Item Meta-Research in Geriatric Surgery: Improving the Quality of Surgical Evidence for Older Persons in a Multidimensional-Scale Research Field(MDPI, 2024) Lozada Martinez, Ivan David; Hernandez Paez, David A.; Palacios Velasco, Isabela; Martinez Guevara, Darly; Liscano, YamilThe world is facing a significant demographic transition, with a substantial increase in the proportion of older persons, as well as long-lived persons (especially nonagenarians and centenarians). One of the popular beliefs is that old age is synonymous with disease and disability. However, the successful aging hypothesis suggests that those older persons with advanced chronological age who maintain their functional capacity derive from it a delay in biological aging, enhancing the quality of organic aging and regulation. Therefore, regardless of chronological age, even in cases of extreme longevity, those older adults with a successful aging phenotype and favorable functional capacity would be expected to have satisfactory post-surgical recovery with a low risk of morbidity and mortality. Currently, there is a significant gap between the availability of high-certainty surgical evidence that allows for evidence-based interventions applicable to the long-lived population—taking into account the actual conditioning factors of the health phenotype in older persons—and, above all, predictors of satisfactory post-surgical evolution. The application of meta-research to geriatric surgery emerges as a fundamental tool to address this knowledge gap and reveals opportunities and limitations that need to be resolved in the near future to establish evidence-based surgical care for older persons. The aim of this manuscript was to present a real and globally relevant scenario related to surgical care, addressing the longevity, the availability, and the quality of surgical evidence applicable to this population, and also to present variables to consider in analysis and future perspectives in research and meta-research in geriatric surgery.Item The Impact of Climatological Factors on the Incidence of Cutaneous Leishmaniasis (CL) in Colombian Municipalities from 2017 to 2019(MDPI, 2024) Muñoz Morales, Daniel; Franco Betancur, Oliva; Martinez Guevara, Darly; Liscano, Yamil; Suarez Daza, FernandaCutaneous leishmaniasis (CL) is a zoonotic disease caused by protozoa of the Leishmania genus, transmitted by vectors from the Phlebotominae subfamily. The interaction between the vector, reservoir, and parasite is susceptible to climate change. This study explores how temperature and rainfall influenced the incidence of CL in 15 Colombian municipalities between 2017 and 2019. Epidemiological data were obtained from Colombia’s Instituto Nacional de Salud, while climatological data came from the Instituto de Hidrología, Meteorología y Estudios Ambientales. Using Spearman’s rank correlation coefficient, we examined the relationships between monthly climatic variables and the cumulative incidence of CL, considering various lag times. The data were further analyzed using Locally Weighted Scatterplot Smoothing (LOWESS). Our findings reveal both significant positive and negative correlations, depending on locality and climate variables. LOWESS analysis indicates that while rainfall-related incidence remains stable, temperature impacts incidence in a parabolic trend. This study underscores the significant yet complex influence of climatic factors on CL incidence. The insights gained could aid public health efforts by improving predictive models and crafting targeted interventions to mitigate the disease’s impact, particularly in regions vulnerable to climate variability.Item Why is it important to implement meta-research in universities and institutes with medical research activities?(Frontiers Media SA, 2025-03-18) Lozada Martinez, Ivan David; Neira Rodado, Dionicio; Martinez Guevara, Darly; Cruz Soto, Hary Salome; Sanchez Echeverry, Maria Paula; Liscano, YamilIn recent years, there has been a growing concern over questionable practices and a lack of rigor in scientific activities, particularly in health and medical sciences. Universities and research institutes are key players in the development of science, technology, and innovation. Academic institutions, whose primary mission is to generate and disseminate knowledge, bear the responsibility in many parts of the world to act as consultants and guardians of scientific integrity in health research. Then, universities and research institutes must act as guardians of the research and technological development process, utilizing methodological and operational evaluation tools to validate the rigor and quality of medical research. Meta-research is defined as the research of research itself. Some of the most important specific objectives of meta-research include the assessment of research relevance, the evaluation of evidence validity, and the exploration of scientific integrity. A significant portion of evidence in the medical and health sciences literature has been found to be redundant, misleading, or inconsistent. Although this issue is of great importance in global health, discussions about practical and tangible solutions remain fragmented and limited. The aim of this manuscript is to highlight the significance of employing meta-research within universities and research institutes as a tool to monitor scientific rigor and promote responsible practices in medical research.
