In 2007, Nigeria commenced a nationwide behavioural change communication (BCC) intervention to increase uptake of tuberculosis (TB) care services. The purpose of this paper is to evaluate the effect of TB BCC intervention on knowledge and perception of TB in Enugu state, southeast Nigeria.

This is a cross-sectional study carried out in December 2009 in which a total of 1,200 respondents (620 males and 580 females) from six local government areas (three urban and three rural), selected by multi-stage sampling technique were interviewed using a semi-structured questionnaire.

The survey showed that most of the respondents had access to radio and about half to television. Access to media was significantly higher in urban areas than rural areas. Radio and community were the commonest sources of information of TB. The majority of the respondents were aware of that there was a message, however, ability to recall the content of the message varied. Significant association was observed between knowledge of the health education message and knowledge of TB transmission, that TB is curable and of appropriate care-seeking behaviour. Access to this media health education intervention was determined by age, gender, educational status, literacy, religion and access to media.

The study showed that TB BCC is associated with high-level awareness of TB disease and appropriate care-seeking behaviour. Socio-demographic characteristics and locality were found to influence access to mass media communication. Therefore, consideration should be given to the appropriateness of medium of communication in the design of TB BCC. However, there is need to combine it with other strategies to reach the disadvantaged population.

This study is the first population-based survey to ascertain access to TB-related BCC intervention and its effect on knowledge and care-seeking behaviour of this study population.

The purpose of this paper is to study the efficacy of a district tuberculosis (TB) co-ordinating team on health service performance for suspected TB patients in a district hospital in northeastern Thailand.

A comparison study of pre- and post-evaluations of TB system improvement was conducted in a district hospital in northeastern Thailand between October 2016 and June 2017. Data collection reviewed the record of suspected TB cases reported in the district hospital in the past nine months as a base line for describing the health service performance in term of received investigation for TB diagnosis. Participants from a TB clinic, district health office and health center set up a TB co-ordinating team to explore situations and systematic gaps. The TB co-ordinating team gave recommendations of health service performance for suspected TB patients over a nine-month period. Records of suspected TB cases health service performance were collected nine months after intervention. Data analysis by descriptive statistics and to test the effect of intervention was performed.

The records from 324 and 379 suspected TB cases reported in the hospital from the 9 months preceding and 9 months, respectively, after intervention were reviewed. A TB co-ordinating team was set up to improve the system and health service performance in terms of investigation for TB diagnosis. The results revealed that health service performance in terms of complete microscopy and investigation in both chest radiography and microscopy increased after intervention. When comparing between pre- and post-intervention, suspected cases received both chest radiography and microscopy in 176 cases and 283 cases, respectively (p-value=0.001). There were 27 cases diagnosed for smear positive TB in pre-intervention and 51 cases diagnosed in post-intervention (p-value=0.011). There were 21 cases pre- and 36 cases post-intervention that had referral documents from health center with no statistically significant difference.

The TB co-ordinating team had the role to improve health service performance for suspected TB cases to enroll in investigation process for increase TB diagnosis in district hospital.

The purpose of the paper is to show that, despite comprehensive coverage of services for TB provided by a public‐private partnership for TB control in Patan, a city in Nepal, case finding is low, compared with the target based on an Annual Risk of Tuberculosis Infection (ARTI) of 4 per cent. Doubts have been raised as to the appropriateness of the target. The objective of the study was to estimate the number of new TB cases occurring in Patan, to assess whether the target was appropriate.

In the paper doorstep interviews were conducted with all households in the study area, followed by in‐depth interviews of households with possible or probable TB cases. The survey findings were validated against the patient registers of the five DOTS centres in Patan.

The paper finds that, among the study population of 36,918, the household survey identified 17 smear‐positive TB cases (none privately‐treated) and 24 smear‐negative/extra‐pulmonary cases (including four privately‐treated cases). Validation against the DOTS patient registers indicated that the survey was 54 per cent complete. After adjusting for incompleteness, the number of smear‐positive cases in the study area was estimated as 31, equivalent to an incidence of 85 smear positives per 100,000 population and an ARTI of 1.7 per cent.

The paper shows that using the ARTI may lead to misleadingly high targets for urban TB control. Unrealistically high targets may cause TB workers to become demoralised, and useful strategies to be abandoned. Therefore, further work is needed to identify better ways of setting targets.

The purpose of the present work is to study the impacts of rapid cooling and Tb rare-earth additions on the structural, thermal and mechanical behavior of Bi–0.5Ag lead-free solder for high-temperature applications.

Effect of rapid solidification processing on structural, thermal and mechanical properties of Bi-Ag lead-free solder reinforced Tb rare-earth element.

The obtained results indicated that the microstructure consists of rhombohedral Bi-rich phase and Ag99.5Bi0.5 intermetallic compound (IMC). The addition of Tb could effectively reduce the onset and melting point. The elastic modulus of Tb-containing solders was enhanced to about 90% at 0.5 Tb. The higher elastic modulus may be attributed to solid solution strengthening effect, solubility extension, microstructure refinement and precipitation hardening of uniform distribution Ag99.5Bi0.5 IMC particles which can reasonably modify the microstructure, as well as inhibit the segregation and hinder the motion of dislocations.

It is recommended that the lead-free Bi-0.5Ag-0.5Tb solder be a candidate instead of common solder alloy (Sn-37Pb) for high temperature and high performance applications.

This study aims to assess the nexus among oil price (OP), renewable energy consumption (REC) and trade balance (TB) for India using annual time series data for the time period 1985–2019. In particular, the authors examine whether REC improves India's TB in the context of high oil import dependence.

The study uses autoregressive distributed lags (ARDL) bound testing approach that has the advantage of yielding estimates of long-run and short-run parameters simultaneously. Moreover, the small sample properties of this approach are superior to other multivariate cointegration techniques. Fully modified ordinary least square (FMOLS) and dynamic ordinary least squares (DOLS) are also applied to test the robustness of the results. The causality among the series is investigated through block exogeneity test based on vector error correction model.

The findings based on ARDL bounds testing approach indicate that OPs exert a negative impact on TB of India in both long run and short run, whereas REC has a favorable impact on the TB. In particular, 1% increase in OPs decreases TBs by 0.003% and a 1% increase in REC improves TB by 0.011%. The results of FMOLS and DOLS corroborate the findings from ARDL estimates. The results of block exogeneity test suggest unidirectional causation from OPs to TB; OPs to REC and REC to TB.

The study underscore the importance of renewable energy as a potential tool to curtail trade deficits in the context of Indian economy. Our results suggest that the policymakers must pay attention to the hindrances in augmentation of renewable energy usage and try to capitalize on the resulting gains for the TB.

Climate change is a major challenge for developing countries like India. Renewable energy sector is considered an important instrument toward attaining the twin objectives of environmental sustainability and employment generation. This study underscores another role of REC as a tool to achieve a sustainable trade position, which may help India save her valuable forex reserves for broader objectives of economic development.

To the best of the authors’ knowledge, this is the first study that probes the dynamic nexus among OPs, REC and TB in Indian context. From a policy standpoint, the study underscores the importance of renewable energy as a potential tool to curtail trade deficits in context of India. From a theoretical perspective, the study extends the literature on the determinants of TB by identifying the role of REC in shaping TB.

Some African policymakers have turned their attention towards electronic transaction levy (e-levy) to maximise tax revenues in recent years due to the inability to meet revenue targets. However, some argue that the implementation of an e-levy will increase the tax burden (TB) and the currency outside banks (COB). Primarily, this paper examined the effects of the TB and COB on economic development as well as the impact of institutional quality on moderating the nexus.

This paper used structural equation modelling (SEM) and maximum likelihood (ML) estimation techniques on quarterised data from 1996 to 2020.

The results show that the TB negatively impacts gross domestic product (GDP) per capita and urbanisation but positively affects the Economic Freedom of the World Index (EFWI). The COB impacts EFWI, GDP per capita and urbanisation positively. Institutional quality moderates the TB and the COB, establishing positive relationships with the economic development indicators.

The findings strongly imply that the arguments that TB and COB are catalysts for tax evasion and corruption lack substantial empirical evidence.

The examination of the econometric impact of the COB on economic development is one of the first studies in the field. The paper recommends that to drive economic development and accelerate sustainable development goals (SDGs) achievement, tax revenues should be channelled into the productive sectors of the Ghanaian economy.

Purpose – One-third of the world's population is infected with tuberculosis (TB) and there are two million TB-related deaths worldwide every year. Along the U.S.-Mexico border, migration patterns, and reduced access to health care contribute to high rates of TB. Delayed diagnosis of TB, the focus of this chapter, increases the likelihood that a patient will progress to more advanced stages of the disease and heightens the risk of TB transmission to others as patients are contagious for longer periods of time.

Approach – Despite the seriousness of these consequences, few sociological studies have examined delayed diagnosis of TB and why people affected by TB symptoms delay care. Because of this, we take a health narratives approach to understanding the experiences of 15 TB patients of Mexican descent in a high-risk border community (e.g., El Paso, Texas) in order to discover why delayed diagnoses happen and how they impact patients.

Findings – Fourteen of the fifteen patients experienced delayed diagnosis. Analysis of these fourteen narratives revealed two broad themes: (1) provider lack of awareness, including repeated misdiagnosis and TB test errors, and (2) patient disadvantage, including fear of U.S. immigration authorities and few economic resources for care.

Implications – Findings from this study suggest that prompt diagnosis of TB could be achieved if providers were more cognizant of TB and its symptoms and public health policies increased access to health care regardless of immigration status or socioeconomic status.

Motivated by recent rapid exchange rate depreciations, shrank economic growth, high inflation, and persistent trade deficits, this study examines the trade balance (TB) in the face of the recent dynamics of the stated macroeconomic factors, which are also important determinants of the TB. The symmetric test of the J-curve phenomenon for the selected Sub-Saharan African (SSA) countries is revisited in this regard. The study uses panel data from 1970 to 2020 for ten of these countries for the longitudinal panel analysis with the TB as the dependent variable and the real exchange rate, foreign and domestic national incomes, and trade openness as the set of independent variables.

Because the underlying data set involves a heterogeneous panel of relatively short N and long T, the pooled mean group (PMG) and mean group (MG) heterogeneous panel models are employed based on the Hausman test for parameter consistency in heterogeneous panels.

The findings largely support the domestic income growth– TB worsening and the foreign income growth– TB improvement hypotheses. Trade openness is found to mostly augment the TB performance of the countries. The results also validated the J-curve effect for only 3/10 and 2/10 countries in the PMG and MG models, respectively. The divergence for most of the countries is attributed to possible import compression and institutional structure of SSA countries.

Given the favorable effects of trade openness on the TB performance of SSA countries, it is recommended that SSA countries place much emphasis on import-substitution industrialization and value addition to their natural resources as well as investment-driven growth policies to improve the competitiveness of their exports and reverse the chronic deficits in their TBs.

This paper is unique for invoking heterogeneous panel models to analyze the TB in light of recent dynamics of its determinants, as well as providing an update on the symmetric test of the J-curve phenomenon for the selected SSA countries.

This intensified case finding study aimed to evaluate the prevalence of tuberculosis (TB) disease among people with HIV entering the largest prison in Malaysia.

The study was conducted in Kajang prison, starting in July 2013 in the men’s prison and June 2015 in the women’s prison. Individuals tested positive for HIV infection, during the mandatory HIV testing at the prison entry, were consecutively recruited over five months at each prison. Consented participants were interviewed using a structured questionnaire and asked to submit two sputum samples that were assessed using GeneXpert MTB/RIF (Xpert) and culture, irrespective of clinical presentation. Factors associated with active TB (defined as a positive result on either Xpert or culture) were assessed using regression analyses.

Overall, 214 incarcerated people with HIV were recruited. Most were men (84.6%), Malaysians (84.1%) and people who inject drugs (67.8%). The mean age was 37.5 (SD 8.2) years, and median CD4 lymphocyte count was 376 cells/mL (IQR 232–526). Overall, 27 (12.6%) TB cases were identified, which was independently associated with scores of five or more on the World Health Organization clinical scoring system for prisons (ARR 2.90 [95% CI 1.48–5.68]).

Limited data exists about the prevalence of TB disease at prison entry, globally and none from Malaysia. The reported high prevalence of TB disease in the study adds an important and highly needed information to design comprehensive TB control programmes in prisons.

The purpose of this paper is to analyze poor management of tuberculosis (TB) prevention and treatment and explore parameters and causes of this problem drawing on qualitative interviews with former prisoners and medical specialists in Kaliningrad Oblast in Russia.

The authors undertook a qualitative study, to explore access to HIV and TB treatment for people who inject drugs in Kaliningrad. The authors interviewed (outside of prisons) 15 patients and eight health specialists using a semi-structured guide. The authors analyzed the accounts thematically and health consequences of imprisonment emerged as a major theme.

Prisons are overcrowded and lack basic hygiene and infection control. Demand for medical services outstrip supply, HIV and TB prevention lacking, HIV and TB treatment is patchy, with no second-line drugs available for resistant forms. The prison conditions are generally degrading and unhealthy and many respondents perceived surviving prisons as a miracle. Cooperation with medical services in the community is poor.

The authors used qualitative research methods, which do not rely on a representative sample. However, many of the structural barriers preventing effective TB treatment and prevention highlighted in this paper have been noted elsewhere, suggesting that findings are likely to reflect conditions elsewhere in Russia. The authors tried to include all possible points of view, as of the medical staff and the patients. However, due to resistance of the officials the authors were unable to conduct interviews with employees of the FCS. Since all the interviews are recalling past experience, the situation may have changed. This does not undermine importance of the findings, as they shed light on particular treatment experiences, and development of prison health system.

The paper contributes to the literature on prisons as a contributor to TB epidemic, including drug resistant forms. An urgent penitentiary reform in Russia should focus on HIV and TB prevention, case detection, availability of medications and effective treatments. Key to decreasing prison population and improving health is political reform aimed at introduction of effective drug treatment, de-penalization and de-criminalization of drug users and application of alternatives to incarceration.
