Stressed newborns feel more pain, but don’t cry: Study

Published

on

London, Dec 4 : When newborn babies are under stress, their brains show a heightened response to pain, but the baby is unlikely to show it by crying, a new study has found.

The findings showed that stress leads to an apparent disconnect between the baby’s brain activity and his/her behaviour.

Stressed babies might appear not to respond to pain, as their brain is still processing it. As a result, the caregivers are likely to underestimate the baby’s pain experience.

Thus, it is imperative to identify different ways to understand babies who are stressed, the researchers suggested.

“When newborn babies experience a painful procedure, there is a reasonably well coordinated increase in their brain activity and their behavioural responses, such as crying and grimacing,” said Laura Jones from the University College London.

“Babies who are stressed have a larger response in the brain following a painful procedure. But, for these babies, this greater brain activity is no longer matched by their behaviour,” Jones added.

For the study, reported in the journal Current Biology, the team enrolled healthy, newborn infant boys and girls from the postnatal ward and special care baby unit and measured the babies’ stress levels based on salivary levels of cortisol stress hormone and heartbeat patterns, both before and after a clinically necessary heel lance.

At the same time, they measured the babies’ pain response using EEG brain activity and facial expression.

The data showed that babies with higher levels of background stress showed a bigger brain reaction to the heel lance procedure. However, that heightened activity in the brain didn’t correspond to a change in the babies’ behaviour.

The study offer yet another reason to treat and care for babies in ways that minimise both pain and stress, Jones said.

Obese teenagers can face pancreatic cancer risk

Pancreatic cancer

New York, Nov 12: If your teenager or young adult child is obese, he or she can be at four-times the risk of developing pancreatic cancer later in life, new research warns.

Researchers from the Tel Aviv University analysed 1,087,358 Jewish men and 707,212 women between 16 to 19 years for the study published in the journal CANCER.

It showed that overweight and even higher weight within the “normal” weight range in men may increase pancreatic cancer risk in a graded manner.

Compared with normal weight, obesity was associated with a 3.67-times higher cancer risk among men and a 4.07-times higher risk among women, the report said.

In addition, high-normal BMI and overweight men were associated with 49 per cent and 97 per cent higher risks for cancer, respectively, as compared to those with low-normal BMI.

Pancreatic cancer is the sixth most common cause of cancer-related deaths in the world and adult obesity has been linked with an increased risk for its occurrence.

It has an extremely low survival rate which has barely improved over the last 40 years.

The combination of complex chemical, biological, bio-mechanical and structural factors found in pancreatic cancer tissues makes it difficult to treat.

Systemic inflammation caused by obesity is a potential driver behind the development of pancreatic cancer. Thus, managing weight could help reduce the risk, the researchers noted.

Salmonella resistant to different antibiotics: Study

Published

on

New York, Nov 11 : Salmonella, a common bacteria that causes foodborne diseases, are resistant to several antibiotics used to treat infections, suggests new research.

For the study, the researchers sequenced and investigated the genomes of 90 strains of a specific serological variant (serovar) of Salmonella enterica known as S. Typhimurium.

When the action of antibiotics in each of the 90 strains was tested, it was discovered that the vast majority were resistant to different classes of antibiotics that are part of the arsenal of medicine.

The study, published in the journal PLOS ONE, also identified 39 genes responsible for resistance to antibiotics.

“It is striking that S. Typhimurium is resistant to antibiotics that can be used to treat the disease. These drugs are available to physicians for use in combating infections that display resistance,” said Amanda Aparecida Seribelli from the University of Sao Paulo in Brazil.

Salmonella comprises two species, S. bongori and S. enterica. The latter is the type species, with a large number of subspecies and serovars that cause more foodborne infections than any other species in Brazil and worldwide.

The human and animal intestinal tract is the main natural reservoir for this pathogen, with poultry, pork and related food products serving as major transmission vectors.

The six subspecies of S. enterica are subdivided into 2,600 serovars.

The most important subspecies of S. enterica from the epidemiological standpoint is S. enterica subspecies enterica, which causes the foodborne infection known as salmonellosis. The symptoms are diarrhoea, fever, stomach cramps and vomiting.

The most frequently isolated serovars of this subspecies are S. Typhimurium and S. Enteritidis.

All the 90 strains analysed in the study belonged to S. Typhimurium.

Whole-genome sequencing of the main bacteria that cause acute diarrohea was the focus of the research.

According to the study, 65 of the strains proved resistant to sulfonamides, 44 to streptomycin, 27 to tetracycline, 21 to gentamicin and seven to ceftriaxone, a cephalosporin antibiotic.(IANS)

Social media use linked to depression, loneliness: Study

Published

Social Media

New York, Nov 10: Excessive use of social media including Facebook, Snapchat, and Instagram is associated with poor well-being which could lead to depression and loneliness, researchers have warned.

The study, published in the Journal of Social and Clinical Psychology, showed that limiting screen time on these apps could boost one’s wellness.

“When you are not busy getting sucked into clickbait social media, you are actually spending more time on things that are more likely to make you feel better about your life,” said Melissa Hunt from the University of Pennsylvania in the US.

For the study, researchers from the varsity, included 143 undergraduate participants.

The team designed their experiment to include the three platforms most popular with the participants.

They collected objective usage data automatically tracked by iPhones for active apps, not those running in the background, and asked respondents to complete a survey to determine mood and well-being.

The participants were then randomly assigned to a control group, which had users maintain their typical social-media behaviour, or an experimental group that limited time on Facebook, Snapchat, and Instagram to 10 minutes per platform per day.

In addition, the participants shared iPhone battery screenshots for the next three weeks to give the researchers weekly tallies for each individual.

The team then looked at seven outcome measures including fear of missing out (FOMO), anxiety, depression, and loneliness.

The results showed that using less social media than you normally would lead to significant decrease in both depression and loneliness.

However, young people aged between 18 to 22 should not stop using social media altogether, suggested the findings.

“Because these tools are here to stay, it is incumbent on society to figure out how to use them in a way that limits damaging effects,” Hunt noted.
