We apply a primary healthcare (PHC) perspective to gauge Pakistan's health systems response to COVID-19, to identify stewardship lessons for integrating the PHC pandemic response. Analysis of Pakistan's response against the Astana PHC framework shows that the imperative for national survival helped mobilise an agile response across a fragmented health security context. The findings show effective multisector governance in responding to the health and social aspects of the pandemic, as well as the rapid roll-out of several public health functions and emergency care.

Background: Recent studies suggest that the use of adjunctive intraarterial alteplase after mechanical thrombectomy (MT) may improve outcomes; however, there are limited data on the use of intraarterial tenecteplase, a newer-generation lytic, in this acute ischemic stroke patient population. Here, we evaluate the use of intraarterial tenecteplase in the ALLY pilot study (Adjunctive Intraarterial Tenecteplase Following Mechanical Thrombectomy).

Methods: ALLY was a prospective, single-center, nonrandomized pilot study assessing the feasibility and safety of intraarterial tenecteplase up to 4.

The systemic administration of opioid agonists makes it both very difficult to decipher their underlying circuit mechanisms of action and to limit drug action to specific receptor subpopulations to isolate therapeutic effects from adverse side effects.
