‘70% north Indian women low in vitamin D, at high diabetes risk’

An inverse relationship exists between vitamin D levels and blood sugar levels indicating lower the vitamin D levels, the higher the blood sugar.

VITAMIN D

New Delhi, July 4: Despite adequate exposure to sunshine, nearly 70 per cent pre-diabetic women in north India are “deficient” in vitamin D, making them more vulnerable to the risk of developing Type-2 diabetes, finds a study.

Pre-diabetes is a condition in which blood sugar is high, but not high enough to be type 2 diabetes.

The findings showed that pre-diabetes women living in north India were 68.6 per cent vitamin D “deficient”, 26 per cent have “insufficient” levels, while only 5.5 per cent have “sufficient” levels of the vitamin.

“In India, there is a need to understand this as women have a propensity to be obese, develop metabolic syndrome, consequent hyperglycaemia and thereby be at the risk of diabetes. The pace at which women are moving from the pre-diabetic stage to the diabetic stage is alarming,” Anoop Misra, Chairman Fortis C-Doc, said in a statement.

“If this could be prevented by prescribing a cost effective vitamin D supplement, it would be truly amazing,” he added.

According to the researchers, an inverse relationship exists between vitamin D levels and blood sugar levels indicating lower the vitamin D levels, the higher the blood sugar.

It is because vitamin D may have a direct effect on the pancreatic beta cell function, thereby increasing insulin production.

“Previous studies had already established the link between the high prevalence of vitamin D deficiency and abdominal obesity. However, the relationship between vitamin D and the development of pre-diabetes, with a special focus on women, has remained obscure and unexplored,” Misra noted.

According to a recent report by India Spend, the country currently represents 49 per cent of the world’s diabetes burden, with an estimated 72 million cases in 2017, a figure expected to almost double to 134 million by 2025.

For the study, published in the British Medical Journal, the team included 797 women between the ages of 20 and 60.

The results indicated that women from lower socio-economic groups tend to have a higher vitamin deficiency that those from higher socio-economic groups.

Post-menopausal women who suffer from low calcium deposits in addition to low vitamin D deficiency were also found to be at a higher risk of bone damage than others.

Supplementation with vitamin D — present in foods such as milk, eggs, salmon, tuna, and mushroom — may prevent diabetes in India women, the researchers suggested.

A healthy diet, regular physical activity, maintaining a normal body weight and avoiding tobacco use are ways to prevent or delay the onset of Type-2 diabetes, the researchers 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.
