Climate change is one of the most urgent challenges for people and ecosystems worldwide. The recently published sixth Assessment Report (AR6) of the Intergovernmental Panel on Climate Change (IPCC) stresses the occurrence of widespread adverse impact...>s of climate change. Increased frequency and intensity of extreme weather events, as well as slow-onset processes cause enormous losses and damages to human and natural systems. Marginalized groups and people in vulnerable situations are often disproportionally affected. While the impacts of climate change already become more tangible and threatening, action for addressing them remains insufficient. Adaptation to climate change is, thus, becoming a necessity for governments, companies, and private citizens.
To provide practical and scientifically sound guidance on how to conduct vulnerability assessments, GIZ published its Vulnerability Sourcebook in 2014. The Vulnerability Sourcebook was used in over twenty different GIZ partner countries and provides a step-by-step guidance for designing and implementing a vulnerability assessment. It is also one of the methodological foundations for the ISO 14091:2021 standard on vulnerability, impacts and risk assessment for climate change adaptation.

Since fighting between the Sudanese Armed Forces (SAF) and the Rapid Support Forces (RSF) erupted in mid-April, an estimated 6.3 million people have fled their homes, taking refuge inside and outside the country, with children representing about half of the people displaced. Sudan is now the country... with the largest number of displaced people in the world as prior to the fighting there were 3.7 million people internally displaced in Sudan. It is also now the country with the largest child displacement crisis in the world. ACLED estimates that more than 10,400 people have been killed since the fighting broke out in April, of which about 1,300 killings happened between 30 September and 27 October.

Peripheral artery disease (PAD) is the most underdiagnosed, underestimated and undertreated of the atherosclerotic vascular diseases despite its poor prognosis. There may be racial or contextual differences in the Asia-Pacific region as to epidemiology, availability of diagnostic and therapeutic mod...alities, and even patient treatment response. The Asian Pacific Society of Atherosclerosis and Vascular Diseases (APSAVD) thus coordinated the development of an Asia-Pacific Consensus Statement (APCS) on the Management of PAD.

After the earthquake in Türkiye-Syria in February 2023 an emergency response was provided to the affected population. Young persons with disabilities were one of the social groups most affected by the crisis. These were either young persons who acquired a disability due to the earthquake, or young ...persons with disabilities who were further isolated after the crisis due to compounded and structural barriers.
In response to this situation the Compact for Young People in Humanitarian Action reached out to the Youth2030 Disability Task Team with the aim of supporting humanitarian teams in the field. The current version of this checklist has been developed for a broader context not only for the Türkiye-Syria case, but also for other humanitarian crises. This checklist aims to provide guidance on how to ensure meaningful participation of young persons with disabilities in local humanitarian response. The expected users are humanitarian actors, especially those working in the field.

Background
Cardiovascular diseases (CVDs) are one of the global leading causes of concern due to the rising prevalence and consequence of mortality and disability with a heavy economic burden. The objective of the current study was to analyze the trend in CVD incidence, mortality, and mortality-to-...incidence ratio (MIR) across the world over 28 years.
Methods
The age-standardized CVD mortality and incidence rates were retrieved from the Global Burden of Disease (GBD) Study 2017 for both genders and different world super regions with available data every year during the period 1990–2017. Additionally, the Human Development Index was sourced from the United Nations Development Programme (UNDP) database for all countries at the same time interval. The marginal modeling approach was implemented to evaluate the mean trend of CVD incidence, mortality, and MIR for 195 countries and separately for developing and developed countries and also clarify the relationship between the indices and Human Development Index (HDI) from 1990 to 2017.
Results
The obtained estimates identified that the global mean trend of CVD incidence had an ascending trend until 1996 followed by a descending trend after this year. Nearly all of the countries experienced a significant declining mortality trend from 1990 to 2017. Likewise, the global mean MIR rate had a significant trivial decrement trend with a gentle slope of 0.004 over the time interval. As such, the reduction in incidence and mortality rates for developed countries was significantly faster than developing counterparts in the period 1990–2017 (p < 0.05). Nevertheless, the developing nations had a more rather shallow decrease in MIR compared to developed ones.
Conclusions
Generally, the findings of this study revealed that there was an overall downward trend in CVD incidence and mortality rates, while the survival rate of CVD patients was rather stable. These results send a satisfactory message that global effort for controlling the CVD burden was quite successful. Nonetheless, there is an urgent need for more efforts to improve the survival rate of patients and lower the burden of this disease in some areas with an increasing trend of either incidence or mortality.

Buruli ulcer (BU) is a bacterial skin infection that is caused by Mycobacterium ulcerans and mainly affects people who reside in the rural areas of Africa and in suburban and beach resort communities in Australia.
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.

Patients with diabetes are at increased risk of developing cardiovascular disease (CVD) with its manifestations of coronary artery disease (CAD), heart failure (HF), atrial fibrillation (AF), and stroke, as well as aortic and peripheral artery diseases. In addition, diabetes is a major risk factor f...or developing chronic kidney disease (CKD), which in itself is associated with developing CVD. The combination of diabetes with these cardio-renal comorbidities enhances the risk not only for cardiovascular (CV) events but also for CV and all-cause mortality. The current European Society of Cardiology (ESC) Guidelines on the management of cardiovascular disease in patients with diabetes are designed to guide prevention and management of the manifestations of CVD in patients with diabetes based on data published until end of January 2023. Over the last decade, the results of various large cardiovascular outcome trials (CVOTs) in patients with diabetes at high CV risk with novel glucose- lowering agents, such as sodium–glucose co-transporter-2 (SGLT2) inhibitors and glucagon-like peptide-1 (GLP-1) receptor agonists (RAs), but also novel non-steroidal mineralocorticoid receptor antagonists (MRAs), such as finerenone have substantially expanded available therapeutic op-
tions, leading to numerous evidence-based recommendations for the management of this patient population.

Long Acting Muscarinic Antagonists (LAMA) such as tiotropium and glycopyrronium are used in the management of COPD1. They have been shown to improve lung function, quality of life and exercise tolerance. They have also been associated with reduced COPD-related exacerbations, associated hospitalisati...ons and duration of hospital stay. Both the South African Thoracic Society (SATS) and Global Initiative for Chronic Obstructive Lung Disease (GOLD), guidelines recommend the use of long acting anticholinergic drugs (or long acting beta agonists) in moderate to very severe disease as defined by lung function (FEV1). The most up to date guideline, utilizing the GRADE methodology (European Respiratory Society guidelines of 2017), confirms their superiority over long acting β agonists (LABA) as monotherapy for COPD in that LAMA's have demonstrated greater efficacy in terms of exacerbation reduction, with similar safety profile.2 These recommnedations are supported by published peer-reviewed
evidence including individual papers and Cochrane reviews.

Diabetes mellitus is a major cause of morbidity and mortality in Scotland and worldwide, with an increasing prevalence. In 2009 there were around 228,000 people registered as having diabetes in Scotland, an increase of 3.6% from the preceding year. This increase relates, in part, to the increasing a...ge of the population, an increase in obesity and also perhaps to increasing survival of those with diabetes.

In recent decades, India has witnessed a rapidly exploding epidemic of diabetes.
Indeed, India today has the second largest number of people with diabetes in the
world. The International Diabetes Federation (IDF) estimates that there are 72.9 million people with diabetes in India in 2017, which is... projected to rise to 134.3 million by the year 2045. The prevalence of diabetes in urban India, especially in large metropolitan cities has increased from 2% in the 1970s to over 20% at present and the rural areas are also fast catching up.

Asthma is the most common chronic respiratory disease among school-going adolescents worldwide. However, the burden of severe asthma is highest in Sub-Saharan Africa. This study aimed to explore teachers’ perceptions of asthma care across six African countries. We conducted focus group discussions... (FGDs) using a semi-structured interview guide. Interviews were audio-recorded, transcribed verbatim and analysed thematically. FGDs were conducted in Kumasi(Ghana), Blantyre (Malawi), Lagos (Nigeria), Durban (South Africa), Kampala (Uganda), and Harare (Zimbabwe) between 01 November 2020 and 30 June 2021. We identified two key themes related to asthma care; barriers to asthma care and suggestions to improve the care of adolescents with asthma. Barriers reported by teachers included a lack of knowledge and skills among themselves, adolescents, and caregivers. In addition, some traditional beliefs of teachers on asthma exacerbated challenges with asthma care in schools. Regarding suggestions, most teachers identified a need for all-inclusive asthma training programmes for teachers, adolescents and caregivers, focusing on acute episodes and mitigating triggers. Utilising teachers with personal experiences with asthma to advocate and support these initiatives was suggested. Further suggestions included the need for annual screening to enable early identification of adolescents with asthma and clarify restrictions on teachers administering asthma medications. Teachers across African schools identify multiple barriers to asthma care. Structured school education programs and annual asthma screening are key to addressing some barriers to care.

Under-diagnosis of asthma in ‘under-fives’ may be alleviated by improved inquiry into disease history. We assessed a questionnaire-based screening tool for asthma among 614 ‘under-fives’ with severe respiratory illness in Uganda. The questionnaire responses were compared to post hoc consensu...s diagnoses by three pediatricians who were guided by study definitions that were based on medical history, physical examination findings, laboratory and radiological tests, and response to bronchodilators. Children with asthma or bronchiolitis were categorized as “asthma syndrome”. Using this approach, 253 (41.2%) had asthma syndrome. History of and present breathing difficulties and present cough and wheezing was the best performing combination of four questionnaire items [sensitivity 80.8% (95% CI 77.6–84.0); specificity 84.7% (95% CI 81.8–87.6)]. The screening tool for asthma syndrome in ‘under-fives’ may provide a simple, cheap and quick method of identifying children with possible asthma. The validity and reliability of this tool in primary care settings should be tested.

Long-term polio vaccine security – the timely, sustained, and uninterrupted supply of suitable types of affordable, quality-assured polio vaccines – is essential in the global effort to achieve and maintain a polio free world. However, fragmented approaches and short-term planning pose considera...ble challenges to securing long-term polio vaccine security.
This framework is designed to enhance the efforts of existing structures and workstreams within the Global Polio Eradication Initiative (GPEI) and other stakeholders by improving communication and coordination on vaccine security. Ensuring vaccine security is crucial for maintaining a timely, sustained, and uninterrupted supply of affordable, quality-assured polio vaccines in the global fight to achieve and sustain a polio-free world. However, challenges such as fragmented approaches, short-term planning, a dynamic policy environment, and a diverse product pipeline present significant risks to long-term vaccine security. This framework emphasizes the need for alignment and coordination across key polio operational domains, including Poliovirus Containment, Research and Development, and Vaccine Manufacturing and Supply. It also underscores the critical role of normative frameworks and policies in shaping long-term vaccine strategies that guide these operational areas. Additionally, it highlights the importance of cross-cutting elements such as financing and access to resources, along with the integration of communication, coordination, and advocacy efforts, as essential enablers for achieving vaccine security. To secure long-term vaccine supply, it is imperative to enhance alignment and strengthen coordinated efforts across workstreams and with stakeholders, including vaccine manufacturers.
Recognizing that vaccine security is an ongoing endeavor, requiring continuous monitoring and adaptation, this framework will undergo regular updates and revisions. Initially, the management of the framework will be carried out by the GPEI Vaccine Supply Group (VSG).
