Handling sensitive topics ​in partnership with young people: Reflections on collaboration within a configurative systematic review​

We present reflections on work with a group of young people during a qualitative evidence synthesis about eating disorder related content that can be accessed online. Our aim was to help young peoples’ priorities and concerns be better reflected in the review, so as to better inform the development of policies that affect them. A review team and a small group of young people with experience of this content worked together during the review. Interactive online workshops and other activities helped to refine the review’s focus from an early stage, identified gaps in understanding, informed reviewers’ analyses and affected communication of the review and its findings. Approaches designed to address ethical issues around handling sensitive topics in research were adapted for use in the review and involvement activities. As well as taking steps to promote participation rights for young people, given a pandemic context, the review team made efforts to communicate their own concerns, for example about unanticipated delays. Evaluation findings so far suggest that aiming for a culture of mutual respect can help ensure continued interest for all and support the production of a more impactful systematic review

Running-Related Biomechanical Risk Factors for Overuse Injuries in Distance Runners: A Systematic Review Considering Injury Specificity and the Potentials for Future Research

Background: Running overuse injuries (ROIs) occur within a complex, partly injury-specific interplay between training loads and extrinsic and intrinsic risk factors. Biomechanical risk factors (BRFs) are related to the individual running style. While BRFs have been reviewed regarding general ROI risk, no systematic review has addressed BRFs for specific ROIs using a standardized methodology. Objective: To identify and evaluate the evidence for the most relevant BRFs for ROIs determined during running and to suggest future research directions. Design: Systematic review considering prospective and retrospective studies. (PROSPERO_ID: 236,832). Data Sources: PubMed. Connected Papers. The search was performed in February 2021. Eligibility Criteria: English language. Studies on participants whose primary sport is running addressing the risk for the seven most common ROIs and at least one kinematic, kinetic (including pressure measurements), or electromyographic BRF. A BRF needed to be identified in at least one prospective or two independent retrospective studies. BRFs needed to be determined during running. Results: Sixty-six articles fulfilled our eligibility criteria. Levels of evidence for specific ROIs ranged from conflicting to moderate evidence. Running populations and methods applied varied considerably between studies. While some BRFs appeared for several ROIs, most BRFs were specific for a particular ROI. Most BRFs derived from lower-extremity joint kinematics and kinetics were located in the frontal and transverse planes of motion. Further, plantar pressure, vertical ground reaction force loading rate and free moment-related parameters were identified as kinetic BRFs. Conclusion: This study offers a comprehensive overview of BRFs for the most common ROIs, which might serve as a starting point to develop ROI-specific risk profiles of individual runners. We identified limited evidence for most ROI-specific risk factors, highlighting the need for performing further high-quality studies in the future. However, consensus on data collection standards (including the quantification of workload and stress tolerance variables and the reporting of injuries) is warranted

Hes1 Is Expressed in the Second Heart Field and Is Required for Outflow Tract Development

Background: Rapid growth of the embryonic heart occurs by addition of progenitor cells of the second heart field to the poles of the elongating heart tube. Failure or perturbation of this process leads to congenital heart defects. In order to provide further insight into second heart field development we characterized the insertion site of a transgene expressed in the second heart field and outflow tract as the result of an integration site position effect. Results: Here we show that the integration site of the A17-Myf5-nlacZ-T55 transgene lies upstream of Hes1, encoding a basic helix-loop-helix containing transcriptional repressor required for the maintenance of diverse progenitor cell populations during embryonic development. Transgene expression in a subset of Hes1 expression sites, including the CNS, pharyngeal epithelia, pericardium, limb bud and lung endoderm suggests that Hes1 is the endogenous target of regulatory elements trapped by the transgene. Hes1 is expressed in pharyngeal endoderm and mesoderm including the second heart field. Analysis of Hes1 mutant hearts at embryonic day 15.5 reveals outflow tract alignment defects including ventricular septal defects and overriding aorta. At earlier developmental stages, Hes1 mutant embryos display defects in second heart field proliferation, a reduction in cardiac neural crest cells and failure to completely extend the outflow tract. Conclusions: Hes1 is expressed in cardiac progenitor cells in the early embryo and is required for development of the arteria

Pregnancy cohorts and biobanking in sub-Saharan Africa: a systematic review

Background: Technological advances and high throughput biological assays can facilitate discovery science in biobanks from population cohorts, including pregnant women. Biological pathways associated with health outcomes differ depending on geography, and high-income country data may not generalise to low-resource settings. We conducted a systematic review to identify prospective pregnancy cohorts in sub-Saharan Africa (SSA) that include biobanked samples with potential to enhance discovery science opportunity. Methods: Inclusion criteria were prospective data collection during pregnancy, with associated biobanking in SSA. Data sources included: scientific databases (with comprehensive search terms), grey literature, hand searching applicable reference lists and expert input. Results were screened in a three-stage process based on title, abstract and full text by two independent reviewers. The review is registered on PROSPERO (CRD42019147483). Results: Fourteen SSA studies met the inclusion criteria from database searches (n=8), reference list searches (n=2) and expert input (n=4). Three studies have ongoing data collection. The most represented countries were South Africa and Mozambique (Southern Africa) (n=3), Benin (Western Africa) (n=4) and Tanzania (Eastern Africa) (n=4); including an estimated 31 763 women. Samples commonly collected were blood, cord blood and placenta. Seven studies collected neonatal samples. Common clinical outcomes included maternal and perinatal mortality, malaria and preterm birth. Conclusions: Increasingly numerous pregnancy cohorts in SSA that include biobanking are generating a uniquely valuable resource for collaborative discovery science, and improved understanding of the high regional risks of maternal, fetal and neonatal morbidity and mortality. Future studies should align protocols and consider their added value and distinct contributions

Age-related changes in prefrontal and hippocampal contributions to relational encoding

Age-related declines in relational encoding are well documented. It remains unclear, however, whether such declines reflect dysfunction of (1) ventrolateral prefrontal cortex (VLPFC) and deficient generation of associations; and/or (2) hippocampal dysfunction and impoverished binding of associations. In order to separate VLPFC and hippocampal contributions to relational encoding, we manipulated the generative demands of the encoding task by varying the number of semantic associations between the to-be-encoded information (three words). Thus, trials with fewer semantic associations (lower-association trials) require more generative processing during encoding, relative to trials in which more semantic associations are provided for binding (higher-association trials). Parametric modulation analyses on successfully encoded items revealed that, unlike younger adults, older adults did not show an up-regulation of VLPFC activity during lower-association trials. In contrast, hippocampal activity in both older and younger adults was greater in higher- relative to lower-association trials. Moreover, recognition accuracy improved significantly in both groups with the provision of more semantic associations, indicating the both younger and older adults benefitted from this form of encoding support. Our findings suggest that left VLPFC dysfunction may underlie relational encoding deficits in older adults, but that when provided with associations to bind, hippocampal activity in older adults is comparable to young, consistent with their increased recognition accuracy under conditions of encoding support

Identifying Areas with Disproportionate Local Health Department Services Relative to Opioid Overdose, HIV and Hepatitis C Diagnosis Rates: A Study of Rural Illinois

Background: U.S. rural populations have been disproportionately affected by the syndemic of opioid-use disorder (OUD) and the associated increase in overdoses and risk of hepatitis C virus (HCV) and human immunodeficiency virus (HIV) transmission. Local health departments (LHDs) can play a critical role in the response to this syndemic. We utilized two geospatial approaches to identify areas of discordance between LHD service availability and disease burden to inform service prioritization in rural settings.Methods: We surveyed rural Illinois LHDs to assess their OUD-related services, and calculated county-level opioid overdose, HIV, and hepatitis C diagnosis rates. Bivariate choropleth maps were created to display LHD service provision relative to disease burden in rural Illinois counties. Results: Most rural LHDs provided limited OUD-related services, although many LHDs provided HIV and HCV testing. Bivariate mapping showed rural counties with limited OUD treatment and HIV services and with corresponding higher outcome/disease rates to be dispersed throughout Illinois. Additionally, rural counties with limited LHD-offered hepatitis C services and high hepatitis C diagnosis rates were geographically concentrated in southern Illinois. Conclusions: Bivariate mapping can enable geographic targeting of resources to address the opioid crisis and related infectious disease by identifying areas with low LHD services relative to high disease burden

“Like works of our hands are giving testimony!” A qualitative study on kangaroo mother care and health worker empowerment in southern Malawi

The purpose of this paper is to explore health worker perspectives of empowerment associated with kangaroo mother care in southern Malawi. We conducted a secondary analysis of 27 in-depth interviews collected between May-Aug 2019 at a large Malawian tertiary hospital and three rural referral hospitals. Data was analyzed using a thematic approach with NVivo 12 software (QSR International, Melbourne, Australia). Health workers reported positive perceptions of kangaroo mother care because it helped save the lives of preterm and low birthweight infants who previously did not frequently survive. This gave them hope due to increased capacity to care for low birthweight infants and subsequently increased job satisfaction. Experiences of success supported workplace morale and strengthened commitment to their clinical roles. This study suggests that kangaroo mother care may support health worker empowerment and resilience in their work.   Cet article-ci se prend pour son objectif d'explorer les perspectives de l'autonomie associée avec les soins maternels kangourous implémentés aux cliniques médicales dans le sud du Malawi. Les perspectives de l'autonomie dont on parle ici appartiennent aux travailleurs de la santé. Nous avons effectué une analyse secondaire de vingt-sept entrevues collectionnées entre les mois mai et août en 2019 au Malawi à une hôpital de soins tertiaires et aux trois hôpitaux d'aiguillage ruraux. Les données ont été analysées en utilisant l'approche thématique avec le logiciel NVivo 12 (QSR International, Melbourne, Australia). Les travailleurs de la santé ont communiqué les perceptions positives des soins maternels kangourous parce que ceux-ci les ont aidé à sauver les vies des nourrissons prématurés et de faible poids de naissance qui autrefois souvent n'avaient pas survécu. Ceci leur a donné de l'espoir parce que leur capacité de prendre soin des nourrissons de faible poids de naissance est accrue et ensuite leur satisfaction au travail a augmenté aussi. Ces expériences de succès ont soutenu leur morale au travail et ont renforcé leur engagement envers leur rôles cliniques. Cette étude-ci suggère que les soins maternels kangourou peuvent promouvoir l'autonomie des travailleurs de la santé et leur résilience dans leur travail. &nbsp
