RESUMO
Evidence suggests children HIV-exposed and uninfected (CHEU) experience poor growth. We analysed child anthropometrics and explored factors associated with stunting among Malawian CHEU. Mothers with HIV and their infants HIV-exposed were enroled in a nationally representative prospective cohort within the National Evaluation of Malawi's Prevention of Mother-to-Child HIV Transmission Programme after Option B+ implementation (2014-2018). Anthropometry was measured at enrolment (age 1-6 months), visit 1 (approximately 12 months), and visit 2 (approximately 24 months). Weight-for-age (WAZ) and length-for-age (LAZ) z-scores were calculated using World Health Organization Growth Standards; underweight and stunting were defined as WAZ and LAZ more than 2 standard deviations below the reference median. Multivariable logistic regression restricted to CHEU aged 24 months (±3 months) was used to identify factors associated with stunting. Among 1211 CHEU, 562/1211 attended visit 2, of which 529 were aged 24 months (±3 months) and were included. At age 24 months, 40.4% of CHEU were stunted and/or underweight, respectively. In multi-variable analysis, adjusting for child age and sex, the odds of stunting were higher among CHEU with infectious disease diagnosis compared to those with no diagnosis (adjusted odds ratio = 3.35 [95% confidence interval: 1.82-6.17]), which was modified by co-trimoxazole prophylaxis (p = 0.028). Infant low birthweight was associated with an increased odds of stunting; optimal feeding and maternal employment were correlated with reduced odds. This is one of the first studies examining CHEU growth since Option B+. Interventions to improve linear growth among CHEU should address their multi-faceted health risks, alongside maternal ART prescription, and follow-up of mother-child pairs.

BACKGROUND: Patients who present to an emergency department (ED) with respiratory symptoms are often conservatively triaged in favour of hospitalisation. We sought to determine if an inflammatory biomarker panel that identifies the host response better predicts hospitalisation in order to improve the precision of clinical decision making in the ED. METHODS: From April 2020 to March 2021, plasma samples of 641 patients with symptoms of respiratory illness were collected from EDs in an international multicentre study: Canada (n=310), Italy (n=131) and Brazil (n=200). Patients were followed prospectively for 28â days. Subgroup analysis was conducted on confirmed coronavirus disease 2019 (COVID-19) patients (n=245). An inflammatory profile was determined using a rapid, 50-min, biomarker panel (RALI-Dx (Rapid Acute Lung Injury Diagnostic)), which measures interleukin (IL)-6, IL-8, IL-10, soluble tumour necrosis factor receptor 1 (sTNFR1) and soluble triggering receptor expressed on myeloid cells 1 (sTREM1). RESULTS: RALI-Dx biomarkers were significantly elevated in patients who required hospitalisation across all three sites. A machine learning algorithm that was applied to predict hospitalisation using RALI-Dx biomarkers had a mean±sd area under the receiver operating characteristic curve of 76±6% (Canada), 84±4% (Italy) and 86±3% (Brazil). Model performance was 82±3% for COVID-19 patients and 87±7% for patients with a confirmed pneumonia diagnosis. CONCLUSIONS: The rapid diagnostic biomarker panel accurately identified the need for inpatient care in patients presenting with respiratory symptoms, including COVID-19. The RALI-Dx test is broadly and easily applicable across many jurisdictions, and represents an important diagnostic adjunct to advance ED decision-making protocols.

OBJECTIVES: Data on long-term HIV-free survival in breastfeeding, HIV-exposed infants (HEIs) are limited. The National Evaluation of Malawi's Prevention of Mother-to-Child Transmission (PMTCT) Program (NEMAPP), conducted between 2014 and 2018, evaluated mother-to-child transmission (MTCT) and infant outcomes up to 24 months postpartum. METHODS: We enrolled a nationally representative cohort of HEIs at 54 health facilities across four regional strata in Malawi and used multivariable Cox regression analysis to investigate the risk of adverse outcomes (HIV transmission, infant death and loss to follow-up) to 24 months postpartum. Models, controlling for survey design, were fitted for the total cohort (n = 3462) and for a subcohort that received maternal viral load (VL) monitoring (n = 1282). RESULTS: By 24 months, in 3462 HEIs, weighted cumulative MTCT was 4.9% [95% confidence interval (CI) 3.7-6.4%], 1.3% (95% CI 0.8-2.2%) of HEIs had died, 26.2% (95% CI 24.0-28.6%) had been lost to follow-up and 67.5% (95% CI 65.0-70.0%) were alive and HIV-free. Primiparity [weighted adjusted hazard ratio (aHR) 1.6; 95% CI 1.1-2.2; parity 2-3: weighted aHR 1.5; 95% CI 1.2-1.9], the mother not disclosing her HIV status to her partner (no disclosure: weighted aHR 1.3; 95% CI 1.1-1.6; no partner: weighted aHR 0.7; 95% CI 0.5-0.9), unknown maternal ART start (weighted aHR 2.0; 95% CI 1.0-3.9) and poor adherence (missed ≥ 2 days of ART in the last month: weighted aHR 1.7; 95% CI 1.2-2.2; not on ART: weighted aHR 1.7; 95% CI 1.0-2.7) were associated with adverse outcomes by 24 months. In the subcohort analysis, risk of HIV transmission or infant death was higher among HEIs whose mothers started ART post-conception (during pregnancy: weighted aHR 3.2; 95% CI 1.3-7.7; postpartum: weighted aHR 12.4; 95% CI 1.5-99.6) or when maternal viral load at enrolment was > 1000 HIV-1 RNA copies/mL (weighted aHR 15.7; 95% CI 7.8-31.3). CONCLUSIONS: Infant positivity and infant mortality at 24 months were low for a breastfeeding population. Starting ART pre-conception had the greatest impact on HIV-free survival in HEIs. Further population-level reduction in MTCT may require additional intervention during breastfeeding for women new to PMTCT programmes. Pre-partum diagnosis and linkage to ART, followed by continuous engagement in care during breastfeeding can further reduce MTCT but are challenging to implement.

Significant evidence identifies point-of-care ultrasound (PoCUS) as an important diagnostic and therapeutic tool in resource-limited settings. Despite this evidence, local health care providers on the African continent continue to have limited access to and use of ultrasound, even in potentially high-impact fields such as obstetrics and trauma. Dedicated postgraduate emergency medicine residency training programs now exist in 8 countries, yet no current consensus exists in regard to core PoCUS competencies. The current practice of transferring resource-rich PoCUS curricula and delivery methods to resource-limited health systems fails to acknowledge the unique challenges, needs, and disease burdens of recipient systems. As emergency medicine leaders from 8 African countries, we introduce a practical algorithmic approach, based on the local epidemiology and resource constraints, to curriculum development and implementation. We describe an organizational structure composed of nexus learning centers for PoCUS learners and champions on the continent to keep credentialing rigorous and standardized. Finally, we put forth 5 key strategic considerations: to link training programs to hospital systems, to prioritize longitudinal learning models, to share resources to promote health equity, to maximize access, and to develop a regional consensus on training standards and credentialing.

BACKGROUND: HIV treatment models in Africa are labour intensive and require a high number of skilled staff. In this context, task-shifting is considered a feasible alternative for ART service delivery. In 2006, a lay health cadre of expert patients (EPs) at a tertiary referral HIV clinic in Zomba, Malawi was capacitated. There are few evaluations of EP program efficacy in this setting. Triage is the process of prioritizing patients in terms of the severity of their condition and ensures that no harmful delays occur to treatment and care. This study evaluates the safety of task-shifting triage, in an ambulatory low resource setting, to EPs. METHODS: As a quality improvement exercise in April 2010, formal triage training was conducted by adapting the World Health Organization Emergency Triage Assessment and Treatment Triage Module Guidelines. A cross sectional observation study was conducted 2 years after the intervention. Triage assessments performed by EPs were repeated by a clinical officer (gold standard) to assess sensitivities, specificities, positive and negative predictive values for EP triage scores. Proportions were calculated for categories of disposition by stratifying by EP and clinician triage scores. RESULTS: A total of 467 patients were triaged by 7 EPs and re-triaged by clinical officers. With combined triage scores for emergency and priority patients we report a sensitivity of 85% and specificity of 74% for the EP scoring, with a low positive predictive value (41%) and a high negative predictive value (96%). We calculate a serious miss rate of EP scoring (i.e. missed priority or emergency patients) as 2.2%. Admission rates to hospital were highest among those patients triaged as emergency cases either by the EP's (21%) or the clinicians (83%). Fewer patients triaged as priority by either EPs (5%) or clinicians (15%) were admitted to hospital, however these patients had the highest prevalence of same day lab testing and/or specialty referral. CONCLUSIONS: Our study provides reassurance that in the context of adequate training and ongoing supervision, task-shifting triage to lay health care workers does not necessarily lead to less accurate triaging. EPs have a tendency to be more conservative in over-triaging patients.

BACKGROUND: Chronic diseases, primarily cardiovascular disease, respiratory disease, diabetes and cancer, are the leading cause of death and disability worldwide. In sub-Saharan Africa (SSA), where communicable disease prevalence still outweighs that of non-communicable disease (NCDs), rates of NCDs are rapidly rising and evidence for primary healthcare approaches for these emerging NCDs is needed. METHODS: A systematic review and evidence synthesis of primary care approaches for chronic disease in SSA. Quantitative and qualitative primary research studies were included that focused on priority NCDs interventions. The method used was best-fit framework synthesis. RESULTS: Three conceptual models of care for NCDs in low- and middle-income countries were identified and used to develop an a priori framework for the synthesis. The literature search for relevant primary research studies generated 3759 unique citations of which 12 satisfied the inclusion criteria. Eleven studies were quantitative and one used mixed methods. Three higher-level themes of screening, prevention and management of disease were derived. This synthesis permitted the development of a new evidence-based conceptual model of care for priority NCDs in SSA. CONCLUSIONS: For this review there was a near-consensus that passive rather than active case-finding approaches are suitable in resource-poor settings. Modifying risk factors among existing patients through advice on diet and lifestyle was a common element of healthcare approaches. The priorities for disease management in primary care were identified as: availability of essential diagnostic tools and medications at local primary healthcare clinics and the use of standardized protocols for diagnosis, treatment, monitoring and referral to specialist care.

The influence of HIV-related stigma on women's choices with regard to HIV testing, disclosure and partner involvement in infant feeding and care is not well understood in rural Malawi but may influence the risk of vertical HIV transmission and infant health. In a study of HIV-infected and -uninfected women in 20 rural locations in Zomba District, Malawi, mothers were questioned at 18-20 months post-partum about these issues. Ten per cent of women claimed unknown HIV status in labour so HIV testing should be routinely offered in Labour & Delivery wards. HIV-infected women were somewhat less likely to disclose to their partners than HIV-uninfected women (89 and 97%, respectively; p = 0.007) or to be cohabiting with partners during pregnancy (74 and 86%, respectively; p = 0.03). Partners of women were less inclined to disclose their HIV testing or HIV status (49 and 66% of partners of HIV-infected and -uninfected women, respectively). Greater partner testing and disclosure may improve prevention of mother to child transmission of HIV (PMTCT) in this population. A majority of women were inclined to make feeding decisions on their own, whereas most felt that other health-related decisions should also involve the father. Most mothers believe that exclusive breast feeding (EBF) is the best infant feeding method (for the first six months) but it was actually practiced by a minority of women (20% of HIV-infected and 5% of HIV-uninfected mothers; p = 0.01). EBF needs systematic support in order to be practised.

It is common for universities to form academic partnerships to strengthen their provision of educational opportunities for the faculty and staff at both institutions. These efforts are occasionally done, particularly in north-south partnerships, by partners with different means. As such, unless a true spirit of collaboration is sought, agreed upon, and both parties given equal authority to determine its success, imbalances can prevent each from achieving its goal. Using a collaboration between Addis Ababa University and the University of Toronto as an example, the facets of what makes an appropriate and successful partnership are explored, and outcomes that are meaningful to both institutions described.

INTRODUCTION: Globally Emergency Medicine (EM) is young discipline and even in developed countries it is about five decades old. In Ethiopia formal pre-hospital care or hospital based Emergency department (ED) development is a recent phenomenon and this article describes development of Emergency Medicine care in Ethiopia before, around and after Ethiopia millennium. METHODOLOGY: Documents related to emergency medicine development and implementation from different government and nongovernmental data sources are used as a resource for this article. RESULTS: Emergency Medicine task force (EMTF) has been established in Addis Ababa University (AAU) school of Medicine (SOM) in June 2006 and the taskforce has closely worked with Federal Ministry of Health (FMOH) and Addis Ababa city council Health Bureau (AACCHB). In addition to the main actors many partners have contributed significantly to this initiative. Some of the developments were establishment of emergency departments in Tikur Anbessa Specialized Hospital (TASH) and the restructuring of EM service by FMOH. Emergency care has been considered as a crucial service in hospitals' service along with outpatient and inpatient services. Furthermore, Pre-hospital care initiatives have been commenced in Addis Ababa and expanded to the regions with a arrangement of one or two ambulances to small districts having 100,000 population. There have also been key achievement in human resource development, notably the establishment of EM residency and MSC in EM and critical care nursing. Prehospital care givers training programs in order to produce emergency medicine technicians (EMT) have been started in various regional health professionals training centers. Furthermore, EM module has been included in the current undergraduate medical education. The Ethiopian society of emergency professionals (ESEP) has been established with members from different categories of emergency medicine professionals. In all these developments the emergency medicine training center in the emergency department of AAU has played key role in the training of human resources in different categories. DISCUSSION AND CONCLUSION: The recent successes in EM development is due to concerted efforts of the FMOH, AAU SOM and AACCHB along with committed partners. Hence, it is concluded that consistent local efforts and relevant stakeholders support in EM has resulted in successful development of the field in the country.

OBJECTIVES: 1 in 7 Canadians with Human Immunodeficiency Virus (HIV) do not know their status. Patients at increased risk of HIV routinely access the emergency department (ED), yet few are tested, representing a missed opportunity for diagnosis and linkage-to-care. Rapid HIV testing provides reliable results within the same ED encounter but is not routinely implemented. The objective of this study was to identify barriers and facilitators to rapid HIV testing in Ontario EDs. METHODS: We employed a mixed-methods, convergent, parallel design study including online surveys and semi-structured interviews of physicians, nurses, and allied health across four hospitals in Toronto and Thunder Bay, Ontario. Data were analyzed in equal priority using descriptive statistics for quantitative data and thematic analysis for qualitative data guided by the Theoretical Domains framework and Capability, Opportunity, Motivation Behaviour change model. RESULTS: Among 187 survey respondents, 150 (80%) felt implementing rapid HIV testing would be helpful in the ED. Facilitators included availability of resources to link patients to care after testing (71%), testing early in patient encounters (41%), and having dedicated staff with lived experience support testing (34%). Motivation to offer testing included opportunities to support an underserved population (66%). Challenges to implementation included limited time during ED patient encounters (51%) and a lack of knowledge around HIV testing (42%) including stigma. Interview themes confirmed education, and integration of people with lived experience being essential to provide rapid HIV testing and linkage-to-care in the ED. CONCLUSIONS: Implementation of rapid HIV testing in the ED is perceived to be important irrespective of practice location or profession. Intrinsic motivations to support underserved populations and providing linkage-to-care are novel insights to facilitate testing in the ED. Streamlined implementation, including clear testing guidelines and improved access to follow-up care, is felt to be necessary for implementation.
ABSTRAIT: OBJECTIFS: 1 Canadien sur 7 atteint du virus de l'immunodéficience humaine (VIH) ne connaît pas son statut. Les patients présentant un risque accru de contracter le VIH ont régulièrement accès au service des urgences (SU), mais peu d'entre eux sont testés, ce qui représente une occasion manquée de diagnostic et de lien avec les soins. Le dépistage rapide du VIH fournit des résultats fiables dans la même situation d'urgence, mais n'est pas systématiquement mis en Åuvre. L'objectif de cette étude était d'identifier les obstacles et les facilitateurs au dépistage rapide du VIH dans les urgences de l'Ontario. MéTHODES: Nous avons utilisé une étude de conception mixte, convergente et parallèle, y compris des sondages en ligne et des entrevues semi-structurées auprès de médecins, d'infirmières et d'auxiliaires de la santé dans quatre hôpitaux de Toronto et de Thunder Bay, en Ontario. Les données ont été analysées en priorité égale à l'aide de statistiques descriptives pour les données quantitatives et d'analyses thématiques pour les données qualitatives guidées par le cadre des domaines théoriques et le modèle de changement de capacité, d'opportunité et de motivation. RéSULTATS: Parmi 187 répondants au sondage, 150 (80 %) étaient d'avis que la mise en Åuvre d'un dépistage rapide du VIH serait utile à l'urgence. Les facilitateurs comprenaient la disponibilité de ressources pour lier les patients aux soins après le test (71 %), le dépistage précoce lors des rencontres avec les patients (41 %) et la présence d'un personnel dévoué avec des tests de soutien de l'expérience vécue (34 %). La motivation à offrir des tests comprenait des occasions de soutenir une population mal desservie (66 %). Les difficultés de mise en Åuvre comprenaient un temps limité pendant les rencontres avec les patients aux urgences (51 %) et un manque de connaissances sur le dépistage du VIH (42 %), y compris la stigmatisation. Les thèmes des entrevues ont confirmé que l'éducation et l'intégration des personnes ayant une expérience vécue sont essentielles pour fournir un dépistage rapide du VIH et un lien avec les soins aux urgences. CONCLUSIONS: La mise en Åuvre du dépistage rapide du VIH aux urgences est perçue comme importante, quel que soit le lieu de pratique ou la profession. Les motivations intrinsèques à soutenir les populations mal desservies et à fournir un lien avec les soins sont de nouvelles idées pour faciliter les tests à l'urgence. Une mise en Åuvre simplifiée, y compris des lignes directrices claires sur les tests et un meilleur accès aux soins de suivi, est jugée nécessaire pour la mise en Åuvre.

RESUMO
BACKGROUND: In 2011, Malawi initiated an ambitious program for the prevention of maternal to child transmission (PMTCT) of HIV, called 'Option B+,' which employs a universal test and life-long treatment strategy for all pregnant women. Priority setting should take place in defining a national research agenda for evaluating Option B + rollout in Malawi. METHODS: In April 2011, a three-day workshop took place for all major stakeholders in PMTCT aiming to provide an update on current PMTCT operational research in Malawi, find consensus on key questions not yet being addressed, identify opportunities for collaboration, and develop multi-partner research proposals. RESULTS: Overall, 24 participants attended the workshop including representatives from the Ministry of Health, the National AIDS Commission and 12 multilateral, non-governmental organizations and academic partners.Three interrelated clusters emerged as priorities for research: i) pregnancy intentions and family planning needs; ii) evaluation of models of care; and iii) determinants of uptake, adherence, and retention of women for Option B+. In addition, two cross-cutting themes arose: partner involvement in PMTCT services and cost-effectiveness as a guide to priority setting. Within each cluster a coordinator was designated and a proposed plan for research and potential collaborators were discussed. The results of the workshop were presented to the national technical working groups and the National AIDS Commission. Several large-scale, collaborative proposals have been developed and funded to address the research areas defined. CONCLUSIONS: Option B + represents a significant change in PMTCT policy in Malawi and the process for evaluation of the Malawi PMTCT strategy is outlined. This workshop contributed to defining and coordinating the national agenda for research priorities.

BACKGROUND: Avoidance of care during the pandemic may have contributed to delays in care, and as a result, worse patient outcomes. We evaluated markers of illness acuity on presentation to the emergency department among patients with non-COVID-19-related emergent diagnoses and associated outcomes. METHODS: We conducted a retrospective study using linked administrative data from Ontario. We selected 4 emergent diagnoses, namely appendicitis, ectopic pregnancy, renal failure and diabetic ketoacidosis. We used the nonemergent diagnosis of cellulitis as a control. Our primary outcome of interest was hospital admission. Secondary outcomes were ambulance arrival, surgical intervention, subsequent hospital admission within 30 days of discharge from the emergency department or hospital and 30-day mortality. We compared outcomes during the first year of the COVID-19 pandemic (Mar. 15-Dec. 31, 2020) with a control period (Mar. 15-Dec. 31, 2018, and Mar. 15-Dec. 31, 2019). RESULTS: Emergency department visits for all conditions initially decreased during the pandemic. During this period, patients across all study diagnoses were more likely to arrive to the emergency department via ambulance. Patients with an ectopic pregnancy had higher odds of surgery in the pandemic period (odds ratio [OR] 1.27, 95% confidence interval [CI] 1.04-1.55) but this was not observed among patients with appendicitis. Patients with renal failure had increased odds of hospital admission (OR 1.14, 95% CI 1.04-1.24) and 30-day mortality (OR 1.17, 95% CI 1.04-1.31) during the pandemic period. INTERPRETATION: The pandemic period was associated with increased arrival to the emergency department via ambulance across all study diagnoses. Although patients with renal failure had increased hospital admission and death, and patients with ectopic pregnancy had an increased risk of surgery, there were no differences in outcomes for other populations, suggesting the health care system was able to care for these patients effectively.
RESUMO
India has one of the most unequal healthcare systems globally, lagging behind its economic development. Improved primary care and primary health care play an integral role in overcoming health disparities. Family medicine is a subset of primary care-delivered by family physicians, characterized by comprehensive, continuous, coordinated, collaborative, personal, family and community-oriented services-and may be able to fill these gaps. This research aims to understand the potential mechanisms by which family physicians can strengthen primary health care. In this qualitative descriptive study, we interviewed twenty family physicians, identified by purposeful and snowball sampling, who are among the first family physicians in India who received accredited certification in FM and were identified as pioneers of family medicine. We used the Contribution of Family Medicine to Strengthening Primary Health Care Framework to understand the potential mechanisms by which family medicine strengthens primary health care. Iterative inductive techniques were used for analysis. This research identifies multiple ways family physicians can strengthen primary health care in India. They are skilled primary care providers and support mid and low-level health care providers' ongoing training and capacity building. They develop relationships with specialists, ensure appropriate referral systems are in place, and, when necessary, work with governments and organizations to access the essential resources needed to deliver care. They motivate the workforce and change how care is delivered by ensuring providers' skills match the needs of communities and engage communities as partners in healthcare delivery. These findings highlight multiple mechanisms by which family physicians strengthen primary health care. Investments in postgraduate training in family medicine and integrating family physicians into the primary care sector, particularly the public sector, could address health disparities.
RESUMO
Countries globally are introducing family medicine to strengthen primary health care; however, for many, that process has been slow. Understanding the implementation of family medicine in a national context is complex but critical to uncovering what worked, the challenges faced, and how the process can be improved. This study explores how family medicine was implemented in India and how early cohort family physicians supported the field's emergence. In this qualitative descriptive study, we interviewed twenty family physicians who were among the first in India and recognized as pioneers. We used Rogers's Diffusion of Innovation Theory to describe and understand the roles of family physicians, as innovators and early adopters, in the process of implementation. Greenhalgh's Model of Diffusion in Service Organizations is applied to identify barriers and enablers to family medicine implementation. This research identifies multiple mechanisms by which pioneering family physicians supported the implementation of family medicine in India. They were innovators who developed the first family medicine training programs. They were early adopters willing to enter a new field and support spread as educators and mentors for future cohorts of family physicians. They were champions who developed professional organizations to bring together family physicians to learn from one another. They were advocates who pushed the medical community, governments, and policymakers to recognize family medicine's role in healthcare. Facilitators for implementation included the supportive environment of academic institutions and the development of family medicine professional organizations. Barriers to implementation included the lack of government support and awareness of the field by society, and tension with subspecialties. In India, the implementation of family medicine has primarily occurred through pioneering family physicians and supportive educational institutions. For family medicine to continue to grow and have the intended impacts on primary care, government and policymaker support are needed.
RESUMO
INTRODUCTION: Not all patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection develop symptomatic coronavirus disease 2019 (COVID-19), making it challenging to assess the burden of COVID-19-related hospitalizations and mortality. We aimed to determine the proportion, resource utilization, and outcomes of SARS-CoV-2 positive patients admitted for COVID-19, and assess the impact of using the Center for Disease Control's (CDC) discharge diagnosis-based algorithm and the Massachusetts state department's drug administration-based classification system on identifying admissions for COVID-19. METHODS: In this retrospective cohort study, we enrolled consecutive SARS-CoV-2 positive patients admitted to one of five hospitals in British Columbia between December 19, 2021 and May 31,2022. We completed medical record reviews, and classified hospitalizations as being primarily for COVID-19 or with incidental SARS-CoV-2 infection. We applied the CDC algorithm and the Massachusetts classification to estimate the difference in hospital days, intensive care unit (ICU) days and in-hospital mortality and calculated sensitivity and specificity. RESULTS: Of 42,505 Emergency Department patients, 1,651 were admitted and tested positive for SARS-CoV-2, with 858 (52.0%, 95% CI 49.6-54.4) admitted for COVID-19. Patients hospitalized for COVID-19 required ICU admission (14.0% versus 8.2%, p<0.001) and died (12.6% versus 6.4%, p<0.001) more frequently compared with patients with incidental SARS-CoV-2. Compared to case classification by clinicians, the CDC algorithm had a sensitivity of 82.9% (711/858, 95% CI 80.3%, 85.4%) and specificity of 98.1% (778/793, 95% CI 97.2%, 99.1%) for COVID-19-related admissions and underestimated COVID-19 attributable hospital days. The Massachusetts classification had a sensitivity of 60.5% (519/858, 95% CI 57.2%, 63.8%) and specificity of 78.6% (623/793, 95% CI 75.7%, 81.4%) for COVID-19-related admissions, underestimating total number of hospital and ICU bed days while overestimating COVID-19-related intubations, ICU admissions, and deaths. CONCLUSION: Half of SARS-CoV-2 hospitalizations were for COVID-19 during the Omicron wave. The CDC algorithm was more specific and sensitive than the Massachusetts classification, but underestimated the burden of COVID-19 admissions. TRIAL REGISTRATION: Clinicaltrials.gov, NCT04702945.

Background: With the implementation of lifelong antiretroviral therapy (ART) for HIV treatment and prevention, the proportion of children exposed to ART in utero from conception is increasing. We estimated the effect of timing of ART exposure on growth of children HIV-exposed and uninfected (CHEU) up to Up to 24 months of age in Malawi. Methods: Data were collected from a prospective cohort of infants HIV-exposed aged 1-6 months (enrollment) and their mothers with HIV enrolled in the National Evaluation of Malawi's Prevention of Mother-to-Child Transmission of HIV Programme (2014-2018). Anthropometry was measured at enrollment, visit 1 (approximately 12 months), and visit 2 (approximately 24 months). Weight-for-age (WAZ) and length-for-age (LAZ) were calculated using the WHO Growth Standards. Multivariable mixed-effects models with linear splines for age were used to examine differences in growth by timing of ART exposure (from conception, first/second trimester, or third trimester/postpartum). Models were adjusted for confounders selected a priori guided by a conceptual framework. Hypothesized interactions and potential mediators were explored, and interactions with splines were included in final models if P < 0.1. Results: A total of 1,206 singleton CHEU and their mothers were enrolled and 563 completed the follow-up through 24 months of age. Moreover, 48% of CHEU were exposed to ART from conception, 40% from first/second trimester, and 12% from third trimester/postpartum. At enrollment, 12% of infants had low birthweight (LBW), 98% had been breastfed in past 7 days, and 57% were enrolled in an HIV care clinic. CHEU growth trajectories demonstrated cohort-wide growth faltering after the age of 12 months. Of 788 and 780 CHEU contributing to WAZ and LAZ multivariable models, respectively, there was no evidence of differences in mean WAZ or LAZ among those exposed from conception or first/second trimester vs. third trimester/postpartum and no evidence of a difference in WAZ or LAZ rate of change by timing of ART exposure (all interactions P > 1.0). Conclusion: Reassuringly, ART exposure from conception was not associated with decreased WAZ or LAZ in CHEU Up 24 months of age. Overall growth trajectories suggest CHEU experience growth faltering after 12 months of age and may need support through and beyond the first 2 years of life.
