RESUMEN
BackgroundPatients with the 2019 coronavirus disease (COVID-19) have different degrees of psychological pain, such as anxiety and depression, which may related to their prognosis. Psychological intervention can be conducted in different ways to improve psychological pain and improve the treatment effect. ObjectiveThe present study aimed to investigate and analyze the psychological status of patients with COVID-19 during the course of illness, and to evaluate the effect and influencing factors of psychological crisis intervention, so as to explore the effective mode of clinical psychological intervention in acute patients under isolation environment. MethodsA total of 143 persons participated in the study, including 26 patients diagnosed with COVID-19 in the isolation ward (COVID-19 group), 87 patients with general pneumonia in the observation ward (General Pneumonia group) and 30 healthy volunteers (Normal group). All the patients in the ward received comprehensive psychological intervention, including telephone psychological counseling (active and passive), self-adjustment of written materials and one-to-one psychological crisis intervention. Hamilton depression scale (HAMD) and Hamilton anxiety scale (HAMA) were used to evaluate the mental health status of all patients on the day of admission and 1 week after treatment. ResultsThe scores of HAMA and HAMD of all patients (including isolation ward and observation ward) were significantly higher than the healthy volunteers at the time of admission. The total score of HAMA and HAMD in CVOID-19 group were both higher than that General Pneumonia group. After 1 weeks hospitalization with comprehensive psychological intervention, the scores of HAMA and HAMD in CVOID-19 group were significantly decreased. ConclusionPatients those who diagnosed with COVID-19 in the isolation ward and/or general pneumonia in observation ward have different degrees of anxiety, depression and sleep problems. While receiving antiviral treatment, patients also need psychological intervention. Comprehensive psychological intervention model has been proved to be effective.
RESUMEN
BackgroundSo far, the psychological impact of COVID-19 epidemic among family members of Health care workers (HCWs) in China has been neglected. The present cross-sectional study aimed to investigate the mental health status and related factors of families of HCWs in Designated Hospitals in Ningbo, China. MethodFamily members of HCWs working in five designated hospitals in Ningbo, China were recruited between February 10th and 20th, 2020. Information on demographic variables, the COVID-19-related events in the lives, knowledge of COVID-19 and the working status of family members (that is, HCWs) was collected using online self-administered questionnaires. The mental health status were assessed using the Chinese version of Patient Health Questionnare-9 (PHQ-9) and Chinese version of Generalized Anxiety Disorder-7 (GAD-7). Multivariable logistic regression analyses were conducted to identify the main factors associated with the mental health conditions. ResultsA total of 822 participants completed questionnaires correctly. (response rate of 95.80%). The overall prevalence of GAD and depressive symptoms were 33.73%, and 29.35%, respectively. More times (hours) to focus on the COVID-19 (Odd ratio (OR)=1.215, 95% confidence interval (CI):1.061-1.391), family members (that is, HCWs) directly contact with confirmed or suspected COVID-19 patients (OR=1.477, 95%CI:1.069-2.040) were risk factors for GAD, while higher participants self-reported safety score for protective equipment of HCWs (OR=0.807, 95%CI:0.700-0.930) was a protective factor. More times (hours) to focus on the COVID-19 (OR=1.215, 95%CI:1.061-1.391), longer average working times per week for family members (that is, HCWs) (OR=1.017, 95%CI:1.005-1.029), being parents and other next of kin of HCWs were risk factors for depressive symptoms (OR=3.526, 95%CI:1.609-7.728 and OR=1.639, 95%CI:1.096-2.451, respectively). In addition, compared with participants who were HCWs, participants who were enterprise workers and were more likely to develop depressive symptoms(OR=1.750, 95%CI:1.104-2.776), while who were government employees or institutions employees were less likely to suffer depressive symptoms (OR=0.529, 95%CI:0.286-0.977). ConclusionsPsychological responses to COVID-19 have been dramatic among family members of HCWs during the rising phase of the outbreak. Our findings provide strong evidence to pay more attention on the mental health status of this vulnerable but often unseen populations during COVID-19 epidemic.
RESUMEN
Basic and cIinicaI studies demonstrate that depression is associated with abnormaI neuraI pIasticity in some brain regions,incIuding the prefrontaI cortex and hippocampus. Brain-derived neurotro-phic factor(BDNF)and its signaIing pathways pIay a cruciaI roIe in reguIating neuraI pIasticity and deveI-opment of depression. Ketamine or scopoIamine can produce a quick and sustained antidepressant effect,and both can quictIy activate BDNF-signaIing pathways reIated to neuraI pIasticity. In order to pro-vide the theoreticaI basis for future researches on new antidepressants,the neuraI pIasticity mechanisms of faster-onset antidepressants are reviewed in this paper.
RESUMEN
Objective To investigate the effects of estradiol replacement therapy on novel-object recognition and extinction of conditioned fear memory in ovariectomized (OVX) rats.Methods Sixty sexually mature (>90 days) female SD rats weighing 250g-300g were used as subjects.The rats were randomly divided into 7groups as following:OVX with low dose of estradiol replacement (OVX + LD,0.1 mg · kg-1),medium dose (OVX + MD,0.3mg · kg-1) and high dose (OVX + HD,0.9mg · kg-1),estradiol replacement with medium dose at 2 weeks after OVX (MD + 2W) and 4 weeks after OVX (MD + 4W),OVX group and Sham group (SH).According to the different dose and time schedules,each group was administrated estradiol or vehicle via subcutaneous injection on the dorsal side of the rat.Estradiol maintained for one month after the surgery,and then the novel-object recognition and extinction of conditioned fear memory were tested.Results (1) The rats after OVX (5.83 ±4.5)s showed access-dependent impairments on novel-object recognition ((5.83 ± 4.5)s vs(27.14 ± 6.6)s,P <0.01) and the estradiol replacement therapy can reverse this impairment,but not in the HD group.There was an increase of the ability on novel-object recognition in group LD and MD + 2W as compared with group OVX,but the difference was not statistically significant (P > 0.05).Moreover,group MD (27.86 ± 2.6)s had a significant difference compared with group OVX (P < 0.05).(2) The conditioned fear memory of rats after OVX (21.67 ± 2.0) %showed significantly lower than group SH (56.81 ± 4.6) % (P < 0.01).Chronic administration with estradiol enhanced acquisition of context fear,respectively (P < 0.01),but except group HD and group MD + 4W.The group HD(18.43 ± 1.1)% was negatively enhanced and the group MD +4W(25.25 ±2.5)% was no difference compared with group OVX.(3) On extinction of conditioned fear memory,the OVX rats produced significantly less freezing by fear context (F =3.337,P < 0.01),and estradiol treatment (except group MD + 4W)also facilitated the extinction of conditioned fear memory,respectively (P < 0.01).Conclusion These results demonstrate that estradiol may have a beneficial effect on the cognition function,and the improving effect is better when estradiol replacement is given at once depriving of sex hormone.
