MedicalResearch.com Interview with: Christina Mangurian, MD MAS Professor Department of Psychiatry, Weill Institute for Neurosciences Center for Vulnerable Populations, University of California, San Francisco Veronica Yank, MD Assistant Professor Division of General Internal Medicine Department of Medicine University of California San Francisco MedicalResearch.com: What is the background for this study? Response: This article is about the behavioral health and burnout consequences among physician mothers who are caring for seriously ill loved ones. Our work was inspired, in part, by some of the authors’ own experiences caring for loved ones with serious illnesses while also being physician mothers themselves.  We sought to determine the proportion of physician mothers with such caregiving responsibilities beyond their patients and children and the how these additional responsibilities affected the women’s health and practice.

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…)
Author Interviews, Cancer, Cancer Research, Supplements / 30.01.2019

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…)

MedicalResearch.com Interview with: Dr. Dawn Wiest, 7-day pledge after hospital admissionDawn Wiest, PhD Director, Action Research & Evaluation Camden Coalition of Healthcare Providers MedicalResearch.com: What is the background for this study? Response: Understanding the role of care transitions after hospitalization in reducing avoidable readmissions, the Camden Coalition launched the 7-Day Pledge in 2014 in partnership with primary care practices in Camden, NJ to address patient and provider barriers to timely post-discharge primary care follow-up. To evaluate whether our program was associated with lower hospital readmissions, we used all-payer hospital claims data from five regional health systems. We compared readmissions for patients who had a primary care follow-up within seven days with similar patients who had a later or no follow-up using propensity score matching. (more…)

MedicalResearch.com Interview with: Sean Dickson, JD MPH Officer, Drug Spending Research Initiative The Pew Charitable Trusts Washington, DC 20004 MedicalResearch.com: What is the background for this study? Response: Price increases on existing drugs are an ongoing challenge for patients and insurers, including government programs like Medicaid and Medicare. The Medicaid program requires drug manufacturers to provide a rebate that offsets price increases greater than inflation, but that rebate is capped once price increases exceed 433 percent above inflation. When these rebates are capped, manufacturers may find it more profitable to take very large price increases, raising costs for all payers. The Medicaid program has proposed removing the cap, and this study considers the effects of that proposal.  (more…)

MedicalResearch.com Interview with: Chiyori Haga, R.N. P.H.N Ph.D Department of Community Nursing Graduate School of Health Science Okayama University in Japan MedicalResearch.com: What is the background for this study? What are the main findings? Response: In Japan, we have a health checkup system for middle and elderly people to prevent their non-communicable diseases (NCDs) including the Metabolic Syndrome (MetS) and give them some health guidance based a guideline. The guideline has suggested that short duration between bed time and dinner time will be a risk factor of metabolic syndrome or diabetes mellitus for some duration. However, there may be no association between them, it is the main findings.  (more…)
Author Interviews, BMJ, Orthopedics / 28.01.2019

MedicalResearch.com Interview with: Tero Kortekangas, MD, PhD Orthopaedic trauma surgeon Oulu University Hospital Oulu, Finland MedicalResearch.com: What is the background for this study? What are the main findings? Response: Isolated, stable, Weber B type fibula fracture is by far the most common type of ankle fracture. Traditionally these fractures are treated with below the knee cast for six weeks. Although the clinical outcome of this treatment strategy has been shown to be generally favourable, prolonged cast immobilisation is associated with increased risk of adverse effects, prompting attempts to streamline the treatment. However, perhaps because of absence of high quality evidence on the effectiveness and safety of more simple non-operative treatment strategies, the current tenet of six weeks of cast immobilisation still remains the “gold standard” treatment of stable Weber B type fractures.

Author Interviews, Heart Disease, JAMA, Thyroid Disease, Vanderbilt / 27.01.2019

MedicalResearch.com Interview with: Joe-Elie Salem, MD, PhD Associate Professor - MCU-PH, Sorbonne Université - INSERM - CIC, Clinical Pharmacology, Cardio-oncology, APHP, La Pitié-Salpêtrière, Paris, France Adjunct Associate Professor, Vanderbilt University Medical Center, Cardio-oncology Clinical Pharmacology, Nashville, TN MedicalResearch.com: What is the background for this study? What are the main findings? Response: A study by researchers at Vanderbilt University Medical Center has strengthened the link between thyroid function and atrial fibrillation (AF), an irregular heart rhythm that increases the risk of stroke and other heart-related complications. They phenome-wide association study scanned the medical records of more than 37,000 people for an association between genetically determined variation in thyroid stimulating hormone levels (a measure of thyroid function) and AF risk. Previous observational studies have found that subclinical hyperthyroidism, an overactive thyroid which does not meet the clinical threshold for diagnosis or treatment, nevertheless can increase the risk of atrial fibrillation.  But whether to treat subclinical hypo- or hyperthyroidism to reduce AF risk remains a matter of debate in the medical community.  (more…)
Alzheimer's - Dementia, Author Interviews / 27.01.2019

MedicalResearch.com Interview with: Dr. Paul Harch MD Clinical Professor and Director of Hyperbaric Medicine LSU Health New Orleans School of Medicine MedicalResearch.com: What is the background for this study? Response: The background is a 30 year clinical experience and investigation in which I explored the effects of low-pressure hyperbaric oxygen therapy (HBOT) on acute, subacute, and chronic neurological conditions. Beginning with brain-injured Louisiana boxers and commercial divers in the late 1980s I attempted to see if patients with central nervous system disorders could respond to a lower dosing of the drug hyperbaric oxygen therapy than was traditionally used for other wound conditions like diabetic foot wounds, radiation wounds, and decompression sickness (the "bends").  I was successful with the very first cases after which I expanded this treatment to nearly 90 neurological conditions.  The very first patient was a boxer 23 years after his last bout who was formally diagnosed with dementia pugulistica (dementia from boxing). Since that time I have treated over 100 patients with cognitive decline or dementia, including 11 Alzheimer's cases.  Nearly all of the Alzheimer's and other dementia cases were documented with high-resolution brain blood flow imaging (SPECT).  The present case report was the first Alzheimer's case that I was able to document with PET metabolic imaging.

MedicalResearch.com Interview with: Dr. Ann Raldow MD MPH Assistant Professor Department of Radiation Oncology David Geffen School of Medicine UCLA  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Similar to women in other historically male-dominated fields, female radiation oncologists face unique obstacles in achieving many metrics of career success, including equal salary, research funding, and academic promotion. Our study of industry payments found that female radiation oncologists were less likely than their male colleagues to receive payments from industry and that these payments tended to be of smaller monetary value.

Yet, we also have plenty of anecdotal reports of adults falling asleep faster when in a train or a car, as well as a feeling of relaxation in a hammock. Our companion paper on mice (Kompotis et a., 2019 – same issue in Current Biology) clearly established that the beneficial effects of rocking on sleep relied on the activation of the vestibular system and might thus suggest some shared neurophysiological mechanisms in mammals.

MedicalResearch.com Interview with: Jeff D. Williamson, MD Geriatric Medicine - Sticht Center Wake Forest Baptist Medical Center MedicalResearch.com: What is the background for this study? Response: A growing amount of epidemiologic research has suggested that higher blood pressure is associated with higher risk for dementia, including Alzheimer’s dementia. MedicalResearch.com: What are the main findings? Response: More than 9,300 ambulatory, community dwelling persons over age 50, 30% of whom were over the age of 75, were randomly assigned to a blood pressure goal of 120 vs 140.  Persons in the 120 group had a 19% lower risk for developing MCI an transitional stage between normal and dementia (P<.008).  There was a 17% lower risk for developing dementia but this only achieved a p value = 0.10.  The combined risk for both MCI and dementia was 15% lower in the 120 group (p<0.04).  The dementia outcome was the primary outcome but all the outcomes were pre-specified in the protocol at the beginning of the trial.  Unfortunately the blood pressure intervention was stopped after only 3.3 years due to CVD and mortality benefit and this may well have influenced the ability to reach the expected number of dementia cases.  (more…)
Author Interviews, Flu - Influenza, Infections, PLoS, University of Michigan / 25.01.2019

MedicalResearch.com Interview with: Betsy Foxman PhD Hunein F. and Hilda Maassab Endowed Professor of Epidemiology Director, Center for Molecular and Clinical Epidemiology of Infectious Diseases Ann Arbor, Michigan 48109-2029 MedicalResearch.com: What is the background for this study? Response: Influenza is a major cause of human illness and death worldwide. Vaccines are the best available means of prevention. However, vaccine effectiveness has been low to moderate in recent years and coverage remains low in many countries. There is increasing evidence suggesting the microbiome plays an important role in shaping host immunity and may be a potential target for reducing disease. In our study, we used a household transmission study to explore whether the respiratory microbiome was associated with influenza susceptibility.  (more…)
Author Interviews, Cancer Research, HPV, Infections / 25.01.2019

MedicalResearch.com Interview with: Prof. J. (Hans) Berkhof PhD Vrije Universiteit Amsterdam  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: In most countries, the Pap test is used for cervical cancer screening but recently several countries have switched from Pap testing to HPV testing. Like the Pap test, the HPV test requires a cervical sample to be taken by a clinician. Vaginal self-sampling is also used, but only in underscreened women. We know that self-sampling increases screening participation in underscreened women and it is likely that many women that attend screening also prefer self-sampling if it had been offered to them. We studied whether an HPV self-sampling test is an accurate alternative to a regular HPV test in women invited for routine screening. We randomized about 14,000 women, invited for screening, to self-sampling or clinician-sampling. Women with a positive HPV test result also received the other HPV test. We found that the HPV self-sampling test yielded similar performance as the regular HPV test for detection of cervical pre-cancerous lesions (CIN3 and CIN2).  (more…)
Accidents & Violence, Author Interviews, Emergency Care, JAMA, Yale / 24.01.2019

MedicalResearch.com Interview with: Edouard Coupet Jr, MD, MS Assistant Professor Department of Emergency Medicine Yale School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: For many individuals with nonfatal firearm injuries, their only point of contact with the healthcare system may be the emergency department. Both hospital-based violence intervention programs and counseling and safe firearm storage have shown promise in reducing the burden of firearm injury. In this study, one third of individuals with firearm injuries presented to non-trauma centers. Only 1 out of 5 firearm injuries were assault injuries that led to admission to trauma centers, the population most likely to receive interventions to reduce re-injury.  (more…)
Aging, Author Interviews, Neurological Disorders / 24.01.2019

MedicalResearch.com Interview with: Rachael D. Seidler, PhD Professor, Applied Physiology & Kinesiology University of Florida MedicalResearch.com: What is the background for this study? Response: There is accumulating evidence that spaceflight impacts the human brain: the brain is shifted higher within the skull and there are some regions of gray matter increases and decreases. To date, no studies have looked at the impact of spaceflight on human brain white matter pathways. Rodents flown in space show decreased myelination of white matter pathways. Here, we analyzed brain MRI scans pre and post spaceflight to quantify fluid shifts and white matter changes. (more…)
Author Interviews, Cancer Research, Genetic Research, Weight Research / 24.01.2019

MedicalResearch.com Interview with: Brian R. Lane MD PhD Division of Urology Spectrum Health Grand Rapids, Michigan MedicalResearch.com: Can you explain how you conducted your study, and what the main findings were? Response:  We used large-scale genome-wide association studies (GWAS) to identify genetic variants associated with obesity measures, blood pressure, lipids, type 2 diabetes, insulin, and glucose. these genetic variants were used as proxies for the above-mentioned risk factors and evaluated in relation to renal cell carcinoma risk (kidney cancer) using GWAS data from 10,000 RCC patients and 20,000 control participants. -          Based on these genetic data, we found that multiple measures of obesity, as well as diastolic blood pressure (DBP) and fasting insulin, are associated with renal cell carcinoma risk. In contrast, we found little evidence for an association with RCC risk for systolic blood pressure (SBP), circulating lipids, overall diabetes, or fasting glucose.  (more…)
Author Interviews / 23.01.2019

MedicalResearch.com Interview with: Byron Caughey, Ph.D.  Senior Investigator Chief, TSE/prion Biochemistry Section Laboratory of Persistent Viral Diseases NIH/NIAID Rocky Mountain Laboratories . Hamilton, MT 59840 USA 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: Although prion diseases such as Creutzfeldt-Jakob disease (CJD) are rarer than many other neurodegenerative diseases in humans, they are rapidly fatal, untreatable and transmissible. Therefore it is important to be able to diagnose prion diseases as early as possible, not only to accurately inform patients, families and caregivers, but also to reduce risks of transmission and  improve prospects for developing therapeutics. Toward these goals, we have shown that our RT-QuIC prion seed amplification assays are highly accurate for diagnosing sporadic CJD using patients’ spinal fluid and/or nasal brushings in the clinical phase of disease. However, these particular specimens may not always be available, and it remains unclear how early they become RT-QuIC-positive in infected individuals in the months or years prior to the onset of overt clinical signs. We also showed recently that skin samples obtained post-mortem from sCJD patients are RT-QuIC positive. In the current study, we determined how early prion seeds appear in the rodents infected with prions in order to gain clues as to whether analyses of skin biopsies might provide a means of early preclinical detection of prion infections in humans.

Author Interviews, Hospital Acquired, Infections, Technology / 23.01.2019

MedicalResearch.com Interview with: Donna Armellino RN, DNP, CIC Vice President, Infection Prevention Northwell Health, Infection Prevention Lake Success, N. Y. MedicalResearch.com: What is the background for this study?  Response: The background for initiating this study was to assess frequently used equipment within the patient care environment following standard manual cleaning and disinfection compared to disinfection with PurpleSun’s shadowless 90-second cycle focused multivector ultraviolet (FMUV) delivery system. Microbes exist within the environment. Cleaning followed by disinfection, regardless of method, is intended to decrease levels of these microbes to minimize exposure and the risk of infection. To measure the effectiveness of the two methods of disinfection a five-point culturing method was used to assess microbial burden. This method was used to assess patient care equipment cleanliness after manual cleaning/disinfection and following the use of FMUV after an operative case and was used to sample equipment deemed cleaned/disinfected and ready for use outside the operative environment. Microbial burden was reported as colony forming units (CFUs). Comparison of the CFUs before cleaning/disinfection, after cleaning/disinfection, and after the use of FMUV allowed efficacy of the disinfection methods to be compared.  (more…)
Author Interviews, Cognitive Issues / 23.01.2019

MedicalResearch.com Interview with: Bryan D. James, PhD Assistant Professor Rush Alzheimer's Disease Center Chicago, IL 60612  MedicalResearch.com: What is the background for this study? Response: It has long been reported by patients, their family members, and physicians that many older adults experience long-term declines in their memory and thinking abilities after hospitalization. Studies have recently begun to confirm these reports by following older patients for years after hospitalization and repeatedly testing their cognitive abilities. A number of questions have yet to be answered, including which types of hospitalizations are most strongly related to cognitive decline. In this study, we sought to answer whether going to the hospital for elective procedures was as risky to the cognitive health of older adults as urgent or emergency (that is, non-elective) hospitalizations.

Author Interviews, Duke, JAMA, Mental Health Research, Pediatrics, Toxin Research / 23.01.2019

MedicalResearch.com Interview with: Aaron Reuben, MEM Department of Psychology and Neuroscience Duke University, Durham, North Carolina MedicalResearch.com: What is the background for this study? What are the main findings? (1)  Study members with greater lead exposure in childhood tended to endorse more psychiatric symptoms when assessed for psychiatric disorders in adulthood (between 18 and 38 years of age).
  1. These individuals tended to report more internalizing (e.g., depression, anxiety) and thought disorder (e.g., OCD, schizophrenia, mania) symptoms.
  2. Compared to other findings from this sample, the associations reported in this article are similar to those reported for lead and IQ, and are stronger than those reported for lead and criminal offending.
    1. Informants who knew Study members well reported higher levels of difficult adult personality traits among Study members with greater lead exposure in childhood.
    2. Specifically, Study members with greater blood lead levels at age 11 were rated as more neurotic, less agreeable, and less conscientious by 38 years of age.
    3. These personality traits have been previously linked to a number of poor life outcomes, including greater psychopathology, worse physical health, less job satisfaction, and troubled interpersonal relationships
  3. Psychiatric problems related to lead exposure could be detected as early as 11 years of age. In the 1980’s, parents and teachers of children with higher blood-lead levels had described them as displaying more antisocial behavior, hyperactivity, and negative emotions (e.g., sadness, anxiety).

MedicalResearch.com Interview with: Miriam Vos, MD, MSPH Associate Professor of Pediatrics and Director Pediatric Fatty Liver Program Emory and Children’s Healthcare of Atlanta MedicalResearch.com: What is the background for this study? What are the main findings? Response: Fatty liver disease has quickly become a common problem in children and adolescents, affecting an estimated 7 million children in the U.S.  This study resulted from our previous research demonstrating that fructose increases cardiometabolic risk factors in children with NAFLD in addition to other research that had demonstrated associations between NAFLD and sugar.    (more…)
Author Interviews, Infections, Vaccine Studies / 23.01.2019

MedicalResearch.com Interview with: ValnevaThomas Lingelbach President & CEO of Valneva MedicalResearch.com: What is the background for this study? Would you briefly explain the significance of Chikungunya disease? Response: Chikungunya is a mosquito-borne viral disease caused by the Chikungunya virus (CHIKV), a Togaviridae virus, transmitted by Aedes mosquitoes. The chikungunya virus causes clinical illness in 72-92% of infected humans around four to seven days after an infected mosquito bite. People infected with chikungunya may suffer from acute onset of fever, debilitating joint and muscle pain, headache, nausea and rash, potentially developing into long-term, serious health impairments such as visual, neurological, heart and gastrointestinal manifestations that in some extreme cases can lead to fatalities. Chikungunya outbreaks have been reported in Asia, Africa, the Americas and Europe. As of 2017, there have been more than one million reported cases in the Americas. The medical burden is expected to grow as the CHIKV primary mosquito vectors continue to further spread geographically. Currently there are no preventive vaccines against Chikungunya making it a major threat to public health. We set out to develop VLA1553, a live-attenuated vaccine candidate, as a potential solution to the growing unmet need chikungunya poses. Our hope is that having a preventative vaccine for chikungunya will allow people living in endemic areas to have peace of mind while enjoying the outdoors. (more…)
Author Interviews, End of Life Care, JAMA, Kidney Disease / 22.01.2019

MedicalResearch.com Interview with: Susan P. Y. Wong, MD MS Assistant Professor Division of Nephrology University of Washington VA Puget Sound Health Care System  MedicalResearch.com: What is the background for this study? Response: Patients who reach the advanced stages of kidney disease  must often face the difficult decision of whether to undergo maintenance dialysis. While maintenance dialysis is a remarkable therapy that has extended the lives of many patients, its benefits do not necessarily accrue in older patients with significant comorbidity and functional impairment. It is also a very demanding form of therapy that comes with its own burdens and complications. Based on our prior research in the national VA health system, 1 in 7 patients with very advanced kidney disease (or their decision makers) do not pursue dialysis. We wanted to understand how these decisions to forgo initiation of maintenance dialysis unfold. (more…)
