The scope of this PPC document is to serve as a guide to address the unmet public health need for a PPE system that protects the HW-F in tropical climate
s while caring for patients and providing heavy duty essential health services.
The characteristics described in this guidance are targeted fo...r PPE used in
health clinics, hospitals and communities in low resource settings where there is lack of advanced environmental controls and equipment. The purpose is to ensure harmonization in PPE design and its use to avoid confusion and exacerbating the risk of infections in HW-F. The principles of this PPC document can also be considered in risk reduction strategies
in other healthcare settings.

The leishmaniases are a group of diseases caused by Leishmania spp., which occur in cutaneous, mucocutaneous and visceral forms. They are neglected tropical diseases (NTDs), which disproportionately affect marginalized populations who have limited access to health care. HIV co-infected patients with... Leishmania infection are highly infectious to sandflies, and an increase in the coinfection rate in an endemic area is likely to increase the effective infective reservoir.

In January 2021, the World Health Organization (WHO) published a new road map to address the burden of disease and death imposed by neglected tropical diseases (NTDs). The end of the first year of the 2021-2030 NTD road map is an opportunity to take stock of where we stand and how we plan to move fo...rward.
Considerable progress has been made since 2012 when the first road map was adopted. As of 6 June 2022, forty-six countries have eliminated at least one NTD, while 600 million people no longer require treatment because they are no longer exposed to risks associated with the pathogens that previously harmed them. In some cases, diseases that have plagued humanity for centuries, such as sleeping sickness and Guinea worm disease, are at an all-time low. Less tangible, but also important, there has been significant progress in the way NTDs are viewed. Additionally, the disruptive impact of the COVID-19 pandemic on NTD programmes is evident.
This brochure is the first in a series of advocacy briefs for the new NTD road map presenting highlights of success and challenges towards attaining the 2030 goals.

The Indigenous tribe called the Wiwa lives retracted in the Sierra Nevada de Santa Marta, Colombia. Little is known about their health status and whether the health care system in place covers their needs.
Abstract: Chagas disease is caused by infection with the protozoan Trypanosoma cruzi, and although over 100 years have passed since the discovery of Chagas disease, it still presents an increasing problem for global public health. A plethora of information concerning the chronic phase of human Chaga...s disease, particularly the severe cardiac form, is available in the literature. However, information concerning events during the acute phase of the disease is scarce. In this review, we will discuss the current status of acute Chagas disease cases globally, the immunological findings related to the acute phase and their possible influence in disease outcome, and reactivation of Chagas disease in immunocompromised individuals, a key point for transplantation and HIV invection management.

In 2005, the World Health Organization (WHO) recognized Chagas disease (CD; Trypanosoma cruzi infection) as a neglected tropical disease (NTD) [1] and included it into the global plan to combat NTDs [2]. The Target 3.3 of the United Nations Sustainable Development Goals (UN/SDG) aims at ending the e...pidemics of NTDs by 2030 [3]. Mother-to-child (congenital/connatal) transmission is currently the main mode of transmission of T. cruzi over blood transfusions and organ transplantations in vector-free areas within and outside Latin America (LA). Based on recent demonstrations that congenital transmission can be prevented [4–7], WHO has shifted its objective, in 2018, from control to elimination of congenital CD (cCD).

This was a Phase 3, multi-center, randomized, open-label, parallel-group, active control study where 273 male and female patients with first stage Trypanosoma brucei gambiense HAT were treated at six sites: one trypanosomiasis reference center in Angola, one hospital in South Sudan, and four hospita...ls in the Democratic Republic of the Congo between August 2005 and September 2009 to support the registration of pafuramidine for treatment of first stage HAT in collaboration with the United States Food and Drug Administration. Patients were treated with either 100 mg of pafuramidine orally twice a day for 10 days or 4 mg/kg pentamidine intramuscularly once daily for 7 days to assess the efficacy and safety of pafuramidine versus pentamidine. Pregnant and lactating women as well as adolescents were included.

Sleeping sickness is controlled by case detection and treatment but this often only reaches less than 75% of the population. Vector control is capable of completely interrupting HAT transmission but is not used because of expense. We conducted a full scale field trial of a refined vector control tec...hnology. From preliminary trials we determined the number of insecticidal tiny targets required to control tsetse populations by more than 90%. We then carried out a full scale, 500 km2 field trial covering two HAT foci in Northern Uganda (overall target density 5.7/km2). In 12 months tsetse populations declined by more than 90%. A mathematical model suggested that a 72% reduction in tsetse population is required to stop transmission in those settings. The Ugandan census suggests population density in the HAT foci is approximately 500 per km2. The estimated cost for a single round of active case detection (excluding treatment), covering 80% of the population, is US$433,333 (WHO figures). One year of vector control organised within country, which can completely stop HAT transmission, would cost US$42,700. The case for adding this new method of vector control to case detection and treatment is strong. We outline how such a component could be organised.

Chagas disease (CD), caused by the parasite Trypanosoma cruzi, affects ~6–7 million people worldwide. Significant limitations still exist in our understanding of CD. Harnessing individual participant data (IPD) from studies could support more in-depth analyses to address the many outstanding resea...rch questions. This systematic review aims to describe the characteristics and treatment practices of clinical studies in CD and assess the breadth and availability of research data for the potential establishment of a data-sharing platform.

Despite a historical association with poor tolerability, a comprehensive review on safety of antileishmanial chemotherapies is lacking. We carried out an update of a previous systematic review of all published clinical trials in visceral leishmaniasis (VL) from 1980 to 2019 to document any reported ...serious adverse events (SAEs).

Mycetoma is a chronic infectious disease of the subcutaneous tissue with a high morbidity. This disease has been reported from countries between 30°N and 15°S since 1840 but the exact burden of disease is not known. It is currently unknown what the incidence, prevalence and the number of reported ...cases per year per country is. In order to estimate what the global burden of mycetoma is, a meta-analysis was performed. In total 50 studies were included, which resulted in a total of 8763 mycetoma cases. Most cases were found in men between 11 and 40 years of age. The foot was most commonly affected.

Yaws is targeted for eradication by 2030, using a strategy based on mass drug administration (MDA) with azithromycin. New diagnostics are needed to aid eradication. Serology is currently the mainstay for yaws diagnosis; however, inaccuracies associated with current serological tests makes it difficu...lt to fully assess the need for and impact of eradication campaigns using these tools. Under the recommendation of the WHO Diagnostic Technical Advisory Group (DTAG) for Neglected Tropical Diseases(NTDs), a working group was assembled and tasked with agreeing on priority use cases for developing target product profiles (TPPs) for new diagnostics tools.

Background
Low- and middle-income countries now experience the highest prevalence and mortality rates of cardiovascular disease.
Main text
While improving the availability and delivery of proven, effective therapies will no doubt mitigate this burden, we posit that studies evaluating cardiovasc...ular disease risk factors, management strategies and service delivery, in diverse settings and diverse populations, are equally critical to improving outcomes in low- and middle-income countries. Focusing on examples drawn from four cardiovascular diseases — coronary artery disease, stroke, diabetes and kidney disease — we argue that ethnicity, culture and context matter in determining the risk factors for disease as well as the comparative effectiveness of medications and other interventions, particularly diet and lifestyle interventions.
Conclusion
We believe that a host of cohort studies and randomized control trials currently being conducted or planned in low- and middle-income countries, focusing on previously understudied race/ethnic groups, have the potential to increase knowledge about the cause(s) and management of cardiovascular diseases across the world.
