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

Response: Tree nuts are among the most common food allergies and are a major cause of fatal and near fatal reactions. Patients with tree nut allergy are often allergic to several nuts, further increasing the risk of accidental exposures, dietary limitations, and the emotional burden and anxiety in affected patients.

In the past 10 years, oral immunotherapy (OIT) has shown promise as a treatment modality for milk, egg and peanut allergies. However, limited data exists on oral immunotherapy for tree nuts and the treatment is complicated by the high prevalence of co-allergy to several nuts.

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

Response: In 2008, the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) Maternal–Fetal Medicine Units Network published the results of a randomized controlled trial of magnesium sulfate for the prevention of cerebral palsy (CP). The results of this trial suggested that fetal exposure to magnesium sulfate before anticipated early preterm delivery did not reduce the combined risk of moderate to severe cerebral palsy or death, although the rate of cerebral palsy was reduced among survivors. As such, the search for a biomarker or a therapeutic solution to prevent CP had to continue.

We are grateful to the NICHD for giving us access to the umbilical cord blood samples retrieved at the time of birth for the infants enrolled, who were also followed for 2 years postnatally. We discovered that fetus’s ability to switch-on haptoglobin (Hp) expression in response to inflammation was associated with reduction of intra-ventricular hemorrhage (IVH) and/or death, and cerebral palsy and/or death. Fetuses unable to mount such a response in-utero had an increased risk of adverse outcomes.

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

Response: The antidiabetic drug metformin is increasingly used in pregnancy: to treat gestational diabetes and type 2 diabetes, and to prevent pregnancy complications related to polycystic ovary syndrome (PCOS) and obesity. Metformin passes the placenta, and the fetus is thus exposed to the drug. Although no teratogenicity has been reported, metformin might have long-term effects on offspring health.

This study is a follow-up of cardiometabolic risk factors of 141 5- to 10-year-old children born in the PregMet study. This study was a double-blind, randomized controlled trial (RCT) designed to test the hypothesis that metformin given throughout pregnancy reduces the prevalence of pregnancy complications that are associated with the common endocrine disorder PCOS. Pregnant women with PCOS were randomized to receive metformin or placebo throughout pregnancy.  Continue reading

Paris, France

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

Response: Most studies on direct acting antivirals were focused on sustained vriological response (SVR) rates, but few studies addressed the issue of clinical outcomes.


MedicalResearch.com: What are the main findings?

Response: Treatment of hepatitis C with direct acting antivirals (DAA) is associated with reduced risk of mortality and liver cancer. 

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

Response: This suggests that direct acting antivirals should be considered for all patients with chronic hepatitis C infection.

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

Response: Follow-up of cohort participants will continue to assess the long term impact of DAA on clinical outcomes, namely: decompensated cirrhosis (in patients with cirrhosis); residual risk of hepatocellular carcinoma, regression of  liver fibrosis and morbidity not related to the liver (particulary cardiovascular events). 

Disclosures: The study was sponsored by ANRS_INSERM

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.

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: 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.  Continue reading

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

Response: We are both practicing stroke physicians as well as clinical trialists. Therefore our interest in this area was triggered by the exciting results of the FLAME trial in 2011. This appeared to indicate that fluoxetine might boost the recovery of stroke patients. Potentially this was very important given the increasing numbers of people having disability due to stroke, and the fact that fluoxetine is inexpensive and could be introduced very easily into clinical practice. We were further encouraged by the large numbers of small RCTs we identified when we carried out a Cochrane systematic review on the topic. These trials provided more evidence of potential benefit but there was evidence that trials of greater quality showed less benefit, and benefits were greater in patients who were depressed. We felt there was a need for more evidence derived from much larger numbers of patients.

Successful Trial of Cefiderocol For Resistant & Complicated Urinary Tract Infections

MedicalResearch.com Interview with:
https://www.shionogi.com/Simon Portsmouth, MD

Senior Medical Director
Shionogi Inc.

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

Response: Antibiotics for multidrug resistant  Gram-negative infections are desperately needed. Cefiderocol is the first siderophore antibiotic to reach patients.

Siderophore antibiotics bind to free iron and use the bacterial active iron transport channels to cross the outer membrane of Gram-negative bacteria. Laboratory studies have shown that cefiderocol is active against multi-drug resistant Gram-negative bacteria, often where no other antibiotics are active. It is able to overcome most types of antibiotic resistance due to its active transport into cells and stability against all carbapenemases.

The need for antibiotics for carbapenem resistant Gram-negative infections is described as a critical need by the WHO. This trial was the first in humans with serious infections and demonstrated excellent efficacy in a complicated patient population where almost ¼ were over 75 years of age. Additionally cefiderocol did not appear to have any safety problems, and was well tolerated.

AI: Deep Learning Algorithms Can Detect Critical Head CT Findings

MedicalResearch.com Interview with:
Qure-ai.jpgSasank Chilamkurthy

AI Scientist,

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

Response: Head CT scan is one of the most commonly used imaging protocols besides chest x-ray. They are used for patients with symptoms suggesting stroke, rise in intracranial pressure or head trauma. These manifest in findings like intracranial haemorrhage, midline shift or fracture.

Scans with these critical findings need to be read immediately. But radiologists evaluate the scans on first-come-first-serve basis or based on stat/routine markers set by clinicians. If the scans with critical findings are somehow pushed to the top of radiologists’ work list, it could substantially decrease time to diagnosis and therefore decrease mortality and morbidity associated with stroke/head trauma.

Could a Low-Gluten Diet During Pregnancy Protect Offspring from Diabetes?

MedicalResearch.com Interview with:
Knud Josefsen, senior researcher
Bartholin Institute, Rigshospitalet,
Copenhagen K, Denmark

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

Response: In a large population of pregnant women, we found that the risk of the offspring being diagnosed with type 1 diabetes before the age of 15.6 years (the follow up period) was doubled in the group of women ingesting the highest amounts of gluten (20-66 g/day) versus the group of women ingesting the lowest amounts of gluten (0-7 g/day). For every additional 10 grams of gluten ingested, the risk for type 1 diabetes in the child increased by a factor of 1.31.

It the sense that it was a hypothesis that we specifically tested, we were not surprised. We had seen in animal experiments that a gluten-free diet during pregnancy protected the offspring from diabetes, and we wanted to see if we could prove the same pattern in humans. There could be many reasons why we would not be able to show the association, even if it was there (sample size, low quality data, covariates we could not correct for and so on), but we were off course pleasantly surprised that we found the association that we were looking for, in particular because it is quite robust Continue reading
