Introduction: Osteoporosis is one of the main causes of bone fractures in old age. The examination of osteoporosis in the elderly is very complicated due to the heterogeneity of the aging process. This study aimed to investigate the correlation of the TNC gene in the patients with an inherited and very rare osteoporosis syndrome. The importance of this study was the identification of a specific biomarker for the osteoporosis process in a monogenic disease. Methods: In this case-control study, the patients with Osteogenesis Imperfecta were used as a simple and monogenic model to investigate the possibility of TNC gene role in osteoporosis. For this purpose, TNC protein network and its related biological pathways were firstly evaluated by bioinformatic analysis. Then, skin biopsies were taken from 3 patients with inherited osteoporosis syndrome called Osteogenesis Imperfecta and two healthy individuals. After culturing the biopsy, fibroblast cells were isolated from keratinocyte cells. Then, the total RNA of each sample was extracted from two different passages and cDNA was synthesized. Subsequently, the expression of TNC gene was measured by Real-time PCR in healthy and patient cells using various replicates. Results: TNC network proteins are significantly associated with the biological pathways involved in the ossification process. The expression of the TNC gene was assessed in wild type and patient cells. Finally, our results confirmed a significant increase in the expression of TNC in the patients’ compared to wild types’ cells by using technical and biological replicates (p:0.005, p:0.007) and Student t-test. In this study, Excel and GraphPad Prism 5.0 software (GraphPad Software, Inc., San Diego, CA) were used. Conclusion: Increased expression of TNC gene in a monogenic osteoporosis syndrome can indicate the potential role of this gene in the process of bone loss and introduce this gen as a new biomarker for osteoporosis. The study on rare Osteogenesis Imperfecta syndrome is a simple and monogenic model to investigate the heterogeneous osteoporosis. Therefore, the expression of the candidate gene needs to be evaluated and confirmed in an appropriate statistical population composed of patients with osteoporosis.

Treatable Condition

Osteoporosis is now a treatable condition with an abundance of evidence for the efficacy of certain therapeutic strategies in preventing recurrent fractures. Most of these treatments act by improving bone mineral density through inhibition or reduction of bone resorption. For those women who are unable to take HRT; bisphosphonates, calcium, vitamin D, calcitriol or calcitonin may confer certain benefits. The bisphosphonate alendronate reduces both vertebral and long bone fractures, an effect seen soon after starting treatment. The changes in BMD and fracture reduction are less with the use of etidronate but it is certainly beneficial in reducing recurrent vertebral fracture. In the elderly calcium and vitamin D in combination can reduce non-vertebral and hip fracture and supplemental calcium of 1 g/day has been predicted to reduce bone loss and thus hip fractures by 22%. Evidence that calcitriol or calcitonin reduce fracture incidence is not good but calcitonin has been shown to have analgesic properties in those with acute vertebral fracture. The role of calcitriol is less certain and should be reserved for women with vertebral fractures in whom HRT or bisphosphonates cannot be used.

Fat Soluble Vitamins

AbstractFollowing a discussion on the daily energy and protein requirements of elderly people, the authors will go on to talk about vitamin needs and the role of the four fat-soluble vitamins (A, D, E, and K). They point out that vitamin requirements in old age do not essentially differ from adult people’s, but they must take account of the fact that the body’s vitamin stores might get filled up, which may reduce vitamin needs, on the one part, but the altered physiological processes may increase them, on the other. Regarding the case of fat-soluble vitamins, reduced fat absorption, decreased vitamin storage capacity of the liver, reduced dietary intake, partial deficiency of digestive enzymes, and absorption disorders in the intestines may all lead to vitamin deficiencies. Problems may also arise due to multiple vitamin overdose developed either as a consequence of overconsumption of vitamin tablets or because the body’s vitamin stores are constantly filled up to maximum capacity. Positive and negative changes resulting from the consumption of several times the daily dose recommendations are covered as well. The authors show that A, D, E, or K vitamin deficiency occurs very rarely in the case of a normal diet; however, great care must be taken in order to meet vitamin D and, simultaneously, calcium requirements so that to avoid osteoporosis and an increased risk of bone fractures in elderly people. The paper discusses the fat-soluble vitamin needs of the elderly and, where necessary, specifies the requirements for men and women separately, while also touching upon those foodstuffs and methods that can contribute to the optimal satisfaction of the elderly people’s vitamin needs.

Care Costs

Raising numbers of elderly lead to a dramatic shift in demographics, accompanied by an increase in non-communicable diseases such as cancer, cardiovascular disease and dementia. All these conditions are thought to be modifiable by diet to some degree and mounting evidence indicates that improved intakes of certain vitamins can slow their progress. Strong evidence exists for the beneficial effect of vitamin D on the risk of bone fractures. Moreover, as chromosomal damage is a risk factor for dementia, supplementation with nutrients preventing these impairments are thought to have a beneficial effect on cognitive decline. However, the aging progress strongly affects nutrient intakes and utilisation due to social, physical and psychological changes. Data from dietary surveys suggest that many of the elderly in Europe have intakes for various vitamins that are well below the recommendations. The situation appears to be even more critical for elderly in institutions such as care homes. Given the increasing number of elderly and the importance of an adequate supply with vitamins, more research is warranted to find nutritional solutions to improve their wellbeing and health - which in the long run can be expected to contribute to reduce the ever increasing health care costs.

Abstract. Prospective Memory (PM; i.e., the ability to remember to perform planned tasks) represents a key proxy of healthy aging, as it relates to older adults’ everyday functioning, autonomy, and personal well-being. The current review illustrates how PM performance develops across the lifespan and how multiple cognitive and non-cognitive factors influence this trajectory. Further, a new, integrative framework is presented, detailing how those processes interplay in retrieving and executing delayed intentions. Specifically, while most previous models have focused on memory processes, the present model focuses on the role of executive functioning in PM and its development across the lifespan. Finally, a practical outlook is presented, suggesting how the current knowledge can be applied in geriatrics and geropsychology to promote healthy aging by maintaining prospective abilities in the elderly.

Galectin 3

For many with heart failure, including the elderly and those with a preserved ejection fraction, both risk stratification and treatment are challenging. For these large populations and others there is increasing recognition of the role of cardiac fibrosis in the pathophysiology of heart failure. Galectin-3 is a novel biomarker of fibrosis and cardiac remodelling that represents an intriguing link between inflammation and fibrosis. In this article we review the biology of galectin-3, recent clinical research and its application in the management of heart failure patients.

Intergenerational Education

Introduction: Intergenerational education encourages cooperation and interaction between two or more generations through experiences, knowledge, skills, attitudes and values. Objective: The main objective of our research was to know the benefits at the psychological, social and educational level of intergenerational education. Methods: This is mixed-type research establishing relationships between young and old. The sample consists of a total of 94 people, 47 young people (aged between 21 and 40 years old) and 47 older (aged between 65 and 85 years). We promote the development of a mixed methodology to know if after the implementation of an intergenerational program we have obtained benefits in the elderly participants. Results: Considering the results we can say that the benefits at the psychological, social and educational level have been very remarkable of our elders. Conclusions: We must bet on intergenerational relationships as an ideal within our daily practice achieving a healthy aging, benefiting continuity in an active social role of our elders.

The Relationship

Our spatial mental representations allow us to give refined descriptions of the environment in terms of the relative locations and distances between objects and landmarks. In this study, we investigated the effects of familiarity with the everyday environment, in terms of frequency of exploration and mode of transportation, on categorical and coordinate spatial relations, on young and elderly participants, controlling for socio-demographic factors. Participants were tested with a general anamnesis, a neuropsychological assessment, measures of explorations and the Landmark Positioning on a Map task. The results showed: (a) a modest difference in performance with categorical spatial relations; (b) a larger difference in coordinate spatial relations; (c) a significant moderating effect of age on the relationship between familiarity and spatial relations, with a stronger relation among the elderly than the young. Ceteris paribus, the role of direct experience with exploring their hometown on spatial mental representations appeared to be more important in the elderly than in the young. This advantage appears to make the elderly wiser and likely protects them from the detrimental effects of aging on spatial mental representations.
