Substance use atlas 2021

The Substance use atlas 2021 reports on progress made in the implementation of the regional framework for action to strengthen the public health response to substance use which was endorsed in 2019 at the 66th session of the Regional Committee for the Eastern Mediterranean Region. Following endorsement of the regional framework the Regional Committee mandated WHO to monitor and report biennially on its implementation. The atlas maps the resources and capacities of the countries of the Region to respond to the problems of substance use. It also highlights challenges and gaps and identifies areas where the public health response to substance use problems needs to be strengthened. The atlas provides aggregated regional information and individual country profiles with detailed information on available resources and capacities at the country level.

Atlas of African health statistics 2022: Health situation analysis of the WHO African Region

The population of the World Health Organization's (WHO) African Region was estimated to be 1 120 161 000 in 2020 and about 14.4% of the world's population of 7 758 157 000. It was 8 billion in 20211 . It is the third largest population among the WHO regions after South-East Asia and the Western Pacific. Between 2019 and 2020, the population differential was equivalent to that of a state of more than 28 million inhabitants. The five most populated countries account for more than 45% of the Region's population. Among these, Nigeria and the Democratic Republic of the Congo represent about 50% of the population of the West African and Central African subregions, respectively, and Ethiopia represents about 20% of the population of the East and Southern Africa subregions. The average annual population growth in Africa was 2.5% in 2020. If the heterogeneity of the population growth between the regions of the world and between countries in the same subregion is considered, countries from and East and Southern Africa subregions seem to have lower population growth rates than countries in other large subregions, which show significantly higher increases. The current population density of Africa is low, estimated to be 36 inhabitants per km2 for the whole continent. However, many areas are uninhabitable and some countries have relatively large populations. High population density is a concern that must be addressed through policies, because it could generate surges and high concentrations of populations in mega cities and urban slums, which can be an issue when it comes to accessing various qualitative services. Gross domestic product (GDP) reflects a country's resources and therefore its potential to provide access to services to its people, particularly health services. This dynamic creates a circle, with healthier people going to work and contributing to the production of wealth for the benefit of the country. The most vulnerable people live from agriculture in rural areas, or in conflict-affected states. Difficulties in accessing health services, low education and inequalities between men and women are additional obstacles to poverty reduction. The population of sub-Saharan Africa is expected to almost double over the next three decades, growing from 1.15 billion in 2022 to 2.09 billion in 2050. The world's population is expected to grow from 7.94 billion at present to 8.51 billion in 2030 and 9.68 billion in 2050. The demographic dividend2 for African countries will emanate from the acceleration of economic growth following a de crease in fertility with a change in the structure of the age pyramid where the active population, that is those aged 18­65 years, will be more important, reaching a certain optimum to make positive the ratio between the population able to finance health and education systems and the population that benefits from these systems. This is the human capital for development at a given moment. The demographic dividend appears to be an opportunity and an invitation to action, but it is also a real challenge, that of creating sustainable jobs to generate the development to activate the economic growth lever.

Morphometric Study of the Atlas / Estudo morfométrico do atlas

Abstract Objective To determine the anatomical parameters of the atlas (C1) in a sample of the Brazilian population and compare them with the results already presented in the literature for other populations and, thus, to identify and change the indications of implants used in the treatment of the upper cervical spine. Methods We performed a retrospective observational study of a prospective database, including 100 patients seen between January 2012 and December 2013. We used axial and sagittal sections of computed tomography (CT) scans. The parameters studied were; axial: distance from posterior tubercle to the screw entry point (DPT_EP), safety angle of the axial screw (SA_AS), ideal axial screw length (_ASL) and distance of the spinal canal from the transverse foramen (DSC_TF); Sagittal: ideal sagittal screw length (_SSL), safety angle of the sagittal screw (SA_SS) and posterior arch thickness (_PAT). All of the parameters were divided according to age, gender, and left and right sides. Results The minimum mean point of entry ranged from 20 mm to 22.7 mm. The average security zone ranged from 18.09º to 23.68º. The mean posterior arch thickness ranged from 7.21 mm to 8.95 mm. The lowest averages were found in females. Using an original and reproducible technique of CT evaluation. Conclusion The anatomical parameters of the atlas found in the sample of the studied population were similar to those previously presented in the literature. However, differences between the sexes were observed.

Resumo Objetivo Determinar os parâmetros anatômicos do atlas (C1) em uma amostra da população brasileira, compará-los aos resultados já apresentados na literatura para outras populações e, assim, identificar e alterar as indicações dos implantes utilizados no tratamento das afecções da coluna cervical alta. Métodos Foi realizado um estudo observacional retrospectivo de um banco de dados prospectivo, incluindo 100 pacientes atendidos entre janeiro de 2012 a dezembro de 2013. Foram utilizados cortes axiais e sagitais de tomografias computadorizadas (TCs). Os parâmetros estudados foram; axial: ponto de entrada do parafuso (DTPPE), ângulo de segurança (ADSPA), tamanho ideal do parafuso (TPA) e tamanho da massa lateral entre os forames vertebral e transverso (DCVFT); sagital: tamanho ideal do parafuso (TPS), ângulo de segurança (ADSPS) e espessura do arco posterior (EAP). Todos os parâmetros foram divididos de acordo com a idade, gênero e lado esquerdo e direito. Resultados A média mínima do ponto de entrada variou de 20 mm a 22,7 mm. A zona de segurança média variou de 18,09º a 23,68º. A espessura média do arco posterior variou entre 7,21 mm e 8,95 mm. As menores médias foram encontradas no sexo feminino. Por meio de uma técnica original e reprodutível de avaliação de TC. Conclusão Os parâmetros anatômicos do atlas encontrados na amostra da população estudada foram semelhantes aos apresentados previamente na literatura. No entanto, foram observadas diferenças entre os sexos.
