Printing to Fight Antimicrobial Resistance Through Nano/Microstructured Platforms

The Chemical Record, EarlyView.
Additive manufacturing enables the rational design of structured antimicrobial platforms across multiple length scales, from nanofibrous scaffolds and droplet microreactors to 3D and 4D printed constructs. By engineering confinement, interfacial chemistry, and stimuli‐responsive release, these systems exert localized action through complementary ...

Preferential Selection of Low-Frequency, Lipopolysaccharide-Modified, Colistin-Resistant Mutants with a Combination of Antimicrobials in Acinetobacter baumannii

Microbiology Spectrum, 2022
Colistin, which targets lipopolysaccharide (LPS), is used as a last-resort drug against severe infections caused by drug-resistant Acinetobacter baumannii. However, A. baumannii possesses two colistin-resistance mechanisms.

Clinical Features and Outcomes of Chronic Otitis Media Complications: A 20‐Year Retrospective Study at a Tertiary Hospital

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective Chronic otitis media (COM) is a major public health concern, particularly in developing countries. Although complications have decreased with modern antibiotics, they still cause significant morbidity and mortality. This study analyzed the clinical features, bacteriological profiles, and treatment outcomes of COM complications at a ...

Clinical Use of Colistin Induces Cross-Resistance to Host Antimicrobials in Acinetobacter baumannii

mBio, 2013
The alarming rise in antibiotic resistance has led to an increase in patient mortality and health care costs. This problem is compounded by the absence of new antibiotics close to regulatory approval.

Role of Gram‐Negative Bacterial Infections in Acute‐On‐Chronic Liver Failure

Liver International, Volume 46, Issue 7, July 2026.
ABSTRACT Acute‐on‐chronic liver failure (ACLF) is a systemic disease characterised by an acute clinical deterioration of pre‐existing liver cirrhosis leading to multiple organ failure due to systemic inflammation. It may be triggered by the translocation of bacteria and bacterial compounds across the gut barrier.
