The role of children in transmission of SARS-CoV-2 variants of concern within households: an updated systematic review and meta-analysis, as at 30 June 2022

Meta-analyses and single-site studies have established that children are less infectious than adults within a household when positive for ancestral SARS-CoV-2. In addition, children appear less susceptible to infection when exposed to ancestral SARS-CoV-2 within a household. The emergence of SARS-CoV-2 variants of concern (VOC) has been associated with an increased number of paediatric infections worldwide.

Factors influencing scar formation following Bacille Calmette-Guérin (BCG) vaccination

The prevalence of scar formation following Bacille Calmette-Guérin (BCG) vaccination varies globally. The beneficial off-target effects of BCG are proposed to be stronger amongst children who develop a BCG scar. Within an international randomised trial ('BCG vaccination to reduce the impact of coronavirus disease 2019 (COVID-19) in healthcare workers'; BRACE Trial), this nested prospective cohort study assessed the prevalence of and factors influencing scar formation, as well as participant perception of BCG scarring 12 months following vaccination.

The risk of intramuscular haematoma is low following injection of benzathine penicillin G in patients receiving concomitant anticoagulant therapy

Our local data supports continuing intramuscular injection of BPG in patients with rheumatic heart disease receiving anticoagulant medication

A population pharmacokinetic study of benzathine benzylpenicillin G administration in children and adolescents with rheumatic heart disease

Few children and adolescents receiving BPG as secondary prophylaxis will achieve concentrations >0.02 mg/L for the majority of the time between injections

Aboriginal children and penicillin injections for rheumatic fever: How much of a problem is injection pain?

We explore young Aboriginal people's and clinicians' experience of injection pain for the 10 years of penicillin injections young people are prescribed.

Acceptability of sonicated versus unsonicated reconstituted (powdered) benzathine penicillin G for rheumatic fever prophylaxis

Powdered benzathine penicillin G (BPG) crystals vary widely in size and shape and are larger and less uniform than crystals found in pre-mixed suspensions of BPG like Bicillin ® L-A.

Diabetic kidney disease in northwest Ethiopia: Prevalence and determinants among adults with type 2 diabetes

Diabetic kidney disease (DKD), mainly due to type 2 diabetes (T2DM) is the leading cause of end-stage kidney disease globally. However, DKD prevalence in sub-Saharan Africa, particularly Ethiopia, is underexplored, especially using reliable markers like quantified albuminuria and cystatin C based estimated glomerular equations (eGFR). This study aimed to assess DKD prevalence and associated factors using multiple diagnostic markers.

High dose, subcutaneous injections of benzathine penicillin G (SCIP) to prevent rheumatic fever: A single arm, phase IIa trial of safety and pharmacokinetics

This Phase-IIa trial evaluates the safety and pharmacokinetics of high-dose, 10 weekly subcutaneous injections of penicillin (SCIP) in young people with a history of acute rheumatic fever (ARF).
