RESUMO

This study aimed to minimize the number of times cattle need to be confined during protocols for TAI in beef cows treated for induction of ovulation with EB at the time of P4 device removal (P4r). In Experiment 1, cows were treated with P4 plus EB (Day 0; AM) and were allocated to one of three groups at P4r: EB8.5, EB at P4r on Day 8.5 (PM; three confinements); EB9, EB 24 h after P4r on Day 8 (AM; four confinements) and EC8, EC at P4r on Day 8 (AM; positive control; three confinements). At P4r, cows were treated with PGF2a plus eCG. Ultrasonography was performed from D8 to D12. The interval from P4r to ovulation was less in the EB8.5 compared to EB9 and EC8 group. There was no difference in the ovulation rate between groups. The variability of ovulation was greater in the EB8.5 and EC8 compared to EB9 group. In Experiment 2, cows of EC8 and EB9 groups were submitted to TAI 48 to 52 h (AM) or 54 to 58 h (PM) after P4r (D10). Cows of the EB8.5 group were submitted to TAI 38 to 42 h (AM) or 44 to 48 h (PM) after P4r (D10). There was no interaction between treatments and timing of AI and no treatment effect and timing of AI on P/AI. In conclusion, the delay compared to what typically occurs by 10 h of P4r concomitant with EB administration (Day 8.5) reduced the frequency of animal confinement for the TAI protocol without affecting the reproductive efficiency and the flexibility to perform the TAI in suckled beef cows.

RESUMO

The Multidimensional Geriatric Assessment (MGA) is currently used for assessing geriatric oncological patients, but a new prognostic index - the Multidimensional Prognostic Index (MPI) - has a demonstrated prognostic value in cancer patients too. The present work was designed to compare the MPI and MGA as predictors of 12-month mortality. 160 patients ≥70 years old with locally-advanced or metastatic solid cancers consecutively joining our Geriatric Oncology Program were administered a Comprehensive Geriatric Assessment to calculate their MGA and MPI scores. SETTINGS: Geriatric Clinic, Geriatric Surgery Clinic, Medical Oncology Unit, Padova Hospital, Italy. Using Cohen's Kappa coefficient, there was a poor concordance between the MPI and MGA. Severe MPI being associated with a higher mortality risk than Frail in the MGA. The ROC curves indicated that the MPI had a greater discriminatory power for 12-month mortality than the MGA. In our population of elderly cancer patients, the MPI performed better than the MGA in predicting mortality. Further evidence from larger prospective trials is needed to establish whether other geriatric scales, such as the GDS and CIRS-SI, could enhance the value of prognostic indexes applied to elderly cancer patients.

RESUMO

The role of genetic molecular markers in neoadjuvant treatment for locally advanced esophageal cancer has been reviewed, focusing strictly on concurrent chemoradiation protocols followed by surgery. Eleven studies evaluated the role of mRNA expression profile; the end point was overall survival (OS) in two studies and different definitions of histological response in nine. Genes reported as significant were involved in cell cycle control (30), apoptosis (7), structural molecules (9), cell metabolism (6) and DNA repair (1). Seven studies reported about 15 microRNA (miRNA) molecules associated with OS (2) or histological response (13), however, defined with different classifications. Their target genes were prevalently involved in cell cycle control (4), apoptosis (1), cell adhesion (1), migration (1) and angiogenesis (1). Gene polymorphisms (single-nucleotide polymorphisms (SNPs)) have been evaluated in 8 studies reporting 10 variants associated with survival or pathological response. OS was the end point in six of these studies. SNPs reported as significant were involved in DNA repair system (4), detoxification (2), folate metabolism (6), drug efflux (2) and others (2). In a study, a panel including histology, pathological response and five SNPs discriminated two subsets of patients with 5-year survival rates of 79.3% and 26.3% (hazard ratio 6.25, P<0.0001). In another study, combination of stage, grade and 4 miRNAs improved prediction of pathological response (P=10-30). At present, given the great inconsistency of the data and the variability of the end points, definite conclusions are extremely difficult, if not impossible. More consistent data can derive only from analyses obtained from patients included in prospective randomized trials while panels combining genetic and clinical factors may improve prediction.

RESUMO

OBJECTIVE: The aim of this study was to evaluate adherence to the Mediterranean Diet (MD) and its association with all-cause mortality in an elderly Italian population. DESIGN: Data analysis of a longitudinal study of a representative, age stratified, population sample. SETTING: Study data is based upon the Italian Longitudinal Study on Aging (ILSA) a prospective, community-based cohort study. The baseline evaluation was carried out in 1992 and the follow-up in 1996 and 2000. PARTICIPANT: Participant food intake assessment was available at baseline for 4,232 subjects; information on survival was available for 2,665 at the 2000 follow-up. MEASUREMENTS: Adherence to the MD was evaluated with an a priori score based on the Mediterranean pyramid components. Cox proportional hazard models were used to assess the relationship between the MD score and all-cause mortality. Six hundred and sixty five subjects had died at the second follow-up (identified up to the first and second follow-up together; mean follow-up: 7.1±2.6 years). RESULTS: At the 2000 follow-up, adjusting for other confounding factors, participants with a high adherence to MD (highest tertile of the MD score distribution) had an all-cause mortality risk that was of 34% lower with respect to the subjects with low adherence (Hazard Ratio=0.66; 95% CI: 0.49-0.90; p=0.0144). CONCLUSION: According to study results, a higher adherence to the MD was associated with a low all-cause mortality risk in an elderly Italian population.

RESUMO

Candidate genes involved in DNA repair, 5-fluorouracil metabolism and drug detoxification were genotyped in 124 patients receiving neoadjuvant chemoradiation treatment for locally advanced esophageal cancer and their predictive role for long-term relapse-free survival (RFS) and cancer-specific survival (CSS) were evaluated. A panel including MTHFR 677TT, MDR1 2677GT, GSTP1 114CC, XPC 499CC and XPC 939AC+CC, defined as high-risk genotypes, discriminated subgroups with significantly different outcomes. When the panel was combined with histology, patients split into two subsets with 5-year RFS and CSS rates of 65% vs 27% (hazard ratio (HR) 3.0, P<0.0001) and 69% vs 31% (HR 2.9, P<0.0001), respectively. Combining the 5-single-nucleotide polymorphism (5-SNP) panel with pathological response defined two major informative risk classes with 5-year PFS and CSS rates of 79.4% vs 17.7% (HR 6.71, P<0.0001) and 79.3% vs 26.3% (HR 6.25, P<0.0001), respectively. This classification achieved a sensitivity of 79%, a specificity of 85.4% and an accuracy of 81.8%.

RESUMO

BACKGROUND AND AIMS: Serum uric acid (SUA) is the end-product of purine metabolism in humans, and its levels often increase in subjects with metabolic syndrome (MetS). Despite several studies demonstrating a relationship between increased SUA levels and the prevalence of MetS, prospective data on SUA as a predictor of the incidence of MetS in the elderly are limited. Our aim was to conduct a prospective study on the association between SUA concentrations and the onset of MetS in an elderly Italian cohort. METHODS AND RESULTS: This is a cohort study (Progetto Veneto Anziani; Pro.V.A.) involving community-dwelling subjects aged ≥65 years and followed up for a mean 4.4 years. We included 1128 participants (aged 74.7 ± 7.1 years) without MetS at the baseline. Gender-specific SUA groups according to the standard deviation (SD) from the mean were considered, taking the incidence of MetS as the main outcome. The mean SUA level was significantly higher in men than in women (5.4 ± 1.2 vs. 4.5 ± 1.2 mg/dl; p < 0.0001). Over the 4.4-year follow-up, 496 individuals developed MetS. After adjusting for potential confounders, Cox's regression analysis revealed no relationship between higher baseline SUA concentrations and the incidence of MetS in men or in the sample as whole, while women with SUA levels more than 1 SD above the mean (≥5.7 mg/dl) carried a 58% higher risk (95%CI: 1.03-2.40; p = 0.03) of being newly diagnosed with MetS during the follow-up. CONCLUSION: High SUA levels significantly and independently predicted MetS in older women, but not in men, over a 4.4-year follow-up.

RESUMO

Four experiments were designed to evaluate the effect of different circulating progesterone (P4) concentrations during a synchronization of ovulation protocol for the timed artificial insemination (TAI) of Bos indicus (Nelore) beef cattle. In the first trial, 13 ovariectomized Nelore heifers were randomly allocated into one of three groups using new P4 devices (New; 1.0 g P4), previously used P4 devices for 8 days (Used1x), and previously used P4 devices for 16 days (Used2x), in a crossover experimental design. The circulating P4 concentrations during the P4 device treatment were lower for Used1x (2.3 ± 0.1 ng/mL) and Used2x (2.0 ± 0.1 ng/mL) than those for New (3.8 ± 0.2 ng/mL; P = 0.001). In the second trial, the ovarian follicular dynamics of 60 anestrous cows were evaluated after the cows received the treatments described previously (New [n = 20], Used1x [n = 20], and Used2x [n = 20]). During the insertion of the P4 device, the cows were administered 2.0-mg estradiol benzoate. Eight days later, the P4 device was removed, and the cows were administered 0.53-mg sodium cloprostenol, 300 IU eCG, and 1-mg estradiol cypionate. There were no differences among the groups during the interval from P4 device removal to ovulation (73.7 ± 2.9 vs. 69.8 ± 2.4 vs. 68.4 ± 2.3 hours) or regarding the ovulation rate (70.0% vs. 80.0% vs. 85.0%). However, the maximum diameter of the largest follicle was greater (P = 0.06) in the Used2x (15.3 ± 0.4 mm) than that of New (13.5 ± 0.8 mm) and Used1x (14.9 ± 0.5 mm). In experiment 3, 443 anestrous cows were randomly assigned into one of the three treatments (New [n = 144] vs. Used1x [n = 167] vs. Used2x [n = 132]) and received a TAI 48 hours after the P4 device removal. The diameter of the largest follicle during the device removal (10.7 ± 0.3 vs. 11.2 ± 0.2 vs. 11.3 ± 0.3 mm) and the 30-day pregnancy rates (51.4% vs. 53.9% vs. 43.2%) did not differ among the experimental groups. In experiment 4, a field trial with 593 B indicus (Nelore) cows was conducted to evaluate the pregnancy per AI using different levels of P4 in a TAI protocol (New [n = 189] vs. Used1x [n = 203] vs. Used2x [n = 201]). The pregnancy per AI was similar between the treatment groups (63.5% vs. 57.6% vs. 62.7%). In conclusion, the low circulating P4 concentrations that were released from a used P4 device efficiently controlled the ovarian follicular growth and exhibited no detrimental effects on the pregnancy rates of the B indicus (Nelore) beef cattle.

RESUMO

Immunoglobulin G4-related disease (IgG4-RD) is a newly recognized fibroinflammatory condition which can potentially involve any organ. Some characteristic histopathologic features with lymphoplasmacytic infiltrate, an increased number of IgG4+ cells, storiform fibrosis and obliterative phlebitis are the mainstay for diagnosis. Serum IgG4 levels often increase. We report the case of a patient with perivascular fibrotic lesions involving the aortic arch and the splenic hilum, with a surgical biopsy-proven diagnosis of IgG4-related disease. The patient is now undergoing a low-dose corticosteroid maintenance therapy without evidence of new localizations of the disease. This case highlights the need for increasing awareness and recognition of this new, emerging clinical condition.

RESUMO

AIM: To assess the predictive value of fluorine-18-fluorodeoxyglucose ((18)F-FDG) positron emission tomography/computed tomography (PET/CT) in early assessing response during neo-adjuvant chemoradiotherapy (CRT) in patients with locally advanced rectal cancer. MATERIALS AND METHODS: A systematic review was performed by search of MEDLINE Library for the following terms: "rectal carcinoma OR rectal cancer", "predictive OR prediction OR response assessment OR response OR assessment", "early OR ad interim", "therapy", "FDG OR (18)F-FDG", "PET OR PET/CT". Articles performed by the use of stand-alone PET scanners were excluded. RESULTS: 10 studies met the inclusion criteria, including 302 patients. PET/CT demonstrated a good early predictive value in the global cohort (mean sensitivity = 79%; mean specificity = 78%). SUV and its percentage decrease (response index = RI) were calculated in all studies. A higher accuracy was demonstrated for RI (mean sensitivity = 82%; pooled specificity = 85%) with a mean cut-off of 42%. The mean time point to perform PET scan during CRT resulted to be at 1.85 weeks. Some PET parameters resulted to be both predictive and not statistical predictive of response, maybe due to the small population and few studies bias. CONCLUSION: PET showed high accuracy in early prediction response during preoperative CRT, increased with the use of RI as parameter. In the era of tailored treatment, the precocious assessment of non-responder patients allows modification of the subsequent strategy especially the timing and the type of surgical approach.

RESUMO

AIM: This study assessed the prevalence of depressive symptomatology (DS) in older individuals with diabetes to determine whether diabetes and DS are independent predictors of mortality, and if their coexistence is associated with an increased mortality risk. METHODS: Analyses were based on data from the Italian Longitudinal Study on Aging (ILSA), a prospective community-based cohort study in which 5632 individuals aged 65-84years were enrolled. The role of diabetes and DS in all-cause mortality was evaluated using the Cox model, adjusted for possible confounders, for four groups: 1) those with neither diabetes nor DS (reference group); 2) those with DS but without diabetes; 3) those with diabetes but no DS; and 4) those with both diabetes and DS. RESULTS: Type 2 diabetes mellitus (T2DM) was present in 13.8% of the participants; they presented with higher baseline rates of DS compared with the non-diabetic controls. During the first follow-up period, participants with DS but not diabetes had a 42% higher risk of all-cause mortality compared with the reference control group (HR=1.42; 95% CI: 1.02-1.96), while participants with diabetes but not DS had an 83% higher risk of death than the reference group (HR=1.83; 95% CI: 1.19-2.80). The risk of death for those with both disorders was more than twice that for the reference group (HR=2.58; 95% CI: 1.55-4.29). Analyses of deaths from baseline to the second follow-up substantially confirmed these results. CONCLUSION: The prevalence rate of DS is higher in elderly people with diabetes and their coexistence is associated with an increased mortality risk.

RESUMO

AIM: To identify the characteristics associated with multidimensional impairment, evaluated through the Multidimensional Prognostic Index (MPI), a validated predictive tool for mortality derived from a standardized Comprehensive Geriatric Assessment (CGA), in a cohort of elderly diabetic patients treated with oral hypoglycemic drugs. METHODS AND RESULTS: The study population consisted of 1342 diabetic patients consecutively enrolled in 57 diabetes centers distributed throughout Italy, within the Metabolic Study. Inclusion criteria were diagnosis of type 2 diabetes mellitus (DM), 65 years old or over, and treatment with oral antidiabetic medications. Data concerning DM duration, medications for DM taken during the 3-month period before inclusion in the study, number of hypoglycemic events, and complications of DM were collected. Multidimensional impairment was assessed using the MPI evaluating functional, cognitive, and nutritional status; risk of pressure sores; comorbidity; number of drugs taken; and cohabitation status. The mean age of participants was 73.3 ± 5.5 years, and the mean MPI score was 0.22 ± 0.13. Multivariate analysis showed that advanced age, female gender, hypoglycemic events, and hospitalization for glycemic decompensation were independently associated with a worse MPI score. CONCLUSION: Stratification of elderly diabetic patients using the MPI might help to identify those patients at highest risk who need better-tailored treatment.

RESUMO

AIM: The objective of the METABOLIC Study was to evaluate overall health status, with particular focus on assessment of functional status of older patients taking oral antidiabetic drug (OAD) treatment. METHODS: The study included 1342 type 2 diabetes patients aged ≥ 65 years treated with OADs, with or without insulin, who had been referred to outpatients clinics across Italy. Information on diabetes (duration, medications taken during the last 3 months, hypoglycaemic events and diabetic complications) was collected by questionnaire, and the patients' overall health status was assessed using a multidimensional prognostic index. RESULTS: The sample recruited (mean age: 73.3 ± 5.5 years) had a mean duration of diabetes of 11.3 ± 8.2 years. Half were taking sulphonylureas alone or together with other medications, 9.7% were taking insulin in combination with other OADs, almost 30% were using biguanides and 6.2% were taking dipeptidyl peptidase-4 (DPP-4) inhibitors. Also, 12% of patients reported hypoglycaemic events, 90% of whom were taking insulin or sulphonylureas. In addition, 81% of the participants were completely independent in their activities of daily living, while 19% were mildly, moderately or severely disabled. Age, female gender, hypoglycaemic events, neuropathy and low diastolic blood pressure were the main variables associated with disability. CONCLUSION: Disability is common in older diabetic patients and some associated factors, such as hypoglycaemia and low diastolic blood pressure, have been identified. Also identified was malnutrition as a specific factor associated with hypoglycaemic events independent of the use of insulin and sulphonylureas.

RESUMO

UNLABELLED: This study aimed to evaluate the prevalence of vertebral fractures in elderly women with a recent hip fracture. The burden of vertebral fractures expressed by the Spinal Deformity Index (SDI) is more strictly associated with the trochanteric than the cervical localization of hip fracture and may influence short-term functional outcomes. INTRODUCTION: This study aimed to determine the prevalence and severity of vertebral fractures in elderly women with recent hip fracture and to assess whether the burden of vertebral fractures may be differently associated with trochanteric hip fractures with respect to cervical hip fractures. METHODS: We studied 689 Italian women aged 60 years or over with a recent low trauma hip fracture and for whom an adequate X-ray evaluation of spine was available. All radiographs were examined centrally for the presence of any vertebral deformities and radiological morphometry was performed. The SDI, which integrates both the number and the severity of fractures, was also calculated. RESULTS: Prevalent vertebral fractures were present in 55.7% of subjects and 95 women (13.7%) had at least one severe fracture. The women with trochanteric hip fracture showed higher SDI and higher prevalence of diabetes with respect to those with cervical hip fracture, p=0.017 and p=0.001, respectively. SDI, surgical menopause, family history of fragility fracture, and type2 diabetes mellitus were independently associated with the risk of trochanteric hip fracture. Moreover, a higher SDI was associated with a higher percentage of post-surgery complications (p=0.05) and slower recovery (p<0.05). CONCLUSIONS: Our study suggests that the burden of prevalent vertebral fractures is more strictly associated with the trochanteric than the cervical localisation of hip fracture and that elevated values of SDI negatively influence short term functional outcomes in women with hip fracture.

RESUMO

BACKGROUND AND AIMS: Three groups of subjects were identified within a representative sample of older Italians: subjects with normal fasting glucose (NFG), with impaired fasting glucose (IFG) or with type 2 diabetes mellitus (T2D). The aim of the present study was to evaluate the relationship among plasma lipids, lipoproteins, other metabolic factors in the three groups, and their role in predicting total fatal events. METHODS AND RESULTS: 2422 subjects, aged 65-84 years, taking part into the Italian Longitudinal Study on Aging were included in the analyses. Factor analysis was conducted separately for men and women. Factor scores were used as independent variables in Cox Proportional Hazard models, to determine factors predicting death at the follow-up in NFG, IFG and T2D subjects. Four major factors were found for men ("insulin resistance", "body size", "total cholesterol", "HDL cholesterol") and four also for women ("insulin resistance", "total cholesterol", "body size", "HDL cholesterol"). For NFG and IFG men, and for both T2D men and women, the "HDL cholesterol" was a significant protective factor for total deaths (NFG men: HR = 0.79, 95% CI 0.67-0.93; IFG men: HR = 0.59, 95% CI 0.45-0.79; T2D men: HR = 0.55, 95% CI 0.34-0.89; T2D women: HR = 0.61, 95% CI 0.44-0.86). Among NFG women, the "body size" factor was also a protective factor with respect to total deaths (HR = 0.74, 95% CI 0.57-0.95). CONCLUSION: A factor including HDL Cholesterol and Apo A-I showed protection against all-cause mortality in older men, independently from the glycemia level, and in women only in those diagnosed with T2D.

RESUMO

OBJECTIVE: The aim of the present study was to identify women at high risk of having osteoporosis according to the clinical judgment of their General Practitioners, but without a previous diagnosis of osteoporosis. DESIGN: Cross-sectional survey. PARTICIPANTS: The General Practitioners were asked to select a sample of women aged 65 years or more who could be affected by osteoporosis but had never been diagnosed nor treated: this sample included 8,268. Moreover, 8,956 women asked to be included in the study on a voluntary basis, and were analyzed separately. MEASUREMENTS: Participants were referred to a mobile unit equipped with GE Lunar Express Ultras (Achilles), where they were administered a questionnaire and underwent a QUS examination. They were classified at high, moderate or low risk of having osteoporosis according to the 2007 International Society for Clinical Densitometry official position. RESULTS: The prevalence rate of women at high risk of having osteoporosis was 12.5%; 53% were considered at moderate risk. Logistic regressions revealed that age, early age at menopause, history of fractures, dysthyroidism and smoking were associated with high and moderate risk. CONCLUSIONS: Results suggest that General Practitioners are able to identify women at risk of having osteoporosis, but often do not treat them, suggesting that osteoporosis in Italy is still a neglected condition. The strength of the association of risk factors is similar in women at high and medium risk: this may raise a debate on the validity of this classification in the Italian population.

RESUMO

In rheumatic diseases, biomarkers may serve as surrogate endpoints for diagnosis, prognosis, disease activity, therapeutic response and disease outcome. In recent years a great effort has been made to identify useful tools to establish early diagnosis, prognosis and therapeutic response especially in rheumatoid arthritis (RA). In psoriatic arthritis (PsA) serological biomarkers have been frequently borrowed from RA, but this approach have sometimes lead to inappropriate choices of biomarkers and incorrect conclusions. Furthermore, the heterogeneous spectrum of articular manifestation of PsA and the variable course of the disease can make diagnosis and prognosis difficult. Recently, the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) identified two key areas for biomarkers development in psoriasis and PsA: the diagnosis of the articular disease in patients with psoriasis and the evaluation of joint damage in PsA. In this review we revised the currently available and the new potential markers for PsA, such as serum, genetic, cellular and histological biomarkers, clinical and imaging data, with particular attention on the prognostic aspect in order to identify progressive disease suitable for a more aggressive treatment.

RESUMO

The effects of estradiol benzoate (EB) and estradiol cypionate (EC) on induction of ovulation after a synchronized LH surge and on fertility of Bos indicus females submitted to timed AI (TAI) were evaluated. In Experiment 1, ovariectomized Nelore heifers were used to evaluate the effect of EB (n = 5) and EC (n = 5) on the circulating LH profile. The LH surge timing (19.6 and 50.5 h; P = 0.001), magnitude (20.5 and 9.4 ng/mL; P = 0.005), duration (8.6 and 16.5 h; P = 0.001), and area under the LH curve (158.6 and 339.4 ng/mL; P = 0.01) differed between the EB and EC treatments, respectively. In Experiment 2 (follicular responses; n = 60) and 3 (pregnancy per AI; P/AI; n = 953) suckled Bos indicus beef cows submitted to an estradiol/progesterone-based synchronization protocol were assigned to receive one of two treatments to induce synchronized ovulation: 1 mg of EB im 24 h after progesterone (P4) device removal or 1 mg of EC im at P4 device removal. There was no difference (P > 0.05) between EB and EC treatments on follicular responses (maximum diameter of the ovulatory follicle, 13.1 vs. 13.9 mm; interval from progesterone device removal to ovulation, 70.2 vs. 68.5 h; and ovulation rate, 77.8 vs. 82.8%, respectively). In addition, P/AI was similar (P < 0.22) between the cows treated with EB (57.5%; 277/482) and EC (61.8%; 291/471). In conclusion, despite pharmacologic differences, both esters of estradiol administered either at P4 device removal (EC) or 24 h later (EB) were effective in inducing an LH surge which resulted in synchronized ovulations and similar P/AI in suckled Bos indicus beef cows submitted to TAI.

RESUMO

UNLABELLED: A score for identifying post-hip-fracture surgery patients at various levels (high, medium, and low) of risk for unsuccessful recovery of pre-fracture walking ability was developed. Three hundred ninety-eight HF patients were enrolled in the study. The score significantly and independently predicted failure to walk independently at discharge, failure to walk independently after 12 months, and death after 12 months. The score may be useful for clinicians and healthcare administrators to target populations for rehabilitative programs. INTRODUCTION: To develop a model predicting at the time that elderly hip-fracture (HF) patients undergo rehabilitation if they will have recovered walking independence at discharge. METHODS: Data from all patients admitted to a Department of Rehabilitation in Italy between January 2001 and June 2008 after HF surgery were used. Variables concerning cognitive, clinical, functional, and social parameters were evaluated. Predominant measures were identified through correspondence analysis, and a variable score was defined. Three risk classes (minimum, moderate, and high) were identified and univariate and multivariate logistic regressions were used to assess the model's predictivity and risk classes for the various outcomes. RESULTS: Three hundred ninety-eight HF patients were enrolled. The variables selected to construct the score were age, gender, body mass index, number of drugs being taken, the Mini Mental State Examination, the Instrumental Activity of Daily Living, and the pre-fracture Barthel index. According to univariate analysis, the score was not better than the pre-fracture Barthel's index, but, according to multivariate analysis, it was an independent predictor for all the outcomes, while the pre-fracture Barthel index predicted only outcomes at discharge. In particular, the score significantly predicted failure to walk independently at discharge, failure to walk independently after 12 months, and death after 12 months. CONCLUSIONS: A method of identifying post-HF surgery patients at various levels (high-, medium-, and low-) of risk for unsuccessful recovery of pre-fracture walking ability has been designed. The method may be useful for clinicians and healthcare administrators to target populations for rehabilitative programs.

RESUMO

AIM: To investigate whether or not the metabolic syndrome (MetS) can predict the incidence of diabetes and all-cause mortality among elderly subjects. METHODS: Analyses were based on data collected by the Italian Longitudinal Study on Aging (ILSA) that, between 1992 and 1996, enrolled 5632 participants aged 65 to 84 years. The analyses included 3081 participants for whom complete data were available. Logistic-regression models were designed to study the influence of the MetS on the incidence of diabetes, adjusting for individual MetS components and possible confounders. Data on mortality collected between baseline and the 1996 follow-up were also considered, and Cox's proportional hazards models were used to determine the death risk attributable to the synergistic relationship between the MetS and diabetes. RESULTS: The MetS was strongly associated with an increased risk of diabetes (OR: 5.53, 95% CI: 2.89-10.60). After adjusting for its individual components and possible confounders, the MetS maintained an important role in predicting the incidence of diabetes (OR: 2.65, 95% CI: 0.97-7.24) together with the fasting glucose component (OR: 5.89, 95% CI: 2.89-11.98). Over the 4-year follow-up, participants with diabetes, but without the MetS, and subjects with the MetS, but without diabetes, had no significant risk of death compared with the reference group. Elderly subjects who had both the MetS and diabetes had almost double the risk of death vs the reference group (HR: 1.80, 95% CI: 1.04-3.12). CONCLUSION: The MetS is associated with the incidence of diabetes, and the synergy between the MetS and diabetes is an important risk factor for all-cause mortality in elderly subjects.
