Perceived noise in surgical wards and an intensive care area: an objective analysis

British Medical Journal
S BentleyH Dudley


An investigation of noise levels in a hospital ward, a cubicle off the ward, and an intensive therapy unit (ITU) showed that the noise levels in all three areas were higher than internationally recommended levels at all times of day. Loud noises above 70 dB(A) were common in all areas but especially the ITU. The noise pollution levels reached annoying values during the day in the ward and cubicle and during both the day and the night in the ITU. Equipment and conversations among the staff were the main causes of noise in the ITU. These noisy environments are unlikely to help patients recover. Although measures designed to eliminate noisy surfaces will help, making staff aware of the noise they create and the effects it has may be much more effective in reducing noise pollution.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.
