Introduction: Cervical cancer is the third most common malignant tumor in the female population and the fourth cause of death from cancer in women in Brazil. The squamocolumnar junction and the transformation zone concentrate 90% of pre-invasive and invasive cervical lesions. Objective: To evaluate the prevalence of cytology without cells of the squamocolumnar junction and feasibility of active search. Methods: Cross-sectional study at a university hospital between 2017 and 2018. The prevalence of cytology without squamocolumnar junction cells was calculated. A convenience sample was obtained and mean age and relationship with presence of transformation zone cells were calculated. An active search was performed and cytology collected, with estrogen preparation if indicated. Medical records of the other women were analyzed. Results: Squamocolumnar junction cells were not found in 28.84% of samples. Mean age was 53 years, without association with presence of squamocolumnar junction cells (p=0.409). Seventy-six women returned, 36 of which (47.37%) used estrogen. Level 2 or 3 cervical intraepithelial neoplasia, microinvasive carcinoma or cancer was not identified. A total of 134 medical records were analyzed; only 36 women (26.87%) completed screening. Conclusions: The presence of squamocolumnar junction cells indicates quality of cytology; the use of estrogen in postmenopausal women favors its collection. There were difficulties in active search. An immediate repetition of cytology should be considered.

Introdução: O câncer de colo uterino é o terceiro tumor maligno mais frequente na população feminina e a quarta causa de morte de mulheres por câncer no Brasil. A junção escamo-colunar e a zona de transformação concentram 90% das lesões pré-invasoras e invasoras cervicais. Objetivo: Avaliar prevalência de colpocitologias sem células da junção escamo-colunar e a viabilidade de busca ativa. Métodos: Estudo transversal em hospital universitário entre 2017 e 2018. Calculada prevalência de citologias sem células da junção escamo-colunar. Obtida amostra por conveniência, calculada média de idade e relação com a presença da junção escamo-colunar. Realizada busca ativa e colhidas citologias com preparo estrogênico, se indicado. Analisados os prontuários das demais mulheres. Resultados: A prevalência de ausência de células da junção escamo-colunar foi de 28,84%. A média de idade foi 53 anos, sem associação com presença da junção escamo-colunar (p=0,409). Retornaram 76 mulheres e 36 (47,37%) usaram estrogênio. Não identificamos neoplasia intraepitelial cervical graus 2 ou 3, carcinoma microinvasor e câncer. Analisados 134 prontuários, dos quais apenas 36 mulheres (26,87%) concluíram o rastreio. Conclusões: A presença de células da junção escamo-colunar indica qualidade da coleta, e o uso de estrogênio na pós-menopausa favorece sua obtenção. Houve dificuldade de busca ativa. A repetição imediata da citologia deve ser considerada.

ABSTRACT Objective: Diabetes mellitus (DM) has a high healthcare system cost worldwide. Educational strategies are important to improve self-care and control this disease. This study aimed to evaluate satisfaction and clinical efficacy of a Short Message Service (SMS) educational intervention in self-care and nutrition at a Brazilian university hospital. Materials and methods: We conducted a trial of educational intervention and assigned eligible patients with DM to either receive weekly educational SMS for 6 months (intervention group [IG]) or no SMS at all (control group). A satisfaction questionnaire was applied before and after the intervention in both groups. Laboratory (fasting glucose, hemoglobin [Hb] A1c, total cholesterol, triglycerides, high-density lipoprotein, and low-density lipoprotein) and clinical (blood pressure) data were also collected. Data were analyzed using nonparametric tests with the Statistical Package for the Social Sciences. Results: We included 128 patients (64 in each group). Responses to the satisfaction questionnaire with self-care and healthcare professionals from 112 patients revealed an improvement in the perception of receiving information regarding helpful eating habits and in healthy eating behavior and an improvement in satisfaction with their diabetes care in the IG. In the post-intervention period, improved systolic blood pressure and HbA1c levels were observed in the IG as illustrated by delta % (post-intervention minus pre-intervention data divided by pre-intervention data multiplied by 100) reductions of 2.3% and 3.9%, respectively Conclusion: SMS intervention was useful as an educational tool for improving satisfaction and glycemic and blood pressure control of patients with DM observed at a Brazilian university hospital.

ABSTRACT BACKGROUND AND OBJECTIVES: Pain and stress are the main factors stimulating behavioral, physiological, and hormonal changes in preterm newborns (PTNB) admitted to a Neonatal Intensive Care Unit (NICU); therefore, the systematic multidimensional assessment of pain at the bedside becomes an essential tool for reducing the impact of brain stimulation, as it guides the appropriate treatment. The objectives of this study were to assess the pain at the bedside of PTNB submitted to peripheral venipuncture or diaper change and to describe the measures for pain relief. METHODS: Longitudinal study, with a prospective cohort of 25 PTNB, carried out in an NICU in the city of Rio de Janeiro. Pain assessment at the bedside was performed at three different times, using the Neonatal Infant Pain Scale (NIPS) and Premature Infant Pain Profile (PIPP), when subjected to peripheral venipuncture for infusion therapy and diaper changes. The scores of the scales were analyzed using the Chi-square test. RESULTS: In the puncture group, there was pain and increased intensity. In the diaper group, three PTNB showed pain at the third assessment. During peripheral venipuncture, the non-pharmacological measures were used: oral 25% glucose, non-nutritive suction and a combination of the two. CONCLUSION: Assessing pain at the bedside using scales helps nursing professionals in pain prevention and treatment, avoiding altered responses of newborns in the face of procedures.

RESUMO JUSTIFICATIVA E OBJETIVOS: A dor e o estresse são os principais fatores de estímulo às alterações comportamentais, fisiológicas e hormonais dos recém-nascidos pré-termos (RNPT) internados na Unidade de Terapia Intensiva Neonatal (UTIN); portanto, a avaliação multidimensional sistemática da dor se torna uma ferramenta imprescindível para a redução do impacto da estimulação cerebral, visto que direciona para o adequado tratamento. Os objetivos deste estudo foram avaliar a dor à beira do leito de RNPT submetidos à punção venosa periférica ou à troca de fraldas e descrever as medidas para o alívio da dor. MÉTODOS: Estudo longitudinal, com uma coorte prospectiva de 25 RNPT, realizado em uma UTIN no município do Rio de Janeiro. Foi realizada avaliação da dor à beira do leito em três momentos distintos, com a Neonatal Infant Pain Scale e Premature Infant Pain Profile, quando submetidos à punção venosa periférica para terapia infusional e troca de fraldas. As pontuações das escalas foram analisadas por meio do teste Qui-quadrado. RESULTADOS: No grupo punção, houve presença de dor e aumento da intensidade. No grupo fralda, três RNPT mostraram presença de dor na terceira avaliação. Durante a punção venosa periférica, foram utilizadas as medidas não farmacológicas; glicose oral a 25%, sucção não nutritiva e a combinação das duas. CONCLUSÃO: A avaliação da dor à beira do leito por meio de escalas auxilia os profissionais de enfermagem na prevenção e tratamento da dor, evitando respostas alteradas do recém-nascido diante de procedimentos.

Introduction: Infections caused by Chlamydia trachomatis (CT) and Human Papilloma Virus (HPV) are among the most prevalent sexually transmitted infections (STIs) worldwide. CT infection in women living with the human immunodeficiency virus (HIV) can facilitate HIV transmission by increasing HIV shedding in cervicovaginal secretions. The prevalence of Human papillomavirus (HPV) infection is higher in women living with HIV when compared to HIVnegative women, even when comparing those with the same sociodemographic characteristics. Generally, they have a high viral load and a higher persistence of viral infection, which increases the risk of developing premalignant and malignant lesions in the lower genital tract. Objective: To evaluate the frequency of CT and High-Risk HPV (HR-HPV) infection among women living with HIV and the association with sociodemographic, behavioral and clinical characteristics. Methods: Cross-sectional study carried out with a population of 66 non-pregnant women aged between 18 and 70 years living with HIV and/or acquired immunodeficiency syndrome (AIDS) at the Hospital Universitário Antônio Pedro, Universidade Federal Fluminense (UFF), Niterói (RJ), Brazil, between the period of March 1, 2018 and October 31, 2018. A standardized questionnaire was applied including sociodemographic and behavioral characteristics, and clinical information (use of oral contraceptives, Antiretroviral Therapy (ART), cluster of differentiation 4 (CD4) cell count, and viral load). Endocervical samples were collected for CT (COBAS 4800® system, Roche) and HPV (COBAS® HPV test, Roche) detection. Fisher's Exact Test was used to assess the association between variables. Regression analyses were performed using the logistic model in order to identify the factors associated with the outcomes of interest. Results: A frequency of 1.5% for CT and 21.2% for HR-HPV was found. Age was the single factor that presented statistical significance associated with HR-HPV infection. Conclusion: Our study showed that some women living with HIV promote risky behavior which could facilitate the acquisition of other STIs, such as HPV and CT infection. Some of them, with detected viral load, were not using condoms even with HIV-negative partners. These results may suggest that in addition to treatment and follow-up of women living with HIV, STIs counseling and guidance may play an important role in the control of STIs in this population

Introdução: As infecções causadas por Chlamydia trachomatis e por papilomavírus humano (HPV) estão entre as infecções sexualmente transmissíveis (IST) mais prevalentes em todo o mundo. A infecção por Chlamydia trachomatis em mulheres que vivem com HIV pode facilitar a transmissão do HIV, aumentando a disseminação do HIV cérvico-vaginal. A prevalência da infecção pelo HPV é maior em mulheres vivendo com HIV quando comparadas às mulheres HIV negativas, mesmo quando comparadas àquelas com as mesmas características sociodemográficas. Geralmente apresentam carga viral elevada e maior persistência de infecção viral, o que aumenta o risco de desenvolver lesões pré-malignas e malignas no trato genital inferior. Objetivo: Avaliar a frequência de infecção por Chlamydia trachomatis e HPV de alto risco (HR-HPV) em mulheres vivendo com HIV e sua associação com características sociodemográficas, comportamentais e clínicas. Métodos: Estudo transversal realizado com uma população de 66 mulheres não gestantes de 18 a 70 anos vivendo com HIV e/ou AIDS no Hospital Universitário Antônio Pedro, Universidade Federal Fluminense ­ Niterói (RJ), Brasil, entre 1º de março e 31 de outubro de 2018. Aplicou-se um questionário padronizado incluindo características sociodemográficas e comportamentais e informações clínicas (uso de anticoncepcionais orais, terapia antirretroviral, contagem de células CD4 e carga viral). Amostras endocervicais foram coletadas para detectar Chlamydia trachomatis (COBAS 4800® Roche) e HPV (COBAS ® HPV Roche). O teste exato de Fisher avaliou a associação entre as variáveis. As análises de regressão foram realizadas por meio do modelo logístico, a fim de identificar os fatores associados aos desfechos de interesse. Resultados: Encontrou-se frequência de 1,5% para Chlamydia trachomatis e 21,2% para HR-HPV. A idade foi o único fator que apresentou significância estatística associada à infecção por HR-HPV. Conclusão: Nosso estudo mostra que algumas mulheres vivendo com HIV praticam comportamentos de risco que podem facilitar a aquisição de outras IST, como a infecção por HPV e Chlamydia trachomatis. Algumas delas com carga viral detectada não usavam preservativo, mesmo com parceiros HIV negativos. Esses resultados podem sugerir que, além do tratamento e acompanhamento de mulheres vivendo com HIV, o aconselhamento e a orientação para IST podem desempenhar um papel importante no controle das IST nessa população.

ABSTRACT Objective The consequences of sleep deprivation in type 1 diabetes (T1D) patients are poorly understood. Our aim was to determine how sleep disorders influence lipid profile and insulin sensitivity in T1D patients. Materials and methods This was a cross-sectional study at a public university hospital. Demographic information and medical histories were obtained during regular scheduled visit of T1D patients to the outpatient clinic. Insulin sensitivity was obtained using the estimated glucose disposal rate (eGDR) formula. Sleep quality was assessed using the Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale and Berlin Questionnaire. Results The adult participants (n = 66, 62% women) had a median age of 28.0 years (interquartile range 21.8-33.0). Six patients (9%) had metabolic syndrome according to the International Diabetes Federation criteria. Thirty patients (46%) were considered poor sleepers according to the Pittsburgh Sleep Quality Index. The LDL-c and total cholesterol levels of poor sleepers were higher than those of good sleepers (103 v. 81; p = 0.003 and 178.0 v. 159.5 mg/dL; p = 0.009, respectively). Three patients (4%) were at high risk of obstructive sleep apnea syndrome (OSAS) according to the Berlin Questionnaire. The eGDR was lower in the group of patients with high probability of having OSAS (6.0 v. 9.1;p = .03). Conclusions Poor subjective quality of sleep and higher risk of OSAS were correlated with a worsened lipid profile and decreased insulin sensitivity, respectively. Therefore, T1D patients with sleep disturbances might have an increased cardiovascular risk in the future.

OBJECTIVES: This study aimed to evaluate the potential relationship between oxidative stress, dietary intake, and serum levels of antioxidants in patients with a complete hydatidiform mole (CHM) compared with controls. METHODS: This was an observational cross-sectional study conducted in Rio de Janeiro, Brazil. A total of 140 women were enrolled in this study and divided into four groups: 43 patients with CHM, 33 women who had had an abortion, 32 healthy pregnant women, and 32 healthy non-pregnant women. All participants underwent blood sampling, assessment using a semiquantitative food frequency questionnaire, and anthropometric measurement. Blood samples were collected after overnight fasting (10-12 h). Vitamin levels (A, C, and E) were determined by ultra-performance liquid chromatography, and gamma-glutamyl transferase levels were assessed using an automated quantitative analysis system (Dimension®, Siemens). RESULTS: Although all groups showed sufficient serum vitamin A and E levels, the participants had inadequate dietary intake of these vitamins. Conversely, all groups had an insufficient serum level of vitamin C, despite adequate intake. The gamma-glutamyl transferase values did not differ significantly among the groups. However, elevated serum levels of this enzyme were observed in several patients. CONCLUSIONS: All groups exhibited high levels of oxidative stress, as evaluated by gamma-glutamyl transferase levels, and had inadequate intake of antioxidant vitamins. Therefore, the high exposure to oxidative stress found in our study, even in healthy pregnant and non-pregnant women, may increase the incidence of CHM in this region.

Objective: to evaluate methods of elderly height estimation attended at the Nutrition ambulatory. Method: a total of 43 elderly individuals of both genders were evaluated during nutrition consultations. Sociodemographic data were collected from charts and height, knee height, arms wingspan and semi-span were measured. Statistical analysis were made through Bland-Altman test to evaluate concordance among statures estimated by predictive formulas and the height measured. Results: the values ​​found were: height measured in meters 1.53 (±0.08), height estimated by the wingspan 1.60 (±0.10), by the semi-span 1.61 (±0.11) and by the knee height 1.56 (±0.10). According to the Bland-Altman graph, the height estimated by knee height showed a better agreement with the measured height. Conclusion: according to this study results, poor predictive formulas concordance in height estimation in elderly, using the measures: arms wingspan and semi-span with real stature measured were observed. Knee height, using Chumlea formula, presented the best concordance with measured stature and seems to be a good way for stature estimation at the studied population.

Objetivo: avaliar a concordância entre os métodos de estimativa de estatura com a estatura aferida de idosos atendidos em ambulatório de nutrição. Método: foram avaliados 43 idosos, de ambos os sexos, durante as consultas de nutrição, tendo sido coletados dados sociodemográficos dos prontuários e aferidas a estatura, altura do joelho, envergadura e semienvergadura dos braços. A análise estatística dos dados foi feita pelo teste de Bland-Altman para avaliar a concordância entre as estaturas estimadas pelas fórmulas preditivas e a estatura aferida. Resultados: os valores encontrados foram: estatura aferida em metros 1,53 (±0,08), estatura estimada pela envergadura 1,60 (±0,10), pela semienvergadura 1,61 (±0,11) e pela atura do joelho 1,56 (±0,10). De acordo com o gráfico de Bland-Altman a estatura estimada pela altura do joelho apresentou melhor concordância com a estatura aferida. Conclusão: com os resultados encontrados neste trabalho, observamos que as fórmulas preditivas para estimativa de estatura em idosos, que utilizam envergadura e semienvergadura dos braços não apresentaram boa concordância com a estatura aferida. Já a altura do joelho, utilizando a fórmula de Chumlea, apresentou a melhor concordância com a estatura aferida e parece ser a uma boa maneira para estimar a estatura da população estudada.

Abstract INTRODUCTION: Dengue is one of the most important mosquito-borne infections. Severe cases are more frequently observed in adults. However, in 2008, the State of Rio de Janeiro, Brazil, experienced a severe dengue epidemic that primarily affected children and caused many cases of dengue hemorrhagic fever (DHF) and death. METHODS: A cross-sectional analytical study was conducted to examine laboratory diagnosis and clinical epidemiologic factors for confirmed dengue cases in patients aged less than 16 years, from January to June 2008, at a municipal hospital in the City of Rio de Janeiro, Brazil. Variables associated with severe outcomes and P values less than .05 were evaluated by means of a logistic regression model. RESULTS: Of the 419 dengue cases studied, 296 were classified as DHF and 123 as classical dengue. Six patients who had DHF died. In multivariate analysis, some laboratory and clinical variables were independently associated with DHF: age 5 years or older (odds ratio [OR], 4.94; 95% confidence interval [CI], 1.30-18.71), abdominal pain (OR, 8.59; 95% CI, 3.17-23.27), hepatomegaly (OR, 15.87; 95% CI, 5.38-46.85), and positive tourniquet test (OR, 10.84; 95% CI, 3.96-29.71). Hypoalbuminemia occurred more frequently than hemoconcentration in DHF cases, and high aminotransferase levels were associated with severity. CONCLUSIONS: Age greater than 5 years, abdominal pain, painful hepatomegaly, and positive tourniquet test were predictors of DHF. The high frequency of hepatic impairment suggests that acetaminophen should be avoided in severe cases of dengue.

Resumo O tratamento da aids implica a utilização de diversos medicamentos que compõem a terapia antirretroviral, sendo o controle logístico monitorado por um sistema nacional informatizado de dispensação, o Sistema de Controle Logístico de Medicamentos (SICLOM). O objetivo foi investigar a utilização da terapia antirretroviral de pacientes de dois hospitais universitários no Estado do Rio de Janeiro a partir do SICLOM. Foi realizado um estudo seccional com coleta de dados sociodemográficos e de dispensação, a partir do SICLOM. A avaliação da posse para estimativa de pacientes não aderidos foi realizada através do indicador de proporção de dias cobertos (PDC). Foram incluídos 538 pacientes com cadastro ativo no SICLOM, maiores de 18 anos de ambos os sexos. O ARV mais utilizado em ambos os hospitais foi lamivudina, dentre 58 esquemas diferentes identificados. A maior parte dos pacientes utilizava esquemas classificados como de primeira linha de tratamento. Em média, a proporção de dias cobertos (posse) pelo tratamento foi 88% (± 0,16). A linha de tratamento mostrou associação estatística com a posse, sendo observado melhor PDC 91% (p < 0,001) para os esquemas resgate. Este estudo corroborou o SICLOM como uma boa fonte para conhecimento do perfil de utilização de ARV.

Abstract Treatment of AIDS involves the use of the cocktail of drugs that make up the antiretroviral therapy. Its logistic control is monitored by a computerized national system of dispensation, the Logistic Control System of Medication (SICLOM). This study aimed to investigate, by means of SICLOM data, the use of antiretroviral therapy in patients treated at two University Hospitals in the state of Rio de Janeiro. A cross-sectional study was conducted with sociodemographic and dispensation data collected from SICLOM. The evaluation of drug ownership was done by calculating the Proportion of Days Covered (PDC). Five hundred and thirty-eight patients of both genders with active registration in SICLOM and over 18 years of age were included. The ART most used in both hospitals was lamivudine, considering the total of 58 different schemes identified. The mean of possession of groups was 88% (± 0,16). The factor associated with possession of drugs was the ART scheme, with PDC of 91% (p<0,001) for rescue schemes. This study confirmed that SICLOM was a reliable source to establish the profile of the population assisted.

Introdução: A adequação nutricional é uma terapêutica que pode diminuir as complicações e melhorar o resultado do tratamento do paciente na Unidade de Terapia Intensiva. Método: Estudo de coorte retrospectivo, sendo os dados obtidos nas fichas de pacientes atendidos entre agosto de 2013 e outubro de 2014, em uso exclusivo de nutrição enteral. Foram coletados: diagnóstico principal; uso de drogas vasoativas; dependência de ventilação mecânica e de hemodiálise; exames bioquímicos; dados antropométricos; dia do início e aportes energéticos e proteicos nos 3o e 7o dias suporte nutricional; motivos para o atraso na introdução e evolução do suporte e desfecho clínico (óbito ou alta). Foram obtidos também os déficits energéticos e proteicos cumulativos. Os dados foram analisados com o programa SPSS versão 18.0 por meio da estatística descritiva, sendo significativos os valores de p<0,05. Resultados: Foram obtidos dados de 74 pacientes. O tempo de início da terapia nutricional esteve de acordo com o preconizado. Somente as recomendações energéticas foram atingidas dentro do prazo estabelecido. O déficit calórico diário foi menor do que o relatado pela literatura, já para a proteína foi elevado. Os principais fatores que dificul- taram a adequação nutricional foram os relacionados às causas internas. A adequação energética não influenciou nos parâmetros bioquímicos, nem no desfecho da internação dos pacientes. Já os pacientes que atingiram a quota proteica apresentaram menores valores de leucócitos no desfecho e também houve menor número de óbitos quando comparados aos que não atingiram. Conclusões: A terapia nutricional instituída atendeu às recomendações preconizadas para a adequação energética. A oferta proteica esteve em desacordo com as necessidades estimadas.(AU)

Introduction: The nutritional adequacy is a therapy that can reduce complications and improve the outcome of patient care in the Intensive Care Unit. Methods: Retrospective cohort study, the data were obtained from patient records attended from August 2013 to October 2014, in exclusive use of nutrition enteral. There were collected: primary diagnosis; vasoactive drugs; dependence on mechanical ventilation and hemodialysis; biochemical tests; anthropometric data; day of start and energy and protein intakes at 3 and 7 days nutritional support; reasons for the delay in the introduction and evolution of support and clinical outcome (death or discharge). Also there were obtained cumulative energy and protein deficits. Data were analyzed with SPSS version 18.0 software using descriptive statistics, being significant p values <0,05. Results: It was obtained data from 74 patients. The onset of nutritional therapy time agreed with the recommendations. Only energy recommendations were reached within established. Daily calorie deficit was lower than that reported in the literature, as for the protein was high. The main factors that hampered the nutritional adequacy were related causes interns. An adequate energy intake did not influence the biochemical parameters, or the outcome of the hospitalization of patients. Patients that reached the quota protein had lower leukocyte values in outcome and also fewer deaths when compared to those that not reached. Conclusions: Nutritional therapy instituted met the recommended recommendations for energy adequacy. The protein supply was at odds with estimated needs.(AU)

RESUMO: Objetivo: Descrever a metodologia de um estudo sobre associações entre crescimento intrauterino restrito (CIUR) e prevalência de sobrepeso, obesidade e hipertensão arterial em escolares. Métodos: O estudo, conduzido em dois estágios, foi desenvolvido em 2 escolas municipais de Niterói (RJ) de junho a dezembro de 2010, sendo elegíveis todos os escolares de 6 a 14 anos. O primeiro estágio consistiu em um inquérito nutricional e de potenciais fatores de risco. Foram aplicados questionários aos responsáveis e adolescentes. Concomitantemente, foram selecionados os participantes de um estudo caso-controle, com casos prevalentes definidos como todos os escolares que apresentaram excesso de peso (Z-score de índice de massa corporal -IMC/idade/sexo > +1,00). O grupo controle consistiu em uma amostra aleatória da população de estudo do inquérito, o que permitiu o cálculo de razões de prevalências. Foram realizados bioimpedância elétrica, exames de sangue, ultrassonografia da carótida e entrevistas. As variáveis proxy de CIUR foram definidas a partir de informações sobre peso ao nascer (PN) e idade gestacional (IG). Adicionalmente, foram coletadas informações sobre os dois primeiros anos de vida dos escolares a partir de seus prontuários médicos. Resultado s: Entre os 1.040 escolares elegíveis, participaram do estudo 795 escolares (76,4%). A taxa de retorno do questionário enviado para os responsáveis foi de 85,1%. Para o estudo caso-controle, 62,5% (n = 363) dos selecionados participaram, resultando em uma razão caso:controle de 1:1,8. Foram localizados 55,8% (n = 444) dos prontuários, dos quais em 65,7% (n = 292) foram coletadas informações dos primeiros anos de vida. Conclusão: O presente estudo permitirá a análise de múltiplos desfechos e exposições relacionados ao CIUR e alterações metabólicas.

ABSTRACT: Objective: To describe the methodological features of a study on the association between restricted intrauterine growth and prevalence of overweight, obesity and hypertension in school aged children. Methods: The study was conducted in two stages in two public schools in Niterói (RJ), from June through December 2010. All students aged 6 to 14 years were eligible to participate. The first stage consisted of an interview to collect information on demographic variables, diet and other variables. A sample was selected for the second stage, in order to conduct an equivalent of a case-cohort study. There was an interval of about 15 days between the two stages. Cases were overweight students, defined as a Z-score for BMI/age/sex > +1.00 in the first stage. Controls were selected by using a random schedule in which the sample frame was the whole cohort. Bioelectrical impedance analysis, carotid ultrasound to measure intimal-medial thickness, blood measurements and interviews were obtained. Gestational age and weight at birth were used to define proxy variables of restricted intrauterine growth. Early health information was obtained from medical registers. Results: The study participation was 76.4% (n = 795) out of 1,040 eligible to participate). 85.1% of parent's questionnaires were returned. 62.5% of the eligible children participated in the case-control study (case: control ratio = 1:1.8). Early life health information was obtained from 292 children. Conclusion: The present study has the potential to provide important information about multiple outcomes and exposures related to restricted intrauterine growth and metabolic abnormalities.

A utilização de agentes iodados em exames radiológicos pode causar nefropatia induzida porcontraste (NIC) na presença de fatores de risco clássicos, como doença renal prévia e diabetes. Recentemente,níveis séricos elevados de proteína C-reativa ultrassensível (PCR-us) têm sido descritos como indicadores de maior risco de NIC. Independente da ocorrência de NIC, a PCR-us pode elevar-se após exames contrastados.Objetivo: Investigar o comportamento da PCR-us em pacientes submetidos à administração parenteral de agentede contraste iodado. Métodos: Estudo observacional, transversal, prospectivo, realizado no Hospital Universitário Antônio Pedro, de 2007 a 2014, envolvendo 51 pacientes, 30 homens e 21 mulheres, média de idade 60,19±20,0 anos, submetidos aexames com contraste de baixa osmolalidade (Iopamidol 612 mg/mL).Resultados: NIC ocorreu em 15 pacientes (29,4%). Não houve correlação entre a PCR-us aumentada e a ocorrência de NIC. O aumento percentual da PCR-us foi significativamente maior entre os pacientes submetidos ao cateterismocardíaco (p=0,0044). O aumento médio da PCR-us nos pacientes submetidos ao cateterismo cardíaco e naquelessubmetidos à administração do contraste iodado por veia periférica foi 100,3% e 13,8%, respectivamente.Conclusão: Os achados sugerem que o aumento da PCR-us após cateterismo cardíaco não pode ser atribuído aoagente de contraste iodado...

Background: The use of iodinated agents in radiological studies can cause contrast-induced nephropathy (CIN) in the presence of classic risk factors such as previous renal disease and diabetes. High serum levels of high-sensitivity C-reactive protein (CRP) have been described as indicators of increased risk of CIN. Regardless of the occurrence of CIN, hs-CRP may rise after contrast studies. Objective: To investigate the behavior of hs-CRP in patients undergoing parenteral administration of iodinated contrast agent. Methods: Observational cross-sectional prospective study held at Hospital Universitário Antônio Pedro from 2007 to 2014 involving 51 patients, 30 men and 21 women, mean age 60.19±20.0, undergoing tests with low-osmolality contrast (Iopamidol 612mg/ml).Results: CIN occurred in 15 patients (29.4%). There was no correlation between increased hs-CRP and occurrence of CIN. The percentage increase in hs-CRP was significantly higher among patients undergoing cardiac catheterization (p=0.0044). The mean increase in hs-CRP in patients undergoing cardiac catheterization and in those submitted to administration of iodinated contrast by peripheral vein was 100.3% and 13.8%, respectively.Conclusion: The findings suggest that increased hs-CRP after cardiac catheterization cannot be attributed to iodinated contrast agente...

Os ensaios clínicos constituem-se numa poderosa ferramenta para a avaliação de intervenções para a saúde. Na avaliação crítica de um ensaio clínico randomizado, devemos considerar o padrão de recrutamento e seleção, e os critérios de inclusão e exclusão. Trabalhos com critérios muito rígidos de inclusão são mais restritivos na generalização das conclusões. Cabe ao leitor decidir se as diferenças entre a população selecionada no estudo e a população que lhe interessa são importantes ou não.

Clinical trials constitute a powerful tool for the evaluation of interventions for health. In a critical analysis of a randomized clinical trial, we must consider the pattern of recruitment and selection, and the inclusion and exclusion criteria. The trials with very strict inclusion criteria are more restrictive in the generalization of the findings. The reader must decide whether the differences between the selected population in the study and the population of interest are important or not.

Fundamento: A Síndrome Metabólica (SM) é uma agregação de fatores de risco que aumenta a incidência de eventos cardiovasculares e Diabete Melito (DM). O envelhecimento da população vem acompanhado de maior prevalência de SM, que varia dependendo da população estudada e do critério diagnóstico utilizado. Objetivo: Determinar a prevalência de SM em idosos por quatro critérios diagnósticos e a concordância entre esses. Métodos: Estudo transversal realizado em 243 indivíduos acima de 60 anos (180 mulheres) em Niterói (RJ). Foram avaliados através de exame clínico glicemia jejum, insulinemia jejum, perfil lipídico e medidas antropométricas - peso, estatura, circunferência abdominal e relação cintura/quadril. A prevalência de SM foi estimada utilizando critérios diagnósticos da Organização Mundial da Saúde (OMS) modificado, National Cholesterol Education Program - Adult Treatment Panel III (NCEP-ATPIII), International Diabetes Federation (IDF) e Joint Interim Statement (JIS). Resultados: A prevalência foi elevada pelos quatro critérios, OMS (51,9%), NCEP-ATPIII (45,2%), IDF (64,1%) e JIS (69,1%), e a concordância entre os critérios diagnósticos pelo índice kappa foi moderada em quase todas as comparações OMS vs. IDF (k = 0,47; intervalo de confiança (IC) 95%, 0,35 - 0,58); OMS vs. NCEP-ATPIII (k = 0,51; IC 95%, 0,40 - 0,61); OMS vs. JIS (k = 0,45; IC 95%, 0,33 - 0,56); IDF vs. NCEP-ATPIII (k = 0,55, IC 95%, 0,45 - 0,65) e NCEP-ATPIII vs. JIS (k = 0,53; IC 95%, 0,43 - 0,64), exceto entre IDF vs. JIS (K= 0,89; IC 95%, 0,83 - 0,95), considerada boa. Conclusão: A prevalência de SM foi elevada pelos quatro critérios diagnósticos, principalmente pelo JIS. Houve uma boa concordância entre os critérios ...

Background: Metabolic syndrome (MS) is an aggregation of risk factors that increase the incidence of cardiovascular events and diabetes mellitus (DM). Population aging is accompanied by higher prevalence of MS, which varies depending on the population studied and the diagnostic criteria used. Objective: To determine prevalence of MS in the elderly using four diagnostic criteria and agreement between them. Methods: Cross-sectional study on 243 patients older than 60 years (180 women) in Niterói, RJ. They were evaluated by clinical examination, fasting glucose, fasting insulin, lipid profile and anthropometric measurements - weight, height, waist circumference and waist/hip ratio. Prevalence of MS was estimated by World Health Organization (WHO) modified, National Cholesterol Education Program - Adult Treatment Panel III (NCEP-ATP III), International Diabetes Federation (IDF) and Joint Interim Statement (JIS) criteria. Results: Prevalence was high with the four criteria WHO (51.9%), NCEP-ATPIII (45.2%), IDF (64.1%) and JIS (69.1%), and agreement between criteria by kappa was moderate in almost all comparisons WHO vs. IDF (k = 0.47;95% confidence interval (CI), 0.35 to 0.58); WHO vs. NCEP-ATPIII (k = 0.51; 95% CI, 0.40 to 0.61); WHO vs. JIS (k = 0.45; 95% CI, 0.33 to 0.56); IDF vs. NCEP-ATPIII (k = 0.55; 95% CI, 0.45 to 0.65) and NCEP-ATPIII vs. JIS (k = 0.53; 95% CI, 0.43-0.64), except between IDF vs. JIS (K = 0.89;95% CI, 0.83 to 0.95), which was considered good. Conclusion: Prevalence of MS was high with the four diagnostic criteria, mainly by JIS. There was good agreement between JIS and IDF criteria and moderate among the others. .

SUMMARY High-risk human papillomavirus (hr-HPV) infection is necessary but not sufficient for cervical cancer development. Recently, P16INK4A gene silencing through hypermethylation has been proposed as an important cofactor in cervical carcinogenesis due to its tumor suppressor function. We aimed to investigate P16INK4A methylation status in normal and neoplastic epithelia and evaluate an association with HPV infection and genotype. This cross-sectional study was performed with 141 cervical samples from patients attending Hospital Moncorvo Filho, Rio de Janeiro. HPV detection and genotyping were performed through PCR and P16INK4A methylation by nested-methylation specific PCR (MSP). HPV frequency was 62.4% (88/141). The most common HPV were HPV16 (37%), HPV18 (16.3%) and HPV33/45(15.2%). An upward trend was observed concerning P16INK4A methylation and lesion degree: normal epithelia (10.7%), low grade lesions (22.9%), high grade (57.1%) and carcinoma (93.1%) (p < 0.0001). A multivariate analysis was performed to evaluate an association between methylation, age, tobacco exposure, HPV infection and genotyping. A correlation was found concerning methylation with HPV infection (p < 0.0001), hr-HPV (p = 0.01), HSIL (p < 0.0007) and malignant lesions (p < 0.0001). Since viral infection and epigenetic alterations are related to cervical carcinoma, we suggest that P16INK4A methylation profile maybe thoroughly investigated as a biomarker to identify patients at risk of cancer. .

RESUMO É reconhecido que infecções por papilomavírus humanos de alto risco (HPV) são causa necessária, mas não suficiente para o desenvolvimento do câncer cervical. Recentemente, estudos de silenciamento gênico apontaram que a hipermetilação do gene p16INK4A é importante co-fator para a carcinogênese cervical, eliminando a função supressora de tumor da proteína p16 em lesões malignas. Entretanto poucos estudos avaliaram a relação da metilação com a progressão da doença. Nosso objetivo foi investigar o padrão de metilação do gene P16INK4A em diferentes graus de lesão cervical e sua associação com a infecção por diferentes tipos de HPV. Nosso estudo de corte transversal avaliou 141 amostras cervicais de pacientes atendidas no Hospital Moncorvo Filho, Rio de Janeiro. A detecção e tipagem do HPV foi realizada pela técnica de reação em cadeia da polimerase (PCR), e a metilação do gene P16INK4A pela PCR-metilação específica em formato nested (MSP). A frequência de HPV foi de 62,4% (88/141). O tipo mais prevalente foi o HPV16 (37%), seguido pelo HPV18 (16,3%) e HPV33/45 (15,2%). Curva ascendente foi observada quanto ao padrão de metilação do gene P16INK4A e o grau da lesão: a metilação foi identificada em somente 10,7% das amostras de epitélio normal, em 22,9% das lesões de baixo grau, em 57,1% das lesões de alto grau e em 93,1% dos carcinomas (p < 0,0001). Foram feitas análises univariada e multivariada a fim de correlacionar metilação, idade, exposição ao tabaco, infecção e genótipo de HPV. Foi encontrada correlação da metilação com a infecção pelo HPV (p < 0,0001), genótipos de alto risco (p = 0,01), ...

PURPOSE: To evaluate whether the prolonged consumption of flaxseed minimize the factors that trigger MS in healthy rats. METHODS: Pregnant rats were divided immediately after delivery into two groups during the lactation period, a control group (CG) receiving casein-based diet with 17% of protein, and a Flaxseed group (FG) with casein-based diet plus 25% of flaxseed. At weaning, 12 offspring of each group continued to receive the same feed but with 10% of protein up to 200 days old. RESULTS: FG showed a significant reduction in body weight (p=0.001), total cholesterol levels (p<0.0001), triglycerides (p=0.0001), and glucose (p=0.001). CONCLUSION: The flaxseed alters the indicators related to development of metabolic syndrome, because it has beneficial effects on lipids and glucose profiles and prevents the excess of body weight gain.

OBJETIVO: Avaliar se o consumo prolongado de linhaça pode minimizar os fatores que desencadeiam síndrome metabólica em ratos fêmeas saudáveis. MÉTODOS: Ratos fêmeas grávidas foram distribuidas após o parto em dois grupos durante o período de lactação: grupo controle (GC) recebendo dieta à base de caseína com 17% de proteína, e um grupo Linhaça (GL), com dieta à base de caseína adicionada de 25% de semente de linhaça. Ao desmame, 12 filhotes de cada grupo continuaram a receber as rações citadas acima, porém com 10% de proteína, até os 200 dias de vida. RESULTADOS: O GL mostrou uma redução significativa do peso corporal (p=0,001), no colesterol total (p<0,0001), triglicerídeos (p=0,0001) e na glicemia (p=0,001). CONCLUSÃO: A linhaça altera os indicadores relacionados ao desenvolvimento da síndrome metabólica por ter efeitos benéficos no perfil lipídico e glicêmico, e previne o excesso de ganho de peso corporal.

OBJETIVOS: Avaliar o efeito da semente de linhaça no crematócrito do leite de ratas e crescimento corporal dos filhotes durante a lactação. MÉTODOS: Utilizou-se 22 ratas Lister Hooded divididas em dois grupos: controle (GC, n = 11), que recebeu ração caseína com 17 por cento de proteína; e linhaça (GL, n = 11), que recebeu ração com 25 por cento de linhaça acrescida de 14 por cento de caseína, totalizando 17 por cento de proteína. Controlou-se o consumo de ração das ratas por gaiola individual, número de crias, e avaliou-se o crematócrito do leite materno e variação ponderal dos filhotes até idade de desmame. RESULTADOS: O GL foi semelhante ao GC no consumo de ração das ratas (GL = 76,46±31,87 g; GC = 76,7±33,36 g; p = 0,9613) e equivalente ao GC no número de crias (GL = 4,94±2,34; GC = 5,5±3,19; p = 0,435). O mesmo foi verificado no teor de gordura do leite materno (GL = 18,4±4,76; GC = 15,3±6,03; p = 0,204) e valor energético total (GL = 212,92±46,4; GC = 181,1±60; p = 0,1964). O GL assemelhou-se ao GC tanto no peso corporal dos filhotes ao desmame (GL = 37±6,96 g; GC = 32,6±7,5 g; p = 0,1817) quanto na evolução ponderal (GL = 31,8±7,0 g; GC = 27,7±7,5 g; p = 0,2104). CONCLUSÃO: Um total de 25 por cento de linhaça promoveu um crescimento adequado aos filhotes.

OBJECTIVES: To assess the effect of flaxseed on rat milk creamatocrit and its contribution to offspring weight gain during lactation. METHODS: The study was conducted with 22 Lister Hooded rats divided into two groups: Control Group (CG, n = 11), which received a casein-based diet with 17 percent protein, and Flaxseed Group (FG, n = 11), which received a 25 percent flaxseed diet supplemented with 14 percent casein, totaling 17 percent protein. Food consumption was controlled per individual cage and litter size. Maternal milk creamatocrit and offspring weight variation until weaning age were also evaluated. RESULTS: FG was similar to CG concerning food intake (FG = 76.46±31.87 g; CG = 76.7±33.36 g; p = 0.9613) and equivalent to CG concerning litter size (FG = 4.94±2.34; CG = 5.5±3.19; p = 0.435). The same was found for milk fat content (FG = 18.4±4.76; CG = 15.3±6.03; p = 0.204) and total energy value (FG = 212.92±46.4; CG = 181.1±60; p = 0.1964). FG was similar to CG both in offspring body weight at weaning (FG = 37±6.96 g; CG = 32.6±7.5 g; p = 0.1817) and in weight gain (FG = 31.8±7.0 g; CG = 27.7±7.5 g; p = 0.2104). CONCLUSION: A total of 25 percent flaxseed promoted an adequate offspring growth.
