Early Diagnosis of Kidney Damage Associated with Tobacco Use: Preventive Application.

Although long-term smoking has been associated with chronic kidney disease, its effect on kidney function in early stages has not been clarified. Therefore, the proposed objectives were: (1) to identify subclinical kidney damage in smokers, through a panel of biomarkers; (2) to evaluate the progression of subclinical kidney damage after two years of consumption in these patients; and (3) study whether quitting smoking reduces kidney damage. A prospective study was carried out (patients recruited from a primary care centre and a clinical smoking unit). Kidney function was assessed using a panel of biomarkers and compared between smokers and non-smokers, taking into account potential risk factors for kidney damage. These results show, for the first time in the literature, the relationship between smoking and early (subclinical) kidney damage and provide a panel of biomarkers capable of detecting this condition (Neutrophil gelatinase-associated lipocalin, Kidney injury molecule-1, N-acetyl-beta-D-glucosaminidase, transferrin, and ganglioside-activating protein GM2). This study also indicates that subclinical damage is maintained when use continues, but can be reversed if patients stop smoking. The use of these biomarkers as diagnostic tools can be a preventive measure in the development of chronic kidney disease associated with smoking and in the prevention of acute events associated with potentially nephrotoxic pharmacological treatment in smokers.

Valoración por los estudiantes de la formación práctica de grado de Medicina. El caso de la Neumología / Valuation by the students of the practical training of degree of Medicine. The case of pneumology

INTRODUCCIÓN: La formación práctica en el grado de Medicina se imparte en los últimos cursos y está determinada por numerosos factores condicionantes, entre ellos, la formación MIR. En general, la evaluación de la formación práctica recibe mucha menos atención que la teórica, su calidad no es evaluada y el profesorado no recibe retroalimentación. El objetivo de nuestro estudio ha sido conocer la valoración que dan los alumnos a la formación práctica de Neumología después de una rotación de 3semanas, con el objetivo de obtener información para el proceso de mejora continua. MÉTODOS: El estudio incluye 2encuestas anónimas realizadas a los alumnos de grado en el mismo curso académico. Una interna, aplicada por el propio Servicio de Neumología y otra externa, por la Unidad de Evaluación de la Calidad Docente de la USAL. RESULTADOS: En la evaluación interna la opinión de los alumnos acerca de la calidad de la formación práctica es alta (8,26) y la utilidad percibida también es elevada (8,23), en una escala de 0 a 10, y no se observan diferencias por el hecho de que tenga lugar en cuarto, quinto o sexto curso. Estos resultados concuerdan con los obtenidos en la evaluación externa, con un valor medio de 4,56 en una escala de 0 a 5. Las preferencias de los alumnos durante su rotación por el servicio son las unidades de hospitalización y consultas, con menor valoración en las áreas técnicas. CONCLUSIONES: La calidad de la docencia práctica es un reto que es necesario evaluar para que los profesores dispongan de la retroalimentación (interna y externa) oportuna. La rotación por los servicios de Neumología constituye una oportunidad para la mejora de la percepción de la especialidad por los alumnos de grado. Es preciso reflexionar acerca de los contenidos de dicha rotación, buscando un equilibrio entre las áreas clínicas y las de técnicas

INTRODUCTION: Practical training for medical students is provided during the final years of study and is determined by several conditioning factors, including the MIR training that students receive simultaneously. In general, practical training evaluation receives much less attention than the theoretical one; its quality is not evaluated, and the professors do not receive feedback. The objective of our study was to determine how students value practical training in pulmonology rated the experience after completing a three-week rotation, in order to apply the information gained toward a process of continual improvement. METHODS: The study included 2anonymous surveys taken by medical students during the same academic year-one internal, prepared by the Department of Pneumology, itself, and another external one, prepared by the Evaluation Unit for Teaching Excellence at the University of Salamanca. RESULTS: On the internal evaluation, student opinions of their practical training ran high (8.26) and the perceived usefulness was also high (8.23), on a scale of 0 to 10 and no differences were noted according to whether the survey was taken during their fourth, fifth, or sixth year of study. These results agree with those obtained in the external evaluation with a mean value of 4.56 on a scale of 0 to 5. Student preferences during their rotation in the department were for hospitalization and consultation units, with the technical areas being lesser valued. CONCLUSIONS: Achieving and maintaining a high quality of practical training is a goal that should be consistently evaluated so that professors may receive feedback (internal and external). Rotations in the Department of Pneumology provide an opportunity to improve the perception that medical students have regarding this specialty. It is imperative to reflect upon the contents of these rotations, seeking a balance between clinical areas and technical areas

Cumplimiento de la oxigenoterapia crónica domiciliaria. Influencia del consumo de tabaco / Adherence to Long-Term Oxygen Therapy. Influence of Tobacco Use

Introducción: La oxigenoterapia crónica domiciliaria (OCD) es un tratamiento que exige una colaboración muy importante por parte de los pacientes debido al elevado número de horas que debe realizarse. Se conoce que existe un elevado nivel de incumplimiento entre los pacientes con OCD. El objetivo de nuestro estudio ha sido valorar el nivel de incumplimiento y la influencia del consumo de tabaco activo sobre el mismo. Material y métodos: Se ha realizado un control en el domicilio de los pacientes utilizando métodos directos e indirectos, tanto para valorar el nivel de cumplimiento como el de consumo de tabaco. Resultados: El nivel de incumplimiento detectado por métodos indirectos es del 22,6%, y por métodos directos es del 66,3%. El consumo de tabaco determinado por métodos indirectos es del 5,8% o del 8% dependiendo del método utilizado y del 16,2% cuando se establece un nivel de CO en aire exhalado ≥ 10 ppm como indicativo de fumador. El grupo de fumadores realiza un número de horas/día de oxigenoterapia significativamente menor (p < 0,001) que los no fumadores. Conclusiones: Existe un elevado nivel de incumplimiento terapéutico y un porcentaje importante de pacientes con OCD continúa fumando. Es preciso vigilar el cumplimiento, insistiendo en la necesidad de realizar bien la OCD, y se debe realizar también un esfuerzo añadido para ayudar a los fumadores con OCD a dejar de fumar, ya que mantener el consumo de tabaco contribuye a un mayor incumplimiento terapéutico

Introduction: Domiciliary oxygen therapy (DOT) is a treatment that requires a high level of cooperation from patients due to the time it takes every day. A high level of non-compliance has been determined among patients receiving DOT. The aim of our study was to assess the level of non-compliance and the influence of active tobacco consumption on compliance. Material and methods: Patients were monitored in the home using direct and indirect methods, to assess both compliance and tobacco consumption. Results: The level of non-compliance detected by indirect methods was 22.6%, and 66.3% by direct methods. Tobacco consumption determined by indirect methods was 5.8%-8%, depending on the method used, and 16.2% when CO in exhaled air ≥ 10ppm was established as an indicator of tobacco use. The group of smokers complied with oxygen therapy for a significantly fewer number of hours per day (P < .001) than non-smokers. Conclusions. There is a high level of therapeutic non-compliance and a significant percentage of patients receiving DOT continue to smoke. Compliance must be monitored, and the correct use of DOT must be emphasized. Additional efforts should also be made to help smokers with DOT to stop smoking, since continued smoking impacts negatively on therapeutic non-compliance

Utilidad del dispositivo portátil Piko-6 para la detección precoz de la enfermedad pulmonar obstructiva crónica en atención primaria / Usefulness of The Piko-6 Portable Device for Early COPD Detection in Primary Care

Introducción: La EPOC es una enfermedad de elevada prevalencia pero infradiagnosticada, debido a la escasa implantación de la espirometría forzada (EF) en atención primaria. Los microespirómetros, baratos y de manejo sencillo, que pueden medir FEV6 y FEV1/FEV6, podrían contribuir a reducir el infradiagnóstico. El objetivo del estudio ha sido validar el dispositivo Piko-6 para el cribado de la EPOC, demostrando una buena correlación con la EF convencional. Métodos: Se han realizado una EF y una determinación con Piko-6 a 155 pacientes susceptibles de padecer EPOC. Se han comparado las correlaciones, curvas ROC e índice de Youden con ambos métodos, considerando la EF como patrón de referencia. Resultados: Los coeficientes de correlación de FEV1, FVC y FEV6 y los cocientes FEV1/FVC y FEV1/FEV6 fueron de 0,87 (IC 95%: 0,836-0,909), 0,729 (IC 95%: 064-0,795) y 0,947 (IC 95%: 0,928-0,961) respectivamente. La curva ROC para el FEV1 determinado por Piko-6 alcanzó un área bajo la curva de 0,86 (IC 95%: 0,78-0,92). El índice de Youden para el punto de corte de 0,70 del FEV1/FEV6 fue 0,97. Conclusiones: El Piko-6 puede ser útil para el cribado de la EPOC en atención primaria. Sus determinaciones presentan buena correlación con las obtenidas mediante EF, especialmente el cociente FEV1/FEV6. Esto, junto a su bajo coste y facilidad de uso, puede contribuir a reducir el infradiagnóstico de la EPOC, aunque su rol exacto en el proceso diagnóstico está aún por determinar

Introduction: COPD is a highly prevalent but underdiagnosed disease, due to the limited availability of forced spirometry (FS) in primary care (PC). Microspirometers are inexpensive, easy-to-use devices that can measure FEV6 and FEV1/FEV6, and may help reduce underdiagnosis. The aim of this study was to validate the Piko-6 COPD screening device by demonstrating a good correlation with standard FS. Methods: FS and Piko-6 determinations were made in 155 patients suspected of having COPD. The correlations, ROC curves, and Youden's index of both methods were compared, taking FS as the gold standard. Results: FEV1, FVC and FEV6 correlation coefficients and FEV1/FVC and FEV1/FEV6 ratios were 0.87 (CI 0.836-0.909), 0.729 (CI 064-0.795) and 0.947 (95% CI 0.928-0.961), respectively. The ROC curve for FEV1 determined by Piko-6 achieved an area under the curve of 0.86 (95% CI: 0.78-0.92). Youden's index with a cut-off point of 0.70 for FEV1/FEV6 was 0.97. Conclusions: Piko-6 may be useful for COPD screening in PC. Measurements obtained with this device correlate well with those determined by FS, particularly the FEV1/FEV6 ratio. This, combined with its low cost and ease of use, may contribute to reducing COPD underdiagnosis, although its exact role in the diagnostic process remains to be determined

Tobacco and diabetes: clinical relevance and approach to smoking cessation in diabetic smokers. / Tabaco y diabetes: relevancia clínica y abordaje de la deshabituación tabáquica en pacientes con diabetes.

Smoking is, together with diabetes mellitus, one of the main risk factors for cardiovascular disease. Diabetic patients have unique features and characteristics, some of which are not well known, that cause smoking to aggravate the effects of diabetes and impose difficulties in the smoking cessation process, for which a specificand more intensive approach with stricter controls is required. This review details all aspects with a known influence on the interaction between smoking and diabetes, both as regards the increased risk of macrovascular and microvascular complications of diabetes and the factors with an impact on the results of smoking cessation programs. The treatment guidelines for these smokers, including the algorithms and drug treatment patterns which have proved most useful based on scientific evidence, are also discussed.

Tabaco y diabetes: relevancia clínica y abordaje de la deshabituación tabáquica en pacientes con diabetes / Tobacco and diabetes: clinical relevance and approach to smoking cessation in diabetic smokers

El tabaquismo es, junto con la diabetes mellitus, uno de los principales factores de riesgo cardiovascular. Los pacientes diabéticos presentan peculiaridades y características, algunas no bien conocidas, que hacen que el tabaquismo agrave los efectos de la diabetes y que el proceso de la deshabituación tabáquica en estos pacientes presente dificultades añadidas y que, por tanto, requiera un abordaje específico, más intensivo y con controles más rigurosos. En esta revisión se desgranan todos los aspectos conocidos que influyen en la interacción entre el tabaquismo y la diabetes, tanto en lo referente al incremento del riesgo de las complicaciones macrovasculares y microvasculares de la diabetes como a los factores que influyen en los resultados de los programas de deshabituación tabáquica. Así mismo se exponen las pautas de tratamiento de estos fumadores, incluyendo los algoritmos y pautas de tratamiento farmacológico que, basándose en evidencia científica, se han mostrado más eficaces (AU)
