Respiratory Sinus Arrhythmia (RSA) Respiratory Sinus Arrhythmia (RSA, see RSA Training – Biotekna Plus) is the heart rate variability synching with breathing such that the “pulse-to-pulse” interval on the PPG tracing shortens when breathing in and lengthens when breathing out.It has been seen that RSA is a physiological phenomenon reflecting qualitative cardio-respiratory-circulatory interactions.Recent studies have…

Albumin is an important protein for body homeostasis. It is produced by the liver and then released into the bloodstream. It is also present in egg albumen, after which it is named. Blood albumin concentration typically ranges from 3.5 to 5.0 g/dL and accounts for approximately 60% of all plasma proteins.Albumin is the single most…

Measurement of IMAT as a predictor of outcome in patients with COVID-19 Obesity is a strong risk factor for negative outcomes in hospitalized patients with COVID-19, and fat distribution and amount of muscle mass are much more accurate risk factors than simply measuring fat mass or BMI. Recent studies have shown that body composition measurements…

On January 14, 2022, an important research was published that has allowed to objectively and instrumentally evaluate stress, chronic inflammation and their relationship with MUS (Medically Unexplained Symptoms): a whole series of persistent psychophysical disorders, including pain and discomfort. This research was conducted by using BioTekna non-invasive and rapid technologies (PPG Stress Flow® and BIA-ACC®)…

The normal metabolic processes taking place inside our body lead to continuous variations in pH in a continuous following of intake-elimination of “acids” and bases” that lead to changes in the hydrogen ion concentration with the consequent modification in the organism’s pH, which then needs to adapt to these changes and maintain the physiological pH.…

What are Medically Unexplained Symptoms – MUS? In most of the examinations carried out at General Medicine outpatient clinics, physicians focus their attention on overt clinical data, characterized by clearly recognizable symptoms. Other symptoms, which could be defined as vague, such as chronic fatigue, sleep or appetite disorders, irritable bowel or constipation, tone or mood…

Ingestion, metabolism and excretion.These are three important functions performed by two organs that are fundamental for life: the kidneys and the liver. The kidneys carry out numerous functions, including the hormonal function through the production of erythropoietin, renin and prostaglandins and ensure the elimination of nitrogenous waste (from protein metabolism) and drug waste products. The liver performs…

PRAL and buffer systems: applications High-protein diets, low consumption of negative-PRAL foods, excessive exercise, increased BMI and waist circumference, elevated levels of glucocorticoids due to excessive stress and persistent activation of the stress system (HPA – Axis index/ BIA-ACC, Biotekna), superficial breathing and/or altered respiratory rhythm and excessive intake of high-NaCl (kitchen salt) foods, such…

Changes in bone composition (T- Score BIA-ACC) from high density  through osteopenia and osteoporosis have complex, multifactorial causes and the scientific literature agrees on the beneficial impact that diet and exercise can have on bone health. Metabolic processes in our body are an extremely dynamic system, the ultimate goal of which is to maintain a…

Potassium and magnesium supplements as tools for action potential regulation Poor digestion, poor gastric emptying, alternating bowel pattern and Irritable Bowel Syndrome (IBS) are some of the Medically Unexplained Symptoms (MUS) that our body can show when the transmission of nervous impulses is altered due to ionic concentration changes (measurable with the PPG Stress Flow…
