Active Interpersonal Touch Gives Rise to the Social Softness Illusion

Summary Social touch plays a powerful role in human life, with important physical and mental health benefits in development and adulthood. Touch is central in building the foundations of social interaction, attachment, and cognition [1-5], and early, social touch has unique, beneficial neurophysiological and epigenetic effects [6-9]. The recent discovery of a separate neurophysiological system for affectively laden touch in humans has further kindled scientific interest in the area [10, 11]. Remarkably, however, little is known about what motivates and sustains the human tendency to touch others in a pro-social manner. Given the importance of social touch, we hypothesized that active stroking elicits more sensory pleasure when touching others' skin than when touching one's own skin. In a set of six experiments (total N = 133) we found that healthy participants, mostly tested in pairs to account for any objective differences in skin softness, consistently judged another's skin as feeling softer and smoother than their own skin. We further found that this softness illusion appeared selectively when the touch activated a neurophysiological system for affective touch in the receiver. We conclude that this sensory illusion underlies a novel, bodily mechanism of socio-affective bonding and enhances our motivation to touch others

Emotion-Antecedent Appraisal Checks: EEG and EMG datasets for Goal Conduciveness, Control and Power

This document describes the full details of the second data set (Study 2) used in Coutinho et al., to appear. The Electroencephalography (EEG) and facial Electromyography (EMG) signals included in this data set, and now made public, were collected in the context of a previous study by Gentsch, Grandjean, and Scherer, 2013 that addressed three fundamental questions regarding the mechanisms underlying the appraisal process: Whether appraisal criteria are processed (1) in a fixed sequence, (2) independent of each other, and (3) by different neural structures or circuits. In this study, a gambling task was applied in which feedback stimuli manipulated simultaneously the information about goal conduciveness, control, and power appraisals. EEG was recorded during task performance, together with facial EMG, to measure, respectively, cognitive processing and efferent responses stemming from the appraisal manipulations

Novel Human Rotavirus Genotype G5P[7] from Child with Diarrhea, Cameroon

We report characterization of a genotype G5P[7] human rotavirus (HRV) from a child in Cameroon who had diarrhea. Sequencing of all 11 gene segments showed similarities to >5 genes each from porcine and human rotaviruses. This G5P[7] strain exemplifies the importance of heterologous animal rotaviruses in generating HRV genetic diversity through reassortment

G and P Genotyping of Human Rotavirus Isolated in a University Hospital in Korea: Implications for Nosocomial Infections

To characterize rotavirus G and P genotypes circulating among infants and young children hospitalized with severe diarrhea in a university hospital in Gyeonggi province, Korea, and to examine any association of the genotypes and nosocomial infections, we genotyped 103 isolates of rotavirus by multiplex RT-PCR. In July 2001-June 2002, we found that globally common strains constituted 64.2% (G2P[4] 28.3%, G3P[8] 28.3%, G4P[8] 5.7%, and G1P[8] 1.9%), and the uncommon strain, G4P[6], constituted 26.4%. During July 2002-June 2003, the percentage of common strains decreased to 44.0% (G3P[8] 18.0%, G2P[4] 16.8%, and G1P[8] 10.0%), but G4P[6] increased to 36.0%. G9P[8] was identified in 10.0% of cases, and thus can be considered an emerging strain in Korea. Eight-eight percent of G4P[6] was isolated from newborn babies. Among the 103 patients, there was an evidence of nosocomial rotavirus infection in 23 children (22.3%). Of these, 19 (82.6%) were newborns infected with G4P[6] strains of rotavirus. Most of the children who acquired rotavirus infection nosocomially showed symptoms of diarrhea, vomiting, fever, poor sucking, or dehydration, regardless of the genotype. This study revealed that G4P[6] has been the major genotype causing nosocomial rotavirus infection in our hospital

Isolation and characterization of a new simian rotavirus, YK-1

BACKGROUND: To effectively analyze the requirements for protection to rotavirus infection, a reliable animal model that reasonably mimics infection and disease in humans is needed. A requirement for an effective animal model is the availability of appropriate rotavirus stocks for challenge. RESULTS: A new simian rotavirus, designated YK-1, was isolated from a 2-year-old immunodeficient pigtailed macaque with chronic diarrhea. YK-1 was distinguishable by electropherotype from the other simian rotavirus strains, SA11 and RRV. One variant of YK-1, clone 311, which was isolated after adaptation and plaque purification in cell cultures, displayed an unusual RNA electropherotype with an abnormally migrating gene 11 segment. Sequence analysis demonstrated a genetic rearrangement that involved a partial duplication of the gene 11 ORF encoding NSP5. YK-1 was identified as a Group A rotavirus belonging to subgroup 1. To further characterize the YK-1 strain, the genes encoding VP4, VP7, and NSP4 were sequenced. Analysis of VP4 and VP7 gene fragments suggests that this strain is a G3P[3] rotavirus and is closely related to the simian rotavirus strain RRV. Serotype analysis also identified YK-1 as a G3 rotavirus. The NSP4 genotype of YK-1 is C, the same genotype as RRV. CONCLUSION: This newly isolated rotavirus, YK-1, is being used to establish a nonhuman primate model for studying the infectivity, immunity, and pathogenesis of rotavirus and for evaluating candidate rotavirus vaccines

Medical Oncology Professionals’ Perceptions of Telehealth Video Visits

IMPORTANCE: Telehealth has emerged as a means of improving access and reducing cost for medical oncology care; however, use by specialists prior to the coronavirus disease 2019 (COVID-19) pandemic still remained low. Medical oncology professionals’ perceptions of telehealth for cancer care are largely unknown, but are critical to telehealth utilization and expansion efforts. OBJECTIVE: To identify medical oncology health professionals’ perceptions of the barriers to and benefits of telehealth video visits. DESIGN, SETTING, AND PARTICIPANTS: This qualitative study used interviews conducted from October 30, 2019, to March 5, 2020, of medical oncology health professionals at the Thomas Jefferson University Hospital, an urban academic health system in the US with a cancer center. All medical oncology physicians, physicians assistants, and nurse practitioners at the hospital were eligible to participate. A combination of volunteer and convenience sampling was used, resulting in the participation of 29 medical oncology health professionals, including 20 physicians and 9 advanced practice professionals, in semistructured interviews. MAIN OUTCOMES AND MEASURES: Medical oncology health professionals’ perceptions of barriers to and benefits of telehealth video visits as experienced by patients receiving cancer treatment. RESULTS: Of the 29 participants, 15 (52%) were women and 22 (76%) were White, with a mean (SD) age of 48.5 (12.0) years. Respondents’ perceptions were organized using the 4 domains of the National Quality Forum framework: clinical effectiveness, patient experience, access to care, and financial impact. Respondents disagreed on the clinical effectiveness and potential limitations of the virtual physical examination, as well as on the financial impact on patients. Respondents also largely recognized the convenience and improved access to care enabled by telehealth for patients. However, many reported concern regarding the health professional–patient relationship and their limited ability to comfort patients in a virtual setting. CONCLUSIONS AND RELEVANCE: Medical oncology health professionals shared conflicting opinions regarding the barriers to and benefits of telehealth in regard to clinical effectiveness, patient experience, access to care, and financial impact. Understanding oncologists’ perceptions of telehealth elucidates potential barriers that need to be further investigated or improved for telehealth expansion and continued utilization; further research is ongoing to assess current perceptions of health professionals and patients given the rapid expansion of telehealth during the COVID-19 pandemic

The sense of agency as tracking control

Does sense of agency (SoA) arise merely from action-outcome associations, or does an additional real-time process track each step along the chain? Tracking control predicts that deviant intermediate steps between action and outcome should reduce SoA. In two experiments, participants learned mappings between two finger actions and two tones. In later test blocks, actions triggered a robot hand moving either the same or a different finger, and also triggered tones, which were congruent or incongruent with the mapping. The perceived delay between actions and tones gave a proxy measure for SoA. Action-tone binding was stronger for congruent than incongruent tones, but only when the robot movement was also congruent. Congruent tones also had reduced N amplitudes, but again only when the robot movement was congruent.We suggest that SoA partly depends on a real time tracking control mechanism, since deviant intermediate action of the robot reduced SoA over the tone

I had no other choice but to catch it too : the roles of family history and experiences with diabetes in illness representations.

BACKGROUND: A family history of diabetes and family members\u27 experiences with diabetes may influence individuals\u27 beliefs and expectations about their own diabetes. No qualitative studies have explored the relationship between family history and experiences and individuals\u27 diabetes illness representations. METHODS: Secondary data analysis of 89 exploratory, semi-structured interviews with adults with type 1 or type 2 diabetes seeking care in an urban health system. Participants had a recent diabetes-related ED visit/hospitalization or hemoglobin A1c \u3e 7.5%. Interviews were conducted until thematic saturation was achieved. Demographic data were collected via self-report and electronic medical record review. Interviews were audio-recorded, transcribed, and coded using a conventional content analysis approach. References to family history and family members\u27 experiences with diabetes were analyzed using selected domains of Leventhal\u27s Common Sense Model of Self-Regulation. RESULTS: Participants cited both genetic and behavioral family history as a major cause of their diabetes. Stories of relatives\u27 diabetes complications and death figured prominently in their discussion of consequences; however, participants felt controllability over diabetes through diet, physical activity, and other self-care behaviors. CONCLUSIONS: Findings supported an important role of family diabetes history and experience in development of diabetes illness representations. Further research is needed to expand our understanding of the relationships between these perceptions, self-management behaviors, and outcomes. Family practice providers, diabetes educators and other team members should consider expanding assessment of current family structure and support to also include an exploration of family history with diabetes, including which family members had diabetes, their self-care behaviors, and their outcomes, and how this history fits into the patient\u27s illness representations
