Bio-inspired circular soft actuators for simulating defecation process of human rectum [PDF]

Soft robots have found extensive applications in the medical field, particularly in rehabilitation exercises, assisted grasping, and artificial organs. Despite significant advancements in simulating various components of the digestive system, the rectum has been largely neglected due to societal stigma.

Deep learning segmentation of low-resolution images for prostate magnetic resonance-guided radiotherapy [PDF]

arXiv, 2023
The MR-Linac can enable real-time radiotherapy adaptation. However, real-time image acquisition is restricted to 2D to obtain sufficient spatial resolution, hindering accurate 3D segmentation. By reducing spatial resolution fast 3D imaging is feasible. Our study evaluates how much the spatial resolution of MR-images can be reduced without compromising ...

Possible role of human ribonuclease dicer in the regulation of R loops

FEBS Open Bio, EarlyView.
R loops play an important role in regulating key cellular processes such as replication, transcription, centromere stabilization, or control of telomere length. However, the unscheduled accumulation of R loops can cause many diseases, including cancer, and neurodegenerative or inflammatory disorders. Interestingly, accumulating data indicate a possible

Tumeur stromale à localisation rétro-rectale: entité macroscopique et difficultés chirurgicales

The Pan African Medical Journal, 2018
Les tumeurs stromales gastro-intestinales sont des tumeurs mésenchymateuses peu fréquentes dont la localisation rectale est extrêmement rare, et posent en pré-opératoire un problème de diagnostic et de prise en charge thérapeutique.

Une occlusion intestinale aiguë inhabituelle

The Pan African Medical Journal, 2015
L'insertion de corps étrangers intrarectal reste dans notre contexte, une curiosité et un tabou. Elle est le plus souvent volontaire par trouble du comportement, pour des fins sexuelles (érotisme ou agressions), pour auto-traiter une constipation ou pour

Enhanced dose prediction for head and neck cancer artificial intelligence‐driven radiotherapy based on transfer learning with limited training data

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Training deep learning dose prediction models for the latest cutting‐edge radiotherapy techniques, such as AI‐based nodal radiotherapy (AINRT) and Daily Adaptive AI‐based nodal radiotherapy (DA‐AINRT), is challenging due to limited data.

Laparoscopic versus open resection for stage II/III rectal cancer in obese patients: A multicenter propensity score‐based analysis of short‐ and long‐term outcomes

Annals of Gastroenterological Surgery, Volume 7, Issue 1, Page 71-80, January 2023., 2023
Kaplan‐Meier plot for relapse‐free survival (RFS) after propensity score (PS) matching. Abstract Aim Whether a laparoscopic procedure can contribute to the improvement of clinical outcomes in obese patients with stage II/III rectal cancer compared to an open procedure remains unclear.

The effect of multi‐leaf collimator leaf width on VMAT treatment plan quality

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Background The advent of volumetric modulated arc therapy (VMAT) in radiotherapy has made it one of the most commonly used techniques in clinical practice. VMAT is the delivery of intensity modulated radiation therapy (IMRT) while the gantry is in motion, and existing literature has shown it has decreased treatment delivery times and the ...

A phase II study of neoadjuvant capecitabine, oxaliplatin, and irinotecan (XELOXIRI) in patients with locally advanced rectal cancer

Annals of Gastroenterological Surgery, Volume 7, Issue 1, Page 81-90, January 2023., 2023
XELOXIRI neoadjuvant chemotherapy appears to be feasible and efficacious for patients with LARC. Although neoadjuvant XELOXIRI alone did not yield our expected pCR rate, the local recurrence rate, 3‐year DFS and measures of safety met current standards.
