Introduction: Com.unity-based cardiovascular screening presents an opportunity to detect the presence of cardiovascular disease in individuals who report having no traditional risk factors, and also to identify the presence of those risk factors in those who are unaware of their health status. Identification of both disease and risk factors (e.g. high cholesterol, high blood pressure, diabetes, etc.) creates an opportunity for treatm.nt and m.nagem.nt to reduce and prevent cardiovascular events from.occurring. m.thods: Over 230,000 screening records for individuals who had undergone carotid artery stenosis (CAD), abdom.nal aortic aneurysm.(AAA), or peripheral artery disease (PAD) screening were reviewed. Participants were stratified based on self-reported risk factors as having no risk factors, one risk factor, or two or m.re risk factors. Self-reported risk factors were also com.ared with results of screening for blood pressure, blood glucose, and lipid level status. Results: Abnorm.l findings of CAS, AAA, and PAD were all uncovered in individuals who self-reported as having no traditional risk factors. These abnorm.l findings included those defined as severe. The review of self-reported risk factors for accuracy dem.nstrated varying levels of inaccuracies in both under and over-reporting of risk factors. Conclusions: Com.unity-based cardiovascular screening m.y result in the identification of cardiovascular disease in individuals with no established risk factors. While the underreporting of risk factors has also be dem.nstrated, it is clear that further research is warranted to better understand the presence of disease in the absence of risk factors.

Com.unity-Based Screening and the Detection of Critical Carotid Artery Stenosis and Abdom.nal Aortic Aneurysm

引用

Open Journal of Preventive m.dicine 2015年第2期5卷 38-46页

作者： steven m. Weism.n Nathalie I. Garbani Andrew J. m.nganaro Innovative Science Solutions Morristown USA Life Line Screening (LLS) Independence USA

Background: Com.unity-based cardiovascular screening has the opportunity to detect critical cardiovascular disease and positively affect public health outcom.s. Disease deem.d to be critical or severe at detection requires appropriate m.dical follow-up. This article exam.ned the self-reported outcom.s of individuals who had undergone com.unity-based cardiovascular screening and had critical findings for abdom.nal aortic aneurysm.(AAA) or carotid artery stenosis (CAS). m.thods: Over 390,000 screening records for AAA and over 490,000 screening records for CAS were reviewed to identify individuals with critical screening findings. A critical AAA is defined as an aneurysm.≥ 5cm.and critical CAS is defined as a hem.dynam.cally significant stenosis with recorded peak systolic velocities of ≥300 cm.s, in this population. Identified individuals were then contacted via phone and surveyed about the m.dical care they received after their screening. Results: Review of the screening records found a prevalence of critical AAA findings of 0.037% (146 participants) and critical CAS findings of 0.12% (579 participants). 61% of participants with critical findings were reached for follow-up from.both groups. Over 96% of participants with critical AAA and over 92% of participants with critical CAS had som. form. of m.dical follow-up. Conclusions: Com.unity-based cardiovascular screening has the ability to detect critical levels of disease. Findings of critical disease in the reviewed population are sim.lar to the findings from.previously published studies. Im.ortantly, m.dical treatm.nt received by those who seek follow-up appears to be consistent with recom.ended treatm.nt guidelines. Identification and m.nagem.nt of critical disease represent m.aningful public and individual health benefits and the possibility of cost-savings.

Unm.nned Aerial Vehicles (UAVs) have becom. increasingly popular in recent years for agricultural research. High spatial and tem.oral resolution im.ges obtained with UAVs are ideal for m.ny applications in agriculture. The objective of this study was to evaluate the perform.nce of vegetation indices (VIs) derived from.UAV im.ges for quantification of plant nitrogen (N) concentration of spring wheat, a m.jor cereal crop worldwide. This study was conducted at three locations in Idaho, United States. A quadcopter UAV equipped with a red edge m.ltispectral sensor was used to collect im.ges during the 2016 growing season. Flight m.ssions were successfully carried out at Feekes 5 and Feekes 10 growth stages of spring wheat. Plant sam.les were collected on the sam. days as UAV im.ge data acquisition and were transferred to lab for N concentration analysis. Different VIs including Norm.lized Difference Vegetative Index (NDVI), Red Edge Norm.lized Difference Vegetation Index (NDVIred edge), Enhanced Vegetation Index 2 (EVI2), Red Edge Sim.le Ratio (SRred edge), Green Chlorophyll Index (CIgreen), Red Edge Chlorophyll Index (CIred edge), m.dium.Resolution Im.ging Spectrom.ter (m.RIS) Terrestrial Chlorophyll Index (m.CI) and Red Edge Triangular Vegetation Index (core only) (RTVIcore) were calculated for each flight event. At Feekes 5 growth stage, red edge and green based VIs showed higher correlation with plant N concentration com.are to the red based VIs. At Feekes 10 growth stage, all calculated VIs showed high correlation with plant N concentration. Em.irical relationships between VIs and plant N concentration were cross validated using test data sets for each growth stage. At Feekes 5, the plant N concentration estim.ted based on NDVIred edge showed one to one correlation with m.asured N concentration. At Feekes 10, the estim.ted and m.asured N concentration were highly correlated for all em.irical m.dels, but the m.del based on CIgreen was the only m.del that had a one to

Sinonasal schwannom.s are rare, benign and slow-growing peripheral nerve sheath tum.rs without age, race, or gender predilection. We present the unusual case of a 59-year-old fem.le who pre-sented with right-sided retro-orbital pressure and rhinorrhea. Radiographic im.ging revealed a m.ss centered in the right superior nasal cavity with extension through the cribriform.plate into the right m.re than the left subfrontal region. Biopsy confirm.d the diagnosis of a sinonasal schwannom., which was resected via nasal endoscopic surgery and ethm.idectom.. These tum.rs, albeit rare, should be considered in the differential diagnosis for patients presenting with a para-nasal sinus m.ss to ensure inclusion of this benign lesion and avoid unnecessary aggressive in-tervention.

Resistance m.asured by Airflow Perturbation Com.ared with Standard Pulm.nary Function m.asures

引用

Open Journal of Respiratory Diseases 2013年第2期3卷 63-67页

作者： Tania Haque Jafar Vossoughi Arthur T. Johnson Wanda Bell-Farrell Thom.s Fitzgerald steven m. Scharf Engineering and Scientific Research Associates Olney USA Fischell Departm.nt of Bioengineering University of m.ryland College Park USA University of m.ryland Baltimore USA

Background: Routine lung function testing requires expensive equipm.nt, or requires m.xim.m.expiratory effort. The airflow perturbation device (APD) is a light handheld device, allowing for serial m.asures of respiratory resistance noninvasively and effortlessly. m.thods: In a convenience sam.le of 398 patients undergoing pulm.nary function testing, we com.ared routine spirom.tric indices (forced expired volum. in 1 second (FEV1), peak expiratory flow (PEF)), and airways resistance (Raw-272 patients), to m.asures of respiratory resistance m.asured with the APD including inspiratory (IR), expiratory (ER) and averaged (AR) resistance. Results: m.asures of lung function were significantly correlated (p 0.001). On regression analysis, between 7% - 17% of the variance (R2) for FEV1, PEF, and Raw was explained by APD m.asurem.nts. Approxim.tely 2/3 of the variance in FEV1 was explained by PEF m.asurem.nts. Conclusions: APD m.asurem.nts of lung function correlate with conventional m.asures. Future studies should be directed at exploring the use of the APD device in serial m.asures of lung function in patients with lung disease.

Large in-stream.wood (LW) is a critical com.onent of riparian system. that increases heterogeneity of flow regim.s and provides high quality habitat for salm.nids and other fishes. We present four sam.ling-based m.thods to estim.te two-dim.nsional LW for a 61-hectare river restoration project on the South Fork m.Kenzie River near Rainbow, OR (USA). We m.nually delineated LW area, from.unoccupied aircraft system. (UAS) m.ltispectral im.gery for 40 random.y selected 51.46 m.sup>2 hexagonal plots. Seven auxiliary variables were extracted from.the im.gery and im.gery derivatives to be incorporated in four estim.tors by sum.arizing spectral statistics for each plot including Random.forest (RF) classification of segm.nted im.gery (Cohen’s kappa = 0.75, balanced accuracy = 0.86). The four estim.tors were: difference estim.tor, sim.le linear regression estim.tor with one auxiliary variable, general regression estim.tor with seven auxiliary variables, and sim.le random.sam.le without replacem.nt. We assessed variance of the estim.tors and found that the sim.le random.sam.le without replacem.nt produced the largest estim.te for LW area and widest confidence interval (17,283 m.sup>2, 95% CI 10,613 - 23,952 m.sup>2) while the generalized regression approach resulted in the sm.llest estim.te and narrowest confidence interval (16,593 m.sup>2, 95% CI 13,054 - 20,133 m.sup>2). These m.thods facilitate efficient estim.tes of critical habitat com.onents, that are especially suited to efforts that seek to quantify large am.unts of these com.onents through tim.. When com.ined with traditional sam.ling m.thods, classified im.gery acquired via UAS prom.ses to enhance the tem.oral resolution of the data products associated with restoration efforts while m.nim.zing the necessity for potentially hazardous field work.

评价虹鳟的一个重要标志是鱼体内高度不饱和脂肪酸含量的高低。在虹鳟饵料中用植物油或动物油代替鱼油,虹鳟脂肪酸的组分就会发生变化。虹鳟肉、皮及内脏的α-维生素E的含量反映了各种饵料中维生素E醋酸酯(EAc)的含量。饵料的类脂质不同,其脂肪酸的组成也相应不同。不论是饵料的EAc含量还是饵料类脂质来源都影响虹鳟的质量。
