Hepatitis B (HBV) infection is a major public health problem and cause of chronic liver disease.
The 2024 HBV guidelines provide updated evidence-informed recommendations on key priority topics. These include expanded and simplified treatment criteria for adults but now also for adolescents; expa...nded eligibility for antiviral prophylaxis for pregnant women to prevent mother-to-child transmission of HBV; improving HBV diagnostics through use of point-of-care HBV DNA viral load and reflex approaches to HBV DNA testing; who to test and how to test for HDV infection; and approaches to promote delivery of high-quality HBV services, including strategies to promote adherence to long-term antiviral therapy and retention in care.
The 2024 guidelines include 11 updated chapters with new recommendations and also update existing chapters without new recommendations, such as those on treatment monitoring and surveillance for liver cancer.

The World Heart Federation (WHF) Roadmap series covers a large range of cardiovascular conditions. These Roadmaps identify potential roadblocks and their solutions to improve the prevention, detection and management of cardiovascular diseases and provide a generic global framework available for loca...l adaptation. A first Roadmap on raised blood pressure was published in 2015. Since then, advances in hypertension have included the publication of new clinical guidelines (AHA/ACC; ESC; ESH/ISH); the launch of the WHO Global HEARTS Initiative in 2016 and the associated Resolve to Save Lives (RTSL) initiative in 2017; the inclusion of single-pill combinations on the WHO Essential
Medicines’ list as well as various advances in technology, in particular telemedicine and mobile health. Given the substantial benefit accrued from effective interventions in the management of hypertension and their potential for scalability in low and middle-income countries (LMICs), the WHF has now revisited and updated the ‘Roadmap for raised BP’ as ‘Roadmap for hypertension’
by incorporating new developments in science and policy. Even though cost-effective lifestyle and medical interventions to prevent and manage hypertension exist, uptake is still low, particularly in resource-poor areas. This Roadmap examined the roadblocks pertaining to both the demand side (demographic and socio-economic factors, knowledge and beliefs, social relations, norms, and
traditions) and the supply side (health systems resources and processes) along the patient pathway to propose a range of possible solutions to overcoming them. Those include the development of population-wide prevention and control programmes; the implementation of opportunistic screening and of out-of-office blood pressure measurements; the strengthening of primary care and a greater focus on task sharing and team-based care; the delivery of people-centred care and stronger patient and carer education; and the facilitation of adherence to treatment. All of the above are dependent upon the availability and effective distribution of good quality, evidencebased, inexpensive BP-lowering agents.

Asbestos, the most frequent cause of occupational cancer, continues to be consumed ona massive scale, with millions of people exposed on a daily basis. This review explains why we havefailed in curtailing the silent epidemic of asbestos-related disease and why the numbers of asbestosvictims are like...ly to remain high. Emerging and developed countries have to be reminded that asbestosexposure has yet to become a problem of the past. The worldwide spread of asbestos, followed by thesurge of asbestos-related cancers, resembles the lung cancer epidemic caused by smoking andstimulated by manufacturers.

Background
Low- and middle-income countries now experience the highest prevalence and mortality rates of cardiovascular disease.
Main text
While improving the availability and delivery of proven, effective therapies will no doubt mitigate this burden, we posit that studies evaluating cardiovasc...ular disease risk factors, management strategies and service delivery, in diverse settings and diverse populations, are equally critical to improving outcomes in low- and middle-income countries. Focusing on examples drawn from four cardiovascular diseases — coronary artery disease, stroke, diabetes and kidney disease — we argue that ethnicity, culture and context matter in determining the risk factors for disease as well as the comparative effectiveness of medications and other interventions, particularly diet and lifestyle interventions.
Conclusion
We believe that a host of cohort studies and randomized control trials currently being conducted or planned in low- and middle-income countries, focusing on previously understudied race/ethnic groups, have the potential to increase knowledge about the cause(s) and management of cardiovascular diseases across the world.

Many low- and middle-income countries (LMICs) are undergoing an epidemiological transition. With an improvement in socioeconomic conditions and an aging population, cardiovascular diseases (CVDs), like cardiac arrhythmias, are expected to increase in these countries. However, there are limited studi...es on the epidemiology and management of cardiac arrhythmias in LMICs. This review will highlight the unique challenges and opportunities that these countries face when managing cardiac arrhythmias.

The Coronavirus Disease 2019 (COVID-19) has had a continuous and robust impact on world health. The resulting COVID-19 pandemic has had a devastating physical, mental and fiscal impact on the millions of people living with noncommunicable diseases (NCDs), as they have a higher risk of severe illness... and death from COVID-19. COVID-19 has been associated with an
excess in all-cause and cardiovascular disease (CVD) mortality beyond that related to the infection itself and its immediate consequences. Studies in the
United Kingdom (UK) and United States of America (USA) have clearly shown increasing deaths from ischemic heart disease, stroke and hypertensive disease due to COVID-19. Overall, the impact has been greater in individuals with lower socioeconomic status, even in high income nations.

ABSTRACT
More than 500 million people worldwide live with cardiovascular disease (CVD). Health systems today face fundamental challenges in delivering optimal care due to ageing populations, healthcare workforce constraints, financing, availability and affordability of CVD medicine, and service del...ivery.
Digital health technologies can help address these challenges. They may be a tool
to reach Sustainable Development Goal 3.4 and reduce premature mortality from
non-communicable diseases (NCDs) by a third by 2030. Yet, a range of fundamental barriers prevents implementation and access to such technologies. Health system governance, health provider, patient and technological factors can prevent or distort their implementation.
World Heart Federation (WHF) roadmaps aim to identify essential roadblocks on the pathway to effective prevention, detection, and treatment of CVD. Further, they aim to provide actionable solutions and implementation frameworks for local adaptation. This WHF Roadmap for digital health in cardiology identifies barriers to implementing digital health technologies for CVD and provides recommendations for overcoming them.

Background
Chronic congestive heart failure is a common condition that, if untreated, markedly impairs the quality of life and is associated with a high risk of recurrent hospitalization and death.
Methods
This review is based on articles retrieved by a selective search in PubMed, as well as on r...elevant guidelines.
Results
Evidence-based treatment options are available only for congestive heart failure with a low ejection fraction. Pharmacotherapy is based on neurohumoral inhibition of the renin-angiotensin-aldosterone system and the adrenergic system. The prognosis of patients with this condition has been further improved recently through the introduction of combined angiotensin receptor antagonists and neprilysin inhibitors. Modern implantable devices are a further component of treatment. Implantable defibrillators and special pacemakers for cardiac resynchronization are well established; the utility of alternative devices (baroreflex modulation or cardiac contractility modulation) needs to be investigated in further studies. It was recently shown that the catheter-based treatment of secondary mitral regurgitation with a MitraClip improves the outcome of selected patients.
Conclusion
The treatment of chronic systolic heart failure as recommended in the relevant guidelines, with drugs and implanted devices if indicated, can significantly improve the clinical outcome.

About one fourth of the world’s population is estimated to have been infected with the tuberculosis (TB) bacilli, and about 5–10% of those infected develop TB disease in their lifetime. The risk for TB disease after infection depends on several factors, the most important being the person’s im...munological status. TB preventive treatment (TPT) given to people at highest risk of progressing from TB infection to disease remains a critical element to achieve the global targets of the End TB Strategy, as reiterated by the second UN High Level Meeting on TB in 2023. Delivering TPT effectively and safely necessitates a programmatic approach to implement a comprehensive package of interventions along a cascade of care: identifying individuals at highest risk, screening for TB and ruling out TB disease, testing for TB infection, and choosing the preventive treatment option that is best suited to an individual, managing adverse events, supporting medication adherence and monitoring programmatic performance.

Under-diagnosis of asthma in ‘under-fives’ may be alleviated by improved inquiry into disease history. We assessed a questionnaire-based screening tool for asthma among 614 ‘under-fives’ with severe respiratory illness in Uganda. The questionnaire responses were compared to post hoc consensu...s diagnoses by three pediatricians who were guided by study definitions that were based on medical history, physical examination findings, laboratory and radiological tests, and response to bronchodilators. Children with asthma or bronchiolitis were categorized as “asthma syndrome”. Using this approach, 253 (41.2%) had asthma syndrome. History of and present breathing difficulties and present cough and wheezing was the best performing combination of four questionnaire items [sensitivity 80.8% (95% CI 77.6–84.0); specificity 84.7% (95% CI 81.8–87.6)]. The screening tool for asthma syndrome in ‘under-fives’ may provide a simple, cheap and quick method of identifying children with possible asthma. The validity and reliability of this tool in primary care settings should be tested.

Terminology used to describe the transmission of pathogens through the air varies across scientific disciplines, organizations and the general public. While this has been the case for decades, during the coronavirus disease (COVID-19) pandemic, the terms ‘airborne’, ‘airborne transmission’ a...nd ‘aerosol transmission’ were used in different ways by stakeholders in different scientific disciplines, which may have contributed to misleading information and confusion about how pathogens are transmitted in human populations.
This global technical consultation report brings together viewpoints from experts spanning a range of disciplines with the key objective of seeking consensus regarding the terminology used to describe the transmission of pathogens through the air that can potentially cause infection in humans.
This consultation aimed to identify terminology that could be understood and accepted by different technical disciplines. The agreed process was to develop a consensus document that could be endorsed by global agencies and entities. Despite the complex discussions and challenges, significant progress was made during the consultation process, particularly the consensus on a set of descriptors to describe how pathogens are transmitted through the air and the related modes of transmission. WHO recognizes the important areas where consensus was not achieved and will continue to address these areas in follow-up consultations.

Background: Mental health has recently gained increasing attention on global health and development agendas, including calls for an increase in international funding. Few studies have previously characterized official development assistance for mental health (DAMH) in a nuanced and differentiated ma...nner in order to support future funding efforts. Methods: Data from the Organisation for Economic Cooperation and Development Creditor Reporting System were obtained through keyword searches. Projects were manually reviewed and categorized into projects dedicated entirely to mental health and projects that mention mental health (as one of many aims). Analysis of donor, recipient, and sector characteristics within and between categories was undertaken cumulatively and yearly.

More than 40% of the world population is 24 years old or younger, the vast majority of whom live in low- and lower middle–income countries. Globally, a quarter of disability-adjusted life years (DALYs) for mental disorders and substance abuse is borne by this age group and about 75% of mental diso...rders diagnosed in adulthood have their onset before the age of
24 years . Most children and young people in developing countries, however, do not have access to mental health care.

People affected by impairments and disabilities associated with TB are even more likely to belong to marginalized segments of society and are more likely to have their human rights unprotected. The challenges faced by people affected by TB include the consequences of impairment and disability associ...ated with the disease, its treatment as well as with the stigma and discrimination applied to people affected by TB. There is now compelling evidence that the disease and its treatment affect quality of life and life expectancy even after successful treatment.
The WHO Global Tuberculosis Programme has produced the first policy brief on TB-associated disability, building on the increasing evidence in recent years on the unaddressed needs of people with TB who experience impairment and disability while on TB treatment and after completing TB treatment.

Access to safe blood and blood products is recognized as one of the key requirements for delivery of modern health care in the journey towards health for all. The foundation of safe and sustainable blood supplies depends on the collection of blood from voluntary non-remunerated and low-risk donors. ...Data from the WHO Global Database for Blood Safety (GDBS) brings out several inadequacies related to the supply and safety of blood and blood products. These inadequacies include a number of variations in safe blood practices across the world, including the quantity of blood donated (voluntary and replacement types), quality and adequate testing of the donated blood (immunohaematology [IH] and transfusion-transmitted infections [TTIs]), rational use of blood and blood components such as appropriate patient blood management protocols. These variations are very high in countries of the South-East Asian Region and most of them are either low- or middle-income countries (LMICs).

The environment in which young people live, learn and play significantly affects their decisions about whether to consume alcohol. Environmental factors are the main risk factors driving alcohol consumption and related harm among young people. Environments that normalize alcohol consumption – term...ed alcogenic environments – include contexts with unregulated advertising and marketing of alcoholic beverages, higher alcohol outlet density, products designed to facilitate affordability and low prices of alcoholic beverages. A recent body of research evidence has emerged related to the measurement, functional significance and consequences of living in alcogenic environments. This includes findings on the complex and bidirectional interactions among alcohol acceptability, availability and affordability and how they create and perpetuate alcogenic environments. Comprehensive and enforced alcohol control policies are effective at delaying the age of onset and lowering alcohol prevalence and frequency among young people. Evidence consistently confirms the effectiveness of designing and implementing alcohol control policies that regulate upstream the drivers of alcogenic environment, including alcohol availability, acceptability and affordability. These policies need to be multipronged and address the complex interactions between these drivers and the local alcohol culture

The Infection prevention and control in the context of coronavirus disease 2019 (COVID-19): a living guideline consolidates technical guidance developed and published during the COVID-19 pandemic into evidence-informed recommendations for infection prevention and control (IPC). This living guideline... is available both online and PDF.
**This version of the living guideline (version 5.0) **includes the following seven revised statements for the prevention, identification and management of SARS-CoV-2 infections among health and care workers:
a good practice statement on national and subnational testing strategies;
a good practice statement on passive syndromic surveillance of health and care workers;
a good practice statement on prioritizing health and care workers for SARS-CoV-2 testing;
a good practice statement on protocols for reporting and managing health and care worker exposures;
a good practice statement to limit in-person work of health and care workers with active SARS-CoV-2 infections;
a statement on high-risk exposures and quarantine; and,
a conditional recommendation on the duration of isolation for health and care workers.
Understanding the updated section
Prevention of infections in the health care setting includes a multi-pronged and multi-factorial approach that includes IPC and occupational health and safety measures and adherence to Public Health and Social Measures in the community by the health workforce. The underlying infection prevention and control strategy of this section is the notion that early identification of symptomatic cases, testing and quarantining/isolating health and care workers decreases the risk of nosocomial infection to patients and to other health and care workers.

Las olas de transmisión de la fiebre amarilla ocurridas en la Región de las Américas entre el 2016 y el 2018 causaron el mayor número de casos humanos y epizoóticos registrados en varios decenios. La fiebre amarilla es una enfermedad hemorrágica viral grave que representa un desafío para el p...rofesional de salud: exige el reconocimiento temprano de signos y síntomas muchas veces inespecíficos, que pueden parecerse a otros síndromes febriles agudos. La detección temprana de los casos sospechosos o confirmados, el monitoreo de los signos vitales y las medidas de soporte vital, y el tratamiento de la insuficiencia hepática aguda siguen siendo las estrategias recomendadas para el manejo de los casos. El presente informe es el resultado de las deliberaciones sobre la experiencia de expertos de la Región en cuanto al manejo clínico de pacientes con fiebre amarilla, especialmente en brotes y epidemias, mediante la contextualización de esa experiencia en el conjunto actual de la evidencia médico-científica y la consideración de las directrices técnicas ya disponibles en los países de la Región. Presenta flujogramas para la evaluación inicial del paciente con sospecha clínica de fiebre amarilla y sugiere un conjunto mínimo de pruebas de laboratorio que puede ser útil cuando hay pocos recursos; además, detalla aspectos de la organización de los sistemas de salud para enfrentar brotes y epidemias de fiebre amarilla.

The waves of yellow fever transmission in the Region of the Americas in 2016–2018 involved the largest number of human and epizootic cases to be reported in several decades. Yellow fever is a serious viral hemorrhagic disease that poses a challenge for health professionals. It requires early recog...nition of signs and symptoms, which are often nonspecific, and it can mimic other acute febrile syndromes. Early detection of suspected or confirmed cases, monitoring of vital signs, life support measures, and treatment of acute kidney failure continue to be the recommended strategies for case management. This report is the result of discussions among experienced specialists in the Americas on the clinical management of yellow fever patients, especially during outbreaks and epidemics, in the context of current medical and scientific evidence and taking into account the technical guidelines already available in the countries of the Region. It includes flowcharts for initially addressing patients with clinical suspicion of yellow fever and proposes a minimum package of laboratory tests that may be useful in contexts where resources are limited. In addition, it considers aspects of health system organization for dealing with yellow fever outbreaks and epidemics.
