Abstract Disparities exist between sexes regarding tuberculosis (TB) incidence, as well disease severity and outcome. Using a nationwide TB registry database, we explored the impact of sex age on extrapulmonary (EPTB) among all enrolled patients by (1) calculating female proportion for every category according to TB-affected locations, (2) proportions EPTB stratified age, (3) conducting multivariable analysis examine likelihood, (4) assessing odds compared male reference in category....
Poor nutrition increases disease severity and mortality in patients with tuberculosis (TB). There are gaps our understanding of the effects being underweight or overweight on TB relation to sex.We generated a nationwide registry database assessed body mass index (BMI) pulmonary TB. The cause death was further classified as TB-related non-TB-related deaths. First, logistic regression analysis performed assess association between BMI (a continuous variable) mortality, subgroup analyses...
Patients with tuberculosis and diabetes have a higher risk of unfavourable anti-tuberculosis treatment outcomes. In the present study, we aimed to evaluate effects various statuses on outcomes patients pulmonary tuberculosis.
Abstract Background Screening patients with asymptomatic active tuberculosis (TB) is crucial as they can transmit the disease. Identifying risk factors for transmission essential targeted screening. Understanding how infectiousness of TB affects disease outcomes developing strategies to control spread. Methods We analyzed national Korean cohort data determine associated and clinical in pulmonary TB. The primary outcome was a factor transmission, while secondary mortality stratified by risk....

The mean age subjects 30.6 years...
The national Public-Private Mix (PPM) tuberculosis (TB) control project provides for the comprehensive management of TB patients at private hospitals in South Korea. Surveillance and monitoring under PPM are essential toward achieving elimination goals.TB is a nationally notifiable disease Korea monitored using surveillance system. Centers Disease Control Prevention quarterly generates indicators management, used to evaluate activities by central steering committee project. Based on...
BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic caused disruptions to healthcare systems and endangered the control prevention of tuberculosis (TB). We investigated nationwide effects COVID-19 on national Public-Private Mix (PPM) TB project in Korea, using monitoring indicators from Korean PPM database. METHODS: database includes data patients registered at hospitals throughout country. Data six for active cases updated between July June 2020 were collected. each cohort country...
Tuberculosis (TB) is a major cause of ill health and one the leading causes death worldwide. The first step in developing strategies to reduce TB mortality identify direct patients with risk factors for each cause.Data on systemically collected from National Surveillance System South Korea January 2019 December 2020 were included this study. We analyzed clinical characteristics associated non-TB-related deaths, including TB-related symptoms, comorbidities, radiographic microbiological...
Although the incidence of tuberculosis (TB) has decreased in South Korea, mortality rate remains high. TB is a key indicator for control interventions. The purpose this study was to assess early and TB-related during anti-TB treatment describe associated clinical characteristics.A multicenter cross-sectional performed across Korea.
