Does epidemiological evidence support the success story of Uganda's response to COVID-19?

Uganda has received praise for its success in dealing with the COVID-19 pandemic. This opinion piece uses publically available data from Johns Hopkins University to suggest that it is far from clear whether the Public Health and Social Measures (PHSM) introduced in Uganda influenced the course of the first outbreak. In addition, the analysis of data from the second and third waves in Uganda suggest that government action had little or no effect on these outbreaks. The dominant narrative of successful PHSM, therefore, needs to be reconsidered, and alternative explanations for the low rates of COVID-19-related mortality in the country need to be further understood.

Healthcare use attributable to COVID-19: a propensity-matched national electronic health records cohort study of 249,390 people in Wales, UK

BACKGROUND

To determine the extent and nature of changes associated with COVID-19 infection in terms of healthcare utilisation, this study observed healthcare contact 1 to 4 and 5 to 24 weeks following a COVID-19 diagnosis compared to propensity-matched controls.

METHODS

Two hundred forty nine thousand three hundred ninety Welsh individuals with a positive reverse transcription-polymerase chain reaction (RT-PCR) test were identified from data from national PCR test results. After elimination criteria, 98,600 positive individuals were matched to test negative and never tested controls using propensity matching. Cohorts were split on test location. Tests could be taken in either the hospital or community. Controls were those who had tested negative in their respective environments. Survival analysis was utilised for first clinical outcomes which are grouped into primary and secondary. Primary outcomes include post-viral-illness and fatigue as an indication of long-COVID. Secondary outcomes include clinical terminology concepts for embolism, respiratory conditions, mental health conditions, fit notes, or hospital attendance. Increased instantaneous risk for positive individuals was quantified using hazard ratios (HR) from Cox regression, while absolute risk (AR) and relative risk were quantified using life table analysis.

RESULTS

Analysis was conducted using all individuals and stratified by test location. Cases are compared to controls from the same test location. Fatigue (HR: 1.77, 95% CI: 1.34-2.25, p =  < 0.001) and embolism (HR: 1.50, 95% CI: 1.15-1.97, p = 0.003) were more likely to occur in all positive individuals in the first 4 weeks; however, anxiety and depression (HR: 0.83, 95% CI: 0.73-0.95, p = 0.007) were less likely. Positive individuals continued to be more at risk of fatigue (HR: 1.47, 95% CI: 1.24-1.75, p =  < 0.001) and embolism (HR: 1.51, 95% CI: 1.13-2.02, p = 0.005) after 4 weeks. All positive individuals are also at greater risk of post-viral illness (HR: 4.57, 95% CI: 1.77-11.80, p = 0.002). Despite statistical association between testing positive and several conditions, life table analysis shows that only a small minority of the study population were affected.

CONCLUSIONS

Community COVID-19 disease is associated with increased risks of post-viral-illness, fatigue, embolism, and respiratory conditions. Despite elevated risks, the absolute healthcare burden is low. Subsequently, either very small proportions of people experience adverse outcomes following COVID-19 or they are not presenting to healthcare.

Differential expression of C5aR1 and C5aR2 in innate and adaptive immune cells located in early skin lesions of bullous pemphigoid patients

Bullous pemphigoid (BP), the by far most frequent autoimmune subepidermal blistering disorder (AIBD), is characterized by the deposition of autoantibodies against BP180 (type XVII collagen; Col17) and BP230 as well as complement components at the dermal-epidermal junction (DEJ). The mechanisms of complement activation in BP patients, including the generation of C5a and regulation of its two cognate C5aRs, i.e., C5aR1 and C5aR2, are incompletely understood. In this study, transcriptome analysis of perilesional and non-lesional skin biopsies of BP patients compared to site-, age-, and sex-matched controls showed an upregulated expression of C5AR1, C5AR2, CR1, and C3AR1 and other complement-associated genes in perilesional BP skin. Of note, increased expressions of C5AR2 and C3AR1 were also observed in non-lesional BP skin. Subsequently, double immunofluorescence (IF) staining revealed T cells and macrophages as the dominant cellular sources of C5aR1 in early lesions of BP patients, while C5aR2 mainly expressed on mast cells and eosinophils. In addition, systemic levels of various complement factors and associated molecules were measured in BP patients and controls. Significantly higher plasma levels of C3a, CD55, and mannose-binding lectin-pathway activity were found in BP patients compared to controls. Finally, the functional relevance of C5aR1 and C5aR2 in BP was explored by two in vitro assays. Specific inhibition of C5aR1, resulted in significantly reduced migration of human neutrophils toward the chemoattractant C5a, whereas stimulation of C5aR2 showed no effect. In contrast, the selective targeting of C5aR1 and/or C5aR2 had no effect on the release of reactive oxygen species (ROS) from Col17-anti-Col17 IgG immune complex-stimulated human leukocytes. Collectively, this study delineates a complex landscape of activated complement receptors, complement factors, and related molecules in early BP skin lesions. Our results corroborate findings in mouse models of pemphigoid diseases that the C5a/C5aR1 axis is pivotal for attracting inflammatory cells to the skin and substantiate our understanding of the C5a/C5aR1 axis in human BP. The broad expression of C5aRs on multiple cell types critical for BP pathogenesis call for clinical studies targeting this axis in BP and other complement-mediated AIBDs.

Emergency pacemaker implantation in nonagenarians with complete heart block: is single chamber pacing sufficient?

Background

In ambulatory patients with complete heart block and preserved sinus node activity (CHBs), dual chamber pacing confers well-established physiological benefits versus single chamber pacing. There is limited evidence as to whether these benefits extend to very frail patients, especially those over 90 years of age.

Purpose

In nonagenarians presenting with emergent CHBs from 2016–2019, we compared the clinical characteristics of patients selected for single versus dual chamber pacemakers (PPM), and evaluated the symptomatic and prognostic implications of these devices.

Methods

Baseline characteristics were discerned from electronic records, and physiological data extracted from serial PPM interrogations. Frailty was quantified according to the Rockwood clinical frailty scale (1–9). Cause of death was provided by the patients' General Practitioner. Cox proportional hazards analysis (HR, 95% CI) examined associations with all-cause mortality and death from congestive cardiac failure (CCF).

Results

168 consecutive patients were included (44.3% Male, Median age: 91 (2) years) and followed-up for 26.9±14.6 months. 22 patients (13.1%) were implanted with single chamber pacemakers (all programmed VVIR); when compared with patients receiving dual chamber devices, these patients had similar median age (93 (3) versus 91 (2) years, p=0.15) and LV systolic function (LVEF: 49.2% ±9.7 versus 50.7% ±10.1, p=0.71), but were more frail (Rockwood scale: 5.2±1.8 versus 4.3±1.1, p=0.004) and more likely to have severe cognitive impairment (27.3% versus 9.2%, p=0.018). Post implant, patients who received single chamber devices had higher average respiratory rates (21.3±2.4 breaths per minute versus 17.5±2.6 breaths per minute, p=0.002), lower average heart rates (65.5±10.1 bpm versus 71.9±8.6 bpm, p=0.002), and lower daily activity levels (0.57±0.3 hours of activity versus 1.5±1.1 hours of activity, p=0.016) than those with dual chamber devices. Death from CCF was more common in patients receiving single chamber devices (40.9% versus 6.2%, log rank p&lt;0.0001); this association persisted when adjusting for age, frailty and cognitive impairment (adjusted HR: 6.2 (2.2–17.3, p=0.0005). However, in this age group, single chamber pacing was not independently associated with all-cause mortality when compared with dual chamber pacing (adjusted HR: 1.9 (0.95–3.6, p=0.07).

Conclusions

In nonagenarians with CHBs, dual chamber pacing was associated with improved symptomatic outcomes and a reduced risk of death from CCF, but did not affect all-cause mortality when compared with single chamber pacing.

Cutaneous kinase activity correlates with treatment outcomes following PI3K delta inhibition in mice with experimental pemphigoid diseases

Chronic blistering at the skin and/or mucous membranes, accompanied by a varying degree of inflammation, is the clinical hallmark of pemphigoid diseases that impose a major medical burden. Pemphigoid diseases are caused by autoantibodies targeting structural proteins of the epithelial basement membrane. One major pathogenic pathway of skin blistering and inflammation is activation of myeloid cells following Fc gamma receptor-dependent binding to the skin-bound immune complexes. This process requires activation of specific kinases, such as PI3Kδ, which have emerged as potential targets for the treatment of pemphigoid diseases. Yet, it is unknown if global cutaneous kinase activity present in lesional pemphigoid disease correlates with therapeutic effects following treatment with a given target-selective kinase inhibitor. To address this, we here first determined the kinase activity in three different mouse models of pemphigoid diseases: Antibody transfer-induced mucous membrane pemphigoid (MMP), antibody transfer-induced epidermolysis bullosa acquisita (EBA) and immunization-induced EBA. Interestingly, the kinome signatures were different among the three models. More specifically, PI3Kδ was within the kinome activation network of antibody transfer-induced MMP and immunization-induced EBA, but not in antibody transfer-induced EBA. Next, the therapeutic impact of the PI3Kδ-selective inhibitor parsaclisib was evaluated in the three model systems. In line with the kinome signatures, parsaclisib had therapeutic effects in antibody transfer-induced MMP and immunization-induced EBA, but not in autoantibody-induced EBA. In conclusion, kinase activation signatures of inflamed skin, herein exemplified by pemphigoid diseases, correlate with the therapeutic outcomes following kinase inhibition, demonstrated here by the PI3Kδ inhibitor parsaclisib.

1051 EMERGENCY PACEMAKER IMPLANTATION IN NONAGENARIANS: IMPACT OF FRAILTY ON OPERATOR DECISION-MAKING AND PATIENT OUTCOMES

Introduction

Complete heart block (CHB) is a time-critical emergency. In frail patients with CHB, the absence of test results or a comprehensive history can challenge operator decision-making; in particular, minimal data exists as to the prognostic impact of single versus dual chamber pacing in this group. In patients over 90 years of age presenting with CHB, we examined the prognostic value of parameters obtained from bedside examination, and analysed the impact of single versus dual chamber pacemakers on mortality.

Method

Data were extracted from 2016–2019. Bedside covariates were age, sex, previous cardiac surgery, atrial rhythm, LV systolic function, syncope at presentation, QRS duration, and Rockwood frailty score. Cox-proportional hazards regression examined associations with all-cause mortality and cardiac death, determined from electronic records and death certificates (adjusted HR, 95% CI).

Results

205 patients were included (age 92.3 ± 2.3 years, 45.4% male). Mortality was 13.8% at 90 days and 27.2% at 27.1 ± 16.7 months. The independent predictors of mortality were pre-procedural QRS duration &gt;130 ms (HR 2.4 (1.4–4.1) p = 0.001), age (HR 1.07 (1.02–1.15) p = 0.004), AF (HR 2.0 (1.1–3.6) p = 0.02), and Rockwood score (HR 1.2 (1.02–2.6), p = 0.043). Sex, syncope at presentation, LV function or previous cardiac surgery did not predict mortality (all p &gt; 0.1). In a subset of 168 patients without AF, 30 (17.8%) received single chamber pacemakers. Whilst these patients were more frail than those receiving dual chamber pacemakers (Rockwood scores: 5.2 ± 1.7 vs 4.3 ± 1.1, p = 0.025), implantation of a single chamber pacemaker was independently associated with cardiac death when adjusting for frailty and co-morbidities (HR 6 (1.4–26.4), p = 0.018).

Conclusion

Nonagenarians undergoing emergency pacemaker implantation have a reasonable prognosis. Data ascertained at the bedside can help predict survival, however—when adjusting for frailty and co-morbidities—dual chamber pacing may confer an independent mortality benefit over single chamber pacing in this group.

Electroconvulsive Therapy’s use in Idiopathic Intracranial Hypertension with Mood Disorder: caution, promise, and progress

Introduction

Idiopathic Intracranial Hypertension (IIH) is a condition characterized by an increase of intracranial pressure (ICP) with no identifiable cause to date. One-half of patients who suffer from IIH have co-morbid mood disorders, such as Major Depressive Disorder (MDD), that can be refractory to pharmacologic treatment. Electroconvulsive Therapy (ECT) is a safe and effective treatment for treatment-refractory mood disorder, but possesses a relative contra-indication for IIH due to its theoretical increase in ICP. Can ECT become the gold-standard treatment modality for mood disorder from IIH?

Objectives

We aim to synthesize and summarize the state of the literature surrounding the intersection of ECT and IIH. We will present notable findings and propose avenues for future investigation.

Methods

We conducted a literature review using PubMed’s search function. Key terms that were queried are as follows: Idiopathic Intracranial Hypertension, Pseudotumor Cerebri, Benign Intracranial Hypertension, Mood Disorder, Major Depressive Disorder, ECT, Electroconvulsive Therapy.

Results

The prevailing theory of IIH and mood disorder centers around HPA axis dysfunction, which has been heavily theorized to be positively impacted with ECT. ECT itself may not increase the ICP, but the anesthesia might. The only two case reports in the literature presented safe and successful use of ECT’s in patients with IIH and MDD.

Conclusions

More data is needed to draw conclusions, as the literature surrounding ECT’s use in patients with IIH remains sparse. Further studies must explore whether ECT’s use in IIH remains effective. Through this, we may understand more about both IIH and ECT itself.

The modifying enzyme Tsr3 establishes the hierarchy of Rio kinase binding in 40S ribosome assembly

Ribosome assembly is an intricate process, which in eukaryotes is promoted by a large machinery comprised of over 200 assembly factors (AFs) that enable the modification, folding, and processing of the ribosomal RNA (rRNA) and the binding of the 79 ribosomal proteins. While some early assembly steps occur via parallel pathways, the process overall is highly hierarchical, which allows for the integration of maturation steps with quality control processes that ensure only fully and correctly assembled subunits are released into the translating pool. How exactly this hierarchy is established, in particular given that there are many instances of RNA substrate "handover" from one highly related AF to another, remains to be determined. Here we have investigated the role of Tsr3, which installs a universally conserved modification in the P-site of the small ribosomal subunit late in assembly. Our data demonstrate that Tsr3 separates the binding of the Rio kinases, Rio2 and Rio1, with whom it shares a binding site. By binding after Rio2 dissociation, Tsr3 prevents rebinding of Rio2, promoting forward assembly. After rRNA modification is complete, Tsr3 dissociates, thereby allowing for recruitment of Rio1 into its functional site. Inactive Tsr3 blocks Rio1 function, which can be rescued using mutants that bypass the requirement for Rio1 activity. Finally, yeast strains lacking Tsr3 randomize the binding of the two kinases, leading to the release of immature ribosomes into the translating pool. These data demonstrate a role for Tsr3 and its modification activity in establishing a hierarchy for the function of the Rio kinases.

Vaccine anxieties, vaccine preparedness: Perspectives from Africa in a Covid-19 era

Global debates about vaccines as a key element of pandemic response and future preparedness in the era of Covid-19 currently focus on questions of supply, with attention to global injustice in vaccine distribution and African countries as rightful beneficiaries of international de-regulation and financing initiatives such as COVAX. At the same time, vaccine demand and uptake are seen to be threatened by hesitancy, often attributed to an increasingly globalised anti-vaxx movement and its propagation of misinformation and conspiracy, now reaching African populations through a social media 'infodemic'. Underplayed in these debates are the socio-political contexts through which vaccine technologies enter and are interpreted within African settings, and the crucial intersections between supply and demand. We explore these through a 'vaccine anxieties' framework attending to both desires for and worries about vaccines, as shaped by bodily, societal and wider political understandings and experiences. This provides an analytical lens to organise and interpret ethnographic and narrative accounts in local and national settings in Uganda and Sierra Leone, and their (dis)connections with global debates and geopolitics. In considering the socially-embedded reasons why people want or do not want Covid-19 vaccines, and how this intersects with the dynamics of vaccine supply, access and distribution in rapidly-unfolding epidemic situations, we bring new, expanded insights into debates about vaccine confidence and vaccine preparedness.

Communicating Endometriosis Pain in France and Australia: An Interview Study

Endometriosis is characterized by persistent, fluctuating pain associated with menstruation, a biological function which is socially invisible. The degree and quality of pain cannot easily be measured, observed, or documented. Difficulties in communicating pain pose particular challenges when seeking diagnosis and support from health professionals. In this paper we explore the experiences and characterization of pain by thirteen Australian and thirteen French women with endometriosis. Data were collected through semi-structured interviews using a life-history approach to illness symptoms, diagnosis and treatment. We explore the experiences of women with endometriosis in two phases: from onset of symptoms to seeking advice from a clinician, and from first consulting a clinician to receiving a diagnosis. On average, initial pain symptoms were identified 2.1 years before consulting a health practitioner, after which women reported pain symptoms 8.5 years prior to diagnosis; that is, the time between consulting a clinician and receiving a diagnosis was almost four times the period between experiencing symptoms and consulting a doctor. Pain was often “made real” to doctors by findings consistent with endometriosis on ultrasound and MRI, mostly used in France, or laparoscopy, the predominant diagnostic tool in Australia. No woman described her practitioner using standardized pain assessment tools. Thus, the validation of pain relies largely on disease visibility and the clinician-classified degree of severity rather than self-reported grades of pain or impact on activities of daily living. The invisible and enigmatic pain of this chronic women's disease remains difficult to communicate to doctors, and the recognition of severe pain is often key to timely diagnostic procedures. Clinicians need to be more proactive about severe pain related to menstruation, taking into consideration women's individual circumstances, and maintain a high index of suspicion of underlying endometriosis as a condition characterized primarily by pain.

Balanced Versus Unbalanced Fluid in Critically Ill Children: Systematic Review and Meta-Analysis

OBJECTIVES

The ideal crystalloid fluid bolus therapy for fluid resuscitation in children remains unclear, but pediatric data are limited. Administration of 0.9% saline has been associated with hyperchloremic metabolic acidosis and acute kidney injury. The primary objective of this systematic review was to compare the effect of balanced versus unbalanced fluid bolus therapy on the mean change in serum bicarbonate or pH within 24 hours in critically ill children.

DATA SOURCES

We searched MEDLINE including Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Embase, CENTRAL Trials Registry of the Cochrane Collaboration, ClinicalTrials.gov, and World Health Organization International Clinical Trials Registry Platform.

STUDY SELECTION

Using the Preferred Reporting Items for Systematic Review and Meta-analysis Protocols guidelines, we retrieved all controlled trials and observational cohort studies comparing balanced and unbalanced resuscitative fluids in critically ill children. The primary outcome was the change in serum bicarbonate or blood pH. Secondary outcomes included the prevalence of hyperchloremia, acute kidney injury, renal replacement therapy, and mortality.

DATA EXTRACTION

Study screening, inclusion, data extraction, and risk of bias assessments were performed independently by two authors.

DATA SYNTHESIS

Among 481 references identified, 13 met inclusion criteria. In the meta-analysis of three randomized controlled trials with a population of 162 patients, we found a greater mean change in serum bicarbonate level (pooled estimate 1.60 mmol/L; 95% CI, 0.04-3.16; p = 0.04) and pH level (pooled mean difference 0.03; 95% CI, 0.00-0.06; p = 0.03) after 4-12 hours of rehydration with balanced versus unbalanced fluids. No differences were found in chloride serum level, acute kidney injury, renal replacement therapy, or mortality.

CONCLUSIONS

Our systematic review found some evidence of improvement in blood pH and bicarbonate values in critically ill children after 4-12 hours of fluid bolus therapy with balanced fluid compared with the unbalanced fluid. However, a randomized controlled trial is needed to establish whether these findings have an impact on clinical outcomes before recommendations can be generated.

Shifting the dynamics: implementation of locally driven, mixed-methods modelling to inform schistosomiasis control and elimination activities

INTRODUCTION

The integration of more diverse perspectives into the development of evidence for decision-making has been elusive, despite years of rhetoric to the contrary. This has led to cycles of population-based health interventions which have not delivered the promised results. The WHO most recently set a target for schistosomiasis elimination by 2030 and called for cross-cutting approaches to be driven by endemic countries themselves. The extent to which elimination is feasible within the time frame has been a subject of debate.

METHODS

Systems maps were developed through participatory modelling activities with individuals working on schistosomiasis control and elimination activities from the village through national levels in Uganda. These maps were first synthesised, then used to frame the form and content of subsequent mathematical modelling activities, and finally explicitly informed model parameter specifications for simulations, using the open-source SCHISTOX model, driven by the participants.

RESULTS

Based on the outputs of the participatory modelling, the simulation activities centred around reductions in water contact. The results of the simulations showed that mass drug administration, at either the current or target levels of coverage, combined with water contact reduction activities, achieved morbidity control in high prevalence Schistosoma mansoni settings, while both morbidity control and elimination were achieved in high prevalence S. haematobium settings within the 10-year time period.

CONCLUSION

The combination of participatory systems mapping and individual-based modelling was a rich strategy which explicitly integrated the perspectives of national and subnational policymakers and practitioners into the development of evidence. This strategy can serve as a method by which individuals who have not been traditionally included in modelling activities, and do not hold positions or work in traditional centres of power, may be heard and truly integrated into the development of evidence for decision-making in global health.

Open science communication: the first year of the UK's Independent Scientific Advisory Group for Emergencies

The COVID-19 pandemic has shone a light on the complex relationship between science and policy. Policymakers have had to make decisions at speed in conditions of uncertainty, implementing policies that have had profound consequences for people's lives. Yet this process has sometimes been characterised by fragmentation, opacity and a disconnect between evidence and policy. In the United Kingdom, concerns about the secrecy that initially surrounded this process led to the creation of Independent SAGE, an unofficial group of scientists from different disciplines that came together to ask policy-relevant questions, review the evolving evidence, and make evidence-based recommendations. The group took a public health approach with a population perspective, worked in a holistic transdisciplinary way, and were committed to public engagement. In this paper, we review the lessons learned during its first year. These include the importance of learning from local expertise, the value of learning from other countries, the role of civil society as a critical friend to government, finding appropriate relationships between science and policy, and recognising the necessity of viewing issues through an equity lens.

Negotiating Intersecting Precarities: COVID-19, Pandemic Preparedness and Response in Africa

This article shares findings on COVID-19 in Africa across 2020 to examine concepts and practices of epidemic preparedness and response. Amidst uncertainties about the trajectory of COVID-19, the stages of emergency response emerge in practice as interconnected. We illustrate how complex dynamics manifest as diverse actors interpret and modify approaches according to contexts and experiences. We suggest that the concept of "intersecting precarities" best captures the temporalities at stake; that these precarities include the effects of epidemic control measures; and that people do not just accept but actively negotiate these intersections as they seek to sustain their lives and livelihoods.

Crisis responses, opportunity, and public authority during Covid-19's first wave in Uganda, the Democratic Republic of Congo, and South Sudan

Discussions on African responses to Covid-19 have focused on the state and its international backers. Far less is known about a wider range of public authorities, including chiefs, humanitarians, criminal gangs, and armed groups. This paper investigates how the pandemic provided opportunities for claims to and contests over power in Uganda, the Democratic Republic of the Congo, and South Sudan. Ethnographic research is used to contend that local forms of public authority can be akin to miniature sovereigns, able to interpret dictates, policies, and advice as required. Alongside coping with existing complex protracted emergencies, many try to advance their own agendas and secure benefits. Those they seek to govern, though, do not passively accept the new normal, instead often challenging those in positions of influence. This paper assesses which of these actions and reactions will have lasting effects on local notions of statehood and argues for a public authorities lens in times of crisis.

564 Freedom from Urethral Catherisation – Using QI Methodology to Improve Patient Outcome and Experiences

Aim

To reduce catheter burden on patients who could instead be free of urethral catheter and taught intermittent self-catheterisation (ISC).

Method

2 PDSA (Plan, Do, Study, Act) cycles were performed over a 21-month period from February 2018 to November 2020. Using multiple nurse-led TWOC clinics, data was extracted using nurse-completed proformas and electronic patient records to determine: TWOC rate; urethral catheter-free rate; and ISC rate. Following baseline measurement, interventions were made, such as centralisation of TWOC services, emphasis on ISC teaching and the introduction of industry-nurse led clinics.

Results

At baseline, TWOC rate, urethral catheter-free rate and ISC rate were 55.7%, 68% and 28.2%, respectively. Following centralisation of TWOC services and emphasis on ISC teaching in Cycle 1, urethral catheter-free rate rose to 77.8% whilst ISC rate fell to 25%. Cycle 2 followed the introduction of industry-nurse led clinics. Following this, urethral catheter-free rate rose further to 81.6%, with ISC rate rising dramatically to 56.3%

Conclusions

To those capable, ISC frees patients of catheter burden and its sequalae. Evidently, a greater onus on ISC training will increase the number of patients left catheter-free.

(Re)arranging "systems of care" in the early Ebola response in Sierra Leone: An interdisciplinary analysis

Despite an expanding literature on Ebola-response, few studies detail or reflect on the responses of diverse systems of care. Little is known about how, why or in what ways, strategies of ill-health management were enacted locally, how health-systems power, authority and hierarchy were perceived and contested, or how other social systems, institutions and relationships shaped the response.

This paper presents an interdisciplinary analysis of local responses in two early affected districts in Sierra Leone. Drawing on anthropological theories of social ordering and assemblage, we present an analysis of contrasting infection chains in three extended case studies from Bo and Moyamba districts. In contrast to previous scholarship which has understood local actions as being reactive (supporting or obstructing) to a national Ebola response, we show that local arrangements lead and shape responses. Our cases show how multiple, entangled, dynamic and co-existing systems of care influence these responses. Some individuals and communities collaborated with health authorities on measures like reporting and quarantine, others actively opposed them, or played an intermediary role. Collectively, formal health systems actors, local authorities and ordinary citizens negotiated and enacted new arrangements. These arrangements involved compromise and sometimes power was reconfigured. They were also shaped by wider political and historical contexts and by availability or absence of formal healthcare resources. Our research shows the critical importance of understanding how institutions and people involved in healthcare enact diverse “systems of care” and thereby shape Ebola response. Most importantly, our work underlines the need for alignment between formal health-systems and wider social, cultural, political and economic forms of organisation at family and community levels to improve crisis-response and promote sustainable care. In particular, health systems responders need to identify and engage with key brokers – or arrangers – in frontline care systems, with whom mutually acceptable, and effective, reconfigurations of care can be achieved.

•

Multiple, dynamic, co-existing systems of care shaped Sierra Leone's Ebola response.

•

Political/historic context, resources, conflict and compromise all shaped care systems.

•

Diverse local actors negotiated relationships to reconfigure healthcare arrangements.

•

It is local arrangements that lead and shape crisis-response at the decentralised level.

•

Health systems need to engage with “arrangers” to reconfigure locally responsive care.

Legacies of humanitarian neglect: long term experiences of children who returned from the Lord's Resistance Army in Uganda

BACKGROUND

Much has been written about the short-term challenges facing children returning 'home' from rebel fighting groups, but little is known about the longer term day to day realities of return. This article presents findings from the first long-term assessment of the social and economic challenges facing an officially registered group of children who passed through an internationally-financed reception centre after a period of time with the Lord's Resistance Army (LRA).

METHODS

Records from a reception centre were used to trace a random sample of individuals to their current location. Two hundred and thirty in-depth semi-structured interviews were carried out and 40 follow-up interviews between 2013 and 2016. Interviews were informed by long-term ethnographic research in the region. These interviews were subsequently coded and analysed to describe the long-term day to day realities of return.

RESULTS

At the time of interview, 90% of formerly abducted people returned 'home' six or more years ago, and 75% returned nine or more years ago. The majority have managed to access family land for farming, but concerns about what they may have done to survive whilst living with the LRA adversely affects their day-to-day lives. However, some important differences were noted: those men and women who spent less time with the LRA are more likely to live on ancestral land with close relatives; and they are more likely to report experiencing stigma and a spiritual affliction called 'cen'. In contrast, those who spent the longest time with the LRA are less likely to report these problems, they are mainly living in urban locations and tend to manage slightly better. Children born of war are vulnerable to abuse, irrespective of current residence.

CONCLUSIONS

Research findings question the merits of post-conflict reintegration programmes emphasising immediate family reunifications, without follow-up monitoring, social protection, education and skills training. By overlooking the diverse experiences of those who lived and fought with the LRA, and failing to anticipate or respond to the long term socio-political and economic challenges facing children on their return, reception centre processes not only failed to foster social reintegration, but they also inadvertently exacerbated the vulnerability of returning children.

Analysis of survey on menstrual disorder among teenagers using Gaussian copula model with graphical lasso prior

A high prevalence of menstrual disturbance has been reported among teenage girls, and research shows that there are delays in diagnosis of endometriosis among young girls. Using data from the Menstrual Disorder of Teenagers Survey (administered in 2005 and 2016), we propose a Gaussian copula model with graphical lasso prior to identify cohort differences in menstrual characteristics and to predict endometriosis. The model includes random effects to account for clustering by school, and we use the extended rank likelihood copula model to handle variables of mixed-type. The graphical lasso prior shrinks the elements in the precision matrix of a Gaussian distribution to encourage a sparse graphical structure, where the level of shrinkage is adaptable based on the strength of the conditional associations among questions in the survey. Applying our proposed model to the menstrual disorder data set, we found that menstrual disturbance was more pronouncedly reported over a decade, and we found some empirical differences between those girls with higher risk of developing endometriosis and the general population.

Localising evidence for decision-making: participatory approach to inform schistosomiasis control

Background

The linear theories of change which ground many interventions do not account for the complex processes and systems in which they are implemented. This reductionist approach prioritises statistical methods which do not accommodate the stochastic, non-linear, dynamic interactions between humans and their environment. The inclusion of practitioners in the process of evidence development and utilisation of complex systems methods mitigates these issues and results in locally relevant, timely evidence for decision-making.

Methods

The aim of this work was to develop localised evidence for decision-making for schistosomiasis control in Uganda, Malawi, and Tanzania. Workshops were conducted with practitioners from the Ministries of Health at various levels and partner organisations to identify evidence needs for their decision-making processes and perceptions of disease transmission and control activities. Participatory systems mapping was used to identify factors directly and indirectly related to transmission. The maps were synthesised to a master complex systems map, which served as the blueprint for a generalised spatial agent-based model and specific ABMs tailored to the evidence needs of decision-makers.

Results

There was a gap in available evidence for practitioners to advocate for resources within the MoH and government budgets, as well as intervention efficacy and resource allocation. The adaptable and data-inclusive characteristics of the AMBs made them well-suited to produce localised outputs. Converted to NetLogo with a tailored user interface, these models were appropriate and responsive to the needs of decision-makers from village to national levels and across country contexts.

Conclusions

Used together, participatory and agent-based modelling resulted in the development of responsive and relevant evidence for practitioner decision-making. This process is generalisable and transferable to other diseases and locations outside of those in this study.

Key messages

The use of participatory systems mapping to develop agent-based models resulted in relevant and timely evidence for practitioner decision-making. The approach used here is transferable and generalisable outside schistosomiasis control and the contexts in this study.

Participatory systems mapping for localised evidence and decision-making: helminth control, SSA

Background

Evidence-informed decision-making to assist public health practitioners in local-level programme implementation requires adaptive approaches to research, policy and practice. To address these needs there is focus on using participatory methods. Adopting such methods, this research asks: what are the evidence needs of local public health practitioners? How do evidence and decision-making processes interact? We reflect on the process of using Participatory Systems Mapping (PSM) and implications for localising evidence-informed decision-making.

Methods

We conducted workshops with district and national-level MoH personnel in Uganda and Malawi using PSM to elicit insights into local modes of schistosomiasis transmission and control, and group discussions on evidence needs and use in implementing control programmes. PSM maps are analysed, triangulated with thematic analysis of group discussion transcripts.

Results

Analysing PSM outputs alongside discussions on evidence provides critical methodological and policy insights with implications for localised evidence and decision-making. Further insights into the local dynamics of public health decision-making are gained by triangulating PSM with discussions on the meanings and importance of 'factors' identified. Information which is accessible and useful for local practitioner's decision-making in implementing disease control measures does not always align with academic production and dissemination of evidence, nor across levels where policy is produced or implemented.

Conclusions

An array of factors influence local decision-making with implications for global health policies and practices such as for schistosomiasis control. Processes of decision-making and evidence needs of local practitioners need to be better understood within broader context. Evidence and knowledge production on health interventions rarely feedback or respond to local implementation needs, decision-making practices and public health practitioners.

Key messages

Processes of decision-making and evidence needs of local practitioners need to be better understood within broader context. Evidence and knowledge production on health interventions rarely feedback or respond to local implementation needs, decision-making practices and public health practitioners.

Investigating physiotherapy stakeholders' preferences for the development of performance-based assessment in practice education

OBJECTIVES

Discrete choice experiments (DCEs) are used in healthcare to measure the relative importance that stakeholders give to different features (or attributes) of medical treatments or services. They may also help to address research questions in health professional education. Several challenges exist regarding the performance-based assessment process (PBA) employed in physiotherapy practice-based education, a process which determines students' readiness for independent practice. Evidence highlights many commonalities among these challenges, but it is unknown which factors are the most important to stakeholders. The use of DCE methodology may provide answers and help to prioritise areas for development. Thus, this study employed DCE to identify clinical educators', practice tutors and physiotherapy students' preferences for developing the PBA process in physiotherapy.

DESIGN

Attributes (aspects of the PBA process known to be important to stakeholders) were derived from focus group interviews conducted with three groups; physiotherapy students, clinical educators (practising clinicians) and practice tutors (dedicated educational roles in the workplace). These attributes included the PBA tool, grading mechanisms, assessors involved, and, feedback mechanisms. Preferences for each group were calculated using a logistic regression model.

RESULTS

Seventy-two students, 124 clinical educators and 49 practice tutors (n=245) participated. Priorities identified centred primarily on the mandatory inclusion of two assessors in the PBA process and on refinement of the PBA tool.

CONCLUSION

Employment of DCE enabled the prioritisation of stakeholder-informed challenges related to PBA in physiotherapy practice-based education. This corroborates findings from previous qualitative work and facilitates a prioritised pathway for development of this process.

Modelling the pandemic: attuning models to their contexts

The evidence produced in mathematical models plays a key role in shaping policy decisions in pandemics. A key question is therefore how well pandemic models relate to their implementation contexts. Drawing on the cases of Ebola and influenza, we map how sociological and anthropological research contributes in the modelling of pandemics to consider lessons for COVID-19. We show how models detach from their implementation contexts through their connections with global narratives of pandemic response, and how sociological and anthropological research can help to locate models differently. This potentiates multiple models of pandemic response attuned to their emerging situations in an iterative and adaptive science. We propose a more open approach to the modelling of pandemics which envisages the model as an intervention of deliberation in situations of evolving uncertainty. This challenges the 'business-as-usual' of evidence-based approaches in global health by accentuating all science, within and beyond pandemics, as 'emergent' and 'adaptive'.

Impact of balanced versus unbalanced fluid resuscitation on clinical outcomes in critically ill children: protocol for a systematic review and meta-analysis

BACKGROUND

Isotonic crystalloid fluid bolus therapy is used in critically ill children to restore or maintain hemodynamic stability. However, the ideal choice of crystalloid remains to be determined. The most easily available and most frequently used crystalloid is 0.9% saline, an unbalanced crystalloid, that has been associated with hyperchloremic metabolic acidosis and acute kidney injury (AKI). Balanced fluids such as Ringer's lactate (RL) were developed to be closer to the composition of serum. However, they are more expensive and less readily available than 0.9% saline. Few trials have found RL to be associated with more favorable outcomes, but pediatric data is limited and inconsistent. The objective of the present systematic review is to review existing literature to determine the effect of balanced versus unbalanced fluid bolus therapy on metabolic acidosis in critically ill children.

METHODS

Using the Preferred Reporting Items for Systematic Review and Meta-analysis Protocols (PRISMA-P) guidelines, we will conduct a systematic review to retrieve all controlled trials and observational studies comparing balanced and unbalanced resuscitative fluids in critically ill children from age 28 days to 18 years old in any resuscitation settings. Search strategy was developed in collaboration with an experienced clinical research librarian. The primary outcome is the incidence and/or time to resolution of metabolic acidosis. Secondary outcomes included the incidence of hyperchloremia, AKI, duration of renal replacement therapy, vasopressors, mechanical ventilation, total volume of rehydration needed per day, extracorporeal membrane oxygenation, and length of stay and mortality. Study screening, inclusion, data extraction, and assessment of risk of bias will be performed independently by two authors. We intend to perform a meta-analysis with studies that are compatible on the basis of population and outcomes.

DISCUSSION

Isotonic crystalloid fluid bolus therapy is a ubiquitous treatment in resuscitation of critically ill pediatric patients and yet there is no clear recommendation to support the choice of balanced versus unbalanced fluid. The present review will summarize current available data in the literature and assess whether recommendations can be generated regarding the choice of crystalloids or otherwise identify knowledge gaps which will open the door to a large-scale randomized controlled trial (RCT).

Ebola and Public Authority: Saving Loved Ones in Sierra Leone

It is unclear how public authorities shaped responses to Ebola in Sierra Leone. Focusing on one village, we analyze what happened when “staff, stuff, space, and systems” were absent. Mutuality between neighbors, linked to secret societies, necessitated collective care for infected loved ones, irrespective of the risks. Practical learning was quick. Numbers recovering were reported to be higher among people treated in hidden locations, compared to those taken to Ebola Treatment Centres. Our findings challenge positive post-Ebola narratives about international aid and military deployment. A morally appropriate people’s science emerged under the radar of external scrutiny, including that of a paramount chief.

The Endometriosis Impact Questionnaire (EIQ): a tool to measure the long-term impact of endometriosis on different aspects of women's lives

Background

Endometriosis is a chronic disease impacting on many aspects of a woman’s life. Because of the chronic and recurring nature, many of the impacts of endometriosis could be missed using existing questionnaires which focus on recent events. Therefore, a questionnaire with a long-term perspective is necessary. This study aimed to develop and evaluate a questionnaire to measure the long-term impact of endometriosis on different aspects of women’s lives.

Methods

Through a methodological design, phase 1 was qualitative and phase 2 was a cross-sectional study. The original 100 EIQ items were developed based on results from an earlier qualitative study and literature review. Through a process of assessing face and content validity this was reduced to 66 items. The psychometric properties of the final 63 item EIQ were evaluated through a web-based survey with data from 423 responders with a self-reported surgically-diagnosed endometriosis.

Results

Participants were aged 16-58 years. Exploratory factor analysis of a 66-item EIQ was established with 423 responders. The final 63-item EIQ contained six dimensions including: 33-item physical-psychosocial; 3-item fertility; 7-item sexual; 11-item employment; 6-item educational; and 3-item lifestyle. Cronbach’s alpha of 0.99 for the whole 63-item EIQ, and 0.84 to 0.98 for the dimensions suggests a very good reliability. High positive correlations between the EIQ and the EHP-5 (altered recall period) indicated good evidence of concurrent validity. High intra-class correlations indicated very good test-retest reliability.

Conclusions

The EIQ, as a disease-specific questionnaire, could be used to provide a better understanding of the impact of endometriosis on different aspects of life, to better meet the needs of women. We recommend additional studies to establish validity evidence for the EIQ, including studies in other countries and languages.
