Artificial sweeteners alter weight loss goals

No-calorie sweeteners may interfere with people’s diet choices, research has revealed.

For the study, researchers conducted three experiments in which 116 participants ages 18 to 25 were randomly given an unmarked cup filled with either a non-caloric sweetened beverage (a diet soda), a sugar sweetened beverage (regular soda) or non-sweetened beverage (sparkling water). Researchers then measured their cognition, snack choices and responses to sugary food.

Sarah Hill, associate professor of psychology at Texas Christian University (TCU), said that people just don’t seem to compensate for the calories consumed in a beverage. Even if they consciously think about it, a less deliberate part of their mind might not really register those calories.

She further added that the totality of these studies suggested that drinking artificially sweetened beverages can have unintended consequences and, over time, might influence choices that can affect weight loss goals.

YouTube no good for basic life support videos 

A study conducted by Turkish emergency medicine specialists has observed that there are very few CPR and basic life support (BLS) videos available on YouTube that provide instructions which are updated with recent health guidelines. The study reviewed the educational videos from the last three years accessed via YouTube.

Associate Professor Paul Middleton said that although well-designed videos could create awareness and be useful as tools in training, they could never replace hands-on instruction from a properly qualified health practitioner.

 A total of 209 videos were eventually analysed and only 11.5 per cent of them  were found to be completely compatible with 2010 CPR guidelines with regard to sequence of interviews. 

Physical activity helps men control nocturia

Men who exercise on a regular basis are at a lower risk of nocturia i.e. waking up at night to urinate, a new study says.

The study conducted by Loyola University Chicago Stritch School of Medicine analysed the data from a large, ongoing clinical trial called the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial (PLCO).

Nocturia is the most common and bothersome lower urinary tract symptom in men and it can be caused due to an enlarged prostate known as benign prostatic hyperplasia (BPH). 

Kate Wolin asserted that combined with other management strategies, physical activity may provide a strategy for the management of BPH-related outcomes, particularly nocturia. Wolin’s analysis included 28,404 men in the PLCO trial who had BPH outcomes before enrolling in the study (prevalent group) and 4,710 men who had newly developed BPH (incident group).

The research showed that among men in the incident group, those who were physically active one or more hours per week were 13 per cent less likely to report nocturia than men who reported no physical activity.  

‘Energy drinks’ may trigger acute heart problems 

Researchers have found that energy drinks can cause heart problems. Several people consume a number of energy drinks one after the other in dance clubs and during physical exercise or workouts. 

This can lead to a number of adverse conditions including angina, cardiac arrhythmia and even sudden death, according to the study. 

Professor Milou-Daniel Drici from France highlighted that about 96 per cent of these drinks contain caffeine, with a typical 0.25 litre can holding 2 espressos worth of caffeine, which is one of the most potent agonists of the ryanodine receptors and leads to a massive release of calcium within cardiac cells that can cause arrhythmias. 

Professor Drici added that this also has effects on the heart’s abilities to contract and to use oxygen. The study found that ‘caffeine syndrome’, which is characterised by a fast heart rate, tremor, anxiety and headache, was the most common problem.
