Western Australia MedicalResearch.com: What are the main findings of your study? Answer: Our research indicates that consuming larger quantities of foods included in a western dietary pattern is associated with greater cognitive decline in visuospatial functioning after 36 months. Foods included in the western dietary pattern are red and processed meats, high fat dairy products, chips, refined grains, potatoes, sweets and condiments. Visuospatial functioning is an area which includes distance and depth perception, reproducing drawings and using components to construct objects or shapes. In contrast, adherence to the Mediterranean diet, a healthy eating pattern is associated with less decline in executive function. Foods included in the Mediterranean diet are vegetables, fruits and fish. Examples of executive function include planning and organising, problem solving and time management. (more…)

Dr. Alexander:
  • There have been large shifts in the types of treatments used to treat Type 2 diabetes during the past decade in the United States.
  • We document large declines in the use of glitazones and sulfonylureas and important increases in the use of the newer DPP-4 inhibitors and GLP-1 agonists.
  • We also found large shifts in the types of insulins used, with substantial reductions in the use of regular and intermediate insulins, and large increases in the use of long-acting and ultra short-acting  therapies.
  • Costs have increased significantly over the past 5 years, driven primarily by insulin and DPP-4 inhibitors
  • All of these changes notwithstanding, biguanides continue to remain a mainstay of therapy. (more…)

Dr. Lorenzo: Metabolically healthy obese individuals are at increased risk of developing of diabetes and cardiovascular disease. These findings were demonstrated in men and women and in Mexican Americans and non-Hispanic whites. Management of excess weight and any metabolic abnormality appears to be important for all individuals. Our study is also in agreement with previous studies that indicate that metabolically unhealthy normal weight individuals are at increased risk of developing of diabetes and cardiovascular disease.

Author Interviews, BMJ, Hospital Readmissions / 21.11.2013

Kumar Dharmarajan MD MBA Fellow in Cardiovascular Medicine Columbia University Medical CenterMedicalResearch.com Interview with: Kumar Dharmarajan MD MBA Fellow in Cardiovascular Medicine Columbia University Medical Center MedicalResearch.com: What were the main findings of the study Dr. Dharmarajan: In the United States, 1 in 5 older patients is readmitted to the hospital within 30 days of hospital discharge. However, there is great variation in rates of 30-day readmission across hospitals, and we do not know why some hospitals are able to achieve much lower readmission rates than others. We therefore wondered whether top performing hospitals with low 30-day readmission rates are systematically better at preventing readmissions from particular conditions or time periods after discharge. For example, are hospitals with low 30-day readmission rates after hospitalization for heart failure especially good at preventing readmissions due to recurrent heart failure or possible complications of treatment? Similarly, are top performing hospitals especially good at preventing readmissions that occur very soon after discharge, which may signify poor transitional care as the patient moves form the hospital back home?

Dr. Nuovo: The main finding of the study was that idiopathic pulmonary fibrosis was strongly associated with an infection by a herpesvirus.  The data that supported this main finding included:
  • 1) detection of the viral DNA by in situ hybridization in each case of idiopathic pulmonary fibrosis (IPF) and in none of the controls;
  • 2) the localization of the viral DNA to the nucleus of the cell that orchestrates IPF, the regenerating epithelial cell (herpes viruses localize to the nucleus of the target cell);
  • 3) the demonstration that the viral DNA co-localized with "pirated proteins" that the virus makes during productive infection (these were IL-17. cyclin D, dihydrofolate reductase, and thymidylate synthase); this combination of proteins are rarely if ever co-expressed in lung disease and  their co-expression per se was highly suggestive of a viral infection;
  • 4) the demonstration by RTPCR that the cyclin D RNA in IPF comes from the virus and not the human cells;
  • 5) the recognition that this family of herpesviruses (called gammaherpesvirus) causes IPF in other animals including horses, mice, and donkeys;
  • 6) the cloning of part of the gene of the virus from a clinical IPF sample that showed 100% homology to the published sequence of the likely viral pathogen - herpesvirus saimiri. (more…)

Dr. Kathryn Orzech PhD Postdoctoral fellow,Charting the Digital Lifespan University of Dundee, Scotland, UKMedicalResearch.com Interview with: Dr. Kathryn Orzech  PhD Postdoctoral fellow,Charting the Digital Lifespan University of Dundee, Scotland, UK   MedicalResesarch.com: What are the main findings of the study? Dr. Orzech: We found that acute illnesses, such as colds, flu, and gastroenteritis were more common among healthy adolescents with shorter sleep.  Specifically, our main analysis found that reported bouts of illness (analyzed on a bouts-of-illness-per-interview basis) declined with longer sleep for both male and female high school students.  Longer sleep was also generally protective against school absences that students attributed to illness. There were sex differences, with males reporting fewer illness bouts than females, even with similar sleep durations.  This is consistent with another recent study that showed a lower impact of shorter sleep on male adolescents (in that case the outcome was male adiposity), but more research is needed. We also conducted a secondary analysis to examine total sleep time in matched 6-day windows before illness and before wellness in the same adolescents. Although the number of participants who met our strict criteria for a healthy 6-day window before illness or wellness was only 18 (I was amazed at how difficult it was to find adolescents who reported being completely well for 6 consecutive days), we were able to see a trend in the data toward shorter sleep before illness vs. wellness. Because of the difficulty in comparing sleep before illness vs. wellness, we conducted a qualitative analysis as well, choosing two 17 year old males who were both shorter sleepers, but who reported very different illness profiles - 0 days of illness vs. 35 days of illness across the school term. An in-depth look at notes made by interviewers allowed us to create brief case studies to illustrate that not all shorter sleepers are alike.  More irregular sleep timing across weeknights and weekends (much shorter sleep during the week and longer sleep times on the weekend), and a preference for scheduling work and social time later in the evening hours may both contribute to differences in illness outcomes.

Dr. Abigail Powers PhD Clinical Psychology Postdoctoral Fellow Emory University School of Medicine MedicalResearch.com: What are the main findings of the study? Dr. Powers: Personality disorders (i.e., problematic personality patterns that cause significant distress and dysfunction in individuals’ lives across many areas of functioning) are associated with many negative health outcomes in young adulthood. The goal of this research study was to determine the relationship between personality pathology and medical resource utilization as individuals age and develop new physical health problems.  Among community-dwelling later middle-aged adults (ages 55-64), we found that personality pathology was related to higher reported medical resource utilization (including doctor visits, hospitalizations, and number of outpatient procedures) independent of health status. Of the 10 DSM-IV personality disorders assessed, narcissistic and antisocial personality disorder features were associated with greater medical resource utilization independent of the presence of physical health problems. Also, among individuals with a greater number of physical health problems, histrionic and dependent personality disorder features were related to greater medical resource utilization, suggesting that important interactions between personality pathology and health conditions may occur in older age and impact resource use.

Dr. Murphy: This study evaluated racial disparity in metastatic colorectal cancer. In a large population-based cohort we found of over 11,000 patients we found that black patients were less likely to be seen in consultation by a cancer specialist, and were less likely to receive treatment with chemotherapy, surgery, or radiation. Furthermore, we found that this disparity in treatment accounted for a substantial portion of the race-based differences between black and white patients. (more…)

Dr. El Shayeb: Our study shows that limited channel level-3 portable devices, used at home, are of good diagnostic value compared to the comprehensive reference-standard level-1 sleep tests conducted in lab in the diagnosis of obstructive sleep apnea (the most common subtype of sleep disordered breathing.)

Were any of the findings unexpected? None of the findings were unexpected. Level-3 portable devices are commonly used in clinical practice; however, this technology has been widely disseminated, without solid evidence about their diagnostic performance or the subpopulation of sleep disordered breathing patients who are most appropriately diagnosed with them. Our research provides a high level of evidence on the diagnostic performance of these devices, and most importantly, defines the subgroup of patients who are eligible for this test (patients with simple obstructive sleep apnea, and without significant comorbidities.)

Leung, MD, MSc Clinical Assistant Professor of Medicine Division of Endocrinology, Department of Medicine University of California Los Angeles   MedicalResearch.com: What are the main findings of the study? Dr. Leung: Despite current guidelines to screen for thyroid dysfunction as a secondary cause of newly-diagnosed hyperlipidemia, this was performed only about 50% of the time by primary care providers in over 8,700 patients at a large, urban Boston academic medical center. Approximately 5% of patients who had thyroid function checked were found to have hypothyroidism. The majority of hypothyroid patients who received treatment with levothyroxine had successful correction of the initial hyperlipidemia within one year. (more…)

MedicalResearch.com Interview with: Guang Sun MD, PhD Professor, Discipline of medicine Faculty of medicine, Memorial University Canada MedicalResearch.com:  What are the main findings of the study? Dr. Sun: Plenty of anecdotal reports on how ‘Food Addiction’ may be a potential culprit of the rising prevalence of obesity. However to date no scientific study, based on a comprehensive criterion of the diagnosis of Food Addiction, has been performed at the population level. The main findings are in the following fours aspects: 1)         Food Addiction is indeed an important contributing factor in the development of obesity. 2)         The prevalence of Food Addition was 5.4% and increased concomitantly with obesity status defined by either body mass index (BMI) or body fat percentage (%BF). In another word, there is one food addict in every twenty adults (Newfoundland Province, Canada) 3)         Clinical Symptom Count(s) of Food Addiction is strongly associated with the severity of obesity. 4)         Women are twice as likely to be diagnosed with “Food Addiction” than men.

MedicalResearch.com Interview with: Nina Berentzen Centre for Nutrition, Prevention and Health Services National Institute for Public Health and the Environment Bilthoven The Netherlands MedicalResearch.com: What are the main findings of the study? Answer: This study in 11-12 year old children shows that self-reported characteristics of sleep quality were not associated with blood pressure and HbA1c; and that in girls, but not in boys, some sleep characteristics were associated with anthropometric outcomes (BMI, waist circumference) and cholesterol levels. More specifically, in girls, longer time in bed was associated with lower BMI and waist circumference; having night-time awakenings with higher total cholesterol, going late to bed while rising early with higher total and HDL cholesterol; and feeling sleepy/tired during daytime with lower HDL cholesterol and with higher total-to-HDL cholesterol ratio. We report new findings for daytime outcomes of sleep quality that were not studied before in relation to cardiometabolic risk; e.g. difficulty with getting up in the morning, feeling rested after waking, and feeling sleepy or tired during the day. Our study therefore offers insight not only in characteristics of sleep at night, but also in consequences of sleep during the day. (more…)

Answer: Our main goal was to investigate gender-related interactions between obstructive sleep apnea (OSA) and obesity while taking associated metabolic abnormalities into account. We analyzed 423 men and 105 women previously studied for the association of OSA and the Metabolic Syndrome (MetS) (Bonsignore et al, Eur Respir J, 2012), to assess whether markers of general and visceral obesity were differently associated with OSA in men and women. Multivariate analysis showed that in men the apnea-hypopnea index (AHI), an indicator of OSA severity, was associated with waist circumference, a marker of visceral obesity, and body mass index (BMI); conversely, in women AHI was associated with hip circumference, a marker of subcutaneous fat deposition, and neck size.  The results were similar when patients without a diagnosis of MetS were analyzed; conversely, in patients with MetS, waist circumference was the only significant marker of OSA in both genders.

Thomas M. Hooton M.D. Associate Chief of Staff, Medical Service, Miami VA Healthcare System Professor of Clinical Medicine and Vice Chair for VA Affairs, Department of Medicine, UMSOM Clinical Director, Division of Infectious Diseases, UMSOMMedicalResearch.com Interview with: Thomas M. Hooton M.D. Professor of Medicine and Vice Chair for VA Affairs, University of Miami Miller School of Medicine Associate Chief of Staff, Medical Service, Miami VA Healthcare System Clinical Director, Division of Infectious Diseases MedicalResearch.com: What are the main findings of the study? Dr. Hooten: The main findings from this study are: ·        Voided urine colony counts of E. coli as low as 101 to 102 cfu/mL are highly sensitive and specific for their presence in bladder urine in symptomatic women (growth of bacteria in bladder urine is the gold standard for the etiology of UTI). Moreover, even when E. coli is found along with other mixed flora in voided urine, it should not be considered a contaminant since it likely represents true bladder infection. ·        On the other hand, enterococci and Group B streptococci, which are frequently isolated from voided urine, are rarely isolated from paired catheter specimens, suggesting that these organisms only rarely cause acute uncomplicated cystitis. In our study, E. coli frequently grew from the urines of these women and is the likely cause for UTI symptoms in such episodes. ·        Organisms usually considered contaminants, such as lactobacilli, occasionally grow from catheter urines, but they are rarely found alone with pyuria, suggesting that these bacteria rarely cause acute uncomplicated cystitis. ·        The etiology of a quarter of acute uncomplicated cystitis episodes is unknown.  It is possible that some of these women have E. coli urethritis, which has been documented in some women with UTI symptoms, but we did not do further studies to evaluate this. It is possible also that enterococci and Group B streptococci may also cause urethritis, but there is no published evidence of this in young women with UTI symptoms. ·        Although voided urine cultures growing mixed flora are common in women with acute cystitis, true polymicrobic cystitis, as determined by sampling bladder urine, appears to be rare in this population.

Madrid 12; 18012 Granada (Spain) MedicalResearch.com: What are the main findings of the study? Answer: In conclusion, the results of the present study showed that a higher chocolate consumption was associated with lower levels of central and total fatness in European adolescents. Of note is that the observed association was independent of total energy intake and saturated fat intake as well as objectively measured physical activity. In addition, results remained unchanged after adjusting for foods with high catechins concentration as fruit, vegetables and tea; as well as other products such as coffee that could influence the observed association between chocolate consumption and markers of total and central body fat.

MedicalResearch.com with: Dr Kate Mandeville MD MPH Clinical Research Fellow, London School of Hygiene and Tropical MedicineDr Kate Mandeville MD MPH Clinical Research Fellow, London School of Hygiene and Tropical Medicine   MedicalResearch.com: What is the background for your study? Dr. Mandeville: The UK spent nearly one billion pounds on pharmaceutical drugs during the swine flu pandemic, including vaccine and antiviral drugs. After the swine flu pandemic, it was revealed that some scientists on the World Health Organization’s advisory committee had links with the pharmaceutical industry. Scientists often provide commentary for journalists on emerging health risks and we set out to see whether scientists commentating on swine flu were also more likely to have links to pharmaceutical companies. We analysed UK newspaper coverage of the swine flu pandemic between April and July 2009. This was the period in which the UK government was making decisions on how best to respond to the emerging pandemic, including providing the public with vaccine and antiviral drugs. We looked for how often scientists were quoted in articles on the pandemic from a wide range of newspapers. We then examined these comments in more detail to see if scientists made an assessment of the risk to the public from swine flu, and compared these against assessments made by official agencies like the Department of Health. We also judged whether the scientists promoted or rejected the use of vaccines or antiviral drugs. For each scientist, we then looked for links with the pharmaceutical industry – or what we formally call competing interests - from a variety of sources, including scientific papers and the internet.

Cambridge CB2 2QQ, UK MedicalResearch.com: What is the background for your study? Dr. Menon: We have known for some time that a history of traumatic brain injury (TBI) results in a significant (between 2 and 10 fold) increase in the likelihood of getting dementia in later life.  On possible mechanistic explanation for this comes from the finding that about a third of individuals who died of TBI, regardless of age, are found at autopsy to have deposits of β-amyloid in the brain, often Aβ42, which is the same variant of amyloid seen in the brain of patients who have Alzheimer’s Disease. However, such detection after death has made it impossible to examine the linkage of such early amyloid deposition to late dementia.  More recently, imaging with positron emission tomography (PET) and Pittsburgh compound B (PIB) has been used to image amyloid deposits in Alzheimer’s  Disease.  However, the technique had not been validated in traumatic brain injury.

MedicalResearch.com Interview with: Jonas D. Finger and  Dr. Gert B.M. Mensink Jonas Finger, MPhil (Epidemiology) MA (Sports Sc) MA (Political Sc) Robert Koch-Institute - Department of Epidemiology and Health MonitoringDivision 24 - Interview surveys and European collaboration General-Pape-Straße 62-66, 12101 Berlin Germany MedicalResearch.com: What are the main findings of the study? Answer: People with a low level of education consume energy dense foods (sugar- and fat-rich foods) more frequently and low energy foods (fruit and vegetables) and alcohol less frequently compared to people with a high level of education. A new study aspect is that the role of physical activity level for the link between education and high energy food intake was also investigated. People with a low level of education have more frequently physically-demanding jobs leading to a higher level of total energy expenditure compared to sedentary office workers (mainly high educated). The latter are more active in their leisure time. The study provides some evidence to support the hypothesis that the low educated consumed more energy dense foods than the high educated because they expend more energy due to the physical work they do.
