Total urinary polyphenols and longitudinal changes of bone properties. The InCHIANTI study

The aim of this study was to evaluate the association of levels of urinary total polyphenols considered as a proxy measure of polyphenol intake, with longitudinal changes of bone properties, in the InCHIANTI study. Dietary intake of polyphenols appears to be associated with future accelerated deterioration of bone health.

INTRODUCTION

Polyphenols, micronutrients ingested through plant-based foods, have antioxidant and anti-inflammatory properties and may contribute to osteoporosis prevention. We evaluated associations of high levels of urinary total polyphenols (UTP), a proxy measure of polyphenol intake, with longitudinal changes of bone properties in a representative cohort of free-living participants of the InCHIANTI study.

METHODS

The InCHIANTI study enrolled representative samples from the registry list of two towns in Tuscany, Italy. Baseline data were collected in 1998 and follow-up visits in 2001 and 2004. Of the 1453 participants enrolled, 956 consented to donate a 24-h urine sample used to assess UTP, had dietary assessment, a physical examination, and underwent a quantitative computerized tomography (pQCT) of the tibia. From pQCT images, we estimated markers of bone mass (BM), diaphyseal design (DD), and material quality (MQ). Mixed models were used to study the relationship between baseline tertiles of UTP with changes of the bone characteristics over the follow-up.

RESULTS

At baseline, higher levels of UTP were positively correlated with markers of BM, DD, and MQ. Compared with lower tertile of UTP, participants in the intermediate and highest tertiles had higher cortical bone area, cortical mineral content, and cortical thickness. However, participants in the intermediate and highest UTP tertiles experienced accelerated deterioration of these same parameters over the follow-up compared with those in the lowest UTP tertile.

CONCLUSIONS

Dietary intake of polyphenols estimated by UTP and dietary questionnaire was associated with long-term accelerated deterioration of bone health. Our study does not support the recommendation of increasing polyphenol intake for osteoporosis prevention.

Mediterranean diet and physical activity improve posture, fat mass and salivary pH

Many researchers have revealed that diet and physical activity influence metabolic function and posture in various stages of life. This paper aims to combine them and demonstrate how they could promote a healthy lifestyle. For this purpose, 14 healthy subjects followed a three-month protocol combining physical activity with dietary advice. At the end of the protocol, the results of the study underlined a significant reduction in fat mass, an improvement in salivary pH, and a realignment and rebalancing of body segments. .

Task-Oriented Physical Exercise Using Postural Re-Alignment with Body Weight Support in Chronic Stroke

The recovery of functional gait is the main target for subjects who have suffered a stroke. The methods designed to improve balance and gait appear to be essential for skills and autonomy and to reduce the costs of assistance. The aim of our study was to evaluate the improvement of stroke victims in the chronic phase through the rehabilitation of gait, balance and posture using postural re-alignment with specific body weight support. The study includes 20 subjects with residual hemiparetic gait after stroke. Evaluation with international rating scales, gait analysis and stabilometric test was carried out at the beginning and after the 1st and the 3rd month of therapy; a follow-up control was made 3 months after the end of the rehabilitation program. All subjects underwent the rehabilitation protocol with Dynamic Antigravity Postural System 2 times a week for 3 months and were also treated with high efficiency focused acoustic waves (ViSS) to increase strength and muscular endurance (300Hz) or to reduce spastic hypertonia (200–120 Hz). The study shows a significant improvement in gait and balance with the persistence of results at the follow-up 3 months after the end of treatment. The subjects showed an increase in walking speed, greater stability and a consequent reduction of sedentary lifestyle with less risk of complications or recurrence. In conclusion this rehabilitation program is efficient for posture and walking quality.

Visual sensory disability: rehabilitative treatment in an aquatic environment

The outcome of this study is based on the concept of the enormous potentiality that is expressed, after the elimination of myofascial and articular compensation, from the body system. 10 low vision and blind subjects aged between 35 and 50 years. The subjects performed 10 sessions (2/week) for 5 weeks. Each session consisted of a training in the gym (30 minutes) and hydrokinetic therapy (45 minutes) All the subjects at the beginning (T0) and at the end (T1) of the rehabilitation program were tested by static baropodometry and the stabilometric (Milletrix, Diagnostic support, Rome, Italy). Our results shows an increase of the total area of support surface (p0.05). The stabilometry results shows an improvement of the orthostatic balance, sway area and the ellipse area decrease respectively 15% (236,9vs201 p≤0.05) and 41% b(p≤0.05). Thus, the energy expenditure of the patient in maintaining the orthostatic position without visual afferences is lower. Rehabilitative treatment in an aquatic environment resulted effective in improving posture and balance in all patients with increased precision in the execution of the step, which implies less effort during walk, less energy consumption and better quality of life.

The Prevalence of Rheumatoid Arthritis in the South of Jordan

The aim of this study is to evaluate the prevalence of rheumatoid arthritis in the south of Jordan. The study was carried out between January, 2005 and December, 2008; 2,220 adults aged between 16 and 75 years were evaluated for the presence of rheumatoid arthritis disease according to the American Rheumatism Association 1987 criteria. The results showed that the prevalence of rheumatoid arthritis was 0.36% in the general population; the prevalence in males was 0.34% and in females it was 0.39%. In conclusion, the prevalence of rheumatoid arthritis is extremely low in the south of Jordan with a slight female predominance. American Rheumatism Association criteria continued to be the most useful criteria for the diagnosis of rheumatoid arthritis.
