Strenuous exercise induces upper respiratory tract infection (URTI), whereas moderate exercise prevents URTI. This study aimed to assess the incidence of URTI and the association between URTI episodes and exercise duration in Japanese collegiate athletes. A cross-sectional survey was conducted with 1,740 participants; 1,235 responses were eligible for analysis. Participants were classified into three groups: control group (weekly total exercise duration <60 min, n=405), exercise group (weekly total exercise duration >60 min, n=193), and athlete group (joined a sports club and weekly exercise frequency >5 days, n=637). We requested the following information from participants: basic characteristics, incidence of URTI symptoms (fever, runny or plugged nose, sore throat, and cough) or influenza for each month over the past year, day of the week exercise is typically performed, and duration of exercise per week. The incidence of URTI episodes per year was significantly lower in the athlete group (2.0 ± 2.4 episodes) compared to the control group (2.6 ± 2.4 episodes, p<0.001). The incidence of URTI episodes did not significantly differ between the control group and exercise group (2.9 ± 2.9 episodes, p=0.607). Although the frequency of URTI episodes and exercise duration were not significantly associated among male athletes (p=0.209), they were positively associated in female athletes (p=0.027). These results indicate that Japanese collegiate athletes experience fewer URTI episodes than non-athletes, but athletes who exercise for long durations may frequently experience URTI, particularly female athletes.

Background: This study aimed to examine whether genotype categories of high-risk human papillomaviruses (HR-HPVs), when divided into HPV16/18, HPV 31/33/45/52/58, and HPV35/39/51/56/59/68, had an effect on the time required for and the proportion of cases that progressed to cervical intraepithelial neoplasia (CIN) grade 3 among women with CIN2.Patients: A total of 160 women aged 20–49 years and having CIN2 were recruited between January 2008 and June 2018. The time required for progression to CIN3 was determined by Kaplan-Meier time-to-event analysis. HPV genotypes were determined using the Linear Array HPV genotyping test.Results: During an average follow-up time of 22 months, 62 (39%) women with CIN2 progressed to CIN3, whereas 34 (21%) eliminated HR-HPVs and became cytologically normal. The majority (63%) of the women harboring HPV16/18 progressed to CIN3 with a 50% progression time of 11 months, whereas 26% of those harboring HPV31/33/45/52/58 progressed to CIN3 with a 50% progression time of 70 months.Conclusion: For every patient diagnosed with CIN2, genotyping to distinguish HPV16/18 from other HR-HPVs should be performed. Therefore, electing a surgical treatment, such as conization, should be considered as the primary option for women who are positive for HPV16/18, particularly when they are likely to be lost for follow-up or are 40 years old or older. In contrast, follow-up cytology should be repeated every 12 months for women harboring non-16/18 HR-HPVs. Those who tested negative for HR-HPV may be followed at the maximum interval of 24 months.

Objective: As coronavirus disease 2019 (COVID-19) rages on, it is a challenging task to balance resources for treatment of COVID-19 and malignancy-based treatment. For the development of optimal strategies, assessing the conditions and constrains in treatment during the COVID-19 pandemic is pertinent. This study reported about a nationwide survey conducted by the Japan Society of Gynecologic Oncology. Methods: We interviewed 265 designated training facilities about the state of their clinical practice from the time period between March and December 2020. We asked the facility doctors in charge to fill a web-based questionnaire. Results: A total of 232 facilities (87.5%) responded. A decrease in the number of outpatient visits was reported, and the major reason attributed was reluctance of patients to visit hospitals rather than facility restrictions. The actual number of surgeries decreased by 3.9%, compared to 2019. There was a significant difference when the variable of “Prefectures operating under special safety precautions” or not was introduced. There was no increase in the rate of advanced stages in the three cancer types studied. However, 34.1% participants perceived COVID-19 affected management and prognosis. Conclusion Refraining from visiting hospitals based on the patient's judgment may be expected to be an issue in the future. No significant decrease in surgeries was observed, and it would seem that there were few forced changes in treatment plans, but “the State of Emergency” had an impact. There was no increase in the rate of advanced cancers, but this will need to be monitored.
