CONTEXT AND OBJECTIVE: The relationship between sex hormones and asthma has been evaluated in several studies. The aim of this review article was to investigate the association between asthma and female sex hormones, under different conditions (premenstrual asthma, use of oral contraceptives, menopause, hormone replacement therapy and pregnancy). DESIGN AND SETTING: Narrative review of the medical literature, Universidade Federal do Tocantins (UFT) and Universidade Federal de São Paulo (Unifesp). METHODS:We searched the CAPES journal portal, a Brazilian platform that provides access to articles in the MEDLINE, PubMed, SciELO, and LILACS databases. The following keywords were used based on Medical Subject Headings: asthma, sex hormones, women and use of oral contraceptives. RESULTS:The associations between sex hormones and asthma remain obscure. In adults, asthma is more common in women than in men. In addition, mortality due to asthma is significantly higher among females. The immune system is influenced by sex hormones: either because progesterone stimulates progesterone-induced blocking factor and Th2 cytokines or because contraceptives derived from progesterone and estrogen stimulate the transcription factor GATA-3. CONCLUSIONS:The associations between asthma and female sex hormones remain obscure. We speculate that estrogen fluctuations are responsible for asthma exacerbations that occur in women. Because of the anti-inflammatory action of estrogen, it decreases TNF-α production, interferon-γ expression and NK cell activity. We suggest that further studies that highlight the underlying physiopathological mechanisms contributing towards these interactions should be conducted. RESUMO CONTEXTO E OBJETIVO:A relação entre os hormônios sexuais e a asma tem sido investigada em diversos estudos. Esta revisão tem como objetivo descrever a relação entre hormônios sexuais (endógenos e exó-genos) e a inflamação nas vias aéreas, especialmente na asma, em eventos diferentes (na asma pré-menstrual, durante o uso de anticoncepcionais, na menopausa, no uso de terapia hormonal e na gestação). TIPO DE ESTUDO E LOCAL:Revisão narrativa da literatura médica, Universidade Federal do Tocantins (UFT) e Universidade Federal de São Paulo (Unifesp). MÉTODO: Pesquisamos o Portal de Periódicos Capes, uma plataforma brasileira que fornece acesso a artigos nas bases de dados MEDLINE, PubMed, SciELO e LILACS. Os descritores utilizados foram asma, hormônios sexuais, mulheres e uso de anticoncepcionais, com base no "Medical Subject Headings". RESULTADOS: As associações entre hormônios sexuais e asma ainda permanecem obscuras. Em adultos, a asma é mais frequente em mulheres do que em homens. Além disso, a mortalidade por asma é significativamente maior no sexo feminino, destacando-se que o sistema imunológico sofre influência de hormônios sexuais, seja porque a progesterona estimula o fator bloqueador induzido pela progesterona e citocinas Th2 ou porque contraceptivos derivados de progesterona e estrógeno estimulam o fator de transcriç...

CONTEXT AND OBJECTIVE: Few studies have assessed the impact of medical residencies on the public healthcare system. The aim here was to assess the number of specialists who remained in the state of Tocantins after finishing the medical residency program during the first two years of the first programs (2013 and 2014). DESIGN AND SETTING: Cross-sectional and exploratory study conducted at the Federal University of Tocantins in Brazil. METHODS: All graduates of medical residency programs in Tocantins, of the years 2013 and 2014, were interviewed by telephone and e-mail between May and July 2014. RESULTS: Information was obtained from 37 graduates from medical residency. Seventeen (50.0%) were working in the state public healthcare system and only six (17.6%) in a municipal service in June 2014. Considering only the 24 doctors who had never worked in the state of Tocantins before their residency, it was observed that two who graduated in 2013 (20.0%) and five who graduated in 2014 (35.7%), i.e. seven out of the total number (29.2%), had established their homes in Tocantins. CONCLUSIONS: The number of graduates from medical residency who stayed in the state of Tocantins in 2013 and 2014 was small. However, this was related to the absence of other programs for continuation of the specialization. The state healthcare system was primarily responsible for employment of these doctors within public services. On the other hand, hiring by municipal services was extremely low.

CONTEXT AND OBJECTIVE: Knowledge of the profile of allergen sensitization among children is important for planning preventive measures. The objective of this study was to assess the prevalence and profile of sensitization to inhaled allergens and food among children and adolescents in an outpatient population in the city of Palmas. DESIGN AND SETTING: Cross-sectional study at outpatient clinics in Palmas, Tocantins, Brazil. METHODS: Ninety-four patients aged 1-15 years who were attending two pediatric outpatient clinics were selected between September and November 2008. All of the subjects underwent clinical interviews and skin prick tests. RESULTS:A positive skin prick test was observed in 76.6% of the participants (72.3% for inhalants and 28.9% for food allergens). The most frequent allergens were Dermatophagoides pteronyssinus (34%), cat epithelium (28.7%), dog epithelium (21.3%), Dermatophagoides farinae (19.1%), Blomia tropicalis (18.1%), cow's milk (9.6%) and grasses (9.6%). A positive skin prick test correlated with a history of atopic disease (odds ratio, OR = 5.833; P = 0.002), a family history of atopic disease (OR = 8.400; P < 0.001), maternal asthma (OR = 8.077; P = 0.048), pet exposure (OR = 3.600; P = 0.012) and cesarean delivery (OR = 3.367; P = 0.019). CONCLUSION: Dermatophagoides pteronyssinus was the most frequent aeroallergen and cow's milk was the most prevalent food allergen. There was a positive correlation between a positive skin prick test and several factors, such as a family history of atopic disease, maternal asthma, pet exposure and cesarean delivery.RESUMO CONTEXTO E OBJETIVO: O conhecimento sobre o perfil da sensibilização a alérgenos em crianças é importante para o planejamento de medidas preventivas. O objetivo deste estudo foi avaliar a prevalência e perfil de sensibilização a alérgenos inalados e alimentares em crianças e adolescentes em uma população ambulatorial na cidade de Palmas. TIPO DE ESTUDO E LOCAL: Estudo transversal em unidades ambulatoriais em Palmas, Tocantins, Brasil. MÉTODOS: Foram selecionados 94 pacientes com idades entre 1 a 15 anos em 2 ambulatórios de pediatria entre setembro e novembro de 2008. Todos os sujeitos foram submetidos a entrevistas clínicas e testes cutâneos de puntura. RESULTADOS: Um teste cutâneo de puntura positivo foi observado em 76,6% dos participantes (72,3% para inalantes, 28,9% para alérgenos alimentares). Os alérgenos mais frequentes foram Dermatophagoides pteronyssinus (34%), epitélio de gato (28,7%), epitélio de cão (21,3%), Dermatophagoides farinae (19,1%), Blomia tropicalis (18,1%), leite de vaca (9,6%) e gramíneas (9,6%). Um teste cutâneo de puntura positivo foi relacionado à história de doença atópica (razão de chances RC = 5,833, P = 0,002), história familiar de atopia (RC = 8,400, P < 0,001), asma materna (RC = 8,077, P = 0,048), exposição a animal de estimação (RC = 3,600, P = 0,012) e parto cesáreo (RC = 3,367, P = 0,019). CONCLUSÃO: Dermatophagoides pteronyssinus foi o aeroalérgeno mais prevalente e, dentre alérgenos a...

Introduction: The accomplishment of medical residency (MR) is a type of qualification considered to be the “gold standard” for medical specialization. Understanding whether there is actually greater professional settlement or not stimulated by MR and which factors hinder or contribute to the physician’s permanence in that place, are important information for the structuring of medical residency and health system programs. The aim of this study was to evaluate the prevalence of settlement of medical residents who finished the residency training in the state of Tocantins, after the implementation of medical residency programs in the period from 2013 to 2017. Method: This is an observational quantitative research, with a cross-sectional, descriptive and analytical design, using the telematic technique and its own questionnaire, carried out with 44 medical residents that finished the medical residency program in the state of Tocantins. The project was reviewed and approved by the Ethics Committee of the Federal University of Tocantins (UFT) under Opinion number 2.292.540. Results: The prevalence of settlement was 65.9% of physicians in the state of Tocantins. Most residents were females (59.1%), with a mean age of 30.8 ± 3.1 years, income between 10 and 20 minimum wages (55.8%) and worked during their residency training (84.1%). The specialties that showed the highest settlement rates were general surgery and clinical medicine, and among these, the majority works for the private and state health networks. The main reason for not settling in Tocantins was to attend another residency or subspecialty program in another state (64.7%). Conclusion: The prevalence of medical residents that finished the residency and settled in Tocantins during the analyzed period can be considered high (65.9%). The fact that most of these individuals are young and female and the reason for not settling in the state are important indicators to be analyzed together with the settlement process and the offering of positions in the specialties available in Tocantins. The results of the study indicated a favorable and strategic perspective of the Medical Residency Programs (MRP) in the medical settlement in Tocantins, which cannot be generalized to the reality of such an unequal health system in the country. A larger public investment in the structuring of health network services is necessary, especially in the municipal network, in the organization of support and socioeconomic development of cities.

tryptase (sBT) levels on day 3 and 4 were found at 25.6 mg/L and 24.2 mg/L respectively, suggestive of an unknown indolent systemic mastocytosis (ISM). Specific IgE were positive for the 2 wasp venoms, but not for honeybee venom.

ObjectiveTo assess the impact of COVID-19 second wave on quality of life (QoL) of Brazilian medical students.MethodsThe data from 210 medical students were collected through a web-based survey between February and March 2021. We assessed information about sociodemographic characteristics, health conditions, electronics tools-related to physical activity (PA-eTool), and health-associated QoL. Multiple linear regression was performed to identify the potential QoL predictors.ResultsThe psychological domain was the most affected, showing lower score during COVID-19 second wave. Being male was a positive predictor in the physical health domain. Spending too much time indoors and sexual minority-group membership were associated with lower perception on psychological well-being. Personal benefit from having PA-eTool accessed and higher income were positively associated with psychological and environmental domains, respectively, and in the overall QoL.ConclusionsPsychological well-being impairment is a long-term negative impact among Brazilian medical students during COVID-19. By evidencing that students’ QoL has been worsened in this global crisis, supportive interventions provided by community and universities are required to aid those vulnerable students facing mental health or QoL impairment.
