“A ‘smart’ insulin patch could replace painful injections to help millions of people with diabetes keep their blood sugar levels in check,” the Daily Mirror reports; though the technology has only been tested on mice.
Insulin is a hormone that plays a vital role in regulating blood glucose levels. People with type 1 diabetes, as well as advanced type 2 diabetes, require regular insulin injections, as their body either doesn’t produce enough insulin or reacts to it in the wrong way.
Researchers have developed a new type of glucose-sensing patch, which is worn on the skin and delivers insulin in response to sensing high levels of glucose.
The study showed that the patch was capable of reducing blood glucose levels to normal in mice with chemically induced diabetes over about four hours.
This research is at an early stage, so we therefore don’t know if it will be both safe and effective in humans. Before any human testing can occur, researchers will need to study the longer-term effects on animals. Researchers will also need to work out whether they can deliver enough insulin to regulate blood glucose levels in humans, and how often the patches need to be changed.
All in all, we wouldn’t expect to see these patches at your local chemist in the near future.
Is “Being a couch potato bad for your mental health,” the Mail Online reports. However, the evidence gathered by a new review is not as clear-cut as the headline would lead you to believe.
The review summarised the results of nine studies on the link between anxiety symptoms and sedentary behaviour, such as using a computer or watching TV.
Overall, five of the nine studies found a positive link – that as time spent sitting went up, so did the risk of anxiety symptoms.
However, the results of a review are only as reliable as the studies it includes, and in this case they weren’t very good. The majority of studies looked at sitting and anxiety at one time.
This can’t prove cause and effect, as we are faced with the classic “chicken and egg” dilemma: does sedentary behaviour cause anxiety symptoms, or are anxious people likely to spend more time sitting?
Importantly, we don’t know whether the studies took account of other factors that could be influencing the results, and most looked only at anxiety symptoms, not a diagnosis of anxiety.
Overall, this review doesn’t provide conclusive proof of a definitive link. The occasional boxset binge is probably not going to trigger general anxiety disorder by itself, but it is important to balance this out with regular exercise. Aside from the physical health benefits of exercise, it can also often reduce feelings of depression and anxiety.
Type 1 diabetes develops when the insulin-producing cells in the body have been destroyed and the body is unable to produce any insulin.
Insulin is the key that unlocks the door to the body’s cells. Once the door is unlocked glucose can enter the cells where it is used as fuel. In Type 1 diabetes the body is unable to produce any insulin so there is no key to unlock the door and the glucose builds up in the blood.
Nobody knows for sure why these insulin-producing cells have been destroyed but the most likely cause is the body having an abnormal reaction to the cells. This may be triggered by a virus or other infection. Type 1 diabetes can develop at any age but usually appears before the age of 40, and especially in childhood.
Type 1 diabetes accounts for between 5 and 15 per cent of all people with diabetes and is treated by daily insulin injections, a healthy diet and regular physical activity.
Type 2 diabetes develops when the body can still make some insulin, but not enough, or when the insulin that is produced does not work properly (known as insulin resistance).
Insulin acts as a key unlocking the cells, so if there is not enough insulin, or it is not working properly, the cells are only partially unlocked (or not at all) and glucose builds up in the blood.
Type 2 diabetes usually appears in people over the age of 40, though in South Asian and black people, who are at greater risk, it often appears from the age of 25. It is also increasingly becoming more common in children, adolescents and young people of all ethnicity.
Type 2 diabetes accounts for between 85 and 95 per cent of all people with diabetes and is treated with a healthy diet and increased physical activity. In addition to this, medication and/or insulin is often required.
There are many people who rely on mobility aids for their everyday activities. One of such main mobility product is wheelchairs. There are many types of wheel chairs like lightweight wheelchairs, transit wheelchairs, heavy duty wheelchairs and self propelled wheelchairs.
Self propelled wheelchairs are gaining importance these days as these wheelchairs have larger rear wheels to enable the occupant to propel themselves. The seats of these wheelchairs are made of vinyl which is very strong, thin and lightweight. Another benefit of Vinyl is that it is easy to clean and stains can be easily removed by wiping it with a warm wet cloth.
