Eating Disorder Awareness Campaigns:Thematic and Quantitative Analysis Using Twitter
Background: Health awareness initiatives are frequent but their efficacy is a matter of controversy. We have investigated the
effect of the Eating Disorder Awareness Week and Wake Up Weight Watchers campaigns on Twitter.
Objective: We aimed to examine whether the Eating Disorder Awareness Week and Wake Up Weight Watchers initiatives
increased the volume and dissemination of Twitter conversations related to eating disorders and investigate what content generates
the most interest on Twitter.
Methods: Over a period of 12 consecutive days in 2018, we collected tweets containing the hashtag #wakeupweightwatchers
and hashtags related to Eating Disorder Awareness Week (#eatingdisorderawarenessweek, #eatingdisorderawareness, or #EDAW),
with the hashtag #eatingdisorder as a control. The content of each tweet was rated as medical, testimony, help offer, awareness,
pro-ana, or anti-ana. We analyzed the number of retweets and favorites generated, as well as the potential reach and impact of
the hashtags and the characteristics of contributors.
Results: The number of #wakeupweightwatchers tweets was higher than that of Eating Disorder Awareness Week and
#eatingdisorder tweets (3900, 2056, and 1057, respectively). The content of tweets was significantly different between the hashtags
analyzed (P<.001). Medical content was lower in the awareness campaigns. Awareness and help offer content were lower in
#wakeupweightwatchers tweets. Retweet and favorite ratios were highest in #wakeupweightwatchers tweets. Eating Disorder
Awareness Week achieved the highest impact, and very influential contributors participated.
Conclusions: Both awareness campaigns effectively promoted tweeting about eating disorders. The majority of tweets did not
promote any specific preventive or help-seeking behaviors
Abnormal Distribution and Function of Circulating Monocytes and Enhanced Bacterial Translocation in Major Depressive Disorder
Introduction: Major depressive disorder (MDD) patients experience a systemic inflammatory stage. Monocytes play an important role in innate inflammatory responses and may be modulated by bacterial translocation. Our aim was to investigate the subset distribution and function of circulating monocytes, levels of proinflammatory cytokines, gut barrier damage, and bacterial translocation in MDD patients. Methods: Twenty-two MDD patients without concomitant diseases and 14 sex- and age-matched healthy controls were studied. The levels of circulating CD14++CD16- (classical), CD14++CD16++ (intermediate) and CD14- CD16++ (nonclassical) monocytes and the intracytoplasmic tumor necrosis factor (TNF)-α, interleukin (IL)-1ÎČ, IL-6, and IL-10 expression in the presence or absence of lipopolysaccharide (LPS) stimulation were analyzed by polychromatic flow cytometry. The serum TNF-α, IL-1ÎČ, IL-6, and IL-10 levels were measured by Luminex. LPS-binding protein (LBP), intestinal fatty acidbinding protein (I-FABP), and zonulin were measured by enzyme-linked immunosorbent assay (ELISA). Results: MDD patients had a significant increase in the frequency of intermediate monocytes and a significant decrease in the frequency of classical monocytes compared to those in the healthy controls. MDD patients had a significantly increased percentage of classical monocytes that expressed IL-1ÎČ, intermediate monocytes that expressed IL-1ÎČ and IL6 and nonclassical monocytes that expressed IL-1ÎČ, and decreased levels of nonclassical monocytes that expressed IL6 compared to those in the healthy controls. MDD patients had significantly increased levels of circulating TNF-α, IL-1ÎČ, LBP, and I-FABP compared to those in the healthy controls. MDD patients with high LBP levels had a significant reduction in the number of circulating monocytes compared to that in the normal-LBP MDD patients, which can be mainly ascribed to a decrease in the number of intermediate and nonclassical monocytes. Conclusions: We have demonstrated that compared to the healthy controls, MDD patients show a marked alteration in circulating monocytes, with an expansion of the intermediate subset with increased frequency of IL-1ÎČ and IL-6 producing cells. These patients also exhibited a systemic proinflammatory state, which was characterized by the enhanced serum TNF-α and IL-1ÎČ levels compared to those in the healthy controls. Furthermore, MDD patients showed increased LBP and I-FABP levels compared to those in healthy controls, indicating increased bacterial translocation and gut barrier damage
Exploring the extent of the hikikomori phenomenon on twitter: Mixed methods study of western language tweets
Background: Hikikomori is a severe form of social withdrawal, originally described in Japan but recently reported in other
countries. Debate exists as to what extent hikikomori is viewed as a problem outside of the Japanese context.
Objective: We aimed to explore perceptions about hikikomori outside Japan by analyzing Western language content from the
popular social media platform, Twitter.
Methods: We conducted a mixed methods analysis of all publicly available tweets using the hashtag #hikikomori between
February 1 and August 16, 2018, in 5 Western languages (Catalan, English, French, Italian, and Spanish). Tweets were first
classified as to whether they described hikikomori as a problem or a nonproblematic phenomenon. Tweets regarding hikikomori
as a problem were then subclassified in terms of the type of problem (medical, social, or anecdotal) they referred to, and we
marked if they referenced scientific publications or the presence of hikikomori in countries other than Japan. We also examined
measures of interest in content related to hikikomori, including retweets, likes, and associated hashtags.
Results: A total of 1042 tweets used #hikikomori, and 656 (62.3%) were included in the content analysis. Most of the included
tweets were written in English (44.20%) and Italian (34.16%), and a majority (56.70%) discussed hikikomori as a problem. Tweets
referencing scientific publications (3.96%) and hikikomori as present in countries other than Japan (13.57%) were less common.
Tweets mentioning hikikomori outside Japan were statistically more likely to be retweeted (P=.01) and liked (P=.01) than those
not mentioning it, whereas tweets with explicit scientific references were statistically more retweeted (P=.01) but not liked (P=.10)
than those without that reference. Retweet and like figures were not statistically significantly different among other categories
and subcategories. The most associated hashtags included references to Japan, mental health, and the youth.
Conclusions: Hikikomori is a repeated word in non-Japanese Western languages on Twitter, suggesting the presence of hikikomori
in countries outside Japan. Most tweets treat hikikomori as a problem, but the ways they post about it are highly heterogeneous

Areas of interest and stigmatic attitudes of the general public in five relevant medical conditions: Thematic and quantitative analysis using twitter
Background: Twitter is an indicator of real-world performance, thus, is an appropriate arena to assess the social consideration
and attitudes toward psychosis.
Objective: The aim of this study was to perform a mixed-methods study of the content and key metrics of tweets referring to
psychosis in comparison with tweets referring to control diseases (breast cancer, diabetes, Alzheimer, and human immunodeficiency
virus).
Methods: Each tweetâs content was rated as nonmedical (NM: testimonies, health care products, solidarity or awareness and
misuse) or medical (M: included a reference to the illnessâs diagnosis, treatment, prognosis, or prevention). NM tweets were
classified as positive or pejorative. We assessed the appropriateness of the medical content. The number of retweets generated
and the potential reach and impact of the hashtags analyzed was also investigated.
Results: We analyzed a total of 15,443 tweets: 8055 classified as NM and 7287 as M. Psychosis-related tweets (PRT) had a
significantly higher frequency of misuse 33.3% (212/636) vs 1.15% (853/7419; P<.001) and pejorative content 36.2% (231/636)
vs 11.33% (840/7419; P<.001). The medical content of the PRT showed the highest scientific appropriateness 100% (391/391)
vs 93.66% (6030/6439; P<.001) and had a higher frequency of content about disease prevention. The potential reach and impact
of the tweets related to psychosis were low, but they had a high retweet-to-tweet ratio.
Conclusions: We show a reduced number and a different pattern of contents in tweets about psychosis compared with control
diseases. PRT showed a predominance of nonmedical content with increased frequencies of misuse and pejorative tone. However,
the medical content of PRT showed high scientific appropriateness aimed toward prevention

Increasing interest of mass communication media and the general public in the distribution of tweets about mental diseases: observational study
Background: The contents of traditional communication media and new internet social media reflect the interests of society. However, certain barriers and a lack of attention towards mental disorders have been previously observed.
Objective: The objective of this study is to measure the relevance of influential American mainstream media outlets for the distribution of psychiatric information and the interest generated in these topics among their Twitter followers.
Methods: We investigated tweets generated about mental health conditions and diseases among 15 mainstream general communication media outlets in the United States of America between January 2007 and December 2016. Our study strategy focused on identifying several psychiatric terms of primary interest. The number of retweets generated from the selected tweets was also investigated. As a control, we examined tweets generated about the main causes of death in the United States of America, the main chronic neurological degenerative diseases, and HIV.
Results: In total, 13,119 tweets about mental health disorders sent by the American mainstream media outlets were analyzed. The results showed a heterogeneous distribution but preferential accumulation for a select number of conditions. Suicide and gender dysphoria accounted for half of the number of tweets sent. Variability in the number of tweets related to each control disease was also found (5998). The number of tweets sent regarding each different psychiatric or organic disease analyzed was significantly correlated with the number of retweets generated by followers (1,030,974 and 424,813 responses to mental health disorders and organic diseases, respectively). However, the probability of a tweet being retweeted differed significantly among the conditions and diseases analyzed. Furthermore, the retweeted to tweet ratio was significantly higher for psychiatric diseases than for the control diseases (odds ratio 1.11, CI 1.07-1.14; P < .001).
Conclusions: American mainstream media outlets and the general public demonstrate a preferential interest for psychiatric diseases on Twitter. The heterogeneous weights given by the media outlets analyzed to the different mental health disorders and conditions are reflected in the responses of Twitter followers

Being born in winter-apring and at around the time of an influenza pandemic are risk factors for the development of schizophrenia: The Apna Study in Navarre, Spain
Background: We analyzed the relationship between the prevalence of schizophrenia and the season of birth and gestation during a period of an influenza pandemic. Methods: Cross-sectional analysis of a prospective population-based cohort of 470,942 adults. We fitted multivariant logistic regression models to determine whether the season of birth and birth in an influenza-pandemic year (1957, 1968, 1977) was associated with schizophrenia. Results: 2077 subjects had been diagnosed with schizophrenia. Logistic regression identified a significantly greater prevalence of schizophrenia in men than in women (OR = 1.516, CI 95% = 1.388-1.665); in those born in the winter or spring than in those born in the summer or autumn (OR = 1.112, CI 95% = 1.020-1.212); and in those born in a period of an influenza pandemic (OR = 1.335, CI 95% = 1.199-1.486). The increase in risk was also significant when each influenza pandemic year was analyzed separately. However, neither month of birth nor season of birth, when each of the four were studied individually, were associated with a statistically significant increase in that risk. Conclusions: The winter-spring period and the influenza pandemics are independent risk factors for developing schizophrenia. This study contradicts many previous studies and thus revitalizes a locked debate in understanding the neurodevelopmental hypothesis of this disorder
