Health-related quality of life in school children: validation of instrument, child self assessment, parent-proxy assessment and school nursing documentation of health check-ups

The aims of this study were to validate an international Health-Related Quality of Life (HRQL) instrument, to describe child self and parent-proxy assessed HRQL at child age 10 to 12 and to compare child self assessments with parent-proxy assessments and school nursing documentation. The study is part of the Schools on the Move –research project. In phase one, a cross-cultural translation and validation process was performed to develop a Finnish version of Pediatric Quality of Life Inventory™ 4.0 (PedsQL™ 4.0). The process included a two-way translation, cognitive interviews (children n=7, parents n=5) and a survey (children n=1097, parents n=999). In phase two, baseline and follow-up surveys (children n=986, parents n=710) were conducted to describe and compare the child self and parent-proxy assessed HRQL in school children between the ages 10 and 12. Phase three included two separate data, school nurse documented patient records (children n=270) and a survey (children n=986). The relation between child self assessed HRQL and school nursing documentation was evaluated. Validity and reliability of the Finnish version of PedsQL™ 4.0 was good (Child Self Report α=0.91, Parent-Proxy Report α=0.88). Children reported lower HRQL scores at the emotional (mean 76/80) than the physical (mean 85/89) health domains and significantly lower scores at the age of 10 than 12 (dMean=4, p=<0.001). Agreement between child self and parent-proxy assessment was fragile (r=0,4, p=<0.001) but increased as the child grew from age 10 to 12 years. At health check-ups, school nurses documented frequently children’s physical health, such as growth (97%) and posture (98/99%) but seldom emotional issues, such as mood (2/7%). The PedsQLTM 4.0 is a valid instrument to assess HRQL in Finnish school children although future research is recommended. Children’s emotional wellbeing needs future attention. HRQL scores increase during ages between childhood and adolescence. Concordance between child self and parent-proxy assessed HRQL is low. School nursing documentation, related to child health check-ups, is not in line with child self assessed HRQL and emotional issues need more attention.

Impact of different light sources on broiler rearing environment

Broiler production is highly dependent on the use of artificial light. The light source may affect the effectiveness of housing conditions due to increasing ambient temperature and concentration of noxious gases. This research aimed to evaluate the effects of different bulb types on the thermal, aerial, and acoustic environment of broiler aviaries. The experiment was carried out at a commercial broiler farm in Dourados, Mato Grosso do Sul State, Brazil. Three aviaries were used, and two flocks of male broilers from Cobb® genetic strain were reared from the first day to slaughter. Each aviary was equipped with a different light source, comprising the adopted treatments (A1 - incandescent light bulb, control; A2 - sodium vapor light bulb; A3 - fluorescent light bulb). The aviaries were divided into nine quadrants, and the environmental data (ambient dry bulb temperature and relative humidity), litter surface temperature, CO2 and NH3 concentrations, and bird sound pressure behavior were recorded in each quadrant. The aviary with incandescent light presented higher air and litter temperatures, and concentration of gases than the other tested alternatives. It also presented higher level of sound pressure in the second week of the growing period; however, from this period up to slaughter, there was no effect of the light source on the results of broiler sound pressure level.

Effect of a simulated heat wave in thermal and aerial environment broiler-rearing environment

ABSTRACT Global warming increases the occurrence of events such as extreme heat waves. Research on thermal and air conditions affecting broiler-rearing environment are important to evaluate the animal welfare under extreme heat aiming mitigation measures. This study aimed at evaluating the effect of a simulated heat wave, in a climatic chamber, on the thermal and air environment of 42-day-old broilers. One hundred and sixty broilers were housed and reared for 42 days in a climatic chamber; the animals were divided into eight pens. Heat wave simulation was performed on the 42nd day, the period of great impact and data sampling. The analyzed variables were room and litter temperatures, relative humidity, concentrations of oxygen, carbon monoxide and ammonia at each pen. These variables were assessed each two hours, starting at 8 am, simulating a day heating up to 4 pm, when it is reached the maximum temperature. By the results, we concluded that increasing room temperatures promoted a proportional raise in litter temperatures, contributing to ammonia volatilization. In addition, oxygen concentrations decreased with increasing temperatures; and the carbon monoxide was only observed at temperatures above 27.0 °C, relative humidity higher than 88.4% and litter temperatures superior to 30.3 °C.

Testing pigs of non-technified rearing farms for serum antibodies against Taenia solium in a region of the state of São Paulo, Brazil

Abstract: Taenia solium is a zoonotic tapeworm of great importance in developing countries, due to the occurrence of human taeniasis and cysticercosis. Pigs have an important role in the biological cycle of the parasite as intermediate hosts. The scientific literature has been describing risk factors associated with the occurrence of this disease that must be avoided in countries with poor sanitation, in order to reduce the exposure of swine to the parasite eggs. This research focused on testing pigs of non-technified rearing farms for serum antibodies against Taenia solium in the region of Jaboticabal municipality, in the state of São Paulo, Brazil. The found prevalence was 6.82% (CI 95% 4.18 - 9.45) at animal level and 28.87% (CI 95% 16.74 - 40.40) at herd level. These figures are probably associated with low technification adoption during animal rearing in the studied area, which increased the exposure of the animals to risk factors associated with the occurrence of Taenia solium complex. The results found based on serological evidences of swine cysticercosis in the studied region serves as a warning to public sanitary authorities to improve public health and control T. solium.

Routine post-weaning handling of rats prevents isolation rearing-induced deficit in prepulse inhibition

Rats reared under isolation conditions from weaning present a number of behavioral changes compared to animals reared under social conditions (group housing). These changes include deficits in prepulse inhibition (PPI) of the startle reflex to a loud sound. PPI refers to the reduction of the magnitude of the startle reflex when a relatively weak stimulus (the prepulse) precedes by an appropriate time interval the intense startle-elicing stimulus (the pulse). PPI is useful for studying sensorimotor integration. The present study evaluated the effect of handling on the impairment of PPI induced by isolation-rearing. Male Wistar rats (N = 11-15/group) were housed in groups (5 per cage and handled three times a week) or isolated (housed individually) since weaning (21 days) for 10 weeks when they reach approximately 150 g. The isolated rats were divided into "minimally handled" animals (handled once a week for cleaning purposes only) or "handled" animals (handled three times a week). This handling consisted of grasping the rat by the tail and moving it to a clean cage (approximately 5 s). A statistically significant reduction (52%) in the PPI test was found only in the isolated group with minimal handling while no difference was seen between grouped animals and isolated handled animals. These results indicate that isolation rearing causes disruption in the PPI at adult age, which serves as an index of attention deficit. This change in the sensory processing of information induced by post-weaning isolation can be prevented by handling during the development of the animal.

Prevalence of child malnutrition at a university hospital using the World Health Organization criteria and bioelectrical impedance data

Malnutrition constitutes a major public health concern worldwide and serves as an indicator of hospitalized patients’ prognosis. Although various methods with which to conduct nutritional assessments exist, large hospitals seldom employ them to diagnose malnutrition. The aim of this study was to understand the prevalence of child malnutrition at the University Hospital of the Ribeirão Preto Medical School, University of São, Brazil. A cross-sectional descriptive study was conducted to compare the nutritional status of 292 hospitalized children with that of a healthy control group (n=234). Information regarding patients’ weight, height, and bioelectrical impedance (i.e., bioelectrical impedance vector analysis) was obtained, and the phase angle was calculated. Using the World Health Organization (WHO) criteria, 35.27% of the patients presented with malnutrition; specifically, 16.10% had undernutrition and 19.17% were overweight. Classification according to the bioelectrical impedance results of nutritional status was more sensitive than the WHO criteria: of the 55.45% of patients with malnutrition, 51.25% exhibited undernutrition and 4.20% were overweight. After applying the WHO criteria in the unpaired control group (n=234), we observed that 100.00% of the subjects were eutrophic; however, 23.34% of the controls were malnourished according to impedance analysis. The phase angle was significantly lower in the hospitalized group than in the control group (P<0.05). Therefore, this study suggests that a protocol to obtain patients’ weight and height must be followed, and bioimpedance data must be examined upon hospital admission of all children.

Lipoprotein glomerulopathy: a case report of a rare disease in a brazilian child

Lipoprotein glomerulopathy (LPG) is a rare autosomal recessive glomerulopathy associated with the deposition of lipoprotein thrombi in the capillary lumina due to apoE gene mutations. Abnormal plasma lipoprotein profile and marked increase in serum apoliprotein E (apoE) are characteristic clinical data. The compromised patients can present nephrotic syndrome, hematuria, and progressive renal failure. Herein, the authors present the first described case of LPG in a Brazilian male patient, 11 years, who presented with a steroid-resistant nephrotic syndrome. Renal function was normal. Kidney biopsy showed markedly enlarged glomerulus, with dilated capillary loops and weak eosinophilic lipoprotein thrombi in the capillary lumina. Interstitium, tubules, arteries, and veins showed normal histologic aspect. Genotypic study for the apoE gene showed the presence of the alleles E3 and E4. The diagnosis of LPG was then performed. The patient received lipid-lowering treatment. After 2 years of follow-up, renal function is gradually decreasing, with persisting heavy proteinuria, despite a marked decrease in serum cholesterol and triglycerides levels.

Psychological well-being of the parents and child development, behavior, and quality of life in very low birth weight infants

The parents of premature infants, especially the mothers, are at increased risk for distress. Infants born prematurely are at risk for developmental problems. The aim of this study was to investigate whether the psychological well-being of both parents is associated with child development in very low birth weight (VLBW, ≤1500g) children. The burden of prematurity-related morbidity to the children and to the family was also assessed. A cohort of 201 VLBW infants born during 2001–2006 in the Turku University Hospital, Finland, and their parents were studied (I–IV). One study included a control group (n=166) of full-term infants (IV). The psychological well-being of the parents was evaluated by assessments of depressive symptoms, parenting stress, the sense of coherence and general family functioning. Cognitive, behavioral, and socio-emotional development, and the health-related quality of life (HRQoL) of the children were determined when the children were 2 to 8 years old. The psychological well-being of the parents was associated with the cognitive, behavioral and social development of the VLBW children. The VLBW infants with prematurity-related morbidities had a poorer HRQoL and the general functioning of the family was inferior compared to the control children and their families. 64.5% of the VLBW children survived without morbidities. Most of the VLBW children did not have significant behavior problems (93%), had normal social skills (63%), had no emotional problems (64%), and had no problems in executive functioning (62%). Only 3% of the surviving VLBW infants had significant cognitive delay. In conclusion, the depressive symptoms and stress of the parents can be risk factors for disadvantageous child development, while a strong sense of coherence can be protective. Parents of the premature children with developmental delays might also experience more depressive symptoms and stress than other parents. Prematurity-related morbidities were a burden to the VLBW child as well as to the family.

Ruumis, affekti ja tulemisen prosessi : feministinen, affektiivinen ja uusmaterialistinen näkökulma Heidi Tikan videoinstallaatioon Mother, Child (2011/2000)

Tutkielmassa tarkastellaan suomalaisen kuvataiteilija Heidi Tikan videoinstallaatiota Mother, Child (2011/2000). Tutkielmassa tutkitaan installaation uusinta, vuonna 2011 tehtyä versiota. Mother, Child on liikkuvan kuvan installaatio, jossa videokuva projisoidaan valkoiselle harsokankaalle, jota istuimelle asettunut katsoja pitää käsivarsillaan. Kankaalle heijastuu liikkuvaa kuvaa poikavauvasta, joka imee naisen rintaa. Installaatioon osallistuessaan katsojalle syntyy vaikutelma siitä, että hän pitää vauvaa sylissään, jolloin hän voi eläytyä lasta hoivaavan ja imettävän äidin asemaan. Lisäksi tutkielmassa huomioidaan, kuinka installaation tekniikan ansiosta videolla näkyvä vauva ja installaation katsoja voivat olla vuorovaikutuksessa keskenään. Tutkielma jakautuu kolmeen käsittelylukuun, joissa jokaisessa lähestytään Mother, Child -installaatiota eri näkökulmasta: ensimmäisessä käsittelyluvussa Mother, Child -installaatiota tarkastellaan feministisen taiteentutkimuksen lähtökohdista, toisessa käsittelyluvussa installaation analyysissä sovelletaan affektiteorioita ja kolmannen käsittelyluvun teoreettisen viitekehyksen muodostaa uusmaterialismi. Tutkimuskysymykset keskittyvät installaation katsojan ja videolla näkyvän naisen ruumiin tarkasteluun, installaation affekteihin sekä installaation materiaalisuuteen ja tulemisen prosessiin. Valittujen näkökulmien avulla sekä molekulaarisen taidehistorian metodia ja deleuze-guattarilaista filosofiaa soveltamalla tutkielmassa löydetään vaihtoehtoisia tapoja, joilla lähestyä Mother, Child -installaatiota jonakin muuna kuin representaationa: muotoutuvana, materiaalisena ja affektiivisena katsojan ja installaation ainutkertaisena kohtaamistapahtumana. Maailman representoimisen eli esittämisen tai samankaltaisten äitiyskuvien toisintoiston sijaan tutkielmassa korostuu ajatus Mother, Child -installaation olemassaolosta omana aktiivisesta materiasta muodostuvana itsenään ja osana todellista, materiaalista maailmaa. Tutkielmassa installaation olemassaolo ja jatkuva muotoutuminen määritellään tulemisen prosessiksi. Mother, Child edellyttää katsojansa ruumiillista ja affektiivista osallistumista tapahtuakseen eli tullakseen olevaksi. Tutkielmassa esitetään, että osallistavaa taidetta tutkittaisiin osallistuvan taiteentutkimuksen ja affektiivisen virittäytymisen keinoin, jolloin tutkija voi hyödyntää tunnereaktioitaan ja affektoitumisen kokemuksiaan tutkimuksessa. Tällöin tutkimuskohteeseen suhtaudutaan tutkimuksen objektin sijaan keskustelukumppanina ja tutkija asettuu samalle tasolle taiteen kanssa. Tutkijan on antauduttava taiteen molekulaarisen virran vietäväksi, mikä merkitsee herkkyyttä ja avoimuutta taiteen materian ja affektien liikkeelle sekä taiteen lähelle menemistä eli seuraamista.

The quality of the mother-child relationship during collaborative problem solving /

The quality of the mother-child relationship was examined in relation to joint planning, maternal teaching strategies, maternal emotional support, mutual positive affect and attachment security. Fifty-five grade five children and their mothers participated in a laboratory session comprised of various activities and completed questionnaires to evaluate attachment security. Joint planning and social problem solving were assessed observationally during an origami task. Problem solving effectiveness was unrelated to maternal teaching strategies, maternal encouragement and mutual positive affect. A marginally significant relationship was found between maternal encouragement and active child participation. Attachment security was found to be significantly related to sharing of responsibility during local planning, but only for child autonomous performance. An examination of conditional probabilities revealed that mutual positive affect did not increase the likelihood of subsequent mother-child dyadic regulation. However, mutual positive affect was found to be significantly related to both active child participation and dyadic regulation. The hypothesis predicting a mediational model was not supported. The implications of these findings in the theoretical and empirical literature were considered and suggestions for future research were made.

Academics as parents--parents as academics : a study of the integration of intellectual and child-care labours /

Discussions concerning the challenges of combining work and family are certainly not new, and still actively continue. There is, however, a silence in the related literature regarding a comprehensive description of integrating specifically university academic ~. work and family responsibilities. This silence is especially evident for men who are parents as well as academics. With the participation of 4 key informants, this qualitative research study gave voice to men and women who participate in the academic labour of a Canadian university as professors, and as graduate students, along with the parenting labour of at least 1 child under the age of7. Methodology was developed to reveal in-depth perspectives regarding the work practices employed by 4 key informants as they combined intellectual and child-care responsibilities. Multiple data collection methods included journal reflections, day time observation sessions, a focus group, and a final evaluation questionnaire. Using research findings, together with information extrapolated from Three Models of the Family (Eichler, 1997), this study also took steps toward developing a Proposed "Three Models of the University," to offer explanation for the work practices of the key informants as academics/parents, and also for future consideration in university policy formation.

Childlessness in a child-centered environment : the experiences of voluntarily childless female teachers /

In the literature on voluntary childlessness there is a lack of research on the types of occupations held by women who choose not to mother and how their fertility choice influences their occupational experiences. At the same time, the experience ofwomen with regard to the childfree choice has not been adequately addressed in contemporary feminist literature. In the field of education, much has been written about the association between mothering and teaching. Thus, childfree teachers become particularly interesting since they made seemingly paradoxical choices in that they chose not to bear and rear children yet they chose an occupation in which they are surrounded by and responsible for the daily care of many children. To gain an understanding of the work-related experiences of childfree women, in-depth interviews were conducted with 7 voluntarily childless female elementary school teachers from Southern Ontario. In addition, a focus group interview in which 3 of the 7 childfree teachers participated was conducted. Findings revealed that these women's "choice" to be childless was the result of complex circumstances and multiple motivations. Also, despite their decision to forgo the traditional female role of mother, these women held surprisingly conventional beliefs with regard to family and gender roles. In addition, these childfree women at times identified themselves as mother-like when teaching, yet at other times distanced themselves as teachers from mothers. Finally, results showed that these women experienced both direct and indirect pronatalist pressures outside as well as inside the workplace as a result of their childfree status.

The only child grows up: exploring adult only-child educators /

The purpose of this study was to examine the experiences of adult only-child educators. The researcher explored the extent to which the experiences of growing up in a one-child family influenced the participants' professional experiences. This was a qualitative study. A narrative case study approach was used, and data were collected from 4 participants through 1 -to- 1 interviews. The narratives were analyzed, and common themes were identified. The findings showed that many of the participants' only-child experiences have influenced their professional roles as educators. This was largely with respect to their interactions with students. These participants valued positive relationships founded on genuine care and concern for their students. The participants also fostered a positive educational environment that provided high levels of support for the social learning and character development of their students. There are several implications for educational practice resulting from this study. Educators and other school personnel must be critically aware of meeting the socialization needs of their students. Consideration must be given to developing schoolwide initiatives related to the social skills development and character education of students. In addition, preservice and inservice teacher education programs must ensure that educators are prepared to provide rich environments where relationships with students are central and social learning opportunities are prevalent.

A sequential analysis of therapist scaffolding and child concept formation in narrative therapy

Narrative therapy is a postmodern therapy that takes the position that people create self-narratives to make sense of their experiences. To date, narrative therapy has compiled virtually no quantitative and very little qualitative research, leaving gaps in almost all areas of process and outcome. White (2006a), one of the therapy's founders, has recently utilized Vygotsky's (1934/1987) theories of the zone of proximal development (ZPD) and concept formation to describe the process of change in narrative therapy with children. In collaboration with the child client, the narrative therapist formalizes therapeutic concepts and submits them to increasing levels of generalization to create a ZPD. This study sought to determine whether the child's development proceeds through the stages of concept formation over the course of a session, and whether therapists' utterances scaffold this movement. A sequential analysis was used due to its unique ability to measure dynamic processes in social interactions. Stages of concept formation and scaffolding were coded over time. A hierarchical log-linear analysis was performed on the sequential data to develop a model of therapist scaffolding and child concept development. This was intended to determine what patterns occur and whether the stated intent of narrative therapy matches its actual process. In accordance with narrative therapy theory, the log-linear analysis produced a final model with interactions between therapist and child utterances, and between both therapist and child utterances and time. Specifically, the child and youth participants in therapy tended to respond to therapist scaffolding at the corresponding level of concept formation. Both children and youth and therapists also tended to move away from earlier and toward later stages of White's scaffolding conversations map as the therapy session advanced. These findings provide support for White's contention that narrative therapists promote child development by scaffolding child concept formation in therapy.
