In this Al Jazeera Investigates documentary, former UK hurdler Liam Collins embarks on an undercover investigation seeking to expose ‘the dark side’ of professional sports; blood doping and the use of performance enhancing drugs (PEDs) by professional athletes. This 16-minute clip splices together key sections of the documentary (The full programme can be seen on YouTube as well as on Box of Broadcasts).

I can take a guy with average genetics and I can make him a world champion. I can with drugs. Oh absolutely.

The documentary stirred controversy, primarily for featuring accusations regarding several NFL footballers,  notably Peyton Manning, who went on to steer his Denver Broncos team to success at Superbowl 50 before announcing his retirement. More importantly, the documentary highlights loopholes in the drug testing regimes of several popular sports. Athletes play a ‘cat and mouse game’ with the testing system; timely drug administration combined with an awareness of testing procedures results in athletes coming up negative in tests.

Increasing global population and food demands drive the discovery for new food sources and imminent dietary change

Review by Ella Yabsley

This 4.5-minute clip from BBC Two’s Food & Drink could serve as a useful discussion-starter when considering the ethics of global meat consumption. The clip begins with the introduction of a new type of food source, cultured beef or in vitro meat (IVM). A  team from Maastricht University (Holland) claim that IVM was produced for numerous reasons: IVM is more sustainable compared to traditional animal farming practices; it could solve the current (and future) food crisis; and it could also help to combat climate change. Regardless of your ethical standpoint, this clip highlights some of the ethical, economic and health-related tensions that the ‘Western World’ is facing with regards to animal agriculture.

“They might be cute but the mess some dogs leave behind is unpleasant and can also be dangerous. That’s why Barking and Dagenham council in East London are doing this: encouraging dog owners to register their pets’ DNA.”

It may sound like a joke, but this clip from BBC Breakfast (6 minutes) covers the story on the latest plans by the East London Borough of Barking & Dagenham to combat the problem of dog mess on the streets. Aside from being unsightly, dog faeces on the street pose a health risk, mainly to young children, who could contract toxocariasis by unintentionally ingesting roundworm parasites after touching mud laced with faeces. Barking and Dagenham spend approximately £2.3million a year cleaning up dog excrement and, in times of austerity, it is increasingly important that this sum is reduced by encouraging people to pick up after their pets.

The borough have partnered with PooPrints®, a company specialising in the genetic analysis of dog waste to give residents the opportunity to have their dog’s DNA stored on a database. This would be of potential benefit to registering owners to allow them to identify their dog if it is lost or stolen. Most importantly, in the context of the story, it will eliminate their pet in inquiries into the identity of any dog whose faeces have been left in the street. If the owner is found, they will be sent a warning letter. If there is a second offense, then they will be fined £80. At the moment, the service is voluntary which could be a problem as some may be unwilling to potentially incriminate themselves. However, the service is free for the first 1,000 dogs, which could provide an incentive, and the suggestion is made that it might be factored into future rent agreements in order to be granted permission to use the local parks.

In this three minute clip, Fergus Walsh reports on a trial being conducted at Guy’s and St Thomas’ NHS Foundation Trust (London). The research, led by Prof Mark Peakman, is using a combination of protein fragments (MultiPepT1De) to try and trigger a “protective” immune response, rather than the inappropriate antibody production against islet cells that underlies Type 1 diabetes.

This link includes a video by Prof Peakman introducing the biochemistry of Type I diabetes and the basis of their research (5 mins). See also this article by Peakman on the principles behind the new approach.

Proton or photon? Cancer-bashing particles

Review by Ella Yabsley

A study published on the Lancet Oncology website in January 2016 reported that proton beam therapy was as effective as traditional photon radiotherapy for the treatment of paediatric medulloblastoma (a childhood brain cancer). The paper also suggests proton radiotherapy reduces toxicity towards normal tissues (compared to photon radiotherapy) and could improve long-term health outcomes for children with malignant brain cancer. At the present time, the NHS are paying for eligible patients to receive proton treatment abroad. From 2019, two new NHS proton beam therapy facilities will be opened in London and Manchester (more by private institutions).

This video file (11 mins), a combination of several shorter pieces from Breakfast News, gives background to the development including an interview with a paediatric oncologist who explains what the study does, and does not, show. It is a (relatively) large study but the observations appear not to be a surprise to those working in the field; the interest may be linked to the controversy surrounding the Ashya King case.

For people from an ethnic minority background like me and my family, finding yourself in a situation where you need an organ transplant can sometimes feel like a death sentence.”

This short documentary (26 minutes) investigates the lack of Black, Asian, Minority ethnic group (BAME) organ donors and explores the influence this shortage has on the transplant black market overseas. The programme follows BBC news presenter Seb Choudhury as he donates a kidney to his mother Sakina, who had been given 3 years to live without a transplant (whereas the waiting list without his intervention might have been up to 10 years).

Circadian rhythms (In Our Time)

Review by Emma Sterling

“Circadian rhythms are a biological version of a clock inside humans and all other animals, plants and quite possibly in almost every living cell…These rhythms are a response to the most predictable condition of life on earth, that is, dark at night and bright during the day.”

“Circadian rhythms are one of the best examples of how genes relate to behaviour.”

In this episode of his series In Our Time (41 minutes), Melvyn Bragg talks with Professors Russell Foster, Debra Skene and Steve Jones about circadian rhythms, what they are and how they affect behaviour in humans and other organisms.

The programme includes a brief explanation about the subcellular process involved in circadian rhythms. In humans this takes place in what is described as the ‘master pacemaker’, formally known as the suprachiasmatic nuclei (SCN). This is a group of 50,000 cells located in the hypothalamus that are essential for producing the rhythm. Approximately 12-14 genes and their protein products are involved in the molecular feedback loop with an oscillation of approximately 24 hrs. In some individuals these oscillations are slightly longer, in others slightly less. These differences can affect whether that person is a morning or evening person. Other factors that can affect these oscillations include polymorphisms in the genes that control this process, and external factors such as food, drink and caffeine but none of the aforementioned are as important as light.

Review by Emma Sterling

Bacteria resistant to the “last resort” antibiotic colistin have been found in the UK. Public Health England says the threat to human health is low. Clive Myrie speaks to health correspondent James Gallagher in this 2 minute clip.

The colistin-resistant bacteria were first reported on a farm in China in November 2015 and have since been found in Africa and other parts of Europe. Chinese researchers have found the mcr-1 ­gene that is responsible for this resistance.

Gallagher stresses that this does not mean these bacteria are unbeatable or that a bacterial apocalypse is nigh (we hope his “Eat your Christmas dinner and don’t worry” does not become the antibacterial version of Michael Fish’s famous promise that a hurricane was not on the way). Those that are resistant to colistin are currently susceptible to other antibiotics, but the discovery raises the spectre of an entirely resistant infection. If this was to occur then routine surgery and cancer therapies might be rendered unsafe.

COPD & smoking (Sunrise)

COPD is linked to smoking

Review by Ella Yabsley

The 2.5 minute clip from Sky News breakfast programme Sunrise is a good scene-setter, providing examples of how chronic obstructive pulmonary disease (COPD) affects the physical stamina of individuals. Broadcast at the end of December, it is timed to influence people considering giving up smoking as a new year’s resolution. The clip includes coverage of Olympic athlete Iwan Thomas climbing the stairs whilst wearing a restrictive mask that mimics the effects of COPD.

Each year, around 25,000 people in the UK die from COPD. COPD is an umbrella term for emphysema, chronic bronchitis and other chronic obstructive airways diseases that affect the respiratory system (principally, the lungs). The report highlights smoking as a major risk factor for COPD development; increases in smoking directly correlates with more severe COPD symptoms. In addition to 25,000 people per annum dying from COPD, it is estimated that a further 3 million people in the UK are living with the condition.

“To start with it’s often just a smoker’s cough with some phlegm at the back of the throat. People write it off and say “oh, that’s normal”; but it inexorably goes downhill so that they get so bad that they’re short of breath all the time” – Dame Sally Davies, Chief Medical Officer for England
