Alteration in vaginal microflora, douching prior to pregnancy, and preterm birth
We aimed to determine the relationship of douching prior to pregnancy and bacterial vaginosis (BV) during pregnancy on preterm birth, addressing individual and joint effects. We used a prospective cohort study and assessed vaginal microflora using gram stains and Nugent’s criteria. Douching behaviour was based on self-report about the 12 months prior to pregnancy. Preterm births were categorised as spontaneous or medically indicated. A total of 2561 women provided vaginal specimens and 1492 provided self-reports on douching behaviour
A Multicenter, Randomized Trial of Treatment for Mild Gestational Diabetes
It is uncertain whether treatment of mild gestational diabetes mellitus improves pregnancy outcomes
Hemodialysis Removes Uremic Toxins That Alter the Biological Actions of Endothelial Cells
Chronic kidney disease is linked to systemic inflammation and to an increased risk of ischemic heart disease and atherosclerosis. Endothelial dysfunction associates with hypertension and vascular disease in the presence of chronic kidney disease but the mechanisms that regulate the activation of the endothelium at the early stages of the disease, before systemic inflammation is established remain obscure. In the present study we investigated the effect of serum derived from patients with chronic kidney disease either before or after hemodialysis on the activation of human endothelial cells in vitro, as an attempt to define the overall effect of uremic toxins at the early stages of endothelial dysfunction. Our results argue that uremic toxins alter the biological actions of endothelial cells and the remodelling of the extracellular matrix before signs of systemic inflammatory responses are observed. This study further elucidates the early events of endothelial dysfunction during toxic uremia conditions allowing more complete understanding of the molecular events as well as their sequence during progressive renal failure
Molecular characterization and clinical relevance of metabolic expression subtypes in human cancers.
Metabolic reprogramming provides critical information for clinical oncology. Using molecular data of 9,125 patient samples from The Cancer Genome Atlas, we identified tumor subtypes in 33 cancer types based on mRNA expression patterns of seven major metabolic processes and assessed their clinical relevance. Our metabolic expression subtypes correlated extensively with clinical outcome: subtypes with upregulated carbohydrate, nucleotide, and vitamin/cofactor metabolism most consistently correlated with worse prognosis, whereas subtypes with upregulated lipid metabolism showed the opposite. Metabolic subtypes correlated with diverse somatic drivers but exhibited effects convergent on cancer hallmark pathways and were modulated by highly recurrent master regulators across cancer types. As a proof-of-concept example, we demonstrated that knockdown of SNAI1 or RUNX1—master regulators of carbohydrate metabolic subtypes-modulates metabolic activity and drug sensitivity. Our study provides a system-level view of metabolic heterogeneity within and across cancer types and identifies pathway cross-talk, suggesting related prognostic, therapeutic, and predictive utility

What Started Your Labor? Responses From Mothers in the Third Pregnancy, Infection, and Nutrition Study
Many behaviors and substances have been purported to induce labor. Using data from the Third Pregnancy,
Infection, and Nutrition cohort, we focus on 663 women who experienced spontaneous labor. Of
the women who reported a specific labor trigger, 32% reported physical activity (usually walking), 24% a
clinician-mediated trigger, 19% a natural phenomenon, 14% some other physical trigger (including sexual
activity), 12% reported ingesting something, 12% an emotional trigger, and 7% maternal illness. With the
exceptions of walking and sexual intercourse, few women reported any one specific trigger, although various
foods/substances were listed in the “ingesting something” category. Discussion of potential risks associated
with “old wives’ tale” ways to induce labor may be warranted as women approach term.Keywords: trigger, obstetric, labor, birt
Delivery timing and Cesarean delivery risk in women with mild gestational diabetes
To evaluate the relationship between gestational age (GA) and induction of labor (IOL) and the rate of cesarean delivery (CD) in women with mild gestational diabetes (GDM)
Advanced lipoprotein measures and recurrent preterm birth
Lipoproteins are associated with atherogenic and inflammatory processes, and these processes may be related to adverse pregnancy outcomes. We therefore examined whether variations in lipoprotein particle size and concentration are associated with preterm birth (PTB) < 35 weeks’ gestation
Can differences in obstetric outcomes be explained by differences in the care provided? The MFMU Network APEX study
To determine whether hospital differences in the frequency of adverse obstetric outcomes are related to differences in care
