The Digital 3D Heart

In medical school we frequently use books, models, and online training tools to help us understand the intricate and immensely detailed anatomy of the human body. However, these diagrams are often times 2D, and it can be difficult to fully grasp the complexity of organs. Even the cadaver lab still poses difficulty since the bodies tend to, we could say, not keep so well over the length of the course. This is why we will be examining a digital tool that will hopefully be utilized soon in medical training.    Glassworks   Inventive Medical Ltd. has partnered with Glassworks, a high-end digital animation house in Amsterdam, to bring the medical community a new tool in cardiological education. Heartworks is a computer-generated replica of the human heart, designed with incredible detail right down to each individual capillary.   This 3D simulation of cardiac anatomy can be used as a standalone teaching tool, or in conjunction with one of Inventive Medical’s training mannequins. With practical applications in transthoracic echocardiography, cardiovascular pathology, and Doppler or M-mode imaging, Heartworks offers medical students and cardiac specialists a unique way to study and perform research.

New App Analyzes Breast Cancer Treatment

It is truly amazing what apps are coming to fruition. A new app, Share the Journey, leverages Apple’s recently released ResearchKit framework that accurately and securely gathers data from participants’ devices. The app is used to analyze issues connected to breast cancer treatment. Symptoms studied include mood changes, activity and exercise disruptions, sleep disturbances, cognitive troubles, and fatigue. Using journals and survey answers solicited from program participants, in conjunction with optional iPhone sensor-collected data, the research study aims to better understand variations in post-treatment symptoms of breast cancer survivors.   With funding from the Robert Wood Johnson Foundation, and support from prominent breast cancer non-profit organizations, ShareTheJourney hopes to find ways to improve the quality of life for women diagnosed with breast cancer. All women with an iPhone, ages 18 and up, are eligible to contribute, regardless of whether they have ever suffered from the disease. To download the app from IMS Health Appscript, click...

Groundbreaking Cancer Treatment

Check out this incredible video of some new groundbreaking cancer treatments. In medical school, especially the first year, students are often exposed to a lot information that pertains to cancer, as well as some popular and commonly used drugs to treat cancer. It is always amazing to see what researchers are coming up with in modern medicine.     In a study conducted by the Royal Marsden Hospital and Institute for Cancer Research, scientists found that a combination of two melanoma treatments from Bristol-Meyers Squibb was able to halt cancer progression for up to 12 months in approximately 60% of cancer sufferers. The international trial involved 945 patients receiving a combination of two immunotherapy drugs, ipilimumab and nivolumab. James Larkin, FRCP, PhD, the UK’s Chief Investigator for numerous clinical trials in cancer-related research, says that combining these two drugs is like “taking two brakes off the immune system [sic] rather than one so the immune system is able to recognize tumors it wasn’t previously recognizing and react to that and destroy them.” (via BBC News) However, it should be noted that the occurrence of side effects such as headache, fatigue, and rash were almost doubled versus treatment with just one of the drugs.

Mummified Fetus Discovered in Living 92 Year-Old Woman’s Abdomen

Doctors in Chile discovered a calcified and over fifty-year-old fetus inside the abdomen of 92-year-old patient, according to CBS News. Local reports speculated the cause to be related to a botched abortion or lies told to the woman regarding inoperable tumor. The woman, Estela Melendez, supported the claim that she was told she had a tumor in her stomach that couldn’t be removed. The condition, lithopedion translates in Ancient Greek to mean ‘stone baby’ and occurs when a fetus dies during abdominal pregnancy and is mummified outside of the uterus. The woman’s doctors said that removing the fetus would be too dangerous of a procedure given her age and will not attempt to remove it. There are only 300 known cases of this phenomenon, the earliest of which occurred in 1554 in France. The image featured below is a photograph of a preserved calcified fetus from the Otis Historical Archives National Museum of Health and Medicine.   Check out the complete article published by CBS...

STD Testing: There’s An App for That

Nearly two million people under the age of forty have chlamydia in the United States according to the CDC and yet this disease frequently goes undetected and uncured. Since symptoms can be so minimal, without regular annual testing, many cases go undetected. When left chlamydia is left untreated, it can cause fertility or pregnancy complications for women. Gonorrhea similarly can cause infertility in both men and women or make the patient more susceptible to an HIV infection. Given these risks and statistics, Planned Parenthood has designed a new app, which has been released in California, that allows users to discreetly test for these two of the most common sexually transmitted diseases, chlamydia and gonorrhea, according to a report from NPR. Currently, any California resident over the age of 16 can use the app to purchase an STD kit for $149 that is mailed to the individual directly. After submitting a urine sample through the provided pre-paid return package, users receive their test results sent through the app in just days after mailing their sample. If any results come back positive, the app has an feature that allows users to request a prescription through Planned Parenthood or schedule an appointment for in-office antibiotic treatment. If this pilot project can expand beyond these initial stages, it could significantly help protect young men and women across the country from two dangerous, common,...

Scientists are Growing Mini Brains to Study Neurological Disorders

  Austrian researchers are growing cerebral organoids, a form of human tissue that resembles a developing brain, in order to study neurological disorders. The organoids are developed from adult fibroblasts (skin cells) and manipulated into pluripotent stem cells, able to develop into a myriad of body parts. The researchers are able to coax the stem cells into becoming neurons which they study to learn more about neurological diseases like autism or schizophrenia as well as potential cure.   Click here to read an article about this research in Technology...

Is There Such a Thing As Screening for Cancer Too Early?

Starting medical school, conversations swirl around the necessity of when and who to screen for certain diseases, such as breast cancer. Many factors play a role in these decisions such as, average age of onset of a disease, sex, race, ethnicity, geography, and more complicated factors that doctors and scientists all try to take into account when determining when screening exams should be given and who they should be given to. In particular, the necessity of breast cancer screening has been frequently debated amongst the medical community. When to screen, and who will pay for the screening, have been amongst the most hotly debated topics centered around this issue.   A recent report from NPR has found that mammograms for women in their 40s have limited value according to a review from the World Health Organization’s International Agency for Research on Cancer.  The WHO committee and the U.S. Preventive Services Task Force agreed on the limited value of mammograms for women at this age but faced serious backlash for the financial implications these reviews could have. The study that the WHO IARC is basing their conclusions on found inadequate evidence that would support mammograms for women in their forties. Following these results, the US Task Force will then review public comments and responses before making their official recommendation. Whatever the recommendation may be, Congress can still mandate mammogram coverage...
