The objective of this research was to determine the effect of disease misclassification on the estimated effect of metritis on milk production. Misclassification introduces bias that usually results in an underestimation of the association between exposure (disease) and the outcome of interest (milk production). This distorted measure of association results from the comparison of an affected population (some of which may not truly be affected) to a nonaffected population (which often includes affected subjects that are unidentified)...

The objective of the present review is to synthesize the information on the cellular and molecular players responsible for maintaining a homeostatic balance between a naturally invasive human placenta and the maternal uterus in pregnancy; to review the roles of decorin (DCN) as a molecular player in this homeostasis; to list the common maladies associated with a break-down in this homeostasis, resulting from a hypo-invasive or hyper-invasive placenta, and their underlying mechanisms. We show that both the fetal components of the placenta, represented primarily by the extravillous trophoblast, and the maternal component represented primarily by the decidual tissue and the endometrial arterioles, participate actively in this balance...

INTRODUCTION: Renal artery aneurysm rupture is an extremely rare cause of acute abdominal pain and haemodynamic instability in pregnancy. Due to its rarity, the diagnosis may not be immediately considered, and therefore there is a high associated mortality rate for both mother and fetus. PRESENTATION OF CASE: We present a case of a 41-year old primigravida who presented to the obstetricians at 22 weeks' gestation with severe abdominal pain, shock and fetal loss...

Despite the capacity of estrogens to favorably regulate body composition and glucose homeostasis, their use to combat obesity and type 2 diabetes is not feasible, because they promote sex steroid-responsive cancers. The novel selective estrogen receptor modulator (SERM) bazedoxifene acetate (BZA) uniquely antagonizes both breast cancer development and estrogen-related changes in the female reproductive tract. How BZA administered with conjugated estrogen (CE) or alone impacts metabolism is unknown. The effects of BZA or CE + BZA on body composition and glucose homeostasis were determined in ovariectomized female mice fed a Western diet for 10-12 wk...

The influence of seminal plasma on the cytokine and immune uterine environment is well characterised in mice and humans, while the effects of disruption to uterine seminal plasma exposure on pregnancy and offspring health is becoming more clearly understood. The cellular and molecular environment of the uterus during the pre- and peri-implantation period of early pregnancy is critical for implantation success and optimal foetal and placental development. Perturbations to this environment not only have consequences for the success of pregnancy and neonatal health and viability, but can also drive adverse health outcomes in the offspring after birth, particularly the development of metabolic disorders such as obesity, hypertension and insulin resistance...
