Addressing immediate public health needs as part of Afghan evacuees' resettlement to the United States during the COVID-19 pandemic.

OBJECTIVES: Since the removal of US troops from Afghanistan in 2021, the United States welcomed Afghan evacuees through Operation Allies Welcome. Using cell phone accessibility, the CDC Foundation worked with public-private partners to protect evacuees from the spread of COVID-19 and provide accessibility to resources. STUDY DESIGN: This was a mixed methods study. METHODS: The CDC Foundation activated its Emergency Response Fund to accelerate public health components of Operation Allies Welcome, including testing, vaccination, and COVID-19 mitigation and prevention. The CDC Foundation began the provision of cell phones to evacuees to ensure access to public health and resettlement resources. RESULTS: The provision of cell phones provided connections between individuals and access to public health resources. Cell phones provided means to supplement in-person health education sessions, capture and store medical records, maintain official resettlement documents, and assist in registration for state-administered benefits. CONCLUSIONS: Phones provided necessary connectivity to friends and family for displaced Afghan evacuees and higher accessibility to public health and resettlement resources. As many evacuees did not have access to US-based phone services upon entry, provision of cell phones and plans for a fixed amount of service time provided a helpful start in resettlement while also being a mechanism to easily share resources. Such connectivity solutions helped to minimize disparities among Afghan evacuees seeking asylum in the United States. Provision of cell phones by public health or governmental agencies can help to provide equitable resources to evacuees entering the United States for social connection, healthcare resources, and resources to assist in the process of resettlement. Further research is needed to understand the generalizability of these findings to other displaced populations.

An intra-action review conducted by the CDC Foundation during COVID-19 to evaluate emergency response procedures.

OBJECTIVES: During times of emergency response, the CDC Foundation leverages partnerships and relationships to better understand the situation and respond rapidly to save lives. As the COVID-19 pandemic began to unfold, an opportunity became clear to improve our work in emergency response through documentation of lessons learned and incorporating them into best practices. STUDY DESIGN: This was a mixed methods study. METHODS: The CDC Foundation Response, Crisis and Preparedness Unit conducted an internal evaluation via an intra-action review to evaluate and rapidly improve emergency response activities to provide effective and efficient response-related program management. RESULTS: The processes developed during the COVID-19 response to conduct timely and actionable reviews of the CDC Foundation's operations led to the identification of gaps in the work and management processes and to creation of subsequent actions to address these issues. Such solutions include surge hiring, establishing standard operating procedures for processes not yet documented, and creating tools and templates to streamline emergency response operations. CONCLUSIONS: The creation of manuals and handbooks, intra-action reviews, and impact sharing for emergency response projects led to actionable items meant to improve processes and procedures and the ability of the Response, Crisis and Preparedness Unit to quickly mobilize resources directed toward saving lives. These products are now open-source resources that can be used by other organizations to improve their own emergency response management systems.

The effects of dynamic loading on intracalcaneal wood implants and on the tissues surrounding them.

The dorsal parts of the calcanei of rabbits were resected and replaced with similarly-shaped implants made of ash wood. In each case the Achilles tendon was reinserted into the projecting part of the implant so as to subject the latter to the dynamic loads generated by use of the limb. The implants were removed from some of the animals after 5 weeks and from the others after 14 weeks. They were evaluated by preparing undecalcified microtome sections and ground sections which were examined by light microscopy and microradiography. Some of the animals underwent vital staining so as to produce polychromatic sequential labelling of the calcaneal specimens. In the area of insertion of the Achilles tendon soft tissue grew into the larger pores of the wood and, in some cases, differentiated into cartilage. Every implant remained stably anchored in the calcaneus. In every animal the intracalcaneal part of the implant became surrounded by new bone which was in direct contact with the surface of the implant and which also formed in the pores of the wood, even all rabbits loaded the operated foot. The formation of new bone in and around the implants demonstrates the basic feasibility of using ash wood as an isoelastic implant material in bone.

Alcohol-extracted and sterilised cylinders of ash- and birchwood were implanted into the tibia of rabbits. The selection criteria of these two wood species were thoroughly described. 28 implants were evaluated after 3, 5, 14 and 32 weeks using undecalcified microtome sections and ground sections employing polychromatic sequential-labelling and microradiography. In spite of a foreign-body-tissue reaction new bone is formed around the implants and within the pores of the wood as well. Both wood species therefore seem to be suitable implant materials, which were anchoraged by the bone itself. A tensile strength and elastic properties comparable to bone and simple handling would be the advantages of this material.
