Purpose: This article introduces a novel deep learning approach to substantially improve the accuracy of colon segmentation even with limited data annotation, which enhances the overall effectiveness of the CT colonography pipeline in clinical settings.

Methods: The proposed approach integrates 3D contextual information via guided sequential episodic training in which a query CT slice is segmented by exploiting its previous labeled CT slice (i.e.

Background: Polycystic ovary syndrome (PCOS) represents a multifaceted endocrine, reproductive, and metabolic disorder characterized by hyperandrogenism and hyperinsulinemia-induced insulin resistance (IR). Recent studies reported that the etiology of PCOS is likely correlated with genes involved in steriodogenesis, IR and glucose metabolism. Among the candidate genes in insulin signaling pathways, RAB5B, a small GTPase involved in vesicle trafficking, significantly impacts cellular pathways in ovarian follicular cells, leading to clinical and endocrine changes among women with PCOS.

Intestinal cell death is a defining feature of Crohn's disease (CD), a major form of inflammatory bowel disease. The focus on this aspect of enteric inflammation has mainly been on epithelial cells, while other cell types such as stromal and myeloid cells have received less attention. Hypothesising that decreased macrophage viability in an oxidative environment could be a contributing factor to the pathophysiology of CD, we found that monocyte-derived macrophages from individuals with active CD (but not those in clinical disease remission) have increased sensitivity to cell death induced by HO.

The disruption of the intestinal epithelial barrier leads to increased intestinal permeability (IP), allowing endotoxins and pathogens to enter the bloodstream contributing to chronic inflammation. Western diets are associated with increased IP, while diets rich in polyphenols, fiber, and omega-3 fats are linked to decreased IP. The relationship between diet, disease activity, and IP in ulcerative colitis (UC) is poorly understood.

Pain hyperacusis, also known as noxacusis, causes physical pain in response to sounds that do not bother most people. How sound causes excruciating pain that can last for weeks or months is not well understood, resulting in a lack of effective treatments. To gain insight into the underlying mechanisms of the condition, 32 adults attended a virtual focus group to describe their sound-induced pain.

Article Synopsis
  • The study investigates the incidence of blood transfusions in patients undergoing coronary artery bypass grafting (CABG) using acute normovolemic haemodilution (ANH) over six months.
  • In a cohort of 50 patients, 44% required allogeneic blood transfusions perioperatively, with notable intraoperative and ICU transfusion rates associated with lower haemoglobin levels during surgery and longer surgical times.
  • The findings suggest that managing intraoperative conditions effectively may help reduce the need for blood transfusions and minimize potential postoperative complications.

Aim: The goal of our research is to assess the olfactory fossa anatomical variation through Keros and Yenigun classification by computed tomography (CT) scan of paranasal sinuses (PNS), as in order for surgeons to prevent major complications, they must be familiar with its variations in anatomy during functional endoscopic sinus surgery (FESS) related to anterior ethmoidal artery injury, as its course varies with depth and length of the olfactory fossa.

Methods: At Karachi's Dow University of Health Sciences (DUHS), retrospective research was carried out. From anterior to posterior, sequential coronal and axial pictures were examined, and the existence and location of further anatomical characteristics were documented.

Respiratory disorders are commonly regarded as complex disorders to diagnose due to their multi-factorial nature, encompassing the interplay between hereditary variables, comorbidities, environmental exposures, and therapies, among other contributing factors. This study presents a Clinical Decision Support System (CDSS) for the early detection of respiratory disorders using a one-dimensional convolutional neural network (1D-CNN) model. The ICBHI 2017 Breathing Sound Database, which contains samples of different breathing sounds, was used in this research.

  • The study investigates the challenges and complications associated with Transcatheter Aortic Valve Implantation (TAVI) in elderly patients, often with multiple health issues, emphasizing the complexity of the procedure and post-operative care.
  • It analyzed the medical records of patients suffering from severe aortic stenosis who were deemed high-risk for traditional surgeries, focusing on their demographics, comorbidities, and outcomes after one year.
  • Results showed the patients had a low rate of complications, including minimal anesthesia-related issues, and outcomes comparable to leading global centers, indicating that TAVI might be a safe option for high-risk individuals.

Head and neck (HnN) cancers are among the most common cancers in the world. Proton therapy (PT) is one of the latest advancements in the treatment modalities of cancers. Proton therapy is specifically used to treat HnN cancer patients due to its less toxic effects on the surrounding critical structures.

  • The study aimed to evaluate how post-protamine neutralisation activated clotting time (ACT) influences outcomes in cardiac surgery, like chest drain output, blood transfusion needs, and ICU stay.
  • Conducted at The Aga Khan University Hospital from February to August 2023, it involved analyzing data from 101 elective cardiac surgery patients, split into two groups based on their ACT values.
  • Results showed no significant differences in postoperative outcomes or transfusion needs between the two groups, indicating that maintaining ACT close to baseline might be beneficial without requiring aggressive treatment.

Leishmaniasis is a parasitic disease, which spreads from the bite of an infected Phlebotomine fly to human hosts. The disease is characterized by a number of clinical manifestations, such as ulcerative lesions at the site of sandfly bite (cutaneous form), inflammation of mucosal membranes (mucosal leishmaniasis) or the deadly visceral form. This study was aimed to target pteridine reductase-1 (PTR1), a member of short chain dehydrogenases, which accounts for the reduction of conjugated and unconjugated pterins in Leishmania parasite.

The detection of lung nodules at their early stages may significantly enhance the survival rate and prevent progression to severe disability caused by advanced lung cancer, but it often requires manual and laborious efforts for radiologists, with limited success. To alleviate it, we propose a Multi-View Soft Attention-Based Convolutional Neural Network (MVSA-CNN) model for multi-class lung nodular classifications in three stages (benign, primary, and metastatic). Initially, patches from each nodule are extracted into three different views, each fed to our model to classify the malignancy.

In today's era of modern healthcare, the intersection between medical practices and environmental responsibility has gained significant attention. One such area of focus is the practice of anesthesia, which plays a crucial role in various surgical procedures. Anesthetics such as nitrous oxide and volatile halogenated ethers (desflurane, isoflurane, sevoflurane) are examples of medical gases that are strong greenhouse gases that contribute to global warming.

Plasmonic sensors utilizing surface plasmon resonance (SPR) have emerged as powerful tools for sensitive and label-free detection across a wide range of applications. This study introduces a new dual-core silver-coated plasmonic sensor designed to significantly enhance sensitivity and resolution, making it particularly effective for precise analyte detection in complex environments. A key innovation of this sensor lies in its dual-core architecture, which achieves the highest wavelength sensitivity reported at 30,000 nm/RIU and resolution of RIU, covering a broad refractive index (RI) range from 1.

This dataset aims to evaluate the use of multiple trait-based selection methods with multi-trait genotype-ideotype distance index (MGIDI) models to identify superior summer F1 tomato hybrids suitable for the climatic conditions of countries like Bangladesh. The dataset was generated using 14 cross combinations from a Line × Tester mating design, along with seven parental lines and two tester parents of tomatoes with diverse genetic bases and heat tolerance qualities in a randomized complete block (RCB) design. The likelihood ratio (LR) test indicated highly significant genotype effects for most of the analyzed traits.
