Capnographic monitoring using a novel mainstream system during endoscopic ultrasound and endoscopic retrograde cholangiopancreatography: A prospective randomized controlled trial.

Background/purpose: Insufficient studies exist on capnography efficacy during endoscopic ultrasound or endoscopic retrograde cholangiopancreatography, and no definitive conclusions have been drawn. To evaluate the feasibility and efficacy of a novel mainstream capnography using an over-the-biteblock end-tidal CO (EtCO) detector in decreasing the risk of hypoxemia during endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP).

Methods: Patients undergoing EUS or ERCP with conscious sedation at a single Japanese center were randomized to a control or a novel capnography monitored (intervention) group in a 1:1 ratio.

Public Perspectives on Consent for and Governance of Biobanking in Japan.

Through strengthened biobank governance, broad consent has been widely accepted as a means to replace donors' discretion based on the information of individual research protocols. Trust and other ethical and social notions, such as reciprocity and solidarity, are key concepts that support biobank governance. The types of allowed broad consent are several; however, they remain unclear, and whether these ethical and social notions are associated with public attitudes toward the consent model is not fully understood.

Combination of a membrane bioreactor with a rotating biological contactor holding several diverse metazoans can reduce excess sludge with fouling mitigation.

In a membrane bioreactor (MBR) system, in situ sludge reduction techniques induce membrane fouling. To address this challenge, we incorporated a rotating mesh carrier, which can adsorb organic matter and provide a habitat for metazoans, into the anoxic tank of a conventional anoxic/oxic-MBR (A/O-MBR) system, termed rotating biological contactor-MBR (RBC-MBR), and evaluated treatment performance. Over 151 days, lab-scale RBC-MBR and A/O-MBR were used to treat municipal sewage.

The Effects of Adlay Tea Intake on Immune Homeostasis and Vascular Endothelial Function in Healthy Adults: A Randomized, Double-Blind, Parallel-Group Comparative Study.

Excessive immune response and inflammation are associated with an increased risk of various diseases. In particular, excessive myeloperoxidase (MPO) activity in neutrophils causes inflammatory reactions and lifestyle-related diseases. Adlay has a long history of being used as a traditional Chinese medicine.

Harnessing iron materials for enhanced decolorization of azo dye wastewater: A comprehensive review.

Highly colored azo dye-contaminated wastewater poses significant environmental threats and requires effective treatment before discharge. The anaerobic azo dye treatment method is a cost-effective and environmentally friendly solution, while its time-consuming and inefficient processes present substantial challenges for industrial scaling. Thus, the use of iron materials presents a promising alternative.

The Gap in Attitudes Toward Withholding and Withdrawing Life-Sustaining Treatment Between Japanese Physicians and Citizens.

Background: According to some medical ethicists and professional guidelines, there is no ethical difference between withholding and withdrawing life-sustaining treatment. However, medical professionals do not always agree with this notion. Patients and their families may also not regard these decisions as equivalent.

Cross-cultural differences in prefrontal cortex activity in moral judgment: A functional near-infrared spectroscopy (fNIRS) study based on the CNI model.

Background: In the past, comparative cultural neurological studies of moral judgments have mainly focused on Eastern and Western groups. We initially examined Japanese and Chinese groups, both East Asian cultures. We utilized a recently proposed polynomial model known as the "consequences, norms, and generalized inaction" (CNI) model to investigate the variations in the overall prefrontal cortex activity between these two groups during moral judgment.

How do personality traits modulate real-world gaze behavior? Generated gaze data shows situation-dependent modulations.

It has both scientific and practical benefits to substantiate the theoretical prediction that personality (Big Five) traits systematically modulate gaze behavior in various real-world (working) situations. Nevertheless, previous methods that required controlled situations and large numbers of participants failed to incorporate real-world personality modulation analysis. One cause of this research gap is the mixed effects of individual attributes (e.

Clinical Ethics Consultation in Japan: What does it Mean to have a Functioning Ethics Consultation?

This research examines the current status of clinical ethics consultation (CEC) in Japan through a nationwide study conducted with chairs of ethics committees and clinical ethics committees among 1028 post-graduate clinical teaching hospitals. We also qualitatively analyzed their viewpoints of the CEC's benefits and problems related to hospital consultation services to identify the critical points for CEC and inform the development of a correctly functioning system. The questionnaire included structured questions about hospital CEC organization and service purpose and operation and open-ended questions about the benefits and problems of initiating CEC.

Role of amide proton transfer imaging in maximizing tumor resection in malignant glioma: a possibility to take the place of C-methionine positron emission tomography.

Background: Amide proton transfer (APT) imaging has been proposed as a technique to assess tumor metabolism. However, the relationship between APT imaging and other quantitative modalities including positron emission tomography (PET) has not been investigated in detail. This study aimed to evaluate the clinical usefulness of APT imaging in determining the metabolic status of malignant glioma and to compare findings with those from C-methionine (Met)-PET.

Should Physicians Be Permitted to Refuse Follow-Up Care to Patients Who Have Received an Organ Transplant Through Organ Trafficking?

In 2018, the Istanbul Declaration stated that organ transplantation via organ trafficking is a crime. Since then, the number of medical institutions in Japan who refuse follow-up care to patients who have undergone unethical organ transplantation overseas has been gradually increasing. Deterring transplant tourism involving organ trafficking is an issue that must be addressed by the government, medical institutions, and individual physicians.

Ethics Guideline Development for Neuroscience Research involving Patients with Mental Illness in Japan.

Unlabelled: This study aims to develop guidelines of key concepts and specific considerations to make the research more ethical when conducting neurological examinations and treatment interventions in mentally ill patients. We analyzed guideline development theory and literature, previous issues, and discussions with specialists of philosophy, medicine, sociology, and bioethics. The selection of research participants, drafting of intervention plans, and informed consent process were examined with reference to the dual burden; the minimal risk as a general rule of ethical allowance levels, assent and dissent to assess the individual's judgment capacity for consent, relational autonomy for personal consent with assistance by the proxy, and risk/benefit assessments.

Weight-Loss Interventions and Levonorgestrel Intrauterine System Implantation for Early-Stage Endometrial Cancer and Atypical Endometrial Hyperplasia to Reduce Perioperative Risk of Severely Obese Patients.

Endometrial cancer (EC) and atypical endometrial hyperplasia (AEH) are associated with obesity, which increases the perioperative morbidity and surgical difficulties in laparoscopic and robotic surgery. Weight-loss interventions (WLIs) are likely to reduce morbidity; however, delayed surgery may cause cancer progression. To minimize the tumor progression, levonorgestrel intrauterine system (LNG-IUS) with minimal side effects was used until the planned surgery.

Medroxyprogesterone as the Initial Systemic Treatment of Recurrent Endometrial Cancer: A Single Institutional Study.

Background/aim: Hormonal treatment is the preferred initial systemic therapy for patients with advanced or recurrent G1 or G2 endometrial cancer (EC) in terms of efficacy, toxicity, and economy. Few reports are available on the topic and we, therefore, conducted a retrospective study.

Patients And Methods: Patients with EC who received high-dose medroxyprogesterone (MPA) at our Hospital between January 2010 and December 2022 were reviewed.

Perceptions of Psychosocial and Ethical Issues and the Psychological Characteristics of Donors in the Clinical Setting of Living Kidney Donors: A Qualitative Study.

Background: There are several psychosocial and ethical issues surrounding the decision to be a living kidney donor. The present study aimed to determine the perceptions of psychosocial and ethical issues that living kidney donors may have, and analyze their psychological characteristics.

Exploring cultural and gender differences in moral judgment: A cross-cultural study based on the CNI model.

Unlabelled: Recently, researchers have proposed a polynomial model called the "consequences, norms, generalized inaction" (CNI) model for researching moral judgment. However, it is unclear whether the model can be used to explore cultural differences in moral judgment. In this study, we investigated the applicability of the CNI model of moral judgment to East Asian groups, and subsequently explored cultural and gender differences in moral judgment between East Asian (i.

Initiation and progression of Early-Stage microbial-driven membrane fouling in membrane bioreactors: a review.

Microbial biofilm development on the membrane surface of bioreactors results in membrane flux decline (biofouling). Biofouling is one of the most severe problems limiting the use of these bioreactors. For detailed understanding of the biofouling, microbial community and dissolved organic matter analyses have been performed in recent decades.

Itraconazole Modulates Phospholipid Levels in Tumor-associated Macrophages.

Background/aim: Itraconazole, an antifungal drug, repolarizes pro-tumorigenic M2 tumor-associated macrophages to anti-tumorigenic M1-like phenotypes, thereby inhibiting the proliferation of cancer cells; however, the underlying mechanism remains unclear. Therefore, we investigated the effect of itraconazole on membrane-associated lipids in tumor-associated macrophages (TAM).

Materials And Methods: M1 and M2 macrophages were derived from the human monocyte leukemia cell line (THP-1) and cultured with or without 10 μM itraconazole.

Comprehensive Genomic Profiling Detects Hereditary Cancers and Confers Survival Advantage in Patients With Gynaecological Cancers.

Background/aim: The clinical benefits of comprehensive genomic profiling (CGP) of tumours in patients with gynaecological cancers remain unknown. We investigated the utility of CGP in assessing patient survival and its efficacy in detecting hereditary cancers in gynaecological patients.

Patients And Methods: We retrospectively analysed the medical records of 104 gynaecological patients who underwent CGP between August 2018 and December 2022.

Clinical ethics problems in psychiatry and the need for clinical ethics consultation in Japan: A cross-sectional study.

Myeloid TLR4 signaling promotes post-injury withdrawal resolution of murine liver fibrosis.

The fate of resolution of liver fibrosis after withdrawal of liver injury is still incompletely elucidated. Toll-like receptor 4 (TLR4) in tissue fibroblasts is pro-fibrogenic. After withdrawal of liver injury, we unexpectedly observed a significant delay of fibrosis resolution as TLR4 signaling was pharmacologically inhibited in two murine models.
