In 2009, the Japan Anti-Doping Agency (JADA) established the “Sports Pharmacist Accreditation Program” to prevent doping in sports. Since then, anti-doping activities in Japan have been attracting attention. In this study, we investigated research about the current status of doping from 2007 to 2014 in Japan to make anti-doping activities more concrete, and we also discussed future anti-doping activities by pharmacists. In Japan, bodybuilding was the sporting event with the highest number and rate of doping from 2007 to 2014. Many of the positive doping cases were detected for class S1 (anabolic agents), S5 (diuretics and masking agents), and S6 (stimulants). Within class S1, supplements were the main cause of positive doping. Within class S5, medicines prescribed by medical doctors were the main cause of positive doping. Within class S6, non-prescription medicines (e.g., OTC) were the main cause of positive doping. When we looked at the global statistics on doping, many of the positive doping cases were detected for class S1. On comparing the Japanese statistics with the global statistics, the rate of positive doping caused by class S1 was significantly lower, but that caused by classes S5 and S6 was significantly higher in Japan than in the world. In conclusion, pharmacists in Japan should pay attention to class S1, S5, and S6 prohibited substances and to the sport events of bodybuilding. Based on this study, sports pharmacists as well as common pharmacists should suggest new anti-doping activities to prevent doping in the future.

The spread of Video on Demand (VOD) services is driving the creation of video viewing environments in which users can watch whatever they like, whenever they like. The recent appearance of social networking services (SNSs), moreover, is bringing big changes to the world of media by enabling anyone to become a disseminator of information. We are studying a platform that combines VOD and SNS to create ``horizontal links'' between program viewers, and to facilitate encounters with new programs. To investigate user behaviors on this platform, we built an SNS site called ``teleda,'' that enables program viewing by VOD, and conducted a large-scale, three-month verification trial with about 1000 participants. In this paper, we report on the relational analysis of teleda users' viewing and communication behaviors. In order to clarify how the users' communication structures relate to the viewing and posting behaviors on this system, we described the communication structures in terms of network structures, and ran a correlation analysis of network indicators and user behavior indicators such as viewing and posting. As a result, we revealed that relationships between the users' communication structures, viewing behaviors, and posting actions are characteristics of each program's genre.

Background:Cell therapy is a therapeutic option for patients presenting with nonrevascularizable critical limb ischemia (CLI). However there is a lack of firm evidence on its efficacy because of the paucity of randomized controlled trials.Methods and Results:The BALI trial was a multicenter, randomized, controlled, double-blind clinical trial that included 38 patients. For all of them, 500 mL of bone marrow were collected for preparation of a BM-MNC product that was implanted in patients assigned to active treatment. For the placebo group, a placebo cell-free product was implanted. Within 6 months after inclusion, major amputations had to be performed in 5 of the 19 placebo-treated patients and in 3 of the 17 BM-MNC-treated patients. According to a classical logistic regression analysis there was no significant difference. However, when using the jackknife analysis, 6 months after inclusion BM-MNC implantation was associated with a lower risk of major amputation (odds ratio (OR): 0.55; 95% confidence interval (CI): 0.52–0.58; P<0.0001) and of occurrence of any event (major or minor amputation, or revascularization) (OR: 0.30; 95% CI: 0.29–0.31; P<0.0001). The secondary endpoints (i.e., pain, ulcers, TcPO2, and ankle-brachial index value) were not statistically different between groups.Conclusions:Our results suggested that cell therapy reduced the risk of major amputation in patients presenting with nonrevascularizable CLI.

【背景】手術技術の向上と内科管理の進歩によりFontan型手術の生存率は飛躍的に向上したが、Fontan手術適応ぎりぎりの症例に直面することも少なくない。またfenestrationを設けるべきかどうかの基準も一定の見解が無いのが現状である。【目的】Fontan手術の適応限界やfenestrationを設ける基準について検討すること。【方法】2010年1月~2013年12月までの4年間に当院でTCPCを行った128例を対象とした(IVC欠損例は除外した)。手術時年齢の中央値は2.5歳(1.0~37.0歳)。nonfenestrated TCPC手術(n-TCPC)を行った症例をN群(n=82, 64%)、fenestrated TCPC手術(f-TCPC)を行った症例をF群(n=46, 36%)とした。【結果】 病院死亡は2例(1.6%)、遠隔死亡は1例(0.8%)ですべてF群であった。術前カテデータでは、F群の方がN群よりSaO2が低く(83±5% vs 86±4%)、PAIも低かった(219±117 vs 291±129)。術後入院期間は、F群の方がN群より長かった(44±81日 vs 25±16日)が、術後ドレーン留置期間に差はなかった。術後カテデータでは、F群の方がN群より主心室の拡張末期圧が高く(9.2±3.4 vs 7.0±2.6)、肺動静脈間圧較差が小さく(4.5±1.4 vs 5.5±1.9)、SaO2が低かった(87±35 vs 94±2)。Qsに差はなかった。F群の3例(6.5%)、N群の2例(2.4%)でPLEを発症した。【考察】F群で死亡例やPLE発症例を多く認め、術後入院期間も長かったのは、術前条件が不良でFontan手術の厳しい症例が多かったことによる。術前のSaO2の低い、PAIの低い症例は、肺血管床の発育が不十分でありfenestrationを設けるべきである。しかし、fenestrationを設けた場合には術後主心室の拡張末期圧が高くなる可能性がある。【結論】肺血管床の乏しい症例はfenestrationを設けた方が良いが、心機能の悪い症例はfenestrationは無い方が良い。肺血管床が乏しく心機能も不良な症例のFontan手術適応は慎重に判断すべきである。

The purpose of this study was to develop pilot evaluation of psychometric property of the Coach-Athlete Relationship Maintenance Questionnaire (CARM-Q) in Japanese junior tennis players and to examine its reliability and validity. The athlete version of CARM-Q was administered to 240 Japanese junior tennis players with a mean age of 15.7±1.3 years. Results of a confirmatory factor analysis replicated the factor structure found in the original version of the CARM-Q (Rhind and Jowett, 2012). Furthermore, it was suggested that the athlete version of CARM-Q had sufficient reliability and validity. The effects of the combination pattern of the coach-athlete dyad (athlete male/coach male, athlete male/coach female, athlete female/coach male, and athlete female/coach female) were tested via MANOVA using 7 subscales from the CARM-Q. Results revealed that the athlete male/coach female group was higher in Conflict management, Openness, and Motivational than the athlete male/coach male group. Additionally, the athlete female/coach male group revealed higher Motivational than the athlete male/coach male group. Future applications were also discussed regarding the CARM-Q as an assessment of the quality of the coach-athlete relationship in Japanese junior sport settings.

Composer Frederic (Federico) Mompou (1893-1987) searched throughout his life for ways to express his own musical ideals and sensibilities. This paper examines his attitude toward this search, and also analyzes changes in his means of musical expression as shown in his songs. From 1914 to 1915, Mompou was greatly concerned with the problem of finding his own means of musical expression. He wrote a report entitled "Estudi del sentiment per a l'interpretacio al piano," in which he reconsidered and reanalyzed traditional musical terms. From this, we can see that his search for his own musical language began while he was still young; this search continued throughout Mompou's career, not only in his piano works, but also in his vocal works. In order to analyze the changes in musical language in Mompou's vocal works, the following songs were selected: L'hora grisa (1915) from his early period; Cortina de fullatge (1925) and Canconeta incerta (1926) from his middle period; Damunt de tu nemes les flors and Aquesta nit un mateix vent (from the suite Combat del Somni; 1942-51) for his mature period; and finally La fausse morte (from the suite Cine chansons sur les poemes de Paul Valery; 1973) for his later years. Through this analysis the following characteristics have been shown: In his early and middle periods: (1) Mompou avoided conventional stability by using an "ambiguous tonality" which although diatonic is neither major nor minor (even when a mode is used, cadences do not have traditional chords); (2) he tended to avoid definiteness through using parallel dominant chord progressions; (3) he used the major second interval as a standard device to express anguish or pain in the song text. In his middle and mature periods, in addition to the above techniques: (4) Mompou used "two-storied chords" (an invented term meaning a kind of compound chord made from two adjoining chords) with increasing frequency and effectiveness; (5) his work came to show a characteristic sense of cadence through the use of 3rd inversion chords. All of these characteristics give a particular color to Mompou's songs, distinguishing him from other Spanish composers in the 20th century. In his later years, Mompou adopted Messiaen's "2nd mode" in his vocal work La fausse morte. But this fact is closely related to his use of parallel dominant chord progressions in his earlier works. Mompou's adoption of this mode for his own expressive purposes should be seen to reflect his interest in the use of diminished chords for their dominant function, and the fact that the combination of tones in Messiaen's 2nd mode give a richness in melody which satisfied Mompou's sense of sound in his later years.
