Inter-regional patient mobility in decentralised Spain: Explaining regional budget imbalances.

Inter-regional patient mobility represents both a resource and a challenge for the organization and financing of health systems, particularly in decentralised countries. We use cross-sectional time series regression analysis to test the determinants of imbalances in regional funds to finance inter-regional patient mobility for the 17 Spanish regions for the period 2014-2020. The findings indicate that highly specialised health centres and bilateral agreements partly explain the budget imbalance from inter-regional patient referrals, while local tourism partly explains the budget imbalance from non-referred patient mobility.

Patient mobility within national borders. Drivers and politics of cross-border healthcare agreements in the Spanish decentralized system.

Cross-border patient mobility has become a topic of increasing interest for policy-makers and academic scholars. However, the focus on international dynamics hinders the fact that healthcare mobility takes place within national boundaries as well, particularly in countries characterized by decentralized health systems. This paper shifts the focus from the drivers of international patient mobility to the ones of policy-making on patient mobility within national borders, analyzing more than fifty policy arrangements adopted between Spanish Regions in the period 2000-2020.

Tim/Timeless, a member of the replication fork protection complex, operates with the Warsaw breakage syndrome DNA helicase DDX11 in the same fork recovery pathway.

We present evidence that Tim establishes a physical and functional interaction with DDX11, a super-family 2 iron-sulfur cluster DNA helicase genetically linked to the chromosomal instability disorder Warsaw breakage syndrome. Tim stimulates DDX11 unwinding activity on forked DNA substrates up to 10-fold and on bimolecular anti-parallel G-quadruplex DNA structures and three-stranded D-loop approximately 4-5-fold. Electrophoretic mobility shift assays revealed that Tim enhances DDX11 binding to DNA, suggesting that the observed stimulation derives from an improved ability of DDX11 to interact with the nucleic acid substrate.

The physical interaction of Mcm10 with Cdc45 modulates their DNA-binding properties.

The eukaryotic DNA replication protein Mcm10 (mini-chromosome maintenance 10) associates with chromatin in early S-phase and is required for assembly and function of the replication fork protein machinery. Another essential component of the eukaryotic replication fork is Cdc45 (cell division cycle 45), which is required for both initiation and elongation of DNA replication. In the present study we characterize, for the first time, the physical and functional interactions of human Mcm10 and Cdc45.

The human Tim-Tipin complex interacts directly with DNA polymerase epsilon and stimulates its synthetic activity.

The Tim-Tipin complex plays an important role in the S phase checkpoint and replication fork stability in metazoans, but the molecular mechanism underlying its biological function is poorly understood. Here, we present evidence that the recombinant human Tim-Tipin complex (and Tim alone) markedly enhances the synthetic activity of DNA polymerase ε. In contrast, no significant effect on the synthetic ability of human DNA polymerase α and δ by Tim-Tipin was observed.
