The Institut Pasteur has created a MOOC entirely focused on Malaria, providing a glimpse of the wide range of disciplines involved and questions addressed in malaria research. It goes from basic cell and molecular biology of malaria parasites to field and hosp...ital based clinical research on malaria pathology. It covers the application of the latest genomic-based to investigate parasite biology to translational research on development of new control tools, including drugs and vaccines. It also deals with malaria epidemiology and clinical research, to better under-stand malaria as a public health
problem.

INTRODUCTION: Lower extremity peripheral artery disease (PAD) is increasing in prevalence in low- and middle-income countries creating a large health care burden. Clinical management may require substantial resources but little consideration has been given to which treatments are appropriate for les...s advantaged countries.
EVIDENCE ACQUISITION: The aim of this review was to systematically appraise published data on the costs and effectiveness of PAD treatments used commonly in high-income countries, and for an international consensus panel to review that information and propose a hierarchy of treatments relevant to low- and middle-income countries.
EVIDENCE SYNTHESIS: Pharmacotherapy for intermittent claudication was found to be expensive and improve walking distance by a modest amount. Exercise and endovascular therapies were more effective and exercise the most cost-effective. For critical limb ischemia, bypass surgery and endovascular therapy, which are both resource intensive, resulted in similar rates of amputation-free survival. Substantial reductions in cardiovascular events occurred with use of low cost drugs (statins, ACE inhibitors, anti-platelets) and smoking cessation.
CONCLUSIONS: The panel concluded that, in low- and middle-income countries, cardiovascular prevention is a top priority, whereas a lower priority should be given to pharmacotherapy for leg symptoms and revascularisation, except in countries with established vascular units.

The objective of the study was the validation and implementation of GeneXpert MTB/RIF for routine use in the rapid detection of tuberculosis and sensitivity to rifampicin in clinical samples; for this, 1592 respiratory samples were collected and analyzed in the laboratory of Instituto Nacional de In...vestigación en Salud Pública Guayaquil. The analysis of the results of GeneXpert in comparison with smear microscopy showed an initial sensitivity of 99.8% and specificity of 93.2%; The analysis of discrepancies using the results of the culture as a reference method showed that the GeneXpert results considered false negatives turned out to be true negatives, the same happens with the false positives that correspond to true positives. Recalculated the sensitivity and specificity of the GeneXpert was 99.8% and 100% correspondingly. The comparison with the drugs susceptibility test showed a sensitivity of 91.4% and a specificity of 95.5% for the GeneXpert MTB/RIF system. It is concluded that the implementation of the GeneXpert system allows solution to certain problems associated with the application of conventional diagnostic methodologies, decreasing the waiting times, and increasing the sensitivity and specificity in the diagnosis of drug-resistant tuberculosis, thus generating a valuable opportunity for early diagnosis.

The larval stage of the parasite Taenia solium can encyst in the central nervous system causing neurocysticercosis, which is the main cause of acquired epilepsy in the countries in which the parasite is endemic. Endemic areas are those with the presence (or likely presence) of the full life cycle of... Taenia solium. The parasite is most prevalent in poor and vulnerable communities in which pigs roam free, open defecation is practiced, basic sanitation is deficient, and health education is absent or limited. Several tools are available for the control of Taenia solium. Preventive chemotherapy for Taenia solium taeniasis, which is directed at the adult tapeworm, is one of them. Other tools focus on pig management, pig vaccination and treatment, sanitation and hygiene, and community education. Three potential drugs—niclosamide, praziquantel, and albendazole—have been considered for use for preventive chemotherapy in Taenia solium taeniasis control programs through mass drug administration or targeted chemotherapy. In this Guideline, we provide recommendations for preventive chemotherapy in Taenia solium-endemic areas using niclosamide, praziquantel, or albendazole, including at which dose and in which population groups.

A new formulation of praziquantel, arpraziquantel (arPZQ), has been developed for preschool-
aged children (PSAC) to fill the treatment gap for this age group in schistosomiasis control and
elimination program...s. There is now a priority to ensure that the drug reaches all at-risk PSAC
in endemic areas, including hard-to-reach areas and populations. This study aimed to deter-
mine schistosomiasis treatment-related contextual factors among fishermen and island popu-
lations in Homa Bay County, Kenya, and to identify a suitable platform to deliver arPZQ.

This chapter discusses the antibacterial treatment of leprosy infections. Antibiotic treatment is
a key component of leprosy treatment, as it is vital to prevent the progression of the infection.
Treatment with rifampin and other antibiotics is highly effective and cures 98% of patients with
the ...leprosy infection. Furthermore, the relapse rate is very low, at about 1% over 5–10 years.
There is little M. leprae drug resistance in leprosy and few reports of multi-drug resistance (1, 2, 3,
4, 5, 6, 7, 8). An antibiotic treatment may take months or years to produce clinical improvement,
especially in patients with an initial high bacterial index (BI).

Background
Chronic congestive heart failure is a common condition that, if untreated, markedly impairs the quality of life and is associated with a high risk of recurrent hospitalization and death.
Methods
This review is based on articles retrieved by a selective search in PubMed, as well as on r...elevant guidelines.
Results
Evidence-based treatment options are available only for congestive heart failure with a low ejection fraction. Pharmacotherapy is based on neurohumoral inhibition of the renin-angiotensin-aldosterone system and the adrenergic system. The prognosis of patients with this condition has been further improved recently through the introduction of combined angiotensin receptor antagonists and neprilysin inhibitors. Modern implantable devices are a further component of treatment. Implantable defibrillators and special pacemakers for cardiac resynchronization are well established; the utility of alternative devices (baroreflex modulation or cardiac contractility modulation) needs to be investigated in further studies. It was recently shown that the catheter-based treatment of secondary mitral regurgitation with a MitraClip improves the outcome of selected patients.
Conclusion
The treatment of chronic systolic heart failure as recommended in the relevant guidelines, with drugs and implanted devices if indicated, can significantly improve the clinical outcome.

The cardiovascular disease continuum begins with risk factors such as diabetes mellitus (DM), progresses to vasculopathy and myocardial dysfunction, and finally ends with cardiovascular death. Diabetes is associated with a 2- to 4-fold increased risk for heart failure (HF). Moreover, HF patients wit...h DM have a worse prognosis than those without DM. Diabetes can cause myocardial ischemia via micro- and macrovasculopathy and can directly exert deleterious effects on the myocardium. Hyperglycemia, hyperinsulinemia, and insulin resistance can cause alterations in vascular homeostasis. Then, reduced nitric oxide and increased reactive oxygen species levels favor inflammation leading to atherothrombotic progression and myocardial dysfunction. The classification, diagnosis, and treatment of HF for a patient with and without DM remain the same. Until now, drugs targeting neurohumoral and metabolic pathways improved mortality and morbidity in HF with reduced ejection fraction (HFrEF). Therefore, all HFrEF patients should receive guideline-directed medical therapy. By contrast, drugs modulating neurohumoral activity did not improve survival in HF with preserved ejection fraction (HFpEF) patients. Trials investigating whether sodium-glucose cotransporter-2 inhibitors are effective in HFpEF are on-going. This review will summarize the epidemiology, pathophysiology, and treatment of HF in diabetes.

These guidelines are based on the 3rd Edition of the WHO Guidelines (Published 2015) World Health Organization’s Guidelines for the treatment of malaria. Additional literature surveys have been undertaken. Factors that were considered in the choice of therapeutic options included effectiveness, sa...fety, and impact on malaria transmission and on the emergence and spread of antimalarial drug resistance. On-going surveillance is critical given the spread of artemisinin resistance in Southeast Asia, although not yet confirmed anywhere in Africa. The guidelines on the treatment of malaria in South Africa aim to facilitate effective, appropriate and timeous treatment of malaria, thereby reducing the burden of this disease in our communities. This is essential to further reduce the malaria case fatality rates currently recorded in South Africa, to decrease malaria transmission and to limit resistance to antimalarial drugs.

HIV infection, due to the immunosuppressant that leads, nowadays constitutes an aggravating factor of endemic tuberculosis. Tuberculosis remains a huge burden to human health, even in the early 21st century. The situation is deteriorating in many countries, particularly because of the synergy with t...he HIV epidemic and the emergence of multidrug-resistant (MDR) and extensively drug resistant (XDR) tuberculosis. The urgent development of new tools that can improve the diagnosis, prevention and/or treatment of tuberculosis and other major mycobacterium diseases depends largely on the progress of basic and applied research. Faced with this situation, there is an urgent need for effective strategies and actions to permanently solve the problem of this endemic disease whose impact is too negative on people’s lives.

Solidarity” is an international clinical trial to help find an effective treatment for COVID-19, launched by the World Health Organization and partners.
The Solidarity Trial will compare four treatment options against standard of care, to assess their relative effectiveness against COVID-19. By... enrolling patients in multiple countries, the Solidarity Trial aims to rapidly discover whether any of the drugs slow disease progression or improve survival. Other drugs can be added based on emerging evidence.
Until there is sufficient evidence, WHO cautions against physicians and medical associations recommending or administering these unproven treatments to patients with COVID-19 or people self-medicating with them. WHO is concerned by reports of individuals self-medicating with chloroquine and causing themselves serious harm.

Countries experiencing concentrated epidemics of HIV need the size of key populations (KPs) to guide the national response on HIV and AIDS. Conducting a robust method to estimate the size of KPs is quite challenging as most of them are hidden and do not want to disclose theiridentity due to stigma a...nd discrimination associated with their behaviour. KPs in Bangladesh include female sex workers (FSW), people who inject drugs (PWID), men who have sex with men (MSM) including transgender (TG)/Hijra and sex workers, and clients of sex workers in the country or abroad.

This study was aimed to ascertain the clinical profile and management of patients with ischemic heart disease (IHD) and/or peripheral artery disease (PAD). In this observational and cross-sectional study developed in 80 hospitals throughout Spain, consecutive adults with stable IHD and/or PAD were i...ncluded. A total of 1089 patients were analyzed, of whom 65.3% had only IHD, 17.8% PAD and 16.9% both. A total of 80.6% were taking only one antiplatelet agent, and 18.2% were on dual antiplatelet therapy (mainly aspirin/clopidogrel). Almost all patients were taking ≥1 lipid lowering drug, mainly moderate-to-high intensity statins. IHD patients took ezetimibe more commonly than PAD (43.9% vs. 12.9%; p < 0.001). There were more patients with IHD that achieved blood pressure targets compared to PAD (<140/90 mmHg: 67.9% vs. 43.0%; p < 0.001; <130/80 mmHg: 34.1% vs. 15.7%; p < 0.001), LDL-cholesterol (<70 mg/dL: 53.1% vs. 41.5%; p = 0.033; <55 mg/dL: 26.5% vs. 16.0%; p = 0.025), and diabetes (HbA1c < 7%, with SGLT2i/GLP1-RA: 21.7% vs. 8.8%; p = 0.032). Modifications of antihypertensive agents and lipid-lowering therapy were performed in 69.0% and 82.3% of patients, respectively, without significant differences between groups. The use of SGLT2i/GLP1-RA was low. In conclusion, cardiovascular risk factors control remains poor among patients with IHD, PAD, or both. A higher use of combined therapy is warranted.

The international community sits at the tipping pointof a post-‐antibiotic era, where common bacterial infections are no longer treatable with the antibiotic armamentarium that exists. In South Africa, t...he identification of the first case of pan-‐resistant Klebsiella pneumoniae(Brink et al, J Clin Microbiol. 2013;51(1):369-‐72) marks a watershed moment and highlights ourtip of the antibiotic resistance ‘iceberg’ in this country. Multi-‐drug resistant (MDR)-‐bacterial infections, predominantly in Gram-‐negative bacteria such as Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosaand Acinetobacter baumanniiare now commonplace in South African hospitals. Whilst a number of expensive new antibiotics for Gram-‐positive bacterial infections have been manufactured recently (some of which are licenced for usein South Africa), no new antibiotics active against Gram-‐negative infections are expected in the next 10-‐15years. Hence what we have now, needs conserving

This is an update (third edition) of the BACPR Standards & Core Components and represents current evidence-based best practice and a pragmatic overview of the structure and function of Cardiovascular Prevention and Rehabilitation Programmes (CPRPs) in the UK. The previously described seven standards... have now been reduced to six but without sacrificing any of the key elements and with a greater emphasis placed on measurable clinical outcomes, audit and certification. Similarly, the second edition provided an overview of seven core components felt to be essential for the delivery of quality prevention and rehabilitation, and this too has been reduced to six. The interplay between cardio-protective therapies and medical risk factors is almost impossible to disentangle for the vast majority of patients and even if specific drug therapies are deployed exclusively for risk factor modulation, the indirect effect will also be cardio-protective. Thus, these have been combined into a single core component – medical risk management.
