Patients suffering from cholelithiasis have an increased risk of developing cardiovascular complications, particularly ischemic myocardial disease. Ursodeoxycholic acid (UDCA), already used in clinical practice for the treatment of cholelithiasis and related conditions, has proven antioxidative, anti-inflammatory, and cytoprotective effects. Therefore, the aim of this study was to investigate the cardioprotective effect of UDCA pre-treatment on isoprenaline-induced myocardial injury in rats.

Article Synopsis
  • Radioligand therapy (RLT) with Lu-labelled prostate specific membrane antigen ([Lu]Lu-PSMA-X) is showing promise as a treatment for metastatic castration-resistant prostate cancer (mCRPC), especially for those who haven't received taxane chemotherapy.
  • This study conducted a systematic review and meta-analysis to compare the efficacy of [Lu]Lu-PSMA-X to traditional taxane chemotherapy in patients who haven't been treated with taxane.
  • The results indicated that both treatment groups had similar rates of prostate specific antigen (PSA) response, suggesting that [Lu]Lu-PSMA-X could be a viable option for mCRPC patients who are taxane-naïve.

Does patient-ventilator asynchrony really matter?

Curr Opin Crit Care

February 2025

Keenan Centre for Biomedical Research, Li Ka Shing Knowledge Institute, Unity Health Toronto.

Purpose Of Review: Past observational studies have reported the association between patient-ventilator asynchronies and poor clinical outcomes, namely longer duration of mechanical ventilation and higher mortality. But causality has remained undetermined. During the era of lung and diaphragm protective ventilation, should we revolutionize our clinical practice to detect and treat dyssynchrony?

Recent Findings: Clinicians' ability to recognize asynchronies is typically low.

Sheep was one of the first domesticated animals in Neolithic West Eurasia. The zooarchaeological record suggests that domestication first took place in Southwest Asia, although much remains unresolved about the precise location(s) and timing(s) of earliest domestication, or the post-domestication history of sheep. Here, we present 24 new partial sheep paleogenomes, including a 13,000-year-old Epipaleolithic Central Anatolian wild sheep, as well as 14 domestic sheep from Neolithic Anatolia, two from Neolithic Iran, two from Neolithic Iberia, three from Neolithic France, and one each from Late Neolithic/Bronze Age Baltic and South Russia, in addition to five present-day Central Anatolian Mouflons and two present-day Cyprian Mouflons.

Smoke-free legislation has been shown to positively impact reducing secondhand smoke (SHS) exposure, especially in countries that have implemented comprehensive legislation rather than partial bans. Also, secondhand aerosols (SHA) that come from the heating of tobacco or liquids, with or without nicotine, in electronic nicotine delivery systems (ENDS) have been proven to increase levels of harmful substances in the air. Therefore, protection against SHS and SHA exposure and expansion of smoke- and aerosol-free environments (SAFE) should be taken into account when creating or trying to expand or enforce clean air policies.

Article Synopsis
  • The study focused on establishing continuous reference intervals for cerebrospinal fluid (CSF) biomarkers homovanillic acid (HVA) and 5-hydroxyindoleacetic acid (5-HIAA), which are important for diagnosing neurological diseases related to dopamine and serotonin.
  • Utilizing data from a large cohort of pediatric patients, researchers created age-specific models to define these intervals more accurately, addressing the issue of not having healthy control groups.
  • The results showed that the continuous reference intervals reduced the number of secondary deficiencies identified and found no significant links between HVA and 5-HIAA levels and the effects of antiepileptic or neuroleptic medications, indicating that these biomarkers may not always correlate with neurological disorders.
