AI Article Synopsis

  • This study investigates the causes and prevalence of specific pathogens in endophthalmitis patients at a hospital in Southwest China over a 9-year period, aiming to understand how environmental factors affect the disease.
  • Data from 2,712 fungal or bacterial strains shows that gram-positive bacteria are the most common culprits, with a notable resistance to levofloxacin compared to moxifloxacin, and trauma being the leading cause of infections.
  • The research highlights the importance of the identified pathogen in endophthalmitis and warns against using levofloxacin as a first-line treatment, noting that changes in metabolites can indicate a shift towards a more harmful pathogenic state under low oxygen conditions.

Article Abstract

Introduction: This study aims to delineate the etiology and prevalence of isolated pathogens, along with the clinical characteristics of endophthalmitis patients over a 9-year period at hospital in Southwest of China. Additionally, we investigating the metabolic and cellular processes related to environmental factors may offer novel insights into endophthalmitis.

Methods: We analyzed data pertaining to endophthalmitis patients treated at the Affiliated Hospital of Yunnan University from 2015 to 2023. According to our clinical data, we conducted an experiment based on transcriptomics and metabolomics analysis to verify whether environmental factors affect behavior of by culturating under oxic and microoxic condition.

Results: In this study, 2,712 fungi or bacteria strains have been analyzed, gram-positive bacteria constituted 65.08%, with being the most predominant species (25.55%). Ophthalmic trauma was the primary pathogenic factor for ocular infections. Regarding fluoroquinolones, exhibited the higher resistance rate to levofloxacin than moxifloxacin. Moreover, our investigation revealed that in microoxic environment increase in energy metabolism, amino acid metabolism, and membrane transport.

Conclusion: Our findings underscore the significance of as a crucial pathogen responsible for infectious endophthalmitis. It is crucial to exercise vigilance when considering Levofloxacin as the first-line drug for empiric endophthalmitis treatment. The metabolites alteration observed during the commensal-to-pathogen conversion under microoxic condition serve as a pivotal environmental signal contributing to metabolism remodeling, toward more pathogenic state.

The incidence of multiple magnetic foreign body (MMFB) ingestion in children is rising, which poses a serious risk for gastrointestinal tract injury. In the current study, the clinical characteristics were analyzed to enhance awareness among parents and caregivers, treatment experiences were summarized and discussed, and optimal treatment plans were identified. A retrospective analysis was performed on 130 pediatric patients with MMFB ingestion at the Children's Hospital Affiliated with Zhejiang University School of Medicine, between June 2016 and June 2023.

Foodborne pathogens have always been of public health concern and represent safety issues for food processors. These pathogens develop new ways to overcome antibiotics, survive in different environmental conditions, and the ability to reproduce in many hostile environments configure them as serious health hazards. Considering the huge number of microorganisms, three bacterial representatives were selected to provide a better knowledge about the question of which one is the worst enemy for humans, from the food industry point of view, taking into consideration their multiplication specificity, virulence, and resistance.

Importance: Doxycycline postexposure prophylaxis (doxyPEP) has been shown to decrease the incidence of bacterial sexually transmitted infections (STIs) among people assigned male sex at birth in clinical trials, but data from clinical practice are limited.

Objective: To describe early uptake of doxyPEP and evaluate changes in STI incidence following doxyPEP initiation.

Design, Setting, And Participants: This retrospective cohort study of adults (aged ≥18 years) dispensed HIV preexposure prophylaxis (PrEP) at Kaiser Permanente Northern California during November 1, 2022, to December 31, 2023, examined electronic health record data to compare HIV PrEP users dispensed and not dispensed doxyPEP and rates of bacterial STIs before and after starting doxyPEP.

Importance: Despite their importance to patients, health, and industry, the magnitude of investments in drug research and development (R&D) remain nebulous. New policies require more granular and transparent R&D cost estimates to better balance incentives for innovation and returns to developers.

Objective: To estimate per-drug R&D costs using a novel, reproduceable approach and to describe firm-level R&D costs per discrete unit of R&D activity (1 patient-month).

Importance: A high infection burden in early childhood is common and a risk factor for later disease development. However, longitudinal birth cohort studies investigating early-life infection burden and later risk of infection and antibiotic episodes are lacking.

Objective: To investigate whether early-life infection burden is associated with a later risk of infection and systemic antibiotic treatment episodes in childhood.
