Application of Cardio-Forecasting for Evaluation of Human—Operator Performance
The paper presents the results of the development of the cardio-forecasting technology,
which introduces a new method to monitor the state of human-operator, which is characteristic for
the given production conditions and for individual operators, to predict the moment of exhaustion
of his/her working capacity. The work aims to demonstrate the unique, distinctive features of the
cardio-forecasting technology for predicting an individual limit of his/her working capacity for
each person. A unique methodology for predicting individually for each person the moment when
he/she reaches the limit of his/her working capacity is based on a spectral analysis of a human
phonocardiogram in order to isolate the frequency component located at the heart contraction
frequency. The trend of the amplitude of this component is approximated by its model; consequently,
the coefficients of the trend model are determined. They include the operator’s operating time until
his/her working capacity is exhausted. A methodology for predicting the moment when he/she
reaches the limit of his/her working capacity for each person individually and assessment based on
this degree of criticality of their condition will be realized as a software application for smartphones

A randomized, double-blind, placebo-controlled study of an RNAi-based therapy directed against respiratory syncytial virus
RNA interference (RNAi) is a natural mechanism regulating protein expression that is mediated by small interfering RNAs (siRNA). Harnessing RNAi has potential to treat human disease; however, clinical evidence for the effectiveness of this therapeutic approach is lacking. ALN-RSV01 is an siRNA directed against the mRNA of the respiratory syncytial virus (RSV) nucleocapsid (N) protein and has substantial antiviral activity in a murine model of RSV infection. We tested the antiviral activity of ALN-RSV01 in adults experimentally infected with wild-type RSV. Eighty-eight healthy subjects were enrolled into a randomized, double-blind, placebo-controlled trial. A nasal spray of ALN-RSV01 or saline placebo was administered daily for 2 days before and for 3 days after RSV inoculation. RSV was measured serially in nasal washes using several different viral assays. Intranasal ALN-RSV01 was well tolerated, exhibiting a safety profile similar to saline placebo. The proportion of culture-defined RSV infections was 71.4 and 44.2% in placebo and ALN-RSV01 recipients, respectively (P = 0.009), representing a 38% decrease in the number of infected and a 95% increase in the number of uninfected subjects. The acquisition of infection over time was significantly lower in ALN-RSV01 recipients (P = 0.007 and P = 0.03, viral culture and PCR, respectively). Multiple logistic regression analysis showed that the ALN-RSV01 antiviral effect was independent of other factors, including preexisting RSV antibody and intranasal proinflammatory cytokine concentrations. ALN-RSV01 has significant antiviral activity against human RSV infection, thus establishing a unique proof-of-concept for an RNAi therapeutic in humans and providing the basis for further evaluation in naturally infected children and adults
