The Medical Education Partnership Initiative Effect on Increasing Health Professions Education and Research Capacity in Mozambique
Background: Mozambique is an emerging lower income country (LIC) on the southeast coast of Africa. There are significant workforce shortages in medical and health professions in the country. Mozambique was one of 12 countries in Africa that was awarded a grant through the Medical Education Partnership Initiative (MEPI) in 2010. The overarching goal of MEPI Mozambique was to enhance the capacity of medical schools to train the medical and scientific leadership corps that the country required to facilitate the training of doctors and other health professionals, and thus to strengthen the national health system. Objective: The aim of this article is to provide an overview of MEPI Mozambique activities, its outcomes and successes, lessons learned, and how these have sustainably strengthened the health sector in the country. What Was Done: The Eduardo Mondlane University (UEM) formed a partnership with the University of California, San Diego (UCSD) to implement MEPI Mozambique. A range of activities in medical education, research capacity development, electronic connectivity and information technology, and developing relationships among medical education stakeholders, were performed. Outcomes and Effects: The activities and innovations introduced under MEPI became part of the daily routine in medical education in Mozambique, dramatically influencing attitudes and perceptions. Joint research with partners leveraged research capabilities. The creation of a research support center offered a mechanism to sustainably build on MEPI achievements. Scientific knowledge generated through research has been translated into practice and policy, and has improved the working environment for health professionals. The use of interactive communication technologies enabled the scaling up of training and research in sustainable ways, and created communities of practice. Conclusion: MEPI Mozambique developed transformational long-term partnerships between UEM, UCSD and other partners. These are changing the trajectory of medical and health professions education in Mozambique and creating sustainable capacity for research
Comparative Study of rK39 Leishmania Antigen for Serodiagnosis of Visceral Leishmaniasis: Systematic Review with Meta-Analysis
Visceral Leishmaniasis (VL) is a neglected tropical disease for which serodiagnostic tests are available, but not yet widely implemented in rural areas. The rK39 recombinant protein is derived from a kinesin-like protein of parasites belonging to the Leishmania donovani complex, and has been used in the last two decades for the serodiagnosis of VL. We present here a systematic review and meta-analysis of studies evaluating serologic assays (rK39 strip-test, rK39 ELISA, Direct Agglutination Test [DAT], Indirect Immunofluorescence test [IFAT] and ELISA with a promastigote antigen preparation [p-ELISA]) to diagnose VL to determine the accuracy of rK39 antigen in comparison to the use of other antigen preparations. Fourteen papers fulfilled the inclusion and exclusion selection criteria. The summarized sensitivity for the rK39-ELISA was 92% followed by IFAT 88% and p-ELISA 87%. The summarized specificity for the three diagnostic tests was 81%, 90%, and 77%. Studies comparing the rK39 strip test with DAT found a similar sensitivity (94%) and specificity (89%). However, the rK39 strip test was more specific than the IFAT and p-ELISA. In conclusion, we found the rK39 protein used either in a strip test or in an ELISA is a good choice for the serodiagnosis of VL
A randomized clinical trial to evaluate the efficacy of L-carnitine L-tartrate to modulate the effects of SARS-CoV-2 infection
IntroductionL-carnitine (LC) has been associated with inflammatory mediator reduction and with downregulating the angiotensin-converting enzyme-2 (ACE2) receptor, which is the target of SARS-CoV-2 attachment.MethodsThis pilot phase 2 randomized, double-blind placebo-controlled trial contained two cohorts. Cohort 1 comprised 101 individuals with negative RT-PCR SARS-CoV-2 test results who cohabitated with an individual diagnosed with SARS-CoV-2 infection. Cohort 2 comprised 122 individuals with positive SARS-CoV-2 RT-PCR test results who were asymptomatic or had mild COVID-19 pneumonia symptoms. Participants in each cohort were randomized 1:1 to receive either 2 g elemental oral LC supplementation or placebo daily for 21 days. Primary endpoints included adverse events, SARS-CoV-2 infection incidence in Cohort 1, and disease progressions in Cohort 2. Secondary endpoints included between-group laboratory profile comparisons and Cohort 2 ACE1/ACE2 plasma levels. Disease progression was compared between the Cohort 2 groups using chest computed tomography.ResultsIn Cohort 1, two SARS-CoV-2 infections occurred in each group. The common adverse events included headache, dyspnea, and tiredness. In Cohort 2, platelet counts were elevated, and fibrinogen levels reduced in the LC group compared with those of the placebo group.ConclusionOur study showed that LC was well-tolerated and suggests it modulates coagulation pathways. Furthermore, chest computed tomography images of the Cohort 2 LC group showed significant lung lesion improvement, suggesting that LC may slow COVID-19 progression
Successful use of a defined antigen/GM-CSF adjuvant vaccine to treat mucosal leishmaniasis refractory to antimony: a case report
Immunotherapy has been proposed as a method to treat mucosal leishmaniasis for many years, but the approach has been hampered by poor definition and variability of antigens used, and results have been inconclusive. We report here a case of antimonial-refractory mucosal leishmaniasis in a 45 year old male who was treated with three single injections (one per month) with a cocktail of four Leishmania recombinant antigens selected after documented hypo-responsiveness of the patient to these antigens, plus 50mg of GM-CSF as vaccine adjuvant. Three months after treatment, all lesions had resolved completely and the patient remains without relapse after two years. Side effects of the treatment included only moderate erythema and induration at the injection site after the second and third injections. We conclude that carefully selected microbial antigens and cytokine adjuvant can be successful as immunotherapy for patients with antimonial-refractory mucosal leishmaniasis
A cross-sectional study of sub-clinical <it>Plasmodium falciparum</it> infection in HIV-1 infected and uninfected populations in Mozambique, South-Eastern Africa
<p>Abstract</p> <p>Background</p> <p><it>Plasmodium falciparum</it> and HIV-1 infection cause substantial morbidity and mortality in sub-Saharan Africa. Increasing evidence suggests these two pathogens interact negatively when infecting the same individual.</p> <p>Methods</p> <p>A cross-sectional study among HIV-1 infected and uninfected populations was recruited in Mocuba and Maputo, Mozambique to determine the prevalence of sub-clinical malarial parasitaemia using light microscopy and a nested PCR assay.</p> <p>Results</p> <p>The prevalence of sub-clinical <it>P. falciparum</it> parasitaemia was low in Maputo, whether determined by microscopy (0.4%) or PCR (1.9%), but substantially higher in Mocuba (7.6 and 14.7%, respectively). Nested PCR detected nearly 70% more cases of sub-clinical parasitaemia than microscopy, but differences occur by locality. HIV-1 infected persons were more likely to be sub-clinically parasitaemic than HIV-1 uninfected individuals recruited from the same geographic areas. Trimethoprim-sulphamethoxazole use did not substantially reduce sub-clinical parasitaemia.</p> <p>Conclusions</p> <p>Dried blood spots are a convenient and sensitive technique for detecting sub-clinical infection with <it>P. falciparum</it> by nested PCR<it>.</it> Prevalence of <it>P. falciparum</it> is substantially lower in Maputo where malaria control programmes have been more active than in the rural town of Mocuba. In Mocuba, among those presenting for HIV-1 counseling and testing, the prevalence of <it>P. falciparum</it> is substantially higher in those who test positive for HIV-1 than those without HIV-1 infection. The clinical implications of sub-clinical <it>P. falciparum</it> infection among HIV-1 infected persons warrant additional study<b>.</b></p
