Dr. Pinker: We hypothesized that by imaging multiple key processes involved in cancer development and growth with multiparametric PET/MRI an improved non-invasive diagnosis of breast tumors is possible. To test this hypothesis, we conducted this first clinical feasibility study.
Mutliparametric PET/MRI allows an improved non-invasive differentiation of benign and mailgnant breast tumors than currently used contrast-enhanced MRI alone. By its use unnecessary breast biopsies in benign tumors can be avoided without missing cancer.

MedicalResearch: What are the main findings of the study?Answer: St. John’s wort (SJW), a common complementary and alternative medicine (CAM) treatment for depression, is frequently used together with drugs that may interact dangerously with it. In data from the 1993-2010 National Ambulatory Medical Care Survey, a nationally representative survey of physician visits from the National Center for Health Statistics, SJW was prescribed together with drugs such as selective serotonin reuptake inhibitors (SSRIs), benzodiazepines, warfarin, statins, digoxin, verapamil, and oral contraceptives. Using SJW together with other antidepressants may cause serotonin syndrome, a potentially fatal condition.

MedicalResearch: What are the main findings of the study?Dr. Yeung: We believe that this study has bridged a significant gap in knowledge between epidemiological data (the association of obesity and poor breast cancer prognosis) and biological mechanisms mediating the impact of obesity on cancer. This study provides an important mechanistic insight into the causal relationship between obesity and breast cancer growth.
Direct evidence for the links between obesity-associated changes in the biological processes and hallmarks of cancer in human estrogen receptor-positive (ER+) breast cancer.
It is well known that obesity is associated epidemiologicaly with decreased survival in ER+ breast cancer patients. Although a body of experimental literature exists to suggest important roles for estrogen, insulin/IGF-1 and adipokine signaling and inflammation in the mechanisms mediating the impact of obesity on cancer, direct evidence for these mechanisms and their importance relative to one another is lacking in cancers from obese humans.
Functional transcriptomic analysis of a prospective observation cohort with treatment-naïve ER+ breast cancer samples identified the insulin/PI3K signaling and secretion of cytokines among the top biological processes involved. Many of the obesity-associated changes in biological processes can be linked to cancer hallmarks. Upstream regulator analysis identified estrogen (?-estradiol), insulin (INS1), insulin-like growth factor-1 (IGF1), and adipokines [vascular endothelial growth factor A (VEGFA), tissue necrosis factor (TNF), interleukin-6 (IL6), oncostatin-M (OSM), chemokine ligand 5 (CCL5), leptin (LEP), leukemia inhibitory factor (LIF), C-reactive protein (CRP), adiponectin (ADIPOQ), and interleukin-10 (IL10)] in mediating the impact of obesity on human ER+ breast cancer.
Experimental evidence that obesity causes accelerated oncogene-driven ER+ breast cancer carcinogenesis.
While it is not possible to conduct a human experiment to prospectively examine the causal relationship between obesity and breast cancer, we created a transgenic mouse model with genetically induced obesity and oncogene-driven breast cancer. With this model we found strong in vivo evidence using both longitudinal experiments and cross-sectional experiments that obesity accelerated oncogene-driven breast carcinogenesis.

MedicalResearch: What are the main findings of the study?Dr. Truninger: In our study, we investigated the effect of lifestyle exposure on DNA methylation. We measured genome-wide promoter CpG methylation in 1092 normal colon biopsies from 546 healthy females. We observed that fewer CpGs acquired age-dependent methylation in users of aspirin and hormonal replacement therapy compared with nonusers, whereas more CpGs were affected in smokers and individuals with a body mass index > 25 compared with nonsmokers and less obese females. Half of the CpGs showing age-dependent methylation gain were hypermethylated in tissue of colorectal cancer. These loci gained methylation with a higher rate and were particularly susceptible to lifestyle exposure compared to age-only methylated CpGs. In addition, these CpGs were enriched for polycomb regions. Finally, all effects were different according to the anatomic location along the colon.

Assistant Professor Transplant Surgery

Director Northwestern University Transplant Outcomes Research Collaborative (NUTORC)
Comprehensive Transplant Center
Feinberg School of Medicine, Northwestern University
MedicalResearch: What are the main findings of the study?Dr. Ladner: With the current kidney organ allocation system, there exists significant geographic disparity between the 58 Donor Services Areas (DSAs) in the US, which are distributed among 11 regions. This means that depending on where a patient lives it might take shorter or longer to receive a kidney organ for transplantation. Despite efforts, this has not improved over the course of 20 years and in most regions this has worsened. In 1991 and 1992 respectively, two states changed their kidney allocation system, such that kidneys would first be allocated with the DSA of procurement, then statewide, then regionally (which may include several states) and then nationally. Usually kidneys don’t get allocated statewide before regionally.
The main finding of this study is that in those two states (FL, TN), where a minor change to the kidney allocation was put into place, there was significant reduction in the geographic disparity between their Donor Services Areas. In other comparable states (equal numbers of DSAs within the state) the geographic disparity did not improve and in many the geographic disparity worsened. (more…)

ELS/Health Division
MedicalResearch: What are the main findings of the study?
Answer:
The United States is an outlier in the scenery of OECD as it ranks first for health care expenditure, but last for coverage.
The slowdown in US health care spending during the past decade brought the growth rate closer to that of other high-spending countries -Canada, France, Germany, the Netherlands and Switzerland- at around 1%. Previously in 2002, the US's health expenditure growth was around 7%, much higher than the approximate 3% which was the average for the other countries examined in the study
Higher health-sector prices (e.g., hospital care and prescription drugs) are thought to be the main driver of expenditure differences between the US and other high-spending countries, and recent price dynamics largely explain declines in health expenditure growth.

Ann Arbor MichiganMedicalResearch: What are the main findings of the study?Dr. Vijan:The main finding was that the burdens and side effects of intensive glycemic treatment significantly detract from the overall benefit of lower risks of diabetes complications, often to the point where the treatments cause more loss than gain in quality of life. It takes many (often 15-20) years to gain benefit from treatment, but the burdens begin right away and continue throughout treatment. By the time you might experience treatment benefit in terms of reduced complication risk, you've had a lot of years to have the downsides of treatment - which commonly include significant weight gain, low blood sugars, gastrointestinal symptoms, not to mention having to take multiple pills or injections on a daily basis.

Because of recent studies showing that tenofovir gel could reduce the chances of becoming HSV-2 infected, we studied the subset of HIV-uninfected partners who did not have HSV-2 and compared the rates who became HSV-2 infected during follow-up among those who received oral pre-exposure prophylaxis versus those who received placebo. We found that oral pre-exposure prophylaxis reduced HSV-2 acquisition by 30%.

MedicalResearch: What are the main findings of the study?Dr. Riddle: We used a classification system developed by researchers in Spain in the late 1990s and found that classifications of appropriate, inappropriate and inclusive ratings for persons undergoing knee replacement surgery were 44.0%, 21.7%, and 34.3%, respectively. We studied 175 persons who underwent unilateral total knee replacement in the Osteoarthritis Initiative study, an NIH and privately funded multi-year cohort study of persons with are at high risk for knee osteoarthritis. These findings need to be considered cautiously because the classification system was developed more than 15 years ago and was designed to place greatest priority on persons with end stage knee osteoarthritis and severe pain and functional loss.

MedicalResearch: What are the main findings of the study?Answer: We examined C-CDA (Consolidated Clinical Document Architecture) documents from electronic health records and other health information technology vendors. C-CDA documents are an XML format for transmitting patient data (e.g. problems, allergies, medications, results, vital signs, smoking status). Usage of C-CDA documents is required for Stage 2 of Meaningful Use in the United States. Overall, we were readily able to extract data elements from these documents, but we found many places where clinical content could be improved. This leads to policy recommendations on improving C-CDA production and consumption. Since thousands of hospitals and many more physicians will be required to exchange these documents in the coming year, we believe our findings to be important and timely for those seeking to improve care continuity and information exchange.

MedicalResearch.com Interview with: Dr. John A. Copland, PhD
Associate Professor of Biochemistry/Molecular Biology
Professor of Cancer Biology

Mayo Clinic, Jacksonville, Florida
MedicalResearch: What are the main findings of the study?Dr. Copland: In our study we identified a pro-cancerous role for a novel protein- neuronal pentraxin 2 (NPTX2). This protein, normally found expressed in brain and nervous system tissues, is highly overexpressed in kidney tumors at all stages of disease. It has never previously been associated with kidney cancer, nor has it been associated with an oncogenic function in any other cancer. NPTX2 appears to play a significant role in not only tumor cell survival, but it also promotes tumor cell migration through activation of the ionotropic glutamate receptor 4 (GluR4). GluR4, also commonly associated with nervous system tissues, appears to be manipulating the flow of calcium into the tumor cell. Both NPTX2 and GluR4 are not components of normal kidney cell function. Because calcium is an important co-factor for many signaling pathways controlling cell growth, survival, and mobility, unconstrained calcium levels in a cell can promote malignancy. We show that calcium calmodulin kinase and AKT, two oncogenic signaling pathways are activated by NPTX2 via calcium influx.

MedicalResearch: What are the main findings of the study?Answer: This is the first report demonstrating that selective phosphodiesterase enzyme (PDE) 4 inhibitor roflumilast added to metformin (MET) was superior to metformin alone in reducing mean body weight after 12 weeks of treatment in obese women with polycystic ovary syndrome (PCOS), primarily due to a loss of fat mass.
31 women with PCOS diagnosed by the National Institute of Child Health and Human Development criteria aged 33.8 ± 7.4 years with BMI 36.4 ± 5.1 kg/m2concluded the study. They were randomized to MET 1000 mg BID or combined treatment (COM) with MET 1000 mg BID and roflumilast 500 mcg QD. The primary outcome were changes in anthropometric measures of obesity.
At study endpoint subjects treated with COM lost on average 4.2 ± 2.8 kg compared to a 0.9± 2.5 kg weight gain in METgroup (p<0.001). BMI decreased for 1.6 ± 1.1 kg/m2 in COM arm compared to increase for 0.9 ± 2.4 kg/m2 in MET arm (p= 0.001). Total body fat decreased for 0.7±0.4 % in COM as opposed to 0.2 ± 0.1 % increase in MET and visceral adipose tissue (VAT) area as assessed by DXA decreased for 15.5 ± 1.6 cm2 in COM as opposed to 11.4 ± 5.3 cm2 increase in MET. The greater waist circumference reduction was noted in COM (4.2 ± 1 cm) compared with MET (0.8 ± 0.7 cm). The improvements of obesity measures were associated with beneficial effects on fasting glucose levels, insulin resistance and resolution of metabolic syndrome in affected women.
The hypothesis behind the weight decrease and beneficial metabolic impact observed with roflumilast is based on the PDE4 regulation of signaling pathways linked to GLP-1 release. In experimental rodent model a single treatment with roflumilast enhanced plasma GLP-1 levels up to 2.5 -fold.

Professor of Pediatrics - Neonatology
University of Iowa Carver College of Medicine
MedicalResearch: What are the main findings of the study?Dr. Morriss: Our aim was to assess the association between surgery performed during the initial hospitalization of very low- birth-weight infants and subsequent death or neurodevelopmental impairment at 18-22 months’ corrected age. We conducted a retrospective cohort analysis of patients who were prospectively enrolled in the National Institute of Child Health and Human Development Neonatal Research Network Generic Database from 1998 to 2009. Surgery was classified by the expected anesthesia type as either major surgery that likely would have been performed under general anesthesia; or minor surgery, that is, procedures that could have been performed under non-general anesthesia and in general were shorter in duration. There were 2,186 major surgery patients and 784 minor surgery patients and more than 9,000 patients who did not undergo surgery.
We found that any surgical procedure increased the adjusted risk of death or neurodevelopmental impairment in low birth weight infants by about 30%. Not all surgical procedures were associated with increased risk, however. Compared with those who did not undergo surgery, patients who were classified as having major surgery had a risk-adjusted odds ratio of death or neurodevelopmental impairment of 1.52 (95% confidence interval 1.24-1.87). However, those who were classified as having minor surgery had no increased adjusted risk. Among survivors who had major surgery compared with those who did not undergo surgery the risk-adjusted odds ratio for neurodevelopmental impairment was 1.56 (95% confidence interval 1.26-1.93), and the risk-adjusted mean Bayley II Mental Developmental Index and mean Psychomotor Developmental Index values were significantly lower.

MedicalResearch: What are the main findings of the study?Answer: Keloid is a long-term dermatological scarring disease characterized by disfiguring lesions resulting from overgrowth of dense fibrous tissue. It is also unsightly and can even lead to disfigurement and psychological problems of affected patients. This study investigated the use of microneedle technology in the self-management of keloid lesions. Briefly, we have developed a “wearable” microneedle device for transdermal delivery of an anti-metabolite drug (5-FU) to inhibit the proliferation activity of keloid fibroblast. This study has provided evidence for effective inhibition of keloid fibroblasts in vitro and successful translation of this platform can significantly reduce the cost of keloid treatment and improve the patient compliance.

Medical University of South Carolina Stroke Center
The Center of Rehabilitation Research in Neurological Conditions
MedicalResearch: What are the main findings of the study?Dr. Feng: Stroke hospitalization rate is decreasing in the elderly, but increasing in the young/middle aged population, but this increase is mainly driven by the increase in blacks (not in whites) which incurred persistent racial disparity in stroke. It has tremendous economic impact as outlined in the paper. Of hospital charges totaling $2.8 billion over 10-year period, $453.2 million (16.4%) are associated with racial disparity (79.6% from patients <65 years).
By way of background:
84,179 stroke hospitalizations occurred in South Carolina from 2001 to 2010. Blacks accounted for 29,846 (35.5%) and whites accounted for 54,333 (64.5%) of the strokes. Among blacks, 50.4% were <65 years of age compared to 29.6% among whites. The overall stroke hospitalization rate decreased over the 10-year period. There was a significant reduction in stroke hospitalization rate in the older (≥65 years old) populations, for both blacks and whites.
Whereas, in the younger populations (<65 years old), the overall rate of stroke hospitalizations actually increased significantly; however this increase was only associated with black patients. For example, the hospitalization rate per 100,000 for young blacks was 121 in 2001, 139 in 2005 and 142 in 2010 (a 17.3% increase from 2001).
This racial disparity was more severe in the younger group with the highest disparity seen in the 45-54 year age groups for both ischemic strokes (having a clot) and intra-cerebral hemorrhagic strokes.
