Correspondence Laminar flow: the better choice in orthopaedic implants – Authors' reply
We appreciate Paul Jutte and colleagues' comments on our systematic review of studies of the effect of laminar airflow ventilation on surgical site infections (SSI).1 One of their main concerns is the use of data obtained from national surveillance systems and registries, since these databases were not designed specifically to address whether laminar airflow systems decrease the risk of SSIs. In their comment, Weinstein and Bonten2 also highlighted the high amount of clinical and statistical heterogeneity of the studies included in our review.

About one-third of adults say they don't usually get enough sleep. Now, there's news of a link between quality of sleep and risk of dementia. Dr. Jon LaPook explains the science behind the new report.
A BRISK 10-minute walk each day could save millions of middle-aged Britons from an early death, research has found.
A SIMPLE scan can accurately predict whether someone will suffer a potentially fatal stroke.
CANCER can be prevented with regular physical activity, but millions in the UK are raising their risk of early death by walking at a brisk pace less than ten minutes a month.
STROKE risk could be predicted after experts developed a new and potentially life-saving MRI scan.
The World Health Organization said the leading cause of death is now lower respiratory tract infections. HIV/AIDS killed 760,000 Africans in 2015, and was the top cause since at least 2000.
The move, unveiled in a policy statement on Wednesday, comes amid a broad effort to battle dangerous superbugs which are becoming increasingly resistant to medication.
The phase information of a complex field is routinely obtained using coherent measurement techniques as, e.g., interferometry or holography. The obtained measurement result is subject to a 2 π ambiguity and is often referred to as wrapped phase. Phase-unwrapping algorithms (PUAs) are commonly ...
Inspection of defects with micrometer level on large aperture surfaces with hundreds of millimeters is one of the challenges in surface quality evaluation. Various microscopic imaging methods have been applied to inspecting the surface defects, while they are time-consuming for the small field of ...
