Abstract: Programs for the prevention of mother-to-child transmission of HIV have reduced the transmission rate of perinatal HIV infection and have thereby increased the number of HIV-exposed uninfected (HEU) infants. Natural immunity to HIV-1 infection in both mothers and newborns needs to be further explored. In this study, we compared the expression of antiviral restricting factors in HIV-infected pregnant mothers treated with antiretroviral therapy (ART) in pregnancy (n=23) and in cord blood (CB) (n=16), placental tissues (n=10-13) and colostrum (n=5-6) samples and compared them to expression in samples from uninfected (UN) pregnant mothers (n=21). Mononuclear cells (MNCs) were prepared from maternal and CB samples following deliveries by cesarean section. Maternal (decidua) and fetal (chorionic villus) placental tissues were obtained, and colostrum was collected 24 h after delivery. The mRNA and protein expression levels of antiviral factors were then evaluated. We observed a significant increase in the mRNA expression levels of antiviral factors in MNCs from HIV-infected mothers and CB, including the apolipoprotein B mRNA-editing enzyme 3G (A3G), A3F, tripartite motif family-5α (TRIM-5α), TRIM-22, myxovirus resistance protein A (MxA), stimulator of interferon (IFN) genes (STING) and IFN-β, compared with the levels detected in uninfected (UN) mother-CB pairs. Moreover, A3G transcript and protein levels and α-defensin transcript levels were decreased in the decidua of HIV-infected mothers. Decreased TRIM-5α protein levels in the villi and increased STING mRNA expression in both placental tissues were also observed in HIV-infected mothers compared with uninfected (UN) mothers. Additionally, colostrum cells from infected mothers showed increased tetherin and IFN-β mRNA levels and CXCL9 protein levels. The data presented here indicate that antiviral restricting factor expression can be induced in utero in HIV-infected mothers. Future studies are warranted to determine whether this upregulation of antiviral factors during the perinatal period has a protective effect against HIV-1 infection.

Case Reports in Clinical Medicine (CRCM) , 2015, DOI: 10.4236/crcm.2015.43025
Abstract:
Introduction: Advances in prenatal imaging studies have allowed early diagnosis of Congenital Diaphragmatic Hernia (CDH), although neonatal mortality remains at high levels (60% survival). Despite advances, this study found delayed diagnosis, demonstrating subdiagnosis, possibly caused by lack of resources and/or prenatal diagnostic failure. Case Report 1: Infant, 4 months and 22 days old, dyspneic, cyanotic, with fever and vomiting for 3 days, treated as pneumonia. After the second chest radiography, a right CDH was revealed. Surgical correction was performed and removal of Meckel’s diverticulum was surgical findings. The patient was discharged on the 10th days after admission. Case Report 2: Infant, 11 months and 3 days old, distended abdomen, with fever and dyspnea for 2 days, treated as pneumonia. After the second chest radiography, a left CDH was revealed. The patient was submitted to surgery, intestinal loop incarceration without necrosis was observed, and the correction of CDH was performed. The patient was discharged on the 7th day after admission. Discussion: Three cases, between July 2012 and July 2013, were diagnosed at Dom Malam Hospital; 2 Cases of CDH, with delayed diagnosis, showed incidence of 66.66%. Delayed diagnosis of these patients with initial hypotheses of pneumonia demonstrated high risk, emphasizing the importance of diagnosis research through observation of the clinical course, the correct imaging interpretation, in order to establish early diagnosis and treatment.

Abstract: No período de fevereiro a julho de 1999, estudaram-se os efeitos de fontes salinas através da irriga o com água de barragem, rica em cloreto de sódio e em cloreto de magnésio, com níveis de condutividade elétrica de 0,5; 1,0; 2,0; 3,0; 6,0 e 9,0 dSm-1 sobre o crescimento inicial da gravioleira, Annona muricata L., cultivar Morada. Os resultados nos primeiros 150 dias, independentemente das fontes, indicam que área foliar e sua fitomassa cresceram com o aumento da salinidade das águas de 0,5 para 2,0 e até 3,0 dSm-1. No mesmo período, o índice de salinidade do substrato foi elevado para até fortemente salino, revelando que a gravioleira comportou-se como planta moderadamente tolerante aos sais durante o crescimento inicial. Apesar de a água rica em cloreto de magnésio ser a fonte que menos elevou a condutividade elétrica do substrato, foi a que mais contribuiu para a redu o das variáveis estudadas, indicando que as plantas foram mais sensíveis a sua toxidade em rela o à água de barragem e rica em cloreto de sódio.

Abstract: Perinatal asphyxia is defined as harm to the fetus or the newborn caused by hypoxia and/or ischemia of various organs with intensity to produce biochemical and/or functional changes. Understanding the risk factors for this clinical condition allows the identification of vulnerable groups, enabling an improvement in care planning in the perinatal period in neonatal intensive care units. In this sense, this research aimed to identify risk factors for perinatal asphyxia present in newborns term that showed record for this clinical condition. This was a cross-sectional, retrospective documentary, quantitative and descriptive, conducted from data from medical records of 55 infants admitted to a neonatal intensive care unit. As for maternal characteristics (78.0%) had between 16 and 35 years, only one child (53.0%) and (76.0%) had no prior history of miscarriage. As for pre-existing diseases or pregnancy (38.0%) developed by Hypertensive Pregnancy Specific disease (02.0%) were suffering from Hypertension and (02.0%) of Diabetes Mellitus. As for newborns, most infants had birth weight (43.6%) and correlation with gestational age (78.2%) compatible for good conditions of birth. Only (20.0%) of the infants had a difficult labor. It stood out although there was a slight predominance of severe asphyxia (50.9%) in the first minute and (45.5%) of the infants had record release intrauterine meconium. It was concluded that most mothers and newborns did not have risk factors for perinatal asphyxia, thus, this fact could be attributed to the structural conditions of service, especially in the care during labor, delivery and immediate assistance newborn.
