No. of bitstreams: 1 Peterson_JoseCarlosBellini_M.pdf: 573106 bytes, checksum: 27eae8ac4d3d6adff5223f3ae8b46ffc (MD5) Previous issue date: 2007 / Resumo: O hipotireoidismo subclínico (HTSC) é uma enfermidade caracterizada pelo aumento dos níveis de hormônio tireoestimulante associado a níveis normais de tiroxina livre, habitualmente sem sinais e sintomas do hipotireoidismo clinicamente manifesto (HTC). A literatura mostra prevalência mais alta de HTSC em mulheres e nos mais idosos. No presente trabalho, estudou-se 76 mulheres portadoras de HTSC, com 65 anos ou mais, seguidas no Ambulatório de Endocrinologia da Faculdade de Medicina de Jundiaí, São Paulo. Foram excluídas mulheres com idade inferior a 65 anos, pacientes com diagnóstico prévio de HTC e HTSC em tratamento, Diabetes Mellitus ou outra endocrinopatia que possa cursar com elevação dos níveis lipídicos , hepatopatias, alcoolismo, nefropatias, tabagismo, uso de drogas hiperlipemiantes e pacientes com antecedentes de Doença Vascular Aterosclerótica (DVA). Avaliou-se: idade: 70.43 ± 4.84 anos; IMC: 27.52 ± 3.07 kg/m², pressão arterial sistólica (PAS): 136.97 ± 17.44 mmHg; pressão arterial diastólica (PAD): 87.89 ± 10.87 mmHg; tiroxina livre (T4L): 1.28 ± 0.25 ng/dl; hormônio tireo-estimulante (TSH): 12.41 ± 11.19 mIU/L; colesterol total (CT): 257.12 ± 61.22 mg/dl; HDL-colesterol (HDL-c): 39.30 ± 8.78 mg/dl; LDL-colesterol (LDL-c): 146.49 ± 42.94 mg/dl; VLDL-colesterol (VLDL-c): 41.13 ± 27.41 mg/dl e triglicérides (TG): 224.46 ± 123.30 mg/dl. Foi feito o estudo dos perfis clínico-laboratoriais presentes nesse grupo de pacientes, através da análise comparativa dos agrupamentos, que mostrou a existência de dois perfis: 1. Mulheres idosas com HTSC com maior valor de T4L e HDL-c e menor valor de TSH, CT, TG, LDLc, VLDL-c, CT/HDL-c e LDL/HDL-c; 2. Mulheres idosas com HTSC com valor menor de T4L e HDL-c e maior valor de TSH, CT, TG, LDLc, VLDL-c, CT/HDL-c e LDL/HDL-c. A aparente relação entre HTSC e dislipidemia resultou em uma elevada relação CT/HDL-c (p < 0.001) e também na relação LDL-c/HDL-c (p < 0.001) no subgrupo 2, o que traduz um risco cardiovascular aumentado, associado à DVA. Em conclusão, o estudo relaciona o HTSC em um grupo de mulheres idosas com a dislipidemia, mostrando dois perfis endócrinometabólicos, com risco de desenvolvimento de aterosclerose mais elevado naquele que apresenta menores valores de T4L e HDL-c / Abstract: Subclinical hypothyroidism (SCH) is a disease characterized by an increase in the thyrostimulating hormone (TSH), which is associated to normal levels of free thyroxin (FT4), which frequently does not present signs and symptoms of clinically manifested hypothyroidism. Literature reports a higher prevalence in women and elderly people. In this work, 76 elderly women with SCH were studied in the Endocrinology Clinic of FMJ - Jundiaí (São Paulo, Brazil), excluding patients in treatment to hypothyroidism and who presented other endocrinopathy or conditions that cause dyslipidemia. They were analyzed according to: Age (Average ± OR): (70.43±4.84), BMI (27.52±3.07), Systolic Blood Pressure (136.97±17.44), Diastolic Blood Pressure (87.89±10.87), FT4 (1.28±0.25), TSH (12.41±11.19), Total Cholesterol (TC) (257.12±61.22), HDL-c (39.30±8.78), LDL-c (146.49±42.94), VLDL-c (41.13±27.41) and Triglycerides (224.46±123.30). The clinical-laboratorial profiles present in this group was carried out through the clusters¿ comparative analysis, demonstrating the existence of two profiles: 1. Higher levels of FT4 and HDL-c and lower levels of TSH, CT, TG, LDL-c, VLDL-c, CT/HDLc and LDL/HDL-c; 2. Lower levels of FT4 and HDL-c and higher levels of TSH, CT, TG, LDL-c, VLDL-c, CT/HDL-c and LDL/HDL-c. The apparent relationship between SCH and dyslipidemia resulted in a high CT/HDL-c (p<0.001) and LDL-c/HDL-c (p<0.001) ratios in subgroup 2, which implies in increased cardiovascular risk, due to atherosclerotic vascular disease (AVD). In conclusion, this study relates SCH with dyslipidemia in a group of elderly women, revealing two endocrine-metabolic profiles, in which that with smaller FT4 and HDL-c levels presents a higher risk of developing atherosclerosis / Mestrado / Gerontologia / Mestre em Educação

Habilidades do desenvolvimento em crianças com hipotireoidismo congênito: enfoque na comunicação / Development skills in children with congenital hypothyroidism: focus on communication

Mariana Germano Gejão 28 November 2006 (has links)
O hipotireoidismo congênito, uma das alterações do metabolismo detectadas por meio da triagem neonatal, pode acarretar alterações no desenvolvimento global do indivíduo. O objetivo deste estudo foi traçar o perfil das habilidades do desenvolvimento em crianças com hipotireoidismo congênito e verificar possíveis influências dos dados da história clínica no perfil traçado. Foram avaliadas, por meio da Early Language Milestone Scale e do Inventário Portage Operacionalizado, 35 crianças (23 do gênero feminino e 12 do masculino) com hipotireoidismo congênito detectado pela triagem neonatal. As crianças pertenciam à faixa etária de 2 a 36 meses e realizavam tratamento com reposição hormonal há pelo menos um mês. Os dados da história clínica foram obtidos por meio de entrevista com os responsáveis legais pelas crianças e análise de prontuário. Na avaliação por meio da Early Language Milestone Scale, 11 crianças apresentaram desempenho alterado na função auditiva expressiva, 2 na função visual e 1 na função auditiva receptiva. Na avaliação por meio do Inventário Portage Operacionalizado, 7 crianças apresentaram desempenho alterado na área da linguagem, 5 na área cognitiva, 4 nas áreas motora e social e 3 na área de autocuidados. Não foram observadas influências dos dados da história clínica no resultado obtido. Concluiu-se que a maioria das crianças avaliadas neste estudo apresentou desempenho adequado para as habilidades avaliadas. Paras as crianças com desempenho alterado, observou-se maior déficit na área de linguagem, principalmente no que diz respeito aos aspectos expressivos e na área cognitiva. Não ficou provada a influência dos dados da história clínica no perfil traçado para as habilidades do desenvolvimento. Entretanto, observou-se tendência para desempenho adequado nas habilidades avaliadas entre as crianças que realizaram a triagem neonatal, receberam o diagnóstico e iniciaram o tratamento para o hipotireoidismo congênito mais precocemente e que receberam dosagem de levotiroxina mais elevada no início do tratamento. / The congenital hypothyroidism, one of the metabolism alterations detected through the neonatal screening, may cause alterations in the individual\'s global development. The objective of this study was to draw the profile of the development skills in children with congenital hypothyroidism and verify possible influences of the clinical history data in the drawn profile. It had assessed, through Early Languagem Milestone Scale and Inventário Portage Operacionalizado, 35 children (23 of the feminine gender and 12 of the masculine) with congenital hypothyroidism detected by the neonatal screening. The children belonged to the age group from 2 to 36 months and accomplished treatment with hormonal replacement for at least one month. The clinical history data were obtained through interview with the legal responsible for the children and handbooks analysis. In assessement through Early Languagem Milestone Scale, 11 children presented altered performance in auditory expressive function, 2 in visual function and 1 in auditory receptive function. In assessement through the Inventário Portage Operacionalizado, 7 children presented altered performance in the language area, 5 in cognitive area, 4 in motor and social areas and 3 in self-care area. Influences of the clinical history data were not observed in the obtained result. It was concluded that most of the assessed children in this study presented adequate performance for the evaluated skills. For the children with altered performance, larger deficit was observed in language area, mainly in expressive aspects and cognitive area. The influence of the clinical history data was not proven in the profile drawn for the development skills. However, tendency for appropriate performance in the assessed skills was observed among the children that accomplished the neonatal screening, received the diagnosis and began the treatment for the congenital hypothyroidism earlier and that received higher dose of thyroxine in the beginning of the treatment.

Este estudo objetivou verificar aspectos epidemiológicos e caracterizar o estado nutricional relativo aos micronutrientes em indivíduos com SD. Os aspectos epidemiológicos foram verificados por meio de prontuários dos indivíduos com SD, assistidos em Juiz de Fora (MG), entre 2004-2008. Para análise dos micronutrientes, indivíduos com SD (9,7±3,4 anos) foram distribuídos em eutireoidianos (n=10) e hipotireoidianos (n=10) e o grupo controle (8,9±2,8 anos, n=34) foi selecionado entre escolares, pareados por sexo e idade. As quantificações de selênio, zinco, cobre, ferro e magnésio no soro foram realizadas por espectrometria de absorção atômica. A prevalência de SD foi 16,6/10.000 nascidos vivos. Dos 235 indivíduos com prontuários avaliados, 50,6% eram do sexo masculino, 18,8% apresentavam disfunções tireoidianas e 31,1% eram cardiopatas. Os indivíduos com SD apresentaram níveis séricos de selênio (38,6±10,5 μg/L), zinco (64,7±11,8 μg/dL) e cobre (110,9±20,7 μg/dL) significativamente diferentes do grupo controle (49,7±10,2 μg/L; 75,2±18,1 μg/dL e 100,4±17,1 μg/dL, respectivamente). Não foram observadas diferenças nos níveis de ferro e de magnésio entre os indivíduos com SD e o grupo controle, bem como nos níveis dos micronutrientes avaliados entre os indivíduos com SD (eutireoidianos e hipotireoidianos). A prevalência de SD se assemelhou ao descrito para o Brasil e a América Latina. Alterações nos níveis de selênio, zinco e cobre foram observadas nos indivíduos com SD, no entanto, não se correlacionaram ao desenvolvimento de hipotireoidismo nesta população. / Subjects with Down syndrome (DS) often develop some comorbidities, including hypothyroidism, and this fact may be related to changes in micronutrient serum levels. The aim of this study was determine the epidemiological profile and characterize the nutritional status of micronutrients in DS subjects. The epidemiological profile was determined by the analysis of DS patient medical records, treated in Juiz de Fora (MG, Brazil), from 2004-2008. For the analysis of micronutrients, DS subjects (9.7±3.4 years) were distributed in euthyroid (n=10) and hypothyroid (n=10) and the control group (8.9±2.8 years, n=34) was selected from students, matched by sex and age. Serum levels of selenium, zinc, copper, iron and magnesium were quantified using atomic absorption spectrometry. DS prevalence was 16.6/10,000 live births. Of the 235 DS subjects, 50.6% were male, 18.8% had thyroid dysfunction and 31.1% had congenital heart defects. DS subjects had serum levels of selenium (38.6±10.5 μg/L), zinc (64.7±11.8 μg/dL) and copper (110.9±20.7 μg/dL) significantly different from the control group (49.7±10.2 μg/L, 75.2±18.1 μg/dL and 100.4±17.1 μg/dL, respectively). There were no significant statistical differences between these groups in the serum levels of iron and magnesium, as well as in the serum levels of micronutrients assessed among individuals with DS (euthyroid and hypothyroid). The estimated prevalence of DS was similar to the values described for Brazil and Latin America. Altered serum levels of selenium, zinc and copper were observed in DS, but they did not relate to hypothyroidism in this population.

Dessa forma, o objetivo desse estudo foi avaliar a integridade do reflexo pressor do exercício físico em mulheres com HSC. MÉTODOS: Foram avaliadas dezoito mulheres com HSC (Grupo HSC) e vinte mulheres eutiroidianas (Grupo Controle), pareadas por idade (37 ± 11 vs. 38 ± 11 anos, p=0,907, respectivamente), índice de massa corporal (26 ± 5 vs. 24 ± 4 kg/m2, p=0,221, respectivamente) e nível de atividade física (6,93 ± 0,81 vs. 7,66 ± 1,14, p=0,063, respectivamente). A pressão arterial foi medida minuto a minuto pelo método oscilométrico (DIXTAL2023®), a frequência cardíaca medida continuamente pelo eletrocardiograma (DIXTAL2023®) e o fluxo sanguíneo do antebraço pela técnica de pletismografia de oclusão venosa (Hokanson®). A condutância vascular do antebraço foi calculada pela divisão do fluxo sanguíneo do antebraço pela pressão arterial média, multiplicada por 100. Registrando essas variáveis por 3 minutos de basal seguidos de 3 minutos de exercício físico, foram realizados os protocolos de exercício físico passivo, exercício físico isométrico a 10% da contração voluntária máxima do antebraço, exercício físico a 30% da contração voluntária máxima do antebraço e por 2 minutos oclusão circulatória pós-exercício físico isométrico a 30%. ANOVA de dois fatores foi utilizada para testar as diferenças, adotando significativo p<0,05. RESULTADOS: Durante o exercício físico passivo, a pressão arterial sistólica, diastólica e média sofreram diminuição significativa, porém semelhante entre os grupos HSC e Controle. A frequência cardíaca, o fluxo sanguíneo do antebraço e a condutância vascular do antebraço não apresentaram modificações ao longo do protocolo de exercício físico passivo. Durante o exercício físico de leve intensidade a pressão arterial sistólica não sofreu nenhuma alteração, a pressão arterial diastólica foi significativamente diferente entre os grupos HSC e Controle. Os valores da pressão arterial média, frequência cardíaca, fluxo sanguíneo do antebraço e condutância vascular do antebraço apresentaram aumento significativo e se comportaram similarmente. Durante o exercício físico de moderada intensidade os valores de pressão arterial sistólica, diastólica, média, fluxo sanguíneo do antebraço e condutância vascular do antebraço aumentaram significativamente e similarmente entre os grupos HSC e Controle. Entretanto a frequência cardíaca apresentou comportamento significativamente diferente entre os grupos HSC e Controle, porém, ambos os grupos apresentaram aumento significativo da frequência cardíaca em relação aos valores basais. Para a oclusão circulatória, os grupos sofreram aumento da pressão arterial sistólica, diastólica e média, porém com comportamento similar. CONCLUSÃO: Mulheres com HSC apresentam reflexo pressor do exercício físico íntegro. / INTRODUCTION: Patients with subclinical hypothyroidism (SCH) may show changes in the cardiovascular system. Thus, the aim of this study was to evaluate the integrity of the pressor reflex exercise in women with SCH. METHODS: Were evaluated eighteen women with SCH (Group SCH) and twenty euthyroid women (Group Control), matched for age (37 ± 11 vs. 38 ± 11 years; p=0.907, respectively), body mass index (26 ± 5 vs. 24 ± 4 kg/m2; p=0.221, respectively) and level of physical activity (6,93 ± 0,81 vs. 7,66 ± 1,14, p=0,063, respectively). Blood pressure was measured every minute by oscillometry (DIXTAL2023®), heart rate measured continuously by electrocardiogram (DIXTAL2023®) and forearm blood flow by the technique of venous occlusion plethysmography (Hokanson®). In forearm vascular conductance was calculated by dividing the forearm blood flow by the mean arterial pressure multiplied by 100. Registering these variables from baseline for 3 minutes followed by 3 minutes of exercise, the protocols of passive exercise, isometric exercise at 10% of maximal voluntary contraction of forearm exercise at 30% maximal voluntary contraction of the forearm were performed and circulatory occlusion for 2 minutes post-isometric physical exercise to 30%. Two-factor ANOVA was used to test differences, significant considering p< 0.05. RESULTS: During the passive exercise, systolic blood pressure, diastolic and mean suffered significant decline, but similar between SCH and Control groups. The heart rate, forearm blood flow and vascular conductance of the forearm showed no change during the protocol of passive exercise. During mild exercise systolic blood pressure did not undergo any changes, diastolic blood pressure was significantly different between the SCH and Control groups. The values of mean arterial pressure, heart rate, forearm blood flow and vascular conductance of the forearm showed a significant increase and behaved similarly. During exercise of moderate intensity values of systolic, diastolic, mean, forearm blood flow and vascular conductance of the forearm increased significantly and similarly between SCH and Control groups. However, the heart rate behavior was significantly different between the SCH and Control groups, however, both groups showed a significant increase in heart rate from baseline. To circulatory occlusion groups had an increase in systolic blood pressure, diastolic and mean, but with similar behavior. CONCLUSION: Women with SCH have pressor reflex upright exercise.

A diminuição na produção ou ausência de hormônios tireoidianos leva à patologia denominada hipotireoidismo e quando essa alteração está presente desde o nascimento, denomina-se hipotireoidismo congênito. Nesses casos, a literatura aponta que crianças com hipotireoidismo congênito podem apresentar, entre várias alterações, dificuldades nas habilidades motoras finas e no desenvolvimento da linguagem. O objetivo geral do estudo foi avaliar as habilidades motoras finas e da função expressiva da linguagem de crianças com hipotireoidismo congênito, e investigar se há associação entre habilidades motoras finas e função expressiva da linguagem. Trata-se de um estudo prospectivo de uma coorte de crianças com hipotireoidismo congênito, diagnosticadas e acompanhadas em um serviço de referência em triagem neonatal de um hospital público e de crianças sem essa disfunção. A triagem foi realizada por meio das Escalas Bayley de Desenvolvimento Infantil III, nos domínios específicos cognitivo, motor grosso e fino e de linguagem receptiva e expressiva. O desempenho das crianças foi expresso em três categorias: competente, de risco e não competente. Foram triadas 117 crianças com Hipotireoidismo Congênito diagnosticado ao nascimento, mas com o nível de TSH normalizado no momento da triagem, e 51 sem essa disfunção, com idade média de 21 meses. As crianças com Hipotireoidismo Congênito apresentaram um desempenho pior nas habilidades motora fina e de linguagem, demonstrando uma associação entre essas duas habilidades. Quando realizada a associação entre os dois grupos, com e sem hipotireoidismo congênito, a associação persiste no grupo exposto à alteração endócrina, demonstrando assim que a inter-relação das habilidades está presente em todos os indivíduos, além de apresentarem 2 vezes mais chances de alterações quando a motricidade fina já estiver comprometida. Sendo assim, conclui-se com este estudo que o desenvolvimento de ambas as habilidades, linguagem expressiva e motricidade fina, podem estar associadas e/ou dependentes uma da outra / Abstract: The thyroid is an endocrine gland responsible for producing hormones and their function is to synthesize thyroid hormones essential for the development and growth of various organs and systems in humans, since intrauterine life until the second year of life. The decrease in production or absence of thyroid hormones leads to disease called hypothyroidism and when this change is present since birth is called congenital hypothyroidism. In such cases, the literature indicates that children with congenital hypothyroidism may present, among several changes, difficulties in fine motor skills and language development. The overall objective of the study was to assess the fine and expressive function of children with congenital hypothyroidism language motor skills, and investigate whether there is an association between fine motor skills and expressive language function. This is a prospective study of a cohort of children with diagnosed and monitored in a reference service in a public hospital neonatal screening for congenital hypothyroidism and children without this disorder. The screening was performed using the Bayley Scales of Infant Development III in specific cognitive domains, gross and fine motor and receptive and expressive language. The children's performance was expressed in three categories: competent, risk and not competent. 117 children diagnosed with Congenital Hypothyroidism at birth were screened, but the TSH level normalized during screening, and 51 without such dysfunction, with a mean age of 21 months. Children with Congenital Hypothyroidism showed a worse performance in fine motor and language skills, demonstrating an association between these two skills. When the association between the two groups was done, it continued exposed in the endocrine alteration group, demonstrating that the interrelationship of skills is present in all individuals, besides having 2 times more likely a chance when the fine motor is already compromised. Therefore, it is concluded from this study that the development of both skills, motor skills and expressive language, might be associated and / or dependent on one another / Mestrado / Interdisciplinaridade e Reabilitação / Mestra em Saúde, Interdisciplinaridade e Reabilitação

Vztah hmotnosti a BMI k dávce levotyroxinu nemocných s hypotyreózou / Weight and BMI in relation to the dose of levotyroxin of patients with hypothyreosis

Radiměřská, Veronika January 2017 (has links)
The objective of this study was to define if there is a mutual influence between the daily dose of levothyroxine, positivity/negativity of thyroid antibody, BMI, waistline, hip measurement and other anthropometric parameters. It was also to analyze if the daily dose of levothyroxine is being influenced by degree of hypothyroidismimportance. Methodology: There were 44 patients examined having hypothyroidism and who have been cured with levothyroxine so that their thyroid function has been normal at the time. I have examined those patients' body height, weight, BMI, waistline and hipline. Under the supervision of the medicine doctor I used records available for each of patients regarding concentration of TSH, TPOAb and TgAb, which were defined with patients' blood by a method of immunoassay. Results: The average daily dose of levothyroxine in all patients sample has showed a positive correlation with BMI (Spearman rho coef. 0,429, P value=0,004) and with waistline of women (Spearman rho coef. 0,332, P value=0,028). The concentration of thyroidantibody did not show a statistical relevance regarding the dependence with the dose of levothyroxine, BMI or other anthropometric parameters.The highest average daily dose of levothyroxine was confirmed for examined patients after total thyroidectomy (median of...

Regulation of Adipocyte Lipolysis by TSH and its Role in Macrophage Inflammation

Durand, Jason AJ January 2012 (has links)
Elevated Thyroid-Stimulating Hormone (TSH) is associated with an increased risk of cardiovascular disease (CVD). We hypothesized that TSH-stimulated FA release from adipocytes contributes to macrophage inflammation. 3T3-L1 and human subcutaneous differentiated adipocytes were treated with TSH for 4 hours under various conditions and lipolysis assessed via glycerol secretion. Optimal conditions were determined and protein expression of ATGL, HSL and perilipin remained stable. TSH-stimulated 3T3-L1 or human adipocyte-conditioned medium (T-ACM) was placed on murine J774 or human THP-1 macrophages, respectively, and macrophage cytokine mRNA levels (IL-1β, IL-6, MCP-1, and TNFα) were measured by real-time RT-PCR. T-ACM did not change cytokine mRNA expression in J774 macrophages or THP-1 macrophages when compared to ACM. Absence of BSA in the medium may have hindered release of FA from differentiated adipocytes into the medium, BSA may be required to permit adequate FA accumulation in the medium to then evaluate the effect of T-ACM on macrophages. Further investigation is required to determine the effect of FA on J774 and THP-1 inflammatory response.

Extra-Thyroidal Action of TSH on Adipocyte Insulin Signaling

Felske, David January 2015 (has links)
In subclinical hypothyroidism (SH), high levels of circulating thyroid stimulating hormone (TSH) maintain normal thyroid hormone levels, despite mild thyroid failure. SH is associated with cardiovascular disease and insulin resistance, although the underlying pathophysiology is not fully understood. We hypothesized that TSH may inhibit insulin action in adipocytes. To investigate this relationship, we studied primary human differentiated adipocytes. Abdominal subcutaneous adipose tissue samples were obtained (approved by OHSN-REB) from 16 weight-stable patients undergoing elective abdominal surgery. We stimulated adipocytes differentiated from stromal preadipocytes with 5 mU/ml TSH and/or 100 nM insulin, and assessed acute insulin signaling, lipogenesis and glucose uptake. Immunoblot analysis revealed that TSH suppressed insulin-stimulated Akt phosphorylation by 45% (n=5; p = 0.01). When adipocytes were pre-incubated with conventional protein kinase C (cPKC) inhibitor Gö6976, TSH inhibition was blocked. Our data indicate that TSH inhibits insulin-stimulated lipogenesis (up to 37%), but depends on BMI. Insulin-stimulated glucose uptake was enhanced by 36% and also correlated with BMI. This data suggests that TSH can modulate adipocyte insulin signaling.

Disorders in neurodevelopment arising from subclinical and often not-detectable maternal thyroid dysfunction share similarities with some of the cognitive and behavior alterations manifested in autism spectrum disorders (ASD). In particular, fetal deficits in cortical migration, neuronal fate and maturation impair fine aspects of cognitive function and social behavior in these social and clinical conditions. To date however, there are very few studies, which address in detail the predominant deficits in communication and sociability in late-adolescence and young adult individuals regarding their sex differences related to subclinical maternal hypothyroidism during pregnancy. Using an animal model of mild maternal hypothyroidism, we investigated social behaviors of the offspring after puberty in both male and female mice and looked for changes in their anxiety and aggression levels and vocalization as well as their sex dependence. Our study showed an increase in induced anxiety paralleled by relatively reduced vocalization in male offspring subjected to mild hypothyroidism in pregnant female mice. These experimental findings not only open a neurodevelopmental window to investigate the molecular aspects of these behavioral abnormalities but also and may foster educational, psychological and medical advances in late-stage child neurodevelopment among the ASD individuals / A disfunção tireoidiana materna com destaque no hipotireoidismo causa representativos danos neurológicos para o feto que em muitos aspectos cognitivos se assemelham às alterações neurobiológicas das doenças do espectro autista, como exemplo: alterações de migração cortical, comprometimento de especialização neuronal e modificações nas funções cognitivas. Há uma escassez de estudos para melhor esclarecer e caracterizar as alterações de comportamento na prole pós-puberal, cujo impacto no neurodesenvolvimento intra-útero ocorrera facilitando os prejuízos tardios de sociabilidade animal. Utilizando um modelo murino de hipotireoidismo materno (tratamento com metimazol), estudamos as alterações em comportamentos sociais da prole após o período puberal, a fim de entendermos os variados aspectos de prováveis alterações cognitivas e motivacionais em machos versus em fêmeas. Realizamos o estudo com foco em comportamentos vislumbrando agressividade ofensiva e defensiva, vocalização social, e autopreservação (i.e.; medo; ansiedade) bem como, adaptações neurovegetativas (i.e.; regulação térmica). Os dados mostraram um acometimento da prole masculina proveniente de mães tratadas com metimazol 30 dias antes da gestação ocorrer. Esse projeto correlacionou aspectos etológicos com um grande tema da esfera clínica em humanos no que tange doenças do neurodesenvolvimento e desarranjos sociais mais brandos, porém abrangentes e prevalentes e suas repercussões comportamentais na vida pós-puberal e adulta.

Hur personer med hypotyreos upplever sin livskvalité

Öhman, Johanna, Jonsson, Isabelle January 2019 (has links)
Bakgrund: Hypotyreos är en av de vanligaste endokrina sjukdomarna. Varje år insjuknar människor i sjukdomen och vanligast är att kvinnor drabbas. Att drabbas av hypotyreos innebär att man har brist på tyreoideahormoner i sköldkörteln och att energiproduktionen går på sparläge. Kompetenskrav sätts på sjuksköterskan i vårdandeprocessen hos patienter med hypotyreos då konsekvenserna av sjukdomen kan förefalla diffusa och svåra att mäta. Syfte: Syftet med denna studie var att beskriva hur personer med hypotyreos upplever sin livskvalité.  Metod: Denna studie är en beskrivande litteraturstudie. Elva artiklar med både kvalitativ och kvantitativ ansats har analyserats och delats upp i teman och subteman. Huvudresultat: Personer med hypotyreos upplevde varken en bättre livskvalitet eller förbättringar gällande sköldkörtelrelaterade symtom trots att de medicinerats. Känslan hos dessa personer var att de kände sig svaga, orkeslösa, dränerade på ork och att deras dagliga aktiviteter begränsades. En känsla av missförståelse upplevdes inom vården då läkarna fokuserade främst på personernas provresultat. Trots det att läkaren talade om att blodvärdena låg inom referens upplevde personerna med hypotyreos att flertalet symtom kvarstått. Slutsats: Personer med hypotyreos uttrycker missnöje över sin upplevelse av livskvalitet, sin medicinering och även vårdrelationen. Att leva med hypotyreos innebär att man kan ha kvarvarande symtom trots medicinering och livskvalitén för dessa personer påverkas negativt. Genom en ökad förståelse för denna komplexa sjukdom skulle sjuksköterskan kunna bidra med en större trygghet och hjälpa dessa personer genom att skapa en bättre vårdrelation. / Background: Hypothyroidism is one of the most common endocrine diseases. Every year, people get sick with the disease and most commonly, women are affected. Being affected by hypothyroidism means that there is a lack of thyroid hormones in the thyroid gland and makes the energy production goes to a low saver. Competence requirements are imposed on the nurse in the caring process of patients with hypothyroidism as the consequences of the disease may appear diffuse and difficult to measure. Purpose: The purpose of this study was to describe how people with hypothyroidism experience their quality of life. Method: This study is a descriptive literature study. Eleven articles with both qualitative and quantitative design have been analyzed and divided into themes and sub-themes. Main Results: People with hypothyroidism experienced neither a better quality of life nor improvements in thyroid-related symptoms despite being medicated. The feeling of these people was that they felt weak, powerless, drained of energy and that their daily activities were limited. A feeling of misunderstanding was experienced in health care when the doctors focused mainly on the person's test results. Although the doctor mentioned that the blood values were within reference, people with hypothyroidism felt that a number of symptoms remained. Conclusion: People with hypothyroidism express dissatisfaction with their experience of quality of life, their medication and even the care relationship. Living with hypothyroidism means that you may have remaining symptoms despite medication and the quality of life for these people is adversely affected. Through an increased understanding of this complex illness, the nurse could contribute with greater security and help these people by creating a better care relationship.
