Prevalence and clinical significance of incidental findings in chest and abdominopelvic CT scans of trauma patients; A cross-sectional study.

BACKGROUND: Imaging may inadvertently reveal pathologies unrelated to their performing purpose, known as incidental findings (IF). This study aimed to assess the prevalence, clinical significance, and documentation of IFs in chest and abdominopelvic computed tomography (CT) scans of trauma patients. METHODS: This observational study was conducted at two urban level-1 trauma centers from March 2019 through April 2022. Official radiology reports of trauma patients who underwent chest and/or abdominopelvic CT scans at the emergency department (ED) were explored, and IF were extracted. Predictive factors of the presence of IFs and their documenting were investigated. RESULTS: Out of 656 chest and 658 abdominopelvic CT scans, 167 (25.37%) and 212 (32.31%) scans harbored at least one IF, respectively. Patients with IFs tended to be of higher age and female in both chest (age: 48 [IQR: 35-62] vs. 34 [IQR: 25-42.5]; female: 31.14% vs 14.66%, p < 0.001 for both) and abdominopelvic CT scans (age: 41 [IQR: 30-57.5] vs 33 [IQR: 25-43], female: 26.42% vs. 13.96%, p < 0.001 for both). As for documentation of significant IFs, only 49 of 112 chest IFs (43.8%) and 55 of 176 abdominopelvic IFs (31.3%) were documented. Investigating factors associated with documentation of clinically significant IFs, shorter length of hospital stay (1.5 (IQR: 0-4) vs. 3 (IQR: 2-8), p = 0.003), and discharging by ED physicians (documentation rate: 13.2% vs 42.6%, p < 0.001) were associated with poorer documentation of IFs only in abdominopelvic scans. CONCLUSION: CT imaging in ED trauma patients often reveals incidental findings, especially in older patients. Over 50% of these findings are clinically significant, yet they are frequently ignored and not documented. Physicians need to be more vigilant in recognizing and documenting these incidental findings and informing patients of the need for further evaluation.

Effect of Postoperative Kinesio Taping on Knee Edema, Pain, and Range of Motion After Total Knee Arthroplasty and Anterior Cruciate Ligament Reconstruction: A Systematic Review and Meta-analysis of Randomized Clinical Trials.

BACKGROUND: Kinesio taping (KT) has been shown to be clinically effective in a wide range of musculoskeletal disorders. Despite evidence supporting KT, there still needs to be more certainty regarding its clinical worthiness in managing postoperative conditions. This study aims to assess the effect of postoperative KT on knee edema, pain, and range of motion (ROM) when added to routine physiotherapy after knee surgery. METHODS: In this systematic review and meta-analysis, MEDLINE, Embase, Scopus, Web of Science, and CENTRAL databases were searched from their inception to July 2023. Randomized controlled trials (RCTs) comparing routine physiotherapy with and without KT were included. Random-effect models were used to calculate the standardized mean difference (SMD), confidence interval, and heterogeneity (I2). RESULTS: Sixteen RCTs on 842 operated knees were included. KT reduced knee edema in first week (SMD, -0.59, p < 0.001), 14th postoperative day (POD) (SMD, -0.78, p < 0.001), and 28 to 42 days postop (SMD, -0.66, p < 0.001). The KT demonstrated significant pain improvement in second week (SMD, -0.87, p < 0.001) and the fourth week (SMD, -0.53, p < 0.001). The KT groups demonstrated ROM improvement within second week (SMD, 0.69, p = 0.010) and in the 28th POD (SMD, 0.89, p = 0.009). Subgroup analysis demonstrated minimal heterogeneity in anterior cruciate ligament reconstruction (ACLR) cases. However, it did not show significant superiority regarding ankle, calf, or thigh edema and Lysholm scale. CONCLUSION: This study suggests that adding KT to routine postoperative physiotherapy reduces pain and knee edema after total knee arthroplasty or ACLR. Low to very low certainty of evidence for all outcomes and the limited number of studies emphasize the need for more high-quality primary studies to explore the optimal method of KT application and its effectiveness in specific knee surgeries.

Clinical decision rules in predicting computed tomography scan findings and need for neurosurgical intervention in mild traumatic brain injury: a prospective observational study.

PURPOSE: In this study, we will compare the diagnostic values of head CT decision rules in predicting the findings of CT scans in a prospective multicenter study in university emergency departments in Iran. METHODS: The primary outcome was any traumatic lesion findings in brain CT scans, and the secondary outcomes were death, the need for mechanical ventilation, and neurosurgical intervention. Decision rules including the Canadian CT Head Rule (CCHR), New Orleans Criteria (NOC), National Institute for Health and Clinical Excellence (NICE), National Emergency X-Radiography Utilization Study (NEXUS), and Neurotraumatology Committee of the World Federation of Neurosurgical Societies (NCWFNS) were compared for the main outcomes. RESULTS: In total, 434 mild TBI patients were enrolled in the study. The NCWFNS had the highest sensitivity (91.14%) and the lowest specificity (39.42%) for predicting abnormal finding in CT scan compared to other models. While the NICE obtained the lowest sensitivity (79.75%), it was associated with the highest specificity (66.67%). All model performances were improved when administered to predict neurosurgical intervention among patients with GCS 13-15. NEXUS (AUC 0.862, 95% CI 0.799-0.924) and NCWFNS (AUC 0.813, 95% CI 0.723-0.903) had the best performance among all evaluated models. CONCLUSION: The NCWFNS and the NEXUS decision rules performed better than the CCHR and NICE guidelines for predicting any lesion in the CT imaging and neurosurgical intervention among patients with mTBI with GCS 13-15. For a subset of mTBI patients with GCS 15, the NOC criteria have higher sensitivity for abnormal CT imaging, but lower specificity and more requested CTs.

Soluble Suppression of Tumorigenicity-2 as a Candidate Prognostic Marker for Stroke: A Systematic Review.

Background: Risk stratification of patients for incidence of stroke and its outcomes can aid in decision-making regarding treatment options and rehabilitative care. We systematically reviewed the literature to provide comprehensive evidence for the value of serum soluble suppression of tumorigenicity-2 (sST-2) in the prediction of stroke incidence and the evaluation of post-stroke outcomes. Methods: The Medline, Scopus, Web of Science, and Embase databases were searched until the end of August 2022 for studies investigating the value of serum sST-2 in the prediction of stroke incidence and post-stroke outcomes. Results: Nineteen articles were included. The articles reported conflicting results on the predictive value of sST-2 measurement in the incidence of stroke. Studies investigating the value of sST-2 measurement for the prognosis of post-stroke outcomes have reported positive associations between sST-2 levels and post-stroke mortality, composite adverse events, major disability, cerebral-cardiac syndrome, and cognitive impairment. Conclusions: Although some studies have reported a predictive value of serum sST-2 measurement in the incidence of stroke, a clear consensus has yet to be reached because of discrepancies in the results. As for the prognosis of post-stroke outcomes, sST-2 may be a predictor of mortality, composite adverse events, and major disability after stroke. Overall, more well-designed prospective cohort studies are needed to reach a more decisive conclusion on the value of sST-2 measurement for the prediction of stroke and its outcomes and to determine optimal cutoffs.
