Tuberculosis prevention in low- and middle-income settings in the Asia-Pacific region, a qualitative scoping review
Tuberculosis (TB) is a leading cause of death globally, with most new TB cases notified in the Asia-Pacific region. We aimed to synthesize qualitative research of TB prevention strategies from the region, summarizing reported barriers to and facilitators of practices, and identifying important gaps and opportunities for future research. A scoping review was conducted using the Arksey and O'Malley framework and includes qualitative studies publish…
Facemask and respirator use for bushfire smoke protection
BACKGROUND: As climate change intensifies the frequency and severity of bushfires, exposure to bushfire smoke is emerging as a significant public health concern, associated with numerous adverse health outcomes, including exacerbation of chronic obstructive pulmonary disease, asthma, cardiovascular diseases, and respiratory infections. OBJECTIVE: This study examined policies related to the use of masks and respirators as protective measures again…
Potential impact, costs, and benefits of population-wide screening interventions for tuberculosis in Viet Nam
Population-wide screening may accelerate the decline of tuberculosis (TB) incidence, but the optimal screening algorithm and duration must weigh resource considerations. We calibrated a deterministic transmission model to TB epidemiology in Viet Nam. We simulated three population-wide screening algorithms from 2025: sputum nucleic acid amplification tests (NAAT, Xpert MTB/RIF Ultra) only; chest radiography (CXR) followed by NAAT; and CXR-only wit…
Respiratory risks from wildfire-specific PM2.5 across multiple countries and territories
Under a warming climate, wildfires are becoming more frequent and severe. Multicountry studies evaluating associations between wildfire fine particulate matter (PM 2.5 ) and respiratory hospitalizations are lacking. Here we evaluate the short-term effects of wildfire-specific PM 2.5 on respiratory hospitalizations from 1,052 communities across Australia, Brazil, Canada, Chile, New Zealand, Vietnam, Thailand and Taiwan, during 2000–2019. A 1 μg m …
Health risks of exposure to wildfire-toxic air
Tuberculosis treatment and undernutrition on Daru Island, Papua New Guinea
A substantial proportion of people with tuberculosis (TB)-one of the world's deadliest infectious diseases-live in resource-poor, food insecure settings. It is widely recognised that undernutrition significantly heightens vulnerability to TB, as well as contributes to poor treatment adherence and outcomes. However, more attention is needed to understand what shapes food insecurity and undernutrition in a particular setting. We use the concept of …
The role and value of counsellors in the treatment journeys of people with tuberculosis and their families
Combined education and counselling can contribute to person-centred care for tuberculosis (TB), improving uptake, adherence, and outcomes of treatment for TB disease and TB infection. Though strongly recommended by the World Health Organization for all people diagnosed with TB, education and counselling is not widely implemented in TB programs around the world. In 2016, a pilot TB education and counselling program, delivered by trained profession…
Division on the Christian right
Polarization in American politics has not produced unity among conservative Christians. Drawing from original survey and interview data on Republican pastors in North Carolina, this paper seeks to understand why these pastors are divided on the legitimacy of force defending the “traditional American way of life.” We find (1) that theological fundamentalism has a positive, though weak, influence; (2) Christian nationalism and White grievance are p…
Beyond patient delay, navigating structural health system barriers to timely care and treatment in a high burden TB setting in Papua New Guinea
Tuberculosis (TB) is a major public health issue in Papua New Guinea, with incidence rates particularly high in the South Fly District of Western Province. We present three case studies, along with additional vignettes, that were derived from interviews and focus groups carried out between July 2019 and July 2020 of people living in rural areas of the remote South Fly District depicting their challenges accessing timely TB diagnosis and care; mos…
Exploring the use of masks for protection against the effects of wildfire smoke among people with preexisting respiratory conditions
Whilst COVID-19 has changed the nature of community mask use over the last couple of years, there is no guarantee that this event will influence an individual's mask behavior during other events like bushfires. Instead, we must create social support processes for early and appropriate mask use, including the use of air quality monitoring
Smoking behaviour, tobacco sales and tobacco advertising at 40 ‘Smoke Free Hospitals’ in Vietnam
Implementation of current smoke-free hospital regulations remains incomplete, with widespread evidence of smoking observed at three levels of the Vietnamese healthcare facilities. Further interventions are required to establish the reputation of Vietnamese healthcare facilities as smoke-free environments
Mortality benefits of reduction fine particulate matter in Vietnam, 2019
Introduction and objectives Studies assessing the health benefits of air pollution reduction in Vietnam are scarce. This study quantified the annual mortality burden due to PM 2.5 pollution in Vietnam above the World Health Organization recommendation for community health (AQG: 5 μg/m 3 ) and the proposed National Technical Regulation on Ambient Air Quality ( proposed QCVN: 15 μg/m 3 ). Methodology This study applied a health impact assessment me…
The Indoor Environment and Otitis Media among Australian Children
The association between the indoor environment and lifetime prevalence of otitis media (OM) in Australian children was assessed. We analysed data from a cross-sectional study of children, aged 7-11 years, performed in twelve Australian cities during 2007-2008. The main outcome was a parental report of their child's diagnosis with OM by a doctor. Information on the indoor environment (energy sources used for heating, cooling, and cooking, pets, an…

Exploring Tuberculosis Riskscapes in a Papua New Guinean 'Hotspot
This article explores socio-spatial dimensions of risk and how they can enhance understanding of a high burden tuberculosis (TB) context in the South Fly District of Papua New Guinea. We report on select findings from a qualitative study that included 128 semi-structured in-depth interviews and 10 focus group discussions with a wide range of South Fly District community members. Using the conceptual framework of 'riskscapes' to examine emic persp…
Standardised patient study to assess tuberculosis case detection within the private pharmacy sector in Vietnam
BACKGROUND: Of the estimated 10 million people affected by (TB) each year, one-third are never diagnosed. Delayed case detection within the private healthcare sector has been identified as a particular problem in some settings, leading to considerable morbidity, mortality and community transmission. Using unannounced standardised patient (SP) visits to the pharmacies, we aimed to evaluate the performance of private pharmacies in the detection and…
Development and Validation of a Sub-National, Satellite-Based Land-Use Regression Model for Annual Nitrogen Dioxide Concentrations in North-Western China
Existing national- or continental-scale models of nitrogen dioxide (NO 2 ) exposure have a limited capacity to capture subnational spatial variability in sparsely-populated parts of the world where NO 2 sources may vary. To test and validate our approach, we developed a land-use regression (LUR) model for NO 2 for Ningxia Hui Autonomous Region (NHAR) and surrounding areas, a small rural province in north-western China. Using hourly NO 2 measureme…
Sero-Prevalence of Sars-CoV-2 Antibodies in High-Risk Populations in Vietnam
As a response to the coronavirus disease 2019 (COVID-19) pandemic, Vietnam enforced strict quarantine, contact tracing and physical distancing policies resulting in one of the lowest numbers of individuals infected with severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) globally. This study aimed to determine the prevalence of SARS-CoV-2 antibody positivity among high-risk populations in Vietnam. A prevalence survey was undertaken withi…
Factors affecting healthcare pathways for chronic lung disease management in Vietnam
The study demonstrated the need for improved access to timely diagnosis and treatment of chronic lung disease within the lower level of the health system. This can be achieved by enhancing the communication skills and diagnostic capacity of local healthcare workers. Health education programmes for patients and caregivers will contribute to improved control of lung disease
Smoking behaviour among adult patients presenting to health facilities in four provinces of Vietnam
Smoking is common among male patients presenting to healthcare facilities in Vietnam. Formal smoking cessation supports are generally not used or offered. This population is likely to benefit from routine smoking cessation interventions that are integrated within the routine healthcare delivery system
How can airborne transmission of Covid-19 indoors be minimised?
During the rapid rise in COVID-19 illnesses and deaths globally, and notwithstanding recommended precautions, questions are voiced about routes of transmission for this pandemic disease. Inhaling small airborne droplets is probable as a third route of infection, in addition to more widely recognized transmission via larger respiratory droplets and direct contact with infected people or contaminated surfaces. While uncertainties remain regarding t…
Validation of the inhaler adherence questionnaire
The modified 4-item IAQ is simple, quick to complete and useful for measuring adherence with prescribed daily inhaled medication. This validation of the IAQ provides evidence for its utility in research and it will be important to validate this simple, inexpensive tool for use in clinical practice
Essential Medicines at the National Level
Patients with asthma need uninterrupted supplies of affordable, quality-assured essential medicines. However, access in many low- and middle-income countries (LMICs) is limited. The World Health Organization (WHO) Non-Communicable Disease (NCD) Global Action Plan 2013−2020 sets an 80% target for essential NCD medicines' availability. Poor access is partly due to medicines not being included on the national Essential Medicines Lists (EML) and/or N…
Characteristics in Stages of Change and Decisional Balance among Smokers
Smoking cessation remains a health promotion target. Applying the Transtheoretical Model to Australian Burden of Obstructive Lung Diseases (BOLD) data, we examined differences in stages of change (SoC) and readiness to quit decisional behaviours. Factors were identified likely to influence readiness of smokers, ≥40 years old, to quit. Analysis was restricted to current smokers classified to one of three stages: pre-contemplation (PC), contemplati…
Global, regional, and national age-sex-specific mortality for 282 causes of death in 195 countries and territories, 1980–2017
BACKGROUND: Global development goals increasingly rely on country-specific estimates for benchmarking a nation's progress. To meet this need, the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016 estimated global, regional, national, and, for selected locations, subnational cause-specific mortality beginning in the year 1980. Here we report an update to that study, making use of newly available data and improved methods. GBD …
Role of health locus of control beliefs and expectations of treatment efficacy in adjustment to cancer
We examined the effects of health locus of control beliefs (self-, doctor, and chance control) and expectations of treatment efficacy on short-term psychological adjustment in a sample of newly diagnosed cancer patients. The role of these beliefs and expectations in moderating the relation between (perceived and actual) disease severity and depression was also examined. The data were collected within one week of diagnosis. The relation between pe…

It Didn't Happen Here
This book purports to explain why socialism failed in the United States, but the ominoussounding It in the title is not organized socialism at all. Rather, Seymour Martin Lipset and Gary Marks are after even bigger game. Their target is not just the Socialist party, once led by Eugene Debs and Norman Thomas, but the whole idea of social solidarity and of politics as something that reflects more than a distinctly American “exceptional” set of cult…
Effectiveness of Postmigration Screening in Controlling Tuberculosis Among Refugees
Objectives. This study assessed the effectiveness of postmigration screening for the control of tuberculosis (TB) among refugee migrants. Methods. We conducted a historical cohort study among 24 610 predominantly Southeast Asian refugees who had arrived in Sydney, Australia, between 1984 and 1994. All had been screened for TB before arrival and had radiologic follow-up for 18 months after arrival. Incident cases of TB were identified by record li…

Is acculturation associated with sexual risk behaviours? An investigation of HIV-positive Latino men and women
This cross-sectional study of 226 HIV-positive Latino men and women sampled and assessed at an outpatient HIV clinic in Los Angeles examined the associations among acculturation, use of a substance before sex, and unsafe sexual behaviour. As acculturation increased, men and women were increasingly likely to have engaged in unsafe sex in the most recent sexual encounter since testing seropositive. In men, the association was partially mediated by …

Towards an understanding of sexual risk behavior in people living with HIV
Introduction HIV continues to spread through sexual transmission in the United States and elsewhere [1]. One source of transmission is unsafe sex among people who know they are infected with HIV. Of the estimated 800 000–900 000 people living with HIV in the United States [2], about two-thirds are aware of their seropositive status [3] and over 70% are sexually active after they learn they are infected [4–8]. Many engage in safer-sex practices; h…

Serostatus disclosure, sexual communication and safer sex in HIV-positive men
This study assessed HIV-positive men's sexual behaviours with partners at risk for infection, and examined the extent to which safer sex was associated with interpersonal communication variables, namely, (1). disclosure of one's seropositive status and (2). specific communication with partners about safer-sex practices. A total of 105 HIV-positive men (43% homosexual, 38% bisexual, 19% heterosexual), randomly sampled at an HIV outpatient clinic i…
Communist party membership in five former Soviet bloc countries, 1945?1989
This study examines the social composition of the communist party in the Soviet Union and four East European countries during the post-war period. Two alternative explanations for joining the communist party are examined: the classical political participation model from Western political science and the party policy model. In Western countries, the people who join political parties tend to be male, older, married, highly educated and in higher st…
Communication of HIV viral load to guide sexual risk decisions with serodiscordant partners among San Francisco men who have sex with men
The objective of this study was to estimate frequency and correlates of discussing HIV viral load (VL) with serodiscordant sex partners to guide decisions about sexual activities among men who have sex with men (MSM). We conducted a cross-sectional survey of 573 San Francisco MSM. Among 507 who knew their HIV status, 397 (78%) were familiar with the term 'viral load', and half (n=199) had a serodiscordant partner in the prior year. These 199 resp…
Factors associated with use of HIV primary care among persons recently diagnosed with HIV
The delay between testing positive for human immunodeficiency virus (HIV) and entering medical care can be better understood by identifying variables associated with use of HIV primary care among persons recently diagnosed with the virus. We report findings from 270 HIV-positive persons enrolled in the Antiretroviral Treatment Access Study (ARTAS). 74% had not seen an HIV care provider before enrollment; 26% had one prior visit only. Based on And…

Ultrafine Particles from Traffic Emissions and Children’s Health (Uptech) in Brisbane, Queensland (Australia)
Ultrafine particles are particles that are less than 0.1 micrometres (μm) in diameter. Due to their very small size they can penetrate deep into the lungs, and potentially cause more damage than larger particles. The Ultrafine Particles from Traffic Emissions and Children's Health (UPTECH) study is the first Australian epidemiological study to assess the health effects of ultrafine particles on children's health in general and peripheral airways …
Measuring progress and projecting attainment on the basis of past trends of the health-related Sustainable Development Goals in 188 countries
BACKGROUND: The UN's Sustainable Development Goals (SDGs) are grounded in the global ambition of "leaving no one behind". Understanding today's gains and gaps for the health-related SDGs is essential for decision makers as they aim to improve the health of populations. As part of the Global Burden of Diseases, Injuries, and Risk Factors Study 2016 (GBD 2016), we measured 37 of the 50 health-related SDG indicators over the period 1990-2016 for 188…
Healthcare Access and Quality Index based on mortality from causes amenable to personal health care in 195 countries and territories, 1990–2015
BACKGROUND: National levels of personal health-care access and quality can be approximated by measuring mortality rates from causes that should not be fatal in the presence of effective medical care (ie, amenable mortality). Previous analyses of mortality amenable to health care only focused on high-income countries and faced several methodological challenges. In the present analysis, we use the highly standardised cause of death and risk factor …
Global, regional, and national under-5 mortality, adult mortality, age-specific mortality, and life expectancy, 1970–2016
BACKGROUND: Detailed assessments of mortality patterns, particularly age-specific mortality, represent a crucial input that enables health systems to target interventions to specific populations. Understanding how all-cause mortality has changed with respect to development status can identify exemplars for best practice. To accomplish this, the Global Burden of Diseases, Injuries, and Risk Factors Study 2016 (GBD 2016) estimated age-specific and …
