research site using and developing existing infrastructure and expertise

Minimal information for studies of extracellular vesicles (MISEV2023): From basic to advanced approaches

Extracellular vesicles (EVs), through their complex cargo, can reflect the state of their cell of origin and change the functions and phenotypes of other cells. These features indicate strong biomarker and therapeutic potential and have generated broad interest, as evidenced by the steady year-on-year increase in the numbers of scientific publications about EVs. Important advances have been made in EV metrology and in understanding and applying EV biology. However, hurdles remain to realising the potential of EVs in domains ranging from basic biology to clinical applications due to challenges in EV nomenclature, separation from non-vesicular extracellular particles, characterisation and functional studies. To address the challenges and opportunities in this rapidly evolving field, the International Society for Extracellular Vesicles (ISEV) updates its 'Minimal Information for Studies of Extracellular Vesicles', which was first published in 2014 and then in 2018 as MISEV2014 and MISEV2018, respectively. The goal of the current document, MISEV2023, is to provide researchers with an updated snapshot of available approaches and their advantages and limitations for production, separation and characterisation of EVs from multiple sources, including cell culture, body fluids and solid tissues. In addition to presenting the latest state of the art in basic principles of EV research, this document also covers advanced techniques and approaches that are currently expanding the boundaries of the field. MISEV2023 also includes new sections on EV release and uptake and a brief discussion of in vivo approaches to study EVs. Compiling feedback from ISEV expert task forces and more than 1000 researchers, this document conveys the current state of EV research to facilitate robust scientific discoveries and move the field forward even more rapidly

Teaching senior nurses how to teach communication skills in oncology

Many nurses acknowledge that their nursing practice is hampered by inadequate teaching about communication skills during their nursing education. Ineffective communication has negative effects on patient care and causes stress when nurses interact with each other, with medical colleagues, with patients and their relatives. Many senior nurses teach junior staff about communication and feel uncertain about their competence to do so despite recognition of its importance. This article reports data from a training initiative endorsed by the Royal College of Nursing in the United Kingdom (UK) aimed at helping senior nurses to identify their personal strengths and weaknesses when communicating, learn new teaching methods and encourage new teaching initiatives. A residential 2-day course, based on learner-centered methods was employed. One hundred and twenty nine nurses from UK cancer centers worked on personal communication problems via group discussions, video demonstrations, small group teaching exercises and role-plays with professional actors. Post-course, participants reported significantly greater confidence in handling 14 common communication problem areas in cancer (p < .0001) and in 8 different areas of teaching. Participants were very enthusiastic about the course overall and especially valued the training approach and teaching materials provided. Three months post-course 91% reported changing their own teaching practice and 85% had initiated new communication skills teaching

Teaching senior oncologists communication skills: results from phase I of a comprehensive longitudinal program in the United Kingdom

PURPOSE: To determine the communication difficulties experienced by clinicians in cancer medicine and to develop, implement, and evaluate communication skills training courses. METHODS: One hundred seventy-eight senior clinicians attended 1 1/2- or 3-day residential courses designed to enhance skills development, knowledge acquisition, and personal awareness. Course content included structured feedback, video review of interviews, interactive group demonstrations, and discussion in groups of four led by trained facilitators. The main outcomes were self-rated confidence in key aspects of communication, attitudinal shift toward more patient-centered interviewing, perceived changes in personal practice, and initiation of teaching programs for junior staff. RESULTS: Less than 35% of the participants had received any previous communications training. Time, experience, and seniority had not improved skills; before the course, oncologists expressed difficulty with 998 different communication issues. Primary problems concerned giving complex information, obtaining informed consent, and handling ethnic and cultural differences. Confidence ratings for key communication areas were significantly improved postcourse (P < .01). Three months postcourse, 95% of the physicians reported significant changes in their practice of medicine. Seventy-five percent had started new teaching initiatives in communication for junior clinicians. Clinicians showed positive shifts in attitude toward patients' psychosocial needs (P=.0002) and were more patient centered (P=.03). The courses were highly rated and 97% would "definitely" recommend them to colleagues. CONCLUSION: Oncologists are hampered by inadequate communication skills training and will give up time to correct this. Subjective improvements reported immediately postcourse were maintained at 3 months. Resources for educational initiatives are needed to help both patients and their physicians

Identification of immunological biomarkers which may differentiate latent tuberculosis from exposure to environmental nontuberculous mycobacteria in children.

A positive gamma interferon (IFN-γ) response to Mycobacterium tuberculosis early secretory antigenic target-6 (ESAT-6)/culture filtrate protein-10 (CFP-10) has been taken to indicate latent tuberculosis (TB) infection, but it may also be due to exposure to environmental nontuberculous mycobacteria in which ESAT-6 homologues are present. We assessed the immune responses to M. tuberculosis ESAT-6 and cross-reactive responses to ESAT-6 homologues of Mycobacterium avium and Mycobacterium kansasii. Archived culture supernatant samples from children at 3 years post-BCG vaccination were tested for cytokine/chemokine responses to M. tuberculosis antigens. Furthermore, the IFN-γ responses to M. tuberculosis antigens were followed up for 40 children at 8 years post-BCG vaccination, and 15 TB patients were recruited as a control group for the M. tuberculosis ESAT-6 response in Malawi. IFN-γ enzyme-linked immunosorbent assays (ELISAs) on supernatants from diluted whole-blood assays, IFN-γ enzyme-linked immunosorbent spot (ELISpot) assays, QuantiFERON TB Gold-In Tube tests, and multiplex bead assays were performed. More than 45% of the responders to M. tuberculosis ESAT-6 showed IFN-γ responses to M. avium and M. kansasii ESAT-6. In response to M. tuberculosis ESAT-6/CFP-10, interleukin 5 (IL-5), IL-9, IL-13, and IL-17 differentiated the stronger IFN-γ responders to M. tuberculosis ESAT-6 from those who preferentially responded to M. kansasii and M. avium ESAT-6. A cytokine/chemokine signature of IL-5, IL-9, IL-13, and IL-17 was identified as a putative immunological biosignature to differentiate latent TB infection from exposure to M. avium and M. kansasii in Malawian children, indicating that this signature might be particularly informative in areas where both TB and exposure to environmental nontuberculous mycobacteria are endemic

Towards understanding Sure Start local programmes: Summary of findings from the national evaluation

Sure Start is the Government\u27s programme to support children, families and communities through the integration of early education, childcare, health and family support. Sure Start local programmes are one element of this, based in areas of disadvantage, whose aim is to improve the health and well being of young children under 4 and their families, so that children have a greater opportunity to flourish when they start school. The National Evaluation of Sure Start local programmes has now been in place for 3 years, during which a large amount of information has been collected and reported. This summary draws together some of main published findings from the different strands of the evaluation and in particular highlights some of the newly published findings. These are only a very small selection of findings, intended to provide a flavour and whet the appetite to find out more. At this stage, findings from different parts of the evaluation are reported separately although these will be drawn together more substantially later in the year to assess the overall effect Sure Start local programmes have had on children, parents, families and communities and whether variations in implementation, local community context and costs can explain any differences in effects

Four-Gene Pan-African Blood Signature Predicts Progression to Tuberculosis

Rationale: Contacts of patients with tuberculosis (TB) constitute an important target population for preventive measures because they are at high risk of infection with Mycobacterium tuberculosis and progression to disease.Objectives: We investigated biosignatures with predictive ability for incident TB.Methods: In a case-control study nested within the Grand Challenges 6-74 longitudinal HIV-negative African cohort of exposed household contacts, we employed RNA sequencing, PCR, and the pair ratio algorithm in a training/test set approach. Overall, 79 progressors who developed TB between 3 and 24 months after diagnosis of index case and 328 matched nonprogressors who remained healthy during 24 months of follow-up were investigated.Measurements and Main Results: A four-transcript signature derived from samples in a South African and Gambian training set predicted progression up to two years before onset of disease in blinded test set samples from South Africa, the Gambia, and Ethiopia with little population-associated variability, and it was also validated in an external cohort of South African adolescents with latent M. tuberculosis infection. By contrast, published diagnostic or prognostic TB signatures were predicted in samples from some but not all three countries, indicating site-specific variability. Post hoc meta-analysis identified a single gene pair, C1QC/TRAV27 (complement C1q C-chain / T-cell receptor-α variable gene 27) that would consistently predict TB progression in household contacts from multiple African sites but not in infected adolescents without known recent exposure events.Conclusions: Collectively, we developed a simple whole blood-based PCR test to predict TB in recently exposed household contacts from diverse African populations. This test has potential for implementation in national TB contact investigation programs
