Integrated prognostication associated with intrahepatic cholangiocarcinoma by contrast-enhanced computed tomography: the adjunct generate associated with radiomics.
  © 2020 Wiley Periodicals, Inc.BACKGROUND Maternal folate status and obesity are known risk factors for neural tube defects (NTD) in the offspring. We examined the association between body mass index (BMI) categories and blood folate concentrations, specifically, red blood cell (RBC) folate concentrations indicative of NTD risk among nonpregnant women of child-bearing age (20-44 years) in the United States. METHODS We used data from 2007 to 2010 US National Health and Nutrition Examination Survey (NHANES). Overweight, obesity, and strata within obesity were examined. Serum and RBC folate concentrations were examined as continuous and categorical variables. RBC folate concentrations were grouped indicating high (≤585 nmol/L) and elevated risk (586-747 nmol/L) for NTDs. Unadjusted and adjusted prevalence odds ratios (aPOR) and their 95% confidence intervals (CI) were estimated using logistic regression. RESULTS Of the 30,878 participants, 25.6% were overweight, 32.7% obese, and 32.3% had RBC folate concentration indicating NTD risk ( less then 748 nmol/L). Overweight was not associated with RBC folate level for NTD risk; however, a marginally significant negative association was noted for overall obesity and RBC folate concentrations indicative of elevated NTD risk (aPOR = 0.76; 95% CI = 0.45, 1.00).  https://www.selleckchem.com/pharmacological_epigenetics.html  A significant protective association was noted between Class 3 obesity (BMI ≥40 kg/m2 ) and folate concentration indicative of high NTD risk (≤585 nmol/L; aPOR = 0.46; 95% CI = 0.24, 0.89). CONCLUSIONS The prevalence of RBC folate concentrations indicating elevated or high NTD risk varied by level of obesity among nonpregnant women of child-bearing age. Further studies are needed to understand the folate pathway in overweight and obese women and subsequent NTD risk in their offspring. © 2020 Wiley Periodicals, Inc.A method for determining amitraz and 2,4-dimethylaniline in honey was established by using ultra-high-performance liquid chromatoghaphy and Q Exactive after applying quick, easy, cheap, effective, rugged, and safe extracting process. A suitable extraction method was designed to extract the amitraz and 2,4-dimethylaniline after a suitable amount of honey samples was dissolved. A Thermo Syncronis C18 column (100 × 2.1 mm, 1.7 μm) was used for chromatographic separation of the samples. Then the two compounds were quantitatively analyzed via a program of Q Exactive. The linearity of amitraz and 2,4-dimethylaniline was good in the concentration range of 0.5-100 μg/L, and the correlation coefficient R2 was >0.99. The average recovery and relative standard deviation of each component were 81.3-90.0% and 5.1-7.2%. The 24- and 48-h test results showed that the sample needed to be tested within 24 h. The limit of detection was 0.1 μg/kg for amitraz and 2,4-dimethylaniline, whereas for both the limit of quantitation was 0.3 μg/kg. © 2020 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.BACKGROUND Chronic rhinosinusitis (CRS) is a common post-radiotherapy (RT) side effect in patients with nasopharyngeal cancer (NPC). However, whether RT is a risk factor for CRS in patients with other types of head and neck cancer remains unclear. This study investigated the association, if any, between CRS and RT in patients with head and neck cancer. METHODS This retrospective cohort study included the data of patients newly diagnosed as having head and neck cancer between January 1, 2005, and December 31, 2008, from the 2005 Longitudinal Health Insurance Database. Patients were categorized into the following groups according to the treatment regimens received RT alone (RT-alone), RT combined with other treatments (any-RT), and treatments without RT (no-RT). The outcome was the occurrence of CRS after treatment. RESULTS Of the 701 patients, 7% experienced CRS within 5 years after initial treatment. Patients were divided into subgroups according to different treatment policies, and the RT-alone group, any-RT group, and no-RT group had 5-year incidence of CRS of 12%, 9.3%, and 4.5%, respectively. Patients in the RT-alone and any-RT groups exhibited an increased risk of CRS compared with patients in the no-RT group (hazard ratio 6.76 and 2.91; 95% confidence interval 2.60 to 17.5 and 1.60 to 5.31, respectively). CONCLUSION This is the first nationwide population-based cohort study to evaluate the risk of posttreatment CRS in patients with head and neck cancer. Our findings indicate that RT is a major risk factor for CRS. Thus, physicians should consider this potential risk in patients with head and neck cancer after RT. © 2020 ARS-AAOA, LLC.AIMS Glomerular filtration rate is an important factor in management of heart failure (HF). Our objective was to validate eight creatinine-based equations for estimating glomerular filtration rate (eGFR) in an HF population against measured glomerular filtration rate. METHODS AND RESULTS One hundred forty-six HF patients (mean age 68 ± 13 years, mean left ventricular ejection fraction 45% ± 15) within a single-centre hospital that underwent 51 Cr-EDTA clearance between 2010 and 2018 were included in this retrospective study. eGFR was estimated by means of Cockcroft-Gault ideal and actual weight, the Modification of Diet in Renal Disease Study (MDRD), simplified MDRD with isotope dilution mass spectroscopy traceable calibration, the Chronic Kidney Disease Epidemiology Collaboration, revised Lund-Malmö, full age spectrum, and the Berlin Initiative Study 1. Mean measured glomerular filtration rate was 42 mL/min/1.73 m2 . Pearson's correlation coefficient (r) had the highest precision for MDRD (r = 0.9), followed by revised Lund-Malmö (r = 0.88). All equations except MDRD (mean difference -4.8%) resulted in an overestimation of the renal function. The accuracy was below 75% for all equations except MDRD.  https://www.selleckchem.com/pharmacological_epigenetics.html  CONCLUSIONS None of the exclusively creatinine-based methods was accurate in predicting eGFR in HF patients. Our findings suggest that more accurate methods are needed for determining eGFR in patients with HF. © 2020 The Authors.
