BACKGROUND: Infection by Staphylococcus aureus (S. aureus) is a major cause of morbidity and mortality. Colonization by S. aureus increases the risk of infection. Little is known about decolonization strategies for S. aureus beyond antibiotics, however probiotics represent a promising alternative. A randomized controlled trial was conducted to determine the efficacy of Lactobacillus rhamnosus (L. rhamnosus) HN001 in reducing carriage of S. aureus at multiple body sites. METHODS: One hundred thirteen subjects, positive for S...

BACKGROUND: Infection is the most significant complication in implant-based breast reconstruction, potentially leading to reconstructive failure. We hypothesized that implementation of an evidence-based protocol marked by preoperative decolonization and sterility optimization would result in a decline in postoperative infection rates. METHODS: Informed by a literature review, we developed an evidence-based, perioperative infection prevention protocol implemented in 2015...

Surgical site infections (SSI) are among the most important complications in knee arthroplasty. In this article we aim to retrospectively evaluate effects of preoperative multidisciplinary assessment and treatment of focal infections in primary knee arthroplasty patients operated by a single surgeon in a single center. A total of 93 patients undergoing 120 primary knee arthroplasty operations were included in the study. In the preoperative assessment all patients were consulted by infectious diseases, otorhinolaryngology (ENT) and dentistry departments, and female patients additionally by gynecology departments to evaluate and treat possible focal infections...

BACKGROUND: With increasing rates of virulent drug resistant organisms, MRSA (methicillin-resistant Staphylococcus aureus) decolonization has been demonstrated to decrease infection rates. Recent research has shown the antiseptic povidone-iodine to be equally effective and potentially cost saving compared to intranasal mupirocin. This study's purpose is to evaluate the incidence of MRSA colonization in a more rural community-based population, rates of infection on a mupirocin decolonization protocol, and develop a cost analysis model to compare costs of utilizing povidone-iodine...

BACKGROUND: Carbapenem-resistant Enterobacteriaceae (CRE) and Vancomycin-resistant enterococci (VRE) carriage is increasing worldwide. Fecal microbiota transplantation (FMT) appears to be an attractive option for decolonization. We aimed to evaluate CRE versus VRE clearance by FMT among carriers. METHODS: We performed a multicentre trial on patients with CRE or VRE digestive tract colonization who received FMT between January 2015 and April 2017. Adult patients with CRE or VRE colonization were included; confirmed by three consecutive rectal swabs at weekly intervals, including one in the week prior to FMT...

We recently discovered RnpA as a promising new drug discovery target for methicillin-resistant S. aureus (MRSA). RnpA is an essential protein that is thought to perform two required cellular processes. As part of the RNA degrasome Rnpa mediates RNA degradation. In combination with rnpB it forms RNase P haloenzymes which are required for tRNA maturation. A high throughput screen identified RNPA2000 as an inhibitor of both RnpA-associated activities that displayed antibacterial activity against clinically relevant strains of S...

Enterococci are commensal microorganisms present in the gastrointestinal (GI) tract of humans. Though normally innocuous to the host, strains of Enterococcus exhibiting resistance to vancomycin (VRE) have been associated with high rates of infection and mortality in immunocompromised patients. Decolonization of VRE represents a key strategy to curb infection in highly-susceptible patients. However, there is a dearth of decolonizing agents available clinically that are effective against VRE. The present study confirms that niclosamide, an anthelmintic drug, has potent antibacterial activity against clinical isolates of vancomycin-resistant E...

Introduction: Exacerbation of atopic dermatitis can be associated with bacterial infection. The skin of patients is colonized with Staphylococcus aureus in 90% of cases. An attempt has been made to demonstrate that eradication significantly reduces the severity of the disease. Studies indicate the efficacy of topical antibiotics, topical corticosteroids and calcineurin inhibitors. Due to increasing resistance to drugs and the defective antimicrobial peptide profile, decolonization is virtually impossible...

BACKGROUND: Several studies have shown that Staphylococcus aureus (S aureus) nasal colonization is associated with surgical site infection and that preoperative decolonization can reduce infection rates. Up to 30% of joint arthroplasty patients have positive S aureus nasal swabs. Patient risk factors for colonization remain largely unknown. The aim of this study was to determine whether there is a specific patient population at increased risk of S aureus nasal colonization. METHODS: This study is a retrospective review of 716 patients undergoing hip or knee arthroplasty beginning in 2011...

When working with clients in another language, having culturally relevant and properly translated clinic materials is vital to effective clinical practice. Not having them presents a barrier for bilingual therapists and their clients. This paper reviews common translation methods and introduces a multi-level, community-based approach for translating clinic materials for non-English speaking clients. Informed by decolonizing practices, this five-tier method includes members from the target community as cultural brokers to verify the accuracy and nuances of language for their cultural group, as well as a constant comparative method to ensure methodological rigor in the process of inclusion...

The purpose of this study was to determine if a decolonization regimen reduces the frequency of methicillin-resistant Staphylococcus aureus (MRSA) infections and if colonization isolates are genetically related to subsequent infectious strains. Trauma patients admitted to the intensive care unit with positive MRSA nasal swabs were randomized to either daily chlorhexidine gluconate (CHG) baths and mupirocin (MUP) ointment to the nares or soap and water baths and placebo ointment for five days. Nasal swabs performed at the end of treatment and invasive MRSA infections during the remaining hospitalization were compared with the original nasal isolate via polymerase chain reaction for genetic relatedness as well as CHG and MUP resistance genes...

KPC-producing Klebsiella pneumoniae (KPC-Kp) is nowadays a global concern. Ceftazidime/avibactam is the most promising novel antibiotic combination available at the moment. We describe the case of a migrant with no risk factors for an infection due to multidrug resistant bacteria. He suffered from a KPC-Kp cellulitis and was treated with a ceftazidime/avibactam-meropenem-fosfomycin combination that not only eradicated the infection but also decontaminated his gut. Ceftazidime/avibactam-based treatment can be useful also in decontamination procedures...

Staphylococcus aureus (SA) nasal carriage is transient in most humans and usually benign, but dissemination of SA to extranasal sites causes the majority of clinical infections, and SA is a major cause of serious infections in the U.S. A better understanding of innate nasal decolonization mechanisms is urgently needed, as are relevant models for studying SA clearance. Here, we screened a population of healthy smokers for nasal SA carriage, and compared participants' abilities to clear experimentally applied nasal SA before and after completion of a smoking cessation program...
