Energy Expenditure (Calories Burned) in Anorexia Nervosa Patients

by Tetyana in Science of Eating Disorders


How many calories do patients with anorexia nervosa need to eat to gain a kilo (2.2 lbs)? It seems like a simple question and one that we should have figured out a long time ago, given the importance (err, necessity) of refeeding and weight restoration in recovery from anorexia nervosa.
Unfortunately, research in this area has often led to contradictory results (see Salisbury et al., 1995 and de Zwaan et al., 2002 for reviews). Fortunately, a paper by Stephan Zipfel and colleagues (2013,........ Read more »

Cannabis use and structural changes in the brain

by Robb Hollis in Antisense Science

“One or two spliffs a week could mess up your brain” – Metro, 16 April 2014

Spark your interest? This headline caught the eyes of the Antisense team, so we chased down the original article in the Journal of Neuroscience and took a closer look!

Cannabis is the most commonly used illegal drug in the US, and the ‘casual use’ culture surrounding marijuana is a subject of great debate and controversy, with arguments for drug legalisation making their way into our ........ Read more »

Mitochondrial dysfunction as a neurobiological subtype of autism

by Paul Whiteley in Questioning Answers

The paper by Suzanne Goh and colleagues [1] reporting on "a possible neurobiological subtype of mitochondrial dysfunction in ASD [autism spectrum disorder]" is a worthy addition to the research roll call which has graced this blog down the years. Based on the analysis of brain lactate levels - a potential marker of mitochondrial dysfunction - via the analysis of lactate doublets on brain magnetic resonance spectroscopic imaging (MRSI), authors picked up a significantly higher rate of l........

Glucosidase I: Could targeting N-linked glycosylation of proteins help us fight viral infection?

by Amy Swanston in Antisense Science

Viruses are sneaky. As you probably already know from your last bout with the common cold or the flu, for most viral infections doctors will simply prescribe plenty of water and bed rest. But what if we could stop the virus from replicating, or block it from entering the host cells in the first place?
Recent research on two siblings with a rare mutation in a key glycosylation enzyme (alpha-glucosidase I) sparked our interest as these children were found to be resistant to a number of bacteria........ Read more »

Using Pain To Stop Pain

by Mark Lasbury in As Many Exceptions As Rules

Chronic pain can involve TRPV1 pathways, yet traditional TRPV1 antagonists cannot be used due to incidence of hyperthermia. New research has identified new routes of administration, new agonists and new allosteric functions that will make TRPV1 a viable target for chronic, acute, and cancer-mediated pains. Alternative mechanisms, such as counter irritants and acupuncture are also gaining in evidence for mechaisms that involve TRPV1 signaling pathways... Read more »

Joined by HDAC (inhibitors)

by Paul Whiteley in Questioning Answers

I'm treading quite carefully with this post which came about following my [non-expert] reading of the paper abstract from Anand Venkatraman and colleagues [1] on a potential downside to the use of HDAC (histone deacetylase) inhibitors for treating spinocerebellar ataxia type 1 (SCA1), a progressive disease affecting movement and other knock-on functions. This follows other work suggesting that certain HDAC inhibitors might offer some important new lines of investigation when it co........ Read more »

New Study Shows Surgical Checklists In Operating Rooms Are Less Effective Than Assumed

by Jalees Rehman in The Next Regeneration

Optimizing such tailored checklists, understanding why some studies indicate benefits of checklists whereas others do not and re-evaluating the efficacy of checklists in the non-academic setting will all require a substantial amount of future research before one can draw definitive conclusions about the efficacy of checklists. Regulatory agencies in Canada and the United Kingdom should reconsider their current mandates. Perhaps an even more important lesson to be learned is that health regulator........ Read more »

Religious Belief and Depression Resilience

by William Yates, M.D. in Brain Posts

Identifying risk factors for brain disorders is a key element in clinical research.Understanding protective or resilience factors for brain disorders is also important and receiving increased attention in clinical research.Factors that promote resilience to brain disorders may come from a variety of domains. Religious belief is one domain receiving attention as a potential resilience factor.Miller and colleagues recently published a longitudinal study of religious belief and risk for major ........

Disordered Eating and Athletic Performance: Where’s the Line?

by Emma in Science of Eating Disorders


If a person severely restricts his diet and exercises for hours each day, he has an eating disorder. If another does exactly the same but it is because she wants to make the lightweight rowing team (which has an upper weight limit), she’s a committed athlete. When the two overlap, and an athlete presents with eating disorder symptoms, how do we distinguish between the demands of the sport and the illness?
I’ve been interested in the distinctions we make between disordered and n........ Read more »

Does Access to Birth Control Reduce Poverty?

by Eric Horowitz in peer-reviewed by my neurons

In American politics the proliferation of birth control is important because of how it affects the eternal resting place of our immortal souls. But believe it or not, there are also non-metaphysical policy consequences to increasing access to birth control. A new study by a pair of economists — Stephanie Browne of J.P. Morgan and […]...

Neurology of inflammatory bowel diseases

by Paul Whiteley in Questioning Answers

The paper by Ben-Or and colleagues [1] talking about a neurologic profile present in a small participant cohort of children and adolescents diagnosed with an inflammatory bowel disease (IBD) caught my eye recently. Their findings reporting that over two-thirds of their paediatric participant group diagnosed with IBD also "exhibited neurologic manifestations" provides some compelling preliminary evidence for further investigation in this area.Outside of reports of headache and dizziness, the pres........

The Curse of the Internet

by Aurametrix team in Health Technologies

It's hard to imagine our lives without the Internet  - either mobile or desktop. The Internet has become a catalyst of innovation, an essential tool in business and social life. It brought new levels of participation and access to knowledge. It enabled new forms of interaction, albeit mostly utilized for entertainment purposes. But despite all the advantages and conveniences, does the Internet really serve us or is it the other way around?... Read more »

Dad's obesity and risk of offspring autism

by Paul Whiteley in Questioning Answers

In this post I'm talking about the paper by Pål Surén and colleagues [1] and their suggestion that "paternal obesity is an independent risk factor for ASDs [autism spectrum disorders] in children". I do so not with the intent of stigmatising parents and specifically parents with weight issues, which tend to be present for many more reasons than just food and exercise (see here), but merely to highlight how parental physical health may show some relationship to offspring cog........

Aluminum adjuvants in vaccines: are they safe?

by EE Giorgi in CHIMERAS

Multnomah Falls, © EEGDisclaimer: I work on HIV vaccine design and I'm quite proud of it. I know that for three million HIV-positive kids in Africa, a vaccine is the only hope they have to grow into adulthood. So, when people tell me that vaccines are bad I cringe. Infant mortality rates have dropped since vaccinations have been introduced. We live longer, healthier lives thanks to vaccines. Diseases like polio can paralyze and kill, yet they are no longer a concern for children in the western ........ Read more »

Gluten exposure and "feelings of depression"?

by Paul Whiteley in Questioning Answers

Could exposure to dietary gluten affect a person's moods or emotional state?Well, if the paper by Simone Peters and colleagues [1] (open-access here) is to be believed the answer may very well be yes, at least in some cases, as they report a link between gluten consumption and feelings of depression under [short-term] experimental conditions. If replicated, such a finding may have profound consequences for how we view our relationship between food and mental health and wellbeing.Bread Ma'am?&nbs........ Read more »
