Staphylococcus aureus small-colony variants (SCVs) are unique phenotypic forms that significantly contribute to the development of chronic, recurrent, and treatment-refractory infections. These variants arise from metabolic defects, most commonly in the menadione, hemin, or thymidine biosynthetic pathways, leading to slow growth, atypical colony morphology, and altered virulence expression. The ability of these bacteria to persist… Continue reading Small-colony variants of #Staphylococcus aureus: hidden threat in chronic and recurrent #infections

Does #oral #hygiene prevents nosocomial #infections in hospitalized patients? A systematic review and meta-analysis
Background: This study aimed to evaluate the impact of oral hygiene (OH) with chlorhexidine (CHX) on the evolution of nosocomial infections (NI).Material and methods: Electronic searches were carried out in PubMed, Scopus, Cochrane Library, Web of Science, VHL, and Grey Literature databases. Randomized clinical trials were included. Methodological quality and risk of bias were assessed… Continue reading Does #oral #hygiene prevents nosocomial #infections in hospitalized patients?

Healthy #sleep patterns and risk of hospitalization for #infection: a large community-based cohort study
Sleep behaviours are potentially modifiable risk factors for infectious disease. However, little is known about the combined effects of multiple sleep factors on the risk of infections. We investigated the prospective associations of combined healthy sleep patterns with the risk of hospitalization for infection in 397,523 participants (mean (SD) age: 56.3 (8.1) years) from the… Continue reading Healthy #sleep patterns and risk of hospitalization for #infection: a large community-based cohort study
#Antibiotics Not Associated with Shorter Duration or Reduced Severity of Acute Lower #Respiratory Tract Infection
BackgroundAntibiotic use remains common for the treatment of lower respiratory tract infections. The objective of this study was to evaluate the impact of antibiotic use on the duration and severity of acute lower respiratory tract infection (LRTI).ParticipantsAdult patients presenting to US primary or urgent care sites with a chief complaint of cough and symptoms consistent… Continue reading #Antibiotics Not Associated with Shorter Duration or Reduced Severity of Acute Lower #Respiratory Tract Infection
Short Oral Antibiotic Therapy for Pediatric Febrile #Urinary Tract Infections: A Randomized Trial
Febrile urinary tract infection (fUTI) in well-appearing children is conventionally treated with a standard 10-day course of oral antibiotic. The objective of this study is to determine the noninferiority (5% threshold) of a 5-day amoxicillin-clavulanate course compared with a 10-day regimen to treat fUTIs.METHODSThis is a multicenter, investigator-initiated, parallel-group, randomized, controlled trial. We randomly assigned… Continue reading Short Oral Antibiotic Therapy for Pediatric Febrile #Urinary Tract Infections: A Randomized Trial
Silver─Gallium Nano-Amalgamated Particles as a Novel, Biocompatible Solution for #Antibacterial Coatings
Bacterial infections account for countless deaths globally. Antibiotics are the primary countermeasure; however, the alarming spread of antibiotic-resistant strains necessitates alternative solutions. Silver and silver compounds have emerged as promising antibacterial agents. However, issues related to cytotoxicity and genotoxicity of silver remain concern. To overcome these challenges, this proposes an easy-to-control and straightforward method to… Continue reading Silver─Gallium Nano-Amalgamated Particles as a Novel, Biocompatible Solution for #Antibacterial Coatings
Elucidating regulatory processes of intense #physical activity by multi-omics analysis
BackgroundPhysiological and biochemical processes across tissues of the body are regulated in response to the high demands of intense physical activity in several occupations, such as firefighting, law enforcement, military, and sports. A better understanding of such processes can ultimately help improve human performance and prevent illnesses in the work environment.MethodsTo study regulatory processes in… Continue reading Elucidating regulatory processes of intense #physical activity by multi-omics analysis
Fever integrates antimicrobial defences, inflammation control, and tissue repair in a cold-blooded vertebrate
Multiple lines of evidence support the value of moderate fever to host survival, but the mechanisms involved remain unclear. This is difficult to establish in warm-blooded animal models, given the strict programmes controlling core body temperature and the physiological stress that results from their disruption. Thus, we took advantage of a cold-blooded teleost fish that… Continue reading Fever integrates antimicrobial defences, inflammation control, and tissue repair in a cold-blooded vertebrate
Association between vitamin D supplementation and COVID-19 infection and mortality
Vitamin D deficiency has long been associated with reduced immune function that can lead to viral infection. Several studies have shown that Vitamin D deficiency is associated with increases the risk of infection with COVID-19. However, it is unknown if treatment with Vitamin D can reduce the associated risk of COVID-19 infection, which is the… Continue reading Association between vitamin D supplementation and COVID-19 infection and mortality
