Incidence of Drug-Resistant Hospital-Associated Gram-Negative Bacterial Infections, the Accompanying Risk Factors, and Clinical Outcomes with Treatment.

Extensive drug resistance to bacterial infections in hospitalised patients is accompanied by high morbidity and mortality rates due to limited treatment options. This study investigated the clinical outcomes of single and combined antibiotic therapies in extensive (XDR), multidrug-resistant (MDR) and susceptible strains (SS) of hospital-acquired infections (HAIs). Cases of hospital-associated drug-resistant infections (HADRIs) and a few susceptible strains from hospital wards were selected for this study.

Anti-blastocystosis activity of antioxidant coated ZIF-8 combined with mesoporous silicas MCM-41 and KIT-6.

The biocompatible hybrid Zeolitic imidazolate framework-8 (ZIF-8)/structured silica nanocomposite can be loaded with antioxidants such as curcumin and resveratrol to offer multiple advantages of drug functionalization and structural stability. blastocystosis, an enteric parasite, has various outcomes and its treatment includes drugs which have side effects and do not result in a full cure. We aimed to design novel biocompatible nanocomposites containing natural antioxidant, resveratrol or curcumin and ZIF-8/mesoporous silica.

Low levels of soluble DPP4 among Saudis may have constituted a risk factor for MERS endemicity.

Most of the cases of Middle East respiratory syndrome coronavirus (MERS-CoV) were reported in Saudi Arabia. Dipeptidyl peptidase-4 (DPP4) was identified as the receptor for the virus. The level of soluble DPP4 (sDPP4) was found to be reduced in MERS-CoV infected patients while high levels of sDPP4 were suggested to be protective against MERS-CoV in animal models.

Pooled Specimen Testing Using Automated Cartridge-Based System for COVID-19: The Cost on Sensitivity.

Background: Pooled specimen screening for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can improve laboratory testing capacity. This study assessed the impact of pooling and retesting individual swabs on the overall detection rate and reduction in the frequency of retesting.

Methods: One hundred respiratory swabs specimens were tested individually and in pools of three or five samples using the Cepheid's Xpert Xpress SARS-CoV-2 test kit.

Microleakage and Bacterial Adhesion with Three Restorative Materials Used to Seal Screw-access Channels of Implant Abutments: An Study.

Background: Proper sealing of screw-access channels against microbial microleakage is advisable for the long-term success of screw-retained implant prosthesis.

Objective: This study aimed to compare the bacterial adhesion and microleakage with three restorative materials, namely, composite resin, acrylic resin and bis-acryl, that are used to cover the access channels of screw-retained implant prostheses, using polytetrafluoroethylene tape as a spacer material.

Materials And Methods: In this study, 18 titanium straight abutments (Hex-lock Zimmer) were torqued into implant analogs, which were then subdivided into three groups.

Investigation of nonsynonymous mutations in the spike protein of SARS-CoV-2 and its interaction with the ACE2 receptor by molecular docking and MM/GBSA approach.

COVID-19 is an infectious and pathogenic viral disease caused by SARS-CoV-2 that leads to septic shock, coagulation dysfunction, and acute respiratory distress syndrome. The spreading rate of SARS-CoV-2 is higher than MERS-CoV and SARS-CoV. The receptor-binding domain (RBD) of the Spike-protein (S-protein) interacts with the human cells through the host angiotensin-converting enzyme 2 (ACE2) receptor.

mCIM test as a reliable assay for the detection of CRE in the Gulf region.

Carbapenem resistant (CRE) are one of the leading causes of systemic and nosocomial infections and are multidrug-resistant organisms producing different carbapenemases. There are many genotypic and phenotypic methods for detecting the carbapenemases; however, there is a limitation for each. Modified carbapenem inactivation method (mCIM) assay is a recent phenotypic method which has been published by the Clinical and Laboratory Standards Institute.

Surgical site infections in a tertiary hospital over 10 years. The effect of hospital accreditation strategy implementation.

Objectives:   To analyze the rate of surgical site infections (SSIs), the type, and the frequency of the commonly-associated microorganisms. Methods: A retrospective study was conducted in King Fahd Hospital of the University, Al Khobar, Saudi Arabia between December 2018 and June 2019 comprising data from August 2008 to August 2018 from patients with culture-confirmed surgical site infection at a tertiary hospital. Results: Out of 2716 wound infection cases during the study period, a total of 289 patients were diagnosed with SSI.

Pattern of increased antimicrobial resistance of isolates in the Eastern Province of KSA.

Objectives: The antimicrobial resistance of species is increasing worldwide. This study was conducted to determine the pattern of antimicrobial susceptibility of species in a tertiary hospital from 2011 to 2018.

Association between Hepatitis C Virus Viremia and the rs12979860, rs2228145 and rs1800795 SNP (CT/AC/GG) Genotype in Saudi Kidney Transplant Recipients.

Background: Hepatitis C virus (HCV) is a major health problem, particularly in high-risk groups such as kidney transplant recipients, where it can adversely affect graft survival and increase the relative risk for mortality. Recently, the role of genetic variation among HCV patients in determining the outcome of infections has been under investigation.

Objective: To investigate the association of single-nucleotide polymorphisms (SNPs) rs12979860 (located within the interleukin-28B locus), rs2228145 (interleukin-6 receptor) and rs1800795 (interleukin-6 promoter) with HCV viremia in renal transplant patients.

Effect of Leaf Extract on Glucose Transporter 4 Translocation and Glucose Uptake in 3T3L1 Cell Line.

Background: Numerous synthetic drugs have been recommended as a remedy for diabetes, but their role in hypoglycemic effects are diverse. The side effects associated with these drugs due to their extended use led scientists to find unconventional medicines with no or little side effects.

Aim: This study was aimed at assessment of antidiabetic activities of methanolic extract of leaves by using 3T3L1 cell line.
