PURPOSE: Sepsis is a life-threatening organ dysfunction caused by dysregulated host response to infection. The purpose of the study was to measure the associations of specific exposures (deprivation, ethnicity, and clinical characteristics) with incident sepsis and case fatality. METHODS: Two research databases in England were used including anonymized patient-level records from primary care linked to hospital admission, death certificate, and small-area deprivation...

INTRODUCTION: Wound irrigation has been employed as an important surgical step to remove bacteria, devitalized tissues, and foreign bodies from surgical sites to prevent infection and confer to the wound maximum potential of healing. METHOD: A prospective study was conducted at Federal Medical Centre, Gusau, between January 2019- August 2023 to assess the benefit of antibiotics as additives in irrigation of dirty wounds. Seven (7) patients in total were presented with severe cut-throat injuries that require laryngopharyngoplasty...

Bacteriophage therapy is a rapidly growing field of study. Narrow host ranges, bacterial resistance, and limited antibiotic availability make lytic phages a feasible therapeutic potential. Phage discovery, a critical step in developing phage therapy, is a pathway to accessible treatment. This has always been a laborious, time-consuming and resource-intensive process. In this paper, we describe a 96-well plate low-volume bacteriophage enrichment method with concentrated environmental sources to rapidly discover and isolate phages targeting multiple organisms simultaneously...

BACKGROUND: There has been a notable decrease in antibiotic prescribing in the last thirty years in Sweden. Little is known about factors influencing antibiotic prescribing over several years. OBJECTIVE: To compare primary care physicians who, over time, reduced their antibiotic prescribing for respiratory tract infections with those who remained either high or low prescribers regarding potentially influencing factors. DESIGN AND SETTING: A register-based study including all RTI visits in primary care in Region Kronoberg, Sweden 2006-2014...

PURPOSE: Antibiotic overuse has increased over time related to provider knowledge gaps about best practices, provider perception of patient expectations on receiving an antibiotic, possible pressure to see patients in a timely fashion, and concerns about decreased patient satisfaction when an antibiotic is not prescribed. The Centers for Disease Control and Prevention estimates that up to 30% of antibiotics are inappropriately prescribed in the outpatient setting. APPROACH: This quality improvement project consisted of a multimodal approach to decrease inappropriate antibiotic prescribing for viral upper respiratory infections (URIs) by using provider education, passive patient education, and clinical decision support tools based on Centers for Disease Control and Prevention recommendations and the Be Antibiotic Aware tool...

Acute necrotizing pancreatitis is a common gastrointestinal disease requiring hospitalization and multiple interventions resulting in higher morbidity and mortality. Development of infection in such necrotic tissue is one of the sentinel events in natural history of necrotizing pancreatitis. Infected necrosis develops in around 1/3rd of patients with necrotizing pancreatitis resulting in higher mortality. So, timely diagnosis of infected necrosis using clinical, laboratory and radiological parameters is of utmost importance...

We investigated, by using all-atom molecular dynamics simulations, the effect of the asymmetric outer membrane layer of Gram-negative bacteria, composed in the outer leaflet by polar/charged lipopolysaccharides (LPS), on the electrostatic properties of general porins from the Enterobacteriaceae family. These porins constitute the main path for the facilitated diffusion of polar antibiotics to cross the outer membrane. As model system we selected OmpK36 from Klebsiella pneumoniae, the ortholog of OmpC from Escherichia coli...

The environmental dissemination of extracellular antibiotic resistance genes (eARGs) in wastewater and natural water bodies has aroused growing ecological concerns. The coexisting chemical pollutants in water are known to markedly affect the eARGs transfer behaviors of the environmental microbial community, but the detailed interactions and specific impacts remain elusive so far. Here, we revealed a concentration-dependent impact of dimethyl phthalate (DMP) and several other types of phthalate esters (common water pollutants released from plastics) on the natural transformation of eARGs...

Developing cost-effective and efficient photo-Fenton catalysts is crucial for advancing photo-Fenton technology. MoS2 is a representative transition metal disulfide with attractive photoresponsiveness, making it ideal for preparing composite photo-Fenton catalysts. In this study, natural molybdenite was innovatively utilized as a source of MoS2 (OM) to synthesize a low-cost and efficient Fe@MoS2 (OMF) composite photo-Fenton catalyst by comminution and adsorption, which was then applied to the remediation of antibiotic-contaminated water...

Neonatal meningitis is a devastating disease associated with high mortality and neurological sequelae. Escherichia coli is the second most common cause of neonatal meningitis in full-term infants (herein NMEC) and the most common cause of meningitis in preterm neonates. Here, we investigated the genomic relatedness of a collection of 58 NMEC isolates spanning 1974-2020 and isolated from seven different geographic regions. We show NMEC are comprised of diverse sequence types (STs), with ST95 (34.5%) and ST1193 (15...

Lyophilized Streptococcus spp. isolates (n = 50) from animal samples submitted to the diagnostic laboratory at the University of Connecticut in the 1940s were revivified to investigate the genetic characteristics using whole-genome sequencing (WGS). The Streptococcus spp. isolates were identified as follows; S. agalactiae (n = 14), S. dysgalactiae subsp. dysgalactiae (n = 10), S. dysgalactiae subsp. equisimils (n = 5), S. uberis (n = 8), S...

BACKGROUND: Fee-for-service is a common payment model for remunerating general practitioners (GPs) in OECD countries. In Norway, GPs earn two-thirds of their income through fee-for-service, which is determined by the number of consultations and procedures they register as fees. In general, fee-for-service incentivises many and short consultations and is associated with high service provision. GPs act as gatekeepers for various treatments and interventions, such as addictive drugs, antibiotics, referrals, and sickness certification...

This study aimed to explore the role of the two-component system Bae SR in the mechanism of drug resistance in carbapenem-resistant A. baumannii (CRAB) using molecular docking and real-time polymerase chain reaction (PCR). The two-component system Bae SR of Acinetobacter baumannii was subjected to molecular docking with imipenem, meropenem, and levofloxacin. Antibacterial assays and fluorescence quantitative PCR were used to explore protein-ligand interactions and molecular biological resistance mechanisms related to CRAB...

Bacterial resistance and excessive inflammation are common issues that hinder wound healing. Antimicrobial peptides (AMPs) offer a promising and versatile antibacterial option compared to traditional antibiotics, with additional anti-inflammatory properties. However, the applications of AMPs are limited by their antimicrobial effects and stability against bacterial degradation. TFNAs are regarded as a promising drug delivery platform that could enhance the antibacterial properties and stability of nanodrugs...

PURPOSE: The purpose of the study was to measure the association/s between OI location and risk for sepsis at admission. STUDY DESIGN, SETTING, AND SAMPLE: This retrospective cohort study included subjects treated for OI at Baylor University Medical Center in Dallas, TX, from January 9, 2019 to July 30, 2022...

BACKGROUND: Community-acquired and nosocomial lower-respiratory-tract infections in critically ill pediatric patients require early appropriate antibiotic therapy to optimize outcomes. Using blind bronchial samples, we assessed the diagnostic performance of the rapid-multiplex polymerase chain reaction (PCR) assay BioFire Pneumonia plus Panel vs. reference standard culturing with antimicrobial susceptibility testing. METHODS: For this prospective observational study in a single pediatric intensive care unit, we included consecutive patients younger than 18 years admitted for suspected community-, hospital- or ventilator-associated pneumonia in 2021-2022...

Peptidoglycan synthesis is an underutilized drug target in Mycobacterium tuberculosis ( Mtb ). Diazabicyclooctanes (DBOs) are a class of broad-spectrum β-lactamase inhibitors that also inhibit certain peptidoglycan transpeptidases that are important in mycobacterial cell wall synthesis. We evaluated the DBO durlobactam as an inhibitor of BlaC, the Mtb β-lactamase, and multiple Mtb peptidoglycan transpeptidases (PonA1, LdtMt1 , LdtMt2 , LdtMt3 , and LdtMt5 ). Timed electrospray ionization mass spectrometry (ESI-MS) captured acyl-enzyme complexes with BlaC and all transpeptidases except LdtMt5 ...

There is growing concern about the transfer of antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs) in airborne particulate matter. In this study, we investigated the effects of various types of carbonaceous particulate matter (CPM) on the transfer of ARGs in vitro . The results showed that CPM promoted the transfer of ARGs, which was related to the concentration and particle size. Compared with the control group, the transfer frequency was 95.5, 74.7, 65.4, 14.7, and 3.8 times higher in G (graphene), CB (carbon black), NGP (nanographite powder), GP1...

SIGNIFICANCE: The Wound Healing Foundation recognized the need for consensus-based unbiased recommendations for the treatment of wounds. As a first step, a consensus on the treatment of chronic wounds was developed and published in 2022.(1) The current publication on acute wounds represents the second step in this process. Acute wounds may result from any number of conditions, including burns, military and combat operations, and trauma to specific areas of the body. The management of acute wounds requires timely and evidence-driven intervention to achieve optimal clinical outcomes...
