Book Synopsis Glucocorticoid-induced Osteoporosis by : Andrea Giustina
Download or read book Glucocorticoid-induced Osteoporosis written by Andrea Giustina and published by Karger Medical and Scientific Publishers. This book was released on 2002 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: Osteoporosis is one of the most clinically relevant disabling chronic disease encountered in clinical practice. A common cause of osteoporosis is glucocorticoid excess, as glucocorticoids may increase bone resorption, inhibit bone formation, have indirect actions on bone by decreasing intestinal calcium absorption and induce hypercalciuria. This book presents a comprehensive overview of the effects of glucocorticoids on bone metabolism and structure and on the diagnosis and treatment of glucocorticoid-induced osteoporosis. It aims at providing updated information on the pathogenesis, diagnosis and treatment of this often dramatic complication of glucocorticoid excess. Being one of the few publications completely devoted to glucocorticoid-induced osteoporosis it will heighten the awareness of specialists who prescribe glucocorticoids of the clinical relevance of this treatment complication. 'Glucocorticoid-Induced Osteoporosis' is addressed to clinical experts as well as to general practitioners who will both benefit from the comprehensive and integrative view of the management of patients exposed to glucocorticoids.

Watson and published by . This book was released on 2001-04-01 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Osteoporosis is a condition involving decreased bone mineral density (BMD) and increased fragility of the skeletal system. Osteoporosis affects ^75 million individuals in the United States, Europe, and Japan. In the United States alone, hip fractures affect 500,000 individuals per year, and annual healthcare costs for osteoporotic fractures are approximately $l4 billion. A high peak BMD can prevent or delay the onset of osteoporosis and its complications. Exercise and diet may affect peak BMD by as much as 20 to 40% each and have been identified as the two most important controllable factors determining BMD. The current study investigated the effect of a calcium, vitamin D, and vitamin K supplement combination during initial military cadet exercise training on: BMD, stress fracture occurrence, hormones associated with BMD, and biochemical markers of bone turnover. Significant changes in BMD, either between the supplemented group or the unsupplemented group or across time for both groups were not found. The majority of participants (n = 22) had unexpectedly high levels of physical activity prior to enrollment, and the initial military exercise training program included only moderate levels of activity. Therefore, the exercise stimulus to bone was likely insufficient to promote gains in BMD, regardless of the nutrient supplement status. Serum insulin-like growth factor-I and osteocalcin significantly increased over time (p
Book Synopsis The Effects of a Uniformly Weighted Exercise Suit on Biomarkers of Bone Turnover in Response to Aerobic Exercise in Postmenopausal Women with Low Bone Density by : Haley Frances Terndrup

This book was released on 2016 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current options for maintaining or slowing aging-related bone mineral density (BMD) loss in postmenopausal women primarily include pharmaceutical agents. More recently, physical activity and exercise have been suggested as highly effective, low cost alternatives. Weighted aerobic exercise, utilizing load carriage systems (LCS), is known to increase the gravitational forces impacting bone, creating a higher osteogenic stimulus than standard aerobic exercise. In response to the positive research on aerobic exercise with well-designed LCS, Dr. Lawrence Petrakis, MD, developed a unique 5.44 kg uniformly weighted exercise suit. This study aimed to examine the effects of the uniformly weighted exercise suit on serum biochemical markers of bone formation (Amino- Propeptide of Type 1 Collagen [P1NP]; Carboxy-Terminal Propeptide of Type 1 Collagen [P1CP] and resorption (Carboxy-Terminal Telopeptide of Type 1 Collagen [CTX]) in response to submaximal aerobic exercise in postmenopausal women with low bone density. Nine volunteer, sedentary to lightly active, healthy postmenopausal women (Age: 58.7±1.1 years, BMI: 28.2±1.0, BMD T-score: -1.2±0.5) participated in this within-subjects study, wherein each participant exercised under two counterbalanced conditions (aerobic exercise with [ES] or without [NS] the exercise suit). During each condition, participants walked on a treadmill at 65%-75% of their age-predicted maximum heart rate until they reached their goal caloric expenditure (400kcal). There was a seven-day washout period between sessions. Serum was processed using ELISA protocols to investigate the change in biomarker at 24 and 72 hours post exercise, relative to baseline. The results indicated, when compared to the NS condition, the ES condition elicited a greater positive change in P1CP at 24 hours (Phours following exercise (P0.05). There was no effect of condition on P1NP at any time point (P>0.05). In sum, submaximal aerobic exercise while wearing the uniformly weighted exercise suit elicited an antiresorptive effect on bone collagen resorption with a simultaneous increase in bone collagen formation 24 hours post exercise.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Female Athlete Triad (Triad), a syndrome of low energy availability, menstrual dysfunction, and low bone mineral density (BMD), affects up to 60% of exercising girls and women. As such, understanding the physiology underlying the Triad is imperative in order to identify therapeutic targets and develop effective treatment strategies to prevent long-term health detriments in afflicted women. Bone health is a major clinical outcome of concern in female athletes and exercising women with the Triad, as bone loss or suboptimal peak bone mass development may predispose women to osteoporosis and related fractures later in life. To garner a better understanding of factors contributing to bone health and to inform guidelines for treatment targets in female athletes and exercising women with the Triad, this purpose of this dissertation was 1) to assess the unique and combined effects of energy status and estrogen status on volumetric BMD (vBMD), bone geometry, and estimated bone strength in exercising women, 2) to assess the unique and combined effects of energy status and estrogen status on bone turnover in exercising women, 3) to evaluate predictors of change in bone turnover dynamics across a 12-month nutritional intervention in women with exercise-associated menstrual disturbances, and 4) to determine if bone turnover dynamics at baseline impact BMD outcomes in women with exercise-associated menstrual disturbances participating in a nutritional intervention. Key findings of the studies that made up this dissertation implicate that energy status is a main driving factor dictating vBMD, bone geometry, estimated bone strength, and bone metabolism in exercising women. The results indicate that improving energetic status will not only improve bone turnover at the cellular level, but that bone turnover favoring bone formation over bone resorption will also predict improved BMD in the following year. The findings support the guidelines put forth by the Female Athlete Triad Coalition that endorse nutritional therapy as the first line of treatment for the Triad, as low energy availability is the root cause of the clinical sequelae, including menstrual dysfunction and compromised bone health.
Book Synopsis The Effects of Plyometrics Or Resistance-training on Markers of Bone Turnover and Hormones in Men by : Robert S. Rogers

This book was released on 2009 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weight-bearing exercise positively affects bone mineral density (BMD) and bone strength, presumably by altering the balance between bone formation and resorption. The purpose of the present study was to determine the acute response of markers of bone turnover and hormones to a single-bout of resistance-training or plyometrics. Twelve recreationally active males, aged 24-63 years, participated in this partially randomized cross-over study, which included five trials: PLY (fed/fasted), RT (fed/fasted), and a no-exercise, fed control trial (CON) (n=6). Blood was drawn immediately prior to exercise (PRE), immediately following exercise (POST), and 15, 30, 60, 120 min, and 24 hr following PRE. Total testosterone (T), intact parathyroid hormone (PTH), and cortisol (COR) concentrations in serum were determined. Serum bone-specific alkaline phosphatase (BAP) (bone formation marker) and tartrate-resistant acid phosphatase, isoform 5b (TRAP5b) (bone resorption marker) were measured. The results of the present study suggest favorable changes in bone formation and bone resorption as assessed by bone turnover markers (BAP and TRAP5b) following a single-bout of RT or PLY. The decrease in PTH following plyometrics and resistance-training positively correlated with a decrease in TRAP5b, suggesting that PTH may mediate the exercise-induced changes in osteoclast activity.

This book was released on 2016 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Introduction: Young male jockeys compromise bone health by engaging in caloric restriction and high volumes of physical activity during periods of musculoskeletal growth and development. Failure to attain peak bone mass (PBM) during growth can have adverse short and long term musculoskeletal effects, with numerous studies demonstrating inferior bone health in jockey populations. However, no study to date has addressed counteracting the deleterious effects that participation in this sport has on bone health. The purpose of this six-month double-blind randomised placebo controlled trial was to examine the efficacy of 800mg calcium and 400 IU vitamin D daily supplementation on improving bone mineral properties at the tibia (weight-bearing) and radius (non-weight-bearing) using peripheral Quantitative Computed Tomography (pQCT) and blood-borne markers of bone turnover.Three inter-related studies were designed following the findings of a systematic review and meta-analysis examining the effects of calcium and vitamin D supplementation on bone mineral density in healthy males. Study one examined the effect that the protocol had on markers of bone metabolism and bone properties of the radius. Study two was designed to investigate the impact of six months supplementation on weight-bearing bone while study three further explored alterations to radial and polar cortical bone properties at the tibial mid-shaft following the clinical trial.Methods: Twenty-nine male jockeys (age=20.18 ± 3.23yrs) were originally recruited to the study with 17 completing the intervention. Bone properties at the ultra-distal (4%) and proximal (66%) radius and tibia using pQCT and serum vitamin D, Procollagen type 1 N propeptide (P1NP) and C-terminal telopeptide of type I collagen (CTx) were assessed at baseline and six months. Bone properties at the 66% tibial site were further analysed using BoneJ pQCT distribution plug-in. Polar and radial volumetric bone mineral density (vBMD) was measured in 36, ten degree cortical sectors (polar) and three concentric cortical divisions (radial). Polar distribution was further consolidated into four, 90 degree quadrants aligned to anatomical planes. Cortical mineral mass, endocortical and pericortical radii were also analysed.Results: After co-varying for height, body mass and baseline bone measurements, the analysis of co-variance (ANCOVA) results of these combined studies demonstrate that six months calcium and vitamin D supplementation stimulated a reduction in bone resorption together with significant improvements to bone material properties at the proximal tibia in the supplemented group. ANCOVA serum analysis indicated significantly higher vitamin D levels (18.1%, p=0.014) and lower CTx (ng/L) (-24.8%, p=0.011) in the supplemented group with P1NP unchanged. The supplemented group displayed greater post-intervention bone properties at the 66% proximal site with cortical content (mg·mm) 6.6% greater (p

Download or read book Monitoring Metabolic Status written by Institute of Medicine and published by National Academies Press. This book was released on 2004-08-29 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. military's concerns about the individual combat service member's ability to avoid performance degradation, in conjunction with the need to maintain both mental and physical capabilities in highly stressful situations, have led to and interest in developing methods by which commanders can monitor the status of the combat service members in the field. This report examines appropriate biological markers, monitoring technologies currently available and in need of development, and appropriate algorithms to interpret the data obtained in order to provide information for command decisions relative to the physiological "readiness" of each combat service member. More specifically, this report also provides responses to questions posed by the military relative to monitoring the metabolic regulation during prolonged, exhaustive efforts, where nutrition/hydration and repair mechanisms may be mismatched to intakes and rest, or where specific metabolic derangements are present.

Download or read book Sex Steroids and Bone written by Reinhard Ziegler and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bone is a sex hormone-dependent organ, which has important implications for current therapeutic strategies in the prevention and possible treatment of bone loss in the elderly. This book contains the proceedings of the Schering Workshop on "Sex Steroids and Bone." The various chapters by leading experts give and overall view of current knowledge on the control of bone hemostasis by sex steroids and new ideas on how this controlcould be exerted. It was also of particular concern to integrate a general survey of in vivo experimentation and histomorphometric evaluation of bone tissue. The organizers of the workshop and editors of this volume hope that it will contribute to a better understanding of the role of sex steroids in bone and thus pave the way for a better experimental approach instudying drug effects on bone with the ultimate goal of improving therapy in bone diseases.

Book Synopsis Exercise and Human Reproduction by : Diana Vaamonde
Download or read book Exercise and Human Reproduction written by Diana Vaamonde and published by Springer. This book was released on 2016-03-07 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Providing a comprehensive review of the interactions between exercise and human reproduction, this unique text focuses on both the positive and negative consequences of sport and physical activity on male and female fertility and infertility and the biological mechanisms and processes behind them. Beginning with a review of the structure and function of the male and female reproductive systems as well as fertilization and gestation, the discussion then turns to the physiology and endocrinology of sport and exercise, which is further elaborated in subsequent chapters on the impact of physical activity, hormonal changes, pathologies, and consequences of drug use for active men and women. Additional chapters address related topics, such as the impact of sport on young athletes and developing reproductive potential, physical activity and pregnancy, the use of oral contraceptives in athletes, oxidative stress, and the impact of nutritional deficiencies on athletes’ fertility, with a final chapter providing recommendations and therapeutic guidelines for exercise-related reproductive disorders. Covering everything from the fundamental principles of sports physiology and human reproductive potential to the interaction between physical exercise and the endocrinology of the reproductive system, Exercise and Human Reproduction is an authoritative resource for helping clinicians understand how the reproductive system adapts to activity and exercise and offers strategies to avoid potential harm to human reproduction.
