Intake of dietary phytoestrogen and indices of antioxidant and bone metabolism of pre- and post-menopausal Korean women

A group of 101 women, aged 40-65 years consisted of 48 premenopausal subjects and 53 postmenopausal ones living in Daegu and Gyeongbuk area in Korea were evaluated with their general characteristics, lifestyle factors, nutrient and phytoestrogen intakes, blood and urinary indices concerning antioxidant status and bone metabolism. Body mass index (BMI), waist hip ratio (WHR) and systolic blood pressure (SBP) of the postmenopausal women were significantly higher (23.8, 0.86, and 126.9 mmHg, respectively) than those of the premenopausal women (22.6, 0.82, and 115.9 mmHg; respectively). Nutrient intakes of the postmenopausal and premenopausal groups were not different except lower fat intake and higher dietary fiber and iron intakes in the postmenopausal group. Daily total phytoestrogen intake was significantly higher in the postmenopausal group (48.54 mg) than the premenopausal (31.41 mg) and was resulted mostly from higher intakes of daidzein and genistein from soy and soy products (45.42 mg vs 28.91 mg). Serum genistein level and excretion of enterolactone, major lignan metabolite, were not very different between the two groups. Serum retinal and α- tocopherol levels were higher in the postmenopausal group but TBARS levels were not different between the two groups. Serum osteocalcin (7.18 ng/mL) and urinary deoxypyridinoline (7.15 nmol/mmol creatinine), in the postmenopausal group were significantly higher than those in the premenopausal group (4.80 ng/mL, 5.95 nmol/mmol creatinine). Urinary excretion of enterolactone was positively correlated with serum osetocalcin in premenopausal women and serum genistein negatively correlated with the urinary DPD in postmenopausal women. Dietary phytoestrogen intake was negatively correlated with serum level of TBARS in all subjects. It is concluded that the effect of total phytoestrogen intake is beneficial on body antioxidant status in all middle-aged women regardless of menopause but the effect on bone metabolism appears different by the type of the phytoestrogen and the menopausal state.

Reliability and validity of indices of hand-grip strength and endurance

Background/aim: Grip strength is useful in clinical practice for the assessment of disease and/or rehabilitation progression. Brief maximal gripping is seldom required in everyday occupations, with repeated or sustained gripping at sub‐maximal power more commonly involved. It has been proposed that assessment of both maximal hand‐grip force and endurance is utilised. While the suitability of maximal contraction measures has been clearly established, the reliability and validity of other hand‐grip indices have not been investigated. This study examined the reliability of various hand‐grip indices and their validity in relation to distance walked during the six‐minute walk test, a standardised exercise capacity test. Methods: Subjects undertook static sub‐maximal (50%) and maximal force contraction hand‐grip testing from which various indices were derived, and six‐minute walk testing from which distance walked was determined. Testing was repeated on three separate occasions for determination of test–retest reliability. Results: Pre‐ and post‐fatigue maximal contraction measurements demonstrated excellent test–retest reliability and validity. Conversely, other hand‐grip indices were shown to be unreliable and exhibited no relationship with distance walked and hence concurrent validity could not be established. Conclusions: Based on the results of this study, it is recommended that pre‐ and post‐fatigue maximal contraction may be utilised for the assessment of client ability and progression due to their established validity and test–retest reliability. However, previously proposed measures of fatigue such as endurance (duration of sustained contraction), Strength Decrement Index and work performed (function of endurance and force of contraction) are unreliable and invalid and may have limited use in clinical practice.     

Evaluation of impact of temperature and pH alterations on the size and antigenicity of meningococcal serogroup A and X polysaccharides and conjugates

The changes in the recommended storage conditions of the glycoconjugate vaccines against Neisseria meningitidis (Men) serogroup A and serogroup X can affect its activity or potency. Elevated temperature and the change in pH may result in the physical instability leading to the size degradation of the polysaccharide (PS) and subsequent loss of PS epitopes. Moreover, high temperature may also result in protein aggregation and altered tertiary structure of the protein in the conjugate. Consequently, the construction of a potent glycoconjugate is dependent on optimal temperature and pH. The changes in both these conditions can also affect the production of a capsular polysaccharide (PS) and its conjugation to a protein carrier and may also affect the integrity of the vaccine molecule including the maintenance of the protective epitopes. In our study we have used inhibition ELISA as a tool to assess the impact of temperature and pH alterations on the antigenicity of N. meningitidis serogroup A and X, PS and conjugates and their correlation with the size distribution analysis using high pressure size exclusion chromatography. The studies on pH alterations from 5 to 9 led to minimal impact on size and antigenicity of all antigens, however, an elevated temperature adversely impacted the antigen size as well as antigenicity to varying extent. Results indicate the higher stability of MenX PS and conjugate as compared to that for MenA counterparts at elevated temperatures. Furthermore, both the MenA and MenX conjugates appears to be more stable as compared to the corresponding PSs.
