Abstract: La menopausia se asocia a un aumento del peso corporal y a cambios en la distribución de grasa, describiéndose también niveles elevados de homocisteína, factores de riesgo cardiovascular asociados al déficit de estrógenos. El objetivo de este estudio fue evaluar índice de masa corporal (IMC), la circunferencia de cintura (CCi), el índice cintura-cadera (ICC), la homocisteína sérica en mujeres posmenopáusicas (n: 128). El diagnóstico nutricional antropométrico se determinó según IMC (OMS); se determinaron la CCi (normal <88cm, en riesgo >88cm), ICC (normal <0,8, en riesgo >0,8), homocisteína sérica (tHci) (ELISA): normal < 10mmol/L, en riesgo >10-15mmol/L, alta: >15mmol/L y estradiol (ELISA): <65pg/mL (posmenopausia). 65,9% presentaron sobrepeso/ obesidad. 47,3% y 82,2% en riesgo cardiometabólico según CCi e ICC. Hubo diferencia significativa para ICC y correlación positiva significativa entre indicadores antropométricos. 10% presentó riesgo e hiperhomocisteinemia. Este aminoácido no correlacionó con las variables evaluadas. Las mujeres evaluadas presentaron una alta frecuencia de sobrepeso-obesidad y una distribución de grasa tipo androide, presentando un alto riesgo para enfermedades cardiometabólicas. Menopause is associated with an increased body weight and changes in fat distribution, high levels of homocysteine and cardiovascular risk factors associated with estrogen deficiency. The objective was to evaluate body mass index (BMI), waist circumference (WC), waist/hip index (WHI), and serum homocysteine (Hct) levels in postmenopausal women (n 128). Nutritional status was diagnosed by BMI (WHO), WC (normal <88cm, at risk> 88cm), WHI (normal <0.8, at risk> 0.8), serum homocysteine (Hct) (ELISA) normal < 10 mmol/L, at risk >10-15mmol/L, high >15mmol/L and estradiol (ELISA) <65pg/mL (menopause). Sixty five point nine % were overweight/obese, 47.3% and 82.2% showed cardio metabolic risk by WC and WHI. There was a significant difference for WHI, and a positive significant correlation between anthropometrics indexes. Ten % showed risk and hyperhomocysteinaemia, but it was not correlated with the evaluated variables. The subjects had a high frequency of overweight, obesity and android fat distribution, showing a high risk for cardiometabolics diseases.

Abstract: Objective: To evaluate the effectiveness of a program of psychological preparation for invasive procedures in patients with heart disease, candidates for cardiac surgery, to reduce emotional morbidity and improve perception of health related quality of life. Methods: A Quasi-experimental design was used. The study included a non-probabilistic randomized sample of 110 patients treated in the Division of Cardiac Surgery Centro Medico Nacional Siglo XXI Instituto Mexicano del Seguro Social IMSS. They were divided in two groups: Experimental group (n = 44) and Control group (n = 66). Instruments: CHIP Coping Questionnaire, HADS Anxiety and Depression Hospital Scale, Health Related Quality of Life Questionnaire and a Visual Analogue Scale (VAS) to measure postoperative pain. Results: The experimental group showed an increase in instrumental coping style compared to pre (M = 24.55) and post evaluation (M = 25.93); statistically significant differences were found in the variables of stress (p = 0.042), anxiety (p = 0.001), depression (p = 0.056) and health related quality of life (p = 0.000); while in the control group, the distraction coping style (pre M = 25.80, post M = 26.73) is the one that increased; there were no statistically significant differences in the variables stress (p = 0.274), anxiety (p = 0.671) and depression (p = 0.850), except for the health related quality of life (p = 0.000). This study is the first in Mexico to manage emotional comorbidity in this type of population.

Abstract: background: although studies have demonstrated the occurrence of postexercise hypotension (peh) in resistance exercises, there is still no consensus on an ideal protocol. objective: to evaluate the effects of different rest intervals (ri) between resistance exercise (re) sets on postexercise blood pressure (bp). methods: sixteen sedentary non-hypertensive young men performed three re protocols with ri of 1 (p1), 2 (2) and 3 (p3) minutes between the sets, as well as a control protocol (con), in a counterbalanced manner. the re protocols consisted of three sets of eight repetitions in six exercises. the loads used in the 1st, 2nd, and 3rd exercise sets were 80%, 70% and 60% of one repetition maximum (1rm), respectively. measurements were taken at rest (res), 15 (t15), 30 (t30), 45 (t45), 60 (t60), 75 (t75), and 90 (t90) minutes after the session. factorial analysis of variance (anova) was carried out, followed by post hoc lsd. results: no significant change was found in systolic bp after the protocols. a significant increase in diastolic bp was verified after con at timepoints t45 and t90. significant reduction in diastolic bp occurred after p1 and p3, with duration of 30 and 15 minutes, respectively. no significant differences were found in the systolic and diastolic bp responses between the protocols with different ri. conclusion: ri does not seem to influence systolic bp reduction after an re session. however, reductions in diastolic bp (p1 and p3) lasting up to 30 minutes were observed.

Abstract: Presentamos el caso de un paciente varón de 29 a os con sospecha clínica de feocromocitoma previamente diagnosticado de una Neoplasia Endocrina Múltiple (MEN) tipo 2b. Se realizó una gammagrafía con 123I-metaiodobelcilguanidina (MIBG) que mostró captación patológica en ambas suprarrenales, sugestiva de feocromocitoma bilateral. El estudio de resonancia magnética (RMN) determinó la localización anatómica. El paciente fue sometido a suprarrenalectomía bilateral confirmándose el diagnóstico de feocromocitoma bilateral en anatomía patológica.We report a case of 29 years old man who was referred with the clinical symptoms of pheochromocytoma in a Multiple Endocrine Neoplasia (MEN) type 2b. 123I- metaiodobenzylguanidine (MIBG) scan revelead pathologic adrenal bilateral uptake described in bilateral pheochromocytoma. Anatomical localization was achieved by Magnetic Resonance (MRI). The patient was submitted to surgery for bilateral adrenal removal. Surgical pathology confirmed the diagnostic of pheochromocytoma in both adrenal glands.

Abstract:
Goblet cell carcinoid tumor is a rare clinical entity which is usually diagnosed either as acute appendicitis or advanced cancer. Its main characteristic is that the histological findings are between those of adenocarcinoma and typical carcinoid tumor of the appendix. Goblet cell carcinoid tumors appear almost exclusively in the appendix, and prognosis depends mainly on the stage and the subtype of the histological classification. We report three cases of goblet cell carcinoid tumor in the appendix with different clinical presentation and evolution: a 60-year-old male admitted to the emergency room with acute abdominal pain, diagnosed with acute appendicitis and treated with laparoscopic appendectomy; a 65-year-old male undergoing right hemicolectomy to remove a cecal adenoma, with a goblet cell carcinoid tumor found incidentally in the surgical specimen; and a 77-year-old male with acute appendicitis. We discuss the main pathological and clinical findings, and propose a set of guidelines for clinical practice.
Designs of studies published in two Brazilian journals of orthopedics and sports medicine, recently indexed in the ISI Web of Science
Riera, Rachel;
Sao Paulo Medical Journal , 2009, DOI: 10.1590/S1516-31802009000600007
Abstract: context and objective: the methodology and relevance of articles are among the keystones for promoting their citation and increasing journals' impact factors. study designs appropriate for answering the questions and adequate sample sizes have the aim of reducing the risk of bias. this study evaluated the articles published in two brazilian journals of orthopedics and sports medicine that were recently indexed in the isi web of science, regarding study design, sample size calculation, randomization and blinding. design and setting: descriptive study at brazilian cochrane center. methods: through a manual search, all original manuscripts published in 2007 in acta ortopédica brasileira and revista brasileira de medicina do esporte were selected and evaluated. results: all the 60 articles published in acta ortopédica brasileira and the 87 articles in revista brasileira de medicina do esporte were included and evaluated. the commonest design in acta ortopédica brasileira was experimental studies (n = 19) and in revista brasileira de medicina do esporte, update or review articles (n =14). sample calculations were seen in a minority of the articles. none of the eight clinical trials published presented sample calculations or adequate randomization processes. three were described as blinded, but none described the measures taken to prevent disclosure of the allocation concealment. conclusions: publication of studies of good methodological quality other than review and experimental studies should be strongly encouraged among brazilian journals, with the aim of increasing their citation and therefore their impact factor.

Llengua & Literatura , 2012, DOI: 10.2436/l&l.v0i0.60554
Abstract: En l’article es comprova el grau d’acceptació, per part del Gran diccionari de la llengua catalana (1998), de les propostes etimològiques de Joan Veny sobre una sèrie de mots estudiats en la seva obra Llengua i entorn natural (2001). The article examines the degree to which the Gran diccionari le la llengua catalana [‘Great Dictionary of the Catalan language’] (1998) accepted the etymological proposals of Joan Veny concerning a series of words presented in his book Llengua i entorn natural [‘Language and the Natural Environment’] (2001).
La abstención diferencial en la Espa a de las autonomías. Pautas significativas y mecanismos explicativos
Riera, Pedro
Revista Internacional de Sociologia , 2012,
Abstract: The implementation of the model of territorial organization established by the Spanish Constitution of 1978 involves the creation of non state-wide institutions with legislative powers, and the celebration of regional elections in order to decide the composition of the autonomous parliaments. The turnout registered in this type of contests is persistently and generally lower than in general elections. Those citizens that participate in the general but not in the regional elections are known as differential non-voters. Despite this pattern of non-voting is repeated election after election in all the communities, its magnitude and consequences differ in each case. In this paper, the causes of this variation are explored by using aggregated data of turnout in both types of elections across regions and over time. Results from the specified econometric models seem to point out the need to resort to several socio-demographic, political and institutional factors to explain differential abstention in the decentralized Spain. La implementación del modelo de organización territorial establecido por la Constitución espa ola de 1978 supone la creación de entidades no estatales con capacidad legislativa y la celebración de elecciones regionales para decidir la composición de los parlamentos autonómicos. La participación registrada en este tipo de comicios es persistente y generalizadamente más baja que la que se da en las elecciones a Cortes Generales. Aquellos ciudadanos que votan en las elecciones generales pero no en las autonómicas son conocidos como abstencionistas diferenciales. A pesar de que este patrón abstencionista se repite elección tras elección en todas las comunidades, su magnitud y consecuencias difieren en cada caso. En este trabajo se exploran las causas de esta variación utilizando los datos agregados de participación en ambos tipos de elecciones en cada autonomía y momento del tiempo. Los resultados de los modelos econométricos especificados parecen apuntar la necesidad de acudir a diversos factores sociodemográficos, políticos e institucionales para explicar la abstención diferencial en la Espa a autonómica.
