Early effects of COVID-19 on maternal and child health service disruption in Mozambique

This article is part of the Research Topic ‘Health Systems Recovery in the Context of COVID-19 and Protracted Conflict'IntroductionAfter the World Health Organization declared COVID-19 a pandemic, more than 184 million cases and 4 million deaths had been recorded worldwide by July 2021. These are likely to be underestimates and do not distinguish between direct and indirect deaths resulting from disruptions in health care services. The purpose of our research was to assess the early impact of COVID-19 in 2020 and early 2021 on maternal and child healthcare service delivery at the district level in Mozambique using routine health information system data, and estimate associated excess maternal and child deaths.MethodsUsing data from Mozambique's routine health information system (SISMA, Sistema de Informação em Saúde para Monitoria e Avaliação), we conducted a time-series analysis to assess changes in nine selected indicators representing the continuum of maternal and child health care service provision in 159 districts in Mozambique. The dataset was extracted as counts of services provided from January 2017 to March 2021. Descriptive statistics were used for district comparisons, and district-specific time-series plots were produced. We used absolute differences or ratios for comparisons between observed data and modeled predictions as a measure of the magnitude of loss in service provision. Mortality estimates were performed using the Lives Saved Tool (LiST).ResultsAll maternal and child health care service indicators that we assessed demonstrated service delivery disruptions (below 10% of the expected counts), with the number of new users of family planing and malaria treatment with Coartem (number of children under five treated) experiencing the largest disruptions. Immediate losses were observed in April 2020 for all indicators, with the exception of treatment of malaria with Coartem. The number of excess deaths estimated in 2020 due to loss of health service delivery were 11,337 (12.8%) children under five, 5,705 (11.3%) neonates, and 387 (7.6%) mothers.ConclusionFindings from our study support existing research showing the negative impact of COVID-19 on maternal and child health services utilization in sub-Saharan Africa. This study offers subnational and granular estimates of service loss that can be useful for health system recovery planning. To our knowledge, it is the first study on the early impacts of COVID-19 on maternal and child health care service utilization conducted in an African Portuguese-speaking country

Assessment of measles immunity among infants in Maputo City, Mozambique

<p>Abstract</p> <p>Background</p> <p>The optimum age for measles vaccination varies from country to country and thus a standardized vaccination schedule is controversial. While the increase in measles vaccination coverage has produced significant changes in the epidemiology of infection, vaccination schedules have not been adjusted. Instead, measures to cut wild-type virus transmission through mass vaccination campaigns have been instituted. This study estimates the presence of measles antibodies among six- and nine-month-old children and assesses the current vaccination seroconversion by using a non invasive method in Maputo City, Mozambique.</p> <p>Methods</p> <p>Six- and nine-month old children and their mothers were screened in a cross-sectional study for measles-specific antibodies in oral fluid. All vaccinated children were invited for a follow-up visit 15 days after immunization to assess seroconversion. </p> <p>Results</p> <p>82.4% of the children lost maternal antibodies by six months. Most children were antibody-positive post-vaccination at nine months, although 30.5 % of nine month old children had antibodies in oral fluid before vaccination. We suggest that these pre-vaccination antibodies are due to contact with wild-type of measles virus. The observed seroconversion rate after vaccination was 84.2%. </p> <p>Conclusion</p> <p>These data indicate a need to re-evaluate the effectiveness of the measles immunization policy in the current epidemiological scenario.</p

Association of diabetes, smoking, and alcohol use with subclinical-to-symptomatic spectrum of tuberculosis in 16 countries: an individual participant data meta-analysis of national tuberculosis prevalence surveys

Summary Background Non-communicable diseases (NCDs) and NCD risk factors, such as smoking, increase the risk for tuberculosis (TB). Data are scarce on the risk of prevalent TB associated with these factors in the context of population-wide systematic screening and on the association between NCDs and NCD risk factors with different manifestations of TB, where ∼50% being asymptomatic but bacteriologically positive (subclinical). We did an individual participant data (IPD) meta-analysis of national and sub-national TB prevalence surveys to synthesise the evidence on the risk of symptomatic and subclinical TB in people with NCDs or risk factors, which could help countries to plan screening activities. Methods In this systematic review and IPD meta-analysis, we identified eligible prevalence surveys in low-income and middle-income countries that reported at least one NCD (e.g., diabetes) or NCD risk factor (e.g., smoking, alcohol use) through the archive maintained by the World Health Organization and by searching in Medline and Embase from January 1, 2000 to August 10, 2021. The search was updated on March 23, 2023. We performed a one-stage meta-analysis using multivariable multinomial models. We estimated the proportion of and the odds ratio for subclinical and symptomatic TB compared to people without TB for current smoking, alcohol use, and self-reported diabetes, adjusted for age and gender. Subclinical TB was defined as microbiologically confirmed TB without symptoms of current cough, fever, night sweats, or weight loss and symptomatic TB with at least one of these symptoms. We assessed heterogeneity using forest plots and I2 statistic. Missing variables were imputed through multi-level multiple imputation. This study is registered with PROSPERO (CRD42021272679). Findings We obtained IPD from 16 national surveys out of 21 national and five sub-national surveys identified (five in Asia and 11 in Africa, N = 740,815). Across surveys, 15.1%–56.7% of TB were subclinical (median: 38.1%). In the multivariable model, current smoking was associated with both subclinical (OR 1.67, 95% CI 1.27–2.40) and symptomatic TB (OR 1.49, 95% CI 1.34–1.66). Self-reported diabetes was associated with symptomatic TB (OR 1.67, 95% CI 1.17–2.40) but not with subclinical TB (OR 0.92, 95% CI 0.55–1.55). For alcohol drinking ≥ twice per week vs no alcohol drinking, the estimates were imprecise (OR 1.59, 95% CI 0.70–3.62) for subclinical TB and OR 1.43, 95% CI 0.59–3.46 for symptomatic TB). For the association between current smoking and symptomatic TB, I2 was high (76.5% (95% CI 62.0–85.4), while the direction of the point estimates was consistent except for three surveys with wide CIs. Interpretation Our findings suggest that current smokers are more likely to have both symptomatic and subclinical TB. These individuals can, therefore, be prioritised for intensified screening, such as the use of chest X-ray in the context of community-based screening. People with self-reported diabetes are also more likely to have symptomatic TB, but the association is unclear for subclinical TB

Tobacco smoking clusters in households affected by tuberculosis in an individual participant data meta-analysis of national tuberculosis prevalence surveys: Time for household-wide interventions?

Tuberculosis (TB) and non-communicable diseases (NCD) share predisposing risk factors. TB-associated NCD might cluster within households affected with TB requiring shared prevention and care strategies. We conducted an individual participant data meta-analysis of national TB prevalence surveys to determine whether NCD cluster in members of households with TB. We identified eligible surveys that reported at least one NCD or NCD risk factor through the archive maintained by the World Health Organization and searching in Medline and Embase from 1 January 2000 to 10 August 2021, which was updated on 23 March 2023. We compared the prevalence of NCD and their risk factors between people who do not have TB living in households with at least one person with TB (members of households with TB), and members of households without TB. We included 16 surveys (n = 740,815) from Asia and Africa. In a multivariable model adjusted for age and gender, the odds of smoking was higher among members of households with TB (adjusted odds ratio (aOR) 1.23; 95% CI: 1.11–1.38), compared with members of households without TB. The analysis did not find a significant difference in the prevalence of alcohol drinking, diabetes, hypertension, or BMI between members of households with and without TB. Studies evaluating household-wide interventions for smoking to reduce its dual impact on TB and NCD may be warranted. Systematically screening for NCD using objective diagnostic methods is needed to understand the actual burden of NCD and inform comprehensive interventions

Instituto Nacional de Infectologia Evandro Chagas. Rio de Janeiro, RJ, Brasil.Introdução: Estudos recentes realizados em Moçambique mostraram que a prevalência da coinfecção HIV/HTLV-I em pacientes adultos infetados pelo HIV é de 4.5% e que a mesma cursa com dissociação entre os parâmetros clínicos e imunológicos. No entanto, até a data, não existem dados sobre a prevalência e características clínico-laboratoriais da coinfecção HIV/HTLV-I na população pediátrica, em Moçambique. Objetivo: Determinar a seroprevalência e características clínico-laboratoriais da infeção por HTLV-1 em crianças moçambicanas seropositivas para o HIV atendidas em Unidades Sanitárias da Cidade de Maputo. Métodos: Entre Novembro de 2010 e Agosto de 2011, foram estudadas de forma consecutiva, 945 crianças infetadas pelo HIV, atendidas na consulta da criança em risco (CCR) em 3 Unidades Sanitárias da Cidade de Maputo, para o rastreio da infeção pelo HTLV-I, contagem de células T CD4+ e determinação dos parâmetros hematológicos. Cada criança com coinfecção HIV/HTLV-I foi pareada com duas crianças com monoinfeção por HIV de acordo com a idade, o sexo e estadiamento clínico do HIV (OMS) para comparação de parâmetros clínicos e epidemiológicos. Resultados: Foram recrutadas para o estudo 945 crianças, das quais 37 (3,9%; IC: 2.8 - 5.4%) foram positivas para o HTLV-I. A mediana da idade foi de 6 anos [Intervalo Interquartil (IQR): 4 - 9]. Não houve diferença significativa entre crianças mono e co-infectadas em relação à idade, sexo, parâmetros hematológicos, estadiamento da infecção pelo HIV e uso de antirretrovirais. Na análise dos casos pareados não foram observadas diferenças significativas entre os dois grupos relacionadas a dados epidemiológicos e clínicos. Nenhuma das crianças coinfectadas tinha manifestações clínicas do HTLV-I e apenas 4/37 apresentaram carga próviral detectável. Discussão: Nossos dados demonstram que a infecção pelo HTLV-I circula também em crianças infectadas pelo HIV em Moçambique e que a contagem de células CD4 em sangue periférico não foi alterada na coinfecção na população estudada. Estes resultados são importantes para o desenho e implementação de novas estratégias para prevenção da transmissão vertical do HTLV-I, bem como para o manuseio clínico das crianças infetadas pelo HTLV-I em Moçambique

Tuberculosis in Mozambique: Where Do We Stand?

Purpose of Review: Tuberculosis (TB) is a global health concern, and Mozambique is one of the few high burden tuberculosis countries where the estimated TB incidence has not improved in recent years. The objective of this review is to provide a snapshot of the current situation of the TB epidemic in Mozambique, highlighting the main epidemiological features and particularities of TB care and control in the country. Recent Findings: Despite several efforts aimed at improving diagnosis and treatment success, the overall burden of TB, HIV-TB, and multidrug-resistant (MDR)-TB is enormous, with high TB-associated mortality. Improving surveillance is a key step for understanding the TB epidemic in the country, and the first TB prevalence survey is underway. Overall, drug-sensitive and MDR-TB notifications have increased markedly over the last 5 years, likely due in part to a more active case finding approaches, but the diagnosis gap is still substantial. The roll-out of Xpert technology to decentralized settings is improving TB diagnosis in the country, particularly for MDR-TB. Summary: Although some progress has been made in TB control in Mozambique, the challenges for TB control and elimination are enormous. More actively finding cases at health facilities and in communities via contact tracing, improving national surveillance/monitoring and evaluation systems, expanding TB molecular diagnosis, implementing shorter MDR-TB treatments, and improving HIV-TB case management (including rigorous TB screening and higher coverage of preventive therapies in people living with HIV) are considered key priorities for the National TB Control Program

Barriers to access and adherence to tuberculosis services, as perceived by patients: A qualitative study in Mozambique.

IntroductionTuberculosis (TB) continues to be a leading cause of death in Sub-Saharan Africa, including Mozambique. While diagnostic methods and total notifications are improving, significant gaps remain between total numbers of TB cases annually, and the number that are notified. The purpose of this study was to elicit Mozambican patients with drug sensitive TB (DS-TB), TB/HIV and Multi drug resistant tuberculosis (MDR-TB) understanding and assessment of the quality of care for DS-TB, HIV/TB and MDR-TB services in Mozambique, along with challenges to effectively preventing, diagnosing and treating TB.Materials and methodsQualitative data was collected via separate focus group discussions consisting of patients with DS-TB, TB/HIV and MDR-TB at four health centers in Sofala and Manica Province, Mozambique, to describe knowledge on TB, HIV and MDR-TB, and identify barriers to access and adherence to services and their recommendations for improvement. A total of 51 patients participated in 11 discussions. Content analysis was done and main themes were identified.ResultsFocus groups shared a number of prominent themes. Respondents identified numerous challenges including delays in diagnosis, stigma related with diagnosis and treatment, long waits at health facilities, the absence of nutritional support for patients with TB, the absence of a comprehensive psychosocial support program, and the lack of overall knowledge about TB or multi drug resistant TB in the community.DiscussionTB patients in central Mozambique identified many challenges to effectively preventing, diagnosing and treating tuberculosis. Awareness strengthening in the community, continuous quality monitoring and in-service training is needed to increase screening, diagnosis and treatment for TB, HIV/TB and MDR-TB

Usability of simplified audiometry and electrocardiogram during treatment of drug-resistant tuberculosis in Mozambique: a qualitative study

Abstract Background In 2021, there were approximately 450,000 cases of drug-resistant tuberculosis (DR-TB) worldwide. The treatment of DR-TB historically included expensive and toxic injectable drugs leading to adverse effects including ototoxicity and Electrocardiogram (ECG) abnormalities. This study described the perspectives of healthcare providers and people with DR-TB on the usability of simplified audiometry and ECG for monitoring treatment adverse effects. Methods A qualitative study was conducted in December 2019 across four provinces in Mozambique, namely Maputo, Gaza, Zambézia, and Nampula. Sixteen outpatient primary care health facilities equipped with simplified Audiometry and/or ECG devices (specifically, SHOEBOX Audiometer® and/or SmartHeart Pro ECG®) installed for at least 6 months before the study initiation were selected. The data was collected using in-depth interviews (IDI) and Focus Group Discussions (FGD) techniques. Interviews were audio-recorded, transcribed verbatim in Portuguese, coded, and analyzed using Nvivo 12 software®. We generated two themes and fit our results into a conceptual framework consisting of three domains in the implementation of technological innovations in health. Results A total of 16 healthcare providers and 91 people undergoing treatment for DR-TB were enrolled in the study. Most people with DR-TB had experienced audiometry testing and demonstrated a good understanding of the assessments. Conversely, while most healthcare providers demonstrated robust knowledge of the importance of both audiometry and ECG assessments, they were not confident in managing ECG devices and interpreting the results. Conclusions While healthcare providers demonstrated a consolidated understanding of the importance of audiometry, the limited number of devices and lack of training were constraints, impeding optimal usage and service delivery
