Health24.com | KZN woman who received life-saving kidney wants to encourage people to become donors

A 45-year-old woman from Pietermaritzburg got a kidney transplant in June 2018 after nearly six years of suffering with renal problems.

Former tennis coach, Hayley Herman discovered she had kidney problems in 2012 after going for X-rays and blood tests for a shoulder injury – with the tests picking up she had renal failure and high levels of creatinine in her body which signifies impaired kidney function.

After initially being misdiagnosed by a specialist in Howick, she had an allergic reaction to Vancomycin, an antibiotic prescribed to patients with acute renal failure.

“I had a severe skin reaction,” she said.

“It was a rare allergy known as red man syndrome where my skin was red and inflamed which caused my whole body to swell, I lost a lot of hair as well.”

It was only in 2013 after she saw another specialist named Dr Siddique that she received the correct medical treatment for her condition.

“Dr Siddique was the nephrology specialist who changed all my medication and placed me on haemodialysis (a process of purifying the blood),”

Hayley has always been a sportswoman and took part in satellite tennis tournaments in South Africa. She also did mountain bike racing for about two years.

“I played professional tennis for 14 years and competed in tournaments in Gauteng, the Western Cape and KwaZulu-Natal before taking part in mountain bike racing from 2009 to 2010,” she said.

The dialysis cost R1 800 for each four-hour session, with the process leaving her feeling drained and exhausted.

“I had dialysis three times a week. It was really painful, especially the two needles that are placed in your arm for the sessions.

“[Patients on dialysis] are also restricted to 500ml of liquid a day.”

Hayley’s condition also caused her great emotional turmoil and she often felt ostracised and alone.

“It was very hard on my parents as they felt so helpless. It was a difficult time as my family didn’t support me except for my Mom and Dad,” she said.

She was put on the donor list in October 2017 and found it really hard to get a match because there were only a few available donors.

“I was totally isolation at home for three months after my transplant on 2 June. I’m still in slight isolation, having to wear a mask when in public places because I’m always susceptible to infections.”

After her ordeal and life-saving transplant, she wants to encourage others to become donors.

“[Organ] donors are so important they can save up to nine people’s lives,”

“It’s so easy to become a donor and it can be done online, just go to the Organ Donor Foundation or call the toll-free hotline on 0800 226 611.”

9 Standing Desk Ideas That Just Might Save Your Health (and Your Wallet)

We’ve all heard the bad news about sitting. It's the "new smoking," as many news articles have put it. It's been linked to upping your risk for cancer, diabetes, and early death, even if you exercise, according to recent research. It may even affect your mental health.

But let's face it: many of us have desk jobs, and there's not much we can do about sitting at our computers unless we quit our jobs—or buy a fancy standing desk. The problem? These desks aren't exactly affordable, with some of the more pricey models clocking in at upwards of $500.

But, thanks to the ingenuity of the Internet and some smart product designers, there are now plenty of ways to stand more without breaking the bank. Here are our favorite DIY and budget-friendly desks that won't cost you a small fortune.

New insight into why galaxies stop forming stars

Galaxy clusters are rare regions of the universe consisting of hundreds of galaxies containing trillions of stars, as well as hot gas and dark matter.

It has long been known that when a galaxy falls into a cluster, star formation is fairly rapidly shut off in a process known as “quenching.” What actually causes the stars to quench, however, is a mystery, despite several plausible explanations having been proposed by astronomers.

A new international study led by astronomer Ryan Foltz, a former graduate student at the University of California, Riverside, has made the best measurement yet of the quenching timescale, measuring how it varies across 70 percent of the history of the universe. The study has also revealed the process likely responsible for shutting down star formation in clusters.

Each galaxy entering a cluster is known to bring some cold gas with it that has not yet formed stars. One possible explanation suggests that before the cold gas can turn into stars, it is “stripped” away from the galaxy by the hot, dense gas already in the cluster, causing star formation to cease.

Another possibility is that galaxies are instead “strangled,” meaning they stop forming stars because their reservoirs cease getting replenished with additional cold gas once they fall inside the cluster. This is predicted to be a slower process than stripping.

A third possibility is that energy from the star formation itself drives much of the cold gas fuel away from the galaxy and prevents it from forming new stars. This “outflow” scenario is predicted to occur on a faster timescale than stripping, because the gas is lost forever to the galaxy and is unavailable to form new stars.

Because these three different physical processes predict galaxies to quench on different relative timescales over the history of the universe, astronomers have postulated that if they could compare the number of quenched galaxies observed over a long time-baseline, the dominant process causing stars to quench would more readily become apparent.

However, until recently, it was very difficult to find distant clusters, and even harder to measure the properties of their galaxies. The international Spitzer Adaptation of the Red-sequence Cluster Survey, or SpARCS, survey has now made a measurement of more than 70 percent of the history of the universe, accomplished by pioneering new cluster-detection techniques, which enabled the discovery of hundreds of new clusters in the distant universe.

Using some of their own newly discovered SpARCS clusters, the new UCR-led study discovered that it takes a galaxy longer to stop forming stars as the universe gets older: only 1.1 billion years when the universe was young (4 billion years old), 1.3 billion years when the universe is middle-aged (6 billion years old), and 5 billion years in the present-day universe.

“Comparing observations of the quenching timescale in galaxies in clusters in the distant universe to those in the nearby universe revealed that a dynamical process such as gas stripping is a better fit to the predictions than strangulation or outflows,” Foltz said.

To make this state-of-the art measurement, the SpARCS team required 10 nights of observations with the W. M. Keck Observatory telescopes (10 meters in diameter) in Hawaii, and 25 nights of observations with the twin Gemini telescopes (8 meters in diameter) in Hawaii and Chile.

“Thanks to the phenomenal investment in our work by these observatories, we now believe we have a good idea of how star formation stops in the most massive galaxies in clusters,” said Gillian Wilson, professor of physics and astronomy at UCR and leader of the SpARCS survey, in whose lab Foltz worked when the study was done. “There are good reasons, however, to believe that lower-mass galaxies may quench by a different process. That is one of the questions our team is working on answering next.”

The team has been awarded 50 additional nights of Gemini time and a $1.2 million grant from the National Science Foundation to study how star formation stops in more regular-mass galaxies. Wilson was also awarded Hubble Space Telescope observations and a NASA grant to analyze high-resolution images of the quenching galaxies.

The research paper is published in the Astrophysical Journal.

To see what’s right in front of you, your brain may need some rewiring

Life-changing moments are also brain-changing moments: everything from a first kiss to a last goodbye modifies cells within the skull. The capacity to learn and remember, however, extends beyond the profound experiences that we lament or treasure. In fact, a new study led by Rockefeller scientist Charles D. Gilbert suggests that even when we’re not consciously forming new memories, our brains can change in important ways, altering how we interpret and interact with the world.

“Some connections in brain are fixed after a period in early life, known as the critical period,” says Gilbert, the Arthur and Jane Ross Professor of Neurosciences and Behavior. “Others are changing throughout life, and play an important role in encoding information in our brain as we encounter new experiences.”

Perceiving is believing

The study, published in the Proceedings of the National Academy of Sciences, focused on perceptual learning, a process that involves tuning the senses to better perceive the subtleties of various sights, sounds, and smells. Most of the time, we’re not aware that we’ve become better at distinguishing between two different shapes, for instance; but over time, with repeated exposure, this type of unconscious learning indeed takes place.

Scientists have long known that the brain can remodel itself, both as a result of normal memory formation and as a way to recover from brain damage. Gilbert had previously shown, for example, that when recovering from brain injury, neurons grow new axons, the threads that transmit signals to other cells. And he has long believed that this type of change might also occur under normal circumstances.

“We had always suspected that this ability to form new connections in the adult brain isn’t something that just evolved as a way to recover after injury,” says Gilbert. “Rather, it’s a mechanism that we’re using in our brains all the time.”

What’s more, disruptions to that mechanism could underlie some brain disorders, Gilbert says. “This type of neuronal flexibility happens in areas outside of perception,” he notes. “So if that mechanism gets disturbed, it may account for behavioral disorders such as autism and schizophrenia.”

Can you see it?

To test whether remodeling occurs in brain regions devoted to vision, Gilbert and his colleagues challenged two macaque monkeys to perceive elements of order within otherwise disordered scenes. During experiments, the monkeys viewed two pictures side by side. Both contained a frenzy of dashes, but in one image some of these dashes came together to form a cohesive line. The monkeys’ task was to identify the line — and the fewer dashes it contained, the harder it was to spot.

Initially, the monkeys succeeded only during the easy rounds, when the lines consisted of nine dashes. With weeks of training, however, they mastered increasingly difficult trials, and one animal was eventually able to spot a line only three dashes long.

“The animal didn’t need a reward to move his eye in the direction of the image that contained a line,” says Gilbert. “Just by doing the same task over and over, he improved.”

Throughout the experiment, the researchers tracked cellular changes in the visual cortex, a brain region that receives and processes signals from the eye. They found that, as the animals got better at the task, visual cortex neurons sprouted new axons and shed some old ones. These findings show that the circuitry of the adult brain is constantly changing, a quality known as plasticity.

“We’ve always known the brain needs some degree of plasticity through adulthood so that we can acquire new memories,” says Gilbert. “But it turns out that plasticity is more ubiquitous than we initially thought.”

Health24.com | Study: This easy fix could be the unexpected answer to low sex drive

If your sex drive has been dipping, a new Italian study suggests there may be an easy fix: Light therapy.

Scientists recruited 38 men diagnosed with hypoactive sexual desire disorder or sexual arousal disorder – two conditions characterised by a lack of interest in sex – and provided bright light treatment to half of them.

For 30 minutes each morning, these men sat in front of a light box that exposed them to 10 000 lux of light. (For comparison, direct sunlight can reach up to 100 000 lux and a cloudy day is about 1 000 lux.)

After two weeks, the men receiving the bright light treatment reported sexual satisfaction scores that were three times higher than when they began the experiment. (The guys in the other group showed only modest increases.)

The bright light group also saw a boost in their testosterone levels – which is vital to increasing libido, says lead researcher Dr Andrea Fagiolini from the University of Siena.

When your body is exposed to bright light, it produces more of a chemical called the luteinising hormone (LH). And more LH may lead to greater production of testosterone, Dr Fagiolini says.

This doesn’t mean you can crank up your sex drive simply by rolling up the window shades: You should shoot for roughly the same intensity of light used by the study participants.

You can find that level in a personal light box, which you can purchase online and use at home.

Just make sure you talk to your doctor first. Before you get the go-ahead, he or she might test you for other problems like low testosterone, thyroid problems or kidney disease, all of which can cause a drop in libido, too.

Health24.com | 5 bedtime beverages that will help you lose weight

Poor sleep is tied to weight gain, skewed hormones, next-day hunger, and blood sugar and insulin issues, says Bridget Murphy, registered dietitian and nutritionist at NYU Langone Medical Center.

To score some quality sleep, you’ve got to be careful about what you drink before you crash. While you probably know that having caffeine and sugar too close to bedtime can mess with your sleep, other nutrients can actually help you build muscle, improve your blood sugar stability and burn fat.

Read more: Do these sleep myths really work to get you to bed?

Here are five beverages to drink at night if you’re looking to lose weight:

1. Milk

A glass of milk (warm or not) can help you sleep more soundly, thanks to a healthy dose of tryptophan and calcium, says Murphy.

And more sleep means less next-day cravings. Milk’s casein protein is slow to digest, which could help you build muscle all night long, according to research from Medicine and Science in Sports and Exercise.

The result: A faster metabolism and easier weight loss, says Murphy.

2. Grape juice

A small glass of 100% grape juice before bed may help you sleep and burn fat as you dream, says Murphy. Research published in Cell Reports suggests that insulin secretion at night (caused by consumption of simple carbs, like juice) regulates the body’s circadian rhythms.

And a 2015 International Journal of Obesity study found that an antioxidant contained in grapes, converts kilojoule-storing white fat into kilojoule-burning brown fat. It’s a one-two punch.

In case you’ve heard, yes, wine is also rich in resveratrol. Unfortunately, alcohol isn’t the best pre-bed drink. In one University of Melbourne study, sleepers who drank booze before bed exhibited nighttime brain wave patterns similar to people who received small electric shocks all night long.

3. Chamomile tea

A hot mug of this sleep-inducing tea increases your body’s levels of glycine, a neurotransmitter that relaxes your nerves and acts as a mild sedative. Another cool trait of chamomile: It spikes your core body temperature so that your system responds by drastically cooling itself, lulling you to sleep.

What’s more, chamomile has been linked to improved glucose control and can help you lose weight, says Murphy. Just make sure that any tea you drink before bed is caffeine-free.

4. Kefir

Made from fermented milk, this probiotic-rich beverage works on your gut microbiome to increase levels of healthy bacteria, promote proper digestion, and help you to absorb vitamins and minerals more effectively, says Murphy.

Research published in the British Journal of Sports Medicine has also tied the yoghurt-like beverage to improved sleep and better exercise performance.

5. Soy protein shake

Soy, in milk or protein powder form, is brimming with the amino acid tryptophan.

According to Birmingham University research, it can improve sleep quality by acting as a precursor to drowse-inducing melatonin, says Murphy. She notes that apart from helping you drift off, tryptophan also decreases cortisol levels to help fight belly fat and lose weight.

For the best benefits, include some Greek yoghurt in your protein shake. It’ll supply your muscles with a generous helping of casein protein for better post-workout recovery, she says.

Health24.com | New tuberculosis vaccine in sight

It took 100 years but a new vaccine for the world’s top infectious disease killer, tuberculosis (TB), is in sight. 

“In my opinion this meeting is one of the most significant events in TB history [because of] the spectacular results presented today [on progress towards a TB vaccine] for the first time in a century,” said Professor Thomas Ottenhoff from the global non-profit The Tuberculosis TB Initiative. 

He was speaking at a press briefing on Tuesday in The Netherlands ahead of the 49th Union World Conference on Lung Health where the results for a new TB vaccine were presented. 

Developed by Glaxo Smith Kline (GSK) and Aeras the M72 vaccine is the most successful vaccine candidate for TB in a century: there was a 54% reduction in TB disease in vaccinated study participants. 

This is according to GSK’s Marie-Ange Demoitie who said these results had come after the pharmaceutical company, partnering with non-profit Aeras, had been working on the vaccine for two decades. 

The only existing TB vaccine, known as BCG, was developed a century ago and prevents serious forms of TB in children but has not worked to protect adults. 

“Modelling [studies] have already shown that a 50% effective vaccine, which this is, could save millions of lives and avert tens of millions of cases of TB,” said Dr Ann Ginsberg from the International Aids Vaccine Initiative. 

Since 2014 researchers have studied the protective effect of M72 in 3 500 people in three African countries: South Africa, Kenya and Zambia. 

The results now have to be confirmed in a bigger study before it can be rolled out in counties. 

According to the Union Against Tuberculosis and Lung Disease’s scientific director Dr Paula Fujiwara, an effective vaccine is essential to meet the United Nations’ target of ending TB by 2030. 

“[To end TB] we need much more of the promising news we are hearing today and TB research and development needs to be drastically stepped up,” she said.

Study explores infant body position and learning

A developmental psychologist at the University of California, Riverside, has completed a study that is the first to measure how often infants spend time in different body positions over the first year of life.

The study, published in the journal Infancy, aims to understand how the physical context of infants’ everyday experiences — in particular, how much time they spend in different body positions — changes over the course of the first year and how these changes are predicted by infants’ developing motor skills.

“I was surprised to find that 3-month-olds are held almost half of their waking days” said John Franchak, an assistant professor of psychology, who performed the study. “Twelve-month-olds are held much less frequently and spend most of their time on the ground. How often infants play, crawl, walk, or sit changes how they interact with objects and changes, too, the physical way in which they interact with other people.”

Specifically, Franchak found that sitting, upright, and prone (belly towards the ground regardless of contact with the ground) accounted for less than 7 percent of the 3-month-old infant’s day. By 12 months, these positions accounted for 62 percent of the infant’s day.

The cross-sectional study sought to understand what a 12-month-old learns and how this learning differs from that of, say, a 3-month-old infant, based on their everyday experiences. Toward that end, the study tested separate groups of 3-month-olds, 6-month-olds, 9-month-olds, and babies that were a year old. It used data acquired for 95 babies from across the United States.

The study used an innovative approach to acquire this data: the infants’ caregivers were sent text messages five times a day for a week to inquire on what the baby was doing at that moment. The caregivers electronically reported infant body positions immediately thereafter in brief one-minute surveys. They also reported infants’ location — whether the infants were on the floor or up on a raised surface — and the onset of sitting, crawling, and walking. The study is the first to use this method, called ecological momentary assessment, to measure infants’ behaviors.

“We have plenty of data on what babies do in the lab, where we measure their development by doing some assigned task,” Franchak said. “What we don’t know is what drives that development, what happens in the days, hours, and minutes they are at home, where they experience a number of things that lets them learn. Until this study, we didn’t know how often babies sit, crawl, and stand in everyday life, outside the lab. The ecological momentary assessment the study used offers a better sense of infants’ actual lives versus a slice of life in the lab, and gives a more realistic distribution of their different types of body positions and experiences. Understanding these differences allows us to build better theories about how infants develop and learn from the world.”

Franchak explained that body positions change dramatically over the first year of life, and much of that change results from infants acquiring new motor skills. Typically, babies begin to sit around 6 months of age, crawl at around 8 months, stand around 11 months, and walk when they are a year old. It is important to study infant body position, he said, because changes in how babies interact with the world change their opportunities for learning. Learning to sit is linked with better object perception. Learning to walk is linked with improved language ability.

“The amount of time infants spend in different positions shapes their visual and manual activity — impacting perceptual, cognitive, and social development — and reflects opportunities to practice and develop motor skills,” Franchak said. “For example, infants rarely see faces while playing on the ground in sitting, upright, and prone positions, but see faces more often when held or sitting off the ground as in a high chair.

“Further, infants who can sit independently at 6 months spend more time sitting in daily life. This allows them to manipulate objects more frequently and receive nearly twice as much opportunity to experience the richer visual-manual exploration of objects than prone or supine infants,” he added. “Learning to walk changes social interactions with caregivers and predicts improvement in infants’ spatial cognition.”

Franchak cautioned that caregivers play an important role in influencing the study’s results. The study’s youngest infants are entirely dependent on caregivers to change their body position. For older infants, choosing to sit or stand is often an option only if their caregivers provide the opportunity.

“I can’t say enough about how much caregivers are doing in determining what positions their babies are in,” he said. “Caregivers act in response to how they perceive their children. When they see their babies have acquired certain skills, they take action accordingly to accommodate these skills. Caregivers and their babies then negotiate constantly on how best to proceed thereafter.”
