Abstract
BACKGROUND Delirium is thought to be common across various settings of care; however, still little research has been conducted in rehabilitation. AIM We investigated the prevalence of delirium, its features and motor subtypes in older patients admitted to rehabilitation facilities during the three editions of the "Delirium Day project". METHODS We conducted a cross-sectional study in which 1237 older patients (age ≥ 65 years old) admitted to 50 Italian rehabilitation wards during the three editions of the "Delirium Day project" (2015 to 2017) were included. Delirium was evaluated through the 4AT and its motor subtype with the Delirium Motor Subtype Scale. RESULTS Delirium was detected in 226 patients (18%), and the most recurrent motor subtype was mixed (37%), followed by hypoactive (26%), hyperactive (21%) and non-motor one (16%). In a multivariate Poisson regression model with robust variance, factors associated with delirium were: disability in basic (PR 1.48, 95%CI: 1.17-1.9, p value 0.001) and instrumental activities of daily living (PR 1.58, 95%CI: 1.08-2.32, p value 0.018), dementia (PR 2.10, 95%CI: 1.62-2.73, p value < 0.0001), typical antipsychotics (PR 1.47, 95%CI: 1.10-1.95, p value 0.008), antidepressants other than selective serotonin reuptake inhibitors (PR 1.3, 95%CI: 1.02-1.66, p value 0.035), and physical restraints (PR 2.37, 95%CI: 1.68-3.36, p value < 0.0001). CONCLUSION This multicenter study reports that 2 out 10 patients admitted to rehabilitations had delirium on the index day. Mixed delirium was the most prevalent subtype. Delirium was associated with unmodifiable (dementia, disability) and modifiable (physical restraints, medications) factors. Identification of these factors should prompt specific interventions aimed to prevent or mitigate delirium.

Abstract
Introduction Delirium and sarcopenia are common, although underdiagnosed, geriatric
syndromes. Several pathological mechanisms can link delirium and low skeletal muscle mass, but few studies have investigated their association. We aimed to investigate (1) the association between delirium and low skeletal muscle mass and (2) the possible role of calf circumference mass in finding cases with delirium. Methods The analyses were conducted employing the cross-sectional “Delirium Day” initiative, on patient 65 years and older admitted to acute hospital medical wards, emergency departments, rehabilitation wards, nursing homes and hospices in Italy in 2017. Delirium was diagnosed as a 4 + score at the 4-AT scale. Low skeletal muscle mass was operationally defined as calf circumference ≤ 34 cm in males and ≤ 33 cm in females. Logistic regression models were used to investigate the association between low skeletal muscle mass and delirium. The discriminative ability of calf circumference was evaluated using non-parametric ROC analyses. Results A sample of 1675 patients was analyzed. In total, 73.6% of participants had low skeletal muscle mass and 24.1% exhibited delirium. Low skeletal muscle mass and delirium showed an independent association (OR: 1.50; 95% CI 1.09–2.08). In the subsample of patients without a diagnosis of dementia, the inclusion of calf circumference in a model based on age and sex significantly improved its discriminative accuracy [area under the curve (AUC) 0.69 vs 0.57, p < 0.001]. Discussion and conclusion Low muscle mass is independently associated with delirium. In patients without a previous diagnosis of dementia, calf circumference may help to better identify those who develop delirium.

Abstract
Three cases of connective tissue tumors causing hypophosphatemic osteomalacia are reported and the literature is reviewed. In two of our patients the tumors were completely excised with total disappearance of the symptoms. In one case a total excision was not possible and the symptoms of this patient have not completely disappeared. The substance responsible for the syndrome has not been identified yet, but probably interferes with vitamin D renal hy-droxylation, thus causing osteomalacia. As more than 30 per cent of cases of this condition have been reported in the last 5 years, it is suggested that these tumors are more frequent than previously believed.

Abstract
PURPOSE The study was aimed at evaluating the prevalence of osteoporosis, defined by BMD and the National Bone Health Alliance (NBHA) criteria, and the prevalence of clinical risk factors for fractures in Italian postmenopausal women. METHODS This is a cross-sectional, multicenter, cohort study evaluating 3247 postmenopausal women aged ≥ 50 and older in different areas of Italy in the period 2012-2014. All the participants were evaluated as far as anthropometrics; questionnaires for FRAX® and DeFRA calculation were administered and bone mineral density was measured at lumbar spine, femoral neck and total hip by DXA. RESULTS The prevalence of osteoporosis, as assessed by BMD and NBHA criteria was 36.6 and 57%, respectively. Mean ± SD values of FRAX® and DeFRA were: 10.2 ± 7.3 and 11 ± 9.4 for major fractures, and 3.3 ± 4.9 and 3.9 ± 5.9 for hip fractures, respectively. Among clinical risk factors for fracture, the presence of previous fracture, particularly non-spine/non-hip fracture, parental history of hip fracture and current smoking were the most commonly observed. CONCLUSIONS Our study showed that more that the half of postmenopausal women aged 50 and older in Italy has osteoporosis on the basis of the NBHA criteria. There is a relevant high risk of femur fracture, as assessed by the FRAX® and DeFRA and previous fracture, parental history of hip fracture and current smoking are the most common risk factors. The data should be considered particularly in relation to the need to increase prevention strategies on modifiable risk factors and therapeutic intervention.

Abstract
UNLABELLED Osteoporosis treatment has low adherence and persistence. This study evaluated if greater patient involvement could improve them. At 12 months, only 114 out of 344 participants were "fully adherent and persistent" (all drug doses taken throughout the study). Only frequency of drug administration had a significant influence on adherence. INTRODUCTION Osteoporosis affects millions of individuals worldwide. There are now several effective drugs, but adherence to and persistence with treatment are low. This 12-month multicenter, prospective, randomized study evaluated the efficacy of two different methods aimed at improving adherence and persistence through greater patient involvement, compared with standard clinical practice. METHODS Three hundred thirty-four post-menopausal women, receiving an oral prescription for osteoporosis for the first time, were recruited and randomized into three groups: group 1 (controls, managed according to standard clinical practice) and groups 2 and 3 (managed with greater patient and caregiver involvement and special reinforcements: group 2, instructed to use several different "reminders"; group 3, same "reminders" as group 2, plus regular phone calls from and meetings at the referring Center). All enrolled women had two visits (baseline and 12 months). RESULTS Of 334 enrolled women, 247 (74%) started the prescribed therapy. Of those who started, 219 (88.7%) persisted in therapy for at least 10 months. At final evaluation, only 114 women were considered as "fully adherent and persistent" (all doses taken throughout the 12 months). There were no significant differences regarding "full adherence" among the three randomized groups. The frequency of drug administration had a significant influence: weekly administration had a >5-fold higher adherence and monthly administration an 8-fold higher adherence (p < 0.0001) than daily administration. CONCLUSIONS The special effort of devising and providing additional reminders did not prove effective. Additional interventions during the follow-up, including costly interventions such as phone calls and educational meetings, did not provide significant advantages.

Abstract
AIM The decrease in bone density may occur as a result of inflammatory bowel disease (IBD). Studies conducted on this issue generally focused on treated IBD patients. It is thus difficult to discriminate the role of disease from the effect of therapy on bone density reduction. We evaluated the prevalence of osteopenia/osteoporosis and abnormalities in indices of bone metabolism in patients with newly diagnosed IBD. METHODS Evaluation of dual-energy X-ray absorptiometry (DXA) at the lumbar spine and intact parathormone (PTH), 25-hydroxy vitamin D and urinary cross-links, on 37 (26 females, median age 35.6±14.5 years) consecutive patients. RESULTS Sixteen of 37 patients (43%) had normal DXA, 17 (46%) were osteopenic and 4 (11%) osteoporotics. Most male patients >30 years (63%) old as well as young women (62%) had osteopenia/osteoporosis. Mean value of intact-PTH was significantly higher in women >50 years (55.0±18.1 pg/mL) compared with those aged 16-20 years (30.0±14.6 pg/mL) (P=0.042). Furthermore, there was a significant difference between mean value of 25-hydroxy vitamin D in women >50 years old (16.2±4.7 ng/mL) compared to those aged 21-30 years (26.6±7.9 ng/mL) (P=0.041). Intact-PTH was significantly higher in osteoporotic patients (55.7±12.7 pg/mL) compared to normal subjects (28.3±13.0 pg/mL) (P=0.0014). CONCLUSION High prevalence of osteopenia/osteoporosis was observed in this population. On the basis of these data, we propose to perform DXA in male patients aged >30 years and in all women with new diagnosis of IBD.

Abstract
AIM It is well known that vitamin D plays an important role in maintaining bone homeostasis and in regulating calcium absorption. The active form of vitamin D interacts with its receptor the VDR that is expressed in multiple tissues and it is involved in platelets (PLTs) function. In the present study we evaluate PLTs' VDR expression in osteoporotic as opposed to healthy subjects. METHODS We enrolled in the study 77 women with postmenopausal osteoporosis, 33 healthy women of childbearing age, 49 healthy men, and 11 healthy women matched with patients for age and postmenopausal period. Thirty-nine patients had had one femoral fracture occurred after the age of fifty and attributable to primary osteoporosis. Bone mineral density, markers of bone metabolism and VDR levels were measured in all the subjects. RESULTS Our data show that VDR level is lower in patients as respect to controls and is positively correlated with bone density, but not with markers of bone metabolism. We also found a decrease in the phosphorus levels in patients without differences in vitamin D levels and in the dietary calcium intake. CONCLUSION The lower VDR expression in osteoporotic could indicate a lower ability to respond to vitamin D, and could be the explanation of the increase in the PTH and decrease in the phosphorus levels in patients with respect to controls.

Abstract
The efficacy of clodronate to reduce bone loss around uncemented stems after total hip arthroplasty(THA) was evaluated. Ninety-one patients operated with uncemented THA were randomized to receive either intramuscular clodronate at a dose of 100 mg weekly for 12 months or no treatment. Periprosthetic and contralateral bone mineral density (BMD) scans were performed and biochemical markers of bone turnover measured at baseline and at 3, 6, and 12 months. At month 12, with the exception of Gruen zones 4 and 5, patients treated with clodronate showed less bone loss at all zones, reaching statistical significance (P\0.05) in Gruen zones 2 and 6 (difference of 6.6 and 5.9%, respectively). Analysis of data according to gender revealed sex-related differences in bone loss and efficacy of treatment. After 12 months, the difference in bone loss between treated and untreated women in five out of seven Gruen zones ranged from 6.2 to 13.3% (SS at zones 2 and 6), whereas comparison between treated and untreated men showed no BMD differences in all zones(P[0.05). Median percent changes in serum levels of markers of bone metabolism by gender were consistent with BMD changes. A 1-year treatment with intramuscular clodronate determined a significant reduction of bone loss after THA. This was mainly attributed to its greater efficacy in the female population, which is at higher risk for bone loss. This observation suggests the need for the characterization of high-risk subjects as potential candidates for prevention strategies.

Abstract
In 2000, Alzheimer's disease (AD) and other dementias were the third most expensive health conditions in the USA and in 2005 their annual costs amounted to more than $148 billion. An observational, non-randomized study aimed to evaluate direct costs of demented patients in their homes. Two hundred thirty-six informal caregivers have been enrolled. A financial support, represented by a disability living allowance (15.3%) or attendance allowance (3.4%), was presented in just 19.7% of the cases. Patients receiving assistance from an employed carer were 39% with a mean cost of 800 Euro/month. Receiving assistance from an employed carer is not correlated with cognitive and functional impairment, with the age of the caregiver and with the duration of the disease (t=1.03; t=-0.86; t=1.41; t=-0.16, respectively). The informal caregivers declared that they thoughts about the possibility of institutionalize the patient were 20.9%. The present study underlines the discrepancy between subjects having assistance from an employed caregiver and subjects receiving financial supports. It often happens that patients not reaching the minimum requisites for social assistant or financial support, need at least a supervision.

Abstract
BACKGROUND Osteoporosis is the most common skeletal disorder in the elderly, being characterized by impaired bone strength and increased risk of fracture. Severe osteoporosis is currently defined by the threshold of bone density value below the -2.5 SDS of T-score, determined by dualenergy X-ray absorptiometry, and the presence of one or more fragility fractures. This definition does not entirely reflect the spectrum of severity of the disease that provides a variable increase in fracture risk. METHODS This manuscript reports a consensus statement on the diagnostic criteria for severe osteoporosis in real-life clinical setting, achieved in an event held by Italian physicians with expertise in osteoporosis and metabolic bone diseases. RESULTS The group stated that a large number of fractures occur in subjects with T-score above -2.5. In light of recent advances on the structural basis of skeletal fragility, it became clear that bone density represents only one of the contributors to bone strength and number and severity of fragility fractures. The group suggests that the condition of two or more fragility fractures should be considered as severe osteoporosis, independently of bone density. CONCLUSIONS The consensus statement proposes a more specific definition of severe osteoporosis, which should consider not only densitometric measurements, but also the number and severity of fragility fractures. Patients' management and choice of treatment should take into consideration the type and severity of osteoporotic fractures, in addition to bone density.

Abstract
SUMMARY Vertebral fractures are a major adverse consequence of osteoporosis. In a large placebo-controlled trial in postmenopausal women with osteoporosis, strontium ranelate reduced vertebral fracture risk by 33% over 4 years, confirming the role of strontium ranelate as an effective long-term treatment in osteoporosis. INTRODUCTION Osteoporotic vertebral fractures are associated with increased mortality, morbidity, and loss of quality-of-life (QoL). Strontium ranelate (2 g/day) was shown to prevent bone loss, increase bone strength, and reduce vertebral and peripheral fractures. The preplanned aim of this study was to evaluate long-term efficacy and safety of strontium ranelate. METHODS A total of 1,649 postmenopausal osteoporotic women were randomized to strontium ranelate or placebo for 4 years, followed by a 1-year treatment-switch period for half of the patients. Primary efficacy criterion was incidence of patients with new vertebral fractures over 4 years. Lumbar bone mineral density (BMD) and QoL were also evaluated. RESULTS Over 4 years, risk of vertebral fracture was reduced by 33% with strontium ranelate (risk reduction = 0.67, p < 0.001). Among patients with two or more prevalent vertebral fractures, risk reduction was 36% (p < 0.001). QoL, assessed by the QUALIOST(R), was significantly better (p = 0.025), and patients without back pain were greater (p = 0.005) with strontium ranelate than placebo over 4 years. Lumbar BMD increased over 5 years in patients who continued with strontium ranelate, while it decreased in patients who switched to placebo. Emergent adverse events were similar between groups. CONCLUSION In this 4- and 5-year study, strontium ranelate is an effective and safe treatment for long-term treatment of osteoporosis in postmenopausal women.

Abstract
Osteoporosis and atherosclerosis are degenerative disorders of old age that often present together, but recently it has been suggested that the association between osteoporosis and cardio-vascular diseases is not just due to the aging process. The osteoprotegerin (OPG)/receptor activator of nuclear factor-kB (RANK)/RANK ligand (RANKL) system has been identified as a possible mediator of arterial calcification suggesting common links between osteoporosis and vascular diseases. Since the discovery of the OPG/RANK/RANKL system, much has been learned about its role in controlling skeletal biology; however, its role in the context of vascular biology is only beginning to be explored. It has been suggested that OPG might act as an autocrine/paracrine regulator of vascular calcification and might be useful as a serum marker of vascular disease. However, the exact role of OPG (or RANKL/RANK) in vascular calcification is still not completely understood. This review aims to report the recent findings on the relationship between osteoporosis and OPG/RANK/RANKL-mediated vascular disease.

Abstract
OBJECTIVES Early osteoporotic fractures have a great impact on disease progression, the first fracture being a major risk factor for further fractures. Strontium ranelate efficacy against vertebral fractures is presently assessed in a subset of women aged 50-65 years. METHODS The Spinal Osteoporosis Therapeutic Intervention (SOTI) was an international, double blind, placebo controlled trial, supporting the efficacy of strontium ranelate 2 g/day in reducing the risk of vertebral fractures in postmenopausal women with osteoporosis and a prevalent vertebral fracture. 353 of these randomly assigned women were included in this analysis. RESULTS Over 4 years, strontium ranelate significantly reduced the risk of vertebral fracture by 35% (relative risk 0.65; 95% CI 0.42 to 0.99, p<0.05). In the strontium ranelate group, the bone mineral density increased from baseline by 15.8% at lumbar spine and 7.1% at femoral neck. CONCLUSION These data demonstrate a significant vertebral antifracture efficacy of strontium ranelate in young postmenopausal women aged 50-65 years with severe osteoporosis and confirm the efficacy of this antiosteoporotic treatment to prevent vertebral fractures, whatever the age of the patient.

Abstract
UNLABELLED None of the available osteoporosis therapies completely abolish the risk of fracture. Among 862 patients on treatment with antiresorptive agents (alendronate, risedronate, and raloxifene) for >1 year a fragility fracture was observed in 9.5%/year. This incidence is considerably higher than that observed in randomized clinical trials. INTRODUCTION Available osteoporosis therapies reduced in randomized controlled trials (RCTs) the risk of fracture by 30-50%. The proportion of patients suffering from new fractures while on active treatment ("inadequate clinical treatment response" or ICR) can be derived from the data of the RCTs, where confounding factors are usually controlled by the exclusion criteria. In the retrospective part of the ICARO study we observed a 8.9% annual incidence of ICR. Here we report the results of the longitudinal part of the study. METHODS The study includes 862 women with severe postmenopausal osteoporosis. Ninety-two of these patients (10.7%) were defined as having ICR (9.5%/year) during therapy with antiresorptive drugs (alendronate, risedronate, and raloxifene) for at least 1 year. RESULTS The ICR patients were comparable to patients who did not sustain clinical fractures with regard to body mass index, follow-up duration, number of prevalent vertebral fractures, type of osteoporosis treatment, proportion of patients taking calcium and vitamin D supplements, and compliance with treatment. Those with ICR were significantly older (p=0.032) and more frequently had multiple vertebral deformities (p=0.013). CONCLUSIONS The incidence of ICR during treatment with antiresorptive agents among patients with severe postmenopausal osteoporosis in a routine setting is considerably higher than that observed in randomized clinical trials.

Abstract
AIM Epidemiological investigation of the association between lipid profile, atherosclerosis and bone mass has produced conflicting RESULTS The present paper reports the assessment of the lipid profile, bone mineral density (BMD) and turnover in a cohort of Italian women. METHODS In this cross sectional study we enrolled 173 women in menopause (101 osteoporotic and 72 normal). In each subject the authors evaluated BMD, bone turnover, lipid profile (total cholesterol, high density lipoprotein [HDL], low density lipoprotein [LDL] and triglycerides), and risk factors for osteoporosis, cardiovascular diseases and eating habits using a questionnaire. RESULTS HDL was significantly higher in osteoporotic patients than in controls and the risk of osteoporosis was significantly higher in women with higher level of HDL. The authors suggest that the level of HDL could be used as screening for postmenopausal osteoporosis: the cut-off points recommended are HDL >61 mg/dL to detect women with a high risk (sensitivity 74%) and <45 mg/dL to detect those with a low risk (specificity 83%). CONCLUSION This study provides evidences of the relation between HDL, but not total cholesterol or LDL levels with BMD in a cohort of normal-weight women and equally distributed cardiovascular risks. It also suggests that a proatherogenic lipid profile is associated with higher bone mineral density, and that HDL can be used in deciding whether a patient's BMD should be measured.

Abstract
UNLABELLED Strontium ranelate reduces the risk of fracture in post-menopausal osteoporotic women with prevalent fractures for whom quality of life is severely impaired. The SOTI study, which used the SF-36 questionnaire and disease-specific QUALIOST module, demonstrated that treatment with strontium ranelate improved osteoporotic women's quality of life compared with placebo. INTRODUCTION The Spinal Osteoporosis Therapeutic Intervention (SOTI) study demonstrated the effect of orally administered strontium ranelate versus placebo on the incidence of new vertebral fractures and compared impact on quality of life (QoL). METHODS QoL was assessed 6 monthly over 3 years using the QUALIOST and SF-36 questionnaires in post-menopausal osteoporotic women with prevalent fracture taking strontium ranelate or placebo 2 g/day. A total of 1,240 women were included (strontium ranelate: n=618 and placebo: n=622). RESULTS The QUALIOST total score decreased in the strontium ranelate group, indicating preserved QoL compared with a deterioration in the placebo group (P=0.016). Strontium ranelate patients had reduced QUALIOST emotional and physical dimension scores (P=0.019 and 0.032, respectively, versus placebo), indicating beneficial effects on emotional and physical functioning. There was a trend towards better SF-36 scores in the strontium ranelate group, although there were no significant between-group differences. More strontium ranelate patients (+31%) were free from back pain over 3 years versus placebo (P=0.005), with a significant effect from the first year of treatment (P=0.023). CONCLUSION Strontium ranelate has beneficial effects on QoL in women with post-menopausal osteoporosis compared with placebo.

Abstract
OBJECTIVE Strontium ranelate (SR) increases bone mineral density (BMD) in postmenopausal osteoporotic women and reduces vertebral and non-vertebral fracture incidence. Hip fracture reduction has also been observed during 3-year treatment with SR in osteoporotic women at high risk of hip fracture. The objective of this study is to analyse the association between BMD changes and hip fracture incidence during treatment with SR. MATERIAL AND METHODS In this post-hoc analysis, 465 women aged over 74 years with low BMD at the femoral neck (T-score < or = -2.4 according to NHANES normative values) were selected from the population of a recently published study (the Treatment of Peripheral Osteoporosis Study - TROPOS). BMD was assessed at the femoral neck at baseline and after a follow-up of 3 years. Hip fractures were reported by study investigators. RESULTS After adjusting for age, body mass index, femoral neck BMD at baseline and number of prevalent vertebral fractures, we found that for each 1% increase in femoral neck BMD observed after 3 years, the risk to experience a hip fracture after 3 years decreased by 7% (95% CI: 1-14%) (p = 0.04). In patients experiencing a hip fracture over 3 years of treatment with SR, femoral neck BMD increased by (mean [SE]) 3.41 (1.02)% compared to 7.23 (0.81)% in patients without hip fracture (p = 0.02). CONCLUSION In this post-hoc analysis of women undergoing 3 years of SR treatment, an increase in femoral neck BMD is associated with a decrease in hip fracture incidence.

Abstract
Quantitative ultrasound (QUS) is a reliable technique to evaluate skeletal status, to identify osteoporotic subjects, and to estimate the risk of fractures. The purpose of this study was to generate QUS normative data for Italian females and males aged 60-79 yr participating in the Epidemiologic Study on the Prevalence of Osteoporosis (ESOPO) study, using the Achilles Plus apparatus. ESOPO is a cross-sectional study conducted in 2000, aiming at assessing risk of osteoporosis in a random sample of 11,011 women and 4981 men, representative of the Italian population. All participants were administered a questionnaire on the most relevant risk factors for osteoporosis and fractures; 3 QUS parameters were also measured: broadband ultrasound attenuation (BUA); speed of sound (SOS); and Stiffness Index (SI). We studied the age-dependent changes in QUS values, and their correlation with body size. For both men and women, weight was the variable with the highest correlation with BUA and SI; for SOS, age among women and body mass index (BMI) among men presented the highest correlation coefficients. Average decreases of 3.0% in BUA, 0.8% in SOS, and 9.1% in SI from 60 to 79 yr were detected for females, whereas no significant changes with age in males were observed. Our data show lower QUS values for women, and a decline at a greater rate than in men.

Abstract
Some studies have suggested that hypovitaminosis D may be a consequence of protein-calorie malnutrition. This study assessed both the relationship between vitamin D status, malnutrition, calcium and phosphorus metabolism indices and the importance attached by internists to these alterations. There were 239 patients admitted to an internal medicine division who underwent examinations to assess nutritional state, liver and renal function, and bone metabolism. At the end of the study, the clinical data included in the discharge letter, the treatment prescribed, and the diagnosis assigned to patients on their hospital discharge form were collected. Hypovitaminosis D was found in 72% and hypoalbuminemia in 34.3% of patients. Subjects with hypovitaminosis were generally older and had lower albumin levels than those with mild or no hypovitaminosis. 25-Hydroxyvitamin D was inversely related with parathyroid hormone and directly related with albumin. Alterations of calcium and phosphorus metabolism were present in 55.6% and recorded by the division's physicians for only 13.53% of patients, of whom 72.37% were not specifically treated. There is a direct correlation between 25-hydroxyvitamin D and albumin levels. The high incidence and the metabolic consequence of hypovitaminosis D and of protein-calorie malnutrition is significantly underestimated and undertreated by physicians.

Abstract
Bone density depends on various factors such as age, hormonal status, genetics factors and lifestyle: a balanced diet plays a fundamental role in the prevention of osteoporosis. The role of protein intake on bone health is still controversial: this review is focused on the relation between protein intake and bone metabolism.

Abstract
We assessed the clinical usefulness of quantitative ultrasound (QUS) in defining the prevalence rates of osteoporosis and osteopenia and their association with fractures of the forearm, vertebrae, and hip. The ESOPO study was conducted in 2001 and assessed a random sample of 11,011 women and 4,981 men, in 83 centers spread all over Italy. A large array of risk factors was investigated, and self-reported history of fractures was collected in a questionnaire. After the patient had undergone interview and a brief physical examination, QUS of the heel was performed, using the Achilles apparatus (GE-Lunar, Madison, USA). The prevalence rate of osteoporosis in women 40-79 years old was approximately 18.5%, while the rate of osteopenia was about 44.7%; in men 60-79 years of age the rates were 10% and 36%, respectively. A strong association with fractures was found for osteoporosis and osteopenia in both men and women, independently of all traditional risk factors, including age. These results confirm the suitability of US measurements as a tool for detecting individuals at risk of fractures.

Abstract
In order to evaluate the usefulness of calcaneal quantitative ultrasound (QUS) in the assessment of male osteoporosis, a cross-sectional, population-based study was performed. A cohort of 4,832 men, randomly selected, community-dwelling, aged 60-80 years and representative of the general older male Italian population was recruited. QUS measurements were assessed in 83 centers distributed all over Italy and equipped with an Achilles device (GE-Lunar, Madison, Wisconsin, USA). All participants were administered a questionnaire covering lifestyle variables and medical history. Low-energy fractures that had occurred since age 50 were recorded. Overall, 43 subjects reported a previous hip fracture and 455 subjects reported other non-spinal fractures. Univariate analysis showed that fractured subjects were older, with a lower level of outdoor physical activity and a more frequent history of prolonged bedridden periods in comparison with unfractured subjects. Men reporting non-spinal fractures showed a higher prevalence of smoking, while no difference was found among groups in anthropometric measures and calcium intake. QUS measurements showed that all QUS parameters were significantly lower in both fracture groups (p<0.001). Multiple logistic regression analysis demonstrated that each SD reduction in QUS measures was associated with an approximate doubling of the risk for hip fracture, independent of age and other clinical variables (broadband ultrasound attenuation [BUA]: odds ratio [OR]=2.24; 95% confidence interval [CI] 1.61-3.08; stiffness index: OR=2.19; CI 1.56-3.11; speed of sound [SOS]: OR=1.71; CI 1.18-3.24) and with an increase of the risk of other non-spinal fractures (BUA: 1.38; CI 1.22-1.59; stiffness index: OR=1.27; CI 1.17-1.38; SOS: OR=1.14; CI 0.96-1.40). It can be concluded that calcaneal QUS measurement is associated with the risk for hip fracture and any non-spinal fractures among a community-dwelling cohort of elderly men. The strength of the association between QUS measurement and fracture is similar to that observed in elderly women.

Abstract
In this study the authors analyzed the role of risk factors in postmenopausal osteoporosis in a cohort of Italian women and evaluated predictive values of decision rules for early identification of osteoporotic women. Furthermore, the authors investigated the prevalence of secondary osteoporosis in this population. Women who underwent bone densitometry were asked to answer a questionnaire about the common risk factors for osteoporosis. Patients were classified as nonosteoporotic, nonosteopenic, and osteoporotic. Risk factors were compared among the groups by use of analysis of variance (ANOVA). National Osteoporosis Foundation (NOF) recommendation, Osteoporosis Risk Assessment Instruments (ORAIs), Osteoporosis Self-Assessment Tools (OST) score, and weight criterion were applied to this population. The authors proposed a new decision rule based on a new score. A total of 525 women received the questionnaire: 47.4% women were osteoporotic, 32.2% were osteopenic, and 20.4% nonosteoporotic. Risk factors that differed significantly between these groups were: age, age at menarche, postmenopausal period, and body mass index (BMI); the aforementioned risk factors appear to be significant predictors of bone density (BMD) in linear regression model. The incidence of secondary osteoporosis was 13%. In conclusion, the authors (1) confirmed the role played by nonmodifiable risk factors in determining BMD; (2) showed that the use of NOF guidelines, ORAI, OST score, and weight criterion is not satisfactory in our cohort; (3) suggested a new score, based upon the features that were significantly different between patients and controls; and (4) demonstrated the relatively high prevalence of secondary osteoporosis and suggest a primary screening for secondary osteoporosis in all patients with low BMD.

Abstract
BACKGROUND AND AIM The relationships between C-reactive protein (CRP) levels, adipose tissue and metabolic alterations have not been clearly established in healthy non-obese subjects. We investigated the relationships between body fat, CRP levels and metabolic variables in healthy, non-obese sons of patients affected by metabolic syndrome (MS). METHODS AND RESULTS Age, CRP and interleukin 6 (IL-6) levels, anthropometric measures (body mass index, BMI; waist circumference and waist-to-hip ratio, WHR), total and regional fat content (as determined by means of dual X-ray absorptiometry, DXA), total and LDL cholesterol, and the metabolic variables related to MS (HDL-cholesterol, triglyceride, glucose and insulin levels; the fasting insulin resistance index, FIRI; blood pressure) were evaluated in 85 healthy non-obese sons of MS patients. Linear and multiple regression analyses were used to evaluate the relationships between body fat, metabolic variables and CRP levels, and to investigate whether the association between body fat content and metabolic variables persists after adjustment for CRP levels. Body fat was associated with all of the investigated variables. CRP levels were associated with total and regional body fat, the anthropometric index of weight, age, and with some metabolic alterations (HDL-cholesterol and triglyceride levels, systolic blood pressure, and fasting insulin and LDL-cholesterol levels). The associations between total body fat and the metabolic variables did not change after adjustment for CRP levels. Total body fat was the best predictor of CRP levels (p<0.0001). CONCLUSIONS In healthy, non-obese sons of MS patients, total body fat is the best predictor of CRP levels, and remains closely associated with metabolic abnormalities after adjustment for CRP levels. These findings strongly support the hypothesis that body fat is the main determinant of metabolic abnormalities and a low inflammatory state, at least in healthy subjects.

Abstract
In order to evaluate the prevalence, risk factors, and clinical consequences of hypovitaminosis D in elderly Italian women a multicenter study of 43 osteoporosis centers from all regions of Italy was carried out. Study population included 700 women aged 60-80 years in whom blood was taken for 25-hydroxyvitamin D (25OHD) and parathyroid hormone (PTH) measurements. All subjects were also questioned to assess the prevalence of several risk factors for hypovitaminosis D, osteoporotic fractures and activities of daily living (ADL). Values of 25OHD lower than 5 ng/ml were found in 27% of the women and lower than 12 ng/ml in 76%. 25OHD and PTH levels were negatively correlated ( r=-0.38, after logarithmic transformation of both variables). 25OHD levels significantly declined with advancing age and number of pregnancies and were positively correlated with educational level (years spent at school), dairy calcium intake, and days spent on holiday by the sea. In a multivariate model including all these variables, the only one that remained significant was the level of education. The lowest age-adjusted 25OH D levels were found in smokers or in women living in central Italy as compared with those living in northern or southern Italy. The mean (+/-SD) age-adjusted 25OH D values were significantly lower in women who sustained a hip fracture (7.1+/-2.2 versus 11.0+/-9.9). Women with low 25OHD levels (<12 ng/ml) had worse scores for ADL and mobility ADL (move outdoors, use stairs, walk at least 400 m, carry a heavy object). Vitamin D deficiency is extremely common among elderly Italian women. Women with lower educational level, living in central Italy, smokers or with lower intake of dairy products are at greater risk. Hypovitaminosis D is associated with worsening of the ability to perform activities of daily living and higher hip fracture prevalence. This finding should lead to an urgent population-based strategy to remedy this condition.

Abstract
BACKGROUND Osteoporosis is a recognized complication of primary biliary cirrhosis but it has been suggested that its prevalence may overlap that observed among postmenopausal women. AIM To evaluate prevalence and risk factors of osteoporosis in primary biliary cirrhosis. PATIENTS A total of 133 female patients (age 53+/-10 years, menopausal status 70%, histological stage I-II 61%, portal hypertension 28%, Mayo Risk Score 4.11+/-0.59) were enrolled. METHODS Dual X-ray absorptiometry of the lumbar spine. RESULTS Mean bone mineral density, T and Z score were 0.861+/-0.160 g/cm2, -1.87+/-1.45 and -0.78+/-2.63, respectively. At multivariate analysis, bone mineral density was inversely correlated with age (p<0.05). Osteoporosis was present in 39/92 (41%) postmenopausal and 8/41 (20%) premenopausal patients. In the premenopausal group, osteoporosis was significantly correlated with serum albumin (p<0.05) and Mayo Risk score (p<0.005). No significant correlation was present in the postmenopausal group. CONCLUSIONS Despite the accepted wisdom that osteoporosis is a common complication of primary biliary cirrhosis, its frequency in post-menopausal patients overlaps that observed in the general population, but is much more frequent in premenopausal patients, where it appears to be related to severity of liver disease and cholestasis.

Abstract
Risedronate treatment reduces the risk of vertebral fracture in women with existing vertebral fractures, but its efficacy in prevention of the first vertebral fracture in women with osteoporosis but without vertebral fractures has not been determined. We examined the risk of first vertebral fracture in postmenopausal women who were enrolled in four placebo-controlled clinical trials of risedronate and who had low lumbar spine bone mineral density (BMD) (mean T-score = -3.3) and no vertebral fractures at baseline. Subjects received risedronate 5 mg ( n = 328) or placebo ( n = 312) daily for up to 3 years; all subjects were given calcium (1000 mg daily), as well as vitamin D supplementation (up to 500 IU daily) if baseline serum 25-hydroxyvitamin D levels were low. The incidence of first vertebral fracture was 9.4% in the women treated with placebo and 2.6% in those treated with risedronate 5 mg (risk reduction of 75%, 95% confidence interval 37% to 90%; P = 0.002). The number of patients who would need to be treated to prevent one new vertebral fracture is 15. When subjects were stratified by age, similar significant reductions were observed in patients with a mean age of 64 years (risk reduction of 70%, 95% CI 8% to 90%; P = 0.030) and in those with a mean age of 76 years (risk reduction of 80%, 95% CI 7% to 96%; P = 0.024). Risedronate treatment therefore significantly reduces the risk of first vertebral fracture in postmenopausal women with osteoporosis, with a similar magnitude of effect early and late after the menopause.

Abstract
In vivo studies have shown T cells to be central to the mechanism by which estrogen deficiency induces bone loss, but the mechanism involved remains, in part, undefined. In vitro, T cells from ovariectomized mice produce increased amounts of tumor necrosis factor (TNF), which augments receptor activator of NF-kappa B ligand (RANKL)-induced osteoclastogenesis. However, both the mechanism and the relevance of this phenomenon in vivo remain to be established. In this study, we found that ovariectomy increased the number of bone marrow T cell-producing TNF without altering production of TNF per T cell. Attesting to the essential contribution of TNF, ovariectomy induced rapid bone loss in wild type (wt) mice but failed to do so in TNF-deficient (TNF(-/-)) mice. Furthermore, ovariectomy induced bone loss, which was absent in T cell-deficient nude mice, was restored by adoptive transfer of wt T cells, but not by reconstitution with T cells from TNF(-/-) mice. These findings demonstrate the key causal role of T cell-produced TNF in the bone loss after estrogen withdrawal. Finally, ovariectomy caused bone loss in wt mice and in mice lacking p75 TNF receptor but failed to do so in mice lacking the p55 TNF receptor. These findings demonstrate that enhanced T cell production of TNF resulting from increased bone marrow T cell number is a key mechanism by which estrogen deficiency induces bone loss in vivo. The data also demonstrate that the bone-wasting effect of TNF in vivo is mediated by the p55 TNF receptor.

Abstract
In a large proportion of the patients with primary hyperparathyroidism (PHPT), a variable degree of osteopenia is the only relevant manifestation of the disease. Low bone mineral density (BMD) in patients with PHPT is an indication for surgical intervention because successful parathyroidectomy results in a dramatic increase in BMD. However, low BMD values are almost an invariable finding in elderly women with PHPT, who are often either unwilling or considered unfit for surgery. Bisphosphonates are capable of suppressing parathyroid hormone (PTH)-mediated bone resorption and are useful for the prevention and treatment of postmenopausal osteoporosis. In this pilot-controlled study, we investigated the effects of oral treatment with alendronate on BMD and biochemical markers of calcium and bone metabolism in elderly women presenting osteoporosis and mild PHPT. Twenty-six elderly patients aged 67-81 years were randomized for treatment with either oral 10 mg alendronate on alternate-day treatment or no treatment for 2 years. In the control untreated patients a slight significant decrease was observed for total body and femoral neck BMD, without significant changes in biochemical markers of calcium and bone metabolism during the 2 years of observation. Urine deoxypyridinoline (Dpyr) excretion significantly fell within the first month of treatment with alendronate, while serum markers of bone formation alkaline phosphatase and osteocalcin fell more gradually and the decrease became significant only after 3 months of treatment; thereafter all bone turnover markers remained consistently suppressed during alendronate treatment. After 2 years in this group we observed statistically significant increases in BMD at lumbar spine, total hip, and total body (+8.6 +/- 3.0%, +4.8 +/- 3.9%, and +1.2 +/- 1.4% changes vs. baseline mean +/- SD) versus both baseline and control patients. Serum calcium, serum phosphate, and urinary calcium excretion significantly decreased during the first 3-6 months but rose back to the baseline values afterward. Increase in serum PTH level was statistically significant during the first year of treatment. These preliminary results may make alendronate a candidate as a supportive therapy in patients with mild PHPT who are unwilling or are unsuitable for surgery, and for whom osteoporosis is a reason of concern.

Abstract
OBJECTIVE We studied whether oral administration of ipriflavone, a synthetic derivative of naturally occurring isoflavones, could prevent bone loss occurring shortly after menopause. DESIGN Fifty-six women with low vertebral bone density and with postmenopausal age less than five years were randomly allocated to receive either ipriflavone, 200 mg three times daily, or placebo. All subjects also received 1,000 mg elemental calcium daily. RESULTS Vertebral bone density declined after two years in women taking only calcium (4.9 +/- 1.1%, SEM, p = 0.001), but it did not change in those receiving ipriflavone (-0.4 +/- 1.1%, n.s.). A significant (p = 0.010) between-treatment difference was evidenced at both year 1 and year 2. At the end of the study, urine hydroxyproline/creatinine excretion was higher in the control group than in the ipriflavone group, as compared to no difference at baseline. Five patients taking ipriflavone and five taking placebo experienced gastrointestinal discomfort or other adverse reactions, but only one and four subjects, respectively, had to discontinue the study. CONCLUSIONS Ipriflavone prevents the rapid bone loss following early menopause. This effect is associated with a reduction of bone turnover rate.

Abstract
To define which noninvasive investigations are of value in predicting bone histology, we analyzed transiliac bone specimens (66 biopsies, 14 autopsies) from 80 uremic patients on chronic dialysis. Results were compared with values of different measurements of parathyroid hormone (PTH), alkaline phosphatase (APH), osteocalcin, calcitonin, baseline and post-deferroxamine (DFO) aluminium (Al),--beta 2 microglobulin, ferritin and bone mineral density. Among histomorphometric parameters, woven osteoid, active osteoblastic surface and resorption surface showed the best correlations with dynamic and biochemical marks of active bone metabolism. Among biochemical parameters, intact PTH and APH were better related to histomorphometric and dynamic bone parameters than other PTH measurements as well as osteocalcin, while calcitonin was related to no parameters. Stainable Al alone, and not total bone Al content was related to bone histology. Baseline Al was related to lamellar osteoid, while post-DFO Al was related to stainable Al. beta 2 microglobulin was positively related to active osteoid surface and ferritin was inversely related to the mineral apposition rate, while bone mineral density was related only to total bone volume. We conclude that, though definite diagnosis requires the use of histological methods, few simple biochemical parameters may offer insight to the bone metabolic status, useful to the physician in day to day clinical practice.

Abstract
Osteopenia is a recognised complication of cholestatic liver diseases (CLD), usually ascribed to metabolic bone diseases such as osteomalacia or osteoporosis, with a prevalence from 10 to 56%, depending on the nature of liver disease. Primary biliary cirrhosis (PBC) is the condition causing osteopenia more frequently, but other cholestatic liver diseases like primary sclerosing cholangitis (PSC), haemochromatosis and alcoholic liver disease are also frequently associated with this disorder. The pathogenesis of bone disease in both adults and children with chronic cholestasis is not completely understood. There has been considerable disagreement regarding the relative importance of osteomalacia versus osteoporosis as the factors leading to osteopenia of liver disease. Osteopenia predisposes to atraumatic fractures, particularly in PBC patients undergoing orthotopic liver transplantation and treated with high corticosteroid doses. Bone mineral density measurement is the best way to assess the presence and severity of osteopenia in CLD patients, while laboratory tests give important information about the metabolic status of the bone. In this review prevalence data, diagnostic tools, pathophysiology and treatment of osteopenia in CLD are discussed.

Abstract
One hundred ninety-eight postmenopausal women (aged 50-65 years) with vertebral bone density (VBD) 1 SD below the mean value for normal, age-matched, postmenopausal subjects were enrolled in six Italian centers and 134 completed 2 years of treatment. All subjects were randomly allocated to a 2-year treatment with oral ipriflavone (200 mg t.i.d.) or a matching placebo, according to a double-blind, parallel group design. All patients also received an oral daily calcium supplement of 1 g as calcium carbonate. VBD and markers of bone turnover were measured at baseline, and every 6 months. A complete routine analysis of liver and kidney functions along with hematological parameters were measured before and at the end of treatment period. The valid completers analysis showed a significant increase of VBD in ipriflavone-treated women with average percent changes of +1.4 after 1 year, and +1% at the end of treatment period (P < 0.05). The placebo group presented a significant decrease of VBD after 2 years of treatment (P < 0.05). The difference between treatments was significant (P < 0.01). The intention to treat analysis confirmed the significant decrease of VBD in the placebo group, with no changes in ipriflavone-treated women. Skeletal ALP significantly decreased in ipriflavone-treated women (P < 0.05). Serum BGP and urine HOP/Cr showed a significant decrease only in ipriflavone-treated women, suggesting an inhibitory effect on bone turnover rate. Adverse reactions, mainly gastrointestinal, occurred to a similar extent in the two treatment groups. The evaluation of patients' compliance, assessed by residual tablets count, revealed a drug intake of more than 80% after 2 years in 92.5% and 92.8% of patients treated with ipriflavone or placebo, respectively. This study demonstrates that ipriflavone can prevent bone loss in postmenopausal women with low bone mass.

Abstract
We performed a cross-sectional study in 147 women, 41 in premenopausal age and 106 in menopause for 1-5 years: bone mineral density (BMD) at the distal radius and annual bone loss (as shown by plasma alkaline phosphatase and osteocalcin levels, and by calcium/creatinine and hydroxyproline/creatinine in the second urine of the morning) were evaluated. A significant reduction of BMD with a significant increase of bone loss was observed with increasing duration of menopause. Furthermore, when the women were subdivided into two groups according to annual bone loss (over or under 1.7%), significant differences were found between bone mineral density in the second and third years of menopause. As this is a cross-sectional and not a longitudinal study, it confirms that, in the presence of a higher bone loss, the BMD levels are lower and consequently the theoretical definition of this parameter can allow useful information on the presumable behavior of BMD.

Abstract
Bone mineral content (BMC) and testosterone levels were evaluated and compared in 10 hypogonadal males and 10 normal, age-matched controls. In 6 of the subjects an investigation was also carried out into the effects of testosterone administration on lumbar BMC, calcitonin (CT) response to hypercalcaemia, osteocalcin (BGP) and the fasting urinary calcium/creatinine and hydroxyproline/creatinine ratios. Our results confirm that male hypogonadism is characterized by a low BMC and that testosterone administration is able to improve this parameter and to increase both basal BGP and CT response to hypercalcaemia. Testosterone therefore probably acts on bone tissue through both a direct action on osteoblast cells and an improvement in CT secretion.

Abstract
It now appears to be accepted that oestrogens and progestogens can help to prevent post-menopausal bone loss. This study accordingly evaluated vertebral bone mineral content (BMC) patterns and changes in calcitonin (CT) secretion in 12 women who had been ovariectomized in the previous 6 mth and in 12 others who had had a natural menopause, all of whom received oestrogen-progestogen replacement therapy for 12 mth. We also studied 12 oophorectomized and 21 normal-menopause women who did not receive any treatment and hence constituted the corresponding control groups. A significant difference was found between the lumbar BMC in the treated women and the controls. Moreover, the CT levels rose significantly after replacement therapy in both the oophorectomized and the natural-menopause subjects. It was concluded that combined oestrogen-progestogen treatment can prevent post-menopausal bone loss and increase CT secretion.

Abstract
A case of unilateral linear basal cell nevus, diffuse osteoma cutis, unilateral anodontia, and abnormal bone mineralization is reported. Unlike the anodontia, the unilateral linear basal cell nevus and osteoma cutis began to appear in adulthood. A hamartomatous process is suggested to explain these conditions. This complex syndrome has not been reported in the literature.

Abstract
Three evaluations of lumbar bone mineral content (BMC) were carried out at different times at intervals of a few days in 10 normal volunteers aged between 18 and 60. The dual photon absorptiometry technique was employed (using gadolinium-153 as radioactive isotope). Data on 20 subjects aged from 23 to 62 were recorded on magnetic tape and processed ten times by the same operator. The data for individual subjects proved satisfactorily reproducible and the repeated processing of a single scan by the same investigator gave very satisfactory results. The findings demonstrate that the evaluation of lumbar BMC by dual photon absorptiometry can provide highly reproducible and acceptably accurate data.

Abstract
Double photon absorptiometry comparison was done of lumbar bone mineral content (BMC) values in 40 women with well-compensated non-insulin-dependent diabetes mellitus (type II) and on dietary and/or oral hypoglycemic treatment, and 35 age-matched non-diabetic women, to determine the presence and degree of osteoporosis in this type of diabetes by means of a highly precise and sensitive method. No difference between the two groups was noted as regards blood calcium, phosphorus, PTH and thyrocalcitonin, and urinary calcium and phosphorus. BMC, on the other hand, was significantly lower in the diabetics, both in L2,L3,L4 and in L4 alone. No significant difference could be discerned between patients on diet and those on drugs. It can thus be maintained that osteoporosis is a possible complication of type II diabetes and may appear even in the absence of its classical complications.

Abstract
Study was conducted on the multiplication of two strains (C243 and D) of parainfluenza virus type 3 in BHK 21 cells. Multiplication curve of the virus was established and immunohistochemical aspects of the process were investigated. Chronological study of successive steps of the formation and development of viral components allowed to see that the virus multiplication rate is low in this cell system. The parainfluenza antigen became detectable by immunofluorescence in the infected cell perinuclear region after a relatively long eclipse period (18 h) and synthetized virus has few RNA and induced no inclusion information in the cytoplasm or the nucleus. However, an important nuclear participation was noted: 72 h after inoculation, nuclear fluorescence was observed, as well as a nuclear DNA rising and frequent aberrant mitoses. Comparison between the two investigated strains led to the observation that the autochthonous D strain induced more frequent aberrant mitoses and more important cell destruction than the C243 one. Differences were also noted as regards the infecting and hemagglutinating titers.

Abstract
The NIVGRIP inactivated influenza vaccine was administered by oral route to 11 children of a semi-closed pre-school community, found to carry viruses in their nasopharynx. Periodic virological investigations demonstrated that after vaccination virus carriage disappeared completely in 7 children; in the remaining 4 cases there was a considerable decrease (from 14 to 6) in the number of virus strains isolated. The virus isolates obtained after vaccination were represented exclusively by enteroviruses (Coxsackie B1 and B3, poliovirus type 1), in contrast with the wider range of viral agents (adeno-, parainfluenza, herpes, Coxsackie, and polioviruses) detected prior to vaccine administration.
