Three classess of tests are now recommended in the latest consolidated guideles on tests for tuberculosis infection. It includes for the first-time a new class of Mycobacterium tuberculosis antigen-based skin tests (TBSTs), and the two existing classes of tests: the tuberculin skin test (TST) and t...he interferon-gamma release assays (IGRAs).
IGRAs and TBSTs use Mycobacterium tuberculosis complex specific antigens and represent a significant advancement to TST which has been used for over half a century.

.Chronic manifestations of Chagas disease present as disabling and life-threatening condi-tions affecting mainly the cardiovascular and gastrointestinal systems. Although meaningful research has outlined the different molecular mech...anisms underlying Trypanosoma cruzi’s infection and the host-parasite interactions that follow, prompt diagnosis and treatment remain a challenge, particu-larly in developing countries and also in those where the disease is considered non-endemic. This review intends to present an up-to-date review of the parasite’s life cycle, genetic diversity, virulence factors, and infective mechanisms, as well as the epidemiology, clinical presentation, diagnosis, and treatment options of the main chronic complications of Chagas disease.

The Practical manual on laboratory strengthening, 2022 update provides practical guidance on implementation of WHO recommendations and best practices for TB laboratory strengthening. It is an updated version of the GLI Practical Guide to Laboratory Strengthening published in 2017 and provides the la...test practical guidance on use of newly recommended diagnostics as well as guidance in key technical areas, including quality assurance and quality management systems, specimen collection and registration, procurement and supply-chain management, diagnostic connectivity, biosafety, data management, human resources, strategic planning, and model algorithms. The key changes are:
inclusion of recent or updated WHO recommendations for tests to diagnose TB and detect drug resistance;
alignment with the latest WHO critical concentrations for phenotypic drug-susceptibility testing (DST) and the new definitions of pre-XDR-TB and XDR-TB;
updated information on building quality-assured TB testing and management capacity using the Stepwise Laboratory Quality Improvement Process Towards Accreditation (SLIPTA) approach (Score-TB package1);
updated information on assessing, analysing and optimising TB diagnostic networks; and
updated information on the use of next-generation sequencing (NGS) to detect mutations associated with drug resistance for surveillance purposes.
The document also provides references to resources and tools relevant for work on laboratory strengthening.

The World Health Organization (WHO) and the global community of countries, partners, donors, technical experts, scientists and field implementation teams continue to work towards the ultimate goal of a world free of the burden of neglected tropical diseases (NTDs).
Human African trypanosomiasis (HAT) has been an alarming global public health issue. The disease affects mainly poor and marginalized people in low-resource settings and is caused by two subspecies of haemoflagellate parasite, Trypanosoma brucei and transmitted by tsetse flies. Progress made in HAT ...control during the past decade has prompted increasing global dialogue on its elimination and eradication. The disease is targeted by the World Health Organization (WHO) for elimination as a public health problem by 2020 and to terminate its transmission globally by 2030, along-side other Neglected Tropical Diseases (NTD). Several methods have been used to control tsetse flies and the disease transmitted by them. Old and new tools to control the disease are available with constraints.
Currently, there are no vaccines available. Efforts towards intervention to control the disease over the past decade have seen considerable progress and remarkable success with incidence dropping progressively, reversing the upward trend of reported cases. This gives credence in a real progress in its elimination. This study reviews various control measures, progress and a highlight of control issues, vector and parasite barriers that may have been hindering progress towards its elimination.

The majority of developing countries will fail to achieve their targets for Universal Health Coverage (UHC)1 and the health- and poverty-related Sustainable Development Goals (SDGs) unless they take urgent steps to strengthen their health financing. Just over a decade out from the SDG deadline of 20...30, 3.6 billion people do not receive the most essential health services they need, and 100 million are pushed into poverty from paying out-of-pocket for health services. The evidence is strong that progress towards UHC, core to SDG 3, will spur inclusive and sustainable economic growth, yet this will not happen unless countries achieve high-performance health financing, defined here as funding levels that are adequate and sustainable; pooling that is sufficient to spread the financial risks of ill-health; and spending that is efficient and equitable to assure desired levels of health service coverage, quality, and financial protection for all people— with resilience and sustainability.

Cardiovascular diseases (CVDs) have collectively remained the leading causes of death worldwide and substantially contribute to loss of health and excess health system costs. The Global Burden of Diseases, Injuries, and Risk Factors (GBD) Study has tracked trends in death and disability since 1990 a...nd has provided an updated perspective on the status of cardiovascular health globally, regionally, and nationally.

The Public Health Burden of Commercial Tobacco Use
The burden of disease and death from commercial tobacco* use in the United States is
overwhelmingly caused by cigarettes and other combustible tobacco products.
Noncommunicable diseases (NCDs) – chief among them, cardiovascular diseases (heart disease and stroke), cancer, diabetes and chronic respiratory diseases – along with mental health, cause nearly three quarters of deaths in the world. Their drivers are social, environmental, commercial and geneti...c, and their presence is global. Every year 17 million people under the age of 70 die of NCDs, and 86% of them live in low- and middle-income countries (LMICs).

Background
Asthma education, a key component of long-term asthma management, is challenging in resource-limited settings with shortages of clinical staff. Task-shifting educational roles to lay (non-clinical) staff is a potential solution. We conducted a randomised controlled trial of an enhanced a...sthma care intervention for children in Malawi, which included reallocation of asthma education tasks to lay-educators. In this qualitative sub-study, we explored the experiences of asthmatic children, their families and lay-educators, to assess the acceptability, facilitators and barriers, and perceived value of the task-shifting asthma education intervention.
Methods
We conducted six focus group discussions, including 15 children and 28 carers, and individual interviews with four lay-educators and a senior nurse. Translated transcripts were coded independently by three researchers and key themes identified.
Results
Prior to the intervention, participants reported challenges in asthma care including the busy and sometimes hostile clinical environment, lack of access to information and the erratic supply of medication. The education sessions were well received: participants reported greater understanding of asthma and their treatment and confidence to manage symptoms. The lay-educators appreciated pre-intervention training, written guidelines, and access to clinical support. Low education levels among carers presented challenges, requiring an open, non-critical and individualised approach.
Discussion
Asthma education can be successfully delivered by lay-educators with adequate training, supervision and support, with benefits to the patients, their families and the community. Wider implementation could help address human resource shortages and support progress towards Universal Health Coverage.

Asthma is the most common noncommunicable disease in children, and among the most common in adults. According to the most recent estimates from the Global Asthma Network Phase I study, around one in 10 children and adults have symptoms of asthma and one in 20 school-aged children have severe asthma ...symptoms, with marked variations in prevalence and in prevalence trends between countries and regions of the world. The Global Burden of Disease Study estimated that asthma caused the loss of 21.6 million healthy years of life (disability-adjusted life years) and 461 069 deaths in 2019. Approximately 90% of the asthma burden of disease is borne by people living low and middle income countries (LMICs). Some countries report very high (up to 90%) rates of uncontrolled asthma. While the prevalence of asthma is highest in countries with a high Socio-Demographic Index (SDI), death rates from asthma are highest in countries with low and lower middle incomes.

Cystic fibrosis (CF) was earlier thought to be a disease prevalent in the West among Caucasians. However, quite a number of recent studies have uncovered CF cases outside of this region, and reported hundreds of unique and novel variant forms of CFTR. Here, we discuss the evidence of CF in parts of... the world earlier considered to be rare; Africa, and Asia. This review also highlighted the CFTR mutation variations and new mutations discovered in these regions. This discovery implies that the CF data from these regions were earlier underestimated. The inadequate awareness of the disease in these regions might have contributed towards the poor diagnostic facilities, under-diagnosis or/and under-reporting, and the lack of CF associated health policies. Overall, these regions have a high rate of infant, childhood and early adulthood mortality due to CF. Therefore, there is a need for a thorough investigation of CF prevalence and to identify unique and novel variant mutations within these regions in order to formulate intervention plans, create awareness, develop mutation specific screening kits and therapies to keep CF mortality at bay.

Addressing comorbidities and risk factors for tuberculosis (TB) is a crucial component of the World Health Organization (WHO)’s End TB Strategy. This WHO operational handbook on tuberculosis. Module 6: tuberculosis and comorbidities aims to support countries in scaling up people-centred care, base...d on the latest WHO recommendations on TB and key comorbidities, and drawing upon additional evidence, best practices and inputs from various experts and stakeholders obtained during WHO processes. It is intended for use by people working in ministries of health, particularly TB programmes and the relevant departments or programmes responsible for comorbidities and health-related risk factors for TB such as HIV, diabetes, undernutrition, substance use, and tobacco use, as well as programmes addressing mental health and lung health. This operational handbook is a living document and will include a separate section for each of the key TB comorbidities or health-related risk factors. The third edition includes guidance for HIV-associated TB, mental health conditions and diabetes, which are three conditions strongly associated with TB and which result in higher mortality, poorer TB treatment outcomes and negatively impact health-related quality of life. The operational handbook aims to facilitate early detection, proper assessment and adequate management of people affected by TB and comorbidities. Full implementation of this guidance is expected to have a significant impact on TB treatment outcomes and health-related quality of life for people affected by TB.

Frontline health workers (FHWs) provide services directly to communities where they are most needed, especially in remote and rural areas. Many are community health workers and midwives, though they can also include local emergency responders/paramedics, pharmacists, nurses, and doctors who serve in... community clinics.
The growing burden of non-communicable diseases (NCDs) on low- and middle-income countries threatens many health systems that are already weakened. In many countries, health systems—and health workers—are not prepared to address the complex nature of NCDs. Health systems are often fragmented, and designed to respond to single episodes of care or long-term prevention and control of infectious diseases.1 Many countries also continue to face shortages and distribution challenges of trained and supported health workers. As most NCDs are multifactorial in origin and are detected later in their evolution, health systems face significant challenges to provide early detection as well as affordable, effective, and timely treatment, particularly in underserved communities.
