Although alveolar hyperoxia exacerbates lung injury, clinical studies have failed to demonstrate the beneficial effects of lowering the fraction of inspired oxygen (FO) in patients with acute respiratory distress syndrome (ARDS). Atelectasis, which is commonly observed in ARDS, not only leads to hypoxemia but also contributes to lung injury through hypoxia-induced alveolar tissue inflammation. Therefore, it is possible that excessively low FO may enhance hypoxia-induced inflammation in atelectasis, and raising FO to an appropriate level may be a reasonable strategy for its mitigation.

Background: Paliperidone is a second-generation antipsychotic and the main active metabolite of risperidone, formulated to provide consistent therapeutic effects through an extended-release system, designed to provide consistent therapeutic effects through an extended-release formulation. While commonly used in clinical practice, switching from risperidone to paliperidone, particularly during valproate therapy, can pose challenges due to potential pharmacokinetic interactions that may increase the risk of extrapyramidal symptoms (EPS). Despite clinical observations suggesting these interactions, case reports documenting such adverse effects are scarce.

Objective: We sought to develop a machine learning (ML) preoperative model to predict bile leak following hepatectomy for primary and secondary liver cancer.

Methods: An eXtreme Gradient Boosting (XGBoost) model was developed to predict post-hepatectomy bile leak using data from the ACS-NSQIP database. The model was externally validated using data from hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC) multi-institutional databases.

Article Synopsis
  • Cryptorchidism is a common congenital condition in newborn males where one or both testes fail to descend into the scrotum, leading to potential infertility due to azoospermia.
  • Research using a mouse model of surgically induced cryptorchidism revealed changes in the epigenetic markers H3K27me3 and H3K9me3 in spermatogonial cells, with a specific loss of H3K27me3 linked to gene activation related to development and apoptosis.
  • The study indicates that elevated temperatures may enhance the activity of enzymes that demethylate H3K27, contributing to mRNA dysregulation and potentially impacting spermatogonial function.

Article Synopsis
  • Turner syndrome is a genetic disorder caused by the deletion of one X chromosome, leading to diverse karyotypes and phenotypes, but predicting phenotypes remains challenging due to mosaicism.
  • A study included 487 Turner women with non-mosaic X chromosome structural rearrangements and found prevalence rates of short stature (72.4%) and ovarian dysfunction (78.8%) linked to specific deletion groups.
  • Understanding the specific X chromosome breakpoints is crucial for managing Turner syndrome, particularly for predicting and addressing ovarian dysfunction and future fertility issues.

It is time for reform: Results from a questionnaire survey on the current status of next generation HBP surgeons in Japan.

J Hepatobiliary Pancreat Sci

December 2024

Division of Hepatobiliary and Pancreatic Surgery, Department of General Surgical Science, Graduate School of Medicine, Gunma University, Gunma, Japan.

A questionnaire survey was designed and performed to assess the current status of "next generation" hepatobiliary and pancreatic (HBP) surgeons regarding surgical training, career, recruiting, and work-life balance in Japan. Using a valid email address, a questionnaire was sent to members of the Japanese Society of Hepato-Biliary-Pancreatic Surgeons (JSHBPS) who were under 45 years old. The questionnaire comprised 50 questions across the following four sections: (i) board certification of JSHBPS, (ii) research activity and overseas study, (iii) recruiting, and (iv) work-life balance.

Objectives: New scores were developed to identify at-risk metabolic dysfunction-associated steatohepatitis (MASH) using multiparametric MRI (mpMRI).

Materials And Methods: A prospective study was conducted on 176 patients with suspected or diagnosed metabolic dysfunction-associated steatotic liver disease (MASLD) paired with an MR scan, vibration-controlled transient elastography (VCTE), and liver biopsy. Liver stiffness measurement (LSM) using magnetic resonance elastography (MRE), proton density fat fraction (PDFF), and mpMRI-based corrected T1 (cT1) were combined to develop a one-step strategy, named MPcT (MRE + PDFF + cT1, combined score), and a two-step strategy-MRE-based LSM followed by PDFF with cT1 (M-PcT, paired score) for diagnosing at-risk MASH.
