Improvement of physical and mental health after transfemoral transcatheter aortic valve implantation

Transcatheter aortic valve implantation (TAVI) has emerged as a treatment alternative to surgical aortic valve replacement in elderly high-risk patients with symptomatic severe aortic stenosis. In this patient population, rapid improvement or restoration of quality of life (QoL) is at least as important as improved clinical outcomes. The purpose of the present study was to assess changes in QoL in response to TAVI.

[Physical and psychological status of 60-70-year-old citizens of Bern with neurotic symptoms in childhood--a study over more than 50 years (Emmental cohort)]

The present study was undertaken to assess the influence of childhood variables (physical and emotional) to later well-being in a group of rural Swiss (Emmental Cohort). Our study is the first prospective cohort over a time period of more than 50 years. It includes 1537 children who were listed and assessed in 1942 (T1) because they had difficulties in school or were otherwise behaviorally disturbed. In 1995 (T2) more than 60% of the initial population could be reassessed by our study group. We found more subjects at T2 who had been rated as intelligent at T1. More subjects responding to T2 belonged to a higher social class, were more anxious, and had more psychosocial problems at T1. Social income at T2 is correlated to the social class at T1. More subjects have died since who were rated at T1 as being less intelligent, less neurotical, and having higher psychosocial problems. Twice as many men died than women. The emotional situation at T2 is significantly correlated to psychological well-being at T1. The somatic complaints at T2 correlate significantly to neurotic symptoms in childhood (T1). The more intelligent the children were rated at T1, the less emotional and somatic complaints were voiced at T2 and the better the psychic well-being was rated (T2). In addition, the former social milieu (T1) significantly determined somatic and psychological complaints at T2. Our data discern a significant correlation between actual status and former childhood variables more than 50 years later in a rural Swiss cohort (Emmental Cohort).

Evaluation of physical and mental recovery status after elective liver resection

BACKGROUND AND OBJECTIVE: This prospective, clinical pilot trial compared the Short Form 36 Health Survey (SF-36) and a nine-item quality of recovery [Quality of Recovery 9 (QoR-9)] survey to assess the 1-week outcome after liver resection and prediction of postoperative complications from baseline values before liver resection. METHODS: In 19 patients, the SF-36 was recorded preoperatively (baseline) and on postoperative day (POD) 7. SF-36 z-values (means +/- SD) for the physical component summary (PCS) and mental component summary (MCS) were calculated. QoR-9 (score 0-18) was performed at baseline, POD1, POD3, POD5 and POD7. Descriptive analysis and effect sizes (d) were calculated. RESULTS: From baseline to POD7, PCS decreased from -0.38 +/- 1.30 to -2.10 +/- 0.76 (P = 0.002, d = -1.57) and MCS from -0.71 +/- 1.50 to -1.33 +/- 1.11 (P = 0.061, d = -0.46). QoR-9 was significantly lower at POD1, POD3 and POD5 compared with baseline (P < 0.050, d < -2.0), but not at POD7 (P = 0.060, d = -1.08). Baseline PCS was significantly lower with a high effect size in patients with complications (n = 12) compared with patients without complications (n = 7) (-0.76 +/- 1.46 vs. 0.27 +/- 0.56; P = 0.044, d = -0.84) but not baseline MCS (P = 0.831, d = -0.10) or baseline QoR-9 (P = 0.384, d = -0.44). CONCLUSIONS: The SF-36 indicates that liver resection surgery has a higher impact on physical health than on mental health. QoR-9 determines the feasible time course of recovery with a 1-week return to baseline. Preoperative impaired physical health might predict postoperative complications.

Perceptual and processing differences between physical and dichorhinic odor mixtures

Perceptual integration of sensory input from our two nostrils has received little attention in comparison to lateralized inputs for vision and hearing. Here, we investigated whether a binary odor mixture of eugenol and l-carvone (smells of cloves and caraway) would be perceived differently if presented as a mixture in one nostril (physical mixture), vs. the same two odorants in separate nostrils (dichorhinic mixture). In parallel, we investigated whether the different types of presentation resulted in differences in olfactory event-related potentials (OERP). Psychophysical ratings showed that the dichorhinic mixtures were perceived as more intense than the physical mixtures. A tendency for shift in perceived quality was also observed. In line with these perceptual changes, the OERP showed a shift in latencies and amplitudes for early (more "sensory") peaks P1 and N1 whereas no significant differences were observed for the later (more "cognitive") peak P2. The results altogether suggest that the peripheral level is a site of interaction between odorants. Both psychophysical ratings and, for the first time, electrophysiological measurements converge on this conclusion.

Mountain geography: physical and human dimensions

Mountains cover a quarter of the Earth's land surface and a quarter of the global population lives in or adjacent to these areas. This title gives students a foundation for understanding the geographical processes occurring in the world's mountains and the overall impact of these regions on culture and society as a whole.

Effects of physical and psychological stressors on adolescents’ cortisol levels and self-perceived stress in school

Both, psychosocial stress and exercise in the past have been used as stressors to elevate saliva cortisol and change state anxiety levels. In the present study, high-school students at the age of 14 were randomly assigned to three experimental groups: (1) an exercise group (n = 18), that was running 15 minutes at a medium intensity level of 65-75% HRmax, (2) a psychosocial stress group (n = 19), and (3) a control group (n = 18). The psychosocial stress was induced to the students by completing a standardized intelligence test under the assumption that their IQ scores would be made public in class. Results display that only psychosocial stress but not exercise was able to significantly increase cortisol levels but decreased cognitive state anxiety in adolescents. The psychosocial stress protocol applied here is proposed for use in future stress studies with children or adolescents in group settings, e.g., in school.
