Brown AM, Ganjayi MS, Baumann CW. RAD140 (Testolone) negatively impacts skeletal muscle adaptation, frailty status and mortality risk in female mice. Clin Exp Pharmacol Physiol 2023; 50:973-983. [PMID: 37758180 DOI: 10.1111/1440-1681.13824] [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: 05/12/2023] [Revised: 07/25/2023] [Accepted: 08/28/2023] [Indexed: 10/03/2023]
Abstract
RAD140 is a selective androgen receptor modulator that produces anabolic effects within skeletal muscle. Thus, RAD140 may be effective at treating sarcopenia. No long-term studies have investigated how RAD140 influences strength in ageing muscle. This study aimed to determine how 10 weeks of RAD140 supplementation impacts strength, recovery from exercise, and overall health in ageing mice. Young and adult females were assigned to receive RAD140 (5 mg/kg) or a control solution. Dorsiflexor muscles were exposed to repeated bouts of eccentric contractions, and torque was measured before and after each bout. Adaptive potential and strength gains were calculated to assess the efficacy of RAD140 in muscle, while frailty status and mortality risk were used to measure health span. Supplementation of RAD140 increased frailty status and mortality risk in the young and adult treated groups compared to the controls (p ≤ 0.042). RAD140 decreased adaptive potential in young (p = 0.040) but not adult mice (p = 0.688). Torque did not differ between groups after 2-3 weeks of recovery (p ≥ 0.135). In conclusion, long-term RAD140 supplementation reduced indices of overall health and failed to improve strength in female mice, suggesting that RAD140 (at a 5mg/kg dosage) may be more detrimental than beneficial in delaying or preventing sarcopenia.

Abstract
PURPOSE To understand the systemic effect of major spine surgery, we investigated stress, anabolic and catabolic hormonal levels and their association with interleukin 6 (IL-6) in patients undergoing elective lumbar spine fusion surgery. METHODS Blood samples were collected preoperatively, and at 1, 3, 42, 90 days postoperatively (POD) from 49 patients who underwent elective lumbar spine fusion surgery. RESULTS Serum concentration of cortisol was below the preoperative value at POD 1 but did not differ from the baseline values thereafter. Adrenocorticotropic hormone (ACTH) decreased at PODs 1 and 3. Testosterone decreased at PODs 1 and 3 in men, and at POD 3 in women. Sex hormone-binding globulin decreased at PODs 1 and 3 in both genders. No changes were observed in free testosterone or growth hormone concentrations. Insulin-like growth factor 1 increased significantly above the preoperative level at PODs 42 and 90 in women, and at POD 42 in men. IL-6 was significantly elevated at PODs 1 and 3. Increases in IL-6 from the preoperative level to POD 1 correlated significantly with decreases of cortisol at POD 1 but not with ACTH. CONCLUSIONS There were only short-term stress hormonal changes after elective lumbar spine fusion surgery. Cortisol changes after elective lumbar spine surgery are transient and might be partly cytokine induced and non-ACTH driven since there was association between cortisol and IL-6 but not with ACTH and IL-6.

J Am Acad Orthop Surg 2023; 31:581-588. [PMID: 36745691 DOI: 10.5435/jaaos-d-22-00554] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2022] [Accepted: 12/29/2022] [Indexed: 02/08/2023] Open
Abstract
INTRODUCTION The purpose of this study was to evaluate rates of rotator cuff tears (RCTs), repairs (RCRs), and revision RCR in patients who were prescribed testosterone replacement therapy (TRT) and compare these patients with a control group. METHODS The PearlDiver database was queried for patients who were prescribed testosterone for at least 90 days between 2011 and 2018 to evaluate the incidence of RCTs in this population. A second analysis evaluated patients who sustained RCTs using International Classification of Diseases, 9th/10th codes to evaluate these patients for rates of RCR and revision RCR. Chi square analysis and multivariate regression analyses were used to compare rates of RCTs, RCR, and subsequent or revision RCR between the testosterone and control groups, with a P -value of 0.05 representing statistical significance. RESULTS A total of 673,862 patients with RCT were included for analysis, and 9,168 of these patients were prescribed testosterone for at least 90 days before their RCT. The TRT group had a 3.6 times greater risk of sustaining an RCT (1.14% versus 0.19%; adjusted odds ratio (OR) 3.57; 95% confidence interval (CI) 3.57 to 3.96). A 1.6 times greater rate of RCR was observed in the TRT cohort (TRT, 46.4% RCR rate and control, 34.0% RCR rate; adjusted OR 1.60; 95% CI 1.54 to 1.67). The TRT cohort had a 26.7 times greater risk of undergoing a subsequent RCR, irrespective of laterality, within 1 year of undergoing a primary RCR when compared with the control group (TRT, 47.1% and control, 4.0%; adjusted OR 26.4; 95% CI 25.0 to 27.9, P < 0.001). CONCLUSIONS There is increased risk of RCTs, RCRs, and subsequent RCRs in patients prescribed testosterone. This finding may represent a musculoskeletal consequence of TRT and is important for patients and clinicians to understand. Additional research into the science of tendon injury in the setting of exogenous anabolic steroids remains of interest. LEVEL OF EVIDENCE Level Ⅲ, retrospective cohort study.

Abstract
Despite the well-documented effects of testosterone and its synthetic derivatives—collectively termed anabolic androgenic steroids (AASs)—on the musculoskeletal system, the therapeutic use of these agents has received limited investigation within the field of orthopaedic surgery. In the last 2 decades, preclinical and clinical research has started to identify promising applications of the short-term use of AASs in the perioperative period. There is evidence to suggest that AASs may improve postoperative recovery after anterior cruciate ligament reconstruction and total joint arthroplasty. In addition, AASs may augment the biological healing environment in specific clinical scenarios including muscle injury, fracture repair, and rotator cuff repair. Current literature fails to present strong evidence for or against the use of AASs in orthopaedics, but there is continuous research on this topic. The purpose of this study was to provide a comprehensive overview of the current status of AAS applications in orthopaedic surgery, with an emphasis on preclinical data, clinical studies, and future directions.

Abstract
Sarcopenia, characterized by the excessive loss of skeletal muscle mass, strength, and function, is associated with the overall poor muscle performance status of the elderly, and occurs more frequently in those with chronic diseases. The causes of sarcopenia are multifactorial due to the inherent relationship between muscles and molecular mechanisms, such as mitochondrial function, inflammatory pathways, and circulating hormones. Age-related changes in sex steroid hormone concentrations, including testosterone, estrogen, progesterone, and their precursors and derivatives, are an important aspect of the pathogenesis of sarcopenia. In this review, we provide an understanding of the treatment of sarcopenia through the regulation of sex steroid hormones. The potential benefits and future research emphasis of each sex steroid hormone therapeutic intervention (testosterone, SARMs, estrogen, SERMs, DHEA, and progesterone) for sarcopenia are discussed. Enhanced understanding of the role of sex steroid hormones in the treatment for sarcopenia could lead to the development of hormone therapeutic approaches in combination with specific exercise and nutrition regimens.

Abstract
BACKGROUND Despite being a relatively common problem among aging men, hypogonadism has not been previously studied as a potential risk factor for postoperative complications following total hip arthroplasty (THA). METHODS In total, 3903 male patients with a diagnosis of hypogonadism who underwent primary THA from 2006 to 2012 were identified using a national insurance database and compared to 20:1 matched male controls using a logistic regression analysis. RESULTS Hypogonadism was associated with an increased risk of major medical complications (odds ratio [OR] 1.24, P = .022), urinary tract infection (OR 1.43, P < .001), wound complications (OR 1.33, P = .011), deep vein thrombosis (OR 1.64, P < .001), emergency room visit (OR 1.24, P < .001), readmission (OR 1.14, P = .015), periprosthetic joint infection (OR 1.37 and 1.43, P < .05), dislocation (OR 1.51 and 1.48, P < .001), and revision (OR 1.54 and 1.56, P < .001) following THA. A preoperative diagnosis of hypogonadism was associated with increased total reimbursement and charges by $390 (P < .001) and $4514 (P < .001), respectively. CONCLUSION The diagnosis of hypogonadism is associated with an elevated risk of postoperative complications and increased cost of care following primary THA. Data from this study should influence the discussion between the patient and the provider prior to undergoing joint replacement and serve as the basis for further research.

Abstract
Testosterone is an archetypal androgenic-anabolic steroid (AAS), while its exogenous administration is considered to be the gold standard for the treatment of male hypogonadism. The benefits are not due to its intrinsic nature alone but are due to the result of its interactions with the androgen receptor (AR). As the management of hypogonadism continues to advance into the modern era, it would be preferable for modern andrologists to have multiple tools at their disposal to influence AR activity. Nandrolone, or 19-nortestosterone, is one such compound. In the following review of the literature, we examine the history, pharmacology, and clinical applications of this medication. We also present the results of our novel pilot study examining the favorable effects of nandrolone on joint pain for hypogonadal men.

Abstract
BACKGROUND Research regarding the impact of hypogonadism following primary total knee arthroplasty (TKA) is limited. Therefore, the purpose of this study is to investigate whether patients with hypogonadism undergoing primary TKA are at increased odds of (1) medical complications, (2) revisions, (3) in-hospital lengths of stay (LOSs), and (4) cost of care. METHODS A Humana patient population consisting of 8 million lives was retrospectively analyzed from 2007 to 2017 using International Classification of Disease, 9th Revision codes. Patients were filtered by male gender and patients with hypogonadism were matched to controls in a 1:4 ratio according to age and medical comorbidities. The query yielded 8393 patients with (n = 1681) and without (6712) hypogonadism undergoing primary TKA. Primary outcomes analyzed included medical complications, revision rates, in-hospital LOS, and cost of care. Logistic regression analysis was used to calculate odds ratios (OR) of 90-day medical complications and 2-year revisions. Welch's t-test was used to test for significance in LOS and cost of care between cohorts. A P-value less than .05 was considered statistically significant. RESULTS Hypogonadal patients undergoing primary TKA were found to have increased incidence and odds (9.45% vs 4.67%; OR 2.12, P < .0001) of developing 90-day medical complications. Hypogonadal patients undergoing primary TKA were found to have a greater incidence and odds (3.99% vs 2.80%; OR 1.89, P < .0001) of 2-year revisions. Hypogonadal patients had a 6.11% longer LOS (3.47 vs 3.27 days, P = .02) compared to controls, and incurred greater 90-day costs ($15,564.31 vs $14,856.69, P = .018) compared to controls. CONCLUSION This analysis of over 1600 patients demonstrates that patients with hypogonadism undergoing primary TKA have greater odds of postoperative medical complications, revisions, increased LOS, and cost of care.

Abstract
OBJECTIVES For many people with advanced osteoarthritis, total knee replacement (TKR) is an effective treatment for relieving pain and improving function. Features of perioperative care may be associated with the adverse event of chronic pain 6 months or longer after surgery; effects may be direct, for example, through nerve damage or surgical complications, or indirect through adverse events. This systematic review aims to evaluate whether non-surgical perioperative interventions prevent long-term pain after TKR. METHODS We conducted a systematic review of perioperative interventions for adults with osteoarthritis receiving primary TKR evaluated in a randomised controlled trial (RCT). We searched The Cochrane Library, MEDLINE, Embase, PsycINFO and CINAHL until February 2018. After screening, two reviewers evaluated articles. Studies at low risk of bias according to the Cochrane tool were included. INTERVENTIONS Perioperative non-surgical interventions; control receiving no intervention or alternative treatment. PRIMARY AND SECONDARY OUTCOME MEASURES Pain or score with pain component assessed at 6 months or longer postoperative. RESULTS 44 RCTs at low risk of bias assessed long-term pain. Intervention heterogeneity precluded meta-analysis and definitive statements on effectiveness. Good-quality research provided generally weak evidence for small reductions in long-term pain with local infiltration analgesia (three studies), ketamine infusion (one study), pregabalin (one study) and supported early discharge (one study) compared with no intervention. For electric muscle stimulation (two studies), anabolic steroids (one study) and walking training (one study) there was a suggestion of more clinically important benefit. No concerns relating to long-term adverse events were reported. For a range of treatments there was no evidence linking them with unfavourable pain outcomes. CONCLUSIONS To prevent chronic pain after TKR, several perioperative interventions show benefits and merit further research. Good-quality studies assessing long-term pain after perioperative interventions are feasible and necessary to ensure that patients with osteoarthritis achieve good long-term outcomes after TKR.

Nandrolone decanoate administration does not attenuate muscle atrophy during a short period of disuse. PLoS One 2019; 14:e0210823.

Abstract
BACKGROUND A few days of bed rest or immobilization following injury, disease, or surgery can lead to considerable loss of skeletal muscle mass and strength. It has been speculated that such short, successive periods of muscle disuse may be largely responsible for the age-related loss of muscle mass throughout the lifespan. OBJECTIVE To assess whether a single intramuscular injection of nandrolone decanoate prior to immobilization can attenuate the loss of muscle mass and strength in vivo in humans. DESIGN, SETTING AND PARTICIPANTS Thirty healthy (22 ± 1 years) men were subjected to 7 days of one-legged knee immobilization by means of a full leg cast with (NAD, n = 15) or without (CON, n = 15) prior intramuscular nandrolone decanoate injection (200 mg). MEASURES Before and immediately after immobilization, quadriceps muscle cross-sectional area (CSA) (by means of single-slice computed tomography (CT) scans of the upper leg) and one-legged knee extension strength (one-repetition maximum [1-RM]) were assessed for both legs. Furthermore, muscle biopsies from the immobilized leg were taken before and after immobilization to assess type I and type II muscle fiber cross-sectional area. RESULTS Quadriceps muscle CSA decreased during immobilization in both CON and NAD (-6 ± 1% and -6 ± 1%, respectively; main effect of time P<0.01), with no differences between the groups (time × treatment interaction, P = 0.59). Leg muscle strength declined following immobilization (-6 ± 2% in CON and -7 ± 3% in NAD; main effect of time, P<0.05), with no differences between groups (time × treatment interaction, P = 0.55). CONCLUSIONS This is the first study to report that nandrolone decanoate administration does not preserve skeletal muscle mass and strength during a short period of leg immobilization in vivo in humans.

Wu BW, Berger M, Sum JC, Hatch GF, Schroeder ET. Randomized control trial to evaluate the effects of acute testosterone administration in men on muscle mass, strength, and physical function following ACL reconstructive surgery: rationale, design, methods. BMC Surg 2014; 14:102.

Abstract
Background The anterior cruciate ligament (ACL) is one of four major ligaments in the knee that provide stability during physical activity. A tear in the ACL is characterized by joint instability that leads to decreased activity, knee dysfunction, reduced quality of life and a loss of muscle mass and strength. While rehabilitation is the standard-of-care for return to daily function, additional surgical reconstruction can provide individuals with an opportunity to return to sports and strenuous physical activity. Over 200,000 ACL reconstructions are performed in the United States each year, and rehabilitation following surgery is slow and expensive. One possible method to improve the recovery process is the use of intramuscular testosterone, which has been shown to increase muscle mass and strength independent of exercise. With short-term use of supraphysiologic doses of testosterone, we hope to reduce loss of muscle mass and strength and minimize loss of physical function following ACL reconstruction compared to standard-of-care alone. Methods/design This study is a double-blinded randomized control trial. Men 18–50 years of age, scheduled for ACL reconstruction are randomized into two groups. Participants randomized to the testosterone group receive intramuscular testosterone administration once per week for 8 weeks starting 2 weeks prior to surgery. Participants randomized to the control group receive a saline placebo intramuscularly instead of testosterone. Lean mass, muscle strength and physical function are measured at 5 time points: 2 weeks pre-surgery, 1 day pre-surgery, and 6, 12, 24 weeks post-surgery. Both groups follow standard-of-care rehabilitation protocol. Discussion We believe that testosterone therapy will help reduce the loss of muscle mass and strength experienced after ACL injury and reconstruction. Hopefully this will provide a way to shorten the rehabilitation necessary following ACL reconstruction. If successful, testosterone therapy may also be used for other injuries involving trauma and muscle atrophy. Trial registration NTC01595581, Registration: May 8, 2012

Abstract
Background. Recovery from peripheral nerve repair is frequently incomplete. Hence drugs that enhance nerve regeneration are needed clinically. Objectives. To study the effects of nandrolone decanoate in a model of deficient reinnervation in the rat. Methods. In 40 rats, a 40-mm segment of the left median nerve was removed and interposed between the stumps of a sectioned right median nerve. Starting 7 days after nerve grafting and continuing over a 6-month period, we administered nandrolone at a dose of 5 mg/kg/wk to half the rats (n = 20). All rats were assessed behaviorally for grasp function and nociceptive recovery for up to 6 months. At final assessment, reinnervated muscles were tested electrophysiologically and weighed. Results were compared between rats that had received versus not received nandrolone and versus 20 nongrafted controls. Results. Rats in the nandrolone group recovered finger flexion faster. At 90 days postsurgery, they had recovered 42% of normal grasp strength versus just 11% in rats grafted but not treated with nandrolone. At 180 days, the average values for grasp strength recovery in the nandrolone and no-nandrolone groups were 40% and 33% of normal values for controls, respectively. At 180 days, finger flexor muscle twitch strength was 16% higher in treated versus nontreated rats. Thresholds for nociception were not detected in either group 90 days after nerve grafting. At 180 days, nociceptive thresholds were significantly lower in the nandrolone group. Conclusions. Nandrolone decanoate improved functional recovery in a model of deficient reinnervation.

Abstract
OBJECTIVES To systematically review the evidence for using anabolic-androgenic steroids (AAS) to aid rehabilitation following total knee replacement (TKR). DESIGN Systematic review of all clinical study designs. DATA SOURCES MEDLINE, EMBASE, AMED, CINAHL and the Cochrane Library were searched from inception to August 2012. ELIGIBILITY CRITERIA All clinical study designs without language or patient demographic limits. OUTCOME MEASURES All functional, physiological and administrative outcomes as well as reporting of adverse events. RESULTS Only two small randomised controlled trials satisfied the inclusion criteria. Statistically significant improvements were reported in the AAS group for quadriceps strength at 3 (p=0.02), 6 (p=0.01) and 12 (p=0.02) months, Functional Independence Measure score at 35 days (p=<0.05) and Knee Society Score at 6 weeks (p=0.02), 6 months (p=0.04) and 12 months (p=0.03). However, differences in hamstring strength, bone mineral density, sit-to-stand testing, walking speed, length of hospital stay and need for further inpatient rehabilitation did not reach statistical significance. There were no reported adverse events. CONCLUSIONS There is insufficient evidence to recommend routine administration of AAS to patients undergoing TKR. However, pilot data suggest that AAS can be administered safely and may improve important postoperative outcome measures. This justifies a randomised trial sufficiently powered to identify between-group differences likely to be of clinical significance.
