Practice GuidelineExecutive summary of consensus clinical practice guidelines for the prevention of infection in patients with multiple myeloma.
Infection remains a significant contributor to morbidity and mortality in patients with myeloma. This guideline was developed by a multidisciplinary group of clinicians who specialise in the management of patients with myeloma and infection from the medical and scientific advisory group from Myeloma Australia and the National Centre for Infections in Cancer. In addition to summarising the current epidemiology and risk factors for infection in patients with myeloma, this guideline provides recommendations that address three key areas in the prevention of infection: screening for latent infection, use of antimicrobial prophylaxis and immunoglobulin replacement and vaccination against leading respiratory infections (severe acute respiratory syndrome coronavirus 2, influenza and Streptococcus pneumoniae) and other preventable infections. This guideline provides a practical approach to the prevention of infection in patients with myeloma and harmonises the clinical approach to screening for infection, use of prophylaxis and vaccination to prevent infectious complications.

Proton pump inhibitors and the risk of acquiring a penicillin allergy label.
The negative consequences of having a penicillin allergy label are well established. Penicillin allergy de-labelling improves healthcare outcomes; however, less attention is paid to modifying risk factors leading to penicillin allergy development. In this propensity score-matched retrospective cohort study, we used a de-identified population-based database (TriNetX Research Network) and examined the 30-day risk of acquiring a penicillin allergy label in patients using proton pump inhibitors (PPIs). We demonstrated a higher risk of acquiring a penicillin allergy label among PPI users compared to controls.

A Retrospective Comparison of Ultrasound Guided Percutaneous and Open Skeletal Muscle Biopsies.
Open skeletal muscle biopsy has been the mainstay of sample retrieval in patients with suspected muscle diseases. However, this technique is limited by surgeon and theatre availability, potentially resulting in delayed diagnosis and increasing hospital stay. ⋯ Ultrasound guided percutaneous muscle biopsies were performed faster and a wider range of muscles were targeted. However, this technique yielded smaller samples, which were non-diagnostic in 26% of cases. Increasing the needle gauge or number of passes may improve the diagnostic yield of this technique.

Machine learning models automate classification of penicillin adverse drug reaction labels.
There is a growing interest in the appropriate evaluation of penicillin adverse drug reaction (ADR) labels. We have developed machine learning models for classifying penicillin ADR labels using free-text reaction descriptions, and here report external and practical validation. ⋯ These models have practical applications in detecting individuals suitable for penicillin ADR evaluation. Implementation studies are required.

The incidence of venous thromboembolism (VTE) for non-hospitalised patients with coronavirus disease-2019 infection has not been very widely studied. 13 019 persons with a positive SARS-CoV-2 nucleic acid amplification test were identified. In total, 447 (0.2%) VTEs were identified in the study population, 293 (66%) of these were pulmonary embolisms. A positive SARS-CoV-2 test did not increase the risk for VTE in the univariate analysis (odds ratio (OR): 1.0, 95% confidence interval (CI): 0.69-1.4) or multivariable analysis (OR: 1.36, 95% CI: 0.93-1.97).
