Background Radiofrequency catheter ablation (RFCA) using the high‐power short duration (HPSD) results in better ablation lesion formation in the swine model. This systematic review and meta‐analysis purposed to investigate the safety and efficacy profile between HPSD and low‐power long‐duration (LPLD) ablation strategies to treat atrial fibrillation (AF) patients. Methods We completed the literature review after identifying the relevant articles comparing HPSD and LPLD ablation methods for AF recorded in ClinicalTrials.com, CENTRAL, PubMed, and ScienceDirect until February 2021. The overall effects were calculated using pooled risk ratio (RR) and mean difference (MD) for categorical and continuous data, respectively. We also estimated the 95% confidence interval (CI). Results The HPSD strategy took shorter procedure time (MD = −33.75 min; 95% CI = −44.54 to −22.97; P < .01), fluoroscopy time (MD = −5.73 min; 95% CI = −8.77 to −2.70; P < .001), and ablation time (MD = −17.71; 95% CI = −21.02 to −14.41) than LPLD strategy. The HPSD RFCA was correlated with lower risk of esophageal thermal injury (RR = 0.75; 95% CI = 0.59 to 0.94; P = .02). The HPSD method resulted in higher first‐pass pulmonary vein isolation (PVI) (RR = 1.36; 95% CI = 1.13 to 1.64; P < .01), lower PV reconnection (RR = 0.47; 95% CI = 0.34 to 0.64; P < .01), and lower recurrent AF (RR = 0.72; 95% CI = 0.54 to 0.96; P = .02) than LPLD strategy. Conclusion HPSD RFCA was superior to the conventional LPLD RFCA in terms of safety and efficacy in treating AF patients.
The major obstacles in the development of broiler raising is the expensive price of feed and the fl uctuative price of DOCs. The cheap price of imported leg quarters reduces the competitiveness of the local broilers. Therefore, an eff ort to increase production effi ciency is needed through integration between broiler raising and corn farmers and feed producers (integrated farming). The purpose of this study is to analyze the feasibility of integrating broiler raising with corn cultivation and feed production. Besides that, a simulation was conducted to analyze the eff ects of DOC price changes, broiler price and production capacity. The analyses showed that integrated farming and a mere combination between broiler raising and feed factory of a 10,000 bird capacity is not fi nancially feasible. Increasing the production to 25,000 broiler chickens will make the integrated farming fi nancially feasible. Unintegrated broiler raising is relatively sensitive to broiler price decreases and DOC price increases compared to integrated farming.
<em>Red chili is known as a very high commodity price fluctuation. High price fluctuation will make market inefficiency and cause a disincentive for market actors. One indicator of market efficiency is symmetric price transmission in integrated market. This paper aimed to analyze vertical price transmission along the marketing chanel of red chili (produsen, wholesale and retail) and analyze the market behavior of market actors. Vertical price transmission was analyzed with the Asymmetric Error Corection Model (AECM) approach using weekly data over Januari 2012 to October 2014. While, the market behavior was analized using descriptive analysis with sequentil bargaining game. The results showed that price transmission along marketing channel of red chili is symmetric and the price in wholesale is a reference for produsen dan retail prices.</em>
Sandfish Holothuria scabra is a promising aquaculture commodity. Techniques for producing this species have been developed rapidly in recent decades to address the issues of increasing market demand and overexploitation of wild populations. Providing sandfish seed with suitable size for stocking (20-50 g) is one of the main issues in mass production of sandfish. Developing reliable nursery techniques could solve this problem. This study aimed to investigate the survival and growth performance of sandfish juveniles in two types of nursery cage: (i) floating net cages and (ii) fixed net cages. The experiments were conducted in a tidal earthen seawater pond in Sekotong, West Lombok for 14 weeks between August 5 and November 13, 2015. Each type of experimental cage had 3 replicates, stocked with 15 juveniles (mean initial weight 4.22 g) per cage. Feed was provided naturally from the substrate in the pond and in seawater, which was exchanged daily following the natural tidal cycle. Juveniles showed rapid growth and high survival rate for both floating and fixed net cages during the first six weeks of culture with no significant difference (P<0.05). Conversely, at the end of the experiment, the growth and survival of juveniles in the fixed net cage were lower because of the extreme low tide and the dry season, which began after week 6. During the low tide, floating net cages stayed submerged in the water while some parts of the fixed cages were exposed, killing the juveniles attached to the net. Our findings suggest that both cages were suitable for use in sandfish juvenile nurseries, although it is better to use the floating net cage in tidal ponds.
Atherosclerotic cardiovascular diseases (CVDs) are the leading cause of death and disability in the United States. While multiple studies have demonstrated that modification of atherosclerotic cardiovascular risk factors (CVRFs) significantly reduces morbidity and mortality rates, clinical control of CVDs and CVRFs remains poor. By 2010, the American Heart Association seeks to reduce coronary heart disease, stroke, and risk by 25%. To meet this goal, clinical practitioners must establish new treatment paradigms for CVDs and CVRFs. This paper discusses one such treatment model – a comprehensive atherosclerosis program run by physician extenders (under physician supervision), which incorporates evidence-based CVD and CVRF interventions to achieve treatment goals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
