Researchers have developed a drug delivery technique for diabetes treatment in which a sponge-like material surrounds an insulin core. The sponge expands and contracts in response to blood sugar levels to release insulin as needed. The technique could also be used for targeted drug delivery to cancer cells.
In just four months, Singapore will once again play host to MEDICAL FAIR ASIA, as it makes a much anticipated return on 9 to 11 September 2014 at Suntec Singapore. The 10th edition of the international exhibition on Hospital, Diagnostic, Pharmaceutical, Medical & Rehabilitation Equipment & Supplies continues its tradition of show-on-show growth, with an expected 25% increase in exhibitors from its 2012 edition.
Extremely positive exhibitor response has resulted in a marked increase in space bookings received, which sees the show expand across two exhibition levels to meet the growing demand for floor space. Further driving this growth is the strong support received in the international arena, with new and returning nations Italy, Spain, Hungary, Turkey and The Netherlands showing keen interest in joining a broad line-up of country pavilions which already include Germany, Austria, France, UK, USA, China, Taiwan, Singapore, Korea, Japan and Malaysia.
Organized by Messe Dusseldorf Asia, Medical Fair Asia brings
together all facets of the medical and healthcare industry for networking, sharing of best industry practices, as well as product, service and solutions development. Part of MEDICA
Experts from the Too Fit to Fracture Initiative presented the results of an international consensus process to establish exercise recommendations for people with osteoporosis, with or without spine fractures. The results were presented at the World Congress on Osteoporosis, Osteoarthritis and Musculoskeletal Diseases in Seville, Spain.
Using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) method, the international multidisciplinary panel examined literature on exercise effects on: 1) falls, fractures, BMD, and adverse events for individuals with osteoporosis or spine fractures; and 2) pain, quality of life, and physical function after spine fracture. Evidence was rated as high, moderate, low, or very low.
In addition, a consensus process was used to established recommendations on assessment, exercise, and physical activity in the context of three cases with varying risk – one having osteoporosis based on bone density; one having osteoporosis and 1 spine fracture; and one having osteoporosis and multiple spine fractures, hyperkyphosis and pain.
The panel recommends that all individuals with osteoporosis should engage in a multicomponent exercise programme that includes resistance and balance training; they should not engage in aerobic training to the exclusion of resistance or balance training.
Other key points included:
current national physical activity guidelines are appropriate for individuals with osteoporosis in the absence of spine fracture, but not for those with spine fracture;
after spine fracture, aerobic activity of moderate intensity is preferred to vigorous; physical therapy consultation is recommended;
daily balance training and endurance training for spinal extensor muscles are recommended for all individuals with osteoporosis;
restrictions are a disincentive to activity participation, and for people with osteoporosis but no history of spine fracture, desired activities should be encouraged if they can be performed safely or modified;
health care providers should provide guidance on safe movement, rather than providing generic restrictions (e.g., lifting);
physical or occupational therapist consult is recommended for advice on exercise and physical activity among those with a history of spine fracture, particularly in the presence of balance or posture impairments, pain, comorbid conditions or that increase the risk of adverse events with exercise or activity, or unsafe movement patterns.
Lead author Dr Lora Giangregorio, University of Waterloo, Waterloo, Canada, stated, ‘People with osteoporosis and spinal fractures should be encouraged to participate in resistance training and balance training, as the strongest evidence we have supports multimodal exercise programs. We have developed evidence-based recommendations, as well as a report that addresses the ‘frequently asked questions’ of patients and health care providers around physical activity. We hope that the recommendations are helpful to health professionals worldwide as they guide their osteoporosis patients in safe, effective – and enjoyable – exercise regimens.’ International Osteoporosis Foundation
At least 30 percent of patients in intensive care units (ICUs) suffer some form of mental dysfunction as reflected in anxiety, depression, and especially delirium. In mechanically-ventilated ICU patients, the incidence of delirium is particularly high, about 80 percent, and may be due in part to damage in the hippocampus, though how ventilation is increasing the risk of damage and mental impairment has remained elusive. A new study found a molecular mechanism that may explain the connection between mechanical ventilation and hippocampal damage in ICU patients.

New research from Finland suggests in the not-too-distant future we may be making rapid, early diagnoses of prostate cancer using a non-invasive electronic nose that sniffs a urine sample.
Researchers from the University of Tampere describe how the ‘eNose’ successfully differentiated between prostate cancer and benign prostatic hyperplasia (BPH) by analysing the ‘smell print’ of the headspace of a urine sample (the air immediately above the urine).
The team says the results from the eNose are comparable to those obtained from prostate specific antigen (PSA) tests.
Prostate cancer is the second most common cancer in men and one of the leading causes of death from cancer. It is not easy to diagnose and make reliable prognoses about prostate cancer because it does not appear consistently in prostate tissue.
Currently, doctors rely on the digital rectal exam (DRE) and the PSA test to help decide if a biopsy is necessary. But these can be hit and miss, while biopsies are costly and uncomfortable, and carry the risk of infection. The other problem with current methods is that many diagnosed prostate cancers will not become life-threatening, and aggressive treatment risks reducing quality of life without extending it.
Odour sampling begins to show promise as a diagnostic for cancer
There have been experiments to test dogs’ ability to sniff out cancer, but scientists have noticed a lot of variation in their performance between and during studies.
About 20 or so years ago, researchers became interested in reports that dogs were detecting cancer in their owners, and since then there have been experiments to test dogs’ ability to sniff out cancer.
For example, in 2010, a scientific meeting of the American Urological Association learned how researchers in Paris had trained dogs to sniff out prostate cancer. They showed the dogs could detect certain prostate cancer cell-derived volatile organic compounds (VOCs) in urine.
However, as more research has been done using dogs, so scientists have noticed a lot of variation in their performance between and during studies, so their findings have limited application.
A more promising avenue is the growth of labs working on the electronic equivalent of sniffer dogs – artificial olfaction or electronic nose technology. For instance, in 2012 we were taken behind the scenes of an electronic nose lab at the California Institute of Technology, and learned how investigators in that lab foresee that one day we will be using smartphones to sniff out diseases.
Electronic noses or ‘eNoses’ that analyse complex mixtures of gas molecules are already used in food and agriculture quality control, and in military applications.
Exhaled air is a ‘problematic sampling material’
eNoses are already being investigated for medical use, including early detection of cancer from exhaled air, says lead investigator Dr. Niku Oksala, of the Department of Surgery in the School of Medicine at the University.
‘However, exhaled air is a problematic sample material since it requires good cooperation and technique from the patient and immediate analysis,’ notes Dr. Oksala, who is also of the Department of Vascular Surgery, Tampere University Hospital.
He points out that urine, on the other hand, is simple to obtain and easy to store, and more feasible for use in clinical practice. Plus, he says:
‘Preliminary data suggested that detection of urologic malignancies from urine headspace was possible. Our own preliminary results on prostate cancer cells encouraged us to launch this prospective clinical study.’

Plasma medicine is a new and rapidly developing area of medical technology. Specifically, understanding the interaction of so-called atmospheric pressure plasma jets with biological tissues could help to use them in medical practice. Under the supervision of Sylwia Ptasinska from the University of Notre Dame, in Indiana, USA, Xu Han and colleagues conducted a quantitative and qualitative study of the different types of DNA damage induced by atmospheric pressure plasma exposure. This approach, they hope, could ultimately lead to devising alternative tools for cancer therapy as well as applications in hospital hygiene, dental care, skin diseases, antifungal care, chronic wounds and cosmetics treatments.
To investigate the DNA damage from the so-called non-thermal Atmospheric Pressure Plasma Jet (APPJ), the team adopted a common technique used in biochemistry, called agarose gel electrophoresis. They studied the nature and level of DNA damage by plasma species, so-called reactive radicals, under two different conditions of the helium plasma source with different parameters of electric pulses.
They also identified the effect of water on DNA damage. To do so, they examined the role of reactive radicals involved in DNA damage processes occurring in an aqueous environment. They then compared them to previous results obtained in dry DNA samples.
The next step would involve investigating plasma made from helium mixtures with different molecular ratios of other gases, such as oxygen, nitrous oxide, carbon dioxide and steam, under different plasma source conditions. The addition of another gas is expected to increase the level of radical species, such as reactive oxygen species and reactive nitrogen species, known to produce severe DNA damage. These could, ultimately, help to destroy cancerous tumour cells.

A first-ever study from a large Canadian centre found that kidney transplant recipients lived longer and had better treatment success than patients on intensive home haemodialysis, but also had an increased risk of being hospitalised within the first year.
These findings were reported in a study entitled, ‘Survival and hospitalization for intensive home hemodialysis and kidney transplantation’, by lead author Dr. Karthik Tennankore, nephrologist at Dalhousie University, and Drs. Chris Chan and Joseph Kim, nephrologists at Toronto General Hospital, University Health Network.
The research reaffirms the need to encourage patients receiving intensive home haemodialysis to pursue kidney transplantation as a definitive treatment option for end-stage kidney disease. However, the study also found that the outcomes for these specific dialysis patients were generally positive, especially when compared to patients on in-centre haemodialysis (intensive home haemodialysis patient survival was 94% and 80% at one and five years).
‘For patients with end-stage kidney disease, a kidney transplant is still the best treatment option,’ says Dr. Chris Chan, Deputy Director, Division of Nephrology, University Health Network, R. Fraser Elliott Chair in Home Dialysis and Associate Professor of Medicine, University of Toronto. ‘But not everyone is a candidate for a transplant and we are facing a shortage of organs for these patients. We must continue to study and develop new and better ways to bridge the gap, and that includes developing better dialysis treatments.’
Dialysis will continue to be an important treatment option for many patients, points out Dr. Karthik Tennankore, Division of Nephrology, Dalhousie University. ‘This study also tells us that patients who are receiving this type of dialysis still have very good health outcomes.’
