Country’s first Vascular surgery within the womb performed in Lucknow
Country's first vascular surgery within the womb was performed by team of doctors at Sanjay Gandhi's Post Graduate Institute of Medical Science's department of maternal and reproductive health.
The doctors successfully blocked blood supply to a giant tumor over the placenta which had caused anemia in baby besides enlarging her heart. The impact was that the heart had overgrown by 135% of the expected size and would have eventually caused cardiac and respiratory failure.
Head, maternal and reproductive health department, Prof Mandakini Pradhan shared that the procedure is technically known as percutaneous embolization of a giant placental chorioangioma. The case relates to a seven month pregnant woman named Vandana whose belly was bigger than expected.
Her routine check-up and some ultrasound tests showed presence of excess placental fluid. On examining her, a giant placental tumor was the cause of trouble. The process, conducted in the mid of December, was done over a 4 mm spot lasted for 15 seconds to end the problem. Efforts yielded positive result and Vandana delivered a healthy baby girl on December 31.
On Tuesday, the baby was examined in a follow-up check up and declared healthy by the doctors.
Prof Pradhan recalled that the tumor had deprived the baby of her nutrition causing acute anaemia in her. "As a result, the baby's heart had enlarged which was causing immense pressure on the lungs as well. The only way to treat the baby was to conduct a percutaneous embolization. Though the procedure had been used seven times by experts across the world, no one in India had conducted it," said said.
Patient family was apprised about the probable option and allowed to take the decision. Vandana's husband Vivek Shukla shared that private doctors had given up on the baby. "Three of them refused to attend my wife the last one told us that they will not be able to save the baby. Some of them infact believed that there was a twin baby inside," he said adding that he brought his wife to SGPGI on the reference of a family friend.
"In PGI, we were told that if everything underwent the way it is, there was just 10% chances of baby's survival while taking the risk of new procedure meant a 50-50 chance. Therefore, we went ahead," said Vandana, the mother.
When the family agreed, the doctors got on to review of literature to create a protocol for the procedure and arrange for the materials needed. The key to child survival in the case was use of a tissue glue (substances used to bind tissue one tissue to another) called n-Butyl-2-Cyanoacrylate.
"The glue is commonly used in adult surgical procedures and was provided by radiology department," shared Dr Neeta, a team-mate.
The team undertook two rounds of dummy surgery on the patient as per the protocol using plain water. "Since we had just 4 mm space and 15 seconds time to inject the glue at the spot, there was no room for making mistakes," recalled Dr Pradhan who said that the embolization process was taken up in the mid of December.
"We extracted blood sample of the baby to test haemoglobin levels so that the required quantity could be transfused," she said. The next step was to examine the impact of our work and we were bang on. Regular monitoring showed that nutrients flow to the baby had normalized.
"In two weeks, heart assumed its normal shape which allowed us to plan for a caesarean section and thus a healthy baby girl was born on December 31," said Dr Pradhan.
The team claimed that scientific literature has documented only seven such cases across the world of which none are from India. Six of these babies have survived.

In US, fear of big babies sees a spurt in c-sec
aty Clemens wanted to have a natural, drug-free childbirth. Then an ultrasound suggested her baby would weigh 11.5 pounds, and her doctors insisted she schedule a cesarean section.
On learning the possible birth injuries that could befall such a large baby during a vaginal birth, Clemens relented. But when Sam was delivered by C-section, the doctors were in for a small surprise. Sam weighed in at 7 lbs. 13 ounces — nearly four pounds less than expected.
Clemens, now 37, a lawyer from Columbia, now says the surgery was unnecessary and probably caused her son to have breathing problems at birth, a complication more common in C-section babies.
However, Clemens is not alone. Last month, a research showed that mothers who believed they were having large babies were nearly five times more likely to ask for a C-section, even though the vast majority of their babies weighed less than 4,000 grams, which is the medical definition of a large baby. Fewer than 8% of babies born in the United States meet the medical definition of a large baby. But exaggerated estimates of fetal birth weight may be playing a role in the nation's high C-section rates, said Dr Eugene R. Declercq. In the US, nearly one in three babies are born by C-section.
"When you're told your baby will be large, it conjures up images of more pain, and risks and complications that might harm you and your baby. Women understandably might want to avoid that," said professor Erika R. Cheng.
Guidelines from the American College of Obstetricians and Gynecologists in 2014 say that a suspected large baby is only "rarely" an indication for a cesarean delivery. The concerns about vaginal delivery of large babies are real. Large babies born vaginally are at risk of shoulder dystocia, which is when the head is delivered but the shoulders are stuck. This can result in nerve damage that causes a loss of movement or weakness in the arms. But the guidelines urge caution in the use of ultrasound scans to estimate fetal weight, noting that the scans are associated with cesareans, and they urge doctors to use them "sparingly" and to counsel patients that scans are imprecise during the third trimester.

Guilt-free sugary treats in the offing
Guilt-free sugary treats may be on the horizon after scientists, including one of Indian-origin, have discovered an enzyme that can stop the toxic effects of sugar in various organs of the body.
The finding could lead to the development of therapeutics for obesity and type 2 diabetes, researchers said. The enzyme, named glycerol 3-phosphate phosphatase (G3PP), plays a central role in controlling glucose and fat utilisation.
Led by doctors Marc Prentki and Murthy Madiraju, the research team has demonstrated that G3PP is able to detoxify excess sugar from the cells.
"When glucose is abnormally elevated in the body, glucose-derived glycerol-3 phosphate reaches excessive levels in cells, and exaggerated G3PP metabolism can damage various tissues," said Prentki. "G3PP is able to breakdown a great proportion of this excess glycerol phosphate to glycerol and divert it outside the cell, thus protecting the insulin producing beta cells of pancreas and various organs from toxic effects of high glucose levels," he added.
Mammalian cells use glucose and fatty acids as the main nutrients, which governs many physiological processes such as insulin secretion by beta cells, production of glucose in liver, storage of fat in adipose tissue and breakdown of nutrients for energy production. Derangement of these processes leads to obesity, type 2 diabetes and cardiovascular diseases. The beta cells sense changes in blood glucose levels and produce insulin according to body demand.
However, when beta cells are presented with excess glucose and fatty acids, the same nutrients become toxic and damage them, leading to their dysfunction and diabetes.
"By diverting glucose as glycerol, G3PP prevents excessive formation and storage of fat and it also lowers excessive production of glucose in liver," said Madiraju. "It is extremely rare since the 1960s that a novel enzyme is discovered at the heart of metabolism of nutrients," he said.

சென்னைவாசிகளின் உயிரை பறிப்பதில் மாரடைப்பு முதலிடம் !
சென்னையில் இயற்கையாக உயிரிழந்தவர்களின் எண்ணிக்கையில், 54 சதவீதம் பேர் மாரடைப்பு காரணமாக மரணம் அடைந்திருப்பதாக சென்னை மாநகராட்சி புள்ளி விபரம் தெரிவிக்கிறது.
கடந்த ஆண்டு சென்னையில் மட்டும் 59 ஆயிரத்து 486 பேர் இயற்கை மரணம் அடைந்துள்ளனர். அதில் சரிபாதியாக இதய நோய் பாதிப்பால் உயிரிழப்பை சந்தித்துள்ளனர். அதாவது 32 ஆயிரத்து 339 பேர் மாரடைப்பு காரணமாக மரணமடைந்துள்ளனர். இதில் 18 ஆயிரத்து 816 பேர் ஆண்கள், பெண்கள் 13 ஆயிரத்து 523 பேர்.
இயற்கையாகவே ஆண் ஹார்மோன்கள் கெட்ட கொழுப்பை அதிகப்படியாக உற்பத்தி செய்வது, ஆண்களை மாரடைப்பு அதிகமாக தாக்க ஒரு காரணமாக அமைந்திருக்கிறது. அது தவிர புகைப்பது, மது அருந்துவது போன்ற பழக்கங்களும் ஆண்களுக்கு மாரடைப்பு ஏற்படுவதற்கான வாய்ப்புளை அதிகப்படுத்துகிறதாம்.
கடந்த 20 ஆண்டுகளுக்கு முன் இந்தியர்களுக்கு இதய நோய் தாக்குவது குறைவாக இருந்துள்ளது. தற்போதைய காலக்கட்டத்தில் இந்தியாவில் 25 முதல் 69 வயதுக்குட்பட்டவர்களில் 25 சதவீதம் பேர் மாரடைப்பு காரணமாக மரணம் அடைகிறார்கள் என்று ஒரு ஆய்வு தெரிவிக்கிறது. கடந்த 1990-ம் ஆண்டுகளில் காசநோய் இருந்த இடத்தில் தற்போது இதய நோய் இருக்கிறதாம். 1990 முதல் 2013-ம் ஆண்டு வரை இந்தியாவில் இதய நோய் பாதிப்புக்குள்ளானவர்களின் எண்ணிக்கை 138 சதவீதம் அதிகரித்துள்ளதாகவும் அந்த ஆய்வு கூறுகிறது.
மாரடைப்பு வருவதற்கு அதிகப்படியான டென்ஷன், உடல்பருமன், அதிகப்படியான சர்க்கரை, அதிகப்படியான ரத்த அழுத்தமும் ஒரு காரணமாக இருக்கிறது. இந்த நோய்கள் ஒன்றுக்கொன்று தொடர்புடைய நோய்கள் என்றும் மருத்துவர்கள் தெரிவிக்கின்றனர்.
மாரடைப்பு வருவதற்கு நெஞ்சில் ஏற்படும் அதிகப்படியான வலி மட்டுமே அறிகுறி அல்ல. அதிகப்படியாக வியர்த்தல், இடது தோள்பட்டையை ஒட்டிய பகுதிகளில் அதிகப்படியான வலி, தாடையில் வலி ஏற்படுவதும் கூட மாரடைப்புக்கான அறிகுறிகள். இது குறித்த விழிப்புணர்வும் மக்களுக்கு தேவை என மருத்துவர்கள் கூறுகின்றனர்.

Asthma, sleep apnea may weaken cornea
People with asthma, sleep apnea or Down syndrome are at higher risk of developing an eye condition that causes serious progressive nearsightedness at an young age, a new study has found.
The findings, made through a study of the condition called keratoconus, could help more people protect their vision if treated on time. Keratoconus makes the cornea weak, which leads it to become cone-shaped over time.
The study found that females, Asian-Americans and people with diabetes appear to have a lower risk of keratoconus. The researchers looked at data from health insurance claims — half of them from more than 16,000 people with confirmed keratoconus and half from an equal number of people with similar characteristics but no keratoconus. People with Down syndrome had six times higher chance of developing the disease than others.

Midlife crisis may be a myth
The 'midlife crisis' theory which predicts that happiness declines the most from the early 20s to middle age may be a myth, a new study suggests.
For half a century, the accepted research on happiness has shown our lives on a U-shaped curve, punctuated by a low point that we have come to know as the "mid-life crisis". Today, the "midlife crisis" is a generally accepted phenomenon, fodder for sitcoms and the subject of advertising propaganda the world over, researchers said. However, based on data drawn from two longitudinal studies, researchers from the University of Alberta in Canada challenge the existence of the theory.
Contrary to previous cross-sectional studies of life-span happiness, this new longitudinal data suggests happiness does not stall in midlife, but instead is part of an upward trajectory beginning in our teens and early twenties.
This study is far more reliable than the research that came before it, researchers said. "If you want to see how people change as they get older, you have to measure the same individuals over time," said Harvey Krahn from University of Alberta. The team followed two cohorts — one of Canadian high school seniors from ages 18-43 and the other a group of university seniors from ages 23-37. Both showed happiness increased into the 30s, with a slight downturn by age 43 in the high school sample.
After accounting for variations in participants' lives, such as changes in marital status and employment, both samples still demonstrated a general rise in happiness after high school.

Smoking a hookah is now the latest fad among Indian youngsters
A first of its kind data released on Wednesday has announced alarming findings - compared with a single cigarette, one hookah session delivers approximately 125 times the smoke, 25 times the tar, 2.5 times the nicotine and 10 times the carbon monoxide.
The research team reviewed 542 scientific articles to reach the finding.
A frequent cigarette smoker may smoke 20 cigarettes per day, while a frequent hookah smoker may only participate in a few hookah sessions each day.
The World Health Organisation says that since the release of the WHO advisory note on Waterpipe Tobacco Smoking in 2005, waterpipe research has received important attention, and resulted in new evidence.
Waterpipe use accounts for a significant and growing share of tobacco use globally. Its use is most prevalent in Asia, Africa and the Middle East, but it is a rapidly emerging problem in other continents such as Europe, North America and South America. Specifically, in the US, the decreasing prevalence of cigarette smoking as a result of decades of tobacco control efforts has coincided with the emergence of relatively unregulated cigarette alternatives such as smoking flavoured tobacco via waterpipe (hookah).
WHO confirms "A typical waterpipe tobacco smoking session may deliver over 20 times the smoke volume of a single cigarette".
The new meta-analysis led by the University of Pittsburgh School of Medicine confirms WHO's fears that hookah smokers are inhaling a large load of toxicants.
"Our results show that hookah tobacco smoking poses real health concerns and that it should be monitored more closely than it is currently," said lead author Brian A Primack, assistant vice chancellor for health.
These estimates come at an important time: the Centers for Disease Control and Prevention recently reported that, for the first time in history, past 30-day use of hookah tobacco was higher than past 30-day use of cigarettes among US high school students. Additionally, about one-third of US college students have smoked tobacco from a hookah, and many of those individuals were not previous users of other forms of tobacco.

E-cigarettes don't help smokers quit: Study
People who use electronic cigarettes, which are widely promoted and used to help smokers quit traditional cigarettes, are actually 28 per cent less likely to kick the butt, a new study has warned.
Electronic cigarettes, known by a variety of names including vapour pens, are battery-powered devices that heat nicotine and flavourings to deliver an aerosol inhaled by the user.
While they are promoted as a way to quit traditional cigarettes, they also are promoted as a way to get nicotine in environments where traditional cigarettes are prohibited.
Researchers at the University of California in San Francisco (UCSF) reviewed 38 studies assessing the association between e-cigarette use and cigarette cessation among adult smokers.
They then combined the results of the 20 studies that had control groups of smokers not using e-cigarettes in a meta-analysis that concluded that the odds of quitting smoking were 28 per cent lower in smokers who used e-cigarettes compared to those who did not.
The studies included smokers who both were and were not interested in quitting, and included people as young as 15 years old.
The studies included in the analysis controlled for many variables, including demographics, past attempts to quit, and level of nicotine dependence.
"The irony is that quitting smoking is one of the main reasons both adults and kids use e-cigarettes, but the overall effect is less, not more, quitting," said Stanton A Glantz from UCSF.
"While there is no question that a puff on an e-cigarette is less dangerous than a puff on a conventional cigarette, the most dangerous thing about e-cigarettes is that they keep people smoking conventional cigarettes," he added.
The findings were published in the journal The Lancet Respiratory Medicine.

‘Spermbots’ to aid fertility treatments
Scientists have developed motorised 'spermbots' by attaching tiny metal helices to sperm cells that can aid poor swimmers to reach an egg, an advance that could improve fertility treatments.
In the artificially motorised sperm cells, customised microhelices serve as motors for transporting sperm cells with motion deficiencies. "The metal-coated polymer microhelices are suitable due to potent, controllable, and non-harmful 3D motion behaviour," researchers said.
Researchers constructed tiny metal helices just large enough to fit around the tail of a sperm. Their movements can be controlled by a rotating magnetic field. Tests showed that the motors can be directed to slip around a sperm cell, drive it to an egg for potential fertilisation and then release it.
