9hour eating window

9-Hour eating window may protect brain health

A new early study suggests that limiting all meals and snacks to a 9-hour eating window each day and avoiding food for at least four hours before bedtime may help reduce the risk of memory and thinking problems in older age.

The study looked at older women who were overweight or obese.

Researchers found that women who ate within the set time window showed better mental performance than those who spread their meals over a longer period during the day.

Experts say this was a small pilot study so more research is needed to confirm the findings.  However if future studies show similar results time restricted eating could become a simple way to support brain health as people age.

Professor Sue Shapses a nutrition expert at Rutgers University in the United States said that weight loss alone may help slow age related decline in brain function.

She added that eating only within an 8- to 9-hour period and stopping food intake at least four hours before sleep may provide extra benefits.

Dementia is one of the leading causes of death worldwide with around 2 million people dying from the disease each year.

While age and genetics cannot be changed experts say that a healthy lifestyle could help prevent or delay nearly half of dementia cases.

They also note that obesity in middle age may increase the risk of developing dementia later in life by about 30%.

  • Vaping risks for young people

    A major review by the Royal College of Paediatrics and Child Health has raised concerns about the growing use of e-cigarettes among children and teenagers. Researchers reviewed thousands of studies looking at how vaping may affect the health of young people. Vaping has increased sharply According to the report vaping among young people has increased 10 times over the past decade.  Many teenagers are also starting to vape at a very young age, increasing concerns about long term health effects. Vaping may harm lung health The review linked vaping among young people with several breathing problems including: •Coughing •Wheezing •Symptoms of bronchitis Worsening asthma symptoms Experts also warn that young people who vape may be more likely to start smoking traditional cigarettes later. Other possible health effects The report also highlighted several other concerns linked to vaping including. Nicotine addiction •Poor oral and dental health •Anxiety •Depression •Suicidal thoughts •Possible sleep problems •Potential effects on eye health •Allergies Researchers say more studies are still needed to fully understand some of these effects. Experts warn parents and young people Professor Will Carroll a co-author of the report said vaping should not be viewed as a harmless part of growing up. The evidence shows clear links between vaping, breathing problems nicotine dependence and future cigarette use. Vaping may look less harmful than traditional smoking but experts warn that it can still pose serious risks for children and teenagers. Preventing young people from starting vaping could help protect their health both now and in the future.

  • Lower protein may boost longevity

    Protein rich foods such as cereals coffee water and many other products have become increasingly popular. However a new study suggests that for many people eating less protein instead of more may actually be better for overall health and could even help people live longer. The review published on July 31 in the journal Cell Press Blue examined more than 350 scientific studies exploring the connection between lower protein intake and healthy aging. Researchers found that reducing protein intake may improve metabolism help cells respond better to nutrients lower cell damage and support normal cell function. Together these effects may promote better health and a longer lifespan. The study’s lead author Dudley Lamming said that protein is important for people who exercise regularly because it helps build muscle and improves workout results. However he added that most people are not very physically active which means they may be eating more protein than their bodies actually need. In some cases this could have negative effects on health. Experts also noted that the right amount of protein is different for everyone.  It depends on factors such as age overall health physical activity and lifestyle. They recommend following a balanced diet and getting advice from a healthcare professional before making major changes to protein intake.

  • HEC new weighted policy: putting weight on research credibility

    By Ali Abbas Pakistan’s Higher Education Commission (HEC) new weighted research policy has surely raised an eyebrow among a few academics nationwide. Before further dissecting the policy and its implications, it is pertinent to understand the role of HEC as a regulatory authority, which can help clear the air to a greater extent. As stated, “Regulatory”, it is important to accept that the Higher Education Commission of Pakistan is there to implement quality checks irrespective of the decision being popular or unpopular. So, with this lens, it is easy to understand why HEC is weighing this bold step of assigning weights to authorship and what must have been the shortcomings in the previous policy, despite the earlier policy’s apparent benefits. The new policy values first authors and corresponding authors more, acknowledging a reward for the initiators and potential stakeholders in the event that there are more than 3 authors. While HEC is not stopping co-authorship, it aims to credit researchers who have genuine contributions and are adding value as a lead or major contributor. It is entirely up to contributors to choose the number of other co-authors and their desired contribution and commitment in the research article. In fact, this should rather be seen as a measure of transparency that researchers who are expecting to get fewer marks for co-authorship will be doing less work in contrast to the first author. That can actually act as a yardstick for them to allocate their time to multiple projects to get their respective share/ count. However, not to undermine the researchers whose genuine intent surrounds a higher number of publications in less time with real contribution, it is a welcoming sign for authors who stay away from relationship-based and aided research. So, HEC, being a quality custodian of education and research practices for HEIs, has come up with a stance to curb research mills, fraudulent research, and fake authorship, where publications in friends’ journals and contributions following quid pro quo are compensated. And one never knows when these researchers who have worked as co-authors or fall last in the author list make it to the classes; their share of knowledge and impact may be a concern at times as well. The problem is even bigger, as not only papers with 20+ authors can be found, but researchers are co-authoring in different fields that may be beyond cross-domain collaboration. This is where HEC might have to respond and find this weighted policy as damage control.  Well, this research’s credibility is not Pakistan’s dilemma only, but something that is a world issue in a higher education setting. And when HEC addresses these concerns, it might act as a benchmark for other nations’ education systems, especially for the education and accreditation councils of similar demographics. Whether one favors or opposes it, HEC has devised something that raises major concerns, and that is to curb the need to distinguish between real and fake contributors. Now comes the point of demotivating international contributions from this weighted system, as raised by the affected prospective contributors. Well, though not every policy can avoid its collateral, the overall gain may be exploited as well. It is to be remembered that international collaborators are not to be linked with those weights; they can continue to collaborate at any number in the author list as they used to be, i.e., first or second or third, etc. In this case, the logic for local authors will remain the same as stated above about their respective contributions and rewards. The time and effort can then help in identifying multiple avenues as well. Again, there are always two sides to a coin, and in the current dynamics, where co-authorship has appeared to be a business deal, the side with the assigned weights policy bears more weight. Also, on the other hand, the offset can be made by allocating funds and instructing HEIs to devote funding to Gold open access, thus accelerating the pace of the first-author research. All in all, the new policy hints at increasing competitiveness and research credibility while leaving it to the test of time to see if it turns out to be a value addition for researchers by choice or by chance.

  • Early sugar control benefits brain health

    A new study suggests that giving children little or no sugar before the age of two may help reduce their risk of developing dementia later in life. Researchers found that people who were exposed to very low amounts of sugar during pregnancy and in their first two years of life had a 23% lower risk of dementia as adults. Health experts say eating too much sugar is already linked to type 2 diabetes which can damage blood vessels and increase the risk of dementia. The new findings suggest that limiting sugar early in life may also support long term brain health. The study’s lead author, Dr. Jiaxin Zheng said the results show that reducing sugar intake during early childhood could have lasting benefits for brain health. Researchers added that while the findings are encouraging more studies are needed to confirm the connection between low sugar intake in early life and a lower risk of dementia.

  • Chickenpox cases rise in Gaza

    The United Nations has warned that chickenpox cases are increasing among displaced children in Gaza. Around 9,300 cases have been reported over the past two weeks with more than half recorded in Khan Younis. According to the UN Office for the Coordination of Humanitarian Affairs (OCHA) overcrowded displacement camps piles of garbage limited access to clean water and damaged sewage systems are creating ideal conditions for infectious diseases to spread. As a result chickenpox is becoming a serious public health concern. The UN said respiratory illnesses and skin diseases remain the most common health problems in Gaza. Waterborne diseases are also increasing especially in the Khan Younis area due to poor sanitation and contaminated water. Last week alone more than 18,000 new cases of skin-related illnesses including chickenpox external parasitic skin infections and impetigo were reported. The report also said Gaza’s healthcare system has been badly damaged by the ongoing war. Many hospitals and medical facilities have been destroyed or damaged while shortages of medicines fuel and medical supplies continue to affect healthcare services. According to the Palestinian Ministry of Health, since the war began more than 73,250 Palestinians have been killed and 173,751 injured. The ministry also said that around 90% of Gaza’s infrastructure has been damaged or completely destroyed.

  • Unemployment

    Through the columns of your newspaper, I want to draw the attention of the concerned authorities towards the growing problem of unemployment in our country. Unemployment is a serious problem, especially among educated young people. Many students complete their education but cannot find suitable jobs. Due to unemployment, people face poverty, frustration, and many social problems. It also slows down the progress of the country. The government should create more job opportunities and encourage industries and small businesses. Technical and vocational education should also be promoted so that young people can learn useful skills and earn a living. I hope the concerned authorities will take immediate steps to control unemployment and provide better opportunities for our youth.
