AI Article Synopsis

  • As antibiotic resistance grows and new antibiotics are harder to develop, urgent measures are needed to combat serious bacterial and fungal infections.
  • Healthcare-associated infections (HAIs) are significant contributors to illness, death, and healthcare costs, driven largely by antibiotic usage.
  • There are promising vaccine candidates in advanced clinical stages for pathogens like C. difficile, S. aureus, and P. aeruginosa, along with other immune interventions like monoclonal antibodies being developed to prevent these infections.

Article Abstract

As antibiotic resistance increases and the rate of antibiotic development slows, it is becoming more urgent to develop novel approaches to prevent and mitigate serious bacterial and fungal infections. Healthcare-associated infections (HAIs), including those caused by Clostridium difficile, Staphylococcus aureus, Pseudomonas aeruginosa, Acinetobacter baumannii, carbapenem-resistant Enterobacteriaceae, and Candida species, are a major cause of morbidity, mortality, and healthcare costs. HAIs are also a key driver of antibiotic use. Vaccines directed toward these pathogens could help prevent a large number of HAIs and associated antibiotic use if administered to targeted populations. Despite numerous scientific and operational challenges, there are vaccine candidates in late-stage clinical development for C. difficile, S. aureus, and P. aeruginosa Basic, preclinical, and early clinical research to develop vaccines for other types of HAIs is also under way. In addition, other prophylactic immune interventions, such as monoclonal antibodies, for several of these pathogens are in advanced development. Here we describe the promise, challenges, and current pipeline of vaccines to prevent HAIs.

Rationale: Early detection, standardized therapy, adequate infrastructure and strategies for quality improvement should constitute essential components of every hospital's sepsis plan.

Objectives: To investigate the extent to which recommendations from the sepsis guidelines are implemented and the availability of infrastructure for the care of patients with sepsis in acute hospitals.

Methods: A multidisciplinary cross-sectional questionnaire was used to investigate sepsis care in hospitals.

HIV Vulnerability Typologies Among Adolescent Girls and Young Women in Lesotho: A Population-Based, Cross-Sectional, Latent Class Analysis.

J Assoc Nurses AIDS Care

January 2025

Cho-Hee Shrader, PhD, MPH, is a Postdoctoral Research Scholar and MS Nursing Student, Arizona State University, College of Nursing and Health Innovation, Phoenix, Arizona, USA.

Adolescent girls and young women ages 15-29 years (AGYW) living in Lesotho experience a disproportionate HIV burden. Using a household-based national survey in Lesotho, we conducted a three-step latent class analysis to identify typologies of AGYW most vulnerable to HIV infection. We first classified AGYW into HIV vulnerability groups based on self-reported sexual behaviors, then identified associations between typology and HIV diagnosis.

The US faces substantial demographic and geographic disparities in both HIV burden and access to pre-exposure prophylaxis (PrEP), an effective strategy to prevent HIV acquisition. Long-acting cabotegravir (CAB) is a novel, injectable PrEP option which demonstrated superior reduction in risk of HIV acquisition compared to daily-oral PrEP in the HPTN083 trial. We modelled the impact of increased PrEP initiations and the introduction of long-acting CAB on HIV incidence among men who have sex with men (MSM) in Atlanta, Georgia, a population with a high burden of HIV.

Background: Diaper dermatitis (DD, sometimes known as diaper rash or napkin dermatitis is one of the most prevalent skin infections that occur in the area covered by the diaper. Although diaper dermatitis can be seen in any patient wearing diapers, it is reported to be more common in infants aged 9-12 months. Approximately, 70% of infants and young children suffer from diaper dermatitis at some point during their diaper wearing years and up to 25% of children seek healthcare due to this case.

Multiplicity of type 6 secretion system toxins limits the evolution of resistance.

Proc Natl Acad Sci U S A

January 2025

Division of Evolution, Infection and Genomics, Faculty of Biology, Medicine and Health, University of Manchester, Manchester M13 9NT, United Kingdom.

The bacterial type 6 secretion system (T6SS) is a toxin-injecting nanoweapon that mediates competition in plant- and animal-associated microbial communities. Bacteria can evolve de novo resistance against T6SS attacks, but resistance is far from universal in natural communities, suggesting key features of T6SS weaponry may act to limit its evolution. Here, we combine ecoevolutionary modeling and experimental evolution to examine how toxin type and multiplicity in attackers shape resistance evolution in susceptible competitors.
