Will COVID become a disease of the young?

Reporter: Danielle Smolyar, Research Assistant 3 – Text Analysis for 2.0 LPBI Group’s TNS #1 – 2020/2021 Academic Internship in Medical Text Analysis (MTA)

An increase of infections among youth who are unvaccinated in countries with high vaccination rates is getting noticed in the role of young people in the pandemic.

On June 21 is Ross Ministry of health recommended that all individuals between the ages of 12 and 15 should be vaccinated. This makes the nation one of the few that have been approved vaccinations for younger kids. This decision came about in response too many other countries with high rates of vaccination are experiencing an increase in numbers of infections that are found to be in younger age groups.

Israel’s vaccination campaign which has reached to more than 85% of the adult population to be vaccinated noticed that case numbers are dropping around a dozen daily in the month of June. At the end of June, they have realized that the cases began to rise to more than 100 cases a day. These cases were found in kids under the age of 16 which is why the government decided to allow vaccinations.

Ran Balicer, and epidemiologists at Israel’s largest healthcare provider in Tel Aviv said that the younger profile is not surprising.

This trend that Israel started to notice is not just happening in Israel. The United States and the United Kingdom COVID-19, “become a disease of the unvaccinated, who are predominantly young”, says Joshua Goldstein, a demographer at the University of California, Berkeley. Stated in the article. 

This trend has been occurring in the countries where the older population were being vaccinated first. Follow the drop in age because they were vaccinating older people who are the most at risk for the disease.

This shift has shut attention to the studies of transmission in the younger age groups. Karin Magnusson immunologist said that it has come very important to understand the burden of the disease among the younger children. 

Magnusson on the impact of COVID-19 in children in Norway. On June 5 pre-print she reported that children see their doctor regularly up to six months after contracting Covid-19.

Balicer, is studying the virus spread in multi-generational households in Israel. Going beyond whether vaccinating children or not the patterns of COVID-19 infection have caused discussions about mask wearing to adolescence and kids in Israel. 

As stated in the article, “As the burden of cases shifts towards younger people, arguments for vaccinating adolescents will become slightly more compelling,” agrees Nick Bundle, an epidemiologist at the European Centre for Disease Prevention and Control in Stockholm.” However, the risk of disease in children still is low and in other countries the total number of cases have declined.

Countries also need to consider the global contacts. As stated in the article, “Are we really better off giving the vaccine to kids in rich countries than to older people [in less wealthy countries] where it might have a much bigger impact on people’s lives?” says Jennie Lavine, who studies infectious-disease dynamics at Emory University in Atlanta, Georgia. “It seems hard for me to imagine a really good argument for that.”

Oh there is a downward shift and the average age of infected with COVID-19 in countries with high COVID-19 vaccination rates it may be short-lived. There could be a few scenarios where the shift could bounce back says Henrik Salje, who is an infectious disease epidemiologist at the University of Cambridge, UK. Many of the countries could start vaccinating the adolescence just like Israel and the United States are already doing so. 

Bundle says that COVID- 19 can still be present in younger kids. “But how big a problem that is, is not a simple thing to respond to.”

COVID and the brain: researchers zero in on how damage occurs

Reporter: Danielle Smolyar

Research Assistant 3 – Text Analysis for 2.0 LPBI Group’s TNS #1 – 2020/2021 Academic Internship in Medical Text Analysis (MTA)

Recent evidence has indicated that coronavirus can cause brain fog and also lead to different neurological symptoms. 

Since the beginning of the pandemic, researchers have been trying to understand how the coronavirus SARS-CoV-2 affects the brain

New evidence has shown how coronavirus has caused much damage to the brain. There is a new evidence that shows that COVID-19 assault on the brain I has the power to be multipronged. What this means is that it can attack on certain Brain cells such as reduce the amount of blood flow that the brain needs to the brain tissue.

Along with brain damage COVID-19 has also caused strokes and memory loss. A neurologist at yell University Serena Spudich says, “Can we intervene early to address these abnormalities so that people don’t have long-term problems?”

We’re on 80% of the people who have been hospitalized due to COVID-19 have showed brain symptoms which seem to be correlated to coronavirus.

At the start of the pandemic a group of researchers speculated that coronavirus they can damage the brain by infecting the neurons in the cells which are important in the process of transmitting information. After further studies they found out that coronavirus has a harder time getting past the brains defense system and the brain barrier and that it does not affect the neurons in anyway.

An expert in this study indicated that a way in which SARS-CoV-2 may be able to get to the brain is by going through the olfactory mucosa which is the lining of the nasal cavity. It is found that this virus can be found in the nasal cavity which is why we swab the nose one getting tested for COVID-19.

Spudich quotes, “there’s not a tonne of virus in the brain”.

Recent studies indicate that SARS-CoV-2 have ability to infect astrocytes which is a type of cell found in the brain. Astrocytes do quite a lot that supports normal brain function,” including providing nutrients to neurons to keep them working, says Arnold Kriegstein, a neurologist at the University of California, San Francisco.

Astrocytes are star-shaped cells in the central nervous system that perform many functions, including providing nutrients to neurons.

Kriegstein and his fellow colleagues have found that SARS-CoV-2 I mostly infects the astrocytes over any of the other brain cells present. In this research they expose brain organoids which is a miniature brain that are grown from stem cells into the virus.

As quoted in the article” a group including Daniel Martins-de-Souza, head of proteomics at the University of Campinas in Brazil, reported6 in a February preprint that it had analysed brain samples from 26 people who died with COVID-19. In the five whose brain cells showed evidence of SARS-CoV-2 infection, 66% of the affected cells were astrocytes.”

The infected astrocytes could indicate the reasoning behind some of the neurological symptoms that come with COVID-19. Specifically, depression, brain fog and fatigue. Kreigstein quotes, “Those kinds of symptoms may not be reflective of neuronal damage but could be reflective of dysfunctions of some sort. That could be consistent with astrocyte vulnerability.”

A study that was published on June 21 they compared eight different brands of deceased people who did have COVID-19 along with 14 brains as the control. The results of this research were that they found that there was no trace of coronavirus Brain infected but they found that the gene expression was affected in some of the astrocytes.

As a result of doing all this research and the findings the researchers want to know more about this topic and how many brain cells need to be infected for there to be neurological symptoms says Ricardo Costa.

Further evidence has also been done on how SARS-CoV-2 can affect the brain by reducing its blood flow which impairs the neurons’ function which ends up killing them.

Pericytes can be found on the small blood vessels which are called capillaries and are found all throughout the body and in the brain. In a February pre-print there was a report about how SARS-CoV-2 can infect the pericyte in the brain organoids. 

David Atwell, a neuroscientist at the University College London, along with his other colleagues had published a pre-print which has evidence to show that SARS-CoV-2 odes In fact pericytes behavior. I researchers saw that in the different part of the hamsters brain SARS-CoV-2 blocks the function of receptors on the pericytes which ultimately causes the capillaries found inside the tissues to constrict.

As stated in the article, It’s a “really cool” study, says Spudich. “It could be something that is determining some of the permanent injury we see — some of these small- vessel strokes.”

Attwell brought to the attention that the drugs that are used to treat high blood pressure may in fact be used in some cases of COVID-19. Currently there are two clinical trials that are being done to further investigate this idea.

There is further evidence showing that the neurological symptoms and damage could in fact be happening because of the bodies on immune system reacting or misfiring after having COVID-19.

Over the past 15 years it has become evident that people’s immune system’s make auto antibodies which attack their own tissues says Harald Prüss in the article who has a Neuroimmunologist at the German Center for neurogenerative Diseases in Berlin. This may cause neuromyelitis optica which is when you can experience loss of vision or weakness in limbs. Harald Prüss summarized that the autoantibodies can pass through the blood brain barrier and ultimately impact neurological disorders such as psychosis.

Prüss and his colleagues published a study last year that focused on them isolating antibodies against SARS-CoV-2 from people. They found that one was able to protect hamsters from lung damage and other infections. The purpose of this was to come up with and create new treatments. During this research they found that some of the antibodies from people. They found that one was able to protect hamsters from lung damage and other infections. The purpose of this was to come up with and create new treatments. During this research they found that some of the antibodies can bind to the brain tissue which can ultimately damage it. Prüss states, “We’re currently trying to prove that clinically and experimentally,” says Prüss.

Was published online in December including Prüss sorry the blood and cerebrospinal fluid of 11 people who were extremely sick with COVID-19. These 11 people had neurological symptoms as well. All these people were able to produce auto antibodies which combined to neurons. There is evidence that when the patients were given intravenous immunoglobin which is a type of antibody it was successful.

Astrocytes, pericytes and autoantibodies we’re not the only  pathways. However it is likely that people with COVID-19 experience article symptoms for many reasons. As stated, In the article, Prüss says a key question is what proportion of cases is caused by each of the pathways. “That will determine treatment,” he says.

Cardiac Surgery Recommendations Switch to Patient Blood Management

— Four societies outline pre- to post-op strategies to improve outcomes

by Crystal Phend, Contributing Editor, MedPage Today June 30, 2021

Reporter: Aviva Lev-Ari, PhD, RN

STS/SCA/AmSECT/SABM Update to the Clinical Practice Guidelines on Patient Blood Management

Published:June 30, 2021 DOI:https://doi.org/10.1016/j.athoracsur.2021.03.033

Switching from “blood conservation” to the broader “patient blood management” (PBM) approach is probably the biggest change, Tibi told MedPage Today.

“Basically we’re considering blood as another vital organ,” he said. “Why that is important is because now we look at a patient’s blood system as an organ that needs to be assessed and treated for the sake of that organ and not simply to decide when or when not to transfuse.”

Recommendations span the entire spectrum from preoperative assessment of bleeding risk and anemia to intraoperative perfusion and blood salvage practices to postoperative treatment with human albumin for volume replacement.

“Most hospitals around the U.S. are acutely aware of patient blood management and, to some degree or another, are implementing many of the things we are talking about,” noted Tibi, who is immediate past president of SABM. Nationwide, the amount of blood transfused in cardiac surgery has dropped 45% in the past 10 to 15 years but still ranges widely from center to center.

Reporting on a Study published on July 6, 2021 by  Oregon Health & Science University

Recently, researchers have found many ways to manipulate and alter gene activity in specific cells. As a result of seeing this alteration, it has caused much development and progress in understanding cancer, brain function, and immunity.

Tissues and Organs are composed of cells that look the same but have different roles. For example, single-cell analysis allows us to research and test the cells within an organ or cancerous tumor. However, the single-cell study has its boundaries and limits in trying a more significant number of cells. This result is not an accurate data and analysis of the cells.

Andrew Adey, Ph.D., the senior author of a paper in Nature Biotechnology, https://www.nature.com/articles/s41587-021-00962-z

Mulqueen, R. M., Pokholok, D., O’Connell, B. L., Thornton, C. A., Zhang, F., O’Roak, B. J., Link, J., Yardımcı, G. G., Sears, R. C., Steemers, F. J., & Adey, A. C. (2021, July 5). High-content single-cell combinatorial indexing. Nature News. https://www.nature.com/articles/s41587-021-00962-z

states that the new method gives us the ability to have a ten-fold improvement in the amount of DNA produced from a single DNA sequence. A DNA sequence is composed of units which are called bases. The sequence puts the bases in chronological order for it to code correctly. 

To understand cancer better, single-cell studies are a crucial factor in doing so. Different cells catch on to other mutations in the DNA sequence in a cancerous tumor, which ultimately alters the DNA sequence. This results in tumor cells with new alterations, which could eventually spread to the rest of the body. 

Adey and his team provided evidence that the method they had created can show DNA alterations that have come from cells present in tumor samples from patients with pancreatic cancer. Adey stated,

quote “For example, you can potentially identify rare cell subtypes within a tumor that are resistant to therapy.” 

Abey and his team have been working with OHSU Knight Cancer Institute, and with them, they are testing a single-cell method to see if patients’ tumors have changed by doing chemo or drug therapy. 

This new method allows itself to create DNA libraries and fragments of DNA that helps analyze the different genes and mutations within the sequence. This method uses something called an enzymatic reaction that attaches primers to the end of each DNA fragment.  For the cells to be analyzed, each primer must be present on both ends of the fragment. 

As a result of this new method, all library fragments present must-have primers on both ends of the fragments. At the same time, it improves efficiency by reducing its sequencing  price overall, that these adapters can be used instead of the regular custom workflows.

Here we are at the “end” of the road. End here between quotation, because just like any other technology-related field, there’s no end. The field is developing rapidly because new algorithms and techniques are under research as I type this article.

So, being a data scientist means you will be in a continuous learning stage. You will be developing your knowledge and your style as you go. You will probably feel more attracted to a specific sub-field than another and dig even deeper and maybe specialize in that sub-field.

The most important thing to know as you embark on this journey is, you can do it. You need to be open-minded and dedicate enough time and effort to achieve your end goals.

Ramatroban, a Thromboxane A2/TPr and PGD2/DPr2 receptor antagonist for Acute and Long haul COVID-19

Author: Ajay Gupta, MD

Subject: Ramatroban, a Thromboxane A2/TPr and PGD2/DPr2 receptor antagonist for Acute and Long haul COVID-19

While corticosteroids may have a role in about 5% of hospitalized patients who have the cytokine storm, currently there is no effective treatment for mild or moderate COVID and long haul COVID. Massive increase in respiratory and plasma thromboxane A2 (TxA2) plays a key role in thromboinflammation and microvascular thrombosis, while an increase in respiratory and plasma PGD2 potentially suppresses innate interferon response, and acquired Th1 anti-viral response, while promoting a maladaptive type 2, anti-helminthic like immune response. Ramatroban is a potent dual receptor antagonist of Thromboxane A2/TPr and PGD2/DPr2 that has been used in Japan for the treatment of allergic rhinitis for past 20 years (Baynas®, Bayer Japan). We first disclosed use of ramatroban for COVID in a provisional patent application filed on 31st March, 2020; followed by the publication Gupta et al, J Mol Genet Med, 2020

Several experts, as outlined below in yellow highlighted text, have supported the idea of using ramatroban as an anti-thrombotic and immunomodulator in COVID-19.

1.     Prof. Louis Flamand, Nicolas Flamand, Eric Boilard Laval Univ. Quebec, Canada: There is a lipid-mediator storm in COVID-19 characterized by massive increases in thromboxane A2 and PGD2 in the lungs and plasma.  “Blocking the deleterious effects of             PGD2 and TxA2 with the dual DPr2/TPr antagonist Ramatroban might be beneficial in COVID-19 Archambault et al, FASEB, June 2021, doi: https://doi.org/10.1096/fj.202100540R

2. Prof. Garret A FitzGerald, Univ. Of Pennsylvania, Member National Academy of Sciences.https://en.wikipedia.org/wiki/Garret_A._FitzGerald “In the current pandemic there may be utility in targeting eicosanoids with existing drugs.  These approaches would likely be most effective early in the disease before the development of ARDS, where cytokines and chemokines dominate. Dexamethasone limits COX-2 expression and might diminish COVID-19 severity and mortality at least in part, by diminishing COX metabolites… Dexamethasone might improve severe COVID-19 by diminishing the prostaglandins / thromboxane storm in the lungs”. “Treatment with a PGD2/DPr2 inhibitor decreased viral load and improved morbidity by upregulating IFN-lambda expression. …..  Antagonism of the thromboxane receptor (TPr) prevents ARDS…. Early administration of well-tolerated TPr antagonists may limit progress to severe COVID-19 (Theken and FitzGerald, Science, 2021)

4.     Prof. Simon Phipps, Univ. of Queensland, Brisbane Australia “It has been hypothesized that DP2 antagonists be repurposed as a novel immunotherapy for the treatment of COVID-19, and this may be appropriate in mild to moderate cases where Th1 immunity is impaired.” (Ullah et al, Mucosal Immunology, 2021)

5.     Prof. Bruce D. Hammock, Distinguished Professor, Univ of California DavisMember US National Academy of Sciences and National Academy of Inventors; April 25, 2021. https://www.entsoc.org/fellows/hammock “I find your idea of blocking specific thromboxane receptors in preventing or reducing some of the devastating co-morbidity of COVID-19 very compelling. … A DPr2 receptor blocker is conceptually attractive in offering the potential of effective therapy and low risk due to a high therapeutic index.” E mail dated April 25, 2021.  (https://ajp.amjpathol.org/action/showPdf?pii=S0002-9440%2820%2930332-1    and http://ucanr.edu/sites/hammocklab/files/328012.pdf)

6. Ann E Eakin, PhD, Senior Scientific Officer, NIH-NIAID “very compelling data supporting potential benefits of ramatroban in both reducing viral load as well as modulating host responses” E Mail dated Nov 20, 2020

7. Prof. James Ritter, MA, DPhil, FRCP, FMedSci, Hon FBPhS https://www.trinhall.cam.ac.uk/contact-us/contact-directory/fellows-and-academics-directory/james-ritter/ “Very impressive, and fascinating” referring to ramatroban for COVID-19 in an e-mail dated Dec 21, 2020

Ramatroban is expected to reduce lung fibrosis in COVID-19 and therefore diminish clinical manifestations of Long haul COVID. Pang et al, 2021 “examined the effect of Ramatroban, a clinical antagonist of both PGD2 and TXA2 receptors, on treating silicosis using a mouse model. The results showed that Ramatroban significantly alleviated silica-induced pulmonary inflammation, fibrosis, and cardiopulmonary dysfunction compared with the control group.” https://www.thno.org/v11p2381.htm

Unfortunately, the animal models of COVID-19 are harsh, lack microvascular thrombosis and immune perturbations characteristic of human disease. These models may be good for testing antivirals but not for testing immunomodulators or anti-thrombotics. There is highly positive anecdotal experience with use of ramatroban in moderately severe COVID-19 (https://www.researchsquare.com/article/rs-474882/v1

Additionally, Ramatroban holds great promise in sickle cell disease, cardiovascular disease https://doi.org/10.1111/j.1527-3466.2004.tb00132.x, and community acquired pneumonia.

This AI Just Evolved From Companion Robot To Home-Based Physician Helper

Reporter: Ethan Coomber, Research Assistant III, Data Science and Podcast Library Development 

Article Author: Gil Press Senior Contributor Enterprise & Cloud @Forbes 

Twitter: @GilPress I write about technology, entrepreneurs and innovation.

Intuition Robotics announced today that it is expanding its mission of improving the lives of older adults to include enhancing their interactions with their physicians. The Israeli startup has developed the AI-based, award-winning proactive social robot ElliQ which has spent over 30,000 days in older adults’ homes over the past two years. Now ElliQ will help increase patient engagement while offering primary care providers continuous actionable data and insights for early detection and intervention.

The very big challenge Intuition Robotics set up to solve was to “understand how to create a relationship between a human and a machine,” says co-founder and CEO Dor Skuler. Unlike a number of unsuccessful high-profile social robots (e.g., Pepper) that tried to perform multiple functions in multiple settings, ElliQ has focused exclusively on older adults living alone. Understanding empathy and how to grow a trusting relationship were the key objectives of Intuition Robotics’ research project, as well as how to continuously learn the specific (and changing) behavioral characteristics, habits, and preferences of the older adults participating in the experiment.

The results are impressive: 90% of users engage with ElliQ every day, without deterioration in engagement over time. When ElliQ proactively initiates deep conversational interactions with its users, there’s 70% response rate. Most important, the participants share something personal with ElliQ almost every day. “She has picked up my attitude… she’s figured me out,” says Deanna Dezern, an ElliQ user who describes her robot companion as “my sister from another mother.”

Higher patient engagement leads to lower costs of delivering care and the quality of the physician-patient relationship is positively associated with improved functional health, studies have found. Typically, however, primary care physicians see their patients anywhere from once a month to once a year, even though about 85% of seniors in the U.S. have at least one chronic health condition. ElliQ, with the consent of its users, can provide data on the status of patients in between office visits and facilitate timely and consistent communications between physicians and their patients.

Supporting the notion of a home-based physician assistant robot is the transformation of healthcare delivery in the U.S. More and more primary care physicians are moving from a fee-for-service business model, where doctors are paid according to the procedures used to treat a patient, to “capitation,” where doctors are paid a set amount for each patient they see. This shift in how doctors are compensated is gaining momentum as a key solution for reducing the skyrocketing costs of healthcare: “…inadequate, unnecessary, uncoordinated, and inefficient care and suboptimal business processes eat up at least 35%—and maybe over 50%—of the more than $3 trillion that the country spends annually on health care. That suggests more than $1 trillion is being squandered,” states “The Case for Capitation,” a Harvard Business Review article.

Under this new business model, physicians have a strong incentive to reduce or eliminate visits to the ER and hospitalization, so ElliQ’s assistance in early intervention and support of proactive and preventative healthcare is highly valuable. ElliQ’s “new capabilities provide physicians with visibility into the patient’s condition at home while allowing seamless communication… can assist me and my team in early detection and mitigation of health issues, and it increases patients’ involvement in their care through more frequent engagement and communication,” says in a statement Dr. Peter Barker of Family Doctors, a Mass General Brigham-affiliated practice in Swampscott, MA, that is working with Intuition Robotics.

With the new stage in its evolution, ElliQ becomes “a conversational agent for self-reported data on how people are doing based on what the doctor is telling us to look for and, at the same time, a super-simple communication channel between the physician and the patient,” says Skuler. As only 20% of the individual’s health has to do with the administration of healthcare, Skuler says the balance is already taken care of by ElliQ—encouraging exercise, watching nutrition, keeping mentally active, connecting to the outside world, and promoting a sense of purpose.

A recent article in The Communication of the ACM pointed out that “usability concerns have for too long overshadowed questions about the usefulness and acceptability of digital technologies for older adults.” Specifically, the authors challenge the long-held assumption that accessibility and aging research “fall under the same umbrella despite the fact that aging is neither an illness nor a disability.”

For Skuler, a “pyramid of value” is represented in Intuition Robotics offering. At the foundation is the physical product, easy to use and operate and doing what it is expected to do. Then there is the layer of “building relationships based on trust and empathy,” with a lot of humor and social interaction and activities for the users. On top are specific areas of value to older adults, and the first one is healthcare. There will be more in the future, anything that could help older adults live better lives, such as direct connections to the local community. ”Healthcare is an interesting experiment and I’m very much looking forward to see what else the future holds for ElliQ,” says Skuler.

Yet another Success Story: Machine Learning to predict immunotherapy response

Curator and Reporter: Dr. Premalata Pati, Ph.D., Postdoc

Immune-checkpoint blockers (ICBs) immunotherapy appears promising for various cancer types, offering a durable therapeutic advantage. Only a number of cases with cancer respond to this therapy. Biomarkers are required to adequately predict the responses of patients. This article evaluates this issue utilizing a system method to characterize the immune response of the anti-tumor based on the entire tumor environment. Researchers build mechanical biomarkers and cancer-specific response models using interpretable machine learning that predict the response of patients to ICB.

The lymphatic and immunological systems help the body defend itself by combating. The immune system functions as the body’s own personal police force, hunting down and eliminating pathogenic baddies.

According to Federica Eduati, Department of Biomedical Engineering at TU/e, “The immune system of the body is quite adept at detecting abnormally behaving cells. Cells that potentially grow into tumors or cancer in the future are included in this category. Once identified, the immune system attacks and destroys the cells.”

Immunotherapy and machine learning are combining to assist the immune system solve one of its most vexing problems: detecting hidden tumorous cells in the human body.

It is the fundamental responsibility of our immune system to identify and remove alien invaders like bacteria or viruses, but also to identify risks within the body, such as cancer. However, cancer cells have sophisticated ways of escaping death by shutting off immune cells. Immunotherapy can reverse the process, but not for all patients and types of cancer. To unravel the mystery, Eindhoven University of Technology researchers used machine learning. They developed a model to predict whether immunotherapy will be effective for a patient using a simple trick. Even better, the model outperforms conventional clinical approaches.

The outcomes of this research are published on 30th June, 2021 in the journal Patterns in an article entitled “Interpretable systems biomarkers predict response to immune-checkpoint inhibitors”.

The Study

  • Characterization of the tumor microenvironment from RNAseq and prior knowledge
  • Multi-task machine-learning models for predicting antitumor immune responses
  • Identification of cancer-type-specific, interpretable biomarkers of immune responses
  • EaSIeR is a tool to predict biomarker-based immunotherapy response from RNA-seq

“Tumor also contains multiple types of immune and fibroblast cells which can play a role in favor of or anti-tumor, and communicates among themselves,” said Oscar Lapuente-Santana, a researcher doctoral student in the computational biology group. “We had to learn how complicated regulatory mechanisms in the micro-environment of the tumor affect the ICB response. We have used RNA sequencing datasets to depict numerous components of the Tumor Microenvironment (TME) in a high-level illustration.”

Using computational algorithms and datasets from previous clinical patient care, the researchers investigated the TME.

Eduati explained

While RNA-sequencing databases are publically available, information on which patients responded to ICB therapy is only available for a limited group of patients and cancer types. So, to tackle the data problem, we used a trick.

All 100 models learned in the randomized cross-validation were included in the EaSIeR tool. For each validation dataset, we used the corresponding cancer-type-specific model: SKCM for the melanoma Gide, Auslander, Riaz, and Liu cohorts; STAD for the gastric cancer Kim cohort; BLCA for the bladder cancer Mariathasan cohort; and GBM for the glioblastoma Cloughesy cohort. To make predictions for each job, the average of the 100 cancer-type-specific models was employed. The predictions of each dataset’s cancer-type-specific models were also compared to models generated for the remaining 17 cancer types.

From the same datasets, the researchers selected several surrogate immunological responses to be used as a measure of ICB effectiveness.

Lapuente-Santana stated

One of the most difficult aspects of our job was properly training the machine learning models. We were able to fix this by looking at alternative immune responses during the training process.

Some of the researchers employed the machine learning approach given in the paper to participate in the “Anti-PD1 Response Prediction DREAM Challenge.”

DREAM is an organization that carries out crowd-based tasks with biomedical algorithms. “We were the first to compete in one of the sub-challenges under the name cSysImmunoOnco team,” Eduati remarks.

The researchers noted,

We applied machine learning to seek for connections between the obtained system-based attributes and the immune response, estimated using 14 predictors (proxies) derived from previous publications. We treated these proxies as individual tasks to be predicted by our machine learning models, and we employed multi-task learning algorithms to jointly learn all tasks.

The researchers discovered that their machine learning model surpasses biomarkers that are already utilized in clinical settings to evaluate ICB therapies.

But why are Eduati, Lapuente-Santana, and their colleagues using mathematical models to tackle a medical treatment problem? Is this going to take the place of the doctor?

Eduati explains

Mathematical models can provide an overview of the interconnection between individual molecules and cells and at the same time predicting a particular patient’s tumor behavior. This implies that immunotherapy with ICB can be personalized in a patient’s clinical setting. The models can aid physicians with their decisions about optimum therapy, it is vital to note that they will not replace them.

Furthermore, the model aids in determining which biological mechanisms are relevant for the biological response.

The researchers noted

Another advantage of our concept is that it does not need a dataset with known patient responses to immunotherapy for model training.

Further testing is required before these findings may be implemented in clinical settings.

March 26, 2018, by NCI Staff

Some people who have been treated for breast cancer or lymphoma have a higher risk of developing congestive heart failure than people who haven’t had cancer, results from a new study show.

The study researchers retrospectively compared heart failure rates in people who were diagnosed with breast cancer or lymphoma with those in people who did not have cancer. Although the risk of developing heart failure was relatively low overall, people who had been treated for cancer had more than twice the risk of developing heart failure than those who had never had cancer, they found, and the risk was evident as early as one year after their cancer diagnosis. The increased risk persisted for at least 20 years.

“As more cancer patients live longer, they are living long enough to manifest the long-term cardiac effects of cancer treatment,” said Lori Minasian, M.D., of NCI’s Division of Cancer Prevention, who was not involved in the study. “Increasingly, cardiologists and cardiovascular investigators have seen the need to evaluate the short- and long-term cardiac effects of cancer treatment.”

The bottom line, said study investigator Carolyn Larsen, M.D., of the Mayo Clinic, is that people who have been treated for breast cancer or lymphoma and their physicians should be aware of these risks, and patients should be assessed annually for signs of heart failure.

Dr. Larsen presented the study findingsExit Disclaimer at the American College of Cardiology (ACC) Annual Scientific Session on March 10.

Some Cancer Treatments Can Damage the Heart

Congestive heart failure (also referred to as heart failure) is a condition in which weakened or damaged heart muscles are unable to effectively pump blood to the rest of the body. Heart disease, diabetes, and high blood pressure are all risk factors for heart failure, as are some cancer treatments such as chemotherapy, chest radiation, immunotherapy, and some targeted therapies.

To assess the long-term risk of heart failure in people with cancer, Mayo Clinic researchers analyzed data from the Rochester Epidemiology Project. They focused on participants who were diagnosed with breast cancer or lymphoma from 1985 to 2010 and compared them with matched controls—people without cancer who were the same age and sex, and who had similar risk factors for heart disease.

Some people with breast cancer or lymphoma are “treated with therapies that can be toxic to the heart, particularly anthracyclines,” explained Dr. Larsen. Among the patients with cancer included in the analysis, nearly all had been treated with chemotherapy and 84% had received an anthracycline.

Within 5 years of their cancer diagnosis, the risk of heart failure was three times higher in people treated for breast cancer or lymphoma than in people without cancer, the researchers found. Within 20 years, 10% of the cancer survivors had developed heart failure, compared with 6% of control subjects.

The risk of heart failure was even higher for certain people with cancer. For example, people who were diagnosed with cancer at age 80 or older had three times the risk of heart failure as those who were diagnosed at a younger age. And heart failure risk was twice as high for survivors who had diabetes compared with those without diabetes.

In addition, they found that the risk of heart failure was two times higher for patients who were treated with doxorubicin (an anthracycline-based chemotherapy drug) compared with patients who received other cancer treatments.

What the Results Mean for People with Cancer

The study findings “add more information about the long-term risk after chemotherapy to the existing knowledge base and provide that data in an epidemiology study rather than a clinical trial—so the findings may be more applicable to a general population of breast cancer and lymphoma patients,” Dr. Larsen said.

Many clinical trials exclude patients with heart disease from participating, Dr. Minasian explained. Consequently, data from clinical trials may not reveal the extent to which heart failure risks are increased in those with pre-existing risk factors.

Nevertheless, Dr. Larsen stressed that “not every breast cancer or lymphoma patient is going to develop heart failure.”

Overall, 7% of those in the study treated for cancer developed heart failure, compared with approximately 3% of those in the control group. “It’s the minority” of people who develop heart failure, she said.

The researchers’ main goal, she added, “is to raise awareness of the risk of heart failure and to encourage a heart-healthy lifestyle in cancer survivors.” A heart-healthy lifestyle includes healthy eating, managing weight and stress, maintaining physical activity, and quitting smoking.

In addition, breast cancer and lymphoma survivors should be assessed for signs or symptoms of heart failure and for additional risk factors such as high blood pressure, diabetes, and smoking, Dr. Larsen said. Treating or controlling those risk factors may mitigate heart failure risk

Patients should also “be mindful that the risk of heart failure doesn’t end when they finish their cancer treatment,” Dr. Minasian added.

Ongoing Cardiotoxicity Research

Researchers are actively investigating approaches to lessen or prevent heart damage from cancer treatments. One trial—sponsored by NCI and the National Heart, Lung, and Blood Institute—is testing the cholesterol-lowering medication atorvastatin for reducing heart damage in women with breast cancer who are receiving anthracycline treatment.

Along the same lines, two studies presented at the ACC conference found that cardiac drugs may protect women with breast cancer from cardiotoxicity of cancer treatment.

In one study, the drugs lisinopril and carvedilol both prevented cardiotoxicity in women with breast cancerExit Disclaimer who were receiving the targeted therapy trastuzumab and who had been previously treated with anthracycline chemotherapy. In the other study, carvedilol reduced some measures of heart damageExit Disclaimer in women with breast cancer who were receiving anthracycline chemotherapy.

Organizations such as the ACC are also helping to better educate cardiologists and oncologists about heart failure risk factors in people with cancer “so we’re better able to take care of these patients,” Dr. Minasian said.

Earlier this year, for example, the American Heart Association published its first-ever statement on breast cancer and heart disease.

In it, the organization stressed the importance of managing cardiac risk factors in older women who have been treated for breast cancer, “because [cardiovascular disease], if not recognized and treated, can pose a greater health risk than the cancer itself.”
