Kelly K. Hunt, MD F.A.C.S. Professor, Department of Surgical Oncology, Division of Surgery Chief, Breast Surgical Oncology Section, Department of Surgical Oncology, The University of Texas MD Anderson Cancer Center, Houston, TXMedicalResearch.com Interview with: Kelly K. Hunt, MD F.A.C.S. Professor, Department of Surgical Oncology, Division of Surgery Chief, Breast Surgical Oncology Section, Department of Surgical Oncology, The University of Texas MD Anderson Cancer Center, Houston, TX MedicalResearch.com: What are the main findings of the study? Dr. Hunt: We found that 40% of women who had node positive disease at initial presentation (confirmed by needle biopsy) had no evidence of residual cancer in the lymph nodes after chemotherapy. We performed sentinel lymph node (SLN) surgery followed by axillary lymph node dissection in all of the patients and found a false negative rate of 12.6% with the SLN procedure. The false negative rate was lower when surgeons used two mapping agents (blue dye and radioisotope) to identify the sentinel nodes and when they removed more than 2 sentinel nodes. (more…)

Anthony Harris, MD, MPH Department of Epidemiology and Public Health Professor University of Maryland School of Medicine Acting Medical Director of Infection Control University of Maryland Medical CenterMedicalResearch.com Interview with: Anthony Harris, MD, MPH Department of Epidemiology and Public Health Professor University of Maryland School of Medicine Acting Medical Director of Infection Control University of Maryland Medical Center     MedicalResearch.com: What are the main findings of the study? Dr. Harris: The aim of the study was to understand if wearing disposable gowns and gloves for all patient contact in the ICU could help prevent the spread of MRSA and similar antibiotic-resistant bacteria. Secondarily we wanted to make sure this type of patient isolation did not result in any harm to patients. The results of the study were that gowns and gloves worn by healthcare workers for contact with all patients in the ICU did not decrease the number of patients who acquired VRE but did decrease MRSA about 40 percent.  Also, wearing gloves and gowns did not adversely impact patient care.  For our goal of studying all types of infection, we did not find a benefit to universal gown and glove use. However, for transmission of MRSA alone, the intervention decreased transmission by about 40 percent. Although previous studies have showed isolation is associated with falls, bed sores and other adverse events, we found gowns and gloves did not produce more of these negative events. (more…)

Dr. Sengupta: In this study we looked at all full-term neonates, which are defined as those born between 37 weeks 0 days to 41 weeks 6 days. Early term deliveries (37–38 weeks) are a significant part of all full-term deliveries, but are not the norm. In our study, 27% of neonates were born early term (37-38 weeks) while almost 62% were born at or after 39 weeks (term neonates). Similar data has been reported by other established sources of vital statistics. While traditionally, full term neonates are perceived to be a homogenous low-risk group, the findings from our study urge the pediatrics/neonatal provider to recognize early term (37-38 weeks) neonates as a higher risk group. They have significantly higher risk of NICU admission, respiratory morbidity, hypoglycemia, need for IV fluids and antibiotics. (more…)

Dr. Hauck: We looked at data from the Infant Feeding Practices Study II, which followed mother from pregnancy through the first year of infant life. Mothers received several surveys that asked about infant feeding and bedsharing (sleeping with their infant in the same bed or other sleep surface). We found that mothers who bedshared for the longest time had the longest duration of breastfeeding compared with mothers who did not bedshare or bedshared for shorter times. Breastfeeding duration was also longer among mothers who were better educated, were white, had previously breastfed another child, had planned to breastfeed this baby, and had not returned to work in the first year after the baby was born.

DeBakey Veterans Affairs Medical Center Houston, Texas 77030 MedicalResearch.com: What are the main findings of the study? Dr. Petersen: VA physicians randomized to the individual incentive group were more likely than controls to improve their treatment of hypertension.  The adjusted changes over the study period in Veterans meeting the combined BP/appropriate response measure were 8.8 percentage points for the individual-level, 3.7 for the practice-level, 5.5 for the combined, and 0.47 for the control groups.  Therefore, a physician in the individual group caring for 1000 patients with hypertension would have about 84 additional patients achieving blood pressure control or appropriate response after 1 year.  The effect of the incentive was not sustained after the washout period. Although performance did not decline to pre-intervention levels, the decline was significant.  None of the incentives resulted in increased incidence of hypotension compared with controls.  While the use of guideline-recommended medications increased significantly over the course of the study in the intervention groups, there was no significant change compared to the control group.  The mean individual incentive earnings over the study represented approximately 1.6% of a physician’s salary, assuming a mean salary of $168,000.

Dr. Taveras: The main findings of the study were that, overall, the body mass index of children in the intervention group dropped an average of 0.18, while it rose 0.21 in the control group. Children in the intervention group were sleeping about 45 minutes longer than children in the control group. Time spent watching television on weekends dropped about an hour per day in the intervention group, leading to a significant difference from the control group, which increased weekend TV viewing. Both groups had a small reduction in weekday TV viewing, with a greater decrease in the intervention group, as well. (more…)

Huynh, MD, MSHS Clinical Instructor UCLA Division of Pulmonary Critical Care MedicalResearch.com: What are the main findings of the study? Dr. Huynh: Our study shows that it is common for ICU doctors to recognize that futile treatment is provided to patients who cannot benefit from it.  In our study, 11% of ICU patients were perceived as receiving futile treatment.  The outcomes of these 123 patients were uniformly poor, with 85% dying within 6 months.  Advances in critical care medicine has allowed us to save lives, but it has also allowed us provide aggressive life-sustaining treatments that may not benefit all patients.  When aggressive treatment is poorly matched with a patient’s prognosis, doctors will consider such treatment as futile and our study shows that this is not an uncommon occurrence in our health system.

Dr. Sanderson: There is substantial variability in the interpretation of a DNR order. 66.9% of clinicians believed that a DNR order indicates limitation of resuscitative measures only on cardiopulmonary arrest, whereas 33.1% considered a DNR order to be the threshold for the limitation of treatments not specifically related to resuscitation. 68.7% of clinicians reported that the care of a patient changes once a DNR order is written. Of those reporting changes in care, 11.2% reported that this happens only if a cardiopulmonary arrest occurs, while 36.7% believed that there is an increased attention to comfort. Finally, 52.1% reported that care changes beyond both resuscitative measures and focusing on comfort, including limitation or withdrawal of diagnostic and therapeutic interventions. Most clinicians reported that resuscitation status discussions happen later in the illness course than is ideal. (more…)

McMahon, MB, BCh Renal Division, Department of Medicine, Brigham and Women’s Hospital, Harvard Medical School, Boston, Massachusetts Framingham Heart Study, National Heart, Lung, and Blood Institute, and Center for Population Studies, Framingham, Massachusetts MedicalResearch.com: What are the main findings of the study? Answer: This study examined the incidence, causes and outcomes of rhabdomyolysis in two large University Teaching hospitals. Rhabdomyolysis is a characterized by an increase in serum creatine phosphokinase (CPK) and results from muscle damage from a variety of causes. The most important complication of rhabdomyolysis is acute kidney injury which can result in a need for dialysis. Using a series of laboratory and clinical variables that are readily available on admission, we constructed a risk score that can predict with some accuracy the likelihood that a patient with rhabdomyolysis might die or need dialysis during an admission. The final variables included in the model were age, gender, the cause of rhabdomyolysis and the admission CPK, creatinine, phosphate, bicarbonate and calcium. One of the advantages of this study was, because we had access to data from two institutions, we were able to derive the risk score in one hospital and confirm its accuracy in the second institution.

Schaeffer Center for Health Policy and Economics, University of Southern California, Los AngelesMedicalResearch.com Interview with: Seth A. Seabury, PhD Department of Emergency Medicine, University of Southern California, Los Angeles Leonard D. Schaeffer Center for Health Policy and Economics, University of Southern California, Los Angeles   MedicalResearch.com: What are the main findings of the study? Dr. Seabury: We studied the trends in the earnings of male and female physicians in the US from 1987-2010 using nationally representative data from the Current Population Survey (CPS).  We found that, while the number of female physicians grew significantly, male physicians continue to have significantly higher earnings than female physicians.  The difference in the median earnings of male physicians compared to female physicians actually increased from $33,840 in 1987-1990 to $56,019 in 2006-2010, though the difference across years was not statistically significant.  Our approach controlled for differences in hours worked, so earnings gap was not driven by differences in work hours, though it could be explained by other factors we did not observe in our data (e.g., specialty choice). Looking at other occupations in the US health care industry, the male-female earnings gap was smaller for pharmacists and registered nurses and decreased over time, but was large and increased for physicians assistants.  On the other hand, our numbers indicate that outside of the health care industry, the male-female earnings gap fell by more than 45%.  Even though significant gender inequality persists across the US, female physicians do not appear to have benefited from the relative gains that female workers outside the health care industry have.

  1. The original idea set in early 20th century that psychiatric patients discharged from mental hospitals had a shortened life span or faced early death was supported by this analysis of psychiatric patients participating in research trials for new medications.  There was no increased risk of early death or shortened life span for participating in these research clinical trials. 
  2. Life span shortening or increased risk of early death is highest among patients with schizophrenia, followed by patients with major mood disorders such as Bipolar Mood Disorder and Major Depression. (more…)

Answer: We tested the hypothesis that late-onset Alzheimer disease (AD) might be in part explained by the homozygosity of unknown loci. In a genome-wide study of a Caribbean Hispanic population with noticeable inbreeding and high risk of AD we assessed the presence of long runs of homozygosity (ROHs) – regions where the alleles inherited from both parents are identical. Our results suggest the existence of recessive AD loci, since the mean length of the ROH per person was significantly longer in AD cases versus controls, and this association was stronger in familial AD.

Dr. Jaffe: In 2001, we set out to improve blood pressure control in among Kaiser Permanente (KP) members in Northern California, and we ended up creating one of the largest, community-based hypertension programs in the nation. The paper published in JAMA explores how we combined a number of innovations, including a patient registry, single-pill combination therapy drugs and more, to nearly double blood pressure control rates. If you had told us at the onset that blood pressure control among members would be more than 80 percent, and it was actually almost 90 percent in 2011, we wouldn’t have believed you. These results are truly incredible. During the study period, hypertension control increased by more than 35 percent from 43.6 percent to 80.4 percent in Kaiser Permanente Northern California between 2001 and 2009. In contrast, the national mean control rate increased from 55.4 percent to 64.1 percent during that period. (more…)
