COMP Report: CPQR technical quality control guidelines for use of positron emission tomography/computed tomography in radiation treatment planning

open access: yesJournal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Positron emission tomography with x‐ray computed tomography (PET/CT) is increasingly being utilized for radiation treatment planning (RTP). Accurate delivery of RT therefore depends on quality PET/CT data. This study covers quality control (QC) procedures required for PET/CT for diagnostic imaging and incremental QC required for RTP.

Evaluation of intrafraction couch shifts for proton treatment delivery in head‐and‐neck cancer patients: Toward optimal imaging frequency

open access: yesJournal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Purpose Treatment planning for head‐and‐neck (H&N) cancer, in particular oropharynx, nasopharynx, and paranasal sinus cases, at our center requires noncoplanar proton beams due to the complexity of the anatomy and target location. Targeting accuracy for all beams is carefully evaluated by using image guidance before delivering proton beam ...

Phenotypic continuum of NFU1‐related disorders

open access: yesAnnals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 2025-2035, December 2022., 2022
Abstract Bi‐allelic variants in Iron–Sulfur Cluster Scaffold (NFU1) have previously been associated with multiple mitochondrial dysfunctions syndrome 1 (MMDS1) characterized by early‐onset rapidly fatal leukoencephalopathy. We report 19 affected individuals from 10 independent families with ultra‐rare bi‐allelic NFU1 missense variants associated with a

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

open access: yesAnnals 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.

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

open access: yesAnnals 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.

Frailty and surgical outcomes in gastrointestinal cancer: Integration of geriatric assessment and prehabilitation into surgical practice for vulnerable patients

open access: yesAnnals of Gastroenterological Surgery, Volume 7, Issue 1, Page 27-41, January 2023., 2023
Accumulating evidence demonstrates that the integration of preoperative geriatric assessment and prehabilitation for frail patients into clinical practice may improve perioperative and long‐term outcomes in patients with gastrointestinal cancer. We proposed an example for the integration of older patients‐specific care into treatment strategies for ...

Differences in prognosis and underuse of adjuvant chemotherapy between elderly and non‐elderly patients in stage III colorectal cancer

open access: yesAnnals of Gastroenterological Surgery, Volume 7, Issue 1, Page 91-101, January 2023., 2023
This study analyzed data from consecutive patients with stage III colorectal cancer following curative resection and examined the reason for not introducing adjuvant chemotherapy (AC) and the differences in prognosis between completed and incomplete AC in elderly and non‐elderly patients.

Pulsed Laser Deposition of a PBN:65 Morphotropic Phase Boundary Thin Film with Large Electrostriction [PDF]

open access: yesCentral Eur.J.Phys. 3 (2005) 178-185, 2005
We deposited epitaxial thin films of Morphotropic Phase Boundary (MPB) Pb0.65Ba0.35Nb2O6 (PBN:65) on MgO substrates using pulsed laser deposition. Afterwards, a novel transmission optical experiment was developed to measure the electric field-induced bending angle of the thin film sample using a divergent incident light. From which the electric field-
