How does weight gain since the age of 18 years affect breast cancer risk in later life? A meta-analysis.

Early life factors are important risk factors for breast cancer. The association between weight gain after age 18 and breast cancer risk is inconsistent across previous epidemiologic studies. To evaluate this association, we conducted a meta-analysis according to PRISMA guidelines and the established inclusion criteria. We performed a comprehensive literature search using Medline (Ovid), Embase, Scopus, Cochrane Library, and ClinicalTrials.gov to identify relevant studies published before June 3, 2022. Two reviewers independently reviewed the articles for final inclusion. Seventeen out of 4,725 unique studies met the selection criteria. The quality of studies was assessed using the Newcastle-Ottawa Scale (NOS), and all were of moderate to high quality with NOS scores ranging from 5 to 8. We included 17 studies (11 case-control, 6 cohort) in final analysis. In case-control studies, weight gain after age 18 was associated with an increased risk of breast cancer (odds ratio [OR] = 1.25; 95% CI = 1.07-1.48), when comparing the highest versus the lowest categories of weight gain. Menopausal status was a source of heterogeneity, with weight gain after age 18 associated with an increased risk of breast cancer in postmenopausal women (OR = 1.53; 95% CI = 1.40-1.68), but not in premenopausal women (OR = 1.01; 95% CI = 0.92-1.12). Additionally, a 5 kg increase in weight was positively associated with postmenopausal breast cancer risk (OR = 1.12; 95%CI = 1.05-1.21) in case-control studies. Findings from cohort studies were identical, with a positive association between weight gain after age 18 and breast cancer incidence in postmenopausal women (relative risk [RR] = 1.30; 95% CI = 1.09-1.36), but not in premenopausal women (RR = 1.06; 95% CI = 0.92-1.22). Weight gain after age 18 is a risk factor for postmenopausal breast cancer, highlighting the importance of weight control from early adulthood to reduce the incidence of postmenopausal breast cancer.

Clinical factors associated with patterns of endocrine therapy adherence in premenopausal breast cancer patients.

INTRODUCTION: Patients with hormone receptor positive breast cancer are recommended at least five years of adjuvant endocrine therapy, but adherence to this treatment is often suboptimal. We investigated longitudinal trends in adjuvant endocrine therapy (AET) adherence among premenopausal breast cancer patients and identified clinical characteristics, including baseline comorbidities and non-cancer chronic medication use, associated with AET adherence. METHODS: We included stage I-III premenopausal breast cancer patients diagnosed during 2002-2011 and registered in the Danish Breast Cancer Group clinical database who initiated AET. We used group-based trajectory modeling to describe AET adherence patterns. We also linked patients to Danish population-based registries and fit multinomial logistic models to compute odds ratios (ORs) and 95% confidence intervals (95% CIs) associating clinical characteristics with AET adherence patterns. RESULTS: We identified three adherence patterns among 4,353 women-high adherers (57%), slow decliners (36%), and rapid decliners (6.9%). Women with stage I disease (vs. stage II; OR: 1.9, 95% CI 1.5, 2.5), without chemotherapy (vs. chemotherapy; OR: 4.3, 95% CI 3.0, 6.1), with prevalent comorbid disease (Charlson Comorbidity Index score ≥ 1 vs. 0; OR: 1.6, 95% CI 1.1, 2.3), and with a history of chronic non-cancer medication use (vs. none; OR: 1.3, 95% CI 1.0, 1.8) were more likely to be rapid decliners compared with high adherers. CONCLUSIONS: Women with stage I cancer, no chemotherapy, higher comorbidity burden, and history of chronic non-cancer medication use were less likely to adhere to AET. Taking steps to promote adherence in these groups of women may reduce their risk of recurrence.

21-gene expression assay and clinical outcomes of premenopausal patients with hormone receptor-positive breast cancer.

The prognostic role of the recurrence score (RS) based on the 21-gene expression assay in premenopausal women is not well delineated, and we investigated the association of outcomes and the RS in premenopausal patients who had 21-gene expression assay at Asan Medical Center, Seoul, Korea, between June 2005 and July 2018. Invasive breast cancer-free survival (IBCFS) by STEEP version 2.0 was compared according to the RS and clinical risk factors. A total of 554 patients were included in our study and 116 patients (20.9%) had age <40 years, 238 patients (43.0%) had luminal B subtype (Ki67 ≥ 20%), and 83 patients (15.0%) had RS >25. All patients received adjuvant tamoxifen ± chemotherapy. Overall, patients with RS >25 showed trend toward worse IBCFS from multivariable analysis (adjusted HR 1.89 [95% CI: 0.95-3.73], P = .069). When comparing outcomes according to age and luminal subtypes, patients with luminal B subtype and age <40 years (n = 60) showed significantly worse outcomes compared to the others (luminal A or luminal B + age ≥40 years, n = 494; adjusted HR 2.95 [95% CI: 1.49-5.82], log-rank P < .001). Among patients with luminal B subtype and age <40 years, there was no significant association observed between IBCFS and the RS (log-rank P = .51). In conclusion, while RS >25 showed association with poor outcomes in premenopausal women, it may have less prognostic significance among those with luminal B subtype and age <40 years.

Lifetime alcohol consumption patterns and young-onset breast cancer by subtype among Non-Hispanic Black and White women in the Young Women's Health History Study.

PURPOSE: The role of alcohol in young-onset breast cancer (YOBC) is unclear. We examined associations between lifetime alcohol consumption and YOBC in the Young Women's Health History Study, a population-based case-control study of breast cancer among Non-Hispanic Black and White women < 50 years of age. METHODS: Breast cancer cases (n = 1,812) were diagnosed in the Metropolitan Detroit and Los Angeles County SEER registry areas, 2010-2015. Controls (n = 1,381) were identified through area-based sampling and were frequency-matched to cases by age, site, and race. Alcohol consumption and covariates were collected from in-person interviews. Weighted multivariable logistic regression was conducted to calculate adjusted odds ratios (aOR) and 95% confidence intervals (CI) for associations between alcohol consumption and YOBC overall and by subtype (Luminal A, Luminal B, HER2, or triple negative). RESULTS: Lifetime alcohol consumption was not associated with YOBC overall or with subtypes (all ptrend ≥ 0.13). Similarly, alcohol consumption in adolescence, young and middle adulthood was not associated with YOBC (all ptrend ≥ 0.09). An inverse association with triple-negative YOBC, however, was observed for younger age at alcohol use initiation (< 18 years vs. no consumption), aOR (95% CI) = 0.62 (0.42, 0.93). No evidence of statistical interaction by race or household poverty was observed. CONCLUSIONS: Our findings suggest alcohol consumption has a different association with YOBC than postmenopausal breast cancer-lifetime consumption was not linked to increased risk and younger age at alcohol use initiation was associated with a decreased risk of triple-negative YOBC. Future studies on alcohol consumption in YOBC subtypes are warranted.

Multidrug resistance among uropathogenic clonal group A E. Coli isolates from Pakistani women with uncomplicated urinary tract infections.

OBJECTIVE: Multi-drug resistance (MDR) has notably increased in community acquired uropathogens causing urinary tract infections (UTIs), predominantly Escherichia coli. Uropathogenic E. coli causes 80% of uncomplicated community acquired UTIs, particularly in pre-menopausal women. Considering this high prevalence and the potential to spread antimicrobial resistant genes, the current study was conducted to investigate the presence of clinically important strains of E. coli in Pakistani women having uncomplicated cystitis and pyelonephritis. Women belonging to low-income groups were exclusively included in the study. Seventy-four isolates from urine samples were processed, phylotyped, and screened for the presence of two Single Nucleotide Polymorphisms (SNPs) particularly associated with a clinically important clonal group A of E. coli (CgA) followed by antibiotic susceptibility testing and genome sequence analysis. RESULTS: Phylogroup B2 was most prevalent in patients and 44% of isolates were positive for the presence of CgA specific SNPs in Fumarate hydratase and DNA gyrase subunit B genes. Antibiotic susceptibility testing showed widespread resistance to trimethoprim-sulfamethoxazole and extended-spectrum beta-lactamase production. The infection analysis revealed the phylogroup B2 to be more pathogenic as compared to the other groups. The genome sequence of E. coli strain U17 revealed genes encoding virulence, multidrug resistance, and host colonization mechanisms. CONCLUSIONS: Our research findings not only validate the significant occurrence of multidrug-resistant clonal group A E. coli (CgA) in premenopausal Pakistani women suffering from cystitis and pyelonephritis but also reveal the presence of genes associated withvirulence, and drug efflux pumps. The detection of highly pathogenic, antimicrobial-resistant phylogroup B2 and CgA E. coli strains is likely to help in understanding the epidemiology of the pathogen and may ultimately help to reduce the impact of these strains on human health. Furthermore, the findings of this study will particularly help to reduce the prevalence of uncomplicated UTIs and the cost associated with their treatment in women belonging to low-income groups.

Evaluation of some proinflammatory cytokines and biochemical parameters in pre and postmenopausal breast cancer women.

The study was planned to evaluate the differences in certain proinflammatory cytokines(IL-6, TNF-α) with CRP and biochemical parameters (E2, D3, LDH, GGT, TSB, Ca, Ph, uric acid), between women with pre- and postmenopausal breast cancer and seemingly healthy women in Iraqi women as controls; at medical city in teaching Oncology hospital,70 breast cancer patients women their ages ranged (47.51 ± 1.18) and 20 healthy women with age (44.45 ± 2.66) begun from September (2020) to February (2021). The aims of this study to investigate the evaluation of chemotherapy effects especially doxorubicin and cyclophosphamide only use in this study in pre and postmenopausal breast cancer women on proinflammatory cytokines(IL-6, TNF-α) with CRP and on biochemical parameters(E2, D3, LDH, GGT, TSB, Ca, Ph, uric acid) in pre and postmenapausal breast cancer women. The patients were divided into five groups and each group contains 14 patients women with breast cancer during pre and postmenopausal periods. The control groups were divided into 10 pre and 10 postmenopausal women(Fig. 1). The results of proinflammatory cytokines of and biochemical parameters in premenopausal groups were as the levels of IL-6 (pg/ml),TNF-α(pg/ml) and CRP (ng/ml) showed significant increase differences (P < 0.01)among breast cancer treated (BCT) groups in comparison with control groups,While the Liver enzymes GGT,LDH and TSB showed highly significant increase (P < 0.01) in BCT groups, Estrogen levels (pg/ml) and D3(ng/ml) increased significantly (P < 0.01)among BCT groups. Blood serum calcium and phosphorus with uric acid levels (mg/dl) showed significant difference (P < 0.01); While the result in postmenopausal of IL-6(pg/ml), TNF-α (pg/ml) and CRP (ng/ml) showed highly significant differences (P < 0.01)among BCT groups.While GGT(IU/L), LDH(IU/L) and TSB (mg/dl) enzymes were increased significantly (p < 0.01), Estrogen (pg/ml) and D3(ng/ml) levels showed significant increase (P < 0.01) among BCT groups.Blood calcium and phosphorus showed significant increase (P < 0.01) while uric acid was non-significant increase (P > 0.05).

Relugolix combination therapy in Black/African American women with symptomatic uterine fibroids: LIBERTY Long-Term Extension study.

BACKGROUND: In the LIBERTY Long-Term Extension study, once-daily relugolix combination therapy (40 mg relugolix, estradiol 1 mg, norethindrone acetate 0.5 mg) substantially improved uterine fibroid-associated heavy menstrual bleeding throughout the 52-week treatment period in the overall study population. OBJECTIVE: Black or African American women typically experience a greater extent of disease and symptom burden of uterine fibroids vs other racial groups and have traditionally been underrepresented in clinical trials. This secondary analysis aimed to assess the efficacy and safety of relugolix combination therapy in the subgroup population of Black or African American women with uterine fibroids in the LIBERTY Long-Term Extension study. STUDY DESIGN: Black or African American premenopausal women (aged 18-50 years) with uterine fibroids and heavy menstrual bleeding who completed the 24-week randomized, placebo-controlled, double-blind LIBERTY 1 (identifier: NCT03049735) or LIBERTY 2 (identifier: NCT03103087) trials were eligible to enroll in the 28-week LIBERTY Long-Term Extension study (identifier: NCT03412890), in which all women received once-daily, open-label relugolix combination therapy. The primary endpoint of this subanalysis was the proportion of Black or African American treatment responders: women who achieved a menstrual blood loss volume of <80 mL and at least a 50% reduction in menstrual blood loss volume from the pivotal study baseline to the last 35 days of treatment by pivotal study randomized treatment group. The secondary outcomes included rates of amenorrhea and changes in symptom burden and quality of life. RESULTS: Overall, 241 of 477 women (50.5%) enrolled in the LIBERTY Long-Term Extension study self-identified as Black or African American. In Black or African American women receiving continuous relugolix combination therapy for up to 52 weeks, 58 of 70 women (82.9%; 95% confidence interval, 72.0%-90.8%) met the treatment responder criteria for reduction in heavy menstrual bleeding (primary endpoint). A substantial reduction in menstrual blood loss volume from the pivotal study baseline to week 52 was demonstrated (least squares mean percentage change: 85.0%); 64.3% of women achieved amenorrhea; 59.1% of women with anemia at the pivotal study baseline achieved a substantial improvement (>2 g/dL) in hemoglobin levels; and decreased symptom severity and distress because of uterine fibroid-associated symptoms and improvements in health-related quality of life through 52 weeks were demonstrated. The most frequently reported adverse events during the cumulative 52-week treatment period were hot flush (12.9%), headache (5.7%), and hypertension (5.7%). Bone mineral density was preserved through 52 weeks. CONCLUSION: Once-daily relugolix combination therapy improved uterine fibroid-associated heavy menstrual bleeding in most Black or African American women who participated in the LIBERTY Long-Term Extension study. The safety and efficacy profile of relugolix combination therapy in Black or African American women was consistent with previously published results from the overall study population through 52 weeks. Findings from this subanalysis will assist shared decision-making by helping providers and Black or African American women understand the efficacy and safety of relugolix combination therapy as a pharmacologic option for the management of uterine fibroid-associated symptoms.

Obesity and adverse breast cancer risk and outcome: Mechanistic insights and strategies for intervention.

Answer questions and earn CME/CNE Recent decades have seen an unprecedented rise in obesity, and the health impact thereof is increasingly evident. In 2014, worldwide, more than 1.9 billion adults were overweight (body mass index [BMI], 25-29.9 kg/m2 ), and of these, over 600 million were obese (BMI ≥30 kg/m2 ). Although the association between obesity and the risk of diabetes and coronary artery disease is widely known, the impact of obesity on cancer incidence, morbidity, and mortality is not fully appreciated. Obesity is associated both with a higher risk of developing breast cancer, particularly in postmenopausal women, and with worse disease outcome for women of all ages. The first part of this review summarizes the relationships between obesity and breast cancer development and outcomes in premenopausal and postmenopausal women and in those with hormone receptor-positive and -negative disease. The second part of this review addresses hypothesized molecular mechanistic insights that may underlie the effects of obesity to increase local and circulating proinflammatory cytokines, promote tumor angiogenesis and stimulate the most malignant cancer stem cell population to drive cancer growth, invasion, and metastasis. Finally, a review of observational studies demonstrates that increased physical activity is associated with lower breast cancer risk and better outcomes. The effects of recent lifestyle interventions to decrease sex steroids, insulin/insulin-like growth factor-1 pathway activation, and inflammatory biomarkers associated with worse breast cancer outcomes in obesity also are discussed. Although many observational studies indicate that exercise with weight loss is associated with improved breast cancer outcome, further prospective studies are needed to determine whether weight reduction will lead to improved patient outcomes. It is hoped that several ongoing lifestyle intervention trials, which are reviewed herein, will support the systematic incorporation of weight loss intervention strategies into care for patients with breast cancer.

Pharmacotherapy of Hypoactive Sexual Desire Disorder in Premenopausal Women.

OBJECTIVE: This review aims to provide an overview of pharmacologic management for hypoactive sexual desire disorder (HSDD) in premenopausal women, with a focus on available agents. DATA SOURCES: Through a literature search on PubMed, Google Scholar, and ClinicalTrials.gov from 1999 to 2024, studies were selected using the following MeSH search terms: hypoactive sexual desire disorder, premenopause, pharmacologic management, flibanserin, bremelanotide, buspirone, bupropion, and testosterone, excluding those involving postmenopausal women or other sexual disorders. Product monographs were also reviewed. STUDY SELECTION AND DATA EXTRACTION: Relevant English-language studies or those conducted in humans were considered. DATA SYNTHESIS: Hypoactive sexual desire disorder, characterized by a lack of motivation for sexual activity, predominantly affects women aged 45 years and older. Treatment involves a multimodal approach, including nonpharmacologic interventions such as psychotherapy and lifestyle adjustments, alongside pharmacologic options. Although bupropion and buspirone may be considered off-label treatments, flibanserin and bremelanotide are the sole medications approved by the Food and Drug Administration for generalized acquired HSDD in premenopausal women. However, caution is advised due to their limited efficacy, potential adverse effects, and transparency issues in reporting. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE: Hypoactive sexual desire disorder, while not life-threatening, significantly impacts well-being and relationships. Pharmacotherapy, including options like flibanserin and bremelanotide, is essential within a multidisciplinary approach. Validated tools and objective measures inform tailored premenopausal HSDD care plans and aid in striking a balance between potential risks and adverse effects while maximizing meaningful clinical benefits, including for transgender individuals. CONCLUSIONS: Clinicians must discern important distinctions between flibanserin, bremelanotide, and other agents when managing premenopausal HSDD. Further research with the most suitable clinical endpoints and consideration of patient factors are crucial before widespread adoption of flibanserin and bremelanotide. Pharmacists are encouraged to embrace this opportunity to provide premenopausal HSDD care in ambulatory and community practice settings.

Ovarian Suppression: Early Menopause, Late Effects.

PURPOSE OF REVIEW: Pre-menopausal women diagnosed with hormone receptor (HR) breast cancer are candidates for prolonged hypoestrogenism to improve cancer outcomes. However, the disease benefit eclipses the toxicities associated with ovarian function suppression (OFS), which are often under-reported. RECENT FINDINGS: Increased risk of mortality from cardiovascular disease, bone disorders, and metabolic disorders is well reported in women with no history of cancer, after surgical oophorectomy or premature ovarian failure. Vasomotor symptoms, urogenital atrophy, weight gain, sexual dysfunction, cognitive decline, and sleep disturbances contribute to the increased non-compliance associated with OFS, especially in younger women. Balancing the toxicities of prolonged OFS with its benefits should be critically analyzed by providers when making recommendations for their patients. Supportive care to manage multi-system toxicities and to counteract the long-term impact on all-cause mortality should be emphasized by every cancer program. Future studies with OFS should incorporate patient outcomes and strategies for symptom management in addition to focusing on improving disease outcomes.

Pelvic floor symptoms among premenopausal women with pelvic organ prolapse in the Democratic Republic of the Congo.

INTRODUCTION AND HYPOTHESIS: Most of the literature on pelvic organ prolapse (POP) has been generated from postmenopausal patients in high-income countries. In the Democratic Republic of the Congo (DRC), a significant proportion of patients who present for surgical management of POP are premenopausal. Little is known about the impact of POP on pelvic floor symptoms in this population. The objective was to describe pelvic floor symptoms and sexual function among premenopausal patients presenting for POP surgery in DRC. METHODS: We performed a prospective cohort study of symptomatic premenopausal patients undergoing fertility-sparing POP surgery at a large referral hospital in the DRC. Pelvic floor symptoms were evaluated with the Pelvic Floor Distress Inventory Questionnaire and sexual function with the Pelvic organ prolapse/urinary Incontinence Sexual Questionnaire. Data are presented as means with standard deviations or counts with percentages. RESULTS: A total of 107 patients were recruited between April 2019 and December 2021. All had either stage III (95.3%) or stage IV (4.7%) prolapse. Ages were 34.2 ± 6.7 years; 78.5% were married. A majority of patients experienced low abdominal pain (82.2%), heaviness or dullness (95.3%), and bulging or protrusion of the prolapse (92.5%). Almost two-thirds of patients reported no longer being sexually active, and 80% stated that they were not sexually active because of POP. Of the 37 sexually active patients (34.6%), nearly all reported significant sexual impairment because of the prolapse, with only 4 reporting no sexual impairment. CONCLUSIONS: This study represents one of the largest prospective series of patients with premenopausal POP. Our results highlight the severity of pelvic floor symptoms and the negative effects on sexual function among this patient population with POP.

Pregnancy and lactation-associated osteoporosis as a major type of premenopausal osteoporosis: a retrospective cohort study based on real-world data.

BACKGROUND: Pregnancy and lactation-associated osteoporosis (PLO), as well as premenopausal osteoporosis, might be a predictor of future fracture. This study aimed to describe the clinical features of PLO as a subtype of premenopausal osteoporosis and to evaluate medical interventions for it. METHODS: From an administrative claims database including 4,224,246 people in Japan, we classified women for whom the date of childbirth had been defined and who had suffered low-trauma fracture between the ages of 18-47 years as the premenopausal osteoporosis group. A fracture site for which the odds ratio for fractures occurring between 5 months before and 12 months after childbirth (around childbirth) was greater than 1 was considered the PLO site. We classified patients with a fracture at the PLO site around childbirth as the PLO group. The control group consisted of 500 women without fragility fractures. We investigated some drugs and diseases to explore fracture-causing factors, as well as medical interventions such as osteoporosis diagnosis, bone densitometry, anti-osteoporosis pharmacotherapy, and lactation inhibitors. RESULTS: In total, 231 parous women were classified into the premenopausal osteoporosis group. The most common fracture was vertebral fracture and was likely to occur around childbirth, followed by distal radius and sacral fractures, which were rare around childbirth. Considering vertebral, pelvic, and proximal femoral fractures as PLO sites, 56 women with 57 PLO fractures were classified into the PLO group. The incidence of PLO was estimated at 460 per million deliveries. Ovulation disorder and high maternal age were associated with the development of PLO. Vertebral fracture was the most common PLO fracture. It was mainly diagnosed a few months, and possibly up to 1 year, postpartum. PLO patients with vertebral fractures underwent more medical interventions than did those with other fractures, but they were still inadequate. CONCLUSIONS: PLO with vertebral fracture was one of the major types of premenopausal osteoporosis. The prevalence of PLO is considered to be higher than previously thought, indicating the presence of potentially overlooked patients. More timely interventions for PLO might lead to the improved management of latent patients with premenopausal osteoporosis and reduce future fracture risk.

Antipsychotic-induced prolactin elevation in premenopausal women with schizophrenia: associations with estrogen, disease severity and cognition.

PURPOSE: Antipsychotic-induced prolactin elevation may impede protective effects of estrogens in women with schizophrenia-spectrum disorders (SSD). Our study sought to confirm whether the use of prolactin-raising antipsychotics is associated with lower estrogen levels, and to investigate how estrogen and prolactin levels relate to symptom severity and cognition in premenopausal women with SSD. METHODS: This cross-sectional study included 79 premenopausal women, divided in three groups of women with SSD treated with prolactin-sparing antipsychotics (n = 21) or prolactin-raising antipsychotics (n = 27), and age-matched women without SSD (n = 31). Circulating 17ß-estradiol was compared among groups. In patients, we assessed the relationship between prolactin and 17ß-estradiol, and the relationships of these hormones to symptom severity and cognition, using correlation analyses and backward regression models. RESULTS: In women receiving prolactin-raising antipsychotics, 17ß-estradiol levels were lower as compared to both other groups (H(2) = 8.34; p = 0.015), and prolactin was inversely correlated with 17ß-estradiol (r=-0.42, p = 0.030). In the prolactin-raising group, 17ß-estradiol correlated positively with verbal fluency (r = 0.52, p = 0.009), and 17ß-estradiol and prolactin together explained 29% of the variation in processing speed (ß17ß-estradiol = 0.24, ßprolactin = -0.45, F(2,25) = 5.98, p = 0.008). In the prolactin-sparing group, 17ß-estradiol correlated negatively with depression/anxiety (r = -0.57, p = 0.014), and together with prolactin explained 26% of the variation in total symptoms (ß17ß-estradiol = -0.41, ßprolactin = 0.32, F(2,18) = 4.44, p = 0.027). CONCLUSIONS: In women with SSD, antipsychotic-induced prolactin elevation was related to lower estrogen levels. Further, estrogens negatively correlated with symptom severity and positively with cognition, whereas prolactin levels correlated negatively with cognition. Our findings stress the clinical importance of maintaining healthy levels of prolactin and estrogens in women with SSD.

Total cholesterol mediates the association between history of gestational diabetes mellitus and bone mineral density in US women aged 20-49 years.

OBJECTIVE: The aim of this study is to investigate the potential association between a history of gestational diabetes mellitus (GDM) and lumbar bone mineral density (BMD) among premenopausal women, with an additional examination of the mediating role of serum total cholesterol (TC). METHODS: In this cross-sectional study, 1809 women aged 20-49 years with at least one live birth between 2011 and 2018, drawn from the NHANES dataset, were analyzed. GDM history was identified through questionnaires. Using weighted multiple linear regression, we assessed the relationship between GDM history and lumbar BMD. Additionally, mediation analysis was performed to investigate the potential mediating role of TC. RESULTS: The fully adjusted linear regression model revealed a negative association between a history of GDM and lumbar BMD, indicating a reduction in lumbar BMD (ß = -0.023, 95% CI: -0.043, -0.003, P = 0.0275). Subgroup analysis highlighted a more pronounced trend in individuals aged ≥ 35 years and with a body mass index ≥ 30 kg/m². Furthermore, mediation analysis demonstrated a significant direct effect of a history of GDM on lumbar BMD (P < 0.0001), with serum TC playing a partial mediating role in this interaction (5.33%, P = 0.028). CONCLUSIONS: In women aged 20-49 years within the United States, a history of GDM was associated with diminished lumbar BMD, potentially mediated through serum TC.

What Women Want? The State of the Art regarding the Treatment of Young Women with Hypoactive Sexual Desire Disorder.

BACKGROUND: Hypoactive sexual desire disorder (HSDD) in premenopausal women involves biological, psychological, and social aspects. In the European Society for Sexual Medicine meeting in Rotterdam in February 2023, several leading experts in the field discussed the multifaceted nature of this disorder and the state of the art regarding treatment at a round table. This review reflects the information discussed at this event and further discusses current controversies. SUMMARY: HSDD is the most prevalent female-estimated sexual disorder reported by 28% of the 40% premenopausal women with sexual dysfunction. Flibanserin and bremelanotide are the only approved medications to treat HSDD in the USA, and none are approved in Europe. Lybrido, Lybridos, and Lorexys are under development. There are several psychological factors with impact in sexual desire, including depression and sexual abuse. Feminine sexual scripts, the pleasure gap, and structural inequalities also affect sexual desire. Evidence strongly supports the value of combining medical and psychological approaches in the treatment of HSDD, but there is ongoing controversy regarding the pharmacological treatment of young women with HSDD. However, some women seem open and would like to have access to drug treatment. KEY MESSAGES: The treatment of HSDD in young women requires a mixed treatment approach that addresses the disorder's complexity. Despite clinicians seeming to be divided between using pharmacological and/or psychosocial approaches, some women might respond better to one type of intervention over the others. This calls for the development of tools that assess the best approach for each person, including their will and informed choice.

The impact of tamoxifen treatment on voice parameters in premenopausal women with breast cancer.

OBJECTIVE: The study aims to investigate the estrogen-agonistic effects of tamoxifen on voice parameters in premenopausal women diagnosed with breast cancer. METHODS: A total of 108 premenopausal women were included, segmented into distinct treatment groups and a control group. Objective sound analysis was conducted using robust statistical methods, employing SPSS 25.0 for data analysis. RESULTS: The study identified a statistically significant reduction in Jitter values across all treatment groups compared to the control group. No significant changes were observed in other voice quality parameters such as F0, Shimmer, NHR, and HNR. CONCLUSIONS: The findings suggest that tamoxifen may have an estrogen-agonistic effect on voice quality, thereby potentially influencing future treatment protocols. This research fills a critical void in existing literature and sets the stage for more comprehensive studies that consider affects of hormonal therapies to voice.

Premenopausal bilateral oophorectomy and brain white matter brain integrity in later-life.

INTRODUCTION: Premenopausal bilateral oophorectomy (PBO) is associated with later-life cognition, but the underlying brain changes remain unclear. We assessed the impact of PBO and PBO age on white matter integrity. METHODS: Female participants with regional diffusion tensor imaging (DTI) metrics of fractional anisotropy (FA) and mean diffusivity (MD) were included (22 with PBO < 40 years; 43 with PBO 40-45 years; 39 with PBO 46-49 years; 907 referents without PBO < 50 years). Linear regression models adjusted for age and apolipoprotein E (APOE) genotype. RESULTS: Females with PBO < 40 years, compared to referents, had lower FA and higher MD in the anterior corona radiata, genu of the corpus collosum, inferior fronto-occipital fasciculus, superior occipital, and superior temporal white matter. Females who underwent PBO between 45 and 49 also had some changes in white matter integrity. DISCUSSION: Females who underwent PBO < 40 years had reduced white matter integrity across multiple regions in later-life. These results are important for females considering PBO for noncancerous conditions. HIGHLIGHTS: Females with premenopausal bilateral oophorectomy (PBO) < 40 years had lower FA versus referents. Females with PBO < 40 years had higher MD in many regions versus referents. Adjusting for estrogen replacement therapy use did not attenuate results. Females with PBO 45-49 years also had some white matter changes versus referents.

Lipidome of mammographic breast density in premenopausal women.

BACKGROUND: High mammographic breast density (MBD) is a strong risk factor for breast cancer development, but the biological mechanisms underlying MBD are unclear. Lipids play important roles in cell differentiation, and perturbations in lipid metabolism are implicated in cancer development. Nevertheless, no study has applied untargeted lipidomics to profile the lipidome of MBD. Through this study, our goal is to characterize the lipidome of MBD in premenopausal women. METHODS: Premenopausal women were recruited during their annual screening mammogram at the Washington University School of Medicine in St. Louis, MO. Untargeted lipidomic profiling for 982 lipid species was performed at Metabolon (Durham, NC®), and volumetric measures of MBD (volumetric percent density (VPD), dense volume (DV), and non-dense volume (NDV)) was assessed using Volpara 1.5 (Volpara Health®). We performed multivariable linear regression models to investigate the associations of lipid species with MBD and calculated the covariate-adjusted least square mean of MBD by quartiles of lipid species. MBD measures were log10 transformed, and lipid species were standardized. Linear coefficients of MBD were back-transformed and considered significant if the Bonferroni corrected p-value was < 0.05. RESULTS: Of the 705 premenopausal women, 72% were non-Hispanic white, and 23% were non-Hispanic black. Mean age, and BMI were 46 years and 30 kg/m2, respectively. Fifty-six lipid species were significantly associated with VPD (52 inversely and 4 positively). The lipid species with positive associations were phosphatidylcholine (PC)(18:1/18:1), lysophosphatidylcholine (LPC)(18:1), lactosylceramide (LCER)(14:0), and phosphatidylinositol (PI)(18:1/18:1). VPD increased across quartiles of PI(18:1/18:1): (Q1 = 7.5%, Q2 = 7.7%, Q3 = 8.4%, Q4 = 9.4%, Bonferroni p-trend = 0.02). The lipid species that were inversely associated with VPD were mostly from the triacylglycerol (N = 43) and diacylglycerol (N = 7) sub-pathways. Lipid species explained some of the variation in VPD. The inclusion of lipid species increased the adjusted R2 from 0.45, for a model that includes known determinants of VPD, to 0.59. CONCLUSIONS: We report novel lipid species that are associated with MBD in premenopausal women. Studies are needed to validate our results and the translational potential.

Tamoxifen-predictive value of gene expression signatures in premenopausal breast cancer: data from the randomized SBII:2 trial.

BACKGROUND: Gene expression (GEX) signatures in breast cancer provide prognostic information, but little is known about their predictive value for tamoxifen treatment. We examined the tamoxifen-predictive value and prognostic effects of different GEX signatures in premenopausal women with early breast cancer. METHODS: RNA from formalin-fixed paraffin-embedded tumor tissue from premenopausal women randomized between two years of tamoxifen treatment and no systemic treatment was extracted and successfully subjected to GEX profiling (n = 437, NanoString Breast Cancer 360™ panel). The median follow-up periods for a recurrence-free interval (RFi) and overall survival (OS) were 28 and 33 years, respectively. Associations between GEX signatures and tamoxifen effect were assessed in patients with estrogen receptor-positive/human epidermal growth factor receptor 2-negative (ER+ /HER2-) tumors using Kaplan-Meier estimates and Cox regression. The prognostic effects of GEX signatures were studied in the entire cohort. False discovery rate adjustments (q-values) were applied to account for multiple hypothesis testing. RESULTS: In patients with ER+/HER2- tumors, FOXA1 expression below the median was associated with an improved effect of tamoxifen after 10 years with regard to RFi (hazard ratio [HR]FOXA1(high) = 1.04, 95% CI = 0.61-1.76, HRFOXA1(low) = 0.30, 95% CI = 0.14-0.67, qinteraction = 0.0013), and a resembling trend was observed for AR (HRAR(high) = 1.15, 95% CI = 0.60-2.20, HRAR(low) = 0.42, 95% CI = 0.24-0.75, qinteraction = 0.87). Similar patterns were observed for OS. Tamoxifen was in the same subgroup most beneficial for RFi in patients with low ESR1 expression (HRRFi ESR1(high) = 0.76, 95% CI = 0.43-1.35, HRRFi, ESR1(low) = 0.56, 95% CI = 0.29-1.06, qinteraction = 0.37). Irrespective of molecular subtype, higher levels of ESR1, Mast cells, and PGR on a continuous scale were correlated with improved 10 years RFi (HRESR1 = 0.80, 95% CI = 0.69-0.92, q = 0.005; HRMast cells = 0.74, 95% CI = 0.65-0.85, q < 0.0001; and HRPGR = 0.78, 95% CI = 0.68-0.89, q = 0.002). For BC proliferation and Hypoxia, higher scores associated with worse outcomes (HRBCproliferation = 1.54, 95% CI = 1.33-1.79, q < 0.0001; HRHypoxia = 1.38, 95% CI = 1.20-1.58, q < 0.0001). The results were similar for OS. CONCLUSIONS: Expression of FOXA1 is a promising predictive biomarker for tamoxifen effect in ER+/HER2- premenopausal breast cancer. In addition, each of the signatures BC proliferation, Hypoxia, Mast cells, and the GEX of AR, ESR1, and PGR had prognostic value, also after adjusting for established prognostic factors.

Sleep efficiency and PTSD symptom severity predict microvascular endothelial function and arterial stiffness in young, trauma-exposed women.

Posttraumatic stress disorder (PTSD) is linked to sleep disturbances and significantly higher risk of developing cardiovascular disease (CVD). Furthermore, vascular dysfunction and sleep are independently associated with CVD. Uncovering the link between PTSD symptom severity, sleep disturbances, and vascular function could shine a light on mechanisms of CVD risk in trauma-exposed young women. The purpose of the present study was to investigate the individual and combined effects of sleep efficiency and PTSD symptom severity on vascular function. We recruited 60 otherwise healthy women [age, 26 ± 7 yr and body mass index (BMI), 27.7 ± 6.5 kg/m2] who had been exposed to trauma. We objectively quantified sleep efficiency (SE) using actigraphy, microvascular endothelial function via Framingham reactive hyperemia index (fRHI), and arterial stiffness via pulse-wave velocity (PWV). PTSD symptom severity was assessed using the PTSD checklist for fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) (PCL5). PWV was correlated with age (r = 0.490, P < 0.001) and BMI (r = 0.484, P < 0.001). In addition, fRHI was positively correlated with SE (r = 0.409, P = 0.001) and negatively correlated with PTSD symptoms (r = -0.382, P = 0.002). To explore the predictive value of SE and PTSD symptoms on PWV and fRHI, we conducted two multivariate linear regression models. The model predicting PWV was significant (R2 = 0.584, P < 0.001) with age, BMI, blood pressure, and SE emerging as predictors. Likewise, the model predicting fRHI was significant (R2 = 0.360, P < 0.001) with both PTSD symptoms and SE as significant predictors. Our results suggest that although PTSD symptoms mainly impact microvascular endothelial function, sleep efficiency is additionally associated with arterial stiffness in young trauma-exposed women, after controlling for age and BMI.NEW & NOTEWORTHY This is the first study to investigate the individual and combined impacts of objective sleep and PTSD symptoms severity on arterial stiffness and microvascular endothelial function in young premenopausal women. We report that in young trauma-exposed women, although low sleep efficiency is associated with overall vascular function (i.e., microvascular endothelial function and arterial stiffness), the severity of PTSD symptoms is specifically associated with microvascular endothelial function, after accounting for age and body mass index.
