RESUMO
BACKGROUND: Most periprosthetic fractures following total hip arthroplasty (THA) are fragility fractures that qualify patients for osteoporosis diagnoses. However, it remains unknown how many patients were diagnosed who had osteoporosis before injury or received the proper evaluation, diagnosis, and treatment after injury. METHODS: We identified 171 Vancouver B2 (109) and B3 (62) periprosthetic femur fractures treated with a modular fluted tapered stem from 2000 to 2018 at 1 institution. The mean patient age was 75 years (range, 35 to 94), 50% were women, and the mean body mass index was 29 (range, 17 to 60). We identified patients who had osteoporosis or osteopenia diagnoses, a fracture risk assessment tool (FRAX), bone mineral density (BMD) testing, an endocrinology consult, and osteoporosis medications. Age-appropriate BMD testing was defined as no later than 1 year after the recommended ages of 65 (women) or 70 years (men). The mean follow-up was 11 years (range, 4 to 21). RESULTS: Falls from standing height caused 94% of fractures and thus, by definition, qualified as osteoporosis-defining events. The prevalence of osteoporosis diagnosis increased from 20% before periprosthetic fracture to 39% after (P < .001). The prevalence of osteopenia diagnosis increased from 13% before the fracture to 24% after (P < .001). The prevalence of either diagnosis increased from 24% before fracture to 44% after (P < .001). No patients had documented FRAX scores before fracture, and only 2% had scores after. The prevalence of BMD testing was 21% before fracture and 22% after (P = .88). By the end of the final follow-up, only 16% had received age-appropriate BMD testing. The proportion of patients who had endocrinology consults increased from 6% before the fracture to 25% after (P < .001). The proportion on bisphosphonate therapy was 19% before fracture and 25% after (P = .08). CONCLUSIONS: Although most periprosthetic fractures following THA are fragility fractures that qualify patients for osteoporosis diagnoses, there remain major gaps in diagnosis, screening, endocrinology follow-up, and treatment. Like nonarthroplasty fragility fractures, a systematic approach is needed after periprosthetic fractures. LEVEL OF EVIDENCE: Level III, retrospective cohort study.
RESUMO
Osteoporotic fractures among long-term care residents have substantial economic and human costs. After a fracture, many older adults do not receive an osteoporosis diagnosis or evidence-based treatment, which leads to increased risk of recurrent fractures. Optimal processes are well defined for transitioning medical care after a hip or vertebral fracture for osteoporosis evaluation, but the handoff process from the specialist back to a primary care practitioner (PCP) or to a rehabilitative setting is not well defined. Our interdisciplinary quality improvement team developed and evaluated a program for transitioning care from a hospital-based fracture liaison clinic (FLC) to PCPs caring for older adults across the care continuum. To understand the current process of postfracture care transitions, we analyzed the postfracture patient experience. We surveyed PCPs to assess barriers to osteoporosis treatment, and retrospectively conducted a baseline analysis of 87 patients who had sustained an osteoporotic fracture in 2020. This preliminary work showed several opportunities for practice improvement and helped us develop a practical multicomponent intervention aimed at improving care transitions from the FLC to PCPs. The intervention (June-September 2021) comprised a standardized documentation template in the electronic health record (EHR) for FLC clinicians, a structured handoff process, and an engagement tool for patients outlining the roles and responsibilities of each care team member. We compared care transition measures before and after intervention. EHR documentation of an osteoporosis diagnosis increased from 56% (49 of 87 patients) before intervention to 92% (48 of 52) after intervention (P < .001). Additionally, increases were observed in documentation of treatment recommendations, associated risk factors, and PCP discussions with patients regarding osteoporosis and related treatment. This practical, commonsense intervention established clear roles for each care team member. The intervention addressed systemwide barriers in facilitating a safe transition from a subspecialty care team to PCPs providing care to older adults with osteoporosis.

OBJECTIVE: Osteoporosis is a common condition that can be caused or exacerbated by estrogen deficiency. METHODS: This narrative review will discuss optimizing bone health in the setting of adjuvant endocrine treatments for hormone receptor-positive breast cancer and the current use of antiresorptive agents as adjuvant therapy and as bone modifying agents. RESULTS: Adjuvant endocrine treatments for hormone receptor-positive breast cancer (tamoxifen and aromatase inhibitors) affect bone health. The exact effect depends on the agent used and the menopausal state of the woman. Antiresorptive medications for osteoporosis, bisphosphonates and denosumab, lower the risk of bone loss from aromatase inhibitors. Use of bisphosphonates as adjuvant treatment in breast cancer, regardless of hormone receptor status, is increasing because of benefits seen to cancer relapse and survival. CONCLUSION: Optimizing bone health in women with breast cancer during and after cancer treatment is informed by an understanding of breast cancer treatment and its skeletal effect.

INTRODUCTION: Both osteoporosis and cardiovascular disease (CVD) increase in women after menopause. Estrogen deficiency is thought to be an underlying mechanism for both these conditions. METHODS: Healthy menopausal women (n = 374, age 42-58 years) underwent cardiac CT scans over four years as participants in the Kronos Early Estrogen Prevention Study (KEEPS), a randomized, controlled trial to Women randomized to either oral conjugated equine estrogens (o-CEE, n = 104), transdermal 17ß-estradiol (t-E2, n = 119) or placebo (n-115). CAC (Agatston units, AU), and BMD (mg/cm3) were measured from thoracic vertebrae at baseline and at the 4 years of the study using validated software. ANOVA and multiple linear regression analyzed the association between incident CAC or progression of CAC and BMD among the treatment groups. RESULTS: At baseline 374 women, 40 participants with CAC >0 had greater decrements in BMD than the 334 participants with CAC = 0 at baseline, The average change in BMD in o-CEE group with CAC was -9.6 ± 13.3 versus -3.1 ± 19.5 in those with zero CAC, p = 0.0018. With t-E2, BMD changed by -11.7 ± 26.2 in those with CAC versus +5.7 ± 26.2 in the zero CAC group, p ≤ 0. 0001. Similarly in the 66 participants that showed progression of CAC >1, had more BMD loss, than those with stable CAC regardless of the treatment. CONCLUSION: Progression of bone loss is reduced among women treated with o-CEE or t-E2. Progression of CAC is associated with greater BMD loss, a relationship that is differentially modified by t-E2 and o-CEE.

CONTEXT: Survival in patients with primary hyperparathyroidism (PHPT) remains uncertain. OBJECTIVE: To update survival in patients with PHPT in a United States community population. DESIGN: Retrospective cohort study. SETTING: Community population in Rochester, Minnesota. PARTICIPANTS: Residents who met criteria for PHPT from 1965 to 2010. INTERVENTIONS: Survival was estimated using the Kaplan Meier product-limit method. The Cox proportional hazards model was used to determine associations, as relative hazards (RR) with 95% confidence intervals (CI), of various risk factors with time to death. MAIN OUTCOME MEASURE: The overall age and gender-adjusted survival compared to white Minnesota residents. RESULTS: We identified 1139 PHPT individuals, 76% female, with a median age of 58 years. Most were observed without parathyroidectomy (69%). The relative risk of death among the entire cohort was 0.996 (95% CI: 0.91-1.09, P = 0.935) which was not different compared to Minnesota residents. Those with maximum serum calcium level ≥ 10.8 mg/dL (0.7 mg/dL above the reference range) had an increase in mortality (RR 1.32, 95% CI: 1.10-1.58, P = 0.002). Survival among all PHPT individuals after parathyroidectomy was no different from expected (RR = 1.06, 95% CI 0.89-1.28; P = 0.508). Mortality was significantly decreased after parathyroidectomy in those with serum calcium levels ≥10.8 mg/dL (HR 0.47, 95% CI: 0.36-0.61, P < 0.001). CONCLUSIONS: Mortality in the entire cohort was not different from expected. PHPT patients with a maximum serum calcium level ≥ 10.8 mg/dL had increased mortality. Survival was improved after parathyroidectomy in those with this degree of hypercalcemia.

OBJECTIVE: Orthotopic liver transplant recipients are at high risk of fragility fractures both in pre-liver transplant (pre-LT) and in the immediate posttransplant (post-LT) period. The aims of this study were to identify risk factors associated with post-LT fracture and identify factors that contribute to changes in bone mineral density (BMD) in post-LT as they relate to the risk of fracture in the immediate post-LT period. METHODS: We conducted a retrospective cohort study of first-time LT recipients who had BMD testing within 2-year pre-LT and 1-year post-LT. We assessed factors associated with immediate post-LT fracture using logistic regression models and linear regression models. RESULTS: New fractures occurred in 41/286 (14.3%) of LT recipients during the first year following LT. In multivariate analysis, we noted an increased odds of fracture for patients with prior history of fracture (P < .001), patients who were older (P = .03), patients with higher end-stage liver disease score (P = .03), and patients with lower BMD. After adjustment for multiple testing, only a history of prior fracture was statistically significant. CONCLUSION: Our study demonstrated that prior fracture at any site was associated with developing a new fracture in the first year post-LT.

Osteoporosis-related fractures are undertreated, due in part to misinformation about recommended approaches to patient care and discrepancies among treatment guidelines. To help bridge this gap and improve patient outcomes, the American Society for Bone and Mineral Research assembled a multistakeholder coalition to develop clinical recommendations for the optimal prevention of secondary fractureamong people aged 65 years and older with a hip or vertebral fracture. The coalition developed 13 recommendations (7 primary and 6 secondary) strongly supported by the empirical literature. The coalition recommends increased communication with patients regarding fracture risk, mortality and morbidity outcomes, and fracture risk reduction. Risk assessment (including fall history) should occur at regular intervals with referral to physical and/or occupational therapy as appropriate. Oral, intravenous, andsubcutaneous pharmacotherapies are efficaciousandcanreduce risk of future fracture.Patientsneededucation,however, about thebenefitsandrisks of both treatment and not receiving treatment.

BACKGROUND: Cardiac fat is emerging as an important parameter for cardiovascular risk stratification. Accurate and reproducible volumetric measurements can facilitate in the serial assessment of cardiac fat by computed tomography (CT). We assessed the intra- and inter-observer variability of cardiac fat volumetric measurements using a semi-automated CT software. METHODS: We used non-contrast coronary calcium CT scans to quantify epicardial and intra-thoracic fat volumes. Two expert readers analyzed baseline and follow up CT scans of 45 subjects by using a semi-automated CT software (QFAT 2.0, Cedars Sinai-Medical Center). Correlation and Bland-Altman analysis was performed for both intra- and inter-observer comparisons for each cardiac fat type. RESULTS: The intra-observer correlation coefficients ranged between 0.86 to 0.99 and 0.87 to 0.99 for epicardial (median fat per reader (cm3) 20.9 to 25.7) and intra-thoracic (median fat per reader (cm3) 27.1 to 31.6) fat volumes respectively, with no significant differences between individual data points (all pâ¯>â¯0.38). The inter-observer correlation coefficient was 0.99 (pâ¯<â¯0.0001 for correlation) for both epicardial and intra-thoracic fat. By Bland-Altman analysis for epicardial fat measurements, mean difference of intra-observer was 0.90â¯cm3 with 95% confidence intervals (0.22,1.7) and -1.8â¯cm3 for inter-observer, with 95% CI (-2.9, -0.69). Bland-Altman plots for intra-thoracic fat measurements were similarly impressive for both inter- and intra-observer reads. CONCLUSIONS: Our data showed that measuring epicardial and intra-thoracic fat volumes by CT using a semi-automated software has excellent intra-observer and inter-observer reliability. Cardiac fat volumes can be obtained easily and reproducibly from routine calcium scoring scans and may help in assessing cardiovascular risk.

Background Heart fats (epicardial and paracardial adipose tissue [PAT]) are greater after menopause. Endogenous estrogen may regulate these fat depots. We evaluated the differential effects of hormone therapy formulations on heart fat accumulations and their associations with coronary artery calcification (CAC) progression in recently menopausal women from KEEPS (Kronos Early Estrogen Prevention Study). Methods and Results KEEPS was a multicenter, randomized, placebo-controlled trial of the effects of 0.45 mg/d oral conjugated equine estrogens and 50 µg/d transdermal 17ß-estradiol, compared with placebo, on 48-month progression of subclinical atherosclerosis among 727 early menopausal women. CAC progression was defined if baseline CAC score was 0 and 48-month CAC score was >0 or if baseline CAC score was >0 and <100 and annualized change in CAC score was ≥10. Of 727 KEEPS participants, 474 (mean age: 52.7 [SD: 2.6]; 78.1% white) had computed tomography-based heart fat and CAC measures at both baseline and 48 months. Compared with women on placebo, women on oral conjugated equine estrogens were less likely to have any increase in epicardial adipose tissue (odds ratio for oral conjugated equine estrogens versus placebo: 0.62 [95% CI, 0.40-0.97]; P=0.03). PAT did not change in any group. Changes in epicardial adipose tissue and PAT did not differ by treatment group. CAC increased in 14% of participants. The assigned treatment modified the association between PAT changes and CAC progression (P=0.02) such that PAT increases were associated with CAC increases only in the transdermal 17ß-estradiol group. Conclusions In recently menopausal women, oral conjugated equine estrogens may slow epicardial adipose tissue accumulation, whereas transdermal 17ß-estradiol may increase progression of CAC associated with PAT accumulation.

OBJECTIVE: Several studies indicate that patients with primary hyperparathyroidism (PHPT) undergoing parathyroid surgery have improvement in mood and neuropsychological functioning. The current analysis aims to examine the relationship between biochemical and clinical variables and the improvement in depression scores and in specific symptoms, after parathyroidectomy. DESIGN: A prospective observational case-control study at a referral centre. PATIENTS: Patients with PHPT undergoing parathyroidectomy (n = 88) or thyroid surgery (n = 85). MEASUREMENTS: The Patient Health Questionnaire-9 (PHQ-9) was utilized to obtain depression scores at enrolment and 12 months after surgery. The changes in PHQ-9 were analysed and correlated with baseline clinical and biochemical parameters. RESULTS: At enrolment, there was no difference between the groups in the number with a depression diagnosis (PHPT 34.1%, thyroid surgery, 35.5%, P = 0.86). However, baseline PHQ-9 scores were significantly higher in PHPT (median 7.5, range 0-27) than thyroid surgery patients (median 3.0, range 0-18, P < 0.0001). Following surgery, all PHQ-9 scores, total and symptom group (cognitive, somatic) improved and were no longer different between PHPT (total PHQ-9 median 2, range 0-16) and thyroid (median 1, range 0-14, P = 0.31) groups. Baseline parathyroid hormone level, but not calcium, had a weak relationship with change in PHQ-9 score after parathyroid surgery (P = 0.003). Baseline PHQ-9 score was correlated with change in PHQ-9 score at 12 months after parathyroid surgery (P < 0.001). CONCLUSIONS: Depression scores improve in both somatic and cognitive domains after parathyroidectomy for PHPT and baseline severity of depression predicts the response.

CONTEXT: Thiazide diuretics, the antihypertensive agent prescribed most frequently worldwide, are commonly associated with hypercalcemia. However, the epidemiology and clinical features are poorly understood. OBJECTIVE: To update the incidence of thiazide-associated hypercalcemia and clarify its clinical features. PATIENTS AND METHODS: In a population-based descriptive study, Olmsted County, Minnesota, residents with thiazide-associated hypercalcemia were identified through the Rochester Epidemiology Project and the Mayo Clinic Laboratory Information System from 2002-2010 and were added to the historical cohort beginning in 1992. MAIN OUTCOME: Incidence rates were adjusted to the 2010 United States white population. RESULTS: Overall, 221 Olmsted County residents were identified with thiazide-associated hypercalcemia an average of 5.2 years after initiation of treatment. Subjects were older (mean age, 67 years) and primarily women (86.4%). The incidence of thiazide-associated hypercalcemia increased after 1997 and peaked in 2006 with an annual incidence of 20 per 100,000, compared to an overall rate of 12 per 100,000 in 1992-2010. Severe hypercalcemia was not observed in the cohort despite continuation of thiazide treatment in 62.4%. Of patients discontinuing thiazides, 71% continued to have hypercalcemia. Primary hyperparathyroidism was diagnosed in 53 patients (24%), including five patients who underwent parathyroidectomy without thiazide discontinuation. CONCLUSIONS: Many patients with thiazide-associated hypercalcemia have underlying primary hyperparathyroidism. Additionally, a sharp rise in thiazide-associated hypercalcemia incidence began in 1998, paralleling the increase observed in primary hyperparathyroidism in this community. Case ascertainment bias from targeted osteoporosis screening is the most likely explanation.

OBJECTIVE: To determine which residency characteristics are associated with performance during endocrinology fellowship training as measured by competency-based faculty evaluation scores and faculty global ratings of trainee performance. METHODS: We performed a retrospective review of interview applications from endocrinology fellows who graduated from a single academic institution between 2006 and 2013. Performance measures included competency-based faculty evaluation scores and faculty global ratings. The association between applicant characteristics and measures of performance during fellowship was examined by linear regression. RESULTS: The presence of a laudatory comparative statement in the residency program director's letter of recommendation (LoR) or experience as a chief resident was significantly associated with competency-based faculty evaluation scores (ß = 0.22, P = .001; and ß = 0.24, P = .009, respectively) and faculty global ratings (ß = 0.85, P = .006; and ß = 0.96, P = .015, respectively). CONCLUSION: The presence of a laudatory comparative statement in the residency program director's LoR or experience as a chief resident were significantly associated with overall performance during subspecialty fellowship training. Future studies are needed in other cohorts to determine the broader implications of these findings in the application and selection process.

BACKGROUND: Postmenopausal women with breast cancer receiving aromatase inhibitors are at an increased risk of bone loss. The current study was undertaken to determine whether upfront versus delayed treatment with zoledronic acid (ZA) impacted bone loss. This report described the 5-year follow-up results. METHODS: A total of 551 postmenopausal women with breast cancer who completed tamoxifen treatment and were undergoing daily letrozole treatment were randomized to either upfront (274 patients) or delayed (277 patients) ZA at a dose of 4 mg intravenously every 6 months. In the patients on the delayed treatment arm, ZA was initiated for a postbaseline bone mineral density T-score of <-2.0 or fracture. RESULTS: The incidence of a 5% decrease in the total lumbar spine bone mineral density at 5 years was 10.2% in the upfront treatment arm versus 41.2% in the delayed treatment arm (P<.0001). A total of 41 patients in the delayed treatment arm were eventually started on ZA. With the exception of increased NCI Common Toxicity Criteria (CTC) grade 1/2 elevated creatinine and fever in the patients treated on the upfront arm and cerebrovascular ischemia among those in the delayed treatment arm, there were no significant differences observed between arms with respect to the most common adverse events of arthralgia and back pain. Osteoporosis occurred less frequently in the upfront treatment arm (2 vs 8 cumulative cases), although this difference was not found to be statistically significant. Bone fractures occurred in 24 patients in the upfront treatment arm versus 25 patients in the delayed treatment arm. CONCLUSIONS: Immediate treatment with ZA prevented bone loss compared with delayed treatment in postmenopausal women receiving letrozole and these differences were maintained at 5 years. The incidence of osteoporosis or fractures was not found to be significantly different between treatment arms.

Introduction of automated serum calcium measurements in the 1970s resulted in a sharp rise in primary hyperparathyroidism (PHPT) incidence. However, recent investigations suggest a significant rise in PHPT incidence for unclear reasons. Our objective was to update our population-based secular trends in PHPT incidence, to determine if there has been a significant rise in PHPT incidence as suggested by others, and, if possible, to identify changes in clinical practice that might be responsible. Rochester, Minnesota, residents who met the criteria for PHPT from 2002 through 2010 were identified through the medical records-linkage system of the Rochester Epidemiology Project and added to the historical cohort beginning in 1965. Incidence rates were adjusted to the 2010 US white population. Altogether, 1142 Rochester residents have been diagnosed with PHPT since 1965, including 341 in 2002-2010. Over time, two periods of increased PHPT incidence occurred, one beginning in 1974 (121.7 per 100,000 person-years) and a second peak (86.2 per 100,000 person-years) starting in 1998. The median age of PHPT subjects has increased significantly from 55 years in 1985-1997 to 60 years of age in 1998-2010 and more patients (36%) had a parathyroidectomy in 1998-2010. Although serum calcium measurement has declined since 1996, there was a progressive increase in parathyroid hormone testing between 1994 and 2008. There was also a rise in orders for bone mineral density measurements in women since 1998, which peaked in 2003-2004. A second sharp rise in PHPT incidence occurred in our community in 1998, simultaneously with the introduction of national osteoporosis screening guidelines, Medicare coverage for bone density measurement, and new medications for the treatment of osteoporosis. Case ascertainment bias from targeted PHPT screening in patients being evaluated for osteoporosis is the most likely explanation.

PURPOSE: To assess the quality of an initiative to improve the diagnosis and management of osteoporosis in patients over 50 years of age with distal radius fractures (DRF). METHODS: A retrospective review was conducted to determine the baseline percentage of individuals undergoing osteoporosis screening after DRF. Thereafter, a study was implemented in which DRF patients who were not being treated for osteoporosis or had not recently undergone screening were offered a dual-energy x-ray absorptiometry scan and referral to endocrinology at the initial hand surgery clinic visit. Patients who declined participation were contacted by a patient educator to discuss the benefits of screening and address their concerns. Those who then wanted to receive an osteoporosis evaluation were scheduled for bone scanning and endocrinology consultation. RESULTS: During the baseline period, 7 patients (15%) were screened, and 41 (85%) were not screened. During the active phase of the initiative, 82 patients over 50 years of age were treated for a DRF at our institution. A total of 44 patients were identified for potential osteoporosis screening, and 35 patients met inclusion criteria. Of these, 19 (54%) agreed to screening after the initial orthopedic evaluation, and 16 declined. After speaking to a patient educator, 9 of these 16 patients agreed to screening. Of the remaining 7 patients, 4 again declined screening and 3 were unavailable by telephone. Overall, 80% of patients who were identified in the initiative agreed to osteoporosis screening after the combination of recommendation during hand surgery clinic visit and patient education by telephone, and 64% were diagnosed with osteoporosis/osteopenia as a result of completing screening. CONCLUSIONS: An integrated model of care among orthopedic surgeons, patient educators, and endocrinologists substantially increased screening for osteoporosis after DRF. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.
