Background The outbreak of COVID-19 has led to international concern. We aimed to establish an effective screening strategy in Shanghai, China, to aid early identification of patients with COVID-19. MethodsWe did a multicentre, observational cohort study in fever clinics of 25 hospitals in 16 districts of Shanghai. All patients visiting the clinics within the study period were included. A strategy for COVID-19 screening was presented and then suspected cases were monitored and analysed until they were confirmed as cases or excluded. Logistic regression was used to determine the risk factors of COVID-19. Findings We enrolled patients visiting fever clinics fromJan 17 to Feb 16, 2020. Among 53 617 patients visiting fever clinics, 1004 (1•9%) were considered as suspected cases, with 188 (0•4% of all patients, 18•7% of suspected cases) eventually diagnosed as confirmed cases. 154 patients with missing data were excluded from the analysis. Exposure history (odds ratio [OR] 4•16, 95% CI 2•74-6•33; p<0•0001), fatigue (OR 1•56, 1•01-2•41; p=0•043), white blood cell count less than 4 × 10⁹ per L (OR 2•44, 1•28-4•64; p=0•0066), lymphocyte count less than 0•8 × 10⁹ per L (OR 1•82, 1•00-3•31; p=0•049), ground glass opacity (OR 1•95, 1•32-2•89; p=0•0009), and having both lungs affected (OR 1•54, 1•04-2•28; p=0•032) were independent risk factors for confirmed COVID-19.Interpretation The screening strategy was effective for confirming or excluding COVID-19 during the spread of this contagious disease. Relevant independent risk factors identified in this study might be helpful for early recognition of the disease.
ABSTRACT.Although new chemotherapeutic drugs have been applied constantly, their efficacy for non-small cell lung cancer (NSCLC) is still not satisfactory. In recent years, epidemiological investigations have shown that lung cancer may be induced by chronic Chlamydia pneumoniae (Cpn) infection, since stable high titers of Cpn antibodies, especially IgA, are a hallmark of chronic infections. Azithromycin is commonly used for the treatment of Cpn infections; however, there are only few reports regarding the application of azithromycin (A) combined with paclitaxel and cisplatin (TP) for advanced NSCLC. Considering that patients with NSCLC have a higher rate of Cpn infection, we proposed to employ azithromycin for Cpn infection in chemotherapy for advanced NSCLC. The aim of this study was to explore the effects of azithromycin on chemotherapy for NSCLC. A total of 86 patients with stage III-IV NSCLC were randomly divided into TP and ATP groups; the characteristics of patients in the two groups showed no significant differences. The TP group was treated with paclitaxel and cisplatin, and the ATP group was treated with Azithromycin, paclitaxel and cisplatin in lung cancer azithromycin combined with TP for at least 4 weeks, followed by evaluation and comparison of efficacy, side effects and patients' quality of life before and after chemotherapy between the two groups. Testing for Cpn infection revealed a significant difference in the case number before and after therapy in the ATP group (P < 0.01) compared with the TP group (P > 0.05), and a statistical difference was observed (P < 0.01) between the ATP and TP groups after treatment. The changes in quality of life of patients after two different chemotherapy regimens were statistically significant (P < 0.05), but there was a significant difference in only cognitive function after treatment. The changes in symptom scores of patients after the two different chemotherapy regimens were statistically significant (P < 0.05), but there was a significant difference in only shortness of breath and cough after treatment. Kaplan-Meier estimate was utilized to describe the survival function of patients in the two groups. The median survival time was 12.0 months for the TP group and 13.0 months for the ATP group. One-year survival rates of the TP and ATP groups were 45.0 and 75.0%, respectively, which were significantly different (P < 0.05). Our study of azithromycin+paclitaxe l+cisplatin on stage III-IV NSCLC patients achieved favorable results in terms of side effects and overall survival.
This nationwide population-based cohort study investigated the risk of tuberculosis (TB) in patients with end-stage renal disease (ESRD) and receiving dialysis. The evaluations included 4131 incident ESRD patients receiving dialysis and 16,524 age- and gender-matched controls, recruited between 1998 and 2009. We used Cox proportional hazards regression analysis to measure the association between TB and ESRD. Compared to the controls, the ESRD cohort had a significantly higher risk of TB within 1 year [incident rate ratio (IRR) 4.13], and 1-2 years (IRR 2.12), of occurrence of ESRD. The Cox proportional hazards model revealed that ESRD [hazard ratio (HR) 2.40], age >65 years (HR 2.41), male sex (HR 1.94), diabetes mellitus (HR 1.36), silicosis (HR 7.70) and chronic obstructive pulmonary disease (HR 1.61) are independent risk factors for TB. Patients with ESRD are associated with an increased risk of TB, and should thus be monitored more carefully for TB, especially within 2 years of onset of ESRD.
Background: The COVID-19 pandemic is a significant health threat. Health care worker (HCWs) are at a significant risk of infection which may cause high levels of psychological distress. The aim of this study was to investigate the psychological impact of the COVID-19 on HCWs and factors which were associated with these stresses during the first outbreak in Shanghai.Methods: Between February 9 and 21, 2020, a total of 3,114 frontline HCWs from 26 hospitals in Shanghai completed an online survey. The questionnaire included questions on their sociodemographic characteristics, 15 stress-related questions, and General Health Questionnaire-12 (GHQ-12). Exploratory factor analysis was applied to the 15 stress-related questions which produced four distinct factors for evaluation. Multiple linear regression models were performed to explore the association of personal characteristics with each score of the four factors. Binary logistic analysis was used to explain the association of personal characteristics and these four factors with the GHQ-12.Results: There were 2,691 valid surveys received. The prevalence of emotional distress (defined as GHQ-12 ≥ 12) was noted in 47.7% (95%CI:45.7–49.6%) HCWs. Females (OR = 1.43, 95%CI:1.09–1.86) were more likely to have a psychological distress than males. However, HCWs who work in secondary hospitals (OR = 0.71, 95% CI:0.58–0.87) or had a no contact history (OR = 0.45, 95%CI: 0.35–0.58) were less likely to suffer psychological distress. HCWs who were nurses, married, and had a known contact history were highly likely to have anxiety. HCWs working at tertiary hospitals felt an elevated anxiety regarding the infection, a lack of knowledge, and less protected compared to those who worked at secondary hospitals.Conclusions: Our study shows that the frontline HCWs had a significant psychosocial distress during the COVID-19 outbreak in Shanghai. HCWs felt a lack of knowledge and had feelings of being not protected. It is necessary for hospitals and governments to provide additional trainings and psychological counseling to support the first-line HCWs.
