Drug-resistant gram-negative bacterial infections in children in the Oceania region: review of the epidemiology, antimicrobial availability, treatment, clinical trial and pharmacokinetic

Gram-negative bacterial infections remain a major cause of morbidity and mortality in children and neonates globally, compounded by the rise of antimicrobial resistance. Barriers to paediatric antibiotic licencing lead to reduced availability of potentially effective agents for treatment. For children and neonates in the Oceania region, specific challenges remain including a paucity of surveillance data on local rates of antimicrobial resistance, and lack of availability of newer, more costly agents.

The Association Between Obesity and COVID-19 Severity in Children Differed Between SARS-CoV-2 Variants: A Multicountry Hospital-based Observational Study

Obesity was a risk factor for severe COVID-19 in children during early outbreaks of ancestral SARS-CoV-2 and the Delta variant. However, the relationship between obesity and COVID-19 severity during the Omicron wave remains unclear.

Methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus faecium infections in children in the Oceania region

Antimicrobial resistance poses a significant threat to children's health, with up to 20% of 1.27 million deaths attributable to bacterial AMR annually, occurring in children <5 years. The WHO 2024 Bacterial Priority Pathogens List identifies methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus faecium (VRE) as critical pathogens. This review examines the epidemiology, treatment recommendations, dosing strategies, efficacy, and safety data for antibiotics targeting MRSA and VRE infections in children in Oceania.

The global, regional, and national burden of cancer, 1990–2023, with forecasts to 2050: a systematic analysis for the Global Burden of Disease Study 2023

Cancer is a leading cause of death globally. Accurate cancer burden information is crucial for policy planning, but many countries do not have up-to-date cancer surveillance data. To inform global cancer-control efforts, we used the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2023 framework to generate and analyse estimates of cancer burden for 47 cancer types or groupings by age, sex, and 204 countries and territories from 1990 to 2023, cancer burden attributable to selected risk factors from 1990 to 2023, and forecasted cancer burden up to 2050.

Preferences on the uptake and completion of single- or three-dose regimen of benzathine penicillin G injection for the treatment of late syphilis: a discrete-choice experiment

Notifications of syphilis in Australia have increased since 2011, particularly among gay and bisexual men who have sex with men (GBMSM). Adherence to current late latent syphilis treatment regimen is low-moderate, which is a significant health issue. To address this treatment non-compliance, a single high-dose benzathine benzylpenicillin G regimen has been under clinical trial.

Intranasal phage therapy overcomes antibody neutralization challenges in pulmonary Pseudomonas aeruginosa infections

Phage therapy is a promising approach against multidrug-resistant infections, yet systemic administration can lead to incomplete cures. We investigated the distribution, immune responses, and efficacy of the therapeutic phage KPP10 delivered via intranasal or intraperitoneal routes in murine Pseudomonas aeruginosa lung infection models.

Antimicrobial Resistance of Clostridioides (Clostridium) difficile in Cambodia

Antimicrobial resistance (AMR) remains a major topic of interest in infectious disease management. We studied AMR in Clostridioides difficile isolated in Cambodia.

Health impact and cost-effectiveness of COVID-19 booster vaccination strategies in the early post-Omicron era: a dynamic modelling study

Following widespread exposure to Omicron variants, SARS-CoV-2 has transitioned to endemic circulation. Populations now have diverse infection and vaccination histories, resulting in heterogeneous immune landscapes. Careful consideration of the value of ongoing vaccination is required through the post-Omicron phase of COVID-19 management to minimise disease burden.

Subcutaneous Infusion of Benzathine Penicillin G Is Acceptable and Preferred Over Intramuscular Injections for Syphilis in Western Australian Sexual Health Clinic Attendees

Controlling the syphilis epidemic in Australia is a public health priority. Regular intramuscular (IM) injections of benzathine penicillin G (BPG) are the current standard of care for late latent syphilis in Australia; however, repeated IM BPG injections are painful, and treatment completion rates are low. Early-phase clinical trials have demonstrated the tolerability and safety of high-dose subcutaneous infusions of BPG (SCIP), where the total treatment dose can be delivered at a single visit. Here we describe the experiences and preferences of attendees of Western Australian sexual health clinics in the Perth metropolitan region who have syphilis and were treated with SCIP.

Streptococcus pyogenes Surveillance Through Surface Swab Samples to Track the Emergence of Streptococcal Toxic Shock Syndrome in Rural Japan

Japan recently experienced a record surge in streptococcal toxic shock syndrome. Our environmental surveillance study reveals that Streptococcus pyogenes persists seasonally, peaking in autumn and winter in rural Japan. The dominant emm1 M1UK sublineage and csrS mutations heighten virulence, highlighting the urgent need for targeted surveillance and interventions.
