Abstract: testinal fermentation in patients with self-reported food hypersensitivity: painful, but protective? Original Research (4365) Total Article Views Authors: J rgen Valeur, Mette Helvik Morken, Elisabeth Norin, et al Published Date July 2010 Volume 2010:3 Pages 65 - 70 DOI: http://dx.doi.org/10.2147/CEG.S11349 J rgen Valeur1,2, Mette Helvik Morken1, Elisabeth Norin3, Tore Midtvedt3, Arnold Berstad1,2 1Institute of Medicine, University of Bergen, Bergen, Norway; 2Department of Medicine, Haukeland University Hospital, Bergen, Norway; 3Department of Microbiology, Tumor and Cell Biology, Karolinska Institutet, Stockholm, Sweden Purpose: Enterometabolic disturbances may cause meal-related symptoms. We performed a functional evaluation of the intestinal microflora in patients with unexplained, self-reported food hypersensitivity by measuring fecal short-chain fatty acids (SCFAs). Patients and methods: Thirty-five consecutive patients with self-reported food hypersensitivity and 15 healthy volunteers of similar age, gender, and body mass index collected all feces for 72 hours. Fecal concentrations of acetic, propionic, n-butyric, i-butyric, n-valeric, i-valeric, n-caproic, and i-caproic acids were analyzed by gas-liquid chromatography. Concentrations and excretions (output) of SCFAs in patients and controls were compared and related to gastrointestinal symptoms. Results: Despite nonsignificant differences between patients and controls for both total and individual SCFA concentrations and excretions, n-butyric acid comprised a higher (P = 0.035) and acetic acid a lower (P = 0.012) proportion of total SCFA in patients compared to controls. There were no significant correlations between symptom scores and concentrations or excretions of individual or total SCFAs, but the proportion of n-butyric acid was significantly higher in patients with severe symptoms compared to patients with moderate symptoms (P = 0.016). Conclusion: The results indicate an enterometabolic disturbance in patients with self-reported food hypersensitivity. Higher proportions of n-butyric acid may be related to abdominal symptom generation, but may also protect against organic bowel disease. Further studies are needed to clarify these aspects.

Manjiri D Pawaskar, Roger T Anderson, Rajesh Balkrishnan
Health and Quality of Life Outcomes , 2007, DOI: 10.1186/1477-7525-5-50
Abstract: A prospective cohort study was conducted by administrating health risk assessment questionnaire to elderly (≥65 years) with type 2 diabetes. Responses were linked with administrative claim's data. Data were obtained from elderly with type 2 diabetes who were enrolled in Medicare Health Maintenance Organization (HMO) in southeastern United States. The instrument collected information related to demographics, health status, medication use, and healthcare service utilization prior to enrollment. Responses were combined with the administrative claims data of HMO to obtain information on actual utilization of healthcare resources. The Short Form Center for Epidemiologic Studies Depression scale was used to assess depressive symptoms. Multivariable logistic regression analyses were conducted to determine predictor variables.Of 792 respondents, about 17% had depressive symptoms. Almost 96% of patients were using 1 or more antidiabetic medications. Overall, increased risk of depression was associated with lower health related quality of life (HRQoL) (OR: 0.97; 95% CI: 0.96–0.98) and higher impairments in instrumental activities of daily living (IADLs) (OR: 1.31; 95% CI: 1.14–0.52) in elderly patients. Poor health related quality of life (OR: 0.97, 95%CI: 0.95–0.99) was associated with higher risk of depression in patients on insulin therapy.Impairments in daily activities and lower HRQoL were predictors of depressive symptomatology in elderly with diabetes. Determinants of depression varied according to pharmacotherapeutic class of antidiabetic medications.Diabetes affects 20.8 million individuals and is considered as the sixth leading cause of death in the United States [1]. It poses an immense economic burden on the U.S. healthcare system costing around $100 billion annually [1]. Around 7 million elderly Americans suffer from type 2 diabetes mellitus. An elderly population in the United States is associated with maximum utilization of healthcare resources [2].Like diabete

Are self-reported measures valid for the assessment of nutritional status in the brazilian population?
Raildo da Silva Coqueiro,Lucélia Justino Borges,Valbério Candido Araújo,Andreia Pelegrini
Revista Brasileira de Cineantropometria e Desempenho Humano , 2009,
Abstract: Self-reported measures have been widely used for the assessment of nutritional status in epidemiological studies. This paper discusses aspects regarding the validity of self-reported measures of body weight and height for the assessment of nutritional statusin Brazilian children, adolescents, adults and elderly subjects. The available evidence suggests that: a) in children, the use of self-reported measures is not recommended because of the lack of Brazilian studies; b) in adolescents, these measures should be used with caution since the only study carried out in Brazil was restricted to a local sample and may not represent the situation in other regions; c) in adults, this method can be considereda viable alternative for assessing and monitoring nutritional status in situations in which these data cannot be measured directly; d) in the elderly, the use of self-reported measures cannot yet be recommended for two reasons: first, studies specifically includingsubjects older than 60 years have not been conducted and, second, this age group tends to estimate these measures less accurately.
Agency and Relationship Dissatisfaction Associated with Orthorexia Symptomatology  [PDF]
Crystal D. Oberle, Shelby L. Lipschuetz
Open Journal of Psychiatry (OJPsych) , 2018, DOI: 10.4236/ojpsych.2018.83027
Abstract: This study explored whether orthorexia symptomatology is linked to gender-related personality traits and to levels of satisfaction in one’s romantic relationships. Undergraduate students (418 women, 98 men) completed an online survey with measures to assess orthorexia symptomatology, agency, unmitigated agency, communion, unmitigated communion, and relationship satisfaction. Orthorexia symptomatology was positively correlated with levels of agency (r = 0.18; p < 0.001), but it was unrelated to unmitigated agency (p = 0.51), communion (p = 0.76), unmitigated communion (p = 0.17), and relationship status (p = 0.99). Among the participants who were in a committed relationship, symptomatology was negatively correlated with relationship satisfaction (p = 0.01), and this correlation was most pronounced for those with higher levels of unmitigated agency (p = 0.01). Orthorexia is associated with the agency personality trait, indicative of one’s need to be independent and to achieve personal accomplishments. However, particularly for those individuals whose agency becomes unmitigated, characterized by selfishness and avoidance of others, orthorexia symptomatology predicts significant dissatisfaction in romantic relationships.
