Lying On your Back When Heavily Prenant Can Lead To Stillbirth

Scientists have alerted the public on one of the factors driving child mortality, saying, heavily pregnant women who sleep on their backs could be at higher risk of having a still birth. These findings are published in the ‘Journal of Physiology’.
The study found that lying on the back leads unborn babies to adopt a more dormant or inactive state, possibly caused by receiving lower levels of oxygen. According to the study, “These lower oxygen levels cause the foetus to move “to a low oxygen consuming state”, while the baby’s heart rate is also affected”.
Hence, the study found that this sleeping position puts more stress on the unborn baby, causing it to reduce its oxygen intake and shedding more light on why some babies are lost late on in pregnancy. Still birth is typically defined as foetal death at or after 20 to 28 weeks of pregnancy.
It results in a baby born without signs of life. It was reported that earlier studies have shown the position mothers lie in affects their baby’s health but did not reveal how or why.
However, reacting to this development, Lead researcher in the new study, Professor Peter Stone, of the University of Auckland, New Zealand, said: “Our controlled study found that lying on your back can add extra stress to the baby, contributing to the risk of still birth.”
He noted that the risk is likely to be increased further in women with underlying health conditions. For the latest research, scientists examined 29 healthy pregnant women in the third trimester (the last three months of the pregnancy) and their unborn children.
All the women were between 35 and 38 weeks pregnant and were at low risk of complications. Each woman was asked to lie in one of four positions – lying flat, lying on their back but propped up by 30 degrees and lying on the left or right side – in a randomly allocated order.
She remained in each position with one pillow under her head for 30 minutes while researchers monitored heart rates and the activity level of the foetus. Researchers found that when women lay flat on their backs, it caused physiological stress to the baby.
In response, it switched to a sleep-like state of lower activity where it consumed less oxygen. Its heart rate was also affected. Babies in the womb were five times more likely to be in this state when mothers were lying flat than when they were lying on their left.
The study’s authors said: “Maternal position has a significant relationship with both foetal behavioural state as determined by features of foetal heart rate and its variability.
The supine position (lying face up) maybe disadvantageous for foetal well being and in compromised pregnancies may be a sufficient stressor to contribute to foetal demise.” All the women involved in the study went on to give birth to healthy babies.
Stone added: “We have only looked at the effect of maternal positions for a short period of time while the mother is awake. Further research is needed to see the effect of staying in certain maternal sleeping positions overnight.’
In its reaction, the Royal College of Midwives said the research showed “position is important” for women in their third trimester. Louise Silverton, the RCM’s director for midwifery, said:
‘We have known for a long time that blood pressure is reduced where a woman is lying on her back. Many women will say that they don’t lie on their backs as they feel “funny” when they do.
Women are advised not to sleep on their backs. Also, it is known that, when in labour, moving a woman to her left hand side may improve the foetal heart rate What this study shows that is different is, that even in the healthiest of women with a foetus with no known risk factors, position is important.

High Fat Diets Injurious To Young Brains

A new scientific evidence has emerged to show that an excess of fatty foods could affect the brain development of the young, potentially leading to cognitive defects later in life.
These findings are published in the journal ‘Molecular Psychiatry’. Carried out by a team of researchers from ETH Zurich and the University of Zurich, Switzerland, the study looked at the difference in brains of young and adult mice who consumed either normal food or an extremely high-fat diet, which contained excessively high levels of saturated fats, commonly found in fast foods, charcuterie products, butter and coconut oil.
A low-carb diet means you eat fewer carbohydrates and a higher proportion of fat. This is often called a lowcarb, high-fat diet (LCHF). Most importantly, you minimise your intake of sugar and starches.
It was reported that after a period of just four weeks, the study team observed the first signs of cognitive impairment in the young mice fed the highfat diet, which could be seen even before the mice had started to gain weight.
The same changes in the behaviour of mature mice that had been fed a highfat diet over an extended period were not seen, although they suffered from other health problems as their metabolic systems were severely disrupted and they became obese.
However, Urs Meyer, one of the study’s authors, pointed out that, “this does not rule out the possibility that a high-fat diet may also be harmful for the brains of adult mice.”
A person’s age when the fatty foods are consumed is particularly important as high-fat foods tend to have an even stronger negative impact on the maturation of the prefrontal cortex during the period of late childhood to early adulthood.
This part of the brain takes longer to mature than others, leaving it more vulnerable to negative environmental experiences such as stress, infections and trauma, and as seen in the study, possibly a poor diet.
As it is responsible for the executive functions of the human brain including memory, planning, attention, impulse control and social behaviour, if it not functioning correctly or damaged in any way, it can lead to cognitive deficits and personality changes such as a loss of inhibitions, aggressiveness, or childish or compulsive behaviour.

AIDS: Older Men Now At Risk Of Drug Resistance

The United Nations has issued a report revealing that older persons on AIDS treatment are developing resistance and requiring treatment for other illnesses such as tuberculosis, TB, and hepatitis.
This development was contained in a new report issued by UNAIDS yesterday, as part of activities to mark the 2016 World AIDS Day. Although, more than 18 million people now have access to life-saving AIDS treatment, 1.2 million more than at the end of last year, the UNAIDS stated: “As people with HIV grow older, they are at risk of developing longterm side-effects from HIV treatment, developing drug resistance and requiring treatment for other illnesses such as tuberculosis and Hepatitis C."
In the report on the AIDS pandemic, which has infected 78 million people and killed 35 million since it began in the 1980s, UNAIDS said the consistently strong scale-up of treatment has seen annual AIDS-related deaths drop by 45 per cent to 1.1 million in 2015 from a peak of about two million in 2005.
The report also cited data from South Africa showing that young women who become infected with HIV often catch the virus from older men. However, it said prevention was vital to ending the epidemic in young women and the cycle of HIV infection needs to be broken.
Reacting to the development, Executive Director of UNAIDS, Michel Sidibe said: “Young women are facing a triple threat. They  are at high risk of HIV infection, have low rates of HIV testing, and have poor adherence to treatment.” But, as more HIV-positive people live longer, the challenges of caring for them as they get older, of preventing the virus spreading and of reducing new infections are tough, UNAIDS said, even though drugs can reduce virus levels in a patient’s blood to near zero and significantly reduce the risk of passing it on.
“The progress we have made is remarkable, particularly around treatment, but it is also incredibly fragile,” said Sidibe.
With detailed data showing some of the many complexities of the HIV epidemic, the report found that people are particularly vulnerable to HIV at certain points in their lives. It called for “life-cycle” approach to offer help and prevention measures for everyone at every stage of life.
In 2015, there were 5.8 million people aged over 50 living with HIV – more than ever before. UNAIDS said that if treatment targets are reached – the U.N. is aiming to have 30 million HIV positive people on treatment by 2020 – that number will soar.

Why Men Die Earlier Than Women

An insight has been given as to why men die earlier than women. In their efforts to boost the life expectancy of men, scientists have found that working long hours and reducing hours of sleep in midlife may lead to poorer physical health in old age. This is the findings of a new study published in the journal ‘Age and Ageing’.
The quarter-century study of Finnish businessmen found those who worked more than 50 hours a week and slept less than 47 hours weekly when they were middle aged were in worse physical health as old men than peers who had healthier work and sleep habits when they were in their prime.
Reacting to the study, Lead Author, Mikaela Birgitta von Bonsdorff of the University of Jyvaskyla in Finland, said: “The results are in line with what we hypothesised but we were not sure if we would be able to detect these longterm associations."
The ‘NewsmaxHealth’ reported that the researchers used data from the Helsinki Businessmen Study to follow the health outcomes for more than 3,000 white men born between 1919 and 1934.
About 1,500 of the men had provided clinical characteristics of health, self-rated health, working hours and sleep duration in 1974 when they were in their mid to late 40s, on average, and completed health related quality of life surveys in the year 2000, when most were in their 60s and 70s.
During their working years, nearly half of the original group of men had what researchers considered normal working hours of less than 50 hours per week and 352 men worked more than 50 hours a week.
Similar proportions of men had normal sleep of at least 47 hours per week, versus shorter sleep totals. Researchers found that men with long work and short sleep or long work and normal sleep in midlife had poorer scores for physical functioning, vitality and general health than those with normal work and normal sleep.
Midlife smoking and self-rated poor health at that time explained some of the association with the results at older age, but not all.

How To Manage Blood Pressure Naturally

Worried at the high burden of High blood pressure, which affected more than one billion people worldwide in 2015, scientists have alerted the public on natural methods of tackling the condition.
Managing this condition naturally has become necessary considering the fact that high blood pressure is a silent killer. Many people don’t realize they have it until it’s too late. High blood pressure (HBP or hypertension) is when your blood pressure, the force of the blood flowing through your blood vessels, is consistently too high. A heart attack brought on by high blood pressure can occur without any warning signs or symptoms.
That’s why it’s important to learn about natural ways to lower blood pressure. According to a new study published in ‘The Lancet’, in a healthy person, blood pressure can rise and fall throughout the day. When blood pressure stays high for a long period of time, this leads to an increased risk of heart disease, stroke and heart attacks.
Majit Ezzati, a professor of global environmental health at Imperial College London, who led the analysis, said globally, blood pressure is a condition of poverty, not affluence.
Besides, in the high-income world blood pressure rates were coming down despite the ageing and increasing population, Ezzati said, adding, in the population in Asia, as the age goes up, the blood pressure tends to be higher.”
Among natural methods recommended to lower high blood pressure are: get moving; reducing salt intake; and adopting a diet that include more fruits and vegetables. Many of those who suffer from high blood pressure turn to medication, but this is simply an approach that doesn’t address the root of the problem.
“A much healthier alternative is to use diet and exercise to maintain normal blood pressure levels,” the study shows. Consistent exercise strengthens the heart and enables it to pump more blood with less effort.
When the heart works less, the pressure on the arteries decreases and blood pressure is lowered. It could take up to a few months of consistent exercise to bring blood pressure down to healthy levels.
However, you have got to keep exercising several days a week or blood pressure levels can shoot right back up. Exercise brings with it another perk that helps maintain a healthy heart and lower blood pressure — getting rid of excess weight. But just because you’re exercising doesn’t mean you can eat anything you want and not suffer the consequences.
A hearthealthy diet is just as important as exercise to avoid the dangers of high blood pressure.

GMO Foods: Nigeria Academy Of Science Gives Endorsement Amidst Uncertainty

The Nigerian Academy of Science (NAS) has declared that genetically-modified foods are safe for consumption for now.This was against the warning by the National Biosafety Management Agency (NBMA) to the public to be wary of the products that are on sale in some stores. It said none of the products had been approved for local consumption. NAS, during a media roundtable on GMOs in Nigeria at its office in Lagos, said the country was ready for the products and that they were safe for both production and beneficial to the nation based on carefully-documented evidence from developed countries.
The academy noted that the technology, though new with expected fears and concerns, would be useful to the country because of its potential to boost the nation’s agriculture, which would resolve food insecurity.
The outgoing president of NAS, Prof. Oyewale Tomori, said though the technology seems fresh, but nothing is new with it, as the academy, in accordance with its mandate, has examined available evidence from researches in advanced countries.
According to him, the academy’s stance was informed by existing evidence from the industrialised countries, which have carefully followed laid-down principles for such activities, “but in Nigeria, the system has just been put in place, and we need to prepare for the future.”
Tomori, who noted that there were no forecasts of long-term effect, stressed: “We cannot predict the future and what is going to happen with these GMOs, but so far so good, there are no problem from where they have been used; but that does not mean that it is going to be good forever. We must be on the alert to know when changes are coming up.”
Besides, a professor of plant breeding and crop biotechnology with the Department of Genetic and Biotechnology, University of Calabar, Effiom Ene-Obong, who said there were no scientific evidence that agree with the raised health concerns of GMOs worldwide, “as they are safe for both production and consumption.”
He noted that though genetically-modified foods are not commercially produced in Nigeria yet, three quarters of countries in the world are keyed into them and as a new technology, fears being entertained are expected, “but rather the benefits outweigh the worries”
Ene-Obong added: “Before these products are sent into the market, lots of trials and investigations are done by so many agencies, such as the Academy of Sciences Worldwide, United Nations Educational, Scientific and Cultural Organisation (UNESCO), World Health Organisation (WHO), to monitor and make sure they are safe for human consumption and they have recommended.”
