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). ...-highlight medbox">Moreover, HF patients with 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.

Humanitarian crises exacerbate nutritional risks and often lead to an increase in acute malnutrition. Emergencies include both manmade (conflict) and natural disasters (floods, drought, cyclones, typhoons, earthquakes, volcanic eruptions, etc.). Complex emergencies are combinations of both manmade a...nd natural disasters, often of a protracted nature. Millions of people are affected by humanitarian crises every year. The increasing frequency and scale of emergencies requires nutrition to be addressed in all phases of a response.
Crisis situations, whether acute or protracted, impact on a range of factors that can increase the risk of undernutrition, morbidity, and mortality. They may involve: the large-scale destruction of property and infrastructure; the erosion of livelihood strategies and purchasing power; a breakdown of and reduced access to essential services, including health services, water supply, and sanitation; and the displacement of large numbers of people. Emergencies can also disrupt social systems and the quality of care/feeding practices. Household access to food may be negatively affected and people may find themselves in overcrowded settlements with their families divided. As a result, at the individual level, there is often an increased risk of deteriorating health and nutritional status, resulting in a greater likelihood of death.

Anaemia is a serious global public health problem that particularly affects young children, menstruating adolescent girls and women, and pregnant and postpartum women. It is a condition in which the number of red blood cells or the haemoglobin concentration within them is lower than normal, affectin...g the blood’s ability to carry oxygen to the body’s tissues.
To reliably monitor the prevalence of anaemia at a population level, it is vital to measure the haemoglobin concentration in an accurate and precise way. In large-scale surveys, however, haemoglobin is most commonly measured using single-drop capillary blood specimens in point-of-care devices. Emerging evidence suggests that the use of single-drop capillary blood can introduce random and/or systematic errors, which may lead to inaccurate estimates, complicating effective anaemia programming.
This technical brief describes the current best practices for haemoglobin measurement, providing guidance to help plan or implement field surveys to assess anaemia at a population level. Continuing work to review emerging evidence is led by members of the WHO-UNICEF Technical Expert Advisory group on nutrition Monitoring (TEAM).

Developed as part of the UN Women–WHO Global Joint Programme on Violence Against Women Data, this briefing note focuses on the measurement of violence against women with disability and is one in a series of methodological briefing notes for strengthening the measurement and data collection of viol...ence against particular groups of women or specific aspects of violence against women.
The briefing note is meant for researchers, national statistics offices, and others involved in data collection on violence against women. It provides an overview of the challenges in the availability, measurement, and collection of data on violence against women with disability and outlines recommendations for good practice in measurement, with the aim of strengthening ongoing and future data collection efforts and increasing the availability of such data.
The inclusion of women with disability and the issue of disability within population-based surveys and research on violence against women is necessary for an improved understanding of populations of women at specific risk of violence. This knowledge would also allow more tailored prevention strategies and response/services and programmes to be designed in a way that addresses the specific needs of women with disability.

Background: Community health worker (CHW) programmes are a valuable component of primary care in resource-poor settings. The evidence supporting their effectiveness generally shows improvements in disease-specific outcomes relative to the absence of a CHW programme. In this study, we evaluated expan...ding an existing HIV and tuberculosis (TB) disease-specific CHW programme into a polyvalent, household-based model that subsequently included non-communicable diseases (NCDs), malnutrition and TB screening, as well as family planning and antenatal care (ANC).
Methods: We conducted a stepped-wedge cluster randomised controlled trial in Neno District, Malawi. Six clusters of approximately 20 000 residents were formed from the catchment areas of 11 healthcare facilities. The intervention roll-out was staggered every 3 months over 18 months, with CHWs receiving a 5-day foundational training for their new tasks and assigned 20–40 households for monthly (or more frequent) visits.
Findings: The intervention resulted in a decrease of approximately 20% in the rate of patients defaulting from chronic NCD care each month (−0.8 percentage points (pp) (95% credible interval: −2.5 to 0.5)) while maintaining the already low default rates for HIV patients (0.0 pp, 95% CI: −0.6 to 0.5). First trimester ANC attendance increased by approximately 30% (6.5pp (−0.3, 15.8)) and paediatric malnutrition case finding declined by 10% (−0.6 per 1000 (95% CI −2.5 to 0.8)). There were no changes in TB programme outcomes, potentially due to data challenges.

Since the Alma Ata Declaration in 1978, community health volunteers (CHVs) have been at the forefront, providing health services, especially to underserved communities, in low-income countries. However, consolidation of CHVs position within formal health systems has proved to be complex and continue...s to challenge countries, as they devise strategies to strengthen primary healthcare. Malawi’s community health strategy, launched in 2017, is a novel attempt to harmonise the multiple health
service structures at the community level and strengthen service delivery through a team-based approach. The core community health team (CHT) consists of health surveillance assistants (HSAs), clinicians, environmental health officers and CHVs. This paper reviews Malawi’s strategy, with particular focus on the interface between HSAs, volunteers in community-based programmes and
the community health team. Our analysis identified key challenges that may impede the strategy’s implementation:
(1) inadequate training, imbalance of skill sets within CHTs and unclear job descriptions for CHVs; (2) proposed community-level interventions require expansion of pre-existing roles for most CHT members; and (3) district authorities may face challenges meeting financial obligations and filling community-level positions. For effective implementation, attention and further deliberation is needed on the appropriate forms of CHV support, CHT composition with possibilities of co-opting trained CHVs
from existing volunteer programmes into CHTs, review of CHT competencies and workload, strengthening coordination and communication across all community actors, and financing mechanisms. Policy support through the development of an addendum to the strategy, outlining opportunities for task-shifting between CHT members, CHVs’ expected duties and interactions with paid CHT personnel is recommended.

This global status report on prevention and control of NCDs (2014), is framed around the nine voluntary global targets. The report provides data on the current situation, identifying bottlenecks as well as opportunities and priority actions for attaining the targets. The 2010 baseline estimates on N...CD mortality and risk factors are provided so that countries can report on progress, starting in 2015. In addition, the report also provides the latest available estimates on NCD mortality (2012) and risk factors, 2010-2012.All ministries of health need to set national NCD targets and lead the development and implementation of policies and interventions to attain them. There is no single pathway to attain NCD targets that fits all countries, as they are at different points in their progress in the prevention and control of NCDs and at different levels of socioeconomic development. However all countries can benefit from the comprehensive response to attaining the voluntary global targets presented in this report.

Providing quality, stigma-free services is essential to equitable health care for all and achieving global HIV goals and broader Sustainable Development Goals related to health. Every person has the right to the highest attainable standard of physical and mental health. Countries have a legal obliga...tion to develop and implement legislation and policies that guarantee universal access to quality health services and address the root causes of health disparities, including poverty, stigma and discrimination.
The health sector is uniquely placed to lead in addressing inequity, assuring safe personcentred care for everyone and improving social determinants of health by overcoming taboos and discriminatory or stigmatizing behaviours associated with HIV, viral hepatitis and sexually transmitted infections (STIs). Improving health care quality and reducing stigma work together to enhance health outcomes for people living with HIV. Together, they make health care services more accessible, trustworthy and supportive. This encourages early diagnosis, consistent treatment and improved mental well-being. Thus, people living with HIV are more likely to engage with and benefit from health care services, leading to improved overall health.

Asthma is the most common chronic condition in children worldwide. It affects daytime activities, sleep and school attendance and causes anxiety to parents, families and other carers. The quality of asthma diagnosis and management globally still needs substantial improvement. From infancy to the tee...nage years, there are age-specific challenges, including both underdiagnosis and overdiagnosis with stigma-related barriers to treatment in some cultures and in adolescents. The Paediatric Asthma Project Plan has been initiated to strengthen diagnosis and management of asthma. This encompasses a vision for the next 10–15 years, building on the knowledge and experience from previous educational projects. It will take into account the educational needs of patients, carers and healthcare professionals as well as the accessibility and affordability of medication, particularly in low and middle-income countries where the prevalence of asthma is rising more rapidly. This overview presents a first step for those involved in the diagnosis and management of childhood asthma to strengthen care for children globally.

Mpox is an emerging zoonotic disease caused by the mpox virus, a member of the Orthopoxvirus genus closely related to the variola virus that causes smallpox. Mpox was first discovered in 1958 when outbreaks of a pox-like disease occurred in monkeys kept for research. The first human case was recorde...d in 1970 in the Democratic Republic of the Congo (DRC) during a period of intensified effort to eliminate smallpox and since then the infection has been reported in a number of African countries. Mpox can spread in humans through close contact, usually skin-to-skin contact, including sexual contact, with an infected person or animal, as well as with materials contaminated with the virus such as clothing, beddings and towels, and respiratory droplets in prolonged face to face contact. People remain infectious from the onset of symptoms until all the lesions have scabbed and healed. The virus may spread from infected animals through handling infected meat or through bites or scratches. Diagnosis is confirmed by polymerase chain reaction (PCR) testing of material from a lesion for the virus’s DNA. Two separate clades of the mpox virus are currently circulating in Africa: Clade I, which includes subclades Ia and Ib, and Clade II, comprising subclades IIa and IIb. Clade Ia and Clade Ib have been associated with ongoing human-to-human transmission and are presently responsible for outbreaks in the Democratic Republic of the Congo (DRC), while Clade Ib is also contributing to outbreaks in Burundi and other countries.
In 2022‒2023 mpox caused a global outbreak in over 110 countries, most of which had no previous history of the disease, primarily driven by human-to-human transmission of clade II through sexual contact. In just over a year, over 90,000 cases and 150 deaths were reported to the WHO. For the second time since 2022, mpox has been declared a global health emergency as the virus spreads rapidly across the African continent. On 13 Aug 2024, Africa CDC declared the ongoing mpox outbreak a Public Health Emergency of Continental Security (PHECS), marking the first such declaration by the agency since its inception in 2017.7 This declaration empowered the Africa CDC to lead and coordinate responses to the mpox outbreak across affected African countries. On August 14, 2024, the WHO declared the resurgence of mpox a Public Health Emergency of International Concern (PHEIC) emphasizing the need for coordinated international response.
As of August 2024, Mpox has expanded beyond its traditional endemic regions, with new cases reported in countries including Sweden, Thailand, the Philippines, and Pakistan. Sweden has confirmed its first case of Clade 1 variant, which has been rapidly spreading in Africa, particularly in DRC. The emergence of this new variant raises concerns about its potential for higher lethality and transmission rates outside Africa.
