French adaptation of the "Frenchay Dysarthria Assessment 2" speech intelligibility test.

OBJECTIVES: Speech intelligibility can be defined as "the degree to which a speaker's intended message is recovered by a listener". Loss of intelligibility is one of the most frequent complaints in patients suffering from speech disorder, impairing communication. Measurement of intelligibility is therefore an important parameter in follow-up. We developed a French version of the "Frenchay Dysarthria Assessment, 2nd edition" (FDA-2), an intelligibility test recognized internationally in its English version. The present study details the construction of the test and its preliminary validation. MATERIALS AND METHODS: We first compiled a set of words and phrases in French, based on the criteria defined in FDA-2. In a second step, we validated the test in healthy subjects in normal and noisy conditions, to check sensitivity to speech signal degradation. RESULTS: The test proved valid and sensitive, as scores were significantly lower for noise-degraded stimuli. CONCLUSION: This French-language intelligibility test can be used to evaluate speech disorder: for example, in dysarthria, head and neck cancer or after cochlear implantation.

Developmental care, neonatal behavior and postnatal maternal depressive symptomatology predict internalizing problems at 18 months for very preterm children.

OBJECTIVE: To provide a prospective developmental model for behavioral outcomes in preterm infants in relation to developmental care (DC) practices and postnatal maternal depression. STUDY DESIGN: A longitudinal, multicenter, follow-up study conducted in 25 Italian tertiary neonatal intensive care units (NICUs). Participants were 162 healthy very preterm infants and their mothers. The level of quality of DC was assessed for each hospital. Infant's neurobehavioral profile was evaluated twice: at discharge (T1) and at 18 months for behavioral problems (T3). Maternal depressive symptomatology was measured at T1 and at 6 months (T2). RESULTS: Low-quality DC in NICUs was associated with lower levels of infant neurobehavioral adaptability and higher levels of maternal depressive symptoms. Maternal depressive symptomatology in conjunction with higher infant dysregulation predicted more internalizing problems at 18 months of age. CONCLUSION: DC interventions and postnatal maternal depression, as well as infant behavior have an impact on short- and long-term infant outcomes.

Moderate Depression Promotes Posttraumatic Growth (Ptg): A Young Population Survey 2 Years after the 2009 L'Aquila Earthquake.

BACKGROUND: Earthquakes can result in a range of psychopathology and in negative and positive consequences for survivors. OBJECTIVE: To examine the association between clinical aftereffects (anxiety and depressive symptoms) and post-traumatic growth (PTG) among young survivors of the 2009 L'Aquila earthquake, Italy. METHOD: 316 young earthquake survivors enrolled in the University of L'Aquila were evaluated two years after the natural disaster. Participants completed three main questionnaires, including Patient Health Questionnaire-9 items (PHQ-9), Self-Rating Anxiety Scale (SAS), and Posttraumatic Growth Inventory (PTGI). RESULTS: 59.6% of the student sample showed different levels of depression, whereas 13.3% reported anxiety symptoms. In both clinical dimensions (anxiety and depression), gender differences were found: female gender was confirmed risk factor for a clinical post-traumatic response. Personal PTG, demonstrated by 18% of the L'Aquila youths included in our sample, was predicted by moderate levels of depression (O.R. 2.7). In our model, gender, age, and anxiety did not show any predictive value. CONCLUSION: In a post-traumatic setting, the development of individual cognitive strategies is crucial, whereas after a natural disaster, paradoxically, a moderate depressive condition and the related distress could promote the drive to overcome the psychological consequences of the traumatic event.

A Novel Panel of Serum Biomarkers for MPM Diagnosis.

Exposure to asbestos is the main cause of malignant pleural mesothelioma (MPM), a highly aggressive cancer of the pleura. Since the only tools for early detection are based on radiological tests, some authors focused on serum markers (i.e., mesothelin). The aim of this study was the evaluation of new serum biomarkers to be used individually or in combination, in order to improve the outcome of patients whose disease would be diagnosed at an earlier stage. Serum and plasma were available from 43 subjects previously exposed to asbestos and 27 MPM patients, all being epithelioid type. All the new markers found differentially expressed in MPM and healthy subjects, by proteomic and genomic approaches, have been validated in the serum by the use of specific ELISA. The combined approach, using tools of genomics and proteomics, is found to be highly innovative for this type of disease and led to the identification of new serum markers in the diagnosis of MPM. These results, if confirmed in a larger series, may have a strong impact in this area, because early detection of this cancer in people at high risk could significantly improve the course of the disease and the clinical approach to an individualized therapy.

Bottom-up proteomics suggests an association between differential expression of mitochondrial proteins and chronic fatigue syndrome.

Chronic fatigue syndrome (CFS) is a debilitating and complex disorder characterized by unexplained fatigue not improved by rest. An area of investigation is the likely connection of CFS with defective mitochondrial function. In a previous work, we investigated the proteomic salivary profile in a couple of monozygotic twins discordant for CFS. Following this work, we analyzed mitochondrial proteins in the same couple of twins. Nano-liquid chromatography electrospray ionization mass spectrometry (nano-LC-MS) was used to study the mitochondria extracted from platelets of the twins. Subsequently, we selected three proteins that were validated using western blot analysis in a big cohort of subjects (n=45 CFS; n=45 healthy), using whole saliva (WS). The selected proteins were as follows: aconitate hydratase (ACON), ATP synthase subunit beta (ATPB) and malate dehydrogenase (MDHM). Results for ATPB and ACON confirmed their upregulation in CFS. However, the MDHM alteration was not confirmed. Thereafter, seeing the great variability of clinical features of CFS patients, we decided to analyze the expression of our proteins after splitting patients according to clinical parameters. For each marker, the values were actually higher in the group of patients who had clinical features similar to the ill twin. In conclusion, these results suggest that our potential markers could be one of the criteria to be taken into account for helping in diagnosis. Furthermore, the identification of biomarkers present in particular subgroups of CFS patients may help in shedding light upon the complex entity of CFS. Moreover, it could help in developing tailored treatments.

Language outcomes at 36 months in prematurely born children is associated with the quality of developmental care in NICUs.

OBJECTIVE: The aim of this study was to examine the relationship between the quality levels of NICU developmental care (DC) and language skills at 36 months in very preterm (VPT) children. STUDY DESIGN: Language skills of 78 VPT children from 19 NICUs and 90 full-term controls was assessed using a standardized language test. We compared children' language task performance by splitting NICUs into units with high- and low-quality of DC according to two main factors: (1) infant centered care (ICC), and (2) infant pain management (IPM). RESULTS: VPT children from low-care units with respect to ICC obtained lower scores in sentence comprehension, compared to children from high-care units. No differences were found between preterm children from high-quality ICC NICUs and full-term children. CONCLUSIONS: Findings suggest that higher quality of DC related to infant centered care can mitigate delays in language skills at 36 months in children born VPT.

Adjustment to cancer: exploring patients' experiences of participating in a psychodramatic group intervention.

The main purpose of the present study was to understand the subjective experience of patients adjusting to cancer by focusing on how that experience might be affected by participating in a psychodramatic group intervention. In-depth interviews using an interpretative-phenomenological approach were conducted with eight cancer patients involved in a psychodrama group. Four key themes were identified: (1) outside and inside relationships; (2) identities: nurturing other selves; (3) a feelings' gym: performing the internal world; and (4) many ends: mourning death and dying. Participation in cancer group using a psychodramatic approach provided positive results. In detail, the group setting: (1) favoured relationships in which it was possible to freely express oneself and (2) empowered patients in their feelings of being able to give and receive help; the psychodramatic approach: (1) supported the physical mobilisation of sense of agency and (2) permitted to deal with the grieving process. Cancer healthcare pathways would benefit from psychotherapeutic programmes using a similar approach, since psychodrama by actively involving body seems to works on areas that are often underwhelmed by other approaches, such as (i.e., physical mobilisation, body engagement, grieving adjustment). Psychodrama supports patients to achieve insights into their own possibilities to actively participate in their own life situations despite having cancer and undergoing treatment for it.

PTSD Growth and Substance Abuse Among a College Student Community: Coping Strategies after 2009 L'aquila Earthquake.

Aim of the study was the assessment of coping strategies, specifically substance use and post-traumatic growth (PTG), in 411 college students two years after 2009 L'Aquila earthquake. Post-Traumatic Growth Inventory (PTGI) was used to assess PTG and one question about substance use (alcohol, tobacco, cannabis) was asked to verify if students had modified their use in the post-earthquake compared with the pre-earthquake period. The 77.1% of college students were exposed to L'Aquila earthquake. The PTGI mean score was 35.23, underlining low positive coping strategies among student community. About substance abuse, the 43.8% of college students reported a marked increase in alcohol use, 7.8% in cannabis and the 15.8% reported an increase in nicotine use in the post-earthquake period. Despite these data, 12.5 % of the students reported a decrease in alcohol use after the earthquake and 17.3% of the sample reported a PTG, showing positive behaviors and attitudes after the traumatic experience of the natural disaster (increase of social relationships, appreciation of new future possibilities, and development of a new deep meaning of life). Inferential analysis shows a strong negative correlation between direct earthquake exposure and PTGI total score. In post-disaster settings, a systematic framework of case identification, triage, and mental health interventions, including the improvement of positive coping strategies, like the PTG, should be integrated into emergency medicine and trauma care responses.

[Psychotropic-associated sexual dysfunctions: a survey of clinical pharmacology and medication-associated practice]. / Disfunzioni sessuali associate all'uso di farmaci psicotropi: una revisione per la pratica clinica quotidiana.

Epidemiological and clinical studies show that often persons affected by depression and schizophrenia can suffer of impairment of the sexual function. Most antidepressant and antipsychotic drugs have adverse sexual effects but it is difficult to identify if the impairment of the sexual function can be attributed to clinical picture or to the psychopharmacological treatments. Both antidepressants and novel and conventional antipsychotics are associated with significant sexual side effects and the presence of sexual side effects may affect compliance and adherence to treatment. In some specific clinical populations (e.g. youths), these specific side-effects turn out to be one of the most annoying and promote increased drop-out rates and poor adherence to treatment. Nevertheless, these clinical variables are often underestimated or not investigated in the course of follow-up of persons suffering from psychiatric disorders in treatment with psychotropic medications. Growing awareness of the adverse effects of psychotropic drugs has led to attempts to use adjuvants or substitute treatments to resolve sexual dysfunction. Effects on sexual function should be carefully diagnosed and treated; it should clearly discuss with patients in order to preserve an adequate quality of life, promote greater adherence to treatment and promote a good remission and recovery. The aim of this study is to review the most recent and significant literature data regarding association between sexual dysfunction and psychotropic medications, especially highlighting neurobiological and clinical data in order to improve the clinical pratice.

The activation of mitochondrial BK potassium channels contributes to the protective effects of naringenin against myocardial ischemia/reperfusion injury.

Naringenin (NAR), flavonoid abundant in the genus Citrus, has been reported to interact with the large-conductance calcium-activated potassium channels (BK). Since activators of BK channels expressed in cardiac mitochondria trigger protective effects in several models of myocardial ischemia/reperfusion (I/R), this work aimed to evaluate the potential cardioprotective effects of NAR and the involvement of mitochondrial BK channels. In an in vivo model of acute infarct in rats, NAR (100mg/kg i.p.) significantly reduced the heart injury induced by I/R. This effect was antagonized by the selective BK-blocker paxilline (PAX). The cardioprotective dose of NAR did not cause significant effects on the blood pressure. In Largendorff-perfused rat hearts submitted to ischemia/reperfusion, NAR improved the post-ischemic functional parameters (left ventricle developed pressure and dP/dt) with lower extension of myocardial injury. On isolated rat cardiac mitochondria, NAR caused a concentration-dependent depolarization of mitochondrial membrane and caused a trans-membrane flow of thallium (potassium-mimetic cation). Both these effects were antagonized by selective blockers of BK channels. Furthermore, NAR half-reduced the calcium accumulation into the matrix of cardiac mitochondria exposed to high calcium concentrations. In conclusion, NAR exerts anti-ischemic effects through a "pharmacological preconditioning" that it is likely to be mediated, at least in part, by the activation of mitochondrial BK channels.

The chemistry and parent material of urban soils in Bristol (UK): implications for contaminated land assessment.

An earlier survey of topsoil from parks and allotment in the city of Bristol (UK) revealed the presence of relatively high levels of "pseudo-total" Cd, As, Cu, Pb and Zn, with Cd and As exceeding present UK soil guidelines. This follow-up work aimed at (1) estimating geochemical thresholds for these elements based on "near-total" soil, bedrock and sediment heavy metals and (2) determining the genetic relationship between soil and bedrock using rare earth elements (REEs or lanthanides) as tracers. "Near-total" concentration of 34 elements (Al, Ca, Fe, K, Mg, Na, As, Ba, Cd, Cr, Cu, Li, Mn, Ni, P, Pb, Sc, Ti, V, Zn, Y and the rare earth elements Ce, Dy, Er, Eu, Gd, Ho, La, Lu, Nd, Pr, Sm, Tb, Yb) were obtained by ICP-MS and ICP-OES. The results show that the soil composition is largely controlled by the soil parent material, though extreme outliers are indicative of contamination at a few sites of parkland and allotments. Cumulative frequency plots show the presence of different data sets for which separate "background" values should be determined. The REE data provide evidence that weathering of the underlying sandstone was a determinant factor leading to the relatively high heavy metal enrichment found in soil samples and sediments. Reference to UK soil guidelines to decide on possible remediation measures could be very misleading due to the natural high background levels of some elements in the underlying bedrock. Before defining land as "contaminated", a thorough geochemical investigation is required at local scale in order to produce a more realistic and correct environmental assessment.

[MALDI-TOF and SELDI-TOF analysis: "tandem" techniques to identify potential biomarker in fibromyalgia]. / MALDI-TOF e SELDI-TOF: due tecniche "tandem" per l'individuazione di potenziali biomarker nella fibromialgia.

OBJECTIVE: Fibromyalgia (FM) is characterized by the presence of chronic widespread pain throughout the musculoskeletal system and diffuse tenderness. Unfortunately, no laboratory tests have been appropriately validated for FM and correlated with the subsets and activity. The aim of this study was to apply a proteomic technique in saliva of FM patients: the Surface Enhance Laser Desorption/Ionization Time-of-Flight (SELDI-TOF). METHODS: For this study, 57 FM patients and 35 HC patients were enrolled. The proteomic analysis of saliva was carried out using SELDI-TOF. The analysis was performed using different chip arrays with different characteristics of binding. The statistical analysis was performed using cluster analysis and the difference between two groups was underlined using Student's t-test. RESULTS: Spectra analysis highlighted the presence of several peaks differently expressed in FM patients compared with controls. The preliminary results obtained by SELDI-TOF analysis were compared with those obtained in our previous study performed on whole saliva of FM patients by using electrophoresis. The m/z of two peaks, increased in FM patients, seem to overlap well with the molecular weight of calgranulin A and C and Rho GDP-dissociation inhibitor 2, which we had found up-regulated in our previous study. CONCLUSION: These preliminary results showed the possibility of identifying potential salivary biomarker through salivary proteomic analysis with MALDI-TOF and SELDI-TOF in FM patients. The peaks observed allow us to focus on some of the particular pathogenic aspects of FM, the oxidative stress which contradistinguishes this condition, the involvement of proteins related to the cytoskeletal arrangements, and central sensibilization.

Stability and efficiency of biofilms for landfill leachate treatment.

The objective of this work was to assess the feasibility of a fixed-film biological aerated filtration process for the treatment of the leachate produced at Harnhill landfill site (South Gloucestershire, UK). The laboratory scale plant consisted of four identical biological aerated filters (a triplicate and a "control" column) packed with small brick fragments. Biofilm formed within 24h of immersion of the support material in the reactor, and had a high resistance to antibiotics and other toxic agents. The plant maintained a stable operation in the 20-45 degrees C temperature range, showing the best results (35.4+/-6.6% COD removal and 73.9+/-5.5% BOD(5) reduction) at 40 degrees C. The lowest COD and BOD(5) values obtained at the outlet of the columns were 7067 mg/L and 1050 mg/L, respectively.

A review of waste management practices and their impact on human health.

This work reviews (i) the most recent information on waste arisings and waste disposal options in the world, in the European Union (EU), in Organisation for Economic Co-operation and Development (OEDC) countries, and in some developing countries (notably China) and (ii) the potential direct and indirect impact of waste management activities on health. Though the main focus is primarily on municipal solid waste (MSW), exposure to bioaerosols from composting facilities and to pathogens from sewage treatment plants are considered. The reported effects of radioactive waste are also briefly reviewed. Hundreds of epidemiological studies reported on the incidence of a wide range of possible illnesses on employees of waste facilities and on the resident population. The main conclusion of the overall assessment of the literature is that the evidence of adverse health outcomes for the general population living near landfill sites, incinerators, composting facilities and nuclear installations is usually insufficient and inconclusive. There is convincing evidence of a high risk of gastrointestinal problems associated with pathogens originating at sewage treatment plants. In order to improve the quality and usefulness of epidemiological studies applied to populations residing in areas where waste management facilities are located or planned, preference should be given to prospective cohort studies of sufficient statistical power, with access to direct human exposure measurements, and supported by data on health effect biomarkers and susceptibility biomarkers.

The veterinary food hygienist in the food industry: contextual analysis and perspectives.

After an introduction concerning the structure of Italian and European Veterinary Offices, the authors outline the features of food production in the provinces of Parma and Reggio Emilia, particularly concerning the role of veterinary hygienists and of the other professionals operating along the food chain. The authors underline that veterinarians should improve their managerial skills, together with the technical and legal competences acquired during the bachelor course, (eventually integrated by stages in food factories) and undertake continuous post-university improvement, enabling them to face the competition presented by new professionals.

Proteomic analysis of human thyroid fine needle aspiration fluid.

The aim of this study was to determine the protein pattern of human thyroid fine needle aspiration fluid (FNA) using a proteomic approach. FNA proteins were separated using 2-dimensional gel electrophoresis (2DE), digested and then analyzed by peptide mass fingerprinting. For the first time, we provided an image of the protein components of the FNA, in which approximately 220 protein spots can be identified. The proteome analysis revealed a specific fingerprint of FNA with proteins appertaining to various functional systems. Our preliminary results of FNA protein pattern could be a starting point in studying the presence of potential markers implicated in thyroid diseases.

K-->pipi amplitudes from lattice QCD with a light charm quark.

We compute the leading-order low-energy constants of the DeltaS=1 effective weak Hamiltonian in the quenched approximation of QCD with up, down, strange, and charm quarks degenerate and light. They are extracted by comparing the predictions of finite-volume chiral perturbation theory with lattice QCD computations of suitable correlation functions carried out with quark masses ranging from a few MeV up to half of the physical strange mass. We observe a DeltaI=1/2 enhancement in this corner of the parameter space of the theory. Although matching with the experimental result is not observed for the DeltaI=1/2 amplitude, our computation suggests large QCD contributions to the physical DeltaI=1/2 rule in the GIM limit, and represents the first step to quantify the role of the charm-quark mass in K-->pipi amplitudes. The use of fermions with an exact chiral symmetry is an essential ingredient in our computation.

Natural and anthropogenic contamination of the Fratta-Gorzone river (Veneto, Italy).

Stream-bed sediment samples were collected in 2001 and 2004 along the Fratta-Gorzone River (Italy) to assess the level of heavy metal contamination. The river stretch most affected by discharges of tannery effluent showed total and pseudo-total Cr levels (up to 2,860 mg/kg) that greatly exceed national and international chemical sediment quality standards. The most contaminated section of the river bed is located downstream of the main industrial discharge. However, a large fraction of the Cr present in the sediment appears to be of lithogenic origin. At most sites, more than 50% of Cr is not soluble in aqua-regia and thus unlikely to be very mobile or easily bio-available. A negligible risk to the benthic community can be inferred for Pb, Zn, Cd, Cu and Ni. This work highlights the limitation of using existing chemical sediment quality standards alone for risk assessment. The collection and analysis of suspended solids, the determination of river discharge and of dissolved Cr at 10 field stations allowed to estimate the particulate and dissolved Cr load and to locate the river stretch that was the likely source of contaminated sediment. The pumping of dilution water from the Adige River into the Fratta-Gorzone River did not produce the expected contaminant dilution effect due to re-suspension of contaminated solid particles and the release of Cr in solution.
