Revolutionary Tool to Smell Prostate Cancer in Urine Samples

UK researchers tested a revolutionary tool to smell prostate cancer in urine samples during a small scale trial. The research team at the University of Liverpool conducted the trial in collaboration with researchers from the UWE Bristol.

UK researchers tested a revolutionary tool to smell prostate cancer in urine samples during a small scale trial. The research team at the University of Liverpool conducted the trial in collaboration with researchers from the UWE Bristol.

According to the joint press release, the trial results indicate a milestone in detecting prostate cancer using urine samples. If the revolutionary tool is successful in a large clinical trial, this could mean the end for invasive procedures men are currently undergoing for prostate cancer to be detected.

Current procedures to detect prostate cancer aren’t only invasive, but also rather inefficient. Some are inconclusive and some are too lengthy to enable early detection and prevention strategies. However, a revolutionary tool to smell prostate cancer in urine samples may change the status-quo.

The research team used gas chromatography (GC), a sensor system integrated in the Odoreader system developed in 2009 at UWE Bristol. The gas chromatography sensory system was used in addition to statistical data collected during previous studies. The results of the project are published in the Journal of Breath Research.

What the Odoreader sensor system does is ‘smell’ prostate cancer in urine samples. The system reads patterns and indicators, computing all available data to suggest the presence of certain indicators of prostate cancer based on urine samples.

The trial was conducted with the help of 155 men who sought the advice of UK urology clinics. Following tests, 58 men were diagnosed with prostate cancer. Another 24 men were diagnosed with bladder cancer. 73 men weren’t diagnosed with cancer but were found to have haematuria.

Urine samples collected from the 155 patients were run through the Odoreader sensor system. The urine samples were analyzed using algorithms set in place by the joint research team. The GC sensor system successfully identified volatile compounds present in different combinations. The process led to the detection of urological cancers based on urine samples collected from the men.

Provided the results are replicated in a larger clinical trial, the Odoreader sensor system enriched with the algorithms developed by the research team could become a key tool in early detection of prostate cancer and other urological cancers.

Further testing using urine samples is certainly a necessary step. Afterwards, the GC sensor system can efficiently be shifted to a user friendly format and made widely available. The researchers hope that the a revolutionary tool to smell prostate cancer in urine samples could be installed anywhere for easy, inexpensive access.

Wearable Device Will Check Your Health By Analyzing Your Sweat

January 28, 2016 By Tom Hager Leave a Comment

If you want an accurate analysis of your health, get ready to sweat.

If you felt like that just monitoring your heart rate or number of steps taken is not enough, a new wearable device will check your health by analyzing your sweat. Unfortunately, this device is still in its prototype stages of development, being created at the University of California, Berkely.

The main idea behind this device’s creation was to effectively attach a small pathology lab to each individual in order to check on a person’s biochemical levels which in turn point out to the onset of various illnesses or phenomena. Even if the device is long ways off until it can reach full viability in order for it to be commercialized, the first steps towards achieving that goal have already been taken.

At this point, the wearable band is flexible enough to be worn on your wrist, it can easily connect through Bluetooth to your smartphone and can accurately check on four distinct biomarkers. These chemical compounds are two electrolytes, sodium and potassium, and two metabolites, glucose and lactates.

In terms of sodium levels, can effectively signal an onset of dehydration or the threat of muscle cramps. By displaying a message to the user, it can advise you to drink an electrolyte-boosting drink or just take a small rest. Glucose levels in sweat are directly linked to the levels within the whole subject’s system, Regarding high levels of lactates, they can hint at low levels of blood pressure in specific parts of the body, depending on where the device is worn.

These four markers are just the start, with the research team focusing on the development of accurate protein and molecules in order to portray a more conclusive assessment of one’s health. Even if sweat has been partially ignored up to this point, with doctors focusing more on blood, urine, and saliva samples in order to discern a subject’s general well-being at a specific moment in time, it can effectively hint at various disease and illness onsets.

Even if at first, this device might seem to require large amounts of sweat in order to function properly, this is entirely not the case. The wearable can display an accurate analysis by just using one tenth of a sweat droplet. The developers of the device hope to reduce this amount even more in the future in order to dismiss the need of the wearer to undergo thorough exercise so that the device will function to its full extent.

Bearing in mind that the concept that a new wearable device will check your health by analyzing your sweat, major companies might approach this idea rather seriously if the prototype stage of the device proves to be extensively viable. The new age of wearable devices might be just around the corner.
