The 2015 Brazilian Zika virus outbreak sparked a rapid response to control the spread of the virus. What was first understood to be a mild self-resolving infection is now linked to significant neurological defects in both neonates, and adults. The WHO declared the 2016 Zika epidemic a public health emergency and issued an unprecedented recommendation to women in affected regions to delay pregnancy until the risks surrounding Zika virus could be understood, or the epidemic contained. Since that time, considerable effort has been dedicated to understanding Zika transmission and pathogenesis to aid the development of drugs and vaccines...

STUDY QUESTION: Is resveratrol able to prevent the lipopolysaccharide (LPS)-induced preterm labor in 15-day pregnant BALB/c mice? SUMMARY ANSWER: Resveratrol prevented the LPS-induced onset of preterm labor in 64% of the cases and showed anti-inflammatory and tocolytic effects by downregulating COX-2 and iNOS expression and NOS activity, and by changing the uterine prostaglandin and endocannabinoid profiling. WHAT IS KNOWN ALREADY: Genital tract infections by Gram-negative bacteria are a common complication in human pregnancy and have been shown to increase risk of preterm delivery...

INTRODUCTION: Pregnancies in women with spinal cord injury (SCI) are at greater risk of morbidity and mortality. Although pregnancy after SCI is well elaborated in the literature, SCI occurring during pregnancy is rarely reported. Abrupt changes in the body physiology because of SCI and the resulting disability add a risk to maternal and fetal well-being. Not only is the burden of care increased but there is also a higher risk of developing pressure ulcers, urinary tract infections, autonomic instability, intrauterine growth retardation and venous thromboembolism...

Neospora caninum is an obligate parasite and a major cause of abortion in cattle. Pregnancy failures appear to be associated with weak innate defences on the maternal-fetal interface during infection with N. caninum. Herein, we studied the gene expression of Toll-like receptors (TLRs) in pregnant heifers immunized with different vaccine formulations against N. caninum before mating and then challenged the heifers with live N. caninum on day 70 of gestation. TLR7 and TLR8 expression was upregulated in the placental caruncle of infected-pregnant heifers previously exposed to live N...

BACKGROUND: To successfully develop and implement school-based sexual health interventions for adolescent girls, such as screening for Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis, it is important to understand parents' and teachers' attitudes towards sexual health education and acceptability of sexually transmitted infection (STI) screening interventions. METHODS: In this qualitative study, we approached parents and teachers from three high schools to participate in in-depth interviews (IDIs) and focus-group discussions (FGDs)...

Body piercing has evolved from a behavior once considered extreme to an accepted choice among the general population. Earlobe piercing is so common that it is now considered a normative behavior. The motivations for choosing body piercing have changed and are associated with piercing site and number of piercings chosen by the individual. Meanings ascribed to body piercing were traditionally related to enhanced sexual desirability and experience, but now range from the innocuous, such as a fashion statement, to the risk laden, such as nonsuicidal self-injury...

Zika virus (ZIKV) has been of major international public health concern following large outbreaks in the Americas occurring in 2015-2016. Most notably, ZIKV has been seen to pose dangers in pregnancy due to its association with congenital abnormalities such as microcephaly. Numerous experimental approaches have been taken to address how the virus can cross the placenta, alter normal fetal development, and disrupt specific cellular functions. Many areas concerning the mechanisms of transmission, especially from mother to fetus, are largely unknown but demand further research...

Dual method use, use of condoms plus another effective contraceptive method, is important in settings with high rates of unintended pregnancy and HIV infection. We evaluated the association of HIV status with dual method use in a cohort of postpartum women. Women completed baseline surveys in the postpartum ward and telephone surveys about contraceptive use 3, 6, and 12 months later. Nonpregnant women who completed at least one follow-up survey were eligible for this secondary analysis. Prevalence ratios were calculated using generalized estimating equations...

Pregnancy associated malaria (PAM) causes adverse pregnancy and birth outcomes owing to Plasmodium falciparum accumulation in the placenta. Placental accumulation is mediated by P. falciparum protein VAR2CSA, a leading PAM-specific vaccine target. The extent of its antigen diversity and impact on clinical outcomes remain poorly understood. Through amplicon deep-sequencing placental malaria samples from women in Malawi and Benin, we assessed sequence diversity of VAR2CSA's ID1-DBL2x region, containing putative vaccine targets and estimated associations of specific clades with adverse birth outcomes...

Venous thromboembolism (VTE) remains a leading cause of direct maternal deaths in the developed countries. The incidence of VTE has increased significantly during the past two decades. The absolute risk of VTE is estimated 0.6-2.2 per 1000 deliveries. Compared with age-matched non-pregnant women, the daily risk of VTE is increased 7- to 10-fold for antepartum VTE, but it is 15- to 35-fold for postpartum VTE. The incidence of pulmonary embolism (PE) during the first 6 weeks postpartum is nearly 15-fold higher compared to the incidence in pregnancy, and remains significantly increased up to 12 weeks postpartum...

There is a lack of evidence on the burden of Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Trichomonas vaginalis (TV) among HIV-infected pregnant women in South Africa. We conducted a cross-sectional analysis of HIV-infected pregnant women in two healthcare facilities in a South African township to determine the prevalence of CT, NG and TV. HIV-infected pregnant women were recruited during the first antenatal care visit for their current pregnancy and requested to self-collect vulvovaginal swab specimens...

Autism spectrum disorder (ASD) is phenotypically and etiologically heterogeneous, with evidence for genetic and environmental contributions to disease risk. Research has focused on the prenatal period as a time where environmental exposures are likely to influence risk for ASD. Epidemiological studies have shown significant associations between prenatal exposure to maternal immune activation (MIA), caused by infections and fever, and ASD. However, due to differences in study design and exposure measurements no consistent patterns have emerged revealing specific times or type of MIA exposure that are most important to ASD risk...

Classical treatment for congenital toxoplasmosis is based on combination of sulfadiazine and pyrimethamine plus folinic acid. Due to teratogenic effects and bone marrow suppression caused by pyrimethamine, the establishment of new therapeutic strategies is indispensable to minimize the side effects and improve the control of infection. Previous studies demonstrated that enrofloxacin and toltrazuril reduced the incidence of Neospora caninum and Toxoplasma gondii infection. The aim of the present study was to evaluate the efficacy of enrofloxacin and toltrazuril in the control of T...

ZIKA virus (ZIKV) poses a severe threat to the world. Recent outbreaks of ZIKV after 2007 along with its quick transmission have made this virus a matter of international concern. The virus shows symptoms that are similar to those caused in the wake of dengue virus (DENV) and other flaviviruses, which makes it difficult to discern the viral infection. Diagnosis is further complicated as the virus cross-reacts with antibodies of other viruses. Currently, molecular diagnosis of the virus is being performed by RT-PCR and IgM-captured enzyme-linked immunosorbent assay (MAC-ELISA)...

REVIEW
Joseph A McBride, Gregory M Gauthier, Bruce S Klein
The causal agents of blastomycosis, Blastomyces dermatitidis and Blastomyces gilchristii, belong to a group of thermally dimorphic fungi that can infect healthy and immunocompromised individuals. Following inhalation of mycelial fragments and spores into the lungs, Blastomyces spp convert into pathogenic yeast and evade host immune defenses to cause pneumonia and disseminated disease. The clinical spectrum of pulmonary blastomycosis is diverse. The diagnosis of blastomycosis requires a high degree of clinical suspicion and involves culture-based and non-culture-based fungal diagnostic tests...

On November 28, 2016, the Texas Department of State Health Services (Texas DSHS) reported its first confirmed case of local mosquitoborne Zika virus transmission in the city of Brownsville, located in south Texas along the U.S.-Mexico border. Zika virus infection during pregnancy has been linked to adverse congenital outcomes including microcephaly, neural tube defects, early brain malformations, structural eye abnormalities, congenital deafness, and limb contractures (1). On January 1, 2016, Texas DSHS established enhanced surveillance to identify women with laboratory evidence of possible Zika virus infection during pregnancy and suspected cases of Zika virus-associated birth defects among completed pregnancies...
