93-0.94, lateral meniscus F1 scores 0.86-0.88). When these algorithms were evaluated on arthroscopy reports, despite never training on arthroscopy reports, performance was similar, though higher with model ensembling (medial meniscus F1 score 0.97, lateral meniscus F1 score 0.99). However, ensembling did not improve performance on knee MRI reports. In the radiology-arthroscopy test set, the ensembled NLP models were able to detect mismatches between MRI and arthroscopy reports with sensitivity 79% and specificity 87%.

Radiology-arthroscopy correlation can be automated for knee meniscal tears using NLP algorithms, which shows promise for education and quality improvement.

COVID-19 commonly presents with upper respiratory symptoms; however, studies have shown that SARS-CoV-2 infection affects multiple organ systems. selleckchem Here, we review the pathophysiology and imaging characteristics of SARS-CoV-2 infection in organ systems throughout the body and explore commonalities.

Familiarity with the underlying pathophysiology and imaging characteristics is essential for the radiologist to recognize these findings in patients with COVID-19 infection. Though pulmonary findings are the most prevalent presentation, COVID-19 may have multiple manifestations and recognition of the extrapulmonary manifestations is especially important because of the potential serious and long-term effects of COVID-19 on multiple organ systems.

The coronavirus disease of 2019 (COVID-19) due to SARS-CoV-2 infection has been found to cause an increased risk of venous thrombo-embolism (VTE). The aims of the study were to determine the frequency of VTE in critically ill patients with COVID-19 and its correlation with D dimer levels and pharmacological prophylaxis.

This was a cohort study of critically ill patients due to COVID-19. All patients admitted to the intensive care unit on the same day of April 2020 were selected, regardless of length of stay, and a single bilateral venous duplex ultrasound in the lower extremities was performed up to 72 hours later. Pulmonary embolism (PE) was diagnosed by computed tomography angiography. Asymptomatic and symptomatic VTE were registered, including pre-screening in hospital VTE. Characteristics of patients, blood test results, doses of thromboprophylaxis received, VTE events, and mortality after seven day follow up were recorded.

A total of 230 critically ill patients were studied. The median intensive cath a low risk of bleeding.

Patients with severe COVID-19 infection are at high risk of VTE, and further new symptomatic VTE events and recurrence can occur despite anticoagulation. The prophylactic anticoagulant dose may need to be increased in patients with a low risk of bleeding.

Vascular limb salvage services are recommended by the Global Vascular Guidelines to help improve outcomes for patients with chronic limb-threatening ischaemia (CLTI), although their description within the literature is limited. This study reports the 12 month outcomes for an outpatient based vascular limb salvage (VaLS) clinic.

An analysis of a prospectively maintained database, involving all consecutive patients diagnosed with CLTI within the VaLS clinic from February 2018-February 2019, was undertaken. Data were compared with two comparator cohorts, identified from coding data 1) patients managed prior to the clinic, between May 2017 and February 2018 (Pre-Clinic [PC]); and 2) patients managed outside of clinic, between February 2018 and February 2019 (Alternative Pathways [AP]). Freedom from major amputation at 12 months was the primary outcome. Kaplan-Meier plots and adjusted Cox's proportional hazard models (aHR) were used to compare outcomes.

Five hundred and sixty-six patients (VaLS 158, AP 173, atory setting. Further evaluation is required to assess longer term outcomes.Gadolinium-enhanced magnetic resonance angiography (MRA) and computed tomography angiography (CTA) are commonly used for diagnosing renal arterial stenosis (RAS); however, the diagnostic value is yet controversial. The aim of the study was to evaluate the diagnostic values of both methods. Electronic databases, including PubMed, Embase, and the Cochrane Library, were searched for studies, since inception until October 2017. A total of four articles involving 486 subjects were included in the analysis. The summary of sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), and area under the receiver operating characteristic (ROC) (AUC) were 0.70, 0.82, 14.54, 0.29, 63.80, and 0.81 for MRA-based diagnosis of RAS, respectively. The pooled sensitivity, specificity, PLR, NLR, DOR, and AUC for CTA detecting RAS were 0.73, 0.96, 13.04, 0.29, 71.99, and 0.93, respectively. Gadolinium-enhanced MRA and CTA provide a satisfactory diagnostic accuracy, thereby playing a critical role in the diagnosis of RAS.

The nature of susceptibility to condylar resorption after orthognathic surgery can be different between skeletal Class II and Class III populations, which was addressed by few in the past. The aim of the present study was to use cone-beam computed tomographic (CBCT) images to investigate the displacement and morphological changes of temporomandibular joints (TMJs) in patients received orthodontic treatment combined with orthognathic surgery.

Both Class III (n=34) and Class II (n=17) patients were compared through overall and regional superimpositions of the initial and posttreatment CBCTs. Two-sample t-test was used to identify significance between group differences. Pearson's correlation coefficient was used to address changes of TMJ and the amount of setback or advancement.

The axial ramal angle increased significantly in Class III group and decreased in Class II groups after orthognathic surgery (p<FDR_p). For condylar dimensions, significant widths and lengths reductions were noted only in Class II group.
