The effect of conditional cash transfers on tuberculosis incidence and mortality is determined by ethnoracial and socioeconomic factors: a cohort study of 54 million individuals in Brazil.

Background: Conditional Cash Transfers (CCT) are the world's most widely implemented interventions for poverty alleviation. Still, there is no solid evidence of the CCT effects on the reduction of the burden of Tuberculosis (TB) in marginalized and extremely vulnerable populations. We estimated the effect of the Bolsa Família Program (BFP), the largest CCT in the world, on TB incidence, mortality, and case-fatality rate using a nationwide cohort of 54.5 million individuals during a 12-year period in Brazil. Methods: We selected low-income individuals who entered in the 100 Million Brazilians Cohort and were linked to nationwide TB registries between 2004 to 2015, and compared BFP beneficiaries and non-beneficiaries using a quasi-experimental impact evaluation design. We employed inverse probability of treatment weighting (IPTW) multivariable Poisson regressions, adjusted for all relevant socioeconomic, demographic, and healthcare confounding variables - at individual and municipal level. Subsequently, we evaluated BFP effects for different subpopulations according to ethnoracial factors, wealth levels, sex, and age. We also performed several sensitivity and triangulation analyses to verify the robustness of the estimates. Findings: Exposure to BFP was associated with a large reduction in TB incidence in the low-income individuals under study (adjusted rate ratio [aRR]:0.59;95%CI:0.58-0.60) and mortality (aRR:0.69;95%CI:0.65-0.73). The strongest BFP effect was observed in Indigenous people both for TB incidence (aRR:0.37;95%CI:0.32-0.42), and mortality-aRR:0.35;95%CI:0.20-0.62), and in Black and Pardo people (Incidence-aRR:0.58;95%CI:0.57-0.59; Mortality -aRR:0.69;95%CI:0,64-0,73). BFP effects showed a clear gradient according to wealth levels and were considerably stronger among the extremely poor individuals for TB incidence (aRR:0.49, 95%CI:0.49-0.50) and mortality (aRR:0.60;95%CI:0.55-0.65). The BFP effects on case-fatality rates were also positive, however without statistical significance. Interpretation: CCT can strongly reduce TB incidence and mortality in extremely poor, Indigenous, Black and Pardo populations, and could significantly contribute to achieving the End TB Strategy targets and the TB-related Sustainable Development Goals.

Can primary health care mitigate the effects of economic crises on child health in Latin America? An integrated multicountry evaluation and forecasting analysis.

BACKGROUND: Latin American and Caribbean countries are dealing with the combined challenges of pandemic-induced socicoeconomic stress and increasing public debt, potentially leading to reductions in welfare and health-care services, including primary care. We aimed to evaluate the impact of primary health-care coverage on child mortality in Latin America over the past two decades and to forecast the potential effects of primary health-care mitigation during the current economic crisis. METHODS: This multicountry study integrated retrospective impact evaluations in Brazil, Colombia, Ecuador, and Mexico from 2000 to 2019 with forecasting models covering up to 2030. We estimated the impact of coverage of primary health care on mortality rates in children younger than 5 years (hereafter referred to as under-5 mortality) across different age groups and causes of death, adjusting for all relevant demographic, socioeconomic, and health-care factors, with fixed-effects multivariable negative binomial models in 5647 municipalities with an adequate quality of vital statistics. We also performed several sensitivity and triangulation analyses. We integrated previous longitudinal datasets with validated dynamic microsimulation models and projected trends in under-5 mortality rates under alternative policy response scenarios until 2030. FINDINGS: High primary health-care coverage was associated with substantial reductions in post-neonatal mortality rates (rate ratio [RR] 0·72, 95% CI 0·71-0·74), toddler (ie, aged between 1 year and <5 years) mortality rates (0·75, 0·73-0·76), and under-5 mortality rates (0·81, 0·80-0·82), preventing 305 890 (95% CI 251 826-360 517) deaths of children younger than 5 years over the period 2000-19. High primary health-care coverage was also associated with lower under-5 mortality rates from nutritional deficiencies (RR 0·55, 95% CI 0·52-0·58), anaemia (0·64, 0·57-0·72), vaccine-preventable and vaccine-sensitive conditions (0·70, 0·68-0·72), and infectious gastroenteritis (0·78, 0·73-0·84). Considering a scenario of moderate economic crisis, a mitigation response strategy implemented in the period 2020-30 that increases primary health-care coverage could reduce the under-5 mortality rate by up to 23% (RR 0·77, 95% CI 0·72-0·84) when compared with a fiscal austerity response, and this strategy would avoid 142 285 (95% CI 120 217-164 378) child deaths by 2030 in Brazil, Colombia, Ecuador, and Mexico. INTERPRETATION: The improvement in primary health-care coverage in Brazil, Colombia, Ecuador, and Mexico over the past two decades has substantially contributed to improving child survival. Expansion of primary health-care coverage should be considered an effective strategy to mitigate the health effects of the current economic crisis and to achieve Sustainable Development Goals related to child health.

Current and Projected Mortality and Hospitalization Rates Associated With Conditional Cash Transfer, Social Pension, and Primary Health Care Programs in Brazil, 2000-2030.

Importance: The health outcomes of increased poverty and inequalities in low- and middle-income countries (LMICs) have been substantially amplified as a consequence of converging multiple crises. Brazil has some of the world's largest conditional cash transfer (Programa Bolsa Família [PBF]), social pension (Beneficio de Prestacão Continuada [BPC]), and primary health care (Estratégia de Saúde da Família [ESF]) programs that could act as mitigating interventions during the current polycrisis era of increasing poverty, slow or contracting economic growth, and conflicts. Objective: To evaluate the combined association of the Brazilian conditional cash transfer, social pension, and primary health care programs with the reduction of morbidity and mortality over the last 2 decades and forecast their potential mitigation of the current global polycrisis and beyond. Design, Setting, and Participants: This cohort study used a longitudinal ecological design with multivariable negative binomial regression models (adjusted for relevant socioeconomic, demographic, and health care variables) integrating the retrospective analysis from 2000 to 2019, with dynamic microsimulation models to forecast potential child mortality scenarios up to 2030. Participants included a cohort of 2548 Brazilian municipalities from 2004 to 2019, projected from 2020 to 2030. Data analysis was performed from September 2022 to February 2023. Exposure: PBF coverage of the target population (those who were poorest) was categorized into 4 levels: low (0%-29.9%), intermediate (30.0%-69.9%), high (70.0%-99.9%), and consolidated (≥100%). ESF coverage was categorized as null (0), low (0.1%-29.9%), intermediate (30.0%-69.9%), and consolidated (70.0%-100%). BPC coverage was categorized by terciles. Main outcomes and measures: Age-standardized, all-cause mortality and hospitalization rates calculated for the entire population and by age group (<5 years, 5-29 years, 30-69 years, and ≥70 years). Results: Among the 2548 Brazilian municipalities studied from 2004 to 2019, the mean (SD) age-standardized mortality rate decreased by 16.64% (from 6.73 [1.14] to 5.61 [0.94] deaths per 1000 population). Consolidated coverages of social welfare programs studied were all associated with reductions in overall mortality rates (PBF: rate ratio [RR], 0.95 [95% CI, 0.94-0.96]; ESF: RR, 0.93 [95% CI, 0.93-0.94]; BPC: RR, 0.91 [95% CI, 0.91-0.92]), having all together prevented an estimated 1 462 626 (95% CI, 1 332 128-1 596 924) deaths over the period 2004 to 2019. The results were higher on mortality for the group younger than age 5 years (PBF: RR, 0.87 [95% CI, 0.85-0.90]; ESF: RR, 0.89 [95% CI, 0.87-0.93]; BPC: RR, 0.84 [95% CI, 0.82-0.86]), on mortality for the group aged 70 years and older, and on hospitalizations. Considering a shorter scenario of economic crisis, a mitigation strategy that will increase the coverage of PBF, BPC, and ESF to proportionally cover the newly poor and at-risk individuals was projected to avert 1 305 359 (95% CI, 1 163 659-1 449 256) deaths and 6 593 224 (95% CI, 5 534 591-7 651 327) hospitalizations up to 2030, compared with fiscal austerity scenarios that would reduce the coverage of these interventions. Conclusions and relevance: This cohort study's results suggest that combined expansion of conditional cash transfers, social pensions, and primary health care should be considered a viable strategy to mitigate the adverse health outcomes of the current global polycrisis in LMICs, whereas the implementation of fiscal austerity measures could result in large numbers of preventable deaths.

Evolución clínica y nutricional de pacientes sometidos a cirugía bariátrica en un hospital de referencia del estado de Pernambuco / Evolução clínica e nutricional de pacientes submetidos à cirurgia bariátrica em um hospital de referência do estado de Pernambuco / Clinical and nutritional evolution of patients undergoing bariatric surgery in a reference hospital in the state of Pernambuco

La obesidad es un factor de riesgo para enfermedades crónicas no transmisibles como Diabetes Mellitus 2, Hipertensión Arterial Sistémica, entre otras. La gastroplastia se encuentra entre las alternativas terapéuticas con buena respuesta a la pérdida de peso cuando el ejercicio físico y la dieta no fueron eficientes, resultando en un mejor control clínico de las comorbilidades asociadas. Por tanto, analizar la evolución clínica y nutricional de pacientes sometidos a cirugía bariátrica, 12 meses después del procedimiento, con el fin de observar los impactos de esta terapia. Se realizó una serie de casos, que incluyeron individuos sometidos a cirugía bariátrica y que presentaban alguna comorbilidad asociada al exceso de peso. La recolección de datos se realizó en Instituto de Medicina Integral Prof. Fernando Figueira – IMIP, ubicado en la ciudad de Recife-Pernambuco, período de mayo de 2021 a octubre de 2021. Se obtuvieron datos antropométricos, clínicos y bioquímicos. Se incluyeron en el estudio cuarenta personas con una edad media de 43 ± 11,7 años, siendo la técnica quirúrgica más utilizada el Bypass Gástrico (77,5%). Se observó una reducción de la Hemoglobina Glicada de 5,8% ± 0,5 en el preoperatorio a 5,1% ± 0,2 a los 12 meses (p = <0,001), y una reducción del Colesterol Total de 199,0 mg/dL a 167,0 mg/dL (p = <0,001) antes y 12 meses después de la gastroplastia, respectivamente. Además de estas, observamos una mejora estadísticamente significativa en todas las variables antropométricas y bioquímicas analizadas, excepto la glucemia en ayunas. Estos resultados pueden explicarse por cambios en la secreción de hormonas intestinales, que ayudan a mejorar el control de la glucosa, los lípidos y la presión arterial, además de la pérdida de peso. Por tanto, la cirugía bariátrica parece tener un impacto positivo en la evolución bioquímica y antropométrica en el primer año tras la cirugía.(AU)

Introduction: Obesity is a risk factor for chronic non-com-municable diseases such as Type 2 Diabetes Mellitus, SystemicArterial Hypertension, dyslipidemia, among others. Gastroplast is among the therapeutic alternatives with a good response toweight loss when physical exercise and diet were not efficient,resulting in better clinical control of associated comorbidities. Therefore, analyze the clinical and nutritional evolution of pa-tients undergoing bariatric surgery in a reference hospital in thestate of Pernambuco, 12 months after the procedure, in orderto observe the impacts of this therapy. Material and methods: A series of cases was carried out,which included individuals who underwent bariatric surgeryand who had some comorbidity associated with excessweight. Data collection was carried out at the nutrition out-patient clinic of the Instituto de Medicina Integral Prof.Fernando Figueira – IMIP, located in the city of Recife-Pernambuco, period from May 2021 to October 2021.Anthropometric, clinical and biochemical data were obtained. Results: 40 individuals were included in the study with amean age of 43 ± 11.7 years, with a predominance of fema-les (92.5%), with the most common surgical technique beingGastric Bypass (77.5%). A reduction in Glycated Hemoglobinwas observed from 5.8% ± 0.5 in the preoperative period to5.1% ± 0.2 at 12 months (p = <0.001), and a reduction inTotal Cholesterol from 199.0mg/dL to 167.0mg/dL (p =<0.001) before and 12 months after gastroplasty, respecti-vely. In addition to these, we observed a statistically signifi-cant improvement in all anthropometric and biochemical va-riables analyzed, except fasting blood glucose. Discussion: These results can be explained based onchanges in the secretion of intestinal hormones, which helpwith better glucose, lipid and blood pressure control, in addi-tion to weight loss...(AU)

The combined effect of social pensions and cash transfers on child mortality: evaluating the last two decades in Brazil and projecting their mitigating effect during the global economic crisis.

Background: The world is currently experiencing multiple economic crises due to the COVID-19 pandemic, war in Ukraine, and inflation surge, which disproportionately affect children, especially in low- and middle-income countries (LMICs). We evaluated if the expansion of Social Assistance, represented by Social Pensions (SP) and Conditional Cash Transfers (CCT), could reduce infant and child mortality, and mitigate excess deaths among children in Brazil, one of the LMICs most affected by these economic crises. Methods: We conducted a retrospective impact evaluation in a cohort of Brazilian municipalities from 2004 to 2019 using multivariable fixed-effects negative binomial models, adjusted for relevant demographic, social, and economic factors, to estimate the effects of the SP and CCT on infant and child mortality. To verify the robustness of the results, we conducted several sensitivity and triangulation analyses, including difference-in-difference with propensity-score matching. These results were incorporated into dynamic microsimulation models to generate projections to 2030 of various economic crises and Social Assistance scenarios. Findings: Consolidated coverage of SP was associated with significant reductions in infant and child mortality rates, with a rate ratio (RR) of 0.843 (95% CI: 0.826-0.861) and 0.840 (95% CI: 0.824-0.856), respectively. Similarly, CCT consolidated coverages showed RRs of 0.868 (95% CI: 0.842-0.849) and 0.874 (95% CI: 0.850-0.899) for infant and child mortality, respectively. The higher the degree of poverty in the municipalities, the stronger the impact of CCT on reducing child mortality. Given the current economic crisis, a mitigation strategy that will increase the coverage of SP and CCT could avert 148,736 (95% CI: 127,148-170,706) child deaths up to 2030, compared with fiscal austerity measures. Interpretation: SP and CCT programs could strongly reduce child mortality in LMICs, and their expansion should be considered as an effective strategy to mitigate the impact of the current multiple global economic crises.

Understanding the social determinants of child mortality in Latin America over the last two decades: a machine learning approach.

The reduction of child mortality rates remains a significant global public health challenge, particularly in regions with high levels of inequality such as Latin America. We used machine learning (ML) algorithms to explore the relationship between social determinants and child under-5 mortality rates (U5MR) in Brazil, Ecuador, and Mexico over two decades. We created a municipal-level cohort from 2000 to 2019 and trained a random forest model (RF) to estimate the relative importance of social determinants in predicting U5MR. We conducted a sensitivity analysis training two more ML models and presenting the mean square error, root mean square error, and median absolute deviation. Our findings indicate that poverty, illiteracy, and the Gini index were the most important variables for predicting U5MR according to the RF. Furthermore, non-linear relationships were found mainly for Gini index and U5MR. Our study suggests that long-term public policies to reduce U5MR in Latin America should focus on reducing poverty, illiteracy, and socioeconomic inequalities. This research provides important insights into the relationships between social determinants and child mortality rates in Latin America. The use of ML algorithms, combined with large longitudinal data, allowed us to evaluate the effects of social determinants on health more carefully than traditional models.

Evaluation and Forecasting Analysis of the Association of Conditional Cash Transfer With Child Mortality in Latin America, 2000-2030.

Importance: Latin America has implemented the world's largest and most consolidated conditional cash transfer (CCT) programs during the last 2 decades. As a consequence of the COVID-19 pandemic, poverty rates have markedly increased, and a large number of newly low-income individuals, especially children, have been left unprotected. Objective: To evaluate the association of CCT programs with child health in Latin American countries during the last 2 decades and forecast child mortality trends up to 2030 according to CCT alternative implementation options. Design, Setting, and Participants: This cohort study used a multicountry, longitudinal, ecological design with multivariable negative binomial regression models, which were adjusted for all relevant demographic, socioeconomic, and health care variables, integrating the retrospective impact evaluations from January 1, 2000, to December 31, 2019, with dynamic microsimulation models to forecast potential child mortality scenarios up to 2030. The study cohort included 4882 municipalities from Brazil, Ecuador, and Mexico with adequate quality of civil registration and vital statistics according to a validated multidimensional criterion. Data analysis was performed from September 2022 to February 2023. Exposure: Conditional cash transfer coverage of the target (lowest-income) population categorized into 4 levels: low (0%-29.9%), intermediate (30.0%-69.9%), high (70.0%-99.9%), and consolidated (≥100%). Main Outcomes and Measures: The main outcomes were mortality rates for those younger than 5 years and hospitalization rates (per 1000 live births), overall and by poverty-related causes (diarrheal, malnutrition, tuberculosis, malaria, lower respiratory tract infections, and HIV/AIDS), and the mortality rates for those younger than 5 years by age groups, namely, neonatal (0-28 days), postneonatal (28 days to 1 year), infant (<1 year), and toddler (1-4 years). Results: The retrospective analysis included 4882 municipalities. During the study period of January 1, 2000, to December 31, 2019, mortality in Brazil, Ecuador, and Mexico decreased by 7.8% in children and 6.5% in infants, and an increase in coverage of CCT programs of 76.8% was observed in these Latin American countries. Conditional cash transfer programs were associated with significant reductions of mortality rates in those younger than 5 years (rate ratio [RR], 0.76; 95% CI, 0.75-0.76), having prevented 738 919 (95% CI, 695 641-782 104) child deaths during this period. The association of highest coverage of CCT programs was stronger with poverty-related diseases, such as malnutrition (RR, 0.33; 95% CI, 0.31-0.35), diarrhea (RR, 0.41; 95% CI, 0.40-0.43), lower respiratory tract infections (RR, 0.66, 95% CI, 0.65-0.68), malaria (RR, 0.76; 95% CI, 0.63-0.93), tuberculosis (RR, 0.62; 95% CI, 0.48-0.79), and HIV/AIDS (RR, 0.32; 95% CI, 0.28-0.37). Several sensitivity and triangulation analyses confirmed the robustness of the results. Considering a scenario of moderate economic crisis, a mitigation strategy that will increase the coverage of CCTs to protect those newly in poverty could reduce the mortality rate for those younger than 5 years by up to 17% (RR, 0.83; 95% CI, 0.80-0.85) and prevent 153 601 (95% CI, 127 441-180 600) child deaths by 2030 in Brazil, Ecuador, and Mexico. Conclusions and Relevance: The results of this cohort study suggest that the expansion of CCT programs could strongly reduce childhood hospitalization and mortality in Latin America and should be considered an effective strategy to mitigate the health impact of the current global economic crisis in low- and middle-income countries.

Curso de atualização em emergências médicas: aula 20: colangite aguda: diagnóstico e terapêutica / Updating medical emergencies course: class 20: acute cholangitis: diagnostic and therapeutic

A colangite aguda corresponde à infecção ascendente das vias biliares e geralmente está relacionada com as bactérias entéricas - gram-negativas, anaeróbios e enterococos. O fator patogênico mais importante é o obstrutivo, pois a presença de bactérias na bile não é suficiente para causar infecção das vias biliares se não estiver presente o componente obstrutivo. Dentre eles, a coledocolitíase é o principal elemento em cerca de 70% a 80% dos casos. Clinicamente, a tríade clássica - febre com calafrios, dor do hipocêndrio direito e icterícia - descrita por Charcot em 1877 manifesta-se em cerca de 70% a 80% dos pacientes. A ultrassonografia abdominal (e mais raramente a colangiopancreatografia por ressonância magnética) deve ser o método de escolha, por ser hábil em detectar dilatação da via biliar acima do local da obstrução e também por poder revelar sua causa. A terapêutica da colangite bacteriana aguda deve alicerçar-se na ressuscitação volêmica, antibioticoterapia e desobstrução da via biliar com consequente drenagem, sendo esta última a pedra angular da terapia emergencial da colangite aguda, que pode ser feita por via endoscópica (CPRE) ou transparietal (PTC).

Acute cholangitis corresponds to the ascending infection of the biliary tract and is usually associated with enteric bacteria - gram-negative, anaerobes and enterococci. The most important pathogenic factor is the obstruction because the presence of bacteria in bile is not sufficient to cause infection of the biliary tract in the absence of one obstructive component. Among these, choledocholithiasis is the main element in about 70% to 80% of cases. Clinically, the classic triad - fever with chills, pain in the right hypochondrium and jaundice - described by Charcot in 1877, manifests itself in about 70% to 80% of patients. The abdominal ultrasound (and, less frequently, magnetic resonance cholangiopancreatography) should be the method of choice because it is able to detect bile duct dilation above the site of the obstruction and also to reveal its cause. The treatment of acute bacterial cholangitis must be based on fluid resuscitation, antibiotics and clearing of the bile duct with subsequent drainage, the latter being the cornerstone of emergency therapy of acute cholangitis, which can be performed endoscopically (ERCP) or transparietal (PTC).
