Review Case Reports
Calcineurin Inhibitors Associated Posterior Reversible Encephalopathy Syndrome in Solid Organ Transplantation: Report of 2 Cases and Literature Review.
Posterior reversible encephalopathy syndrome (PRES) is a rare neurologic side effect of calcineurin inhibitors (CNIs) with poorly understood clinical features. We report cases of 2 patients with PRES developing after kidney transplantation and summarize PRES clinical features through a literature review. The 1st case was a 28-year-old man who received a kidney transplant from a deceased donor. ⋯ CNI-associated PRES has a generally favorable prognosis with early diagnosis and prompt treatment including alternating or discontinuing CNIs and blood pressure control. CNI-associated PRES should be considered in patients exhibiting acute neurological symptoms after transplantation. Early diagnosis and immediate treatment are critical for a favorable prognosis.

Multicenter Study Observational Study
Contrast Medium Exposure During Computed Tomography and Risk of Development of End-Stage Renal Disease in Patients With Chronic Kidney Disease: A Nationwide Population-Based, Propensity Score-Matched, Longitudinal Follow-Up Study.
The aim of the study was to investigate the long-term association between contrast medium exposure during computed tomography (CT) and the subsequent development of end-stage renal disease (ESRD) in patients with chronic kidney disease (CKD). We conducted a population-based cohort study using Taiwan's National Health Insurance Research Database. A total of 7100 patients with nonadvanced CKD who underwent contrast medium-enhanced CT were identified and served as the study cohort. ⋯ We further divided the patients who underwent CTs with contrast medium use into ≤1 exposure per year on average, >1 and <2 exposure per year on average, and ≥2 exposure per year on average. After adjusting for confounders, we identified a much higher risk for developing ESRD in the 2 groups of >1 and <2 exposure per year on average and ≥2 exposure per year on average (adjusted HR = 8.13; 95% CI, 5.57-11.87 and adjusted HR = 12.08; 95% CI, 7.39-19.75, respectively) compared with the patients who underwent CTs without contrast medium use. This long-term follow-up study demonstrated that contrast medium exposure was not associated with an increased risk of ESRD development in nonadvanced CKD patients.

Randomized Controlled Trial
The Efficacy of Adjuvant FOLFOX6 for Patients With Gastric Cancer after D2 Lymphadenectomy: A Propensity Score-matched Analysis.
Adjuvant 5-fluorouracil, folinic acid, and oxaliplatin (FOLFOX6) are widely used for treating resected gastric cancer in clinics in China, but only few clinical trials have investigated its efficacy. Using propensity score matching, we evaluated the efficacy of adjuvant FOLFOX6 following D2 lymphadenectomy. Patients who received adjuvant FOLFOX6 following D2 lymphadenectomy (FOLFOX6, n = 113) or D2 lymphadenectomy only (surgery-only, n = 512) between 1998 and 2007 at our center were propensity score-matched; we identified a balanced 1:2 cohort, with 96 patients in the FOLFOX6 group and 192 patients in the surgery-only group. ⋯ Internal validation of the nomogram revealed good predictive abilities, with a bootstrap-corrected concordance index of 0.70. Adjuvant FOLFOX6 following D2 lymphadenectomy is associated with survival benefit in resected gastric cancer. Receiving adjuvant FOLFOX6 can be developed into a nomogram with other independent prognosticators to refine OS prediction and estimation of benefit from adjuvant FOLFOX6 for resected gastric cancer.

An Invert U-Shaped Curve: Relationship Between Fasting Plasma Glucose and Serum Uric Acid Concentration in a Large Health Check-Up Population in China.
There are some published studies focus on the invert U-shaped relationship between fasting plasma glucose (FPG) and serum uric acid (UA), while the threshold value and gender differences of this relationship were still obscure. We aimed to explore the dose-response relation between FPG level and serum UA concentration by conducted this epidemiological research in a large health check-up population in China. A total of 237,703 people were collected from January 2011 to July 2014 in our cross-sectional study; 100,348 subjects age 18 to 89 years and without known diabetes were included for the current analysis. ⋯ Furthermore, the interaction between different FPG level and sex was significant (P < 0.05). An invert U-shape with a threshold of FPG was existed for serum UA level in Chinese adults age 18 to 89 years without known diabetes, and significant gender differences were found. Future researches should pay more attention to this relationship.

Attribution to Heterogeneous Risk Factors for Breast Cancer Subtypes Based on Hormone Receptor and Human Epidermal Growth Factor 2 Receptor Expression in Korea.
We conducted a heterogeneous risk assessment of breast cancer based on the hormone receptor (HR) and human epidermal growth factor receptor 2 (HER2) calculating the risks and population-based attributable fractions (PAFs) for modifiable and nonmodifiable factors. Using matched case-control study design from the Seoul Breast Cancer Study and the national prevalence of exposure, the risks and PAFs for modifiable and nonmodifiable factors were estimated for total breast cancers and subtypes. The attribution to modifiable factors was different for each subtype (luminal A, PAF = 61.4% [95% confidence interval, CI = 54.3%-69.8%]; luminal B, 21.4% [95% CI = 18.6-24.9%]; HER2-overexpression, 59.4% [95% CI = 47.8%-74.3%], and triple negative tumors [TNs], 27.1% [95% CI = 22.9%-32.4%)], and the attribution to the modifiable factors for the luminal A and HER2-overexpression subtypes was higher than that of the luminal B and TN subtypes (P heterogeneity ≤ 0.001). ⋯ Total reproductive factors were also heterogeneously attributed to each breast cancer subtype (luminal A, 65.4%; luminal B, 24.1%; HER2-overexpression, 57.9%, and TN subtypes, -3.1%; P heterogeneity ≤ 0.001). Each pathological subtype of breast cancer by HRs and HER2 status may be associated with heterogeneous risk factors and their attributable risk, suggesting a different etiology. The luminal B and TN subtypes seemed to be less preventable despite intervention for alleged risk factors, even though physical activity had a high preventable potential against breast cancer.
