卫生应急人员对突发事件风险评估的认知分析

目的 :了解我国卫生应急人员对突发公共卫生事件风险评估的认知状况,从文化程度、职称情况、单位性质、单位级别等方面进行比较,为提高卫生应急人员风险评估的认识和能力提供依据。方法 :采用问卷调查的方法,对全国(大陆地区)31个省(自治区、直辖市)承担突发公共卫生事件应急处置的卫生应急工作人员进行调查。采用描述性分析和χ2检验对调查数据进行分析。结果 :我国卫生应急人员对风险评估概念熟悉程度较低,且不同学历、不同职称、不同工作年限、不同机构、不同层级之间的认知存在一定差异;对风险评估工作内容的认知也存在分歧。结论 :应加强风险评估培训,健全风险评估制度,以全面提高卫生应急人员对风险评估的认知水平。     

Laser tongue debridement for oral malodor—A novel approach to halitosis

Study objectiveMalodor is a multifactorial condition with oral pathology representing the main culprit and the tongue being the first to second contributor to the malodor. Bacterial load can represent a quantifiable measure regardless of the original pathology. We hypothesize that reduction in malodor can be represented by tongue changes both in appearance, bacterial and biofilm load reduction (measured by CFU and volatile gases measurement), organoleptic measurement and subjective improvement.MethodsA randomized controlled prospective study under IRB approval. Diagnostic criteria for enrollment and follow up were organoleptic test by 2 judges, Halimeter reading, tongue colors changes HALT questionnaire and direct aerobic and anaerobic tongue cultures measured by CFU. Patients were treated with laser tongue debridement (LTD) with an Er,Cr:YSGG solid state laser has been shown to be effective in biofilm reduction.Results54 patients recruited with 35 available for follow up. Improvement was observed on all objective and QOL subjective parameters. Treatment was tolerated well with minimal discomfort.ConclusionsThe tongue is proven to be a major contributor to oral malodor and must be addressed in treatment protocol. LTD significantly reduces malodor by subjective and objective criteria. While impossible to determine whether the tongue serves as a bacterial reservoir or is the origin for oral bacteria it is clear that LTD improves oral hygiene and reduces malodor. LTD is safe and easy to perform. We encourage LTD to be a crucial part of any oral malodor treatment protocol.Trial registration: clinical trials, NCT04120948.

Practical aspects of electrophoretic deposition to produce commercially viable supercapacitor energy storage electrodes

Electrophoretic deposition (EPD) is a highly convenient and demonstrated industrial operation for the manufacture of surface coatings. Recent years are seeing increasing evidence in using this technique to produce energy storage electrodes (notably for lithium-ion batteries, solid-state devices, supercapacitors, and flow batteries), but their advancement for industrialisation remains unclear. Using activated carbon (AC) as an exemplary supercapacitor material, this study reports the practical aspects of porous energy storage electrodes produced by the EPD technique. Practical electrodes with commercially viable parameters are shown, specifically high density active material (in excess of 9.8 mg cm⁻²) and very thick coating layer (about 168 μm). Research investigations including colloidal electrolyte formulations, electrode deposition parameters and cell performance testing are reported. Materials and electrode properties were studied by various charactersisation tools. Prototype A7 sized pouch cells were assembled and tested to show evidence of practical EPD electrodes in a commercial cell format. Electrochemical performance of EPD over slurry casting is presented. In short, this research shows the successful production of practical EPD electrodes for electrochemical energy storage, which is directly relevant for scale-up industrial adoption and can be applied as a platform electrode manufacturing technology for any battery and supercapacitor materials.

Electrophoretic deposition (EPD) is a highly convenient and demonstrated industrial operation for coatings manufacture. It is now suitable for the production of practical energy storage electrodes for batteries, capacitors & solid-state devices.

Electrophysiological studies on the effect of age on caudal nerve of the rat

The effect of age on electrophysiologic parameters was studied on the caudal nerve of 374 male Sprague-Dawley rats (age 24 to 630 days) and on 83 Fischer 344 rats (age 29 to 900 days). For Sprague-Dawley rats nerve conduction velocity and nerve action potential amplitude were both a parabolic function of age, increasing to 1 year and then declining. For Fischer 344 rats the same parameters increased progressively to 1.5 years and then declined. In contrast, for both Sprague-Dawley and Fischer 344 rats, resistance to ischemic conduction failure was a hyperbolic function of age reaching an asymptote at 1.5 to 2 years of age. These age-related changes in caudal nerve parallel the electrophysiologic alterations with age in human peripheral nerve more closely than previous reports in rodent limb nerves.     

Pseudo-no-reflow phenomenon in ostial saphenous vein graft intervention using FilterWire EX protection

Distal protection using FilterWire EX has been shown to be effective in reducing the incidence of debris embolization and no-reflow phenomenon in saphenous vein graft (SVG) intervention. We present a case of mechanical obstruction of antegrade flow by atherothrombotic debris collected in the FilterWire EX after stent implantation of the ostial SVG lesion, masqueraded as no-reflow phenomenon. The condition was promptly reverted by thrombosuction using an Export Aspiration Catheter. A heavy debris burden was recovered by the thrombosuction and there was no evidence of myonecrosis after the procedure. We emphasize that different distal protection device can complement each other in special situations. A brief overview of the various approaches in preventing distal embolization in SVG intervention was also given.
