Psychological responses among nurses caring for patients with COVID-19: a comparative study in China.

Frontline healthcare nurses devoted themselves to deal with the outbreak of COVID-19, saving many lives. However, they are under incredible unknown psychological pressures with a considerable risk of infection. In this study, a self-administered questionnaire was used to survey 593 frontline nurses in Wuhan City and non-Hubei provinces for psychological responses from March 1 to March 10, 2020. Compared with nurses outside Hubei Province, those working in Wuhan were more likely to feel physically and mentally exhausted. Their probable depression and anxiety were significantly higher than those of nurses outside Hubei province (31.2%, 18.3% vs. 13.8%, 5.9%). Correspondingly, the depressive symptoms were more often reported in the Wuhan group (70.8% vs. 41.4%). Although Wuhan received wishes, concerns, and abundant psychological and material resources from all of the world, the survey-based study found that frontline nurses in Wuhan still had higher depression and anxiety with less social support compared with nurses from non-Hubei provinces. Unexpectedly, only 4.0% of nurses have sought psychological assistance. These findings suggested that the short-term psychological impact of frontline nurses in Wuhan during the COVID-19 outbreak was extremely high compared with nurses outside Hubei Province. This research enlightened the efficient integration of psychological resources, the optimization of the nurse emergency psychological assistance system, and the mental health care of medical staff during the outbreak of epidemics.

Analysis of Pepsin Concentration and Influencing Factors in Saliva of Elderly Nasal Feeding Patients.

BACKGROUND: Elderly patients receiving nasal feeding have weaker physiological function, and placement of a nasogastric tube weakens the natural barrier of the cardia-esophageal sphincter; therefore, the risk of gastroesophageal reflux (GER) is higher. Many studies have shown that pepsin is extremely sensitive in predicting GERD, so this study intends to investigate the level of pepsin in saliva of elderly patients with nasal feeding and analyze its influencing factors. METHODS: This was a cross-sectional study. Patients admitted to the Chinese PLA General Hospital from April 2018 to October 2018 who received nasal feeding were included. One ml of saliva was collected from each patient in while sitting during fasting in the morning and 1 hour after lunch for 3 consecutive days. Pepsin was quantified by enzyme-linked immunosorbent assay (ELISA). The patients were predivided into two groups (≥7.75µg/ml or <7.75µg/ml) based on the median pepsin. Baseline and clinical factors were compared. RESULTS: The mean age of the patients was 91.09 ± 4.91 years. There were statistical differences in diabetes and feeding methods between the two groups. There was a positive correlation between the morning and postprandial pepsin levels (r = 0.442, P < 0.001), and has no statistical difference (P = 0.175). Multivariate analysis showed that the risk factors for higher pepsin levels were diabetes (odds ratio (OR): 2.67; 95% CI: 1.225-5.819, P = 0.013) and nasal feeding methods (OR: 2.475; 95% CI: 1.183-5.180, P=0.016). CONCLUSIONS: For patients undergoing nasal feeding who are older than 80 years, the fasting and 1-hour postprandial pepsin concentration were consistent. Diabetes and feeding methods are risk factors for high pepsin levels. For the elderly over 80 years old, age has no influence on pepsin concentration.

Risk factors of ventilator-associated pneumonia in elderly patients receiving mechanical ventilation.

Purpose: The aim of this study was to verify the potential risk factors of ventilator-associated pneumonia (VAP) in elderly Chinese patients receiving mechanical ventilation (MV). The secondary aim of this study was to present logistical regression prediction models of VAP occurrence in elderly Chinese patients receiving MV. Methods: Patients (aged 80 years or above) receiving MV for ≥48 h were enrolled from the Chinese People's Liberation Army (PLA) General Hospital from January 2011 to December 2015. A chi-squared test and Mann-Whitney U-test were used to compare the data between participants with VAP and without VAP. Univariate logistic regression models were performed to explore the relationship between risk factors and VAP. Results: A total of 901 patients were included in the study, of which 156 were diagnosed as VAP (17.3%). The incidence density of VAP was 4.25/1,000 ventilator days. Logistic regression analysis showed that the independent risk factors for elderly patients with VAP were COPD (OR =1.526, P < 0.05), intensive care unit (ICU) admission (OR=1.947, P < 0.01), the MV methods (P < 0.023), the number of antibiotics administered (OR=4.947, P < 0.01), the number of central venous catheters (OR=1.809, P < 0.05), the duration of indwelling urinary catheter (OR=1.805, P < 0.01) and the use of corticosteroids prior to MV (OR=1.618, P < 0.05). Logistic regression prediction model of VAP occurrence in the Chinese elderly patients with mechanical ventilation: L o g i t   P = - 6 . 468 + 0 . 423 X 1 + 0 . 666 X 2 + 0 . 871 X 3 + - 0 . 501 X 5 + 0 . 122 X 6 + 0 . 593 X 7 + 0 . 590 X 8 + 1 . 599 X 9 . Conclusion: VAP occurrence is associated with a variety of controllable factors including the MV methods and the number of antibiotics administered. A model was established to predict VAP occurrence so that high-risk patients could be identified as early as possible.

Healthcare for servicewomen on military missions.

Increases in the number of women in critical positions on military missions place new demands for specialised healthcare services to promote performance. The main health problems servicewomen facing are musculoskeletal injuries, reproductive diseases, iron deficiency and mental health problems. Herein, we propose several suggestions based on the rich experiences of our hospital. First is to offer preventive measures for servicewomen health. Second is to equip servicewomen with portable medicine packet to treat common diseases. Third is to provide people-centred integrated care.

[The compliance in elderly male with osteoporosis treated with oral alendronate].

OBJECTIVE: To explore the compliance in elderly male with osteoporosis treated with oral alendronate and analyze the factors which affect the therapeutic compliance. METHODS: A total of 145 elderly male patients diagnosed with osteoporosis who had been initiated the treatment of oral alendronate in our clinic during January to June in 2011 were enrolled in the study. The medication compliance of one year was investigated. According to the different medication possession ratio (MPR), MPR ≥ 80% was considered as adherent and MPR < 80% was considered as non-adherent. The difference in the two groups was compared and the factors which affect the therapeutic compliance were analyzed. RESULT: A total of 139 patients had been followed up with 32 adherent cases (23.02%) and 107 non-adherent cases (76.98%). Logistic regression analysis showed the factors which affected the therapeutic compliance as the following: ostealgia (OR = 0.69, P = 0.043), no-reminder (OR = 1.37, P = 0.025), concern about drug related side effect (OR = 1.49, P = 0.018), more than 7 kinds of drugs (OR = 1.30, P = 0.036) and uncertain long-term effect (OR = 1.39, P = 0.021). CONCLUSIONS: Compliance of oral alendronate to treat osteoporosis in elderly male patients is poor. Ostealgia can promote the drug compliance. The factors which could decrease the drug compliance are no-reminder, concern about drug related side effect, more than 7 kinds of drugs and uncertain long-term efficacy.
