The role of the Sunfrail tool in the screening of frailty and in integrated community-hospital care pathways: a retrospective observational study.

BACKGROUND: One of the most problematic expression of ageing is frailty, and an approach based on its early identification is mandatory. The Sunfrail-tool (ST), a 9-item questionnaire, is a promising instrument for screening frailty. AIMS: To assess the diagnostic accuracy and the construct validity between the ST and a Comprehensive Geriatric Assessment (CGA), composed by six tests representative of the bio-psycho-social model of frailty; To verify the discriminating power of five key-questions of the ST; To investigate the role of the ST in a clinical-pathway of falls' prevention. METHODS: In this retrospective study, we enrolled 235 patients from the Frailty-Multimorbidity Lab of the University-Hospital of Parma. The STs' answers were obtained from the patient's clinical information. A patient was considered frail if at least one of the CGAs' tests resulted positive. RESULTS: The ST was associated with the CGA's judgement with an Area Under the Curve of 0.691 (CI 95%: 0.591-0.791). Each CGA's test was associated with the ST total score. The five key-question showed a potential discriminating power in the CGA's tests of the corresponding domains. The fall-related question of the ST was significantly associated with the Short Physical Performance Battery total score (OR: 0.839, CI 95%: 0.766-0.918), a proxy of the risk of falling. DISCUSSION: The results suggest that the ST can capture the complexity of frailty. The ST showed a good discriminating power, and it can guide a second-level assessment to key frailty domains and/or clinical pathways. CONCLUSIONS: The ST is a valid and easy-to-use instrument for the screening of frailty.

A Longitudinal Study on Cognitive Training for Cognitively Preserved Adults in Liguria, Italy.

In this study, we examined the effects of memory training on cognitive function and depressive symptoms in a cohort of 794 healthy adults aged 50 years or older. Participants were divided into an active intervention group and a passive intervention group, with various cognitive measures assessed over a one-year period. Univariate analysis revealed that the active intervention group consistently outperformed the passive group in measures of memory self-perception (Memory Complaint Questionnaire-MACQ), depressive symptoms (Geriatric Depression Scale-GDS-4), verbal memory and recall ability (A3LP), and verbal fluency (VF). Significant differences in MACQ scores were observed between the two groups at all time points, indicating enhanced memory self-perception in the active group. GDS-4 scores consistently favored the active group, suggesting a reduction in depressive symptoms. A3LP scores demonstrated that the active group had better verbal memory and recall abilities. VF scores consistently favored the active group, indicating superior language skills and cognitive flexibility. Linear regression model and mixed linear regression model reinforced these findings, with highly significant interaction effects observed between the active/passive group, gender, age, education, and time. These effects were particularly pronounced for MACQ and A3LP scores, indicating the combined impact of these factors on memory self-perception and verbal memory. This study highlights the positive impact of memory training intervention on cognitive function and depressive symptoms in older adults and underscores the importance of considering gender, age, and education in cognitive interventions. Notably, these benefits persist for up to six months from the end of the program. The results provide valuable insights into cognitive changes in aging populations and suggest that tailored memory training programs can yield significant improvements.

Digital Health Service for Identification of Frailty Risk Factors in Community-Dwelling Older Adults: The SUNFRAIL+ Study Protocol.

This article reports the study protocol of a nationwide multicentric study in seven Italian regions aimed at assessing the effectiveness of a digitally supported approach for the early screening of frailty risk factors in community-dwelling older adults. SUNFRAIL+ is a prospective observational cohort study aimed at carrying out a multidimensional assessment of community-dwelling older adults through an IT platform, which allows to connect the items of the SUNFRAIL frailty assessment tool with a cascading multidimensional in-depth assessment of the bio-psycho-social domains of frailty. Seven centers in seven Italian regions will administer the SUNFRAIL questionnaire to 100 older adults. According to the answers provided by older adults, they will be subjected to one or more validated in-depth scale tests in order to perform further diagnostic or dimensional evaluations. The study aims to contribute to the implementation and validation of a multiprofessional and multistakeholder service model for the screening of frailty in community-dwelling older adult population.

Neridronate improves bone mineral density and reduces back pain in ß-thalassaemia patients with osteoporosis: results from a phase 2, randomized, parallel-arm, open-label study.

Neridronate is a third generation bisphosphonate with established efficacy in metabolic bone disease. In this randomized, open-label study, 118 adults with ß-thalassaemia and bone mineral density (BMD) Z scores ≤-2·0 were randomized 1:1-500 mg calcium with 400 international unis (iu) vitamin D daily or 500 mg calcium with 400 iu vitamin D daily plus neridronate 100 mg intravenously every 90 d. Significant increases in BMD at the lumbar spine and total hip were noted in the neridronate group at 6 and 12 months from baseline (P < 0·001), and values were significantly higher than the control group at both time intervals. Neridronate also significantly decreased serum bone alkaline phosphatase and C-telopeptide of collagen type 1 levels from as early as 3 months (P = 0·04 and P < 0·001, respectively), reaching significantly lower values at 12 months compared with the control group (P < 0·05). Reductions in back pain and analgesic use were also evident, starting 3 months from commencing treatment. Treatment was well tolerated by all patients. In this largest randomized trial in thalassaemia-induced osteoporosis to date, neridronate was safe and effective in reducing bone resorption and increasing BMD. The associated reduction in back pain and improved quality of life will encourage adherence to therapy. (Clinicaltrials.gov identifier NCT01140321.).

Alendronate and indapamide alone or in combination in the management of hypercalciuria associated with osteoporosis: a randomized controlled trial of two drugs and three treatments.

BACKGROUND: The role of bisphosphonates (BPs) in the management of patients with hypercalciuria (HC) associated with osteoporosis is still uncertain. The aim of the study was to evaluate the effect of alendronate and indapamide alone or in combination on bone mineral density (BMD) and 24-h urinary calcium excretion (24-CaU) in post-menopausal women with HC and low BMD. METHODS: A total of 77 post-menopausal women with HC (24-CaU > 4 mg/kg/day) and low BMD [T-score < -2.0 at lumbar spine (LS), femoral neck (FN) or total hip (TH)] from two centres of Northern Italy were randomized to receive indapamide 2.5 mg daily alone (24 patients, IND group), alendronate 70 mg weekly alone (27 patients, ALN group) or the combination therapy (26 patients, ALN + IND group). Throughout the study, all subjects received daily calcium supplements, depending on their dietary intake, to maintain a daily input of 1000 mg. Patients were instructed to increase water intake up to 2000 mL daily. The percentage and absolute changes of BMD at LS, FN and TH, and the variation of 24-CaU from baseline at 1 year were the primary outcomes. Serum calcium, phosphate, parathyroid hormone and bone alkaline phosphatase were also measured. RESULTS: Overall 67 women completed the study and were included in the final analysis. Patients in the three groups were similar with regard to baseline characteristics. BMD did not significantly change from baseline after 1 year of treatment with indapamide (LS: +1 +/- 3.1%; FN: -0.3 +/- 3.5%; TH: -0.4 +/- 3.1%), while it showed a significant increase from baseline in the other two groups (ALN; LS: +5.8 +/- 4.2%, P < 0.001; FN: +3.9 +/- 7.9%, P = 0.018; TH: +2 +/- 3.6%, P = 0.006) (ALN + IND; LS: +8.2 +/- 5.3%, P < 0.001; FN: +4.9 +/- 6.7%, P = 0.007; TH: +2.9 +/- 4.2%, P = 0.004). Patients in the combination group showed a significantly higher increase of BMD at LS compared to ALN (P = 0.04). After 1 year, 24-CaU values significantly decreased from baseline in all groups (IND, 239 +/- 78 versus 364 +/- 44, P < 0.001) (ALN, 279 +/- 68 versus 379 +/- 79, P < 0.001) (ALN + IND, 191 +/- 68 versus 390 +/- 55, P < 0.001). The mean percentage decrease of 24-CaU in ALN + IND group (-50%) was significantly greater compared to ALN (-24%, P < 0.001) and IND (-35%, P = 0.012). CONCLUSIONS: These results show a benefit, in terms of BMD improvement and 24-CaU reduction, associated with BPs' therapy in combination with indapamide in HC associated with osteoporosis. The combination therapy demonstrated a reduction of 24-CaU and an increase in LS BMD superior to that observed with alendronate alone. Our results support a new potential approach with BPs associated with thiazide diuretics or indapamide in the management of post-menopausal women with HC and associated bone loss. Studies on the larger sample size are needed to demonstrate the efficacy on the fracture outcome.

Factors associated with an immediate weight-bearing and early ambulation program for older adults after hip fracture repair.

OBJECTIVE: To evaluate baseline characteristics and in-hospital factors associated with nonadherence with an immediate weight-bearing and early ambulation (IWB-EA) program after hip fracture (HF) surgery. DESIGN: Prospective inception cohort study. SETTING: Ortho-geriatric unit in an acute care hospital. PARTICIPANTS: Older adults (N=469) admitted with an osteoporotic HF who underwent surgery. INTERVENTIONS: Immediate weight-bearing and assisted ambulation training on the first postoperative day (all patients). MAIN OUTCOME MEASURE: Proportion of subjects who adhered to the IWB-EA protocol within 48 hours of surgery. RESULTS: A total of 366 patients (78%) bore weight and ambulated within 48 hours (weight-bearing [WB] group) while the others did not adhere to the protocol (nonweight-bearing [NWB] group). Subjects in the NWB group were significantly older, were more cognitively and functionally impaired, and presented a higher comorbidity at baseline. A higher proportion of subjects in the NWB group (42.7%) than the WB group (23.5%; P<.001) underwent surgery on a preholiday day. In multivariate analysis, having surgery on Friday or a preholiday day (the day before a public holiday) remained the most influent variable related to nonadherence to the IWB-EA protocol (odds ratio=2.5; 95% confidence interval=1.6-4.0; P<.001). CONCLUSIONS: This study establishes that IWB-EA is feasible in a high proportion of patients after surgical stabilization of HF. Neither cognitive impairment nor high comorbidity influenced significantly the adherence to the protocol, indicating that IWB-EA may be offered to an unselected population of the elderly with HF. The day of surgery (eg, preholiday or not) was the only variable influencing the participation to the IWB-EA protocol, suggesting the importance of maintaining the same standard of daytime care every day of the week.

Intramuscular neridronate in postmenopausal women with low bone mineral density.

Compliance to osteoporosis treatment with oral bisphosphonates is very poor. Intermittent intravenous bisphosphonate is a useful alternative, but this route is not readily available. Neridronate, a nitrogen-containing bisphosphonate that can be given intramuscularly (IM), was tested in a phase 2 clinical trial in 188 postmenopausal osteoporotic women randomized to IM treatment with 25 mg neridronate every 2 weeks, neridronate 12.5 or 25 mg every 4 weeks, or placebo. All patients received calcium and vitamin D supplements. The patients were treated over 12 months with 2-year posttreatment follow-up. After 12-month treatment, all three doses were associated with significant bone mineral density (BMD) increases at both the total hip and spine. A significant dose-response relationship over the three doses was observed for the BMD changes at the total hip but not at the spine. Bone alkaline phosphatase decreased significantly by 40-55% in neridronate-treated patients, with an insignificant dose-response relationship. Serum type I collagen C-telopeptide decreased by 58-79%, with a significant dose-response relationship (P < 0.05). Two years after treatment discontinuation, BMD declined by 1-2% in each dose group, with values still significantly higher than baseline at both the spine and the total hip. Bone turnover markers progressively increased after treatment discontinuation, and on the second year of follow-up the values were significantly higher than pretreatment baseline. The results of this study indicate that IM neridronate might be of value for patients intolerant to oral bisphosphonates and unwilling or unable to undergo intravenous infusion of bisphosphonates.

Secondary hyperparathyroidism due to hypovitaminosis D affects bone mineral density response to alendronate in elderly women with osteoporosis: a randomized controlled trial.

OBJECTIVES: To determine whether secondary hyperparathyroidism (HPTH) due to hypovitaminosis D affects bone mineral density (BMD) response to alendronate (ALN) in elderly women with osteoporosis. DESIGN: Randomized, controlled trial with 1-year follow-up. SETTING: Two osteoporosis centers in northern Italy. PARTICIPANTS: Community-dwelling women aged 60 and older with a BMD T-score below -2.5 and secondary HPTH with vitamin D insufficiency. INTERVENTION: One hundred twenty subjects were randomly assigned to receive ALN 70 mg once a week alone or ALN 70 mg once a week plus calcitriol (1,25D3) 0.5 microg daily. MEASUREMENTS: BMD measured using dual-energy x-ray absorptiometry at the lumbar spine (L1-L4), femoral neck, and total hip and serum levels of intact PTH at baseline and 12 months. RESULTS: After 1 year, BMD of the lumbar spine, femoral neck, and total hip significantly increased from baseline in both groups (P<.001). Patients allocated to ALN plus 1,25D3 demonstrated a significantly higher increase in lumbar spine BMD than those receiving ALN alone (mean percentage+/-standard deviation 6.8+/-4.6 vs 3.7+/-3.2, P<.001). Serum levels of PTH did not change significantly at 1 year in the ALN group (mean percentage, -3.7+/-27.1, P=.13) but decreased significantly in the ALN plus 1,25D3 group (-32.1+/-22.1, P<.001). At 12 months, subjects with normalized PTH independent of therapy allocation had a greater increase in lumbar spine BMD than those with persistent HPTH (6.5+/-4.6% vs 3.7+/-3.4%, P<.001). Lumbar spine BMD changes showed a significant negative correlation with PTH at 1 year (correlation coefficient (rho) =-0.399, P<.001) and a positive correlation with PTH changes (i.e., baseline value - 1 year value; rho=0.295, P=.005). CONCLUSION: Persistence of secondary HPTH reduces BMD response to ALN in older women with osteoporosis.

The Italian reference sites of the European innovation partnership on active and healthy ageing: Progetto Mattone Internazionale as an enabling factor.

BACKGROUND: Ageing population implies an increasing demand for health care services and resources, unsustainable according to current previsions. The European Commission is tackling this challenge throughout initiatives such as the European Innovation Partnership on Active and Healthy Ageing (EIP-AHA), where all the efforts are aligned to the common goal of adding two active and healthy years to the life of European Union (EU) citizens. METHOD: We presented the collaborative efforts of Italian Reference Site Collaborative Network 2012-2015. RESULTS: Italian regions joined forces through the "Progetto Mattone Internazionale" of the Ministry of Health developing several national and international collaborations. Activities from all five Italian reference sites are presented with different good practices and scale-up approaches for improving health in ageing population. DISCUSSION: The simultaneous development of these activities allowed the strengthening of the coordination of Italian stakeholders in the European arena fostering collaboration and supporting the streamlining of the Italian regions still outside these projects.

[Relationship between 25-hydroxy vitamin D and cognitive status in older adults: the COGNIDAGE study]. / Livelli di 25(OH)D e performance cognitive in una popolazione di anziani: lo studio COGNIDAGE.

AIM: The aim of the COGNIDAGE study was to examine the association between 25(OH)D and cognitive status in a group of elderly patients with vitamin D deficiency and high burden of comorbidities attending Geriatric Outpatient Clinics. MATERIALS AND METHODS: We studied the relationship between 25(OH)D and cognitive functions taking into account comorbidities and cognitive functions assessed by MMSE (Mini Mental State Examination), CDT (Clock Drawing Test) and CIRS (Cumulative Illness Rating Scale), in 132 consecutive elderly patients with low levels of 25(OH)D (<10 ng/ml) compatible with the condition of vitamin deficiency. The association among 25(OH)D levels, MMSE score, CDT score and CIRS scores were analyzed using Pearson correlation. All the elderly patients received an adequate vitamin D supplementation and were reassessed after 6 months. RESULTS: At baseline, mean MMSE and CIRS scores were: 21.8+5.56 and 2.96 +1.63 respectively. Mean CDT score was 3,66+-2.05. No associations were found between 25(OH)D levels and global cognitive function. A significant relationship was observed between the total CIRS score and 25(OH)D levels (r=0.305; p=0.000) as well as between total CIRS score and MMSE (r=-0.375; p=0.000). After 6 months, 83.9 % had 25(OH)D levels >20 ng/ml. Mean MMSE and CDT scores were 22.20+-5.76 and 3.90+-2.06 respectively. There was no significant correlation among 25(OH)D, MMSE and CDT scores while a significant correlation was found between 25(OH)D and CIRS- severity score (r=0.275; p=0.001) and between MMSE and total CIRS scores (r=-0.247; p=0.005 for CIRS-comorbidities; r=-0.184; p=0.04 for CIRS-severity). A post hoc evaluation on two subgroups of elderly patients (the first with vitamin D deficiency without cognitive impairment, the second with vitamin D deficiency and dementia) showed a statistically significant difference (p=0.00001) regarding the CIRS-comorbidities scores. CONCLUSIONS: In our cohort of elderly patients with a high burden of comorbidities, 25(OH)D low levels (<10 ng/ml) are not associated with MMSE and CDT scores. There is no statistically difference among the levels of 25(OH)D and MMSE and CDT scores after 6 months. The strong correlation we found regarding CIRS-comorbidities in the two sub-groups suggests that vitamin D deficiency may play a role in promoting cognitive impairment only with comorbidities.

Bisphosphonates in the management of idiopathic hypercalciuria associated with osteoporosis: a new trick from an old drug.

Idiopathic hypercalciuria (IHC) is defined as a 24-hour urinary calcium excretion that exceeds 4 mg/kg/day, regardless of gender and in absence of systemic diseases or pharmacological treatments that may cause normocalcemic hypercalciuria (eg sarcoidosis, normocalcemic primary hyperparathyroidism, vitamin D intoxication, hyperthyroidism). Patients with IHC and nephrolithiasis often present increased bone turnover, decreased bone mineral density (BMD) and increased susceptibility to fragility fractures. Although the pathogenesis of IHC seems complex and multifactorial, recent evidences suggest that cells involved in bone resorption may play a critical role in the chain of events leading to the excessive urinary calcium excretion. Therefore, it has been proposed that bisphosphonates, potent inhibitors of bone resorption, may have beneficial effects in hypercalciuric patients with low BMD. This manuscript reports recent findings regarding the role of bone tissue in the pathogenesis of IHC, and supports the use of bisphosphonates in such conditions. It also reviews the literature on the effects of bisphosphonates in subjects with osteoporosis-associated IHC.

Heterogeneity in serum 25-hydroxy-vitamin D response to cholecalciferol in elderly women with secondary hyperparathyroidism and vitamin D deficiency.

OBJECTIVES: To compare the effects on parathyroid hormone (PTH) and 25-hydroxy-vitamin D (25(OH)D) of two dosing regimens of cholecalciferol in women with secondary hyperparathyroidism (sHPTH) and hypovitaminosis D and to investigate variables affecting 25(OH)D response to cholecalciferol. DESIGN: Randomized-controlled trial with 6-month follow-up. SETTING: Two osteoporosis centers in northern Italy. PARTICIPANTS: Sixty community-dwelling women aged 65 and older with sHPTH and hypovitaminosis D, creatinine clearance greater than 65 mL/min and without diseases or drugs known to influence bone and vitamin D metabolism. INTERVENTION: Cholecalciferol 300,000 IU every 3 months, once at baseline and once at 3 months (intermittent D(3) group) or cholecalciferol 1,000 IU/day (daily D(3) group). MEASUREMENTS: Serum PTH, 25(OH)D, calcium, bone-specific alkaline phosphatase, ß-C-terminal telopeptide of type I collagen, phosphate, 24-hour urinary calcium excretion. RESULTS: The two groups had similar baseline characteristics. All participants had vitamin D deficiency [25(OH)D<20 ng/mL)], and 36 subjects (60%) had severe deficiency (<10 ng/mL), with no difference between the groups (severe deficiency: intermittent D(3) group, n=18; daily D(3) group, n=18). After 3 and 6 months, both groups had a significant increase in 25(OH)D and a reduction in PTH. Mean absolute increase ± standard deviation of 25(OH)D at 6 months was higher in the intermittent D(3) group (22.7±11.8 ng/mL) than in the daily D(3) group (13.7±6.7 ng/mL, P<.001), with a higher proportion of participants in the intermittent D(3) group reaching desirable serum concentration of 25(OH)D≥30 ng/mL (55% in the intermittent D(3) group vs 20% in the daily D(3) group, P<.001). Mean percentage decrease of PTH in the two groups was comparable, and at 6 months, a similar proportion of participants reached normal PTH values. 25(OH)D response to cholecalciferol showed a wide variability. In a logistic regression analysis, body mass index and type of treatment appeared to be significantly associated with normalization of 25(OH)D values. CONCLUSION: Cholecalciferol 300,000 IU every 3 months was more effective than 1,000 IU daily in correcting vitamin D deficiency, although the two groups achieved similar effects on PTH at 6 months. Only 55% of the higher-dose intermittent group reached desirable concentrations of 25(OH)D, suggesting that yet-higher doses will be required for adequate vitamin D repletion.

Persistence with calcium and vitamin D in elderly patients after hip fracture.

All hip fracture (HF) subjects are candidates for calcium and vitamin D (CaD) supplementation. Up to 50% of HF older adults present with secondary hyperparathyroidism (HPTH) resulting from hypovitaminosis D on hospital admission. To investigate the patterns and predictors of persistence with CaD supplementation in the elderly after HF, we considered all patients aged 70 years or older who were discharged alive after surgical repair of HF in the period of 1 year from an Orthopaedic Unit. Baseline characteristics of the subjects and osteoporosis treatment prescribed at discharge were retrieved from medical record review. A telephone interview at 6 months evaluated whether patients were currently taking CaD supplementation. Nonpersistence was defined when subjects ceased therapy within 6 months. Univariate and multivariate models were applied to determine the relationship between 6 months persistence with CaD and the variables collected: age, living situation, prescription of a bisphosphonate, baseline walking ability, number of drugs used, presence of dementia, number of active clinical issues at discharge (ACIs), discharge location, and being referred to a center for metabolic bone diseases (preplanned visit) at discharge. Of 428 subjects enrolled, 117 were excluded for different reasons (incomplete data, no therapy, death). A total of 311 subjects were discharged with a prescription of CaD (calcium 1,000 mg, cholecalciferol 800 UI, once daily) and were considered for the analysis. At 6 months, only 114 patients (36.7%) were currently taking CaD supplementation. In a univariate analysis, the following variables were significantly related with persistence: absence of dementia, prescription of a bisphosphonate, six or fewer drugs being used (drugs used

General and specific mortality among the elderly during the 2003 heat wave in Genoa (Italy).

The effects of heat waves on health can be serious for elderly persons, especially those in urban areas. We investigated in-depth the mortality excess during the 2003 heat wave among elderly persons (>74 years) in the City of Genoa (Italy). The excess in general mortality was calculated for the period July 16-August 31, as the ratio of observed to expected deaths. To evaluate "harvesting", we compared observed and expected mortality in the period September 2003-April 2004. We also studied the relationship between mortality and climatic conditions considering daily maximum temperature and Humidex discomfort degrees, as well as "lag-time". For cause-specific mortality, we considered all pathologies reported on the death certificate. The excess in general mortality was significant and was greatest in the first half of August. During Summer 2003, in Genoa the climatic conditions (described in terms of maximum temperature and Humidex Index) were extremely hot; regarding lag-time, the greatest correlation between the number of observed deaths and the maximum temperature values was observed for the three preceding days (rho=0.568; significance level<0.01). The prominent causes of death, for which an excess was observed, were cerebrovascular diseases, severe respiratory diseases, severe renal diseases, dementia; moreover, certain pathologic conditions and symptoms, usually not lethal, were also frequent causes of death (e.g., hypovolemia, hyperpyrexia, decubitus ulcers and immobilization syndrome). The results of this study confirm the relationship between the heat waves and death among elderly, stressing that, because of their poorer physical health and the prevalence of cognitive disturbances that hinder risk perception, it is necessary to properly care for them during heat waves.

Clinically non-functioning pituitary macroadenomas in the elderly.

BACKGROUND AND AIMS: The aim of the present study was to evaluate the clinical presentation, characteristics and post-surgical outcome of non-functioning pituitary macroadenomas (NFPM) in elderly patients. METHODS: 27 patients (65-81 years; 13 Males, 14 Females) with NFPM (20-45 mm in diameter) were studied. The symptoms prompting neuroradiological studies were vision alterations in 52%, and dizziness, loss of memory, confusion, headache and depression in 29%; in 19% of patients, the disease was incidentally discovered during computed tomography (CT) or magnetic resonance imaging (MRI) for head trauma or cerebral ischemic attacks. RESULTS: Endocrinological evaluation on diagnosis showed global anterior hypopituitarism in 33% and partial hypopituitarism in 37% of patients. Immunohistochemistry showed signs of neurosecretion in most NFPM (chromogranin-A in 55%, gonadotropins in 19%, ACTH in 3.7%). Ki-67 antigen expression was indicative of low proliferative activity. Surgery was highly effective in improving alterations in vision and compressive symptoms, but was unable to restore normal pituitary function in established hypopituitarism in most cases. Eight patients (31%) were free of disease on subsequent MRI (follow-up 1-6 years). In 18 (69%) patients, a post-surgical residue was present. Of these, 6 (33%) underwent radiotherapy in the following years, owing to an increase in the volume of the remnants, and six (33%) underwent additional surgical treatment, followed by radiotherapy for further signs of growth in two. In the remaining patients, a small intrasellar remnant was stable on yearly MRI. CONCLUSIONS: in elderly patients, the development of hypopituitarism is often overlooked and the initial diagnosis of NFPM may be delayed. This can expose patients to the risks of unrecognized hypopituitarism and jeopardize post-surgical outcome.

Predictors of mortality after hip fracture: results from 1-year follow-up.

BACKGROUND AND AIMS: The study investigates one-year mortality risk associated with hip fracture in elderly people, and pre-fracture characteristics and events occurring during the acute phase which may represent significant predictors for acute and long-term mortality. METHODS: The study is a prospective cohort study of 252 patients aged 70 and older, consecutively admitted with hip fracture to the Division of Orthopedic Surgery of the Galliera Hospital of Genoa, Italy. At admission, each subject received a standardized diagnostic evaluation, including demographic variables, biochemical markers of nutritional status and basic medical, functional and cognitive assessment. Patients were followed by telephone interviews at three months, six months and one year after fracture. The relationship between mortality and the risk factors recorded was assessed using logistic regression models. RESULTS: 248 patients were eligible. Cumulative mortality was 4.8% during hospital stay, and 12.5% at 3, 18.9% at 6 and 24% at 12 months. The risk factors significantly associated with mortality were: sex, Acute Physiology Score (APS), comorbidity, functional and cognitive status, and albumin levels. In multivariate models, albumin below 3 g/dL remained the only significant predictor of in-hospital mortality (OR 6,8, 95% CI 1.56-29,7, p<0.001); functional status and comorbidity were significant risk factors of mortality after 6 and 12 months. CONCLUSIONS: These findings confirm the important role of serum albumin in assessing in-hospital health status and defining its role as a strong predictor of early and late mortality after hospital discharge. They also emphasize the effects of comorbidity and functional impairment on long-term mortality after hip fracture. Identifying these predictive factors may be helpful in improving case management during hospital stay and more accurate discharge planning.

An analysis of the feasibility of home rehabilitation among elderly people with proximal femoral fractures.

OBJECTIVE: To evaluate the feasibility and predictors of success of home-based rehabilitation (HBR) in older adults after hip fracture. DESIGN: Prospective inception cohort study with 12 months of follow-up. SETTING: Acute and subacute care with follow-up in a community setting in Italy. PARTICIPANTS: Community-dwelling older adults (N=199) aged 70 years or older, discharged from an acute orthopedic unit after repair of a nontraumatic proximal femoral fracture. INTERVENTIONS: Patients' choice of pursuing HBR or institutional-based rehabilitation (IBR). MAIN OUTCOME MEASURES: Proportion of subjects discharged home for rehabilitation. Rates of institutionalization assessed at 3, 6, and 12 months postdischarge. Mean changes of the Barthel Index from baseline and proportion of subjects who regained their prefracture levels of function at the time of follow-up in the 2 intervention groups (HBR, IBR). RESULTS: Ninety-nine (49.7%) patients chose HBR, and the rest (50.3%) were discharged to a rehabilitation facility. With regard to the baseline characteristics, the 2 patient groups (HBR, IBR) differed with respect to living arrangement (P< or =.001), prefracture functional status in basic (Barthel Index, P=.033; Katz Index, P=.041) and instrumental activities of daily living (IADLs) (P=.041), and occurrence of delirium (P=.022). During the follow-up, the number of subjects institutionalized at 3, 6, and 12 months was 52, 26, and 22, respectively. In the multiple logistic regression model, the only significant variable affecting the choice of IBR at discharge was the absence of relatives at home (odds ratio [OR], 6.7; 95% confidence interval [CI], 3.33-13.46; P< or =.001), whereas a prefracture functional impairment in more than 3 IADLs (at 12 mo: OR=3.99; 95% CI, 1.57-10.18; P=.004), the absence of relatives at home (at 12 mo: OR=8.81; 95% CI, 2.47-31.46; P=.001), and delay to surgery longer than 3 days (at 12 mo: OR=5.51; 95% CI, 1.28-23.81; P=.022) resulted in significant risk factors for long-term institutionalization. Compared with subjects who received traditional rehabilitation, those discharged home showed--after controlling for prefracture Barthel Index score, IADLs, cognitive status and age--a slightly lower functional decline and a higher rate of recovery during the follow-up (mean change in Barthel Index score +/- standard deviation at 12 mo: HBR, -11.2+/-24.7 vs IBR, -23.7+/-28.5; P=.015). CONCLUSIONS: In an unselected population of hip-fractured older adults previously living in the community, HBR seems to be a feasible alternative to IBR in those subjects living with relatives.

Primary hyperparathyroidism and neuropsychiatric alterations in a nonagenarian woman.

Whether elderly patients with asymptomatic or minimally symptomatic primary hyperparathyroidism (PHPT) should be treated or not is still under debate. Several literature reports have shown improvements in terms of bone density and physical and mental well-being after surgical resolution of PHPT. Here, we present the case of a 93-year-old hypertensive woman, who had suffered for one year from cognitive impairment, accompanied during the last month by behavioral alterations (and polyuria and polydipsia), which resulted in sopor leading to hospitalization. A CT brain scan evidenced cortical atrophy and cerebrovascular disease, and biochemical analyses were remarkable for hypercalcemia (11.4-12.6 mg/dL, corrected for albumin levels) associated with increased parathormone levels (95.4-100.6 pg/mL). A diagnosis of PHPT was established. Densitometry evaluation of radius showed osteopenia. Withdrawal of psycho-therapy drugs and thiazidic, together with i.v. saline hydration and loop diuretics, significantly improved the patient's mental state and resolved behavioral alterations. As the patient and her relatives refused the surgical option, and the clinical situation improved after medical normalization of calcium levels, PHPT was managed conservatively, and calcium levels were maintained within the normal range through i.v. administration of zoledronate at 8-week intervals. Our case highlights the importance of considering hypercalcemia as the cause of onset of behavioral alterations and worsening of mental condition in elderly patients with cognitive decline. Therapy with bisphosphonates in patients with PHPT who are unfit for or refuse surgery seems advisable, but needs further study.
