The objectives of the present study were to evaluate the anatomic localization of porcine reproductive and respiratory syndrome virus (PRRSV) in naturally infected pigs and to determine whether oral fluid could be used to detect the virus in infected animals. Two sows, seven 2-month-old grower pigs, and 70 6-month-old gilts were included in this study. PRRSV in sera and oral fluid were identified by nested reverse transcription PCR (nRT-PCR) while lung, tonsil, and tissue associated with oral cavity were subjected to nRT-PCR, immunohistochemistry, and in situ hybridization. In sows, PRRSV was identified in oral fluid and tonsils. PRRSV was also detected in oral fluid, tonsils, salivary glands, oral mucosa, and lungs of all seven grower pigs. However, viremia was observed in only two grower pigs. Double staining revealed that PRRSV was distributed in macrophages within and adjacent to the tonsillar crypt epithelium. In gilts, the North American type PRRSV field strain was detected 3 to 8 weeks after introducing these animals onto the farm. These results confirm previous findings that PRRSV primarily replicates in tonsils and is then shed into oral fluid. Therefore, oral fluid sampling may be effective for the surveillance of PRRSV in breeding herds.

We conducted a questionnaire survey of 525 persons regarding end-of-life care (EoLC) between November and December 2017. A total of 495 individuals responded (response rate 94.3%). Respondents were grouped into either a medical staff (MS) group or community persons (CP) group. Significant differences were found between the MS and CP groups in implementing a family conference about EoLC (p<0.05), but not in preparing documents about personal preferences for EoLC. There were significant differences between the groups in medical treatments in EoLC, for example, total parenteral nutrition, enteral nutrition via percutaneous endoscopic gastrostomy, and mechanical ventilation with intubation (p<0.05). It is important that medical treatment in EoLC should meet the requirements of patients and their families. This study revealed differences in some aspects of EoLC between the MS and CP groups. Individuals should be supported in personally making decisions about their own EoLC.

The purpose of this study was to clarify difficulties and countermeasures in nursing practice for foreign patients with COVID-19 who were non-English native speakers. A questionnaire was collected from 16 nurses in a COVID-19 ward. They cared for 13 non-English-speaking foreign patients from admission to discharge in the ward between May 2021 and June 2021. All nurses reported difficulties in communication related to collecting information from patients and explaining hospital care. For example, they could have simple conversations using a two-way translation device (POKETALK®) but could not understand detailed symptoms or complaints without an interpreter. Not much meaning could be inferred from a patient’s response of “OK”. The nurses reported that it was difficult to explain details of treatments, Japanese customs, and hospital rules. With the help of interpreters, they made hospital manuals and question cards in the patients’ native languages. In nursing care for foreign patients with COVID-19, it was helpful to provide explanations of Japanese customs and hospital rules before admission and to prepare hospital manuals and question cards in patients’ native languages.

A woman in her 80s was being treated for dementia. She lived in a four-generation household of 8 people. Her grandchild contracted COVID-19 and was admitted in another hospital. The 7 other family members were close contacts of the grandchild, and all of them except the woman with dementia developed COVID-19 within 3 days of onset in the grandchild. The woman’s PCR test for SARS-CoV-2 was negative. Her family thought that she could not live alone, but she was denied admission to other hospitals. Finally, she was admitted to our COVID-19 ward with her other family members at the family's request. After admission, she stayed in a room with family members, and COVID-19 treatment for her family and her care were performed with strict infection control measures in place. On hospital day 11, she and 5 family members had negative PCR test results for SARS-COV-2 and were discharged. With the growing number of dementia patients in Japan's aging society, there is the possibility that similar situations will occur increasingly often. This case suggests that recommended infection control measures are effective for preventing the spread of COVID-19 to people staying in the same room.

Coronavirus disease 2019 (COVID-19) has spread rapidly in Japan. The purpose of this study was to report the clinical experience of our COVID-19 patients early in the pandemic and lessons from our experience. An outpatient fever clinic was established on April 7. Admission of COVID-19 patients was started on July 23. Between April 7 and September 30, there were 364 walk-in outpatients and emergency patients with fever. Polymerase chain reaction test for SARS-CoV-2 RNA or COVID-19 antigen test were performed in all patients, and all results were negative. Twenty patients with COVID-19 were admitted to a newly established dedicated COVID-19 ward. They were discharged well. There were no cases of nosocomial infection at our hospital. Length of hospitalization was correlated with serum ferritin level at admission, serum CRP level at admission, and age. More than half the patients experienced psychological stress, and COVID-19 specialized nurses experienced some stress. It is essential to set up the medical system for COVID-19 according to the trends of the disease. Creation of our original database and our “problem notebook” were useful for treatment and care of COVID-19 patients as well as for mental care of nurses.
