BackgroundNutritional parameters could influence self-perceived health and functional status of older adults.ObjectiveWe prospectively determined the association between diet quality and quality of life and activities of daily living.DesignThis was an observational cohort study in which total diet scores, reflecting adherence to dietary guidelines, were determined. Dietary intakes were assessed using a food frequency questionnaire at baseline. Total diet scores were allocated for intake of selected food groups and nutrients for each participant as described in the Australian Guide to Healthy Eating. Higher scores indicated closer adherence to dietary guidelines.Participants/settingIn Sydney, Australia, 1,305 and 895 participants (aged ≥55 years) with complete data were examined over 5 and 10 years, respectively.Main outcome variablesThe 36-Item Short-Form Survey assesses quality of life and has eight subscales representing dimensions of health and well-being; higher scores reflect better quality of life. Functional status was determined once at the 10-year follow-up by the Older Americans Resources and Services activities of daily living scale. This scale has 14 items: seven items assess basic activities of daily living (eg, eating and walking) and seven items assess instrumental activities of daily living (eg, shopping or housework).Statistical analyses performedNormalized 36-Item Short-Form Survey component scores were used in analysis of covariance to calculate multivariable adjusted mean scores. Logistic regression analysis was used to calculate adjusted odds ratios and 95% CIs to demonstrate the association between total diet score with the 5-year incidence of impaired activities of daily living.ResultsParticipants in the highest vs lowest quartile of baseline total diet scores had adjusted mean scores 5.6, 4.0, 5.3, and 2.6 units higher in these 36-Item Short-Form Survey domains 5 years later: physical function (Ptrend=0.003), general health (Ptrend=0.02), vitality (Ptrend=0.001), and physical composite score (Ptrend=0.003), respectively. Participants in the highest vs lowest quartile of baseline total diet scores had 50% reduced risk of impaired instrumental activites of daily living at follow-up (multivariable-adjusted Ptrend=0.03).ConclusionsHigher diet quality was prospectively associated with better quality of life and functional ability. 相似文献

Subterranean storage of carbon dioxide (CO2) has been proposed to diminish atmospheric increases of this greenhouse gas. To contribute to risk assessment of accidental release associated with handling, transport and storage, rats were exposed to high concentrations (targets 40, 43 and 50 volume %) of CO2. The oxygen concentrations dropped as a result, but were not supplemented. For each concentration, pairs of animals were exposed for different exposure durations to derive an exposure concentration–duration relation in which mortality is described as a function of Cn × t (probit relation). A very high “n” value for the probit function could be derived from the data obtained at 40% and 43% CO2, which indicates that for exposure durations longer than 30 min the LC50 decreases hardly with increasing exposure duration. Below 30 min the LC50 seemed to increase with decreasing exposure durations. The variability in the data of 43% and 50% CO2, however, did not allow to derive a meaningful value of “n”. 相似文献

A risk assessment study of dioxins in sanitary napkins produced in Japan was performed. The daily estimated exposure volume to dioxins was compared with the tolerable daily intake (TDI). The concentrations of dioxins such as polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and dioxin-like polychlorinated biphenyls (DL-PCBs) in seven sanitary napkins were measured using gas chromatography and mass spectroscopy analytical methods. Among the seven napkins, a range of 0.0044–0.076 pg TEQ/g dioxins was measured. Daily estimated exposure volume from sanitary napkins was calculated as follows: (dioxin volumes in a sanitary napkin (0.0044–0.076 pg TEQ/g) × pulp weight in a sanitary napkin (11.2 g) × used napkin numbers/d (7.5) × the number of days/month that women use sanitary napkins (7) × skin absorption rate (0.03) × used years (40))/(average body weight of women (50 kg) × the number of days in the month (30) × life years (86)). Daily exposure volumes were estimated to be 0.000024–0.00042 pg TEQ/kg/d. For hazard assessment, we used 0.7 pg TEQ/kg/d which was the lowest level of TDI among TDI values reported by international agencies. When the daily exposure volume was compared with the TDI, the former was approximately 1666–29,166 times less than the latter. This fact indicated that the risk of exposure to dioxins from sanitary napkins produced in Japan was negligible. 相似文献

Objectives:
The hospital standardized mortality ratio (HSMR) has been widely used because it allows for robust risk adjustment using administrative data and is important for improving the quality of patient care.Methods:
All inpatients discharged from hospitals with more than 700 beds (66 hospitals) in 2008 were eligible for inclusion. Using the claims data, 29 most responsible diagnosis (MRDx), accounting for 80% of all inpatient deaths among these hospitals, were identified, and inpatients with those MRDx were selected. The final study population included 703 571 inpatients including 27 718 (3.9% of all inpatients) in-hospital deaths. Using logistic regression, risk-adjusted models for predicting in-hospital mortality were created for each MRDx. The HSMR of individual hospitals was calculated for each MRDx using the model coefficients. The models included age, gender, income level, urgency of admission, diagnosis codes, disease-specific risk factors, and comorbidities. The Elixhauser comorbidity index was used to adjust for comorbidities.Results:
For 26 out of 29 MRDx, the c-statistics of these mortality prediction models were higher than 0.8 indicating excellent discriminative power. The HSMR greatly varied across hospitals and disease groups. The academic status of the hospital was the only factor significantly associated with the HSMR.Conclusions:
We found a large variation in HSMR among hospitals; therefore, efforts to reduce these variations including continuous monitoring and regular disclosure of the HSMR are required. 相似文献996.
