RESUMO

INTRODUCTION: The relative priority received by issues in global health agendas is subjected to impressionistic claims in the absence of objective methods of assessment of priority. To build an approach for conducting structured assessments of comparative priority health issues receive, we expand the public arenas model (2021) and offer a framework for future assessments of health issue priority in global and national health agendas. METHODS: We aimed to develop a more comprehensive set of measures for conducting multiyear priority comparisons of health issues in six agenda-setting arenas by identifying possible measures and data sources, selecting indicators based on feasibility and comparability of measures and gathering the data on selected indicators. We applied these measures to four communicable diseases-tuberculosis (TB), malaria, diarrhoeal diseases and dengue fever-given their differing impressionistic claims of priority. Where possible, we analysed the annual and/or 5-year trends from 2000 through 2022. RESULTS: We observed that TB and malaria received the highest priority for most periods in the past two decades in most arenas. However, a stagnation in development funding for these two conditions over the last 8-10 years may have fuelled the neglect claims. Despite having a higher disease burden, diarrhoea has been slipping in global priority with reduced spending, fewer clinical trials and stagnating publications. Dengue remains a low-priority condition but has witnessed a sharp rise in attention from the pharmaceutical industry. DISCUSSIONS: We expanded the arenas model by including a transnational arena (international representation) and additional measurements for various arenas. This analysis presents an approach to enable comparative trend analysis of the markers of agenda status over a multiyear period. More such analyses can bring much-desired objectivity in understanding how attention to global or national health issues changes over time in different arenas, potentiating a more equitable allocation of resources.

RESUMO

BACKGROUND AND AIMS: Neuropathic-like pain, fatigue, cognitive difficulty, catastrophising, anxiety, sleep disturbance, depression, and widespread pain associate with a single factor in people with knee pain. We report the Central Aspects of Pain questionnaire (CAP) to characterise this across painful musculoskeletal conditions. METHODS: CAP was derived from the 8 item CAP-Knee questionnaire, and completed by participants with joint pain in the Investigating Musculoskeletal Health and Wellbeing survey. Subgroups had osteoarthritis, back pain or fibromyalgia. Acceptability was evaluated by feedback and data missingness. Correlation coefficients informed widespread pain scoring threshold in relation to the other items, and evaluated associations with pain. Factor analysis assessed CAP structure. Intraclass Correlation Coefficient (ICC) between paper and electronic administration assessed reliability. Friedman test assessed score stability over 4 years in people reporting knee osteoarthritis. RESULTS: Data were from 3579 participants (58% female, median age; 71 years), including subgroups with osteoarthritis (n = 1158), back pain (n = 1292) or fibromyalgia (n = 177). Across the 3 subgroups, ≥10/26 painful sites on the manikin scored widespread pain. Reliability was high (ICC= 0.89 (95% CI: 0.84-0.92)) and CAP scores fit to 1 and 2 factor model, with a total CAP score that was associated with pain severity and quality (r = 0.50-0.72). In people with knee pain, CAP scores were stable over 4 years at the group level, but displayed significant temporal heterogeneity within individual participants. CONCLUSIONS: Central Aspects of Pain is reliably measured by the CAP questionnaire across a range of painful musculoskeletal conditions, and is a changeable state.

RESUMO

The highly decentralized nature of global health governance presents significant challenges to conceptualizing and systematically measuring the agenda status of diseases, injuries, risks and other conditions contributing to the collective disease burden. An arenas model for global health agenda setting was recently proposed to help address these challenges. Further developing the model, this study aims to advance more robust inquiry into how and why priority levels may vary among the array of stakeholder arenas in which global health agenda setting occurs. We analyze order and the magnitude of changes in priority for eight infectious diseases in four arenas (international aid, scientific research, pharmaceutical industry and news media) over a period of more than two decades in relation to five propositions from scholarship. The diseases vary on burden and prominence in United Nations Sustainable Development Goal 3 for health and well-being, including four with specific indicators for monitoring and evaluation (HIV/AIDS, tuberculosis, malaria, hepatitis) and four without (dengue, diarrheal diseases, measles, meningitis). The order of priority did not consistently align with the disease burden or international development goals in any arena. Additionally, using new methods to measure the scale of annual change in resource allocations that are indicative of priority reveals volatility at the disease level in all arenas amidst broader patterns of stability. Insights around long-term patterns of priority within and among arenas are integral to strengthening analyses that aim to identify pivotal causal mechanisms, to clarify how arenas interact, and to measure the effects they produce.

RESUMO

The recent review by Eaves et al. (Psychological Research/Psychologische Forschung, 2022) outlines the research conducted to-date on combined action-observation and motor imagery (AOMI), and more specifically, its added benefit to learning. Of interest, these findings have been primarily attributed to the dual action simulation hypothesis, whereby AO and MI activate separable representations for action that may be later merged when they are congruent with one another. The present commentary more closely evaluates this explanation. What's more, we offer an alternative information-based argument where the benefit to learning may be served instead by the availability of key information. Along these lines, we speculate on possible future directions including the need for a transfer design.

RESUMO

BACKGROUND: Knee osteoarthritis is a complex condition with established risk factors such as female sex, increasing age and body mass index, reduced quadriceps muscle strength and knee injury. Despite known associated risks, the role and behaviour of knee tendons in knee osteoarthritis remains unclear. This study explores the association between quadriceps tendon elasticity, muscle strength, neuromuscular control, proprioception and patient reported outcome measures in individuals with knee osteoarthritis. METHODS: Adults with doctor-diagnosed knee osteoarthritis were recruited from rheumatology clinics and general practitioner practices. Quadriceps tendon elasticity was estimated using sonoelastography. Neuromuscular control data including electromyography, electromechanical delay and proprioception measures were included. Participants completed the Knee Injury and Osteoarthritis Outcome Score. Associations between elasticity values, physical and neuromuscular data and patient reported outcomes scores were evaluated using Spearman's correlations. FINDINGS: Thirty-nine adults with knee osteoarthritis were eligible for inclusion. Increased tendon stiffness was negatively associated with rate of force development, time to half peak force and passive positioning sense in individuals with knee osteoarthritis. Similarly, patient reported symptoms were found to be associated with sonoelastography findings with moderate-strong associations observed between activities of daily living sport and recreation, pain and symptoms and between neuromuscular control measures and muscle strength. INTERPRETATION: Stiffer tendon identified within the knee osteoarthritis group was associated with reduced neuromuscular control and knee joint proprioception. Stiffer quadriceps tendon may contribute to the poorer reported symptoms by knee osteoarthritis individuals. These findings may impact disease symptoms and progression which could lead to further joint impairment.

RESUMO

Knee pain is associated with lower muscle strength, and both contribute to disability. Peripheral and central neurological mechanisms contribute to OA pain. Understanding the relative contributions of pain mechanisms to muscle strength might help future treatments. The Knee Pain and related health In the Community (KPIC) cohort provided baseline and year 1 data from people with early knee pain (n = 219) for longitudinal analyses. A cross-sectional analysis was performed with baseline data from people with established knee pain (n = 103) and comparative data from people without knee pain (n = 98). Quadriceps and handgrip strength indicated local and general muscle weakness, respectively. The indices of peripheral nociceptive drive were knee radiographic and ultrasound scores. The indices associated with central pain mechanisms were Pressure Pain detection Threshold (PPT) distal to the knee, and a validated self-report Central Aspects of Pain Factor (CAPF). The associations were explored using correlation and multivariable regression. Weaker quadriceps strength was associated with both high CAPF and low PPT at baseline. Year 1 quadriceps weakness was predicted by higher baseline CAPF (ß = -0.28 (95% CI: -0.55, -0.01), p = 0.040). Weaker baseline and year 1 handgrip strength was also associated with higher baseline CAPF. Weaker baseline quadriceps strength was associated with radiographic scores in bivariate but not adjusted analyses. Quadriceps strength was not significantly associated with total ultrasound scores. Central pain mechanisms might contribute to muscle weakness, both locally and remote from the knee.

RESUMO

The global health agenda-a high stakes process in which problems are defined and compete for the kind of serious attention that promises to help alleviate inequities in the burden of disease-is comprised of priorities set within and among a host of interacting stakeholder arenas. This study informs crucial and unanswered conceptual and measurement questions with respect to civil society priorities in global health. The exploratory two-stage inquiry probes insights from experts based in four world regions and pilots a new measurement approach, analysing nearly 20 000 Tweets straddling the COVID-19 pandemic onset from a set of civil society organizations (CSOs) engaged in global health. Expert informants discerned civil society priorities principally on the basis of observed trends in CSO and social movement action, including advocacy, programme, and monitoring and accountability activities-all of which are widely documented by CSOs active on Twitter. Systematic analysis of a subset of CSO Tweets shows how their attention to COVID-19 soared amidst mostly small shifts in attention to a wide range of other issues between 2019 and 2020, reflecting the impacts of a focusing event and other dynamics. The approach holds promise for advancing measurement of emergent, sustained and evolving civil society priorities in global health.

RESUMO

An advanced ultrasound imaging technique, sonoelastography (SE) is used to evaluate tissue elasticity. To determine SE potential to detect pathological-related changes, and characteristics related to tendon pathology we aimed to (1) compare quadriceps and patellar tendon findings in individuals with knee osteoarthritis (KOA) and asymptomatic older adults (AC), and (2) explore associations between SE, participant characteristics (age, BMI, and leg circumference) and KOA status. 84 participants (47; KOA and 37; asymptomatic older adults) underwent SE examination of quadriceps (distal) and patellar (distal, proximal) tendon in a supine position with the knee bent at 30°. Colour score (CS) and Elasticity Ratio (ER) analysis were performed by a blinded experienced operator using Esaote Mylab 70 XVG Ultrasound equipment. Significantly reduced elasticity in the distal quadriceps (median (IQR) 2(2), 3(1), p = 0.033 for KOA and AC, respectively) and proximal patellar (3(1), 3(0), p = 0.001) tendons and more elastic distal patellar (1.50 (0.55), 1.87 (0.72), p = 0.034) tendons were observed in the KOA group. Significant associations) were identified between SE and participant BMI (Rs = - 0.249-0.750, p < 0.05) and leg circumference (Rs = - 0.260-0.903, p < 0.05). Age, BMI and KOA status, were independent explanatory variables of SE CS findings at the distal quadriceps tendon patellar tendon, proximal patellar tendon and distal patellar tendon, explaining 66%, 81% and 64% of variance, respectively. Age, BMI and KOA status were independent explanatory variables of SE ER findings at the distal patellar tendon explaining 19% of variance. Potentially clinically relevant altered tendon stiffness were observed between individuals with KOA and asymptomatic controls. Key KOA risk factors and participant characteristics explained variance in tendon stiffness. Findings provide context for future studies to investigate the potential for targeted SE detected early clinical management based on associated participant characteristics.

RESUMO

Background: The COVID-19 pandemic caused considerable burden on mental health worldwide. To address this emergency in Peru, Socios en Salud (SES) implemented an innovative digital system for the diagnosis and psychological therapy in vulnerable populations. We describe the development, implementation, and participant outcomes of this intervention. Methods: We conducted an intervention in a general population of Lima, Peru using a digital tool, ChatBot-Juntos, incorporating the abbreviated Self-Reporting Questionnaire (SRQ) to screen psychological distress. Participants positive for psychological distress received remote Psychological First Aid (PFA) and grief therapy if needed. Participants with a mental health condition or safety concern were referred to mental health services. SRQ scores were collected 3 months after PFA sessions. Differences between screening and follow-up scores were compared using Wilcoxon sign-rank test. Results: In total, 2027 people were screened; 1581 (77.9%) screened positive for psychological distress. Nine hundred ninety-seven (63%) people with psychological distress received PFA, and 320 (32.1%) of those were also referred for mental health care. At 3 months after follow-up, SRQ scores were collected for 579 (58%) participants. Significant reduction in SRQ scores was observed 3 months after PFA [median SRQ score changed from 9 to 5 (p < 0.001)], and after PFA plus referral to mental health services [median SRQ score changed from 11 to 6 (p < 0.001)]. Conclusion: Digital technology can be used to screen for psychological distress and deliver mental health support for populations affected by the COVID-19 pandemic. More research is needed to determine whether technology contributes to improved mental health outcomes.

RESUMO

INTRODUCTION: Evidence-based low-intensity psychological interventions such as Problem Management Plus (PM+) have the potential to expand treatment access for depression and anxiety, yet these interventions are not yet effectively implemented in rural, public health systems in resource-limited settings. In 2017, Partners In Health adapted PM+ for delivery by primary care nurses in rural Rwanda and began integrating PM+ into health centres in collaboration with the Rwandan Ministry of Health, using established implementation strategies for mental health integration into primary care (Mentoring and Enhanced Supervision at Health Centers for Mental Health (MESH MH)). A gap in the evidence regarding whether low-intensity psychological interventions can be successfully integrated into real-world primary care settings and improve outcomes for common mental disorders remains. In this study, we will rigorously evaluate the delivery of PM+ by primary care nurses, supported by MESH MH, as it is scaled across one rural district in Rwanda. METHODS AND ANALYSIS: We will conduct a hybrid type 1 effectiveness-implementation study to test the clinical outcomes of routinely delivered PM+ and to describe the implementation of PM+ at health centres. To study the clinical effectiveness of PM+, we will use a pragmatic, randomised multiple baseline design to determine whether participants experience improvement in depression symptoms (measured by the Patient Health Questionnaire-9) and functioning (measured by the WHO-Disability Assessment Scale Brief 2.0) after receiving PM+. We will employ quantitative and qualitative methods to describe and evaluate PM+ implementation outcomes using the Reach, Effectiveness, Adoption, Implementation and Maintenance framework, using routinely collected programme data and semistructured interviews. ETHICS AND DISSEMINATION: This evaluation was approved by the Rwanda National Ethics Committee (Protocol #196/RNEC/2019) and deemed exempt by the Harvard University Institutional Review Board. The results from this evaluation will be useful for health systems planners and policy-makers working to translate the evidence base for low-intensity psychological interventions into practice.

RESUMO

INTRODUCTION: Effective digital health management information systems (HMIS) support health data validity, which enables health care teams to make programmatic decisions and country-level decision making in support of international development targets. In 2015, mental health was included within the Sustainable Development Goals, yet there are few applications of HMIS of any type in the practice of mental health care in resource-limited settings. Zanmi Lasante (ZL), one of the largest providers of mental health care in Haiti, developed a digital data collection system for mental health across 11 public rural health facilities. PROGRAM INTERVENTION: We describe the development, implementation, and evaluation of the digital system for mental health data collection at ZL. To evaluate system reliability, we assessed the number of missing monthly reports. To evaluate data validity, we calculated concordance between the digital system and paper charts at 2 facilities. To evaluate the system's ability to inform decision making, we specified and then calculated 4 priority indicators. RESULTS: The digital system was missing 5 of 143 monthly reports across all facilities and had 74.3% (55/74) and 98% (49/50) concordance with paper charts. It was possible to calculate all 4 indicators, which led to programmatic changes in 2 cases. In response to implementation challenges, it was necessary to use strategies to increase provider buy-in and ultimately to introduce dedicated data clerks to keep pace with data collection and protect time for clinical work. LESSONS LEARNED: While demonstrating the potential of collecting mental health data digitally in a low-resource rural setting, we found that it was necessary to consider the ongoing roles of paper records alongside digital data collection. We also identified the challenge of balancing clinical and data collection responsibilities among a limited staff. Ongoing work is needed to develop truly sustainable and scalable models for mental health data collection in resource-limited settings.

RESUMO

Problem Management Plus (PM+) is a low-intensity psychological intervention developed by the World Health Organization that can be delivered by nonspecialists to address common mental health conditions in people affected by adversity. Emerging evidence demonstrates the efficacy of PM+ across a range of settings. However, the published literature rarely documents the adaptation processes for psychological interventions to context or culture, including curriculum or implementation adaptations. Practical guidance for adapting PM+ to context while maintaining fidelity to core psychological elements is essential for mental health implementers to enable replication and scale. This paper describes the process of contextually adapting PM+ for implementation in Rwanda, Peru, Mexico and Malawi undertaken by the international nongovernmental organization Partners In Health. To our knowledge, this initiative is among the first to adapt PM+ for routine delivery across multiple public sector primary care and community settings in partnership with Ministries of Health. Lessons learned contribute to a broader understanding of effective processes for adapting low-intensity psychological interventions to real-world contexts.

RESUMO

ABSTRACT: Supervision of nonspecialist clinicians by trained mental health professionals is integral to developing capacity for providing mental health care in low-resource settings. Current supervision efforts in low-resource settings, however, are often variable in quality. Scant published literature addresses how supervision practices affect treatment outcomes; only a few studies have been published on evidence-based supervision methods. Additionally, in low-resource settings many systems-level obstacles exist in providing adequate mental health supervision to nonspecialist clinicians. This article seeks to address psychiatrists' role in providing supervision and promoting quality of care in low-resource settings. We review the literature on evidence-based supervision practices, address obstacles and current practices of providing high-quality mental health supervision in low-resource settings, and weave this knowledge with our experiences learning from the clinicians at Partners in Health in Haiti. We also discuss feasible strategies and provide recommendations for strengthening the supervision process in resource-limited settings.

RESUMO

BACKGROUND: There is a growing literature in support of the effectiveness of task-shared mental health interventions in resource-limited settings globally. However, despite evidence that effect sizes are greater in research studies than actual care, the literature is sparse on the impact of such interventions as delivered in routine care. In this paper, we examine the clinical outcomes of routine depression care in a task-shared mental health system established in rural Haiti by the international health care organization Partners In Health, in collaboration with the Haitian Ministry of Health, following the 2010 earthquake. METHODS: For patients seeking depression care betw|een January 2016 and December 2019, we conducted mixed-effects longitudinal regression to quantify the effect of depression visit dose on symptoms, incorporating interaction effects to examine the relationship between baseline severity and dose. RESULTS: 306 patients attended 2052 visits. Each visit was associated with an average reduction of 1.11 in depression score (range 0-39), controlling for sex, age, and days in treatment (95% CI -1.478 to -0.91; p < 0.001). Patients with more severe symptoms experienced greater improvement as a function of visits (p = 0.04). Psychotherapy was provided less frequently and medication more often than expected for patients with moderate symptoms. CONCLUSIONS: Our findings support the potential positive impact of scaling up routine mental health services in low- and middle-income countries, despite greater than expected variability in service provision, as well as the importance of understanding potential barriers and facilitators to care as they occur in resource-limited settings.

RESUMO

BACKGROUND: The global health agenda is ill-defined as an analytical construct, complicating attempts by scholars and proponents to make claims about the agenda status of issues. We draw on Kingdon's definition of the agenda and Hilgartner and Bosk's public arenas model to conceptualize the global health agenda as those subjects or problems to which collectivities of actors operating nationally and globally are paying serious attention at any given time. We propose an arenas model for global health agenda setting and illustrate its potential utility by assessing priority indicators in five arenas, including international aid, pharmaceutical industry, scientific research, news media and civil society. We then apply the model to illustrate how the status of established (HIV/AIDS), emergent (diabetes) and rising (Alzheimer's disease) issues might be measured, compared and change in light of a pandemic shock (COVID-19). RESULTS: Coronavirus priority indicators rose precipitously in all five arenas in 2020, reflecting the kind of punctuation often caused by focusing events. The magnitude of change varied somewhat by arena, with the most pronounced shift in the global news media arena. Priority indicators for the other issues showed decreases of up to 21% and increases of up to 41% between 2019 and 2020, with increases suggesting that the agenda for global health issues expanded in some arenas in 2020- COVID-19 did not consistently displace priority for HIV/AIDS, diabetes or Alzheimer's disease, though it might have for other issues. CONCLUSIONS: We advance an arenas model as a novel means of addressing conceptual and measurement challenges that often undermine the validity of claims concerning the global health agenda status of problems and contributing causal factors. Our presentation of the model and illustrative analysis lays the groundwork for more systematic investigation of trends in global health agenda setting. Further specification of the model is needed to ensure accurate representation of vital national and transnational arenas and their interactions, applicability to a range of disease-specific, health systems, governance and policy issues, and sensitivity to subtler influences on global health agenda setting than pandemic shocks.

RESUMO

Closely related species that have previously inhabited geographically separated ranges are hybridizing at an increasing rate due to human disruptions. These human-mediated hybrid zones can be used to study reproductive isolation between species at secondary contact, including examining locus-specific rates of introgression. Introgression is expected to be heterogenous across the genome, reflecting variation in selection. Those loci that introgress especially slowly are good candidates for being involved in reproductive isolation, while those loci that introgress quickly may be involved in adaptive introgression. In the context of conservation, policy makers are especially concerned about introduced alleles moving quickly into the background of a native or endemic species, as these alleles could replace the native alleles in the population, leading to extinction via hybridization. We applied genomic cline analyses to 44,997 SNPs to identify loci introgressing more or less when compared to the genome wide expectation in a human-mediated hybridizing population of red deer and sika in Kintyre Scotland. We found 11.4% of SNPs had cline centres that were significantly different from the genome wide expectation, and 17.6% of all SNPs had excess rates of introgression. Based on simulations, we believe that many of these markers have diverged from the genome-wide average due to drift, rather than because of selection, and we suggest that these simulations can be useful as a null distribution for future studies of genomic clines. Future work on red deer and sika could determine the policy implications of allelic-replacement due to drift rather than selection, and could use replicate, geographically distinct hybrid zones to narrow down those loci that are responding to selection.

RESUMO

OBJECTIVES: To explore the associations between participant characteristics and magnitudes of difference in paired elastography measures of knee tendon from different ultrasound systems, and to compare strain elastography pattern description. MATERIALS AND METHODS: Quadriceps and patellar tendons of 20 healthy volunteers (40 tendons) were examined by an experienced operator employing two ultrasound systems (GE S8 and Esaote MyLab 70XVG). Pearson/Spearman correlations explored the influence of participant characteristics (BMI, body fat %, leg circumference, activity level) on the magnitude of differences between measures. Paired-sample t test or Wilcoxon signed rank test were performed to compare repeated measures of individual ultrasound systems. RESULTS: The quadriceps tendon was characteristically stiffer than the patellar tendon. Participant characteristics were associated with within machine differences of the distal quadriceps tendon (BMI; r = 0.49, p = 0.028-0.03 and body fat %; r = 0.43, p = 0.05-0.056) ER measures. CONCLUSIONS: Anthropometric and body composition parameters were associated with within machine differences for elasticity measures, where high BMI and body fat % contribute to paired measurement variance at the distal quadriceps tendon. Strain elastography protocols should be standardised, repeated ER measures performed using the same US system and patient characteristics considered for future clinical applications.

RESUMO

BACKGROUND: Integrating epilepsy care into primary care settings could reduce the global burden of illness attributable to epilepsy. Since 2012, the Rwandan Ministry of Health and the international nonprofit Partners In Health have collaboratively used a multi-faceted implementation program- MESH MH-to integrate and scale-up care for epilepsy and mental disorders within rural primary care settings in Burera district, Rwanda. We here describe demographics, service use and treatment patterns for patients with epilepsy seeking care at MESH-MH supported primary care health centers. METHODS AND FINDINGS: This was a retrospective cohort study using routinely collected data from fifteen health centers in Burera district, from January 2015 to December 2016. 286 patients with epilepsy completed 3307 visits at MESH-MH participating health centers over a two year period (Jan 1st 2015 to Dec 31st 2016). Men were over twice as likely to be diagnosed with epilepsy than women (OR 2.38, CI [1.77-3.19]), and children under 10 were thirteen times as likely to be diagnosed with epilepsy as those 10 and older (OR 13.27, CI [7.18-24.51]). Carbamazepine monotherapy was prescribed most frequently (34% of patients). CONCLUSION: Task-sharing of epilepsy care to primary care via implementation programs such as MESH-MH has the potential to reduce the global burden of illness attributable to epilepsy.

RESUMO

Many claims are made concerning which issues are on the global health agenda and which are neglected. Scholarship is inconsistent and generally vague about how an issue's status is (or should be) measured, however, leaving such claims open to questions about their validity. This inquiry explores a novel way of addressing the largely overlooked matter of how to comparatively assess the agenda status of health issues systematically, over time and in consideration of a global health context that lacks centralised authority. We draw upon a model from sociology which proposes that collective definitions of social problems and public attention evolve in multiple, interacting institutional arenas, each of which has the capacity to give robust attention to a limited number of issues. We systematically track status indicators for two significant global health issues, diabetes and oral diseases, in three arenas since 2000. Oral health's status declined while diabetes rose in international representation, international organisation and scientific research arenas during the past decade. This article sets out some preliminary contours of an analytical approach that holds promise for enhancing understanding of causal mechanisms and outcomes across a wider set of global health issues and agenda setting arenas.
