Differences in the diurnal variation of salivary stress biomarkers during the coronavirus (COVID-19) pandemic between telecommuters and office workers.

OBJECTIVES: It is necessary to objectively assess the stress state of workers, from the standpoint of holistic palliative care, in order to determine how the rapid change in work styles in the "live with coronavirus era"-in which people will coexist and live with the coronavirus (COVID-19)-will affect their physical and mental health. The aim of this study is to assess the impact of rapid changes in work patterns during the COVID-19 pandemic on the neuroendocrine stress response of workers. DESIGN AND METHODS: A total of sixteen subjects, 9 telecommuters (2 males, 7 females; age, 37.1±2.6 years) and 7 office workers (3 males, 4 females; age, 37.3±3.0 years) who provided their informed consent were enrolled in this prospective observational study. Saliva was collected four times a day (after waking, noon, evening, and before bedtime) and three times a week (Monday, Wednesday, and Friday) during May and June 2020. The saliva samples were stored at -20°C until measurement. Saliva components were analyzed by ELISA for cortisol, melatonin, s-IgA, and oxytocin. RESULTS: The diurnal variation of salivary components between telecommuting and office work groups was investigated. Cortisol showed diurnal variation with higher secretion during waking hours and lower secretion toward nighttime in both groups, and no modulation was observed. In the office work group Melatonin showed diurnal variation, with increased secretion at night. In contrast, the telecommuting group showed modulation, with higher secretion at waking and lower secretion at night. s-IgA showed diurnal variation with a high level at waking and a low level thereafter in both groups, and no modulation was observed. The telecommuting group showed higher oxytocin levels in comparison to the office work group. CONCLUSIONS: These results suggest that the absence of commuting in the telecommuting group reduces anxiety due to infection, and that the diurnal variation of melatonin may be due to the alteration of circadian rhythm caused by being at home all day.

Brief psychotic disorder mimicking the symptoms of cerebrovascular attack evoked by symptoms that symbolized death in a patient with terminal stage stomach cancer: case report and review of the literature.

OBJECTIVE: We report here a terminally ill patient with stomach cancer who developed a brief psychotic disorder mimicking cerebrovascular attack after a short episode of nasal bleeding. Close examination of the patient revealed that nasal bleeding was an event that symbolized deterioration of the general condition leading to death for the patient. METHODS: A 77-year-old male, who was diagnosed as having stomach cancer and was receiving palliative care, presented with tremor and insomnia just after a short episode of nasal bleeding and showed reduced response to stimuli mimicking cerebrovascular attack. Laboratory data were unremarkable. The next day, catatonic behavior developed. He had no history of psychiatric illness or drug or alcohol abuse. After receiving haloperidol, psychiatric symptoms disappeared and he returned to the previous level of functioning within 3 days. The patient explained that he had seen a patient whose general condition deteriorated after nasal bleeding and regarded nasal bleeding as a symptom of deteriorating general condition leading to death and thereafter became afraid of the nasal bleeding. RESULTS AND SIGNIFICANCE OF RESULTS: Although, nasal bleeding is common and usually not severe in medical settings, for the patient, it was an event that symbolized deterioration of the general condition leading to death. Brief psychotic disorder in cancer patients is rare in the literature, although patients receiving terminal care share various kinds of psychological burden. Medical staff in the palliative care unit should be aware of the psychological distress experienced by each patient and consider brief psychotic disorder as part of the differential diagnosis when patients show unexplained neurological-like and/or psychiatric symptoms.

Development of Wernicke encephalopathy in a terminally ill cancer patient consuming an adequate diet: a case report and review of the literature.

Malignancy-associated primary thiamine deficiency has been documented in several experimental tumors, clinical case reports, and in patients with fast growing malignancies. We report a terminally ill cancer patient who developed delirium. Close examination of the patient demonstrated that delirium was caused by thiamine deficiency, although she had been consuming an average of 990 cal/day for the past 3 weeks. Malabsorption or consumption by the tumor was considered the mechanism of thiamine deficiency. Early recognition and subsequent treatment resulted in successful palliation of delirium. In terminally ill cancer patients, clinicians must remain aware of the possibility of Wernicke's encephalopathy, when the patients develop unexplained delirium, even if the patient has been consuming adequate amounts of food. Early intervention may correct the symptoms and prevent irreversible brain damage, and the quality of life for the patient may improve.

Spouse caregivers of terminally-ill cancer patients as cancer patients: a pilot study in a palliative care unit.

OBJECTIVE: It is known that families of terminally-ill cancer patients show levels of emotional and functional disruption and are called "second order patients," however, little is actually known about the health problems of family members, especially in terms of cancer. METHODS: This study reviewed the family histories of terminally-ill cancer patients in a palliative care unit and investigated cancer related health problems of the spouses of terminally-ill cancer patients. RESULTS: We investigated the past medical history of 125 spouses of terminally-ill cancer patients and found that five spouses had a past medical history of cancer. In these five spouses, the duration of illness, present status of treatment and physical condition were reviewed from the database. Of these five spouses, three patients continued to attend an outpatient clinic regularly for checkup and one patient was hospitalized for nephrectomy. Two spouses did not have physical symptoms that made them unable to provide direct care for the terminally-ill spouses, while three could not provide care because of their own physical symptoms derived from cancer. SIGNIFICANCE OF RESULTS: Our findings indicated that some of the spouses of terminally-ill cancer patients are not only "second order patients" but also "cancer patients." Our findings also suggest that some spouses of terminally-ill cancer patients might experience distress both as a cancer patient and as a spouse and may need care both as a cancer patient and as a spouse.
