A survey of 17 countries found that 16.2% of US adults have used cocaine in their lifetime, with 42.4% using cannabis. The study suggests that drug use is not simply related to policy and that socioeconomic factors play a significant role.
A new study found that first-born children are more likely to develop asthma and allergy due to specific pregnancy conditions. Researchers investigated immune markers in cord blood IgE and skin prick tests at ages four and ten, revealing a statistically significant higher risk among first-borns.
Research at Yale University reveals a link between grhelin, the hunger hormone, and decreased fertility. Grhelin's impact on reproductive health is seen in mice bred with low ghrelin levels, producing smaller litter sizes and altered uterine development.
Researchers at Karolinska Institutet found that hysterectomy significantly increases the risk of urinary incontinence, with the highest likelihood noted within five years of the removal of the uterus. Women who had a hysterectomy before menopause or after multiple deliveries were particularly at risk.
Researchers are examining whether attempting to turn breech babies earlier in pregnancy increases success rate and reduces C-sections. A manual procedure called external cephalic version (ECV) is being tested on approximately 1,000 women from around the world.
A study of 4,000 pregnant women found that almost 1 in 5 overweight women required emergency Caesarean sections due to poor uterine contraction. Obese women experienced excessive bleeding following delivery, which was attributed to poor uterine activity.
A study found a strong connection between muscle damage during vaginal deliveries and pelvic organ prolapse, which causes the uterus, bladder, or bowel to fall down. The research suggests that preventing these injuries can help reduce the rate of pelvic organ prolapse.
Research published in Human Reproduction found that heavy smoking significantly lowers pregnancy rates among women who received donated oocytes, regardless of their own ovarian function. Heavy smokers had a lower chance of achieving pregnancy but higher multiple birth rates compared to non-heavy smokers.
A study found that biopsy procedures doubled a woman's chances of becoming pregnant during the next round of IVF. The researchers suggest that mild distress from the procedure may provoke a response making conditions in the uterus favorable for implantation.
The study reveals that the transcription factor protein C/EBPb is necessary for decidualization and successful pregnancy in mice. In humans, its presence may become a vital gene marker for predicting uterine readiness for implantation. This breakthrough could potentially alleviate shortcomings in in vitro fertilization.
Scientists at MIMR have identified adult stem cells in the uterus, which could lead to new treatments for conditions like pelvic floor prolapse. The discovery may also aid in understanding how diseases of the uterus develop and further general studies into adult stem cells.
A national study published in the New England Journal of Medicine found that vaginal birth after a cesarean section (VBAC) is more dangerous for mothers, with higher rates of uterine rupture and endometritis. However, the risk remains small, and researchers recommend thorough counseling for women considering VBAC.
A recent study published in the New England Journal of Medicine found that vaginal birth after a prior cesarean delivery poses relatively low risks. However, the study also revealed that women attempting vaginal birth after a cesarean delivery may face increased complications such as uterine rupture and infant brain oxygenation issues.
A systematic review found that diagnostic test accuracy is underestimated when results are verified after a delay, with an average underestimation of 74%.
Researchers at UT Southwestern Medical Center have found evidence of a substance secreted by the lungs of a developing fetus that contains the key signal to initiate labor. The study, led by Dr. Carole Mendelson, suggests a link between a specific fetal lung protein and labor in humans.
Researchers have successfully transplanted uteri into mice, paving the way for future womb transplants in humans. The study found that transplanted uteri can harbour pregnancies and rejection patterns are similar to other organs.
A recent study by Vanderbilt researchers found that high levels of estrogen can alter the expression of genes related to implantation in mice, leading to a reduced window of receptivity for embryo implantation. This could be contributing to high implantation failure rates in women undergoing IVF.
Scientists found that the embryo uses L-selectin on its surface to bind with carbohydrate molecules on the uterine wall, leading to a complete stop and attachment. This discovery may provide information useful for treating infertility and potentially offer insight into preeclampsia.
Researchers found that a molecular sticking process stops the embryo's journey along the uterine wall and starts attaching it to the wall, creating a sticky environment. The discovery of L-selectin protein helps to understand human embryo implantation and may prove useful to treat infertility.
Two new antiprogestin drugs show promise in reversible suppression of menstruation in rhesus macaque monkeys. The treatments block effects of estrogen on the uterus, preventing build-up of endometrial cells and potentially reducing symptoms of endometriosis. This could lead to relief for women suffering from distressing complaints.
Researchers found that mice lacking centromere protein B (CENP-B) suffer from reproductive failure due to defects in the uterus. The study suggests CENP-B plays a role in cell divisions that remodel the uterine lining during estrus and pregnancy.
A University of Michigan study analyzes data from various studies to show that whole-body metabolic rate changes over the course of the menstrual cycle, becoming about 7 percent lower after menstruation. This metabolic cycling saves an amount of energy equivalent to six days' worth of food over four menstrual cycles.
