Playing to Create New Ways of Playing: A Child with Prader-Willi Syndrome

This investigation evaluates the possibility of constructing new ways of playing for a child with Prader-Willi syndrome, by means of occupational therapy. It is a qualitative study which makes use of the case study methodology, whose starting point is the clinical intervention as data collect field. It also presents a short revision of the literature to subside discussions and reflections. It was observed that through the playing experience the occupational therapist led the child to know his own limitations and possibilities, by making him discover new ways of doing activities. Observing the therapist and learning with her, the patient experienced different situations throughout the therapeutic relationship, what enabled him to experiment them in his everyday life. Finally, this study aims at showing the clinical reasoning of an occupational therapist with a view to demonstrate Brazilian therapeutical conduct.

Lipid levels in the second year of life among HIV-infected and HIV-exposed uninfected Latin American children

Background: Dyslipidemia is observed among older children and adults with HIV. We examined nonfasting cholesterol and triglycerides in two groups of 12-23-month-old Latin American children - HIV-infected vs. HIV-exposed but uninfected (HEU). Methods: HIV-infected and HEU children in Latin America and Jamaica were enrolled in an observational cohort. Eligibility for this analysis required having cholesterol and triglyceride results available during the second year of life. Results: HIV-infected (n = 83) children were slightly older at the time of lipid testing than the HEU (n 681). Forty percent of the HIV-infected children were on protease inhibitor-based antiretroviral therapy (ART); 41% were not on ART. There was no statistically significant difference in mean cholesterol concentrations (mg/dl) by HIV status; however, the HIV-infected children had higher mean triglyceride concentrations. The prevalence of high cholesterol (>200 mg/dl) and high triglycerides (>110 mg/dl) was higher among the HIV-infected vs. HEU. Among the HIV-infected children, mean cholesterol and triglyceride concentrations varied by ART. Children receiving no ART had a significantly lower mean cholesterol concentration. Those receiving protease inhibitor-containing ART had a significantly higher mean triglyceride concentration compared to the other two antiretroviral regimen groups. Conclusion: A greater proportion of HIV-infected children at 12-23 months have hyperlipidemia when compared to HEU children, with the highest triglyceride concentrations observed among those receiving protease inhibitor-containing ART, and the lowest cholesterol levels among those not receiving ART. Implications of these findings will require continued follow-up of HIV-infected children who initiate therapy early in life. (C) 2012 Wolters Kluwer Health vertical bar Lippincott Williams & Wilkins

Assessment of referrals to an OT consultation-liaison service: a retrospective and comparative study

The objective was to conduct a retrospective and comparative study of the requests for consultation-liaison (RCLs), during a period of six years, sent to the Occupational Therapy (OT) team that acts as the Consultation-liaison Service in Mental Health. During the studied period 709 RCLs were made and 633 patients received OT consultations. The comparison group was extended to 1 129 consecutive referrals to the psychiatric CL service, within the same period and that were also retrospectively reviewed. Regarding to RCLs to the OT team, most of the subjects were women with incomplete elementary schooling, with a mean age of 39.2 years, and were self-employed or retired. Internal Medicine was responsible for most of the RCLs. The mean length of hospitalization was 51 days and the mean rate of referral was 0.5%, with the most frequent reason for the request being related to the emotional aspects and the most frequent psychiatric diagnosis was mood disorder. It is concluded that there is a clear demand for the development of consultation-liaison in OT, particularly with regard to the promotion of mental health in general hospitals.

Understanding the correlates of adolescents' dietary intake patterns. A multivariate analysis

We investigated dietary intake patterns (DIP) in adolescents (14-18 year-olds) and the association with demographic and socioeconomic characteristics and lifestyle variables. This school-based survey was carried out among high school students from the city of Maringa in the state of Parana (PR), Brazil (2007). The sample included 991 students (54.5% girls) from high schools. DIPs were investigated by the frequency of weekly consumption of each food group: vegetables, fruit, rice, beans, fried food, sweet food, milk, soda, meat, eggs, alcoholic drinks. Independent variables were: demographic and socioeconomic characteristics and lifestyle variables. DIPS were identified using principal component analysis with orthogonal rotation (varimax). Three components were extracted. Component 1 (fried foods, sweets and soft drinks) was positively associated with not having breakfast for girls and dinner for boys. Moreover, component 2 (consumption of fruit and vegetables) was positively associated with having breakfast at home for boys and number of meals for girls. Component 3 (beans, eggs and meat) was positively associated with having lunch, employment and sedentary behavior level for girls. However, it was negatively associated with having lunch and dinner for boys. Adolescents who have healthier eating patterns also had other healthier behaviors regardless of gender. However, factors associated with dietary patterns differ between boys and girls. (C) 2012 Elsevier Ltd. All rights reserved.

Cytostatic in vitro Effects of DTCM-Glutarimide on Bladder Carcinoma Cells

Bladder cancer is a common malignancy worldwide. Despite the increased use of cisplatin-based combination therapy, the outcomes for patients with advanced disease remain poor. Recently, altered activation of the PI3K/Akt/mTOR pathway has been associated with reduced patient survival and advanced stage of bladder cancer, making its upstream or downstream components attractive targets for therapeutic intervention. In the present study, we showed that treatment with DTCM-glutaramide, a piperidine that targets PDK1, results in reduced proliferation, diminished cell migration and G1 arrest in 5637 and T24 bladder carcinoma cells. Conversely, no apoptosis, necrosis or autophagy were detected after treatment, suggesting that reduced cell numbers in vitro are a result of diminished proliferation rather than cell death. Furthermore previous exposure to 10 mu g/ml DTCM-glutarimide sensitized both cell lines to ionizing radiation. Although more studies are needed to corroborate our findings, our results indicate that PDK1 may be useful as a therapeutic target to prevent progression and abnormal tissue dissemination of urothelial carcinomas.

Directions for advancing the study of work transitions in the 21st century

Objectives: The purpose of this article is to share the details, outcomes and deliverables from an international workshop on work transitions in London, Ontario, Canada. Participants: Researchers, graduate students, and community group members met to identity ways to advance the knowledge base of strategies to enhance work participation for those in the most disadvantaged groups within society. Methods: A participatory approach was used in this workshop with presentations by researchers and graduate students. This approach included dialogue and discussion with community members. In addition, small group dialogue and debate, world cafe discussions, written summaries of group discussion and reflection boards were used to bring new ideas to the discussion and to build upon what we know. Findings: Two research imperatives and six research recommendations were identified to advance global dialogue on work transitions and to advance the knowledge base. Occupational justice can be used to support future research directions in the study of work transitions. Conclusions: Moving forward requires a commitment of community of researchers, clinicians and stakeholders to address work disparities and implement solutions to promote participation in work.

Deficiências após a alta medicamentosa da hanseníase: prevalência e distribuição espacial

OBJETIVO: Estimar a frequência das deficiências físicas em pacientes tratados de hanseníase após alta medicamentosa e analisar sua distribuição espacial. MÉTODOS: Estudo descritivo transversal com 232 pessoas tratadas de hanseníase de 1998 a 2006. As deficiências físicas foram avaliadas pelo Grau de Incapacidades da Organização Mundial da Saúde (GI/OMS) e pelo Eye-Hand-Foot (EHF). Os ex-pacientes foram geocodificados pelo endereço de residência e os serviços de reabilitação pelo endereço de sua sede. Foram apresentadas as frequências para o total e para os grupos grau 0, grau 1 e grau 2 do GI-OMS, considerando-se as variáveis clínicas e sociodemográficas na análise descritiva. Foram utilizados os testes t de Student, qui-quadrado (χ2) ou de Fisher, conforme apropriado, considerando-se significativos p < 0,05. RESULTADOS: Cerca de 51,6% era do sexo feminino, com média de idade de 54 anos (dp15,7); 30,5% tinha menos de dois anos de educação formal; 43,5% trabalhava e 26,9% estava aposentado; a forma dimorfa predominou (39,9%). As deficiências avaliadas pelo GI-OMS e pelo EHF atingiram 32% dos ex-pacientes. A presença de deficiências foi maior com o aumento da idade (p = 0,029), em casos multibacilares (p = 0,005) e com julgamento ruim do paciente sobre sua saúde física (p < 0,001). Os que necessitavam de prevenção/reabilitação percorreram distância média de 5,5 km até o serviço de reabilitação. As pessoas com deficiência física estavam distribuídas em todo o município, mas concentravam-se na área mais populosa e de maior carência socioeconômica. CONCLUSÕES: A frequência de deficiências é elevada após a alta medicamentosa. Os ex-pacientes mais velhos, os que tiveram formas multibacilares da doença, os de baixa escolaridade e os que julgam mal a própria saúde física merecem atenção especial para a prevenção e reabilitação de deficiências. A distância entre os serviços de reabilitação e as residências dos pacientes requer reorganização da rede de atendimento no município.

Waist circumference and waist circumference to height ratios of Kaingáng indigenous adolescents from the State of Rio Grande do Sul, Brazil

The aim of this study was to describe the distribution of waist circumference (WC) and WC to height (WCTH) values among Kaingáng indigenous adolescents in order to estimate the prevalence of high WCTH values and evaluate the correlation between WC and WCTH and body mass index (BMI)-for-age. A total of 1,803 indigenous adolescents were evaluated using a school-based cross-sectional study. WCTH values > 0.5 were considered high. Higher mean WC and WCTH values were observed for girls in all age categories. WCTH values > 0.5 were observed in 25.68% of the overall sample of adolescents. Mean WC and WCTH values were significantly higher for adolescents with BMI/age z-scores > 2 than for those with normal z-scores. The correlation coefficients of WC and WCTH for BMI/age were r = 0.68 and 0.76, respectively, for boys, and r = 0.79 and 0.80, respectively, for girls. This study highlights elevated mean WC and WCTH values and high prevalence of abdominal obesity among Kaingáng indigenous adolescents.

O cotidiano, o lúdico e as redes relacionais: a artesania do cuidar em terapia ocupacional no hospital

O objetivo deste trabalho é refletir sobre os modos de fazer, sentir e conduzir as ações de contar histórias em uma enfermaria pediátrica. Essas ações decorrem de atividades de extensão universitária, no âmbito da terapia ocupacional. A reflexão, realizada a partir da revisão de literatura e discussão sobre anotações de campo do projeto, pauta-se por norteadores teóricos baseados nas tecnologias do cuidado e no brincar dentro do contexto das intervenções no hospital, sob a perspectiva da integralidade e da humanização do cuidado. A contação de histórias é apresentada enquanto forma de promover escuta, acolhimento, afetações diversas e processos vinculares, possibilitando a constituição de uma rede de sustentabilidade relacional, envolvendo os atores que circulam na enfermaria. Reafirma, assim, as práticas profissionais em saúde no hospital a partir de uma construção permanente junto ao sujeito por meio de ferramentas tecnológicas singularizadoras que promovam encontros-acontecimentos.

Ocupação, bem-estar e satisfação de vida: a experiência de um modelo alternativo de estágio em terapia ocupacional na Austrália

Apresenta-se um modelo alternativo de estágio em terapia ocupacional desenvolvido na Deakin University - Austrália, denominado Ocupação, bem-estar e satisfação de vida - Occupation, wellness and life-satisfaction (OWLS). O OWLS oferece, aos estudantes, a oportunidade de atuação em contextos não tradicionais, permitindo um aprendizado estratégico em ambientes não clínicos, incluindo o trabalho com outros profissionais não-terapeutas ocupacionais e com diferentes culturas de trabalho e práticas, em resposta a lacunas identificadas na comunidade. Favorece oportunidades para desenvolver habilidades, tais como: a promoção da saúde, avaliação e educação em saúde e intervenção em escolas, melhorando, assim, a saúde e o bem-estar da comunidade. O programa tem contribuído para o desenvolvimento de novos projetos, com resultados positivos alcançados pelos estudantes, representando uma importante estratégia de ensino para capacitação do profissional de terapia ocupacional, ampliando, assim, a área de atuação.

Untersuchungen zur Chemosensitivität von testikulären Tumorzellen gegenüber Cisplatin

Metastasierender Krebs ist bei Erwachsenen in der Regel nicht heilbar. Eine Ausnahme stellen testikuläre Keimzelltumoren (TKZT) dar, da über 75 % der Patienten mit fortgeschrittenen metastasierenden TKZT mit einer auf Cisplatin basierenden Kombinations-Chemotherapie geheilt werden können. Zelllinien, die aus TKZT isoliert wurden, behalten diese Cisplatin-Sensitivität in vitro bei. Somit spiegeln Testistumorzelllinien die klinische Situation wider und sind deswegen ein gutes Modellsystem um zu untersuchen, welche Faktoren der Cisplatin-Sensitivität zugrunde liegen. Die Ursachen der Cisplatin-Sensitivität in Testistumoren sind nicht bekannt. Es wurde bereits gezeigt, dass Testistumorzellen eine geringe Kapazität für die Entfernung von Cisplatin-induzierten DNA-Platinierungen aufweisen. Dieser Defekt in der DNA-Reparatur könnte ein Faktor für die beobachtete Cisplatin-Sensitivität sein. Cisplatin induziert sowohl Intrastrang-Vernetzungen als auch Interstrang-Vernetzungen (ICLs). Die Bildung und Reparatur der Cisplatin-induzierten Intrastrang-Vernetzungen wurde mittels DNA-Slot-Blot, die Bildung und Entfernung von Interstrang-Vernetzungen wurde mithilfe des Comet-Assays untersucht. In der vorliegenden Arbeit wurde gezeigt, dass die Reparatur von Intrastrang-Vernetzungen in Testis- und Blasentumorzelllinien vergleichbar ist. Somit sind Testistumorzellen in diesem Reparaturweg nicht beeinträchtigt. Im Unterschied dazu zeigte sich, dass Testistumorzellen die ICLs nicht oder nur mit einer reduzierten Kapazität entfernen können.Da die ICL-Reparatur über die Bildung von DNA-Doppelstrangbrüchen (DSB) mit anschließender DSB-Reparatur verläuft, wurde die Kinetik der DSB-Reparatur anhand der Immundetektion der Histon-Variante γH2AX, die zur Visualisierung von DSB verwendet wird, verfolgt. γH2AX Foci wurden nach Behandlung mit Cisplatin in Testistumorzellen und Blasentumorzellen gebildet. Anders als in Blasentumorzellen blieb der Prozentsatz an γH2AX-positiven Zellen in Testistumorzellen bestehen. Offensichtlich konnten die Testistumorzellen die Cisplatin-induzierten ICLs nicht korrekt prozessieren, was dazu führte, dass γH2AX Foci persistierten. Da unreparierte DNA-Läsionen eine DNA-schadensabhängige Antwort einleiten können, wurde die Aktivierung der Hauptfaktoren dieser Signalwege untersucht. In den Testistumorzellen zeigte sich eine Erhöhung der p53 Proteinmenge nach Cisplatin-Behandlung. Des Weiteren wurde die durch Cisplatin induzierte Aktivierung von ATM/ATR, Chk1/Chk2, Bax und Noxa in Testis- und Blasentumorzellen vergleichend untersucht. Es wurde bereits gezeigt, dass der Reparaturfaktor ERCC1-XPF in Testistumorzelllinien reduziert vorliegt. Um eine mögliche Rolle von ERCC1-XPF für die Reparatur-Defizienz der ICLs und Cisplatin-Sensitivität in Testistumorzellen zu analysieren, wurde ERCC1-XPF in der Testistumorenzelllinie 833K mithilfe eines Expressionsvektors überexprimiert, und der Einfluss von ERCC1-XPF auf ICL-Reparatur sowie Cisplatin-Sensitivität wurde ermittelt. Überexpression von ERCC1-XPF führte zur Reparatur der ICLs in 833K-Zellen und verminderte die Cisplatinsensitivität. Somit scheint die Cisplatinsensitivität der Testistumorzellen, zumindest zum Teil, auf einer verminderten ICL-Reparatur zu beruhen. Des Weiteren wurde in „proof of principle“ Experimenten ERCC1-XPF in der Cisplatin-resistenten Blasentumorzelllinie MGH-U1 mittels siRNA herunterreguliert, und die Auswirkung der Herunterregulation auf die ICL-Reparatur und die Cisplatinsensitivität wurde geprüft. RNA-Interferenz-vermittelte Herunterregulierung von ERCC1-XPF reduzierte die Prozessierung der Cisplatin-induzierten ICLs und verstärkte die Cisplatinsensitivität in MGH-U1 Zellen. Somit wurde in dieser Arbeit zum ersten Mal gezeigt, dass die Testistumorzellen in Vergleich zu Blasentumorzellen in der Reparatur von ICLs defizient sind, wobei die verminderte ICL-Reparatur auf die geringe Expression von ERCC1-XPF zurückgeführt werden konnte. Diese ICL-Reparatur-Defizienz könnte, zumindest zu einem Teil, für die Sensitivität der Testistumoren gegenüber Cisplatin verantwortlich sein.

Safety and therapeutic efficacy of adoptive p53-specific T cell antigen receptor (TCR) gene transfer

Immunotherapy with T cells genetically modified by retroviral transfer of tumor-associated antigen (TAA)-specific T cell receptors (TCR) is a promising approach in targeting cancer. Therefore, using a universal TAA to target different tumor entities by only one therapeutic approach was the main criteria for our TAA-specific TCR. Here, an optimized (opt) αβ-chain p53(264-272)-specific and an opt single chain (sc) p53(264-272)-specific TCR were designed, to reduce mispairing reactions of endogenous and introduced TCR α and TCR β-chains, which might lead to off-target autoimmune reactions, similar to Graft-versus-host disease (GvHD). rnIn this study we evaluated the safety issues, which rise by the risk of p53TCR gene transfer-associated on/off-target toxicities as well as the anti-tumor response in vivo in a syngeneic HLA-A*0201 transgenic mouse model. We could successfully demonstrate that opt sc p53-specific TCR-redirected T cells prevent TCR mispairing-mediated lethal off-target autoimmunity in contrast to the parental opt αβ-chain p53-specific TCR. Since the sc p53-specific TCR proofed to be safe, all further studies were performed using sc p53-specific TCR redirected T cells only. Infusion of p53-specific TCR-redirected T cells in Human p53 knock-in (Hupki) mice after lymphodepletion-preconditioning regimen with either sublethal body irradiation (5Gy) or chemotherapy (fludarabine and cyclophosphamide) in combination with vaccination (anti-CD40, CpG1668 and p53(257-282) peptide) did not result in a depletion of hematopoietic cells. Moreover, adoptive transfer of high numbers of p53-specific TCR-redirected T cells in combination with Interleukin 2 (IL-2) also did not lead to toxic on-target reactions. The absence of host tissue damage was confirmed by histology and flow cytometry analysis. Furthermore, p53-specific TCR-redirected T cells were able to lyse p53+A2.1+ tumor cells in vitro. However, in vivo studies revealed the potent suppressive effect of the tumor microenvironment (TME) mediated by tumor-infiltrating myeloid-derived suppressor cells (MDSC). Accordingly, we could improve an insufficient anti-tumor response in vivo after injection of the sc p53-specific TCR-redirected T cells by additional depletion of immunosuppressive cells of the myeloid lineage.rnTogether, these data suggest that the optimized sc p53(264-272)-specific TCR may represent a safe and efficient approach for TCR-based gene therapy. However, combinations of immunotherapeutic strategies are needed to enhance the efficacy of adoptive cell therapy (ACT)-mediated anti-tumor responses.

I think of my family, therefore I am: perceptions of daily occupations of some Albanians in Switzerland

The purpose of this qualitative study was to increase the understanding of the relationship between culture and occupation by exploring the perceptions of current daily occupations of some immigrants living in Switzerland. Semi-structured interviews with eight healthy Muslim Albanian men doing blue-collar work were analysed in a comparative manner followed by an interpretation. Three themes were identified: "Everything I do I do for my family"; "Where do I belong?"; and "Doing something for myself". These themes reflect the occupational perceptions of the participants. The findings are discussed in relation to the ongoing discourses on individualism and collectivism. To offer occupational therapy appropriately to a multicultural clientele the findings indicate the necessity to be conscious of the differences between one's own and the client's attitudes regarding individualism and collectivism.
