The purpose of this study was to evaluate the effects of highly concentrated enteral nutrition (ENORAS®, Otsuka Pharmaceutical Factory, Tokushima, Japan; hereinafter, ED) on the maintenance of nutritional status and bodyweight in chemotherapy-treated patients with gastrointestinal cancer who received ED between July 2019 and January 2020. For 21 patients (15 men and 6 women, age range: 57-87 years old), we investigated serum albumin level, cholinesterase level, lymphocyte count, hemoglobin level, and bodyweight at baseline and after receiving ED. None of the patients showed any differences in albumin level, cholinesterase level, lymphocyte count, hemoglobin level, or bodyweight before and after receiving ED. Survivors had significantly favorable changes in cholinesterase level compared with non-survivors (p=0.0258). The group that received ED for 30 days or longer tended to show more favorable changes in bodyweight than the group that received ED for less than 30 days (p=0.0696). The group with stage I-III disease had more favorable changes in albumin level than the group with stage IV disease or recurrence (p=0.0932). Our results suggest that the ED is useful for helping to maintain nutritional status and bodyweight in chemotherapy-treated patients with gastrointestinal cancer.

An 81-year-old man who visited a local physician for evaluation of hoarseness was admitted to our hospital for management of a thoracic aortic aneurysm. Careful examination revealed a thoracic aortic aneurysm, aortic regurgitation, and left ventricular aneurysm. We performed total arch replacement using a frozen elephant trunk prosthesis (combined right axillary artery bypass and coil embolization), aortic valve replacement, papillary muscle approximation, and a septal anterior ventricular exclusion operation. The patient's postoperative course was uneventful, and he was discharged on the 25th postoperative day. A Kommerell diverticulum is located at the origin of an aberrant subclavian artery, and subclavian artery reconstruction via thoracotomy is challenging in such cases. Although increasing numbers of thoracic endovascular aortic repairs have been performed in recent years, the procedure is associated with complications such as endoleak and aortic esophageal fistula, and the surgical risk-benefit ratio should be carefully determined. We report a case of safe non-anatomical subclavian artery reconstruction and coil embolization.

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.
