de assessment, performance of imaging ranged widely. However, prostate-specific membrane antigen positron emission tomography/computed tomography showed favorable results for the detection of distant metastases.
We performed a systematic review of currently available imaging modalities to stage newly diagnosed prostate cancer. With respect to local tumor and lymph node assessment, performance of imaging ranged widely. However, prostate-specific membrane antigen positron emission tomography/computed tomography showed favorable results for the detection of distant metastases.
Prediction of vesicoureteral reflux (VUR) prognosis and decision for treatment are usually made according to the reflux grading classification. But the management of VUR is still controversial since there are difficulties in distinguishing reflux grade due to inter- and intra-observer variations. Previous studies have demonstrated that the distal ureteral diameter ratio (UDR) on voiding cystourethrography (VCUG) may be more predictive for clinical prognosis than reflux grade. We aimed to predict the success of endoscopic injection in primary VUR by creating new models that include other additional parameters (timing of reflux, delayed post-voiding contrast drainage of the upper urinary tract) as well as UDR.

A total of 200 patients aged 2-15 years with primary VUR undergoing endoscopic injection were retrospectively evaluated. Demographic and clinical data for a total of 248 renal units were recorded. click here Besides reflux grade and laterality, distal ureteral diameter, UDR, timing of reflux [early filling, latemary VUR rather than upper urinary tract dilatation since ureterovesical junction anatomy plays a more important role in primary VUR pathophysiology. Studies investigating new prediction models on this topic have recently become more popular. However, a consensus has not yet been achieved.

We consider that UDR level, the timing of reflux and delayed upper tract drainage on VCUG may be more predictive parameters of endoscopic injection success compared with reflux grade, and could facilitate selecting the best candidates for surgery.

This association has been particularly strong for cerebral small vessel disease. Significant findings have emerged from studies ranging from case reports, small case series, and larger cohort investigations. The latter show a relationship between declining renal function, microvascular disease, and cognitive impairment. One troubling aspect has been the relative paucity of mechanistic investigations addressing the CKD-cerebrovascular disease linkage. Nevertheless, mechanistic observations have begun to emerge, showing cerebral microhemorrhage development in animal models of CKD independent of hypertension, an important co-morbidity in clinical studies. Initial cell culture studies show endothelial monolayer disruption by CKD serum, consistent with blood-brain barrier injury. It is noteworthy that CKD serum is known to contain multiple plausible mediators of microvascular injury. Further studies are on the horizon to address the critical question of potential linkage of renal dysfunction with vascular cognitive impairment.
Observation of the entire stomach during esophagogastroduodenoscopy (EGD) is important; however, there is a lack of effective evaluation tools.

To develop an artificial intelligence (AI)-assisted EGD system able to automatically monitor blind spots in real-time.

An AI-based system, called the Intelligent Detection Endoscopic Assistant (IDEA), was developed using a deep convolutional neural network (DCNN) and long short-term memory (LSTM). The performance of IDEA for recognition of gastric sites in images and videos was evaluated. Primary outcomes included diagnostic accuracy, sensitivity, and specificity.

A total of 170,297 images and 5779 endoscopic videos were collected to develop the system. As the test group, 3100 EGD images were acquired to evaluate the performance of DCNN in recognition of gastric sites in images. The sensitivity, specificity, and accuracy of DCNN were determined as 97.18%,99.91%, and 99.83%, respectively. To assess the performance of IDEA in recognition of gastric sites in EGD videos, 129 videos were used as the test group. The sensitivity, specificity, and accuracy of IDEA were 96.29%,93.32%, and 95.30%, respectively.

IDEA achieved high accuracy for recognition of gastric sites in real-time. The system can be applied as a powerful assistant tool for monitoring blind spots during EGD.

To compare [¹¹C] choline PET/CT findings between patients with cirrhosis and normal liver controls.

Included 11 patients with cirrhosis and 14 controls. All underwent a dynamic [11C] choline PET/CT. The maximal standard uptake values (SUVmax), the area under the curve (AUC) and kinetic parameters (K1 and K2), clinical and laboratory data, were compared between groups.

Patients mean age was 68.4 ± 10.7 and controls, 69.7 ± 7.3 years. Mean SUVmax was higher in patients than controls (right lobe, 10.06 ± 12 vs. 6.3 ± 1.6, P = 0.011; left lobe, 8.6 ± 11.6 vs. 5.4 ± 0.9, P = 0.024; spleen 17.99 ± 27.8 vs. 13.4 ± 2.6, P = 0.027; kidney, 35.9 ± 59.5 vs. 19.3 ± 4.8, P = 0.025) and also AUC values (right lobe, 13,538 ± 20,020 vs. 8427.3 ± 1557.9, P = 0.026; left lobe 12,304 ± 18,871 vs. 6878.9 ± 1294.3, P = 0.024; spleen, 12,875 ± 17,930 vs. 8263.9 ± 1279.2, P = 0.023; kidney, 24,623 ± 36,025 vs. 13,667 ± 3873.9, P = 0.032). No difference in kinetic parameters was found. No correlations between severity of clinical signs and imaging-derived parametric data were found among patients with cirrhosis.
