The aim of this study is to investigate the role of genetic variation and DNA methylation of PEAR1 rs12041331 in high on-treatment platelet reactivity (HPR) and recurrent ischemic stroke (RIS). ⋯ The PEAR1 rs12041331 genetic polymorphism and DNA methylation may be among the genetic factors affecting HPR. The correlation between PEAR1 and RIS needs to be studied further.

We evaluated whether 12-week intake of molecular hydrogen (H2) in 5 overweight adults (3 women; age: 50.2 ±11.9 years, body mass index: 29.4 ±2.1 kg/m2) affects brain levels of the glutamate-glutamine-GABA cycle, critical amino acid neurotransmitters in the mechanism of neuronal activation during appetite regulation. ⋯ We showed a possible hydrogen-driven upregulation of neurotransmitters involved in appetite stimulation leading to hunger suppression and weight loss. Further studies analyzing appetite-controlling metabolic pathways affected by H2 would require monitoring of additional biomarkers of satiation and satiety during different feeding regimens.

Radical rectal cancer resection can lead to a long-term bowel function impairment known as low anterior resection syndrome (LARS). It remains unclear how to determine which patients are at a higher risk of developing LARS post-surgery. The POLARS tool was designed to predict the onset and severity of LARS in rectal cancer patients after surgery. The study aimed to assess the accuracy of POLARS in predicting the onset of LARS. ⋯ POLARS did not prove to be accurate in predicting the risk and severity of LARS in these patients, although the average numbers appear promising. Further evaluation of the POLARS tool using a larger cohort is needed.

Markers of iron homeostasis are related to insulin resistance (IR) in adults. However, studies in children and adolescents are scarce and show contradictory results. The aim was to evaluate the potential relationship between iron status markers and IR. Additionally, no previous study has explored the mutual effect of biomarkers of iron homeostasis and inflammation (i.e. high sensitivity C-reactive protein (hsCRP)), and adipokines (i.e. retinol-binding protein 4 (RBP4)) on IR in the cohort of adolescent girls. ⋯ Serum sTfR levels are independently associated with HOMA-IR, whereas higher serum ferritin levels together with higher RBP4 are related to higher HOMA-IR in adolescent girls.

The aim of this prospective trial was to evaluate the ovarian reserve with anti-Müllerian hormone (AMH), which is the best predictor of ovarian reserve, and perform histological analysis after exposure to cisplatin with a GnRH agonist or antagonist. ⋯ This is the first prospective randomized controlled study showing the protective effects of GnRH agonist and antagonist on ovarian reserve after cisplatin exposure in an animal model.
