The guidelines of brain death determination vary across countries. Our aim was to compare diagnostic procedures of brain death determination in adults among five countries. Consecutive comatose patients who received brain death determination from June 2018 to June 2020 were included. The technical specifications, completion rates and positive rates of brain death determination according to criteria of different countries were compared. The accuracy, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of each ancillary test for the identification of brain death diagnosed according to different criteria were investigated. One hundred and ninety nine patients were included in this study. One hundred and thirty one (65.8%) patients were diagnosed with brain death according to French criteria, 132 (66.3%) according to Chinese criteria, and 135 (67.7%) according to criteria of USA, UK and Germany. The sensitivity and PPV of electroencephalogram (92.2% – 92.3%) and somatosensory evoked potential (95.5% – 98.5%) were higher than transcranial Doppler (84.3% – 86.0%). The criteria of brain death in China and France are comparatively stricter than in USA, UK and Germany. The discrepancy in brain death determination between clinical assessments and additional confirmation of ancillary tests is small. [ABSTRACT FROM AUTHOR]

An online survey of 691 clinicians who use hypnosis was conducted in 31 countries to gain a broad real-world picture of current practices, views, and experiences in clinical hypnosis. Among 36 common clinical uses, stress reduction, wellbeing and self-esteem-enhancement, surgery preparations, anxiety interventions, mindfulness facilitation, and labor and childbirth applications were the most frequently rated as highly effective (each by ≥70% of raters) in the clinicians' own experience. Adverse hypnosis-associated effects had been encountered by 55% of clinicians but were generally short-lived and very rarely judged as serious. The most common hypnosis approaches used were Ericksonian (71%), hypnotic relaxation therapy (55%), and traditional hypnosis (50%). Almost all respondents reported regularly using other therapeutic modalities alongside hypnosis. Among a range of client variables potentially affecting therapy, most clinicians rated hypnotist-client rapport (88%) and client motivation (75%) as very or extremely important factors for successful hypnotherapy. The majority of respondents had conducted hypnosis treatment via teletherapy, and 54% of those estimated it to be as effective as in-person treatment. [ABSTRACT FROM AUTHOR]

We investigate the climatic influence on COVID-19 transmission risks in 228 cities globally across three climatic zones. The results, based on the application of a Boosted Regression Tree algorithm method, show that average temperature and average relative humidity explain significant variations in COVID-19 transmission across temperate and subtropical regions, whereas in the tropical region, the average diurnal temperature range and temperature seasonality significantly predict the infection outbreak. The number of positive cases showed a decrease sharply above an average temperature of 10°C in the cities of France, Turkey, the US, the UK, and Germany. Among the tropical countries, COVID-19 in Indian cities is most affected by mean diurnal temperature, and those in Brazil by temperature seasonality. The findings have implications on public health interventions, and contribute to the ongoing scientific and policy discourse on the complex interplay of climatic factors determining the risks of COVID-19 transmission.

People have a fair idea of how they are supposed to behave to slow down the spread of COVID-19. But what about people's perception of their own compared to others' adherence to the guidelines? Building on prior research on self-enhancement biases, we predicted that people perceive themselves to adhere more strictly to the COVID-19 guidelines than others. To test this hypothesis, we conducted a large-scale online experiment (N = 1,102), using a sample from four countries (UK, US, Germany, Sweden). As predicted, people perceived themselves to adhere to the COVID-19 guidelines more strictly than both the average citizen of their country and their close friends. These findings were robust across countries. Furthermore, findings were not moderated by whether people first thought about themselves or about others. In conclusion, our study provides a robust demonstration of how a long-standing psychological effect perseveres, even during a once-in-a-lifetime health crisis. [ABSTRACT FROM AUTHOR]

Research to date suggests older adults prefer a passive involvement in the clinical decision-making process; however, the empirical evidence underlying this claim in the mental health context is yet to be reviewed systematically. To understand whether older adults desire involvement in mental health-related clinical decisions. A systematic review was conducted to identify primary research that explored mental-health decision-making preferences of people with a mean age of over 55 from January 1990 through to December 2018. Three independent studies of varying design and quality were included. Study settings were in the USA, Germany, and the UK. A preference for shared decision-making was seen in two studies, while a preference for active decision-making was identified in one. In contrast to other reviews on clinical decision-making, this review focused on mental health-related decisions of older adults. The evidence suggests older adults desire involvement in mental health-related clinical decisions. Given the political drive to empower patients and the need to ensure evidence-based clinical practice, more high-quality research regarding the shared decision-making preferences and outcomes of older adults with mental ill-health is needed.
