Epidemia de intoxicación por plomo: su atención desde las normas oficiales mexicanas para proteger la salud de la población.

El daño por plomo a la salud poblacional no es el saturnismo, sino la intoxicación crónica a dosis bajas. Aunque la máxima en toxicología de "a mayor dosis, mayor el efecto" aplica al plomo, enfocarse en prevenir exposiciones bajas o moderadas es más relevante para la salud pública. Esta es la paradoja de la prevención de la intoxicación con plomo: la gran mayoría de las personas tiene concentraciones relativamente bajas de plomo en sangre, pero al no haberse identificado un umbral por debajo del cual el plomo en sangre no dañe la salud, es en estos casos en donde más se concentra la carga total de la enfermedad atribuible al plomo. En México, la intoxicación con plomo ha sido una epidemia silenciosa: en 2019 resultó en la pérdida de más de 245 000 años de vida saludable.

The impact of Hurricane Maria on individuals living with non-communicable disease in Puerto Rico: the experience of 10 communities.

BACKGROUND: Coinciding with the rising non-communicable disease (NCD) prevalence worldwide is the increasing frequency and severity of natural hazards. Protecting populations with NCDs against natural hazards is ever more pressing given their increased risk of morbidity and mortality in disaster contexts. This investigation examined Hurricane Maria's impacts across ten lower SES municipalities in Puerto Rico with varying community characteristics and hurricane impacts to understand experiences of supporting individuals with NCD management in the six-month period following the hurricane. METHODS: We conducted 40 qualitative interviews with mayors, first responders, faith leaders, community leaders, and municipal employees from 10 municipalities in Puerto Rico. Using QSR NVivo software, we deductively and inductively coded interview transcripts and undertook thematic analysis to characterize community-level hurricane impact and consequences for NCD management, and to identify convergent and divergent themes. RESULTS: Damages to infrastructure, including healthcare facilities and roadways, complicated the provision of timely health care for NCDs, patient transport, and pharmaceutical/medical supply chain continuity. Lengthy power outages at both healthcare facilities and private residences were barriers to healthcare service delivery, use of medical equipment, and storage of prescription medications with refrigeration, and led to a widespread mental health crisis. Cascading failures such as fuel shortages further compounded these challenges. The consequences of these impacts included the reported exacerbation of health conditions and loss of life among NCD patients. CONCLUSIONS: Study findings identify contributors to morbidity and mortality among individuals with NCDs following Hurricane Maria. With the growing frequency of catastrophic disasters from natural hazards, the experiences of communities that endured these impacts offer important lessons regarding policies and practices to better support community disaster resilience and address the evolving preparedness needs of NCD patients.

Desarrollo de la capacidad para la regulación en salud en México.

La Academia Nacional de Medicina es un espacio esencial para discutir la ciencia de la regulación en salud y posicionar su impacto en la salud y la economía. Enmarcada dentro de la función rectora de la autoridad sanitaria, la regulación en salud es la acción de proteger a la población de los peligros sanitarios involuntarios contra los cuales el individuo no puede protegerse; es una función esencial de la salud pública, componente institucional del sistema de salud y, por ende, vinculada a sus reformas y a la cobertura universal. La regulación tiene sustento en un cuerpo teórico epidemiológico, organizacional, legal, sociológico y económico. Tiene un cuerpo metodológico que sustenta su proceso en el análisis de riesgos y se traduce en normas, implementaciones, cumplimiento, monitoreo y evaluación de la regulación. Tiene una arquitectura profesional, financiera, organizacional, legal y de gobernanza. Dada su acción universal tiene un impacto generalizado en la población y un sustancial efecto económico, influyendo en al menos 17 % del comercio internacional regional. La salud a través de sus autoridades regulatorias debe ser parte del dialogo comercial internacional.The National Academy of Medicine is an essential space to discuss regulatory science in health, and to position its impact on health and economy. Framed within the stewardship role of the health authority, health regulation is the action of protecting the population against involuntary health hazards against which the individual cannot protect him/herself. It is an essential function of public health, an institutional component of the health system and, therefore, linked to its reforms and to universal coverage. Regulation has its support on an epidemiological, organizational, legal, sociological and economic theoretical body. It has a methodological body that supports its regulatory process based on risk analysis and that is translated into regulations, implementations, compliance, monitoring and evaluation of the regulation. It has a professional, financial, organizational, legal and governance architecture. Given its universal action, it has a widespread impact on the population and a substantial economic effect, influencing on at least 17% of regional international trade. Health through its regulatory authorities should be an early part of international trade discussions.

[Regulatory elements on marijuana, for the effective population health protection]. / Elementos regulatorios sobre la marihuana, a consideración para la efectiva protección a la salud de la población.

When discussing the public health approach to the use of marijuana, the complexity of rigorous regulatory interventions for population protection is omitted. Using the experience of governments where these practices already exist, regulation is introduced as an essential public health function, spelling out seven purposes for controlling marijuana. The technical elements of institutional capacity -including the technical and financial capacity- and of governance that must be covered by any rigorous regulation of its use are detailed below. The difficulty of regulating psychoactive substances is addressed when considering the capacity to control other legal substances manifested with their increased consumption. It is concluded that for an effective regulation of marijuana, the need for strengthening the institutional and governance aspects of the regulatory authority should not be minimized.

Al hablar del abordaje de salud pública al uso de la marihuana se soslaya la complejidad de la protección a la población a través de intervenciones regulatorias rigurosas. Considerando la experiencia de gobiernos donde ya existen estas prácticas, se introduce la regulación como una función esencial de la salud pública, haciendo explícitos siete propósitos para el control de la marihuana. Se detallan luego los elementos técnicos, de capacidad institucional (incluyendo la capacidad técnica y financiera) y de gobernanza que deben cumplirse para cualquier regulación rigurosa de su uso. Se señala la dificultad de regular sustancias psicoactivas considerando que la capacidad de control de otras actualmente legales se ha traducido en su creciente consumo. Se expone también que no debe minimizarse la necesidad del fortalecimiento institucional y gobernanza de la autoridad regulatoria para la regulación efectiva de la marihuana.

Health inequalities by gradients of access to water and sanitation between countries in the Americas, 1990 and 2010.

OBJECTIVE: To explore distributional inequality of key health outcomes as determined by access coverage to water and sanitation (WS) between countries in the Region of the Americas. METHODS: An ecological study was designed to explore the magnitude and change-over-time of standard gap and gradient metrics of environmental inequalities in health at the country level in 1990 and 2010 among the 35 countries of the Americas. Access to drinking water and access to improved sanitation facilities were selected as equity stratifiers. Five dependent variables were: total and healthy life expectancies at birth, and infant, under-5, and maternal mortality. RESULTS: Access to WS correlated with survival and mortality, and strong gradients were seen in both 1990 and 2010. Higher WS access corresponded to higher life expectancy and healthy life expectancy and lower infant, under-5, and maternal mortality risks. Burden of life lost was unequally distributed, steadily concentrated among the most environmentally disadvantaged, who carried up to twice the burden than they would if WS were fairly distributed. Population averages in life expectancy and specific mortality improved, but whereas absolute inequalities decreased, relative inequalities remained mostly invariant. CONCLUSIONS: Even with the Region on track to meet MDG 7 on water and sanitation, large environmental gradients and health inequities among countries remain hidden by Regional averages. As the post-2015 development agenda unfolds, policies and actions focused on health equity-mainly on the most socially and environmentally deprived-will be needed in order to secure the right for universal access to water and sanitation.

The association between lead exposure and crime: A systematic review.

Prior research has demonstrated an association between lead exposure and criminal behavior at the population-level, however studies exploring the effect of lead exposure on criminal behavior at the individual-level have not been reviewed systematically. The intent of this study is to complete a systematic review of all studies assessing individual-level exposures to lead and the outcomes of crime and antisocial behavior traits. We included peer reviewed studies that were published prior to August 2022 and were classified as cohort, cross-sectional, or case-control. Studies measuring the outcomes of crime, delinquency, violence, or aggression were included. The following databases were searched using a standardized search strategy: ProQuest Environmental Science Database, PubMed, ToxNet and the Public Affairs Information Service (PAIS). Seventeen manuscripts met our inclusion criteria. Blood lead was measured in 12 studies, bone lead in 3 studies, and dentine lead levels in 2 studies. This systematic review identified a wide range of diverse outcomes between exposure to lead at multiple windows of development and later delinquent, criminal and antisocial behavior. A review of all potential confounding variables included within each study was made, with inclusion of relevant confounders into the risk of bias tool. There is limited data at the individual level on the effects of prenatal, childhood, and adolescent lead exposure and later criminal behavior and more evidence is necessary to evaluate the magnitude of the associations seen in this review. Our review, in conjunction with the available biological evidence, suggests that an excess risk for criminal behavior in adulthood exists when an individual is exposed to lead in utero or in the early years of childhood. The authors report no conflict of interest and no funding source. Clinical trial registration: PROSPERO ID: CRD42021268379.

Total Excess Mortality Surveillance for Real-Time Decision-Making in Disasters and Crises.

Crises such as Hurricane Maria and the coronavirus disease 2019 (COVID-19) pandemic have revealed that untimely reporting of the death toll results in inadequate interventions, impacts communication, and fuels distrust on response agencies. Delays in establishing mortality are due to the contested definition of deaths attributable to a disaster and lack of rapid collection of vital statistics data from inadequate health system infrastructure. Readily available death counts, combined with geographic, demographic, and socioeconomic data, can serve as a baseline to build a continuous mortality surveillance system. In an emergency setting, real-time Total, All-cause, Excess Mortality (TEM) can be a critical tool, granting authorities timely information ensuring a targeted response and reduce disaster impact. TEM measurement can identify spikes in mortality, including geographic disparities and disproportionate deaths in vulnerable populations. This study recommends that measuring total, all-cause, excess mortality as a first line of response should become the global standard for measuring disaster impact.

Toward a research and action agenda on urban planning/design and health equity in cities in low and middle-income countries.

The importance of reestablishing the link between urban planning and public health has been recognized in recent decades; this paper focuses on the relationship between urban planning/design and health equity, especially in cities in low and middle-income countries (LMICs). The physical urban environment can be shaped through various planning and design processes including urban planning, urban design, landscape architecture, infrastructure design, architecture, and transport planning. The resultant urban environment has important impacts on the health of the people who live and work there. Urban planning and design processes can also affect health equity through shaping the extent to which the physical urban environments of different parts of cities facilitate the availability of adequate housing and basic infrastructure, equitable access to the other benefits of urban life, a safe living environment, a healthy natural environment, food security and healthy nutrition, and an urban environment conducive to outdoor physical activity. A new research and action agenda for the urban environment and health equity in LMICs should consist of four main components. We need to better understand intra-urban health inequities in LMICs; we need to better understand how changes in the built environment in LMICs affect health equity; we need to explore ways of successfully planning, designing, and implementing improved health/health equity; and we need to develop evidence-based recommendations for healthy urban planning/design in LMICs.

Resilience of Communities in Puerto Rico Following Hurricane Maria: Community-Based Preparedness and Communication Strategies.

OBJECTIVE: This study aimed to examine factors that may have contributed to community disaster resilience following Hurricane Maria in Puerto Rico. METHODS: In April 2018, qualitative interviews (n = 22) were conducted with stakeholders in 7 Puerto Rican municipalities (9% of total). Transcripts were deductively and inductively coded and analyzed to identify salient topics and themes, then examined according to strategic themes from the Federal Emergency Management Association's (FEMA) Whole Community Approach. RESULTS: Municipal preparedness efforts were coordinated, community-based, leveraged community assets, and prioritized vulnerable populations. Strategies included (1) multi-sectoral coordination and strategic personnel allocation; (2) neighborhood leader designation as support contacts; (3) leveraging of community leader expertise and social networks to protect vulnerable residents; (4) Censuses of at-risk groups, health professionals, and first responders; and (5) outreach for risk communication and locally tailored protective measures. In the context of collapsed telecommunications, communities implemented post-disaster strategies to facilitate communication with the Puerto Rican Government, between local first responders, and to keep residents informed, including the use of: (1) police radios; (2) vehicles with loudspeakers; (3) direct interpersonal communication; and (4) solar-powered Internet radio stations. CONCLUSIONS: Adaptive capacities and actions of Puerto Rican communities exemplify the importance of local solutions in disasters. Expanded research is recommended to better understand contributors to disaster resilience.

The Impact of Natural Hazards on Older Adult Health: Lessons Learned From Hurricane Maria in Puerto Rico.

OBJECTIVE: With natural hazards increasing in frequency and severity and global population aging, preparedness efforts must evolve to address older adults' risks in disasters. This study elucidates potential contributors to the elevated older adult mortality risk following Hurricane Maria in Puerto Rico through an examination of community stakeholder preparedness, response, and recovery experiences. METHODS: In April 2018, qualitative interviews (n = 22) were conducted with stakeholders in 7 Puerto Rican municipalities. Interview transcripts were deductively and inductively coded and analyzed to identify salient topics and themes representing participant response patterns. RESULTS: The hurricane's detrimental impact on older adult health emerged as a prominent finding. Through 6 months post-hurricane, many older adults experienced unmet needs that contributed to declining physical and emotional health, inadequate non-communicable disease management, social isolation, financial strain, and excess morbidity and mortality. These needs were predominantly consequences of lengthy public service gaps, unsafe living conditions, interrupted health care, and the incongruence between preparedness and event severity. CONCLUSIONS: In a landscape of increasing natural hazard frequency and magnitude, a pattern of older adult risk has become increasingly clear. Study findings compel practitioners to engage in natural hazard preparedness planning, research, and policy-making that considers the multiple facets of older adult well-being.

Commercial determinants of health: an ethical exploration.

OBJECTIVES: This paper seeks to contribute toward a better understanding of commercial determinants of health by proposing a set of ethical principles that can be used by researchers and other health actors in understanding and addressing Commercial Determinants of Health (CDoH). METHODS: The paper is mainly based on a systematic review and qualitative analysis of the existing literature on CDoH and public health ethics frameworks. We conducted searches using selected search engines (Google Scholar and Pubmed). For ethical challenges relating to CDOH, our searches in Google Scholar yielded 17 papers that discussed ethical challenges that affect CDoH. For ethical frameworks relevant for CDOH, our searches in Google Scholar and Pubmed yielded 15 papers that clearly described bioethical models including relevant ethical principles. Additionally, we consulted eight experts working on CDoH. Through these two methods, we were able to identify ethical challenges as well as norms and values related to CDoH that we offer as candidates to comprise a foundational ethics framework for CDoH. RESULTS: Discussing risk factors associated with CDH frequently brings public health into conflict with the interests of industry actors in the food, automobile, beverage, alcohol, ammunition, gaming and tobacco industries including conflict between profit-making and public health. We propose the following candidate ethical principles that can be used in addressing CDoH: moral responsibility, nonmaleficence, social justice and equity, consumer sovereignty, evidence-informed actions, responsiveness, accountability, appropriateness, transparency, beneficence and holism. CONCLUSIONS: We hope that this set of guiding principles will generate wider global debate on CDoH and help inform ethical analyses of corporate actions that contribute to ill health and policies aimed at addressing CDoH. These candidate principles can guide researchers and health actors including corporations in addressing CDoH.

Implementation of Mexico's Health Promotion Operational Model.

Mexico is undergoing profound health reform, extending health insurance to previously uninsured populations and changing the way health care services are delivered. Legislation enacted in 2003 and implemented in 2004 mandated funding and infrastructure that will allow 52% of Mexico's population to access medical care at no cost by 2010. This ambitious social reform has not been without challenges, particularly financial sustainability. Health promotion, because of its potential to prevent or delay chronic diseases and injuries and their associated costs, is a key component of health care reform. In 2006, the Ministry of Health's General Directorate of Health Promotion developed the Health Promotion Operational Model. Based on Ottawa Charter functions, the model integrates health promotion activities within the overall health care system. The main goal of this model is to build strong human capital and to improve organizational capacity for health promotion starting at the local level by training health care personnel to implement health promotion activities. Organizational development workshops started in 2006, and implementation plans in all 32 Mexican states were in place by end of 2008.

Differential and persistent risk of excess mortality from Hurricane Maria in Puerto Rico: a time-series analysis.

BACKGROUND: Hurricane Maria struck Puerto Rico on Sept 20, 2017, devastating the island. Controversy surrounded the official death toll, fuelled by estimates of excess mortality from academics and investigative journalists. We analysed all-cause excess mortality following the storm. METHODS: We did a time-series analysis in Puerto Rico from September, 2017, to February, 2018. Mortality data were from the Puerto Rico Vital Statistics System. We developed two counterfactual scenarios to establish the population at risk. In the first scenario, the island's population was assumed to track the most recent census estimates. In the second scenario, we accounted for the large-scale population displacement. Expected mortality was projected for each scenario through over-dispersed log-linear regression from July, 2010, to August, 2017, taking into account changing distributions of age, sex, and municipal socioeconomic development, as well as both long-term and seasonal trends in mortality. Excess mortality was calculated as the difference between observed and expected deaths. FINDINGS: Between September, 2017, and February, 2018, we estimated that 1191 excess deaths (95% CI 836-1544) occurred under the census scenario. Under the preferred displacement scenario, we estimated that 2975 excess deaths (95% CI 2658-3290) occurred during the same observation period. The ratio of observed to expected mortality was highest for individuals living in municipalities with the lowest socioeconomic development (1·43, 95% CI 1·39-1·46), and for men aged 65 years or older (1·33, 95% CI 1·30-1·37). Excess risk persisted in these groups throughout the observation period. INTERPRETATION: Analysis of all-cause mortality with vital registration data allows for unbiased estimation of the impact of disasters associated with natural hazards and is useful for public health surveillance. It does not depend on certified cause of death, the basis for the official death toll in Puerto Rico. Although all sectors of Puerto Rican society were affected, recovery varied by municipal socioeconomic development and age groups. This finding calls for equitable disaster preparedness and response to protect vulnerable populations in disasters.

The present and future of Mexican health promotion.

Mexico, with a 92 percent literacy, 62 native languages and 12.7 million indigenous people, has entered a new era of macroeconomic stability. Nevertheless 40 percent of the population live below the poverty line. The burden of disease includes malnutrition, infectious diseases, reproductive health problems, as well as chronic diseases. Addressing the social determinants of health has been a priority. This can be seen in two of the most successful Mexican programs. The National Healthy Communities Program that uses a setting approach to establish a link between socioeconomic development and health levels and the Opportunities Program that has become an international model and which is a comprehensive, poverty alleviation program that uses education, fiscal measures and health education to improve population health. Both have been implemented throughout all the states in an intersectorial manner, since 1997 and 2000 respectively. Health promotion in Mexico has evolved in many positive ways during the past 20 years. Development of healthy environments and community actions are the strongest components. Evidence and evaluation, health services reorientation, and building personal skills and empowerment are the weakest. The paradox between low empowerment and high community action results in a superficial community participation that lacks a real commitment towards health. The newest Mexican health promotion policy is named National Alliance for Health and it aims to involve all members of society. Its value is to be independent of any international recommendation; its weakness is that it lacks a deep analysis of the health issues that it is supposed to solve. Consequently valid evaluations are not feasible, and without real evidence the impact of these kinds of policies will remain unknown.

Beyond managing healthcare risks: the health-promoting hospital initiative in Mexico.

The hospital industry is unique for having within it "customers" exposed to a complex mix of risks. A model is proposed that combines both the risk assessment and the promoting hospital models. This model acts in three stages: exposure elimination and protection, health aptitudes and culture, and hospital population action, and includes specific operations that can be tracked through specific effectiveness factors. Being tested in a small community hospital, there is an opportunity to apply it within the current Mexican Health reform that moves the financial risk from the patient to the provider and thus may support health promotion.

Motor alterations associated with exposure to manganese in the environment in Mexico.

Overexposure to manganese (Mn) causes neurotoxicity (a Parkinson-like syndrome) or psychiatric damage ("manganese madness"). Several studies have shown alterations to motor and neural behavior associated with exposure to Mn in the workplace. However, there are few studies on the effects of environmental exposure of whole populations. We studied the risk of motor alterations in people living in a mining district in Mexico. We studied 288 individual people (168 women and 120 men) from eight communities at various distances from manganese extraction or processing facilities in the district of Molango. We measured manganese concentrations in airborne particles, water, soil and crops and evaluated the possible routes of Mn exposure. We also took samples of people's blood and determined their concentrations of Mn and lead (Pb). We used "Esquema de Diagnóstico Neuropsicológico" Ardila and Ostrosky-Solís's neuropsychological battery to evaluate motor functions. Concentrations of Mn in drinking water and maize grain were less than detection limits at most sampling sites. Manganese extractable by DTPA in soils ranged between 6 and 280 mg kg(-1) and means were largest close to Mn extraction or processing facilities. Air Mn concentration ranged between 0.003 and 5.86 microg/m(3); the mean value was 0.42 microg/m(3) and median was 0.10 microg/m(3), the average value (geometric mean) resulted to be 0.13 microg/m(3). Mean blood manganese concentration was 10.16 microg/l, and geometric mean 9.44 microg/l, ranged between 5.0 and 31.0 mcrog/l. We found no association between concentrations of Mn in blood and motor tests. There was a statistically significant association between Mn concentrations in air and motor tests that assessed the coordination of two movements (OR 3.69; 95% CI 0.9, 15.13) and position changes in hand movements (OR 3.09; CI 95% 1.07, 8.92). An association with tests evaluating conflictive reactions (task that explores verbal regulations of movements) was also found (OR 2.30; CI 95% 1.00, 5.28). It seems from our results that people living close to the manganese mines and processing plants suffer from an incipient motor deficit, as a result of their inhaling manganese-rich dust.

Mapping national capacity to engage in health promotion: overview of issues and approaches.

This paper reviews approaches to the mapping of resources needed to engage in health promotion at the country level. There is not a single way, or a best way to make a capacity map, since it should speak to the needs of its users as they define their needs. Health promotion capacity mapping is therefore approached in various ways. At the national level, the objective is usually to learn the extent to which essential policies, institutions, programmes and practices are in place to guide recommendations about what remedial measures are desirable. In Europe, capacity mapping has been undertaken at the national level by the WHO for a decade. A complimentary capacity mapping approach, HP-Source.net, has been undertaken since 2000 by a consortium of European organizations including the EC, WHO, International Union for Health Promotion and Education, Health Development Agency (of England) and various European university research centres. The European approach emphasizes the need for multi-methods and the principle of triangulation. In North America, Canadian approaches have included large- and small-scale international collaborations to map capacity for sustainable development. US efforts include state-level mapping of capacity to prevent chronic diseases and reduce risk factor levels. In Australia, two decades of mapping national health promotion capacity began with systems needed by the health sector to design and deliver effective, efficient health promotion, and has now expanded to include community-level capacity and policy review. In Korea and Japan, capacity mapping is newly developing in collaboration with European efforts, illustrating the usefulness of international health promotion networks. Mapping capacity for health promotion is a practical and vital aspect of developing capacity for health promotion. The new context for health promotion contains both old and new challenges, but also new opportunities. A large scale, highly collaborative approach to capacity mapping is possible today due to developments in communication technology and the spread of international networks of health promoters. However, in capacity mapping, local variation will always be important, to fit variation in local contexts.
