ABSTRACT
UNLABELLED: Modifiable and non-modifiable predictors of mobility recovery were analyzed on a sample of 774 hip fracture patients according to pre-fracture abilities. Overall predictors were mostly non-modifiable factors related to frailty of patients with the exception of 25-hydroxyvitamin D concentration which significantly affected walking recovery, especially in patients with higher pre-fracture performance. INTRODUCTION: This study aims to investigate mobility changes after hip fracture with the aim of identifying modifiable and non-modifiable predictors of mobility recovery according to different pre-fracture abilities. METHODS: This is a prospective inception cohort study of consecutive older patients, admitted with a fragility hip fracture in three Hospitals of Emilia Romagna (Italy). A sample of 774 patients alive at the sixth month was divided into three groups according to pre-fracture ambulation ability (group 1: mobile outdoors; group 2: mobile indoors; and group 3: mobile with help). The relationship between baseline characteristics of patients and the odds of walking recovery was analyzed using multivariate regression analysis. RESULTS: Mortality differed significantly among the three groups and was the highest in patients needing help to walk. Among the survivors, only 50.3 % of patients recovered walking ability. In a multivariate analysis, independent risk factors were different among the three groups. In group 1, older age, comorbidities, the use of walking devices before fracture, and low albumin level acted as negative factors while male gender, a pre-fracture high functional status, and higher 25-hydroxyvitamin D levels increased the probability of full recovery. In group 2, only pre-fracture functional status and 25-hydroxyvitamin D concentration were related to the recovery of walking ability. Pre-fracture functional status was also the only significant predictor for patients in group 3. CONCLUSIONS: Several baseline characteristics of patients are related to the likelihood of recovering walking ability after hip fracture. The 25-hydroxyvitamin D level seems to be the only relevant modifiable factor even if the effectiveness of its supplementation has yet to be demonstrated.

IGF-1 decline has been related to age-dependent cognitive impairment and dementia. No study examined IGF-1 levels in subjects with a risk factor for brain damage such as hypertension. We investigated the relationship between IGF-1, cognitive functioning and neuroimaging in a sample of 75 hypertensive elderly subjects aged > 65. Cognitive performance were tested by mini mental state examination (MMSE), Cambridge cognitive examination (CAMDEX-R), and the frontal assessment battery (FAB). Among other indices, free IGF-1 in serum was assayed. The radial width of the temporal horn (rWTH) evaluates medial cerebral temporal lobe atrophy. Significant correlations between IGF-1 levels and both total and sub-domain scores of cognition were found. IGF-1 level was significantly lower in cognitively declined group. The lowest IGF-1 -percentile subgroup was significantly cognitively impaired. A statistically non-significant, but lower IGF-1 level was found in the sub-sample with pathologically wider rWTH. Levels of IGF-1 below 79.4 microg/l are associated with cognitive decline, whereas a level above 118 microg/l seems to be a marker of normal cognitive performance. A decreasing of IGF-1 related to a widening of the rWTH suggests an involvement of this hormone in hippocampus atrophy.

Hypertension is a risk factor for a long-lasting arterial wall-remodelling leading to stiffness. The rapid method measuring the pulse pressure (PP) by means of the tool of Hypertension Diagnostic Instruments (HDI) called PP-HDI, overcomes some of the problems arising with more-time consuming methods, like ambulatory blood pressure monitoring (ABPM), and give information about the elasticity of the arterial walls. We studied the relationship between the PP-HDI, the large artery compliance (LA-C) and small artery compliance (SA-C) and few well-established indices of arterial blood pressure (ABP) in a sample of 75 hypertensive subjects, aged 65 years and over. Significant correlations between LA-C and heart rate (HR), PP-ABPM and PP-HDI were found. SA-C relates with HR and systolic blood pressure (SBP) measured in lying and standing positions. Applying a stepwise regression analysis, we found that LA-C variance stems from PP-HDI and HR, while SA-C variance stems from SBP in lying position. Receiver operator characteristic (ROC) curves for thresholds of PP showed that PP-HDI reached levels of sensitivity/specificity similar to PP-ABPM. In conclusion, surveillance of ABP through hemo-dynamic indices, in particular of SBP, is essential, nevertheless the advantage of this control is not known in an elderly population where the organ damage is already evident. PP needs necessarily an instrumental measurement. The PP-HDI result is similar in reliability with respect to PPABPM, but is more rapid and well applicable in an elderly population.

The use of atypical antipsychotics (AA) is suggested in the treatment of BPSD, although controversial data are available on their safety and efficacy. The aim of this study was to assess the efficacy and safety of AA and whether this therapy could modify cognitive and functional domains in parallel with BPSD modifications. Out of 1,100 patients followed by the psychogeriatric ambulatory of our hospital, 69 patients (6.2%) were in therapy with AA and only 32 of them fulfilled the inclusion criteria of this study. Namely, the availability was required of a complete geriatric assessment, including the evaluation of cognitive (mini mental state examination=MMSE), emotional (the Italian "scala di valutazione del benessere emotivo nell'anziano"=SVEBA), functional (basic and instrumental activities of daily living=ADL and IADL), as well as behavioral (neuropsychological inventory=NPI) status, at the beginning (T(0)) and after a 6 month therapy (T(1)). The AA prescribed were risperidone (42.8%), olanzapine (31.3%), quetiapine (25.9%). The mean age was 80.1 years; 34.4% male; 65.6% female. Educational level was elementary in 90.6% of cases. Only 21.9% were institutionalized. 15.6% had 1 cardiovascular risk factor (CVRF), 50% more than 1, and the remaining with no CVRF. More than the half of them were diagnosed with degenerative dementia (D) (40.6% Alzheimer D=AD; 15.6% fronto-temporal dementia (FTD); 34.4% with vascular dementia (VD) (9.4%) or combined D (25%); 3,1 % with mild cognitive impairment (MCI), classified as F06.7 by the ICD-10 (International Classification of Diseases) and 6.2% with psychiatric disturbances. The most common BPSD were hallucinations, delusions, agitation, verbal and physical aggression. A paired t-test was applied to analyze data. There was a significant improvement with all 3 AA on NPI (mean NPI T(0)=27.50 vs. T(1)=12.13; t=7.49). An improvement was also observed on SVEBA (t=1.97), close to significance. Most people did not have any adverse effects; 5 patients (15.6%) had extrapyramidal symptoms and 1 (3.1%) showed ginecomasty, clinically so relevant to cause the interruption of the treatment. The profile of safety and efficacy described on the whole sample was confirmed when it was subdivided according to kind of drug, illness severity and presence/absence of CVRF. In a large sample of the "real" subjects attending a geriatric service for dementia, the accurate selection of patients treatable with AA leads to identification of a population with a negligible rate of adverse effects in presence of a high rate of efficacy with respect not only to BPSD but also to cognitive and functional domains.

There is bulk of evidence suggesting that blood pressure dysregulation, as low blood pressure (LBP) or hypotension, orthostatic hypotension (OH) and high blood pressure (HPB) or hypertension are associated with alterations in cognitive and emotional domains. Some studies suggest that LBP, neurocardiovascular instability, like the OH, and atherosclerosis resulting from long standing HBP, reduces cerebral blood flow, increasing the risk of cognitive impairment, morbidity and mortality. This study aims to evaluate whether patients with cognitive impairment and cardiovascular disease would show any differences in some anamnestic indicators and/or psychometric measures of cognitive performance and affective symptoms. We recruited 36 patients over 65 years of age admitted to both psycho- and cardio-geriatric ambulatories of our hospital during the last year. The population (mean age of 80.5 years, 72.2% females, 27.8% males) was divided in 2 groups, with OH (25%), and without OH (75%). The first group was subdivided in subgroups: patients with HBP, normal BP and LBP, respectively. Cognitive and depressive domains were assessed with the mini mental state examination (MMSE) and the Italian "scala di valutazione del benessere emotivo nell' anziano" (SVEBA). Information about the present status, comorbidities (cumulative illness rating scale=CIRS), functional ability (activities of daily living=ADL, instrumental ADL=IADL) and drugs were collected during clinical examination. BP was measured 4 times, at the beginning of examination, then with the patient in clinostatic and orthostatic position (1st and 3rd minute). Data were analyzed by MANCOVA, considering age and gender as covariates, MMSE, SVEBA, CIRS, ADL, IADL and drugs as dependent variables, and presence/absence of OH as factor. Covariates were not significant sources of variance, as well as overall factor. Due to the heuristic aim of the study, we considered of interest the results of subsequent ANOVAs showing significant differences in SVEBA and ADL with respect to the factor. These data give us the basis to develop a longitudinal study to confirm the detrimental effect of OH on a wide range of health domains.

BACKGROUND: Thalidomide, an anti-angiogenic agent, does not have a good therapeutic effect for advanced hepatocellular carcinoma when used alone. Megestrol and interleukin-2 have been proposed as a palliative treatment for hepatocellular carcinoma. AIMS.: We assessed the effectiveness/safety of a combined therapy with thalidomide+megestrol+interleukin-2 in cirrhotic patients with advanced hepatocellular carcinoma. PATIENTS AND METHODS: Nine cirrhotic patients with advanced hepatocellular carcinoma received oral megestrol (160 mg/day) and thalidomide (from 50 mg/day to the maximal tolerated dose). Four patients also received subcutaneous interleukin-2 (1 million U/day for 21 days/month). RESULTS: The maximal tolerated dose of thalidomide was 150 mg/day. All patients complained of sedation and other neurological or digestive adverse effects. In all but one patient the adverse effects disappeared after thalidomide withdrawal or dose reduction. Interleukin-2 administration caused a flu-like syndrome and a reaction at the injection site. During treatment, alpha-fetoprotein increased in six patients, remained stable in two and decreased in one. Eight patients showed tumour progression and one had a stable disease. Eight patients died. The median survival was 9.9 (range 2.6-18.6) months. CONCLUSION: In cirrhotic patients, the combined treatment with thalidomide+megestrol (+/-interleukin-2) does not control hepatocellular carcinoma growth, possibly due to the low tolerance to thalidomide and interleukin-2 preventing the use of appropriate dosages.

We report a case of Aspergillus arthritis of the shoulder in a renal transplant recipient. Cultures of three joint fluid specimens grew Aspergillus fumigatus. Itraconazole as sole treatment resulted in initial clinical and roentgenographic improvements but failed to prevent deterioration in joint function. A relapse with fatal neurologic involvement occurred. Immune deficiency-inducing risk factors for aspergillosis include neutropenia and corticosteroid therapy. Previously published cases of Aspergillus arthritis of limb joints are reviewed. The advantages and limitations of itraconazole as single drug therapy are outlined.
