Cambios en la prevalencia del tabaquismo en los adolescentes en España

ResumenObjetivoAnalizar la información sobre consumo de tabaco en adolescentes a partir de diversas encuestas escolares.DiseñoSe extraen de diversos estudios los datos relativos a prevalencia de fumadores diarios al final de la escuela secundaria obligatoria por sexo, analizando tendencias.EmplazamientoSe revisan los 5 estudios representativos de adolescentes en España: Encuesta Estatal sobre Uso de Drogas en Estudiantes de Secundaria (ESTUDES); Estudio de Comportamientos de los Escolares Relacionados con la Salud (ECERS-HBSC); Sistema de Vigilancia de Factores de Riesgo asociados a Enfermedades No Transmisibles dirigido a población Juvenil (SIVFRENT-J); estudio de Factores de Riesgo en Estudiantes de Secundaria (FRESC); Estudio de Monitorización de las Conductas de Salud de los Adolescentes (EMCSAT).ResultadosLa prevalencia de fumadores diarios varía entre estudios, en varones entre 8,5 y 13,3% y en chicas entre 12,7 y 16,4%. Aunque se aprecian oscilaciones en algunos estudios, la tendencia entre 1993 y 2008 es de descenso. Con los datos más recientes se puede estimar un declive anual ponderado de la prevalencia de tabaquismo en la adolescencia del 6,47% anual para los varones y 6,96% para las chicas.ConclusionesHay un patrón de descenso de la prevalencia de fumadores diarios adolescentes en España a partir de los diversos estudios existentes, que ofrecen datos consistentes, aunque hay que mantener la vigilancia debido a la existencia de oscilaciones. Esto concuerda con la información derivada de las ventas y de encuestas en población adulta. En cualquier caso, sería deseable que el ritmo de cambio fuera más acentuado y constante.AbstractObjectiveTo analyse information on adolescent use of tobacco in Spain from different school surveys.DesignData on daily smoking prevalence by sex at the end of compulsory education is extracted and figures are compared, analysing trends.SettingThe five representative studies on adolescents in Spain are reviewed: The National Survey on Drug Use in Secondary School Children (Encuesta estatal sobre uso de drogas en estudiantes de secundaria (ESTUDES); Survey of Health Behaviour in School-aged Children (HBSC-ECERS); Surveillance System of Risk Factors Associated With Non-Transmittable diseases in the Young Population (Sistema de Vigilancia de Factores de Riesgo Asociados a Enfermedades No Transmisibles dirigido a población Juvenil)(SIVFRENT-J); Study of Risk Factors in Secondary School Children (Estudio de factores de riesgo en estudiantes de secundaria) (FRESC); Surveillance Study of Health Behaviour in Adolescents (Estudio de Monitorización de las Conductas de Salud de los Adolescentes) (EMCSAT).ResultsThe prevalence of daily smokers varies among studies, in boys from 8.5 to 13.3% and in girls from 12.7 to 16.4%. Although some series show variations, the trend from 1993 to 2008 is downwards. With data from recent years, weighted annual declines in smoking prevalence in adolescence can be estimated to be 6.47% for boys and 6.96% for girls.ConclusionsThere is a decreasing pattern in adolescent daily smoking prevalence in Spain from the different existing studies, which provide consistent data, although surveillance must be kept due to fluctuations. This is in agreement with tobacco sales statistics and health surveys in the adult population. However, the pace of change should be more rapid and constant

Trend Analysis of Bullying Victimization Prevalence in Spanish Adolescent Youth at School

This is the peer reviewed version of the following article: Inmaculada Sanchez-Queija, Irene Garcia Moya, and Carmen Moreno, ‘Trend Analysis of Bullying Victimization Prevalence in Spanish Adolescent Youth at School’, Journal of School Health, Vol. 87 (6): 457-464, June 2017, which has been published in final form at https://doi.org/10.1111/josh.12513. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving.BACKGROUND We analyze trends in bullying victimization prevalence in a representative sample of Spanish adolescent schoolchildren in 2006, 2010, and 2014. METHODS We distinguish between reported bullying, which is assessed via the global question in the Revised Bully/Victim Questionnaire by Olweus, and observed bullying, which is a measure developed from the answers that the adolescents gave to specific items that refer to different types of bullying that have been codified as physical, verbal, and relational bullying. RESULTS For 2006 and 2010/2014, the results show stability in the assessment of reported bullying and an increase in observed bullying, analyzed both globally and within the 3 categories: physical, verbal, and relational. CONCLUSIONS A valid, reliable, and accurate measure to detect cases of bullying is necessary, as is the importance of continuing efforts devoted to raising awareness and the prevention of this phenomenon.Peer reviewedFinal Accepted Versio

Morphofunctional and Molecular Assessment of Nutritional Status in Head and Neck Cancer Patients Undergoing Systemic Treatment: Role of Inflammasome in Clinical Nutrition

Malnutrition in patients with head and neck cancer is frequent, multifactorial and widely associated with clinical evolution and prognosis. Accurate nutritional assessments allow for early identification of patients at risk of malnutrition in order to start nutritional support and prevent sarcopenia. We aimed to perform a novel morphofunctional nutritional evaluation and explore changes in inflammasome-machinery components in 45 patients with head and neck cancer who are undergoing systemic treatment. To this aim, an epidemiological/clinical/anthropometric/biochemical evaluation was performed. Serum RCP, IL6 and molecular expression of inflammasome-components and inflammatory-associated factors (NOD-like-receptors, inflammasome-activation-components, cytokines and inflammation/apoptosis-related components, cell-cycle and DNA-damage regulators) were evaluated in peripheral-blood mononuclear-cells (PBMCs). Clinical-molecular correlations/associations were analyzed. Coherent and complementary information was obtained in the morphofunctional nutritional assessment of the patients when bioimpedance, anthropometric and ultrasound data were analyzed. These factors were also correlated with different biochemical and molecular parameters, revealing the complementary aspect of the whole evaluation. Serum reactive C protein (RCP) and IL6 were the most reliable parameters for determining patients with decreased standardized phase angle, which is associated with increased mortality in patients with solid malignancies. Several inflammasome-components were dysregulated in patients with malnutrition, decreased phase angle and dependency grade or increased circulating inflammation markers. A molecular fingerprint based on gene-expression of certain inflammasome factors (p27/CCL2/ASC) in PBMCs accurately differentiated patients with and without malnutrition. In conclusion, malnutrition induces a profound alteration in the gene-expression pattern of inflammasome-machinery components in PBMCs. A comprehensive nutritional assessment including novel morphofunctional techniques and molecular markers allows a broad characterization of the nutritional status in cancer patients. Profile of certain inflammasome-components should be further studied as potential targets for nutrition-focused treatment strategies in cancer patients

Weight-related quality of life in spanish obese subjects suitable for bariatric surgery is lower than in their North American counterparts: a case–control study

Multicenter study[Abstract] Background: Obesity impairs quality of life, but the perception of the impairment could be different from one country to another. The purpose was to compare weight-related quality of life (QOL) between cohorts from Spain and North America. Methods: A cross-sectional case-control study was performed between two populations. Four hundred Spanish and 400 North American obese subjects suitable for bariatric surgery closely matched for race, gender, age, and body mass index (BMI) were included. Two non-obese control groups matched for gender, age, and BMI from each population were also evaluated (n = 400 in each group). The participants completed the Impact of Weight on Quality of Life-Lite (IWQOL-Lite) questionnaire, a measure of weight-related QOL. Results: Spanish morbidly obese patients showed poorer QOL than their North American counterparts in physical function, sexual life, work, and total score. By contrast, Spanish non-obese control subjects reported better QOL in all domains than their North American counterparts. Women, both in Spain and North America, reported reduced QOL compared to men on the domain of self-esteem. In addition, North American women reported reduced QOL on the sexual life domain compared to men. BMI correlated negatively with all domains of QOL except for self-esteem in both national groups. Conclusions: Spanish obese subjects suitable for bariatric surgery report poorer weight-related quality of life than their North American counterparts, and obese women, regardless of nationality, perceive a reduced quality of life compared to men

Hepatic galectin-3 is associated with lipid droplet area in non-alcoholic steatohepatitis in a new swine model

Non-alcoholic fatty liver disease (NAFLD) is currently a growing epidemic disease that can lead to cirrhosis and hepatic cancer when it evolves into non-alcoholic steatohepatitis (NASH), a gap not well understood. To characterize this disease, pigs, considered to be one of the most similar to human experimental animal models, were used. To date, all swine-based settings have been carried out using rare predisposed breeds or long-term experiments. Herein, we fully describe a new experimental swine model for initial and reversible NASH using cross-bred animals fed on a high saturated fat, fructose, cholesterol, cholate, choline and methionine-deficient diet. To gain insight into the hepatic transcriptome that undergoes steatosis and steatohepatitis, we used RNA sequencing. This process significantly up-regulated 976 and down-regulated 209 genes mainly involved in cellular processes. Gene expression changes of 22 selected transcripts were verified by RT-qPCR. Lipid droplet area was positively associated with CD68, GPNMB, LGALS3, SLC51B and SPP1, and negatively with SQLE expressions. When these genes were tested in a second experiment of NASH reversion, LGALS3, SLC51B and SPP1 significantly decreased their expression. However, only LGALS3 was associated with lipid droplet areas. Our results suggest a role for LGALS3 in the transition of NAFLD to NASH

Objetivo: Describir las características de la Nutrición Enteral Domiciliaria (NED) en España, registrada por el grupo NADYA-SENPE durante el año 2009. Material y métodos: Recopilación y análisis descriptivo de los datos del registro de NED del grupo NADYASENPE desde el 1 de enero al 31 de diciembre de 2009. Resultados: Se registraron 6.540 pacientes, 5,11% más que en el año anterior y 6.649 episodios de NED (3.135 en mujeres, 47,93%) pertenecientes a 32 centros hospitalarios. Siendo 6.238 (95,38%) mayores de 14 años. La edad media en los menores de 14 años fue de 3,67 ± 2,86 y de 72,10 ± 16,89 en los mayores de 14 años. La enfermedad de base que se registró con más frecuencia fue la neurológica en 2.732 (41,77%) ocasiones, seguida de la neoplasia en 1838; 28,10%. La vía de acceso se registró en 1.123 (17,17%) de los episodios, siendo más frecuente la administración por sonda nasogástrica 562 (50,04%). El tiempo medio de tratamiento nutricional fue de 323 días (10,77 meses). Finalizaron 606 episodios de NED, siendo el motivo más frecuentes el fallecimiento del enfermo, lo que aconteció en 295 (48,68%) ocasiones y el paso a alimentación oral en 219 (36,14%). Los pacientes mantenían una actividad normal en 2162 episodios de NED (32,55%) y en 2468 (37,13%) hacían vida “cama-sillón”. El grado de dependencia fue “total” en 2598 (39,07%) de los episodios registrado. El suministro de la fórmula nutricional se realizó desde el hospital en 4.183 (62,91%) casos y por la farmacia de referencia en 2.262 (el 34,02%) y el material fungible se suministró desde el hospital en 3.531 (53,11%) de los casos. Conclusiones: El número de pacientes con NED registrados es superior al del año 2008, continuando con el incremento progresivo desde el inicio del registro. Las características de los mismos mantiene el mismo perfil que en años anteriores con pequeñas variaciones.Objective: To describe the Home Enteral Nutrition Characteristics (HEN) recorded by the group NADYASENPE during 2009. Material and methods: collection and analysis of the data voluntary recorded in the HEN registry from the NADYASENPE group from January 1st to December 31st. Results: 6.540 HEN patients were registered, 5.11% more than the previous year and 6,649 episodes (3,135 in women, 47,93%) from 32 different hospitals. 6,238 of them (95,38%) were over 14 years. The mean age of the patients under 14 yr was 3,67 ± 2,86 and it was 72,10 ± 16,89 in those over 14 yr group. The base illness registered more frequently was the neurological disorders in 2,732 (41,77%) patients, followed by cancer patients in 1,838; 28,10%. The enteral access route was registered in 1,123 (17,17%) of the episodes, being more frequent the administration by nasogastric tube 562 (50,04%). The mean length of nutritional treatment by episode was 323 days (10,77 months). 606 episodes of HEN ended, being the principal reasons for discontinuing treatment the patient death in 295 (48,68%) occasions. The transition to oral feeding occurred in 219 (36,14%) cases. Patients maintained normal activity in 2162 (32,55%) HEN episodes and 2,468 (37,13%) cases were living “bedcouch”. The level of dependence was “total” in 2,598 (39,07%) of the episodes recorded. The nutritional formula was provided by the hospital in 4,183 (62,91%) cases and by the reference pharmacy in 2,262 (el 34,02%). Consumables were provided by the hospital in 3,531 (53,11%) cases. Conclusions: The number of HEN patients recorded increased from the year 2008, continuing the gradual growth increase since the start of registration. The characteristics of the patients remain in the same profile as in previous years

Exposure to secondhand and thirdhand smoke in private vehicles: Measurements in air and dust samples

Background: This study aimed to estimate airborne nicotine concentrations and nicotine, cotinine, and tobaccospecific nitrosamines (TSNAs) in settled dust from private cars in Spain and the UK. Methods: We measured vapor-phase nicotine concentrations in a convenience sample of 45 private cars from Spain (N = 30) and the UK (N = 15) in 2017-2018. We recruited non-smoking drivers (n = 20), smoking drivers who do not smoke inside the car (n = 15), and smoking drivers who smoke inside (n = 10). Nicotine, cotinine, and three TSNAs (NNK, NNN, NNA) were also measured in settled dust in a random subsample (n = 20). We computed medians and interquartile ranges (IQR) of secondhand smoke (SHS) and thirdhand smoke (THS) compounds according to the drivers' profile. Results: 24-h samples yielded median airborne nicotine concentrations below the limit of quantification (LOQ) (IQR

Conclusiones: el número de centros y profesionales colaboradores con el registro NADYA va incrementándose. Se mantienen estables las principales indicaciones y los motivos de finalización de la NPD

Bariatric surgery: evidence-based practical recommendations

[Resumen] La obesidad mórbida es, habitualmente, refractaria a los tratamientos convencionales, por lo que la modificación de hábitos dietéticos y de actividad física y/o el uso de fármacos consiguen pérdidas de peso parciales con habitual recuperación posterior. La cirugía bariátrica constituye una opción terapéutica para los casos de obesidad con elevado índice de masa corporal (IMC) asociada a comorbilidades, con buenos resultados a corto y largo plazo. El Grupo de Trabajo sobre Obesidad de la Sociedad Española de Endocrinología y Nutrición (GOSEEN) ha elaborado un documento con recomendaciones prácticas basadas en la evidencia para el tratamiento quirúrgico de la obesidad. La revisión se estructura en 3 partes. En la primera se definen los conceptos de obesidad y comorbilidades asociadas, los tratamientos médicos y sus resultados, las indicaciones y contraindicaciones para el tratamiento quirúrgico con los criterios de selección de los pacientes, el manejo pre y perioperatorio y la valoración de grupos especiales, como adolescentes y personas de edad avanzada. En la segunda parte se describen las distintas técnicas quirúrgicas, las vías de acceso y los resultados comparativos, las complicaciones tanto a corto como a largo plazo, la repercusión de la pérdida ponderal sobre las comorbilidades y los criterios para evaluar la efectividad de la cirugía. En la tercera parte se desarrolla el seguimiento postoperatorio, el control dietético en fases tempranas y más tardías tras la cirugía, y el calendario de control médico y analítico con la suplementación de los distintos macro y micronutrientes en función de la técnica quirúrgica empleada. Se incluye un apartado final sobre gestación y cirugía bariátrica, así como tablas y gráficos complementarios al texto desarrollado. La cirugía bariátrica sigue siendo un tratamiento discutido para la obesidad, pero los resultados en la corrección del exceso ponderal con mejoría en las patologías asociadas y en la calidad de vida confirman que puede ser el tratamiento de elección en pacientes seleccionados, con la técnica quirúrgica apropiada y con un correcto control pre y postoperatorio.[Abstract] Morbid obesity is usually refractory to conventional treatments. Consequently, weight that is lost by modifying diet and exercise and/or the use of drugs is usually later regained. Bariatric surgery constitutes a therapeutic option in obese patients with a high body mass index associated with comorbidities and achieves good results in both the short and the long term. The Obesity Working Group of the Spanish Society of Endocrinology and Nutrition has produced a document with practical, evidencebased recommendations for the surgical treatment of obesity. The review is structured in three parts. The first part defines the concepts of obesity and associated comorbidities, medical treatments, their results, and the indications and contraindications for surgical treatment, as well as the criteria for patient selection, pre- and perisurgical management, and assessment of special groups such as adolescents and the elderly. The second part discusses the different surgical techniques, approaches and comparative results, short- and long-term complications, the repercussions of weight loss on comorbidities, and the criteria for assessing the effectiveness of surgery. The third part discusses postsurgical follow-up, dietary control in the early and subsequent stages after surgery and the schedule for medical and laboratory follow-up, together with the different macro- and micronutrient supplements that should be used depending on the surgical technique employed. A final section is included on pregnancy and bariatric surgery, as well as tables and figures that complement the text. Although bariatric surgery continues to be a questionable treatment for obesity, the results correcting excess weight, with improvements in associated comorbidities and in quality of life, confirm that this option could be the treatment of choice in selected patients when the appropriate surgical technique and correct preand postoperative follow-up are employed
