Fibrose cística é uma doença hereditária, caracterizada por alterações no transporte de cloro nas membranas das células epiteliais, gerando a produção de muco espesso e anormal, o que pode obstruir os ductos de glândulas exócrinas de vários órgãos. As manifestações clínicas principais da doença abrangem os sistemas respiratório (com infecções pulmonares recorrentes e crônicas) e gastrointestinal (com insuficiência pancreática e consequente má-digestão e absorção de nutrientes, levando a desnutrição energético-protéica). Existem evidências de que a constituição da microbiota intestinal pode influenciar a colonização do trato respiratório de indivíduos com fibrose cística. Esta dissertação teve como objetivo realizar revisão sistemática e metanálise das publicações científicas sobre o uso de pré, pró ou simbióticos em fibrose cística, além de avaliar a situação nutricional dos pacientes com fibrose cística acompanhados no Instituto da Criança - HCFMUSP. A revisão sistemática e metanálise seguiu protocolo proposto pela Colaboração Cochrane, com buscas em bases de dados eletrônicas com os termos prebioticos ou probióticos ou simbióticos e fibrose cística. Foram incluídos ensaios clínicos randomizados que abordassem os desfechos de inflamação intestinal e/ou exacerbações pulmonares. O estudo de avaliação nutricional foi realizado através de levantamento de dados antropométricos e clínicos, além de questionários aplicados a pacientes e responsáveis sobre dados de consumo alimentar e características socioeconômicas. Na busca bibliográfica foram encontrados 48 diferentes estudos, e somente 6 atingiram os critérios para integrar a metanálise. Foi observado efeito protetor do uso de probióticos e simbióticos na taxa de exacerbação pulmonar em pacientes com fibrose cística quando comparados com placebo (OR= -1,01 (IC 95% -1,66; -0,37), p = 0,002). Os níveis de calprotectina fecal (indicador de inflamação intestinal) tiveram redução significativa após intervenção (OR= -12,18 (IC 95%: -22,50; -1,86), p = 0,02), e houve diminuição dos pacientes com inflamação intestinal (calprotectina > 50 mcg/g de fezes) com OR= 0,31 (IC 95%: 0,13; 0,79), p = 0,01. Na avaliação do perfil nutricional foram incluídos 101 pacientes (59,4% do gênero masculino, 86,4% caucasianos), e a mediana de idade na inclusão foi de 10 anos. A maioria dos pacientes foi classificada como eutrófica, com consumo alimentar adequado. Valores menores de escore Z de IMC foram observados em escolares e adolescentes, e a proporção de pacientes com peso abaixo do esperado aumenta de 10% entre pré-escolares para 35% na faixa etária escolar. As características socioeconômicas não demostraram relação com consumo alimentar ou estado nutricional. Os valores de função pulmonar foram mais baixos em adolescentes e indivíduos com pior estado nutricional, porém sem diferença significante. Dados da metanálise, apesar da limitação amostral, apontaram o uso de probióticos como fator de proteção para exacerbações respiratórias, bem como para inflamação intestinal. Resultados da avaliação nutricional indicam que a transição das faixas etárias pré-escolar para escolar é um momento crítico, portanto abordagens direcionadas para estas faixas etárias podem ser de grande importância para preservação da saúde nutricional. Sendo assim, recomenda-se que mais estudos de estratégias nutricionais preventivas sejam realizados em faixas etárias precoces, como suplementação de probióticos, visando a melhora do prognóstico de pacientes com fibrose cística. / Cystic fibrosis is a hereditary disease characterized by deficiency of chloride transportation in epithelial cell membranes, resulting in thick and abnormal mucus, which may obstruct ducts of exocrine glands in several organs. The main clinical manifestations include the respiratory (recurrent and chronic lung infections) and gastrointestinal systems (pancreatic insufficiency and consequent maldigestion and absorption of nutrients, resulting in malnutrition). There is evidence that intestinal microbiota composition may impact the respiratory tract colonization of individuals with cystic fibrosis. This study aimed to verify current evidence regarding the effects of supplementation of probiotics, prebiotics or both in cystic fibrosis patients, concerning gastrointestinal and respiratory outcomes. We performed a systematic review and meta-analysis, and additionally carried out a survey of the nutritional status of patients with cystic fibrosis attending the outpatient clinic of the Instituto da Criança HCFMUSP. The systematic review and meta-analysis was performed according to the protocol proposed by the Cochrane Collaboration, searching electronic databases using the terms \"prebiotics\" or \"probiotics\" or \"symbiotic\", and \"cystic fibrosis\". Randomized clinical trials addressing intestinal inflammation and/or pulmonary exacerbations were included. The assessment of nutritional status was carried out through a cross-sectional survey of medical records concerning clinical and anthropometric data, and also by applying a questionnaire to patients and caregivers concerning food consumption, and socioeconomic characteristics. The bibliographic search identified 48 different studies, but only 6 fulfilled criteria to be included in the meta-analysis. A protective effect of probiotic and symbiotic use was observed in the rate of pulmonary exacerbations when compared to placebo (OR = -1.01 (95%CI -1.66, -0.37), p=0.002). The levels of fecal calprotectin (indicator of intestinal inflammation) had a significant reduction after intervention (OR = -12.18 (95%CI: -22.50, -1.86), p=0.02) and there was a decrease in the proportion of patients with intestinal inflammation (calprotectin> 50 mcg/g feces) with OR = 0.31 (95%CI: 0.13, 0.79), p=0.01. Regarding nutritional assessment, 101 patients were included (59.4% male, 86,4% white race), and median age at inclusion was 10 years old. The majority of patients were considered to be eutrophic and have adequate food intake, but lower values of BMI Z-score were observed in schoolchildren and adolescents. The proportion of underweight patients increased from 10% among preschoolers to 35% of the school age group. The socioeconomic characteristics were not associated to the food consumption or nutritional status. Lung function was lower in adolescents and individuals with poor nutritional status, but without significant difference. Data from the meta-analysis, despite the limitations of sample size, indicated that the use of probiotics may be a protective factor for respiratory exacerbations as well as intestinal inflammation. Results of the nutritional assessment indicate that the transition from the pre-school to the school age groups is a critical period, and therefore approaches directed to these age groups may have a significant impact in the nutritional health. Towards that, further studies using preventive nutritional strategies such as probiotic supplementation, are recommended for younger age groups, aiming to improve the prognosis of patients with cystic fibrosis.

”Roligt men utmanande…” : Anestesisjuksköterskans erfarenheter av mötet med barn i förskoleåldern i samband med anestesiinduktion / The nurse anesthetist’s experiences of meeting with children of preschool age in connection with anesthesia induction

Franzén, Lisa, Tillaeus, Ylva January 2024 (has links)
Bakgrund: Forskning visar att barn upplever oro och rädsla i samband med anestesi. Anestesisjuksköterskan är en av de som behöver möta barnets känslor. Genom att belysa anestesisjuksköterskans erfarenheter kan förståelse skapas samt ge möjlighet till fördjupad kunskap inom barnanestesi. Syfte: Studiens syfte var att belysa anestesisjuksköterskans erfarenheter av mötet med barn i förskoleåldern i samband med anestesiinduktion. Metod: En kvalitativ metod med induktiv ansats genomfördes. Datainsamlingen bestod av semistrukturerade intervjuer där totalt tolv anestesisjuksköterskor intervjuades. Dataanalys genomfördes enligt Graneheim och Lundmans (2004) kvalitativa latenta innehållsanalys. Resultat: Två övergripande teman identifierades, med fyra kategorier och sju subkategorier. Det första temat, goda förutsättningar för ett vårdande möte, innefattar handlingar, strategier och faktorer som ger goda förutsättningar för att mötet med barn i förskoleåldern i samband med anestesiinduktionen ska bli vårdande. I det andra temat, hindrande faktorer för ett vårdande möte,lyfts anestesisjuksköterskans erfarenheter av vad som hindrar förutsättningarna för ett bra och vårdande möte.   Slutsats: Mötet med barn i samband med anestesiinduktionen är både utmanande och roligt. Anestesisjuksköterskan behöver anpassa sig efter det unika barnet, involvera föräldrar, tillämpa sina tidigare erfarenheter och inneha en handlingsberedskap för att kunna främja ett vårdande möte. Preoperativa förberedelser spelar en avgörande roll för såväl anestesisjuksköterskan, som för barn och föräldrar. Mötet kan dock ge upphov till känslomässig påfrestning då anestesisjuksköterskan kan behöva utföra tvingande handlingar vilka kan hindra förutsättningar för ett vårdande möte. / Background: Research shows that children experience worries, and fear associated with anesthesia. The nurse anesthetist’s is one of those who needs to meet the child’s feelings. By highlighting the nurse anesthetist’s experiences, understanding can be created and allow in-depth knowledge regarding pediatric anesthesia.  Aim: The study aimed to highlight the nurse anesthetist’s experiences of meeting with children of preschool age in connection with anesthesia induction  Method: A qualitative method with an inductive approach was used. The data collection consisted of semi-structured interviews where twelve nurse anesthetists were interviewed. The data analysis was carried out according to Graneheim and Lundmans (2004) qualitative latent content analysis. Results: Two overall themes were identified, with four categories and seven subcategories. The first theme, good presumptions for a caring meeting, includes actions, strategies and factors which gives good presumptions for the meeting with children of preschool age in connection with the anesthesia induction to turn out caring. In the second theme, obstructive factors for a caring meeting, the nurse anesthetist’s experiences of what obstructs the presumptions for a good and caring meeting are highlighted. Conclusion: The meeting with children in connection with the anesthesia induction is both challenging and fun. The nurse anesthetist needs to adapt to the unique child, involve the parent, apply their experiences, and have an action plan to promote a caring meeting. Preoperative preparations play a crucial role for the nurse anesthetist as well as for the child and parents. The meeting can give rise to emotional stress when the nurse anesthetist needs to perform coercive actions that obstruct the presumptions of a caring meeting.

Rozvoj myšlení a řeči jako oblast čtenářské pregramotnosti / Speech and thought development as part of reader preliteracy

Němcová, Nikola January 2019 (has links)
This diploma thesis focuses on the issues of thought and speech development in the area of reading preliteracy of preschool children. The thesis is divided into theoretical and empirical parts. The theoretical part is devoted to the issues of reading preliteracy, thought and speech development in the area of reading preliteracy, drawing attention to the risk of developing specific learning disabilities and discusses the impact of pre-school institutions on children. The empirical part is compiled based on this knowledge. The aim of the empirical part is to map the level of reading preliteracy in children aged 5 - 6 in Humpolec. Specific research questions investigate the preliteracy teaching skills of kindergarten teachers, as well as the way how teachers develop these reading skills and a range of tests for the subsequent evalution of reading preliteracy levels of children. The empirical part of the thesis combines two methods of data acquisition, questionnaire surveys and observation of children during the performance of tasks in the tests. There was a relatively good level of reading preliteracy among children aged 5 - 6, but with large individual differences among children. KEYWORDS children of preschool age, reader preliteracy, thought, speech, vocabulary, memory, attention
