New research has identified key genes that are linked to pain tolerance, which may explain why people perceive pain differently. Researchers evaluated 2,721 people diagnosed with chronicA disease of long duration generally involving slow changes. pain for certain genes. Participants were taking prescription opioid pain medications. The genes involved were COMT, DRD2, DRD1 and OPRK1. The participants also rated their perception of pain on a scale from zero to 10. People who rated their pain as zero were not included in the study.

Bacteria can survive longer in contact lens cleaning solution than previously thought

This causes inflammationThe body’s response to injury. and ulcerationThe presence or formation of an ulcer - an abnormal break in epithelium, the outer layer of cells covering the open surfaces of the body. of the corneaThe transparent, thin-walled dome that forms the front of the eyeball. that can lead to loss of vision. The use of contact lenses has previously been identified as a particular risk factor for the condition and new research has shown that a bacterial strain associated with more severe infections has enhanced resistanceThe ability of a microbe, such as a type of bacteria, to resist the effects of antibiotics or other drugs. to a common contact lens disinfectant solution.

Reduced salt intake linked to the fall in deaths from cardiovascular disease

The number of deaths from cardiovascular diseaseDisease of the heart and blood vessels, usually due to atherosclerosis. has fallen considerably in England over the last decade. A new study carried out by the Queen Mary University of London has now looked at whether this is linked toa reduction in average dietary salt intake during the same period. Between 2003 and 2011, average salt intake fell by 15% in England, and deaths from heart disease and strokeAny sudden neurological problem caused by a bleed or a clot in a blood vessel. fell by around 40%.

Optimistic outlook may reduce the risk of heart failure

A number of previous studies have suggested that taking an optimistic view on life may be beneficial to health and that a positive attitude may increase the life expectancy of heart disease patients. A new study has shown that high levels of optimism in older people may reduce the risk of heart failureFailure of the heart to pump adequately..

Two Minute Treatment Time for Lung Cancer

The latest stereotactic body radiotherapyThe treatment of disease using radiation. treatments (SBRT) for prostateA gland that surrounds the urethra near the bladder. It produces a fluid that forms part of the semen. and advanced lung cancerAbnormal, uncontrolled cell division resulting in a malignant tumour that may invade surrounding tissues or spread to distant parts of the body. are being delivered significantly faster than before thanks to the latest radiotherapy instrumentation. For lung SBRT, treatment delivery times are down to less than two minutes on average, which is good news for patients.

New agents may revitalise antibiotics to fight superbugs

Anew study suggests it may be possible to fight superbugs with conventional antibioticsMedication to treat infections caused by microbes (organisms that can't be seen with the naked eye), such as bacteria. by pairing them with a new class of metal-based agents called metallopolymers.

Scientists develop blood test to rapidly diagnose stroke

When someone suffers from a strokeAny sudden neurological problem caused by a bleed or a clot in a blood vessel. time is of the essence.

Living organ regenerated for first time

A team of scientists at the University of Edinburgh has succeeded in regenerating a living organ for the first time. The team rebuilt the thymus, an organ in the body located next to the heart that produces important immune cells.The advance could pave the way for new therapies for people with damaged immune systems and geneticRelating to the genes, the basic units of genetic material. conditions that affect thymus development.

Visualising a safe place reduces the pain of medical procedures

Visualising a safe place can reduce the pain and anxiety caused by invasive medical procedures, according to new research carried out at Copenhagen University Hospital, in Denmark.

Nurses guided patients into a trance and found it helped them to cope with pain and anxiety during ablation of atrial fibrillationA common abnormal heart rhythm causing a rapid, irregular pulse and failure of the upper chambers of the heart (atria) to pump properly. Abbreviated to AF. (AFAn abbreviation for atrial fibrillation).

Depression increases heart failure risk by 40 per cent

Moderate to severe depressionFeelings of sadness, hopelessness and a loss of interest in life, combined with a sense of reduced emotional well-being increases the risk of heart failureFailure of the heart to pump adequately. by 40%, a new study has shown.

Lise Tuset Gustad, first author of the study and an intensive care nurse at Levanger Hospital in Norway, said: "We found a dose response relationship between depressive symptoms and the risk of developing heart failure. That means that the more depressed you feel, the more you are at risk."
