(要約)
The results of this study suggest that many pediatricians and OB/GYNs work long hours, and it is essential to improve their work environment, including task-shifting/task-sharing. Further enhanced recruitment and retention of hospital pediatricians and OB/GYNs is required. A detailed and large-scale study of pediatricians and OB/GYNs' working environments is essential in the future.

Among female students at the healthcare university, the HPV vaccination rate was thought to be comparatively low. Among those who had not received the HPV vaccine, it was particularly noted that they knew the term "HPV," were aware that HPV caused cervical cancer, and for those who had not undergone screenings, providing accurate information about "side effects" and " frightening" seemed necessary.

(要約)
Background Some literature reports an association between air temperature and mortality in certain diseases. However, the relationships between air temperature parameters and all causes of death have not been thoroughly explored in Japan. Objective This study examined the relationships between the number of deaths from the 10 leading causes and air temperature parameters in Hokkaido (the northernmost region) and Okinawa (the southernmost region) prefectures in Japan. Methods We collected monthly data on the number of deaths from the 10 leading causes and air temperature parameters in Hokkaido and Okinawa prefectures from January 2008 to December 2022 using information from official sources. Annual population data for each prefecture were also obtained. The relationships between the number of deaths and air temperature parameters were assessed through an ecological study. Results The mean air temperature was 9.59 ± 9.23 °C in Hokkaido and 23.46 ± 4.37 °C in Okinawa, with all temperature parameters significantly lower in Hokkaido than in Okinawa. The number of deaths from the 10 leading causes, excluding aspiration pneumonia, was significantly higher in Hokkaido for both sexes compared to Okinawa. In Hokkaido, deaths due to heart disease, cerebrovascular disease, pneumonia, accidents, and renal failure showed a significant correlation with all air temperature parameters for both sexes. In Okinawa, heart disease and cerebrovascular disease deaths were correlated with all air temperature parameters for both sexes. Conclusions The relationships between the number of deaths from the 10 leading causes and air temperature parameters differed between Hokkaido and Okinawa prefectures in Japan.

(要約)
Coronavirus infectious disease, that emerged in 2019 (COVID-19) has been a major public health issue not only in Japan, but also worldwide, and the implementation of a proper vaccination strategy has been important. To promote vaccination, the present study compared impressions of COVID-19 vaccinations stratified by the number of vaccinations among healthcare professional university students in Okayama, Japan, and suggests better vaccination strategies. A total of 212 Japanese healthcare professional university students were enrolled in this clinical qualitative study using the text mining method. A self-reported questionnaire, including questions such as "What do you think about COVID-19 vaccinations?" was performed. We also examined the number of vaccinations, sex, history of COVID-19 infection, and daily mask use. A total of 5,935 words were obtained and "Think" (169 times) was the most frequently used followed by "Inject" (108 times), "Inoculation" (97 times), "Vaccine" (83 times), "Corona" (66 times) and "Side effects" (49 times). Characteristic words were "Safety" in non-vaccinated subjects and "Side effects" and "Necessary" in vaccinated subjects. In addition, "Safety" in non-vaccinated men and "Frightening" in non-vaccinated women were characteristic and fundamental features. Impressions of COVID-19 vaccinations stratified by the number of vaccinations differed among healthcare professional university students. The provision of appropriate information on safety to non-vaccinated subjects and side effects to vaccinated subjects appears to be necessary. In addition, sex-specific information may be required for non-vaccinated subjects.

(要約)
The aim of this study was to compare impressions of COVID-19 vaccination and influenza vaccination in Japan by analyzing social media (Twitter) using a text-mining method. We obtained 10,000 tweets using the keywords "corona vaccine" and "influenza vaccine" on 15 December 2022 and 19 February 2023. We then counted the number of times the words were used and listed frequency of these words by a text-mining method called KH Coder. We also investigated concepts in the data using groups of words that often appeared together or groups of documents that contained the same words using multi-dimensional scaling (MDS). "Death" in relation to corona vaccine and "severe disease" for influenza vaccine were frequently used on 15 December 2022. The number of times the word "death" was used decreased, "after effect" was newly recognized for corona vaccine, and "severe disease" was not used in relation to influenza vaccine. Through this comprehensive analysis of social media data, we observed distinct variations in public perceptions of corona vaccination and influenza vaccination in Japan. These findings provide valuable insights for public health authorities and policymakers to better understand public sentiment and tailor their communication strategies accordingly.

(要約)
The present study investigated the pre-impressions of medical staff toward coronavirus disease 2019 (COVID-19) vaccination in a designated medical institution for class II infectious diseases in Sakaide, Japan using a text mining analysis. A total of 387 medical staff were surveyed on their pre-vaccination impressions toward the COVID-19 vaccine using an open-ended questionnaire from March 1st to 7th (the first survey) and from March 22nd to 28th (the second survey) at Sakaide City Hospital, Sakaide, Japan. A total of 296 people answered the question for the first time and 234 people answered for the second time among the 387 people. The vaccination rate was slightly lower for the younger generation than for the older generation. Before the first vaccination, the younger generation expressed concerns about side effects as well as a negative impact on pregnancy. However, before the second vaccination, there were fewer concerns regarding side effects and words of reassurance were also noted. Nurses expressed more opinions about side effects in both the first and second vaccinations than other medical staff. Concerns regarding side effects among medical staff decreased with the progression of COVID-19 vaccination. These data may provide useful information about the promotion of COVID-19 vaccination to the public, particularly in the young generation and women.

(要約)
The aim of this study was to investigate the pre-impressions of the third Coronavirus disease 2019 (COVID-19) vaccination among Japanese medical staff using quantitative analysis. Among 413 medical staff, 260 (60 men and 200 women) aged 40.4 ± 12.3 years were enrolled in this cross-sectional study. Pre-impressions of the third COVID-19 vaccination were analyzed using the text-mining analysis software, KH coder. Among 260 subjects, 242 (93.1%) agreed to the third vaccination, with the rate being lower among subjects in their 30s (87.3%) than those in the other age groups. The word "side effects" was characteristic of subjects in their 20s and nurses, and "pregnancy" of those in their 30s and administrative staff. Pre-impressions of the third COVID-19 vaccination varied among age groups and different professions. The results obtained provide useful information for promoting the third COVID-19 vaccination to Japanese adults.
