Enhanced recovery protocols versus traditional methods after resection and reanastomosis in gastrointestinal surgery in pediatric patients
Background Enhanced recovery after surgery (ERAS) is a group of changes in perioperative care that represent a fundamental shift from the traditional management of the gastrointestinal (GI) surgical patient.Objective To compare the results of applying enhanced recovery after GI resection in children versus the traditional methods.Patients and methods This prospective study included 60 patients who underwent GI resectional surgery between February 2016 and February 2017 at our institution. The patients were divided into two groups: group A (30 patients) was managed with ERAS protocol and group B (30 patients) was managed with traditional methods. All the patients underwent standard hand-sewn technique of GI resection reanastomosis. The protocol of ERAS included no routine nasogastric tube, early diet advancement, minimization of narcotic analgesics, early ambulation, and physical rehabilitation.Results The most frequent cause of GI resection reanastomosis surgery was intussusception (33.3% in group A and 36.7% in group B). Patients in group A had a significant lower frequencies of postoperative fever (33.3 vs. 66.7%, P<0.01) and chest infection (26.7 vs. 60%, P<0.01). Moreover, group A showed a significant shorter postoperative length of hospital stay (4 ± 1.2 days in group A vs. 7.1 ±2.05 days in group B, P<0.001).Conclusion Adopting ERAS protocol for resectional GI surgery in pediatric patients should be encouraged as it is results in lower incidences of postoperative fever and chest infection and is associated with less postoperative length of hospital stay.Keywords: enhanced recovery after surgery, enteral nutrition, gastrointestinal surgery, length of hospital stay, pediatric surger
New metal complexes derived from diacetylmonoxime-n(4)antipyrinylthiosemicarbazone: Synthesis, characterization and evaluation of antitumor activity against Ehrlich solid tumors induced in mice
The present study aimed to synthesize new metal complexes of diacetylmonoxime-N(4)antipyrinylthiosemicarbazone ligand and evaluate their antitumor activity. New complexes with ferric, cobalt, nickel and copper ions were prepared. Elemental, 1H Nuclear magnetic resonance, Mass spectroscopy, Electron paramagnetic resonance, Fourier Transform InfraredSpectroscopy, Ultraviolet–visible and thermal gravimetricanalysis were used to characterize the obtained complexes 1–11. An in vivo tumor model was established to investigate the effect of the naked ligand and its metal complexes 2, 5 and 8. Ehrlich ascites carcinoma solid tumor was induced in mice through subcutaneous inoculation of Ehrlich ascites carcinoma cells. The volumes of the formed solid tumors, the alanine transaminase, aspartate transaminase, albumin concentration in the serum, as well as the levels of Ki67 and p53 proteins in tumor and liver tissues were detected. All the tested complexes, especially complex 5, possessed proliferative inhibition manifested as the reduction of the tumor volume, Alanine aminotransferase & Aspartate aminotransferase activity, and the level of the Ki67 protein. Additionally, they restored the albumin concentration to normal levels as well increased the level of pro-apoptotic p53 protein. In conclusion, the antitumor activity of the newly synthesized metal complexes against Ehrlich ascites carcinoma solid tumors was proved to be mediated by the inhibition of Ki67 and induction of p53 proteins
Epidemiology, practice of ventilation and outcome for patients at increased risk of postoperative pulmonary complications
BACKGROUND Limited information exists about the epidemiology and outcome of surgical patients at increased risk of postoperative pulmonary complications (PPCs), and how intraoperative ventilation was managed in these patients.
OBJECTIVES To determine the incidence of surgical patients at increased risk of PPCs, and to compare the intraoperative ventilation management and postoperative outcomes with patients at low risk of PPCs.
DESIGN This was a prospective international 1-week observational study using the ‘Assess Respiratory Risk in Surgical Patients in Catalonia risk score’ (ARISCAT score) for PPC for risk stratification.
PATIENTS AND SETTING Adult patients requiring intraoperative ventilation during general anaesthesia for surgery in 146 hospitals across 29 countries.
MAIN OUTCOME MEASURES The primary outcome was the incidence of patients at increased risk of PPCs based on the ARISCAT score. Secondary outcomes included intraoperative ventilatory management and clinical outcomes.
RESULTS A total of 9864 patients fulfilled the inclusion criteria. The incidence of patients at increased risk was 28.4%. The most frequently chosen tidal volume (VT) size was 500 ml, or 7 to 9 ml kg1 predicted body weight, slightly lower in patients at increased risk of PPCs. Levels of positive end-expiratory pressure (PEEP) were slightly higher in patients at increased risk of PPCs, with 14.3% receiving more than 5 cmH2O PEEP compared with 7.6% in patients at low risk of PPCs (P < 0.001). Patients with a predicted preoperative increased risk of PPCs developed PPCs more frequently: 19 versus 7%, relative risk (RR) 3.16 (95% confidence interval 2.76 to 3.61), P < 0.001) and had longer hospital stays. The only ventilatory factor associated with the occurrence of PPCs was the peak pressure.
CONCLUSION The incidence of patients with a predicted increased risk of PPCs is high. A large proportion of patients receive high VT and low PEEP levels. PPCs occur frequently in patients at increased risk, with worse clinical outcome
New antiproliferative cembrane diterpenes from the Red Sea sarcophyton species
The combination of liquid chromatography coupled to high resolution mass spectrometry (LC-HRESMS)-based dereplication and antiproliferative activity-guided fractionation was applied on the Red Sea-derived soft coral Sarcophyton sp. This approach facilitated the isolation of five new cembrane-type diterpenoids (1–5), along with two known analogs (6 and 7), as well as the identification of 19 further, known compounds. The chemical structures of the new compounds were elucidated while using comprehensive spectroscopic analyses, including one-dimensional (1D) and two-dimensional (2D) NMR and HRMS. All of the isolated cembranoids (1–7) showed moderate in vitro antiproliferative activity against a human breast cancer cell line (MCF-7), with IC50 ranging from 22.39–27.12 µg/mL. This class of compounds could thus serve as scaffold for the future design of anticancer leads

Burden and risk factors for Pseudomonas aeruginosa community-acquired pneumonia:a Multinational Point Prevalence Study of Hospitalised Patients
Pseudornonas aeruginosa is a challenging bacterium to treat due to its intrinsic resistance to the antibiotics used most frequently in patients with community-acquired pneumonia (CAP). Data about the global burden and risk factors associated with P. aeruginosa-CAP are limited. We assessed the multinational burden and specific risk factors associated with P. aeruginosa-CAP.
We enrolled 3193 patients in 54 countries with confirmed diagnosis of CAP who underwent microbiological testing at admission. Prevalence was calculated according to the identification of P. aeruginosa. Logistic regression analysis was used to identify risk factors for antibiotic-susceptible and antibiotic-resistant P. aeruginosa-CAP.
The prevalence of P. aeruginosa and antibiotic-resistant P. aeruginosa-CAP was 4.2% and 2.0%, respectively. The rate of P. aeruginosa CAP in patients with prior infection/colonisation due to P. aeruginosa and at least one of the three independently associated chronic lung diseases (i.e. tracheostomy, bronchiectasis and/or very severe chronic obstructive pulmonary disease) was 67%. In contrast, the rate of P. aeruginosa-CAP was 2% in patients without prior P. aeruginosa infection/colonisation and none of the selected chronic lung diseases. The multinational prevalence of P. aeruginosa-CAP is low.
The risk factors identified in this study may guide healthcare professionals in deciding empirical antibiotic coverage for CAP patients

Strong semilattices of topological groups
AbstractThe notion of partial groups and their basic properties have been given in [1,2]. In this paper, we introduce the concept of topological partial groups and discuss some of their basic properties. So, the category of topological partial groups Tpg, as objects, and the homomorphisms of topological partial groups, as arrows, have some deficiencies. To get over these deficiencies, we introduced the category of locally compact partial groups denoted by Lcpg. Finally, we introduced the category of strong semilattices of topological groups denoted by Sstg
