BACKGROUND: The ability to provide accurate prognostic data after hepatectomy for intrahepatic cholangiocarcinoma (ICC) remains poor. We sought to develop and validate a nomogram to predict survival, as well as investigate the clinical implications of underestimating patients' risk of recurrence. METHODS: Patients undergoing curative-intent resection of ICC between 1990 and 2015 at 14 major hepatobiliary centers were included. Variables significant on multivariable analysis were used to construct a nomogram to predict disease-free survival (DFS)...

BACKGROUND: Venous thromboembolism chemoprophylaxis with warfarin is common after total joint arthroplasty. Early response to warfarin initiation has been theorized to engender a transient increase in the risk of venous thromboembolism. We hypothesized that a rapid rise in the international normalized ratio is a risk factor for venous thromboembolism after total joint arthroplasty. METHODS: This study was a retrospective analysis of Medicare patients undergoing elective total joint arthroplasty who were given nomogram-dosed warfarin for venous thromboembolism prophylaxis...

Tumor-associated macrophages (TAMs) are correlated with the prognosis of different types of solid tumors and lymphoma, according to many clinical studies. In vitro experiments have demonstrated the roles of these cells in myeloma cell survival, angiogenesis, immunomodulation, drug resistance, and the interaction between malignant myeloma cells and the microenvironment. Here, we investigated the prognostic significance of TAMs in patients with multiple myeloma (MM). We evaluated the polarized functional status of bone marrow infiltrated by TAMs by immunohistochemical staining of CD68, iNOS, and CD163 in 240 patients with MM from January 2009 to December 2014...

AIMS: To develop a nomogram with severity categories for detrusor overactivity (DO). METHODS: By conducting ice water tests (IWT) in 55 patients with Parkinson's disease, we identified criteria to describe characteristics of the detrusor pressure curves: (1) a gradient of Δpdet over Δt at the maximum detrusor pressure and (2) the area under the curve. In a nomogram, 10 severity categories of DO were established: 1 and 2 were assigned to group A (mild), 3 and 4 to group B (moderate) and 5-10 to group C (severe)...

The outcome of bladder cancer after radical cystectomy is heterogeneous. We aim to evaluate the prognostic value of HALP (hemoglobin, albumin, lymphocyte and platelet) and explore novel prognostic indexes for patients with bladder cancer after radical cystectomy. In this retrospective study, 516 patients with bladder cancer after radical cystectomy were included. The median follow-up was 37 months (2 to 99 mo). Risk factors of decreased overall survival were older age, high TNM stage, high American Society of Anesthesiologists (ASA) grade and low HALP score...

Targeted and untargeted analyses of the sub-5 kDa urine metabolome of genitourinary cancer patients (prostate and/or bladder) were performed without chemical derivatization using capillary electrophoresis-electrospray ionization-mass spectrometry (CE-ESI-MS). For targeted analysis, endogenous levels of sarcosine and 5 other amino acid metabolites implicated in the progression of prostate cancer were quantified in four patients and in a pooled urine sample from healthy volunteers. An untargeted analysis (m/z 50 to 850) of patient urine was performed using the same CE-ESI-MS system identifying over 400 distinct molecular features per patient...

Hypertension is the most common comorbidity among cancer survivors, although there is no model for predicting hypertension in this population. Therefore, we developed a model for predicting hypertension using data from 6,480 Korean cancer survivors who were ≥20 years old. The odds ratios (ORs) for hypertension were calculated using stepwise logistic regression analyses, and a nomogram was generated to predict hypertension. Hypertension was independently associated with an age of ≥65 years (OR: 3.058), male gender (OR: 1...

Continuous intravenous (IV) infusion has been shown to be the best option to administer vancomycin because of its time-dependent bactericidal activity. Available IV vancomycin dosing guidelines in pediatrics with normal renal function leads to less than 50% of patients achieving a vancomycin serum concentration (Css) in the target range (15 to 20 mg/l). The primary objective of this study was to prospectively validate an age-based dosing regimen in pediatric onco-hematology. The secondary objective was to investigate the influence on Css attainment of different variables...
