Abstract Article 1

Voici une proposition d’abstract structuré pour l’article : Bawden, Stephen, et al. “Increased liver fat and glycogen stores after consumption of high versus low glycaemic index food: A randomized crossover study.” Diabetes, Obesity and Metabolism 19.1 (2017): 70-77.

CONTEXTE

L’indice glycémique des aliments consommés influence potentiellement le stockage de glycogène et la graisse hépatique.  L’objectif de l’étude était de mesurer ces effets immédiatement après la consommation des aliments et à plus long terme

METHODES

Huit volontaires masculins ont subi des examens avant et après avoir suivi pendant 7 jours un régime à indice glycémique élevé IGE ou bas IGB et dont les contenus en macronutrients et calories étaient identiques.  Après une période de quatre semaines minimum sans suivre de régime, les participants ont refait la même chose mais en suivant l’autre régime.  Pendant la semaine de régime les niveaux de graisse hépatique (1 H spectroscopie à résonance magnétique (SRM)), de glycogène (13 C SRM) et le volume de contenu gastrique (IRM) ont été mesurés.  Les niveaux de glucose et d’insuline ont été évaluées à intervalles régulières dans la journée par prises de sang.

RESULTATS

Les niveaux de glucose et d’insuline maximaux, ainsi que la zone située sous la courbe étaient nettement plus élevés après un repas IGE, comme prévu (p < .05) et encore plus élevés après 7 jours de régime IGE par rapport au début de l’intervention.  La fraction lipidique hépatique a augmenté de façon significative après l’intervention IGE par rapport à l’intervention IGB (analyse de variance à deux facteurs à mesures répétées)

CONCLUSION

Par rapport au régime IGB, un régime IGE de 7 jours a augmenté le stockage de graisses et de glycogène.  Cette observation pourrait être pertinente dans la prévention et traitement de la stéatose hépatique non alcoolique.

AIM:

To investigate the acute and longer-term effects of low (LGI) versus high glycaemic index (HGI) diets on hepatic fat and glycogen accumulation and related blood measures in healthy volunteers.

METHODS:

Eight healthy men (age 20.1 ± 0.4 years, body mass index 23.0 ± 0.9 kg/m2 ) attended a test day before and after a 7-day macronutrient- and energy-matched HGI or LGI diet, followed by a minimum 4-week wash-out period, and then returned to repeat the intervention with the alternative diet. During test days, participants consumed either an HGI or an LGI test meal corresponding to their diet week, and liver fat [ 1 H magnetic resonance spectroscopy (MRS)], glycogen ( 13 C MRS) and gastric content volume (MRI) were measured. Blood samples were obtained regularly throughout the test day to assess plasma glucose and insulin levels.

RESULTS:

Plasma glucose and insulin peak values and area under the curve were significantly greater after the HGI test meal compared with the LGI test meal, as expected. Hepatic glycogen concentrations increased more after the HGI test meal ( P < .05) and peak levels were significantly greater after 7 days of HGI dietary intervention compared with those at the beginning of the intervention ( P < .05). Liver fat fractions increased significantly after the HGI dietary intervention compared with the LGI dietary intervention (two-way repeated-measures analysis of variance P ≤ .05).

CONCLUSIONS:

Compared with an LGI diet, a 1-week HGI diet increased hepatic fat and glycogen stores. This may have important clinical relevance for dietary interventions in the prevention and management of non-alcoholic fatty liver disease.

L2 – Traduction 3

Energy drinks could weaken the heart

Energy drinks have been around for a few decades, but have really taken off in recent years.  As their name suggests they give a boost of energy, usually due to several psychoactive substances they contain which improve attention and concentration and reduce the feeling of tiredness.  They are not the same thing as sports energy drinks which contain nutritional substances vital for sports performance.

For a while now, public health authorities have been concerned about the effects of excessive consumption of some of the substances in energy drinks, including caffeine and taurine which, in high doses, might lead to heart problems or anxiety.

One by one, institutions are condemning the dangers of excessive consumption of this sort of drink, in particular when they are consumed with alcohol.  Now a team from Friedrich Wilhelm University in Bonn have presented their work at the annual congress of the Radiological Society of North America (RSNA) in which they demonstrate the effects of a single drink on the heart.

Lower contractile function after one energy drink

“Several epidemiological studies have demonstrated a link between the consumption of energy drinks and heart problems,” said Jonas Dörner, director of the study.  “But none has shown the effects they have on heart function.”  So he and his team undertook this job.  Thanks to MRI the scientists were able to observe cardiac function in 15 healthy participants aged 27 ½ on average.  They took images of the heart before and one hour after absorption of an energy drink containing 400mg/100ml of taurine, and 32mg/100ml of caffeine.

When they looked at the images of the heart, the study’s authors observed increased cardiac tension in the left ventricle after consumption of the energy drink.  This part of the heart receives oxygenated blood from the lungs and sends it into the aorta which then distributes it to the rest of the body.  However, the researchers did not note any difference in heart rate, blood pressure, nor in the rate of blood pumped by the left ventricle.  In contrast, the heart showed lower contractile function after consumption of the beverage.

“Additional studies are now needed to understand the mechanism and to determine how long it lasts,” the researcher said.  “We also want to evaluate the effect of regular consumption of these energy drinks on heart function.” For the present, the study’s authors recommend that children and the frail abstain from consuming such products.

Diabetes and endocrine disruptors: beware of chemical pollutants

Many studies have pointed to the role that some chemical products, like bisphenol A (BPA), dioxins and phthalates, play in the rapid increase in the number of people with diabetes.

It all began with diethylstilbestrol, a drug given to pregnant women up until the middle of the seventies, which caused malformations and cancer in some children.  Less well-known is the fact that people exposed in their mothers’ wombs also developed diabetes as adults twice more than average.

Since the worldwide type 2 diabetes epidemic seems difficult to explain by genetics, which have not evolved quickly enough, or by changes in lifestyle (physical inactivity, unbalanced diet) it raised suspicion.  To find out more, researchers carried out laboratory experiments.

They observed that by when they gave very small doses of diethylstilbestrol or BPA of pregnant rats or mice, their offspring became obese then diabetic.  The same thing happened with pesticides like DDT, dioxins or some phthalates, the molecules which are found in plastics.  What these products have in common is that they affect the way hormones work (which is why they are called endocrine disruptors), but they also interfere with the metabolism of carbohydrates and fats.

As far as humans are concerned, other studies have increased our suspicions.  First of all there are the consequences of accidental exposure, such as the explosion of a factory in Seveso in Italy in 1976 which produced a giant cloud of dioxins: girls who were contaminated had diabetes three times more frequently than the rest of the population when they were adults.

But the most tangible results come from longitudinal studies from the USA, Canada or Scandinavia, where those most exposed to endocrine disruptors in the past were also those who had most often ended up with metabolic disorders and diabetes.

Beware of these chemical pollutants.  It cannot be denied that they have “obesogenic” or “diabetogenic” properties.  Discussions are being held at European level to limit their use and people’s exposure to them.

Meanwhile, pregnant women at least should take precautions: avoid tins and cans, which are all lined with BPA, as are containers and plastic films in microwave ovens, choose organic food whenever possible, don’t repaint the nursery, and avoid handling pesticides during pregnancy.
