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.

Paula Berstad, PhD, postdoc Telemark Hospital c/o Cancer Registry of Norway Oslo, NorwayMedicalResearch.com Interview Invitation Paula Berstad, PhD, postdoc Telemark Hospital c/o Cancer Registry of Norway Oslo, Norway   Medical Research: What are the main findings of the study? Dr. Berstad: In general population of age 50-55 years, both those invited to bowel cancer screening in year 2001 by flexible sigmoidoscopy and those not invited improved their lifestyle from year 2001 to 2012. Lifestyle was measured as adherence to public health guidelines; non-smoking, daily physical exercise, healthy diet and normal body weight. However, the 11-year improvement was smaller in those who were screened for bowel cancer compared to those not screened. Further, among those who attended the screening, the improvement was smaller in those with findings at screening (positive screening result) compared to those without findings (negative screening result). Our interpretation of the findings is that bowel cancer screening may have a small unwanted effect on lifestyle. Particularly, attention should be given to lifestyle among those testing positive at screening. (more…)

Answer: Our research team identified a molten salt, choline-geranate, that possessed multiple beneficial biological traits. Specifically, when mixed in a 1:2 ratio (choline:geranate) this solvent is able to effectively disrupt and neutralize 72-hour biofilms formed by both Pseudomonas aeruginosa and Salmonella enterica. Further, our studies demonstrated the same solvent exhibited minimal cytotoxicity effects to normal human bronchial epithelial (NHBE) cells and was able to deliver an antibiotic, cefadroxil, through the stratum corneum into the epidermis and dermis. Most importantly, the research culminated in demonstrating the molten salt was able to neutralize ~95% of the bacteria found within a 24-hour P. aeruginosa biofilm when grown on a skin wound model (MatTek)  and ~98% of the bacteria when formulated with the antibiotic, ceftazidime. When the biofilm was treated with only antibiotic in a saline solution, less than 20% of the bacteria were neutralized. (more…)

Dr. Lallukka: Our study used nationally representative survey data linked with register data on medically certified sickness absence among working -aged Finnish women and men. We showed consistent associations between insomnia symptoms, sleep duration, and being tired and sickness absence. The follow-up lasted around 7 years. Sickness absence days were derived from comprehensive registers from the Social Insurance Institution of Finland. The associations were broadly similar among women and men. Furthermore, they remained even after considering key correlates of sleep and sickness absence including socioeconomic position, working conditions, health behaviors, obesity, and mental and physical health. Health data were derived from physical examination conducted by field physicians. These data are more objective, and help provide more robust evidence. We further covered all key sleep disturbances and sleep duration for more comprehensive understanding about the contribution of sleep to sickness absence. Finally, a novel method developed by the authors (Härkänen & Kaikkonen) allowed us to estimate the difference in sickness absence days per working year among those reporting and not reporting different sleep disturbances. Using the difference in days absent from work, we were further able to estimate the hypothetical direct costs of sickness absence highlighting notable societal significance of sleep. Thus, a large part of all costs of sickness absence are attributable to poor sleep. For example, those sleeping 5 hours or less or 10 hours or more, were absent from work ca 5-9 days more, as compared to those with optimal sleep length. The optimal sleep length with the lowest risk of sickness absence was 7 hours 46 minutes for men and 7 hours 38 minutes for women. (more…)

Medical Research: What are the main findings of the study?

Prof. Zhang: Higher heart rate has emerged as a cardiovascular risk factor and is associated with higher mortality rate. However the mechanistic link between heart rate and mortality outcome in population has been missing. The main findings of the present study in a relatively large population are two-fold: Firstly, there is a strong and positive association between resting heart rate and metabolic syndrome, which is defined when an adult has 3 of the following: obesity (waist circumference ≥90 cm for men or ≥80 for women); hypertriglyceridemia (triglycerides ≥1.7 mmol/L); low plasma level of high-density lipoprotein <1.03 mmol/L for men or <1.30 mmol/L for women); hypertension (systolic blood pressure/ diastolic blood pressure≥130/85 mmHg or current use of antihypertensive medications); hyperglycemia (fast blood glucose ≥5.6 mmol/L or previously diagnosed type 2 diabetes or current use of hypoglycaemic agents or insulin). Secondly and more importantly, those without metabolic syndrome but with higher resting heart rate will have greater risk in developing metabolic syndrome in the near future. As such, the findings from both cross-sectional and longitudinal studies provide evidence that resting heart rate is an independent risk factor for existing metabolic syndrome and a powerful predictor for its future incidence.

Dr. Ruwald: A high percentage of biventricular pacing is required for optimal outcome in patients treated with cardiac resynchronization therapy (CRT), but the influence of ectopic beats on the success of biventricular pacing has not been well established. We found that patients with increasing amount of ectopic beats (the ectopic burden) (≥0.1%) were more likely to achieve low biventricular pacing <97% and had higher risk of heart failure or death and ventricular arrhythmias. Similarly the study identified patients with a very low amount of ectopic beats, less than 1 in 1000, who are very likely to obtain high biventricular pacing and who have very low risk of adverse outcomes.

MedicalResearch.com Interview with: Nenette M. Jessup MPH, CCRP Research Associate/Project Manager TASK II Indiana University School of Nursing Indianapolis, IN 46202 Medical Research: What are the main findings of the study? Dr. Jessup: Similar to others, we found that females and non-African American caregivers experienced more depressive symptoms and females perceived greater task difficulty. Because female caregivers comprise the largest group of caregivers in the United States, the consistency of this finding has implications for continued social policy efforts to improve their plight. However, our results also suggested an interaction effect between race and type of relationship, with African American spouses experiencing the most difficulty with tasks of caregiving. Inconsistencies in the existing literature about this finding signal the need for a greater understanding of group differences. Individualized interventions may also be of benefit for stroke caregivers. (more…)

Dr. Couderc: We have developed a unique technology which enables any individual to evaluate if he/she suffers from atrial fibrillation (AF) by using a simple video camera (webcam). There are approximately 3.2 million people with AF in the US, and estimated 30 million people in the world. It has been shown that around 30% of people suffering from AF are not aware of their disease, this form is called 'silent' atrial fibrillation.  AF is a progressive disease leading to stroke and heart failure.  It results in significant morbidity and mortality. The total cost of AF in the US is estimated to $7billion and 75% of this cost is associated with patient hospitalization. (more…)

Medical Research: What are the main findings of the study? Dr. Nylund: The main findings of our study were that among children who were identified as having a diagnosis of Clostridium difficile infection (CDI), CDI was about twice as likely to occur during periods when the child was taking either a proton pump inhibitor or histamine-2 receptor antagonist. In brief, we performed a type of observational study called a self-controlled case series. Our data source was the military health system database which contains billing records for patients seen in military and civilian facilities. We identified all cases of Clostridium difficile infections in children ages 2-18 over the period of October 2001 to July 2013. We also identified periods when children were prescribed both proton pump inhibitors and histamine-2 receptor antagonists over the same time period. We compared the incidence of CDI during periods prescribed acid suppression medications to periods not prescribed these medications. (more…)

Medical Research: What are the main findings of the study? Dr. Cao: The major goal of this study was to investigate the effect of Ä9-tetrahydrocannabinol (THC), a major component of marijuana, on Alzheimer’s disease (AD) pathology. THC has long been known to have anti-inflammatory effects, but we were looking to determine whether THC directly affected amyloid beta (Aâ). Aâ aggregation is considered one of the key pathological hallmarks of Alzheimer’s disease. Our study showed that extremely low doses of THC were able to decrease Aâ production, inhibit Aâ aggregation, and enhance mitochondrial function in a cellular model of AD. Decreased levels of amyloid beta, coupled with THC’s inhibitory effect on aggregation may protect against the progression of Alzheimer’s disease. (more…)

Dr. Bingener: Other investigators have shown that preoperative quality of life is a predictor for postoperative survival in colon and pancreas cancer surgery. In this study we looked as preoperative quality of life as a predictor for postoperative complications. The main findings of the study were that patients who had a deficit in their quality of life before surgery had a 3 times higher risk of a serious complication before leaving the hospital than patients who had normal quality of life (16% vs 6 %), independent of gender, race, tumor stage or laparoscopic or open colectomy. Patients with serious complications before leaving the hospital also were older and had more other medical problems than patients without complications. Further, patients who had a complication stayed in the hospital longer and their postoperative quality of life was worse (more…)

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

Dr. Johnston:
  • Our findings represent the first meta-analysis using advanced epidemiological methods to summarize popular branded diets for weight loss, trials having been investigated using randomized trial methodology.
  • Among the 48 original RCTs included in our NMA, low to moderate quality evidence showed that both low-carbohydrate and low-fat diets were associated with an approximate 8 kg weight loss at 6 months when compared to no diet. Approximately 1-2 kg of this effect was lost by 12-months.
  • Although statistical differences existed among several of the diet macronutrient classes, the differences were small and unlikely to be important to those seeking to lose weight.
  • Similarly, our results showed that although there are statistically significant differences between some of the brand named diets, these differences are small and not likely patient important.
  • In terms of potential effect modifiers, behavioural support was significant at 6-months (enhancing weight-loss by 3.23 kg) and exercise was significant at 12-months (enhancing weight loss by 2.13 kg)
  • Regarding our sensitivity analyses, Differences in weight loss were not clinically important based on risk of bias, missing data, baseline weight, gender, and those with and without specific health conditions
  • Overall, our findings suggest that patients may choose, among those associated with the largest weight loss, the diet that gives them the least challenges with adherence.

MedicalResearch.com Interview with: Tian Hu, MD, MS Research Fellow ​Department of Epidemiology, Tulane University School of Public Health and Tropical Medicine New Orleans, LA 70112 Medical Research: What are the main findings of the study? Dr. Hu: Participants on the low-carbohydrate diet lost more weight than those on the low-fat diet at 3, 6, and 12 months. At 12 months, those in the low-carbohydrate group lost an average of almost 8 pounds more than those in the low-fat group. Participants on the low-carbohydrate diet lost more fat mass and did not lose lean mass (muscle) compared to those on the low-fat diet. Overall, bad cholesterol (low-density lipoprotein cholesterol) that is a predictor of risk for cardiovascular disease decreased on both diets, but good cholesterol (high-density lipoprotein cholesterol) increased more in the low-carbohydrate group. Physical activity was similar in the groups throughout the study, suggesting that the greater weight loss among participants in the low-carbohydrate group was not because they exercised more. When we evaluated the black and white participants separately, the results were similar. (more…)

Dr. Montalescot : Among the 1862 patients with ongoing STEMI who were enrolled in the ATLANTIC study, we found no difference between those randomized to pre-hospital (in-ambulance) ticagrelor 180 mg and those randomized to in-hospital (in-catheterization laboratory) ticagrelor 180 mg in terms of either pre-PCI ST-segment elevation resolution (≥70%) or pre-PCI TIMI 3 flow in the culprit artery, which were the co-primary endpoints. There was also no difference between the groups in terms of major adverse cardiovascular events at 30 days, with the exception that rates of definite stent thrombosis were lower in the pre-hospital ticagrelor group than in the in-hospital group, both in the first 24 hours (0% versus 0.8%, p= 0.008) and at 30 days (0.2% versus 1.2%, p = 0.02). The safety of pre-hospital ticagrelor did not appear to be an issue, since the incidence of non-CABG-related major bleeding was low and similar in both treatment groups, whichever bleeding definition was used (PLATO, TIMI, STEEPLE, GUSTO, ISTH or BARC).

Massimo Imazio. MD, FESC Dipartimento di Cardiologia/Cardiology Department Maria Vittoria Hospital and University of Torino Torino, ItaliaMedicalResearch.com Interview with: Massimo Imazio on behalf of the COPPS-2 Investigators Massimo Imazio. MD, FESC Dipartimento di Cardiologia/Cardiology Department Maria Vittoria Hospital and University of Torino Torino, Italia Medical Research: What is the background for this investigation? Dr. Imazio: Post-pericardiotomy syndrome, post-operative atrial fibrillation (AF), and post-operative effusions may be responsible for increased morbidity and healthcare costs after cardiac surgery. Postoperative use of colchicine prevented these complications in a single trial (the COPPS trial published on EHJ in 2010). Here all events occurred within 3 months and colchicine was given after cardiac surgery starting from postoperative day 3 for 1 month. However most postoperative AF events are reported in the first 3 days and thus pre-treatment with colchicine may give better outcomes. Thus we performed the COPPS-2 giving colchicine 48 to 72 hours before surgery for 1 month without a loading dose and weight adjusted doses (i.e. 0.5 mg twice daily for patients >70kg or 0.5 mg once for patients <70Kg) in order to improve patients compliance.The Colchicine for Prevention of the Post-pericardiotomy Syndrome and post-operative atrial fibrillation (COPPS-2 trial) is an investigator-initiated, double-blind, placebo-controlled, randomized clinical trial. A total of 360 consecutive candidates for cardiac surgery, 180 for each arm, were enrolled in 11 Italian centers between March 2012 and March 2014. Main exclusion criteria were absence of sinus rhythm at enrollment, cardiac transplantation, and contraindications to . (more…)

McMurray, M.D Professor of Medical Cardiology British Heart Foundation, Cardiovascular Research Centre University of Glasgow, Glasgow, United Kingdom Medical Research: What are the main findings of the study? Dr. McMurray: That compared to an evidence-based dose of an evidence-based ACE inhibitor (enalapril 10 mg bid), LCZ696 reduced the primary composite outcome of cardiovascular death or heart failure hospitalization by 20%, both the components of that composite and all-cause mortality (the latter by 16%) - all reductions are highly statistically significant and clinically important. LCZ696 treated patients also reported fewer symptoms and physical limitations due to heart failure. We think this is a remarkable finding - to beat what has been the gold-standard, cornerstone, therapy for around 25 years. The findings show conclusively that adding neprilysin inhibition to renin-angiotensin system blockade is superior to renin-angiotensin system blockade alone in patients with heart failure and reduced ejection fraction .

MedicalResearch.com Interview with:  Michelle Scollo Senior policy adviser, Tobacco Centre for Behavioural Research in Cancer Medical Research: What are the main findings of the study? Answer:  Each November the Cancer Council Victoria conducts a survey asking smokers about their tobacco purchasing habits and smoking attitudes, intentions and behaviours. This study compared what smokers said about where and what they purchased in:
  • November 2011, a year before the introduction of world-first legislation mandating standardized packaging of tobacco products throughout Australia
  • In November 2012, while the new plain packs were being rolled out onto the market and
  • In November 2013 one year later.
The tobacco industry had strenuously opposed the legislation, but—contrary to the industry predictions and continuing claims in other countries contemplating similar legislation—we found: 1.       No evidence of smokers shifting from purchasing in small independent outlets to purchasing in larger supermarkets 2.       No evidence of an increase in use of very cheap brands of cigarettes manufactured by companies based in Asia and 3.       No evidence of an increase in use of illicit unbranded tobacco.

Dr. Gilron: Pain is the most common symptom which prevents recovery from surgery. Even with the best available treatments today, many patients still suffer from moderate to severe pain after surgery. Antidepressants - drugs used to treat depression - are also proven effective for treating chronic pain due to nerve disease and fibromyalgia. However, there has been much less research on the effects of antidepressant drugs on pain after surgery. Our group conducted a systematic review of all published clinical trials of antidepressant for post surgical pain. Slightly more than half of these studies suggested some benefit of these drugs but the details of this review led us to conclude that there is not yet enough evidence to recommend these medications for post surgical pain treatment. Given the possibility that these medications could be useful treatments for pain after surgery, we believe that future studies of higher scientific quality and which involve larger numbers of patients should be carried out in the hopes of finding safer and more effective treatments for pain after surgery.
