#Benzophenone-3 promotion of mammary tumorigenesis is diet-dependent

Benzophenone-3 is a putative endocrine disrupting chemical and common ingredient in sunscreens. The potential of endocrine disrupting chemicals to act as agonists or antagonists in critical hormonally regulated processes, such as mammary gland development and mammary tumorigenesis, demands evaluation of its potential in promoting breast cancer. This study identifies the effects of BP-3 on mammary tumorigenesis with high-fat diet during puberty versus adulthood in Trp53-null … Continue reading #Benzophenone-3 promotion of mammary tumorigenesis is diet-dependent

RANK links #thymic regulatory T cells to fetal loss and gestational #diabetes in pregnancy

Successful pregnancies rely on adaptations within the mother1, including marked changes within the immune system2. It has long been known that the thymus, the central lymphoid organ, changes markedly during pregnancy3. However, the molecular basis and importance of this process remain largely obscure. Here we show that the osteoclast differentiation receptor RANK4,5 couples female sex hormones to the rewiring of the thymus during pregnancy. Genetic … Continue reading RANK links #thymic regulatory T cells to fetal loss and gestational #diabetes in pregnancy

#Menopause Transition and #Cardiovascular Disease Risk: Implications for Timing of Early Prevention: A Scientific Statement From the American Heart Association

Cardiovascular disease (CVD) is the leading cause of death in women, who have a notable increase in the risk for this disease after menopause and typically develop coronary heart disease several years later than men. This observation led to the hypothesis that the menopause transition (MT) contributes to the increase in coronary heart disease risk. Over the past 20 years, longitudinal studies of women traversing … Continue reading #Menopause Transition and #Cardiovascular Disease Risk: Implications for Timing of Early Prevention: A Scientific Statement From the American Heart Association

#Walking Volume and Speed Are Inversely Associated With Incidence of Treated #Hypertension in #Postmenopausal Women

Few studies have evaluated hypertension incidence in relation to walking, which is a common physical activity among adults. We examined the association between walking and hypertension incidence in 83 435 postmenopausal women who at baseline were aged 50 to 79 years, without known hypertension, heart failure, coronary heart disease, or stroke, and reported the ability to walk at least one block without assistance. Walking volume (metabolic … Continue reading #Walking Volume and Speed Are Inversely Associated With Incidence of Treated #Hypertension in #Postmenopausal Women

PAPPA-mediated adipose tissue remodeling mitigates insulin resistance and protects against #gestational #diabetes in mice and humans

Pregnancy is a physiological state of continuous adaptation to changing maternal and fetal nutritional needs, including a reduction of maternal insulin sensitivity allowing for appropriately enhanced glucose availability to the fetus. However, excessive insulin resistance in conjunction with insufficient insulin secretion results in gestational diabetes mellitus (GDM), greatly increasing the risk for pregnancy complications and predisposing both mothers and offspring to future metabolic disease. Here, … Continue reading PAPPA-mediated adipose tissue remodeling mitigates insulin resistance and protects against #gestational #diabetes in mice and humans

Nonsteroidal Anti-Inflammatory Drugs (#NSAIDs): Drug Safety Communication – Avoid Use of NSAIDs in #Pregnancy at 20 Weeks or Later

FDA is warning that use of NSAIDs around 20 weeks or later in pregnancy may cause rare but serious kidney problems in an unborn baby. This can lead to low levels of amniotic fluid surrounding the baby and possible complications. For prescription NSAIDs, FDA is requiring changes to the prescribing information to describe the risk of kidney problems in unborn babies that result in low … Continue reading Nonsteroidal Anti-Inflammatory Drugs (#NSAIDs): Drug Safety Communication – Avoid Use of NSAIDs in #Pregnancy at 20 Weeks or Later

Association Between #Epidural Analgesia During Labor and Risk of #Autism Spectrum Disorders in Offspring

Although the safety of labor epidural analgesia (LEA) for neonates has been well documented, the long-term health effects of LEA on offspring remain to be investigated… ..Among the cohort of 147 895 singleton children (74 425 boys [50.3%]; mean [SD] gestational age at delivery, 38.9 [1.5] weeks), 109 719 (74.2%) were exposed to maternal LEA. Fever during labor was observed in 13 055 mothers (11.9%) in the LEA group … Continue reading Association Between #Epidural Analgesia During Labor and Risk of #Autism Spectrum Disorders in Offspring

#HPV Vaccination and the Risk of Invasive #Cervical Cancer

The efficacy and effectiveness of the quadrivalent human papillomavirus (HPV) vaccine in preventing high-grade cervical lesions have been shown. However, data to inform the relationship between quadrivalent HPV vaccination and the subsequent risk of invasive cervical cancer are lacking.. ..During the study period, we evaluated girls and women for cervical cancer until their 31st birthday. Cervical cancer was diagnosed in 19 women who had received … Continue reading #HPV Vaccination and the Risk of Invasive #Cervical Cancer

#Aspirin use and risk of #breast cancer in African American women

Use of aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs) has been hypothesized to be associated with reduced risk of breast cancer; however, results of epidemiological studies have been mixed. Few studies have investigated these associations among African American women.. To assess the relation of aspirin use to risk of breast cancer in African American women, we conducted a prospective analysis within the Black Women’s Health … Continue reading #Aspirin use and risk of #breast cancer in African American women

#Obesity Has a Stronger Relationship with Colorectal #Cancer in Postmenopausal Women Than Premenopausal Women

Background: To examine the relationship between obesity measured by waist circumference (WC) and body mass index (BMI) and the incidence of colorectal cancer (CRC) in premenopausal and postmenopausal women. Methods: A total of 1,418,180 premenopausal and 4,854,187 postmenopausal women without cancer at baseline and aged over 40 were identified using the Korean National Health Insurance System Cohort during 2009-2014. The hazard ratio (HR) for CRC … Continue reading #Obesity Has a Stronger Relationship with Colorectal #Cancer in Postmenopausal Women Than Premenopausal Women

Association of #Menopausal Hormone Therapy With Breast #Cancer Incidence and Mortality During Long-term Follow-up of the Women’s Health Initiative Randomized Clinical Trials

In the trial involving 16 608 women with a uterus, 8506 were randomized to receive 0.625 mg/d of conjugated equine estrogen (CEE) plus 2.5 mg/d of medroxyprogesterone acetate (MPA) and 8102, placebo. In the trial involving 10 739 women with prior hysterectomy, 5310 were randomized to receive 0.625 mg/d of CEE alone and 5429, placebo. The CEE-plus-MPA trial was stopped in 2002 after 5.6 years’ median intervention … Continue reading Association of #Menopausal Hormone Therapy With Breast #Cancer Incidence and Mortality During Long-term Follow-up of the Women’s Health Initiative Randomized Clinical Trials

The Prevalence of Thyroid Dysfunction and Autoimmunity in Women With History of Miscarriage or Subfertility

..Thyroid function and thyroid peroxidase antibody (TPOAb) data were available for 19213 and 19237 women, respectively. The prevalence of abnormal thyroid function was 4.8% (95% CI, 4.5-5.1); euthyroidism was defined as levels of thyroid-stimulating hormone (TSH) of 0.44 to 4.50 mIU/L and free thyroxine (fT4) of 10 to 21 pmol/L. Overt hypothyroidism (TSH > 4.50 mIU/L, fT4 < 10 pmol/L) was present in 0.2% of … Continue reading The Prevalence of Thyroid Dysfunction and Autoimmunity in Women With History of Miscarriage or Subfertility
