    This research aimed to know the growth rate of seaweed (Kappaphycus alvarezii) cultivated by using off bottom method and long line method in coastal waters Tita Dwiwarna Village Banda Central of Maluku. It is expected that this research will provide basic information in business of seaweed cultivation to be developed. The methods were off bottom method and long line method that consisted of 2 treatments and 3 replications. Material used was mostly a polyethylene rope as long as 10 meters with the diameter size 5 mm for a mine rope and 3 mm for a span rope. Initial weight of sea weeds which is tied to a span rope 100 gram. The growth data collection was taken simultaneously with water quality data every week. Data were analyzed by using Cohran test to see homogeneity. The homogeneity data were then analyzed by using t-test to see the different between two treatments. The result of the research has shown that seaweed growth was highest in off bottom methods which average weight on the seventh week reached 690 gram. While the growth with long line methods reached the average weight on the seventh week reached only 609.4 gram. Therefore, the best growth of the sea weed was represented by off bottom method

    OBJECTIVES: This study sought to evaluate the differences in cardiogenic shock patient characteristics in trial patients and real-life patients. BACKGROUND: Cardiogenic shock (CS) is a leading cause of mortality in patients presenting with acute myocardial infarction (AMI). However, the enrollment of patients into clinical trials is challenging and may not be representative of real-world patients. METHODS: We performed a systematic review of studies in patients presenting with AMI-related CS and compared patient characteristics of those enrolled into randomized controlled trials (RCTs) with those in registries. RESULTS: We included 14 RCTs (n = 2,154) and 12 registries (n = 133,617). RCTs included more men (73% vs 67.7%, P \u3c 0.001) compared with registries. Patients enrolled in RCTs had fewer comorbidities, including less hypertension (61.6% vs 65.9%, P \u3c 0.001), dyslipidemia (36.4% vs 53.6%, P \u3c 0.001), a history of stroke or transient ischemic attack (7.1% vs 10.7%, P \u3c 0.001), and prior coronary artery bypass graft surgery (5.4% vs 7.5%, P \u3c 0.001). Patients enrolled in RCTs also had lower lactate levels (4.7 ± 2.3 mmol/L vs 5.9 ± 1.9 mmol/L, P \u3c 0.001) and higher mean arterial pressure (73.0 ± 8.8 mm Hg vs 62.5 ± 12.2 mm Hg, P \u3c 0.001). Percutaneous coronary intervention (97.5% vs 58.4%, P \u3c 0.001) and extracorporeal membrane oxygenation (11.6% vs 3.4%, P \u3c 0.001) were used more often in RCTs. The in-hospital mortality (23.9% vs 38.4%, P \u3c 0.001) and 30-day mortality (39.9% vs 45.9%, P \u3c 0.001) were lower in RCT patients. CONCLUSIONS: RCTs in AMI-related CS tend to enroll fewer women and lower-risk patients compared with registries. Patients enrolled in RCTs are more likely to receive aggressive treatment with percutaneous coronary intervention and extracorporeal membrane oxygenation and have lower in-hospital and 30-day mortality

    Modeling the behavior of radially pinned brick triplets

    Get PDF
    The continued use of many UK highway and railway masonry arch bridges is dependent upon maintaining robustness as the materials deteriorate over time. A common failure in multi-ring brickwork arches subject to fatigue, is ring separation. This paper offers some early results from an investigation of a ring separation repair technique involving radial pinning. Triplet testing is used to establish and compare the structural behavior of two types of shear reinforcement, which are validated by finite element modelling. Conclusions are drawn which are potentially of significant practical interest to masonry arch bridge owners and assessors

    CRT-700.05 Impella Utilization in High-Risk Percutaneous Coronary Intervention Mitigates the Risks of Procedural and Clinical Adverse Events Independent of Left Ventricular Ejection Fraction: The Protect III Study

    Get PDF
    Background: Left ventricular (LV) dysfunction is associated with an increased risk of adverse events in patients undergoing percutaneous coronary intervention (PCI). However, the impact of LV ejection fraction (LVEF) on the outcomes of Impella-supported high-risk PCI (HRPCI) is unknown. Methods: Patients enrolled in the prospective, multicenter, and observational PROTECT III study from March 2017 to March 2020 who underwent Impella-supported HRPCI at the operator’s discretion (non-cardiogenic shock). Patients were divided into three tertiles (T) based on baseline LVEF: T1 (the lowest), T2, and T3 (the highest). The primary outcome is the rate of 90-day major adverse cardiac and cerebrovascular events (MACCE), defined as the composite of all-cause death, myocardial infarction, stroke/transient ischemic attack, and repeated revascularization as adjudicated by an independent CEC. Results: Of 1237 patients, 940 with available baseline LVEF were analyzed. T1 included 353 patients (mean LVEF 19.6±4.7), T2 included 274 patients (mean LVEF 32.2±3.5), and T3 included 313 patients (mean LVEF 52.6±9.2). Patients in the higher tertiles were older, more likely to be females, presented more with acute coronary syndrome, and had more frequent left main disease. Also, severely calcified lesions and atherectomy utilization were more frequent in the higher tertiles. The rates of 90-day MACCE were comparable across all tertiles. Furthermore, PCI-related complications and 1-year mortality were also comparable (Table). After multivariable adjustment, 90-day MACCE was not significantly different between the LVEF tertiles (p=0.32). Conclusion: In patients with HRPCI supported by Impella, the rates of in-hospital adverse events, PCI-related complications, 90-day MACCE, and 1-year mortality were comparable among the different LVEF tertiles

    Tissue Harvester with Functional Valve (THFV): Shidham's device for reproducibly higher specimen yield by fine needle aspiration biopsy with easy to perform steps

    BACKGROUND: Fine needle aspiration biopsy (FNAB) cytology has been a highly effective methodology for tissue diagnosis and for various ancillary studies including molecular tests. In addition to other benefits, FNAB predominantly retrieves the diagnostic loosely cohesive cells in the lesion as compared to the adjacent supporting stroma with relatively higher cohesiveness. However, FNAB procedure performed with currently available resources is highly skill dependent with inter-performer variability, which compromises its full potential as a diagnostic tool. In this study we report a device overcoming these limitations. METHODS: 'Tissue Harvester with Functional Valve' (THFV) was evaluated as part of a phase 1 National Institute of Health (NIH) research grant under Small Business Technology Transfer (STTR) Program. Working prototypes of the device were prepared. Each of the four cytopathologists with previous cytopathology fellowship training and experience in performing FNAB evaluated 5 THFV and 5 hypodermic needles resulting in 40 specimens (20 with THFV, 20 with hypodermic needles). A piece of fresh cattle liver stuffed in latex glove was used as the specimen. Based on these results a finished design was finalized. RESULTS: The smears and cell blocks prepared from the specimens obtained by THFV were superior in terms of cellularity to specimens obtained with hypodermic needles. The tissuecrit of specimens obtained with THFV ranged from 70 to 100 μl (mean 87, SD 10), compared to 17 to 30 μl (mean 24, SD 4) with conventional hypodermic needles (p < .0001, Student t-test). The technical ease [on a scale of 1 (easy) to 5 (difficult)] with THFV ranged from 1 to 2 as compared to 2 to 3 with hypodermic needles. CONCLUSION: The specimen yield with the new THFV was significantly higher when compared to hypodermic needles. Also, the FNAB procedure with THFV was relatively easier in comparison with hypodermic needles. The final version of Shidham's THFV device would improve the FNAB specimen yield by eliminating the skill factor. The increased specimen yield by this device would also facilitate wider application of FNAB specimens for various ancillary tests, including molecular tests
