Abstract
BACKGROUND Neurofibromatosis type 1 (NF1) is a rare genetic disorder with a wide range of clinical manifestations, notably neurocutaneous features, that can lead to emotional and physical consequences. OBJECTIVES This study assessed the influence of sociodemographic factors and clinical features of the disease on the quality of life of Brazilian individuals with NF1. METHODS This is a descriptive cross-sectional study. Data were collected from 101 individuals with NF1 using the Brazilian version of the Impact of NF1 on Quality of Life Questionnaire (INF1-QoL), a form with information on sociodemographic characteristics, and an NF1 visibility self-evaluation scale. The relationship between variables was evaluated through statistical testing, and the significance level was defined as 0.05. RESULTS The study included 101 adults with NF1 aged 18 to 59 years, with a mean age of 35.54 years (±9.63) and a female predominance (n = 84, 83.17%). The mean total INF1-QoL score was 10.62 (±5.63), with a median of 10, minimum value of 0, and maximum of 31 points. Two characteristics of the participants were significantly associated with the quality of life: educational level (p = 0.003) and familial history of NF1 (p = 0.019). There was a statistically significant correlation between the INF1-QoL score and the degree of disease visibility (rho = 0.218; p = 0.028). STUDY LIMITATIONS Cross-sectional study, conducted with a convenience sample and using self-reported measures. CONCLUSIONS The findings support the significant impact of NF1 on quality of life. The authors recommend multidisciplinary follow-up for patients, with adherence to anticipatory clinical care measures, adequate pain control, psychological assistance, and genetic counseling.

Abstract
This study aimed to determine the antibiotic profile of microorganisms isolated from urine samples of patients with community urine tract infections (UTI) admitted to the University Hospital of the Federal University of Sao Carlos to support an appropriate local empirical treatment. A retrospective cross-sectional study was conducted from October 2018 to October 2020. Data from 1,528 positive urine cultures for bacterial pathogens and antibiograms were tabulated. Bacterial species prevalence and their resistance profile were analyzed and compared by sex and age. For Gram-negative fermenting bacteria, resistance rates were compared between patients with previous hospitalization and the total of infections caused by this group. For comparisons, the Chi-square test was performed, using Fisher's exact test when necessary (BioEstat program, adopting p ≤ 0.05). A multivariate analysis was applied to assess the effect of the studied variables in predicting multidrug resistance. Infections were more prevalent in women and older adults. Gram-negative bacteria represented 90.44% of total cultures. In both sexes, E. coli prevalence was significantly higher in adults compared with older adults (p < 0.0001). For several antibiotics, resistance rates were higher in the older adults compared with other ages and in patients with Gram-negative fermenting infections and previous hospitalization compared with the total of infections by this group of bacteria. The closer to the hospitalization, the higher the number of antibiotics with superior resistance rates. Resistance rates for aminoglycosides, carbapenems, ceftazidime, nitrofurantoin, piperacillin+tazobactam, and fosfomycin were less than 20%, considered adequate for empirical treatment. Only hospitalization in the previous 90 days was statistically significant in predicting infections by multidrug-resistant bacteria.

Abstract
This cross-sectional and descriptive study examined the family quality of life (FQoL) among 72 Brazilian families who have children with Williams syndrome, a rare genetic disorder in which most individuals have an intellectual disability, usually mild. Data were collected using sociodemographic and clinical data forms and the Beach Center FQoL Scale. The overall FQoL score was 3.90 ± 0.45, below the limit of four points considered satisfactory. Families felt more satisfied with the family interaction (4.11 ± 0.57), parenting (4.07 ± 0.42), and disability-related support (3.94 ± 0.62) domains, and less satisfied with the family's emotional (3.49 ± 0.73) and physical/material well-being (3.73 ± 0.74) domains. Paternal education, children's cardiopathy and autonomy in activities of daily living explained 24.5% of the variance in the overall FQoL. Measures are necessary to improve the emotional and physical/material well-being of families to reduce the family burden. Monitoring the child's cardiac condition and promoting independence in activities of daily living are also the main procedures.

Abstract
BACKGROUND Down syndrome (DS) is a non-rare genetic condition that affects approximately 1 in every 800 live births worldwide. Further, it is associated with comorbidities, anatomical alterations of the respiratory tract, and immunological dysfunctions that make individuals more susceptible to respiratory infections. OBJECTIVE To systematize the current scientific knowledge about the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among individuals with DS. DESIGN AND SETTING This integrative review was conducted at the Universidade Federal de São Carlos, São Paulo, Brazil. METHODS This review was conducted in the following databases: the Virtual Health Library (Biblioteca Virtual em Saúde, BVS), PubMed, and Web of Science, using MeSH descriptors. The search included English or Portuguese studies published between January 1, 2020, and October 14, 2022. RESULTS A total of 55 articles from 24 countries were selected, comprising 21 case-control or cohort studies, 23 case reports or series, and 11 narrative reviews or opinion studies. The articles were grouped into five categories: previous comorbidities, coronavirus disease 2019 (COVID-19) clinical features and evolution, cytokine storm and interleukins, living in institutions as a risk factor, and behavioral actions as a protective factor against SARS-CoV-2 infection. CONCLUSION Individuals with DS are more susceptible to COVID-19 infection due to variables such as previous comorbidities, immunological factors, and their habitable environments. These aspects confer a higher risk of infection and an unfavorable clinical course. The precise pathways involved in the pathophysiology of COVID-19 in individuals with DS are not clear, thus requiring further studies.

Abstract
This study aimed to assess the Family Quality of Life (FQoL) of Brazilian families with male children with Fragile X syndrome (FXS). Data from 53 families were collected using forms that included sociodemographic and clinical information, as well as the Beach Center Family Quality of Life Scale, a 5-point Likert scale ranging from "very dissatisfied" (1) to "very satisfied" (5). The mean overall FQoL score was 3.56 ± 0.79; the emotional well-being domain had the lowest score (2.98 ± 1.11) and showed significant differences between the other domains: family interaction (3.81 ± 0.89; p < 0.001), parenting (3.66 ± 0.89; p < 0.001), physical and material well-being (3.48 ± 0.83; p < 0.001), and disability-related support (3.75 ± 0.98; p < 0.001). Physical and material well-being was the second-lowest domain and was statistically different from the family interaction domain (p = 0.013). Lower FQoL satisfaction ratings were found in families with children who had difficulty getting along with people of the same age (t(51) = -3.193, p = 0.002; d = 1.019) and difficulty in living together on a day-to-day basis (t(51) = -3.060, p = 0.004; d = 0.888). These results highlight the importance of proper emotional support for the family, emphasizing the need to provide assistance not only for individuals with FXS but also for other family members. Besides, we advocate for the adoption of public policies that provide financial assistance to families and the implementation of the Brazilian Policy of Comprehensive Care for People with Rare Diseases.

Abstract
Sickle cell disease is the most common hemoglobinopathy among humans. As the condition promotes susceptibility to infections, chronic inflammation, and hypercoagulability disorders, several international agencies have included individuals with this disease in the COVID-19 risk group for severe outcomes. However, available information about the subject is not properly systematized yet. This review aimed to understand and summarize the scientific knowledge about the impact of SARS-CoV-2 infection in patients with sickle cell disease. Searches were performed in the Medline, PubMed, and Virtual Health Library databases based on descriptors chosen according to the Medical Subject Headings. We analyzed studies published between 2020 and October 2022, developed with qualitative, quantitative, or mixed methodology, and written in English, Spanish, or Portuguese. The search resulted in 90 articles organized into six categories. There is disagreement in the literature about how different aspects related to sickle cell disease, such as chronic inflammation status, hypercoagulability, hemolytic anemia, use of hydroxyurea, and access to medical care interference with the clinical course of COVID-19. These topics deserve further investigation. It is evident, however, that the infection may manifest in an atypical way and act as a trigger for the development of sickle cell-specific complications, such as acute chest syndrome and vaso-occlusive crises, conditions that are associated with great morbidity and mortality. Therefore, healthcare professionals must be aware of the different forms of presentation of COVID-19 among these individuals. Specific guidelines and therapeutic protocols, as well as public policies for sickle cell individuals, must be considered. Systematic review registration This review (https://doi.org/10.17605/OSF.IO/NH4AS) and the review protocol (https://osf.io/3y649/) are registered in the Open Science Framework platform.

Abstract
This exploratory cross-sectional study aimed to examine the family quality of life (FQoL) among 51 Brazilian families who have children with Rubinstein-Taybi syndrome, a rare genetic disorder. Data were collected using sociodemographic and clinical data forms, as well as the Beach Center FQoL Scale, a 5-point Likert scale ranging from "very dissatisfied" (1) to "very satisfied" (5). The average score of the overall FQoL was 3.93 ± 0.64. Families' scores were higher for family interaction (4.17 ± 0.76), parenting (4.13 ± 0.61), and disability-related support (4.08 ± 0.76) domains, and lower for the family's emotional well-being (3.31 ± 0.96) and physical/material well-being (3.76 ± 0.82) domains. Family income, attendance at religious services, presence of ocular abnormalities, and aggressive behavior explained 46.2% of the variance in the overall FQoL. In summary, FQoL seems to be anchored in aspects such as family interaction and the care of parents, and be negatively affected by emotional issues, physical, and material limitations. In this context, psychological assistance should be provided to both parents and siblings whenever indicated, for improving emotional well-being and increasing family resilience. Additionally, investments in social policies, services, and human and material resources are needed to improve the physical and material conditions of families, promote better health care, and therefore reduce the family burden.

Abstract
BACKGROUND Intellectual disability (ID) and autism spectrum disorder (ASD) are often concomitant childhood developmental disorders. These disorders can alter family quality of life (FQoL). OBJECTIVE To investigate FQoL among families who have children with mild ID, associated with mild ASD. METHODS Cross-sectional descriptive study with 69 families who have children with mild ID and ASD, ranging from six to 16 years old, and who were provided with disability-related services in Brazil. Data were collected using a family sociodemographic questionnaire, an ID and ASD personal profile form, the Barthel index for activities of daily living and the Beach Center FQoL scale. RESULTS People with ID and ASD had an average score of 88.2±11.5 in the Barthel index, thus indicating moderate dependency in basic activities of daily living. The average total FQoL score (3.56±0.34) was lower than the scores for the "family interaction" (3.91±0.42; p<0.001), "parenting" (3.79±0.35; p<0.001) and "disability-related support" (3.98±0.16; p<0.001) domains; and higher than the scores for the "physical/material well-being" (3.19±0.64; p<0.001) and "emotional wellbeing" (2.75±0.62; p<0.001) domains. Parents' marital condition, monthly family income, family religious practice and effective communication skills among the people with ID and ASD were predictors for FQoL (R2=0.407; p<0.001). CONCLUSIONS FQoL was sustained through factors such as family interaction and parents' care for their children. Improving families' emotional wellbeing and physical and material conditions is likely to positively affect the FQoL of these families.

Abstract
With this research, we aimed to raise elements to enhance the understanding of alcohol consumption among pregnant women in Brazil. Fourteen women identified as alcohol consumers during pregnancy were interviewed. Alcohol consumption during pregnancy seemed to be associated with three groups of interconnected issues: subjective and individual issues (such as expectations, motivations, and women's difficulty in identifying their own consumption as risky); sociocultural and environmental issues (such as alcohol cultural value, easy access, and influence from relatives, friends, and partners); misinformation, inconsistent opinions publicized through media and lack of technically addressing the subject during prenatal care. Collective and individual health educative actions seem necessary to decrease alcohol consumption among Brazilian women with similar sociocultural characteristics. Media campaigns and explicit information about negative alcohol effects, articulated with individualized actions, such as a systematic approach of this theme during prenatal care, could allow earlier and more appropriate identification and intervention of women at risk.

Abstract
Objective This study aimed to look for a possible relationship between thyrotropin (TSH) values from neonatal bloodspot screening testing and newborn lower auditory pathway myelinization evaluated using the brainstem evoked response audiometry (ABR) test. Methods Sixty-two healthy full-term newborns without perinatal problems were enrolled in the study. TSH results were collected from neonatal bloodspot screening data and were below the test cut-off level (15μUI/mL). The TSH test was performed between three and seven days, and the ABR test was performed in the first 28 days of life. The newborns were divided into two groups: Group 1 (n = 35), TSH between 0 and 5μUI/mL, and group 2 (n = 27), TSH between 5 and 15μUI/mL. Data are presented as mean ± SD, median, or percentage, depending on the variable. Results Wave latency and interpeak interval values for Groups 1 and 2 were as follows: Wave I: 1.8 ± 0.1 and 1.7 ± 0.1; Wave III: 4.4 ± 0.1 and 4.4 ± 0.1; Wave V: 6.9 ± 0.1 and 6.9 ± 0.1; interval I–III: 2.6 ± 0.1 and 2.6 ± 0.1; interval I–V: 5.1 ± 0.1 and 5.1 ± 0.1; interval III–V: 2.4 ± 0.1 and 2.4 ± 0.1. There were no significant differences in ABR parameters between groups 1 and 2 (p > 0.05). Multiple regression analysis showed a slight significant negative correlation between TSH and wave I values (standardized β = −0.267; p = 0.036), without observing any relationship with the other ABR waves recorded. Conclusions This study investigated the relationship of TSH and auditory myelinization evaluated by ABR. It did not show a significant change in lower auditory pathway myelinization according to TSH levels in newborns with TSH screening levels lower than 15 μUI/mL.

Abstract
Problema: Embora individualmente raras, somadas, as doenças genéticas têm prevalência global estimada de 31,5 a 73,0 por 1.000 indivíduos. Além disto, doenças genéticas e defeitos congênitos representam a segunda causa de mortalidade infantil no Brasil. Diante deste cenário, foi instituída a Política Nacional de Atenção Integral às Pessoas com Doenças Raras no Sistema Único de Saúde. Esta política prevê funções específicas para Atenção Primária à Saúde (APS) que incluem diagnóstico precoce e mapeamento de pessoas com ou sob-risco de desenvolver doenças genéticas raras e/ou defeitos congênitos para encaminhamento regulado. Essa experiência objetivou colaborar com o desenvolvimento de métodos para o reconhecimento de indivíduos com ou sob-risco de desenvolver doenças genéticas na APS. Métodos: Através de visitas domiciliares e por meio do preenchimento de uma ficha específica, realizou-se busca ativa de casos de doença genética e/ou defeito congênito em uma amostra probabilística aleatória, representativa de uma Unidade de Saúde da Família de um município brasileiro de porte médio. Resultados: Foram investigados 295 domicílios, totalizando 1.160 indivíduos e 238 casais. A média de filhos por casal foi de 2,7, a frequência de consanguinidade foi 3,8% e de abortamento espontâneo foi 8,7%. Foram identificadas 29 pessoas (2,5%) com doenças congênitas, 11 (0,9%) com deficiências auditivas, 10 (0,9%) com deficiência mental e 6 (0,5%) com déficits visuais importantes. Atraso no desenvolvimento neuropsicomotor foi relatado em 8,8% das crianças e adolescentes. Doze indivíduos (1%) possuíam câncer e 9,6% relataram história familiar positiva para câncer. Conclusão: Os profissionais da APS estão em posição privilegiada para identificar e organizar uma rede de cuidados para indivíduos com doenças genéticas e/ou defeitos congênitos. A utilização sistemática de instrumentos que facilitem o reconhecimento de fatores de risco e de situações suspeitas pode ser uma estratégia útil a ser incorporada pela APS.

Abstract
OBJECTIVE This study analyzed the relationship between latent iron deficiency evaluated by ferritin, and the myelination of the central nervous system evaluated through the brainstem evoked response audiometry test. METHOD A total of 109 full-term newborns, born without anemia and risk factor for hearing deficiency, were enrolled. After delivery, umbilical cord blood was collected to determine ferritin and hematocrit levels. The brainstem evoked response audiometry test was carried out in the first 28 days of life. Analysis was performed between the control group (n=71) with ferritin greater than 75ng/mL, and the latent iron deficiency group (n=38) with ferritin between 11 and 75ng/mL. Results were presented as mean±standard deviation. Statistical analysis was performed using GraphPad prism7 and SPSS with a significance level of 5%. RESULTS A significant higher V-wave (p=0.02) and interpeak intervals I-III (p=0.014), I-V (p=0.0003), and III-V (p=0.0002) latencies were found in the latent iron deficiency group, as well as a significant inversely proportional correlation between ferritin and the same wave and intervals (p=0.003, p=0.0013, p=0.0002, p=0.009, respectively). Multiple correlation analysis showed a significant correlation of latent iron deficiency with all interpeak intervals, even taking into account newborn gestational age. CONCLUSION Iron deficiency anemia is a prevalent pathology; this study showed auditory delayed maturation associated to intrauterine iron deficiency, even in its latent form. This reinforces the importance of adopting effective measures, on a global scale, to prevent and treat this pathology in different life periods, especially in the most vulnerable population.

Abstract
RESUMO Objetivo Investigar a qualidade de vida familiar (QVF) entre famílias brasileiras que têm filhos com deficiência intelectual (DI) moderada. Métodos Estudo transversal, realizado com 50 famílias com filhos com DI moderada de São Carlos, São Paulo, Brasil. Os dados foram coletados por meio de formulários, com informações sociodemográficas, os índices de funcionalidade de Barthel e de Lawton & Brody e a Escala de Qualidade de Vida Familiar do Beach Center. Resultados Os domínios mais fortemente correlacionados com a QVF total foram “interação familiar” (r = 0,870; p < 0,001) e “cuidado dos pais com os filhos” (r = 0,845; p < 0,001). Não houve diferenças na distribuição da QVF em relação às variáveis sociodemográficas investigadas. Observou-se correlação moderada (r = 0,326) e significativa (p = 0,021) entre o índice de funcionalidade de Lawton & Brody e a QVF. O modelo de regressão linear ajustado explicou 10,6% da variabilidade encontrada na QVF (p = 0,021) e mostrou que o aumento de uma unidade no valor do índice de Lawton & Brody representou aumento de 0,092 na QVF. Conclusão A QVF das famílias investigadas encontra-se aquém de outras amostras internacionais. Ações clínicas que fortaleçam o diálogo e a coesão familiar e a construção de um plano terapêutico individualizado podem ser meios efetivos de ajuda a essas famílias.

Abstract
This qualitative clinical study investigated the impact of moderate intellectual disability on family dynamics and quality of life. The data were collected using individual interviews with 15 mothers of children with intellectual disabilities, as a convenience sample, and examined with categorical thematic content analysis. The results were discussed using a comprehensive and interpretative approach. Analysis of the interviews showed that care for children with intellectual disabilities is centered on the mother, contributing to the change in family relations. Religious coping appeared as a common strategy for adjusting. Children with intellectual disabilities had less access to services and support than they needed in the areas of health, education, and leisure. Financial constraints and difficulties in community living had a negative impact on the quality of family life. Emotional and psychological support for all the family members, and practical and social support, including income distribution and access to adequate services, proved essential for the well-being of children with intellectual disabilities and their families.

Abstract
Abstract Objectives: to investigate the prevalence of alcohol consumption during pregnancy and its sociodemographic, reproductive and newborn-related factors. Methods: a cross-sectional and exploratory study carried out on a sample of post-partum women, recruited daily over six months. Sociodemographic and reproductive information about the women and data concerning the newborns were collected. T-ACE questionnaire was used to identify the pattern of alcohol consumption by the women. They were divided into two groups: alcohol consumers (T-ACE score ≥2) and non-alcohol consumers. Comparisons between the two groups were made using the unpaired t test, chi-square test or Fisher's exact test according to the type of variable analyzed. The significance level was set at 5%. Results: out of 925 women, 818 (88.4%) agreed to participate. Among them, 60 (7.3%) were T-ACE positive, i.e. identified as alcohol consumers. Regarding the sociodemographic information, alcohol consumption was more frequent among women who did not have a steady partner (p=0.010). No reproductive variable presented a significant difference between the groups. A lower weight was observed among children of T-ACE positive mothers (3,045g±71.0 vs 3,192g±19.2; p=0.040). Conclusions: identifying and characterizing women who are more susceptible to alcohol consumption during pregnancy can contribute to developing more effective public health intervention strategies.

Abstract
Este ensaio teórico reflete sobre a qualificação e o provimento de médicos no contexto da Política Nacional de Atenção Integral às Pessoas com Doenças Raras no SUS. Para isso, apresentamos a Política e suas diretrizes, e situamos a discussão em torno de duas estratégias integradas: o provimento e a fixação de médicos geneticistas; e a capacitação de profissionais da Atenção Primária à Saúde em relação às doenças genéticas e aos defeitos congênitos. Finalmente, considerando as Diretrizes Curriculares Nacionais do Curso de Graduação em Medicina, apresentamos uma proposta de perfil de competência mínimo em Genética, elaborada para instrumentalizar os cursos de graduação da área da Saúde, em particular os cursos de Medicina. Assim, oferecemos um referencial teórico para apoiar o delineamento de programas de educação e formação em Saúde, contribuindo para inclusão do cuidado em Genética no SUS.

Abstract
Resumo Objetivou-se uma abordagem qualitativa de fatores que determinariam a qualidade de vida de pacientes com carcinoma papilífero de tireoide tratados. Foram feitas 16 entrevistas em profundidade com indivíduos de 18 a 45 anos sobre suas representações e experiências com esta enfermidade, seguidas por análise de conteúdo de enunciados. Os resultados contêm aspectos já previstos em questionários estruturados sobre qualidade de vida, mas outros estão parcialmente presumidos nesses questionários (manejo do conceito de etiologia da doença, a inserção “forçada” dos pacientes no universo conceitual médico, o medo do prognóstico e as mudanças “positivas” no estilo de vida). A interpretação desses resultados beneficiou-se de elaborações teóricas de desenvolvimento recente: as angústias sobre a experiência da doença parecem configurar-se, para os participantes, como um “risco moderno”, no contexto de uma “sociedade de riscos”. O desenvolvimento de questionários estruturados de qualidade de vida requer constantes estudos qualitativos que captem mudanças nos aspectos subjetivos do construto, dada a dinamicidade dos significados histórico-culturais e psicológicos do processo saúde-doença, constantemente influenciados por inovações tecnológicas e sucessivas interpretações epidemiológicas.

Abstract
Objetivo: Avaliar quais parâmetros os médicos da atenção primária à saúde do município de São Carlos, SP, Brasil, adotam para realizar triagem de função tireoidiana em crianças e adolescentes, quais exames complementares são solicitados e qual a conduta diante de resultados laboratoriais alterados. Métodos: Estudo transversal descritivo, no qual participaram 26 profissionais, correspondendo a 96,3% de todos os médicos da atenção primária da cidade que atuam no cuidado de crianças e adolescentes. Os participantes responderam por escrito quais as três situações mais frequentes na prática clínica em que indicavam triagem de hipotireoidismo na população pediátrica, quais os exames laboratoriais solicitados nesta avaliação e a qual conduta frente a exames com resultados alterados. Resultados: As situações clínicas mais frequentes apontadas pelos participantes como indicações de avaliação tireoidiana foram: obesidade, com 23 respostas (88,5%); baixa estatura, com 16 (61,5%); e síndrome de Down, com 8 (30,8%). Nove médicos (34,6%) responderam realizar o rastreio pela dosagem de TSH e T4l e outros 9 (34,6%), pela dosagem de TSH isolado. A conduta mais frequente diante de um resultado alterado foi o encaminhamento ao endocrinologista pediátrico, com 14 respostas (53,8%). Conclusão: O cenário encontrado neste estudo mostra que exames de função tireoidiana são solicitados rotineiramente por médicos da atenção primária no acompanhamento de crianças obesas. Como a obesidade infantil tem uma alta prevalência, isso pode determinar aumento importante dos custos do serviço de saúde e sobrecarga nos serviços de atenção especializada.

Abstract
As discoveries regarding the genetic contribution to disease have grown rapidly, health care professionals are expected to incorporate genetic and genomic perspectives into health education and practice. Genetic competencies common to all health professionals have been identified by the US National Coalition for Health Professional Education in Genetics (NCHPEG), which defined the knowledge, skills, and attitudes required to achieve these competencies. The aim of this study is to analyze genetic competencies of primary health care professionals in Brazil. It is a descriptive survey study, whereby doctors, nurses, and dentists were invited to participate by answering a questionnaire including 11 issues based on competencies established by the NCHPEG. Data were presented as percentages. Differences between groups of participants were assessed by the Fisher exact test, with the level of significance set at p < 0.05. Results showed that concerning knowledge, about 80 % of the participants recognized basic genetics terminology, but practitioners had difficulty in identifying patterns of inheritance. Regarding clinical skills, practitioners were able to recognize facial dysmorphias and identify situations where referral of patients to specialists was necessary. Nevertheless, there were challenges in the process of valuing and gathering information about family history. Regarding attitudes, 68.9 % of the participants thought about the comprehensiveness of care but faced challenges in counselling parents. The results of this study may contribute to developing an ongoing education program for primary health care professionals, leading to a strategy to overcome the challenges of including genetics in the Brazilian Unified Health System.

Abstract
We aimed to investigate 3,5,3′-triiodothyroacetic acid (TRIAC) effects on intact and atrophic skin induced by glucocorticoids (GCs) in rats and the effects induced by nanoencapsulation. The effects of TRIAC and nanoencapsulated TRIAC were evaluated on intact and atrophic skin in TRIAC experiment and nanoencapsulated TRIAC experiment, respectively. Both experiments had two phases: phase I, cutaneous atrophy was induced; phase II, TRIAC or nanoencapsulated TRIAC was administrated. Our results showed that topical use of TRIAC with or without nanoencapsulation was able to reverse cutaneous atrophy. Nanoencapsulated TRIAC showed less systemic changes than TRIAC; therefore, it is possibly a safer drug for topical administration.

Abstract
Topical glucocorticoid (GC) therapy has been successfully used in the treatment of several common cutaneous diseases in clinical practice for a long time, and skin atrophy is one of the most typical cutaneous side effects of this therapy. The aim of this study was to evaluate the potential of noninvasive fluorescence spectroscopy (FS) technique in the detection and classification of GC-induced skin atrophy. A total of 20 male Wistar rats were used in the experimental protocol under controlled environmental conditions and with free access to food. One group received topical application of clobetasol propionate 0.05% for 14 days to induce cutaneous atrophy (atrophic group) and the other (control) group received only vehicle application following the same protocol and schedule. Histological analyses and FS measurements with laser excitation at both 532 nm and 408 nm were obtained on days 1 and 15. The FS results were classified as "normal" or "atrophic" according by histological analysis. Fluorescence spectra obtained with excitation at 408 nm allowed a clear distinction between the control and atrophic groups, and were more informative than the those obtained at 532 nm. Our results reveal that, if correctly applied, FS allows noninvasive evaluation of corticosteroid-induced skin atrophy, and thus represents an important step towards better monitoring of undesirable side effects of cutaneous therapy.

Abstract
Objetivou-se relatar e discutir as experiências de um grupo de professores e alunos de graduação de Medicina sobre os estágios de iniciação científica, realizados por meio de projetos de pesquisa com métodos qualitativos, parte deles tendo a Atenção Primária à Saúde como campo de pesquisa. Contextualizando o relato, acentuou-se a história relativamente recente da iniciação científica no Brasil e, em nível mundial, a também recente utilização em mais ampla escala dos métodos qualitativos em saúde. O relato de experiência se estruturou a partir do fluxograma do processo de trabalho seguido pelos estágios de iniciação científica. Destacou-se ter havido uma relativa autonomia dos estudantes em relação à coleta de dados, mas, por outro lado, maior dependência em relação aos seus orientadores no momento de analisar e interpretar os achados. Por meio desses estágios, acredita-se que se valoriza a rede de significados presentes no processo saúde-doença-cuidado, em particular na Atenção Primária à Saúde, considerando que uma progressiva compreensão científica desse processo complexo ajuda a aperfeiçoar uma prática médica atenta às plenas necessidades de pacientes e comunidades.

Abstract
Melanocortin system and corticotropin releasing hormone (CRH) are implicated in the control of feeding behavior. Besides its anorexigenic effect on food intake, CRH is one of the most important regulators of hypothalamic-pituitary-adrenal (HPA) axis activity. Therefore, there could be an interplay between HPA axis activity and melanocortin system. We investigated the expression of melanocortin-4 receptor (MC4-R) mRNA in the hypothalamus of rats after 14 days of food restriction or after a fasting-refeeding regimen, in sham or adrenalectomized rats. Male Wistar rats were subjected to free access to food or food ingestion restricted for 2 h a day (8-10 AM) during 14 d, when plasma corticosterone, ACTH, insulin, leptin concentrations, and MC4-R mRNA expression were determined before and after refeeding. Another set of rats was fasted for 48 h, followed by refeeding during 2 or 4 h on the seventh day after adrenalectomy (ADX) or sham surgery. On the day of the experiment, rats were anesthetized and perfused and the brain processed for MC4-R mRNA by in situ hybridization. Long-term reduction of food intake, either secondary to food restriction or adrenalectomy, reduced body weight gain and also leptin and insulin plasma concentrations. Food ingestion reduced MC4-R expression in the paraventricular nucleus in naive rats subjected to food restriction and also in sham rats fasted for 48 h. However, after ADX, MC4-R expression was not changed by refeeding. In conclusion, the present data indicate that MC4-R expression is downregulated by food ingestion and this response could be modulated by glucocorticoid withdrawal.

Abstract
Inflammatory and infectious processes evoke neuroendocrine and behavioral changes known as acute-phase response that includes activation of the hypothalamo-pituitary-adrenal (HPA) axis and reduction of food intake. Besides its action as the most important ACTH secretagogue, corticotrophin-releasing factor (CRF), synthesized in the paraventricular nucleus (PVN), is also involved in the control of food intake. Alpha-melanocyte stimulating hormone (alpha-MSH) in the arcuate nucleus also plays a role in the energy homeostasis, possessing anorexigenic effects. To investigate the participation of neuropeptides involved in the regulation of food intake during endotoxemia, we administrated lipopolysaccharide (LPS) in sham-operated and adrenalectomized (ADX) male Wistar rats to evaluate food intake, hormone responses and Fos-CRF and Fos-alpha-MSH immunoreactivity in the PVN and arcuate nucleus, as well as CRF and POMC mRNA expression in these hypothalamic nuclei. In sham-operated rats, treatment with LPS (100 microg/kg) showed lower food intake, higher plasma ACTH and corticosterone levels, as well as an increase in Fos-CRF double labeled neurons and CRF mRNA expression in the PVN, with no changes in Fos-alpha-MSH immunoreactivity and POMC mRNA expression in the arcuate nucleus, compared to saline treated rats. After LPS treatment, ADX rats showed further increase in plasma ACTH levels, marked decrease of food intake, higher Fos-CRF immunoreactive neurons in the PVN and CRF mRNA expression, as well as an increase in Fos-alpha-MSH immunoreactivity and POMC mRNA expression in the arcuate nucleus, compared to sham-operated rats treated with LPS. In conclusion, the present data indicate that the marked hypophagia during endotoxemia following ADX is associated with an increased activation of CRF and POMC neurons in the hypothalamus and an increased mRNA expression of these neuropeptides.

Abstract
This study evaluated the responses of vasopressin (AVP) and oxytocin (OT) neurons to alterations in hypothalamo-pituitary axis activity by adrenalectomy (ADX) or after restraint stress compared with basal conditions. Wistar male rats were perfuse-fixed by cardiac perfusion under anesthesia 3 h, 1, 3 and 14 days after ADX or Sham surgery. Coronal hypothalamic sections were used for evaluation of Fos, AVP and OT expression by immunohistochemistry. Under basal conditions and after stress, Fos-AVP double labeling showed no difference in the magnocellular subdivisions of the paraventricular nuclei (PVN) or in the supraoptic nuclei (SON), suggesting that the magnocellular AVP system is unlikely to contribute to ACTH secretion after restraint in both Sham and ADX rats. Fos-AVP double labeling in the parvocellular medial paraventricular nucleus (PaMP) in ADX groups was increased after 3 h in basal conditions, and in all periods after restraint stress. There were no differences between Sham and ADX groups in Fos-OT double labeling in any subdivision of the PVN; however, in the SON, the number of Fos-OT double labeled cells was increased at all time-points after stress in the ADX group. Fos expression was increased in the PaMP after 3 h and after restraint stress in the Sham and ADX groups, especially in the ADX group. In conclusion, Fos expression in different cell populations of the PVN can be differentially regulated by short- and long-term absence of glucocorticoid negative feedback and also by stress-related excitatory and/or inhibitory neural inputs. The Fos-AVP double labeling findings in the PaMP also indicate a minor participation of these vasopressinergic neurons in the regulation of the HPA axis after ADX.

Abstract
Plasma renin activity (PRA) determination is the main index used to evaluate the mineralocorticoid control in 21-hydroxylase deficiency (21-OHD). PRA values within or at the upper limit of the age-appropriate range, or values <5 or 10 ng/ml/h have been regarded as adequate control. Atrial natriuretic peptide (ANP) has opposite actions to those of angiotensin II/aldosterone, and could help to understand the hydrosaline homeostasis in 21-OHD. We studied the interaction between PRA and ANP levels in 10 controls and 26 patients with 21-OHD under corticoid treatment. Patients were divided into two groups according to PRA levels, < or > or = 5 ng/ml/h, irrespective of the clinical form of 21-OHD. Blood samples for determination of PRA and ANP levels were taken after 30 min in the sitting position (basal), after 30 min in the recumbent position and after 15 min of 20 degrees head-down tilting. ANP levels (pg/ml) in the basal, supine and after head-down tilting position were 25.9 +/- 1.6, 42.7 +/- 7.4 and 54.3 +/- 5.5 in controls; 28.5 +/- 2.1, 38.3 +/- 2.1 and 48.8 +/- 4.1 in the group with PRA levels <5 ng/ml/h, and 20.9 +/- 1.9, 26.6 +/- 2.5 and 34.6 +/- 3.1 in the group with PRA levels > or = 5 ng/ml/h, respectively. Basal and after head-down tilting ANP plasma levels were similar between the controls and the group with PRA levels <5 ng/ml/h. However, the group of patients with PRA levels > or = 5 ng/ml/h showed lower basal and stimulated ANP levels compared to the control group (p<0.05). The decreased plasma ANP levels in the basal condition and after head-down tilting indicate a chronic contraction of the extracellular volume in 21-OHD patients with increased PRA levels. Therefore, mineralocorticoid deficiency is counteracted by decreased ANP secretion in order to preserve fluid and electrolyte homeostasis.

Abstract
Deficiency of 21-hydroxylase is the most common form of congenital adrenal hyperplasia (CAH-21OH). We determined by allele-specific PCR the frequency of microconversion in the CYP21A2 gene in 50 Brazilian patients with the classical (salt wasting: SW and simple virilizing: SV) forms and nonclassical (NC) form of CAH-21OH and correlated genotype with phenotype. Genotypes were classified into three mutation groups (A, B, and C) based on the amount of enzymatic activity in in vitro studies using adrenal cells. In 94 unrelated alleles, we diagnosed 76% of the affected alleles after screening for 7 microconversions. The most frequent point mutations observed in this series were I172N (19%), V281L (18%), and IVS2,A/C>G,-12 (15%). In the SW form, the most frequent mutation was IVS2,A/C>G,-12 (38%), in the SV form it was I172N (53%), and in the NC form it was V281L (57.7%). We observed a good correlation between genotype and phenotype. Discordance between genotype and phenotype was found in one SV patient with a mild mutation in one of the alleles (R356W/V281L). However, we cannot rule out the presence of an additional mutation in these alleles. We also observed a good correlation of genotype with 17alpha-hydroxyprogesterone, testosterone, and androstenedione levels. The severity of external genitalia virilization correlated with the severity of mutation. In conclusion, the frequencies described in the present study did not differ from worldwide studies, including the Brazilian population. The few differences observed may reflect individual sample variations. This new Brazilian cohort study suggests the presence of new mutations in Brazilian patients with different forms of CAH-21OH.
