Effectiveness of Twitter Threads to Improve Medical Student Electrocardiogram (ECG) Reading-Skills. The TwittUVa-ECG Non-Randomized Pre-Post Study.

Introduction: social media is increasingly used in medical education, but its real educational effectiveness is unclear. In this study we assess the effectiveness of Twitter threads (TTS) in improving electrocardiogram (ECG) basic reading skills (ECGBRS). Materials and Methods: Seven TTS describing ECGBRS were published from October 28, 2021, to November 24, 2021. Tests were used to assess medical students ECGBRS pre and post intervention. All third and sixth-year medical students were invited to participate. Sixty-three students were enrolled (33 third year and 30 sixth year). Nine (14.3%) participants dropped out. Results: Sixth year medical students had higher ECGBRS at baseline. The number of correct items increased after the Twitter intervention; median correct pre-test items were 20 out of 56, (interquartile range (IQR) 14-23), and median post-test were 29 out of 56, (IQR 21-36) (p < 0.001). The improvement in sixth year students was greater than for third year students; 10 more correct items (IQR 4-14) vs. 7 (IQR 1-14) items (p = 0.045). The more TTS followed, the greater the improvement in ECGBRS (p = 0.004). The QRS axis calculation was the ECG reading skill with the lowest scores. Most medical students were definitely (35%) or very probably (46%) interested in repeating another on-line learning experience and found the TTS extremely (39%) or very (46%) interesting. Conclusions: The use of specifically designed TTS was associated with improvement in medical students' interpretation of ECGs. The effectiveness of the threads was higher in the final years of medical school when basic skills had already been acquired.

LDL particle size and composition and incident cardiovascular disease in a South-European population: The Hortega-Liposcale Follow-up Study.

BACKGROUND: The association of low-density lipoprotein (LDL) particle composition with cardiovascular risk has not been explored before. The aim was to evaluate the relationship between baseline LDL particle size and composition (proportions of large, medium and small LDL particles over their sum expressed as small-LDL %, medium-LDL % and large-LDL %) and incident cardiovascular disease in a population-based study. METHODS: Direct measurement of LDL particles was performed using a two-dimensional NMR-technique (Liposcale®). LDL cholesterol was assessed using both standard photometrical methods and the Liposcale® technique in a representative sample of 1162 adult men and women from Spain. RESULTS: The geometric mean of total LDL particle concentration in the study sample was 827.2 mg/dL (95% CI 814.7, 839.8). During a mean follow-up of 12.4 ±â€¯3.3 years, a total of 159 events occurred. Medium LDL particles were positively associated with all cardiovascular disease, coronary heart disease (CHD) and stroke after adjustment for traditional risk factors and treatment. Regarding LDL particle composition, the multivariable adjusted hazard ratios for CHD for a 5% increase in medium and small LDL % by a corresponding decrease of large LDL % were 1.93 (1.55, 2.39) and 1.41 (1.14, 1.74), respectively. CONCLUSIONS: Medium LDL particles were associated with incident cardiovascular disease. LDL particles showed the strongest association with cardiovascular events when the particle composition, rather than the total concentration, was investigated. A change in baseline composition of LDL particles from large to medium and small LDL particles was associated with an increased cardiovascular risk, especially for CHD.

Risk factors associated with retinal vein occlusion.

AIMS: Retinal vein occlusion (RVO) is the most frequent retinal vascular disease after diabetic retinopathy in which arterial risk factors are much more relevant than venous factors. The objective was to evaluate the role of risk factors in the development of the first episode of RVO. SUBJECTS AND METHODS: One hundred patients with RVO [mean age 56 years, 42% females and mean body mass index (BMI) 27.5 kg/m(2)] were recruited consecutively from the outpatient clinic of a tertiary hospital in Valencia (Spain). All subjects underwent clinical assessment including anthropometric and blood pressure measurements and laboratory test including homocysteine, antiphospholipid antibodies (aPLAs) and thrombophilia studies. In half of the subjects, a carotid ultrasonography was performed. Three control populations matched by age, sex and BMI from different population-based studies were used to compare the levels and prevalence of arterial risk factors. One cohort of young patients with venous thromboembolic disease was used to compare the venous risk factors. RESULTS: Blood pressure levels and the prevalence of hypertension were significantly higher in the RVO population when compared with those for the general populations. There was also a large proportion of undiagnosed hypertension within the RVO group. Moreover, carotid evaluation revealed that a large proportion of patients with RVO had evidence of subclinical organ damage. In addition, homocysteine levels and prevalence of aPLAs were similar to the results obtained in our cohort of venous thromboembolic disease. CONCLUSIONS: The results indicate that hypertension is the key factor in the development of RVO, and that RVO can be the first manifestation of an undiagnosed hypertension. Furthermore, the majority of these patients had evidence of atherosclerotic disease. Among the venous factors, a thrombophilia study does not seem to be useful and only the prevalence of hyperhomocysteinaemia and aPLAs is higher than in the general population.

Enfermedad pulmonar obstructiva crónica. ¿Los tiempos están cambiando? / Chronic obstructive pulmonary disease. Are the times changing?

La enfermedad pulmonar obstructiva crónica (EPOC) es una de las afecciones más prevalentes, y que provoca mayor morbimortalidad en nuestro país. En la actualidad la EPOC se considera una afección tratable, de origen inflamatorio y frecuentemente asociada a otras enfermedades, cuya prevalencia está claramente aumentada en los pacientes con EPOC, independientemente de otras variables de confusión como el tabaquismo. Los tratamientos actuales han demostrado frenar la pérdida de función pulmonar, disminuir el número de exacerbaciones, mejorar la calidad de vida relacionada con la salud y prolongar la supervivencia. La recuperación de los fenotipos clásicos y de otros nuevos como el de los pacientes con exacerbaciones frecuentes o el de EPOC con comorbilidad asociada, deberían permitirnos individualizar los tratamientos, al mismo tiempo que los avances en investigación genética y de los mecanismos inflamatorios nos permitirán conocer mejor la enfermedad y añadir nuevas terapias a las ya existentes(AU)

Chronic obstructive pulmonary disease (COPD) is one of the most prevalent diseases and a major cause of morbidity and mortality in Spain. Currently, COPD is considered a treatable disease with an inflammatory origin that is frequently associated with other diseases. The prevalence of comorbidity is clearly increased in patients with COPD, irrespective of other confounding variables such as smoking. Current treatments have been proven to slow the loss of lung function, decrease the number of exacerbations and improve health-related quality of life and survival. New advances regarding the classics and more recent phenotypes such as patients with frequent exacerbations or COPD with associated comorbidity should allow for more individualized treatment while advances in genetic research and inflammatory mechanisms of the disease will help us to increase our knowledge of the disease and the development of new treatments(AU)

[Complexity in chronic obstructive pulmonary disease. Individualized treatment, new approaches, phenotypes and comorbidities]. / Complejidad de la EPOC. Tratamiento individualizado, nuevas aproximaciones, fenotipos, comorbilidades.

The current definition and severity stages of chronic obstructive pulmonary disease (COPD) focus excessively on spirometric criteria alone. Measurement of chronic airflow obstruction and its degree of reversibility is complex. The etiology of this disease cannot be fully explained in relation to smoking and the heterogeneity of this systemic disease that affects mainly the lung cannot be expressed through forced expiratory volume in 1 second (FEV(1)) alone. This simplification was useful for a period but the loss of clinical subtlety in large studies hampers interpretation of their results and their conclusions lose external validity. Accepting the complexity of COPD requires substituting the analytic focus centered on FEV(1) for a multifaceted approach that integrates other aspects in the analysis of real COPD patients. Identifying and classifying clinically significant subgroups or "COPD phenotypes" may help to guide treatment more efficiently. In patients with COPD, mortality due to cardiovascular diseases or malignancies occurs earlier than that due to respiratory causes; that is, deaths from COPD occur in patients not succumbing to cardiovascular diseases or cancer. To prolong survival in these patients, comorbidity should be evaluated and treated. COPD treatment based on severity measured by lung function can no longer be recommended. The various therapeutic options should be individualized according to the patient's other characteristics.

Conducta a seguir ante la EPOC desde Medicina Interna / Approach to COPD management in Internal Medicine

Un paciente de 60 años, con obesidad y diabetes mellitus tipo 2, consulta por presentar hipertensión arterial, temeroso de padecer una cardiopatía isquémica. También presenta antecedentes de tabaquismo de 20 cigarrillos/día desde hace 30 años, pero eso no le preocupa. En el interrogatorio refiere, sin darle importancia, y desde hace años tos y disnea de medianos esfuerzos. Muy probablemente ningún internista dude sobre si debemos evaluar y tratar su diabetes mellitus tipo 2 o su hipertensión arterial, estimar su riesgo cardiovascular o si padece un síndrome metabólico, intentar reducir su obesidad y que abandone el tabaquismo; pero ¿le etiquetaríamos de bronquitis crónica o de EPOC?, ¿debemos hacerle una espirometría y un test broncodilatador?, ¿tratar su probable EPOC? Todos sus síntomas actuales probablemente se deban solo a la EPOC(AU)

A 60-year old male patient with obesity and type 2 diabetes mellitus consulted due to high blood pressure, fearful of suffering ischemic heart disease. He also had a background of smoking 20 cigarettes/day for the last 30 years, but this did not concern him. In the questioning, he reported, although he did not consider it important, that he had cough and dyspnea on moderate exertions for some years. It is very unlikely that any internal medicine physician would doubt about whether to evaluate and treat his type 2 diabetes mellitus or high blood pressure, calculate his cardiovascular risk or if he has a metabolic syndrome, attempt to reduce his obesity and to make him stop smoking. However, should we label him as having chronic bronchitis or COPD? Should we perform a spirometry and bronchodilater test, treat his probable COPD? All his current symptoms are probably only due to COPD(AU)

[Type 2 diabetes mellitus and health-related quality of life: results from the Hortega Study]. / Diabetes mellitus tipo 2 y calidad de vida relacionada con la salud: resultados del Estudio Hortega.

OBJECTIVE: To evaluate which health-related quality of life (HRQOL) aspects are affected by type 2 diabetes mellitus (DM) and influence of glycemic control and associated cardiovascular risk factors (CVRF). METHOD: A descriptive cross-sectional study was carried out in the health coverage area of our hospital. Following a multiphase sampling a final sample of 495 people, representative of the general population, was analyzed. HRQOL was evaluated with the Short-Form 36 (SF-36). RESULTS: After adjustment for sociodemographic variables (age, sex, education level, marital status, number of persons residing together, labor situation, social class and rural or urban ambience), comorbidity and CVRF (smoking, systolic blood pressure, LDL-cholesterol level and body mass index), the patients with DM presented lower scores on four SF-36 scales: physical function, bodily pain, general health and vitality. Among people with diabetes systolic blood pressure, body mass index and glycosylated hemoglobin, but not lipid levels, were negatively correlated to some SF-36 scores. CONCLUSIONS: In our population patients with DM present a poorer HRQOL, specifically in the physical dimensions, but neither their social function nor their mental health was affected. Hypertension, obesity and poor glycemic control are associated with worst subjective state of health.

Diabetes mellitus tipo 2 y calidad de vida relacionada con la salud: resultados del Estudio Hortega / Type 2 diabetes mellitus and health-related quality of life: results from the Hortega Study

Objetivo: Evaluar qué aspectos de la calidad de vida relacionada con la salud (CVRS) se ven afectados por la diabetes mellitus tipo 2 (DM), y la influencia del control glucémico y de los factores de riesgo cardiovascular (FRCV) asociados. Método: Llevamos a cabo un estudio transversal descriptivo en el área sanitaria de nuestro hospital. Tras un muestreo polietápico analizamos una muestra final de 495 personas, representativa de la población general. La CVRS se valoró con el Short-Form 36 (SF-36). Resultados: Tras ajustar por variables sociodemográficas (edad, sexo, nivel de estudios, estado civil, número de persones residiendo juntas, situación laboral, clase social y medio rural o urbano), comorbilidad y FRCV (tabaquismo, tensión arterial sistólica, LDL-colesterol e índice de masa corporal), los pacientes con DM presentaban menores puntuaciones en cuatro escalas del SF-36: función física, dolor corporal, salud general y vitalidad. Entre los diabéticos tensión arterial sistólica, índice de masa corporal y hemoglobina glicosilada se correlacionaban negativamente con algunas escalas, pero no así los niveles lipídicos. Conclusiones: En nuestra población los pacientes con DM presentan una peor CVRS específicamente en las dimensiones físicas, sin que se vean afectadas ni su función social ni su salud mental. Hipertensión, obesidad y mal control glucémico se asocian en estos enfermos a un peor estado subjetivo de salud

[Prevalence of mild to moderate chronic kidney disease in the general population of Spain. Hortega study]. / Prevalencia de la enfermedad renal crónica leve y moderada en población general. Estudio Hortega.

BACKGROUND: Although the epidemiology of subjects with end-stage renal disease is well-known in Spain, the prevalence of mild to moderate chronic kidney disease (CKD) in the general population is unknown. In order to measure this, it is necessary to carry out studies in the general population including those who are not health service patients. During epidemiology studies, the method of measuring glomerular filtration rate can change significantly the measurements of the prevalence of mild to moderate CKD. METHODS: Between 1997 and 2000, we performed a multi-phase descriptive polistratified epidemiological transversal study. The section of public chosen was between the ages of 15 and 85 living in the health area of western Valladolid (Spain). We calculated creatinine clearance using four methods: serum creatinine concentration, creatinine clearance using 24-hour urine samples adjusting the volume to the expected creatinuria with the Walser formulas, using the Cockcroft-Gault (CG) equation and applying the Modification of Diet in Renal Disease (MDRD) study abbreviated formula. We classified the level of kidney function, according to the National Kidney Foundation-Dialysis Outcomes Initiative (NFK-DOQI) guidelines. RESULTS: The instances of stages 2 and 3 CKD rise with age and are more common in women than men. This tendency is apparent in middle age and persons of 65 and above. Using the CG method, almost half the old women had a stage 3 CKD as opposed to a third of the men. If the measurement is performed using the abbreviated MDRD study, there are very few differences between the sexes. The prevalence of stage 3 CKD is similar (around 8%) but the prevalence of stage 2 CKD rises to 60% as opposed to 36% calculated using the CG equation. After comparing the results obtained with those of the third National Health and Nutrition Examination Survey Study (see table VII), the measurements of stage 3 CKD using the CG formula or by means of expected creatininuria coincide relatively, although the prevalence of stage 2 CKD is higher in persons of 65 and over. If we use the abreviated MDRD study, the prevalences increase by more than 20%. CONCLUSIONS: The prevalence of stages 2 and 3 CKD is clearly influenced by the method of calculation used. The prevalence of stage 2 CKD affects at least a third of the general population while those affected by stage 3 CKD are between 3.3% and 8.5%.

Effects of dietary intake and life style on bone density in patients with diabetes mellitus type 2.

OBJECTIVE: The aim of our study was to investigate the relation among glycemic control, lifestyle and dietary intake with bone mineral density in patients with diabetes mellitus type 2. DESIGN: Cross-sectional study. SETTING: Tertiary care hospital. PARTICIPANTS: A cross-sectional study in a tertiary care hospital was performed. Ninety-two patients attending our diabetes service (56 females/36 males) with diabetes mellitus type 2 were enrolled in a consecutive way. The inclusion criteria were diabetes diagnosed >40 years of age, with type 2 diabetes defined in accordance with the criteria of the American Diabetes Association and no use of dietary supplements. Body mass index, waist-to-hip ratio, glucose level, and HbA1c levels were assessed in all patients. X-ray densitometry of the calcaneal region and a 3-days written food record keeping, and a qualitative questionnaire of lifestyle were also performed. RESULTS: A total of 21.7% of patients had osteoporosis (T score <2.5 SD). Patients were overweight with a high BMI and a medium glucose control. Patients with osteoporosis were older than those without osteoporosis (67.8 +/- 6.9 vs. 62.1 +/- 9.2 years; p < 0.05). Significant differences were detected between patients without and with osteoporosis in calcium intake (1,219.37 +/- 387 vs. 839 +/- 251 mg/day; p < 0.05) and zinc intake (9.23 +/- 3.5 vs. 13.3 +/- 6.9 mg/day; p < 0.05), respectively. No differences were detected in other dietary dairy intakes. In correlation analysis age (r = -0.23; p < 0.05) and BMI (r = 0.48; p < 0.05) was correlated with BMD. In univariate analysis with dicotomic variables, only exercise was positive associated with osteoporotic status (87.5% exercise habit in patients without osteoporosis and 25% exercise habit in patients with osteoporosis; p < 0.05). In a logistic model with the dependent variable (osteoporosis), remained in the final model dietary dairy intake of calcium and zinc, BMI, age and exercise. Exercise, calcium intake and BMI were protective factors. Zinc intake, and age were risk factors. CONCLUSIONS: Exercise, calcium intake, body mass index had a protective role in bone mineral density in patients with diabetes mellitus type 2. Zinc intake and age were risk factors in our population.

[Cardiovascular risk factors in diabetic patients. Cross-sectional study in general population: Hortega study]. / Factores de riesgo cardiovascular en pacientes diabéticos. Estudio epidemiológico transversal en población general: estudio Hortega.

OBJECTIVE: To find in our population with diabetes mellitus (DM) the prevalence of other cardiovascular risk factors, as well as their degree of control. METHOD: A cross-sectional study was carried out in 15-82 years population of our health coverage area, by means of a mailed survey sent to a simple random sample composed of 33,022 individuals, and a interview with collection of exploration and analitic data to a 495 people sub-sample. RESULTS: Among patients with DM 47/ have history of hypertension, and 58/ blood pressure =140/90 mmHg. Only 33/ have values <130/85 mmHg, and the percentage of patients with controlled blood pressure is significantly inferior between the women. There is history of hipercholesterolaemia in 45 210 / of diabetic patients versus 19/ of non-diabetic population; in the former group the total and LDL cholesterol levels are significantly lower. Smoking affects equally to both groups, while obesity and central obesity are more frequent between diabetic patients, although only in the case of women. CONCLUSIONS: In our diabetic population blood pressure control is limited: two third parts of the patients show values above recommended. This fact forms a contrast with a high degree of dyslipidemia control. We should pay a greater attention to hypertension treatment in patients with diabetes, mainly in women, and promote smoking cessation interventions essentially in males.

Factores de riesgo cardiovascular en pacientes diabéticos. Estudio epidemiológico transversal en población general: estudio Hortega / Cardiovascular risk factors in diabetic patients. Cross-sectional study in general population: Hortega study

Objetivo: Conocer en nuestra población con diabetes mellitus (DM) la prevalencia de otros factores de riesgo cardiovascular, así como su grado de control. Método: Estudio epidemiológico transversal llevado a cabo en la población de 15-82 años de nuestro área sanitaria, mediante una encuesta por correo enviada a una muestra aleatoria simple formada por 33.022 sujetos, y una entrevista con recogida de datos de exploración y analíticos a una submuestra de 495 individuos. Resultados: Un 47 por ciento de los pacientes con DM tiene antecedentes de hipertensión, y se detecta una tensión arterial 140/90 mmHg en el 58 por ciento. Tan sólo un 33 por ciento presenta valores <130/85 mmHg, con un porcentaje de enfermos con cifras de TA controladas significativamente inferior entre las mujeres. El 45 por ciento de los diabéticos tiene antecedentes de hipercolesterolemia, frente a un 19 por ciento de la población no diabética, presentando los primeros cifras significativamente más bajas de colesterol total y LDL. El tabaquismo afecta por igual a ambos grupos, mientras que la obesidad y la obesidad central son más frecuentes entre los diabéticos, aunque solamente en el caso de las mujeres. Conclusiones: El control tensional en nuestra población diabética es escaso: dos terceras partes de los pacientes mantienen cifras tensionales por encima de las recomendadas; este hecho contrasta con un alto grado de control de la dislipemia. Debemos prestar una mayor atención al tratamiento de la hipertensión de los pacientes con DM, sobre todo en las mujeres, y avanzar en las estrategias de lucha antitabáquica fundamentalmente en los varones (AU)

Prevalencia, grado de detección, tratamiento y control de la hipertensión arterialen población general. Estudio Hortega / Prevalence, degree of detection, treatment and control of arterial hypertension in the general population. Hortega study

Pocos estudios analizan la epidemiología de la hipertensión arterial (HTA) en población general de 15 a 85 años aplicando los criterios actuales. Sujetos y método. Realizamos un estudio epidemiológico transversal en etapas sucesivas sobre población general de Valladolid (España). En una primera etapa destinada a garantizar la representatividad de muestras menores tomadas al azar, realizamos una encuesta por correo breve sobre una muestra aleatoria de 34.742 personas. En una segunda etapa estudiamos una muestra estratificada de 1.500 individuos mediante una encuesta por correo extensa, y de ellas seleccionamos a un tercio al azar y les hicimos además entrevista en consulta con toma de la presión arterial (PA) mediante un esfigmomanómetro automático Omron-711 validado. Resultados. La prevalencia de HTA (PA 140/90 mmHg) fue del 32 por ciento en la población general y alcanzó el 77 por ciento entre los mayores de 65 años. La prevalencia fue mayor en mujeres y únicamente el 44 por ciento del total de los sujetos se reconocía hipertenso. La prevalencia de HTA sistólica aislada (PAS 140 mmHg y PAD < 90 mmHg) en la muestra de población general fue del 14 por ciento, más común en mujeres a cualquier edad, la de diastólica aislada (PAD 90 mmHg y PAS<140 mmHg) del 5 por ciento y la hipertensión de pulso (PP 65 mmHg ) del 14 por ciento. La prevalencia efectiva de HTA (población con PA 140/90 mmHg tratada o no tratada) fue del 24,7 por ciento. El 71 por ciento de los hipertensos conocidos (14 por ciento del total de hipertensos) estaba en tratamiento antihipertensivo farmacológico, aunque únicamente el 23 por ciento estaba controlado con cifras inferiores a 140/90 mmHg (7,8 por ciento del total de hipertensos).Conclusión. La HTA afecta a un tercio de nuestra población, aunque menos de la mitad son conscientes de ello. Uno de cada 4 adultos padece una HTA sin control efectivo. El grado de control en población general es malo, aunque con una leve tendencia a mejorar y similar al detectado en otros subgrupos de población. Es necesario mejorar la detección y la eficiencia en el control de la HTA conocida y tratada (AU)
