Prenatal exposure to phenols, phthalates (PAEs), and organophosphate (OP) pesticides may increase the risk of abnormal birth outcomes. However, many previous studies have examined exposure to a limited number of chemical classes or exposure profiles limited to a specific stage of pregnancy. This study aims to characterize the concurrent exposure scenario throughout pregnancy by simultaneously monitoring internal doses of several endocrine-disrupting compounds (EDCs), including 2 phenols (nonylphenol (NP) and bisphenol A (BPA)), 9 PAEs, and 6 OP pesticide metabolites and to assess the relationships between concurrent exposure to EDCs and infant birth weight, length, and head and chest circumference...

Interleukin (IL)-12 is composed of p35 and p40 subunit, in this case IL-12p40 deficiency is a rare genetic etiology of Mendelian susceptibility to mycobacterial disease (MSMD). Salmonellosis has been reported in almost half of these patients and mostly present in recurrent extra intestinal form. In this report, we described an 18 month old boy with absence of IL12p40 production suffering from chronic disseminated non-typhoidal salmonellosis. To the best of our knowledge this is the first reported case.

Published data on the association between 8q24 rs6983267 polymorphism and cancer risk are inconsistent. Thus, we conducted a meta-analysis to evaluate the relationship between rs6983267 polymorphism and cancer risk. We searched on PubMed, EMBASE, Web of Science and China National Knowledge Infrastructure (CNKI) up to November 1, 2016 for relevant studies. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to estimate the strength of this association. We included 78 case-control studies with a total of 73,996 cases and 96,741 controls in this meta-analysis...

The benefits of breastfeeding over formula feed are widely appreciated. However, for many mothers breastfeeding is not possible, highlighting the need for a significant improvement in the contents of formula feed. In this article, the overlooked role of melatonin and the melatonergic pathways in breast milk and in the regulation of wider breast milk components are reviewed. There is a growing appreciation that the benefits of breastfeeding are mediated by its effects in the infant gut, with consequences for the development of the gut-brain axis and the immune system...

Fatemeh Fattahi, Peter A Ward
Following a severe primary infection or trauma, the risk of developing pneumonia increases due to acquired immune defects collectively known as sepsis-induced immunosuppression. In this issue of Immunity, Roquilly et al. (2017) show that dendritic cells and macrophages developing in the lung after the resolution of a severe infection acquire tolerogenic properties that contribute to persistent immunosuppression and susceptibility to secondary infections.

Lung infections cause prolonged immune alterations and elevated susceptibility to secondary pneumonia. We found that, after resolution of primary viral or bacterial pneumonia, dendritic cells (DC), and macrophages exhibited poor antigen-presentation capacity and secretion of immunogenic cytokines. Development of these "paralyzed" DCs and macrophages depended on the immunosuppressive microenvironment established upon resolution of primary infection, which involved regulatory T (Treg) cells and the cytokine TGF-β...

In the course of a systematic screen of plant transcriptomic data, the sequence of a novel viroid-like RNA was identified in four contigs in a recent Transcriptome Shotgun Assembly (TSA) from lychee in China. Portions of this sequence are closely related to the central conserved region (CCR) and terminal conserved region (TCR) present in members of the genus Apscaviroid, sequences that are important criteria for viroid classification. RT-PCR with two divergent adjacent primers amplified the full 304 nucleotide sequence of this viroid-like RNA which can be folded into the rod-like secondary structure that is a typical feature of viroids in the family Pospiviroidae...

As the applications and environmental release of silver ions and nanoparticles are increasing, growing human exposures to these pollutants have become an emerging health concerns. The impeding effects of such pollutants on susceptible populations are severely under-studied. Here, we demonstrate that Ag NPs, at a dose that causes no general toxicity in normal mice, promote the progression of fatty liver disease from steatosis to steatohepatitis only in overweight mice. Exposure to Ag+ ions induces the same effects in overweight mice...

West Nile virus is primarily maintained cryptically primarily in avian (Passerine) populations where it is transmitted by Culex spp. mosquitoes. Mosquito control measures currently include physical activities to reduce mosquito breeding sites, the application of mosquito larvicides, or aerosolized insecticides to kill adults (adulticides) when arboviral diseases such as West Nile virus (WNV) or Zika virus are detected in mosquito populations. Organochlorine, organohosphorus, carbamate and pyrethroid insecticides are often used...

The study of the intestinal microbiota has begun to shift from cataloging individual members of the commensal community to understanding their contributions to the physiology of the host organism in health and disease. Here, we review the effects of the microbiome on innate and adaptive immunological players from epithelial cells and antigen-presenting cells to innate lymphoid cells and regulatory T cells. We discuss recent studies that have identified diverse microbiota-derived bioactive molecules and their effects on inflammation within the intestine and distally at sites as anatomically remote as the brain...

BACKGROUND: The onset of inflammatory bowel disease (IBD) during childhood/adolescence compromises peak bone mass acquisition and predisposes to fractures later in life. However, the structural basis for bone fragility in young adults with IBD remains unknown. METHODS: One hundred two young subjects from the Swiss IBD cohort were included. Areal bone mineral density (aBMD) at distal radius, hip, and spine as well as morphometric vertebral fractures were assessed using dual-energy x-ray absorptiometry technique...

Upon thermal annealing at or above room temperature (RT) and at high hydrostatic pressure <i>P</i> ~ 155 GPa, sulfur trihydride H<sub>3</sub>S exhibits a measured maximum superconducting transition temperature <i>T</i><sub>C</sub> ~ 200 K. Various theoretical frameworks incorporating strong electron-phonon coupling and Coulomb repulsion have reproduced this record-level <i>T</i><sub>C</sub>. Of particular relevance is that experimentally observed H-D isotopic correlations among <i>T</i><sub>C</sub>, <i>P</i>, and annealed order indicate an H-D isotope effect exponent α limited to values ≤ 0...

Mass administration of azithromycin (MDA) is integral to trachoma control. Recent studies suggest that MDA may increase drug-resistant pathogens, yet findings from prior studies suggest little long-term impact on resistance. This disparity may be linked to differences in pre-MDA community-level resistance patterns. We describe carriage prevalence and antibiotic resistance patterns for Streptococcus pneumoniae (Spn) (nasopharyngeal swab collection), Staphylococcus aureus (SA) (nasopharyngeal swabs), and Escherichia coli (EC) (rectal swabs) in 1,047 children ages 1-59 months in a district with MDA cessation 4 years ago...

Marine microorganisms such as Shewanella spp., Vibrio spp., and Aeromonas spp. can cause sepsis secondary to a wound infection in the context of swimming. These microorganisms are most often susceptible to fluoroquinolones. Here, we report a unique case of Shewanella algae bacteremia associated with meningoencephalitis and disseminated via hematogenous spread secondary to a skin injury. The patient suffered the injury while swimming in saline water during a cruise holiday in Madagascar, and she was initially treated with amoxicillin...
