Abstract
In recent years, cognitive theories have increasingly influenced the approach to motor rehabilitation. The connection between different aspects of cognitive and motor function is increasingly documented, underlining the importance of developing rehabilitation projects that take cognitive aspects into account. The aim of this non-systematic review is to highlight the relationship between cognition and motion and, in the light of new rehabilitation technologies, to better define how aspects of cognition can affect motor rehabilitation.

Abstract
Even after rehabilitation, post stroke patients remain disabled. The Post Stroke Checklist (PSC) was developed to highlight unmet needs of community-dwelling stroke patients. The present study set out to validate Post Soft Care-App, designed to administer the PSC using smartphones and tablets, in order to monitor unmet needs in chronic patients. Fifty-three patients and fifteen physiotherapists were enrolled. The therapists administered the PSC to patients using the app, and then completed a structured questionnaire on its usability and utility. The Post Soft Care-App highlighted the following unmet needs: increased spasticity (56.6%), reduced independence in activities of daily living (47.2%), reduced mobility (45.3%), absence of secondary prevention (45.3%). Therapists positively evaluated Post Soft Care-App as useful, practical, quick to complete (96.2%), and effective in helping improve communication with patients (75.5%). The Post Soft Care-App can be considered a valid assessment tool for helping therapists to monitor functional outcomes in chronic patients.

Abstract
Muography is an imaging technique based on the measurement of absorption profiles for muons as they pass through rocks and earth. Muons are produced in the interactions of high-energy cosmic rays in the Earth’s atmosphere. The technique is conceptually similar to usual X-ray radiography, but with extended capabilities of investigating over much larger thicknesses of matter thanks to the penetrating power of high-energy muons. Over the centuries a complex system of cavities has been excavated in the yellow tuff of Mt. Echia, the site of the earliest settlement of the city of Naples in the 8th century BC. A new generation muon detector designed by us, was installed under a total rock overburden of about 40 metres. A 26 days pilot run provided about 14 millions of muon events. A comparison of the measured and expected muon fluxes improved the knowledge of the average rock density. The observation of known cavities proved the validity of the muographic technique. Hints on the existence of a so far unknown cavity was obtained. The success of the investigation reported here demonstrates the substantial progress of muography in underground imaging and is likely to open new avenues for its widespread utilisation.

Abstract
BACKGROUND Individuals with factor V Leiden or prothrombin G20210A mutations are at a higher risk to develop venous thromboembolism. However, the influence of these polymorphisms on patient outcome during anticoagulant therapy has not been consistently explored. METHODS We used the Registro Informatizado de Enfermedad TromboEmbólica database to compare rates of venous thromboembolism recurrence and bleeding events occurring during the anticoagulation course in factor V Leiden carriers, prothrombin mutation carriers, and noncarriers. RESULTS Between March 2001 and December 2015, 10,139 patients underwent thrombophilia testing. Of these, 1384 were factor V Leiden carriers, 1115 were prothrombin mutation carriers, and 7640 were noncarriers. During the anticoagulation course, 160 patients developed recurrent deep vein thrombosis and 94 patients developed pulmonary embolism (16 died); 154 patients had major bleeding (10 died), and 291 patients had nonmajor bleeding. On multivariable analysis, factor V Leiden carriers had a similar rate of venous thromboembolism recurrence (adjusted hazard ratio [HR], 1.16; 95% confidence interval [CI], 0.82-1.64), half the rate of major bleeding (adjusted HR, 0.50; 95% CI, 0.25-0.99) and a nonsignificantly lower rate of nonmajor bleeding (adjusted HR, 0.66; 95% CI, 0.43-1.01) than noncarriers. Prothrombin mutation carriers and noncarriers had a comparable rate of venous thromboembolism recurrence (adjusted HR, 1.00; 95% CI, 0.68-1.48), major bleeding (adjusted HR, 0.75; 95% CI, 0.42-1.34), and nonmajor bleeding events (adjusted HR, 1.10; 95% CI, 0.77-1.57). CONCLUSIONS During the anticoagulation course, factor V Leiden carriers had a similar risk for venous thromboembolism recurrence and half the risk for major bleeding compared with noncarriers. This finding may contribute to decision-making regarding anticoagulation duration in selected factor V Leiden carriers with venous thromboembolism.

Abstract
Cognitive deficits occur in most stroke patients and cognitive impairment is an important predictor of adverse long term outcome. However, current screening measures, such as the Mini Mental State Examination or the Montreal Cognitive Assessment, do not provide information tuned for evaluating the impact of cognitive impairment in the early phase after stroke. The Oxford Cognitive Screen (OCS) represents an important new development in this regard. The OCS is now available for assessment of Italian individuals and the aim of this study is to standardize the OCS on a large sample of healthy Italian participants stratified for age, gender and education level. Results confirmed the influence of these factors in several of the OCS tasks. Age-, education- and gender-adjusted norms are provided for the ten sub-tests of the test. The availability of normative data represents an important prerequite for the reliable use of OCS with stroke patients.

Abstract
BACKGROUND The recurrence of hepatitis C viral infection is common after liver transplant, and achieving a sustained virological response to antiviral treatment is desirable for reducing the risk of graft loss and improving patients' survival. AIM To investigate the long-term maintenance of sustained virological response in liver transplant recipients with hepatitis C recurrence. METHODS 436 Liver transplant recipients (74.1% genotype 1) who underwent combined antiviral therapy for hepatitis C recurrence were retrospectively evaluated. RESULTS The overall sustained virological response rate was 40% (173/436 patients), and the mean follow-up after liver transplantation was 11±3.5 years (range, 5-24). Patients with a sustained virological response demonstrated a 5-year survival rate of 97% and a 10-year survival rate of 93%; all but 6 (3%) patients remained hepatitis C virus RNA-negative during follow-up. Genotype non-1 (p=0.007), treatment duration >80% of the scheduled period (p=0.027), and early virological response (p=0.002), were associated with the maintenance of sustained virological response as indicated by univariate analysis. Early virological response was the only independent predictor of sustained virological response maintenance (p=0.008). CONCLUSIONS Sustained virological response achieved after combined antiviral treatment is maintained in liver transplant patients with recurrent hepatitis C and is associated with an excellent 5-year survival.

Abstract
A multicentre cross-sectional survey was performed to provide an accurate picture of patients with chronic hepatitis B (CHB) cared for by Italian Infectious Diseases Centers (IDCs). This analysis describes factors associated with access to the treatment of CHB in a country where barriers to treatment are not expected to exist because of comprehensive coverage under the National Health System (NHS). The study was performed in 74 IDCs. The analysis focused on 3305 patients with CHB of 3760 HBsAg-positive patients enrolled from March to September, 2008. To account for missing values, a Multiple Imputation method was used. Treatment was reported in 2091 (63.3%) patients. In the multivariate analysis, an increased chance of getting treatment was independently associated with 10 years increase of age at diagnosis (adjusted odds ratio [aOR] 1.2, 95% confidence interval [CI] 1.1-1.3, P < 0.001), HBeAg positivity (aOR 1.8, 95% CI 1.1-2.8, P < 0.001), cirrhosis (aOR 3.6, 95% CI 2-6.3, P = 0.012), HDV (aOR 1.6, 95% CI 1.02-2.5, P = 0.042) and HIV positivity (aOR 6.5, 95% CI 4-10.8, P < 0.001). Conversely, a decreased chance was associated with female gender (aOR 0.6, 95% CI 0.5-0.7, P < 0.001), immigration (aOR 0.6, 95% CI 0.5-0.9, P = 0.009), alcohol consumption (aOR 0.7, 95% CI 0.5-0.98, P = 0.04) and HCV positivity (aOR 0.5, 95% CI 0.3-0.8, P = 0.005). Our study shows that Italian IDCs treat a high percentage of patients with CHB. Nevertheless, disparities exist which are not related to the severity of disease limiting access to antiviral therapy of CHB, even in a country with a universal healthcare system.

Abstract
Giant cell hepatitis (GCH) has been rarely described in adult HIV patients, and its outcome remain unknown. We report two cases of GCH among 81 HIV patients co-infected with the hepatitis C virus (HCV). Both patients had a sustained virological response, suppression of HCV viral load and HIV viral suppression after highly active antiretroviral therapy. Our findings would suggest that the presence of giant cells does not influence the clinical course of hepatitis.

Abstract
BACKGROUND An evaluation of the prevalence of occult hepatitis B virus (HBV) infection in HIV-positive individuals is important as HBV infection may have an impact on the outcome of the liver disease in these patients. MATERIALS AND METHODS Of the 1,593 HIV-positive subjects enrolled in the Italian Cohort Naïve Antiretroviral (ICONA) program, 175 (10.9%) were selected for inclusion in the study on the basis of hepatitis B surface antigen (HBsAg) negativity and antibody to hepatitis B core antigen (anti- HBc) positivity; 101/175 (58%) were also anti-hepatitis C virus (HCV) positive. HBV-DNA was detected in plasma using a highly sensitive PCR assay (detection limit: 2.6 copies/ml). Two different genomic regions were assayed. Quantification was performed by real-time PCR. The HBV genotype was determined in 20 cases with occult HBV infection. Data on the antiretroviral therapy (ART) regimen was obtained in 169 individuals: 53 (31.4%) patients were ART-naive, 46 (27.2%) were under ART without lamivudine or tenofovir, and the remaining 70 (41.4%) were under ART including lamivudine or tenofovir. RESULTS 27/175 (15%) patients had detectable HBV-DNA in their plasma: 21/101 (21%) were anti-HCV positive and 6/74 (8%) were anti-HCV negative. Genotype D was invariably found in the 20 cases analyzed. Occult HBV infection was significantly higher in HCV-coinfected subjects: adjusted OR 5.02, 95% CI 1.31-19.26, p = 0.02. The value was not associated with immune status, HIV load, or ART regimen. CONCLUSIONS In relation to the high prevalence of occult HBV infection, particularly in HIV/HCV-coinfected individuals, it is necessary to clarify the clinical impact of this cryptic infection by monitoring HBV-DNA in plasma using the correct approach. Similarly to HBsAg-positive individuals of the Mediterranean area, HBV genotype D is invariably detected in this cohort of HIV-infected patients with occult HBV infection.

Abstract
Cryptococcus neoformans infections are typically associated with T-cell deficiencies, including acquired immunodeficiency syndrome (AIDS). Although highly active antiretroviral therapy (HAART) has strongly reduced AIDS-related opportunistic infections, the restoration and reactivation of CD4+ cells can induce an immune reconstitution inflammatory syndrome (IRIS), consisting in a deregulated inflammatory response to latent infectious pathogens and/or to their residual antigens. Cryptococcal lymphadenitis has occasionally been documented in IRIS. Here we report a case of histology- and culture-negative cryptococcal lymphadenitis associated with IRIS in an adult AIDS patient with a history of disseminated cryptococcosis, after the start of fully adherent HAART. Appropriate diagnosis was established on nested-PCR and sequence analysis of the interspacer region 2 of C. neoformans ribosomal DNA, and detection of slow-growing blastospores in enrichment cultures of fine-needle lymph node aspirate. Review of recent literature and our case findings suggest that IRIS-associated cryptococcal lymphadenitis is more likely the flare up of a latent infection rather than an immunopathological response to residual antigen of unviable cryptococci.

Abstract
The most reliable predictor of treatment efficacy in hepatitis C is HCV viremia decay at week 12 [early virological response (EVR)]. We investigated whether the ability of peripheral blood mononuclear cells (PBMC) to mount an interferon (IFN) response in vitro could be predictive of EVR. Fifteen patients treated with PEG IFNalpha + RBV, with pre-therapy frozen PBMC, were retrospectively selected. After a 3 hr PBMC exposure to IFNalpha in vitro, up-regulation of mRNA for IFN-stimulated genes (ISG) was measured by membrane super-array. ISG mRNA levels in unstimulated PBMC were low, but beta2M and CASP1 were significantly higher in EVR vs non-EVR. ISG mRNA up-regulation by IFN was more pronounced in EVR vs non-EVR. For 7 genes (IP-10, IFIT1, IFIT2, IFIT3, TRAIL, KIAA1628 and OAS2) cut-off levels were established, by ROC analysis, able to correctly classify all EVR and non-EVR. Early virological response to PEG IFNalpha +RBV is correlated with the pre-therapy ability of PBMC to activate an IFN response in vitro. If validated in a wider cohort of patients, the ability of this set of ISG to discriminate between EVR and non-EVR may be useful for pre-therapy evaluation, particularly in patients with unfavourable combinations of conventional response predictors.

Abstract
GB virus C (GBV-C) coinfection has a protective role in Human Immunodeficiency Virus (HIV) infection, and increases the duration of suppression of HIV-1 viremia in patients under Highly Active Anti-Retroviral Therapy (HAART). Since innate antiviral response may be involved in the protection, we analyzed the possible role of GBV-C as activator of innate immunity. To this aim, we measured the extent of activation of the interferon (IFN) system and of circulating Dendritic Cells (DC) in vivo, and the ability of GBV-C to activate these functions in vitro. Activation of IFN system and of circulating DC was compared in GBV-positive and -negative HIV-1 co-infected patients with HAART-driven suppression of HIV-1 viremia. Endogenous levels of IFN-gamma and RNA-dependent protein kinase (PKR) mRNA were significantly higher in peripheral blood mononuclear cells (PBMC) from GBV-C-positive when compared to GBV-C-negative patients. IFN-gamma expression was correlated with all the Interferon response genes (IRGs) and with GBV-C viremia. The frequency of circulating plasmacytoid DC (pDC) expressing the CD80 activation marker was increased in GBV-C-positive patients, and was correlated with GBV-C viral load. In vitro experiments indicated that GBV-C is able to induce IFN-gamma expression in PBMC. In addition, in PBMC cultures GBV-C induced an increase of CD80 expression by pDC, that was reduced by antibody to IFN-gamma. Our data indicate that in HIV-positive patients GBV-C coinfection promotes the activation of IFN-gamma and downstream IRG expression, as well as with the activation/maturation of circulating pDC. GBV-C-driven IFN-gamma activation is, at least in part, responsible for the increased maturation of pDC. This crosstalk may suggest a role for GBV-C coinfection in boosting the innate antiviral response to HIV infection.

Abstract
Background Baseline and follow-up predictors of new AIDS-defining events (ADE) or death among patients who started HAART with CD4+ T-cell counts ≥200 cells/mm3 have rarely been assessed simultaneously. Methods A prospective observational cohort study (1996–2002) is reported. HIV-infected patients initiating HAART with a CD4+ T-cell count ≥200 cells/mm3 were studied. Baseline and time-varying factors were tested for the prediction of new ADE/death using Cox regression models. Results A total of 896 subjects were studied over a median of 5.1 years. The incidence of a new ADE was 1.6 (95% confidence interval 1.3–2.1) per 100 person-years. Among baseline factors, higher CD4+ T-cell counts before HAART were associated with lower risk of ADE/death, but not after adjustment for time-varying factors. On a multivariable analysis including both baseline and time-varying covariates, longer delay from HIV diagnosis to HAART was an independent predictor of ADE/death (per year, hazard ratio [HR] 1.06; P=0.025) and was independent of CD4+ T-cell count before treatment. Longer time spent with HIV RNA <400 copies/ml (per month, HR 0.96; P=0.003) and higher latest CD4+ T-cell count (per log2 cells/mm3, HR 0.65; P<0.001) were found to be protective. Conclusions Patients with higher CD4+ T-cell counts before HAART initiation had a better prognosis. However, except for the delay in starting HAART, viro-immunological evolution outweighed the effect of baseline factors. Moreover, suppressing HIV replication for as long as possible could improve the clinical outcome. Prospective randomized clinical trials to assess the optimal timing of HAART initiation are both feasible and urgently needed.

Abstract
BACKGROUND The epidemiology of acute hepatitis C has changed during the past decade in Western countries. Acute HCV infection has a high rate of chronicity, but it is unclear when patients with acute infection should be treated. METHODS To evaluate current sources of hepatitis C virus (HCV) transmission in Italy and to assess the rate of and factors associated with chronic infection, we enrolled 214 consecutive patients with newly acquired hepatitis C during 1999-2004. The patients were from 12 health care centers throughout the country, and they were followed up for a mean (+/- SD) period of 14+/-15.8 months. Biochemical liver tests were performed, and HCV RNA levels were monitored. RESULTS A total of 146 patients (68%) had symptomatic disease. The most common risk factors for acquiring hepatitis C that were reported were intravenous drug use and medical procedures. The proportion of subjects with spontaneous resolution of infection was 36%. The average timespan from disease onset to HCV RNA clearance was 71 days (range, 27-173 days). In fact, 58 (80%) of 73 patients with self-limiting hepatitis experienced HCV RNA clearance within 3 months of disease onset. Multiple logistic regression analyses showed that none of the variables considered (including asymptomatic disease) were associated with increased risk of developing chronic hepatitis C. CONCLUSIONS These findings underscore the importance of medical procedures as risk factors in the current spread of HCV infection in Italy. Because nearly all patients with acute, self-limiting hepatitis C--both symptomatic and asymptomatic--have spontaneous viral clearance within 3 months of disease onset, it seems reasonable to start treatment after this time period ends to avoid costly and useless treatment.

Abstract
BACKGROUND GB virus C (GBV-C) co-infection is associated with a better prognosis in HIV-infected persons. Since interferon activation can be one of the possible mechanisms involved in GBV-C-driven protection against HIV, we compared the endogenous activation of the interferon system in PBMC from GBV-C-positive and -negative patients infected with HIV-1. METHODS The expression of interferon related genes was analyzed in 20 GBV-C positive and 20 GBV-C-negative HIV-infected patients, comparable in terms of CD4 cell counts and HIV viral loads. The levels of mRNA for interferon-related genes (2-5-OAS, MxA, interferon AR-1 and PKR) in PBMC were measured by real time RT-PCR, using B-actin as internal control. RESULTS The endogenous levels of all the Interferon-related genes in HIV/GBV-C co-infected patients were higher than in HIV mono-infected subjects. The difference was statistically significant for PKR mRNA. Direct positive correlation was found between PKR and all the other interferon-related genes, suggesting a coordinated activation of the interferon system. CONCLUSIONS Enhanced activation of the interferon system occurs in GBV-C-positive, as compared to GBV-C-negative patients harbouring HIV-1. These data may be relevant to understand the GBV-C-driven protection against HIV, suggesting that the endogenous activation of the interferon system can contribute to the control of HIV replication.

Abstract
Hepatitis C virus (HCV) variability is mainly attributed to the ability of the virus to respond to host immune pressure, acting as a driving force for the evolution of quasispecies. This study was aimed at studying the changes in HVR-1 heterogeneity and the evolution of HCV quasispecies in HIV/HCV-coinfected patients according to the pattern of response to highly active antiretroviral therapy (HAART). Sixteen HIV/HCV-coinfected patients harbouring HCV genotype 1 and who had been on HAART for at least 1 year, 8 showing increasing CD4+T-cell counts (immunological responders) and 8 showing a stable or decreasing CD4+ T-cell counts (immunological non-responders), were selected from a prospective cohort study. After 1 year of HAART, 11 patients showed HIV viral load <2.6 log10 cp/ml (virological responders), and 5 showed HIV viral load above this value (virological non-responders). Plasma samples, collected before starting therapy and after 1 year of HAART, underwent clonal sequence analysis for HVR-1 region of HCV. Non-synonymous/synonymous substitutions ratio (Ka/Ks), aminoacidic complexity (normalized Shannon entropy) and diversity (p-distance), were considered as parameters of quasispecies heterogeneity. After 1 year of HAART, heterogeneity of HVR-1 quasispecies significantly decreased in virological non-responders, whereas the heterogeneity tended to increase in virological responders. The differences in the evolution were less stringent, when considering immunological response. On the other hand, profound qualitative modifications of HVR-1 quasispecies were observed only in patients with both immunological and virological HAART response. On the whole, these findings suggest that, in patients undergoing HAART, the extent of HCV variability and the evolution of HVR-1 quasispecies is influenced by the pattern of response to antiretroviral therapy.

Abstract
The prognostic role of GB virus type C (GBV-C) viraemia in HIV-infected subjects treated with highly active antiretroviral therapy (HAART) is still undefined, The aim of this analysis is to assess the relationship between GBV-C infection and response to antiretroviral therapy among HIV-infected subjects initiating HAART when antiretroviral-naive. A prospective, observational study of 400 HIV-infected patients with measurements of GBV-C RNA, hepatitis C virus (HCV) antibodies and HCV RNA determined from plasma stored prior to HAART initiation, Time to virological (achieving HIV RNA ≤500 copies/ml) and immunological success (a CD4+ count increase of ≥200cells/μl), and the time to virological relapse (confirmed HIV RNA >500 copies/ml) were assessed by Kaplan-Meier methods and Cox proportional hazard regression model. Of the subjects, 117 (29.3%) were GBV-C positive and, overall, 351 (87.8%) patients achieved virological success, After controlling for a number of confounders including HCV RNA, GBV-C viraemic patients experienced a significantly lower risk of HIV rebound than those who were GBV-C negative [relative hazard (RH)=0.56, 95% CI: 0.34–0.93, P=0.03], Conversely, the probability of achieving initial virological success or CD4+ count response after HAART did not differ between GBV-C-negative and -positive subjects, These results suggest that GBV-C coinfection may play a role in determining the rate of HIV rebound possibly by competing with HIV replication after HIV load has been successfully suppressed by HAART.

Abstract
BACKGROUND Patients with HIV infection may be a valuable target for assessing the impact of drug-resistant tuberculosis (TB). PATIENTS AND METHODS An observational, prospective study was conducted in 96 infectious disease hospital units in Italy during 1999-2000. A total of 140 HIV-infected patients with diagnosis of TB and with an isolate tested for drug susceptibility entered the analysis. Drug resistance (DR) was defined as resistance to either isoniazid (INH) or rifampin (RIF), while multidrug resistance (MDR) was defined as resistance to INH and RIF. RESULTS A total of 117 (83.6%) episodes of TB were classified as new cases and 23 (16.4%) as previously treated cases. Prevalence of resistance to INH or RIF was 12.8% and 4.3% among new cases, and 17.4% and 26.1% among previously treated cases, respectively. Prevalence rates of DR and MDR were 14.5% and 2.6% among new cases and 30.4% and 12.5% among previously treated cases, respectively. No statistically significant risk factors associated with DR or MDR TB emerged in this analysis. CONCLUSION High prevalence rates of DR and MDR are present among HIV-infected TB patients in Italy, in particular among previously treated cases.

Abstract
High level HIV-1 drug resistance in recently infected treatment-naive individuals correlates with sub-optimal virological responses to highly active antiretroviral therapy (HAART). To determine whether genotypic HIV-1 drug resistance in chronic naive patients, as interpreted by various systems, could predict the virological outcomes of HAART, isolates from patients enrolled in a prospective observational cohort (ICoNA) prior to treatment start were genotyped. Genotypic susceptibility scores (GSS) assigned to the initial HAART regimens using the interpretations of pre-therapy resistance mutations by 13 systems were related to virological outcomes. Of 415 patients, 42 (10%) had at least one major resistance mutation. According to the different interpretations, 1.9–20.5% of patients had some level of resistance to at least one drug in the initial regimen. In multivariable analysis, GSS from two systems significantly predicted the time to virological success: Rega 5.5, for each unit increase in GSS adjusted relative hazard (RH) 1.86 [95% confidence intervals (95% CI): 1.15–3.02] and hivresistanceWeb v3, RH 1.87 (95% CI: 1.00–3.48). With three other systems, GSS showed a trend towards a significant prediction of success: Retrogram 1.6, RH 2.33 (95% CI: 0.98–5.53), Menéndez 2002, RH 2.36 (95% CI: 0.97–5.72) and Stanford hivdb, RH 2.06 (95% CI: 0.94–4.49). Genotypic resistance testing coupled with adequate interpretation in chronic naive patients can usefully identify those at risk of sub-optimal virological response to HAART.

Abstract
Highly active antiretroviral therapy (HAART) greatly reduces the risk of developing tuberculosis for HIV-infected persons. Nonetheless, HIV-associated tuberculosis continues to occur in countries where HAART is widely used. To identify the characteristics of HIV-infected persons who develop tuberculosis in the context of the availability of HAART, the current authors analysed data taken from 271 patients diagnosed, in Italy, during 1999-2000. These patients represent 0.7% of the 40,413 HIV-infected patients cared for in the clinical units participating in this current study. From the data it was observed that 20 patients (7.4%) had a previous episode of tuberculosis whose treatment was not completed. Eighty-one patients (29.9%) were diagnosed with HIV at tuberculosis diagnosis, 108 (39.8%) were aware of their HIV status but were not on antiretroviral treatment and 82 (30.3%) were on antiretroviral treatment. Patients on antiretroviral treatment were significantly less immunosuppressed than patients with HIV diagnosed concurrently with tuberculosis, or other patients not on antiretrovirals (median CD4 lymphocytes count: 220 cells x mm(-3) versus 100 cells x mm(-3), and 109 cells x mm(-3), respectively). No significant differences in clinical presentation of tuberculosis according to antiretroviral therapy status were recorded. Failure of tuberculosis control interventions (e.g. noncompletion of treatment) and of HIV care (delayed diagnosis of HIV infection and suboptimal uptake of therapy) may contribute to continuing occurrence of HIV-associated tuberculosis in a country where highly active antiretroviral therapy is largely available. However, a significant proportion of cases occur in patients who are on antiretroviral treatment.

Abstract
OBJECTIVE The study aimed to characterize neuropsychiatric symptomatology and its evolution in a large group of poststroke patients during their first year. METHOD The Neuropsychiatric Inventory (NPI) was administered to a sample of 124 poststroke patients, divided into three independent groups on the basis of time from stroke (2, 6 and 12 months). The controls were 61 healthy subjects. RESULTS A wide range of neuropsychiatric symptoms was found significant in the poststroke population: mostly depression (61%), irritability (33%), eating disturbances (33%), agitation (28%), apathy (27%) and anxiety (23%). Modifications in terms of greater depression, anxiety, irritability and eating disturbances evolved in the year following stroke. Other symptoms were significantly present depending on time from stroke. Clear relations with other clinical and demographic variables were also found. CONCLUSION Neuropsychiatric symptoms constitute an important part of comorbidity in stroke patients; thus, suitable assessment tools may improve clinical understanding of these patients.

Abstract
We examined the impact of a lamivudine-containing highly active antiretroviral therapy (HAART) regimen on 164 hepatitis B virus/HIV co-infected individuals starting their first HAART. Lamivudine-treated patients (accounting for 73% of the study population) showed a significantly lower level of alanine aminotransferase over follow-up [–81.1 mU/ml mean difference; 95% confidence intervals (95% CI): –30.3; –131.7, P=0.003] and a significantly reduced risk of liver-related morbidity/mortality [Relative hazard (RH)=0.07; 95% CI: 0.01–0.38, P=0.002] than those starting a lamivudine sparing-regimen.

Abstract
It is crucial to ensure an optimal clinical management of HCV infection in HIV-co-infected persons. The reasons for the development of guidelines on HCV-infection treatment in HIV-infected persons arise from the need for a standardised management of HIV/HCV coinfection in our Institute. The aim of these guidelines are: to clarify principles of clinical management of HCV infection in HIV-infected patients to care-providers; to improve the awareness of HIV-infected patients cared for our Institute on current management of HCV infection; to improve the quality of care on this topic. These guidelines, based on Evidence based Medicine principles, have been developed by a panel of experts, who conducted a systematic review of the literature, mainly taking into account current international recommendations. In the present document, the most frequent clinical presentation occurring in the management of HIV/HCV co-infected patients at our Institution are discussed. The adherence to present guidelines and their effectiveness at our Institution, outcome indicators will be evaluated. The present guidelines cannot entirely substitute the judgement of an expert clinician. However, adherence to these guidelines will contribute to the improvement of the standard of care of HIV/HCV-co-infected persons.

Abstract
We studied the predictive value of self-reported adherence and plasma drug concentrations on virological rebound to HAART. Among 238 participants in the AdICoNA study who had viral load ≤500 copies/ml, 42 (17.6%) experienced virological rebound by 96 weeks. Both self-reported non-adherence and sub-optimal concentration were independently associated with a higher risk of virological rebound.

Abstract
ISDR mutation pattern and HVR-1 quasispecies were analyzed in HCV genotype 1b-infected patients treated with either PEG- or STD-IFN plus ribavirin, in order to find virological correlates of therapy outcome. ISDR region analysis, performed at baseline (T0) and at 4 weeks of therapy (T1), indicated that ISDR mutation pattern was not predictive of response to treatment. Moreover, no selection of putative resistant strains in the first month of therapy was observed. Viral load was not correlated with any parameter of HVR-1 heterogeneity. Among the HVR-1 heterogeneity parameters considered, complexity was inversely correlated to viral load decline at T1. In univariate analysis, complexity, proportion of non synonymous substitutions (NS) and NS/S ratio were lower in patients showing virological response at 6 months of treatment. Complexity was the only parameter independently associated with both decline of viral load at T1 and virological response after 6 months, even after adjustment for confounding variables. At the end of treatment or later, these correlations were lost. Evolution pattern of the HVR-1 quasispecies indicated a strong selective pressure in sustained responders, with complete substitution of pre-existing quasispecies, while minor changes occured in non responders. In relapsers both patterns were present at a similar rate. In conclusion, this study shows that HVR-1 heterogeneity may be involved in the early response to combined IFN-RBV therapy. The loss of correlation between viral heterogeneity and therapy outcome at 6 months of therapy, or later, suggests that other factors may play a role in maintaining sustained response to treatment.

Abstract
The genotype of the host plays a crucial role in the pathogenesis of transmissible spongiform encephalopathies (TSEs). In this respect, the most important factor is represented by the gene of the prion protein (PrP). The present work summarizes the currently available knowledge on the genetic basis of TSEs focusing, in particular, on sheep scrapie. Interest in this disease has grown markedly following the discovery of bovine spongiform encephalopathy, both for scientific and health reasons. In Italy, specific research grants from the Ministry of Health and the National Research Council (CNR), together with cooperation between the Istituto Superiore di Sanità and the Istituti Zooprofilattici Sperimentali, have allowed us to study the PrP genotype and to investigate the genetic susceptibility to scrapie in the most important Italian sheep breeds, with special reference to Sarda, Comisana and Massese. The PrP genotype in relation to scrapie susceptibility was also studied in goats of Ionica breed.

Abstract
The aim of this study was to assess the specific influence of poststroke depression (PSD) on both basal functional status and rehabilitation results. We performed a case-control study in 290 stroke inpatients, matched for age (+/-1 year) and onset admission interval (+/-3 days) and divided in two groups according to the presence (PSD+) or absence (PSD-) of PSD. All PSD+ patients were treated with antidepressants (AD), mainly with fluoxetine. PSD+ patients, despite similar severity of stroke, showed greater disability in coping with activities of daily living (ADL) on admission and greater disability both in ADL and mobility at discharge than PSD- patients. Although both groups exhibited similar average functional improvement during rehabilitation, PSD- patients were nearly twice as likely to show excellent recovery both on ADL and mobility as PSD+ patients (OR = 1.95, 95% CI = 1.01-3.75 and OR = 2.23, 95% CI = 1.14-4.35, respectively). All AD drugs improved depressive symptoms. Few relevant side effects were observed: fluoxetine was discontinued in 2 patients because of insomnia and in 2 patients because of nausea; paroxetine was stopped in 1 patient because of nausea and dry mouth. Our results confirm the unfavorable influence of PSD on functional outcome, despite pharmacological treatment.

Abstract
This study describes how hospital-at-home care (HHC) use by persons with acquired immune deficiency syndrome (PWA) has changed since the introduction of combination antiretroviral therapy (ART). For this study, all adult PWA (877) admitted for the first time to the HHC program, established for PWAs in the metropolitan area of Rome, between January 1994 and December 1998, were enrolled. Temporal changes in sociodemographic and clinical characteristics were evaluated. For subjects who concluded their first HHC cycle (851/877), the reasons for ending the service were assessed over time. From 1994 to 1998, the proportion of patients admitted to HHC of those living with AIDS in the Rome area decreased significantly (from 15.1% to 7.5%), while the median CD4+ cell count at HHC entry increased significantly. The proportion of patients referred to outpatient services at the end of their cycle of HHC increased sevenfold from 1994 to 1998, with a steep increase between 1996 and 1997. In multivariate analysis, only the use of triple-combination ART was significantly associated with referral to outpatient care (odds ratio [OR] = 4.26; 95%, confidence interval [CI] = 1.94-9.34). The results suggest that HHC use by PWAs in the ART era has diminished, while the HHC use pattern has also changed: there is a growing tendency to provide care to patients with less advanced human immunodeficiency virus (HIV) disease, prior to the beneficial effects of drugs, and the consequent referral to outpatient care.

Abstract
The aim was to evaluate the effects of poststroke depression and antidepressant therapy on the improvement of motor scores and disability, to verify if the negative effects of poststroke depression on functional recovery could be counterbalanced by taking antidepressant drugs. RESULTS OBTAINED BEFORE, DURING, AND AFTER REHABILITATION: On the Barthel index, Canadian neurological scale, and Rivermead mobility index-by 49 depressed patients with stroke, who had been treated (n=25) or not treated (n=24) according to the different therapeutic approaches of their physicians, were compared with results similarly obtained by 15 non-depressed patients with stroke. Analysis was by multivariate analysis of variance for repeated measures There was a non-significant difference between the groups in their motor and functional scores, and a significant improvement on time. A significant interaction between group and time was seen. This interaction was particularly significant on the Rivermead mobility index, and was due to the fact that the recovery of non-treated depressed patients with stroke was less than the non-depressed and the depressed but treated patients with stroke. Furthermore, recovery from depression was significantly greater in treated than in non-treated depressed patients with stroke. In conclusion, poststroke depression has negative effects on functional recovery, and a pharmacological treatment of depression can counterbalance this effect.

Abstract
The aim of this study was to assess the degree of implementation of national guidelines for isoniazid preventive therapy (IPT) among human immunodeficiency virus (HIV)-infected individuals and factors affecting the impact of the programme. Twenty-eight infectious disease hospital units in Italy participated in this observational, multicentre, prospective cohort study. A number of HIV-infected subjects, (n=1,705) seen for the first time as outpatients, were included in this analysis. Of the subjects considered, 1,215 out of the 1,705 completed purified protein derivative (PPD) screening. Variables independently associated with offering and completion of PPD screening included having acquired immune deficiency syndrome (AIDS), higher educational levels and currently receiving therapy. Overall, 103 subjects were identified as candidates for IPT. Of these subjects, five had tuberculosis and 15 had contraindications to IPT. Forty subjects agreed to start IPT, and 29 completed a full-course regimen. The incidence of tuberculosis among IPT candidates who either did not begin or discontinued IPT was 6.1 per 100 person-yrs, while no cases of tuberculosis were observed in subjects completing IPT. Several factors may limit the implementation of an isoniazid preventive therapy programme for human immunodeficiency virus-infected persons. Physicians fail to offer purified protein derivative screening to patients with high degrees of immunodeficiency, and those with a more intense workload seem to pay less attention to this test. The high number of contraindications among patients and their low level of acceptance further affects the impact of isoniazid preventive therapy.

Abstract
We conducted a multicenter, hospital-based case-control study to identify specific characteristics of AIDS patients which determine referral to hospital care at home. The cases were patients referred to a hospital-based home care scheme, in the metropolitan area of Rome, during 1997. Each case was matched with two controls. Social, demographic and clinical characteristics were collected at referral. Univariate and multivariate analysis were performed. In the study period, 119 cases and 238 controls were recruited. In logistic regression analysis, social characteristics were not found to affect referral to the hospital-at-home scheme. A severely impaired functional status--assessed by the Functional Independent Measure--identified by a score below 100 (Odds Ratio [OR]=15.2, 95% confidence interval [CI] 2.8-82.7), and the need for prolonged intravenous therapy (OR=12.4, 95% CI=3.3-46.3) were the only two independent predictors of home-care referral. We conclude that home care, even in a period when new potent combination antiretroviral therapies are widely available, is an important integrated service component for persons with AIDS with severe functional impairment or requiring intravenous therapy.

Abstract
The spread of the HIV epidemic has been one of the major factors contributing to the worldwide resurgence of the tuberculosis epidemic. It was estimated that in 1997 8% of global tuberculosis cases may be attributed to HIV infection. The highest burden of HIV-associated tuberculosis is concentrated in resource-poor countries. HIV infection increases the individual's susceptibility to tuberculosis by impairing immune response to mycobacterial infection. In addition, HIV-associated tuberculosis is more difficult both to diagnose and to treat. A strong international commitment to the development of innovative strategies of diagnosis, treatment, and the prevention and integration between tuberculosis and HIV prevention programs are urgently needed to face the threat of HIV-associated tuberculosis.
