Estudio prospectivo de los valores de hormonas y péptidos relacionados con el metabolismo glucolipídico en pacientes obesos mórbidos sometidos a una gastrectomía vertical / Prospective study of gluco-lipidic hormone and peptide levels in morbidly obese patients after sleeve gastrectomy

INTRODUCCIÓN: Diferentes hormonas y péptidos implicados en el apetito y el metabolismo lipídico e hidrocarbonado se han estudiado en relación con la obesidad mórbida y su variación tras cirugía bariátrica. El objetivo de nuestro trabajo es evaluar las variaciones de diferentes moléculas relacionadas con el metabolismo glucolipídico durante el primer año tras una gastrectomía vertical en pacientes obesos mórbidos. MATERIAL Y MÉTODO: Estudio prospectivo en pacientes operados mediante gastrectomía vertical entre noviembre de 2009 y enero de 2011. Se determinaron y analizaron las variaciones en diferentes parámetros clínicos, antropométricos y analíticos relacionados con el metabolismo glucolipídico en todos los pacientes en el preoperatorio, al primer y quinto días, al mes, a los 6 meses y al año postoperatorio, realizando el estudio estadístico con ayuda del programa SPSS 20.0. RESULTADOS: De los 20 pacientes estudiados, el 60% eran mujeres con una mediana de edad de 45 años. La mediana del índice de masa corporal (IMC) preoperatorio fue de 48,5 kg/m2 y el 70% padecían síndrome de apnea obstructiva del sueño (SAOS), el 65% hipertensión arterial (HTA), el 45% dislipidemia y el 40% diabetes mellitus. Al año de la cirugía, el porcentaje de exceso de IMC perdido fue del 72% y la tasa de curación o mejoría de la dislipidemia fue del 100%, de diabetes el 87,5%, de HTA el 84,6% y de SAOS el 57,1%. En ese período los niveles de glucemia en ayunas disminuyeron de forma significativa (p < 0,001), mostrando los niveles de IGF-1 y colesterol HDL un aumento significativo. Los niveles de adiponectina aumentaron y los de leptina (p = 0,003), insulina (p = 0,004) y triglicéridos (p = 0,016) disminuyeron de forma significativa al año de la intervención. Los valores de ACTH (que disminuyeron durante los 6 primeros meses), hemoglobina glucosilada, colesterol total y LDL no experimentaron cambios significativos al año de la intervención. CONCLUSIÓN: La gastrectomía vertical es una técnica que presenta buenos resultados ponderales y de curación de comorbilidades, produciendo modificaciones significativas durante el primer año postoperatorio en los niveles sanguíneos de diferentes parámetros relacionados con el metabolismo glucolipídico como la glucosa, IGF-1, insulina, leptina, triglicéridos y colesterol HDL

INTRODUCTION: Different hormones and peptides involved in lipid and carbohydrate metabolism have been studied in relation to morbid obesity and its variation after bariatric surgery. The aim of this study is toevaluate variations in different molecules related to glico-lipidic metabolism during the first year after sleeve gastrectomy in morbidly obese patients. MATERIAL AND METHODS: Prospective study in patients undergoing sleeve gastrectomy between November 2009 and January 2011. We analyzed changes in different clinical, anthropometric and analytic parameters related with glico-lipidic metabolism in all patients in the preoperative period, first postoperative day, fifth day, one month, 6 months and one year after surgery. Statistical analysis was performed using SPSS 20.0. RESULTS: We included 20 patients, 60% were women with a median of age of 45 years. Median of body mass index (IMC) was 48,5 kg/m2 and 70% had obstructive sleep apnea syndrome (SAOS), 65% arterial hypertension (HTA), 45% dyslipidemia and 40% diabetes mellitus. One year after surgery, the percentage of excess of BMI loss was 72% and the rate of cure or improvement of dyslipidemia was 100%, diabetes 87,5%, HTA 84,6% and SAOS 57,1%. At this time, glycemia levels decreased significantly (P < .001), and levels of IGF-1 and HDL-cholesterol increased significantly. Levels of adiponectine increased and leptine (P = .003), insulin (P = .004) and triglycerides (P = .016) decreased significantly one year after the surgery. ACTH levels (that decreased during first 6 months after surgery), glycosilated hemoglobin, total cholesterol and LDL-cholesterol had no changes one year after surgery. CONCLUSIONS: Sleeve gastrectomy is a surgical technique with good results of weight loss and cure of comorbidities. This procedure induces significant modifications in blood levels of glico-lipidic metabolism related peptides and hormones, such as glucose, IGF-1, insulin, leptin, triglycerides and HDL-cholesterol

A prospective study on inflammatory parameters in obese patients after sleeve gastrectomy.

Different hormones and peptides involved in inflammation have been studied in and related to obesity. The aim of our work is to assess the variations of different molecules related to inflammation in obese patients during the first year following sleeve gastrectomy. This was a prospective study on patients who underwent sleeve gastrectomy. The variations in different clinical, anthropometric, and analytical parameters related to inflammation were determined and analysed in all patients at the preoperative visit and at the first and fifth days, first and sixth months, and 1 year following surgery. We enrolled 20 patients to the study. The median body mass index (BMI) before intervention was 48.5 kg/m2. With respect to comorbidities, 70% of the patients had obstructive sleep apnoea syndrome (OSA), 65% high blood pressure, 45% dyslipidaemia, and 40% diabetes mellitus (DM). The median percentage of BMI lost (%BMIL) 1 year after the intervention was 71%. The dyslipidaemia healing or improvement rate was 100%, whereas it was 87.5% for diabetes, 84.6% for hypertension, and 57.1% for OSA. During the 1-year postintervention period, the average levels of adiponectin increased, although not significantly, whereas those of leptin significantly decreased. In addition, the blood levels of MCP-1, IL-6, CRP, ferritin, and PAI-1 significantly decreased in that period. Sleeve gastrectomy is a surgical technique that is associated with improvements in body weight and comorbid conditions from the first postoperative months, which lead to significant variations in the levels of different inflammation-related parameters and a decrease in the levels of leptin, IL-6, CRP, MCP-1, ferritin, and serpin (PAI-1).

Regional variations in test requiring patterns of general practitioners in Spain.

OBJECTIVE: To analyze the requesting patterns for a range of laboratory tests ordered in 2009 from eight laboratories providing services to eight health areas, using appropriate indicators. DESIGN: Indicators measured every test request per 1,000 inhabitants, and indicators that measured the number of tests per related test requested by general practitioners were calculated. The savings generated, if each Health Care Department achieved the appropriate indicator standard, were also calculated. Laboratory Information System registers were collected, and indicators were calculated automatically in each laboratory using a data warehouse application. RESULTS: There was a large difference in demand for tests by health areas. The ratio of related tests also showed a great variability. The savings generated if each Health Care Department had achieved the appropriate indicator standard were €172,116 for free thyroxine, €18,289 for aspartate aminotransferase, and €62,678 for urea. CONCLUSIONS: Considerable variability exists in general practitioners' demand for laboratory tests.

Evaluation of PSA testing by general practitioners: regional study in the autonomic Community of Valencia.

OBJECTIVES: The aim of the study is to compare the use of PSA testing among general practitioners (GPs). METHODS: The number of PSA tests ordered by general practitioners in the years 2008-2009 was examined in a cross-sectional study of nine health districts of Spain. The percentage of PSA ordered to men younger than 50 (PSA<50/PSAtotal) and 40 years (PSA<40/PSAtotal) was calculated. The percentage of men over 50 years who were attended was also calculated and this data was compared with the number of PSA ordered to this population. For two of the departments, these data were also compared between GPs and urologists. RESULTS: PSA testing in 2009 is higher than 2008 in seven health districts. PSA testing in men younger than 50 years was increased along the period of the study and in men younger than 40 years remained steady. The differences between the values of the indicators for urologists and GPs are significant. CONCLUSIONS: The number of PSA tests and the percentage performed to men younger 50 years has been increasing and the variability is high. These data are suggestive for interventions focused on PSA testing and prostate cancer screening in primary care settings.

Evaluación de la solicitud de antígeno prostático específico por atención primaria: estudio piloto regional en la comunidad valenciana / Evaluation of psa testing by general practitioners: regional study in the autonomic community of valencia

OBJETIVO: El objetivo del estudio es la valoración del patrón de solicitud de PSA por los médicos de Atención Primaria (AP).MÉTODOS: Estudio transversal de la solicitud de PSA por médicos de AP en nueve Departamentos de Salud. Se evaluó el número de solicitudes de PSA y el porcentaje de PSA solicitados a menores de 50 años (PSA<50/PSAtotal) y también a menores de 40 años respecto del total de PSA solicitados (PSA<40/PSAtotal).También se calculó el porcentaje de varones mayores de 50 años atendidos y se comparó con el número de PSA solicitados a esa población. Para dos de los Departamentos, también se compararon estos datos con los mismos para médicos especialistas en Urología.RESULTADOS: En siete de los Departamentos la demanda en 2009 es superior a la del año 2008. La demanda a varones menores de 40 años se mantiene estable y a varones menores de 50 años aumenta progresivamente a lo largo del periodo del estudio. Las diferencias entre los valores de los indicadores para urólogos y médicos de AP son significativas.CONCLUSIONES: El número de solicitudes de PSA y el porcentaje realizado a varones menores de 50 años ha ido incrementándose y la variabilidad en la solicitud es elevada, lo que indica la necesidad de establecer estrategias orientadas a la adecuación de la demanda mediante la comunicación entre profesionales(AU)

Evaluación del patrón de solicitud de hemoglobina glucosilada por Atención Primaria: estudio piloto regional en la Comunidad Valenciana / An evaluation of glycosylated hemoglobin requesting patterns in a primary care setting: a pilot experience in the Valencian Community (Spain)

Objetivo Mostrar el patrón de solicitud de hemoglobina glucosilada (HbA1c) en ocho departamentos de salud mediante el cálculo de indicadores de adecuación de la demanda. Métodos Estudio transversal en el que se recogen el número de HbA1c solicitadas desde Atención Primaria durante los años 2008 y 2009. Como indicador de adecuación se calculó el porcentaje de valores de HbA1c con resultado inferior a 6,5%. Las variables y los indicadores se recogieron y calcularon de forma automatizada. También se calculó en cada departamento de salud el número de determinaciones de HbA1c teóricas que deberían haber sido solicitadas según datos de prevalencia conocida. Resultados se observó un incremento progresivo de la demanda de determinaciones de HbA1c y, aproximadamente el 54% de los valores de HbA1c en siete de estos ocho departamentos fueron inferiores a 6,5%. El número de HbA1c teóricas que deberían haber sido solicitadas según la prevalencia de diabetes fue mayor que el número solicitado en todos los departamentos. Conclusión Los resultados parecen indicar la inadecuación en la solicitud de la HbA1c en los departamentos de salud estudiados, no sólo por la probable sobreutilización en pacientes no diabéticos sino por la infrautilización en pacientes que sí lo son (AU)

Objective To assess the pattern of glycosylated hemoglobin (HbA1c) requests by clinicians from eight health departments by calculating indicators of demand appropriateness. Methods A cross-sectional study of the number of HbA1c requests by primary care clinics in 2008 and 2009. The indicator of demand appropriateness was the proportion of HbA1c values lower than 6.5%. Variables were collected and indicators were automatically calculated. The number of HbA1c measurements that should theoretically have been requested according to known diabetes prevalence data was also calculated. Results A progressive increase was seen in demand for HbA1c measurements. Approximately 54% of HbA1c values obtained in seven of the eight departments studied were lower than 6.5%. The number of theoretical HbA1c requests that would have been expected based on the known prevalence of diabetes was higher than the number of HbA1c requests in all departments. Conclusion The results appear to suggest that HbA1c requests by the health departments studied were not always appropriate. HbA1c measurements were probably overused in patients without diabetes and underused in patients with diabetes (AU)
