Int J Mol Sci

November 2024

Department of Genetics, Physical Anthropology and Animal Physiology, Faculty of Science and Technology, University of the Basque Country (UPV/EHU), Sarriena auzoa, 48940 Leioa, Spain.

Recurrent Pregnancy Loss (RPL), also named Recurrent Spontaneous Abortion (RSA), is a common fertility problem that refers to at least two consecutive pregnancy losses and affects 1-2% of couples all over the world. Despite common causes such as genetic abnormalities, uterine anomalies or hormonal and metabolic disorders, there is still a huge challenge in identifying the causes of about 40-60% of RPL patients. Circular RNAs (circRNAs) are endogenous ncRNAs with a unique closed-loop and single-stranded structure.

Stress enhances memory for previously encoded events depending on stressor recall.

Learn Mem

December 2024

Department of Cognitive Psychology, Institute of Psychology, University of Hamburg, 20146 Hamburg, Germany

Stressful events are typically well remembered, but their effects on memory for surrounding neutral events and the underlying mechanisms remain less clear. We hypothesized that stress would enhance memory for events surrounding the stressor, contingent on the memory of the stressor itself. Additionally, we predicted that memory for neutral events would be modulated by pairing them with stressor-related cues.

Article Synopsis
  • There is evidence suggesting that using stents or decompressing stomas before surgery for left-sided obstructive colon cancer (LSOCC) is safer than emergency surgery, particularly for patients aged 70 and older.
  • A study analyzing data from 2012 to 2020 showed a decrease in emergency resections, from 79.7% to 54.7%, with an increase in safer approaches like resection after stent or stoma.
  • Despite a national trend towards safer surgical methods, some hospitals still performed over 75% emergency resections, leading to higher mortality rates, emphasizing the need to follow updated guidelines for elderly patients.

Background: Neurofibromatosis Type 1 (NF1) is a congenital neurocutaneous disorder. As NF1 is incurable and presents with a wide range of physical and mental symptoms, knowledge of neurocognitive and behavioral functioning can be an important aid in understanding their functional impact, and developing treatment options. To date, studies in children with NF1 have shown dysfunction in several domains, but much less is known about cognition and behavior in adults with NF1.

Gender as a Contextual Factor in Quality of Life of Cancer Survivors: A Literature Review.

Oncol Res Treat

December 2024

Gender Research Unit, Department of Primary and Community Care, Radboud University Medical Center, Nijmegen, The Netherlands.

Background: Cancer survivorship brings numerous challenges extending beyond physical health to include psychological, social, and functional aspects that define the quality of life (QoL) of survivors. Although recognizing that diverse gender experiences lead to different ways of coping with these challenges, many clinical trials fail to account for the distinct constructs of "sex" and "gender," often conflating the two. This review highlights how gender-related aspects can manifest in core QoL domains for cancer survivors, emphasizing the importance of inclusive and effective support systems and interventions.

Study Question: What is the predictive value of oligomenorrhea and other PCOS diagnostic characteristics in adolescence (age 15-18 years) for future fertility and cardiovascular and metabolic health at adult age?

Summary Answer: Adolescents with oligomenorrhea are more often treated to conceive but are as likely to have as much children as those with regular periods, while persisting oligomenorrhea may associate more often with cardiovascular or metabolic problems.

What Is Known Already: Adolescents with oligomenorrhea have a high risk for adult PCOS associated with subfertility due to ovulatory disorders and long-term health risks. Longitudinal studies to estimate the extent of these risks with input starting at adolescence and covering the complete reproductive lifespan are lacking.

Gene expression analysis of ovarian follicles and stromal cells in girls with Turner syndrome.

Mol Hum Reprod

December 2024

Gynaecology Research Unit, Institut de Recherche Expérimentale et Clinique, Université Catholique de Louvain, Brussels, Belgium.

In patients with mosaic Turner syndrome, the ovarian somatic cells (granulosa and stromal cells) display a high level of aneuploidy with a 45,X karyotype, which may affect gene expression in the ovary and contribute to their reduced fertility. The aim of the current research is to study the effect of aneuploidy of somatic ovarian cells on gene expression in ovarian cortex stromal cells and small ovarian follicles from mosaic (45,X/46,XX) Turner syndrome patients. To this end, ovarian cortical tissue was obtained by laparoscopic surgery from eight mosaic Turner syndrome patients (aged 5-19 years) and eight controls (aged 6-18 years).
