Analysing occupational safety culture through mass media monitoring

In the last years, a group of researchers within the National Institute for Insurance against Accidents at Work (INAIL) has launched a pilot project about mass media monitoring in order to find out how the press deal with the culture of safety and health at work. To monitor mass media, the Institute has created a relational database of news concerning occupational injuries and diseases, that was filled with information obtained from the newspaper articles about work-related accidents and incidents, including the text itself of the articles. In keeping with that, the ultimate objective is to identify the major lines for awareness-raising actions on safety and health at work. In a first phase of this project, 1,858 news articles regarding 580 different accidents were collected; for each injury, not only the news texts but also several variables were identified. Our hypothesis is that, for different kind of accidents, a different language is used by journalists to narrate the events. To verify it, a text clustering procedure is implemented on the articles, together with a Lexical Correspondence Analysis; our purpose is to find language distinctions connected to groups of similar injuries. The identification of various ways in reporting the events, in fact, could provide new elements to describe safety knowledge, also establishing collaborations with journalists in order to enhance the communication and raise people attention toward workers' safety

Analgesic effectiveness and tolerability of oral oxycodone/naloxone and pregabalin in patients with lung cancer and neuropathic pain. An observational analysis

INTRODUCTION: Cancer-related pain has a severe negative impact on quality of life. Combination analgesic therapy with oxycodone and pregabalin is effective for treating neuropathic cancer pain. We investigated the efficacy and tolerability of a dose-escalation combination therapy with prolonged-release oxycodone/naloxone (OXN-PR) and pregabalin in patients with non-small-cell lung cancer and severe neuropathic pain. METHODS: This was a 4-week, open-label, observational study. Patients were treated with OXN-PR and pregabalin. Average pain intensity ([API] measured on a 0-10 numerical rating scale) and neuropathic pain (Douleur Neuropathique 4) were assessed at study entry and at follow-up visits. The primary endpoint was response to treatment, defined as a reduction of API at T28 ≥30% from baseline. Secondary endpoints included other efficacy measures, as well as patient satisfaction and quality of life (Brief Pain Inventory Short Form), Hospital Anxiety and Depression Scale, and Symptom Distress Scale; bowel function was also assessed. RESULTS: A total of 56 patients were enrolled. API at baseline was 8.0±0.9, and decreased after 4 weeks by 48% (4.2±1.9; P<0.0001 vs baseline); 46 (82.1%) patients responded to treatment. Significant improvements were also reported in number/severity of breakthrough cancer pain episodes (P=0.001), Brief Pain Inventory Short Form (P=0.0002), Symptom Distress Scale (P<0.0001), Hospital Anxiety and Depression Scale depression (P=0.0006) and anxiety (P<0.0001) subscales, and bowel function (P=0.0003). At study end, 37 (66.0%) patients were satisfied/very satisfied with the new analgesic treatment. Combination therapy had a good safety profile. CONCLUSION: OXN-PR and pregabalin were safe and highly effective in a real-world setting of severe neuropathic cancer pain, with a high rate of satisfaction, without interference on bowel function

A Psychometric Properties Evaluation of the Italian Version of the Geriatric Depression Scale

Objective. The Geriatric Depression Scale (GDS) is an evaluation tool to diagnose older adult's depression. This questionnaire was defined by Yesavage and Brink in 1982; it was designed expressly for the older person and defines his/her degree of satisfaction, quality of life, and feelings. The objective of this study is to evaluate the psychometric properties of the Italian translation of the Geriatric Depression Scale (GDS-IT). Methods. The Italian version of the Geriatric Depression Scale was administered to 119 people (79 people with a depression diagnosis and 40 healthy ones). We examined the following psychometric characteristics: internal consistency reliability, test-retest reliability, concurrent validity, and construct validity (factor structure). Results. Cronbach's Alpha for the GDS-IT administered to the depressed sample was 0.84. Test-retest reliability was 0.91 and the concurrent validity was 0.83. The factorial analysis showed a structure of 5 factors, and the scale cut-off is between 10 and 11. Conclusion. The GDS-IT proved to be a reliable and valid questionnaire for the evaluation of depression in an Italian population. In the present study, the GDS-IT showed good psychometric properties. Health professionals now have an assessment tool for the evaluation of depression symptoms in the Italian population

The wheelchair use confidence scale: italian translation, adaptation, and validation of the short form

Objective: We developed an Italian version of the Wheelchair Use Confidence Scale for Manual Users- Short Form (WheelCon-M-I-short form) and examined its reliability and validity. Methods: The original scale was translated from English to Italian using the “Translation and Cultural Adaptation of Patient Reported Outcomes Measures–Principles of Good Practice” guidelines. The WheelCon-M-I-short form was administered to experienced manual wheelchair users who had a variety of diagnoses. Its internal consistency and test–retest reliability were examined. Its concurrent validity was evaluated using Pearson correlation coefficients with the Italian version of the Wheelchair Outcome Measure (WhOM-I) and the Italian version of the Barthel index (BI). Results: The WheelCon-M-I-short form was administered to 31 subjects. The mean ± SD of the WheelCon- M-I-short form score was 7.5±1.9. All WheelCon-M-I-short form items were either identical or similar in meaning to the WheelCon-M-short form items. Cronbach’s a for the WheelCon-M-I-short form was 0.95 (p&lt;0.01), and the test–retest reliability (ICC) was 0.978 (p&lt;0.01). The Pearson correlation coefficient of the WheelCon-M-I-short form scores with the WhOM-I scores was 0.7618 (p&lt;0.01). The Pearson correl- ation coefficient of the WheelCon-M-I-short form scores with the Italian BI scores was 0.638 (p &lt; 0.01). Conclusions: The WheelCon-M-I-short form was found to be reliable and a valid outcome measure for assessing manual wheelchair confidence in the Italian population

Effect of different lignocellulosic fibres on poly(ε-caprolactone)-based composites for potential applications in orthotics

This work compares the mechanical and thermal behaviour of fully biodegradable biocomposites based on polycaprolactone reinforced with three different natural fibres, namely hemp, sisal and coir, for potential applications in the field of orthoses. The same properties were further compared to those of two commercially available materials commonly used in the same prospective field. The results confirmed that the addition of natural fibres, irrespective of the origin of the fibres (leaf, bast or fruit) to a biodegradable matrix allows for significant improvement of the mechanical behaviour of the ensuing composites compared to traditional thermoplastic materials used in orthotics

Health systems sustainability in the framework of rare diseases actions. Actions on educational programmes and training for professionals and patients

Protection of early development contributes to health of next generations. Congenital anomalies (and other adverse reproductive outcomes) are an important public health issue and early indicator of public health risks, as early development is influenced by many risk factors (e.g., nutrition, lifestyles, pollution, infections, medications, etc). Effective primary prevention requires an integrated “One Health” approach, linking knowledge  and action. This requires surveillance of health events and potential health-damaging factors, science-based risk analysis, citizens’ empowerment and education of health professionals. From the policy standpoint, joint budgeting mechanisms are needed to sustain with equity intersectoral actions (involving policy domains of health, social affairs, education, agriculture and environment). States should devote resources to strengthen registries and systematic data collection for surveillance of congenital anomalies, to better inform national prevention strategies. Investing in primary prevention based on scientific evidence is essential to support sustainable and resilient health systems and sustainable development of the society

Immunophenotyping of leukocytes in bovine placenta

Lymphocytes and macrophages are the main white cells involved in fetal-maternal tolerance. Little is known about these leukocytes in bovine placenta, such as the quantity and location of these cells. Thus, the objective of this study was to identify lymphocyte and macrophage populations in bovine placenta using specific markers and flow cytometry. This study analyzed samples of placentomes and intercaruncular regions of cows in the three quarters of pregnancy. In the placentomes, during the first quarter of pregnancy, mean percentage of labeled CD3+ cells was 2.34%; CD8+, 1.28%; CD14+, 1.66%; and CD335+, 0.96%. For the intercaruncular region, percentage of CD3+ cells was 0.71%; CD8+, 1.63%; CD14+, 2.81%; and CD335+, 2.81%. In the second quarter, placentomes showed 0.94% CD3+ cells; 0.77% CD8+; 0.72% CD14+; and 0.51% CD335+. In the intercaruncular region, percentage of labeled CD3+ cells was 0.50%; CD8+, 1.81%; CD14+, 2.64%; and CD335+, 0.51%. In the third quarter, placentomes showed labeling of 0.88% CD3+; 0.66% CD8+; 1.06% CD14+; and 0.74% CD335+ cells. In the intercaruncular region, percentage of labeled CD3+ cells was 0.19%; CD8+, 2.23%; CD14+, 2.43%; and CD335+, 0.16%. The results showed that there was a greater immunomarking of leukocytes CD3+ and CD335+ in the placentome when compared to the intercaruncular region during the third trimester. It can be concluded that leukocytes populations in bovine placenta is reduced, probably because of the syndesmochorial characteristic of bovine placenta. This represents a significant barrier for the immunological system of the mother, sharply decreasing the exposure of the conceptus to the mother’s immune system.Linfócitos e macrófagos são os principais leucócitos envolvidos na tolerância materno-fetal. Pouco se sabe sobre esses leucócitos na placenta bovina, como por exemplo, a quantidade e localização dessas células. Assim, o objetivo desse estudo foi identificar populações de linfócitos e macrófagos na placenta bovina utilizando marcadores específicos e citometria de fluxo. Este estudo analisou amostras de placentônios da região intercaruncular de bovinos nos três trimestres da gestação. No primeiro trimestre, nos placentônios, a porcentagem média de células CD3+ foi 2,34%; CD8+, 1,28%; CD14+, 1,66%; e CD335+, 0,96%. Na região intercaruncular, a porcentagem de células CD3+ foi 0,71%; CD8+, 1,63%; CD14+, 2,81%; e CD335+, 2,81%. No segundo trimestre, os placentonios apresentaram 0,94% de células CD3+; 0,77% de CD8+; 0,72% de CD14+e 0,51% de CD335+. Na região intercaruncular, a porcentagem de células CD3+ foi 0,50%; CD8+, 1,81%; CD14+, 2,64%; e CD335+, 0,51%. No terceiro trimestre, os placentônios apresentaram 0,88% de células marcadas CD3+; 0,66% de CD8+; 1,06% de CD14+ e 0,74% de CD335+. Na região intercaruncular, a porcentagem de células CD3+ foi 0,19%; CD8+, 2,23%; CD14+, 2,43% e CD335+, 0,16%. Os resultados mostraram que a imunomarcação de leucócitos na região do placentônio foi maior do que na região intercaruncular no terceiro trimestre. Concluiu-se que a população de leucócitos CD3+ e CD335+ na placenta bovina está reduzida, provavelmente devido a sua característica sindesmocorial. Essa característica representa uma barreira significante para o sistema imunológico da mãe, o que diminui drasticamente a exposição do concepto ao sistema de defesa da mãe

Sustainable public health systems for rare diseases

In the framework of the Joint Action for Rare Diseases (RD-ACTION), a specific task was defined to identify mechanisms influencing sustainability, equity and resilience of health systems for rare diseases (RDs).Method: literature narrative review on health systems sustainability and resilience for RDs. Years: 2000-2015. Databases: PubMed, Scopus, EBSCOHost, EMBAL, PASCAL, EMBASE, STN International and GoogleScholar. Analysis: interpretive synthesis concept and thematic analysis (Dixon-Wood et al.)Results: 97 papers and 4 grey literature publications were identified. Two main topics stand out: economic evaluation and networks. The first topic did not identify widely accepted criterion to assign more weight to individuals with greater health needs. Healthcare network are identified as increasingly important for sustainability and resilience, in all of their aspects: professional (‘expertise’), ‘experience’ networks of users and carers; policy, learning, and interest networks.In conclusion, possible mechanisms for ensuring sustainability can be identified in networking, patients’ empowerment and reorienting healthcare towards integrated community and home care

Tumor-infiltrating B lymphocytes as an efficient source of highly specific immunoglobulins recognizing tumor cells

<p>Abstract</p> <p>Background</p> <p>There is much evidence that tumor cells elicit a humoral immune response in patients. In most cases, the presence of antibodies in peripheral blood is detected only in small proportion of patients with tumors overexpressing the corresponding antigen. In the present study, we analyzed the significance of local humoral response provided by tumor-infiltrating lymphocytes in breast cancer patients.</p> <p>Methods</p> <p>The ability of a patient's immune system to produce specific antibodies inside tumor tissue, capable of recognizing tumor cells, was explored through analysis of the oligoclonality of antibodies derived from tumor-infiltrating lymphocytes and construction of a series of recombinant antibody libraries in scFv format, derived from breast tumor-infiltrating B lymphocytes. These libraries and one from peripheral blood lymphocytes of a single breast cancer patient were panned against three purified surface tumor antigens, such as CEA, MUC1 and ED-B domain, and against intact MCF7 breast carcinoma cells.</p> <p>Results</p> <p>Application of novel display vector, pKM19, allowed isolation of a large panel of breast cancer-specific antibodies against known tumor antigens, as well as against breast carcinoma cells. Reactivity of novel scFvs was confirmed by ELISA, immunohistochemistry, fluorescence staining and flow cytometry. We demonstrated that seven of ten primary breast tumor specimens, obtained using discarded surgical material, could be exploited as an appropriate source for generation of phage display libraries, giving highly specific antitumor antibodies which recognize heterologous tumor cells.</p> <p>Conclusion</p> <p>Local humoral immune response within tumor tissue in breast cancer patients frequently has an oligoclonal character. Efficient selection of specific antitumor antibodies from recombinant antibody libraries, derived from such oligoclonal tumor-infiltrated B lymphocytes, indicates the presence of natural immune response against tumor antigens in these patients. The described method is very promising for development of antitumor antibodies, potentially useful for diagnostic and therapeutic approaches.</p
