Article Abstract
Background: Improving basic infection control (IC) practices, diagnostics and anti-microbial stewardship (AMS) are key tools to handle antimicrobial resistance (AMR).
Materials And Methods: This is a retrospective study done over 6 years (2016-2021) in an oncology centre in North India with many on-going interventions to improve IC practices, diagnostics and AMS. This study looked into AMR patterns from clinical isolates, rates of hospital acquired infections (HAI) and clinical outcomes.
Results: Over all, 98,915 samples were sent for culture from 158,191 admitted patients. Most commonly isolated organism was E. coli (n = 6951; 30.1%) followed by Klebsiella pneumoniae (n = 5801; 25.1%) and Pseudomonas aeroginosa (n = 3041; 13.1%). VRE (Vancomycin resistant Enterococcus) rates fell down from 43.5% in Jan-June 2016 to 12.2% in July-Dec 2021, same was seen in CR (carbapenem resistant) Pseudomonas (23.0%-20.6%, CR Acinetobacter (66.6%-17.02%) and CR E. coli (21.6%-19.4%) over the same study period. Rate of isolation of Candida spp. from non-sterile sites also showed reduction (1.68 per 100 patients to 0.65 per 100 patients). Incidence of health care associated infections also fell from 2.3 to 1.19 per 1000 line days for CLABSI, 2.28 to 1.88 per 1000 catheter days for CAUTI. There was no change in overall mortality rates across the study period.
Conclusion: This study emphasizes the point that improving compliance to standard IC recommendations and improving diagnostics can help in reducing the burden of antimicrobial resistance.

Epigenetic modulation of Ceratorhiza hydrophila by 5-azacytidine enhances antifungal metabolite production: insights from antimicrobial, metabolic, genomic and computational analyses.

Background: The emergence of drug-resistant pathogens has stimulated the need for the development of new antimicrobial agents. Epigenetic modulation by suppressing epigenetic inhibitors, such as 5-azacytidine (5-aza), has been shown to activate silent biosynthetic gene clusters within a fungus and causes the production of novel secondary metabolites. This research examined this epigenetic modification strategy in the poorly studied filamentous fungus, Ceratorhiza hydrophila, which may help induce the additional production of bioactive compounds.

Background: Respiratory tract infection tests are increasingly available in primary care and are expected to expand in the future. However, there is limited understanding of clinicians' views on their benefits and how to effectively integrate them into daily clinical practice.
Objectives: The aim of this study was to explore healthcare professionals' views on using respiratory tract infection tests to safely reduce unnecessary antibiotic prescriptions for respiratory tract infections in primary care based on their experience in routine practice.

Malaria treatments are compromised by drug resistance, creating an urgent need to discover new drugs. We used a phenotypic high-throughput screening (HTS) platform to identify new antimalarials, uncovering three related pyrrole-, indole-, and indoline-based series with a shared α-azacyclic acetamide core. These compounds showed fast-killing activity on asexual blood-stage parasites, were not cytotoxic, and disrupted parasite intracellular pH and Na regulation similarly to cipargamin (KAE609), a clinically advanced inhibitor of the Na pump (ATP4).

With antimicrobial resistance as a worldwide public health concern, bacteriophage (phage) therapy (PT) may help treat bacterial infections. However, given its particularities compared with traditional small molecule drugs, there are variations in how it is regulated worldwide. Regulators are key players governing PT, yet their perspectives have been largely unexplored.
