Mental health help-seeking preferences and behaviour in elite male rugby players.

Objectives: Mental health symptoms and mental illnesses are common in elite athletes. There is an urgent need to develop care systems to support the mental health of elite athletes. Understanding elite athletes' preferences in mental health help seeking can help explore strategies to develop such systems. Therefore, this study aims to investigate with whom/where elite athletes feel comfortable discussing mental health concerns and seeking help. Methods: We analyse data from 219 Japanese male rugby players out of 612 players (565 Japanese, 47 foreigners) aged 18 and over who belong to the Japan Rugby Players Association using a cross-sectional design and an anonymous, web-based, self-administered questionnaire. In the questionnaire, the players are asked to rate on a 5-point Likert scale how comfortable they feel talking about their mental health concerns with affiliation/team staff, family/relatives, friends, mental health professionals, rugby-related seniors and teammates. Analysis of variance and Dunnett's test are performed to detect differences in their preferences for sources of help. Results: Dunnett's test shows that the mean scores for preferring to consult affiliation/team staff are significantly lower than for all the other groups (p<0.001), indicating that players are reluctant to seek help for mental health concerns from affiliation/team staff. Fewer players sought help from affiliation/team staff or mental health professionals than from other groups. Conclusion: Regarding mental health concerns, for elite male rugby players as elite athletes, it can be difficult to ask for help or talk to team staff.

Optimal dose of brexpiprazole for augmentation therapy of antidepressant-refractory depression: A systematic review and dose-effect meta-analysis.

BACKGROUND: Brexpiprazole augmentation is an effective treatment strategy for antidepressant-refractory depression, but its optimal dosage remains unclear. AIMS: To find the optimal dosage of brexpiprazole as augmentation of other antidepressants. METHODS: We searched multiple electronic databases (from inception to September 16th, 2021) to identify double-blind, randomized placebo-controlled fixed-dose trials evaluating brexpiprazole augmentation therapy in adults (≥18 years old, both genders) with major depressive disorder not adequately responding to one or more antidepressant treatment. Our outcomes of interest at 8 weeks (range 4-12 weeks) were efficacy (treatment response defined as 50% or greater reduction in depression severity), tolerability (dropouts due to adverse effects) and acceptability (dropouts for any reason). We performed a random-effects, one-stage dose-effect meta-analysis with restricted cubic splines. RESULTS: Six studies met the inclusion criteria, including 1671 participants in total. The dose-efficacy curve showed an increase up to doses around 2 mg (odds ratio [OR] 1.52, 95% confidence interval [CI] 1.12-2.06) and then a decreasing trend through the higher licensed dose up to 3 mg (OR 1.40, 95% CI 0.95-2.08). The shape of the dose-tolerability curve was comparable to that of the efficacy and the dose-acceptability curve showed a monotonic increasing trend but both had wide confidence bands. CONCLUSIONS: One to two milligrams of brexpiprazole as augmentation treatment may achieve an optimal balance between efficacy, tolerability, and acceptability in the acute treatment of antidepressant-refractory depression. However, the small number of included studies limit the reliability of the results. Further research is required to validate the findings.

The presence and impact of estrogen metabolism on the biology of triple-negative breast cancer.

PURPOSE: While triple-negative breast cancer (TNBC) is negative for estrogen receptor alpha, a substantial proportion of carcinomas express estrogen receptor beta (ERß); consequently, estrogen actions and metabolism may be relevant in this cancer subtype. METHODS: A cohort of 81 TNBC patients from Tohoku University Hospital, Japan were characterised with regard to the expression of estrogen receptor beta and enzymes known to modulate levels of estrogens in breast and other tissues (Aromatase, 17-beta- Hydroxysteroid dehydrogenases 1, 2 and 6). This was done at the protein level by means of immunohistochemistry. As this cohort has been previously characterised for androgens, this also allows for comparison between the expressions of estrogen-related proteins and of androgen-related proteins. Preliminary mechanistic studies in cell culture were also undertaken. RESULTS: 17ßHSD2 was detected in the highest number of cases followed by 17ßHSD1, 17ßHSD6 and aromatase. When comparing the expression of ERß with that of the enzymes, it was positively correlated with the expression of 17ßHSD6 (p < 0.05) and trended towards correlation with dual expression of 17ßHSD1 and 2 (p < 0.07). 17ßHSD1 was associated with significantly reduced tumour volume (p = 0.0025), while ERß was associated with a trend towards reduced lymphovascular invasion, (p < 0.061). Interestingly, in survival analysis, 17ßHSD6 expression was the only one of these five factors that influenced survival, with positive samples being associated with longer disease-free survival compared to those that were negative for 17ßHSD6 (p < 0.05). In assessing associations with expression of proteins in the androgenic pathway, expression of aromatase appeared to be associated with androgenic pathways in TNBC patients (p < 0.05). Due to this association and the potential relevance to androgen-directed therapies in TNBC, we evaluated this interaction in vitro. We observed androgen-dependent upregulation of aromatase and ERß in a subset of AR expressing TNBC cell lines (MDA-MB-453, SUM-185-PE and MFM-223). CONCLUSION: Overall this study suggests the presence of, and a potential protective effect of estrogens in TNBC.
