BACKGROUND: Currently there is no effective treatment for neonatal stroke, an acute neurologic syndrome with sequelae, due to focal ischemic, thrombotic, or hemorrhagic event occurring in the perinatal period. VCE-004.8, an aminoquinone exhibiting activity on CB2 and PPARγ receptors, is neuroprotective in adult mice models of acute and chronic brain damaging conditions. We hereby aimed to study VCE-004.8 neuroprotection in a rat model of neonatal stroke. METHODS: 7-day-old (P7) Wistar rats of both sexes were submitted to Middle Cerebral Artery Occlusion (MCAO), receiving i...

OBJECTIVE: This study aimed to evaluate the use of video capsule endoscopy (VCE) in patients with obscure gastrointestinal bleeding (OGIB), compare cases of overt and occult OGIB, assess the rates of balloon-assisted enteroscopy (BAE) interventions and rebleeding, and identify predictive markers of positive VCE findings. METHODS: Medical records of 430 patients who underwent VCE for OGIB between 2004 and 2022 were analyzed. Occult OGIB was defined as IDA or positive fecal occult blood, whereas overt OGIB was defined as clinically imperceptible bleeding...

As a core component of power conversion systems, insulated gate bipolar transistor (IGBT) modules continually suffer from severe thermal damage caused by temperature swings and shear stress, resulting in fatigue failure. Bond wires falling off is one of the failure modes of IGBT modules. Given that the number of fallen-off bond wires is a significant parameter to evaluate the health status of the IGBT modules, this paper proposes an online identification model to recognize the number of fallen-off bond wires during normal operation...

In 2021, identified VCEs were emailed an anonymous survey that was based on past research on roles and responsibilities of VCEs. Through qualitative and quantitative questions, the survey assessed demographic characteristics, actual and expected work responsibilities, work satisfaction, and work barriers during time spent in the VCE role...

BACKGROUND AND AIM: Gastrointestinal (GI) bleeding or malabsorption represents the most frequent aetiologies of iron deficiency anemia (IDA). The cause of IDA remains undetermined in ~10% to 20% of patients undergoing upper and lower GI endoscopies. In this scenario, a small bowel examination with videocapsule endoscopy (VCE) is recommended. We performed a systematic review with meta-analysis to evaluate the diagnostic yield of VCE in patients with IDA without overt bleeding, assessing the prevalence of either any lesion or lesions at high potential of bleeding...

PURPOSE: Deep inspiration breath hold (DIBH) is an effective technique to spare the heart in treating left-sided breast cancer. Surface-guided radiation therapy (SGRT) is increasingly applied in DIBH setup and motion monitoring. Patient-specific breathing behavior, either thoracically driven or abdominally driven (A-DIBH), should be unaltered, online identified, and monitored accordingly to ensure reproducible heart-sparing treatment. METHODS AND MATERIALS: Sixty patients with left-sided breast cancer treated with SGRT were analyzed: 20 A-DIBH patients with vertical chest elevation (VCE ≤ 5 mm) were prospectively identified, and 40 control patients were retrospectively and randomly selected for comparison...

BACKGROUND: Small bowel disorders present a diagnostic challenge due to the limited accessibility of the small intestine. Accurate diagnosis is made with the aid of specific procedures, like capsule endoscopy or double-ballon enteroscopy, but they are not usually solicited and not widely accessible. This study aims to assess and compare the diagnostic effectiveness of enteroscopy and video capsule endoscopy (VCE) when combined with artificial intelligence (AI) algorithms for the automatic detection of small bowel diseases...

BACKGROUND: Current guidelines strongly recommend the use of validated classifications to support optical diagnosis of lesions with advanced endoscopic imaging in the lower gastrointestinal tract. However, the optimal strategy in inflammatory bowel disease (IBD) is still a matter of debate. OBJECTIVES: To analyze the accuracy of endoscopic classifications or single predictors for in vivo lesion characterization during endoscopic surveillance of IBD with advanced endoscopic imaging...

The diagnostic work-up in iron deficiency anaemia (IDA) patients can be challenging when bleedings or malabsorption are not clinically manifest. Lesions on the small bowel mucosa may cause IDA. We evaluated the prevalence of lesions on the small bowel mucosa detected at Videocapsule Endoscopy (VCE) in IDA patients following negative upper and lower endoscopies. Clinical and endoscopic data collected in 5 centres were retrieved. Lesions with a high bleeding potential (P2) were computed, and predictive factors investigated at multivariate analysis...

The management of pediatric Peutz-Jeghers Syndrome (PJS) focuses on the prevention of intussusception complicating small intestinal (SI) polyposis. This hinges on the accurate appraisal of the polyp burden to tailor therapeutic interventions. Video Capsule Endoscopy (VCE) is an established tool to study SI polyps in children, but an in-depth characterization of polyp burden in this population is lacking. Methods: We performed a retrospective longitudinal cross-sectional analysis of VCE studies in pediatric PJS patients at our institution (CMKC) from 2010 to 2020...

Video capsule endoscopy (VCE) is increasingly used to decrease discomfort among patients owing to its small size. However, VCE has a major drawback of not having narrow band imaging (NBI) functionality. The current VCE has the traditional white light imaging (WLI) only, which has poor performance in the computer-aided detection (CAD) of different types of cancer compared to NBI. Specific cancers, such as esophageal cancer (EC), do not exhibit any early biomarkers, making their early detection difficult. In most cases, the symptoms are unnoticeable, and EC is diagnosed only in later stages, making its 5-year survival rate below 20% on average...
