Se ha comparado la absorcion de grasa total, da acido grasos y la absorcion y retencion de calcio, magnesio y fosfato en dos grupos de nnos alimentados con una formula sin lactosa (FSL) frente a otra de inicio convencional identica (FI). Ningunas de ellas estaba adicionada de acido araquidonico ni docosahexaenoico. Conclusion: el patron absortivo de los acidos grasos en el recien nacido a termino no presenta anomalias ni disminuciones llamativas.

The transition temperatures of DMPC, DPPC and DSPC are near to the observed for the microsomal fraction. So that, thyroid peroxidase (TPO) was incorporated into liposomes made with these phospholipids. 3. When DPH was incorporated in this peroxidase-liposome complex, a less pronounced phase transition was observed in the profiles of temperature dependence of DPH polarization, and the incorporation of the enzyme decreased the Tc. 4. Arrhenius plots of TPO incorporated into liposomes showed discontinuities at similar temperatures observed by fluorescence polarization. 5. The decrease of transition temperature of liposomes induced by thyroid peroxidase incorporation suggests that this enzyme seems to need a fluid medium for its enzyme activity.

To explore anthropometric changes in normal-weight, overweight and obese subjects who did not dropout or fail a weight loss program over the 16 treatment weeks to improve patient motivation and treatment adherence. Methods. A clinical intervention study was conducted among 271 (including 100 dropouts and/or failures) obese and overweight patients who consulted a nutrition clinic in Barranquilla (Colombia) for the purpose of nutritional assessment. They were subject to a personalized weekly follow-up consultation over the course of 16 weeks in which initial and the final Body Mass Index (BMI, kg/m 2), photographs, food consumption patterns, percentage weight loss, waist and hip circumference were registered and grouped according to BMI, measuring treatment response. Data's nonparametric statistical comparison was made. Results. In 62 patients from the BMI < 25 group, there is weight loss of 2.6% (3.1 SD), 5.5% (3.3 SD) in waist circumference and 3.0% (2.5 SD) in hip circumference. In 67 patients from the 25 ≥ BMI < 30 group, there is weight loss of 3.8% (4.1 SD), 5.7% (4.5 SD) in waist circumference loss and 3.7% (3.0 SD) in hip circumference loss. In 42 patients from the BMI > 30 group, there is weight loss of 4.8% (3.7 SD), 7.0% (3.6 SD) in waist circumference loss and 3.9% (2.4 SD) in hip circumference loss. Monitoring is done every 4 weeks by the Friedman test, with significant differences between the three groups (p < 0.001). Patients do not drop out of treatment because they start to see physical results in waist decrease. When comparing final values of initial waist/hip circumference ratios and waist/height ratios, a clear decrease in the three BMI groups was observed (p < 0.001). Conclusion. After three weeks of continuous treatment patients improved in all overweight and obesity parameter indicators; there were not statistically significant differences in hip circumference (HC) and waist loss (WC) (%) among the three BMI groups (normal-weight, overweight, and obesity). In contrast, there were statistically significant differences in weight loss (%) and waist-to-hip ratios. Based on anthropometric outcomes and patient perception of their body image it can be concluded that the waist circumference loss is the parameter that retains obese patients in the weight loss program.

The authors briefly describe those diseases which are subject to neonatal screening with the objective of providing their basic features, especially in relation to neonatal screening and the benefits which this may provide. The authors explain the method to correctly take a blood sample on the paper filter sample cards and they describe the most frequently committed errors as a way to prepare nursing personnel which may at some time have contact with these functions so that these are properly performed.

Methods A two-phase non-interventional, observational, prospective pilot study was performed to evaluate safety and efficacy of FCM given immediately after IFX. IBD patients were re-cruited consecutively in the outpatient clinic in two groups. Control group patients (n = 12) received FCM on a separate day from IFX. Subsequently, single-session group patients (n = 33) received FCM after IFX on the same day. All patients received 5mg/kg IFX and 1000mg FCM for iron-restricted anemia (IRA) or 500mg FCM for iron deficiency without anemia. Safety assessment was performed by recording adverse events (AEs) during and immediately after infusion, 30 minutes afterwards, and via follow-up at 7 days and 8 weeks. For efficacy assessment, hematological parameters were assessed prior to ...

Analytical recovery is estimated by use of added 3H-labeled vitamin D. For repeated assays of a reconstituted proprietary powdered milk formula in two runs, the intra-assay vitamin D values were 9.0 (SD 1.4) (n = 6) and 8.9 (SD 1.6) micrograms/L (n = 7) (t = 0.07). Assay of a proprietary liquid formula yielded values of 14.9 (SD 0.9) micrograms/L (n = 6). For each, the results agreed with the vitamin D content shown on the label. Vitamin D concentrations in breast milk from two groups of lactating mothers of different social class and nutritional status were 2.3 (SD 1.4) (n = 7) and 2.0 (SD 1.7) micrograms/L (n = 7). Overall recoveries ranged from 65 to 75%. Only 2 mL of milk is required, which facilitates samp...

However, this study did not include inferential statistics. The aims of the present study were to update the literature search and calculate confidence intervals for the prevalence of each phenotype using bootstrap methodology. Published case reports of patients with the syndrome that included detailed information about breakpoints and phenotype were sought and 36 were included. Deletions in megabase (Mb) pairs were determined to calculate the size of the interstitial deletion of the phenotypes studied in 2012. To determine confidence intervals for the prevalence of the phenotype and the interstitial loss, we used bootstrap methodology. Using the bootstrap percentiles method, we found wide variability in the prevalence of the different phenotypes (3–100%). The mean interstitial deletion size was 2.72 Mb (95% CI [2.35–3.10 Mb]). In comparison with our work, which expanded the literature s...

We developed a tool to evaluate malnutrition risk that can be completed more rapidly using just clinical variables. Between 2008 and 2013, we conducted a cross-sectional study of 418 women aged ≥60 years from Mexico. Our outcome was positive MNA and our secondary variables included were: physical activity, diabetes mellitus, hypertension, educational level, dentition, psychological problems, living arrangements, history of falls, age and the number of tablets taken daily. The sample was divided randomly into two groups: construction and validation. Construction: a risk table was constructed to estimate the likelihood of the outcome, and risk groups were formed. Validation: the area under the ROC curve (AUC) was calculated and we compared ...

AA was not decreased. Vitamin D content was low despite mothers were living in a sunny and temperate area. The content of 25 hydroxyvitamin D is increased in the group on fish intake, probably pointing out its marine source.

Material and methods: The study was carried out to 184 students of both sexes (96 of Human Nutrition and Dietetics and Nursing 88) of the University of Alicante. Were weighed and carved to calculate BMI; food consumption was estimated by the reminder of 24 hours; intake of macro and micronutrients were calculated using the program Easydiet. Comparing the results obtained in both qualifications and according to nutritional status by performing the corresponding statistical analysis. Results: The majority of the students analyzed are normal weight (80%). There were significant differences in the quality of the diet both degrees, being the same characteristics: low in carbohydrates and high in protein. It also shows an imbalance in the type of fat consumed, with a higher consumption of saturated and less from polyunsaturated than recommended. Likewise, analyzed that nutrition students do more exercise than the nurses, although they sleep fewer hours and spend more time in front of the computer and TV. Conclusion: While the levels of overweight and obesity among students is less than that of the general population, there are imbalances in your diet, noting that consumption of macronutrients is located away from the recommendations, and that there are deficiencies in the intake of micronutrients. Showing that have knowledge of nutrition, does not affect healthy decision-making to a diet and lifestyle.

Therefore, no paper has compared the clinical inertia rates between morbidly and nonmorbidly obese patients. A cross-sectional observational study was carried out. We analysed 8687 obese patients ⩾40 years of age who attended their health-care center for a checkup as part of a preventive program. The outcome was morbid obesity. Secondary variables were as follows: failure in the management of high blood pressure (HBP), high blood cholesterol (HBC) and high fasting blood glucose (HFBG); gender; personal history of hypertension, dyslipidemia, diabetes, smoking and cardiovascular disease; and age (years). We analysed the association between failures and morbid obesity by calculating the adjusted odds ratio (OR). Of 8687 obese patients, 421 had morbid obesity (4.8%, 95% confidence interval (CI): 4.4-5.3%). The prevalence rates for failures were as follows: HBP, 34.7%; HBC, 35.2%; and HFBG, 12.4%.

Its presence in high concentrations is a risk factor for health, being involved in a series of events, cardiovascular, inflammatory, etc. Therefore, steps have been taken for its decrease in the diet. The aim is to determine serum and phospholipids of membranes in healthy children and neurological alterations. It has analyzed the fatty acids trans in 34 healthy children and 374 with various neurological pathologies. Serum and blood cells, making the lipid extraction, samples have been separation of the phospholipids of cells membranes, methylation of fatty acids, separation by gas chromatography and quantification using mass detector. The data have been processed statistically. The distribution of trans fatty acids and their sum is not normally distributed, so its nonparemetric tests were used. The values are higher than in serum phospholipids and membrane with a weak but significant correla...

If not absorbed, calcium soaps can be produced with the intestinal fatty acids. Absorption and retention of total fat, individual fatty acids, calcium, magnesium and phosphate have been compared between two groups of children, one fed with lactose free formula and higher levels of calcium (FSL) and the other with standard starting formula (FI). None of them had additional arachidonic or docosahexaenoic acids. A randomized prospective study was made on 19 term newborn babies by means of metabolic balance measurement during an 8 day period (four days of a stabilization period on the formula, 3 days of the balance period and the final day for feces collection). Both groups were selected following the same criteria for gestational age, balance age, and weight and length at both time periods. Aliquos from the formula were collected daily, as well as all feces and urine during the balance period. Calcium and magnesium quantificatio...
