Increasing Intake (increasing + intake)
Selected AbstractsSodium intake and intraventricular hemorrhage in the preterm infantANNALS OF NEUROLOGY, Issue 6 2010Alan R. Barnette MD Objective Hypernatremia is associated with intracranial hemorrhage in term infants. The etiology of intraventricular hemorrhage in preterm infants is multifactorial. We aimed to characterize the associations between sodium intake, hypernatremia, and intraventricular hemorrhage in preterm infants. Methods The charts of 722 preterm infants with a birth weight ,1.5kg admitted to a tertiary care neonatal intensive care unit from 2002 to 2006 were retrospectively reviewed for daily sodium and fluid intake, weight loss, serum sodium concentrations, gender, gestational age, pneumothorax, hyper- or hypocarbia, severity of illness, and cranial imaging. A multivariate logistic model was used to adjust for risk factors and determine associations between sodium intake, hypernatremia, and intraventricular hemorrhage. Results Grade II to IV intraventricular hemorrhage was associated with increased sodium intake on each of the first 3 days following birth. The association remained after controlling for gestational age, severity of illness, respiratory factors, and gender. The association of high sodium intake with intraventricular hemorrhage was of similar magnitude to traditionally recognized risk factors such as pneumothorax. Interpretation Increasing intake of sodium appears to be a modifiable risk factor for intraventricular hemorrhage in very low birth weight infants.

Most of these conditions, however, do not progress to breast cancer. The purpose of our study was to identify factors possibly associated with this progression. Women with proliferative fibrocystic breast conditions alone (214), and women with proliferative fibrocystic breast conditions and concurrent breast cancer (130), were compared to each other, and each of these groups of women were also compared to 1,070 controls; and 176 women with non-proliferative benign breast conditions alone, and 155 also with breast cancer, were similarly compared. All study subjects were selected from a cohort of women enrolled in a trial of breast self-examination in Shanghai. Women were interviewed to ascertain information on suspected risk factors for breast cancer and dietary habits. Conditional logistic regression was used to estimate adjusted odds ratios (OR) and 95% confidence intervals (CI). Increased risks of both proliferative fibrocystic breast conditions alone, and with breast cancer, were associated with low parity, a prior benign breast lump and breast cancer in a first-degree relative. Decreasing trends in the risk of both conditions with increasing intake of fruits and vegetables were observed. No factors were significantly associated with risk of breast cancer relative to risk of proliferative changes. Similar, but in some instances weaker, associations were observed for non-proliferative fibrocystic conditions with and without breast cancer. The possible risk or protective factors that were observed in our study most likely alter the risk of breast cancer at an early stage in the carcinogenic process, and probably do not alter risk of progression from proliferative fibrocystic breast conditions to breast cancer. © 2005 Wiley-Liss, Inc. [source] Carotenoids/vitamin C and smoking-related bladder cancerINTERNATIONAL JOURNAL OF CANCER, Issue 3 2004J. Esteban Castelao Abstract Previous epidemiological studies of fruit and vegetable intake and bladder cancer risk have yielded inconsistent results, especially with respect to the role of cigarette smoking as a possible modifier of the diet-bladder cancer association. A population-based case-control study was conducted in nonAsians of Los Angeles, California, which included 1,592 bladder cancer patients and an equal number of neighborhood controls matched to the index cases by sex, date of birth (within 5 years) and race between January 1, 1987 and April 30, 1996. Information on smoking, medical and medication history, and intake frequencies of food groups rich in preformed nitrosamines, vitamins A and C and various carotenoids, were collected through in-person, structured interviews. Beginning in January 1992, all case patients and their matched control subjects were asked for a blood sample donation at the end of the in-person interviews for measurements of 3- and 4-aminobiphenyl (ABP) hemoglobin adducts, and glutathione S -transferases M1/T1/P1 (GSTM1/T1/P1) and N -acetyltransferase-1 (NAT1) genotypes. Seven hundred seventy-one (74%) case patients and 775 (79%) control subjects consented to the blood donation requests. In addition, all case patients and matched control subjects were asked to donate an overnight urine specimen following caffeine consumption for measurements of cytochrome P4501A2 (CYP1A2) and N -acetyltransferase-2 (NAT2) phenotypes. Urine specimens were collected from 724 (69%) case patients and 689 (70%) control subjects. After adjustment for nondietary risk factors including cigarette smoking, there were strong inverse associations between bladder cancer risk and intake of dark-green vegetables [p value for linear trend (p) = 0.01], yellow-orange vegetables (p = 0.01), citrus fruits/juices (p = 0.002) and tomato products (p = 0.03). In terms of nutrients, bladder cancer risk was inversely associated with intake of both total carotenoids (p = 0.004) and vitamin C (p = 0.02). There was a close correlation (r = 0.58, p = 0.0001) between intakes of total carotenoids and vitamin C in study subjects. When both nutrients were included in a multivariate logistic regression model, only total carotenoids exhibited a residual effect that was of borderline statistical significance (p = 0.07 and p = 0.40 for total carotenoids and vitamin C, respectively). Cigarette smoking was a strong modifier of the observed dietary effects; these protective effects were confined largely to ever smokers and were stronger in current than ex-smokers. Smokers showed a statistically significant or borderline statistically significant decrease in 3- and 4-aminobiphenyl (ABP)-hemoglobin adduct level with increasing intake of carotenoids (p = 0.04 and 0.05, respectively). The protective effect of carotenoids on bladder cancer seemed to be influenced by NAT1 genotype, NAT2 phenotype and CYP1A2 phenotype; the association was mainly confined to subjects possessing the putative NAT1 -rapid, NAT2-rapid and CYP1A2-rapid genotype/phenotype. The carotenoid-bladder cancer association was not affected by the GSTM1, GSTT1 and GSTP1 genotypes. © 2004 Wiley-Liss, Inc. [source] Dietetic guidelines on food and nutrition in the secondary prevention of cardiovascular disease , evidence from systematic reviews of randomized controlled trials (second update, January 2006)JOURNAL OF HUMAN NUTRITION & DIETETICS, Issue 6 2006A. Mead Abstract Aim, To update dietetic guidelines based on systematic review evidence on dietary advice to prevent further events in people with existing cardiovascular disease (CVD) (secondary prevention). Methods, The Cochrane Library, MEDLINE and EMBASE were comprehensively searched to January 2005 for systematic reviews on aspects of diet and heart health. Reviews were included if they searched systematically for randomized controlled trials relating to diet and secondary prevention of CVD. Each review was critically appraised by at least two members of the UK Heart Health and Thoracic Dietitians Group. The quality and results of each review were discussed and summarized at a group meeting. Results, Evidence-based strategies that reduce cardiovascular events in those with CVD include reduction in saturated fat and substitution with unsaturated fats. Individuals who have suffered a myocardial infarction may also benefit from adopting a Mediterranean type diet and increasing intake of omega 3 fats, but it is not clear whether they are beneficial for all patients with CVD. There is no systematic review evidence to support the use of antioxidant vitamins supplements, low glycaemic index diets, or homocysteine lowering therapies in this group. Conclusion, There remains good evidence that reducing saturated fat reduces morbidity in patients with CVD. This advice is consistent for most manifestations of CVD, with the addition of Mediterranean dietary advice and increased omega 3 fats for those who have had a myocardial infarction.

The association of Crohn's disease with westernization has implicated lifestyle factors in pathogenesis. While diet is a likely candidate, evidence for specific changes in dietary habits and/or intake has been lacking. A new hypothesis is proposed, by which excessive delivery of highly fermentable but poorly absorbed short-chain carbohydrates and polyols (designated FODMAPs , Fermentable Oligo-, Di- and Mono-saccharides And Polyols) to the distal small intestinal and colonic lumen is a dietary factor underlying susceptibility to Crohn's disease. The subsequent rapid fermentation of FODMAPs in the distal small and proximal large intestine induces conditions in the bowel that lead to increased intestinal permeability, a predisposing factor to the development of Crohn's disease. Evidence supporting this hypothesis includes the increasing intake of FODMAPs in western societies, the association of increased intake of sugars in the development of Crohn's disease, and the previously documented effects of the ingestion of excessive FODMAPs on the bowel. This hypothesis provides potential for the design of preventive strategies and raises concern about current enthusiasm for putative health-promoting effects of FODMAPs. One of the greatest challenges in defining the pathogenesis of Crohn's disease is to identify predisposing environmental factors. Such an achievement might lead to the development of preventive strategies for, and the definition of, possible target for changing the natural history of this serious disease. The present paper describes a new hypothesis for one such environmental factor. [source] The grain, the wholegrain and nothing but the grain: the science behind wholegrain and the reduced risk of heart disease and cancerNUTRITION BULLETIN, Issue 4 2000David P. Richardson Summary Wholegrain foods are important sources of nutrients and phytoprotective substances that are in short supply in our diet. Encouraging the public to increase consumption of wholegrain foods imparts a positive health message and could contribute towards the achievement of reduced fat and increased fibre intakes. More recent research suggests that the health benefits of wholegrain foods are derived from more than just the fibre. Wholefoods, such as fruit and vegetables and wholegrains, deliver ,packages' of constituents that may work synergistically to promote health. Wholegrain foods, particularly cereals, have been shown to be protective against coronary heart disease, certain cancers and diabetes. At least one daily serving of wholegrain food is associated with reduced risk of disease and there may be further benefits with increasing intake. A greater consumption of wholegrain foods has important public health implications, and would be an attractive and prudent food-based dietary strategy, targeted at the whole population.
