    The case of a female 68 years old patient is described. Here, a chronic lead intoxication was diagnosed after a two year old medical history with increasing attacks of colic-like abdominal pain often described as life-threatening. After repeated hospitalizations and intensive search for the cause of the symptoms, porphyria and anemia was found to be a sign of a chronic lead poisoning. The blood lead concentrations were always about a level of 600 {mu}g/L. The source of exposure could not be found by now. Neither home inspection nor environmental investigations have shown a recent source of lead intake by the patient. However, a possible occupational source of lead exposure at a blast furnace was established by anamnesis for 1952 to 1962. Thus, osteoporosis induced lead mobilisation was suspected. Noticeable are the results of the six abdominal survey radiographies taken during hospitalization within one year; three radiographies were taken following clinical admission and three before discharge of the patient. In comparison, the course shows a chronic relapsing alimentary supply from metallic particles of unknown genesis. The patient was treated with the sodium salt of 2,3-dimercapto-1-propansulfonic acid (DMPS, Dimaval{sup TM}). She was free of complain afterwards. Following therapy, the blood lead concentrations fell under a level of 400 {mu}m/L, but after several weeks the lead level raised up to the original level of 600 {mu}g/L. (orig.)

    Full Text Available Die Akkumulation von Knorpel- und Knochenschäden, wie sie für chronisch-destruktive Arthritisformen typisch ist, kann durch frühzeitige Intervention mit wirksamen Medikamenten verzögert oder verhindert werden. Voraussetzung ist die rechtzeitige Übernahme der Betreuung gefährdeter Patienten durch einen in der speziellen rheumatologischen Diagnostik und Therapie bewanderten Arzt. Dieser muß das gesamte Repertoire der Arthritistherapie (Medikamente, ergotherapeutische und physiotherapeutische Maßnahmen, Patientenaufklärung etc. entsprechend dem „State of the Art“ beherrschen. In den letzten Jahren erfolgte in vielen Ländern die Etablierung von Spezialeinrichtungen für Patienten mit früher Arthritis. Die an diesen Patienten gewonnenen Erkenntnisse deuten darauf hin, daß die „kritische Periode“, innerhalb derer eine chronische Arthritis möglicherweise reversibel ist, bei 6 bis 12 Wochen liegt.

  4. Success rate of overfilled root canal treatment

    Traditionally, poor obturation has been considered the primary cause of root canal treatment failures The purpose of this study was to assess the success rate of overfilled root canal treatment cases in order to decide whether a definitive restoration can be placed immediately following treatment in an overfilled case or whether the patient needs to be kept on a follow up prior to the placement of a definitive restoration. Methods: A total of 1242 patients periapical radiographs (1748 teeth) were assessed, out of which 397 teeth (in 285 patients) were found to be overfilled. Out of these 285 patients, 111 (128 cases) agreed to participate in this cross sectional study and were recalled for clinical and radiographic examination. Success was evaluated clinically by absence of symptoms (pain, swelling, tenderness to percussion and sinus tract) and radiograhically by the decrease in size of periapical lesion or no change in size. Increase in size of periapical lesion was deemed to be a failure. Results: Our findings revealed that despite overfill, the treatment was successful in 115 cases and failure was noted in 13 cases showing an overall success rate of 89.8% and failure rate of 10.2%. Out of 13 cases of failure, all 13 showed an increase in periapical lesion size, out of which 10 were accompanied with pain. Conclusion: Based on the results obtained in our study, we have determined that there is no need to delay placement of a permanent restoration on overfilled teeth (ruling out the presence of other procedural errors) nor is there any need to pursue any further surgical or non-surgical endodontic treatment. However we would suggest that patients should be kept on follow-up after placement of permanent restoration. (author)

    high-resolution coils, the investigation of the ankle joint still offers a wide spectrum of innovation for the next years, which is particularly enforced by the increasing demand for specific diagnosis of chronic diseases in orthopedic medicine. (orig.) [Deutsch] Die Aetiologie chronischer Krankheitsbilder am Sprunggelenk ist vielfaeltig. Chronisch entzuendliche Veraenderungen, wie sie im Rahmen einer chronisch juvenilen Arthritis, des M. Reiter, der Psoriasis oder chronischer Monoarthritiden, wie der chronischen Gicht zu beobachten sind, haben nicht selten ihre Manifestation am Sprunggelenk. Seltenere entzuendlich chronische Affektionen hingegen koennen jedoch auch bei enteropathischen Arthritiden, granulomatoesen Erkrankungen, wie der Tuberkulose oder Sarkoidose, beobachtet werden. Auch chronisch verlaufende Pilzaffektionen koennen zu atypischen Bildern fuehren. Chronisch degenerative Erkrankungen entstehen am Sprunggelenk fast ausschliesslich sekundaer. Praedisponierend sind hier angeborene oder erworbene Fehlhaltungen sowie chronische Veraenderungen auf Basis abgelaufener oder repetitiver Traumen. Der neuropathische Formenkreis stellt eine weitere Causa chronischer Veraenderungen dar, mit im fortgeschrittenem Stadium massiven Gelenks- und ossaeren Veraenderungen. Chronische Veraenderungen sind auch bei der Haemophilie im Rahmen des Blutergelenkes zu erwarten. Als chronisch tumoroese Veraenderungen koennen die pigmentierte villonodulaere Synovitis (PVNS) und die Gelenkschondromatose betrachtet werden, mit teils ossaeren und teils charakteristischen Kapsel und Weichteilveraenderungen. Die modernen Gelenkdiagnostik umfasst zudem auch chronische Veraenderungen an den Sehnen und Baendern. Besondere diagnostische Herausforderungen stellen letztendlich Syndrome dar, die klinisch zwar beobachtet, jedoch erst durch moderne Bildgebung in den letzten Jahren zunehmend spezifiert werden konnten. Diese umfassen zum Beispiel das `Os-trigonum-Syndrom`, das `anterolaterale

    Compared with spinal epidural hematomas, spinal subdural hematomas are rare; chronic forms are even more uncommon. These hematomas are associated not only with lumbar puncture and spinal trauma, but also with coagulopathies, vascular malformations and tumors. Compression of the spinal cord and the cauda equina means that the patients develop increasing back or radicular pain, followed by paraparesis and bladder and bowel paralysis, so that in most cases surgical decompression is carried out. On magnetic resonance imaging these hematomas present as thoracic or lumbar subdural masses, their signal intensity varying with the age of the hematoma. We report the clinical course and the findings revealed by imaging that led to the diagnosis in three cases of chronic spinal subdural hematoma. (orig.) [German] Spinale subdurale Haematome sind im Vergleich zu epiduralen Haematomen selten, chronische Verlaufsformen noch seltener. Ursaechlich sind neben Lumbalpunktionen und traumatischen Verletzungen auch Blutgerinnungsstoerungen, Gefaessmalformationen und Tumoren. Aufgrund der Kompression von Myelon und Cauda equina kommt es zu zunehmenden Ruecken- oder radikulaeren Schmerzen mit anschliessender Paraparese sowie einer Darm- und Blasenstoerung, weshalb in den meisten Faellen eine operative Entlastung durchgefuehrt wird. Magnetresonanztomographisch stellen sich die Haematome meist als thorakale bzw. lumbale subdurale Raumforderungen dar, die Signalintensitaet variiert mit dem Blutungsalter. Wir berichten ueber den klinischen Verlauf und die bildgebende Diagnostik von 3 Patienten mit spinalen chronischen subduralen Haematomen. (orig.)

    The diagnosis of chronic osteomyelitis is made on the basis of clinical, radiologic and histologic findings. The role of imaging in patients with known chronic osteomyelitis is to detect and to delineate areas of active infection. To correctly interpret the imaging findings, it is essential to take both the individual clinical findings and previous imaging studies into account. Reliable signs of active infection are bone marrow abscess, sequestra and sinus tract formation. Only the combined evaluation of bony changes together with alterations of the adjacent soft tissues provides good diagnostic accuracy. Projection radiography gives an overview of the condition of the bone, which provides the basis for follow-up and the selection of further imaging modalities. Computed tomography can be used to evaluate even discrete or complex bony alterations and to guide percutaneous biopsy or drainage. Magnetic resonance imaging achieves the best diagnostic sensitivity and specificity and provides superior contrast as well as anatomical resolution in both bone marrow and soft tissues. In this paper the features and clinical relevance of imaging in primary chronic osteomyelitis, posttraumatic osteomyelitis, tuberculous spondylitis and osteomyelitis of the diabetic foot are reviewed, with particular respect to MRI. (orig.) [German] Die Diagnose der chronischen Osteomyelitis wird durch Klinik, Bildgebung und Histologie gestellt. Bei bekannter chronischer Osteomyelitis soll die Bildgebung einen floriden Prozess und die betroffenen Kompartimente herausarbeiten. Die Klinik des Patienten, seine individuelle Krankheitskonstellation und die Verlaufsbeobachtung sind essentiell fuer die Befundinterpretation. Erst die kombinierte Beurteilung der Veraenderungen am Knochen selbst sowie die der umgebenden Weichteile fuehrt zu einer validen Aussage. Sichere Zeichen einer floriden Osteomyelitis sind lediglich (Knochenmarks)abzess, Sequester und Fistelgang. Die Projektionsradiographie gibt

    No data are available regarding the success of DNA Short Tandem Repeat (STR) profiling from degraded skeletal remains in Guatemala. Therefore, DNA profiling success rates relating to 2595 skeletons from eleven cases at the Forensic Anthropology Foundation of Guatemala (FAFG) are presented. The typical postmortem interval was 30 years. DNA was extracted from bone powder and amplified using Identifiler and Minifler. DNA profiling success rates differed between cases, ranging from 50.8% to 7.0%, the overall success rate for samples was 36.3%. The best DNA profiling success rates were obtained from femur (36.2%) and tooth (33.7%) samples. DNA profiles were significantly better from lower body bones than upper body bones (p = <0.0001). Bone samples from males gave significantly better profiles than samples from females (p = <0.0001). These results are believed to be related to bone density. The findings are important for designing forensic DNA sampling strategies in future victim recovery investigations. © 2016 American Academy of Forensic Sciences.

    We evaluated the success rate of direct vision internal urethrotomy as a treatment for simple male urethral strictures. A retrospective chart review was performed on 136 patients who underwent urethrotomy from January 1994 through March 2009. The Kaplan-Meier method was used to analyze stricture-free probability after the first, second, third, fourth and fifth urethrotomy. Patients with complex strictures (36) were excluded from the study for reasons including previous urethroplasty, neophallus or previous radiation, and 24 patients were lost to followup. Data were available for 76 patients. The stricture-free rate after the first urethrotomy was 8% with a median time to recurrence of 7 months. For the second urethrotomy stricture-free rate was 6% with a median time to recurrence of 9 months. For the third urethrotomy stricture-free rate was 9% with a median time to recurrence of 3 months. For procedures 4 and 5 stricture-free rate was 0% with a median time to recurrence of 20 and 8 months, respectively. Urethrotomy is a popular treatment for male urethral strictures. However, the performance characteristics are poor. Success rates were no higher than 9% in this series for first or subsequent urethrotomy during the observation period. Most of the patients in this series will be expected to experience failure with longer followup and the expected long-term success rate from any (1 through 5) urethrotomy approach is 0%. Urethrotomy should be considered a temporizing measure until definitive curative reconstruction can be planned. 2010 American Urological Association Education and Research, Inc.

    2016-04-01

    While research has examined the likelihood that drugs progress across phases of clinical trials, no research to date has examined the types of product development strategies that are the most likely to be successful in clinical trials. This research seeks to identify the strategies that are most likely to reach the market-those generated using a novel product development strategy or strategies that combine a company's expertise with both drugs and indications, which we call combined experience strategies. We evaluate the success of product development strategies in the drug development process for a sample of 2562 clinical trials completed by 406 US pharmaceutical companies. To identify product development strategies, we coded each clinical trial according to whether it consisted of an indication or a drug that was new to the firm. Accordingly, a clinical trial that consists of both an indication and a drug that were both new to the firm represents a novel product development strategy; indication experience is a product development strategy that consists of an indication that a firm had tested previously in a clinical trial, but with a drug that was new to the firm; drug experience is a product development strategy that consists of a drug that the firm had prior experience testing in clinical trials, but with an indication that was new to the firm; combined experience consists of both a drug and an indication that the firm had experience testing in clinical trials. Success rates for product development strategies across clinical phases were calculated for the clinical trials in our sample. Combined experience strategies had the highest success rate. More than three and a half percent (0·036) of the trials that combined experience with drugs and indications eventually reached the market. The next most successful strategy is drug experience (0·025) with novel strategies trailing closely (0·024). Indication experience strategies are the least successful (0·008

    Although reoperation rates for upper lid retraction surgery for thyroid eye disease (TED) typically range between 8% and 23%, there is little literature describing the outcomes of these second operations. In this retrospective observational cohort study, all patients that underwent surgery for upper eyelid retraction over a 14-year period at a single institution were included. Cases were included if a second eyelid retraction surgery was performed during the study period. Success of surgery was defined as a marginal reflex distance (MRD1) of 2.5 to 4.5 mm in each eye and less than 1 mm difference in MRD1 between the eyes. Overcorrection and undercorrection were defined as above and below these bounds, respectively. 72 eyes in 49 patients were included in the study. The mean age was 56.6 (±11.5) years. By definition, all patients had at least 1 lid lengthening surgery for upper eyelid retraction, and at least 1 subsequent surgery. For this second surgery, 61 eyes (85%) underwent retraction surgery and 11 eyes (15%) underwent ptosis surgery. After this second operation, 31% were undercorrected and 33% were overcorrected. A third surgery was performed in 19 eyes (25%), 12 had surgery for residual retraction and 7 for ptosis. After the third operation 10% of eyes were under corrected and 11% were over corrected. Four patients underwent a fourth surgery: one for retraction and three for ptosis. Success was noted in 35% after the second surgery and 44% after the third. Surgical success in eyelid retraction surgery increases from a second to a third consecutive surgery, and residual asymmetry was roughly equally distributed between over- and undercorrection.

    "Smart growth" is to pursue the best integrated perform+-ance of the Economically prosperous, socially Equitable, and Environmentally Sustainable(3E). Firstly, we establish the smart growth evaluation system(SGI) and the sustainable development evaluation system(SDI). Based on the ten principles and the definition of three E's of sustainability. B y using the Z-score method and the principal component analysis method, we evaluate and quantify indexes synthetically. Then we define the success of smart growth as the ratio of the SDI to the SGI composite score growth rate (SSG). After that we select two cities — Canberra and Durres as the objects of our model in view of the model. Based on the development plans and key data of these two cities, we can figure out the success of smart growth. And according to our model, we adjust some of the growth indicators for both cities. Then observe the results before and after adjustment, and finally verify the accuracy of the model.

    In several studies, different risk factors other than antibiotic resistance have been documented with Helicobacter pylori eradication failure. We aimed in this study to investigate the relationship of gastric density of H. pylori, the occurrence/degree of gastric atrophy, and intestinal metaplasia (IM) with success rate of H. pylori eradication. Two hundred consecutive treatment naive patients who received bismuth containing standart quadruple treatment due to H. pylori infection documented by histopathological examination of two antral or two corpal biopsies entered this retrospective study. The updated Sydney system was used to grade the activity of gastritis, density of H. pylori colonization, atrophy, and IM. Stages III and IV of operative link for gastritis assessment (OLGA) or the operative link on gastric intestinal metaplasia assessment (OLGIM) stages was considered as severe gastritis. H. pylori eradication was determined via stool H. pylori antigen test performed 4 weeks after the end of therapy. The presence of gastric atrophy and IM was significantly higher in patients with eradication failure (p = 0.001 and 0.01, respectively). Severe gastritis (OLGA III-IV and OLGIM III-IV) rates were higher in eradication failure group. A multiple linear regression analysis showed that OLGA and OLGIM stages were to be independent risk factors for eradication failure (p = 0.03 and 0.01, respectively). Our results suggested that histopathologically severe gastritis may cause H. pylori eradication failure. In addition, we found that H. pylori density was not a risk factor for treatment failure in patients who receive quadruple treatment.

    To conduct a systematic review to assess recruitment rates in workplace physical activity (PA) intervention studies and describe characteristics of studies with high recruitment rates. Data Source. Electronic and manual searches were conducted. Workplace PA intervention studies that reported the number of employees invited to participate and the number who responded were included. Studies with recruitment rates of ≥70% were categorized as high with the remaining studies (recruitment rate. Seventy-six percent of studies failed to report recruitment rates (n = 30 included for review). Studies with high recruitment rates (n = 8) tended to have longer study duration (mean 1.6 years) and target smaller cohorts of employees (mean n = 199) than comparison studies (3.9 months; n = 1241). For recruitment strategies and intervention components of high studies, involvement of employees was driven by the organization, with PA interventions provided as part of the working day in paid time. These findings suggest a potential to improve recruitment through targeting small cohorts of employees, incorporating PA as a long-term strategy, facilitating organizationally driven employee involvement, and providing PA interventions during paid time.

    Full Text Available In this study, we aimed to determine factors affecting the success rate of percutaneous nephrolithotomy (PNL in children. The series consisted of 41 consecutive children operated on by the same surgical team for renal calculi with PNL between June 2002 and May 2015 in our institution. A single calyx or pelvic stone was described as simple, while calculi located in more than one location (calyx and pelvis or more than one calices or staghorn stones were described as complex. The procedure was deemed successful if the patient was completely stone-free (SF or had residual fragments <4 mm. Thirty-four patients were found to be SF or had residual fragments <4 mm on the postoperative first day, thus the success rate was 82.9%. In complex stones, the success rate was significantly lower (45.5% than simple stones (96.7% (p < 0.001. The grade of hydronephrosis (Grade 0–1 vs. Grade 2–3 also had a negative impact on the success, with rates of 92.6% vs. 64.3%, respectively (p = 0.022. Previous urological procedure history on the same side yielded a success rate of 58.3%, whereas the success rate in the primary patients was 93.1% (p < 0.001. The localization of the stone (complex vs. simple, degree of hydronephrosis, and history of previous urological procedures were found to be the factors that affected the success of the paediatric PNL.

    Rheumatoid arthritis is a chronic, multisystemic disease. The characteristic feature is persistent inflammatory synovitis. The knee joint is commonly involved with synovial hypertrophy, chronic effusion, and frequently ligamentous laxity. Pain and swelling behind the knee may be caused by extension of inflamed synovium into the popliteal space (Baker`s cyst). Plain radiographs of the knee joint remain the basic radiological procedure, although early in the disease they might not provide significant changes. Sonography sufficiently reveals synovial fluid and Baker cysts, but cannot be recommended for evaluation of synovial proliferations or pannus formation. Computer tomography has only limited indications and may be used for the evaluation of subtle erosive lesions or the quantitation of osteoporotic changes. Magnetic resonance imaging has shown excellent visualization of cartilage, fluid, synovium and soft tissues and is the method of choice for the demonstration of early affection and the evaluation of panus activity and therapy control. With daministration of contrast agents (gadolinium), dynamic studies may demonstrate inflammatory activity. Modern MR sequences, such as T1 SE `fat sat` or magnetization transfer, further improve the discrimination of cartilage, pannus and synovial fluid. (orig.) [Deutsch] Die chronische Polyarthritis (CP) ist eine multisystematische Erkrankung und wird charakteristischerweise von einer persistierenden inflammatorischen Synovitis begleitet. Das Kniegelenk ist das haeufigste einzeln betroffene Gelenk, seine Affektion manifestiert sich zumeist mit synovialer Hypertrophie, chronischen Erguessen und oftmals auch Bandinstabilitaet. Schmerzen sowie Schwellungen in den dorsalen Weichteilen sind oft durch Vordringen inflammatorischer Synovia oder Ergussansammlungen bedingt (Baker-Zyste). Das konventionelle Roentgenbild bildet zwar einen Grundpfeiler in der CP-Diagnostik, zeigt jedoch oft erst bei fortgeschrittenem Krankheitsverlauf

    Purpose: to evaluate the technical and clinical success rates of percutaneous stent revascularization in the treatment of chronic mesenteric ischemia (CMI). Patients and methods: 17 patients (12 female) with typical symptoms of CMI were treated by percutaneous stent placement for stenoses of the splanchnic arteries (celiac trunk; superior mesenteric artery, SMA; inferior mesenteric artery, IMA). The primary and secondary technical success, primary and secondary clinical success, and the long-term clinical outcome were determined. Results: a total of 24 stents were implanted in 21 splanchnic arteries (12 stents in the celiac trunk, 11 in the SMA and 1 in the IMA). The primary technical success rate was 91% (19/21 arteries), the secondary technical success rate was 95% (21/22 arteries). Clinical follow-up was available for 16 patients. The primary clinical success rate was 81% (13/16 patients). Following two secondary interventions, the secondary clinical success rate was 94% (15/16 patients). Long-term clinical success was achieved in 15 of 16 patients (94%) with a mean follow-up of 26 months. One patient died within 30 days of the intervention and two patients demonstrated major complications (1 dissection, 1 stent dislocation). None of the patients required surgical revascularization and none of the patients died due to recurrent mesenteric ischemia. (orig.)

    There is a comprehensive literature on the academic outcomes (attrition and success) of students in traditional/baccalaureate nursing programs, but much less is known about the academic outcomes of students in accelerated nursing programs. The aim of this systematic review is to report on the attrition and success rates (either internal examination or NCLEX-RN) of accelerated students, compared to traditional students. For the systematic review, the databases (Pubmed, Cinahl and PsychINFO) and Google Scholar were searched using the search terms 'accelerated' or 'accreditation for prior learning', 'fast-track' or 'top up' and 'nursing' with 'attrition' or 'retention' or 'withdrawal' or 'success' from 1994 to January 2016. All relevant articles were included, regardless of quality. The findings of 19 studies of attrition rates and/or success rates for accelerated students are reported. For international accelerated students, there were only three studies, which are heterogeneous, and have major limitations. One of three studies has lower attrition rates, and one has shown higher success rates, than traditional students. In contrast, another study has shown high attrition and low success for international accelerated students. For graduate accelerated students, most of the studies are high quality, and showed that they have rates similar or better than traditional students. Thus, five of six studies have shown similar or lower attrition rates. Four of these studies with graduate accelerated students and an additional seven studies of success rates only, have shown similar or better success rates, than traditional students. There are only three studies of non-university graduate accelerated students, and these had weaknesses, but were consistent in reporting higher attrition rates than traditional students. The paucity and weakness of information available makes it unclear as to the attrition and/or success of international accelerated students in nursing programs. The

    Entanglement plays a crucial role in the efficacy of quantum algorithms. Whereas the role of entanglement is quite obvious and conspicuous in teleportation and superdense coding, it is not so distinct in other situations such as in search algorithm. The starting state in Grover's search algorithm is supposedly a uniform superposition state (not entangled) with a success probability around unity. An operational entanglement measure has been defined and investigated analytically for two qubit states [O. Biham, M.A. Neilsen, T. Osborne, Phys. Rev. A 65 (2002) 062312, Y. Shimoni, D. Shapira, O. Biham, Phys. Rev. A 69 (2004) 062303] seeking a relationship with the success rate of search algorithm. This Letter examines the success rate of search algorithm for various four-qubit states. Analytic expressions for the same have been worked out which can provide the success rate and entanglement measure for certain kinds of four qubit input states

    Stereotactic radiosurgery is generally accepted as one of the best treatment options for vestibular schwannomas. We question whether growth control is an accurate measure of success in vestibular schwannoma treatment. We aim to clarify the success rate of stereotactic radiosurgery and adjust the reported results to the benign natural history of untreated tumors. All articles were taken from a PubMed search of the English literature from the years 2000-2011. Inclusion criteria were articles containing the number of patients treated, radiation technique, average tumor size, follow-up time, and percentage of tumors growing during follow-up. Data were extracted from 19 articles. Success rates were adjusted using published data that 17% to 30% of vestibular schwannomas grow. The average reported success rate for stereotactic radiosurgery across all articles was 95.5%. When considering 17% or 30% natural growth without intervention, the adjusted success rates became 78.2% and 86.9% respectively. These rates were obtained by applying the natural history growth percentages to any tumors not reported to be growing before radiosurgical intervention. Success in the treatment of vestibular schwannomas with stereotactic radiosurgery is often defined as lack of further growth. Recent data on the natural growth history of vestibular schwannomas raise the question of whether this is the best definition of success. We have identified a lack of continuity regarding the reporting of success and emphasize the importance of the clarification of the success of radiosurgery to make informed decisions regarding the best treatment options for vestibular schwannoma.

    Background Using local anesthetic is common to control the pain through blocking the nerve reversibly in dental procedures. Gow-Gates (GG) technique has a high success rate but less common. This study aimed to compare the onset time and success rate in GG and standard technique of inferior alveolar nerve block (IANB). Material and Methods This descriptive, single blind study was consisted of 136 patients (59 males and 77 females) who were randomly received GG or IANB for extraction of mandibular molar teeth. Comparisons between the successes of two anesthetic injection techniques were analyzed with Chi-square test. Incidence of pulpal anesthesia and soft tissue anesthesia were analyzed with Kaplan-Meier method. Mean onset times of pulpal anesthesia, soft tissue and lip numbness were analyzed with Log-Rank test. Comparisons were considered significant at P≤0.05 by using SPSS software ver.15. Results The incidence of pulpal anesthesia in the IANB group (canine 49.3%, premolar 60.3%) were not significantly different from the GG group (canine 41.3%, premolar 74.6%) (P=0.200 and P=0.723). The success rate in the IANB group (80.82%) was not significantly different from the GG group (92.02%) (P=0.123). Furthermore, onset time of lip and buccal soft tissue numbness in GG group (3.25, 4.96 minutes) was quite similar to IANB group (3.22, 4.89 minutes) (all Pvalues >0.05). Conclusions Although this study demonstrated higher clinical success rate for GG than IANB technique, no significant differences in success rates and onset time were observed between two techniques.

    2015-12-01

    Background: The Essure ® (Bayer HealthCare Pharmaceuticals, Leverkusen, Germany) female sterilization procedure entails using a hysteroscope to guide a microinsert into the Fallopian tube openings. Failed placement can lead to patient dissatisfaction, repeat procedures, unintended or ectopic pregnancy, perforation of internal organs, or need for subsequent medical interventions. Additional interventions increase women's health risks, and costs for patients and the health care industry. Demonstrated successful placement rates are 63%-100%. To date, there have not been any systematic analyses of variables associated with placement rates. Objectives: The aims of this review were: (1) to estimate the average rate of successful bilateral Essure microinsert placement on first attempt; and (2) to identify variables associated with successful placement. Materials and Methods: A meta-analysis was conducted on 64 published studies and 19 variables. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, all published studies between November 2001 and February 2015 were reviewed. The studies were taken from from PubMed and Google Scholar, and by using the the "snowball" method that reported variables associated with successful bilateral Essure placement rates. Results: The weighted average rate of successful bilateral microinsert placement on first attempt was 92% (0.92 [95% confidence interval: 0.904-0.931]). Variables associated with successful placements were: (1) newer device models; (2) higher body mass index; and (3) a higher percent of patients who received local anesthesia. Conclusions: The data gathered for this review indicate that the highest bilateral success rates may be obtained by utilizing the newest Essure device model with local anesthesia in heavier patients. More standardized data reporting in published Essure studies is recommended. (J GYNECOL SURG 31:308).

    The objective of the present study was to investigate success rates and associated factors affecting temporary anchorage device (TAD) failure in different biomechanical applications. A total of 180 TADs were used as a part of 82 patients' treatment plan (24 males and 58 females); their mean age was 21.41 years. Three types of TADs were used: 50 (3M ESPE, Neuss, Germany), 56 (Bone screw; Jeil Medical, Seoul, Korea), and 74 (Morelli, Sorocaba, Brazil). Eight maxillary and four mandibular sites were selected for insertion. Three different lengths (6, 8, and 10 mm) and three different diameters (1.5, 1.6, and 1.8 mm) were used. The force levels were set at 50, 100, 150, 200, and 250 g. Patient-, implant-, and operator-dependent factors were evaluated throughout the 266 days of function. Qualitative variables were described by proportions and percentages and analyzed using χ 2 test. The overall success rate was 82.2%. The higher age group showed a significantly higher success rate. Oral hygiene showed a statistically-significant (P ˂ .05) difference between both success and failure groups. All other patient-related factors showed no significant differences. Regarding force levels used, the highest success rate was in 250 g and the lowest was in 100 g. There were no significant differences between both groups regarding other implant- and operator-related factors. Temporary anchorage devices have a good success rate and are beneficial to be integrated in orthodontic treatment planning. Patient age, oral hygiene, and force level are the most significant factors affecting TAD success. © 2018 John Wiley & Sons Australia, Ltd.

    Full Text Available Background: Trabeculectomy is a surgical therapy for glaucoma to preserve visual function by lowering intraocular pressure (IOP. In some studies, the success of trabeculectomy in lowering IOP is greater than medication. Success is defined by IOP <21 mmHg, with or without glaucoma medication. Primary glaucoma based on the mechanism of aquous humor outflow is divided into primary open-angle glaucoma (POAG and primary angle-closure glaucoma (PACG. This study aimed to know the success rate of trabeculectomy in POAG and PACG. Methods: This study was a descriptive study conducted at Cicendo Eye Hospital using medical record of POAG and PACG patients who underwent trabeculectomy surgery on January–December 2013 with minimal one month follow-up. Data collection was conducted during September 2014. Data processed in this study were 100 eyes from 76 patients with diagnosis POAG and PACG. Results: The success rate for trabeculectomy in POAG was 79% and PACG was 86%, failure (IOP ≥ 21 mmHg 21% in POAG, and 14% in PACG for period 2013 at Cicendo Eye Hospital. Conclusions: The success rate of trabeculectomy at Cicendo Eye Hospital is good in one month, with or without glaucoma medication after surgery.

    2018-01-01

    The primary aims of this study were to test whether perceived dating success would differ between offline and online zero-acquaintance dating contexts and to investigate the role that self-esteem might play in these evaluations. Participants were presented with the same photos of targets in either an offline or online dating scenario and rated their chances of dating success along with their perceptions of how attractive they thought the target would consider them. Higher self-esteem individuals believed they would be rated as more attractive. There was an overall perception that, irrespective of self-esteem level, meeting online would lead to better chances of dating success. These findings are considered in relation to an increased ability to more precisely manage impressions and develop an image of the self which would be evaluated more positively online.

    The R&D productivity of pharmaceutical firms has become an increasingly significant concern of industry, regulators, and policymakers. To address an important aspect of R&D performance, public and private data sources were used to estimate clinical phase transition and clinical approval probabilities for the pipelines of the 50 largest pharmaceutical firms (by sales) by 3 firms size groups (top 10 firms, top 11-20 firms, and top 21-50 firms). For self-originated compounds, the clinical approval success rates were 14.3%, 16.4%, and 18.4% for top 10 firms, top 11-20 firms, and top 21-50 firms, respectively. The results showing higher success rates for smaller firms were largely driven by outcomes for the small-molecule drugs. Adjustments for the relatively small differences in therapeutic class distributions across the firm size groups showed that the success rate for small-molecule self-originated drugs was 6% below average for top 10 firms and 17% above average for top 21-50 firms. Although success rates for small firms were higher, this advantage was offset to some degree by lower returns on approved drugs, suggesting different strategic objectives with regard to risk and reward by firm size.

    To determine intrapartum and perinatal outcomes following successful external cephalic version for breech presentation at term. This was a retrospective cohort study of outcomes following successful external cephalic version in 411 women at an Australian tertiary maternity unit between November 2008 and March 2015. The study cohort was compared with a control group of 1236 women with cephalic presentation who underwent spontaneous labor. Intrapartum intervention rates and adverse neonatal outcomes were compared between both groups. The success rate of external cephalic version (ECV) was 66.4%. The spontaneous vaginal delivery rate in the study cohort was 59.4% (224/411) vs 72.8% (900/1236) in the control cohort (P<0.001). Intrapartum intervention rates (emergency cesarean section (CS) and instrumental delivery) were higher in the ECV group (38% vs 27.2%, P<0.001). Rates of emergency CS for non-reassuring fetal status (9.5%, 39/411 vs 4.4%, 54/1236, P⩽0.001) and failure to progress (13.4%, 55/411 vs 4.1%, 51/1236, P<0.001) were higher in the study cohort. Neonatal outcomes were worse in the study cohort-Apgar score <7 at 5 min (2.2%, 9/411 vs 0.6%, 8/1236, P<0.001) and abnormal cord gases (8.5%, 35/411 vs 0.2%, 3/1236, P<0.001). Rates for resuscitation at birth and admission to the neonatal intensive care unit were higher in the study cohort (6.1% vs 4.1% and 1.9% vs 1.1%, respectively) but these were not statistically significant. Labor following successful ECV is more likely to result in increased intrapartum intervention rates and poorer neonatal outcomes.

    Aim: evaluation of the effectiveness of radiosynoviorthesis (RSO) in osteoarthritis and other disorders with concomitant synovitis versus rheumatoid arthritis by means of a standardized questionnaire. Patients, methods: 803 RSO treatments were monitored in 691 patients by standardized questionnaires of 7 centers in 3 countries. Patients were assigned to 3 groups according to their age (20-40, 41-60, 61-80 years). Additionally, the data were analyzed separately for patients with rheumatoid arthritis (group A) and those with osteoarthritis, psoriasis arthritis, pigmental villonodular synovitis or persistent effusions after joint replacement (group B). Results: ameliorations of joint pain, swelling/effusion or flexibility were found in 80% of group A and 56% of group B (p <0.01). Quality of life improved in 78% of group A and 59% of group B (p <0.01). The response rate was similar for small- and large-sized joints in group A, but significantly higher for large-sized joints in group B (p <0.01). The positive effects on joint pain, swelling/effusion or flexibility lasted longer in group A (p <0.01). Repeated RSOs were as effective as initial ones. The clinical outcome was neither influenced by age, nor gender, nor transient immobilisation for 48 hours after RSO. Conclusion: although slightly more efficient in rheumatoid arthritis, RSO represents an effective treatment option also in osteoarthritis and other disorders with concomitant synovitis. (orig.)

    This study investigated the current management practices associated with stock herding dogs on Australian farms. A parallel goal was to determine whether these practices and the characteristics of the dog handlers were associated with success rates. Success rate refers to the proportion of dogs acquired by the farmer that were retained as working dogs. Data on a total of 4,027 dogs were obtained through The Farm Dog Survey which gathered information from 812 herding dog owners around Australia. Using logistic regression, significant associations were identified between success rate and seven variables: dog breed, housing method, trial participation, age of the dog at acquisition, electric collar use, hypothetical maximum treatment expenditure and the conscientiousness score of the owner's personality. These findings serve as a guide to direct further research into ways of optimising herding dog performance and welfare. They emphasise the importance of not only examining the genetic predispositions of the working dog but also the impact the handler can have on a dog's success in the workplace. PMID:25136828

    To evaluate the premise that skeletal anchorage with SAS miniplates are highly successful and predictable for a range of complex orthodontic movements. This retrospective cross-sectional analysis consisted of 421 bone plates placed by one clinician in 163 patients (95 female, 68 male, mean age 29.4 years ± 12.02). Simple descriptive statistics were performed for a wide range of malocclusions and desired movements to obtain success, complication, and failure rates. The success rate of skeletal anchorage system miniplates was 98.6%, where approximately 40% of cases experienced mild complications. The most common complication was soft tissue inflammation, which was amenable to focused oral hygiene and antiseptic rinses. Infection occurred in approximately 15% of patients where there was a statistically significant correlation with poor oral hygiene. The most common movements were distalization and intrusion of teeth. More than a third of the cases involved complex movements in more than one plane of space. The success rate of skeletal anchorage system miniplates is high and predictable for a wide range of complex orthodontic movements.

    Intussusception is a common surgical emergency in infants and children. The incidence of intussusception is from one to four per 2,000 infants and children. If there is no peritonitis, perforation sign on abdominal radiographic studies, and nonresponsive shock, nonoperative reduction by pneumatic or hydrostatic enema can be performed. The purpose of this study was to compare the success rates of both the methods. Two institutional retrospective cohort studies were performed. All intussusception patients (ICD-10 code K56.1) who had visited Chiang Mai University Hospital and Siriraj Hospital from January 2006 to December 2012 were included in the study. The data were obtained by chart reviews and electronic databases, which included demographic data, symptoms, signs, and investigations. The patients were grouped according to the method of reduction followed into pneumatic reduction and hydrostatic reduction groups with the outcome being the success of the reduction technique. One hundred and seventy episodes of intussusception occurring in the patients of Chiang Mai University Hospital and Siriraj Hospital were included in this study. The success rate of pneumatic reduction was 61% and that of hydrostatic reduction was 44% (P=0.036). Multivariable analysis and adjusting of the factors by propensity scores were performed; the success rate of pneumatic reduction was 1.48 times more than that of hydrostatic reduction (P=0.036, 95% confidence interval [CI] =1.03-2.13). Both pneumatic and hydrostatic reduction can be performed safely according to the experience of the radiologist or pediatric surgeon and hospital setting. This study showed that pneumatic reduction had a higher success rate than hydrostatic reduction.

  3. Female song rate and structure predict reproductive success in a socially monogamous bird.

    Full Text Available Bird song is commonly regarded as a male trait that has evolved through sexual selection. However, recent research has prompted a re-evaluation of this view by demonstrating that female song is an ancestral and phylogenetically widespread trait. Species with female song provide opportunities to study selective pressures and mechanisms specific to females within the wider context of social competition. We investigated the relationship between reproductive success and female song performance in the New Zealand bellbird (Anthornis melanura, a passerine resident year round in New Zealand temperate forests. We monitored breeding behavior and song over three years on Tiritiri Matangi Island. Female bellbirds contributed significantly more towards parental care than males (solely incubating young and provisioning chicks at more than twice the rate of males. Female song rate in the vicinity of the nest was higher than that of males during incubation and chick-rearing stages but similar during early-nesting and post-breeding stages. Using GLMs, we found that female song rates during both incubation and chick-rearing stages strongly predicted the number of fledged chicks. However, male song rate and male and female chick provisioning rates had no effect on fledging success. Two measures of female song complexity (number of syllable types and the number of transitions between different syllable types were also good predictors of breeding success (GLM on PC scores. In contrast, song duration, the total number of syllables, and the number of ‘stutter’ syllables per song were not correlated with fledging success. It is unclear why male song rate was not associated with reproductive success and we speculate that extra-pair paternity might play a role. While we have previously demonstrated that female bellbird song is important in intrasexual interactions, we clearly demonstrate here that female song predicts reproductive success. These results, with others

    Full Text Available Bird song is well studied in males as a sexually selected behavior. However, although song is also common among females, it is infrequently examined and poorly understood. Research suggests that song is often used as a resource defense behavior and is important in female-female competition for limited resources, e.g. mates and territories. If so, song should be positively related to fitness and related to other resource defense behaviors, but this possibility has rarely been explored. Here we examine fitness estimates in relation to spontaneous song rates and song rates in response to a simulated intruder (playback, in the superb fairy-wren (Malurus cyaneus, a cooperatively breeding songbird. We also determine how song rates relate to other territorial defense behaviors. Song rate in response to playback, but not spontaneous song rate, was positively related to nest success and the number of fledglings produced by successful females. Further, response song rate was also correlated with other territorial defense behaviors (latency to respond and flights. This evidence supports the hypothesis that female song may be used in the context of female-female competition to improve access to limited reproductive resources, and suggests that song may provide direct fitness benefits.

    Over half of the world's forests are disturbed, and the rate at which ecosystem processes recover after disturbance is important for the services these forests can provide. We analyze the drivers' underlying changes in rates of key ecosystem processes (biomass productivity, litter productivity, actual litter decomposition, and potential litter decomposition) during secondary succession after shifting cultivation in wet tropical forest of Mexico. We test the importance of three alternative drivers of ecosystem processes: vegetation biomass (vegetation quantity hypothesis), community-weighted trait mean (mass ratio hypothesis), and functional diversity (niche complementarity hypothesis) using structural equation modeling. This allows us to infer the relative importance of different mechanisms underlying ecosystem process recovery. Ecosystem process rates changed during succession, and the strongest driver was aboveground biomass for each of the processes. Productivity of aboveground stem biomass and leaf litter as well as actual litter decomposition increased with initial standing vegetation biomass, whereas potential litter decomposition decreased with standing biomass. Additionally, biomass productivity was positively affected by community-weighted mean of specific leaf area, and potential decomposition was positively affected by functional divergence, and negatively by community-weighted mean of leaf dry matter content. Our empirical results show that functional diversity and community-weighted means are of secondary importance for explaining changes in ecosystem process rates during tropical forest succession. Instead, simply, the amount of vegetation in a site is the major driver of changes, perhaps because there is a steep biomass buildup during succession that overrides more subtle effects of community functional properties on ecosystem processes. We recommend future studies in the field of biodiversity and ecosystem functioning to separate the effects of

    This study examined the perceived effort, success rates and kinematics for three push strategies in a simulated lateral patient transfer (horizontal slide). Thirteen healthy subjects (four males) completed three repetition pushing loads of 6, 10 and 14 kg in random order; with a spontaneous push strategy, then with a straight-back bent-knees (squat) strategy and the preparatory pelvic movement ('rockback') strategy in random order. Perceived effort and kinematic parameters measured at the onset of movement and at maximum push excursion were compared between strategies and between loads with repeated measures ANOVA. The spontaneous and 'rockback' strategies achieved the pushing task with less perceived effort across all loads than the squat push (P pushing the 14 kg load using a squat strategy, which contrasted with 12/13 participants when the spontaneous strategy or the 'rockback' strategy was used. Forward movement of the pelvis and forward trunk inclination may be positively associated with lower perceived effort in the push task. Practitioner Summary: In a manual-handling task that simulated a lateral patient transfer (horizontal slide), perceived effort and success rates of three push strategies were compared. A straight-back bent-knees push (squat) strategy demonstrated greater perceived effort and lower success rates than a spontaneous push strategy, or a push strategy with preparatory 'rockback' pelvic movement.

    To evaluate the success rate of a low-dose (50 % mAs reduction) computed tomography (CT) biopsy technique. This protocol was adopted based on other successful reduced-CT radiation dose protocols in our department, which were implemented in conjunction with quality improvement projects. The technique included a scout view and initial localizing scan with standard dose. Additional scans obtained for further guidance or needle adjustment were acquired by reducing the tube current-time product (mAs) by 50 %. The radiology billing data were searched for CT-guided musculoskeletal procedures performed over a period of 8 months following the initial implementation of the protocol. These were reviewed for the type of procedure and compliance with the implemented protocol. The compliant CT-guided biopsy cases were then retrospectively reviewed for patient demographics, tumor pathology, and lesion size. Pathology results were compared to the ultimate diagnoses and were categorized as diagnostic, accurate, or successful. Of 92 CT-guided procedures performed during this period, two were excluded as they were not biopsies (one joint injection and one drainage), 19 were excluded due to non-compliance (operators neglected to follow the protocol), and four were excluded due to lack of available follow-up in our electronic medical records. A total of 67 compliant biopsies were performed in 63 patients (two had two biopsies, and one had three biopsies). There were 32 males and 31 females with an average age of 50 (range, 15-84 years). Of the 67 biopsies, five were non-diagnostic and inaccurate and thus unsuccessful (7 %); five were diagnostic but inaccurate and thus unsuccessful (7 %); 57 were diagnostic and accurate thus successful (85 %). These results were comparable with results published in the radiology literature. The success rate of CT-guided biopsies using a low-dose protocol is comparable to published rates for conventional dose biopsies. The implemented low-dose protocol

    1999-02-01

    Soil net N-mineralization rate was measured along a successional gradient in salt-marsh sites that were grazed by vertebrate herbivores, and in 5-year-old exclosures from which the animals were excluded. Mineralization rate was significantly higher at ungrazed than at grazed sites. In the absence of grazing, mineralization rate increased over the course of succession, whereas it remained relatively low when sites were grazed. The largest differences in mineralization rate between grazed and ungrazed sites were found at late successional stages where grazing pressure was lowest. The amount of plant litter was significantly lower at grazed sites. In addition, the amount of litter and potential litter (non-woody, live shoots) was linearly related to net N-mineralization rate. This implies that herbivores reduced mineralization rate by preventing litter accumulation. Bulk density was higher at grazed salt-marsh sites than at ungrazed sites. This factor may also have contributed to the differences in net N-mineralization rate between grazed and ungrazed sites.

    Orthodontic mini-implants are important devices for successful anchorage management in orthodontics; however, the survival of these devices depends on several clinical factors. The aim of our study was to calculate the success and complication rates of orthodontic mini-implants. In this retrospective study, patients of our orthodontic department were enrolled, getting overall 59 orthodontic mini-implants during their orthodontic treatment in a 2-year period. Every patient had one or more of the 1.6 mm × 8 mm in size self-drilling mini-implants (Jeil Dual Top Anchor System, Jeil Medical Corp., Seoul, Korea). Screw loading was performed immediately after insertions, keeping tension forces under 150 g. Soft tissue and bone infections, implant mobility and screw loss, implant fracture, and neighboring tooth injury were registered. Relationships between variables were tested using the Chi-square test for statistical significance. The success rate of the orthodontic mini-implants was 89.8% in this study while the average loading period was 8.1 months. Soft-tissue infections varied between 6.3% and 33.3% of the cases while screw mobility varied between 3.1% and 20.8% of the cases regarding the anatomic localization. Screw mobility was significantly more frequent in the buccal fold than in the palate (P = 0.034). Screw mobility was significantly more frequent in the buccal fold than in the palate (P = 0.034) and screw mobility was found more frequently in case of intrusions than by extrusions (P = 0.036). The overall success rate of mini-implants was found acceptable in this study, however, screw mobility in the buccal fold showed a high incidence, suggesting the thorough consideration of the immediate loading by buccal mini-implants.

    Full Text Available Our aim was to investigate differences in teacher stress and perceptions of school climate among teachers from schools with differing matriculation success rates in the Limpopo province of South Africa. Two schools with matric pass rates of 100% and two schools with matric pass rates of less than 25% were selected from a list of schools provided by the province's Educational District Circuit. The schools were matched in terms of area, size, resources, and equipment. Thirty-three teachers from the high performing schools and forty-two teachers from the poor performing schools participated in the study. Student's t tests were used to assess the differences between the schools on the variables under investigation, and the results showed the teachers' experience of stress across the different schools was not significantly different, but significant differences did emerge with regard to school climate. The implications of these findings for the study population are discussed.

    To determine the success rate, oral morbidity and functional outcomes of redo buccal mucosa graft urethroplasty (BMGU) for treatment of stricture recurrence after previous BMGU. We included 50 patients who underwent redo BMGU between February 2009 and September 2014. Patients' charts and non-validated questionnaires were reviewed. The primary endpoint was success rate, defined as stricture-free survival. Stricture recurrence was defined as any postoperative claims of catheterization, dilatation, urethrotomy or repeat urethroplasty, or a maximum urinary flow rate <15 mL/s, and a stricture was consecutively verified in a combined cysto-urethrogram or cystoscopy at annual follow-up visit. The secondary endpoint was oral morbidity. Additional endpoints were erectile function, urinary continence and patients' satisfaction. Redo BMGU was performed for bulbar (71.4%) or penile (28.6%) recurrent strictures. The mean (median; range) follow-up was 25.6 (15.5; 3-70) months. Stricture recurrence occurred in 18.0% of patients within a mean (median; range) of 13.8 (9.0; 3-36) months. Stricture-free survival at 12, 24 and 36 months was 91.2, 86.2 and 80.8%, respectively. The majority of the patients (97.0%) reported no or only mildly changed salivation or problems in opening of the mouth. Severe or very severe oral numbness occurred in 13.5% of patients. Oral problems in daily life were a moderate or severe burden to 13.6 and 2.7% of the patients, respectively, while 75.0% of the patients reported improved quality of life compared with preoperative status. The success rate and oral morbidity of redo BMGU are almost the same as outcomes of primary BMGU. Oral numbness was the most frequently reported oral disorder. © 2016 The Authors BJU International © 2016 BJU International Published by John Wiley & Sons Ltd.

    Full text of publication follows. Objective: to see if diagnostic whole body scan (DxWBS) performed with I-131 prior diminishes the success rate of initial radioiodine remnant ablation (RRA) compared to I-123 DxWBS in differentiated thyroid cancer patients. Material and methods: consecutive thyroid cancer patients who received total thyroidectomy for differentiated thyroid cancer and then high dose RRA (either 100 mCi or 150 mCi) within 6 months were included. DxWBSs were performed with I-123 or with I-131. Prior to the DxWBSs, all patients followed strict low iodine diet for 2 weeks and withdrew hormone to stimulate TSH above 30 mIU/l. Patients with extra-thyroidal extension of tumor, lymph node metastasis, or distant metastasis were excluded. The initial RRA was defined as successful if the next DxWBS done 6 months to 1 year later was negative and stimulated thyroglobulin level was below 2 ng/ml. Results: of 71 patients who had I-123 DxWBSs, 31 patients went on to receive RRA with 100 mCi and 40 patients received 150 mCi. Of 73 patients who had I-131 DxWBSs, 66 received 100 mCi and 7 patients received 150 mCi. The overall success rate was 79% for patients who had I-123 DxWBS prior to RRA (68% for 100 mCi and 86% for 150 mCi), and 68% for patient who had I-131 DxWBSs (68% for 100 mCi and 71% for 150 mCi). Conclusion: for patients who received 100 mCi, the RRA success rate was the same for I-123 DxWBS and I-131 DxWBS. For patients treated with 150 mCi, the success rate may be lower in patients who receive RRA following DxWBS with I-131 compared to DxWBS with I-123. (authors)

  15. An Analytic Model for the Success Rate of a Robotic Actuator System in Hitting Random Targets.

    Autonomous robotic systems are increasingly being used in a wide range of applications such as precision agriculture, medicine, and the military. These systems have common features which often includes an action by an "actuator" interacting with a target. While simulations and measurements exist for the success rate of hitting targets by some systems, there is a dearth of analytic models which can give insight into, and guidance on optimization, of new robotic systems. The present paper develops a simple model for estimation of the success rate for hitting random targets from a moving platform. The model has two main dimensionless parameters: the ratio of actuator spacing to target diameter; and the ratio of platform distance moved (between actuator "firings") to the target diameter. It is found that regions of parameter space having specified high success are described by simple equations, providing guidance on design. The role of a "cost function" is introduced which, when minimized, provides optimization of design, operating, and risk mitigation costs.

    Inferior alveolar nerve block (IANB) of the mandible is commonly used in the oral cavity as an anesthetic technique for dental procedures. This study evaluated the success rate of the first IANB administered by dental practitioners. Volunteer dental practitioners at Mahidol University who had never performed an INAB carried out 106 INAB procedures. The practitioners were divided into 12 groups with their advisors by randomized control trials. We recorded the success rate via pain visual analog scale (VAS) scores. A large percentage of the dental practitioners (85.26%) used the standard method to locate the anatomical landmarks, injecting the local anesthetic at the correct position, with the barrel of the syringe parallel to the occlusal plane of the mandibular teeth. Further, 68.42% of the dental practitioners injected the local anesthetic on the right side by using the left index finger for retraction. The onset time was approximately 0-5 mins for nearly half of the dental practitioners (47.37% for subjective onset and 43.16% for objective onset), while the duration of the IANB was approximately 240-300 minutes (36.84%) after the initiation of numbness. Moreover, the VAS pain scores were 2.5 ± 1.85 and 2.1 ± 1.8 while injecting and delivering local anesthesia, respectively. The only recorded factor that affected the success of the local anesthetic was the administering practitioner. This reinforces the notion that local anesthesia administration is a technique-sensitive procedure.

    Full Text Available The paper outlines the importance of balanced management of hard and soft key success factors, combining the economic logic of corporate performance and human capital through an integrated approach to mergers and acquisitions. The study, based on a questionnaire and interviews, suggests that the achievement level ofmergers and acquisitions’ objectives of acquiring companies in Slovenia should be comparable to findings of similar studies; namely, the objectives that drove the deal were met only half the time. The results indicate that five hard success factors – a professional target search and due diligence, a realistic assessment of synergies, theright mix of financial sources, a detailed post-acquisition integration plan already prepared in the pre-deal phase and its speedy implementation – and five soft success factors – a new “combined” organizational culture, a competent management team, innovative employees, efficient and consistent communication and a creative business environment – are becoming increasingly relevant. Even though they differ in their importance for individual companies in the sample, they are all considered essential to increasing the success rate of corporate combinations

    Central venous catheterization (CVC) is an important procedure in emergency departments (EDs). Despite existence of ultrasonography (US) devices in every ED, CVC is done using anatomical landmarks in many EDs in Iran. This study aimed to compare the traditional landmark method vs. US-guided method of CVC placement in terms of complications and success rate. In this randomized controlled trial, patients who were candidate for internal jugular vein catheterization, and referred to Baqiyatallah Hospital ED were randomly allocated into US-guided CVC and anatomical landmarks guided CVC groups. Central vein access time, number of attempts, success rate, and complications in each group were evaluated. Mann-Whitney U, chi-square and Fisher exact tests along with Pearson and Spearman correlation coefficients were used to analyze the data. Out of 100 patients, 56 were male and 44 were female. No significant differences were found between the US-guided and traditional landmark methods of CVC insertion in terms of age, gender, BMI, and site of catheter insertion. The mean access time was significantly lower in the US-guided group (37.12 ± 17.33 s vs. 63.42 ± 35.19 s, P < 0.001). The mean number of attempts was also significantly lower in the US-guided group (1.12 ± 0.3 vs. 1.58 ± 0.64 times, P < 0.001). Eighty-eight percent of patients in the US-guided group were catheterized in the first attempt, while 50% of patients in the traditional landmark group were catheterized in the second or more attempts (P < 0.001). The success rate was 100% in the US-guided group, while it was 88% in the landmark group (P = 0.013). Moreover, the rate of complications was significantly lower in the US-guided group (4% vs. 24%, P = 0.004). The US-guided method for CVC placement was superior to the traditional landmark method in terms of access time, number of attempts, success rate, and fewer complications.

    Full Text Available Aim To evaluate the correlation between the success of pregnancy through in vitro fertilization and maternal age. Methods Assessment of pregnancy was performed in eight in vitro fertilization centers in Indonesia: Harapan Kita Pediatric and Obstetric Hospital from 1997 to 2001, and seven in vitro fertilization centers in Indonesia. Follicular induction was performed through the long protocol, short protocol and natural cycle. Insemination was performed through ICSI (intra cytoplasmic sperm injection on petri dish. Spermatozoa were obtained through masturbation, testicular biopsy and epididimical biopsy. A successful pregnancy was indicated chemically, with the presence of fetal heart beat and the birth of a baby (take home baby. Results There was a 34% pregnancy rate for the age group below 30 years, 33.75% for those between 31 and 35 years olds, and 26% for the age group 36 to 40 years old, and 8% for the age group above 40 years. Conclusion The higher the maternal age, the lower pregnancy rate. In other words, the higher the maternal age, the higher the rate of miscarriage.

    Although placement of a retropubic mid-urethral slings (MUS) is one of the gold standard surgical treatments for stress urinary incontinence, new devices are poorly evaluated before marketing. We compared TVT-EXACT™ (TVT-E), a new device expected to reduce bladder injuries, with the historically described bottom-to-top TVT™ (TVT). This retrospective study compared TVT-E (n=49) and TVT (n=49). The main outcomes were the prevalence of complications (bladder injuries, immediate postoperative pain, perioperative complications, etc.) and the short-term success rate (no reported urinary leakage and negative cough test) of both MUSs. Minimum follow-up was 12 months. The characteristics of the two groups were comparable. The prevalence of bladder injury for TVT-E and TVT was 8% and 6%, respectively (p=1). The intensity of immediate postoperative pain (VAS/100) was lower following TVT-E than after TVT (8.0 vs. 15.9, p=0.01). The first post-void residual was increased in the TVT-E group (153.9 vs. 78.9mL, p=0.045), and there were more postoperative bladder outlet obstruction (BOO) symptoms in the TVT-E group (24% vs. 6%, p=0.02). However, there was no difference when considering only de novo BOO (14% vs. 4%, p=0.16). The prevalence of peri- and post-operative complications was equal in the two groups. The success rate was similar at 12 months of follow-up (80 vs. 82%, p=1). The prevalence of bladder injury was unchanged with TVT-EXACT™ compared with TVT™, but post-operative pain was decreased. The success rate of both retropubic MUSs was similar at 12 months of follow-up. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Background: The objective of this study was to identify the prognostic factors that influence the outcome of ovarian stimulation with intrauterine insemination (IUI) cycles in couples with different infertility etiology. Materials and Methods: This retrospective study was performed in data of 1348 IUI cycles with ovarian stimulation by clomiphene citrate (CC) and/or gonadotropins in 632 women with five different infertility etiology subgroups at Akbarabbadi Hospital, Tehran, Iran. Results: The pregnancy rate (PR)/ cycle was highest (19.9%) among couples with unexplained infertility and lowest (10.6%) in couples with multiple factors infertility. In cases of unexplained infertility, the best PRs were seen after CC plus gonadotropins stimulation (26.3%) and with inseminated motile sperm count>30×106 (21.9%), but the tendency didn’t reach statistical significant. In the ovarian factor group, the best PRs were observed in women aged between 30 and 34 years (20.8%), with 2-3 preovulatory follicles (37.8%) and infertility duration between 1and 3 years (20.8%), while only infertility duration (p=0.03) and number of preovulatory follicles (p=0.01) were statistically significant. Multiple logistic regression analysis determined that number of preovulatory follicles (p=0.02), duration of infertility (p=0.015), age (p=0.019), infertility etiology (p=0.05) and stimulation regimen (p=0.01) were significant independent factors in order to predict overall clinical PR. Conclusion: The etiology of infertility is important to achieve remarkable IUI success. It is worth mentioning that within different etiologies of infertility, the demographic and cycles characteristics of couples did not show the same effect. Favorable variables for treatment success are as follows: age infertility ≤5 years and a cause of infertility except of multiple factors. PMID:24520471

    Ridge preservation is any procedure that takes place at the time of, or shortly after an extraction, to minimise resorption of the ridge and maximise bone formation within the socket. The aim of this project is to investigate the outcome of implant treatment following ridge preservation and compare it to an ungrafted implant control group. Following ethics approval, an electronic and manual search of patient records was conducted, and appropriate cases of implant placement following a ridge preservation procedure were identified. Forty-two patients with 51 implants at ridge-preserved sites were examined by one author (PA) with the following parameters assessed at each implant: pocket probing depth, bleeding on probing, presence/absence of plaque and radiographic bone loss. Clinical and radiographic findings were compared to an ungrafted implant control group and analysed by years in function. There was a 100% survival rate of implants in ridge-preserved sites. In the majority of cases, ridge preservation was performed in the anterior maxilla with a flap raised and the use of deproteinised bovine bone mineral and collagen membrane materials. The mean time in function was 31 (±24) months with a range of 2-102 months. Differences in the mean PPD, BOP, plaque index and radiographic bone loss were not statistically significant between implants at ridge-preserved or ungrafted sites. The overall success rate was around 58% for ungrafted implants and around 51% for implants in ridge-preserved sites. However, this difference was not statistically significant. In this retrospective study, implant placement at ridge-preserved sites was a predictable procedure that led to very high survival rates and similar success rates to implant placement at ungrafted sites. © 2016 John Wiley & Sons A/S.

    Fertilizer response modelling is an important technical approach to realize metrological fertilization on rice. With the goal of solving the problems of a low success rate of a ternary quadratic polynomial model (TPFM) and to expand the model's applicability, this paper established a ternary non-structural fertilizer response model (TNFM) based on the experimental results from N, P and K fertilized rice fields. Our research results showed that the TNFM significantly improved the modelling success rate by addressing problems arising from setting the bias and multicollinearity in a TPFM. The results from 88 rice field trials in China indicated that the proportion of typical TNFMs that satisfy the general fertilizer response law of plant nutrition was 40.9%, while the analogous proportion of TPFMs was only 26.1%. The recommended fertilization showed a significant positive linear correlation between the two models, and the parameters N 0 , P 0 and K 0 that estimated the value of soil supplying nutrient equivalents can be used as better indicators of yield potential in plots where no N or P or K fertilizer was applied. The theoretical analysis showed that the new model has a higher fitting accuracy and a wider application range.

    The community succession and function change of thermophilic archaea Acidianus brierleyi, Metallosphaera sedula, Acidianus manzaensis and Sulfolobus metallicus were studied by denaturing gradient gel electrophoresis (DGGE) analysis of amplifying 16S rRNA genes fragments and real-time qPCR analysis of amplifying sulfur-oxidizing soxB gene associated with chalcopyrite bioleaching rate at different temperatures and initial pH values. The analysis results of the community succession indicated that temperature and initial pH value had a significant effect on the consortium, and S. metallicus was most sensitive to the environmental change, A. brierleyi showed the best adaptability and sulfur oxidation ability and predominated in various leaching systems. Meanwhile, the leaching rate of chalcopyrite closely related to the consortium function embodied by soxB gene, which could prove a desirable way for revealing microbial sulfur oxidation difference and tracking the function change of the consortium, and for optimizing the leaching parameters and improving the recovery of valuable metals.

    Introduction: Nonoperative management (NOM) has become the treatment of choice for hemodynamically stable patients with blunt splenic injury. Results of outcome after NOM are predominantly based on large-volume studies from level 1 trauma centers in the United States. This study was designed to assess the results of NOM in a relatively low-volume Dutch level 1 trauma center. Methods: An analysis of a prospective trauma registry was performed for a 6-year period before (period 1) and after the introduction and implementation of splenic artery embolization (SAE) (period 2). Primary outcome was the failure rate of initial treatment. Results: A total of 151 patients were reviewed. An increased use of SAE and a reduction of splenic operations during the second period was observed. Compared with period 1, the failure rate after observation in period 2 decreased from 25% to 10%. The failure rate after SAE in period 2 was 18%. The splenic salvage rate (SSR) after observation increased from 79% in the first period to 100% in the second period. During the second period, all patients with failure after observation were successfully treated with SAE. The SSR after SAE in periods 1 and 2 was respectively 100% and 86%. Conclusions: SAE of patients with blunt splenic injuries is associated with a reduction in splenic operations. The failure and splenic salvage rates in this current study were comparable with the results from large-volume studies of level 1 trauma centers. Nonoperative management also is feasible in a relatively low-volume level 1 trauma center outside the United States.

    Full Text Available The globalization of the world market and the flexibility of containerization to adjust to the constant changes in supply and demand of the international goods market, has led to a continuous increase in the portion of the container transport within the international maritime cargo transport. By the increase of the container transport level, the impact and importance of container freight rates have been growing, the variability of which directly reflects on the world economy. The aim of this paper is to analyze the efficiency of actual methods in establishing the container freight rates according to the problems which appear in the container shipping operation and refer to large differences in the weights of the actual transported cargo and the declared cargo in containers. The consequence of is lower freight rates and higher costs of the vessels exploitation, concerning the increase of the bunker oil consumption. The conducted research is based on actual data that have been collected and analyzed from particular container vessel liner services within period of 90 days and casting off from 16 container ports. The proposed measures could increase the level of usability of the transporting ships capacities and enable a more accurate and correct account of sea freight rates. The results of the research have shown that by increasing the control of accuracy of the cargo weight in containers and by improving the model of accounting, the freight rates can increase the incomes of shipping companies maintaining the same level of container traffic, which can have a direct influence on the efficiency of their successful operation.

    Interpretation of Heliophysics wave data requires specialized knowledge of wave phenomena. Users of the virtual wave observatory (VWO) will greatly benefit from a data annotation service that will allow querying of data by phenomenon type, thus helping accomplish the VWO goal to make Heliophysics wave data searchable, understandable, and usable by the scientific community. Individual annotations can be sorted by phenomenon type and reduced into event lists (catalogs). However, in contrast to the event lists, annotation records allow a greater flexibility of collaborative management by more easily admitting operations of addition, revision, or deletion. They can therefore become the building blocks for an interactive Annotation Service with a suitable graphic user interface to the VWO middleware. The VWO Annotation Service vision is an interactive, collaborative sharing of domain expert knowledge with fellow scientists and students alike. An effective prototype of the VWO Annotation Service has been in operation at the University of Massachusetts Lowell since 2001. An expert rating system (ERS) was developed for annotating the IMAGE radio plasma imager (RPI) active sounding data containing 1.2 million plasmagrams. The RPI data analysts can use ERS to submit expert ratings of plasmagram features, such as presence of echo traces resulted from reflected RPI signals from distant plasma structures. Since its inception in 2001, the RPI ERS has accumulated 7351 expert plasmagram ratings in 16 phenomenon categories, together with free-text descriptions and other metadata. In addition to human expert ratings, the system holds 225,125 ratings submitted by the CORPRAL data prospecting software that employs a model of the human pre-attentive vision to select images potentially containing interesting features. The annotation records proved to be instrumental in a number of investigations where manual data exploration would have been prohibitively tedious and expensive

    Full Text Available Research Objective. This study determined the outcome of cardiopulmonary resuscitation (CPR after in-hospital cardiac arrest and factors influencing it in two training hospitals in Ahvaz. Method. Patients hospitalized in the pediatric wards and exposed to CPR during hospital stay were included in the study (September 2013 to May 2014. The primary outcome of CPR was assumed to be the return of spontaneous circulation (ROSC and the secondary outcome was assumed to be survival to discharge. The neurological outcome of survivors was assessed using the Pediatric Cerebral Performance Category (PCPC method. Results. Of the 279 study participants, 138 patients (49.4% showed ROSC, 81 patients (29% survived for 24 hours after the CPR, and 33 patients (11.8% survived to discharge. Of the surviving patients, 16 (48.5% had favorable neurological outcome. The resuscitation during holidays resulted in fewer ROSC. Multivariate analysis showed that longer CPR duration, CPR by junior residents, growth deficiency, and prearrest vasoactive drug infusion were associated with decreased survival to discharge (p<0.05. Infants and patients with respiratory disease had higher survival rates. Conclusion. The rate of successful CPR in our study was lower than rates reported by developed countries. However, factors influencing the outcome of CPR were similar. These results reflect the necessity of paying more attention to pediatric CPR training, postresuscitation conditions, and expansion of intensive care facilities.

    Understanding how both quality and quantity of prey affect the population dynamics of marine predators is a crucial step toward predicting the effects of environmental perturbations on population-level processes. The Junk Food Hypothesis, which posits that energetic content of prey species may influence reproductive capacity of marine top predators regardless of prey availability, has been proposed as a mechanism by which changes in prey populations could affect predator populations in high latitude systems; however, support for this hypothesis has been inconsistent across studies, and further data are needed to elucidate variation in the relative importance of prey quantity and quality, both among predator species and across ecological systems. We tested the relative importance of prey quantity and quality to nestling survival in the eastern brown pelican Pelecanus occidentalis carolinensis across 9 breeding colonies in the northern Gulf of Mexico that varied in underlying availability of a key prey resource, the Gulf menhaden Brevoortia patronus. Both feeding frequency and meal mass were significantly correlated to energy provisioning rates and nestling survival, while energy density of meals had little effect on either metric. Compared to previous results from cold-water systems, we found lower and less variable energy densities (4.4 kJ g-1, vs. 5.2 to 6.5 kJ g-1 in other studies) and lipid content (9% dry mass, vs. 16 to 23% in other studies) of common prey items. While Gulf menhaden was the most common prey species at all colonies, the proportion of menhaden fed to nestlings varied and was not strongly correlated to fledging success. We conclude that quantity rather than quality of prey, particularly small schooling fish, is the main driver of brown pelican reproductive success in this system, and that environmental perturbations affecting biomass, distribution, and abundance of forage fish could substantially affect brown pelican reproductive success.

    Purpose: to analyze the clinical success rate and the findings of magnetic resonance imaging (MRI) after uterine artery embolization of symptomatic leiomyomas (fibroids) of the uterus. Materials and methods: this is a prospective single-center case study of 80 consecutively treated patients, followed for 3-6 months (group I), 7-12 months, (group II), and 13-25 months (group III). MRI was used to determine the uterine volume and size of the dominant leiomyoma. Symptoms and causes requiring repeat interventions were analyzed. Results: significant (p < 0.01) volume reduction of the uterus (median: 34.95% confidence interval [CI]: 30.41 - 41.76%) and dominant leiomyoma (median: 52.07%, CI: 47.71 - 61.57%) was found. The decrease in uterine volume (I-III: 22.68%, 33.56%, 47.93%) and dominant leiomyoma volume (I-III: 41.86%, 62.16%, 73.96%) progressed with the follow-up time. Bleeding resolved significantly (p < 0.0001) in all three follow-up groups (groups I-III: 92.86%, 95.23%, 96.67%). Furthermore, urinary frequency (groups I-III: 70%, 75%, 82.35%) and sensation of pelvic pressure (groups I-III: 42.86%, 60%, 93.75%) improved, which was statistically significant in group III (p < 0.01). The number of leiomyomas correlated (p < 0.05) with improvement of the bleeding and the pelvic pressure. Repeat therapy was necessary for complications in four patients (5%) and for therapeutic failure in three patients (3.8%). Permanent amenorrhea was observed in four patients (5%) of age 45 years or older. Conclusion: uterine artery embolization of uterine leiomyomas has a high clinical success rate with an acceptable incidence of complications and repeat interventions. (orig.)

    Studies using global positioning system (GPS) telemetry rarely result in 100% fix success rates (FSR), which may bias datasets because data loss is systematic rather than a random process. Previous spatially explicit models developed to correct for sampling bias have been limited to small study areas, a small range of data loss, or were study-area specific. We modeled environmental effects on FSR from desert to alpine biomes, investigated the full range of potential data loss (0–100% FSR), and evaluated whether animal body position can contribute to lower FSR because of changes in antenna orientation based on GPS detection rates for 4 focal species: cougars (Puma concolor), desert bighorn sheep (Ovis canadensis nelsoni), Rocky Mountain elk (Cervus elaphus nelsoni), and mule deer (Odocoileus hemionus). Terrain exposure and height of over story vegetation were the most influential factors affecting FSR. Model evaluation showed a strong correlation (0.88) between observed and predicted FSR and no significant differences between predicted and observed FSRs using 2 independent validation datasets. We found that cougars and canyon-dwelling bighorn sheep may select for environmental features that influence their detectability by GPS technology, mule deer may select against these features, and elk appear to be nonselective. We observed temporal patterns in missed fixes only for cougars. We provide a model for cougars, predicting fix success by time of day that is likely due to circadian changes in collar orientation and selection of daybed sites. We also provide a model predicting the probability of GPS fix acquisitions given environmental conditions, which had a strong relationship (r 2 = 0.82) with deployed collar FSRs across species.

    To review the long-term outcomes of transecting versus non-transecting urethroplasty to repair bulbar urethral strictures. A retrospective review was conducted of 342 patients who underwent anterior urethroplasty performed by a single surgeon from 2003 to 2014. Patients were excluded from further analysis if there had been prior urethroplasty, stricture location outside the bulbous urethra, or age urethroplasty. In the non-transecting group, surgical techniques used included non-transecting anastomotic urethroplasty and dorsal and/or ventral buccal grafting. The primary endpoint was stricture resolution in transecting vs. non-transecting bulbar urethroplasty. Success was defined as freedom from secondary procedures including dilation, urethrotomy, or repeat urethroplasty. One hundred and fifty-two patients met inclusion criteria. At a mean follow-up of 65 months (range: 10-138 months), stricture-free recurrence in the transecting and non-transecting groups was similar, 83% (n = 85/102) and 82% (n = 41/50), respectively (p = 0.84). Surgical technique (p = 0.91), stricture length (p = 0.8), and etiology (p = 0.6) did not affect stricture recurrence rate on multivariate analysis. There was no difference detected in time to stricture recurrence (p = 0.21). In this retrospective series, transecting and non-transecting primary bulbar urethroplasty resulted in similar long-term stricture resolution rate. Prospective studies are needed to determine what differences may present in outcomes related to sexual function and long-term success.

    Purpose: To evaluate peri-procedural, early and late complications as well as patients' acceptance of combined ultrasound and fluoroscopy guided radiological port catheter implantation. Materials and methods: In a retrospective analysis, all consecutive radiological port catheter implantations (n = 299) between August 2002 and December 2004 were analyzed. All implantations were performed in an angio suite under analgosedation and antibiotic prophylaxis. Port insertion was guided by ultrasonographic puncture of the jugular (n = 298) or subclavian (n = 1) vein and fluoroscopic guidance of catheter placement. All data of the port implantation had been prospectively entered into a database for interventional radiological procedures. To assess long-term results, patients, relatives or primary physicians were interviewed by telephone; additional data were generated from the hospital information system. Patients and/or the relatives were asked about their satisfaction with the port implantion procedure and long-term results. Results: The technical success rate was 99% (298/299). There were no major complications according to the grading system of SIR. A total of 23 (0.33 per 1000 catheter days) complications (early (n = 4), late (n = 19)) were recorded in the follow-period of a total of 72,727 indwelling catheter days. Infectious complications accounted for 0.15, thrombotic for 0.07 and migration for 0.04 complications per 1000 catheter days. Most complications were successfully treated by interventional measures. Twelve port catheters had to be explanted due to complications, mainly because of infection (n = 9). Patients' and relatives' satisfaction with the port catheter system was very high, even if complications occurred. Conclusion: Combined ultrasound and fluoroscopy guided port catheter implantation is a very safe and reliable procedure with low peri-procedural, early and late complication rate. The intervention achieves very high acceptance by the patients and

    Various vena cava filters (VCF) are designed with the ability to be retrieved percutaneously. Yet, despite this option most of them remain in the inferior vena cava (IVC). To report our experience in the placement and retrieval of three different types of VCFs, and to compare the indications for their insertion and retrieval as reported in the literature. During a 5 year period three types of retrievable VCF (ALN, OptEase, and Celect) were inserted in 306 patients at the Rabin Medical Center (Beilinson and Hasharon hospitals). Indications, retrieval rates, median time to retrieval, success and complication rates were viewed and assessed in the three groups of filter types and were compared with the data of similar studies in the literature. Of the 306 VCFs inserted, 31 (10.1%) were retrieved with equal distribution in the three groups. In most patients the reason for filter insertion was venous thromboembolic events (VTE) and contraindications to anticoagulant therapy. Mean age was 68.38 ± 17.5 years (range 18-99) and was noted to be significantly higher compared to similar studies (53-56 years) (P < 0.0001). Multi-trauma patients were significantly older (71.11 ± 14.99 years) than post-pulmonary embolism patients (48.03 ± 20.98 years, P < 0.0001) and patients with preventive indication (26.00 ± 11.31, P < 0.0001). The mean indwelling time was 100.6 ± 103.399 days. Our results are comparable with the results of other studies, and there was no difference in percentage of retrieval or complications between patients in each of the three groups. In 1 of 10 patients filters should be removed after an average of 3.5 months. All three IVC filter types used are safe to insert and retrieve.

  1. Improvement of Automated POST Case Success Rate Using Support Vector Machines

    an 8% pass rate, tens or hundreds of thousands of reps may be needed to be confident that the best repetition is at least close to the global optima. However, typical design study time constraints require that fewer repetitions be attempted, sometimes resulting in seed points that have only a handful of successful completions. If a small number of successful repetitions are used to generate a seed point, the graph method may inherit some inaccuracies as it chains DOE cases from the non-global-optimal seed points. This creates inherent noise in the graph data, which can limit the accuracy of the resulting surrogate models. For this reason, the goal of this work is to improve the seed point generation method and ultimately the accuracy of the resulting POST surrogate model. The work focuses on increasing the case pass rate for seed point generation.

    Objective: To determine the rates of diagnostic success and complications of computed tomography (CT)-guided percutaneous biopsy of bone lesions suspected for malignancy. Materials and Methods: Retrospective study including 186 cases of CT-guided percutaneous biopsies of bone lesions in the period from January, 2010 to December, 2012. All the specimens were obtained with 8-10 gauge needles. The following data were collected: demographics, previous history of malignancy, data related to the lesion, to the procedure, and to histological results. Results: Most patients were women (57%), and the mean age was 53.0 ± 16.4 years. In 139 cases (74.6%), there was diagnostic suspicion of metastasis and the most common primary tumors were breast (32.1%) and prostate (11.8%). The bones most commonly involved were spine (36.0%), hip (32.8%) and long bones (18.3%). Complications occurred in only three cases (1.6%) including bone fracture, paraesthesia with functional impairment, and needle breakage requiring surgical removal. The specimens collected from 183 lesions (98.4%) were considered appropriate for diagnosis. Malignant results were more frequently found in patients who had a suspected secondary lesion and history of known malignancy (p < 0.001), and in patients who underwent PET/CT-guided procedures (p = 0.011). Conclusion: CT-guided percutaneous biopsy is a safe and effective procedure for the diagnosis of suspicious bone lesions. (author)

    Basal metabolic rate (BMR) is one of the most widely used metabolic variables in endotherm ecological and evolutionary physiology. Surprisingly few studies have investigated how BMR is influenced by experimental and analytical variables over and above the standardized conditions required for minimum normothermic resting metabolism. We tested whether avian BMR is affected by habituation to the conditions experienced during laboratory gas exchange measurements by measuring BMR five times in succession in budgerigars (Melopsittacus undulatus) housed under constant temperature and photoperiod. Both the magnitude and the variability of BMR decreased significantly with repeated measurements, from 0.410 ± 0.092 W (n = 9) during the first measurement to 0.285 ± 0.042 W (n = 9) during the fifth measurement. Thus, estimated BMR decreased by ∼30% within individuals solely on account of the number of times they had previously experienced the experimental conditions. The most likely explanation for these results is an attenuation with repeated exposure of the acute stress response induced by birds being handled and placed in respirometry chambers. Our data suggest that habituation to experimental conditions is potentially an important determinant of observed BMR, and this source of variation needs to be taken into account in future studies of metabolic variation among individuals, populations, and species.

    The objective was to examine the success and immediate complication rates in a large series of radiologically placed tunneled central venous catheters. We prospectively recorded the success and immediate complication rates in 880 consecutive radiologically placed tunneled central venous catheters. We also recorded the indication for placement, the success of placement, the number of passes required, and whether a double- or single-wall puncture occurred. Hemodialysis was the most common indication for long-term venous access. Venous access was successful in all patients, and catheter placement was successful in 99.4% of patients, with only five failed placements. All patients in whom placement was initially unsuccessful underwent successful placement the same day. All catheters were placed using real-time sonographic guidance. Most were placed in an internal jugular vein, with 87.4% requiring only a single needle pass. The immediate complication rate was only 4.0%, and no major complications occurred. To our knowledge, this series is the largest for which the immediate complication and success rates for radiologically placed central venous catheters have been reported. Our results suggest that radiologic placement of tunneled central venous catheters is a safe and effective alternative to surgery.

    To compare the technical success and complication rates of push versus pull gastrostomy tubes in cancer patients, and to examine their dependence on operator experience. A retrospective review was performed of 304 cancer patients (170 men, 134 women; mean age 60.3±12.6 [SD], range: 19-102 years) referred for primary gastrostomy tube placement, 88 (29%) of whom had a previously unsuccessful attempt at percutaneous endoscopic gastrostomy (PEG) placement. Analyzed variables included method of insertion (push versus pull), indication for gastrostomy, technical success, operator experience, and procedure-related complications within 30 days of placement. Gastrostomy tubes were placed for feeding in 189 patients and palliative decompression in 115 patients. Technical success was 91%: 78% after endoscopy had previously been unsuccessful and 97% when excluding failures associated with prior endoscopy. In the first 30 days, there were 29 minor complications (17.2%) associated with push gastrostomies, and only 8 minor complications (7.5%) with pull gastrostomies (Ptechnical success rates for more versus less experienced operators. Pull gastrostomy tube placement had a lower rate of complications than push gastrostomy tube placement, especially when the indication was decompression. The technical success rate was high, even after a failed attempt at endoscopic placement. Both the rates of success and complications were independent of operator experience.

    Aim: A review of complication and success rates of the 'mixed' technique in percutaneous nephrostomy using both the Seldinger and one-step techniques in dilated and non-dilated systems. Materials and methods: We retrospectively analysed 500 percutaneous nephrostomies in dilated an non-dilated systems in 353 patients from 2006 to 2007 (208 males (range 19-95 years), 127 females (range 27-91 years) and 21 children (range 3 months-16 years: 6 females, 15 males)). Percutaneous nephrostomy was considered successful if catheter was placed in renal pelvis and drained urine spontaneously. Successful percutaneous nephrostomies were classified as primary (renal system drained instantly) or postponed (drainage achieved within 24 h after initial failure). Number of complications was registered. Results: All of the 500 nephrostomies were successful within 24 h (96.2% primary; 3.8% postponed). The success rate of primary nephrostomy in dilated and non-dilated systems was 98.2% and 82%, respectively. Major complications occurred in 0.45% and minor complications in 14.2%. Conclusion: Percutaneous nephrostomy using the 'mixed' technique is very successful in dilated systems, is not superior to other PCN techniques in non-dilated systems and has a very low rate of major complications.

    Haemorrhage from the injured extremity is a significant cause of preventable death in military settings. This study evaluated the effect of training on the efficacy of the combat application tourniquet (CAT) and to define standards for military personnel. Participants from a training tank battalion were randomised. Data collected included age, body mass index, mean arterial pressure, hand dominance, femoral artery diameter and skin thickness. The study involved tourniquet application times (AT) and application success rates in basic, after-training and eyes-closed phases. Doppler ultrasound was used to identify the presence or absence of popliteal, radial and ulnar artery pulses. A total of 102 trainees participated. In the after-training phase, the left and right upper extremity ATs were 35 ± 13.1 s, and 34.8 ± 13.5 s and the right and left lower extremity ATs were 20.6 ± 6.0 s and 20.5 ± 5.5 s, respectively. The overall tourniquet success rates in three successive study phases were 69.6%, 82.4% and 91.2%, respectively. A negative significant relationship was found between extremity circumference and tourniquet success. The results show that the efficacy of CAT application increases with training. Further studies are required to investigate the reasons underlying application failures. This single group prospective randomised study involves level of evidence 4.

    The purpose of this study was to determine whether premedication with ibuprofen or meloxicam increases the success rate of anaesthesia in teeth with irreversible pulpitis. In this parallel, double-blind clinical trial, 92 patients diagnosed with irreversible pulpitis were randomly divided into four groups of 23 patients. The first group (the no-premedication group) received no premedication, the second group (the meloxicam group) received 7.5 mg of meloxicam, the third group (the ibuprofen group) received 600 mg of ibuprofen, and the fourth group (the placebo group) received placebo 1 hour before intervention. Before taking the medication, electrical pulp testing (EPT) and the Heft-Parker visual analogue scale (VAS) were used to evaluate sensitivity and pain at baseline. Then, local anaesthesia was injected, and after 15 minutes, EPT was used again to evaluate tooth sensitivity. The pain during access preparation was also recorded using the Heft-Parker VAS. Ninety-two patients were analysed. The success rates of local anaesthesia were 21.7%, 34.8%, 78.3% and 73.9% in the no-premedication, placebo, ibuprofen and meloxicam groups, respectively, according to the EPT values. Considering the Heft-Parker VAS values, no premedication gave a 21.7% success rate, placebo gave a 34.8% success rate, ibuprofen gave an 82.6% success rate and meloxicam gave a 65.2% success rate.

The variables maternal age, maternal weight, body mass index, previous cesarean delivery, gestational age, parity, amount of amniotic fluid, placental location, and type of breech were studied using logistic regression analysis. The success rate of ECV was 52.2% (n=261). The variables significantly associated with success were parity, placental location, amount of amniotic fluid, and type of breech (Pbreech presentation had a 2.77-times higher success rate compared with a frank breech presentation (95% CI, 1.16-6.62). The area under the ROC curve showed a predictive ability of 73.6% (95% CI, 69.2%-77.9%) for these 3 variables. Parity, placental location, amount of amniotic fluid, and type of breech presentation were associated with the success rate of ECV.

    Objectives To determine if measures of successful-aging are associated with sexual activity, satisfaction, and function in older post-menopausal women. Design Cross-sectional study using self-report surveys; analyses include chi-square and t-tests and multiple linear regression analyses. Setting Community-dwelling older post-menopausal women in the greater San Diego Region. Participants 1,235 community-dwelling women aged 60-89 years participating at the San Diego site of the Women's Health Initiative. Measurements Demographics and self-report measures of sexual activity, function, and satisfaction and successful aging. Results Sexual activity and functioning (desire, arousal, vaginal tightness, use of lubricants, and ability to climax) were negatively associated with age, as were physical and mental health. In contrast, sexual satisfaction and self-rated successful aging and quality of life remained unchanged across age groups. Successful aging measures were positively associated with sexual measures, especially self-rated quality of life and sexual satisfaction. Conclusions Self-rated successful aging, quality of life, and sexual satisfaction appear to be stable in the face of declines in physical health, some cognitive abilities, and sexual activity and function and are positively associated with each other across ages 60-89 years.

  20. Human disturbance influences reproductive success and growth rate in California sea lions (Zalophus californianus.

    Directory of Open Access Journals (Sweden)

    Susannah S French

    Full Text Available The environment is currently undergoing changes at both global (e.g., climate change and local (e.g., tourism, pollution, habitat modification scales that have the capacity to affect the viability of animal and plant populations. Many of these changes, such as human disturbance, have an anthropogenic origin and therefore may be mitigated by management action. To do so requires an understanding of the impact of human activities and changing environmental conditions on population dynamics. We investigated the influence of human activity on important life history parameters (reproductive rate, and body condition, and growth rate of neonate pups for California sea lions (Zalophus californianus in the Gulf of California, Mexico. Increased human presence was associated with lower reproductive rates, which translated into reduced long-term population growth rates and suggested that human activities are a disturbance that could lead to population declines. We also observed higher body growth rates in pups with increased exposure to humans. Increased growth rates in pups may reflect a density dependent response to declining reproductive rates (e.g., decreased competition for resources. Our results highlight the potentially complex changes in life history parameters that may result from human disturbance, and their implication for population dynamics. We recommend careful monitoring of human activities in the Gulf of California and emphasize the importance of management strategies that explicitly consider the potential impact of human activities such as ecotourism on vertebrate populations.

    Magnetic resonance (MR) elastography allows the noninvasive assessment of liver stiffness, which is a surrogate for fibrosis. The purpose of this study was to describe our experience using liver MR elastography in a large pediatric population with attention to the frequency and causes of exam failure. Imaging records were searched for patients ≤18 years of age who underwent 2-D gradient recalled echo (GRE) MR elastography of the liver between September 2011 and August 2015 on one of two 1.5-T MRI platforms. Imaging reports and clinical records were reviewed for failed MR elastography acquisitions, factor(s) resulting in failure and whether a subsequent successful examination had been performed. Four hundred sixty-eight MR elastography examinations were performed in 372 patients between 1.5 months and 18 years of age during the study period. Ninety-six percent (450/468) of the examinations were successful. There was no significant difference in mean age (12.6±3.6 vs. 11.2±4.1 years, P=0.12) or body mass index (BMI) (28.2±12.4 vs. 29.5±10 kg/m{sup 2}, P=0.6) between patients with and without successful examinations. MR elastography failures were due to poor paddle positioning resulting in inadequate generation of hepatic shear waves (n=5), iron overload (n=4), patient inability to tolerate MRI (n=3), patient breathing/motion (n=3), artifact from implanted hardware (n=1) and technical malfunction (n=2). Seven of nine (78%) repeat examinations were successful (78%). Hepatic 2-D GRE MR elastography at 1.5 T is technically robust in children. Exam failure is infrequent and largely reflects patient specific factors, some of which can be mitigated with careful technique. (orig.)

    Understanding factors driving successful invasions is one of the cornerstones of invasion biology. Bird invasions have been frequently used as study models, and the foundation of current knowledge largely relies on species purposefully introduced during the 19th and early 20th centuries in countries colonized by Europeans. However, the profile of exotic bird species has changed radically in the last decades, as birds are now mostly introduced into the invasion process through unplanned releases from the worldwide pet and avicultural trade. Here we assessed the role of the three main drivers of invasion success (i.e., event-, species-, and location-level factors) on the establishment and spatial spread of exotic birds using an unprecedented dataset recorded throughout the last 100 y in the Iberian Peninsula. Our multimodel inference phylogenetic approach showed that the barriers that need to be overcome by a species to successfully establish or spread are not the same. Whereas establishment is largely related to event-level factors, apparently stochastic features of the introduction (time since first introduction and propagule pressure) and to the origin of introduced species (wild-caught species show higher invasiveness than captive-bred ones), the spread across the invaded region seems to be determined by the extent to which climatic conditions in the new region resemble those of the species' native range. Overall, these results contrast with what we learned from successful deliberate introductions and highlight that different management interventions should apply at different invasion stages, the most efficient strategies being related to event-level factors.

    Our objective was to compare the effect of two pain relief methods (remifentanil vs. nitrous oxide) on the success rate of external cephalic version. We conducted a randomized open label parallel-group controlled single-center clinical trial with sequential design, at Cruces University Hospital, Spain. Singleton pregnancies in noncephalic presentation at term that were referred for external cephalic version were assigned according to a balanced (1:1) restricted randomization scheme to analgesic treatment with remifentanil or nitrous oxide during the procedure. The primary endpoint was external cephalic version success rate. Secondary endpoints were adverse event rate, degree of pain, cesarean rate and perinatal outcomes. The trial was stopped early after the second interim analysis due to a very low likelihood of finding substantial differences in efficacy (futility). The external cephalic version success rate was the same in the two arms (31/60, 51.7%) with 120 women recruited, 60 in each arm. The mean pain score was significantly lower in the remifentanil group (3.2 ± 2.4 vs. 6.0 ± 2.3; p external cephalic version-related complications. There was a trend toward a higher frequency of adverse effects in the remifentanil group (18.3% vs. 6.7%, p = 0.10), with a significantly higher incidence rate (21.7 events/100 women vs. 6.7 events/100 women with nitrous oxide, p = 0.03). All reported adverse events were mild and reversible. Remifentanil for analgesia decreased external cephalic version-related pain but did not increase the success rate of external cephalic version at term and appeared to be associated with an increased frequency of mild adverse effects. © 2016 Nordic Federation of Societies of Obstetrics and Gynecology.

  4. RATING AS A TOOL FOR MEASURING SUCCESS: “PRO” AND “CONTRA”

    Directory of Open Access Journals (Sweden)

    M. V. Yurasova

    2017-01-01

    Full Text Available Modern style of management requires different mechanisms of evaluation. They are very important, the quality measurements of both the social processes and the social management. The measurement process requires the creation of different approaches and techniques. In the modern social management integrated indicators become of the great importance. They are calculated and sounded like ratings and indexes. They are applied to a wide variety of objects – countries, governors, companies, schools, neighborhoods, etс. Often, they determined the prestige and position of an object in a competitive environment. The article examines in detail the positive and negative aspects of building ratings and indexes. The author argues that in modern society emerges the belief in their universal applicability and objectivity. In the majority of ratings are included not only the objective (statistical or similar figures, but also subjective expert assessments. Many other elements in the methodology of ratings and indexes do not allow to say that they always reflect the real situation. Their main advantage is that they enable to select the best and the worst, and it is fundamentally important for a manager at any level. The process of total “menegerization” determines the popularity of indexes, as they form the basis of efficiency criteria. And it’s the focus on managerial efficiency, that, in fact, dictates the need for continuous assessment of the situation. The author reveals the problems that lie behind the construction of the ratings, and their subsequent use: assessing the quality of the primary data, the equivalence of experts work, etc. Any rating causes a certain reaction: argumentation for and against, discussions about the optimality of the selected parameters and methodology. In the article various approaches and methods of index construction are examined. There are examples of the most interesting ratings and indexes creating by different

    The incidence of caesarean section for breech presentation has increased markedly in the last 20 years. A prospective, interventional cohort study was carried out of the success rate of external cephalic version (ECV) and its predictors of as well as its impact on the rate of caesarean section for vaginal breech delivery. All 128 women admitted during the study period to the obstetrics department of a tertiary care military hospital in Taif, Saudi Arabia with breech presentation at term, regardless of age and parity, who accepted ECV were recruited. ECV was successful in 53.9% of the women. Most of the women with successful ECV delivered normally (84.1%) and only 14.5% of them delivered by caesarean section. Conversely, normal vaginal delivery was reported among 8.5% of those who had spontaneous version with failed ECV and approximately two-thirds of them delivered by caesarean section (62.7%). Successful ECV reduced the breech and caesarean section rate.

    Many factors influence the chance of having a baby with assisted reproductive technologies (ART). A 2016 Australian Competition and Consumer Commission (ACCC) investigation concluded that ART clinics needed to improve the quality of information they provide about chance of ART success. To evaluate changes in the quality of information about success rates provided on the websites of ART clinics in Australia and New Zealand before and after the ACCC investigation. Desktop audits of websites of ART clinics in Australia and New Zealand were conducted in 2016 and 2017 and available information about success rates was scored using a matrix with eight variables and a possible range of scores of 0-9. Of the 54 clinic websites identified in 2016, 32 had unique information and were eligible to be audited. Of these, 29 were also eligible to be audited in 2017. While there was a slight improvement in the mean score from 2016 to 2017 (4.93-5.28), this was not statistically significantly different. Of the 29 clinics, 14 had the same score on both occasions, 10 had a higher and five a lower information quality score in 2017. To allow people who consider ART to make informed decisions about treatment they need comprehensive and accurate information about what treatment entails and what the likely outcomes are. As measured by a scoring matrix, most ART clinics had not improved the quality of the information about success rates following the ACCC investigation. © 2017 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Aim: Effect of radiosynovectomy (RS) should be evaluated both by subjective and objective parameters in patients with osteoarthritis and in patients with inflammatory joint disorders not caused by rheumatoid arthritis. Methods: A total of 98 joints in 61 patients were investigated. Patients were divided into two groups. The first group included 35 patients with therapy-resistant effusions caused by severe osteoarthritis (46 joints). The second group consisted of 26 patients (52 joints) with ankylosing spondylitis, reactive arthritis, undifferentiated spondylarthropathy, psoriatic arthritis, pigmented villo-nodular synovitis, and recurrent synovitis following surgery. Effect of RS was evaluated by a standardized questionnaire and quantified by T/B-ratios derived from blood pool images prior to and after RS. Results: Within the first patient group suffering from osteoarthritis, 40% showed a good or excellent improvement of clinical symptoms, 51% were unchanged, and in 9% symptoms worsened. Similar results were found in the second patient group. The majority of unchanged results were small finger joints. In contrast, wrist and knee joints showed a better improvement. Good correlation between results of bone scan and patients subjective impression was found in 38% and 67% in the first and the second patient group, respectively. Conclusion: Radiosynovectomy might be an effective treatment in osteoarthritis and inflammatory joint disorders not caused by rheumatoid arthritis. (orig.)

    Full text: The aim of this study was to compare three radiopharmaceuticals for sentinel lymph node detection in breast cancer and malignant melanoma patients. We examined 100 women and 2 men with breast cancer (average age 59.3 years) and 167 patients with malignant melanoma (69 men with mean age of 58.6 years and 98 women with mean age of 53.6 years). Lymphoscintigraphy was performed in all patients after injection of the radiotracer, either of the three: NANOCIS (average particle size 100 nm), SENTISCINT (particle size 100-600 nm), and NANOCOLL (particle size under 80 nm). Dynamic scintigraphy was performed in melanoma patients while breast cancer patients were subjected to stating imaging at 1-2 and 22 hours of injection. In patients with melanoma surgery was done on the same day, to remove the primary tumor, sentinel lymph node and other nodes, wherever required. In breast cancer patients, surgery, more or less, was done on the second day of radiotracer injection. In operation theatre isosulfan blue dye and gamma probe was used to detect sentinel lymph nodes. In breast cancer patients, scintigraphy detected a total of 231 lymph nodes but failed to show sentinel lymph node in 7 patients (success rate of lymphoscintigraphy 93.1 %). Using gamma probe 158 lymph nodes were detected in 89 patients but sentinel nodes were missed in 9 patients (success rate of probe was 89.9 %). 146 lymph nodes could be visualised using blue dye in 92 patients but were missed in 12 patients (detection rate by dye was 87 %). In 2 patients sentinel lymph node could not be detected by any method. In patients with melanoma, scintigraphy showed 304 lymph nodes. However, it did not detect sentinel lymph node in 9 patients (success rate of lymphoscintigraphy was 94.6 %). 104 patients were examined by means of gamma probe and 132 lymph nodes were detected and no lymph node was found in 13 patients (success rate of probe 87.5%). Using blue dye in 140 patients, 131 nodes were found but were

    To evaluate predictors of the success rate for one session of shock wave lithotripsy (SWL), focusing on the relationships between pretreatment hydronephrosis grade and one-session SWL success rates. The medical records of 1824 consecutive patients who underwent an initial session of SWL for treatment of urinary stones between 2005 and 2013 were reviewed. After exclusion, 700 patients with a single, 4-20 mm diameter radiopaque calculus were included in the study. The mean maximal stone length (MSL) and skin-to-stone distance were 9.2±3.9 and 110.8±18.9 mm, respectively. The average values for mean stone density (MSD) and stone heterogeneity index (SHI) were 707.0±272.1 and 244.9±110.1, respectively. One-session success rates were 68.4, 75.0, 75.1, 54.0, and 10.5% in patients with hydronephrosis grade 0, 1, 2, 3, and 4, respectively. Patients were classified into success or failure groups based on SWL outcome. Multivariate logistic regression analyses revealed that MSL [odds ratio (OR) 0.888, 95% confidence intervals (CI): 0.841-0.934, phydronephrosis grade (OR 0.601, 95% CI: 0.368-0.988, p=0.043) were significantly associated with one-session success. Pretreatment grades 3 or 4 hydronephrosis were associated with failure of SWL in patients with a single ureteral stone. In the presence of severe hydronephrosis, especially hydronephrosis grade 4; physicians should proceed cautiously in choosing and offering SWL as the primary treatment for ureteral stone. © Copyright: Yonsei University College of Medicine 2017

    Full Text Available The objective of this retrospective study was to assess the success rate of Forssell’s modified myectomy – surgical treatment of crib biting on 33 horses of various breeds identified as stereotypical cribbers which were referred to the Equine Clinic in Brno between January 2001 and December 2010. The long term outcome was available for all horses. The overall success of the surgery without considering influencing factors was 61%. Thirteen horses (39% returned to the stereotypical behaviour sooner or later after the surgery. In this retrospective study we confirmed the dependence of success of the surgery on the necessity of early treatment of the problem (up to 6 months after the appearance of initial signs, with the significance level of P = 0.037. Any connection between age, breed or sex, and positive outcome of the surgery were not confirmed during statistical evaluation. When the horses were diagnosed early enough, an 80% success rate in surgical treatment performed within 6 months from the initial signs of crib biting was recorded, which seems to be very promising. It can be concluded that surgical treatment of crib biting by modified Forsell’s myectomy is the recommended option in the therapy of this oral stereotype.

    Placement of a transobturator midurethral sling (MUS) is the standard surgical treatment for stress urinary incontinence. Most recent MUS procedures have been poorly evaluated. We compared the results using a "new" device expected to reduce postoperative pain, the TVT ABBREVO® system (TVT-Abb), with those using the TVT™ obturator system (TVT-O). This was a retrospective study comparing the use of the TVT-Abb (in 50 patients) and the TVT-O (in 50 patients). The main outcomes were the amount of postoperative pain, the success rate (no reported urinary leakage and negative cough test) with both MUS procedures, and the prevalence of complications. The mean follow-up time was 12 months. The preoperative characteristics of the two groups were comparable. There was less postoperative pain (VAS, 0 to 100) in the TVT-Abb group than in the TVT-O group (12.2 vs. 24.4, p TVT-Abb group and the TVT-O group (8 % vs. 12 %, p = 0.74). The prevalences of perioperative and postoperative complications (bladder/urethral injury, haemorrhage) in the two groups were equal. The success rates were similar at 12 months after surgery (88 % vs. 78 %, p = 0.29). The success rates with TVT-Abb and TVT-O were equal at 12 months after surgery, but there was less immediate postoperative pain with TVT-Abb.

    External dacryocystorhinostomy (DCR) is the method of choice to treat nasolacrimal duct (NLD) obstruction and the other approaches are compared with it, with a failure rate of 4% to 13%. The current study aimed to assess the causes of failure in external DCR by postoperative endoscopic and pathological evaluation. The current retrospective cross sectional study followed-up113 patients with external DCR and silicone intubation for three months. Silicone tubes were removed after the third months. Failure was confirmed based on the clinical findings and irrigation test. Paranasal sinus computed tomography (CT) scanning, and endoscopic and pathological evaluations were performed in the failed cases. Totally, 113 patients underwent external DCR. The patients included 71 females and 42 males. The mean age of the patients was 55.91 years; ranged from 18 to 86. Epiphora was the most common complaint before surgery (90.3%). Clinically, epiphora continued in 17 cases (15%), of which 94.11% had at least one sinus CT abnormality and 82.35% had at least one endoscopic abnormality. The most common endoscopic findings were deviated septum (70.6%), scar tissue (52.94%), concha bullosa (46.9%), septal adhesion (47.05%), enlarged middle turbinate (41.2%), and sump syndrome (11.7%). The failure was significantly associated with the chronicity of the initial symptoms (P-value=0.00). Pathologically, there were significant relationship amongst the failure rate, scar formation, and allergic rhinitis (P-values =0.00 and <0.05, respectively). Preoperative endonasal evaluation and consultation with an otolaryngologist can improve surgical outcomes and help to have a better conscious to intranasal abnormalities before external DCR surgery.

    To estimate whether the use of regional anesthesia is associated with increased success of external cephalic version. We searched MEDLINE, EMBASE, the Cochrane Library, and clinical trial registries. Electronic databases were searched from 1966 through April 2011 for published, randomized controlled trials in the English language comparing regional anesthesia with no regional anesthesia for external cephalic version. The primary outcome was external cephalic version success. Secondary outcomes included cesarean delivery, maternal discomfort, and adverse events. Pooled risk ratios (relative risk) were calculated using a random-effects model. Heterogeneity was assessed using the Cochran's Q statistic and quantified using the I Z method. Six randomized controlled trials met criteria for study inclusion. Regional anesthesia was associated with a higher external cephalic version success rate compared with intravenous or no analgesia (59.7% compared with 37.6%; pooled relative risk 1.58; 95% confidence interval [CI] 1.29-1.93). This significant association persisted when the data were stratified by type of regional anesthesia (spinal compared with epidural). The number needed to treat with regional anesthesia to achieve one additional successful external cephalic version was five. There was no evidence of statistical heterogeneity (P=.32, I Z=14.9%) or publication bias (Harbord test P=.78). There was no statistically significant difference in the risk of cesarean delivery comparing regional anesthesia with intravenous or no analgesia (48.4% compared with 59.3%; pooled relative risk 0.80; 95% CI 0.55-1.17). Adverse events were rare and not significantly different between the two groups. Regional anesthesia is associated with a higher success rate of external cephalic version.

    In order to develop a method for estimating the success/failure rates of reproductive processes, especially those of ovulation and neonate nurturing, in the Japanese black bear (Ursus thibetanus japonicus), we examined offspring status, corpora lutea (CLs), placental scars (PSs) and corpora albicantia (CAs) in 159 females (0-23 years old) killed as nuisances on Honshu Island of Japan during 2001-2009. PSs were found to remain in the uterus at least until November of the year of parturition. CA detectability began to decline after September of the year of parturition. Monthly and age-specific proportions of CL-present females revealed that the post-mating season starts in August, and that the age of first ovulation is 4 years. These results indicate that the success rate of ovulation (SRO: the probability that solitary/non-lactating mature females actually succeed in ovulation) can be estimated by calculating the proportion of CL-present females among > or = 4-year-old females without PSs captured from August to November; the early litter loss rate (ELLR: the probability that parenting females lose all of their cubs [0-year-old offspring] before mating season) can be estimated by calculating the proportion of CL-present females among those with PSs and CAs captured in August or later. The estimated values of SRO and ELLR were 0.93 (62/67) and 0.27 (6/22), respectively.

    Identification of some somatic molecular alterations in non-small-cell lung cancer (NSCLC) has become evidence-based practice. The success and failure rate of using commercially available tumor genotyping techniques in routine day-to-day NSCLC pathology samples is not well described. We sought to evaluate the success and failure rate of EGFR mutation, KRAS mutation, and ALK FISH in a cohort of lung cancers subjected to routine clinical tumor genotype. Clinicopathologic data, tumor genotype success and failure rates were retrospectively compiled and analyzed from 381 patient-tumor samples. From these 381 patients with lung cancer, the mean age was 65 years, 61.2% were women, 75.9% were white, 27.8% were never smokers, 73.8% had advanced NSCLC and 86.1% had adenocarcinoma histology. The tumor tissue was obtained from surgical specimens in 48.8%, core needle biopsies in 17.9%, and as cell blocks from aspirates or fluid in 33.3% of cases. Anatomic sites for tissue collection included lung (49.3%), lymph nodes (22.3%), pleura (11.8%), bone (6.0%), brain (6.0%), among others. The overall success rate for EGFR mutation analysis was 94.2%, for KRAS mutation 91.6% and for ALK FISH 91.6%. The highest failure rates were observed when the tissue was obtained from image-guided percutaneous transthoracic core-needle biopsies (31.8%, 27.3%, and 35.3% for EGFR, KRAS, and ALK tests, respectively) and bone specimens (23.1%, 15.4%, and 23.1%, respectively). In specimens obtained from bone, the failure rates were significantly higher for biopsies than resection specimens (40% vs. 0%, p=0.024 for EGFR) and for decalcified compared to non-decalcified samples (60% vs. 5.5%, p=0.021 for EGFR). Tumor genotype techniques are feasible in most samples, outside small image-guided percutaneous transthoracic core-needle biopsies and bone samples from core biopsies with decalcification, and therefore expansion of routine tumor genotype into the care of patients with NSCLC may not require special

  19. Omics in Reproductive Medicine: Application of Novel Technologies to Improve the IVF Success Rate.

    Science.gov (United States)

    Nerenz, R D

    Treatment for many infertile couples often consists of in vitro fertilization (IVF) but an estimated 70% of IVF cycles fail to produce a live birth. In an attempt to improve the live birth rate, the vast majority of IVF cycles performed in the United States involve the transfer of multiple embryos, a practice that increases the risk of multiple gestation pregnancy. This is a concern because multiple gestation pregnancies are associated with an increased incidence of maternal and fetal complications and significant cost associated with the care of preterm infants. As the ideal outcome of each IVF cycle is the birth of a single healthy baby, significant effort has focused on identifying embryos with the greatest developmental potential. To date, selection of euploid embryos using comprehensive chromosome screening (CCS) is the most promising approach while metabolomic and proteomic assessment of spent culture medium have the potential to noninvasively assess embryo viability. Endometrial gene expression profiling may help determine the optimal time to perform embryo transfer. While CCS has been implemented in some clinics, further development and optimization will be required before analysis of spent culture medium and endometrial gene expression profiling make the transition to clinical use. This review will describe efforts to identify embryos with the greatest potential to result in a healthy, live birth, with a particular emphasis on detection of embryo aneuploidy and metabolic profiling of spent embryo culture medium. Assessment of endometrial receptivity to identify the optimal time to perform embryo transfer will also be discussed. © 2016 Elsevier Inc. All rights reserved.

    The goal of this study was to evaluate the outcome of Tension-free Vaginal Tape Obturator (TVT-O) operation in the treatment of urodynamic stress incontinence (USI) in obese females, with respect to uroflowmetric changes, success rate and postoperative complications. This prospective observational study included 26 patients with USI at the Obstetrics & Gynecology department-Cairo University hospital during the year 2015. The participants had body mass index (BMI)≥30. Patients underwent TVT-O operation. Follow up of the patients was performed by cough test and uroflowmetry after one week, one month, three months and six months. Postoperative complications such as groin pain, sense of incomplete emptying, need to strain to complete micturition and urinary tract infection were recorded. Comparisons between groups were done using Chi square, Phi-Cramer test for categorical variables. The mean age for the subjects was 43.58±9.01years. The mean BMI was 33.4±2.1. The success rate of TVT-O operation was 21 out of 26 patients (≈81%). Normal maximum flow rate was in 88% of patients at week one and was normal in 100% of patients at months three and six (p=0.101 & 0.101). Postoperative groin pain was the main complaint during the first week after operation and decreased significantly from week one to the 1st month postoperative (84.62% & 65.38%, P=0.041). TVT-O operation showed a high success rate in treatment of USI in obese patients without affecting the voiding function of the bladder as proven by the uroflowmetry. The main postoperative complaint was the groin pain which significantly improved after one month. Copyright © 2017 Elsevier B.V. All rights reserved.

    The aim of this study was to identify factors associated with the results of smoking cessation attempts. Data were collected in Clermont-Ferrand from a smoking cessation clinic between 1999 and 2009 (1,361 patients). Smoking cessation was considered a success when patients were abstinent 6 months after the beginning of cessation. Multivariate logistic regression was used to investigate the association between abstinence and different factors. The significant factors were a history of depression (ORadjusted = 0.57, p = 0.003), state of depression at the initial consultation (ORa = 0.64, p = 0.005), other psychoactive substances (ORa = 0.52, psuccess was four times higher). A high score in the Richmond test had a greater impact on success with increasing age (significant interaction: p = 0.01). In exclusive smokers, the contemplation level in the Prochaska algorithm was enough to obtain a satisfactory abstinence rate (65.5%) whereas among consumers of other psychoactive substances, it was necessary to reach the preparation level in the Prochaska algorithm to achieve a success rate greater than 50% (significant interaction: p = 0.02). The psychological preparation of the smoker plays a critical role. The management of smoking cessation must be personalized, especially for consumers of other psychoactive substances and/or smokers with a history of depression.

  2. Investigating Strategies to Increase Persistence and Success Rates among Anatomy & Physiology Students: A Case Study at Austin Community College District

    Vedartham, Padmaja B.

    Community colleges train 60% of healthcare workers nationwide. Human anatomy and physiology (A&P) courses are considered prerequisite courses for all students who aspire to enter health-related programs. The attrition rates for A&P students at community colleges nationally are close to 50%. Community colleges with open-door policies admit nontraditional students who have historically been educationally and economically disadvantaged and are labeled at risk. At-risk students offer a challenge to the colleges and in particular to allied health programs with their mathematical and science oriented requirements. This case study was designed to determine the strategies used to increase the success rates and retention rates among A&P students at Austin Community College District (ACC) in Texas. Data show that ACC has almost 100% retention and higher success rates among A&P students as compared to other colleges. Qualitative data were collected from eight full-time faculty, three administrators, three administrative staff, one director, and two advisors. The findings linked both academic and nonacademic variables to high retention and success rates. The key strategies that helped the A&P students to overcome the challenges to persist and succeed were an assessment test, two preparatory biology courses, technology, and teaching strategies. Taking an assessment test before being permitted to access the class helped students prepare themselves for the rigors of A&P. These strategies provided the students with the foundation of knowledge in the basic biological principles and processes, study skills, and time management skills that would prepare them for the material presented in A&P courses and later in the allied health programs. The principle themes identified in this research--namely requiring students to take the assessment test, providing materials (BIOL.1308, CE4000, and online modules) to prepare students for taking the test, a $2 million grant awarded by the

    Implants were first designed to be used in the reconstruction of edentulous mandibles. However, with the technological advancement, enormous changes were made to improve the implant design and surface characteristics leading to the wide use of implants in the replacement of missing teeth. During the transition from an edentulous span to a fixed prosthesis, narrow body implants (NBIs) have been proposed to enhance patient comfort and function. Therefore, this study was aimed at investigating the survival and success rates of NBIs used for supporting immediately nonfunctional loaded provisional fixed partial denture (PFPD). Either 2.2- or 2.4-mm-diameter dental implants were placed transmucosally into the edentulous ridges of 10 partially edentulous patients. PFPD of self-cured bis-acryl composite material were made using either a vacuform template chairside or a relined prefabricated PFPD. Occlusal adjustments were made to ensure that there was no functional loading on the provisional restorations before they were secured onto the transitional implants. At 1 year, the implant success and survival rates were 38.7% and 93.5%, respectively, with a mean percentage of bone loss of 9.46% (0%-40%) and a mean bone loss of 1.19 mm (range: 0-3.5 mm). With a favorable implant survival rate, the use of NBIs to support provisional restorations seemed to be a feasible treatment option. In addition, there is merit for research on the long-term use of NBIs-supported final prostheses.

    We hypothesized that cooling hyperbaric bupivacaine from 23 to 5 °C may limit the intrathecal spread of bupivacaine and therefore increase the success rate of unilateral spinal anesthesia and decrease the rate of hemodynamic complications. A hundred patients scheduled for elective unilateral inguinal hernia surgery were randomly allocated to receive 1.8 ml of 0.5 % hyperbaric bupivacaine intrathecally at either 5 °C (group I, n = 50) or at 23 °C (group II, n = 50). Following spinal block at the L2-3 interspace, the lateral decubitus position was maintained for 15 min. Unilateral spinal anesthesia was assessed and confirmed at 15 and 30 min. The levels of sensory and motor block on the operative side were evaluated until complete resolution. The rate of unilateral spinal anesthesia at 15 and 30 min was significantly higher in group I (p = 0.015 and 0.028, respectively). Hypotensive events and bradycardia were significantly rarer in group I (p = 0.014 and 0.037, respectively). The density and viscosity of the solution at 5 °C was significantly higher than at 23 °C (p < 0.0001). Compared with group II, sensory block peaked later in group I (17.4 vs 12.6 min) and at a lower level (T9 vs T7), and two-segment regression of sensory block (76.4 vs 84.3 min) and motor block recovery was shorter (157.6 vs 193.4 min) (p < 0.0001). Cooling of hyperbaric bupivacaine to 5 °C increased the density and viscosity of the solution and the success rate of unilateral spinal anesthesia, and decreased the hemodynamic complication rate.

    To determine success rates, predictors of recurrence, and recurrence management of patients treated for short anterior urethral strictures by direct vision internal urethrotomy (DVIU). We identified 128 patients who underwent DVIU of the anterior urethra between December 2009 and March 2016. Follow-up was conducted by telephone interviews. Success rates were assessed by Kaplan-Meier estimators. Predictors of stricture recurrence and different further therapy strategies were identified by uni- and multivariable Cox regression analyses. The mean age was 63.8 years (standard deviation: 16.3) and the overall success rate was 51.6% (N = 66) at a median follow-up of 16 months (interquartile range: 6-43). Median time to stricture recurrence was six months (interquartile range: 2-12). In uni- and multivariable analyses, only repeat DVIU (hazard ratio [HR] = 1.87, 95% confidence interval (CI) = 1.13-3.11, P= .015; and HR=1.78, 95% CI = 1.05-3.03, P = .032, respectively) was a risk factor for recurrence. Of 62 patients with recurrence, 35.5% underwent urethroplasty, 29% underwent further endoscopic treatment, and 33.9% did not undergo further interventional therapy. Age (HR = 1.05, 95% CI = 1.01-1.09, P = .019) and diabetes (HR = 2.90, 95% CI = 1.02-8.26, P = .047) were predictors of no further interventional therapy. DVIU seems justifiable in short urethral strictures as a primary treatment. Prior DVIU was a risk factor for recurrence. In case of recurrence, about one-third of the patients did not undergo any further therapy. Higher age and diabetes predicted the denial of any further treatment. Copyright © 2017 Elsevier Inc.

    Prosthetic joint infection (PJI) is a leading cause of early revision after total knee arthroplasty (TKA). Open debridement with exchange of tibial insert allows treatment of infection with retention of fixed components. We investigated the success rate of this procedure in the treatment of knee PJIs in a nationwide material, and determined whether the results were affected by microbiology, antibiotic treatment, or timing of debridement. 145 primary TKAs revised for the first time, due to infection, with debridement and exchange of the tibial insert were identified in the Swedish Knee Arthroplasty Register (SKAR). Staphylococcus aureus was the most common pathogen (37%) followed by coagulase-negative staphylococci (CNS) (23%). Failure was defined as death before the end of antibiotic treatment, revision of major components due to infection, life-long antibiotic treatment, or chronic infection. The overall healing rate was 75%. The type of infecting pathogen did not statistically significantly affect outcome. Staphylococcal infections treated without a combination of antibiotics including rifampin had a higher failure rate than those treated with rifampin (RR = 4, 95% CI: 2-10). In the 16 cases with more than 3 weeks of symptoms before treatment, the healing rate was 62%, as compared to 77% in the other cases (p = 0.2). The few patients with a revision model of prosthesis at primary operation had a high failure rate (5 of 8). Good results can be achieved by open debridement with exchange of tibial insert. It is important to use an antibiotic combination including rifampin in staphylococcal infections.

    Deciduous forests of the eastern US are broadly approaching an ecological threshold in which early successional dominant trees are senescing and giving way to later successional species, with unknown consequences for regional carbon (C) cycling. Though recent research demonstrates that forests may accumulate C for centuries, the mechanisms behind sustained rates of C storage in old, particularly deciduous, forests have not been identified. In a regionally representative forest at the University of Michigan Biological Station, we are combining observational and experimental C cycling studies to forecast how forest C storage responds to climate variation, disturbance, and succession. The Forest Accelerated Succession ExperimenT (FASET), in which >6,700 aspen and birch trees (~35 % LAI) were stem girdled within a 39 ha area, is testing the hypothesis that forest production will increase rather than decline with age, due to increases in nitrogen (N) availability, N allocation to the canopy, and the concurrent development of a more biologically and structurally complex canopy. Results thus far support our hypothesis that aging forests in the region may sustain high rates of C storage through shifts in N cycling and increased canopy complexity. Girdling-induced mortality of early successional species reduced soil respiration, accelerated fine root turnover, and prompted the redistribution of N from the foliage of early to later successional species. Nitrogen redistribution increased leaf area index (LAI) production by later successional species, offsetting declines in LAI from senescing early successional species. High rates of net primary production (NPP) were sustained in stands comprising a diverse assemblage of early and later successional species because later successional species, when already present in the canopy, rapidly compensated for declining growth of early successional species. Canopy structural complexity, which increased with forest age, was positively

    2017-01-12

    To establish how medically assisted reproduction (MAR) clinics report success rates on their websites. Websites of private and NHS clinics offering in vitro fertilisation (IVF) in the UK. We identified clinics offering IVF using the Choose a Fertility Clinic facility on the website of the Human Fertilisation and Embryology Authority (HFEA). Of 81 clinics identified, a website could not be found for 2, leaving 79 for inclusion in the analysis. Outcome measures reported by clinic websites. The numerator and denominator included in the outcome measure were of interest. 53 (67%) websites reported their performance using 51 different outcome measures. It was most common to report pregnancy (83% of these clinics) or live birth rates (51%). 31 different ways of reporting pregnancy and 9 different ways of reporting live birth were identified. 11 (21%) reported multiple birth or pregnancy rates. 1 clinic provided information on adverse events. It was usual for clinics to present results without relevant contextual information such as sample size, reporting period, the characteristics of patients and particular details of treatments. Many combinations of numerator and denominator are available for the purpose of reporting success rates for MAR. The range of reporting options available to clinics is further increased by the possibility of presenting results for subgroups of patients and for different time periods. Given the status of these websites as advertisements to patients, the risk of selective reporting is considerable. Binding guidance is required to ensure consistent, informative reporting.

    To systematically review previous studies and to assess, via a subgroup meta-analysis, the combined odds ratio (OR) of prognostic factors affecting the success of miniscrew implants (MIs) inserted into the buccal posterior region. Three electronic searches that were limited to articles on clinical human studies using MIs that were published in English prior to March 2015 were conducted. The outcome measure was the success of MIs. Patient factors included age, sex, and jaw of insertion (maxilla vs. mandible), while the MI factors included length and diameter. A meta-analysis was performed on 17 individual studies. The quality of each study was assessed for non-randomized studies and quantified using the Newcastle-Ottawa Scale. The meta-analysis outcome was a combined OR. Subgroup and sensitivity analyses based on the study design, study quality, and sample size of miniscrews implanted were performed. Significantly higher success rates were revealed for MIs inserted in the maxilla, for patients ≥ 20 years of age, and for long MIs (≥ 8 mm) and MIs with a large diameter (> 1.4 mm). All subgroups acquired homogeneity, and the combined OR of the prospective studies (OR, 3.67; 95% confidence interval [CI], 2.10-6.44) was significantly higher in the maxilla than that in the retrospective studies (OR, 2.10; 95% CI, 1.60-2.74). When a treatment plan is made, these risk factors, i.e. jaw of insertion, age, MI length, and MI diameter, should be taken into account, while sex is not critical to the success of MIs.

    Infection with Helicobacter pylori is highly prevalent worldwide, especially in developing countries. Its presence in the gastroduodenal mucosa is related with development of peptic ulcer and other illnesses. The eradication of H. pylori improves mucosal histology in patients with peptic ulcers. This study was aimed to verify if H. pylori recurrence occurs five years or more after confirmed eradication in patients with peptic ulcer. Moreover, we sought to determine the recurrence rate. Retrospective and longitudinal, this study was based on a sample of 201 patients from western Paraná, Brazil. The patients were diagnosed with peptic ulcer disease, in the period of 1990-2000, and followed for five years or more after successful H. pylori eradication. Patients with early recurrence - prior to five years after eradication - were excluded from the sample. During an average follow-up of 8 years, 180 patients (89.55%) remained negative, and 21 (10.45%) became positive for H. pylori infection. New ulcers appeared in two-thirds of the patients with H. pylori recurrence. The recurrence of H. pylori in patients with peptic ulcer can occur in the long-term - even if the infection had been successfully eradicated and the patients had remained free of recurrence in the first years of follow-up.

    Despite the benefits of the minimally invasive endoscopic treatment for vesicoureteral reflux (VUR) it has a major drawback which is low success rate in high grade VUR. For overcoming this problem, we introduce a new modified technique of endoscopic treatment called periureteral injection technique (PIT). In a prospective study a total of 37 ureters in 19 boys and 14 girls were treated, including 3 bilateral cases. Of 37 units, 30 (81.1%) had grade IV and 7 (18.9%) had grade V primary VUR (18 right, 13 left and 3 bilateral units). Subureteral injection of Vantris(®) was done at the 5-o'clock and 7-o'clock positions in which the direction of injecting needles were almost parallel. Pre- and post-operative evaluation included urinalysis, urinary tract ultrasonography, voiding cystourethrography (VCUG), dimercaptosuccinic acid scan and urodynamic studies. The median age was 38 months (range 8-125). At 6 months follow up period confirmed with VCUG, the VUR has been disappeared in 34 (91.8%) units and 3 units [2 (5.4%) grade II and 1 (2.7%) had grade III)] had downgraded VUR. Complications included early fever due to urinary tract infection in 1 children, transient dysuria in 2 patients and low back pain in one patient (Summary Table). The success rate of PIT for treatment of high grade VUR is high. However, further studies with more patients and longer follow up periods are needed to draw final conclusion.

    The induced membrane technique was designed by Masquelet et al. to address segmental bone defects of critical size in adults. It has been used after bone defects of traumatic, infectious and tumoral origin with satisfactory results. Recently, it has been used in children but, after an initial enthusiasm, several cases of failure have been reported. The purpose of this study was to assess the success rate and the risk factors of failure of the induced membrane for children. We conducted a systematic review of all the studies reporting the results of the induced membrane technique to address bone defects of critical size in children. Our primary outcome was the success rate of the technique defined as a bone union before any iterative surgery. Our secondary outcomes were the complications and the risk factors of failure. We searched Medline via Pubmed, EMBASE and the Cochrane Library. Twelve studies, including 69 patients, met the inclusion criteria. There were 41 boys and 28 girls. Mean age at surgery was 10 years. Mean size of resection was 12.38 cm and the mean time between the two stages was 5.86 months. Mean rate of bone union after the two stages of the induced membrane technique was 58% (40/69) but this rate increased to 87% after revision surgeries (60/69). Main complications were non-unions (19/69), lysis of the graft (6/69) and fractures of the bone graft (6/69). Only 1/69 deep infection was reported. Other non specific complications were regularly reported such limb length discrepancies, joint stiffness and protruding wires. Risk factor of failure that could be suspected comprised the resection of a malignant tumour, a bone defect located at the femur, a wide resection, a long time between the two stages, an unstable osteosynthesis and a bone graft associating autograft to other graft materials. The induced membrane technique is suitable for bone defects of critical size in children. It is a reliable technique with no need of micro vascular surgery

    Small and Medium Enterprises (SMEs) are business activities that can expand the level of employment rate and provide economic services to the wider community and can play a role in the process of equalizing and improving people’s income, stimulating economic growth as well as realizing national stabilities. The aim of this study is to identify the factors of the success rate for Small and Medium Enterprises (SMEs) in furniture manufacturing sector in Klaten regency, Central Java, Indonesia. The method employed in this study was descriptive qualitative by also employing quantitative analysis of which the data were collected through observations, interviews and by administering questionnaires. The results seemed to indicate that the furniture business in Klaten is still experiencing difficulties in managing its various aspects of business, namely in terms of marketing (either directly or indirectly or by making the best use media of technology) and managing capital. All this time, the SMEs in furniture manufacturing sector in Klaten have been utilizing a very simple system in producing tables, chairs, wardrobes and any other furniture products which are then distributed to be sold by larger furniture companies. This condition makes the SMEs unable to be independent in running their business.

    Full Text Available This paper addresses the exam success rates in Mathematics 1 at the College of Polytechnics in Jihlava (CPJ. Primary data taken from the school information system cover the years 2006–2015. We carried out a success rate analysis based on several criteria (form of study, the reason for termination of studies, gender. We observed the dependence of the success rate on the aforementioned criteria and time. Plus a detailed analysis of the success rate with respect to the study programme was conducted. The contingency tables analysis and correspondence analysis were used to assess the dependencies. The research showed that the success rate in Mathematics 1 has been decreasing over the course of the monitored period of time. The success rate of full-time students is higher compared to the part-time students. Women have higher success rate than men. The respective study programmes showed equivalent results. Technical study programmes show lower success rate in mathematics. The research furthermore implies that mathematics may not always be the cause of a complete termination of studies. To reverse the trend of the growing failure rate we introduced an entrance test of high school basic mathematics followed by a course for those who fail at this test. As a part of our currently running project, our school have been innovating the e-learning modules and working on the textbooks for Seminar in Mathematics that may be completed in a form of an intensive summer or winter school in mathematics. This project’s objective is an overall improvement of students’ mathematical knowledge and skills.

    This exploratory study examined novice intubators and the effect difficult airway factors have on pre- and posttraining oral-tracheal simulation intubation success rates. Using a two-level, full-factorial design of experimentation (DOE) involving a combination of six airway factors (curved vs. straight laryngoscope blade, trismus, tongue edema, laryngeal spasm, pharyngeal obstruction, or cervical immobilization), 64 airway scenarios were prospectively randomized to 12 critical care nurses to evaluate pre- and posttraining first-pass intubation success rates on a simulator. Scenario variables and intubation outcomes were analyzed using a generalized linear mixed-effects model to determine two-way main and interactive effects. Interactive effects between the six study factors were nonsignificant (p = 0.69). For both pre- and posttraining, main effects showed the straight blade (p = 0.006), tongue edema (p = 0.0001), and laryngeal spasm (p = 0.004) significantly reduced success rates, while trismus (p = 0.358), pharyngeal obstruction (p = 0.078), and cervical immobilization did not significantly change the success rate. First-pass intubation success rate on the simulator significantly improved (p = 0.005) from pre- (19%) to posttraining (36%). Design of experimentation is useful in analyzing the effect difficult airway factors and training have on simulator intubation success rates. Future quality improvement DOE simulator research studies should be performed to help clarify the relationship between simulator factors and patient intubation rates.

    The discovery of Dehalococcoides mccartyi reducing perchloroethene and trichloroethene (TCE) to ethene was a key landmark for bioremediation applications at contaminated sites. D. mccartyi-containing cultures are typically grown in batch-fed reactors. On the other hand, continuous cultivation of these microorganisms has been described only at long hydraulic retention times (HRTs). We report the cultivation of a representative D. mccartyi-containing culture in continuous stirred-tank reactors (CSTRs) at a short, 3-d HRT, using TCE as the electron acceptor. We successfully operated 3-d HRT CSTRs for up to 120 days and observed sustained dechlorination of TCE at influent concentrations of 1 and 2 mM TCE to ≥ 97 % ethene, coupled to the production of 10(12) D. mccartyi cells Lculture (-1). These outcomes were possible in part by using a medium with low bicarbonate concentrations (5 mM) to minimize the excessive proliferation of microorganisms that use bicarbonate as an electron acceptor and compete with D. mccartyi for H2. The maximum conversion rates for the CSTR-produced culture were 0.13 ± 0.016, 0.06 ± 0.018, and 0.02 ± 0.007 mmol Cl(-) Lculture (-1) h(-1), respectively, for TCE, cis-dichloroethene, and vinyl chloride. The CSTR operation described here provides the fastest laboratory cultivation rate of high-cell density Dehalococcoides cultures reported in the literature to date. This cultivation method provides a fundamental scientific platform for potential future operations of such a system at larger scales.

    In Germany, rates of primary total knee arthroplasty procedures and exchange arthroplasty procedures continue to rise. Late-onset peri-prosthetic infection constitutes a serious complication whose management may be dependent upon the spectrum of micro-organisms involved. The aim of this study was to provide a retrospective analysis of the effectiveness of initial eradication measures performed as part of a two-stage procedure. Between 2002 and 2008, a total of 328 patients who had received a first-time diagnosis of chronic peri-prosthetic knee infection following total knee arthroplasty (TKA) subsequently underwent surgery at our clinic. The surgical approach consisted of a two-stage procedure, with the initial procedure consisting of the removal of the prosthesis and radical debridement, followed by insertion of an antibiotic-loaded static spacer. The effectiveness of the procedure was assessed after six weeks, with each patient undergoing a number of clinical and laboratory-based tests, including knee joint aspiration. Staphylococcus aureus strains were responsible for 68% (n=223) of the total number of cases of peri-prosthetic knee infection. 19% of cases (n=62) showed evidence of gram-negative bacteria, while MRSA accounted for 15% (n=49) of cases. Six weeks after completion of the above-named treatment regimen, eradication of infection was considered successful in 289 patients (88.1%). Eradication was unsuccessful in 22% of MRSA infections (n=11) and 7% of MSSA infections (n=23). The treatment regimen outlined in this report is capable of achieving satisfactory results in the management of late-onset peri-prosthetic knee infection, with one exception: patients with infections caused by MRSA showed high failure rates.

    Full Text Available The present research aimed at investigating the effect of communication channels on the economic success of early profitable and entrepreneur small and medium enterprises in the agricultural sector. It was an applied research in which the descriptive-survey method was used. The research sample included 356 founders of entrepreneur small and medium enterprises (at the time of conducting the research in the Markazi province, Iran, among which 100 founders were selected according to the Cochran formulation using the stratified random sampling method. A questionnaire was used as the research tool and its validity was confirmed as the face validity by a group of teachers and experts. The questionnaire’s reliability was calculated using Cronbach’s alpha (α = 0.82. The results indicated that the information seeking facilities of most of the entrepreneurs were seen at a good level (53 persons, 53% and acquiring information from other businesses and consulting contacts with the neighbors and relatives, product sellers and promoting factors were listed as the highest priorities of the respondents, respectively. Also, there was a meaningful relationship between rate of using information and communication resources with the variables namely age, duration of operation on the job, number of people operating the business and number using loans. The results of regression analysis indicated that seven communication channels, promoters, other producers, product sellers, group visit, training films, creditors, radio and TV in the order of significance have defined 78.4% of the dependent variable changes.

    HNF1A gene mutations are the most common cause of maturity-onset diabetes of the young (MODY) in the UK. Persons with HNF1A-MODY display sensitivity to sulphonylurea therapy; however, the long-term efficacy is not established. There is limited literature as to the prevalence of micro- and macrovascular complications in this unique cohort. The aim of this study was to determine the natural progression and clinical management of HNF1A-MODY diabetes in a dedicated MODY clinic. Sixty patients with HNF1A-MODY and a cohort of 60 BMI-, age-, ethnicity- and diabetes duration-matched patients with Type 1 diabetes mellitus participated in the study. All patients were phenotyped in detail. Clinical follow-up of the HNF1A-MODY cohort occurred on a bi-annual basis. Following a genetic diagnosis of MODY, the majority of the cohort treated with sulphonylurea therapy remained insulin independent at 84-month follow-up (80%). The HbA1c in the HNF1A-MODY group treated with sulphonylurea therapy alone improved significantly over the study period [from 49 (44-63) mmol/mol, 6.6 (6.2-7.9)% to 41 (31-50) mmol/mol, 5.9 (5-6.7)%; P = 0.003]. The rate of retinopathy was significantly lower than that noted in the Type 1 diabetes mellitus group (13.6 vs. 50%; P = 0.0001).There was also a lower rate of microalbuminuria and cardiovascular disease in the HNF1A-MODY group compared with the Type 1 diabetes mellitus group. This study demonstrates that the majority of patients with HNF1A-MODY can be maintained successfully on sulphonylurea therapy with good glycaemic control. We note a significantly lower rate of micro- and macrovascular complications than reported previously. The use of appropriate therapy at early stages of the disorder may decrease the incidence of complications. © 2015 Diabetes UK.

    To decrease the risk of recurrence or metastasis in differentiated thyroid cancer (DTC), selected patients receive radioactive iodine ablation of remnant thyroid tissue or tumor. A low iodine diet can enhance uptake of radioactive iodine. We compared the success rates of radioactive iodine ablation therapy in patients who followed two different low iodine diets (LIDs). The success rates of postsurgical radioactive iodine ablation in DTC patients receiving empiric doses of 150 mCi were retrospectively reviewed. First-time radioactive iodine ablation therapy was done in 71 patients following less strict LID. Less strict LID restricted seafood, iodized salt, egg yolk, dairy products, processed meat, instant prepared meals, and multivitamins. Very strict LID additionally restricted rice, freshwater fish, spinach, and soybean products. Radioactive iodine ablation therapy was considered successful when follow up {sup 123I} whole body scan was negative and stimulated serum thyroglobulin level was less than 2.0 ng/mL. The success rate of patients following less strict LID was 80.3% and for very strict LID 75.6%. There was no statistically significant difference in the success rates between the two LID groups (P=0.48). Very strict LID may not contribute to improving the success rate of initial radioactive iodine ablation therapy at the cost of great inconvenience to the patient.

    One of the ways to improve the quality of services in the health system is through clinical governance. This method aims to create a framework for clinical services providers to be accountable in return for continuing improvement of quality and maintaining standards of services. To evaluate the success rate of clinical governance implementation in Kerman teaching hospitals based on 9 steps of Karsh's Model. This cross-sectional study was conducted in 2015 on 94 people including chief executive officers (CEOs), nursing managers, clinical governance managers and experts, head nurses and nurses. The required data were collected through a researcher-made questionnaire containing 38 questions with three-point Likert Scale (good, moderate, and weak). The Karsh's Model consists of nine steps including top management commitment to change, accountability for change, creating a structured approach for change, training, pilot implementation, communication, feedback, simulation, and end-user participation. Data analysis using descriptive statistics and Mann-Whitney-Wilcoxon test was done by SPSS software version 16. About 81.9 % of respondents were female and 74.5 have a Bachelor of Nursing (BN) degree. In general, the status of clinical governance implementation in studied hospitals based on 9 steps of the model was 44 % (moderate). A significant relationship was observed among accountability and organizational position (p=0.0012) and field of study (p=0.000). Also, there were significant relationships between structure-based approach and organizational position (p=0.007), communication and demographic characteristics (p=0.000), and end-user participation with organizational position (p=0.03). Clinical governance should be implemented by correct needs assessment and participation of all stakeholders, to ensure its enforcement in practice, and to enhance the quality of services.

    About 35 percent of Nigeria's population of the more than 180 M relies on groundwater. Due to the lack of an adequate water supply system within Ogun State, many homes result to drilling their own private wells. Most groundwater is sourced from shallow wells (less than 30 m) and is often of poor water quality. The number of borehole failures is also alarming. Several entrepreneurs have seized on the lack of adequate water supply to drill for groundwater. Several of these wells have either failed or are not adequate for the purposed use of the water. There also appears to be no proper coordination of the citing of these wells. To increase the success rates of the boreholes, the use of geophysical methods amongst others is recommended. This study examines the exploration for groundwater and water quality in Ogun State in Nigeria, using Ota as an example. Ogun State has both significant surface and groundwater resources. However, due to the indiscriminate and lack of proper waste disposal, the vast majority of the surface waters and shallow well waters are impaired making them unsuitable for many users. To access a deeper groundwater source, a geophysical survey was performed to assist in finding a possible location for a borehole. A geophysical survey using the vertical electric sounding (VES) with Schlumberger configuration was carried out. The data shows that there are five layers within the proposed borehole site. Based on the data, it was suggested that a well be placed at a depth between 65-75 m (213-246 ft.). The borehole was drilled to 67m. This depth, from the literature, corresponds to the Abeokuta formation. A pump was installed at 66 m (217 ft.) depth and the first 50 feet of the borehole was grouted to prevent surface water from getting into the hole. A pumping test was performed for about two hours. While this was noteworthy, the data is not made available to any centralized body. No water chemistry was undertaken and more still needs to be done with

    To investigate the technical success rate and procedure-related complications of computed tomography (CT)-guided needle biopsy of lung lesions and to identify the factors that are correlated with the occurrence of procedure-related complications. This was a single- institution retrospective study of 867 consecutive CT-guided needle biopsies of lung lesions performed on 772 patients in a tertiary cancer centre. The technical success rate and complications were correlated with patient, lung lesion, and procedure-related variables. The technical success rate was 87.2% and the mortality rate was 0.12%. Of the 867 total biopsies 25.7% were associated with pneumothorax, and 6.5% required chest tube drainage. The haemothorax rate was 1.8%. There was positive correlation between the development of pneumothorax and smaller lesion diameter (ptechnical success and a low rate of major complications. The present study has revealed several variables that can be used to identify high-risk procedures. A post-procedural chest X-ray within hours after the procedure is highly recommended to identify high-risk patients who require chest tube placement.

    Background: The treatment results of symptomatic radiation therapy of the Eustachian tube in chronic otitis media had to be evaluated retrospectively. Patients and Methods: Between 1980 and 1997, 66 patients were referred for therapy. The median age was 58 years. In the clinical presentation, all the patients had a hearing impairment, 35 patients complained of pain, 21 had otorrhea. In their history, 20 patients indicated chronic recurrent infections. The complaints lasted for 4.7 years in the median, primary conservative (adstringentia, antibiotics) and surgical treatment (paracentesis, tympanic tubule, tympanoplastic) did not lead to lasting cure. In 40 of 66 patients, finally radiation therapy was done of both Eustachian tubes. With opposed fields and cobalt-60 photons a total dose of 6 Gy at single doses of 1 Gy, three times a week, was applied. Under the causes for exclusion of radiation therapy were non-acceptance of the patients (nine), prior radiation therapies (six) or spontaneous improvement after initial presentation in our department. The treatment results were evaluated by interviews of the patients and regular otorhinolaryngological examinations. Results: There were no side effects noticed. 28 of 40 (70%) patients reported a significant improvement that could be verified by objective otorhinolaryngological examinations. In the group of 26 nonirradiated patients, 22 could be interviewed indicating in 16 cases (72%) that the complaints were unchanged and chronic otitis media was lasting. In a subgroup analysis concerning the duration of otitis media radiation therapy proved more effective in an acute and subacute stadium of disease of up to 5 years duration, while the patients resistant to radiation therapy were entirely in a chronic stage of disease exceeding 5 years duration.

    During spine surgery, the spinal cord is electrophysiologically monitored via transcranial electrical stimulation of motor-evoked potentials (TES-MEPs) to prevent injury. Transcranial electrical stimulation of motor-evoked potential involves the use of either constant-current or constant-voltage stimulation; however, there are few comparative data available regarding their ability to adequately elicit compound motor action potentials. We hypothesized that the success rates of TES-MEP recordings would be similar between constant-current and constant-voltage stimulations in patients undergoing spine surgery. The objective of this study was to compare the success rates of TES-MEP recordings between constant-current and constant-voltage stimulation. This is a prospective, within-subject study. Data from 100 patients undergoing spinal surgery at the cervical, thoracic, or lumbar level were analyzed. The success rates of the TES-MEP recordings from each muscle were examined. Transcranial electrical stimulation with constant-current and constant-voltage stimulations at the C3 and C4 electrode positions (international "10-20" system) was applied to each patient. Compound muscle action potentials were bilaterally recorded from the abductor pollicis brevis (APB), deltoid (Del), abductor hallucis (AH), tibialis anterior (TA), gastrocnemius (GC), and quadriceps (Quad) muscles. The success rates of the TES-MEP recordings from the right Del, right APB, bilateral Quad, right TA, right GC, and bilateral AH muscles were significantly higher using constant-voltage stimulation than those using constant-current stimulation. The overall success rates with constant-voltage and constant-current stimulations were 86.3% and 68.8%, respectively (risk ratio 1.25 [95% confidence interval: 1.20-1.31]). The success rates of TES-MEP recordings were higher using constant-voltage stimulation compared with constant-current stimulation in patients undergoing spinal surgery. Copyright © 2017

    Both the self-drilling and self-tapping miniscrews have been commonly used as anchorage reinforcement devices in orthodontic treatment. The aim of this study was to compare the success rates of self-drilling and self-tapping miniscrews in orthodontic practice. Literature searches were performed by electronic search in database including PubMed, Embase, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure and SIGLE, and manual search of relevant journals and reference lists of included studies. Randomized controlled trials, clinical controlled trials and cohort studies comparing the success rates of self-drilling and self-tapping miniscrews as orthodontic anchorage. The data of success rates and root contact rates were extracted by two investigators independently. After evaluating the risk of bias, the odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. Subgroup analysis was performed on the basis of study design, follow-ups, participant ages and immediate/delayed loading. Sensitivity analysis was performed to test the stability of the results in meta-analysis. Six studies assessed as high quality were included in the meta-analysis. The meta-analysis results showed no difference between the two types of screws in the success rates. The root contact rates of the two screws were similar, while self-drilling miniscrews displayed higher risk of failure when contacting with a tooth root. Currently available clinical evidence suggests that the success rates of self-tapping and self-drilling miniscrews are similar. Determination of the position and direction of placement should be more precise when self-drilling miniscrews are used in sites with narrow root proximity. None. None. © The Author 2016.

    To investigate the efficacy of 0.2 mL vs. 0.6 mL of 2% lidocaine when given as a supplementary intraligamentary injection after a failed inferior alveolar nerve block (IANB). Ninety-seven adult patients with symptomatic irreversible pulpits received an IANB and root canal treatment was initiated. Pain during treatment was recorded using a visual analogue scale (Heft-Parker VAS). Patients with unsuccessful anaesthesia (n = 78) randomly received intraligamentary injection of either 0.2 mL or 0.6 mL of 2% lidocaine with 1 : 80 000 epinephrine. Root canal treatment was reinitiated. Success after primary injection or supplementary injection was defined as no or mild pain (HP VAS score ≤54 mm) during access preparation and root canal instrumentation. Heart rate was monitored using a finger pulse oximeter. The anaesthetic success rates were analysed with Pearson chi-square test at 5% significance levels. The heart rate changes were analysed using t-tests. The intraligamentary injections with 0.2 mL solution gave an anaesthetic success rate of 64%, whilst the 0.6 mL was successful in 84% of cases with failed primary IANB. (χ 2  = 4.3, P = 0.03). There was no significant effect of the volume of intraligamentary injection on the change in heart rate. Increasing the volume of intraligamentary injection improved the success rates after a failed primary anaesthetic injection. © 2017 International Endodontic Journal.

    To analyse the impact of external cephalic version (ECV) on caesarean section rate in a team with a high success rate of vaginal delivery in breech presentation. Retrospective monocentric study including 298 patients with a breech presentations between 33 and 35weeks of amenorrhea followed at our university hospital and delivered after 35weeks, between 1st January 2011 and 31st December 2013. Patients were divided into 2 groups: planned ECV (n=216 patients) versus no planned ECV (n=57 patients). Our rate of successful vaginal breech delivery over the period of the study was 61.1%. We performed 165 ECV, with a 21.8% success rate. The average term of the attempt of ECV was 36.7weeks of amenorrhea. The caesarean section rate was not significantly different in the planned ECV group, even after adjustment on age, parity and previous caesarean delivery (adjusted OR=1.67 [0.77-3.61]). Attempt of ECV did not reduce the number of breech presentation at delivery (61.1% versus 61.4% [P=0.55]). Planned ECV in our center with a high level of breech vaginal delivery did not significantly impact our cesarean section rate. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    The preferential citation of studies with the highest success rates could exaggerate perceived effectiveness, particularly for treatments with widely varying published success rates such as radiofrequency catheter ablation for atrial fibrillation. We systematically identified observational studies and clinical trials of radiofrequency catheter ablation of atrial fibrillation between 1990 and 2012. Generalized Poisson regression was used to estimate association between study success rate and total citation count, adjusting for sample size, journal impact factor, time since publication, study design, and whether first or last author was a consensus-defined pre-eminent expert. We identified 174 articles meeting our inclusion criteria (36 289 subjects). After adjustment only for time since publication, a 10-point increase above the mean in pooled reported success rates was associated with a 17.8% increase in citation count at 5 years postpublication (95% confidence interval, 7.1-28.4%; Pcitation count; 95% confidence interval, 7.6-29.6%; Pcitation count, which may indicate citation bias. To readers of the literature, radiofrequency catheter ablation of atrial fibrillation could be perceived to be more effective than the data supports. These findings may have implications for a wide variety of novel cardiovascular therapies. © 2014 American Heart Association, Inc.

    Ocean acidification may have far-reaching consequences for marine community and ecosystem dynamics, but its full impacts remain poorly understood due to the difficulty of manipulating pCO 2 at the ecosystem level to mimic realistic fluctuations that occur on a number of different timescales. It is especially unclear how quickly communities at various stages of development respond to intermediate-scale pCO 2 change and, if high pCO 2 is relieved mid-succession, whether past acidification effects persist, are reversed by alleviation of pCO 2 stress, or are worsened by departures from prior high pCO 2 conditions to which organisms had acclimatized. Here, we used reciprocal transplant experiments along a shallow water volcanic pCO 2 gradient to assess the importance of the timing and duration of high pCO 2 exposure (i.e., discrete events at different stages of successional development vs. continuous exposure) on patterns of colonization and succession in a benthic fouling community. We show that succession at the acidified site was initially delayed (less community change by 8 weeks) but then caught up over the next 4 weeks. These changes in succession led to homogenization of communities maintained in or transplanted to acidified conditions, and altered community structure in ways that reflected both short- and longer-term acidification history. These community shifts are likely a result of interspecific variability in response to increased pCO 2 and changes in species interactions. High pCO 2 altered biofilm development, allowing serpulids to do best at the acidified site by the end of the experiment, although early (pretransplant) negative effects of pCO 2 on recruitment of these worms were still detectable. The ascidians Diplosoma sp. and Botryllus sp. settled later and were more tolerant to acidification. Overall, transient and persistent acidification-driven changes in the biofouling community, via both past and more recent exposure, could have important

    Full Text Available Objective: Objective: To compare the success rate between the one session and two session indirect pulp capping of asymptomatic pulpitis for 1 year after the treatment was performed in children with different caries risk. Material and Methods: The children and the teeth were selected according to certain criteria for inclusion in the study. According to that, 72 children with low, moderate and high caries risk were included and 131 teeth with asymptomatic pulpitis were treated. The clinical protocols for indirect pulp capping (IPC in one session and two sessions were defined. The review appointments were performed 6 and 12 months after the treatment using certain clinical and radiographic criteria which defined success or post-treatment complications. The results are statistically analysed using One Sided Exact Two-Proportion Test with 95% Significance level (5% risk of type I error. Results: The statistical test showed that between the compared success rates of the one session and two sessions IPC, on the 6th and 12th month, there wasn’t a significant difference (p>0.05. This was valid for every one of the examined groups of patients (p>0. 05. This proves that there is no difference in the success rates of treatment of pulpitis in primary teeth using one or two sessions. Conclusions: The results about the success of treatment of asymptomatic pulpitis in primary teeth during one or two sessions have confirmed the results showed in other current studies. Our study has confirmed (clinically and radiographically the success of both techniques and we have concluded that in children with high caries risk, more appropriate technique is the one performed in two sessions. Treatment in one session is recommended in children with low or moderate caries risk.

    The aim of this study was to compare 2 kinds of anti-inflammatory medicines (ie, dexamethasone and ibuprofen) with a placebo according to their effects on the success rates of an inferior alveolar nerve block (IANB) for the endodontic treatment of mandibular molars with irreversible pulpitis. A total of 165 patients were divided into 3 groups of 55 patients each and were given a capsule of the same color and size (ie, a placebo of lactose powder, 400 mg ibuprofen, or 0.5 mg dexamethasone). One hour after the oral administration of the capsules, all the patients received a standard IANB. In patients with a successful IANB, the teeth were examined with a cold pulp test. Patients were asked to assess their pain using the visual analog scale. Then, endodontic access cavity preparation was initiated. In case of pain during the treatment, the patients were asked to rate the pain on the visual analog scale. Success was defined as no or mild pain during treatment. The chi-square test and analysis of variance were used to compare qualitative and quantitative data among the groups. No significant differences were found regarding the sex of the patients in the 3 groups (P > .05). The dexamethasone group showed significantly higher success rates compared with the placebo group (P = .001). There were no significant differences between the ibuprofen and placebo groups (P = .055) or the dexamethasone and ibuprofen groups (P = .34). Premedication with dexamethasone increased the success rate of an IANB in mandibular molars with asymptomatic irreversible pulpitis. Copyright © 2013 American Association of Endodontists.

    To evaluate the effect of listening to music on pain, anxiety, and success of procedure during office-based percutaneous nephrostomy tube placement (PNTP). One hundred consecutive patients (age >18 years) with hydronephrosis were prospectively enrolled in this study. All patients were prospectively randomized to undergo office-based PNTP with (Group I, n = 50) or without music (Group II, n = 50). Anxiety levels were evaluated with State Trait Anxiety Inventory. A visual analog scale was used to evaluate pain levels, patient's satisfaction, and willingness to undergo the procedure. We also compared success rates of procedures. The mean age, duration of procedure, and gender distribution were statistically similar between the two groups. The mean postprocedural heart rates and systolic blood pressures in Group I patients were significantly lower than Group II patients (p = 0.01 and p = 0.028, respectively), whereas preprocedural pulse rate and systolic blood pressure were similar. The mean anxiety level and mean pain score of Group I were significantly lower than those of Group II (p = 0.008 and p music during office-based PNTP decreases anxiety or pain and increases success rate of procedure. As an alternative to sedation or general anesthesia, music is easily accessible without side effect and cost.

    Full Text Available The objectives of this study were to determine the relationship among game performance, injury rate, and practice exposure in a professional male basketball team. A retroospective analysis of prospective collected data was conducted over seven consecutive seasons (2007/2008 to 2013/2014. Data collection included sports performance during competition (statistical evaluation, injury rate, and total exposure (games and practices. Over the surveillance period, 162 injuries (91 practice; 71 matches occurred over 32,668 hours of exposure (556 games and 2005 practices. There was a strong positive correlation between: 1 exposure (total number of practices and hours of exposure and the total number of injuries (r = 0.77; p = 0.04; 2 exposure (total hours of exposure and total hours of practice exposure and performance (total team ranking (r = 0.77 and p = 0.04, and r = 0.8 and p = 0.03, respectively; and 3 total number of injuries and performance (total team ranking (r = 0.84; p = 0.02. While increasing practice and competition time is related to greater team performance, it also increases the number of injuries. However, higher injury rates were not associated with worse overall team performance. Efforts to reduce high-risk activity during practice, optimally replaced with injury prevention training, might help to reduce injury risk.

    3D and multi-planar reconstruction of CT images have become indispensable in the routine practice of diagnostic imaging. These tools cannot only enhance our ability to diagnose diseases, but can also assist in therapeutic planning as well. The technology utilized to create these can also render surface reconstructions, which may have the undesired potential of providing sufficient detail to allow recognition of facial features and consequently patient identity, leading to violation of patient privacy rights as described in the HIPAA (Health Insurance Portability and Accountability Act) legislation. The purpose of this study is to evaluate whether 3D reconstructed images of a patient's facial features can indeed be used to reliably or confidently identify that specific patient. Surface reconstructed images of the study participants were created used as candidates for matching with digital photographs of participants. Data analysis was performed to determine the ability of observers to successfully match 3D surface reconstructed images of the face with facial photographs. The amount of time required to perform the match was recorded as well. We also plan to investigate the ability of digital masks or physical drapes to conceal patient identity. The recently expressed concerns over the inability to truly "anonymize" CT (and MRI) studies of the head/face/brain are yet to be tested in a prospective study. We believe that it is important to establish whether these reconstructed images are a "threat" to patient privacy/security and if so, whether minimal interventions from a clinical perspective can substantially reduce this possibility.

    Full Text Available Objectives Achieving adequate anesthesia with inferior alveolar nerve blocks (IANB is of great importance during dental procedures. The aim of the present study was to assess the success rate of two anesthetic agents (bupivacaine and lidocaine for IANB when treating teeth with irreversible pulpitis. Materials and Methods Sixty volunteer male and female patients who required root canal treatment of a mandibular molar due to caries participated in the present study. The inclusion criteria included prolonged pain to thermal stimulus but no spontaneous pain. The patients were randomly allocated to receive either 2% lidocaine with 1:80,000 epinephrine or 0.5% bupivacaine with 1:200,000 epinephrine as an IANB injection. The sensitivity of the teeth to a cold test as well as the amount of pain during access cavity preparation and root canal instrumentation were recorded. Results were statistically analyzed with the Chi-Square and Fischer's exact tests. Results At the final step, fifty-nine patients were included in the study. The success rate for bupivacaine and lidocaine groups were 20.0% and 24.1%, respectively. There was no significant difference between the two groups at any stage of the treatment procedure. Conclusions There was no difference in success rates of anesthesia when bupivacaine and lidocaine were used for IANB injections to treat mandibular molar teeth with irreversible pulpitis. Neither agent was able to completely anesthetize the teeth effectively. Therefore, practitioners should be prepared to administer supplemental anesthesia to overcome pain during root canal treatment.

The patients were randomly allocated to receive either 2% lidocaine with 1:80,000 epinephrine or 0.5% bupivacaine with 1:200,000 epinephrine as an IANB injection. The sensitivity of the teeth to a cold test as well as the amount of pain during access cavity preparation and root canal instrumentation were recorded. Results were statistically analyzed with the Chi-Square and Fischer's exact tests. At the final step, fifty-nine patients were included in the study. The success rate for bupivacaine and lidocaine groups were 20.0% and 24.1%, respectively. There was no significant difference between the two groups at any stage of the treatment procedure. There was no difference in success rates of anesthesia when bupivacaine and lidocaine were used for IANB injections to treat mandibular molar teeth with irreversible pulpitis. Neither agent was able to completely anesthetize the teeth effectively. Therefore, practitioners should be prepared to administer supplemental anesthesia to overcome pain during root canal treatment.

    Full Text Available The replacement of conventional sample preparation techniques with newer techniques which are automated, faster and more eco-friendly, is nowadays desired in every analytical laboratory. One of the techniques with the attributes mentioned above is the Accelerated Solvent Extraction. In order to evaluate how successful this method is for the extraction of fat and organochlorine pesticides (OCPs from dried fish meat samples, we have tested two series of diverse fish using Dionex™ 350 ASE provided by Thermo Scientific™ (Germany. For a more interesting approach, we added to our investigation 7 polychlorinated biphenyl (PCBs, 3 thricholorobenzenes, 2 tetrachlorobenzenes, 1 pentachlorobenzenes and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD. The study focused on comparing the recoveries of these analytes from different fish samples, after replacing the conventional reference method of the laboratory with ASE. The ASE parameters tested were previously used for the extraction of fat and polybrominated diphenyl ethers (PBDE from fish samples: temperature: 120 ° C; static time: 5 min; number of cycles: 3; flushing volume: 25%; rinse with nitrogen: 90 s; solvent: cyclohexane/ethyl acetate (ratio 1:1. The ASE method provided similar and in some cases better results when compared to the standard reference method, more rapidly, eco-friendly and safer. Any high or low recoveries of the analytes taken into study are attributed to random or systematic errors during the Clean-up step of the extracts and the quantification with Gas Chromatography coupled with Tandem Mass-Spectrometry (GC MS/MS.

    Abortion, spontaneous or induced, is a common complication of pregnancy and exploration of available and safe regimens for medical abortion in developing countries seems crucial. The present study was aimed to assess the effect of letrozole in combination with misoprostol in women eligible for legal therapeutic abortion with gestational age ≤14weeks. This clinical randomized trial was conducted on 78 women who were candidate of medical abortion and eligible for legal abortion with gestational age ≤14 weeks that were randomly divided into two groups of case and controls. Case group received daily oral dose of 10mg letrozole for three days followed by vaginal misoprostol. In control group the patients received only vaginal misoprostol. The rate of complete abortion, induction-of-abortion time, and side-effects were assessed. Complete abortion was observed in 30 patients (76.9%) in case group and 9 (23.1%) cases were failed. In control group there was 16 (41.03%) complete abortions and 23 (58.97%) cases were failed to abort. Patients with gestational age of between 6 and 10 weeks did not show significant difference in both groups (P=0.134). Regarding pregnancy remnants there were significant differences between two groups (P=0.034). The time form admission to discharge in case groups were significantly shorter than those in control group (P=0.001). The indication for curettage in case group was significantly less than control group (P=0.001). A 3-day course of letrozole (10mg/daily) followed by misoprostol was associated with a higher complete abortion and lower curettage rates and reduction in time from admission to discharge in women with gestational age ≤14 weeks compared to misoprostol alone.

    Over the past several years, non-operative management (NOM) has increasingly been recommended for the care of selected blunt abdominal solid organ injuries. No prospective study has evaluated the rate of NOM of blunt abdominal trauma in the northwest of Iran. The objective of our study was to evaluate the success rate of this kind of management in patients who do not require emergency surgery. This prospective study was carried out in Imam Khomeini Hospital (as a referral center of trauma) at Tabriz University of Medical Sciences, Iran, between 20 March 2004 and 20 March 2007. All trauma patients who had suffered an injury to a solid abdominal organ (kidney, liver, or spleen) were selected for initial analysis, using the Student's t test or the c2 test. During the three years of the study, 98 patients (83 males and 15 females) with blunt trauma were selected to NOM for renal, hepatic and splenic injuries. Mean age was 26.1+/-17.7 years (range, 2 to 89) and mean injury severity score (ISS) was 14.5+/-7.4. The success rate of NOM was 93.8%. Fifty-one patients (43 males, 8 females; mean ISS, 14.2+/-5.8) underwent NOM of splenic trauma; 38 patients (33 males, 5 females; mean ISS, 12.9+/-8.2) hepatic trauma, and nine patients (7 males, 2 females; mean ISS, 22.2+/-7.6) renal trauma. Six patients underwent laparotomy due to the failure of NOM. The success rates of this treatment were 94.1%, 94.7% and 88.8% for the spleen, liver and kidney injuries, respectively. Age, female gender and ISS were significant predictors of the failure of NOM (Ptrauma. The study indicates that the rates of NOM vary in relation to the severity of the organ injury. This suggests trauma centers should use this approach.

    Reliability of successful outcomes in men with erectile dysfunction (ED) on phosphodiesterase type 5 inhibitors is an important aspect of patient management. We examined reliability of successful outcomes in a large integrated dataset of randomized tadalafil trials. Success rates, time to success, subsequent success after first success, and probability of success were analyzed based on Sexual Encounter Profile questions 2 and 3. Data from 3,254 ED patients treated with tadalafil 10 mg (N = 510), 20 mg (N = 1,772), or placebo (N = 972) were pooled from 17 placebo-controlled studies. Tadalafil patients had significantly higher first-attempt success rates vs. placebo. This effect was consistent across most subgroups; however, patients with severe ED experienced a greater response to tadalafil than patients with mild-moderate ED. Approximately 80% of patients achieved successful penile insertion within two attempts with either tadalafil dose and successful intercourse within eight attempts for tadalafil 10 mg and four attempts for tadalafil 20 mg. However, approximately 70% of tadalafil-treated patients achieved successful intercourse even by the second attempt. Subsequent success rates were higher for patients with first-attempt success (81.5% for 10 mg and 86.1% for 20 mg vs. 66.2% for placebo, P success (53.2% for 10 mg and 56.4% for 20 mg vs. 39.9% for placebo, P success rates at early attempts were similar to rates at later attempts (i.e., attempts 5 and 10 vs. 25), although insertion success rates were significantly lower earlier in treatment. The findings affirm the reliability of successful outcomes with tadalafil treatment and that first-attempt success is a critical factor affecting subsequent outcomes. The results further show that even among men who did not succeed on first attempt, a substantial proportion will have successful outcomes if treatment is maintained. © 2012 International Society for Sexual Medicine.

    The economic implications of the choice of gonadotrophin influence decision making but their cost-effectiveness in frozen-embryo transfer cycles has not been adequately studied. An economic evaluation was performed comparing highly purified human menopausal gonadotrophin (HP-HMG) and recombinant FSH (rFSH) using individual patient data (n=986) from two large randomized controlled trials using a long agonist IVF protocol. The simulation model incorporated live birth data and published UK costs of IVF-related medical resources. After treatment for up-to-three cycles (one fresh and up to two subsequent fresh or frozen cycles conditional on availability of cryopreserved embryos), the cumulative live birth rate was 53.7% (95% CI 49.3-58.1%) for HP-HMG and 44.6% (40.2-49.0%) for rFSH (OR 1.44, 95% CI 1.12-1.85; Pcosts per IVF treatment for HP-HMG and rFSH were pound5393 ( pound5341-5449) and pound6269 ( pound6210-6324), respectively (number needed to treat to fund one additional treatment was seven; Pcosts applied, the median cost per IVF baby delivered with HP-HMG was pound11,157 ( pound11,089-11,129) and pound14,227 ( pound14,183-14,222) with rFSH (Pcost saving using HP-HMG remained after varying model parameters in a probabilistic sensitivity analysis. 2010 Reproductive Healthcare Ltd.

    Full Text Available Estimated glomerular filtration rate (eGFR is used for diagnosis of chronic kidney disease (CKD. The eGFR models based on serum creatinine or cystatin C are used more in clinical practice. Albuminuria and neck circumference are associated with CKD and may have correlations with eGFR.We explored the correlations and modelling formulates among various indicators such as serum creatinine, cystatin C, albuminuria, and neck circumference for eGFR.Cross-sectional study.We reviewed the records of patients with high cardiovascular risk from 2010 to 2011 in Taiwan. 24-hour urine creatinine clearance was used as the standard. We utilized a decision tree to select for variables and adopted a stepwise regression method to generate five models. Model 1 was based on only serum creatinine and was adjusted for age and gender. Model 2 added serum cystatin C, models 3 and 4 added albuminuria and neck circumference, respectively. Model 5 simultaneously added both albuminuria and neck circumference.Total 177 patients were recruited in this study. In model 1, the bias was 2.01 and its precision was 14.04. In model 2, the bias was reduced to 1.86 with a precision of 13.48. The bias of model 3 was 1.49 with a precision of 12.89, and the bias for model 4 was 1.74 with a precision of 12.97. In model 5, the bias could be lower to 1.40 with a precision of 12.53.In this study, the predicting ability of eGFR was improved after the addition of serum cystatin C compared to serum creatinine alone. The bias was more significantly reduced by the calculation of albuminuria. Furthermore, the model generated by combined albuminuria and neck circumference could provide the best eGFR predictions among these five eGFR models. Neck circumference can be investigated potentially in the further studies.

    To assess whether immunostimulatory cytosine-phosphate-guanine oligodeoxynucleotides (CpG-ODN) combined with interleukin-2 (IL-2) improves the number of mitotic metaphases and the detection rate of chromosomal abnormalities in chronic lymphocytic leukaemia (CLL). Bone marrow specimens were collected from 36 patients with CLL. CLL cells were cultured with CpG-ODN type DSP30 plus IL-2 for 72 h, following which R-banding analysis was conducted. Conventional culture without the immunostimulant served as the control group. The incidence of genetic abnormalities was measured by fluorescence in situ hybridisation (FISH) using a panel of five specific probes: D13S25 (13q14.3), RB1 (13q14), P53 (17p13), ATM (11q22.3) and CSP12 (trisomy 12, +12). In the control group, chromosome analysis achieved a success rate of only 22.2, and 11.1% of abnormal karyotypes were detected. After immunostimulation with DSP30 plus IL-2, chromosome analysis achieved a success rate of up to 91.6, and 41.6% of abnormal karyotypes were detected. FISH analysis detected 77.7% of abnormalities. FISH combined with CpG-ODN DSP30 plus IL-2 improved the detection rate of chromosomal abnormalities in CLL to 83.3%. CpG-ODN DSP30 combined with IL-2 is effective in improving the detection rate of chromosomal abnormalities in CLL cells. This combination with FISH analysis is conducive to increasing the detection rate of genetic abnormalities in CLL.

  3. One picture or a thousand words? Influence of question length and illustration support on the success and skip rates on online tests

    Full Text Available The growing popularity of automatically graded online tests, either as an evaluation or self-assessment tool in online or blended education, demands a review of how these questions are designed and delivered to their intended audience. This paper analyzes the results of over 20,000 pre-university mock online quizzes designed to train the students for the Spanish university admission test (known as “Pruebas de Acceso a la Universidad” or “Selectividad” in the technical drawing subject, corresponding to the June and September intakes of 2009 and 2015. The influence of two key aspects on the questions success and skip rates is assessed: (a the presence or absence of illustration support and (b the length of the question as a proxy of reading comprehension difficulty. The results support that the presence of an accompanying illustration in the questions result in fewer skipped questions and mode successful answers, while the length of the question has the opposite effect. The performance difference in the 6-year span is also discussed, showing a slight decline over time in the pass rates while the skip rates remain stable. When comparing both two intakes, corresponding to different academic profiles of students that passed the June exam and those who did not, the success ratio is unsurprisingly lower for the students in the second intake. These findings should help improving the design of online quizzes, including more visual content and/or rephrasing the questions to be more concise, to fit the requirements of students educated in a more visual environment of multimedia technologies.

    that once chronic venous leg ulcers were colonized (weeks or months preoperatively) by P. aeruginosa, the success rate of skin grafting deteriorated despite aggressive treatment. To investigate this, a retrospective study was performed on the clinical outcome of 82 consecutive patients with chronic venous...... regression analysis was carried out leaving P. aeruginosa as the only predictor left in the model (p¿=¿0.001). This study supports our hypothesis that P. aeruginosa in chronic venous leg ulcers, despite treatment, has considerable impact on partial take or rejection of split-thickness skin grafts....

    To evaluate whether sonographic (US) diagnosis of the fetal spine position could increase the success rate of manual rotation of the fetal occiput (MRFO) in second-stage arrest in persistent occiput posterior position (OPP). In this randomized controlled parallel single-center trial, 58 nulliparous in second-stage arrest of labor with fetus in cephalic presentation and OPP diagnosed by US were randomly assigned to group A where the fetal spine position was not known by the operator or to group B where the operator knew it. The main outcome was the success of MRFO in the two groups. Secondary outcomes were perineal injuries, blood loss, duration of expulsive period, and neonatal APGAR at 5 minutes. A priori knowledge of the spine position improves the success of the MRFO (41.4% group A versus 82.8% group B, p value < 0.001), the percentage of spontaneous deliveries (27.6% group A versus 69% group B, p value = 0.01), and maternal outcome (intact perineum and blood loss). No differences were detected on the neonatal side. MRFO is a safe and useful procedure that should be performed in second-stage arrest in OPP. A better performance was observed when supported by the US knowledge of the spine position. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound 45:472-476, 2017. © 2017 Wiley Periodicals, Inc.

  8. Wild jackdaws' reproductive success and their offspring's stress hormones are connected to provisioning rate and brood size, not to parental neophobia.

    Many species show individual variation in neophobia and stress hormones, but the causes and consequences of this variation in the wild are unclear. Variation in neophobia levels could affect the number of offspring animals produce, and more subtly influence the rearing environment and offspring development. Nutritional deficits during development can elevate levels of stress hormones that trigger long-term effects on learning, memory, and survival. Therefore measuring offspring stress hormone levels, such as corticosterone (CORT), helps determine if parental neophobia influences the condition and developmental trajectory of young. As a highly neophobic species, jackdaws (Corvus monedula) are excellent for exploring the potential effects of parental neophobia on developing offspring. We investigated if neophobic responses, alongside known drivers of fitness, influence nest success and offspring hormone responses in wild breeding jackdaws. Despite its consistency across the breeding season, and suggestions in the literature that it should have importance for reproductive fitness, parental neophobia did not predict nest success, provisioning rates or offspring hormone levels. Instead, sibling competition and poor parental care contributed to natural variation in stress responses. Parents with lower provisioning rates fledged fewer chicks, chicks from larger broods had elevated baseline CORT levels, and chicks with later hatching dates showed higher stress-induced CORT levels. Since CORT levels may influence the expression of adult neophobia, variation in juvenile stress responses could explain the development and maintenance of neophobic variation within the adult population.

    Atrioventricular node (AVN) ablation is an effective treatment for symptomatic patients with atrial arrhythmias who are refractory to rhythm and rate control strategies where optimal ventricular rate control is desired. There are limited data on the predictors of failure of AVN ablation. Our objective was to identify the predictors of failure of AVN ablation. This is an observational single-center study of consecutive patients who underwent AVN ablation in a large academic center. Baseline characteristics, procedural variables, and outcomes of AVN ablation were collected. AVN "ablation failure" was defined as resumption of AVN conduction resulting in recurrence of either rapid ventricular response or suboptimal biventricular pacing. A total of 247 patients drug refractory AF who underwent AVN ablation at our center with a mean age of 71 ± 12 years with 46% being males were included. Ablation failure was seen in 11 (4.5%) patients. There were no statistical differences between patients with "ablation failure" versus "ablation success" in any of the baseline clinical variables. Patients with moderate-to-severe tricuspid regurgitation (TR) were much more likely to have ablation failure than those with ablation success (8 [73%] vs 65 [27%]; p = 0.003). All 11 patients with ablation failure had a successful redo procedure, 9 with right and 2 with the left sided approach. On multivariate analysis, presence of moderate-to-severe TR was found to be the only predictor of failure of AVN ablation (odds ratio 9.1, confidence interval 1.99 to 42.22, p = 0.004). In conclusion, moderate-to-severe TR is a strong and independent predictor of failure of AVN ablation. Copyright © 2015 Elsevier Inc. All rights reserved.

    With increasing longevity in industrialized populations, there is growing interest in what defines "successful aging" (SA). Various SA measures have been proposed but no consensus has been reached and many have been criticized for not representing the views and priorities of older people. We consider whether the Rowe-Kahn SA model captures older individual's perceptions of their own health and aging. Using two cohorts of 886 and 483 men and women from the West of Scotland Twenty-07 Study, aged around 57 and 76, respectively, we explored associations between Rowe-Kahn SA dimensions (absence of disease/disability; good physical/cognitive functioning; good interpersonal/productive social engagement) and four aspects of self-rated health and satisfaction (current general health; health for age; satisfaction with health; satisfaction with life). Respondents' self-rated health and satisfaction was generally good but few had all six Rowe-Kahn dimensions positive, the conventional definition of SA. All individual positive SA dimensions were associated with better self-rated health and satisfaction. This was consistent across age, gender, manual/nonmanual occupations, and personality. The prevalence of good self-rated health and satisfaction increased with increasing numbers of positive SA dimensions. The Rowe-Kahn model provides a functional definition of SA. Future work on ageing should include all Rowe-Kahn dimensions and consider SA as a continuum. © The Author 2016.

    The use of a brace has been shown to be an effective treatment for hip dislocation in infants; however, previous studies of such treatment have been single-center or retrospective. The purpose of the current study was to evaluate the success rate for brace use in the treatment of infant hip dislocation in an international, multicenter, prospective cohort, and to identify the variables associated with brace failure. All dislocations were verified with use of ultrasound or radiography prior to the initiation of treatment, and patients were followed prospectively for a minimum of 18 months. Successful treatment was defined as the use of a brace that resulted in a clinically and radiographically reduced hip, without surgical intervention. The Mann-Whitney test, chi-square analysis, and Fisher exact test were used to identify risk factors for brace failure. A multivariate logistic regression model was used to determine the probability of brace failure according to the risk factors identified. Brace treatment was successful in 162 (79%) of the 204 dislocated hips in this series. Six variables were found to be significant risk factors for failure: developing femoral nerve palsy during brace treatment (p = 0.001), treatment with a static brace (p failure, whereas hips with 4 or 5 risk factors had a 100% probability of failure. These data provide valuable information for patient families and their providers regarding the important variables that influence successful brace treatment for dislocated hips in infants.

    Objective was to investigate the effect of sevoflurane anesthesia on heart rate (HR) fall with the injection of the initial drug in caudal space to confirm the correct needle placement. After the ethical approval was obtained from the hospital's ethics committee, a prospective randomized, clinical study was designed in Yeditepe University Hospital, in 2007. Children aged 1-12 years, scheduled for infraumblical surgery under general anesthesia and caudal block were included in the study. Anesthesia was induced and maintained by sevoflurane in group S (n=8) and by halothane in group H (n=82). Baseline HR was recorded before the caudal block was performed. The HR changes during the initial dose and total drug injection was recorded followed by 2 more HR recordings taken 5 and 10 minutes after caudal injection. The success of the block was recorded by a blind observer. There were 167 children included in the study. Caudal block success was 96.5% in group S and 97.6% in group H. Basal HR was 110.9+-10.9 in group S and 105.9+-10.1 in group H. Following the initial drug injection, mean HR was 109.8+-10.9 in group S and 102.9+-9.9 in group H. It was significantly lower than the baseline in group. The only significant decrease in the HR of the patients in group S was at the tenth minute following caudal injection. The decrease in HR with drug injection has no value to predict the success of caudal block under sevoflurane anesthesia. (author)

    There are many approaches to solving the problem of underrepresentation of some racial and ethnic groups and women in scientific and technical disciplines. Here, the authors evaluate the association of a summer bridge program with the graduation rate of underrepresented minority (URM) students at a selective technical university. They demonstrate that this 5-week program prior to the fall of the 1st year contains elements reported as vital for successful student retention. Using multivariable survival analysis, they show that for URM students entering as fall-semester freshmen, relative to their nonparticipating peers, participation in this accelerated summer bridge program is associated with higher likelihood of graduation. The longitudinal panel data include more than 2,200 URM students.

    Purpose: to analyze the clinical success rate and the findings of magnetic resonance imaging (MRI) after uterine artery embolization of symptomatic leiomyomas (fibroids) of the uterus. Materials and methods: this is a prospective single-center case study of 80 consecutively treated patients, followed for 3-6 months (group I), 7-12 months, (group II), and 13-25 months (group III). MRI was used to determine the uterine volume and size of the dominant leiomyoma. Symptoms and causes requiring repeat interventions were analyzed. Results: significant (p < 0.01) volume reduction of the uterus (median: 34.95% confidence interval [CI]: 30.41 - 41.76%) and dominant leiomyoma (median: 52.07%, CI: 47.71 - 61.57%) was found. The decrease in uterine volume (I-III: 22.68%, 33.56%, 47.93%) and dominant leiomyoma volume (I-III: 41.86%, 62.16%, 73.96%) progressed with the follow-up time. Bleeding resolved significantly (p < 0.0001) in all three follow-up groups (groups I-III: 92.86%, 95.23%, 96.67%). Furthermore, urinary frequency (groups I-III: 70%, 75%, 82.35%) and sensation of pelvic pressure (groups I-III: 42.86%, 60%, 93.75%) improved, which was statistically significant in group III (p < 0.01). The number of leiomyomas correlated (p < 0.05) with improvement of the bleeding and the pelvic pressure. Repeat therapy was necessary for complications in four patients (5%) and for therapeutic failure in three patients (3.8%). Permanent amenorrhea was observed in four patients (5%) of age 45 years or older. Conclusion: uterine artery embolization of uterine leiomyomas has a high clinical success rate with an acceptable incidence of complications and repeat interventions. (orig.)

    To assess: the reasons behind an operator choosing to perform radial artery catheterisation (RAC) as against femoral arterial catheterisation, and to explore why RAC may fail in the real world. A pre-determined analysis of PREVAIL study database was performed. Relevant data were collected in a prospective, observational survey of 1,052 consecutive patients undergoing invasive cardiovascular procedures at nine Italian hospitals over a one month observation period. By multivariate analysis, the independent predictors of RAC choice were having the procedure performed: (1) at a high procedural volume centre; and (2) by an operator who performs a high volume of radial procedures; clinical variables played no statistically significant role. RAC failure was predicted independently by (1) a lower operator propensity to use RAC; and (2) the presence of obstructive peripheral artery disease. A 10-fold lower rate of RAC failure was observed among operators who perform RAC for > 85% of their personal caseload than among those who use RAC < 25% of the time (3.8% vs. 33.0%, respectively); by receiver operator characteristic (ROC) analysis, no threshold value for operator RAC volume predicted RAC failure. A routine RAC in all-comers is superior to a selective strategy in terms of feasibility and success rate.

    External cephalic version is a medical procedure in which the fetus is externally manipulated to assume the cephalic presentation. The use of neuraxial analgesia for facilitating the version has been evaluated in several randomized clinical trials, but its potential effects are still controversial. The objective of the study was to evaluate the effectiveness of neuraxial analgesia as an intervention to increase the success rate of external cephalic version. Searches were performed in electronic databases with the use of a combination of text words related to external cephalic version and neuraxial analgesia from the inception of each database to January 2016. We included all randomized clinical trials of women, with a gestational age ≥36 weeks and breech or transverse fetal presentation, undergoing external cephalic version who were randomized to neuraxial analgesia, including spinal, epidural, or combined spinal-epidural techniques (ie, intervention group) or to a control group (either intravenous analgesia or no treatment). The primary outcome was the successful external cephalic version. The summary measures were reported as relative risk or as mean differences with a 95% confidence interval. Nine randomized clinical trials (934 women) were included in this review. Women who received neuraxial analgesia had a significantly higher incidence of successful external cephalic version (58.4% vs 43.1%; relative risk, 1.44, 95% confidence interval, 1.27-1.64), cephalic presentation in labor (55.1% vs 40.2%; relative risk, 1.37, 95% confidence interval, 1.08-1.73), and vaginal delivery (54.0% vs 44.6%; relative risk, 1.21, 95% confidence interval, 1.04-1.41) compared with those who did not. Women who were randomized to the intervention group also had a significantly lower incidence of cesarean delivery (46.0% vs 55.3%; relative risk, 0.83, 95% confidence interval, 0.71-0.97), maternal discomfort (1.2% vs 9.3%; relative risk, 0.12, 95% confidence interval, 0

    Full Text Available Abstract Background Luteal support with progesterone is necessary for successful implantation of the embryo following egg collection and embryo transfer in an in-vitro fertilization (IVF cycle. Progesterone has been used for as little as 2 weeks and for as long as 12 weeks of gestation. The optimal length of treatment is unresolved at present and it remains unclear how long to treat women receiving luteal supplementation. Design The trial is a prospective, randomized, double-blind, placebo-controlled trial to investigate the effect of the duration of luteal support with progesterone in IVF cycles. Following 2 weeks standard treatment and a positive biochemical pregnancy test, this randomized control trial will allocate women to a supplementary 8 weeks treatment with vaginal progesterone or 8 weeks placebo. Further studies would be required to investigate whether additional supplementation with progesterone is beneficial in early pregnancy. Discussion Currently at the Hewitt Centre, approximately 32.5% of women have a positive biochemical pregnancy test 2 weeks after embryo transfer. It is this population that is eligible for trial entry and randomization. Once the patient has confirmed a positive urinary pregnancy test they will be invited to join the trial. Once the consent form has been completed by the patient a trial prescription sheet will be sent to pharmacy with a stated collection time. The patient can then be randomized and the drugs dispensed according to pharmacy protocol. A blood sample will then be drawn for measurement of baseline hormone levels (progesterone, estradiol, free beta-human chorionic gonadotrophin, pregnancy-associated plasma protein-A, Activin A, Inhibin A and Inhibin B. The primary outcome measure is the proportion of all randomized women that continue successfully to a viable pregnancy (at least one fetus with fetal heart rate >100 beats/minute on transabdominal/transvaginal ultrasound at 10 weeks post embryo

    To explore the feasibility of CT attenuation value (CTvalue) to predict the composition of upper urinary calculi and the number of shock waves (NSW) and success rate (SR) of extracorporeal shock wave lithotripsy (ESWL). A total of 146 patients with upper urinary calculi treated by ESWL were included. CT scan was performed before ESWL. Upper urinary calculi with the maximum diameters of less than or equal to 2 cm were included. Infrared spectroscopy was used to analyze the composition of calculi. The effect of ESWL was estimated at 1 month followup. The factors that influence NSW and SR of ESWL were analyzed by correlation analysis. The CTvalue of calcium calculi were larger than that of noncalcium calculi ( P ESWL and CTvalues of calculi between the patients with different ages,skintostone distances and genders were not statistically significant. The partial correlation analysis found that CTvalue and long diameter of calculi were positively correlated with the NSW ( P ESWL ( P ESWL in subgroup analysis. The power of CTvalue to predict upper urinary calculi composition is insufficient. Higher CTvalue suggests more NSW in ESWL,but CTvalue is not suitable to predict SR of ESWL.

    Research in various fields generally investigates systems and involves latent variables. One method to analyze the model representing the system is path analysis. The data of latent variables measured using questionnaires by applying attitude scale model yields data in the form of score, before analyzed should be transformation so that it becomes data of scale. Path coefficient, is parameter estimator, calculated from scale data using method of successive interval (MSI) and summated rating scale (SRS). In this research will be identifying which data transformation method is better. Path coefficients have smaller varieties are said to be more efficient. The transformation method that produces scaled data and used in path analysis capable of producing path coefficients (parameter estimators) with smaller varieties is said to be better. The result of analysis using real data shows that on the influence of Attitude variable to Intention Entrepreneurship, has relative efficiency (ER) = 1, where it shows that the result of analysis using data transformation of MSI and SRS as efficient. On the other hand, for simulation data, at high correlation between items (0.7-0.9), MSI method is more efficient 1.3 times better than SRS method.

    Olive mill wastewater (OMW) spraying effects onto olive-tree fields were investigated. Three OMW levels (50, 100 and 200 m(3)ha(-1)year(-1)) were applied over six successive years. Olive-crop yields, phenolic compounds progress, phytotoxicity and microbial counts were studied at different soil depths. Olive yield showed improvements with OMW level applied. Soil polyphenolic content increased progressively in relation to OMW levels in all the investigated layers. However, no significant difference was noted in lowest treatment rate compared to the control field. In the soil upper-layers (0-40 cm), five phenolic compounds were identified over six consecutive years of OMW-spraying. In all the soil-layers, the radish germination index exceeded 85%. However, tomato germination test values decreased with the applied OMW amount. For all treatments, microbial counts increased with OMW quantities and spraying frequency. Matrix correlation showed a strong relationship between soil polyphenol content and microorganisms, and a negative one to tomato germination index. Copyright © 2012 Elsevier B.V.

    Full Text Available The drugs we use to treat any condition – from an innocuous cough to a lifethreatening cancer – are the outcome of painstaking human clinical trials. These trials are the only way to credibly determine the safety and efficacy of drugs. In recent years there has been a clear shift in clinical trial sites from core developed countries like USA, European countries to developing countries like India, China, South American countries. This shift is related to challenges and opportunities like costs of trials, recruitment issues, and regulatory challenges in developed vs. developing countries. Developing countries and developed countries have their unique disease burden patterns based on various parameters like but not limited to age, health care facilities, health insurance, sanitary conditions, environmental issues, education, nutrition and GDP. Previous studies have reported that many of the important global diseases are not much explored in clinical trials and many published clinical trials have very less international health relevance. This study was aimed at finding the correlation between disease burdens, number of clinical trials done and trial success rates. We compared 2005-2010 Global Burden of Disease data for Germany, India and number of clinical trials from clinicaltrials.gov database done in the same period. Our findings indicated that there was a good correlation between the disease burden and clinical trials for Germany in 2005 and 2010. For India in 2005 there was a moderate positive correlation, 2010 data showed the improvement in India in terms of match between disease burden and clinical Trials. But careful observation of the data shows still a need for more trials on Communicable, maternal, neonatal and nutritional disorders.

    Purpose: Percutaneous endoscopic gastrostomy (PEG) and percutaneous radiologic gastrostomy (PRG) are the standard methods of ensuring long-term enteral food intake in patients with dysphagia caused by neoplasia or neurological disorders. High-grade obstructions of the upper digestive tract or inadequate transillumination can prevent PEG. CT-guided percutaneous gastrostomy (PG) represents a special technique for enabling gastrostomy in patients for whom the endoscopic method is impossible. The aim of this study was to evaluate the results and complications of CT-guided percutaneous gastrostomy. Materials and Methods: CT-guided PG was performed in 83 patients, mostly with malignancy of the upper respiratory or digestive tract. Medical records for these patients were reviewed, and the results and complications of the CT-guided PG were analyzed retrospectively. Complications were grouped into four categories: Major and minor complications as well as early and late complications. Results: In 95.2 % of all cases (79/83), CT-guided PG was successful in the first attempt. Within the first 3 days, 5 major complications including 4 tube dislocations and one case of peritonitis were found in 4/79 patients (5.1 %). One of these patients experienced two early major complications. Early minor complications, mainly local skin irritations and temporary stomachache, were observed in 31 patients (39.2 %). Three days after CT-guided PG, 4 cases of major complications were documented, yielding a total rate of major complications was 8.7 % (7/79). Hemorrhage requiring blood transfusion or perforation after gastrostomy was not observed. 29.1 % of the patients (23/79) experienced late minor complications. (orig.)

    To assess the success and stability of 6-, 7-, 8-, and 9-mm-long, 6.5-mm-wide-neck tissue-level implants placed at the time of transalveolar sinus augmentation therapy, utilizing a trephine and osteotome approach, which were restored with single crowns. In total, 1,344 implants were placed by the author, varying in length from 6 to 9 mm, with parallel-wall 4.8-mm-diameter implant bodies and 6.5-mm-diameter implant necks. The implants were restored with single abutments and crowns by a variety of practitioners. They were followed for 60 to 229 months in function, with a mean time of 121.1 months in function. Implant success was evaluated by the author utilizing a combination of the Albrektsson et al criteria, and buccal and palatal/lingual bone sounding under anesthesia. The overall cumulative success rate was 98.8%. One hundred ninety 6-mm-long implants demonstrated a cumulative success rate of 97.5% at a mean time of 109.2 months in function. Eleven 7-mm-long implants demonstrated a cumulative success rate of 100% at a mean time of 218.5 months in function. One thousand ninety-four 8-mm-long implants demonstrated a cumulative success rate of 98.9% at a mean time of 112.3 months in function. Forty-nine 9-mm-long implants demonstrated a cumulative success rate of 100% at a mean time of 212.1 months in function. Implants of 6 to 9 mm in length, placed at the time of trephine and osteotome transalveolar sinus elevation procedures and restored with abutments and single crowns, demonstrate a high level of long-term clinical success, assuming specific comprehensive treatment criteria are met.

    To analyze the success rate, time to passage of tissue and subjective patient experience of a newly implemented protocol for medical management of early pregnancy failure (EPF) over a 2-year period. A retrospective chart review of all patients with early pregnancy failure primarily opting for medical management was performed. 200 mg mifepristone were administered orally, followed by a single vaginal dose of 800 mcg misoprostol after 36-48 h. We followed-up with our patients using a written questionnaire. 167 women were included in the present study. We observed an overall success rate of 92 %, defined as no need for surgical management after medication administration. We could not identify predictive values for success in a multivariate regression analysis. Most patients (84 %) passed tissue within 6 h after misoprostol administration. The protocol was well tolerated with a low incidence of side effects. Pain was managed well with sufficient analgesics. Responders to the questionnaire felt adequately informed prior to treatment and rated their overall experience as positive. The adaption of the institutional medical protocol resulted in a marked improvement of success rate when compared to the previously used protocol (92 vs. 61 %). We credit this increase to the adjusted medication schema as well as to targeted physician education on the expected course and interpretation of outcome measures. Our results underscore that the medical management of EPF is a safe and effective alternative to surgical evacuation in the clinical setting.

Substantial failure rates in higher injury grades remain common, with one large study reporting rates of 19.6%, 33.3%, and 75% for grades III, IV, and V, respectively. Retrospective data show angiography and embolization can increase salvage rates in these severe injuries. We developed a protocol requiring referral of all blunt splenic injuries, grades III to V, without indication for immediate operation for angiography and embolization. We hypothesized that angiography and embolization of high-grade blunt splenic injury would reduce NOM failure rates in this population. This was a prospective study at our Level I trauma center as part of a performance-improvement project. Demographics, injury characteristics, and outcomes were compared with historic controls. The protocol required all stable patients with grade III to V splenic injuries be referred for angiography and embolization. In historic controls, referral was based on surgeon preference. From January 1, 2010 to December 31, 2012, there were 168 patients with grades III to V spleen injuries admitted; NOM was undertaken in 113 (67%) patients. The protocol was followed in 97 patients, with a failure rate of 5%. Failure rate in the 16 protocol deviations was 25% (p = 0.02). Historic controls from January 1, 2007 to December 31, 2009 were compared with the protocol group. One hundred and fifty-three patients with grade III to V injuries were admitted during this period, 80 (52%) patients underwent attempted NOM. Failure rate was significantly higher than for the protocol group (15%, p = 0.04). Use of a protocol requiring angiography and embolization for all high-grade spleen injuries slated for NOM leads to a significantly decreased failure rate. We recommend angiography and embolization as an adjunct to NOM for all grade III to V splenic injuries. Copyright © 2014 American College of Surgeons. Published by Elsevier Inc. All rights reserved.

    The purpose of this study was to compare the effectiveness of mental incisive nerve block (MINB) and inferior alveolar nerve block (IANB) that were given alone or in combination to provide anesthesia to symptomatic mandibular premolars. One hundred fifty-three patients participated in this randomized, double-blind clinical trial. The patients were divided into 3 groups; first group received MINB with 2 mL 2% lidocaine with 1:200,000 epinephrine and a mock IANB with 2 mL sterile saline, patients in group 2 received mock MINB and an IANB with 2 mL 2% lidocaine, and patients in group 3 received both MINB and IANB with 2 mL each of 2% lidocaine. Access cavity preparation was initiated after 10 minutes. Success was defined as no pain or faint/weak/mild pain during endodontic access preparation and instrumentation. The anesthetic success rates were analyzed with Pearson χ(2) test at 5% significance levels. The MINB and IANB gave 53% and 47% anesthetic success rates, respectively, with no significant difference between them. Adding an IANB to MINB significantly improved the success rates to 82%. A combination of MINB and IANB can provide improved local anesthesia for symptomatic mandibular premolars. Copyright © 2016 American Association of Endodontists. Published by Elsevier Inc.

    The quality of life consequences of erectile dysfunction (ED) include depression, anxiety, and loss of self-esteem. The Self-Esteem And Relationship (SEAR) questionnaire is a validated, patient-administered, psychometric instrument specific to ED. To determine correlations between erectile function (EF), intercourse success, and emotional well-being measured with the SEAR questionnaire in men treated with sildenafil citrate for ED and stratified by age ( 65 years). This was an open-label, flexible-dose trial of sildenafil (25, 50 and 100 mg) administered for 10 weeks to 382 men with ED (mean +/- SD age, 55 +/- 13 years; mean ED duration, 4 years), which was conducted at 62 centers in the United States. Analysis (by intent-to-treat, n = 368) of the change from baseline to the week-10 endpoint in the SEAR questionnaire Self-Esteem subscale, the intercourse success rate (percent of occasions at which an erection that lasted long enough for successful intercourse was achieved), and their correlation. For the overall population, there was mean +/- SD improvement (p Erectile Function; event log frequency of erection hard enough for sexual intercourse and of ejaculation/orgasm) also improved (p 65 years, and six were positive in men aged erectile function and an increased intercourse success rate, which correlated positively with improvement in SEAR measures of self-esteem and sexual relationship.

    Full Text Available The emerging concept of successful aging is based on evidence that in healthy individual when they get aged, there are  considerable variations in physiological functions alteration. Some people exhibiting greater, but others very few or no age related alteration. The first is called poor aging and the later is called successful pattern of aging (Lambert SW, 2008. Thus, in the simple words the successful aging concept is define as an opportunity of old people to stay  active and productive condition despite they get aged chronologically. Aging itself might be defined as the progressive accumulation of changes with time associated with or responsible for the ever-increasing susceptibility to disease and death which accompanies advancing age (Harman D, 1981. The time needed to accumulate changes is attributable to aging process. The marked emerging questions are how does aging happen and where does aging start? To answer these questions and because of the complexity of aging process, there are more than 300 aging theories have been proposed to explain how and where aging occured and started respectively. There are too many to enumerate theories and classification of aging process. In summary, all of these aging theories can be grouped into three clusters: 1. Genetics program theory, this theory suggests that aging is resulted from program directed by the genes; 2. Epigenetic theory, in these theory aging is resulted from environmental random events not determined by the genes; 3. Evolutionary theory, which propose that aging is a medium for disposal mortal soma in order to avoid competition between organism and their progeny for food and space, did not try to explain how aging occur, but possibly answer why aging occur (De la Fuente. 2009. Among the three groups of aging theories, the epigenetic theory is useful to explain and try to solve the enigma of aging which is prominently caused by internal and external environmental influences

    The purpose of this study was to evaluate the clinical, radiographic, and patient-based outcomes of dental implants placed at an undergraduate student dental clinic. A retrospective study was performed to determine the success and survival rates of dental implants placed at the undergraduate dental clinic at Dalhousie University between January 1999 and January 2012. Only patients with a minimum of 1-year follow-up were included. Clinical and radiographic assessments determined implant success and survival rates. Questionnaires recorded patients' satisfaction with esthetics, comfort, and ease of hygiene. Of the 352 patients (n = 591 implants) who received implants over 13 years, 165 patients completed the clinical and radiographic examinations. By the end of the study period, demographic information and implant characteristics were collected for 111 (n = 217 implants; 47.5% in the maxilla, 52.6% in the mandible) of these patients. Of those assessed clinically, 36.4% were males and 63.6% females, with a mean age of 56.1 ± 14.15 years (range, 17 to 86 years) at the time of implant placement. The mean follow-up period was 5.8 years (range, 1 to 13 years). The overall implant success and survival rates were 88.0% and 97.2%, respectively. No observable bone loss was evident in 88.0% of the surviving implants. There were no implant fractures. Most patients (91.2%) were very satisfied with the implant restoration appearance, 88.0% were very comfortable with the implant, 92.6% were very satisfied with their ability to chew, and 84.8% reported easy hygiene maintenance at the implant sites. Implant success and survival in an undergraduate student clinic were comparable to those reported in the literature. It seems that inexperienced students were able to provide restorations that were very satisfying to the patients.

    To report the use of cumulative live-birth rates (CLBRs) per ovarian stimulation cycle to measure the success of IVF is proving to be the most accurate method for advising couples who failed to conceive, although the accuracy yielded is relatively low, and cycle outcome is highly dependent on the number of embryos replaced. Our aim with this work is to report the CLBRs of IVF as a function of the number of embryos required to reach a live birth (EmbR), considering age, day of ET, and infertility etiology. Survival curves and Kaplan-Meier methods to analyze CLBR in a retrospective cohort with respect to the number of EmbR. University-affiliated infertility center. Infertile couples undergoing IVF using own oocytes. None. CLBR per embryo transferred. CLBRs increase rapidly between 1 and 5 EmbR, moderately between 5 and 15, and slowly thereafter. Live-birth rates rise more slowly when embryos are transferred on days 2-3 rather than on days 5-6, with comparable long-term results. Women's age is a negative factor from 35 to 37 years old, with a dramatic decrease in live-birth rates beyond age 40 years. In addition, there are significant worse results in endometriosis patients. The relationship between CLBR and number of EmbR provides realistic and precise information regarding IVF success and can be used to guide couples and practitioners.

    Peripheral intravenous cannula (PIVC) insertion is one of the most common clinical interventions performed in emergency care worldwide. However, factors associated with successful PIVC placement and maintenance are not well understood. This study seeks to determine the predictors of first time PIVC insertion success in emergency department (ED) and identify the rationale for removal of the ED inserted PIVC in patients admitted to the hospital ward. Reducing failed insertion attempts and improving peripheral intravenous cannulation practice could lead to better staff and patient experiences, as well as improving hospital efficiency. We propose an observational cohort study of PIVC insertions in a patient population presenting to ED, with follow-up observation of the PIVC in subsequent admissions to the hospital ward. We will collect specific PIVC observational data such as; clinician factors, patient factors, device information and clinical practice variables. Trained researchers will gather ED PIVC insertion data to identify predictors of insertion success. In those admitted from the ED, we will determine the dwell time of the ED-inserted PIVC. Multivariate regression analyses will be used to identify factors associated with insertions success and PIVC failure and standard statistical validation techniques will be used to create and assess the effectiveness of a clinical predication rule. The findings of our study will provide new evidence to improve insertion success rates in the ED setting and identify strategies to reduce premature device failure for patients admitted to hospital wards. Results will unravel a complexity of factors that contribute to unsuccessful PIVC attempts such as patient and clinician factors along with the products, technologies and infusates used.

    Background The ability to lie still in an MRI scanner is essential for obtaining usable image data. To reduce motion, young children are often sedated, adding significant cost and risk. Objective We assessed the feasibility of using a simple and affordable behavioral desensitization program to yield high-quality brain MRI scans in sedation-free children. Materials and methods 222 children (4–9.9 years), 147 with type 1 diabetes and 75 age-matched non-diabetic controls, participated in a multi-site study focused on effects of type 1 diabetes on the developing brain. T1-weighted and diffusion-weighted imaging (DWI) MRI scans were performed. All children underwent behavioral training and practice MRI sessions using either a commercial MRI simulator or an inexpensive mock scanner consisting of a toy tunnel, vibrating mat, and video player to simulate the sounds and feel of the MRI scanner. Results 205 children (92.3%), mean age 7±1.7 years had high-quality T1-W scans and 174 (78.4%) had high-quality diffusion-weighted scans after the first scan session. With a second scan session, success rates were 100% and 92.5% for T1-and diffusion-weighted scans, respectively. Success rates did not differ between children with type 1 diabetes and children without diabetes, or between centers using a commercial MRI scan simulator and those using the inexpensive mock scanner. Conclusion Behavioral training can lead to a high success rate for obtaining high-quality T1-and diffusion-weighted brain images from a young population without sedation. PMID:24096802

    Objective: To determine if concomitant CT-guided biopsy and percutaneous fiducial seed placement in the lung can be performed in a selective patient population without increased complication or decreased success rates compared to either procedure alone. Materials and methods: An IRB approved retrospective analysis of 285 consecutive patients that underwent CT-guided placement of fiducial seeds in the lung alone (N = 63), with concomitant core biopsy (N = 53) or only core biopsy (N = 169) was performed. Variables compared included: patient demographics, lesion size, depth from pleura, needle size, number of passes through pleura, number and size of core biopsies, number of seeds placed and technical success rates. Statistical analysis was performed using univariate and multivariate pair-wise comparisons. Results: A pathologic diagnosis of malignancy was confirmed in all cases undergoing seed placement alone and seed placement with concurrent biopsy, and in 144 of the biopsy alone lesions. On univariate analysis, major complication rates were similar for all three groups as were lesion size, depth, number of pleural passes, and technical success. Pair-wise comparisons of the remaining variables demonstrated a significant younger age and smaller needle size in the biopsy only group, and less minor complications in the fiducial only group. Overall there were 80/285 (28.1%) minor and 29/285 (10.2%) major complications. All major complications leading to admission consisted of either pneumothorax or hemothorax, while minor complications included asymptomatic stable or resolving pneumothoraces, transient hemoptysis or small hemothoraces. Conclusions: A combined procedure of percutaneous pulmonary core biopsy and stereotactic seed placement can be performed without additional risk of a major complication when compared to performing these separately.

    Cement-retained implant-supported restorations have advantages over screw-retained restorations but are difficult to retrieve. Identifying the approximate location of the screw access hole (SAH) may reduce damage to the prosthesis. The purpose of this in vitro study was to evaluate the ability of cone beam computed tomography (CBCT) imaging to determine the location and direction of SAHs in cement-retained implant prostheses. Five clear acrylic resin casts were made based on a mandibular model. Several implant osteotomies (n=30) were created on the models with surgical burs, and crowns were made using the standard laboratory method with a transfer coping and the closed tray impression technique. CBCT images from the acrylic resin casts were evaluated by a maxillofacial radiologist who was blind to the locations and angles of the osteotomies. The locations of the access holes were determined on multiplanar reconstruction images and transferred to the clinical crown surface as defined points. Based on cross-sectional images, the predicted angle of the access hole was provided to a prosthodontist who was requested to pierce the crown at the proposed location in the specified direction. If the location and/or direction of the access hole were found, the process was considered successful, as the crown could then be removed from the implant abutment through the SAH. The success rate in the detection of the location and direction of the SAH was calculated, and chi-square and Fisher exact tests were applied for data analysis (α=.05). According to the results of this study, the success rate of CBCT to define the location of SAHs was 83.3% and 80% to determine the direction. No significant differences were found among the different dental groups in determination of the location (P=.79) or the direction (P=.53) of the SAHs. Most of the failures in determining the location and direction of the access hole in the buccolingual and mesiodistal directions were in the buccal and

  12. Population success.

    Science.gov (United States)

    1982-01-01

    "The commitment to population programs is now widespread," says Rafael Salas, Executive Director of the UNFPA, in its report "State of World Population." About 80% of the total population of the developing world live in countries which consider their fertility levels too high and would like them reduced. An important impetus came from the World Conference of 1974. The Plan of Action from the conference projected population growth rates in developing countries of 2.0% by 1985. Today it looks as though this projection will be realized. While in 1969, for example, only 26 developing countries had programs aimed at lowering or maintaining fertility levels, by 1980 there were 59. The International Population Conference, recently announced by the UN for 1984, will, it is hoped, help sustain that momentum. Cuba is the country which has shown the greatest decline in birth rate so far. The birth rate fell 47% between 1965-1970 and 1975-1980. Next came China with a 34% decline in the same period. After these came a group of countries--each with populations of over 10 million--with declines of between 15 and 25%: Chile, Colombia, India, Indonesia, the Republic of Korea, Malaysia and Thailand. Though birth rates have been dropping significantly the decline in mortality rates over recent years has been less than was hoped for. The 1974 conference set 74 years as the target for the world's average expectation of life, to be reached by the year 2000. But the UN now predicts that the developing countries will have only reached 63 or 64 years by then. High infant and child mortality rates, particularly in Africa, are among the major causes. The report identifies the status of women as an important determinant of family size. Evidence from the UNFPA-sponsored World Fertility Survey shows that in general the fertility of women decreases as their income increases. It also indicates that women who have been educated and who work outside the home are likely to have smaller families

    This randomized, double-blind, placebo-controlled, clinical trial was designed to improve the success of inferior alveolar nerve blocks (IANB) in mandibular molars with symptomatic irreversible pulpitis (SIP) by means of preoperative submucosal administration of 50 mg tramadol. Forty-two patients with a mandibular molar diagnosed with SIP took part in the trial. Patients were assigned randomly to one of two groups: tramadol group (n = 21), who received 50 mg tramadol in 1 mL by mandibular infiltration, and a placebo group (n = 21), who received 1 mL of normal saline administered to the affected tooth by the same means. Ten minutes later, all patients received an IANB with 4% articaine with epinephrine 1 : 100 000. A 10-min waiting time was established after local anaesthetic (LA) administration before carrying out three consecutive tests to assess anaesthesia of the pulp, that is two consecutive negative responses to an electric pulp test, positive or negative response to a cold test and no pain during access cavity preparation. IANB was considered successful only if the patient did not experience pain arising from these tests. Data were analysed by the Chi-squared frequency test and the Fisher's exact test, for qualitative variables, Mann-Whitney U-test for independent samples and two-way anova for more than two independent samples. In the tramadol group IANB was achieved successfully in 57% of the sample, whilst the placebo group obtained 29%. The difference between groups was not significant (P = 0.06). When performing endodontic access, the anaesthetic success rate was significantly in favour of tramadol (P = 0.03). Preoperative submucosal administration of 50 mg tramadol in mandibular molars with SIP significantly improved the success of IANB using 4% articaine with 1 : 100 000 epinephrine during access cavity preparation in comparison with a placebo. © 2017 International Endodontic Journal.

    Effects of sequential procedures required for cryopreservation of embryos excised from the recalcitrant seeds of Haemanthus montanus were assessed ultrastructurally and in conjunction with respiratory activity and the rate of protein synthesis. Fresh material (water content, 5.05 ± 0.92 g g(-1) dry mass) afforded ultrastructural evidence of considerable metabolic activity, borne out by respiratory rates. Neither exposure to glycerol nor sucrose as penetrating and non-penetrating cryoprotectants, respectively, brought about degradative changes, although increased vacuolation and autophagy accompanied both, while respiratory and protein synthetic activity were not adversely affected. Glycerol-cryoprotected embryos flash dried to water contents >0.4 g g(-1) showed organised ultrastructural features and considerable autophagy consistent with metabolic activity, and although respiratory activity was lower, protein synthesis rate was enhanced relative to fresh material. However, at water contents Success, assessed as ≥50% axes forming seedlings after cryogen exposure, was obtained only when glycerol-cryoprotected embryos at water contents >0.4 g g(-1)-in which the degree of vacuolation remained moderate-were rapidly cooled. The outcomes of this study are considered particularly in terms of the stresses imposed by prolonged, relatively slow dehydration and ultimate water contents, on embryos showing considerable metabolic activity.

    After localized 300 kV X-irradiation of the rat stomach the stomach emptying time of a liquid and a solid test meal was examined with a non-invasive radiological method. In the acute period one to three weeks after irradiation with single doses between 10.7 and 21.3 Gy we observed a faster emptying of the liquid and a delayed emptying of the solid test meal. The faster emptying of the liquid test meal was treated successfully with atropin. In the chromic period we observed a delayed emptying of the liquid and of the solid test meal. These emptying disorders were treated partially successfully with the parasympathomimeticum carbachol and they were treated completeley successfully with the dopamine antagonist metoclopramide.

    The evolution of the oxidative metabolism of (11)C acetate parallels the recovery of left ventricular(LV) contraction following acute myocardial infarction(AMI). This study was designed to unravel, for the first time, the impact of the global washout rate(WR) of (123)I-beta-methyl-p-iodophenylpentadecanoic acid (BMIPP) on the recovery of LV function followingAMI, as evidenced from conventional echocardiography.Twenty consecutive patients (age: 58 +/- 13 years; 16 males and 4 females) with ST-segment elevation myocardial infarction (STEMI) were enrolled and all of them underwent successful percutaneous coronary intervention (PCI). (123)I-BMIPP cardiac scintigraphy was performed at 7 +/- 3 days after admission. The WR was calculated from the polar map and the regional BMIPP defect score was calculated using a 17 segment model. Echocardiography was performed within 24 h of admission and at 3 months to record the ejection fraction (EF), the wall motion score index (WMSI), the ratio of the mitralinflow velocity to the early diastolic velocity (E/E0)and the myocardial performance index (MPI). The mean global WR of the BMIPP was 22.12 +/- 7.22%, and it was significantly correlated with the improvement of the WMSI (r = 0.61, P\\0.004). However,the relative changes of the EF, E/E0 and MPI were not correlated with the WR. The BMIPP defect score (18 +/- 10) was significantly correlated with the WMSI on admission (r = 0.74, P = 0.0002), but the defect score was not correlated with the relative changes of any of the echocardiographic parameters. We proved that the WR of the BMIPP is a promising indicator of improvement of the LV wall motion (WMSI) following ST-segment elevation myocardial infarction and successful reperfusion.

  17. The discovery of how gender influences age immunological mechanisms in health and disease, and the identification of ageing gender-specific biomarkers, could lead to specifically tailored treatment and ultimately improve therapeutic success rates

    Full Text Available Abstract The control of human health and diseases in the elderly population is becoming a challenge, since mean age and life expectation are progressively increasing as well as chronic degenerative diseases. These disorders are of complex diagnosis and they are difficult to be treated, but it is hoped that the predictive medicine will lead to more specific and effective treatment by using specific markers to identify persons with high risk of developing disease, before the clinical manifestation. Peripheral blood targets and biomarkers are currently the most practical, non-invasive means of disease diagnosing, predicting prognosis and therapeutic response. Human longevity is directly correlated with the optimal functioning of the immune system. Recent findings indicate that the sexual dimorphism of T helper (Th cytokine pathways and the regulation of Th cell network homeostasis are normally present in the immune response and undergoes to adverse changes with ageing. Furthermore, immune senescence affects both men and women, but it does not affect them equally. Therefore, we hypothesize that the comprehension of the interferences between these gender specific pathways, the ageing immunological mechanism in pathological or healthy state and the current therapies, could lead to specifically tailored treatment and eventually improve the therapeutic success rates. Reaching this aim requires the identification of ageing gender-specific biomarkers that could easily reveal the above mentioned correlations.

    About 120,000 reference samples are analyzed each year in the Forensic Laboratory of Lyon. A total of 1640 positive control experiments used to validate and optimize the analytical method in the routine process were submitted to a multivariate exploratory data analysis approach with the aim of better understanding the underlying sources of variability. The peak heights of the 16 genetic markers targeted by the AmpFℓSTR(®) Identifiler(®) STR kit were used as variables of interest. Six different 3130xl genetic analyzers located in the same controlled environment were involved. Two major sources of variability were found: (i) the DNA load of the sample modulates all peak heights in a similar way so that the 16 markers are highly correlated, (ii) the genetic analyzer used with a locus-specific response for peak height and a better sensitivity for the most recently acquired. Three markers (FGA, D3S1358, and D13S317) were found to be of special interest to predict the success rate observed in the routine process. © 2014 American Academy of Forensic Sciences.

    Full Text Available Aims: To assess whether educating the parents, teachers, and intermediate school children of Amritsar city about the emergency management of tooth avulsion was an effective method of increasing success rate of treatment of avulsion. Subjects and Methods: Self-administered questionnaires were prepared for 200 parents, teachers, and for intermediate school children to assess baseline knowledge. Sociodemographic distribution of the targeted group was carried out applying Kuppuswamy scale. Two months later, flip cards and posters were distributed to the selected sample followed by a reinforcement session conducted after 1 month in the form of slide presentations on dental trauma. After 3 months, reassessment performance was distributed to the same participants for reassessing any change in baseline knowledge. Further analysis of knowledge, attitude, and practices were carried out after 6 months. The scores based on Likert scale ranging 0-3 were obtained and put to statistical analysis to analyze efficacy of this program 12 months from baseline data. Results and Conclusion: Wilcoxon signed ranked test was applied to nonparametric data to study the knowledge before and after education was carried out. There was a significant change in the knowledge level of children, teachers, and parents after the campaign and teachers showed more positive change in the practice of emergency management of tooth avulsion, endorsing the fact that comprehensive dental education programs targeting school teachers and children can change the perspective of individuals toward treatment needs for dental trauma involving avulsion.

    The practicability, safety and clinical efficacy of intracavitary therapy with Re-186-colloid in patients with recurrent otitis media and paranasal sinusitis, resistant to pharmacotherapy and surgical treatment is demonstrated based on a preliminary treatment trial. Methods: the authors report on a total of 39 applications of 5-35 MBq {sup 186}Re-colloid into the tympanon and the paranasal sinuses in six patients. Biodistribution and biokinetics were studied by gamma camera imaging. Clinical success was documented 6-20 months after therapy both by patients self-evaluation and by objective rhinootological follow-up, using a four-step score from -1 to+2. Results: no serious side effects were seen. There was good to excellent clinical improvement with a mean score of +1.44 {+-} 0.5 by patients self-evaluation and by physicians scoring of +0.81 {+-} 0.9 with only negligible extracranial tracer deposition. Conclusion: this novel treatment option using intracavitary application of Re-186-colloid in chronic otitis media and sinusitis is safe and effective. The term Radio-Tympano-Sinu-Orthesis (RTSO) might be proposed analogously to the well-known radiosynoviorthesis (RSO). (orig.)

    . The difference in short- and long-term success rates increased with increasing gestational age. The majority of failures (76%) were diagnosed more than 2 weeks after initiation of the abortion. At a 2-week follow-up visit, the women who turned out to be failures had a larger endometrial width, higher beta......-hCG values and smaller reductions of beta-hCG than those treated successfully. To optimize comparison of success rates after different medical abortion regimens, we suggest that the criteria for success are stated clearly, that the success rates are stratified according to gestational age...

    leucócitos no dia da decanulação influenciaram no sucesso de remoção do traqueóstomo.INTRODUCTION: Tracheostomy is probably the most common surgical procedure in critically ill patients and is generally performed to facilitate mechanical ventilation weaning. Evidence-based guidelines have confirmed the benefits of tracheostomy weaning protocols and of the physiotherapists engagement in this process; however, no consensus decannulation criteria are currently available. Therefore, this study aimed to evaluate the influence of peripheral muscle strength and other indicators on decannulation success. METHODS: This was an observational retrospective study that analyzed the medical records of patients admitted to the medical and surgical intensive care unit of Hospital Agamenon Magalhães between March 2007 and August 2009. Respiratory and peripheral muscle strengths were evaluated in decannulated patients. RESULTS: Overall, 1,541 patients were evaluated, 143 of which had been tracheostomized, and only 57 of which had been decannulated. Forty-six patients had a satisfactory decannulation outcome, while 11 had decannulation failure, requiring the return to an artificial airway within 2 weeks. The calculated Medical Research Council peripheral muscle strength score was significantly lower for the failure group than for the successful decannulation group (28.33 ± 15.31 vs. 41.11 ± 11.52; P = 0.04. Scores above or equal 26 had 94.4% sensitivity and 50.0% specificity for the decannulation outcome, with an area under the ROC curve of 0.7593. In addition, white blood cell counts were higher in decannulation failure group patients (14,070 ± 3,073 vs. 10,520 ± 3,402 cells/μL; P = 0.00. CONCLUSION: This study has shown that peripheral muscle strength and blood leucocyte counts evaluated on the day of decannulation may influence the tracheostomy decannulation success rate.

    Although mandatory vaccination programs have been effective in improving the vaccination rate among healthcare workers, implementing this type of program can be challenging because of varied reasons for vaccine refusal. The purpose of our study is to measure improvement in the influenza vaccination rate from a multifaceted intervention at a Japanese tertiary care center where implementing a mandatory vaccination program is difficult. Before-and-after trial. Healthcare workers at a 550-bed, tertiary care, academic medical center in Sapporo, Japan. We performed a multifaceted intervention including (1) use of a declination form, (2) free vaccination, (3) hospital-wide announcements during the vaccination period, (4) prospective audit and real-time telephone interview for healthcare workers who did not receive the vaccine, (5) medical interview with the hospital executive for noncompliant (no vaccine, no declination form) healthcare workers during the vaccination period, and (6) mandatory submission of a vaccination document if vaccinated outside of the study institution. With the new multifaceted intervention, the vaccination rate in the 2012-2013 season increased substantially, up to 97%. This rate is similar to that reported in studies with a mandatory vaccination program. Improved vaccination acceptance, particularly among physicians, likely contributed to the overall increase in the vaccination rate reported in the study. Implementation of comprehensive strategies with strong leadership can lead to substantial improvements in vaccine uptake among healthcare workers even without a mandatory vaccination policy. The concept is especially important for institutions where implementing mandatory vaccination programs is challenging.

    1997-01-01

    Successful mergers in the context of long-term value creation, as measured by return realized on investor-provided capital, were discussed. In essence, a successful merger is characterized by being motivated by a sound business reason and strategy for the merger, a reasonable price and sound execution. The acquiror's pre-merger success in managing a company is a good indicator of future success. Poorly managed companies that acquire other companies generally continue to be poorly managed with no significant increase in shareholder value. Prior to the acquisition, identification of the potential target, assessment of the people involved on both sides of the transaction, thorough knowledge of the target's potential for value creation, financial implications (debt, equity, terms and demand, tax implications, the potential effect of the proposed acquisition on the acquiror's business plan) and finally the execution of the process itself, are the important determinants of successful mergers

    Bogomir Novak

    1997-12-01

    Full Text Available As competition is becoming ever more fierce, research into the prerequisites for success is gaining ground. By most people, success is perceived as an external phenomenon, but it is in fact the consequence of a person's readiness to perform in the world (of business. In the paper, Novak distinguishes between internal, external and group success. The essence of interna!success, which is the condition for the other two types of success, is assuming responsibility for, and exercising self-control over one's psychic phenomena. This in fact means that one needs to "reprogramme" the old patterns of behaviour and substitute them for the new, which leads to personality changes based on the understanding and acceptance of the self and others as they are. In realizing personal abilities, motives and goals, mental guiding laws must also be taken into account. Nowadays, the overall success of an organization is an important indicator of the quality of gro up work. The working patterns of individuals comply with the patterns used by his or her colleagues. When we do something for ourselves, we do it for others. In certain organizations, through accepted ways of communication all people become successful, and no body needs to be paid off. Employees wholly identify themselves with their organization, and vice versa. This three-part paradigm (I-Others-Community is the basis for various models of practical training for success, which are often idealized, but are primarily aimed at abolishing passivity and flaws in the system and its wider environment.

  9. Successful Enterprise System Re-Implementation

    Svejvig, Per

    2017-01-01

    Achieving success in enterprise systems (ES) implementations is challenging. The success rate is not high in view of the sums invested by many organizations in these companywide systems. The literature is charged with reasons for unsuccessful implementations, such as a lack of top management...... support and insufficient change management. Contrary to this research, empirical data from an ES re-implementation in a Scandinavian high-tech company shows successful implementation despite many problematic shifts in outsourcing partners. Therefore, it is natural to ask: why was the re......-implementation of the ES at SCANDI successful despite the major troubles encountered during the project? Building an analysis based on ten Critical Success Factors (CSFs) combined with an investigation into the institutional structures at play, we present several reasons for the successful implementation. The CSF analysis...

  10. Successful ageing for psychiatrists.

    Peisah, Carmelle

    2016-04-01

    This paper aims to explore the concept and determinants of successful ageing as they apply to psychiatrists as a group, and as they can be applied specifically to individuals. Successful ageing is a heterogeneous, inclusive concept that is subjectively defined. No longer constrained by the notion of "super-ageing", successful ageing can still be achieved in the face of physical and/or mental illness. Accordingly, it remains within the reach of most of us. It can, and should be, person-specific and individually defined, specific to one's bio-psycho-social and occupational circumstances, and importantly, reserves. Successful professional ageing is predicated upon insight into signature strengths, with selection of realistic goal setting and substitution of new goals, given the dynamic nature of these constructs as we age. Other essential elements are generativity and self-care. Given that insight is key, taking a regular stock or inventory of our reserves across bio-psycho-social domains might be helpful. Importantly, for successful ageing, this needs to be suitably matched to the professional task and load. This lends itself to a renewable personal ageing plan, which should be systemically adopted with routine expectations of self-care and professional responsibility. © The Royal Australian and New Zealand College of Psychiatrists 2015.

    The State Minister for Health and Family of Bangladesh, Dr. Mohammed Amanullah, highlighted some of the successes being achieved by his country in lowering fertility and improving the lives of the people since the 1994 International Conference on Population and Development. Some of these successes include practical measures to eliminate violence against women; introduction of a quota for women in public sector employment; and launching of the Health and Population Sector Program to provide a one-stop, full range of essential reproductive health, family planning and child health services through an integrated delivery mechanism. Moreover, the Minister informed the Forum participants that their success is attributable to many factors which include support from the government, from non-governmental organizations, civil society, mass media, religious and other community leaders, intersectoral collaboration, microcredit and income-generation activities.

    Full Text Available Setting and Objectives: Carnegie Mellon University (CMU recently planned and implemented a project to help CMU researchers get an Open Researcher and Contributor Identifier (ORCID and to enable administrators to integrate the ORCIDs into university systems. This article describes and assesses the planning, performance, and outcome of this initiative, branded ORCID @ CMU. Design and Methods: The article chronicles why and how ORCID was integrated at CMU, including the rationale for changes in strategic plans. It assesses researcher participation in the project using transaction log and content analyses, and the performance of the ORCID project team using recommendations in the Jisc ORCID project report, frankly reporting the team’s successes and failures. The article concludes with lessons learned that should inform ORCID integration projects and expectations at other institutions. Results: The ORCID @ CMU web application was a great success. However, the project team did not allow enough time to prepare or devote enough attention to advocacy. The marketing message was not sufficiently persuasive and the marketing channels were not particularly effective. The overall participation rate in ORCID @ CMU was far below the target of 40%, though participation in many demographics exceeded the goal. Conclusions: Strategic planning does not guarantee success. Secure more than lip service from senior administrators. Recruit champions from across the institution. Develop a message that resonates with researchers. Allow sufficient time to prepare. Empower the project manager. Start with the low hanging fruit. Develop special outreach to doctoral students and postdocs.

'The commissioning phase was a resounding success,' enthuses a satisfied Michel Chanel, head of the LEIR construction project. After several months of fine-tuning, the LEIR team has achieved its aim of producing the kind of beam required for first lead-ion collisions in the LHC in 2008. This involved creating bunches containing 230 million ions, in line with the specifications for those first beams. This success can be put down to the machine's outstanding design and components. 'It's a great achivement by all the teams involved in the machine's construction,' underlines Christian...

    The synchronization of the LHC's clockwise beam transfer system and the rest of CERN's accelerator chain was successfully achieved last weekend. Tests began on Friday 8 August when a single bunch of a few particles was taken down the transfer line from the SPS accelerator to the LHC. After a period of optimization, one bunch was kicked up from the transfer line into the LHC beam pipe and steered about 3 kilometres around the LHC itself on the first attempt. On Saturday, the test was repeated several times to optimize the transfer before the operations group handed the machine back for hardware commissioning to resume on Sunday. The anti-clockwise synchronization systems will be tested over the weekend of 22 August.Picture:http://lhc-injection-test.web.cern.ch/lhc-injection-test/

    The decommissioning of a nuclear power plant poses a significant challenge for the operating company. The business model is turned upside down and a working culture developed for power operation has to be adapted while necessary know- how for the upcoming tasks has to be built up. The trauma for the employees induced by the final plant shut-down has to be considered and respected. The change of working culture in the enterprise has to be managed and the organization has to be prepared for the future. Here the methods of Change-Management offer a systematic and effective approach. Confidence in the employee's competencies is one of the key success factors for the change into the future.

  3. Success in geothermal development

    International Nuclear Information System (INIS)

    Stefansson, V.

    1992-01-01

    Success in geothermal development can be defined as the ability to produce geothermal energy at compatible energy prices to other energy sources. Drilling comprises usually the largest cost in geothermal development, and the results of drilling is largely influencing the final price of geothermal energy. For 20 geothermal fields with operating power plants, the ratio between installed capacity and the total number of well in the field is 1.9 MWe/well. The drilling history in 30 geothermal fields are analyzed by plotting the average cumulative well outputs as function of the number of wells drilled in the field. The range of the average well output is 1-10 MWe/well with the mean value 4.2 MWe/well for the 30 geothermal fields studied. A leaning curve is defined as the number of wells drilled in each field before the average output per well reaches a fairly constant value, which is characteristic for the geothermal reservoir. The range for this learning time is 4-36 wells and the average is 13 wells. In general, the average well output in a given field is fairly constant after some 10-20 wells has been drilled in the field. The asymptotic average well output is considered to be a reservoir parameter when it is normalized to the average drilling depth. In average, this reservoir parameter can be expressed as 3.3 MWe per drilled km for the 30 geothermal fields studied. The lifetime of the resource or the depletion time of the geothermal reservoir should also be considered as a parameter influencing the success of geothermal development. Stepwise development, where the reservoir response to the utilization for the first step is used to determine the timing of the installment of the next step, is considered to be an appropriate method to minimize the risk for over investment in a geothermal field

  4. Colour for Behavioural Success

    Science.gov (United States)

    Reeves, Adam

    2018-01-01

    Colour information not only helps sustain the survival of animal species by guiding sexual selection and foraging behaviour but also is an important factor in the cultural and technological development of our own species. This is illustrated by examples from the visual arts and from state-of-the-art imaging technology, where the strategic use of colour has become a powerful tool for guiding the planning and execution of interventional procedures. The functional role of colour information in terms of its potential benefits to behavioural success across the species is addressed in the introduction here to clarify why colour perception may have evolved to generate behavioural success. It is argued that evolutionary and environmental pressures influence not only colour trait production in the different species but also their ability to process and exploit colour information for goal-specific purposes. We then leap straight to the human primate with insight from current research on the facilitating role of colour cues on performance training with precision technology for image-guided surgical planning and intervention. It is shown that local colour cues in two-dimensional images generated by a surgical fisheye camera help individuals become more precise rapidly across a limited number of trial sets in simulator training for specific manual gestures with a tool. This facilitating effect of a local colour cue on performance evolution in a video-controlled simulator (pick-and-place) task can be explained in terms of colour-based figure-ground segregation facilitating attention to local image parts when more than two layers of subjective surface depth are present, as in all natural and surgical images.

    A summary of the operating economics of the Winter Cummings Sand Pool, a horizontal well development project with a sustained rate of development, was presented. A total of 58 horizontal wells have been drilled over a time span of seven years. The production performance of the first pilot wells indicated that development of the pool by horizontal wells could be economically viable. Since its inception the Winter field development was considered to have become a capital treadmill with an incremental rate of return on the incremental investment of 240 percent (a 24 million dollar net operating cash flow for a 10 million dollar investment). Current development status and production forecasts were also discussed. 21 figs

    Yesterday morning, the last colliding proton beams of 2013 were extracted from the LHC, heralding the start of the machine’s first long shutdown (LS1) and crowning its first three glorious years of running. I hardly need to tell the CERN community what a fabulous performance all the people running the machine, the experiments, the computing and all supporting infrastructures put in. Those people are you, and you all know very well what a great job everyone did.   Nevertheless, I would like to express my thanks to all the people who made this first LHC run such a success. Re-measuring the whole Standard Model in such a short period, and then completing it with the discovery of what looks increasingly like the Higgs boson, is no mean feat. What I’d like to focus on today is another aspect of our field: its remarkable ability to adapt. When I started out in research, experiments involved a handful of people and lasted a few years at most. The timescale for the development of ...

  10. Assessing call centers’ success:

    Directory of Open Access Journals (Sweden)

    Hesham A. Baraka

    2013-07-01

    This paper introduces a model to evaluate the performance of call centers based on the Delone and McLean Information Systems success model. A number of indicators are identified to track the call center’s performance. Mapping of the proposed indicators to the six dimensions of the D&M model is presented. A Weighted Call Center Performance Index is proposed to assess the call center performance; the index is used to analyze the effect of the identified indicators. Policy-Weighted approach was used to assume the weights with an analysis of different weights for each dimension. The analysis of the different weights cases gave priority to the User satisfaction and net Benefits dimension as the two outcomes from the system. For the input dimensions, higher priority was given to the system quality and the service quality dimension. Call centers decision makers can use the tool to tune the different weights in order to reach the objectives set by the organization. Multiple linear regression analysis was used in order to provide a linear formula for the User Satisfaction dimension and the Net Benefits dimension in order to be able to forecast the values for these two dimensions as function of the other dimensions

  11. Obesity management: what brings success?

    Science.gov (United States)

    Lagerros, Ylva Trolle; Rössner, Stephan

    2013-01-01

    The upward trend in obesity prevalence across regions and continents is a worldwide concern. Today a majority of the world's population live in a country where being overweight or obese causes more deaths than being underweight. Only a portion of those qualifying for treatment will get the health care they need. Still, a minor weight loss of 5-10% seems to be sufficient to provide a clinically significant health benefit in terms of risk factors for cardiovascular disease and diabetes. Diet, exercise and behavior modifications remain the current cornerstones of obesity treatment. Weight-loss drugs play a minor role. Drugs which were available and reasonably effective have been withdrawn because of side effects. The fact that the 'old' well known, but pretty unexciting tools remain the basic armamentarium causes understandable concern and disappointment among both patients and therapists. Hence, bariatric surgery has increasingly been recognized and developed, as it offers substantial weight loss and prolonged weight control. The present review highlights the conventional tools to counter obesity, lifestyle modification, pharmacotherapy and bariatric surgery, including some of the barriers to successful weight loss: (1) unrealistic expectations of success; (2) high attrition rates; (3) cultural norms of self-acceptance in terms of weight and beliefs of fat being healthy; (4) neighborhood attributes such as a lack of well-stocked supermarkets and rather the presence of convenience stores with low-quality foods; and (5) the perception of the neighborhood as less safe and with low walkability. Prevention is the obvious key.

    What makes a marketing strategy implementation successful and how can managers measure this success? To answer these questions, we developed a two-step audit approach. First, managers should measure the implementation success regarding effectiveness, efficiency, performance outcomes, and strategic embeddedness. Second, they should explore the reasons that have led to success or failure by regarding managerial, leadership, and environmental traps. Doing so will also provide corrective action p...

Here we show that song performance reflects age and reproductive success in the rock sparrow (Petronia petronia...... nests. Older males could be distinguished from yearlings by singing at lower rate and higher amplitudes. Our findings suggest that song rate may be used as a signal of age and together with song pitch as a signal of reproductive success in this species. Alternatively, younger and less successful males...... success. Males with higher breeding success sang at a lower rate and with a higher maximum frequency. We found also that older males gained more extra-pair young and had a higher overall breeding success, although they also differed almost significantly by having a higher loss of paternity in their own...

    Full Text Available Penile amputation is an uncommon injury for which immediate surgical replantation is warranted. Microsurgical replantation is the “standard” method for penile replantation. Early replantation yields a high success and low complication rate. We report a case of a 34-year-old male who presented with amputation at the proximal penile shaft which was successfully replanted using microsurgical techniques. Minor skin necrosis was noted post-operatively which was debrided and covered with skin graft. Follow-up at 6 months showed satisfactory cosmetic appearance, normal voiding, return of sensations and erectile function. The level of evidence was V.

    The generalised assumption of health information systems (HIS) success is questioned by a few commentators in the medical informatics field. They point to widespread HIS failure. The purpose of this paper was therefore to develop a better conceptual foundation for, and practical guidance on, health information systems failure (and success). Literature and case analysis plus pilot testing of developed model. Defining HIS failure and success is complex, and the current evidence base on HIS success and failure rates was found to be weak. Nonetheless, the best current estimate is that HIS failure is an important problem. The paper therefore derives and explains the "design-reality gap" conceptual model. This is shown to be robust in explaining multiple cases of HIS success and failure, yet provides a contingency that encompasses the differences which exist in different HIS contexts. The design-reality gap model is piloted to demonstrate its value as a tool for risk assessment and mitigation on HIS projects. It also throws into question traditional, structured development methodologies, highlighting the importance of emergent change and improvisation in HIS. The design-reality gap model can be used to address the problem of HIS failure, both as a post hoc evaluative tool and as a pre hoc risk assessment and mitigation tool. It also validates a set of methods, techniques, roles and competencies needed to support the dynamic improvisations that are found to underpin cases of HIS success.

    Understanding processes and mechanisms governing changes in plant species along primary successions has been of major importance in ecology. However, to date hardly any studies have focused on the complete life cycle of species along a successional gradient, comparing pioneer, early and late-successional species. In this study it is hypothesized that pioneer species should initially have a population growth rate, lambda, greater than one with high fecundity rates, and declining growth rates when they are replaced by late-successional species. Populations of late-successional species should also start, at the mid-successional stage (when pioneer species are declining), with growth rates greater than one and arrive at rates equal to one at the late successional stage, mainly due to higher survival rates that allow these species to persist for a long time. The demography of pioneer- (Saxifraga aizoides), early (Artemisia genipi) and late-successional species (Anthyllis vulneraria ssp. alpicola) was investigated together with that of a ubiquitous species (Poa alpina) along the Rotmoos glacier foreland (2300-2400 m a.s.l., Central Alps, Austria) over 3 years. A matrix modelling approach was used to compare the main demographic parameters. Elasticity values were plotted in a demographic triangle using fecundity, individual growth and survival as vital rates contributing to the population growth rates. The results largely confirmed the predictions for population growth rates during succession. However, high survival rates of larger adults characterized all species, regardless of where they were growing along the succession. At the pioneer site, high mortality rates of seedlings, plantlets and young individuals were recorded. Fecundity was found to be of minor relevance everywhere, but it was nevertheless sufficient to increase or maintain the population sizes. Demographically, all the species over all sites behaved like late-successional or climax species in secondary

  1. Structuring lighting retrofit projects for success

    International Nuclear Information System (INIS)

    Fetters, J.L.

    1993-01-01

    Several trends are converging to create a substantial market for lighting retrofits in these uncertain economic times. Low interest rates are making investments in buildings more attractive than alternative financial investments such as CD's. With activity in the new construction market at an all time low, savvy contractors are turning to the retrofit market - restoring, renovating and upgrading existing buildings. Heightened environmental concerns are fueling lighting incentive programs from the electric utilities and the EPA. Improvements in lighting technology are arriving in the marketplace at an accelerated rate. Building occupants are demanding higher quality workplaces and managers are seeking higher levels of productivity. Replacing older lighting equipment can substantially improve lighting efficiency, decrease energy and maintenance costs and, at the same time, improve the workplace by increasing lighting quality Lighting retrofit projects have a demonstrated track record, reducing lighting costs on the order of 50%. This experience can be applied to help structure retrofit projects. But, in order to reap all the benefits available from a retrofit project, it must be structured for success. The retrofit option introduces a unique series of issues for building owners, managers and engineers. The best way to prevent these issues from undermining the success of retrofit projects is to anticipate and completely plan for them. Successful retrofit projects run smoothER and stay within budgetary constraints. Three important considerations will guide the successful project: (1) Start comprehensive planning early, (2) Investigate existing conditions, and (3) Be sensitive to owner/occupants needs keep building operational

    Full Text Available Background. Tobacco smoking and its consequences are a serious public health problem in Romania. Evidence-based data on factors associated with successful smoking cessation are crucial to optimize tobacco control. The aim of the study was to determine the sociodemographic and other factors associated with smoking cessation success among adults. Materials and Methods. Data was from a sample of 4,517 individuals derived from the Global Adult Tobacco Survey (GATS. GATS is a cross-sectional, nationally representative household survey implemented in Romania in 2011. Data was analyzed with logistic regression. Results. Among females, the quit rate was 26.3% compared with 33.1% in males (P<0.02. We found disparities in cessation success among the analyzed groups of respondents. Being economically active, being aged 40 and above, and having an awareness of smoking health consequences were associated with long-term quitting smoking among men, while initiating smoking at a later age increased the odds of quitting smoking among women. However, cohabitation with nonsmokers was the strongest predictor of successful cessation among both genders. Conclusion. Programs increasing quit rates and encourage cessation among groups less likely to quit, adopting voluntary smoke-free homes, and increasing the awareness of smoking and tobacco pollution risks are needed.

    To identify predictors of successful external cephalic version (ECV) and to compare delivery outcome between women who had a successful ECV and women with spontaneous vertex presentation. A retrospective cohort study of all women who underwent ECV in a single tertiary medical center between 2007 and 2011. Delivery outcome was compared between women who underwent a trial of vaginal delivery following successful ECV with that of a control group in a 2:1 ratio. Multivariate analysis was used to identify predictors of successful ECV. Overall 287 were eligible for the study group. Of these 130 (45.3%) had a successful ECV. Polyhydramnios was the strongest factor associated with successful ECV (OR=3.1, 95%-CI 1.4-7.2), followed by transverse lie (versus breech presentation, OR=2.6, 95%-CI 1.2-6.7) and a posterior placenta (OR=1.7, 95%-CI 1.1-3.9), while nulliparity was associated with a lower likelihood of successful ECV (OR=0.4, 95%-CI 0.2-0.6). Women who had a successful ECV and underwent a trial of labor were more likely to deliver by operative vaginal delivery (OVD) (OR=1.8, 95%-CI 1.2-3.6), mainly due to a higher rate of prolonged 2nd, but were not at an increased risk for CS (OR=0.9, 95%-CI 0.4-2.4). Counselling to women prior to ECV should address the likelihood of success based on the predicting factors described above, as well as the increased risk for OVD in the case of successful ECV.

  4. Tracing the origins of success: implications for successful aging.

    Peterson, Nora M; Martin, Peter

    2015-02-01

    This paper addresses the debate about the use of the term "successful aging" from a humanistic, rather than behavioral, perspective. It attempts to uncover what success, a term frequently associated with aging, is: how can it be defined and when did it first come into use? In this paper, we draw from a number of humanistic perspectives, including the historical and linguistic, in order to explore the evolution of the term "success." We believe that words and concepts have deep implications for how concepts (such as aging) are culturally and historically perceived. We take a comparative approach, turning to the etymological roots of this term in British, French, and German literature. According to the earliest entries of the term in the Oxford English Dictionary, events can have good or bad success. Another definition marks success as outcome oriented. Often used in the context of war, religion, and medicine, the neutral, but often negative, use of "success" in literature of the Renaissance demonstrates the tensions that surround the word, and suggests that success is something to be approached carefully. Ignoring the ambiguous origins of success erases the fact that aging in earlier centuries echoes much of the same ambivalence with which many people discuss it today. Attending to the origins of success can help gerontologists understand the humanistic tradition behind their inquiry into what successful aging means today. © The Author 2014.

    Autonomous direct determination of a continuous time series of streamflow is not economically feasible at present (2014). As such, surrogates are used to derive a continuous time series of streamflow. The derivation process entails developing a streamflow rating, which can range from a simple, single-valued relation between stage and streamflow to a fully dynamic one-dimensional model based on hydraulics of the flow.

    Background Meniscal repair is performed in an attempt to prevent posttraumatic arthritis resulting from meniscal dysfunction after meniscal tears. The socioeconomic implications of premature arthritis are significant in the young patient population. Investigations and techniques focusing on meniscus preservation and healing are now at the forefront of orthopaedic sports medicine. Hypothesis Concomitant meniscal repair with ACL reconstruction is a durable and successful procedure at two year follow-up. Study Design Case Series; Level of evidence, 4. Methods All unilateral primary ACL reconstructions entered in 2002 in a prospective cohort who had meniscal repair at the time of ACLR were evaluated. Validated patient oriented outcome instruments were completed preoperatively and then again at the two-year postoperative time point. Reoperation after the index procedure was also documented and confirmed by operative reports. Results 437 unilateral primary ACL reconstructions were performed with 86 concomitant meniscal repairs (57 medial, 29 lateral) in 84 patients during the study period. Patient follow-up was obtained on 94% (81/86) of the meniscal repairs, allowing confirmation of meniscal repair success (defined as no repeat arthroscopic procedure) or failure. The overall success rate for meniscal repairs was 96% (76/79 patients) at two-year follow-up. Conclusions Meniscal repair is a successful procedure in conjunction with ACL reconstruction. When confronted with a “repairable” meniscal tear at the time of ACL reconstruction, orthopaedic surgeons can expect an estimated >90% clinical success rate at two-year follow-up using a variety of methods as shown in our study.

    1983-01-01

    The Bangladesh Social Marketing Project (SMP), providing contraceptives at an annual rate of 931,000 couple years of protection (CYP) as of June 1983, is a success. This figure has grown markedly since the start of the program in late 1975, when the SMP provided 80,000 CYPs, or 8% of nonclinical protection provided. The SMP has contributed to the steadily increasing national nonclinical contraceptive distribution. Currently, SMP distribution accounts for as much as the government and nongovernment programs combined. When clinical methods (including sterilizations) are added to national distribution, the SMP share represents about 28% of total contraceptive use. The SMP does not provide clinical methods, but the entire increase in nonclinical protection provided by the national program since 1975 has been the result of SMP product sales. The SMP utilizes the available mass media for promotion, including print, radio, television, as well as outdoor media and point of purchase materials. Mobile Film Units (MFUs) are an innovative promotional method employed by the SMP. Approximately 80 night time outdoor showings are organized each month in rural areas by SMP promoters. Typically, several short films, usually a popular story with a family planning theme, are run. Between each film the SMP products are of advertised. Products are often sold during and after the films. Retail outlets for SMP products include general stores, pharmacies, and other small shops. When products were introduced in 1975 retail outlets totaled 7500. By August 1983 the number of country wide retailers carrying SMP products had grown to nearly 100,000. In 1982 a marketing strategy emphasizing the role of doctors and rural medical practitioners (RMPs) was introduced. There are between 70,00-100,000 RMPs in Bangladesh. They are well known and respected "doctors" in their villages and add an extensive family planning outreach to the SMP system. The most important advantage of using the RMPs is their

    Research on successful aging at work has neglected contextual resources such as organizational climate, which refers to employees’ shared perceptions of their work environment. We introduce the construct of organizational climate for successful aging (OCSA) and examine it as a buffer of the negative relationship between employee age and focus on opportunities (i.e., beliefs about future goals and possibilities at work). Moreover, we expected that focus on opportunities, in turn, positively predicts job satisfaction, organizational commitment, and motivation to continue working after official retirement age. Data came from 649 employees working in 120 companies (Mage = 44 years, SD = 13). We controlled for organizational tenure, psychological climate for successful aging (i.e., individuals’ perceptions), and psychological and organizational age discrimination climate. Results of multilevel analyses supported our hypotheses. Overall, our findings suggest that OCSA is an important contextual resource for successful aging at work. PMID:27458405

    Biosphere reserves established under the UNESCO Man and the Biosphere Program aim to harmonise biodiversity conservation and sustainable development. Concerns over the extent to which the reserve network was living up to this ideal led to the development of a new strategy in 1995 (the Seville Strategy) to enhance the operation of the network of reserves. An evaluation of effectiveness of management of the biosphere reserve network was called for as part of this strategy. Expert opinion was assembled through a Delphi Process to identify successful and less successful reserves and investigate common factors influencing success or failure. Ninety biosphere reserves including sixty successful and thirty less successful reserves in 42 countries across all five Man and the Biosphere Program regions were identified. Most successful sites are the post-Seville generation while the majority of unsuccessful sites are pre-Seville that are managed as national parks and have not been amended to conform to the characteristics that are meant to define a biosphere reserve. Stakeholder participation and collaboration, governance, finance and resources, management, and awareness and communication are the most influential factors in the success or failure of the biosphere reserves. For success, the biosphere reserve concept needs to be clearly understood and applied through landscape zoning. Designated reserves then need a management system with inclusive good governance, strong participation and collaboration, adequate finance and human resource allocation and stable and responsible management and implementation. All rather obvious but it is difficult to achieve without commitment to the biosphere reserve concept by the governance authorities. Copyright © 2016 Elsevier Ltd. All rights reserved.

  11. The characteristics of successful entrepreneurs

    Directory of Open Access Journals (Sweden)

    Pokrajčić Dragana M.

    2004-01-01

    Full Text Available This paper examines the economic, psychological and social-behavioral theories of the entrepreneur in order to determine the characteristics of a successful entrepreneur. The major contribution of economic theories of the entrepreneur is better understanding of the entrepreneur and his/her role in economic development. The psychological characteristic theory of entrepreneur argues that successful entrepreneurs possess certain personality traits that mark them out as special, and tries to determine and to evaluate these special traits. The social-behavioral theories stress the influence of experience, knowledge, social environment and ability to learn on the entrepreneur’s success as well as his/her personality traits. Neither of the examined theories of entrepreneur gives a satisfactory explanation of the entrepreneur’s success, but taken as a whole, they can explain key factors of entrepreneur’s success. The entrepreneur’s success comes about as a result of his/her personality traits, ability to learn from experience and ability to adjust to his/her environment.

  12. TOWARDS UNDERSTANDING THE SUCCESSFUL LEARNER: A Case Study of IGNOU

    Full Text Available The growth of enrolment in the ODL system has been considerable. However, another parameter of significance in the context of Open and Distance learning is the learner success rate. While enrolment rates have been very encouraging in distance education, the pass-out rates haven’t been similar. There is a need to focus on the dynamics involved after a learner enrols himself in an OU and what drives him to stay focussed and complete his academic pursuit successfully or alternatively what holds or slows his academic progress and eventually makes him drop out. The study highlights that there are both institution-based (that is OU-based and learner-centric factors that could facilitate learners to successfully complete their studies. There are both controllable and uncontrollable factors that affect the OU learners’ success rate. This study attempts to capture the learner-centric factors and OU-related factors that have facilitated the learners to successfully complete their study. The paper delves into those key aspects or factors which would have facilitated the passed out learners in successfully completing their programmes in the open system. The findings are of direct interest, both from an institution perspective and that of a distance learner. It provides inputs to the Open and distance learning system, towards formulating appropriate strategies that further facilitate learners to successfully pass out. Also the findings serve as indicators/guide rules for any learner in the open system.

    Kutz, Mary N. Hill

    Scope and method of study. The purpose of the study was to examine the personal traits, skills, practices, behaviors, background, academic, and career success patterns of selected aviation leaders in Oklahoma. A purposive sample of 18 leaders who had achieved a top-ranked position of aviation leadership in an organization or a position of influence in the community was selected for interview. The leaders chosen for interview came from a variety of aviation organizations including government, academia, military, corporate aviation, and air carrier leadership as well as community leadership (specifically those aviation personnel who were engaged in a political or civic leadership role). Findings and conclusions. This study identified no common career choices, educational, family, or other background factors exclusively responsible for leadership success of all of the participants. Some of the more significant findings were that a high percentage of the leaders held undergraduate and advanced degrees; however, success had been achieved by some who had little or no college education. Aviation technical experience was not a prerequisite for aviation leadership success in that a significant number of the participants held no airman rating and some had entered positions of aviation leadership from non-aviation related careers. All had received some positive learning experience from their family background even those backgrounds which were less than desirable. All of the participants had been involved in volunteer civic or humanitarian leadership roles, and all had received numerous honors. The most frequently identified value expressed by the leaders was honesty; the predominant management style was participative with a strong backup style for directing, the most important skills were communication and listening skills, and the most frequently mentioned characteristics of success were honesty, credibility, vision, high standards, love for aviation and fiscal

    This chapter presents the basic principles of cluster dynamics as a particular case of mesoscopic rate theory models developed to investigate fuel behaviour under irradiation such as in UO 2 . It is shown that as this method simulates the evolution of the concentration of every type of point or aggregated defect in a grain of material. It produces rich information that sheds light on the mechanisms involved in microstructure evolution and gas behaviour that are not accessible through conventional models but yet can provide for improvements in those models. Cluster dynamics parameters are mainly the energetic values governing the basic evolution mechanisms of the material (diffusion, trapping and thermal resolution). In this sense, the model has a general applicability to very different operational situations (irradiation, ion-beam implantation, annealing) provided that they rely on the same basic mechanisms, without requiring additional data fitting, as is required for more empirical conventional models. This technique, when applied to krypton implanted and annealed samples, yields a precise interpretation of the release curves and helps assess migration mechanisms and the krypton diffusion coefficient, for which data is very difficult to obtain due to the low solubility of the gas.

  15. Wealth Accumulation and Factors Accounting for Success.

    Science.gov (United States)

    Pawasutipaisit, Anan; Townsend, Robert M

    2011-03-01

    We use detailed income, balance sheet, and cash flow statements constructed for households in a long monthly panel in an emerging market economy, and some recent contributions in economic theory, to document and better understand the factors underlying success in achieving upward mobility in the distribution of net worth. Wealth inequality is decreasing over time, and many households work their way out of poverty and lower wealth over the seven year period. The accounts establish that, mechanically, this is largely due to savings rather than incoming gifts and remittances. In turn, the growth of net worth can be decomposed household by household into the savings rate and how productively that savings is used, the return on assets (ROA). The latter plays the larger role. ROA is, in turn, positively correlated with higher education of household members, younger age of the head, and with a higher debt/asset ratio and lower initial wealth, so it seems from cross-sections that the financial system is imperfectly channeling resources to productive and poor households. Household fixed effects account for the larger part of ROA, and this success is largely persistent, undercutting the story that successful entrepreneurs are those that simply get lucky. Persistence does vary across households, and in at least one province with much change and increasing opportunities, ROA changes as households move over time to higher-return occupations. But for those households with high and persistent ROA, the savings rate is higher, consistent with some micro founded macro models with imperfect credit markets. Indeed, high ROA households save by investing in their own enterprises and adopt consistent financial strategies for smoothing fluctuations. More generally growth of wealth, savings levels and/or rates are correlated with TFP and the household fixed effects that are the larger part of ROA.

  16. Does pelvicaliceal system anatomy affect success of percutaneous nephrolithotomy?

    To investigate the effect of the pelvicaliceal system (PCS) anatomy on the percutaneous nephrolithotomy (PCNL) success rate. Although the caliceal anatomy is effective for stone clearance after shock wave lithotripsy and retrograde intrarenal lithotripsy, the effect of the caliceal anatomy after PCNL has not been evaluated to date. A total of 498 patients who had undergone PCNL and preoperative intravenous urography were enrolled in our study. Kidney-related anatomic factors, such as the PCS surface area and type, degree of hydronephrosis, infundibulopelvic angle, upper-lower calix angle, infundibular length, and infundibular width were calculated using intravenous urography. The association between the PCNL success rate and kidney-related anatomic factors was retrospectively analyzed using chi-square tests, Fisher's exact test, Mann-Whitney U test, and forward stepwise regression analysis. A success rate of 78.1% was achieved. No difference was seen the success rates among the PCS types. The mean PCS surface area was 20.1 ± 9.7 cm(2) in patients with successful outcomes and 24.5 ± 10.2 cm(2) in patients with remaining stones (P = .001). The mean infundibulopelvic angle, upper-lower calix angle, infundibular length, and infundibular width were similar in both groups. Multivariate binary logistic regression analysis showed that stone configuration and PCS surface area were independent factors affecting the PCNL success rates. The results of our study have shown that the PCS surface area is the only anatomic factor that affects the PCNL success rate and patients with a PCS surface area <20.5 cm(2) have greater PCNL success.

    To analyze the prognostic factors that are associated with the success, survival, and failure rates of dental implants. Data including implant sizes, insertion time, implant location, and prosthetic treatment of 1656 implants have been collected, and the association of these factors with success, survival, and failure of implants was analyzed. The success rate was lower for short and maxillary implants. The failure rate of maxillary implants exceeded that of mandibular implants, and the failure rate of implants that were placed in the maxillary anterior region was significantly higher than other regions. The failure rates of implants that were placed 5 years ago or more were higher than those that were placed later. Anterior maxilla is more critical for implant loss than other sites. Implants in the anterior mandible show better success compared with other locations, and longer implants show better success rates. The learning curve of the clinician influences survival and success rates of dental implants.

  19. Exceptional Antibodies Produced by Successive Immunizations.

    Directory of Open Access Journals (Sweden)

    Patricia J Gearhart

    2015-12-01

    Full Text Available Antibodies stand between us and pathogens. Viruses mutate quickly to avoid detection, and antibodies mutate at similar rates to hunt them down. This death spiral is fueled by specialized proteins and error-prone polymerases that change DNA sequences. Here, we explore how B lymphocytes stay in the race by expressing activation-induced deaminase, which unleashes a tsunami of mutations in the immunoglobulin loci. This produces random DNA substitutions, followed by selection for the highest affinity antibodies. We may be able to manipulate the process to produce better antibodies by expanding the repertoire of specific B cells through successive vaccinations.

    Universities in the U.S. have a significant impact on business through the transfer of technology. This paper describes goals and philosophy of the Technology Licensing Office at the Massachusetts Institute of Technology. This paper also relates the critical factors for susscessful technology transfer, particularly relating to new business formation. These critical factors include the quality of the technology, the quality of the management, the quality of the investor, the passion for success, and the image of the company. Descriptions of three different levels of investment are also given and the most successful level of investment for starting a new company is reviewed. Licensing to large companies is also briefly reviewed, as this type of licensing requires some different strategies than that of licensing to start-up companies. High quality critical factors and intelligent investment create rewards for the parties and successful ventures.

  2. Succession planning: a call to action for nurse executives.

    2013-10-01

    To discuss the organisational benefits of strategic succession planning in acute care hospital settings as a responsibility of chief nurse executives. A formal succession planning process is crucial to the financial and operational viability and sustainability of acute care hospitals. A succession plan is an essential business strategy that promotes effective leadership transition and continuity while maintaining productivity. Nursing and business literature were reviewed; reports contrasting institutions with and without succession plans were examined; and, operational implications were considered. It is imperative that chief nurse executives respond to the business benefits of an effective succession planning programme, identify common barriers and solutions, and implement best practices for a successful strategic succession planning programme. A strategic succession planning programme may offer many benefits to an acute care hospital, including improved retention rates, increased staff engagement and enhanced financial performance. Considering the ageing nursing workforce and the potential increase in demand for nursing services in the near future, nurse executives and other nurse leaders must actively engage in a formal succession planning process. A formal succession planning programme will help to provide strategic leadership continuity, operational effectiveness and improved quality of care. © 2013 John Wiley & Sons Ltd.

  3. Higher survival drives the success of nitrogen-fixing trees through succession in Costa Rican rainforests.

    Menge, Duncan N L; Chazdon, Robin L

    2016-02-01

    Trees capable of symbiotic nitrogen (N) fixation ('N fixers') are abundant in many tropical forests. In temperate forests, it is well known that N fixers specialize in early-successional niches, but in tropical forests, successional trends of N-fixing species are poorly understood. We used a long-term census study (1997-2013) of regenerating lowland wet tropical forests in Costa Rica to document successional patterns of N fixers vs non-fixers, and used an individual-based model to determine the demographic drivers of these trends. N fixers increased in relative basal area during succession. In the youngest forests, N fixers grew 2.5 times faster, recruited at a similar rate and were 15 times less likely to die as non-fixers. As succession proceeded, the growth and survival disparities decreased, whereas N fixer recruitment decreased relative to non-fixers. According to our individual-based model, high survival was the dominant driver of the increase in basal area of N fixers. Our data suggest that N fixers are successful throughout secondary succession in tropical rainforests of north-east Costa Rica, and that attempts to understand this success should focus on tree survival. © 2015 The Authors.

    Full Text Available The illusion of control refers to the inference of action-outcome contingency in situations where outcomes are in fact random. The strength of this illusion has been found to be affected by whether the frequency of successes increases or decreases over repeated trials, in what can be termed a ``success-slope'' effect. Previous studies have generated inconsistent findings regarding the nature of this effect. In this paper we present an experiment (N = 334 that overcomes several methodological limitations within this literature, employing a wider range of dependent measures (measures of two different types of illusory control, primary (by self and secondary (by luck, as well as measures of remembered success-frequency. Results indicate that different dependent measures lead to different effects. On measures of (primary, but not secondary control over the task, scores were highest when the rate of success increased over time. Meanwhile, estimates of success-frequency in the task did not vary across conditions and showed trends consistent with the broader literature on human memory.

    Full Text Available There is a wide body of evidence showing a significant increase in the adoption of mergers and acquisitions (M&A worldwide. Moreover, research confirms that the integration and implementation stage (post-M&A has a major impact on the success or failure of a merger or acquisition. Therefore it has become increasingly important to explore the post-M&A phase further in order to support the management teams of organizations pursuing a merger or acquisition in meeting all their desired objectives. This paper proposes a framework to help in the successful execution of M&A. The framework contains three main elements: the motives, success factors and key success indicators (KSI. A qualitative research approach using the multiple case study methodology was conducted to test the framework. Ten case studies were selected from the industrial sector in Egypt and used to validate the research. The final version of the M&A framework was provided after applying the research results. Considering the practical implications of the M&A framework, a tool was proposed for its application in light of the balanced scorecard (BSC methodology. The proposed M&A scorecard tool should be used in the strategic planning and execution of M&A. Both the proposed M&A framework and the M&A scorecard tool should be used to guide the implementation of M&A in order to increase the success rate enjoyed by organizations.

    Gemini Observatory has been very successful at attracting, hiring and retaining female Scientists. We present data on the growth of the scientific staff since the start of the Observatory, and science fellow recruiting from 2006-2008. At Gemini 31% of the Science Staff holding PhDs are female compared with 13.9% within the United States. The Science Management is 75% female, as is 50% of the Gemini Directorate. This critical mass of female representation within the science staff and management appears to have had a positive effect on female recruitment and hiring. The science fellow recruitment during the past 3 years has attracted 21-38% female applicants and 57% of new hires during this period have been female scientists. Perhaps even more significant, the retention rate of female science staff at Gemini is 88%, compared to 64% for male science staff. There are likely many factors that contribute to this success, but the conclusion is that Gemini has earned a reputation in the scientific community as a place where female scientists are valued and can be successful.

    Tracheal intubation (TI) is a lifesaving critical care skill. Failed TI attempts, however, can harm patients. Critical care transport (CCT) teams function as the first point of critical care contact for patients being transported to tertiary medical centers for specialized surgical, medical, and trauma care. The Ground and Air Medical qUality in Transport (GAMUT) Quality Improvement Collaborative uses a quality metric database to track CCT quality metric performance, including TI. We sought to describe TI among GAMUT participants with the hypothesis that CCT would perform better than other prehospital TI reports and similarly to hospital TI success. The GAMUT Database is a global, voluntary database for tracking consensus quality metric performance among CCT programs performing neonatal, pediatric, and adult transports. The TI-specific quality metrics are "first attempt TI success" and "definitive airway sans hypoxia/hypotension on first attempt (DASH-1A)." The 2015 GAMUT Database was queried and analysis included patient age, program type, and intubation success rate. Analysis included simple statistics and Pearson chi-square with Bonferroni-adjusted post hoc z tests (significance = p success was lowest in neonates (59.3%, 617 attempts), better in pediatrics (81.7%, 519 attempts), and best in adults (87%, 2900 attempts), p success versus pediatric- and neonatal-focused teams (86.9% vs. 63.5%, p success (86.5% vs. 75.3%, p success are higher in adult patients and adult-focused CCT teams. TI success rates are higher in CCT than other prehospital settings, but lower than in-hospital success TI rates. Identifying factors influencing TI success among high performers should influence best practice strategies for TI.

    2012-02-01

    Full Text Available In this note we illustrate and develop further with mathematics and examples, the work on successive standardization (or normalization that is studied earlier by the same authors in [1] and [2]. Thus, we deal with successive iterations applied to rectangular arrays of numbers, where to avoid technical difficulties an array has at least three rows and at least three columns. Without loss, an iteration begins with operations on columns: first subtract the mean of each column; then divide by its standard deviation. The iteration continues with the same two operations done successively for rows. These four operations applied in sequence completes one iteration. One then iterates again, and again, and again, ... In [1] it was argued that if arrays are made up of real numbers, then the set for which convergence of these successive iterations fails has Lebesgue measure 0. The limiting array has row and column means 0, row and column standard deviations 1. A basic result on convergence given in [1] is true, though the argument in [1] is faulty. The result is stated in the form of a theorem here, and the argument for the theorem is correct. Moreover, many graphics given in [1] suggest that except for a set of entries of any array with Lebesgue measure 0, convergence is very rapid, eventually exponentially fast in the number of iterations. Because we learned this set of rules from Bradley Efron, we call it “Efron’s algorithm”. More importantly, the rapidity of convergence is illustrated by numerical examples.

  18. Duplicating Research Success at Xerox

    Science.gov (United States)

    Hays, Dan A.

    2003-03-01

    The genesis of Xerox is rooted in the invention of xerography by physicist Chester Carlson in 1938. The initial research by Carlson can be viewed as the first of four successful xerographic research eras that have contributed to the growth of Xerox. The second era began in 1944 when Carlson established a working relationship with Battelle Memorial Institute in Columbus, OH. Due to many research advances at Battelle, the Haloid Corporation in Rochester, NY acquired a license to the xerographic process in 1947. The name of the company was changed to Xerox Corporation in 1961 following the wide market acceptance of the legendary Xerox 914 copier. Rapid revenue growth of Xerox in the mid-'60s provided the foundation for a third successful research era in the '70s and '80s. A research center was established in Webster, NY for the purpose of improving the design of xerographic subsystems and materials. These research efforts contributed to the commercial success of the DocuTech family of digital production printers. The fourth successful research era was initiated in the '90s with the objective of identifying a high-speed color xerographic printing process. A number of research advances contributed to the design of a 100 page per minute printer recently introduced as the Xerox DocuColor iGen3 Digital Production Press. To illustrate the role of research in enabling these waves of successful xerographic products, the physics of photoreceptors, light exposure and development subsystems will be discussed. Since the annual worldwide revenue of the xerographic industry exceeds 100 billion dollars, the economic return on Carlson's initial research investment in the mid-'30s is astronomical. The future for xerography remains promising since the technology enables high-speed digital printing of high-quality color documents with variable information.

  19. Ending the CEO succession crisis.

    Science.gov (United States)

    Charan, Ram

    2005-02-01

    The CEO succession process is broken. Many companies have no meaningful succession plans, and few of the ones that do are happy with them. CEO tenure is shrinking; in fact, two out of five CEOs fail in their first 18 months. It isn't just that more CEOs are being replaced; it's that they're being replaced badly. The problems extend to every aspect of CEO succession: internal development programs, board supervision, and outside recruitment. While many organizations do a decent job of nurturing middle managers, few have set up the comprehensive programs needed to find the half-dozen true CEO candidates out of the thousands of leaders in their midst. Even more damaging is the failure of boards to devote enough attention to succession. Search committee members often have no experience hiring CEOs; lacking guidance, they supply either the narrowest or the most general of requirements and then fail to vet eitherthe candidates or the recruiters. The result is that too often new CEOs are plucked from the well-worn Rolodexes of a remarkably small number of recruiters. These candidates may be strong in charisma but may lack critical skills or otherwise be a bad fit with the company. The resulting high turnover is particularly damaging, since outside CEOs often bring in their own teams, can cause the company to lose focus, and are especially costly to be rid of. Drawing on over 35 years of experience with CEO succession, the author explains how companies can create a deep pool of internal candidates, how boards can consistently align strategy and leadership development, and how directors can get their money's worth from recruiters. Choosing a CEO should be not one decision but an amalgam ofthousands of decisions made by many people every day over years.

    The aim of this study was to establish predictors for successfully planned extubation, which can be followed by medical personnel. The patients who were admitted to the adult intensive care unit of a tertiary hospital and met the following criteria between January 2005 and December 2014 were collected retrospectively: intubation > 48 hours; and candidate for extubation. The patient characteristics, including disease severity, rapid shallow breath index (RSBI), maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), cuff leak test (CLT) before extubation, and outcome, were recorded. The CLT was classified as 2+ with audible flow without a stethoscope, 1+ with audible flow using a stethoscope, and negative (N) with no audible flow, even with a stethoscope. Failure to extubate was defined as reintubation within 48 hours. In total, 6583 patients were enrolled and 403 patients (6.1%) had extubation failures. Male patients dominated the patient cohort (4261 [64.7%]). The mean age was 64.5±16.3 years. The overall in-hospital mortality rate was 11.3%. The extubation failure rate for females was greater than males (7.7% vs 5.3%, P respiratory capacity, was developed to better predict extubation success.

  1. Modeling student success in engineering education

    Jin, Qu

    In order for the United States to maintain its global competitiveness, the long-term success of our engineering students in specific courses, programs, and colleges is now, more than ever, an extremely high priority. Numerous studies have focused on factors that impact student success, namely academic performance, retention, and/or graduation. However, there are only a limited number of works that have systematically developed models to investigate important factors and to predict student success in engineering. Therefore, this research presents three separate but highly connected investigations to address this gap. The first investigation involves explaining and predicting engineering students' success in Calculus I courses using statistical models. The participants were more than 4000 first-year engineering students (cohort years 2004 - 2008) who enrolled in Calculus I courses during the first semester in a large Midwestern university. Predictions from statistical models were proposed to be used to place engineering students into calculus courses. The success rates were improved by 12% in Calculus IA using predictions from models developed over traditional placement method. The results showed that these statistical models provided a more accurate calculus placement method than traditional placement methods and help improve success rates in those courses. In the second investigation, multi-outcome and single-outcome neural network models were designed to understand and to predict first-year retention and first-year GPA of engineering students. The participants were more than 3000 first year engineering students (cohort years 2004 - 2005) enrolled in a large Midwestern university. The independent variables include both high school academic performance factors and affective factors measured prior to entry. The prediction performances of the multi-outcome and single-outcome models were comparable. The ability to predict cumulative GPA at the end of an engineering

    Intra-abdominal testes can be treated with several surgical procedures. We evaluated factors influencing the outcome of orchiopexy for intra-abdominal testis. We retrospectively reviewed 156 consecutive orchiopexies performed for intra-abdominal testis, defined as a nonpalpable testis on examination and located in the abdomen at surgery. All surgical approaches were included in the study. Primary outcome was the overall success rate and secondary outcomes were success based on surgical approach, age and a patent processus vaginalis. Success was considered a testis with normal texture and size compared to the contralateral testis at followup. Multivariate analysis was performed to determine factors predictive of success. The overall success rate of all orchiopexies was 79.5%. Median patient age at orchiopexy was 12 months and mean followup was 16 months. Of the patients 117 had a patent processus vaginalis at surgery. One-stage abdominal orchiopexy was performed in 92 testes with 89.1% success. Of these cases 32 were performed laparoscopically with 96.9% success. One-stage Fowler-Stephens orchiopexy was performed in 27 testes and 2-stage Fowler-Stephens orchiopexy was performed in 37 with success in 63.0% and 67.6%, respectively. Multivariate analysis revealed that 1-stage orchiopexy without vessel division had more successful outcomes than 1 and 2-stage Fowler-Stephens orchiopexy (OR 0.24, p = 0.007 and 0.29, p = 0.19, respectively). Neither age at surgery nor an open internal ring was significant (p = 0.49 and 0.12, respectively). The overall success of orchiopexy for intra-abdominal testis is 79.5%. While patient selection remains a critical factor, 1-stage orchiopexy without vessel division was significantly more successful and a laparoscopic approach was associated with the fewest failures for intra-abdominal testes.

    Full Text Available This paper looks at the important elements of language learning and teaching i.e. the role of teachers as well as the attitude and motivation of learners. Teachers undoubtedly play crucial roles in students’ language learning outcome which could ignite or diminish students’ motivation. Positive attitudes and motivation – instrumental or integrative and intrinsic or extrinsic – are key to successful learning. Therefore it is paramount for language teachers as well as learners to know these roles and nurture the best possible ways where language teaching and learning will thrive. This paper also suggested that both stake-holders should be open to holistic approach of language learning and that other factors such as the environment could play an important part in language teaching and learning success.

    Focal cartilage lesions are a cause of long-term disability and morbidity. After cartilage repair, it is crucial to evaluate long-term progression or failure in a reproducible, standardized manner. This article provides an overview of the different cartilage repair procedures and important characteristics to look for in cartilage repair imaging. Specifics and pitfalls are pointed out alongside general aspects. After successful cartilage repair, a complete, but not hypertrophic filling of the defect is the primary criterion of treatment success. The repair tissue should also be completely integrated to the surrounding native cartilage. After some months, the transplants signal should be isointense compared to native cartilage. Complications like osteophytes, subchondral defects, cysts, adhesion and chronic bone marrow edema or joint effusion are common and have to be observed via follow-up. Radiological evaluation and interpretation of postoperative changes should always take the repair method into account. (orig.) [de

Many businesses do not survive because business owners fail to develop an effective plan. 2. The business plan focuses on major areas of concern and their contribution to the success of a new business. The finished product communicates the product/service to others and provides the basis for the financial proposal. 3. Planning helps identify customers, market area, pricing strategy, and competitive conditions. It aids in decision making and is an essential guide for operating a business successfully and measuring progress. 4. The business plan not only serves as a mechanism for obtaining any needed financial resources, but also indicates the future direction of the company.

Through comparison and quantitative observations, and by focusing on the success of prose rather than its invention, it is shown that in all four cases two...... reading aloud) has been underplayed in previous scholarship mostly focused on authorial choices and invention. For two of the literatures (Greek, French) the fast dynamics of the rise of prose has already been identified and discussed, but for the two others (Latin, Old Norse), the observation is new....... It is also suggested that the exactly contemporary rise of French and Old Norse prose (c. 1200-1230) most probably is connected. The four literatures are each shown in chronological charts so as to visualize the timeline and the relation between poetic and prosaic works. The article furthermore reflects...

    A first success for the anti-nuclear movement emerges: the Czechoslovakian government renounces of blocks 3 and 4, 1000 MW each, in Temelin. Although lack of money is admitted as a partial cause, the main cause is the broad opposition of the population, especially in Austria, says the author. Therefore the author appeals to the coworkers to double their efforts in the signature collection against Temelin. The slogan is: we shall make Temelin too. (qui)

  14. Success in Transdisciplinary Sustainability Research

    Directory of Open Access Journals (Sweden)

    Tobias Luthe

    2017-01-01

    Full Text Available The complexity of sustainable development and societal transitions require both analytical understandings of how coupled human-environment systems function and transdisciplinary science-to-practice approaches. The academic discourse has advanced in developing a framework for defining success in transdisciplinary research (TDR. Further empirical evidence is needed to validate the proposed concepts with TDR case studies. This paper applies a widely used TDR framework to test and critically evaluate its design principles and criteria of success with five TDR case studies the author is intimately familiar with. Overall, the design principles of the framework are validated for the five cases. Additional design principles are derived from the case analysis and proposed to complement the applied framework: (1 A project origin from society as opposed to with and for society; (2 Quickly available initiation funding; (3 Flexibility in time, objectives and methods throughout the research process; (4 Acceptance of process vs. project results; (5 Inclusion of public science communication; and (6 A demand-driven transition to a prolonged or new project partnership. The complementing principles are proposed for integration in the applied framework and are subject to further empirical testing. The reflexive empirical approach I have taken in this paper offers a key step towards removing institutional barriers for successful TDR, demonstrating how conceptual frameworks can be applied.

    2016-12-01

    In the past decade, efforts to communicate the facts of global change have not successfully moved political leaders and the general public to action. In response, a number of collaborative efforts between scientists and professional communicators, writers, journalists, bloggers, filmmakers, artists and others have arisen seeking to bridge that gap. As a result, a new cadre of science-literate communicators, and media-savvy scientists have made themselves visible across diverse mainstream, traditional, and social media outlets. Because of these collaborations, in recent years, misinformation, and disinformation have been successfully met with accurate and credible rebuttals within a single news cycle.Examples of these efforts is the Dark Snow Project, a science/communication collaboration focusing initially on accelerated arctic melt and sea level rise, and the Climate Science Rapid Response team, which matches professional journalists with appropriate science experts in order to respond within a single news cycle to misinformation or misunderstandings about climate science.The session will discuss successful examples and suggest creative approaches for the future.

    We report our experience with Guenter Tulip filter placement indications, retrievals, and procedural problems, with emphasis on alternative retrieval techniques. We have identified 92 consecutive patients in whom a Guenter Tulip filter was placed and filter removal attempted. We recorded patient demographic information, filter placement and retrieval indications, procedures, standard and nonstandard filter retrieval techniques, complications, and clinical outcomes. The mean time to retrieval for those who experienced filter strut penetration was statistically significant [F(1,90) = 8.55, p = 0.004]. Filter strut(s) IVC penetration and successful retrieval were found to be statistically significant (p = 0.043). The filter hook-IVC relationship correlated with successful retrieval. A modified guidewire loop technique was applied in 8 of 10 cases where the hook appeared to penetrate the IVC wall and could not be engaged with a loop snare catheter, providing additional technical success in 6 of 8 (75%). Therefore, the total filter retrieval success increased from 88 to 95%. In conclusion, the Guenter Tulip filter has high successful retrieval rates with low rates of complication. Additional maneuvers such as a guidewire loop method can be used to improve retrieval success rates when the filter hook is endothelialized.

    The geoscience student population in the United States today does not reflect the diversity of the US population. Not only does this challenge our ability to educate sufficient numbers of students in the geosciences, it also challenges our ability to address issues of environmental justice, to bring geoscience expertise to diverse communities, and to pursue a research agenda reflecting the needs and interests of our nation as a whole. Programs that are successful in supporting students from underrepresented groups attend to the whole student (Jolly et al, 2004) as they develop not only knowledge and skills, but a sense of belonging and a drive to succeed in geoscience. The whole student approach provides a framework for supporting the success of all students, be they members of underrepresented groups or not. Important aspects of support include mentoring and advising, academic support, an inclusive learning community, and opportunities to learn about the profession and to develop geoscience and professional skills. To successfully provide support for the full range of students, it is critical to consider not only what opportunities are available but the barriers different types of students face in accessing these opportunities. Barriers may arise from gaps in academic experiences, crossing into a new and unfamiliar culture, lack of confidence, stereotype threat, implicit bias and other sources. Isolation of geoscience learning from its application and social context may preferentially discourage some groups. Action can be taken to increase support for all students within an individual course, a department or an institution. The InTeGrate STEP Center for the Geosciences, the Supporting and Advancing Geoscience Education at Two-Year Colleges program and the On the Cutting Edge Professional Development for Geoscience Faculty program all provide resources for individuals and departments including on line information, program descriptions, and workshop opportunities.

    A key success of the decommissioning effort at the National Aeronautics and Space Administration's (NASA's) Plum Brook Reactor Facility (PBRF) has been the public outreach program. The approach has been based on risk communications rather than a public relations approach. As a result it has kept the public feeling more involved in the process. It ensures they have the information needed to understand the project and its goals, and to make recommendations. All this is done so that NASA can better plan and execute the necessary work without delays or suprises.

    Full Text Available The Political Economy and Public Choice approaches have promoted the study of interactions between the economy and the polity for over 60 years now. The present paper endeavours to provide a critical discussion of this literature and its achievements. In particular, it begins with the different approaches based on empirically tested or politometric models and it then proceeds to discuss different studies of the effects that particular rules of the game have on politico-economic outcomes. The third section of the paper will address studies that take institutions to be endogenous and aims to explain why particular institutions emerge. Finally, the question of whether Political Economy has been a success or a failure will be tackled. While the success in terms of the position it has gained in economic research and teaching is undeniable, a look at one of the most thriving recent areas of economics, happiness research, will reveal that some of its fundamental lessons are all too often disregarded.

    The past year proved a successful one for Neste Corporation. Profitability was good and operations were consistently developed. Neste is committed to giving high priority to productivity and know- how to ensure that this success continues into the future. Important developments affecting the structure of Neste Corporation during 1990 included the amalgamation of Neste's oil-related activities into a single division, the increasing concentration of Neste Chemicals, activities in Central and Southern Europe and a major strengthening of oil exploration and production operations. Neste Oil turned in a good result during 1990. Neste imported a total of 8.9 million tonnes of crude oil during 1990. Imports from the Soviet Union at 5.2 million tonnes, were over 2 million tonnes less than planned. Some 2.5 million tonnes were imported from the North Sea, and 1.2 million tonnes from the Middle East. The year was one of expansion, diversification, and solid profit for Neste Chemicals. Net sales grew by 18 % compared to 1989 and the division recorded a satisfactory performance. Petrochemicals and polyolefins production increased suhstantially as a result of plants completed, acquired, or leased during 1989. The gas division's net sales during 1990 were 46 % higher than during 1989. This growth largely resulted from an increase in the consumption of natural gas and an expansion in the volume of international IPG business. The division's profitability remained satisfactory

    Learning during skills-based psychosocial treatments for schizophrenia is influenced by the motivating properties of the treatment context and the motivational orientation of the client. Given that motivational impairment is a core feature of schizophrenia with significant functional implications, intervention strategies emphasizing extrinsic and/or intrinsic goals may be prescribed to enhance skill learning and treatment outcomes. The purpose of this article is to consider the role that motivation plays in treatment success by evaluating the relationship between motivation and learning during cognitive remediation for schizophrenia. As intrinsic motivation (IM) is most often associated with learning, we will integrate research findings which address 3 main questions: (1) is IM in schizophrenia static or dynamic, (2) is it possible to manipulate the state of being intrinsically motivated and if so do manipulations of IM affect learning? and (3) can motivation theory be translated into clinical practice? This knowledge can facilitate treatment strategies to address the low base rate of IM that is characteristic of schizophrenia and can be applied to cognitive remediation as well as other psychosocial interventions which require learning for treatment success.

    Reduced competition is a frequent explanation for the success of many introduced species. In benthic marine biofouling communities, space limitation leads to high rates of overgrowth competition. Some species can utilise other living organisms as substrate (epibiosis), proffering a competitive advantage for the epibiont. Additionally, some species can prevent or reduce epibiotic settlement on their surfaces and avoid being basibionts. To test whether epibiotic pressure differs between native and introduced species, we undertook ex situ experiments comparing bryozoan larval settlement to determine if introduced species demonstrate a greater propensity to settle as epibionts, and a reduced propensity to be basibionts, than native species. Here we report that introduced species opportunistically settle on any space (bare, native, or introduced), whereas native species exhibit a strong tendency to settle on and near other natives, but avoid settling on or near introduced basibionts. In addition, larvae of native species experience greater larval wastage (mortality) than introduced species, both in the presence and absence of living substrates. Introduced species' ability to settle on natives as epibionts, and in turn avoid epibiosis as basibionts, combined with significantly enhanced native larval wastage, provides a comprehensive suite of competitive advantages contributing to the invasion success of these biofouling species.

    2011-01-01

    Since the beginning of this year, no fewer than six new EU projects at CERN have been launched. These are just a third of the projects selected by the European Commission for funding during the course of 2010, bringing in some 23 M€ over a period of two to five years. This makes last year our most successful yet in securing EU support, and places CERN among the top 50 out of more than 10,000 participants in the EU’s seventh Framework Programme.   The success rate of our proposals has been very good ever since the beginning of FP7 in 2007, particularly for projects coordinated by CERN. There has been a clear evolution of CERN’s involvement in EU projects over the last 10 years. In the early days, we tended to target the Marie Curie actions and the e-Infrastructures Programme. The former help us to fulfil our mission to train young people, while the latter supported the development of the European Grid, mainly through the EGEE projects. Later, the Organization became a...

    The backlash avoidance model (BAM) suggests women insufficiently self-promote because they fear backlash for behavior which is incongruent with traditional gender roles. Avoiding self-promoting behavior is also potentially related to associating success with negative consequences. In two studies we tested whether self-promotion and fear of success will be predictors of lower salaries and anticipation of lower chances of success in an exam. In study 1, prior to the exam they were about to take, we asked 234 students about their predictions concerning exam results and their future earnings. They also filled scales measuring their associations with success (fear of success) and tendency for self-promotion. The tested model proved that in comparison to men, women expect lower salaries in the future, anticipate lower test performance and associate success with more negative consequences. Both tendency for self-promotion and fear of success are related to anticipation of success in test performance and expectations concerning future earnings. In study 2 we repeated the procedure on a sample of younger female and male high school pupils (N = 100) to verify whether associating success with negative consequences and differences in self-promotion strategies are observable in a younger demographic. Our results show that girls and boys in high school do not differ with regard to fear of success, self-promotion or agency levels. Girls and boys anticipated to obtain similar results in math exam results, but girls expected to have higher results in language exams. Nevertheless, school pupils also differed regarding their future earnings but only in the short term. Fear of success and agency self-ratings were significant predictors of expectations concerning future earnings, but only among high school boys and with regard to earnings expected just after graduation.

    Functional magnetic resonance imaging (fMRI) is frequently used in the presurgical diagnostic procedure of epilepsy patients, in particular for lateralization of speech and memory and for localization of the primary motor cortex to delineate the epileptogenic lesion from eloquent brain areas. fMRI is one of the non-invasive procedures in the presurgical diagnostic process, together with medical history, seizure semiology, neurological examination, interictal and ictal EEG, structural MRI, video EEG monitoring and neuropsychology. This diagnostic sequence leads either to the decision for or against elective epilepsy surgery or to the decision to proceed with invasive diagnostic techniques (Wada test, intra-operative or extra-operative cortical stimulation). It is difficult to evaluate the contribution of the fMRI test in isolation to the validity of the entire diagnostic sequence. Complications such as memory loss and aphasia in temporal lobe resections or paresis after frontal lobe resections are rare and rarely of disastrous extent. This further complicates the evaluation of the clinical relevance of fMRI as a predictive tool. In this article studies which investigated the concordance between fMRI and other diagnostic gold standards will be presented as well as the association between presurgical fMRI and postsurgical morbidity. (orig.) [German] Die funktionelle Magnetresonanztomographie (fMRT) wird im Rahmen der Epilepsiediagnostik vor epilepsiechirurgischen Eingriffen insbesondere zur Lateralisation von Sprache und Gedaechtnis und zur Lokalisation der Zentralregion eingesetzt, um den eloquenten Kortex von der epilepsieverursachenden, chirurgisch zugaenglichen Laesion abzugrenzen. Dabei ist die fMRT Teil einer Sequenz nichtinvasiver klinischer Tests (Anamnese, Anfall-Semiologie, neurologischer Status, interiktales und iktales EEG, strukturelles MRT, Video-EEG-Monitoring, Neuropsychologie). Das Ergebnis dieser Sequenz ist die Entscheidung fuer oder gegen einen elektiven epilepsiechirurgischen Eingriff bzw. fuer oder gegen weitere invasive Diagnostik (Wada-Test, intra- oder extraoperative kortikale Stimulation). Komplikationen epilepsiechirurgischer Eingriffe, z. B. Minderungen des Gedaechtnisses oder der Benennleistung nach Temporallappenresektion bzw. aphasische Stoerungen und Paresen nach Frontallappenresektion, sind selten und selten von katastrophalem Ausmass, was eine Standortbestimmung fuer das klinische fMRT erschwert. In diesem Artikel werden daher Studien vorgestellt, die die Uebereinstimmung zwischen fMRT und anderen ''Goldstandards'' oder postoperativer Morbiditaet untersucht haben. (orig.)

    The incidence of chronic pancreatitis is increasing in industrialized countries due to the steady increase of alcohol abuse. The pathogenesis of this disease is still incompletely understood. A cure is not possible. The knowledge of the patients history and a thorough clinical investigation together with the availability of a wide array of laboratory tests and imaging procedures enable the physician to characterize the stage of the disease. Exact knowledge of the present pancreatic morphology, potential complications of the disease, and knowledge about the present exocrine and endocrine function capacity are prerequisites for adequate therapeutic decision making. The therapeutic possibilities include termination of alcohol abuse, various options of treatment of pain according to the various pathogenetic possibilities leading to pain, pancreatic digestive enzyme supplementation, treatment of diabetes, and either endoscopic or surgical treatments of complications of the disease. (orig.) [Deutsch] Die Inzidenz der chronischen Pankreatitis nimmt in den Industrienationen aufgrund der Zunahme des Alkoholabusus an Haeufigkeit zu.

    In chronic pulmonary embolism branches of the pulmonary arterial tree remain partially or totally occluded. This may lead to pulmonary hypertension with the development of right ventricular hypertrophy as well as structural changes of pulmonary arteries. Imaging of chronic pulmonary embolism should prove vessel occlusions (pulmonary angiography, MSCT, MRI) and reduction of regional lung perfusion (lung scanning, MSCT, MRI). According to current guidelines ventilation-perfusion lung scanning and pulmonary angiography are still recommended as the methods of choice. MSCT and MRI provide technical alternatives which are helpful in differential diagnosis versus other types of pulmonary hypertension. In spite of medical and surgical measures (in rare cases pulmonary thromboendarterectomy) the prognosis of chronic pulmonary embolism remains unfavourable. (orig.) [German] Bei der chronischen Lungenembolie sind Abschnitte der arteriellen Lungenstrombahn dauerhaft verschlossen.

    The low level of public understanding of energy in general, and nuclear energy in particular in the United States is well known, especially by the world's scientific community. A technologically leading nation such as the United States, will not remain so for long, if fear, anxiety, worry, anger, and technological misinformation continue to influence if not drive science and energy policy. Our society, our freedom, and even our national security are at risk when sound science and energy policies are inhibited or prevented. As a scientific organization, the American Nuclear Society believes that it is our responsibility, not merely an obligation, to get involved with the educational processes of our nation. Through the Public Information Committee of ANS a variety of educational activities have been undertaken, with remarkable success. This presentation describes some of these and some of the many lessons learned from these activities and about ourselves

The “minimal-marking” concept (Haswell, 1983, which requires dramatically more student engagement, resulted in more successful learning outcomes for surface-level knowledge acquisition than the more traditional approach of “teacher-corrects-all.” Results suggest it would be effective, not just for grammar, punctuation, and word usage, the objective here, but for any material that requires rote-memory learning, such as the Associated Press or Canadian Press style rules used by news publications across North America.

    This paper provides some historical background on the commercial production of radioisotopes in Canada, and the evolution of the present vendor, MDS Nordion. The chief isotopes are molybdenum 99, iodine 131, and cobalt 60. Cobalt 60 for medical sterilization and irradiation is considered to be a significant growing market. Food irradiation is believed to be a big marketing opportunity, although attempts to popularize it have so far met with limited success. Candu reactors supply the bulk of the world's 60 Co supply. Eighty percent of the world's 99 Mo supply for medical imaging comes from Canada, and is at present produced in NRU Reactor, which is to be replaced by two Maple reactors coming into production in 1999 and 2000

The industrial partners, however, were not so sure about the effectiveness of this collaborative training endeavor because there were many skirmishes between company supervisors and Vietnamese interns caused by the interns’ self-interested perception and expectation. Consequently, a theoretical framework for predicting internship acceptance and preventing unfavorable perceptions was proposed to strengthen the proactive assessment methodology. Collaboration research, funding agencies, academia, and industry could all benefit from this study.

    Full Text Available Fecal samples play an important role in giant panda conservation studies. Optimal preservation conditions and choice of microsatellites for giant panda fecal samples have not been established. In this study, we evaluated the effect of four factors (namely, storage type (ethanol (EtOH, EtOH −20 °C, 2-step storage medium, DMSO/EDTA/Tris/salt buffer (DETs and frozen at −20 °C, storage time (one, three and six months, fragment length, and repeat motif of microsatellite loci on the success rate of microsatellite amplification, allelic dropout (ADO and false allele (FA rates from giant panda fecal samples. Amplification success and ADO rates differed between the storage types. Freezing was inferior to the other four storage methods based on the lowest average amplification success and the highest ADO rates (P < 0.05. The highest microsatellite amplification success was obtained from either EtOH or the 2-step storage medium at three storage time points. Storage time had a negative effect on the average amplification of microsatellites and samples stored in EtOH and the 2-step storage medium were more stable than the other three storage types. We only detected the effect of repeat motif on ADO and FA rates. The lower ADO and FA rates were obtained from tri- and tetra-nucleotide loci. We suggest that freezing should not be used for giant panda fecal preservation in microsatellite studies, and EtOH and the 2-step storage medium should be chosen on priority for long-term storage. We recommend candidate microsatellite loci with longer repeat motif to ensure greater genotyping success for giant panda fecal studies.

    Mounting evidence indicates that worldwide, innovation systems are increasing unsustainable. Equally, concerns about inequities in the science and innovation process, and in access to its benefits, continue. Against a backdrop of growing health, economic and scientific challenges global stakeholders are urgently seeking to spur innovation and maximize the just distribution of benefits for all. Open Science collaboration (OS) - comprising a variety of approaches to increase open, public, and rapid mobilization of scientific knowledge - is seen to be one of the most promising ways forward. Yet, many decision-makers hesitate to construct policy to support the adoption and implementation of OS without access to substantive, clear and reliable evidence. In October 2017, international thought-leaders gathered at an Open Science Leadership Forum in the Washington DC offices of the Bill and Melinda Gates Foundation to share their views on what successful Open Science looks like. Delegates from developed and developing nations, national governments, science agencies and funding bodies, philanthropy, researchers, patient organizations and the biotechnology, pharma and artificial intelligence (AI) industries discussed the outcomes that would rally them to invest in OS, as well as wider issues of policy and implementation. This first of two reports, summarizes delegates' views on what they believe OS will deliver in terms of research, innovation and social impact in the life sciences. Through open and collaborative process over the next months, we will translate these success outcomes into a toolkit of quantitative and qualitative indicators to assess when, where and how open science collaborations best advance research, innovation and social benefit. Ultimately, this work aims to develop and openly share tools to allow stakeholders to evaluate and re-invent their innovation ecosystems, to maximize value for the global public and patients, and address long-standing questions

  5. Evolution, Appearance, and Occupational Success

    Full Text Available Visual characteristics, including facial appearance, are thought to play an important role in a variety of judgments and decisions that have real occupational outcomes in many settings. Indeed, there is growing evidence suggesting that appearance influences hiring decisions and even election results. For example, attractive individuals are more likely to be hired, taller men earn more, and the facial appearance of candidates has been linked to real election outcomes. In this article, we review evidence linking physical appearance to occupational success and evaluate the hypothesis that appearance based biases are consistent with predictions based on evolutionary theories of coalition formation and leadership choice. We discuss why appearance based effects are so pervasive, addressing ideas about a “kernel of truth” in attributions and about coalitional psychology. We additionally highlight that appearance may be differently related to success at work according to the types of job or task involved. For example, leaders may be chosen because the characteristics they possess are seen as best suited to lead in particular situations. During a time of war, a dominant-appearing leader may inspire confidence and intimidate enemies while during peace-time, when negotiation and diplomacy are needed, interpersonal skills may outweigh the value of a dominant leader. In line with these ideas, masculine-faced leaders are favored in war-time scenarios while feminine-faced leaders are favored in peace-time scenarios. We suggest that such environment or task specific competencies may be prevalent during selection processes, whereby individuals whose appearance best matches perceived task competences are most likely selected, and propose the general term “task-congruent selection” to describe these effects. Overall, our review highlights how potentially adaptive biases could influence choices in the work place. With respect to certain biases

    2007-01-01

    Recent healthcare trends clearly show significant investment by healthcare institutions into various types of wired and wireless technologies to facilitate and support superior healthcare delivery. This trend has been spurred by the shift in the concept and growing importance of the role of health information and the influence of fields such as bio-informatics, biomedical and genetic engineering. The demand is currently for integrated healthcare information systems; however for such initiatives to be successful it is necessary to adopt a macro model and appropriate methodology with respect to wireless initiatives. The key contribution of this paper is the presentation of one such integrative model for mobile health (m-health) known as the Wi-INET Business Model, along with a detailed Adaptive Mapping to Realisation (AMR) methodology. The AMR methodology details how the Wi-INET Business Model can be implemented. Further validation on the concepts detailed in the Wi-INET Business Model and the AMR methodology is offered via a short vignette on a toolkit based on a leading UK-based healthcare information technology solution.

    Full Text Available Ageing of farmers in Nigeria and especially in capitalized sectors of agriculture requires attention to enhance sustainability and food security. The study thus examined the farm succession plans of 60 long established poultry farmers purposively selected from the Poultry Association of Nigeria in Ogun State Nigeria. Descriptive statistics and the Chi square analysis were used to present the findings of the study. Mean age of respondents was 61years. Their children were mostly over 18years (65%. Poultry farms were solely owned (76.7% with mean age of 17.9 years. Succession rate i.e. identification of a successor was eighty percent and were mostly respondents children (63.3%. This choice was based on their level of involvement in the business (63.6%. Majority (60% were not willing to fully retire from farming until death. Chi square analysis revealed age of farmer was significantly related to succession rate.

    2013-10-01

    The literature supporting nurse manager succession planning is reviewed and synthesised to discover best practice for identifying and developing future nurse managers. Healthcare succession planning practices are lacking. Nurse managers are historically selected based on clinical skills and lack formal leadership preparation. A systematic literature search appraises and summarises the current literature supporting nurse manager succession planning. Multiple reviewers were used to increase the reliability and validity of article selection and analysis. New nurse managers require months to adapt to their positions. Deliberate nurse manager succession planning should be integrated in the organisation's strategic plan and provide a proactive method for identifying and developing potential leaders. Organisations that identify and develop internal human capital can improve role transition, reduce nurse manager turnover rates and decrease replacement costs. Despite the clear benefits of succession planning, studies show that resource allocation for proactive, deliberate development of current and future nurse leaders is lacking. Additionally, systematic evaluation of succession planning is limited. Deliberate succession planning efforts and appropriate resource allocation require strategic planning and evaluation methods. Detailed evaluation methods demonstrating a positive return on investment utilising a cost-benefit analysis and empirical outcomes are necessary. © 2013 John Wiley & Sons Ltd.

    This report presents the results of a study of secondary plant succession on disturbed sites created during initial site investigations in the late 1970s and early 1980s at Yucca Mountain, NV. Specific study objectives were to determine the rate and success of secondary plant succession, identify plant species found in disturbances that may be suitable for site-specific reclamation, and to identify environmental variables that influence succession on disturbed sites. During 1991 and 1992, fifty seven disturbed sites were located. Vegetation parameters, disturbance characteristics and environmental variables were measured at each site. Disturbed site vegetation parameters were compared to that of undisturbed sites to determine the status of disturbed site plant succession. Vegetation on disturbed sites, after an average of ten years, was different from undisturbed areas. Ambrosia dumosa, Chrysothamnus teretifolius, Hymenoclea salsola, Gutierrezia sarothrae, Atriplex confertifolia, Atriplex canescens, and Stephanomeria pauciflora were the most dominant species across all disturbed sites. With the exception of A. dumosa, these species were generally minor components of the undisturbed vegetation. Elevation, soil compaction, soil potassium, and amounts of sand and gravel in the soil were found to be significant environmental variables influencing the species composition and abundance of perennial plants on disturbed sites. The recovery rate for disturbed site secondary succession was estimated. Using a linear function (which would represent optimal conditions), the recovery rate for perennial plant cover, regardless of which species comprised the cover, was estimated to be 20 years. However, when a logarithmic function (which would represent probable conditions) was used, the recovery rate was estimated to be 845 years. Recommendations for future studies and site-specific reclamation of disturbances are presented

  1. The Success of Podcasting as a Success for Science Outreach

    Haupt, R. J.; Wheatley, P.; Padilla, A. J.; Barnhart, C. J.

    2015-12-01

    Podcasts are downloadable web-hosted audio programs (radio on demand). The medium's popularity has grown immensely since its beginning 10+ years ago. "Science and Medicine" remains a prominent category in iTunes (the most popular podcast marketplace), but is unfortunately inundated with non-scientific and dubious content (e.g. the paranormal, health fads, etc.). It seems unlikely that legitimate science content would thrive in such an environment. However, our experience as an independent science podcast shows it is possible to successfully present authentic science to a general audience and maintain popularity. Our show, Science… sort of, began in the fall of 2009, and we have since produced episodes regularly. As of July 31, 2015, our feed hosts 235 episodes, with an average ~6,700 downloads per episode, and over 1.6 million total downloads originating from all across the globe. Thanks to listener involvement and contribution, the show is financially self-sustaining. While production requires a significant time input, no external financial support from the creators or other granting agencies is needed. Traditional media outlets rely on advertisers, thus pressuring shows to produce "popular" content featuring science celebrities. In contrast, independent podcasts can interview big name science communicators, such as Dr. Neil DeGrasse Tyson, while also exploring the research of graduate students and early career scientists. This level playing field provides an unprecedented opportunity for studies to reach a global audience and share research that previously may have only be seen by those at a specialized conference or subscribed to niche journals. Further, direct public engagement helps the audience personally connect to the research and researcher. In combination with other social media platforms, podcasting is a powerful tool in the outreach arsenal, enabling one to share science directly with the world in a way that both educates and excites listeners.

    Money motivates mitigation. An example of success in communicating scientific information about hazards, coupled with information about available money, is the follow-up action by local governments to actually mitigate. The Nevada Hazard Mitigation Planning Committee helps local governments prepare competitive proposals for federal funds to reduce risks from natural hazards. Composed of volunteers with expertise in emergency management, building standards, and earthquake, flood, and wildfire hazards, the committee advises the Nevada Division of Emergency Management on (1) the content of the State’s hazard mitigation plan and (2) projects that have been proposed by local governments and state agencies for funding from various post- and pre-disaster hazard mitigation programs of the Federal Emergency Management Agency. Local governments must have FEMA-approved hazard mitigation plans in place before they can receive this funding. The committee has been meeting quarterly with elected and appointed county officials, at their offices, to encourage them to update their mitigation plans and apply for this funding. We have settled on a format that includes the county’s giving the committee an overview of its infrastructure, hazards, and preparedness. The committee explains the process for applying for mitigation grants and presents the latest information that we have about earthquake hazards, including locations of nearby active faults, historical seismicity, geodetic strain, loss-estimation modeling, scenarios, and documents about what to do before, during, and after an earthquake. Much of the county-specific information is available on the web. The presentations have been well received, in part because the committee makes the effort to go to their communities, and in part because the committee is helping them attract federal funds for local mitigation of not only earthquake hazards but also floods (including canal breaches) and wildfires, the other major concerns in

    Sphagnum mosses are widespread in areas where mires exist and constitute a globally important carbon sink. Their ecophysiology is known to be related to the water level, but very little is currently known about the successional trend in Sphagnum. We hypothesized that moss species follow the known vascular plant growth strategy along the successional gradient (i.e., decrease in production and maximal photosynthesis while succession proceeds). To address this hypothesis, we studied links between the growth and related ecophysiological processes of Sphagnum mosses from a time-since-initiation chronosequence of five wetlands. We quantified the rates of increase in biomass and length of different Sphagnum species in relation to their CO(2) assimilation rates, their photosynthetic light reaction efficiencies, and their physiological states, as measured by the chlorophyll fluorescence method. In agreement with our hypothesis, increase in biomass and CO(2) exchange rate of Sphagnum mosses decreased along the successional gradient, following the tactics of more intensely studied vascular plants. Mosses at the young and old ends of the chronosequence showed indications of downregulation, measured as a low ratio between variable and maximum fluorescence (F(v)/F(m)). Our study divided the species into three groups; pioneer species, hollow species, and ombrotrophic hummock formers. The pioneer species S. fimbriatum is a ruderal plant that occurred at the first sites along the chronosequence, which were characterized by low stress but high disturbance. Hollow species are competitive plants that occurred at sites with low stress and low disturbance (i.e., in the wet depressions in the middle and at the old end of the chronosequence). Ombrotrophic hummock species are stress-tolerant plants that occurred at sites with high stress and low disturbance (i.e., at the old end of the chronosequence). The three groups along the mire successional gradient appeared to be somewhat analogous

    We document a tendency for published estimates of population size in sea turtles to be increasing rather than decreasing across the globe. To examine the population status of the seven species of sea turtle globally, we obtained 299 time series of annual nesting abundance with a total of 4417 annual estimates. The time series ranged in length from 6 to 47 years (mean, 16.2 years). When levels of abundance were summed within regional management units (RMUs) for each species, there were upward trends in 12 RMUs versus downward trends in 5 RMUs. This prevalence of more upward than downward trends was also evident in the individual time series, where we found 95 significant increases in abundance and 35 significant decreases. Adding to this encouraging news for sea turtle conservation, we show that even small sea turtle populations have the capacity to recover, that is, Allee effects appear unimportant. Positive trends in abundance are likely linked to the effective protection of eggs and nesting females, as well as reduced bycatch. However, conservation concerns remain, such as the decline in leatherback turtles in the Eastern and Western Pacific. Furthermore, we also show that, often, time series are too short to identify trends in abundance. Our findings highlight the importance of continued conservation and monitoring efforts that underpin this global conservation success story.

    2012-01-01

    Advancements in the robotic surgical technology have revolutionized the standard of care for many surgical procedures. The purpose of this review is to evaluate the important considerations in developing a new robotics program at a given healthcare institution. Patients' interest in robotic-assisted surgery has and continues to grow because of improved outcomes and decreased periods of hospitalization. Resulting market forces have created a solid foundation for the implementation of robotic surgery into surgical practice. Given proper surgeon experience and an efficient system, robotic-assisted procedures have been cost comparable to open surgical alternatives. Surgeon training and experience is closely linked to the efficiency of a new robotics program. Formally trained robotic surgeons have better patient outcomes and shorter operative times. Training in robotics has shown no negative impact on patient outcomes or mentor learning curves. Individual economic factors of local healthcare settings must be evaluated when planning for a new robotics program. The high cost of the robotic surgical platform is best offset with a large surgical volume. A mature, experienced surgeon is integral to the success of a new robotics program.

    Full Text Available Background: The Faculty of Medical Sciences, University of Zahedan implemented the Objective Structured Clinical Examination (OSCE in the final Examination during the 2003–2004 academic year. Simultaneously, the pediatric department initiated faculty and student training, and instituted the OSCE as an assessment instrument during the pediatric clerkship in year 5. The study set out to explore student acceptance of the OSCE as part of an evaluation of the Pediatric clerkship.Purpose: This study implemented to evaluate a new method of assessment in medical education in pediatrics.Methods: A self-administered questionnaire was completed by successive groups of students immediately after the OSCE at the end of each clerkship rotation. Main outcome measures were student perception of examination attributes, which included the quality of instructions and organization, the quality of performance, authenticity and transparency of the process, and usefulness of the OSCE as an assessment instrument compared to other methods.Results: There was overwhelming acceptance of the OSCE in Pediatric with respect to the comprehensiveness (90%, transparency (87%, fairness (57% and authenticity of the required tasks (58–78%. However, students felt that it was a strong anxiety-producing experience. And concerns were expressed regarding the ambiguity of some questions and inadequacy of time for expected tasks.Conclusion: Student feedback was invaluable in influencing faculty teaching, curriculum direction and appreciation of student opinion. Further psychometric evaluation will strengthen the development of the OSCE.Key words: OSCE, COMPETENCE ASSESSMENT

    The author began this presentation by giving a corporate profile of PanCanadian, discussing its evolution over time to it being spun-off of PanCanadian Petroleum Limited from Canadian Pacific to form PanCanadian Energy Corporation in 2001. The worldwide activities were mentioned. PanCanadian Petroleum Limited is one of the country's largest producers, experiencing emerging international exploration success, and marketing energy throughout North America. It is also a company that is financially strong. PanCanadian is involved in natural gas, crude, natural gas liquids, and power. An outline of PanCanadian Energy Services was provided, along with its strategic positioning. The next section of the presentation focused on Nova Scotia natural gas, beginning with a map displaying the Eastern Canada development. The focus shifted to the Deep Panuke field, where exploration began in early 1999. PanCanadian holds 20 per cent of the Scotian Shelf. The industry activity offshore Nova Scotia began with the first well in 1967, and to date 178 wells have been drilled, of which 106 were exploration wells. There have been 21 significant discoveries. Production in the Deep Panuke is expected to begin during the first quarter of 2005. The various approval agencies were listed. With large interests held in the offshore Nova Scotia and extensive exploration plans, PanCanadian opportunity in Eastern Canada, New England and the Mid-Atlantic markets has greatly increased. refs., tabs., figs

  8. The success story of crystallography.

    Schwarzenbach, Dieter

    2012-01-01

    Diffractionists usually place the birth of crystallography in 1912 with the first X-ray diffraction experiment of Friedrich, Knipping and Laue. This discovery propelled the mathematical branch of mineralogy to global importance and enabled crystal structure determination. Knowledge of the geometrical structure of matter at atomic resolution had revolutionary consequences for all branches of the natural sciences: physics, chemistry, biology, earth sciences and material science. It is scarcely possible for a single person in a single article to trace and appropriately value all of these developments. This article presents the limited, subjective view of its author and a limited selection of references. The bulk of the article covers the history of X-ray structure determination from the NaCl structure to aperiodic structures and macromolecular structures. The theoretical foundations were available by 1920. The subsequent success of crystallography was then due to the development of diffraction equipment, the theory of the solution of the phase problem, symmetry theory and computers. The many structures becoming known called for the development of crystal chemistry and of data banks. Diffuse scattering from disordered structures without and with partial long-range order allows determination of short-range order. Neutron and electron scattering and diffraction are also mentioned.

    For adult patients on prolonged mechanical ventilation (PMV, >/=21 days), successful weaning has been attributed to various factors. The purpose of this study was to describe patient outcomes, weaning rates and factors in successful weaning at a hospital-based respiratory care center (RCC) in Taiwan. This was a retrospective observational study performed in a 24-bed RCC over six years. A total of 1307 patients on PMV were included in the study. The overall survival rate was 62%. Fifty-six percent of patients were successfully weaned. Unsuccessfully weaned patients had higher MICU transfer rates, higher Acute Physiology and Chronic Health Evaluation II scores, longer duration of RCC stay, higher rates of being bed-ridden prior to admission, increased hemodialysis rates, higher modified Glasgow Coma Scale scores, higher rapid shallow breathing index, lower inspiratory pressure at residual volume (PImax) and lower blood urea nitrogen (BUN) and creatinine levels. Factors found to be associated with unsuccessful weaning were length of RCC stay (OR=1.04, Pventilator independence can be achieved in an RCC setting as an alternative to ICU care. Factors associated with unsuccessful weaning included longer duration of RCC stay, elevated BUN levels and lower modified GCS scores, serum albumin and PImax levels.

    The current nursing leadership pipeline is inadequate and demands strategic succession planning methods. This article provides concept clarification regarding nurse manager succession planning. Attributes common to succession planning include organizational commitment and resource allocation, proactive and visionary leadership approach, and a mentoring and coaching environment. Strategic planning, current and future leadership analysis, high-potential identification, and leadership development are succession planning antecedents. Consequences of succession planning are improved leadership and organizational culture continuity, and increased leadership bench strength. Health care has failed to strategically plan for future leadership. Developing a strong nursing leadership pipeline requires deliberate and strategic succession planning. © 2013 Wiley Periodicals, Inc.

    Geoffrey Miller has hypothesized that producing artwork functions as a mating display. Here we investigate the relationship between mating success and artistic success in a sample of 236 visual artists. Initially, we derived a measure of artistic success that covered a broad range of artistic behaviors and beliefs. As predicted by Miller’s evolutionary theory, more successful male artists had more sexual partners than less successful artists but this did not hold for female artists. Also, male artists with greater artistic success had a mating strategy based on longer term relationships. Overall the results provide partial support for the sexual selection hypothesis for the function of visual art. PMID:22059085

    Becoming a successful manager in a health care agency is, for most new managers, an awesome goal. Successful management is more than knowledge of leadership roles and management functions that can be learned in school or educational workshops. Successful management involves effective use of both the manager's affective and cognitive domains. Mentoring and apprenticeship with a successful nurse leader is for many novice managers a highly valuable way to learn management skills since this allows for techniques with a successful nurse manager to be visualized and then modeled. "Seven S's" that provide a framework for managerial success are discussed.

    Science education has been involved in a crisis due to the way in which teachers teach future teachers (McDermott, 1990; Bernal, 2005). During generations, students have been learning sciences as something already done, based on memorizing a number of contents or formulas that always give a correct answer (CUSE, 1997). Thus, Lederman y Abd-El-Khalick (1998) considered that is difficult that future teachers feel Science as something tempting and based on empiricism, if they only learn contents. To learn Science it is required to think, to do and to talk (Pujol, 2003). In this study an experience where students are teachers is shown. 160 students from the Faculty of Education have participated. They had to make, in cooperative groups of four, several activities to eliminate typical Science conceptual mistakes in children (such as minerals and rocks as the same thing, or the proportion of the Earth flattened out at the poles). Some peer groups have to develop activities as kids, question teachers and extract activity strengths and weakness from a kid point of view. A condition of these activities is that they are not mere teacher's demonstrations. Kids have to discover by themselves the conceptual mistake throughout the proposed activity. Afterwards, teacher's groups pass to occupy children's role and vice-versa with new activities from other conceptual mistakes. The experience was tested from two different points of view: a) student's perception of the experience, and b) final exam outcomes. Results show that 95% of the students prefer to be explained by their peers than by the lecturer. As outcomes, 94% of the students that experienced with their peers these activities and explanations, answer successfully the exam questions, while in former experiences where lecturer explain the same concepts, this value decreased up to 64%. These results coincide with other experiences concluding that students have more success than the teacher to make understand concepts to their

    Efforts to introduce hospice and palliative care into American prisons have become fairly widespread, in response to the sharp increase in inmate deaths. The primary impetus originally came from the alarming number of AIDS deaths among prisoners. The new combination therapies have proved very successful in treating AIDS, but are very costly, and many problems must be overcome to ensure their effectiveness in correctional settings. Although the AIDS epidemic seems to be in decline, prisons are experiencing a rise in the number of deaths due to "natural causes." In this article we present a review of the prison hospice scene--the response to this crisis in correctional health care. First, we discuss the challenges facing the introduction of hospice into the correctional setting. Then, we present a brief overview of recent developments and a discussion of some ways hospice components have been adapted for life behind bars. Finally, we indicate some of the prospects for the future. Hospice professionals, armed with thorough professional training and years of experience, often fear that correctional health care providers will only parody superficial aspects of the hospice approach. Continual nudging and nurturing by local and state hospice professionals is required in order to bring about this change in the first place and to sustain it through time. Prison hospice workers need not only initial training, but also ongoing education and personal contact with experienced hospice professionals. While the interest of the big national organizations is necessary, the real action happens when local hospices work with nearby prisons to attend to the needs of dying inmates.

    To evaluate the delivery route and the indications for cesarean delivery after successful external cephalic version (ECV). A retrospective matched case-control study was conducted at a hospital in Lisbon, Portugal, between 2002 and 2012. Each woman who underwent successful ECV (n = 44) was compared with the previous and next women who presented for labor management and who had the same parity and a singleton vertex pregnancy at term (n = 88). The outcome measures were route of delivery, indications for cesarean delivery, and incidence of nonreassuring fetal status. Attempts at ECV were successful in 62 (46%) of 134 women, and 44 women whose fetuses remained in a cephalic presentation until delivery were included in the study. The rates of intrapartum cesarean delivery and operative vaginal delivery did not differ significantly between cases and controls (intrapartum cesarean delivery, 9 [20%] vs 16 [18%], P = 0.75; operative vaginal delivery, 14 [32%] vs 19 [22%], P = 0.20). The indications for cesarean delivery after successful ECV did not differ; in both groups, cesarean delivery was mainly performed for labor arrest disorders (cases, 6 [67%] vs controls, 13 [81%]; P = 0.63). Successful ECV was not associated with increased rates of intrapartum cesarean delivery or operative vaginal delivery. Copyright © 2014 International Federation of Gynecology and Obstetrics.

    Long distance atomic teleportation (LDAT) is of prime importance in long distance quantum communication. Scheme proposed by Bose et al. (1999) in principle enables us to have LDAT using cavity decay. However it gives message state dependent fidelity and success rate. Here, using interaction of entangled coherent states with atom–cavity systems and a two-step measurement, we show how, LDAT can be achieved with unit fidelity and as good success as desired under ideal conditions. The scheme is unique in that, the first measurement predicts success or failure. If success is predicted then second measurement gives perfect teleportation. If failure is predicted the message-qubit remains conserved therefore a second attempt may be started. We found that even in presence of decoherence due to dissipation of energy our scheme gives message state independent success rate and almost perfect teleportation in single attempt with mean fidelity of teleportation equal to 0.9 at long distances. However if first attempt fails, unlike ideal case where message-qubit remains conserved with unit fidelity, in presence of decoherence the message-qubit remains conserved to some degree, therefore mean fidelity of teleportation can be increased beyond 0.9 by repeating the process.

    As the nation's central bank, the Bank of England is committed to promoting and maintaining monetary and financial stability. Broadly speaking, this means that it sets the interest rate at a level such that the economy should meet the UK government's 2% inflation target in the medium term, and it analyses the financial system to identify and reduce systemic risks to the country's financial infrastructure. The Bank also performs several other critical functions, including managing the approximately £42bn worth of banknotes in circulation and managing the nation's foreign-currency reserves - a multicurrency fund worth some £23bn. As a physicist, I find that I can make a full contribution to this work.

  19. REAL INTEREST RATES AND GOVERNMENT DEBT DURING STABILIZATION

    OpenAIRE

    1989-01-01

    High real interest rates typically accompany successful disinflations. If government deficits are financed with domestic debt, this behavior of interest rates can be destabilizing. High interest rates increase debt service costs and contribute to the accumulation of debt, threatening the whole anti-inflation effort. The exchange rate regime matters in this context. Under perfectly flexible exchange rates, the real interest rate is invariant to changes in the rate of money creation. By contras...

    There is currently a lack of consensus on the definition of successful aging (SA) and existing implementations have omitted constructs associated with SA. We used empirical methods to develop a dimensional model of SA that incorporates a wider range of associated variables, and we examined the relationship among these components using factor analysis and Bayesian Belief Nets. We administered a successful aging questionnaire comprising several standardized measures related to SA to a sample of 1948 older women enrolled in the San Diego site of the Women's Health Initiative study. The SA-related variables we included in the model were self-rated successful aging, depression severity, physical and emotional functioning, optimism, resilience, attitude towards own aging, self-efficacy, and cognitive ability. After adjusting for age, education and income, we fitted an exploratory factor analysis model to the SA-related variables and then, in order to address relationships among these factors, we computed a Bayesian Belief Net (BBN) using rotated factor scores. The SA-related variables loaded onto five factors. Based on the loading, we labeled the factors as follows: self-rated successful aging, cognition, psychosocial protective factors, physical functioning, and emotional functioning. In the BBN, self-rated successful aging emerged as the primary downstream factor and exhibited significant partial correlations with psychosocial protective factors, physical/general status and mental/emotional status but not with cognitive ability. Our study represents a step forward in developing a dimensional model of SA. Our findings also point to a potential role for psychiatry in improving successful aging by managing depressive symptoms and developing psychosocial interventions to improve self-efficacy, resilience, and optimism.
