Item Benefits of pulmonary rehabilitation in patients with COPD with use and without the use of supplemental oxygen during exercise(Bentham Science Publishers, 2019-08-08) Betancourt Peña, Jhonatan; Ávila Valencia, Juan Carlos; Karim Assis, Jorge; Hurtado Gutiérrez, Hugo; Benavides Córdoba, VicenteObjective: To determine the effects of a pulmonary rehabilitation program in patients with COPD who use and do not use supplemental oxygen during exercise. Materials and Methods: Prospective longitudinal descriptive study on 59 patients with COPD who were part of a pulmonary rehabilitation program and who were classified into two groups: a group that required supplemental oxygen during rehabilitation and another that did not. Results: 31 patients were linked to the group that used oxygen during rehabilitation and 28 patients who did not use it. The average age was 69.1 ± 10.6 years old. The mMRC dyspnea decreased 0.7 ± 0.2 (p = 0.000) in the group that used oxygen and 0.8 ± 0.1 (p = 0.000) in the group that did not use it. The distance increased 45.9 meters ± 7.2 (p = 0.000) in the group that used oxygen and 65.2 meters ± 16.3 (p = 0.001) in the group that did not use it. Conclusion: Both groups showed significant improvements in dyspnea and aerobic capacity, however, there was a greater increase in the group that did not use oxygen.Item Comparison of clinical variables, functional capacity, anxiety/depression and quality of life in patients with COPD according to the GOLD 2018 classification(Ediciones Doyma, S.L., 2020-08-11) Betancourt Peña, J.; Artunduaga Landazabal, M. C.; Gil Ramírez, M. P.; León Atoy, K.; Ávila Valencia, Juan CarlosIntroducción: La Global Obstructive Lung Disease (GOLD) anualmente actualiza la guía para manejo de la EPOC, introduciendo cambios en la clasificación por letras, evaluación de síntomas o severidad de la obstrucción. Esto ha motivado el interés en indagar sobre las diferencias entre grupos en variables clínicas, calidad de vida relacionada con la salud (CVRS) y capacidad funcional. Objetivo: Determinar las diferencias en variables clínicas, supervivencia, de capacidad funcional, de ansiedad/depresión y CVRS en pacientes con enfermedad pulmonar obstructiva crónica (EPOC) de acuerdo a la clasificación GOLD 2018 en una clínica de Cali. Métodos: Estudio observacional, analítico y transversal; se incluyeron 128 pacientes con diagnóstico de EPOC divididos en 3 grupos: GOLD-B, GOLD-C y GOLD-D. Resultados: La edad media de los grupos fue 71 años y el 61% eran hombres. Las hospitalizaciones fueron más prevalentes en el grupo GOLD-C y GOLD-D, con 100% y 86% respectivamente, valor p < 0,001, con diferencias significativas en la supervivencia p < 0,001. La capacidad funcional evidenció una mayor distancia en el grupo GOLD-C con 344 m y la menor distancia para el grupo GOLD-B con 271 m, encontrando diferencia estadísticamente significativa. No se encontraron diferencias estadísticamente significativas en la ansiedad y la depresión. Al comparar los 3 grupos los pacientes GOLD-C tenían mejor CVRS en el cuestionario SGRQ; media de 37 ± 15, GOLD-B de 45 ± 16 y GOLD-D 55 ± 15, con valor p = 0,002. Conclusión: El grupo GOLD-C presentó mayor superviviencia, capacidad funcional y calidad de vida; por otra parte el grupo GOLD-D tuvo peor condición clínica, capacidad funcional y calidad de vida.Item Prevalence of Anti-SARS-CoV-2 Antibodies and Associated Factors Among Health Care Workers in Santiago De Cali, Colombia(Dove Medical Press Ltd, 2023-02-23) Osorio Toro, Luis Miguel; Bonilla Bonilla, Diana Marcela; Daza Arana, Jorge Enrique; Aristizábal, Juan Carlos; Ávila Valencia, Juan Carlos; Ramírez Marmolejo, RobertoPurpose: This study aims to determine the seroprevalence of coronavirus disease (COVID-19) among health care workers and describe the associated sociodemographic and labor features. Patients and Methods: An observational study with an analytical component was conducted at a clinic in Cali, Colombia. The sample size was 708 health workers and they were selected by stratified random sampling. A Bayesian analysis was developed to determine the raw and adjusted prevalence. A Poisson regression model was used to estimate the prevalence ratios. Results: Overall seroprevalence of COVID-19 among healthcare workers was 29%. Miscellaneous services workers, healthcare, and administrative workers, was 38%, 33%, and 32%, respectively. Factors related to seropositivity were having a contact with a COVID-19 patient for >120 minutes and being diagnosed with COVID-19 by laboratory tests. Conclusion: The present study shows a adjusted seroprevalence of 29% in health workers, indicating a high level of disease transmission and an increased risk of infection in this population group.Item Risk Factors for Postoperative Atrial Fibrillation in Myocardial Revascularization Surgery: A 15-Year Experience(MDPI, 2024) Bonilla Bonilla, Diana Marcela; Osorio Toro, Luis Miguel; Daza Arana, Jorge Enrique; Quintana Ospina, Jhon H.; Ávila Valencia, Juan Carlos; Lozada Ramos, HeilerBackground: Myocardial revascularization surgery (MRV) is a revascularization therapy for coronary artery disease aimed at improving survival conditions. Elderly patients with increased comorbidities undergoing MRV face challenges in preventing postoperative complications, including atrial fibrillation (AF), a common arrhythmia occurring in 40% of cases or even in 80% of cases if the procedure is combined with valve surgery. This study aimed to determine the risk factors associated with the appearance of postoperative AF (POAF) in patients undergoing isolated MRV. Methods: This is an epidemiological, retrospective, and analytical case–control study (90 cases and 360 controls). Results: Mortality within the group of patients who presented with POAF in the study population was 15.5%, and 9.44% in the control group. Logistic regression showed an association of AF with the presurgical variables age >60 years and urgent/emergency surgery and the postsurgical variables cardiogenic shock, blood transfusion, pulmonary edema, pleural effusion, orotracheal reintubation, and mechanical ventilation time. Conclusions: Strategies should be proposed for the timely identification of risk factors and postoperative complications related to AF onset to avoid the increased morbidity and mortality associated with this type of arrhythmia during the postoperative period.
