A century after its discovery, Chagas' disease still represents a major public health challenge in Latin America. Moreover, because of growing population movements, an increasing number of cases of imported Chagas' disease have now been detected in non-endemic areas, such as North America and some E...uropean countries. This parasitic zoonosis, caused by Trypanosoma cruzi, is transmitted to humans by infected Triatominae insects, or occasionally by non-vectorial mechanisms, such as blood transfusion, mother to fetus, or oral ingestion of materials contaminated with parasites. Following the acute phase of the infection, untreated individuals enter a chronic phase that is initially asymptomatic or clinically unapparent. Usually, a few decades later, 40-50% of patients develop progressive cardiomyopathy and/or motility disturbances of the oesophagus and colon. In the last decades several interventions targeting primary, secondary and tertiary prevention of Chagas' disease have been attempted. While control of both vectorial and blood transfusion transmission of T cruzi (primary prevention) has been successful in many regions of Latin America, early detection and aetiological treatment of asymptomatic subjects with Chagas' disease (secondary prevention) have been largely underutilised. At the same time, in patients with established chronic disease, several pharmacological and non-pharmacological interventions are currently available and have been increasingly used with the intention of preventing or delaying complications of the disease (tertiary prevention). In this review we discuss in detail each of these issues.

American cutaneous leishmaniasis (CL) is a severely understudied and neglected“disease of poverty” widespread throughout Peru. Transmission dynamics of CL are complex, requiring sandfly vectors and mammalian reservoir hosts to maintain the pathogen in a local environment whereby incidental hosts... (people) can become infected. We employed a One-Health approach to understand CL transmission in rapidly changing region of northern Peru. We describe the characteristics of 529 CL positive patients from four participating clinics. Using conditional logistic regression, we assessed risk factors of CL for residents of small urban areas through a matched case-control study with 63 patients who had visited one of the same clinics for CL (cases) or other medical reasons (controls). We later enrolled 343 households as part of a community based study occurring in 15 urban and rural areas of Soritor. We
found 256 positive humans (n= 914) as tested via the Montenegro Skin Test; we found 11 positive dogs (n = 236) via an immunofluorescence antibody test. Our results suggest that most- if not all- of CL transmission is occurring in rural areas and that urban women and urban children engage in many high risk activities typically attributed to men. We find evidence that prevalence of past infection is highest among rural residents and men. We believe dogs are unlikely Leishmania reservoirs in either rural or urban settings. It remains unknown if the high number of MST positive children in rural areas is a result of peridomestic or intradomestic transmission.

After 100 years of chemotherapy with impractical and toxic drugs, an oral cure for human African trypanosomiasis (HAT) is available: Fexinidazole. In this case, we review the history of drug discovery for HAT with special emphasis on the discovery, pre-clinical development, and operational challenge...s of the clinical trials of fexinidazole. The screening of the Drugs for Neglected Diseases initiative (DNDi) HAT-library by the Swiss TPH had singled out fexinidazole, originally developed by Hoechst (now Sanofi), as the most promising of a series of over 800 nitroimidazoles and related molecules. In cell culture, fexinidazole has an IC50 of around 1 µM against Trypanosoma brucei and is more than 100-fold less toxic to mammalian cells. In the mouse model, fexinidazole cures both the first, haemolymphatic, and the second, meningoencephalitic stage of the infection, the latter at 100 mg/kg twice daily for 5 days. In patients, the clinical trials managed by DNDi and supported by Swiss TPH mainly conducted in the Democratic Republic of the Congo demonstrated that oral fexinidazole is safe and effective for use against first- and early second-stage sleeping sickness. Based on the positive opinion issued by the European Medicines Agency in 2018, the WHO has released new interim guidelines for the treatment of HAT including fexinidazole as the new therapy for first-stage and non-severe second-stage sleeping sickness caused by Trypanosoma brucei gambiense (gHAT). This greatly facilitates the diagnosis and treatment algorithm for gHAT, increasing the attainable coverage and paving the way towards the envisaged goal of zero transmission by 2030.

Carlos Chagas discovered American trypanosomiasis, also named Chagas disease (CD) in his honor, just over a century ago. He described the clinical aspects of the disease, characterized by its etiological agent (Trypanosoma cruzi) and identified its insect vector. Initially, CD occurred only in Latin... America and was considered a silent and poorly visible disease. More recently, CD became a neglected worldwide disease with a high morbimortality rate and substantial social impact, emerging as a significant public health threat. In this context, it is crucial to better understand better the epidemiological scenarios of CD and its transmission dynamics, involving people infected and at risk of infection, diversity of the parasite, vector species, and T. cruzi reservoirs. Although efforts have been made by endemic and non-endemic countries to control, treat, and interrupt disease transmission, the cure or complete eradication of CD are still topics of great concern and require global attention. Considering the current scenario of CD, also affecting non-endemic places such as Canada, USA, Europe, Australia, and Japan, in this review we aim to describe the spread of CD cases worldwide since its discovery until it has become a global public health concern.

The world faces grave consequences from the lack of available mental health services and treatment. Mental illness impacts every country, culture and community, with the World Health Organization (WHO) stating that 10% of the global burden of disease is related to mental, neurological and substance ...use disorders. In low-and middle-income countries, more than 75% of people with mental disorders receive no treatment at all for their disorder. During 2020, as a result of the global pandemic, 93% of countries reported their mental health services were either halted or interrupted (WHO, 2020e). WHO reported a 25% increase in depression and anxiety alone during the pandemic. The Organisation for Economic Co-operation and Development estimates depression and anxiety cost the global economy US $1 trillion dollars a year. All nurses have a health care role in mental health and substance use. ICN strongly advocates for the investment of further education and professional development in this area in order to support individuals and communities achieve the highest attainable standard of health which includes
physical, mental and social wellbeing.

This brief advocacy document highlights the burden, risks and prevention of injuries and violence, which took the lives of 4.4 million people in 2019 and constitute 8% of all deaths. Among the injury-related causes of death include road traffic crashes, drowning, falls, burns, poisoning and violence... against oneself or others. For people age 5-29 years, three of the top five causes of death are injury-related, including road traffic injuries, homicide, and suicide. Injuries and violence are not evenly distributed across or within countries – some people are more vulnerable than others depending on the conditions in which they are born, grow, work, live and age; in general, being young, male and of low socioeconomic status all increase the risk of injury. This document, aimed at public health professionals; injury prevention researchers, practitioners and advocates; and donors, draws attention to specific strategies based on sound scientific evidence that are effective and cost-effective at preventing injuries and violence; it is critical that these strategies are more widely implemented.

The 2018 NDHS is a national sample survey that provides up-to-date information on demographic and health indicators. The sample was selected using a stratified, two-stage cluster design, with enumeration areas (EAs) as the sampling units for the first stage. The second stage was a complete listing o...f households carried out in each of the 1,400 selected EAs. The target groups were women age 15-49 and men age 15-59
in randomly selected households across Nigeria. A representative sample of approximately 42,000 households was selected for the survey. One-third of the households (14,000) were selected for malaria, anaemia, and genotype testing of children age 6-59 months. Also, in the subsample of households selected
for the men’s survey, one eligible woman in each household was randomly selected for additional questions regarding domestic violence. Specifically, information was collected on fertility levels, marriage, fertility preferences, awareness and use of family planning methods, child feeding practices, nutritional status of women and children, adult and childhood mortality, awareness and attitudes regarding
HIV/AIDS, and female genital mutilation. The survey also assessed the nutritional status (according to weight and height measurements) of women and children in these households. In addition to presenting national estimates, the report provides estimates of key indicators for both rural and urban areas, the country’s six geopolitical zones and 36 states, and the Federal Capital Territory (FCT).

The Covid-19 pandemic has so far infected more than 30 million people in the world, having major impact on global health with collateral damage. In Mozambique, a public state of emergency was declared at the end of March 2020. This has limited people's movements and reduced public services, leading ...to a decrease in the number of people accessing health care facilities. An implementation research project, The Alert Community for a Prepared Hospital, has been promoting access to maternal and child health care, in Natikiri, Nampula, for the last four years. Nampula has the second highest incidence of Covid-19. The purpose of this study is to assess the impact of Covid-19 pandemic Government restrictions on access to maternal and child healthcare services. We compared health centres in Nampula city with healthcare centres in our research catchment area. We wanted to see if our previous research interventions have led to a more resilient response from the community.
METHODS: Mixed-methods research, descriptive, cross-sectional, retrospective, using a review of patient visit documentation. We compared maternal and child health care unit statistical indicators from March-May 2019 to the same time-period in 2020. We tested for significant changes in access to maternal and child health services, using KrushKall Wallis, One-way Anova and mean and standard deviation tests. We compared interviews with health professionals, traditional birth attendants and patients in the two areas. We gathered data from a comparable city health centre and the main city referral hospital. The Marrere health centre and Marrere General Hospital were the two Alert Community for a Prepared Hospital intervention sites.
RESULTS: Comparing 2019 quantitative maternal health services access indicators with those from 2020, showed decreases in most important indicators: family planning visits and elective C-sections dropped 28%; first antenatal visit occurring in the first trimester dropped 26%; hospital deliveries dropped a statistically significant 4% (p = 0.046), while home deliveries rose 74%; children vaccinated down 20%.
CONCLUSION: Our results demonstrated the negative collateral effects of Covid-19 pandemic Government restrictions, on access to maternal and child healthcare services, and highlighted the need to improve the health information system in Mozambique.

In order to meet changing global population needs and consumer expectations, healthcare systems worldwide are under transformation and face restructuring. As systems adapt and shift their emphasis in response to the disparate requests for healthcare services, oppor-tunities emerge for nurses, especi...ally the APN, to meet these demands and unmet needs (Bryant-Lukosius et al. 2017; Carryer et al. 2018; Cassiani & Zug 2014; Cooper & Docherty 2018; Hill et al. 2017; Maier et al.2017). In 2002, the International Council of Nurses (ICN) pro-vided an official position on Advanced Practice Nursing (ICN 2008a). Since that time, worldwide development has increased significantly and simultaneously this field of nursing has matured. ICN felt that a review of its position was needed to assess the relevance of the definition and characteristics offered in 2002. This guid-ance paper defines diverse elements such as assump-tions and core components of the APN. The attributes and descriptors presented in this paper are intended to promote a common vision to continue to enable a greater understanding by the international nursing and healthcare communities for the development of roles commonly identified as Clinical Nurse Specialist (CNS) and Nurse Practitioner (NP).

Female genital mutilation (FGM), a violation of girls’ and women’s human rights, is becoming less common, and opposition to the practice is growing — in the last two decades, the proportion of girls and women who want the practice to stop has doubled.
However, progress is not universal. In s...ome countries, FGM is as common today as it was three decades ago. Even in places where the practice is on the decline, progress would need to be at least 10 times faster to meet the 2030 target for elimination. Additionally, an alarming trend is emerging: around 1 in 4 girls and women who have undergone FGM, or 52 million worldwide, were cut by health personnel. This proportion is twice as high among adolescents, indicating growth in the medicalization of the practice.
This brochure explores the global FGM trends — progress made in the past three decades, shifts in attitudes, and changes in the circumstances surrounding the practice.

All young people, including those with special needs and from the most vulnerable groups, have the right to quality health care services. Unfortunately, this right is not a reality, particularly in the case of sexual and reproductive health services. Many youth in need of sexual and reproductive hea...lth care may either decline or be denied access to health services for a variety of reasons: Providers are often biased and do not feel comfortable serving youth who are sexually active; youth do not feel comfortable accessing existing services because they are not "youth-friendly" and may not meet their needs; and, often, community members do not feel that youth should have access to sexual and reproductive health services.
To address provider and site bias toward serving youth, EngenderHealth created a training curriculum intended to sensitize all staff at a health care facility on the provision of youth-friendly services. The curriculum was created as a result of the participatory work that we have been doing with youth in Nepal to address the needs of all levels of providers at different service-delivery settings. The curriculum has been field-tested and used in Nepal, Russia, Mongolia, and the United States.
Youth-Friendly Services allows staff to reflect upon and assess their own beliefs about adolescent sexuality while ensuring that those values and attitudes do not compromise the basic sexual and reproductive health rights to which youth are entitled. The curriculum also helps providers understand cross-cultural principles of adolescent development and health needs specific to youth. Once participant knowledge, attitudes, and skills are improved, sites conduct a self-assessment on the youth-friendliness of their services and create an action plan for specific improvements.
