To synthetically evaluate the diagnostic accuracy of image features for differentiating benign from malignant gallbladder wall thickening disease with non-contrast MRI and establish the optimal diagnostic indicator. A total of 23 patients with wall thickening type gallbladder carcinoma and 61 patients with benign wall thickening disease were included. The diagnostic performance of six image features including the layered pattern on T2-weighted imaging (T2WI) and diffusion-weighted imaging (DWI) images, T2WI signal intensity, papillary growth, the apparent diffusion coefficient (ADC) value, and the lesion to liver parenchyma ratio (LLR) of gallbladder were evaluated and compared. ⋯ The AUC value of the combination (0.972) was higher than the layered pattern on DWI (0.904) and papillary growth (0.796) (P < .001). Non-contrast MRI provides several reliable indicators for differentiating benign from malignant gallbladder thickening disease. The combination of layered patterns on DWI and papillary growth is the optimal indicator.

Previous studies have reported that serum klotho and vitamin B12 levels are valuable aging-related markers. However, studies supporting the association between serum klotho and vitamin B12 levels are lacking. We investigated the association between serum klotho and vitamin B12 concentrations in adults in the United States. ⋯ In contrast, there was no significant relationship between klotho and vitamin B12 concentrations in the low eGFR group (beta = 0.012, SE = 0.019). Serum klotho concentration was significantly associated with vitamin B12 increases in US adults with high kidney function. Vitamin B12 concentration may be an important marker of klotho concentration in older adults.

The mean platelet volume-to-lymphocyte ratio (MPVLR), as a novel marker of thrombosis and inflammation, has been demonstrated to be closely linked to poor cardiovascular disease prognosis. However, the correlation between MPVLR and acute ischemic stroke (AIS) remains unclear. This study, therefore, aimed to clarify the relationship between MPVLR and the short-term prognosis of AIS. ⋯ MPVLR on admission was positively associated with stroke severity. An elevated MPVLR is an independent predictor of short-term mortality and poor outcome after AIS.

Observational Study
Analysis of surgical outcomes in 102 patients with renal cell carcinoma with venous tumor thrombus: A retrospective observational single-center study.
The aim of the study was to assess short- and long-term results following radical nephrectomy with renal vein and inferior vena cava thrombectomy in patients with renal cell cancer with venous thrombus and to investigate impact of various demographical, clinical and histological factors on overall survival (OS). The medical records of 102 adult patients with renal cell cancer with venous thrombus admitted for surgery in Department of General, Vascular and Transplant Surgery from 2012 to 2019 were retrospectively analyzed. The tumor was more frequently located on the right side compared to the left one (55 vs. 47). ⋯ G3-4) (P = .033) were associated with a shorter OS. Patients with renal cell cancer with venous thrombus, with an acceptable perioperative risk, should be treated surgically, because radical nephrectomy with thrombectomy performed in a high volume surgical center is a safe procedure. Neves Zincke 2-4 venous thrombus, higher tumor and nodal staging, as well higher Fuhrman histological grading are associated with a shorter OS.

The gamma-glutamyl transferase to platelet ratio (GPR) has been reported to be as effective as the aspartate transaminase to platelet ratio index (APRI) and fibrosis index based on the 4 factors (FIB-4) in showing the fibrosis stage in patients with chronic hepatitis B. It has been demonstrated that APRI and FIB-4 are successful in the assessment of fibrosis in primary biliary cholangitis (PBC). We investigated the effectiveness of GPR in predicting advanced fibrosis and cirrhosis in patients with biopsy-proven untreated PBC. ⋯ The area under the receiver operating characteristic curve (AUROC) of GPR was 0.84, the cutoff point was 4.81, the sensitivity was 0.41, and the specificity was 0.96 for detecting advanced fibrosis. Our study showed that GPR was more sensitive than APRI and FIB-4 in detecting advanced fibrosis in patients with PBC. GPR could be used as an effective noninvasive marker in PBC to show advanced fibrosis at the time of diagnosis.
