Gratitude and Social Media: A Pilot Experiment on the Benefits of Exposure to Others' Grateful Interactions on Facebook.

Facebook and other social networking sites allow observation of others' interactions that in normal, offline life would simply be undetectable (e.g., a two-voice conversation viewable on the Facebook wall, from the perspective of a real, silent witness). Drawing on this specific property, the theory of social learning, and the most direct implications of emotional contagion, our pilot experiment (N = 49) aimed to test whether the exposure to others' grateful interactions on Facebook enhances (a) users' felt gratitude, (b) expressed gratitude, and (c) their subjective well-being. For the threefold purpose, we created ad hoc Facebook groups in which the exposure to some accomplices' exchange of grateful messages for 2 weeks was experimentally manipulated and users' felt/expressed gratitude and well-being were consequently assessed. Results partially supported both hypotheses. Observing others' exchange of grateful posts/comments on Facebook appeared to enhance participants' in-person expression of gratitude (i.e., self-reported gratitude expression within face-to-face interactions), but not their direct and subjective experiences of gratitude. Similarly, exposure to others' grateful messages improved some components of subjective well-being, such as satisfaction with life, but not negative and positive affect. Taken together, however, our preliminary findings suggest for the first time that social networking sites may actually amplify the spreading of gratitude and its benefits. Implications of our results for professionals and future research in the field of health, education, and social media communication are discussed.

Biosimilar epoetin alfa increases haemoglobin levels and brings cognitive and socio-relational benefits to elderly transfusion-dependent multiple myeloma patients: results from a pilot study.

Anaemia is a complication reported in up to 70% of the multiple myeloma patients (MM), with remarkable clinical, cognitive and socio-relational consequences. Anaemia relates to the course of MM, normalizing in patients during remission and reappearing in relapsing/non-responding patients. In a pilot study with 31 patients with MM and transfusion-dependent anaemia, we evaluated the effects of Binocrit (biosimilar epoetin alfa) on transfusions, haemoglobin levels, mental status (mini-mental state evaluation) and the patients' social-relational functioning and quality of life (QoL). Within a 12-week interval, patients received 40.000 U Binocrit once a week. Binocrit significantly decreased the incidence of transfusion, regardless of the patients' transfusion history, and significantly increased haemoglobin levels (before-and-after-treatment median haemoglobin values = 8.20 vs. 9.40 g/dl, respectively; Wilcoxon Z test, p < .001). A comparatively greater increment in haemoglobin levels among patients who responded to first vs. additional lines of chemotherapy was also observed. Importantly, we additionally found moderate-to-strong positive associations between increments in haemoglobin levels and corresponding increments both in psychological well-being and QoL (FACT-An scores) and the patients' cognitive status (mini-mental state evaluation scores). After statistically controlling for possible concurrent benefits of anti-myeloma therapy, increments in haemoglobin levels clearly predicted both increments in socio-relational FACT-An scores (Spearman's rho = 0.60, p < .001) and in cognitive functioning scores (Spearman's rho = 0.49, p < .006). Binocrit thus appears as an effective, well-tolerated agent for the management of myeloma anaemia, whose documented benefits include amelioration of anaemia, reduction in transfusion, and improvements in the patients' social-relational functioning and cognitive well-being.

Comparative clinical and psychosocial benefits of tooth bleaching: different light activation of a 38% peroxide gel in a preliminary case-control study.

Tooth bleaching is a widespread dental treatment with important psychosocial antecedents and outcomes involved. In the activation of in-office bleaching agents, a selective light radiation, that is, a diode laser seems to be a positive choice to decrease the time of bleaching without surface modification and with no residual tooth sensitivity for maximum effect and minimal clinical and psychological side effects.
