[PMID: 35964860 DOI: 10.1016/j.eprac.2022.08.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Revised: 08/04/2022] [Accepted: 08/08/2022] [Indexed: 11/19/2022]
Abstract
OBJECTIVE To summarize all available data, using systematic review and meta-analysis, to estimate 1.) one-year mortality risk following AFF and 2.) risk ratio of mortality following AFF versus TFF. METHODS Potentially eligible studies were identified from Medline and EMBASE databases from inception to February 2022 using search strategy that comprised of terms for "Atypical Femoral Fracture" and "Mortality". Eligible study must consist of a cohort of patients with atypical femoral fracture. Then, the study must report one-year mortality rate following AFF or report effect estimates with 95% confidence intervals (95% CIs) comparing incident mortality between patients with AFF and TFF. Point estimates with standard errors were retrieved from each study and were combined using the generic inverse variance method. RESULTS A total of 8,967 articles were identified. After two rounds of independent review by three investigators, we identified seven studies reporting one-year mortality rate of AFF and three studies comparing mortality rate of AFF versus TFF. Pooled analysis revealed pooled one-year mortality rate following AFF of 0.10 (95% CI, 0.05 - 0.16, I2 93.3%). Two studies compared mortality risks of the AFF versus TFF and revealed conflicting results. CONCLUSION One-year mortality rate following AFF was approximately 10%. However, evidence is insufficient to conclude if there was difference in mortality risk between AFF and TFF.

Abstract
Fragility fracture is a worldwide problem and a main cause of disability and impaired quality of life. It is primarily caused by osteoporosis, characterized by impaired bone quantity and or quality. Proper diagnosis of osteoporosis is essential for prevention of fragility fractures. Osteoporosis can be primary in postmenopausal women because of estrogen deficiency. Secondary forms of osteoporosis are not uncommon in both men and women. Most systemic illnesses and organ dysfunction can lead to osteoporosis. The kidney plays a crucial role in maintaining physiological bone homeostasis by controlling minerals, electrolytes, acid-base, vitamin D and parathyroid function. Chronic kidney disease with its uremic milieu disturbs this balance, leading to renal osteodystrophy. Diabetes mellitus represents the most common secondary cause of osteoporosis. Thyroid and parathyroid disorders can dysregulate the osteoblast/osteoclast functions. Gastrointestinal disorders, malnutrition and malabsorption can result in mineral and vitamin D deficiencies and bone loss. Patients with chronic liver disease have a higher risk of fracture due to hepatic osteodystrophy. Proinflammatory cytokines in infectious, autoimmune, and hematological disorders can stimulate osteoclastogenesis, leading to osteoporosis. Moreover, drug-induced osteoporosis is not uncommon. In this review, we focus on causes, pathogenesis, and management of secondary osteoporosis.

Abstract
CONTEXT Atypical femur fractures (AFFs) are serious adverse events associated with bisphosphonates and often show poor healing. EVIDENCE ACQUISITION We performed a systematic review to evaluate effects of teriparatide, raloxifene, and denosumab on healing and occurrence of AFF. EVIDENCE SYNTHESIS We retrieved 910 references and reviewed 67 papers, including 31 case reports, 9 retrospective and 3 prospective studies on teriparatide. There were no RCTs. We pooled data on fracture union (n = 98 AFFs on teriparatide) and found that radiological healing occurred within 6 months of teriparatide in 13 of 30 (43%) conservatively managed incomplete AFFs, 9 of 10 (90%) incomplete AFFs with surgical intervention, and 44 of 58 (75%) complete AFFs. In 9 of 30 (30%) nonoperated incomplete AFFs, no union was achieved after 12 months and 4 (13%) fractures became complete on teriparatide. Eight patients had new AFFs during or after teriparatide. AFF on denosumab was reported in 22 patients, including 11 patients treated for bone metastases and 8 without bisphosphonate exposure. Denosumab after AFF was associated with recurrent incomplete AFFs in 1 patient and 2 patients of contralateral complete AFF. Eight patients had used raloxifene before AFF occurred, including 1 bisphosphonate-naïve patient. CONCLUSIONS There is no evidence-based indication in patients with AFF for teriparatide apart from reducing the risk of typical fragility fractures, although observational data suggest that teriparatide might result in faster healing of surgically treated AFFs. Awaiting further evidence, we formulate recommendations for treatment after an AFF based on expert opinion.

Abstract
Numerous safe and efficient drug therapies are currently available to decrease risk of low trauma fractures in patients with osteoporosis including postmenopausal, male, and secondary osteoporosis. In this chapter, we give first an overview of the most important outcomes regarding fracture risk reduction, change in bone mineral density (BMD by DXA) and/or bone markers of the phase III clinical studies of well-established therapies (such as Bisphosphonates, Denosumab or Teriparatide) and also novel therapies (such as Romosozumab or Abaloparatide) and highlight their mechanisms of action at bone tissue/material level. The latter understanding is not only essential for the choice of drug, duration and discontinuation of treatment but also for the interpretation of the clinical outcomes (in particular of eventual changes in BMD) after drug administration. In the second part of this chapter, we focus on the management of different forms of osteoporosis and give a review of the respective current guidelines for treatment. Adverse effects of treatment such as atypical femoral fractures, osteonecrosis of the jaw or influence of fracture healing are considered also in this context.

Abstract
BACKGROUND Atrial fibrillation (AF) and hip fractures are both prevalent in the elderly population. The aim of this study was to systematically review the literature regarding the association between AF and hip fractures, and the impact of AF on hip fracture prognosis. METHODS The literature search was performed using PubMed, MEDLINE, Embase and Scopus. Inclusion was based upon the application of eligibility criteria in duplicate prior to data extraction with a standardized form. RESULTS A total of 42 studies met the inclusion criteria. AF prevalence was found to vary between 6.5% and 35% in cohorts. Large studies with broad inclusion criteria found the prevalence of AF in hip fracture patients to be approximately 12-15%. There were conflicting results as to whether patients with AF have an increased rate of hip fractures, as compared to patients without AF. Several studies demonstrated that hip fracture patients with AF have increased rates of mortality, both as an inpatient and following discharge, and increased readmission rates. CONCLUSION AF and hip fractures frequently coexist, and there is evidence to suggest AF is associated with increased readmission and mortality rates in hip fracture patients. Elements of the relationship between AF and hip fractures remain uncertain and further prospective studies on AF and hip fracture cohorts may clarify this relationship. Interventional studies targeting hip fracture patients with AF may be beneficial.

Abstract
OBJECTIVES To determine the skeletal safety and efficacy of long term (≥10 years) alendronate use in patients with osteoporosis. DESIGN Open register based cohort study containing two nested case control studies. SETTING Nationwide study of population of Denmark. PARTICIPANTS 61 990 men and women aged 50-94 at the start of treatment, who had not previously taken alendronate, 1996-2007. INTERVENTIONS Treatment with alendronate. MAIN OUTCOME MEASURES Incident fracture of the subtrochanteric femur or femoral shaft (ST/FS) or the hip. Non-fracture controls from the cohort were matched to fracture cases by sex, year of birth, and year of initiation of alendronate treatment. Conditional logistic regression models were fitted to calculate odds ratios with and without adjustment for comorbidity and comedications. Sensitivity analyses investigated subsequent treatment with other drugs for osteoporosis. RESULTS 1428 participants sustained a ST/FS (incidence rate 3.4/1000 person years, 95% confidence interval 3.2 to 3.6), and 6784 sustained a hip fracture (16.2/1000 person years, 15.8 to 16.6). The risk of ST/FS was lower with high adherence to treatment with alendronate (medication possession ratio (MPR, a proxy for compliance) >80%) compared with poor adherence (MPR <50%; odds ratio 0.88, 0.77 to 0.99; P=0.05). Multivariable adjustment attenuated this association (adjusted odds ratio 0.88, 0.77 to 1.01; P=0.08). The risk was no higher in long term users (≥10 dose years; 0.70, 0.44 to 1.11; P=0.13) or in current compared with past users (0.91, 0.79 to 1.06; P=0.22). Similarly, MPR >80% was associated with a decreased risk of hip fracture (0.73, 0.68 to 0.78; P<0.001) as was longer term cumulative use for 5-10 dose years (0.74, 0.67 to 0.83; P<0.001) or ≥10 dose years (0.74, 0.56 to 0.97; P=0.03). CONCLUSIONS These findings support an acceptable balance between benefit and risk with treatment with alendronate in terms of fracture outcomes, even for over 10 years of continuous use.
