To understand who uses social media and how often they do so, we examined the personality traits that predict frequency of using a set of 10 different types of social media (e.g., social networks, blogs, virtual worlds). Using survey data collected from two large-scale samples of young adults (Exploratory Study 1 N = 1586, Confirmatory Study 2 N =1432), we conducted direct replications of our findings to test whether the observed relationships between social media use and personality traits were reliable. Our replicated findings reveal that sex, age and extraversion are reliable predictors of several types of social media use (e.g., Facebook, Messaging Platforms, Online Forums), while other traits (e.g., agreeableness, Machiavellianism) showed unreliable associations. Our findings also reveal dimensions of multiplatform social media use that categorize the media ecologies of young adults and show significant associations with individual difference measures.

Therapeutic plasma exchange (TPE) is used to treat more than 60 diseases worldwide and has drawn growing interest. Little is known about the current situation of TPE activity in Turkey, so we developed a survey to obtain information about this timely topic. We collected data on TPE from 28 apheresis units throughout Turkey. We performed a total of 24,912 TPE procedures with 3203 patients over the past decade. Twenty years ago, the majority of procedures were performed for neurological and hematological disorders, and today, most TPE procedures are done for the same reasons. The only historical change has been an increase in TPE procedures in renal conditions. Currently, renal conditions were more frequently an indication for TPE than rheumatic conditions. Fresh frozen plasma was the most frequently used replacement fluid, followed by 5% albumin, used in 57.9% and 34.6% of procedures, respectively. The most frequently used anticoagulants in TPE were ACD-A and heparin/ACD-A, used with 1671 (52.2%) and 1164 (36.4%) patients, respectively. The frequency of adverse events (AEs) was 12.6%. The most common AEs were hypocalcemia-related symptoms, hypotension, and urticaria. We encountered no severe AEs that led to severe morbidity and mortality. Overall, more than two thirds of the patients showed improvement in the underlying disease. Here, we report on a nationwide survey on TPE activity in Turkey. We conclude that there has been a great increase in apheresis science, and the number of TPE procedures conducted in Turkey has increased steadily over time. Finally, we would like to point out that our past experiences and published international guidelines were the most important tools in gaining expertise regarding TPE.
