The cardiovascular disease continuum begins with risk factors such as diabetes mellitus (DM), progresses to vasculopathy and myocardial dysfunction, and finally ends with cardiovascular death. Diabetes is associated with a 2- to 4-fold increased risk for heart failure (HF). Moreover, HF patients wit...h DM have a worse prognosis than those without DM. Diabetes can cause myocardial ischemia via micro- and macrovasculopathy and can directly exert deleterious effects on the myocardium. Hyperglycemia, hyperinsulinemia, and insulin resistance can cause alterations in vascular homeostasis. Then, reduced nitric oxide and increased reactive oxygen species levels favor inflammation leading to atherothrombotic progression and myocardial dysfunction. The classification, diagnosis, and treatment of HF for a patient with and without DM remain the same. Until now, drugs targeting neurohumoral and metabolic pathways improved mortality and morbidity in HF with reduced ejection fraction (HFrEF). Therefore, all HFrEF patients should receive guideline-directed medical therapy. By contrast, drugs modulating neurohumoral activity did not improve survival in HF with preserved ejection fraction (HFpEF) patients. Trials investigating whether sodium-glucose cotransporter-2 inhibitors are effective in HFpEF are on-going. This review will summarize the epidemiology, pathophysiology, and treatment of HF in diabetes.

Objective: To identify gaps in national stroke guidelines that could be bridged to enhance the quality of stroke care services in low- and
middle-income countries.
Methods: We systematically searched medical databases and websites of medical societies and contacted international organizations.
Co...untry-specific guidelines on care and control of stroke in any language published from 2010 to 2020 were eligible for inclusion. We reviewed
each included guideline for coverage of four key components of stroke services (surveillance, prevention, acute care and rehabilitation).
We also assessed compliance with the eight Institute of Medicine standards for clinical practice guidelines, the ease of implementation of
guidelines and plans for dissemination to target audiences.
Findings: We reviewed 108 eligible guidelines from 47 countries, including four low-income, 24 middle-income and 19 high-income countries.
Globally, fewer of the guidelines covered primary stroke prevention compared with other components of care, with none recommending
surveillance. Guidelines on stroke in low- and middle-income countries fell short of the required standards for guideline development;
breadth of target audience; coverage of the four components of stroke services; and adaptation to socioeconomic context. Fewer low- and
middle-income country guidelines demonstrated transparency than those from high-income countries. Less than a quarter of guidelines
encompassed detailed implementation plans and socioeconomic considerations.
Conclusion: Guidelines on stroke in low- and middle-income countries need to be developed in conjunction with a wider category of
health-care providers and stakeholders, with a full spectrum of translatable, context-appropriate interventions.

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.

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.

There is increasing interest in understanding the role of air pollution as one of the greatest threats to human health worldwide. Nine of 10 individuals breathe air with polluted compounds that have a great impact on lung tissue. The nature of the relationship is complex, and new or updated data are... constantly being reported in the literature. The goal of our review was to summarize the most important air pollutants and their impact on the main respiratory diseases (chronic obstructive pulmonary disease, asthma, lung cancer, idiopathic pulmonary fibrosis, respiratory infections, bronchiectasis, tuberculosis) to reduce both short- and the long-term exposure consequences. We considered the most important air pollutants, including sulfur dioxide, nitrogen dioxide, carbon monoxide, volatile organic compounds, ozone, particulate matter and biomass smoke, and observed their impact on pulmonary pathologies. We focused on respiratory pathologies, because air pollution potentiates the increase in respiratory diseases, and the evidence that air pollutants have a detrimental effect is growing. It is imperative to constantly improve policy initiatives on air quality in both high- and low-income countries.

Mpox continues to affect people around the world. A new framework released today by WHO will guide health authorities, communities and other stakeholders in preventing and controlling mpox outbreaks, eliminating human-to-human transmission of the disease, and reducing spillover of the virus from ani...mals to humans.
Mpox is a viral illness caused by the monkeypox virus (MPXV). It can cause a painful rash, enlarged lymph nodes and fever. Most people fully recover, but some get very sick. The virus transmits from person to person through close, including sexual, contact. It also has animal reservoirs in east, central and west Africa, where spillovers from animals to humans can occasionally occur, sparking further outbreaks.
There are two different clades of the virus: clade I and clade II. Clade I outbreaks are deadlier than clade II outbreaks.
A major emergence of mpox linked to clade II began in 2017, and since 2022, has spread to all regions of the world. Between July 2022 and May 2023, the outbreak was declared a Public Health Emergency of International Concern. While that outbreak has largely subsided, cases and deaths continue to be reported today, illustrating that low-level transmission continues around the world.
Currently, there is also a major outbreak of clade I virus in the Democratic Republic of the Congo (DRC), where cases have been on the rise for decades. Since the beginning of the year, over 6500 cases and 345 deaths have been reported in the DRC. Almost half of these are among children under the age of 15 years.
The Strategic framework for enhancing prevention and control of mpox (2024–2027) provides a roadmap for health authorities, communities, and stakeholders worldwide to control mpox outbreaks in every context, advance mpox research and access to countermeasures, and to minimize zoonotic transmission.

The article "Under- and over-diagnosis of COPD: a global perspective" reviews the worldwide variation in the prevalence of chronic obstructive pulmonary disease (COPD) and issues related to its misdiagnosis. It highlights that COPD is under-diagnosed due to factors such as limited access to spiromet...ry and variable diagnostic criteria, especially in low- and middle-income countries. Conversely, over-diagnosis often results from reliance on non-standard criteria or inadequate spirometry use. The article discusses key risk factors, including age, gender, exposure to pollutants, and comorbidities, and emphasizes the need for standardized diagnostic practices to better address and manage COPD globally.

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.
