Ten existing osteoporosis prediction tools for the successful application of National Health Insurance-reimbursed anti-osteoporosis medications in long-term care residents in Taiwan. J Formos Med Assoc 2023; 122:139-147. [PMID: 36041990 DOI: 10.1016/j.jfma.2022.08.009] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Revised: 07/01/2022] [Accepted: 08/09/2022] [Indexed: 02/01/2023]
Abstract
BACKGROUND/PURPOSE Osteoporotic fracture introduce enormous societal and economic burden, especially for long-term care residents (LTCRs). Although osteoporosis prevention for LTCRs is urgently needed, obstacles such as frail status and inconvenient hospital visits hurdled them from necessary examinations and diagnoses. We aimed to test 10 existing osteoporosis screening tools (OSTs), which can be easily used in institutions and serve as a prediction, for accurately determining the outcome of a Taiwan's National Health Insurance (NHI)-reimbursed anti-osteoporosis medications (AOMs) application for LTCRs. METHODS This prospective analysis recruited 444 patients from LTC institutions between October 2018 and November 2019. Predictions of whether the NHI-reimbursed AOMs criteria was met were tested for 10 OSTs. The results of OSTs categorized into self-reported or validated based on previous fracture history were self-reported by LTCRs or validated by imaging data and medical records, respectively. The receiver operating characteristic curve and the optimal cut-off points for LTCRs based on Youden's index were explored. RESULTS Overall, the validated OSTs had a higher positive predictive value (PPV) and negative predictive value (NPV) summation than the corresponding reported OSTs. The validated FRAX-Major was the best OST (PPV = 63.6%, NPV = 82.4% for the male group and, PPV = 78.8%, NPV = 90.0% for the female group). After applying the optimum cut-off derived from Youden's index, the validated FRAX-Major (PPV = 75.4%, NPV = 92.0%)) remained performed best for men. In female population, validated FRAX-Major (PPV = 87.2%, NPV = 84.1%) and validated osteoporosis prescreening risk assessment (OPERA; PPV = 96.1%, NPV = 79.7%)) both provided good prediction results. CONCLUSION FRAX-Major and OPERA have better prediction ability for LTCRs to acquire NHI-reimbursed AOMs. The validated fracture history and adjusted cut-off points could prominently increase the PPV during prediction.

Robison B, Wright C, Smith S, Philipp T, Yoo J. Vitamin D deficiency during the perioperative period increases the rate of hardware failure and the need for revision fusion in adult patients undergoing single-level lumbar spine instrumentation surgery. NORTH AMERICAN SPINE SOCIETY JOURNAL 2023; 13:100197. [PMID: 36655115 PMCID: PMC9841266 DOI: 10.1016/j.xnsj.2022.100197] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Revised: 12/27/2022] [Accepted: 12/27/2022] [Indexed: 01/04/2023]
Abstract
Background Vitamin D has been shown to play important roles in both calcium homeostasis and bone healing. Only three studies have directly examined the relationship between vitamin D deficiency and hardware failure, nonunion, and/or revision surgery. Results are contradictory and none were large enough to provide the statistical power necessary to make definitive conclusions. Methods A retrospective analysis was performed utilizing the PearlDiver national insurance claims database consisting of 91 million individual patient records. Patients aged 30 and over who underwent a non-segmental posterior lumbar fusion procedure (CPT-22840) in 2012-2019 were included. Data collected included, hardware failure, revision surgery occurrence, and vitamin D deficiency. Hardware failure and revision rates were compared between vitamin D deficient and non-deficient groups. We ran a logistic regression analysis using the following variables: age, Charlson Comorbidity Index (CCI), gender, vitamin D deficiency, obesity, tobacco use, diabetes, osteoporosis, rheumatoid arthritis, and Crohn's disease. Results 108,137 patients matching inclusion criteria were identified, with an overall hardware failure rate of 2.7% and revision rate of 4.1%. Failure rates were significantly higher for patients diagnosed with vitamin D deficiency during the full queried period (3.3% vs. 2.6%, OR = 1.26; p < 0.0001), as were revision rates (4.3% vs 3.5%, OR = 1.25; p < 0.0001). Patients diagnosed with deficiency pre-surgery, higher failure (3.1% vs 2.6%, OR = 1.19; p < 0.01) and rates of revision (4.4% vs 3.5%, OR = 1.27; p < 0.0001) were increased compared to the non-deficient group. In the logistic regression analysis, vitamin D deficiency remains a significant contributor to hardware failure and revision surgery. Conclusions These results demonstrate that pre- and/or post-operative vitamin D deficiency is independently correlated with risk for hardware failure and revision surgery in single-level lumbar fusion patients.

Abstract
Coronaviruses have caused worldwide outbreaks in different periods. SARS (severe acute respiratory syndrome), was the first emerged virus from this family, followed by MERS (Middle East respiratory syndrome) and SARS-CoV-2 (2019-nCoV or COVID 19), which is newly emerged. Many studies have been conducted on the application of chemical and natural drugs for treating these coronaviruses and they are mostly focused on inhibiting the proteases of viruses or blocking their protein receptors through binding to amino acid residues. Among many substances which are introduced to have an inhibitory effect against coronaviruses through the mentioned pathways, natural components are of specific interest. Secondary and primary metabolites from plants, are considered as potential drugs to have an inhibitory effect on coronaviruses. IC50 value (the concentration in which there is 50% loss in enzyme activity), molecular docking score and binding energy are parameters to understand the ability of metabolites to inhibit the specific virus. In this study we did a review of 154 papers on the effect of plant metabolites on different coronaviruses and data of their IC50 values, molecular docking scores and inhibition percentages are collected in tables. Secondary plant metabolites such as polyphenol, alkaloids, terpenoids, organosulfur compounds, saponins and saikosaponins, lectins, essential oil, and nicotianamine, and primary metabolites such as vitamins are included in this study.

[PMID: 33739433 PMCID: PMC7980095 DOI: 10.1001/jamanetworkopen.2021.4117] [Citation(s) in RCA: 41] [Impact Index Per Article: 13.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Accepted: 02/10/2021] [Indexed: 12/18/2022] Open
Abstract
Importance Deficient (ie, <20 ng/mL) or insufficient (ie, 20 to <30 ng/mL) 25-hydroxyvitamin D (also known as calcifediol) levels are more common in Black individuals than White individuals and are associated with increased coronavirus disease 2019 (COVID-19) risk. Whether COVID-19 risk is associated with differences in vitamin D levels of 30 ng/mL or greater is not known. Objective To examine whether COVID-19 test results are associated with differences in vitamin D levels of 30 ng/mL or greater, including for White individuals and for Black individuals. Design, Setting, and Participants This retrospective cohort study was conducted at an academic medical center in Chicago, Illinois. Participants included individuals with data on vitamin D level within 365 days before COVID-19 testing, which was conducted from March 3 to December 30, 2020. Data were analyzed from September 11, 2020, to February 5, 2021. Exposures The last vitamin D level before COVID-19 testing was categorized as less than 20 ng/mL (ie, deficient), 20 to less than 30 ng/mL (ie, insufficient), 30 to less than 40 ng/mL, or 40 ng/mL or greater. Treatment was defined by vitamin D type and dose 14 days before COVID-19 testing and treatment changes after last vitamin D level. Main Outcomes and Measures The main outcome was a positive result for COVID-19 in polymerase chain reaction testing. Multivariable analyses tested whether previously measured vitamin D level was associated with having test results positive for COVID-19 in White individuals and in Black individuals, controlling for months and treatment changes since the vitamin D level was measured, as well as demographic characteristics and comorbidity indicators. Results A total of 4638 individuals (mean [SD] age 52.8 [19.5] years; 3205 [69%] women) had data for a vitamin D level within 1 year before COVID-19 testing, including 2288 (49%) Black individuals, 1999 (43%) White individuals, and 351 individuals (8%) who were another race/ethnicity (eg, Asian, Mideast Indian, >1 race). Stratified by vitamin D level, 1251 individuals (27%) had less than 20 ng/mL, 1267 individuals (27%) had 20 to less than 30 ng/mL, 1023 individuals (22%) had 30 to less than 40 ng/mL, and 1097 individuals (24%) had 40 ng/mL or greater. Lower vitamin D levels were more common in Black individuals (<20 ng/mL: 829 of 2288 Black individuals [36%]) than White individuals (<20 ng/mL: 315 of 1999 White individuals [16%]). A total of 333 individuals (7%) had test results positive for COVID-19, including 102 White individuals (5%) and 211 Black individuals (9%). Multivariate analysis controlling for time since last vitamin D level measurement was used to estimate the outcomes associated with levels 14 days before COVID-19 testing. A positive test result for COVID-19 was not significantly associated with vitamin D levels in White individuals but was associated with vitamin D levels in Black individuals (compared with ≥40 ng/mL: <20 ng/mL incidence rate ratio [IRR], 2.55 [95% CI, 1.26-5.15]; P = .009; 20 to <30 ng/mL IRR, 1.69 [95% CI, 0.75-3.84]; P = .21; 30 to <40 ng/mL IRR, 2.64 [95% CI, 1.24-5.66]; P = .01). Stratified by vitamin D level, estimated COVID-19 positivity rates in Black individuals were 9.72% (95% CI, 6.74%-13.41%) for individuals with a vitamin D level less than 20 ng/mL, 6.47% (95% CI, 3.33%-10.28%) for individuals with a vitamin D level of 20 to less than 30 ng/mL, 10.10% (95% CI, 6.00%-15.47%) for individuals with a vitamin D level of 30 to less than 40 ng/mL, and 3.82% (95% CI, 1.78%-6.68%) for individuals with a vitamin D level of 40 ng/mL or higher. Multivariate analysis in individuals with a vitamin D level of 30 ng/mL or greater found that the IRR of a positive COVID-19 test result was 0.97 (95% CI, 0.94-0.99; P = .008) per 1-ng/mL increase in vitamin D overall and 0.95 (95% CI, 0.91-0.98; P = .003) per 1-ng/mL increase in vitamin D in Black individuals. Conclusions and Relevance In this single-center retrospective cohort study, COVID-19 risk increased among Black individuals with vitamin D level less than 40 ng/mL compared with those with 40 ng/mL or greater and decreased with increasing levels among individuals with levels greater than 30 ng/mL. No significant associations were noted for White individuals. Randomized clinical trials should examine whether increasing vitamin D level to greater than 40 ng/mL affects COVID-19 risk.

Abstract
IMPORTANCE Vitamin D treatment has been found to decrease the incidence of viral respiratory tract infection, especially in patients with vitamin D deficiency. Whether vitamin D is associated with coronavirus disease 2019 (COVID-19) incidence is unknown. OBJECTIVE To examine whether the last vitamin D status before COVID-19 testing is associated with COVID-19 test results. DESIGN, SETTING, AND PARTICIPANTS This retrospective cohort study at an urban academic medical center included patients with a 25-hydroxycholecalciferol or 1,25-dihydroxycholecalciferol level measured within 1 year before being tested for COVID-19 from March 3 to April 10, 2020. EXPOSURES Vitamin D deficiency was defined by the last measurement of 25-hydroxycholecalciferol less than 20 ng/mL or 1,25-dihydroxycholecalciferol less than 18 pg/mL before COVID-19 testing. Treatment changes were defined by changes in vitamin D type and dose between the date of the last vitamin D level measurement and the date of COVID-19 testing. Vitamin D deficiency and treatment changes were combined to categorize the most recent vitamin D status before COVID-19 testing as likely deficient (last level deficient and treatment not increased), likely sufficient (last level not deficient and treatment not decreased), and 2 groups with uncertain deficiency (last level deficient and treatment increased, and last level not deficient and treatment decreased). MAIN OUTCOMES AND MEASURES The outcome was a positive COVID-19 polymerase chain reaction test result. Multivariable analysis tested whether vitamin D status before COVID-19 testing was associated with testing positive for COVID-19, controlling for demographic and comorbidity indicators. RESULTS A total of 489 patients (mean [SD] age, 49.2 [18.4] years; 366 [75%] women; and 331 [68%] race other than White) had a vitamin D level measured in the year before COVID-19 testing. Vitamin D status before COVID-19 testing was categorized as likely deficient for 124 participants (25%), likely sufficient for 287 (59%), and uncertain for 78 (16%). Overall, 71 participants (15%) tested positive for COVID-19. In multivariate analysis, testing positive for COVID-19 was associated with increasing age up to age 50 years (relative risk, 1.06; 95% CI, 1.01-1.09; P = .02); non-White race (relative risk, 2.54; 95% CI, 1.26-5.12; P = .009), and likely deficient vitamin D status (relative risk, 1.77; 95% CI, 1.12-2.81; P = .02) compared with likely sufficient vitamin D status. Predicted COVID-19 rates in the deficient group were 21.6% (95% CI, 14.0%-29.2%) vs 12.2%(95% CI, 8.9%-15.4%) in the sufficient group. CONCLUSIONS AND RELEVANCE In this single-center, retrospective cohort study, likely deficient vitamin D status was associated with increased COVID-19 risk, a finding that suggests that randomized trials may be needed to determine whether vitamin D affects COVID-19 risk.

Abstract
IMPORTANCE Vitamin D treatment has been found to decrease incidence of viral respiratory tract infection, especially in vitamin D deficiency. It is unknown whether COVID-19 incidence is associated with vitamin D deficiency and treatment. OBJECTIVE To examine whether vitamin D deficiency and treatment are associated with testing positive for COVID-19. DESIGN Retrospective cohort study Setting: University of Chicago Medicine Participants: Patients tested for COVID-19 from 3/3/2020-4/10/2020. Vitamin D deficiency was defined by the most recent 25-hydroxycholecalciferol <20ng/ml or 1,25-dihydroxycholecalciferol <18pg/ml within 1 year before COVID-19 testing. Treatment was defined by the most recent vitamin D type and dose, and treatment changes between the time of the most recent vitamin D level and time of COVID-19 testing. Vitamin D deficiency and treatment changes were combined to categorize vitamin D status at the time of COVID-19 testing as likely deficient(last-level-deficient/treatment-not-increased), likely sufficient(last-level-not-deficient/treatment-not-decreased), or uncertain deficiency(last-level-deficient/treatment-increased or last-level-not-deficient/treatment-decreased). MAIN OUTCOMES AND MEASURES The main outcome was testing positive for COVID-19. Multivariable analysis tested whether the most recent vitamin D level and treatment changes after that level were associated with testing positive for COVID-19 controlling for demographic and comorbidity indicators. Bivariate analyses of associations of treatment with vitamin D deficiency and COVID-19 were performed. RESULTS Among 4,314 patients tested for COVID-19, 499 had a vitamin D level in the year before testing. Vitamin D status at the time of COVID-19 testing was categorized as likely deficient for 127(25%) patients, likely sufficient for 291(58%) patients, and uncertain for 81(16%) patients. In multivariate analysis, testing positive for COVID-19 was associated with increasing age(RR(age<50)=1.05,p<0.021;RR(age≥50)=1.02,p<0.064)), non-white race(RR=2.54,p<0.01) and being likely vitamin D deficient (deficient/treatment-not-increased:RR=1.77,p<0.02) as compared to likely vitamin D sufficient(not-deficient/treatment-not-decreased), with predicted COVID-19 rates in the vitamin D deficient group of 21.6%(95%CI[14.0%-29.2%] ) versus 12.2%(95%CI[8.9%-15.4%]) in the vitamin D sufficient group. Vitamin D deficiency declined with increasing vitamin D dose, especially of vitamin D3. Vitamin D dose was not significantly associated with testing positive for COVID-19. CONCLUSIONS AND RELEVANCE Vitamin D deficiency that is not sufficiently treated is associated with COVID-19 risk. Testing and treatment for vitamin D deficiency to address COVID-19 warrant aggressive pursuit and study.

Abstract
It is an ugly fact that a significant amount of the world's population will contract SARS-CoV-II infection with the current spreading. While a specific treatment is not yet coming soon, individual risk assessment and management strategies are crucial. The individual preventive and protective measures drive the personal risk of getting the disease. Among the virus-contracted hosts, their different metabolic status, as determined by their diet, nutrition, age, sex, medical conditions, lifestyle, and environmental factors, govern the personal fate toward different clinical severity of COVID-19, from asymptomatic, mild, moderate, to death. The careful individual assessment for the possible dietary, nutritional, medical, lifestyle, and environmental risks, together with the proper relevant risk management strategies, is the sensible way to deal with the pandemic of SARS-CoV-II. A significant amount of the world's population will contract COVID-19 infection. Individual risk assessment and management strategies are crucial. Metabolic status determines the clinical severity of COVID-19, from asymptomatic to death. Important factors include diet, nutrition, age, sex, health, lifestyle, and environment.

Abstract
Ground-level falls (GLFs) are the number one cause of injury and death in the older adult population. We compared injury profiles of GLFs at SNFs to those at homes, hypothesizing that GLFs at SNFs would lead to higher risks for serious (AIS ≥ 3) traumatic brain injury (TBI) and lower extremity (LE) injuries compared to GLFs at home. The 2015-2016 Trauma Quality Improvement Program was used to compare patients sustaining GLFs at home and SNFs. From 15,873 patients sustaining GLFs, 14,306 (90.1%) occurred at home while 1,567 (9.9%) at SNFs. More patients with GLFs at SNFs were female, older, and had greater incidence of congestive heart failure, end-stage renal disease, and dementia ( p < 0.001) compared to those at home. Although, GLF SNF patients had lower injury severity scores (9 vs. 10, p < 0.001) and incidence for TBI (28.0% vs 33.4%, p < 0.001), they had a higher rate of femur fractures (55.1% vs. 38.9%, p < 0.001). After controlling for female, end stage renal disease, smoking, dementia, diabetes mellitus, chronic obstructive pulmonary disease, congestive heart failure, and stroke, patients falling at SNFs had an increased risk of sustaining serious LE injury AIS (OR 1.64, p < 0.001), but not serious TBI AIS (OR 0.89, p = 0.073). In conclusion, compared to GLFs at home, those at SNFs have a higher risk for serious LE injury, with femur fractures being the most common. However, GLFs at SNFs and homes had no significant difference in risk for serious TBI. Future studies are warranted to evaluate preventative measures to reduce LE injuries at SNFs.

The recent prevalence of osteoporosis and low bone mass in the United States based on bone mineral density at the femoral neck or lumbar spine. J Bone Miner Res 2014; 29:2520-6. [PMID: 24771492 PMCID: PMC4757905 DOI: 10.1002/jbmr.2269] [Citation(s) in RCA: 1129] [Impact Index Per Article: 112.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2014] [Revised: 04/06/2014] [Accepted: 04/09/2014] [Indexed: 12/12/2022]
Abstract
The goal of our study was to estimate the prevalence of osteoporosis and low bone mass based on bone mineral density (BMD) at the femoral neck and the lumbar spine in adults 50 years and older in the United States (US). We applied prevalence estimates of osteoporosis or low bone mass at the femoral neck or lumbar spine (adjusted by age, sex, and race/ethnicity to the 2010 Census) for the noninstitutionalized population aged 50 years and older from the National Health and Nutrition Examination Survey 2005-2010 to 2010 US Census population counts to determine the total number of older US residents with osteoporosis and low bone mass. There were more than 99 million adults aged 50 years and older in the US in 2010. Based on an overall 10.3% prevalence of osteoporosis, we estimated that in 2010, 10.2 million older adults had osteoporosis. The overall low bone mass prevalence was 43.9%, from which we estimated that 43.4 million older adults had low bone mass. We estimated that 7.7 million non-Hispanic white, 0.5 million non-Hispanic black, and 0.6 million Mexican American adults had osteoporosis, and another 33.8, 2.9, and 2.0 million had low bone mass, respectively. When combined, osteoporosis and low bone mass at the femoral neck or lumbar spine affected an estimated 53.6 million older US adults in 2010. Although most of the individuals with osteoporosis or low bone mass were non-Hispanic white women, a substantial number of men and women from other racial/ethnic groups also had osteoporotic BMD or low bone mass.

Abstract
BACKGROUND The prevalence of vitamin D insufficiency is very high in the nursing home (NH) population. Paradoxically, vitamin D insufficiency is rarely treated despite of strong clinical evidence and recommendations for supplementation. This review aims at reporting the current knowledge of vitamin D supplementation in NH and proposing recommendations adapted to the specificities of this institutional setting. DESIGN Current literature on vitamin D supplementation for NH residents was narratively presented and discussed by the French Group of Geriatrics and Nutrition. RESULT Vitamin D supplementation is a safe and well-tolerated treatment. Most residents in NH have vitamin D insufficiency, and would benefit from vitamin D supplement. However, only few residents are actually treated. Current specific and personalized protocols for vitamin D supplementation may not be practical for use in NH settings (e.g., assessment of serum vitamin D concentrations before and after supplementation). Therefore, our group proposes a model of intervention based on the systematic supplementation of vitamin D (1,000 IU/day) since the patient's admission to the NH and throughout his/her stay without the need of a preliminary evaluation of the baseline levels. Calcium should be prescribed only in case of poor dietary calcium intake. CONCLUSION A population-based rather than individual-based approach may probably improve the management of vitamin D insufficiency in the older population living in NH, without increasing the risks of adverse health problems. The clinical relevance and cost effectiveness of this proposal should be assessed under NH real-world conditions to establish its feasibility.

Abstract
The incidence of all-cause concussions in the United States is estimated to range from 1.6 to 3.8 million annually, with the reported number of sport- or recreation-related concussions increasing dramatically, especially in youth sports.(1,2) Additionally, the use of roadside bombs in Iraq and Afghanistan has propelled the incidence of concussion and other traumatic brain injuries to the highest levels ever encountered by the US military. As a result, there has also been a marked increase in postconcussion syndrome (PCS) and the associated cognitive, emotional, and memory disabilities associated with the condition. Unfortunately, however, there have been no significant advancements in the understanding or treatment of PCS for decades. The current management of PCS mainly consists of rest, reduction of sensory inputs, and treating symptoms as needed. Recently, researchers investigating the underlying mechanisms of PCS have proposed that activation of the immune inflammatory response may be an underlying pathophysiology that occurs in those who experience prolonged symptoms after a concussion. This article reviews the literature and summarizes the immune inflammatory response known as immunoexcitotoxicity. This article also discusses the use of nonpharmacological agents for the management of PCS that directly address this underlying mechanism.

Abstract
UNLABELLED We evaluated vertebral fracture prevalence using DXA-based vertebral fracture assessment and its influence on the Fracture Risk Assessment (FRAX) tool-determined 10-year fracture probability in a cohort of oldest old nursing home residents. More than one third of the subjects had prevalent vertebral fracture and 50% osteoporosis. Probably in relation with the prevailing influence of age and medical history of fracture, adding these information into FRAX did not markedly modify fracture probability. INTRODUCTION Oldest old nursing home residents are at very high risk of fracture. The prevalence of vertebral fracture in this specific population and its influence on fracture probability using the FRAX tool are not known. METHODS Using a mobile DXA osteodensitometer, we studied the prevalence of vertebral fracture, as assessed by vertebral fracture assessment program, of osteoporosis and of sarcopenia in 151 nursing home residents. Ten-year fracture probability was calculated using appropriately calibrated FRAX tool. RESULTS Vertebral fractures were detected in 36% of oldest old nursing home residents (mean age, 85.9 ± 0.6 years). The prevalence of osteoporosis and sarcopenia was 52% and 22%, respectively. Ten-year fracture probability as assessed by FRAX tool was 27% and 15% for major fracture and hip fracture, respectively. Adding BMD or VFA values did not significantly modify it. CONCLUSION In oldest old nursing home residents, osteoporosis and vertebral fracture were frequently detected. Ten-year fracture probability appeared to be mainly determined by age and clinical risk factors obtained by medical history, rather than by BMD or vertebral fracture.

Abstract
Background Numerous emerging data from research on osteoporosis among Asians found differences from Caucasians. Therefore, the aim of this study was to determine the prevalence of vitamin D insufficiency and osteoporosis in elderly participants from two nursing homes in Thailand, a country located near the equator. Methods The subjects of this cross-sectional study comprised 93 elderly Thai women who were living in institutional long-term nursing homes for the aged. Demographic data, daily food and calcium intake, physical activity, and sunlight exposure were measured. Lumbar spine and femoral neck bone mineral density (BMD) and biochemical levels including serum 25 hydroxyvitamin D [25(OH)D] and bone turnover markers were assessed. Vitamin D insufficiency was defined as 25(OH)D level < 70 nmol/l. Results The mean age of subjects was 75.2 ± 6.0 (SD) years. Dietary calcium intake was low (322 ± 158 mg/day) The mean 25(OH)D level was 64.3 ± 14.9 nmol/L and the prevalence of vitamin D insufficiency was 38.7% (95% CI: 28.8%, 49.4%). There was no correlation between serum 25(OH)D concentrations and age (r = −.11, p = 0.3). The mean BMD of lumbar spine and femoral neck were 0.92 ± 0.19 and 0.65 ± 0.10 g/cm2, respectively. Nearly a half of the subjects had osteopenia (44.1%, 95% CI: 33.8%, 54.8%) and osteoporosis (47.3%, 95% CI: 36.9%, 57.9%). Circulating C-terminal telopeptide of type I collagen (CTx) level correlated significantly with both lumbar spine (r = −0.26, p = 0.01) and femoral neck BMD (r = −0.25, p = 0.02). Conclusions More than one-third of Thai elderly women residing in nursing homes had vitamin D insufficiency. Almost all nursing home residents had osteoporosis and/or osteopenia.

Abstract
SUMMARY Bisphosphonate treatment rates were examined before and after admission to long-term residential care. Bisphosphonate treatment rates were low (16%) pre-admission but doubled after long-term residential care admission (30%). Men were very undertreated for osteoporosis, while a history of falls with injury was not associated with treatment. INTRODUCTION To determine the rates and independent correlates of bisphosphonate treatment in elderly residents before and after admission to long-term care (LTC) institutions. METHODS Information was collected from records of 421 residents of four LTC institutions in Edmonton, Alberta, Canada. Osteoporosis-related diagnoses, treatments, and risk factors including falls in LTC and any adulthood fractures were abstracted. Osteoporosis was defined by physician diagnosis or documented fractures of the hip, spine, or upper extremity. Multivariable analyses were undertaken to determine factors independently associated with bisphosphonate treatment. RESULTS Mean age was 84 ± 8 years and 290 (70%) were female. Overall, 142 (34%) had previous fractures, 170 (41%) had physician-diagnosed osteoporosis, and 227 (54%) residents met the study's clinical definition of osteoporosis. Of those with osteoporosis, 44 (19%) were men. Before admission, 36 (16%) patients with osteoporosis were treated with bisphosphonates; after admission another 31 (14%) were started on bisphosphonates by LTC physicians. Women were far more likely than men to start bisphosphonate treatment [30 (97%) women vs. 1 (3%) man, adjusted odds ratio (aOR) = 9.20 (95% confidence intervals 1.2,70.5)]. Falls with injury were common [72/227 (31%)] but not associated with bisphosphonate treatment (adjusted p value > 0.5). CONCLUSION Rates of pre-admission bisphosphonate treatment were low, but did double after LTC admission. Women were almost ten times more likely to start bisphosphonate treatment than men, although one fifth of those with documented osteoporosis were men. Although falls cause most fractures, a history of falls with injury was not associated with bisphosphonate treatment. Our findings suggest that targeting men and residents with falls for treatment with bisphosphonates might be warranted.

Abstract
Recent studies suggest that vitamin D modulates innate immunity and reduces the risk of microbial infections. Little is known about the role of vitamin D in antipneumococcal immunity in individuals with asthma. We determined the correlation between serum 25-hydroxyvitamin D (25[OH]D) levels and pneumococcal antibody levels in individuals with asthma, atopic dermatitis, or allergic rhinitis, and atopic sensitization status. A cross-sectional study was conducted for 21 subjects with asthma and 23 subjects without asthma. Pearson's correlation coefficient between serum 25(OH)D concentrations and the number of positive serotype-specific antibody levels was calculated among individuals with and without asthma, atopic dermatitis, and/or allergic rhinitis and atopic sensitization status. The overall correlation between serum 25(OH)D concentrations and positive pneumococcal antibody levels in all subjects regardless of asthma was not significant (r = -0.14; p = 0.38). Stratified analysis results showed that there was a positive correlation between serum 25(OH)D concentrations and positive pneumococcal antibody levels in asthmatic patients (r = 0.45; p < 0.05) and an inverse correlation was observed in nonasthmatic patients (r = -0.53; p < 0.05). These trends were similar for subjects with and without atopic dermatitis and/or allergic rhinitis (r = 0.58 and p = 0.008 versus r = -0.63 and p = 0.001). Despite similar trends in the correlation between serum 25(OH)D and pneumococcal antibody concentrations among those with and without atopic sensitization status (r = 0.27 and p = 0.19 versus r = -0.41 and p = 0.08), they did not reach statistical significance. The 25(OH)D may enhance humoral immunity against Streptococcus pneumonia in subjects with atopic conditions but not without atopic conditions. Atopic conditions may have an important effect modifier in the relationship between serum 25(OH)D concentrations and immune function.

Abstract
Problem solving using a collaborative approach may reduce the risk of falls in the nursing home. Interventions need to be tailored to the individual's cognitive and physical impairments as well as be feasible in the particular long-term care setting. Polypharmacy, Vitamin D deficiency, delirium, and urinary incontinence are among several risks for falls that are discussed in this article.

Abstract
The older senior is at high risk for osteoporosis. It is important for healthcare providers to be fully aware of the potential risks and benefits of diagnosing and treating osteoporosis in the older senior population. Data indicate that bone mineral density testing is under-utilized and drug therapy is often not initiated when indicated in this population. Bone mineral density testing with central dual energy x-ray absorptiometry is essential and cost-effective in this population. All older seniors should be educated on a bone-healthy lifestyle including age-appropriate weight-bearing exercise and smoking cessation if necessary. It is important to remember that falls play a very important role in the risk for osteoporotic fractures, especially in the older senior. All older seniors should be evaluated annually for falls and strategies should be implemented to reduce fall risk in this population. The risk for vitamin D insufficiency and deficiency is high in the older senior and can contribute to falls and fractures. Adequate intakes of calcium and vitamin D are important and deficiencies need to be treated. Data on osteoporosis drug therapy in the older senior are lacking. Based on data from subgroup analyses of large osteoporosis trials in postmenopausal women, current osteoporosis therapies appear safe and efficacious in the older senior and most will live long enough to derive a benefit from these therapies. Further studies are needed in older seniors, especially men, to better understand the risks and benefits of pharmacologic therapy for the management of osteoporosis.

Abstract
UNLABELLED This prospective study finds that ergocalciferol 50,000 IU three times weekly for four weeks effectively and safely corrects vitamin D inadequacy in nursing home residents. INTRODUCTION Low vitamin D status is common among nursing home residents and contributes to bone loss, falls and fractures. The objective of this study was to evaluate the efficacy and safety of short course, high dose, oral vitamin D(2) (ergocalciferol) treatment. METHODS This prospective study included 63 nursing home residents. The 25 with low vitamin D status (serum 25(OH)D < or = 25 ng/ml) received oral ergocalciferol 50,000 IU three times weekly for four weeks; the others received no change to their routine care. Serum total 25(OH)D, 25(OH)D(2), 25(OH)D(3), calcium, parathyroid hormone (PTH), bone turnover markers and neuro-cognitive assessments were obtained at baseline and four weeks. RESULTS Mean total 25(OH)D concentration increased (p < 0.0001) from 17.3 to 63.8 ng/ml in the treated group and remained unchanged in the comparison group. Serum 25(OH)D(3) remained stable in the comparison group, but declined (p < 0.0001) with D(2) treatment from 15.4 to 9.1 ng/ml. Serum PTH trended down in the treatment group (p = 0.06). No treatment-induced improvement in ambulation, cognition or behavior was observed. No hypercalcemia or other adverse effects were observed with ergocalciferol treatment. CONCLUSION Four weeks of oral vitamin D(2) supplementation effectively and safely normalizes serum 25(OH)D in nursing home residents.

Abstract
OBJECTIVE To identify women 60 years of age or older at risk for osteoporosis, provide education, and refer at-risk women to physicians through a community pharmacy screening program and to develop a model in community pharmacies for this service. DESIGN Cross-sectional study. SETTING Northwest Iowa between August 2005 and October 2005. PARTICIPANTS 159 women 60 years of age or older screened at five pharmacies. INTERVENTIONS Five pharmacies completed education on osteoporosis, received training on use of the Achilles InSight by GE Lunar, and screened women 60 years of age or older for osteoporosis. Patients received education on osteoporosis and risk factors during the screening and were stratified as low, moderate, or high risk based on a T-score. Patients at risk were referred to their physician for further evaluation. Pharmacists telephoned patients at 3 and 6 months after screening to determine self-initiated or provider-initiated changes in their treatment plan. MAIN OUTCOME MEASURES Descriptive population characteristics, proportion of participants with medical risk factors for osteoporosis, proportion of patients screened at risk, and proportion of physician or patient self-initiated changes instituted as a result of the screening. RESULTS Of the 159 women screened, 53% were rated as moderate or severe risk and referred to their physicians. Three- and 6-month follow-up results revealed a high proportion of self-initiated lifestyle or medication changes and a small proportion of physician-initiated changes. CONCLUSION The majority of women 60 years of age or older who attended a community pharmacy osteoporosis screening were at moderate or high risk for osteoporosis. A fee-for-service model was created for community pharmacists to improve recognition and treatment of patients at risk. A toolkit will be created for pharmacists to promote their role in improving the bone health of older patients.

Abstract
BACKGROUND Vitamin D deficiency is common in older populations, particularly during the winter months due to low levels of ultraviolet light exposure, and in nursing home residents. OBJECTIVE The main objective of the current study was to assess the distribution of serum 25-hydroxyvitamin D and its correlates in a sample of men and women with recent hip fractures who were part of a large clinical trial. METHODS This was a cross-sectional exploratory study of screened and ultimately randomized patients with hip fractures. They were part of a multinational (115 clinical centers in 20 countries), randomized, placebo-controlled, double-blind study testing the efficacy of a yearly IV bisphosphonate (zoledronic acid) in the prevention of new clinical fractures in patients with recent hip fracture repair. Levels of 25-hydroxyvitamin D, calcium, alkaline phosphatase, creatinine clearance, and albumin were measured at a screening visit using blood serum. Demographic variables were assessed by patient self-report. Bone mineral density (BMD) was assessed by dual-energy x-ray absorptiometry of the nonfractured hip. RESULTS This report included 1174 screened patients (526 with vitamin D measured) and 655 (385 with vitamin D measured) patients randomized before the protocol amendment. In screened patients, levels of 25-hydroxyvitamin D were low (median, 14.7 ng/mL; interquartilc range, 7.6, 21.65). Overall, 51% were at or below the clinically meaningful threshold of 15 ng/mL. Among those patients randomized, the level of 25-hydroxyvitamin D was significantly positively related to male sex (rho, 0.13; P < 0.05), serum calcium (rho, 0.16; P < 0.01), and BMD at the femoral neck (rho, 0.22; P < 0.01) in bivariate analyses. Low serum 25-hydroxyvitamin D (<15 ng/mL) was related only to low serum calcium (odds ratio, 0.16; 95% CI, 0.05-0.52) in multivariable logistic models controlling for sex, age, race, body mass index, living at home, alkaline phosphatase, and creatinine clearance. CONCLUSIONS We concluded that vitamin D insufficiency was a common problem in this population of elderly patients who had recently suffered a hip fracture. This insufficiency was related only to serum calcium in multivariable controlled models but cannot be reliably identified or excluded by measuring serum calcium alone. Physicians should be encouraged to check and monitor patients' serum levels of 25-hydroxyvitamin D.

Abstract
Vitamin D insufficiency is common in the United States; the elderly and African-Americans are at particularly high risk of deficiency. This review, written for a broad scientific readership, presents a critical overview of scientific evidence relevant to a possible causal relationship between vitamin D deficiency and adverse cognitive or behavioral effects. Topics discussed are 1) biological functions of vitamin D relevant to cognition and behavior; 2) studies in humans and rodents that directly examine effects of vitamin D inadequacy on cognition or behavior; and 3) immunomodulatory activity of vitamin D relative to the proinflammatory cytokine theory of cognitive/behavioral dysfunction. We conclude there is ample biological evidence to suggest an important role for vitamin D in brain development and function. However, direct effects of vitamin D inadequacy on cognition/behavior in human or rodent systems appear to be subtle, and in our opinion, the current experimental evidence base does not yet fully satisfy causal criteria. Possible explanations for the apparent inconsistency between results of biological and cognitive/behavioral experiments, as well as suggested areas for further research are discussed. Despite residual uncertainty, recommendations for vitamin D supplementation of at-risk groups, including nursing infants, the elderly, and African-Americans appear warranted to ensure adequacy.

Abstract
SUMMARY We studied nursing home residents with osteoporosis or recent fracture to determine the frequency and predictors of osteoporosis treatment. There was wide variation in performance, and both clinical and systems variables predicted use. This study shows that improvement in osteoporosis care is possible and important for many nursing homes. INTRODUCTION We determined the prevalence and predictors of osteoporosis evaluation and treatment in high-risk nursing home residents. METHODS We identified 67 nursing facilities in North Carolina and Arizona with > 10 residents with osteoporosis or recent hip fracture. Medical records (n=895) were abstracted for osteoporosis evaluation [dual-energy X-ray absorptiometry (DXA), vitamin D level, serum calcium), treatment (calcium, vitamin D, osteoporosis medication, hip protectors), clinical, and systems covariates. Data were analyzed at the facility level using mixed models to account for the complex nesting of residents within providers and nursing facilities. RESULTS Calcium and vitamin D was prescribed for 69% of residents, bisphosphonates for 19%, calcitonin for 14%, other pharmacologic therapies for 6%, and hip protectors for 2%. Overall, 36% received any bone protection (medication or hip protectors), with wide variation among facilities (0-85%). Factors significantly associated with any bone protection included female gender [odds ratio (OR) 2.4, (1.5-3.7)] and nonurban/suburban location [1.5, (1.1-2.2)]. Residents with esophagitis, peptic ulcer disease (PUD), or dysphagia [0.6, (0.4-0.9)] and alcohol abuse [0.2, (0.0-0.9)] were less likely to receive treatment. CONCLUSIONS There is substantial variation in the quality of osteoporosis treatment across nursing homes. Interventions that improve osteoporosis quality of care are needed.

Abstract
OBJECTIVES Patients in long-term care institutions (LTCI) are especially at risk for osteoporotic fractures owing to their lack of mobility, poor nutrition, and limited sun exposure. Previous reports have shown that osteoporosis is underdiagnosed and undertreated in LTCI despite the high incidence of osteoporotic fractures in these settings. This document has been developed to assist clinicians practicing in LTCI with the diagnosis and treatment of osteoporosis in their institutionalized patients. These proceedings offer an overview of the particular characteristics of patients at LTCI. Management strategies include both nonpharmacological and pharmacological interventions for the prevention and treatment of osteoporotic fractures in very frail older subjects. PARTICIPANTS This guide is an edited review of presentations and discussions held by specialists in osteoporosis in the elderly together with physicians and pharmacists practicing in LTCI in the province of Quebec. This symposium was held in Saint-Hyacinthe, Quebec on November 5, 2004. VALUES The value of a given diagnostic test or treatment option was determined based on the clinical experiences and opinions of the participants and a review of the literature from an evidence-based perspective. RECOMMENDATIONS All patients located at LTCI are at potential risk for osteoporotic fractures. Global interventions should include vitamin D, calcium, and a comprehensive exercise program. In patients who are at high risk for osteoporotic fractures or with previous fractures, pharmacological treatment should be started. VALIDATION These recommendations were approved during the final plenary of the symposium. All the prevailing opinions were summarized and included in this article.

Abstract
INTRODUCTION There are very few published studies on osteoporosis among the institutionalized elderly in Asian countries, where the incidence of osteoporosis is increasing rapidly. Our objectives were to determine both the prevalence and risk factors of osteoporosis, as assessed by calcaneal bone mineral density (BMD) measurements, in a Thai nursing home. METHODS Activities of daily living, the Mini-Mental State Examination, blood chemistry, body composition analysis, calcaneal quantitative ultrasound (QUS) and serum C-terminal telopeptides of type I collagen (serum beta-CTx) were assessed in 108 older people living in the largest nursing home for the elderly in Bangkok. Calcaneal BMD was measured by dual-energy X-ray absorptiometry (DXA). RESULTS The prevalence of osteoporosis, as defined by a calcaneal BMD T-score <1.6, was 79.6%. The prevalence of low bone mass, as defined by a T-score of broadband ultrasound attenuation <1.0, was 80.6%. The prevalence of osteoporosis detected by these two methods was not significantly different (p=1.00). The prevalence of increased bone turnover [with the cutoff point being the mean + 2 standard deviation (SD) of the serum beta-CTx level of a sex- and age-matched control group] was 13.9%. In multiple linear regression analysis, five risk factors -- serum beta-CTx, mental health, mobility index, height and lean body mass -- were able to predict calcaneal BMD at a coefficient of determination R(2)) of 0.54. CONCLUSIONS These results indicate the importance of mental health and self-care ability as factors associated with osteoporosis. Increased bone turnover was also a significant risk factor of low bone mass. Calcaneal QUS was a useful screening tool for diagnosing osteoporosis in this population and was comparable to calcaneal DXA.

Abstract
BACKGROUND Vitamin D inadequacy has been studied extensively, due to concerns about ageing populations, associations with osteoporosis and other disorders (including non-musculoskeletal), and high prevalence. AIM To review recent reports on the prevalence of vitamin D inadequacy among post-menopausal women with and without osteoporosis and/or other musculoskeletal diseases. DESIGN Systematic review. METHODS We reviewed publications in the past 10 years reporting prevalence estimates for vitamin D inadequacy, reported as serum 25(OH)D values below various levels. Thirty published studies in the English language were identified, from January 1994 through April 2004. RESULTS In osteoporotic populations, the prevalence of 25(OH) vitamin D concentration <12 ng/ml ranged from 12.5% to 76%, while prevalence rates reached 50% to 70% of patients with a history of fracture(s) using a cut-off of 15 ng/ml. In post-menopausal women, the prevalence of 25(OH) vitamin D concentrations <or=20 ng/ml ranged from 1.6% to 86% for community-living and institutionalized women, respectively. The most common factors associated with inadequate vitamin D levels included limited sun exposure, lack of dietary vitamin D intake, nursing home environment, wintertime, and increasing age (over 70 years). DISCUSSION The prevalence of inadequate vitamin D levels appears to be high in post-menopausal women, especially in those with osteoporosis and history of fracture. Vitamin D supplementation in this group might offer scope for prevention of falls and fracture, especially in elderly and osteoporotic populations.
