BACKGROUND: Tracheal, bronchus, and lung cancer (TBL) is a major cause of mortality and top contributor to productivity loss in large emerging economies such as the BRICS (Brazil, Russia, India, China, and South Africa). We examined the time trends of TBL mortality across the BRICS to better understand the disease burden in these countries and inform public health and healthcare resource allocation. METHODS: TBL mortality-related data between 1990 and 2019 were obtained from the Global Burden of Disease Study 2019 and analyzed using age-period-cohort models. Net drift (local drift) was used to describe the expected age-adjusted TBL mortality rate over time overall (each age group); the longitudinal age curve was used to reflect the age effect; the period rate ratios (RRs) were used to reflect the period effect; and the cohort RR was used to reflect the cohort effect. RESULTS: In 2019, there were 958.3 thousand TBL deaths across the BRICS, representing 46.9% of the global TBL deaths. From 1990 to 2019, the age-standardized mortality rate (ASMR) of TBL decreased in Russia, Brazil, and South Africa while increased in China and India, with the largest reduction reported in Russia (-29.6%) and the largest increase in China (+22.4%). India showed an overall increase (+15.7%) in TBL mortality but the mortality risk decreased among individuals born after 1990 (men) and 1995 (women). Although South Africa and Brazil experienced an overall decline in TBL mortality, their recent birth cohorts, such as Brazilian individuals born after 1985 (men) and 1980 (women), and South African men born after 1995, had an increasing TBL mortality risk. China has experienced an overall increase in TBL mortality, with the mortality risk rising among individuals born after 1995 for both men and women. Russia, which had the highest TBL mortality among the BRICS countries in 1990, has demonstrated significant improvement over the past three decades. CONCLUSIONS Over the past 30 years, the BRICS accounted for an increasing proportion of global TBL mortality. TBL mortality increased in older women in all the BRICS countries except Russia. Among the recent birth cohort, the risk of TBL mortality increased in Brazil, China, and South Africa. More effective efforts are needed in the BRICS to reduce the burden of TBL and help achieve the United Nation's Sustainable Development Goals.

OBJECTIVE: To analyze the recent severity of COVID-19 in various countries. METHODS: Data were ollected on the epidemic situation of COVID-19 in various countries as of January 16, 2021, and the scale and overall trend of the epidemic were retrospectively described; combined with the recent trend of newly confirmed cases, from January 10 to 16 (the 54th week) and the newly confirmed cases indexes, such as the number and incidence density the severity of the epidemic was classified. Feasible suggestions were put forward based on the variation of the virus, actual data of vaccine research and development and possible existence in many countries. RESULTS: Up to January 16, 2021, there were 92 510 419 confirmed cases worldwide; 4 849 301 new confirmed cases were confirmed in the 54th week, and they were still growing. Among all the continents, the cumulative number of confirmed cases in Europe, North America, and Asia has exceeded 21 million, and the number of new confirmed cases in a single week in North America, South America and Asia were all increasing. Among the countries, the cumulative number of confirmed cases in 18 countries including the United States, India, and Brazil was more than 1 million, accounting for 77.04% of the total number of cumulative confirmed cases in the world. Eleven countries including the United States, Brazil, France, Spain, Colombia, The United Kingdom, Russia, Germany, South Africa, Italy, and India are at higher risk of the epidemic; The United States, Brazil, France, Spain, and Colombia were still experiencing new confirmed cases and increasing status, the risk of the epidemic was greater. Novel coronavirus mutates frequently, up to February 2021, there had been 3 931 mutant genotypes in the world. At the same time, a total of 11 vaccines were successfully launched, however we were still facing some troubles, such as the global shortage of vaccines, the public's willingness to vaccinate needed to be improved, and equity in the distribution of vaccines. CONCLUSION The global epidemic situation is still getting worse, with repeated epidemics in all the continents and countries, and has not been fundamentally controlled. At the continent level, North America, South America, and Europe have the most severe epidemics; at the national level, The United States, Brazil, France, Spain, Colombia and other countries have higher epidemic risks. Focusing on the severely affected countries will help bring the global epidemic under control as soon as possible. Under the premise of ensuring the safety and effectiveness of the vaccines, it is a key and feasible direction to improve the yield and vaccination rate of the vaccines, shorten the onset time of the vaccines and prolong the immune persistence.

BACKGROUND: Given the important repercussions that sociodemographic factors can have on physical activity, especially in the field of leisure, and cardiometabolic risk, it seems relevant to analyze the implications of these variables on the relationship between physical activity in leisure time (LTPA) and cardiometabolic risk. In this sense, the present study aims to verify the moderating role of biologic and socioeconomic factors in the relationship between LTPA and cardiometabolic risk in adolescents in southern Brazil. METHODS: Cross-sectional study that included 1596 adolescents selected at random (58.2% girls), aged between 10 and 17 years. LTPA, biological and socioeconomic factors were assessed using a self-reported questionnaire and the cardiometabolic risk score (total cholesterol/HDL-c ratio, triglycerides, fasting glucose, systolic blood pressure, and waist circumference, considering the participant's age and sex) was included as an outcome. Associations and moderations were tested by multiple linear regression models. RESULTS: It was observed a positive interaction of LTPA and sex (p = 0.048) and LTPA and school system (p = 0.037), and negative interaction of LTPA and skin color (p = 0.040), indicating that these factors were moderators in the relationship between LTPA and clustered cardiometabolic risk score (cMetS) in adolescents. A reduction in cardiometabolic risk was observed according to the increase in weekly minutes of LTPA among boys, non-white adolescents, and students from municipal schools. CONCLUSIONS The association between LTPA and cardiometabolic risk was moderated by sex, skin color, and school system in adolescents from southern Brazil.

Pulmonary paragonimiasis and tuberculosis are endemic in Asia, South America, and Africa. However, differential diagnosis among the diseases is difficult because they present with similar clinical symptoms and diagnostic features. Here, we report a case of pulmonary paragonimiasis that was identified using Ziehl-Neelsen stain after initially being assessed for pulmonary tuberculosis. Following anti-Paragonimus chemotherapy, the patient's symptoms, laboratory test results, and lung lesions improved. Thus, the identification of Paragonimus westermani using Ziehl-Neelsen stain can be considered in the diagnosis.

OBJECTIVE: To verify the association between sleep duration and television time with cardiometabolic risk and the moderating role of age, gender, and skin color/ethnicity in this relationship among adolescents. METHODS: Cross-sectional study with 1411 adolescents (800 girls) aged 10 to 17 years. Television time, sleep duration, age, gender, and skin color/ethnicity were obtained by self-reported questionnaire. Cardiometabolic risk was evaluated using the continuous metabolic risk score, by the sum of the standard z-score values for each risk factor: high-density lipoprotein cholesterol, triglycerides, glycemia, cardiorespiratory fitness, systolic blood pressure, and waist circumference. Generalized linear regression models were used. RESULTS: There was an association between television time and cardiometabolic risk (β, 0.002; 95% CI, 0.001; 0.003). Short sleep duration (β, 0.422; 95% CI, 0.012; 0.833) was positively associated with cardiometabolic risk. Additionally, age moderated the relationship between television time and cardiometabolic risk (β, - 0.009; 95% CI, - 0.002; - 0.001), suggesting that this relationship was stronger at ages 11 and 13 years (β, 0.004; 95% CI, 0.001; 0.006) compared to 13 to 15 years (β, 0.002; 95% CI, 0.001; 0.004). No association was found in older adolescents (β, 0.001; 95% CI, - 0.002; 0.002). CONCLUSIONS Television time and sleep duration are associated with cardiometabolic risk; adolescents with short sleep have higher cardiometabolic risk. In addition, age plays a moderating role in the relationship between TV time and cardiometabolic risk, indicating that in younger adolescents the relationship is stronger compared to older ones.

BACKGROUND/AIMS: The epidemiology of functional gastrointestinal disorders (FGIDs) in developed and developing countries involves a high prevalence of constipation and irritable bowel syndrome. This study examined the prevalence of functional gastrointestinal disorders in schoolchildren and adolescents in Colombia using the Rome III criteria. METHODS: A cross-sectional study was performed on Colombian children between 8 and 17 years old. The Spanish version of the Questionnaire on Pediatric Gastrointestinal Symptoms-Rome III Version self-report form was answered by students from two schools. The prevalence of FGID was calculated and correlation tests were conducted among the variables analyzed. RESULTS: A total of 864 children with a mean age of 12.5±2.5 years were analyzed; 50.7% were female. Two hundred and fifty-nine children (30%) had at least one FGID, and of these, 163 were female (62.9%). Sixty-nine children had two or more FGIDs (8%). Functional constipation was the most prevalent disorder (13.2%), followed in order by abdominal migraine (8.3%), irritable bowel syndrome (6.9%), and aerophagia (3.1%). A significantly higher prevalence of FGID was observed in females (p=0.000). No significant difference was observed between the age groups or type of school they attended. CONCLUSIONS: The overall prevalence of FGID in the sample was 30%, with functional constipation being the most common. These results are similar to those of other prevalence studies reported elsewhere.

OBJECTIVES: The objective of this case report is to introduce the development process, structure, characteristics, and effectiveness of the web database (DB) system developed for the hypertension management program in the primary health care setting in the low-income urban areas of Peru. METHODS: A Korean research team cooperated with a Peruvian IT startup company to develop a web DB system to improve the data management of the hypertension management program. The entire web application infrastructure was hosted using the Amazon Web Service. Two different web platforms were established for the user groups of health workers and researchers (program managers). RESULTS: A total of 2,827 program participants were registered in the web DB system until December 2017. Health professionals can input the participant data while providing consultation to the program participants, and the data is accumulated in the web DB in real time. Input errors or data loss is prevented by setting restrictions in the data entry system. During the 4-year project period, 7,696 hours of working time and USD 39,536.48 for data management were saved as the result of web DB system utilization. CONCLUSIONS: The developed web DB system contributed to improve the health condition of the health program participants by providing necessary information to the health professionals at the right time. This case report could be a reference for other researcher to develop web databases for their own context, especially in developing countries.

OBJECTIVES: Early initiation of breastfeeding (EIBF) is one of the most cost-effective strategies to reduce neonatal mortality. We sought to determine the prevalence and determinants of EIBF in Peru.METHODS: We performed a cross-sectional analytical study of the 2018 Peruvian Demographic and Family Health Survey as a secondary data source. In total, 19,595 children born during the 5 years prior to the survey were included in the study. The dependent variable (EIBF status), socio-demographic variables, and pregnancy-related variables were analyzed using a multivariate logistic regression model to identify the determinants of EIBF.RESULTS: The prevalence of EIBF in the study population was 49.7%. Cesarean deliveries were associated with a lower likelihood of EIBF (adjusted odds ratio [aOR], 0.06; 95% confidence interval [CI], 0.05 to 0.07) than were vaginal deliveries. Newborns born at public health centers (aOR, 1.37; 95% CI, 1.15 to 1.65) had a higher rate of EIBF than those not born at public or private health centers. Women from the jungle region (aOR, 2.51; 95% CI, 2.17 to 2.89) had higher odds of providing EIBF than those from the coast. Mothers with more than a secondary education (aOR, 0.65; 95% CI, 0.55 to 0.76) were less likely to breastfeed during the first hour of the newborn's life than women with primary or no education.CONCLUSIONS: More than half of Peruvian children do not breastfeed during the first hour after birth. The major determinants of EIBF status were the delivery mode and the region of maternal residence. Strategies are needed to promote early breastfeeding practices.

OBJECTIVES: To estimate the number and risk of imported infections resulting from people visiting Asian and Latin American countries.METHODS: The dataset of visitors to 5 Asian countries with dengue were analyzed for 2016 and 2017, and in the Philippines, Thailand and Vietnam, imported cases of zika virus infection were also reported. For zika virus, a single imported case was reported from Brazil in 2016, and 2 imported cases reported from the Maldives in 2017. To understand the transmissibility in 5 Southeast Asian countries, the estimate of the force of infection, i.e., the hazard of infection per year and the average duration of travel has been extracted. Outbound travel numbers were retrieved from the World Tourism Organization, including business travelers.RESULTS: The incidence of imported dengue in 2016 was estimated at 7.46, 15.00, 2.14, 4.73 and 2.40 per 100,000 travelers visiting Philippines, Indonesia, Thailand, Malaysia and Vietnam, respectively. Similarly, 2.55, 1.65, 1.53, 1.86 and 1.70 per 100,000 travelers in 2017, respectively. It was estimated that there were 60.1 infections (range: from 16.8 to 150.7 infections) with zika virus in Brazil, 2016, and 345.6 infections (range: from 85.4 to 425.5 infections) with zika virus in the Maldives, 2017.CONCLUSION: This study emphasizes that dengue and zika virus infections are mild in their nature, and a substantial number of infections may go undetected. An appropriate risk assessment of zika virus infection must use the estimated total size of infections.
