Cardiovascular diseases remain the leading cause of morbidity and mortality worldwide. There are significant differences in the burden of cardiovascular disease and associated risk factors, across high-income countries and low- and middle-income countries. Cardiac imaging by echocardiography, cardia...c computed tomography, cardiac magnetic resonance imaging, single-photon emission computed tomography, and positron emission tomography myocardial perfusion imaging are well-established non-invasive tests that aid in the diagnosis, risk stratification, and management of various cardiac diseases. However, there are significant inequalities in availability and access to imaging modalities in low- and middle-income countries attributed to financial constraints, disparities in healthcare and technical infrastructure. In the post-COVID-19 pandemic era, these disparities are exaggerated by the continued technological advancements driving innovations in the field of cardiovascular (CV) imaging in high-income countries, while there is an urgent need to provide sustainable access to diagnostic imaging for patients in economically strained healthcare systems in regions like Africa. This review aims to highlight the inequalities in the burden of cardiac disease, associated risk factors, and access to diagnostic CV imaging tests, while also exploring the need for sustainable solutions to implementing CV imaging all over the world.

Each year, ≈795 000 individuals in the United States experience a stroke, of which 87% (690 000) are ischemic and 185 000 are recurrent.1 Approximately 240 000 individuals experience a transient ischemic attack (TIA) each year.2 The risk of recurrent stroke or TIA is high but can be mitiga...ted with appropriate secondary stroke prevention. In fact, cohort studies have shown a reduction in recurrent stroke and TIA rates in recent years as secondary stroke prevention strategies have improved.3,4 A meta-analysis of randomized controlled trials (RCTs) of secondary stroke prevention therapies published from 1960 to 2009 showed a reduction in annual stroke recurrence from 8.7% in the 1960s to 5.0% in the 2000s, with the reduction driven largely by improved blood pressure (BP) control and use of antiplatelet therapy.5 The changes may have been influenced by changes in diagnostic criteria and differing sensitivities of diagnostic tests over the years.

The South African (SA) guidelines for cardiac patients for non-cardiac surgery were developed to address the need for cardiac risk assessment and risk stratification for elective non-cardiac surgical patients in SA, and more broadly in Africa.
The guidelines were developed by updating the Canadian ...Cardiovascular Society Guidelines on Perioperative Cardiac Risk Assessment
and Management for Patients Who Undergo Non-cardiac Surgery, with a search of literature from African countries and recent publications. The updated proposed guidelines were then evaluated in a Delphi consensus process by SA anaesthesia and vascular surgical experts.
The recommendations in these guidelines are:
1. We suggest that elective non-cardiac surgical patients who are 45 years and older with either a history of coronary artery disease, congestive cardiac failure, stroke or transient ischaemic attack, or vascular surgical patients 18 years or older with peripheral vascular disease require further preoperative risk stratification as their predicted 30-day major adverse cardiac event (MACE) risk exceeds 5%
(conditional recommendation: moderate-quality evidence).
2. We do not recommend routine non-invasive testing for cardiovascular risk stratification prior to elective non-cardiac surgery in adults (strong recommendation: low-to-moderate-quality evidence).
3. We recommend that elective non-cardiac surgical patients who are 45 years and older with a history of coronary artery disease, or stroke or transient ischaemic attack, or congestive cardiac failure or vascular surgical patients 18 years or older with peripheral vascular disease should have preoperative natriuretic peptide (NP) screening (strong recommendation: high-quality evidence).
4. We recommend daily postoperative troponin measurements for 48 - 72 hours for non-cardiac surgical patients who are 45 years and older with a history of coronary artery disease, or stroke or transient ischaemic attack, or congestive cardiac failure or vascular surgical patients 18 years or older with peripheral vascular disease, i.e. (i) a baseline risk >5% for MACE 30 days after elective surgery (if no preoperative NP screening), or (ii) an elevated B-type natriuretic peptide (BNP)/N-terminal-prohormone B-type natriuretic peptide (NT-proBNP) measurement before elective surgery (defined as BNP >99 pg/mL or a NT-proBNP >300 pg/mL) (conditional recommendation: moderate-quality evidence).
Additional recommendations are given for the management of myocardial injury after non-cardiac surgery (MINS) and medications for comorbidities.

The World Health Organization (WHO) launched the SAFER initiative in 2018 to address the global health and societal challenges posed by alcohol-related harm. The initiative outlines five key strategies aimed at reducing alcohol consumption and its associated consequences. These include strengthening... restrictions on alcohol availability by implementing and enforcing policies to limit its accessibility and advancing drink-driving countermeasures, such as low blood alcohol concentration limits and random breath testing, to reduce alcohol-impaired driving incidents.
Additionally, SAFER emphasizes facilitating access to screening, brief interventions, and treatment for individuals with alcohol use disorders, ensuring that healthcare systems are equipped to provide effective support. Another core strategy is enforcing comprehensive bans or restrictions on alcohol advertising, sponsorship, and promotion to minimize its influence, particularly on vulnerable populations such as youth. Finally, the initiative advocates raising alcohol prices through excise taxes and pricing policies to make it less affordable and thereby reduce consumption.
By implementing these evidence-based, cost-effective measures, the SAFER initiative aims to reduce the global burden of alcohol-related deaths and disabilities, fostering healthier societies worldwide.

Background
The core clinical symptoms of addiction include an enhanced incentive for drug taking (craving), impaired self-control (impulsivity and compulsivity), emotional dysregulation (negative mood) and increased stress reactivity. Symptoms related to impaired self-control involve reduced activi...ty in anterior cingulate cortex (ACC), adjacent prefrontal cortex (mPFC) and other brain areas. Behavioral training such as mindfulness meditation can increase the function of control networks including those leading to improved emotion regulation and thus may be a promising approach for the treatment of addiction.
Methods
In a series of randomized controlled trials (RCTs), we tested whether increased ACC/mPFC activity is related to better self-control abilities in executive functions, emotion regulation and stress response in healthy and addicted populations. After a brief mindfulness training (Integrative Body-Mind Training, IBMT), we used the Positive and Negative Affect Schedule (PANAS) and Profile of Mood States (POMS) to measure emotion regulation, salivary cortisol for the stress response and fMRI for brain functional and DTI structural changes. Relaxation training was used to serve as an active control.
Results
In both smokers and nonsmokers, improved self-control abilities in emotion regulation and stress reduction were found after training and these changes were related to increased ACC/mPFC activity following training. Compared with nonsmokers, smokers showed reduced ACC/mPFC activity in the self-control network before training, and these deficits were ameliorated after training.
Conclusions
These results indicate that promoting emotion regulation and improving ACC/mPFC brain activity can help for addiction prevention and treatment.

People living with disabilities (PLWDs) have poor access to health services compared to people without disabilities. As a result, PLWDs do not benefit from some of the services provided at health facilities; therefore, new methods need to be developed to deliver these services where PLWDs reside. Th...is case study reports a household-based screening programme targeting PLWDs in a rural district in Malawi. Between March and November 2016, a household-based and integrated screening programme was conducted by community health workers, HIV testing counsellors and a clinic clerk. The programme provided integrated home-based screening for HIV, tuberculosis, hypertension and malnutrition for PLWDs. The programme was designed and implemented for a population of 37 000 people. A total of 449 PLWDs, with a median age of 26 years and about half of them women, were screened. Among the 404 PLWDs eligible for HIV testing, 399 (99%) agreed for HIV testing. Sixty-nine per cent of PLWDs tested for HIV had never previously been tested for HIV. Additionally, 14 patients self-reported to be HIV-positive and all but one were verified to be active in HIV care. A total of 192 of all eligible PLWDs above 18 years old were screened for hypertension, with 9% (n = 17) referred for further follow-up at the nearest facility. In addition, 274 and 371 PLWDs were screened for malnutrition and tuberculosis, respectively, with 6% (n = 18) of PLWDs referred for malnutrition, and 2% (n = 10) of PLWDs referred for tuberculosis testing. We successfully implemented an integrated home-based screening programme in rural Malawi.

DHS Methodological Report No. 20
This study used Service Provision Assessment (SPA) and Demographic and Health Survey (DHS) data from Haiti, Malawi, and Tanzania to compare traditionally used additive methods with a data reduction method—principal component analysis (PCA).
We scored ...the quality of health facilities with three approaches (simple additive, weighted additive, and PCA) for two constructs: quality of services, with only facilities-level data, and quality of care, which incorporates observation and client data. We ranked facilities as high, medium, or low quality based on their scores. Our results indicated that the rankings change with the scoring methodology. There was more consistency in the rankings of facilities by the simple additive and PCA methods than the weighted additive and PCA-based rankings. This may be due to the low factor loadings and little variance explained by the first component in the PCA. We aggregated facility scores to their respective DHS clusters (Haiti, Malawi) or regions (Tanzania) and geographically linked them to women interviewed in DHS surveys to test associations between the use of family planning services and the quality environment, as measured with each index.

To guide One Health capacity building efforts in the Republic of Guinea in the wake of the 2014–2016 Ebola virus disease (EVD) outbreak, we sought to identify and assess the existing systems and structures for zoonotic disease detection and control. We partnered with the government ministries resp...onsible for human, animal, and environmental health to identify a list of zoonotic diseases – rabies, anthrax, brucellosis, viral hemorrhagic fevers, trypanosomiasis and highly pathogenic avian influenza – as the country's top priorities. We used each priority disease as a case study to identify existing processes for prevention, surveillance, diagnosis, laboratory confirmation, reporting and response across the three ministries. Results were used to produce disease-specific systems “maps” emphasizing linkages across the systems, as well as opportunities for improvement. We identified brucellosis as a particularly neglected condition. Past efforts to build avian influenza capabilities, which had degraded substantially in less than a decade, highlighted the challenge of sustainability. We observed a keen interest across sectors to reinvigorate national rabies control, and given the regional and global support for One Health approaches to rabies elimination, rabies could serve as an ideal disease to test incipient One Health coordination mechanisms and procedures. Overall, we identified five major categories of gaps and challenges: (1) Coordination; (2) Training; (3) Infrastructure; (4) Public Awareness; and (5) Research. We developed and prioritized recommendations to address the gaps, estimated the level of resource investment needed, and estimated a timeline for implementation. These prioritized recommendations can be used by the Government of Guinea to plan strategically for future One Health efforts, ideally under the auspices of the national One Health Platform. This work demonstrates an effective methodology for mapping systems and structures for zoonotic diseases, and the benefit of conducting a baseline review of systemic capabilities prior to embarking on capacity building efforts.

In sub-Saharan Africa (SSA), urgent action is needed to curb a growing crisis in cancer incidence and mortality.
Without rapid interventions, data estimates show a major increase in cancer mo...rtality from 520 348 in 2020 to about
1 million deaths per year by 2030. Here, we detail the state of cancer in SSA, recommend key actions on the basis of
analysis, and highlight case studies and successful models that can be emulated, adapted, or improved across the
region to reduce the growing cancer crises. Recommended actions begin with the need to develop or update national
cancer control plans in each country. Plans must include childhood cancer plans, managing comorbidities such as
HIV and malnutrition, a reliable and predictable supply of medication, and the provision of psychosocial, supportive,
and palliative care. Plans should also engage traditional, complementary, and alternative medical practices employed
by more than 80% of SSA populations and pathways to reduce missed diagnoses and late referrals. More substantial
investment is needed in developing cancer registries and cancer diagnostics for core cancer tests.
