Endoscopic transpapillary biliary forceps biopsy (TBFB) is a common method for obtaining specimens from biliary lesions. Its diagnostic yield is unsatisfactory; to overcome this disadvantage, a dedicated sheath has been developed. This study aimed to evaluate the outcomes of conventional TBFB and TBFB with a novel sheath device. Consecutive patients who underwent TBFB between January 2020 and December 2021 were retrospectively evaluated. The rate of obtaining adequate samples, failed attempts at forceps insertion into the bile duct, and sensitivity were compared between the two groups. Ninety-two patients who underwent 115 endoscopic retrograde cholangiopancreatographies (76 in the conventional group vs. 39 in the dedicated sheath group) were included. The rates of obtaining adequate samples, failed attempts of the forceps into the bile duct, and sensitivity were 72.4% vs. 89.7% ( = 0.03), 28.3% vs. 0% ( < 0.01), and 66.7% vs. 88.9% ( = 0.02), respectively. TBFB with the novel sheath device contributed to improved sensitivity for diagnosis of biliary stricture without insertion of forceps outside the bile duct.

Prevention of radial artery occlusion after transradial angiography and intervention: a best practice implementation project.
JBI Evid Implement
October 2024
Department of Cardiology, Huadong Hospital, Shanghai, China.
Introduction: Among the complications associated with transradial artery access, radial artery occlusion (RAO) is the most frequent and serious, limiting the reuse of the same radial artery for subsequent procedures and as a graft for coronary artery bypass grafting.
Objective: The objective of this project was to implement best practices to reduce the incidence of RAO, thereby enhancing the quality of patient care after transradial coronary angiography or intervention.
Methods: The project was conducted in cardiology department of the Huadong Hospital, Shanghai, China.

Background Traumatic brain injury (TBI) remains a foremost cause of death and disability globally, with elevated intracranial pressure (ICP) being a crucial factor in patient outcomes. While invasive monitoring is the gold standard for assessing ICP, it carries risks and is not always feasible. This study proposes a novel noninvasive parameter using computed tomography (CT) imaging.

Vascular hemostasis after venous and arterial access in cardiovascular procedures remains a challenge. As sheath size gets larger for structural heart and vascular procedures, no dedicated closure devices exist that can overcome all the challenges of achieving vascular hemostasis, in particular on the venous side. Efficiently and reliably ensuring hemostasis at the access point is crucial for enhancing the safety of a procedure.

Objectives: This study aims to investigate the etiological distribution of primary and metastatic malignancies around the elbow and the effect of surgical and adjuvant treatments on clinical outcome.
Patients And Methods: Between January 2006 and December 2020, medical records of a total of 33 patients with elbow neoplasm (15 males, 18 females; median age: 55 years; range, 39 to 71 years) who underwent surgical treatment and with or without clinical treatment were retrospectively analyzed. The outcomes and frequencies of the elbow metastatic and primary malignancies were evaluated.
Age-appropriate or delayed myelination? Scoring myelination in routine clinical MRI.
Eur J Paediatr Neurol
September 2024

Background: Assessment of myelination is a core issue in paediatric neuroimaging and can be challenging, particularly in settings without dedicated paediatric neuroradiologists. Deep learning models have recently been shown to be able to estimate myelination age in children with normal MRI, but currently lack validation for patients with myelination delay and implementation including pre-processing suitable for local imaging is not trivial. Standardized myelination scores, which have been successfully used as biomarkers for myelination in hypomyelinating diseases, rely on visual, semiquantitative scoring of myelination on routine clinical MRI and may offer an easy-to-use alternative for assessment of myelination.
