A Síndrome da Imunodeficiência Adquirida (Aids) é uma doença do sistema imunológico humano causada pelo vírus da imunodeficiência humana (HIV). O HIV ataca células humanas responsáveis por defender o organismo de doenças, sendo os linfócitos T CD4+ os mais atingidos. A dor abdominal em paciente imunodeprimido evolui com difícil manejo diagnóstico, sendo mandatório ao cirurgião estar familiarizado com os diversos diagnósticos diferenciais e complicações secundárias da Aids. O presente trabalho teve como objetivo descrever os aspectos clínico-epidemiológicos de pacientes com Aids que evoluíram com abdome agudo e receberam tratamento cirúrgico no período de janeiro de 2001 a janeiro de 2011 no Hospital Universitário João de Barros Barreto. Foi um estudo observacional, retrospectivo, do tipo caso-controle, onde o grupo de casos foi constituído por pacientes com Aids que evoluíram com abdome agudo e o grupo controle, por pacientes que também evoluíram com abdome agudo, porém sem condição imunossupressora associada. Houve predominância do sexo masculino na proporção 4,5 homens para cada mulher no grupo com aids, porém com proporção similar nos controles. A maioria dos pacientes (87%) do grupo controle apresentou alguma alteração laboratorial, diferentemente do grupo com Aids, onde 38,5% dos pacientes tiveram resultado normal. A anemia esteve presente em 75% dos pacientes com Aids e a leucocitose em 80% do grupo controle. A causa mais frequente de abdome agudo na população com Aids foi perfuração intestinal (82,1%), enquanto no grupo controle foi obstrução intestinal (39,1%). Somente o quadro clínico de defesa abdominal e diminuição de ruídos hidroaéreos apresentaram diferença estatisticamente significativa (p<0.01). As alterações radiológicas mais frequentes foram distensão de alças em 87,2% dos pacientes com Aids e níveis hidroaéreos em 65,2% dos pacientes do grupo controle. A principal cirurgia realizada no grupo Aids foi a ressecção intestinal com reconstrução primária do trânsito (65,5%). As complicações cirúrgicas foram mais frequentes no grupo com Aids (87,2% com infecção de ferida operatória) e a causa predominante de óbito em ambos os grupos foi sepse a partir de foco abdominal (81% nos casos e 87,5% controles), inclusive nos pacientes ostomizados. A probabilidade de óbito nos casos com Aids foi superior em cerca de 2 vezes em relação aos controles. O tempo de internação e o tempo de pós-operatório até o óbito foi menor nos pacientes com Aids em comparação aos controles. Sendo fundamental a realização do estudo para melhorar o manejo e sobrevida dos pacientes com Aids.

PURPOSE: To evaluate the adequacy of gestational weight gain and to determine its association with maternal socioeconomic, demographic and nutritional factors and health care, to estimate the prevalence of low birth weight, macrosomia, preterm birth and cesarean delivery and to identify the association of these outcomes with the adequacy of weight gain. METHODS: A cross-sectional study was performed in 2009/2010 to obtain socioeconomic, demographic, nutritional, dietary and physical activity data of pregnant women assisted by primary health care in a municipality of the state of São Paulo. Subsequently, data were collected from the medical records to evaluate gestational weight gain. Type of delivery, birth weight and gestational age at delivery were obtained from the Livebirths Information System. Gestational weight gain was evaluated according to the recommendations of the Institute of Medicine (2009). Associations were investigated by comparing the frequencies and by logistic regression, with excessive weight gain (yes, no) and insufficient gain (yes, no) being the dependent variables. RESULTS: A total of 212 pregnant women were studied: 50.5% had excessive gain and 19.8% insufficient weight gain. Only prepregnancy nutritional status was associated with adequacy of weight gain: compared with normal weight, prepregnancy overweight women had a four-fold higher chance to gain excessive weight (OR 4.66, 95%CI 2.19-9.4). Nearly a third of babies were born by caesarian section, 5.7% were premature, 7.1% were underweight and 4.7% were macrosomic. There was no association between adequacy of gestational weight gain and these outcomes. CONCLUSION: The proportion of inadequate gestational weight gain was high. Overweight pregnant women have a four-fold higher chance to gain excessive weight, and priority should be given to actions promoting adequate prenatal weight gain.

Preeclampsia (PE) is a pregnancy specific syndrome characterized by a systemic inflammatory response, with higher intensity than that observed in normal pregnancy. Cells of the immune system, such as monocytes and granulocytes are endogenously activated and secrete high levels of free radicals and inflammatory cytokines. The objective of this study was to assess the activation state of monocytes from pregnant women with preeclampsia by endogenous expression of TLR2 e TLR4 receptors and to correlate the expression of TLR2 and TLR4 on monocytes surface of pregnant women with PE with the production of tumor necrosis factor-alpha (TNF- and interleukin-10 (IL-10) by these cells stimulated or not with peptidoglycan (PG) and lipopolysaccharide (LPS), as agonists agents of TLR2 and TLR4, respectively. We evaluated 15 pregnant women with PE, 15 normotensive pregnant women (NT) and 15 non-pregnant (NP). Peripheral blood monocytes were incubates in the presence or absence of LPS or PG. The supernatant obtained after 18h of culture was aspirated and used for TNF- and IL-10 determination by enzyme immunoassay (ELISA). The endogenous expression of TLR2 and TLR4 receptors was evaluated by flow cytometry. Our results showed significant highly concentrations of TNF- and TLR4 expression in monocytes of preeclamptic women when compared with NT and NP. Normal pregnant women presented higher levels of IL-10 in comparison with PE and NP groups. TLR2 expression was similar in the three groups studied. Therefore, our study highlights the important role of TLR4 in PE and the consequent high production of TNF- by monocytes of these patients, as well as the potential mechanism involving low levels of IL-10 in the pathophysiology of the disease. These observations demonstrate the strong link between the pathology of PE and the immune system of these patients

Experimental models are necessary to elucidate pathophysiological mechanisms not yet understood in humans. To evaluate the repercussions of the diabetes, considering two methodologies, on the pregnancy of Wistar rats and on the development of their offspring. In the 1st induction, female offspring were distributed into two experimental groups: Group streptozotocin (STZ, n=67): received the β-cytotoxic agent (100mg STZ/kg body weight - sc) on the 1st day of the life; and Non-diabetic Group (ND, n=14): received the vehicle in a similar time period. In the adult life, the animals were mated. After a positive diagnosis of pregnancy (0), female rats from group STZ presenting with lower glycemia than 120 mg/dL received more 20 mg STZ/kg (ip) at day 7 of pregnancy (2nd induction). The female rats with glycemia higher than 120mg/dL were discarded because they reproduced results already found in the literature. In the mornings of days 0, 7, 14 and 21 of the pregnancy glycemia was determined. At day 21 of pregnancy (at term), the female rats were anesthetized and killed for maternal reproductive performance and fetal development analysis. The data were analyzed using Student-Newman-Keuls, Chi-square and Zero-inflated Poisson (ZIP) Tests (p<0.05). STZ rats presented with increased rates of pre (STZ=22.0%; ND=5.1%) and post-implantation losses (STZ=26.1%; ND=5.7%), reduced rates of fetuses with appropriate weight for gestational age (STZ=66%; ND=93%) and reduced degree of development (ossification sites). Conclusion: Mild diabetes led a negative impact on maternal reproductive performance and caused intrauterine growth restriction and impaired fetal development
