        Subcutaneous infusion of high-dose benzathine penicillin G is safe, tolerable, and suitable for less-frequent dosing for rheumatic heart disease secondary prophylaxis: a phase 1 open-label population pharmacokinetic study

        Since 1955, the recommended strategy for rheumatic heart disease secondary prophylaxis has been benzathine penicillin G injections administered intramuscularly every 4 weeks. Due to dosing frequency, pain, and programmatic challenges, adherence is suboptimal. It has previously been demonstrated that BPG delivered subcutaneously at a standard dose is safe and tolerable and has favorable pharmacokinetics, setting the scene for improved regimens with less frequent administration. ...

        among children with pneumonia using a causal Bayesian network

        Pneumonia remains a leading cause of hospitalization and death among young children worldwide, and the diagnostic challenge of differentiating bacterial from non-bacterial pneumonia is the main driver of antibiotic use for treating pneumonia in children. Causal Bayesian networks (BNs) serve as powerful tools for this problem as they provide clear maps of probabilistic relationships between variables and produce results in an explainable way by incorporating both domain expert knowledge and numerical data. ...

        Morbidity of Scabies in Resource-Limited Countries: Rheumatic Heart Disease (RHD) and Post-Streptococcal Glomerulonephritis (APSGN)

        Scabies is one of the world’s most prevalent diseases, with approximately 147 million cases at any one time and an estimated annual incidence of 455 million new episodes. Although Group A streptococcal (GAS) pharyngitis has long been implicated in the pathogenesis of acute rheumatic fever (ARF) and subsequent rheumatic heart disease (RHD), impetigo caused by GAS has recently been postulated as a link between scabies and the pathogenesis of ARF. ...

        Evaluation of the implementation and clinical effects of an intervention to improve medical follow-up and health outcomes for Aboriginal children hospitalised with chest infections

        Aboriginal children hospitalised with acute lower respiratory infections (ALRIs) are at-risk of developing bronchiectasis, which can progress from untreated protracted bacterial bronchitis, often evidenced by a chronic (>4 weeks) wet cough following discharge. We aimed to facilitate follow-up for Aboriginal children hospitalised with ALRIs to provide optimal management and improve their respiratory health outcomes. ...

        Core protocol for the adaptive Platform Trial In COVID-19 Vaccine priming and BOOsting (PICOBOO)

        The need for coronavirus 2019 (COVID-19) vaccination in different age groups and populations is a subject of great uncertainty and an ongoing global debate. Critical knowledge gaps regarding COVID-19 vaccination include the duration of protection offered by different priming and booster vaccination regimens in different populations, including homologous or heterologous schedules. ...

        Stimulation of alpha-1 adrenoceptors may intensify cutaneous inflammation in complex regional pain syndrome

        Alpha-1 adrenoceptors are overexpressed in the epidermis of a subgroup of patients with complex regional pain syndrome. Activating α 1 -adrenoceptors in epidermal cells increases production of the proinflammatory cytokine interleukin-6, a mediator of inflammation. ...

        Modalities of group A streptococcal prevention and treatment and their economic justification

        Infection by group A Streptococcus (Strep A) results in a diverse range of clinical conditions, including pharyngitis, impetigo, cellulitis, necrotising fasciitis, and rheumatic heart disease. In this article, we outline the recommended strategies for Strep A treatment and prevention and review the literature for economic evaluations of competing treatment and prevention strategies. ...

        Verschlimmbesserung: Craniospinal Radiotherapy Is Essential in WNT Medulloblastoma Patients

        Standard-risk WNT medulloblastoma patients have an excellent prognosis using the combination of standard dose craniospinal radiotherapy (CSI) followed by platinum and alkylator based chemotherapy. A recent pilot study that attempted to completely omit radiotherapy was terminated early as all patients relapsed rapidly. The study highlights that therapy is the most important prognostic factor, with CSI still required to cure even the most favorable subgroup of medulloblastoma patients.  ...

        Intravascular Tumor Extension and Pulmonary Tumor Embolism in Children With Solid Malignancies: Is There a Role for Inferior Vena Cava Filters?

        Intravascular tumor extension is an uncommon complication of solid malignancies that, when present in the inferior vena cava (IVC), can result in fatal pulmonary tumor embolism. Currently, neoadjuvant chemotherapy and surgery are the mainstays of treatment; however, there are no consensus guidelines for management.   ...

        Presence of onco-fetal neighborhoods in hepatocellular carcinoma is associated with relapse and response to immunotherapy

        Onco-fetal reprogramming of the tumor ecosystem induces fetal developmental signatures in the tumor microenvironment, leading to immunosuppressive features. Here, we employed single-cell RNA sequencing, spatial transcriptomics and bulk RNA sequencing to delineate specific cell subsets involved in hepatocellular carcinoma  relapse and response to immunotherapy.  ...

        Outcomes following intensive day rehabilitation for young people in Western Australia

        Intensive rehabilitation aims to improve and maintain functioning in young people who experience disability due to illness or injury. Day rehabilitation may have advantages for families and healthcare systems over inpatient models of rehabilitation.  ...
