The purpose of this study is to analyze the effect of two genetic polymorphisms, , and , on physical condition in a sample of active older women after a two-year training period. The sample was composed of 300 healthy women over the age of 60 who underwent a two-year training program. Adapted tests from the Senior Fitness Test were used. The genotyping of the polymorphisms was obtained from the participants' DNA via buccal swabs. The analysis of the polymorphism did not reveal differences between genotypes. The analysis of the polymorphism showed a favorable effect for the genotype in tests for leg strength (: 0.001) after training, compared to the other genotypes, and also in the analysis of the combined effect of the polymorphism (). The intragroup effect revealed an improvement in arm strength for carriers of the X allele after 24 months of training ( < 0.05). The endurance values significantly worsened in all study groups. Conclusions: The polymorphism of may have an important role in capacities related to muscle strength, providing a beneficial effect for carriers of the allele.

Background: Female sterilization, a safe, permanent method of contraception that blocks the fallopian tubes, has been in use since the 19th century. The procedure necessitates informed consent, a critical step that has been marred by reports of forced sterilization since World War II. These incidents often stem from inadequate consent processes where ethical principles are overlooked or deliberately flouted.

Background: De-intensification of anti-cancer therapy without significantly affecting outcomes is an important goal. Omission of axillary surgery or breast radiation is considered a reasonable option in elderly patients with early-stage breast cancer and good prognostic factors. Data on avoidance of both axillary surgery and radiation therapy (RT) is scarce and inconclusive.

Department of Plastic and Breast Surgery, Zealand University Hospital, Roskilde, Denmark.
Objectives: This study aimed to investigate patients' use of electronic Patient-Reported Outcome Measures (ePROMs) and understand the demographic and clinical factors that may be correlated with patient responses to the BREAST-Q at the preoperative stage of breast cancer. The BREAST-Q is a PROM in questionnaire format, developed and validated to assess satisfaction and quality of life for breast surgery patients.The hypothesis tested is that considering disparities in geography, age and education among responders is essential for capturing a diverse patient population in future Patent-Reported Outcome Measures initiatives, examining how these characteristics are associated with Patent-Reported Outcome Measures utilisation and outcomes.
