Enhanced accuracy with Segmentation of Colorectal Polyp using NanoNetB, and Conditional Random Field Test-Time Augmentation.

Colonoscopy is a reliable diagnostic method to detect colorectal polyps early on and prevent colorectal cancer. The current examination techniques face a significant challenge of high missed rates, resulting in numerous undetected polyps and irregularities. Automated and real-time segmentation methods can help endoscopists to segment the shape and location of polyps from colonoscopy images in order to facilitate clinician's timely diagnosis and interventions.

Classification of white blood cells (leucocytes) from blood smear imagery using machine and deep learning models: A global scoping review.

Machine learning (ML) and deep learning (DL) models are being increasingly employed for medical imagery analyses, with both approaches used to enhance the accuracy of classification/prediction in the diagnoses of various cancers, tumors and bloodborne diseases. To date however, no review of these techniques and their application(s) within the domain of white blood cell (WBC) classification in blood smear images has been undertaken, representing a notable knowledge gap with respect to model selection and comparison. Accordingly, the current study sought to comprehensively identify, explore and contrast ML and DL methods for classifying WBCs.

Multi-objective regression test suite optimization using three variants of adaptive neuro fuzzy inference system.

In the process of software development, regression testing is one of the major activities that is done after making modifications in the current system or whenever a software system evolves. But, the test suite size increases with the addition of new test cases and it becomes in-efficient because of the occurrence of redundant, broken, and obsolete test cases. For that reason, it results in additional time and budget to run all these test cases.

Neurotransmission cognitive theory: A novel approach for non-invasive brain stimulation using mechanical vibrations for the rehabilitation of neurological patients.

Patients suffering from neurological disorders require not only the treatment but also the rehabilitation to have their productive role in society. With the advent of modern technology and neuroscience techniques, different treatments are proposed and tested clinically. We propose a therapeutic and interventional noninvasive brain stimulation method that applies mechanical vibrations to different nerve points of the body to activate the stimuli.

Detection of Paracetamol as substrate of the gut microbiome.

Gut microbiome, a new organ; represent targets to alter pharmacokinetics of orally administered drugs. Recently, in vitro trials endorsed the idea that orally administered drugs interact and some of their quantity may be taken up by normal microbiome during transit through gut. Such transport mechanisms in microbiome may compete for drug with the host itself.

Outcomes of Extracorporeal Membrane Oxygenation Support for Complex High-Risk Elective Percutaneous Coronary Interventions: A Single-Center Experience and Review of the Literature.

Objectives: Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is most commonly used in patients with cardiac arrest and cardiogenic shock. There are limited data on the use of VA-ECMO for elective, high-risk percutaneous coronary intervention (PCI). We examined the in-hospital and mid-term clinical outcomes in patients undergoing complex, high-risk PCI with VA-ECMO support.

Incidence, predictors, management and outcomes of coronary perforations.

Objectives: We examined the contemporary incidence, types, predictors, angiographic characteristics, management and outcomes of coronary perforation.

Background: Coronary perforation is a rare, but important, complication of percutaneous coronary intervention (PCI). There is lack of data on perforations stratified as large and distal vessel perforations.

Use of chronic total occlusion percutaneous coronary intervention techniques for treating acute vessel closure.

Acute vessel closure due to dissection is a known complication of percutaneous coronary intervention and can be challenging to treat, especially if guidewire position is lost. Re-entering into the distal true lumen is commonly done during chronic total occlusion interventions, as part of antegrade dissection strategies. We report two cases of acute vessel closure and guidewire position loss in which the Stingray LP system was successfully used to advance a guidewire into the distal true lumen and recanalize the occluded vessel.

Analysis of PCG signals using quality assessment and homomorphic filters for localization and classification of heart sounds.

Background And Objective: Accurate localization of heart beats in phonocardiogram (PCG) signal is very crucial for correct segmentation and classification of heart sounds into S1 and S2. This task becomes challenging due to inclusion of noise in acquisition process owing to number of different factors. In this paper we propose a system for heart sound localization and classification into S1 and S2.

Safety and utility of dobutamine and pressure wire use in the hemodynamic assessment of low-flow, low-gradient aortic stenosis with reduced left ventricular ejection fraction.

Background: The ACC/AHA guidelines recommend low-dose dobutamine challenge for hemodynamic assessment of the severity of AS in patients with low flow, low gradient aortic stenosis with reduced ejection fraction (EF) (LFLG-AS; stage D2). Inherent pitfalls of echocardiography could result in inaccurate aortic valve areas (AVA), which have downstream prognostic implications. Data on the safety and efficacy of coronary pressure wire and fluid-filled catheter use for low dose dobutamine infusion is sparse.

Etiology of gastrointestinal bleeding in patients on dual antiplatelet therapy.

Objective: Dual antiplatelet therapy (DAPT) is associated with an increased risk of gastrointestinal (GI) bleeding and is thought to cause upper gastrointestinal bleeding (UGIB). However, recent reports indicate that the incidence of lower gastrointestinal bleeding (LGIB) in patients on DAPT may be increasing. We aimed to compare the endoscopic findings and etiology of GI bleeding between patients on DAPT compared with those not on DAPT.

Hybrid Features and Mediods Classification based Robust Segmentation of Blood Vessels.

Retinal blood vessels are the source to provide oxygen and nutrition to retina and any change in the normal structure may lead to different retinal abnormalities. Automated detection of vascular structure is very important while designing a computer aided diagnostic system for retinal diseases. Most popular methods for vessel segmentation are based on matched filters and Gabor wavelets which give good response against blood vessels.
