FocusUNet: Pioneering dual attention with gated U-Net for colonoscopic polyp segmentation.
Comput Biol Med
January 2025
Department of EECE, Military Institute of Science and Technology (MIST), Mirpur Cantonment, Dhaka, 1216, Bangladesh. Electronic address:
The detection and excision of colorectal polyps, precursors to colorectal cancer (CRC), can improve survival rates by up to 90%. Automated polyp segmentation in colonoscopy images expedites diagnosis and aids in the precise identification of adenomatous polyps, thus mitigating the burden of manual image analysis. This study introduces FocusUNet, an innovative bi-level nested U-structure integrated with a dual-attention mechanism.

In coronary artery bypass grafting (CABG) on pump, achieving optimal visualization is critical for surgical precision and safety. The use of blowers to clear the CABG anastomosis poses risks, including the formation of micro-embolic gas bubbles, which can be insidious and increase the risk of cerebral or myocardial complications. This retrospective study compares the effectiveness of the use of irrigation mist and CO versus a direct CO blower without irrigation in terms of visualization, postoperative fibrillation, and micro-embolic gas activity.

Article Synopsis
- Hydrofluoric and nitric acids are highly corrosive and can cause chemical pneumonia when inhaled, leading to serious respiratory issues and requiring supportive treatment to manage symptoms.* -
- The case study discusses three individuals who suffered from chemical pneumonia after a workplace accident involving a mixture of these acids, highlighting the need for emergency treatments like oxygenation.* -
- The report emphasizes the rarity of lung damage from hydrogen fluoride exposure, suggesting that improved safety measures in workplaces and awareness among medical professionals are essential to prevent severe health consequences.*
Public perspectives on the benefits and harms of lung cancer screening: A systematic review and mixed-method integrative synthesis.

Article Synopsis
- - The study aimed to understand how target populations perceive the benefits and harms of lung cancer screening using low dose computed tomography, citing a lack of knowledge in this area.
- - A systematic review analyzed 49 studies and found that while many people viewed screening positively for early detection and reassurance, concerns about radiation and screening anxiety, particularly among current smokers and low-income individuals, were also prevalent.
- - The study concludes that targeted populations often justify physical harms of screening for the sake of early detection, highlighting the need for screening programs to communicate benefits clearly and design them in a non-stigmatizing manner while considering equity.
Distribution of oil mist particles and air quality improvement in the working area of the cutting workshop.

The oil mist particles cyclically emitted during the cutting process are a serious health hazard for workers in machine plants. Affected by emission parameters and seasonal factors, the dynamic distribution of oil mist particles in the workers' breathing zone is not yet clear, and suitable ventilation optimization is yet to be proposed. This paper investigates the dynamic distribution of oil mist particles in the workers' breathing zone and ventilation optimization by numerical simulation.
