Cognitive enhancement: less sleep = more done?

In Make me… stay awake, the final part of an engaging series of three documentaries (following Make me… smart and Make me… live forever), Michael Mosley investigates the effects of sleep deprivation and ways in which these symptoms may be alleviated. As he puts it in the introduction to the film, he wants to know if there are ways of “conquering… my need and my urge for sleep” (01:40).

Several sections of the programme brought bioethical themes into sharp focus – including the use of model organisms in research (17:53-20:47) and the use of drugs to stay awake longer (26:42- end).

Blood & Guts – A History of Surgery: Fixing Faces

In the fourth part of the BBC 4 Blood and Guts series, Fixing Faces looks at the evolution of plastic surgery. True to form, Michael Mosley presents a graphic account of how brutal attempts to reconstruct patients’ diseased or damaged faces have led to a modern medical speciality which is now believe to be on the eve of the first full face transplant. This episode describes and illustrates the history of this area of surgery: showing the work of the 16th century Italian doctor Gasparis Taliacotii (00:05:06 – 00:18:02); the beginning of the Botox era (00:18:02 – 00:30:00); and the work of Sir Harold Gillies and Sir Archibald Mclndoe, who developed both surgical techniques and the need for psychological support for patients undergoing reconstructive facial surgery (00:30:00 – 00:50:00) (Please see this Student BMJ article – ‘A brief histoy of plastic surgery’).

This episode highlights two main ethical topics for discussion: functional Magnetic Resonance Imageing (fMRI) and Neuroethics (00: 01:54 – 00:05:06); and face transplants or facial allograft transplantation (00:50:00 – End).

Blood & Guts – A History of Surgery: Spare Parts

Blood & Guts – A History of Surgery: Spare Parts is the third part of the BBC Four documentary series about the “brutal, bloody and dangerous history of surgery” focusing on the development of transplant surgery. The documentary primarily gives a graphic account of the history of transplant surgery, in particular focusing on the work of Alexis Carrel (00:04:24 – 00:22:47),  Joseph E. Murray (00:22:47 – 00:45:32) and Sir Roy Calne (00:36:40 – 00:45:32). However both at the beginning (Start – 00:04:24) and the end of the programme (00:45:32 – End) Michael Mosley (Also seen in BBC’s documentary series Medical Mavericks) discusses some of the ethical concerns that may arise from transplant surgery. Mosley meets with two patients who have both had a hand transplant, however only one of the patients is able to keep his new hand as it illustrates the success and failure of the radical surgery.

Michael Mosley (00:02:00 - 00:04:24): "I'm really intrigued by David (patient because to me this is something more than just incredible surgery. The whole idea of living with a dead man's hand is one I find fascinating but also disturbing. A lot of people I've talked to are really freaked by the idea of having something like an arm transplant, its also true frankly of all the buts of the body that show like; noses, eyes, and faces probably the freakiest of them all. No other form of surgery impacts on our sense of self in quite the way transplants do. There is something profoundly strange about swoping body parts, melding your flesh with others. And these days there seems to be no limits."

Blood and Guts – Bleeding Hearts

Michael Mosley: “The heart possesses a mystique, a romance that sets it a part from any other organs. This difference helped make heart surgery an extremely dangerous procedure. Not just for the patient but also for any surgeon prepared to operate on it.”
