Indian-origin doc performs life-saving heart op on US actor

December 2, 2013

Indian-originWashington, Dec 2: In a first, an Indian-origin doctor in the US has performed a unique "life-saving" heart procedure - that involves injecting the patient's own stem cells into the organ - on Hollywood actor Ernie Lively.

Amit Patel from the University of Utah performed the historic procedure on Lively - 'Gossip girl' actress Blake Lively's father - using new technique of retrograde gene therapy on a human heart to repair damaged muscle and arteries.

The 66-year-old actor has credentials that include a long list of TV and film appearances, including Passenger 57 and the Sisterhood of the Travelling Pants.

He had suffered a massive heart attack in 2003, which left him functioning on half a healthy heart. As time marched on, his ejection fraction - the measurement of the percentage of blood leaving the heart each time it contracts - continued to decline.

Lively connected with Patel, director of Clinical Regenerative Medicine and Tissue Engineering and an associate professor in the Division of Cardiothoracic Surgery at the University of Utah School of Medicine.

Lively became a patient of Patel's in February, when Patel saved Lively's life after a complication with an angiogram left the actor with a severed aorta and problems with his coronary arteries.

This month, Lively got his wish when he became the first patient in the world to undergo retrograde gene therapy at University of Utah Hospital, a novel procedure designed to deliver stem cells to the heart to repair damaged muscle and arteries in the most minimally invasive way possible.

Patel started investigating cell and gene-based therapies for the treatment of heart disease 12 years ago, but only recently received FDA approval to try the therapy on Lively.

The first successful procedure was performed on Lively on November 7.

"It's incredible. Imagine having a heart procedure that can potentially regenerate or rejuvenate your heart muscle - and it's done as an outpatient procedure," said Patel.

Patel uses a minimally invasive technique where he goes backwards through a patient's main cardiac vein, or coronary sinus, and inserts a catheter.

He then inflates a balloon in order to block blood flow out of the heart so that a very high dose of gene therapy can be infused directly into the heart. The unique gene therapy doesn't involve viruses (a rarity for gene therapy, Patel notes) and is pure human DNA infused into patients.

The DNA, called SDF-1, is a naturally occurring substance in the body that becomes a homing signal for a patient's body to use its own stem cells to go to the site of an injury.

Once the gene therapy is injected, the genes act as "homing beacons." When the genes are put into patients with heart failure, they marinate the entire heart and act like a look out, he said.

"I woke up this morning and told my wife, 'I haven't felt this good in years," said Lively after returned home where he is recovering.

Drinking coffee may help reduce the risk of certain digestive disorders, including gallstone disease and pancreatitis, a new study has suggested.

The study from the Institute for Scientific Information on Coffee (ISIC) also highlighted other beneficial effects that coffee consumption may have on the process of digestion, including supporting gut microflora and promoting gut motility.

"Data indicates benefits against common digestive complaints such as constipation, as well as a potential reduction in the risk of more serious conditions like chronic liver diseases," said study author Carlo La Vecchia from the University of Milan in Italy.

Gallstone disease is a common digestive disorder, caused by the accumulation of gallstones in the gallbladder or bile duct, which affects approximately 10-15 per cent of the adult population.

While the mechanism by which coffee may protect against gallstone disease is not yet known, it has been observed that the risk for the condition declines with increasing daily consumption of coffee, the researchers said.

Caffeine is thought to play a role in these associations, as the same effect is not observed with decaffeinated coffee.

A common question among consumers and focus area for research is whether coffee is associated with heartburn or gastro-oesophageal reflux disease (GORD).

While a small number of studies have suggested an association between coffee drinking and GORD, the majority of studies reviewed suggest that coffee is not a major trigger of these conditions.

The report also reviewed a growing area of health and nutrition research, namely: the effect of coffee on the gut microflora (microorganism populations).

Recent studies suggest that populations of the beneficial gut bacteria Bifidobacterium spp, increase after drinking coffee.

The findings showed the dietary fibre and polyphenols found in coffee, support the healthy growth of microflora populations.

Additional research findings highlighted that coffee consumption is thought to stimulate digestion by encouraging the release of gastric acid, bile and pancreatic secretions.

Coffee is one of the most widely researched components of the diet, and its effect on digestion remains a growing area of research, the researchers noted.

Clinician-scientists have found that Irish patients admitted to hospital with severe coronavirus (COVID-19) infection are experiencing abnormal blood clotting that contributes to death in some patients.

The research team from the Royal College of Surgeons in Ireland found that abnormal blood clotting occurs in Irish patients with severe COVID-19 infection, causing micro-clots within the lungs.

According to the study, they also found that Irish patients with higher levels of blood clotting activity had a significantly worse prognosis and were more likely to require ICU admission.

"Our novel findings demonstrate that COVID-19 is associated with a unique type of blood clotting disorder that is primarily focussed within the lungs and which undoubtedly contributes to the high levels of mortality being seen in patients with COVID-19," said Professor James O'Donnell from St James's Hospital in Ireland.

In addition to pneumonia affecting the small air sacs within the lungs, the research team has also hundreds of small blood clots throughout the lungs.

This scenario is not seen with other types of lung infection and explains why blood oxygen levels fall dramatically in severe COVID-19 infection, the study, published in the British Journal of Haematology said.

"Understanding how these micro-clots are being formed within the lung is critical so that we can develop more effective treatments for our patients, particularly those in high-risk groups," O'Donnell said.

"Further studies will be required to investigate whether different blood-thinning treatments may have a role in selected high-risk patients in order to reduce the risk of clot formation," Professor O'Donnell added.

According to the study, emerging evidence also shows that the abnormal blood-clotting problem in COVID-19 results in a significantly increased risk of heart attacks and strokes.

As of Friday morning, the cases increased to 20,612 cases in Ireland, with 1,232 deaths so far, according to the Johns Hopkins University.

Dear parents, if you want your children to have proper sleep, read this carefully. Joining a growing list of studies that tell parents to shun devices at bed-time, researchers say that children who use devices and decide what time they go to sleep, achieve less sleep and feel more sleepier the following day than their peers.

The study of children in this age-group (aged 11 to 13 years), published in the New Zealand Medical Journal, found most (72 per cent) of the 163 students interviewed by University of Otago researchers achieved recommended guidelines of an average 9 to 11 hours sleep nightly over one week.

"But that also means that almost one in four students did not achieve sleep within these guidelines, which highlights an area for improvement," said study researcher Kate Ford.

However, consistent with previous research in 15 to 17-year-old New Zealanders, the study results show less sleep on the nights where devices are used in the hour before bed.

According to the researchers, students who used devices before going to sleep were also more likely to report that they felt sleepy the following morning. Watching television before bed had no significant effect on sleep length.

There were also some interesting observations over the weekends where students went to bed later but woke later achieving similar sleep length to the school days, the researchers said.

A small group of students (six per cent) who reported less than seven hours of sleep, including a small number reporting not sleeping at all, according to the study,

Therefore, while the average across the week of 72 per cent of students reporting adequate sleep is reassuring, it is far from the goal of every child achieving sleep within the recommended guidelines," Ford said.

Dr Paul Kelly, head of the Sleep Health Service at Canterbury District Health Board, supervised the study and explained that the foundations for good health are based on proper nutrition, regular exercise and good sleep quality.

Sleep quality is often overlooked as a contributory factor to poor health.

"The study findings suggest the need for parental guidance around bedtimings and moderation of the use and availability of electronic devices before bed," Kelly said.

"Respect and protect your sleep, as good daytime functioning is reliant on adequate sleep," Kelly added.
