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

Response: Perinatal depression, which includes depression that develops during pregnancy or after childbirth, is one of the most common complications of pregnancy and the postpartum period, affecting as many as 1 in 7 pregnant women. The Task Force found that counseling can help those who are at increased risk of developing perinatal depression, and clinicians should provide or refer pregnant and postpartum individuals who are at increased risk to counseling. Clinicians can determine who might be at increased risk of perinatal depression by looking at someone’s history of depression, current depressive symptoms, socioeconomic risk factors, recent intimate partner violence, and other mental-health related factors.

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

Response: Music is just sound in air, but it carries considerable power. It captivates our brain’s reward system, we devote an enormous amount of time and money to it, and we’re just beginning to tap its therapeutic potential. We wanted to explore how something so abstract could have such an impact, and since music is so well suited to establishing and manipulating patterns of sound as it unfolds, we focused on how it manipulates expectations.

Previous research has shown that surprises are often the most emotional and pleasurable moments in music listening, but whether and how this engaged the brain’s reward system was unclear. So we adapted an experimental protocol designed for studying learning and surprise about more concrete rewards like food or money, and applied it to a musical context during brain imaging. This protocol relies on participants making decisions from which we could infer their expectations, allowing us to estimate how surprised they were by each outcome whenever it occurred. In our case, we asked participants to make choices about colors and directions that were associated with different musical outcomes, but we didn’t tell them what those associations were so that they they started with no expectations and learned as they went.

We found that our participants could learn about music just like they would learn about how to find food or win money, and that the same neural process was involved. Specifically, we saw that the activity of the nucleus accumbens — a central hub of the reward system — reflected both how pleasant and how surprising each musical outcome was: a computation known as a reward prediction error. Across individuals, those who better represented these reward prediction errors in their nucleus accumbens also learned better about the music in the experiment, making more decisions over time to find the music they preferred.  Continue reading

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

Response: Before 2009, etanercept (Enbrel®), infliximab (Remicade®), and adalimumab (Humira®) were the only tumor necrosis factor (TNF) inhibitors approved by the FDA for rheumatoid arthritis. Subsequently, 3 therapies gained FDA approval: subcutaneous golimumab (Simponi®) in April 2009, certolizumab pegol (Cimzia®) in May 2009, and intravenous golimumab (Simponi Aria®) in July 2013. All 6 agents are brand-name drugs.

Our study aimed to evaluate how the prices of existing TNF inhibitors (Enbrel®, Remicade® and Humira®) changed in response to the market entry of new TNF inhibitors.  Continue reading

Highest NSAID Usage Levels in Working Age Adults Linked to Greater Risk of Kidney Disease

MedicalResearch.com Interview with:
Alan Nelson, MPAS, PhD
Division of Primary Care and Population Health, Department of Medicine

Stanford, California 

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

Response: The past research literature has provided relatively little information on the appropriate level of concern regarding non-steroidal anti-inflammatory drugs (NSAIDs) and kidney disease risk among younger, apparently healthy patients. Clinicians are generally most concerned about the effects of these medications on the kidneys among patients with existing renal impairment and persons at risk for it, especially older patients.

Given that NSAID use appears to be high and rising in the US, we were interested in developing evidence on this topic in a population of working-age adults.

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

Response: Cardiovascular disease is caused by the build up of white blood cells and fat in arteries. We have known for a long time that poor sleep is associated with an increased risk of developing cardiovascular disease. A number of human observational studies have found this correlation. However, the reasons for this correlation have been largely unknown.

Our study, performed in mice, provides one possible explanation. We found that when we disturbed the sleep of mice they produced more inflammatory white blood cells. These cells caused larger lesions in their arteries and more advanced cardiovascular disease.

We found that his phenomenon is controlled by a hormone produced in the brain that normally suppresses the production of white blood cells. When mice have their sleep disturbed this pathway breakdown causing the increased production of white blood cells.

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

Response: In a randomized clinical trial entitled, “Quality of Life in Patients With Low-Risk Prostate Cancer Treated With Hypofractionated vs Conventional Radiotherapy” the NRG Oncology Group previously demonstrated that men with low risk prostate cancer had  similar 5-year disease- free survival of about 85%  when treated with either conventional radiotherapy  (C-RT) of 73.8 Gy in 41 fractions over 8.2 weeks, or with  hypofractionated radiotherapy (H-RT) of 70 Gy in 28 fractions over 5.6  weeks. However, late physician reported side effects of mild bowel and bladder symptoms were increased in patients treated  with H-RT and raised questions if the H-RT arm is acceptable to patients.

The current study asked the patient’s directly about their bowel, bladder, sexual function, anxiety, depression and general quality of life using valid patient reported questionnaires. These questionnaires have been found to be more accurate for reporting patient symptoms than physician report alone.

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

Response: In many countries, disability pensions are granted to working-aged persons who are likely to never work full-time again because of a chronic disease or injury diagnosed by a physician. In addition to serving as an important indicator of chronic disease, disability pensions are associated with high societal costs.

Hence, we examined whether cardiorespiratory fitness and obesity (two potentially modifiable factors) were associated with disability pension later in life.

Our main findings were that low physical fitness and/or obesity during adolescence, were strongly associated with disability pension later in life due to a wide range of diseases and causes.  Continue reading

Response: Lightheadedness with standing is an important risk factor for falls. Sodium is often considered a treatment for lightheadedness with standing.

We examined this in the setting of a monitored feeding study where adults ate each of 3 different sodium levels for 4 weeks at a time. Participants took 5 day breaks between sodium levels and ate the sodium levels in random order. We tested the hypothesis that lowering sodium would worsen how much lightheadedness the study participants reported.

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

Response: Secondary analyses of trials showing efficacy and safety of thrombectomy within 6-8 hours of stroke onset showed that patients who were transferred to centers performing thrombectomy from another hospital had worse outcomes than patients who presented directly to the thrombectomy centers. We wanted to assess if the thrombectomy outcomes differ between transferred patients and patients directly coming to the thrombectomy centers when patients are selected with advanced perfusion imaging.

We found that thrombectomy outcome rates were similar between patients who presented directly vs transferred from another hospital, including functional independence and safety outcomes.

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.  Continue reading

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: 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.

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.  Continue reading

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.

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.  Continue reading

Psychiatric Problems Related to Lead Exposure Detected As Early As Age 11

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).

Changing Attitudes Toward Liver Transplant for Alcohol-Associated Liver Disease

MedicalResearch.com Interview with:

Norah Terrault, MD MPH Professor, Gastroenterology Department of Medicine University of California San Francisco

Prof. Terrault

Norah Terrault, MD MPH
Professor, Gastroenterology
Department of Medicine
University of California San Francisco

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

Response: Rates of liver transplantation (LT) for alcohol-associated liver disease (ALD) are rising such that ALD recently became the most common reason for LT in the United States. Although some assume that the increase in LT for ALD is because LT for hepatitis C has declined since the advent of antiviral therapy, little research has been done to formally investigate this hypothesis, or other reasons for the increase.

This national registry study used the United Network for Organ Sharing database and included over 32,000 liver transplant recipients, including 9,438 patients with ALD. The main findings are that

1) liver transplantation for ALD has doubled in the past 15 years, but only 48% of the increase in LT for ALD can be explained by declining LT for hepatitis C;

2) Many liver transplantation centers require patients to be abstinent at least 6 months to be eligible for LT for alcohol-associated liver disease, but this is changing – our trends analysis strongly suggest that shifting attitudes of transplant providers to allow earlier LT for ALD are an important part of the increase in LT for ALD, and are variable across different geographic regions;

3) Late post- liver transplantation survival after 5-years is 11% lower for alcohol-associated liver disease (vs. non-ALD).  

MedicalResearch.com: What should readers take away from your report?

Response: Changing attitudes regarding liver transplantation for acute alcoholic hepatitis may be having broad effects on LT for alcohol-associated liver disease, as more LT providers believe that it is justified to pursue earlier LT for ALD. As attitudes continue to change with more data to suggest that early LT for ALD can be undertaken with acceptable outcomes, we may see further increases in liver transplantation for ALD in future years. Since attitudes are provider-specific, and there is no national transplant policy for LT eligibility in terms of pre-LT abstinence requirements, this study suggests that variable policies and provider attitudes may be leading to inequity in healthcare access for alcohol-associated liver disease patients in need of liver transplantation.

MedicalResearch.com: What recommendations do you have for future research as a result of this work?

Response: Given the significant increase in liver transplantation for alcohol-associated liver disease, which was different across regions, there would be value in a national policy to guide the management of LT for ALD. It is unclear why late survival for ALD is inferior for non-ALD, but other studies have shown recurrent alcohol use, malignancy, and infections to be important causes of late death after liver transplantation — these should be specifically investigated in future studies of liver transplantation for ALD.

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

Response: Tinnitus is experienced is experienced by a large proportion of the population and affects more than 15% of the population worldwide (estimated 70 million people in Europe). However, for near 3% of the population, tinnitus becomes a chronic bothersome and incapacitating symptom. Severe tinnitus interferes with sleep, mood, and concentration and thus impacts life quality, ultimately leading to sick leave and disability pension. A high cost to society has been reported, and since the prevalence of tinnitus has been predicted to double in Europe by 2050, there is an important need for an effective treatment. And today there are none, with the exception of cognitive behavioral therapy, which helps coping with it but does not remove the tinnitus. There has been a number of innovative treatment approaches, but they are overall not successful and it is now agreed that it is likely because tinnitus is a heterogeneous condition – meaning that we cannot consider tinnitus a single entity but an ensemble of different forms or subtypes, which need to be defined.

Tinnitus has always been considered a condition influenced by environmental factors, but our initial studies suggested the opposite. Adoption studies are excellent in showing the influence of shared-environment effects and establish a genetic basis for a disease or a trait. It allows to test the transmission of a trait between the adoptee and their biological or their adoptive parent. Transmission via the biological parent is expected to be due to a heritable genetic effect, while transmission via the adoptive parent is associated with home-environment, the so-called shared-environmental effect. We used medical registry data to identify tinnitus patients and adoptees.

Zika: Simple General Movement Assessment Tool Can Predict Babies at Risk of Developmental Problems

Karin Nielsen-Saines, MD, MPH

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

Response: Our study used a very simple evaluation called GMA (General Movement Assessment tool) which checks baby movements at approximately 3 to 5 months of age.

We examined 111 babies exposed to maternal illness during the Zika epidemic in Brazil and 333 control babies without this exposure by GMA at 3 months  and then tested them through standard neurodevelopmental tests at the age of 12 months.

We found that this simple evaluation, which consists of filming a baby lying down on their back for one minute and studying their movements worked extremely well in predicting which babies would or would not have future problems in their neurodevelopment. The study advances knowledge in the area because a simple one minute video of a baby can predict neurodevelopment, something that is extremely hard to determine in young babies.  This is true even in places where sophisticated brain scans are available. By identifying which babies are at risk of developmental problems early on, professionals can rapidly refer these babies to  stimulation programs when they are very young, which increases their chances of having better outcomes. Because the brains of young children respond much better  to stimulation, the timing of interventions to improve their development is very important, that is why they need to be identified early.

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

Response: n 2017, the results from the much-awaited Canakinumab Anti-inflammatory Thrombosis Outcome Study (CANTOS) trial were published, confirming the inflammatory hypothesis, i.e. that targeting inflammation can reduce cardiovascular disease. The trial tested the monoclonal antibody canakinumab in a population of post-myocardial infarction patients with elevated inflammation markers (hs-CRP). Canakinumab is currently used for rare diseases and carries an orphan drug price: the 150mg dose used in CANTOS costs approximately $73,000 per year.

Due to the high prevalence of cardiovascular disease, millions of patients could potentially be eligible for treatment with this high-priced anti-inflammatory drug. Therefore, we wanted to investigate the cost-effectiveness for canakinumab for secondary prevention of cardiovascular disease, using the reported results from CANTOS.

Medical Marijuana Users Preferred Cannabis to Pharmaceuticals

MedicalResearch.com Interview with:

Daniel J. Kruger, PhD Research Assistant Professor University of Michigan

Dr. Kruger

Daniel J. Kruger, PhD
Research Assistant Professor
University of Michigan

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

Response: We study health-related behaviors, such as diet and the consumption of caffeine and alcohol.

Given the recent trends in legalization of cannabis for medical and even recreational purposes, we were concerned with the narrow focus of current public health efforts regarding cannabis. Although some in the field take a harm-reduction approach to substance use, too many efforts focus solely on abstinence. These programs are a legacy from the era of prohibition, and we know that there are disadvantages to such a restricted scope in public health.

For example, municipalities that eliminated or blocked accurate and effective sex education had increases in teenage pregnancy rates. There are so many public health-related aspects of cannabis, beyond risks and adverse effects, which need to be addressed by systematic scientific research. Because of the legal history of cannabis, there is little integration with the mainstream health care system.

The focus of the current study was investigating how medical cannabis users perceived medical cannabis in comparison to pharmaceutical drugs and other aspects of the mainstream health care system and how they navigated they relationships between these currently separate systems

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

Response: Mitochondria are organelles that are involved in vital functions in eukaryotic cells, e.g., energy production. Even though they carry their own DNA (mitochondrial DNA, or mtDNA), most of the proteins required for mitochondrial function are encoded by the nuclear genome. Thus, mitochondrial and nuclear proteins must work together in a coordinated manner for proper mitochondrial function. These interactions can sometimes be disrupted leading to phenotypic consequences in inter-species and inter-population laboratory crosses of model organisms when the ancestry of the mitochondrial genome is very different from the nuclear genome.

While human populations are genetically not very different from each other, it has been suggested that recent admixture between geographically distant populations might also have phenotypic consequences in humans. We investigated whether there is evidence for this in six different recently admixed populations from the Americas.
