Abstract
BACKGROUND Hemoglobin (Hb) measurement is a conventional test during perinatal visits. Hb concentration is related to iron supplement. However, studies focusing on Hb levels, iron supplement, and pregnancy outcomes are scarce. This study aimed to determine whether Hb levels and iron supplement were associated with the risk of gestational diabetes mellitus (GDM). METHODS A running hospital-based cohort was conducted from August, 2011. The demographic data and medical information were collected individually through questionnaires and patient medical records. Multiple linear regression was applied for the association between Hb levels, iron supplement, and blood glucose. Multiple logistic regression was used for evaluating odds ratios between Hb levels, iron supplement, and GDM. RESULTS Hb levels during first (T1) and second trimester (T2) of pregnancy were significantly and positively associated with blood glucose and GDM risk. After adjusting for age, prepregnancy body mass index, and other risk factors, pregnant women with Hb ≥ 11 g/dL and iron supplement had higher postprandial blood glucose at 1 hour (Hb ≥ 11 g/dL in T2 and iron supplement in T1: β = 0.860,P = <0.001; Hb ≥ 11 g/dL in T2 and iron supplement in T2: β = 0.960,P < 0.001; Hb ≥ 11 g/dL in T1 and iron supplement in T2: β = 1.133, P = 0.033) and GDM risks (odds ratio [OR] = 1.53, 95% confidence interval [CI]: 1.05-2.24; OR = 1.92, 95% CI: 1.13-3.35; OR = 2.15, 95% CI: 1.07-4.34, respectively), compared with those with Hb < 11 g/dL and without iron supplement. CONCLUSION High Hb concentration and iron supplements without anemia increased postprandial blood glucose and risks for GDM. It indicates that pregnant women with good Hb levels should not be advised to take iron supplements during pregnancy.

Abstract
OBJECTIVE To identify the effect of preoperative anemia on the prognosis of patients with upper tract urothelial carcinoma (UTUC) following radical nephroureterectomy. METHODS Clinicopathological and prognosis data on 686 patients with UTUC who underwent RNU at Peking University First Hospital between January 2000 and December 2013 were retrospectively analyzed. Preoperative anemia was defined as hemoglobin <130 g/L in men and <120 g/L in women based on the World Health Organization classification. The Kaplan-Meier method with log-rank test was applied to estimate the effect of anemia on survival. The associations of clinicopathologic features with overall survival and cancer-specific survival were evaluated using univariate and multivariate Cox regression models. RESULTS There were 303(44.2%, 303/686) male and 383(55.8%, 383/686) female patients, and the median age was 68 years (interquartile range: 60-74 years). In all, 320 (46.6%, 320/686) patients were anemic before surgery. The median follow-up duration was 47 months. In all, 160 (23.3%) patients died, 141 (20.6%) died of cancer and 19 (2.7%) died of other disease or accidents. Preoperative anemia was associated with gender (P=0.002), age (P<0.001), lymph node positive (P=0.026), increased tumor grade (P=0.018), concomitant carcinoma in situ (P=0.038), tumor necrosis (P=0.007) and poor renal function (P<0.001). In univariate analysis, overall mortality was correlated with pre-operative anemia (P<0.001), gender (P=0.009), hydronephrosis (P=0.024), tumor stage (P<0.001), lymph node positive (P<0.001), tumor grade (P<0.001), tumor architecture(P<0.001), sarcomatoid differentiation (P=0.013), history of ureteroscope (P=0.033) and tumor hemorrhage (P<0.001); cancer-specific mortality was correlated with preoperative anemia (P=0.001), gender (P=0.001), hydronephrosis (P=0.043), tumor stage (P<0.001), lymph node positive (P<0.001), tumor grade (P<0.001), tumor architecture (P<0.001), sarcomatoid differentiation (P=0.016), history of ureteroscope (P=0.028) and tumor hemorrhage (P=0.003). A multivariate Cox proportional hazards model indicated that preoperative anemia was an independent prognositic predictor for overall mortality (P<0.001, HR=1.861) and cancer-specific mortality (P=0.003, HR=1.688). CONCLUSION The preoperative anemia is an independent risk factor for cancer-specific survival and overall survival. Hemoglobin levels should be considered during patient counseling and in decision-making for further therapy.
