It has been reported that diabetes mellitus is a significant risk factor for adverse outcomes after conventional CABG using cardiopulmonary bypass. However, the effects of diabetes on postoperative outcomes after off-pump coronary artery bypass grafting (OPCAB) are unclear. The effects of diabetes on early and mid-term results were studied by comparing the outcomes between 82 patients (65±5 years) with diabetes and 112 patients (68±11 years) without diabetes. The diabetic group included a greater preoperative presence of renal insufficiency (22.0% vs 8.9%, p=0.011) and history of cerebral vascular accident (25.6% vs 11.6%, p=0.012). Strategies, including graft choice, were not changed by presence of diabetes. The use of bilateral internal thoracic arteries (70.7% diabetes vs 67.0% nondiabetes), and frequency of total arterial bypass were similar in the 2 groups. The number of distal anastomoses was higher in the diabetic group (3.0±0.9 vs 2.7±0.9, p=0.042). The operation time and frequency of blood transfusion were similar in both groups. There was no hospital death in either group. Although mechanical ventilation time and postoperative ICU stay did not differ, hospital stay was significantly longer in the diabetic group (16.2 vs 13.3 days, p=0.0085). Postoperative major complications including atrial fibrillation were not significantly different between the 2 groups. Minor wound infection occurred in 2 patients, 1 in each group. There was no mediastinitis in either group. During the mean follow-up period of 20.8 months (1-39), there were two sudden deaths in the diabetic group, but no other cardiac death in either group. Cardiac event-free rate did not differ between the 2 groups. Although hospital stay in diabetic patients was longer than that in nondiabetic patients, early and mid-term results of OPCAB were not significantly affected by diabetes mellitus.

BACKGROUND: The Rugby World Cup (RWC) is one of the biggest international mega sports events in the world. This study was conducted to identify and evaluate the volume, nature, and severity of spectator medical care in the stadiums of 12 venues across Japan during RWC 2019. METHOD: This was a retrospective review of medical records from spectator medical rooms of 45 official matches of RWC 2019 between September 20 and November 2, 2019. All patients in the stadium who visited the spectator medical room and were transferred to a hospital were included. The wet bulb globe temperature (WBGT) value at the kick-off time of each match, the number of visits to the spectator medical room, and the number of transfers to a hospital were reviewed and analyzed. The patient presentation rate (PPR) was calculated per 10,000 attendees. Severity categories were defined as mild or severe. Mild cases were considered non-life threatening requiring minimal medical intervention, and severe cases required transport to a hospital. RESULT: The total number of visits to the spectator medical room was 449 with a PPR of 2.63. Most cases (91.5%) were mild in severity. The PPR was significantly higher for the matches held with a WBGT over 25 °C than for the matches under 21 °C (PPR 4.27 vs 2.04, p = 0.04). Thirty-eight cases were transferred to a hospital by ambulance; the PPR was 0.22. The most common reasons for transfer to the hospital were heat illness and fracture/dislocation, at a rate of 15.8% each. The incidence rate of cardiopulmonary arrest per 10,000 attendees was 0.0059 during RWC 2019. CONCLUSION Preparation and provision of appropriate medical service for spectators is a key factor for mass-gathering events. During RWC 2019, the majority (91.5%) of patients who sought medical attention did so for minor complaints, which were easily assessed and managed. On the other hand, a higher WBGT situation contributes significantly to an increased PPR (< 21 versus > 25, 2.04 versus 4.27, p = 0.04). Careful medical preparation, management, and development of public education programs for higher WBGT situations will be required in the future for similar international mega sports events.

Tohoku Medical and Pharmaceutical University, Japan, offers “Early Exposure to Medical Practice” in the first semester for first-year medical students to learn about patient-centered care as well as the real-world conditions and issues faced in community medical practice. Owing to the COVID-19 pandemic during the past two years, we planned and implemented online training, including some disability simulations, which mostly aimed to prevent the spread of infection. The students who completed these training courses reported that the online training had certain advantages over hands-on training ; the two activities implemented were not only effective in preventing infection but also had other benefits that only an online environment could provide. Herein, we report the results and some of the merits of these practices in 2021.
