Objective: The development of these guidelines is sponsored by the American Association of Clinical Endocrinologists (AACE) Board of Directors and American College of Endocrinology (ACE) Board of Trustees and adheres with published AACE protocols for the standardized production of clinical practice guidelines (CPG). Methods: Recommendations are based on diligent reviews of the clinical evidence with transparent incorporation of subjective factors, according to established AACE/ACE guidelines for guidelines protocols. Results: The Executive Summary of this 2020 updated guideline contains 52 recommendations: 21 Grade A (40%), 24 Grade B (46%), 7 Grade C (14%), and no Grade D (0%). These detailed, evidence-based recommendations allow for nuance-based clinical decision-making that addresses multiple aspects of real-world care of patients. The evidence base presented in the subsequent Appendix provides relevant supporting information for the Executive Summary recommendations. This update contains 368 citations: 123 (33.5%) EL 1 (highest), 132 (36%) EL 2 (intermediate), 20 (5.5%) EL 3 (weak), and 93 (25%) EL 4 (lowest). New or updated topics in this CPG include: clarification of the diagnosis of osteoporosis, stratification of the patient according to high-risk and very high-risk features, a new dual action therapy option, and transitions from therapeutic options. Conclusion: This guideline is a practical tool for endocrinologists, physicians in general, regulatory bodies, health-related organizations, and interested laypersons regarding the diagnosis, evaluation, and treatment of postmenopausal osteoporosis.

AbstractSuboptimal nutrition has been implicated in the underlying pathology of behavioral health disorders and may impede treatment and recovery. Thus, optimizing nutritional status should be a treatment for these disorders and is likely important for prevention. The purpose of this narrative review is to describe the global burden and features of depression and anxiety, and summarize recent evidence regarding the role of diet and nutrition in the prevention and management of depression and anxiety. Current evidence suggests that healthy eating patterns that meet food-based dietary recommendations and nutrient requirements may assist in the prevention and treatment of depression and anxiety. Randomized controlled trials are needed to better understand how diet and nutrition-related biological mechanisms affect behavioral health disorders, to assist with the development of effective evidence-based nutrition interventions, to reduce the impact of these disorders, and promote well-being for affected individuals.

Objective The development of these updated clinical practice guidelines (CPGs) was commissioned by the American Association of Clinical Endocrinologists (AACE), The Obesity Society (TOS), American Society for Metabolic and Bariatric Surgery (ASMBS), Obesity Medicine Association (OMA), and American Society of Anesthesiologists (ASA) Boards of Directors in adherence with the AACE 2017 protocol for standardized production of CPGs, algorithms, and checklists. Methods Each recommendation was evaluated and updated based on new evidence from 2013 to the present and subjective factors provided by experts. Results New or updated topics in this CPG include: contextualization in an adiposity‐based chronic disease complications‐centric model, nuance‐based and algorithm/checklist‐assisted clinical decision‐making about procedure selection, novel bariatric procedures, enhanced recovery after bariatric surgery protocols, and logistical concerns (including cost factors) in the current health care arena. There are 85 numbered recommendations that have updated supporting evidence, of which 61 are revised and 12 are new. Noting that there can be multiple recommendation statements within a single numbered recommendation, there are 31 (13%) Grade A, 42 (17%) Grade B, 72 (29%) Grade C, and 101 (41%) Grade D recommendations. There are 858 citations, of which 81 (9.4%) are evidence level (EL) 1 (highest), 562 (65.5%) are EL 2, 72 (8.4%) are EL 3, and 143 (16.7%) are EL 4 (lowest). Conclusions Bariatric procedures remain a safe and effective intervention for higher‐risk patients with obesity. Clinical decision‐making should be evidence based within the context of a chronic disease. A team approach to perioperative care is mandatory, with special attention to nutritional and metabolic issues.

Abstract Context: Most association studies of bone-related biomarkers (BBMs) with bone mineral density (BMD) have been conducted in postmenopausal women. Objective: We tested whether the following BBMs were cross-sectionally associated with BMD among young adults: serum 1,25-dihydroxyvitamin D (1,25(OH)2D), 25-hydroxyvitamin D (25OHD), PTH, osteocalcin, bone-specific alkaline phosphatase (BAP), and urinary pyridinoline/urinary creatinine. Setting and Participants: We studied 319 individuals (134 women, 149 black, 24–36 years) recruited during 1992 through 1993 in Oakland, California. BMD was assessed with dual-energy x-ray absorptiometry. Linear regression models estimated the association between BMD and each BBM. Results: 1,25(OH)2D was inversely associated with all BMDs. 25OHD was positively, and PTH inversely, associated with lumbar spine, total hip, and whole-body BMD. BAP was inversely associated with left arm, right arm, and whole-body BMD but not with spine or hip BMD. Neither osteocalcin nor urinary pyridinoline/urinary creatinine was associated with BMD. When we placed all BBMs (including 1,25(OH)2D) in one model, the pattern and magnitude of association was similar except for PTH, which was attenuated. The association of BMD and BBMs did not differ significantly by race or sex. Conclusions: In this cross-sectional study of healthy young men and women who had PTH levels considered normal in clinical practice, higher PTH was associated with lower BMD, particularly in weight-bearing sites (ie, spine and hip). The inverse association of 1,25(OH)2D, together with the attenuation of PTH, suggests that the observed association of PTH is mediated by 1,25(OH)2D. BAP was inversely associated with arm BMD. BBMs can be important markers of skeletal activity in young adults, but their clinical role on bone health among this population is yet to be fully determined.

Abstract Estrogen (E) therapy and administration of oral contraceptives (OC) reportedly increase plasma calcitonin (CT) concentrations in women, effects said to mediate in part the beneficial actions of E on bone. To further examine this theory, we tested the effects of three cycles of OC therapy in 12 young women, comparing them to 10 healthy women before and after three normal menstrual cycles. We also determined the effects of 3 months of E therapy (ethinyl estradiol, 20 μg/day, 25 of 30 days) in 14 healthy postmenopausal women, using a crossover design (studied after 3 months with and 3 months without E). We determined CT by radioimmunoassay (antiserum G-1701) in whole plasma (iCT) and silica cartridge extracts of plasma (exCT) after overnight fasting, after calcium (Ca) infusion (2 mg Ca/kg over 5 minutes), and during a normal day at 0800, 1200, 1700, and 2000 h. In no control study was there a significant diurnal change in iCT or exCT, and neither OC nor E therapy altered this. Similarly, OC administration did not affect basal CT levels or the normal iCT and exCT responses to Ca infusion. E therapy induced expected changes in serum Ca, phosphorus, and alkaline phosphatase and urinary Ca and cAMP excretion; basal and diurnal plasma exCT levels were decreased significantly, consonant with the decrement in serum Ca. E did not alter normal iCT and exCT responses to Ca infusion. Thus, administration of either OC or E has no stimulatory effect on CT secretion, which suggests that the beneficial actions of E on bone are not mediated through CT-induced inhibition of bone resorption. Interaction of E with CT action at the cellular level is not excluded by these findings, but there are no data to support such a proposal.
