Recovery of culturable Streptococcus pyogenes from swabs stored at different temperatures

Improving our understanding of superficial Streptococcus pyogenes (Strep A) carriage and transmission necessitates robust sampling methods. Here, we compared the effect of storing swab samples in fridge (+4°C) and freezer (-20°C) conditions on the recovery of laboratory-cultured S. pyogenes.

Challenges and insights in self-swab surveillance for asymptomatic Streptococcus pyogenes carriage

Asymptomatic carriage of Streptococcus pyogenes (Strep A) may contribute to transmission, yet its role remains poorly understood and evidence on optimal detection methods is limited. While self-collected throat swabs are used in infectious disease surveillance, their value for identifying asymptomatic Strep A carriage in adults is uncertain. This pilot prospective cohort study, conducted at a Perth medical research institute between August and October 2024, assessed feasibility and acceptability of self-collection, with sensitivity as a secondary objective. 

Antimicrobial resistance in Staphylococcus aureus and Enterococci spp. isolates from bloodstream infections in Australian children, 2013 - 2021

Rising proportions of antimicrobial resistance (AMR) have been observed in both Staphylococcus aureus and Enterococcus spp. isolates.

The effect of comprehensive geriatric assessment on treatment decisions, supportive care received, and postoperative outcomes in older adults with cancer undergoing surgery

Surgery is an essential part of cancer treatment, particularly for localised solid tumours. Geriatric assessments (GA) with tailored interventions or comprehensive GA (CGA) can identify frailty factors and needs of older adults with cancer, assisting treatment decisions and care strategies to reduce postoperative complications. This systematic review summarises the effects of GA/CGA compared to usual care for older adults with cancer intended for surgery: their impact on treatment decisions, supportive care interventions, postoperative complications, survival, and health-related quality of life.

Acceptability and Implementation Challenges of Benzathine Penicillin G Secondary Prophylaxis for Rheumatic Heart Disease in Ethiopia: A Qualitative Study

Monthly intramuscular injections of benzathine penicillin G (BPG) remain the cornerstone of secondary prophylaxis for acute rheumatic fever and rheumatic heart disease (RHD). The barriers to successful delivery of BPG may be patient- or service-delivery-dependent.

Recommendations for Sun Protection in Children and Young People: A Systematic Review of Guidelines and Consensus Statements

Ultraviolet radiation is the leading preventable cause of skin cancer, and early-life exposure increases long-term risk. Despite this, guidelines on sun protection for children and young people are inconsistent. 

From random care to randomized clinical trials of patients with invasive streptococcal infections—research prioritisation and areas of equipoise

Life-threatening invasive infections caused by Streptococcus pyogenes and Streptococcus dysgalactiae subsp. equisimilis (SDSE) are unpredictable, frequently fatal, and are increasing in incidence globally. In the absence of evidence from randomized controlled trials (RCTs), clinical management for these conditions varies. Understanding current management approaches and areas of clinical equipoise will inform planning of feasible high-impact RCTs.

Healthy skin for children and young people with skin of colour starts with clinician knowledge and recognition: a narrative review

Skin conditions most frequently encountered in paediatric practice include infections, infestations, atopic dermatitis, and acne. Skin of colour refers to skin with increased melanin and darker pigmentation, and reflects global racial and ethnic diversity. Managing skin conditions in skin of colour requires health equity nuance, which is rarely explicitly taught. 

Establishing the lowest penicillin concentration to prevent pharyngitis due to Streptococcus pyogenes using a human challenge model (CHIPS)

The in-vivo plasma concentration of penicillin needed to prevent Streptococcus pyogenes pharyngitis, recurrent acute rheumatic fever, and progressive rheumatic heart disease is not known. We used a human challenge model to assess the minimum penicillin concentration required to prevent streptococcal pharyngitis.
