Formula feeding is associated with increased hospital admissions due to infections among infants younger than 6 months in Manila, Philippines.

This case control study evaluates the association between hospitalization due to infection and feeding practices among infants aged >or= 3 days to < 6 months. Mothers of 191 cases hospitalized for infections and 208 healthy controls were interviewed using a standardized questionnaire documenting infant-feeding history. Results given in odds ratio and 95% confidence intervals (OR, 95% CI) were adjusted for age, education, and place of delivery. Exclusively formula-fed infants were more likely to be hospitalized for any infection (3.7, 1.8-7.5), pneumonia (3.0, 1.2-7.4), and diarrhea (10.5, 2.5-41.9) compared to exclusively breastfed infants. Infants who did not receive any breast milk were more likely to be hospitalized for any infection (3.5, 2.1-5.9), neonatal sepsis (4.9, 1.3-18.3), pneumonia (2.8, 1.5-5.4), and diarrhea (19.6, 6.5-58.6) than infants who received any breast milk. This study showed a strong positive association between the intake of formula and/or nonbreast milk supplements and the risk of hospitalization for infectious causes.

Association between intestinal tight junction permeability and whole-body electrical resistance in healthy individuals: a hypothesis.

OBJECTIVE: Intestinal permeability describes non-carrier-mediated modes of transport through the intestinal epithelium. Wrist-ankle bioimpedance analysis (BIA) is a standard method to determine body composition based on the measurements of whole-body electrical resistance and reactance values. The present report deals with the coincidentally observed associations between permeability results and electrical raw values of BIA and their subsequent reproduction in a larger group of individuals. METHODS: Tetrapolar wrist-ankle BIA was performed on day 1 in the initial sample (12 women, 36 +/- 11 y of age) and the validation sample (36 healthy subjects, 26 women and 10 men, 35 +/- 14 y of age). Intestinal permeability tests (lactulose and mannitol) were implemented within 1 wk thereafter. Wrist-ankle electrical resistance plus electrical resistance between current-conducting electrodes and voltage-sensing electrodes (Rtotal) was measured at 5 kHz and 100 kHz. RESULTS: Permeability and bioimpedance raw values were normal, indicating normal tight junction permeability and normal hydration. Lactulose correlated to R(50total) in the initial sample (rho = 0.639, P = 0.025) and in the validation sample (rho = 0.673, P < 0.001). Weaker associations to R(50total) were observed with mannitol (rho = 0.381, P = 0.008) and lactulose/mannitol (rho = 0.369, P = 0.010) in the total group of individuals. Regression analyses demonstrated that R(50total) alone accounted for 41.3% of the variance in lactulose permeability. CONCLUSION: The nature of the observed positive association between intestinal tight junction permeability and whole-body electrical resistance is unclear. We hypothesize that regulation involving submolecular mechanisms based on the principles of quantum physics might have caused the observed association. Such coherent mechanisms might possibly play a role in basal physiologic regulation in humans.

Circulating adipokines and the protective effects of hyperinsulinemia in inflammatory bowel disease.

OBJECTIVE: Adipokines are fat-derived hormones and cytokines with immune-modulating and metabolic properties. Most of them are associated with insulin resistance. The aim of the present investigation was to evaluate circulating levels of adipokines and glucose homeostasis in patients with inflammatory bowel disease (IBD) and to evaluate possible associations with the course and characteristics of the disease. METHODS: Serum leptin, resistin, visfatin, retinol-binding protein-4, adiponectin, glucose, insulin, and inflammatory parameters were analyzed in 93 patients with inactive IBD (49 with Crohn's disease [CD], 44 with ulcerative colitis [UC]), 35 patients with active IBD (18 with CD, 17 with UC), and 37 age- and body mass index-matched healthy controls. Ninety-two patients were followed for 6 mo. RESULTS: Leptin was similar in patients with IBD and controls, whereas resistin and visfatin were increased in patients with active disease but not in those in remission. In active and inactive disease, adiponectin was decreased (P < 0.001) and retinol-binding protein-4 was increased (P < 0.001) compared with controls. About 60% of patients with IBD showed increased levels of insulin, whereas serum glucose remained normal, resulting in increased homeostasis model assessment values in most patients. Hyperinsulinemia was associated with the decrease in adiponectin (r = -0.572, P < 0.001) and proved to be an independent protective factor for 6-mo maintenance of remission (P = 0.016). CONCLUSION: IBD led to largely similar alterations in circulating adipokines and hyperinsulinemia in patients with CD and those with UC. The unexpected protective effect of hyperinsulinemia on relapse rate denotes the role of the metabolic-inflammatory response as a modulator in IBD.

Malnutrition and impaired muscle strength in patients with Crohn's disease and ulcerative colitis in remission.

OBJECTIVE: This prospective, controlled, and multicentric study evaluated nutritional status, body composition, muscle strength, and quality of life in patients with inflammatory bowel disease in clinical remission. In addition, possible effects of gender, malnutrition, inflammation, and previous prednisolone therapy were investigated. METHODS: Nutritional status (subjective global assessment [SGA], body mass index, albumin, trace elements), body composition (bioelectrical impedance analysis, anthropometry), handgrip strength, and quality of life were assessed in 94 patients with Crohn's disease (CD; 61 female and 33 male, Crohn's Disease Activity Index 71 +/- 47), 50 patients with ulcerative colitis (UC; 33 female and 17 male, Ulcerative Colitis Activity Index 3.1 +/- 1.5), and 61 healthy control subjects (41 female and 20 male) from centers in Berlin, Vienna, and Bari. For further analysis of body composition, 47 well-nourished patients with inflammatory bowel disease were pair-matched by body mass index, sex, and age to healthy controls. Data are presented as median (25th-75th percentile). RESULTS: Most patients with inflammatory bowel disease (74%) were well nourished according to the SGA, body mass index, and serum albumin. However, body composition analysis demonstrated a decrease in body cell mass (BCM) in patients with CD (23.1 kg, 20.8-28.7, P = 0.021) and UC (22.6 kg, 21.0-28.0, P = 0.041) compared with controls (25.0 kg, 22.0-32.5). Handgrip strength correlated with BCM (r = 0.703, P = 0.001) and was decreased in patients with CD (32.8 kg, 26.0-41.1, P = 0.005) and UC (31.0 kg, 27.3-37.8, P = 0.001) compared with controls (36.0 kg, 31.0-52.0). The alterations were seen even in patients classified as well nourished. BCM was lower in patients with moderately increased serum C-reactive protein levels compared with patients with normal levels. CONCLUSION: In CD and UC, selected micronutrient deficits and loss of BCM and muscle strength are frequent in remission and cannot be detected by standard malnutrition screening.

Altered status of antioxidant vitamins and fatty acids in patients with inactive inflammatory bowel disease.

BACKGROUND & AIMS: Data regarding the nutritional status, antioxidant compounds and plasma fatty acid (FA) composition in inactive IBD are conflicting. We compared plasma levels of antioxidants and FA of patients with inactive IBD with active IBD and controls. METHODS: Plasma levels of vitamin C, vitamin E, carotenoids, saturated, monounsaturated and polyunsaturated FA, inflammatory markers and nutritional status were determined after an overnight fast in 132 patients with quiescent IBD (40.6+/-13.2 years, 87F/45M), 35 patients with active disease (37.9+/-12.1 years, 25F/10M) and 45 age- and BMI-matched healthy controls (38.1+/-10.5 years, 39F/6M). Results are expressed as mean+/-SD or median [25th percentile;75th percentile]. RESULTS: Body mass index (BMI) was normal in inactive (23.9+/-4.7 kg/m(2)), active IBD (22.7+/-4.2 kg/m(2)) and controls (22.3+/-1.9 kg/m(2)). Compared with controls patients with quiescent IBD showed significantly decreased plasma levels of carotenoids (1.85 [1.37;2.56] vs 1.39 [0.88;1.87] micromol/L) and vitamin C (62.3 [48.7;75.0] vs 51.0 [36.4;77.6] micromol/L), increased levels of saturated FA (3879 [3380;4420] vs 3410 [3142;3989] micromol/L) and monounsaturated FA (2578 [2258;3089] vs 2044 [1836;2434] micromol/L) and similar levels of vitamin E and polyunsaturated FA. Results in active disease were similar to inactive disease. CONCLUSION: This study shows that antioxidant status and FA profile in a larger population of IBD patients are disturbed independently from disease activity and despite normal overall nutritional status.

Nutrition status and pressure ulcer: what we need for nutrition screening.

BACKGROUND: Pressure ulcers (PU) and malnutrition exist in elderly hospitalized patients as a significant and costly problem. The aim of the study was to compare different screening tools to assess nutrition status and to verify them for usage in clinical routine. METHODS: Nutrition status (body mass index [BMI], Mini Nutritional Assessment [MNA], weight loss) was determined in 484 (326 female/158 male) multimorbid elderly patients with mean age of 79.6 +/- 7.6 (80.9 +/- 7.4 female/76.9 +/- 7.4 male) years. Bioelectrical impedance analysis (BIA; Nutrigard 2,000-M) was used for evaluation of body composition. Activities of daily living (ADL) were measured with the Barthel Index. PUs were divided into stages I-IV (European Pressure Ulcer Advisory Panel [EPUAP]) and were assessed by the Norton scale. RESULTS: The prevalence of PU was 16.7%, with a median Norton scale of 20 (range, 17-24). According to MNA, 39.5% of the PU patients were malnourished, and 2.5% were well nourished. By contrast, 16.6% of the non-PU patients were malnourished, and 23.6% were well nourished. BMI decreased significantly in PU patients (p < .008). BIA resulted in no significant resistance and reactance but in a significant reduction of phase angle in PU. According to a significantly reduced body cell mass and lean body mass in PU patients, the ADL decreased in these patients, too. Furthermore, we analyzed a significant effect of age, ADL, MNA, BMI, phase angle, and body cell mass on the Norton scale. CONCLUSIONS: The MNA as a screening and assessment tool is easy to use to determine the nutrition status in multimorbid geriatric patients with PU. Further studies are needed to show an improved outcome of PU healing if evaluation of nutrition status is part of routine clinical practice in multimorbid elderly risk patients within the first day after admission.
