Common mental disorders and socioeconomic status in adolescents of ERICA.

INTRODUCTION: Adolescence is a stage of great social, family and emotional demands, and the literature has related common mental disorder (CMD) with poor living conditions. OBJECTIVE: To investigate the relationship between CMD and socioeconomic status in Brazilian adolescents aged 12 to 17 years. METHOD: This is a cross-sectional study with data from the Study of Cardiovascular Risk in Adolescents (ERICA - Estudo de Riscos Cardiovasculares em Adolescentes). The outcome was CMD and the exposure was socioeconomic status assessed by race/skin color, maternal schooling, resident/room relationship, type of school, existence of maid and bathroom at home, and work activity. For the calculation of prevalence, the survey mode was used and, in the multivariate analysis, logistic regression with p < 5%, as well as the 95% confidence interval. RESULTS: The prevalence of CMD in girls was 23.3%, and in boys, 11.1%. The variables associated with CMD in girls were age between 15 and 17 years (OR = 1.34; 1.17-1.51), studying in private school (OR = 1.13; 1.01-1.27), having a housemaid (OR = 1.15; 1.00-1.34) and, as a protective factor, unpaid work (OR = 0.64; 0.55-0.75). Boys also had a higher chance of CMD in the highest age group (OR = 1.42; 1.18-1.71) and when they had a housemaid (OR = 1.26; 1.02-1.57), whereas unpaid work decreased this chance (OR = 0.79; 0.67-0.95). CONCLUSION: Socioeconomic variables that were associated with CMD were suggestive of higher economic class, whereas unpaid work favored the mental health of adolescents, results contrary to the literature on socioeconomic status and CMD.

RESUMO INTRODUÇÃO: A adolescência é uma fase de grande demanda social, familiar e emocional, e a literatura tem relacionado o transtorno mental comum (TMC) com piores condições de vida. OBJETIVO: Investigar a relação entre TMC e a condição socioeconômica em adolescentes brasileiros de 12 a 17 anos. MÉTODO: Estudo seccional com os dados do Estudo de Riscos Cardiovasculares em Adolescentes (Erica). O desfecho foi o TMC e a exposição foi a condição socioeconômica avaliada por raça/cor, escolaridade materna, relação morador/cômodo, tipo de escola, existência de empregada e banheiro no domicílio e atividade laboral. Para o cálculo das prevalências, foi utilizado o modo survey e, na análise multivariada, a regressão logística com p < 5%, assim como o intervalo de confiança de 95%. RESULTADOS: A prevalência de TMC em meninas foi 23,3% e em meninos, 11,1%. As variáveis associadas ao TMC nas meninas foram ter idade entre 15 e 17 anos (OR = 1,34; 1,17-1,51), estudar em escola privada (OR = 1,13; 1,01-1,27), ter empregada doméstica (OR = 1,15; 1,00-1,34) e, como fator de proteção, o trabalho não remunerado (OR = 0,64; 0,55-0,75). Os meninos também apresentaram maior chance de TMC na faixa etária mais alta (OR = 1,42; 1,18-1,71) e quando tinham empregada (OR = 1,26; 1,02-1,57), enquanto o trabalho não remunerado diminuiu essa chance (OR = 0,79; 0,67-0,95). CONCLUSÃO: As variáveis socioeconômicas que estiveram associadas ao TMC foram sugestivas de classe econômica mais elevada, enquanto o trabalho não remunerado favoreceu a saúde mental dos adolescentes, resultados contrários à literatura sobre condição socioeconômica e TMC.

Colic in equidae from Rio Grande do Norte: retrospective study of the main clinical and epidemiological findings in 25 cases / Cólica em equídeos no Rio Grande do Norte: estudo retrospectivo dos principais achados clínico-epidemiológicos de 25 casos

The present article aimed to conduct a retrospective study of the main clinical and epidemiological findings in 25 cases of colic in equidae from Rio Grande do Norte. Twenty five equidae (21 horses, three mules and one donkey) were included. Clinical treatment was performed in 15 equidae with moderate large colon impaction (n = 6), cecal bloat (n = 4), gastric overload (n = 3), cecal impaction (n = 1) and gastric ulcers (n = 1). Six horses with severe large colon impaction (n = 2), meconium impaction (n = 2), left dorsal displacement of the large colon (n = 1) and verminotic arteritis (n = 1) were submitted to exploratory laparotomy. Four horses were not treated due to severe systemic disturbances and poor prognosis. Higher incidence occurred in Quarter horses and crossbreed horses followed by mules and single cases in a pony and a donkey. Impactions of the large intestine and cecal bloat were the major causes of colic in equidae from this study; and mainly resulted from erroneous feeding management by the owners or handlers.(AU)

O presente artigo teve como objetivo realizar um estudo retrospectivo dos principais achados clínicos-epidemiológicos em 25 casos de cólica em equídeos do Rio Grande do Norte. Vinte e cinco equídeos (21 cavalos, três muares e um asinino) foram incluídos. O tratamento clínico foi realizado em 15 equídeos com compactação do cólon moderada (n = 6), timpanismo cecal (n = 4), sobrecarga gástrica (n = 3), compactação de ceco (n = 1) e úlceras gástricas (n = 1). Seis equinos com compactação do cólon grave (n = 2), retenção de mecônio (n = 2), deslocamento dorsal do cólon maior esquerdo (n = 1) e arterite verminótica (n = 1) foram submetidos à laparotomia exploratória. Quatro equinos não foram tratados devido aos distúrbios sistêmicos graves e prognóstico ruim. A maior incidência ocorreu em equinos Quarto de Milha e seus mestiços, seguidos por muares e casos únicos em um pônei e um asinino. Compactações do intestino grosso e o timpanismo cecal foram as principais causas de cólica em equídeos deste estudo, e, principalmente, como consequência do manejo alimentar errôneo por parte dos proprietários ou tratadores.(AU)

Detection of Theileria equi in spleen and blood of asymptomatic piroplasm carrier horses.

This study aimed to determine whether asymptomatic horses naturally infected with Theileria equi retain infected erythrocytes in the spleen and whether the presence of the hemoparasite in this organ is associated with parasitemia. We collected samples from 25 adult horses without clinical signs of any disease. From each animal, we collected whole blood samples from the jugular vein and a splenic puncture blood sample. All samples were submited to blood cell counts and detection of Theileria or Babesia. DNA extraction and PCR were performed in all samples for identification of piroplasm infection (T. equi and B. caballi). From the 25 horses evaluated for piroplasm detection by PCR, seven horses (28%) were positive in jugular vein blood but negative in splenic blood samples, five horses (20%) were positive in splenic blood samples but negative in jugular vein blood samples, and 13 horses (52%) were positive in both jugular vein and splenic blood samples. The hematological evaluation revealed anemia in 13 of 25 (52%) infected horses, lymphopenia in five (20%), neutrophilia in two (8%), neutropenia in one (4%), and thrombocytopenia in one (4%) infected horse. The present study demonstrated that several (20%) of the asymptomatic piroplasm carrier horses did not show parasitemia, but show infected erythrocytes in the spleen.

Anesthetic approach of pregnant woman with cerebral arteriovenous malformation and subarachnoid hemorrhage during pregnancy: case report.

BACKGROUND AND OBJECTIVES: Subarachnoid hemorrhage (SAH) during pregnancy is a rare event, and about half the cases are due to arteriovenous malformations (AVM). The authors describe the anesthetic approach of a 39 week pregnant patient scheduled for cesarean section, with a history of SAH due to AVM at 22 week gestation. CASE REPORT: 39 week pregnant patient, healthy prior to pregnancy, with a history of SAH at 22 week gestation, manifested by headache, vomiting, and dizziness without loss of consciousness or other deficits on admission to the emergency room. Magnetic resonance imaging (MRI) revealed a left frontal AVM. After a short hospital stay for stabilization and diagnosis, the fi nal medical decision was to maintain the pregnancy and a multidisciplinary follow-up by neurosurgery and high-risk obstetric consultation. An elective cesarean section was performed at 39 weeks under epidural anesthesia. During the intraoperative period, an episode of hypotension rapidly reversed with phenylephrine occurred. The newborn Apgar score was 10/10. An epidural catheter was used for postoperative analgesia, also uneventful. CONCLUSIONS: There are very few published cases of anesthetic approach for pregnant women with symptomatic AVM. All decisions made by the multidisciplinary team, from choosing to continue the pregnancy to the ideal time for AVM intervention and type of anesthesia and analgesia, were weighted according to the risk of brain damage. Regarding the anesthetic procedure, the authors emphasize the need for hemodynamic stability.

Abordagem anestésica de grávida com malformação arteriovenosa cerebral e hemorragia subaracnoidea durante a gravidez: relato de caso / Anesthetic approach of pregnant woman with cerebral arteriovenous malformation and subarachnoid hemorrhage during pregnancy: case report / Abordaje anestésico de embarazada con malformación arteriovenosa cerebral y hemorragia subaracnoidea durante el embarazo: relato de caso

JUSTIFICATIVA E OBJETIVOS: A ocorrência de hemorragia subaracnoidea (HSA) durante a gravidez é rara, sendo que cerca de metade é devida a malformações arteriovenosas (MAV). Os autores descrevem a abordagem anestésica de uma grávida de 39 semanas proposta para cesárea, com história de HSA por MAV às 22 semanas. RELATO DO CASO: Grávida de 39 semanas, saudável previamente à gravidez, com antecedentes de HSA às 22 semanas de gestação, manifestada por cefaleias, vômitos e tonturas, sem perda de consciência ou outros déficits à admissão no serviço de urgência. A ressonância magnética (RM) revelou MAV frontal esquerda. Após curto internamento para estabilização e diagnóstico, decidiu-se manter a gravidez e o seguimento ambulatorial multidisciplinar por neurocirurgia e obstetrícia em consulta de alto risco. Optou-se por fazer cesárea eletiva às 39 semanas sob anestesia peridural lombar. No intraoperatório ocorreu um episódio de hipotensão rapidamente revertida com fenilefrina. O Índice de Apgar do recém-nascido foi de 10/10. O cateter peridural foi usado para analgesia pós-operatória, também sem intercorrências. CONCLUSÕES: São muito raros os casos publicados de abordagem anestésica de grávidas com MAV sintomáticas. Todas as decisões tomadas pela equipe multidisciplinar, desde optar por continuar a gravidez ao momento ideal para intervir na MAV, passando pelo tipo de anestesia e analgesia, foram ponderadas em função do risco de dano cerebral. Do ponto de vista anestésico, os autores enfatizam a necessidade de estabilidade hemodinâmica.

Helix 12 dynamics and thyroid hormone receptor activity: experimental and molecular dynamics studies of Ile280 mutants.

Nuclear hormone receptors (NRs) form a family of transcription factors that mediate cellular responses initiated by hormone binding. It is generally recognized that the structure and dynamics of the C-terminal helix 12 (H12) of NRs' ligand binding domain (LBD) are fundamental to the recognition of coactivators and corepressors that modulate receptor function. Here we study the role of three mutations in the I280 residue of H12 of thyroid hormone receptors using site-directed mutagenesis, functional assays, and molecular dynamics simulations. Although residues at position 280 do not interact with coactivators or with the ligand, we show that its mutations can selectively block coactivator and corepressor binding, and affect hormone binding affinity differently. Molecular dynamics simulations suggest that ligand affinity is reduced by indirectly displacing the ligand in the binding pocket, facilitating water penetration and ligand destabilization. Mutations I280R and I280K link H12 to the LBD by forming salt bridges with E457 in H12, stabilizing H12 in a conformation that blocks both corepressor and coactivator recruitment. The I280M mutation, in turn, blocks corepressor binding, but appears to enhance coactivator affinity, suggesting stabilization of H12 in agonist conformation.

Myocardial infarction in the 31st week of pregnancy--case report.

BACKGROUND AND OBJECTIVES: The occurrence of acute myocardial infarction (AMI) during pregnancy is rare. The authors describe the case of MI in a 31-week pregnant woman and the importance of a multidisciplinary team for its approach. CASE REPORT: Thirty-one week pregnant woman with history of smoking, alcoholism and hypertension was admitted after an episode of syncope. On admission she was conscious and asymptomatic, although hypotensive. The electrocardiogram showed marked ST-segment elevation in D1, aVL, V1-V6. The cardiac enzymes were positive. The transthoracic echocardiogram showed reduction in septal and left ventricular contractility and an ejection fraction of 30%. Angiography revealed proximal occlusion of the left anterior descending artery. After a non-successful balloon angioplasty, a metallic stent was placed. The patient started therapy with beta-blockers, aspirin and clopidogrel. As for the delivery, we chose to perform a cesarean section four weeks after MI. Clopidogrel was suspended seven days before delivery. The preoperative cardiac function was improved by infusion of levosimendan started the day before. Cesarean section occurred under epidural block. The intraoperative period showed no complications, except for mild hypotension easily corrected with phenylephrine. The Apgar score for the newborn was 9/10. CONCLUSIONS: This is one of the few cases of myocardial infarction and angioplasty reported during pregnancy. The authors discuss the decisions taken by the multidisciplinary team consisting of anesthesiologists, obstetricians, neonatologists and cardiologists, particularly with regard to dual antiplatelet therapy, the type of delivery and anesthesia.

Infarto agudo do miocárdio na 31ª semana de gravidez: relato de caso / Myocardial infarction in the 31st week of pregnancy: case report

JUSTIFICATIVA E OBJETIVOS: A ocorrência de infarto agudo do miocárdio (IAM) durante a gravidez é rara. Os autores descrevem o caso de IAM numa grávida de 31 semanas e a importância da existência de uma equipe multidisciplinar para sua abordagem. RELATO DO CASO: Grávida de 31 semanas, com antecedentes de tabagismo, alcoolismo e hipertensão, internada após um episódio de síncope. Na admissão, encontrava-se consciente e assintomática, embora hipotensa. O eletrocardiograma evidenciou marcada elevação do segmento ST em DI, AVL, V1-V6. Pesquisa de enzimas cardíacas foi positiva. O ecocardiograma transtorácico demonstrou redução da contratilidade ventricular esquerda e septal e uma fração de ejeção de 30 por cento. A angiografia revelou oclusão proximal da artéria descendente anterior. Por insucesso da angioplastia por balão, foi colocado um stent metálico. A paciente iniciou terapêutica com b-bloqueadores, aspirina e clopidogrel. Em relação ao parto, optou-se por realizar cesariana eletiva, quatro semanas após o IAM. Suspendeu-se o clopidogrel sete dias antes do parto. A função cardíaca pré-operatória foi otimizada com infusão de levosimendana iniciada no dia anterior. A cesariana decorreu sob bloqueio peridural. O período intraoperatório decorreu sem complicações, à exceção de moderada hipotensão facilmente corrigida com fenilefrina. O índice de Apgar do recém-nascido foi de 9/10. CONCLUSÕES: Este é um dos poucos casos de infarto agudo do miocárdio e angioplastia descritos durante a gravidez. Os autores discutem as decisões tomadas pela equipe multidisciplinar, constituída por anestesiologistas, obstetras, cardiologistas e neonatologistas, notadamente no que se refere à dupla antiagregação plaquetária, ao tipo de parto e à anestesia.

HDL atheroprotection by aerobic exercise training in type 2 diabetes mellitus.

PURPOSE: In this study we analyzed the role played by aerobic exercise training in the plasma lipoprotein profile, prebeta 1-HDL concentration, and in the in vitro HDL3 ability to remove cholesterol from macrophages and inhibit LDL oxidation in type 2 diabetes mellitus (DM) patients and control subjects, in the fasting and postprandial states. METHODS: Healthy controls (HTC, N = 11; 1 M/10 F) and subjects with type 2 diabetes mellitus (DMT, N = 11; 3M/8F) were engaged in a 4-month aerobic training program, and compared with a group of sedentary subjects with type 2 diabetes mellitus (DMS, N = 10; 4 M/6 F). All groups were submitted to an oral fat load test to analyze all parameters, both at the beginning of the investigation protocol (basal) and at the end of the study period (final). RESULTS: Exercising did not modify body weight, BMI, plasma concentrations of total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides (TG), glucose, insulin, or HOMA-IR, but it reduced the waist circumference. The HDL3 composition did not change, and its ability to remove cell cholesterol was unaltered by aerobic training. In DMT but not in HTC, aerobic training improved 15% the HDL3 protective effect against LDL maximal oxidation rate in the fasting state, and reduced 24% the plasma prebeta 1-HDL concentration in the postprandial state, suggesting an enhanced prebeta 1-HDL conversion into larger, more mature HDL particles. In this regard, regular aerobic exercise enriched HDL2 with TG in the fasting and postprandial states in HTC and in the fasting phase in DMT. CONCLUSION: Our results show that aerobic exercise training in diabetes mellitus improves the HDL efficiency against LDL oxidation and favors HDL maturation. These findings were independent of changes in insulin resistance and of the rise of plasma HDL cholesterol concentration.
