An estimated 100,000 recreational scuba divers around the world have diabetes. But low glucose levels under water can lead to erroneous decisions or even unconsciousness. Given that scuba divers always have buddies, the risk extends to a second person as well.
Norway, Australia, New Zealand and a number of other countries prohibit diabetics from scuba diving, whereas Sweden, the UK and the United States restrict it.
A doctoral thesis by Peter Adolfsson, Senior Physician at the Queen Sylvia Children’s Hospital, at Sahlgrenska Academy presents a technique that may enable diabetics to scuba dive safely anywhere in the world.
A tiny needle is fastened a little more than one centimeter beneath the skin. A sensor at the top of the needle measures glucose values in the subcutaneous fat every tenth of a second, recording and transmitting the data to a monitor once every five minutes. If the values rise or fall by a certain percentage that has been adapted to the particular individual, the monitor sets off an alarm.
The needle remains in place for up to a week before it has to be changed. At that point it will have recorded glucose levels 2,016 times.
“A physically active diabetic is always at risk of developing high or low glucose levels,” Dr. Adolfsson says. “However, it is difficult, sometimes impossible, to monitor the levels during the course of an activity."
“This technique will enable some diabetics to scuba dive with tubes, and it can definitely offer support for type 1 diabetics who participate in football, floorball, cross-country skiing, golf and other sports.”
“Physical activity is important for everyone, and type-1 diabetics are no exception,” Dr. Adolfsson says. “My hope is that this technique will allow diabetics to scuba dive anywhere in the world, as well as to lead more active lives in other respects.”
Dr. Adolfsson, who was the official physician of the Swedish women’s national football team for nine years under Marika Domanski Lyfors, has participated in three European Championships, two World Championships and one Olympic. He defended his thesis, Recreational Scuba Diving and Type 1 Diabetes – Glucose Control during Physical Exercise, on September 14.Contact:

Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
