Objective: To explore the mental health status and influencing factors of medical staff after blood-borne occupational exposure, and to provide scientific basis for effective psychological intervention. Methods: From January 2017 to December 2018, 178 medical staff with blood-borne occupational exposure in three hospitals of Shandong Province were collected as the contact group, and 100 routine medical staff as the control group during the same period. Questionnaires were conducted among medical staff in the two groups, including general information questionnaire, symptom checklist 90 (SCL-90) , post-traumatic stress disorder self-rating scale (PCL-C) , coping style scale (CPS) , social support scale (SSRS) . The basic situation and mental health level of medical staff in the two groups, as well as the coping and social support status of medical staff exposed to hematogenous occupational exposure were analyzed. Relevant influencing factors. Results: The total score of SCL-90 was 1.66+0.33, 45 (38.14%) were positive, and 21 (21.00%) were positive in the control group. The difference was statistically significant (χ²=7.529, P<0.05) . Compared with the control group, the scores of SCL-90 somatization, obsessive-compulsive symptoms, depression, anxiety, hostility, paranoia and total scores of medical staff in the exposure group increased significantly (P<0.05) . The total PCL-C score of exposure group was 36.84+9.50, PTSD positive 47 (39.83%) and control group 13 (13.00%) . The difference was statistically significant (χ²=19.534, P<0.05) . Compared with the control group, PCL-C re-experience, avoidance, vigilance factor scores and total scores of medical staff in the contact group increased significantly (P<0.05) . The problem solving, help seeking and subjective support of the medical staff in the positive mental health group with blood-borne occupational exposure were significantly lower than those in the negative group, while self-blame, fantasy and withdrawal were significantly higher than those in the negative group (P<0.05) . The mental health level of medical staff with occupational exposure was negatively correlated with problem solving, help seeking and subjective support, and positively correlated with self-blame, fantasy and withdrawal (P<0.05) . Problem solving, help seeking and subjective support were protective factors of mental health (OR=2.121, 1.616, 1.371) , and self-blame and withdrawal were risk factors of mental health (OR=0.160, 0.484) . Conclusion Medical personnel exposed to blood-borne occupational exposure are prone to psychological problems and PTSD. Solving problems, seeking help and subjective support are protective factors for mental health, while self-blame and withdrawal are risk factors for mental health.

Fungal infections of the digestive tract in children can be caused by a variety of fungi, the most common of which are Candida and Aspergillus.Occurrence of invasive fungal infections is dependent on numerous factors including geographic location and routes of exposure, and host factors, such as predisposing conditions, high-risk medications, or underlying medical comorbidities that modulate overall immune function.However, advances in DNA and ribosomal RNA sequencing and serologic testing have led to shifts in how gut fungal microbiota are identified and in diagnosing opportunistic infections.This article will briefly expound the common pathogens, risk factors, clinical manifestations, diagnosis, and treatment of gastrointestinal fungal infections in children.

Objective:To investigate the knowledge of the disease and demands of medical intervention in high-risk individuals of arteriosclerotic cardiovascular diseases (ASCVD).Methods:The 10-year ASCVD incidence risk prediction model was used to screen ASCVD high-risk individuals from Luohu district of Shenzhen city. From October 2018 to April 2019,a semi-structured in-depth interview was conducted among ASCVD high-risk individuals selected by stratified sampling method according to age, gender and educational level. The original data were analyzed with Colaizzi′s seven-step analysis method.Results:Total 37 interviewees were enrolled with an average age of (65.2±8.9) years and with an average ASCVD risk value of (14.2±3.2). Three themes were extracted from the interview, including: (1) Majority interviewees had better Knowledge about the hazards and risk factors of ASCVD; (2) Most of the interviewees had lower medical demands; (3) The interviewees were more likely to focus on symptomatic diseases or diseases disturbing them.Conclusions:The asymptomatic high-risk ASCVD individuals generally have better awareness of ASCVD and less demands for intervention. The result indicates that for health education, not only the knowledge, but also the attitude and behavior should be enhanced.
