New Study Challenges Existing Theories about Alzheimer’s Disease

Alzheimer’s is a debilitating mental illness that affects more than 6 million Americans of all ages. The condition is especially prevalent among the elderly, with an estimated 6.5 million Americans aged 65 and older living with Alzheimer’s last year. Some figures show that 73% of the people living with Alzheimer’s are 75 years old and older. Alzheimer’s usually occurs when amyloid proteins build up abnormally in and around brain cells and form deposits of plaque, causing a reduction in neurotransmitter activity. The plaque buildup causes parts of the brain to shrink over time, usually beginning with the regions in charge…

Scientific Review Highlights Stigma Directed at People Living with Chronic Pain

The International Association for the Study of Pain estimates that 20% of people worldwide live with chronic pain, with low- and middle-income countries reporting a higher chronic pain prevalence of around 33%. A recent scientific review by researchers from the Sapienza University of Rome has now revealed that chronic pain sufferers are increasingly becoming victims of stigma. Stigma is defined by the World Health Organization (WHO) as a mark of disgrace, shame or disapproval that results in discrimination and exclusion from the community. When patients suffer from stigmatized conditions such as HIV/AIDS, obesity, and chronic pain, they are much less…

America Faces Shortage of Infectious Disease Experts

The United States is currently facing a critical shortage of infectious disease experts. Infectious disease doctors, or IDs as they are commonly referred to in hospitals, are usually tasked with diagnosing diseases and guiding hospital teams in treatment. This tends to involve collecting extensive and detailed medical histories and reviewing past medical records thoroughly to identify the root cause of a patient’s symptoms. Unsurprisingly, this infectious disease expert work requires a tremendous amount of cognitive effort and plays a critical role in the proper diagnosis and treatment of patients. It also requires key qualifications, with ID doctors having to go…

Why a Dog’s Teeth May Chatter

Similar to humans, animals such as dogs have unique behaviors they exhibit from time to time. While most quirks are adorable, teeth chattering may be caused by severe underlying issues. To help you understand why your dog’s teeth are chattering, below we look at reasons why that may happen. Your dog is cold Your dog’s teeth may chatter when it is in a cold environment. This shows that the animal is not comfortable with the current temperature, so if it is outside, you should bring your pet inside. Alternatively, if an animal’s teeth are chattering while inside the house, then…

Four Developments in Cancer Research That Occurred in 2022

Cancer is a leading cause of death globally, with cancer types such as lung cancer, breast cancer and colorectal cancer being responsible for most cancer deaths. Over the last year, research in this particular field has made significant strides. Below, we look at some of the developments that occurred in 2022. CAR T-cell therapy proving to be revolutionary The FDA first approved the first CAR T-cell immunotherapy in 2017. Since then, the technology has shown great promise in the treatment of various cancers. Chimeric antigen receptor (CAR) T-cell therapy usually involves genetically engineering an individual’s immune cells to better identify…

New Treatment Approach for Cancer Combines Bacterial, Pharmaceutical Therapy

Lung cancer is the deadliest type of cancer in the United States, causing more than 100,000 deaths annually, which is more casualties than other kinds of cancers combined. Current lung-cancer treatments include chemotherapy, surgery, targeted therapy, radiation therapy or a combination of these approaches. Treatment can be up to 90% effective if the cancer is still small and in early stages, but success rates drop as the tumor becomes larger and more advanced. As the risk of cancer in people under age 50 has increased dramatically, scientists across the country have dedicated their time and energy to discovering even more…

Study Finds Smoking Linked to Mid-Life Cognitive Decline, Confusion

Researchers at The Ohio State University have discovered that middle-aged smokers have a higher likelihood of experiencing confusion and memory loss in comparison to their nonsmoking counterparts. The study, which is the first to look into the link between cognitive decline and smoking, has also found that the likelihood of cognitive decline is lower in individuals who stopped smoking. The researchers were also focused on determining whether this link was modified by gender at birth. Their findings build on prior studies that established links between smoking and forms of dementia such as Alzheimer’s disease. For their study, the researchers used…

Research Discovers Bidirectional Link Between Lower-Back Pain, Insomnia

Most people experience lower-back pain at some point in their lives, be it as a result of injury, chronic back issues, pregnancy, periods and other underlying physiological issues. Prior studies have found links between lower-back pain and a range of psychological and social factors, including body weight, gender, mood disorders and smoking habits. Despite this, identifying the origin of lower back pain is still challenging. Now, a new study has linked lower-back pain to sleep disturbances and insomnia. Insomnia is a common sleep disorder that makes it hard for individuals to stay asleep or fall asleep. The study, which was…

New Research Shows Brain Stimulation Improves Reading Ability of Macular Degeneration Patients

Macular degenerative disease is one of the leading causes of vision loss in older adults across the world. It is characterized by loss of central vision as part of the inner layers of the retina that facilitate clear vision steadily break down. Around 20 million adults in America are estimated to live with some kind of age-related macular degeneration (AMD), with adults aged 75 and above having a 30% risk of developing the disease. The condition makes it extremely frustrating and difficult to read, forcing many AMD patients to give up on reading altogether. However, a study from the University…

Machine Learning Effort Enables Large-Scale Cancer Study to Improve Boundary Detection

Scientists at the University of Pennsylvania School of Medicine and Intel Corp. carried out a large-scale international machine learning effort to collect knowledge from brain scans of more than 6,000 patients with glioblastoma at various sites globally. Their objective was to develop a model that could improve identification and prediction of boundaries in different tumor subcompartments. Spyridon Bakas, an assistant professor at Penn Medicine, stated that the study had the single biggest and most-diverse glioblastoma patient dataset ever considered in the literature, noting that this was facilitated through federated learning. Bakas also noted that the machine learning models became more…
