20 Jul Death Rate From HIV-AIDS Continues to Drop
MedicalResearch.com Interview with:
Dr. Colette Smith: PhD
Research Department of Infection and Population Health
University College London, London, UK
Medical Research: What are the main findings of the study?
Dr. Smith: We followed a group of approximately 45,000 HIV-positive people from Europe, USA and Australia between 1999 to 2011. We found that the death rate approximately halved over the 12-year study period. For every 1,000 people, around 18 died per year in 1999-2001, reducing to 9 deaths per year in 2009-2011.
We also studied what people died of. We found that the death rate from AIDS and from liver disease decreased by around two-thirds. Deaths from heart disease approximately halved. However, the rate of cancer deaths (excluding cancers that are classified as AIDS events) remained constant over time.
One in three deaths were caused by AIDS in 1999 to 2011, and this decreased to one in five deaths in the last two years of the study. However, even in recent years it was the joint most common cause of death. The proportion of deaths from cancer increased over time. One in ten deaths were from cancer in 1999 to 2001, and this increased to one in five deaths in 2009 to 2011. By the end of the study it was the joint-most common cause of death.
10 Jul Childhood Tuberculosis Likely Under-diagnosed and Under-reported
MedicalResearch.com Interview with:
Pete Dodd (BA, BSc, MMath, PhD)
Research associate in health economic modelling
Health Economics and Decision Science
ScHARR
Regent Court Sheffield
Medical Research: What are the main findings of the study?
Dr. Dodd: We found that over 650,000 children under the age of 15 developed tuberculosis in the 22 highest burden countries in 2010, with around 7.6 million becoming infected with the bacillus and more than 50 million harboring latent infection.
Our work points to a much larger gap between notifications and incidence in children compared to adults.
03 Jul Nasal Cavity Malignancies: Charged Particle Therapy May Be Superior To Conventional Photon Therapy
MedicalResearch.com Interview with:
Dr. Robert Foote MD
Chair, Department of Radiation Oncology
Mayo Clinic, Rochester, MN
MedicalResearch: What are the main findings of the study?
Dr. Foote: Charged particle therapy (mainly protons and carbon ions) provide superior overall survival, disease-free survival and tumor control when compared to conventional photon therapy. In particular, it appears that proton beam therapy provides superior disease-free survival and tumor control when compared to the state of the art intensity modulated radiation therapy using photons.
03 Jul Accidents and Violence Account For Most Deaths Among US Young People
MedicalResearch.com Interview with:
Tamara Haegerich, PhD
Deputy Associate Director for Science
Division of Unintentional Injury Prevention
CDC - National Center for Injury Prevention and Control
MedicalResearch: What are the main findings of the study?
Dr. Haegerich: In the first three decades of life, more people in the US die from injuries and violence than from any other cause. Approximately 60% of fatal injuries are unintentional (for example, from motor vehicle crashes, drug overdose, and falls), 20% are due to suicide, and 20% are due to homicide. Injuries and violence have been linked to a wide range of physical, mental health, and reproductive health problems, and chronic diseases. They take an enormous economic toll, including the cost of medical care and lost productivity. Importantly, injuries and violence are preventable through education, behavior change, policy, engineering, and environmental supports. For example, laws that promote the use of seat belts and child safety seats, and prevent drunk driving, can reduce motor-vehicle-related injuries. Early childhood home visitation, school-based programs, and therapeutic foster care are examples of evidence-based approaches to preventing violence. Improving proper prescribing of painkillers and access to treatment for substance misuse could prevent prescription drug overdoses. Improvements are possible by framing injuries and violence as preventable, identifying interventions that are cost-effective and based on research, providing information to decision makers, and strengthening the capacity of the health care system.
03 Jul Insulin Pump May Be A Valuable Option For Difficult Type 2 Diabetes
MedicalResearch.com Interview with: Professor Yves Reznik Department of Endocrinology, University of Caen Côte de Nacre Regional Hospital Center Caen, France MedicalResearch: What are the main findings of the study? Prof. Reznik: OPT2MISE definitively demonstrate that pump therapy is a valuable option for treating those type 2 diabetes patients with uncontrolled hyperglycemia despite a high dose insulin regimen including at least 3 injections per day of rapid-acting and slow-acting insulin analogues, the gold standard for intensified insulin therapy. Such benefit on glucose control is obtained with lower daily insulin doses and without weight gain in comparison with multiple injection therapy. Pump therapy is effective in a population of patients un-preselected for their ability to deal with a medical device.01 Jul Slowdown In US Health Care Costs Largely Due to Flat Physician Reimbursement, Use of Generic Drugs
MedicalResearch.com Interview with: M Luca Lorenzoni OECD Organisation for Economic Co-operation and Development Health Accounts, Asian Health and Social Policy Outreach ELS/Health Division MedicalResearch: What are the main findings of the study? Answer:- The United States is an outlier in the scenery of OECD as it ranks first for health care expenditure, but last for coverage.
- The slowdown in US health care spending during the past decade brought the growth rate closer to that of other high-spending countries -Canada, France, Germany, the Netherlands and Switzerland- at around 1%. Previously in 2002, the US's health expenditure growth was around 7%, much higher than the approximate 3% which was the average for the other countries examined in the study
- Higher health-sector prices (e.g., hospital care and prescription drugs) are thought to be the main driver of expenditure differences between the US and other high-spending countries, and recent price dynamics largely explain declines in health expenditure growth.
26 Jun Adults with Asperger Syndrome May Experience Increase Risk of Suicidal Thoughts
MedicalResearch.com Interview with:
Dr Sarah Cassidy PhD
Autism Research Centre,Department of Psychiatry
University of Cambridge, Cambridge, UK
MedicalResearch.com: What are the main findings of the study?
Dr. Cassidy: We found that adults with late diagnosis of Asperger Syndrome (31 years on average), were at significantly higher risk of contemplating suicide during their lifetime (66%) than those from the general UK population (17%), and a sample of patients with Psychosis (59%).
We also found that adults diagnosed with Asperger Syndrome with a history of depression, were significantly more likely to experience suicidal thoughts, and suicide plans or attempts, than those with Asperger Syndrome without a history of depression. A higher level of autistic traits was also a significant risk factor for having planned or attempted suicide.
24 Jun Heart Attack Admissions In China Quadrupled Over 10 Years
MedicalResearch.com Interview with:
Professor Lixin Jiang MD, PhD, F.A.C.C.
National Clinical Research Center of Cardiovascular Diseases
State Key Laboratory of Cardiovascular Disease
Fuwai Hospital, National Center for Cardiovascular Diseases
Beijing , China
MedicalResearch: What are the main findings of the study?
Professor Jiang: In this first representative nationwide assessment of quality of care in China, we studied 13,815 hospital admissions for STEMI in 162 hospitals across China over the past decade. We found that the incidence of hospital admission for STEMI quadrupled from 3.7 per 100,000 in 2001 to 15.8 per 100,000 in 2011.
There were substantial changes in testing and treatment patterns. Over the study period, the rate of testing for troponin increased from 21.4% in 2001 to 66.5% in 2011. Additionally, based at the ideal patients’ analysis, the use of several highly effective treatments for STEMI, including aspirin, clopidogrel and statins, improved over the study period. However, other therapies known to reduce mortality in STEMI patients – such as β-blockers and ACE inhibitors – were underused with only 57.7% of patients receiving beta-blockers and 66.1% ACE inhibitors respectively in 2011.
While the proportion of patients receiving reperfusion therapy remained constant, there was a notable shift away from fibrinolysis, which was the primary means of reperfusion in 2001, towards primary PCI. However, in 2011, only 27.6% of patients admitted to Chinese hospitals for STEMI received primary PCI, the gold standard of treatment, while 27.4% received fibrinolytic therapy in the ideal patients.
Despite increasing overall intensity of treatment, procedure use, and testing, no significant change in the rate of in-hospital death from STEMI was seen over the study period.
18 Jun Patients With Mental Illness More Likely To Be Victims of Homicide
MedicalResearch.com Interview with:
Professor Louis Appleby
Professor of Psychiatry C.B.E
The University of Manchester in the UK
MedicalResearch: What are the main findings of the study?
Professor Appleby: “Patients with mental illness are two and a half times more likely to be victims of homicide than people in the general population according to our research published in The Lancet Psychiatry today.
“In this study, the National Confidential Inquiry into Suicide and Homicide by People with Mental Illness (NCI), based at The University of Manchester, examined data on the victims and perpetrators of all homicides in England and Wales between January, 2003 and December, 2005.
We found that during the 3-year study period, 1496 people were victims of homicide, and 6% (90) of them had been under the care of mental health services in the year before their death. A third (29) of these patient victims were killed by other patients with mental illness.
In 23 homicides in which the victim was a mental health patient killed by another mental health patient, the victim and the perpetrator were known to each other either as partners (9, 35%), family members (4, 15%), or acquaintances (10, 38%). In 21 of these 23 cases, both the victims and perpetrators were undergoing treatment at the same National Health Service Trust.
Alcohol and drug misuse (victims 66%, perpetrators 93%) and a history of violence (victims 24%, perpetrators 24%) were common among both patient victims and perpetrators. The study also found that in the 3 years to 2005, 213 mental health patients were convicted of homicide—accounting for 12% of all homicide convictions.”
11 Jun Parkinson’s Disease: Are Newer Meds Better Than Levodopa?
MedicalResearch Interview with:
Richard Gray
Professor of Medical Statistics
Clinical Trial Service Unit
Richard Doll Building, Oxford
MedicalResearch: What are the main findings of the study?
Prof. Gray: We found that, when we asked patients with Parkinson’s disease how their drugs affected their overall quality of life, the older drug levodopa was better than newer, more expensive drugs and that this benefit persisted for at least seven years from starting treatment.
03 Jun Benefits of Managing Mild Hypertension in Younger Patients
MedicalResearch.com Interview with: Eleni Rapsomaniki, PhD The Farr Institute of Health Informatics Research Department of Epidemiology & Public Health University College London London MedicalResearch: What are the main findings of the study? Dr. Rapsomaniki: Our data shows that hypertension is associated with considerable reduction in CVD-free life expectancy. Based on our estimates a 30-year old with hypertension suffered from CVD 5 years earlier compared to a similarly aged individual with normal blood pressure. We noted substantial heterogeneity in the associations of blood pressure with specific cardiovascular outcomes. For example a 20 mmHg increase in systolic blood pressure was associated with ~40% higher risk of stable angina, and intracerebral or subarachnoid haemorrhage but less than 10% increase in risk of abdominal aortic aneurysm. In all age groups from 30 to over 80 people with a systolic blood pressure 90–114 mm Hg and a diastolic blood pressure of 60–74 mm Hg had the lowest risk of all cardiovascular diseases, and we found no J-shape associations.01 Jun Two Billion People Overweight or Obese
MedicalResearch.com Interview with:
Rhonda Stewart
Senior Communications
Institute for Health Metrics and Evaluation
Seattle, WA 98121, USA
MedicalResearch: What are the main findings of the study?
Answer: Globally, obesity has become a public health epidemic. Obesity is affecting not just developed countries, but developing countries as well. Almost one-third of the world’s population, over 2 billion people, are considered to be overweight or obese. Of this group, nearly two-thirds (62%) are in developing countries. If current trends continue, this number will continue to rise. Between 1980 and 2013, the prevalence of overweight or obesity for children and adolescents increased by nearly 50%. This study is the first analysis of global trends on obesity and covers more than 30 years and 188 countries.
27 May How Best to Manage Co-Infection with Both TB and HIV?
MedicalResearch.com Interview with:
Dr. Duncan M. Chanda MD
Institute for Medical Research & Training and UNZA-UCLMS
Research and Training Project
University Teaching Hospital
Lusaka, Zambia
MedicalResearch: What are the main findings of the study?
Dr. Chanda: The main findings are that in this cohort of relatively healthy patients, with a median CD4 of 367, ART can be delayed till the end of TB short course chemotherapy without deleterious effects. This differs from studies that looked at cohorts with very low median CD4 ( around 25-150 in most cases) in which early cART was found to reduce mortality and other AIDS defining events.
20 May Antibiotics In Infancy and Childhood Asthma, Viral Infections
MedicalResearch.com Interview with:
Adnan Custovic DM MD PhD FRCP
Professor of Allergy
Institute of Inflammation and Repair
University of Manchester
University Hospital of South Manchester
Manchester M23 9LT, UK
MedicalResearch: What are the main findings of the study?
Dr. Custovic: In a longitudinal analysis of the data from our birth cohort study collected from birth to age eleven years, we demonstrated an association between early-life antibiotic prescription and development of wheezing, but not atopy. Furthermore, amongst children with wheezing, antibiotic prescription in infancy increases the risk of subsequent severe wheeze/asthma exacerbations and hospital admissions. This is the first demonstration that children who receive antibiotics in infancy have impaired antiviral immunity later in life, and that early-life antibiotic prescription is associated with variants on chromosome 17q21 locus (which is an asthma susceptibility locus).
Our findings suggest that the association between antibiotics and childhood asthma reported in previous studies arises through a complex confounding by indication, in which hidden factors which increase the likelihood of both antibiotic prescription in early life and subsequent asthma development are increased susceptibility to virus infections consequent to impaired antiviral immunity, and genetic variants on 17q21. Our results raises an important issue that effects which are often attributed to environmental exposures may be a reflection of genetic predisposition.
14 May Post Heart Attack: Insulin Based Diabetes Control and Improved Longevity
MedicalResearch.com Interview with: Viveca Ritsinger MD Karolinska Institute, Department of Medicine, Cardiology Unit, Karolinska University Hospital, Stockholm Unit for Research and Development Kronoberg County Council, Växjö, Sweden MedicalResearch: What are the main findings of the study? Dr. Ritsinger: This is a long-term follow-up of the Swedish DIGAMI 1 study where patients with acute myocardial infarction and diabetes were randomized to either intensified insulin-based glycaemic control or to standard glucose lowering treatment. Patients and controls were followed for mortality for over 20 years and 90% of the patients died during follow up. Survival improved during a period of about 8 years. Intensified insulin-based glycaemic control increased survival time by an average of 2.3 years.13 May Suicide A Risk Factor for Mental Health Issues, Suicide in Bereaved
MedicalResearch.com interview with:
Dr Alexandra Pitman MBBS MRC Psych
MRC Clinical Research Fellow,
UCL Division of Psychiatry, UCL (University College London
MedicalResearch: What are the main findings of the study?
Answer: We conducted a systematic review of all published research comparing the experience of suicide bereavement with bereavement due to other causes, in which we considered the evidence from 57 studies evaluating the effect of bereavement on death, mental health, and social functioning of family members, friends, and other close contacts of the deceased. These studies showed that parents and children bereaved by suicide were at higher risk of mental health problems after the loss than parents and children bereaved by other causes, and that spouses and mothers bereaved by suicide were at higher risk of suicide than spouses and mothers bereaved by other causes. We also found some evidence that people from a range of kinship groups bereaved by suicide report more rejection and shame than people bereaved by other violent deaths, and that feeling stigmatised by the death is commonly experienced after any violent bereavement. It seemed that people bereaved by violent deaths, for example due to accidental death, homicide, drug-related death, motor vehicle crash, undetermined death or suicide, shared a sense of feeling blamed for the death or tainted by their association with the deceased.
30 Apr Diabetes Remission After Lap-Band Surgery
MedicalResearch.com Interview with:
Prof. Paul E O'Brien
Centre for Obesity Research and Education
Monash University
Melbourne, Australia
MedicalResearch.com: What are the main findings of the study?
Prof. O'Brien: Using a randomised trial format we compared the diabetes status at two years after a program of multidisciplinary diabetes care (MDC) alone or with the addition of a Lap-Band procedure in 50 people who were overweight (BMI 25-30) and with diabetes. 52% of the Lap-Band group had remission of their diabetes as measured by glucose tolerance testing compared to 8% in the multidisciplinary diabetes care group. The Lap-Band procedures were performed as outpatients with a 2-3 hr length of stay. There were no perioperative adverse events. The surgical group had lost a mean of 11.5kg in weight. The incremental cost effectiveness ratio (ICER) for remission of diabetes was AUD $20,700.
23 Apr Vitamin D Did Not Alter Risk of Falls
MedicalResearch.com Interview with: Dr Mark Bolland, PhD Bone and Joint Research Group, Department of Medicine University of Auckland, Auckland, New Zealand MedicalResearch.com: What are the main findings of the study? Prof. Bolland: In a meta-analysis of 20 randomized clinical trials, there was no effect of vitamin D with or without calcium on falls. In a trial sequential analysis of these trials, the effect estimate for vitamin D with or without calcium on falls lay within the futility boundary, providing reliable evidence that vitamin D supplementation does not alter the relative risk of falls by ≥15% and suggesting that future trials that are similar in design to current trials are unlikely to change that conclusion.20 Apr Emotional Problems in Adolescents: Very Common, Most Brief
MedicalResearch.com Interview with:
Dr. George Patton
Department of Paediatrics, University of Melbourne
Centre for Adolescent Health, Murdoch Children's Research Institute,
Royal Children's Hospital, Parkville, VIC, Australia
MedicalResearch.com: What are the main findings of the study?
Dr. Patton: Although there has been wide acceptance that the teens are a time when emotional problems are common, views have been polarized about their significance. Some have viewed these problems are usual for this phase of life with little significance for later life mental health; others have argued that early psychiatric intervention was essential given the risks of ongoing disorders.
In this sample almost two thirds of girls and a third of boys had an episode of emotional troubles (anxiety and depression) at a level that would concern a family physician. For those where the episode were brief lasting weeks to months, recovery without further later life episodes was common. In contrast those with persistent (longer than 6 months) or recurrent emotional problems during the teens had a high likelihood of similar problems with depression and anxiety in their twenties. In general these emotional problems persisted more in females than in males.
17 Apr Recommendation Allows Mother To Hold Newborn Immediately After Birth
MedicalResearch.com Interview with: Nestor E. Vain M.D. Professor of Pediatrics, School of Medicine, University of Buenos Aires Vice-President, FUNDASAMIN (Foundation for Maternal Infant Health), Argentina Director, Neonatology, Hospital Sanatorio de la Trinidad Palermo and San Isidro, Buenos Aires MedicalResearch.com: What is the background of this study? Prof. Vain: Delayed umbilical cord clamping (DCC) is currently recommended by many professional associations. The main reason is that it decreases the incidence of iron deficiency in infancy, a very serious public health problem in developing countries, but also prevalent in the USA and in western Europe. Besides it has other advantages in premature infants such as better adaptation of the cardiovascular system to extra-uterine life. How does Delayed umbilical cord clamping work?. Approximately 30% of the fetal blood volume is in the placenta at the time of delivery. Waiting for a couple of minutes before clamping the cord allows for a large part of that blood volume to return to the infant. (this process is known as placental transfusion) Despite of these well known facts, and the absence of serious complications, the compliance with the recommendation of delayed umbilical cord clamping is low. Why is that? There may be a variety of reasons but we are certain that one very important one is that the majority of obstetricians and neonatologists believe that to achieve an efficient placental transfusion and to avoid a negative effect from gravity, it is necessary to hold the infant at or below the level of the vagina during those 2 minutes. In that way the procedure is cumbersome and it prolongs unwillingly a separation between the infant and the mother. The believe that the infant needs to be at that low level is based on small studies performed more than 35 years ago.13 Apr For Whiplash Treatment: Education and Advice As Good As Prolonged PT
MedicalResearch.com Interview with: Zoe Michaleff PhD Student, Musculoskeletal Division The George Institute for Global Health Sydney NSW 2000 Australia MedicalResearch.com: What are the main findings of the study? Answer: Our study showed that a 30 minute advice session with two phone call follow ups was as effective for chronic whiplash as the comprehensive physiotherapy exercise program in which participants received twenty, one-hour individually-tailored and supervised exercise sessions over a 12-week period. While people's pain and activity improved in both treatment groups, the most important finding is that there were no differences between groups. This finding held true for all outcome measures except for two secondary outcome measures of self rated recovery (global perceived effect) and functional ability (patient specific functional scale) which were in favour of the comprehensive exercise program however the size of these effects were too small to be considered clinically meaningful.09 Apr Aspirin Found Generally Not Effective in Reducing Pregnancy Loss
MedicalResearch.com Interview with:
Enrique F. Schisterman, Ph.D.
Chief and Senior Investigator
Epidemiology Branch, DIPHR
Eunice Kennedy Shriver National Institute of Child Health and Human Development Rockville, MD 20854
MedicalResearch.com: What are the main findings of the study?
Dr. Schisterman: Our results indicate that aspirin is not effective for reducing the chances of pregnancy loss in most cases. For the total number of women in the study, 13 percent of women who took aspirin and became pregnant subsequently experienced another loss, compared with 12 percent who took the placebo. Ultimately, 58 percent of women taking aspirin and 53 percent of the placebo group got pregnant and later gave birth.
However, additional research is needed to investigate the finding that women who had experienced a single, recent pregnancy loss (before 4 1/2 months of pregnancy and within the past year) had an increased rate of pregnancy and live birth while on aspirin therapy. Among this group, 78 percent of those who took aspirin became pregnant, compared with 66 percent of those who took the placebo. For this subset of women, 62 percent of the aspirin group and 53 percent of the placebo group gave birth.
04 Apr Lifestyle Interventions Reduced Risk of Diabetes, Cardiac Mortality
MedicalResearch.com Interview with:
Prof Guangwei Li MD
Department of Endocrinology
China-Japan Friendship Hospital
Center of Endocrinology and Cardiovascular Disease, National Center of Cardiology & Fuwai Hospital, Beijing, China
MedicalResearch.com: What are the main findings of the study?
Answer: Our study first shows that a six-year period of lifestyle intervention in Chinese people with IGT reduced the incidence of diabetes over a protracted time period and was ultimately associated with a significant reduction in total and cardio-vascular disease mortality. This reduction in mortality appears to be mediated in part by the delay in onset of diabetes resulting from the lifestyle interventions.
26 Mar Sleep Loss Associated with Obesity and Diabetes
MedicalResearch.com Interview with: Prof. Dr. Bernd Schultes Endocrinology and Diabetes Internal Medicine eSwiss Medical & Surgical Center Brauerstrasse 97 9016 St. Gallen Schweiz MedicalResearch.com: What are the main findings of the study? Professor Schultes: Sleep loss promotes the development of obesity and diabetes by metabolic and behavioral mechanism. MedicalResearch.com: Were any of the findings unexpected? Professor Schultes:...

Director of the Center for Health Outcomes and Policy Research
Center for Health Outcomes and Policy Research
University of Pennsylvania School of Nursing
MedicalResearch.com: Austerity measures and health-system redesign to minimise hospital expenditures risk adversely affecting patient outcomes. Against that backdrop, can you start by letting us know the background of the study?
Prof. Aiken: European Surgical Outcomes Study in 28 countries showed higher than necessary deaths after surgery.
A comparable study in the US showed that despite the nation spending hundreds of millions of dollars on improving patient safety, there were no improvements in adverse outcomes after surgery in US hospitals between 2000 and 2009. Clearly it is time to consider new solutions to improving hospital care for surgical patients, who make up a large proportion of all hospital admissions. Our study was designed to determine whether there are risks for patients of reducing hospital nurse staffing, and what, if any, are the benefits to patients of moving to a more educated nurse workforce.
21 Feb Promising Approach to Treat Non-Alcoholic Fatty Liver Disease and Visceral Obesity
MedicalResearch.com Interview with:
Norbert Stefan, MD
Heisenberg Professorship for Clinical and Experimental Diabetology
Department of Internal Medicine IV
University Hospital Tübingen
Tübingen, Germany
MedicalResearch.com: What are the main findings of the study?
Dr. Stefan: Currently there is little evidence for an effective and safe pharmacological treatment of nonalcoholic fatty liver disease (NAFLD). Based on the fact that inhibition of 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1), the enzyme, that converts inactive cortisone into active cortisol in metabolic tissues such as liver and adipose, was found to be effective to improve lipid metabolism in animals, we hypothesized that inhibition of 11β-HSD1 may also prove to be effective to decrease liver fat content in patients with NAFLD. In our 12 week trial in 82 patients with NAFLD, inhibition of 11β-HSD1 with RO5093151 resulted in a 14 % decrease of liver fat content and in a resolution of NAFLD in 20 % of the patients. This was accompanied by a decrease of liver enzymes. Furthermore, inhibition of 11β-HSD1 brought about a reduction of body weight and total body- and visceral adipose tissue mass, while insulin sensitivity did not change. In agreement with findings from other trials, also in our study 11β-HSD1 inhibition was well tolerated and safe.

MedicalResearch.com: Interview with:
Dr Heike Daldrup-Link
Associate Professor of Radiology
Stanford University School of Medicine, Palo Alto
MedicalResearch.com: What are the main findings of the study?
Answer: We use magnetic resonance imaging, a technology based on magnetic fields rather than radiotracers or x-rays. The underlying technology is not new – it has been used for tumor staging for many years. This is an advantage as MR scanners are available in nearly every major Children’s Hospital where children with cancer are treated. What is new about our approach is that we combined anatomical and functional images, similar to current approaches that use radiotracers and CT (PET/CT): We first acquired scans that showed the anatomy of the patient very well and we then acquired scans that depict tumors as bright spots with little or no background information. We did that by using an iron supplement as a contrast agent: The iron supplement can be detected by the MRI magnet and improved tumor detection and vessel delineation MR scans. We then fused the anatomical scans with the tumor scans.

MedicalResearch.com: What are the main findings of the study?
Answer: PANTHEON is the largest, evidence-based study of long-term treatment with N-acetylcysteine (NAC) in COPD patients conducted to date. The main finding of this study is that 1-year of treatment with high dose NAC (600mg twice daily) was effective at reducing exacerbations in patients with COPD, especially in the earlier stage [GOLD II (moderate) of disease. NAC was well tolerated.
