AIMS: Appendicitis is a common disease. The nationwide Danish National Patient Register provides an important data source for epidemiological research. Data used in register-based epidemiological research needs to be validated. We aimed to validate the diagnosis of appendicitis in the Danish National Patient Register. METHODS: From 1997 to 2015 nationwide data from the Danish National Patient Register, the Danish Pathology Register, and the Danish Civil Registration System were used to validate the diagnosis of appendicitis or the combination of the diagnosis for appendicitis and surgical removal of the appendix in the Danish National Patient Register...

BACKGROUND: Even in metropolitan areas, on-call pediatric surgeons may not always be immediately available for surgical care of appendicitis, potentially leading to delays in care. In 2012, the in-house trauma group at a suburban Level 1 trauma center (none with formal pediatric fellowship training) assumed surgical care of 5-10 year-old children with appendicitis, who had previously been cared for by pediatric surgeons. We propose to compare the outcomes of the trauma and pediatric surgery groups...

BACKGROUND: Transumbilical laparoscopic-assisted appendectomy (TULAA) is fast and cost-effective since no endoloops, staplers or wound protection devices are used. We analyzed the effects of TULAA as first approach for perforated (PA) and non-perforated (NPA) appendicitis in children. PATIENTS: We performed a retrospective analysis of 181 children for whom TULAA was the first approach for appendicitis between October 2010 and March 2016. METHODS: Morbidity, additional laparoscopic instrument insertion (AI), conversions to open extraumbilical appendectomy (OC), and complications were evaluated...

Described is the total synthesis of the myxobacterial natural product ripostatin B and of a small number of analogs. Ripostatin B is a polyketide-derived 14-membered macrolide that acts as an inhibitor of bacterial RNA-polymerase, but is mechanistically distinct from rifamycin-derived RNA-polymerase inhibitors that are in use for tuberculosis treatment. The macrolactone ring of ripostatin B features two stereocenters and a synthetically challenging doubly skipped triene motif, with one of the double bonds being in conjugation with the ester carbonyl...

The ground and excited state photophysical properties of a series of fac-[Re(L)(CO)3 (α-diimine)]n+ complexes, where L = Br- , Cl- , 4-dimethylaminopyridine (dmap) and pyridine (py) have been extensively studied utilizing numerous electronic and vibrational spectroscopic techniques in conjunction with a suite of quantum computational methods. The α-diimine ligand consists of 1,10-phenanthroline with the highly electron donating triphenylamine (TPA) appended in the 5 position. This gives rise to intra-ligand charge-transfer (ILCT) states lying lower in energy than the conventional metal-to-ligand charge-transfer (MLCT) state, the energies of which are red and blue-shifted, respectively, as the ancillary ligand, L becomes more electron withdrawing...

C-1027 is a chromoprotein enediyne antitumor antibiotic, consisting of the CagA apo-protein and the C-1027 chromophore. The C-1027 chromophore features a nine-membered enediyne core appended with three peripheral moieties, including an (S)-3-chloro-5-hydroxy--tyrosine. In a convergent biosynthesis of the C-1027 chromophore, the (S)-3-chloro-5-hydroxy--tyrosine moiety is appended to the enediyne core by the free-standing condensation enzyme SgcC5. Unlike canonical condensation domains from the modular nonribosomal peptide synthetases that catalyze amide bond formation, SgcC5 catalyzes ester bond formation, as demonstrated in vitro, between SgcC2-tethered (S)-3-chloro-5-hydroxy-β-tyrosine and (R)-1-phenyl-1,2-ethanediol, a mimic of the enediyne core as an acceptor substrate...

BACKGROUND: It is unclear if location of disease matters in perforated diverticulitis. Management guidelines for perforated diverticulitis currently do not make a distinction between right perforated diverticulitis (RPD) and left perforated diverticulitis (LPD). We aim to compare disease presentation and management outcomes between RPD and LPD. METHODS: This was a 10-year retrospective comparative cohort study of 99 patients with acute perforated diverticulitis between 2004 and 2013 in a single institution...

INTRODUCTION: Medium-term intravenous access in children is normally achieved by means of repeated multiple peripheral intravenous cannula insertions or peripherally inserted central catheters. Long peripheral cannulas might offer an alternative to these devices in children. Our aim was to clarify whether long peripheral cannulas provide reliable medium-term intravenous access avoiding the need for multiple peripheral intravenous cannulations or peripherally inserted central catheter insertion in children undergoing surgery...
