Validation of the Portuguese Version of EHP-30 (The Endometriosis Health Profile-30)

Introduction: Endometriosis Health Profile Questionnaire-30 is currently the most used questionnaire for quality of life measurement in women with endometriosis. The aim of this study is to evaluate the psychometric properties and to validate the Portuguese Endometriosis Health Profile Questionnaire-30 version. MATERIAL AND METHODS A sequential sample of 152 patients with endometriosis, followed in a Portugal reference center, were asked to complete a questionnaire on social and demographic features, the Portuguese version of the Endometriosis Health Profile Questionnaire-30 and of the Short Form Health Survey 36 Item â version 2. Appropriate statistical analysis was performed using descriptive statistics, factor analysis, internal consistency, item-total correlation and convergent validity. RESULTS Factorial analysis confirmed the validity of the five-dimension structure of the Endometriosis Health Profile Questionnaire-30 core questionnaire, which explained 83.2% of the total variance. All item-total correlations presented acceptable results and high internal consistency, with Cronbach's alpha ranging between 0.876 and 0.981 for the core questionnaire and between 0.863 and 0.951 for the modular questionnaire. Significant negative associations between similar scales of Endometriosis Health Profile Questionnaire-30 and Short Form Health Survey 36 Item â version 2 were demonstrated. Data completeness achieved was high for all dimensions. The emotional well-being scale in the core questionnaire and the infertility scale in the modular section had the highest median scores, and therefore the most negative impact on the quality of life of participating women. DISCUSSION The test-retest reliability and responsiveness of the questionnaire should be evaluated in future studies. CONCLUSION The present study demonstrates that the Portuguese version of the Endometriosis Health Profile Questionnaire-30 is a valid, reliable and acceptable tool for evaluating the health-related quality of life of Portuguese women with endometriosis.

Coronary artery disease, microalbuminuria and lipid profile in patients with non-insulin dependent diabetes mellitus

PURPOSE: To determine the frequency of coronary artery disease, microalbuminuria and the relation to lipid profile disorders, blood pressure and clinical and metabolic features. METHODS: Fifty-five type 2 diabetic patients (32 females, 23 males), aged 59.9±9 years and with known diabetes duration of 11±7.3 years were studied. Coronary artery disease (CAD) was defined as a positive history of myocardial infarction, typical angina, myocardial revascularization or a positive stress testing. Microalbuminuria was defined when two out of three overnight urine samples had a urinary albumin excretion ranging 20 - 200µg/min. RESULTS: CAD was present in 24 patients (43,6%). High blood pressure (HBP) present in 32 patients (58.2%) and was more frequent in CAD group (p=0.05) HBP. Increased the risk of CAD 3.7 times (CI[1.14-12]). Microalbuminuria was present in 25 patients (45.5%) and tended to associate with higher systolic blood pressure (SBP) (p = 0.06), presence of hypertension (p = 0.06) and know diabetes duration (p = 0.08). In the stepwise multiple logistic regression the systolic blood pressure was the only variable that influenced UAE (r = 0.39, r² = 0.14, p = 0.01). The h ypertensive patients had higher cholesterol levels (p = 0.04). CONCLUSION: In our sample the frequency of microalbuminuria, hypertension, hypercholesterolemia and CHD was high. Since diabetes is an independent risk factor for cardiovascular disease, the association of others risk factors suggest the need for an intensive therapeutic intervention in primary and in secundary prevention.

Lipid profile of nutrition students and its association with cardiovascular disease risk factors

OBJECTIVE: To describe the lipid profile and to verify its relationship with cardiovascular disease risk factors in students at a public university in São Paulo. METHODS: After obtaining clinical, anthropomorphic, and lipid profile data from 118 students, variables of the lipid profile were related to other risk factors. RESULTS: The mean age of the students was 20.3 years (SD=1.5). The risk of cardiovascular disease was characterized by a positive family history of ischemic heart disease in 38.9%; sedentariness in 35.6%; limiting and increased total and LDL-C cholesterol levels in 17.7% and 10.2%, respectively; decreased HDL-C levels in 11.1%; increased triglyceride levels in 11.1%; body mass index >25 in 8.5%, and smoking in 6.7% of the subjects. Students' diet was found to be inadequate regarding protein, total fat, saturated fat, sodium, and fiber contents. A statistically significant association between cholesterol and contraceptive use, between HDL-C and contraceptive use, age and percent body fat, and triglycerides and percent lean weight was observed. CONCLUSION: A high prevalence of some risk factors of cardiovascular disease as well as the association between these factors with altered lipid profiles was observed in the young population studied.

Changes in the profile of lipoprotein subfractions associated with hormone replacement therapy

OBJECTIVE: To report the effects of 2 regimens of hormone replacement therapy during the postmenopausal period on the profile of the major lipoprotein subfractions (HDL, LDL, and VLDL). METHODS: We carried out a cohort study in 38 postmenopausal patients who were starting their hormone replacement therapy due to gynecological indications, for a period of 12 weeks. Analysis of lipoprotein subclasses was performed through nuclear magnetic resonance spectroscopy. RESULTS: Hormone replacement therapy cause an increase in the proportion of larger subfractions of VLDL and HDL (p=0.008 and 0.03, respectively) and in the proportion of larger particles of VLDL due to a 36% increase in the levels of larger particles (p=0.004), concomitantly with a 15% reduction in the levels of smaller particles (p=0.04). In regard to HDL, the increase occurred only a 17% increase in the levels of larger particles (p=0.002). No significant change occurred in the distribution pattern of LDL subfractions. CONCLUSION: The proportion of larger subfractions of VLDL and HDL increases after hormone replacement therapy. The increase in the proportion of larger particles of VLDL occurs due to an increase in the levels of the larger subclasses concomitantly with a reduction in the smaller particles. However, an increase in the proportion of larger particles of HDL occurs only due to an increase in the levels of the larger subfractions.

Infants’ behavioral and physiological profile and mother–infant interaction

This study aims to (a) identify and profile groups of infants according to their behavioral and physiological characteristics, considering their neurobehavioral organization, social withdrawal behavior, and endocrine reactivity to stress, and to (b) analyze group differences in the quality of mother–infant interaction. Ninety seven 8-week-old infants were examined using the Neonatal Behavioral Assessment Scale and the Alarm Distress Baby Scale. Cortisol levels were measured both before and after routine inoculation between 8 and 12 weeks. At 12 to 16 weeks mother–infant interaction was assessed using the Global Rating Scales of Mother–Infant Interaction. Three groups of infants were identified: (a) ‘‘withdrawn’’; (b) ‘‘extroverted’’; (c) ‘‘underaroused.’’ Differences between them were found regarding both infant and mother behaviors in the interaction and the overall quality of mother–infant interaction. The identification of behavioral and physiological profiles in infants is an important step in the study of developmental pathways.

Infant’s psychophysiological profile and temperament at 3 and 12 months

This study is intended to analyze (1) differences in infant temperament at 3 and 12 months according to infants' psychophysiological profiles: "withdrawn" "extroverted", and "underaroused" and (2) changes in infant temperament from 3 to 12 months, namely according to the infant psychophysiological profile and the quality of mother-infant interaction. Ninety-four 8-week-old infants were assessed using the Neonatal Behavioral Assessment Scale (NBAS, Brazelton & Nugent, 1995) and the Alarm Distress Baby Scale (ADBB, Guedeney & Fermanian, 2001). Saliva samples were collected at 8-12 weeks old, both before and after a routine inoculation for cortisol reactivity measurement. Mother-infant interaction was evaluated at 12-16 weeks, using the Global Rating Scales (GRS, Murray, Fiori-Cowley, Hooper, & Cooper, 1996). Mothers' reports on infant temperament at 3 and 12 months were collected using the Infant Behavior Questionnaire (IBQ, Rothbart, 1981). Significant differences in mothers' perception of infant temperament were found at both 3 and 12 months in infants with distinct psychophysiological profiles. Stability was observed in most of the temperament's dimensions from 3 to 12 months old; still, there were changes in mothers' perception of infant temperament in terms of level of distress, cuddliness, sadness and approach. Infant psychophysiological profile and mother-infant interaction both influence with the pattern of those changes. The results corroborate that infant's characteristics early in life as well as contextual factors influence with mothers' perception of infant temperament and with changes across the 1st year of life.

O questionário apresenta elevada consistência interna (α=.90), e as sub-escalas têm valores de alpha de Cronbach compreendidos entre .50 e .84. Confirma-se também a validade externa dado que um elevado número de sub-escalas do PRP, se encontra significativamente correlacionado com a escala de abuso físico sem sequelas (CT52). Os resultados obtidos confirmam a validade da versão portuguesa do questionário PRP, possibilitando a investigadores e práticos no âmbito das relações maritais um instrumento de screening para sinalização, aprofundamento e orientação das linhas de acção específicas no tratamento e/ou investigação dos principais factores associados à violência conjugal.

Clinical Profile, Predictors of Mortality, and Treatment of Patients after Myocardial Infarction, in an Academic Medical Center Hospital

OBJECTIVE: To evaluate clinical profiles, predictors of 30-day mortality, and the adherence to international recommendations for the treatment of myocardial infarction in an academic medical center hospital. METHODS: We retrospectively studied 172 patients with acute myocardial infarction, admitted in the intensive care unit from January 1992 to December 1997. RESULTS: Most patients were male (68%), white (97%), and over 60 years old (59%). The main risk factor for coronary atherosclerotic disease was systemic blood hypertension (63%). Among all the variables studied, reperfusion therapy, smoking, hypertension, cardiogenic shock, and age were the predictors of 30-day mortality. Most commonly used medications were: acetylsalicylic acid (71%), nitrates (61%), diuretics (51%), angiotensin-converting enzyme inhibitors (46%), thrombolytic therapy (39%), and beta-blockers (35%). CONCLUSION: The absence of reperfusion therapy, smoking status, hypertension, cardiogenic shock, and advanced age are predictors of 30-day mortality in patients with acute myocardial infarction. In addition, some medications that are undoubtedly beneficial have been under-used after acute myocardial infarction.

New integrative computational approaches unveil the Saccharomyces cerevisiae pheno-metabolomic fermentative profile and allow strain selection for winemaking

During must fermentation by Saccharomyces cerevisiae strains thousands of volatile aroma compounds are formed. The objective of the present work was to adapt computational approaches to analyze pheno-metabolomic diversity of a S. cerevisiae strain collection with different origins. Phenotypic and genetic characterization together with individual must fermentations were performed, and metabolites relevant to aromatic profiles were determined. Experimental results were projected onto a common coordinates system, revealing 17 statistical-relevant multi-dimensional modules, combining sets of most-correlated features of noteworthy biological importance. The present method allowed, as a breakthrough, to combine genetic, phenotypic and metabolomic data, which has not been possible so far due to difficulties in comparing different types of data. Therefore, the proposed computational approach revealed as successful to shed light into the holistic characterization of S. cerevisiae pheno-metabolome in must fermentative conditions. This will allow the identification of combined relevant features with application in selection of good winemaking strains.

Acute myocardial infarction: clinical and epidemiological profile and factors associated with in-hospital death in the municipality of Rio de Janeiro

OBJECTIVE: To study the factors associated with the risk of in-hospital death in acute myocardial infarction in the Brazilian public health system in Rio de Janeiro, Brazil. METHODS: Sectional study of a sample with 391 randomly drawn medical records of the hospitalizations due to acute myocardial infarction recorded in the hospital information system in 1997. RESULTS: The diagnosis was confirmed in 91.7% of the cases; 61.5% males; age = 60.2 ± 2.4 years; delta time until hospitalization of 11 hours; 25.3% were diabetic; 58.1% were hypertensive; 82.6% were in Killip I class. In-hospital mortality was 20.6%. Thrombolysis was used in 19.5%; acetylsalicylic acid (ASA) 86.5%; beta-blockers 49%; angiotensin-converting enzyme (ACE) inhibitors 63.3%; calcium channel blockers 30.5%. Factors associated with increased death: age (61-80 years: OR=2.5; > 80 years: OR=9.6); Killip class (II: OR=1.9; III: OR=6; IV: OR=26.5); diabetes (OR=2.4); ventricular tachycardia (OR=8.5); ventricular fibrillation (OR=34); recurrent ischemia (OR=2.7). The use of ASA (OR=0.3), beta-blockers (OR=0.3), and ACE inhibitors (OR=0.4) was associated with a reduction in the chance of death. CONCLUSION: General lethality was high and some interventions of confirmed efficacy were underutilizated. The logistic model showed the beneficial effect of beta-blockers, and ACE inhibitors on the risk of in-hospital death.

Lipid profile and cardiovascular risk in two Amazonian populations

OBJECTIVE: To compare the lipid profiles and coronary heart disease risks of 2 Brazilian Amazonian populations as follows: a riverside population (village of Vigia) and an urban population (city of Belém in the state of Pará). METHODS: Fifty individuals controlled for age and sex were assessed in each region, and the major risk factors for coronary heart disease were analyzed. RESULTS: According to the National Cholesterol Education Program (NCEP III) and using the Framingham score, both populations had the same absolute risk of events (Vigia = 5.4 ± 1 vs Belém = 5.7 ± 1), although the population of Vigia had a lower consumption of saturated fat (P<0.0001), a greater consumption of mono- and polyunsaturated fat (P<0.03), in addition to lower values for body mass index (25.4± 0.6 vs 27.6 ± 0.7 kg/m², P<0.02), of biceps skin fold (18.6 ± 1.1 vs 27.5 ± 1.3 mm, P<0.0001), of triceps skin fold (28.7 ± 1.2 vs 37.3 ± 1.7 mm, P<0.002), and of total cholesterol (205 ± 5 vs 223 ± 6 mg/dL, P< 0.03) and triglycerides (119 ± 9 vs 177 ± 18 mg/dL, P<0.005). Both populations did not differ in regard to HDL-C (46 ± 1 vs 46 ± 1 mg/dL), LDL-C (135 ± 4 vs 144 ± 5 mg/dL) and blood pressure (SBP 124 ± 3 vs 128 ± 3 mmHg; DBP 80 ± 2 vs 82 ± 2 mmHg). CONCLUSION: The riverside and urban populations of Amazonia had similar cardiovascular risks. However, the marked difference in the variables studied suggests that different strategies of prevention should be applied.

Perfil neuropsicológico y sesgos cognitivos de adolescentes con diferentes patrones de consumo de alcohol. Neuropsychological profile and cognitive bias in adolescents with different alcohol consumption patterns.

Identificación y caracterización del problema objeto de estudio: Diversas investigaciones señalan que el uso o consumo de alcohol comienza durante la adolescencia. En este periodo del desarrollo típicamente se han reportado deterioros asociados con el consumo de alcohol sobre diversas funciones cognitivas. Sin embargo, los hallazgos no siempre han sido concluyentes. Hipótesis: a) Existe una mayor cantidad de déficits neuropsicológicos (especialmente en los dominios asociados con la toma de decisiones) en los grupos de adolescentes que presentan patrones de consumo elevados o tipo binge y en los adolescentes bajo tratamiento; b) Existen sesgos cognitivos de tipo implícito en los adolescentes expuestos a publicidades referidas a bebidas alcohólicas; y c) Existe mayor presencia de expectativas negativas en el grupo conformado por niños, así como una mayor presencia de expectativas positivas en el grupo conformado por adolescentes. Planteo de Objetivos: se pretende lograr un perfil neuropsicológico de adolescentes de ambos sexos en función de patrones de consumo de alcohol bien diferenciados. Asimismo, se intentará determinar la presencia de sesgos cognitivos hacia estímulos asociados con el alcohol en función de las expectativas hacia el psicotrópico y el tipo de consumo del mismo que presenta la población bajo estudio. Finalmente, se buscará determinar si existen cambios evolutivos en las expectativas hacia el alcohol que pudieran indicar la presencia de mayor vulnerabilidad al consumo de alcohol. Materiales y métodos a utilizar: Se utilizarán pruebas neuropsicológicas (IGT, WCST, otras) y cognitivas (AEQ o similares). Se apelará al uso de diseños ex post facto prospectivos de tipo simple o factoriales, diseños factoriales, estudios instrumentales y estudios descriptivos de poblaciones mediante encuestas. Resultados esperados: 1) Se espera encontrar una mayor cantidad de déficits neuropsicológicos (especialmente en los dominios asociados con la toma de decisiones) en los grupos de adolescentes con patrones de consumo de alcohol elevados y binge, así como en el grupo de adolescentes bajo tratamiento. 2) Se espera encontrar la presencia de sesgos cognitivos implícitos en aquellos adolescentes expuestos a publicidades referidas a bebidas alcohólicas en contraposición a los adolescentes expuestos a publicidades de bebidas no-alcohólicas. 3) Se espera encontrar una mayor presencia de expectativas negativas en el grupo conformado por niños, y una mayor presencia de expectativas positivas en el grupo conformado por adolescentes, con lo que se verificaría el supuesto que señala que las EA se modifican a lo largo del desarrollo. Asimismo, se espera confirmar que las EA cambian en función de la experiencia de consumo de alcohol. Importancia del proyecto: En el ámbito local no se han realizado estudios sistemáticos de esta naturaleza, la información que se obtenga permitirá evaluar el impacto del uso y abuso de alcohol durante la adolescencia así como diseñar y ejecutar mejores estrategias de prevención y de rehabilitación y, al mismo tiempo, facilitará la toma de decisiones en el campo de la planificación de políticas sanitarias dirigidas a los adolescentes.

Diseño de sistemas de comunicaciones de alta velocidad. Design of high-speed communication systems.

El crecimiento exponencial del tráfico de datos es uno de los mayores desafíos que enfrentan actualmente los sistemas de comunicaciones, debiendo los mismos ser capaces de soportar velocidades de procesamiento de datos cada vez mas altas. En particular, el consumo de potencia se ha transformado en uno de los parámetros de diseño más críticos, generando la necesidad de investigar el uso de nuevas arquitecturas y algoritmos para el procesamiento digital de la información. Por otro lado, el análisis y evaluación de nuevas técnicas de procesamiento presenta dificultades dadas las altas velocidades a las que deben operar, resultando frecuentemente ineficiente el uso de la simulación basada en software como método. En este contexto, el uso de electrónica programable ofrece una oportunidad a bajo costo donde no solo se evaluan nuevas técnicas de diseño de alta velocidad sino también se valida su implementación en desarrollos tecnológicos. El presente proyecto tiene como objetivo principal el estudio y desarrollo de nuevas arquitecturas y algoritmos en electrónica programable para el procesamiento de datos a alta velocidad. El método a utilizar será la programación en dispositivos FPGA (Field-Programmable Gate Array) que ofrecen una buena relación costo-beneficio y gran flexibilidad para integrarse con otros dispositivos de comunicaciones. Para la etapas de diseño, simulación y programación se utilizaran herramientas CAD (Computer-Aided Design) orientadas a sistemas electrónicos digitales. El proyecto beneficiara a estudiantes de grado y postgrado de carreras afines a la informática y las telecomunicaciones, contribuyendo al desarrollo de proyectos finales y tesis doctorales. Los resultados del proyecto serán publicados en conferencias y/o revistas nacionales e internacionales y divulgados a través de charlas de difusión y/o encuentros. El proyecto se enmarca dentro de un área de gran importancia para la Provincia de Córdoba, como lo es la informática y las telecomunicaciones, y promete generar conocimiento de gran valor agregado que pueda ser transferido a empresas tecnológicas de la Provincia de Córdoba a través de consultorias o desarrollos de productos.

The Irish Pub: past, present – whither the future?

The purpose of this research is to examine the main economic, legislative, and socio- cultural factors that are currently influencing the pub trade in Ireland and their specific impact on a sample of publicans in both Galway city and county. In approaching this task the author engaged in a comprehensive literature review on the origin, history and evolution of the Irish pub; examined the socio-cultural and economic role of the public house in Ireland and developed a profile of the Irish pub by undertaking a number of semi-structured interviews with pub owners from the area. In doing so, the author obtained the views and opinions of the publicans on the current state of their businesses, the extent to which patterns of trade have changed over recent years, the challenges and factors currently influencing their trade, the actions they believed to be necessary to promote the trade and address perceived difficulties and how they viewed the future of the pub business within the framework of the current regulatory regime. In light of this research, the author identified a number of key findings and put forward a series of recommendations designed to promote the future success and development of the pub trade in Ireland. The research established that public houses are currently operating under a very unfavourable regulatory framework that has resulted in the serious decline of the trade over the last decade. This decline appears to have coincided initially with the introduction of the ban on smoking in the workplace and was exacerbated further by the advent of more severe drink-driving laws, especially mandatory breath testing. Other unfavourable conditions include the high levels of excise duty, value added tax and local authority commercial rates. In addition to these regulatory factors, the research established that a major impediment to the pub trade is the unfair competition from supermarkets and other off-licence retail outlets and especially to the phenomenon of the below-cost selling of alcohol. The recession has also been a major contributory factor to the decline in the trade as also has been the trend towards lifestyle changes and home drinking mirroring the practice in some continental European countries.
