Loss of life years after a hip fracture

Bone parameters in T1D and T2D assessed by DXA and HR-pQCT - A cross-sectional study: The DIAFALL study

INTRODUCTION/AIM

People with type 1 diabetes(T1D) and type 2 diabetes(T2D) have an increased risk of fractures due to skeletal fragility. We aimed to compare areal bone mineral density(aBMD), volumetric BMD(vBMD), cortical and trabecular measures, and bone strength parameters in participants with diabetes vs. controls.

METHODS

In a cross-sectional study, we included participants with T1D(n = 111), T2D(n = 106) and controls(n = 328). The study comprised of whole-body DXA and HR-pQCT scans, biochemistry, handgrip strength(HGS), Timed Up and GO(TUG), vibration perception threshold (VPT), questionnaires, medical histories, alcohol use, and previous fractures. Group comparisons were performed after adjustment for sex, age, BMI, diabetes duration, HbA1c, alcohol, smoking, previous fractures, postmenopausal, HGS, TUG, and VPT.

RESULTS

We found decreased aBMD in participants with T1D at the femoral neck(p = 0.028), whereas T2D had significantly higher aBMD at peripheral sites(legs, arms, p < 0.01) vs. controls. In T1D we found higher vBMD(p < 0.001), cortical vBMD (p < 0.001), cortical area(p = 0.002) and thickness(p < 0.001), lower cortical porosity(p = 0.008), higher stiffness(p = 0.002) and failure load(p = 0.003) at radius and higher vBMD(p = 0.003), cortical vBMD(p < 0.001), bone stiffness(p = 0.023) and failure load(p = 0.044) at the tibia than controls. In T2D we found higher vBMD(p < 0.001), cortical vBMD(p < 0.001), trabecular vBMD(p < 0.001), cortical area (p < 0.001) and thickness (p < 0.001), trabecular number (p = 0.024), lower separation(p = 0.010), higher stiffness (p < 0.001) and failure load (p < 0.001) at the radius and higher total vBMD(p < 0.001), cortical vBMD(p < 0.011), trabecular vBMD(p = 0.001), cortical area(p = 0.002) and thickness(p = 0.021), lower trabecular separation(p = 0.039), higher stiffness(p < 0.001) and failure load(p = 0.034) at tibia compared with controls.

CONCLUSION

aBMD measures were as expected but favorable bone microarchitecture and strength parameters were seen at the tibia and radius for T1D and T2D.

Hormone Replacement Therapy After Breast Cancer: It Is Time

ABSTRACT

This article reviews the decades of evidence supporting the reproducible benefits of HRT for menopausal symptom control, improved cardiac health, prevention of hip fracture, reduction in the risk and pace of cognitive decline, and enhanced longevity. It quantifies the increased risk of thromboembolism associated with oral, though not transdermal, HRT. It evaluates the repeated claims that HRT is associated with an increased risk of breast cancer development, and, when administered to breast cancer survivors, an increased risk of breast cancer recurrence. Twenty-five studies of HRT after a breast cancer diagnosis, published between 1980 and 2013, are discussed, as are the 20 reviews of those studies published between 1994 and 2021. Only 1 of the 25 studies, the HABITS trial, demonstrated an increased risk of recurrence, which was limited to local or contralateral, and not distant, recurrence. None of the studies, including HABITS, reported increased breast cancer mortality associated with HRT. Even in the HABITS trial, the absolute increase in the number of women who had a recurrence (localized only) associated with HRT administration was 22. It is on the basis of these 22 patients that HRT, with its demonstrated benefits for so many aspects of women's health, is being denied to millions of breast cancer survivors around the world.

Determinants of Higher Mortality at Six Months in Patients with Hip Fracture: A Retrospective Study

(1) Background: Hip fracture is a pathology with high mortality, but the lack of a universal adaptation of the factors associated with death makes it difficult to predict risk and implement prevention in this group. This study aimed to identify the factors that determine a higher mortality at six months following hip fracture. (2) Methods: A retrospective longitudinal study, whose study population consisted of patients over 65 years of age. The main variable was mortality at 6 months of fracture. Relevant data related to sociodemographic and clinical variables for subsequent bivariate (χ²) and multivariate analysis were obtained. (3) Results: In all, 665 people participated in the study, 128 of whom died within 6 months of the fracture. The multivariate adjusted analysis demonstrated significant relationships between the main variable and aspects such as institutionalization at discharge (Odds Ratio (OR) = 2.501), a worse overall functional capacity (OR = 2.453) and cognitive capacity (OR = 3.040) at admission, and complications such as heart failure (OR = 5.767) or respiratory infection (OR = 5.308), in addition to the taking of certain drugs and the presence of a greater number of comorbidities. (4) Conclusions: There are certain factors related to higher mortality at six months in patients with hip fracture who are aged 65 years or older.

Influence of comorbidity on postoperative course and mortality in patients with hip fracture

Introduction/Objective. Epidemiological research shows that we have a dramatic increase in the number of people with hip fractures, especially those over 65 years of age. The main objectives of this study are to assess the association between preoperative comorbidity and the risk of postoperative complications and mortality and postoperative worsening of comorbid conditions and their relationship to mortality within one year of hip fracture surgery. Methods. In the period from January 2018. until January 2020. in a retrospective study, at the Department of Orthopedic Surgery in Kosovska Mitrovica, we operated 64 patients with hip fractures. We monitored the number of comorbidities and their significance on the preoperative risk and the course of concomitant diseases in the postoperative period and one - year mortality from surgery, in patients with hip fractures. Results. We collected data on patients from the moment of admission to discharge from the hospital accompanied by medical histories, and after discharge after follow-up examinations, six months and one year from discharge. Of the total number of subjects, 23 (35.9%) had one or two comorbidities, most often of cardiac and neurological nature, in 25 patients (39.1%) we had three concomitant diseases, and in 11 (17.2%) four and more comorbidities. The mean age of the patients was 72.51 years (69-92 years). Conclusion. Approximately 45-60% of men and women who suffer a hip fracture have three or more comorbid states. In older people with hip fractures, the presence of three or more comorbidities is the strongest preoperative risk factor.

Atrial fibrillation as a preoperative risk factor predicts long-term mortality in elderly patients without heart failure and undergoing hip fracture surgery

OBJECTIVE

Patients with atrial fibrillation (AF) constitute a significant portion of hip fracture patients, and both diseases tend to present more frequently in older age. Our goal was to evaluate the long-term mortality of patients with AF who were free from heart failure undergoing hip fracture surgery.

METHODS

This observational, retrospective study was done in a single research and training hospital setting. Hospital electronic health record data, National Health Registry data, and National Death Registry System data for 233 consecutive patients who were above 65 years of age and were planned to undergo surgery for hip fracture were retrieved and analyzed. An experienced cardiologist evaluated the patients prior to surgery. Each member of the research cohort was categorized into one of the two groups based on their survival status (survivor and non-survivor groups).

RESULTS

Of the 233 cases, 89 (38.2%) who were included in the investigation died during the follow-up period. The median long-term follow-up period was 34 (12-42) months. The frequency of AF was significantly higher in the non-survivor group. In multivariable Cox regression analysis, AF (HR: 2.195, 95%CI 1.365-3.415, p<0.001), advanced age, and blood urea level were determined as independent predictors for all-cause long-term mortality.

CONCLUSIONS

AF is an independent predictor for long-term death in hip fracture cases above 65 years of age who were free from heart failure.

Cost-effectiveness of group-based exercise to prevent falls in elderly community-dwelling people

BACKGROUND

Clinical studies indicate that strength-balance training for active fall prevention can prevent fractures in older people. The present modelling study evaluates the cost-effectiveness of fall prevention exercise (FPE) provided to independently living older people compared to no intervention in Germany.

METHOD

We designed a Markov model to evaluate the cost-effectiveness of a group-based FPE-program provided to independently living people ≥75 years from the perspective of the German statutory health insurance (SHI). Input data was obtained from public databases, clinical trials and official statistics. The incremental cost-effectiveness ratio (ICER) was presented as costs per avoided hip fracture. Additionally, we performed deterministic and probabilistic sensitivity analyses and, estimated monetary consequences for the SHI in a budget impact analysis (BIA).

RESULTS

For women, the costs per hip fracture avoided amounted to €52,864 (men: €169,805). Results of deterministic and probabilistic sensitivity analyses confirmed the robustness of the results. According to the BIA, for the reimbursement of FPE additional costs of €3.0 million (women) and €7.8 million (men) are expected for the SHI.

CONCLUSIONS

Group-based FPE appears to be no cost-effective option to prevent fall-related hip fractures in independently living elderly. To allow a more comprehensive statement on the cost effectiveness of FPE fracture types other than hip should be increasingly evaluated in clinical trials.

Risk factors and mortality of patients undergoing hip fracture surgery: a one-year follow-up study

Hip fracture (HF) remains a main issue in the elderly patient. About 1.6 million patients a year worldwide are victims of a HF. Their incidence is expected to rise with the aging of the world’s population. Identifying risk factors is mandatory in order to reduce mortality and morbidity. The aim of the study was to identify risk factors of 1-year mortality after HF surgery. We performed an observational, prospective, single-center study at Amiens University Hospital (Amiens, France). After ethical approval, we consecutively included all patients with a HF who underwent surgery between June 2016 and June 2017. Perioperative data were collected from medical charts and by interviews. Mortality rate at 12 months was recorded. Univariate analysis was performed and mortality risk factors were investigated using a Cox model. 309 patients were analyzed during this follow-up. Mortality at 1 year was 23.9%. Time to surgery over 48 hours involved 181 patients (58.6%) while 128 patients (41.4%) had surgery within the 48 hours following the hospital admission. Independent factors associated with 1-year mortality were: age (HR at 1.059 (95%CI [1.005–1.116], p = 0,032), Lee score ≥ 3 (HR at 1,52 (95% CI [1,052–2,198], p = 0.026) and time to surgery over 48 hours (HR of 1.057 (95% CI [1.007–1.108], p = 0.024). Age, delayed surgical (over 48 hours) management and medical history are important risk factors of 1-year mortality in this French cohort

Falls and Fractures in Diabetes-More than Bone Fragility

PURPOSE OF REVIEW

Based on a systematic literature search, we performed a comprehensive review of risk factors for falls and fractures in patients with diabetes.

RECENT FINDINGS

Patients with diabetes have an increased risk of fractures partly explained by increased bone fragility. Several risk factors as altered body composition including sarcopenia and obesity, impaired postural control, gait deficits, neuropathy, cardiovascular disease, and other co-morbidities are considered to increase the risk of falling. Diabetes and bone fragility is well studied, but new thresholds for fracture assessment should be considered. In general, the risk factors for falls in patients with diabetes are well documented in several studies. However, the fall mechanisms among diabetic patients have only been assessed in few studies. Thus, a gab of knowledge exits and may influence the current understanding and treatment, in order to reduce the risk of falling and thereby prevent fractures.

Impact of preadmission anti-inflammatory drug use on the risk of RBC transfusion in elderly hip fracture patients: a Danish nationwide cohort study, 2005-2016

BACKGROUND

Do prescription drugs with anti-inflammatory properties such as nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, and statins increase the risk of postoperative bleeding measured with RBC transfusion in elderly hip fracture surgery patients?

STUDY DESIGN AND METHODS

Using the Danish Multidisciplinary Hip Fracture Database, 74,791 patients aged 65 years or older with surgery-treated hip fracture were identified during 2005-2016, and their use of NSAIDs, corticosteroids, and statins was ascertained. For each drug, patients were categorized as nonusers (no prescription ≤365 days prior to surgery), former users (one prescription 91-365 days), and current users (one prescription ≤90 days). Information on surgical treatment, transfusion, other medication and comorbidities were collected using Danish nationwide registries. A log-binomial model was used to estimate relative risks for RBC transfusion within 7 days of surgery and corresponding 95% confidence intervals. Adjustments were made for patient- and surgery-related factors.

RESULTS

Former and current users of NSAIDs, corticosteroids, and statins accounted for 22%, 10%, and 24%, respectively. Current users of NSAIDs had an increased adjusted relative risk of transfusion (1.07; confidence interval, 1.04-1.10) compared to nonusers. There was no association between current users of corticosteroids and statins and risk of transfusion.

CONCLUSION

NSAID use within 90 days of a hip fracture surgery was associated with an increased risk of RBC transfusion. Thus, current use of NSAIDs can be associated with an increased risk of postoperative bleeding, but we cannot rule out the influence of confounding.

Mortality by Timing of Hip Fracture Surgery: Factors and Relationships at Play

In hip fracture care, it is disputed whether mortality worsens when surgery is delayed. This knowledge gap matters when hospital managers seek to justify resource allocation for prioritizing access to one procedure over another. Uncertainty over the surgical timing-death association leads to either surgical prioritization without benefit or the underuse of expedited surgery when it could save lives. The discrepancy in previous findings results in part from differences between patients who happened to undergo surgery at different times. Such differences may produce the statistical association between surgical timing and death in the absence of a causal relationship. Previous observational studies attempted to adjust for structure, process, and patient factors that contribute to death, but not for relationships between structure and process factors, or between patient and process factors. In this article, we (1) summarize what is known about the factors that influence, directly or indirectly, both the timing of surgery and the occurrence of death; (2) construct a dependency graph of relationships among these factors based explicitly on the existing literature; (3) consider factors with a potential to induce covariation of time to surgery and the occurrence of death, directly or through the network of relationships, thereby explaining a putative surgical timing-death association; and (4) show how age, sex, dependent living, fracture type, hospital type, surgery type, and calendar period can influence both time to surgery and occurrence of death through chains of dependencies. We conclude by discussing how these results can inform the allocation of surgical capacity to prevent the avoidable adverse consequences of delaying hip fracture surgery.

Mortality and readmission following hip fracture surgery: a retrospective study comparing conventional and fast-track care

OBJECTIVE

To compare the efficacies of two pathways-conventional and fast-track care-in patients with hip fracture.

DESIGN

Retrospective single-centre study.

SETTING

University hospital in middle Norway.

PARTICIPANTS

1820 patients aged ≥65 years with hip fracture (intracapsular, intertrochanteric or subtrochanteric).

INTERVENTIONS

788 patients were treated according to conventional care from April 2008 to September 2011, and 1032 patients were treated according to fast-track care from October 2011 to December 2013.

PRIMARY AND SECONDARY OUTCOME

Primary: mortality and readmission to hospital, within 365 days follow-up. Secondary: length of stay.

RESULTS

We found no statistically significant differences in mortality and readmission rate between patients in the fast-track and conventional care models within 365 days after the initial hospital admission. The conventional care group had a higher, no statistical significant mortality HR of 1.10 (95% CI 0.91 to 1.31, p=0.326) without and 1.16 (95% CI 0.96 to 1.40, p=0.118) with covariate adjustment. Regarding the readmission, the conventional care group sub-HR was 1.02 (95% CI 0.88 to 1.18, p=0.822) without and 0.97 (95% CI 0.83 to 1.12, p=0.644) with adjusting for covariates. Length of stay and time to surgery was statistically significant shorter for patients who received fast-track care, a mean difference of 3.4 days and 6 hours, respectively. There was no statistically significant difference in sex, type of fracture, age or Charlson Comorbidity Index score at baseline between patients in the two pathways.

CONCLUSIONS

There was insufficient evidence to show an impact of fast-track care on mortality and readmission. Length of stay and time to surgery were decreased.

Hospital mortality after hip fracture surgery in relation to length of stay by care delivery factors: A database study

Two hypotheses were offered for the effect of shorter hospital stays on mortality after hip fracture surgery: worsening the quality of care and shifting death occurrence to postacute settings.We tested whether the risk of hospital death after hip fracture surgery differed across years when postoperative stays shortened, and whether care factors moderated the association.Analysis of acute hospital discharge abstracts for subgroups defined by hospital type, bed capacity, surgical volume, and admission time.153,917 patients 65 years or older surgically treated for first hip fracture.Risk of hospital death.We found a decrease in the 30-day risk of hospital death from 7.0% (95%CI: 6.6-7.5) in 2004 to 5.4% (95%CI: 5.0-5.7) in 2012, with an adjusted odds ratio [OR] 0.71 (95%CI: 0.63-0.80). In subgroup analysis, only large community hospitals showed the reduction of ORs by calendar year. No trend was observed in teaching and medium community hospitals. By 2012, the risk of death in large higher volume community hospitals was 34% lower for weekend admissions, OR = 0.66 (95%CI: 0.46-0.95) and 39% lower for weekday admissions, OR = 0.61 (95%CI: 0.40-0.91), compared to 2004. In large lower volume community hospitals, the 2012 risk was 56% lower for weekend admissions, OR = 0.44 (95%CI: 0.26-0.75), compared to 2004.The risk of hospital death after hip fracture surgery decreased only in large community hospitals, despite universal shortening of hospital stays. This supports the concern of worsening the quality of hip fracture care due to shorter stays.

In-hospital mortality after hip fracture by treatment setting

BACKGROUND

Where patients with hip fracture undergo treatment may influence their outcome. We compared the risk of in-hospital death after hip fracture by treatment setting in Canada.

METHODS

We examined all discharge abstracts from the Canadian Institute for Health Information with diagnosis codes for hip fracture involving patients 65 years and older who were admitted to hospital with a nonpathological first hip fracture between Jan. 1, 2004, and Dec. 31, 2012, in Canada (excluding Quebec). We compared the risk of in-hospital death, overall and after surgery, between teaching hospitals and community hospitals of various bed capacities, accounting for variation in length of stay.

RESULTS

Compared with the number of deaths per 1000 admissions at teaching hospitals, there were an additional 3 (95% confidence interval [CI] 1-6), 14 (95% CI 10-18) and 43 (95% CI 35-51) deaths per 1000 admissions at large, medium and small community hospitals, respectively. For the risk of in-hospital death overall, the adjusted odds ratios (ORs) were 1.05 (95% CI 0.99-1.11), 1.16 (95% CI 1.09-1.24) and 1.44 (95% CI 1.31-1.57) at large, medium and small community hospitals, respectively, compared with teaching hospitals. For the risk of postsurgical death in hospital, the adjusted ORs were 1.06 (95% CI 1.00-1.13), 1.13 (95% CI 1.04-1.23) and 1.18 (95% CI 0.87-1.60) at large, medium and small community hospitals, respectively.

INTERPRETATION

Compared with teaching hospitals, the risk of in-hospital death among patients with hip fracture was higher at medium and small community hospitals, and the risk of in-hospital death after surgery was higher at medium community hospitals. No differences were found between teaching and large community hospitals. Future research should examine the role of volume, demand and bed occupancy for observed differences.

Senior Managed Care System for Hip Fracture in the United States

Background

It is debatable whether a managed care model would affect the quality of care and length of hospital stay in the treatment of hip fractures in elderly patients.

Methods

This prospective study was undertaken to determine whether or not a managed care critical pathway tool shortened hospital stay in a group of 102 senior patients with fractures of the hip during follow-up. We compared our study findings with two equivalent populations of senior hip fracture patients not treated using a critical care pathway concerning specific markers of quality.

Results

The managed care group had a 9% mortality rate, 95% return to prefracture living and 63% return to ambulatory status. The rates compared favorably with previous studies. The quality of care provided before and after the critical pathway was equivalent, while the post-pathway length of stay dropped 30%.

Conclusions

The proposed care protocol is recommended to shorten hospital stay in elderly patients with hip fractures.

Orthopedic complications in diabetes

Diabetes is associated with a number of lower extremity orthopedic conditions and complications including fractures, Charcot neuroarthropathy, plantar ulcers, and infection. These complications are of significant clinical concern in terms of morbidity, mortality, and socioeconomic costs. A review of each condition is discussed, with particular emphasis on the clinical importance, diagnostic considerations, and orthopedic treatment recommendations. The goal of the article is to provide a clinical picture of the challenges that orthopedic surgeons confront, and highlight the need for specific clinical guidelines in diabetic patients.

Mortality following the first hip fracture in Norwegian women and men (1999-2008). A NOREPOS study

Hip fractures are associated with increased mortality and their incidence in Norway is one of the highest worldwide. The aim of this nationwide study was to examine short- and long-term mortality after hip fractures, burden of disease (attributable fraction and potential years of life lost), and time trends in mortality compared to the total Norwegian population. Information on incident hip fractures between 1999 and 2008 in all persons aged 50 years and older was collected from Norwegian hospitals. Death and emigration dates of the hip fracture patients were obtained through 31 December 2010. Standardized mortality ratios (SMRs) were calculated and Poisson regression analyses were used for the estimation of time trends in SMRs. Among the 81,867 patients with a first hip fracture, the 1-year excess mortality was 4.6-fold higher in men, and 2.8-fold higher in women compared to the general population. Although the highest excess mortality was observed during the first two weeks post fracture, the excess risk persisted for twelve years. Mortality rates post hip fracture were higher in men compared to women in all age groups studied. In both genders aged 50 years and older, approximately 5% of the total mortality in the population was related to hip fractures. The largest proportion of the potential life-years lost was in the relatively young-old, i.e. less than 80 years. In men, the 1-year absolute mortality rates post hip fracture declined significantly between 1999 and 2008, by contrast, the mortality in women increased significantly relatively to the population mortality.

Hip fractures in a geriatric population - rehabilitation based on patients needs

With an increased life expectancy in humans and thus an increase in the number of the elderly population, the frequency of hip fractures will rise as well. Aside from a higher incidence, hip fractures in a geriatric population is a significant problem due to the possible onset of severe and in some cases dramatic complications and consequences. The primary purpose of treatment and rehabilitation in the elderly after a hip fracture is to improve an individual's quality of life. It is important to underline that principles and methods of functional restoration after hip fracture should consider careful planning of a rehabilitation program individually for every patient and its implementation with respect to decisions made by the rehabilitation team.

The pathogenesis, treatment and prevention of osteoporosis in men

Testosterone stimulates longitudinal and appositional growth during childhood, whereas estrogen induces epiphysial closure. During adulthood, testosterone continues to stimulate periosteal growth, whereas estrogen is important for the maintenance of trabecular bone mass and structure. In males, testosterone is aromatized to estradiol. Both free and bioavailable plasma levels of testosterone and estradiol decrease with age in males, and fracture risk is associated with low estradiol levels. Testosterone may increase muscle mass and prevent fractures related to falls. Younger hypogonadal males should be treated with testosterone to attain peak bone mass and increase bone mineral density (BMD). Older hypogonadal males should be treated in cases of osteoporosis, reduced muscle strength and increased risk of falling. Secondary hyperparathyroidism caused by calcium and vitamin D insufficiency may reduce bone mass and strength and increase fracture risk and should be avoided. Since calcium supplementation has been associated with an increased risk of cardiovascular complications and renal stones, the dose should be tailored to the habitual daily calcium intake. Lifestyle-related risk factors (smoking, alcohol consumption, lack of physical activity and low body weight) should be addressed. The antifracture efficacy of antiresorptive and anabolic treatment for osteoporosis has not been documented in larger randomized controlled studies. However, changes in BMD and bone markers suggest similar effects in males and females of bisphosphonates (alendronate, risedronate, ibandronate, zoledronic acid), nasal calcitonin, denosumab and teriparatide (parathyroid hormone [1-34]). The antiresorptive drugs should be used in males with BMD T-score less than -2.5 and one or more risk factors, or with hip and vertebral fractures. It seems appropriate to recommend a higher cut-off T-score (e.g. less than -1.0 standard deviation [SD]) in glucocorticoid-induced osteoporosis and in patients receiving androgen deprivation therapy because of the fast initial bone loss. Anabolic treatment should be used in more severe spinal fracture cases, including glucocorticoid-induced osteoporosis.

Health care costs of osteopenia, osteoporosis, and fragility fractures in Mexico

Different sources were used to estimate the 2010 health care costs of managing low bone density (osteopenia/osteoporosis) plus caring fragility fractures in Mexico at 411 million USD. Figures are projected to rise 42 % by 2020. Preventive and timely interventions are required to decrease the financial burden of these entities.

INTRODUCTION

Osteopenia, osteoporosis, and fragility fractures (FF) are a public health concern. The study purpose was to estimate the health care costs of these conditions in Mexico during 2010 and project them to 2015 and 2020.

METHODS

Prevalence of osteopenia and osteoporosis was derived from international data. The Mexican version of FRAX® algorithm was used to assess risk for a major FF (hip, clinical spine, forearm, and proximal humerus) in osteopenic and osteoporotic population aged over 40 years. The estimates were applied to national demographic projections. Only direct medical costs composed by routine non-pharmacological management of osteopenia/osteoporosis besides the costs owing to medical care of major FF were considered into the analysis. Resource use for managing osteopenia/osteoporosis was defined from local sources (clinical practice guidelines, published literature, and expert opinion); unit costs were gathered from official lists. Costs for medical care of FF were based on diagnosis-related groups.

RESULTS

In population aged ≥40 years, prevalence of osteopenia and osteoporosis in 2010 was 32.8 and 8 %, respectively. A total of 75,763 FF occurred that year. Costs of managing osteopenia and osteoporosis were 154.9 million USD, whereas medical costs due to FF reached 256.2 million USD. Therefore, the annual health care costs of these entities in 2010 were 411 million USD. Total costs will be 19.2 % higher in 2015, and by 2020, the figures will have increased by 41.7 %.

CONCLUSIONS

Low bone density entails substantial epidemiological and financial burden in Mexico, and their impact will grow considerably during the next years.

Analysis of the association between bisphosphonate treatment survival in Danish hip fracture patients-a nationwide register-based open cohort study

Bisphosphonate (BP) users have decreased mortality, but this could be due to channeling bias. National healthcare data on hip fracture showed lower mortality in patients who were treated prior to fracture or began treatment after fracture. Reduced mortality after only one prescription filled points to the importance of patient factors.

INTRODUCTION

Use of bisphosphonates has been found to be associated with decreased mortality even when adjusted for sex, frailty, bone mineral density and comorbidity, but BP may chiefly be initiated in patients with osteoporosis whose life expectancy is judged to be good. Our aim was to investigate the association between BP initiated before or after a hip fracture with mortality, and any modifying effects of comorbid conditions and recurrent fracture.

METHODS

This register-based cohort study used prescription and mortality information for Danish patients born ≤1945 experiencing a hip fracture between 1/Jan/1999 and 31/Dec/ 2002 (N = 42,076). Patients who began BP after hip fracture were compared with hip fracture patients who remained alive at the time when their matched index case began treatment.

RESULTS

Patients who used BP prior to their hip fracture (4.6 %) had significantly lower 3-month mortality (adjusted odds ratio, OR, 0.68; 0.59-0.77). Patients who began BP after the fracture (2.6 %) had significantly decreased mortality, both for patients who filled only one prescription (adjusted hazard ratio, HR 0.84; 0.73-0.95) and for patients who filled multiple prescriptions HR 0.73 (0.61-0.88). There was a significant interaction by gender with no significant risk reduction in men.

CONCLUSION

This national dataset shows significantly and substantially improved survival in women who receive BP before or after their hip fracture. However, the observation of a reduction in mortality in patients who filled only one prescription for a BP suggests that patient factors may account for a considerable part of the survival advantage observed with BPs.

Mortality rates after incident non-traumatic fractures in older men and women

Non-traumatic fractures at typical osteoporotic sites are associated with increased mortality across all age groups, particularly in men. Furthermore, in certain age subgroups of women and men, this rate remained elevated beyond 5 years for fractures of the hip, vertebrae, humerus, and other sites.

INTRODUCTION

Increased mortality rates have been documented following non-traumatic hip, vertebral, and shoulder fractures. However, data are lacking as to the duration of excess mortality and whether there is increased mortality following fractures at other sites. We determined mortality up to 15 years following incident fractures at typical osteoporotic sites.

METHODS

Using healthcare databases for the Province of Manitoba, Canada, we identified individuals 50 years and older with an incident non-traumatic fracture between 1986 and 2007. Each fracture case was matched to three fracture-free controls. Generalized linear models were used to test for trends in mortality and to estimate the relative risk for cases after adjusting for co-morbidity and living arrangements.

RESULTS

During the study period, we identified 21,067 incident fractures in men followed by 10,724 (50.1%) deaths and 49,197 incident fractures in women followed by 22,018 deaths (44.8%). Seventy-six percent of the fractures were at sites other than the hip and vertebrae. After adjustment for age, number of co-morbidities, and level of dependence in living arrangements, the risk of death in cases, relative to controls, was increased in both sexes for hip, vertebral, humerus, wrist (in men only), and other fracture sites. Post-fracture mortality was higher in men than women. Relative mortality was the highest in the younger age groups across the spectrum of fracture sites.

CONCLUSIONS

Fractures at typical osteoporotic sites are associated with increased mortality across all age groups, particularly in men. Better understanding of factors associated with increased post-fracture mortality should inform the development of management strategies.

Bilateral oophorectomy versus ovarian conservation: effects on long-term women's health

Bilateral oophorectomy at the time of hysterectomy for benign disease is commonly practiced to prevent the subsequent development of ovarian cancer. Currently, bilateral oophorectomy is performed in 55% of all U.S. women having a hysterectomy, with approximately 300,000 prophylactic oophorectomies performed every year. Observational studies show that estrogen deficiency, resulting from premenopausal or postmenopausal oophorectomy, is associated with higher risks of coronary artery disease, stroke, hip fracture, Parkinsonism, dementia, cognitive impairment, depression, and anxiety. These studies suggest that bilateral oophorectomy may do more harm than good. In women not at high risk for development of ovarian or breast cancer, removing the ovaries at the time of hysterectomy should be approached with caution.
