Consider the Promises and Challenges of Medical Image Analyses Using Machine Learning

Medical imaging saves millions of lives each year, helping doctors detect and diagnose a wide range of diseases, from cancer and appendicitis to stroke and heart disease. Because non-invasive early disease detection saves so many lives, scientific investment continues to increase. Artifical intelligence (AI) has the potential to revolutionize the medical imaging industry by sifting through mountains of scans quickly and offering providers and patients with life-changing insights into a variety of diseases, injuries, and conditions that may be hard to detect without the supplemental technology. Images are the largest source of data in healthcare and, at the same time, one of the most challenging sources to analyze. Clinicians today must rely mainly on medical image analysis performed by overworked radiologists and sometimes analyze scans themselves. The interpretations of medical data are being made mostly by a medical expert. In terms of image interpretation by a human expert, it is entirely limited given its subjectivity, the complexity of the image, the extensive variations that exist across different interpreters, and fatigue. Despite constant advances in the medical imaging space, almost one in four patients experiences false positives on image readings. This can lead to unnecessary invasive procedures and follow-up scans that add cost and stress for patients. And while false negatives happen less often, the impact can be catastrophic. The surprisingly high rate of false ...

Authors: Musio F Abstract INTRODUCTION: Anemia has and will continue to be a central theme in medicine particularly as clinicians are treating a burgeoning population of complex multi-organ system processes. As a result of multiple randomized controlled trials (RCTs), meta-analyses, and societal recommendations overly restrictive paradigms and under-administration of erythropoiesis stimulating agents (ESAs) have likely been followed by clinicians among all specialties. AREAS COVERED: A review of anemia in the context of chronic kidney disease, hematologic malignancies and cancer is presented with focus on the e...

Authors: Sabet Sarvestani F, Azarpira N Abstract Heart and cerebral infarctions, as two important ischemic diseases, lead to the death of tissues due to inadequate blood supply and high mortality worldwide. These statuses are started via blockage of vessels and depletion of oxygen and nutrients which affected these areas. After reperfusion and restoration of oxygen supply, more severe injury was mediated by multifaceted cascades of inflammation and oxidative stress. microRNAs (miRNAs) as the regulator of biological and pathological pathways can adjust these conditions by interaction with their targets. Also, miRNAs...

CONCLUSIONS: Immunohistochemistry seems to be a promising option not only in clinical recognition, but also in the selection and monitoring of treatment effects. However, these methods have not yet recommended for routine clinical use. PMID: 33032462 [PubMed - as supplied by publisher]

Authors: Matti B, Zargar-Shoshtari K Abstract Prostate cancer represents a significant health burden worldwide. The cancer incidence had substantially increased since the introduction of prostate specific antigen (PSA) in cancer screening. This had led to considerable debates among health professionals and epidemiologists, since PSA as a screening tool seemed to be far from perfect. In New Zealand, the controversy was quite prominent in the last three decades, with some advocating the benefits of screening, while others concerned regarding the risk of harms. With the absence of an organised screening programme and ...

CONCLUSION: This study found that childhood cancer survivors in New Zealand had a high prevalence of developmental dental abnormalities and it identified potential risk factors related to their cancer treatment. Inequitable access to oral rehabilitation for this patient group argues for a mechanism for consistent improved access to publicly funded dental care across district health boards in New Zealand.

When it comes to emergency care, you may have a tough time if you're in pain and not a white man.  Previous research has shown that black and Hispanic patients who reported severe pain in the the ER were 22 percent less likely to receive pain medication than white patients who presented with the same complaints. And women suffer similar disparities: A 2008 study found that women wait an average of 16 minutes longer to receive pain relief for acute abdominal pain in the ER than men do. Now a new study is shedding some light on this phenomenon. "We’ve been looking at racial bias and pain perception ...

By STEVE FINDLAY Earlier this month the Center for Public Integrity (CPI) published a sharp-edged piece on PCORI—the Patient-Centered Outcomes Research Institute.  The piece raised some salient issues and it’s timely to take stock of PCORI at the half way point of its authorized funding.  (Unless renewed, PCORI sunsets in 2019.)  The Affordable Care Act created PCORI as an independent nonprofit (non-government) entity.  But PCORI’s funding and structure makes it more or less quasi-government.  It gets its money from the Medicare trust fund, treasury general funds, and a tax on pr...

In a recent paper, Soneji and Yang revisit a topic we first explored in the April 2012 issue of Health Affairs — namely, whether the U.S. gets value for its cancer care. We found that life expectancy after cancer diagnosis rose more quickly for patients in the U.S. than for patients in Europe. Moreover, while spending per patient also rose more quickly in the U.S., Americans still received good value from the health care system. Compared to the gains seen in Europe, for example, each additional life-year gained in the U.S. cost roughly $20,000 in additional U.S. spending. Soneji and Yang re-examine trends in cancer d...
