Ítem Cigarette smoking and metabolic syndrome components: a cross-sectional study from Maracaibo City, Venezuela [version 1; referees: 1 approved with reservations](F1000 Research Ltda, 2018-05-22) Bermudez, Valmore; Olivar, Luis Carlos; Torres, Wheeler; Navarro, Carla; Gonzalez, Robys; Morocho, Alicia; Mindiola, Andres; Chacin, Maricarmen; Arias, Victor; Añez, Roberto; Salazar, Juan; Riaño Garzon, Manuel; Diaz Camargo, Edgar; Judith Bautista, Maria; Rojas, JoselynBackground: A growing body of evidence suggests that cigarette smoking can cause the onset of metabolic syndrome prior to cardiovascular diseases. Therefore, the objective of this study was to evaluate the relationship between smoking habit and metabolic syndrome components in an adult population from Maracaibo city, Venezuela. Methods: The Maracaibo City Metabolic Syndrome Prevalence Study is a descriptive, cross-sectional study with random and multi-stage sampling. In this sub-study, 2212 adults from both genders were selected. On the basis of their medical background, they were classified as smokers, non-smokers and former smokers. Metabolic syndrome was defined according to Harmonizing 2009 criteria, using population-specific abdominal circumference cut-off points. The association between risk factors was evaluated using a logistic regression model. Results: In the studied population, 14.8% were smokers, 15.4% were former smokers. In the multivariate analysis, the presence of metabolic syndrome (smokers: OR, 1.54; 95% CI, 1.11–2.14; p=0.010) and its components were related to cigarette smoking, with the exception of hyperglycemia. High blood pressure was inversely associated with current smoking status (smokers: OR, 0.70 (0.51–0.95); p=0.025).Ítem Intrinsic and environmental basis of aging: A narrative review(Elsevier Ltd., 2023) Navarro, Carla; Salazar, Juan; Díaz, María P.; Chacin, Maricarmen; Santeliz, Raquel; Vera, Ivana; D'Marco, Luis; Parra, Heliana; Bernal, Mary Carlota; Castro, Ana; Escalona, Daniel; García-Pacheco, Henry; Bermúdez, ValmoreLongevity has been a topic of interest since the beginnings of humanity, yet its aetiology and precise mechanisms remain to be elucidated. Aging is currently viewed as a physiological phenomenon characterized by the gradual degeneration of organic physiology and morphology due to the passage of time where both external and internal stimuli intervene. The influence of intrinsic factors, such as progressive telomere shortening, genome instability due to mutation buildup, the direct or indirect actions of age-related genes, and marked changes in epigenetic, metabolic, and mitochondrial patterns constitute a big part of its underlying endogenous mechanisms. On the other hand, several psychosocial and demographic factors, such as diet, physical activity, smoking, and drinking habits, may have an even more significant impact on shaping the aging process. Consequentially, implementing dietary and exercise patterns has been proposed as the most viable alternative strategy for attenuating the most typical degenerative aging changes, thus increasing the likelihood of prolonging lifespan and achieving successful aging.
