Are Patient Rights to Information and Self-Determination in Diagnostic Genetic Testing Upheld? A Comparison Of Patients’ and Providers’ Perceptions

This study assessed how the patient’s right to receive information and the right to self-determination were followed during diagnostic testing, according to the perceptions of patients and parents of tested children (group 1, n = 106) and healthcare personnel (group 2, n = 162). Data were collected in three Finnish university hospitals using a questionnaire. Results revealed one between group difference: patients/parents agreed more strongly than did personnel that self-determination was followed before testing. Within groups included: patients/parents had stronger agreement that self-determination was followed before testing than after testing; personnel had stronger agreement about information received after testing than before testing, and they had weaker agreement about how well self-determination was followed before testing than after testing. Received information was experienced as similar both before and after testing and by patients/parents and by personnel. Providing adequate time to consider whether or not to be tested and giving more support to patients after testing would promote the rights of patients. Furthermore, assessment of personnel characteristics is needed to determine, for example, the kinds of value conflicts that exist between personnel’s own values and patients’ values.     

Pain modulation during drives through cold and hot virtual environments.

Evidence exists that virtual worlds reduce pain perception by providing distraction. However, there is no experimental study to show that the type of world used in virtual reality (VR) distraction influences pain perception. Therefore, we investigated whether pain triggered by heat or cold stimuli is modulated by "warm "or "cold " virtual environments and whether virtual worlds reduce pain perception more than does static picture presentation. We expected that cold worlds would reduce pain perception from heat stimuli, while warm environments would reduce pain perception from cold stimuli. Additionally, both virtual worlds should reduce pain perception in general. Heat and cold pain stimuli thresholds were assessed outside VR in 48 volunteers in a balanced crossover design. Participants completed three 4-minute assessment periods: virtual "walks " through (1) a winter and (2) an autumn landscape and static exposure to (3) a neutral landscape. During each period, five heat stimuli or three cold stimuli were delivered via a thermode on the participant's arm, and affective and sensory pain perceptions were rated. Then the thermode was changed to the other arm, and the procedure was repeated with the opposite pain stimuli (heat or cold). We found that both warm and cold virtual environments reduced pain intensity and unpleasantness for heat and cold pain stimuli when compared to the control condition. Since participants wore a head-mounted display (HMD) in both the control condition and VR, we concluded that the distracting value of virtual environments is not explained solely by excluding perception of the real world. Although VR reduced pain unpleasantness, we found no difference in efficacy between the types of virtual world used for each pain stimulus.     

Emotional pictures predominate in binocular rivalry

This study used binocular rivalry to examine whether emotionally relevant pictures are processed preferentially in the visual system. Binocular rivalry occurs when two incompatible pictures are presented to both eyes. If the pictures cannot be merged to a single unambiguous percept, binocular rivalry results in an alternation of the two percepts. However, it has been controversial whether emotional picture content can influence a picture's relative predominance. Twenty pairs of emotional and neutral pictures from the International Affective Picture System (IAPS) were presented to 45 healthy participants. As hypothesised, emotional pictures significantly predominated over neutral pictures, both with respect to the first percept and the total viewing time across each trial. We conclude that the relative predominance of emotional pictures in binocular rivalry provides further support for the preferential processing of emotional stimuli in the visual system.     

Reappraising fear: is up-regulation more efficient than down-regulation?
