Background and Aim: Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in children and adolescents, and its prevalence increases with obesity. Magnetic resonance imaging (MRI) and transient elastography (TE) have been widely used to non-invasively evaluate NAFLD in adults. This study aimed to determine the efficacy and accuracy of MRI-proton density fat fraction (MRI-PDFF) and TE-controlled attenuation parameter (TE-CAP) in distinguishing hepatic steatosis in children and adolescents.Materials and Methods: In this meta-analysis, the PubMed, Cochrane Library, Embase, Medline, and Web of Science databases were searched for articles that reported studies on the accuracy of MRI-PDFF or TE-CAP in grading the steatosis in children and adolescents with NAFLD. This study compared the sensitivity, specificity, and hierarchical summary receiver operating characteristic curves (HSROCs) of MRI-PDFF and TE-CAP in distinguishing between steatosis grades S0 and S1–3.Results: A total of eight articles involving 874 children and adolescents with NAFLD were included in this study. The proportions of steatosis grades were 5 and 95% for S0 and S1–3, respectively. MRI-PDFF accurately diagnosed S1–3 steatosis, with a summary sensitivity of 0.95 (95% CI, 0.92–0.97), specificity of 0.92 (95% CI, 0.77–0.98), and HSROC of 0.96 (95% CI, 0.94–0.98). Likewise, TE-CAP accurately diagnosed S1–3 steatosis, with a summary sensitivity of 0.86 (95% CI, 0.70–0.94), specificity of 0.88 (95% CI, 0.71–0.96), and HSROC of 0.94 (95% CI, 0.91–0.95). Following a “positive” measurement (over the threshold value) for S1–3, the corresponding post-test probabilities of MRI-PDFF and TE-CAP for the presence of steatosis reached 92 and 88%, respectively, at the pretest probability of 50%. When the values were below the mentioned threshold values (“negative” results), the post-test probabilities of MRI-PDFF and TE-CAP became 5 and 13%, respectively.Conclusion: Both MRI-PDFF and TE-CAP are highly accurate non-invasive methods to grade the hepatic steatosis in children and adolescents with NAFLD. Furthermore, MRI-PDFF is significantly more accurate in assessing steatosis grade than TE-CAP.Systematic Review Registration: PROSPERO, identifier: CRD42021220422.

ObjectiveInvestigating the mental health status of Chinese resident physicians during the 2019 new coronavirus outbreak.MethodsA cluster sampling method was adopted to collect all China-wide resident physicians during the epidemic period as the research subjects. The Symptom Checklist-90 self-rating scale was used to assess mental health using WeChat electronic questionnaires.ResultsIn total, 511 electronic questionnaires were recovered, all of which were valid. The negative psychological detection rate was 93.9% (480/511). Among the symptoms on the self-rating scale, more than half of the Chinese resident physicians had mild to moderate symptoms of mental unhealthiness, and a few had asymptomatic or severe unhealthy mental states. In particular, the detection rate of abnormality was 88.3% (451/511), obsessive-compulsive symptoms was 90.4% (462/511), the sensitive interpersonal relationship was 90.6% (463/511), depression abnormality was 90.8% (464)/511), anxiety abnormality was 88.3% (451/511), hostility abnormality was 85.3% (436/511), terror abnormality was 84.9% (434/511), paranoia abnormality was 86.9% (444/511), psychotic abnormalities was 89.0% (455/511), and abnormal sleeping and eating status was 90.8% (464/511). The scores of various psychological symptoms of pediatric resident physicians were significantly lower than those of non-pediatrics (p < 0.05).ConclusionThe new coronavirus epidemic has a greater impact on the mental health of Chinese resident physicians.

Background: Adenomyosis and endometriosis are often co-existent. Laparoscopic surgery is one of the main methods to diagnose and treat these conditions. However, very few studies have been done that concentrate on the pregnancy outcomes of infertile women with both adenomyosis and endometriosis after laparoscopic surgery, as well as the relevant influential factors.Methods: This is a retrospective, cross-sectional study including infertile women diagnosed with endometriosis and adenomyosis. All patients had undergone laparoscopic surgery and were divided into two groups according to pregnancy outcomes. Demographic data, operation records, and pregnancy outcomes were collected.Results: Ninety-seven patients had live births, including 81 full-term and 16 preterm deliveries. The biochemical pregnancy, clinical pregnancy, and live birth rates were 80.87%, 67.4, and 55.11% respectively. One hundred thirty-five patients received IVF with 70 (51.85%) patients having live births. Age, size of endometrioma, and size of uterus were significantly lower in those who had a successful delivery. There was no statistical difference in symptoms except anemia (13.40% vs. 25.32%, p=0.044). The group that failed to have a live birth had a higher percentage of ovarian and peritoneal endometriosis (P<.05), while the distribution of deep infiltrating endometriosis and adenomyosis types were similar. Mean uterus diameter (OR: 0.636, 95% CI: 0.434-0.932, p = 0.020) and endometriosis fertility index (EFI) (OR:1.299, 95% CI: 1.101-1.531, p = 0.002) were significantly correlated with live births in the multivariate analysis.Conclusions: Endometriosis and adenomyosis have an adverse effect on fertility. IVF is an important technology improving pregnancy rate even after surgery. The size of the uterus and EFI were independent risk factors for pregnancy outcomes.
