Nutritional management of individuals with Huntington’s disease: nutritional guidelines

The delivery of good nutritional care is a fundamental element of the management of individuals with Huntington’s disease and all patients with Huntington’s disease will, at some time, need dietary intervention because of the sequela of the disease; yet there are no European nutritional guidelines. The European Huntington’s Disease Network Standards of Care Dietitians Group has brought together expert dietitians from across Europe to produce nutritional guidelines to improve the nutritional management of individuals with Huntington’s disease. The guidelines were developed to promote optimal nutritional screening, assessment and management of individuals throughout all stages of the disease, with the aim of improving the standard of nutritional care delivered. Literature was systematically searched in an attempt to ensure that the recommendations are based on sound evidence and where evidence is lacking, specific guidance is based on consensus expert dietetic opinion. The provision of nutritional care varies widely between countries. Implementation of these nutritional guidelines across Europe should improve the quality of nutritional care delivered to individuals with Huntington’s disease

Consumption of alcohol, cigarettes and illegal substances among physicians and medical students in Brandenburg and Saxony (Germany)

<p>Abstract</p> <p>Background</p> <p>Patients regard health care professionals as role models for leading a healthy lifestyle. Health care professionals' own behaviour and attitudes concerning healthy lifestyle have an influence in counselling patients. The aim of this study was to assess consumption of alcohol, cigarettes and illegal substances among physicians and medical students in two German states: Brandenburg and Saxony.</p> <p>Methods</p> <p>Socio-demographic data and individual risk behaviour was collected by an anonymous self-administered questionnaire. Physicians were approached via mail and students were recruited during tutorials or lectures.</p> <p>Results</p> <p>41.6% of physicians and 60.9% of medical students responded to the questionnaire; more than 50% of the respondents in both groups were females. The majority of respondents consumed alcohol at least once per week; median daily alcohol consumption ranged from 3.88 g/d (female medical students) to 12.6 g/d (male physicians). A significantly higher percentage of men (p < 0.05) reported hazardous or harmful drinking compared to women. A quarter of all participating physicians and one third of all students indicated unhealthy alcohol-drinking behaviour. The majority of physicians (85.7%) and medical students (78.5%) were non-smokers. Both groups contained significantly more female non-smokers (p < 0.05). Use of illegal substances was considerably lower in physicians (5.1%) than medical students (33.0%). Male students indicated a significantly (p < 0.001) higher level of illegal drug-use compared to female students.</p> <p>Conclusion</p> <p>More than one third of the medical students and health care professionals showed problematic alcohol-drinking behaviour. Although the proportion of non-smokers in the investigated sample was higher than in the general population, when compared to the general population, medical students between 18-24 reported higher consumption of illegal substances.</p> <p>These results indicate that methods for educating and promoting healthy lifestyle, particularly with respect to excessive alcohol consumption, tobacco use and abuse of illegal drugs should be considered.</p

Assessment of micronutrient status during pregnancy attending at Kanpur, Uttar Pradesh, India

Background: This impression of multiple micronutrients during pregnancy emphasizes to relatively neglected issues. Objectives was to evaluate the status and benefits of multiple micronutrient during pregnancy.Methods: Total 180 healthy pregnant women were included, first trimester 60 cases, second trimester 60 cases and third trimester 60 cases in the age group of 18-40 years. Haemoglobin was estimated by cyanmethemoglobin method, estimation of iron was done by ferrozine method, for zinc colorimetric method, estimation of calcium OCPC method and estimation of urinary iodine was done by ammonium persulfate oxidation method.Results: Haemoglobin are found to be in the Ist trimester 11.3g/dl, in the IInd trimester of haemoglobin 10.5g/dl, and in the IIIrd trimester it was 11g/dl and Serum iron was 71.9ug/dl in Ist trimester, 74.8 ug/dl during IInd trimester, 80.9ug/dl in IIIrd trimester. The mean serum calcium during Ist trimester was found to be 8.0 ug/dl, in the IInd trimester 7.2 ug/dl and in the IIIrd trimester 8.1ug/dl. Serum zinc in the Ist trimester 72.6 ug/dl, in the IInd trimester 70.1ug/dl, in the IIIrd trimester 66.7 ug/dl respectively. Iodine level during Ist, IInd, IIIrd trimester was found to be 122.5ug/dl, 149.1ug/d, 158.7ug/dl respectively.Conclusions: Our study shows that poor nutrition during pregnancy has been associated with adverse maternal and child outcomes such as increased risks of infertility, abortion, fetal intrauterine growth restriction and prenatal mortality

El ejercicio agudo aumenta las concentraciones de homocisteína en varones físicamente activos

Introducción: Niveles altos de Homocisteína (Hcy) se han identificado como un factor de riesgo cardiovascular. En relación con la práctica de ejercicio físico, los resultados son contradictorios. Objetivos: El objetivo del presente estudio fue determinar la influencia de ejercicios agudos máximo y submáximo sobre las concentraciones de homocisteína total (tHcy) y otros parámetros sanguíneos relacionados. Material y métodos: Diez varones (23,5 ± 1,8 años) físicamente activos realizaron una prueba incremental máxima y otra submáxima a una intensidad del 65% del consumo máximo de oxígeno (VO2max) en tapiz rodante. Se analizaron antes y después las concentraciones de tHcy, folato, vitamina B12 y creatinina séricas. Resultados: Las concentraciones de tHcy séricas aumentaron significativamente tras las pruebas de intensidad máxima (p < 0,05) y submáxima (p < 0,01). El folato y la vitamina B12 también aumentaron significativamente tras ambas pruebas (p < 0,05). Las concentraciones de creatinina aumentaron significativamente únicamente en la prueba máxima (p < 0,001). Se encontró una relación inversa entre los niveles de folato y de tHcy en todos los puntos (p < 0,05). Conclusión: Se observaron niveles altos de homocisteína después del ejercicio agudo tanto máximo como submáximo

The choice of indicators influences conclusions about the educational gradient of sex-specific alcohol consumption

There has been considerable public interest in reports on harmful alcohol consumption of higher educated females. This study assesses the robustness of this finding with representative German data using ten different indicators of alcohol consumption. This cross-sectional study used data of the Epidemiological Survey on Substance Abuse from 2012. 4,225 females and 3,239 males represent the German population aged 18-64. It presents ten indicators of alcohol consumption by sex and education and provides group specific means and 95 %-confidence intervals. The main results are: (1) Higher educated males and females are drinking alcohol more frequently than lower educated males and females. (2) When drinking, higher educated males and females tend to drink less alcohol than lower educated males and females. (3) Only when using an indicator for hazardous alcohol consumption with different thresholds for males and females, the results indicate a pattern that significantly exposes hazardous alcohol consumption in the group of higher educated females. Concerning the choice of indicators, this study shows that sex-specific threshold-based indicators of alcohol consumption may lead to different conclusions as the majority of other indicators

Malnutrition, functional ability and mortality among older people aged ⩾60 years: a 7-year longitudinal study

BACKGROUND/OBJECTIVES: This study aimed to assess the association between risk of malnutrition and 7-year mortality, controlling for functional ability, socio-demographics, lifestyle behavior and diseases, and investigate the interaction between risk of malnutrition and functional ability on the risk of mortality. SUBJECTS/METHODS: A longitudinal study on home-living and special-housing residents aged [greater than or equal to] 60 years was conducted. Of 2312 randomly invited participants, 1402 responded and 1203 provided information on both nutritional status and functional ability. The risk of malnutrition was estimated by the occurrence of at least one anthropometric measure (BMI, MAC and CC) below cut-off in addition to the presence of at least one subjective measure (decreased food intake, weight loss and eating difficulty). RESULTS: At baseline, 8.6% of subjects were at risk of malnutrition and during the 7-year follow-up 34.6% subjects died. The risk of malnutrition was independently associated with 7-year mortality (hazard ratio (HR) 1.84, 95% confidence interval (CI) 1.28-2.65). Additional independent predictors were dementia (HR 2.76, 95% CI 1.85-4.10), activity of daily living (ADL) dependence (HR 2.08, 95% CI 1.62-2.67), heart disease (HR 1.44, 95% CI 1.16-1.78), diabetes (HR 1.41, 95% CI 1.03-1.93) and older age (HR 1.09, 95% CI 1.07-1.10). Moreover, the risk of malnutrition and ADL dependence in combination predicted the poorest survival rate (18.7%, P < 0.001). CONCLUSIONS: The risk of malnutrition significantly increases the risk of mortality in older people. Moreover, risk of malnutrition and ADL dependence together explain a significantly poorer survival rate; however, the importance of this interaction decreased in the multivariable model and risk of malnutrition and ADL dependence independently explained a significant risk of mortality

Biomarkers of physical activity and exercise

Tradicionalmente, los biomarcadores han sido de interés en las ciencias del deporte para medir el rendimiento, el progreso en el entrenamiento y para identificar el sobreentrenamiento. Durante los últimos años, cada vez hay mayor interés en evaluar los efectos relacionados con la salud que se producen en el organismo debidos a una actividad física regular y al deporte. El valor o la concentración de un biomarcador depende de muchos factores, como el grado de entrenamiento, el grado de fatiga y del tipo, la intensidad y la duración del ejercicio, aparte de la edad y del sexo. La mayor parte de los biomarcadores se miden en sangre, orina y saliva. Una de las principales limitaciones que presentan los biomarcadores bioquímicos es la falta de valores de referencia adaptados específicamente para deportistas y personas físicamente activas. Las concentraciones pueden variar considerablemente de los valores de referencia normales. Por lo tanto, es importante adaptar los valores de referencia siempre y cuando sea posible y controlar a cada sujeto regularmente, con el fin de establecer su propia escala de referencia. Otros biomarcadores útiles son la composición corporal (específicamente masa muscular, masa grasa, peso), la condición física (capacidad cardiorrespiratoria, fuerza, agilidad, flexibilidad), frecuencia cardíaca y presión arterial. Dependiendo de la finalidad, será conveniente analizar uno o varios biomarcadores. Para esta revisión, profundizaremos en los biomarcadores que se emplean para evaluar condición física, fatiga crónica, sobreentrenamiento, riesgo cardiovascular, estrés oxidativo e inflamación

Consistency of vitamin and/or mineral supplement use and demographic, lifestyle and health-status predictors: findings from the European Prospective Investigation into Cancer and Nutrition (EPIC)-Heidelberg cohort

Cross-sectional studies suggest that dietary supplement use is associated with favourable demographic and lifestyle factors and certain health conditions. However, factors that affect the consistency of supplement use have not been investigated in prospective cohort studies. The aim of the present study was to seek baseline demographic, lifestyle and health-status predictors of subsequent consistent vitamin and/or mineral supplement use. A total of 8968 men and 10672 women of the European Prospective Investigation into Cancer and Nutrition (EPIC)-Heidelberg cohort, who answered the supplement-use questions in the baseline survey and two follow-up surveys, were categorised into three groups: consistent, inconsistent and never users. At baseline, 28·5% of men and 38·6% of women reported vitamin and/or mineral supplement use. After a median follow-up of 8·5 years, 14·6% of men and 22·9% of women were consistent users. During follow-up, 36·0% of male and 26·6% of female initial users stopped supplement use, whereas 27·8% of male and 39·4% of female initial non-users started supplement use. Women were more likely to be consistent users than men. Older age (≥50 years), lower BMI (<25kg/m2) and self-reported hyperlipidaemia were common predictors of consistent use for both sexes. Additional predictors included higher educational level for men, and being more physically active and higher lifetime alcohol consumption for women. Consistent users had the highest intake of dairy products, fish, fruits and vegetables, and wine but the lowest intake of total meat. We concluded that supplement use is a fairly unstable behaviour in free-living individuals. Individuals with a favourable lifestyle and healthier diet are more likely to show consistent supplementatio

Novel bleeding risk score for patients with atrial fibrillation on oral anticoagulants, including direct oral anticoagulants

Objective: Balancing bleeding risk and stroke risk in patients with atrial fibrillation (AF) is a common challenge. Though several bleeding risk scores exist, most have not included patients on direct oral anticoagulants (DOACs). We aimed at developing a novel bleeding risk score for patients with AF on oral anticoagulants (OAC) including both vitamin K antagonists (VKA) and DOACs. Methods: We included patients with AF on OACs from a prospective multicenter cohort study in Switzerland (SWISS-AF). The outcome was time to first bleeding. Bleeding events were defined as major or clinically relevant non-major bleeding. We used backward elimination to identify bleeding risk variables. We derived the score using a point score system based on the β-coefficients from the multivariable model. We used the Brier score for model calibration (&lt;0.25 indicating good calibration), and Harrel's c-statistics for model discrimination. Results: We included 2147 patients with AF on OAC (72.5% male, mean age 73.4&nbsp;±&nbsp;8.2&nbsp;years), of whom 1209 (56.3%) took DOACs. After a follow-up of 4.4&nbsp;years, a total of 255 (11.9%) bleeding events occurred. After backward elimination, age&nbsp;&gt;&nbsp;75&nbsp;years, history of cancer, prior major hemorrhage, and arterial hypertension remained in the final prediction model. The Brier score was 0.23 (95% confidence interval [CI] 0.19–0.27), the c-statistic at 12&nbsp;months was 0.71 (95% CI 0.63–0.80). Conclusion: In this prospective cohort study of AF patients and predominantly DOAC users, we successfully derived a bleeding risk prediction model with good calibration and discrimination
