Coronavirus disease 2019 (COVID-19) mRNA vaccines are associated with an increased risk of myocarditis using hospital discharge diagnoses as an outcome. The validity of these register-based diagnoses is uncertain. ⋯ This validation of register-based diagnoses of myocarditis by manual patient record review confirmed the register diagnosis in 96% of cases and had high interrater reliability. Reclassification had only a minor impact on the incidence rate ratios for myocarditis following COVID-19 vaccination.

Increased microvascular density correlates with more advanced disease and unfavorable overall survival in non-Hodgkin lymphoma (NHL), suggesting that angiogenesis is important for disease progression. However, studies of anti-angiogenic agents in NHL patients, have generally not shown favorable outcomes. The aim of this study was to investigate whether plasma levels of a subset of angiogenesis-associated proteins are increased in indolent B-cell derived NHL (B-NHL) and to investigate whether the levels differ between patients with asymptomatic versus symptomatic disease. ⋯ The finding of increased plasma endostatin and GDF15 in patients with asymptomatic indolent B-NHL suggests that increased angiogenic activity is an early event in indolent B-NHL disease progression.

Stress-related biomarkers have the potential to provide objective measures of whether interventions directed at people with dementia (PWD) and their family caregivers (FCG) are successful. The use of such biomarkers has been limited by logistical barriers to sample collection. ⋯ This study demonstrates that music intervention was associated with lower morning saliva cortisol concentrations for FCGs.

Nitrous oxide, commonly known as 'laughing gas', has become a popular recreational drug. Whippets, small canisters containing gas in pressurized form, can be easily obtained from a food store. ⋯ Inhalation of nitrous oxide rarely causes pneumothorax, pneumomediastinum, and pneumopericardium. This case study highlights the potential dangers of recreational abuse of nitrous oxide.

The esophageal-tracheal Combitube (ETC) was developed for the management of difficult airways but can also be used for general anaesthesia. ⋯ We conclude that the Combitube may be used for short procedures requiring general anaesthesia, but the high rate of minor complications limits its value when other alternatives such as a laryngeal mask airway are available. The tested method appears safe regarding major complications, but minor complications are common. Adherence to recommended cuff volumes, experience with the ETC and limiting its use to surgeries lasting less than 2 h might reduce the rate of complications.
