Response:  For most undocumented immigrants with kidney failure in the U.S., access to hemodialysis is limited and they can only receive it when they are critically ill and near-death.  This type of “emergency-only” hemodialysis is already known to be nearly 4-fold more costly, has 14-fold higher mortality rate, and leads to debilitating physical and psychosocial distress for these patients compared to those receiving regular hemodialysis.

This study shows that clinicians who are forced to provide this substandard care are also harmed.  They experience moral distress, emotional exhaustion, and several other drives of professional burnout due to witnessing needless suffering and high mortality.  Continue reading

Response: Risk stratification of patients with a non-ST-segment elevation acute coronary syndrome (NSTE-ACS) remains a major challenge in clinical cardiology. Risk stratification is important to identify patients at high risk, to whom an early coronary intervention with optimal adjunctive medical therapy shall be applied to reduce that risk. Conversely, it is equally important to identify patients at low risk, to whom a potentially hazardous invasive therapy or a multi-drug administration shall be avoided. Current ACC/AHA and ESC guidelines agree in a standardized approach that uses Global Registry of Acute Coronary Events (GRACE) score, a well validated scoring system, to calculate a patient’s risk and guide triage and management decisions.

Amyloid-β (Aβ) 1-40 and 1-42 peptides (Aβ40 and Aβ42), are proteolytic fragments of a larger protein, the amyloid precursor protein (APP) cleaved by β- and γ-secretases, found in typical brain amyloid deposits in Alzheimer’s disease. Many lines of evidence support a role of Aβ40 in cardiovascular disease as a peptide with pro-inflammatory and pro-thrombotic properties. Most cardiovascular risk factors seem to affect APP metabolism and thus, Aβ production and its soluble circulating APP770 isoform are elevated in patients with ACS_ENREF_15, suggesting a role for Aβ40 in the triggering and outcome of ACS in stable CAD patients. Although vascular inflammation is considered as a hallmark in the pathophysiologic pathways of coronary artery disease (CAD) and novel mechanisms are continuously recognized in its pathogenesis, no inflammatory marker is currently recommended for risk stratification of patients with NSTE-ACS individually or as a component of the GRACE score. This may partly explain the moderate discriminative ability of GRACE score in some studies, especially in older patients and those after early percutaneous coronary intervention (PCI).

In this retrospective study, we used data from two independent prospective cohorts, the Heidelberg study (n=1,145) and the validation multicenter international APACE (Advantageous Predictors of Acute Coronary Syndrome Evaluation, n=734) study and determined the clinical prognostic and reclassification value of baseline circulating Aβ40 levels in the prediction of mortality over the GRACE risk score in patients with NSTE-ACS across a median follow-up of 21.9 ( Heidelberg cohort) and 24.9 months (APACE cohort), respectively.

MedicalResearch.com: What is the background for this study

Response: Most Americans know that the United States faces an epidemic of deaths due to drug overdose.  And many are also aware that there is a critical shortage of organs available for transplant.  Perhaps less widely known is that today, more than 1 in every 8 deceased organ donors died from a drug overdose.  The objective of our study was to look at the outcomes of patients who received transplants with organs donated after an overdose.

Brain Center Rudolf Magnus, University Medical Center Utrecht, Utrecht, the Netherlands


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

Response: During the past two decades, the frequency of hearing loss among young people has increased and going to music concerts, clubs and festivals may part of the reason. Noise-induced hearing loss because of recreational noise exposure is reduced by using earplugs.

Our study evaluated 51 adults who attended an outdoor music festival in Amsterdam, the Netherlands, in September 2015. The study measured music festival visit for 4.5 hours (intervention); temporary hearing loss (outcome).

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

Response: Since major gun law reforms in 1996, Australian has seen zero mass shootings (five or more deaths, not including the perpetrator).The law reforms outlawed semi-automatic rifles, those often favored by mass killers.

In the 18 years prior to the reforms, Australia experienced 13 mass shootings. The National Rifle Association and others have suggested that the 22 year absence of mass shootings may simply reflect that these events are rare and statistically unlikely to occur regardless of any policy.

Hand Osteoarthritis: Hydroxychloroquine No More Effective Than Placebo

MedicalResearch.com Interview with:
Dr Sarah Kingsbury PhD
Osteoarthritis Strategic Lead
Deputy Section Head, Musculoskeletal Medicine and Imaging

University of Leeds

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

Response: Osteoarthritis of the hand is a painful and disabling condition, estimated to effect up to 31 per cent of people aged over 70. It can stop people from carrying out everyday activities and can limit their quality of life. The first-line pharmacological treatments for hand osteoarthritis, including paracetamol and non-steroidal anti-inflammatory drugs, are often not effective and are associated with side effects. Doctors have used hydroxychloroquine, an established treatment for rheumatoid arthritis, as an off-label alternative, supported by increasing evidence that inflammation is a factor in osteoarthritis. Until now, there has not been a large-scale study into whether using hydroxychloroquine works.

HERO was a 12 month randomised, double-blind, placebo controlled, pragmatic trial, designed with a view to replicate anecdotal reports of hydroxychloroquine use in clinical practice, and  powered to detect a moderate effect equivalent to that for NSAIDs in this population. The study involved 248 patients at 13 NHS hospitals in England: all had the condition for at least 5 years, had changes to the joints in their hands consistent with osteoarthritis and reported moderate to severe pain on at least half of the days in the previous three months to the study commencing.

Participants were randomised 1:1 to either hydroxychloroquine or placebo and followed up at 3 monthly intervals for 12 months. The study found that patients initially reported a small reduction in the severity of pain before the improvement plateaued. However, a similar amount of change was seen in both the group receiving hydroxychloroquine medication and the group taking the placebo.

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

Response: Esophageal cancer (EC) remains a global concern because of its increasing incidence and persistently poor survival. It poses a bigger threat to less developed regions and men.

Tea is one of the most common beverages worldwide and usually consumed at elevated temperature. Existing evidence remains inconclusive as to the association between tea consumption and EC risk. Tea consumers, especially in Chinese men, are more likely to smoke and drink alcohol. Tobacco smoking and alcohol consumption, as well as the chemical compounds and adverse thermal effect of high-temperature tea, considerably complicate the association between tea consumption and esophageal cancer risk.

University of Cambridge 

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

Response: This systematic review supports and expands previous research suggesting that living kidney donors have no increased risk for several major chronic diseases, with the exception of end stage renal disease. Female donors seem to be at increased risk for preeclampsia. Furthermore, there was no evidence that living kidney donors had higher risk for mortality, cardiovascular disease, or type 2 diabetes, or reduced quality of life. –

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

Response: This study highlights the low but real risks of living kidney donation and emphasise the importance of careful assessment and counseling for all living kidney donors. 

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

Response: While this systematic review and meta-analysis provide some important answers, the field is still a long way from offering precise risk estimates to prospective donors.

Marijuana plant (Cannabis sativa)

MedicalResearch.com Interview with:
Divya Ravi, MD, MPH

The Wright Center for Graduate Medical Education
Scranton, PA

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

Response: There is evidence to suggest that Marijuana can bring about changes at the tissue level and has the ability to potentiate vascular disease, in ways similar to tobacco.  With change in legalization and increase usage trends, we conducted this review to examine the known effects of marijuana on cardiovascular outcomes and risk factors, given that cardiovascular disease remains the greatest cause of morbidity and mortality worldwide.

Our review found insufficient evidence to draw meaningful conclusions that marijuana use is associated with cardiovascular risk factors and outcomes. The few studies that suggested a possible benefit from marijuana use, were cross-sectional, and were contradicted by more robust longitudinal studies that reported potential harmful effects.
