Title Alternative Experience with a nosocomial cluster of novel coronavirus infection and the cluster response algorithm
Author Fujita, Koji| Ocho, Kazuki| Kadowaki, Tomoka| Yorifuji, Takashi| Otsuka, Fumio|
Abstract  The novel coronavirus disease (COVID-19) pandemic that began in 2019 is yet to end, as of the summer of 2022. During the pandemic, community-acquired infections spread easily to healthcare-associated facilities, resulting in COVID-19 clusters among high-risk individuals that have been difficult to contain. Our regional base hospital also experienced a nosocomial cluster of COVID-19 in October 2020 that took 30 days to contain and affected 9 hospital staff and 14 patients. Six patients died due to COVID-19, and six died due to COVID-19-related complications. Two patients were discharged alive. Patient characteristics included ① advanced age (79.0±8.1 years), ② dementia (64.3%), ③ low Prognostic Nutrition Index (31.1 ±7.9), ④ zinc deficiency (50.2±13.1μg/dL), ⑤ vitamin C deficiency (1.6±1.9μg/mL), ⑥ elevated urea nitrogen-to-creatinine ratio (27.4±23.5), ⑦ anticancer and immunosuppressive drug use (78.6%), and ⑧ malignancy (75.6%). This cluster had a very high mortality rate, but the viral spread was contained in a short period. Algorithmizing the cluster response was crucial to controlling this cluster. We report on our actual cluster response algorithm, as well as our strategy and response procedure during the pandemic.

Title Alternative A descriptive analysis for the comparison of the symptoms and severity of coronavirus disease 2019 (COVID-19) in each epidemic period in Okayama City
Author Matsuo, Rumi| Matsumoto, Naomi| Kadowaki, Tomoka| Mitsuhashi, Toshiharu| Takao, Soshi| Yorifuji, Takashi|
Abstract  Japan experienced four major epidemic periods (i.e., the 3rd-6th waves) of COVID-19 from January 2020 to March 2022. A different strain predominated in each period: the wild-type strain, an Alpha variant, a Delta variant, and an Omicron variant were predominant in waves 3, 4, 5, and 6, respectively. In this study, we conducted a descriptive analysis to investigate the differences in symptoms and severity during each epidemic period. We analyzed a total of 31,037 patients with COVID-19 who were reported to the Okayama City Public Health Center between February 1, 2020 and March 31, 2022. We described and compared the proportion of symptoms, the number and proportion of severe COVID-19 cases, and the number and proportion of deaths for each epidemic period. We also compared the proportion of severe COVID-19 cases depending on the number of vaccinations for the 5th and 6th waves.
 Differences in symptoms and severity were observed in each epidemic period. In the 5th and 6th waves, the results suggested that vaccination had a preventive effect against severe COVID-19.

Title Alternative Clusters of coronavirus disease 2019 in medical institutions and elderly care facilities in Okayama Prefecture
FullText URL 134_86.pdf

Abstract  Coronavirus disease 2019 has spread worldwide and has yet to be contained. The Japanese government has taken measures against the occurrence of clusters. However, there has little evaluation of the occurrence of the clusters and their changes. Therefore, we investigated the occurrence of the clusters in medical institutions and elderly care facilities in Okayama Prefecture.
 We compared the characteristics of the clusters that occurred in each of the wave between October 21, 2020, and September 30, 2021, by using the data published that interval. As a case study, we also evaluated the characteristics of positive patients at a medical institution over where a cluster occurred in case the fourth wave.
 The overall number of cluster outbreaks decreased with the spread of vaccination. In the fourth wave, there was a period in which the vaccination of staff members at medical institutions became widespread, while patients or facility users were unvaccinated, resulting in a longer convergence period and an increase in the number of positive cases among patients relative to the number of staff members.
 The impact of the spread of vaccination and the duration of immunity acquired after vaccination on the occurrence of clusters should be closely monitored in the future.

Abstract Psychosomatic disorders are influenced by psychosocial factors such as interpersonal relationships. Coping behaviors, especially in frustrating situations, reflect a patient’s ability to cope with stress, and it is important to assess these behaviors for the treatment of psychosomatic diseases. This study aimed to clarify the interpersonal relationships and coping behaviors of pediatric patients with psychosomatic diseases during frustrating situations simulated using the Rosenzweig Picture-Frustration study. This retrospective study included 126 patients (41 male, 85 female) with an average age of 12.9 (6-16) years who were consulted at the Department of Pediatric Psychosomatic Medicine at Okayama University Hospital from 2013 to 2018 and underwent the P-F study. Each score was compared with a standardization sample. The mean group conformity rating did not differ significantly between the participants and healthy children. Compared with healthy children, those with psychosomatic diseases were less likely to explain their perspective. The children with psychosomatic disorders responded to frustrating situations in a sensible and age-appropriate manner. However, they were less likely to respond by explaining their perspective to protect themselves.
