Woman’s ‘nasty’ skin infection most likely caused by swimming in sea after shaving legs –

A woman whose nasty skin infection was most likely picked up during a swim in the sea on Aucklands North Shore believes it is unacceptable that people cannot go swimming without fear of getting sick.

Devonport resident Vanessa Ingraham developed a staph and E coli infection on her legs about four weeks ago.

Her doctor believes she may have caught the infection from swimming at Narrowneck Beach shortly after shaving her legs.

Ingraham, who moved to New Zealand from the Bahamas seven years ago, said she didnt know about Aucklands stormwater issues until she got the infection.

Devonport resident Vanessa Ingraham, who is from the Bahamas, says it is unacceptable that people cannot go swimming at Auckland beaches without fear of getting sick.

During heavy rain, water that is contaminated with animal faeces, oil, rubbish, metals and rubber from tyres is often flushed through the stormwater network and onto beaches, a Watercare spokeswoman said.

Aucklands wastewater network is also known to overflow during heavy rain, which causes sewage to spill out from manholes, gully traps, pump stations and engineered overflow points into properties, waterways and the sea.

The Auckland Councils Swimsafe website, which provides real-time forecasts of beach water quality, recommends people avoid swimming for 48 hours following heavy rainfall.

You have to check to see if its safe to swim? This is a foreign concept, Ingraham said.

Vanessa Ingrahams doctor believes she contracted a staph and E coli infection after swimming at Narrowneck Beach not long after she shaved her legs.

Ingraham, a wellness consultant, swims in the sea daily even in winter to reap the health benefits of swimming in cold water.

According to a 2020 study published in the International Journal of Environmental Research and Public Health, regular cold-water swimming may reduce inflammation and symptoms of depression, increase metabolism and improve resilience to stress.

All the things in our life are quite stressful, but we can deal better with mental stress when subjecting ourselves to physical distress, Ingraham said.

She believed it was unacceptable that the water network issue was causing damage to the environment.

Vanessa Ingraham, who swims in the sea daily, was not aware of the recommendation to check for health risks on Safeswim prior to getting her skin infection.

We can never be healthy in an environment thats making us sick.

Auckland Regional Public Health Service (ARPHS) public health medicine specialist Dr David Sinclair told Stuff that staph and E coli infections were common and could originate from a range of sources.

Because of this, its difficult to identify the source of a particular persons illness and, more generally, how many people may have become ill after swimming at Auckland beaches.

It is expected that 2 per cent of people who swim at a beach marked on Safeswim with a red flag, indicating high risk of illness from swimming, will get sick, with either skin, ear or respiratory infections or with diarrhoea and vomiting.


More than 50 Auckland beaches were marked on Swimsafe as unsafe for swimming following heavy rain in January.

Sinclair added that ARPHS was not aware of any deaths linked to beach water quality.

Watercare was not aware of any wastewater overflows at Narrowneck Beach in the past year, the spokeswoman said.

Work is under way to reduce wet-weather overflows, with $349.5 million spent on the wastewater network in the past year.

Over the next 20 years, we will be spending close to $11 billion on our wastewater system to reduce wet-weather overflows, improve the quality of beaches and waterways, improve wastewater treatment processes and cater for Aucklands growth.

People are asked to check that their stormwater downpipes are not incorrectly connected to the drain used for their wastewater (kitchen, laundry and toilet).

Anyone who falls ill with symptoms of respiratory, gastroenteritis, ear, eye or skin infections within three days of swimming may have a waterborne illness and is advised to visit their doctor or phone Healthline on 0800 611 116.

Over 50s Spending Spree Boosts Economy By Billions – Money International

Older consumers are a benefit to the economy rather than a drain on resources, according to new research.

The over 50s will spend 63p in every 1 in the UK by 2040 rising from 54p in the 1 in 2018.

And the money is spent across the board rather than on specific goods and services,

However, think-tank the International Longevity Centre (ILC) believes the country could benefit even more if the government looked at lifting barriers to spending by older people.

The ILC reportMaximising the longevity dividendreveals spending by the over 50s has dominated the UK economy since 2013 and will rise over the coming decades, from 54% (319 billion) of total consumer spending in 2018 to 63% by 2040 (550 billion).

According to the report, lifting barriers to spending by the over 75s could add 2% (47 billion) to GDP a year by 2040 and supporting the over 50s to remain in the workforce could add an another 1.3% to GDP a year by 2040.

David Sinclair, Director of the ILC, said: As the population ages there are enormous economic opportunities, but these are currently being neglected.

There are enormous gains to be made by individual businesses and for the economy if we can unlock the spending and earning power of older adults.

But too many people face barriers to working and spending in later life issues like inaccessible high streets, poorly designed products, and age discriminatory attitudes require a serious response.

Weve become accustomed to hearing our ageing population talked about as a bad thing but the reality is it could be an opportunity.

However, we wont realise this longevity dividend through blind optimism about ageing. Instead, we need concerted action to tackle the barriers to spending and working in later life.

We need action to make sure our extra years are healthy years, we need accessible high streets and workplaces that are free from age discrimination and we need continued action to ensure that people have access to decent pensions in later life.

Realising the longevity dividend will require decisive action of the kind weve yet to see from either business or government. For all the talk of baby boomers dominating politics, weve yet to see a serious response to the opportunities and this needs to change.

Get younger reverse ageing and increase your health span – Have a Go News

In The Curious Case of Benjamin Button, a boy was born old and got younger. That film is science fiction but Australian scientist Professor David Sinclair, currently at Harvard University Medical School and his colleagues have managed to get yeast and more recently mice to grow younger.

Aging has multiple causes, until recently none have been considered treatable. It is the diseases of old age: dementia, heart disease and osteoporosis that have been treated.

No matter how much you exercise, fitness trackers can be a great way to help you stay -- or get -- in shape without the bulk and extra cost of a full-blown smartwatch. Not only do they hold you accountable for your physical activity, many of the best fitness tracker models now include added health features such as sleep tracking, heart-rate monitoring and more. They'll then share that fitness tracking data with an app to give you a broader look at your overall fitness.

In a YouTube interview with entrepreneur Tom Bilyeu, Professor Sinclair asks are we treating the symptoms rather than the condition ageing that causes them?

Research has led to lifespans increasing, but older people often spend years in poor health.

Humans have around 20,000 genes. These provide the cell with instructions to make proteins. Not all of them are needed in every cell. Those that arent needed are turned off by process called epigenetics. This ensures genes are not active in inappropriate cell types. For example the COL1A1 gene codes to produce collagen, but only needs to be active in skin, cartilage and similar types of cell.

Sinclairs team believes that the loss of epigenetic information is the root cause of ageing. They have identified drugs that can reset a cells epigenetic status and reverse its age. These drugs can be delivered by a harmless virus to specific tissues or the entire body, thereby causing cells to act younger and wounds to heal faster.

Genes called sirtuins make enzymes that control how cells function and they can be used to turn off genes that hasten ageing.

Sever calorie restriction increases the lifespan of mice and yeast, but thats not really practical for humans.

However, Professor Sinclair says a short period of being hungry or stressed in other ways causes sirtuins to turn on the mechanism that repairs cell damage and resets the biological clock.

Other compounds can activate sirtuins. Resveratol, found in small amounts in red wine, activates sirtuins in mice when fed large doses. Metformin, used to control blood sugar levels in diabetics, acts in the same way. Diabetics who take metformin tend to outlive those who dont.

Next Sinclairs lab looked at the way mitochondria (the cell organelles that generate energy) operate. The levels of nicotinamide adenine dinucleotide (NAD+) in mitochondria dictate how long cell survive, but NAD+ declines with age.

Professor Sinclair and his co-researchers found that restoring NAD+ levels in mammals has a dramatically positive effect on the liver, heart, reproductive organs, kidney, muscles, and brain and nervous systems. Old mice given a NAD+ booster drug ran around like young mice within a few days.

They study the mechanisms by which the NAD+level repairs DNA and look for ways to improve this process. In particular, they study enzymes that deplete or increase NAD+ as potential tools to control the NAD+ level in the cells.

They have also actively looked for sirtuin activating compounds (STACs) and have discovered potent activators that raise NAD+ levels. They are testing these for their effects on ageing and age-related diseases.

But mice are not people, so it is too early to start taking NAD-boosting drugs until the results of human trials are completed.

Sinclairs advice for longevity is to avoid scans and X-rays as much as possible as they damage your DNA and get a little bit hungry from time to time. He spends four hours a week at the gym, include one hour doing yoga and an hour in the sauna.

He says the stress of jumping into cold water after the hot steam room and hot tub increases brown fat in his body. Brown fat has lots of mitochondria which raises the metabolic rate and helps to prevent excessive weight gain.

Pill to reverse ageing in 30 years? Why not, says Harvard professor Dr David Sinclair – Hindustan Times

There is no reason to accept ageing as inevitable, Harvard professor Dr David Sinclair said on Friday, adding that if a pill or a vaccine is not developed in the next 30 years to fight ageing, something must have gone terribly wrong.

Dr Sinclair, co-director of the Paul F Glenn Center for Biology of Aging Research at Harvard Medical School, and his team recently turned back the clock on aged eye cells in the retina to reverse vision loss in elderly mice.

Ageing is going to happen We are not going to live forever But can we try to live another 5 or 10 or 20 years longer, healthily? Absolutely... There is no law that says that we couldnt live longer, he said at the 18th Hindustan Times Leadership Summit.

Dr Sinclair, best known for his work on understanding why humans age and how to slow its effects, said it was important to declare ageing as a disease so that governments change laws to treat it with medicines and more funds are accessible for scientific work.

If it [a pill or a vaccine to reverse ageing] doesnt happen in the next 30 years, something must have gone terribly wrong, he said, adding that it was possible a medicine against ageing was already among us. We just need to have more evidence that they actually work the way we are hoping, the Harvard professor, who has featured in TIME magazines list of the 100 most influential people in the world, said.

His research has been primarily focused on sirtuins, a group of proteins that appear to be key in regulating the ageing process. In 1999, he was recruited to the Harvard Medical School, where he has been teaching ageing biology and translational medicine for ageing.

Dr Sinclair also shared tips on how to slow the process of ageing: dont eat three regular meals; exercise; lift some weights; use biomarker feedback; sleep well and reduce stress; and eat plants that have been stressed.

You may not want to skip breakfast, you may want to skip lunch or dinner... its different for every individual. If you are young, this is probably not for you, he said, adding that middle-aged people whose metabolism has slowed down should consider skipping meals strategically.

On the question of whether a vegetarian diet was better or a non-vegetarian regimen, he said: You do want your diet to look like what a rabbit might eat more than a lion.

According to a paper published in Nature, Dr Sinclair and his team used an adeno-associated virus as a vehicle to deliver into the retinas of mice three youth-restoring genes that are normally switched on during embryonic development. The three genes, together with a fourth one that was not used in this work, are collectively known as Yamanaka factors. This promoted nerve regeneration following optic-nerve injury in mice with damaged optic nerves, reversed vision loss in animals with a condition mimicking human glaucoma, and reversed vision loss in ageing animals without glaucoma.

Dr Sinclair said on Friday: We are trying to understand can we compress the last few years of life that are sick into a very short period... [The goal] is really not to keep us in nursing homes and being sick for longer. We are not extending old age, we are doing the opposite. Our goal is to extend youthfulness so that we can perhaps live to 90 or 100 and towards the very end, still be productive members of society playing whatever sport you want with your grandkids or great grandkids.

He added: Often, we think that we have reached our maximum life span as a society... that is not true... Over the 20th Century and continuing to today, there is a very linear and predictable increase in human longevity. Every time [people] have said that we have reached the maximum, we blow through that glass ceiling and we keep adding years to life. But they are not all healthy years.

The expert also gave more insights on mortality as a route to tackling ageing. We tend not to die as much as we used to from cardiac reasons, but the brain still ages at the normal rate and we dont do much about it Our approach is to treat the entire body with medicines and lifestyles that will keep every part of the body healthier and more youthful, the expert added. In my scientific opinion, around the age of 30, ageing starts to kick in.

On being asked about the nature of supplements people should take in the quest to slow ageing, the he said: Go with a company that has a good reputation Go for the very pure molecules. He added that resveratrol, a chemical found in red wine, appeared to show benefits in terms of anti-ageing properties. He, however, said that right meals and exercise seem to be the best bet against ageing at this point.

The proof-of-concept study published in Nature demonstrates the epigenetic reprogramming of complex tissues, such as the nerve cells of the eye, to a younger age when they can repair and replace tissue damaged from age-related conditions and diseases. Elaborating on the study in mice, Dr Sinclair said that most of our longevity is determined by our epigenome and not by our DNA.

While the DNA holds instructions for building proteins, epigenome comprises all of chemicals that are added to ones DNA to regulate the activity.

Reversing vision loss by turning back the aging clock – FierceBiotech

Aging has implications for a wide range of diseases. Researchers have been looking for ways to halt the aging process for millennia, but such methods remain elusive. Scientists at Harvard Medical School have now offered a glimmer of hope that the aging clock in the eye could be reversedat least in animals.

By reprogramming the expression of three genes, the Harvard team successfully triggered mature nerve cells in mice eyes to adopt a youthful state. The method reversed glaucoma in the mice and reversed age-related vision loss in elderly mice, according to results published in Nature.

GenScript ProBio is the bio-pharmaceutical CDMO segment of the worlds leading biotech company GenScript, proactively providing end-to-end service from drug discovery to commercialization with professional solutions and efficient processes to accelerate drug development for customers.

If further studies prove out the concept, they could pave the way for therapies that employ the same approach to repair damagein other organs and possibly treat age-related diseases in humans, the team said.

The researchers focused on the Yamanaka factors, which are four transcription factorsOct4, Sox2, Klf4 and c-Myc. In a Nobel Prize-winning discovery, Shinya Yamanaka found that the factors can change the epigenomehow genes are turned on or offand can thereby transform mature cellsback to a stem cell-like state. It has been hypothesized that changes to the epigenome drive cell aging, especially a process called DNA methylation, by which methyl groups are tagged onto DNA.

Past researches have tried to use the four Yamanaka factorsto turn back the age clock in living animals, but doing so caused cells to adopt unwanted new identities and induced tumor growth.

To test whether the approach works in living animals, the scientists used adeno-associated virus to deliver the three genes into the retina of mice with optic nerve injuries. The treatment led to a two-fold increase in the number of retinal ganglion cells, which are neurons responsible for receiving and transmitting visual information. Further analysis showed that the injury accelerated DNA methylation age, while the gene cocktail counteracted that effect.

Next the scientists tested whether the gene therapy could also work in disease settings. In a mouse model of induced glaucomawhich is a leading cause of age-related blindness in peoplethe treatment increased nerve cell electrical activity and the animals visual acuity.

But can the therapy also restore vision loss caused by natural aging? In elderly, 12-month-old mice, the gene therapy also restored ganglion cells electrical activity as well as visual acuity, the team reported.

By comparing cells from the treated micewith retinal ganglion cells from young, 5-month-old mice, the researchers found that mRNA levels of 464 genes were altered during aging, and the gene therapy reversed 90% of those changes. The scientists also noticed reversed patterns of DNA methylation, which suggests that DNA methylation is not just the marker but rather the driver behind aging.

What this tells us is the clock doesn't just represent timeit is time. If you wind the hands of the clock back, time also goes backward, the studys senior author, David Sinclair, explained in a statement.

The study marks the first time that glaucoma-induced vision loss was reversednot just slowedin living animals, according to the team.

RELATED:Reprogrammed skin cells restore sight in mouse models of retinal disease

Other researchers are also studying regenerative approaches to treating eye diseases. A research group at the Centre for Genomic Regulation in Barcelona just showed that by modifying mesenchymal stem cells to express chemokine receptors Ccr5 and Cxcr6, retinal tissue could be saved from degeneration.

The idea of reversing age-related decline in humans by epigenetic reprogramming with a gene therapy is exciting, Sinclair said. The Harvard researchers intend to do more animal work that could allow them to start clinical trials in people with glaucoma in about two years.

Our study demonstrates that it's possible to safely reverse the age of complex tissues such as the retina and restore its youthful biological function, Sinclair said. If affirmed through further studies, these findings could be transformative for the care of age-related vision diseases like glaucoma and to the fields of biology and medical therapeutics for disease at large.
