Seafood is currently the best and generally a safe source of long-chain (LC, (≥C(20)) omega-3 oils amongst the common food groups. LC omega-3 oils are also obtained in lower amounts per serve from red meat, egg and selected other foods. As global population increases the opportunities to increase seafood harvest are limited, therefore new alternate sources are required. Emerging sources include microalgae and under-utilized resources such as Southern Ocean krill. Prospects for new land plant sources of these unique and health-benefiting oils are also particularly promising, offering hope for alternate and sustainable supplies of these key oils, with resulting health, social, economic and environmental benefits.

Beyond landraces: developing improved germplasm resources for underutilized species - a case for Bambara groundnut.

The potential for underutilized crops (also known as minor, neglected or orphan crops) to improve food and nutrition security has been gaining prominence within the research community in recent years. This is due to their significance for diversified agricultural systems which is a necessary component of future agriculture to address food and nutritional security concerns posed by changing climate and a growing world population. Developing workable value chain systems for underutilized crop species, coupled with comparative trait studies with major crops, potentially allows us to identify suitable agricultural modalities for such species. Bambara groundnut (Vigna subterranea L. Verdc.), an underutilized leguminous species, is of interest for its reported high levels of drought tolerance in particular, which contributes to environmental resilience in semi-arid environments. Here, we present a synopsis of suitable strategies for the genetic improvement of Bambara groundnut as a guide to other underutilized crop species. Underutilized crops have often been adapted over thousands of years in particular regions by farmers and largely still exist as landraces with little or no genetic knowledge of key phenotypic traits. Breeding in these species is fundamentally different to breeding in major crops, where significant pedigree structures and history allow highly directed improvement. In this regard, deploying new integrated germplasm development approaches for variety development and genetic analysis, such as multi-parent advance generation inter-crosses (MAGIC), within breeding programmes of underutilized species will be important to be able to fully utilize such crops.

Abstract Ultrasound-guided renal access for percutaneous nephrolithotomy (PCNL) is a safe, effective, and low-cost procedure commonly performed worldwide, but a technique underutilized by urologists in the United States. The purpose of this article is to familiarize the practicing urologist with methods for ultrasound guidance for percutaneous renal access. We discuss two alternative techniques for gaining renal access for PCNL under ultrasound guidance. We also describe a novel technique of using the puncture needle to reposition residual stone fragments to avoid additional tract dilation. With appropriate training, ultrasound-guided renal access for PCNL can lead to reduced radiation exposure, accurate renal access, and excellent stone-free success rates and clinical outcomes.

The leading cause of adult injury death in the U.S.A. is drug overdose, the majority of which involves prescription opioid medications. Outside of the U.S.A., deaths by drug overdose are also on the rise, and overdose is a leading cause of death for drug users. Reducing overdose risk while maintaining access to prescription opioids when medically indicated requires careful consideration of how opioids are prescribed and dispensed, how patients use them, how they interact with other medications, and how they are safely stored. Pharmacists, highly trained professionals expert at detecting and managing medication errors and drug-drug interactions, safe dispensing, and patient counseling, are an under-utilized asset in addressing overdose in the U.S. and globally. Pharmacies provide a high-yield setting where patient and caregiver customers can access naloxone-an opioid antagonist that reverses opioid overdose-and overdose prevention counseling. This case study briefly describes and provides two US state-specific examples of innovative policy models of pharmacy-based naloxone, implemented to reduce overdose events and improve opioid safety: Collaborative Pharmacy Practice Agreements and Pharmacy Standing Orders.

The role of underutilized fruits in nutritional and economic security of tribals: a review.

PubMed

Nandal, Urvashi; Bhardwaj, Raju Lal

2014-01-01

The tribal people of Rajasthan are severely malnourished along with multiple nutrient-deficiency disorders due to ignorance about importance of fruits and vegetables in their diets. The tribal areas are full of biodiversity having natural vegetation which is not harnessed fully. Due to which a wide gap is formed between health and optimal use of natural sources of nutrients, i.e., underutilized crops. The crops, which are neither grown commercially on large scale nor traded widely, may be termed as underutilized horticultural crops. These crops are cultivated, traded, and consumed locally. These crops have many advantages like easier to grow and hardy in nature, producing a crop even under adverse soil and climatic conditions. So, exploitation of underutilized horticultural crops can become a solution to the social problem of health and nutrition insecurity, poverty, and unemployment. The consumption of underutilized fruit crops can provide nutrition to the poor and needy tribals by meeting the nutrient requirements of vulnerable groups. As underutilized fruits, nuts, and vegetables are a rich of source of carbohydrates, fats, proteins, energy, vitamins-A, B1, B2, B3, B6, B9, B12, C, folic acid, and minerals-Ca, P, Fe, and dietary fiber. Thus, they have the nutritional capacity to prevent and cure various diseases like kwashiorkor, marasmus, night blindness, anemia, diabetes, cancer, hypertension, and hidden hunger. It is also established fact that seasonal, locally available, and cheap fruits and vegetables can also keep the population healthy and nutritionally secure rather than costly off-season ones. Also, the underutilized crops have the potential to give economic security to tribals by giving employment and by fetching good returns from their sale in raw form as well as value-added products.

The anaerobic threshold: over-valued or under-utilized? A novel concept to enhance lipid optimization!

PubMed

Connolly, Declan A J

2012-09-01

The purpose of this article is to assess the value of the anaerobic threshold for use in clinical populations with the intent to improve exercise adaptations and outcomes. The anaerobic threshold is generally poorly understood, improperly used, and poorly measured. It is rarely used in clinical settings and often reserved for athletic performance testing. Increased exercise participation within both clinical and other less healthy populations has increased our attention to optimizing exercise outcomes. Of particular interest is the optimization of lipid metabolism during exercise in order to improve numerous conditions such as blood lipid profile, insulin sensitivity and secretion, and weight loss. Numerous authors report on the benefits of appropriate exercise intensity in optimizing outcomes even though regulation of intensity has proved difficult for many. Despite limited use, selected exercise physiology markers have considerable merit in exercise-intensity regulation. The anaerobic threshold, and other markers such as heart rate, may well provide a simple and valuable mechanism for regulating exercising intensity. The use of the anaerobic threshold and accurate target heart rate to regulate exercise intensity is a valuable approach that is under-utilized across populations. The measurement of the anaerobic threshold can be simplified to allow clients to use nonlaboratory measures, for example heart rate, in order to self-regulate exercise intensity and improve outcomes.

CRM training can be done on a limited budget. It seems that everyone has a special name for their CRM program. A new program was created and entitled, Aircrew Resource Management (ARM) to emphasize the use of the full resources on our aircraft. That is meant to specifically include the loadmasters. The name also emphasizes the concept that all crewmembers are responsible for safe completion of the trip. The loadmasters have been the brightest students to date. They are a classic under-utilized resource. Together, their crew position has been credited with more ARM saves than the engineers and pilots. The seminar-based program is run by two seminar facilitators that is reinforced by Line Oriented Flight Training sessions run by the active-duty counterparts.

The surgical treatment of cervical radiculopathy has centered around anterior cervical discectomy and fusion (ACDF). Alternatively, the posterior cervical laminoforaminotomy/microdiscectomy (PCF/PCM), which results in comparable outcomes and is more cost-effective, has been underutilized. Here, we compared the direct/indirect costs, reoperation rates, and outcome for ACDF and PCF vs. PCM using PubMed, Medline, and Embase databases. There were no significant differences between the re-operative rates of PCF/PCM (2% to 9.8%) versus ACDF (2% to 8%). Direct costs of ACDF were also significantly higher; the 1-year cost-utility analysis demonstrated that ACDF had $131,951/QALY while PCM had $79,856/QALY. PCF/PCM for radiculopathy are safe and more cost-effective vs. ACDF, and have similar clinical outcomes.

To all peoples in all parts of the world throughout history, the ability to move about easily is a fundamental element of freedom. The American people have charged NASA to increase their freedom and that of their children knowing that their quality of life will improve as our nation s transportation systems improve. In pursuit of this safe, reliable, and affordable personalized air transportation option, in 2000 NASA established the Small Aircraft Transportation System (SATS) Project. As the name suggests personalized air transportation would be built on smaller aircraft than those used by the airlines. Of course, smaller aircraft can operate from smaller airports and 96% of the American population is within thirty miles of a high-quality, underutilized community airport as are the vast majority of their customers, family members, and favorite vacation destinations.

2015-01-01

Various plastic strips and sheets (termed ‘simple anterior fish excluders’−SAFEs) were positioned across the openings of penaeid trawls in attempts at reducing the unwanted bycatches of small teleosts. Initially, three SAFEs (a single wire without, and with small and large plastic panels) were compared against a control (no SAFE) on paired beam trawls. All SAFEs maintained targeted Metapenaeus macleayi catches, while the largest plastic SAFE significantly reduced total bycatch by 51% and the numbers of Pomatomus saltatrix, Mugil cephalus and Herklotsichthys castelnaui by up to 58%. A redesigned SAFE (‘continuous plastic’) was subsequently tested (against a control) on paired otter trawls, significantly reducing total bycatch by 28% and P. saltatrix and H. castelnaui by up to 42%. The continuous-plastic SAFE also significantly reduced M. macleayi catches by ~7%, but this was explained by ~5% less wing-end spread, and could be simply negated through otter-board refinement. Further work is required to refine the tested SAFEs, and to quantify species-specific escape mechanisms. Nevertheless, the SAFE concept might represent an effective approach for improving penaeid-trawl selectivity. PMID:25837892

Women who inject drugs (WWID) are at higher risk of HIV compared with their male counterparts as a result of multiple factors, including biological, behavioral, and sociostructural factors, yet comparatively little effort has been invested in testing and delivering prevention methods that directly target this group. In this article, we discuss the need for expanded prevention interventions for WWID, focusing on 2 safe, effective, and approved, yet underutilized biomedical prevention methods: opiate agonist therapy (OAT) and oral pre-exposure prophylaxis (PrEP). Although both interventions are well researched, they have not been well examined in the context of gender. We discuss the drivers of women injectors' higher HIV risk, review the effectiveness of OAT and PrEP interventions among women, and explain why these new HIV prevention tools should be prioritized for WWID. There is substantial potential for impact of OAT and PrEP programs for WWID in the context of broader gender-responsive HIV prevention initiatives. Although awaiting efficacy data on other biomedical approaches in the HIV prevention research "pipeline," we propose that the scale-up and implementation of these proven, safe, and effective interventions are needed now.

Introduction Sickle cell anemia (SCA) is a severe, inherited hemoglobin disorder affecting 100,000 persons in the US and millions worldwide. Hydroxyurea, a once daily oral medication, has emerged as the primary disease-modifying therapy for SCA. The accumulated body of evidence over 30 years demonstrates that hydroxyurea is a safe and effective therapy for SCA, but hydroxyurea remains underutilized for a variety of reasons. Areas covered In this review, we summarize the available evidence regarding the pharmacology, clinical, and laboratory benefits, and safety of hydroxy-urea therapy for the treatment of SCA. The purpose of this review is to provide the reader a comprehensive understanding of hydroxyurea and to reinforce the fact that hydroxyurea is a safe and effective medication for the treatment of SCA. Expert opinion In our opinion, hydroxyurea therapy should be considered standard-of-care for SCA, representing an essential component of patient management. Early initiation and broader use of hydroxyurea will alter the natural history of SCA, so affected children can live longer and healthier lives. In addition, hydroxyurea use should be extended to low-resource settings such as sub-Saharan Africa, where the burden of SCA and the need for hydroxyurea is arguably the greatest. PMID:26366626

Metastasis: recent discoveries and novel perioperative treatment strategies with particular interest in the hemostatic compound desmopressin.

2011-11-01

Metastatic disease is responsible for most of cancer lethality. A main obstacle for therapy of advanced cancers is that the outcome of metastasis depends on a complex interplay between malignant and host cells. The perioperative period represents an underutilized window of opportunity for cancer treatment where tumor-host interactions can be modulated, reducing the risk of local recurrences and distant metastases. Blood-saving agents are attractive compounds to be administered during tumor surgery. Desmopressin (DDAVP) is a safe and convenient hemostatic peptide with proved antimetastastic properties in experimental models and veterinary clinical trials. The compound seems to induce a dual angiostatic and antimetastatic effect, breaking the cooperative function of cancer cells and endothelial cells during residual tumor progression. DDAVP is therefore an interesting lead compound to develop novel synthetic peptide analogs with enhanced antitumor properties.

Affordable Launch Services using the Sport Orbit Transfer System

NASA Astrophysics Data System (ADS)

Goldstein, D. J.

2002-01-01

Despite many advances in small satellite technology, a low-cost, reliable method is needed to place spacecraft in their de- sired orbits. AeroAstro has developed the Small Payload ORbit Transfer (SPORTTM) system to provide a flexible low-cost orbit transfer capability, enabling small payloads to use low-cost secondary launch opportunities and still reach their desired final orbits. This capability allows small payloads to effectively use a wider variety of launch opportunities, including nu- merous under-utilized GTO slots. Its use, in conjunction with growing opportunities for secondary launches, enable in- creased access to space using proven technologies and highly reliable launch vehicles such as the Ariane family and the Starsem launcher. SPORT uses a suite of innovative technologies that are packaged in a simple, reliable, modular system. The command, control and data handling of SPORT is provided by the AeroAstro BitsyTM core electronics module. The Bitsy module also provides power regulation for the batteries and optional solar arrays. The primary orbital maneuvering capability is provided by a nitrous oxide monopropellant propulsion system. This system exploits the unique features of nitrous oxide, which in- clude self-pressurization, good performance, and safe handling, to provide a light-weight, low-cost and reliable propulsion capability. When transferring from a higher energy orbit to a lower energy orbit (i.e. GTO to LEO), SPORT uses aerobraking technol- ogy. After using the propulsion system to lower the orbit perigee, the aerobrake gradually slows SPORT via atmospheric drag. After the orbit apogee is reduced to the target level, an apogee burn raises the perigee and ends the aerobraking. At the conclusion of the orbit transfer maneuver, either the aerobrake or SPORT can be shed, as desired by the payload. SPORT uses a simple design for high reliability and a modular architecture for maximum mission flexibility. This paper will discuss the launch system and its application to small satellite launch without increasing risk. It will also discuss relevant issues such as aerobraking operations and radiation issues, as well as existing partnerships and patents for the system.

The suitability of several abundant but underutilized agro and forest based biomass residues for hydrothermal treatment followed by enzymatic hydrolysis as well as for hydrothermal carbonization was studied. The selected approaches represent simple biotechnical and thermochemical treatment routes suitable for wet biomass. Based on the results, the hydrothermal pre-treatment followed by enzymatic hydrolysis seemed to be most suitable for processing of carbohydrate rich corn leaves, corn stover, wheat straw and willow. High content of thermally stable components (i.e. lignin) and low content of ash in the biomass were advantageous for hydrothermal carbonization of grape pomace, coffee cake, Scots pine bark and willow.

Although the approach of contact network epidemiology has been increasing in popularity for studying transmission of infectious diseases in human populations, it has generally been an underutilized approach for investigating disease outbreaks in wildlife populations. In this paper we explore the differences between the type of data that can be collected on human and wildlife populations, provide an update on recent advances that have been made in wildlife epidemiology by using a network approach, and discuss why networks might have been underutilized and why networks could and should be used more in the future. We conclude with ideas for future directions and a call for field biologists and network modelers to engage in more cross-disciplinary collaboration. PMID:21527981

The primary aim of this study is to examine the prevalence of and antecedents to missing incidents among community-dwelling persons with dementia. This prospective study used mailed surveys and telephone interviews. The prevalence of having any incident was 0.46/year; the overall prevalence for missing incidents in this study was 0.65/year. Missing incidents had few antecedents and occurred largely when persons with dementia were performing everyday activities that they normally completed without incident. Given that a missing incident is relatively common among persons with dementia, health care professionals should assist caregivers with a missing incident plan early in the disease process. Also, as missing persons are found by persons other than the caregiver and caregivers underutilize identification devices, health care professionals may recommend the use of identification devices to facilitate a safe return.

Factors associated with underutilization of antenatal care services in Indonesia: results of Indonesia Demographic and Health Survey 2002/2003 and 2007

PubMed Central

2010-01-01

Background Antenatal care aims to prevent maternal and perinatal mortality and morbidity. In Indonesia, at least four antenatal visits are recommended during pregnancy. However, this service has been underutilized. This study aimed to examine factors associated with underutilization of antenatal care services in Indonesia. Methods We used data from Indonesia Demographic and Health Survey (IDHS) 2002/2003 and 2007. Information of 26,591 singleton live-born infants of the mothers' most recent birth within five years preceding each survey was examined. Twenty-three potential risk factors were identified and categorized into four main groups, external environment, predisposing, enabling, and need factors. Logistic regression models were used to examine the association between all potential risk factors and underutilization of antenatal services. The Population Attributable Risk (PAR) was calculated for selected significant factors associated with the outcome. Results Factors strongly associated with underutilization of antenatal care services were infants from rural areas and from outer Java-Bali region, infants from low household wealth index and with low maternal education level, and high birth rank infants with short birth interval of less than two years. Other associated factors identified included mothers reporting distance to health facilities as a major problem, mothers less exposed to mass media, and mothers reporting no obstetric complications during pregnancy. The PAR showed that 55% of the total risks for underutilization of antenatal care services were attributable to the combined low household wealth index and low maternal education level. Conclusions Strategies to increase the accessibility and availability of health care services are important particularly for communities in rural areas. Financial support that enables mothers from poor households to use health services will be beneficial. Health promotion programs targeting mothers with low education are vital to increase their awareness about the importance of antenatal services. PMID:20712866

Prior analyses show that warfarin is underutilized in most populations. To examine the use of antithrombotic and anticoagulant therapy in patients with atrial fibrillation or flutter during the index hospitalization for acute, ischemic stroke. Retrospective electronic medical record review of 200 patients treated at a tertiary care hospital with a primary ICD-9 code for ischemic stroke and a secondary ICD-9 code for atrial fibrillation or flutter. Exclusion criteria were active bleeding, pregnancy, age less than 18, pre-existing warfarin allergy, or dabigatran use. Fifty-two percent of patients received at least one dose of warfarin during the index hospitalization. There was no relationship between CHADS2 score and likelihood of receiving warfarin (P > .05). There was no significant difference in adverse event rate in patients receiving warfarin compared to those receiving aspirin (3.8% vs 9.1%; P = .14), but the rate of hemorrhagic transformation was lower in patients receiving warfarin (1% vs 7%; P = .03). The composite of hemorrhagic stroke or hemorrhagic transformation was significantly lower in patients receiving bridging therapy (0% vs 11%; P = .03). Sixteen patients were readmitted for stroke within 3 months of discharge. Ten were readmitted for ischemic stroke, 3 for hemorrhagic stroke or hemorrhagic transformation, and 3 for systemic bleeding. Ten patients (62.5%) were receiving warfarin at readmission, but only one of these patients had a therapeutic INR. Warfarin was underutilized as secondary stroke prophylaxis in these high-risk patients. Bridging therapy appeared to be safe and was not associated with an increase in adverse events.

Biorefineries produce impure sugar waste streams that are being underutilized. By converting this waste to a profitable by-product, biorefineries could be safeguarded against low oil prices. We demonstrate controlled production of useful carbon materials from the waste concentrate via hydrothermal synthesis and carbonization. We devise a pathway to producing tunable, porous spherical carbon materials by modeling the gross structure formation and developing an understanding of the pore formation mechanism utilizing simple reaction principles. Compared to a simple hydrothermal synthesis from sugar concentrate, emulsion-based synthesis results in hollow spheres with abundant microporosity. In contrast, conventional hydrothermal synthesis produces solid beads with micro and mesoporosity. All the carbonaceous materials show promise in energy storage application. Using our reaction pathway, perfect hollow activated carbon spheres can be produced from waste sugar in liquid effluence of biomass steam pretreatment units. The renewable carbon product demonstrated a desirable surface area of 872 m 2 /g and capacitance of up to 109 F/g when made into an electric double layer supercapacitor. The capacitor exhibited nearly ideal capacitive behavior with 90.5% capacitance retention after 5000 cycles.

Copeland, E. L.; Ray, L. D.; Peticolas, J. D.

1981-01-01

Global geometric shapes such as lines, planes, circles, spheres, cylinders, and the associated computational algorithms which provide relatively inexpensive estimates of minimum spatial clearance for safe operations were selected. The Space Shuttle, remote manipulator system, and the Power Extension Package are used as an example. Robotic mechanisms operate in quarters limited by external structures and the problem of clearance is often of considerable interest. Safe clearance management is simple and suited to real time calculation, whereas contact prediction requires more precision, sophistication, and computational overhead.

An Introduction to Kristof's Theorem for Solving Least-Square Optimization Problems Without Calculus.

PubMed

Waller, Niels

2018-01-01

Kristof's Theorem (Kristof, 1970 ) describes a matrix trace inequality that can be used to solve a wide-class of least-square optimization problems without calculus. Considering its generality, it is surprising that Kristof's Theorem is rarely used in statistics and psychometric applications. The underutilization of this method likely stems, in part, from the mathematical complexity of Kristof's ( 1964 , 1970 ) writings. In this article, I describe the underlying logic of Kristof's Theorem in simple terms by reviewing four key mathematical ideas that are used in the theorem's proof. I then show how Kristof's Theorem can be used to provide novel derivations to two cognate models from statistics and psychometrics. This tutorial includes a glossary of technical terms and an online supplement with R (R Core Team, 2017 ) code to perform the calculations described in the text.

Grape pomace is an abundant source of underutilized winery by-products. Polyphenols were extracted from grape pomace using cellulase and gluco-amylase enzymes. 2,2-diphenyl-1-picrylhydrazyl (DPPH) and Folin-Ciocalteu's assays were used to measure antioxidant activity and total polyphenolic contents. Both cellulase, and gluco-amylase digested grape pomace showed efficient radical scavenging activity. In addition, the total polyphenolic contents of cellulase digested grape pomace showed lower concentrations were effective compared to higher concentrations, whereas gluco-amylase enzyme did not show remarkable variations. The DPPH radical scavenging activity and total polyphenolic contents were significantly higher in the cellulase digested grape pomace compared to the gluco-amylase digested and the not digested grape pomace. It is notable that enzymatic digestions were efficient for extracting polyphenols from grape pomace. The underutilized grape pomace polyphenols can be further used for food safety as a natural antioxidant.

Background We sought to assess injection practices, means of acquiring and disposing of syringes, and utilization and knowledge of harm reduction resources among injection drug users (IDUs) entering methadone maintenance treatment (MMT). Methods Interviews with 100 consecutive patients, including 35 IDUs, entering a MMT program in the Bronx, NY. Results Utilization of unsafe syringe sources was reported by 69% of IDUs in our sample. Most (80%) IDUs reused syringes, and syringe sharing was also common. Fewer than half knew that non-prescription pharmacy purchase of syringes was possible. The most common means of disposing of injecting equipment were the trash (63%) and syringe exchange programs (49%). Conclusions These findings indicate that drug users entering treatment under-utilize sanctioned venues to obtain sterile syringes or safely dispose of used injection equipment. Programs providing services to drug users should adopt a proactive stance to address the safety and health issues faced by injectors. PMID:16503997

2016-03-01

Global nurse migration has a recognized impact on host and source countries, but the lived experience of foreign educated nurses is an important aspect of the success of this migration. A systematic review of the literature was conducted to understand the lived migration and acculturation experiences of foreign educated nurses. A systematic review of the literature, based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, was conducted. Primary research articles or secondary analyses were selected based on keyword and citation-based searches (n = 44). Nurses' experiences included migration and licensing barriers, difficulty with communication, racism and discrimination, skill underutilization, acculturation, and the role of the family. Barriers encountered in host countries may impede acculturation and successful nursing practice, resulting in circular migration and poor patient safety outcomes. Social support systems and cultural orientation programs can mitigate the impacts of social isolation and racism. Addressing common barriers can help minimize deskilling and allow safe and effective transitions to host countries. © The Author(s) 2015.

Low-manpower checkpoints: can they provide effective DUI enforcement in small communities?

Lacey, John H; Ferguson, Susan A; Kelley-Baker, Tara; Rider, Raamses P

2006-09-01

Sobriety checkpoints can be effective in reducing alcohol-impaired driving. Checkpoints are underutilized, however, partially because police believe a large number of officers are required. This study evaluated the feasibility and impact of conducting small-scale checkpoints in rural communities. Law enforcement agencies in two counties agreed to conduct weekly checkpoints for one year. Two nonadjacent counties did not undertake additional checkpoints. Evaluation included public-awareness surveys and roadside surveys (including blood alcohol concentration [BAC] measurements) of weekend nighttime drivers. Relative to drivers in the comparison counties, the proportion of drivers in the experimental counties with BACs >0.05% was 70% lower. Drivers surveyed at driver's license offices in the experimental counties after program implementation were more likely to report seeing or passing through a checkpoint and were more aware of publicity on driving under the influence (DUI) enforcement. Small rural communities can safely and effectively conduct low-staff sobriety checkpoints on a weekly basis. Such programs can be expected to result in large reductions in drivers operating at higher BACs.

Genetic diversity in Carthamus tinctorius (Asteraceae; safflower), an underutilized oilseed crop.

Pearl, Stephanie A; Burke, John M

2014-10-01

• Underutilized crops are potentially valuable resources for meeting increasing food demands. Safflower, an oilseed crop, is an example of one such underutilized crop that thrives in moisture-limited areas. Characterization of the genetic diversity maintained within the gene pools of underutilized crops such as safflower is an important step in their further development.• A total of 190 safflower individuals, including 134 USDA accessions, 48 breeding lines from two private North American safflower breeding companies, and eight wild safflower individuals, were genotyped using 133 single nucleotide polymorphism (SNP) markers. We then used the resulting data to assess the amount and distribution of genetic diversity within and among these collections of safflower.• Although just a modest reduction in gene diversity was observed in the commercial breeding lines (relative to the other safflower groupings), safflower domestication was accompanied by a significant decrease in allelic richness. Further, our results suggest that most safflower breeding lines originated from a single pool of diversity within the Old World safflower germplasm.• Taken together, our results suggest that both the safflower germplasm collection and related, wild species harbor previously undocumented genetic diversity that could help fuel future improvement efforts. Paired with analyses of functional diversity, the molecular resources described herein will be thus be useful in the continued development of safflower as an oilseed crop. © 2014 Botanical Society of America, Inc.

2008-04-01

For more than two decades, Epi Info software has been used to meet the data management, analysis, and mapping needs of public health professionals in more than 181 countries and 13 languages. Until now, most Epi Info systems have been relatively simple, mainly because of a lack of detailed and structured guidance for developing complex systems. We created the structured application framework for Epi Info (SAFE), which is a set of guidelines that allows developers to create both simple and complex information systems using accepted good programming practices. This has resulted in application code blocks that are re-useable and easy to maintain, modify, and enhance. The flexibility of SAFE allows various aggregate and case-based application modules to be rapidly created, combined, and updated to create health information systems or sub-systems enabling continuous, incremental enhancement as national and local capacity increases. SAFE and Epi Info are both cost-free and have low system requirements--characteristics that render this framework and software beneficial for developing countries.

Of bugs and birds: Markov Chain Monte Carlo for hierarchical modeling in wildlife research

USGS Publications Warehouse

Link, W.A.; Cam, E.; Nichols, J.D.; Cooch, E.G.

2002-01-01

Markov chain Monte Carlo (MCMC) is a statistical innovation that allows researchers to fit far more complex models to data than is feasible using conventional methods. Despite its widespread use in a variety of scientific fields, MCMC appears to be underutilized in wildlife applications. This may be due to a misconception that MCMC requires the adoption of a subjective Bayesian analysis, or perhaps simply to its lack of familiarity among wildlife researchers. We introduce the basic ideas of MCMC and software BUGS (Bayesian inference using Gibbs sampling), stressing that a simple and satisfactory intuition for MCMC does not require extraordinary mathematical sophistication. We illustrate the use of MCMC with an analysis of the association between latent factors governing individual heterogeneity in breeding and survival rates of kittiwakes (Rissa tridactyla). We conclude with a discussion of the importance of individual heterogeneity for understanding population dynamics and designing management plans.

Methods for Monte Carlo simulations of biomacromolecules

2010-01-01

The state-of-the-art for Monte Carlo (MC) simulations of biomacromolecules is reviewed. Available methodologies for sampling conformational equilibria and associations of biomacromolecules in the canonical ensemble, given a continuum description of the solvent environment, are reviewed. Detailed sections are provided dealing with the choice of degrees of freedom, the efficiencies of MC algorithms and algorithmic peculiarities, as well as the optimization of simple movesets. The issue of introducing correlations into elementary MC moves, and the applicability of such methods to simulations of biomacromolecules is discussed. A brief discussion of multicanonical methods and an overview of recent simulation work highlighting the potential of MC methods are also provided. It is argued that MC simulations, while underutilized biomacromolecular simulation community, hold promise for simulations of complex systems and phenomena that span multiple length scales, especially when used in conjunction with implicit solvation models or other coarse graining strategies.

Antenatal care (ANC) is an essential intervention to improve maternal and child health. In Nigeria, no population-based studies have investigated predictors of poor receipt of components and uptake of ANC at the national level to inform targeted maternal health initiatives. This study aimed to examine factors associated with inadequate receipt of components and use of ANC in Nigeria. The study used information on 20 405 singleton live-born infants of the mothers from the 2013 Nigeria Demographic and Health Survey. Multivariable logistic regression analyses that adjusted for cluster and survey weights were used to determine potential factors associated with inadequate receipt of components and use of ANC. The prevalence of underutilization and inadequate components of ANC were 47.5% (95% CI: 45.2 to 49.9) and 92.6% (95% CI: 91.8 to 93.2), respectively. Common risk factors for underutilization and inadequate components of ANC in Nigeria included residence in rural areas, no maternal education, maternal unemployment, long distance to health facilities and less maternal exposure to the media. Other risk factors for underutilization of ANC were home births and low household wealth. The study suggests that underutilization and inadequate receipt of the components of ANC were associated with amenable factors in Nigeria. Subsidized maternal services and well-guided health educational messages or financial support from the government will help to improve uptake of ANC services.

Electroconvulsive Therapy Intervention for Parkinson's Disease.

2015-01-01

Electroconvulsive therapy is an established means to improve function in a variety of psychiatric and neurologic conditions, particularly for patients who remain treatment-refractory. Parkinson's disease is a neurodegenerative disorder that sometimes does not respond well to conventional pharmacotherapies. Reports have indicated that electroconvulsive therapy may be an effective and safe treatment for those patients with Parkinson's disease who are not optimally responding to first-line treatments. Despite these reports, however, electroconvulsive therapy is not often used by clinicians in patients with treatment-resistant Parkinson's disease, perhaps due to stigma, lack of knowledge regarding its safety and efficacy, and/or inability to predict the duration of therapeutic benefit. Our objective was to determine if the available literature on ECT supports it as a safe and effective treatment option in patients with treatment-refractory Parkinson's disease. Motoric improvement induced by electroconvulsive therapy has been documented for decades in persons with Parkinson's disease. Efficacy and safety are reported following electroconvulsive therapy in people with Parkinson's disease who have sub-optimal response to medicines or experience the "on/off" phenomenon to L-dopa. Electroconvulsive therapy is an effective option for acute and maintenance treatment of Parkinson's disease in select patients. Inability to predict how long the beneficial effects of ECT therapy will last in patients with Parkinson's disease may be a reason why this treatment is underutilized by clinicians. More research is warranted to clarify parameters for application and duration of therapeutic benefit in individuals with difficult-to-treat Parkinson's disease.

2011-01-01

Low levels of awareness about hereditary breast cancer and ovarian cancer and underutilization of genetic services combined with the high incidence of early onset breast cancer in the black community underscore the urgent need to provide information about hereditary breast and ovarian cancer to black women. The primary goal of the present study was to develop a culturally targeted brochure designed to increase awareness about inherited breast cancer among black women using the principles of Learner Verification. Three focus groups were conducted with black women, including those with or without a history of breast cancer (n = 46), to evaluate the brochure. Data were analyzed through hand coding using a simple classification system placing participants' responses in the predetermined Learner Verification categories. On the basis of the feedback obtained, the brochure has been modified to improve cultural-targeting, relevance, and clarity and has been made available for dissemination. Our study illustrates the importance of obtaining feedback from the target audience when developing a culturally targeted informational brochure for black women. Further, the complexity of our subject matter (i.e., inherited breast and ovarian cancer) underscores the importance of using inviting visuals and personal vignettes, while maintaining a simple and clear message.

Bowland, Christopher C.; Nguyen, Ngoc A.; Naskar, Amit K.

2018-03-01

With current carbon composites being introduced into new commercial market sectors, there is an opportunity to develop multifunctional composites, which are poised to be the next generation of composites that will see future commercial applications. This multifunctional attribute can be achieved via integrated nanomaterials, which are currently under-utilized in real-world applications despite significant research efforts focused on their synthesis. This research utilizes a simple, scalable approach to integrate various nanomaterials into carbon fiber composites by embedding the nanomaterials in the epoxy fiber sizing. Illustrated in this work is the effect of silicon carbide nanoparticle concentrations and dimensions on the structural health monitoring sensitivity of unidirectional carbon fiber composites. Additionally, the nanoparticles contribute to the overall damping property of the composites thus enabling tunable damping through simple variations in nanoparticle concentration and size. Not only does this nanoparticle sizing offer enhanced sensitivity and tunable damping, but it also maintains the mechanical integrity and performance of the composites, which demonstrates a truly multifunctional composite. Therefore, this research establishes an efficient route for combining nanomaterials research with real-world multifunctional composite applications using a technique that is easily scalable to the commercial level and is compatible with a wide range of fibers and nanomaterials.

The levonorgestrel-releasing intrauterine system: Safety, efficacy, and patient acceptability

Beatty, Megan N; Blumenthal, Paul D

2009-01-01

The levonorgestrel-releasing intrauterine system (LNG-IUS) is a safe, effective and acceptable form of contraception used by over 150 million women worldwide. It also has a variety of noncontraceptive benefits including treatment for menorrhagia, endometriosis, and endometrial hyperplasia. The LNG-IUS has also been used in combination with estrogen for hormone replacement therapy and as an alternative to hysterectomy. Overall, the system is very well tolerated and patient satisfaction is quite high when proper education regarding possible side effects is provided. However, despite all of the obvious benefits of the LNG-IUS, utilization rates remain quite low in the developed countries, especially in the United States. This is thought to be largely secondary to the persistent negative impressions from the Dalkon Shield intrauterine experience in the 1970s. This history continues to negatively influence the opinions of both patients and health care providers with regards to intrauterine devices. Providers should resolve to educate themselves and their patients on the current indications and uses for this device, as it, and intrauterine contraception in general, remains a largely underutilized approach to a variety of women’s health issues.

Lamin, Eliza; Parrillo, Lisa M; Newman, Diane K; Smith, Ariana L

2016-02-01

Pelvic floor disorders are highly prevalent in women of all ages and can greatly impair quality of life. Pelvic floor muscle training (PFMT) is a viable treatment option for several pelvic floor conditions including urinary incontinence and pelvic organ prolapse. PFMT is a program of therapy initiated by an experienced clinician (e.g., women's health or urology nurse practitioner (NP), physical therapist (PT)) that involves exercises for women with stress urinary incontinence (UI) and exercises combined with behavioral or conservative treatments (lifestyle changes, bladder training with urge suppression) for women with urgency or mixed UI. These exercise programs are more comprehensive than simple Kegel exercises. Despite evidence-based research indicating the efficacy and cost-effectiveness for treatment of urinary incontinence, PFMT is not commonly used as a first-line treatment in clinical practice in the USA (Abrams et al., 2012). This article will review PFMT for the treatment of UI and pelvic organ prolapse (POP) and theorize how this conservative therapy can be utilized more effectively in the USA.

A wealth of genomic information is available in public and private databases. However, this information is underutilized for uncovering population specific and functionally relevant markers underlying complex human traits. Given the huge amount of SNP data available from the annotation of human genetic variation, data mining is a faster and cost effective approach for investigating the number of SNPs that are informative for ancestry. In this study, we present AncestrySNPminer, the first web-based bioinformatics tool specifically designed to retrieve Ancestry Informative Markers (AIMs) from genomic data sets and link these informative markers to genes and ontological annotation classes. The tool includes an automated and simple “scripting at the click of a button” functionality that enables researchers to perform various population genomics statistical analyses methods with user friendly querying and filtering of data sets across various populations through a single web interface. AncestrySNPminer can be freely accessed at https://research.cchmc.org/mershalab/AncestrySNPminer/login.php. PMID:22584067

The use of 3D information has shown impact in numerous applications in drug design. However, it is often under-utilized and traditionally limited to specialists. We want to change that, and present an approach making 3D information and molecular modeling accessible and easy-to-use 'for the people'. A user-friendly and collaborative web-based platform (3D-Lab) for 3D modeling, including a blazingly fast virtual screening capability, was developed. 3D-Lab provides an interface to automatic molecular modeling, like conformer generation, ligand alignments, molecular dockings and simple quantum chemistry protocols. 3D-Lab is designed to be modular, and to facilitate sharing of 3D-information to promote interactions between drug designers. Recent enhancements to our open-source virtual reality tool Molecular Rift are described. The integrated drug-design platform allows drug designers to instantaneously access 3D information and readily apply advanced and automated 3D molecular modeling tasks, with the aim to improve decision-making in drug design projects.

Visual function demands coordinated responses to information over a wide field of view, involving both central and peripheral vision. Visually impaired individuals often seem to underutilize peripheral vision, even in absence of obvious peripheral deficits. Motivated by perceptual training studies with typically sighted adults, we examined the effectiveness of perceptual training in improving peripheral perception of visually impaired youth. Here, we evaluated the effectiveness of three training regimens: (1) an action video game, (2) a psychophysical task that combined attentional tracking with a spatially and temporally unpredictable motion discrimination task, and (3) a control video game. Training with both the action video game and modified attentional tracking yielded improvements in visual performance. Training effects were generally larger in the far periphery and appear to be stable 12 months after training. These results indicate that peripheral perception might be under-utilized by visually impaired youth and that this underutilization can be improved with only ~8 hours of perceptual training. Moreover, the similarity of improvements following attentional tracking and action video-game training suggest that well-documented effects of action video-game training might be due to the sustained deployment of attention to multiple dynamic targets while concurrently requiring rapid attending and perception of unpredictable events.

Airport surveys at travel destinations--underutilized opportunities in travel medicine research?

PubMed

Bauer, Irmgard L

2015-01-01

Research in destination airports, especially in resource-poor areas, allows unique immediate access to travelers at the conclusion of their trip. Response rates are high and the recall gap small. Trip-related health matters can be elicited relatively easily. An insight into travelers' decision-making processes on location would fill large gaps in our knowledge regarding travel health advice provision; yet, this approach is still much underutilized. Using PubMed, ScienceDirect, Google Scholar, and ProQuest, a review of the literature on airport surveys was conducted to determine where they were used, their response rates and purpose, and location-relevant methodological information. The lack of methodological guidelines in the reviewed literature resulted in recommendations for planning and conducting an airport survey at a destination airport. Millions of travelers in airports around the world represent an underutilized sample of potential study participants for topics that cannot be studied adequately in other settings. Benefiting from close cooperation between travel health professionals and airport authorities, researchers can expect not only large-scale convenience samples for surveys, but also opportunities to explore exciting and creative research topics to broaden our understanding of travel medicine and health. © 2014 International Society of Travel Medicine.

Laparoscopic correction of perforated peptic ulcer (PPU) has become an accepted way of management. Patch omentoplasty stayed for decades the main method of repair. The goal of the present study was to evaluate whether laparoscopic simple repair of PPU is as safe as patch omentoplasty. Since June 2005, 179 consecutive patients of PPU were treated by laparoscopic repair at our centers. We conducted a retrospective chart review in December 2012. Group I (patch group) included patients who were treated with standard patch omentoplasty. Group II (non-patch group) included patients who received simple repair without patch. From June 2007 to Dec. 2012, 179 consecutive patients of PPU who were treated by laparoscopic repair at our centers were enrolled in this multi-center retrospective study. 108 patients belong to patch group. While 71 patients were treated with laparoscopic simple repair. Operative time was significantly shorter in group II (non patch) (p = 0.01). No patient was converted to laparotomy. There was no difference in age, gender, ASA score, surgical risk (Boey's) score, and incidence of co-morbidities. Both groups were comparable in terms of hospital stay, time to resume oral intake, postoperative complications and surgical outcomes. Laparoscopic simple repair of PPU is a safe procedure compared with the traditional patch omentoplasty in presence of certain selection criteria. Copyright © 2013 Surgical Associates Ltd.

Currently, the genetic variants identified by genome wide association study (GWAS) generally only account for a small proportion of the total heritability for complex disease. One crucial reason is the underutilization of gene-gene joint effects commonly encountered in GWAS, which includes their main effects and co-association. However, gene-gene co-association is often customarily put into the framework of gene-gene interaction vaguely. From the causal graph perspective, we elucidate in detail the concept and rationality of gene-gene co-association as well as its relationship with traditional gene-gene interaction, and propose two Fisher r-to-z transformation-based simple statistics to detect it. Three series of simulations further highlight that gene-gene co-association refers to the extent to which the joint effects of two genes differs from the main effects, not only due to the traditional interaction under the nearly independent condition but the correlation between two genes. The proposed statistics are more powerful than logistic regression under various situations, cannot be affected by linkage disequilibrium and can have acceptable false positive rate as long as strictly following the reasonable GWAS data analysis roadmap. Furthermore, an application to gene pathway analysis associated with leprosy confirms in practice that our proposed gene-gene co-association concepts as well as the correspondingly proposed statistics are strongly in line with reality.

With the increase in number of patients treated for urological problems with endoscopic procedures, the number of patients with JJ stent is also increasing. The amount of workload thus incurred multiplies, even to the point that, sometimes we waste more time in the operating room removing JJ stents than the actual endourological procedures. Here in our institute, we have devised a very simple and effective way of removing JJ stents in women and also determined the efficacy, safety and cost of JJ stent removal under ultrasound guidance in women in comparison to cystoscopic removal. Two hundred women attending the Department of Urology from July 2012 to July 2013 at RIMS hospital were randomly divided into two arms. One hundred women had their JJ stent removed with cystoscope and another 100 women had their JJ stent removed under ultrasound guidance using simple surgical tools available at the hospital. The primary comparative points were waiting time for operating room appointment date, cost of the procedure, time taken for the procedure, discomfort or pain felt by the patient and urethral injuries. In all the parameters, stent removal under ultrasound guidance was significantly better except for urethral injuries where both the procedures had similar outcomes. We concluded that JJ stent removal under ultrasound guidance in women was simple, effective and safe.

Modern GPUs employ cache to improve memory system efficiency. However, large amount of cache space is underutilized due to irregular memory accesses and poor spatial locality which exhibited commonly in GPU applications. Our experiments show that using smaller cache lines could improve cache space utilization, but it also frequently suffers from significant performance loss by introducing large amount of extra cache requests. In this work, we propose a novel cache design named tag-split cache (TSC) that enables fine-grained cache storage to address the problem of cache space underutilization while keeping memory request number unchanged. TSC divides tag into two partsmore » to reduce storage overhead, and it supports multiple cache line replacement in one cycle.« less

Acute migraine: Current treatment and emerging therapies

Migraine is a common disabling primary headache disorder. Despite the need for a perfect treatment of this debilitating condition, the ideal “cure” eludes us. In 1992, the first triptan was released in the US for use in acute migraine. Triptans are more specific for the serotonin receptor 5-hydroxy triptamine (5-HT) 1 than previously prescribed drugs, such as ergotamines, with fewer side effects. This was an important first step in specific acute migraine therapy. Today however, triptans continue to be underutilized. There remains a concern, among practitioners and patients, about possible cardiovascular safety issues, despite the lack of strong evidence of serious adverse events. In fact, triptans now have a safe track record over more than a decade of use. Other perceived downfalls to use, include cost and variable efficacy. The more we learn about the clinical features and pathophysiology of migraine, the closer we are to finding a satisfactory monotherapy. Until then, recognizing that mixed mechanisms underlie migraine symptoms, rational polytherapy can be useful. Research on the roles of serotonin, calcitonin gene related peptide, glutamine and N-methyl-D-aspartate in the trigeminovascular system holds promise for those searching for the perfect migraine headache cure.

2012-01-01

To explore the use of ultrasonography as a diagnostic alternative to the traditional "gold standard" imaging study of nuclear scintigraphy in the evaluation of thyrotoxicosis. We review the relevant literature and share our own experience to highlight the promising role of ultrasonography in thyrotoxicosis. In addition, we present a diagnostic algorithm suggesting liberal use of ultrasonography in the evaluation of thyrotoxicosis. Ultrasonography has proved effective not only in the differentiation of Graves disease from other types and causes of thyrotoxicosis but also in the detection of subtle thyroid nodules. The latter role is emphasized in light of the recent observation of an increased risk of occurrence of papillary thyroid carcinoma in patients with Graves disease. Ultrasonography is a cost-effective, noninvasive, portable, and safe imaging modality in the evaluation of thyrotoxicosis, both for physiologic assessment and for detection of nonpalpable thyroid cancers that may elude identification on physical examination and nuclear imaging studies. Although thyroid scintigraphy remains a standard radiologic study, thyroid ultrasonography can be a practical alternative in many cases and the primary imaging modality in some situations such as during pregnancy and lactation and for evaluation and management of amiodarone-induced thyrotoxicosis.

Early initiation of beta blockade in heart failure: issues and evidence.

Williams, Randall E

2005-09-01

Despite clinical trials demonstrating that inhibitors of the renin-angiotensin and sympathetic nervous systems can reduce the mortality and morbidity risk associated with heart failure, these drugs have remained underutilized in general clinical practice. In particular, many patients with heart failure due to left ventricular systolic dysfunction fail to receive beta blockers, although this class of drugs, as well as other antihypertensive agents such as angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, are recommended as part of routine heart failure therapy by national expert consensus guidelines. In-hospital initiation of beta-blocker therapy may improve long-term utilization by physicians and compliance by patients through obviating many of the misperceived dangers associated with beta blockade. The following review of the clinical trial data from the Randomized Evaluation of Strategies for Left Ventricular Dysfunction (RESOLVD) trial, the Metoprolol Controlled-Release Randomized Intervention Trial in Heart Failure (MERIT-HF), the Cardiac Insufficiency Bisoprolol Study II (CIBIS-II), the Carvedilol Prospective Randomized Cumulative Survival (COPERNICUS) trial, and the Initiation Management Predischarge Process for Assessment of Carvedilol Therapy for Heart Failure (IMPACT-HF) trial on the efficacy, safety, and tolerability of beta blockers indicates that early initiation can be safely achieved and can improve patient outcomes.

Maintaining a standard of excellence for graduating surgical residents requires a comprehensive and consistent approach to surgical education. The omnipresent and increasing barriers to education must also be recognized and addressed. The implementation of effective teaching strategies is largely dependent on the resources available at each institution and the vision of education. Unfortunately, allocating time for surgeons to teach both inside and outside the operating room has become a foreign concept to administration. Furthermore, the reduction in case numbers performed by trainees now demands "quality over quantity" to ensure success. Quality teaching moments will only be realized when emphasis is placed on preparation, useful instruction during the procedure, and postoperative feedback. Ideal preparation entails a detailed discussion between the trainee and surgeon about the specific learning goals for the case. During the procedure, the faculty surgeon must strive to maximize the experience through effective communication while performing an efficient and safe operation. Numerous validated objective assessment tools exist for postprocedure evaluation but are grossly underutilized. Surgical education must thoughtfully be approached with the same fervor and detail as patient care. As faculty, it is our responsibility to train the next generation of surgeons and therefore "every case must count."

Airports throughout the United States are plagued with growing congestion. With the increase in air traffic predicted in the next few years, congestion will worsen. The accepted solution of building larger airplanes to carry more travelers is no longer a viable option, as airports are unable to accommodate larger aircraft without expensive infrastructure changes. Past NASA research has pointed to the need for a new approach, which can economically and safely utilize smaller airports. To study this option further, NASA requested the California Polytechnic State University at San Luis Obispo (Cal Poly/SLO) to design a baseline aircraft to be used for system studies. The requirements put forth by NASA are summarized. The design team was requested to create a demonstrator vehicle, which could be built without requiring enabling technology development. To this end, NASA requested that the tested and proven high-lift system of the Boeing C-17 Globemaster III be combined with the fuselage of the BAe-146. NASA also requested that Cal Poly determine the availability and usability of underutilized airports starting with California, then expanding if time and funds permitted to the U.S.

The present study aimed to determine the antioxidant activity and phytochemical contents in 10 underutilized fruits of Andaman Islands (India) namely Malpighia glabra L., Mangifera andamanica L., Morinda citrifolia L., Syzygium aqueum (Burm.f) Alst., Annona squamosa L., Averrhoa carambola L., Averrhoa bilimbi L., Dillenia indica L., Annona muricata L. and Ficus racemosa L. The antioxidant activity varied from 74.27% to 98.77%, and the methanol extract of M. glabra showed the highest antioxidant activity (98.77%; inhibitory concentration, IC(50) = 262.46 μg/ml). Methanol was found to be a better solvent than acetone and aqueous for estimating the antioxidant activity. M. glabra was found to be rich in phytochemicals viz. polyphenol (355.74 mg/100 g), anthocyanin (91.31 mg/100 g), carotenoids (109.16 mg/100 g), tannin (24.39 mg/100 g) and ascorbic acid (394.23 mg/100 g). Carbohydrate content was estimated to be highest in M. glabra (548 mg/100 g). Phenols, tannins, anthocyanins and carotenoids contents showed positive correlation (r² = 0.846, r² = 0.864, r² = 0.915 and r² = 0.806, respectively) with antioxidant activity. The information generated in present study will be useful for bioprospecting of underutilized fruits of Andaman Islands.

Low health literacy and healthcare utilization among immigrants and non-immigrants in Switzerland.

This study aimed at investigating the association between functional health literacy and knowledge on when to seek medical help for potentially harmless (overutilization) or serious (underutilization) situations among immigrants and non-immigrants in Switzerland. Data was collected among three immigrant groups and the native population (N=1146) in the German- and Italian-speaking part of Switzerland. Health literacy was assessed with the Short Test of Functional Health Literacy (S-TOFHLA) and three Brief Health Literacy Screeners. Over- and underutilization of healthcare services was assessed with items asking participants about when to seek medical help for minor, respectively major, physical symptoms. Immigrants were more likely to seek medical help when unwarranted (overutilization). Health literacy, when assessed with the S-TOFHLA, was significantly associated with over- and underutilization. Yet, once controlled for covariates, the association between health literacy and overutilization was negative. Immigration background and micro-cultural differences emerged as important predictors of utilization. Results suggest that functional health literacy is directly related to healthcare utilization. The effects might be amplified by (micro-)cultural differences. Healthcare providers should be aware of differences in health literacy and utilization patterns among different population groups. Communication between patients and providers should be literacy and culturally sensitive. Copyright © 2017 Elsevier B.V. All rights reserved.

Condensed tannin (CT) or proanthocyanidin (PA) is a unique group of phenolic metabolite with high molecular weight with specific structure. It is reported that, the presence of high-CT in the legumes adversely affect the nutrients in the plant and impairs the digestibility upon consumption by animals. Winged bean (Psophocarpus tetragonolobus (L.) DC.) is one of the promising underutilized legume with high protein and oil-content. One of the reasons for its underutilization is due to the presence of CT. Transcriptome sequencing of leaves of two diverse CT-containing lines of P. tetragonolobus was carried out on Illumina Nextseq 500 sequencer to identify the underlying genes and contigs responsible for CT-biosynthesis. RNA-Seq data generated 102586 and 88433 contigs for high (HCTW) and low CT (LCTW) lines of P. tetragonolobus, respectively. Based on the similarity searches against gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) database revealed 5210 contigs involved in 229 different pathways. A total of 1235 contigs were detected to differentially express between HCTW and LCTW lines. This study along with its findings will be helpful in providing information for functional and comparative genomic analysis of condensed tannin biosynthesis in this plant in specific and legumes in general.

Many of the plant species that are cultivated for food across the world are neglected and underutilized. To assess their diversity in Benin and identify the priority species and establish their research needs, a survey was conducted in 50 villages distributed throughout the country. The study revealed 41 neglected and underutilized crop species (NUCS) among which 19 were identified as of priority base on 10 criteria among which included their extent and degree of consumption. Reasons for neglect vary with the producers and the agricultural technicians. Market surveys revealed that NUCS are important source of household incomes and substantially contribute to poverty reduction. Review of the literature available revealed that most of the species are rich in nutrients and have some proven medicinal values and the promotion of their use would help in combating malnutrition and improving the health status of the local populations. The knowledge gaps and research needs are immense on most of the species identified as no concrete scientific data is nationally available. In terms of research, almost all has to be done starting from basic ethnobotanical investigation. The results will help the scientists and students willing to conduct research on NUCS in Benin to better orient their research programs. PMID:22593712

Timor-Leste is a young country in the Asia-Pacific region with a high maternal mortality rate of 557 per 100,000 live births. As most maternal deaths can be prevented by providing quality antenatal care (ANC) and skilled assistance during childbirth, understanding the barriers to the utilization of ANC services can enhance program implementation. This study aimed to investigate the prevalence and factors associated with the under-utilization of ANC services in Timor-Leste. Timor-Leste Demographic and Health Survey (TDHS) 2009-2010 was a nationally representative multi-stage cross-sectional study involving 11,463 households and 9,828 childbirths. Information on last born child was recorded for 5,895 mother-child pairs. Factors influencing under-utilization of ANC were assessed using hierarchical logistic regression analysis. Only 3311 (55.2, 95% confidence interval (CI) 53.1 to 57.3%) made the recommended four ANC visits, while 2584 (44.8; 95% CI 42.7 to 46.9%) of them reported attending three or less ANC services. Significant factors positively associated with the under-utilization of ANC were low wealth status (odds ratio (OR) 2.09; 95% CI 1.68 to 2.60), no maternal education (OR 1.54; 95% CI 1.30 to 1.82) or primary maternal education (OR 1.21; 95% CI 1.04 to 1.41), no paternal education (OR 1.34; 95% CI 1.13 to 1.60), and having a big problem in permission to visit health facility (OR 1.65; 95% CI 1.39 to 1.96). Despite the apparently good progress made in re-establishing the healthcare infrastructure, 45 % of mothers remained in need of a focused intervention to increase their use of ANC services. Further prenatal care program should pay attention to women with low wealth status and those and their partners who are uneducated. Moreover, women should be encouraged to make decision on their own health.

The use of water as the solvent for the functionalization ensures that solvent induced swelling does not affect the optical or mechanical properties of the polycarbonate.

We analyzed the records of 77 cases of loop colostomy closure in Vietnam War Casualties. All records were complete from the date of injury to discharge following colostomy closure. Simple of the loop colostomy was performed in 44 patients and resection of the stoma and reanastomosis of bowel segments was performed in 33 patients. Average operating time for simple closure of the loop was 70 minutes compared to 115 minutes for resection and anastomosis. Nasogastric suction was used less frequently and for a shorter time with simple loop closure. The total postoperative complication rate was 9% with simple loop closure as compared to 24% for resection and anastomosis. Simple closure of the loop described in this report is technically easier and as safe as resection of the stoma and reanastomosis. Images Fig. 1. PMID:1094967

Carotid revascularization is performed to prevent stroke. Carotid tandem lesions represent a challenge for treatment, and a hybrid approach may result effective. A high-risk 65-year-old woman presented with a "tandem lesion" of left common and internal carotid artery. She was deemed unfit for "simple" standard carotid endarterectomy (CEA). A "single-step" safe hybrid procedure was scheduled for the patient. A "Cormier" carotid vein graft bypass with a retrograde stenting was performed under local anesthesia. The "safe hybrid procedure" for tandem lesions of the common and internal carotid artery is effective and suitable in high-risk patients in a high-volume centers. Copyright © 2016 Elsevier Inc.

Exercise is an inconsistently managed area in the health of expectant mothers. It is an area where family doctors have an opportunity to be well informed and willing to give advice. To provide simple advice on safe exercise practice in pregnancy. Exercise in pregnancy has multiple benefits for the mother, including reduced risk of mental health problems, diabetes and hypertension, and faster recovery after delivery. There are no proven risks to the fetus if practiced safely. Understanding the physiological changes of pregnancy and the possible complications of high-intensity or contact sport is important but in general, moderate levels of exercise 3-4 times per week is safe for both mother and baby in low-risk pregnancies.

With today’s National Health Service (NHS) facing huge financial pressures the healthcare profession cannot afford to carry on spending at the current rate. Individual clinicians should be encouraged to critically appraise their own practices to bring about a more efficient and cost-effective service. The purpose of this project was to analyse the way that carpal tunnel surgery was being performed within our institution and bring about safe changes to practice that reduce expenditure. By critiquing our practices and applying simple changes based around sound evidence an annual saving of over £15 500 to the department was made. The changes instigated are simple, sustainable and safe to implement while providing improved patient satisfaction. They are also easily transferrable across institutions and to other minor hand surgical procedures to afford even greater ongoing savings to the NHS. PMID:29946571

Although the goals of end-of-life care and hospice are to mitigate suffering and improve quality of life for patients with terminal illnesses, they remain underutilized by a significant number of African Americans. While sociocultural issues play a role in the underutilization of these resources among African Americans, other confounding factors affect the ability of African Americans to adequately access quality care at the end of life. Here, the authors examine the various barriers preventing increased use of hospice care and palliative therapy among African Americans. A particular focus of this examination will revolve around suggestions for increasing the use of end-of-life care among African Americans in the future.

Safehold Attitude Determination Approach for GPM

NASA Technical Reports Server (NTRS)

Fitzpatrick, Henry; DeWeese, Keith

2012-01-01

Spacecraft sating designs generally have minimal goals with loose pointing requirements. Safe pointing orientations for three-axis stabilized spacecraft are usually chosen to put the spacecraft into a thermally safe and power-positive orientation. In addition, safe mode designs are required to be simple and reliable. This simplicity lends itself to the usage of analog sun sensors, because digital sun sensors will add unwanted complexity to the safe hold mode. The Global Precipitation Measurement (GPM) Mission Core Observatory will launch into lower earth orbit (LEO) at an inclination of 65 degrees. The GPM instrument suite consists of an active radar system and a passive microwave imager to provide the next-generation global observations of rain and snow. The complexity and precision of these instruments along with the operational constraints of the mission result in tight pointing requirements during all phases of the mission. To ensure the instruments are not damaged during spacecraft safing, thermal constraints dictate that the solar pointing orientation must be maintained to better than 6.5 degrees. This requirement is outside the capabilities of a typical analog sun sensor suite, primarily due to the effects of Earth's albedo. To ensure mission success, a new analog sensor, along with the appropriate algorithms, is needed. This paper discusses the design issues involving albedo effects on spacecraft pointing and the development of a simple, low-cost analog sensor and algorithm that will address the needs of the GPM mission. In addition, the algorithms are designed to be easily integrated into the existing attitude determination software by using common interfaces. The sensor design is based on a heritage, commercial off-the-shelf analog sun sensors with a limited field-of-view to reduce the effects of Earth's albedo. High fidelity simulation results are presented that demonstrate the efficacy of the design.

Achieving a formed and firm eyeball which is stably fixed in a holding device is a major challenge of surgical wet-lab training. Our innovation, the 'Spring-action Apparatus for Fixation of Eyeball (SAFE)' is a robust, simple and economical device to solve this problem. It consists of a hollow iron cylinder to which a spring-action syringe is attached. The spring-action syringe generates vacuum and enables reliable fixation of a human or animal cadaveric eye on the iron cylinder. The rise in intraocular pressure due to vacuum fixation can be varied as per need or nature of surgery being practised. A mask-fixed version of this device is also designed to train surgeons for appropriate hand positioning. An experienced surgeon performed various surgeries including manual small incision cataract surgery (MSICS), phacoemulsification, laser in situ keratomileusis (LASIK), femtosecond LASIK docking, Descemet's stripping endothelial keratoplasty, deep anterior lamellar keratoplasty, penetrating keratoplasty and trabeculectomy on this device, while a trainee surgeon practised MSICS and wound suturing. Skill-appropriate comfort level was much higher with SAFE than with conventional globe holders for both surgeons. Due to its stability, pressure adjustability, portability, cost-efficiency and simplicity, we recommend SAFE as the basic equipment for every wet lab. Published by the BMJ Publishing Group Limited.

The SAFE-I00a test article at the NASA Marshall Space Flight Center was used to simulate a variety of potential reactor transients; the SAFEl00a is a resistively heated, stainless-steel heat-pipe (HP)-reactor core segment, coupled to a gas-flow heat exchanger (HX). For these transients the core power was controlled by a point kinetics model with reactivity feedback based on core average temperature; the neutron generation time and the temperature feedback coefficient are provided as model inputs. This type of non-nuclear test is expected to provide reasonable approximation of reactor transient behavior because reactivity feedback is very simple in a compact fast reactor (simple, negative, and relatively monotonic temperature feedback, caused mostly by thermal expansion) and calculations show there are no significant reactivity effects associated with fluid in the HP (the worth of the entire inventory of Na in the core is .

Help-Seeking Intentions among Asian American and White American Students in Psychological Distress: Application of the Health Belief Model

2015-01-01

Objective Underutilization of needed mental health services continues to be the major mental health disparity affecting Asian Americans (Sue, Cheng, Saad, & Chu, 2012). The goal of the study was to apply a social psychological theoretical framework—the Health Belief Model (Rosenstock, 1966)—to understand potential reasons why Asian Americans underutilize mental health services relative to White Americans. Method Using a cross-sectional online questionnaire, this study examined how perceived severity of symptoms, perceived susceptibility to mental health problems, perceived benefits of treatment, and perceived barriers to treatment influenced intentions to seek help among a sample of 395 Asian American and 261 White American students experiencing elevated levels of psychological distress. Results Analyses using structural equation modeling indicated that Asian Americans in distress had relatively lower intentions to seek help compared to White Americans. Perceived benefits partially accounted for differences in help-seeking intentions. Although Asian Americans perceived greater barriers to help-seeking than White Americans, it did not significantly explain racial/ethnic differences in help-seeking intentions. Perceived severity and barriers were related to help-seeking intentions in both groups. Conclusions Outreach efforts that particularly emphasize the benefits of seeking mental health services may be a particularly promising approach to address underutilization. These findings have implications in help-seeking promotion and outreach. PMID:26098454

Chan, Lauryn G; Cohen, Joshua L; de Moura Bell, Juliana Maria Leite Nobrega

2018-03-25

The design of new food products and increased agricultural activities have produced a diversity of waste streams or by-products that contain a high load of organic matter. The underutilization of these streams presents a serious threat to the environment and to the financial viability of the agricultural sector and the food industry. Oleaginous microorganisms, such as yeast and microalgae, have been used to convert the organic matter present in many agricultural waste streams into an oil-rich biomass. Filamentous fungi are promising oleaginous microorganisms because of their high lipid accumulation potential and simple biomass recovery, the latter being related to their pellet-like growth morphology in submerged cultivation. This review highlights the use of oleaginous filamentous fungi to convert food by-products into value-added components, including the effect of cultivation conditions on biomass yield and composition. Special attention is given to downstream processing for the commercial production of fungal oil. Also discussed are innovative techniques to optimize the biomass oil yield and to minimize the challenges associated with biomass harvesting and oil extraction at industrial scale.

Low-cost Volumetric Ultrasound by Augmentation of 2D Systems: Design and Prototype.

Herickhoff, Carl D; Morgan, Matthew R; Broder, Joshua S; Dahl, Jeremy J

2018-01-01

Conventional two-dimensional (2D) ultrasound imaging is a powerful diagnostic tool in the hands of an experienced user, yet 2D ultrasound remains clinically underutilized and inherently incomplete, with output being very operator dependent. Volumetric ultrasound systems can more fully capture a three-dimensional (3D) region of interest, but current 3D systems require specialized transducers, are prohibitively expensive for many clinical departments, and do not register image orientation with respect to the patient; these systems are designed to provide improved workflow rather than operator independence. This work investigates whether it is possible to add volumetric 3D imaging capability to existing 2D ultrasound systems at minimal cost, providing a practical means of reducing operator dependence in ultrasound. In this paper, we present a low-cost method to make 2D ultrasound systems capable of quality volumetric image acquisition: we present the general system design and image acquisition method, including the use of a probe-mounted orientation sensor, a simple probe fixture prototype, and an offline volume reconstruction technique. We demonstrate initial results of the method, implemented using a Verasonics Vantage research scanner.

Seizure drawings: insight into the self-image of children with epilepsy.

Epilepsy is a chronic disorder that is associated with numerous psychological challenges, especially in children. Drawings have been underutilized as a method to obtain insight into psychological issues in children with epilepsy. We asked 105 children with epilepsy, ages 5 to 18 years, to draw a picture of what it is like to have a seizure. Across ages and epilepsy syndromes, the drawings showed evidence of impaired self-concept, low self-esteem, and a sense of helplessness and vulnerability. Overall, the drawings of human figures were less developed than expected for chronological age. In some drawings, indicators of underlying depression were found. When considered by epilepsy syndrome or seizure type, some specific artistic features were noted. Children with simple partial (motor) seizures drew distorted body parts, especially limbs. Those with complex partial seizures depicted sensory symptoms and mental status changes such as confusion. Children with generalized tonic-clonic seizures showed shaking extremities. Drawings by children with absence seizures illustrated mainly staring. In conclusion, drawings are a powerful method to examine the self-concept of children with epilepsy and gain insight into their feelings about themselves and their world.

Usability Considerations in Developing a Graphic Interface for Intra Office Communications

NASA Astrophysics Data System (ADS)

Yammiyavar, Pradeep; Jain, Piyush

This paper outlines the basis of incorporating functional features in a new GUI based software under development for addressing comprehensive communication and interaction needs within an office environment. Bench marking of features in existing communication software products such as Microsoft Outlook, IBM Lotusnotes, Office Communicator, Mozilla Thunderbird etc. was done by asking a set of questions related to the usage of these existing softwares. Usability issues were identified through a user survey involving 30 subjects of varied profiles (domain, designation, age etc.) in a corporate office. It is posited that existing software products that have been developed for a universal market may be highly underutilized or have redundant features especially for use as an intra office (within the same office) communication medium. Simultaneously they may not cater to some very contextual requirements of intra office communications. Based on the findings of the survey of feature preferences & usability of existing products, a simple 'person to person' communicating medium for intra office situations was visualized with a new interactive GUI. Usability issues that need to be considered for a new intra-office product have been brought out.

[Evaluation of the efficacy of diode laser endocyclophotocoagulation combined with cataract surgery in glaucoma].

PubMed

Ezzouhairi, S M

2015-11-01

Surgical techniques, which reduce the secretion of aqueous humor are underutilized in the surgical management of glaucoma; the diode laser coupled to an endoscope, endocyclophotocoagulation (ECP), is an emerging technology in the treatment of glaucoma. Indeed, thanks to its direct, focal and controllable approach to diode laser treatment of the ciliary processes, ECP renders this a safer technique compared to transscleral diode laser. We present preliminary results and an evaluation of the efficacy of ECP combined with cataract surgery performed at the Al Bassar clinic in Mohammedia, Morocco. We conducted a retrospective study on a series of 82 patients who underwent combined surgery: diode laser endocyclophotocoagulation and cataract for treatment of glaucoma during the period from December 2012 to July 2013. For this study, we recorded: age and gender of the patients, number and power of diode laser spots, pre- and postoperative intraocular pressure (IOP), and the number of anti-glaucoma treatments prescribed pre- and postoperatively (3 months minimum). Technically, a 20-gauge endo-ocular probe is inserted through the corneal incision used for phacoemulsification. The probe is equipped with a light source, a camera and a pulsed 810 nm laser beam; it is connected to an Endo-optiks type generator, which allows for direct visualization of the ciliary processes and their precise treatment. The surgical procedure is both simple and quick. Postoperative follow-up is unchanged from the management of cataract extraction by phacoemulsification. The average age in our series was 69.5 years (range 33-81 years), mean follow-up was 5.7 months. The reduction in intraocular pressure was 28.5%. In 40% of patients, a significant reduction in medications was noted, and in 20%, a total suspension of anti-glaucoma medications. No serious complications were noted in our series. This technique can perfectly fit into the medical, natural and/or surgical armamentarium medical, physical, surgical to halt progression of glaucomatous disease. The IOP lowering obtained by this combined surgery is significantly greater than that obtained after phacoemulsification alone in open-angle glaucoma. It can accommodate many situations for which conventional surgery has limitations. In addition, this technique has the advantage of preserving the bulbar conjunctiva for any subsequent glaucoma surgeries. Our preliminary results are very satisfactory. This combined technique is simple, safe and effective. This allows broadening of its indications to include moderate glaucoma, stabilized or not, in addition to refractory glaucoma. Also, from an economic point of view, the gain for the patient is significant. Of course, longer-term follow-up is required to confirm these results. Copyright © 2015 Elsevier Masson SAS.

While endoscopically placed gastrostomy tubes are routinely simple, they are not always feasible. Endoscopic technique also does not uniformly secure the tube to the abdominal wall, which presents possible complications, including leakage, accidental early tube removal, intraperitoneal catheter migration and necrosis of the stomach or abdominal wall because of excessive traction. Presented herein is a technique that is rapid, simple and eliminates some of these potential complications. The technique is easily combined with other operative procedures, such as tracheostomy, is done under direct vision, can be performed quickly with intravenous sedation and local anesthetic and is a safe method of tube placement for enteral feeding or gastric decompression.

A higher prevalence of respiratory symptoms and an associated increase in health care utilization among children with parents who smoke is to be expected. From previous studies however, it appears that parents who smoke may underutilize health services for their children, especially with respect to respiratory care. This study explores the validity and generalizability of the previous assumption. Data were obtained from a Dutch birth-cohort study; the Prevention and Incidence of Asthma and Mite Allergy (PIAMA) project. Information regarding parental smoking, the child's respiratory symptoms and health care use and potential confounders were obtained by postal questionnaires. Multivariate logistic models were used to relate parental smoking to the child's respiratory symptoms and health care use. The study comprised 3,564, 4-year old children. In the crude analysis, respiratory symptoms were more frequent among children with a parent who smoked, while health care utilization for respiratory symptoms was not significantly different between children with or without a parent who smoked. In the multivariate analyses, maternal smoking had a larger impact on the child's respiratory symptoms and health care use as compared to paternal smoking. Maternal smoking was positively associated with mild respiratory symptoms of the child, adjusted odds ratio [AOR] 1.50 (1.19-1.91), but not with severe respiratory symptoms AOR 1.03 (0.75-1.40). Among children with mild respiratory symptoms, children with a mother who smoked were less likely to be taken to the general practitioner (GP) for respiratory symptoms, than children with mothers who did not smoke, AOR 0.58 (0.33-1.01). This finding was less pronounced among children with severe respiratory symptoms AOR 0.86 (0.49-1.52). Neither GP visits for non-respiratory symptoms nor specialized care for respiratory disease were significantly associated with parental smoking. Mothers who smoke appear to underutilize health care for their children with mild respiratory symptoms. Health care workers should be informed about this phenomenon. Inquiring after the respiratory health of the children during regular visits to healthy baby clinics may help to track potential underutilization of care.

Fostering sustainable feedstock production for advanced biofuels on underutilised land in Europe

2017-04-01

Background In context of growing competition between land uses, bioenergy development is often seen as one of possible contributors to such competition. However, the potential of underutilized land (contaminated, abandoned, marginal, fallow land etc.) which is not used or cannot be used for productive activities is not exhausted and offers an attractive alternative for sustainable production of different biomass feedstocks in Europe. Depending on biomass feedstocks, different remediation activities can be carried out in addition. Bioenergy crops have the potential to be grown profitably on underutilized land and can therefore offer an attractive source of income on the local level contributing to achieving the targets of the Renewable Energy Directive (EC/2009). The FORBIO project The FORBIO project demonstrates the viability of using underutilised land in EU Member States for sustainable bioenergy feedstock production that does not affect the supply of food, feed and land currently used for recreational or conservation purposes. Project activities will serve to build up and strengthen local bioenergy value chains that are competitive and that meet the highest sustainability standards, thus contributing to the market uptake of sustainable bioenergy in the EU. Presented results The FORBIO project will develop a methodology to assess the sustainable bioenergy production potential on available underutilized lands in Europe at local, site-specific level. Based on this methodology, the project will produce multiple feasibility studies in three selected case study locations: Germany (lignite mining and sewage irrigation fields in the metropolis region of Berlin and Brandenburg), Italy (contaminated land from industrial activities in Sulcis, Portoscuso) and Ukraine (underutilised marginal agricultural land in the North of Kiev). The focus of the presentation will be on the agronomic and techno-economic feasibility studies in Germany, Italy and Ukraine. Agronomic feasibility studies consider agronomic performances in different climatic zones, soil conditions, land morphology, availability of irrigation infrastructures and limitations due to anthropic soil contamination. The outcomes of the techno-economic feasibility studies for the biomasses selected as potentially feasible for underutilized lands in the selected case study locations will be presented.

Update on emergency contraception.

PubMed

Fok, Wing Kay; Blumenthal, Paul D

2016-12-01

Emergency contraception provides a critical and time-sensitive opportunity for women to prevent undesired pregnancy after intercourse. Both access and available options for emergency contraception have changed over the last several years. Emergency contraceptive pills can be less effective in obese women. The maximum achieved serum concentration of levonorgestrel (LNG) is lower in obese women than women of normal BMI, and doubling the dose of LNG (3 mg) increases its concentration maximum, approximating the level in normal BMI women receiving one dose of LNG. Repeated use of both LNG and ulipristal acetate (UPA) is well tolerated. Hormonal contraception can be immediately started following LNG use, but should be delayed for 5 days after UPA use to avoid dampening the efficacy of UPA. The copper intrauterine device (IUD) is the only IUD approved for emergency contraception (and the most effective method of emergency contraception), but use of LNG IUD as emergency contraception is currently being investigated. Accurate knowledge about emergency contraception remains low both for patients and healthcare providers. Emergency contraception is an important yet underutilized tool available to women to prevent pregnancy. Current options including copper IUD and emergency contraceptive pills are safe and well tolerated. Significant gaps in knowledge of emergency contraception on both the provider and user level exist, as do barriers to expedient access of emergency contraception.

Safety, efficacy, and patient acceptability of lidocaine hydrochloride ophthalmic gel as a topical ocular anesthetic for use in ophthalmic procedures

Page, Michael A; Fraunfelder, Frederick W

2009-01-01

Purpose: To review the current literature on safety, efficacy, and measures of surgeon and patient satisfaction with lidocaine hydrochloride gel as a tool for ocular anesthesia. Methods: Pubmed search using keywords “lidocaine gel,” “ophthalmic,” and “surgery” and compiling cross-references. Twenty-six total references were reviewed, including 15 prospective randomized controlled trials (RCTs, total N = 933, average N = 62), 6 nonrandomized prospective studies (total N = 234, average N = 39), 2 animal studies, 1 microbiologic study, and 2 letters to the editor. Results: The RCTs and nonrandomized prospective studies evaluated a number of measures including timing of onset of anesthesia, duration of anesthesia, intraoperative and postoperative pain, need for additional anesthetic applications, intracameral lidocaine levels, and adverse effects. Control groups received topical drops, subconjunctival anesthetic, retrobulbar anesthetic, or sham gel. Lidocaine gel was shown to be at least as effective for pain control as alternative therapies in all studies, with longer duration of action than topical drops. Patient and surgeon satisfaction were high, and adverse effects were rare and comparable to those for anesthetic drop formulations. Surgical settings included cataract, pterygium, trabeculectomy, strabismus, intravitreal injection, vitrectomy, and penetrating keratoplasty. Conclusions: Lidocaine gel is a safe, effective, and potentially underutilized tool for ophthalmic surgery. PMID:19898665

Reasons for Intrauterine Device Use, Discontinuation and Non-Use in Malawi: A Qualitative Study of Women and their Partners.

2015-12-01

The copper intrauterine device (IUD) is a safe, long-acting, and effective method of contraception that is under-utilized in many countries, including Malawi. A unique cohort of women who had enrolled in a trial of postpartum IUD use one year earlier gave insights into reasons for using, discontinuing, or not using the IUD. We conducted in-depth interviews with 18 women one year after they participated in a pilot study of a randomized controlled trial of postpartum IUD insertion, and 10 of their male partners. Women and their partners expressed a strong desire for family planning, and perceived numerous benefits of the IUD. However, fear of the IUD was common among successful users and non-users alike. This fear arose from rumours from friends and neighbors who were non-users. How women and their partners responded to this fear affected IUD adoption and continuation. Key themes included (1) Trust in information received from health care providers versus rumours from community members; (2) Partner involvement in IUD decision-making; and (3) Experience with side effects from short-term hormonal contraceptive methods. Broad community education about the IUD's benefits and safety, and proactive counseling to address couples' specific fears, may be needed to increase uptake of the method.

Effective utilization of clinical laboratories.

PubMed

Murphy, J; Henry, J B

1978-11-01

Effective utilization of clinical laboratories requires that underutilization, overutilization, and malutilization be appreciated and eliminated or reduced. Optimal patient care service, although subjective to a major extent, is reflected in terms of outcome and cost. Increased per diem charges, reduced hospital stay, and increased laboratory workload over the past decade all require each laboratory to examine its internal operations to achieve economy and efficiency as well as maximal effectiveness. Increased research and development, an active managerial role on the part of pathologists, internal self-assessment, and an aggressive response to sophisticated scientific and clinical laboratory data base requirements are not only desirable but essential. The importance of undergraduate and graduate medical education in laboratory medicine to insure understanding as well as effective utilization is stressed. The costs and limitations as well as the accuracy, precision, sensitivity, specificity, and pitfalls of measurements and examinations must also be fully appreciated. Medical malpractice and defensive medicine and the use of critical values, emergency and routine services, and an active clinical role by the pathologist are of the utmost value in assuring effective utilization of the laboratory. A model for the optimal use of the laboratory including economy and efficiency has been achieved in the blood bank in regard to optimal hemotherapy for elective surgery, assuring superior patient care in a cost effective and safe manner.

Elevations in serum creatinine with RAAS blockade: why isn't it a sign of kidney injury?

PubMed

Ryan, Michael J; Tuttle, Katherine R

2008-09-01

The aim of this article is to review the pertinent physiology and pathophysiology of the renin-angiotensin-aldosterone system (RAAS), summarize the proven beneficial cardiovascular and renal effects of RAAS blockade, examine clinical situations in which RAAS blockade may induce reductions in glomerular filtration rate, and explore why increases in serum creatinine in the setting of angiotensin-converting enzyme inhibitor (ACEi) or angiotensin receptor blocker (ARB) therapy do not necessarily signify the presence of clinically relevant kidney failure. RAAS inhibition appears to reduce the likelihood of atrial fibrillation. RAAS inhibition leads to improved insulin sensitivity and glycemic control, but does not appear to prevent diabetes. The beneficial effects of ACEi/ARB therapy extend to those with significant renal disease. Combination ACEi/ARB is safe, and reduces proteinuria more than either agent alone in patients with macroalbuminuric nephropathy. Acute deteriorations in renal function that result from RAAS inhibition are usually reversible. RAAS blockade exerts potent hemodynamic, antihypertensive, and antiinflammatory effects, and slows progression of kidney disease beyond that due to lowering of blood pressure. The benefit extends to those with advanced disease. In spite of established benefit, ACEi and ARB therapy remains underutilized, in part due to concerns about acute deteriorations in renal function that result from interruption of the RAAS.

Youthful females and other disadvantaged minority members sometimes develop visual handicaps when educational and/or other stressors are present. Special methods already available, effective, and underutilized, can be marshaled towards correcting current technologic and academic systems demand-supply mismatches in the sciences. More efficient harvesting of intellectually advantaged youthful students may represent more-highly-productive global scientific output. RDM has found that it is possible to motivate, stimulate, teach, and foster increased science interest by interacting with students at the earliest possible academic moments. The same applied optics of burning paper with a magnifying glass, and prismatic dispersing of light, allows understanding how vision operates, and can be damaged. Providing information to all students that they safely can self-repair damaged vision could only increase their interest in physics and special work-study programs. ``Indians'' are the most poorly represented group at all levels of education and its support services.

2004-01-01

Tubeless PNL (percutaneous nephrolithotomy), in a highly selected group of patients, is a modification aimed at reducing the morbidity of PNL. We present a simple technique of achieving tract hemostasis as an adjunct to the safe performance of a tubeless PNL. Charts of 40 consecutive patients who underwent tubeless PNL at our center were reviewed. In the latter 20 consecutive patients, diathermy coagulation of the intrarenal bleeders and tract was done and these patients were compared with the earlier 20 patients in whom fulguration was not done. Drop in hemoglobin, postoperative analgesic requirement, operating time, length of hospitalization and postoperative complications were compared. No statistical difference was found between the operative times and drop in hemoglobin for both the groups. The length of hospitalization and postoperative analgesic requirement were significantly less in the fulguration group. No significant complications were noted in either of the two groups. Fulguration of visible intrarenal and tract bleeders is a simple, safe and effective hemostatic adjunct in patients undergoing tubeless PNL. copyright 2004 S. Karger AG, Basel

Minimum Control Requirements for Advanced Life Support Systems

Boulange, Richard; Jones, Harry; Jones, Harry

2002-01-01

Advanced control technologies are not necessary for the safe, reliable and continuous operation of Advanced Life Support (ALS) systems. ALS systems can and are adequately controlled by simple, reliable, low-level methodologies and algorithms. The automation provided by advanced control technologies is claimed to decrease system mass and necessary crew time by reducing buffer size and minimizing crew involvement. In truth, these approaches increase control system complexity without clearly demonstrating an increase in reliability across the ALS system. Unless these systems are as reliable as the hardware they control, there is no savings to be had. A baseline ALS system is presented with the minimal control system required for its continuous safe reliable operation. This baseline control system uses simple algorithms and scheduling methodologies and relies on human intervention only in the event of failure of the redundant backup equipment. This ALS system architecture is designed for reliable operation, with minimal components and minimal control system complexity. The fundamental design precept followed is "If it isn't there, it can't fail".

The underutilization of street markets as a source of food security indicators in famine early warning systems: a case study of Ethiopia.

PubMed

Companion, Michèle

2008-09-01

Famine Early Warning Systems (EWS) are reliant on data aggregated from multiple sources. Consequently, they are often insensitive to localized changes in food security status, leading to delayed response or interventions. While price and infrastructural data are often gathered, this case study suggests that local street markets and vendor knowledge are underutilized. Few efforts have been made to monitor systematically the street markets as an indicator of local stressors. Findings from Ethiopia show that knowledge generated by expanding food security indicators in this sector can be used in combination with EWS to facilitate earlier intervention in, or to monitor more effectively, on-going humanitarian crises. Indicators developed from this study are accurate, cost effective, and sensitive to local climatic and food stressors.

A Conceptual Design of a Short Takeoff and Landing Regional Jet Airliner

NASA Technical Reports Server (NTRS)

Hahn, Andrew S.

2010-01-01

Most jet airliner conceptual designs adhere to conventional takeoff and landing performance. Given this predominance, takeoff and landing performance has not been critical, since it has not been an active constraint in the design. Given that the demand for air travel is projected to increase dramatically, there is interest in operational concepts, such as Metroplex operations that seek to unload the major hub airports by using underutilized surrounding regional airports, as well as using underutilized runways at the major hub airports. Both of these operations require shorter takeoff and landing performance than is currently available for airliners of approximately 100-passenger capacity. This study examines the issues of modeling performance in this now critical flight regime as well as the impact of progressively reducing takeoff and landing field length requirements on the aircraft s characteristics.

Political economy of hope as a cultural facet of biomedicalization: A qualitative examination of constraints to hospice utilization among U.S. end-stage cancer patients.

PubMed

Mrig, Emily Hammad; Spencer, Karen Lutfey

2018-03-01

A growing body of social science literature is devoted to describing processes of biomedicalization. The issue of biomedicalization is especially relevant for individuals suffering from end-stage cancer and hoping that aggressive end-of-life interventions, which are riddled with uncertainty around quantity or quality of life, will produce a 'cure'. To examine hospice underutilization among end-stage cancer patients, we apply the anthropological concept 'political economy of hope,' which describes how personal and collective 'hope' is associated with the political and economic structures that produce biomedicalization processes. Previous studies have examined hospice underutilization among end-stage cancer patients and have identified barriers stemming from patient and physician characteristics or health insurance reimbursement policies. Yet, these studies do not provide an organized synthesis of how barriers articulate, how they are part of the longitudinal decision-making process, or describe the sociocultural context surrounding hospice care enrollment decisions. This paper focuses on US-specific mechanisms and is based on qualitative, in-depth, interviews with physicians at an academic hospital (N = 24). We find that hospice underutilization results from a web of interconnected constraints surrounding end-stage cancer patients. Our research reveals how hospice care contradicts the political and economic structures associated with end-stage cancer care and illustrates how end-stage cancer patients are transformed into a form of biovalue, a fundamental commodity sustaining the political economy of hope.

Evidence shows underutilization of cancer genetics services. To explore the reasons behind this underutilization, this study evaluated characteristics of women who were referred for genetic counseling and/or had undergone BRCA1/2 testing. An ovarian cancer risk perception study stratified 16,720 eligible women from the Henry Ford Health System into average-, elevated-, and high-risk groups based on family history. We randomly selected 3,307 subjects and interviewed 2,524 of them (76.3% response rate). Among the average-, elevated-, and high-risk groups, 2.3, 10.1, and 20.2%, respectively, reported genetic counseling referrals, and 0.8, 3.3, and 9.5%, respectively, reported having undergone BRCA testing. Personal breast cancer history, high risk, and perceived ovarian cancer risk were associated with both referral and testing. Discussion of family history with a doctor predicted counseling referral, whereas belief that family history influenced risk was the strongest BRCA testing predictor. Women perceiving their cancer risk as much higher than other women their age were twice as likely (95% confidence interval: 2.0-9.6) to report genetic counseling referral. In a health system with ready access to cancer genetic counseling and BRCA testing, women who were at high risk underutilized these services. There were strong associations between perceived ovarian cancer risk and genetic counseling referral, and between a belief that family history influenced risk and BRCA testing.

Underutilized crops and their wild relatives are important resources for crop improvement and food security. Cempedak [Artocarpus integer (Thunb). Merr.] is a significant crop in Malaysia but underutilized elsewhere. Here we performed molecular characterization of cempedak and its putative wild relative bangkong (Artocarpus integer (Thunb). Merr. var. silvestris Corner) to address questions regarding the origin and diversity of cempedak. Using data from 12 microsatellite loci, we assessed the genetic diversity and genetic/geographic structure for 353 cempedak and 175 bangkong accessions from Malaysia and neighboring countries and employed clonal analysis to characterize cempedak cultivars. We conducted haplotype network analyses on the trnH-psbA region in a subset of these samples. We also analyzed key vegetative characters that reportedly differentiate cempedak and bangkong. We show that cempedak and bangkong are sister taxa and distinct genetically and morphologically, but the directionality of domestication origin is unclear. Genetic diversity was generally higher in bangkong than in cempedak. We found a distinct genetic cluster for cempedak from Borneo as compared to cempedak from Peninsular Malaysia. Finally, cempedak cultivars with the same names did not always share the same genetic fingerprint. Cempedak origins are complex, with likely admixture and hybridization with bangkong, warranting further investigation. We provide a baseline of genetic diversity of cempedak and bangkong in Malaysia and found that germplasm collections in Malaysia represent diverse coverage of the four cempedak genetic clusters detected. © 2018 Botanical Society of America.

To analyse prospectively the effectiveness of a new simple, minimally invasive, and cost-effective technique for the treatment of female urinary stress incontinence: the transfascial vaginal tape (TFT). In a prospective study, we enrolled 45 women undergoing TFT with or without hysterectomy and/or another pelvic reconstructive procedure between 1st December 2003 and 31st December. TFT consists of a tension-free urethrosuspension using a sling located at the mid-urethral level and placed laterally in the endopelvic fascia previously perforated. Follow-up evaluations were established at 3 and 6 months and at 1 year after the operation. During each follow-up, women underwent cough stress test and they answered to the "Incontinence quality of life questionnaire" (I-QOL), to the Patient Global Impression of Severity (PGI-S) and of Improvement (PGI-I) questions. Thirty-nine patients (88.9%) had a follow-up examination 1 year after surgery. Of these, 30 (76.9%) were defined cured, 6 (15.4%) improved and 3 (7.7%) failed. TFT procedure can be considered a simple, safe and cost-effective procedure for the treatment of stress urinary incontinence and can be an alternative to tension-free vaginal tape or transobturator route for sub-urethral tape procedures.

Electrochemical Oxidation (ECO) offers promise as a low-temperature, atmospheric pressure method for safe destruction of hazardous organic chemical wastes in water. Anode materials tend to suffer corrosion in the intensely oxidizing environment of the ECO cell. There is a need for cheaper, more resistant materials. In this experiment, a system is described for testing anode materials, with examples of several common anodes such as stainless steel, graphite, and platinized titanium. The ECO system is simple and safe to operate and the experiment can easily be expanded in scope to study the effects of different solutions, temperatures, and organic materials.

Health systems could obtain substantial cost savings by providing safe abortion care rather than providing expensive treatment for complications of unsafely performed abortions. This study estimates current health system costs of treating unsafe abortion complications and compares these findings with newly-projected costs for providing safe abortion in Malawi. We conducted in-depth surveys of medications, supplies, and time spent by clinical personnel dedicated to postabortion care (PAC) for three treatment categories (simple, severe non-surgical, and severe surgical complications) and three uterine evacuation (UE) procedure types (manual vacuum aspiration (MVA), dilation and curettage (D&C) and misoprostol-alone) at 15 purposively-selected public health facilities. Per-case treatment costs were calculated and applied to national, annual PAC caseload data. The median cost per D&C case ($63) was 29% higher than MVA treatment ($49). Costs to treat severe non-surgical complications ($63) were almost five times higher than those of a simple PAC case ($13). Severe surgical complications were especially costly to treat at $128. PAC treatment in public facilities cost an estimated $314,000 annually. Transition to safe, legal abortion would yield an estimated cost reduction of 20%-30%. The method of UE and severity of complications have a large impact on overall costs. With a liberalized abortion law and implementation of induced abortion services with WHO-recommended UE methods, current PAC costs to the health system could markedly decrease.

2017-02-01

Although psychiatry residents are expected to achieve competency in conducting psychotherapy during their training, it is unclear how psychotherapy teaching is integrated across diverse clinical settings. Between January and March 2015, 177 psychiatry residency training directors were sent a survey asking about psychotherapy training practices in their programs, as well as perceived barriers to psychotherapy teaching. Eighty-two training directors (44%) completed the survey. While 95% indicated that psychotherapy was a formal learning objective for outpatient clinic rotations, fifty percent or fewer noted psychotherapy was a learning objective in other settings. Most program directors would like to see psychotherapy training included (particularly supportive psychotherapy and cognitive behavioral therapy) on inpatient (82%) and consultation-liaison settings (57%). The most common barriers identified to teaching psychotherapy in these settings were time and perceived inadequate staff training and interest. Non-outpatient rotations appear to be an underutilized setting for psychotherapy teaching.

Space use as an indicator of enclosure appropriateness in African wild dogs (Lycaon pictus).

Hunter, Sally C; Gusset, Markus; Miller, Lance J; Somers, Michael J

2014-01-01

A clear understanding of space use is required to more fully understand biological requirements of nonhuman animals in zoos, aid the design of exhibits, and maximize the animals' welfare. This study used electivity indexes to assess space use of two packs of African wild dogs (Lycaon pictus) and the appropriateness of two naturalistic, outdoor enclosures at the San Diego Zoo and Bronx Zoo. The results identified enclosure features that were both underutilized and overutilized. They suggest that replacing underutilized areas with features similar to areas that were overutilized may provide more preferred opportunities for the animals. Assessing space use of animals in human care may serve as an indicator of enclosure appropriateness and could have welfare implications. By looking at the possible reasons for area preferences, animal managers can get an idea of where improvements could be made. Designing future exhibits accordingly thus can provide possible welfare benefits for the animals concerned.

Are Diuretics Underutilized in Dialysis Patients?

PubMed

Trinh, Emilie; Bargman, Joanne M

2016-09-01

While oral diuretics are commonly used in patients with chronic kidney disease for the management of volume and blood pressure, they are often discontinued upon initiation of dialysis. We suggest that diuretics are considerably underutilized in peritoneal dialysis and haemodialysis patients despite numerous potential benefits and few side effects. Moreover, when diuretics are used, optimal doses are not always prescribed. In peritoneal dialysis, the use of diuretics can improve volume status and minimize the need for higher glucose-containing solutions. In patients on haemodialysis, diuretics can help lessen interdialytic weight gain, resulting in decreased ultrafiltration rates and fewer episodes of intradialytic hypotension. This paper will review the mechanism of action of diuretics in patients with renal insufficiency, quantify the risk of side effects and elaborate on the potential advantages of diuretic use in peritoneal dialysis and hemodialysis patients with residual kidney function. © 2016 Wiley Periodicals, Inc.

Catalyzing Social Support for Breast Cancer Patients

PubMed Central

Skeels, Meredith M.; Unruh, Kenton T.; Powell, Christopher; Pratt, Wanda

2010-01-01

Social support is a critical, yet underutilized resource when undergoing cancer care. Underutilization occurs in two conditions: (a) when patients fail to seek out information, material assistance, and emotional support from family and friends or (b) when family and friends fail to meet the individualized needs and preferences of patients. Social networks are most effective when kept up to date on the patient’s status, yet updating everyone takes effort that patients cannot always put in. To improve this situation, we describe the results of our participatory design activities with breast cancer patients. During this process, we uncovered the information a social network needs to stay informed as well as a host of barriers to social support that technology could help break down. Our resulting prototype, built using Facebook Connect, includes explicit features to reduce these barriers and thus, promote the healthy outcomes associated with strong social support. PMID:21654894

2017-04-01

Atrial fibrillation affects 33.5 million people worldwide and its prevalence is expected to double by 2050 because of the aging population. Atrial fibrillation confers a 5-fold higher risk of ischemic stroke compared to sinus rhythm. We present our view of the role of shared medical decision-making to combat global underutilization of oral anticoagulation for stroke prevention in atrial fibrillation patients. Oral anticoagulation underuse is widespread as it is present within atrial fibrillation patients of all risk strata and in countries across all income levels. Reasons for oral anticoagulation underuse include but are probably not limited to poor risk stratification, over-interpretation of contraindications, and discordance between physician prescription preferences and actual administration. By comparing a catastrophic event to the consequences of atrial fibrillation related strokes, it may help physicians and patients understand the negative outcomes associated with oral anticoagulation under-utilization and the magnitude to which oral anticoagulations neutralize atrial fibrillation burden.

Comparative study of fruit morphology, architecture, and juice yield productivity revealed that fruit berries of Seabuckthorn in Mana valley was found superior and can provide higher economic return than the berries of other plant species. Moreover, awareness programmes related to nutritional worth and development and demonstration of value added product resulted in economy generation for local inhabitants. Several countries are commercially and ecologically harnessing the potential of Seabuckthorn for livelihood enhancement and environmental conservation. Correspondingly, in Indian Himalayan region, Seabuckthorn plant can also offer benefits of nutrition, food, medicine, cosmetic, etc., to the rural people for their socioeconomic development. Findings presented here have important connotations in light of upcoming organic food and nutraceutical industries in the country. The current study will also help in developing value chain of Seabuckthorn in Uttarakhand.

In our previous work, we demonstrated underutilization of the AIDS Drug Assistance Program (ADAP) at an HIV clinic in Alabama. In order to understand barriers and facilitators to utilization of ADAP, we conducted focus groups of ADAP enrollees. Focus groups were stratified by sex, race, and historical medication possession ratio as a measure of program utilization. We grouped factors according to the social-ecological model. We found that multiple levels of influence, including patient and clinic-related factors, influenced utilization of antiretroviral medications. Patients introduced issues that illustrated high-priority needs for ADAP policy and implementation, suggesting that in order to improve ADAP utilization, the following issues must be addressed: patient transportation, ADAP medication refill schedules and procedures, mailing of medications, and the ADAP recertification process. These findings can inform a strategy of approaches to improve ADAP utilization, which may have widespread implications for ADAP programs across the United States. PMID:24503498

Background: Public district hospitals (PDHs) in Tunisia are not operating at full plant capacity and underutilize their operating budget. Methods: Individual PDHs capacity utilization (CU) is measured for 2000 and 2010 using dual data envelopment analysis (DEA) approach with shadow prices input and output restrictions. The CU is estimated for 101 of 105 PDH in 2000 and 94 of 105 PDH in 2010. Results: In average, unused capacity is estimated at 18% in 2010 vs. 13% in 2000. Of PDHs 26% underutilize their operating budget in 2010 vs. 21% in 2000. Conclusion: Inadequate supply, health quality and the lack of operating budget should be tackled to reduce unmet user’s needs and the bypassing of the PDHs and, thus to increase their CU. Social health insurance should be turned into a direct purchaser of curative and preventive care for the PDHs. PMID:28005538

METHOD OF CONDUCTING A PERSON BETWEEN A SAFE REGION AND A DANGEROUS REGION

DOEpatents

Moulthrop, H.A.

1957-11-12

This invention relates to a method for conducting a person between a safe region and a dangerous or con taminated region so that he may work in the dangerous region without risk to himself or the hinderance of an attached tube, and without danger of contaminating the safe region. A safely suit in which a person is to work is connected by a thermoplastic tube, turned partially inside out, to a hole in the wall separating the dangerous region. The tube is sealed by pressure and separated into two parts at the seal, whereupon the person in the suit may move around freely in the dangerous area. When the person desires to exit the dangerous region, the parts of the tube are resealed, removing a portion of the tube at the seal, and the person leaves the hole whcre he entered, seals the tube to close the hole, and cuts his suit free from the tube. Bands of masking tape inside and outside of the tube at predetermined points simplify the pressure sealing of the tube at the desired points. This patent provides a simple, safe and economical method of freely working in a dangerous region.

Background: Data on the use of emergency medical services (EMS) by patients with cardiac conditions in the Gulf region are scarce, and prior studies have suggested underutilization. Patient perception and knowledge of EMS care is critical to proper utilization of such services. Objectives: To estimate utilization, knowledge, and perceptions of EMS among patients with ST-elevation myocardial infarction (STEMI) in the Emirate of Abu Dhabi. Methods: We conducted a multicenter prospective study of consecutive patients admitted with STEMI in four government-operated hospitals in Abu Dhabi. Semi-structured interviews were conducted with patients to assess the rationale for choosing their prehospital mode of transport and their knowledge of EMS services. Results: Of 587 patients with STEMI (age 51 ± 11 years, male 95%), only 15% presented through EMS, and the remainder came via private transport. Over half of the participants (55%) stated that they did not know the telephone number for EMS. The most common reasons stated for not using EMS were that private transport was quicker (40%) or easier (11%). A small percentage of participants (7%) did not use EMS because they did not think their symptoms were cardiac-related or warranted an EMS call. Stated reasons for not using EMS did not significantly differ by age, gender, or primary language of the patients. Conclusions: EMS care for STEMI is grossly underutilized in Abu Dhabi. Patient knowledge and perceptions may contribute to underutilization, and public education efforts are needed to raise their perception and knowledge of EMS. PMID:27512532

Accounting for misclassification error in retrospective smoking data.

Kenkel, Donald S; Lillard, Dean R; Mathios, Alan D

2004-10-01

Recent waves of major longitudinal surveys in the US and other countries include retrospective questions about the timing of smoking initiation and cessation, creating a potentially important but under-utilized source of information on smoking behavior over the life course. In this paper, we explore the extent of, consequences of, and possible solutions to misclassification errors in models of smoking participation that use data generated from retrospective reports. In our empirical work, we exploit the fact that the National Longitudinal Survey of Youth 1979 provides both contemporaneous and retrospective information about smoking status in certain years. We compare the results from four sets of models of smoking participation. The first set of results are from baseline probit models of smoking participation from contemporaneously reported information. The second set of results are from models that are identical except that the dependent variable is based on retrospective information. The last two sets of results are from models that take a parametric approach to account for a simple form of misclassification error. Our preliminary results suggest that accounting for misclassification error is important. However, the adjusted maximum likelihood estimation approach to account for misclassification does not always perform as expected. Copyright 2004 John Wiley & Sons, Ltd.

A buoyant tornado-probe concept incorporating an inverted lifting device. [and balloon combination

NASA Technical Reports Server (NTRS)

Grant, F. C.

1973-01-01

Addition of an inverted lifting device to a simple balloon probe is shown to make possible low-altitude entry to tornado cores with easier launch conditions than for the simple balloon probe. Balloon-lifter combinations are particularly suitable for penetration of tornadoes with average to strong circulation, but tornadoes of less than average circulation which are inaccessible to simple balloon probes become accessible. The increased launch radius which is needed for access to tornadoes over a wide range of circulation results in entry times of about 3 minutes. For a simple balloon probe the uninflated balloon must be first dropped on, or near, the track of the tornado from a safe distance. The increase in typical launch radius from about 0.75 kilometer to slightly over 1.0 kilometer with a balloon-lifter combination suggests that a direct air launch may be feasible.

2016-01-01

Encouraged by the creation of the Office of Commercial Space Transportation within the U.S. Federal Aviation Administration (FAA) in 1984 and the Commercial Space Act of 1998, the National Aeronautics and Space Administration (NASA) now relies on an extensive network of support from commercial companies and organizations. At NASA's Kennedy Space Center (KSC), this collaboration opens competitive opportunities for launch providers, including repurposing underutilized Shuttle Program resources, constructing new facilities, and utilizing center services and laboratories. The resulting multi-user spaceport fosters diverse activity, though it engenders risk from hazards associated with various spaceflight processing activities. The KSC Safety & Mission Assurance (S&MA) Directorate, in coordination with the center's Spaceport Integration and Center Planning & Development organizations, has developed a novel approach to protect NASA's workforce, critical assets, and the public from hazardous, space-related activity associated with KSC's multi-user spaceport. For NASA KSC S&MA, the transformation to a multi-user spaceport required implementing methods to foster safe and successful commercial activity while resolving challenges involving: Retirement of the Space Shuttle program; Co-location of multiple NASA programs; Relationships between the NASA programs; Complex relationships between NASA programs and commercial partner operations in exclusive-use facilities; Complex relationships between NASA programs and commercial partner operations in shared-use facilities. NASA KSC S&MA challenges were met with long-term planning and solutions involving cooperation with the Spaceport Integration and Services Directorate. This directorate is responsible for managing active commercial partnerships with customer advocacy and services management, providing a dedicated and consistent level of support to a wide array of commercial operations. This paper explores these solutions, their relevance to the current commercial space industry, and the challenges that continue to drive improvement with a focus on areas of safety management and risk assessment that have been crucial in KSC's evolution into a multi-user spaceport. These solutions may be useful to government entities and private companies looking to partner with the commercial space industry.

Acarbose: safe and effective for lowering postprandial hyperglycaemia and improving cardiovascular outcomes

PubMed Central

DiNicolantonio, James J; Bhutani, Jaikrit; O'Keefe, James H

2015-01-01

α-Glucosidase inhibitors (AGIs) are a class of oral glucose-lowering drugs used exclusively for treatment or prevention of type 2 diabetes mellitus. AGIs act by altering the intestinal absorption of carbohydrates through inhibition of their conversion into simple sugars (monosaccharides) and thus decrease the bioavailability of carbohydrates in the body, significantly lowering blood glucose levels. The three AGIs used in clinical practice are acarbose, voglibose and miglitol. This review will focus on the cardiovascular properties of acarbose. The current available data suggest that AGIs (particularly acarbose) may be safe and effective for the treatment of prediabetes and diabetes. PMID:26512331

The results of this study show that the oral administration of ivermectin (48 mg/L) repeatedly for 72 h used in accordance with the present protocol is a safe and highly effective treatment for Giardia spp. and Hymenolepis nana in laboratory rat colonies. The drug can be easily and safely administered using drinking water. This simple regimen should control pinworm infection (Syphacia muris), a problem that can be endemic in laboratory colonies. Experiments using healthy animals are likely to generate more consistent results, thereby requiring a reduced number of animals per group. © The Author(s) 2014.

Ultrasound-guided drainages and sclerotherapy.

PubMed

Lohela, P

2002-02-01

Ultrasonically guided fluid collection and abscess drainage have become routine procedures in various parts of the body. In most cases ultrasound is the only imaging and guidance modality needed; however, it is of the utmost importance to remember that CT and fluoroscopy with contrast often give invaluable information when the true extent of the process has to be determined and when assessing the safest route for the catheter in anatomically complicated areas. The importance of irrigation of the abscess cavity with fluids and the ready use of urokinase should be emphasized. Ethanol sclerotherapy is a simple and safe procedure to treat symptomatic hepatic or renal cysts. Parathyroid adenomas and cysts, as well as thyroid cysts, can also be treated with ethanol sclerotherapy in selected cases. Purified mineral talc has been used in pleurodesis and hydrocele sclerotherapy, whereas doxycycline or ethanol is used for postoperative lymphoceles. Both abscess drainages and sclerotherapy procedures are minimally invasive, simple, safe, inexpensive and reasonably efficacious treatment in many clinical instances and may be at least an alternative to surgical treatment, often offering significant advantages over surgery.

A simple technique of laparoscopic port closure allowing wound extension.

PubMed

Christey, G R; Poole, G

2002-04-01

Reliable and safe access to the abdominal cavity and efficient removal of the resected gallbladder are essential to laparoscopic cholecystectomy. The unpredictable size of the cholecystectomy specimen can sometimes lead to frustration at the time of removal. A simple technique has been developed that allows for tissue extraction and easy fascial closure regardless of the size of the specimen. This is achieved by using a four bite "U-shaped" purse string at the time of Hasson insertion, with cephalad advancement of the proximal two bites. This allows for variable wound extension and secure closure, without the need for additional sutures.

Safe and effective immunologic adjuvants are often essential for vaccines. However, the choice of adjuvant for licensed vaccines is limited, especially for those that are administered intradermally. We show that non-tissue damaging, near-infrared (NIR) laser light given in short exposures to small areas of skin, without the use of additional chemical or biological agents, significantly increases immune responses to intradermal influenza vaccination without augmenting IgE. The NIR laser-adjuvanted vaccine confers increased protection in a murine influenza lethal challenge model as compared to unadjuvanted vaccine. We show that NIR laser treatment induces the expression of specific chemokines in the skin resulting in recruitment and activation of dendritic cells and is safe to use in both mice and humans. The NIR laser adjuvant technology provides a novel, safe, low-cost, simple-to-use, potentially broadly applicable and clinically feasible approach to enhancing vaccine efficacy as an alternative to chemical and biological adjuvants.

Risk Assessment and Hierarchical Risk Management of Enterprises in Chemical Industrial Parks Based on Catastrophe Theory

PubMed Central

Chen, Yu; Song, Guobao; Yang, Fenglin; Zhang, Shushen; Zhang, Yun; Liu, Zhenyu

2012-01-01

According to risk systems theory and the characteristics of the chemical industry, an index system was established for risk assessment of enterprises in chemical industrial parks (CIPs) based on the inherent risk of the source, effectiveness of the prevention and control mechanism, and vulnerability of the receptor. A comprehensive risk assessment method based on catastrophe theory was then proposed and used to analyze the risk levels of ten major chemical enterprises in the Songmu Island CIP, China. According to the principle of equal distribution function, the chemical enterprise risk level was divided into the following five levels: 1.0 (very safe), 0.8 (safe), 0.6 (generally recognized as safe, GRAS), 0.4 (unsafe), 0.2 (very unsafe). The results revealed five enterprises (50%) with an unsafe risk level, and another five enterprises (50%) at the generally recognized as safe risk level. This method solves the multi-objective evaluation and decision-making problem. Additionally, this method involves simple calculations and provides an effective technique for risk assessment and hierarchical risk management of enterprises in CIPs. PMID:23208298

National General Aviation Roadmap for a Small Aircraft Transportation System (SATS)

NASA Technical Reports Server (NTRS)

Holmes, Bruce J.

2000-01-01

The National Aeronautics and Space Administration (NASA), Federal Aviation Administration, as well as state, industry, and academia partners have joined forces to pursue the NASA National General Aviation Roadmap leading to a Small Aircraft Transportation System (SATS). This long-term strategic undertaking has a goal to bring next-generation technologies and improve air access to small communities. The envisioned outcome is to improve travel between remote communities and transportation centers in urban areas by utilizing a new generation of single-pilot light planes for personal and business transportation between the nation's 5,400 public use general aviation airports. Current NASA investments in aircraft technologies are enabling industry to bring affordable, safe, and easy-to-use features to the marketplace, including "Highway in the Sky" glass cockpit operating capabilities, affordable crash worthy composite airframes, more efficient IFR flight training, and revolutionary engines. To facilitate this initiative, a comprehensive upgrade of public infrastructure must be planned, coordinated, and implemented within the framework of the national air transportation system. State partnerships are proposed to coordinate research support in key public infrastructure areas. Ultimately, SATS may permit more than tripling aviation system throughput capacity by tapping the under-utilized general aviation facilities to achieve the national goal of doorstep-to-destination travel at four times the speed of highways for the nation's suburban, rural, and remote communities.

2015-04-01

The present study investigated five cyclodextrins (CDs) for the extraction of flavonols from apple pomace powder and optimized β-CD based extraction of total flavonols using response surface methodology. A 2(3) central composite design with β-CD concentration (0-5 g 100 mL(-1)), extraction temperature (20-72 °C), extraction time (6-48 h) and second-order quadratic model for the total flavonol yield (mg 100 g(-1) DM) was selected to generate the response surface curves. The optimal conditions obtained were: β-CD concentration, 2.8 g 100 mL(-1); extraction temperature, 45 °C and extraction time, 25.6 h that predicted the extraction of 166.6 mg total flavonols 100 g(-1) DM. The predicted amount was comparable to the experimental amount of 151.5 mg total flavonols 100 g(-1) DM obtained from optimal β-CD based parameters, thereby giving a low absolute error and adequacy of fitted model. In addition, the results from optimized extraction conditions showed values similar to those obtained through previously established solvent based sonication assisted flavonol extraction procedure. To the best of our knowledge, this is the first study to optimize aqueous β-CD based flavonol extraction which presents an environmentally safe method for value-addition to under-utilized bio resources.

Community pharmacists are the third largest healthcare professional group in the world after physicians and nurses. Despite their considerable training, community pharmacists are the only health professionals who are not primarily rewarded for delivering health care and hence are under-utilized as public health professionals. An emerging consensus among academics, professional organizations, and policymakers is that community pharmacists, who work outside of hospital settings, should adopt an expanded role in order to contribute to the safe, effective, and efficient use of drugs-particularly when caring for people with multiple chronic conditions. Community pharmacists could help to improve health by reducing drug-related adverse events and promoting better medication adherence, which in turn may help in reducing unnecessary provider visits, hospitalizations, and readmissions while strengthening integrated primary care delivery across the health system. This paper reviews recent strategies to expand the role of community pharmacists in Australia, Canada, England, the Netherlands, Scotland, and the United States. The developments achieved or under way in these countries carry lessons for policymakers world-wide, where progress thus far in expanding the role of community pharmacists has been more limited. Future policies should focus on effectively integrating community pharmacists into primary care; developing a shared vision for different levels of pharmacist services; and devising new incentive mechanisms for improving quality and outcomes.

2007-01-01

Oca (Oxalis tuberosa Mol.) is an under-utilized tuber crop from the Andean region. Cryopreservation would allow the safe and long-term preservation of the genetic resources of this crop. A protocol for the cryopreservation of in vitro grown shoots has been developed using the vitrification solution PVS2. Two genotypes were studied (G1 and G27). Nodal segments were cultured on MS medium and incubated at 10 degree C with 16 h photoperiod and 10 mol per square meter per second irradiance, for two weeks. Apices were then excised and cultured on MS+0.15 M sucrose for 3 days at 5 degree C in darkness. Subsequently, apices were immersed in a loading solution (liquid MS medium+2 M glycerol+0.4 M sucrose), and then treated with the vitrification solution PVS2 for 0 to 40 minutes. Cryovials were then immersed in liquid nitrogen. Four weeks after rewarming and culture on recovery medium, genotype G1 showed approximately 60 percent recovery (normal growth) with 20 min PVS2 treatment. Genotype G27 showed lower recovery (30 percent). Differential scanning calorimetry yielded a Tg midpoint for PSV2 solution of ca. -120 degree C. Calorimetric studies on apices at different stages of the cryopreservation protocol showed a change in calorimetric parameters consistent with a decrease in the amount of frozen water as the protocol advanced.

Fluorescein sodium is one of the fluorophores that is used in the resection of intracranial lesions. It is commonly used along with a customized microscope, which is expensive and not available universally. In this study, we describe a simple, inexpensive method for better visualization of intracranial and spinal cord lesions with fluorescein. After a test dose, 20 mg/kg of fluorescein sodium was administered intravenously at the time of intubation. A blue light source was used before resection for precise localization of the intracranial lesions after durotomy. Most of the resection was done under the white light, while the blue light was used intermittently to delineate the pathologic tissue from the normal tissue and to ensure safe maximal resection. The intensity of fluorescein staining under white light and blue light was noted. The study comprised 40 cases of gliomas, meningiomas, abscesses, spinal cord tumors, and cerebellopontine angle lesions. Thirty-five lesions showed good fluorescence under the blue light, which helped us achieve better resection of the pathologic lesions. Fluorescein sodium is a safe dye; it can be used to aid in precise localization and safe maximal resection of the pathologic tissue with the help of a blue light source at any center with challenged resources. The blue light enhances the fluorescence and visualization of the pathologic tissue, and this technique can be adopted by any surgeon without much difficulty even with a basic neurosurgical setup.

Zeng, L-C; Du, Y; Yang, H-F; Xie, M-G; Liao, H-Q; Zhang, Y-D; Li, L; Wang, Q; Hu, L

2015-01-01

Objective: To evaluate the efficacy of aspiration in an opposite position to deal with pneumothorax after CT-guided lung biopsy. Methods: A retrospective study was developed involving 210 patients with pneumothorax who had undergone CT-guided percutaneous core biopsies from January 2012 to March 2014 for various pulmonary lesions. Asymptomatic patients with minimal pneumothorax were treated conservatively. Simple manual aspiration was performed for symptomatic patients with minimal pneumothorax and for all patients with moderate to large pneumothorax. An opposite position aspiration was performed when simple manual aspiration failed. The efficacy of simple manual aspiration and the opposite position aspiration was observed. Results: Among 210 patients with pneumothorax, 128 (61.0%) asymptomatic patients with minimal pneumothorax were treated conservatively. The remaining 82 were treated with attempted simple manual aspiration. Out of these 82 patients, simple manual aspiration was successful in 58 (70.7%, 58/82) cases. The complete and partial regression rates were 17.2% (10/58) and 82.8% (48/58), respectively. In the other 24 patients (29.3%, 24/82), simple aspiration technique was ineffective. An opposite position (from prone to supine or vice versa) was applied, and a new biopsy puncture site was chosen for reaspiration. This procedure was successful in 22 patients but not in 2 patients who had to have a chest tube insertion. The complete and partial regression rates were 25.0% (6/24) and 66.7% (16/24), respectively. Applying the new method, the total effective rate of aspiration improved significantly from 70.7% (58/82) to 97.6% (80/82). Conclusion: The opposite position aspiration can be safe, effective and minimally invasive treatment for CT-guided lung biopsy-induced pneumothorax thus reducing the use of chest tube significantly. Advances in knowledge: (1) Opposite position aspiration can elevate the success rate of aspiration significantly (from 70.7% to 97.6% in our study); (2) this procedure is a safe, effective and minimally invasive treatment for pneumothorax caused by biopsy; and (3) opposite position aspiration is a useful technique to reduce the use of chest tube, which has clinical significance.

Setting the Clock for Fail-Safe Early Embryogenesis.

PubMed

Fickentscher, Rolf; Struntz, Philipp; Weiss, Matthias

2016-10-28

The embryogenesis of the small nematode Caenorhabditis elegans is a remarkably robust self-organization phenomenon. Cell migration trajectories in the early embryo, for example, are well explained by mechanical cues that push cells into positions where they experience the least repulsive forces. Yet, how this mechanically guided progress in development is properly timed has remained elusive so far. Here, we show that cell volumes and division times are strongly anticorrelated during the early embryogenesis of C. elegans with significant differences between somatic cells and precursors of the germline. Our experimental findings are explained by a simple model that in conjunction with mechanical guidance can account for the fail-safe early embryogenesis of C. elegans.

2011-12-01

The objective of this experiment was not only to provide a simple residue analytical method to evaluate the safe application rate of Emamectin Benzoate for paddy crops but also to give a suitable recommended dosage in paddy crops. Paddy samples were detected using HPLC-MS/MS. The half-lives of emamectin benzoate in paddy plants, water and soil were 2.04-8.66 days, 2.89-4.95 days and 3.65-5.78 days with a dissipation rate of 90% over 7 days after application, respectively. Low residues and short half-life suggested that Emamectin Benzoate could be safely used in paddy crops with the suitable dosage and application.

Fitz, Nicholas S; Reiner, Peter B

2015-01-01

Transcranial direct current stimulation (tDCS), a simple means of brain stimulation, possesses a trifecta of appealing features: it is relatively safe, relatively inexpensive and relatively effective. It is also relatively easy to obtain a device and the do-it-yourself (DIY) community has become galvanised by reports that tDCS can be used as an all-purpose cognitive enhancer. We provide practical recommendations designed to guide balanced discourse, propagate norms of safe use and stimulate dialogue between the DIY community and regulatory authorities. We call on all stakeholders—regulators, scientists and the DIY community—to share in crafting policy proposals that ensure public safety while supporting DIY innovation. PMID:23733050

We demonstrate a range imaging pulsed laser sensor with two-dimensional scanning of a transmitted beam and a scanless receiver using a high-aspect avalanche photodiode (APD) array for the eye-safe wavelength. The system achieves a high frame rate and long-range imaging with a relatively simple sensor configuration. We developed a high-aspect APD array for the wavelength of 1.5 μm, a receiver integrated circuit, and a range and intensity detector. By combining these devices, we realized 160×120 pixels range imaging with a frame rate of 8 Hz at a distance of about 50 m.

Vial OrganicTM-Organic Chemistry Labs for High School and Junior College

NASA Astrophysics Data System (ADS)

Russo, Thomas J.; Meszaros, Mark

1999-01-01

Vial Organic is the most economical, safe, and time-effective method of performing organic chemistry experiments. Activities are carried out in low-cost, sealed vials. Vial Organic is extremely safe because only micro quantities of reactants are used, reactants are contained in tightly sealed vials, and only water baths are used for temperature control. Vial Organic laboratory activities are easily performed within one 50-minute class period. When heat is required, a simple hot-water bath is prepared from a beaker of water and an inexpensive immersion heater. The low cost, ease of use, and relatively short time requirement will allow organic chemistry to be experienced by more students with less confusion and intimidation.

The screening of lesser-known underutilized seeds as source of food has been a way of finding solution to food insecurity in developing nations. In this regard, oil as a class of food was extracted from the seeds of Diospyros mespiliformis  (4.72 ± 0.2%), Albizia lebbeck  (6.40 ± 0.60%), and Caesalpinia pulcherrima  (7.2 ± 0.30%). The oils were finally analyzed for their fatty acid composition, lipid classes, fatty acid distribution in the lipid fractions, and molecular speciation of the triacylglycerols, glycolipids, and phospholipids. The fatty acid composition of the oils varied with C18:2 fatty acid being the most dominant in the oils. Neutral lipids were the most abundant lipid class found in the oils while molecular species of the triacylglycerol with equivalent carbon chain number C40 was majorly present in the oils of Diospyros mespiliformis and Caesalpinia pulcherrima. The present study presents lesser-known underutilized seeds as possible sources of food.

PubMed Central

Herschell, Amy D.; Kolko, David J.; Baumann, Barbara L.; Davis, Abigail C.

2010-01-01

Evidence-based treatments (EBT) are underutilized in community settings, where consumers are often seen for treatment. Underutilization of EBTs may be related to a lack of empirically informed and supported training strategies. The goals of this review are to understand the state of the literature for training therapists in psychotherapy skills and to offer recommendations to improve research in this area. Results of this review of 55 studies evaluating six training methods indicate that multi-component trainings have been studied most often and have most consistently demonstrated positive training outcomes relative to other training methods. Studies evaluating utility of reading, self-directed trainings, and workshops have documented that these methods do not routinely produce positive outcomes. Workshop follow-ups help to sustain outcomes. Little is known about the impact of train-the-trainer methods. Methodological flaws and factors that may influence training outcome and future directions are also reviewed. PMID:20304542

Six underutilized legume seeds grown in Nigeria namely, red and white lima beans, brown and cream pigeon pea, African yam bean and jackbean were analysed for different anti-nutritional factors Sojasapogenol B was identified as the predominant sapogenol in lima beans and jackbeans by capillary gas chromatography. The content of total inositol phosphates and individual inositol phosphates (IP6, IP5, IP4 and IP3) were analysed by ion-pair HPLC, being in the range of other legumes. Trace quantities of lupanine were identified as the alkaloid in jackbean. alpha-Galactosides were present in all the legume seeds, stachyose being the predominant galactoside in lima beans, African yam bean and jackbean, and verbascose in pigeon pea. The haemagglutinating activity was estimated as a measure of the lectin content of the samples. African yam bean was found to have the highest heamagglutinating activity. Tannins were found to be in low quantities. The presence of these anti-nutrients in relation to the nutritional value of the legume is discussed.

The aim of the study was to evaluate, in a sample of young asthmatics in Italy, the current practice in assessment and treatment of asthma after the publication of guidelines. Young soldiers who declared bronchial asthma at the beginning of the compulsory military service were evaluated. One-hundred and thirty-eight subjects with confirmed asthma were selected. Sixty-seven subjects (48.5%) had had at last one spirometry, and only one subject had underwent peak flow monitoring at home; most of the subjects (96.8%) had had prick tests. More of the 50% of the subjects with bronchial obstruction or with severe bronchial hyperresponsiveness, with clinical moderate or severe asthma, had used only bronchodilators or no therapy at all in the preceding year. In this sample of young asthmatics, the lung function tests were still underutilized for the diagnosis and follow-up of bronchial asthma; moreover, the inhaled anti-inflammatory drugs were still underutilized.

Dry and fresh apples have been studied monitoring their polyphenolic profiles through 1 H NMR, antioxidant capacity and total polyphenol content. Six ancient and underutilized apple varieties (Mantovana, Mora, Nesta, Cipolla, Ruggina, Sassola) and a commercial one (Golden Delicious) were dried with an air-drying system at 45°C for 19h. Although some of their polyphenol constituents were lost during drying, the antioxidant capacity of some apple varieties remained higher compared to Golden Delicious. This result is very important for ancient and underutilized varieties that are not consumed on large scale as fresh product since they have low attractiveness, due to their ugly appearance. Combining quantitative NMR spectroscopy with principal component analysis we have identified and quantified several polyphenols (such as catechin, epicathechin, and chlorogenic acid) that are important to establish the nutraceutical value of the different investigated apple varieties.

Bacterial biodegradation and bioconversion of industrial lignocellulosic streams.

PubMed

Mathews, Stephanie L; Pawlak, Joel; Grunden, Amy M

2015-04-01

Lignocellulose is a term for plant materials that are composed of matrices of cellulose, hemicellulose, and lignin. Lignocellulose is a renewable feedstock for many industries. Lignocellulosic materials are used for the production of paper, fuels, and chemicals. Typically, industry focuses on transforming the polysaccharides present in lignocellulose into products resulting in the incomplete use of this resource. The materials that are not completely used make up the underutilized streams of materials that contain cellulose, hemicellulose, and lignin. These underutilized streams have potential for conversion into valuable products. Treatment of these lignocellulosic streams with bacteria, which specifically degrade lignocellulose through the action of enzymes, offers a low-energy and low-cost method for biodegradation and bioconversion. This review describes lignocellulosic streams and summarizes different aspects of biological treatments including the bacteria isolated from lignocellulose-containing environments and enzymes which may be used for bioconversion. The chemicals produced during bioconversion can be used for a variety of products including adhesives, plastics, resins, food additives, and petrochemical replacements.

Goddard Earth Sciences Data and Information Services Center (GES DISC) has been providing access to scientific data sets since 1990s. Beginning as one of the first Earth Observing System Data and Information System (EOSDIS) archive centers, GES DISC has evolved to offer a wide range of science-enabling services. With a growing understanding of needs and goals of its science users, GES DISC continues to improve and expand on its broad set of data discovery and access tools, sub-setting services, and visualization tools. Nonetheless, the multitude of the available tools, a partial overlap of functionality, and independent and uncoupled interfaces employed by these tools often leave the end users confused as of what tools or services are the most appropriate for a task at hand. As a result, some the services remain underutilized or largely unknown to the users, significantly reducing the availability of the data and leading to a great loss of scientific productivity. In order to improve the accessibility of GES DISC tools and services, we have designed and implemented UUI, the Unified User Interface. UUI seeks to provide a simple, unified, and intuitive one-stop shop experience for the key services available at GES DISC, including sub-setting (Simple Subset Wizard), granule file search (Mirador), plotting (Giovanni), and other services. In this poster, we will discuss the main lessons, obstacles, and insights encountered while designing the UUI experience. We will also present the architecture and technology behind UUI, including NodeJS, Angular, and Mongo DB, as well as speculate on the future of the tool at GES DISC as well as in a broader context of the Space Science Informatics.

Whereas the importance of family history (FH) is widely recognized in cardiovascular risk assessment, its full potential could be underutilized, when applied with its current simple guidelines-based definition (cFH): presence of premature cardiovascular disease (CVD) in a first-degree relative. We tested the added value of a new, extended family history definition (eFH), also taking into account later onset of disease, second-degree relatives and number of affected relatives, on profiling cardiovascular risk and atherosclerotic burden in the general population. Longitudinal population study. Random, representative population sample from Erpe-Mere and Nieuwerkerken (Belgium, primary care). 2524 male/female volunteers, aged 35-55 years, free from overt CVD. Subjects were extensively phenotyped including presence of atherosclerosis (ultrasound) and a newly developed FH questionnaire (4 generations). Compared to cFH, eFH was superior in predicting an adverse risk profile (glycemic state, elevated blood pressure, lipid abnormalities, presence of metabolic syndrome components) and presence of atherosclerosis (all age & sex-adjusted p<0.05). Unlike cFH, eFH remained a significant predictor of subclinical atherosclerosis after adjusting for confounders. Most relations with eFH were not graded but showed clear informational breakpoints, with absence of CVD (including late onset) in any first-degree relative being a negative predictor of atherosclerosis, and a particularly interesting phenotype for further study. A novel, extended FH definition is superior to the conventional definition in profiling cardiovascular risk and atherosclerotic burden in the general population. There remain clear opportunities to refine and increase the performance and informational content of this simple, readily-available inexpensive tool.

Caudal blocks are performed through the sacral hiatus in order to provide pain control in children undergoing lower abdominal surgery. During the block, it is important to avoid advancing the needle beyond the sacrococcygeal ligament too much to prevent unintended dural puncture. This study used demographic data to establish simple guidelines for predicting a safe needle depth in the caudal epidural space in children. A total of 141 children under 12 years old who had undergone lumbar-sacral magnetic resonance imaging were included. The T2 sagittal image that provided the best view of the sacrococcygeal membrane and the dural sac was chosen. We used Picture Achieving and Communication System (Centricity ® PACS, GE Healthcare Co.) to measure the distance between the sacrococcygeal ligament and the dural sac, the length of the sacrococcygeal ligament, and the maximum depth of the caudal space. There were strong correlations between age, weight, height, and BSA, and the distance between the sacrococcygeal ligament and dural sac, as well as the length of the sacrococcygeal ligament. Based on these findings, a simple formula to calculate the distance between the sacrococcygeal ligament and dural sac was developed: 25 × BSA (mm). This simple formula can accurately calculate the safe depth of the caudal epidural space to prevent unintended dural puncture during caudal block in children. However, further clinical studies based on this formula are needed to substantiate its utility. © 2017 John Wiley & Sons Ltd.

Image color reduction method for color-defective observers using a color palette composed of 20 particular colors

NASA Astrophysics Data System (ADS)

Sakamoto, Takashi

2015-01-01

This study describes a color enhancement method that uses a color palette especially designed for protan and deutan defects, commonly known as red-green color blindness. The proposed color reduction method is based on a simple color mapping. Complicated computation and image processing are not required by using the proposed method, and the method can replace protan and deutan confusion (p/d-confusion) colors with protan and deutan safe (p/d-safe) colors. Color palettes for protan and deutan defects proposed by previous studies are composed of few p/d-safe colors. Thus, the colors contained in these palettes are insufficient for replacing colors in photographs. Recently, Ito et al. proposed a p/dsafe color palette composed of 20 particular colors. The author demonstrated that their p/d-safe color palette could be applied to image color reduction in photographs as a means to replace p/d-confusion colors. This study describes the results of the proposed color reduction in photographs that include typical p/d-confusion colors, which can be replaced. After the reduction process is completed, color-defective observers can distinguish these confusion colors.

Transient Approximation of SAFE-100 Heat Pipe Operation

NASA Technical Reports Server (NTRS)

Bragg-Sitton, Shannon M.; Reid, Robert S.

2005-01-01

Engineers at Los Alamos National Laboratory (LANL) have designed several heat pipe cooled reactor concepts, ranging in power from 15 kWt to 800 kWt, for both surface power systems and nuclear electric propulsion systems. The Safe, Affordable Fission Engine (SAFE) is now being developed in a collaborative effort between LANL and NASA Marshall Space Flight Center (NASA/MSFC). NASA is responsible for fabrication and testing of non-nuclear, electrically heated modules in the Early Flight Fission Test Facility (EFF-TF) at MSFC. In-core heat pipes must be properly thawed as the reactor power starts. Computational models have been developed to assess the expected operation of a specific heat pipe design during start-up, steady state operation, and shutdown. While computationally intensive codes provide complete, detailed analyses of heat pipe thaw, a relatively simple. concise routine can also be applied to approximate the response of a heat pipe to changes in the evaporator heat transfer rate during start-up and power transients (e.g., modification of reactor power level) with reasonably accurate results. This paper describes a simplified model of heat pipe start-up that extends previous work and compares the results to experimental measurements for a SAFE-100 type heat pipe design.

Design of automatic startup and shutdown logic for a Brayton-cycle 2- to 15-kilowatt engine

NASA Technical Reports Server (NTRS)

Vrancik, J. E.; Bainbridge, R. C.

1975-01-01

The NASA Lewis Research Center is conducting a closed-Brayton-cycle power conversion system technology program in which a complete power system (engine) has been designed and demonstrated. This report discusses the design of automatic startup and shutdown logic circuits as a modification to the control system presently used in this demonstration engine. This modification was primarily intended to make starting the engine as simple and safe as possible and to allow the engine to be run unattended. In the modified configuration the engine is started by turning the control console power on and pushing the start button after preheating the gas loop. No other operator action is required to effect a complete startup. Shutdown, if one is required, is also effected by a simple stop button. The automatic startup and shutdown of the engine have been successfully and purposefully demonstrated more than 50 times at the Lewis Research Center during 10,000 hours of unattended operation. The net effect of this modification is an engine that can be safely started and stopped by relatively untrained personnel. The approach lends itself directly to remote unattended operation.

Anatase TiO2 ultrathin nanobelts derived from room-temperature-synthesized titanates for fast and safe lithium storage

PubMed Central

Wen, Wei; Wu, Jin-ming; Jiang, Yin-zhu; Yu, Sheng-lan; Bai, Jun-qiang; Cao, Min-hua; Cui, Jie

2015-01-01

Lithium-ion batteries (LIBs) are promising energy storage devices for portable electronics, electric vehicles, and power-grid applications. It is highly desirable yet challenging to develop a simple and scalable method for constructions of sustainable materials for fast and safe LIBs. Herein, we exploit a novel and scalable route to synthesize ultrathin nanobelts of anatase TiO2, which is resource abundant and is eligible for safe anodes in LIBs. The achieved ultrathin nanobelts demonstrate outstanding performances for lithium storage because of the unique nanoarchitecture and appropriate composition. Unlike conventional alkali-hydrothermal approaches to hydrogen titanates, the present room temperature alkaline-free wet chemistry strategy guarantees the ultrathin thickness for the resultant titanate nanobelts. The anatase TiO2 ultrathin nanobelts were achieved simply by a subsequent calcination in air. The synthesis route is convenient for metal decoration and also for fabricating thin films of one/three dimensional arrays on various substrates at low temperatures, in absence of any seed layers.

Human factors in anaesthesia: lessons from aviation.

PubMed

Toff, N J

2010-07-01

Aviation safety has evolved over more than a century and has achieved remarkable results. Applying some of the lessons learned may help make healthcare safer. From the perspective of an anaesthetic background and some thousands of hours of airline flying, I offer a personal perspective, try to give a sense of the place of human factors in airline operations and some of the current problems, and make some suggestions as to what the NHS and anaesthesia might learn from this. Although many of the ingredients for safe operation are frequently already present in our hospitals, and some individual clinical areas and departments achieve high levels of reliability and safety, I will emphasize my firm belief that we cannot expect improvements in human factors training and awareness to be fully effective in the healthcare setting without the parallel development of a simple and strong safety system across organizations. In the process, we may find that the safe hospital turns out somewhat differently to the safe airline.

Self-Assembled Peptide-Lanthanide Nanoclusters for Safe Tumor Therapy: Overcoming and Utilizing Biological Barriers to Peptide Drug Delivery.

2018-02-27

Developing a sophisticated nanomedicine platform to deliver therapeutics effectively and safely into tumor/cancer cells remains challenging in the field of nanomedicine. In particular, reliable peptide drug delivery systems capable of overcoming biological barriers are still lacking. Here, we developed a simple, rapid, and robust strategy to manufacture nanoclusters of ∼90 nm in diameter that are self-assembled from lanthanide-doped nanoparticles (5 nm), two anticancer peptides with different targets (BIM and PMI), and one cyclic peptide iNGR targeted to cancer cells. The peptide-lanthanide nanoclusters (LDC-PMI-BIM-iNGR) enhanced the resistance of peptide drugs to proteolysis, disassembled in response to reductive conditions that are present in the tumor microenvironment and inhibited cancer cell growth in vitro and in vivo. Notably, LDC-PMI-BIM-iNGR exhibited extremely low systemic toxicity and side effects in vivo. Thus, the peptide-lanthanide nanocluster may serve as an ideal multifunctional platform for safe, targeted, and efficient peptide drug delivery in cancer therapy.

Kutlu, Onur C.; Garcia, Steven; Dissanaike, Sharmila

2012-01-01

INTRODUCTION Tube decompression of the duodenum is an old but underutilized technique known to decrease morbidity and mortality in patients with difficult to manage duodenal injuries. Broad arrays of techniques have been described in the literature and are reviewed, but most are complex procedures not appropriate for the management of an unstable patient. PRESENTATION OF CASE In this paper we describe the technique of tube duodenostomy and the successful application in three cases of large defects (>3 cm) which two of these cases had failed previous repair attempts. The defects were caused by very different etiologies, including blunt trauma, peptic ulcer disease and erosion from cancer. All were finally managed by application of tube duodenostomy with success. DISCUSSION Patients with “difficult to manage duodenum” usually present with hemodynamic instability with hostile abdomen. Complex procedures in an unstable patient are associated with adverse outcomes. In patients with significant comorbidities and instability the damage control principle of trauma surgery is gaining popularity. Tube duodenostomy technique described in this paper fits in well with that principle. CONCLUSION Application of tube duodenostomy instead of a complex procedure in an unstable patient provides an opportunity to stabilize the patient, converting an impending catastrophe to a future scheduled surgery.

Freezing: an underutilized food safety technology?

PubMed

Archer, Douglas L

2004-01-15

Freezing is an ancient technology for preserving foods. Freezing halts the activities of spoilage microorganisms in and on foods and can preserve some microorganisms for long periods of time. Frozen foods have an excellent overall safety record. The few outbreaks of food-borne illness associated with frozen foods indicate that some, but not all human pathogens are killed by commercial freezing processes. Freezing kills microorganisms by physical and chemical effects and possibly through induced genetic changes. Research is needed to better understand the physical and chemical interactions of various food matrices with the microbial cell during freezing and holding at frozen temperatures. The literature suggests that many pathogenic microorganisms may be sublethally injured by freezing, so research should be done to determine how to prevent injured cells from resuscitating and becoming infectious. Studies on the genetics of microbial stress suggest that the induction of resistance to specific stresses may be counteracted by, for example, simple chemicals. Research is needed to better understand how resistance to the lethal effect of freezing is induced in human pathogens and means by which it can be counteracted in specific foods. Through research, it seems possible that freezing may in the future be used to reliably reduce populations of food-borne pathogens as well as to preserve foods.

2010-01-01

To examine family physicians' beliefs and practices about using body mass index (BMI) percentiles to screen for childhood overweight and obesity. Surveys about management of childhood overweight were mailed to 1800 American Academy of Family Physician members in 2006. 729 surveys were returned; 445 were eligible. Most (71%) members were familiar with BMI guidelines; 41% were familiar with American Academy of Family Physician recommendations about overweight. Most (78%) had tools available to calculate BMI; fewer have enough time for overweight screening (55%), and only 45% reported computing BMI percentile at most or every well visit for children older than 2. Having an electronic health record increased BMI screening rates. Family physicians felt prepared to discuss weight, but only 43% believed their counseling was effective and many (55%) lack community or referral services. Most (72%) wanted simple diet and exercise recommendations for patients. Reimbursement for weight-related services is insufficient: 86% say that patients cannot pay for services not covered by insurance. Factor analysis identified clinician self-efficacy, resources, and reimbursement as factors related to calculating BMI percentiles. BMI is underutilized by family physicians. Most believe they should try to prevent overweight and have tools to use BMI, but clinicians have few resources available for treatment, have low self-efficacy, and report inadequate reimbursement.

The goal of pathway analysis is to identify the pathways significantly impacted in a given phenotype. Many current methods are based on algorithms that consider pathways as simple gene lists, dramatically under-utilizing the knowledge that such pathways are meant to capture. During the past few years, a plethora of methods claiming to incorporate various aspects of the pathway topology have been proposed. These topology-based methods, sometimes referred to as “third generation,” have the potential to better model the phenomena described by pathways. Although there is now a large variety of approaches used for this purpose, no review is currently available to offer guidance for potential users and developers. This review covers 22 such topology-based pathway analysis methods published in the last decade. We compare these methods based on: type of pathways analyzed (e.g., signaling or metabolic), input (subset of genes, all genes, fold changes, gene p-values, etc.), mathematical models, pathway scoring approaches, output (one or more pathway scores, p-values, etc.) and implementation (web-based, standalone, etc.). We identify and discuss challenges, arising both in methodology and in pathway representation, including inconsistent terminology, different data formats, lack of meaningful benchmarks, and the lack of tissue and condition specificity.

Specifically, his compiler allows us to convert an arbitrary DSL into Solidity. We focus specifically on converting Domain Specific Languages into Solidity due to their ease of use, and provable properties. By creating a toolchain to compile lightweight domain-specific languages into Ethereum's dominant language, Solidity, we allow non-specialists to effectively develop safe and useful smart contracts. For example lawyers from a certain firm can have a proprietary DSL that codifies basic laws safely converted to Solidity to be securely executed on the blockchain.

2015-08-01

In this paper, septic safe methods of interaction with smart glasses, due to the health care environment applications consideration, are presented. The main focus is on capabilities of an optical, proximity-based gesture sensor and eye-tracker input systems. The design of both interfaces is being adapted to the open smart glasses platform that is being developed under the eGlasses project. Preliminary results obtained from the proximity sensor show that the recognition of different static and dynamic hand gestures is promising. The experiments performed for the eye-tracker module shown the possibility of interaction with simple Graphical User Interface provided by the near-to-eye display. Research leads to the conclusion of attractiveness of collaborative interfaces for interaction with smart glasses.

Five sugar gliders ( Petaurus breviceps ), ranging in age from 3 mo to 3.5 yr of age, and one opossum ( Didelphis virginianus ), age 4.5 mo, presented for elective orchiectomy and scrotal ablation. The LigaSure™ device was safely used for orchiectomy and scrotal ablation in both species. Surgical time with the LigaSure was approximately 4 sec. No grooming of the incision site or self-mutilation was seen in the first 72 hr postoperatively. One sugar glider required postoperative wound care approximately 10 days postoperatively following incision-site grooming by a conspecific. The LigaSure provides a rapid, technologically simple and safe surgical technique for scrotal ablation and orchiectomy in the marsupial patient that minimizes surgical, anesthetic, and recovery times.

Cleft lip and palate is one of the most common craniofacial anomalies of humans. Intraoral impression making is the first clinical step in the fabrication of feeding appliance for infants with oro-nasal communication. It is difficult to control the flow of the impression material in the cleft area and undercuts in a child patient. This clinical report presents a simple and safe impression technique for maxillary impression making in neonates and infants with cleft palate. A gauze piece was used to confine the impression material during functional movements of sucking while impression making in an awake child to avoid the risk of aspiration or swallowing.

Transrectal ultrasound-guided extraction of impacted prostatic urethral calculi: a simple alternative to endoscopy

PubMed Central

2017-01-01

Urethral stones can become impacted in the posterior urethra, typically presenting with varying degrees of acute urinary retention and lower urinary tract symptoms. These are traditionally treated in the inpatient setting, with external urethrotomy or endoscopic push-back of the calculus into the urinary bladder followed by cystolitholapaxy or cystolithotripsy. However, these methods are invasive, involve general anesthesia, and require radiation. In this report, we describe a simple, minimally invasive, and safe alternative technique to visualize and remove impacted prostatic urethral stones under the real-time guidance of transrectal ultrasonography (TRUS). The urologist can accomplish this procedure in the office, avoiding radiation exposure to the patient and hospital admission. PMID:28725602

2005-10-05

Industrial proteins from agriculture of either animal or vegetable origin, including their peptide derivatives, are of great importance, from the qualitative and quantitative point of view, in food formulations (emulsions and foams). A fundamental understanding of the physical, chemical, and functional properties of these proteins is essential if the performance of proteins in foods is to be improved and if underutilized proteins, such as plant proteins (and their hydrolysates and peptides derivatives), are to be increasingly used in traditional and new processed food products (safe, high-quality, health foods with good nutritional value). In this contribution we have determined the main physicochemical characteristics (solubility, composition, and analysis of amino acids) of a sunflower protein isolate (SPI) and its hydrolysates with low (5.62%), medium (23.5%), and high (46.3%) degrees of hydrolysis. The hydrolysates were obtained by enzymatic treatment with Alcalase 2.4 L for DH 5.62 and 23.5% and with Alcalase 2.4 L and Flavorzyme 1000 MG sequentially for DH 46.3%. The protein concentration dependence on surface pressure (surface pressure isotherm), a measure of the surface activity of the products (SPI and its hydrolysates), was obtained by tensiometry. We have observed that the degree of hydrolysis has an effect on solubility, composition, and content of the amino acids of the SPI and its hydrolysates. The superficial activity and the adsorption efficiency were also affected by the degree of hydrolysis.

The study aimed to prospectively investigate whether uterine leiomyoma greater than 10 cm in diameter could be treated with simple ultrasound-guided high-intensity focused ultrasound (USgHIFU) in one-time treatment. A total of 36 patients with 36 symptomatic uterine leiomyoma greater than 10 cm in diameter who underwent simple USgHIFU treatment alone were analysed. Enhanced MRI was performed before and after HIFU treatment, and all patients had follow-up for 6 months after treatment. Symptom severity scores, treatment time, treatment speed, ablation rate, energy effect ratio, uterine leiomyoma regression rate, adverse events, liver and kidney functions, coagulation function and routine blood count were included in the study endpoints. The mean diameter of uterine leiomyoma was 11.2 ± 1.3 cm (10.0-14.3 cm). The median treatment time and treatment speed were 104.0 min (90.0-140.0 min) and 118.8 cm 3  h -1  (86.2-247.1 cm 3  h -1 ), respectively. The ablation rate of uterine leiomyoma was 71.9 ± 20.4% (32.1-100.0%), and the regression rate of uterine leiomyoma was 40.8 ± 7.5% (25.6-59.9%) at 6 months after treatment. The mean symptom severity scores decreased by an average of approximately 8.6 ± 2.3 (5-14) points. There were no significant changes in haemogram and blood chemical indexes of patients, except for the transient elevation of aspartate aminotransferase, total bilirubin and white blood cells after treatment. No serious adverse reactions occurred. According to our preliminary results, simple USgHIFU is a safe and effective single-treatment method of treating uterine leiomyoma greater than 10 cm in diameter and is an almost innocuous alternative therapeutic strategy. Advances in knowledge: The conclusions indicate simple USgHIFU is safe and effective as one-time treatment of uterine leiomyoma greater than 10 cm in diameter, it could be a promising therapeutic strategy.

Underutilized chokeberry (Aronia melanocarpa, Aronia arbutifolia, Aronia prunifolia) accessions are rich sources of anthocyanins, flavonoids, hydroxycinnamic acids, and proanthocyanidins.

PubMed

Taheri, Rod; Connolly, Bryan A; Brand, Mark H; Bolling, Bradley W

2013-09-11

Polyphenols from underutilized black, purple, and red aronia (Aronia melanocarpa, Aronia prunifolia, and Aronia arbutifolia) and 'Viking' (Aronia mitschurinii) berries were characterized. Anthocyanin and nonanthocyanin flavonoids were quantitated by UHPLC-DAD-MS and proanthocyanidins by normal-phase HPLC. On a dry weight basis, anthocyanins were mainly cyanidin-3-galactoside, highest in black aronia (3.4-14.8 mg/g) and lowest in red aronia (0.5-0.8 mg/g) as cyandin-3-galactoside equivalents. Berries from 'Viking' and the red accession UC021 had substantially more proanthocyanidins than the other accessions, with 3.3 and 3.8 mg catechin equiv/g, respectively. Chlorogenic acids and quercetin glycosides were most abundant in purple UC047 berries, at 17.3 and 1.3 mg/g, respectively. In contrast to anthocyanin content, total phenol values were highest in berries from red and purple accessions and attributed to phenolic acid and proanthocyanin content. Thus, red, purple, and black aronia berries are rich sources of polyphenols with various levels of polyphenol classes.

Nutritional and anti-nutritional potential of three accessions of itching bean (Mucuna pruriens (L.) DC var. pruriens): an under-utilized tribal pulse.

PubMed

Kala, Balasubiramanian Kamatchi; Mohan, Veerabahu Ramasamy

2010-08-01

Three accessions of the under-utilized legume itching bean (Mucuna pruriens var. pruriens) were analysed for proximate composition, mineral profiles, vitamins (niacin and ascorbic acid), fatty acid profiles, amino acid profiles of total seed protein, in vitro protein digestibility and certain anti-nutritional factors. All three accessions of M. pruriens var. pruriens contained higher amounts of crude protein and crude lipid when compared with most of the commonly consumed pulses. The fatty acid profiles revealed that the seed lipids contained a higher concentration of palmitic acid and linoleic acids. Amino acid profiles of M. pruriens var. pruriens revealed that the seed protein contained relatively higher levels of certain essential amino acids compared with the FAO/WHO requirement pattern. The investigated seeds are rich in minerals such as potassium, calcium, magnesium, phosphorus, iron and manganese. Anti nutritional substances such as total free phenolics, tannins, 3,4-dihydroxyphenylalanine, phytic acid, hydrogen cyanide, trypsin inhibitor activity, oligosaccharides and phytohaemagglutinating activity were investigated. The anti-nutritional fatty acid, behenic acid, also was detected in the present study.

The Burn Wound Exudate – an under-utilized resource

Widgerow, Alan D; King, Kassandra; Tussardi, Ilaria Tocco; Banyard, Derek A.; Chiang, Ryan; Awad, Antony; Afzel, Hassan; Bhatnager, Shweta; Melkumyan, Satenik; Wirth, Garrett; Evans, Gregory R.D

2014-01-01

Introduction The burn wound exudate represents the burn tissue microenvironment. Extracting information from the exudate relating to cellular components, signaling mediators and protein content can provide much needed data relating to the local tissue damage, depth of the wound and probable systemic complications. This review examines the scientific data extracted from burn wound exudates over the years and proposes new investigations that will provide useful information from this underutilized resource. Method A literature review was conducted using the electronic database PubMed to search for literature pertaining to burn wound or blister fluid analysis. Key words included burn exudate, blister fluid, wound exudate, cytokine burn fluid, subeschar fluid, cytokine burns, serum cytokines. 32 relevant article were examined and 29 selected as relevant to the review. 3 papers were discarded due to questionable methodology or conclusions. The reports were assessed for their affect on management decisions and diagnostics. Furthermore, traditional blood level analysis of these mediators was made to compare the accuracy of blood versus exudate in burn wound management. Extrapolations are made for new possibilities of burn wound exudate analysis. Results Studies pertaining to burn wound exudate, subeschar fluid and blister fluid analyses may have contributed to burn wound management decisions particularly related to escharectomies and early burn wound excision. In addition, information from these studies have the potential to impact on areas such as healing, scarring, burn wound conversion and burn wound depth analysis. Conclusion Burn wound exudate analysis has proven useful in burn wound management decisions. It appears to offer a far more accurate reflection of the burn wound pathophysiology than the traditional blood/serum investigations undertaken in the past. New approaches to diagnostics and treatment efficacy assessment are possible utilizing data from this fluid. Burn wound exudate is a useful, currently under-utilized resource that is likely to take a more prominent role in burn wound management. PMID:24986597

Evidence-based treatments include angiotensin-2 receptor blockers (ARBs), angiotensin-converting enzyme inhibitors (ACE-I), beta-blockers, and aldosterone antagonists. Underutilization of these treatments in heart failure patients were frequently reported, which could lead to increase morbidity and mortality. The aim of this study was to evaluate the utilization of evidence-based treatments and their related factors for elderly patients with chronic heart failure. Methods This is retrospective observational study using the Korean National Health Insurance claims database. We identified prescription of evidence based treatment to elderly patients who had been hospitalized for chronic heart failure between January 1, 2005, and June 30, 2006. Results Among the 28,922 elderly patients with chronic heart failure, beta-blockers were prescribed to 31.5%, and ACE-I or ARBs were prescribed to 54.7% of the total population. Multivariable logistic regression analyses revealed that the prescription from outpatient clinic (prevalent ratio, 4.02, 95% CI 3.31–4.72), specialty of the healthcare providers (prevalent ratio, 1.26, 95% CI, 1.12–1.54), residence in urban (prevalent ratio, 1.37, 95% CI, 1.23–1.52) and admission to tertiary hospital (prevalent ratio, 2.07, 95% CI, 1.85–2.31) were important factors associated with treatment underutilization. Patients not given evidence-based treatment were more likely to experience dementia, reside in rural areas, and have less-specialized healthcare providers and were less likely to have coexisting cardiovascular diseases or concomitant medications than patients in the evidence-based treatment group. Conclusions Healthcare system factors, such as hospital type, healthcare provider factors, such as specialty, and patient factors, such as comorbid cardiovascular disease, systemic disease with concomitant medications, together influence the underutilization of evidence-based pharmacologic treatment for patients with heart failure.

Safe landing is an important part of the planetary exploration mission. Even fine scale terrain hazards (such as rocks, small craters, steep slopes, which would not be accurately detected from orbital reconnaissance) could also pose a serious risk on planetary lander or rover and scientific instruments on-board it. In this paper, a simple geometric approach on planetary landing hazard detection and safe landing site selection is proposed. In order to achieve full implementation of this algorithm, two easy-to-compute metrics are presented for extracting the terrain slope and roughness information. Unlike conventional methods which must do the robust plane fitting and elevation interpolation for DEM generation, in this work, hazards is identified through the processing directly on LiDAR point cloud. For safe landing site selection, a Generalized Voronoi Diagram is constructed. Based on the idea of maximum empty circle, the safest landing site can be determined. In this algorithm, hazards are treated as general polygons, without special simplification (e.g. regarding hazards as discrete circles or ellipses). So using the aforementioned method to process hazards is more conforming to the real planetary exploration scenario. For validating the approach mentioned above, a simulated planetary terrain model was constructed using volcanic ash with rocks in indoor environment. A commercial laser scanner mounted on a rail was used to scan the terrain surface at different hanging positions. The results demonstrate that fairly hazard detection capability and reasonable site selection was obtained compared with conventional method, yet less computational time and less memory usage was consumed. Hence, it is a feasible candidate approach for future precision landing selection on planetary surface.

The green tea catechin, (-)-epigallocatechin-3-O-gallate (EGCG), has gained significant attention as a potent adjuvant to enhance the antitumor efficacy of cisplatin while mitigating its harmful side effects. Herein we report the development of a fail-safe cisplatin nanomedicine constructed with hyaluronic acid-EGCG conjugate for ovarian cancer therapy. A simple mixing of this conjugate and cisplatin induces spontaneous self-assembly of micellar nanocomplexes having a spherical core-shell structure. The surface-exposed hyaluronic acid enables efficient delivery of cisplatin into CD44-overexpressing cancer cells via receptor-mediated endocytosis whereas the internally packed EGCG moieties offer an environment favorable for the encapsulation of cisplatin. In addition, the antioxidant effect of EGCG moieties ensures fail-safe protection against off-target organ toxicity originating from cisplatin-evoked oxidative stress. Pharmacokinetic and biodistribution studies reveal the prolonged blood circulation and preferential tumor accumulation of intravenously administered nanocomplexes. Moreover, the nanocomplexes exhibit superior antitumor efficacy over free cisplatin while displaying no toxicity in both a subcutaneous xenograft model and peritoneal metastatic model of human ovarian cancer. Our findings demonstrate proof of concept for the feasibility of green tea catechin-based micellar nanocomplexes as a safe and effective cisplatin nanomedicine for ovarian cancer treatment.

Evaluation of the sustainability of deep groundwater as an arsenic-safe resource in the Bengal Basin

USGS Publications Warehouse

Michael, H.A.; Voss, C.I.

2008-01-01

Tens of millions of people in the Bengal Basin region of Bangladesh and India drink groundwater containing unsafe concentrations of arsenic. This high-arsenic groundwater is produced from shallow (150 m where groundwater arsenic concentrations are nearly uniformly low, and many more wells are needed, however, the sustainability of deep, arsenic-safe ground-water has not been previously assessed. Deeper pumping could induce downward migration of dissolved arsenic, permanently destroying the deep resource. Here, it is shown, through quantitative, large-scale hydrogeologic analysis and simulation of the entire basin, that the deeper part of the aquifer system may provide a sustainable source of arsenic-safe water if its utilization is limited to domestic supply. Simulations provide two explanations for this result: deep domestic pumping only slightly perturbs the deep groundwater flow system, and substantial shallow pumping for irrigation forms a hydraulic barrier that protects deeper resources from shallow arsenic sources. Additional analysis indicates that this simple management approach could provide arsenic-safe drinking water to >90% of the arsenic-impacted region over a 1,000-year timescale. This insight may assist water-resources managers in alleviating one of the world's largest groundwater contamination problems. ?? 2008 by The National Academy of Sciences of the USA.

Centrifuge advances using HTS magnetic bearings

Passive magnetic bearings are of increasing technical interest. We performed experiments with centrifugal rotors to analyze gyroscopic forces in terms imbalance, rotor elasticity and damping. Centrifuge rotors need to be operated soft and stable without whirling the sediments. In order to evaluate optimal parameters critical and resonance behaviors are investigated. Eccentricities up 2 mm are safely passed by accelerating test wheels. In a simple model we describe the effect of passing critical rotational speeds. Measurements of bearing properties and wheel performance are presented. We have constructed a first prototype centrifuge designed with a HTS double bearing which operates a titanium rotor safely up to 30 000 rpm. A 15 W Stirling cooler serves cryogenics of the YBCO stators. From the experiments design guidelines for centrifugal applications with HTS bearings are given.

Prone positioning in the patient who has acute respiratory distress syndrome: the art and science.

2004-09-01

Acute respiratory distress syndrome (ARDS) remains a significant contributor to the morbidity and mortality of patients in the ICU. A variety of treatments are used to support the lung of the patient who has ARDS and improve gas exchange during the acute injury phase. It seems, however, that the simple, safe, and noninvasive act of prone positioning of the critically ill patient who has ARDS may improve gas exchange while preventing potential complications of high positive end-expiratory pressure, volutrauma, and oxygen toxicity. This article provides the critical care nurse with the physiologic rationale for use of the prone position, indications and contraindications for use, safe strategies for prone positioning, and care techniques and monitoring methods of the patient who is in the prone position.

Unsafe abortion is affecting a lot, in health, socio-economic and health care cost of many countries. Despite invention of simple technology and scientifically approved safe abortion methods, women and girls are still using unsafe abortion practices. Since 2002, Nepal has achieved remarkable progress in developing policies, guidelines, task shifting, training human resources and increasing access to services. However, more than half of abortion in Nepal are performed clandestinely by untrained or unapproved providers or induced by pregnant woman herself. Knowledge on legalization and availability of safe abortion service among women is still very poor. Stigma on abortion still persists among community people, service providers, managers, and policy makers. Access to safe abortion, especially in remote and rural areas, is still far behind as compared to their peers from urban areas. The existing law is not revised in the spirit of current Constitution of Nepal and rights-based approach. The existence of abortion stigma and the shifting of the government structure from unitary system to federalism in absence of a complete clarity on how the safe abortion service gets integrated into the local government structure might create challenge to sustain existing developments. There is, therefore, a need for all stakeholders to make a lot of efforts and allocate adequate resources to sustain current achievements and ensure improvements in creating a supportive social environment for women and girls so that they will be able to make informed decisions and access to safe abortion service in any circumstances.

The SAD (safety and arming device) is an indispensable fuse component that ensures safe and reliable performance during the use of ammunition. Because the application of electronic devices for smart munitions is increasing, miniaturization of the SAD has become one of the key issues for next-generation artillery fuses. Based on MEMS technology, various types of miniaturized SADs have been proposed and fabricated. However, none of them have been reported to have been used in actual munitions due to their lack of high impact endurance and complicated explosive train arrangements. In this research, a new MEMS SAD using a ball driven mechanism, is successfully demonstrated based on a UV LIGA (lithography, electroplating and molding) process. Unlike other MEMS SADs, both high impact endurance and simple structure were achieved by using a ball driven mechanism. The simple structural design also simplified the fabrication process and increased the processing yield. The ball driven type MEMS SAD performed successfully under the desired safe and arming conditions of a spin test and showed fine agreement with the FEM simulation result, conducted prior to its fabrication. A field test was also performed with a grenade launcher to evaluate the SAD performance in the firing environment. All 30 of the grenade samples equipped with the proposed MEMS SAD operated successfully under the high-G setback condition.

To conduct a proof-of-concept study to determine the potential utility of a novel, adjustable single-visit, disposable device to facilitate rapid adult circumcision. Prospective pilot trial of a novel surgical device. Tertiary care Veterans Administration medical center. Five adult males. Circumcisions performed by junior trainees using an adjustable, single-size surgical-assist device constructed by the University of Washington Applied Physics Laboratory. The attending surgeon and trainees completed standardized forms after each procedure to assess technical problems and ease of use. Follow-up visits were scheduled to evaluate adverse events, postoperative pain, cosmetic outcomes, and participant satisfaction at 3, 8, 30, and 90 days postoperatively. The average operative time was 16.4 minutes. All cases were performed with local anesthesia, and no case required electrocautery or conversion to standard surgery. At the postoperative day 3 visit, all subjects were happy with their results and would recommend the procedure to another patient. One participant had a minor wound separation noted at the 30-day visit that resolved during follow-up. There were no wound infections, hematomas, or other adverse events. This proof-of-study suggests that the Simple Circumcision Device may facilitate delivery of safe adult male circumcision services. Copyright © 2014 American Society for Reproductive Medicine.

Acute lower gastrointestinal bleeding is a common reason for emergency hospital admission, and identification of patients at low risk of harm, who are therefore suitable for outpatient investigation, is a clinical and research priority. We aimed to develop and externally validate a simple risk score to identify patients with lower gastrointestinal bleeding who could safely avoid hospital admission. We undertook model development with data from the National Comparative Audit of Lower Gastrointestinal Bleeding from 143 hospitals in the UK in 2015. Multivariable logistic regression modelling was used to identify predictors of safe discharge, defined as the absence of rebleeding, blood transfusion, therapeutic intervention, 28 day readmission, or death. The model was converted into a simplified risk scoring system and was externally validated in 288 patients admitted with lower gastrointestinal bleeding (184 safely discharged) from two UK hospitals (Charing Cross Hospital, London, and Hammersmith Hospital, London) that had not contributed data to the development cohort. We calculated C statistics for the new model and did a comparative assessment with six previously developed risk scores. Of 2336 prospectively identified admissions in the development cohort, 1599 (68%) were safely discharged. Age, sex, previous admission for lower gastrointestinal bleeding, rectal examination findings, heart rate, systolic blood pressure, and haemoglobin concentration strongly discriminated safe discharge in the development cohort (C statistic 0·84, 95% CI 0·82-0·86) and in the validation cohort (0·79, 0·73-0·84). Calibration plots showed the new risk score to have good calibration in the validation cohort. The score was better than the Rockall, Blatchford, Strate, BLEED, AIMS65, and NOBLADS scores in predicting safe discharge. A score of 8 or less predicts a 95% probability of safe discharge. We developed and validated a novel clinical prediction model with good discriminative performance to identify patients with lower gastrointestinal bleeding who are suitable for safe outpatient management, which has important economic and resource implications.

2016-02-01

Percutaneous treatments for trigeminal neuralgia are safe, simple, and effective for achieving good pain control. Procedural risks could be minimized by using noninvasive imaging techniques to improve the placement of the radiofrequency thermocoagulation probe into the trigeminal ganglion. Positioning of a probe is crucial to maximize pain relief and to minimize unwanted side effects, such as denervation in unaffected areas. This investigation examined the use of laser speckle imaging during probe placement in an animal model. This preclinical safety study used nonhuman primates, Macaca nemestrina (pigtail monkeys), to examine whether real-time imaging of blood flow in the face during the positioning of a coagulation probe could monitor the location and guide the positioning of the probe within the trigeminal ganglion. Data from 6 experiments in 3 pigtail monkeys support the hypothesis that laser imaging is safe and improves the accuracy of probe placement. Noninvasive laser speckle imaging can be performed safely in nonhuman primates. Because improved probe placement may reduce morbidity associated with percutaneous rhizotomies, efficacy trials of laser speckle imaging should be conducted in humans.

Airway management through submental derivation: a safe and easily reproduced alternative for patients with complex facial trauma

PubMed Central

2018-01-01

Objectives Airway management in patients with panfacial trauma is complicated. In addition to involving facial lesions, such trauma compromises the airway, and the use of intermaxillary fixation makes it difficult to secure ventilation by usual approaches (nasotracheal or endotracheal intubation). Submental airway derivation is an alternative to tracheostomy and nasotracheal intubation, allowing a permeable airway with minimal complications in complex patients. Materials and Methods This is a descriptive, retrospective study based on a review of medical records of all patients with facial trauma from January 2003 to May 2015. In total, 31 patients with complex factures requiring submental airway derivation were included. No complications such as bleeding, infection, vascular, glandular, or nervous lesions were presented in any of the patients. Results The use of submental airway derivation is a simple, safe, and easy method to ensure airway management. Moreover, it allows an easier reconstruction. Conclusion Based on these results, we concluded that, if the relevant steps are followed, the use of submental intubation in the treatment of patients with complex facial trauma is a safe and effective option.

With increasing production of red mud, the environmental problems caused by it are increasingly serious, and thus the integrated treatment of red mud is imminent. This article provides an overview of the composition and the basic characteristics of red mud. The research progress of safe stockpiling and comprehensive utilization of red mud is summarized. The safe stockpiling of red mud can be divided into two aspects: the design and safe operation of the stocking yard. The comprehensive utilization of red mud can be further divided into three aspects: the effective recycling of components, resource utilization and application in the field of environmental protection. This paper points out that the main focus of previous studies on red mud stockpiling is cost reproduction and land tenure. The recovery of resources from red mud has a high value-added, but low level industrialization. The use of red mud as a building material and filler material is the most effective way to reduce the stockpiling of red mud. Red mud used for environmental remediation materials is a new hotspot and worth promoting for its simple processing and low cost.

A simple and rapid gas chromatography with flame photometric detector (GC-FPD) determination method was developed to detect residue levels and investigate the dissipation pattern and safe use of fenitrothion in tomatoes. A modified quick, easy, cheap, effective, rugged, and safe (QuEChERS) using an ethyl acetate-based extraction, followed by a dispersive solid-phase extraction (d-SPE) with primary-secondary amine (PSA) and graphite carbon black (GCB) for clean up, was applied prior to GC-FPD analysis. The method showed satisfactory linearity, recovery and precision. The limits of detection (LOD) and quantification (LOQ) were 0.005 and 0.01mg/kg, respectively. The residue levels of fenitrothion were best described by first order kinetics with a half-life of 2.2days in tomatoes. The potential health risks posed by fenitrothion were not significant, based on supervised residue trial data. The current findings could provide guidance for safe and reasonable use of fenitrothion in tomatoes and prevent health problems to consumers. Copyright © 2017 Elsevier Ltd. All rights reserved.

A low-voltage (mV) electronically triggered spot welding system for fabricating fine thermocouples and thin sheets used in high-temperature characterization of materials' properties is suggested. The system is based on the capacitance discharge method with a timed trigger for obtaining reliable and consistent welds. In contrast to existing techniques based on employing high voltage DC supplies for charging the capacitor or supplies with positive and negative rails, this method uses a simple, standard dual power supply available at most of the physical laboratories or can be acquired at a low cost. In addition, an efficient and simple method of fabricating non-sticking electrodes that do not contaminate the weld area is suggested and implemented.

To introduce and evaluate the safety of a novel dual-sided electrosurgery handpiece design for simultaneous tissue cutting and coagulation. We designed a prototype double-sided handpiece allowing automatic switching between two electrodes with a simple handpiece flip. The concept of the system as a surgical instrument was assessed by an animal experiment. The skin of 15 Wistar albino white rats could be successfully incised and coagulated using both ends of the handpiece, thereby confirming the prospects and clinical applications of the system. The dual-sided electrosurgery handpiece is a simple and safe alternative to the traditional electrosurgery pencil, allowing the simultaneous use of two electrodes without the hassle of frequent electrode replacement.

In this paper, we present a simple method to analyze the injection efficiency of the photodiode interface circuit under fast shuttering conditions for active Imaging applications. This simple model has been inspired from the companion model for reactive elements largely used in CAD. In this paper, we demonstrate that traditional CTIA photodiode interface is not adequate for active imaging where fast and precise shuttering operation is necessary. Afterwards we present a direct amplification based photodiode interface which can provide an accurate and fast shuttering operation on photodiode. These considerations have been used in NIT's newly developed ROIC and corresponding SWIR sensors both in VGA 15um pitch (NSC1201) and also in QVGA 25um pitch (NSC1401).
