Does delivering chest compressions to patients who are not in cardiac arrest cause unintentional injury? A systematic review.

Background: Chest compressions are life-saving in cardiac arrest but concern by layperson of causing unintentional injury to patients who are not in cardiac arrest may limit provision and therefore delay initiation when required.

Aim: To perform a systematic review of the evidence to identify if; among patients not in cardiac arrest outside of a hospital, does provision of chest compressions from a layperson, compared to no use of chest compressions, worsen outcomes.

Method: We searched Medline (Ovid), Web of Science Core Collection (clarivate) and Cinahl (Ebsco).

Diagnostic Performance of Artificial Intelligence-Based Angiography-Derived Non-Hyperemic Pressure Ratio Using Pressure Wire as Reference.

Background: The angiography-derived non-hyperemic pressure ratio (angioNHPR) is a novel index of NHPR based on artificial intelligence (AI) that does not require pressure wires. We investigated the diagnostic accuracy of angioNHPR for detecting hemodynamically relevant coronary artery disease.

Methods And Results: In this retrospective single-center study, angioNHPR was assessed using the invasive NHPR as the reference standard.

A case report of an individual with Creutzfeldt-Jakob disease characterized by prolonged isolated thalamic lesions and rare MM2-cortical-type pathology.

Background: Diffusion-weighted magnetic resonance imaging (DWI) is essential for diagnosing Creutzfeldt-Jakob disease (CJD). Thalamic lesions are rarely detected by DWI in sporadic CJD (sCJD) cases with methionine homozygosity at polymorphic codon 129 (129MM) of the prion protein (PrP) gene. Here, we describe an unusual sCJD case, characterized by prolonged isolated thalamic diffusion hyperintensities and atypical brain pathology, in combination with the 129MM genotype.

Resuscitation Attempt and Outcomes in Patients With Asystole Out-of-Hospital Cardiac Arrest.

Importance: Little is known about the epidemiology of out-of-hospital cardiac arrest (OHCA) in patients with asystole in countries where prehospital resuscitation is not withheld or terminated.

Objective: To investigate the secular trends in the patient outcomes and advanced life support (ALS) procedures and evaluate the association of ALS procedures with favorable outcomes among patients with OHCA and asystole.

Design, Setting, And Participants: This cohort study analyzed data from a nationwide prospective OHCA registry in Japan.

LiNbHO: a new transition-metal oxyhydride with rock-salt-type structure.

Transition-metal oxyhydrides are an emerging class of functional materials; however, the known compounds have mostly been limited to perovskite-type sturctures. Here, we successfully synthesized LiNbHO, the first example of a rock-salt-type transition-metal oxyhydride, using mechanochemical methods. Galvanostatic charge/discharge tests revealed that LiNbHO functions as an electrode for lithium secondary batteries.

Association Between Direct Oral Anticoagulant Score and Bleeding Events in Patients With Atrial Fibrillation Following Transcatheter Aortic Valve Replacement: A Retrospective Multicenter Cohort Study.

Background: The Direct Oral Anticoagulant (DOAC) Score can predict bleeding risk in patients with atrial fibrillation taking DOACs; however, it lacks external validation. Therefore, this study aimed to assess the association between the DOAC Score and bleeding events in patients with atrial fibrillation who underwent transcatheter aortic valve replacement.

Methods And Results: This retrospective multicenter cohort study included patients with atrial fibrillation who underwent transcatheter aortic valve replacement, as registered in a Japanese multicenter registry.

Evaluation of Preoperative Low-flow Areas in STA-MCA Bypass Surgery Using Vascular Fusion Map Image.

Background: The superficial temporal artery-middle cerebral artery (STA-MCA) bypass surgery requires an anastomosis of the STA to an MCA with diminished blood flow. However, identifying the precise location of the MCA with reduced flow preoperatively is challenging as it often remains nonvisualized. To address this issue, we developed a novel technique, the area target bypass (ATB) method, to infer the location of the responsible vessel for low-flow areas.

Assessment of anti-Müllerian hormone levels as a reproductive indicator in Japanese Black cattle.

The size of the ovarian reserve, an indicator of the number of primordial follicles, varies widely among individuals, and declines with age. However, the association between the ovarian reserve and fertility remains unclear. Therefore, in the present study, we analyzed the relationship between plasma concentrations of anti-Müllerian hormone (AMH), a marker of ovarian reserve, and reproductive outcomes in Japanese Black cattle.

Mapping Glasgow Coma scale to AVPU scores among adults in the prehospital setting.

Objective: To develop a translation between the Glasgow Come Scale and the Alert-Verbal-Pain-Unresponsive (AVPU) scale among adults with out-of-hospital emergencies.

Methods: We performed a retrospective analysis of adults (≥18 years) from the 2022 National Emergency Medical Services (EMS) Information System with a ground scene encounter with a concurrently documented GCS and AVPU assessment. Using a training partition of 2.

Proton Intercalation into an Open-Tunnel Bronze Phase with Near-Zero Volume Change.

Managing safety and supply-chain risks associated with lithium-ion batteries (LIBs) is an urgent task for sustainable development. Aqueous proton batteries are attractive alternatives to LIBs because using water and protons addresses these two risks. However, most host materials undergo large volume changes upon H intercalation, which induces intraparticle cracking to accelerates parasitic reactions.

AMALRIC TRIANGULAR SIGN AND CAROTID DOPPLER ULTRASONOGRAPHIC FINDINGS IN CENTRAL RETINAL ARTERY OCCLUSION.

Purpose: The aim of this study was to determine the incidence of the Amalric triangular sign (ATS) in patients with central retinal artery occlusion and investigate its association with visual function and carotid Doppler ultrasonography findings.

Methods: A retrospective chart review was conducted on 21 eyes from 21 patients with complete central retinal artery occlusion. Best-corrected visual acuity and carotid Doppler ultrasonography findings [peak systolic velocity, end-diastolic velocity, and resistance index (RI) = (PSV - EDV)/PSV] were investigated.

[Questionnaire Survey on Early-Stage Hepatocellular Carcinoma in Patients and Physicians].

We conducted an online questionnaire survey to investigate changes in well-being and anxiety in patients with hepatocellular carcinoma requiring repeated locoregional therapy(hepatectomy/ablation)and the differences between patients' and treating physicians' perceptions of what is important to patients when selecting treatment. Between December 2022 and January 2023, we collected responses from 162 patients and 115 physicians in Japan. Results showed no clinically significant changes in well-being over time.

Immunohistochemistry was performed in paraffin-embedded tumor tissue sections to determine the protein expression statuses in tumor cells.

Clinical, Pathological and Endoscopic Features of Neoplastic or Non-neoplastic Reddish Depressed Lesions after Helicobacter pylori Eradication.

Background And Aims: Early gastric cancers (EGCs) after Helicobacter pylori (H. pylori) eradication often appear as reddish depressed lesions (RDLs); the same features are also appeared in benign stomachs after eradication. We compared clinic-pathological and endoscopic features of benign and neoplastic RDLs after H.

Expression and localization of anti-Müllerian hormone and its receptors in bovine corpus luteum.

Although anti-Müllerian hormone (AMH) is involved in the regulation of granulosa cell function in female animals, its role in tissues other than ovarian follicles remains poorly understood. It has also been suggested that cows with high circulating AMH concentrations have increased fertility; however, the mechanism has not been elucidated. This study was conducted to identify the presence of the AMH-signaling system and its target cells in the bovine corpus luteum formed from an ovulated follicle.
