Promoting reminiscences with virtual reality headsets: A pilot study with people with dementia

This study aimed to explore the feasibility and effects of promoting reminiscences, using virtual reality (VR) headsets for viewing 360° videos with personal relevance, with people with dementia. A study with a mixed methods design was conducted with nine older adults diagnosed with dementia. Interventions consisted of four sessions, in which the participants’ engagement, psychological and behavioral symptoms, and simulation sickness symptoms were evaluated. Neuropsychiatric symptomatology and quality of life were measured pre- and post-intervention. Caregivers were interviewed regarding the effect of the approach. In most cases, participants appeared to enjoy the sessions, actively explored the 360° environment, and shared memories associated with the depicted locations, often spontaneously.info:eu-repo/semantics/publishedVersio

Direct evidence for As as a Zn-site impurity in ZnO

Arsenic has been reported in the literature as one of the few p-type dopants in the technologically promising II-VI semiconductor ZnO. However, there is an ongoing debate whether the p-type character is due to As simply replacing O atoms or to the formation of more complicated defect complexes, possibly involving As on Zn sites. We have determined the lattice location of implanted As in ZnO by means of conversion electron emission channeling from radioactive $^{73}$As. In contrast to what one might expect from its nature as a group V element, we find that As does not occupy substitutional O sites but in its large majority substitutional Zn sites. Arsenic in ZnO (and probably also in GaN) is thus an interesting example for an impurity in a semiconductor where the major impurity lattice site is determined by atomic size and electronegativity rather than its position in the periodic system

INCISÕES DE RELAXAMENTO PARA REPARAÇÃO DE DEFEITOS CIRÚRGICOS DE GRANDES DIMENSÕES NO COURO CABELUDO

91- year-old, Caucasian male patient, with a 35x40mm tumor, located in the right parietal region. Due to de dimension of the defects, primary closure was not able to accomplish, parallel relaxing incisions to the surgical defect was an option for reconstruction. Relaxing incisions to correct large defects of the scalp was proposed as an alternative and effective technique that avoids the execution of complex flaps and skin grafts procedures and has an acceptable cosmetic result.KEYWORDS – Reconstructive surgical procedures; Scalp; Surgical flaps.Doente do sexo masculino de 91 anos de idade, caucasiano, fototipo II, com nódulo ulcero-vegetante de 35x40mm, localizado na região parietal direita. Devido a dimensão do defeito não se conseguiu realizar encer- ramento primário, pelo que se optou por fazer incisões de relaxamento paralelas ao defeito cirúrgico. As incisões de relaxamento para correção de grandes defeitos do couro cabeludo e proposta como uma alternativa eficaz, que evita a realização de retalhos ou enxertos complexos, e que tem um resultado cosmético aceitável.PALAVRAS-CHAVE – Incisões de relaxamento; Cirurgia reconstrutiva; Couro cabeludo

Effectiveness of cleaning or disinfecting the urinary meatus before urinary catheterization: a systematic review

As infeções do trato urinário associadas à cateterização são muito frequentes no contexto comunitário e hospitalar. Existem atualmente várias recomendações para sua prevenção, contudo, quando abordado o soluto a utilizar no meato urinário previamente à algaliação continuam a persistir dúvidas. Assim, este estudo procurou determinar a eficácia da limpeza do meato urinário com água ou soro fisiológico comparativamente à sua assepsia por meio de uma revisão sistemática com metanálise. Para isso foram seguidos os princípios propostos pelo Cochrane Handbook , a análise crítica realizada por dois investigadores e a análise estatística com recurso ao programa STATA 11.1. Podemos concluir que a limpeza ou desinfeção do meato urinário previamente à cateterização vesical não é estatisticamente significativa (OR=1,07, IC 95%=0,68-1,68, p=0,779), existindo alguma evidência de que a utilização de água/soro fisiológico reduz as taxas de ITU.Las infecciones del tracto urinario asociadas con cateterismo son muy comunes en el contexto comunitario y hospitalario. Actualmente existen varias recomendaciones para su prevención. Sin embargo, las dudas persisten en la elección del soluto utilizado en el meato urinario antes del cateterismo. Por lo tanto, este estudio trata de determinar la eficacia de la limpieza del meato urinario con agua/solución salina comparativamente con su asepsia, mediante la realización de una revisión sistemática con meta-análisis. Para lo cual, se siguieron los principios propuestos por el Manual Cochrane, el análisis crítico realizado por dos investigadores y el análisis estadístico utilizando el programa STATA 11.1. Podemos concluir que la limpieza o desinfección del meato urinario antes del cateterismo no es estadísticamente significativo (OR=1,07, 95%CI=0,68-1,68, p=0,779) existiendo algunas evidencias de que el uso de agua/solución salina reduce las tasas de ITU.The urinary tract infections associated with catheterization are very common in hospital and home care contexts. Currently there are several recommendations for its prevention, however, when approaching the kind of solute used in the urinary meatus prior to catheterization doubts continue to persist. Thus this study aimed at determining the effectiveness of cleaning the urinary meatus with water or saline comparing to its sterilization through a systematic review and meta-analysis. In order to do so, the principles proposed by the Cochrane Handbook were followed, a critical analysis was conducted by two researchers and the statistical analysis was performed with the use of STATA 11.1. We concluded that the cleaning or disinfection of the urinary canal prior to bladder catheterization is not statistically significant (OR=1.07, CI 95%=0.68-1.68, p=0.779) and that there is some evidence that the use of water/saline reduces rates of UTI (urinary tract infection)

Redes sociais de apoio à paternidade na adolescência: um estudo multicêntrico

It describes a multicentric study conducted in three cities of different Brazilian states that seek to know the networks support to paternity in adolescence. It consists of two sub-studies: a quantitative and a qualitative, that respectivelysought to identify the profile of adolescent mothers and to investigate the support networks for adolescent fathers. The quantitative sample consists of 559 adolescent mothers and the population of the qualitative study was on 74 teenage parents. Data collection was supported in the quantitative study by structured interviews with all mothers that were giving birth in hospitals participating in the period from 2008 to 2009, and in the qualitative one were performed semistructured interviews, development of the genogram and eco-map to teenage parents. The data are still under review process. However, the results presented to date in the form of articles, dissertations, final works for graduations, oral communications and posters highlights the need for public policies directed at adolescents to help that they can do a more conscious and autonomous choice in relation to motherhood and fatherhood.Descriptors: paternity; adolescent; family; social support; health care

Influenza severe cases in hospitals, between 2014 and 2016 in Portugal

Rede Portuguesa de Laboratórios para o Diagnóstico da GripeBackground: Since 2009, the Portuguese Laboratory Network (PLNID) for Influenza Diagnosis has integrated 15 Laboratories in mainland and Atlantic Islands of Azores and Madeira. This PLNID added an important contribute to the National Influenza Surveillance Program regarding severe and hospitalized influenza cases. The present study aims to describe influenza viruses detected in influenza like illness (ILI) cases: outpatients (Outp), hospitalized (Hosp), and intensive care units (ICU), between 2014 and 2016. Methods: The PLNID performs influenza virus diagnosis by biomolecular methodologies. Weekly reports to the National Influenza Reference Laboratory ILI cases tested for influenza. Reports include data on detecting viruses, hospital assistance, antiviral therapeutics, and information on death outcome. Were reported during two winter seasons 8059 ILI cases,being 3560 cases in 2014/15 (1024 in Outp, 1750 Hosp, and 606 in ICU) and 4499 cases in 2015/2016 (1933 in Outp, 1826 Hosp, and 740 in ICU). Results: The higher percentage of influenza positive cases were detected in Outp in both seasons, 18% during 2014/15 and 20% in 2015/16. In 2014/15,influenza cases were more frequent in individuals older than 65 years old and these required more hospitalizations,even in ICU. In 2015/16,the influenza cases were mainly detected in individuals between 15-64 years old. A higher proportion of influenza positive cases with hospitalization in ICU were observed in adults between 45-64 years old.During the study period,the predominant circulating influenza viruses were different in the two seasons: influenza B and A(H3) co-circulated in 2014/15,and influenza A(H1)pdm09 was predominant during 2015/16. Even when influenza A is notthe dominant virus, A(H3) and A(H1)pdm09 subtypes correlate with higher detection rate in hospitalized cases (Hosp and UCI), with higher frequencies in adults older than 45. Influenza B,detected in higher proportion in outpatients, was frequently relatedwith influenza cases in younger age groups: 0-4 and 5-14 years old. Conclusions: This study highlights the correlation of theinfluenza virus type/subtype that circulates in each season with the possible need for hospitalization and intensive care in special groups of the population. Circulation of influenza A subtypes can cause more frequentdisease in individuals older than 45, with need of hospitalization including intensive care. On the other hand, influenza B is more frequently associated with less severe cases and with infection in children and younger adults. Influenza B circulation might predict lower number of hospitalizations.The identification of influenza type in circulation,byPLNID ineach season, could guide action planning measures in population health care.info:eu-repo/semantics/publishedVersio
