AbstractElderly adults have alterations in their gut microbiota and immune functions that are associated with higher susceptibility to infections and metabolic disorders. Probiotics and prebiotics, and their synbiotic combinations are food supplements that have been shown to improve both gut and immune function. The objective of this randomised, double-blind, placebo-controlled, cross-over human clinical trial was to study immune function and the gut microbiota in healthy elderly adults. Volunteers (n37) consumed prebiotic galacto-oligosaccharides (GOS; 8 g/d), probioticBifidobacterium lactisBi-07 (Bi-07; 109colony-forming units/d), their combination (Bi-07 + GOS) and maltodextrin control (8 g/d) in four 3-week periods separated by 4-week wash-out periods. Immune function was analysed by determining the phagocytic and oxidative burst activity of monocytes and granulocytes, whole-blood response to lipopolysaccharide, plasma chemokine concentrations and salivary IgA levels. Gut microbiota composition and faecal SCFA content were determined using 16S ribosomal RNA fluorescencein situhybridisation and HPLC, respectively. Primary statistical analyses indicated the presence of carry-over effects and thus measurements from only the first supplementation period were considered valid. Subsequent statistical analysis showed that consumption of Bi-07 improved the phagocytic activity of monocytes (P < 0·001) and granulocytes (P = 0·02). Other parameters were unchanged. We have for the first time shown that the probiotic Bi-07 may provide health benefits to elderly individuals by improving the phagocytic activity of monocytes and granulocytes. The present results also suggest that in the elderly, the effects of some probiotics and prebiotics may last longer than in adults.

Abstract Objectives Subtle deficits in memory in healthy elderly adults are considered to be a normal consequence of aging [i.e., age-associated memory impairment (AAMI)]. The prevalence of cognitive impairment without dementia in the elderly is estimated at 5.4 million, and every year roughly 12% of these individuals go on to develop dementia. Supplementation of citicoline (CDP-choline), a naturally occurring mononucleotide, has shown beneficial effects on memory function and behavior in populations with a wide range of impairments. Unfortunately, few studies have investigated the effects of citicoline supplementation on memory in healthy elderly adults with memory loss due to aging. Thus, the objective of this study was to investigate the effects of Cognizin®, a citicoline supplement, on memory in healthy elderly populations with AAMI. Methods A total of 100 healthy men and women between 50 to 85 years of age with AAMI participated in this randomized, double-blind, placebo-controlled trial. Subjects were randomized to receive placebo (n = 51) or Cognizin® (n = 49; 500 mg/day) for 12 weeks. Memory functions were assessed at baseline and end of the intervention (12 weeks) using computerized tests (Cambridge Brain Sciences, Ontario, Canada). Safety measurements included adverse events query, hematology and clinical chemistry. Results A total of 99 out of 100 subjects completed the study in its entirety. After the 12 week intervention, subjects supplemented with Cognizin® showed significantly greater improvements in episodic memory (assessed by the Paired Associate test) compared to those on placebo. Scores for composite memory, calculated using the scores of four memory tests (Spatial Span, Monkey Ladder, Paired Associate, and Digit Span) also improved to a greater extent following Cognizin® supplementation compared to placebo. There were no adverse events related to a study product and hematology and clinical chemistry were stable throughout the intervention. Conclusions Dietary supplement of Cognizin® for 12 weeks improved overall memory performance, especially episodic memory, in healthy males and females with AAMI. The findings suggest that regular consumption of Cognizin® may be safe and potentially beneficial against memory loss due to aging. Funding Sources Kyowa Hakko Bio Co., Ltd.

ABSTRACT Objective: To assess flexibility and balance in healthy elderly subjects with or without major depression, by means of two different programs: aerobic exercises and flexibility and balance exercises. Methods: A randomized, double-blind controlled study in which each sample was the control of itself. Research subjects were 19 healthy elderly individuals, aged between 60 and 90 years, of both genders, referred to the Department of Geriatrics of the Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, with or without the diagnosis of major depression, and sedentary or that had not engaged in physical activity for at least 6 months. Results: Subjects with major depression, as well as those without depression, showed signifcant improvement in flexibility and balance, especially in the group that did aerobic exercises. Conclusion: The results of this investigation reinforce the relevance of physical exercises for the elderly with major depression, as this is an important tool for treating and following-up this group of patients.

Adverse effects of medications that occur at low frequency or low severity are often not detected in the current framework of drug approval and monitoring. Of particular concern are potential behavioral consequences such as depression or cognitive dysfunction that may occur from commonly prescribed medications. This study explores the use of measuring daily affect, both positive and negative, as a method for detecting clinically relevant affective toxicity from medications commonly prescribed to older adults. Findings from this study suggest that metoclopramide may have the potential for causing significant changes in affect among healthy elderly adults. This may suggest that more vulnerable or disabled adults may be at even greater risk for affective changes related to this medication.

It is recognised that ageing induces various changes to the human colonic microbiota. Most relevant is a reduction in bifidobacteria, which is a health-positive genus. Prebiotics, such as galacto-oligosaccharides (GOS), are dietary ingredients that selectively fortify beneficial gut microbial groups. Therefore, they have the potential to reverse the age-related decline in bifidobacteria and modulate associated health parameters. We assessed the effect of GOS mixture (Bimuno (B-GOS)) on gut microbiota, markers of immune function and metabolites in forty elderly (age 65–80 years) volunteers in a randomised, double-blind, placebo (maltodextrin)-controlled, cross-over study. The intervention periods consisted of 10 weeks with daily doses of 5·5 g/d with a 4-week washout period in between. Blood and faecal samples were collected for the analyses of faecal bacterial populations and immune and metabolic biomarkers. B-GOS consumption led to significant increases in bacteroides and bifidobacteria, the latter correlating with increased lactic acid in faecal waters. Higher IL-10, IL-8, natural killer cell activity and C-reactive protein and lower IL-1β were also observed. Administration of B-GOS to elderly volunteers may be useful in positively affecting the microbiota and some markers of immune function associated with ageing.

Pegagan (Centella asiatica L) has been traditionally used to treat wounds, disordered nerve system, blood circulation, and prevent muscle disorders. Extract of Pegagan was considered safe and non-toxic as the acuut and chronic toxicity tests on male SD rats were not significant. It meant that further study was potential to be proceeded. Study of C.asiatica on muscle function of the elderly has not been done, therefore this study is aimed to observe  effects of C.asiatica extract on muscle masses, holding hands, walking speed (4.57 meter), walking test (6 minutes), and Time Up and Go test of the elderly. This study is designed for clinical double blind study with 2 groups of people, these are C. asiatica (18 people) treated with capsul (550 mg C. asiatica extract/day for 90 days) and placebo (17 people). This study is performed in the RSUP Dr. Sardjito hospital at the geriatric division. Subjects for this study were healthy elderly people and fit with the criteria of subjects for experiment. Result of the study, muscle masses do not decrease and all the measurements are not different with that of placebo. Except that the walking speed (6 minutes) of the treated subjects is better than that of the placebo. The conclusion of the study, the capsul containing C. asiatica extract (550 mg, once a day for 90 days) increases the strengh of hands holding, and the walking test (6 minutes) almost twice better than that of the placebo although the muscle masses does not increase significantly.

According to estimation, India currently has 6.7% over 65 years of age, which is expected to increase to 20% by the year 2050. As growing old is a part of the life cycle, the effect of time is bound to happen and is unavoidable. The Kalajajara is a Swabhavika vyadhi, wherein, it is clearly mentioned that Swabhava balapravritta vyadhis being Yapya, can be managed through Bhojana, Paana, and Rasayana. Vriddadaru Rasayana is one such Rasayana mentioned in Gadanigraha especially for the elderly to promote healthy ageing and helping to prevent old age problems. Aims and objectives: To assess the effect of Vriddadaru Rasayana in improving the general body health and quality of life in the apparently healthy elderly subjects. Methodology– A Randomized double blind clinical study where 20 healthy elderly subjects were administered with Vriddadaru Rasayana for a period of 12 weeks. Observations and Results- Vriddadaru rasayana showed improvement in Ayurvedic parameters like Twakparushata, Slataasti, Slata sandhi, Utasahahani and Parakramahani but when compared with regard to objective parameters Vriddadaru rasayana showed significant values in DHEAS levels and 6MWT. Conclusion: Vriddadaru does Vatashamana, balancing the Doshas, increasing the Utsaha and Parakrama and helps in improving the Agni thus helping in Dhatuposhana in the elderly.

Medications with anticholinergic properties, when taken at therapeutic doses, are known to adversely affect memory functioning in young adults and the elderly. However, their impact at lower doses in geriatric persons has been less thoroughly studied. We investigated the impact of a single 2-mg dose of trihexyphenidyl on memory functioning in 20 healthy elderly subjects using a within-subjects, double-blind comparison with a placebo. Memory functioning was evaluated using subtests of the Wechsler Memory Scale. Subjects also rated the perceived impact of medication on their performance following memory testing.Results indicated that the single 2-mg dose of trihexyphenidyl produced impaired performance on measures of immediate and half-hour delayed recall of complex verbal and visual material when compared to the placebo condition. However, differences were not found on several other memory measures, including general orientation, attention-concentration, and learning of word associations. The significance of these selective memory deficits and suggestions regarding future research are discussed.
