Plasma Androstenedione Concentration Can Discriminate Frail versus Non-Frail Men with Prostate Cancer under Androgen Deprivation Therapy. Biomolecules 2023; 13:1642. [PMID: 38002324 PMCID: PMC10669122 DOI: 10.3390/biom13111642] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Revised: 09/26/2023] [Accepted: 11/09/2023] [Indexed: 11/26/2023] Open
Abstract
BACKGROUND Androgen deprivation therapy (ADT) is a mainstay of prostate cancer in both adjuvant and palliative settings. Since androgens are crucial for functional status and psychological functions, we evaluated whether blood testosterone, androstenedione, or DHEA concentrations were associated with functional status and psychological alterations in patients with localised (PCa) or metastatic prostate cancer (mPCa) receiving ADT with analogues of luteinising hormone-releasing hormone (LHRH). METHODS The five Fried criteria were considered to identify frailty syndrome. In addition, complementary evaluations were carried out to measure other variables of interest. Sleep quality was assessed using the Athens Insomnia Scale, cognitive functions were assessed using the Mini-Mental State Examination, and symptoms of depression were measured using the Yesavage Geriatric Depression Scale. Logistic regression analysis was performed to determine if the androgens level could be related to frailty syndrome, sleep impairment, depressive symptoms, and cognitive functions. RESULTS The results of the multivariate analyses show that high concentrations of androstenedione were significantly associated with frailty syndrome in both groups (p = 0.018; odds ratio = 4.66, 95% confidence interval [1.30-16.6]). There were significant relationships between frailty syndrome and the systemic concentration of androstenedione (p = 0.01), but not the concentration of testosterone (p = 0.60) or DHEA (p = 0.42). In addition, the results of the non-parametric tests show significant results between a decreased gait speed in the two groups (metastatic and localised) and the concentration of androstenedione (p = 0.015). High androstenedione levels were associated with a slow walking speed in the mCaP group (p = 0.016), while high testosterone levels were associated with a better walking speed in the localised CaP group (p = 0.03). For the concentration of androstenedione in plasma, the area under the curve was 0.72, with a 95% CI of 0.55-0.88 with acceptable values, and with a cut-off point of 4.51 pg/mL, a sensitivity of 82.9%, and specificity of 53.8%. No relationships between the concentration of androgens in plasma and sleep quality, cognitive functions, or symptoms of depression suggest that the changes were specific to frailty syndrome. CONCLUSIONS Further research into the role of androstenedione should be evaluated in follow-up studies in order to recommend its use as a suitable biomarker of frailty syndrome in prostate cancer patients.

Abstract
For purposes of this review, we defined toileting disability as a result of practices, procedures, or conditions that result in an individual requiring assistance using the bathroom. This scoping review synthesizes existing knowledge of extrinsic and/or intrinsic factors that might lead to or be associated with toileting disability and identified knowledge gaps related to toileting disability in older adults residing in long-term care or assisted living facilities. A search of 9 electronic databases and the gray literature identified 3613 articles. After exclusions and screening of the full text of 71 articles, 7 remaining eligible articles mapped research activity and identified knowledge gaps in this area. Only 1 study used toileting disability as the primary outcome; it was present in 15% of older adults without dementia living in long term-care facilities (a subgroup that comprised 34% of all residents). The other 6 articles examined factors and treatment of overall activities of daily living (ADL) performance as their primary outcome; in these, toileting disability was added to other difficulties, yielding a summary ADL outcome score. No study reported the incidence, distribution, or factors that affect toileting disability in long-term care; findings of this scoping review suggest a rich research agenda for future investigation.

Abstract
BACKGROUND Activity of daily living declines in female elderly, which not only increases hospitalization and mortality rates, but also aggravates individual and societal burden. Large samples are needed to elucidate the relationships of plasma sex hormone levels with activity of daily living in Chinese female centenarians to better understand the effects of hormone-replacing therapy. OBJECTIVE As the first time in the world, the current study was designed to investigate the relationships of plasma sex hormone levels with activity of daily living in Chinese female centenarians. PARTICIPANTS China Hainan Centenarian Cohort Study was carried out in 18 cities and counties of Hainan Province. MAIN MEASURES Home interview, physical examination and blood analysis were carried out in 583 female centenarians following standard procedures. Barthel Index was used to assess the activity of daily living. KEY RESULTS Median age of all female centenarians was 102 years, with the range from 100 to 115 years. Median values of Barthel Index were 85(60-90). In multivariate linear regression analyses, Barthel Index values were inversely associated with plasma luteinizing hormone (LH), follicle-simulating hormone (FSH), testosterone, progesterone and estradiol levels (P<0.05 for all). CONCLUSION Plasma sex hormone levels, including LH, FSH, testosterone, progesterone and estradiol, had significant relationships with activity of daily living in Chinese female centenarians.

Abstract
Testosterone levels and physical activity each play important roles in men's health, but the relationship between the two remains unclear. We evaluated the cross-sectional association between self-reported total physical activity and serum testosterone levels in 738 men (mean age 42.4 years, range 20-≥85 years) who participated in National Health and Nutrition Examination Survey 1999-2004. We compared geometric mean testosterone concentrations measured by radioimmunoassay (RIA) and calculated the odds ratio (OR) of having low or low normal testosterone (≤3.46 ng/mL) across tertiles of total physical activity in all men, and men stratified by age (20-49, ≥50 years), and obesity status (BMI < 30, ≥30 kg/m(2) ). The geometric mean testosterone concentration was 5.31 ng/mL; 18.6% of the men had low or low normal serum testosterone levels. Physical activity tertiles were not associated with testosterone levels overall, or when stratified by age or obesity status. Similarly, there was no association between physical activity tertiles and the odds of low or low normal testosterone, overall or by age. However, among non-obese men, those in the highest physical activity tertile were significantly less likely to have low or low normal testosterone than those in the lowest tertile (OR 0.50; 95% CI = 0.26-0.95); there was no association among obese men. Greater physical activity was not associated with testosterone levels, but may be associated with a reduced odds of low or low normal testosterone in non-obese men, but not in obese men.

Abstract
Hypogonadism in older men is a syndrome characterized by low serum testosterone levels and clinical symptoms often seen in hypogonadal men of younger age. These symptoms include decreased libido, erectile dysfunction, decreased vitality, decreased muscle mass, increased adiposity, depressed mood, osteopenia, and osteoporosis. Hypogonadism is a common disorder in aging men with a significant percentage of men over 60 years of age having serum testosterone levels below the lower limits of young male adults. There are a variety of testosterone formulations available for treatment of hypogonadism. Data from many small studies indicate that testosterone therapy offers several potential benefits to older hypogonadal men. A large multicenter NIH supported double blind, placebo controlled study is ongoing, and this study should greatly enhance the information available on efficacy and side effects of treatment. While safety data is available across many age groups, there are still unresolved concerns associated with testosterone therapy. We have reviewed the diagnostic methods as well as benefits and risks of testosterone replacement therapy for hypogonadism in aging men.

Abstract
Late-onset hypogonadism is a clinical and biological syndrome associated with advancing age and characterized by typical symptoms and a deficiency in serum testosterone levels. It is a common condition but often underdiagnosed and undertreated. The main symptoms of hypogonadism are reduced libido/erectile dysfunction, reduced muscle mass and strength, increased adiposity, osteoporosis/low bone mass, depressed mood, and fatigue. Testosterone replacement therapy is only warranted in the presence of both clinical symptoms suggesting hormone deficiency and decreased hormone levels. It improves libido and sexual function, bone density, muscle mass, body composition, mood, erythropoiesis, cognition, quality of life, and cardiovascular disease.

Abstract
Increased longevity and population aging will increase the number of men with late-onset hypogonadism, a common condition that is often under diagnosed and under treated. The indication of testosterone replacement therapy (TRT) treatment requires the presence of low testosterone level and symptoms and signs of hypogonadism. Although there is a lack of large-scale, long-term studies assessing the benefits and risks of TRT in men with hypogonadism, reports indicate that TRT may produce a wide range of benefits that include improvement in libido and sexual function, bone density, muscle mass, body composition, mood, erythropoiesis, cognition, quality of life, and cardiovascular disease. Perhaps the most controversial area is the issue of risk, especially the possible stimulation of prostate cancer by testosterone, even though there is no evidence to support this risk. Other possible risks include worsening symptoms of benign prostatic hypertrophy, liver toxicity, hyperviscosity, erythrocytosis, worsening untreated sleep apnea, or severe heart failure. Despite this controversy, testosterone supplementation in the United States has increased substantially in the past several years. The physician should discuss with the patient the potential benefits and risks of TRT. This review discusses the benefits and risks of TRT.

Abstract
Many signs of aging, such as sexual dysfunction, visceral obesity, impaired bone and muscle strength, bear a close resemblance to features of hypogonadism in younger men. The statistical decline of serum testosterone in aging men is solidly documented. It has been presumed that the above features of aging are related to the concurrent decline of androgens, and that correction of the lower-than-normal circulating levels of testosterone will lead to improvement of symptoms of aging. But in essence, the pivotal question whether the age-related decline of testosterone must be viewed as hypogonadism, in the best case reversed by testosterone treatment, has not been definitively resolved. Studies in elderly men with lower-than-normal testosterone report improvement of features of the metabolic syndrome, bone mineral density, of mood and of sexual functioning. But as yet there is no definitive proof of the beneficial effects of restoring testosterone levels to normal in elderly men on clinical parameters. Few of these studies meet as yet rigorous standards of scientific enquiry: double-blind, placebo-controlled design of the study. The above applies also to the assessment of safety of testosterone administration to elderly men. There is so far no convincing evidence that testosterone is a main factor in the development of prostate cancer in elderly men and guidelines for monitoring the development of prostate disease have been developed. It is of note that there are presently no long-term safety data with regard to the prostate. Polycythemia is another potential complication of testosterone treatment. It is dose dependent and can be managed with dose adjustment.

Abstract
Background Over the past two decades, there has been a substantial growth in the body of literature on frailty in older persons. However, there is no consensus on its definition or the criteria used to identify frailty. In response to this lack of consensus, the Canadian Initiative on Frailty and Aging carried out a set of systematic reviews of the literature in ten areas of frailty research: biological basis; social basis; prevalence; risk factors; impact; identification; prevention and management; environment and technology; health services; health and social policy. This paper describes the methodology that was developed for the systematic reviews. Methods A Central Coordination Group (CCG) was responsible for developing the methodology. This involved the development of search strategies and keywords, article selection processes, quality assessment tools, and guidelines for the synthesis of results. Each review was conducted by two experts in the content area, with the assistance of methodologists and statisticians from the CCG. Results Conducting a series of systematic literature reviews involving a range of disciplines on a concept that does not have a universally accepted definition posed several conceptual and methodological challenges. The most important conceptual challenge was determining what would qualify as literature on frailty. The methodological challenges arose from our goal of structuring a consistent methodology for reviewing literature from diverse fields of research. At the outset, certain methodological guidelines were deemed essential to ensure the validity of all the reviews. Nevertheless, it was equally important to permit flexibility in the application of the proposed methodology to capture the essence of frailty research within the given fields. Conclusion The results of these reviews allowed us to establish the status of current knowledge on frailty and promote collaboration between disciplines. Conducting systematic literature reviews in health science that involve multiple disciplines is a mechanism to facilitate interdisciplinary collaboration and a more integrated understanding of health. This initiative highlighted the need for further methodological development in the performance of multidisciplinary systematic reviews.

Abstract
OBJECTIVES Anabolic-androgenic steroids such as Nandrolone phenpropionate (NP) dramatically improve the tolerance to acute stress conditions, strength, and subsequently the quality of life in elderly men. We hypothesize that preoperative pulse-dose supraphysiological NP administration might improve the early morbid symptoms in older patients undergoing open prostatectomy. METHODS From 2005 to 2006, 54 patients with a mean age of 70 years, diagnosed as benign prostatic hyperplasia and hospitalized for open prostatectomy were enrolled in the study. They were randomly selected to receive preoperative supraphysiological NP (100 mg, intramuscularly, pulse-dose) or sesame oil placebo, prospectively. Early postoperative morbid symptoms including subjective urinary symptoms (dysuria, bladder retention sensation), incision site pain and general satisfaction of their current urinary condition were assessed by a 6-point scale, self-administrated questionnaire at 24 and 48 h, postoperatively. The sex hormone binding globulin and the testosterone levels were also measured. RESULTS The 24-h postoperative symptoms were significantly reduced in the NP group compared to the placebo (6.18 +/- 2.81 versus 9.77 +/- 2.15; P < 0.001). The postoperative symptoms were reported to have a decline in the 48 h following operation, though was calculated to be statistically insignificant (4.48 +/- 2.32 versus 5.55 +/- 1.84; P = 0.06). There was no complication attributed to NP therapy. CONCLUSIONS The data supported the hypothesis that the preoperative anabolic steroid supplements (such as NP) could result in a better postoperative endurance in elderly men undergoing open prostatectomy. Further studies, longer and repeated pulse injections in a larger number of older men are mandatory to prove the claim.

Abstract
The decline, with aging, in serum concentrations of biologically active forms of testosterone in men is an indisputable fact and some men will eventually develop symptoms of late-onset hypogonadism (LOH) with its clinical consequences. LOH reduces quality of life and may pose important risk factors for frailty, changes in body composition, cardiovascular disease, sexual dysfunction and osteoporosis. Testosterone supplementation in cases of LOH will restore serum testosterone levels into the physiologic range; will restore metabolic parameters to the eugonadal state, increase muscle mass, strength, and function; maintaine or improve BMD reducing fracture risk; will improve neuropsychological function (cognition and mood); libido and sexual functioning; and enhance quality of life. The ultimate goals, however, are to maintain or regain a high quality of life, to reduce disability, to compress major illnesses into a narrow age range and to add life to years. To achieve these goals men must also adjust their lifestyle to optimize dietary habits, as well as to exercise and to abstain from smoking life-long. Monitoring these patients is a shared responsibility that cannot be taken lightly. The physician must emphasize to the patient the need for periodic evaluations and the patient must agree to comply with these requirements. The physician's evaluation should include an assessment of the clinical response and monitoring must be tailored to the indications and individual needs of the patient.

Abstract
RATIONALE Dehydroepiandrosterone (DHEA) has been reported to enhance cognition in rodents, although there are inconsistent findings in humans. OBJECTIVES The aim of this study was to investigate the effects of DHEA administration in healthy young men on episodic memory and its neural correlates utilising an event-related potential (ERP) technique. METHODS Twenty-four healthy young men were treated with a 7-day course of oral DHEA (150 mg b.d.) or placebo in a double blind, random, crossover and balanced order design. Subjective mood and memory were measured using visual analogue scales (VASs). Cortisol concentrations were measured in saliva samples. ERPs were recorded during retrieval in an episodic memory test. Low-resolution brain electromagnetic tomography (LORETA) was used to identify brain regions involved in the cognitive task. RESULTS DHEA administration led to a reduction in evening cortisol concentrations and improved VAS mood and memory. Recollection accuracy in the episodic memory test was significantly improved following DHEA administration. LORETA revealed significant hippocampal activation associated with successful episodic memory retrieval following placebo. DHEA modified ERPs associated with retrieval and led to a trend towards an early differential activation of the anterior cingulate cortex (ACC). CONCLUSIONS DHEA treatment improved memory recollection and mood and decreased trough cortisol levels. The effect of DHEA appears to be via neuronal recruitment of the steroid sensitive ACC that may be involved in pre-hippocampal memory processing. These findings are distinctive, being the first to show such beneficial effects of DHEA on memory in healthy young men.

Abstract
In ageing men testosterone levels decline, while cognitive function, muscle and bone mass, sexual hair growth, libido and sexual activity decline and the risk of cardiovascular diseases increase. We set up a double-blind, randomized placebo-controlled trial to investigate the effects of testosterone supplementation on functional mobility, quality of life, body composition, cognitive function, vascular function and risk factors, and bone mineral density in older hypogonadal men. We recruited 237 men with serum testosterone levels below 13.7 nmol/L and ages 60–80 years. They were randomized to either four capsules of 40 mg testosterone undecanoate (TU) or placebo daily for 26 weeks. Primary endpoints are functional mobility and quality of life. Secondary endpoints are body composition, cognitive function, aortic stiffness and cardiovascular risk factors and bone mineral density. Effects on prostate, liver and hematological parameters will be studied with respect to safety. Measure of effect will be the difference in change from baseline visit to final visit between TU and placebo. We will study whether the effect of TU differs across subgroups of baseline waist girth (< 100 cm vs. ≥ 100 cm; testosterone level (<12 versus ≥ 12 nmol/L), age (< median versus ≥ median), and level of outcome under study (< median versus ≥ median). At baseline, mean age, BMI and testosterone levels were 67 years, 27 kg/m2 and 10.72 nmol/L, respectively.

Abstract
Testosterone depletion is a normal consequence of aging in men that is associated with senescent effects in androgen- responsive tissues. We discuss new evidence that one consequence of testosterone depletion in men is an increased risk for the development of Alzheimer's disease (AD). Furthermore, we discuss two candidate mechanisms by which testosterone may affect AD pathogenesis. First, testosterone has been identified as an endogenous regulator of beta-amyloid, a protein that abnormally accumulates in AD brain and is implicated as a causal factor in the disease. Second, findings from several different paradigms indicate that testosterone has both neurotrophic and neuroprotective functions. These new findings support the clinical evaluation of androgen-based therapies for the prevention and treatment of AD.

Abstract
Aging in men is associated with a progressive decline in the production of several hormones, including androgens. The extent to which an age-dependent decline in androgen levels lead to health problems or can affect quality of life remains under debate. Clinical results on replacement therapy do not yet provide a definitive clue on the benefit/risk balance. A sexual dimorphism of the immune system is well established, and the differences between female and male immune responses under normal, as well as pathological, conditions are generally attributed to the influence of estrogens, progestins, and androgens. The suppressive effects of male sex hormones on immune functions have been observed in a wide variety of disease processes and appear to be testosterone-mediated. Endogenous testosterone inhibits skin wound healing response in males and is associated with an enhanced inflammatory response. Although there are no known gender-related differences in permeability barrier function in adults, estrogens accelerates--whereas testosterone retards--barrier development in fetal skin, and male fetuses demonstrate slower barrier development than female littermates.

Abstract
OBJECTIVES To evaluate whether low testosterone levels are associated with greater depression or poorer function in a geriatric rehabilitation unit. DESIGN Retrospective review. SETTING Geriatric rehabilitation unit. MEASUREMENTS Low testosterone levels were defined as total testosterone of 3.0 ng/mL or less or free testosterone of 9.0 pg/mL or less. Age, ethnicity, weight, depression, ambulation, length of rehabilitation, and 6-month rehospitalization and mortality rates were obtained. Overall illness severity was determined using the Cumulative Illness Rating Scale for Geriatrics. RESULTS Low testosterone levels were present in 29 of 44 (65.9%) men. There were no significant differences between men with low and normal testosterone levels in ethnicity, age, weight, depression, and overall illness severity. Lower testosterone levels were correlated with decreased ability to ambulate and transfer (Spearman P>.34; P<.05). There were no significant differences between men with low and normal testosterone in length of stay on the rehabilitation unit (mean+/-standard deviation= 19.6+/-11.6 vs 17.7+/-17.5 days, P=.68) or rehospitalization rates (41.4% vs 26.7%; P=.34). Men with low testosterone had a trend toward increased 6-month mortality (31.0% vs 6.7%; chi(2)=3.3, P=.07) and shorter survival time (log rank=3.2; df 1, P=.07). After entering testosterone and variables with potential prognostic significance for mortality in a stepwise manner in a Cox regression analysis, there was a significant mortality risk associated with low testosterone (hazard ratio=27.9, 95% confidence interval=2.0-384.0; P=.01). CONCLUSION Low testosterone levels were correlated with decreased physical function and increased risk for 6-month mortality. Prospective studies with larger sample sizes and better standardized testosterone measures are needed to confirm these findings.

Abstract
Physicians are seeing an increasing number of older male patients with chronic diseases and conditions. However, the potential relevance of low levels of circulating endogenous androgens in connection with these diseases and conditions is generally poorly understood. Research findings have suggested that androgens play a distinct role in bone metabolism, body composition such as muscle and fat mass and fat distribution, cognitive functioning, mood and well being. The aim of this paper is to summarize the currently available data on the association between endogenous androgens and the intermediate or clinically manifest indicators of chronic conditions in men that might contribute to the phenomenon "frailty". The evidence that reductions in endogenous androgens play a role in age-related health problems is circumstantial. Therefore, large-scale randomized trials are needed to establish whether aging males with low serum androgen levels benefit from androgen supplementation.
