Ebola disease and Marburg disease outbreaks continue to occur in Africa, with increased frequency. In addition to resulting in high mortality and morbidity, the outbreaks generate fear and mistrust about the response activities within the communities affected.
Infection prevention and control (IP...C) is a key pillar in the outbreak response; adherence to IPC practices can prevent and control transmission of infections to health and care workers, patients and their family members.
During the 2014-2016 West African Ebola disease outbreak, there was an urgent need for rapid IPC guidance to help support ministries of health, health-care providers and non-governmental organizations (NGOs). In response, WHO produced several documents related to the outbreak based on expert opinion, including IPC-specific documents and documents on clinical management that also referenced key IPC principles and practices. Since that time, many practices in the field have become institutionalized.

WHO/Europe has launched a new guide, providing support to countries on how to apply behavioural and cultural insights (BCI) for health. It presents a simple step-wise approach, complemented by a rich collection of detailed considerations, tools and exercises. The guide is the first of its kind, spec...ifically developed for use by public health professionals developing policies, services and communications informed by BCI across health topics.
Some of the most persistent public health challenges involve human behaviour. Using a BCI lens means that health policies, services and communications can be tailored to the needs and circumstances of people and communities, and thereby help combat these challenges. The new Tailoring Health Programmes (THP) guide describes how this can be done.
Building on several topic-specific guides that focused on applying BCI to routine and influenza vaccination and tackling antimicrobial resistance, as well as external evaluations and a rigorous peer-review process, this guide is the result of over a decade of work by WHO/Europe. The THP approach has already been adopted in over 20 countries and has received positive feedback from public health agencies.
“This guide is the culmination of a decade of work involving many colleagues at country, regional and global levels. The guide is our “BCI bible”, guiding our work with and in countries to help tackle persistent health challenges,” said Katrine Bach Habersaat, Regional Advisor for BCI at WHO/Europe.
Karina Godoy, Senior Analyst and National Focal Point for Behavioural Insights at the Public Health Agency of Sweden, who is employing the approach described in the guide across several health projects, comments: “The THP guide is easy to use and at the same time provides detailed guidance and inspiration where needed. We have decided to translate the document into Swedish and use the approach widely”.

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.

Atherosclerotic lower-extremity peripheral artery disease (PAD) is increasingly recognized as an important cause of cardiovascular morbidity and mortality that affects more than 230 million people worldwide. Traditional cardiovascular risk factors, including advanced age, smoking, and diabetes, are ...strongly linked to an increase risk of PAD. Although PAD has been historically underappreciated compared to coronary artery disease and stroke, greater attention on PAD in recent years has led to important new epidemiologic insights in the areas of thrombosis, inflammation, dyslipidemia, and microvascular disease. In addition, the concept of polyvascular disease, or clinically-evident atherosclerosis in multiple arterial beds, is increasingly identified as a particularly malignant cardiovascular disease worthy of special clinical attention and further study. It is noteworthy that PAD may increase the risk of adverse outcomes in similar or even greater magnitude than coronary disease or stroke. In this review, we highlight important new advances in the epidemiology of PAD with a particular focus on polyvascular disease, emerging biomarkers, and differential risk pathways for PAD compared to other atherosclerotic diseases.

Background
Noncommunicable diseases are major contributors to morbidity and mortality worldwide. Modifying the risk factors for these conditions, such as physical inactivity, is thus essential. Addressing the context or circumstances in which physical activity occurs may promote physical activity a...t a population level. We assessed the effects of infrastructure, policy or regulatory interventions for increasing physical activity.
Methods
We searched PubMed, Embase and clinicaltrials.gov to identify randomised controlled trials (RCTs), controlled before-after (CBAs) studies, and interrupted time series (ITS) studies assessing population-level infrastructure or policy and regulatory interventions to increase physical activity. We were interested in the effects of these interventions on physical activity, body weight and related measures, blood pressure, and CVD and type 2 diabetes morbidity and mortality, and on other secondary outcomes. Screening and data extraction was done in duplicate, with risk of bias was using an adapted Cochrane risk of bias tool. Due to high levels of heterogeneity, we synthesised the evidence based on effect direction.
Results
We included 33 studies, mostly conducted in high-income countries. Of these, 13 assessed infrastructure changes to green or other spaces to promote physical activity and 18 infrastructure changes to promote active transport. The effects of identified interventions on physical activity, body weight and blood pressure varied across studies (very low certainty evidence); thus, we remain very uncertain about the effects of these interventions. Two studies assessed the effects of policy and regulatory interventions; one provided free access to physical activity facilities and showed that it may have beneficial effects on physical activity (low certainty evidence). The other provided free bus travel for youth, with intervention effects varying across studies (very low certainty evidence).
Conclusions
Evidence from 33 studies assessing infrastructure, policy and regulatory interventions for increasing physical activity showed varying results. The certainty of the evidence was mostly very low, due to study designs included and inconsistent findings between studies. Despite this drawback, the evidence indicates that providing access to physical activity facilities may be beneficial; however this finding is based on only one study. Implementation of these interventions requires full consideration of contextual factors, especially in low resource settings.

Diphtheria is caused by Corynebacterium species, mostly by toxin-producing Corynebacterium diphtheriae and rarely by toxin-producing strains of C. ulcerans and C. pseudotuberculosis. The most common type of diphtheria is classic respiratory diphtheria, whereby the exotoxin produced characteristicall...y causes the formation of a pseudomembrane in the upper respiratory tract and damages other organs, usually the myocardium and peripheral nerves. Acute respiratory obstruction, acute systemic toxicity, myocarditis and neurologic complications are the usual causes of death. The infection can also affect the skin (cutaneous diphtheria). More rarely, it can affect mucous membranes at other non-respiratory sites, such as genitalia and conjunctiva.
C. diphtheriae is transmitted from person to person by intimate respiratory and direct contact; in contrast, C. ulcerans and C. pseudotuberculosis are zoonotic infections, not transmitted person-to-person. The incubation period of C. diphtheriae is two to five days (range 1– 10 days). A person is infectious as long as virulent bacteria are present in respiratory secretions, usually two weeks without antibiotics, and seldom more than six weeks. In rare cases, chronic carriers may shed organisms for six months or more. Skin lesions are often chronic and infectious for longer periods. Effective antibiotic therapy (penicillin or erythromycin) promptly terminates shedding in about one or two days.

Socioeconomic status is associated with differences in risk factors for cardiovascular disease incidence and outcomes, including mortality. However, it is unclear whether the associations between cardiovascular disease and common measures of socioeconomic status—wealth and education—differ among... high-income, middle-income, and low-income countries, and, if so, why these differences exist. We explored the association between education and household wealth and cardiovascular disease and mortality to assess which marker is the stronger predictor of outcomes, and examined whether any differences in cardiovascular disease by socioeconomic status parallel differences in risk factor levels or differences in management.

While epidemiological data for type 1 diabetes (T1D) in low/middle-income countries, and particularly low-income countries (LICs) including Liberia is lacking, prevalence in LICs is thought to be increasing. T1D care in LICs is often impacted by challenges in diagnosis and management. These challeng...es, including misdiagnosis and access to insulin, can affect T1D outcomes and frequency of severe complications. Despite the severe nature of T1D and growing burden in subSaharan Africa, little is currently known about the impact of T1D on patients and caregivers in the region. Methods We conducted a qualitative study consisting of interviews with patients with T1D, caregivers, providers, civil society members and a policy-maker in Liberia to better understand the psychosocial and economic impact of living with T1D, knowledge of T1D and selfmanagement, and barriers and facilitators for accessing T1D care.

Objectives Our study aimed to systematically review the literature and synthesise findings on potential associations of built environment characteristics with type 2 diabetes (T2D) in Asia.
sthma prevalence is increasing worldwide, and surveys indicate that most patients in developed and developing countries, including South Africa, do not receive optimal care and are therefore not well controlled. Standard management guidelines adapted to in-country realities are important to support ...optimal care. The South African Thoracic Society (SATS) first published a guideline for the management of chronic persistent asthma in 1992, which has subsequently been revised several times.
The main aim of the present document was to revise and update SATS’ statement on the suggested management of chronic asthma, based on the need to promote optimal care and control of asthma, together with the incorporation of new concepts and drug developments. This revised document reinforces optimal care and incorporates the following primary objectives to achieve the recent advances in asthma care:
• continued emphasis on the use of inhaled corticosteroids (ICS) as the foundation of asthma treatment
• to reduce the reliance on short-acting beta-2 agonist (SABA) monotherapy for asthma symptoms
• to incorporate the evidence and strategy for the use of the combination of an ICS and formoterol for acute symptom relief (instead of a SABA)
• to incorporate the evidence and strategy for the use of as-needed ICS-long-acting beta agonists (LABA) for patients with infrequent symptoms or ‘mild’ asthma
• to incorporate the evidence and strategy for the use of a long-acting muscarinic antagonist (LAMA) in combination with ICS-LABA; and
• to incorporate the evidence and strategy for the use of and management with a biologic therapy in severe asthma.
