Artificial intelligence (AI)-assisted chest computer tomography (CT) insights: a study on intensive care unit (ICU) admittance trends in 78 coronavirus disease 2019 (COVID-19) patients.

Background: The global coronavirus disease 2019 (COVID-19) pandemic has posed substantial challenges for healthcare systems, notably the increased demand for chest computed tomography (CT) scans, which lack automated analysis. Our study addresses this by utilizing artificial intelligence-supported automated computer analysis to investigate lung involvement distribution and extent in COVID-19 patients. Additionally, we explore the association between lung involvement and intensive care unit (ICU) admission, while also comparing computer analysis performance with expert radiologists' assessments. Methods: A total of 81 patients from an open-source COVID database with confirmed COVID-19 infection were included in the study. Three patients were excluded. Lung involvement was assessed in 78 patients using CT scans, and the extent of infiltration and collapse was quantified across various lung lobes and regions. The associations between lung involvement and ICU admission were analysed. Additionally, the computer analysis of COVID-19 involvement was compared against a human rating provided by radiological experts. Results: The results showed a higher degree of infiltration and collapse in the lower lobes compared to the upper lobes (P<0.05). No significant difference was detected in the COVID-19-related involvement of the left and right lower lobes. The right middle lobe demonstrated lower involvement compared to the right lower lobes (P<0.05). When examining the regions, significantly more COVID-19 involvement was found when comparing the posterior vs. the anterior halves and the lower vs. the upper half of the lungs. Patients, who required ICU admission during their treatment exhibited significantly higher COVID-19 involvement in their lung parenchyma according to computer analysis, compared to patients who remained in general wards. Patients with more than 40% COVID-19 involvement were almost exclusively treated in intensive care. A high correlation was observed between computer detection of COVID-19 affections and the rating by radiological experts. Conclusions: The findings suggest that the extent of lung involvement, particularly in the lower lobes, dorsal lungs, and lower half of the lungs, may be associated with the need for ICU admission in patients with COVID-19. Computer analysis showed a high correlation with expert rating, highlighting its potential utility in clinical settings for assessing lung involvement. This information may help guide clinical decision-making and resource allocation during ongoing or future pandemics. Further studies with larger sample sizes are warranted to validate these findings.

From Voxels to Prognosis: AI-Driven Quantitative Chest CT Analysis Forecasts ICU Requirements in 78 COVID-19 Cases.

Background: The aim of the current study was to investigate the distribution and extent of lung involvement in patients with COVID-19 with AI-supported, automated computer analysis and to assess the relationship between lung involvement and the need for intensive care unit (ICU) admission. A secondary aim was to compare the performance of computer analysis with the judgment of radiological experts. Methods: A total of 81 patients from an open-source COVID database with confirmed COVID-19 infection were included in the study. Three patients were excluded. Lung involvement was assessed in 78 patients using computed tomography (CT) scans, and the extent of infiltration and collapse was quantified across various lung lobes and regions.

Operative Stabilization of Chest Wall Trauma: Single-Center Report of Initial Management and Long-Term Outcome.

BACKGROUND: Conservative treatment of even severe thoracic trauma including flail chest was traditionally the standard of care. Recently, we reported possible benefits of surgical chest wall stabilization in accordance with other groups. The aim of this study was to critically review our indications and results of internal fixation of rib fractures in the long-term course. METHODS: We retrospectively analyzed the data of a consecutive series of patients with internal rib fracture fixation at our institution from 8/2009 until 12/2014, and we retrospectively studied the late outcome through clinical examination or personal interview. RESULTS: From 1398 patients, 235 sustained a severe thoracic trauma (AIS ≥3). In 23 of these patients, 88 internal rib fixations were performed using the MatrixRIB® system. The median age of these operated patients was 56 years [interquartile range (IQR) 49-63] with a median ISS of 21 [IQR 16-29]. From 18 local resident patients, follow-up was obtained after an average time period of 27.6 (12-68) months. Most of these patients were free of pain and had no limitations in their daily routine. Out of all implants, 5 splint tips perforated the ribs in the postoperative course, but all patients remained clinically asymptomatic. Plate osteosynthesis showed no loss of reduction in the postoperative course. No cases of hardware prominence, wound infection or non-union occurred. CONCLUSIONS: In our carefully selected thoracic trauma patients, locked plate rib fixation seemed to be safe and beneficial not only in the early posttraumatic course, but also after months and years, patients remain asymptomatic and complete recovery as a rule.
