in these communities, it is necessary to respond to communities’ diverse needs from an intercultural perspective that allows the application of a holistic approach—from a standpoint of equality and mutual respect—and considers the value of their cultural practices. In the Region of the Americas, although there has been progress toward recognizing the need for an intercultural approach to health services, obstacles rooted in discrimination, racism, and the exclusion of indigenous peoples and other ethnic groups persist. To respond to this situation, the Pan American Health Organization (PAHO) prepared this guidance which––based on an intercultural approach in accordance with the priority lines of the current PAHO Policy on Ethnicity and Health and its practical development in the Region’s indigenous populations––represent a support tool for implementing the End TB Strategy. This publication integrates PAHO’s accumulated experience and best practices developed by its Member States in recent years, including discussions and experiences shared in regional meetings on the issue, and emphasizes innovation and social inclusion. This requires an urgent shift away from traditional paradigms, taking specific actions that gradually reduce TB incidence and moving toward effective multisectoral actions that have proven effective in quickly containing the epidemic.

Recognizing that work remains to be done and that the 2020 target2 for elimination is rapidly approaching, in February 2015 the WHO Department of Control of Neglected Tropical Diseases convened a group of academic institutions that had for many years helped WHO to implement its mandate on trachoma and to work towards establishing a Network of WHO collaborating centres (WHOCCs) for Trachoma. The report of that meeting has been published.

in the process of establishing strategies for antimicrobial stewardship (AMS). Within each country, different healthcare challenges have
contributed to AMR. This has also shaped individual AMS strategies and policies. In South Africa (SA), there is a high burden of infectious diseases, mainly of bacterial origin. In addition, SA also has the highest number of people living with
human immunodeficiency virus (HIV) globally. According to the 2019 statistics, there are approximately 7.97 million people living with HIV in SA. Together with this, SA has the fourth largest tuberculosis population globally.
Other important challenges include poverty, malnutrition, a high burden of non-communicable diseases, and a dire shortage of trained healthcare professionals (e.g. clinicians, pharmacists, and nurses).

Syndromic Pan-African polyvalent antivenoms for neurotoxic envenoming: products that are intended for treatment of envenoming by species whose venoms are neurotoxic. Syndromic Pan-African polyvalent antivenoms for non-neurotoxic envenoming: products for snakebite envenoming where the effects are largely haemorrhagic, necrotic or procoagulant.

Heart failure (HF) is a global public health concern with disproportionate socioeconomic, morbidity and mortality burden on low- and middle-income countries (LMICs). This review summarises contemporary data on the demographic and clinical characteri

stics, aetiologies, treatment, economic burden and outcomes of HF in LMICs. Patients with HF in LMICs are younger than those from high-income countries (HICs) and present at advanced stages of the disease. Hypertension, ischaemic heart disease (IHD), cardiomyopathy (CMO), and rheumatic heart disease (RHD) are the leading causes of HF in LMICs. The contribution of infectious diseases to HF remains prominent in many LMICs. Most health facilities in LMICs lack adequate diagnostic tools for HF, and the use of evidence-based medical and device therapies is suboptimal. Further, HF in LMICs is associated with prolonged hospital stay and high in-hospital and one-year mortality. Finally, HF has profound economic impact on individual patients who, mostly, have no health insurance, and on societies where patients are young, comprising those who have the greatest potential to contribute to economic productivity.

e than those in high-income countries.1 Guideline-directed medical therapy (GDMT) consisting of ACE (angiotensin-converting enzyme) inhibitors or ARB (angiotensin receptor blockers) or ARNI (angiotensin receptor-neprilysin inhibitors), β-blockers, MRA (mineralocorticoid receptor antagonists), and SGLT2 (sodium-glucose cotransporter 2) inhibitors substantially reduces mortality among patients with HFrEF. These medicines are among the most cost-effective interventions and are thus included as the highest priority health system interventions recommended by the Disease Control Priorities Project.2 Despite this high-quality evidence, GDMT remains widely underutilized in low- and middle-income countries resulting in widespread undertreatment of patients with HFrEF due to health system-, provider-, and patient-level barriers.1 National essential medicines lists (EMLs) promoted by the World Health Organization (WHO) guide countries on which medications to purchase in the setting of limited resources and have resulted in higher procurement and availability of essential medicines in the public sector.3 We provide a cross-sectional analysis of national EMLs in 53 low- and middle-income countries, and availability, price, and affordability of GDMT in select countries to identify potential barriers to access to these essential medicines for patients with HFrEF.

Background: COVID-19 is a global public health crisis that affects all sectors; studying the impact of this pandemic on the delivery of cardiology services in Africa is crucial as COVID-19-related cardiovascular complications may worsen the CVD burd
...
en in this already highly affected and resource-limited continent
Methods: This was a cross-sectional e-survey study conducted amongst cardiologists in African countries. The primary outcome was the change in service delivery in African cardiology units during the on-going COVID-19 pandemic. The secondary outcomes were the satisfaction of cardiologists with regards to the workload and factors associated with this satisfaction.
Results: There was a significant reduction in working time and the number of patients consulted by week during this pandemic (p<0.001). In general, there was a decrease in the overall activities in cardiovascular care delivery. The majority of cardiology services (76.5%) and consulting programs (85%) were adjusted to the pandemic. Only half of the participants were satisfied with their workload. Reconfiguration of the consultation schedule was associated with a reduced satisfaction of participants (p=0.02).
Conclusions: COVID-19 is associated with an overall reduction in cardiology services rendered in Africa. Since the cardiovascular burdens continue to increase in this part of the World and the risk of cardiovascular complications linked to SARS COV2 remains unchanged cardiology, departments in Africa should anticipate a significant surge of cardiology services demanded by patients after the COVID-19 pandemic.

Methods: Data on peripheral artery disease were modelled using the Global Burden of Disease, Injuries, and Risk Factors Study (GBD) 2019 database. Prevalence, disability-adjusted life years (DALYs), and mortality estimates of peripheral artery disease were extracted from GBD 2019. Total DALYs and age-standardised DALY rate of peripheral artery disease attributed to modifiable risk factors were also assessed.

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 conce
...
ntration within them is lower than normal, affecting 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).
