Tasks of COVID-19 prevention and control management teams at primary health care facilities in mainland China: a nationwide online cross-sectional survey.

BACKGROUND: This research aimed to investigate the tasks performed by Coronavirus Disease 2019(COVID-19) prevention and control management teams at primary healthcare (PHC) facilities during COVID-19 pandemic across the mainland China. METHODS: An online survey was performed and COVID-19 prevention and control management teams at PHC facilities were invited to participate in this research. The top 7 most important tasks in the three different periods of COVID-19 containment were selected and ranked. Participations of tasks were surveyed. RESULTS: A total of 998 valid responses (an effective rate of 99.11%) were collected. The respondents were divided into Group A (≤5 respondents within each PHC facility, n1 = 718) and Group B (> 5 respondents within each PHC facility, n2 = 280). The consensus was selected from top 7 most important tasks including screening at travel centers/intervals and screening at entry centers, at-home/centralized quarantine management, transferring, pre-examination/triage and fever sentinel surveillance clinic/fever clinic. Pre-examination/triage and fever sentinel surveillance clinic/fever clinic works became more significant in the regular prevention and control period. Adjusted analysis found that team members of Group A with a college, undergraduate college and graduate school educational background were less involved in pre-examination/triage works (aOR: 0.28; 95%CI: 0.09-0.86, P = 0.026; aOR: 0.30; 95%CI: 0.10-0.90, P = 0.031; aOR: 0.21; 95%CI: 0.05-0.82, P = 0.024). Those who were over the median age were twice more likely to be engaged in managing fever sentinel surveillance of clinic/fever clinic visitors (aOR: 2.18; 95%CI: 1.16-4.08, P = 0.015). Those being specialized in nursing and other specialties were less likely to participate in fever sentinel surveillance of clinic/fever clinic works (aOR: 0.44; 95%CI: 0.24-0.81, P = 0.009; aOR: 0.30; 95%CI: 0.16-0.58, P < 0.001). Those came from central and western China were less likely to participate in centralized quarantine management (aOR: 0.61; 95%CI: 0.38-0.98, P = 0.042; aOR: 0.64; 95%CI: 0.42-0.97, P = 0.037). Team members came from central and western China were twice less likely to participate in screening at travel centers/intervals (aOR: 1.75; 95%CI: 1.14-2.70, P = 0.011; aOR: 1.63; 95%CI: 1.07-2.48, P = 0.024). CONCLUSION: In mainland China, team members of COVID-19 prevention and control at PHC facilities are mainly responsible for screening, quarantine, transferring and monitoring during the COVID-19 pandemic. Pre-examination/triage and the fever sentinel surveillance clinic/fever clinic were gradually valued. Team members with lower educational background are competent in pre-examination/triage works, but more experienced general practitioners are more likely to be in charge of fever sentinel surveillance clinic/fever clinics work. The necessity of COVID-19 prevention and control management teams to participate in screening at travel centers/intervals is subjected to further discussions.

[Baihe Yuzi Prescription improves asthenospermia by up-regulating the expression of CFTR in the sperm].

OBJECTIVE: To observe the therapeutic efficacy of Baihe Yuzi Prescription (BYP) in the treatment of clinical syndrome-free asthenospermia and its effects on semen parameters, sperm DNA fragmentation index (DFI) and the expression of the cystic fibrosis transmembrane conductance regulator (CFTR) in the sperm. METHODS: We randomly divided 112 patients with clinical syndrome-free asthenospermia into a control group (n = 55) and an experimental group (n = 57), the former treated orally with L-carnitine liquid combined with vitamin E capsules and the latter with BYP in addition, both for 3 months. After treatment, we obtained the total sperm count, sperm motility, percentages of progressively motile sperm (PMS) and morphologically normal sperm (MNS), sperm DFI and expression of CFTR in the sperm, and compared the above parameters between the two groups of patients before and after medication. RESULTS: The total effectiveness rate was significantly higher in the experimental group (82.46%) than in the control (65.45%) (P < 0.05). Compared with the baseline, the patients in the experimental group showed significant improvement after treatment in the total sperm count (��53.5��3.5�� vs ��86.5��3.9�� ��106, P < 0.05), sperm motility (��23.5��3.5��% vs ��38.8��3.7��%, P < 0.05), PMS (��20.1��3.2��% vs ��30.3��3.3��%, P < 0.05), MNS (��2.3��0.3��% vs ��3.9��0.4��%, P < 0.05), sperm DFI (��37.3��3.1��% vs ��25.2��3.4��%, P < 0.05) and the expression of CFTR (P < 0.05), and even better improvement than the controls in sperm motility (��23.8��3.7��% vs ��30.2��3.4��%, P < 0.05), PMS (��19.6��3.1��% vs ��25.3��2.9��%, P < 0.05), MNS (��2.4��0.4��% vs ��3.1��0.3��%, P < 0.05), and sperm DFI (��36.6��3.3��% vs ��30.3��3.1��%, P < 0.05). The total sperm count and the expression of CFTR, however, were not significantly improved in the control group after treatment (P > 0.05). CONCLUSION: Baihe Yuzi Prescription can increase sperm count and motility, improve sperm morphology and DFI in patients with clinical syndrome-free asthenospermia, which may be related to the up-regulated expression of CFTR in the sperm.

Clostridium difficile infection associated with antituberculous agents in a patient with tuberculous pericarditis.

Clostridium difficile can cause pseudomembranous colitis (PMC). Antimicrobial agent exposure is a risk factor for Clostridium difficile-associated disease, whereas the use of antituberculous (anti-TB) agents is not. We herein report a case of PMC-associated with antituberculous therapy. A 63-year-old woman with tuberculous pericarditis treated with anti-TB agents was admitted for abdominal pain and diarrhea. On colonoscopy, mucoid exudate and yellowish plaque lesions were observed. The anti-TB agents were discontinued, and the patient was treated with metronidazole and clostridium butyricum. Her symptoms were relieved and did not recur when the anti-TB agents were restarted. In this report, we review the literature and discuss the pathogenesis, clinical manifestations, diagnosis and treatment of this case.
