New biomarkers of inflammation identified as risk of polyneuropathy

Polyneuropathy is one of the most common complications in people with diabetes. However, it can also occur with certain risk factors or diseases before the onset of diabetes. First symptoms are often pins-and-needles sensations in the feet. Although polyneuropathy is present in about 30 percent of people with diabetes, it often remains undiagnosed. Scientists from the German Diabetes Center (DDZ) in Düsseldorf, in cooperation with colleagues from Helmholtz Zentrum München (HMGU), both partners in the German Center for Diabetes Research (DZD), have now shown for the first time that six biomarkers of inflammation indicate the risk of polyneuropathy. The results were published in the current issue of the journal Diabetes.

The influence of genetics on nutritional requirements

Approximately 0.1%: that is the average genetic difference between two individuals. This small percentage is responsible for the variations of certain physical traits, such as eyes, hair, and height, but also for differences in our susceptibility to certain diseases and our capacity to absorb vitamins and phytomicronutrients (carotenoids, polyphenols, etc.), involved in the prevention of chronic disease. Based on the study of genetic interindividual variability, researchers from INRA and Aix-Marseille University have published a review on current knowledge of nutrigenetics in the Annual Review of Nutrition on 21 August 2018. The objective of this emerging science is to personalize nutritional recommendations in order to optimize nutrient, micronutrient, and phytomicronutrient allowances by taking into account genetic differences between individuals and groups of individuals.

Menopause contributes to a decline in muscle strength - a crucial factor of functional independence in old age

Menopause occurs on average at 51 years of age and leads to the gradual dysregulation of the reproductive endocrine system. The menopausal transition can be divided roughly into three different stages. During pre-menopause, the menstrual cycle gradually becomes irregular. This stage begins 5-10 years before menopause. Perimenopause is the transition period prior to menopause, when the function of the ovaries noticeably fades away leading to cessation of menstruation. Postmenopause is the time after the last menstruation.

New nusinersen drug delivery method identified for spinal muscular atrophy patients

STRASBURG, PA- A new report has identified an alternative method to deliver nusinersen to patients with spinal muscular atrophy (SMA) using a subcutaneous intrathecal catheter system (SIC) configured by connecting an intrathecal catheter to an implantable infusion port. SMA is a devastating genetic disease that leads to progressive degeneration of motor neurons that control movement, swallowing, and breathing. It is the leading genetic cause of infant death worldwide. Nusinersen is the first FDA approved therapy for SMA but must be administered into the cerebrospinal fluid by repeat lumbar puncture every 4 months for life. Unfortunately, the majority of surviving SMA patients have skeletal deformities or spinal hardware that make it difficult to safely and reliably access the cerebrospinal fluid.
