161 Biosensor in cardiology. T-care project: a preliminary study on innovative wearable non-invasive telemonitoring system

The demographic trend evolution and the modification of health needs highlight the requirement for a novel organization of the healthcare system. Telemedicine is a technological tool that allows a knockdown of geographic barriers being useful in the management of remote patient assistance. Telemedicine is roughly applied in different cardiology’s areas, from telemetric to implantable devices (loop recorders) in order to monitor cardiac rate, cardiac rhythm variations, and the onset of arrhythmic events. The aim of the present study is to assess the validity of wearable devices (T-shirt equipped with biosensors and bands with photopletimographic system) in monitoring EKG, cardiac rate, and pulse oximetry. We enrolled 38 patients, 25 of whom admitted to the Cardiology Unit, University of Bari. Main characteristics of the sample are listed in Table 1. The difference between traditional monitoring system and wearable biosensors in not statistically significant as shown in Figure 1; therefore the devices tested in this study show a satisfying level of reliability in monitoring cardiac rate, pulse oximetry, QT interval, QRS complexes, and onset of arrhythmic events. However, alerts produced by arrhythmias different from atrial fibrillation are not completely reliable; moreover, the software and the diagnostic algorithm need to be optimized for motion artefacts. For these reasons, results need to be reproduced on a large cohort of patients.

A Review of Carpal Tunnel Syndrome and Its Association with Age, Body Mass Index, Cardiovascular Risk Factors, Hand Dominance, and Sex

Carpal tunnel syndrome (CTS) is one of the most common compressive, canalicular neuropathies of the upper extremities, causing hand pain and impaired function. CTS results from compression or injury of the median nerve at the wrist within the confines of the carpal tunnel. Parameters such as age, sex, and body mass index (BMI) could be risk factors for CTS. This research work aimed to review the existing literature regarding the relationship between CTS and possible risk factors, such as age, sex, BMI, dominant hand, abdominal circumference, respiratory rate, blood pressure, and cardiac rate to determine which ones are the most influential, and therefore, take them into account in subsequent applied research in the manufacturing industry. We performed a literature search in the PubMed, EBSCO, and ScienceDirect databases using the following keywords: carpal tunnel syndrome AND (age OR sex OR BMI OR handedness OR abdominal circumference OR respiratory rate OR blood pressure OR cardiac rate). We chose 72 articles by analyzing the literature found based on selection criteria. We concluded that CTS is associated with age, female sex, and high BMI. Trends and future challenges have been proposed to delve into the relationship between risk factors and CTS, such as correlation studies on pain reduction, analysis of weight changes to predict the severity of this pathology, and its influence on clinical treatments.

Anticoagulation in atrial fibrillation

Atrial fibrillation is the most common sustained disturbance of cardiac rhythm. It is a global epidemic and an evolving problem in cardiovascular medicine. Atrial fibrillation is an independent risk factor for embolic stroke, increasing the risk of stroke five-fold. Despite good evidence for the reduction of stroke risk with anticoagulant therapy, there is significant under treatment. Anticoagulant prescribing is frequently discordant with all current guidelines and decision aids with both over and under use of oral anticoagulants. It is important that GPs have up-to-date knowledge about atrial fibrillation in terms of both its diagnosis and management, and that patients have an understanding of anticoagulant medication. This article aims to update knowledge about atrial fibrillation, the use and benefits of anticoagulation with insights on some barriers to anticoagulation in primary care. This article does not cover management of atrial fibrillation with control of cardiac rate or rhythm to maintain cardiac function.

Nonclinical Safety and Toxicokinetics of MnTnBuOE-2-PyP5+ (BMX-001)

BMX-001, a manganese porphyrin that has anti-inflammatory, antioxidant, and antitumor properties, is being developed as a potential therapeutic for high-grade glioma (HGG) and head and neck (H&N) cancer. An IND has been opened for BMX-001 in the treatment of HGG (NCT02655601) and another is in preparation for H&N. The safety of BMX-001 has been evaluated in a battery of nonclinical Good Laboratory Practice (GLP)-compliant studies. Systemic toxicity has been evaluated using the intended cGMP product administered subcutaneously for periods of up to 5 weeks in both the mouse and the monkey and included toxicokinetic evaluations to characterize systemic exposure and tissue distribution and clearance of BMX-001. In additional GLP studies, BMX-001 was not irritating to the skin or eye and caused no changes in cardiac rate or rhythm or blood pressure. Mixed results for genotoxicity were seen with the weight of evidence indicating that BMX-001 poses no genotoxic risk in humans. In systemic mouse and monkey studies, loading/maintenance dose no observed adverse effect levels were 12/2 mg/kg/dose and 6/2 mg/kg/dose, respectively, with maintenance doses administered every 3 days after the initial loading dose. Systemic data were used to determine a Food and Drug Administration-approved safe starting dose for the initial clinical study in patients with HGG. BMX-001 was detected in analyzed tissues, including the brain, persisting well past the short plasma clearance period. The highest levels of BMX-001 were seen in the liver and kidneys, with amounts in these tissues returning to close to undetectable levels after a 2-week cessation of dosing.
