What are the main findings? Response: The initial observation was that daily practice of mammography shows a substantial proportion of women that report a negative experience after having a mammogram. Compression of the breast before delivering X-rays is mandatory to achieve the best image quality and to detect small cancers. Unfortunately, compression is uncomfortable, even sometimes painful. We took into consideration a study of PJ Kornguth et al. published in 1993 reporting the self-compression technique. In this study one breast was compressed by the radiographer and the other with self-compression. The author reported a high level of patient satisfaction, and a lower discomfort, without compromising image quality. We performed a multicenter prospective randomized trial to demonstrate the feasibility of the self-compression technique in condition similar to routine screening or follow-up, compared with standard compression. The primary outcome was to demonstrate that self-compression did not lead to compress the breast less than standard compression, and that was done. The secondary outcomes were to evaluate pain, compression force and image quality. The results indicated that compression force was higher when the women controlled themselves the compression of their breast, and the pain measured on a visual analogue scale was lower. Moreover, image quality was not compromised compared with standard compression.  (more…)

MedicalResearch.com Interview with: Dr Sarah Hall PhD Senior Lecturer in Forensic Science Anglia Ruskin University MedicalResearch.com: What is the background for this study? Response: We initially started the study in collaboration with Essex Fire and Rescue Services, as we were already doing some research on the recovery of evidence from fire scenes. During a visit to their cold fire scene facility, they described a tragic fatality with extensive fire damage, which didn’t link with the main fuel in the room. Therefore they questioned if a skin cream, regularly used by the victim, could have contributed as a fuel or ignited to initiate the fire and asked if we would do some initial research. Now we are also working with West Yorkshire and Cambridgeshire Fire and Rescue Service, the London Fire Brigade, St Andrews Centre for Plastic Surgery and Burns and the National Fire Chiefs Council.

Author Interviews, Diabetes, Education, JAMA, Pediatrics / 06.02.2019

MedicalResearch.com Interview with: Niels Skipper PhD Associate Professor, Department of Economics and Business Economics Aarhus University MedicalResearch.com: What is the background for this study? What are the main findings? Response: It is unclear if there is an association between type 1 diabetes and school performance in children. Some studies have found type 1 diabetes to be associated with worse performance, while others have found no differences. However, most of the existing literature are based on smaller, non-random samples of children with diabetes. In this study we used data on all public school children in the country of Denmark, involving more than 600,000 schoolchildren where approximately 2,000 had a confirmed diagnosis of type 1 diabetes. The children were tested in math and reading using a nationally standardized testing procedure, and we found no difference in the obtain test scores between children with diabetes compared to children without diabetes.  (more…)

MedicalResearch.com Interview with: Heather Hsu, MD MPH Assistant Professor of Pediatrics Boston University School of Medicine Boston Medical Center Boston, MA 02118 MedicalResearch.com: What is the background for this study? What are the main findings?  Response: In October 2013, the Centers for Medicare and Medicaid Services (CMS) implemented value-based incentive programs to financially reward or penalize hospitals based on quality metrics. Two of these programs – Hospital Value Based Purchasing and the Hospital Acquired Condition Reduction Program – began targeting hospitals’ rates of certain healthcare-associated infections deemed to be preventable in October 2015. Previous studies demonstrated minimal impact of these value-based payment programs on other measures of hospital processes, patient experience, and mortality. However, their impact on healthcare-associated infections was unknown. Our goal was to study the association of value-based incentive program implementation with healthcare-associated infection rates, using catheter-associated urinary tract infection in intensive care units (one of the targeted outcomes) as an example. We found no evidence that federal value-based incentive programs had any measurable association with changes in catheter-associated urinary tract infection rates in the critical care units of US hospitals.

MedicalResearch.com Interview with:

Dr. Martina Callaghan PhD Head of Physics & Senior Lecturer Wellcome Centre for Human Neuroimaging Institute of Neurology University College London London

MedicalResearch.com:  What is the background for this study?  What are the main findings?

Response: As mirrors the situation in the general population, we found that an increasing number of volunteers who were seeking to enter cognitive neuroscience studies at our Centre had tattoos. However, the magnetic fields used in magnetic resonance imaging (MRI) pose a potential safety risk for people with tattoos. A number of case reports have described such incidents.  However, as these describe isolated cases retrospectively, there was not enough information to objectively assess the risk of tattoo-related adverse reactions for persons having an MRI scan.  Therefore, in 2011, we decided to embark upon this first prospective study to quantitatively assess this risk.

Author Interviews, Beth Israel Deaconess, Brigham & Women's - Harvard, Frailty, Heart Disease, Surgical Research / 05.02.2019

MedicalResearch.com Interview with: Dae Hyun Kim, MD, MPH, ScD Assistant Professor of Medicine, Harvard Medical School Hinda and Arthur Marcus Institute for Aging Research, Hebrew SeniorLife Division of Pharmacoepidemiology and Pharmacoeconomics, Department of Medicine, Brigham and Women’s Hospital Division of Gerontology, Department of Medicine, Beth Israel Deaconess Medical Center MedicalResearch.com: What is the background for this study? What are the main findings? Response: The number of older adults undergoing aortic valve replacement is increasing.  Since these patients are at high risk for complications and functional decline due to preexisting multimorbidity and frailty, the latest guideline (Otto et al. J Am Coll Cardiol 2017;69:1313–46) emphasizes shared decision-making based on patient-centered outcomes.  Despite this recommendation, we witness many decision-making processes are cardio-centric—mainly informed by expected benefit in terms of cardiac-specific measures.  Many patients are not adequately informed about what their daily life would be like after the procedure. In this single-center prospective cohort study, we examined functional status trajectories via assessments of global functional status at 1, 3, 6, 9, and 12 months in 246 patients who underwent transcatheter and surgical aortic valve replacement.  We identified 5 clinically meaningful functional trajectories, ranging from high baseline function-early complete recovery to low baseline function-large and persistent decline.  We were able to predict most likely trajectory as well as best possible and worse possible trajectories using the preoperative frailty index.  Delirium and postoperative complications were also strongly associated with undesirable functional trajectories.  (more…)
Author Interviews, JAMA, Ophthalmology, Pediatrics, STD, USPSTF / 05.02.2019

MedicalResearch.com Interview with: Michael Silverstein, M.D., M.P.H. Professor of Pediatrics Director of the Division of General Academic Pediatrics Vice chair of research for the Department of Pediatrics Boston University School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: Gonococcal ophthalmia neonatorum, or GON, is a severe infection of the eye that can occur in babies born to women who have gonorrhea. If left untreated, GON can cause serious problems, including blindness, that can appear as soon as 24 hours after delivery. Fortunately, there are effective treatments available that can prevent GON in newborns. The U.S. Preventive Services Task Force reviewed the most current research on the benefits and harms of ocular prophylaxis—which is applying antibiotic ointment to the babies’ eyes at birth—to prevent GON. We found that, if applied within 24 hours after birth, the ointment is very effective at preventing gonococcal ophthalmia neonatorum and the problems it causes. Therefore, we are recommending that clinicians provide this preventive service for all newborns.  (more…)
Author Interviews, JAMA, Thyroid, Thyroid Disease / 04.02.2019

MedicalResearch.com Interview with: Joanna Klubo-Gwiezdzinska, M.D., Ph.D., M.H.Sc. Assistant Clinical Investigator/Assistant Professor Metabolic Disease Branch/NIDDK/NIH Bethesda, MD MedicalResearch.com: What is the background for this study? What are the main findings? Response: People with intermediate- and high-risk differentiated thyroid cancer (DTC) are treated with surgical removal of the thyroid gland and radioactive iodine therapy.  After surgery and initial treatment, the thyroid hormone levothyroxine is used for long-term management not only to replace appropriate physiologic thyroid hormones post-surgery, but also to suppress thyrotropin (TSH) release from the pituitary gland at supraphysiologic doses. The current recommended American Thyroid Association TSH suppression goal in patients with a high-risk differentiated thyroid cancer presenting with distant metastases is less than 0.1mIU/ml, and between 0.1-0.5 mIU/ml for patients with intermediate-risk DTC presenting with local metastases to the neck lymph nodes. This TSH goal is much lower than physiologic TSH level, which ranges between 0.4-4.1 mIU/ml, depending on the measurement method and person’s age. TSH suppression is used because some preclinical evidence suggests that TSH can stimulate growth of cancer cells.  However, several preclinical studies show that thyroid hormones may also stimulate cancer growth. In addition, too much levothyroxine, leading to TSH suppression, may cause side effects such as abnormal heart rhythms and decreased bone mass. In this study, based on a large multicenter database analysis, we found that continuous TSH suppression with levothyroxine was not associated with better progression-free survival and overall survival in patients with either intermediate- and high-risk differentiated thyroid cancer. The patients were followed for an average of 7 years after surgical thyroid cancer removal and radioactive iodine therapy.  (more…)

MedicalResearch.com Interview with Michelle Androulakis, MD, MS, FAHS Chief of Neurology WJB Dorn VA Medical Center and Faculty at University of South Carolina. Columbia, SC MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Even though Migraine with aura was associated with an increased risk of ischemic stroke in the Atherosclerosis Risk in Communities study (ARIC), our post-hoc showed unexpected results that onset of such migraines before age 50 years is not associated with such risk. Instead, later onset of migraine with aura after age of 50 was linked with a higher risk of ischemic stroke. Total of 447 migraineurs with aura (MA) and 1128 migraineurs without aura (MO) among 11,592 participants were included in the analysis. There was a two-fold increased risk of ischemic stroke when the age of migraineurs with aura onset was 50 years or older as compared with no headache participants, MO was not associated with increased stroke risk regardless of age of onset.  (more…)

MedicalResearch.com Interview with: Vitor Engrácia Valenti, PhD Professor São Paulo State University Marília MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Autonomic modulation and cardiorespiratory variables are influenced by numerous factors. Abdominal fat tissue is a relevant variables related to metabolic and cardiovascular disorders, including diabetes mellitus, dyslipidemia and hypertension, which are associated to increased risk of morbidity and mortality. We evaluated cardiorespiratory variables and autonomic nervous system before and during recovery from exercise in healthy physically active men divided according to with waist-stature ratio (WSR): G1 – between 0.40 and 0.449 (N = 19), and G2 – between 0.45 and 0.49. This metholodigcal procedure is able to provide important information regarding the risk for developing cardiovascular disease in the future. Our main findings indicated that healthy physically active men with waist-stature ratio values close to the risk limit (between 0.449 and 0.5) presented slower return of autonomic and cardiorespiratory variables to baseline values after moderate exercise. It suggests that this group present an elevated probability of developing cardiovascular disease in the future compared to the groups with lower values of waist-stature ratio. (more…)
Antibiotic Resistance, Asthma, Author Interviews, JAMA / 04.02.2019

MedicalResearch.com Interview with: Mihaela S Stefan, MD, PhD FACP Research Scientist, Institute for Healthcare Delivery and Population Science Associate Professor, UMMS-Baystate Director of Perioperative Clinic and Medical Consultation Program Academic Hospitalist Director Quality Assessment, Division of Healthcare Quality Springfield MA MedicalResearch.com: What is the background for this study? What are the main findings? Response: In a prior study we have found that roughly 41% of patients hospitalized with an asthma exacerbation receive antibiotics although the guidelines do not support this practice. We found that the evidence supporting the guidelines was however limited to 6 trials which included a total of only 681 adults and children and most trials’ outcomes were symptoms or lung function not length of stay, need for mechanical ventilation, readmissions or death. We performed the largest observational study to-date of approximately 20 000 patients hospitalized for asthma exacerbation and found that patients treated with antibiotics did not have better outcomes but instead they had longer hospital stay and an increased risk for antibiotic-related diarrhea.

Author Interviews, Cancer Research, Global Health, Lancet, Weight Research / 04.02.2019

MedicalResearch.com Interview with: Hyuna Sung, PHD Principal Scientist, Surveillance Research American Cancer Society, Inc. 250 Williams St. Atlanta, GA 30303  MedicalResearch.com: What is the background for this study? Response: This project was motivated by our previous finding on the rise of colorectal cancer among young adults before age 55. Changes in cancer trends among young age group have significant implications because the newly introduced carcinogenic agents are likely to affect trends among young people before they affect those among older people. Owing to this relationship, cancer trends among young people can be often considered as a bellwether for future disease burden. Given the dramatic increase of the obesity prevalence during 3-4 decades in the US, we wanted to expand the colorectal cancer finding to the more comprehensive list of cancers and explain them in the context of obesity epidemic.

Author Interviews, CMAJ, Fertility, McGill, OBGYNE / 04.02.2019

MedicalResearch.com Interview with: Natalie Dayan MD MSc FRCPC General Internal Medicine and Obstetric Medicine, Clinician-Scientist, Research Institute Centre for Outcomes Research and Evaluation (CORE) McGill University Health Centre Montréal QC MedicalResearch.com: What is the background for this study? What are the main findings? Response: Infertility treatment is rising in use and has been linked with maternal and perinatal complications in pregnancy, but the extent to which it is associated with severe maternal morbidity (SMM), a composite outcome of public health importance, has been less well studied. In addition, whether the effect is due to treatment or to maternal factors is unclear. We conducted a propensity matched cohort study in Ontario between 2006 and 2012. We included 11 546 women who had an infertility-treated pregnancy and a singleton live or stillborn delivery beyond 20 weeks. Each woman exposed to infertility treatment was then matched using a propensity score to approximately 5 untreated pregnancies (n=47 553) in order to address confounding by indication. Poisson regression revealed on overall 40% increase in the risk of a composite of SMM (one of 44 previously validated indicators using ICD-10CA codes and CCI procedure codes) (30.3 per 1000 births vs. 22.8 per 1000 births, adjusted relative risk 1.39, 95% CI 1.23-1.56). When stratified according to invasive (eg., IVF) and non-invasive treatments (eg. IUI or pharmacological ovulation induction), women who were treated with IVF had an elevated risk of having any severe maternal morbidity, and of having 3 or more SMM indicators (adjusted odds ratio 2.28, 95% CI 1.56 – 3.33), when compared with untreated women, whereas women who were treated with non-invasive treatments had no increase in these risks.

MedicalResearch.com Interview with: Valentina Tonei, PhD British Academy Research Associate Department of Economics and Related Studies University of York, UK MedicalResearch.com: What is the background for this study? What are the main findings? Response: There has been a growing utilisation of Caesarean sections in the past decades. To put it in a perspective, in the United Kingdom, the caesarean section rate was about 26% in 2015, while in 1990s it was about 12-15%. A similar increase has been observed in other countries, for example in the USA. So, while this study focuses on the United Kingdom, I believe that the evidence from this research can apply also to other countries. I study the health consequences for mothers who give birth through an emergency caesarean. Thanks to previous studies, we are well-aware of the implications for mothers’ physical health; instead, this research sheds light on the impact on new mothers’ mental health. I find that new mothers who have an emergency caesarean delivery are at higher risk of developing postnatal depression in the first 9 months after the delivery.  (more…)

MedicalResearch.com Interview with: Sheri Madigan, Ph.D, R.Psych Canada Research Chair in Determinants of Child Development Assistant Professor, Department of Psychology Alberta Children's Hospital Research Institute University of Calgary MedicalResearch.com: What is the background for this study? What are the main findings? Response: Parents are reporting that screen time is one of their major concerns, so we wanted to find out more about how large of a role screen time was playing on children’s developmental outcomes. We were especially interested in the long-term impact of screens, which is why we followed children over time, from ages 2 to 5 and repeatedly assessed both screen time use and children’s achievement of developmental milestones. There are three main findings:
  1. Our study revealed that on average children were viewing screens for 2.4, 3.6 and 1.6 hours per day at two, three and five years of age, respectively. This means that the majority of the participants in our sample are exceeding the American Academy of Pediatrics’ guideline.
  2. We found statistically significant, albeit small effects suggesting that greater amounts of screen time at two and three years predict poorer child outcomes at three and five years, respectively. Thus, screen time has a lasting influence on children’s development.
  3. The opposite pattern was not observed. That is, we did not find evidence that children showing poor performance in terms of achieving developmental milestones were more likely to be place in front of screens to help cope with their potentially challenging behaviors.

To view a copy of this license, visit: https://creativecommons.org/licenses/by/2.0Dr. Qiushi Chen (first author) and Jagpreet Chhatwal PhD Assistant Professor, Harvard Medical School Senior Scientist, Institute for Technology Assessment Massachusetts General Hospital MedicalResearch.com: What is the background for this study? What are the main findings? Response: Opioid overdose epidemic is a national public health emergency — in 2017, more than 49,000 people died from overdose. Our study shows that under current conditions, the number of deaths is projected to increase to 81,700 by 2025. Efforts to curb the epidemic by reducing the incidence of prescription opioid misuse — the primary focus of current interventions — will have a modest effect of 3-5% reduction in overdose deaths.

MedicalResearch.com Interview with: Professor Sherry Towfighian PhD Mechanical Engineering Binghamton University   MedicalResearch.com: What is the background for this study? What are the main findings?  Response: We wanted to avoid using batteries in a load monitor that can be placed in total knee replacement. We looked into energy scavenging technologies and studied the most appropriate one for this application. Energy scavenging is converting wasted energy such as walking to electricity for low power sensors. Our research study showed walking can provide enough electrical energy (about 6 microwatts) for low power load sensors. These load sensors are important in providing information about the mechanical load throughout different activities. It can be used in the future to create a self -awareness device for the patient to avoid certain activities.  (more…)

MedicalResearch.com Interview with: Wenquan Zou, MD, PhD Associate Professor Departments of Pathology and Neurology Director of CJD Skin Project Associate Director National Prion Disease Pathology Surveillance Center Institute of Pathology Case Western Reserve University School of Medicine Cleveland, Ohio 44106 MedicalResearch.com: What is the background for this study? Would you briefly explain the significance of prion-induced diseases and why they have been difficult to diagnosis? Response: Our previous study has demonstrated that infectious prions are detectable in the skin samples of patients with sporadic Creutzfeldt-Jakob disease (sCJD), the most common form of human prion disease, at the terminal stage by the highly sensitive real-time quaking-induced conversion (RT-QuIC) assay and animal-based bioassay. The prion-induced diseases are significant because they are infectious diseases that can be transmitted inter-species and intra-species. For instance, mad cow disease, a prion disease in cattle, has been documented to transmit to humans. Currently, there are no cures for these fatal diseases. The definite diagnosis of prion diseases is difficult because it mainly depends on the availability of brain tissues obtained either by biopsy or autopsy for detection of prions. Brain biopsy is highly invasive and it is difficult to be accepted by patients and their families. Even for brain autopsy, it is not always feasible because of religious and cultural limitations in some regions or countries.  (more…)
Author Interviews, Diabetes, JAMA, Primary Care / 01.02.2019

MedicalResearch.com Interview with: Diane M. Gibson, Ph.D. Executive Director – New York Federal Statistical Research Data Center, Baruch RDC Associate Professor – Marxe School of Public and International Affairs, Baruch College - CUNY MedicalResearch.com: What is the background for this study? What are the main findings? Response: Prior studies have found that screening for diabetic retinopathy in primary care settings using telemedicine increased screening rates among individuals with diabetes and among subgroups of individuals with diabetes who are at high risk of missing recommended eye exams.  In a previous paper I looked at how often U.S. adults with diabetes visited primary care and eye care providers for recommended diabetes preventive care services using a sample from the 2007-2013 Medical Expenditure Panel Survey.  I found that while visits to eye care providers were often skipped, most adults with diabetes did visit primary care physicians.  I argued that these findings suggest that screening for diabetic retinopathy in primary care settings using telemedicine has the potential to fulfill unmet needs and reach most U.S. adults with diabetes. My brief report in JAMA Ophthalmology examines patterns of eye examination receipt and visits to primary care physicians among U.S. adults with diabetes using a sample from the 2016 National Health Interview Survey.  The report pays particular attention to individuals who are at high-risk of missing recommended eye exams. The study found that 87.7% of the sample of adults with diabetes visited a primary care physician in the past year and that, except for the uninsured subgroup, more than 78% of each high-risk subgroup visited a primary care provider in the past year.  (more…)

MedicalResearch.com Interview with: Silvia Alemany, PhD first author Barcelona Institute for Global Health (ISGlobal), a centre supported by "la Caixa". In collaboration with co-authors: Philip Jansen,MD, MSc and Tonya White, MD, PhD Erasmus University Medical Center, Rotterdam MedicalResearch.com: What is the background for this study? Response: Individuals affected by psychiatric disorders can demonstrate morphological brain abnormalities when compared to healthy controls. Although both genetic and environmental factors can account for these brain abnormalities, we expect that genetic susceptibility for psychiatric disorders has the greatest influence on the development of the brain. Genetic susceptibility for psychiatric disorders can be estimated at the individual level by generating polygenic risk scores. Using this methodology, genetic susceptibility to psychiatric disorders and cognition has been associated with behavior problems in childhood. These findings suggest that heritable neurobiological mechanisms are at play in very early in the course of the illnesses. (more…)

MedicalResearch.com Interview with: Laura DeFina, MD President and Chief Executive Officer Chief Science Officer The Cooper Institute MedicalResearch.com: What is the background for this study? Response: Several studies suggest that endurance athletes may be at higher risk for asymptomatic hardening of the coronary arteries.  These studies, however, have been done on small numbers of endurance athletes (ie – marathon runners) and do not show whether this increase in hardening actually leads to increase in heart attacks or death of cardiovascular disease. In our population of 21,758 generally healthy individuals (average age 52 years) who presented for a preventive medicine examination, we were able to evaluate for the presence of hardening and cardiovascular events in individuals who exercised high volumes (≥3000 MET·minutes/week or comparable to running 6 miles/hour for an hour 5 days a week) versus those exercising less.

MedicalResearch.com Interview with: Stephen Onufrak, PhD Epidemiologist, Obesity Prevention and Control Branch Division of Nutrition, Physical Activity and Obesity Centers for Disease Control and Prevention Atlanta, GA  MedicalResearch.com: What is the background for this study? Response: With more than 150 million working adults in the United States, workplaces represent a far reaching setting for chronic disease prevention and health promotion. While research suggests that workplace wellness efforts can be effective at changing health behaviors, little is known about the foods that people acquire at work. In this study, we used data from the US Department of Agriculture Food Acquisition and Purchasing Survey (FoodAPS) to investigate workplace food acquisitions among employed adults during a 7 day study period. The foods we examined included those purchased in places like cafeterias and vending machines as well as those acquired for free at meetings, social events, common areas, or shared by coworkers. They did not include foods brought from home by someone to eat at work themselves or food acquired by the employee at offsite restaurants.  (more…)

MedicalResearch.com Interview with: Dr. Scott Litofsky, MD Division of Neurological Surgery University of Missouri-Columbia School of Medicine Columbia, MO 65212  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Many patients take over-the-counter medications to held their cancers. Some of these remedies may be helpful; others are potentially harmful. Anti-oxidant medications are frequently selected by patients as they are inexpensive and available. We were approached by a high school student, Macy Williams (one of the authors) to do some research in our laboratory when she won a research scholarship (the 2016 Emperor Science Award) from Stand Up to Cancer. She worked with us several times per week doing experiments during her senior year of high school. When she graduated, we continued the work that she started. We studied effects of Vitamin D3, Melatonin, and alpha-Lipoic Acid on glioblastoma cells, a highly malignant brain tumor. We included experiments of these agents alone and in combination with Temozolomide, a chemotherapy agent used as standard of care in glioblastoma. The work was done in cultured cells, measuring growth and survival of cells. We used concentrations that could be achieved by oral intake of the drugs. We found that antioxidant medications, particularly alpha Lipoic Acid, had synergistic effects with Temozolomide – that is Temozolomide impair glioblastoma cell growth and survival better when combined with an antioxidant. The mechanism of action may be through reactive oxygen species.  (more…)
Author Interviews, Hospital Readmissions, JAMA, Nursing / 29.01.2019

MedicalResearch.com Interview with: Marianne Weiss DNSc RN READI study Principal Investigator Professor of Nursing and Wheaton Franciscan Healthcare / Sister Rosalie Klein Professor of Women’s Health Marquette University College of Nursing Milwaukee Wi, 53201-1881 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our team of researchers has been studying the association of patient readiness for discharge and readmission for several years. We have previously documented that patients who had ‘low readiness’ on our Readiness for Hospital Discharge Scale were more likely to be readmitted. In this study we added structured protocols for discharge readiness assessment and nurse actions to usual discharge care practices to determine the optimal protocol configuration to achieve improved post-discharge utilization outcomes. In our primary analysis that included patients from a broad range of patient diagnoses, we did not find a significant effect on readmission from adding any of the discharge readiness assessment protocols. The patient sample came from Magnet hospitals, known for high quality care, and the average all-cause readmission rates were low (11.3%). In patients discharged from high-readmission units (>11.3%), one of the protocols was effective in reducing the likelihood of readmission. In this protocol, the nurse obtained the patients self-report of discharge readiness to inform the nurse’s discharge readiness assessment and actions in finalizing preparations for discharge. This patient-informed discharge readiness assessment protocol produced a nearly 2 percentage point reduction in readmissions. Not unexpectedly, in lower readmission settings, we did not see a reduction in readmission; not all readmissions are preventable. In the last phase of study, we informed nurses of a cut-off score for ‘low readiness’ and added a prescription for nurse action only in cases of ‘low readiness’; this addition to the protocol added burden to the nurses’ daily work and eliminated the beneficial effects, perhaps because it limited the nurse’s attention to only a subset of patients.  (more…)
Author Interviews, Biomarkers, Johns Hopkins, NIH, Pulmonary Disease, Transplantation / 29.01.2019

MedicalResearch.com Interview with: Sean Agbor-Enoh, M.D., Ph.D. Co-Director/Staff Clinician Laboratory of Transplantation Genomics National Heart, Lung, and Blood Institute National Institutes of Health MedicalResearch.com: What is the background for this study? Response: People who receive organ transplants may develop acute or chronic rejection, in which the body’s immune system attacks the transplanted organ. While acute rejection is treatable and reversible, chronic rejection is not and remains the most common cause for organ transplant loss. Lung transplant recipients have the shortest survival rates among patients who get solid organ transplantation of any kind—only about half live past five years. This poor survival rate among lung transplant recipients is due in part to a high incidence of chronic rejection. Existing tools for detecting signs of rejection, such as biopsy, either require the removal of small amounts of lung tissue or are not sensitive enough to discern the severity of the rejection. Building upon earlier work, our research team developed a simple blood test that can detect when a newly transplanted lung is being rejected by a patient, even when no outward signs of the rejection are evident.  The test could make it possible for doctors to intervene faster to prevent or slow down so-called chronic rejection—which is severe, irreversible, and often deadly—in those first critical months after lung transplantation. This same test might also be useful for monitoring rejection in other types of organ transplants. Called the donor-derived cell-free DNA test, the experimental test begins with obtaining a few blood droplets taken from the arm of the transplant recipient. A special set of machines then sorts the DNA fragments in the blood sample, and in combination with computer analysis, determines whether the fragments are from the recipient or the donor and how many of each type are present.  Because injured or dying cells from the donor release lots of donor DNA fragments into the bloodstream compared to normal donor cells, higher amounts of donor DNA indicate a higher risk for transplant rejection in the recipient.

What are the main findings?  Response: Venezuela, as many countries in Latin America, showed substantial improvements in infant mortality rates during the last 60 years. However, the decreasing pattern might be reversing. Recent socioeconomic and political events have led to a collapse in living standards, along with a breakdown of the health system. At the same time, a strict secrecy policy has ruled public institutions, and since 2013 the Venezuelan government stopped publishing mortality statistics. This study attempts to fill this gap and estimate infant mortality using hospital and census data after 2013. The main finding is that infant mortality rates in Venezuela may have stopped decreasing and started increasing in 2009 – around the time funding for the Venezuelan health system started to be substantially reduced. By 2016, the infant mortality rate was 21.1 deaths per 1000 live births, which is 1.4 times the rate in 2008 (15.0 deaths per 1000 live births), and equivalent to the rate recorded in the late 1990s, meaning 18 years of progress may have been lost.  (more…)
