A mid-morning snack of almonds generates satiety and appropriate adjustment of subsequent food intake in healthy women.

PURPOSE: To assess the effect of consuming a mid-morning almond snack (28 and 42 g) tested against a negative control of no almonds on acute satiety responses. METHOD: On three test days, 32 healthy females consumed a standard breakfast followed by 0, 28 or 42 g of almonds as a mid-morning snack and then ad libitum meals at lunch and dinner. The effect of the almond snacks on satiety was assessed by measuring energy intake (kcal) at the two ad libitum meals and subjective appetite ratings (visual analogue scales) throughout the test days. RESULTS: Intake at lunch and dinner significantly decreased in a dose-dependent manner in response to the almond snacks. Overall, a similar amount of energy was consumed on all three test days indicating that participants compensated for the 173 and 259 kcals consumed as almonds on the 28 and 42 g test days, respectively. Subjective appetite ratings in the interval between the mid-morning snack and lunch were consistent with dose-dependent enhanced satiety following the almond snacks. However, in the interval between lunch and dinner, appetite ratings were not dependent on the mid-morning snack. CONCLUSION: Almonds might be a healthy snack option since their acute satiating effects are likely to result in no net increase in energy consumed over a day.

GutSelf: Interindividual Variability in the Processing of Dietary Compounds by the Human Gastrointestinal Tract.

Nutritional research is currently entering the field of personalized nutrition, to a large extent driven by major technological breakthroughs in analytical sciences and biocomputing. An efficient launching of the personalized approach depends on the ability of researchers to comprehensively monitor and characterize interindividual variability in the activity of the human gastrointestinal tract. This information is currently not available in such a form. This review therefore aims at identifying and discussing published data, providing evidence on interindividual variability in the processing of the major nutrients, i.e., protein, fat, carbohydrates, vitamins, and minerals, along the gastrointestinal tract, including oral processing, intestinal digestion, and absorption. Although interindividual variability is not a primary endpoint of most studies identified, a significant number of publications provides a wealth of information on this topic for each category of nutrients. This knowledge remains fragmented, however, and understanding the clinical relevance of most of the interindividual responses to food ingestion described in this review remains unclear. In that regard, this review has identified a gap and sets the base for future research addressing the issue of the interindividual variability in the response of the human organism to the ingestion of foods.

[The application of the SCORE charts to advanced age males triple the number of high-risk subjects compared to the Framingham function]. / La aplicación de las tablas del SCORE a varones de edad avanzada triplica el número de sujetos clasificados de alto riesgo en comparación con la función de Framingham.

BACKGROUND AND OBJECTIVE: The Framingham function, recommended by the National Cholesterol Education Program in its document Adult Treatment Panel III (ATP III), and the risk charts of the Systematic Coronary Risk Evaluation (SCORE) program are the most used functions for risk stratification. In both, intensive hygienic and therapeutic measures are recommended for high risk individuals. The objective of the present study was to compare the risk stratification obtained with both functions in a population of subjects older than 60 years. SUBJECTS AND METHOD: 1001 non-diabetic subjects between 60 and 79 years old (mean: 69 years, 67% female) with no evidence of cardiovascular disease were included in the study. Participants were classified as low, moderate or high risk by ATP-III (< 10%, 10-20% y > 20% of risk at 10 years, respectively) and by SCORE (< 3%, 3-4% y > or = 5% of risk at 10 years respectively). RESULTS: 11.7% of the population was classified as high risk by Framingham and 17.6% by SCORE. Only 5% of the females were classified as high risk with either function. In males, 16.7% and a 44.4% were classified as high risk by Framingham and SCORE respectively. The results did not differ by age group. A 39% of males and a 20% of females were candidates to hypolipidemic treatment as recommended by SCORE guidelines. CONCLUSIONS: Compared to Framingham function, the application of SCORE charts to spanish males over 60 years triplicate the number of high risk individuals and candidates to intensive risk factor treatment.

[Incidence, risk factors and influence on survival of infectious complications in liver transplantation]. / Incidencia, factores de riesgo e influencia sobre la supervivencia de las complicaciones infecciosas en el trasplante hepático.

INTRODUCTION: Orthotopic liver transplantation (OLT) is successful therapy for patients with end-stage liver disease. Infection is currently a life-threatening complication for these patients. The aims of this study are to determine the incidence of various infections in patients with OLT, to study overall survival rates and survival as related to individual infections, and to investigate the risk factors associated with first episodes of bacterial (BI), fungal (FI), invasive fungal (IFI) and cytomegalovirus (CMV) infections. METHODS: The study includes 165 OLTs performed in 152 recipients from May 1994 to May 1998. A descriptive analysis estimating the 95% confidence interval was performed with 100 variables stratified according to preoperative, operative and postoperative conditions. Cox regression analysis was used to identify the variables associated with infection. Survival studies were carried out with the Kaplan-Meier method. RESULTS: Among the total, 66% of patients developed infection: 41.8% viral, 33.9% BI, 20.6% FI and 4.2% IFI. One-year and 4-year survival rates after transplantation were 90% and 75%, respectively. All the infections decreased survival. Multivariate analyses identified the following risk factors for the specific infections: BI - dialysis, mechanical ventilation, and time of organ ischemia during harvesting; FI - number of hours of surgery and pretransplantation plasma albumin concentrations; IFI - number of blood units transfused, pretransplantation plasma albumin and retransplantation. Cytomegalovirus infection was associated with FI and IFI in the univariate analysis, but the multivariate analysis identified no variables that independently increased the risk of developing this infection.
