Effects of pregnancy experience on ovarian senescence and longevity in Hatano rats bred for high- and low-avoidance learning.
Effects of pregnancy experience on ovarian senescence and longevity in Hatano rats bred for high- and low-avoidance learning. Exp Gerontol. 2018 Dec 13;: Authors: Ohta R, Ohmukai H Abstract We investigated the effects of pregnancy experience on ovarian senescence and longevity using two inbred strains of Hatano rats. These strains have been selectively bred for high- and low-avoidance animals (HAA and LAA, respectively), but the HAA line has a slower onset of ovarian senescence and a shorter lifespan compared with the LAA line. The onset of abnormal estrous cycles and survival curves were compared between nulliparous and parous rats in each line. In the HAA line, pregnancy experience did not change the onset of ovarian senescence but increased longevity. This suggests that a pituitary tumor, which is a causal factor for accelerated mortality in this line, developed slowly in parous rats. In the LAA line, pregnancy experience delayed the onset of ovarian senescence and reduced the incidence of mammary tumors but did not increase longevity because of an increased frequency of constipation with megacolon. These data suggest that the effects of pregnancy experience on ovarian senescence and longevity depend on the reproductive characteristics of the rat strains.

This study explored the association between serum vitamin D levels and urinary tract infections in pregnant women.Study designIn this case control study, 187 participants including, 97 pregnant women diagnosed as a symptomatic UTI (case group) and 90 matched healthy pregnant women (control group) were consecutively enrolled from prenatal care clinic of Imam Reza Hospital in Urmia, North West of Iran. The two groups were matched for trimester and parity, and sexual intercourse. Blood samples were collected from both groups. Chemiluminescent immunoassay (CLIA) was used to evaluate the serum vitamin D levels. We used a binary...

In this issue of JAH, Choi et al.  report on research examining sexting among sexual minority youth. The results of their study represent a significantly more sophisticated understanding of this behavior, relative to the emergence of the concept of sexting approximately 15 years ago. Back then, in 2005, the Los Angeles Tim es published a news story referencing a phenomenon they called “sext messaging.” Three years later, a survey released by Cosmogirl.com and the National Campaign to Prevent Teen and Unplanned Pregnancy was the first to examine this behavior in a systematic way.

ConclusionsOverall health status is found to be poor among women during the perinatal period compared with the postpartum period. The study indicates that interventions to address the influencing factors are needed to ensure better quality of life for women both pre- and post-birth. Community-based initiatives, such as awareness building, might address negative factors and subsequently improve health status and reduce adverse health outcomes related to pregnancy and postnatal care.
This report aimed to discuss the reason for IVCT in a case of pregnancy-induced hypertension with decreased antithrombin III and protein S and the anticoagulation strategy.

TNF inhibitors still represent the first biologic after conventional synthetic DMARD (csDMARD) in the majority of patients according to registry data. This was p...
