Background: Despite several cycles of Mass Drug Administration (MDA), however, the prevalence of Soil-transmitted helminthiasis (STH) remains high in Bangladesh. A clear understanding of local knowledge, attitudes, and practices (KAP) related to the acceptance and utilization of MDA is critical for
...
effective implementation of this intervention.
Methods: This research, a cross-sectional descriptive study that utilized quantitative methods, was conducted between February and June 2017. A total of 380 questionnaire surveys were distributed to school-aged children (SAC), the parents of SAC, and school teachers.
Results: Out of 160 SACs, 81.9% knew of STH and 75.6% knew of MDA. SAC showed a high awareness of STH and recognized the importance of preventive measures and MDA. In terms of the parents of SAC and school teachers, close to half of the respondents were knowledgeable about STH and MDA. While nearly all of the participants held positive attitudes toward MDA, the respondents pointed out that school-based MDA presents severe limitations, as non-school-going children are neglected by this effort. A total of 68.3% of all school teachers and 56.8% of all parents of SAC found MDA efforts to be effective.
Conclusion: STH infections still remain a significant public health burden in Bangladesh. Reforming the MDA policy is necessary to achieve the target of STH elimination.

The chapter Dementia in Latin America and the Caribbean: Prevalence, Incidence, Impact, and Trends over Time, is part of the publication series titled “Decade of Healthy Aging: situation and challenges”. This document aims to provide an outline of the current situation in Latin America and the C
...
aribbean in respect of the prevalence and incidence of dementia and its impact on the health status of older people. As dementia is a significant global health problem which also has social and economic impacts this document highlights the importance of monitoring dementia in the region. The document evidences that dementia is one of the main contributors to dependence and disability in older people in Latin America and the Caribbean and, although its prevalence and incidence increase exponentially with age, it is not part of normal aging. Alzheimer’s disease is the most common dementia, and there is no cure for this condition, but with timely diagnosis is possible to ameliorate symptoms. It is important to assess what are the needs of people leaving with dementia and their families and to integrate dementia risk reduction strategies in pre-existing strategies for other non-communicable diseases. As shown in the report, despite the huge burden dementia is still underdiagnosed, and it is fundamental to better monitor its prevalence, incidence and the different societal impact that dementia can have. For that, it is crucial to promote the use of harmonized methodologies to address this information in a broader number of studies and countries in the region. This can contribute to the generation of direct actions to decrease dementia risk and lead to healthier lives for people with dementia and their families.

Background: Investing in the health workforce is key to achieving the health-related Sustainable Development Goals. However, achieving these Goals requires addressing a projected global shortage of 18 million health workers (mostly in low- and middle-income countries). Within that context, in 2016,
...
the World Health Assembly adopted the WHO Global Strategy on Human Resources for Health: Workforce 2030. In the Strategy, the role of official development assistance to support the health workforce is an area of interest. The objective of this study is to examine progress on implementing the Global Strategy by updating previous analyses that estimated and examined official development assistance targeted towards human resources for health. Methods: We leveraged data from IHME’s Development Assistance for Health database, COVID development assistance database and the OECD’s Creditor Reporting System online database. We utilized an updated keyword list to identify the relevant human resources for health-related activities from the project databases. When possible, we also estimated the fraction of human resources for health projects that considered and/or focused on gender as a key factor. We described trends, examined changes in the availability of human resources for health-related development assistance since the adoption of the Global Strategy and compared disease burden and availability of donor resources.

This country cooperation strategy (CCS) outlines how the World Health Organization (WHO) will work with the Lao People’s Democratic Republic over the next five years (2024–2028), supporting the implementation of the five-year health sector development plans and the Health Sector Reform Strategy
...
2021–2030 to attain the Sustainable Development Goals (SDGs) by 2030.
The Lao People’s Democratic Republic experienced substantial economic growth in the 30 years prior to the coronavirus disease (COVID-19) pandemic, contributing to reduced poverty and significant progress toward the SDGs. However, the COVID-19 pandemic brought this development to a halt. It was anticipated that the COVID-19 recovery and the tremendous population growth in recent years would provide opportunities for a shift toward more sustainable and inclusive development in the years ahead. In 2023, however, the contrary was the case. Rural residents, including many ethnic minorities, continued to face marginalization because of limited access to education, health care and economic opportunities.
Despite the challenges of COVID-19 and other disease outbreaks, the country has made significant improvements in health. Nonetheless, progress has been uneven and not everyone has benefited from these achievements. In the mountainous region, many people lack access to quality health care because of the unequal distribution of well-trained health-care workers. Preventable deaths due to poor-quality health care for children and newborns, infants and mothers remain a concern, as do communicable diseases such as sexually transmitted infections and tuberculosis. The increasing burden of noncommunicable diseases and the health impact of worsening climate change further heighten the need for strengthened and resilient health systems, which are at risk due to an underfunded health sector and weak economy.
This CCS aims to address remaining and future challenges as well as health needs while creating an impact that is sustainable. It identifies three strategic priorities and nine deliverables (Table 1) to support the attainment of the national vision of Health for all by all, as articulated in the 9th Health Sector Development Plan 2021–2025. It contributes to the country’s goals to achieve universal health coverage, graduate from least developed country status by 2026 and attain SDGs by 2030.

Background: Cardiovascular disease (CVD), mainly heart attack and stroke, is the
leading cause of premature mortality in low and middle income countries (LMICs).
Identifying and managing individuals at high risk of CVD is an important strategy to prevent and control CVD, in addition to multisector
...
al population-based interventions to reduce CVD risk factors in the entire population.
Methods: We describe key public health considerations in identifying and managing individuals at high risk of CVD in LMICs.
Results: A main objective of any strategy to identify individuals at high CVD risk is to maximize the number of CVD events averted while minimizing the numbers of
individuals needing treatment. Scores estimating the total risk of CVD (e.g. ten-year risk of fatal and non-fatal CVD) are available for LMICs, and are based on the main CVD risk factors (history of CVD, age, sex, tobacco use, blood pressure, blood cholesterol and diabetes status). Opportunistic screening of CVD risk factors enables identification of persons with high CVD risk, but this strategy can be widely applied in low resource settings only if cost effective interventions are used (e.g. the WHO Package of Essential NCD interventions for primary health care in low resource settings package) and if treatment (generally for years) can be sustained, including continued availability ofaffordable medications and funding mechanisms that allow people to purchase medications without impoverishing them (e.g. universal access to health care). Thisalso emphasises the need to re-orient health systems in LMICs towards chronic diseases management.
Conclusion: The large burden of CVD in LMICs and the fact that persons with high
CVD can be identified and managed along cost-effective interventions mean that
health systems need to be structured in a way that encourages patient registration, opportunistic screening of CVD risk factors, efficient procedures for the management of chronic conditions (e.g. task sharing) and provision of affordable treatment for those with high CVD risk. The focus needs to be in primary care because that is where most of the population can access health care and because CVD programmes can be run effectively at this level.

Many features of the environment have been found to exert an important influence on cardiovascular disease (CVD) risk, progression, and severity. Changes in the environment due to migration to different geographic locations, modifications in lifestyle choices, and shifts in social policies and cultu
...
ral practices alter CVD risk, even in the absence of genetic changes. Nevertheless, the cumulative impact of the environment on CVD risk has been difficult to assess
and the mechanisms by which some environment factors influence CVD remain obscure. Human environments are complex; and their natural, social and personal domains are highly variable due to diversity in human ecosystems, evolutionary histories, social structures, and individual choices. Accumulating evidence supports the notion that ecological features such as the diurnal cycles of
light and day, sunlight exposure, seasons, and geographic characteristics of the natural environment such altitude, latitude and greenspaces are important determinants of cardiovascular health and CVD risk. In highly developed societies, the influence of the natural environment is moderated by the physical characteristics of the social environments such as the built environment
and pollution, as well as by socioeconomic status and social networks. These attributes of the
social environment shape lifestyle choices that significantly modify CVD risk. An understanding
of how different domains of the environment, individually and collectively, affect CVD risk could
lead to a better appraisal of CVD, and aid in the development of new preventive and therapeutic
strategies to limit the increasingly high global burden of heart disease and stroke.

Nations adopted the 2030 Agenda for Sustainable Development. It sets out 17 Goals, which include 169 targets. These wide-ranging and ambitious Goals interconnect. SDG 3 is to ensure healthy lives and promote well-being for all at all ages. It has 13 targets measured through 26 indicators. However, a person’s health and well-being are affected not only by disease and treatment, but also by social and economic factors such as housing, poverty and education. Health targets can therefore also be found across the other SDGs. This fact sheet shows how alcohol consumption undermines commitments to achieve 13 of the 17 SDGs, impacting on a range of health-related indicators, such as child health, infectious diseases and road injuries as well as much broader range of indicators related to economic and social development, environment and equality. The inclusion of a specific target on harmful use of alcohol (SDG 3.5: strengthen the prevention and treatment of substance abuse, including narcotic drug abuse and harmful use of alcohol) into the SDGs demonstrates the key role of alcohol within the global development agenda. The factsheet highlights positive examples of Member States’ experiences. It provides a short overview of the most cost-effective and feasible policy recommendations to reduce alcohol consumption and alcohol-attributable burden in the WHO European Region, in line with the European Action Plan to Reduce the Harmful Use of Alcohol. It also suggests some important resources for Member States. This factsheet was launched as part of the European Awareness Week on Alcohol Related Harm 2020.

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.

rly resourced settings. Several epidemiological studies in the last decades have shown significant variability in the prevalence of asthma globally, but generally a marked increase in LMICs resulting in significant mor- bidity and mortality. Poverty, air pollution, climate change, exposure to indoor allergens, urbanization and diet are some of the factors that contribute to inadequate control and poor outcomes in developing countries. Although asthma guidelines have been developed to raise awareness and improve asthma diagnosis and treatment, problems with underdiagnosis and undertreatment are still common. In addition, important social, financial, cultural and healthcare barriers are common obstacles in LMICs in achieving control. Given the high burden of asthma in these countries, adaptation and implementation of national asthma guidelines tailored to local needs should be a public health priority. Governmental commitment, education, better health system infrastructure, access to care and effective asthma medications are the cornerstone of achieving success.

In Latin America and the Caribbean (LAC), one maternal death was registered every hour in 2020.

In addition to indicating a wors

ening of health outcomes, these figures also signal a deepening of inequalities, representing thousands of individual, unacceptable tragedies that in most cases could have been preventable. Maternal death is the result of a multifactorial process in which structural elements such as the economic system, environmental conditions, and culture interact. Other factors related to social inequality are also present, such as racism, poverty, gender inequality, and lack of access to the education system. The current situation calls for urgent mobilization of the health systems of LAC countries in order to strengthen efforts to combat maternal mortality, especially in countries that are still far from achieving the SHAA2030 regional target. For this reason, a preventive, health-promoting, life-course-based approach is needed, with models of care centered on women, families, and the community Scientific evidence shows that health systems with a solid foundation in primary health care (PHC) achieve better outcomes, greater equity, and reduced health expenditures. To address this, PAHO proposes a strategy, aimed primarily at women who are in the most vulnerable situation, who are the ones who represent the greatest burden of maternal mortality, to accelerate the reduction of maternal mortality in the Region of the Americas, based on the expansion and strengthening of PHC.

k factors for asthma in adolescents in an LMIC.
Methods
A cross-sectional survey using the Global Asthma Network written and video questionnaires was conducted in adolescents aged 13 and 14 from randomly selected schools in Durban, South Africa, between May 2019 and June 2021.
Results
A total of 3957 adolescents (51.9% female) were included. The prevalence of lifetime, current and severe asthma was 24.6%, 13.7% and 9.1%, respectively. Of those with current and severe asthma symptoms; 38.9% (n=211/543) and 40.7% (n=147/361) had doctor-diagnosed asthma; of these, 72.0% (n=152/211) and 70.7% (n=104/147), respectively, reported using inhaled medication in the last 12 months. Short-acting beta agonists (80.4%) were more commonly used than inhaled corticosteroids (13.7%). Severe asthma was associated with: fee-paying school quintile (adjusted OR (CI)): 1.78 (1.27 to 2.48), overweight (1.60 (1.15 to 2.22)), exposure to traffic pollution (1.42 (1.11 to 1.82)), tobacco smoking (2.06 (1.15 to 3.68)), rhinoconjunctivitis (3.62 (2.80 to 4.67)) and eczema (2.24 (1.59 to 3.14)), all p<0.01.
Conclusion
Asthma prevalence in this population (13.7%) is higher than the global average (10.4%). Although common, severe asthma symptoms are underdiagnosed and associated with atopy, environmental and lifestyle factors. Equitable access to affordable essential controller inhaled medicines addressing the disproportionate burden of asthma is needed in this setting.
