In the last two decades, the non-motor functions of the cerebellum have become the centre of attention for researchers. Anecdotal observations of cognitive and psychiatric manifestations of cerebellar lesions have increased this interest. We aimed to investigate the executive function (EF), intellectual capacity, and comorbid psychiatric disorders in adolescents with Chiari malformation type 1 (CM1), which is a pathological manifestation of posterior cranial fossa structures include the cerebellum.
 
  The Chiari group consisted of ten adolescents aged 12-18 years old, and the control group consisted of 13 healthy adolescents with similar age and sex with patients. Stroop test (ST), trail making test (TMT), and Behaviour Rating Inventory of Executive Function-Parent form (BRIEF) were used to evaluate EF; Kent EGY and Porteus Maze Test was used to measuring the intelligence quotient (IQ), and a semi-structured interview was used to determine the psychiatric disorders.
 
  EF test scores were found comparable between the two groups. IQ scores of the Chiari group were found in the normal range, but significantly lower than controls. No significant difference was revealed in terms of comorbid psychiatric disorders between the two groups.
 
  In this study, we did not observe an impairing effect of CM1 on EF and intelligence. Also, we found that CM1 did not cause more psychiatric disorders compared to controls. Further studies need to support our findings in adolescents diagnosed with CM1.

  Coronavirus disease 2019 (COVID-19) is a world-wide pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). To date, treatment of severe COVID-19 is far from clear. Therefore, it is urgent to develop an effective option for the treatment of patients with COVID-19. Most patients with severe COVID-19 exhibit markedly increased serum levels of pro-inflammatory cytokines, including interferon (IFN)-α, IFN-γ, and interleukin (IL)-1β.  https://www.selleckchem.com/products/lenalidomide-s1029.html  Immunotherapeutic strategies have an important role in the suppression of cytokine storm and respiratory failure in patients with COVID-19.
 
  A systematic search in the literature was performed in PubMed, Scopus, Embase, Cochrane Library, Web of Science, as well as Google Scholar preprint database using all available MeSH terms for Coronavirus, SARS-CoV-2, anti-rheumatoid agents, COVID-19, cytokine storm, immunotherapeutic drugs, IFN, interleukin, JAK/STAT inhibitors, MCP, MIP, TNF.
 
  Here, we first review common complications of COVID-19 patients, particula of immunosuppressant therapy is their inhibitory effects on host anti-viral immune response. So, the appropriate timing of administration should be carefully considered.
  The perforation of the upper gastrointestinal tract is still associated with a high risk of complications and mortality. We aimed to evaluate the optimal treatment and post-treatment complications for this condition.
 
  This was a retrospective, single-center study conducted between 2010 and 2019. We analyzed 50 patients with intraperitoneal free air caused by peptic ulcer (44 cases) or cancer (six cases).
 
  All patients initially received either conservative therapy (n = 7) or surgery (n = 43). The nonsurgically cured patients were significantly younger and had mild peritonitis and also had a shorter hospital stay. Two patients were converted to surgery due to worsening symptoms, and one of them was elderly and had a long perforation-to-treatment time. Regarding postoperative complications, patients with Grade II-V (n = 21) were significantly older and had a poorer physical status, longer perforation-to-surgery time, and higher preoperative CRP and lactate than those with Grade 0-I (n = 24). Multivariable analyses identified elevated preoperative lactate as an independent risk factor for postoperative complications. The patients with noncurative surgery for perforated advanced gastric cancer all died within 1year after surgery.
 
  Consideration should be given to the nonsurgical indications in elderly and delayed treatment patients and the postoperative outcomes of patients with preoperatively elevated lactate levels.

  Only limited data are available on the risk of liver fibrosis in patients with rheumatoid arthritis on long-term methotrexate treatment. To assess the risk of liver fibrosis in patients with rheumatoid arthritis treated with methotrexate, non-invasive, ultrasound-based elastography [acoustic radiation force impulse (ARFI) imaging] was applied.
 
  In total, 119 patients were assessed using acoustic radiation force impulse (ARFI) imaging between July 2018 and April 2019. In a cross-sectional, single-centre study design, ARFI scores were compared between patient subgroups with (n = 65) and without (n = 54) methotrexate exposure. The main outcome variable was the mean fibrosis score as measured by the ARFI method. The mean shear wave velocity was calculated from 10 valid ARFI measurements for each patient. Inferential statistical analyses (between group) were performed using ANOVA for independent samples in the case of continuous outcome variables.
 
  Sixty-five patients with and fifty-four patients without MTX exposure were assessed using the ARFI elastography method. Participating patients on MTX medication (1.113m/s) showed ARFI scores that were comparable to those of participants without MTX exposure (1.062m/s); P = 0.228. The mean cumulative dose in the group of MTX-exposed patients was 3602mg.
 
  The mean value of the repeated determination of liver density using ARFI imaging did not differ significantly between the MTX-exposed and MTX-naive patients with RA. No increased rate of liver fibrosis was found among RA patients treated with MTX.
