ABSTRACT
BACKGROUNDThe outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has rapidly spread globally. The laboratory diagnosis of SARS-CoV-2 infection has relied on nucleic acid tests. However, there are many limitations of nucleic acid tests, including low throughput and high rates of false negatives. More sensitive and accurate tests to effectively identify infected patients are needed. METHODSThis study has developed fully automated chemiluminescent immunoassays (CLIA) to determine IgM and IgG antibodies to SARS-CoV-2 in human serum. The assay performance has been evaluated at 10 hospitals. Clinical specificity was evaluated by measuring 972 hospitalized patients with diseases other than COVID-19, and 586 donors of a normal population. Clinical sensitivity was assessed on 503 confirmed cases of SARS-CoV-2 by RT-PCR and 52 suspected cases. RESULTSThe assays demonstrated satisfied assay precision with coefficient of variation (CV) of less than 4.45%. Inactivation of specimen does not affect assay measurement. SARS-CoV-2 IgM shows clinical specificity of 97.33% and 99.49% for hospitalized patients and normal population respectively. SARS-CoV-2 IgG shows clinical specificity of 97.43% and 99.15% for the hospitalized patients and the normal population respectively. SARS-CoV-2 IgM and IgG show clinical sensitivity of 85.88% and 96.62% respectively for confirmed SARS-Cov-2 infection with RT-PCR, of 73.08% and 86.54% respectively for suspected cases. CONCLUSIONSwe have developed fully automated immunoassays for detecting SARS-CoV-2 IgM and IgG antibodies in human serum. The assays demonstrated high clinical specificity and sensitivity, and add great value to nucleic acid testing in fighting against the global pandemic of the SARS-CoV-2 infection.
ABSTRACT
Objective To investigate the value of micro-course in colostomy patients in self-care. Methods A total of 120 patients with colostomy patients were divided into the intervention group and the control group with 60 cases each according to the first time in the hospital bed and odd number. The intervention group was given micro-course in colostomy patients discharge health education. The control group was taken the traditional health education missionary single conduct health education of discharged. The self-efficacy (divided stoma care effectiveness and social effectiveness of two dimensions and six separate entries, score 28-140 points. Using five no confidencethere a little confidence some of confidencequite confident or very confident scoring 1-5 points) and stoma care skills (including two parts, a total of 18 entries, each entry method using Likert scale of 51-5 points representing very unskilledsomewhat skilledordinary skillskilled and very skilled, score 18-90 points, higher scores indicate better skills) of patients after 3 months of discharge between the two groups were compared and evaluated. Results After 3 months of discharge, the self- efficacy scores of the intervention group were evaluated with respect to stoma care, social performance, diet choice, confidence in sex life, confidence in sexual life, confidence in physical activity, confidence in vitality and confidence in self-care (53.17±3.54), (38.62±5.25), (3.45 ± 1.06), (2.43 ± 1.06), (2.22 ± 0.86), (2.88 ± 0.94), (3.52 ± 0.89), (3.88 ± 0.64) points, respectively, compared with the control group (50.45 ± 4.79), (35.33 ± 3.42), (3.03±1.15), (1.77±0.81), (1.78±0.72), (2.47±0.96), (3.02±0.70), (3.40±0.81) points, there were significant differences (t=-4.366--2.076, all P<0.05) . According to the comparison of stoma nursing skills, the score of stoma care and the related knowledge of stoma care were (36.33±4.21), (37.13±3.85) points in the intervention group, and (34.22±3.87), (31.32±4.95) points in the control group, and there were statistically significant difference (t=-3.140,-7.741, P < 0.05). Conclusions Colostomy patients discharged from hospital health education classes in the use of micro-course, can effectively improve patients' self-efficacy and ostomy care capacity, enhance the quality of life.
ABSTRACT
Objective To study the effect of network peer education on the 131I treatment adherence in patients with thyroid cancer.Methods A total of 120 patients with thyroid cancer who performing 131 I treatment from April 2012 to April 2014.They were divided into intervention group 61 cases and control group 59 cases according to the hospital ward number.Control group was given routine health education and intervention group was given network peer education.The data from the habits,drug therapy,grasp the situation,the equivalent monitoring of the relevant knowledge of 4 different dimensions of treatment adherence for patients were investigated and compared before discharge by using questionnaire and examination method.Results The incidence of the good habits,drug therapy,grasp the situation,and the equivalent monitoring reaching the standard were 96.7％(59/61),98.4％(60/61),96.7％(59/61),100.0％(61/61) in intervention group,and 54.2％(32/59),76.3％(45/59),79.7％(47/59),89.8％(53/59) in control group,there were significant differences,x2=29.54,13.38,8.47,4.56,P＜0.01 or ＜0.05.Conclusion Network peer education for patients with thyroid cancer during the 131I treatment can effectively improve the patient's treatment adherence,has positive significance for the treatment.
