Evaluation of the Oxidative Status of Salami Packaged with an Active Whey Protein Film.

Active packaging aims to prolong food's shelf-life by directly interacting with the packaged food. This type of packaging is characterized by having the active agent incorporated into the package polymer, such as antioxidant additives, that will gradually migrate from the package polymer to the packed food and, consequently, delay food's natural lipid oxidation. In this study, the efficiency of an active whey protein film incorporated with a rosemary extract on retarding the lipid oxidation of salami slices was evaluated. The lipid oxidation of the salami was measured by the thiobarbituric acid reactive substances (TBARS) assay and hexanal monitorization. Also, a sensory analysis on the salami packaged for 60 and 90 days was performed. The active film was able to delay the salami's lipid oxidation for, at least, 30 days. The samples packaged with the active film revealed a bitter taste related to the rosemary extract and a bit sweet from the WP and the glycerol.

Abstract Background: The transition to higher education is a period of change during which students have new experiences that influence their lifestyles. Objective: To identify the domains of higher education students' lifestyles that require intervention. Methodology: This cross-sectional descriptive correlational study was conducted with 522 higher education students. The Fantastic Lifestyle Assessment questionnaire was used, and statistical analysis was conducted using the IBM SPSS Statistics software - version 25.0. Results: The study participants had a median age of 22, and 78.4% were women. Of the 522 students in the sample, 17.8% were overweight and 6.3% were obese, 14.4% were diagnosed with a chronic disease, 35.6% had Very Good lifestyles, and 20.1% had Good lifestyles. The domains Health and sexual behavior (x-= 8.97/24) and Work/type of personality (x-= 6.82/12) obtained negative scores. Significant differences were found in the questionnaire's total score (U =19785.00; p < 0.05) when considering the variables Gender, with female students having better lifestyles (x-= 89.16; SD = 12.75) and Course year (H = 18.80; p < 0.01). Conclusion: Assessing higher education students' lifestyles offers the possibility to describe the intervention foci and guide the health promotion interventions.

A functional Roux-en-Y gastric bypass to avoid gastric exclusion: 1-year results.

BACKGROUND: Roux-en-Y gastric bypass (RYGBP) is rarely performed in Italy because it involves gastric exclusion. RYGBP with the stomach partitioned by an adjustable gastric band has been previously described. We have developed a functional RYGBP (FRYGBP) where an adjustable band allows access from a stapled gastric bypass pouch into the distal stomach. METHODS: From October 2001 to May 2002, 16 patients underwent FRYGBP. A 30-cc vertical gastric pouch was fashioned by a 25-mm circular and 90-mm four-row stapler as in the Mason VBG. A hand-sewn retrocolic gastroenterostomy with 150-cm Roux and 30-cm afferent limbs completed the operation. The pouch outlet was encircled distal to the gastrojejunostomy by a non-inflated adjustable gastric band. The bands were inflated at 1 month during barium swallow, to demonstrate occlusion of the gastro-gastric outlet and patency of the gastrojejunostomy. RESULTS: There was no operative mortality. After 1 year, mean percent excess BMI loss (%EBMIL) was 71.2 +/- 16.2% (SD), and gastroscopy of the bypassed stomach was possible on 81% of the patients. There were three asymptomatic late complications (19%): two band erosions, converted to RYGBP, and one stenosis of the gastro-gastric outlet. CONCLUSION: FRYGBP thus far has been effective and allows the study of the excluded stomach. This ongoing study will undergo long-term evaluation.

Pharmacodynamics of low molecular weight heparin in patients undergoing bariatric surgery: a prospective, randomised study comparing two doses of parnaparin (BAFLUX study).

BACKGROUND: The optimal dose of low-molecular-weight-heparin (LMWH) to prevent venous thromboembolism (VTE) after bariatric surgery remains controversial. AIM: The aim of this study was to evaluate the pharmacodynamic parameters of two doses of the LMWH parnaparin administered to patients undergoing bariatric surgery. METHODS: Patients were enrolled in a multicentre, open label, pilot study and were randomised to receive 4250 IU/day [n=36; 30 females; median age: 38 years (23-56); median BMI: 46.7 Kg/m(2) (36.5-58.8)] or 6400 IU/day [n=30; 24 females; median age: 42 years (22-63); median BMI: 43.7 Kg/m(2) (36.1-64.1)] of parnaparin s.c. for 7-11 days. The pharmacodynamic effects of parnaparin were analysed by measuring the anti Factor Xa activity on day 0 (12 hours after the first parnaparin injection), day 4 and day 6 after surgery (before and 4 hours after parnaparin administration). RESULTS: In 98.3% of patients receiving 4250 IU/day the peak anti-Xa levels were in the range of 0.1-0.4 IU/ml. Higher anti-Xa levels were observed in patients receiving 6400 IU/day: in 62.3% of these patients the peak anti-Xa levels were greater than 0.4 IU/ml. The anti-Xa levels measured 4 hours after injection on days 4 and 6 were not statistically correlated with BMI for either dose of parnaparin (p=0.077 and p=0.401 for 4250 or 6400 IU/day, respectively). CONCLUSION: The dose of 4250 IU/day seems adequate to achieve prophylactic anti-Xa levels in morbid obese patients undergoing bariatric surgery. Conversely, most of the patients receiving 6.400 IU/day show anti-Xa levels higher than the recommended prophylactic values.
