Trials of autologous bone marrow stem cells for heart disease

The report by Nowbar and colleagues (doi:10.1136/bmj.g2688) on the relation between the number of discrepancies observed in clinical trials of autologous bone marrow stem cells for ischaemic heart disease and ejection fraction includes shambolic and poorly conducted research that reflects poorly on every part of the research process.1 On average, trials with many errors show improved ejection fraction, while trials with no errors find no benefit. How should we react to this finding and what lessons can we learn? In An Essay on Criticism, Alexander Pope stated that “to err is human,” but surely there is no place for errors in development of evidence that will inform treatment decisions?2

Cochlear implants for children and adults with severe to profound deafness | 2-Clinical-need-and-practice | Guidance and guidelines | NICE

2.1 Hearing loss may be caused by interference with the transmission of sound from the outer to the inner ear (conductive hearing loss) or damage within the cochlea, the auditory nerve or auditory centres in the brain (sensorineural hearing loss). In adults the most common cause of sensorineural hearing loss is presbycusis. This is a progressive condition caused by the loss of function of hair cells in the inner ear, leading to deafness. Hearing loss in adults may also be caused by excessive exposure to noise, or by ototoxic drugs, metabolic disorders, infections or genetic factors. Severe to profound hearing loss in children may have a genetic aetiology, or have prenatal, perinatal or postnatal causes. These include conditions such as meningitis and viral infection of the inner ear (for example, rubella or measles), as well as premature birth and congenital infections. Deafness that occurs before the development of language is described as prelingual, whereas deafness that occurs after the development of language is described as postlingual.
