Background: Cardiovascular diseases (CVD) have significant health and economic burdens. In South America, the loss of productivity related to these diseases has not yet been well explored.

Objective: Estimate the potentially productive years of life lost (PPYLL) and loss of productivity related to premature mortality associated with CVD in South America, in 2019.

Sugar-sweetened beverages (SSBs) are a major source of added sugar and are associated with noncommunicable diseases (NCDs) such as obesity and diabetes. This study assessed the impact of SSBs consumption on disease burden in Brazil, including deaths, disability-adjusted life years (DALYs), and healthcare costs. A 3-stage methodology was used to assess the direct effects of SSBs on diabetes, cardiovascular diseases, and body mass index (BMI), along with the influence of BMI on disease incidence.

In order to prioritize public policies to reduce the consumption of sugar-sweetened beverages in Argentina, Brazil, El Salvador and Trinidad and Tobago and to identify information gaps related to the burden of disease attributable to their consumption, a policy dialogue was held with government members, civil society organizations, researchers and communicators from Latin American and Caribbean countries. Presentations and deliberative workshops were conducted using semi-structured data collection tools and group discussions. The prioritized interventions were tax increases, front labeling, restriction of advertising, promotion and sponsorship, and modifications regarding the school environment.

Candidemia and other forms of invasive candidiasis (C/IC) are serious conditions, especially for immunosuppressed individuals with prolonged hospitalization in intensive care units (ICU). This study analyzed the incremental cost-effectiveness and budgetary impact (BI) of treatment for IC with anidulafungin compared to amphotericin B lipid complex (ABLC) and amphotericin B deoxycholate (ABD) or conventional amphotericin B (CAB), in the Brazilian Unified Health System (SUS). A decision model was conducted with a time horizon of two weeks from the perspective of SUS.

Objectives: Cryptococcal meningitis constitutes a significant source of mortality in the developing world. Annually, approximately 625 000 deaths occur worldwide among patients with human immunodeficiency virus (HIV) infection. This study aims to assess the cost-effectiveness of implementing cryptococcal antigen lateral flow assay (CRAG-LFA) screening in Brazil compared with the current practice.

Cryptococcal infection is a frequent cause of mortality in Brazilian HIV-infected patients. The present study aimed to evaluate the cost-effectiveness and budgetary impact of four cryptococcosis screening strategies in HIV-infected patients with CD4+ ≤ 200 cells/mm3, in Brazil. A Monte Carlo microsimulation was used to compare the following diagnostic tests: a systematic serum cryptococcal antigen (CRAG) screening with latex agglutination (CRAG-LA), a lateral flow immunochromatographic test (CRAG-LFA), India ink staining and no intervention.

Cancer in individuals 0 to 19 years of age is considered rare when compared to incidence in older age brackets, and is estimated at 2% to 3% of all malignant tumors recorded in Brazil. The use of anthracyclines is frequently associated with cardiotoxicity, and these drugs are part of approximately 60% of treatment protocols in pediatric oncology. Among the existing strategies for the prevention of cardiotoxicity, dexrazoxane obtained favorable results based on intermediate outcomes (biochemical markers and echocardiographic parameters).

Introduction: Acute lymphoblastic leukemia (ALL) is the cancer with the highest incidence in childhood and adolescence, and pharmacotherapy is the primary form of treatment.

Objective And Methods: A systematic review of the efficacy and safety of polyethylene glycol (PEG)-asparaginase in acute lymphoblastic leukemia therapy in children and adolescents was conducted to compare it with native Escherichia coli L-asparaginase. PubMed, Web of Science, Science Direct, Cochrane Library, Scopus, LILACS (Latin American and Caribbean Health Sciences Literature) and EMBASE databases were selected.

Background: Diarrhea causes, annually, approximately 1.7 billion cases and 760,000 deaths worldwide among children under 5 years of age, although these are preventable and treatable. This study aim to assess the cost-effectiveness for the treatment of diarrhea in emergency services in the management of children of acute gastroenteritis with non-severe dehydration.

Objective: To investigate the impact of combined use of fixed and mobile mammography units to rationalize the management of breast cancer screening programs and increase population coverage.

Methods: An observational study was performed using agents-based modeling. The model was used to simulate breast cancer screening coverage in a specific region in the state of Rio de Janeiro () where 22 fixed mammography units are installed.

Objective: To perform a cost-effectiveness analysis of donepezil and rivastigmine therapy for mild and moderate Alzheimer's disease (AD) from the perspective of the Brazilian Unified Health System.

Method: A hypothetical cohort of 1,000 individuals of both sexes, aged >65 years, and diagnosed with AD was simulated using a Markov model. The time horizon was 10 years, with 1-year cycles.

This article has two parts. The first discusses the relationship between industry and health interests based on three different but non-mutually exclusive "logics": (a) independent; (b) divergent; and (c) convergent. The second part describes the experience at the Brazilian National Institute of Traumatology and Orthopedics (INTO) with a technology management model.

Recent evidence has demonstrated that slow responders may benefit from antiviral treatment in HCV/HIV coinfection. This study aimed to evaluate the cost-effectiveness of HCV treatment in individuals with genotype 1 coinfected with HIV, with peg-interferon in combination with ribavirin, compared to the inclusion (versus non-inclusion) of slow responders. A Markov model was developed that simulated the progression of liver disease in a hypothetical cohort of one thousand men over 40 years of age, considering the Brazilian Unified National Health System (SUS) perspective and a 30-year timeline.

A cost-effectiveness analysis was conducted in screening for breast cancer. The use of conventional mammography, digital and magnetic resonance imaging were compared with natural disease history as a baseline. A Markov model projected breast cancer in a group of 100,000 women for a 30 year period, with screening every two years.

The aim of this paper is to examine the Ministry of Health of Brazil investments in research and development in health (R&D/H) between the years of 2000-2002, trying to contrast them with the items of the National Health Research Priority Agenda, in order to attempt a base line that makes capable future evaluations on the inductor role. The data was collected by a research carried out with the main goal of measure resources invested in R&D/H in the country on the period, considering only the Ministry of Health investments. The researches were independently categorized by 2 researchers based on 24 subdivisions which compose the Agenda.
