Osteoporosis is an unavoidable public health problem in an aging or aged society. Anti-resorptive agents (calcitonin, estrogen, and selective estrogen-receptor modulators, bisphosphonates, anti-receptor activator of nuclear factor κB ligand antibody along with calcium and vitamin D supplementations) and anabolic agents (parathyroid hormone and related peptide analogs, sclerostin inhibitors) have major roles in current treatment regimens and are used alone or in combination based on the pathological condition...

Currently, 424 million people aged between 20-79 years worldwide are diabetic. More than 25% of adults aged over 65 years in North America have Type 2 diabetes mellitus (DM). Diabetes-induced osteoporosis (DM-OS) is caused by chronic hyperglycemia, advanced glycated end products and oxidative stress. The increase in the prevalence of DM-OS has prompted researchers to develop new biological therapies for the management of DM-OS. Areas covered: This review covered the current and novel biological agents used in the management of DM-OS...

Selective androgen receptor modulators comprise compounds that bind as ligands to the androgen receptor and possess tissue-selective activities. Ideally, they show agonistic properties in anabolic target tissues, while inducing antagonistic or only weak agonistic effects in reproductive organs. Due to their myoanabolic effects, selective androgen receptor modulators are included in the list of prohibited substances and methods of the World Anti-Doping Agency. In the current investigation, the androgenic potential of RAD-140, GSK-2881078 and GLPG0492 was comparably investigated in two different in vitro bioassays...

We previously identified a novel selective androgen receptor modulator, S42, that does not stimulate prostate growth but has a beneficial effect on lipid metabolism. S42 also increased muscle weight of the levator ani in orchiectomized Sprague-Dawley rats. These findings prompted us to investigate whether S42 has a direct effect on cultured C2C12 myotubes. S42 significantly lowered expression levels of the skeletal muscle ubiquitin ligase (muscle atrophy-related gene), atrogin1 and Muscle RING-Finger Protein 1(MuRF1) in C2C12 myotubes, as determined by real time PCR...

BACKGROUND: Teriparatide, a 1-34 fragment of parathyroid hormone (PTH) that maintains most of the biological activities of PTH, has been employed since 2002 as an anabolic agent for osteoporotic individuals who are at high risk of fracture. The purpose of the present review is to provide a systematic summary and timely update on treatment with teriparatide for fracture prevention. METHODS: Electronic databases, including OVID MEDLINE, OVID Embase, and the Cochrane Library, were searched on February 9, 2018, to identify published systematic reviews and meta-analyses addressing treatment with teriparatide for fracture prevention, and A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR 2) was used to assess the quality of included studies...

Through doping, we understand the use by athletes of substances prohibited by the antidoping agencies in order to gain a competitive advantage. Since sport plays an important role in physical and mental education and in promoting international understanding and cooperation, the widespread use of doping products and methods has consequences not only on health of the athletes, but also upon the image of sport. Thus, doping in sports is forbidden for both ethical and medical reasons. Narcotics and analgesics, anabolic steroids, hormones, selective androgen receptor modulators are among the most frequently utilized substances...

INTRODUCTION: Selective androgen receptor modulators (SARMs) differentially bind to androgen receptors depending on each SARM's chemical structure. As a result, SARMs result in anabolic cellular activity while avoiding many of the side effects of currently available anabolic steroids. SARMs have been studied in the treatment of breast cancer and cachexia and have also been used as performance-enhancing agents. Here, we evaluate and summarize the current literature on SARMs. AIM: To present the background, mechanisms, current and potential clinical applications, as well as risks and benefits of SARMs...

CONTEXT: The prevalence of body image disorders and anabolic-androgenic steroid (AAS) use is increasing, despite the evidence of their serious adverse health effects and despite the passage of laws regulating their sales. Here we review the evolution of the dual emerging epidemics of body image disorders and AAS use, adverse health effects of AASs, and the need for an integrated health policy and regulatory response. EVIDENCE ACQUISITION: We searched for studies published prior to June 2018...

Sarcopenia is defined as a combination of low muscle mass with low muscle function. The term was first used to designate the loss of muscle mass and performance associated with aging. Now, recognized causes of sarcopenia also include chronic disease, a physically inactive lifestyle, loss of mobility, and malnutrition. Sarcopenia should be differentiated from cachexia, which is characterized not only by low muscle mass but also by weight loss and anorexia. Sarcopenia results from complex and interdependent pathophysiological mechanisms that include aging, physical inactivity, neuromuscular compromise, resistance to postprandial anabolism, insulin resistance, lipotoxicity, endocrine factors, oxidative stress, mitochondrial dysfunction, and inflammation...

PURPOSE OF REVIEW: Hypogonadism and the treatment of low testosterone is increasingly a subject of medical inquiry and controversy. The few treatments that are FDA-approved such as testosterone topicals, injections, and pellets create significant demand from patients for treatments with more convenient means of administration, fewer adverse effects, and the ability to maintain male fertility. Off-label drugs are in abundant use for low testosterone, including selective estrogen receptor modulators, gonadotropins, and aromatase inhibitors...

Identification of patients at risk for fragility fractures is the first important step in the management of osteoporosis. Bisphosphonates have been the mainstay of treatment for decades, whereas denosumab and selective oestrogen receptor modulators are other available licensed antiresorptive drugs. Currently teriparatide is the only approved anabolic agent in Europe, while abaloparatide and romosozumab are awaiting approval and might be available in the near future. For bisphosphonates, current guidance suggests an initial treatment course of 3-5 years and more prolonged treatment should be pursued in patients with higher fracture risk...

Antiestrogenic compounds such as tamoxifen, toremifen and chlomifen are used illegally by athletes to minimize physical impacts such as gynecomastia resulting from the secondary effects of anabolic androgenic steroids, used to increase athletic efficiency unlawfully. The use of these compounds is banned by the World Anti-Doping Agency (WADA) and controls are made through analytical methodologies such as HPLC-MS/MS, which do not fulfil the sample throughput requirements. Moreover, compounds such as tamoxifen are also used to treat hormone receptor-positive breast cancer (ER + )...

Although the use of nutritional supplements by adult athletes has been extensively studied, information on supplements consumption by adolescent athletes is still limited. The present study reports on the use of nutritional supplements contaminated with banned doping substances among 170 recreational adolescent athletes from eleven, randomly selected, gym centres, in Athens, Greece. Nutritional supplements consumption was reported by almost 60% of the study population, with proteins/amino acids and vitamins being the most popular...

PURPOSE OF REVIEW: Osteoporosis guidelines do not usually provide specific recommendations regarding what medication is most appropriate for individual patients. Generic oral bisphosphonates are often considered first-line treatment for osteoporosis, but treatment duration is limited, based on potential long-term safety concerns, and there is no consensus about what to do after 5 years. There are no recommendations concerning long-term management of osteoporosis over 30 or more years of postmenopausal life...

Except for the essential amino acids (AAs), much of the focus on adequate dietary protein intake has been on total nitrogen and caloric intake rather than AA composition. Recent data, however, demonstrate that "amino-acid sensing" can occur through either intracellular or extracellular nutrient-sensing mechanisms. In particular, members of the class 3 G-protein coupled receptor family, like the calcium-sensing receptor are known to preferentially bind specific AAs, which then modulate receptor activation by calcium ions and thus potentially impact bone turnover...

Androgens are key regulators that play a critical role in the male reproductive system and have anabolic effects on bone mineral density and skeletal muscle mass. We have previously reported that YK11 is a novel selective androgen receptor modulator (SARM) and induces myogenic differentiation and selective gene regulation. In this study, we show that treatment of YK11 and dihydrotestosterone (DHT) accelerated cell proliferation and mineralization in MC3T3-E1 mouse osteoblast cells. Further, YK11-treated cells increased osteoblast specific differentiation markers, such as osteoprotegerin and osteocalcin, compared to untreated cells...

The detection of drugs in human hair samples has been performed by laboratories around the world for many years and the matrix is popular in disciplines, such as workplace drug testing. To date, however, hair has not become a routinely utilised matrix in sports drug detection. The analysis of hair samples offers several potential advantages to doping control laboratories, not least of which are the greatly extended detection window and the ease of sample collection and storage. This article describes the development, validation, and utilisation of a sensitive ultra-high performance liquid chromatography-triple quadrupole mass spectrometry (UHPLC-MS/MS) method for the detection of 50 compounds...

Cancer cachexia is a syndrome that impairs the quality of life and overall survival of patients, and thus the effectiveness of anticancer agents. There are no effective therapies for cancer cachexia due to the complexity of the syndrome, and insufficient knowledge of its pathogenesis results in difficulty establishing appropriate animal models. Previously, promising results have been obtained in clinical trials using novel agents including the ghrelin receptor agonist anamorelin, and the selective androgen receptor modulator (SARM) enobosarm to treat cachexia in patients with cancer...
