Vasomotor assessment by camera-based photoplethysmography

AbstractCamera-based photoplethysmography (cbPPG) is a novel technique that allows the contactless acquisition of cardio-respiratory signals. Previous works on cbPPG most often focused on heart rate extraction. This contribution is directed at the assessment of vasomotor activity by means of cameras. In an experimental study, we show that vasodilation and vasoconstriction both lead to significant changes in cbPPG signals. Our findings underline the potential of cbPPG to monitor vasomotor functions in real-life applications.

This article explores commonly discussed theories of violent video game effects: the social learning, mood management, and catharsis hypotheses. An experimental study was carried out to examine violent video game effects. In this study, 103 young adults were given a frustration task and then randomized to play no game, a nonviolent game, a violent game with good versus evil theme (i.e., playing as a good character taking on evil), or a violent game in which they played as a “bad guy.” Results indicated that randomized video game play had no effect on aggressive behavior; real-life violent video game-playing history, however, was predictive of decreased hostile feelings and decreased depression following the frustration task. Results do not support a link between violent video games and aggressive behavior, but do suggest that violent games reduce depression and hostile feelings in players through mood management.

Teaching Statistics

This study attempts to determine whether gamification can be used as a pedagogical technique to overcome the challenges in teaching statistics. A post-test quasi-experimental design was carried out in gamified and non-gamified groups in order to reveal the effect of gamification elements in cultivating students’ statistical literacy skills. Students in gamified group were also interviewed to understand the function of gamification process. The results suggest that; although gamifying the instructional process had a positive impact on developing students’ statistical literacy in medium and high score students; surprisingly the influence of the gamification to the low- achieved scores were not positive. The positive impact was discussed in accordance with the gradual structure of statistical literacy and suggestions for successful gamification applications due to the context were included.

Resting Heart Rate

Purpose: Resting heart rate (HR), health related quality of life (HQoL) and NYHA functional capacity are referred as important determinants of prognosis and targets of therapy in heart failure (HF). REALITY HF (Resting Heart Rate and Real Life Treatment Modality in Outpatients with Left Ventricular Systolic Dysfunction) study data were analyzed for the evaluation of any relationship of resting HR with HQoL assessed by Kansas City Cardiomyopathy Questionnaire (KCCQ) and NYHA functional class. Methods: REALITY HF was a multicenter, prospective registry designed to evaluate HF patients’ characteristics and effects of treatment modalities on resting HR and enrolled 1057 patients (age 61±12 years) with LVEF <40%. 781 (74%) patients in sinus rhythm were included in this analysis. Patients were classified into 4 groups according to the quartiles of HR: Q1:<68 bpm (n=234), Q2:69-75 bpm (n=189), Q3:76-87 bpm (n=194) and Q4:>87 bpm (n=164). KCCQ was completed in a random sample of 320 (Q1:n=27, Q2:n=99, Q3:n=125, Q4:n=69) patients, in which higher scores show better patient’s health status. Results: During enrollment, 82% of patients were receiving ≥2 drugs including ACE[[Unable to Display Character: İ]]/ARB, beta blocker, aldosterone blocker, diuretic or digoxin. Resting HR was 76±14 bpm and 68% of patients had a resting HR ≥70 bpm. KCCQ overall summary score (OSC) was found to be 75.7±13.2 in those in Q1, 65.5±20.8 in Q2, 64.4±20.6 in Q3 and 58.3±21.2 in Q4 (p=0.004) and KCCQ clinical summary score (CSS) was 80.4±15.7 in those in Q1, 70.0±22.4 in Q2, 69.9±21.9 in Q3 and 63.8±23.3 in Q4 (p=0.016). Also, there was a significant negative correlation between resting HR and OSC (p=0.008) or CSS (p=0.031). The distribution of NYHA-I patients for Q1, Q2, Q3 and Q4 were 40.7%, 22.8%, 23.8% and 12.7%, NYHA-II patients-30.8%, 23.1%, 27.2% and 18.9%, NYHA-III patients-21.2%, 23.9%, 24.3% and 30.6% and NYHA-IV patients-22.7%, 34.1%, 22.7% and 20.5%, respectively (p<0.001). Also, resting HR were found to gradually and significantly increase across NYHA categories (72.8±12 bpm in NYHA-I, 76.1±13 bpm in NYHA-II, 80.2±15 bpm in NYHA-III and 78.9±16 bpm in NYHA-IV, p<0.001). Conclusions: These results suggest that elevated resting HR in HF patients is associated with impaired HQoL and worse NYHA functional capacity.
