The Systemic Immune-Inflammation Index Predicts In-Hospital Mortality in Patients Who Underwent On-Pump Cardiac Surgery. / O Índice de Imuno Inflamação Sistêmica Prevê Mortalidade Hospitalar em Pacientes Submetidos à Cirurgia Cardíaca com Circulação Extracorpórea.

BACKGROUND: Systemic immune-inflammation index (SII), a new inflammatory index calculated using platelet, neutrophil, and lymphocyte counts, has been demonstrated to be an independent risk factor for the identification of high-risk coronary artery disease in patients undergoing percutaneous coronary intervention and cardiovascular surgery with cardiopulmonary bypass (CPB). The relationship between SII and CPB-related mortality rates remains unclear. OBJECTIVE: This research was designed to investigate the use of SII to predict in-hospital mortality in patients undergoing cardiac surgery with CPB. METHODS: Four hundred eighty patients who underwent a cardiac procedure involving CPB over 3 years, were obtained from the hospital's database. The demographic data, comorbidities, hematological and biochemical profiles, and operative data of the groups were compared. Multiple logistic regression analyses were done to determine independent predictors of mortality. Prognostic factors were assessed by multivariate analysis, and the predictive values of SII, neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR) for mortality were compared. A p-value <0.05 was considered significant. RESULTS: Of 480 patients, 78 developed in-hospital mortality after cardiac surgery. SII was an independent predictor of in-hospital mortality (Odds ratio: 1.003, 95% confidence interval: 1.001-1.005, p<0.001). The cut-off value of the SII was >811.93 with 65% sensitivity and 65% specificity (area under the curve: 0.690). The predictive values of SII, PLR, and NLR were close to each other. CONCLUSION: High preoperative SII scores can be used for early determination of appropriate treatments, which may improve surgical outcomes of cardiac surgery in the future.

FUNDAMENTO: O índice de imuno-inflamação sistêmica (SII), um novo índice inflamatório calculado usando contagens de plaquetas, neutrófilos e linfócitos, demonstrou ser um fator de risco independente para a identificação de doença arterial coronariana de alto risco em pacientes submetidos a intervenção coronária percutânea e cardiovascular e cirurgia com circulação extracorpórea (CEC). A relação entre as taxas de mortalidade relacionadas ao SII e à CEC permanece obscura. OBJETIVO: Esta pesquisa foi desenhada para investigar o uso do SII para prever mortalidade hospitalar em pacientes submetidos à cirurgia cardíaca com CEC. MÉTODOS: Quatrocentos e oitenta pacientes submetidos a procedimento cardíaco envolvendo CEC durante 3 anos foram coletados do banco de dados do hospital. Foram comparados os dados demográficos, comorbidades, perfis hematológicos e bioquímico e dados operatórios dos grupos. Análises múltiplas de regressão logística foram feitas para determinar preditores independentes de mortalidade. Os fatores prognósticos foram avaliados por análise multivariada e os valores preditivos de SII, relação neutrófilo-linfócito (NLR) e razão plaqueta-linfócito (PLR) para mortalidade foram comparados. Um valor de p <0,05 foi considerado significativo. RESULTADOS: Dos 480 pacientes, 78 desenvolveram mortalidade hospitalar após cirurgia cardíaca. O SII foi um preditor independente de mortalidade hospitalar (odds ratio: 1,003, intervalo de confiança de 95%: 1,001-1,005, p<0,001). O valor de corte do SII foi >811,93 com sensibilidade de 65% e especificidade de 65% (área sob a curva: 0,690). Os valores preditivos de SII, PLR e NLR foram próximos entre si. CONCLUSÃO: Altos escores pré-operatórios do SII podem ser usados para determinação precoce de tratamentos apropriados, o que pode melhorar os resultados cirúrgicos de cirurgia cardíaca no futuro.

Text mining analysis to understand the impact of online news on public health response: case of syphilis epidemic in Brazil.

Background: To effectively combat the rising incidence of syphilis, the Brazilian Ministry of Health (MoH) created a National Rapid Response to Syphilis with actions aimed at bolstering epidemiological surveillance of acquired, congenital syphilis, and syphilis during pregnancy complemented with communication activities to raise population awareness and to increase uptake of testing that targeted mass media outlets from November 2018 to March 2019 throughout Brazil, and mainly areas with high rates of syphilis. This study analyzes the volume and quality of online news content on syphilis in Brazil between 2015 and 2019 and examines its effect on testing. Methods: The collection and processing of online news were automated by means of a proprietary digital health ecosystem established for the study. We applied text data mining techniques to online news to extract patterns from categories of text. The presence and combination of such categories in collected texts determined the quality of news that were analyzed to classify them as high-, medium-and low-quality news. We examined the correlation between the quality of news and the volume of syphilis testing using Spearman's Rank Correlation Coefficient. Results: 1,049 web pages were collected using a Google Search API, of which 630 were categorized as earned media. We observed a steady increase in the number of news on syphilis in 2015 (n = 18), 2016 (n = 26), and 2017 (n = 42), with a substantial rise in the number of news in 2018 (n = 107) and 2019 (n = 437), although the relative proportion of high-quality news remained consistently high (77.6 and 70.5% respectively) and in line with similar years. We found a correlation between news quality and syphilis testing performed in primary health care with an increase of 82.32, 78.13, and 73.20%, respectively, in the three types of treponemal tests used to confirm an infection. Conclusion: Effective communication strategies that lead to dissemination of high quality of information are important to increase uptake of public health policy actions.

Respiratory, Cardiac, and Neuropsychiatric Manifestations of Postacute Sequelae of Coronavirus Disease 2019 in Lima, Peru.

Background: Few studies have examined the burden of postacute sequelae of coronavirus disease 2019 (COVID-19) (PASC) in low- and middle-income countries. We sought to characterize PASC with self-reported questionnaires and clinical examinations of end-organ function in Lima, Peru. Methods: From January to July 2021, we recruited participants at least 8 weeks after COVID-19 diagnosis from a case registry in Lima, Peru. We evaluated participants for PASC with questionnaires, neuropsychiatric evaluations, chest X-ray, spirometry, electrocardiogram, and echocardiogram. We used multivariable models to identify risk factors for PASC. Results: We assessed 989 participants for PASC at a median 4.7 months after diagnosis. Clinically significant respiratory symptoms were reported by 68.3% of participants, particularly those who had been severely ill during acute COVID-19, and were associated with cardiac findings of ventricular hypertrophy or dilation on echocardiogram. Neuropsychiatric questionnaires were consistent with depression in 20.7% and cognitive impairment in 8.0%. Female sex and older age were associated with increased risk of respiratory (adjusted odds ratio [aOR], 2.36 [95% confidence interval {CI}, 1.69-3.31] and aOR, 1.01 [95% CI, 1.00-1.03], respectively) and neuropsychiatric sequelae (aOR, 2.99 [95% CI, 2.16-4.18] and aOR, 1.02 [95% CI, 1.01-1.03], respectively). Conclusions: COVID-19 survivors in Lima, Peru, experienced frequent postacute respiratory symptoms and depression, particularly among older and female participants. Clinical examinations highlighted the need for cardiopulmonary rehabilitation among persons with severe COVID-19; psychosocial support may be required among all COVID-19 survivors.

Identifying the risk factors for intracranial herniation in patients with cerebral venous thrombosis.

BACKGROUND: Cerebral venous sinus thrombosis (CVST) is not as well understood as an ischemic stroke of arterial origin. Although the prognosis of CVST is usually good, parenchymal lesions may occur in some patients, and the development of intracranial herniation may result in death. For this reason, recognizing the risk factors for intracranial herniation and accurately determining those patients who should undergo decompressive craniectomy is important. OBJECTIVE: This study aims to determine the risk factors for intracranial herniation in patients with CVST. METHODS: A total of 177 patients diagnosed with CVST between 2015 and 2021 in our tertiary center were retrospectively included in this study. RESULTS: Of the 177 patients, 124 were female and 53 were male with mean ages of 40.65 ± 13.23 and 44.13 ± 17.09, respectively. Among those, 18 patients had developed intracranial herniation. A significant statistical relationship was observed between superior sagittal sinus thrombosis, sinus rectus thrombosis, venous collateral score, nonhemorrhagic venous infarct, presence of malignancy, small juxtacortical hemorrhage, and cortical vein thrombosis. The binary logistic regression analysis results showed that the most significant variables were the venous collateral score of 0, malignancy, and small juxtacortical hemorrhages. CONCLUSION: This study identified small juxtacortical hemorrhages, the presence of malignancy, and a venous collateral score of 0 to be independent risk factors for intracranial herniation in CVST patients. Drawing on these results, we recommend close clinical observation of CVST patients, as they may be candidates for decompressive craniectomy.

ANTECEDENTES: A trombose do seio venoso cerebral (CVST) não é tão bem compreendida como um acidente vascular cerebral isquémico de origem arterial. Embora o prognóstico de CVST seja geralmente bom lesões parenquimatosas podem ocorrer em alguns pacientes e o desenvolvimento de herniação intracraniana pode resultar em morte. Por esse motivo é importante reconhecer os fatores de risco para hérnia intracraniana e determinar com precisão os pacientes que devem ser submetidos à craniectomia descompressiva. OBJETIVO: Este estudo tem como objetivo determinar os fatores de risco para herniação intracraniana em pacientes com CVST. MéTODOS: Um total de 177 pacientes diagnosticados com CVST entre 2015 e 2021 em nosso centro terciário foram retrospectivamente incluídos neste estudo. RESULTADOS: Dos 177 pacientes 124 eram do sexo feminino e 53 do masculino com média de idade de 40 65 ± 13 23 e 44 13 ± 17 09 respectivamente. Destes 18 pacientes desenvolveram hérnia intracraniana. Uma relação estatística significativa foi observada entre trombose do seio sagital superior trombose do seio reto escore de colateral venosa infarto venoso não hemorrágico presença de malignidade pequena hemorragia justacortical e trombose da veia cortical. Os resultados da análise de regressão logística binária mostraram que as variáveis mais significativas foram o escore colateral venoso de 0 malignidade e pequenas hemorragias justacorticais. CONCLUSãO: Este estudo identificou pequenas hemorragias justacorticais a presença de malignidade e um escore colateral venoso de 0 como fatores de risco independentes para herniação intracraniana em pacientes CVST. Com base nesses resultados recomendamos uma observação clínica rigorosa dos pacientes CVST pois eles podem ser candidatos à craniectomia descompressiva.

Predictive Values of Systemic Immune-Inflammation Index in New-Onset Atrial Fibrillation Following Coronary Artery Bypass Grafting

ABSTRACT Introduction: We investigated the relationship between the newly-defined systemic immune-inflammation index and the new-onset atrial fibrillation in patients undergoing coronary artery bypass grafting. Method: This study included 392 patients who underwent coronary artery bypass grafting. We divided the participants into two groups as those with and without new-onset atrial fibrillation. Prior to coronary artery bypass grafting, we evaluated blood samples, including systemic immune-inflammation index, and other laboratory parameters of the patients. We formulized the systemic immune-inflammation index score as platelet × neutrophil/lymphocyte counts. Results: The findings revealed that new-onset atrial fibrillation occurred in 80 (20.4%) of 392 patients during follow-ups. Such patients had higher systemic immune-inflammation index, neutrophil/lymphocyte ratio, and C-reactive protein levels than those who did not develop new-onset atrial fibrillation (P<0.001, P<0.001, P=0.010, respectively). In receiver operating characteristic curve analysis, systemic immune-inflammation index levels > 712.8 predicted new-onset atrial fibrillation with a sensitivity of 85% and a specificity of 61.2% (area under the curve: 0.781, 95% confidence interval: 0.727-0.835; P<0.001). Conclusion: Overall, systemic immune-inflammation index, a novel inflammatory marker, may be used as a decisive marker to predict the development of atrial fibrillation following coronary artery bypass grafting.

Impact of morphological characteristics and motor skills when performing gyaku tsuki / Impacto de las características morfológicas y de las destrezas motoras al realizar gyaku tsuki / Impacto das características morfológicas e das habilidades motoras ao realizar gyaku tsuki

ABSTRACT Objective The aim of this study was to determine the influence of morphology on karate characteristics and basic motor skills for the criterion variable counter-punch (gyako zuki) in boys, after a two-year training program. Methods A system of 25 variables (12 morphological, 12 motor, and one situational (gyako zuki)) was applied in a sample of 82 karatists, aged 10 to 14 years. Data were processed using regression analysis. Results Body weight had a statistically significant influence on the criterion variable in the initial measurement, as well as on the triceps and back skinfolds in the final measurement. In the motor space, semi-squat endurance had a significant impact on both initial and final measurements. In the reduced system, triple jump, half-squat endurance, and long jump impacted the initial measurement, while the 30-second torso lift, hyperextension on the bench, and semi-squat endurance impacted the final measurement. Conclusion From the data obtained, it can be concluded that the counter-punch (gyako zuki) performance results were better in participants with higher body weight, longer arms, less subcutaneous upper arm and back fat, greater static and explosive power in the lower limbs, and greater hamstring and spine flexibility.

Framing of COVID-19 in Newspapers: A Perspective from the US-Mexico Border.

The degree to which the media report a health emergency affects the seriousness with which the people respond to combat the health crisis. Engagement from local newspapers in the US has received scant scrutiny, even though there is a sizable body of scholarship on the analysis of COVID-19 news. We fill this void by focusing on the Rio Grande Valley area of the US-Mexico border. To understand the differences, we compared such local news coverage with the coverage of a national news outlet. After collecting the relevant news articles, we used sentiment analysis, rapid automatic keyword extraction (RAKE), and co-occurrence network analysis to examine the main themes and sentiments of COVID-19 news articles. The RAKE identified that county-specific news or local regulations are more prevalent among the key terms in The Monitor which are absent in USA Today. The co-occurrence network shows the coverage of the disruption of sports season in USA Today which is not present in The Monitor. The sentiment analysis presents fear emotion is more dominant in USA Today, but trust emotion becomes more prevalent in The Monitor news coverage. These findings show us that, although the subject of the health emergency is the same, local and national newspapers describe it in different ways, and the sentiments they convey are also not the same.

Sentiment Analysis in Understanding the Potential of Online News in the Public Health Crisis Response.

This study analyzes online news disseminated throughout the pre-, during-, and post-intervention periods of the "Syphilis No!" Project, which was developed in Brazil between November 2018 and March 2019. We investigated the influence of sentiment aspects of news to explore their possible relationships with syphilis testing data in response to the syphilis epidemic in Brazil. A dictionary-based technique (VADER) was chosen to perform sentiment analysis considering the Brazilian Portuguese language. Finally, the data collected were used in statistical tests to obtain other indicators, such as correlation and distribution analysis. Of the 627 news items, 198 (31.58%) were classified as a sentiment of security (TP2; stands for the news type 2), whereas 429 (68.42%) were classified as sentiments that instilled vulnerability (TP3; stands for the news type 3). The correlation between the number of syphilis tests and the number of news types TP2 and TP3 was verified from (i) 2015 to 2017 and (ii) 2018 to 2019. For the TP2 type news, in all periods, the p-values were greater than 0.05, thus generating inconclusive results. From 2015 to 2017, there was an ρ = 0.33 correlation between TP3 news and testing data (p-value = 0.04); the years 2018 and 2019 presented a ρ = 0.67 correlation between TP3 news and the number of syphilis tests performed per month, with p-value = 0.0003. In addition, Granger's test was performed between TP3 news and syphilis testing, which resulted in a p-value = 0.002, thus indicating the existence of Granger causality between these time series. By applying natural language processing to sentiment and informational content analysis of public health campaigns, it was found that the most substantial increase in testing was strongly related to attitude-inducing content (TP3).

Diagnostic value of serum levels of galanin and obestatin in patients with gastric cancer.

OBJECTIVE: Gastric cancer ranks the third among the cancer-related deaths. It is diagnosed at advanced stage in many patients due to malignant proliferation and has a poor prognosis. Currently, no instrument or biomarker has been proven to diagnose the disease before the advanced stages. This study aimed to measure the serum levels of galanin and obestatin, which were examined in various studies including cancer studies, and to discuss their diagnostic value in gastric cancers. METHODS: In this study, 30 adult patients with gastric cancer and 30 healthy adults in the control group were examined prospectively. The demographic characteristics and serum levels of galanin and obestatin in the patient and control groups were recorded. RESULTS: The mean serum level of galanin in the patient and control groups was 19.73±5.04 and 35.59±10.94 pg/mL, respectively. The mean serum level of obestatin in the patient and control groups was 40.21±5.82 and 15.15±3.32 ng/mL, respectively. A significant difference was found between the groups (p<0.001). CONCLUSION: Serum levels of galanin were lower and serum levels of obestatin were higher in patients with gastric cancer compared to the healthy individuals. Serum levels of obestatin and galanin can be used as potential biomarkers in the diagnosis of gastric cancer.

The Importance of HbA1c and Left Ventricular Ejection Fraction in Predicting the Development of Postoperative Mortality and Complications in Coronary Artery Bypass Graft Surgery

Abstract Introduction: In this study, we aimed to investigate the relationship between postoperative mortality, morbidity, hospital stay and development of postoperative complications with the glycosylated hemoglobin (HbA1c) level and low left ventricular ejection fraction (LVEF) in diabetic and non-diabetic patients who underwent elective coronary artery bypass (CABG) surgery. Methods: The medical records of patients who underwent CABG at our clinic between January 2015 and December 2019 were retrospectively analyzed. All patients were divided into two groups according to their diabetes mellitus (DM) diagnosis. Diabetic patients were also divided into two groups according to their HbA1c levels. The HbA1c threshold value was 7%. All patients were divided into two groups in terms of LVEF. The LVEF threshold value was 40%. Results: We analyzed 393 patients, of which 304 (77.4%) were male and 177 (45.04%) patients were diabetic. For lower LVEF and HbA1c values, we found no relationship between postoperative mortality, prolonged intensive care unit (ICU) stay and development of postoperative complications. Deep surgical site infection (DSSI) was found to be more common in diabetic patients who had a higher HbA1c value. Length of hospital stay was longer in diabetic patients with HbA1c levels <7%. Conclusion: No statistically significant relationship was found between LVEF and HbA1c levels and postoperative mortality, prolonged ICU stay and postoperative complications.

Impact of Single versus Double Clamp Technique on Blood Lactate Levels and Postoperative Complications in Coronary Artery Bypass Surgery

Abstract Introduction: Cardiopulmonary bypass (CPB) is associated with hyperlactatemia, which leads to adverse clinical outcomes. No study has examined the effect of different clamping techniques on postoperative hyperlactatemia (PHL). Thus, we aimed to evaluate the impact of two different techniques on PHL and the clinical outcomes in patients undergoing isolated coronary artery bypass surgery. Methods: This retrospective study included 100 patients who underwent isolated CPB either with single clamp technique (SCT, n=47) or double clamp technique (DCT, n=53). Demographic and preoperative laboratory data, as well as operative features and arterial blood lactate levels at the onset and at the end of CPB, were collected from patient charts. Results: Blood lactate levels collected at the end of CPB did not differ significantly between groups whereas intraoperative lactate increased significantly in both groups (P<0.005). PHL developed in 16 patients (32%). There was no meaningful difference in SCT and DCT in this regard. Left internal mammary artery was used more frequently in the DCT group than in the SCT group. While the cross-clamp time was significantly longer in the SCT group, there was no difference regarding CPB time. Among postoperative complications, only the incidence of stroke was significantly higher in the DCT group than in the SCT group (10.6% vs. 0%, P=0.020). CPB time, cross-clamp time and numbers of proximal saphenous graft and distal anastomosis showed a significant positive correlation with the postoperative lactate level. In the regression analysis, CPB time emerged as the only independent predictor of PHL (OR 1.04, CI 95% 1.01-1.07, P=0.011). Conclusion: There was no difference in postoperative blood lactate levels between SCT and DCT groups.

Use of Interrupted Time Series Analysis in Understanding the Course of the Congenital Syphilis Epidemic in Brazil.

Background: To fight against the rising incidence of syphilis, the Brazilian Ministry of Health (MoH) launched the "Syphilis No!" Project (SNP), with specific resources funded by a parliamentary amendment. Then, in 2018, a national rapid response started to be implemented on the Brazilian Unified Health System (SUS, Sistema Único de Saúde) in two strategic lines (1) to reinforce SUS's universal actions and (2) to implement specific ones to 100 municipalities chosen by the MoH as priorities for syphilis congenital response. In 2015, such localities represented 6895% of congenital syphilis cases in Brazil. In this context, SNP has implemented actions to strengthen epidemiological surveillance of acquired syphilis and congenital syphilis by instituting an integrated and collaborative response through health services networks and reinforcing interstate relations. Methods: A quasi-experimental study using time series analysis was conducted to assess immediate impacts and changes to the trend in national congenital syphilis before and after the project, from September 2016 to December 2019. Data were assessed considering rates of congenital syphilis per 1,000 live births in all priority municipalities (n=100) covered by the project and in non-priority municipalities (n=5,470) from all five macro-regions of Brazil. Findings: Priority municipalities showed a greater reduction (change in trend) in comparison to non-priority. The linear regression model revealed trend changes after the intervention, with both groups of municipalities showing a drop in the average monthly number of cases per 1,000 live births, with a reduction of -0·21 (CI 95% -0·33 to -0·09; p=0·0011) in priority municipalities and of -0·10 (CI 95% -0.19 to -0.02; p=0·0216) in non-priority municipalities. Interpretation: The study using ITS provides important evidence on the direction, timing, and magnitude of the effects of interventions introduced as part of the SNP on congenital syphilis in Brazil. Our results suggest that the Syphilis No! Project influenced the trends of congenital syphilis in Brazil from 2018, with higher reductions achieved in the priority municipalities. Funding: The research is funded by a grant to the Syphilis No! Project from Brazilian Ministry of Health (Project Number: 54/2017). The funders had no role in study design, analysis, decision to publish, or preparation of the manuscript.

METHODS: This retrospective study included 100 patients who underwent isolated CPB either with single clamp technique (SCT, n=47) or double clamp technique (DCT, n=53). Demographic and preoperative laboratory data, as well as operative features and arterial blood lactate levels at the onset and at the end of CPB, were collected from patient charts. RESULTS: Blood lactate levels collected at the end of CPB did not differ significantly between groups whereas intraoperative lactate increased significantly in both groups (P<0.005). PHL developed in 16 patients (32%). There was no meaningful difference in SCT and DCT in this regard. Left internal mammary artery was used more frequently in the DCT group than in the SCT group. While the cross-clamp time was significantly longer in the SCT group, there was no difference regarding CPB time. Among postoperative complications, only the incidence of stroke was significantly higher in the DCT group than in the SCT group (10.6% vs. 0%, P=0.020). CPB time, cross-clamp time and numbers of proximal saphenous graft and distal anastomosis showed a significant positive correlation with the postoperative lactate level. In the regression analysis, CPB time emerged as the only independent predictor of PHL (OR 1.04, CI 95% 1.01-1.07, P=0.011). CONCLUSION: There was no difference in postoperative blood lactate levels between SCT and DCT groups.

The Importance of HbA1c and Left Ventricular Ejection Fraction in Predicting the Development of Postoperative Mortality and Complications in Coronary Artery Bypass Graft Surgery.

INTRODUCTION: In this study, we aimed to investigate the relationship between postoperative mortality, morbidity, hospital stay and development of postoperative complications with the glycosylated hemoglobin (HbA1c) level and low left ventricular ejection fraction (LVEF) in diabetic and non-diabetic patients who underwent elective coronary artery bypass (CABG) surgery. METHODS: The medical records of patients who underwent CABG at our clinic between January 2015 and December 2019 were retrospectively analyzed. All patients were divided into two groups according to their diabetes mellitus (DM) diagnosis. Diabetic patients were also divided into two groups according to their HbA1c levels. The HbA1c threshold value was 7%. All patients were divided into two groups in terms of LVEF. The LVEF threshold value was 40%. RESULTS: We analyzed 393 patients, of which 304 (77.4%) were male and 177 (45.04%) patients were diabetic. For lower LVEF and HbA1c values, we found no relationship between postoperative mortality, prolonged intensive care unit (ICU) stay and development of postoperative complications. Deep surgical site infection (DSSI) was found to be more common in diabetic patients who had a higher HbA1c value. Length of hospital stay was longer in diabetic patients with HbA1c levels <7%. CONCLUSION: No statistically significant relationship was found between LVEF and HbA1c levels and postoperative mortality, prolonged ICU stay and postoperative complications.

Transition to universal primary health care coverage in Brazil: analysis of uptake and expansion patterns of Brazil’s Family Health Strategy (1998-2012)

Family Health Strategy, the primary health care program in Brazil, has been scaled up throughout the country, but its expansion has been heterogeneous across municipalities. We investigate if there are unique municipal characteristics that can explain the timing of uptake and the pattern of expansion of the Family Health Strategy from years 1998 to 2012. We categorized municipalities in six groups based on the relative speed of the Family Health Strategy uptake and the pattern of Family Health Strategy coverage expansion. We assembled data for 11 indicators for years 2000 and 2010, for 5,507 municipalities, and assessed differences in indicators across the six groups, which we mapped to examine spatial heterogeneities. Important factors differentiating early and late adopters of the Family Health Strategy were supply of doctors and population density. Sustained coverage expansion was related mainly to population size, marginal benefits of the program and doctors’ supply. The uptake was widespread nationwide with no distinct patterns among regions, but highly heterogeneous at the state and municipal level. The Brazilian experience of expanding primary health care offers three lessons in relation to factors influencing diffusion of primary health care. First, the funding mechanism is critical for program implementation, and must be accompanied by ways to support the supply of primary care physicians in low density areas. Second, in more developed and bigger areas the main challenge is lack of incentives to pursue universal coverage, especially due to the availability of private insurance. Third, population size is a crucial element to guarantee coverage sustainability over time.

Determinants of the Early Childhood Development Index among children aged < 5 years in Bangladesh, Costa Rica and Ghana: a comparative study.

BACKGROUND: Early child development is a crucial factor for children that controls health and well-being in later life. AIMS: To determine the influence of sociodemographic factors on the Early Child Development Index (ECDI) among children aged < 5 years. METHODS: The analysis was performed using cross-sectional survey data from 2019, 2017-2018 and 2018 Multiple Indicator Cluster Surveys from Bangladesh, Ghana and Costa Rica, respectively. We used the χ2 test for bivariate analysis and binary logistic regression model for multivariate analysis for all 3 countries. All the statistical analyses were performed with IBM SPSS version 25 and R version 4.0.0. RESULTS: Child age and sex, followed by maternal education level, economic status, child nutritional status, reading children's books, and maternal functional difficulties had the greatest effect on ECDI. Children aged 36-47 months had lower odds of development than those aged 48-59 months, and boys had lower odds of development than girls in Bangladesh, Costa Rica and Ghana. Urban children had lower odds of development than rural children in Costa Rica but higher odds in Ghana. CONCLUSION: We recommend that governments should take the necessary steps to enhance children's early development and well-being in all 3 countries by raising education, improving economic conditions and providing balanced nutrition.
