RESUMO

Premature ovarian insufficiency and ovarian aging are complex conditions that affect women's reproductive health and overall well-being. They are both characterized by hypergonadotropic hypogonadism and infertility, and together affect about 1 in 100 women by the age of 40. This review explores the influence of environmental factors on the development and progression of premature ovarian insufficiency and ovarian aging. When referring to environmental factors, we include a wide range of external agents and conditions, including chemicals, socioeconomic factors and lifestyle choices. Through a review of the literature, we attempt to highlight the link between environmental factors and ovarian health. We examine the impact of endocrine-disrupting chemicals, such as bisphenol A and phthalates, on ovarian function and investigate the mechanisms by which these chemicals can disrupt hormone signaling pathways, leading to alterations in ovarian reserve, oocyte quality, and folliculogenesis. Moreover, we explore lifestyle factors like obesity, stress, smoking and alcohol in relation to their effects on ovarian aging. Epigenetic changes may play a crucial role in the prevalence of premature ovarian insufficiency. Understanding the impact of environmental factors on premature ovarian insufficiency and ovarian aging is very important in public and clinical health contexts. By identifying risk factors, healthcare providers can develop targeted and strategic prevention and intervention plans. Furthermore, this knowledge can promote reproductive health and minimize exposure to harmful environmental agents.

RESUMO

Bronchogenic cysts are rare congenital anomalies that they are usually diagnosed prenatally during the routine second trimester scan. We present such a rare case of bronchogenic cyst in a fetus. Our initial scan demonstrated a big cystic mass, which enlarged progressively causing shifting of the mediastinum and compression of the fetal heart. Consequent hydrops fetalis was treated with thoracoamniotic shunt and the pregnancy continued with no further complications. Pontnatal period, surgery and long term follow-up was uneventful.

RESUMO

Breast cancer is the most common form of cancer and the second highest cause of cancer mortality in female patients. The significance of the expression of Galectin-3 has been correlated with various malignancy types and in data from several research papers, the expression of Galectin-3 has been associated with the progression and metastasis of breast cancer. In the present study, the authors' goal is to identify whether the expression of Galectin-3 in breast cancer can be associated with the presence and/or recurrence of a metastatic disease. Both Scopus and PubMed databases were utilized, by inputting the following combination of keywords: (((Breast) AND Metastasis)) AND ((Galectin 3) OR Galectin-3). The time of publication and text availability were not considered when searching the databases and all relevant articles in English were initially accepted. We included one case-control study, three retrospective case studies and one retrospective cohort study. In two of the included studies, the levels in concentration of Galectin-3 were not correlated with a significant difference in prognosis. In two studies, the lacking in expression of Galectin-3 was associated with a worse prognosis and in one of the studies selected, the elevated levels of Galectin-3 were correlated with recurrence of disease in triple negative breast cancer cases. For most of the studies selected for this review, the results were contradictory in regard to the role of Galectin-3 for prognosis and metastatic potential in female breast cancer patients. It is still unclear, whether Galectin-3 can be used as a prognostic marker for advanced breast cancer disease.
