Back pain: This is what anti-inflammatory drugs can do to your body

February 6, 2017

New Delhi, Feb 6: A new study reveals that taking non-steroidal anti-inflammatory drugs, such as Ibuprofen, may provide little benefit than a placebo when it comes to treating back pain.

Backpain The study found that patients taking anti-inflammatory drugs were 2.5 times more likely to suffer from gastro-intestinal problems such as stomach ulcers and bleeding.

The research, published in the Annals of the Rheumatic Diseases, doesn't mean NSAIDs don't work at all for back pain and shouldn't be used.

It revealed that only one in six patients treated with the pills achieve any significant reduction in pain, suggesting that it's possible that some people may still benefit from using them.

Lead author Manuela Ferreira from the University of Sydney said the study highlights an urgent need to develop new therapies to treat back pain which affects 80 percent of Australians during their lifetime.

"Back pain is the leading cause of disability worldwide and is commonly managed by prescribing medicines such as anti-inflammatories. But our results show anti-inflammatory drugs actually only provide very limited short-term pain relief. They do reduce the level of pain, but only very slightly and arguably not of any clinical significance," Ferreira added.

For the study, the team examined 35 trials involving more than 6000 people.

"Millions of Australians are taking drugs that not only do not work very well, but are also causing harm. We need treatments that will actually provide substantial relief of these people's symptoms," said co-researcher Gustavo Machado.

"Better still, we need a stronger focus on preventing back pain in the first place. We know that education and exercise programs can substantially reduce the risk of developing low back pain," Machado explained.

The study is the latest work from The George Institute questioning the effectiveness of existing medicines for treating back pain.

Back pain can range from a dull, constant ache to a sudden, sharp pain that makes it difficult to move. Although back pain usually gets better by itself after a few weeks, it might be a good idea to seek medical help.

Maintaining a healthy weight is important for overall health and can help you prevent and control many conditions, including back pain.

'Children under the age of 5 carry higher levels of Covid-19'

Washington, Aug 2: Children under the age of five have between 10 to 100 times greater levels of genetic material of the coronavirus in their noses compared to older children and adults, a study in JAMA Pediatrics said Thursday.

Its authors wrote this meant that young children might be important drivers of Covid-19 transmission within communities -- a suggestion at odds with the current prevailing narrative.

The paper comes as the administration of US President Donald Trump is pushing hard for schools and daycare to reopen in order to kickstart the economy.

Between March 23 and April 27, researchers carried out nasal swab tests on 145 Chicago patients with mild to moderate illness within one week of symptom onset.

The patients were divided into three groups: 46 children younger than five-years-old, 51 children aged five to 17 years, and 48 adults aged 18 to 65 years.

The team, led by Dr Taylor Heald-Sargent of the Ann & Robert H. Lurie Children's Hospital, observed, "a 10-fold to 100-fold greater amount of SARS-CoV-2 in the upper respiratory tract of young children."

The authors added that a recent lab study had demonstrated that the more viral genetic material was present, the more infectious virus could be grown.

It has also previously been shown that children with high viral loads of the respiratory syncytial virus (RSV) are more likely to spread the disease.

"Thus, young children can potentially be important drivers of SARS-CoV-2 spread in the general population," the authors wrote.

"Behavioral habits of young children and close quarters in school and daycare settings raise concern for SARS-CoV-2 amplification in this population as public health restrictions are eased," they concluded.

The new findings are at odds with the current view among health authorities that young children -- who, it has been well established, are far less likely to fall seriously ill from the virus -- don't spread it much to others either.

However, there has been fairly little research on the topic so far.

One recent study in South Korea found children aged 10 to 19 transmitted Covid-19 within households as much as adults, but children under nine transmitted the virus at lower rates.

Study links children's mental health to sleep duration

Agencies

February 10,2020

Washington D.C, Feb 10: Children's vulnerability towards depression, anxiety, impulsive behaviour, and poor cognitive performance could be determined by considering the hours of sleep they manage to get.

Sleep states are active processes that support the reorganisation of brain circuitry. This makes sleep especially important for children, whose brains are developing and reorganising rapidly.

In a study by researchers from the University of Warwick -- recently published in the journal Molecular Psychiatry -- cases of 11,000 children aged between 9 and 11 years from the Adolescent Brain Cognitive Development dataset were analyzed to find out the relationship between sleep duration and brain structure.

The study was carried out by researchers Professor Jianfeng Feng, Professor Edmund Rolls, Dr. Wei Cheng and colleagues from the University of Warwick's Department of Computer Science and Fudan University.

Measures of depression, anxiety, impulsive behaviour and poor cognitive performance in the children were associated with shorter sleep duration. Moreover, the depressive problems were associated with short sleep duration one year later.

The reduced brain volume of areas such as orbitofrontal cortex, prefrontal, and temporal cortex, precuneus, and supramarginal gyrus was found to be associated with the shorter sleep duration.

Professor Jianfeng Feng, from the University of Warwick's Department of Computer Science, comments: "The recommended amount of sleep for children 6 to 12 years of age is 9-12 hours. However, sleep disturbances are common among children and adolescents around the world due to the increasing demand on their time from school, increased screen time use, and sports and social activities."

A previous study showed that about 60 per cent of adolescents in the United States receive less than eight hours of sleep on school nights.

Professor Jianfeng Feng further added: "Our findings showed that the total score for behavior problems in children with less than 7 hours sleep was 53 per cent higher on average and the cognitive total score was 7.8 per cent lower on average than for children with 9-11 hours of sleep. It highlights the importance of enough sleep in both cognition and mental health in children."

Professor Edmund Rolls from the University of Warwick's Department of Computer Science also commented: "These are important associations that have been identified between sleep duration in children, brain structure, and cognitive and mental health measures, but further research is needed to discover the underlying reasons for these relationships."
