RESUMEN
BACKGROUND: To provide clinicians with sufficient information for selecting optimal access strategies for patients with end-stage renal disease, the utilization of health-care services of patients receiving arteriovenous fistulas (AVFs), arteriovenous grafts (AVGs), and central venous catheters (CVCs) are crucial topics that require investigation. MATERIALS AND METHODS: This study involved 1248, 431, and 323 patients with end-stage renal disease who had received an AVF, AVG, or CVC, respectively. All sampled patients were monitored over the course of a 1-y study period to evaluate their medical utilization. The utilization were further categorized into nephrology and nonnephrology services. This study also performed univariate and multivariate regressions to estimate the effects of vascular accesses. RESULTS: Regarding the utilization of health care services, significant differences were observed for mean outpatient visits (45.30 versus 49.71 versus 48.80), outpatient costs (US$19117 versus US$21015 versus US$19280), inpatient days (9.77 versus 14.41 versus 21.60), inpatient costs (US$2627 versus US$3810 versus US$5238), and total costs (US$21743 versus US$24825 versus US$24518) among patients who had received an AVF, AVG, or CVC, respectively. Furthermore, patients receiving an AVF had lower total costs for all health care services and nonnephrology services than patients undergoing AVG or CVC across the categories of men, women, adults, and elderly individuals. Multiple regressions found that patients undergoing AVF had significantly lower total costs for all health services than patients undergoing other vascular accesses after adjustments. CONCLUSIONS: This study displayed that patients who received an AVF fully used health care and nonnephrology services than patients who received an AVG or CVC.

Background: The extracorporeal life support (ECLS) and temporary bilateral ventricular assist device (t-BiVAD) are commonly applied in patients with cardiogenic shock. Prolonged cardiopulmonary resuscitation (CPR) has poor prognosis. Herein, we report our findings on a combined ECLS and t-BiVAD approach to salvage cardiogenic-shock patients with CPR for more than one hour. Methods: Fifty-nine patients with prolonged CPR and rescued by ECLS and subsequent t-BiVAD were retrospectively collected between January 2015 and December 2019. Primary diagnoses included ischemic, dilated cardiomyopathy, acute myocardial infarction, post-cardiotomy syndrome, and fulminant myocarditis. The mean LVEF was 16.9% ± 6.56% before t-BiVAD. The median ECLS-to-VAD interval is 26 h. Results: A total of 26 patients (44%) survived to weaning, including 13 (22%) bridged to recovery, and 13 (22%) bridged to transplantation. Survivors to discharge demonstrated better systemic perfusion and hemodynamics than non-survivors. The CentriMag-related complications included bleeding (n = 22, 37.2%), thromboembolism (n = 5, 8.4%), and infection (n = 4, 6.7%). The risk factors of mortality included Glasgow Coma Scale (Motor + Eye) ≤ 5, and lactate ≥ 8 mmol/L at POD-1, persistent ventricular rhythm or asystole, and total bilirubin ≥ 6 mg/dL at POD-3. Mortality factors included septic shock (n = 11, 18.6%), central failure (n = 10, 16.9%), and multiple organ failure (n = 12, 20.3%). Conclusions: Combined ECLS and t-BiVAD could be a salvage treatment for patients with severe cardiogenic shock, especially for those already having prolonged CPR. This combination can correct organ malperfusion and allow sufficient time to bridge patients to recovery and heart transplantation, especially in Asia, where donation rates are low, as well as intracorporeal VAD or total artificial heart being seldom available.
RESUMEN
The relationships between pelagic larval duration (PLD) and geographic distribution patterns or population genetic structures of fishes remain obscure and highly variable among species. To further understand the early life history of the tidepool snake moray Uropterygius micropterus and the potential relationship between PLD and population genetic structure of this species, otolith microstructure and population genetics based on concatenated mtDNA sequence (cytochrome b and cytochrome oxidase subunit I, 1,336 bp) were analyzed for 195 specimens collected from eight locations around the southern Ryukyu Islands, Taiwan, and the central Philippines. Eels with longer PLD and lower otolith growth rates were observed at relatively higher latitudes with lower water temperatures (54.6 ± 7.7 days and 1.28 ± 0.16 µm day-1 on Ishigaki Island, Japan, vs. 43.9 ± 4.9 days and 1.60 ± 0.19 µm day-1 on Badian, the Philippines), suggesting that leptocephali grew faster and had shortened pelagic periods in warmer waters. Meanwhile, the eels along the southwest coast of Taiwan had relatively longer PLD (57.9 ± 10.5 days), which might be associated with the more complex ocean current systems compared to their counterparts collected along the east coast of Taiwan (52.6 ± 8.0 days). However, the southwestern and eastern Taiwan groups had similar otolith growth rates (1.33 ± 0.19 µm day-1 vs. 1.36 ± 0.16 µm day-1). Despite the intergroup variation in PLD, genetic analysis revealed fluent gene flow among the tidepool snake morays in the study regions, implying that intraspecies PLD variation had a weak effect on genetic structure. The leptocephalus stage might have ensured the widespread gene flow among the study areas and leptocephalus growth was likely influenced by regional water temperature.
