Swim centre personnel and lifeguards are trained in, and regularly practice, rescue from water and cardiopulmonary resuscitation, CPR. A study has been carried out with the aid of the Swedish Life Saving Association and Livräddarna Tylösand in order to describe the rescue process and how effectively lifeguards carry out CPR during a rescue from the sea. The study was recently presented by scientist and ambulance nurse Andreas Claesson of the Sahlgrenska Academy/University of Gothenburg at the "World Congress on Drowning Prevention" in Vietnam, 10-13 May.
The study involved 40 surf lifeguards, 26 men and 14 women, who participated in two tests. These were later compared with each other. On the first day, the participants carried out CPR for 10 minutes alone on a manikin. Various parameters were measured, including the depth and frequency of chest compression and the volume of ventilation. On the second day, the participants carried out a simulated surf rescue of an unconscious person of weight 80 kg, 100 metres from the shore with the aid of a special type of lifebuoy known as a "torpedo" buoy. The complete rescue procedure was recorded, and the lifeguard again carried out CPR for 10 minutes on a manikin on the beach.
"The most important finding was that the extreme exertion during the surf rescue did not affect the capacity of the lifeguards to carry out CPR. This was high during the complete procedure and was just as effective during the 10 minutes independently of whether the lifeguard had previously carried out exertion. The results are, of course, difficult to transfer to emergency healthcare, but the comparison is very interesting. We exchange the person carrying out chest compression every two minutes in order to ensure that the CPR is carried out in the best possible manner", says Andreas Claesson.
Andreas Claesson's previous studies of CPR have shown that it takes an average of 15 minutes from an alarm about drowning until arrival of an ambulance in Sweden.
"The first 15 minutes after a drowning accident are crucial. It is vital that someone at the scene calls an ambulance and immediately starts cardiopulmonary resuscitation without interruption, while waiting for the ambulance to arrive. Many precious minutes may be lost if the people at the scene are not trained in CPR, and this is not started until the ambulance arrives", says Andreas Claesson.He thinks that it should be taken for granted that lifeguards and swim centre personnel are present at beaches and in swimming halls, since studies have shown that the probability of surviving is much higher if these personnel are on site and can react immediately, while waiting for the ambulance.
"However, the situation in reality is different, and that's why I believe that all who want to and are able to should learn CPR and basic lifesaving skills, such that they can provide aid in the event of an emergency", says Andreas Claesson.Cardiopulmonary Resuscitation, CPR

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
