Trypanosoma cruzi is the etiological agent of Chagas disease (CD), considered one of the most important parasitic infections in Latin America. Between 25 and 90 million humans are at infection risk via at least one of multiple infection mechanisms. Under natural conditions, the principal transmissio...n modes are transplacental or via one of more than 140 hematophagous triatomine bugs (Reduviidae: Triatominae). Triatomines acquire the parasite from mammal reservoirs due to their obligate blood-feeding (albeit triatomines can also feed on non-reservoir vertebrates such as birds and reptiles). The disease burden for CD in the Latin America and Caribbean region, based on disability-adjusted life-years (DALYs), is at least five times greater than that of malaria, and is approximately one-fifth that of HIV/AIDS. In recent decades, CD has extended to other continents outside natural reservoir or vector distributions due to human migration, with a minimum estimated 10 million individuals infected worldwide.

Epidemiology
Chagas disease (American trypanosomiasis) is caused by the protozoan parasite Trypanosoma cruzi, and transmitted to humans by infected triatomine bugs, and less commonly by transfusion, organ transplant, from mother to infant, and in rare instances, by ingestion of contaminated food or... drink.1-4 The hematophagous triatomine vectors defecate during or immediately after feeding on a person. The parasite is present in large numbers in the feces of infected bugs, and enters the human body through the bite wound, or through the intact conjunctiva or other mucous membrane.
Vector-borne transmission occurs only in the Americas, where an estimated 8 to 10 million people have Chagas disease.5 Historically, transmission occurred largely in rural areas in Latin America, where houses built of mud brick are vulnerable to colonization by the triatomine vectors.4 In such areas, Chagas disease usually is acquired in childhood. In the last several decades, successful vector control programs have substantially decreased transmission rates in much of Latin America, and large-scale migration has brought infected individuals to cities both within and outside of Latin America.

These guidelines have been compiled for education ministries or other educational leaders (including development partners, non-governmental or private organizations working with schools or directly with caregivers) who want to adapt and adopt resources to support the marginalized caregivers of child...ren with disabilities.
The guidance presented in this document was developed by a team of international and national experts following a proof-of-concept pilot4 of the resources in two countries. The work was carried out between February 2021 and January 2022. The pilots demonstrated that principles and activities described in the resources could be carried out, in practical terms, in line with existing government programmes supporting the implementation of disability-inclusive education.

Sleeping sickness is controlled by case detection and treatment but this often only reaches less than 75% of the population. Vector control is capable of completely interrupting HAT transmission but is not used because of expense. We conducted a full scale field trial of a refined vector control tec...hnology. From preliminary trials we determined the number of insecticidal tiny targets required to control tsetse populations by more than 90%. We then carried out a full scale, 500 km2 field trial covering two HAT foci in Northern Uganda (overall target density 5.7/km2). In 12 months tsetse populations declined by more than 90%. A mathematical model suggested that a 72% reduction in tsetse population is required to stop transmission in those settings. The Ugandan census suggests population density in the HAT foci is approximately 500 per km2. The estimated cost for a single round of active case detection (excluding treatment), covering 80% of the population, is US$433,333 (WHO figures). One year of vector control organised within country, which can completely stop HAT transmission, would cost US$42,700. The case for adding this new method of vector control to case detection and treatment is strong. We outline how such a component could be organised.

Mycetoma is a specific chronic, granulomatous, inflammatory disease. It usually involves the subcutaneous tissue, most probably after traumatic inoculation of the causative organism. It has a prolonged, progressive, and indolent course, and, if untreated, it ultimately leads to destruction of the de...eper tissues and bone, resulting in deformity and disability that may necessitate amputation of the affected parts with all the social and economic implications of this. The disease is characterized by tumefaction, draining sinuses, and the presence of grains.

Little is known about foreign aid provided by private donors. This paper contributes to closing this research gap by comparing the allocation of private humanitarian aid to that of official humanitarian aid awarded to 140 recipient countries over the 2000-2016 period. We construct a new database tha...t offers information on the country in which the headquarters of private donors are located to test whether private donors follow the aid allocation pattern of their home country. Our empirical results confirm that private aid “follows the flag.” This finding is robust against the inclusion of various fixed effects, estimating instrumental variables models, and disaggregating private aid into corporate aid and NGO aid. Donor country-specific estimations reveal that private aid from China, Sweden, the United Kingdom, and the United States “follow the flag.”

This publication provides an overview of UN Women’s commitments to the humanitarian community guided by the “UN Women strategic plan 2022–2025”. It highlights areas where UN Women has a unique advantage in advancing gender equality and the empowerment of women and girls across the humanitari...an–development–peace nexus, and in contributing to the Inter-Agency Standing Committee priorities, including localization and accountability to affected people.
The strategy adopts a two-pronged approach:
strengthening accountability towards gender commitments in coordination and implementation of UN-led humanitarian and refugee responses, and
strengthening comprehensive protection and livelihoods support to crisis-affected women and girls.
While taking these approaches, UN Women prioritizes amplifying women’s voices, leadership, and agency as a critical and enabling cross-cutting area.

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 impacts of climate change. Increased frequency and inten...sity 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.

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
Chronic congestive heart failure is a common condition that, if untreated, markedly impairs the quality of life and is associated with a high risk of recurrent hospitalization and death.
Methods
This review is based on articles retrieved by a selective search in PubMed, as well as on r...elevant guidelines.
Results
Evidence-based treatment options are available only for congestive heart failure with a low ejection fraction. Pharmacotherapy is based on neurohumoral inhibition of the renin-angiotensin-aldosterone system and the adrenergic system. The prognosis of patients with this condition has been further improved recently through the introduction of combined angiotensin receptor antagonists and neprilysin inhibitors. Modern implantable devices are a further component of treatment. Implantable defibrillators and special pacemakers for cardiac resynchronization are well established; the utility of alternative devices (baroreflex modulation or cardiac contractility modulation) needs to be investigated in further studies. It was recently shown that the catheter-based treatment of secondary mitral regurgitation with a MitraClip improves the outcome of selected patients.
Conclusion
The treatment of chronic systolic heart failure as recommended in the relevant guidelines, with drugs and implanted devices if indicated, can significantly improve the clinical outcome.

Asia remained the world’s most disaster-hit region from weather, climate and water-related hazards in 2023. Floods and storms caused the highest number of reported casualties and economic losses, whilst the impact of heatwaves became more severe, according to a new report from the World Meteorolog...ical Organization (WMO).
The State of the Climate in Asia 2023 report highlighted the accelerating rate of key climate change indicators such as surface temperature, glacier retreat and sea level rise, which will have major repercussions for societies, economies and ecosystems in the region.
In 2023, sea-surface temperatures in the north-west Pacific Ocean were the highest on record. Even the Arctic Ocean suffered a marine heatwave.
Asia is warming faster than the global average. The warming trend has nearly doubled since the 1961–1990 period.

The article "Under- and over-diagnosis of COPD: a global perspective" reviews the worldwide variation in the prevalence of chronic obstructive pulmonary disease (COPD) and issues related to its misdiagnosis. It highlights that COPD is under-diagnosed due to factors such as limited access to spiromet...ry and variable diagnostic criteria, especially in low- and middle-income countries. Conversely, over-diagnosis often results from reliance on non-standard criteria or inadequate spirometry use. The article discusses key risk factors, including age, gender, exposure to pollutants, and comorbidities, and emphasizes the need for standardized diagnostic practices to better address and manage COPD globally.
