    (2015-10-14) Smyth, Andrew; Teo, Koon; Rangarajan, Sumathy; O’Donnell, Martin J.; Zhang, Xiaohe; Rana, Punam; Leong, Darryl P.; Dagenais, Gilles; Seron, Pamela; Rosengren, Annika; Schutte, Aletta Elisabeth; Lopez-Jaramillo, Patricio; Oguz, Ayetkin; Chifamba, Jephat; Diaz, Rafael; Lear, Scott A.; Avezum, Alvaro; Kumar, Rajesh; Mohan, Viswanathan; Szuba, Andrzej; Wei, Li; Yang, Wang; Jian, Bo; McKee, Martin; Yusuf, Salim; The PURE (Prospective Urban Rural Epidemiology) Study investigators
    Background Alcohol consumption is proposed to be the third most important modifiable risk factor for death and disability. However, alcohol consumption has been associated with both benefits and harms, and previous studies were mostly done in high-income countries. We investigated associations between alcohol consumption and outcomes in a prospective cohort of countries at different economic levels in five continents. Methods We included information from 12 countries participating in the Prospective Urban Rural Epidemiological (PURE) study, a prospective cohort study of individuals aged 35–70 years. We used Cox proportional hazards regression to study associations with mortality (n=2723), cardiovascular disease (n=2742), myocardial infarction (n=979), stroke (n=817), alcohol-related cancer (n=764), injury (n=824), admission to hospital (n=8786), and for a composite of these outcomes (n=11 963). Findings We included 114 970 adults, of whom 12 904 (11%) were from high-income countries (HICs), 24 408 (21%) were from upper-middle-income countries (UMICs), 48 845 (43%) were from lower-middle-income countries (LMICs), and 28 813 (25%) were from low-income countries (LICs). Median follow-up was 4·3 years (IQR 3·0–6·0). Current drinking was reported by 36 030 (31%) individuals, and was associated with reduced myocardial infarction (hazard ratio [HR] 0·76 [95% CI 0·63–0·93]), but increased alcohol-related cancers (HR 1·51 [1·22–1·89]) and injury (HR 1·29 [1·04–1·61]). High intake was associated with increased mortality (HR 1·31 [1·04–1·66]). Compared with never drinkers, we identified significantly reduced hazards for the composite outcome for current drinkers in HICs and UMICs (HR 0·84 [0·77–0·92]), but not in LMICs and LICs, for which we identified no reductions in this outcome (HR 1·07 [0·95–1·21]; pinteraction<0·0001). Interpretation Current alcohol consumption had differing associations by clinical outcome, and differing associations by income region. However, we identified sufficient commonalities to support global health strategies and national initiatives to reduce harmful alcohol use.

    Análisis espacial de riesgo de morbilidad y mortalidad por COVID-19 en Europa y el Mediterráneo en el año 2020
    (2020-10-27) Andrades-Grassi, Jesús Enrique; Cuesta-Herrera, Ledyz; Bianchi-Pérez, Guillermo; Grassi, Hilda Cristina; Lopez-Hernandez, Juan Ygnacio; Torres-Mantilla, Hugo; Gaia
    Disease mapping seeks to represent the risk of a disease. This paper focuses on the spatial analysis of risk for pandemic COVID-19 in Europe and the Mediterranean. Morbidity and mortality data for 54 countries in ratio format were used. Two hypotheses were considered, the first one is that the data are homogeneous and the second one is that the ratios are defined in a heterogeneous manner requiring the stratification on the basis of covariables and the methodology of Jenks’ intervals. Spatial risk models were applied as well as methods for the representation of clusters. The results show that the best representation is obtained with the Poisson-Gamma Model under stratification. The variations in the ratios are due to the individual policies of each country for the management of the pandemic. The cluster analysis shows that there is a high mortality process in Eastern Europe. The behavior of the pandemic should be evaluated in the space-time process as well as in other heterogeneous and highly unequal regions.

    Association of bedtime with mortality and major cardiovascular events: an analysis of 112,198 individuals from 21 countries in the PURE study
    (Elsevier, 2021-04-05) Wang, Chuangshi; Hu, Bo; Rangarajan, Sumathy; Bangdiwala, Shrikant I.; Lear, Scott A.; Mohan, Viswanathan; Gupta, Rajeev; Alhabib, Khalid F.; Soman, Biju; Abat, Marc Evans M.; Rosengren, Annika; Lanas, Fernando; Avezum, Alvaro; Lopez-Jaramillo, Patricio; Diaz, Rafael; Yusoff, Khalid; Iqbal, Romaina; Chifamba, Jephat; Yeates, Karen; Zatońska, Katarzyna; Kruger, Iolanthe M.; Bahonar, Ahmad; Yusufali, AfzalHussein; Li, Wei; Yusuf, Salim; The Prospective Urban Rural Epidemiology (PURE) study investigators; Masira
    Objectives This study aimed to examine the association of bedtime with mortality and major cardiovascular events. Methods Bedtime was recorded based on self-reported habitual time of going to bed in 112,198 participants from 21 countries in the Prospective Urban Rural Epidemiology (PURE) study. Participants were prospectively followed for 9.2 years. We examined the association between bedtime and the composite outcome of all-cause mortality, non-fatal myocardial infarction, stroke and heart failure. Participants with a usual bedtime earlier than 10PM were categorized as ‘earlier’ sleepers and those who reported a bedtime after midnight as ‘later’ sleepers. Cox frailty models were applied with random intercepts to account for the clustering within centers. Results A total of 5633 deaths and 5346 major cardiovascular events were reported. A U-shaped association was observed between bedtime and the composite outcome. Using those going to bed between 10PM and midnight as the reference group, after adjustment for age and sex, both earlier and later sleepers had a higher risk of the composite outcome (HR of 1.29 [1.22, 1.35] and 1.11 [1.03, 1.20], respectively). In the fully adjusted model where demographic factors, lifestyle behaviors (including total sleep duration) and history of diseases were included, results were greatly attenuated, but the estimates indicated modestly higher risks in both earlier (HR of 1.09 [1.03–1.16]) and later sleepers (HR of 1.10 [1.02–1.20]). Conclusion Early (10 PM or earlier) or late (Midnight or later) bedtimes may be an indicator or risk factor of adverse health outcomes.

    (American Journal of Clinical Nutrition, 2020-04-01) Dehghan, Mahshid; Mente, Andrew; Rangarajan, Sumathy; Mohan, Viswanathan; Lear, Scott; Swaminathan, Sumathi; Wielgosz, Andreas; Seron, Pamela; Avezum, Alvaro; Lopez-Jaramillo, Patricio; Turbide, Ginette; Chifamba, Jephat; AlHabib, Khalid F.; Mohammadifard, Noushin; Szuba, Andrzej; Khatib, Rasha; Altuntas, Yuksel; Liu, Xiaoyun; Iqbal, Romaina; Rosengren, Annika; Yusuf, Rita; Smuts, Marius; Yusufali, AfzalHussein; Li, Ning; Diaz, Rafael; Yusoff, Khalid; Kaur, Manmeet; Soman, Biju; Ismail, Noorhassim; Gupta, Rajeev; Dans, Antonio; Sheridan, Patrick; Teo, Koon; Anand, Sonia S; Yusuf, Salim; Behalf of the PURE investigators; Everest
    ABSTRACT Background: Eggs are a rich source of essential nutrients, but they are also a source of dietary cholesterol. Therefore, some guidelines recommend limiting egg consumption. However, there is contradictory evidence on the impact of eggs on diseases, largely based on studies conducted in high-income countries. Objectives: Our aim was to assess the association of egg consumption with blood lipids, cardiovascular disease (CVD), and mortality in large global studies involving populations from low-, middle-, and high-income countries. Methods: We studied 146,011 individuals from 21 countries in the Prospective Urban Rural Epidemiology (PURE) study. Egg consumption was recorded using country-specific validated FFQs. We also studied 31,544 patients with vascular disease in 2 multinational prospective studies: ONTARGET (Ongoing Telmisartan Alone and in Combination with Ramipril Global End Point Trial) and TRANSCEND (Telmisartan Randomized Assessment Study in ACEI Intolerant Subjects with Cardiovascular Disease). We calculated HRs using multivariable Cox frailty models with random intercepts to account for clustering by study center separately within each study. Results: In the PURE study, we recorded 14,700 composite events (8932 deaths and 8477 CVD events). In the PURE study, after excluding those with history of CVD, higher intake of egg (≥7 egg/wk compared with <1 egg/wk intake) was not significantly associated with blood lipids, composite outcome (HR: 0.96; 95% CI: 0.89, 1.04; P-trend = 0.74), total mortality (HR: 1.04; 95% CI: 0.94, 1.15; P-trend = 0.38), or major CVD (HR: 0.92; 95% CI: 0.83, 1.01; P-trend = 0.20). Similar results were observed in ONTARGET/TRANSCEND studies for composite outcome (HR 0.97; 95% CI: 0.76, 1.25; P-trend = 0.09), total mortality (HR: 0.88; 95% CI: 0.62, 1.24; P-trend = 0.55), and major CVD (HR: 0.97; 95% CI: 0.73, 1.29; P-trend = 0.12). Conclusions: In 3 large international prospective studies including ∼177,000 individuals, 12,701 deaths, and 13,658 CVD events from 50 countries in 6 continents, we did not find significant associations between egg intake and blood lipids, mortality, or major CVD events. The ONTARGET and TRANSCEND trials were registered at clinicaltrials.gov as NCT00153101. The PURE trial was registered at clinicaltrials.gov as NCT03225586. Am J Clin Nutr 2020;111:795–803.

    (European Society of Cardiology, 2019-05-21) Wang, Chuangshi; Bangdiwala, Shrikant I.; Rangarajan, Sumathy; Lear, Scott A.; AlHabib, Khalid F.; Mohan, Viswanathan; Koon, Teo; Poirier, Paul; Tse, Lap Ah; Liu, Zhiguang; Rosengren, Annika; Kumar, Rajesh; Lopez-Jaramillo, Patricio; Yusoff, Khalid; Monsef, Nahed; Krishnapillai, Vijayakumar; Ismail, Noorhassim; Seron, Pamela; Dans, Antonio; Kruger, Lanthé; Yeates, Karen; Leach, Lloyd; Yusuf, Rita; Orlandini, Andres; Wolyniec, Maria; Bahonar, Ahmad; Mohan, Indu; Khatib, Rasha; Temizhan, Ahmet; Li, Wei; Yusuf, Salim; On behalf of the Prospective Urban Rural Epidemiology (PURE) study investigators; Everest
    Aims To investigate the association of estimated total daily sleep duration and daytime nap duration with deaths and major cardiovascular events. Methods and results We estimated the durations of total daily sleep and daytime naps based on the amount of time in bed and self-reported napping time and examined the associations between them and the composite outcome of deaths and major cardiovascular events in 116 632 participants from seven regions. After a median follow-up of 7.8 years, we recorded 4381 deaths and 4365 major cardiovascular events. It showed both shorter (≤6 h/day) and longer (>8 h/day) estimated total sleep durations were associated with an increased risk of the composite outcome when adjusted for age and sex. After adjustment for demographic characteristics, lifestyle behaviours and health status, a J-shaped association was observed. Compared with sleeping 6–8 h/day, those who slept ≤6 h/day had a non-significant trend for increased risk of the composite outcome [hazard ratio (HR), 1.09; 95% confidence interval, 0.99–1.20]. As estimated sleep duration increased, we also noticed a significant trend for a greater risk of the composite outcome [HR of 1.05 (0.99–1.12), 1.17 (1.09–1.25), and 1.41 (1.30–1.53) for 8–9 h/day, 9–10 h/day, and >10 h/day, Ptrend < 0.0001, respectively]. The results were similar for each of all-cause mortality and major cardiovascular events. Daytime nap duration was associated with an increased risk of the composite events in those with over 6 h of nocturnal sleep duration, but not in shorter nocturnal sleepers (≤6 h). Conclusion Estimated total sleep duration of 6–8 h per day is associated with the lowest risk of deaths and major cardiovascular events. Daytime napping is associated with increased risks of major cardiovascular events and deaths in those with >6 h of nighttime sleep but not in those sleeping ≤6 h/night.

    (American Society for Nutrition, 2020-05-20) De Souza, Russell J; Dehghan, Mahshid; Mente, Andrew; Bangdiwala, Shrikant I; Ahmed, Suad Hashim; Alhabib, Khalid F; Altuntas, Yuksel; Basiak-Rasała, Alicja; Dagenais, Gilles-R; Diaz, Rafael; Amma, Leela Itty; Kelishadi, Roya; Khatib, Rasha; Lear, Scott A; Lopez-Jaramillo, Patricio; Mohan, Viswanathan; Poirier, Paul; Rangarajan, Sumathy; Rosengren, Annika; Ismail, Rosnah; Swaminathan, Sumathi; Wentzel-Viljoen, Edelweiss; Yeates, Karen; Yusuf, Rita; Teo, Koon; Anand, Sonia S; Yusuf, Salim; PURE Study Investigators; Everest
    Background: The association of nuts with cardiovascular disease and deaths has been investigated mostly in Europe, the USA, and East Asia, with few data available from other regions of the world or from low- and middle-income countries. Objective: To assess the association of nuts with mortality and cardiovascular disease (CVD). Methods: The Prospective Urban Rural Epidemiology study is a large multinational prospective cohort study of adults aged 35–70 y from 16 low-, middle-, and high-income countries on 5 continents. Nut intake (tree nuts and ground nuts) was measured at the baseline visit, using country-specific validated FFQs. The primary outcome was a composite of mortality or major cardiovascular event [nonfatal myocardial infarction (MI), stroke, or heart failure]. Results: We followed 124,329 participants (age = 50.7 y, SD = 10.2; 41.5% male) for a median of 9.5 y. We recorded 10,928 composite events [deaths (n = 8,662) or major cardiovascular events (n = 5,979)]. Higher nut intake (>120 g per wk compared with <30 g per mo) was associated with a lower risk of the primary composite outcome of mortality or major cardiovascular event [multivariate HR (mvHR): 0.88; 95% CI: 0.80, 0.96; P-trend = 0.0048]. Significant reductions in total (mvHR: 0.77; 95% CI: 0.69, 0.87; Ptrend <0.0001), cardiovascular (mvHR: 0.72; 95% CI: 0.56, 0.92; Ptrend = 0.048), and noncardiovascular mortality (mvHR: 0.82; 95% CI: 0.70, 0.96; P-trend = 0.0046) with a trend to reduced cancer mortality (mvHR: 0.81; 95% CI: 0.65, 1.00; P-trend = 0.081) were observed. No significant associations of nuts were seen with major CVD (mvHR: 0.91; 95% CI: 0.81, 1.02; P-trend = 0.14), stroke (mvHR: 0.98; 95% CI: 0.84, 1.14; P-trend = 0.76), or MI (mvHR: 0.86; 95% CI: 0.72, 1.04; P-trend = 0.29). Conclusions: Higher nut intake was associated with lower mortality risk from both cardiovascular and noncardiovascular causes in low-, middle-, and high-income countries.

    Association of urinary sodium excretion with blood pressure and cardiovascular clinical events in 17,033 Latin americans
    (2016-07) Lamelas, Pablo M.; Mente, Andrew; Diaz, Rafael; Orlandini, Andres; Avezum, Alvaro; Oliveira, Gustavo; Lanas, Fernando; Seron, Pamela; Lopez-Jaramillo, Patricio; Camacho López, Paul Anthony; O’Donnell, Martin J.; Rangarajan, Sumathy; Teo, Koon; Yusuf, Salim
    BACKGROUND: Information on actual sodium intake and its relationships with blood pressure (BP) and clinical events in South America is limited. The aim of this cohort study was to assess the relationship of sodium intake with BP, cardiovascular (CV) events, and mortality in South America. METHODS: We studied 17,033 individuals, aged 35–70 years, from 4 South American countries (Argentina, Brazil, Chile, and Colombia). Measures of sodium excretion, estimated from morning fasting urine, were used as a surrogate for daily sodium intake. We measured BP and monitored the composite outcome of death and major CV events. RESULTS: Overall mean sodium excretion was 4.70±1.43g/day. A positive, nonuniform association between sodium and BP was detected, with a significant steeper slope for the relationship at higher sodium excretion levels ( P < 0.001 for interaction). With a median follow-up of 4.7 years, the primary composite outcome (all-cause death, myocardial infarction, stroke, or heart failure) occurred in 568 participants (3.4%). Compared with sodium excretion of 5–6g/day (reference group), participants who excreted >7g/day had increased risks of the primary outcome (odds ratio (OR) 1.73; 95% confidence interval (CI) 1.24 to 2.40; P < 0.001), as well as death from any cause (OR 1.87; 95% CI 1.23 to 2.83; P = 0.003) and major CV disease (OR 1.77; 95% CI 1.12 to 2.81; P = 0.014). Sodium excretion of <3g/day was associated with a statistically nonsignificant increased risk of the primary outcome (OR 1.20; 95% CI 0.86 to 1.65; P = 0.26) and death from any cause (OR 1.25; 95% CI 0.81 to 1.93; P = 0.29), and a significant increased risk of major CV disease (OR 1.50; 95% CI 1.01 to 2.24; P = 0.048), as compared to the reference group. CONCLUSIONS: Our results support a positive, nonuniform association between estimated urinary sodium excretion and BP, and a possible J-shaped pattern of association between sodium excretion over the entire range and clinical outcomes.

    Determinación del Potencial Tóxico y de Unión a Receptores de Membrana de Péptidos Derivados de 8Cry11Aa en Aedes aegypti
    (Universidad de Santander, 2023-01-25) Méndez-Bayona, Gabriela; Suárez-Barrera, Miguel Orlando; Valdivieso-Quintero, Wilfredo; Farfán-García, Ana Elvira; Biología Molecular y Biotecnología
    Bacillus thuringiensis (Bt) es una bacteria Gram positiva formadora de esporas, que se utiliza en el mayor de los casos como biopesticida debido a su capacidad para producir proteínas insecticidas, este microorganismo contiene una gran variedad toxinas durante sus fases de crecimiento, sin embargo, las más conocidas son las δ -endotoxinas, entre ellas la proteína Cry11Aa, tóxica para el vector Aedes aegypti, responsable de la trasmisión de enfermedades como dengue, zika y Chikungunya. En el grupo de investigación de Biología Molecular y Biotecnología de la UDES, tras el desarrollo de un barajado molecular de ADN, se obtuvo la proteína 8Cry11Aa, la cual presento un aumento de toxicidad en comparación con las parentales. A partir de lo anterior, se generó un interés en conocer más acerca de esta variante, es por lo cual en el presente trabajo se tuvo como objetivo realizar una síntesis de las regiones de la proteína, en donde se generaron seis secuencias cortas a los cuales se le efectuaron mutaciones puntuales con el fin de otorgar mejores características que permitieran la unión al receptor de la membrana del insecto. Tras las evaluaciones realizadas de la interacción péptido-receptor por medio de Docking molecular y las pruebas de letalidad. El modelo 4299 mostró un 100 % de mortalidad en una concentración de 100 µM, la secuencia contaba con dos modificaciones específicas (triptófano y tirosina) en las posiciones 8 y 13 del péptido, así como la adición de cisteínas. Los resultados obtenidos permitieron concluir que las mutaciones probablemente estuvieron relacionadas un aumento estabilidad y adhesión a las membranas del intestino que permitieron generar una mayor toxicidad por la formación de puentes disulfuro y el aumento de la hidrofobicidad en las regiones interfaciales de las bicapas lipídicas de la membrana del insecto.

    The effect of physical activity on mortality and cardiovascular disease in 130 000 people from 17 high-income, middle-income, and low-income countries: The PURE study
    (2017-12) Lear, Scott A.; Hu, Weihong; Rangarajan, Sumathy; Gasevic, Danijela; Leong, Darryl P.; Iqbal, Romaina; Casanova, Amparo; Swaminathan, Sumathi; Anjana, Ranjit Mohan; Kumar, Rajesh; Rosengren, Annika; Wei, Li; Yang, Wang; Chuangshi, Wang; Huaxing, Liu; Nair, Sanjeev; Diaz, Rafael; Swidon, Hany; Gupta, Rajeev; Mohammadifard, Noushin; Lopez-Jaramillo, Patricio; Oguz, Aytekin; Zatonska, Katarzyna; Seron, Pamela; Avezum, Alvaro; Poirier, Paul P.; Teo, Koon; Yusuf, Salim
    Background: Physical activity has a protective effect against cardiovascular disease (CVD) in high-income countries, where physical activity is mainly recreational, but it is not known if this is also observed in lower-income countries, where physical activity is mainly non-recreational. We examined whether different amounts and types of physical activity are associated with lower mortality and CVD in countries at different economic levels. Methods: In this prospective cohort study, we recruited participants from 17 countries (Canada, Sweden, United Arab Emirates, Argentina, Brazil, Chile, Poland, Turkey, Malaysia, South Africa, China, Colombia, Iran, Bangladesh, India, Pakistan, and Zimbabwe). Within each country, urban and rural areas in and around selected cities and towns were identified to reflect the geographical diversity. Within these communities, we invited individuals aged between 35 and 70 years who intended to live at their current address for at least another 4 years. Total physical activity was assessed using the International Physical Activity Questionnaire (IPQA). Participants with pre-existing CVD were excluded from the analyses. Mortality and CVD were recorded during a mean of 6·9 years of follow-up. Primary clinical outcomes during follow-up were mortality plus major CVD (CVD mortality, incident myocardial infarction, stroke, or heart failure), either as a composite or separately. The effects of physical activity on mortality and CVD were adjusted for sociodemographic factors and other risk factors taking into account household, community, and country clustering. Findings: Between Jan 1, 2003, and Dec 31, 2010, 168 916 participants were enrolled, of whom 141 945 completed the IPAQ. Analyses were limited to the 130 843 participants without pre-existing CVD. Compared with low physical activity (<600 metabolic equivalents [MET] × minutes per week or <150 minutes per week of moderate intensity physical activity), moderate (600–3000 MET × minutes or 150–750 minutes per week) and high physical activity (>3000 MET × minutes or >750 minutes per week) were associated with graded reduction in mortality (hazard ratio 0·80, 95% CI 0·74–0·87 and 0·65, 0·60–0·71; p<0·0001 for trend), and major CVD (0·86, 0·78–0·93; p<0·001 for trend). Higher physical activity was associated with lower risk of CVD and mortality in high-income, middle-income, and low-income countries. The adjusted population attributable fraction for not meeting the physical activity guidelines was 8·0% for mortality and 4·6% for major CVD, and for not meeting high physical activity was 13·0% for mortality and 9·5% for major CVD. Both recreational and non-recreational physical activity were associated with benefits. Interpretation: Recreational and non-recreational physical activity was associated with a lower risk of mortality and CVD events in individuals from low-income, middle-income, and high-income countries. Increasing physical activity is a simple, widely applicable, low cost global strategy that could reduce deaths and CVD in middle age.

    Factores Asociados con la Mortalidad y Pérdida de los Pacientes Intervenidos por Cardiopatía Congénita Compleja en Primer Periodo Interestadío en la Fundación Cardiovascular de Colombia desde 2015 a 2019
    (Bucaramanga : Universidad de Santander, 2021, 2021-03-04) Mantilla Durán, Laura Carolina; Castro Monsalve, Javier-Mauricio; Uribe Caputi, Juan-Carlos; Bermon Angarita, Anderson
    A los niños con cardiopatías congénitas complejas se les realiza una serie de procedimientos quirúrgicos. El periodo “interestadío”, describe el tiempo en el que se da egreso hospitalario y permanecen en sus hogares en espera de su segunda cirugía. El objetivo de este estudio fue identificar la tasa de mortalidad y factores asociados en niños intervenidos en la FCV, que se encontraban en interestadío para el 2015-2019. También identificar pacientes perdidos en el seguimiento. Estudio de cohorte retrospectivo, 173 pacientes cumplían con criterios de inclusión; la población estudio está compuesta 56,1% (IC 95% 48,3;63,6) por niños; mediana de edad de 45 días. No se logró recuperar información de su estado actual en 45 niños, encontrando una mortalidad de 13,2% (17/128 pacientes) [IC95% 7,9; 20,4] y pérdidas al seguimiento 26% (45/173 pacientes) [IC95% 19,6; 33,2]. Como factores asociados a la mortalidad, ser de procedencia rural (58,8% vs 18%), y pertenecer régimen subsidiado (15 (88,2) vs 56 (50,5%) p=0,014). De las complicaciones postoperatorias, la enterocolitis necrotizante (32 (28,8%) vs 9 (52,9%) p=0,056, y la falla renal con diálisis 12 (10,8%) vs 5 (29,4) p=0,051 presentaron diferencias significativas. El análisis multivariado demostró que los factores de riesgo para mortalidad incluyeron residencia rural ([RR] 3,14; [IC] del 95%: 1,80- 5,50; p=0), Algún grado de desnutrición ( [RR] 2,51; [IC] del 95%: 1,38;4,57; p=0,003) Anomalía especial heterotaxia ([RR] 2,92; [IC] 95%: 1,49;5,7; p=0,002) Situs inversus ([RR] 8,27: [IC] del 95%: 2,88;23,77; p=0,007), enterocolitis necrotizante ([RR] 8,84 [IC] 95%: 3,20;24,43; p=0). Para los niños perdidos en el seguimiento tuvo significancia estadística proceder de zona rural p=0,00, pertenecer al régimen subsidiado p=0,02. La mortalidad interestadío es alta, se identifican factores potencialmente modificables, lo que justifica un seguimiento estricto, vigilancia en casa y evitar la pérdida. Estos esfuerzos podrían disminuir la mortalidad en un futuro.

    Factores de riesgo de enfermedad cardiovascular en funcionarios administrativos de una Clínica de CUCUTA, 2020
    (Cúcuta, Universidad de Santander, 2020, 2020-07-03) Ramírez Romero, Lida Marcela; Ávila Quintero, Diego Andrés; Hernández Estupiñán, Mónica-Dayana.; Messier Riaño, Sandra-Patricia.
    Las enfermedades cardiovasculares son la principal causa de mortalidad y morbilidad a nivel internacional, cobrando la vida de miles de millones de personas y siendo un causante de diferentes limitaciones funcionales en la sociedad. Determinar los factores de riesgo de enfermedad cardiovascular en funcionarios administrativos de una Clínica de Cúcuta. Enfoque cuantitativo y tipo descriptivo y transversal usando como población y muestra por medio de un censo, se tomará un rango de edad de 18 a 65 años con 150 personas entre hombres y mujeres que laboran en el campo administrativo que por fuentes primarias eran sujetos de prioridad. Los instrumentos contaron con la fortaleza de ser de fácil aplicación y el registro en la base de datos facilito la organización y compresión de los resultados. Con base en los resultados obtenidos los cuales mostraron que la mayoría de los sujetos de estudio eran mujeres con edades entre los 30 y 40 años, que finalmente según las tablas de predicción del riesgo de la OMS/ISH obtuvieron un nivel de riesgo. Las estadísticas no muestran mejora a través de los años y la realidad del contexto del Norte de Santander no está muy lejana a dichas cifras. En conclusión, este tipo de análisis permitió conocer y estratificar el riesgo cardiovascular según las características propias de cada individuo, se evidencio que en mayor proporcionalidad los trabajadores de una Clínica de Cúcuta se encuentran en bajo riesgo cardiovascular.

    Background Most data on mortality and prognostic factors in patients with heart failure come from North America and Europe, with little information from other regions. Here, in the International Congestive Heart Failure (INTERCHF) study, we aimed to measure mortality at 1 year in patients with heart failure in Africa, China, India, the Middle East, southeast Asia and South America; we also explored demographic, clinical, and socioeconomic variables associated with mortality. Methods We enrolled consecutive patients with heart failure (3695 [66%] clinic outpatients, 2105 [34%] hospital in patients) from 108 centres in six geographical regions. We recorded baseline demographic and clinical characteristics and followed up patients at 6 months and 1 year from enrolment to record symptoms, medications, and outcomes. Time to death was studied with Cox proportional hazards models adjusted for demographic and clinical variables, medications, socioeconomic variables, and region. We used the explained risk statistic to calculate the relative contribution of each level of adjustment to the risk of death. Findings We enrolled 5823 patients within 1 year (with 98% follow-up). Overall mortality was 16·5%: highest in Africa (34%) and India (23%), intermediate in southeast Asia (15%), and lowest in China (7%), South America (9%), and the Middle East (9%). Regional differences persisted after multivariable adjustment. Independent predictors of mortality included cardiac variables (New York Heart Association Functional Class III or IV, previous admission for heart failure, and valve disease) and non-cardiac variables (body-mass index, chronic kidney disease, and chronic obstructive pulmonary disease). 46% of mortality risk was explained by multivariable modelling with these variables; however, the remainder was unexplained. Interpretation Marked regional differences in mortality in patients with heart failure persisted after multivariable adjustment for cardiac and non-cardiac factors. Therefore, variations in mortality between regions could be the result of health-care infrastructure, quality and access, or environmental and genetic factors. Further studies in large, global cohorts are needed. Funding The study was supported by Novartis.

    Influencia de la rehabilitación cardíaca sobre la tasa de re-hospitalización en pacientes con infarto agudo de miocardio, Santander, Colombia
    (2012-07) Naranjo Estupiñan, Néstor F.; Díaz Quijano, Fredi Alexander; García, Ronald G.
    The influence of cardiac rehabilitation on acute myocardial infarction patients’ readmission rates in Santander, Colombia Objective Estimating the effect of post-infarction cardiac rehabilitation (CR) on readmission/re-hospitalization rates according to intervention level. Method This was a prospective cohort study of patients diagnosed as suffering acute myocardial infarction (AMI). Data concerning infarction severity, previous illness, medical history, hospital course, Killip classification, length of hospital stay and condition on discharge. Medical records and telephone contact were used to confirm whether a patient had received CR and ascertain pertinent components. Follow-up was extended to one year. Results 96 AMI patients of both genders were included; information about CR was available for 72 of them,5 of whom had received CR based only on physical activity. 49 patients received complete CR based on education, physical activity, psychological and nutritional assessment. 18 patients had not received CR. One death and 10 new admissions/hospitalizations were recorded during follow-up. A Poisson regression model showed that patients who had received CR based only on physical activity presented significantly higher re-hospitalization rates than patients who had received a complete CR scheme (rate ratio 5.89:1.14-30.4995 % CI; p=0.04). Conclusions A multidisciplinary approach must bead opted to CR involving physical activity, education and psychological and nutritional assessment.

    The role of environment and epigenetics in hypertension
    (2013) Lopez-Jaramillo, Patricio; Camacho López, Paul Anthony; Forero Naranjo, Leonardo
    Many environmental risk factors associated with industrialization and urbanization, such as obesity, high dietary salt intake, excessive alcohol consumption, social stress and the aging population, are recognized as important contributory factors to the increases in blood pressure.

    Objective  Recent European Guidelines for Diabetes, Prediabetes and Cardiovascular Diseases introduced a shift in managing patients with type 2 diabetes at high risk for or established cardiovascular (CV) disease by recommending GLP-1 receptor agonists and SGLT-2 inhibitors as initial glucose-lowering therapy. This is questioned since outcome trials of these drug classes had metformin as background therapy. In this post hoc analysis, the effect of dulaglutide on CV events was investigated according to the baseline metformin therapy by means of a subgroup analysis of the Researching Cardiovascular Events with a Weekly Incretin in Diabetes (REWIND) trial. Research design and methods  Patients in REWIND (n = 9901; women: 46.3%; mean age: 66.2 years) had type 2 diabetes and either a previous CV event (31%) or high CV risk (69%). They were randomized (1:1) to sc. dulaglutide (1.5 mg/weekly) or placebo in addition to standard of care. The primary outcome was the first of a composite of nonfatal myocardial infarction, nonfatal stroke, and death from cardiovascular or unknown causes. Key secondary outcomes included a microvascular composite endpoint, all-cause death, and heart failure. The effect of dulaglutide in patients with and without baseline metformin was evaluated by a Cox regression hazard model with baseline metformin, dulaglutide assignment, and their interaction as independent variables. Adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated by a Cox regression model with adjustments for factors differing at baseline between people with vs. without metformin, identified using the backward selection. Results  Compared to patients with metformin at baseline (n = 8037; 81%), those without metformin (n = 1864; 19%) were older and slightly less obese and had higher proportions of women, prior CV events, heart failure, and renal disease. The primary outcome occurred in 976 (12%) participants with baseline metformin and in 281 (15%) without. There was no significant difference in the effect of dulaglutide on the primary outcome in patients with vs. without metformin at baseline [HR 0.92 (CI 0.81–1.05) vs. 0.78 (CI 0.61–0.99); interaction P = 0.18]. Findings for key secondary outcomes were similar in patients with and without baseline metformin. Conclusion  This analysis suggests that the cardioprotective effect of dulaglutide is unaffected by the baseline use of metformin therapy.

    (2014-08-14) O’Donnell, Martin J.; Mente, Andrew; Rangarajan, Sumathy; McQueen, Matthew J.; Wang, Xingyu; Liu, Lisheng; Yan, Hou; Lee, Shun Fu; Mony, Prem; Devanath, Anitha; Rosengren, Annika; Lopez-Jaramillo, Patricio; Diaz, Rafael; Avezum, Alvaro; Lanas, Fernando; Yusoff, Khalid; Iqbal, Romaina; Ilow, Rafal; Mohammadifard, Noushin; Gulec, Sadi; Yusufali, Afzalhussein; Kruger, Lanthe; Yusuf, Rita; Chifamba, Jephat; Kabali, Conrad; Dagenais, Gilles; Lear, Scott A.; Teo, Koon; Yusuf, Salim; The PURE (Prospective Urban Rural Epidemiology) Study investigators
    BACKGROUND The optimal range of sodium intake for cardiovascular health is controversial. METHODS We obtained morning fasting urine samples from 101,945 persons in 17 countries and estimated 24-hour sodium and potassium excretion (used as a surrogate for intake). We examined the association between estimated urinary sodium and potassium excretion and the composite outcome of death and major cardiovascular events. RESULTS The mean estimated sodium and potassium excretion were 4.93 g per day and 2.12 g per day, respectively. With a mean follow-up of 3.7 years, the composite outcome occurred in 3317 participants (3.3%). As compared with an estimated sodium excretion of 4.00 to 5.99 g per day (reference range), a higher estimated sodium excretion (≥7.00 g per day) was associated with an increased risk of the composite outcome (odds ratio, 1.15; 95% confidence interval [CI], 1.02 to 1.30), as well as increased risks of death and major cardiovascular events considered separately. The association between a high estimated sodium excretion and the composite outcome was strongest among participants with hypertension (P=0.02 for interaction). As compared with the reference range, an estimated sodium excretion that was below 3.00 g per day was also associated with an increased risk of the composite outcome (odds ratio, 1.27; 95% CI, 1.12 to 1.44). As compared with an estimated potassium excretion that was less than 1.50 g per day, higher potassium excretion was associated with a reduced risk of the composite outcome. CONCLUSIONS In this study in which sodium intake was estimated on the basis of measured urinary excretion, an estimated sodium intake between 3 g per day and 6 g per day was associated with a lower risk of death and cardiovascular events, as compared with either a higher or lower estimated level of intake. As compared with an estimate potassium excretion that was less than 1.50 g per day, higher potassium excretion was associated with a lower risk of death and cardiovascular events.
