Abdominopelvic computed tomography (APCT) is a commonly used staging investigation to detect asymptomatic metastasis in breast cancer including early breast cancer (EBC). This study aimed to assess the usefulness of APCT in breast cancers at each clinical stage.
 
  Patients with new or recurrent invasive breast cancer between January 2009 and December 2014 were included in the study. All staging APCT results were reviewed to evaluate its yield and false positive rate (FPR) and how many investigations are needed to confirm indeterminate results. Odds ratios (ORs) for positive APCT results were calculated for possible risk factors for asymptomatic metastasis.
 
  Sixty-five asymptomatic metastases were detected from 1002 APCTs, giving an overall yield of 6.5%. The overall false-positive rate was 14.9 % due to 149 indeterminate findings that were found not to be metastases after further investigations or observation. Whereas the APCTs have a low yield of 3.1% in EBC, but advanced breast cancer and recurrent breast cancer have a high incidence of asymptomatic metastases (13.8% and 16.3%, respectively). The most common cause of indeterminate findings was small liver nodules, including liver cysts and liver hemangiomas. Human epidermal growth factor receptor2 (HER2) status and tumor stage are most significant predictors for positive results of staging APCT scans with high ORs (3.9 and 3.7, respectively).
 
  Staging APCT is associated with a high incidence of FPRs and low yield, especially among EBCs. It is desirable to choose this investigation more selectively according to HER2 status and tumor stage.

Phosphenium and arsenium ions are fiercely reactive cationic species, the stabilization of which has been so far achieved in the condensed phase by dispersing the positive charge through electromeric conjugation with at least one electron-rich substituent (frequently amido groups). Although observed in the gas phase, the isolation of dicoordinate phosphenium and arsenium ions lacking such stabilizing ligands has eluded chemists for decades. Herein we show that by judicious choice of aromatic substituents, dicoordinate, donor-free, Lewis-superacidic phosphenium and arsenium ions can be kinetically stabilized. They feature singlet electronic ground states possessing a vacant p-orbital and an electron lone pair with predominantly s-character.
  The evaluation of the stage of liver fibrosis is essential in patients with chronic liver disease. However, due to the low quality of ultrasound images, the non-invasive diagnosis of liver fibrosis based on ultrasound images is still an outstanding question. This study aimed to investigate the diagnostic accuracy of a deep learning-based method in ultrasound images for liver fibrosis staging in multicentre patients.
 
  In this study, we proposed a novel deep learning-based approach, named multi-scale texture network (MSTNet), to assess liver fibrosis, which extracted multi-scale texture features from constructed image pyramid patches. Its diagnostic accuracy was investigated by comparing it with APRI, FIB-4, Forns and sonographers. Data of 508 patients who underwent liver biopsy were included from 4 hospitals. The area-under-the ROC curve (AUC) was determined by receiver operating characteristics (ROC) curves for significant fibrosis (≥F2) and cirrhosis (F4).
 
  The AUCs (95% confidence interval) of MSTNet were 0.92 (0.87-0.96) for ≥F2 and 0.89 (0.83-0.95) for F4 on the validation group, which significantly outperformed APRI, FIB-4 and Forns. The sensitivity and specificity of MSTNet (85.1% (74.5%-92.0%) and 87.6% (78.0%-93.6%)) were better than those of three sonographers in assessing ≥F2.
 
  The proposed MSTNet is a promising ultrasound image-based method for the non-invasive grading of liver fibrosis in patients with chronic HBV infection.

  Non-alcoholic fatty liver disease (NAFLD) increases morbidity and mortality. However, patients in biopsy-based cohorts are highly selected and the absolute risks of liver- and non-liver outcomes in NAFLD in population remains undefined. We analysed both liver-related and non-liver-related outcomes in Finnish population cohorts of NAFLD.
 
  We included 10993 individuals (6707 men, mean age 53.3±12.6years) with NAFLD (fatty liver index ≥60) from the Finnish population-based FINRISK and Health 2000 studies. Liver fibrosis was assessed by the dAAR score, and genetic risk by a recent polygenic risk score (PRS-5).  https://www.selleckchem.com/products/ono-7300243.html  Incident liver-related outcomes, cardiovascular disease (CVD), cancer and chronic kidney disease (CKD) were identified through linkage with national registries.
 
  Mean follow-up was 12.1years (1128069 person-years). The crude incidence rate of liver-related outcomes in NAFLD was 0.97/1000 person-years. The cumulative incidence increased with age, being respectively 2.4% and 1.5% at 20years in men and women aged 60years at baseline, while the relative risks for CVD and cancer were 9-16 times higher. The risk of CKD exceeded that of liver outcomes at a baseline age around 50years. 20-year cumulative incidence of liver-related outcomes was 4.3% in the high, and 1.5% in the low PRS-5 group. The dAAR score associated with liver outcomes, but not with extra-hepatic outcomes.
 
  The absolute risk of liver-related outcomes in NAFLD is low, with much higher risk of CVD and cancer, emphasizing the need for more individualized and holistic risk-stratification in NAFLD.

  Previous studies investigating the prevalence of celiac disease (CD) in individuals with autoimmune hepatitis (AIH) have shown highly variable results. We therefore aimed to examine the prevalence of CD in individuals with AIH.
 
  Two professional librarians searched PubMed, EMBASE, Cochrane and Web of Science Core Collection up until 7 February 2020. The search terms included 'celiac disease', 'celiac', 'transglutaminases', 'gluten', 'gliadin', 'EMA', 'TTG' and 'villous' combined with 'autoimmune', 'hepatitis', 'ANA', 'SMA' and 'LKM'. This search yielded 2419 unique publications. A systematic review based on the PRISMA guidelines resulted in 31 articles eligible for full text review. Fifteen articles were deemed relevant, with 8 being included in our main analysis. A fixed-effect inverse variance-weighted model was used, and heterogeneity was calculated.
 
  Our main analysis included 567 individuals with AIH from eight studies, where biopsy-verified CD (equivalent to Marsh III) was seen in 23 individuals (4.
