Self-setting calcium phosphate cement for dental or surgical applications can be prepared by the addition of a liquid to a mixture of acidic and basic calcium phosphate. After hardening, the final compound becomes hydroxyapatite. Using an orthogonal central composite plan, the main factors which control the setting and the final hardness of the cement were defined and models are proposed. The mechanisms of crystallization, the role of free and linked water, and the nature of the final and intermediate compounds are described.
Purpose
The purpose of this paper is to summarize activities being undertaken by the World Health Organization (WHO) Regional Office for Europe to prevent and control COVID-19 in and beyond prisons, activities specifically designed to increase information sharing and to support Member States, to comment on potential impacts of these initiatives at country-level responses and to underline the need for a rights-based approach to managing the pandemic, including the right to vaccination.
Design/methodology/approach
The Health in Prisons Programme (HIPP) of the WHO Regional Office for Europe worked with partner organizations to review regularly the evidence on best practices in prison health and use it to inform policy recommendations at the global level. HIPP issued overarching guidance and specific tools to support implementation of measures to prevent and control the spread of COVID-19 in prisons and other custodial settings. Moreover, to monitor the emergence of outbreaks, the HIPP developed a minimum data set for countries voluntarily to report COVID-19 cases and identify situations in need of direct support.
Findings
Since May 2020, the WHO has periodically received data from Member States, leading to the development of country-specific bulletins to support countries and, whenever appropriate, to organize virtual missions to further support ministries and public health bodies responsible for managing COVID-19 in prisons.
Originality/value
The development of a specific set of indicators for prisons enables exploring data in a disaggregated manner. Monitoring response measures developed in prison enables judging their appropriateness to minimize the spread of SARS-CoV2 in prisons and alignment with guidance issued by the WHO.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
