    Background: Advanced Hepatocarcinoma (HCC) is an important health problem worldwide. Recently, the REFLECT trial demonstrated the non-inferiority of Lenvatinib compared to Sorafenib in I line setting, thus leading to the approval of new first-line standard of care, along with Sorafenib. Aims and methods: With aim to evaluate the optimal choice between Sorafenib and Lenvatinib as primary treatment in clinical practice, we performed a multicentric analysis with the propensity score matching on 184 HCC patients. Results: The median overall survival (OS) were 15.2 and 10.5 months for Lenvatinib and Sorafenib arm, respectively. The median progression-free survival (PFS) was 7.0 and 4.5 months for Lenvatinib and Sorafenib arm, respectively. Patients treated with Lenvatinib showed a 36% reduction of death risk (p = 0.0156), a 29% reduction of progression risk (p = 0.0446), a higher response rate (p < 0.00001) and a higher disease control rate (p = 0.002). Sorafenib showed to be correlated with more hand-foot skin reaction and Lenvatinib with more hypertension and fatigue. We highlighted the prognostic role of Barcelona Clinic Liver Cancer (BCLC) stage, Eastern Cooperative Oncology Group Performance Status (ECOG-PS), bilirubin, alkaline phosphatase and eosinophils for Sorafenib. Conversely, albumin, aspartate aminotransferase (AST), alkaline phosphatase and Neutrophil-Lymphocyte Ratio (NLR) resulted prognostic in Lenvatinib arm. Finally, we highlighted the positive predictive role of albumin > Normal Value (NV), ECOG > 0, NLR < 3, absence of Hepatitis C Virus positivity, and presence of portal vein thrombosis in favor of Lenvatinib arm. Eosinophil < 50 and ECOG > 0 negatively predicted the response to Sorafenib. Conclusion: SLenvatinib showed to better perform in a real-word setting compared to Sorafenib. More researches are needed to validate the predictor factors of response to Lenvatinib rather than Sorafenib

    <p>Abstract</p> <p>Background</p> <p>The function of promyelocytic leukemia (PML) bodies is not well known but plays an important role in controlling cell proliferation, apoptosis and senescence. This study was undertaken to analyze the clinical significance of PML body expression in primary tumor samples from malignant fibrous histiocytoma (MFH) and liposarcoma patients.</p> <p>Methods</p> <p>We studied MFH and liposarcoma samples from 55 patients for PML bodies. Fluorescent immunostaining of PML bodies was performed in the paraffin-embedded tumor sections.</p> <p>Results</p> <p>PML body immunostaining was identified in 63.9% of MFH and 63.2% of liposarcoma samples. PML body expression rates of all sarcoma cells were 1.5 ± 1.8% (range: 0–7.0) in MFH and 1.3 ± 1.4% (0–5.2) in liposarcoma samples. PML body expression (p = 0.0053) and a high rate of PML body expression (p = 0.0012) were significantly greater prognostic risk factors for death than the other clinical factors in MFH patients. All liposarcoma patients without expression of PML were disease free at the end of the study.</p> <p>Conclusion</p> <p>Our study suggests that the presence of PML bodies may indicate a poor prognosis for MFH and liposarcoma patients.</p

    Correlation between p38 mitogen-activated protein kinase and human telomerase reverse transcriptase in sarcomas

    <p>Abstract</p> <p>Background</p> <p>One of the major components of telomerase is the human telomerase reverse transcriptase (hTERT) as the catalytic protein. hTERT mRNA expression are reported to be associated with prognosis and tumor progression in several sarcomas. However, there is no clear understanding of the mechanisms of hTERT in human sarcomas. Recent studies have suggested that signals transmitted through p38 mitogen-activated protein kinase (MAPK) can increase or decrease hTERT transcription in human cells. The purpose of this study was to analyse the correlation between p38 MAPK and hTERT in sarcoma samples.</p> <p>Methods</p> <p>We investigated 36 soft tissue malignant fibrous histiocytomas (MFH), 24 liposarcomas (LS) and 9 bone MFH samples for hTERT and p38 MAPK expression. Quantitative detection of hTERT and p38 MAPK was performed by RT-PCR.</p> <p>Results</p> <p>There was a significant positive correlation between the values of hTERT and p38 MAPK in all samples (r = 0.445, p = 0.0001), soft tissue MFH (r = 0.352, p = 0.0352), LS (r = 0.704, p = 0.0001) and bone MFH samples (r = 0.802, p = 0.0093). Patients who had a higher than average expression of p38 MAPK had a significantly worse prognosis than other patients (p = 0.0036).</p> <p>Conclusions</p> <p>p38 MAPK may play a role in up-regulation of hTERT, and therefore, p38 MAPK may be a useful marker in the assessment of hTERT and patients' prognosis in sarcomas.</p

    Outbreak of Klebsiella pneumoniae Carbapenemase-Producing Citrobacter freundii at a Tertiary Acute Care Facility in Miami, Florida

    OBJECTIVE To describe the investigation and control of a rare cluster of Klebsiella pneumoniae carbapenemase-producing Citrobacter freundii in a hospital in southern Florida. METHODS An epidemiologic investigation, review of infection prevention procedures, and molecular studies including whole genome sequencing were conducted. RESULTS An outbreak of K. pneumoniae carbapenemase-3-producing C. freundii was identified at a tertiary hospital in Florida in 2014. Of the 6 cases identified, 3 occurred in the same intensive care unit and were caused by the same clone. For 2 of the 3 remaining cases, the isolates had low carbapenem minimum inhibitory concentrations and were unrelated by whole genome sequencing. As a response to the outbreak, supplementary environmental cleaning was implemented, including closure and terminal cleaning of the unit where the 3 cases clustered, in addition to the infection control bundle already in place at the time. No further cases were identified after these additional interventions. CONCLUSIONS Although C. freundii is not a species that commonly demonstrates carbapenem resistance, our findings suggest that carbapenemase-producing C. freundii may be underdetected even when active surveillance is in place and has a potential to cause hospital outbreak.

    OBJECTIVETo concomitantly determine the differential degrees of air and environmental contamination by Acinetobacter baumannii based on anatomic source of colonization and type of ICU layout (single-occupancy vs open layout).DESIGNLongitudinal prospective surveillance study of air and environmental surfaces in patient rooms.SETTINGA 1,500-bed public teaching hospital in Miami, Florida.PATIENTSConsecutive A. baumannii–colonized patients admitted to our ICUs between October 2013 and February 2014.METHODSAir and environmental surfaces of the rooms of A. baumannii–colonized patients were sampled daily for up to 10 days. Pulsed-field gel electrophoresis (PFGE) was used to type and match the matching air, environmental, and clinical A. baumannii isolates.RESULTSA total of 25 A. baumannii–colonized patients were identified during the study period; 17 were colonized in the respiratory tract and 8 were colonized in the rectum. In rooms with rectally colonized patients, 38.3% of air samples were positive for A. baumannii; in rooms of patients with respiratory colonization, 13.1% of air samples were positive (P=.0001). In rooms with rectally colonized patients, 15.5% of environmental samples were positive for A. baumannii; in rooms of patients with respiratory colonization, 9.5% of environmental samples were positive (P=.02). The rates of air contamination in the open-layout and single-occupancy ICUs were 17.9% and 21.8%, respectively (P=.5). Environmental surfaces were positive in 9.5% of instances in open-layout ICUs versus 13.4% in single-occupancy ICUs (P=.09).CONCLUSIONSAir and environmental surface contaminations were significantly greater among rectally colonized patients; however, ICU layout did not influence the rate of contamination.Infect Control Hosp Epidemiol 2016;37:777–78
