The dual burden of malnutrition and its associated factors among mother-child pairs at the household level in Ethiopia: An urgent public health issue demanding sector-wide collaboration.

The coexistence of under-nutrition and over-nutrition in developing countries like Ethiopia results in the "mother-child pair double burden of malnutrition," with children experiencing either stunting, wasting or underweight while mothers face overweight or obesity. This poses a major public health challenge, prompting global health organizations to prioritize the issue and urge governments to act quickly. Despite this, there is a lack of research in Ethiopia on the double burden of malnutrition among mother-child pairs at the household level and the factors that worsen it. To assess the magnitude of double burden of malnutrition and its associated factors among mother-child pair at household level in East Ethiopia, 2022. A community-based cross-sectional study was conducted in East Ethiopia from April 15 to June 11, 2022. Multi-stage sampling was used, and data were collected through structured interviews. Child nutrition indicators were processed using WHO Anthro software. Binary logistic regression analysis was performed, calculating both crude and adjusted odds ratios to assess associations. Variables with a P value <0.05 in multivariable analysis were deemed statistically significant. The study revealed that coexisting malnutrition rates for (OM/SC), (OM/WC), and (OM/UC) were 8.5%, 7.0%, and 7.9% respectively. The double burden of malnutrition among mother-child pairs was found to be 12.3% [95% CI: 10.7, 13.7]. Marital status (divorced) [AOR = 1.80; 95% CI: 1.15, 2.82], child birth order (fourth or above) [AOD = 1.88; 95% CI:1.08, 3.26], number of under-five children in the household (five or more under-five children) [AOR = 1.58; 95% CI: 1.04, 2.39], poor maternal and child dietary diversity score [AOR = 2.76; 95% CI: 1.71, 4.45] and [AOR = 8.66; 95% CI: 4.85, 15.44], respectively, household food security status (food insecurity) [AOR = 3.68; 95% CI: 2.36, 5.75], and maternal stature (short stature) [AOR = 2.39; 95% CI: 1.65,3.45] were factors significantly associated with this burden. The study emphasized the double burden of malnutrition affecting both mothers and children, a major public health concern in the area. Early-life nutrition is vital in preventing childhood under nutrition and adult obesity, leading to this dual burden. Breaking the cycle of malnutrition across generations is crucial. Policy makers should prioritize improving child nutrition and maternal health, stressing early-life nutrition to address the mother-child double burden of malnutrition.

Malnutrition: A Longstanding Challenge in India

Abstract: According to the World Health Organization, “malnutrition is the “deficiencies, excesses, or imbalances in a person’s intake of energy and/or nutrients”. Indian population has the highest rate of adolescent malnutrition. Deficiency, Illness, Small level of education, and a range of other factors contribute to India's malnutrition crisis. Undernutrition, micronutrient deficiency conditions, and overnutrition are all forms of malnutrition. A malnourished always lags in every aspect of life which will eventually affect the productivity of the country. In the 2023 Global Hunger Index, India is positioned at 111th among 125 countries, reflecting a serious level of hunger with a score of 28.7. India is grappling with a substantial population affected by anemia, malnutrition, and obesity. Other than this Indian population is also affected by several other micronutrient deficiencies. The present article provides an overview of the triple burden of malnutrition in India by applying the literature review method and the data were collected from online sources such as government survey reports, articles, and publications related to nutrition, healthcare status, healthcare indicators, nutritional indicators, and healthcare survey reports, etc. A brief introduction of the strategies followed by the Government as well as global health organisations to combat the issue is also discussed.

Clearing the Air to Address Pollution's Cardiovascular Health Crisis.

Air pollution is a critical global health issue that significantly impacts cardiovascular health. The air pollutant PM2.5 (particulate matter with a diameter of 2.5 micrometres or less) has been positioned as a leading environmental risk factor for morbidity and mortality, especially from cardiovascular diseases (CVDs). Using data from the World Health Organization (WHO), Global Health Observatory, and the United Nations Environment Programme, we explored global trends in air pollution, with a focus on PM2.5 levels, the implications for cardiovascular health, and the policy measures aimed at reducing their impact. Despite progress in reducing pollution levels in high-income countries, global trends show a limited annual reduction in PM2.5 concentration. The analysis highlights disparities between regions, with low- and middle-income countries bearing the brunt of air pollution-related CVDs. In 2019 alone, ambient air pollution was responsible for approximately 4.2 million deaths worldwide. Of these, 70% were caused by CVDs, with approximately 1.9 million deaths from ischemic heart disease and 900,000 deaths from stroke. Policy gaps remain a challenge, with many countries lacking adequate legally binding air quality standards. We recommend the adoption of WHO air quality guidelines, enhanced monitoring of air pollution levels, and increased investment in interdisciplinary research to understand the full scope of air pollution's effects on cardiovascular health. Addressing the global cardiovascular crisis linked to air pollution will require coordinated efforts from policymakers, healthcare systems, and global health organisations.

Effects of screening coverage and screening quality assurance on cervical cancer mortality: Implication for integrated framework to monitor global implementation of cervical cancer screening programmes.

Cervical cancer is a global health threat and a manifestation of inequality, and screening is an effective intervention. However, little is known about how screening coverage and quality assurance, influence cervical cancer mortality. We aimed to investigate the association between screening coverage, screening quality assurance and cervical cancer mortality among women from countries at different developmental levels. We obtained data on age-standardised mortality from cervical cancer from the GLOBOCAN 2020 database; coverage of cervical cancer screening from World Health Organization (WHO) Global Health Observatory; and cervical screening programme settings and quality assurance from the Cancer Screening in Five Continents (CanScreen5) database. We assessed the dependency of cervical cancer age-standardised mortality on screening coverage and quality assurance by simple and multiple regression models. We also used linear regression models to identify factors that improved the screening coverage. The study included data from 53 countries. Reduced mortality was associated with increased screening programme quality assurance in 22 high-development countries. In 31 low-development countries, screening coverage in women aged 30-49 years was inversely associated with cervical cancer mortality. Political commitment (documentation of the cervical cancer screening policy as law) and financial support (treatment services provided free of charge) positively associated with screening coverage. Screening programmes need strengthening commensurate with local resources and context. Priority should be given to improving screening coverage through stronger political commitment and financial support in low-development countries, and to ensuring good performance at all levels in high-development countries.

Holy grail or convenient excuse? Stakeholder perspectives on the role of health system strengthening evaluation in global health resource allocation

BackgroundThe role of evaluation evidence in guiding health systems strengthening (HSS) investments at the global-level remains contested. A lack of rigorous impact evaluations is viewed by some as an obstacle to scaling resources. However, others suggest that power dynamics and knowledge hierarchies continue to shape perceptions of rigor and acceptability in HSS evaluations. This debate has had major implications on HSS resource allocation in global-level funding decisions. Yet, few studies have examined the relationship between HSS evaluation evidence and prioritization of HSS. In this paper, we explore the perspectives of key global health stakeholders, specifically around the nature of evidence sought regarding HSS and its potential impact on prioritization, the challenges in securing such evidence, and the drivers of intra- and inter-organizational divergences. We conducted a stakeholder analysis, drawing on 25 interviews with senior representatives of major global health organizations, and utilized inductive approaches to data analysis to develop themes.ResultsOur analysis suggests an intractable challenge at the heart of the relationship between HSS evaluations and prioritization. A lack of evidence was used as a reason for limited investments by some respondents, citing their belief that HSS was an unproven and potentially risky investment which is driven by the philosophy of HSS advocates rather than evidence. The same respondents also noted that the ‘holy grail’ of evaluation evidence that they sought would be rigorous studies that assess the impact of investments on health outcomes and financial accountability, and believed that methodological innovations to deliver this have not occurred. Conversely, others held HSS as a cross-cutting principle across global health investment decisions, and felt that the type of evidence sought by some funders is unachievable and not necessary – an ‘elusive quest’ – given methodological challenges in establishing causality and attribution. In their view, evidence would not change perspectives in favor of HSS investments, and evidence gaps were used as a ‘convenient excuse’. Respondents raised additional concerns regarding the design, dissemination and translation of HSS evaluation evidence.ConclusionsOngoing debates about the need for stronger evidence on HSS are often conducted at cross-purposes. Acknowledging and navigating these differing perspectives on HSS evaluation may help break the gridlock and find a more productive way forward.

Modern Classification of Respiratory Diseases: Innovations in the International Classification of Diseases of the 11th Revision

A comprehensive analysis has been performed on the innovations in the classification of respiratory diseases introduced in ICD-11, comparing it with the previous ICD-10 version. This analysis underscores the critical importance of implementing a more detailed and systematic approach to categorizing diseases of the respiratory system. The enhancements found in ICD-11 have been proven to open up new opportunities for the timely and high-quality provision of medical and pharmaceutical care. This is particularly significant for patients suffering from various injuries, including those resulting from traffic accidents, participation in combat operations, and thoracic injuries. The updated classification system in ICD-11 allows for more precise diagnosis and treatment plans, which is essential for improving patient outcomes. By providing a more granular level of detail in disease categorization, healthcare professionals can better understand the nuances of respiratory conditions. This leads to more effective communication among doctors, pharmacists, and patients, thereby improving the legal and professional relationships within the healthcare system. Integrating the ICD-11 classification into educational and training programs is essential for advancing the qualifications of specialists. By incorporating it into curricula and professional development programs, medical practitioners can stay abreast of the latest advancements in disease classification and patient care. This integration is also vital for eliminating medical errors, as a more detailed classification system reduces the likelihood of misdiagnosis and improper treatment. Furthermore, adopting ICD-11 supports the ongoing development of the healthcare sector in Ukraine. It aligns the country's medical practices with international standards, facilitating better collaboration with global health organizations. This alignment is crucial for enhancing the overall quality of healthcare services provided to the population. In conclusion, the transition to ICD-11 represents a significant advancement in the classification of respiratory diseases. Its implementation is imperative for improving medical and pharmaceutical care, enhancing specialist training programs, and strengthening the doctor-pharmacist-patient relationship. Embracing this updated classification system will not only reduce medical errors but also contribute to the further development of Ukraine's healthcare sector.

In vitro activity assessment of cefiderocol against Enterobacterales, Pseudomonas aeruginosa, and Acinetobacter spp., including β-lactam nonsusceptible molecularly characterized isolates, collected from 2020 to 2021 in the United States and European hospitals.

This study reports the activity of cefiderocol against Enterobacterales, Pseudomonas aeruginosa, and Acinetobacter spp. isolates collected from the United States and Europe, including Israel and Turkey, from 2020 to 2021. Among Enterobacterales, 2.8% were carbapenem nonsusceptible (CNSE); cefiderocol inhibited 96.6%/85.1% [Clinical Laboratory Standards Institute (CLSI)/European Committee on Antimicrobial Susceptibility Testing (EUCAST) breakpoints] of these isolates. Imipenem-relebactam, meropenem-vaborbactam, and ceftazidime-avibactam displayed susceptibilities lower than cefiderocol against CNSE isolates (67.4-84.6% susceptible, CLSI). Cefiderocol was the only agent active against CNSE isolates carrying metallo-β-lactamase (MBL) carbapenemase or multiple carbapenemase genes (84.6%-92.3% susceptible, CLSI). Approximately 18% of carbapenem-susceptible Escherichia coli, Klebsiella pneumoniae, and Proteus mirabilis carried extended-spectrum-β-lactamases and/or plasmid-borne AmpC-encoding genes; cefiderocol inhibited 99.8%-100.0% (CLSI) of these genotypic groups. Multi-drug resistance (MDR) phenotypes were observed in 16.9% and 52.5% of P. aeruginosa and A. baumannii-calcoaceticus isolates, respectively. Carbapenemase genes were rare (4.9%) among cephalosporin and/or carbapenem nonsusceptible P. aeruginosa, compared to 87.6% carriage in A. baumannii-calcoaceticus, respectively. Against the MDR and carbapenemase-carrying P. aeruginosa and A. baumannii-calcoaceticus subsets, cefiderocol was active against 98.6%/98.7% and 97.1%/97.4% (CLSI), respectively. Only 69 isolates (0.3%) across all species groups were identified as cefiderocol nonsusceptible per CLSI criteria (>4 mg/L). Cefiderocol was the most active agent in vitro against Enterobacterales, P. aeruginosa, and Acinetobacter spp., with uniform activity against all phenotypic- and genotypic-resistant subsets. Coupled with the low incidence of nonsusceptibility observed across species groups, these results demonstrate cefiderocol as an important option for treating infections caused by pathogens with diverse mechanisms of resistance in US and European hospitals.IMPORTANCEThe worldwide spread of multi-drug-resistant Pseudomonas aeruginosa and carbapenem-resistant Enterobacterales and Acinetobacter spp. poses a serious challenge in healthcare settings as infections caused by these organisms are commonly refractory to many frontline therapeutic agents. Multiple global health organizations highlighted these pathogens as critical priorities for new antibiotic development, thus necessitating continued surveillance of the activities of currently available antimicrobial agents and circulating mechanisms of resistance. To meet this need, this study phenotypically and genotypically characterized priority Gram-negative pathogens collected from patients in US and European hospitals to examine the activity of cefiderocol and other currently available treatment options, including carbapenems and β-lactam-β-lactamase inhibitor combinations. The results presented here provide a detailed perspective to healthcare practitioners of cefiderocol's broad applicability, manifested in high activity and low nonsusceptibility rates, across phenotypic and genotypic organism groups relative to other agents and further support its use against the most intransigent infections.

Big Data in Epidemiology: Brave New World?

Epidemiology is experiencing a significant shift toward the utilization of big data for health monitoring and decision-making. This article discusses the recent example of the World Health Organization (WHO) global oral health status report and regional summaries, which faced criticisms due to its reliance on big data from the Global Burden of Disease (GBD) study. We address the arguments for and against the use of big data in epidemiology and provide an assessment of the value and limitations of big data epidemiology. Moreover, we provide recommendations as to how the oral health community should reconcile traditional epidemiologic approaches with big data and advanced data analytics. This Perspective article highlights the challenges of the current epidemiologic landscape, the potential of big data, and the need for a balanced approach to data utilization in epidemiology.

Intrauterine device use in adolescence: a narrative review.

Contraceptive use in adolescence remains a challenging issue. Adolescents are at high risk of unintended pregnancies and sexual transmitted infections. During the past few decades intrauterine devices are recommended from global health organization, including the American Academy of Pediatrics, American College of Obstetricians and Gynecologists and World Health Organization as a method of contraception for adolescents. Intrauterine devices are part of the long-acting reversible contraceptives (LARCs) and include the copper bearing device (CU-IUD) and the levonorgestrel intrauterine system (LNG-IUS). IUDs are a safe and effective contraceptive method for adolescents with a failure rate less than 1%. Their use is not limited only in contraception. LNG-IUS 52 mg is approved for treating heavy menstrual bleeding and protection from endometrial hyperplasia in women receiving hormone replacement therapy. It can also be an effective tool in the management of dysmenorrhea, while CU-IUD can provide emergency contraception. Nevertheless, IUDs remain underutilized in this group of population. Adolescents' lack of proper education about contraception and sexual behavior creates myths and misconceptions about the possible side effects and the suitability of IUDs in this age group. Furthermore, health care providers remain skeptical and hesitate to suggest IUDs to adolescents. Other barriers including high cost, concern about confidentiality and difficulties in access contribute to its limited use. It is of high importance to eliminate barriers and offer more accessible contraceptive services to adolescents.

Infodemic, Ignorance, or Imagination? The Problem of Misinformation in Health Emergencies

Abstract In understanding and responding to the problem of misinformation during global health emergencies, health experts and organizations such as the WHO have relied on the concept of the “infodemic,” or the idea that there is such an overabundance of information that ascertaining trustworthy sources and reliable guidance is difficult. Is this the best way to understand the problem of misinformation, however? A large and multidisciplinary literature has argued that such an approach misses the important role of individual psychological factors and societal “mega-trends” such as hyperpolarization, structural shifts in the media, and public mistrust in elites. This article argues that such contributions are important in understanding the multifaceted problem of misinformation but may miss another, equally important component: the politics of emergency. Specifically, the prominent role of speculation during moments of emergency—the need to respond to “what ifs” rather than just “what is”—provides a conducive context for misinformation, facilitating its production and spread while also problematizing efforts to correct it. The article illuminates this relationship through a discourse analysis of prominent misinformation claims during the US responses to Ebola in 2014 and COVID-19 in 2020.

Guidance for the occupational medicine service regarding the prevention of hepatitis C and HIV infection in Poland

The set up of new healthcare models by taking into account diagnosis and health education of the viral infection, aims to achieve the goals of the World Health Organization Global Health Sector Strategy on viral diseases for 2022-2030. In comparison to Europe, Poland is ranked among countries with an moderate prevalence of hepatitis B and C virus (HBV and HCV), also human immunodeficiency virus (HIV). An additional challenge is the changing epidemiological situation due to the impact of immigrants, resulting mainly from the war in Ukraine. The article presents current guidance for HCV and HIV diagnosis and presents the role of occupational health service (OHS) for primary and secondary prevention of the infectious diseases. It was considered to expand the scope of periodic examinations to include diagnosis of HBV, HCV and HIV infections among health care workers, who have not had it performed so far. In the case of abnormal level of alanine aminotransferase (ALT), aspartate aminotransferase (AST) or γ-glutamyl transpeptidase (GGT) found during routine pre-employment or periodic examinations for specific occupational exposures and it is considered crucial to implement further measures to exclude or confirm HBV or HCV infection, with indications for further management in primary care, and followed by subsequent periodic examinations. The need to pay attention to any symptoms that may indicate HBV, HCV and/or HIV infection, to perform additional diagnostic tests (e.g., point of care), and to determine the next steps in case of positive result was indicated. It emphasized the need to tailor the delivery of information to the patient, including taking care to ensure that immigrants' workers understand the next steps. It was recommended that the OHS conduct educational activities to raise health awareness of HIV, HCV, HBV infections, both through health policy programs as well as through broader activities in cooperation with the employer.

The interplay between mobilome and resistome in Staphylococcus aureus.

Antibiotic resistance genes (ARGs) in Staphylococcus aureus can disseminate vertically through successful clones, but also horizontally through the transfer of genes conveyed by mobile genetic elements (MGEs). Even though underexplored, MGE/ARG associations in S. aureus favor the emergence of multidrug-resistant clones, which are challenging therapeutic success in both human and animal health. This study investigated the interplay between the mobilome and the resistome of more than 10,000 S. aureus genomes from human and animal origin. The analysis revealed a remarkable diversity of MGEs and ARGs, with plasmids and transposons being the main carriers of ARGs. Numerous MGE/ARG associations were identified, suggesting that MGEs play a critical role in the dissemination of resistance. A high degree of similarity was observed in MGE/ARG associations between human and animal isolates, highlighting the potential for unrestricted spread of ARGs between hosts. Our results showed that in parallel to clonal expansion, MGEs and their associated ARGs can spread across different strain types sequence types (STs), favoring the evolution of these clones and their adaptation in selective environments. The high variability of MGE/ARG associations within individual STs and their spread across several STs highlight the crucial role of MGEs in shaping the S. aureus resistome. Overall, this study provides valuable insights into the complex interplay between MGEs and ARGs in S. aureus, emphasizing the need to elucidate the mechanisms governing the epidemic success of MGEs, particularly those implicated in ARG transfer.IMPORTANCEThe research presented in this article highlights the importance of understanding the interactions between mobile genetic elements (MGEs) and antibiotic resistance genes (ARGs) carried by Staphylococcus aureus, a versatile bacterium that can be both a harmless commensal and a dangerous pathogen for humans and animals. S. aureus has a great capacity to acquire and disseminate ARGs, enabling efficient adaption to various environmental or clinical conditions. By analyzing a large data set of S. aureus genomes, we highlighted the substantial role of MGEs, particularly plasmids and transposons, in disseminating ARGs within and between S. aureus populations, bypassing host barriers. Given that multidrug-resistant S. aureus strains are classified as a high-priority pathogen by global health organizations, this knowledge is crucial for understanding the complex dynamics of transmission of antibiotic resistance in this species.

Innovative External Cranial Devices for Protecting a Craniectomy Site: A Scoping Review on Noninvasive Approaches for Patients Awaiting Cranioplasty.

Decompressive craniectomy (DC) is a commonly performed procedure to alleviate high intracranial pressure. To enhance patient quality of life and minimize complications after DC in patients awaiting cranioplasty (CP), multidisciplinary teams have designed and implemented external protective prototypes, including 3-dimensional printing and plaster models, whenever feasible. The aim of this scoping review was to assess the evidence available on innovative external cranial devices that protect the craniectomy site for patients who have undergone DC while awaiting CP in high-income countries and low- and middle-income countries. This scoping review was conducted following the methodology outlined by the Joanna Briggs Institute. Searches were performed in databases such as MEDLINE, Embase, Web of Science, Scielo, Scopus, and World Health Organization Global Health Index Medicus. Patent documents were also searched in Espacenet, Google Patents, and World Intellectual Property Organization. This scoping review included external protective devices for adult patients who underwent DC and CP, while invasive devices were excluded. A total of 9 documents described external cranial devices, with 7 of them led by researchers from high-income countries, including the United States (n = 4), Singapore (n = 1), the United Kingdom (n = 1), and Hong Kong SAR, China (n = 1). Among these devices, 77.7% (n = 7) were created using 3-dimensional printing, while 22.3% (n = 2) were developed through plaster hand modeling. The individual study results were summarized. Sustainable Development Goal (SDG) 3, SDG 9, and SDG 10 play a crucial role in the advancement of innovative strategies to ensure access to essential neurosurgical care, reduce global disparities in treatment outcomes, mitigate postoperative complications, and provide life-saving interventions. This scoping review provides fundamental evidence for multidisciplinary teams involved in designing noninvasive innovations to minimize the risks associated with post-DC complications. It is anticipated that more cost-effective models, particularly in low- and middle-income countries, can be implemented based on the findings of this review.

Sex-related inequalities in current cigarette smoking among adolescents in Africa

IntroductionRisky behaviours, including tobacco use, are highly prevalent among adolescents worldwide. Although these behaviours are largely influenced by various sociodemographic factors, including sex, there is a paucity of regionally representative literature on the sex-related inequalities in cigarette smoking among adolescents in Africa. This study examined the sex-based disparities in current cigarette smoking among adolescents aged 13–15 years in Africa.MethodsThe present study employed a secondary analysis of nationally representative data on 45 African countries obtained from the Global Youth Tobacco Survey, accessible through the World Health Organization (WHO) Global Health Observatory. We used the online version of the WHO Health Equity Assessment Toolkit (HEAT) to generate the results.ResultsThe prevalence of current cigarette smoking among the adolescents surveyed ranged from 1.6% in Eritrea to 10.4% in Mali among the low-income countries, from 1.3% in Tanzania to 13.1% in Mauritania among the lower-middle-income countries, from 5.2% in Gabon to 15.3% in Mauritius among the upper-middle-income countries, and 14.7% in Seychelles, the only high-income country in the study. The absolute summary measure (D) showed diverse sex-related disparities in the burden of current cigarette smoking among adolescents across the sub-regions. In all countries surveyed, the prevalence of cigarette smoking was higher among male adolescents compared to females, except in Liberia and Mozambique, where female adolescents bore a more significant burden than their male counterparts. Furthermore, male adolescents were more burdened with high cigarette smoking prevalence than females in low-income countries such as Mali, Madagascar, Guinea, Burkina Faso, and The Gambia, where such disparities were most pronounced. Meanwhile, we found less disparity in the burden of cigarette smoking between male and female adolescents in most of the lower and upper-middle-income countries surveyed.ConclusionThis study sheds light on the sex-based inequalities in the prevalence of current cigarette smoking among adolescents in Africa. In contrast to female adolescents, male adolescents bear a greater burden of current cigarette smoking. The burden of cigarette smoking is most pronounced in low-income countries such as Mali, Madagascar, Guinea, Burkina Faso, and The Gambia. Conversely, in most of the lower and upper-middle-income countries surveyed, the burdens of current cigarette smoking among male and female adolescents were found to be less disparate. Consequently, cigarette smoking prevention programmes and strategies must be implemented in all African nations. There is also the need to intensify interventions aimed at altering the smoking behaviour of male adolescents. Policymakers can develop and implement evidence-based interventions to address the burden of cigarette smoking among the adolescents. Finally, existing policies and programmes addressing adolescents' cigarette smoking should be re-assessed and strengthened to achieve their objectives.

The Role of Climate and Environmental Factors in Malaria Transmission in Nigeria: Challenges and Prospects

Malaria remained a major public health challenge in Nigeria, contributing to high rates of morbidity and mortality, particularly among vulnerable groups like children and pregnant women. The transmission of malaria is heavily influenced by climate and environmental factors such as temperature, rainfall, humidity, land use, and ecological changes, which affect the lifecycle of the malaria parasite (Plasmodium spp.) and its mosquito vector (Anopheles species). This review explored how these climatic and environmental factors impacted malaria transmission dynamics across Nigeria’s diverse regions. It also examined the challenges posed by climate variability, inadequate infrastructure, and the emergence of resistance to insecticides and antimalarials, while highlighting the potential of integrated vector management, climate-smart strategies, and community engagement in mitigating these impacts. The methodology used involved a comprehensive review and synthesis of relevant literature and data sources, including peer-reviewed journals, government reports, and global health organization publications. Understanding the intricate relationships between these factors and malaria transmission was crucial for developing adaptive strategies to reduce the burden of malaria in Nigeria, particularly in the face of ongoing environmental and climatic changes. Keywords: Malaria Transmission, Climate Factors, Environmental Factors, Nigeria, Vector Control.

Strengthening health systems during non-pandemic period: Toward universal health coverage in the pandemic agreement.

Reflecting the experiences of the COVID-19 pandemic, the global response was reviewed by the Independent Review Panel for Pandemic Preparedness and Response. Based on the panel reports, the World Health Organization (WHO) member states decided to establish the intergovernmental negotiating body for drafting a WHO convention, agreement or other international instrument on pandemic prevention, preparedness and response, aiming for approval at the 77th World Health Assembly in 2024 (May 27- June 1). Amidst this process, the National Center for Global Health and Medicine, Japan (NCGM), as a global health organization focusing on health system strengthening in low- and middle-income countries, from the perspective of Universal Health Coverage (UHC), provided technical inputs to the representatives of the Japanese government. This paper summarizes crucial aspects of the NCGM inputs, including maintaining essential health services delivery during a pandemic, responding to evolving demand of health workforce, and ensuring the equitable distribution of pandemic products. These aspects can contribute to not only strengthening health crisis response and preparedness, but also achieving UHC. Therefore, the concerted efforts focusing on UHC and health crisis could yield synergistic effects. In addition, another aspect stresses the importance of social protection systems beyond health sector to reach vulnerable populations experiencing hardships during the COVID-19 pandemic. Since the whole-of-government approach including social policies is covered in the draft pandemic agreement, it is hoped that the upcoming pandemic agreement will trigger each member state to expand the scope of health crisis management beyond the health sector.

Meat products in human nutrition and health – About hazards and risks

Meat processing has a long history and involves a wide and ever-increasing range of chemical and physical processes, resulting in a heterogeneous food category with a wide variability in nutritional value. Despite the known benefits of meat consumption, observational epidemiological studies have shown associations between consumption of red and processed meat - but not white meat - and several non-communicable diseases, with higher relative risks for processed meat compared to unprocessed red meat. This has led global and regional nutrition and health organisations to recommend reducing consumption of unprocessed red meat and avoiding processed meat. A plethora of potentially implicated hazardous compounds present in meat or formed during processing or gastrointestinal digestion have been reported in the literature. However, our mechanistic understanding of the impact of meat consumption on human health is still very incomplete and is complicated by the simultaneous occurrence of multiple hazards and interactions with other food compounds and host factors. This narrative review briefly discusses hazards, risks and their assessment in the context of dietary guidelines. It is argued that more mechanistic studies of the interactive effects of meat products with other foods and food compounds in different dietary contexts are needed to refine and increase the evidence base for dietary guidelines. Importantly, the great diversity in the composition and degree of processing of processed meats should be better understood in terms of their impact on human health in order to develop a more nuanced approach to dietary guidelines for this food category.

Lipidomics unveils changes in oxidised lipids in human breast milk by high‐pressure processing

SummaryHuman breast milk is a complex fluid rich in bioactive molecules crucial for infant growth and development. Global health organisations recommend exclusive breastfeeding to optimise infant health. In cases where maternal milk is unavailable, donor breast milk from human milk banks (HMBs) serves as an essential alternative. Currently, human breast milk preservation relies on Holder pasteurisation (HoP), which, while effective at pathogen inactivation, can compromise breast milk's nutritional and biological properties. High‐pressure processing (HPP) is an alternative pasteurisation method that utilises high pressure to kill pathogens without degrading nutrition. This study examined HPP's impact on donor breast milk lipids, sugars and antioxidants. Metabolomics reveals diverse bioactive compounds, including lipids, polyphenols and polyketides, elucidating breast milk's complexity. Some lipid subclasses respond to HPP; ceramides decreased under both treatments, while fatty aldehydes and esters increased under specific HPP conditions. Additionally, we quantified oxidised lipids, notably dietary oxysterols (DOxS), known for pro‐oxidant and pro‐inflammatory properties. These findings enhance understanding of HPP targeted approaches and breast milk's complexity, contributing to innovative milk preservation techniques that could advance specialised infant nutrition and assist donor milk banking systems.

The Glass Ceiling in Global Health: Perspectives of Female and Male Anesthesiologists.

Gender equity is essential for improving health outcomes globally. Despite comprising 75% of the global health workforce and dominating academic global health programs, women remain underrepresented in leadership positions in global health organizations. Our study aimed to identify potential gender differences in the beliefs and attitudes regarding barriers that women anesthesiologists encounter in pursuing careers and leadership roles in global health and to identify recommendations for improving gender equity in global health. We conducted a cross-sectional online survey focusing on career leadership opportunities and challenges uniquely faced by women clinicians in global health. We obtained permission from the World Federation of Societies of Anaesthesiologists to distribute our questionnaire to their leadership committee members during 2 months (May-July 2022). The questionnaire was distributed to 164 study participants with 67 individuals (44.8% female) based in 38 different countries completing the survey (response rate 40.9%). Overall, 47.8% of the participants aspired to a leadership position in global health and 58.2% agreed women face unique barriers to global health leadership (70.0% of women compared to 48.6% of men; P = .081). Female gender (odds ratio [OR], 19.22, P = .004) and divorced marital status (OR, 746.26, P = .004) were positively associated and African ethnicity (OR, 0.002, P = .017) was negatively associated with the perception of gender bias in their career growth. The main challenges included balancing work and family responsibilities, lack of female mentors or role models, gender-based discrimination, and limited opportunities for career advancement. Men acknowledged these challenges but reported personally experiencing them to a lesser extent, particularly concerning lack of opportunities (P = .005), inadequate pay (P = .000), and lack of training (P = .000). Gender disparities exist in the pursuit of global health careers. This study underscored that more women than men perceive barriers in pursuing leadership roles in global health and that men generally encounter these obstacles to a lesser extent. Female representation in leadership positions could be supported through evidence-informed policies that promote work-life balance, improve mentorship, offer equal opportunities for career advancement and adequate pay, and combat gender-based discrimination.

Assessing the integration of refugee health data into national health information systems in Jordan, Lebanon, and Uganda

BackgroundWith the increasing number of protracted refugee crises globally, it is essential to ensure strong national health information systems (HIS) in displacement settings that include refugee-sensitive data and disaggregation by refugee status. This multi-country study aims to assess the degree of integration of refugee health data into national HIS in Jordan, Lebanon, and Uganda and identify the strengths and weaknesses of their national HIS in terms of collecting and reporting on refugee-related health indicators.MethodsThe study employs a comparative country analysis approach using a three-phase framework. The first phase involved reviewing 4120 indicators compiled from global health organizations, followed by a multi-stage refinement process, resulting in 45 indicators distributed across five themes. The second phase consisted of selecting relevant criteria from the literature, including data sources, annual reporting, disaggregation by refugee status, refugee population adjustments, accuracy, and consistency. The third phase involved assessing data availability and quality of the selected indicators against these criteria.ResultsOur analysis uncovered significant challenges in assessing the health status of refugees in Jordan, Lebanon, and Uganda, primarily stemming from limitations in the available health data and indicators. Specifically, we identified significant issues including incomplete local data collection with reliance on international data sources, fragmented data collection from various entities leading to discrepancies, and a lack of distinction between refugees and host populations in most indicators. These limitations hinder accurate comparisons and analyses. In light of these findings, a set of actionable recommendations was proposed to guide policymakers in the three countries to improve the integration of refugee health data into their national HIS ultimately enhancing refugees’ well-being and access to healthcare services.ConclusionThe current status of refugee-related health data in Jordan, Lebanon, and Uganda indicates the need for improved data collection and reporting practices, disaggregation by refugee status and better integration of refugee health data into national HIS to capture the health status and needs of refugees in host countries. Key improvement strategies include establishing a centralized authority for consistent and efficient data management, fostering transparent and inclusive data governance, and strengthening workforce capacity to manage refugee health data effectively.
