Introduction. Leishmaniasis continues to be a neglected infectious disease of great importance, mainly affecting the poorest people with the least access to health services. In the Americas, it is a public health problem due to its magnitude, wide geographical distribution, and levels of morbidity and mortality. Objective. Summarize the recommendations included in Guideline for the Treatment of Leishmaniasis in the Region of the Americas, published by the Pan American Health Organization/World Health Organization, in order to provide adequate management of patients diagnosed with leishmaniasis, reduce clinical complications and deaths caused by drug toxicity, reduce the lethality of visceral leishmaniasis, and address key aspects of implementation of the guidelines. Methods. The guideline and its recommendations were summarized and a systematic search was carried out in PubMed, Lilacs, Health Systems Evidence, Epistemonikos, and gray literature for other studies conducted in the Region of the Americas, in order to identify barriers, facilitators, and implementation strategies. Results. Recommendations are presented, addressing the pharmacological treatment of patients diagnosed with cutaneous, mucosal, and visceral leishmaniasis in the Americas, as well as case management and secondary prophylaxis in patients coinfected with visceral leishmaniasis and HIV, and patients with other diseases that cause immunosuppression. Conclusions. The recommendations aim to provide the government entities and health professionals that care for leishmaniasis patients in the Americas with knowledge on management of the disease. Barriers are discussed (related to human resources, knowledge of guidelines, inputs, costs, access, and patient access), as well as facilitators and strategies to support implementation.

Introduction. Coronavirus disease 2019 (COVID-19) is an infectious disease caused by the SARS-CoV-2 virus. Most infected people will experience mild to moderate respiratory illness. However, some will become seriously ill and require medical attention. Older people and those with certain comorbidities are more likely to develop serious illness. Objective. To synthesize the recommendations included in Guidelines for Prophylaxis and Management of Patients with Mild and Moderate COVID-19 in Latin America and the Caribbean, and in Considerations on the Use of Antivirals, Monoclonal Antibodies, and Other Interventions for the Management of COVID-19 Patients in Latin America and the Caribbean, published by the Pan American Health Organization, in order to provide guidance on the prophylaxis and management of patients with mild to moderate COVID-19 and address key aspects of implementation. Methods. The guidelines and their recommendations were summarized. In addition, a systematic search was carried out in PubMed, Lilacs, Health Systems Evidence, Epistemonikos, and gray literature on other studies carried out in the Region of the Americas, in order to identify barriers, facilitators, and implementation strategies. Results. Twenty-one recommendations are presented, addressing the identification of markers and risk factors for mortality, prophylactic efficacy, pharmacological and non-pharmacological treatment, non-hospital management (including pregnant women and the pediatric population), use of diagnostic imaging studies, prophylaxis with anticoagulants, and follow-up. Conclusions. The recommendations seek to provide knowledge on the prophylaxis and management of patients with mild to moderate COVID-19 and offer considerations for implementation of the recommendations in the Region.

Objective. To develop an evidence map on visceral leishmaniasis prevention, control, diagnosis, treatment, and prognosis. Methods. Systematic reviews on visceral leishmaniasis were searched using MEDLINE/PubMed and Virtual Health Library. After selection, each included systematic review was assessed, characterized, and categorized by intervention type and by outcomes, according to the methodology offered by the PAHO/WHO Latin American and Caribbean Center on Health Sciences Information (BIREME). The methodological quality was assessed using the AMSTAR2 tool to determine the confidence level of the evidence obtained. Results. Among the prevention and control interventions, insecticide spraying, bednets, dog collars, and dog culling were the most assessed, emphasizing that insecticidal dog collars can reduce visceral leishmaniasis incidence in dogs. Regarding diagnosis, polymerase chain reaction (PCR), rK39 immunochromatographic test (rK39 ICT), and direct agglutination test (DAT) presented high sensitivity and specificity. As for treatment, pentavalent antimonials and amphotericin B were the most analyzed drugs and showed therapeutic success; however, serious adverse events can occur due to their use. The prognostic factors identified were anemia, edema, bleeding, jaundice, age, and HIV coinfection. Conclusions. The evidence map developed shows rK39 ICT and DAT as promising diagnostic alternatives and reinforces the efficacy of liposomal amphotericin B and pentavalent antimonials. Insecticide-impregnated dog collars appear as a promising measure for the control of visceral leishmaniasis, but there is also a need for future studies and reviews with higher methodological quality, especially on prevention and control interventions.

Introduction. Dengue, chikungunya, and Zika are viral diseases that pose a constant threat to public health. These three arboviruses can produce very similar clinical pictures, which represents a challenge to achieving an accurate clinical diagnosis and can lead to inadequate management and even fatal outcomes. Guidelines for the Clinical Diagnosis and Treatment of Dengue, Chikungunya, and Zika is part of the effort by the Pan American Health Organization and the countries of the Region of the Americas to prevent severe cases and death from these diseases, in a complex epidemiological context in which multiple factors favor transmission dynamics and lead to outbreaks and epidemics in the countries of the Region. Objectives. Synthesize the recommendations in the PAHO guidelines, published in 2022, in order to present appropriate diagnosis and treatment of these arboviruses, and to address aspects of implementation of the recommendations. Methods. The guidelines and their recommendations were synthesized. In addition, a systematic search was conducted in PubMed, Lilacs, Health Systems Evidence, Epistemonikos, and gray literature for studies done in the Region of the Americas, in order to identify barriers, facilitators, and implementation strategies. Process and outcome indicators for implementation of the recommendations were identified and formulated. Results. We present 12 recommendations applicable to adult and pediatric patients with suspected or confirmed dengue, chikungunya, or Zika, along with barriers, facilitators, and strategies for their implementation. Conclusions. The recommendations provide strategies for timely diagnosis and treatment of acute cases of dengue, chikungunya, and Zika, as well as considerations for implementation of the strategies.

Introduction. Chagas disease or American trypanosomiasis is caused by the flagellate protozoan Trypanosoma cruzi, transmitted mainly by insect vectors (popularly known in the different areas of the Region of the Americas as "kissing bugs", "pitos", "chinches", or "chirimachas" or "vinchuchas"). The parasite is transmitted via the placenta and in transfusions, and less frequently, orally or during organ transplantation. Because it was necessary to strengthen the implementation of public policies and the management of clinical conditions, given the diagnostic and therapeutic difficulties that this systemic parasitosis presents, the Pan American Health Organization (PAHO) developed guidance for the management of American trypanosomiasis. Objectives. Synthesize the recommendations included in the Guide for Diagnosis and Treatment of Chagas Disease, published (in Spanish only) by the Pan American Health Organization in 2018, in order to present the proper diagnostic methods and treatment for Chagas disease and to address aspects of its implementation. Methods. A summary was made of the guide and its recommendations. In addition, a systematic search was conducted in PubMed, Lilacs, Health Systems Evidence, Epistemonikos, and the gray literature for studies carried out in the Americas, in order to identify barriers, facilitators, and implementation strategies. Results. Ten recommendations are made. These are applicable to adult and pediatric patients with suspected Chagas disease, exposure to T. cruzi, or a confirmed diagnosis of acute, chronic, or congenital Chagas disease. Reports that addressed aspects of implementation were identified. Conclusions. The recommendations seek to provide strategies for the timely diagnosis and treatment of Chagas disease, as well as considerations for the implementation of such strategies. [ABSTRACT FROM AUTHOR]

OBJECTIVE: To describe and discuss the activities deployed by EVIPNet Brazil in 2013, highlighting the network's actions to promote evidence-based decision-making for the development and implementation of health policies. METHODS: A descriptive approach was employed to present the actions carried out by EVIPNet Brazil in 2013, especially processes relating to capacity-building, product development, and event participation. RESULTS: In 2013, 10 training programs were carried out (four technical meetings and six workshops), involving 34 institutions and 193 participants. One evidence brief for policy was reviewed and republished, and five others were developed. Moreover, one process of deliberative dialogue was conducted. A scientific paper was published on the experience of EVIPNet Brazil in the development of evidence-informed polices. The first issue of the EVIPNet Brazil Newsletter was published, along with the posting of news articles online. EVIPNet Brazil's actions were presented on national and international lectures, conferences, and round tables. The impacts of EVIPNet Brazil may be observed in the federal, state, and local contexts. CONCLUSIONS: A successful development, implementation, and monitoring of evidence-informed policies depends on actions such as those carried out by EVIPNet, including professional capacity-building to help expand and consolidate the network, creation of new local Health Evidence Centers to encourage the use of evidence in decision-making, production of evidence briefs for health policies, and organization of deliberative dialogues.

Objective. To describe the impact, at the public maternity facility of a university hospital in Brazil, of the rapid implementation of new guidelines recommended by national consensus panels concerning the prevention of vertical HIV transmission. Method. We performed a retrospective study of deliveries by HIV-infected women at the public maternity facility of a university hospital in the city of Campinas, São Paulo, Brazil, from 1990 through 2000. The guidelines utilized at the facility during this period were: (1) from 1990 through 1994, contraindication to breast-feeding and no use of antiretroviral drugs; (2) 1995 and 1996, use of zidovudine (AZT) by the pregnant woman and the newborn; (3) 1997 and 1998, use of AZT according to the ACTG 076 protocol; and (4) 1999 and 2000, multiple antiretroviral agents and elective cesarean delivery. All the antiretroviral drugs were provided for free by Brazil's public health care system. The vertical transmission rate was calculated for each of the four stages, and the risk ratio for congenital transmission was calculated for each stage and for each prophylactic intervention separately (breast-feeding, type of antiretroviral drug, type of delivery). Results. We studied 197 deliveries at the public maternity facility over that 19902000 period. Over the four stages, the rate of vertical transmission decreased: it was 32.3% in the first stage, 25.7% in the second, 2.2% in the third, and 2.9% in the fourth. The most pronounced decrease, observed from the second to the third stage, occurred after introduction of the full ACTG 076 regimen. The use of combined antiretroviral agents increased from 0% in the first stage to 46.4% in the fourth stage. There were no cases of vertical transmission in pregnant women treated with multiple drugs. The risk of vertical HIV transmission was 5 times as great with breast-feeding vs. no breast-feeding (risk ratio = 5.06), 5 times as great with no antiretroviral therapy vs. the full ACTG 076 regimen (risk ratio = 5.29), and 4 times as great with forceps delivery vs. elective cesarean delivery (risk ratio = 4.13). Conclusion. The timely adoption of up-to-date interventions recommended by national consensus panels, along with the free provision of antiretroviral drugs, was effective in reducing congenital HIV transmission in this public maternity facility. The interaction between the university hospital health service and the public health service reduced the time needed for implementation of proven, effective interventions, and this experience could serve as an example for other maternal and perinatal health situations.
