Abnormalities in the processing of emotional prosody from single words in schizophrenia

Background: Abnormalities in emotional prosody processing have been consistently reported in schizophrenia and are related to poor social outcomes. However, the role of stimulus complexity in abnormal emotional prosody processing is still unclear. Method: We recorded event-related potentials in 16 patients with chronic schizophrenia and 16 healthy controls to investigate: 1) the temporal course of emotional prosody processing; and 2) the relative contribution of prosodic and semantic cues in emotional prosody processing. Stimuli were prosodic single words presented in two conditions: with intelligible (semantic content condition—SCC) and unintelligible semantic content (pure prosody condition—PPC). Results: Relative to healthy controls, schizophrenia patients showed reduced P50 for happy PPC words, and reduced N100 for both neutral and emotional SCC words and for neutral PPC stimuli. Also, increased P200 was observed in schizophrenia for happy prosody in SCC only. Behavioral results revealed higher error rates in schizophrenia for angry prosody in SCC and for happy prosody in PPC. Conclusions: Together, these data further demonstrate the interactions between abnormal sensory processes and higher-order processes in bringing about emotional prosody processing dysfunction in schizophrenia. They further suggest that impaired emotional prosody processing is dependent on stimulus complexity.

Abnormal interactions between context, memory structure, and mood in schizophrenia: an ERP investigation

This study used event-related potentials to examine interactions between mood, sentence context, and semantic memory structure in schizophrenia. Seventeen male chronic schizophrenia and 15 healthy control subjects read sentence pairs after positive, negative, or neutral mood induction. Sentences ended with expected words (EW), within-category violations (WCV), or between-category violations (BCV). Across all moods, patients showed sensitivity to context indexed by reduced N400 to EW relative to both WCV and BCV. However, they did not show sensitivity to the semantic memory structure. N400 abnormalities were particularly enhanced under a negative mood in schizophrenia. These findings suggest abnormal interactions between mood, context processing, and connections within semantic memory in schizophrenia, and a specific role of negative mood in modulating semantic processes in this disease.

Qualidade de vida de pacientes hipertensos em tratamento ambulatorial

FUNDAMENTO: As doenças cardiovasculares são principal causa de mortalidade na população brasileira, sendo a hipertensão arterial (HA) de maior prevalência. A terapêutica para o tratamento da HA é cada vez maior e sabe-se que melhora a sobrevida dos pacientes, porém questiona-se a melhora na qualidade de vida (QV) do paciente hipertenso após tratamento. OBJETIVO: Comparar aspectos relacionados à QV de pacientes hipertensos em tratamento. MÉTODOS: Foram estudados 100 pacientes hipertensos; 46 aderidos a um esquema de tratamento padrão (grupo A) e 54 (grupo B controle) que iniciariam este esquema. Colheu-se dados clínicos e sócio-demográficos, realizou-se questões com enfoque na sexualidade, auto-percepção da QV, número e tipo de medicamentos utilizados e sua interferência na vida sexual e aplicou-se o questionário SF-36. Submeteram-se os resultados à análise estatística comparativa utilizando-se testes: t de Student, qui-quadrado, coeficiente de correlação de Pearson e Tukey. RESULTADOS: Não houve diferença estatística entre os grupos para nenhum domínio do SF-36. Houve associação entre a questão da auto-percepção da QV e os domínios do SF-36, exceto nos aspectos emocionais. Na questão com enfoque na sexualidade, encontrou-se diferença quanto à QV sexual entre os grupos, sendo menos satisfatória para o grupo A. CONCLUSÃO: Quando aplicado o SF-36, não detectou-se modificações na QV entre os grupos por tratar-se de doença crônica assintomática. Este questionário não avaliou adequadamente os aspectos emocionais dos hipertensos na nossa casuística com grande variabilidade comportamental. A QV sexual foi menos satisfatória no grupo A, entretanto não encontrou-se relacionada ao número e tipo da medicação anti-hipertensiva utilizada.

Silent voices : the recreational needs of disabled young people : an emancipatory approach

The recreational needs of young people with.disabilities in Sligo county were examined using an emancipatory approach that provided an accurate reflection on the perspectives of the disabled young people. The aim of this study included a comparison of access to and attitudes towards leisure activities as between disabled and non-disabled young people in the Sligo area. The hypothesis set out by the researcher was the expectation that findings would include a degree of disadvantage in access and participation in leisure activities for young people with disabilities vis a vis their counterparts. The way in which this was tested was by focus groups and interviews. This hypothesis was adequately proven along with an in-depth range of recommendations for improvement that were made by participants. The study’s emancipatory research methods ensured that the voice of the participants was heard regarding their recreational needs and the disabling barriers that needed to be removed.

Groundwater vulnerability and protection in County Tipperary (South Riding), Ireland

The aim of the project was to determine the extent and quality of the groundwater in Tipperary South Riding with a view to developing a groundwater protection plan which would allow the Local Authority to manage, protect and develop the groundwater as efficiently as possible. The geology of the area varies with topography. The low-lying areas of the county comprise mainly Carboniferous limestones while the elevated regions consist of sandstones and shales of Upper Carboniferous, Devonian and Silurian ages. Deformation of these rocks decreases in magnitude moving northwards over the area; the Southern Synclines having suffered the effects of the Hercynian orogeny and the northern region exhibiting Caledonian orogenic trends. Quaternary (subsoil) deposits are found throughout the area and are of variable thickness and permeability. Till is the most widespread deposit with discontinuous pockets of sand and gravel in various proportions, and some marl, alluvium and peat in places. The principal aquifers of the area are the Kiltorcan sandstone formation and various limestone units within the Carboniferous succession. 50 % of south Tipperary constitutes either regionally or locally important aquifers. Secondary permeabilities created by structural deformation, dolomitisation, karstification and weathering processes create high transmissivities and often have large well yields. Specific baseflow analysis highlighted the complexity of the aquifers and proved that the lower part of the Suir river system is a major groundwater resource region. The hydrochemistry and water quality of the local authority groundwater sources was examined briefly. The majority of south Tipperary is underlain by limestone or Quaternary deposits derived from limestone and, consequently, calcium/magnesium bicarbonate waters predominate. The quality of the groundwater in south Tipperary demonstrates that the main concern originates from the presence of E.coli, and Total coliforms. The primary sources of contamination are from farmyard wastes and septic tanks. The vulnerability of groundwater to diffuse and point sources of pollution has been found to be dependent on the overlying soil, subsoil and the thickness of the unsaturated zone. A conceptual rather than quantitative approach is used and it is found that approximately 60% of south Tipperary is designated as being extremely or highly vulnerable. The groundwater protection plan was devised subsequent to an understanding of the aquifer systems, an assessment of the vulnerability, and a review of the Irish planning system and environmental law. It is recommended that the plan be integrated into the county development plan for legislative purposes. A series of acceptability matrices were devised to restrict potentially polluting activities in vulnerable areas while maintaining a balance between protection of the groundwater resource and the need to site essential developments.

Does the provision of full day care improve the quality of life for children and their parents

This study sought to explore and examine if the provision of full day care improves the quality of life for children and their parents. Owing to the effects of the Celtic Tiger, life in Ireland has changed considerably over the past five to ten years. Because of the booming economy there are now 60.8% of women employed in the workforce. This means many changes for children, parents and families. Findings in the literature review are based on international studies. The researcher utilised both qualitative and quantitative research methodologies for the study. She interviewed 31 respondents; 27 childcare managers; 3 politicians and the chairperson of a childcare committee. Furthermore, 325 questionnaires were completed in a survey by working parents in the statutory and voluntary sectors in and around Sligo town and in two childcare facilities in Letterkenny, Co. Donegal. Babies as young as 4 months are being cared for in childcare facilities from 6.45am until 6.pm daily, 5 days per week. Some children are spending up to 11 hours per day in childcare facilities. The study has not categorically concluded that full day care is either positive or negative for children. Childcare facilities are providing good quality childcare encompassing various services; however, 25 out of 27 childcare managers reported to the researcher that they would not leave their child in full day care. Parents are finding it difficult to manage work life balance. Health dominated quality of life issues. Two hundred and thirty five (235) parents reported being stressed. The study also found that 315 working parents feel that the government is not doing enough to support working parents. On a positive note, 241 parents said they are happy in general with the quality of life for them, their family and their children. In addition, the researcher has identified a number of recommendations for future changes in policy and further study.
