Literacy, Place, and Migration in Philadelphia among Ethnic Chinese

We introduce the need for scholars interested in literacy, geography, and cultural studies to examine the role of English language literacy in shaping assimilation experiences of recent immigrant groups. We consider a case study of English language self-efficacy among ethnic Chinese immigrants in the Philadelphia metropolitan area to suggest how language, place, and economic participation are mutually constructed. We conducted interviews with 21 individuals to gain insights about how they perceived this relationship. We also considered the effects of English language self-efficacy on the geographic extent of their daily activities. Perhaps it is not surprising that those who reported stronger English language skills had larger activity spheres in the metropolitan region. Among those who did not note strong language skills, Philadelphia’s historic Chinatown remained prominent as a place of economic participation and center for daily activities and cultural cohesion. We suggest that more attention to the role of literacy and language self-efficacy is warranted among geographers interested in migration studies, assimilation experiences, and workforce participation issues related to immigrant groups

Phytosociology and taxonomic notes on some endemic-rich associations of the Naples Gulf

The Gulf of Naples is an important centre of endemism, well known from the floristic point of view, but much less from the phytosociological one. In this paper we investigated the non-forest vegetation focusing on communities rich in endemics. We described two communities as new: Eryngio amethystini-Santolinetum neapolitanae for the garrigues on limestone, Globulario neapolitanae-Loniceretum stabianae for the vegetation on dolomitic rocks, both from the Lattari mountains, and we extend the area of Crithmo maritimi-Limonietum cumani for the vegetation on volcanic rocks and rarely on limestones along the coast, which was known for a few localities. The syntaxonomical position and the phytogeographical context of these communities are discussed. A few taxonomic notes are added on rare or interesting species retrieved in the course of the enquiry

Biohazard in air-conditioning systems installed in health facilities

The project "Biological hazard related to the operation of air-conditioning systems in sanitary environments in the province of Avellino" has had, as its main objective, the microbiological monitoring of the environments hospitals in order to evaluate the microbiological quality of the air, through procedures and criteria for sampling the environmental microbial flora. This procedure aims to assess and manage risks related to the hygiene of air treatment plants (UTA), which must be periodically subjected to checks, maintenance, cleaning and sanitisation in order to protect the health of Workers according to technical standards and national guidelines. Most important was the characterisation at the level of species and gender of the main microbiological contaminants present within the samples investigated. The entire trial was carried out on a temporal scale taking into account the frequency of the UTA maintenance activities and thus establishing the monitoring plan. In order to assess the effectiveness of the maintenance plan and the efficiency of the actions of sanitizations, withdrawals should be made at three different times or immediately after ordinary maintenance, halfway between the first and second Maintenance and immediately before the second maintenance. This way you can monitor the presence of different bacterial contaminants in time. The quantitative and qualitative analysis of bacteria, pathogens and not, in hospital environments aims to prevent the onset and spread of pathologies. In particular, the monitoring of air handling units is of fundamental importance since such plants can cause the diffusion of many pollutants, coming from outside or inside, resulting from residues of materials from Construction, from remnants of plant and animal origin (pigeons, mice, insects) or moulds and bacteria that can contaminate the water and the surfaces inside the aeraulic plants. The molecular-based taxonomic characterization of the most representative species in the test specimens has as its main purpose the identification of any "sentinel" markers as well as indicators of biohazard

Involvement of the Soluble Urokinase Receptor in Chondrosarcoma Cell Mobilization

High levels of urokinase receptor (uPAR) in tissue and serum of patients with chondrosarcoma correlate with poor prognosis. First, we analyzed the uPAR levels in tissues and plasma of five patients affected by chondrosarcoma. Interestingly, very high levels of uPAR and its soluble forms (SuPAR) were found on tumor cell surfaces and plasma, respectively, of two patients with lung metastases. Therefore, to investigate the role of SuPAR in chondrosaromas, we generated a primary cell culture from a chondrosarcoma tissue overexpressing uPAR on cell surfaces. We found that chondrosarcoma-like primary culture cells release a large amount of SuPAR in the medium. In vitro, SuPAR elicits chondrosarcoma cell migration likely through its uPAR88-92 sequence, since the DII88-183 or DIIDIIR88-284 uPAR domains retain motogen effect whereas DI1-87 or DIII184-284 domains, both lacking the uPAR88-92 sequence, are ineffective. Chondrosarcoma cells cross matrigel in response to SuPAR, and their invasion capability is abrogated by RERF peptide which inhibits uPAR88-92 signalling. These findings assign a role to uPAR in mobilizing chondrosarcoma cells and suggest that RERF peptide may be regarded as a prototype to generate new therapeutics for the chondrosarcoma treatment

Incidence of bloodstream infections, length of hospital stay and survival in patients with recurrent Clostridioides difficile infection treated with fecal microbiota transplantation or antibiotics: a prospective cohort study

Background: Clostridioides difficile infection (CDI) is a risk factor for bloodstream infections (BSI). Fecal microbiota transplantation (FMT) is more effective than antibiotics in treating recurrent CDI, but its efficacy in preventing CDI-related BSI is uncertain. Objective: To assess incidence of primary BSI in patients with recurrent CDI treated with FMT compared with patients treated with antibiotics. Design: Prospective cohort study. FMT and antibiotic treated patients were matched using propensity score. Setting: Single academic medical center. Patients: 290 inpatients with recurrent CDI; 57 patients per treatment in matched cohort. Interventions: FMT or antibiotics. Measurements: Our primary outcome was the development of primary BSI within a 90-day follow-up. Secondary outcomes were length of hospitalization, and overall survival (OS) at 90 days. Results: 109 patients were treated with FMT, and 181 received antibiotics. Five patients in the FMT group and 40 in the antibiotic group developed BSI. Due to differences in the patients treated with FMT and antibiotics in a number of baseline characteristics including the number of recurrences and CDI severity, comparative analyses were limited to the matched cohort. Subjects in the FMT group experienced a 23% lower risk of developing BSI (95% confidence interval 10-35%), 14 fewer days of hospitalization (95% confidence interval 9-20 days), and a 32% increase in OS (95% confidence interval 16-47%) compared with the antibiotic group. Limitations: Non-randomized study with potential for unmeasured/residual confounding. Limited generalizability of the propensity score-matched cohort. Conclusion: In a propensity score-matched cohort, patients with recurrent CDI treated with FMT were less likely to develop primary BSI

Support systems to guide clinical decision-making in precision oncology: The Cancer Core Europe Molecular Tumor Board Portal.

To the editor: the optimal management of cancer patients is increasingly dependent on individualized treatments guided by tumor sequencing data. As comprehensive genomic tests become routine in many disease settings and academic centers promote omics-guided clinical trial recruitment, accurate and scalable data interpretation represents a major challenge. The meticulous task of matching tumor alterations with approved or experimental therapies relies heavily on the expertise of each center

Future perspectives in melanoma research: meeting report from the “Melanoma Bridge”, Napoli, December 5th-8th 2013

The fourth “Melanoma Bridge Meeting” took place in Naples, December 5 to 8th, 2013. The four topics discussed at this meeting were: Diagnosis and New Procedures, Molecular Advances and Combination Therapies, News in Immunotherapy, and Tumor Microenvironment and Biomarkers. Until recently systemic therapy for metastatic melanoma patients was ineffective, but recent research in tumor biology and immunology has led to the development of new targeted and immunotherapeutic agents that prolong progression-free survival (PFS) and overall survival (OS). New therapies, such as mitogen-activated protein kinase (MAPK) pathway inhibitors, like BRAF and MEK inhibitors, as well as other signaling pathways inhibitors, are being tested in metastatic melanoma either as monotherapy or in combination, and have yielded promising results. Improved survival rates have also been observed with immune therapy for patients with metastatic melanoma. Immune-modulating antibodies came to the forefront with anti-CTLA-4, programmed cell death-1 (PD-1) and PD-1 ligand 1 (PD-L1) pathway blocking antibodies that result in durable responses in a subset of melanoma patients. Agents targeting other immune inhibitory (e.g., Tim-3) or immune stimulating (e.g., CD137) receptors and other approaches such as adoptive cell transfer demonstrate clinical benefit in melanoma as well. This meeting’s specific focus was on advances in targeted therapy and immunotherapy. Both combination targeted therapy approaches and different immunotherapies were discussed. Similarly to the previous meetings, the importance of biomarkers for clinical application as markers for diagnosis, prognosis and prediction of treatment response was an integral part of the meeting. Significant consideration was given to issues surrounding the development of novel therapeutic targets as further study of patterns of resistance to both immunologic and targeted drugs are paramount to future drug development to guide existing and future therapies. The overall emphasis on biomarkers supports novel concepts toward integrating biomarkers into contemporary clinical management of patients with melanoma across the entire spectrum of disease stage. Translation of the knowledge gained from the biology of tumor microenvironment across different tumors represents a bridge to impact on prognosis and response to therapy in melanoma

Towards the introduction of the ‘Immunoscore’ in the classification of malignant tumours

The American Joint Committee on Cancer/Union Internationale Contre le Cancer (AJCC/UICC) TNM staging system provides the most reliable guidelines for the routine prognostication and treatment of colorectal carcinoma. This traditional tumour staging summarizes data on tumour burden (T), the presence of cancer cells in draining and regional lymph nodes (N) and evidence for distant metastases (M). However, it is now recognized that the clinical outcome can vary significantly among patients within the same stage. The current classification provides limited prognostic information and does not predict response to therapy. Multiple ways to classify cancer and to distinguish different subtypes of colorectal cancer have been proposed, including morphology, cell origin, molecular pathways, mutation status and gene expression-based stratification. These parameters rely on tumour-cell characteristics. Extensive literature has investigated the host immune response against cancer and demonstrated the prognostic impact of the in situ immune cell infiltrate in tumours. A methodology named ‘Immunoscore’ has been defined to quantify the in situ immune infiltrate. In colorectal cancer, the Immunoscore may add to the significance of the current AJCC/UICC TNM classification, since it has been demonstrated to be a prognostic factor superior to the AJCC/UICC TNM classification. An international consortium has been initiated to validate and promote the Immunoscore in routine clinical settings. The results of this international consortium may result in the implementation of the Immunoscore as a new component for the classification of cancer, designated TNM-I (TNM-Immune). © 2013 The Authors.

A systematic approach to biomarker discovery; Preamble to "the iSBTc-FDA taskforce on immunotherapy biomarkers"

The International Society for the Biological Therapy of Cancer (iSBTc) has initiated in collaboration with the United States Food and Drug Administration (FDA) a programmatic look at innovative avenues for the identification of relevant parameters to assist clinical and basic scientists who study the natural course of host/tumor interactions or their response to immune manipulation. The task force has two primary goals: 1) identify best practices of standardized and validated immune monitoring procedures and assays to promote inter-trial comparisons and 2) develop strategies for the identification of novel biomarkers that may enhance our understating of principles governing human cancer immune biology and, consequently, implement their clinical application. Two working groups were created that will report the developed best practices at an NCI/FDA/iSBTc sponsored workshop tied to the annual meeting of the iSBTc to be held in Washington DC in the Fall of 2009. This foreword provides an overview of the task force and invites feedback from readers that might be incorporated in the discussions and in the final document
