Calculating the Social Return on Investment of a Japanese Professional Soccer Team's Corporate Social Responsibility Activities.

In response to the lack of evidence for visualizing the monetary value of professional sport teams' CSR-related social impact, this study aimed to calculate the social impact of a Japanese professional soccer team's corporate social responsibility (CSR) activity (i.e., community soccer/physical activity program) by using a social return on investment (SROI) framework. Specifically, Matsumoto Yamaga Football Club was used for the estimation. This professional soccer team was ranked in the top division of the league (J1) during the estimation period and engaged in CSR activities at 129 community soccer schools in a year (2019-2020). The SROI calculation involved five stages: (1) identifying key stakeholders, (2) mapping inputs, outputs, and outcomes, (3) measuring and valuing outcomes, (4) establishing impact, and (5) calculating SROI. For the first step, we specified seven major stakeholders (soccer team, nursery school children, parents, coaches, teachers, local governments, and local football associations) and conducted interview investigations with each stakeholder. Our result showed that the social value of the teams' targeted community soccer school was USD 54,160, and the total financial and non-financial inputs to the school were USD 10,134, meaning an SROI ratio of 5.3. This means that for every USD invested in a community soccer school, social benefit worth USD 5.3 was generated. This study contributes to advancing social impact research in sport by shedding light on the monetary value of the social impact of professional sport teams' CSR activities. In addition, it also has practical implications for team managers looking to utilize CSR activities as a management strategy, through cost-effective investment and optimization of resources.

[A case of posterior gastric arteriovenous malformation causing massive intraperitoneal hemorrhage].

We report abdominal bleeding caused by arteriovenous malformations (AVM) of the posterior gastric artery. A 38-year-old man visited our hospital complaining of epigastralgia. Enhanced abdominal CT revealed a high density spot in a huge low density mass. Angiographic study showed AVM of the posterior gastric artery. Transcatheter arterial embolization was performed and we successfully treated the AVM which was accompanied by abdominal bleeding.

[Huge unresectable multiple hepatic metastases of rectum cancer responding to combined therapy with FOLFIRI +bevacizumab - a case report].

We report a patient with a huge multiple hepatic metastases of rectal cancer treated by combination of infusional 5-FU, Leucovorin, irinotecan(FOLFIRI), and bevacizumab(BV). The patient was a 60-year-old man with cancer of the rectum, with huge multiple hepatic metastases. The serum carcinoembryonic antigen(CEA)level was 3,979.6 ng/mL, and the carbohy- drate antigen(CA)19-9 level was 66,562.6 U/mL. The patient received combined chemotherapy with FOLFIRI and BV. After completion of 8 courses, abdominal CT scans revealed that those low-density areas of the liver had reduced. The patient was judged to have achieved PR. He received combined therapy for 42 courses, and his response is SD at this point. No grade 2 adverse event occurred throughout chemotherapy. This case suggests that combined therapy with FOLFIRI+BV may be an effective regimen for advanced rectal cancer with huge multiple hepatic metastases.

Repair of incisional hernia with prolene hernia system.

A 70-year-old woman was admitted to our hospital with a complaint of bulging in the right lower portion of the abdomen. The bulging was in accordance with an old operative scar for appendicitis. The findings of computed tomography (CT) showed defects in the abdominal muscles and the protrusion of the intestine into the subcutaneous fat. The patient was diagnosed with incisional hernia after appendectomy and underwent a repair of the incisional hernia, using the prolene hernia system double-layer mesh. The patient's post-operative course was excellent. Recently, the prolene hernia system, double-layer mesh was reported to be effective for groin hernias due to its advantageous protection the recurrence through reinforcement of the patient's myopectrial orifice. It is suggested that this new device is also useful for small incisional hernias.
