Stress Management and Biological Age in Breast Cancer Patients.RCT
Intense stress has harmful effects on the body, contributing to various disorders. Breast cancer patients experience a build-up of stress due to their diagnosis and treatments. Stress can cause epigenetic changes in a cellular level (such as accelerated increase in biological age) that may negatively affect oncological treatments. This study aims to investigate the effect of stress management, specifically the Pythagorean Self-Awareness Intervention, on telomere length in T-leukocytes of breast cancer patients after completing all treatments except hormonal therapy. The study involves self-referred questionnaires and blood material extraction. Understanding the role of stress management in breast cancer may lead to improved patient outcomes and survival rates.

Does Recombinant FSH (rFSH, i.g. Gonal F®) as Compared to Human Menopausal Gonadotrophin (hMG) Affect Telomere Length of Cumulus Cells During Antral Follicle Growth and Impact Blastocyst Status?
Gonal-F® (follitropin alfa) is a recombinant FSH without LH activity, while Menopur® contains both LH and hCG. The MEGASET trial compared Menopur® and Gonal-F® in GnRH antagonist cycles with SET, showing similar efficacy. A subsequent study (MEGASET-HR) in high responders found ongoing pregnancy rates of 35.5% for Menopur® and 30.7% for Gonal-F®, with a lower early pregnancy loss for Menopur® (14.5% vs 25.5%). Telomere length (TL) in oocyte cumulus cells (CC) correlates with oocyte quality and embryo outcomes. This study aims to assess whether stimulation type (hMG vs. Gonal-F) affects TL in CC and subsequent blastocyst development. A randomized, open-label, cross-over study in normo-responders will analyze telomere length, embryo quality, and hormonal markers.

Mitigating Heat Stress Among Rickshaw Drivers in Bangladesh
The goal of the experimental study is to understand the impact of heat stress on core temperature and telomere length. Investigators will recruit rickshaw drivers who use manual power to push their rickshaws and randomly assign half of them to receive battery-powered rickshaws to use for four months. Investigators will assess how this change impacts their core body temperature while they work, the length of their telomeres (caps on the end of DNA that are associated with aging), and kidney function.
