[PMID: 34807010 PMCID: PMC9007206 DOI: 10.1097/corr.0000000000002051] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2021] [Accepted: 10/25/2021] [Indexed: 01/31/2023]
Abstract
BACKGROUND Previous studies on medical costs in patients with hip fractures have focused on medical costs incurred for a short period after the injury. However, patients often had comorbidities before their hip fractures that would have affected medical costs even had they not sustained a fracture. Consequently, these studies may have overestimated the costs associated with hip fractures and did not characterize the duration of increased medical costs adequately. Without knowing this crucial information, it is difficult to craft thoughtful health policy to support these patients' needs. QUESTIONS/PURPOSES (1) To compare the direct medical costs for 5 years before fracture and up to 5 years after injury in a group of patients who underwent hip fracture surgery with a matched group of patients who did not experience a hip fracture, (2) to analyze the duration over which the increased direct medical costs associated with a hip fracture continues, and (3) to analyze whether there is a difference in direct medical costs according to age group using a nationwide claims database in South Korea. METHODS The National Health Insurance Service Sample cohort in South Korea consisted of 1 million patients who were selected using a systematic, stratified, random sampling method from 48,222,537 individuals on December 31, 2006. Under a compulsory social insurance system established by the National Health Insurance Act, all patients were followed until 2015. Patients with hip fractures and matched controls were selected from the National Health Insurance Service sample of South Korea. Patients with hip fractures were defined as those who were hospitalized with a diagnosis of femoral neck fracture or intertrochanteric fracture and who underwent surgical treatment. We excluded patients with hip fractures before January 1, 2007 to ensure a minimum 5-year period that was free of hip fractures. Patients with hip fractures were matched with patients of the same age and gender at the date of admission to an acute care hospital for surgery (time zero). If patients with hip fractures died during the follow-up period, we performed matching among patients whose difference from the time of death was within 1 month. This method of risk-set matching was repeated sequentially for the next patient until the last patient with a hip fracture was matched. We then sequentially performed 1:5 random sampling for each risk set. A total of 3583 patients in the hip fracture cohort (patients with hip fractures) and 17,915 patients in the matched cohort (those without hip fractures) were included in this study. The mean age was 76 ± 9 years, and 70% were women in both groups. Based on the Charlson comorbidity index score, medication, and medical history, the patients with hip fractures had more comorbidities. Person-level direct medical costs per quarter were calculated for 5 years before time zero and up to 5 years after time zero. Direct medical costs were defined as the sum of that insurer's payments (that is, the National Health Insurance Service's payments), and that patient's copayments, excluding uncovered payments. We compared direct medical costs between patients with hip fractures and the patients in the matched cohort using a comparative interrupted time series analysis. The difference-in-difference estimate is the ratio of the differences in direct medical costs before and after time zero in the hip fracture cohort to the difference in direct medical costs before and after time zero in the matched cohort; the difference in difference estimates were calculated each year after injury. To identify changes in direct medical cost trends in patients with hip fractures and all subgroups, joinpoint regression was estimated using statistical software. RESULTS The direct medical costs for the patients with hip fractures were higher than those for patients in the matched cohort at every year during the observation period. The difference in direct medical costs between the groups before time zero has increased every year. The direct medical costs in patients with hip fractures was the highest in the first quarter after time zero. Considering the differential changes in direct medical costs before and after time zero, hip fractures incurred additional direct medical costs of USD 2514 (95% CI 2423 to 2606; p < 0.01) per patient and USD 264 (95% CI 166 to 361; p < 0.01) per patient in the first and second years, respectively. The increase in direct medical costs attributable to hip fracture was observed for 1.5 to 2 years (difference-in-difference estimate at 1 year 3.0 [95% CI 2.8 to 3.2]; p < 0.01) (difference-in-difference estimate at 2 years 1.2 [95% CI 1.1 to 1.3]; p < 0.01; joinpoint 1.5 year). In the subgroups of patients younger than 65, patients between 65 and 85, and patients older than 85 years of age, the increase in direct medical costs attributable to hip fracture continued up to 1 year (difference-in-difference estimate ratio at 1 year 2.7 [95% CI 2.1 to 3.4]; p < 0.01; joinpoint 1 year), 1.5 to 2 years (difference-in-difference estimate ratio at 1 year 2.8 [95% CI 2.6 to 3.1]; p < 0.01; difference-in-difference estimate ratio at 2 years 1.2 [95% CI 1.1 to 1.3]; p < 0.01; joinpoint 1.5 years), and 39 months to 5 years (difference-in-difference estimate ratio at 1 year 5.2 [95% CI 4.4 to 6.2]; p < 0.01; difference-in-difference estimate ratio at 5 years 2.1 [95% CI 1.4 to 3.1]; p < 0.01; joinpoint 39 months) from time zero, respectively. CONCLUSION The direct medical costs in patients with hip fractures were higher than those in the matched cohort every year during the 5 years before and after hip fracture. The increase in direct medical costs because of hip fractures was maintained for 1.5 to 2 years and was greater in older patients. Based on this, we suggest that health policies should focus on patients' financial and social needs, with particular emphasis on the first 2 years after hip fracture with stratification based on patients' ages.

Abstract
The bone health status of a Mexican female population, including a cohort of 455 women aged over 40 years, was assessed by Radiofrequency Echographic Multi Spectrometry (REMS). PURPOSE Assessment of the bone health status in an average female Mexican population with REMS. The secondary objective investigated age- and body mass index (BMI)-related effects on the diagnostic classification and the influence of risk factors for osteoporosis. METHODS Women aged over 40 years underwent a REMS scan at the lumbar spine and both femoral necks. The degree of correlation of the bone mineral density (BMD) across axial sites was assessed by the Pearson correlation coefficient (r), along with the diagnostic discordance. The association between risk factors, age, and BMI and diagnostic classification was determined by the chi-squared test. RESULTS Four hundred seventy-one women were enrolled. Osteoporosis was diagnosed in 11.0%, 8.1%, and 8.3% of cases at the lumbar spine and right and left femoral neck, respectively. The diagnostic agreement between the lumbar spine and femoral necks was about 73% (85% considering a 0.3 T-score tolerance), whereas the agreement between the femoral necks was 97.4% (99.6% considering a 0.3 T-score tolerance). Most of discordant cases were minor discordances. The correlation between the lumbar spine and femoral neck was r = 0.82 and 0.85, respectively, whereas both femoral necks correlated with r = 0.97. As expected, the prevalence of osteoporosis increased with age and decreased as BMI increased. CONCLUSION The widespread applicability of the non-ionizing REMS technology has been demonstrated in a representative Mexican cohort, covering wide age and BMI ranges. Age and BMI variations correlate with the prevalence of osteoporosis, in line with the recent scientific literature.

Abstract
Background: Osteoporosis is a skeletal disease that is associated with a reduction in bone mass and microstructures and deterioration of bone tissue. It is also associated with an increased risk of fracture that is the most important complication of osteoporosis. The knowledge about costs and economic aspects of osteoporosis plays an important role in making policies and planning measures for the prevention and management of this disease; hence, this study systematically investigated the available evidence on the costs associated with osteoporosis worldwide. Methods: In this systematic review, electronic searches were performed on various online databases, including PubMed, Embase, Scopus, web of science, ProQuest, and Cochrane. The timeframe selected for searching articles was from 1980 to 2018. Results: Of a total of 1989 papers, 28 papers were included in the study on the basis of inclusion criteria. Based on the data extracted from the mentioned studies, the mean age of people with osteoporotic fractures was 50 years, with the highest costs associated with hip fractures. Conclusion: Our review indicated that the cost of osteoporosis carries a significant economic burden on countries in the world. The main cost drivers in this study were Fracture-related costs. The direct annual cost of treating osteoporotic fractures of people on average is reported to be between 5000 and 6500 billion USD in Canada, Europe and the USA alone, not taking into account indirect costs such as disability and loss of productivity. Prevention of this disease can significantly reduce the costs incurred by the health system.

Abstract
Incidence rates of hip fractures in Latin America continue to rise. These fractures are associated with factors such as health, education, and socioeconomic status. Although there are many well-developed public and private healthcare systems available, the quality and consistency in the management of patients with hip fractures varies substantially. This article provides a summary review of national hip fracture care guidelines in 4 of the largest countries in Latin America (Mexico, Colombia, Brazil, and Argentina), describing national guidelines, audits, standard treatment approaches in each country and regional policies; with the goal of understanding and comparing the different guidelines, identifying the main problems in each country, learning from the policies of the other countries, and developing improvement projects.

Abstract
Objective: Osteoporosis is under-diagnosed and under-treated worldwide. Information on the burden of osteoporosis in Latin American countries is limited. This study aimed to estimate the economic burden of osteoporosis in adults aged 50-89 years in Brazil, Mexico, Colombia, and Argentina. Methods: Analyses were conducted using a burden of illness model. Where possible, country-specific model inputs were informed by a systematic review and expert opinion. Osteoporosis-related fracture costs were calculated for hospitalizations, testing, surgeries, prescription drugs, and patient productivity losses. Costs were expressed in 2018 USD for the annual burden, annual burden per 1,000 at risk, and projected 5-year burden. No discounting was applied. Results: Over 840,000 osteoporosis-related fractures were predicted to occur in 2018, amounting to a total annual cost of ∼1.17 billion USD. The total projected 5-year cost was ∼6.25 billion USD. Annual costs were highest in Mexico (411 million USD), followed by Argentina (360 million USD), Brazil (310 million USD), and Colombia (94 million USD). The average burden per 1,000 at risk was greatest in Argentina (32,583 USD), followed by Mexico (16,671 USD), Colombia (8,240 USD), and Brazil (6,130 USD). Conclusions: Over the next 5 years, ∼4,485,352 fractures are anticipated to occur in Brazil, Mexico, Colombia, and Argentina. To control and prevent these fractures, stakeholders must work together to close the care gap. Efforts to identify individuals at high fracture risk, initiate treatment, and improve long-term treatment persistence will be essential in minimizing the financial and patient burden of osteoporosis in Latin America.

Abstract
The purpose of this study was to estimate the current economic burden of osteoporosis in South Korea using national claim data of the Korean National Health Insurance Service (KNHIS) from 2008 to 2011. Patients aged 50 years or older were identified from KNHIS nationwide database for all records of outpatient visits or hospital admissions. Healthcare costs for osteoporotic patients included direct medical costs for hospitalization, outpatient care, and prescription drugs for the year after discharge. Healthcare costs were estimated based on the perspective of KNHIS, and calculated using a bottom-up approach. Between 2008 and 2011, total healthcare costs for osteoporotic patients increased from 3976 million USD to 5126 million USD, with an annual increase of 9.2% which accounted for one-sixth (16.7%) of national healthcare expenditure. Healthcare cost for hospitalization was the highest ($1903 million, 40.0% of total healthcare cost), followed by cost for outpatient care ($1474 million, 31.0%) and cost for prescription drugs ($1379 million, 29.0%). Although total healthcare cost for osteoporotic men was 6 times lower than that for osteoporotic women, the cost per person was 1.5 times higher than that for women. Total healthcare cost for osteoporotic patients without fractures was higher than that for osteoporotic patients with fractures. However, cost per person was the opposite. Osteoporosis entails substantial epidemiologic and economic burden in South Korea. This study provides information about the total healthcare burden, which could be important when determining what attention and awareness osteoporosis should be given in the public health system.

Abstract
Background The present study estimated healthcare costs of osteoporotic fractures including spine, hip, distal radius and humerus in Koreans over 50 years of age using national claims data. Methods Korea National Health Insurance data between 2008 and 2011 was searched for all claims records of outpatient visits or hospital admissions of patients ≥50-year-of-age. Osteoporosis-related fractures were identified using certain the International Classification of Diseases, Tenth Revision codes and site-specific physician claims for procedures in a patient age cut-off value of 50 years. The healthcare costs included acute phase costs accounting for emergency medical care given immediately after fracture, costs due to further hospitalization and surgical procedures, physiotherapy sessions according to the site of the fracture, and outpatient visits in the year after discharge. Results The total estimated healthcare costs of osteoporotic fractures in 2011 was $722 million. From 2008 to 2011, the total number and healthcare costs of osteoporotic fractures increased 28.9% (from 127,070 to 163,823) and 31.6% (from $549 million to $722 million), respectively. The portion of national health care expenditure was ranged from 2.3% in 2008 to 2.2% in 2011. The mean healthcare cost of osteoporotic fractures per person increased 2.1% from $4,321 in 2008 to $4,410 in 2011.The mean healthcare costs were highest for hip fractures followed by spine, humerus, and distal radius fractures. Conclusions Total Healthcare costs of osteoporotic fractures in South Koreans ≥50-year-of-age increased between 2008 and 2011. This trend will likely continue, which is an important health problem in the elderly population and economically.

Abstract
Introduction The increasing burden of dengue fever (DF) in the Americas, and the current epidemic in previously unaffected countries, generate major costs for national healthcare systems. There is a need to quantify the average cost per DF case. In Mexico, few data are available on costs, despite DF being endemic in some areas. Extrapolations from studies in other countries may prove unreliable and are complicated by the two main Mexican healthcare systems (the Secretariat of Health [SS] and the Mexican Social Security Institute [IMSS]). The present study aimed to generate specific average DF cost-per-case data for Mexico using a micro-costing approach. Methods Expected medical costs associated with an ideal management protocol for DF (denoted ´ideal costs´) were compared with the medical costs of current treatment practice (denoted ´real costs´) in 2012. Real cost data were derived from chart review of DF cases and interviews with patients and key personnel from 64 selected hospitals and ambulatory care units in 16 states for IMSS and SS. In both institutions, ideal and real costs were estimated using the program, actions, activities, tasks, inputs (PAATI) approach, a micro-costing technique developed by us. Results Clinical pathways were obtained for 1,168 patients following review of 1,293 charts. Ideal and real costs for SS patients were US$165.72 and US$32.60, respectively, in the outpatient setting, and US$587.77 and US$490.93, respectively, in the hospital setting. For IMSS patients, ideal and real costs were US$337.50 and US$92.03, respectively, in the outpatient setting, and US$2,042.54 and US$1,644.69 in the hospital setting. Conclusions The markedly higher ideal versus real costs may indicate deficiencies in the actual care of patients with DF. It may be necessary to derive better estimates with micro-costing techniques and compare the ideal protocol with current practice when calculating these costs, as patients do not always receive optimal care. Dengue fever (DF) is caused by infection with the dengue virus, which is spread by the Aedes aegypti mosquito. Although the effects of DF are usually mild, in some cases serious illness and even death may result. The average costs per case when extrapolated to society may therefore be high, particularly given the large number of people infected during an endemic year. In Mexico, relatively little is known about the average cost per case (from either the healthcare system or the patient perspective). Such information is important to guide decisions about health policy, e.g. vaccination or public education. We aimed to quantify the average cost per case of DF using a micro-costing approach, both for DF treatment according to an ideal protocol for the management of the patient (´ideal costs´) and according to current treatment practice in the health services (´real costs´). Our results were largely consistent with findings from other international studies, but showed higher ideal costs compared with real costs. We think this may point to inadequate use of laboratory tests and treatments for patients with DF in Mexico. Our cost data will be used in a subsequent publication regarding the economic impact of DF in Mexico.

Abstract
Osteoporotic femoral neck fractures are increasing as the population ages. There is a significant cost to care for patients with such fractures. We prospectively analysed the in-hospital cost of managing 85 patients admitted to the University Hospital of the West Indies (UHWI) with such fractures. The majority of patients were females, 78.8%, and the mean age of the cohort was 83.7 years. There was a significant difference in the mean preoperative delay and length of stay between those patients treated publicly as compared to those treated privately, 9.6 vs 3.1 days and 18.9 vs 8.8 days, respectively. The mean acute cost of those treated publicly was 39% of the cost of those treated privately, J$110 878.80 vs J$284 287.61. The economic cost per year to the country for the acute management of femoral neck fractures was calculated at J$46 264 528.76 which is 0.30% of the 2005-2006 budgetary allocation for health. This cost was significantly associated with the length of hospital stay and the number of complications developed.

Abstract
BACKGROUND Hip fracture is the most serious complication of osteoporosis and imposes a significant financial burden on countries' economy. This study aimed to assess the hospitalization costs and length of stay associated with osteoporosis hip fractures and identify the major cost components in a referral hospital in Kermanshah city, Iran. METHODS In a prospective study, from May 21 2007 to May 21 2008, all patients with osteoporotic hip fracture admitted to a referral hospital for operation were recruited as the study sample. For each patient, information such as age, gender, length of stay (LOS) in hospital and intensive care unit (ICU), medical and diagnostic procedures and cost of surgery and implant were collected both through interview with the patient or a family member and the patients' hospital records. RESULTS A total of 103 patients (56 men and 47 women) were studied. The average hospital length of stay (LOS) for the patients was 9.7 days, ranging from 5 to 38 days. The average total hospitalization costs was 7,208,588 IRR (US$774). The main components of the costs were ward stay (16.3%), operative (54.6%), implant (26%) and medical and diagnostic procedures (3.1%). CONCLUSIONS The results of this study demonstrate that the hospital resource burden associated with osteoporotic hip fractures in Iran is substantial and expected to rise with the projected increase of life expectancy and the number of elderly in Iran. Estimating the economic burden of osteoporotic hip fractures provide information that can be of importance in the planning and design of preventive strategies.

Intake of dehydrated nopal (Opuntia ficus indica) improves bone mineral density and calciuria in adult Mexican women. Food Nutr Res 2013; 57:19106. [PMID: 23704856 PMCID: PMC3661902 DOI: 10.3402/fnr.v57i0.19106] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2012] [Revised: 04/02/2013] [Accepted: 04/17/2013] [Indexed: 11/14/2022] Open
Abstract
Background The intake of dehydrated nopal (DN) at a high stage of maturity along with high calcium content could improve bone mineral density (BMD) and calciuria and thus prevent osteoporosis. Objective To evaluate the effect of calcium intake from a vegetable source (DN) on BMD and calciuria covering a 2-year period in menopausal and non-menopausal women with low bone mass (LBM). Methods The study was quasi-experimental, blinded, and randomized, and included 131 Mexican women aged 35–55. Urinary calcium/creatinine index (CCI) was determined; BMD was analyzed on lumbar spine and total hip regions. Four groups were studied: Control group (CG), women with normocalciuria and a minimum dose of DN; experimental group 1 (EG1), women with hypercalciuria and a minimum dose of DN; experimental group 2 (EG2), women with hypercalciuria, and a maximum dose of DN; and normal group (NG) for reference in BMD. Results After the first semester of treatment, calciuria levels in women from both experimental groups returned to normal, remaining constant for the rest of the treatment. The percentage difference in BMD increased in the total hip region in the CG (pre 4.5% and post 2.1%) and EG2 (pre 1.8% and post 2.5%) groups significantly in comparison to NG and EG1, which exhibited a significant decrease in their BMD. BMD increased only for the lumbar region in the EG2 group (premenopausal). Conclusion The use of a vegetable calcium source such as nopal improves BMD in women with LBM in the total hip and lumbar spine regions principally in the premenopausal women, maintaining constant and normal calciuria levels.

Health care costs of osteopenia, osteoporosis, and fragility fractures in Mexico. Arch Osteoporos 2013; 8:125. [PMID: 23526030 DOI: 10.1007/s11657-013-0125-4] [Citation(s) in RCA: 31] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2012] [Accepted: 12/12/2012] [Indexed: 02/03/2023]
Abstract
UNLABELLED Different sources were used to estimate the 2010 health care costs of managing low bone density (osteopenia/osteoporosis) plus caring fragility fractures in Mexico at 411 million USD. Figures are projected to rise 42 % by 2020. Preventive and timely interventions are required to decrease the financial burden of these entities. INTRODUCTION Osteopenia, osteoporosis, and fragility fractures (FF) are a public health concern. The study purpose was to estimate the health care costs of these conditions in Mexico during 2010 and project them to 2015 and 2020. METHODS Prevalence of osteopenia and osteoporosis was derived from international data. The Mexican version of FRAX® algorithm was used to assess risk for a major FF (hip, clinical spine, forearm, and proximal humerus) in osteopenic and osteoporotic population aged over 40 years. The estimates were applied to national demographic projections. Only direct medical costs composed by routine non-pharmacological management of osteopenia/osteoporosis besides the costs owing to medical care of major FF were considered into the analysis. Resource use for managing osteopenia/osteoporosis was defined from local sources (clinical practice guidelines, published literature, and expert opinion); unit costs were gathered from official lists. Costs for medical care of FF were based on diagnosis-related groups. RESULTS In population aged ≥40 years, prevalence of osteopenia and osteoporosis in 2010 was 32.8 and 8 %, respectively. A total of 75,763 FF occurred that year. Costs of managing osteopenia and osteoporosis were 154.9 million USD, whereas medical costs due to FF reached 256.2 million USD. Therefore, the annual health care costs of these entities in 2010 were 411 million USD. Total costs will be 19.2 % higher in 2015, and by 2020, the figures will have increased by 41.7 %. CONCLUSIONS Low bone density entails substantial epidemiological and financial burden in Mexico, and their impact will grow considerably during the next years.

Abstract
UNLABELLED To update the 1993 burden of illness of osteoporosis in Canada, administrative and community data were used to calculate the 2010 costs of osteoporosis at $2.3 billion in Canada or 1.3% of Canada's healthcare expenditures. Prevention of fractures in high-risk individuals is key to decrease the financial burden of osteoporosis. INTRODUCTION Since the 1996 publication of the burden of osteoporosis in 1993 in Canada, the population has aged and the management of osteoporosis has changed. The study purpose was to estimate the current burden of illness due to osteoporosis in Canadians aged 50 and over. METHODS Analyses were conducted using five national administrative databases from the Canadian Institute for Health Information for the fiscal-year ending March 31 2008 (FY 2007/2008). Gaps in national data were supplemented by provincial and community data extrapolated to national levels. Osteoporosis-related fractures were identified using a combination of most responsible diagnosis at discharge and intervention codes. Fractures associated with severe trauma codes were excluded. Costs, expressed in 2010 dollars, were calculated for osteoporosis-related hospitalizations, emergency care, same day surgeries, rehabilitation, continuing care, homecare, long-term care, prescription drugs, physician visits, and productivity losses. Sensitivity analyses were conducted to measure the impact on the results of key assumptions. RESULTS Osteoporosis-related fractures were responsible for 57,413 acute care admissions and 832,594 hospitalized days in FY 2007/2008. Acute care costs were estimated at $1.2 billion. When outpatient care, prescription drugs, and indirect costs were added, the overall yearly cost of osteoporosis was over $2.3 billion for the base case analysis and as much as $3.9 billion if a proportion of Canadians were assumed to be living in long-term care facilities due to osteoporosis. CONCLUSIONS Osteoporosis is a chronic disease that affects a large segment of the adult population and results in a substantial economic burden to the Canadian society.

Abstract
There is a dearth of information about the burden of osteoporosis in Canadian men. To fill this gap, we conducted a burden of illness study aimed at estimating the economic burden attributable to osteoporosis in Canadian men aged 50 years and older. Five national data sources were used to estimate health care resource utilization and costs (in 2010 Canadian dollars) associated with osteoporosis in men. Any information gap was supplemented by using data from provincial and community sources. Direct medical costs included costs associated with hospitalizations, same day surgeries, emergency room visits, rehabilitation, chronic care, long-term care, home care, physician visits, and prescribed medications. The value of lost productivity from patients and informal caregivers was also determined to provide a societal perspective. Sensitivity analyses were conducted to evaluate the impact of key assumptions on the results. In fiscal year 2007/2008, the total economic burden of treating and rehabilitating male osteoporotic fractures was estimated at $570 million per year, where direct medical costs accounted for 86%. Acute care utilization was responsible for 70% of all direct costs. About 51% of all hospitalizations were for hip fractures and hip fractures alone accounted for 54% of the acute care spending. If a proportion of Canadian men were assumed to live in long-term care facilities due to osteoporosis, the overall annual cost of osteoporosis would increase from $570 million to $910 million. Male osteoporosis has a substantial economic burden on the Canadian society.

Abstract
Background Few epidemiological data on hip fractures were previously available in Lithuania. The aim of this study was to estimate the incidence and hospital costs of hip fractures in Vilnius in 2010. Methods Data were collected from the medical charts of all patients admitted to hospitals in Vilnius (population, 548,835) due to new low-energy trauma hip fracture, during 2010. The estimated costs included ambulance transportation and continuous hospitalisation immediately after a fracture, which are covered by the Lithuanian healthcare system. Results The incidence of new low-energy trauma hip fractures was 252 (308 women and 160 men) per 100,000 inhabitants of Vilnius aged 50-years or more. There was an exponential increase in the incidence with increasing age. The overall estimated cost of hip fractures in Vilnius was 1,114,292 EUR for the year 2010. The greatest part of the expenditure was accounted for by fractures in individuals aged 65-years and over. The mean cost per case was 2,526.74 EUR, and cost varied depending on the treatment type. Hip replacement did not affect the overall mean costs of hip fracture. The majority of costs were incurred for acute (53%) and long-term care (35%) hospital stays, while medical rehabilitation accounted for only 12% of the overall cost. The costs of hip fracture were somewhat lower than those found in other European countries. Conclusion The data on incidence and costs of hip fractures will help to assess the importance of interventions to reduce the number of fractures and associated costs.

Abstract
Several studies have reported a positive relationship of the body fat mass and bone density. However, it is not clear whether adipocyte-derived signaling molecules directly act on osteoblasts or osteoclasts. Therefore, we investigated the effect of fat cell-secreted factors on the proliferation and differentiation of preosteoblasts and the molecular mechanisms involved. This stimulation led to an increased proliferation of MC3T3-E1 and primary preosteoblastic cells (2.8-fold and 1.5-fold, respectively; p<0.0001), which could be reduced with inhibitors of protein tyrosine kinases, FGFR1 and PI3K. Concordantly, we found human adipocytes to secrete bFGF and bFGF to mimic the effect of adipocyte-secreted factors. The ratio of OPG/RANKL secretion in primary human preosteoblasts increased 9-fold (mRNA and protein) when stimulated with adipocyte-secreted factors. Moreover, osteoblasts which were prestimulated with adipocyte-secreted factors inhibited the formation of osteoclasts. In conclusion, human adipocytes secrete factors that directly act on preosteoblasts and alter their crosstalk with osteoclasts. These in vitro findings reflect the higher bone mass in obese people and attribute it to effects of adipocyte-secreted factors on bone formation.

Abstract
Osteoporosis is a generalized disease of bone that increases fracture risk. Multiple factors influence this risk, besides low bone mass. To decrease osteoporotic fractures, those patients who require preventive management should be readily identified. This paper aims to review current information on the use of the fracture risk assessment tool (FRAX) in Latin America. Bone mineral density measurement is currently the method of reference for evaluating the fracture risk and opting for treatment; but, it misses a notable proportion of individuals who have clinical risk factors for osteoporosis and fractures. FRAX was designed to predict the 10-year absolute risk of sustaining a major osteoporotic fracture or a hip fracture. Although data is available for several countries, from Latin America, only Argentina appears in the current version of the tool. Its present use in other Latin American countries is possible with some adaptations based in similarities of epidemiological information of each country with some of the existing databases. The cutoff value beyond which treatment should be initiated needs to be determined, based not only on clinical criteria, but also on economic considerations.
