Why Food Allergies May Be Increasing

Food allergies have become more common these past few years in both adults as well as children. Allergies are defined as the immune system’s overreaction to an antibody known as immunoglobulin E. This protein is usually produced by the immune system to help detect and attack invaders. When the body identifies a threat, it triggers histamine production, which in turn prompts an allergic reaction in an effort to eliminate the threat. You may notice that when an individual is reacting to something, their skin may itch and their tissues inflame; they may also wheeze, sneeze or cough. Data from the…

Researchers Discover New Way to Noninvasively Monitor Immune Cells Inside Tumors

Scientists have designed a new strategy to noninvasively track macrophages in tumors in the breast and brain. Macrophages are immune cells that play a crucial role in the immune system, carrying out a number of functions, including clearing out dead cells and digesting microorganisms. These cells are often recruited by cancer to increase resistance to treatment and support tumor growth. The Ludwig Cancer Research study, led by Davide Croci and Johanna Joyce, also involved their colleague Ruud B. van Heeswijk from the Lausanne University Hospital. Joyce stated that monitoring tumor-associated macrophages had the potential to substantially improve how various cancers…

Study Finds Smart Watches Can Accurately Detect Atrial Fibrillation

New research has found that smart watches can be used to detect atrial fibrillation accurately using an electrocardiogram application. Atrial fibrillation is an irregular heart rhythm that may cause blood clots. It also heightens an individual’s risk of heart failure and stroke, among other heart-related complications. The research, which was conducted earlier this year, discovered that the Apple Watch could be used to diagnose this arrhythmia. For their study, the researchers looked into the accuracy of this device when testing individuals who had abnormal electrocardiograms. The lead author of the study, Dr. Marc Strick, stated that this technology was widely…

Researchers Develop Wireless Implant to Kill Cancer Cells in Brain Tumors

Glioblastoma is a deadly and aggressive type of cancer that develops in an individual’s brain or spinal cord. This fatal cancer, which has a 15-month median survival time, claims the lives of more than 10,000 Americans annually. Treatment for brain tumors usually involves surgery to remove as much of the tumor as possible. Surgery is then followed by radiation or chemotherapy, which involves many visits to the hospital and severe side effects. Now, scientists at Stanford Med may have developed a new way to treat brain tumors. They have designed a small wireless implant that can treat patients with brain…

New Experimental Drug May Reverse Brain Damage Caused by Concussions

New research has discovered new information about how an experimental medication reverses neural damage linked to traumatic brain injuries. This discovery lays the foundation for a drug, which could help prevent the cognitive deficit that occurs after a concussion, to be developed in the future. The research was carried out by a team of scientists at the University of California, San Francisco. The primary objective of the research was to explore the integrated stress response signaling pathway. Environmental stresses usually trigger this pathway, often causing facilities that produce proteins in the cells to shut down. For their study, the researchers…

Study Finds Livers with a Cumulative Age of 100 Years

Scientists from University of Texas Southwestern Medical Center, Dallas, and Andover, Massachusetts and TransMedics have discovered that there are transplanted livers that have a cumulative age exceeding one hundred years. The team of scientists studied those livers in order to find out why they were so resilient. They presented their discoveries at the 2022 Scientific Forum of the American College of Surgeons Clinical Congress. For their research, the scientists used the UNOS STAR file to locate livers that had a cumulative age equal to or exceeding one hundred years. They discovered that of the total number of livers transplanted in…

Patient Plays Sax During Lengthy Surgery to Remove Brain Tumor

Last week, a musician had his brain tumor removed while fully conscious during a nine-hour surgery that took place in Italy. During the operation, which was carried out at the Paideia International Hospital in Rome, the 35-year old musician played his saxophone. This helped the surgeon map out different functions of the brain as he operated. Dr. Christian Brogna, the neurosurgeon who performed the operation, stated in an interview that there were no negative effects observed in the patient after the tumor was successfully removed. Brogna led a team of highly qualified specialists during the operation, which used state-of-the-art technology.…

New Research Finds Gaming Can Cause Fatal Arrhythmias

A new case-series study has discovered that gaming can trigger deadly heart arrhythmias in children. Heart arrhythmias are irregular heartbeats that occur when the electrical signals coordinating the beating of an individual’s heart aren’t working properly. The researchers stated that children who fainted while they played video games needed to be evaluated. They also urged physicians to be aware of this possible risk in children with arrhythmia syndromes while gaming. Dr. Christian Turner, one of the leads of the study, stated that the population at risk was unusually small and if there was no suspicious family history, then no cardiac…

Cancer Studies Provide Researchers with New Information on Ovarian Cancer Development, Growth

Two studies recently conducted by Cedars-Sinai Cancer scientists have discovered new information that may improve the understanding of why some patients don’t respond to treatment and what drives ovarian cancer development. Epithelial ovarian cancer is the most common ovarian cancer type, developing in the epithelial tissue. It is estimated that roughly 85% of ovarian tumors are epithelial. The first study affords researchers a better understanding into how ovarian tumors develop resistance to treatment. Resistance usually develops in nearly 80% of high-grade serous tumors of patients with ovarian cancer. The co-first author for this study, Michelle Jones, stated that whole genome…

Researchers Develop AI Tool That Scans Retina, Detects Heart Disease in One Minute

Heart disease, which is estimated to take around 17.9 million lives annually, is among the leading causes of death across the world. This condition commonly affects people aged 20 and older across the united States, with one American suffering a heart attack every 40 seconds. In total, roughly 800,000 individuals suffer heart attacks every year. Although heart diseases such as coronary artery disease cannot be cured, early detection can allow for the management of symptoms to reduce a patient’s chances of having a heart attack. Researchers have now developed software that could allow physicians to detect heart disease in only…
