Author Interviews, Cancer Research, Lancet, Thromboembolism / 08.10.2014

MedicalResearch.com Interview with: Prof Martin H Prins MD Maastricht University Medical Centre, Maastricht, Netherlands Medical Research: What are the main findings of the study? Dr. Prins: Patients with active cancer, i.e. a cancer that was diagnosed or treated within 6 months before the episode, that was recurrent or metastatic, or that was diagnosed during treatment, who had a symptomatic episode of venous thromboembolism, were included in this pooled subgroup analysis of the Einstein DVT and PE studies. The incidence of recurrent venous thromboembolism was similar between groups. It occurred in 16 (5%) of 354 patients allocated to rivaroxaban and 20 (7%) of 301 patients allocated to enoxaparin and vitamin K antagonist (hazard ratio [HR] 0•67, 95% CI 0•35 to 1•30). Clinically relevant bleeding was also similar and occurred in 48 (14%) of 353 patients receiving rivaroxaban and in 49 (16%) of 298 patients receiving standard therapy (HR 0•80, 95% CI 0•54 to1•20). However, major bleeding was less frequent among rivaroxaban recipients and occurred in eight (2%) of 353 patients receiving rivaroxaban and in 15 (5%) of 298 patients receiving standard therapy (HR 0•42, 95% CI 0•18 to 0•99). Mortality was also similar. (more…)
Author Interviews, Heart Disease, Hepatitis - Liver Disease / 08.10.2014

MedicalResearch.com Interview with: Naga Pothineni, MD Division of Cardiology University of Arkansas for Medical Science MedicalResearch: What are the main findings of the study? Dr. Pothineni: Hepatitis C is a blood borne infection that is very common worldwide. Most pateints who contract hepatitis C develop a chronic form on infection that progresses to liver damage and eventually hepatocellular cancer. Coronary heart disease is a worldwide problem as well. There has been interest in chronic infections being a mechanism of progression of atherosclerosis and coronary heart disease. We wanted to study the association of coronary heart disease events in patients with hepatitis C. We conducted a retrospective study of around 24,000 patients of which around 10,000 were hepatitis C positive. Our study showed that patients who have hepatitis C have a higher incidence of coronary heart disease events (myocardial infarction) when compared to patients who are negative for hepatitis C. In our analysis, we found that hepatitis C positivity is an independent risk factor for coronary events after adjusting for traditional cardiovascular risk factors like age, hypertension, smoking and diabetes. Another interesting finding in our study was that patients with hepatitis C have lower levels of cholesterol compared to patients without hepatitis C. Low cholesterol levels in these patients do not seem to be protective against future coronary heart disease events. (more…)

Robert B Belshe, MD Division of Infectious Diseases, Allergy & Immunology Saint Louis University School of MedicineMedicalResearch.com Interview with: Robert B Belshe, MD  Division of Infectious Diseases, Allergy & Immunology Saint Louis University School of Medicine   Medical Research: What are the main findings of the study? Response: A vaccine that protects against an old strain of avian flu primes the immune system to mount a rapid response when a vaccine designed to protect against a related but different and new strain of avian flu is given a year later, according to Saint Louis University research findings reported in JAMA. In addition, when combined with an adjuvant, which is a chemical that stimulates the immune system to produce more antibodies, a lower dose of the new avian flu vaccine worked better in triggering an immune response than a stronger dose without adjuvant. That means the amount of vaccine against a new strain of bird flu can be stretched to protect more people if an adjuvant is added. Both findings represent important strategies researchers can continue to study to fight new strains of bird flu that people previously have not been exposed to, and consequently can rapidly turn into a pandemic outbreak and public health emergency, said Robert Belshe, M.D., professor of infectious diseases, allergy and immunology at Saint Louis University and the lead author of the article, which appeared in the Oct. 8, 2014 issue of JAMA.

Dr. Wang:
  • The overall dietary quality in US adults improved modestly from 1999 to 2010, but the quality of US diet remains far from optimal and huge room exists for further improvements.
  • The improvement in dietary quality was greater among adults with higher socioeconomic status and healthier body weight, thus disparities that existed in 1999 increased over the next decade.
  • More than half of the improvement in diet quality was due to a large reduction in consumption of trans fat.

Sven Haller, M.D. University of Geneva in Geneva, Switzerland. MedicalResearch.com Interview with: Sven Haller, M.D. University of Geneva in Geneva, Switzerland. Medical Research: What are the main findings of the study? Dr. Haller: The main finding is that some elderly individuals with intact cognitive function at baseline already have visible alterations of the brain perfusion measured in Arterial Spin Labeling (ASL)  MRI, which is similar to patients with mild cognitive impairment (MCI). This elderly individual may initially maintain intact cognitive functions due to the activation of their cognitive reserve, yet eventually the cognitive reserve is exhausted and those individuals develop subtle cognitive decline at follow-up 18 months later. Consequently, Arterial Spin Labeling MRI may predict the very earliest form of cognitive decline. (more…)

dr_john-falconerMedicalResearch.com Interview with: John Falconer MD FRCPC Neurologist, Kelowna General Hospital; Clinical Associate Professor of Neurology, University of British Columbia Medical Research: What are the main findings of this study? Dr. Falconer: This study set out to investigate the possible benefits of having a physician with a proprietorial interest (Pro-MD) in a stroke unit, tightly combined with a multidisciplinary inter-professional team, and including the family and the patient in as essential members for the management of a stroke patient. This also involved the introduction of a geographic located Acute Stroke Unit. We compared Acute Bed Days used by patients from the five months before to five months after this system was put in place. Our main end point was number of days in acute hospital care before and after, but we also informally tracked patient and caregiver satisfaction and staff morale. The Proprietary Physician, or Pro-M Drefers to a physician who has a “proprietorial” interest in a hospital unit or ward. In other words, I was working at this unit in a wholistic sense, trying not only to manage patients as best they can, but also interested in the patient flow and family-patient communications. We found that patient bed days were reduced by approximately 25% overall, while at the same time, patient and family satisfaction was improved, and staff morale increased. Initially, we had supposed that patients and their family would be more satisfied, but we were surprised at the reduction in Acute Bed Days that resulted. (more…)

Professor Xiaodong Zhang Professor of Macromolecular Structure and Function Department of Medicine Imperial College, London, UKMedicalResearch.com Interview with: Professor Xiaodong Zhang Professor of Macromolecular Structure and Function Department of Medicine Imperial College, London, UK Medical Research: What are the main findings of the study? Prof. Zhang: Since its discovery 20 years ago, the BRCA2 gene and its protein product, BRCA2, have been under intensive investigations. The importance of the BRCA2 protein lies in the central roles it plays in the most faithful DNA damage repair pathway. Mutations in BRCA2 thus can cause defects in this repair pathway, making the repair inefficient or forcing cells to use alternative repair methods that are prone to mistakes, all of which contribute to mutations in the genomic DNA, thus increase the risk of cancer development. Our study aims to understand how BRCA2 works through studying its 3-dimensional structures and its interactions with other key partners in the repair pathway. Our study provides first 3-dimensional views of BRCA2 and BRCA2-RAD51 and reveals that BRCA2 molecules exist as pairs and a BRCA2 pair recruit two sets of RAD51 molecules arranged in opposite orientations. Our study also shows a single stranded DNA binds across the BRCA2 dimer and that BRCA2 increases the frequency of RAD51 filament formation events, presumably to increase the efficiency of establishing a longer filament required for searching for matching strands of DNA in intact sister chromatin. Our results thus not only define the precise roles of BRCA2 in helping RAD51 filament formation, but how it helps RAD51 loading onto single stranded DNA. (more…)

Lena Johansson, PhD, MSc, RN Institute of Neuroscience and Physiology Department of Psychiatry and Neurochemistry Sahlgrenska Academy at Gothenburg UniversityMedicalResearch.com Interview with: Lena Johansson, PhD, MSc, RN Institute of Neuroscience and Physiology Department of Psychiatry and Neurochemistry Sahlgrenska Academy at Gothenburg University Medical Research: What are the main findings of the study? Dr. Johansson: We found that a higher degree of neuroticism in midlife was associated with increased risk of Alzheimer’s disease over 38 years. On the 24 point scale, the risk increased with 4% per each step. Women who score high on the neuroticism scale were more likely to experience feelings such as anxiety, nervousness, worry, and irritability, and they were more moodiness and stress-prone. The association between neuroticism and Alzheimer’s disease diminished after adjusting for longstanding perceived distress symptoms, which suggest that the associations was at least partly depended on long-standing distress symptoms. When the two personality dimensions were combined, women with high neuroticism/low extraversion had a double risk of Alzheimer’s disease compared to those with low neuroticism/high extraversion.

Dr. Sundararajan: The main findings of the study are that over the last 10 years, there has been a measurable decline in people having a stroke 3 months after a new mini stroke (TIA); a mini stroke is also known as a ‘warning sign for stroke’. There has also been an overall decline in of the proportion of people having these mini strokes in the Australian State of Victoria (population 5.6million). These trends probably reflect improved primary and secondary prevention efforts for the last decade. These improvements are likely to include increased use of preventive medications and surgery for carotid artery narrowing in people identified as being at high risk of having a stroke, as well as improved behaviors (e.g. reducing smoking, improving diets, uptake of physical activity, among others). The most important aspect of our results is many fewer strokes occur when people with a TIA are managed in a hospital with a stroke unit (up to 6%).  Even when the patient’s TIA is managed in an Emergency Department and the patient released without admission, if the hospital has a stroke unit, these patients appear to have better outcomes. This likely reflects the cohesion and organization of the stroke unit in implementing the necessary tests and treatments promptly, and setting up the infrastructure to follow patients up. (more…)

Jeff R. Temple, PhD Associate Professor and Psychologist Director, Behavioral Health and Research Department of Ob/Gyn UTMB Health Galveston, TX 77555-0587MedicalResearch.com Interview with: Jeff R. Temple, PhD Associate Professor and Psychologist Director, Behavioral Health and Research Department of Ob/Gyn UTMB Health Galveston, TX 77555-0587 Medical Research: What are the main findings of the study? Dr. Temple: Through previous research, we know that teen sexting is related to actual sexual behaviors, but we did not have any information on the temporal link between these two behaviors. In short, we found that teens who sexted had 32% higher odds of being sexually active over the next year relative to youth who did not sext – this was even after controlling for history of prior sexual behavior, ethnicity, gender, and age. We also found that active sexting (actually sending a naked picture to another teen) mediated the relationship between passive sexting (asking for or being asked for a sext) and sexual behaviors. In other words, while sending a sext was predictive of subsequent sexual behavior, asking for/being asked for a sext was only associated with sexual behavior through its relationship with active sexting.

Pietro Manuel Ferraro, MD PhD Candidate Division of Nephrology Catholic University of the Sacred Heart Rome ItalyMedicalResearch.com Interview with: Pietro Manuel Ferraro, MD PhD Candidate Division of Nephrology Catholic University of the Sacred Heart Rome Italy Medical Research: What are the main findings of the study? Dr. Ferraro: We analyzed the association between caffeine intake and the risk of developing kidney stones in three large cohorts of U.S. health professionals. The 217,883 participants included did not have any history of kidney stones when follow-up began. During 20 years of follow-up, 4,982 of them developed a kidney stone. In all three cohorts, participants with higher intakes of caffeine had a reduced risk of developing kidney stones. Intake of caffeine from sources other than coffee was also associated with reduced risk of kidney stones. Among 6,033 participants with 24-hour urine data, intake of caffeine was associated with higher excretion of calcium but also higher urine volume and lower likelihood of calcium and uric acid stone formation.

Perelman Department of Dermatology NYU Langone Medical CenterMedicalResearch.com Interview with: David Polsky, MD, PhD Alfred W. Kopf, MD, professor of Dermatologic Oncology Ronald O. Perelman Department of Dermatology NYU Langone Medical Center Medical Research: What are the main findings of the study? Dr. Polsky: We utilized a multi-disciplinary approach including an analysis of socioeconomic factors to elucidate the evolution of attitudes and behaviors maximizing personal ultraviolet light exposure during the 20th century in the United States.  We then compared melanoma incidence rates from national cancer registries to estimated skin exposure and found that they rose in parallel. Though causation cannot be made in an analysis such as this one, this paper describes a historical context for the changing attitudes promoting increased UV exposure, and the rising incidence of melanoma throughout the past century.  It also provides a framework in which to consider public health and education measures that may ultimately help reverse melanoma incidence trends.

David Plurad, MD Los Angeles Biomedical Research In MedicalResearch.com Interview with: David Plurad, MD Los Angeles Biomedical Research Institute. Medical Research: What are the main findings of the study? Based on a survey of patients with traumatic brain injuries, a group of Los Angeles Biomedical Research Institute researchers found those who tested positive for tetrahydrocannabinol (THC), the active ingredient in marijuana, were more likely to survive than those who tested negative for the illicit substance. We surveyed 446 patients who were admitted to a major urban hospital with traumatic brain injuries between Jan. 1, 2010, and Dec. 31, 2012, who were also tested for the presence of THC in their urine. We found 82 of the patients had THC in their system. Of those, 2.4% died. Of the remaining patients who didn't have THC in their system, 11.5% died. While most - but not all - the deaths in the study can be attributed to the traumatic brain injury itself, it appears that both groups were similarly injured. The similarities in the injuries between the two groups led to the conclusion that testing positive for THC in the system is associated with a decreased mortality in adult patients who have sustained traumatic brain injuries.

MedicalResearch.com Interview, Sara Sammallahti, MA Institute of Behavioral Sciences University of Helsinki, Finland.   Medical Research: What are the main findings of the study? Answer: Not only did we find that faster growth right after preterm birth is associated with better neurocognitive abilities - we also showed that these effects persist into adulthood, that they are seen across a wide spectrum of abilities, and that head growth very early on seems especially relevant in predicting long-term outcomes. These associations were found when we examined 103 young adults who were born prematurely and with very low birth weight (under 1500 grams). (more…)

Dr. Forouhi: This large study found that low blood concentrations of 25-hydroxyvitamin D [25(OH)D], a clinical indicator of vitamin D status, were associated with an increased risk of type 2 diabetes, but this did not appear to be a cause-effect relationship. To investigate these associations, we did two things. We first did a systematic review and meta-analysis across 22 published studies and confirmed that there was a strong inverse relation between vitamin D levels and the risk of future new-onset type 2 diabetes among people who did not initially have diabetes. We then used a genetic approach, called Mendelian randomisation, which allows us to test a cause-effect relationship, and found that genetically lower vitamin D levels were not related to risk of type 2 diabetes. This means that we were able to distinguish between association and causation, and concluded that the vitamin D levels did not have a causal link with type 2 diabetes. (more…)

MedicalResearch.com Interview with: Kathrin S. Utz, PhD Department of Neurology University of Erlangen-Nuremberg Erlangen, German Medical Research: What are the main findings of the study? Dr. Utz: A transient ischemic attack is caused when there is a temporary disruption in the blood supply to a person’s brain. It causes the person to experience symptoms, similar to those of a stroke, such as speech and visual disturbance and numbness or weakness in the arms and legs. A transient ischemic attack is only temporary and people make a full physical recovery from it. We found, however, that a TIA is not without cost. Specifically, we found that such persons are at a greater risk of going on to develop the psychiatric condition known as posttraumatic stress disorder (PTSD). We found 1 in 3 patients develop it. PTSD, which is perhaps better known as a problem found in survivors of war zones and natural, can develop when a person experiences a frightening event that poses a serious threat. It leads the person to experience symptoms such as worry, nightmares, flashbacks and social isolation. We found that TIA patients who develop PTSD are also more likely to suffer from depression and anxiety symptoms. Taken together these symptoms pose a significant psychological burden for the affected patients and it therefore comes as no surprise that we also found TIA patients with PTSD have a measurably lower sense of quality of life than TIA patients who do not develop PTSD. We could also identify some potential risk-factors for the development of PTSD following a TIA. Younger patients and patients who overestimate their future stroke risk are more likely to develop PTSD. Also important in this context are the strategies that patients typically adopt to deal with stressful situations. Those patients who use certain types of coping strategies, such as denying the problem, blaming themselves for any difficulties or turning to drugs for comfort, face a greater risk of developing PTSD after TIA.
