Since past 10 years there has been a dramatic rise in the proportion of cataract surgeries performed at ambulatory surgery centers. Certain communities prefer their cataract surgeries in a surgery center rather than a hospital. The individuals preferred less expensive ambulatory surgery centers so that care may be delivered faster. While there was an increase in the expensive ambulatory surgeries, the researchers from the University of Michigan Kellogg Eye Center wanted to find its safety. Thus they reviewed the data of 369,320 enrollees (age ≥40 years) worldwide to find the difference in the safety between hospitals and surgery centers . The study is published in the JAMA Ophthalmology .
Hypoxia-ischemia is a serious complication in which restricted blood flow deprives the brain of oxygen. The lack of oxygen levels results into brain injury and its consequences gradually affects the entire lifespan and sternness ranges from mild to severe. A maternal/placental problem, such as placental abruption or cord prolapse, can cause complications during or before birth. Fetal/newborn issues, such as asphyxia due to labor difficulties, infection, and fetal-maternal bleeding or twin-to-twin transfusion can also cause complications.
A new study led by Alexandra Ycaza Herrera at the USC Leonard Davis School of Gerontology, suggests that estrogen therapy after menopause enhance the memory that is required for short-term cognitive tasks from the effects of stress.On combining estrogen and progesterone in the therapy, the researchers observed an increased risk of breast cancer, stroke, heart disease, and blood clots. However, the potential risks of the therapy were highlighted in the previous studies. The study findings are published in the Journal of Clinical Endocrinology and Metabolism .
Erythropoiesis is a complicated process in which red blood cells are formed from haematopoietic stem cells in the bone marrow. A research team led by Assistant Professor Rajesh Chandramohanadas at Singapore University of Technology and Design (SUTD) is now able to explain this fascinating biological phenomenon. The mystery behind the red blood cells maturation published in the British Journal of Haematology solved through quantitative profiling of protein composition and imaging.
The researchers have moved one-step forward in examining a scalpel-free surgery in Parkinson tremor treatment. They determined the improvement of tremors caused by Parkinson's disease using focused ultrasound, which produced encouraging results. The findings were published in the scientific journal JAMA Neurology and further research is warranted.
Ear infections are common but do not require a course of antibiotics. In treating pain, a better alternative in most cases of middle ear infection are over-the-counter painkillers such as paracetamol and ibuprofen, said draft guidance from the National Institute for Health and Care Excellence (NICE).
The research carried by the Christina Blomdahl, a licensed occupational therapist and art therapist, involved 43 patients who were suffering from severe to moderately severe depression. The patients were exposed to a manual-based art therapy. The control group consisted of 36 participants suffered from the same medical condition. Most of the patients were unable to work as they were severely depressed.
A new study published in the recent issue of the journal Neurology: Neuroimmunology & Neuroinflammation revealed that MRI scans to find the changes in the brain in children with high risk of developing multiple sclerosis (MS) before the clinical symptoms of the disease appear, might lead to earlier diagnosis and treatment.
According to the research published in the Journal of Epidemiology & Community Health, heavy drinking and smoking are linked to visible signs of physical aging. Light-moderate drinking not associated with looking older than one's years.
Senolytic agents target senescent cells. These are cells have stopped dividing and that damage adjacent cells by secreting toxic chemicals. Senescent cells accumulate with age, which is linked to other chronic conditions (including diabetes, cardiovascular disease, most cancers, dementia, arthritis, osteopetrosis, and frailty). According to Mayo Clinic aging experts, if senolytic drugs are proven to effective and safe in humans, they will be "transformative" by preventing or delaying chronic conditions as a group instead of one at a time.
A new optical brain-imaging tool, the Imagent, provides a never-before-seen look inside the head using lasers and photodetectors. The non-invasive tool estimates and measures infrared light which is projected into the brain and the frequency at which it exists, providing a picture of brain activity and blood flow at the same time.
