MedicalResearch.com Interview  Dongyi (Tony) Du, MD, PhD Division of Epidemiology FDA/CDRH/OSB Medical Research: What are the main findings of the study? Dr. Du: The risk for death on the date of surgery was 60% higher for recipients of mechanical aortic valves than recipients of bioprosthetic aortic valves (OR, 1.61 [95%CI, 1.27-2.04; P < .001]; risk ratio [RR], 1.60). The risk difference decreased to 16% during the 30 days after the date of surgery (OR, 1.18 [95%CI, 1.09-1.28; P < .001]; RR, 1.16). The risk for operative mortality was 19% higher for recipients of mechanical compared with bioprosthetic valves (OR, 1.21 [95%CI, 1.13-1.30; P < .001]; RR, 1.19). The number needed to treat with mechanical valves to observe 1 additional death on the surgery date was 290; to observe 1 additional death within 30 days of surgery, 121.

Lex W Doyle MD BS MSc FRACP Professor of Neonatal Paediatrics Department of Obstetrics and Gynaecology The Royal Women’s Hospital Parkville, Victoria, AustraliaMedicalResearch.com Interview with: Lex W Doyle MD BS MSc FRACP Professor of Neonatal Paediatrics Department of Obstetrics and Gynaecology The Royal Women’s Hospital Parkville, Victoria, Australia Medical Research: What are the main findings of the study? Dr. Doyle: From collectively pooling data from five large trials carried out around the world over the past 20 years, we know that magnesium sulfate given under strict medical protocols in hospital to women threatening to deliver preterm reduces the risk of cerebral  palsy in their children in early childhood.  Following  from this knowledge, magnesium sulfate is now given routinely to women, under strict medical conditions, who are threatening to deliver very early in Australia, and in other parts of the world, to try to prevent cerebral palsy in their child.  What we do not know is if magnesium sulfate used this way has any longer-term effects on the brain or on other important outcomes. One of the initial studies that contributed to the overall evidence about cerebral palsy was carried out in Australia and New Zealand and completed more than 10 years ago.  Over 1000 women and their babies were enrolled in that study and although the rate of cerebral palsy was not substantially reduced by magnesium sulfate in our study, we showed that there were fewer children at 2 years of age who were not walking in the group whose mothers were given magnesium compared with those whose mothers were given placebo.  With this knowledge, and given the unknown longer-term benefits or risks, we re-evaluated the children from our study at school-age, between 6-11 years of age.  We thoroughly evaluated their brain function, including movement and co-ordination, thinking ability, behaviour, and school progress, as well as general health and well-being.  The basic message from our longer-term study is that magnesium sulfate, as used in our trial, does not have any substantial benefits or harms on brain or cognitive function, or any other outcome at school age.

Dr. Dee Fenner, M.D. Professor of Obstetrics and Gynecology Director of Gynecology University of MichiganMedicalResearch.com Interview with: Dr. Dee Fenner, M.D. Professor of Obstetrics and Gynecology Director of Gynecology University of Michigan MedicalResearch.com Editor’s note: American Medical Systems Inc. (AMS), a subsidiary of Endo International plc (Nasdaq: ENDP) (TSX: ENL), released top-line results from its TRANSFORM study that show the investigational TOPAS™ System improves fecal incontinence in women. The results show that over a 12 month period, 69% of women suffering from fecal incontinence who were implanted with the TOPAS™ System experienced at least a 50% reduction in weekly incontinence episodes and experienced a durable, consistent effect across the study period. The results were presented in Cape Town, South Africa at the International Society of University Colon & Rectal Surgeon (ISUCRS) Congress. Dr. Fenner, a primary investigator of the study, kindly answered the questions below: Medical Research: How common/prevalent is the problem of fecal incontinence in women? Dr. Fenner: Fecal incontinence, also known as accidental bowel leakage (ABL), is estimated to affect nearly 11 million women and 10% of women over the age of 20 in the United States.1,2 Additionally, nearly one in five women over the age of 45 experience ABL at least once a year.3

Sharon G. Curhan, MD, ScM Channing Division of Network Medicine Department of Internal Medicine Brigham and Women's Hospital Harvard Medical School Boston, MA 02115MedicalResearch.com Interview with: Sharon G. Curhan, MD, ScM Channing Division of Network Medicine Department of Internal Medicine Brigham and Women's Hospital Harvard Medical School Boston, MA 02115 Medical Research: What are the main findings of the study? Dr. Curhan: We followed more than 65,000 women who were participants in the Nurses’ Health Study II over 18 years and found that eating 2 or more servings of fish per week was associated with a lower risk of hearing loss. For example, after adjusting for potential confounders in multivariable analyses, in comparison with women who rarely or never ate fish, women who consumed 2 or more servings of fish per week had a 20% lower risk of hearing loss. Eating any type of fish (tuna, dark fish, light fish or shellfish) tended to be associated with lower risk. Also, we found that higher intake of long-chain omega-3 polyunsaturated fatty acids (PUFAs) was inversely associated with risk. For example, in comparison with women with the lowest intake, women with the highest intake of long-chain omega-3 PUFAs had a 22% lower risk of hearing loss.

Dr. Steve Turner Child Health, Royal Aberdeen Children's Hospital Aberdeen,UKMedicalResearch.com: Interview with: Dr. Steve Turner Child Health, Royal Aberdeen Children's Hospital Aberdeen,UK   Medical Research: What are the main findings of the study? Dr. Turner: There is evidence that being small for a given gestational age is associated with a broad range of what could be loosely considered “disadvantageous” outcomes in early childhood, eg increased risk for wheeze, increased blood fat levels, increased blood pressure and low bone mineral density.  Many of these outcomes are subclinical – ie unless they were measured no-one would be any the wiser – and what remains to be determined is whether as these individuals grow up these subclinical measurements become important.  Follow up may take many years, decades for outcomes such as coronary artery disease and type II diabetes.

Dr. Asha Devereaux: The main ethical concerns regarding eligibility for treatment during a pandemic will be access to limited or scarce resources. Who should get treatment and who decides will be some significant questions whenever there is a scarcity of healthcare resources. Transparency and the fairness of the ethical framework for decision-making will need to be made public and updated based upon the changing dynamics of resources and disease process. Dr. Niranjan Kissoon: There is work to be done in this area and engagement of citizens, government, medical community, ethicists and legal experts in the process is important.

Steven M. Bradley, MD, MPH Veterans Affairs Eastern Colorado Health CareSystem Denver, ColoradoMedicalResearch.com Interview with Steven M. Bradley, MD, MPH Veterans Affairs, Eastern Colorado Health CareSystem Denver, Colorado Medical Research: What are the main findings of the study? Dr. Bradley: In 539 hospitals participating in the CathPCI Registry that performed elective coronary angiography on more than 500,000 patients, 22% of patients were asymptomatic at the time of coronary angiography. We observed marked variation in the hospital rate of angiography performed in asymptomatic patients, ranging from 0.2% to 66.5%, suggesting broad variation in the quality of patient selection for coronary angiography across hospitals.  Additionally, hospitals with higher rates of asymptomatic patients at diagnostic angiography also had higher rates of inappropriate PCI, due to greater use of PCI in asymptomatic patients. These findings suggest that patient selection for diagnostic angiography is associated with the quality of patient selection for PCI as determined by Appropriate Use Criteria. By addressing patient selection upstream of the catheterization laboratory, we may improve on the optimal use of both angiography and PCI.

McKenzie, PhD MA Center for Injury Research and Policy The Research Institute at Nationwide Children’s Hospital Columbus, OH 43205 Medical Research: What are the main findings of the study?  Dr. McKenzie: Our main findings were that lacrosse injury rates and patterns are different by sex and by type of athletic activity. Boys’ lacrosse allows for some person-to-person contact, while girls’ lacrosse largely outlaws it. Boys had an overall injury rate of 2.26 per 1000 athletic exposures, and girls had an injury rate of 1.54 per 1000 athletic exposures. The overall injury rate was about 3 times higher in competition than in practice. We also found that sprains and strains were the most common injury diagnosis for boys and girls (boys: 35.6% of injuries; girls: 43.9%), but that concussions were a significant injury diagnosis (boys: 21.9% of injuries; girls: 22.7%).

Maurizio Gasparini, MDMedicalResearch Interview with: Maurizio Gasparini MD Humanitas Research Hospital Rozzano, Italy Medical Research: What are the main findings of the study? Dr. Gasparini: We found that a strategic programming of implantable cardioverter defibrillators which allows the non-sustained arrhythmias to self-terminate is associated with reductions in hospitalizations, length of hospital stay and cost per patient-year and an increase in the time to first hospitalization. These results were mainly driven by reduction in cardiovascular-related events.

Henry M. Spinelli, MD, PC Plastic & Reconstructive Surgery 875 Fifth Avenue New York, NY 10065MedicalResearch.com Interview with: Henry M. Spinelli, MD, PC Plastic & Reconstructive Surgery 875 Fifth Avenue New York, NY 10065 Medical Research: What are the main findings of the study? Dr. Spinelli: Briefly, we polled approximately 26,000 plastic surgeons by way of membership in the International Society of Aesthetic Plastic Surgeons (ISAPS), American Society for Aesthetic Plastic Surgery (ASAPS) and American Society of Plastic Surgeons (ASPS) and collated this data and published it in Aesthetic Plastic Surgery (the Blue Journal), the official journal of ISAPS. This preliminary study was initiated given the current and past healthcare and cosmetic medical/surgical care climate both in the United States and worldwide. As a background, when it comes to injectables (botox and fillers) there is not a united consensus on a state by state basis in the USA and from country to country worldwide. Additionally, the regulations and laws governing the administration of botox and injectables is in a constant flux. For instance, the UK allowed beauticians in the past to administer these substances however they are now banned from legal administration of these products. Alabama, only allows physicians (dermatologists and plastic surgeons) to purchase and administer botox and injectables whereas the medical board of California states that physicians can perform the procedure or oversee licensed registered nurses, licensed vocational nurses, or physicians assistants. Similarly, dentists in some states are permitted to administer these agents. It would be a bad idea for any physician working with botox to take Advanced Botox Training to reduce the possibility of medical misdemeanors. At the present time few studies have directly assessed the capability of various providers to administer cosmetic injections. When people schedule a consultation for plastic surgery, they are often looking for things like a younger face or a nicer body. The answer to the previous question will become more important as the demand for these procedures continues to grow and an increasing number of practitioners and different Plastic Surgeon from a variety of backgrounds enter the field to meet demand. This study aimed to help define the role of various practitioners in an increasingly more competitive environment for injectables and to explore the relationship between patient and injectable provider in order to improve patient satisfaction and outcomes. When asked to rank patients’ perceptions of various providers according to their expertise in administering Botox and dermal fillers, responders ranked plastic surgeons and dermatologists as most capable (96%) then nurses in plastic surgery and dermatology (3%). Gynecologists (<1%), dentists (<1%) and nurses in other fields (<1%) all received nearly equivalent numbers of “most capable” rankings. When asked to rank patients’ perception of various providers according to their inability to administer Botox and dermal fillers, nurses in other fields were most frequently ranks as least capable (63%) followed by dentists (26%), gynecologists (12%), plastic surgeons and dermatologists (2%) and nurses in plastic surgery and dermatology (1%).

Dr. Hultman: Using a mouse model of stress-induced psychiatric dysfunction, we found that the brainwave patterns in two key brain regions (prefrontal cortex, PFC and amygdala, AMY) encode for susceptibility to such dysfunction. Furthermore, such susceptibility can be predicted from the brainwave patterns in these regions before the onset of stress.

Jeff Trost, MD Assistant Professor of Medicine Johns Hopkins MedicineMedicalResearch.com Interview with: Jeff Trost, MD Assistant Professor of Medicine Johns Hopkins Medicine Medical Research: What are the main findings of the study? Dr. Trost: In our study, we reported the use of two relatively simple tactics to significantly reduce the number of unnecessary blood tests to assess symptoms of heart attack and chest pain and to achieve a large decrease in patient charges. Specifically, we
  • 1) Provided information and education to physicians about proven testing guidelines and
  • 2) Made changes to the computerized provider order entry system at the medical center, part of the Johns Hopkins Health System. The guidelines call for more limited use of blood tests for so-called cardiac biomarkers. A year after implementation, our intervention led to an estimated $1.25 million reduction in laboratory charges.

Ms Qi Wu: Mental Health and Addiction Research Group, Department of Health Sciences University of York, Heslington York UKMedicalResearch.com Interview with: Ms Qi Wu: Mental Health and Addiction Research Group, Department of Health Sciences University of York, Heslington York  UK Medical Research: What are the main findings of the study? Ms Qi Wu: At any time in the UK about one in six adults has a mental health problem, the prevalence of smoking in this group is over 33%, which is around 50% higher than in the general population. It is estimated that 3 million adults with mental disorders were smokers in 2009-10. Meanwhile, people with mental health disorders are also more likely to smoke heavily, this group accounts for as much as 42% of the total national tobacco consumption.  In this study, we calculated the avoidable economic burden of smoking in people with mental disorders. The main finding was that people with mental disorders who smoke cost the UK economy £2.34 billion a year. The total costs are more or less equally divided among losses sustained from premature death, lost productivity, and healthcare costs to treat smoking related diseases such as lung cancer, cardiovascular disease and chronic obstructive pulmonary disease (COPD) in this group.  An estimated £719 million (31% of the total cost) was spent on treating diseases caused by smoking. Productivity losses due to smoking-related diseases were about £823 million (35%) for work- related absenteeism and £797 million (34%) was associated with premature mortality.

Dr. Feltner: We conducted a systematic review and meta-analysis to assess the efficacy, comparative effectiveness, and harms of transitional care interventions to reduce readmission and mortality rates for adults hospitalized with heart failure. We included a broad range of intervention types applicable to adults transitioning from hospital to home that aimed to prevent readmissions. Although 30-day readmissions are the focus of quality measures, we also included readmissions measured over 3 to 6 months because these are common, costly, and potentially preventable. Forty-seven trials were included, most enrolled adults with moderate to severe heart failure and a mean age of 70 years. We found that interventions providing multiple home visits soon after hospital discharge can reduce 30-day readmission rates. Both home-visiting programs and multidisciplinary heart failure clinics visits can improve mortality and reduce all-cause readmission in the six months after hospitalization. Telephone support interventions do not appear to reduce all-cause readmission, but can improve survival and reduce readmission related to heart failure. Programs focused on telemonitoring or providing education only did not appear to reduce readmission or improve survival.

Mark A D’Andrea, MD, FACRO University Cancer and Diagnostic Centers Houston, TexasMedicalResearch.com Interview with: Mark A D’Andrea, MD, FACRO University Cancer and Diagnostic Centers Houston, Texas   MedicalResearch: What are the main findings of the study? Dr. D’Andrea: Crude oil spills affect the human health through their exposure to the inherent hazardous chemicals such as para-phenols and volatile benzene. Human exposure to crude oil spills is associated with multiple adverse health effects including hematopoietic, hepatic, renal, and pulmonary abnormalities. In this study, we assessed the hematological and liver function indices among the subjects participated in the Gulf oil spill clean-up operations along the coast of Louisiana. The findings were compared with the standardized normal range reference values. We found that over 77% of subjects had WBC counts in the mid range (6 - 10X 103 per mL) while none of the subjects had upper limit of the normal range (11 X 103 per mL). Similar pattern was seen in the platelet counts and BUN levels among the oil spill exposed subjects. Conversely, over 70% of the subjects had creatinine levels toward upper limit of the normal and 23% of subjects had creatinine levels above the upper limit of the normal range (> 1.3 mg per dL). Similarly, hemoglobin and hematocrit levels were toward the upper limit of the normal in more than two-third of the subjects. Aspartate amino transferase and alanine amino transferase levels above the upper limit of normal range (> 40 IU per L) were seen in 15% and 31% of subjects, respectively. Over 80% of subjects had urinary phenol levels more than detectable levels (2 mg per L).

Professor Bennell: In 102 people with painful hip osteoarthritis, we compared a 'real' physical therapy program involving exercise, manual therapy techniques,education and provision of a cane if appropriate to a sham physical therapy treatment that was made to look as though it was real but instead involved turned off ultrasound and gentle application of a hand crème to the hip region. Participants in both groups went to see a physical therapist on 10 occasions over 12 weeks and performed home exercises if in the 'real' physical therapy group or lightly applied the cream at home if in the sham group. Participants were followed for 9 months in total. We found that while both groups showed improvements in pain and physical function, the improvements were similar between the two groups. That is, the real physical therapy program did not show greater benefits over a sham treatment.

MedicalResearch.com Interview withTimothy Fernandes, M.D., M.P.H. University of California, San Diego - La Jolla, CA Timothy Fernandes, M.D., M.P.H. University of California, San Diego La Jolla, CA MedicalResearch: What are the main findings of this study? Dr. Fernandes: The fibrinopeptides are cleaved off of fibrinogen by thrombin during the generation of a new clot. These small molecules are excreted into the urine and we have developed a urine assay to measure the level of FPB. We examined the performance of urine FPB as a screening test for acute pulmonary embolism, blood clots that travel to the lungs. The study group consisted of 344 patients: 61 (18%) with pulmonary embolism and 283 (83%) without. At a threshold of 2.5 ng/ml, urine FPB demonstrated sensitivity of 75.4% (95% CI: 62.4-85.2%), specificity of 28.9% (95% CI: 23.8-34.7%), and negative likelihood ratio of 0.18 (0.11-0.29), weighted by prevalence in the sample population. However, the thresholds of 5 ng/ml and 7.5 ng/ml had sensitivities of only 55.7% (95% CI: 42.5-68.2%), and 42.6% (30.3-55.9%), respectively. The urine fibrinopeptide B assay at a cut-off of 2.5 ng/ml had a sensitivity of 75.4% for detecting pulmonary embolism. For diagnosis of PE, this sensitivity is comparable to previously published values for the first generation plasma latex and whole blood D-dimer assays (not as well and the D dimer ELISA assay).

MedicalResearch.com Interview with Dr. Michael Johansen, MD, MS Department of Family Medicine The Ohio State University Columbus, OH 43201 MedicalResearch: What are the main findings of the study? Dr. Johansen: We found a surprisingly low number of people with coronary artery disease and diabetes (over age 40) were not reporting statin use. Of the people with coronary artery disease only 58% reported statin use while 52% of people with diabetes reported use. In addition, a reported diagnosis of hyperlipidemia was strongly correlated with statin use. In fact, individuals with hyperlipidemia and no coronary artery disease were more apt to be on a statin than people with coronary artery disease and no hyperlipidemia. Other high-risk conditions that have recently been included in the ACC/AHA high risk category were weakly or not associated with statin use including stroke and peripheral arterial disease.

Dr. J van der Meer: The main finding of our study is that the prognosis of patients with compensated HCV-induced advanced liver disease can be adequately assessed by risk scores which merely include objective variables that are readily available in daily practice. Our analyses resulted in two separate prognostic scores by which the individual patient's risk of mortality or clinical disease progression (defined as occurence of Hepatitis C Cirrhosis (HCC), liver failure, liver transplantation or death) can be assessed.

MedicalResearch.com: Egle Avizienyte, PhD Senior Research Fellow, Institute of Cancer Sciences Faculty of Medical and Human Sciences The University of Manchester, Manchester M20 4BX MedicalResearch.com: What are the main findings of the study? Dr. Avizienyte: Angiogenesis, the formation of new blood vessels, has been validated as a target in ovarian cancer. However, the benefit from anti-angiogenic therapies, e.g. Vascular Endothelial Growth Factor (VEGF) pathway inhibitors that are currently used in the clinic for the treatment of ovarian cancer has been modest, largely because of redundancy in angiogenic cytokines that regulate tumour angiogenesis. In this study we validated heparan sulphate 6-O-sulfotranferases 1 and 2 (HS6ST-1 and -2) as targets for developing new therapeutic anti-angiogenic agents for the treatment of ovarian cancer. The data generated in our laboratory show that HS6STs induce the angiogenic programme in ovarian cancer cells and has a major effect on tumour angiogenesis.

MedicalResearch.com Interview with Stephen M. Amrock, SM Department of Pediatrics New York University School of Medicine New York, NY 10016 MedicalResearch.com: What are the main findings of the study? Answer: We analyzed data from a nationally representative survey on youth risk behaviors. After adjusting for other risk taking behaviors, we found that high school adolescents who indoor tan were much more likely to also engage in behaviors typically associated with eating disorders. We also noted that the link between indoor tanning and such harmful weight control behaviors was even stronger among males than females.
