    Laparoscopic pyloromyotomy has gained popularity in the treatment of hypertrophic pyloric stenosis. This is the first case report of carbon dioxide embolism during laparoscopic pyloromyotomy. We describe a case of carbon dioxide embolism in a 3-week-old neonate during laparoscopic pyloromyotomy by injection of carbon dioxide into a patent umbilical vein. The diagnosis of carbon dioxide embolism was made on the basis of the abrupt decrease in end-tidal CO(2), sudden decreased Spo(2), hypotension, and cyanosis. Portable x-ray with the clinical presentation was sufficient for a diagnosis of carbon dioxide embolism. Treatment included termination of CO(2) insufflation, placing the patient in Durant's position, and adequate resuscitation as necessary. Despite the fact that the insufflation pressure was in the recommended range, a carbon dioxide embolism was thought to be caused by injection of carbon dioxide into a patent umbilical vein. Although laparoscopic pyloromyotomy has demonstrated to be a safe and effective procedure, this is a serious and rare complication causing prolonged length of stay and skewed hospital charges.

    Background: Atropine has been used as a successful primary medical treatment for hypertrophic pyloric stenosis. Several authors have reported a higher rate of incomplete pyloromyotomy with the laparoscopic approach compared to open. In this study, we evaluated the use of atropine as a medical treatment for infants with emesis persisting greater than 48 hours after a laparoscopic pyloromyotomy. Materials and Methods: We performed a retrospective chart review of infants receiving a laparoscopic pyloromyotomy between November 1998 and November 2012. Infants with emesis that persisted beyond 48 hours postoperatively were given 0.01mg/kg of oral atropine 10 minutes prior to feeding. Infants remained inpatient until they tolerated two consecutive feedings without emesis. Results: 965 patients underwent laparoscopic pyloromyotomy; 816 (84.6%) male and 149 (15.4%) female. Twenty-four (2.5%) received oral atropine. The mean length of stay for patients who received atropine was 5.6 ± 2.6 days, an average of 3 additional days. They were discharged home with a one-month supply of oral atropine. Follow up evaluation did not reveal any complications from receiving atropine. The median follow up was 21 days. None returned to the operating room for incomplete pyloromyotomy. There were 17 (1.8%) operative complications in our series; 9 mucosal perforations, 2 duodenal perforations, and 6 conversions to open for equipment failure or poor exposure. There were 4 (0.4%) post-operative complications: 2 episodes of apnea requiring reintubation and 2 incisional hernias that required a second operation. There were no deaths. Conclusion: Oral atropine is a viable treatment for persistent emesis after a pyloromyotomy and reduces the need for a second operation due to incomplete pyloromyotomy. PMID:28083488

    No studies have investigated the cosmetic outcome of current approaches to pyloromyotomy in infants with hypertrophic pyloric stenosis. The purpose of this study was to evaluate the final appearance of the scar in patients undergoing circumumbilical pyloromyotomy. During a 16-year period, 86 infants underwent circumumbilical pyloromyotomy at our institution. A detailed questionnaire was created to document the family members' perceptions of the esthetic appearance of the scar. Data were collected by telephone interview and at clinic visit. In addition, cosmesis was assessed by 5 staff members who scored blindly the esthetic outcome of the scars with comparative photographs, using a categorical scale. Fifty-seven families were tracked by telephone contact. In the family questionnaire, 100% of families reported an excellent or good scar. Of these, forty-one (72%) were available for cosmetic assessment. Follow-up ranged between 5 months and 15 years (mean, 6 years). The panel members ranked the scar, on average, as excellent or good for 90% of the patients. No assessor stated that a scar was unacceptable. Intra- and interobserver agreement was 0.72 and 0.78, respectively. Overall satisfaction with the cosmetic outcome of circumumbilical pyloromyotomy is very high.

    We conducted a prospective feasibility study to evaluate the value of microlaparoscopic pyloromyotomy for hypertrophic pyloric stenosis in infants. All data were prospectively collected, and the procedures were documented by video recording. Patients were selected based on the availability of the equipment and consultant surgeons experienced in microlaparoscopy. Microlaparoscopic (exclusive use of 2-mm instruments and small-diameter scopes, 1.7-1.9 mm in diameter) pyloromyotomy was performed. All procedures were done under general anesthesia with endotracheal intubation. This study includes 21 infants, 14 boys and 7 girls (aged 3-12 weeks, average 4.8 weeks). Weight at admission averaged 4,100 g (range 3,200-5,500 g). Mean wall thickness of pyloric muscle measured by ultrasound was 4.5 mm (range 3.8-7.8 mm). Average operative time was 13 min for the consultant surgeon. Full feeding was attained on the first postoperative day in 16 infants. Postoperative length of stay averaged 87 h. Eighteen infants were re-examined to assess cosmesis. Despite the limited patient population included in this study, we conclude that use of microlaparoscopic pyloromyotomy for hypertrophic pyloric stenosis is safe and feasible, and the technique provides minimal access trauma and superior cosmesis.

    Several surgical treatments exist for treatment of gastroparesis, including gastric electrical stimulation, pyloroplasty, and gastrectomy. Division of the pylorus by means of endoscopy, Per-Oral Pyloromyotomy (POP), is a newer, endoluminal therapy that may offer a less invasive, interventional treatment option. We describe and present a video of our step by step technique for POP using a lesser curvature approach. The following are technical steps to complete the POP procedure from the lesser curve approach. In our experience, these methods provide promising initial results with low operative risks, although long-term outcomes remain to be determined.

    Ruiz Volcano, Colombia (4.88°N, 75.32°W). All times are local (= GMT -5 hours).An explosive eruption on November 13, 1985, melted ice and snow in the summit area, generating lahars that flowed tens of kilometers down flank river valleys, killing more than 20,000 people. This is history's fourth largest single-eruption death toll, behind only Tambora in 1815 (92,000), Krakatau in 1883 (36,000), and Mount Pelée in May 1902 (28,000). The following briefly summarizes the very preliminary and inevitably conflicting information that had been received by press time.

    2010-03-01

    We studied the feasibility of using methylene blue (MB) as a marker to detect mucosal perforations during laparoscopic pyloromyotomy using in vitro and in vivo animal models. MB was initially tested in pig stomachs in vitro. Information gathered from these experiments was then used to test the marker during experimental live piglet laparoscopic surgery. MB stained the gastric mucosa blue; this tint could be seen through the intact mucosal layer exposed via myotomy. Dye extravasation was seen during laparoscopic surgery with mucosal perforations of 1.2 mm and greater with or without air insufflation of the stomach. Air extravasation was seen with perforations of 2.0 mm and greater. Full strength 1% MB dye instilled into the gastric lumen can potentially be used as a marker for detection of mucosal perforations of 1.2 mm or greater during laparoscopic pyloromyotomy.

    We conducted a prospective, randomized trial comparing protocol to ad libitum (ad lib) feeding after laparoscopic pyloromyotomy. Infants undergoing laparoscopic pyloromyotomy were randomized to protocol versus ad lib feeding strategies. The protocol started with Pedialyte® two hours post-operative. This was repeated by another round of Pedialyte®, then two rounds of half-strength formula or breast milk, followed by two rounds of full strength formula or breast milk, followed by the home feeding regimen, at which time the patient was discharged if feeding well. The ad lib group was allowed formula or breast milk two hours after the operation and considered for discharge after tolerating three consecutive feeds. The primary outcome variable was the length of postoperative hospitalization. One hundred fifty infants were enrolled between January 2010 and December 2011. There were no differences in patient characteristics at presentation. While the ad lib group reached goal feeds sooner than the protocol group, this did not translate into a difference in duration of postoperative hospitalization. There were more patients with emesis in the ad lib group after goal feeding was reached, but no difference in readmissions. Ad lib feeding allows patients to reach goal feeds more rapidly than protocol feeding following laparoscopic pyloromyotomy. However, this goal is usually reached beyond discharge hours, resulting in a similar duration of hospitalization. © 2014.

  13. Should general surgery residents be taught laparoscopic pyloromyotomies? An ethical perspective.

    2014-01-01

    The authors examine the ethical implications of teaching general surgery residents laparoscopic pyloromyotomy. Using the authors' previously presented ethical framework, and examining survey data of pediatric surgeons in the United States and Canada, a rigorous ethical argument is constructed to examine the question: should general surgery residents be taught laparoscopic pyloromyotomies? A survey was constructed that contained 24 multiple-choice questions. The survey included questions pertaining to surgeon demographics, if pyloromyotomy was taught to general surgery and pediatric surgery residents, and management of complications encountered during pyloromyotomy. A total of 889 members of the American Pediatric Surgical Association and Canadian Association of Paediatric Surgeons were asked to participate. The response rate was 45% (401/889). The data were analyzed within the ethical model to address the question of whether general surgery residents should be taught laparoscopic pyloromyotomies. From an ethical perspective, appealing to the ethical model of a physician as a fiduciary, the answer is no. We previously proposed an ethical model based on 2 fundamental ethical principles: the ethical concept of the physician as a fiduciary and the contractarian model of ethics. The fiduciary physician practices medicine competently with the patient’s best interests in mind. The role of a fiduciary professional imposes ethical standards on all physicians, at the core of which is the virtue of integrity, which requires the physician to practice medicine to standards of intellectual and moral excellence. The American College of Surgeons recognizes the need for current and future surgeons to understand professionalism, which is one of the 6 core competencies specified by the Accreditation Council for Graduate Medical Education. Contracts are models of negotiation and ethically permissible compromise. Negotiated assent or consent is the core concept of contractarian

    The results of a 3 month preliminary design and analysis effort is presented. The configuration that emerged consists of a very stiff deployable truss structure with an overall triangular cross section having universal modules attached at the apexes. Sufficient analysis was performed to show feasibility of the configuration. An evaluation of the structure shows that desirable attributes of the configuration are: (1) the solar cells, radiators, and antennas will be mounted to stiff structure to minimize control problems during orbit maintenance and correction, docking, and attitude control; (2) large flat areas are available for mounting and servicing of equipment; (3) Large mass items can be mounted near the center of gravity of the system to minimize gravity gradient torques; (4) the trusses are lightweight structures and can be transported into orbit in one Shuttle flight; (5) the trusses are expandable and will require a minimum of EVA; and (6) the modules are anticipated to be structurally identical except for internal equipment to minimize cost.

The information presented in this report will be used in subsequent stages of the ecological risk assessment to refine the conceptual site model, assist in the selection of contaminants of concern, identify potential ecological receptors, and evaluate trophic relationships and other exposure pathways. The unit reconnaissance survey was conducted in accordance with Specification No. E-18272, Rev. 1 dated August 5, 1993, and the Draft {open_quotes}Ecological Risk Assessment Program Plan for Evaluation of Waste Sites on the Savannah River Site{close_quotes}. The objectives of the site reconnaissance were to: Assess the general characteristics of on-unit biological communities including mammals, birds, reptiles, amphibians, and any aquatic communities present. Determine the location, extent, and characteristics of on-unit ecological resources, such as forested areas and wetlands, that could serve as important wildlife habitat or provide other ecological functions. Identify any overt effects of contamination on biological communities. The field investigations included mapping and describing all wetland and terrestrial habitats; recording wildlife observations of birds, mammals, and reptiles; and investigating ecological resources in nearby downgradient and downstream areas which could be affected by mobile contaminants or future remedial actions. In preparation for the field investigation, existing unit information including aerial photographs and reports were reviewed to help identify and describe ecological resources at the waste unit.

    The Melter Performance Assessment activity, a component of the Pacific Northwest Laboratory`s (PNL) Vitrification Technology Development (PVTD) effort, was designed to determine the impact of noble metals on the operational life of the reference Hanford Waste Vitrification Plant (HWVP) melter. The melter performance assessment consisted of several activities, including a literature review of all work done with noble metals in glass, gradient furnace testing to study the behavior of noble metals during the melting process, research-scale and engineering-scale melter testing to evaluate effects of noble metals on melter operation, and computer modeling that used the experimental data to predict effects of noble metals on the full-scale melter. Feed used in these tests simulated neutralized current acid waste (NCAW) feed. This report summarizes the results of the melter performance assessment and predicts the lifetime of the HWVP melter. It should be noted that this work was conducted before the recent Tri-Party Agreement changes, so the reference melter referred to here is the Defense Waste Processing Facility (DWPF) melter design.

    Hypertrophic pyloric stenosis is a relatively common affection of gastrointestinal tract in childhood that results in symptoms, such as projectile vomiting and metabolic disorders that imply a high risk of aspiration during anesthetic induction. In this way, the carrying out of a technique with general anesthesia and intravenous rapid sequence induction, preoxygenation and cricoid pressure are recommended. After the correction of systemic metabolic alkalosis and pH normalization, cerebrospinal fluid can keep a state of metabolic alkalosis. This circumstance, in addition to the residual effect of neuromuscular blocking agents, inhalant anesthetics and opioids could increase the risk of postoperative apnea after a general anesthesia. We present the successful management in 3 neonates in those a pyloromyotomy was carried out because they had presented congenital hypertrophic pyloric stenosis. This procedure was done under general anesthesia with orotracheal intubation and rapid sequence induction. Then, ultrasound-guided paravertebral block was performed as analgesic method without the need for administrating opioids within intraoperative period and keeping an appropriate analgesic level. Local anesthesia has demonstrated to be safe and effective in pediatric practice. We consider the ultrasound-guided paravertebral block with one dose as a possible alternative for other local techniques described, avoiding the use of opioids and neuromuscular blocking agents during general anesthesia, and reducing the risk of central apnea within postoperative period.

    Background Colombia began official surveillance for Zika virus disease (ZVD) in August 2015. In October 2015, an outbreak of ZVD was declared after laboratory-confirmed disease was identified in nine patients. Methods Using the national population-based surveillance system, we assessed patients with clinical symptoms of ZVD from August 9, 2015, to April 2, 2016. Laboratory test results and pregnancy outcomes were evaluated for a subgroup of pregnant women. Concurrently, we investigated reports of microcephaly for evidence of congenital ZVD. Results By April 2, 2016, there were 65,726 cases of ZVD reported in Colombia, of which 2485 (4%) were confirmed by means of reverse-transcriptase-polymerase-chain-reaction (RT-PCR) assay. The overall reported incidence of ZVD among female patients was twice that in male patients. A total of 11,944 pregnant women with ZVD were reported in Colombia, with 1484 (12%) of these cases confirmed on RT-PCR assay. In a subgroup of 1850 pregnant women, more than 90% of women who were reportedly infected during the third trimester had given birth, and no infants with apparent abnormalities, including microcephaly, have been identified. A majority of the women who contracted ZVD in the first or second trimester were still pregnant at the time of this report. Among the cases of microcephaly investigated from January 2016 through April 2016, four patients had laboratory evidence of congenital ZVD; all were born to asymptomatic mothers who were not included in the ZVD surveillance system. Conclusions Preliminary surveillance data in Colombia suggest that maternal infection with the Zika virus during the third trimester of pregnancy is not linked to structural abnormalities in the fetus. However, the monitoring of the effect of ZVD on pregnant women in Colombia is ongoing. (Funded by Colombian Instituto Nacional de Salud and the Centers for Disease Control and Prevention.).

  13. NSLS-II Preliminary Design Report

    SciTech Connect

    Dierker, S.

    2007-11-01

    Following the CD0 approval of the National Synchrotron Light Source II (NSLS-II) during August 2005, Brookhaven National Laboratory prepared a conceptual design for a worldclass user facility for scientific research using synchrotron radiation. DOE SC review of the preliminary baseline in December 2006 led to the subsequent CD1 approval (approval of alternative selection and cost range). This report is the documentation of the preliminary design work for the NSLS-II facility. The preliminary design of the Accelerator Systems (Part 1) was developed mostly based of the Conceptual Design Report, except for the Booster design, which was changed from in-storage-ring tunnel configuration to in external- tunnel configuration. The design of beamlines (Part 2) is based on designs developed by engineering firms in accordance with the specification provided by the Project. The conventional facility design (Part 3) is the Title 1 preliminary design by the AE firm that met the NSLS-II requirements. Last and very important, Part 4 documents the ES&H design and considerations related to this preliminary design. The NSLS-II performance goals are motivated by the recognition that major advances in many important technology problems will require scientific breakthroughs in developing new materials with advanced properties. Achieving this will require the development of new tools that will enable the characterization of the atomic and electronic structure, chemical composition, and magnetic properties of materials, at nanoscale resolution. These tools must be nondestructive, to image and characterize buried structures and interfaces, and they must operate in a wide range of temperatures and harsh environments. The NSLS-II facility will provide ultra high brightness and flux and exceptional beam stability. It will also provide advanced insertion devices, optics, detectors, and robotics, and a suite of scientific instruments designed to maximize the scientific output of the facility

  14. Analytical Chemistry Core Capability Assessment - Preliminary Report

    SciTech Connect

    Barr, Mary E.; Farish, Thomas J.

    2012-05-16

    The concept of 'core capability' can be nebulous one. Even at a fairly specific level, where core capability equals maintaining essential services, it is highly dependent upon the perspective of the requestor. Samples are submitted to analytical services because the requesters do not have the capability to conduct adequate analyses themselves. Some requests are for general chemical information in support of R and D, process control, or process improvement. Many analyses, however, are part of a product certification package and must comply with higher-level customer quality assurance requirements. So which services are essential to that customer - just those for product certification? Does the customer also (indirectly) need services that support process control and improvement? And what is the timeframe? Capability is often expressed in terms of the currently utilized procedures, and most programmatic customers can only plan a few years out, at best. But should core capability consider the long term where new technologies, aging facilities, and personnel replacements must be considered? These questions, and a multitude of others, explain why attempts to gain long-term consensus on the definition of core capability have consistently failed. This preliminary report will not try to define core capability for any specific program or set of programs. Instead, it will try to address the underlying concerns that drive the desire to determine core capability. Essentially, programmatic customers want to be able to call upon analytical chemistry services to provide all the assays they need, and they don't want to pay for analytical chemistry services they don't currently use (or use infrequently). This report will focus on explaining how the current analytical capabilities and methods evolved to serve a variety of needs with a focus on why some analytes have multiple analytical techniques, and what determines the infrastructure for these analyses. This information will be

    Lowry, Peter P.; Wagner, Katie A.

    2015-08-31

    A preliminary hazard assessment was completed during February 2015 to evaluate the conceptual design of the modular hydrothermal liquefaction treatment system. The hazard assessment was performed in 2 stages. An initial assessment utilizing Hazard Identification and Preliminary Hazards Analysis (PHA) techniques identified areas with significant or unique hazards (process safety-related hazards) that fall outside of the normal operating envelope of PNNL and warranted additional analysis. The subsequent assessment was based on a qualitative What-If analysis. This analysis was augmented, as necessary, by additional quantitative analysis for scenarios involving a release of hazardous material or energy with the potential for affecting the public.

    In October 2001, Nanashakon, a council composed of seven psychiatry-related organizations in Japan, decided to launch an investigation into forensic psychiatry in Japan, and established a working team (WT) for this purpose. From its establishment to March 2004, the WT performed surveys and analyses of the current situation of preliminary reports by psychiatric experts (preliminary reports) and of psychiatric practice in correctional facilities. Based on the results, the WT has presented proposals including guidelines for preliminary reports. In January 2002, the WT conducted an awareness survey on the status quo of testimony by psychiatric experts and forensic psychiatry, targeting the members of the Japanese Society of Psychiatry and Neurology, and obtained 666 replies. The survey revealed various critical opinions such as skepticism over the current punishment imposed on criminal patients with mental disorders. In February 2002, the WT obtained data on preliminary reports (2,042 cases) compiled prior to prosecution in FY2000 from the Japanese Ministry of Justice. Reviewing the details and differences between the evaluation by psychiatrists and the decision by public prosecutors, the WT pointed out the ambiguity of criteria used for the evaluation of competency of weak-minded persons and the criteria for criminal punishment. Around the same time, the WT was also asked by a news agency to analyze the preliminary reports of 50 district public prosecutor offices. The results revealed marked regional differences in the operation of the preliminary evaluation system for competency. In January 2003, the WT collected 146 preliminary reports from around the country for comparison and review, and again found conspicuous individual and regional discrepancies in the format and content. Based on these results, the WT conducted a hearing of 41 expert opinions on preliminary reports, and in January 2004, proposed guidelines outlining a format model of preliminary reports, and a

    2013-08-01

    Vulvodynia (vulvar pain syndrome) is a chronic multifactorial disease affecting almost 13 million women in the USA and can lead to morbidity and a reduced quality of life. We hypothesize that an initial microbiological insult in the vagina causes modifications in the biological vaginal milieu and/or an alteration on the lactobacilli flora. The vaginal milieu responds to the insult by developing an inflammatory reaction with abnormal cytokine production. These hypotheses were tested quantifying vaginal lactobacillus and cytokines, in patients with vulvodynia compared to matched healthy controls. Our preliminary data suggest a vaginal flora alteration and an immunological response involving Candida in patients with vulvodynia. Ongoing studies will assist us to clarify these findings.

    In collaboration with the Pyramid Lake Paiute Tribe (PLPT), the University of Nevada, Reno (UNR) and Optim re-processed, or collected and processed, over 24 miles of 2d seismic-reflection data near the northwest corner of Pyramid Lake, Nevada. The network of 2d land surveys achieved a near-3d density at the Astor Pass geothermal prospect that the PLPT drilled during Nov. 2010 to Feb. 2011. The Bureau of Indian Affairs funded additional seismic work around the Lake, and an extensive, detailed single-channel marine survey producing more than 300 miles of section, imaging more than 120 ft below the Lake bottom. Optim’s land data collection utilized multiple heavy vibrators and recorded over 200 channels live, providing a state-of-the-art reflection-refraction data set. After advanced seismic analysis including first-arrival velocity optimization and prestack depth migration, the 2d sections show clear fault-plane reflections, in some areas as deep as 4000 ft, tying to distinct terminations of the mostly volcanic stratigraphy. Some lines achieved velocity control to 3000 ft depth; all lines show reflections and terminations to 5000 ft depth. Three separate sets of normal faults appear in an initial interpretation of fault reflections and stratigraphic terminations, after loading the data into the OpendTect 3d seismic visualization system. Each preliminary fault set includes a continuous trace more than 3000 ft long, and a swarm of short fault strands. The three preliminary normal-fault sets strike northerly with westward dip, northwesterly with northeast dip, and easterly with north dip. An intersection of all three fault systems documented in the seismic sections at the end of Phase I helped to locate the APS-2 and APS-3 slimholes. The seismic sections do not show the faults connected to the Astor Pass tufa spire, suggesting that we have imaged mostly Tertiary-aged faults. We hypothesize that the Recent, active faults that produced the tufa through hotspring

    2004-07-27

    We were tasked with developing a coining technique that would evaluate the feasibility of using a pressing, or coining process to imprint a one-dimensional sinusoidal pattern onto a thin disk specimen. We performed finite element method simulations of the coining process, designed, built, and tested a coining apparatus and tested surrogate materials, and coined a sample of special nuclear material. The preliminary results were encouraging. The pressing of a 3-mm diameter by {approx}100 {micro}m thick disc to 500 pounds of pressure produced a flat part with a 1-{micro}m deep by 50-{micro}m period sine wave pattern covering all of the surface and thus demonstrated the method for replicating ultraprecision, mesoscale features onto a near-net-shape metallic blank. This coining technique is being developed to provide specialty processing for the manufacturing of difficult to machine, millimeter-size components made from materials that present hazardous conditions. The technology is versatile and can be used to imprint a wide range of features, or profiles into two opposing surfaces. The coining process requires a simple, conceivably hand held tool, which efficiently produces ultra-precision work pieces without the production of byproducts such as machining chips, or grinding swarf. It shows promise for use on ductile materials that cannot be precision machined with conventional single crystal diamond tooling. As a production process, it can be used to reduce manufacturing costs where large numbers of ultra-precision, repetitive designs are required.

  10. Solar cooking trends--A preliminary report

    SciTech Connect

    Blum, B.L.

    1992-12-31

    This report discusses early results of research on trends in solar cooking worldwide and the key factors in those trends. It is based on household interviews in Belize, Honduras and Nicaragua and mail surveys from scattered individuals and promotion projects worldwide. Household interviews from six more countries will be included in future reports. Early data indicate that where solar cooking has been introduced an immediate, rapid increase in awareness and interest in solar cooking is followed by slow, sustained growth in actual solar cooking two or three years later, after an incubation period. Access to information and affordable materials for the cookers are important. Individual users and promoters both identify similar key elements for effective promotion projects, but in current projects many are often missing. Even so, successes of these small-scale efforts verify the benefits and acceptability of solar cooking to families in many regions, and should encourage much broader promotion efforts. Future reports will explore various economic, technical, cultural and environmental factors in solar cooking use as guides for larger efforts.

    1996-08-01

    This report is a summary of environmental information gathered during a review of the documents pertaining to Project Rulison and interviews with personnel who worked on the project. Project Rulison was part of Operation Plowshare (a program designed to explore peaceful uses for nuclear devices). The project consisted of detonating a 43-kiloton nuclear device on September 10, 1969, in western Colorado to stimulate natural gas production. Following the detonation, a reentry well was drilled and several gas production tests were conducted. The reentry well was shut-in after the last gas production test and was held in standby condition until the general cleanup was undertaken in 1972. A final cleanup was conducted after the emplacement and testing wells were plugged in 1976. However, some surface radiologic contamination resulted from decontamination of the drilling equipment and fallout from the gas flaring during drilling operations. With the exception of the drilling effluent pond, all surface contamination at the Rulison Site was removed during the cleanup operations. All mudpits and other excavations were backfilled, and both upper and lower drilling pads were leveled and dressed. This report provides information regarding known or suspected areas of contamination, previous cleanup activities, analytical results, a review of the regulatory status, the site`s physical environment, and future recommendations for Project Ruhson. Based on this research, several potential areas of contamination have been identified. These include the drilling effluent pond and mudpits used during drilling operations. In addition, contamination could migrate in the gas horizon.

    An intercomparison and assessment of the tropical behaviour of coupled general circulation models (CGCMs) is being carried out, to identify common strengths and weaknesses and thus guide future CGCM development. The work is being carried out as part of the CLIVAR climate research programme, as a WG-SIP (Working Group on Seasonal to Interannual Prediction) project called STOIC (Study of Tropical Oceans In CGCMs), organised by Michael Davey. This project complements a companion sub-project called ENSIP (El Ni~ no Simulation Intercomparison Project) organised by Mojib Latif (Max- Planck-Institute for Meteorology) that focusses on equatorial Pacific CGCM behaviour (Latif et al. 1999). Previous coupled model assessments (Mechoso et al. 1995, Neelin et al. 1992, and ENSIP) have focussed on tropical Pacific behaviour. The aim of STOIC is to look at model performance in all tropical ocean regions. This status report contains a sample of the STOIC assessment work, highlighting mean and inter- annual equatorial sea surface temperatures and zonal windstresses. The intention is to submit STOIC and ENSIP papers in mid-1999 for publication together in a refereed journal.

    A registry has been established to document certain characteristics on a sizeable worldwide sample of individuals with savant syndrome, a rare but remarkable condition in which persons with developmental disabilities, brain injury, or brain disease have some spectacular "islands" of skill or ability that stand in jarring, marked contrast to overall handicap. Of the 319 savants included in the registry, 90% are congenital savants, while 10% are acquired savants. The registry includes individuals from 33 countries, with 70% from the United States or Canada. Sex distribution was 79% male vs. 21% female (4:1). This report summarizes the findings in the congenital savant syndrome category of the registry. Among the individuals with congenital savant syndrome, the most common underlying disability was Autistic Spectrum Disorder (75%); various other central nervous system (CNS) disorders were present in the other 25%. Fifty-five percent possessed a single special skill, while 45% had multiple skills. Music was the most frequent principal skill followed by art, memory, mathematics, calendar calculating, language, visual-spatial/mechanical, athletic, computer, extrasensory perception, and other skills.

    A master plan for the Yakima/Klickitat Production Project (YKPP) was developed by the Northwest Power Planning Council (Council) on October 15, 1987, as a reasonable basis upon which the Bonneville Power Administration (BPA) could proceed to fund predesign work on the project. The Council approved the predesign work on the condition that eight preliminary tasks were completed. These tasks are: Task 1. Agreement on a refined statement of project goals. Task 2. Completion of a technical analysis of water supplies. Task 3. Completion of an experimental design plan. Task 4. Development of a harvest management plan. Task 5. Assessment of potential genetic risks. Task 6. Project coordination with all other affected parties. Task 7. Submission of a preliminary design report to the Council. Task 8. Develop a project management structure. The preliminary design report summarizes the work completed on these tasks. It provides a description of the preliminary design, engineering, and construction phases of project development, and gives an estimate of project costs. Also included is a description of other studies that were conducted to support YKPP planning. The results of studies conducted during the last 30 months indicate that hatchery facilities can be built in the Yakima and Klickitat subbasins to provide harvest benefits and to supplement natural production. Planning for the Yakima subbasin is at a more advanced stage of development than for the Klickitat subbasin because of greater availability of basic resource information. The information needed to proceed with final design and construction for the Klickitat subbasin will be available by 1992, as ongoing predesign work continues. This schedule is consistent with the anticipated phased completion of the YKPP by 1997.

The Survey is being conducted by DOE's Office of Environment, Safety and Health. The SNLL Survey is a portion of the larger, comprehensive DOE Environmental Survey encompassing all major operating facilities of DOE. The DOE Environmental Survey is one of a series of initiatives announced on September 18, 1985, by Secretary of Energy, John S. Herrington, to strengthen the environmental, safety, and health programs and activities within DOE. The purpose of the Environmental Survey is to identify, via a no fault'' baseline Survey of all the Department's major operating facilities, environmental problems and areas of environmental risk. The identified problem areas will be prioritized on a Department-wide basis in order of importance in 1989. The findings in this report are subject to modification based on the results from the Sampling and Analysis Phase of the Survey. The findings are also subject to modification based on comments from the Albuquerque Operations Office concerning the technical accuracy of the findings. The modified preliminary findings and any other appropriate changes will be incorporated into an Interim Report. The Interim Report will serve as the site-specific source for environmental information generated by the Survey, and ultimately as the primary source of information for the DOE-wide prioritization of environmental problems in the Survey Summary Report. 43 refs., 21 figs., 24 tabs.

As a Preliminary Report, the contents are subject to revisions, which will be made in a forthcoming Interim Report, based on Albuquerque Operations Office review and comments on technical accuracy, the results of the sampling and analyses, and other information that may come to the Survey team's attention prior to issuance of the Interim Report. The Pinellas Plant is currently operated for DOE by the General Electric Company-Neutron Devices Department (GENDD). The Pinellas Survey is part of the larger DOE-wide Environmental Survey effort announced by Secretary John S. Herrington on September 18, 1985. The purpose of this effort is to identify, via no fault'' baseline Surveys, existing environmental problems are areas of environmental risk at DOE facilities and to rank them on a DOE-wide basis. This ranking will enable DOE to more effectively establish priorities for addressing environmental problems and allocate the resources necessary to correct these problems. Because the Survey is no fault'' and is not an audit,'' it is not designed to identify specific isolated incidents of noncompliance or to analyze environmental management practices. Such incidents and/or management practices will, however, be used in the Survey as a means of identifying existing and potential environmental problems. 55 refs., 37 figs., 37 tabs.

(1967, 1976), first in rocks collected from the hot and dry Negev desert and later in rocks in the frigid Ross Desert of Southern Victoria Land, Antarctica. The extremely inhospitable climatic conditions in both places has led to the suggestion that these organisms have very low rates of metabolism and may, in addition, be very old (FRIEDMANN 1982). Our preliminary measurements showed a 14C deficiency indicating a carbon age in the order of magnitude of 10(3) years.

    Th9 is a new T cell subset characterized by IL-9 production. It has been reported that serum IL-9 levels are related with symptom severity in patients with allergic rhinitis (AR). This study is aimed at investigating whether serum IL-9 may be modulated by sublingual immunotherapy (SLIT) in patients with persistent AR due to Parietaria allergy. Twenty-one AR patients (9 males, median age 41 years) successfully treated with SLIT and 52 AR patients (25 males, median age 34 years) treated only with drugs were evaluated during the pollen season. Serum IL-9 was dosed in all patients. SLIT-treated patients showed significantly lower serum IL-9 levels than untreated AR patients (p <0.0001). In conclusion, this preliminary study shows that a single pre-seasonal SLIT course might modulate serum IL-9.

    The scope of this preliminary report is to illustrate the performance characteristics of an electronically-controlled axis-traction handle. Preclinical testing was conducted with a prototype of the innovative device, using a childbirth simulator. The simulated forceps deliveries demonstrated that the innovative device allows the obstetrician to measure (unencumbered by dials, scales and cable connections) the traction applied, to be alerted when the preset 50 lbs (22.68 kg) safety limit is approached, and to generate a hard copy print-out of the traction data. The electronically-controlled axis-traction handle represents a major technologic advance, that could help improve the training and safe practice of forceps deliveries. © 2010 The Author.

    In this preliminary report the divergence times for the major primate groups are given, calculated from a study by comparative determinant analysis of 69 proteins (equaling 0.1% of the whole genetic information). With an origin of the primate order set at 80 million years before present, the ages of the last common ancestors (LCAs) of man and the major primate groups obtained this way are as follows: Pan troglodytes 5.2; Gorilla gorilla 7.4; Pongo pygmaeus 19.2; Hylobates lar 20.3; Old World monkeys 31.4; Lagothrix lagotricha 46.0; Cebus albifrons 59.5; three lemur species 67.0, and Galago crassicaudatus 73.3 million years. The LCA results and the approach are shortly discussed. A full account of this extended investigation including results on nonprimate mammals and on the determinant structures and the immunologically derived evolutionary rates of the proteins analyzed will be published elsewhere.

    As a preliminary comunication, the authors report a somatometric study carried out in 315 full term newborns from different socioeconomic situation; 152 were born at the Hospital General, S.S.A. and 163, in a private hospital where middle and high class families are attended. The information is grouped on whether measurements are related to physical growth, th state of nutrition or to physical development. Several conditions which necessarily must be taken as independent variables in a study of this sort, such as the age of the parents, but specially of the mother, the period of gestation and of course, the socioeconomic level, were analyzed. The finding of up to 17% of case with height under 47 cm. and/or weight under 2,500 g., outstands the necessity to study the homeorrhesis phenomenon as a very important detail in this type of material.

    2003-01-01

    Badlands National Park is host to perhaps the most scenic geology and landscape features in the Western Interior region of the United States. Ongoing erosion that forms the "badlands" exposes ancient sedimentary strata of Late Cretaceous through Oligocene age. Quaternary erosional and depositional processes are responsible for most of the modern landscape features in the park and surrounding region. This report provides a basic overview of the park geology The discussions presented within include both well-established concepts and theories and new, preliminary data and interpretations. Much emphasis is placed on presenting information about the oldest and least studied rocks in the park (particularly the Late Cretaceous and earliest Tertiary deposits that underlie the White River beds throughout the park region). Rock formations and selected fossils they contain are described. Faults, folds, unconformities, and other geologic structures in the North Unit of the park are illustrated, including features associated with the Sage Creek anticline and fault system.

  13. The extended Kasai portoenterostomy for biliary atresia: A preliminary report

    Aims: In 1955, Professor Morio Kasai first performed a hepatic portoenterostomy. Since then, the procedure has changed the lives of children with biliary atresia (BA). We report our initial experience in performing “extended” Kasai portoenterostomy (KPE), a modification of the original procedure. Materials and Methods: Since 2013, we have used the technique of “extended KPE” and prospectively recorded data on all children undergoing this operation. Data on demographics, clinical features, liver function tests, and perioperative cholangiogram findings were collected. Outcome of KPE was measured by Jaundice Disappearance Rate (JDR) and Native Liver Survival Rate (NLSR). We present our preliminary results from a 30-month period (February 2013 to May 2015). Results: Thirty-one children underwent KPE during this period (19 males) and only 1 child had biliary atresia splenic malformation (BASM). The mean age at KPE was 73 ± 24 days. Five (16.1%) children were more than 90 days old at the time of KPE. Fourteen children cleared jaundice (JDR 45.2%). Eleven (35.5%) children developed episodes of cholangitis, of whom 8 had early cholangitis (within 3 months of the operation). The proportion of children who survived with their own liver 6 months after KPE (NLSR) was 84.2%. Of those children older than 90 days, 2 cleared jaundice and have survived with their native livers for more than 16 months. Conclusion: In our preliminary report of 31 children, we conclude that the extended KPE leads to increased jaundice clearance and improved NLSR in children with BA. PMID:27046977

    Introduction The research was conducted among patients of the Department of Perinatology and Gynaecology of the Poznań University of Medical Sciences. Its aim was to investigate the influence of overweight and obesity on female sexuality during the perimenopausal period. Preliminary results of the research are presented in the thesis, which was as a matter of fact intended as a preliminary report. The examination of sexual functions of the patients was performed with the use of the Female Sexual Function Index (FSFI) form. Material and methods Sixty-one women during the perimenopausal period filled out the survey, with the average age of these women being 51 years. Forty-two of the examined women had an appropriate body mass index (BMI), i.e. between 18.5 and 25, while for 19 of the women, the BMI was above normal. For statistical analysis and in order to assess the differences between the two above-mentioned groups of patients, the nonparametric Mann-Whitney test was applied. A statistically significant value was assumed at p < 0.05. The results of the conducted research indicated no such difference between the women with differing BMI for the specific domains of the FSFI test. Results The results obtained show that research in the area needs to be continued. Conclusions All the hitherto existing scientific studies also seem to indicate that the influence of overweight and obesity on female sexuality during the perimenopause has not yet been unambiguously proven. Beyond any doubt, however, sexual disorders appear in women at this time of life and the factors which determine them can vary greatly. Given the character of the situation, women ought to be supported both by a team of specialists representing different branches of medicine as well as by their relatives. The whole situation also calls for more research of the important subject matter. PMID:26327896

    The May 12, 2008 Great Wenchuan Earthquake has resulted in more than 68,858 deaths and losses in the hundreds of billions RMB as of May 30, 2008, and these numbers will undoubtedly increase as more information becomes available on the extent of the event. Immediately after the earthquake, the China Earthquake Administration (CEA) responded quickly by sending teams of experts to the affected region, eventually including over 60 staff members from the Institute of Engineering Mechanics (IEM). This paper reports preliminary information that has been gathered in the first 18 days after the event, covering seismicity, search and rescue efforts, observed ground motions, and damage and loss estimates. The extensive field investigation has revealed a number of valuable findings that could be useful in improving research in earthquake engineering in the future. Once again, this earthquake has shown that the vertical component of ground motion is as significant as horizontal ground motions in the near-source area. Finally, note that as more information is gathered, the numbers reported in this paper will need to be adjusted accordingly.

    The NIST Center for Neutron Research (NCNR) is a reactor-laboratory complex providing the National Institute of Standards and Technology (NIST) and the nation with a world-class facility for the performance of neutron-based research. The heart of this facility is the NIST research reactor (aka NBSR); a heavy water moderated and cooled reactor operating at 20 MW. It is fueled with high-enriched uranium (HEU) fuel elements. A Global Threat Reduction Initiative (GTRI) program is underway to convert the reactor to low-enriched uranium (LEU) fuel. This program includes the qualification of the proposed fuel, uranium and molybdenum alloy foil clad in an aluminum alloy, and the development of the fabrication techniques. This report is a preliminary version of the Safety Analysis Report (SAR) that would be submitted to the U.S. Nuclear Regulatory Commission (NRC) for approval prior to conversion. The report follows the recommended format and content from the NRC codified in NUREG-1537, “Guidelines for Preparing and Reviewing Applications for the Licensing of Non-power Reactors,” Chapter 18, “Highly Enriched to Low-Enriched Uranium Conversions.” The emphasis in any conversion SAR is to explain the differences between the LEU and HEU cores and to show the acceptability of the new design; there is no need to repeat information regarding the current reactor that will not change upon conversion. Hence, as seen in the report, the bulk of the SAR is devoted to Chapter 4, Reactor Description, and Chapter 13, Safety Analysis.

    2009-01-12

    commercial readiness of an emissions control system that is specifically designed to meet the environmental compliance requirements of these smaller coal-fired EGUs. The multi-pollutant control system is being installed and tested on the AES Greenidge Unit 4 (Boiler 6) by a team including CONSOL Energy Inc. as prime contractor, AES Greenidge LLC as host site owner, and Babcock Power Environmental Inc. as engineering, procurement, and construction contractor. All funding for the project is being provided by the U.S. Department of Energy, through its National Energy Technology Laboratory, and by AES Greenidge. AES Greenidge Unit 4 is a 107 MW{sub e} (net), 1950s vintage, tangentially-fired, reheat unit that is representative of many of the 440 smaller coal-fired units identified above. Following design and construction, the multi-pollutant control system will be demonstrated over an approximately 20-month period while the unit fires 2-4% sulfur eastern U.S. bituminous coal and co-fires up to 10% biomass. This Preliminary Public Design Report is the first in a series of two reports describing the design of the multi-pollutant control facility that is being demonstrated at AES Greenidge. Its purpose is to consolidate for public use all available nonproprietary design information on the Greenidge Multi-Pollutant Control Project. As such, the report includes a discussion of the process concept, design objectives, design considerations, and uncertainties associated with the multi-pollutant control system and also summarizes the design of major process components and balance of plant considerations for the AES Greenidge Unit 4 installation. The Final Public Design Report, the second report in the series, will update this Preliminary Public Design Report to reflect the final, as-built design of the facility and to incorporate data on capital costs and projected operating costs.

    The purpose of this report is to present the preliminary findings made during the Environmental Survey, February 22--29, 1988, at the US Department of Energy (DOE) Lawrence Berkeley Laboratory (LBL) in Berkeley, California. The University of California operates the LBL facility for DOE. The LBL Survey is part of the larger DOE-wide Environmental Survey announced by Secretary John S. Herrington on September 18, 1985. The purpose of this effort is to identify, via no fault'' baseline Surveys, existing environmental problems and areas of environmental risk at DOE facilities, and to rank them on a DOE wide basis. This ranking will enable DOE to more effectively establish priorities for addressing environmental problems and allocate the resources necessary to correct them. Because the Survey is no fault'' and is not an audit,'' it is not designed to identify specific isolated incidents of noncompliance or to analyze environmental management practices. Such incidents and/or management practices will, however, be used in the Survey as a means of identifying existing and potential environmental problems. The LBL Survey was conducted by a multidisciplinary team of technical specialists headed and managed by a Team Leader and Assistant Team Leader from DOE's Office of Environmental Audit. A complete list of the LBL Survey participants and their affiliations is provided in Appendix A. 80 refs., 27 figs., 37 tabs.

    1984-01-01

    A 5-month partial study (February to July 1983) was completed in Suisun Bay, a shallow embayment of San Francisco Bay, Calif., to determine characteristic heavy metal concentrations present in sediments and organisms (Corbicula clams) prior to possible discharge of San Luis Drain irrigation tile return water. Preliminary results show sediments are typical of other San Francisco Bay study sites, ranging from coarse sands to fine silt-clays. The sediments are enriched in manganese and low in organic carbon; iron is moderately enriched, with acid-extractable iron concentrations of 162-3,521 micro-g/g. Sediment concentrations of silver, zinc, lead, and cadmium measured between April and July are reported. Previous area studies have shown increased concentrations during autumn and winter, a period not covered in the data set. Due to insufficient data, interpretations are incomplete. Clam-tissue burdens for silver and zinc are similar to those found in Corbicula from pristine areas. Lead concentrations are typically below the 2-micrograms/g detection level. Corbicula do show indications of more tissue enrichment for cadmium and copper at estuarine stations than at riverine stations. (USGS)

    The use of motion-sensing video game software has provided users with the ability to mimic movements in many sports such as baseball, tennis, and boxing. Epidemiology on injuries and overuse of motion-sensing video game systems is minimal because the systems have only been available for 2 years. This case series report presents preliminary data on injuries related to the game systems from the first full year of use. Methods included the use of secondary data from the National Electronic Injury Surveillance System for 2007. The query found 21 cases of injury related to the use of the "Wii" video game system (Nintendo of America Inc., Redmond, WA). Results indicated that females were more prone to injuries, and the mean age was 16 years. Most injuries were soft tissue in nature and located in the shoulders, hands and fingers, and the face and neck region. Our discussion includes prevention strategies for reducing injury risk when playing motion-sensing video games.

    The Savannah River National Laboratory is collaborating with Alfred University to evaluate the potential for additives in borosilicate glass to improve sulfur retention. This preliminary report provides further background on the incorporation of sulfur in glass and outlines the experiments that are being performed by the collaborators. A simulated waste glass composition has been selected for the experimental studies. The first phase of experimental work will evaluate the impacts of BaO, PbO, and V{sub 2}O{sub 5} at concentrations of 1.0, 2.0, and 5.0 wt % on sulfate retention in simulated high level waste borosilicate glass. The second phase of experimental work will evaluate the effects of time at the melt temperature on sulfur retention. The resulting samples will be characterized to determine the amount of sulfur remaining as well as to identify the formation of any crystalline phases. The results will be used to guide the future selection of frits and glass forming chemicals in vitrifying Department of Energy wastes containing high sulfur concentrations.

    This document, the Preliminary Design Report (PDR) for the Brookhaven Ultraviolet Free Electron Laser (UV FEL) facility, describes all the elements of a facility proposed to meet the needs of a research community which requires ultraviolet sources not currently available as laboratory based lasers. Further, for these experiments, the requisite properties are not extant in either the existing second or upcoming third generation synchrotron light sources. This document is the result of our effort at BNL to identify potential users, determine the requirements of their experiments, and to design a facility which can not only satisfy the existing need, but have adequate flexibility for possible future extensions as need dictates and as evolving technology allows. The PDR is comprised of three volumes. In this, the first volume, background for the development of the proposal is given, including descriptions of the UV FEL facility, and representative examples of the science it was designed to perform. Discussion of the limitations and potential directions for growth are also included. A detailed description of the facility design is then provided, which addresses the accelerator, optical, and experimental systems. Information regarding the conventional construction for the facility is contained in an addendum to volume one (IA).

    This report presents the preliminary findings from the first phase of the Environmental Survey of the United States Department of Energy (DOE) Mound Plant, conducted August 18 through 29, 1986. The objective of the Survey is to identify environmental problems and areas of environmental risk associated with the Mound Plant. The Survey covers all environmental media and all areas of environmental regulation. It is being performed in accordance with the DOE Environmental Survey Manual. The on-site phase of the Survey involves the review of existing site environmental data, observations of the operations carried on at the Mound Plant, and interviews with site personnel. The Survey found no environmental problems at the Mound Plant that represent an immediate threat to human life. The environmental problems identified at the Mound Plant by the Survey confirm that the site is confronted with a number of environmental problems which are by and large a legacy from past practices at a time when environmental problems were less well understood. Theses problems vary in terms of their magnitude and risk, as described in this report. Although the sampling and analysis performed by the Mound Plant Survey will assist in further identifying environmental problems at the site, a complete understanding of the significance of some of the environmental problems identified requires a level of study and characterization that is beyond the scope of the Survey. Actions currently under way or planned at the site, particularly the Phase II activities of the Comprehensive Environmental Analysis and Response Program (CEARP) as developed and implemented by the Albuquerque Operations Office, will contribute toward meeting this requirement. 85 refs., 24 figs., 20 tabs.

    Introduction Midline lumbar fusion (MIDLF) using cortical bone trajectory is an alternative method of transpedicular spinal fusion for degenerative disease. The new entry points’ location and screwdriving direction allow the approach-related morbidity to be reduced. Aim To present our preliminary experience with the MIDLF technique on the first 5 patients with lumbar degenerative disease and with follow-up of at least 6 months. Material and methods Retrospective analysis was performed on the first 5 patients with foraminal (4) or central (1) stenosis operated on between December 2014 and February 2015. Three patients were fused at L4–L5 and two at the L5–S1 level. Results No intra- or post-operative complications occurred with this approach. An improvement regarding the leading symptom in the early postoperative period (sciatica 4/4, claudication 1/1) was achieved in all patients. The mean improvements in the visual analogue scale for low back and leg pain were 2.2 and 4.8 respectively. The mean Oswestry Disability Index scores were 52% (range: 16–82%) before surgery and 33% (range: 12–56%) at 3-month follow-up (mean improvement 19%). At the most recent follow-up, 4 patients reported the maintenance of the satisfactory result. The early standing and follow-up X-rays showed satisfactory screw placement in all patients. Conclusions In our initial experience, the MIDLF technique seems to be an encouraging alternative to traditional transpedicular trajectory screws when short level lumbar fusion is needed. Nevertheless, longer observations on larger groups of patients are needed to reliably evaluate the safety of the method and the sustainability of the results. PMID:27829938

    The object of the Control Preliminary Definition Program was to define a preliminary control system concept as a part of the Energy Efficient Engine program. The program was limited to a conceptual definition of a full authority digital electronic control system. System requirements were determined and a control system was conceptually defined to these requirements. Areas requiring technological development were identified and a plan was established for implementing the identified technological features, including a control technology demonstration. A significant element of this program was a study of the potential benefits of closed-loop active clearance control, along with laboratory tests of candidate clearance sensor elements for a closed loop system.

    Prior studies show promising results of the gastric peroral endoscopic pyloromyotomy (G-POEM) procedure for treatment of refractory gastroparesis. One major technical challenge involved in this procedure is identifying the pyloric muscular ring (PMR). The aim of this study is to establish a reliable method for identification of the PMR during G-POEM. Fluoroscopy-guided G-POEM was performed by placing an endoclip at the 9 to 11'o clock position at the pylorus for identification of PMR. Conventional G-POEM was performed by observation of blue colored mucosa at the pylorus area as an indirect marker for PMR. The degree of the PMR identification was graded into well identified, identified, and not identified based on the appearance of the PMR. Procedure times were accurately documented. Gastroparesis cardinal symptoms index and gastric emptying scintigraphy were evaluated before and after the procedure. Fourteen patients were studied, seven underwent fluoroscopy-guided G-POEM, and seven patients underwent conventional G-POEM. All procedures achieved technical success and no adverse events occurred. In the seven patients who underwent fluoroscopy-guided G-POEM, the PMR was well identified in four patients and identified in three patients. In the seven patients who underwent conventional G-POEM, the PMR was identified in four patients and not identified in three patients. The average time to complete the fluoroscopy-guided G-POEM was significantly shorter than that of the conventional G-POEM. Fluoroscopy-guided G-POEM by placement of an endoclip at the pylorus was a reliable and safe method to direct the orientation of the submucosal tunnel, to facilitate the location of the PMR, and to shorten the procedure time.

    2016-06-01

    Regular comparison of preliminary to final reports is a critical part of radiology resident and fellow education as prior research has documented substantial preliminary to final discrepancies. Unfortunately, there are many barriers to this comparison: high study volume; overnight rotations without an attending; the ability to finalize reports remotely; the subtle nature of many changes; and lack of easy access to the preliminary report after finalization. We developed a system that automatically compiles and emails a weekly summary of report differences for all residents and fellows. Trainees can also create a custom report using a date range of their choice and can view this data on a resident dashboard. Differences between preliminary and final reports are clearly highlighted with links to the associated study in Picture Archiving and Communication Systems (PACS) for efficient review and learning. Reports with more changes, particularly changes made in the impression, are highlighted to focus attention on those exams with substantive edits. Our system provides an easy way for trainees to review changes to preliminary reports with immediate access to the associated images, thereby improving their educational experience. Departmental surveys showed that our report difference summary is easy to understand and improves the educational experience of our trainees. Additionally, interesting descriptive statistics help us understand how reports are changed by trainee level, by attending, and by exam type. Finally, this system can be easily ported to other departments who have access to their Health Level 7 (HL7) data.

    1980-01-01

    Preliminary results are described of a xenon-123 filled device to serve as a combination iodine-123 generator/iodination kit. Xenon-123 is produced in the Brookhaven Linac Isotope Producer (BLIP) by the reaction /sup 127/I(p, 5n)/sup 123/Xe. The device consists of a small glass ampoule containing an internal glass breakseal and a flanged neck on which is crimped a multi-injection type septum. The ampoule contains a hydrogen sulfide atmosphere to assure that the iodine generated from the decay of the xenon is in the form of iodide. Following an adequate period for xenon-123 to decay (this period can be used for shipment), a needle is forced through the septum breaking the seal and residual gases are pumped off. The iodine-123 in the form of iodide can then be rinsed from the ampoule with any desired solvent or reagent added directly to the device to carry out an iodination in an enclosed environment. Preliminary results of both iodine recovery and iodinations have been promising.

    On August 24, 1992, at 1:40 a.m. eastern daylight time (EDT), rain bands associated with Hurricane Andrew reached the eastern coast of Florida. At 4:45 a.m. EDT, Hurricane Andrew made landfall 35 miles southeast of Miami at Homestead, with sustained winds of 145 miles per hour (mph) and gusts of 164 mph. These winds extended 45 miles outward of the storm center. The storm moved across the state at 18 mph toward the Gulf of Mexico (Figure 1). The tidal surge on the eastern coast was estimated at 7-19 feet. During the storm, approximately 2.5 million Florida residents were left without electrical power, and approximately 56,000 family dwelling units were destroyed or severely damaged. This report presents preliminary data from Florida medical examiner (ME) offices about deaths attributed to Hurricane Andrew.

    SciTech Connect

    Mjolsness, E.; Reinitz, J.; Garrett, C.D.; Sharp, D.H.

    1993-07-29

    In this paper we outline a model which incorporates development processes into an evolutionary frame work. The model consists of three sectors describing development, genetics, and the selective environment. The formulation of models governing each sector uses dynamical grammars to describe processes in which state variables evolve in a quantitative fashion, and the number and type of participating biological entities can change. This program has previously been elaborated for development. Its extension to the other sectors of the model is discussed here and forms the basis for further approximations. A specific implementation of these ideas is described for an idealized model of the evolution of a multicellular organism. While this model doe not describe an actual biological system, it illustrates the interplay of development and evolution. Preliminary results of numerical simulations of this idealized model are presented.

    Preliminary results of a two-year burial experiment in granite are discussed. Three compositions of simulated alkali borosilicate waste glasses were placed in boreholes approximately 350 meters deep. The glass sample configurations include mini-cans (stainless steel rings into which glass has been cast) and pineapple slices (thin sections from cylindrical blocks). Assemblies of these glass samples were prepared by stacking them together with granite, compacted bentonite and metal rings to provide several types of interfaces that are expected to occur in the repository. The assemblies were maintained at either ambient mine temperature (8 to 10/sup 0/C) or 90/sup 0/C. The glasses were analyzed before burial and after one month storage at 90/sup 0/C. The most extensive surface degradation occurred on the glasses interfaced with bentonite. In general, very little attack was observed on glass surfaces in contact with the other materials. The limited field and laboratory data are compared.

  4. Preliminary report on antimicrobial activity of Helichrysum litoreum Guss.

    The authors present the preliminary results regarding the antibacterial action of extracts of Helichrysum litoreum Guss. The leaves and the young stems of this species, gathered on the slopes of Mt Vesuvius, in the Campania region, were ground and four extracts were made as follows: with dichloromethane, ethanol and water (70:30 v/v), water and methanol. The antibacterial activity of each of the samples was tested in order to determine which of the extracts was more antibacterial. The results of the test showed that the extract with the ethanol/water (70/30 v/v) was the most active one. This will allow us to advance in the research, purifying the extract and hopefully identifying the active principles.

    Determining what is the ideal acute management of type III lesions is controversial. The reconstruction of coracoclavicular ligaments is a fundamental part of the surgical management of these lesions. The records of patients with acute acromioclavicular dislocation treated with open reduction and fixation with highly resistant sutures were reviewed. The preliminary results were assessed at the 3-month follow-up. Twelve patients were included, all of them males; mean age was 28 years. Three were Rockwood grade III, one grade IV, and 8 grade V. The mean time elapsed between the injury and the surgery was 9 days. According to the Constant scale 11 patients had excellent results and one had good results. Only one patient developed a seroma. Radiographic reduction was maintained in all patients. The anatomical reconstruction of coracoclavicular ligaments reduces complications considerably, especially when such reconstruction is made using materials with a grip strength similar to the one offered by native ligaments.

    With the discovery of bona fide extraterrestrial materials in the Stardust Interstellar Dust Collector, NASA now has a fundamentally new returned sample collection, after the Apollo, Antarctic meteorite, Cosmic Dust, Genesis, Stardust Cometary, Hayabusa, and Exposed Space Hardware samples. Here, and in companion papers in this volume, we present the results from the Preliminary Examination of this collection, the Stardust Interstellar Preliminary Examination (ISPE). We found extraterrestrial materials in two tracks in aerogel whose trajectories and morphology are consistent with an origin in the interstellar dust stream, and in residues in four impacts in the aluminum foil collectors. While the preponderance of evidence, described in detail in companion papers in this volume, points toward an interstellar origin for some of these particles, alternative origins have not yet been eliminated, and definitive tests through isotopic analyses were not allowed under the terms of the ISPE. In this summary, we answer the central questions of the ISPE: How many tracks in the collector are consistent in their morphology and trajectory with interstellar particles? How many of these potential tracks are consistent with real interstellar particles, based on chemical analysis? Conversely, what fraction of candidates are consistent with either a secondary or interplanetary origin? What is the mass distribution of these particles, and what is their state? Are they particulate or diffuse? Is there any crystalline material? How many detectable impact craters (>100 nm) are there in the foils, and what is their size distribution? How many of these craters have analyzable residue that is consistent with extraterrestrial material? And finally, can craters from secondaries be recognized through crater morphology (e.g., ellipticity)?

    PubMed

    Alexander, K A; Smith, J S; Macharia, M J; King, A A

    1993-12-01

    A serosurvey of rabies antibodies among domestic dogs (Canis familiaris, n = 178), spotted hyaenas (Crocuta crocuta, n = 72) and African wild dogs (Lycaon pictus, n = 18) of the Masai Mara, Kenya, was carried out. Rabies antibodies were found in 9.6% of the domestic dog sera, but all wild dog and hyaena sera were negative. Rabies has been confirmed in this region among the above species as well as in a domestic cat (Felis catus) and a cow (Bos indicus) by fluorescent antibody tests (FAT) and/or histopathology. The disease was confirmed in three wild dogs in 1989 and in a fourth dog in early 1991. In 1992, a spotted hyaena attacked six people, one of whom died; the hyaena brain was positive for rabies. To date, rabies has been confirmed in one domestic cow (n = 22; 4.5%), one domestic cat (n = 9; 11.1%) and five domestic dogs (n = 32; 15.6%). The wild dog cases exhibited paralytic rabies whereas in the hyaena, domestic cat and domestic dogs furious rabies was observed. The dynamics of rabies in this ecosystem is not yet fully understood, but based on these preliminary data it is suspected that domestic dogs play a primary role in its maintenance.

    2004-12-01

    Ozone therapy is currently being used in the treatment of ischemic disorders, but the underlying mechanisms that result in successful treatment are not well known. This study assesses the effect of ozone therapy on the blood flow in the middle cerebral and common carotid arteries. Seven subjects were recruited for the therapy that was performed by transfusing ozone-enriched autologous blood on 3 alternate days over 1 week. Blood flow quantification in the common carotid artery (n = 14) was performed using color Doppler. Systolic and diastolic velocities in the middle cerebral artery (n = 14) were estimated using transcranial Doppler. Ultrasound assessments were conducted at the following three time points: 1) basal (before ozone therapy), 2) after session #3 and 3) 1 week after session #3. The common carotid blood flow had increased by 75% in relation to the baseline after session #3 (P < 0.001) and by 29% 1 week later (P = 0.039). In the middle cerebral artery, the systolic velocity had increased by 22% after session #3 (P = 0.001) and by 15% 1 week later (P = 0.035), whereas the diastolic velocity had increased by 33% after session #3 (P < 0.001) and by 18% 1 week later (P = 0.023). This preliminary Doppler study supports the clinical experience of achieving improvement by using ozone therapy in peripheral ischemic syndromes. Its potential use as a complementary treatment in cerebral low perfusion syndromes merits further clinical evaluation.

    2002-01-01

    Recently acquired geophysical data provide information on the geologic framework and its effect of groundwater flow and on stream/aquifer interaction in Yavapai County, Arizona. High-resolution aeromagnetic data reflect diverse rock types at and below the topographic surface and have permitted a preliminary interpretation of faults and underlying rock types (in particular, volcanic) that will provide new insights on the geologic framework, critical input to future hydrologic investigations. Aeromagnetic data map the western end of the Bear Wallow Canyon fault into the sedimentary fill of Verde Valley. Regional gravity data indicate potentially significant accumulations of low-density basin fill in Big Chino, Verde, and Williamson Valleys. Electrical and seismic data were also collected and help evaluate the approximate depth and extent of recent alluvium overlying Tertiary and Paleozoic sediments. These data will be used to ascertain the potential contribution of shallow ground-water subflow that cannot be measured by gages or flow meters and whether stream flow in losing reaches is moving as subflow or is being lost to the subsurface. The geophysical data will help produce a more robust groundwater flow model of the region.

    2002-03-01

    The objective of this prospective study was to evaluate preliminary results of an endoscopic-assisted surgical technique for patients suffering from chronic Achilles tendinopathies. Case series. Endoscopic operations were performed on 7 consecutive patients involved in recreational sports suffering from chronic Achilles tendon (AT) lesions in whom conservative treatment had failed. Diagnoses included 2 patients with pure peritendinitis, 4 with peritendinitis and degenerative tendinosis, and 1 with a chronic partial tear. Patients were preoperatively and postoperatively evaluated at a mean follow-up period of 16 months (range, 6 to 27 months) with a 0-100 points rating system. All patients were studied preoperatively with magnetic resonance imaging (MRI) and 6 were re-evaluated with the same procedure after surgery. All surgical interventions were performed on an ambulatory basis and 5 under local anesthesia. The surgical endoscopic technique consisted of peritenon release and debridement in cases with pure peritendinitis. In addition, 2 longitudinal tenotomies were performed in cases with degenerative tendinosis or partial tears. According to the scoring system used, all 7 patients had improved final outcome after surgery from a mean of 39 points preoperatively to 88 points postoperatively. The patient with an AT partial tear achieved the lowest score. The only complications were a minor hematoma and edema that resolved spontaneously. Postoperative MRI in patients with tendinosis failed to show evidence of degenerative areas. Endoscopic surgery may be a valid alternative to treat Achilles tendinopathies unresponsive to conservative treatment because of potential lower morbidity.

    The spinal injuries in workers have become a large scale health problem. The purpose of this study is to review the differences in the spine pathologies from incapacity to work, as well as factors that could alter the recovery time and the possibility of returning the patient to work. Statistical preliminary review study in 37 patients enrolled in the Instituto Mexicano del Seguro Social, workers, undertaken to spinal pathology surgery, comparing days of incapacity with proposed internationally, as well as his return to work. The results show that 37% of the patients studied are still active in the social security, 2 years after surgery. The days of disability generated by the pathology in this study group (212.3 days) are significantly higher than what is set on the Medical Disability Advisor (56 days, almost 4 times more). The study shows the need to develop the same analysis in other hospitals, comparing the proportion of cases that return to the work and total disability times for diagnostics.

  1. Preliminary design of atlas pulsed power machine. Final report

    Gribble, R.F.

    1996-04-03

    During the contract period from March 95 to March 96 I participated in the preliminary design of the Atlas pulsed power machine. As part of this task I performed of the order of 1000 circuit simulations for many different bank configurations, opening switches, and loads, and about 100 electrostatic field calculations. Results of the calculations were provided at regular Atlas design meetings or in the form of memorandums. I have almost completed the development of a 2D disk transmission line code to more accurately calculate asymmetric transient current and voltage caused by azimuthal variations, including switch timing jitter and local arc faults. This code is attached as a subroutine to the circuit simulation program. The purpose for most of the simulations was to provide information on bank damping requirements and load energy ranges for the different circuit configurations. A minimum transmission line insulation depth was determined from calculating the maximum expected dynamic load back voltage (I{times}{sup dL}/{sub dt}). Other simulations included fault effects, transmission line heating effects (including diffusion, melting, vaporization, ionization), and transmission line transients under various conditions. The line fault simulations using a lumped constant approximation to the 2D disk line provided useful information but even with about 600 elements, it has an upper limit on mode frequencies and tends to exaggerate some modes. Electrostatic (2D) field calculations were used to estimate fields of the transmission lines, insulators, and rail gap switches. Design of conductor surface contours to minimize the field near an insulator stack was one result of these calculations. Effects of biasing and insulator modifications of the rail gap switch was determined.

  14. Geoscience for Alaska's D-1 Lands: A preliminary report

    USGS Publications Warehouse

    Schmidt, Jeanine M.; Gamble, B.M.; Labay, K.A.

    2007-01-01

    Purpose of This Report This interim report follows from the June 2006 recommendations to Congress by the BLM concerning disposition of the d-1 lands. That report recommended lifting of a significant number of d-1 PLOs, through the ongoing land management process within the BLM (e.g. resource management planning areas), or through Congressional action. The strategic actions outlined in this document refer only to Federal lands under US Bureau of Land Management (BLM) jurisdiction that 1) are affected by temporary withdrawals from mineral entry and mineral leasing by PLOs made pursuant to the Section 17(d)(1) of the ANCSA; 2) have been identified by the BLM as candidates for possible lifting of these PLOs and restrictions (U.S. Bureau of Land Management, 2006); and 3) lie outside of current Federal parks, preserves, monuments, refuges, reserves, wilderness areas and military installations that are closed to mineral entry, because within those areas the potential lifting of the d-1 restrictions has no practical effect. The resulting lands discussed here comprise approximately 121,000 km2 (29.9 million acres) of Alaska (Table 1) that, pending final resolution of Native and State land claims, will or may remain under Federal (BLM) control, and could be opened to mineral entry. For the purposes of this report, only these 29.9 million acres will hereafter be referred to as 'd-1' lands. This report gives a brief overview of the spatial distribution and physiographic setting, mineral occurrences, and mineral resource potential of the d-1lands. It outlines further geoscience information which could be compiled, collected, and evaluated in order to make a more accurate and comprehensive examination of the potential for undiscovered, locatable mineral resources on these Federal lands. This information is intended to provide guidance to USGS program managers and Federal land managers on matters of future exploration, access needs, and consequences of land status changes.

    2005-01-01

    Mission-critical events are defined in the Jet Propulsion Laboratory s Flight Project Practices as those sequences of events which must succeed in order to attain mission goals. These are dependent on the particular operational concept and design reference mission, and are especially important when committing to irreversible events. Critical events include main engine cutoff (MECO) after launch; engine cutoff or parachute deployment on entry, descent, and landing (EDL); orbital insertion; separation of payload from vehicle or separation of booster segments; maintenance of pointing accuracy for power and communication; and deployment of solar arrays and communication antennas. The purpose of this paper is to report on the current practices in handling mission-critical events in design and operations at major NASA spaceflight centers. The scope of this report includes NASA Johnson Space Center (JSC), NASA Goddard Space Flight Center (GSFC), and NASA Jet Propulsion Laboratory (JPL), with staff at each center consulted on their current practices, processes, and procedures.

    Agent orange, a defoliant used in Vietnam, was a mixture of 2,4-DD and 2,4,5-TS. During manufacture 2,4,5-T was contaminated with TCDD, a compound with marked toxicity in some species of experimental animals. In 1979, the US Congress responded to concerns of Vietnam veterans by passing Public Law 96-151 mandating epidemiologic studies of the possible health effects on Vietnam veterans of exposure to herbicides and their associated dioxin contaminants. In 1983, CDC developed a protocol for a historical cohort study of US Army veterans who had served in heavily sprayed areas of Vietnam. A report on that study is presented.

    The behavioral, psychological, and sociological aspects of space travel, particularly with emphasis on longer duration missions, are discussed along with the biomedical aspects of space flight. These factors may strongly interact with the various psycho-social factors and as such they stand as an immensely important area of concern in and of themselves. A foundation for understanding weightlessness related medical problems through a discussion of the history of symptoms reported specific details on the major areas of concern and approaches to their investigation are presented. Also, discussion is given to the possibility of various countermeasures. Some indication of the effects of various biomedical changes in performance are also covered.

    Andrews, Larry A.; Williams, Randy J.

    1998-09-01

    Several types of commercial fiber optic connectors were characterized for potential use in a Sandia designed Laser Diode Ignition (LDI) system. The characterization included optical performance while the connectors were subjected to the more dynamic environmental conditions experienced in weapons applications. The environmental testing included temperature cycling, random vibration, and mechanical shock. This report presents a performance assessment of the fiber optic connectors and fiber included in the characterization. The desirable design features are described for a fiber optic connector that must survive the dynamic environment of weapon systems. The more detailed performance of each connector type will be included as resources permit.

  14. Lymphoma and other lymphoid lesions of the orbit. Preliminary report.

    Kleener, J

    1975-03-01

    The orbit differs from the rest of the organism, excluding the central nervous system, as concerns lymph drainage. This may possible explain some of the peculiar features in lymphoid orbital lesions. The lymphoid tumours of the orbit are discussed on the basis of the classification most widely applied. An illustrative case is reported and it is concluded that even if local therapy may prove successful, patients in whom orbital lymphoid tumours have been diagnosed should be kept under constant observation with a view to prompt institution of treatment upon evidence of generalized disease.

    A review of the literature and an extensive Medline search revealed that this is the first case report of the use of guaifenesin to increase sperm motility. A 32-year-old male presented for an infertility evaluation. He reported an inability to conceive with his wife after 18 months of unprotected intercourse. A semen analysis was performed that included spermatozoa count, liquefaction, morphology, motility, viscosity and volume. Initial results of the semen analysis demonstrated low sperm count and motility. The provider offered treatment with guaifenesin 600 mg extended release tablets twice daily. Two months after guaifenesin therapy the semen analysis was repeated that demonstrated marked improvement in both total sperm count and motility. Evidence for the effectiveness of guaifenesin is almost entirely anecdotal. Given the mechanism of action of guaifenesin, it is not clear from this case why the patient demonstrated such a large improvement in both sperm count and motility. Additional studies of the effects of guaifenesin on male fertility could yield information of the medication's effect on men with normal or decreased total sperm counts.

    The System Design Study (SDS), part of the Waste Technology Development Department at the Idaho National Engineering Laboratory (INEL), examined techniques available for the remediation of hazardous and transuranic waste stored at the Radioactive Waste Management Complex`s Subsurface Disposal Area at the INEL. Using specific technologies, system concepts for treating the buried waste and the surrounding contaminated soil were evaluated. Evaluation included implementability, effectiveness, and cost. The SDS resulted in the development of technology requirements including demonstration, testing, and evaluation activities needed for implementing each concept. This volume of the Systems Design Study contain four Appendixes that were part of the study. Appendix A is an EG&G Idaho, Inc., report that represents a review and compilation of previous reports describing the wastes and quantities disposed in the Subsurface Disposal Area of the Idaho National Engineering Laboratory. Appendix B contains the process flowsheets considered in this study, but not selected for detailed analysis. Appendix C is a historical tabulation of radioactive waste incinerators. Appendix D lists Department of Energy facilities where cementation stabilization systems have been used.

    In this study, 32 cases of cancer of the genito-urinary tract are discussed from the viewpoint of immunology. In eight cases treated surgically, there has been no evidence of recurrence over a period of 1-4 years. Those with a good immunological response have a satisfactory course. Patients with a good response have been treated by radical surgery depending on the stage of the tumour, whilst those with a poor response have been treated less radically by reduction of the tumour mass in the hope that a better response may develop. The authors of this report feel that the 'inhibition of the lymphocyte migration test' is a very important factor to evaluate in the study and immunological evolution of the patient. Also, and concerning cases with good immunological response, the poor results after surgery makes us consider the importance and value of blocking factors of the serum closely related to the B type lymphocytes.

  19. Shelf mounted ocean thermal energy conversion platform, revised preliminary report

    NASA Astrophysics Data System (ADS)

    1984-03-01

    This report relates model tests of a generic Ocean Thermal Energy Conversion (OTEC) platform. The objective of these tests is to aid in the evaluation of new OTEC designs and to present a data base for design purposes. The test plant has been designed to provide a data base for comparison with current and projected analytical tools as well as comparisons of results from one model configuration to another. The new conceptual OTEC designs are different from the typical offshore (jacket type) structure which is quite transparent to waves. The major difference is the addition of large submerged power production modules to the frame. These proposed modules offer a large surface area to obstruct the flow and thereby increase the global wave forces acting on the structure.

    A collection of high-precision tiltmeters is being operated at Pinon Flat Observatory, southern California, both to compare instruments and to measure tectonic deformation. We report on 1.2 years of data from four of these: two Michelson-Gale long fluid tiltmeters, one long center-pressure tiltmeter, and a shallow borehole tiltmeter. The three long-base instruments are all located on the same baseline, with a precise leveling line running between their end-monuments. At nontidal frequencies, only the two Michelson-Gale instruments show some coherence (gamma 2 = .3 for periods of 2 to 4 days), while the center-pressure instrument is correlated with air temperature at periods from a few days to a few weeks. The most stable tilt record shows a secular rate of 0.28 mu rad/a, which may be real. Over much longer times, leveling to specially stabilized bench-marks should confirm this. Comparing instruments has identified more and less successful measurement techniques; it appears that low-noise data will most probably be produced only by relatively complex and expensive instruments, though even for these, the operating costs over any reasonable lifetime will exceed the capital cost. Even the best existing sensors must be improved to measure continuous tectonic motions.

    Background: Over the past three decades, laparoscopic surgery has become a well-established alternative to open surgery in the management of ureteropelvic junction (UPJ) obstruction. Currently, several efforts are being made, aimed at further reducing the morbidity associated with conventional laparoscopy. We report our experience with modified umbilical port laparoscopic pyeloplasty in children. Materials and Methods: Children presenting with hydronephrosis secondary to UPJ obstruction formed the study group. A 5 mm endoscopic port was placed on the inferior umbilical crease. The two 3 mm instruments were introduced through puncture sites created a few mm superior and lateral to the endoscopic port, under vision. Total operating time, the time taken for insertion of double pigtail catheter, time taken for pyeloplasty anastomosis and complications were noted. Results: During the study period, 16 children underwent modified umbilical only access laparoscopic pyeloplasty. The total operating time and the time for insertion of double pigtail catheter were significantly more in our earlier half of cases. Conclusions: Modified umbilical port laparoscopic pyeloplasty reduces the morbidity associated with conventional multiport laparoscopy without the need of expensive multichannel cannulas, curved laparoscopic instruments and longer laparoscopic endoscopes. Though crossing instruments are a factor which prolongs the duration of surgery, it does not hinder complex suturing needed during pyeloplasty. PMID:27251522

    To describe the initial steps in the development and validation of a new self-reported instrument designed to assess daily rhythms of mood symptoms, namely, the Mood Rhythm Instrument. A multidisciplinary group of experts took part in systematic meetings to plan the construction of the instrument. Clarity of items, their relevance to evaluation of mood states, and the consistency of findings in relation to the available evidence on the biological basis of mood disorders were investigated. The internal consistency of the questionnaire was evaluated through Cronbach's alpha. All of the items proposed in a first version were well rated in terms of clarity. The items more frequently rated as "rhythmic" were related to the somatic symptoms of mood. Their peaks in 24 hours were more frequent in the morning. The items associated with affective symptoms of mood were rated as less rhythmic, and their peak in 24 hours occurred more frequently in the afternoon and evening. Males and females behaved more similarly with respect to somatic than behavioral-affective items. The second version of the Mood Rhythm Instrument had a Cronbach's alpha of 0.73. The proposed Mood Rhythm Instrument may be able to detect individual rhythms of cognitive and behavioral measures associated with mood states. Validation in larger samples and against objective measures of rhythms, such as actigraphy, is warranted.

    During the one-year period from March 2002 to March 2003 there were 89 firearm fatalities investigated by the Legal Medicine Organization of Iran in Tehran. We determined the characteristics of these 89 firearm deaths which comprised 0.83% of all postmortem examinations. Of these, 60.7% were homicides, 30.3% suicides, 4.5% accidental, and 4.5% unclassifiable. Most victims were young male. Military rifles were responsible for almost all suicides, whereas in homicide handguns were the preferred weapons. The most common site of entrance wounds in suicides were the under the chin (37%) and chest (25.9%). In homicide group, 42.6% of entrance wounds were located in the head. The suicidal gunshots were fired from contact/near contact range in 84.6% while this was the case in only two cases of the homicides. All but one of the suicides were committed at the garrisons or police stations. The unique pattern of suicide that was found in this series was not similar to that reported in earlier studies. We believe our pattern of firearm fatalities must be in great part due to the Iran's strict gun control regulations and cultural background.

    The Kemper County IGCC Project is an advanced coal technology project that is being developed by Mississippi Power Company (MPC). The project is a lignite-fueled 2-on-1 Integrated Gasification Combined-Cycle (IGCC) facility incorporating the air-blown Transport Integrated Gasification (TRIG™) technology jointly developed by Southern Company; Kellogg, Brown, and Root (KBR); and the United States Department of Energy (DOE) at the Power Systems Development Facility (PSDF) in Wilsonville, Alabama. The estimated nameplate capacity of the plant will be 830 MW with a peak net output capability of 582 MW. As a result of advanced emissions control equipment, the facility will produce marketable byproducts of ammonia, sulfuric acid, and carbon dioxide. 65 percent of the carbon dioxide (CO{sub 2}) will be captured and used for enhanced oil recovery (EOR), making the Kemper County facility’s carbon emissions comparable to those of a natural-gas-fired combined cycle power plant. The commercial operation date (COD) of the Kemper County IGCC plant will be May 2014. This report describes the basic design and function of the plant as determined at the end of the Front End Engineering Design (FEED) phase of the project.

    We have updated the list of the lizard species present in Qatar and produced the first distribution maps based on two field surveys in 2012 and 2013. We used the QND95/Qatar National Grid with a grid of 10 × 10 km squares for mapping. Our results show the occurrence of 21 lizard species in Qatar, from the 15 species indicated in the last biodiversity report conducted in 2004. The most abundant family found in Qatar is Gekkonidae with nine species (Bunopus tuberculatus, Cyrtopodion scabrum, Hemidactylus robustus, H. flaviviridis, H. persicus, Stenodactylus arabicus, S. slevini, S. doriae, Pseudoceramodactylus khobarensis), followed by Lacertidae with four species (Acanthodactylus schmidti, A. opheodurus, Mesalina brevirostris, M. adramitana), Agamidae with three species (Trapelus flavimaculatus, Uromastyx aegyptia, Phrynocephalus arabicus), Scincidae with two species (Scincus mitranus, Trachylepis septemtaeniata), and Varanidae (Varanus griseus), Sphaerodactylidae (Pristurus rupestris) and Trogonophiidae (Diplometopon zarudnyi) with one species each. The species richness fluctuated largely across Qatar between one and eleven species per grid square. We believe that the lizard fauna records in Qatar are still incomplete and that additional studies are required. However, our study here fills a gap concerning lizard biodiversity knowledge in the Gulf Region.

    Background To estimate the frequency and duration of detectable Zika virus (ZIKV) RNA in human body fluids, we prospectively assessed a cohort of newly infected participants in Puerto Rico. Methods We evaluated samples obtained from 150 participants (including 55 men) in whom ZIKV RNA was detected on reverse-transcriptase-polymerase-chain-reaction (RT-PCR) assay in urine or blood in an enhanced arboviral clinical surveillance site. We collected serum, urine, saliva, semen, and vaginal secretions weekly for the first month and then at 2, 4, and 6 months. All specimens were tested by means of RT-PCR, and serum was tested with the use of anti-ZIKV IgM enzyme-linked immunosorbent assay. Among the participants with ZIKV RNA in any specimen at week 4, biweekly collection continued until all specimens tested negative. We used parametric Weibull regression models to estimate the time until the loss of ZIKV RNA detection in each body fluid and reported the findings in medians and 95th percentiles. Results The medians and 95th percentiles for the time until the loss of ZIKV RNA detection were 14 days (95% confidence interval [CI], 11 to 17) and 54 days (95% CI, 43 to 64), respectively, in serum; 8 days (95% CI, 6 to 10) and 39 days (95% CI, 31 to 47) in urine; and 34 days (95% CI, 28 to 41) and 81 days (95% CI, 64 to 98) in semen. Few participants had detectable ZIKV RNA in saliva or vaginal secretions. Conclusions The prolonged time until ZIKV RNA clearance in serum in this study may have implications for the diagnosis and prevention of ZIKV infection. Current sexual-prevention guidelines recommend that men use condoms or abstain from sex for 6 months after ZIKV exposure; in 95% of the men in this study, ZIKV RNA was cleared from semen after about 3 months.

    The outcome of thulium laser urethrotomy for patients with urethral stricture had not been reported. The purpose of this study was to evaluate outcome of endourethrotomy with the thulium laser as a minimally invasive treatment for urethral stricture. Twenty-one consecutive patients with urethral stricture were evaluated by retrograde uroflowmetry, International Prostate Symptom Score (IPSS), and quality of life preoperatively at a single academic center. All patients were treated with thulium laser urethrotomy. All patients were followed up for 12-24 months postoperatively by uroflowmetry and by retrograde with voiding cystourethrogram every 3 months. And all patients were followed up by mailed questionnaire, including IPSS and quality of life. Retrograde endoscopic thulium laser urethrotomy was performed in all 21 patients. Most patients (N = 16; 76.2%) did not need any reintervention. Five patients developed recurrent strictures, of them two patients were treated by another laser urethrotomy, one patient was treated by open urethroplasty with buccal mucosa and the other two patients' reintervention were treated by urethral dilation. No intraoperative complications were encountered, although in 9.5% (N = 2) of patients, a urinary tract infection was diagnosed postoperatively. No gross hematuria occurred. Including two patients treated with repeat laser urethrotomy, 17(81.0%) showed good flow of urine (Q(ave)>16.0 ml/second) and adequate caliber urethra in retrograde urethrogram (RGU) 12 months after operation. Three (14.3%) patients showed narrow stream of urine (Q(ave)<8.0 ml/second) and urethral dilation was done every month or 2 months. There was one patient whose Q(ave) was between 8.0 and 16.0 ml/second. And this patient was treated by neither urethral dilation nor another laser urethrotomy. The thulium laser urethrotomy was a safe and effective minimally invasive therapeutic modality for urethral stricture. 2010 Wiley-Liss, Inc.

    1945-01-01

    At the request if the Liberian Government made through the Department of State of the United States Government, a party of geologists of the Geological Survey, United States Department of the Interior, was sent to Liberia to examine certain mineral deposits. The party, consisting of Walter H. Newhouse, Thomas P. Thayer, and Arthur P. Butler, Jr., left Washington, D.C., about December 1, 1943, and arrived in Monrovia, Liberia, December 12, 1943. They left Roberts Field, Liberia, May 5, 1944, and returned to Washington May 16, 1944. The geologists left Monrovia for field work in the interior on January 9, the delay of several weeks being due to difficulties in obtaining porters. Mr. Arthur Sherman, Mining Engineer for the Liberian Government, who accompanied the party into the interior, capably participated in the examination of the iron deposits and otherwise rendered invaluable assistance sue to his extensive knowledge of the native tribes and trails. President Tubman requested that the part first examined the iron deposits at Bomi Hills. At the close of the work there he requested that iron deposits in the Kpandemai Mountains be investigated. The party therefore left Bomi Hills on March 25 and arrived at Jordense Camp in the Kpandemai Mountain region on April 6. Four days were spent at this place examining the iron mineralization in the vicinity of Castle Rock, Sugar Loaf, and Mt. Wutivi of Kpandemai Mountains. On April 11 Kpandemai village reached. One day was spent on a long transverse into the Kpandemai Mountains to investigate the iron mineralization. The party left Kpandemai Village April 15 and arrived at Monrovia April 27. The iron mineralization in the portions of the Kpandemai Mountains investigated by the party is believed to be too low in grade and too small in amount to be of any present commercial interest and will not be considered further in this report.

    Since there have been side effects reported with the administration of corticosteroids epidurally, their application has been limited. Because some nonsteroidal antiinflammatory drugs have central and spinal antinociceptive actions, we have compared the effects of indomethacin (INM) given by the epidural route to methylprednisolone (MTP). This was a prospective, comparative study in an ambulatory pain care center. Two hundred six patients with recurrent low back pain (Visual Analog Scale >7) and radiculopathy after they had had 2 or more lumbar laminectomies with the diagnosis of "postlaminectomy syndrome" were randomly assigned to 1 of 3 groups. Group I (64 patients) was given 2 epidural injections of lyophilized INM 1 mg. Group II (60 patients) received 2 injections of 2 mg of INM at the same intervals. Group III (82 patients) was treated by 2 epidural injections of MTP 80 mg. In every case, the medication was diluted in 3 mL of 0.5% bupivacaine. Reductions of pain were assessed by changes in the Visual Analog Scale; physical activities, attitude, and medication intake were graded by the Pain Progress Score recorded before each treatment and 2 wk after the last. After each injection, all patients had pain relief to Visual Analog Scale <3. Increased analgesia (P < 0.05) was noted when a double dose of INM was used (Group II) or when 80 mg of MTP was given. The total average scores of the Pain Progress Score showed significant differences at the second injection in Groups II and III only. Physical activity, emotional attitudes, and medication intake were also improved but the changes were not statistically significant. In conclusion, in this group of patients, INM produced adequate analgesia in Groups I and II, with evidence suggesting that 2 mg of INM may produce a similar degree of pain relief as 80 mg of MTP after the second injection. Other nonsteroidal antiinflammatory drugs may be explored in the future for the same purpose.

    OBJECTIVES—A series of three recurrent central neurocytomas treated by gamma knife radiosurgery (GKRS), which were initially totally resected, are described. Up to now, no reports exist on this treatment modality for this rare tumour entity.
METHODS—Three male patients, aged between 20 and 25 years, presented with large intraventricular tumours. Total tumour removal was achieved by a single surgical procedure (one patient) or two operations (two patients). Neuropathological investigation showed a central neurocytoma, immunohistochemically all three tumours expressed a neuronal antigenetic profile typical for neurocytomas, and the MIB-1 proliferation index ranged from 2.4% to 8.7%. Each patient experienced a tumour recurrence after 5 to 6 years. The recurrence was multifocal in two and a singular tumour mass in one patient. Gamma knife radiosurgery was performed. The tumours were enclosed within the 30% to 60% isodoseline, and delivered a tumour marginal dose of 9.6 to 16 Gy. During the follow up period, the patients were tested clinically and the volume of the tumours was measured on MRI.
RESULTS—Within follow up periods of 1 to 5 years, control MRI showed a significant decrease of the tumour mass in all cases. None of the patients developed new neurological symptoms after GKRS. Two patients returned to work in their previous employment, whereas one patient remained permanently disabled due to a pre-existing visual impairment and abducens palsy.
CONCLUSION—GKRS proved to be a useful tool in the treatment of recurrent central neurocytomas. Tumour control and even tumour shrinkage can be achieved with a single procedure and a low risk of morbidity.

    The impaired decision-making with high risk-aversive behavior and elevated impulsivity are reported as a trait feature in anxiety disorders including panic disorder (PD). It is hypothesised that PD patients exhibit difficulties in executive functions which can influence patients behavioural strategies e.g. problem solving, decision making, planning, impulse control. The aim of this study was to asses decision making process, risk-taking and impulsivity in PD patients as compared to healthy controls. Twenty-one psychotropic drug-naive PD outpatients and 20 healthy subjects matched by age and sex were examined. Cognitive decision-making and risk-taking behaviour was measured with CGT (Cambridge Gambling Task) from CANTAB battery. The PD severity was assessed with Panic and Agoraphobia Scale (PAS). The level of anxiety and depression was assessed with HADS (Hospital Anxiety and Depression Scale). Impulsivity was evaluated with the Barratt Impulsiveness Scale, 11(th) version (BIS-11). There were no statistically significant differences on CGT in PD patients as compared to healthy control. However, having observed more closely, there are some differences between patients and healthy control. PD patients with higher anxiety level in HADS exhibited lower percentages of risky decisions comparing to PD with lower anxiety in HADS. PD patients with higher depression level in HADS demonstrated slowed decision-making when compared to PD patients with low level of depression in HADS. Total impulsivity and its attentional and motor dimensions were significantly higher in panic disorder patients versus healthy controls. There were no statistically significant differences with regard to CGT assessed decision-making between drug-naive PD patients and healthy controls. The PD patients with higher HADS-D depression level demonstrated slowed decision-making as compared to PD patients with low level of depression.

    This report documents the scientific activities on board the Royal Research Ship (RRS) 'James Clark Ross' during the irst Atlantic Meridional Transect (AMT-1), 21 September to 24 October 1995. The ship sailed from Grimsby (England) for Montevideo (Uruguay) and then continued on to Stanley (Falkland Islands). The primary objective of the AMT program is to investigate basic biological processes in the open Atlantic Ocean over very broad spatial scales. For AMT-1, the meridional range covered was approximately 50 deg N to 50 deg S or nearly 8,000 nmi. The measurements to be taken during the AMT cruises are fundamental for the calibration, validation, and continuing understanding of remotely sensed observations of biological oceanography. They are also important for understanding plankton community structure over latitudinal scales and the role of the world ocean in global carbon cycles. During AMT-1 a variety of instruments were used to map the physical, chemical, and biological structure of the upper 200 m of the water column. Ocean color measurements were made using state-of-the-art sensors, whose calibration was traceable to the highest international standards. New advances in fluorometry were used to measure photosynthetic activity, which was then used to further interpret primary productivity. A unique set of samples and data were collected for the planktonic assemblages that vary throughout the range of the transect. These data will yield new interpretations on community composition and their role in carbon cycling. While the various provinces of the Atlantic Ocean were being crossed, the partial pressure of CO2 was related to biological productivity. This comparison revealed the areas of drawdown of atmospheric CO2 and how these areas relate to the surrounding biological productivity. These data, plus the measurements of light attenuation and phytoplankton optical properties, will be used as a primary input for basin-scale biological productivity models to help

    The aim of this study was to perform a quantitative and qualitative assessment of pain in hospitalised teenagers suffering from neoplastic disease. Pain is a regular finding in patients with neoplasms and is classified according to its location, intensity, and type (character). Pain is a kind of stress that triggers mechanisms of psychological coping, interferes with activities of daily living, impairs social interactions, and adversely affects the psyche. The aim of this study was to examine the clinical and psychosocial context of pain in teenagers suffering from neoplastic disease. We examined 40 patients with neoplasms aged 12 to 20 years. We recorded the location, duration, intensity, and character of pain, the impact of pain on activities of daily living, and ways of coping with pain. The following scales were used: visual analog scale (VAS), numerical rating scale (NRS), activities of daily living scale, pain questionnaire, pain coping questionnaire. The results were analyzed statistically using quantitative, percentage, and rank tests. On the day of the examination, the patients reported pain in the lower limbs (27.5%), head (25%), and chest (17.5%). The intensity of pain was 5.75 on the VAS scale. Pain usually interfered with learning (4.22 on the 0-10 scale) and had a negative effect on mood (5.9 on the 0-10 scale). In describing their pain, the patients used words of the sensory (piercing, pulsating, shooting, stabbing) and emotional (tormenting, troublesome, disgusting) categories. The most common ways of coping with pain included: wishing that the pain disappeared (95% of children), telling parents about the pain (95%), asking for a drug (92.5%), and going to sleep (72.5%). The general health of the patients was established on the basis of the Karnofsky scale index which showed that 57.5% of them were in the upper and 42.5% were in middle categories of health. All patients experienced pain which was chiefly the side-effect of chemotherapy and the

    This report supplements the Preliminary Safety Analysis Report: Centrifuge Plant Demonstration Facility, Building K-1220, K/D-3924 (Draft), by (1) replying to detailed comments from Oak Ridge Operations (ORO) of the Department of Energy (DOE), (2) incorporating additional information, (3) reproducing a revised version of an earlier memo that addresses several important safety issues, and (4) including a revised list of general and specific safety criteria, safety definitions, and safety systems. The last item, and this supplement as a whole, reflects a revised view of which elements of a facility should be emphasized in a preliminary safety analysis report (PSAR). The original PSAR for the Centrifuge Plant Demonstration Facility (CPDF) was written to include capital equipment loss as a safety concern; this supplement views capital equipment loss as a safety concern only when such loss could affect the health and safety of the public or employees. Several of the detailed comments are answered by a reference to K/O-4036. The more important safety information, besides that given in the memo in Appendix A, is to be found in the replies to comments. It should be emphasized that this supplement, like the original CPDF PSAR, is a preliminary report prepared before the design was complete. In the judgment of the CPDF operating contractor, the conclusion stated in the summary chapter of the PSAR is still valid - the facility can be operated with no significant impact on the health and safety of the public and employees.

    From June 18 to July 17, 1997, the NRC Twin Otter atmospheric research aircraft was operated from Oklahoma City, U.S.A., in the Southern Great Plains 1997 (SGP97) Hydrology Experiment. The primary role of the aircraft was to measure the vertical fluxes of sensible and latent heat, CO2, ozone and momentum in the atmospheric boundary layer, along with supporting meteorological and radiometric data. Approximately 400 flux runs and 100 soundings were flown in 27 project flights over rural areas near Oklahoma City. This preliminary report documents the flight program, lists the instrumentation aboard the aircraft, and presents a summary of run-averaged data from each flux run. These data are from the in-field analysis and must be considered preliminary. A re-analysis incorporating updated calibrations is planned for the fall of 1997 followed by a more comprehensive technical report.

    Under contract with the City of Brentwood and auxiliary support by the East Contra Costa Irrigation District (ECCID), a preliminary research assessment of the groundwater resources beneath the Brentwood region is complete. The research was performed by an isotope geochemistry approach rather than traditional hydrogeological methods. The isotope approach is inexpensive relative to the traditional methods and has been used here mostly as a tracer that details the source, migration paths, and migration rates of existing groundwater supplies. In addition, the isotope results provide a quantitative framework in which to answer questions important to Brentwood including: (1) What is the long-term and short-term sustainability of the groundwater resources relative to current urban growth projections? (2) How can the good water quality be maximized in groundwater wells under short and long-term groundwater use schemes? (3) What underground areas exist within the Brentwood region that indicate untapped groundwater supplies that may provide plentiful, good quality water? This preliminary report focuses only on the first question. The second and third questions will be addressed in the final report to be completed by January 1, 1995. Furthermore, the conclusions in this preliminary report of how much groundwater is available for use will be incorporated into the Groundwater Management Plan currently being developed by the ECCID in conjunction with the City of Brentwood.

    A master plan for the Yakima/Klickitat Production Project (YKPP) was developed by the Northwest Power Planning Council (Council) on October 15, 1987, as a reasonable basis upon which the Bonneville Power Administration (BPA) could proceed to fund predesign work on the project. The Council approved the predesign work on the condition that eight preliminary tasks were completed. These tasks are: Agreement on a refined statement of project goals. Completion of a technical analysis of water supplies. Completion of an experimental design plan. Development of a harvest management plan. Assessment of potential genetic risks. Project coordination with all other affected parties. Submission of a preliminary design report to the Council. Develop a project management structure. The preliminary design report summarizes the work completed on these tasks. It provides a description of the preliminary design, engineering, and construction phases of project development, and gives an estimate of project costs. Also included is a description of other studies that were conducted to support YKPP planning. The results of studies conducted during the last 30 months indicate that hatchery facilities can be built in the Yakima and Klickitat subbasins to provide harvest benefits and to supplement natural production. Planning for the Yakima subbasin is at a more advanced stage of development than for the Klickitat subbasin because of greater availability of basic resource information. The information needed to proceed with final design and construction for the Klickitat subbasin will be available by 1992, as ongoing predesign work continues. This schedule is consistent with the anticipated phased completion of the YKPP by 1997.

    The purpose of this study was to evaluate potential technical advantages of the CO2 laser technology in mini-open transforaminal lumbar interbody fusion (TLIF) surgeries and report our preliminary clinical data on the safety and clinical outcomes. There is currently no literature discussing the recently redeveloped CO2 laser technology application for lumbar fusion. Safety and clinical outcomes were compared between two groups: 24 patients that underwent CO2 laser-assisted one-level TLIF surgeries and 30 patients that underwent standard one-level TLIF surgeries without the laser. There were no neural thermal injuries or other intraoperative laser-related complications encountered in this cohort of patients. At a mean follow-up of 17.4 months, significantly reduced lower back pain scores (P=0.013) were reported in the laser-assisted patient group compared to a standard fusion patient group. Lower extremity radicular pain intensity scores were similar in both groups. Laser-assisted TLIF surgeries showed a tendency (P = 0.07) of shorter operative times that was not statistically significant. Based on this preliminary clinical report, the safety of the CO2 laser device for lumbar fusion surgeries was assessed. There were no neural thermal injuries or other intraoperative laser-related complications encountered in this cohort of patients. Further investigation of CO2 laser-assisted lumbar fusion procedures is warranted in order to evaluate its effect on clinical outcomes.

    To validate a preliminary version of a radiological lexicon (RadLex) against terms found in thoracic CT reports and to index report content in RadLex term categories. Terms from a random sample of 200 thoracic CT reports were extracted using a text processor and matched against RadLex. Report content was manually indexed by two radiologists in consensus in term categories of Anatomic Location, Finding, Modifier, Relationship, Image Quality, and Uncertainty. Descriptive statistics were used and differences between age groups and report types were tested for significance using Kruskal-Wallis and Mann-Whitney Test (significance level <0.05). From 363 terms extracted, 304 (84%) were found and 59 (16%) were not found in RadLex. Report indexing showed a mean of 16.2 encoded items per report and 3.2 Finding per report. Term categories most frequently encoded were Modifier (1,030 of 3,244, 31.8%), Anatomic Location (813, 25.1%), Relationship (702, 21.6%) and Finding (638, 19.7%). Frequency of indexed items per report was higher in older age groups, but no significant difference was found between first study and follow up study reports. Frequency of distinct findings per report increased with patient age (p < 0.05). RadLex already covers most terms present in thoracic CT reports based on a small sample analysis from one institution. Applications for report encoding need to be developed to validate the lexicon against a larger sample of reports and address the issue of automatic relationship encoding.

    Neuroleptic treatment of psychotic symptoms or agitated behavior in elderly patients diagnosed with dementia is associated with reduced efficacy and increased rates of neuroleptic-induced parkinsonism in comparison to younger patients with schizophrenia. We report the first study to examine the relationship between an in vivo measure of dopaminergic function, plasma homovanillic acid (pHVA), and ratings of psychosis, agitation, and parkinsonism before and after neuroleptic treatment in dementia patients. Pretreatment pHVA was significantly correlated with parkinsonian rigidity, with a trend observed with agitation and hostility. Though mean pHVA did not change during perphenazine treatment, intraindividual change in pHVA at day 15 was correlated with improvement in hostility, with a similar trend for improvement in agitation. These preliminary findings are consistent with reports associating dopaminergic function with agitated, but not psychotic, symptoms in patients diagnosed with dementia, and with a reduced responsivity of dopaminergic systems to neuroleptic treatment in these patients.

    There is a mismatch between results of clinical trials and the needs of patients. The Patient-Centered Outcomes Research Institute (PCORI) in the US will commission research that supports patients and providers of care to make informed decisions. The preliminary draft of a methodology report presented by PCORI contains methodological standards which researchers will have to take into account when applying for funds from PCORI. An innovative instrument, the "Translation Tool" has been introduced to judge the best match between a specific research question and the corresponding methods. The "Translation Tool" structures the necessary trade-offs (e.g. between validity, patient-centered endpoints, timeliness, and resources) in a transparent manner. This article summarizes the development, structure and content of the methodology report. (As supplied by publisher).

    Background Ophthalmology is unique in that its practitioners are exposed to a host of ergonomic (eg, indirect ophthalmoscopy), ergo-ophthalmologic (laser), infectious (adenovirus), and allergic (topical anesthetics) hazards. The purpose of this study is to provide a preliminary occupational health profile of Iranian ophthalmologists. Methods A comprehensive list of occupation-related entities was incorporated into a questionnaire, which was distributed among 350 ophthalmologist participants of the Annual Iranian Congress of Ophthalmology (November 2000, Tehran) and was mailed twice to the 1050 nation's registered ophthalmologists. Independent Samples t and chi-square tests were used to assess the relationships. Results One hundred sixty-two questionnaires were returned. The mean career time was 15.7 (range, 1-40) years. Twenty (12.3%) of the participants were women. The reported prevalences were as follows: history of infectious conjunctivitis, 49.4%; contact dermatitis, 43.2%; back pain, 80%; chronic headache, 54.9%; and laser or operating microscope-related visual disturbances, 15%. Psychological indispositions were reported by two thirds. Age and career time were inversely related to contact dermatitis, chronic headache, and stress-related problems (P < .05). Visual complaints were more prevalent in vitreoretina surgeons (P < .004). Psychosocial disorders were significantly more reported by women (P = .026; odds ratio = 4.4). Only 3% of participants reported to have none of the listed problems. Conclusion Our preliminary survey disclosed a high prevalence of diverse complaints from back and neck pain, contact dermatitis, visual disturbances, and infectious conjunctivitis to stress-related and psychosocial disorders among the participants. Younger age, being a woman, and vitreoretina practice were the complaints correlates. Due to the low response rate, uncertainty over the representativeness and coverage of the sample, and lack of control groups, the findings

    The U.S. Geological Survey is conducting a geologic and geophysical study of the northeastern United States outer continental shelf and the adjacent slope from Georges Bank to Cape Hatteras. The study also includes the adjacent coastal plain because it is a more accessible extension of the shelf. The total study area is about 324,000 sq km, of which the shelf and slope constitute about 181,000 sq km and the coastal plain constitutes 143,000 sq km. The shelf width ranges from about 30 km at Cape Hatteras to about 195 km off Raritan Bay and on Georges Bank. Analyses of bottom samples make it possible to construct a preliminary geologic map of the shelf and slope to a water depth of 2,000 m. The oldest beds cropping out in the submarine canyons and on the slope are of early ate Cretaceous age. Beds of Early Cretaceous and Jurassic age are present in deep wells onshore and probably are present beneath the shelf in the area of this study. Such beds are reported beneath the Scotian shelf on the northeast where they include limestone, salt, and anhydrite. Preliminary conclusions suggest a considerably thicker Mesozoic sedimentary sequence than has been described previously. The region is large; the sedimentary wedge is thick; structures seem favorable; and the hydrocarbon potential may be considerable.

    ABSTRACT This preliminary report sought to provide insight into the genetic diversity of human immunodeficiency virus drug resistance (HIVDR) in Jamaica. This was done by investigating the genetic diversity associated with drug resistance in pregnant women living with HIV attending antenatal clinics in Kingston, Jamaica. Blood samples were collected and viral RNA were extracted and analysed. The protease and reverse transcriptase (Pro-RT) genes were amplified using the nested polymerase chain reaction (PCR) method. Polymerase chain reaction amplicons were obtained for nine (56%) of 16 patients, of which five (55%) were antiretroviral (ARV) drug naïve and four (45%) were treatment experienced. Three minor protease inhibitor resistant-conferring mutations (A71AT, A71V, A71T) and five mutations conferring high to low-level resistance (K219EK, T69S, K103S, G190A and K103N) were detected in the RT region. More than 50% of the resistance mutations found were detected in ARV drug naïve individuals, implying that viruses are being transmitted with the ARV resistance. These preliminary results will inform the health practitioners of the level of drug resistance that is being transmitted as well as strengthen the need to initiate a national baseline survey on HIVDR in Jamaica.

    Utilizing audio-recorded psychoanalytic interviews of both patients and their analysts, group discussions of these interviews, and the application of questionnaires commonly used in psychotherapy research, the authors investigate the potential use of the Leuzinger-Bohleber methodology as an objective evaluative instrument to assess the quality of psychoanalytic treatment. Preliminary study results were obtained through interviews conducted with seven analysts and their respective patients, three of whom were treated with psychoanalysis (three or more sessions per week, for a duration of no less than one year) and four with psychotherapy (one or two sessions per week, for a duration of no less than one year). Patients were found to be eager to participate, and no adverse experiences were reported by analysts, patients or the research team. In addition to the interviews, further data were obtained through review of mailed-in questionnaires completed by 21 patients. The authors present both preliminary observations regarding the methodology as a whole, as well as the detailed results of one specific case subject treated with psychotherapy. Review of study findings supports the utilization of this methodology as an evaluative instrument which may ultimately advance current knowledge of the process and outcome of psychoanalytic treatment.

    The 72-acre active Modern Sanitation Landfill (MSL) is located in York (York County), Pennsylvania. MSL reportedly received hazardous waste from 1976 to 1979. Preliminary on-site groundwater sampling results have identified methylene chloride, 1,1-dichloroethane, 1,2-trans-dichloroethylene, toluene, ethylbenzene, benzene, and vinyl chloride. Preliminary off-site surface water sampling results have identified methylene chloride, 1,1,1-trichloroethane, 1,1-dichloroethane, trichloroethylene (TCE), and cadmium. In addition, TCE was identified in off-site groundwater. The site is considered to be of potential public health concern because of the risk to human health caused by the possibility of human exposure to hazardous substances. Direct contact with and ingestion of contaminated groundwater and surface water are the exposure pathways of concern. In addition, direct contact with contaminated sediment and soils, inhalation of volatilized contaminants, and ingestion of bioaccumulated contaminants in the fish may be other possible environmental pathways. Additional information on contaminants released, populations potentially exposed, and environmental pathways through which the contaminants can reach these populations is necessary.

    The first Euromet expedition to the Frontier Mountain in Antarctica in December 1990 recovered two ureilites, FRO 90036 (34.6g) and FRO 90054 (17.5g). Preliminary classification indicated that the specimens had very different textures and mineral chemistries, and hence were not paired. A third ureilite, Acfer 277 (41.0 g), has also recently been returned from the Sahara. Due to the small sample sizes of the meteorites, and the unusual mineralogy of FRO 90054, a consortium was established to ensure the most effective study of these samples; this abstract reports on the carbon and nitrogen stable isotope geochemistry of two of the three ureilites issued to the consortium.

    On August 13, 2004, at approximately 3:45 p.m. EDT, Hurricane Charley made landfall at Cayo Costa, a Gulf of Mexico barrier island west of Cape Coral, Florida, as a Category 4 storm, with sustained winds estimated at 145 mph. Charley was the strongest hurricane to make landfall in the United States since Hurricane Andrew in August 1992. Charley created a 7-foot storm surge in Fort Myers, then traversed the state in 9 hours, continuing in a northeast direction across eight counties. This report presents preliminary data from Florida medical examiners (MEs), which indicated that 31 deaths were associated with Hurricane Charley. Deaths might be reduced through coordinated hurricane planning, focused evacuations, and advance communication to the public regarding the environmental hazards after a natural disaster.

    Stigma associated with behavioral health problems in the military pose challenges to accurate base rate estimations. Recent work has highlighted the importance of anonymous assessment methods, yet no study to date has assessed the ability of anonymous self-report measures to mitigate the impact of stigma on honest reporting. This study used the unmatched count technique (UCT), a form of randomized response techniques, to gain information about the accuracy of base rate estimates of alcohol misuse derived via anonymous assessment of Operation Enduring Freedom/Operation Iraqi Freedom active duty service members. A cross-sectional, convenience sample of 184 active-duty service members, recruited via online websites for military populations, provided data on two facets of alcohol misuse (drinking more than intended and feeling the need to reduce use) via traditional self-report and the UCT. The UCT revealed significantly higher rates relative to traditional anonymous assessment for both drinking more than intended (51.9% vs. 23.4%) and feeling the need to reduce use (39.3% vs. 18.2%). These data suggest that anonymity does not completely mitigate the impact of stigma on endorsing behavioral health concerns in the military. Our results, although preliminary, suggest that published rates of alcohol misuse in the military may underestimate the true rates of these concerns. The UCT has significant potential to improve base rate estimation of sensitive behaviors in the military.

    This report presents preliminary operational guidelines and supporting work products developed through the interagency Operational Guidelines Task Group (OGT). The report consolidates preliminary operational guidelines, all ancillary work products, and a companion software tool that facilitates their implementation into one reference source document. The report is intended for interim use and comment and provides the foundation for fostering future reviews of the operational guidelines and their implementation within emergency preparedness and response initiatives in the event of a radiological dispersal device (RDD) incident. The report principally focuses on the technical derivation and presentation of the operational guidelines. End-user guidance providing more details on how to apply these operational guidelines within planning and response settings is being considered and developed elsewhere. The preliminary operational guidelines are categorized into seven groups on the basis of their intended application within early, intermediate, and long-term recovery phases of emergency response. We anticipate that these operational guidelines will be updated and refined by interested government agencies in response to comments and lessons learned from their review, consideration, and trial application. This review, comment, and trial application process will facilitate the selection of a final set of operational guidelines that may be more or less inclusive of the preliminary operational guidelines presented in this report. These and updated versions of the operational guidelines will be made available through the OGT public Web site (http://ogcms.energy.gov) as they become finalized for public distribution and comment.

  12. The self-report Dissociative Disorders Interview Schedule: A preliminary report.

    A self-report version of the Dissociative Disorders Interview Schedule (SR-DDIS) was administered to 100 inpatients in a hospital-based trauma program. All participants had previously completed the interviewer-administered version of the DDIS. When we compared the overall results on the DDIS and SR-DDIS for the 100 inpatients, the findings were very consistent for both symptom clusters and Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), diagnoses. The agreement rate between the 2 versions for DSM-5 diagnoses was fair to substantial using Cohen's kappa, with agreement being substantial for 4 out of the 7 diagnoses made by the DDIS. It appears likely that the SR-DDIS can be used instead of the DDIS, at least in clinical populations, with no clinically or conceptually significant differences between the results obtained with the 2 versions.

    Background: Nasal airway obstruction (NAO) is a common health condition impacting mood, energy, recreation, sleep, and overall quality of life. Nasal surgery often addresses NAO but the results are sometimes unsatisfactory. Evaluating surgical treatment efficacy could be improved if objective tests were available that correlated with patient-reported measures of symptoms. The goal of this study was to develop methods for comparing nasal resistance computed by computational fluid dynamics (CFD) models with patient-reported symptoms of NAO using early data from a 4-year prospective study. Methods: Computed tomography (CT) scans and patient-reported scores from the Nasal Obstruction Symptom Evaluation (NOSE) scale and a visual analog scale (VAS) measuring unilateral airflow sensation were obtained pre- and postoperatively in two NAO patients showing no significant mucosal asymmetry who were successfully treated with functional nasal surgery, including septoplasty. Pre- and postsurgery CFD models were created from the CT scans. Numerical simulation of steady-state inspiratory airflow was used to calculate bilateral and unilateral CFD-derived nasal resistance (CFD-NR). Results: In both subjects, NOSE and VAS scores improved after surgery, bilateral CFD-NR decreased, and unilateral CFD-NR decreased on the affected side. In addition, NOSE and VAS scores tracked with unilateral CFD-NR on the affected side. Conclusion: These preliminary results suggest a possible correlation between unilateral NR and patient-reported symptoms and imply that analysis of unilateral obstruction should focus on the affected side. A formal investigation of unilateral CFD-NR and patient-reported symptoms in a series of NAO patients is needed to determine if these variables are correlated. PMID:22643935

    1993-08-01

    This report presents the results of the preliminary assessment (PA) conducted by Argonne National Laboratory at the Alaska Army National Guard property known as Camp Carroll Training Center, located on the Fort Richardson Army facility near Anchorage, Alaska. Preliminary assessments of federal facilities are being conducted to compile the information necessary for the completion of preremedial activities and to provide a basis for establishing, corrective actions in response to releases of hazardous substances. The principal objective of the PA is to characterize the site accurately and determine the need for further action by examining site activities, types and quantities of hazardous substances used, the nature and amounts of wastes generated or stored at the facility, and potential pathways by which contamination could affect public health and the environment. The primary environmentally significant operations (ESOs) associated with the property are (1) the Alaska Air National Guard storage area behind Building S57112 (Organizational Maintenance Shop [OMS] 6); (2) the state of Alaska maintenance facility and the soil/tar-type spill north of the state of Alaska maintenance facility; (3) the waste storage area adjacent to OMS 6; (4) the contaminated area from leaking underground storage tanks (USTs) and the oil-water separator; and (5) soil staining in the parking area at the Camp Carroll Headquarters Building. Camp Carroll appears to be in excellent condition from an environmental standpoint, and current practices are satisfactory. Argonne recommends that the Alaska Department of Military Affairs consider remediation of soil contamination associated with all storage areas, as well as reviewing the practices of other residents of the facility. Argonne also recommends that the current methods of storing waste material behind Building S57112 (OMS 6) be reviewed for alternatives.

    Pain is one of the most common and devastating symptoms in cancer patients, and misunderstandings on the patient's part can cause major obstacles in pain management. We evaluated factors associated with patient's high barrier score to managing cancer-associated pain by having 201 patients complete the Korean Barriers Questionnaire II, the Brief Pain Inventory--Korean, the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30, and the Korean Beck Depression Inventory. The Pain Management Index (PMI) was also assessed. The patients were from nine oncology clinics in university hospitals and a veterans' hospital in South Korea. The median pain score (0-10 scale) was 4, with a median percentage of pain improvement during the last 24 h of 70 %. A total of 150 patients (75 %) received strong opioids, and 177 (88 %) achieved adequate analgesia (positive PMI). Mean scores ± SD for the Barriers Questionnaire II ranged from 1.5 ± 1 to 2.8 ± 1.1, with the harmful effects subscale the highest. In the multiple regression model, depression was significantly associated with total barrier score to pain management (p < 0.0001). Pain reduction was significantly associated with the fatalism subscale. Depression was associated with high barrier score in patients with cancer pain. Management of cancer pain should include screening for depression, and management of depression could reduce patient-reported barriers to pain management.

  4. [Azithromycin: an anti-inflammatory effect in chronic recurrent multifocal osteomyelitis? A preliminary report].

    PubMed

    Schilling, F; Wagner, A D

    2000-10-01

    In this preliminary communication we report our experience with Azithromycin in patients with Chronic Recurring Multifocal Osteomyelitis (CRMO). Seven out of 13 patients, mainly teenager, showed a fast clinical improvement after they were started on Azithromycin. The immediate therapeutic effect of Azithromycin in patients with CRMO was surprising and lead us to the hypothesis that Azithromycin could have an antiphlogistic in addition to it's antibiotic effect in this disease setting. In patients with reactive chronic pelvic osteomyelitis Azithromycin obviously had a direct influence on the sympathic coxitis. Half of the patients reported an immediate reduction of pain and a significant improvement in range of movement after they were started on Azithromycin. In all cases the clinical and radiographic signs on MRI showed a reduction of the inflammatory process. Experimental animal models have recently shown that macrolids have independent additional antiinflammatory and immunomodulatory effects. The assumed local immunomodulatory effect of Azithromycin potentially is an additional activity to the already known synergistic antimicrobial and antiinflammatory effect. Right now we are in the process of collecting data from patients with SAPHO Syndrome who underwent bone-biopsies for microbiologic and histomorphologic investigations. All patients with the growth of propionibacterium acnes were started on a long-term antibiotic therapy with Azithromycin. This study will possibly help to answer the question of the additional antiphogistic/immunomodulatory effect of Azithromycin in this disease entity and the related CRMO.

    Background and aims Multiplayer Online Battle Arena (MOBA) games have become the most popular type of video games played worldwide, superseding the playing of Massively Multiplayer Online Role-Playing Games and First-Person Shooter games. However, empirical studies focusing on the use and abuse of MOBA games are still very limited, particularly regarding impulsivity, which is an indicator of addictive states but has not yet been explored in MOBA games. In this context, the objective of the present study is to explore the associations between impulsivity and symptoms of addictive use of MOBA games in a sample of highly involved League of Legends (LoL, currently the most popular MOBA game) gamers. Methods Thirty-six LoL gamers were recruited and completed both experimental (Single Key Impulsivity Paradigm) and self-reported impulsivity assessments (s-UPPS-P Impulsive Behavior Scale, Barratt Impulsiveness Scale), in addition to an assessment of problematic video game use (Problematic Online Gaming Questionnaire). Results Results showed links between impulsivity-related constructs and signs of excessive MOBA game involvement. Findings indicated that impaired ability to postpone rewards in an experimental laboratory task was strongly related to problematic patterns of MOBA game involvement. Although less consistent, several associations were also found between self-reported impulsivity traits and signs of excessive MOBA game involvement. Conclusions Despite these results are preliminary and based upon a small (self-selected) sample, the present study highlights potential psychological factors related to the addictive use of MOBA games.

    2004-11-01

    Some juveniles who engage in sexual offenses may have a paraphilia, a psychiatric disorder characterized by a pervasive pattern of deviant and impairing sexual fantasies, thoughts, and/or behaviors. Though there is no known cure for these conditions, paraphilias can be effectively managed using a multimodal treatment approach. This may include the use of psychotherapeutic and pharmacological treatment interventions, including antiandrogen medications. One such agent, leuprolide acetate (leuprolide), a luteinizing hormone-releasing-hormone agonist, has been shown to be effective in reducing paraphilic symptoms in adult patients. To date, however, there is no published data on its use and effectiveness in adolescent and young adult paraphilic patients. This study consists of a case report series of six young adult patients treated with leuprolide. All subjects had been diagnosed with at least one paraphilia (i.e., Pedophilia, Sexual Sadism, Frotteurism, and Paraphilia Not Otherwise Specified). All subjects had been refractory to treatment in a residential program for adolescent sex offenders prior to initiation of leuprolide. All six subjects reported a reduction in sexually deviant symptoms following treatment with leuprolide. Clinicians rated four as much improved and two as moderately improved. The treatment was well tolerated in all six subjects. This preliminary case series supports the conclusion that leuprolide deserves further examination as a potentially safe and effective component in the treatment of young adult patients with paraphilia.

    Many efforts have been made to create new diagnostic technologies for use in the diagnosis of central nervous system injury. However, there is still no consensus for the use of biomarkers in clinical acute spinal cord injury (SCI). The aims of this review are (1) to evaluate the current status of neurochemical biomarkers and (2) to discuss their potential acute diagnostic role in SCI by reviewing the literature. PubMed (http://www.ncbi.nlm.nih.gov/pubmed) was searched up to 2012 to identify publications concerning diagnostic biomarkers in SCI. To support more knowledge, we also checked secondary references in the primarily retrieved literature. Neurofilaments, cleaved-Tau, microtubule-associated protein 2, myelin basic protein, neuron-specific enolase, S100β, and glial fibrillary acidic protein were identified as structural protein biomarkers in SCI by this review process. We could not find reports relating ubiquitin C-terminal hydrolase-L1 and α-II spectrin breakdown products, which are widely researched in other central nervous system injuries. Therefore, we present our preliminary data relating to these two biomarkers. Some of biomarkers showed promising results for SCI diagnosis and outcome prediction; however, there were unresolved issues relating to accuracy and their accessibility. Currently, there still are not many reports focused on diagnostic biomarkers in SCI. This fact warranted the need for greater efforts to innovate sensitive and reliable biomarkers for SCI.

    Stigma associated with disclosing military sexual trauma (MST) makes estimating an accurate base rate difficult. Anonymous assessment may help alleviate stigma. Although anonymous research has found higher rates of male MST, no study has evaluated whether providing anonymity sufficiently mitigates the impact of stigma on accurate reporting. This study used the unmatched count technique (UCT), a form of randomized response techniques, to gain information about the accuracy of base rate estimates of male MST derived via anonymous assessment of Operation Enduring Freedom (OEF)/Operation Iraqi Freedom (OIF) combat veterans. A cross-sectional convenience sample of 180 OEF/OIF male combat veterans, recruited via online websites for military populations, provided data about history of MST via traditional anonymous self-report and the UCT. The UCT revealed a rate of male MST more than 15 times higher than the rate derived via traditional anonymous assessment (1.1% vs. 17.2%). These data suggest that anonymity does not adequately mitigate the impact of stigma on disclosure of male MST. Results, though preliminary, suggest that published rates of male MST may substantially underestimate the true rate of this problem. The UCT has significant potential to improve base rate estimation of sensitive behaviors in the military.

    Objective This paper provides a preliminary report of a music-based training program for adult cochlear implant (CI) recipients. Included in this report are descriptions of the rationale for music-based training, factors influencing program development, and the resulting program components. Methods Prior studies describing experience-based plasticity in response to music training, auditory training for persons with hearing impairment, and music training for cochlear implant recipients were reviewed. These sources revealed rationales for using music to enhance speech, factors associated with successful auditory training, relevant aspects of electric hearing and music perception, and extant evidence regarding limitations and advantages associated with parameters for music training with CI users. This information formed the development of a computer-based music training program designed specifically for adult CI users. Results Principles and parameters for perceptual training of music, such as stimulus choice, rehabilitation approach, and motivational concerns were developed in relation to the unique auditory characteristics of adults with electric hearing. An outline of the resulting program components and the outcome measures for evaluating program effectiveness are presented. Conclusions Music training can enhance the perceptual accuracy of music, but is also hypothesized to enhance several features of speech with similar processing requirements as music (e.g., pitch and timbre). However, additional evaluation of specific training parameters and the impact of music-based training on speech perception of CI users are required. PMID:26561884

Included in this report are descriptions of the rationale for music-based training, factors influencing program development, and the resulting program components. Prior studies describing experience-based plasticity in response to music training, auditory training for persons with hearing impairment, and music training for CI recipients were reviewed. These sources revealed rationales for using music to enhance speech, factors associated with successful auditory training, relevant aspects of electric hearing and music perception, and extant evidence regarding limitations and advantages associated with parameters for music training with CI users. This informed the development of a computer-based music training program designed specifically for adult CI users. Principles and parameters for perceptual training of music, such as stimulus choice, rehabilitation approach, and motivational concerns were developed in relation to the unique auditory characteristics of adults with electric hearing. An outline of the resulting program components and the outcome measures for evaluating program effectiveness are presented. Music training can enhance the perceptual accuracy of music, but is also hypothesized to enhance several features of speech with similar processing requirements as music (e.g., pitch and timbre). However, additional evaluation of specific training parameters and the impact of music-based training on speech perception of CI users is required.

    This pamphlet contains a complete list of all maps and reports issued by the Geologic Branch and Alaskan Branch of the Geological Survey whose release was announced by press notice during the period between January 1, 1938 and January 1, 1945. The Geologic Branch material was compiled by Lois S. Kent, and the Alaskan Branch material by R. P. Kerocher. It is expected that similar lists will be published annually hereafter. These reports and maps are the results of work carried out by Survey geologists on mineral deposits in the United States, Alaska, and Cuba during the war and the years immediately preceding the war. They were released in preliminary form as rapidly as possible in this period to avoid the delays necessarily attendant upon formal publication and to make the information contained in them promptly available to property owners and mine operators concerned with the production of strategic and critical mineral commodities.

    The radiological, fire and electrical hazards posed by a 200 MeV electron Linear Accelerator, which the NSLS Department will install and commission within a newly assembled structure, are addressed in this Preliminary Safety Analysis Report. Although it is clear that this accelerator is intended to be the injector for a future experimental facility, we address only the Linac in the present PSAR since neither the final design nor the operating characteristics of the experimental facility are known at the present time. The fire detection and control system to be installed in the building is judged to be completely adequate in terms of the marginal hazard presented - no combustible materials other than the usual cabling associated with such a facility have been identified. Likewise, electrical hazards associated with power supplies for the beam transport magnets and accelerator components such as the accelerator klystrons and electron gun are classified as marginal in terms of potential personnel injury, cost of equipment lost, program downtime and public impact perceptions as defined in the BNL Environmental Safety and Health Manual and the probability of occurrence is deemed to be remote. No unusual features have been identified for the power supplies or electrical distribution system, and normal and customary electrical safety standards as practiced throughout the NSLS complex and the Laboratory are specified in this report. The radiation safety hazards are similarly judged to be marginal in terms of probability of occurrence and potential injury consequences since, for the low intensity operation proposed - a factor of 25 less than the maximum Linac capability specified by the vendor - the average beam power is only 0.4 watts. The shielding specifications given in this report will give adequate protection to both the general public and nonradiation workers in areas adjacent to the building as well as radiation workers within the controlled access building.

    Obstructive sleep apnea (OSA) in children, characterized by hypoventilation secondary to upper airway obstruction, often results from tonsil and adenoid hypertrophy. Adenotonsillectomy is the standard therapy in this patient population. The immediate postoperative period is complicated occasionally by respiratory difficulties that may require intubation and mechanical ventilation. Recently, physicians have provided temporary airway support using continuous and bilevel positive airway pressure (BiPAP) devices. Reported complications of positive airway pressure devices include local abrasions to the nose and mouth; dryness of the nose, eyes, and mouth; sneezing; nasal drip, bleeds, and congestion; sinusitis; increased intraocular pressure; non-compliance; and pneumocephalus. Subcutaneous emphysema following facial trauma, dental extractions, adenotonsillectomy, and sinus surgery has been reported. There is also a hypothetically increased risk of subcutaneous emphysema following the use of positive airway pressure ventilation in the tonsillectomy patient. Between January 1997 and July 1998, 1321 patients underwent tonsillectomy and/or adenoidectomy at our institution. In reviewing the records of all pediatric intensive care unit admissions during that time period, we identified nine patients, of the 1321, who required BiPAP postoperatively. Of these, four children were obese, four had preexisting neurological disorders, and one underwent endoscopic sinus surgery and adenoidectomy. Three children were asthmatic, and three were less than 3 years of age. Two obese children were discharged with home BiPAP, one of whom had been on BiPAP prior to surgery. All patients tolerated BiPAP without complications. This preliminary report suggests that BiPAP is a safe and effective method of respiratory assistance in the adenotonsillectomy patient with preexisting conditions who is predisposed to postoperative airway obstruction. Furthermore, with BiPAP, the risks of intubation and

    The utilization of spinal cord stimulation (SCS) to treat intractable pain has increased substantially in recent years. Integral to this therapy, the fluoroscope assists with requisite mapping protocols during trialing procedures to identify topographical dermatomal representations of spinal segments, and its use demands measurements of radiation exposure. However, such data is not found in the literature. The aim of this study was to report on radiation exposure during percutaneous SCS trialing procedures. An observational study. A non-university out-patient Interventional Pain Management practice in the United States. Fluoroscopy time from 110 SCS trialing procedures performed in a non-university, outpatient setting was studied retrospectively. Summary statistics were reported for all procedures collectively, as well as for lead arrangement and location. The interventional spine team carried out all procedural cases with the same mobile C-arm fluoroscopy system. Incident air kerma was evaluated by simplistic modeling. Mean total fluoroscopy time was 133.4 s with a standard deviation of 84.8 s, and the mean percentage of time allocated to pulsed fluoroscopy was 31.9%. Fluoroscopy time for the most common lead arrangement/location, neural canal dual leads/low-thoracic (n=87), ranged from 28.5 s to 387.4 s. Incident air kerma was 1.8-43.7 mGy. A preliminary report with a sample size of 110. Various lead placement options are available to the spinal interventionalist to treat pain with SCS. Our data set provides first steps to obtain benchmark reference estimates on fluoroscopy times and radiation exposure during SCS trialing procedures/spinal segment mapping. Fluoroscopy times for such interventions may be considerable when compared to more commonly performed pain medicine procedures; however, skin injury is improbable.

    2012-03-01

    A new onsite, remote-handled low-level waste disposal facility has been identified as the highest ranked alternative for providing continued, uninterrupted remote-handled low-level waste disposal for remote-handled low-level waste from the Idaho National Laboratory and for nuclear fuel processing activities at the Naval Reactors Facility. Historically, this type of waste has been disposed of at the Radioactive Waste Management Complex. Disposal of remote-handled low-level waste in concrete disposal vaults at the Radioactive Waste Management Complex will continue until the facility is full or until it must be closed in preparation for final remediation of the Subsurface Disposal Area (approximately at the end of Fiscal Year 2017). This preliminary safety design report supports the design of a proposed onsite remote-handled low-level waste disposal facility by providing an initial nuclear facility hazard categorization, by discussing site characteristics that impact accident analysis, by providing the facility and process information necessary to support the hazard analysis, by identifying and evaluating potential hazards for processes associated with onsite handling and disposal of remote-handled low-level waste, and by discussing the need for safety features that will become part of the facility design.

  1. Remotely sensed indicators of habitat heterogeneity and biological diversity: A preliminary report

    The relationship between habitat area, spatial dynamics of the landscape, and species diversity is an important theme in population and conservation biology. Of particular interest is how populations of various species are affected by increasing habitat edges due to fragmentation. Over the last decade, assumptions regarding the effects of habitat edges on biodiversity have fluctuated wildly, from the belief that they have a positive effect to the belief that they have a clearly negative effect. This change in viewpoint has been brought about by an increasing recognition of the importance of geographic scale and a reinterpretation of natural history observations. In this preliminary report from an ongoing project, we explore the use of remote sensing technology and geographic information systems to further our understanding of how species diversity and population density are affected by habitat heterogeneity and landscape composition. A primary feature of this study is the investigation of SAR for making more rigorous investigations of habitat structure by exploiting the interaction between radar backscatter and vegetation structure and biomass. A major emphasis will be on the use of SAR data to define relative structural types based on measures of structural consolidation using the vegetation surface area to volume ratio (SA/V). Past research has shown that SAR may be sensitive to this form of structural expression which may affect biodiversity.

    Thermal ablation has been proved safe and effective as the treatment for liver tumors that are not suitable for resection. Currently, manually performed thermal ablation is greatly dependent on the surgeon's acupuncture manipulation against hand tremor. Besides that, inaccurate or inappropriate placement of the applicator will also directly decrease the final treatment effect. In order to reduce the influence of hand tremor, and provide an accurate and appropriate guidance for a better treatment, we develop an ultrasound-directed robotic system for thermal ablation of liver tumors. In this paper, we will give a brief preliminary report of our system. Especially, three innovative techniques are proposed to solve the critical problems in our system: accurate ultrasound calibration when met with artifacts, realtime reconstruction with visualization using Graphic Processing Unit (GPU) acceleration and 2D-3D ultrasound image registration. To reduce the error of point extraction with artifacts, we propose a novel point extraction method by minimizing an error function which is defined based on the geometric property of our N-fiducial phantom. Then realtime reconstruction with visualization using GPU acceleration is provided for fast 3D ultrasound volume acquisition with dynamic display of reconstruction progress. After that, coarse 2D-3D ultrasound image registration is performed based on landmark points correspondences, followed by accurate 2D-3D ultrasound image registration based on Euclidean distance transform (EDT). The effectiveness of our proposed techniques is demonstrated in phantom experiments.

    This is the preliminary report of a study to evaluate the effectiveness of the Chronic Disease Self-management Program in Japan by comparing changes in health outcomes at the baseline and 3-month and 6-month follow-ups. The program is a patient-centered educational program for the self-management of chronic conditions. The study's participants were recruited from among the attendees of the program workshops. During the study period (August 2006 to May 2007), 18 workshops were held and 128 attendees agreed to participate in the study. The health outcomes that were measured included health status, self-management behaviors, utilization of health services, self-efficacy, satisfaction with daily living, and clinical indicators. These indicators were further analyzed by disease type: diabetes, rheumatic disease, and cardiovascular disease/dyslipidemia. The findings indicated statistically significant positive changes in health distress, coping with symptoms, stretching exercises, communication with the physician, and satisfaction with daily living. The positive changes were especially remarkable among the groups with diabetes and rheumatic disease. These findings suggest that the Chronic Disease Self-management Program can be effective for Japanese people with chronic conditions. © 2010 Blackwell Publishing Asia Pty Ltd.

    A prospective review of surgical patients attending the Accident and Emergency room was carried out to determine the pattern of morbidity and mortality in order to guide planning and provision of surgical services and improve on the quality of care available. Patients were entered into a data sheet from September 1999; a preliminary report of the first six months is presented. There were 1,209 patients (850 males and 359 females, M:F = 2.2:1) with 46 different presentations. Age range was 2 weeks to 95 years. The mode and median age was in the third decade. Morbidity from trauma was 70.5%, 44.5% from Road Traffic Accident while mortality from trauma was 2.6% (32 patients). Nearly half of the mortality (47.2%) was head injury related. The commonest presentation was lacerations (19.4%) from which there was no mortality while head injury, multiple injury and multiple fractures that accounted for 14.7% morbidity had 61.1% mortality. These figures are helpful in planning services delivery and in focusing and improving on the mortality-prone presentations.

    Short leukocyte telomere length (LTL) may be associated with several psychiatric disorders, including major depressive disorder (MDD). Short LTL has previously been associated with poor response to psychiatric medications in bipolar disorder and schizophrenia, but no studies have prospectively assessed the relationship of LTL to SSRI response in MDD. We assessed pre-treatment LTL, depression severity (using the Hamilton Depression Rating Scale [HDRS]), and self-reported positive and negative affect in 27 healthy, unmedicated adults with MDD. Subjects then underwent open-label treatment with a selective serotonin reuptake inhibitor (SSRI) antidepressant for eight weeks, after which clinical ratings were repeated. Analyses were corrected for age, sex and BMI. "Non-responders" to treatment (HDRS improvement <50%) had significantly shorter pre-treatment LTL, compared to "Responders" (p=0.037). Further, shorter pre-treatment LTL was associated with less improvement in negative affect (p<0.010) but not with changes in positive affect (p=0.356). This preliminary study is the first to assess the relationship between LTL and SSRI response in MDD and among the first to prospectively assess its relationship to treatment outcome in any psychiatric illness. Our data suggest that short LTL may serve as a vulnerability index of poorer response to SSRI treatment, but this needs examination in larger samples.

    Twenty-one low-level liquid radioactive waste collection and storage tanks are part of approximately 76 facilities currently managed by the ORNL Surplus Facilities Management Program (SFMP). This program, as part of the DOE national SFMP, is responsible for the maintenance and surveillance and the final decommissioning of radioactively contaminated surplus ORNL facilities. A long range planning effort is being conducted that will outline the scope and objectives of the ORNL program and establish decommissioning priorities based on health and safety concerns, budget constraints, and other programmatic constraints. In support of this SFMP planning activity, preliminary engineering assessments are being conducted for each of the ORNL surplus facilities currently managed under the program. These efforts are designed to: (1) provide an initial assessment of the potential decommissioning alternatives; (2) choose a preferred alternative and provide a justification of the decommissioning plan, including cost and schedule estimates. D&D of eight of the nine groups of surplus tanks are considered in this report.

    1984-01-01

    The comparative corneal epithelial effects of rigid gas permeable and soft contact lenses are reported in the present preliminary study using two bush baby monkeys (Galago senegalensis). Both types of lenses produced early cell death among the surface squamous cells while internally the epithelium and its nerve fibers remained normal. Sporadically small abnormal groups of cells involving two to three of the surface layers were observed in both the hard and soft lens wearing corneas. It was concluded that this represented superficial punctate keratitis (SPK). Small superficial intracellular epithelial cysts with membranous contents were infrequently noted in the gas permeable lens wearing cornea and it is suggested here that they were mild forms or precursors of those seen clinically in human corneas. Since the gas permeable lens met the corneal oxygen requirement it is postulated that the traumatic effect of the rigidity of the lens caused the cystic formation to occur. The relative hypoxia induced by the soft contact lens resulted in a mild superficial epithelial edema.

    The Wedzeb Enterprises Inc. Site (WES) is listed on the National Priorities List. The site consists of 2 warehouses and is located in Lebanon (Boone County), Indiana. A fire destroyed a warehouse containing about 50,000 capacitors, and caused the release of polychlorinated biphenyls (PCBs) and low levels of dioxin and tetrachlorodibenzofuran (TCDF) into the area. Preliminary on-site 'fire debris' sampling results have identified PCBs (500 to 24,500 ppm), tetrachlorodibenzodioxin and TCDF (30 to 500 ppt). However, the sampling information reported was taken in 1981. Based on available information, the site is considered to be of potential public health concern because of the risk to human health caused by the possibility of human exposure to hazardous substances. Direct contact and ingestion with possibly contaminated ground water from private wells is the likely route of exposure. Direct contact with soils, sediment, surface water, and inhalation of volatilized contaminants or contaminants entrained in air by area residents and on-site workers are possible human exposure pathways that require further sampling information.

  9. The effect of ionization on the infrared absorption spectra of PAHs: A preliminary report

    1989-01-01

    The emission lines observed in many interstellar IR sources at 3.28, 6.2, 7.7, 8.7, and 11.3 microns are theorized to originate from polycyclic aromatic hydrocarbons (PAHs). These assignments are based on analyses of lab IR spectra of neutral PAHs. However, it is likely that in the interstellar medium that PAHs are ionized, i.e., are positively charged. Besides, as pointed out by Allamandola et al., although the IR emission band spectrum resembles what one might expect from a mixture of PAHs, it does not match in details such as frequency, band profile, or relative intensities predicted from the absorption spectra of any known PAH molecule. One source of more information to test the PAH theory is ab initio molecular orbital theory. It can be used to compute, from first principles, the geometries, vibrational frequencies, and vibrational intensities for model PAH compounds which are difficult to study in the lab. The Gaussian 86 computer program was used to determine the effect of ionization on the infrared absorption spectra of several small PAHs: naphthalene and anthracene. A preliminary report is presented of the results of these calculations.

    We used functional connectivity magnetic resonance imaging (fcMRI) to investigate changes in interhemispheric brain connectivity in 11 patients with mild Alzheimer’s disease (AD) following eight weeks of treatment with the cholinesterase inhibitor donepezil. We examined functional connectivity between four homologous temporal, frontal, and occipital regions. These regions were selected to represent sites of AD neuropathology, sites of donepezil-related brain activation change in prior studies, and sites that are minimally affected by the pathologic changes of AD. Based on previous findings of selective, localized frontal responses to donepezil, we predicted that frontal connectivity would be most strongly impacted by treatment. Of the areas we examined, we found that treatment had a significant effect only on functional connectivity between right and left dorsolateral prefrontal cortices. Implications for understanding the impact of donepezil treatment on brain functioning and behavior in patients with AD are discussed. This preliminary report suggests that fcMRI may provide a useful index of treatment outcome in diseases affecting brain connectivity. Future research should investigate these treatment-related changes in larger samples of patients and age-matched controls. PMID:22886013

    The chemical compositions of waters collected from the Cerro Prieto geothermal production wells and hydrothermal emanations are different. Compared to the Cerro Prieto well waters, the surficial waters generally contain significantly less potassium, slightly less calcium and chloride, and significantly more magnesium and sulfate. In comparison to the unaltered sediments, the changes in the mineralogy of the altered sediments appear to be controlled by the type of emanation (well, spring, mud pot, geyser, fumarole, or cold pool). However, an increase in quartz and potassium feldspar percentages seems to be characteristic of the majority of the sediments in contact with geothermal fluids. Preliminary attempts to model the chemical processes occurring in the Cerro Prieto geothermal field using chemical equilibrium calculations are reported. For this purpose the chemical compositions of thermal waters (well and surficial emanation) were used as input data to make calculations with SOLMNEQ and WATEQ2 computer programs. Then the theoretical mineral composition of altered sediments was predicted and compared to the mineralogy actually observed in the solid samples.

    Laser-assisted lithotripsy under sialendoscopy has the potential to overcome the limitations of traditional sialendoscopic lithotripsy when facing salivary stones. In this preliminary study, we report our experience with Holmium:YAG laser-assisted lithotripsy. Data from 11 Asian patients receiving sialendoscopies for laser-assisted lithotripsy performed in our department from August 2013 to June 2014 were recorded and reviewed. A total of 18 procedures were performed in 11 Taiwanese patients with symptoms of obstructive sialoadenitis who were diagnosed with sialolithiasis. The sizes of the stones ranged between 3 mm and 13 mm. The endoscopic lithotomy procedures were performed in all 11 patients, and stone fragmentation with the Holmium:YAG laser was done successfully in all patients. All patients were followed for a minimum of 3 months, and there was no evidence of complications or recurrences over the follow up period. The Holmium:YAG laser allowed successful fragmentation of stones in all 11 patients. Our experience with this procedure supports the use of Holmium:YAG laser-assisted lithotripsy through sialendoscopy in Asian patients.

    The ketogenic diet is increasingly used for the management of difficult-to-control seizures in children. Here, we describe the first prospective study of the effects of the diet on development, behavior, and parenting stress. Participants were 65 children (36 males, 29 females) with intractable seizures, ages 18 months to 14 years 6 months, enrolled in a prospective study at the Johns Hopkins Hospital, Baltimore, MD, USA, to study the diet's efficacy. Children were assessed before diet initiation and at 1-year follow-up. At follow-up, 52% (34 of 65) children remained on the diet. Mean seizure frequency decreased from 25 per day before diet initiation to less than two per day 1 year later. At follow-up, mean developmental quotient showed statistically significant improvement (p<0.05), with significant behavioral improvements in attention and social functioning. Parental stress was essentially unchanged. No baseline factor examined predicted diet adherence, and the primary reason for diet discontinuation was insufficient seizure control. These preliminary results support prior anecdotal reports of the beneficial effects of the diet on cognition and behavior.

    Purpose: This preliminary report describes the development and implementation of a project to improve access to literature in Latin American social medicine (LASM). Methods: The University of New Mexico project team collaborated with participants from Argentina, Brazil, Chile, and Ecuador to identify approximately 400 articles and books in Latin American social medicine. Structured abstracts were prepared, translated into English, Spanish, and Portuguese, assigned Medical Subject Headings (MeSH), and loaded into a Web-based database for public searching. The project has initiated Web-based publication for two LASM journals. Evaluation included measures of use and content. Results: The LASM Website (http://hsc.unm.edu/lasm) and database create access to formerly little-known literature that addresses problems relevant to current medicine and public health. This Website offers a unique resource for researchers, practitioners, and teachers who seek to understand the links between socioeconomic conditions and health. The project provides a model for collaboration between librarians and health care providers. Challenges included procurement of primary material; preparation of concise abstracts; working with trilingual translations of abstracts, metadata, and indexing; and the work processes of the multidisciplinary team. Conclusions: The literature of Latin American social medicine has become more readily available to researchers worldwide. The LASM project serves as a collaborative model for the creation of sustainable solutions for disseminating information that is difficult to access through traditional methods. PMID:14566372

    The current study investigated the reliability of a new self-report questionnaire assessing accountability for the perpetration of intimate partner violence. The Accountability Scale (AS) is a brief, Likert-type measure designed to assess the degree to which perpetrators acknowledge and accept responsibility for their violent actions. In Study #1, an exploratory factor analysis on a clinical sample revealed two factors: Acknowledging Harm and Internalizing Responsibility. In Study #2, the factor structure was replicated on a community sample using confirmatory factor analysis, revealing an 11-item solution. Factor 1 was related to readiness to change but negatively related to social desirability, suggesting convergent and discriminant validity of that subscale. Factor 2 was negatively related to Factor 1 in the community sample, calling into question the construct of accountability. Preliminary evidence suggests that the AS shows promise as a brief and reliable tool to assess forms of accountability. Future research will examine if the two factors of accountability function as mechanisms of change and outcome measures in intimate partner violence intervention research.

Subjects were 11 male and 12 female general aviation pilots, ages 21-40. Subjects received 8 h of training before they were tested with alcohol. On the alcohol test day they were tested before drinking, while intoxicated (target BAC of 0.08%), and 8 h after drinking. The average, observed peak BAC readings for men and women were within 0.003% of each other. We observed faster disappearance rates for women such that women reached the FAA cutoff of 0.04% approximately 1 h before men, on average. Compared to predrink performance, there was a significant decrement in simulator performance during acute intoxication, but not 8 h after drinking. There were no significant gender differences in performance before or after drinking alcohol. Slower rates of alcohol elimination were associated with larger performance changes 8 h after drinking. This is the first report to our knowledge suggesting a possible relation between alcohol elimination rate and change in performance after drinking alcohol. A 12.5% dose reduction for women appears to be adequate for achieving comparable peak BAC's for male and female groups. Future studies using measures of circadian rhythmicity in conjunction with pharmacokinetic and performance measures could potentially shed light on differences in subjects' acute and delayed responses to alcohol.

    Introduction Interaction of several genes is responsible for psychiatric diseases such as depression. Despite the numerous microarray studies in this field, findings are controversial and hard to conclude. Methods Male Wistar rats were randomly selected to receive Chronic Mild Stress model for 4 weeks. Different aspects of depression were measured by forced swimming test, open field trial and sucrose preference tests in the experience group and controls. Results Sucrose was preferred by 40% of CMS group and 80% of controls (p=0.025). Twenty percent of CMS group and 80% of controls were “active” (p=0.001). Last escape was at minute 238 for CMS group and minute 245 for controls and controls had more escape efforts. Conclusion This paper is a preliminary report of a genomic study on animal model of depression which tries to achieve reliable results by a joint of clinical view with recent techniques. Predicted challenges in this procedure and the solutions as well as the limitations may be helpful for future researches. PMID:23678424

    In response to reports of increasing financial and administrative burdens on oncology practices and a lack of systematic information related to these issues, American Society of Clinical Oncology (ASCO) leadership started an effort to collect key practice-level data from all oncology practices in the United States. The result of the effort is the ASCO National Census of Oncology Practices (Census) launched in June 2012. The initial Census work involved compiling an inventory of oncology practices from existing lists of oncology physicians in the United States. A comprehensive, online data collection instrument was developed, which covered a number of areas, including practice characteristics (staffing configuration, organizational structure, patient mix and volume, types of services offered); organizational, staffing, and service changes over the past 12 months; and an assessment of the likelihood that the practice would experience organizational, staffing, and service changes in the next 12 months. More than 600 practices participated in the Census by providing information. In this article, we present preliminary highlights from the data gathered to date. We found that practice size was related to having experienced practice mergers, hiring additional staff, and increasing staff pay in the past 12 months, that geographic location was related to having experienced hiring additional staff, and that practices in metropolitan areas were more likely to have experienced practice mergers in the past 12 months than those in nonmetropolitan areas. We also found that practice size and geographic location were related to higher likelihoods of anticipating practice mergers, sales, and purchases in the future.

    To profile training habits and injuries in football players participating in a national Masters tournament. A cross-sectional retrospective study design was used to survey male football players attending the 2008 New Zealand Masters Games. Information regarding player demographics, football injuries, football related training, and risk factors for injury were collected. 199 Players were recruited, with a median age of 44 yrs (range 35-73) and a median football playing history of 15 yrs (range 0-66). Irrespective of age, 112 (84%) players included a warm-up and 104 (78%) included a stretching regime in their regular training programme. In the 12 months prior to the tournament, 128 football related injuries were reported by 93 players (64 injuries/100 players or 46 injured players/100 players). The most frequently injured region was the lower limb; specifically the lower leg (n=23), ankle (n=18), hamstring (n=17), knee (n=15), and Achilles tendon (n=15). This study provides a preliminary insight into the training habits and injury profiles of Masters football players. Despite all players including some form of injury prevention strategy in their training, a significant number of players experienced an injury in the 12 months prior to the tournament.

    The first field tests in preparation for the NASA Global Positioning System (GPS) Caribbean Initiative were conducted in late March and Early April of 1985. The GPS receivers were located at the POLARIS Very Long Base Interferometry (VLBI) stations at Westford, Massachusetts; Richmond, Florida; and Ft. Davis, Texas; and at the Mojave, Owens Valley, and Hat Creek VLBI stations in California. Other mobile receivers were placed near Mammoth Lakes, California; Pt. Mugu, California; Austin, Texas; and Dahlgren, Virginia. These sites were equipped with a combination of GPS receiver types, including SERIES-X, TI-4100 and AFGL dual frequency receivers. The principal objectives of these tests were the demonstration of the fiducial network concept for precise GPS geodesy, the performance assessment of the participating GPS receiver types, and to conduct the first in a series of experiments to monitor ground deformation in the Mammoth Lakes-Long Valley caldera region in California. Other objectives included the testing of the water vapor radiometers for the calibration of GPS data, the development of efficient procedures for planning and coordinating GPS field exercise, the establishment of institutional interfaces for future cooperating ventures, the testing of the GPS Data Analysis Software (GIPSY, for GPS Inferred Positioning SYstem), and the establishment of a set of calibration baselines in California. Preliminary reports of the success of the field tests, including receiver performance and data quality, and on the status of the data analysis software are given.

    Sediments from Pass Key core 37, in eastern Florida Bay (N 25.1478?, W 80.5745?) record a history of rapid sedimentation during this century. The lowest portion of the core contains benthic fauna indicative of relatively low salinities and sparse seagrass coverage. This period is followed by an increase in salinity and seagrass. In the middle portion of the core, a slight decrease in salinity and an increase in seagrass occur. These shifts in the benthic fauna correspond to a period when the terrestrial flora change, and an increase in dinocyst absolute abundance occurs, indicating changes in factors affecting the entire South Florida ecosystem. These changes may represent a period of increased terrestrial flushing, due to rainfall, water management practices or a combination of both. The benthic faunas in the upper portion of the core indicate an increase in salinity and seagrass density. This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards or with the North American Stratigraphic Code.

    , thus supporting the disruptive data. On postoperative day 10, there was no difference in mean wound strength or mean tissue stiffness among any of the groups. These preliminary data represent the first report of in vivo, nondisruptive biomechanical characterization of linear incision wounds. The results suggest that through in vivo measurements of tissue stiffness, differences can be detected between treatment groups. Because the healing wound may be characterized without the need for disruption, this methodology should allow for consecutive, in vivo biomechanical testing of wounds in future wound healing studies.

    : The objective of this study was to pilot a new self-report screening instrument, the addictive behaviors questionnaire (ABQ), which screens for a broad range of impulsive-compulsive behaviors, in a treatment-seeking psychiatric population with comorbid addiction. : Psychiatric outpatients (N = 94) being treated for comorbid addiction and mental illness were approached consecutively by their therapists to fill out a number of self-report measures, in addition to the ABQ, including the Addiction Severity Index, Toronto Alexithymia Scale, and Reflective Activity Scale. The ABQ was evaluated both as a continuous measure and as a categorical measure using clinically relevant cutoff scores for each behavior. It was tested for internal reliability, test-retest reliability, and correlation with other scales. : The completion rate for the ABQ was 74%. It demonstrated good internal reliability (continuous measure α = 0.81, categorical measure alpha = 0.82) and good test-retest reliability (continuous r = 0.68, categorical r = 0.76). The total ABQ score positively correlated with alexithymia (continuous r = 0.45, P < 0.001; categorical r = 0.37, P < 0.001) and negatively correlated with reflective activity (continuous r = -0.29, P < 0.01; categorical r = -0.27, P < 0.05). The behaviors that were most commonly endorsed as problematic were overeating, unhealthy relationships, excessive TV watching, and excessive shopping. Based on cutoff scores, 61% of the sample endorsed at least one problematic behavior and 31% endorsed 2 or more behaviors. : These preliminary results suggest that the ABQ is reliable and easily administered by clinicians treating comorbid addiction in an outpatient setting. Further study is required with larger sample sizes, normative data, and comparable scales to help establish construct validity and cutoff scores.

    The purpose of this study is to determine battlefield effectiveness of the self-healing minefield (''Frogs'') concept system compared to basecases of the standard AP/AT (anti-personnel/anti-tank) mixed minefield, the AT (anti-tank) pure minefield, and no minefields. This involves tactical modeling where a basecase with and without mines is compared to the concept system. However, it is first necessary to establish system characteristics and behavior of the Frog mine and minefield in order to do the tactical modeling. This initial report provides emerging insights into various minefield parameters in order to allow better program definition early in the conceptual development. In the following sections of this report, we investigate the self-healing minefield's ground pattern and several concepts for movement (''jump'') of a mine. Basic enemy breaching techniques are compared for the different mine movement concepts. These results are then used in the (Joint Conflict and Tactical Simulation) JCATS tactical model to evaluate minefield effects in a combat situation. The three basecases and the Frogs concept are used against a North Korean mechanized rifle battalion and outcomes are compared. Preliminary results indicate: (1) Possible breaching techniques for the self-healing minefield were proposed and compared through simulation modeling. Of these, the best breaching counter to the self-healing minefield is the ''wide-lane'' breach technique. (2) Several methods for mine movement are tested and the optimal method from this group was selected for use in the modeling. However, continued work is needed on jump criteria; a more sophisticated model may reduce the advantage of the breach counter. (3) The battle scenario used in this study is a very difficult defense for Blue. In the three baseline cases (no mines, AT mines only, and mixed AT/AP minefield), Blue loses. Only in the Frog case does Blue win, and it is a high casualty win.

    This report presents a preliminary study investigating the effects of large-volume liposuction on the parameters that determine type 2 diabetes. The study enrolled 31 patients with a body mass index (BMI) exceeding 30 kg/m(2) over a 1-year period. All the liposuction procedures were performed with the patient under local anesthesia using ketamine/valium sedation. Pre- and postoperative blood pressure, fasting glucose, glycosylated hemoglobin (HbA1C), weight, and BMI were evaluated for 16 of the 30 patients who returned for a follow-up visit 3 to 12 months postoperatively. The average aspirate was 8,455 ml without dermolipectomy and 5,795 ml with dermolipectomy. The data reveal a trend of improvement in blood sugar levels associated with weight loss that helps the patients. The average blood sugar level dropped 18% in our return patients, and the average weight loss was 9.2%. The average drop in BMI was 6.2%, and HbA1C showed a decrease of 2.3%. The patients with the best weight loss had the best reduction in blood sugar level and blood pressure. No transfers to the hospital and no thromboebolism occurred for any of the 31 patients. One dehiscence, two wound infections, and three seromas were reported. The authors hypothesize that large-volume liposuction in their series may have motivated some to diet, which could be explored in a larger series with control groups. Liposuction alone did not improve obesity but helped to motivate some of the patients to lose weight. These patients had the best results.

    The EU-ADR project aims to exploit different European electronic healthcare records (EHR) databases for drug safety signal detection. In this paper we report the preliminary results concerning the comparison of signal detection between EU-ADR network and two spontaneous reporting databases, the Food and Drug Administration and World Health Organization databases. EU-ADR data sources consist of eight databases in four countries (Denmark, Italy, Netherlands, and United Kingdom) that are virtually linked through distributed data network. A custom-built software (Jerboa©) elaborates harmonized input data that are produced locally and generates aggregated data which are then stored in a central repository. Those data are subsequently analyzed through different statistics (i.e. Longitudinal Gamma Poisson Shrinker). As potential signals, all the drugs that are associated to six events of interest (bullous eruptions - BE, acute renal failure - ARF, acute myocardial infarction - AMI, anaphylactic shock - AS, rhabdomyolysis - RHABD, and upper gastrointestinal bleeding - UGIB) have been detected via different data mining techniques in the two systems. Subsequently a comparison concerning the number of drugs that could be investigated and the potential signals detected for each event in the spontaneous reporting systems (SRSs) and EU-ADR network was made. SRSs could explore, as potential signals, a larger number of drugs for the six events, in comparison to EU-ADR (range: 630-3,393 vs. 87-856), particularly for those events commonly thought to be potentially drug-induced (i.e. BE: 3,393 vs. 228). The highest proportion of signals detected in SRSs was found for BE, ARF and AS, while for ARF, and UGIB in EU-ADR. In conclusion, it seems that EU-ADR longitudinal database network may complement traditional spontaneous reporting system for signal detection, especially for those adverse events that are frequent in general population and are not commonly thought to be drug

    Parkinson's disease (PD) is a slowly progressing neurodegenerative disorder that affects approximately seven million patients worldwide. Despite intensive research, the molecular mechanisms initiating and promoting PD are still unknown. However, it is assumed that environmental factors trigger PD. Recent research demonstrated that long noncoding RNAs (lncRNA) interfere in transcriptional and translational processes modulating gene expression reflecting environmental influences. Nevertheless, there is no systematic analysis available that investigates the impact of lncRNAs on PD. In the current study, we performed a comprehensive analysis on expression levels of 90 well-annotated lncRNAs in 30 brain specimens deriving from 20 PD patients and 10 controls as a preliminary report on the significance of lncRNAs in PD. Expression profiling of lncRNAs revealed that five lncRNAs are significantly differentially expressed in PD. While H19 upstream conserved 1 and 2 is significantly downregulated in PD, lincRNA-p21, Malat1, SNHG1, and TncRNA are significantly upregulated. An analysis on expression levels and PD stages revealed that the identified dysregulated lncRNA are altered already in early disease stage and that they precede the course of PD. In summary, this is the first comprehensive analysis on lncRNAs in PD revealing significantly altered lncRNAs. Additionally, we found that lncRNA dysregulations precede the course of the disease. Thus, the five newly identified lncRNAs may serve as potential new biomarkers appropriate even in early PD. They may be used in monitoring disease progression and they may serve as potential new targets for novel therapeutic approaches.

    This report summarizes the acquisition, data processing, and preliminary interpretation of a high-resolution aeromagnetic and radiometric survey near the confluence of the Big and Little Chino basins in the headwaters of the Verde River, Arizona. The goal of the aeromagnetic study is to improve understanding of the geologic framework as it affects groundwater flow, particularly in relation to the occurrence of springs in the upper Verde River headwaters region. Radiometric data were also collected to map surficial rocks and soils, thus aiding geologic mapping of the basin fill. Additional gravity data were collected to enhance existing coverage. Both aeromagnetic and gravity data indicate a large gradient along the Big Chino fault, a fault with Quaternary movement. Filtered aeromagnetic data show other possible faults within the basin fill and areas where volcanic rocks are shallowly buried. Gravity lows associated with Big Chino and Williamson Valleys indicate potentially significant accumulations of low-density basin fill. The absence of a gravity low associated with Little Chino Valley indicates that high-density rocks are shallow. The radiometric maps show higher radioactivity associated with the Tertiary latites and with the sediments derived from them. The surficial materials on the eastern side of the Big Chino Valley are significantly lower in radioactivity and reflect the materials derived from the limestone and basalt east of the valley. The dividing line between the low radioactivity materials to the east and the higher radioactiviy materials to the west coincides approximately with the major drainage system of the valley, locally known as Big Chino Wash. This feature is remarkably straight and is approximately parallel to the Big Chino Fault. The uranium map shows large areas with concentrations greater than 5 ppm eU, and we expect that these areas will have a significantly higher risk potential for indoor radon.

    Genicular nerve ablation with radiofrequency (RF) has recently emerged as a promising treatment in the management of osteoarthritis related knee pain. To date, genicular nerve injections have been performed under fluoroscopic guidance. To evaluate the effect of ultrasound-guided genicular nerve pulsed RF treatment on chronic knee pain and function in patients with knee osteoarthritis. Single-arm prospective study. University hospital and rehabilitation center in Turkey. A review was made of 29 patients with medial knee osteoarthritis who had undergone genicular nerve block in the previous 6 months. Patients with at least 50% reduction in the visual analog scale (VAS) score after genicular nerve block and with no on-going pain relief were selected for the study. Ultrasound-guided genicular nerve pulsed RF was applied to 15 knees of 9 patients. Pain and knee function were assessed with 100-mm VAS and Western Ontario and McMaster Universities (WOMAC) index throughout 3 months. A significant reduction in VAS scores was detected over time after the pulsed RF procedure (f: 69.24, P < 0.01). There was a significant improvement in the WOMAC scores (f: 539.68 , P < 0.01). The small number of participants, the lack of a control group, and short follow-up period were limitations of the study. Genicular nerve pulsed RF treatment has been found to be safe and beneficial in osteoarthritis related knee pain. Further studies with a larger population and randomized controlled study design are warranted to confirm the positive findings of this preliminary report.

  12. Preliminary Report on U-Th-Pb Isotope Systematics of the Olivine-Phyric Shergottite Tissint

    Geochemical studies of shergottites suggest that their parental magmas reflect mixtures between at least two distinct geochemical source reservoirs, producing correlations between radiogenic isotope compositions, and trace element abundances.. These correlations have been interpreted as indicating the presence of a reduced, incompatible-element- depleted reservoir and an oxidized, incompatible-element-rich reservoir. The former is clearly a depleted mantle source, but there has been a long debate regarding the origin of the enriched reservoir. Two contrasting models have been proposed regarding the location and mixing process of the two geochemical source reservoirs: (1) assimilation of oxidized crust by mantle derived, reduced magmas, or (2) mixing of two distinct mantle reservoirs during melting. The former clearly requires the ancient martian crust to be the enriched source (crustal assimilation), whereas the latter requires a long-lived enriched mantle domain that probably originated from residual melts formed during solidification of a magma ocean (heterogeneous mantle model). This study conducts Pb isotope and U-Th-Pb concentration analyses of the olivine-phyric shergottite Tissint because U-Th-Pb isotope systematics have been intensively used as a powerful radiogenic tracer to characterize old crust/sediment components in mantle- derived, terrestrial oceanic island basalts. The U-Th-Pb analyses are applied to sequential acid leaching fractions obtained from Tissint whole-rock powder in order to search for Pb isotopic source components in Tissint magma. Here we report preliminary results of the U-Th-Pb analyses of acid leachates and a residue, and propose the possibility that Tissint would have experienced minor assimilation of old martian crust.

    By using quantitative image analysis of soft X-ray photographs on the bulk of extracted pineal glands and prostates, we made a preliminary investigation into the correlations among pineal concretions (% by mass), prostatic calculi (% by mass) and age (years) in 40 human adult males, ranging in age from 31 to 95 years (mean (+/-SD) 69.9 +/- 15.2 years), who died and underwent the routine dissection course. The mass concentrations of pineal concretions and prostatic calculi were 17.68 +/- 13.56% (range 0-51.34%) and 0.93 +/- 1.31% (range 0-5.82%), respectively. There was no correlation between the mass concentration of pineal concretions and aging (r = 0.03; P < 1.0). There was no correlation between mass concentration of prostatic calculi and aging (r = 0.28; P < 0.5). No pineal concretions and no prostatic calculi were observed in seven and 10 cases, respectively; in addition, in one case, neither-concretions nor calculi were seen. From such data and from the previously reported suggestion on the counteracting functions between the pineal gland and prostate, a negative correlation between the mass concentrations of pineal concretions and prostatic calculi was expected. This was certainly obtained, but the correlation was low (r = -0.39; P < 0.05). Such a low correlation and no correlations between the concentrations of pineal concretions and aging or between prostatic calculi and aging may have been caused by the examination of relatively older humans. Therefore, further investigations using a number of pair samples collected from males including younger age generations will be necessary.

    Cancer-related fatigue (CRF) is the most common and severe symptom in patients with cancer. The number and efficacy of available treatments for CRF are limited. The objective of this preliminary study was to assess the safety of high-dose Panax ginseng (PG) for CRF. In this prospective, open-label study, 30 patients with CRF (≥4/10) received high-dose PG at 800 mg orally daily for 29 days. Frequency and type of side effects were determined by the National Cancer Institute's Common Terminology Criteria for Adverse Events, version 4.0. Scores on the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) scale, Edmonton Symptom Assessment System (ESAS), and Hospital Anxiety and Depression Scale (HADS) were assessed at baseline, day 15, and day 29. Global Symptom Evaluation (GSE) was assessed at day 29. Of the 30 patients enrolled, 24 (80%) were evaluable. The median age was 58 years; 50% were females, and 84% were white. No severe (≥grade 3) adverse events related to the study drug were reported. Of the 24 evaluable patients, 21 (87%) had an improved (by ≥3 points) FACIT-F score by day 15. The mean ESAS score (standard deviation) for well-being improved from 4.67 (2.04) to 3.50 (2.34) (P = .01374), and mean score for appetite improved from 4.29 (2.79) to 2.96 (2.46) (P = .0097). GSE score of PG for fatigue was ≥3 in 15/24 patients (63%) with median improvement of 5. PG is safe and improves CRF fatigue as well as overall quality of life, appetite, and sleep at night. Randomized controlled trials of PG for CRF are justified. © The Author(s) 2015.

    Individuals with bipolar disorder (BD) are disproportionately affected by symptoms of being overweight and metabolic syndrome when compared to the general population. The pertinence of this observation is underscored by observations that excess weight is associated with a more complex illness presentation, course, and outcome in BD. We present the first preliminary report of our BIPFAT study, which explored shared hypothesized pathophysiological pathways between being overweight and having BD. We investigated the tryptophan-kynurenine metabolism pathway as a proxy of dysregulated inflammatory homeostasis in euthymic, overweight individuals with BD (n = 78) compared to healthy controls (n = 156). Both blood kynurenine concentrations and the kynurenine to tryptophan ratio [(Kyn:Trp); an estimate of tryptophan breakdown] were significantly higher in the total sample of euthymic patients with BD, with greater increases noted in both parameters in the subsample of overweight patients with BD. When compared to controls, peripheral neopterin concentrations were significantly lower. Within the BD group, there were also significant between-group differences in neopterin concentrations, with higher levels in those who were overweight and in subjects with BD in the later stages of illness compared to earlier stages. Increased tryptophan breakdown, as well as neopterin levels in BD, may be an indirect mediator of immune-mediated inflammation. In BD, this may account for the high prevalence of medical comorbidities and increased mortality. The observation of increased kynurenine levels and Kyn:Trp, and altered circulating neopterin levels provides indirect evidence of increased activity of tryptophan-degrading indoleamine 2,3-dioxygenase in euthymic individuals with BD, underscoring the role of inflammatory mediators as a causative and/or consequent factor. More robust abnormalities in the overweight subsample underscore the additional inflammatory burden of medical comorbidity

Contralesional omissions of single tactile stimuli, however, might be due to either primary somatosensory deficits or to spatial attention impairment (i.e., neglect). In this preliminary study, we tested whether clinical assessment can be improved to differentiate between these two types of deficit by modifying the assessment procedure. K.L., a patient with left unilateral neglect, was asked to detect tactile stimuli delivered in two conditions: spatial attention distributed either to his left or to his right hand, and spatial attention focused only on his left hand. Note that K.L. did not receive double simultaneous tactile stimuli. In the distributed spatial attention condition, K.L. omitted most of the single tactile stimuli delivered to his left hand. In the focused attention condition, K.L. was asked to focus his spatial attention only on his left hand. Under this latter condition, his performance increased dramatically, suggesting that his omissions were not due to hemianesthesia, but rather reflected left tactile neglect. In line with the neuropsychological findings, voxel based analysis of his grey and white matter damage confirmed significant loss in areas associated with left-sided neglect, but sparing of the primary somatosensory cortex. This result suggests that standard somatosensory assessment and differential diagnosis between hemianesthesia and tactile neglect may be more accurate when neuropsychology-based procedures are incorporated in the standard neurological examination.

  17. Preliminary report on the utilization of the Fermilab site for a future accelerator

    SciTech Connect

    Site Utilization Working Group

    1996-10-01

    This report is a preliminary assessment of the utility of the Fermilab site for future accelerator projects. It responds to a request from the Director to evaluate how the Fermilab site and infrastructure may be relevant to future accelerator projects in the U.S. The SSC experience suggests that any major new project will have to be based on the existing infrastructure at one of the National Laboratories. This work presents only the technical issues and the benefits of the Fermilab site and infrastructure. The projects treated are: (1) A really large hadron collider based on the ``Pipetron`` vision of low-field (2 Tesla) magnets in a small diameter tunnel. Another option, not treated in detail, is a hadron collider using high field magnets. (2) Muon Colliders with 250 GeV and 2 TeV per beam. (3) A linear electron collider with 250 to 500 GeV per beam. The infrastructure of the state of Illinois - geology, hydrology, power and surface water- seems remarkably well suited to any of these projects. The geology of most of Illinois, including Fermilab, contains a dolomite layer that: has low seismic activity, is at an appropriate depth to provide radiation protection, is essentially impervious to water movement and thus satisfies hydrology requirements. There is adequate electrical power - both locally and statewide. We first give brief overviews of the Fermilab and Illinois infrastructure - geology, hydrology, power, and water - and then a summary of each project. On the basis of what we have learned, we feel that Fermilab must be considered seriously as a site for any of these projects. Beyond this point, however site-specific plans will need to be developed for each of the projects.

    Cystic fibrosis is the most common fatal genetic disorder in the Caucasian population. Scoring systems for assessment of Cystic fibrosis disease severity have been used for almost 50 years, without being adapted to the milder phenotype of the disease in the 21st century. The aim of this current project is to develop a new scoring system using a database and employing various statistical tools. This study protocol reports the development of the statistical tools in order to create such a scoring system. The evaluation is based on the Cystic Fibrosis database from the cohort at the Royal Children's Hospital in Melbourne. Initially, unsupervised clustering of the all data records was performed using a range of clustering algorithms. In particular incremental clustering algorithms were used. The clusters obtained were characterised using rules from decision trees and the results examined by clinicians. In order to obtain a clearer definition of classes expert opinion of each individual's clinical severity was sought. After data preparation including expert-opinion of an individual's clinical severity on a 3 point-scale (mild, moderate and severe disease), two multivariate techniques were used throughout the analysis to establish a method that would have a better success in feature selection and model derivation: 'Canonical Analysis of Principal Coordinates' and 'Linear Discriminant Analysis'. A 3-step procedure was performed with (1) selection of features, (2) extracting 5 severity classes out of a 3 severity class as defined per expert-opinion and (3) establishment of calibration datasets. (1) Feature selection: CAP has a more effective "modelling" focus than DA.(2) Extraction of 5 severity classes: after variables were identified as important in discriminating contiguous CF severity groups on the 3-point scale as mild/moderate and moderate/severe, Discriminant Function (DF) was used to determine the new groups mild, intermediate moderate, moderate, intermediate

  1. Helical tomotherapy in the treatment of pediatric malignancies: a preliminary report of feasibility and acute toxicity

    PubMed Central

    2011-01-01

    Background Radiation therapy plays a central role in the management of many childhood malignancies and Helical Tomotherapy (HT) provides potential to decrease toxicity by limiting the radiation dose to normal structures. The aim of this article was to report preliminary results of our clinical experience with HT in pediatric malignancies. Methods In this study 66 consecutive patients younger than 14 years old, treated with HT at our center between January 2006 and April 2010, have been included. We performed statistical analyses to assess the relationship between acute toxicity, graded according to the RTOG criteria, and several clinical and treatment characteristics such as a dose and irradiation volume. Results The median age of patients was 5 years. The most common tumor sites were: central nervous system (57%), abdomen (17%) and thorax (6%). The most prevalent histological types were: medulloblastoma (16 patients), neuroblastoma (9 patients) and rhabdomyosarcoma (7 patients). A total of 52 patients were treated for primary disease and 14 patients were treated for recurrent tumors. The majority of the patients (72%) were previously treated with chemotherapy. The median prescribed dose was 51 Gy (range 10-70 Gy). In 81% of cases grade 1 or 2 acute toxicity was observed. There were 11 cases (16,6%) of grade 3 hematological toxicity, two cases of grade 3 skin toxicity and one case of grade 3 emesis. Nine patients (13,6%) had grade 4 hematological toxicity. There were no cases of grade 4 non-hematological toxicities. On the univariate analysis, total dose and craniospinal irradiation (24 cases) were significantly associated with severe toxicity (grade 3 or more), whereas age and chemotherapy were not. On the multivariate analysis, craniospinal irradiation was the only significant independent risk factor for grade 3-4 toxicity. Conclusion HT in pediatric population is feasible and safe treatment modality. It is characterized by an acceptable level of acute toxicity

    To determine if the rate of major discrepancies between resident preliminary reports and faculty final reports increases during the final hours of consecutive 12-hour overnight call shifts. Institutional review board exemption status was obtained for this study. All overnight radiology reports interpreted by residents on-call between January 2010 and June 2010 were reviewed by board-certified faculty and categorized as major discrepancies if they contained a change in interpretation with the potential to impact patient management or outcome. Initial determination of a major discrepancy was at the discretion of individual faculty radiologists based on this general definition. Studies categorized as major discrepancies were secondarily reviewed by the residency program director (M.H.S.) to ensure consistent application of the major discrepancy designation. Multiple variables associated with each report were collected and analyzed, including the time of preliminary interpretation, time into shift study was interpreted, volume of studies interpreted during each shift, day of the week, patient location (inpatient or emergency department), block of shift (2-hour blocks for 12-hour shifts), imaging modality, patient age and gender, resident identification, and faculty identification. Univariate risk factor analysis was performed to determine the optimal data format of each variable (ie, continuous versus categorical). A multivariate logistic regression model was then constructed to account for confounding between variables and identify independent risk factors for major discrepancies. We analyzed 8062 preliminary resident reports with 79 major discrepancies (1.0%). There was a statistically significant increase in major discrepancy rate during the final 2 hours of consecutive 12-hour call shifts. Multivariate analysis confirmed that interpretation during the last 2 hours of 12-hour call shifts (odds ratio (OR) 1.94, 95% confidence interval (CI) 1.18-3.21), cross

There is a brief description of the preliminary basket design and the features used to maintain a critically safe system. Following the basket description is a discussion of various criticality analyses used to evaluate burnup credit. The results from these analyses are then reviewed in the perspective of fuel burnups expected to be shipped to either the final repository or a Monitored Retrievable Storage (MRS) facility. The hurdles to employing burnup credit in the certification of any cask are then outlines and reviewed. the last section gives conclusions reached as to burnup credit for the BR-100 cask, based on our analyses and experience. All information in this study refers to the cask configured to transport PWR fuel. Boiling Water Reactor (BWR) fuel satisfies the criticality requirements so that burnup credit is not needed. All calculations generated in the preparation of this report were based upon the preliminary design which will be optimized during the final design. 8 refs., 19 figs., 16 tabs.

    2012-01-01

    The objective of this preliminary study was to examine the possible contribution of disordered control of motor unit (MU) recruitment and firing patterns in muscle weakness post-stroke. A novel surface EMG (sEMG) recording and decomposition system was used to record sEMG signals and extract single MU activities from the first dorsal interosseous muscle (FDI) of two hemiparetic stroke survivors. To characterize MU reorganization, an estimate of the motor unit action potential (MUAP) amplitude was derived using spike triggered averaging of the sEMG signal. The MUs suitable for further analysis were selected using a set of statistical tests that assessed the variability of the morphological characteristics of the MUAPs. Our preliminary results suggest a disrupted orderly recruitment based on MUAP size, a compressed recruitment range, and reduced firing rates evident in the paretic muscle compared with the contralateral muscle of one subject with moderate impairment. In contrast, the MU organization was largely similar bilaterally for the subject with minor impairment. The preliminary results suggest that MU organizational changes with respect to recruitment and rate modulation can contribute to muscle weakness post-stroke. The contrasting results of the two subjects indicate that the degree of MU reorganization may be associated with the degree of the functional impairment, which reveals the differential diagnostic capability of the sEMG decomposition system.

    Regional comparisons (cortical surface area and thickness) were performed on a well described sample of adults with reading disability alone (RD), nonverbal giftedness alone (G), and reading disability and nonverbal giftedness combined (GRD). These anatomical results are considered in relation to behavioral and functional work previously reported on this sample. GRD-RD regional differences were found in both hemispheres and were more common than GRD-G differences. Regional differences were found in the temporal, parietal, occipital and frontal lobes. While these data are preliminary given the small sample sizes, they suggest future avenues of research on the neurodevelopment of atypical samples.

  9. Congenital pseudoarthrosis of the tibia: healing by lengthening over a rod without compression of the nonunion. A preliminary report.

    2013-05-01

    This preliminary report is on two patients with congenital pseudoarthrosis of the tibia who had a persistent nonunion following intramedullary rodding and bone grafting. We do not advocate repeated surgery to achieve union. When limb length discrepancy becomes greater than 5 cm, we proceeded with an Ilizarov procedure with the primary aim of equalizing limb length rather than achieving union. Healing of the pseudoarthrosis occurred in both patients after lengthening over the intramedullary rod without compression of the nonunion site. We believe that union occurs because of hyperaemia during the lengthening. This approach minimizes the repeated surgeries that are usually needed and thus ensures a more normal childhood without frequent hospitalizations.

    2014-01-01

    The Medical Device regulation requires manufacturers to anticipate and prevent risks of use errors of their medical device. However, manufacturers experience difficulties to understand the concept of "usability-induced use-errors". Based on a "usability framework" aiming at describing the relationship between usability design principles, usability flaws, usage problems, and outcomes, a usability evaluation reporting form had been designed to support understanding the use-error concept. This paper reports the preliminary evaluation of the perceived usefulness of this form. Results show that manufacturers found helpful the presentation of the results of a usability evaluation through this form for it supports the understanding of the usability origins and the consequences of use-errors. Even if the use of this reporting form should be made easier as usability experts experience difficulties to fill it, it seems a promising way to clearly present "usability-induced use-errors" to manufacturers.

    Background Chronic stress and related physiological responses are known to have deleterious effects on neural integrity. Combat exposure is a notoriously pathogenic stressor and with over 2 million U.S. troops deployed to active combat zones since 2001, there is an urgent need to advance our understanding of its potential neural impact. Previous evidence suggests structural alterations in PTSD and more recent studies have explored cortical thinning specifically. This preliminary study investigates the impact of combat exposure on cortical thickness, controlling for history of early life stress and age. Methods Twenty-one combat-exposed Veterans with PTSD and 20 non-PTSD combat-exposed controls (mean age 32.7) completed the Combat Exposure Scale, Childhood Trauma Questionnaire and structural magnetic resonance imaging in a Siemens 3T TIM trio system. GLM was used to examine the effect of combat exposure on cortical thickness, controlling for early life trauma exposure and age using cluster-wise correction (p<0.05). Results This preliminary study found a negative correlation between combat exposure severity (CES) and cortical thickness in the left superior temporal and left rostral middle frontal regions, as well as an interaction between PTSD diagnosis status and CES, in the superior temporal/insular region showing a stronger negative correlation between CES and cortical thickness in the non-PTSD group. Conclusions Though caution should be taken with interpretation given the preliminary nature of the findings, the results indicate combat exposure may affect cortical structure beyond possible alterations due to early life stress exposure or PTSD psychopathology. Though replication in larger samples is required, these results provide useful information regarding possible neural biomarkers and treatment targets for combat-related psychopathology as well as highlighting the pathogenic effects of combat.

    A flight propulsion system preliminary design was established that meets the program goals of at least a 12 percent reduction in thrust specific fuel consumption, at least a five percent reduction in direct operating cost, and one-half the performance deterioration rate of the most efficient current commercial engines. The engine provides a high probability of meeting the 1978 noise rule goal. Smoke and gaseous emissions defined by the EPA proposed standards for engines newly certified after 1 January 1981 are met with the exception of NOx, despite incorporation of all known NOx reduction technology.

    A conventional static ultrasound B scanner with a 6 mm diameter 5 MHz transducer was used to examine the brains of 12 infants between one week and eight months of age using the anterior fontanelle as an ultrasound window. High resolution pictures were obtained allowing assessment of cortical thickness, ventricular size and intracranial haemorrhage. Comparisons of these pictures with those obtained in the same patients by computerized tomography showed excellent correlation. Ultrasound is a simple, non-invasive diagnostic technique. In this small preliminary series its performance has altered the diagnosis and influenced the management in several cases.

    The transient event counter is described, defining its operational characteristics, and presenting the preliminary results obtained through the first 90 days of operation including the Spring 1976 eclipse season. The results show that the CTS was charged to the point where discharges have occurred. The discharge induced transients have not caused any anomalous events in spacecraft operation. The data indicate that discharges can occur at any time during the day without preference to any local time quadrant. The number of discharges occurring in the 1 sec sample interval are greater than anticipated.

    Preliminary findings are presented regarding Visi-Pitch settings in relation to automatically derived perturbation values (jitter). Jitter values were estimated from sustained phonation of /a/ at each of four filter settings for three subjects using Visi-Pitch. Data were compared to values obtained by hand measuring the same signals and employing Koike's formula. Results indicated that the magnitude of difference between jitter estimated by Visi-Pitch and hand measurement was small. Findings support the use of the manufacturer's recommended filter settings as opposed to alternative settings suggested by Karnell.

    Nearly half of Americans who die in hospitals spend time in the intensive care unit (ICU) in the last 3 days of life. Minority patients who die in the ICU are less likely to formalize advance directives and surviving family members report lower satisfaction with the provision of information and sensitivity to their cultural traditions at the end-of-life. This is a descriptive report of a convenience sample of 157 consecutive patients served by a palliative care team which was integrated into the operations of an ICU at Montefiore Medical Center in the Bronx, New York, from August 2005 until August 2007. The team included an advance practice nurse (APN) and social worker. A separate case-control study was conducted comparing the length of hospital stay for persons who died in the ICU during the final 6 months of the project, prior to and post-palliative care consultation for 22 patients at the hospital campus where the project team was located versus 24 patients at the other campus. Pharmaco-economic data were evaluated for 22 persons who died with and 43 who died without a palliative care consultation at the intervention campus ICU to evaluate whether the project intervention was associated with an increase in the use of pain medications or alterations in the use of potentially non-beneficial life-prolonging treatments in persons dying in the ICU. Data was abstracted from the medical record with a standardized chart abstraction instrument by an unblinded research assistant. Interviews were conducted with a sample of family members and ICU nurses rating the quality of end-of-life care in the ICU with the Quality of Dying and Death in the ICU instrument (ICUQODD), and a family focus group was also conducted. Forty percent of patients were Caucasian, 35% were African American or Afro-Caribbean, 22% Hispanic and 3% were Asian or other. Exploration of the patients' and families' needs identified significant spiritual needs in 62.4% of cases. Education on the death

    This report presents the results of the preliminary assessment (PA) conducted by Argonne National Laboratory at the Georgia Army National Guard property located on Hunter Army Airfield (HAA) near Savannah, Georgia, known as Army Aviation Support Facility (AASF) No. 3. Preliminary assessments of federal facilities are being conducted to compile the information necessary for completing preremedial activities and to provide a basis for establishing corrective actions in response to releases of hazardous substances. The principal objective of the PA is to characterize the site accurately and determine the need for further action by examining site activities, types and quantities of hazardous substances utilized, the nature and amounts of wastes generated or stored at the facility, and potential pathways by which contamination could affect public health and the environment. This PA satisfies, for the AASF No. 3 property, requirements of the Department of Defense Installation Restoration Program (IRP). The scope of this assessment is limited to the facilities and past activities contained within the area now occupied by AASF No. 3. However, this assessment report is intended to be read in conjunction with a previous IRP assessment of HAA completed in 1992 (USATHAMA 1992) and to provide comprehensive information on AASF No. 3 for incorporation with information contained in that previous assessment for the entirety of HAA.

    We analyzed the efficiency of a new plate DiPhos-RM in CFR-PEEK [carbon-fiber-reinforced poly (etheretherketone)] for the volar fixation of distal radius fractures. The new plate's composition has the advantage of x-ray absolute transparency, therefore allowing to monitor the healing of the fracture. The desired combination of high strength and low rigidity is obtained through the use of the polymer composites CFR-PEEK. In this preliminary study (from March 2012 to June 2012), 10 cases of intra-articular distal radius fractures were treated with DiPhos-RM produced by Lima Corporate (Italy). The fractures were classified according to the AO classification, 4 fractures were type C1, 3 type C2, and 3 were A2. A preoperative computed tomography scan was carried out in all patients. One patient also underwent a postoperative computed tomography scan. Grip strength, range of motion, and DASH score were evaluated at follow-up. There were no cases of hardware failure. Specifically, no loss of position or alignment of fixed-angle locking screws or breakage of the plate were observed. Radiographic union was present at an average of 6 weeks (range, 5 to 8 wk). The overall preliminary experience with this new plate is favorable. The new plate is easy to apply and provides the surgeon dual options of fixed-angle or variable-angle screws. It was rigid enough to maintain the reduction also in AO type C articular fractures.

    SUMMARY Aim. In this preliminary study, the 3-year radiological outcomes of Osseospeed implant-supported fixed complete or partial prostheses made with two different laboratory protocols were compared. Methods. A convenience sample of 34 patients, who were either partially or completely edentulous in either jaw, were randomly assigned to two groups, of 17 patients each, using either a traditional laboratory protocol (control group) or the Cresco one (test group). The study’s objective was an assessment of marginal bone loss around implants, measured on intraoral radiographs at 3-year follow-up. Results. None of the implants inserted was lost during the study and radiological measurements of marginal bone level changes revealed that the mean marginal bone loss was respectively 0,73±0,33mm for test group and 0,88±1,13mm for control group. The differences between test and control groups were not statistically significant. Conclusion. This preliminary study did not demonstrate statistically significant differences in marginal bone loss around implant-prostheses prepared with the two different laboratory protocols, over the 3-year observational period.

    The increased use of explosives in combat has resulted in a large number of returning veterans suffering from blast-related mild traumatic brain injury (mTBI) and self-reported complications. It remains unclear whether this increase in self-reported difficulties is unique to the blast mechanism or stressful preinjury environment and whether cognitive-functioning deficits correspond with these difficulties in the postacute phase. This study examined the relationship between cognitive performance and self-reported psychological and somatic symptoms of blast-related mTBI compared with civilian mTBI, independent of comorbid posttraumatic stress disorder (PTSD) symptoms. Twelve veterans with blast-related mTBI were compared to 18 individuals with civilian mTBI on cognitive tests and self-report questionnaires. Univariate analyses failed to reveal differences on any individual cognitive test. Further, veterans reported more psychological and somatic complaints. These self-reported difficulties were not significantly correlated with neuropsychological performance. Overall, preliminary results suggest that in the postacute phase, subjective complaints related to blast-related mTBI do not covary with objective cognitive performance. Additionally, cognitive outcomes from blast-related mTBI were similar to those of civilian forms of mTBI. Future studies should identify the cognitive and self-reported sequelae of blast-related mTBI independent of comorbid PTSD in a larger sample of veterans.

    The Geological Survey's "Contributions to economic geology" are published in two parts, one including papers on metals and nonmetals except fuels and the other including papers on mineral fuels. As the subtitle indicates, most of the papers in these volumes are of three classes (1) short papers describing as thoroughly as conditions will permit areas or deposits on which no other report is likely to be prepared; (2) brief notes on mining districts or economic deposits whose examination has been merely incidental to other work; and (3) preliminary reports on economic investigations the results of which are to be published later in more detailed form. Although these papers set forth mainly the practical results of economic investigations, they include brief theoretical discussions and summary statements of conclusions if these appear to require prompt publication.

    This report contains the preliminary design of an SCEAS Engineering Test Facility (ETF). The ETF is a 3600 m/sup 2/ fluid roof greenhouse with an inflated plastic film roof to maintain a clean environment for the fluid roof and to protect the inner glazing from hail and other small missiles. The objective of the design was the faithful scaling of the commercial facility to ensure that the ETF results could be extrapolated to a commercial facility of any size. Therefore, all major features, including the photovoltaic power system, an integral water desalination system and even the basic structural module have been retained. The design is described in substantial detail in the body of this report, with appendices giving the drawings and specifications.

    The reliability and validity of self-reported assessment of exposure and outcome variables were examined for manual lifting activities among ten physiotherapists. In this study, the participants evaluated the effects of five lifting variables on perceived effort, twice separated by a one-week period. One hundred and sixty-two lifting conditions were evaluated by each subject. The exposure and outcome lifting variables were described in linguistic terms. Intra-class correlation coefficient (ICC(1,1)) analysis revealed a mean value of 0.62 for all lifting activities. The self-reported assessment was cross-validated with the NIOSH lifting index by mapping the linguistic variables into numerical ranges. Moderate correlations (r = 0.54 and 0.53, p<0.01) were obtained between perceived physical exertion/perceived risk and lifting index. The findings of this study provide preliminary indications that human-based methodologies may be further explored on experienced workers.

    The preliminary design and cost estimate of a compressed air energy storage (CAES) plant located in the Middle South Utilities (MSU) system are summarized in this report. The 220 MWe CAES plant which stores air in two solution mined salt caverns, is located at the Carmichael salt dome near Jackson, Mississippi. The facility criteria, site selection and the turbomachinery and auxiliaries, are briefly described together with an outline of the proposed procedure for developing the caverns. Using this information and data, the preliminary CAES plant design was prepared; also the capital cost estimate, cash flow and project schedule were developed. The Environmental Assessment did not reveal any major site impediments to the construction of the plant. However, it is believed that an EIS is required primarily because CAES is a new technology without precedent in the United States. Although a final system planning study was not completed because of lack of funds, from preliminary analysis a CAES plant does not appear to be economic in the MSU system before the mid 1990s. This is due to the unique features of the MSU system. For other systems under more favorable conditions, CAES may be economic at an earlier date. The construction of a CAES plant with salt cavern air storage may by considered ready for use as a commercial electric generating plant. The experience at the Huntorf plant in West Germany demonstrates the technical feasibility of the CAES concept. Certain details of the plant defined in this study are different from the Huntorf plant. Design verification by limited testing and analysis would provide added confidence to those considering a CAES plant.

    Previous studies with cultured human normal fibroblasts indicated that treatment of cells with zinc before exposure to alkylating agents enhanced cell survival by seven- to nine-fold. To establish whether a similar zinc-induced protective response could be elicited in vivo, a set of preliminary experiments was carried out in which Balb/cJ mice were treated with zinc chloride (2 mg/kg body weight) or saline by intraperitoneal (ip) injection at 48, 36, 24, and 12 h before ip administration of 4 mg/kg of the alkylating agent nitrogen mustard. Of the animals that received saline before nitrogen mustard, 57% were killed compared with only 20% in the group treated with zinc before administration of the alkylating agent. These results (which almost certainly were achieved with less than optimal induction conditions) provide evidence for the existence, in vivo, of a zinc-inducible process that reduces alkylating agent lethality. 12 refs., 4 figs.

    Ethanolic extracts of Ailanthus exceisa (AE). Toddalia asiatica (TA) and Araucaria bidwilli (AB) were screened by the anti-pyretic activity in yeast induced hyperthermic test model in the laboratory. Dose of AE (100), TA (60) and AB (30) mg., equivalent of the plant material per kg. Body weight of the extracts were administered orally to the female albino rats. Acute toxicity and preliminary phytochemical screening were conducted for all the extracts. LD 50 values on oral administration of the extracts were found to be AE (1000), AB (350) and TA (250) mg. per kg. body weight respectively. Both the root and aerial part fractions of TA displayed a pronounced anti-pyretic activity comparable to the standard drug paracetamol. AB oleoresin fraction was also found to show anti-pyretic effect. These observations however, confirm the folk-medical practices still prevailing among the tribes. PMID:22556707

    The purpose of this preliminary investigation was to assess the influence of palatal morphology on deformation of maxillary complete dentures in vivo. The palatal morphology of the maxillae of eight edentulous subjects was measured. Experimental dentures were fabricated, and a strain gauge was attached at the first molar position at the midline of the polished surface of each denture. Subjects were instructed to bite a metal bar placed bilaterally at the denture's first molar region with a force of 49 N. The resultant strains were recorded, and the correlation between strain and palatal morphology was evaluated using the Pearson correlation coefficient. A strong correlation between strain and both palatal depth and radius of curvature was noted, suggesting that edentulous patients with wide, shallow palates have a higher risk of denture deformation, which may lead to material fracture.

    The Central Landfill Site (CLS) is on the National Priorities List. CLS is owned by the Rhode Island Solid Waste Management Corporation and supported by state funds. Preliminary on-site sediment sampling results have identified cadmium, barium, lead, perchloroethylene, and chlorobenzene. Arsenic, lead, and mercury were identified in subsurface soil. In addition, 2,4-D, and 2,4,5-T were identified in on-site groundwater. The site is considered to be of imminent public health concern because of the risk to human health caused by the likelihood of human exposure to hazardous substances. Direct contact and ingestion of contaminated groundwater and soil are the human exposure pathways of concern.

    Assay of estrogen receptor activity in prostates from patients who ranged in age from 22 to 78 years and had not received any previous hormonal therapy was carried out by incubation of cytosols with (3)H-estradiol in the presence and absence of excess, nonradioactive estradiol. Hyperplastic prostatic tissues were used in the study. The kinetics of each reaction were studied and analysis of the data revealed 3.4 to 35.7 femtomoles of receptor protein per mg of cytosol protein; the dissociation constants obtained from a Scatchard plot ranged from 1.1 × 10(-10) to 1.2 × 10(-8)M.The small number of patients prevents realistic quantitative assessment of the apparent estrogen binding activity demonstrated in these preliminary studies, but the qualitative identification of such activity provides possible grounds for further insight into the hormonal mechanisms in the pathophysiology of prostatic diseases and of their responses to endocrine therapy.

    Field mapping has produced a preliminary picture of Mohon Mountain as a composite volcano, in which pyroclastic ash and larger tephra erupted alternately with flows of rhyodacite and dacite. An analog study which uses imagery of lunar and Martian features will compare the overall shape of the vent complex, including its breached southern flank and satellite vents, to similar landforms found on Mars and the Moon which are believed to have formed similar processes. Ash flow sheets were hypothesized to comprise the outer slopes of Olympus Mons suggesting that explosive eruptions which are more volatile-rich than those which produce basalt flows are not confined to terrestrial settings but may also be found on bodies such as Mars, which have a thicker crust and deeper magma source in the mantle. The analog study will explore further evidence for explosive eruptions on Mars and the Moon.

    The Spacecraft Control Laboratory Experiment (SCOLE) was conceived to provide a physical test bed for investigation of control techniques for large flexible spacecraft. The SCOLE problem is defined as two design challenges. The first challenge is to design control laws for a mathematical model of a large antenna attached to the space shuttle by a long flexible mast. The second challenge is to design and implement a control scheme on a laboratory representation of the structure modelled in the first part. Control sensors and actuators are typical of those which the control designer would have to deal with on an actual spacecraft. The primary control processing computer is representative of the capacity and speed which may be expected in actual flight computers. A brief description is given of the laboratory apparatus along with some preliminary results of structural dynamics tests and actuator effectiveness tests.

    A preliminary assessment of Steam Generator (SG) modelling in the PWR thermal-hydraulic code RELAP5/MOD3 is presented. The study is based on calculations against a series of steady-state commissioning tests carried out on the Wolf Creek PWR over a range of load conditions. Data from the tests are used to assess the modelling of primary to secondary side heat transfer and, in particular, to examine the effect of reverting to the standard form of the Chen heat transfer correlation in place of the modified form applied in RELAP5/MOD2. Comparisons between the two versions of the code are also used to show how the new interphase drag model in RELAP5/MOD3 affects the calculation of SG liquid inventory and the void fraction profile in the riser.

    Preliminary data are presented on the variation of the maximum lift coefficient with Mach number. The data were obtained from tests in the 8-foot high-speed tunnel of three NACA 16-series airfoils of 1-foot chord. Measurements consisted primarily of pressure-distribution measurements in order to illustrate the nature of the phenomena. It was found that the maximum lift coefficient of airfoils is markedly affected by compressibility even at Mach numbers as low as 0.2. At high Mach numbers pronounced decrease of the maximum lift coefficient was found. The magnitude of the effects of compressibility on the maximum lift coefficient and the low speeds at which these effects first appear indicate clearly that consideration of the take-off thrust for propellers will give results seriously in error if these considerations are based on the usual low-speed maximum-lift-coefficient data generally used.

    We observed six cases of patients in a dialysis programme who were apparently intoxicated by ingestion of star fruit. After ingestion of 2-3 fruits or 150-200 ml of the fruit juice, the six patients, who had previously been stable in a regular dialysis programme, developed a variety of symptoms ranging from insomnia and hiccups to agitation, mental confusion and (in one case) death. In preliminary investigations to characterize the hypothetical neurotoxin in the fruit, an extract, when injected intraperitoneally or intracerebroventricularly in rats, provoked persistent convulsions of the tonic-clonic type. It appears that star fruit (Averrhoa carambola) contains an excitatory neurotoxin. Patients with renal failure on conservative or dialysis treatment should be dissuaded from ingestion of the fruit.

    The rapid technical development of cardiac MR imaging in the last decade enables us today to evaluate cardiac morphology, function and viability in a reliable and very good spatial and temporal resolution. The advanced technology allows us to conduct those examinations in an acceptable time for clinical daily use and thus, the number of indications for cardiac MR imaging is steadily increasing. Since the beginning of 2004, a dedicated cardiac MR scanner has been employed in the Department of Medical Imaging in the Sheba Medical Center. We hereby conclude our preliminary experience with 58 sequential cases that were referred for cardiac MR imaging. Indications for the examination included 17 patients with congenital cardiac and great vessels anomalies, 14 patients with a suspected cardiac mass, 12 patients with suspected right ventricular dysplasia, and 4 patients with suspected constrictive pericarditis. This article also includes a review of the main indications for obtaining cardiac MR imaging.

    A preliminary serological study of 366 household dogs in Lagos and Ibadan, southwestern Nigeria, was carried out to determine antibodies due to exposure to Brucella abortus and B. canis, using the rose bengal test (RBT) and the rapid slide agglutination (RSA) test, respectively. Results showed that 5.46 % (20/366) and 0.27 % (1/366) of the dogs screened were seropositive to B. abortus and B. canis, respectively. Of all dogs, 36 had a history of being fed foetuses from cows and 11 (30.6 %) of these tested positive in the RBT. Our findings, although based on a limited sample size and a dearth of clinical details, revealed that dogs in Nigeria may be infected with Brucella spp. given the wide range of risk factors. Further studies are recommended to elucidate the epidemiology of brucellosis in dogs and its possible zoonotic consequences in the country.

    There is no widely accepted treatment for non-alcoholic fatty liver disease (NAFLD) or its advanced form, non-alcoholic steatohepatitis (NASH). We administered rosuvastatin (10 mg/day) for 1 year in patients with metabolic syndrome (MetS), NASH on liver biopsy and dyslipidaemia (but without diabetes or arterial hypertension). Patients also received lifestyle advice. We report preliminary results for 6 patients. The second biopsy (at the end of the study) showed complete resolution of NASH in 5 patients, while the 6(th), which had no improvement, developed arterial hypertension and substantial rise in triglyceride levels during the study. We suspect alcohol abuse despite advice to abstain. Serum alanine transaminase (ALT) and aspartate transaminase (AST) activities were reduced by 76 and 61%, respectively (p < 0.001 for both), during treatment, while γ-glutamyl transpeptidase (γ-GT), and alkaline phosphatase (AP) showed smaller non significant reductions. Fasting plasma glucose and glycated haemoglobin (HbA1c) were significantly reduced (p<0.05). Lipid values were totally normalised and liver ultrasonography showed a complete resolution of NASH in 5 patients. Body mass index and waist circumference remained unchanged during the study. Thus, changes in liver pathology and function should be attributed to treatment with rosuvastatin. A substantial limitation of the study is the small number of patients. These preliminary findings suggest that rosuvastatin could ameliorate NASH within a year of treatment in MetS patients with dyslipidaemia.

    Late diagnosis and interventions characterize childhood neurodevelopmental disorders in Sub-Saharan Africa. This has negatively impacted on the prognosis of the children with neurodevelopmental disorders. This study examined the prevalence and pattern of neurodevelopmental delays among children under the age of 3 years attending immunization clinics in Lagos State, Nigeria and also affords opportunity of early follow-up and interventions, which had been documented to improve prognosis. The study involved two stage assessments; which consisted of first phase screening of the children for neurodevelopmental delays in immunization clinics at primary healthcare centers Lagos State, Nigeria and second phase which consists of definitive clinical evaluation and follow-up interventions for children screened positive for neurodevelopmental delays. Twenty seven (0.9%) of a total of 3,011 children under the age of 3 years were screened positive for neurodevelopmental delays and subsequently undergoing clinical evaluation and follow-up interventions. Preliminary working diagnoses among these children include cerebral palsy, autism spectrum disorder trait, nutritional deficiency, Down syndrome and Non-specific neurodevelopmental delay with co-morbid seizure disorder accounting for 33.3%, 14.8%, 18.5%, 7.4% and 25.9% respectively. This is a preliminary report that would be followed up with information on medium and long term intervention phase.

    This report presents the results of the preliminary assessment (PA) conducted by Argonne National Laboratory at the Massachusetts Army National Guard (MAARNG) property known as the Army Aviation Support Facility 2 (AASF 2) near Chicopee, Massachusetts. Preliminary assessments of federal facilities are being conducted to compile the information necessary for completing preremedial activities and to provide a basis for establishing corrective actions in response to releases of hazardous substances. The principal objective of the PA is to characterize the site accurately and determine the need for further action by examining site activities, quantities of hazardous substances present, and potential pathways by which contamination could affect public health and the environment. The AASF 2 is a 10-acre site located in the western portion of Massachusetts, in the town of Chicopee, in the county of Hampden. The facilities included in this PA are Building 7400, adjacent paved areas, grassy areas, and the hazardous waste drum storage buildings. The environmentally significant operations (ESOS) associated with the property are (1) the waste drum storage area, (2) abandoned underground storage tanks (USTs), and (3) refueling activities.

    This preliminary study examined the relationship between anxiety disorders and self-reported history of teasing or bullying experiences, comparing individuals with social phobia, obsessive compulsive disorder, and panic disorder with or without agoraphobia. Given that aversive conditioning experiences, such as severe teasing, have been proposed to play a role in the development of social phobia and that the core feature of social phobia is a fear of social situations in which a person may be embarrassed or humiliated, we hypothesized that the social phobia group would have a higher rate of self-reported teasing history than would the obsessive compulsive disorder or panic disorder groups. Consistent with this hypothesis, a relationship between reported history of teasing and diagnosis was found. A significantly greater percentage of participants in the social phobia group (92%) reported a history of severe teasing experiences compared with the obsessive compulsive disorder (50%) and panic disorder (35%) groups. History of teasing experiences was also significantly related to an earlier age of onset for all 3 anxiety disorders, and to a greater number of self-reported additional problems in childhood. These findings suggest further directions for research in this area and highlight the significant link between perceptions of teasing in childhood and social phobia.

These tests, sponsored by Amtrak and supported by the FRA, were conducted to assess the suitability of the X2000 trainset for safe operation at elevated cant deficiencies and speeds in Amtrak's Northeast Corridor under existing track conditions in a revenue service demonstration. The report describes the safety criteria against which the performance of the X2000 test train was examined, the instrumentation used, the test locations, and the track conditions. Preliminary results are presented from tests conducted on Amtrak lines between Philadelphia and Harrisburg, PA, and between Washington DC and New York NY, in which cant deficiencies of 12.5 inches and speeds of 154 mph were reached in a safe and controlled manner. The significance of the results is discussed, and preliminary conclusions and recommendations are presented.

    The present study examined associations between childhood attention-deficit-hyperactivity disorder (ADHD) symptoms and adulthood dissociation in 799 male inmates using self-reporting questionnaires. Consequently, 33% of the subjects reported childhood physical abuse, and 11.8% reported childhood sexual abuse. A significant association was found between childhood ADHD symptoms and current dissociative tendency (r = 0.51, P < 0.001). Clinical implications of intervention focusing on dissociation in correctional/forensic practices for adult offenders are discussed.

    Purpose: To characterize kidney function in children and adolescents who had undergone radiation treatment that included parts of the kidney. Methods and Materials: Patients receiving radiotherapy during childhood or adolescence were prospectively registered in Germany's Registry for the Evaluation of Side Effects after Radiation in Childhood and Adolescence (RiSK). Detailed information was recorded regarding radiation doses at the organs at risk since 2001 all over Germany. Toxicity evaluation was performed according to standardized Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer criteria. Results: Up to May 2009, 1086 patients from 62 centers were recruited, including 126 patients (median age, 10.2 years) who underwent radiotherapy to parts of the kidneys. Maximal late toxicity (median follow-up 28.5 months in 74 patients) was characterized as Grade 0 (n = 65), 1 (n = 7) or 2 (n = 2). All patients with late effects had received potentially nephrotoxic chemotherapy. A statistically significant difference between patients with and without Grade 1 toxicity, revealing higher exposed kidney volumes in patients with toxicity, was seen for the kidney volume exposed to 20 Gy (V20; p = 0.031) and 30 Gy (V30; p = 0.003). Conclusions: Preliminary data indicate that radiation-induced kidney function impairment is rare in current pediatric multimodal treatment approaches. In the future, RiSK will be able to provide further detailed data regarding dose-volume effect relationships of radiation-associated side effects in pediatric oncology patients.

    OBJECTIVE--To devise and evaluate a rapid screening method for detecting trisomy 21 (Down's syndrome) in samples of uncultured amniotic fluid cells. DESIGN--Non-radioactive in situ hybridisation with HY128, a 500,000 base pair yeast artificial chromosome probe specific for chromosome 21. Blinded study of 12 karyotypically normal amniotic fluid samples and eight samples trisomic for chromosome 21. SETTING--Cytogenetic and obstetric services at a tertiary referral centre, Copenhagen. MAIN OUTCOME MEASURES--Time necessary to complete the test. Proportion of cell nuclei containing two and three hybridisation signals in karyotypically normal and abnormal amniotic fluid samples. RESULTS--The test could be completed within three to four days after amniocentesis. In the normal samples a mean of 73% (range 61-82%) of the amniotic cell nuclei showed two hybridisation signals and 6% (0-18%) showed three signals. By contrast, among the trisomic samples 29% (19-38%) of the nuclei exhibited two signals and 48% (31-60%) showed three signals. CONCLUSION--The technique clearly distinguished between normal and trisomic samples. Prenatal diagnosis with in situ hybridisation with chromosome specific probes was fast and may make it possible to screen for selected, aneuploidies. However, the technique is still at a preliminary stage and needs further evaluation and refinement. Images p1537-a PMID:1385745

    A preferred design and configuration approach for the DAWT innovative wind energy conversion system is suggested. A preliminary economic assessment is made for limited production rates of units between 5 and 150 kW rated output. Nine point designs are used to arrive at the conclusions regarding best construction material for the diffuser and busbar cost of electricity (COE). It is estimated that for farm and REA cooperative end users, the COE can range between 2 and 3.5 cents/kWh for sites with annual average wind speeds of 16 and 12 mph (25.7 and 19.3 km/h) respectively, and 150 kW rated units. No tax credits are included in these COE figures. For commercial end users of these 150 kW units, the COE ranges between 4.0 and 6.5 cents/kWh for 16 and 12 mph sites. These estimates in 1971 dollars are lower than DOE goals set in 1978 for the rating size and end applications. Recommendations are made for future activities to maintain steady, systematic progress toward mature development of the DAWT.

    Wind-tunnel tests were conducted on a model wing-nacelle combination to determine the practicability of cooling radial engines by forcing the cooling air into wing-duct entrances located in the propeller slipstream, passing the air through the engine baffles from rear to front, and ejecting the air through an annular slot near the front of the nacelle. The tests, which were of a preliminary nature, were made on a 5-foot-chord wing and a 20-inch-diameter nacelle. A 3-blade, 4-foot-diameter propeller was used. The tests indicated that this method of cooling and cowling radial engines is entirely practicable providing the wing of the prospective airplane is sufficiently thick to accommodate efficient entrance ducts , The drag of the cowlings tested was definitely less than for the conventional N.A.C.A. cowling, and the pressure available at low air speed corresponding to operation on the ground and at low flying speeds was apparently sufficient for cooling most present-day radial engines.

  16. Gene Expression Profiling in Hereditary, BRCA1-linked Breast Cancer: Preliminary Report

    2006-01-01

    Global analysis of gene expression by DNA microarrays is nowadays a widely used tool, especially relevant for cancer research. It helps the understanding of complex biology of cancer tissue, allows identification of novel molecular markers, reveals previously unknown molecular subtypes of cancer that differ by clinical features like drug susceptibility or general prognosis. Our aim was to compare gene expression profiles in breast cancer that develop against a background of inherited predisposing mutations versus sporadic breast cancer. In this preliminary study we analysed seven hereditary, BRCA1 mutation-linked breast cancer tissues and seven sporadic cases that were carefully matched by histopathology and ER status. Additionally, we analysed 6 samples of normal breast tissue. We found that while the difference in gene expression profiles between tumour tissue and normal breast can be easily recognized by unsupervised algorithms, the difference between those two types of tumours is more discrete. However, by supervised methods of data analysis, we were able to select a set of genes that may differentiate between hereditary and sporadic tumours. The most significant difference concerns genes that code for proteins engaged in regulation of transcription, cellular metabolism, signalling, proliferation and cell death. Microarray results for chosen genes (TOB1, SEPHS2) were validated by real-time RT-PCR. PMID:20223001

    A Phase 1 Preliminary Design, Construction Planning and Economic Analysis has been conducted for the Kelly Hot Spring Agricultural Center in Modoc County, California. The core activity is a 1360 breeding sow, swine raising complex that utilizes direct heat energy from the Kelly Hot Spring geothermal resource. The swine is to be a totally confined operation for producing premium pork in controlled-environment facilities. The complex contains a feed mill, swine raising buildings and a complete waste management facility that produces methane gas to be delivered to a utility company for the production of electricity. The complex produces 6.7 million pounds of live pork (29,353 animals) shipped to slaughter per year; 105,000 cu. ft. of scrubbed methane per day; and fertilizer. Total effluent is less than 200 gpm of agricultural quality-water with full odor control. The methane production rate made possible with geothermal direct heat is equivalent to at least 400 kw continuous. Sale of the methane on a co-generation basis is being discussed with the utility company. The use of geothermal direct heat energy in the complex displaces nearly 350,000 gallons of fuel oil per year. Generation of the biogas displaces an additional 300,000 gallons of fuel oil per year.

    Extrinsic discoloration of teeth following a large consumption of tannin-containing beverages or a prolonged use of chlorhexidine mouthrinses is a well known observation. Tannins as well as chlorhexidine are denaturing agents. Based on preliminary studies revealing the presence of iron in chlorhexidine discolored pellicle material, the ability of iron to stain the integument after pretreatment with the two denaturants was studied in a human model. The denaturing effect of an acidic environment was also included. Enamel slabs fixed to acrylic appliances were carried in the oral cavity and alternately exposed to the test solutions in different sequences in vitro. Pretreatment with chlorhexidine or tannic acid led to marked discoloration upon iron application during 5-d tests, whereas the compounds individually had no such effect. A large content of the metal was found in the stained material. Stannous fluoride appeared to reduce the formation of the pigments, and strong oxidation completely bleached the established color. Possible mechanisms underlying the phenomena observed are discussed.

    Colostomy is conventionally the only treatment for anal dysfunction. Recently, a few trials of anorectal transplantation in animals have been published; however, further development of this technique is required. Moreover, it is crucial to perform this research in dogs, which resemble humans in anorectal anatomy and biology. We designed a canine anorectal transplantation model, wherein anorectal autotransplantation was performed by anastomoses of the rectum, inferior mesenteric artery (IMA) and vein, and pudendal nerves. Resting pressure in the anal canal and anal canal pressure fluctuation were measured before and after surgery. Graft pathology was examined three days after surgery. The anal blood supply was compared with that in three beagles using indocyanine green (ICG) fluorescence angiography. The anorectal graft had sufficient arterial blood supply from the IMA; however, the graft’s distal end was congested and necrotized. Functional examination demonstrated reduced resting pressure and the appearance of an irregular anal canal pressure wave after surgery. ICG angiography showed that the pudendal arteries provided more blood flow than the IMA to the anal segment. This is the first canine model of preliminary anorectal autotransplantation, and it demonstrates the possibility of establishing a transplantation model in dogs using appropriate vascular anastomoses, thus contributing to the progress of anorectal transplantation.

    The experience of self is unique and pivotal to clinically relevant cognitive and emotional functions. However, well-controlled data on specialized brain regions and functional networks underlying the experience of self remain limited. This functional magnetic resonance imaging study investigated neural activity and connectivity specific to processing one's own face in healthy women by examining neural responses to the pictures of the subjects' own faces in contrast to faces of their own mothers, female friends and strangers during passive viewing, emotional and self-relevance evaluations. The processing of one's own face in comparison to processing of familiar faces revealed significant activity in right anterior insula (AI) and left inferior parietal lobule (IPL), and less activity in right posterior cingulate/precuneus (PCC/PCu) across all tasks. Further, the seed-based correlation analysis of right AI, and left IPL, showed differential functional networks in self and familiar faces contrasts. There were no differences in valence and saliency ratings between self and familiar others. Our preliminary results suggest that the self-experience cued by self-face is processed predominantly by brain regions and related networks that link interoceptive feelings and sense of body ownership to self-awareness and less by regions of higher order functioning such as autobiographical memories.

    The FMC Pesticide Pit (FMC) is on the National Priorities List. FMC, a former pesticide-formulation facility, disposed of wastes in an unlined pit area from 1952 to 1969. Preliminary on-site sampling results have identified pesticides and herbicides present in all soil. They include various organochlorines such as aldrin (1 to 110 ppm), benzene hydrochloride (BHC) (1 to 2,000 ppm), DDT (1 to 120,000), Ovex (1 to 19,000 ppm), and organophosphate compounds such as ethion (1 to 12,000), and ethyl parathion (1 to 16,000 ppm). In addition, carbamates were detected as carbaryl (1 to 1,800 ppm), and chromium (6 to 440 ppm) was also found. On-site ground water monitoring data demonstrated concentrations of BHC (0.04 to 0.09 ppb), DDT derivatives (0.02 to 9.9 ppb), endosulfan isomers (0.02 to 1.1 ppb), and derivatives (0.02 to 9.9 ppb), endosulfan isomers (0.02 to 1.1 ppb), and acetone (17 to 16,000 ppb). The site is considered to be of potential public health concern because of exposure to contaminated ground water. However, there are other pesticide manufacturing plants in the area that probably contribute to the off-site ground water contamination.

    Neuropathic pain models are classified as central and peripheral pain models. Although various peripheral neuropathic pain models are established, central pain models are based only on spinal cord injury. DSP-4 is a competitive inhibitor of norepinephrine uptake that selectively degenerates the locus coeruleus (LC)-noradrenergic neurons projection to the cerebral cortex and hippocampus. In the present study, we have tested whether lesion of LC-noradrenergic neurons by ip DSP-4 (0, 10, 30, 50 mg/kg, n=7 each) could provide a new central neuropathic pain model in rats using a hot-plate and tail-flick tests. DSP-4 significantly reduced the hot-plate latency and norepinephrine contents especially in the coerulean regions. However, DSP-4 did not change tail-flick latency. There are significant correlations of the latency in the hot-plate test with norepinephrine contents in the cerebral cortex (r=0.432, p=0.022), the hippocampus (r=0.465, p=0.013) and the pons (r=0.400, p=0.035) but not with those in the hypothalamus and the spinal cord. As response to hot-plate and tail-flick implies supra-spinal process and spinal reflex, respectively, central neuropathic pain may be facilitated by DSP-4 depleting LC-noradrenergic neurons although the present data are preliminary.

    Intensive chemotherapy programme in children with cancer may result in psychological mal adjustment. Treatment facilities as well as psychological support are of great importance to minimize these side effects. In 1998 the programme of psychological support was introduced in 7 Polish paediatric haematology / oncology centres. Psychological adjustment of patients treated in each centre was examined 5 yrs after the termination of therapy. At the same time children with new diagnosis of cancer were monitored psychologically along with the psychological support programme. Psychological status of each patient was examined with the following tests: Cattell's questionnaires (CPQ, HSPQ), Manifest Anxiety Scale, Spielberger's inventories (STAI, STAIC), Wechsler Intelligence Scale. The programme of psychological support was based on guidelines of SIOP Psychosocial Committee and included such elements as informing about diagnosis and treatment, explaining any doubt, maintaining an open communication, educational care in the periods of treatment, encouraging to activity even during periods of discomfort. The analysis showed that most of the participating centres could only provide some elements of the support programme. The main problem was to convince medical staff to inform children on diagnosis and treatment plans. Preliminary results of the study indicate that full psychological support for children with cancer and their families from the beginning of therapy can result in improvement in psychological adjustment. During the ensuing period, patients and their parents appreciate the possibilities to contact a psychologist.

Serum levels of otolin-1, P1NP, NTX, vitamin D, and calcium were examined in relation to each other, age, and DEXA scan T-scores. There was a strong, negative correlation between T-scores and otolin-1 levels. Although P1NP and NTX levels were strongly correlated, neither had statistical correlations with otolin-1. Despite a strong correlation between DEXA scan results and otolin-1 levels, there were no significant correlations between otolin-1 and P1NP or NTX. This suggests that the association between osteoporosis and BPPV is complex, but not likely to be causal. Although more work is needed to elucidate these relationships, this preliminary finding has important practical implications for BPPV in that proactive management of osteoporosis, per se, would not be expected to have benefits in management of BPPV.

    Aim: To compare the effects of aliskiren, ramipril, and losartan on the psychomotor performance in healthy volunteers. Materials and Methods: In this preliminary, single-dose, open-label, cross-over study conducted in 12 healthy volunteers, psychomotor assessment was carried out by four tests: Simple reaction time (SRT), multiple choice reaction time test (MCRT), critical flicker fusion frequency threshold test (CFFT), and tracking performance test (TPT). Each volunteer received a single dose of each of the three test drugs with a washout period of 10 days between different test sessions and then evaluated for post-drug scores at 2-h intervals up to 12 h and then at 24 h. The changes from the baseline scores by the test drug were statistically analyzed. Results: All the three antihypertensive drugs caused significant improvement in a similar fashion on SRT, MCRT calculated as error index, CFFT, and TPT. Aliskiren caused numerically more improvement than the other two test drugs, suggesting better cognitive profile. However, inter-drug comparisons were nonsignificant. Conclusion: The results of the study highlight improvement of the cognitive functions equally by ramipril, losartan, and aliskiren. The results of the study could be of immense clinical utility in ambulatory hypertensive patients especially engaged in sensory-motor coordination tasks like driving and operating on mechanical tools.

    The objective of this preliminary study was to determine if the occlusal contact surface registered with an articulating paper during fixed prosthodontic treatment was contained within the area marked on a thicker articulating paper. This information would optimize any necessary occlusal adjustment of a prosthesis' veneering material. A convenience sample of 15 patients who were being treated with an implant-supported fixed singleunit dental prosthesis was selected. Occlusal registrations were obtained from each patient using 12-μm, 40-μm, 80-μm, and 200-μm articulating paper. Photographs of the occlusal registrations were obtained, and pixel measurements of the surfaces were taken and overlapped for comparison. The results showed that the thicker the articulating paper, the larger the occlusal contact area obtained. The differences were statistically significant. In all cases, the occlusal registrations obtained with the thinnest articulating paper were contained within the area marked on the thickest articulating paper. The results suggested that the use of thin articulating papers (12-μm or 40-μm) can avoid unnecessary grinding of veneering material or teeth during occlusal adjustment.

    The preliminary design of the Solar Thermal Enhanced Oil Recovery (SolarOil) Plant is described in this document. This plant is designed to demonstrate that using solar thermal energy is technically feasible and economically viable in enhanced oil recovery (EOR). The SolarOil Plant uses the fixed mirror solar concentrator (FMSC) to heat high thermal capacity oil (MCS-2046) to 322/sup 0/C (611/sup 0/F). The hot fluid is pumped from a hot oil storage tank (20 min capacity) through a once-through steam generator which produces 4.8 MPa (700 psi) steam at 80% quality. The plant net output, averaged over 24 hr/day for 365 days/yr, is equivalent to that of a 2.4 MW (8.33 x 10/sup 6/ Btu/hr) oil-fired steam generator having an 86% availability. The net plant efficiency is 57.3% at equinox noon, a 30%/yr average. The plant will be demonstrated at an oilfield site near Oildale, California.

    To help stem cult activities on campuses by identifying motives for joining cult groups and highlighting psychosocial attributes/profile of a potential or already initiated cult member. Using snow-balling method, 25 consecutive consenting cult members of University of Ilorin were interviewed over a six month period using a semi-structured questionnaire. Those who had symptoms suggestive of psychiatric disorders were further assessed based on ICD-10 criteria. All patients with previous psychiatric illness were excluded. A significant proportion of the respondents were first year, male, previously shy students from high socioeconomic background. There was a significant increase in the proportion of respondents who had palpitation, sweated more, felt bolder, and became current users of alcohol and tobacco after initiation. Also, there was a significant decrease in the proportion of respondents who slept well, felt accepted by friends and performed well in academic activities after initiation. In spite of the small sample size and method of data collection, the preliminary findings in this study, could be useful in stemming the increasing menace of cultism among students in tertiary institutions. It was suggested that control of cult activities should be multidimensional with students, parents and university administration taking active parts. Establishment of 'Help Centres' on campuses was suggested.

    Surveys from several countries have identified the presence of risk factors known to be associated with coronary heart disease in children. Data on the distribution of coronary risk factor variables in British children are scarce. This study was therefore designed to test the feasibility of collecting coronary risk factor data from British children and to conduct a preliminary examination of the problem. One hundred and seven children (mean age 12.8 yr) had their height, weight, triceps skinfold and blood pressure checked. Blood samples for cholesterol and HDL-cholesterol analysis were obtained from 93 children. Peak VO2 was determined on 48 children, 76 children had their daily activity monitored and 59 children's stage of sexual maturity was assessed. The boys' peak VO2 was significantly higher than the girls, whether expressed in l.min-1 (p less than 0.05) or ml.kg.-1min-1 (p less than 0.01). No other significant differences (p greater than 0.05) between the sexes were detected. The results indicate that children have relatively high serum cholesterol levels (boys 4.58 +/- 0.79; girls 4.72 +/- 0.80 mmol.l-1). The willingness and enthusiasm of the children, parents and schools to take part in the study clearly demonstrated the feasibility of a large scale study being successfully pursued in the United Kingdom.

    Objectives We report the preliminary development of a unique Web-based instrument for assessing and teaching knowledge and developing clinical thinking called the “Sequential Questions and Answers” (SQA) test. Included in this feasibility report are physicians’ answers to the Sequential Questions and Answers pre- and posttests and their brief questionnaire replies. Methods The authors refined the SQA test case scenario for content, ease of modifications of case scenarios, test uploading and answer retrieval. Eleven geographically distant physicians evaluated the SQA test, taking the pretest and posttest within two weeks. These physicians completed a brief questionnaire about the SQA test. Results Eleven physicians completed the SQA pre- and posttest; all answers were downloaded for analysis. They reported the ease of website login and navigating within the test module together with many helpful suggestions. Their average posttest score gain was 53% (p=0.012). Conclusions We report the successful launch of a unique Web-based instrument referred to as the Sequential Questions and Answers test. This distinctive test combines teaching organization of the clinical narrative into an assessment tool that promotes acquiring medical knowledge and clinical thinking. We successfully demonstrated the feasibility of geographically distant physicians to access the SQA instrument. The physicians’ helpful suggestions will be added to future SQA test versions. Medical schools might explore the integration of this multi-language-capable SQA assessment and teaching instrument into their undergraduate medical curriculum. PMID:25341203

    Vadose zone investigations are being performed at site S-7 in IC 34, at McClellan AFB. At this location, a Vadose Zone Monitoring System (VZMS) is being used to collect subsurface data including hydraulic potential, soil gas pressure, moisture content, water chemistry, gas chemistry, and temperature. Although each individual data set is useful in improving the characterization of this contaminated site, the overall purpose of data collection is to provide input for the conceptual and numerical modeling of VOC transport in the vadose zone and the exchange of contaminants between the vadose zone and groundwater. In this report the authors submit a summary and preliminary analysis of the data collected through the end of 1997 and present it in the context of input for the impending modeling. This report merges findings from both the first and second half of 1997 and is presented as an annual report in lieu of two semi-annual reports, due to the fact that insufficient data had been collected up to mid June to allow a meaningful analysis.

    The National Coal Resource Assessment (NCRA) project by the U.S. Geological Survey is designed to assess US coal with the greatest potential for development in the next 20 to 30 years. Coal in the Wyodak-Anderson (WA) coal zone in the Powder River Basin of Wyoming and Montana is plentiful, clean, and compliant with EPA emissions standards. This coal is considered to be very desirable for development for use in electric power generation. The purpose of this NCRA study was to compile all available data relating to the Wyodak- Anderson coal, correlate the beds that make up the WA coal zone, create digital files pertaining to the study area and the WA coal, and produce a variety of reports on various aspects of the assessed coal unit. This report contains preliminary calculations of coal resources for the WA coal zone and is one of many products of the NCRA study. Coal resource calculations in this report were produced using both public and confidential data from many sources. The data was manipulated using a variety of commercially available software programs and several custom programs. A general description of the steps involved in producing the resource calculations is described in this report.

    The study examined the use of computer-mediated communication (CMC) among individuals involved in a conflict sparked by the appointment of an administrator as president-designate of Gallaudet University in 2006. CMC was defined as forms of communication used for transmitting (sharing) information through networks with digital devices. There were 662 survey respondents. Respondents reported overwhelmingly (98%) that they used CMC to communicate. Students and alumni reported CMC use in larger proportions than any other group. The favorite devices among all respondents were Sidekicks, stationary computers, and laptops. Half of all respondents also reported using some form of video device. Nearly all reported using e-mail; respondents also identified Web surfing, text messaging, and blogging as popular CMC activities. The authors plan another article reporting on computer and electronic technology use as a mechanism connecting collective identity to social movements.

    Distraction osteogenesis is a useful alternative to advance the maxilla in complicated cases of maxillary hypoplasia. The purpose of this article is to review the workup, experience, and preliminary results with the use of internal distraction osteogenesis for maxillary hypoplasia at one teaching institution. Over a 5-year period, more than 300 patients with craniofacial and dentofacial defects have undergone oral and maxillofacial surgery at our center to correct their skeletal discrepancies. Of these, 10 have had maxillary distraction osteogenesis done with internal distractors. Follow-up of 6 months or more was available for 8 patients. Stereolithographic models were used to bend distractors prior to surgery in 6 patients. Latency prior to the start of distraction was 3 to 7 days and varied with the age of the patient. Distraction occurred at approximately 1 mm per day with an average distraction length of 8.5 mm (range, 6-10 mm). Excellent occlusal results were obtained in 5 patients. Major complications including nonunion and failure to achieve acceptable occlusal results were observed in 3 patients. Minor complications including pain and loosening of the distracter devices were observed in 2 patients, but did not appear to affect the esthetic and functional results. Distraction osteogenesis is a useful alternative to traditional orthognathic surgery to treat maxillary hypoplasia. Internal distractions are attractive to patients, but are more difficult to place and can cause discomfort to patients when trying to achieve an ideal primary vector of distraction. Stereolithographic models can help with placement of the device. Changes in design of distractors may help with patient discomfort.

    Study Design Prospective clinical study. Purpose To observe the usefulness of anterior cervical osteophytes as intrinsic markers for spinal level localization (SLL) during sub-axial cervical spinal surgery via the anterior approach. Overview of Literature Various landmarks, such as the mandibular angle, hyoid bone, thyroid cartilage, first cricoid ring, and C6 carotid tubercle, are used for gross cervical SLL; however, none are used during cervical spinal surgery via the anterior approach. We present our preliminary assessment of SLL over anterior vertebral surfaces (i.e., intrinsic markers) in 48 consecutive cases of anterior cervical spinal surgeries for the disc-osteophyte complex (DOC) in degenerative diseases and granulation or tumor tissue associated with infectious or neoplastic diseases, respectively, at an ill-equipped center. Methods This prospective study on patients undergoing anterior cervical surgery for various sub-axial cervical spinal pathologies aimed to evaluate the feasibility and accuracy of SLL via intraoperative palpation of disease-related morphological changes on anterior vertebral surfaces visible on preoperative midline sagittal T1/2-weighted magnetic resonance images. Results During a 3-year period, 48 patients (38 males,10 females; average age, 43.58 years) who underwent surgery via the anterior approach for various sub-axial cervical spinal pathologies, including degenerative disease (n= 42), tubercular infection (Pott's disease; n=3), traumatic prolapsed disc (n=2), and a metastatic lesion from thyroid carcinoma (n=1), comprised the study group. Intrinsic marker palpation yielded accurate SLL in 79% of patients (n=38). Among those with degenerative diseases (n=42), intrinsic marker palpation yielded accurate SLL in 76% of patients (n=32). Conclusions Intrinsic marker palpation is an attractive potential adjunct for SLL during cervical spinal surgeries via the anterior approach in well-selected patients at ill-equipped centers (e

    Prior to disposal, nuclear waste must be accurately characterized to identify and quantify the radioactive content to reduce the radioactive hazard to the public. Validation of the waste-assay systems` performance is critical for establishing the credibility of the assay results for storage and disposal purposes. Canberra Nuclear has evaluated regulations worldwide and identified standard, modular, neutron- and gamma-waste-assay systems that can be used to characterize a large portion of existing and newly generated transuranic (TRU) and low-level waste. Before making claims or guaranteeing any system`s performance for specific waste types, the standardized systems` performance must be evaluated. Canberra and Los Alamos National Laboratory`s (LANL) Plutonium Facility developed a three-phase validation plan. During Phase One, tests were performed using simulation sources at Canberra to determine the error bounds for measurement parameters, to determine the minimum detectable activity, and to measure precision and bias. During Phase Two, two mobile systems were installed at the Plutonium Facility. LANL is providing peer review of the systems` performance for plutonium, acting as a beta test site to evaluate the waste-assay software, and providing data for {open_quotes}precertification{close_quotes} at future Department of Energy installations. (Plutonium isotopics are determined from measurements using the Multi-Group Analysis code.) Finally, the two systems` performances are evaluated for representative waste types (salt, metal, combustibles, leaded rubber, and HEPA filters). Phase Three of the validation, the Waste Isolation Pilot Plant Performance Demonstration Plan, will require approval by the National TRU Program Office. This paper describes the standard mobile waste-assay systems, the test plan, and preliminary results from the peer review outlined above in Phase Two.

    Clinical trials of analgesics have been plagued with poor assay sensitivity due, in part, to variability in subjects’ pain reporting. Herein, we develop and evaluate the focused analgesia selection test (FAST), a method to measure patients’ pain reporting skills. Subjects with osteoarthritis of the hip, knee, and/or ankle with pain intensity of ≥3/10 on a 0–10 numerical rating scale were enrolled. Subjects underwent the FAST procedure, which consists of recording subjects’ pain reports in response to repeated administration of thermal noxious stimuli of various intensities applied on the arm with the Medoc® Thermal Sensory Analyzer II. Subjects also rated non-noxious stimuli consisting of visual contrast rating. After performing an exercise task, subjects also rated clinical pain and were asked to report whether their pain had increased, decreased, or stayed the same. Overall, 88 subjects were enrolled, and 83 were included in the analyses. FAST’s outcomes including the R2, intraclass correlation coefficient (ICC), and coefficient of variation (CoV) indicated that subjects’ pain reporting skills were widely distributed. Higher FAST ICC significantly predicted greater changes in clinical pain following exercise (p=0.017), whereas the visual contrast test did not predict postexercise pain. FAST is the first method that measures subjects’ pain reporting skills. Using FAST to enrich clinical trials with “good” pain reporters (with high FAST ICC) could increase assay sensitivity. Further evaluation of FAST is ongoing. PMID:28243138

    In Colombia, approximately 105,000 suspected cases of Zika virus disease (diagnosed based on clinical symptoms, regardless of laboratory confirmation) were reported during August 9, 2015-November 12, 2016, including nearly 20,000 in pregnant women (1,2). Zika virus infection during pregnancy is a known cause of microcephaly and serious congenital brain abnormalities and has been associated with other birth defects related to central nervous system damage (3). Colombia's Instituto Nacional de Salud (INS) maintains national surveillance for birth defects, including microcephaly and other central nervous system defects. This report provides preliminary information on cases of congenital microcephaly identified in Colombia during epidemiologic weeks 5-45 (January 31-November 12) in 2016. During this period, 476 cases of microcephaly were reported, compared with 110 cases reported during the same period in 2015. The temporal association between reported Zika virus infections and the occurrence of microcephaly, with the peak number of reported microcephaly cases occurring approximately 24 weeks after the peak of the Zika virus disease outbreak, provides evidence suggesting that the period of highest risk is during the first trimester of pregnancy and early in the second trimester of pregnancy. Microcephaly prevalence increased more than fourfold overall during the study period, from 2.1 per 10,000 live births in 2015 to 9.6 in 2016. Ongoing population-based birth defects surveillance is essential for monitoring the impact of Zika virus infection during pregnancy on birth defects prevalence and measuring the success in preventing Zika virus infection and its consequences, including microcephaly.

    Rural community mental health centers (CMHCs) face numerous problems that might be alleviated by the dissemination of empirically supported treatments (ESTs). The current study lays the groundwork for EST dissemination by examining current treatment practices in rural clinics as well as the attitudes of decision makers toward ESTs and perceived barriers to their adoption. Twenty-five rural and 38 non-rural clinical directors responded to a mailed survey. Rural respondents were as likely as non-rural respondents to report EST use in their clinic for most anxiety disorders, and more likely to report use of an EST for major depressive disorder and obsessive-compulsive disorder. However, ESTs represent a relatively small proportion of the treatments reported for depression and anxiety disorders. Attitudes toward manualized ESTs did not differ between groups. Further, rural and nonrural clinics did not see the barriers to the adoption of ESTs as insurmountable. These preliminary results suggest that rural CMHCs are open to the use of ESTs and should be included in widespread dissemination initiatives.

    Radiofrequency-induced heating of dermal and subdermal tissue promotes skin contracture; however, the temperature threshold for inducing an epidermal burn is lower than the therapeutic temperature thresholds required for collagen remodeling, and therefore, there is the possibility of epidermal burn. Herein, we evaluate a radiofrequency treatment that provides novel real-time subdermal and epidermal temperature monitoring. A retrospective chart review of 18 subjects undergoing thermistor-controlled subdermal skin tightening via percutaneous radiofrequency was conducted. During the treatment, epidermal temperature was concurrently monitored by a handheld infrared laser thermometer and a forward looking infrared camera system and peak temperatures readings were reported and evaluated. Mean temperatures of 43.6 and 38.2°C were reported for the infrared camera and infrared thermometer. The Bland-Altman plot analysis reported a bias of 5.38°C and 95% limits of agreement between 0.60 and 10.15°C. Additionally, the mean difference or bias of 5.38°C was statistically significant (P<0.0001. Our preliminary data supports a superior form of thermoregulation for the purposes of skin tightening that integrates continuous subsurface and epidermal temperature monitoring.

    Background Distal radius fracture is the most common fracture of the upper extremity, and approximately 60,000 distal radius fractures occur annually in Korea. Internal fixation with an anatomical volar locking plate is widely used in the treatment of unstable distal radius fractures. However, most of the currently used distal radius anatomical plate systems were designed based on the anatomical characteristics of Western populations. Recently, the Korean-type distal radius anatomical volar plate (K-DRAVP) system was designed and developed based on the anatomical characteristics of the distal radius of Koreans. The purpose of this study was to evaluate the preliminary results of the new K-DRAVP system, and to compare its radiologic and functional results with those of the other systems. Methods From March 2012 to October 2012, 46 patients with acute distal radius fractures who were treated with the K-DRAVP system at three hospitals were enrolled in this study. Standard posteroanterior and lateral radiographs were obtained to assess fracture healing, and three radiographic parameters (volar tilt, radial inclination, and radial length) were assessed to evaluate radiographic outcomes. The range of motion and grip strength, the Gartland and Werley scoring system, and the disabilities of the arm, shoulder and hand (DASH) questionnaire were used to assess clinical and functional outcomes. Results All radiologic parameters were restored to normal values, and maintained without any loosening or collapse until the time of final follow-up. Grip strength was restored to 84% of the value for the unaffected side. The mean range of motion of the wrist at final follow-up was restored to 77%-95% of the value for the unaffected side. According to the Gartland and Werley scoring system, there were 16 excellent, 26 good, and 4 fair results. The mean DASH score was 8.4 points. There were no complications after surgery. Conclusions The newly developed K-DRAVP system could be used to

    hypermethylation of the CpG islands flanking a CRE and SP1 binding site observed at a significantly higher level (t = -5.07, P = 0.001) may provide a mechanism for the decreased RELN expression, frequently observed in post-mortem brains of schizophrenic patients. We also found an inverse relationship between the level of DNA methylation using MSP analysis and the expression of the RELN gene using semi-quantitative RT-PCR. Despite the small sample size, these studies indicate that promoter hypermethylation of the RELN gene could be a significant contributor in effecting epigenetic alterations and provides a molecular basis for the RELN gene hypoactivity in schizophrenia. Further studies with a larger sample set would be required to validate these preliminary observations.

    Many athletes continue to participate in practices and games while experiencing concussion-related symptoms, potentially predisposing them to subsequent and more complicated brain injuries. Limited evidence exists about factors that may influence concussion-reporting behaviors. To examine the influence of knowledge and attitude on concussion-reporting behaviors in a sample of high school athletes. Cross-sectional study. Participants completed a validated survey instrument via mail. A total of 167 high school athletes (97 males, 55 females, 5 sex not indicated; age = 15.7 ± 1.4 years) participating in football, soccer, lacrosse, or cheerleading. Athlete knowledge and attitude scores served as separate predictor variables. We examined the proportion of athletes who reported continuing to participate in games and practices while symptomatic from possible concussion and the self-reported proportion of recalled concussion and bell-ringer events disclosed after possible concussive injury. Only 40% of concussion events and 13% of bell-ringer recalled events in the sample were disclosed after possible concussive injury. Increased athlete knowledge of concussion topics (increase of 1 standard deviation = 2.8 points) was associated with increased reporting prevalence of concussion and bell-ringer events occurring in practice (prevalence ratio [PR] = 2.27, 95% confidence interval [CI] = 1.60, 3.21) and the reporting prevalence of bell-ringer-only events overall (PR = 1.87, 95% CI = 1.38, 2.54). Athlete attitude scores (increase of 1 standard deviation = 11.5 points) were associated with decreases in the proportion of athletes stating they participated in games (PR = 0.74, 95% CI = 0.66, 0.82) and practices (PR = 0.67, 95% CI = 0.59, 0.77) while symptomatic from concussions. Most recalled concussion events in our study were not reported to a supervising adult. Clinicians should be aware that knowledge and attitude influence concussion reporting.

    There are no published data on typical phonological development for Singaporean children. There is therefore the risk that children's speech in Singapore may be misdiagnosed or that clinicians may set goals erroneously. This paper reports a preliminary study on the English phonology of typically developing 4;0-4;5-year-old Chinese Singaporean children who speak English and Mandarin. Seventy children were recruited throughout Singapore, and speech samples were collected in English using the Phonology Assessment of the Diagnostic Evaluation of Articulation and Phonology (DEAP). The participants were divided equally into two groups: English-dominant and Mandarin-dominant. Their speech samples were compared with British English targets (BT) and Singapore English targets (ST) in terms of phonological accuracy and types of phonological processes used. The results showed that Singaporean children's phonological accuracy scores increased significantly when scored against ST instead of BT. When scored against ST, English-dominant children were found to perform similarly to their DEAP counterparts. However, Mandarin-dominant children had significantly less accurate consonant production in English and exhibited more interference effects from Mandarin phonology than English-dominant children. In this preliminary study, the results highlight the importance of speech and language therapists using local dialect pronunciations to be the target of speech assessments so as to provide appropriate assessment and intervention. It is also essential to account for the language background and language dominance of the children. More local normative data are needed for the typical acquisition of Singapore English in children, especially for children whose dominant language is not English. © 2014 Royal College of Speech and Language Therapists.

    In an on-going endotoxin assay study, a two-part interlaboratory endotoxin assay study has been completed. The purpose of the study was to compare the variation in assay results between different laboratories, and, if the variation was high, to see if a common protocol would reduce the variation. In both parts of the study, membrane filters laden with the same approximate amount and type of cotton dust were sent for analysis to laboratories that "routinely" perform endotoxin analyses. First, each of these laboratories performed the analysis using the methodology common to its laboratory. In the second part of the study, membrane filters with cotton dust were again sent to the same laboratories where the analyses were performed as before but with a common extraction protocol. The preliminary results from the first phase of the study have been collected and showed that intra-laboratory variations were small, but large and significant interlaboratory variation was observed. The results were reported elsewhere. The preliminary results from the second part of the study consisting of the data currently collected are presented here. Again, intra-laboratory variations were small, but, also again, large and significant inter-laboratory variation was observed. However, in this part of the study, the range between the highest and lowest average results was narrower than in the first part of the study. Influence of the assay kit type was examined. The variation within assay kit type was small but significant differences in results were observed between assay kit types. The findings suggest that endotoxin concentration in samples can be ranked within laboratories, but not necessarily between laboratories. However, some of the variation between laboratories has been reduced by a common extraction protocol which suggests the possibility of further standardization that may lead to better comparability between laboratories.

  2. Functional challenges among late effects cancer survivors: a preliminary report on work engagement issues.

    2013-01-01

    While the cancer survivor rate is nearly 68% now, intervention regimens may leave residual conditions that impact engagement in work and various life tasks. Survivors are underemployed and report stigmatizing attitudes among co-workers. When late effects from cancer arise over 10 years later, the impact on individuals in the prime of their productive employment life is evident. Assisting these individuals begins with awareness of late effects in order to create work-related, adaptive strategies. Sixteen adult cancer survivors experiencing late effects completed the Occupational Self Assessment (Version 2.2) and the Quality of Life-Cancer Survivors (QOL-CS). Knowledge of functional problems secondary to recognized late effects medical conditions reported in the literature was utilized to sort items according to professional definitions of work, performance skills and performance patterns. Late effects survivors reported that cancer illness and treatment has negatively impacted their employment. Individual response to the impact of late effects is highly variant. "Getting things done" and physical energy limitations are most pronounced. Cancer survivors report lower competence in significant work-related skills and patterns. Quality of life associated with the aftereffects of fatigue, aches and pain, and sleep changes are the lowest. Responses range across the 16 survivors to both performance skills and performance patterns. Cancer survivorship has clearly interfered with employment. An interdisciplinary focus on meaningful engagement in life activities, particularly work is crucial to support survivors through advocacy, adaptation and positive change to focus on engaging the work talents and gifts for all cancer survivors.

    Sacral nerve stimulation is a widely accepted therapeutic option for neurogenic fecal incontinence. More recently, case reports showed a positive effect of sacral nerve stimulation in patients with fecal incontinence following low anterior resection. The purpose of this study was to gain more information for this selected indication for sacral nerve stimulation through a nationwide survey. In the period 2002 to 2005, three Austrian departments reported data of patients who underwent SNS for fecal incontinence following rectal resection. Data were available of seven patients (two female, five male) with a median age of 57 years (min 42; max 79). Six patients had undergone rectal resection as a treatment for low rectal cancer. One patient had undergone rectal resection for Crohn's disease, one patient subtotal colectomy and ileorectostomy for slow colon transit constipation. Test stimulation was performed in the foramen S3 unilaterally over a median period of 14 days (2-21 days). Seven patients reported a marked reduction of episodes of incontinence during the observation period and received a permanent stimulation system. After a median follow-up of 32 months (17-46), five patients reported a marked improvement of their continence situation. Despite a nationwide survey experiences with SNS as a treatment for fecal incontinence following rectal resection is still limited. Our observations show an improvement of the continence function following SNS. However, the promising results of our series as well as others need further research and more clinical data by a larger number of patients in a prospective trial.

    Objective To ascertain whether level of intrauterine cocaine exposure (IUCE) is associated with early adolescent delinquent behavior, after accounting for prenatal exposures to other psychoactive substances and relevant psychosocial factors. Methods Ninety-three early adolescents (12.5–14.5 years old) participating since birth in a longitudinal study of IUCE reported delinquent acts via an audio computer assisted self interview (ACASI). Level of IUCE and exposure to cigarettes, alcohol, and marijuana were determined by maternal report, maternal and infant urine assays, and infant meconium assays at birth. Participants reported their exposure to violence on the Violence Exposure Scale for Children – Revised (VEX-R) at ages 8.5, 9.5, 11 years and during early adolescence, and the strictness of supervision by their caregivers during early adolescence. Results Of the 93 participants, 24 (26%) reported ≥3 delinquent behaviors during early adolescence. In the final multivariate model (including level of IUCE and cigarette exposure, childhood exposure to violence, and caregiver strictness/supervision) ≥ 3 delinquent behaviors were not significantly associated with level of IUCE but were significantly associated with intrauterine exposure to half a pack or more of cigarettes per day and higher levels of childhood exposure to violence, effects substantially unchanged after control for early adolescent violence exposure. Conclusions In this cohort, prospectively ascertained prenatal exposure to cigarettes and childhood exposure to violence are associated with self-reported delinquent behaviors during early adolescence. Contrary to initial popular predictions, intrauterine cocaine is not a strong predictor of adolescent delinquent behaviors in this cohort. PMID:21558951

    This report presents the preliminary findings of the first phase of the Environmental Survey of the United States Department of Energy's (DOE) Idaho National Engineering Laboratory (INEL) and Component Development and Integration Facility (CDIF), conducted September 14 through October 2, 1987. The Survey is being conducted by an interdisciplinary team of environmental specialists, led and managed by the Office of Environment, Safety and Health's Office of Environmental Audit. The team includes outside experts supplied by a private contractor. The objective of the Survey is to identify environmental problems and areas of environmental risk associated with the INEL and CDIF. The Survey covers all environmental media and all areas of environmental regulation. It is being performed in accordance with the DOE Environmental Survey Manual. The on-site phase of the Survey involves the review of existing site environmental data, observations of the operations' carried on at the INEL and the CDIF, and interviews with site personnel. The Survey team developed a Sampling and Analysis (S A) Plan to assist in further assessing certain of the environmental problems identified during its on-site activities. The S A Plan will be executed by the Oak Ridge National Laboratory. When completed, the S A results will be incorporated into the INEL/CDIF Survey findings for inclusion into the Environmental Survey Summary Report. 90 refs., 95 figs., 77 tabs.

    The following is a report on the findings of a documentary literature search on the ahupuaa of Kahauale'a in the Puna District of the island of Hawaii. Attention is given to the entirety of the ahupuaa, though the emphasis is on the mauka portions from about 1,500 to 3,800-feet elevation, or roughly three miles inland to the northern terminus of the ahupuaa, just below Kilauea. The report was commissioned by The Estate of James Campbell for purposes of ascertaining what the extent of early Hawaiian activities and/or habitation occurred in the mauka regions of Kahauale'a--specifically to see if proposed geothermal drilling activities in these areas would disturb any archaeological sites.

    Incident reporting systems are universally recognized as important tools for quality improvement in all complex adaptive systems, including the operating room. Nevertheless, introducing a safety culture among neurosurgeons is a slow process, and few studies are available in the literature regarding the implementation of an incident reporting system within a neurosurgical department. The authors describe the institution of an aviation model of incident reporting and investigation in neurosurgery, focusing on the method they have used and presenting some preliminary results. In 2010, the Inpatient Safety On-Board project was developed through cooperation between a team of human factor and safety specialists with aviation backgrounds (DgSky team) and the general manager of the Fondazione Istituto Neurologico Carlo Besta. In 2011, after specific training in safety culture, the authors implemented an aviation-derived prototype of incident reporting within the Department of Neurosurgery. They then developed an experimental protocol to track, analyze, and categorize any near misses that happened in the operating room. This project officially started in January 2012, when a dedicated team of assessors was established. All members of the neurosurgical department were asked to report near misses on a voluntary, confidential, and protected form (Patient Incident Reporting System form, Besta Safety Management Programme). Reports were entered into an online database and analyzed by a dedicated team of assessors with the help of a facilitator, and an aviation-derived root cause analysis was performed. Since January 2012, 14 near misses were analyzed and classified. The near-miss contributing factors were mainly related to human factors (9 of 14 cases), technology (1 of 14 cases), organizational factors (3 of 14 cases), or procedural factors (1 of 14 cases). Implementing an incident reporting system is quite demanding; the process should involve all of the people who work within

    The results of operation performed within the first six months of life upon seventy-seven resistant club feet are presented. The indications for and the rationale of early operation are discussed. Particular attention has been paid to the relationship between the age at operation and the outcome more than four years later; the results were greatly superior when operation was undertaken early. Two surgical techniques are compared, the postero-medial release proving better than a simple posterior release. The relationship between clinical and radiological assessment is discussed, and also the influence of the results reported upon future practice.

    The publicly available Japanese data on the use of slim holes in geothermal exploration and reservoir assessment are reviewed in this report. Slim holes have been used for (1) obtaining core for geological studies, (2) delineating the stratigraphic structure, (3) characterizing reservoir fluid state (pressure, temperature, etc.), and (4) defining the permeability structure for reservoir assessment. Examples of these uses of slim hole data are presented from the Hohi Geothermal Area and the Sumikawa Geothermal Field. Discharge data from slim holes and production wells from the Oguni Geothermal Field indicate that it may be possible to infer the discharge rate of production wells based on slim hole measurements.

    This article reports on a method to digitally survey and build virtual patterns for removable partial denture (RPD) frameworks using a new three-dimensional (3D) computer-aided design/computer-assisted manufacturing (CAD/CAM) software package developed specifically for RPD design. The procedure included obtaining 3D data from partially dentate casts, deciding on the path of insertion, and modeling the shape of the components of the frameworks digitally. The completed model data were stored as stereolithography (STL) files, which are commonly used in transferring CAD/CAM models to rapid prototyping technologies. Finally, metal RPD frameworks were fabricated using a selective laser melting technique.

    This study examined whether gentle Hatha yoga reduced fibromyalgia-related symptoms for a convenience sample of 10 participants ranging in age from 39 to 64 years who received yoga instruction 2 times per week for 8 weeks. Respondents completed the Fibromyalgia Impact Questionnaire 1 time per week and provided weekly journal reports regarding their health status. Pre- and post-intervention manual tender point evaluations were also conducted. Findings provide evidence of association between participating in gentle Hatha yoga classes and reduced fibromyalgia - related symptoms. Additional randomized controlled trials with larger sample sizes and greater empirical rigor are needed to more fully understand this relationship.

    Maternal support is an important factor in predicting outcomes following disclosure of child sexual abuse; however, definition of the construct has been unclear and existing measures of maternal support are utilized inconsistently and have limited psychometric data. The purpose of this study was to develop a reliable and valid mother-report measure for assessing maternal support following the disclosure of child sexual abuse. Data from 2 very similar samples of mother-child pairs seeking forensic evaluation following the discovery of child sexual abuse were combined, resulting in a final sample of 246. Exploratory factor analysis resulted in two reliable 7-item factors labeled "Emotional Support" and "Blame/Doubt," each of which had acceptable internal consistency. Analyses with a child-report measure of general maternal support the construct validity of the MSSQ. Concurrent validity analyses revealed unique relations with maternal ratings of child behavior problems and case characteristic data. The study resulted in the development of a brief, easily scored self-report measure of maternal support with reasonable preliminary psychometric properties that could easily be utilized in other studies of sexually abused children. Adoption of this promising measure in future research will reduce the lack of cross-study measurement comparability that has characterized the maternal support literature to date, increase the feasibility of expanding upon current literature on maternal support, and may produce important information leading to clinical and theoretical innovation.

    The accurate diagnosis of fetal malformations in utero can provide both heath care providers and parents a number of management options. Three-dimensional ultrasonography is a new technique of diagnosis which has several potential advantages to allow for evaluation of specific anomalies by permitting high-quality views of body surface. We report 4 cases of fetal chromosomal abnormalities including 2 cases of trisomy 21, 1 case of trisomy 13 and 1 case of 48, XXY/+18. All cases were proved to have abnormal chromosomes by amniocentesis or percutaneous umbilical cord blood sampling. After 3D reconstruction, we can identify specific facial abnormalities which can not be visualized by conventional two-dimensional ultrasound such as low set ear Mongolian's slant eyes, facial dysmorphism of trisomy 13 and trisomy 18. We also clearly visualized abnormalities of digits such as overlapping fingers, club hands and sandal gap. Three-dimensional reconstruction of the fetal body surface improves the antenatal diagnosis of chromosomal abnormalities characterized by a particular dysmorphism. Our report suggests that three-dimensional ultrasonography has the potential to provide novel informations on the fetal anatomy and be useful in visualization and identification of chromosomal abnormalities in utero.

    Lymphoedema of the extremities is a widespread pathological condition that mostly occurs as a complication of cancer resections, especially in women. Conventional therapy refers to conservative and physiotherapeutic approaches. Surgical strategies have been widely reported in the literature and are still challenging. Part of this literature focuses on the supra microsurgical lymphaticovenular anastomosis (LVA) technique. LVA is characterized by a high success rate, minimal invasivity and broad indications. Furthermore, this procedure can be performed under local anesthesia. From October 2011 through October 2014, 69 patients affected by lymphedema underwent LVA surgery in Siena University Hospital, Italy. Preoperative and postoperative evaluations were taken. Totally, 366 anastomosis have been performed. The average rate was 5.3 anastomosis per patient. All patients registered a decrease in the size of the affected side. The average volume reduction was 50%. Patients also showed a reduction of lymphangitis episodes and reduction of compression garments class. Moreover, a satisfaction index was evaluated. The majority of patients (72.5%) was extremely satisfied of the surgery. LVA has demonstrated to be an effective surgical strategy to treat lymphoedema, especially in secondary cases in early stages. Although LVA is widely discussed in the literature, the majority of works relates to Japanese authors and few reports exist outside Japan. This paper represents the very first retrospective analysis of the adoption of LVA technique in Italy and one of the few outside Japan.

    Paleozoic and Early Mesozoic radiolarians are newly recovered from chert and associated fine-grained clastic rocks in Thailand. This study clarifies the geologic age of these radiolarian rocks and their paleogeographic and geotectonic significance. Devonian, Early Carboniferous and Permian radiolarians were found in the "Fang Chert" which outcrops along the Chiang Mai-Fang Road, upper north Thailand, Early Carboniferous radiolarians were recovered from a sequence of tuffaceous shale and chert exposed in the Pak Chom area along the Mekong River, and well-preserved Late Devonian and Early Carboniferous radiolarians were also recovered from cherts exposed along the Pak Chom-Loei Road near Phu Laem, north of Loei, in northeast Thailand. These Devonian to Carboniferous radiolarian faunas are apparently identical with those reported from eastern and western Australia. Well-preserved Early Triassic conodonts and radiolarians were obtained from a limeston exposed near Patthalung, southern Thailand. Most of the radiolarian species of this fauna show close affinity with those reported from the Upper Paleozoic rocks, and are new species except for some spicule-type forms. Based on the above-mentioned newly obtained micropaleontological evidence, the geotectonic significance of these radiolarian rocks are briefly discussed in relation to the paleography of the Palaeo-Tethys Ocean, Sibumas and Indochina Terranes, and Australia during the Late Devonian to Middle Permian times.

    Areca nut (Areca catechu) is chewed by roughly 10% of the world population, including India, Taiwan and parts of China. Lower mean birth-weight and higher neonatal jaundice were reported in the babies of betel chewing pregnant women in 1982. Although areca nut chewing during pregnancy has been associated with lower birth weight and premature delivery, the mechanism of such complications is not entirely understood. A possible contributor, arecoline, a major alkaloid in the areca nut, has been reported to be cytotoxic and genotoxic. To determine the influence of arecoline on reproduction, we study the effects of arecoline on embryos during peri-implantation stages in mice. Mice consuming varying dosages of arecoline were checked for their ability to successfully produce viable embryos. In addition, trophoblast outgrowth from mice blastocysts was evaluated the survival status of the embryos. Our investigation revealed that arecoline decreased the number of implanted embryos in early pregnant mice. In addition, trophoblast outgrowth expansion of blastocysts was also inhibited by arecoline. These observations suggest that arecoline is toxic to mouse embryos as early as peri-implantation. Improved understanding of the effects of arecoline during embryogenesis may help to establish public health policies and to develop potential treatments for such patients.

    1997-04-01

    This report summarizes the efforts completed in identifying candidate fluorescence compounds and radioisotopes for a developing tagging system. The tagging system is being developed as a deterrent to nuclear smuggling, by providing a means of: (1) tracing materials and pilferers to the facility of origin for any recovered special nuclear materials, (2) inventory control of long-term stored items containing special nuclear materials, and (3) tracking materials transferred between facilities. The system uses three types of materials to cover a range of applications intended to prevent the pilfering of special nuclear materials. One material, fluorescent compounds which are invisible without ultraviolet or near-infrared detection systems, is marked on controlled items with a tracking pattern that corresponds to a specified item in a specified location in the data control system. The tagging system uses an invisible, fluorescent dusting powder to mark equipment and personnel who inappropriately handle the tagged material. The tagging system also uses unique combinations of radionuclides to identify the facility of origin for any special nuclear material. This report also summarizes the efforts completed in identifying hardware that will be used for the tagging system. This hardware includes the devices for applying the tagging materials, the commercially available fluorescence detection systems, and gamma ray detection systems assembled from existing, commercially available technologies.

    2014-01-01

    Although neuromyelitis optica (NMO) is classically recognized as an affectation of optic nerves and spinal cord, recent reports have shown brain atrophy and cognitive dysfunction in this condition. Importantly, emotion-related brain regions appear to be impaired in NMO. However, no studies of NMO' emotional processing have been published. The goal of the current study was to investigate facial emotion recognition in 10 patients with NMO and 10 healthy controls by controlling for relevant cognitive factors. Consistent with previous reports, NMO patients performed poorly across cognitive domains (divided attention, working memory, and information-processing speed). Our findings further evidence the relative inability of NMO patients to recognize negative emotions (disgust, anger, and fear), in comparison to controls, with these deficits not explained by other cognitive impairments. Results provide the first evidence that NMO may impair the ability to recognize negative emotions. These impairments appear to be related to possible damage in brain regions underling emotional networks, including the anterior cingulate cortex, amygdala, and medial prefrontal cortex. Findings increased both our understanding of NMO's cognitive impairment, and the neural networks underlying negative emotions.

    Our aim is to compare the immune response after colorectal surgery performed laparoscopically and via traditional technique. This response seems to be proportional to the level of the surgical trauma and presumably is directed to improve host defence. This is a prospective reported study based on patients' randomisation. Fourteen patients with colorectal diseases undergoing laparoscopic or open surgery were enrolled. After both laparoscopic and open colorectal surgery, we observed a significant increase of circulating C-Reactive Protein (CRP) levels. The count of lymphocytes subpopulations did not show significant differences after both procedures. IL-6 serum levels increased immediately after laparoscopic approach. IL-6 production was preserved only in the laparoscopic group, while its plasma levels were significantly higher in conventional group. Postoperative cell-mediated immunity was better preserved after laparoscopic than after conventional colorectal resection. Laparoscopy became a popular approach to treat surgically benign and malignant colorectal diseases and several authors reported a better immune response in patients performing laparoscopic surgery after comparing to conventional colorectal surgery. These findings may have important implications in performing a laparoscopic colorectal resection.

    Minimally invasive osteoid osteoma resection under computer tomography (CT) guidance has yielded good results and has become a viable alternative to open surgical procedures. Limited visualization of the actual drill position under CT guidance can frequently result in inadequate and malpositioned drilling, especially at lesions located in less accessible anatomic regions. With the conventional CT-guided drilling technique, sterility and general operative management poorly correlate with standard operating room conditions, and are at risk of intra- and postoperative complications. The new Iso-C(3D) imaging device provides intraoperative multiplanar reconstructions. Adequate image quality and implementation in navigation systems were described for numerous indications. On the basis of multiplanar reconstructions, minimally invasive navigated techniques under three-dimensional surgical tool control become possible, which is not the case under fluoroscopic or CT-based navigation. We report on our first three cases of navigated Iso-C(3D) osteoid osteoma resection. A minimally invasive resection of the nidus was possible under permanent multiplanar image control. No complications were encountered and all patients reported successful outcomes. Minimally invasive-based navigation offered an effective and reproducible surgical approach. Dependence on CT imaging for proper positioning and complications associated with use away from the operating room environment can be avoided.

    The Apex and Paymaster mines in the Tutsagubet mining district, 25 miles southwest of St. George, Utah, are at an elevation of about 5,000 feet in the Beaver Dam Mountains. The ore was deposited in a steeply dipping fault zone which cuts a thick series of gently dipping limestones of Pennsylvanian age with minor interbedded shales and sandstones. The ore now consists primarily of copper oxides, but is reported to contain small quantities of lead and sine oxides. Complete oxidation extends to the 1,400 level of the Apex mine, the deepest level in this mine. Lead oxides are reported to have been more plentiful in the workings near surface, but the stoped area is now caved to the 1,330 level. The ore bodies probably formed largely as a filling in the fault fissure, and in crushed zones along the fault, with only minor replacement extending for short distances along the bedding. The sulfides oxidized essentially in place and migration of the oxidized copper ores is believed to be limited to a few feet. Additional exploration below the known ore shoots in the Apex and Paymaster mines and along the fissure between the two mines may disclose new ore bodies.

    Young people with special educational needs are also users of new media. The aim of the study was to determine whether pupils with visual impairment spend more time on Internet use than pupils without visual impairment and whether youngsters from the study group are engaged in behaviors which could increase risk of problematic Internet use. The study is based on a total of 191 pupils: a study group of 66 partially-sighted pupils and a control group comprised 125 pupils who do not have visual impairment. A self-report questionnaire was constructed for the needs of this study. Pupils with visual impairment spent significantly less time on Internet use than their peers from the reference groups. Twice as many pupils from the study group as controls reported no symptoms suggesting potentially problematic Internet use. In addition, the study group more frequently used online social networking services and e-mails or used the Internet for assignments. Little difference exists between students with visual impairment and those without with regard to Internet use. Copyright © 2016 Elsevier Inc. All rights reserved.

    What do patients expect from a treatment? A patient-centred approach to treatment is becoming necessary given the choices for invasive treatments for Parkinson's disease. Patient's perceptions of severity and expectations from complex therapies have not been studied. We describe the rationale and concept of developing a Patient-Reported Outcome (PRO) tool to assess perceptions of symptom severity and expectations of therapy. We report preliminary findings from use of the tool, association with clinical factors, and illustrate the potential use in individual patients awaiting therapy. Patient symptoms were grouped into four domains, with 8 motor, 7 non-motor, 7 psychological and 4 social questions. For each question, symptom severity was rated on a Likert scale scoring from 0 (no problem) to 7 (perceived as a severe problem). Similarly, the expectation for each symptom to change after therapy was rated on a Likert scale: score -3 (expected to be very much worse) to + 3 (expected to be very much improved). 22 consecutive patients, routinely planned to receive one of Deep Brain Stimulation/Intrajejunal Levodopa Infusion/Apomorphine Infusion therapies, were recruited: 13 male, mean (+/-sd) age: 65.6 (+/-9.5) years, mean (+/-sd) disease duration: 14.3 (+/-5.7) years. Subjective severity scores are reported as mean (+/-sd) / maximum possible score: (i) motor 23.5 (+/-7.5) / 56, (ii) non-motor 15.5 (+/-5.6) / 49, (iii) cognitive - psychological 12.4 (+/-5.8) / 49, (iv) social 9.3 (+/-4.1) / 28. Expectation of change (improvement) scores are reported as mean (+/-sd) / maximum possible score of: (i) motor 14.0 (+/-5.6) / 24, (ii) non-motor 8.5 (+/-4.1) / 21, (iii) cognitive - psychological 7.4 (+/-4.4)/ 21, and (iv) social 5.5 (+/-2.8) / 12. For each domain, Spearman correlation coefficient showed significant associations between severity and expectation within-domain. This tool (PRO-APD) provides a description of perceived problem severity and expectation of treatments
