Post-hospital care pathway for individuals with hip fracture: what is the optimal setting and rehabilitation intensity? An observational study

PURPOSE: Health systems are using ever-increasing resources on treating hip fractures. Optimal post-hospital care needs to be defined to design an effective care pathway. The aim of the present study was to describe the post-hospital care pathway of individuals with hip fracture and to assess its association with the degree of recovery of independence achieved four months after surgery.MATERIALS AND METHODS: A prognostic multicentric cohort study was conducted. All patients aged 65years and over who were admitted with a diagnosis of fragility hip fracture were enrolled. After the hospital discharge, the patients were followed either at an inpatient rehabilitation facility with an intensive or extensive regimen, a nursing home, a long-term care facility or at home. Among the various care pathways, the intensity of rehabilitation differed according to its duration, frequency of sessions, and activities proposed. Primary outcome was the patient's degree of independence achieved four months after surgery, as measured with Activities of Daily Living scale. Several covariates were collected to test the correlation between the different post-hospital care pathways and the recovery of independence.RESULTS: A total of 923 patients completed the follow-up. A post- hospital rehabilitation pathway was indicated for 88.2% of the patients. The extensive rehabilitation pathway, indicated for 36.7% of the patients, was the most common. The intensive rehabilitation pathway gave better results in terms of independence at four-month follow up, leading to a median ADL score of 1.4 (95% CI 1.0-2.0). The other care pathways did not show significant difference between each other.CONCLUSIONS: High-intensity rehabilitation was associated to better results in terms of recovering of Activities of Daily Living.IMPLICATIONS FOR REHABILITATIONPost-hospital care pathways that include an intensive rehabilitation treatment should be improved/supported to make them available to a larger number of hip fracture patients.Patient selection criteria for post-hospital rehabilitation pathways should be standardized to optimize available healthcare resources.A cost-effectiveness analysis should be performed to analyze the economic sustainability of each post-hospital care pathway

Mycobacterium bovis BCG: the importance of an accurate identification in the diagnostic routine

M. bovis BCG is used clinically in the immunotherapy treatment of superficial bladder cancer to prevent progression to invasive disease, leading in some cases to a severe localized inflammation or disseminated infections. For this reason, an accurate and early identification of this particular microorganism is clinically relevant.We describe a case-report of bladder cancer with a urine culture-positive for mycobacteria initially diagnosed as MTB complex infection and later identified as BCG disease by molecular methods

Pretreatment HIV drug resistance and treatment failure in non-Italian HIV-1-infected patients enrolled in ARCA

Abstract BACKGROUND: An increase in pretreatment drug resistance (PDR) to first-line antiretroviral therapy (ART) in low-income countries has been recently described. Herein we analyze the prevalence of PDR and risk of virologic failure (VF) over time among migrants to Italy enrolled in ARCA. METHODS: HIV-1 sequences from ART-na\uefve patients of non-Italian-nationality were retrieved from ARCA database from 1998 to 2017. PDR was defined by at least one mutation from the reference 2009-WHO-surveillance-list. RESULTS: Protease/reverse-transcriptase sequences from 1,155 patients, mainly migrants from Sub-Saharan Africa (SSA) (42%), followed by Latin America (LA) (25%) and Western Countries (WE) (21%), were included. PDR was detected in 8.6% of sequences (13.1% vs 5.8% for B and non-B strains, respectively, p<0.001). 2.1% of patients carried a PDR for protease inhibitors (PIs) (2.1% vs 2.3%, p=0.893), 3.9% for nucleos(t)ide-reverse-transcriptase inhibitors (NRTI) (6.8% vs 2.1%, p<0.001) and 4.3% for non-nucleos(t)ide-reverse-transcriptase inhibitors (NNRTI) (6.3% vs 3.1%, p=0.013). Overall, prevalence of PDR over the years remained stable, while it decreased for PIs in LA (p=0.021), and for NRTI (p=0.020) among migrants from WE. Having more than 1 class of PDR (p=0.015 vs. absence of PDR), higher viral load at diagnosis (p=0.008) and being migrants from SSA (p=0.001 vs. WE) were predictive of VF, while a recent calendar year of diagnosis (p<0.001) was protective for VF. CONCLUSIONS: PDR appeared to be stable over the years in migrants to Italy enrolled in ARCA; however, it still remains an important cause of VF together with VL at diagnosis

Impact of the M184V resistance mutation on virological efficacy and durability of lamivudine-based dual antiretroviral regimens as maintenance therapy in individuals with suppressed HIV-1 RNA: A cohort study

Background. Dual therapy (DT) with boosted protease inhibitors (bPIs) plus lamivudine has been shown to be superior to bPI monotherapy in virologically suppressed patients despite previous selection of the lamivudine resistance M184V mutation. We compared the virological efficacy of lamivudine-based DT in patients with and without a history of M184V detection. Methods. We retrospectively analyzed patients with HIV-RNA ≤50 copies/mL switching to DT with at least 1 previous resistance genotype in the ARCA database. Time to virological failure (VF; HIV-RNA ≥200 copies/mL or 2 consecutive HIV-RNA >50 copies/mL) and to treatment discontinuation (TD) was analyzed by survival analysis. Results. Four hundred thirty-six patients switching to lamivudine plus bPIs (70%) or integrase inhibitors (30%) were included. Patients with M184V (n = 87) were older, had lower nadir CD4+ cell count, longer duration of antiretroviral therapy and of virologic suppression, and higher rate of hepatitis C virus infection compared with patients without M184V. The 3-year probability of remaining free from VF was 91.9% (95% confidence interval [CI], 86.6-97.2) without M184V and 87.8% (95% CI, 78.4-97.2) with M184V (P = .323). The time to TD did not differ between groups. Multivariate analysis adjusting for baseline variables differing between groups also did not detect M184V as being associated with VF or TD; however, the 3-year probability of remaining free of viral blips (isolated HIV-RNA 51-199 copies/mL) was 79.8% (95% CI, 67.8%-91.8%) with M184V vs 90.1% (95% CI, 84.0%-96.2%) without M184V (P = .016). Conclusions. Previous selection of M184V did not increase the risk of VF or TD with lamivudine-based DT but was associated with a higher probability of viral blips

Evolution of transmitted HIV-1 drug resistance and viral subtypes circulation in Italy from 2006 to 2016

Objectives: The aim was to evaluate the evolution of transmitted HIV-1 drug resistance (TDR) prevalence in antiretroviral therapy (ART)-na\uefve patients from 2006 to 2016. Methods: HIV-1 sequences were retrieved from the Antiviral Response Cohort Analysis (ARCA) database and TDR was defined as detection of at least one mutation from the World Health Organization (WHO) surveillance list. Results: We included protease/reverse transcriptase sequences from 3573 patients; 455 had also integrase sequences. Overall, 68.1% of the patients were Italian, the median CD4 count was 348 cells/\u3bcL [interquartile range (IQR) 169\u2013521 cells/\u3bcL], and the median viral load was 4.7 log10 HIV-1 RNA copies/mL (IQR 4.1\u20135.3 log10 copies/mL). TDR was detected in 10.3% of patients: 6% carried mutations to nucleos(t)ide reverse transcriptase inhibitors (NRTIs), 4.4% to nonnucleos(t)ide reverse transcriptase inhibitors (NNRTIs), 2.3% to protease inhibitors (PIs), 0.2% to integrase strand transfer inhibitors (INSTIs) and 2.1% to at least two drug classes. TDR declined from 14.5% in 2006 to 7.3% in 2016 (P = 0.003): TDR to NRTIs from 9.9 to 2.9% (P = 0.003) and TDR to NNRTIs from 5.1 to 3.7% (P = 0.028); PI TDR remained stable. The proportion carrying subtype B virus declined from 76.5 to 50% (P < 0.001). The prevalence of TDR was higher in subtype B vs. non-B (12.6 vs. 4.9%, respectively; P < 0.001) and declined significantly in subtype B (from 17.1 to 8.8%; P = 0.04) but not in non-B subtypes (from 6.1 to 5.8%; P = 0.44). Adjusting for country of origin, predictors of TDR were subtype B [adjusted odds ratio (AOR) for subtype B vs. non-B 2.91; 95% confidence interval (CI) 1.93\u20134.39; P < 0.001], lower viral load (per log10 higher: AOR 0.86; 95% CI 0.75\u20130.99; P = 0.03), site in northern Italy (AOR for southern Italy/island vs. northern Italy, 0.61; 95% CI 0.40\u20130.91; P = 0.01), and earlier calendar year (per 1 year more recent: AOR 0.95; 95% CI 0.91\u20130.99; P = 0.02). Conclusions: The prevalence of HIV-1 TDR has declined during the last 10 years in Italy

The role of baseline HIV-1 RNA, drug resistance, and regimen type as determinants of response to first-line antiretroviral therapy

The factors influencing virological response to first-line combined antiretroviral therapy (cART) in an Italian cohort of HIV-1-infected patients were examined. Eligible patients were those enrolled in a national prospective observational cohort (Antiretroviral Resistance Cohort Analysis), starting first-line cART between 2001 and 2011 and who had at least one follow-up of HIV-1 RNA. The primary endpoint was virological success, defined as the first viral load 100,000 copies/ml, virologic success was only associated with the use of integrase inhibitors in the first cART regimen. Independent predictors of immunological success were baseline CD4+ cell count and wGSS <3. High baseline HIV-1 RNA, predicted activity of the first-line regimen based on genotypic resistance testing, gender, and use of new agents were found to predict time to achieve virological success. The type of initial nucleoside analog backbone was not found to predict virological response

Detection of drug resistance mutations at low plasma HIV-1 RNA load in a European multicentre cohort study

Guidelines indicate a plasma HIV-1 RNA load of 500-1000 copies/mL as the minimal threshold for antiretroviral drug resistance testing. Resistance testing at lower viral load levels may be useful to guide timely treatment switches, although data on the clinical utility of this remain limited. We report here the influence of viral load levels on the probability of detecting drug resistance mutations (DRMs) and other mutations by routine genotypic testing in a large multicentre European cohort, with a focus on tests performed at a viral load <1000 copies/mL
