gaps in knowledge and research opportunities

Toxoplasmosis is a parasitic zoonotic disease caused by Toxoplasma gondii that afflicts humans worldwide and wild and domestic warm-blooded animals. In immunocompetent individuals, the acute phase of infection presents transient low or mild symptoms that remain unnoticed. In immunocompromised patients, T. gondii is a life-threatening opportunistic infection, which can result from the reactivation of latent infection or primary infection. Moreover, congenital toxoplasmosis, which results from the transplacental passage of tachyzoites into the fetus during a pregnant primary infection, can lead to miscarriage, stillbirth, or ocular and neurologic disease, and neurocognitive deficits in the newborns. Thus, the present review aims to address the current knowledge of T. gondii infection and toxoplasmosis in Africa and especially in Mozambique, stressing the importance of identifying risk factors and promote awareness among the health care providers and population, assessing the gaps in knowledge and define research priorities. In Mozambique, and in general in southern African countries, clinical disease and epidemiological data have not yet been entirely addressed in addition to the implications of T. gondii infection in immunocompetent individuals, in pregnant women, and its relation with neuropsychiatric disorders. The main gaps in knowledge in Mozambique include lack of awareness of the disease, lack of diagnostic methods in health facilities, lack of genetic data, and lack of control strategies.[Figure not available: see fulltext.]publishersversionpublishe

The Evolution of Mentorship Capacity Development in Low- and Middle-Income Countries: Case Studies from Peru, Kenya, India, and Mozambique.

Following the Fogarty International Center-supported "Mentoring the Mentors" workshops in South America, Africa, and Asia, approaches and guidelines for mentorship at institutions within these low- and middle-income country (LMIC) contexts, appropriate for the respective regional resources and culture, were implemented. Through the presentation of case studies from these three geographic regions, this article illustrates the institutional mentorship infrastructure before the workshop and the identified gaps used to implement strategies to build mentorship capacity at the Universidad Peruana Cayetano Heredia (Peru), Kenya Medical Research Institute (Kenya), Saint John's Research Institute (India), and Eduardo Mondlane University (Mozambique). These case studies illustrate three findings: first, that mentorship programs in LMICs have made uneven progress, and institutions with existing programs have exhibited greater advancement to their mentoring capacity than institutions without formal programs before the workshops. Second, mentoring needs assessments help garner the support of institutional leadership and create local ownership. Third, developing a culture of mentorship that includes group mentoring activities at LMIC institutions can help overcome the shortage of trained mentors. Regardless of the stage of mentoring programs, LMIC institutions can work toward developing sustainable, culturally effective mentorship models that further the partnership of early career scientists and global health

A Cross-sectional Serological Study of Cysticercosis, Schistosomiasis, Toxocariasis and Echinococcosis in HIV-1 Infected People in Beira, Mozambique

Background: Helminthic infections are highly endemic in Mozambique, due to limited access to healthcare and resources for disease prevention. Data on the subclinical prevalence of these diseases are scarce due to the fact that an immunological and imaging diagnosis is not often available in endemic areas. We conducted a cross-sectional study on HIV1+ patients from Beira city in order to determine the seroprevalence of cysticercosis, schistosomiasis, toxocariasis and echinoccocosis and its possible interaction with HIV infection. Methodology/Principal Findings: Patients (601) were voluntarily recruited at the Ponta Gea Health Center and their demographic and clinical data were recorded (including CD4+ cell count and antiretroviral regimen). Mean age was 39.7 years, 378 (62.9%) were women and 223 (37.1%) were men. Four hundred seventy-five (475) patients (79%) were already on highly active antiretroviral therapy (HAART), and 90 started therapy after being enrolled in the study. For serological testing we used a Multiplex Western Blot IgG from LDBIO Diagnostics. The overall seroprevalence was 10.2% for cysticercosis, 23% for schistosomiasis, 7.3% for toxocariasis and 17.3% for echinococcosis. Conclusions/Significance: Neither age nor the CD4+ count were significantly associated with the seroprevalence of the helminths studied. However, patients with CD4+ between 200–500/µl had a higher seroprevalence to all helminths than those with less than 200/µl cells/and those with more than 500 cells/µl. Female gender was significantly associated with cysticercosis and schistosomiasis, and being in HAART with toxocariasis. Headache was significantly associated with cysticercosis and toxocariasis. There was no association between epilepsy and seropositivity to any of the parasites. The study concluded that a clear understanding of the prevalence and manifestations of these coinfections, how best to diagnose subclinical cases, and how to manage diseases with concomitant antiretroviral therapy is needed.The study was funded by the US National Institutes of Health through an International Pilot Grant from the UCSD Center for AIDS Research ((http://cfar.ucsd.edu/), grant number NIAID 5 P30 AI 036214.

VIH E Cancro Do Esófago Em Moçambique: O Que É Que Aprendemos?

Esophageal cancer (EC) is a common cancer in Mozambique, with esophageal squamous cell carcinomas (ESCC) being the most frequent subtype of this cancer. Little is known about the impact of the human immunodeficiency virus (HIV) on this pathology. The main goal of this study was to assess the association between EC and HIV infection. Methods: A case-control study was conducted, in 2018, at Maputo Central Hospital, Mozambique (MCH).  Consenting adults were eligible for inclusion. Patients with ESCC who underwent HIV testing constituted the case groups. Controls were selected from patients with surgical benign conditions, and they were matched by sex and age. Chi-square or Fisher’s exact tests were used to evaluate the association between two categorical variables. Comparisons between groups were performed, using independent samples t-tests or Mann–Whitney tests for continuous variables. Odds Ratio (OR), and the corresponding 95% confidence interval (CI) were computed using non-conditional logistic regression. A p-value < 0.05 was considered significant. Results: During the study period, 92 cases and 92 controls were enrolled into the study. 67.4% of the cases were female. The median age of cases and controls was 57 (35-83) and 52 (35-85) years, respectively. HIV-positive diagnosis significantly increased the odds of developing EC, mainly in females (OR=4.81; 95% CI: 2.24–10.32; p<0.001), but the same did not occur in males (OR=2.26; 95% CI: 0.80–6.36; p=0.123). Conclusion: Esophageal cancer and human immunodeficiency virus are common in Mozambique.  HIV infection is a potential risk factor for ESCC mainly in the female gender. Patients with HIV and other risk factors such as exposure to domestic or tobacco smoke should be educated and followed up for an early diagnosis of esophageal cancer. O cancro do esófago (CE) é um cancro comum em Moçambique, sendo os carcinomas de células escamosas do esófago (CCEE) o subtipo mais frequente deste cancro. Pouco se sabe sobre o impacto do vírus da imunodeficiência humana (VIH) nesta patologia. O principal objetivo deste estudo foi avaliar a associação entre CE e infeção pelo VIH. Métodos: Um estudo de caso-controlo foi conduzido, em 2018, no Hospital Central de Maputo, Moçambique (HCM). Adultos que consentiram em participar foram considerados elegíveis. Doentes com CCEE que realizaram teste de VIH constituíram o grupo de casos. Os controlos foram selecionados entre os doentes com condições benignas cirúrgicas que seriam operados no HCM, tendo sido emparelhados por sexo e idade. Os testes de qui-quadrado ou exato de Fisher foram utilizados para avaliar potenciais associações entre duas variáveis categóricas. Para realizar comparações entre grupos foi utilizado o teste t para amostras independentes ou o teste de Mann-Whitney para as variáveis contínuas. A razão de chances (OR) e o respetivo intervalo de confiança de 95% (IC) foram calculados usando regressão logística não-condicional. Um valor de p < 0,05 foi considerado significativo. Resultados: Durante o período de estudo, 92 casos e 92 controlos foram incluídos no estudo. 67,4% dos casos eram do sexo feminino. A idade mediana dos casos e dos controlos foi de 57 (35-83) e 52 (35-85) anos, respetivamente. O diagnóstico de VIH positivo aumentou significativamente as chances de desenvolver CE, principalmente nas mulheres (OR=4,81; IC 95%: 2,24–10,32; p<0,001), mas o mesmo não ocorreu nos homens (OR=2,26; IC 95%: 0,80–6,36; p=0,123). Conclusão: O cancro do esófago e o vírus da imunodeficiência humana são comuns em Moçambique. A infeção por VIH é um potencial fator de risco para CCEE, principalmente no sexo feminino. Pacientes com VIH e outros fatores de risco, como a exposição ao fumo doméstico ou do tabaco, devem ser educados e acompanhados para um diagnóstico precoce do cancro do esófago

A prospective observational study of bacteraemia in adults admitted to an urban Mozambican hospital

Background. Bacteraemia is a common cause of fever among patients presenting to hospitals in sub-Saharan Africa. The worldwide rise of antibiotic resistance makes empirical therapy increasingly difficult, especially in resource-limited settings.Objectives. To describe the incidence of bacteraemia in febrile adults presenting to Maputo Central Hospital (MCH), an urban referral hospital in the capital of Mozambique, and characterise the causative organisms and antibiotic susceptibilities. We aimed to describe the antibiotic prescribing habits of local doctors, to identify areas for quality improvement. Methods. Inclusion criteria were: (i) ≥18 years of age; (ii) axillary temperature ≥38°C or ≤35°C; (iii) admission to MCH medical wards in the past 24 hours; and (iv) no receipt of antibiotics as an inpatient. Blood cultures were drawn from enrolled patients and incubated using the BacT/Alert automated system (bioMérieux, France). Antibiotic susceptibilities were tested using the Kirby-Bauer disc diffusion method. Results. Of the 841 patients enrolled, 63 (7.5%) had a bloodstream infection. The most common isolates were Staphylococcus aureus, Escherichia coli, and non-typhoidal Salmonella. Antibiotic resistance was common, with 20/59 (33.9%) of all bacterial isolates showing resistance to ceftriaxone, the broadest-spectrum antibiotic commonly available at MCH. Receipt of insufficiently broad empirical antibiotics was associated with poor in-hospital outcomes (odds ratio 8.05; 95% confidence interval 1.62 - 39.91; p=0.04). Conclusion. This study highlights several opportunities for quality improvement, including educating doctors to have a higher index of suspicion for bacteraemia, improving local antibiotic guidelines, improving communication between laboratory and doctors, and increasing the supply of some key antibiotics.

Strengthening research capacity through the medical education partnership initiative: the Mozambique experience

BACKGROUND: Since Mozambique’s independence, the major emphasis of its higher educational institutions has been on didactic education. Because of fiscal and human resource constraints, basic and applied research activities have been relatively modest in scope, and priorities have often been set primarily by external collaborators. These factors have compromised the scope and the relevance of locally conducted research and have limited the impact of Mozambique’s universities as major catalysts for national development. CASE DESCRIPTION: We developed a multi-institutional partnership to undertake a comprehensive analysis of the research environment at Mozambique’s major public universities to identify factors that have served as barriers to the development of a robust research enterprise. Based on this analysis, we developed a multifaceted plan to reduce the impact of these barriers and to enhance research capacity within Mozambique. INTERVENTIONS: On the basis of our needs assessment, we have implemented a number of major initiatives within participating institutions to facilitate basic and applied research activities. These have included specialized training programmes, a reorganization of the research administration infrastructure, the development of multiple collaborative research projects that have emphasized local research priorities and a substantial investment in bioinformatics. We have established a research support centre that provides grant development and management services to Mozambique’s public universities and have developed an independent Institutional Review Board for the review of research involving human research subjects. Multiple research projects involving both communicable and non-communicable diseases have been developed and substantial external research support has been obtained to undertake these projects. A sizable investment in biomedical informatics has enhanced both connectivity and access to digital reference material. Active engagement with relevant entities within the Government of Mozambique has aligned institutional development with national priorities. CONCLUSIONS: Although multiple challenges remain, over the past 3 years significant progress has been made towards establishing conditions within which a broad range of basic, translational and clinical and public health research can be undertaken. Ongoing development of this research enterprise will enhance capacity to address critical locally relevant research questions and will leverage resources to accelerate the development of Mozambique’s national universities

From easing lockdowns to scaling up community-based coronavirus disease 2019 screening, testing, and contact tracing in Africa-shared approaches, innovations, and challenges to minimize morbidity and mortality

CITATION: Nachega, J. B. et al. 2021. From easing lockdowns to scaling up community-based coronavirus disease 2019 screening, testing, and contact tracing in Africa-shared approaches, innovations, and challenges to minimize morbidity and mortality. Clinical infectious diseases, 72(2):327–331. doi:10.1093/cid/ciaa695The original publication is available at https://academic.oup.com/cid/The arrival of coronavirus disease 2019 (COVID-19) on the African continent resulted in a range of lockdown measures that curtailed the spread of the infection but caused economic hardship. African countries now face difficult choices regarding easing of lockdowns and sustaining effective public health control measures and surveillance. Pandemic control will require efficient community screening, testing, and contact tracing; behavioral change interventions; adequate resources; and well-supported, community-based teams of trained, protected personnel. We discuss COVID-19 control approaches in selected African countries and the need for shared, affordable, innovative methods to overcome challenges and minimize mortality. This crisis presents a unique opportunity to align COVID-19 services with those already in place for human immunodeficiency virus, tuberculosis, malaria, and non communicable diseases through mobilization of Africa's interprofessional healthcare workforce. By addressing the challenges, the detrimental effect of the COVID-19 pandemic on African citizens can be minimized.https://academic.oup.com/cid/article/72/2/327/5849218?login=truePublishers versio

The critical need for pooled data on coronavirus disease 2019 in African children : an AFREhealth call for action through multicountry research collaboration

Globally, there are prevailing knowledge gaps in the epidemiology, clinical manifestations, and outcomes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among children and adolescents; and these gaps are especially wide in African countries. The availability of robust age-disaggregated data is a critical first step in improving knowledge on disease burden and manifestations of coronavirus disease 2019 (COVID-19) among children. Furthermore, it is essential to improve understanding of SARS-CoV-2 interactions with comorbidities and coinfections such as human immunodeficiency virus (HIV), tuberculosis, malaria, sickle cell disease, and malnutrition, which are highly prevalent among children in sub-Saharan Africa. The African Forum for Research and Education in Health (AFREhealth) COVID-19 Research Collaboration on Children and Adolescents is conducting studies across Western, Central, Eastern, and Southern Africa to address existing knowledge gaps. This consortium is expected to generate key evidence to inform clinical practice and public health policy-making for COVID-19 while concurrently addressing other major diseases affecting children in African countries.The US National Institutes of Health (NIH)/ Fogarty International Centre (FIC) to the African Forum for Research and Education in Health (AFREhealth).https://academic.oup.com/cidam2022Paediatrics and Child Healt
