Background: Patients with estrogen receptor (ER)-positive breast cancer (BC) can be treated with endocrine therapy targeting ER, however, metastatic recurrence occurs in 25% of the patients who have initially been treated. Secreted proteins from tumors play important roles in cancer metastasis but previous methods for isolating secretory proteins had limitations in identifying novel targets.

Methods: We applied an in situ secretory protein labeling technique using TurboID to analyze secretome from tamoxifen-resistant (TAMR) BC.

Purpose: To examine the discrepancy in breast density assessments by radiologists, LIBRA software, and AI algorithm and their association with breast cancer risk.

Methods: Among 74,610 Korean women aged ≥ 34 years, who underwent screening mammography, density estimates obtained from both LIBRA and the AI algorithm were compared to radiologists using BI-RADS density categories (A-D, designating C and D as dense breasts). The breast cancer risks were compared according to concordant or discordant dense breasts identified by radiologists, LIBRA, and AI.

Background: Taller women are at an increased risk of breast cancer; however, evidence regarding this in younger women is limited. This study investigated the association between body height and breast cancer risk in premenopausal Korean women aged <40 years.

Methods: Premenopausal women aged <40 years enroled in the Kangbuk Samsung Health Study (KSHS) and National Health Insurance Service-National Health Information Database (NHIS-NHID) were included in the analysis.

Article Synopsis
  • The study looked at how menopause affects the sleep quality of women, especially those from Asian backgrounds, since not much research has been done on them.
  • It involved 3,305 women who were checked for their sleep health and went through different stages of menopause over time, showing that sleep quality generally got worse during the late stages of menopause.
  • The findings suggest that being overweight can make sleep quality even worse, so it’s important for women going through menopause to monitor and improve their sleep.

Background CT performed for various clinical indications has the potential to predict cardiometabolic diseases. However, the predictive ability of individual CT parameters remains underexplored. Purpose To evaluate the ability of automated CT-derived markers to predict diabetes and associated cardiometabolic comorbidities.

Background: Overactive bladder (OAB) is a common condition in middle-aged and older women. It has been reported to be potentially linked to cognitive decline, particularly in older adults. This study investigated the association between OAB symptoms and cognitive impairment in middle-aged women.

Background: Artificial intelligence (AI) algorithms for the independent assessment of screening mammograms have not been well established in a large screening cohort of Asian women. We compared the performance of screening digital mammography considering breast density, between radiologists and AI standalone detection among Korean women.

Methods: We retrospectively included 89,855 Korean women who underwent their initial screening digital mammography from 2009 to 2020.

Article Synopsis
  • The study aimed to explore the link between body composition and breast cancer risk in premenopausal women, using data from the Kangbuk Samsung Cohort Study involving 125,188 participants.
  • Over an average follow-up of 6.7 years, 1,110 cases of breast cancer were identified, showing that higher body mass index (BMI) and waist circumference correlated with a lower risk of breast cancer.
  • Interestingly, while a higher fat mass to weight ratio was associated with reduced breast cancer risk, a higher muscle mass to weight ratio was linked to increased risk, suggesting a complex relationship between body composition and breast cancer outcomes.

Background: We investigated the association between vasomotor symptoms (VMSs) and the onset of depressive symptoms among premenopausal women.

Methods: This cross-sectional study included 4376 premenopausal women aged 42-52 years, and the cohort study included 2832 women without clinically relevant depressive symptoms at baseline. VMSs included the symptoms of hot flashes and night sweats.

Aims: Mammography, commonly used for breast cancer screening in women, can also predict cardiovascular disease. We developed mammography-based deep learning models for predicting coronary artery calcium (CAC) scores, an established predictor of coronary events.

Methods And Results: We evaluated a subset of Korean adults who underwent image mammography and CAC computed tomography and randomly selected approximately 80% of the participants as the training dataset, used to develop a convolutional neural network (CNN) to predict detectable CAC.

Despite the increasing prevalence of lean nonalcoholic fatty liver disease (NAFLD), its risk factors are not well established. We examined the association between long working hours and incident NAFLD in lean Korean workers with emphasis on sex-based effect modification. This cohort study involved 46,113 non-overweight (BMI < 23 kg/m) and NAFLD-free Korean workers (mean age, 35.

Unlabelled: Potentiating antitumor immunity is a promising therapeutic approach for treating a variety of cancers, including breast cancer. One potential strategy to promote antitumor immunity is targeting DNA damage response. Given that the nuclear receptor NR1D1 (also known as REV-ERBα) inhibits DNA repair in breast cancer cells, we explored the role of NR1D1 in antitumor CD8+ T-cell responses.

Objective: We examined the association between menopause symptoms and the prevalence of ideal cardiovascular health (CVH) metrics among premenopausal women.

Methods: This cross-sectional study comprised 4,611 premenopausal women aged 42 to 52 years. Data for CVH metrics were collected during health screening examinations.

Aims: In this study, we aimed to investigate previously unrecognized lipid metabolic perturbations in tamoxifen-resistant breast cancer (BC) by conducting comprehensive metabolomics and transcriptomics analysis. We identified the role of 3-hydroxy-3-methylglutary-coenzyme-A-synthase 2 (HMGCS2), a key enzyme responsible for ketogenesis, in tamoxifen-resistant BC growth.

Main Methods: Comprehensive metabolomics (CE-TOFMS, LC-TOFMS) and transcriptiomics analysis were performed to characterize metabolic pathways in tamoxifen-resistant BC cells.

In tumor microenvironment (TME), macrophages trigger and maintain inflammatory responses that promoting tumor progression. Many cellular proteins are secreted from tumors and modulate their own TME by modulating macrophage phenotypes. Recently, we reported that interferon-γ-inducible protein 16 (IFI16), which was identified as an innate immune DNA sensor recognizing foreign DNA, triggered type Ⅰ interferon responses in breast cancer (BC).

Article Synopsis
  • This study explores the link between anti-Müllerian hormone (AMH) levels and the onset of vasomotor symptoms (VMS) like hot flushes and night sweats in premenopausal women.
  • A cohort of 2041 women aged 42-52 was followed for an average of 4.4 years, revealing that 708 developed early-onset VMS.
  • Findings indicate that lower AMH levels are significantly associated with a higher risk of developing early-onset VMS, highlighting AMH's potential role in predicting these symptoms as women approach menopause.

The role of alcohol consumption in the risk of vasomotor symptoms (VMS), the most cardinal climacteric symptoms, is not well established. We examined their relationship with early-onset VMS among premenopausal women. Moderately-to-severely bothersome VMS, the primary outcome, was assessed using the Korean version of the Menopause-Specific Quality of Life questionnaire.
