β-Lactam antibiotics are one of the most important antibiotic classes but are plagued by problems of resistance, and the development of new β-lactam antibiotics through side-chain modification of existing β-lactam classes is not keeping pace with resistance development. In this JOCSynopsis, we summarize small molecule strategies to overcome resistance to β-lactam antibiotics. These approaches include the development of β-lactamase inhibitors and compounds that interfere with the ability of the bacteria to sense an antibiotic threat and activate their resistance mechanisms.

Bacteriophages (phages) are increasingly viewed as a promising alternative for the treatment of antibiotic-resistant bacterial infections. However, the diversity of host ranges complicates the identification of target phages. Existing computational tools often fail to accurately identify phages across different bacterial species.

Background: Beta-lactams remain the first-line treatment of infections despite the increasing global prevalence of penicillin-resistant/non-susceptible strains. We conducted a cross-sectional household survey in a rural community in northern Vietnam in 2018-2019 to provide prevalence estimates of penicillin non-susceptible (PNSP) carriage and to investigate behavioural and environmental factors associated with PNSP colonization. The data presented will inform the design of a large trial of population-based interventions targeting inappropriate antibiotic use.

Introduction: () is becoming more resistant to antibiotics, and the implementation of individualized therapy is highly valuable for its eradication. This study aimed to investigate the efficacy and safety of individualized treatment guided by antibiotic susceptibility testing (AST) with a 10-day or 14-day course for the eradication of .
Methods: This was a prospective, open-label, single-center, quasi-randomized trial in which 220 participants were randomized into groups based on AST results as AST-10-day ( = 98) and AST-14-day ( = 112) treatment groups.

Objective: This report details the complexities of diagnosing and treating rapid-onset multisystemic hemophagocytic lymphohistiocytosis (HLH) during pregnancy, as evidenced by a fatal case in early pregnancy with severe hematological and obstetric complications.
Case Presentation: A 20-year-old pregnant woman in her second pregnancy presented at 8 weeks of gestation with abdominal pain, fever, and rectal bleeding. Laboratory tests revealed leukopenia, thrombocytopenia, and anemia, leading to immediate transfusion and intensive care unit admission.
This study, conducted between June 2022 and March 2023 in Dhaka, examined prevalence in 874 samples from vegetables, vegetable wash water, and hand swabs from vendors during summer and winter. Of the total samples, 782 (89.50%) tested positive for , with 95.
