Tanzania, like other developing countries, is facing a higher burden of cardiovascular diseases (CVDs). The country is experiencing rapid growth of modifiable and intermediate risk factors that accelerate CVD mortality and morbidity rates. In rural and urban settings, cardiovascular risk factors suc...h as tobacco use, excessive alcohol consumption, unhealthy diet, hypertension, diabetes, hyperlipidemia, overweight, and obesity, are documented to be higher in this review. Increased urbanization, lifestyle changes, lack of awareness and rural to urban movement have been found to increase CVD risk factors in Tanzania. Despite the identification of modifiable risk factors for CVDs, there is still limited information on physical inactivity and eating habits among Tanzanian population that needs to be addressed. Conclusively, primary prevention, improved healthcare system, which include affordable health services, availability of trained health care providers, improved screening and diagnostic equipment, adequate guidelines, and essential drugs for CVDs are the key actions that need to be implemented for cost effective control and management of CVDs. Effective policy for control and management of CVDs should also properly be employed to ensure fruitful implementation of different interventions.

Chagas heart disease (CHD) affects approximately 30% of patients chronically infected with the protozoa Trypanosoma cruzi. CHD is classified into four stages of increasing severity according to electrocardiographic, echocardiographic, and clinical criteria. CHD presents with a myriad of clinical man...ifestations, but its main complications are sudden cardiac death, heart failure, and stroke. Importantly, CHD has a higher incidence of sudden cardiac death and stroke than most other cardiopathies, and patients with CHD complicated by heart failure have a higher mortality than patients with heart failure caused by other etiologies. Among patients with CHD, approximately 90% of deaths can be attributed to complications of Chagas disease. Sudden cardiac death is the most common cause of death (55%-60%), followed by heart failure (25%-30%) and stroke (10%-15%). The high morbimortality and the unique characteristics of CHD demand an individualized approach according to the stage of the disease and associated complications the patient presents with. Therefore, the management of CHD is challenging, and in this review, we present the most updated available data to help clinicians and cardiologists in the care of these patients. We describe the clinical manifestations, diagnosis and classification criteria, risk stratification, and approach to the different clinical aspects of CHD using diagnostic tools and pharmacological and non-pharmacological treatments.

Leptospirosis is a perplexing conundrum for many. In the existing literature, the pathophysiological mechanisms pertaining to leptospirosis is still not understood in full. Considered as a neglected tropical zoonotic disease, leptospirosis is culminating as a serious problem worldwide, seemingly exi...sting as co-infections with various other unrelated diseases, including dengue and malaria. Misdiagnosis is also common as non-specific symptoms are documented extensively in the literature. This can easily lead to death, as the severe form of leptospirosis (Weil’s disease) manifests as a complex of systemic complications, especially renal failure. The virulence of Leptospira sp. is usually attributed to the outer membrane proteins, including LipL32. With an armament of virulence factors at their disposal, their ability to easily adhere, invade and replicate within cells calls for a swift refinement in research progress to establish their exact pathophysiological framework. As an effort to reconstitute the current knowledge on leptospirosis, the basis of leptospiral infection, including its risk factors, classification, morphology, transmission, pathogenesis, co-infections and clinical manifestations are highlighted in this review. The various diagnostic techniques are also outlined with emphasis on their respective pros and cons.

Le Plan Stratégique National de Lutte contre le Paludisme de la RDC vise à renforcer la communication pour le changement social et comportemental (CSC/CCC) dans la lutte contre le paludisme. Il a pour objectif d’améliorer les connaissances, attitudes et pratiques des populations pour encourager... l’adoption de comportements préventifs et curatifs.
Ce document propose une stratégie de communication structurée, basée sur une analyse contextuelle des comportements, croyances et obstacles sociaux. Il cible en priorité les femmes enceintes, les enfants de moins de cinq ans, les agents communautaires, les leaders religieux, les enseignants, et les médias. Les messages sont adaptés aux réalités locales et diffusés par des canaux variés : radios communautaires, théâtre, affiches, séances éducatives, et implication des leaders d'opinion.
Le plan insiste sur l’importance de la mobilisation sociale, de l’approche participative et du dialogue communautaire pour renforcer l’adhésion aux pratiques comme l’utilisation des moustiquaires imprégnées, le recours au test de diagnostic rapide, l’observance des traitements, et la fréquentation des centres de santé. Il prévoit aussi des mécanismes de suivi-évaluation et de renforcement des capacités des acteurs.
En résumé, ce document constitue un cadre opérationnel pour rendre la communication plus efficace, inclusive et durable dans la lutte contre le paludisme en RDC.

To meet the need for laboratory diagnosis to be integrated in community care, the new 2022 Update describes point-of-care tests that can be performed both in district laboratories and peripheral healthcare facilities by non-specialist staff. Also included are recently developed self-tests.
ASLM in collaboration with the Africa Centres for Disease Control and Prevention, and in partnership with the Clinton Health Access Initiative, Amref and Last Mile Health present the Quality Assurance Framework for SARS-CoV-2 Antigen Rapid Testing for Diagnosis of COVID-19. This framework aims to pr...ovide general technical guidance to African Union Members States on the rollout, establishment, implementation, monitoring, and evaluation of SARS-CoV-2 Ag RDT interventions so as to effectively and efficiently detect, control and minimise errors in the performance of COVID-19 laboratory testing processes. It describes the core components for quality assurance, resources mobilisation and advocacy for scale up, monitoring, evaluation, learning and accountability for SARS-CoV-2 implementation.

The purpose of this document is to provide guidance on the use of pooled sample testing strategy in coronavirus disease (COVID-19)
testing laboratories of the African Union Member States for scaling up SARS-CoV-2 nucleic acid testing capacity with the available resources. The current document descr...ibes the effect of factors such as the prevalence of COVID-19 in the population to be tested, the homogeneity of pools, and the sensitivity of the molecular test in optimal pool size determination. It also highlights the importance of monitoring the prevalence of COVID-19 in a population to be tested and proper validation of the test, to limit the potential for false-negative results. Validation studies to determine the optimal pool size by testing laboratories are recommended as the optimum approach. A safe, simple ‘two-stage pooling’ option has been indicated in this guidance to be used by laboratories until such validation can be achieved.
