Objective. The objective of this study was to investigate the funding received by papers of excellence on smoking at the global level between 2010 and 2014 through the Web of Science, and to find out if funding is associated with greater impact. Method. We searched the Science Citation Index Expanded (SCIE) and the Social Sciences Citation Index (SSCI) through the Web of Science platform on 20 May 2015 (typology consisting of originals and reviews for the period from 2010 to 2014). The search strategy was “smok*” OR “tobac*.” To select the papers of excellence, we picked those that had an h index (i.e., number of articles having at least that many citations) from among the papers in the overall sample generated by the strategy. Results. Of the 193 papers of excellence on smoking that were identified, 158 had received funding from 279 different financing institutions that intervened 522 times. The funding came primarily from government agencies, private foundations, and the pharmaceutical industry. Public funding declined and private funding increased over the years included in the analysis. Receipt of funding was not associated with greater impact at a later date. Conclusions. Most of the papers of excellence on smoking received external funding primarily from government agencies, private foundations, and the pharmaceutical industry. Public funding has decreased, while private funding has increased. Receipt of funding was not associated with greater impact at a later date. [ABSTRACT FROM AUTHOR]

Objective. Describe the quality of life of health personnel, the work environment, and interactions between employees and their work environment during the pandemic. Methods. A scoping review was conducted. The electronic databases PubMed, Cumulative Index of Nursing and Allied Literature Complete, and Google Scholar were used, as well as the repositories of the World Health Organization and the Centers for Disease Control and Prevention. Primary, secondary, and grey literature studies published between December 2019 and March 2021 in Spanish, English, and Portuguese were included. Methodological quality was assessed using the Authority, Accuracy, Coverage, Objectivity, Date and Importance (AACODS) checklist; a tool for the measurement of multiple systematic reviews (AMSTAR); and the Critical Appraisal Checklist for Text and Opinion Papers. A thematic analysis was carried out based on the quality-of-life and well-being model. Results. Of a total of 208 articles, 11 were included. The quality of life of health personnel during the COVID-19 pandemic was affected by the characteristics of health personnel, the work environment, and interactions between employees and their work environment. Problems related to psychosocial and occupational factors were observed. Discussion. The quality of life of health personnel was characterized by stigmatization, stress, anxiety, and fatigue. Organizational management and the implementation of psychological interventions appear to affect interactions between employees and their work environment, and improve their quality of life.

HEARTS in the Americas is the regional adaptation of the World Health Organization's Global Hearts Initiative, which will be the model for risk management for cardiovascular disease (CVD) in primary health care in the Region of the Americas by 2025. It has already been implemented in 21 countries and 1045 primary health care centers throughout Latin America and the Caribbean. It takes a public health and health systems approach to systematically introduce simplified interventions at the primary health care level and focuses on hypertension as a clinical entry point. This paper introduces a new, improved application (app), the main component of which is the calculator for CVD risk and hypertension management. The paper summarizes the risk assessment approach and the methodology used by the World Health Organization to update its cardiovascular risk charts in 2019; describes the app, its use, functionality and validation process; and provides a set of practical recommendations for optimizing CVD risk and hypertension management by using the app in clinical practice. The HEARTS app is a powerful tool to improve the quality of care provided in primary health settings. The creation and dissemination of the HEARTS app is an essential step in the journey towards eliminating preventable CVD in the Americas. [ABSTRACT FROM AUTHOR]

HEARTS in the Americas is the Pan American Health Organization flagship program to accelerate the reduction of the cardiovascular disease (CVD) burden by improving hypertension control and CVD secondary prevention in primary health care. A monitoring and evaluation (M&E) platform is needed for program implementation, benchmarking, and informing policy-makers. This paper describes the conceptual bases of the HEARTS M&E platform including software design principles, contextualization of data collection modules, data structure, reporting, and visualization. The District Health Information Software 2 (DHIS2) web-based platform was chosen to implement aggregate data entry of CVD outcome, process, and structural risk factor indicators. In addition, PowerBI was chosen for data visualization and dashboarding for the analysis of performance and trends above the health care facility level. The development of this new information platform was focused on primary health care facility data entry, timely data reporting, visualizations, and ultimately active use of data to drive decision-making for equitable program implementation and improved quality of care. Additionally, lessons learnt and programmatic considerations were assessed through the experience of the M&E software development. Building political will and support is essential to developing and deploying a flexible platform in multiple countries which is contextually specific to the needs of various stakeholders and levels of the health care system. The HEARTS M&E platform supports program implementation and reveals structural and managerial limitations and care gaps. The HEARTS M&E platform will be central to monitoring and driving further population-level improvements in CVD and other noncommunicable disease-related health. [ABSTRACT FROM AUTHOR]

Cardiovascular disease (CVD) is the leading cause of death in the Americas and raised blood pressure accounts for over 50% of CVD. In the Americas over a quarter of adult women and four in ten adult men have hypertension and the diagnosis, treatment and control are suboptimal. In 2021, the World Health Organization (WHO) released an updated guideline for the pharmacological treatment of hypertension in adults. This policy paper highlights the facilitating role of the WHO Global HEARTS initiative and the HEARTS in the Americas initiative to catalyze the implementation of this guideline, provides specific policy advice for implementation, and emphasizes that an over-arching strategic approach for hypertension control is needed. The authors urge health advocates and policymakers to prioritize the prevention and control of hypertension to improve the health and wellbeing of their populations and to reduce CVD health disparities within and between populations of the Americas.

Objective. To determine the relative risk of a lethal outcome associated with chronic degenerative conditions in patients with COVID-19. Methods. A cohort study was conducted using electronic medical records belonging to patients who tested positive for COVID-19 on RT-PCR while receiving care as outpatients or inpatients in a social security system facility between March 2020 and March 2021. Two study groups were formed. The exposed group was divided into four subgroups, each of which was diagnosed with one and only one chronic condition (diabetes, hypertension, obesity, or chronic kidney disease); the unexposed group was obtained from the medical records of patients without comorbidities. A total of 1 114 medical records were examined using simple random sampling. Once the minimum sample size was reached, the relative risk was calculated for each chronic condition. Combinations of two, three, and four conditions were created, and each of them was included in the analysis. Results. In the absence of a chronic degenerative condition, the prevalence of a lethal outcome from COVID-19 is 3.8%; in the presence of type 2 diabetes mellitus, 15.8%; in the presence of arterial hypertension, 15.6%; and in the presence of obesity, 15.0%. For diabetes and hypertension combined, the prevalence of a lethal outcome is 54.1%; for diabetes and obesity combined, 36.8%, and for obesity and hypertension combined, 28.1%. Conclusion. In patients with COVID-19, the relative risk of a lethal outcome is 4.17 for those with diabetes, 4.13 for those with hypertension, and 3.96 for those with obesity. For two chronic conditions combined, the relative risk doubles or triples. The relative risk of a lethal outcome is 14.27 for diabetes plus hypertension; 9.73 for diabetes plus obesity, and 7.43 for obesity plus hypertension. Chronic conditions do not present alone; they generally occur together, hence the significance of the relative risks for lethal outcomes presented in this paper. [ABSTRACT FROM AUTHOR]

This paper presents the position of the Latin American working group of the International Foundation for Integrated Care (IFIC). The working group brings together various Latin American actors and organizations in support of actions that facilitate the transformation of health systems in the region towards integrated systems that focus on people not as isolated individuals but as subjects of law in the complex social and environmental contexts where they live and interact. The working group proposes nine pillars of integrated care to be used as a conceptual framework for policy development and changes in practices: 1) shared vision and values; 2) population health; 3) people and communities as partners; 4) resilient communities; 5) capacities of human resources for health; 6) governance and leadership; 7) digital solutions; 8) aligned payment systems; and 9) public transparency. Based on these pillars, lines of work are proposed to strengthen alliances and networks, advocacy, research, and capacity-building, in order to help develop health and social systems that are effectively integrated and focused not only on people but also on communities in Latin America.

At the 2003 meeting of the Directing Council of the Pan American Health Organization (PAHO), the PAHO Member States issued a mandate to strengthen primary health care (Resolution CD44.R6). The mandate led in 2005 to the document "Renewing Primary Health Care in the Americas. A Position Paper of the Pan American Health Organization/WHO [World Health Organization]," and it culminated in the Declaration of Montevideo, an agreement among the governments of the Region of the Americas to renew their commitment to primary health care (PHC). Scientific data have shown that PHC, regarded as the basis of all the health systems in the Region, is a key component of effective health systems and can be adapted to the range of diverse social, cultural, and economic conditions that exist. The new, global health paradigm has given rise to changes in the population's health care needs. Health services and systems must adapt to address these changes. Building on the legacy of the International Conference on Primary Health Care, held in 1978 in Alma-Ata (Kazakhstan, Union of Soviet Socialist Republics), PAHO proposes a group of strategies critical to adopting PHC-based health care systems based on the principles of equity, solidarity, and the right to the highest possible standard of health. The main objective of the strategies is to develop and/or strengthen PHC-based health systems in the entire Region of the Americas. A substantial effort will be required on the part of health professionals, citizens, governments, associations, and agencies. This document explains the strategies that must be employed at the national, subregional, regional, and global levels. [ABSTRACT FROM AUTHOR]

In 2005, shortly after ratifying the Framework Convention on Tobacco Control (FCTC), Uruguay began an ambitious tobacco control campaign that brought the country to the global forefront in the fight against smoking. The wide range of measures implemented in a relatively short period and the rigorousness with which policies were implemented and enforced have few precedents, even in the most developed countries. This paper presents a synthesis and update of several papers by the authors that evaluate different aspects of the campaign ten years following ratification of the FCTC. In particular, these research studies highlight the campaign's aggregate impact on the drop in prevalence of current tobacco consumption in adult and youth populations, and on decisions by pregnant women to quit smoking (1, 2), as well as the relative impact of tax policies in relation to non-price tobacco control measures. The analyses are based on observational studies (at the population or individual level) that use external (Argentina and Chile) and internal (nonsmokers) control groups. Pending challenges in the design of antismoking policies are also discussed. [ABSTRACT FROM AUTHOR]

Failure to establish a contingency plan prior to a public health emergency can have catastrophic consequences. The threat of a new influenza pandemic has prompted countries to draft national strategic preparedness plans to prevent, mitigate, and recover from a potential influenza pandemic. This paper examines these preparations in Latin America and the Caribbean and describes potential scenarios of pandemic impact on the burden of mortality and on health services in the Region. In particular, the paper reports on the progress made by Member States in developing national influenza pandemic preparedness plans and implementation mechanisms at both the national and local levels. These achievements were facilitated through a series of planning workshops and self-assessment exercises conducted by PAHO for intersectoral country teams and guided by the WHO global influenza preparedness plan. Although significant progress has been made in plan completeness, intercountry preparedness planning and local level implementation remain key challenges. Multisectoral partnerships are clearly paramount to securing the commitment and resources needed to reach and sustain effective pandemic preparedness in the Americas. [ABSTRACT FROM AUTHOR]

Objective. To compare two methods--the "ballot box" method and the "indirect questioning" method--for estimating the frequency of induced abortions in population-based studies. Methods. A cross-sectional population-based study was conducted with a representative sample of 3 002 women between 15 and 49 years of age living in the city of Pelotas, Rio Grande do Sul, Brazil. The women were selected through multistage sampling and randomly assigned to answer questions concerning induced abortion with one of the two methods, after they had answered a general questionnaire that collected socioeconomic and demographic information. With the "ballot box" method, women received a small piece of paper containing direct questions on abortion. Each woman marked her answers on the paper and then deposited it into a small "ballot box" carried by the interviewer, thus assuring the confidentiality of the responses. With the second method, the interviewer verbally asked the woman a series of questions that indirectly inquired about abortion. Results. Among the women assigned to the ballot box method, 7.2% reported having induced at least one abortion, versus 3.8% of the women assigned to the indirect questioning method. The ratio between the two methods was 1.89 (95% confidence interval: 1.39 to 2.60; P < 0.001). Of the women surveyed who were 45-49 years old (at, the end of their reproductive life) and answered using the ballot box method, 12% of them reported having had at least one induced abortion in their lifetime. Among the women who answered using the ballot box method, the main reasons they gave for having had an abortion were economic difficulties, being too young, and being single. Approximately half of the women responding to the ballot box method questions reported they had used unsafe procedures to induce abortion, with 13% of them using misoprostol. Conclusions. The ballot box method was suitable for studying the frequency of induced abortion and for researching... [ABSTRACT FROM AUTHOR]

Objective. In 2014, the Pan American Health Organization member countries signed the Strategy for Universal Access to Health and Universal Health Coverage. In it, they committed to increasing public health expenditure until reaching the benchmark of 6% of gross domestic product (GDP). The objective of this paper is to determine, for each country in the Region, if they can reach this goal by economic growth alone and, if so, how long it would take. Methods. Using World Bank and World Health Organization data, elasticity of public health expenditure with regard to GDP was estimated for each country. Real economic growth and International Monetary Fund projections for 2016-2021 were used to project the expenditure series and determine the year each country would reach 6% of GDP. Results. Six countries have already reached the 6% goal. The Latin American and Caribbean countries that have achieved it are those that have single health systems, based on universal access and coverage. If current prioritization of public health expenditure is maintained, three countries could reach the goal in the next decade. Four more countries would reach it before mid-century, ten in the second half of the century, and one would have to wait until the next century. Finally, 13 countries would never reach the proposed goal. Conclusions. This analysis demonstrates the limitations of economic growth as a source of fiscal space. Other sources will need to be tapped, such as increased tax collection, specific health taxes, and greater efficiency in public spending, which will require social and political dialogue in the countries regarding their commitment to universal health principles.

Due to its impact on human health and its capacity to cause damage, disasters are one of the global problems that most concern the international community. However, and in spite of the efforts made by many health systems, the reduction of vulnerabilities and the lack of strategies to avoid or minimize risks have not received enough attention yet. As Cuba is located in an area of permanent danger of disasters, its health sector has accumulated considerable experience in the management of risks and in the assurance of less risky future scenarios, with active participation of the community and a planned and organized process to address the impact of climate change. This paper summarizes some of these experiences and describes the dangers, vulnerabilities, and risks of disasters in Cuba, its Civil Defense System, and planning and organization in the health sector for disaster reduction, as well as the main effects and challenges of climate change in the health system. Lessons learned and good practices support the key role of human resources to reduce vulnerabilities; the greatest challenges are to avoid or minimize risks, to advance research, to train professionals for climate change, and to optimize the organization of health systems and services in the country.

The purpose of this paper is to describe the opportunities and challenges of training processes in the coordination of regional and national communication initiatives for arboviral disease prevention, using the lessons learned in the Cuban context as an example. In February 2016 and December 2017, professional staff from the Pedro Kourí Institute of Tropical Medicine attended workshops for strengthening communication capacities for arboviral disease prevention in primary health care settings through gradual introduction of the most recent approaches promoted by the Pan American Health Organization in this regard. National, provincial, municipal, and health area specialists with diverse professional profiles were trained; multidisciplinary teams were strengthened at the different levels; specific tasks were assigned and coordinated at each level; and demonstration sites were established for the communication approaches promoted in the workshops. Learning needs in the field of mass communication were also identified, and activities for training technical staff and for monitoring and evaluation were introduced in the national strategy 2018-2021 to guarantee the implementation and sustainability of communication activities. Notwithstanding, participating institutions will have to address the challenges characteristic of communication for arboviral disease prevention, which include the rotation of trained personnel, the mobilization of resources for communication, and the identification of appropriate evaluation indicators.

The objective of this paper is to describe the current situation of mental health in Ecuador. In Ecuador, although the model of community mental health has been integrated into primary health care services for a decade, its implementation does not seem to have the expected results. It is pertinent to explore the causes of this situation and to propose alternatives, taking into account the contributions of social medicine, collective health and participatory action research as emblematic models in Latin America in the field of mental health. For an effective implementation of community mental health in primary care in Ecuador, the role of universities is central, specifically in projects linked to the community and in pre-professional practices in health sciences careers. These projects allow the promotion of community mental health in the first level of health care from a critical perspective, open to complexity and based on the principle that the community is the main active subject of social transformation.

This paper presents, in the context of the universal health strategy, some general considerations and economic actions on financing, efficiency and other economic challenges of public health in Cuba. Official bibliographic sources of the Cuban state were revised up to 2015. The analyses of time series were adjusted to constant prices of 1997 and the official exchange rate of 1 Cuban peso = 1 US dollar. The Cuban National Health System has a solid infrastructure, consisting of a wide network of health facilities that guarantee full coverage, access and equity in the services provided to the population through qualified human resources. An economic analysis was carried out under the conceptual framework of the universal health strategy, with an emphasis in financing, efficiency and challenges of the Cuban public health system to maintain the right to health of its citizens, equity, coverage and access to the services provided, including the elimination of economic, sociocultural and gender barriers, as well as solidarity with the Cuban population and the world. It was concluded that in Cuba, universal health is considered one of its most valuable achievements, although it is needed a most efficient analysis of reliable and available sources, research and application of results to practice on the strengths and weaknesses of the system regarding health economics, updating and a better use of resources and technologies, as well as deepening the lessons learned and facing remaining challenges.

The achievements and challenges arising from the application of eHealth in the Cuban context to support universal health are presented. The Ministry of Public Health defi- ned the Computerization Strategy, whose lines of work are based on the components declared in the Strategy and Plan of Action on eHealth of the Pan American Health Organization, and in the Policy for the Computerization of the Society, approved by the Cuban Government. The paper describes the actions of the Cuban strategy elaborated to solve the limitations in the technological infrastructure, to develop the platforms, the tools and the applications required by the health services, and to stimulate the professionals' abilities to use them. The results of eHealth in Cuba are based on the application and evaluation of the strategy implemented in the framework of the improvement of the health sector through projects such as the electronic medical record called Galen Clínicas, the training of human resources and the resources for information and education from the Infomed Health Telematics Network. These models of solidarity and collaborative networking have contributed to universal health and positively impacted on the health system beyond the borders. The challenges of eHealth are the development of initiatives in mobile health --in which there is little experience--; telemedicine --a project that is stopped--; integration and interoperability among applications; the sustainability of the implemented solutions; insufficient technological infrastructure; and strengthening of the legal framework.

Violence against women is considered a public health problem that affects women worldwide. Recently, the Directing Council of the Pan American Health Organization declared its serious socioeconomic impact in the Region of the Americas and committed to undertaking actions in the health services to address this problem. Within that framework, this paper describes the steps of a participatory action research (PAR) approach that is being implemented in the Wenteche Territory of the La Araucanía region of Chile, which aims to strengthen community bonds, rekindle opportunities for dialogue with and among the people of the territory, foster social participation and democracy in the generation of pertinent, participatory knowledge regarding this problem, and obtain information to support design of an intervention model adapted to local characteristics.

Objectives. Prenatal care is a pillar of public health, enabling access to interventions including prevention of mother-to-child transmission of HIV and congenital syphilis. This paper describes social factors related to use of prenatal care in Ecuador. Methods. In 2011 and 2012, participant clinical history and interview information was analyzed from a national probability sample of 5 998 women presenting for delivery or miscarriage services in 15 healthcare facilities in Ecuador, to estimate prevalence of HIV, syphilis, and Chagas disease, and prenatal care coverage. Results. The study found that 94.1% of women had attended at least one prenatal visit, but that attendance at no less than four visits was 73.1%. Furthermore, lower educational level, greater number of pregnancies, occupation in the agriculture or livestock sector, and membership in ethnic indigenous, Afro-Ecuadorian, or other minority groups were factors associated with lack of use (no prenatal visits) or insufficient use of prenatal care (fewer than four visits or first visit at >20 weeks gestation) in Ecuador. Conclusions. These results point to persistence of marked inequalities in access to and use of prenatal health services attributable to socioeconomic factors and to the need to strengthen strategies to address them, to reach the goal of universal prenatal care coverage.

The Region of the Americas has been affected since December 2013 by a chikungunya epidemic for the first time. Although the first cases were recorded in the French Caribbean, the epidemic quickly spread to the Dominican Republic due to trade and people movements. The Dominican Republic, which shares the island of Hispaniola with Haiti, has a population of 10 million. This article contains information from a range of different publications and official documents about the chikungunya virus infection and epidemic. These papers were extremely helpful for guiding the response to the epidemic in the Dominican Republic and may also be useful for enhancing knowledge of the virus and responses among health workers elsewhere in the region. Particular attention is drawn to the important research undertaken in countries and territories affected by the epidemic in the Indian Ocean area. This is the case, for example, of the island of La Réunion, where the epidemic had an attack rate of more than 30% between 2005 and 2007. Researchers were able to identify risk groups, severe and atypical forms of the infection, cases of vertical transmission, chronic disease causing recurrent pain over three years, and directly- or indirectly-related deaths from the virus. Given its high attack rate, the chikungunya virus has emerged as an exceptional challenge for health ministries and calls for appropriate organized responses from the health services, prioritization of care for risk groups and patients exhibiting severe forms of the disease, and effective social communication and intersectoral actions.

Health information systems play a key role in enabling high quality, complete health information to be available in a timely fashion for operational and strategic decision-making that makes it possible to save lives and improve the health and quality of life of the population. In many countries, health information systems are weak, incomplete, and fragmented. However, there is broad consensus in the literature of the need to strengthen health information systems in countries around the world. The objective of this paper is to present the essential components of the conceptual framework to strengthen health information systems in Peru. It describes the principal actions and strategies of the Ministry of Health of Peru during the process of strengthening health information systems. These systems make it possible to orient policies for appropriate decision-making in public health. [ABSTRACT FROM AUTHOR]

Latin America is adopting regulations that bear on medicinal costs and spending. The regulations have four main goals: i) to guarantee a competitive market, ii) to ensure affordability for individual consumers (commercial channel),iii) to contain public spending on medicines (institution channel), and iv) to guarantee efficient spending on medicines.The experience of Latin America differs from that of countries in developed regions. In the latter, the countries and to have similar policies, both in promoting generic medicines and in price control strategies, and in optimizing and containing pharmaceutical expense. In contrast,in Latin America, certain institutional weaknesses impede the consolidation and application of an effective regulatory policy. This paper reviews the experience gained through the adoption of economic regulations aimed at reducing spending and improving access to medicines, suggests lessons learned at the international level, and offers recommendations for the countries of Latin America. Its purpose is to offer key elements to decision-makers and the authorities of the countries concerned in pursuing economic regulation of medicines. [ABSTRACT FROM AUTHOR]

Research on health policies is considered essential to ensure the effectiveness and efficiency of public policies. Analyses of public health policies have various objectives, including helping to solve the problems for which the policy was originated. That objective faces two large obstacles: (1) the ambiguity and heterogeneity of the models applied for the analysis of public policies, conditions that hinder the selection of analytical methods and the assessment of the scope of the objective; and (2) the traditional methodological approaches that limit the capacity of analyses to help solve the problems detected. This paper reviews the epistemology of the predominant models of public health policy analysis in order to assess their scope and limitations. It concludes that the development of new conceptual approaches could improve the quality of research on public policies and their ability to favorably impact decisions. [ABSTRACT FROM AUTHOR]

Objective. This paper describes the analytical methodology and overall distribution of these consultations--particularly respiratory consultations--for children under 15 years of age in Santiago de Chile, Chile. The aim is to understand differences by age groups, as well as seasonal trends and trends over the years. Methods. The research covered the distribution of consultations and their evolution over a period of 17 years. Information was collected on a daily basis from all pediatric consultations, grouped into nonrespiratory and acute respiratory categories, in seven sentinel centers of Santiago de Chile. Results. Between January 1993 and December 2009, 1 947 477 cases of pediatric illnesses were recorded, of which 1 188 029 (61.0%) were for respiratory causes. Of those, 656 567 (33.7%) were for acute lower respiratory tract illnesses, 418 932 (21.5%) were for broncho-obstructive syndrome, and 48 669 (2.5%) were for pneumonia. Pneumonia and broncho-obstructive syndrome were more frequent in children under age 5. Lower respiratory tract illnesses, broncho-obstructive syndrome, and pneumonia showed a significant downward trend during the period observed. Lower respiratory tract illnesses are the leading cause of pediatric morbidity in primary health care, while broncho-obstructive syndrome is the leading specific reason for pediatric consultations. Conclusions. These results point to the need to allocate or reallocate resources for programs for promotion, education, prevention, and treatment of these illnesses with the targeting necessary to address seasonal variations.

In Ciudad Juarez, Chihuahua, Mexico, morbidity and mortality from injuries have increased alarmingly since 2008. This paper aims to examine the changes in the number of hospital discharges for external injuries recorded during the 2008-2010 period in a hospital in Ciudad Juarez. A descriptive retrospective study conducted at the Ciudad Juarez General Hospital looked at the incidence of external injuries as the reason for hospital discharges during the period under analysis. The average proportion of hospital discharges attributed to external injuries was 27%, with the 25-44-year-old age group being the most affected. More than half of the discharges were for fractures. The incidence rate of hospital discharges attributed to injuries in Ciudad Juarez was almost four times greater than that reported at the national level. [ABSTRACT FROM AUTHOR]

The Region of the Americas, with a homicide rate of 16.4 per 100,000 population (2004), is the second most violent region in the world, but public policy-making for the prevention of violence and crime is hampered by the absence of reliable and comparable data on the problem's various manifestations. This paper describes a 14-country initiative, sponsored by the Inter-American Development Bank in partnership with other regional agencies, to develop-collectively and by consensus- indicators for peaceful coexistence and citizen security that permit comparisons among countries, systematization of methods for the production and collection of pertinent data, the development of regional policies, and the dissemination and sharing of good practices. The selected indicators were homicide, death from road traffic injuries, suicide, death by firearm, sexual crime, family violence, child abuse, robbery, theft, vehicle theft and robbery, abduction, traffic offenses committed while under the influence of alcohol, general victimization, victimization by theft, victimization by robbery, perception of insecurity, perception of fear, confidence in institutions, and justification of the use of violence. For each indicator, agreement was reached on the type of measurement and the minimum variables that should be taken into account to have appropriate criteria for comparison. [ABSTRACT FROM AUTHOR]

Research on health policies is considered essential to ensure the effectiveness and efficiency of public policies. Analyses of public health policies have various objectives, including helping to solve the problems for which the policy was originated. That objective faces two large obstacles: (1) the ambiguity and heterogeneity of the models applied for the analysis of public policies, conditions that hinder the selection of analytical methods and the assessment of the scope of the objective; and (2) the traditional methodological approaches that limit the capacity of analyses to help solve the problems detected. This paper reviews the epistemology of the predominant models of public health policy analysis in order to assess their scope and limitations. It concludes that the development of new conceptual approaches could improve the quality of research on public policies and their ability to favorably impact decisions. [ABSTRACT FROM AUTHOR]

The Region of the Americas, with a homicide rate of 16.4 per 100,000 population (2004), is the second most violent region in the world, but public policy-making for the prevention of violence and crime is hampered by the absence of reliable and comparable data on the problem's various manifestations. This paper describes a 14-country initiative, sponsored by the Inter-American Development Bank in partnership with other regional agencies, to develop-collectively and by consensus- indicators for peaceful coexistence and citizen security that permit comparisons among countries, systematization of methods for the production and collection of pertinent data, the development of regional policies, and the dissemination and sharing of good practices. The selected indicators were homicide, death from road traffic injuries, suicide, death by firearm, sexual crime, family violence, child abuse, robbery, theft, vehicle theft and robbery, abduction, traffic offenses committed while under the influence of alcohol, general victimization, victimization by theft, victimization by robbery, perception of insecurity, perception of fear, confidence in institutions, and justification of the use of violence. For each indicator, agreement was reached on the type of measurement and the minimum variables that should be taken into account to have appropriate criteria for comparison. [ABSTRACT FROM AUTHOR]

Objectives. To assess the susceptibility status of 13 natural populations of Aedes aegypti (collected from sites in Colombia where dengue is a serious public health problem) to the pyrethroids, deltamethrin and lambda-cyhalothrin, and to the organochlorine, DDT, and to identify any biochemical mechanisms associated with resistance. Methods. Immature forms of the vector were collected from natural breeding spots at each site and then raised under controlled conditions. Using the F2 generation, bioassays were performed using the World Health Organization's 1981 methodology (impregnated paper) and United States Centers for Disease Control and Prevention's 1998 methodology (impregnated bottles). In populations where mortality rates were consistent with decreased susceptibility, levels of nonspecific esterases (NSE), mixedfunction oxidases (MFO), and acetylcholinesterase (AChE) were measured using colorimetric tests. Results. All of the mosquito populations that were tested showed resistance to the organochlorine DDT. In the case of the pyrethroids, widespread resistance to lambdacyhalothrin was found, but not to deltamethrin. Assessing the biochemical resistance mechanisms showed that 7 of the 11 populations had elevated NSE, and one population, increased MFO. Conclusions. Physiological cross-resistance between DDT and lambda-cyhalothrin in the A. aegypti populations tested was dismissed. Physiological resistance to lambdacyhalothrin appears to be associated with increased NSE. The differences in susceptibility levels and enzyme values among the populations were associated with genetic variations and chemicals in use locally. [ABSTRACT FROM AUTHOR]

This article discusses the main features of the national health research systems (NHRS) of Argentina, Bolivia, Brazil, Chile, Costa Rica, Cuba, Ecuador, El Salvador, Honduras, Panama, Paraguay, Peru, Uruguay, and Venezuela, based on documents prepared by their country experts who participated in the First Latin American Conference on Research and Innovation for Health held in April 2008, in Rio de Janeiro, Brazil. The review also includes sources cited in the reports, published scientific papers, and expert opinion, as well as regional secondary sources. Six countries reported having formal entities for health research governance and management: Brazil and Costa Rica's entities are led by their ministries of health; while Argentina, Cuba, Ecuador, and Venezuela have entities shared by their ministries of health and ministries of science and technology. Brazil and Ecuador each reported having a comprehensive national policy devoted specifically to health science, technology, and innovation. Argentina, Brazil, Costa Rica, Cuba, Ecuador, Panama, Paraguay, Peru, and Venezuela reported having established health research priorities. In conclusion, encouraging progress has been made, despite the structural and functional heterogeneity of the study countries' NHRS and their disparate levels of development. Instituting good NHRS governance/management is of utmost importance to how efficiently ministries of health, other government players, and society-at-large can tackle health research.

OBJECTIVE: To identify validated information available on the relationship between social capital (SC) and health in Latin America and the Caribbean (LAC). METHODS: A systematic search for papers published from January 1990-June 2007 was conducted on the Medline, SciELO, LILACS, and the Cochrane Library databases. All of the research and review articles published by scientific journals that evaluated CS and its relationship to health in LAC were included in the analysis. RESULTS: Fifteen articles were found (11 original research and 4 reviews). The health topics examined by the research articles were: (a) mortality and life expectancy, (b) mental health, (c) injuries, (d) nutritional status, and (e) immunization. The validity of these works, the results, and the principal conclusions were analyzed in depth. CONCLUSIONS: Despite limitations inherent to the CS concept and the studies identified, it was confirmed that scientific evidence exists to support the possible association between CS and health in LAC. CS could play a protective role in certain health areas, such as injury prevention and mental health; not withstanding, the relationship between CS and health could vary according to CS subtype and socioeconomic context and culture. It is therefore imperative to continue social epidemiology research that thoroughly investigates the relationship between social determinants and specific aspects of health in LAC context.

The establishment of environmental health indicators for assessing the adverse effects of environmental changes on the population's health and quality of life is, as yet, a goal that has not been fully reached in Latin America and the Caribbean. As such, the United Nations Environment Program and the Pan American Health Organization (PAHO) have convened Region's institutions and experts to develop a comprehensive method for assessing environmental health. This paper evaluates several methodologies, comprehensive or otherwise, for assessing health and the environment, and describes the frameworks that have historically undergirded the key methods that have either structured or generated the environmental health indicators being used in Latin America and the Caribbean. The recurring, methodological limitations were identified: (a) relying heavily on secondary data, which points out the need for technological infrastructure that is rarely available in Latin America and the Caribbean today; and (b) a lack of clear criteria for developing inclusive tools that would facilitate the discussion of environmental health issues at the grass-roots level. Despite the progress made by the field of environmental health with regard to understanding its interdisciplinary complexities, intersectoral operations must be improved to favor open communication and implementation of integrated policies on environmental and health.

Mortality statistics are used in epidemiology and public health as an indicator of health status, to evaluate health programs, and in population studies to compare trends and spatial differences. One of the variables used in this type of analysis is the underlying cause-of-death. However, the quality of cause-of-death statistics based on the information recorded by physicians in death certificates has been criticized. The aim of this paper is to discuss the reliability of cause-of-death data recorded by physicians in death certificates, based on studies carried out according to various methodologies, and to comment on the validity of using such underlying cause-of-death statistics.

OBJECTIVES: To determine the prevalence of Trypanasoma cruzi antibodies among the population under 18 years of age in the state of Veracruz, Mexico, and to identify risk factors associated with housing conditions and vector presence and distribution. METHODS: A cross-sectional, epidemiological study of the population under 18 years of age living in 10 of the 11 health districts of the state of Veracruz, Mexico, from 2000 to2001. Presence of T. cruzi antibodies was determined by hemagglutination inhibition test (HAI) and enzyme-linked immunosorbent assays (ELISA) of serum samples spotted on filter paper, and confirmed by HAI, ELISA, and indirect immunofluorescence assay (IFA) on serum samples. A questionnaire was administered to determined housing conditions, and entomological indices for triatomines were calculated for both the intra- and peridomiciliary areas. The results were analyzed using bifactorial and multifactorial unconditional logistic regression. RESULTS: Of the 150 individuals presenting an initial reaction, 14 were confirmed positive (5 by HAI, ELISA and IFA; 6 by HAI and ELISA, and 3 by ELISA and IFA), for a total prevalence rate of 0.91% (95% CI: 0.85-0.94). All of the confirmed-positive cases were from five of 14 health districts, with the Tuxpan district having the highest prevalence rate: 5.2% (95%CI: 1.2-9.0). Risk factors included having noticed cracks in the house walls and gaps in the roof. The only species of vector captured was Triatoma dimidiata. The entomologic indices for infestation, colonization, and natural infection were: 10.9%, 50.0%, and 9.0%, respectively. CONCLUSIONS: Active, vector-borne transmission of T. cruzi was confirmed in the state of Veracruz, Mexico, with an overall antibody seroprevalence rate of 0.19% among the population under 18 years of age. Seroprevalence rates among this segment of the population, which serves as a sentinel group, should be closely monitored to determine if more stringent methods of vector control and epidemiological surveillance are needed.

At the 2003 meeting of the Directing Council of the Pan American Health Organization (PAHO), the PAHO Member States issued a mandate to strengthen primary health care (Resolution CD44. R6). The mandate led in 2005 to the document 'Renewing Primary Health Care in the Americas. A Position Paper of the Pan American Health Organization/WHO [World Health Organization],' and it culminated in the Declaration of Montevideo, an agreement among the governments of the Region of the Americas to renew their commitment to primary health care (PHC). Scientific data have shown that PHC, regarded as the basis of all the health systems in the Region, is a key component of effective health systems and can be adapted to the range of diverse social, cultural, and economic conditions that exist. The new, global health paradigm has given rise to changes in the population's health care needs. Health services and systems must adapt to address these changes. Building on the legacy of the International Conference on Primary Health Care, held in 1978 in Alma-Ata (Kazakhstan, Union of Soviet Socialist Republics), PAHO proposes a group of strategies critical to adopting PHC-based health care systems based on the principles of equity, solidarity, and the right to the highest possible standard of health. The main objective of the strategies is to develop and/or strengthen PHC-based health systems in the entire Region of the Americas. A substantial effort will be required on the part of health professionals, citizens, governments, associations, and agencies. This document explains the strategies that must be employed at the national, subregional, Regional, and global levels. [ABSTRACT FROM AUTHOR]

During the last 22 years, the Region of the Americas has seen an upward trend in dengue incidence, with epidemics peaking ever higher and recurring every 3-5 years, almost regularly. A major factor in the spread of the disease has been the diminished capacity of national programs to respond with dengue prevention and control. This paper evaluates the Integrated Strategy for Dengue Prevention and Control-approved by the 44th Directing Council of the Pan American Health Organization in September 2003- and its preliminary results. The Integrated Strategy for Dengue is a management model designed to strengthen national programs, with a focus on reducing morbidity, mortality, and the societal and economic burdens produced by outbreaks and epidemics. Currently, 11 of the countries in the Region have developed a plan for or implemented a national strategy. In addition, a sub-Regional plan has been developed for Central America and the Dominican Republic. The Integrated Strategy for Dengue is expected to produce a qualitative leap forward in prevention and control through stronger partnerships among the State, its various ministries, and governing bodies, at all levels; private companies; and the range of community and civil groups. Once implemented, this strategy will reduce risk factors for dengue transmission, establish an integrated epidemiological surveillance system, decrease Aedes aegypti mosquito populations, prepare laboratories to better detect and identify the virus, optimize diagnosis and treatment, and, as a result, decrease the frequency, magnitude, and severity of dengue outbreaks and epidemics.

This paper, which focuses on the Brazilian Ministry of Health's agenda as the national health authority between 1990 and 2002, identifies and analyzes Ministry priorities. Three ,lain policies were identified for the period: decentralization, establishment of a family health program, and the policy to combat AIDS. In general, the initial design of these policies was consistent with the guidelines of the Brazilian public health system (SUS). Howitzer, discrepancies were found between the universalistic agenda of the Brazilian health reform carried out in the 1980s and the hegemonic agenda of state reform that prevailed in the country in the 1990s, which had liberal roots and did not favor the expansion of government actions and comprehensive social policies. Within this unfavorable political and economic context, the development of specific health policies prioritized by the Brazilian Ministry of Health revealed unsolved problems and gaps in the public health system and limitations in the Ministry's ability to exercise its role as national health authority.

The objective of this paper is to present and discuss Brazilian policy concerning actions to protect breastfeeding, especially the history, international and national background, limitations, and perspectives of the Brazilian Guidelines for the Marketing of Baby Food, Pacifiers and Bottles. The Brazilian Guidelines, which play a crucial role in protecting breastfeeding against industry marketing strategies, were based on the International Code of Marketing of Breastmilk Substitutes, proposed by the World Health Organization in 1981. The first version of the Brazilian Guidelines was released in 1988, and there were subsequent revisions in 1992 and 2001/2002. In 2006, the Guidelines became national law. However, the strides made over this period in terms of regulation have been few because the law is not always observed. Thus, it is essential that all actors involved, including government officials, manufacturers and sellers of baby food and other baby products, teaching and health professionals and their associations, international bodies, and non-governmental organizations make a commitment to enforce the current law.

Over the past 10 years, the American Region has witnessed the reintroduction and dissemination of dengue virus serotype 3. In this paper we describe the main clinical and epidemiologic features of the dengue 3 epidemic that broke out in Cuba between June 2001 and March 2002, as well as the measures that were undertaken to eliminate it. A total of 14 524 confirmed cases were reported, 12 889 (88,7%) of them in the City of Havana. Eighty-one cases of dengue hemorrhagic fever were confirmed, three of which died. Secondary infection, white skin color, sickle cell anemia, and bronchial asthma were risk factors for dengue hemorrhagic fever. Active clinical and epidemiologic surveillance and laboratory support were critical to the early detection of transmission and to the monitoring of the epidemic. Widespread involvement of the community and its different sectors, participation of the mass media with a single leadership in command, and strong political will were the key factors that made it possible to eliminate transmission. This epidemic was one more example of the risk of dengue epidemics faced by countries in the area, including those that have strong surveillance and control programs. It also served to show that by applying the principles established by the Pan American Health Organization and the World Health Organization for dengue control, transmission can be stopped.

INTRODUCTION: Type b Haemophilus influenzae (Hib) continues to be an important causative agent of various infectious processes, and its encapsulated strains cause invasive disease. In some aboriginal populations, the incidence of Hib infections in children under five is greater than 400 per 100,000. In the seventies and eighties, vaccines against Hib were developed after antibodies against the capsular component were identified. The objective of this paper was to estimate the impact that the vaccine against Hib has had in Brazil's Federal District since it was introduced in March of 1998. METHODS: Using population-based data obtained from Brazil's Federal District's Ministry of Health's Surveillance System, rates of incidence of meningitis during the three years that preceded and that followed the introduction of the anti-Hib vaccine were compared. Comparisons were also drawn between changes in the trends observed. RESULTS: A comparison of the data from the two periods showed a decrease of approximately 90% in the incidence of Hib meningitis, but no concomitant decrease in other forms of bacterial meningitis was noted. There was also a proportional increase in the number of cases among infants 6 months of age and under due to a drop in the incidence of the disease in children older than 6 months. CONCLUSION: As a result of the introduction of the conjugated anti-Hib vaccine in Brazil's Federal District, the incidence of Hib meningitis among children 7 months to 35 months of age dropped from 168 per 100,000 to 15 per 100,000 (91.1%).

OBJECTIVE: The objective of this paper is to describe HIV prevention programs conducted by nongovernmental organizations (NGO) that are meeting this challenge. METHODS: One NGO undertaking HIV prevention programs was evaluated in each of the 23 countries participating in the Global AIDS Intervention Network (GAIN) Project throughout Latin America and the Caribbean. A two-stage selection process was used: (1) a search in databases and other information sources; (2) identification of NGOs that were best established and most actively engaged in HIV prevention activity. Executive directors were questioned about staffing, budget issues, populations served and barriers faced by these entities. RESULTS: The 23 NGOs conducted 58 direct-service programs and had been conducting HIV prevention activities for a mean of 8 years (SD=4.45; range 1-18 years). Average annual program budget was US $205,393 (range: US $10,000 to US $1,440,000). The NGOs reported a mean of 4.5 full-time employees (range 0-15, SD=4.7). Many relied on volunteers (median=10, mean=51, range 0-700, SD=150) to conduct HIV prevention activities. The NGOs provided prevention services for the general community (82.6%), children and adolescents (34.8%) and men who have sex with men (30.4%). Activities conducted by NGOs included train-the-trainer activities (43.5%) and face-to-face prevention activities (34.8%). Obstacles cited included lack of funding (60.9%) and HIV-related stigma and discrimination (56.5%). CONCLUSION: The strategies used by NGOs to overcome barriers to prevention are a testament to their ingenuity and commitment, and serve as examples for NGOs in other world regions.
