Abstract Background In general, plant protein intake was inversely associated with mortality in studies in middle-aged adults. Our aim was to evaluate the long-term associations of animal and plant protein intake with mortality in older adults. Methods A prospective cohort study including 1,139 community-dwelling older adults (mean age 75 years, 56% women) living in Tuscany, Italy, followed for 20 years (InCHIANTI study) was analyzed. Dietary intake by food frequency questionnaires and clinical information were assessed five times during the follow-up. Protein intakes were expressed as percentages of total energy. Time-dependent Cox regression models adjusted for confounders were used to assess the association between plant and animal protein intake, and mortality. Results During the 20-years of follow up (mean: 12y), 811 deaths occurred (292 of cardiovascular- and 151 of cancer-related causes). Animal protein intake was inversely associated with all-cause (HR per 1% of total energy from protein increase, 95%CI: 0.96, 0.93-0.99) and cardiovascular mortality (HR per 1% of total energy from protein increase, 95%CI: 0.93, 0.87-0.98). Plant protein intake showed no association with any of the mortality outcomes, but an interaction with baseline hypertension was found for all-cause and cardiovascular mortality (p<0.05). Conclusions Animal protein was inversely associated with all-cause and cardiovascular mortality in older adults. Further studies are needed to provide recommendations on dietary protein intake for older adults.

Vaginal Mucosa

An important issue in the treatment of vaginitis is the amount of time the drug remains on the vaginal mucosa. If the contact time is too short, the drug cannot work effectively to ensure the correct pH in the vaginal environment. This study evaluated formulations of globules containing sodium alginate, lactic acid and chitosan with different pH and rheological properties. The experimental studies revealed that it is possible to produce a preparation with optimal pharmaceutical and application properties. The use of an appropriate ratio of lactic acid to chitosan in the complex and the appropriate concentration of sodium alginate produces a preparation with excellent properties to coat the surface of the vaginal mucosa.

Abstract Objective: The aim of the present study was to investigate the differences between the consumption of plant-based v. animal-based protein-rich diets on successful ageing, as well as to identify the optimal combination of dietary protein intake for facilitating successful ageing in people aged >50 years. Design: A combined analysis was conducted in older adults of the ATTICA and MEDIS population-based cross-sectional studies. Anthropometrical, clinical and sociodemographic characteristics, lifestyle parameters, dietary habits and level of protein intake were derived through standard procedures. Successful ageing was evaluated using the validated Successful Aging Index (SAI) composed of ten health-related social, lifestyle and clinical characteristics. Setting: Athens area and twenty Greek islands. Participants: A total of 3349 Greek women and men over 50 years old. Results: Participants with high consumption of plant proteins were more likely to be male, physically active, with higher daily energy intake, higher adherence to the Mediterranean diet and higher level of SAI (P < 0·001). Participants with ‘Low animal & High plant’ and ‘High animal & High plant’ protein consumption had a 6 and 7 % higher SAI score, respectively, compared with the other participants (P < 0·001). In contrast, ‘Low animal & Low plant’ and ‘High animal & Low plant’ protein intake was negatively associated with SAI as compared to the combination of all other consumption categories (P < 0·02). Conclusions: The consumption of a plant-based protein-rich diet seems to be a beneficial nutritional choice that should be promoted and encouraged to older people since it may benefit both individual’s health and prolong successful ageing.

Abstract Objectives Metabolic syndrome is a precursor to many leading causes of death in the United States including cardiovascular disease, stroke, and diabetes. Diet plays a major role in preventing or exacerbating the development of metabolic syndrome. Increasing plant protein intake may help to reduce risk of developing metabolic syndrome. The purpose of this study was to examine the possible relationship between metabolic syndrome progression and % of protein from plant sources in the diet. Methods The ARIC dataset was used to compare changes in the number of metabolic syndrome criteria (0-5) over a 9-year period to average % of protein from plant sources for 10,038 Americans age 45–64. Quartiles of plant protein intake were controlled for important covariates in linear regression. Results As hypothesized, quartiles with higher percentages of protein intake from plant sources showed a decrease in metabolic syndrome score [B (change in metabolic syndrome score over 9 years per plant protein quartile) = -0.039; 95% confidence interval (CI): -0.063, -0.016] over 9 years of follow up. Waist circumference was the most significantly associated metabolic syndrome factor (B = -0.053; 95% CI -0.030, -0.011). A decrease in BMI was similarly correlated with higher intakes of plant proteins (B = -0.077; 95% CI -0.214, -0.0112). Conclusions These results suggest that a higher intake of plant proteins could be protective against increased BMI, waist circumference, and worsening metabolic syndrome and therefore may reduce risk of cardiovascular disease, diabetes, and stroke.

The main objective of the present work was to study the role of carbon nanotube (CNT) on the microstructure development and physical, mechanical, and rheological properties of poly(lactic acid) (PLA)/natural rubber (NR)/CNT hybrid nanocomposites. The PLA/NR blend samples with constant blend ratio (90/10) were prepared by melt mixing in a laboratory internal mixer at a temperature of 190°C. The behavior of the PLA/NR blend was examined depending on the CNT content (0.5–6 wt%). The droplet size and droplet size distribution of the NR phase decreases with the increase in CNTs content. This could be explained in terms of compatibilizing effect of CNT and the changing of the viscosity ratio of the blend phases. The development of the microstructure and the physical properties of the blend were also investigated according to the CNT contents by measuring the linear viscoelasticity. The elongational behavior and mechanical properties of the blends were strongly dependent on the location of the CNT. The CNT worked as an efficient compatibilizer and also it worked as a reinforcing filler making the matrix more rigid.
