ABSTRACT
Objective@#To analyze the characteristics and influencing factors of care-seeking delay of adolescent tuberculosis patients in Dongguan City from 2009 to 2018, so as to provide theoretical basis for the tuberculosis control.@*Methods@#The study participants were 8 899 adolescent tuberculosis patients in Dongguan from 2009 to 2018. The Rank-sum test and multiple linear regression were used to analyze the influencing factors of care-seeking days, and the χ 2 test and Logistic regression were used to analyze the influencing factors of care-seeking delay.@*Results@#The median care-seeking days among adolescent tuberculosis patients were 18(6-46) days in Dongguan City from 2009 to 2018, and the prevalence of the care-seeking delay was 56.6%. Multiple linear regression indicated that care-seeking delays were positively associated with being women (B=0.20), living in rural areas (B=0.10), pathogen-positive patients (B=0.69), patients from 2014 to 2018 (B=0.21), and junior school students (B=0.98). Multivariate Logistic regression indicated that care-seeking delay were positively associated with being women (OR=1.35, 95%CI=1.23-1.47), living in rural areas (OR=1.21, 95%CI=1.08-1.37), pathogen-positive patients (OR=2.51, 95%CI=2.26-2.79), patients from 2014 to 2018 (OR=1.24, 95%CI=1.14-1.35), junior-school students (OR=7.58, 95%CI=1.45-39.65), high-school students (OR=5.26, 95%CI=1.04-26.52), university students (OR=7.06, 95%CI=1.39-35.99), and non-students (OR=5.23, 95%CI=1.05-26.08)(P<0.05).@*Conclusion@#The prevention and control of tuberculosis among adolescent patients in Dongguan urgently needs to be strengthened. In the future, attention should be paid to the prevalence of care-seeking delay among female, rural, and student tuberculosis patients, and a reasonable prevention and control policy for adolescent patients should be formulated.
ABSTRACT
Objective To compare the value of pacemaker implantation using the subclavian vein (SCV) puncture and thecephalic vein(CV) cutdown approach.Methods One hundred and forty-six patients were randomized into SCV group (98 patients) and CV group (48 patients).We observed the success rate,surgery duration,fluoroscopy time and complications of the two groups.Results The SCV group had significantly higher success rate,shorter duration of surgery and fluoroscopy than the CV group (success rate:100％ (98/98) vs.89％ (43/48),x2 =10.5,P ＜ 0.05 ; duration of surgery:(118 ± 35) min vs.(256 ± 75)min,t =12.12,P ＜0.01 ; duration of fluoroscopy:(15 ±5) min vs.(35 ± 10) min,t =13.08,P ＜0.01).Both groups had one case who developed compilations which were pocket hematoma and wire electrode dislocation respectively.The rate of complications was not significantly different between the two groups (P ＞ 0.05).Conclusion The SCV approach should be considered a preferable access in pacemaker implantation.
