Diabetes patients denied vital prescriptions
Vital prescriptions for diabetes patients to manage their blood glucose are being refused by GPs, according to Diabetes UK. The Diabetes UK survey and prescription debates In a poll of 1,300 patients, researchers found that nearly half of those surveyed had been refused blood-testing strips, 39 per cent of which were type 1 patients. The issue of NHS resource management is divisive and difficult: the Department of Health has requested that GPs not restrict access to these prescriptions, citing clinical importance. Doctors insist that NHS resources need to be used as efficiently as possible. Type 1 diabetes patients need to take blood glucose readings in order to inject an appropriate amount of insulin in order to maintain good blood glucose control. While dietary control is an important part of managing type 2 diabetes, structured testing improves HbA1c levels, blood glucose control, and diabetes understanding, reducing the chances of long-term diabetic complications. The risks of poor blood glucose management Poor blood glucose management can, in the long term, lead to a number of serious complications. These include blindness, stroke, and amputation. Of course, the survey does not represent the entire diabetes population, but it does highlight some of the more problematic questions surrounding diabetes treatment. Implications for the NHS Barbara Young, Chief Executive of Diabetes UK, explained that the restrictions were motivated by a desire to save money: "But any short-term savings from doing this will be tiny compared to the long-term cost to the NHS of treating these complications. "We need to send an urgent message to NHS England that GPs restricting access to strips on cost grounds is wrong-headed, short-sighted, and unfair. It has to stop." Previous studies have demonstrated that when test strips are prescribed without accompanying education, HbA1c levels among people with type 2 diabetes have not improved. Because of this, some people are concerned that test strips are over-prescribed, but the issue is one of education: When test strips, along with an appropriate level of education, are provided to people who are actively testing, there have been significant positive changes. The survey In 2013, a survey of 20,000 people revealed that 48 per cent of respondents felt "some anxiety" or "strong anxiety" regarding the restriction of their test strips. There are a number of risks associated with restricted blood glucose testing. Type 1 patients may be: Unable to identify highs and lows adequately (increasing the risk of hyperglycemia and hypoglycemia) Worried about needing to ration test strips to last the month Unable to analyse results as well as they should Increased risk of hospital admissions due to high or low blood sugars, including diabetic comas While type 2 patients run the risk of: Being unable to understand which foods are appropriate for them Being unable to test for hypos, for patients on sulphonylureas, glinides, or insulin is firmly in favour of blood glucose testing, which is important for people with both types of diabetes. The patient autonomy required to manage diabetes makes test strip restrictions unworkable. There is no 'one size fits all' approach to blood testing: the individual needs of every patient must be taken into account.
Bad lifestyle choices in young people could lead to diabetes
New research has shown lifestyle choices of young people between 17 and 24 years of age can pose the risk of developing diabetes. This research was performed by the University of Veracruz (UV), in the east coast of Mexico, called the Lifestyles Nutrition Students and Risk of Type II Diabetes. Beatriz Torres Flores, PhD, and colleagues at the Centre for Research and Health Services at UV observed students’ habits for 25 years. Diabetes risk factors They reported that around 37 per cent of their participants were overweight or obese, and when combined with certain risk factors, this could lead to the development of diabetes. The risk factors included a lack of physical activity, skipping breakfast and psychological stress, which can develop from bad sleeping habits and tension. Missing breakfast led to metabolic stress among students, with specialists at the Mexican Diabetes Federation reporting this leads the body to believe no short-term food will be consumed, so it adapts to conserve energy and therefore weight is gained. UV specialists have developed programs of nutritional intervention and studied diabetes risk factors over the last 25 years, but more needs to be done according to Dr. Flores. "Although we know that there are people genetically predisposed to develop diseases such as diabetes, improving food culture as habits of the students is an option that would contribute to stopping the development of the disease," said Dr. Flores. "We find college students with glucose levels over 100 or blood pressure over 120, that clearly some of these cases represent a risk of developing a chronic degenerative disease".
Awareness concerns after diabetes-related amputations in Luton and Bedfordshire
A nationwide survey commissioned by Diabetes UK has found the majority of people are unaware that diabetes can cause amputations. This is despite the fact that 59 such amputations were recorded in Luton in the last three years, with 154 diabetes-related amputations occurring in Bedfordshire. Diabetes awareness November of each year is Diabetes Awareness Month, with World Diabetes Day held annually on November 14. However, Diabetes UK raised concerns that diabetes awareness is still unsatisfactory in certain areas following a nationwide survey of 1,986 people by Ipsos Mori. Less than half of people (43 per cent) were aware that diabetes could cause complications such as amputation, with 47 per cent and 45 per cent, respectively, unaware that diabetes can cause blindness or early death. Advertising campaign Diabetes UK has launched the findings as they start a regional advertising campaign in Bedfordshire and Luton, with the aim to raise awareness of type 2 diabetes. Lifestyle changes can prevent or delay up to 80 per cent of type 2 diabetes cases, but the charity is concerned people in Bedfordshire and Luton may not understand why. "The stark fact is that in the last three years 213 diabetes related amputations have happened in Bedfordshire and Luton yet our new research shows that public understanding of its consequences is much too low," Sharon Roberts Eastern Regional Manager of Diabetes UK, said. "It is vital that we raise awareness in Bedfordshire and Luton of the potential consequences of Type 2 diabetes, in particular, so that people understand that if they are carrying extra weight then it is really important that they take steps to lose it".
Liver responsible for regulating appetite, study suggests
A new study suggests that the liver is responsible for regulating appetite levels. This is the first time such a link has been discovered, and it could lead to effective treatment for obesity and type 2 diabetes. The research, published in Diabetes, found that mice with a high level of hepatic glucose in the liver didn't gain as much weight. Despite being given access to an appetising diet, the animals demonstrated a reduced appetite. Based on these results, researchers argue that stimulating the production of hepatic glycogen could treat type 2 diabetes and obesity by making it easier for people to control how much they eat. Joan J. Guinovart, lead author of the study at the Institute of Research in Biomedicine, said: "It is interesting to observe that what happens in the liver has direct effects on appetite. Here we reveal what occurs at the molecular level." The discovery was made by observing that the mice, in addition to having reduced appetites, showed few appetite-stimulating molecules in the brain. In fact, they had an increased number of appetite-suppressing molecules. Finally, the researchers discovered high levels of hepatic glycogen and high levels of appetite-suppressing molecules were linked to adenosine triphosphate (ATP), the molecule responsible for providing cells with energy. This is the molecule that is altered by diabetes and obesity. The link was described as a "perfect correlation." Although more research is needed, these promising results could form the basis for new treatments for type 2 diabetes and obesity.
Three in ten adults have undiagnosed diabetes
New research has suggested that three in ten adults with diabetes in the United States remain undiagnosed, revealing an urgent need for improvements in diabetes care. Undiagnosed diabetes The study, published in Annals of Internal Medicine, used the cascade of care method to show how many patients live with a condition compared to those being treated for it. Data was analysed from the National Health and Nutrition Examination Survey (NHANES) by researchers to create a cascade of care for diabetes. Over a five-year period, an estimated 28.4 million adults, or 11.8 per cent of the adult population aged 18 or older, were found to have diabetes. 7.9 million people are reportedly unaware of their diabetes, despite 85 per cent being linked to a care provider and 67 per cent visiting care providers at least twice the previous year. Diagnosis awareness To improve health outcomes, the authors suggested increasing awareness of diabetes diagnosis among patients is essential. The cascade of care concept, which is also used to implement gaps in care for HIV care, could be used similarly to assess gaps in healthcare where diabetes is not being diagnosed. Among the common undiagnosed symptoms of diabetes include fatigue and dizziness. If you believe you may be suffering from these symptoms, you should endeavour to see your healthcare professional as a matter of urgency.
Walnuts could increase insulin sensitivity and counter prostate cancer development
Including a high level of walnuts or walnut oil in your diet has a number of health benefits and reduces the risk of type 2 diabetes, new research suggests. The study, carried out by researchers at the University of California, and published in the Journal of Medicinal Food, found that walnuts slow the growth of prostate cancer, lower cholesterol, and increase insulin sensitivity. In addition, the walnut diet reduces levels of IGF-1, a hormone thought to increase the risk of prostate and breast cancer. Nutritionist and lead author Paul Davis said: "For years, the United States government has been on a crusade against fat, and I think it's been to our detriment. Walnuts are a perfect example. While they are high in fat, their fat does not drive prostate cancer growth. In fact, walnuts do just the opposite when fed to mice." Previous studies conducted by the researchers indicated that omega-3 fatty acids were responsible for these health benefits. However, this study suggests that omega-3 works in conjunction with other things found in walnut oil. A number of the health benefits identified by the study have the potential to benefit people with diabetes, especially type 2 diabetes. The increase in insulin sensitivity reduces the amount of insulin required to lower blood glucose levels, thus countering insulin resistance. Moreover, the study found that walnut oil reduces cholesterol. High cholesterol is linked to cardiovascular (heart) disease and stroke - two of the leading causes of death for people with diabetes - as well as increasing the incidence of long term diabetic complications.
Young motherless siblings save their dad from severe hypo
Six and eight year old sister and brother, Jonathon and Cheyenne Porter have received a bravery award for quick thinking that saved their dad from a potentially dangerous severe hypo. Jonathon and Cheyenne, from Queensland, Australia, have been looked after by their father, Glenn, since their mother sadly recently died from cancer. Whilst it is usually Glenn, who has type 1 diabetes, that looks after his children, the two youngsters returned the care when his blood glucose levels dropped very low, causing the father to have a seizure. Quick thinking The siblings acted quickly calling the emergency services and telling the operator that their dad was suffering a seizure as a result of a "serious low" and needed an ambulance. The operator figured that their father had diabetes and gave the children first aid instructions, including to lay Glenn on his side whilst the ambulance came to prevent choking. They saved my life It was important that Jonathon and Cheyenne acted so quick as Glenn slipped into a coma shortly after the call was made. Their father states that without his children, he may not have survived. When they picked up their award, presented to them by Queensland ambulance service, Jonathon and Cheyenne credited their mum with explaining what needed to be done if Glenn ever got into difficulty with his blood sugar levels. Glenn told Australia's Seven News: "Their mother would be very, very proud of them."
Clinical trials for Beta-O2 product aims to cure type 1 diabetes
The ΒAir bio-artificial pancreas, developed in Israel, is going into clinical trials to determine if it can find a cure for type 1 diabetes. Israel's Beta-O2 developed the implantable bio-artificial pancreas, which was recently implanted in the first of eight diabetes patients in Sweden. Islet cell encapsulation Islet cell encapsulation is being investigated as a cure for type 1 diabetes, however, immunosuppressant drugs must then be taken for the rest of their lives. To prevent this, Beta-O2's encapsulation technique protects the transplanted cells from destruction in the immune system, which characterises type 1 diabetes. Beta-O2's encapsulation has unique features that provide oxygen into these islet cells, which are "huge consumers of oxygen," said Dan Gelvan, Chairman of Beta-O2. "This company has taken an engineering approach to finding a way to make sure there is an active supply of oxygen to the transplanted cells," Gelvan added. Two-year pilot study This two-year pilot study is set to cost $1 million, enrolling eight participants and evaluating the safety, survival and function of the implanted Beta-O2 system. "Ours is a biological device that is meant to restore the original effect of having islet cells," Gelvan added. "You have all elements of a functioning pancreas in response to the body's varying glucose levels. We are actually simulating and emulating the functionality of an organ". When speaking about the device's lifespan, Gelvan said: "We don't know yet how long it lasts, but conventional islet transplants continue to function well for eight to nine years. We hope that because we've created a protected microenvironment fed by oxygen, it will last even longer".
New outpatient centre tackles diabetes in Leicester
An outpatient centre aimed at tackling diabetes has been opened in Leicester by diabetes campaigner and MP, Keith Vaz. The new department will be a renovated and refurbished ward of Leicester General Hospital, bringing together outpatients clinics held at Leicester Royal Infirmary and two General locations, including temporary buildings. "I am so pleased to see Leicester leading the way in tackling this condition," said Mr Vaz. "This unit will save lives. "By having dedicated diabetes services we can treat the condition more effectively and help people manage all aspects of their diabetes in one location". Specialist diabetes services The new centre aims to deliver specialist diabetes services to patients, with this one of a number of service moves that Leicester's Hospitals are set to commence. "There are 3.3 million people with diabetes in the UK and an estimated 50,000 in Leicester," said Mr Vaz. "As a diabetic, I and others will be very happy to have our care managed under one roof". The new department will unify services at the General and the Royal, according to Dr Ian Lawrence, head of service for diabetes at Leicester's Hospitals. "By offering a more cohesive service we look forward to offering our patients the best possible experience. "There is improved access compared to the Royal, which is beneficial for patients with foot problems, and we continue to provide comprehensive care for people with type 1 Diabetes".
Signs of diabetic retinopathy found in one in five patients
A new screening programme for diabetic retinopathy discovered that one in five diabetes patients had signs of the complication. The study, published in JAMA Ophthalmology and conducted by the University of Alabama at Birmingham, found that the problem was particularly prevalent in ethnic minorities. The authors claimed that the study illustrates the importance of diabetic retinopathy screenings. The authors stated that "The rate of self-reported dilated eye care use in the past year was low for the overall sample (32.2 per cent), suggesting that DR [diabetic retinopathy] screening in these settings could fulfil a critical role for patients with diabetes not routinely accessing annual dilated eye examination care." Diabetic retinopathy is caused by high blood glucose levels over an extended period of time weakening and damaging the small blood vessels within the retina. Although the study specifically addresses the issue in the United States, its findings have a global relevance. In England alone, 1,280 new cases of blindness caused by diabetic retinopathy are reported each year, according to the NHS, while a further 4,200 people are thought to be at risk of retinopathy-related vision loss. The NHS invites everyone with diabetes over the age of 11 to be screened for diabetic retinopathy once a year. The test consists of examining the back of the eyes and photographing the retina. It can detect diabetic retinopathy before the condition causes any changes to the patient's vision.
