Dr. Olivia Pagani Institute of Oncology of Southern Switzerland Ospedale San Giovanni, SwitzerlandMedicalResearch.com Interview with: Dr. Olivia Pagani  Institute of Oncology of Southern Switzerland Ospedale San Giovanni, Switzerland   MedicalResearch: What are the main findings of the study? Dr. Pagani: The studies show that also in premenopausal women (as already proven in postmenopausal women), aromatase inhibitors (AIs) (in this case Exemestane) given as adjuvant treatment are more effective than Tamoxifen in women with hormone receptor positive early breast cancer who are given concomitantly ovarian suppression to lower estrogen production. The 28% improvement in disease free survival is comparable to that seen in postmenopausal women. In particular, outcomes in women who did not receive chemotherapy (43% of the entire population, 29% of whom with node positive disease) were strikingly good (<97% were breast cancer free at 5 years).

Dr. Brad Spellberg MD Associate Program Director, Internal Medicine Training Program Professor of Medicine, David Geffen School of Medicine at UCLA Division of General Internal MedicineMedicalResearch.com Interview with: Dr. Brad Spellberg MD Associate Program Director Internal Medicine Training Program Professor of Medicine, David Geffen School of Medicine at UCLA, Division of General Internal Medicine MedicalResearch: What are the main findings of the study? Dr. Spellberg:  The rates of community-onset methicillin-resistant Staphylococcus aureus (CO-MRSA) varied dramatically among academic medical centers in California, New York, Illinois and North Carolina, suggesting there is not a uniform change in the "national epidemic" of the "superbug" that has generated extensive public health concern over the past decade, according to a new study.The study surveyed hospital records of 4,171 cases of MRSA and MRSA-related infections between 2008 and 2011 in five medical centers located in Los Angeles, San Francisco, Chicago, New York City and Raleigh-Durham, NC.The rates of MRSA acquired in the community declined 57% from 2008-2011 in the Los Angeles medical center. In contrast, CO-MRSA rates tripled at the New York medical center, while the rates remained stable in San Francisco, Chicago and Raleigh-Durham. (more…)

Luke Kim, M.D., FACC, FSCAI Assistant Professor of Medicine Interventional Cardiac and Endovascular Laboratory Greenberg Division of Cardiology, Department of Medicine Weill Cornell Medical College/The New York Presbyterian HospitalMedicalResearch.com Interview with: Luke Kim, M.D., FACC, FSCAI Assistant Professor of Medicine Interventional Cardiac and Endovascular Laboratory Greenberg Division of Cardiology, Department of Medicine Weill Cornell Medical College/The New York Presbyterian Hospital MedicalResearch: What are the main findings of this study? Dr. Kim: The main findings of the study include:
  1. From 2007-2011, there was no significant change in the rate of acute MI in both male and female cohorts in U.S. . Although there was a decline in the rate of ST-elevation (STEMI) in those ≥55 years old, the rate remains steady in patients < 55 years old, especially in the female cohort after 2009.
  2. Female patients <55 years old with MI were sicker at baseline than the male counterparts with more likelihood of having diabetes, hypertension, chronic renal insufficiency, peripheral vascular disease, congestive heart failure and obesity.
  3. Female patients were more likely to present with non– STEMI vs. STEMI and more likely to develop shock complicating their MIs.
  4. Female patients are less likely to undergo coronary artery revascularization including percutaneous coronary intervention and coronary artery bypass surgery.
  5. Unadjusted risk of death was higher in female vs male (5.2% vs. 3.7%, p<0.001) along with higher incidence of stroke (0.5% vs. 0.3%, p<0.001), bleeding (4.9% vs. 3.0%, p<0.001), vascular complication (0.6% vs. 0.4%, p<0.001) and ARF (11.6% vs. 9.6%, p<0.001). After adjustment, death (OR 1.10 CI 1.04-1.17), stroke (OR 1.31 CI 1.10-1.55), bleeding (OR 1.30 CI 1.22-1.37), and vascular complications (OR 1.33 CI 1.15-1.55) were all significantly higher for female cohort.

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. (more…)

MedicalResearch.com Interview with: Frank van Hees MSc Erasmus University Medical Center Rotterdam, the Netherlands and Ann G. Zauber PhD Memorial Sloan Kettering Cancer Center, New York MedicalResearch: What are the main findings of the study? Answer: The main finding of our study is that colorectal cancer screening of individuals without previous screening is worthwhile well beyond age 75, which is the recommended age to stop screening in individuals with an adequate screening history. The exact age up to which screening should be considered in unscreened elderly depends on an individual's health status: in healthy individuals screening remains worthwhile up to age 86, whereas in individuals with a severe illness, such as heart failure, screening remains worthwhile up to age 80.

​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.

MedicalResearch.com: What are the main findings of the study? Dr. Wildeman: There are four key findings in the study. First, the cumulative risk of having a confirmed maltreatment report any time between birth and age 18 is much higher than most people would have thought. Fully 1 in 8 American children will experience this event at some point. Second, the risk of experiencing this event is highly unequally distributed, with Black and Hispanic experiencing it much more than Hispanic, White, and (especially) Asian children. Between 1 in 4 and 1 in 5 Black children will have a confirmed maltreatment report at any time in their childhood. For Native American, the risk is about 1 in 7. Third, the risk of maltreatment is quite similar for boys and girls. Finally, the highest risks of child maltreatment are in the first few years of life, suggesting that interventions aiming to diminish maltreatment should focus on parents with very young children.

MedicalResearch.com Interview with : Dr. Francesco FiorentinoMedicalResearch.com Interview with : Dr. Francesco Fiorentino CEO and Lab Director ROME - ITALY MedicalResearch: What are the main findings of the study? Dr. Fiorentino: This study describes findings from first and second of a three-phase strategy to validate the use of next-generation sequencing (NGS) for comprehensive aneuploidy screening, as a preclinical step toward its routine use in the diagnosis of chromosomal aneuploidy on embryos. The first phase  involved a large preclinical validation study on single cells, and demonstrated that the NGS-based 24-aneuploidy screening protocol was accurate and reliable. The results provided 100% consistency for aneuploid embryo call with array-CGH, the highly validated method of aneuploidy screening. The second phase of the study, instead, focused on the clinical application of the NGS-based protocol for the detection of all chromosomes in embryos. A prospective trial involving analysis of human embryos at the blastocyst stage of development was designed for this purpose, in order to establish similar levels of chromosome-specific NGS copy number assignment concordance compared with 24sure array as those observed in the first phase of the study. Consistency of NGS-based aneuploidy detection was assessed matching the results obtained with array-CGH–based diagnoses, Embryos obtained from 55 consecutive clinical PGS cycles, blindly assessed in parallel with both NGS and array-CGH techniques, displayed 100% concordance for aneuploid embryo call. Consistency obtained during this investigation was similar to those obtained in the first phase of the study that used NGS to examine single cell samples, demonstrating the reliability of the NGS-based method in detection of chromosome aneuploidy also in embryos at blastocyst stage derived from clinical preimplantation genetic screening (PGS)  cycles. The clinical outcomes obtained in this study from preimplantation genetic screening cycles performed with the NGS approach were very encouraging, resulting in a clinical pregnancy rate per embryo transfer of 63.8% (mean age 38.5+2.1 years) and an ongoing implantation rate of 64.0%, values that are comparable with recent results from other comprehensive chromosome screening approaches. In conclusion, the results achieved in this study demonstrate the reliability of the NGS-based protocol for detection of whole chromosome aneuploidies, mosaicism occurrences and segmental changes in embryos.

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. (more…)

Dr. Sherman:
  • It has long been known that poverty is associated with adverse health conditions. In general, increasing poverty results in higher disease rates and higher mortality.
  • This study assessed the relationship between poverty and cancer incidence using national cancer data on nearly 3 million tumors from the North American Association of Central Cancer Registries (NAACCR).
  • Cancer registries do not collect economic information on cancer patients, so we used an area-based social measure: % of persons living below poverty within a census tract. This measure is a proxy for an individual’s economic status and also gives insight into the type of neighborhood in which an individual lives.

Answer: Commercially available automated screening devices assess refractive risk factors, not amblyopia or strabismus, resulting in under-referral of affected children and over-referral of healthy children to pediatric eye care professionals. The Pediatric Vision Scanner is a binocular retinal birefringence scanner that directly detects strabismus and amblyopia by analyzing binocular scans for the presence or absence of birefringence, which is characteristic of steady, bifoveal fixation. We found that the Pediatric Vision Scanner outperformed an automated, refractive error screener (SureSight Autorefractor) in a cohort of 300 patients (2-6 years) tested in a pediatric ophthalmology setting. Compared to the SureSight, the Pediatric Vision Scanner had significantly higher sensitivity and higher specificity in the detection of strabismus and amblyopia. (more…)

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). (more…)

Dr. Wilding: This trial studied over 3700 obese people who were trying to lose weight. The main findings were that liraglutide (an injectable medication already approved for diabetes treatment at lower dose of 1.8mg) can help reduce body weight in people with obesity when used at a higher dose than is usually used in diabetes (3mg). Trial participants experienced a weight loss of 8 % from baseline compared to 2.6 % with placebo (diet and exercise alone). Some risk factors for diabetes and heart disease such as blood sugar, blood pressure and cholesterol also improved with liraglutide treatment to a greater extent than with placebo. The main side effects seen were nausea which in most cases resolved after a few weeks treatment; there were also more cases of gallstones (which could be due to weight loss) and a few more cases of acute pancreatitis in people treated with liraglutide.

For example, 27% of advertisements mentioned a benefit of advertised services and 2% quantified these benefits.  2% mentioned a risk of advertised services and no advertisements quantified these risks.  5% mentioned costs or insurance coverage and no advertisements mentioned availability under specific insurance plans.  In contrast, use of emotional appeals was frequent (85%).  Emotional appeals commonly evoked hope for survival, focused on treatment advances, used fighting language, and/or evoked fear.  Nearly half of all advertisements included patient testimonials, overwhelmingly focused on stories about survival or cure.  Only 15% of testimonials included a disclaimer (for example, “most patients do not experience these results”) and none described the outcome that a typical patient may expect.

MedicalResearch Interview with: Dr. Valeria Pechtner Medical Advisor, Lilly Diabetes MedicalResearch: What are the main findings of the study? Dr. Pechtner: Used as monotherapy, once-weekly dulaglutide resulted in significant, sustained glycemic lowering, as measured by HbA1c change from baseline. Both the 1.5 mg and the 0.75 mg dose were superior to metformin at the primary endpoint of 26 weeks. At 52 weeks, dulaglutide 1.5 mg continued to demonstrate superiority to metformin, with dulaglutide 0.75 mg showing non-inferiority. In addition, a majority of patients in all arms achieved the American Diabetes Association’s recommended HbA1c target of less than 7 percent, with more patients achieving this goal in the dulaglutide groups at the 26-week endpoint, and more patients achieving the target in the dulaglutide 1.5 mg group at the 52 week timepoint. Additionally, dulaglutide 1.5 mg and metformin resulted in similar weight loss. The tolerability and safety profile was comparable for both medications. (more…)

Anna Philpott, Ph.D. University of Cambridge, Department of Oncology, Hutchison/MRC Research Centre, Hills Road Cambridge UK MedicalResearch.com Interview with: Anna Philpott, Ph.D. University of Cambridge, Department of Oncology, Hutchison/MRC Research Centre, Hills Road Cambridge UK MedicalResearch: What are the main findings of the study? Dr. Philpott: A group of proteins known as transcription factors that control gene expression regulate production and maturation of nerve cells during embryonic development. Recently, it was found that by adding these proteins to skin cells, they can be reprogrammed to produce nerves, which can then be used to model human conditions such as Parkinsons Disease and Alzheimers. These cells are known as induced neurons, or iN cells. However, this method generates a low number of cells, and those that are produced are not fully functional, which is a requirement in order to be useful models of disease: for example, cortical neurons for stroke, or motor neurons for motor neuron disease.  When cells are dividing, we found that transcription factors are modified by the addition of phosphate molecules, a process known as phosphorylation, and this can limit how well cells convert to mature nerves. By engineering proteins that cannot be modified by phosphate and adding them to human cells, we found we could produce nerve cells that were significantly more mature, and therefore more useful as models for disease such as Alzeheimers and Parkinsons.

Dr. Kubo: The main findings of the study are three folds: 1)  The CDC guideline works for the majority of infants in preventing vertical transmission, if the immunizations are done according to the recommended schedule. 2) It takes an organized effort to case-manage each mother-infant pairs in order to achieve almost complete immunization rates and very low transmission rates. 3) Highest risk group was mothers with extremely high viral load and e-antigen positivity.  This group of women may benefit from additional therapy to prevent the vertical transmission. However, for others, the risk of transmission is extremely low as long as the infants are immunized according to the guideline. (more…)
