In the post rotavirus vaccine era, norovirus (NoV) plays an increasingly important role in epidemic and sporadic gastroenteritis among children. This study was designed to provide an updated meta-analytic review of the prevalence of NoV among paediatric patients with gastroenteritis and to clarify the relationship between NoV infection and gastroenteritis. Systematic searches of the literature for potentially relevant studies were carried out from 1 January 2015 to 29 May 2020.The inverse variance method was chosen for weighting of the studies, and the random-effects model was used to analyse data. To determine the association between NoV infection and gastroenteritis in children, pooled odds ratio (OR) and its 95% confidence interval (CI) were computed for case-control studies. The pooled prevalence of NoV infection among 12,0531 children with gastroenteritis from 45 countries across the world was 17.7% (95% CI: 16.3%-19.2%). There were 28 studies with a case-control design, and the pooled prevalence of NoV infection among 11,954 control subjects was 6.7% (95% CI: 5.1%-8.8%). The pooled OR of the association of NoV infection and gastroenteritis was 2.7 (95% CI: 2.2-3.4).The most common NoV genotypes were GII.4 (59.3%) and GII.

Ulcerative colitis (UC) and Crohn's disease (CD) are two major forms of inflammatory bowel disease (IBD), which is an inflammatory disease.Studies have shown that adipose tissue and inflammation play important roles in the pathogenesis of IBD. C1q/TNF-related protein-3 (CTRP3) is a newly discovered adipokine playing a substantial role during inflammatory process, and for the first time in the present study, serum levels of this adipokine were measured in the UC and CD patients. This casecontrol study included 70 control, 50 UC, and 50 CD patients who were diagnosed by standard criteria. Serum levels of adiponectin, IL-6, TNF-α, TGF-β, and CTRP3 were evaluated using ELISA kits.

Background: Meningitis, is a potentially life-threatening condition that can rapidly progress to permanent brain damage, neurologic problems, and even death. Bacteria and viruses cause the great majority of meningitis disease in infants and children. CRP is used mainly as a marker of inflammation.Objective: This study was conducted to assess the diagnostic value of CSF-CRP levels for differentiating between septic (bacterial) and aseptic infantile meningitis.Methods: 49 hospitalized infants aged less than two months with suspected meningitis were enrolled in a cross-sectional analytic study. All of patients underwent lumbar puncture to obtain CSF. smears, cultures, cytological and biochemical analysis and latex agglutination testing were carried out on all CSF samples. Latex agglutination test was carried out on all CSF samples using a commercially available kit. CSF-CRP level of all infants was measured using the immunoturbidometric technique.Results: Of 49 infants in this study, 20 and 29 cases were diagnosed as septic and aseptic meningitis, respectively. The CRP levels were obtained as 0.95±0.68 mg/L in septic and 0.16±0.36 mg/L in aseptic meningitis groups and this difference was statistically significant (p<0.001) between the two groups (0.79±0.32 mg/L). Based on the ROC curve, cut off levels for CRP was obtained 0.17 mg/L. At this level, there was 95% sensitivity and 86% specificity to differentiate septic and aseptic meningitis.Conclusion: CSF-CRP has suitable diagnostic value in distinguishing between infantile bacterial from aseptic meningitis especially in cases of negative bacterial culture of the blood and spinal fluid.Keywords: C-reactive protein, cerebrospinal fluid, septic/aseptic meningitis, infant, diagnostic value.

The concentration of IL-6 and EPO levels of the cord plasma was higher in the premature newborns with IVH.
