Background: In some hospitals, patients hospitalized on the medical ward are mechanically ventilated due to a shortage of intensive care unit (ICU) beds..
Objective: To determine outcomes and prognostic factors of medical patients mechanically ventilated on general medical wards.
Material And Method: A prospective observational study was performed in general medical wards of a 2,000-bed tertiary care university hospital.
Results: Ninety-three consecutive medical patients who were mechanically ventilated on a general medical ward were included in the study. Overall mortality rate of patients mechanically ventilated on the general medical ward was 68.8%. Average length of stay was 22.9±28.5 days. Average cost per patient was 61,076.64±87,569.10 Thai baht. In univariate analysis, the APACHE II score of the patients who did not survive was significantly higher than the score of the patients who survived (mean APACHE II score 23.3±7.3 vs. 19.8±5.5 respectively, p = 0.02). Multivariate analysis revealed APACHE II score >22 to be the only independent predictor of death (OR 4.3, 95% CI 1.2-15.2, p = 0.02).
Conclusion: Medical patients who are mechanically ventilated on general medical wards have high mortality rate. APACHE II score is a good prognostic factor for predicting risk of death in these patients

In clinical optical molecular imaging, the need for real-time high frame rates and low excitation doses to ensure patient safety inherently increases susceptibility to detection noise. Faced with the challenge of image degradation caused by severe noise, image denoising is essential for mitigating the trade-off between acquisition cost and image quality. However, prevailing deep learning methods exhibit uncontrollable and suboptimal performance with limited interpretability, primarily due to neglecting underlying physical model and frequency information.

Background: We assessed association among household income, overall survival (OS), and cancer-specific survival (CSS) after proctectomy for rectal cancer.
Methods: Population-based cohort study included stage I-III rectal adenocarcinoma patients who underwent proctectomy (2010-2020), subdivided by household income at diagnosis [low (<$50,000), average ($50,000-74,999), above-average (≥$75,000)] and compared.
Results: Of 39,185 patients (59 % male; mean age 60.
