Objective: We examined the relationship between breast cancer family history and mammographic breast density.
Methods: Participants included 35,019 postmenopausal women aged >or=40 years enrolled in a population-based mammography screening program. We collected data on the number and type of 1st and 2nd degree female relatives with a history of breast cancer and their ages at diagnosis. We used the Breast Imaging Reporting and Data System breast density categories to identify women with fatty (1 = almost entirely fatty or 2 = scattered fibroglandular tissue) and dense (3 = heterogeneously dense or 4 = extremely dense) breasts. We used logistic regression to calculate odds ratios (OR) and 95% confidence intervals for dense (N = 18,111) compared to fatty breasts (N = 16,908).
Results: The odds of having dense breasts were 17% greater for women with affected 1st degree relatives than women with no family history. The odds increased with more affected 1st degree relatives [>or=3 vs. none (OR = 1.46; 1.05-2.01)] and among women with >or=1 affected 1st degree relative diagnosed <50 years (OR = 1.22; 1.10-1.34).
Conclusions: Having a family history of breast cancer was more strongly associated with mammographic breast density when the affected relatives were more genetically similar. There may be common, yet undiscovered, genetic elements that affect breast cancer and mammographic breast density.

Objectives: To study the clinical manifestations and genetic characteristics of children with maturity-onset diabetes of the young type 2 (MODY2), aiming to enhance the recognition of MODY2 in clinical practice.
Methods: A retrospective analysis was conducted on the clinical data of 13 children diagnosed with MODY2 at the Department of Pediatrics of Tongji Hospital of Tongji Medical College of Huazhong University of Science and Technology from August 2017 to July 2023.
Results: All 13 MODY2 children had a positive family history of diabetes and were found to have mild fasting hyperglycemia [(6.

Despite maintaining a lower mortality rate and greater control of victims infected by COVID-19, the world's population and science are still confronted with this coronavirus. Therefore, the aim was to assess the association between sociodemographic factors and the level of knowledge and attitudes of dental students regarding disinfection as a control measure to reduce the spread of COVID-19. This cross-sectional study evaluated 503 dental students from the capital city and one Peruvian province between February and June 2022.

Background: Research suggests that although men have a higher cardiovascular disease (CVD) rate, women with CVD are more likely to experience a poorer prognosis, possibly owing to incorrect diagnosis and poorer treatment. A question not yet addressed is whether some of this inequality could be due to sex bias when selecting patients for operation.
Method: The participants were from the Scottish Heart Health Extended Cohort who had been admitted to hospital with a cardiovascular diagnosis over the study period.
Psychopathology trajectories and relapse in first episode schizophrenia with assured long-acting injectable adherence over 24 months.

Background: Relapse following a first episode of schizophrenia (FES) is common and often results in serious adverse psychosocial consequences. Treatment non-adherence is a key risk factor for relapse, but why relapse occurs despite antipsychotic treatment adherence remains unclear. This study examined the differences in FES psychopathology trajectories over 24-months with assured long-acting injectable antipsychotic (LAIA) treatment, to control for treatment adherence between those who relapsed and those who did not and what moderates these group differences.
