  IU/mL) after 18months of tocilizumab treatment (1.6%; 1/64). This patient was immediately treated with entecavir, which prevented hepatitis flare-up.
 
  Tocilizumab is widely used in treating rheumatoid arthritis and has the potential to reduce the mortality rate among severe COVID-19 patients. However, HBV reactivation needs to be considered. HBsAg+ patients have a high risk of HBV reactivation, which could be prevented by antiviral prophylaxis.  https://www.selleckchem.com/products/ca-170.html  Although the risk of reactivation is low in HBsAg-/HBcAb+ patients, strict monitoring is necessary.

  In Crohn's disease (CD) few data are available on the usefulness of monitoring fecal calprotectin (FC) in the early postoperative setting. We assessed prospectively the accuracy of FC measured 3months after surgery to predict the risk of endoscopic postoperative recurrence (POR) within 1year after resection.
 
  In 55 consecutive CD patients who had undergone ileocolonic resection samples were collected 3months after surgery for measuring serum CRP and FC. Endoscopic POR was assessed by ileocolonoscopy within 6-12months (median 7months). Receiver operating characteristic (ROC) curves were generated to assess accuracy of the markers, to determine the best threshold and to calculate sensitivity, specificity, positive and negative predictive values.
 
  In contrast with median CRP levels, median FC concentrations measured 3months after surgery were significantly higher in patients who later experienced endoscopic POR (Rutgeerts ≥ i2) compared with those who stayed in endoscopic remission within the following 6-12months (205μg/g IQR [106-721] vs. 103μg/g IQR [60-219], p = 0.008). Area under the ROC curve for FC was 0.71. The best cutoff value of FC to identify patients in subsequent endoscopic remission 3months after surgery was 65μg/g (96% sensitivity, 31% specificity, 50% positive and 91% negative predictive values). In multivariate analysis, FC < 65µg/g at 3months was the only factor associated with subsequent endoscopic remission.
 
  FC measured 3months after surgery below 65μg/g is an accurate marker to identify CD patients who will later stay in endoscopic remission within 1year after resection.

This study was performed retrospectively on CSF and serum samples collected from children evaluated for LNB (n = 233) and controls with other specific neurological disorders (n = 59) in a Swedish Lyme endemic area. For anti-Borrelia antibody index, the IDEIA Lyme Neuroborreliosis kit (Oxoid) was used. Two in-house real-time PCR assays targeting the 16S rRNA gene were evaluated (TaqMan® and LUX™). Among patients classified as LNB cases (n = 102), five children (5%) were Borrelia PCR-positive in CSF with the TaqMan® assay. In the Non-LNB group (n = 131), one patient was Borrelia PCR positive with the TaqMan® assay. Among controls (n = 59), all CSF samples were PCR negative. When amplifying and sequencing ospA, we found B. garinii (n = 2), B. afzelii (n = 2), B. bavariensis (n = 1), and one untypable (n = 1). With the LUX™ technology, all CSF samples were PCR negative. The TaqMan® assay could detect only few cases (n = 6) of B. burgdorferi s.l. in CSF among children with LNB and the sensitivity was very low (5%). However, using larger CSF volumes and centrifugation of samples, the PCR technique could still be useful as a complementary diagnostic method when evaluating LNB. Furthermore, detection of spirochete DNA in clinical matrices, including CSF, is the method of choice for studying epidemiological aspects of LNB, a tick-borne emerging disease.The T2 Candida Panel (T2CP) has high sensitivity and specificity to detect candidemia. Its role in the diagnosis and management of candidemia compared to blood cultures (BC) remains unclear. The purpose of this study was to evaluate the T2CP versus BC in detecting and treating candidemia. A retrospective, observational cohort study was conducted to compare clinical outcomes in patients with candidemia identified by BC versus T2CP. Patients with a positive BC or T2CP for Candida spp. from January 2012 to August 2020 were grouped by initial method of detection (BC vs T2CP). Co-primary endpoints assessed included time to detection of candidemia and time to antifungal therapy. Key secondary endpoints included length of stay (LOS), ICU LOS, and mortality. One hundred sixty-three patients with a positive BC and 89 patients with a positive T2CP were included in the evaluation. The average time to detection of candidemia was significantly shorter in the T2CP group compared to BC group (9 vs 41 h, p less then  0.001). The time to antifungal was also significantly shorter in the T2CP group compared to the BC group (4 vs 37 h, p  less then  0.001). However, LOS was significantly shorter in the BC positive group than the T2CP group with no difference in ICU LOS. There was no difference in in-hospital or 30-day mortality between the two groups. Of patients diagnosed with candidemia at our large community hospital, identification by T2CP led to faster detection and initiation of antifungal compared to blood cultures without improvement in LOS or mortality.
  Surgery for curable gastric cancer has historically involved dissection of lymph nodes, depending on the risk of metastasis. By establishing the concept of mesogastric excision (MGE), we aim to make this approach compatible with that for colorectal cancer, where the standard is excision of the mesentery.
 
  Current advances in molecular embryology, visceral anatomy, and surgical techniques were integrated to update Jamieson and Dobson's schema, a historical reference for the mesogastrium.
 
  The mesogastrium develops with a three-dimensional movement, involving multiple fusions with surrounding structures (retroperitoneum or other mesenteries) and imbedding parenchymal organs (pancreas, liver, and spleen) that grow within the mesentery. Meanwhile, the fusion fascia and the investing fascia interface with adjacent structures of different embryological origin, which we consider to be equivalent to the 'Holy Plane' in rectal surgery emphasized by Heald in the concept of total mesorectal excision. Dissecting these fasciae allows for oncologic MGE, consisting of removing lymph node-containing mesenteric adipose tissue with an intact fascial package.
