Abstract
Background Sarcopenia is associated with increased morbidity and mortality. Clinically, sarcopenia can be overlooked, especially in obesity. Sarcopenia diagnostic criteria include muscle mass (MM) and function assessments. Muscle function can be readily assessed in a clinic setting (grip strength, chair stand test). However, MM requires dual-energy X-ray absorptiometry (DXA) Body Composition (BC) or other costly tools, not readily available. Methods Observational cohort pilot study of independently mobile, community dwelling older adults, comparing MM using two office-based, direct-to-consumer bioimpedance (BIA) scales (Ozeri® [manufactured in China] and OMRON® [OMRON HBF-510® Full Body Sensor, Shiokoji Horikawa, Kyoto, Japan] to DXA. The OMRON differs from the Ozeri scale because the OMRON also includes hand sensors. The European Working Group on Sarcopenia in Older People (EWGSOP) DXA or BIA low MM diagnostic cut-offs were used to classify participants as having low or normal MM. Results Fifty participants: 11 men, 39 women. Forty-two completed DXA. Age 75.8 yrs [67-90]. 81% obese based on body fat cut-offs. With DXA [ASM/height2], 15 had low MM. Using BIA [mmass/height2], 7 with Ozeri, and 27 with OMRON, had low MM. Positive predictive value for low MM versus DXA (as the gold standard) for Ozeri was 73.3% and OMRON was 92.8%. Good correlation between BIA scales and DXA for body fat estimates. Conclusions OMRON captured all low MM participants identified by DXA plus all on DXA diagnostic borderline. Prevalence of obesity was high. Clinically, sarcopenic obese is the most difficult phenotype, as obesity masks low muscle mass. Low cost, readily available, direct-to-consumer BIA BC scales, especially with hand sensors, provide immediate, reliable information on muscle and fat mass. This can prompt appropriate investigation and/or intervention for sarcopenia or sarcopenic obesity.

Abstract
COVID-19 infection causes cognitive changes in the acute phase, but also after apparent recovery. Over fifty post (long)-COVID symptoms are described, including cognitive dysfunction ("brain fog") precluding return to pre-COVID level of function, with rates twice as high in females. Additionally, the predominant demographic affected by these symptoms is younger and still in the workforce. Lack of ability to work, even for six months, has significant socio-economic consequences. This cognitive dysfunction is associated with impaired cerebral glucose metabolism, assessed using 18F-fluorodeoxyglucose-positron emission tomography (FDG-PET), showing brain regions that are abnormal compared to age and sex matched controls. In other cognitive conditions such as Alzheimer's disease (AD), typical patterns of cerebral glucose hypometabolism, frontal hypometabolism and cerebellar hypermetabolism are common. Similar FDG-PET changes have also been observed in post-COVID-19, raising the possibility of a similar etiology. Ketone bodies (B-hydroxybutyrate, acetoacetate and acetone) are produced endogenously with very low carbohydrate intake or fasting. They improve brain energy metabolism in the face of cerebral glucose hypometabolism in other conditions [mild cognitive impairment (MCI) and AD]. Long-term low carbohydrate intake or prolonged fasting is not usually feasible. Medium chain triglyceride (MCT) is an exogenous route to nutritional ketosis. Research has supported their efficacy in managing intractable seizures, and cognitive impairment in MCI and AD. We hypothesize that cerebral glucose hypometabolism associated with post COVID-19 infection can be mitigated with MCT supplementation, with the prediction that cognitive function would also improve. Although there is some suggestion that post COVID-19 cognitive symptoms may diminish over time, in many individuals this may take more than six months. If MCT supplementation is able to speed the cognitive recovery, this will impact importantly on quality of life. MCT is readily available and, compared to pharmaceutical interventions, is cost-effective. Research shows general tolerability with dose titration. MCT is a component of enteral and parenteral nutrition supplements, including in pediatrics, so has a long record of safety in vulnerable populations. It is not associated with weight gain or adverse changes in lipid profiles. This hypothesis serves to encourage the development of clinical trials evaluating the impact of MCT supplementation on the duration and severity of post COVID-19 cognitive symptoms.

Abstract
INTRODUCTION Osteoporosis is a major disease state associated with significant morbidity, mortality, and health care costs. Less than half of the individuals sustaining a low energy hip fracture are diagnosed and treated for the underlying osteoporosis. OBJECTIVE A multidisciplinary Canadian hip fracture working group has developed practical recommendations to meet Canadian quality indicators in post hip fracture care. METHODS A comprehensive narrative review was conducted to identify and synthesize key articles on post hip fracture orthogeriatric care for each of the individual sections and develop recommendations. These recommendations are based on the best evidence available today. CONCLUSION Recommendations are anticipated to reduce recurrent fractures, improve mobility and healthcare outcomes post hip fracture, and reduce healthcare costs. Key messages to enhance postoperative care are also provided.

Abstract
Catch a Break (CaB) is a secondary fracture prevention program that uses medical understandings of osteoporosis to assess first fractures and determine appropriateness for secondary fracture prevention. In this study, we interviewed CaB program participants to identify the understandings that patients themselves used to make sense of first fractures and the osteoporosis suggestion as cause. Semi-structured interviews were conducted with female and male participants of the CaB program in Canada. An interpretive practice approach was used to analyze the data. A random sample of 20 individuals, 12 women, and eight men all aged 50 years and over participated. First fractures were produced as meaningful in the context of osteoporosis only for seniors of very advanced age, and for people of any age with poor nutrition. The trauma events that led to a first fracture were produced as meaningful only if perceived as accidents, and having an active lifestyle was produced as beneficial only for mental health and well-being unrelated to osteoporosis. Cultural knowledge shapes, but does not determine, how individuals make sense of their health and illness experiences. Risk prevention program designers should include patients on the design team and be more aware of the presumptive knowledge used to identify individuals at risk of disease.

Abstract
PURPOSE/INTRODUCTION The objective of this study was to describe osteoporosis-related care patterns during the coronavirus disease 2019 (COVID-19) pandemic in Alberta, Canada, relative to the 3-year preceding. METHODS A repeated cross-sectional study design encompassing 3-month periods of continuous administrative health data between March 15, 2017, and September 14, 2020, described osteoporosis-related healthcare resource utilization (HCRU) and treatment patterns. Outcomes included patients with osteoporosis-related healthcare encounters, physician visits, diagnostic and laboratory test volumes, and treatment initiations and disruptions. The percent change between outcomes was calculated, averaged across the control periods (2017-2019), relative to the COVID-19 periods (2020). RESULTS Relative to the average control March to June period, all HCRU declined during the corresponding COVID-19 period. There was a reduction of 14% in patients with osteoporosis healthcare encounters, 13% in general practitioner visits, 9% in specialist practitioner visits, 47% in bone mineral density tests, and 13% in vitamin D tests. Treatment initiations declined 43%, 26%, and 35% for oral bisphosphonates, intravenous bisphosphonates, and denosumab, respectively. Slight increases were observed in the proportion of patients with treatment disruptions. In the subsequent June to September period, HCRU either returned to or surpassed pre-pandemic levels, when including telehealth visits accounting for 33-45% of healthcare encounters during the COVID periods. Oral bisphosphonate treatment initiations remained lower than pre-pandemic levels. CONCLUSIONS This study demonstrates the COVID-19 pandemic and corresponding public health lockdowns further heightened the "crisis" around the known gap in osteoporosis care and altered the provision of care (e.g., use of telehealth and initiation of treatment). Osteoporosis has a known substantial care and management disparity, which has been classified as a crisis. The COVID-19 pandemic created additional burden on osteoporosis patient care with healthcare encounters, physician visits, diagnostic and laboratory tests, and treatment initiations all declining during the initial pandemic period, relative to previous years.

Abstract
Fragility fractures (i.e., low-energy fractures) account for most fractures among older Canadians and are associated with significant increases in morbidity and mortality. Study results suggest that low-energy fracture rates (associated with surgical intervention and outcomes) declined slightly, but largely remained stable in the first few months of the COVID-19 pandemic. PURPOSE/INTRODUCTION This study describes rates of low-energy fractures, time-to-surgery, complications, and deaths post-surgery in patients with fractures during the coronavirus disease (COVID-19) pandemic in Alberta, Canada, compared to the three years prior. METHODS A repeated cross-sectional study was conducted using provincial-level administrative health data. Outcomes were assessed in 3-month periods in the 3 years preceding the COVID-19 pandemic and in the first two 3-month periods after restrictions were implemented. Patterns of fracture- and hospital-related outcomes over the control years (2017-2019) and COVID-19 restrictions periods (2020) were calculated. RESULTS Relative to the average from the control periods, there was a slight decrease in the absolute number of low-energy fractures (n = 4733 versus n = 4308) during the first COVID-19 period, followed by a slight rise in the second COVID-19 period (n = 4520 versus n = 4831). While the absolute number of patients with low-energy fractures receiving surgery within the same episode of care decreased slightly during the COVID-19 periods, the proportion receiving surgery and the proportion receiving surgery within 24 h of admission remained stable. Across all periods, hip fractures accounted for the majority of patients with low-energy fractures receiving surgery (range: 58.9-64.2%). Patients with complications following surgery and in-hospital deaths following fracture repair decreased slightly during the COVID-19 periods. CONCLUSIONS These results suggest that low-energy fracture rates, associated surgeries, and surgical outcomes declined slightly, but largely remained stable in the first few months of the pandemic. Further investigation is warranted to explore patterns during subsequent COVID-19 waves when the healthcare system experienced severe strain.

Abstract
Introduction Cerebral glucose and insulin metabolism is impaired in Alzheimer's disease (AD). Ketones provide alternative energy. Will medium chain triglyceride (MCT) oil, a nutritional source of ketones, impact cognition in AD? Methods This was a 6‐month randomized, double‐blind, placebo‐controlled, crossover study, with 6‐month open‐label extension in probable AD subjects, on stable medications. MCT dose was 42 g/day, or maximum tolerated. Cognition was assessed with Mini‐Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), and Cognigram®. Results Twenty subjects, average age 72.6 years, 45% women, 70% university educated had baseline MMSE 22.6/30 (10–29); MoCA 15.6/30 (4–27); baseline Cognigram® Part 1: 65–106, Part 2: 48–107. Average MCT oil consumption was 1.8 tablespoons/day (25.2 g, 234 kcal). Eighty percent remained stable or improved. Longer MCT exposure and age > 73, resulted in higher final MMSE (P < .001) and Cognigram® 1 scores. Discussion This is the longest duration MCT AD study to date. Eighty percent had stabilization or improvement in cognition, and better response with 9‐month continual MCT oil.

Abstract
Objectives, Design, Setting: The ketogenic effect of medium chain triglyceride (MCT) oil offers potential for Alzheimer's disease prevention and treatment. Limited literature suggests a linear B-hyroxybutyrate (BHB) response to increasing MCT doses. This pharmacokinetic study evaluates factors affecting BHB response in three subject groups. PARTICIPANTS Healthy subjects without cognitive deficits <65years, similarly healthy subjects >=65years, and those with Alzheimer's Disease were assessed. INTERVENTION Different doses (0g,14g, 28g, 42g) of MCT oil (99.3% C8:0) were administered, followed by fasting during the study period. MEASUREMENTS BHB measured by finger prick sampling hourly for 5 hours after ingestion. Each subject attended four different days for each ascending dose. Data was also collected on body composition, BMI, waist/hip ratio, grip strength, gait speed, nutrient content of pre-study breakfast and side effects. RESULTS Twenty-five participants: eight healthy; average age of 44yr (25-61), nine healthy; 79yr (65-90) and eight with AD; 78.6yr (57-86) respectively. Compiled data showed the expected linear dose response relationship. No group differences, with baseline corrected area under the blood vs. time curve (r2=0.98) and maximum concentrations (r2=0.97). However, there was notable individual variability in maximum BHB response (42g dose: 0.4 -2.1mM), and time to reach maximum BHB response both, within and between individuals. Variability was unrelated to age, sex, sarcopenic or AD status. Visceral fat, BMI, waist/hip ratio and pretest meal CHO and protein content all affected the BHB response (p<0.001). CONCLUSION There was a large inter-individual variability, with phenotype effects identified. This highlights challenges in interpreting clinical responses to MCT intake.

Abstract
UNLABELLED Catch a Break staff conducting the organizational work of delivering secondary fracture prevention screening conversations drew on cultural and organizational resources to determine eligibility of individuals. They encountered and navigated their way through interactional troubles as they requested participation, assessed trauma risk, and provided lifestyle information. PURPOSE We investigated delivery of a population-based type C fracture liaison service for non-hip fractures. The purpose of this study was to examine accounts of how osteoporosis health risk screening interactions were delivered. METHODS A pre-determined sample of 5 organizational representatives (program staff) were interviewed by telephone. We analyzed the qualitative data through the lens of interpretive inquiry, informed by discourse analysis, to examine staff's "talk" about conducting the program risk screening conversations. RESULTS A dominant finding emerging from CAB staff's accounts of program delivery was the conversational work required to include only those individuals deemed appropriate for the program while managing the survey interaction. Staff talked about specific examples of interactional troubles they experienced as barriers to the smooth and successful risk screening conversation. They drew on cultural and organizational resources as interpretive frameworks to make decisions about individuals and groups at risk and in need of further investigation. They drew on larger ideas about ageism and genderism, judging as inappropriate for participation the oldest old adults, men involved in high risk occupations, and adults aged 50 to 70. Staff also employed interactional resources useful in managing problems in the conversation during the request to participate, trauma risk assessment, and lifestyle/health information provision sequences of the risk screening call. CONCLUSION We uncovered areas in the screening interaction that were talked about by staff as problematic to achieving the program objective of identifying and enrolling individuals in the secondary fracture prevention program. By highlighting areas for improvement in program delivery, this study may help to reduce the interactional troubles staff negotiate as they deliver this type of program.

Abstract
UNLABELLED The scorecard evaluates the burden and management of osteoporosis in Canada and how care pathways differ across Canadian provinces. The results showed there are inequities in patients' access to diagnosis, treatment, and post-fracture care programs in Canada. Interventions are needed to close the osteoporosis treatment gap and minimize these inequities. INTRODUCTION The purpose of this study was to develop a visual scorecard that assesses the burden of osteoporosis and its management within Canada and seven Canadian provinces. METHODS We adapted the Scorecard for Osteoporosis in Europe (SCOPE) to score osteoporosis indicators for Canada and seven provinces (British Columbia, Alberta, Saskatchewan, Ontario, Quebec, New Brunswick, and Newfoundland). We obtained data from a comprehensive literature review and interviews with osteoporosis experts. We scored 20 elements across four domains: burden of disease, policy framework, service provision, and service uptake. Each element was scored as red, yellow, or green, indicating high, intermediate, or low risk, respectively. Elements with insufficient data were scored black. RESULTS Canada performed well on several elements of osteoporosis care, including high uptake of risk assessment algorithms and minimal wait times for hip fracture surgery. However, there were no established fracture registries, and reporting on individuals with high fracture risk who remain untreated was limited. Furthermore, osteoporosis was not an official health priority in most provinces. Government-backed action plans and other osteoporosis initiatives were primarily confined to Ontario and Alberta. Several provinces (Saskatchewan, New Brunswick, Newfoundland) did not have any registered fracture liaison service (FLS) programs. Access to diagnosis and treatment was also inconsistent and reimbursement policies did not align with clinical guidelines. CONCLUSION Government-backed action plans are needed to address provincial inequities in patients' access to diagnosis, treatment, and FLS programs in Canada. Further characterization of the treatment gap and the establishment of fracture registries are critical next steps in providing high-quality osteoporosis care.

Abstract
UNLABELLED A hip fracture liaison service that was implemented in 2 hospitals in Alberta, Canada, co-managed by a nurse and physician, was effective for improving initiation of osteoporosis medication following hip fracture. PURPOSE To examine implementation of an in-patient hip fracture liaison service (H-FLS) to improve osteoporosis medication use after hip fracture using the RE-AIM framework (reach, effectiveness, adoption, implementation, maintenance). METHODS Using population-based administrative data from 7 quarters before and up to 7 quarters after H-FLS implementation, we examined new starts, continued use, and overall use (new starts + continued use) of osteoporosis medication after hip fracture. A total of 1427 patients 50 years and older that underwent hip fracture surgery at 1 of 2 tertiary hospitals in a Canadian province and survived to 12 months post-fracture were included. We also compared treatment initiation rates by sex and hospital. RESULTS Of the 1427 patients, 1002 (70.2%) were female (mean age = 79.3 ± 11.9 years) and 425 (29.8%) were male (mean age = 73.8 ± 13.8 years). Based on pre-fracture residence within the health zone, 1101 (69%) were considered eligible (Reach). New starts of osteoporosis medication increased from 24.7% pre- to 43.9% post-implementation of the H-FLS (p < 0.001) (effectiveness). The proportion of patients prescribed osteoporosis medication prior to a hip fracture remained consistent (15.1% pre-; 14.7% post-implementation; p = 0.88) with a resultant improvement in overall medication use from 39.8% pre- to 58.6% post-implementation (p < 0.001). Both sites significantly improved medication initiation (site 1: 27.9% pre- to 40.3% post-implementation; site 2: 19.6% pre- to 50.0% post-implementation; p < 0.001 for both) (adoption). Medication initiation in females improved from 26.0% pre- to 43.4% post-implementation while initiation in males improved from 21.7% pre- to 45.1% post-implementation (p < 0.001[females]; p = 0.001[males]) (implementation). Post-implementation, elevated initiation rates were retained over the 7 quarters (p = 0.81) (maintenance). CONCLUSIONS An H-FLS based in two tertiary hospital sites significantly improved use of osteoporosis medications after hip fracture in both males and females.

Abstract
BACKGROUND Malnutrition and sarcopenia are common in older adults. A new clinical syndrome has been suggested - the Malnutrition Sarcopenia Syndrome (MSS) - that may provide improved management, by highlighting two older adult conditions that can interact in a cumulative way to affect functional independence and health outcomes. This paper evaluates the published literature reporting data on both nutrition and sarcopenia evaluation simultaneously in the population studied, and creates a diagnostic algorithm. METHODS An inclusive, systematic literature search was done for articles including a simultaneous standardised evaluation of sarcopenia and nutritional status, from 1990-date. Sarcopenic status needed to be evaluated using accepted guidelines published by international guideline committees which include a functional muscle evaluation and a quantitative evaluation using bioimpedence assay or dual energy X-ray absorptiometry. Nutritional status needed to evaluated with a standardised, validated nutritional screening tool that was not disease specific. RESULTS 11 studies met these criteria. They differed in their methodology for screening both sarcopenia and nutritional issues. They differed as to the population studied (community versus institutionalised versus hospitalised). CONCLUSIONS No one methodology was consistent for evaluation of sarcopenia or malnutrition. The concept of the Malnutrition Sarcopenia Syndrome intuitively makes sense to clinicians. This opinion paper suggests a possible clinical approach. The management and interventions for both conditions are likely to have considerable overlap. There needs to be some consensus on how to evaluate it, in order to be able to accurately interpret the impact of interventions that may be undertaken for one or both conditions simultaneously.

Abstract
UNLABELLED Fracture liaison services (FLS) are advocated to improve osteoporosis treatment after fragility fracture, but there are few economic analyses of different models. A population-based 1i [=type C] FLS for non-hip fractures was implemented and it costs $44 per patient and it was very cost-effective ($9200 per QALY gained). Small operational changes would convert it from cost-effective to cost-saving. INTRODUCTION After fragility fracture, <20% of patients receive osteoporosis treatment. FLS are recommended to address this deficit but there are very few economic analyses of different FLS models. Therefore, we conducted an economic analysis of a 1i (=type C) FLS called "Catch a Break (CaB)." METHODS CaB is a population-based FLS in Alberta, Canada, that case-finds older outpatients with non-traumatic upper extremity, spine, pelvis, or "other" non-hip fractures and provides telephonic outreach and printed educational materials to patients and their physicians. Cost-effectiveness was assessed using Markov decision-analytic models. Costs were expressed in 2014 Canadian dollars and effectiveness based on model simulations of recurrent fractures and quality-adjusted life years (QALYs). Perspective was healthcare payer; horizon was lifetime; and costs and benefits were discounted 3%. RESULTS Over 1 year, CaB enrolled 7323 outpatients (mean age 67 years, 75% female, 69% upper extremity) at average cost of $44 per patient. Compared with usual care, CaB increased rates of bisphosphonate treatment by 4.3 to 17.5% (p < 0.001). Over their lifetime, for every 10,000 patients enrolled in CaB, 4 hip fractures (14 fractures total) would be avoided and 12 QALYs gained. Compared with usual care, incremental cost-effectiveness of CaB was estimated at $9200 per QALY. CaB was cost-effective in 85% of 10,000 probabilistic simulations. Sensitivity analyses showed if "other" fractures were excluded and intervention costs reduced 25% that CaB would become cost-saving. CONCLUSIONS A relatively inexpensive population-based 1i (=type C) FLS was implemented in Alberta and it was very cost-effective. If CaB excluded "other" fractures and decreased intervention costs by 25%, it would be cost-saving, as would any FLS that was more effective and less expensive.

Abstract
Thyroid disease is common, and the prevalence is rising. Traditional diagnosis and monitoring relies on thyroid stimulating hormone (TSH) levels. This does not always result in symptomatic improvement in hypothyroid symptoms, to the disappointment of both patients and physicians. A non-traditional therapeutic approach would include evaluation of GI function as well as a dietary history and micronutrient evaluation. This approach also includes assessment of thyroid peroxidase (TPO) antibodies, T3, T4, and reverse T3 levels, and in some cases may require specific T3 supplementation in addition to standard T4 therapy. Both high and low TSH levels on treatment are associated with particular medical risks. In the case of high TSH this is primarily cardiac, whereas for low TSH it is predominantly bone health. This article discusses these important clinical issues in more detail, with some practical tips especially for an approach to the "non-responders" to the current traditional therapeutic approach.

Abstract
Subtrochanteric atypical femoral fractures (AFFs) have been reported in patients on osteoporosis therapy (bisphosphonates and denosumab). In 2010, and again in 2013, the ASBMR AFF Task Force developed strict diagnostic criteria for AFFs. This is the first study using these criteria to define the prevalence of AFFs in Canada. This study is a retrospective review of all adult patients (April 2002-March 2013) with an ICD 10 code for hip, femoral or subtrochanteric fracture, from two referral hospitals in Alberta, Canada. All identified as isolated subtrochanteric fractures were further evaluated by chart review, prescription review and examination of radiographs. Of 349 subjects, 79 had isolated subtrochanteric fractures. Of the 70 cases of subtrochanteric fractures that were radiographically assessed (9 films unavailable), 41 fulfilled ASBMR 2013 AFF criteria. The remaining subjects had subtrochanteric fractures but did not meet the ASBMR criteria to qualify as AFFs. There were 11 AFFs in 2012/2013, giving a rate of AFFs of 1.42 per 100,000 50 + year adults, compared to a rate of 103.47 per 100,000 50+ year adults for typical hip fractures. Isolated subtrochanteric fractures are rare. They cannot reliably be identified by ICD coding alone. In this study, only 59 % of all isolated subtrochanteric/femoral shaft fractures fulfilled the ASBMR task force criteria for true AFFs. The rate of typical hip fractures was substantially higher than the rate of AFFs, defined by ASBMR diagnostic criteria.

Abstract
UNLABELLED Intravenous bisphosphonates reduce mortality following hip fracture. We determined whether new use of oral bisphosphonates was also associated with reductions in mortality in 209 hip fracture patients. Oral bisphosphonate exposure led to relative reduction of 8% per month of use (p = 0.001) or about a 60% reduction in mortality per year of use. INTRODUCTION Intravenous bisphosphonates reduce mortality following hip fracture. Using prospectively collected long-term data from a randomized trial of osteoporosis quality improvement for hip fracture, we determined whether new use of oral bisphosphonates was associated with reductions in mortality or the composite outcome of death or new fracture. METHODS Originally, 220 hip fracture patients were randomized to case manager (n = 110) or usual care followed by facilitated bone mineral density (BMD) testing (n = 110) interventions. All were eligible for bisphosphonate treatment. Post-randomization, we followed patients for 3 years and ascertained bisphosphonate treatment, medication adherence and persistence, all-cause mortality, and new clinical fractures. Proportional hazards analyses with time-varying treatment status were undertaken. RESULTS The final study cohort included 209 patients: 136 (65%) females, 104 (50%) older than 75 years, 90 (43%) with poor self-reported health, and 38 (18%) underweight. Of these, 76 (36%) had a previous fracture before hip fracture and 132 (81%) had low BMD. A total of 101 (46%) patients started oral bisphosphonates and 65 (64%) remained on treatment at the final evaluation. Overall, 24 (11%) patients died, 19 (9%) had new fractures, and 42 (20%) reached the composite outcome of death or fracture. Compared to no treatment, bisphosphonate exposure was independently associated with reduced mortality (17[16%] vs. 7[7%]; adjusted hazard ratio (aHR) = 0.92 per month treated; 95%CI, 0.88-0.97) and composite endpoints (28[26%] vs. 5[15%]; aHR = 0.94 per month treated; 95%CI, 0.91-0.97). CONCLUSION Like intravenous bisphosphonates after hip fracture, our study suggests that oral bisphosphonates may be associated with reductions in all-cause mortality.

Abstract
OBJECTIVE We previously demonstrated that a case manager intervention improved osteoporosis (OP) treatment within 6 months of hip fracture compared with usual care. The second phase of the randomized trial compared a less intensive intervention, facilitated bone mineral density (BMD) testing, with usual care and the case manager intervention. METHODS We initially randomized 220 hip fracture patients to either an OP case manager intervention or usual care. After completing the original trial at 6 months postfracture, usual care patients were reallocated to facilitated BMD testing; BMD tests were arranged and results sent to primary care physicians. Main outcomes (bisphosphonate treatment, BMD tests, receipt of appropriate care) were reascertained 1 year following hip fracture and compared with outcomes achieved by the OP case manager intervention and usual care. RESULTS Compared with usual care, facilitated BMD testing increased testing from 29% to 68% (P < 0.001), bisphosphonate use from 22% to 38% (P < 0.001), and receipt of appropriate care from 26% to 45% (P < 0.001). The more intensive (70 versus 30 minutes) and expensive ($56 versus $24 Canadian per patient) OP case manager intervention led to significantly higher bisphosphonate use (54% versus 38%; P = 0.03), receipt of appropriate care (71% versus 45%; P < 0.001), and more BMD testing (80% versus 68%; P = 0.06) than usual care followed by facilitated BMD testing. CONCLUSION Compared with usual care, 2 different inexpensive interventions resulted in significant increases in appropriate management of OP after hip fracture. The magnitude of improvements achieved was directly related to the intensity of the interventions.

Abstract
Efficacy of hip protector pads to prevent hip fracture is controversial. This study was done to evaluate two comparable groups for fracture risk. Two matched cohorts of long-term care residents in Canada, assessing the efficacy of hip protector pads. Evaluation included demographics, medications/diagnoses, cognition (Mini Mental Status Examination (MMSE)), balance (Berg), bone mineral density (calcaneal ultrasound), falls/injuries at baseline and completion. Of the 58 participants, there were two confirmed hip fractures (8%) in the hip pad (one while wearing the pad) and eight (24%) in the control groups. But baseline demographics showed significant differences between hip pad (25) and control groups (33) in MMSE, Berg and osteoporosis treatment, all being less in the hip pad group. This persisted at completion, with a higher mortality in the hip pad group. Baseline differences predisposed the hip pad group to a higher fracture risk, but there were fewer hip fractures in this group. Small numbers, multifactorial nature of hip fractures and the inability to control for many of these variables in the real world make efficacy of hip protector pads difficult to confirm. Hip protector pads should be offered as part of the osteoporosis management of frail elderly, especially in those unable/unwilling to take pharmacotherapy.

Abstract
BACKGROUND Patients who survive hip fracture are at high risk of recurrent fractures, but rates of osteoporosis treatment 1 year after sustaining a fracture are less than 10% to 20%. We have developed an osteoporosis case manager intervention. The case manager educated patients, arranged bone mineral density tests, provided prescriptions, and communicated with primary care physicians. The intervention was compared with usual care in a randomized controlled trial. METHODS We recruited from all hospitals that participate in the Capital Health system (Alberta, Canada), including patients 50 years or older who had sustained a hip fracture and excluding those who were receiving osteoporosis treatment or who lived in a long-term care facility. Primary outcome was bisphosphonate therapy 6 months after fracture; secondary outcomes included bone mineral density testing, appropriate care (bone mineral density testing and treatment if bone mass was low), and intervention costs. RESULTS We screened 2219 patients and allocated 220, as follows: 110 to the intervention group and 110 to the control group. Median age was 74 years, 60% were women, and 37% reported having had previous fractures. Six months after hip fracture, 56 patients in the intervention group (51%) were receiving bisphosphonate therapy compared with 24 patients in the control group (22%) (adjusted odds ratio, 4.7; 95% confidence interval, 2.4-8.9; P < .001). Bone mineral density tests were performed in 88 patients in the intervention group (80%) vs 32 patients in the control group (29%) (P < .001). Of the 120 patients who underwent bone mineral density testing, 25 (21%) had normal bone mass. Patients in the intervention group were more likely to receive appropriate care than were patients in the control group (67% vs 26%; P < .001). The average intervention cost was $50.00 per patient. CONCLUSION For a modest cost, a case manager was able to substantially increase rates of osteoporosis treatment in a vulnerable elderly population at high risk of future fractures.

Abstract
The objective of this study was to evaluate the knowledge, awareness, utilization, and satisfaction of patients with different treatment modalities for osteoarthritis (OA). Patients with a diagnosis of OA of the knee or hip who had attended a rheumatology referral clinic over the preceding 2 years were eligible. A six-page self-administered questionnaire was mailed to them. Responses were anonymous. One hundred and six completed questionnaires were returned. The average age of the respondents was 64 years and included 71 females. Ninety-four percent of respondents had at least 8 years of formal education, and 75% had had OA for at least 5 years. Seventy-five percent successfully defined OA. The majority had heard of most treatment modalities. Seventy-one percent had tried cyclooxygenase-2 inhibitors (COXIBs), 79% analgesics, and 56% physiotherapy. Twenty-six percent had had surgery for their OA. Of those that had tried the various treatment options, the most satisfaction occurred with surgery, pool therapy, walking aids, and narcotic analgesics. Fifty-five percent found traditional nonsteroidal anti-inflammatory drugs (NSAIDs) helpful and 65% benefited from the COXIBs. Treatment reported as providing the most improvement in function was surgery, followed by steroid injections, COXIB therapy, and traditional NSAIDs. Treatment modalities providing the most symptomatic improvement were surgery, followed by COXIBs and steroid injections. When treatment options were compared, their rank ordering differed when considering overall satisfaction, functional improvement, and symptomatic relief. The participants in this study were well informed as to the nature of their disease and its treatment. A wide number of therapies had been tried, most of which were well tolerated. According to patient perception, those undergoing surgical treatment had the best improvement in symptoms and function. For those using anti-inflammatories (NSAIDs or COXIBs) improvement occurred in >50%, though this was less than for physiotherapy and analgesics. Based on this cohort of patients, treatments that were rated highly (such as surgery) were not necessarily those that were the most widely experienced. Conversely, those therapies that were the most widely accessed (such as analgesics) were not necessarily those that provided the maximum perceived benefit. We conclude that in the continued absence of specific disease-modifying therapies for OA, multiple therapeutic options need to be explored to address individual patient's functional and symptomatic needs.

Abstract
OBJECTIVES Low bone mineral density (BMD) is a major risk factor for osteoporotic fracture. The gold standard measurement of BMD, central dual-energy x-ray absorptiometry (DXA), requires transportation to a radiologic facility, patient agility and cooperation. For those with severe cognitive impairment, this is not realistic; hence, central BMD is seldom measured. The objectives were to evaluate the use of calcaneal BMD measurement (by qualitative ultrasound), the prevalence of osteoporosis diagnosis (based on calcaneal BMD), and treatment in individuals with severe cognitive impairment. DESIGN This is a point prevalence descriptive study. Calcaneal BMD was measured using a Sahara sonometer (Hologic). Cognition (Mini Mental Status Examination), mobility (Berg balance scale, timed up-and-go), and chart audit were also undertaken. SETTING This study was conducted at four dementia long-term care facilities (122 beds) in Edmonton, Alberta, Canada. PARTICIPANTS Forty long-term care residents participated in this study with an average MMSE of 10 (range, 0-25). MEASUREMENTS One hundred percent of study subjects cooperated with calcaneal ultrasound measurement. RESULTS Based on calcaneal BMD measurement using recommended cutoffs, 92.5% were at high risk for osteoporosis or osteopenia and 5% were at moderate risk. One participant (2.5%) had a normal calcaneal BMD measurement. Calcium supplementation occurred in 32% of the high-risk group, 50% of the moderate-risk group, and 100% of the normal group. One (2.5%) participant was on hormone replacement therapy, and 12% were taking etidronate. CONCLUSIONS Calcaneal ultrasound measurement could be a useful tool to assess BMD in cognitively impaired nursing home residents.

Abstract
As the population ages, and there is more pressure on acute and long-term care services, governments will continue to search for ways to save healthcare dollars. Home care has been touted as an alternative to long-term care; however, not enough is known about quality of care and patient outcomes.

Abstract
This study examined post-fracture osteoporosis drug treatment in hip fracture patients and the association of treatment with mortality and morbidity. Pre- and post-fracture demographic/health information was collected on a cohort of hip fracture patients aged 65+ years. Post-fracture administrative data on prescription drug use and health care utilization was linked to the cohort data. Five classes of osteoporosis drugs were available during the study period: hormone replacement therapy (HRT), bisphosphonates (BSP), calcitonin, selective estrogen receptor modulators (SERMs) and vitamin D(3) (Rocaltrol). Pre-fracture, 38 of 449 patients (8%) were on osteoporosis medications. Post-fracture, 81 of 356 patients (23%) were treated; 63 of these patients were untreated prior to fracture. Both treated and untreated patients had similar rates of subsequent hip fracture (6% and 4%, respectively) and Colles fracture (2%). Regardless of treatment status, patients were also equally likely to be hospitalized, both in the short-term (28% in treated, 27% in untreated) and in the long-term (43% versus 37%). However, mortality was significantly lower in the treated group. The lower mortality in the treated group, combined with the knowledge that antiresorptive drugs reduce fractures and increase bone density, merit undertaking a randomized trial to confirm our findings that antiresorptive therapy should be considered in all patients post-hip fracture.

Abstract
A retrospective chart review was carried out on all consecutive patients over 65 years of age admitted to a tertiary care teaching hospital with a diagnosis of a new hip fracture. A further chart review occurred after discharge from post-surgery rehabilitation. The primary objective was to evaluate the prevalence of osteoporosis diagnosis and treatment in both phases of the study. Secondary objectives included evaluation of the mortality rates, length of stay, prevalence of osteoporosis investigation, and prevalence of osteoporosis diagnosis based on the clinical subspecialty involved. There were 311 patients evaluated in the initial phase, and 226 after rehabilitation. The mortality rate was 5.8% (10% for men, 4% for women; p<0.005) in the acute care hospital and 9.3% (8% men, 10% women) during rehabilitation. Previous hip fracture occurred in 17.4%, and 1.5% were readmitted during the study period with fracture of the opposite hip. Osteoporosis was diagnosed in the acute care hospital on admission in 11.9% and on discharge in 15.4%. In the rehabilitation hospital it was diagnosed in 9.7% on admission and 11.2% on discharge (p=NS). Osteoporosis treatment (including calcium or vitamin D therapy) was instituted in 13% on admission to acute care and in 9.7% at the time of discharge. For the rehabilitation hospital, treatment occurred in 12.8% on admission and 10.2% on discharge. The diagnosis of osteoporosis significantly increased the prevalence of treatment (p<0.001). Use of specific agents (hormone replacement therapy, bisphosphonates or calcitonin) occurred in <66% of all patients. Osteoporosis is under-diagnosed and under-treated in this group of elderly hip fracture patients. It is associated with significant mortality and morbidity and every effort should be made to prevent future fractures. Physicians in the 'front line' of hip fracture treatment are missing this key aspect of management in their patients. Education of these physicians, as well as the public, may be the key to addressing this care gap.

Abstract
This was a prospective cohort study of 145 seniors attending a senior's clinic and social day program using a self-administered questionnaire. Its objective was to evaluate the awareness, knowledge, risk factors and current treatment of osteoporosis in our two patient groups. A secondary objective was to determine differences between the two cohorts, and between men and women. Participants included 39 men and 106 women, with an average age of 76 years. Of these, 89% were aware of osteoporosis and 61% gave the correct definition. Awareness and accurate definition were less in men compared with women (p < 0.01, and p < 0.05) and clinic compared to day program groups (p < 0.01). Only 54% of men knew osteoporosis could affect them. Television, newspapers and friends were identified as the main source of information. Physicians ranked as fifth as a source of information. In all, 84% knew diet was important. Prevalence of risk factors other than age were < 20%, except for senescence (38%) and alcohol use (40%). Utilization of specific therapies for osteoporosis was only 18% overall with a rate of 3% in men (p < 0.01). In women, 50% and were taking calcium supplements compared with 15% men (p < 0.001) and for multivitamins the figures were 57% and 33% respectively (p < 0.05). These results show a high level of awareness and correct definition of osteoporosis in this cohort of patients. Specific therapy for prevention or treatment of osteoporosis was inappropriately low in the face of high risk. This study highlights the care gap in osteoporosis in seniors and the need for increased physician involvement in patient education and treatment. Proactive treatment requests from patients need to be encouraged, especially with the future demographic shift.

Abstract
OBJECTIVE To determine the prevalence and association with various diseases of certain autoantibodies among elderly patients, in order to challenge the hypothesis that these autoantibodies are elevated generally in these patients as a result of immunosenescence. DESIGN Prospective prevalence study. PATIENTS A total of 399 elderly patients: 63 aging successfully (without chronic illness), 301 with a variety of chronic general illnesses (frail elderly) and 35 with a clinical diagnosis of rheumatoid arthritis. These were compared with 250 healthy adult blood donors. INTERVENTIONS Measurement of autoantibodies to rheumatoid factor, antinuclear antibody, double-stranded (native) DNA (nDNA), extractable nuclear antigens and anticardiolipin antibodies. OUTCOME MEASURES Prevalence of these autoantibodies and correlation with disease states. RESULTS Antibodies to rheumatoid factor and antinuclear antibody were significantly more prevalent in the elderly patients with chronic illness or rheumatoid arthritis but were not disease-specific. The prevalence of nDNA and extractable nuclear antigens was not increased in either the healthy or frail elderly groups. Anticardiolipin antibodies were significantly more prevalent in the frail elderly group when compared with normal controls and the healthy elderly group. The prevalence of anticardiolipin antibodies correlated with clinical features of cerebrovascular disease, in particular multi-infarct dementia and stroke, but not with Alzheimer's disease. CONCLUSIONS The prevalence of the autoantibodies measured was not elevated in healthy elderly subjects, and autoantibodies such as nDNA and extractable nuclear antigens are specific to disease states in all groups of elderly patients. Anticardiolipin antibodies correlate with cerebrovascular events. Therefore, the clinical significance of autoantibodies in elderly patients is related more to global health status than to the effects of aging.

Abstract
We have evaluated the prevalence of selected autoantibodies commonly utilized in rheumatologic practice in different elderly subpopulations grouped according to their clinical status. RF, ANA, double-stranded DNA antibodies, and antibodies to extractable nuclear antigens (ENA) were measured in the serum of all participants using standardized laboratory assays. One hundred and fifty-nine elderly subjects were enrolled, of whom 63 were classified as successfully aging elderly, 62 were ambulatory chronically ill residents of a nursing or Veterans home and 34 were patients attending an RA clinic. Prevalence of autoantibodies were compared to healthy adult blood donors. There was no statistically significant increase in autoantibodies in successfully aging elderly compared to healthy young controls. RF, ANA and ENA antibodies were significantly increased in only the chronically ill and RA sufferers. Antibodies to nDNA were absent in all groups. We conclude that autoantibodies commonly utilized in rheumatological practice are not globally non-specifically increased as a result of aging, but increase in prevalence in chronically ill elderly. Therefore assessment of health status is necessary to evaluate the clinical significance of these autoantibodies in the elderly.
