"Since its appearance in late 2019, COVID-19 has caused well over one million deaths worldwide. Large-scale testing and contact tracing remain critical for controlling viral spread. Complying with the US CDC and WHO protocols for sample collection requires a ready supply of inexpensive swabs and collection reagents. Unfortunately, CDC-approved clinical-grade sampling supplies are expensive, and additionally, current methods prevent further analysis of the microbiome due to the presence of antibiotics in viral transport media. Researchers sought out new testing supplies in a recent study comparing five consumer-grade swabs and one clinical-grade swab. They found that using 95% ethanol instead of viral transfer media reduced RNase activity, preserving samples for microbiome analysis, and extracting directly from the swab head instead of the surrounding liquid resulted in 2-4x higher RNA recovery than the clinical standard..."

Diseases Exposed: ESR Test in the Classroom
Read the Fine Print
Educational Use
Rating
0.0 stars

Students demonstrate the erythrocyte sedimentation rate test (ESR test) using a blood model composed of tomato juice, petroleum jelly and olive oil. They simulate different disease conditions, including rheumatoid arthritis, anemia, leukocytosis and sickle-cell anemia, by making appropriate variations in the particle as well as in the fluid matrix. Students measure the ESR for each sample blood model, correlate the ESR values with disease conditions and confirm that diseases alter blood composition and properties. During the activity, students learn that when non-coagulated blood is let to stand in a tube, the red blood cells separate and fall to the bottom of the tube, resulting in a sediment and a clear liquid called serum. The height in millimeters of the clear liquid on top of the sediment in a time period of one hour is taken as the sedimentation rate. If a disease is present, this ESR value deviates from the normal, disease-free value. Different diseases cause different ESR values because blood composition and properties, such as density and viscosity, are altered differently by different diseases. Thus, the ESR test serves as a real-world diagnostic screening test to identify indications of the presence of any diseases in people.

Evaluation of diagnostic tests

A diagnostic test is an objective method of deciding whether an animal has a disease, or not. Decisions made following diagnostic testing are usually dichotomous e.g. treat or do not treat the animal, therefore diagnostic tests are usually interpreted as dichotomous outcomes (diseased or non-diseased). In this case, if a diagnostic test is measuring a continuous outcome e.g. antibody titre then a cut-off for classifying animal’s as positive or negative must be selected. The figure below shows that whereever the cut-off is selected there is usually some overlap between results i.e. some diseased animals will have the same value as non-diseased animals and resulting in some false-positive and false-negative results.

It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Congenital heart defects affect approximately 1% of all babies born each year and account for almost 20% of all newborn deaths. Early diagnosis while still in the womb can greatly improve an affected baby’s chance of survival. Unfortunately, diagnosis relies exclusively on ultrasound imaging, where accurate readings aren’t guaranteed. Researchers in Japan are tackling this problem by enlisting the help of artificial intelligence. More importantly, they’re helping the doctors entrusted with patient care to understand how AI programs spot heart defects. Advancements in artificial intelligence have improved how congenital heart defects are diagnosed. Ultrasound videos of fetal hearts beating normally and others with structural defects can be studied with AI, which can then determine whether the fetal hearts in new videos are abnormal or not..."

Abnormal Psychology is an Open Education Resource written by Alexis Bridley, Ph.D. and Lee W. Daffin Jr., Ph.D. through Washington State University. The book tackles the difficult topic of mental disorders in 15 modules. This journey starts by discussing what abnormal behavior is by attempting to understand what normal behavior is. Models of abnormal psychology and clinical assessment, diagnosis, and treatment are then discussed. With these three modules completed, the authors next explore several classes of mental disorders in 5 blocks. Block 1 covers mood, trauma and stressor related, and dissociative disorders. Block 2 covers anxiety, somatic symptom, and obsessive-compulsive disorders. Block 3 covers eating and substance-related and addictive disorders. Block 4 tackles schizophrenia spectrum and personality disorders. Finally, Block 5 investigates neurocognitive disorders and then ends with a discussion of contemporary issues in psychopathology. Disorders are covered by discussing their clinical presentation and DSM Criteria, epidemiology, comorbidity, etiology, and treatment options.

"Whether it be MRI, CT, or PET scans, nearly every cancer patient undergoes some form of imaging. These images provide important information about the location and stage of tumor growth and can, therefore, inform treatment strategies. But recent advances in Artificial Intelligence make it possible to mine these images for even more data. This emerging field, called ‘radiomics’ aims to utilize the full potential of medical images by extracting high-dimensional data to objectively characterize and monitor individual tumors. Many current cancer-detection and diagnostic techniques rely on invasive approaches such as tissue biopsies. But these practices have both high risk and high cost. Radiomics, on the other hand, offers a promising method to gather important information about tumors -- such as size, shape, and texture -- in a non-invasive and often cost-effective manner..."

The video's transcript is also provided in full, with a portion provided below for preview:

"A recent study published in the British Journal of Nutrition suggests that enterolactone, an estrogen-like compound formed by the breakdown of whole grains and other plant-based foods by gut bacteria, could protect against the risk of death due to colorectal cancer—at least, for women. For men, just the opposite could be true: high concentrations of the compound might actually increase that risk. The findings, published as part of a special issue on nutrition and cancer, point to a potentially significant link between diet and survival after colorectal cancer that warrants a much closer look by researchers. The authors of the study reached those conclusions by examining data from the “Diet, Cancer and Health” study, an ongoing cohort study of older men and women in Denmark. Specifically, they compared the death outcomes of people with varying levels of enterolactone in their blood plasma, before being diagnosed with colorectal cancer..."

It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Glioblastoma multiforme (GBM) is a deadly brain cancer that affects both adults and children. GBM remains mostly incurable because of the nonuniform nature of GBM cells and the numerous mechanisms involved. However, noncoding RNA molecules called circular RNAs (circRNAs) may be valuable targets for GBM treatment, because these molecules can promote or suppress cancer-related processes like cell proliferation, cell death, invasion, and chemoresistance. For example, various circRNAs can regulate pathways that are dysregulated in GBM, such as the PI3K/Akt/mTOR, Wnt/β-catenin, and MAPK pathways. Other circRNAs can positively or negatively regulate tumor blood supply establishment and metastasis to influence GBM progression. CircRNAs are stable and present in numerous body fluids, and some are associated with tumor grade and outcomes, making them promising biomarkers. In addition, silencing or overexpressing certain circRNAs in patients may help treat GBM or improve patients’ responses to other treatments..."

It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Hepatocellular carcinoma (HCC) is the fourth leading cause of cancer-related death worldwide. Despite advancements in HCC diagnosis and treatment, current staging systems lack specificity and can’t easily predict patient survival. Researchers now report a new prognostic and diagnostic approach based on tracking genes that control iron metabolism in the body. Iron is critical for normal cell metabolism, growth, and proliferation. That goes extra for tumor cells, which have an increased demand for iron. But too much iron can lead to cell death—a process known as “ferroptosis”—which some researchers are harnessing to eliminate harmful cancer cells. In the current study, researchers used high-throughput sequencing to identify genes associated with iron metabolism and ferroptosis in patients with HCC. Based on four genes, patients could be divided into a low-risk group and a high-risk group with poorer overall survival and HCC samples could be distinguished from normal samples..."
