Abstract
PURPOSE It is unclear whether the age-related decline in the somatotropic axis stems from a reduced growth hormone (GH) production in the pituitary gland, or from a peripheral origin akin to an acquired GH resistance. With the help of a GHRH/arginine test, high-aged multimorbid hospitalized patients with IGF-I deficiency are to be tested to determine whether there is primarily a pituitary GH deficiency in the sense of a somatopause. METHODS Seventeen multimorbid patients (eleven men and six women) with a mean age of 82 years, with IGF-I concentrations below two standard deviations of 30-year-old men and women were identified. Patients suffered from a variety of common age-related stable diseases including coronary artery disease, chronic liver or kidney disease, chronic heart failure as well as acute conditions e.g., urosepsis or endocarditis. To assess the somatotropic axis they underwent a GHRH/arginine test. Results were evaluated using descriptive statistics. RESULTS In average, the peak concentration of GH after stimulation was 14.8 µg/L with a range from 2.76 to 47.4 µg/L. Taking into account both, gender and BMI (with a mean of 26.5 kg/m²) for each participant, the pituitary gland was adequately stimulated in 16 out of the 17 patients. No patient reported common side effects related to the GHRH/arginine test. CONCLUSION The somatotroph pituitary gland retains its secretory capacity in the advanced aged. Therefore, age does not seem to be the driving pacemaker for the functional decline of the somatotropic axis within the aged population.

Resistance training-induced improvement in physical function is not associated to changes in endocrine somatotropic activity in prefrail older adults. Arch Gerontol Geriatr 2022; 103:104792. [PMID: 36037722 DOI: 10.1016/j.archger.2022.104792] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Revised: 08/02/2022] [Accepted: 08/13/2022] [Indexed: 11/02/2022]
Abstract
CONTEXT Resistance training improves muscle function in prefrail and frail elderly. The role of the somatotropic axis in this physiologic process remains unclear. Insulin-like growth factor I (IGF-I) and its associated proteins Insulin-like growth factor binding protein 3 (IGFBP3) and acid labile subunit (ALS) build a circulating ternary complex that mediates growth hormone (GH) effects on peripheral organs and can serve as a measure of endocrine somatotropic activity. OBJECTIVE The aim of this study was to assess the association between resistance training-induced changes in physical performance and basal levels of IGF-I, IGFBP-3 and ALS in prefrail older adults. METHODS 69 prefrail community-dwelling older adults, aged 65 to 94 years, were randomly assigned to a 12-week period of strength or power training or to a control group. The study was registered at clinicaltrials.gov as NCT00783159. Serum concentrations of IGF-I, IGFBP-3 and ALS were measured at rest before and after the intervention. Hormonal differences were examined in relation to changes in physical performance assessed by the Short Physical Performance Battery (SPPB). RESULTS While resistance training led to significant improvements in SPPB score it did not induce significant differences in somatotropic hormone concentrations. Pre- and post-intervention changes in IGF-I, IGFBP-3, ALS or IGF/IGFBP-3 molar ratio were not related to the intervention mode, even after adjustment for age, sex, nutritional status, as well as SPPB and hormone concentrations at baseline. CONCLUSION Training-induced improvements in physical performance in prefrail older adults were not associated with significant changes in endocrine somatotropic activity.

Abstract
OBJECTIVES The present study aimed to investigate the effect of two different exercise training protocols on myocardial fibrosis and the expression of some growth factors in aged rats. METHOD Twenty-four male Wistar rats were randomly assigned to high-intensity interval training (HIIT) group, continuous exercise training (CET) group, and the control group. After 6 weeks of experiment, mRNA levels of fibroblast growth factor-2 (FGF-2), vascular endothelial growth factor (VEGF), adropin proteins, and myocardial fibrosis were assessed. RESULTS HIIT and CET induced a significant increase in the FGF-2 and adropin and a decrease in the myocardial fibrosis in compared with the control group. HIIT induced a significant increase in the VEGF if compared with the control group. There was no significant difference between CET and control group. CONCLUSION Six weeks of HIIT and CET attenuated age-related myocardial fibrosis thereby an increase in angiogenesis-related molecules in cardiac and endothelial tissues.

Abstract
Obesity and ageing place a tremendous strain on the global healthcare system. Age-related sarcopenia is characterized by decreased muscular strength, decreased muscle quantity, quality, and decreased functional performance. Sarcopenic obesity (SO) is a condition that combines sarcopenia and obesity and has a substantial influence on the older adults’ health. Because of the complicated pathophysiology, there are disagreements and challenges in identifying and diagnosing SO. Recently, it has become clear that dysbiosis may play a role in the onset and progression of sarcopenia and SO. Skeletal muscle secretes myokines during contraction, which play an important role in controlling muscle growth, function, and metabolic balance. Myokine dysfunction can cause and aggravate obesity, sarcopenia, and SO. The only ways to prevent and slow the progression of sarcopenia, particularly sarcopenic obesity, are physical activity and correct nutritional support. While exercise cannot completely prevent sarcopenia and age-related loss in muscular function, it can certainly delay development and slow down the rate of sarcopenia. The purpose of this review was to discuss potential pathways to muscle deterioration in obese individuals. We also want to present the current understanding of the role of various factors, including microbiota and myokines, in the process of sarcopenia and SO.

Abstract
Background The knowledge and attitude of health care providers are important and influential factors in providing care services to the elderly and need to be considered during the training course. Simulation in geriatric nursing education can be an opportunity for learners to experience the restrictions of the elderly. The present study was conducted to determine the effect of training through simulation on the attitude and knowledge of nursing students in elderly care. Methods This study was quasi-experimental with two experimental and control groups of pre and post-test, which was conducted on 70 nursing students of the 5th semester (two groups of 35 people). For the experimental group, the elderly simulation suit was worn for two hours, which was designed by the researcher and created sensory, physical, and motor restrictions similar to the elderly for students. Before and after the study, Kogan’s attitudes toward older people scale and Palmore’s “facts on aging quiz” were completed by students. The data were analyzed using an independent t-test and paired t-test using SPSS version 16 software. Results The mean scores of students’ knowledge in the experimental and control groups had no significant difference at the beginning of the study (p < 0.05). But the mean scores of knowledge in the experimental group before and after the intervention was (9.2 ± 2.6) and (15.3 ± 3.5), respectively, and in the control group before and after the intervention was (10.4 ± 2.9) and (11.3 ± 2.6), respectively, which had a statistically significant difference (p = 0.0001). The mean scores of students’ attitudes in the experimental and control groups had no significant difference at the beginning of the study (p < 0.05). The mean scores of attitude in the experimental group before and after the intervention was (114.69 ± 8.4) and (157.31 ± 10.7), respectively and in the control group before and after the intervention was (113.34 ± 13.6) and (108.5 ± 16.6), respectively, which was significantly different (p = 0.0001). Conclusions Based on the findings, the experience of aging restrictions through simulation has improved the knowledge and attitude of nursing students towards the elderly. Nursing education requires the growth of attitudinal skills, individuals’ beliefs, and creating empathy among them, so creating simulation opportunities can assist nursing students in the educational processes.

Abstract
Insulin-like growth factor (IGF) system stimulates growth, proliferation, and regulates differentiation of cells in a tissue-specific manner. It is composed of two insulin-like growth factors (IGF-1 and IGF-2), six insulin-like growth factor-binding proteins (IGFBPs), and two insulin-like growth factor receptors (IGF-1R and IGF-2R). IGF actions take place mostly through the activation of the plasma membrane-bound IGF-Rs by the circulating ligands (IGFs) released from the IGFBPs that stabilize their levels in the serum. This review focuses on the IGF-1 part of the system. The IGF-1 gene, which is expressed mainly in the liver as well as in other tissues, comprises six alternatively spliced exons that code for three protein isoforms (pro-IGF-1A, pro-IGF-1B, and pro-IGF-1C), which are processed to mature IGF-1 and E-peptides. The IGF-1R undergoes autophosphorylation, resulting in a signaling cascade involving numerous cytoplasmic proteins such as AKT and MAPKs, which regulate the expression of target genes. However, a more complex picture of the axis has recently emerged with all its components being translocated to the nuclear compartment. IGF-1R takes part in the regulation of gene expression by forming transcription complexes, modifying the activity of chromatin remodeling proteins, and participating in DNA damage tolerance mechanisms. Four IGFBPs contain a nuclear localization signal (NLS), which targets them to the nucleus, where they regulate gene expression (IGFBP-2, IGFBP-3, IGFBP-5, IGFBP-6) and DNA damage repair (IGFBP-3 and IGFBP-6). Last but not least, the IGF-1B isoform has been reported to be localized in the nuclear compartment. However, no specific molecular actions have been assigned to the nuclear pro-IGF-1B or its derivative EB peptide. Therefore, further studies are needed to shed light on their nuclear activity. These recently uncovered nuclear actions of different components of the IGF-1 axis are relevant in cancer cell biology and are discussed in this review.

Abstract
Objective : The aim of this study was to determine the effects of a physical activity program on static balance in elderly women. Method : The sample was randomly subdivided into an experimental group (EG; n=28; 65.64±2.36 years; BMI= 27.52±3.13) and a control group (CG; n=21; 66.84±2.31 years; BMI= 27.67±2.78). The EG participated in twice-weekly 60-minute sessions of physical activity for 12 weeks, with a perceived intensity level between 3 and 5 (CR10 scale). Static balance was evaluated using a baropodometric platform. Mean postural amplitude oscillations were measured in displacement from the center of pressure (COP), left lateral (LLD), right lateral (RLD), anterior (AD) posterior (PD) and elliptical (EA) area. Results : Repeated-measures analysis of variance showed a significant decrease in EG pre and post-test oscillations (p<0.05) in the COP, AD (∆=0.59;p=0.021), PD (∆=-0.91; p=0.001) and EA (∆=1.56; p=0.044) displacement. When comparing the groups, post-test amplitude oscillations in the COP, RLD (∆%=-7.40;p=0.006), AD (∆%=-30.63; p=0.007), PD (∆%=-42.96; p<0.001) and EA (∆%=-34.41;p=0.017) of the EG were significantly lower (p<0.05) than those of the CG. There were no significant LLD alterations. Conclusion : The results confirm that static balance improved with physical exercise in EG subjects.

Abstract
Abstract
The circulating level of cortisol is regulated by the hypothalamic-pituitary-adrenal axis through a neuroendocrine feedback circuit. This circuit can be activated by physiological stimuli such as stress, diseases, and exercise. High levels of serum cortisol hormone normally occur as a byproduct of aging, and can cause several types of damage to the organism and exacerbate immunosenescence. There is a great deal of variability in the cortisol response with regard to type, intensity, volume, and frequency of exercise. However, these relationships have been extensively studied with respect to the acute effects of exercise. Despite the well-known effects of acute exercise on cortisol response, it is unclear how it is affected by chronic exercise and the aging process. Therefore, the aim of this study was to conduct a review of studies that attempt to analyze the influence of chronic exercise on serum cortisol hormone in older people. In order to accomplish this goal, a review from 1970 to June 2012 period was performed using the following databases: Biological Abstracts, PsycINFO, PubMed/Medline, and the Web of Science. Eight articles met the criteria used in this study. Based on the included articles, chronic exercise may influence the serum levels of cortisol levels in older people. Despite this evidence, these results may not be generalized to the entire population of older people, given the few number of studies and especially because the studies showed diversity in variables and methodologies.

Abstract
Few studies have addressed changes in physical activity participation over time among the elderly. The authors hypothesized that there were distinct trajectories of physical activity level over time and identifiable predictors of such trajectories, as well as that the maintenance of regular physical activity, even below recommended levels, was associated with lower mortality risk. Using longitudinal data (1994-2009) from 433 initially high-functioning older women aged 70-79 years at baseline, a joint latent class and survival mixture model identified 4 activity trajectory classes: always active (16.6%), fast declining (19.2%), stable moderate (32.3%), and always sedentary (31.9%). Obesity, coronary artery disease, chronic obstructive pulmonary disease, depressive symptoms, low self-efficacy, mobility disability, and low energy were associated with sedentary behavior and/or a fast decline in activity. Women in the fast declining and always sedentary classes had hazard ratios for death of 2.34 (95% confidence interval: 1.20, 4.59) and 3.34 (95% confidence interval: 1.72, 6.47), respectively, compared with the always active class; no mortality difference was found between the stable moderate and always active groups (hazard ratio = 1.24, 95% confidence interval: 0.63, 2.47). Our findings suggest that physical activity does not have to be vigorous to be beneficial and that the gain may be the greatest among women who reported the lowest levels of activity.
