BACKGROUND/AIMS: Higher level of serum uric acid (SUA) predicts early entry to dialysis in chronic kidney disease (CKD) patients. However, a short-term effect of SUA remains to be elucidated using a novel surrogate endpoint. METHODS: Japanese CKD stage 3 to 4 patients were retrospectively examined (n= 701). The follow-up level of SUA was estimated as time-averaged uric acid (TA-UA). A propensity score for 6.0, 6.5 or 7.0 mg/dL of TA-UA was respectively calculated using baseline 23 covariates...

BACKGROUND: Outcomes of Continuous Flow Left Ventricular Assist Devices (CF-LVADs) as bridge to transplant have significantly improved. The question has arisen whether patients on CF-LVADs have an increased risk of death on the waiting list as to justify a priority allocation (status 1). The aim of this study was to compare the survival following implantation of CF-LVADs to the survival on the waiting list for patients initially listed in United Network for Organ Sharing (UNOS) status 2...

The use of an enabling formulation technique, such as amorphization of a poorly water-soluble crystalline drug, can result in supersaturation with respect to the crystalline form of the drug and thus potentially in a higher degree of absorption after oral administration. The ease with which such drugs can be amorphized is known as their glass forming ability (GFA). In this study, a potential correlation between GFA and supersaturation propensity is investigated. The GFA of 23 different drugs was determined by melt quenching or milling the crystalline drugs to obtain their respective amorphous forms...

BACKGROUND: The rate of cardiovascular implantable electronic device infection (CIEDI) has increased, despite the use of perioperative antibiotics at the time of device placement or revision. This is due, in part, to the presence of multiple comorbid conditions in an elderly population, in general, who require CIED. Statins may have an antibacterial effect, although there is currently no evidence that the likelihood of CIEDI has been impacted by statin use. METHODS: A retrospective cohort study was performed to assess whether statins are associated with a reduced risk of CIEDI...

BACKGROUND: Patients with colorectal peritoneal carcinomatosis have a very poor prognosis. The recently developed consensus molecular subtype (CMS) classification of primary colorectal cancer categorizes tumours into four robust subtypes, which could guide subtype-targeted therapy. CMS4, also known as the mesenchymal subtype, has the greatest propensity to form distant metastases. CMS4 status and histopathological features of colorectal peritoneal carcinomatosis were investigated in this study...

BACKGROUND: Although adjuvant chemotherapy (AC) is widely used after liver resection (LR) for colorectal liver metastasis (CRLM), surgical invasiveness may lead to delay in starting AC, which is preferably started within 8 weeks postoperative. We investigated whether laparoscopic liver resection (LLR) for CRLM facilitates AC start without delay. METHODS: Between November 2014 and December 2016, 117 consecutive CRLM patients underwent LR followed by AC. LLR and OLR were performed in 30 and 87 patients, respectively...

BACKGROUND: There is a well-documented gender difference in offending, with evidence that boys, on average, are more involved in crime than girls. Opinions differ, however, on whether the causes of crime apply to girls and boys similarly. AIMS: Our aim is to explore crime propensity in boys and girls. Our research questions were (1) are there differences between boys and girls in moral values and self-control; (2) are these attributes similarly correlated with offending among girls and boys; and (3) is any interaction effect between morality and self-control identical for girls and boys...

Despite the ubiquity and importance of speeding offenses, there has been little neuroscience research regarding the propensity for speeding among vehicle drivers. In the current study, as a first attempt, we examined the hypothesis that visual inputs during high-speed driving would activate the mesolimbic dopaminergic system that plays an important role in mediating motivational craving. To this end, we used functional magnetic resonance imaging to identify speed-related activation changes in mesolimbic dopaminergic regions during the observation of driver-view videos in two groups that differed in self-reported speeding propensity...

Suicide has become a serious matter in both developed and developing countries. The objective of the present study is to examine the factors affecting suicidal behaviour among adults in Malaysia. A nationally representative data which consists of 10,141 respondents is used for analysis. A trivariate probit model is utilised to identify the probability of having suicide ideation, suicide plan and suicide attempt. Results of the regression analysis show that to ensure unbiased estimates, a trivariate probit model should be used instead of three separate probit models...

BACKGROUND: The relation of dialysis to tumor recurrence in patients with upper tract urothelial cancer (UTUC) is unknown; however, a limited number of small-scale studies suggest that patients with renal diseases prior to UTUC are more likely to exhibit bladder recurrence. We performed a population-based analysis to determine the effect of dialysis on bladder recurrence for patients with UTUC. METHODS: This retrospective cohort study included patients diagnosed with UTUC (2002-2007) from the Taiwan National Cancer Registry and divided them into two groups-dialysis and non-dialysis groups...
