Hospice care self-efficacy among clinical medical staff working in the coronavirus disease 2019 (COVID-19) isolation wards of designated hospitals: a cross-sectional study.

BACKGROUND: The COVID-19 pandemic has caused more than 462,417 deaths worldwide. A large number of patients with severe COVID-19 face death in hospital. Hospice care is truly a philosophy of care that delivers patient-centred care to the terminally ill and their families. Hospice care could provide many benefits for patients, families, and for hospice caregivers. The aim of this study is to investigate hospice care self-efficacy and identify its predictors among Chinese clinical medical staff in COVID-19 isolation wards of designated hospitals. METHODS: A cross-sectional design was used. The Hospice Care Self-Efficacy, Self-Competence in Death Work Scale, Positive Aspects of Caregiving, and Simplified Coping Style Questionnaires were administered between February and April 2020. A total of 281 eligible medical staff responded to the questionnaires, with a response rate of ≥78.9%. RESULTS: The mean score of hospice care self-efficacy was 47.04 (SD = 7.72). Self-efficacy was predicted by self-competence in death work (B = 0.433, P < 0.001), positive aspects of caregiving (B = 0.149, P = 0.027), positive coping (B = 0.219, P < 0.001), giving hospice care to dying or dead patients before fighting against COVID-19 (B = -1.487, P = 0.023), occupational exposure while fighting against COVID-19 (B = -5.244, P = 0.004), holding respect for life and professional sentiment as motivation in fighting against COVID-19 (B = 2.372, P = 0.031), and grade of hospital employment (B = -1.426, P = 0.024). The variables co-explained 58.7% variation of hospice care self-efficacy. CONCLUSION: Clinical nurses and physicians fighting COVID-19 reported a moderate level of hospice care self-efficacy during this pandemic. Exploring the traditional Chinese philosophy of life to learn from its strengths and make up for its weaknesses and applying it to hospice care may provide a new framework for facing death and dying during the COVID-19 pandemic. Continuous hospice care education to improve self-competence in death work, taking effective measures to mobilize positive psychological resources, and providing safer practice environments to avoid occupational exposure are also essential for the improvement of the hospice care self-efficacy of clinical nurses and physicians. These measures help caregivers deal effectively with death and dying while fighting against the COVID-19 pandemic.

Effect of maternal folic acid supplementation on prostatitis risk in the rat offspring.

PURPOSE: Folic acid (FA) intake has increased to high levels in many countries for the prevention of neural tube defects. However, the impact of excess FA intake, particularly before and during pregnancy, requires further investigation. Our aim was to investigate the effect of maternal folic acid supplementation on prostatitis risk in the rat offspring. METHODS: Female SD rats were administrated with different doses of FA by oral gavage from 2 weeks prior to mating to GD14: 0 mg/kg (distilled water), 0.2 mg/kg FA and 2.0 mg/kg FA respectively. The male rat offspring from each maternal FA group were castrated on PND56 and injected different doses of 17ß-estradiol (E2) subcutaneously for 30 days to induce prostatitis: 0 mg/kg (corn oil) and 1.25 mg/kg E2 respectively. At necropsy, the prostates were collected for histopathological analysis. Fasting blood was collected for the determination of serum E2, T, DHT, and folic acid levels. The expression of TNF-α, COX-2, and ER-α was determined by immunohistochemistry. RESULTS: High-dose (2.0 mg/kg) maternal folic acid supplementation significantly increased the proportion of prostatitis in FA(2.0) + E2(1.25) group (87.5%) compared with FA(0) + E2(1.25) group (25%). The inflammation was focal and severe, and large amounts of inflammatory cells appeared in different regions of the prostate in FA(2.0) + E2(1.25) group. The serum T, DHT, and FA levels in FA(2.0) + E2(1.25) group were significantly higher than those in FA(0) + E2(1.25) group. The expression of TNF-α, COX-2, and ER-α in three 1.25 mg/kg E2 groups presented positive, and the number and distribution of positive cells increased as FA dosage increased. CONCLUSIONS: Our findings suggest that high-dose (2.0 mg/kg) maternal folic acid supplementation significantly increases the proportion of prostatitis and the prostatic inflammation is more obvious and severe in the rat offspring.

The alteration of inflammatory markers and apoptosis on chronic prostatitis induced by estrogen and androgen.

PURPOSE: The age-related decline of the testosterone-to-estrogen (T-to-E2) ratio in serum is associated with the increased prevalence of prostatic inflammation. The goal of the study was to induce prostatic inflammation with E2 and androgen treatment and to explore the inflammatory markers and apoptosis on prostatitis. METHODS: Castrated SD rats were treated with E2 and different doses of androgens to achieve an elevated concentration of E2 and a wide range of the androgen-to-E2 ratio in serum. Inflammatory markers TNF-α, COX-2 and MIP-1α were immunohistochemically stained. Apoptosis detection was evaluated by TUNEL staining. E2, T and DHT concentrations in serum were measured, and the relative weight of the prostate and seminal vesicles were determined. RESULTS: T was anti-inflammatory at the doses which normalized or over stimulated the growth of the prostate and seminal vesicles. Experimentally, prostatitis induced by E2 alone increased the prostatic levels of the inflammatory markers TNF-a, COX-2 and MIP-1a. As signs of anti-estrogenic actions, androgens dose-dependently decreased the expression of TNF-α, COX-2 and MIP-1α. Prostatitis induced by E2 alone caused extensive apoptosis in the castrate-resistant cells and E2-induced apoptosis occurred dependently of T manipulation. CONCLUSIONS: Estrogen-alone-induced inflammatory response could promote the expression of inflammatory markers; however, T supplementation reduces the expression of inflammatory markers and E2-induced apoptosis occurs dependently on T manipulation in prostatitis.
