Abstract
Objective To investigate the relationship between serum uric acid (SUA) levels and ischemic stroke in young patients in the Ganzi Tibetan plateau area. Methods A cross-sectional survey was undertaken from January 2020 to June 2023 involving young patients (age: 15-45 years) diagnosed with ischemic stroke. The survey was conducted at the Department of Internal Medicine of the People's Hospital of Derong County, Ganzi Prefecture. The participants underwent a comprehensive assessment, including questionnaire surveys, physical examinations, laboratory tests, and head computed tomography (CT) examinations. Based on the tertiles of serum uric acid (SUA) levels, the patients were stratified into three groups. Furthermore, stroke severity was classified into mild (1-4 points), moderate (5-15 points), and severe (>15 points) categories using the National Institute of Health Stroke Scale. Results The severe stroke group exhibited higher levels of age, glucose, systolic blood pressure, serum triglyceride, low-density lipoprotein cholesterol, and serum uric acid (SUA) compared to the mild stroke group (P < 0.05). Furthermore, the likelihood of male sex, advanced age, smoking, and a family history of stroke, diabetes mellitus, and heart disease were significantly elevated in the severe stroke group compared to the moderate stroke group (P < 0.05). Multivariate logistic regression analysis conducted on young adults residing in highland areas revealed a significant association between SUA levels and the risk of stroke. Conclusion Elevated SUA levels serve as a distinct risk factor for the development of a major stroke in young patients in highland areas. At SUA levels of 320.56 mol/L, the risk of a moderate-to-severe stroke is noticeably elevated.

Abstract
Objectives: Single umbilical artery (SUA) is considered the most common abnormality of the umbilical artery. The objective of the study was to evaluate the perinatal prognosis of fetuses with SUA and to describe the associated malformations. The significance of the study is represented by examining whether our findings are in correlation with data already described.Methods: We performed a prospective cohort study on singleton pregnancies complicated with SUA. The study population was composed of women with singleton pregnancies who were examined at the Department of Obstetrics and Gynecology of the Târgu Mures County Emergency Clinical Hospital between 2012 and 2021.Results: The incidence of SUA in the study population was 0.48%. C-section was performed in 40 cases with SUA and in 5258 cases with no SUA (RR:1.56, P<0.05.) From the total number of 2249 premature deliveries, 23 newborns were diagnosed with SUA (RR:2.12, P<0.05.) From the total number of 869 deliveries with low birth weight (LBW) newborns, 13 were associated with SUA (RR: 3.12, P<0.05.) There were 206 pregnancies noted with antenatal fetal demise after 24 weeks of gestation, and only 2 of them were with SUA (RR:2.01, P>0.05.) Fetal and neonatal malformations were described in 290 cases, and 28 were associated with SUA (R:21.96, P<0.05.) In 57 of 85 cases (67.05%), we found iSUA, and 28 newborns (32.95%) had minor, major, or other associated pathologies. We found two cases of trisomy 18 and one case with trisomy 13 associated with SUA. Investigating the malformations associated with SUA, the most common were cardiac and great vessels malformations (12), followed by limb malformations (8), urogenital malformations (7), digestive tract malformations (7), central nervous system malformations (4), and in one case we found cleft palate.Conclusions: Perinatal prognosis regarding SUA is significantly poorer than in cases without this pathology. One-third of fetuses with SUA were associated with fetal anomalies. The most common pathologies associated with SUA were cardiovascular, limb, urogenital, and digestive system malformations. Our data are similar to those described in other studies; therefore, we conclude, we can implement the general recommendations in our region regarding counselling patients.

Abstract
BACKGROUND N,N-diethyl-m-toluamide (DEET) is a widely used active ingredient in insect repellents, and its effects on human health have been a matter of debate. This study aims to investigate the relationship between DEET exposure and hyperuricemia in the adult population. METHODS Our study utilized a cross-sectional design and analyzed data from adult participants of the National Health and Nutrition Examination Survey (NHANES) conducted between 2007 and 2016. 3-diethyl-carbamoyl benzoic acid (DCBA) was used as a specific indicator of DEET exposure. DCBA was categorized using quartiles based on its distribution within the study population. Multiple linear regression models were employed to examine the association between DCBA exposure and serum uric acid (SUA) levels in adults. The relationship between DCBA and the prevalence of hyperuricemia in adults was assessed using multiple logistic regression models. Dose-response relationships were analyzed using restricted cubic spline regression. RESULTS A total of 8708 participants were included in the study. The mean age of the participants was 46.49 years, and the total number of male participants was 50.93%. The median levels of DCBA and SUA were 2.07 ng/mL and 5.40 mg/dL, respectively. Hyperuricemia was found in 19.99% of the participants. In multivariate-adjusted linear regression models, it was found that higher SUA levels were associated with the highest quartile of DCBA compared with the lowest quartile of DCBA (β [95% CI]: 0.19 [0.08, 0.30], Ptrend<0.001). After adjusting for confounders, a positive association was found between the prevalence of hyperuricemia and DCBA levels (OR [95% CI] quartile 4 vs. 1: 1.41 [1.14-1.74], Ptrend<0.001). Furthermore, linear associations were observed between DCBA concentrations and SUA levels (P for nonlinearity = 0.479) and the prevalence of hyperuricemia (P for nonlinearity = 0.755). CONCLUSION Higher DCBA concentrations were found to have a positive association with the prevalence of hyperuricemia in the general adult population.

Abstract
BACKGROUND AND AIMS Chronic kidney disease (CKD) is a public health concern worldwide and has been recognized as a significant risk factor for cardiovascular disease. The elevated level of uric acid (hyperuricemia) has been suggested to be associated with obesity, hypertension, cardiovascular disease and diabetes. However, there is limited information on the relationship between hyperuricemia and CKD. Therefore, this study aimed to estimate the prevalence of CKD and assess its relationship with hyperuricemia in Bangladeshi adults. METHODS In this study, blood samples were collected from 545 participants (398 males and 147 females) aged ≥ 18 years. Biochemical parameters such as serum uric acid (SUA), lipid profile markers, glucose, creatinine and urea were measured by colorimetric methods. The estimated glomerular filtration rate (eGFR) and CKD were determined based on serum creatinine levels with existed formula. Multivariate logistic regression analysis was performed to evaluate the association between SUA and CKD. RESULTS The overall prevalence of CKD was 5.9% with 6.1% in males and 5.2% in females. Hyperuricemia was prevalent in 18.7% of participants with 23.2% in males and 14.6% in females. An increasing trend of CKD prevalence was observed with increasing age in the groups. The mean eGFR level was significantly lower in male (95.1 ± 31.8 ml/min/1.73m2) than in female (109.3 ± 77.4 ml/min/1.73m2) subjects (p < 0.01). The mean level of SUA was significantly higher (p < 0.01) in participants having CKD (7.1 ± 1.9 mg/dL) than in participants without CKD (5.7 ± 1.6 mg/dL). A decreasing trend for eGFR concentration and an increasing trend for CKD prevalence was observed across the SUA quartiles (p < 0.001). In regression analysis, a significant positive association was found between hyperuricemia and CKD. CONCLUSION This study showed an independent association between hyperuricemia and CKD in Bangladeshi adults. Further mechanistic studies are needed to explore the potential link between hyperuricemia and CKD.

Abstract
Background-There are conflicting data in the international literature on the risks of abnormal fetal growth in fetuses presenting an isolated single umbilical artery (SUA), and the pathophysiology of this complication is poorly understood. Objective-To evaluate if changes in diameter of the remaining umbilical artery in fetuses presenting an isolated SUA are associated with different fetal growth patterns. Study design-This was a two-center prospective longitudinal observational study including 164 fetuses diagnosed with a SUA at the 20-22-week detailed ultrasound examination and 200 control fetuses with a three-vessel cord. In all cases, the diameters of the cord vessels were measured in a transverse view of the central portion of the umbilical cord, and the number of cord vessels was confirmed at delivery. Logistic regression and nonparametric receiver operating characteristic (ROC) analysis were carried out to evaluate the association of the umbilical artery diameter in a single artery with small for-gestational age (SGA) and with fetal growth restriction (FGR). The impact of artery dimension was adjusted for maternal BMI, parity, ethnicity, side of the remaining umbilical artery and umbilical resistance index (RI) in the regression model. Results-A significantly (p < 0.001) larger mean diameter was found for the remaining artery in fetuses with SUA compared with controls (3.0 ± 0.9 vs. 2.5 ± 0.6 mm). After controlling for BMI and parity, we found no difference in umbilical resistance and side of the remaining umbilical artery between the SUA and control groups. A remaining umbilical artery diameter of >3.1 mm was found to be associated with a lower risk of FGR, but this association failed to be statistical significant (OR = 0.60, 95% CI = 0.33-1.09, p value = 0.089). We also found that the mean vein-to-artery area ratio was significantly (p < 0.001) increased in the SUA group as compared with the controls (2.4 ± 1.8 vs. 1.8 ± 0.9; mean difference = 0.6; Cohen's d = 0.46). Conclusion-In most fetuses with isolate SUA, the remaining artery diameter at 20-22 weeks is significantly larger than in controls. When there are no changes in the diameter and, in particular, if it remains <3.1 mm, the risk of abnormal fetal growth is higher, and measurements of the diameter of the remaining artery could be used to identify fetuses at risk of FGR later in pregnancy.

Abstract
OBJECTIVES Weight reduction may reduce serum uric acid (SUA). This study aimed to examine the changes of SUA before and after bariatric surgery in patients with obesity with or without hyperuricaemia and gout. METHODS This is a retrospective analysis of 147 routinely collected data on hospital patients with obesity who underwent bariatric surgery. The body weight and SUA were measured at baseline and after surgery at 1-7 days, 1, 3, 6 and 12 months. RESULTS The mean (95% CI) weight reduction of 147 patients was 30.7 (28.7, 32.7) kg 1 year after surgery (P < 0.001). SUA decreased rapidly from 419.0 (400.1, 437.8) µmol/l at baseline to 308.4 (289.6, 327.2) µmol/l at 1-7 days, flared up to 444.8 (423.9, 465.6) µmol/l at 1 month, then decreased again to 383.8 (361.5, 406.1) µmol/l at 3 months, 348.9 (326.3, 371.5) µmol/l at 6 months and 327.9 (305.3, 350.5) µmol/l at 12 months (P < 0.001). Similar trends but more rapid reductions were observed in 55 hyperuricaemia patients and 25 gout patients. All 25 gout patients had an elevated SUA above the therapeutic target (≥360µmmol/l) at baseline, but in 10 patients it was reduced below this target at 12 months. The mean reduction (95% CI) of SUA in all patients and gout patients was 84.3 (63.1-105.4) and 163.6 (103.9, 223.3) µmmol/l, respectively. CONCLUSION Bariatric surgery significantly reduces body weight and SUA for obese patients with hyperuricaemia and gout. Gout may be considered as an indicator for this surgical treatment in people with severe obesity.

Abstract
BACKGROUND The association between residential greenness and hyperuricemia remains unclear, especially in developing countries. The current study aimed to explore the associations between residential greenness and both serum uric acid (SUA) levels and hyperuricemia in a Chinese rural population and to examine potential pathways of these associations. METHODS In this cross-sectional study, 38,721 rural residents were recruited from the baseline survey of the Henan Rural Cohort study in 2015-2017. Two satellite-derived vegetation indices, i.e., the normalized difference vegetation index (NDVI) and the enhanced vegetation index (EVI), were used to estimate residential greenness. Air pollution was determined by two proxies: particulate matter with aerodynamic diameter ≤ 2.5 μm (PM2.5) and nitrogen dioxide (NO2). Hyperuricemia was defined as SUA levels of >417 μmol/L and > 357 μmol/L for men and women, respectively. Multivariable-adjusted linear regression and logistic regression models were applied to investigate the associations of greenness with SUA and hyperuricemia, and mediation analyses were used to explore possible mechanisms underlying the associations. RESULTS An interquartile range (IQR) increase in both EVI and NDVI in the 500 m buffer was significantly associated with reductions in SUA levels of -7.23 μmol/L (95% confidence interval (CI): -8.96, -5.50) and -4.38 μmol/L (95% CI: -5.93, -2.83), respectively. The same increases in EVI500-m and NDVI500-m were associated with 13.8% (95% CI: 5.8%, 21.2%) and 13.0% (95% CI: 5.6%, 19.8%) lower hyperuricemia prevalence, respectively. These associations were stronger in older people (age ≥ 65), men or participants with higher averaged monthly income. The associations were partly mediated by physical activity and BMI, while no mediation effect was observed for air pollution. CONCLUSIONS Higher levels of residential greenness were significantly associated with lower SUA levels and hyperuricemia prevalence in the Chinese rural population. BMI and physical activity may play important mediating roles in the associations.

Abstract
Background and aims The association between serum uric acid (SUA) and tea consumption has been studied in previous work, and there were arguments among various population group employed as well as different statistical approaches. The aim of this work is to investigate the tea effect on SUA levels among older adults by comparing three large-scale populations with both cross-sectional and longitudinal analyses. Method We examined the relationship between intake and SUA levels among older adults using linear regression. All the studies include the parameters SUA levels, tea intake, age, sex, education level, smoking status, alcohol drinking status, body mass index (BMI), and health history (diabetes, hypertension, and fasting plasma glucose). The cross-sectional analyses were conducted with 4579 older adults in the Weitang Geriatric Diseases Study (WGDS, ≥60 years), 2440 in the China Health and Nutrition Survey (CHNS, ≥60 years) and 1236 in the Chinese Longitudinal Healthy Longevity Survey (CLHLS, ≥62 years); and the longitudinal analyses were performed with 3870 (84.5%) in the WGDS and 420 (34.0%) in the CLHLS. Multivariable linear regression analyses were performed in both cross-sectional and longitudinal studies. Results Cross-sectional studies showed that tea consumers tended to have higher SUA levels than non-tea consumers in all the three datasets (P < 0.05). However, longitudinal associations of SUA levels with tea consumption had no statistical significance (P>0.05). The results of sex-stratified analyses were consistent with those of the whole datasets. Conclusions This work implied that any possible association between tea consumption and SUA levels could be very weak.

Abstract
OBJECTIVE To analyze the morbidity of the practice of daily self-dilatation (SD) in patients undergoing total prostatectomy, who have had artificial urinary sphincter (AUS) for urinary incontinence (UI) and who have had a recurrence of endoscopically treated vesicourethral anastomosis (VUS) stenosis. MATERIALS AND METHOD One hundred and thirty-eight patients with SUA for urinary incontinence (UI) fitted between 1998 and 2007 were divided into two groups. Thirty-five patients have had used self-dilatation (SD) for recurrent anastomotic stenosis (SD group) and 103 patients did not perform SD (non-SD group). These two groups were compared for explantation rate (erosion-infection), revision rate (urethral atrophy and mechanical failure) and 2-year functional results. The uni- and multivariate statistical analysis taken into consideration confounding factors such as age and radiotherapy history. The functional assessment was done by the validated IQoL, Ditrovie and MHU tests. RESULTS Patients in both groups were comparable except for the importance of urinary incontinence assessed by PAD test and questionnaires. The explantation rate was significantly higher in the "SD" group (28.5% vs 7.77%) and (OR=4.68, 95% CI [1.490-15.257], P=0.006). There was no significant difference between the two groups in the surgical revision rate (32% vs 20%, OR=0.44, P=0.09). The functional results at two years did not show any significant difference. CONCLUSIONS The use of self-dilation for recurrence of stenosis of vesicourethral anastomosis after prostatectomy exposes patients fitted with an SUA to a higher explantation rate. LEVEL OF EVIDENCE 3.

Abstract
OBJECTIVES Single umbilical artery (SUA) is associated with congenital malformations in most organ systems, but reported findings have not been consistent. While it has been suggested that genetic and persisting environmental factors influence the development of SUA, it is not known whether there is an increased risk of recurrence in a subsequent pregnancy of the same woman. The aims of this study were to investigate the occurrence of, and risk factors for, SUA in Norway, to assess its association with congenital malformations and trisomies 13, 18 and 21 and to study the risk of recurrence of SUA in subsequent pregnancies. METHODS This was a population-based study of all (n = 918 933) singleton pregnancies of > 16 weeks' gestation recorded in the Medical Birth Registry of Norway from 1999 to 2014. To identify risk factors and congenital malformations associated with SUA, generalized estimating equations and logistic regression were used to calculate odds ratios (OR) with 95% CIs. ORs were also calculated for the recurrence of SUA in subsequent pregnancy. RESULTS The occurrence of SUA in our population was 0.46% (4241/918 933). Parity ≥ 4, smoking, maternal pregestational diabetes, epilepsy, chronic hypertension, previous Cesarean delivery and conception by assisted reproductive technology increased the odds of having SUA. There was a particularly strong association between SUA and gastrointestinal atresia or stenosis in the neonate, with ORs of 25.8 (95% CI, 17.0-39.1) and 20.3 (95% CI, 13.4-30.9) for esophageal and anorectal atresia or stenosis, respectively, followed by an OR of 5.9 (95% CI, 1.9-18.5) for renal agenesis. SUA was associated with an up to 7-8 times increased risk of congenital heart defects. There was an association with microcephaly, congenital hydrocephalus and other congenital malformations of the brain and spinal cord. Diaphragmatic hernia, limb reductions and cleft lip or palate had a weaker association with SUA, with ORs ranging from 4.8 to 2.8. The associations with trisomy 18 and 13 were equally strong (OR 14.4 (95% CI, 9.3-22.4) and OR 13.6 (95% CI, 6.7-27.8), respectively), and the risk of trisomy 21 was doubled (OR 2.1 (95% CI, 1.2-3.6)). Pregnancies with SUA, with or without an associated malformation, had a 2-fold increased risk for SUA in a subsequent pregnancy. CONCLUSIONS SUA is associated strongly with gastrointestinal atresia or stenosis, suggesting common developmental mechanisms. The increased risk of recurrence of SUA suggests that genetic and/or persisting environmental factors influence the risk. We found that SUA had equally strong associations with trisomies 13 and 18. © 2019 The Authors.

Abstract
Objective: To describe the prevalence of metabolic syndrome (MetS) in adolescents and its association with several MetS-related biochemical markers. Methods: A cross-sectional analysis was carried out and data were extracted from the Nutrition and Health Surveillance in Primary and Secondary school students of Beijing (NHSPSB) 2017. Participants were aged 10-15 years old. MetS was diagnosed using the recommended criteria for Chinese adolescents. The associations among MetS, biochemical biomarkers, and socioeconomic status were estimated by multivariable linear regression. Results: The prevalence of MetS in adolescents in Beijing was 3% in the total sample, 4% in boys, and 2% in girls. Moreover, the prevalence of MetS in the overweight and obesity populations were 5% and 12% respectively. The prevalence of MetS remained higher in boys than in girls. The concentrations of alanine aminotransferase (ALT), serum uric acid (SUA), low density lipoprotein (LDL), and C-reactive protein (CRP) were higher in the MetS children in comparison with non-MetS children (All p < 0.05), while the high-density lipoprotein (HDL) concentration was lower in MetS children. After adjusting for socioeconomic parameters in the multivariable regression model, MetS was strongly associated with ALT, SUA, HDL, and LDL. The five components of MetS indicated that abdominal obesity and a high serum triglyceride (TG) concentration were tightly linked with ALT, SUA, LDL, and CRP; while a low HDL concentration and elevated blood pressure were related to enhanced ALT, UA, and CRP. Additionally, impaired fasting glucose was only related to increased ALT. Conclusion: The epidemiological issues of MetS in Beijing adolescents should be known across socioeconomic classes. Early intervention strategies, such as dietary pattern interventions and physical excise, should be designed for that population to reduce the disease burdens of cardiovascular disease (CVD), Type 2 diabetes (T2D), and steatohepatitis in adulthood.

Abstract
Recent years, we has witnessed a sharp increase in the complications of Type 2 diabetes mellitus (T2DM) with nonalcoholic fatty liver disease (NAFLD). Here we aimed to determine the risk factors for T2DM patients with NAFLD and the relationship of serum uric acid (SUA) in these complications. We performed retrospective analysis of 300 T2DM patients admitted into our hospital from April 2010 to January 2014. We divided the T2DM patients into two groups based on whether the patients also had NAFLD or not, Group A (without NAFLD, 155 cases) and Group B (with NAFLD, 145 cases). General information of the patients was collected and analyzed statistically. Meanwhile, we detected and compared the blood biochemistry, glucose, and fasting insulin (FINS), and further performed Logistic regression analysis and determined the risk factors in T2DM patients with NAFLD. Significantly higher BMI, waist circumference, hip circumference, WHR, systolic, and diastolic blood pressure were observed in T2DM patients with NAFLD than the patients without NAFLD, which were statistically different (P < 0.05). There were also significant higher levels of TC, TG, ALT, AST, GGT, and SUA in T2DM patients with NAFLD than those in patients without NAFLD, which were statistically different (P < 0.05). Significantly higher levels of FPG, FINS, and HOMA-IR were observed in the T2DM patients with NAFLD than those without, which were statistically significant (P < 0.05). Logistic regression analysis also showed high BMI, WHR, TG, and SUA were independent risk factors in T2DM patients with NAFLD (P < 0.05). Meanwhile, SUA levels were positively correlated with BMI, W, H, WHR, hip circumference, waist circumference, TG, ALT, AST, GGT, FPG, FINS, and HOMA-IR, which were statistically significant (P < 0.05). The risk factors for T2DM patients with NAFLD are mainly BMI, WHR, TG, and SUA. Our findings provide clinical implications for the prevention and early diagnosis of T2DM patients with NAFLD.

Abstract
BACKGROUND The serum uric acid (SUA) is the end-product from the metabolic breakdown of purine nucleotides. It has been considered to be a prognostic factor for malignant tumor in several researches. However, its prognostic value in patients with esophageal squamous cell carcinoma (ESCC) has not been elucidated. METHODS We retrospectively reviewed the records of 209 ESCC patients who underwent R0 esophagectomy. A receiver operating characteristic (ROC) curve analysis was used to determine the optimal cut-off value for pre-operative SUA levels and to divide the ESCC patients into two groups. Furthermore, we analyzed the pre-operative serum uric acid (SUA) levels and its relationship with the clinicopathological parameters and the prognosis of 209 ESCC patients. RESULTS Optimal cut-off value for pre-operative SUA in ROC analysis was 304.5 μ mol/l (sensitivity 67.46%, specificity 65.06%). SUA low- or high-levels were associated with gender (P< 0.001), smoking status (P< 0.001), pN statues (P= 0.003) and TNM stage (P= 0.010). SUA levels, tumor differentiation and pTNM stage were independent predictors of ESCC patient survival in a multivariate analysis. CONCLUSIONS The pre-operative level of SUA is an independent prognostic predictor in ESCC patients who undergo R0 esophagectomy and patients with higher SUA level may have an unfavorable survival probability.

Abstract
Nonalcoholic fatty liver disease (NAFLD), tightly linked to the metabolic syndrome (MS), has emerged as a leading cause of chronic liver disease worldwide. Since it is potentially progressive towards non-alcoholic steatohepatitis (NASH) and hepatic fibrosis, up to cirrhosis and its associated complications, the need for predictive factors of NAFLD and of its advanced forms is mandatory. Despite the current "gold standard" for the assessment of liver damage in NAFLD being liver biopsy, in recent years, several non-invasive tools have been designed as alternatives to histology, of which fibroscan seems the most promising. Among the different serum markers considered, serum uric acid (SUA) and ferritin have emerged as possible predictors of severity of liver damage in NAFLD. In fact, as widely described in this review, they share common pathogenetic pathways and are both associated with hepatic steatosis and MS, thus suggesting a likely synergistic action. Nevertheless, the power of these serum markers seems to be too low if considered alone, suggesting that they should be included in a wider perspective together with other metabolic and biochemical parameters in order to predict liver damage.

Abstract
OBJECTIVE To determine whether an isolated single umbilical artery (iSUA) is an independent risk factor for perinatal mortality in term neonates with normal estimated fetal weight (EFW) prior to delivery. METHOD A population-based study was conducted, including all deliveries occurring between 1993 and 2013, in a tertiary medical center. Pregnancies with and without iSUA were compared. Multiple gestations, chromosomal, and structural abnormalities were excluded from the cohort. Only pregnancies delivered at term with normal EFW evaluated prior to delivery were included. Stratified analysis was performed using multiple logistic regression models to evaluate the risk of adverse outcomes and perinatal mortality for iSUA fetuses. RESULTS During the study period, 233,123 deliveries occurred at "Soroka" University Medical Center, out of which 786 (0.3 %) were diagnosed with iSUA. Different pregnancy complications were more common with iSUA fetuses including: placental abruption (OR = 3.4), true knot of cord (OR = 3.5) and cord prolapse (OR = 2.8). Induction of labor and cesarean delivery were also more common in these pregnancies (OR = 1.5 and OR = 1.9, respectively). iSUA neonates had lower Apgar scores at 1 and 5 min (OR = 1.8, OR = 1.9, respectively) compared to the control group and perinatal mortality rates were higher both antenatally (IUFD, OR = 8.1) and postnatally (PPD, OR = 6.1). CONCLUSION iSUA appears to be an independent predictor of adverse perinatal outcomes in term neonates.

Abstract
Elevated serum uric acid (SUA) or urate is associated with inflammation and gout. Recent evidence has linked urate to cancers, but little is known about urate effects in prostate cancer. Activins are inflammatory cytokines and negative growth regulators in the prostate. A hallmark of prostate cancer progression is activin insensitivity; however, mechanisms underlying this are unclear. We propose that elevated SUA is associated with prostate cancer counteracting the growth inhibitory effects of activins. The expression of activins A and B, urate transporter GLUT9 and tissue urate levels were examined in human prostate disease. Intracellular and secreted urate and GLUT9 expression were assessed in human prostate cancer cell lines. Furthermore, the effects of urate and probenecid, a known urate transport inhibitor, were determined in combination with activin A. Activin A expression was increased in low-grade prostate cancer, whereas activin B expression was reduced in high-grade prostate cancer. Intracellular urate levels decreased in all prostate pathologies, while GLUT9 expression decreased in benign prostatic hyperplasia, prostatitis and high-grade prostate cancer. Activin responsive LNCaP cells had higher intracellular and lower secreted urate levels than activin-insensitive PC3 cells. GLUT9 expression in prostate cancer cells was progressively lower than in prostate epithelial cells. Elevated extracellular urate was growth promoting in vitro, which was abolished by the gout medication probenecid, and it antagonized the growth inhibitory effects of activins. This study shows for the first time that a change in plasma or intracellular urate levels, possibly involving GLUT9 and a urate efflux transporter, has an impact on prostate cancer cell growth, and that lowering SUA levels in prostate cancer is likely to be therapeutically beneficial.

Abstract
Plant immune receptors belonging to the receptor-like kinase (RLK) family play important roles in the recognition of microbial pathogens and activation of downstream defense responses. The Arabidopsis mutant snc4-1D contains a gain-of-function mutation in the RLK SNC4 (SUPPRESSOR OF NPR1-1, CONSTITUTIVE4), which leads to constitutive activation of defense responses. Analysis of suppressor mutants of snc4-1D identified two conserved splicing factors, SUA (SUPPRESSOR OF ABI3-5) and RSN2 (REQUIRED FOR SNC4-1D 2), that are required for the constitutive defense responses in snc4-1D. In sua and rsn2 mutants, SNC4 splicing is altered and the amount of SNC4 transcripts is reduced. Further analysis showed that SUA and RSN2 are also required for the proper splicing of CERK1 (CHITIN ELICITOR RECEPTOR KINASE1), which encodes another RLK that functions as a receptor for chitin. In sua and rsn2 mutants, induction of reactive oxygen species by chitin is reduced and the non-pathogenic bacteria Pseudomonas syringae pv. tomato DC3000hrcC grows to higher titers than in wild-type plants. Our study suggests that pre-mRNA splicing plays important roles in the regulation of plant immunity mediated by the RLKs SNC4 and CERK1.

Abstract
BACKGROUND Few studies have examined the association between elevated serum uric acid (SUA) levels and psoriasis, and their results have been inconclusive because most of these studies did not take into account the confounding effects of coexisting features of the metabolic syndrome. OBJECTIVE We compared the prevalence of hyperuricemia and SUA levels between psoriatic patients and control individuals. METHODS Levels of SUA were measured in 119 consecutive psoriatic patients and 119 control individuals matched for age, sex, and body mass index. RESULTS Compared with control subjects, psoriatic patients had higher SUA levels (5.61 ± 1.6 vs 4.87 ± 1.4 mg/dL; P < .001) and a remarkably greater prevalence of asymptomatic hyperuricemia (19% vs 7%; P < .001). Multivariate logistic regression analysis revealed that psoriasis was the strongest predictor of hyperuricemia (odds ratio 3.20; 95% confidence interval 1.32-7.58; P < .01) after adjusting for age, sex, and metabolic syndrome features. LIMITATIONS The cross-sectional design of this study does not allow us to draw any conclusion about a causal relation between psoriasis and hyperuricemia. CONCLUSIONS Hyperuricemia is a common finding in psoriatic patients. Its treatment might be clinically useful for the global treatment of patients.

Abstract
OBJECTIVE The aim of this study was to investigate the metabolic risk factors for fatty liver disease in the elderly, and determine the prevalence of fatty liver disease in the elderly in Wuhan, central China. METHODS The study was a case-control study based on all 4226 adults above 60 years of age from a cohort investigated in 2010-11 at the medical examination center of Zhongnan hospital, using 3145 randomly selected adults under 60 years of age from the same cohort as controls. Fatty liver disease (FLD) was identified with ultrasound imaging. The risk factors measured were body mass index (BMI), and plasma concentrations of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL), low density lipoprotein (LDL) and serum uric acid (SUA). The probability of steatohepatitis with advanced fibrosis was predicted using a score based on BMI, age, ALT, and TG (BAAT),and using AST/ALT ratio (AAR). RESULTS FLD was higher in the elderly (26.7%) than in the non-elderly (22.8%) and similar in the elderly between men and women (26.6% vs 27.0%, p>0.05). BMI, TC, TG, LDL, SUA, AST and ALT were all significantly higher in FLD, whereas the level of HDL was markedly lower. Multiple regression analyses showed that obesity, high TC, TG, SUA, low HDL, and elevated ALT, AAR<1 were closely related to the elderly FLD, while male sex, obesity, high TC, TG, low HDL, elevated ALT, AST and AAR<1 were closely related to the non-elderly FLD. The prevalence of steatohepatitis with advanced fibrosis estimated as BAAT index≥3 was 2.4% in all subjects, and was higher in the elderly FLD patients than in the non-elderly FLD patients. CONCLUSION The prevalence of FLD is higher in the elderly, and is broadly related to the same metabolic risk factors as in the non-elderly. However, female-sex is no longer protective with increasing age, and the prevalence of steatohepatitis with advanced fibrosis is estimated to be considerably higher in the elderly FLD patients than in the non-elderly FLD controls.
