Excess dietary sugar and its impact on periodontal inflammation: a narrative review.

Sugar is omnipresent in the current food environment and sugar consumption has drastically risen over the past century. Extensive evidence highlights the negative health consequences of consuming excess dietary sugars, leading the World Health Organization (WHO) and the American Heart Association (AHA) to devise guidelines to restrict sugar intake. According to the WHO's Global Oral Health Status Report of 2022, oral diseases and severe periodontitis are a massive public health problem, and dietary sugars are a modifiable risk factor. We conducted a literature review using key databases to summarise the health effects of excessive sugar consumption and their potential role in periodontal inflammation. Available evidence suggests that excess dietary fructose and sucrose can cause low-grade systemic inflammation; and induce dysbiosis in both gut and the oral microbiota. Also, dietary sugar is potentially addictive and hypercaloric and its overconsumption can lead to obesity, metabolic syndrome, and other risk factors for periodontal inflammation. Hence, an unbalanced diet with excess dietary sugars holds the potential to initiate and aggravate periodontal inflammation. In the modern food environment that enables and facilitates a high-sugar diet, adopting a diverse diet and restricting sugar intake according to WHO and AHA guidelines seem beneficial to systemic and periodontal health. Since clinical evidence is limited, future research should study the effectiveness of dietary interventions that control sugar consumption in preventing and managing the global public health problem of periodontal inflammation.

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.

Health facility assessment of small and sick newborn care in low- and middle-income countries: systematic tool development and operationalisation with NEST360 and UNICEF

BackgroundEach year an estimated 2.3 million newborns die in the first 28 days of life. Most of these deaths are preventable, and high-quality neonatal care is fundamental for surviving and thriving. Service readiness is used to assess the capacity of hospitals to provide care, but current health facility assessment (HFA) tools do not fully evaluate inpatient small and sick newborn care (SSNC).MethodsHealth systems ingredients for SSNC were identified from international guidelines, notably World Health Organization (WHO), and other standards for SSNC. Existing global and national service readiness tools were identified and mapped against this ingredients list. A novel HFA tool was co-designed according to a priori considerations determined by policymakers from four African governments, including that the HFA be completed in one day and assess readiness across the health system. The tool was reviewed by > 150 global experts, and refined and operationalised in 64 hospitals in Kenya, Malawi, Nigeria, and Tanzania between September 2019 and March 2021.ResultsEight hundred and sixty-six key health systems ingredients for service readiness for inpatient SSNC were identified and mapped against four global and eight national tools measuring SSNC service readiness. Tools revealed major content gaps particularly for devices and consumables, care guidelines, and facility infrastructure, with a mean of 13.2% (n = 866, range 2.2–34.4%) of ingredients included. Two tools covered 32.7% and 34.4% (n = 866) of ingredients and were used as inputs for the new HFA tool, which included ten modules organised by adapted WHO health system building blocks, including: infrastructure, pharmacy and laboratory, medical devices and supplies, biomedical technician workshop, human resources, information systems, leadership and governance, family-centred care, and infection prevention and control. This HFA tool can be conducted at a hospital by seven assessors in one day and has been used in 64 hospitals in Kenya, Malawi, Nigeria, and Tanzania.ConclusionThis HFA tool is available open-access to adapt for use to comprehensively measure service readiness for level-2 SSNC, including respiratory support. The resulting facility-level data enable comparable tracking for Every Newborn Action Plan coverage target four within and between countries, identifying facility and national-level health systems gaps for action.

Assessing the effect of cardiovascular disease on work productivity and financial loss among school teachers in Peninsular Malaysia: a nested case-control study.

School teachers may have an increased risk of cardiovascular disease (CVD), potentially affecting their work productivity. However, limited data exists on the impact of CVD on teachers' productivity in Malaysia. Our objectives were to assess work productivity loss (absenteeism and presenteeism) as well as to determine the associated annual monetary loss among school teachers who experienced incident CVD in Peninsular Malaysia. We adopted a nested case-control design within a cohort of school teachers. Working teachers from six states of Peninsular Malaysia, and had experienced incident CVD before a right-censored date (31st December 2021) were defined as cases. Incident CVD was operationally defined as the development of non-fatal acute coronary syndrome (ACS), stroke, congestive cardiac failure, deep vein thrombosis or peripheral arterial disease before the censored date. Controls were working teachers who did not acquire an incident CVD before the similar right-censored date. All controls were randomly selected, with a ratio of one case to four controls, from among the working teachers in one of the states in Peninsular Malaysia. We used a shortened version of the Malay-validated World Health Organization-Health and Work Performance Questionnaire (WHO-HPQ) to estimate the workplace productivity effect among teachers with incident CVD (cases). The same questionnaire was distributed to teachers in a single state of Peninsular Malaysia who did not experience incident CVD (controls). Absenteeism, presenteeism and annual monetary loss were computed based on the scoring rules in the WHO-HPQ. Analysis of covariance was performed with covariate adjustment using propensity scores. The bootstrapping method was applied to obtain better estimates of marginal mean differences, along with standard errors (SE) and appropriate effect sizes. We recruited 48 cases (baseline mean age = 42.4 years old, 54.2% females) and 192 randomly selected controls (baseline mean age = 36.2 years old, 99.0% females). The majority of the cases had ACS (73.9%). No significant difference was observed in absenteeism between cases and controls. The mean self-rated job performance score was lower for cases (7.63, SE = 0.21) compared to controls (8.60, SE = 0.10). Marginal mean scores of absolute presenteeism among cases (76.30) were lower (p<0.05, eta squared = 0.075) than controls (85.97). The marginal mean annual cost of presenteeism was higher in cases (MYR 21,237.52) compared to controls (MYR 12,089.74) (p<0.05, eta squared = 0.082). Absolute presenteeism was lower among school teachers who experienced incident CVD and the annual cost of presenteeism was substantial. Implementing supportive work strategies in school settings is recommended to increase absolute presenteeism, which can lead to a reduction in the annual cost of presenteeism among teachers experiencing incident CVD.

Rethinking the World Health Organization's leadership of global health governance and the global health surveillance systems.

Global health governance is a strategic priority for the World Health Organization (WHO), and the public health surveillance system (PHSS) is a fundamental element of the global health governance structure to timely identify emerging diseases and guide global public health decisions and actions. This analysis explores the overall landscape of global health governance, with a specific focus on the PHSS to understand whether the existing governance landscape facilitates or undermines the WHO's ability to formulate and implement global health policies and initiatives. To achieve this, the existing evidence was reviewed, and synthesized with the experts' perspectives. It is reported that fragmentation is the main drawback of the global health governance landscape, necessitating reorganization and restructuring. The disintegration of PHSS at the global, regional and local levels is associated with a lack of leadership, misalignment with global health priorities, imbalance in coverage of surveillance systems, inadequate innovative technology and digitalization, and fragmented data and information systems. The fragmentation and disintegration of global health governance undermine the effectiveness of the WHO's global health strategic directions and programmes and hinder its ability to govern and guide the global, regional and national public health emergency response. Strategic rethinking of the WHO's governance is essential because strong governance and leadership lead to a robust, aligned and effective PHSS.

Scaling up Surgical Capacity in Kenya: The Kenya Hospital Assessment Tool (K-HAT)

IntroductionAlthough substantial progress has been achieved to bring surgical care to the forefront of global health discussions, a number of low-and middle-income countries are still in the process of developing a National Surgical, Obstetric, and Anesthesia Plan (NSOAP). This paper describes the initial step toward the development of the NSOAP through the creation of the Kenya National Hospital Assessment Tool (K-HAT). MethodsA study protocol was developed by a multisectoral collaborative group that represented the pillars of surgical capacity development in Kenya. The K-HAT was adapted from two World Health Organization (WHO) tools: the Service Availability and Readiness Assessment tool and the Situational Analysis Tool. The survey tool was deployed on Open Data Kit, an open-source electronic encrypted database. This new locally adapted tool was pilot tested in three hospitals in Kenya and subsequently deployed in Level 4 facilities. ResultsEighty-nine questions representing over 800 data points divided into six WHO Health Systems Strengthening sections comprised the K-HAT which was deployed to over 95% of Level 4 hospitals in Kenya. When compared to the WHO Service Availability and Readiness Assessment tool, the K-HAT collected more detailed information. The pilot test team reported that K-HAT was easy to administer, easily understood by the respondents, and that it took approximately 1 hour to collect data from each facility. ConclusionsThe K-HAT collected comprehensive information that can be used to develop Kenya's NSOAP.

Realigning noncommunicable disease monitoring with health systems priorities in the Africa region.

The African region of the World Health Organization (WHO) recently adopted a strategy aimed at more comprehensive care for noncommunicable diseases (NCDs) in the region. The WHO's World Health Assembly has also newly approved several ambitious disease-specific targets that raise the expectations of chronic care and plans to revise and update the NCD-Global Action Plan. These actions provide a critically needed opportunity for reflection and course correction in the global health response to NCDs. In this paper, we highlight the status of the indicators that are currently used to monitor progress towards global goals for chronic care. We argue that weak health systems and lack of access to basic NCD medicines and technologies have prevented many countries from achieving the level of progress required by the NCD epidemic, and current targets do little to address this reality. We identify gaps in existing metrics and explore opportunities to realign the targets with the pressing priorities facing today's health systems.

Overcoming the challenges facing Nepal’s health system during federalisation: an analysis of health system building blocks

IntroductionNepal’s move to a federal system was a major constitutional and political change, with significant devolution of power and resources from the central government to seven newly created provinces and 753 local governments. Nepal’s health system is in the process of adapting to federalism, which is a challenging, yet potentially rewarding, task. This research is a part of broader study that aims to explore the opportunities and challenges facing Nepal’s health system as it adapts to federalisation.MethodsThis exploratory qualitative study was conducted across the three tiers of government (federal, provincial, and local) in Nepal. We employed two methods: key informant interviews and participatory policy analysis workshops, to offer an in-depth understanding of stakeholders’ practical learnings, experiences, and opinions. Participants included policymakers, health service providers, local elected members, and other local stakeholders. All interviews were audio-recorded, transcribed, translated into English, and analysed thematically using the six WHO (World Health Organization) health system building blocks as a theoretical framework.ResultsParticipants noted both opportunities and challenges around each building block. Identified opportunities were: (a) tailored local health policies and plans, (b) improved health governance at the municipality level, (c) improved health infrastructure and service capacity, (d) improved outreach services, (e) increased resources (health budgets, staffing, and supplies), and (f) improved real-time data reporting from health facilities. At the same time, several challenges were identified including: (a) poor coordination between the tiers of government, (b) delayed release of funds, (c) maldistribution of staff, (d) problems over procurement, and (e) limited monitoring and supervision of the quality of service delivery and data reporting.ConclusionOur findings suggest that since federalisation, Nepal’s health system performance is improving, although much remains to be accomplished. For Nepal to succeed in its federalisation process, understanding the challenges and opportunities is vital to improving each level of the health system in terms of (a) leadership andgovernance, (b) service delivery, (c) health financing, (d) health workforce, (e) access to essential medicines and technologies and (f) health information system.

Systematizing Information Use to Address Determinants of Health Worker Health in South Africa: A Cross-sectional Mixed Method Study

BackgroundRecognizing that access to safe and healthy working conditions is a human right, the World Health Organization (WHO) calls for specific occupational safety and health (OSH) programs for health workers (HWs). The WHO health systems’ building blocks, and the International Labour Organization (ILO), highlight the importance of information as part of effective systems. This study examined how OSH stakeholders access, use, and value an occupational health information system (OHIS). MethodsA cross-sectional survey of OSH stakeholders was conducted as part of a larger quasi experimental study in four teaching hospitals. The study hospitals and participants were purposefully selected and data collected using a modified questionnaire with both closed and open-ended questions. Quantitative analysis was conducted and themes identified for qualitative analysis. Ethics approval was provided by the University of Pretoria and University of British Columbia. ResultsThere were 71 participants comprised of hospital managers, health and safety representatives, trade unions representatives and OSH professionals. At least 42% reported poor accessibility and poor timeliness of OHIS for decision-making. Only 50% had access to computers and 27% reported poor computer skills. When existing, OHIS was poorly organized and needed upgrades, with 85% reporting the need for significant reforms. Only 45% reported use of OHIS for decision-making in their OSH role. ConclusionGiven the gap in access and utilization of information needed to protect worker’s rights to a safe and healthy workplace, more attention is warranted to OHIS development and use as well as education and training in South Africa and beyond.

Gaps in monitoring global progress toward universal health coverage among disadvantaged populations: the case of people living in prison

Abstract The United Nations’ Sustainable Development Goals (SDGs) represent a sweeping initiative to create a sustainable and equitable global future. SDG 3 focuses on the health and wellbeing of the world. Expanding universal health coverage is a central component of SDG 3 and has been a focus area of the World Health Organization (WHO), which aims to expand universal health coverage to an additional 1 billion people by this year (2023). The WHO developed an index (indicator 3.8.1) intended to monitor coverage of essential health services across the globe. However, this indicator fails to incorporate health coverage for people in prisons. People incarcerated in prisons across the globe have high rates of physical health, mental health, and substance use conditions compared with the general population, and they are frequently excluded from policies and services available in the general population. For example, in some countries, like Australia and the United States, people in prison are legislatively excluded from the public health insurance programs available to the general population. Exclusion of prison health coverage from the WHO's universal health coverage indicator likely results in overestimation of health coverage in most countries and fails to identify gaps in care during and after periods of incarceration. We believe prison health coverage should be incorporated into the WHO's 3.8.1 indicator, which would more accurately capture a country's health coverage among its most disadvantaged populations. Monitoring of prison health coverage will require improved measurement of quality and service availability in prisons, which is sorely lacking in most countries.

A GIS-based approach to identifying communities underserved by primary health care services-An Afghanistan case study.

Afghanistan has been in an active state of conflict and war for twenty continuous years. Social services like health and education have been badly affected, facing issues such as service disruption, brain drain, and generalized instability. Health indices that provide proxy indicators for general population wellness, such as maternal health, child mortality, and immunization coverage, show that the health services available to the Afghan population are sub-optimal. Investment in social service and interventions has increased. The World Bank and the United Nations through its agencies (The World Health Organization (WHO) and United Nations' Children's Fund (UNICEF) are providing social support through targeted and strategic programs. However, the topographic and environmental realities of Afghanistan, with its broad mountain coverage, propensity toward natural disasters, and latent conflict, has made data and information gathering arduous. Since data is essential for measurement and management, the WHO Health Emergencies (WHE) information management unit at WHO Afghanistan has delivered an innovative form of data analysis, specialized and targeted at providing improved information on communities that are not adequately covered by health services. Deploying a geographical information system (GIS) approach, the WHE team has collated primary and secondary data from a combination of datasets to produce a far-reaching piece of analysis. The analysis of underserved communities in hard to reach, remote locations, provides a live, evidence-based information product. This provides a working tool that is essential to primary health programming and intervention in Afghanistan. The estimates show that approximately 9.5 million individuals in 22,181 villages across 34 provinces are underserved by primary health services. This paper is presented to explain the underpinning methodology.

Status of Health-care Systems for Diabetes Mellitus and Diabetic Retinopathy in Jordan: Stakeholders and Health-care Providers Survey.

The purpose of the study was to evaluate the status of health services for diabetes mellitus (DM) and diabetic retinopathy (DR) in Jordan in terms of availability and accessibility by interviewing people engaged with health-care process including decision makers, professional providers, and community representatives. This is a qualitative study where participants were invited to respond by direct interview to a standard questionnaire that is validated by the World Health Organization (WHO), "Tool for Assessment of Diabetic Retinopathy and DM Management Systems". The questionnaire casts out of the WHO Health Systems Framework concept, assessing the presence of programs, guidelines, health technology and workforce, health promotion, and financing of DM and DR care in Jordan. Forty-two participants were included. DM is considered as priority in Jordan, but no programs are implemented. National guidelines are present for DM but not for DR. Networking should be improved between different disciplines caring for DM and DR. Human resources for DM and DR care were found insufficient and inadequately distributed. Health technology is only present in major cities and central hospitals. There is no nationwide data on disease burden nor a screening program for DR. More collaborated efforts should be spent on health education and raising awareness among people living with diabetes about the risk of DR. Advanced DM and DR care is not accessible to most people. Programmatic efforts from the government and NGOs must formulate a national action plan to reduce the human and financial impact of the disease in Jordan.

Assessment of a Tertiary Hospital’s Systems Thinking Approach Using the World Health Organization Health System Framework in Response to the COVID-19 Pandemic in Nigeria

Background: The coronavirus disease 2019, (COVID-19) pandemic dealt a catastrophic blow to health systems globally, especially those of middle and low-income-countries, whose health systems were already frail, pre-pandemic. The World Health Organization (WHO) recognizes six building blocks (BBs) for a sturdy health system, whose synergistic interaction, through a systems thinking approach, guarantees optimal and equitable health outcomes for the populace, while shielding them from financial risk. &#x0D; Objectives: To showcase a Nigerian tertiary hospital’s response to the COVID-19 pandemic, through the application of systems thinking, to the WHO health systems BBs.&#x0D; Methods: A questionnaire-based survey (utilizing a Likert scale of 1=very poor; 2=poor; 3=fair; 4=good and 5=excellent) of the hospital-wide efforts, employed by the leadership of the University of Nigeria Teaching Hospital (UNTH) Enugu, utilizing the WHO BBs, during the COVID-19 pandemic, assessed the perceived impact of the individual BBs on the hospital system. Eighty key stakeholders (Females=55%), heads of departments and supervisors, comprising various categories of medical personnel, overseeing twenty critical service areas of the hospital undertook the survey.&#x0D; Results: Leadership/Governance ranked highest in impact among the BBs (68.6%), with the availability of Medical products/Technology (65.9%), and Service delivery (64.4%) trailing closely at second and third, respectively. Perceived robustness and overall motivation of the Health Workforce was least ranked at 57.1%, closely followed by Healthcare Financing (58.2%) and Health Information Systems (61.9%).&#x0D; Conclusion: At an average cumulative score of 62.7% for all the BBs, the UNTH leadership may be adjudged to have performed creditably in their efforts at COVID-19 containment. Staff welfare should be enhanced, to ensure a well-motivated staff which will likely translate to improved service delivery.

Promoting Useful and Usable Scientific Evidence in Health Emergencies and Disaster Risk Management: The WHO Health EDRM Knowledge Hub

Introduction:In order to promote useful and usable scientific evidence for health emergency and disaster risk management (Health EDRM), the World Health Organization (WHO) Health EDRM Knowledge Hub has been established as part of the WHO Thematic Platform for Health EDRM research network (Health EDRM RN). The Knowledge Hub aims to extend scientific knowledge; strengthen evidence-based practice in the management of health risks in emergencies and disasters; create and develop a competent network in the Health EDRM community; and integrate research, policy and practice.Method:To begin with, the Knowledge Hub has five interconnected research themes: (1) health data management; (2) psychosocial support; (3) health needs of sub-populations; (4) health workforce development; and (5) research methods. Systematic literature reviews and expert consultations have assessed current research under each theme and identified potential knowledge gaps. The work of the Knowledge Hub is advised by members of the Health EDRM RN and staff in WHO regional offices.Results:The WHO Health EDRM Knowledge Hub will be a platform for providing and exchanging up-to-date evidence. This will include information on validated methods for managing health data and identifying health needs in specific subpopulations. The Knowledge Hub will raise awareness of psychosocial support, health workforce development and research before, during and after disasters. It is targeted to policy-makers, researchers, practitioners and the broader community with the aim of accelerating evidence-informed policy and programs. This will support implementation of the Sendai Framework for Disaster Risk Reduction 2015–2030, the WHO Health EDRM Framework, and other related global, regional and national agendas.Conclusion:This paper introduces this new initiative and describes its objectives, design, and implementation. Additionally, it provides an overview of the Knowledge Hub and invites session participants to provide insights into their current needs and to make recommendations for improvement.

Disaster Preparedness at the Primary Health Care Level: The Proposal of a New Framework

Introduction:With the publication of the Health Emergency and Disaster Risk Management (H-EDRM) Framework in 2019, the World Health Organization (WHO) emphasized the need for disaster preparedness in all sectors of the health system, including primary health care (PHC). PHC disaster preparedness plays a crucial role in guaranteeing continuity of care and responding to the health needs of vulnerable populations during disasters. While this is universally acknowledged as an important component of disaster management (DM), there is still a severe paucity of scholarship addressing how to practically ensure that a PHC system is prepared for disasters. The objective of this study is to propose a new framework that describes key characteristics for PHC disaster preparedness and lays the groundwork to deliver operational recommendations to assess and improve PHC disaster preparedness.Method:A systematic literature review including the following online scientific databases was performed: Cochrane Library, Embase, Medline, National Library of Medicine, PubMed, Scopus, and Web of Science. Gray literature was also found by searching in: Trove, Mednar, and OpenGray. A total of 145 records were analyzed.Results:Twenty-five characteristics that contribute to a well-prepared PHC system were identified and categorized according to the WHO Health System Building Blocks to form a new PHC disaster preparedness framework.Conclusion:The findings will contribute to the elaboration of a set of guidelines for PHC systems to follow in order to assess and boost their disaster preparedness. This will hopefully help to raise awareness among international policymakers and health practitioners on the importance to design interventions that integrate PHC into overall DM strategies, as well as to assess the preparedness of PHC systems in different political, developmental, and cultural contexts. The proposed framework is currently being used by our research group as groundwork for the creation of an assessment tool for evaluating all-hazards preparedness at the PHC level.

Monkeypox: A review of a zoonotic disease of global public health concern.

Background: The rising circulation of the monkeypox virus while the COVID-19 is still ongoing in non-endemic countries is a significant global health threat. In this article, we have discussed the epidemiology, aetiology, and pathogenesis of the monkeypox virus to provide our current knowledge of the disease. Also, we discussed the ongoing efforts of the international health organizations to curtail the present epidemic and we finally provide recommendations for early detection and response. Methods: We did a rapid literature search on PubMed, EMBASE, World Health Organization (WHO), the Centers for Disease Control and Prevention (CDC), and other trusted databases for recent articles (1958-2022) published in English-focusing on the outbreaks of monkeypox disease, epidemiology, pathogenesis, aetiology, prevention, and control in endemic and non-endemic countries. Keywords such as "Monkeypox", "Monkeypox virus", "Poxviridae", "Orthopoxvirus", "Smallpox", and "Smallpox Vaccine" were considered in our search based on MESH medical subject headings. Results: Our review highlights four important findings. First, a cumulative of 1285 monkeypox cases have been documented and reported by the WHO in non-endemic countries as of June 8, 2022. Second, international travel contributes to the increase in cases in non-endemic countries. Third, the origin of the outbreak, the pattern of transmission, and the risk of infections is not fully understood. Fourth, there is an ongoing effort by the WHO, CDC, and other international health organization to control the spread of the monkeypox disease. Conclusion: Our findings underline the need to reassess research priorities on the origin, transmission pattern, and risk factors for infection of monkeypox. Also, we provide recommendations under the One Health spectrum to prevent further spread of the disease.

Health-Promoting Schools Project for Palestine Children's Oral Health

ObjectivesThe aim of this work was to assess the oral health outcome of a 2-year comprehensive school oral health programme based on school-health education combined with supervised toothbrushing using 1450-ppm fluoride toothpaste amongst schoolchildren in Palestine. MethodsA quasi-experimental study (2016–2018) recruited 3939 schoolchildren aged 5 to 6 years from 30 intervention schools (n = 2333) and 31 comparison schools (n = 1606). At baseline and postintervention, mothers and schoolteachers completed World Health Organization (WHO) self-administered questionnaires about oral health of children, oral health behaviour, and family factors. Of the initial participants 75.8 per cent took part in the follow up studies. In addition, 25 calibrated dentists examined dental caries of children according to WHO criteria. Trained teachers provided comprehensive oral health education to children in the classrooms and held regular oral health sessions for mothers. Children brushed their teeth with fluoride-containing toothpaste (1450 ppm fluoride). Student t-test and logistic regression were used in the statistical analysis of changes in dental health and related knowledge, behaviours, and attitudes (P < .05). ResultsIn both dentitions, dental caries experience declined over the project. The reduction in Decayed, Missing and Filled permanent Teeth and Decayed, Missing and Filled Surfaces in permanent teeth was 23.3% and 23.2% (P < .001), respectively. The drop in caries experience indices in the Gaza Strip was 8 to 4 times higher than in West Bank, and it reached 47.4% reduction. Mothers and teachers showed improvement in positive knowledge and attitudes towards dental care. Involvement of schoolteachers in oral health in schools and acceptance of dental health education materials significantly enhanced oral health behaviour of children. ConclusionsThe project recommends national implementation of an intervention for the improvement of oral health of schoolchildren and their parents in conflict zones. The project shows the importance of the WHO Health Promoting Schools concept and involving classroom-based health education carried out by schoolteachers. It is suggested to explore the health care system's capacity in hosting effective oral health programme and maintain its efficacy.

COVID-19 Mortality and Progress Toward Vaccinating Older Adults - World Health Organization, Worldwide, 2020-2022.

After the emergence of SARS-CoV-2 in late 2019, transmission expanded globally, and on January 30, 2020, COVID-19 was declared a public health emergency of international concern.* Analysis of the early Wuhan, China outbreak (1), subsequently confirmed by multiple other studies (2,3), found that 80% of deaths occurred among persons aged ≥60 years. In anticipation of the time needed for the global vaccine supply to meet all needs, the World Health Organization (WHO) published the Strategic Advisory Group of Experts on Immunization (SAGE) Values Framework and a roadmap for prioritizing use of COVID-19 vaccines in late 2020 (4,5), followed by a strategy brief to outline urgent actions in October 2021.† WHO described the general principles, objectives, and priorities needed to support country planning of vaccine rollout to minimize severe disease and death. A July 2022 update to the strategy brief§ prioritized vaccination of populations at increased risk, including older adults,¶ with the goal of 100% coverage with a complete COVID-19 vaccination series** for at-risk populations. Using available public data on COVID-19 mortality (reported deaths and model estimates) for 2020 and 2021 and the most recent reported COVID-19 vaccination coverage data from WHO, investigators performed descriptive analyses to examine age-specific mortality and global vaccination rollout among older adults (as defined by each country), stratified by country World Bank income status. Data quality and COVID-19 death reporting frequency varied by data source; however, persons aged ≥60 years accounted for >80% of the overall COVID-19 mortality across all income groups, with upper- and lower-middle-income countries accounting for 80% of the overall estimated excess mortality. Effective COVID-19 vaccines were authorized for use in December 2020, with global supply scaled up sufficiently to meet country needs by late 2021 (6). COVID-19 vaccines are safe and highly effective in reducing severe COVID-19, hospitalizations, and mortality (7,8); nevertheless, country-reported median completed primary series coverage among adults aged ≥60 years only reached 76% by the end of 2022, substantially below the WHO goal, especially in middle- and low-income countries. Increased efforts are needed to increase primary series and booster dose coverage among all older adults as recommended by WHO and national health authorities.

Performance evaluation of health houses in Iraq 2021-2022: A descriptive study.

A health house (HH) is a basic health facility in rural Iraq. The function of a HH is to provide simple health services and treatments such as giving injections, dressing simple wounds, and monitoring mother and child health. The duties also include dispensing medications, measuring blood pressure, and the daily monitoring of chlorine levels in water. These HHs also provide awareness on different subjects. The main objectives of this study are to assess the availability of the basic features of the HHs and core components of the framework of the World Health Organization (WHO) building blocks. A multistage sampling technique was used to select 50 HHs out of 497 in Iraq. A questionnaire comprising closed-ended questions was developed to be completed using the researcher's observations and interviews with the healthcare workers in the HHs. The questionnaire covered the basic features of HHs as recommended by the Iraq Ministry of Health (MOH) and the six WHO health system building blocks. Fifty HHs were enrolled in the study. The availability score of basic features was 43.6% and the general service score was 55.1%. The service-specific score was 23.3%, the health workforce score was 29.6%, and the health information system score was 79.5%. The availability of essential medicines score was 21.2%, the health financing system score was 0.0%, and the leadership and governance score was 66.7%. The HHs need to follow the standard criteria determined by the Iraq MOH to ensure the proper functioning of the health outlets.
