Burden of tuberculosis in Serbia

Exploring the Impact of Silicosis Incidence on Tuberculosis Mortality and Morbidity: A Multi-Country Study

INTRODUCTION

There are several risk factors attributed to tuberculosis (TB) mortality and morbidity. There are few studies and systematic reviews showing the association of silicosis and tuberculosis at a country level. Very limited studies have been conducted using multi-country data in studying the association of incidence of silicosis with TB mortality and morbidity. Hence, the aim of this research was to explore the association of incidence of silicosis and other important risk factors with TB mortality and morbidity using multi-country data.

METHODS

Data from 217 WHO region countries were utilized, sourcing TB-related statistics from the Institute of Health Metrics and Evaluation and additional risk factors from the Demographic and Health Survey, Global Burden of Disease, and World Bank for 2019. Regression analysis was conducted to examine the association between silicosis incidence and TB outcomes.

RESULTS

The study found an average silicosis incidence of 121.92 per 100,000 population. Additionally, 62.69% of the sample population are exposed to air pollution from solid fuel cooking. Sanitation access stands at an average of 59.67%. Regression outcomes indicate that while alcohol consumption's influence on TB is not statistically significant, a unit increase in silicosis incidence significantly elevates TB deaths (235.9, p = 0.005), YLL (9399.3, p = 0.011), and YLD (910.8, p = 0.002).

CONCLUSION

The burden of silicosis is found to be one of the important determinants of deaths, YLL, and YLD due to tuberculosis. Country-specific strategies to prevent and control silicosis is a need of the hour.

Burden of tuberculosis trends in a Brazilian southern state

INTRODUCTION

The burden of tuberculosis has been scarcely explored in developing countries.

OBJECTIVE

To estimate the trend of the burden of tuberculosis in the state of Santa Catarina, southern Brazil, from 2007 to 2011.

METHODS

Epidemiological time-series study on tuberculosis notifications and deaths reported in the Disease Notification System and the Mortality Information System between 2007 and 2011. Crude rates of Disability-Adjusted Life Years (DALY) and subcomponents were calculated and standardized by gender and age groups. Segmented linear regression was used to estimate the trends for burden of tuberculosis during the study period.

RESULTS

There were 696 deaths and 8,598 notifications during the study period. The highest rate was found in 2009, with 91.8 DALY/100,000 inhabitants, and the lowest in 2007, with 67.2 DALY/100,000 inhabitants. The highest burden was among men in economically active age groups. The study showed a non-significant increase of 3.8% per year in DALY rates.

CONCLUSION

The burden of tuberculosis remained stable in Santa Catarina, Brazil between 2007 and 2011.

The burden of disease due to tuberculosis in the state of Santa Catarina, Brazil

OBJECTIVE

To estimate the burden of disease due to tuberculosis in the state of Santa Catarina, Brazil, in 2009.

METHODS

This was an epidemiological study with an ecological design. Data on tuberculosis incidence and mortality were collected from specific Brazilian National Ministry of Health databases. The burden of disease due to tuberculosis was based on the calculation of disability-adjusted life years (DALYs). The DALYs were estimated by adding the years of life lost (YLLs) and years lived with disability (YLDs). Absolute values were transformed into rates per 100,000 population. The rates were calculated by gender, age group, and health care macroregion.

RESULTS

The burden of disease due to tuberculosis was 5,644.27 DALYs (92.25 DALYs/100,000 population), YLLs and YLDs respectively accounting for 78.77% and 21.23% of that total. The highest rates were found in males in the 30-44 and 45-59 year age brackets, although that was not true in every health care macroregion. Overall, the highest estimated burden was in the Planalto Norte macroregion (179.56 DALYs/100,000 population), followed by the Nordeste macroregion (167.07 DALYs/100,000 population).

CONCLUSIONS

In the majority of the health care macroregions of Santa Catarina, the burden of disease due to tuberculosis was concentrated in adult males, the level of that concentration varying among the various macroregions.

Tuberculosis incidence in elderly in Serbia: key trends in socioeconomic transition

AIM

To examine tuberculosis incidence rates among the elderly in Central Serbia in 1992-2006 period, which was characterized by socioeconomic crisis and migration of population.

METHODS

We analyzed all reported active tuberculosis cases in a 15-year period, especially among patients aged > or =65, according to the Annual Reports of the Institute of Lung Diseases and Tuberculosis in Belgrade and Central Tuberculosis Register. Population estimates with extrapolations were based on 1991 and 2002 census data.

RESULTS

Total tuberculosis incidence rates showed a slight but non-significant decreasing trend (P=0.535), and no significant increase was found in patients aged > or =65 years (P=0.064), with an average age-specific incidence rate for the elderly of 64.0 (95% confidence interval, 60.7-67.4). The increase was significant in patients aged > or =70 years (y=49.3549+2.1186x; P=0.001), both in men (y=62.8666+2.3977x; P=0.005) and even more prominently in women (y=39.8240+1.9150x; P<0.001). The proportion of tuberculosis cases in the elderly peaked in 2005, with 35% of all tuberculosis cases.

CONCLUSION

High incidence rates and increasing time trend of tuberculosis in the elderly in Central Serbia is a serious problem, especially among those aged 70 years and over, who might present a target group for active case-finding of the disease.

Measuring burden of disease in two inner London boroughs using Disability Adjusted Life Years

BACKGROUND

This paper uses the Disability Adjusted Life Year (DALY) to estimate disease burden at a local level and relates this to programme budget (PB) data.

METHODS

We estimated DALY using the global burden of disease (GBD) template. For years of life lost, local mortality data were used and for years of life with disability, the GBD estimates from World Health Organization EURO A region (including the UK) were used. We used PB data to analyse how healthcare expenditure matched disease burden.

RESULTS

In 2005 the burden of disease in Lambeth was estimated at 36,368 DALYs (13,515 DALYs lost per 100,000) and in Southwark was 34,196 DALYs (13,244 DALYs lost per 100,000). There were gender and area differences. The ranking is different when mortality and morbidity are combined compared with mortality alone. We estimated that the average spend per DALY lost in 2005 was 11,066 pounds in Lambeth and 9390 pounds in Southwark.

CONCLUSIONS

We used a pragmatic approach to estimate overall disease burden providing a local, more comprehensive picture with important differences in spend by disease and health authority area. However, a more detailed approach to support decisions about prioritization based on modelling interventions that impact on avoidable burden of disease is recommended.
