Objective: To investigate the impact of establishing regional collaborative network on reperfusion time and prognosis of patients with ST-segment elevated myocardial infarction (STEMI) admitting to community hospitals without percutaneous coronary intervention (PCI) capacity (Non-PCI hospital).
Methods: A regional collaborative network was developed, consisting of a PCI center and over 30 Non-PCI hospitals and connected by a tele-transmitted real-time 12-lead electrocardiogram system. This system enables the cardiologists on duty in PCI center to help the physicians in the Non-PCI hospitals (network hospital) to confirm the diagnosis and choose a reperfusion strategy for STEMI patients. All cardiologists in PCI center and physicians in Non-PCI hospitals were trained to follow the flowchart of reperfusion strategies for STEMI patients to shorten the reperfusion time. The mean time from door of Non-PCI hospital to needle of thrombolysis (D-to-N), the mean time from door of PCI center to balloon (D-to-B) and the mean time from the first medical contact to balloon (FMC-to-B) and the 1-year mortality were compared between the 20 months before and the 20 months after establishment of the regional collaborative network for patients with the first medical contact in three network hospitals.
Results: After establishment of the regional collaborative network, the mean D-to-N time was significantly shortened from (71 ± 62) min to (28 ± 9) min (P < 0.05), the rate of D-to-N below 30 min was increased from 11% (2/18) to 74% (26/35); the mean FMC-to-B and the mean D-to-B time were remarkably reduced in both complementary percutaneous coronary intervention and transfer percutaneous coronary intervention patients (all P < 0.05), the 1-year mortality post reperfusion was reduced from 15.1% (8/53) to 7.0% (10/142) (P < 0.05).
Conclusion: The establishment of regional collaborative network could shorten the perfusion time and reduce the 1-year mortality for STEMI patients presenting to Non-PCI hospitals.

Using the e^{+}e^{-} collision data collected with the BESIII detector operating at the BEPCII collider, at center-of-mass energies from the threshold to 4.95 GeV, we present precise measurements of the cross section for the process e^{+}e^{-}→D_{s}^{+}D_{s}^{-} using a single-tag method. The resulting cross section line shape exhibits several new structures, thereby offering an input for a future coupled-channel analysis and model tests, which are critical to understand vector charmonium-like states with masses between 4 and 5 GeV.

2-dodecyl-6-methoxycyclohexa-2,5-diene-1,4-dione (DMDD) is a cyclohexanedione compound extracted from the roots of Averrhoa carambola L. Several studies have documented its beneficial effects on diabetes, Alzheimer's disease, and cancer. However, its potential neuroprotective effects on Parkinson's disease (PD) have not yet been explored.

The Swedish quality register AmbuReg collects all the country's ambulance missions. There is an increasing demand on the Emergency Medical Services (EMS) due to decreasing hospital resources and referral to self-care, primary care and mobile teams. This, in combination with fast tracks for patients with myocardial infarction, stroke, hip fracture or sepsis, increases the requirement for optimal triage at the scene.

Hydrogel-based sensors typically demonstrate conspicuous swelling behavior in aqueous environments, which can severely compromise the mechanical integrity and distort sensing signals, thereby considerably constraining their widespread applicability. Drawing inspiration from the multilevel heterogeneous structures in biological tissues, an antiswelling hydrogel sensor endowed with high strength, rapid self-recovery, and low swelling ratio was fabricated through a water-induced phase separation and coordination cross-linking strategy. A dense heterogeneous architecture was developed by the integration of "rigid" quadridentate carboxyl-Zr coordination bonds and "soft" hydrophobic unit-rich regions featuring π-π stacking and cation-π interactions into the hydrogels.
