Attitudes towards the mixing of COVID-19 vaccinated and unvaccinated patients in multi-bed hospital rooms.

Aim: To explore patient and staff views about the mixing of COVID-19 vaccinated and unvaccinated patients in multi-bed hospital rooms.

Methods: We conducted a mixed methods study with paper surveys and structured interviews. Self-administered surveys were undertaken with inpatients on the general medicine, general surgery, orthopaedic and respiratory wards in Dunedin Public Hospital.

Nonchromosomal birth defects and risk of childhood acute leukemia: An assessment in 15 000 leukemia cases and 46 000 controls from the Childhood Cancer and Leukemia International Consortium.

Although recent studies have demonstrated associations between nonchromosomal birth defects and several pediatric cancers, less is known about their role on childhood leukemia susceptibility. Using data from the Childhood Cancer and Leukemia International Consortium, we evaluated associations between nonchromosomal birth defects and childhood leukemia. Pooling consortium data from 18 questionnaire-based and three registry-based case-control studies across 13 countries, we used multivariable logistic regression models to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the association between a spectrum of birth defects and leukemia.

Breastfeeding and risk of childhood brain tumors: a report from the Childhood Cancer and Leukemia International Consortium.

Purpose: Studies report mixed findings regarding the association of breastfeeding with childhood brain tumors (CBT), the leading causes of cancer-related mortality in young people. Our objective was to determine whether breastfeeding is associated with CBT incidence.

Methods: We pooled data on N = 2610 cases with CBT (including 697 cases with astrocytoma, 447 cases with medulloblastoma/primitive neuroectodermal tumor [PNET], 167 cases with ependymoma) and N = 8128 age- and sex-matched controls in the Childhood Cancer and Leukemia International Consortium.

Investigating attitudes and insights into the global warming impact of inhalers.

Introduction: Inhalers are commonly used in the management of respiratory diseases. The propellants used in pressurised metered dose inhalers (pMDIs) are potent greenhouse gases and carry a substantial global warming potential. Dry powder inhalers (DPIs) are propellant-free alternatives that have fewer consequences on the environment, while being equally effective.
