The authors automated the selection of foods in a computer system that compiles and processes tailored FFQ. For the selection of food items, several methods are available. The aim of the present study was to compare food lists made by MOM2, which identifies food items with highest between-person variance in intake of the nutrients of interest without taking other items into account, with food lists made by forward regression. The name MOM2 refers to the variance, which is the second moment of the nutrient intake distribution. Food items were selected for the nutrients of interest from 2 d of recorded intake in 3524 adults aged 25-65 years. Food lists by 80% MOM2 were compared to those by 80% explained variance for regression on differences between the number and type of food items, and were evaluated on (1) the percentage of explained variance and (2) percentage contribution to population intake computed for the selected items on the food list. MOM2 selected the same food items for Ca, a few more for fat and vitamin C, and a few less for carbohydrates and dietary fibre than forward regression. Food lists by MOM2 based on 80% of variance in intake covered 75-87% of explained variance for different nutrients by regression and contributed 53-75% to total population intake. Concluding, for developing food lists of FFQ, it appears sufficient to select food items based on the contribution to variance in nutrient intake without taking covariance into account.

Goals Of Work: In preterminal cancer patients, provision of palliative care in the patients' own environment is preferred. The aim of the present study was to evaluate patients' and caregivers' treatment adherence and patients' acceptance of home infusions with adenosine 5'-triphosphate (ATP).Patients and Methods: Preterminal cancer patients (life expectancy <6 months) with mixed tumor types were eligible for the study. Patients received a maximum of eight weekly intravenous 8-10 h ATP infusions. Evaluation of treatment adherence was based on registration of protocol deviations and patients' acceptance by structured interviews with patients.Main Results: Fifty-one patients received a total of 266 intravenous ATP infusions. The infusion protocol was well executed: mean duration approximately 8.30 h, stepwise achievement of the maximum infusion rate within 30 min in 65% of the infusions, and almost no delay in weekly administration. All except one patient were not burdened by the administration of the infusions at home and none of them had felt afraid. The majority of patients found the advantages of the ATP infusions outweighing the disadvantages. However, an important bottleneck in the administration of ATP infusions at home was difficulty in establishing venous access.Conclusion: ATP infusions at home are well accepted by patients. Difficulties in establishing venous access might be reduced by composing specialized home infusion teams working both at the day care center and at home or by adopting an alternative route of venous access.

Background: Dietary flavonoids are suggested to have antiobesity effects. Prospective evidence of an association between flavonoids and body mass index (BMI) is lacking in general populations.Objective: We assessed this association between 3 flavonoid subgroups and BMI over a 14-y period in 4280 men and women aged 55-69 y at baseline from the Netherlands Cohort Study.Design: Dietary intake was estimated at baseline (1986) by a validated food-frequency questionnaire. BMI was ascertained through self-reported height (in 1986) and weight (in 1986, 1992, and 2000). Analyses were based on sex-specific quintiles for the total intake of 6 catechins and of 3 flavonols/flavones. Linear mixed effect modeling was used to assess longitudinal associations in 3 adjusted models: age only, lifestyle (age, energy intake, physical activity, smoking status, alcohol intake, type 2 diabetes, and coffee consumption), and lifestyle and diet (vegetables, fruit, fiber, grains, sugar, dessert, and dieting habits).Results: After adjustment for age and confounders, the BMI (kg/m[2]) of women with the lowest intake of total flavonols/flavones and total catechins increased by 0.95 and 0.77, respectively, after 14 y. Women with the highest intake of total flavonols/flavones and total catechins experienced a significantly lower increase in BMI of 0.40 and 0.31, respectively (between group difference: P < 0.05). This difference remained after additional adjustment for dietary determinants and after stratification of median baseline BMI. In men, no significant differences in BMI change were observed over the quintiles of flavonoid intake after 14 y.Conclusion: Our results suggest that flavonoid intake may contribute to maintaining body weight in the general female population. © American Society for Nutrition [ABSTRACT FROM AUTHOR]

This study investigated the minimally required feedback elements of a computer-tailored dietary fat reduction intervention to be effective in improving fat intake. In all 588 Healthy Dutch adults were randomly allocated to one of four conditions in an randomized controlled trial: (i) feedback on dietary fat intake [personal feedback (P feedback)], (ii) P feedback and feedback on one's own behavior relative to that of peers [personal-normative feedback (PN feedback)], (iii) PN feedback and practical suggestions on how to change fat intake [personal-normative-action feedback (PNA feedback)] and (iv) generic information. Data on fat intake, awareness of one's own fat intake and intention to change were collected 1 and 6 months post-intervention. Between-group differences were tested with analysis of variance. Among respondents with high fat intakes at baseline (risk consumers) and those who underestimated their fat intake at baseline (underestimators), differences in awareness and (saturated) fat intake were found between the generic and PNA feedback conditions. Compared with generic information P feedback was more effective in changing awareness and intention among the underestimators, and PN feedback was more effective in changing intention among both risk consumers and underestimators. In conclusion, the combination of personal, normative and action feedback is required for inducing change in fat intake and improving awareness of fat intake. [ABSTRACT FROM AUTHOR]

OBJECTIVES: To examine psychosocial predictors of changes in fruit and vegetable consumption. METHODS: Baseline psychosocial variables were used to explain differences in changes in consumption in 83 healthy women with children after they received free fruit and vegetables for one month. RESULTS: One-month changes in fruit consumption (mean 144; SE 16 g/day) were positively associated with perceived costs and perceived health benefits for the children, and negatively associated with perceived behavioral control. Changes in vegetable consumption (68 (11) g/day) were positively related with the intention to eat at least 200 g of vegetables and taste preferences of the children. CONCLUSIONS: Fruit and vegetable consumption may be encouraged by influencing the above variables. [ABSTRACT FROM AUTHOR]

BACKGROUND: Studies suggest that low concentrations of n-6 long-chain polyenes in early life are correlated to atopic disease in later life. OBJECTIVE: The purpose of the study was to investigate the possible preventive effect of gamma-linolenic acid (GLA) supplementation on the development of atopic dermatitis in infants at risk. DESIGN: In a double-blind, randomized, placebo-controlled trial, formula-fed infants (n = 118) with a maternal history of atopic disease received borage oil supplement (containing 100 mg GLA) or sunflower oil supplement as a placebo daily for the first 6 mo of life. Main outcome measures were the incidence of atopic dermatitis in the first year of life (by UK Working Party criteria), the severity of atopic dermatitis (SCORing Atopic Dermatitis; SCORAD), and the total serum immunoglobulin E (IgE) concentration at the age of 1 y. RESULTS: The intention-to-treat analysis showed a favorable trend for severity of atopic dermatitis associated with GLA supplementation ( x+/- SD SCORAD: 6.32 +/- 5.32) in the GLA-supplemented group as compared with 8.28 +/- 6.54 in the placebo group (P = 0.09; P = 0.06 after adjustment for total serum IgE at baseline, age 1 wk), but no significant effects on the other atopic outcomes. The increase in GLA concentrations in plasma phospholipids between baseline and 3 mo was negatively associated with the severity of atopic dermatitis at 1 y (Spearman's correlation coefficient = -0.233, P = 0.013). There was no significant effect on total serum IgE concentration. CONCLUSION: Early supplementation with GLA in children at high familial risk does not prevent the expression of atopy as reflected by total serum IgE, but it tends to alleviate the severity of atopic dermatitis in later infancy in these children.

Abstract: Aim: The Western diet typically consists of high levels of saturated fat from animal products and has been associated with an increased risk of bladder cancer. Whilst olive oil, the predominant fat in the Mediterranean diet, has been associated with many health benefits its role in bladder cancer aetiology is still unknown. Therefore, we investigated the effect of intake of animal products, olive oil and other major dietary fats on bladder cancer risk. Methods: Dietary data were collected from 200 cases and 386 controls participating in a Belgian case–control study on bladder cancer. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) by comparing the highest with the lowest tertiles of intake between cases and controls using unconditional logistic regression. Adjustment was made for age, sex, smoking characteristics, occupational exposures and calorie intake. Results: There was a statistically significant inverse association between olive oil intake and bladder cancer consistent with a linear dose–response relationship: middle versus the lowest tertile (OR: 0.62; 95% CI: 0.39–0.99) and the highest versus the lowest tertile (OR: 0.47; 95% CI: 0.28–0.78; p-trend=0.002). We also observed borderline statistically significant increased odds of bladder cancer for the highest versus the lowest intake of cheese (OR: 1.53; 95% CI: 0.95–2.46; p-trend=0.08). No potential associations were detected for any other source or type of dietary fat. Conclusion: We observed evidence for a protective effect by olive oil and a possible increased risk of bladder cancer associated with a high intake of cheese. Our results require further investigation and confirmation by other studies. [ABSTRACT FROM AUTHOR]

Background: Obesity may affect an individual's immune response and subsequent risk of infection, such as a SARS-CoV-2 infection. It is less clear whether overweight and long-term obesity also constitute risk factors. We investigated the association between the degree and duration of overweight and obesity and SARS-CoV-2 infection., Methods: We analyzed data from nine prospective population-based cohorts of the Netherlands Cohorts Consortium, with a total of 99,570 participants, following a standardized procedure. Body mass index (BMI) and waist circumference (WC) were assessed two times before the pandemic, with approximately 5 years between measurements. SARS-CoV-2 infection was defined by self-report as a positive PCR or rapid-antigen test or as COVID-19 ascertained by a physician between March 2020 and January 2023. For three cohorts, information on SARS-CoV-2 infection by serology was available. Results were pooled using random-effects meta-analyses and adjusted for age, sex, educational level, and number of SARS-CoV-2 infection measurements., Results: Individuals with overweight (25 ≤ BMI < 30 kg/m 2 ) (odds ratio (OR) = 1.08, 95%-confidence interval (CI) 1.04-1.13) or obesity (BMI ≥ 30 kg/m 2 ) (OR = 1.43, 95%-CI 1.18-1.75) were more likely to report SARS-CoV-2 infection than individuals with a healthy body weight. We observed comparable ORs for abdominal overweight (men: 94 cm≤WC < 102 cm, women: 80 cm≤WC < 88 cm) (OR = 1.09, 95%-CI 1.04-1.14, I 2  = 0%) and abdominal obesity (men: WC ≥ 102 cm, women: WC ≥ 88 cm) (OR = 1.24, 95%-CI 0.999-1.55, I 2  = 57%). Individuals with obesity long before the pandemic, but with a healthy body weight or overweight just before the pandemic, were not at increased risk., Conclusion: Overweight and obesity were associated with increased risk of SARS-CoV-2 infection with stronger associations for obesity. Individuals with a healthier weight prior to the pandemic but previous obesity did not have an increased risk of SARS-CoV-2, suggesting that weight loss in those with obesity reduces infection risk. These results underline the importance of obesity prevention and weight management for public health., (© 2024. The Author(s).)

Background: Epidemiological and toxicological studies indicate that increased exposure to air pollutants can lead to neurodegenerative diseases. To further confirm this relationship, we evaluated the association between exposure to ambient air pollutants and corneal nerve measures as a surrogate for neurodegeneration, using corneal confocal microscopy., Methods: We used population-based observational cross-sectional data from The Maastricht Study including N = 3635 participants (mean age 59.3 years, 51.6% were women, and 19.9% had type 2 diabetes) living in the Maastricht area. Using the Geoscience and hEalth Cohort COnsortium (GECCO) data we linked the yearly average exposure levels of ambient air pollutants at home address-level [particulate matter with diameters of ≤ 2.5 µm (PM2.5), and ≤ 10.0 µm (PM10), nitrogen dioxide (NO2), and elemental carbon (EC)]. We used linear regression analysis to study the associations between Z-score for ambient air pollutants concentrations (PM 2.5 , PM 10 , NO 2 , and EC) and Z-score for individual corneal nerve measures (corneal nerve bifurcation density, corneal nerve density, corneal nerve length, and fractal dimension)., Results: After adjustment for potential confounders (age, sex, level of education, glucose metabolism status, corneal confocal microscopy lag time, inclusion year of participants, smoking status, and alcohol consumption), higher Z-scores for PM 2.5 and PM 10 were associated with lower Z-scores for corneal nerve bifurcation density, nerve density, nerve length, and nerve fractal dimension [stβ (95% CI): PM 2.5 -0.10 (-0.14; -0.05), -0.04 (-0.09; 0.01), -0.11 (-0.16; -0.06), -0.20 (-0.24; -0.15); and PM 10 -0.08 (-0.13; -0.03), -0.04 (-0.09; 0.01), -0.08 (-0.13; -0.04), -0.17 (-0.21; -0.12)], respectively. No associations were found between NO 2 and EC and corneal nerve measures., Conclusions: Our population-based study demonstrated that exposure to higher levels of PM 2.5 and PM 10 are associated with higher levels of corneal neurodegeneration, estimated from lower corneal nerve measures. Our results suggest that air pollution may be a determinant for neurodegeneration assessed in the cornea and may impact the ocular surface health as well., (© 2024. The Author(s).)

We determined the prognostic value of nutritional status for outcome after hip fracture. Nutritional status was a strong independent prognostic factor for clinical outcome and 5-year mortality. Physical function showed incomplete recovery. Elderly care should focus on prevention already before hip fracture., Purpose: To determine the prognostic value of nutritional status in hip fracture patients for multiple clinical and functional outcomes over 6 months, and for new fractures and survival over 5 years post-fracture., Methods: We included 152 well-characterized subjects (age 55+ years) with a hip fracture from a previously published randomized controlled trial. Nutritional status was appraised using the Mini Nutritional Assessment (MNA). Multivariable linear, logistic and Cox regression models were fitted, adjusted for age, sex, ASA score, group and additional prognostic covariates identified in backward regression models., Results: At baseline, impaired nutritional status was significantly associated with physical disability, depression, impaired cognition and lower quality of life. Prospective analyses showed that impaired baseline nutritional status was an independent prognostic factor for postoperative complications (OR 2.00, 95%CI 1.01-3.98, p = 0.047), discharge location from hospital (home vs. rehabilitation clinic, OR 0.41, 95%CI 0.18-0.98, p = 0.044), hospital readmission (OR 4.59, 95%CI 1.70-12.4, p = 0.003) and total length of hospital stay (HR of being discharged: 0.63, 96%CI 0.44-0.89, p = 0.008), as well as for 5-year mortality (HR 3.94, 95%CI 1.53-10.2, p = 0.005), but not for risk of new fractures (5y-HR 0.87, 95%CI 0.34-2.24, p = 0.769). Curves of physical disability over time showed that the three nutritional status categories followed almost parallel trajectories from baseline until 6 months after hip fracture, without complete recovery and even with further deterioration in malnourished subjects from 3 to 6 months post-fracture., Conclusion: As baselline nutritional status is a strong independent prognostic factor for clinical outcome after hip fracture, affecting even five-year survival, elderly health care should focus on prevention and identification of at-risk individuals already before hip fracture., (© 2024.

Introduction: The retina may provide non-invasive, scalable biomarkers for monitoring cerebral neurodegeneration., Methods: We used cross-sectional data from The Maastricht study (n = 3436; mean age 59.3 years; 48% men; and 21% with type 2 diabetes [the latter oversampled by design]). We evaluated associations of retinal nerve fiber layer, ganglion cell layer, and inner plexiform layer thicknesses with cognitive performance and magnetic resonance imaging indices (global grey and white matter volume, hippocampal volume, whole brain node degree, global efficiency, clustering coefficient, and local efficiency)., Results: After adjustment, lower thicknesses of most inner retinal layers were significantly associated with worse cognitive performance, lower grey and white matter volume, lower hippocampal volume, and worse brain white matter network structure assessed from lower whole brain node degree, lower global efficiency, higher clustering coefficient, and higher local efficiency., Discussion: The retina may provide biomarkers that are informative of cerebral neurodegenerative changes in the pathobiology of dementia., (© 2023 The Authors.

Aims/hypothesis: To assess the associations between glucose metabolism status and a range of continuous measures of glycaemia with corneal nerve fibre measures, as assessed using corneal confocal microscopy., Methods: We used population-based observational cross-sectional data from the Maastricht Study of N=3471 participants (mean age 59.4 years, 48.4% men, 14.7% with prediabetes, 21.0% with type 2 diabetes) to study the associations, after adjustment for demographic, cardiovascular risk and lifestyle factors, between glucose metabolism status (prediabetes and type 2 diabetes vs normal glucose metabolism) plus measures of glycaemia (fasting plasma glucose, 2 h post-load glucose, HbA 1c , skin autofluorescence [SAF] and duration of diabetes) and composite Z-scores of corneal nerve fibre measures or individual corneal nerve fibre measures (corneal nerve bifurcation density, corneal nerve density, corneal nerve length and fractal dimension). We used linear regression analysis, and, for glucose metabolism status, performed a linear trend analysis., Results: After full adjustment, a more adverse glucose metabolism status was associated with a lower composite Z-score for corneal nerve fibre measures (β coefficients [95% CI], prediabetes vs normal glucose metabolism -0.08 [-0.17, 0.03], type 2 diabetes vs normal glucose metabolism -0.14 [-0.25, -0.04]; linear trend analysis showed a p value of 0.001), and higher levels of measures of glycaemia (fasting plasma glucose, 2 h post-load glucose, HbA 1c , SAF and duration of diabetes) were all significantly associated with a lower composite Z-score for corneal nerve fibre measures (per SD: -0.09 [-0.13, -0.05], -0.07 [-0.11, -0.03], -0.08 [-0.11, -0.04], -0.05 [-0.08, -0.01], -0.09 [-0.17, -0.001], respectively). In general, directionally similar associations were observed for individual corneal nerve fibre measures., Conclusions/interpretation: To our knowledge, this is the first population-based study to show that a more adverse glucose metabolism status and higher levels of glycaemic measures were all linearly associated with corneal neurodegeneration after adjustment for an extensive set of potential confounders. Our results indicate that glycaemia-associated corneal neurodegeneration is a continuous process that starts before the onset of type 2 diabetes. Further research is needed to investigate whether early reduction of hyperglycaemia can prevent corneal neurodegeneration., (© 2023. The Author(s).)
