RESUMEN
Although there is ample literature available on toxicity in games, as there is regarding trolling on social media, there are few to no cross-platform studies on toxicity and trolling. In other words, the extant literature focuses on one platform at a time instead of comparing and contrasting them. The present work aims to rectify this gap by analyzing interviews from a larger study of 22 self-proclaimed victims of in-game trolling to not only determine whether social media or gaming communities are considered more toxic but also to explore how definitions of the word 'trolling' change depending on the platform in question. We found that while definitions of in-game trolling behavior focused on behavioral styles of trolling (e.g., throwing one's avatar into enemy fire to disadvantage one's team, and blocking other players' avatars' movement), social media trolling is defined by more sinister actions such as misinformation spreading and 'canceling' other users. We also found that gaming is perceived as generally more toxic than social media, often due to company policies or lack thereof. Practical and theoretical implications for the study of toxicity in all online communities - gaming or social-media based - are discussed.
RESUMEN
Live streaming is a unique form of media that creates a direct line of interaction between streamers and viewers. While previous research has explored the social motivations of those who stream and watch streams in the gaming community, there is a lack of research that investigates intimate self-disclosure in this context, such as discussing sensitive topics like mental health on platforms such as Twitch.tv. This study aims to explore discussions about mental health in gaming live streams to better understand how people perceive discussions of mental health in this new media context. The context of live streaming is particularly interesting as it facilitates social interactions that are masspersonal in nature: the streamer broadcasts to a larger, mostly unknown audience, but can also interact in a personal way with viewers. In this study, we interviewed Twitch viewers about the streamers they view, how and to what extent they discuss mental health on their channels in relation to gaming, how other viewers reacted to these discussions, and what they think about live streams, gaming-focused or otherwise, as a medium for mental health discussions. Through these interviews, our team was able to establish a baseline of user perception of mental health in gaming communities on Twitch that extends our understanding of how social media and live streaming can be used for mental health conversations. Our first research question unraveled that mental health discussions happen in a variety of ways on Twitch, including during gaming streams, Just Chatting talks, and through the stream chat. Our second research question showed that streamers handle mental health conversations on their channels in a variety of ways. These depend on how they have built their channel, which subsequently impacts how viewers perceive mental health. Lastly, we learned that viewers' reactions to mental health discussions depend on their motivations for watching the stream such as learning about the game, being entertained, and more. We found that more discussions about mental health on Twitch led to some viewers being more cautious when talking about mental health to show understanding.
RESUMEN
This study investigated whether sexually transmitted infections and lifestyle variables are associated with premenstrual syndrome (PMS) as well as particular manifestations commonly associated with PMS. Data were gathered from medical records of 500 regularly cycling women. The following infectious agents were investigated: human papillomavirus, Chlamydia trachomatis, Neisseria gonorrheae, Gardnerella vaginalis, Candida albicans, and Trichomonas vaginalis. Bivariate tests and multivariate logistic regressions were used to evaluate whether these pathogens were associated with headache, pain, nausea, and depression. Chlamydia trachomatis was significantly associated with premenstrual syndrome (PMS) and two common manifestations of PMS: depression and pain. Trichomonas vaginalis was significantly correlated with headache and Gardnerella vaginalis with nausea. None of the illness manifestations was significantly associated with the tested lifestyle variables: dietary calcium supplementation, alcohol and drug use, exercise, and smoking. These associations provide a basis for assessment of infectious causation of PMS and several manifestations of illness that are commonly associated with PMS.

Amyloid-beta peptide (Abeta) plays an essential pathophysiologic role in Alzheimer disease, and elevation of luteinizing hormone (LH) levels during aging has been implicated in its pathogenesis. To assess the effect of LH receptor deficiency on Abeta accumulation, we generated a bigenic mouse model, APPsw(+)/Lhr(-/-), which expresses human amyloid precursor protein (APPsw) in the background of LH receptor (Lhr) knockout. Genetic ablation of Lhr resulted in a significant decrease in the number of Abeta plaques and protein content in the hippocampus and cerebral cortex in both male and female mice. Accordingly, several Abeta deposition-related neuropathologic features and functionally relevant molecules were markedly improved, including decreased astrogliosis, reductions of elevated phosphorylated tau, c-fos, alpha7-nicotinic acetylcholine receptor, and restoration of the altered neuropeptide Y receptors Y1 and Y2. Diminution of Abeta accumulation in the absence of LH receptor supports the contention that dysregulation of LH may impact the pathogenesis of Alzheimer disease. The APPsw(+)/Lhr(-/-) mouse may be a useful tool for advancing understanding of the role of LH-mediated events in Alzheimer disease and a model in which to test therapeutic interventions.

OBJECTIVE: To examine the relationship of serum müllerian-inhibiting substance (MIS), E(2), free-T, LH, and FSH in untreated women with polycystic ovary syndrome (PCOS) and in women with normal menstrual cycles. DESIGN: A prospective study. SETTING: University Departments of Obstetrics and Gynecology and Surgery. PATIENT(S): Twenty-seven women with PCOS and 20 women with normal menstrual cycles. INTERVENTION(S): Serum was collected from women with PCOS and from normal women during the early follicular phase of the menstrual cycle, stored frozen until assayed. MAIN OUTCOME MEASURE(S): Serum levels of MIS, E(2), free-T, TSH, LH, and FSH were measured. RESULT(S): Serum müllerian-inhibiting substance levels in PCOS patients were significantly higher compared with normal women (+/- SE; 5.3 +/- 0.7 and 1.4 +/- 0.2 ng/mL, respectively). An inverse correlation (r = -0.5965) was found between serum levels of MIS and E(2) in PCOS women, but not in normal women. Women with PCOS had higher serum LH levels than those of normal women (15.2 +/- 1.2 and 5.0 +/- 0.7 mIU/mL). CONCLUSION: In this study, women with PCOS have significantly higher serum MIS levels than normal women. The inverse relationship between müllerian-inhibiting substance and E(2) levels suggests that MIS may modulate ovarian E(2) synthesis and have a role in the disordered folliculogenesis characteristic of PCOS.
