Full Text Available Abstract Background There is strong, internationally confirmed evidence for the short-term effectiveness of multimodal interdisciplinary specific treatment programs for chronic back pain. However, the verification of long-term sustainability of achieved effects is missing so far. For long-term improvement of pain and functional ability high intervention intensity or high volume seems to be necessary (> 100 therapy hours. Especially in chronic back pain rehabilitation, purposefully refined aftercare treatments offer the possibility to intensify positive effects or to increase their sustainability. However, quality assured goal-conscious specific aftercare programs for the rehabilitation of chronic back pain are absent. Methods/Design This study aims to examine the efficacy of a specially developed bio-psycho-social chronic back pain specific aftercare intervention (RÜCKGEWINN in comparison to the current usual aftercare (IRENA and a control group that is given an educational booklet addressing pain-conditioned functional ability and back pain episodes. Overall rehabilitation effects as well as predictors for compliance to the aftercare programs are analysed. Therefore, a multicenter prospective 3-armed randomised controlled trial is conducted. 456 participants will be consecutively enrolled in inpatient and outpatient rehabilitation and assigned to either one of the three study arms. Outcomes are measured before and after rehabilitation. Aftercare programs are assessed at ten month follow up after dismissal form rehabilitation. Discussion Special methodological and logistic challenges are to be mastered in this trial, which accrue from the interconnection of aftercare interventions to their residential district and the fact that the proportion of patients who take part in aftercare programs is low. The usability of the aftercare program is based on the transference into the routine care and is also reinforced by developed manuals with structured

Full Text Available Treatment of chemical addiction includes preparation for treatment, formal treatment and aftercare. The latter appears to be a neglected area in service delivery to chemically addicted adolescents, contributing to the high relapse potential following treatment. The current qualitative study aimed at both exploring and describing the aftercare needs of chemically addicted adolescents. The chemically addicted adolescents included in this study received in-patient treatment as well as aftercare, but nonetheless experienced a relapse; necessitating further in-patient treatment. Purposive sampling was implemented to recruit 31 participants between the ages of 14 and 20 years. The sample size was determined by data saturation. Data for this exploratory, descriptive and contextual study were collected by means of narrative inquiry. Tesch’s framework for qualitative data analysis was employed and data verification was conducted through Guba’s model. The findings illustrated a need to attend to adolescents intrapersonal and interpersonal as well as environmental needs following treatment. The results can provide service providers with focus areas to be included in aftercare services to these adolescents.

2015-12-01

Without aftercare treatment, the period following discharge from short-term inpatient detoxification for opioid dependence presents a high risk of relapse. Yet the role of patient preference in treatment selection is rarely discussed in the substance-abuse literature. We surveyed 485 persons initiating inpatient opioid detoxification who were predominantly male (71.3%) and had detoxed in the past (73.2%). When asked to choose the one treatment that would work best for them after discharge, 43% of participants selected medication-assisted treatment (MAT), 29% preferred residential, 12% selected drug-free counseling, 12% NA/AA meetings only, and 4% preferred no additional treatment. Residential treatment preference was significantly associated with homelessness, having been in a detox program within the past year, and having pending legal problems, indicating that there is a distinct profile of detox patients who prefer residential treatment despite its limited availability. Detox program staff should work with patients to understand reasons for treatment preferences to optimize aftercare services. Copyright © 2015 Elsevier Inc. All rights reserved.

This study presents an improved gas module for the methodology. While the original version of the module focused narrowly on regulatory requirements for control of methane migration, the improved gas module also considers best available control technology for landfill gas in terms of greenhouse gas emissions, air quality, and emissions of odoriferous compounds. The improved module emphasizes the reduction or elimination of fugitive methane by considering the methane oxidation capacity of the cover system. The module also allows for the installation of biologically active covers or other features designed to enhance methane oxidation.

In most Western countries burn centres have been developed to provide acute and critical care for patients with severe burn injuries. Nowadays, those patients have a realistic chance of survival. However severe burn injuries do have a devastating effect on all aspects of a person's life. Therefore a well-organized and specialized aftercare system is needed to enable burn patients to live with a major bodily change. The aim of this study is to identify the problems and unmet care needs of patients with severe burn injuries throughout the aftercare process, both from patient and health care professional perspectives in Belgium. By means of face-to-face interviews (n = 40) with individual patients, responsible physicians and patient organizations, current experiences with the aftercare process were explored. Additionally, allied healthcare professionals (n = 17) were interviewed in focus groups. Belgian burn patients indicate they would benefit from a more integrated aftercare process. Quality of care is often not structurally embedded, but depends on the good intentions of local health professionals. Most burn centres do not have a written discharge protocol including an individual patient-centred care plan, accessible to all caregivers involved. Patients reported discontinuity of care: nurses working at general wards or rehabilitation units are not specifically trained for burn injuries, which sometimes leads to mistakes or contradictory information transmission. Also professionals providing home care are often not trained for the care of burn injuries. Some have to be instructed by the patient, others go to the burn centre to learn the right skills. Finally, patients themselves underestimate the chronic character of burn injuries, especially at the beginning of the care process. The variability in aftercare processes and structures, as well as the failure to implement locally developed best-practices on a wider scale emphasize the need for a comprehensive network

Placement of acid spoil materials

Pionke, H B; Rogowski, A S

1982-06-01

Potentially there are several chemical and hydrologic problems associated with placement of acid spoil materials. The rationale for a deep placement well below the soil surface, and preferably below a water table, is to prevent or minimize oxidation of pyrite to sulfuric acid and associated salts by reducing the supply of oxygen. If, however, substantial sulfuric acid or associated salts are already contained within the spoil because of present or previous mining, handling and reclamation operations (or if large supplies of indigenous salts exist, placement below a water table) may actually increase the rate of acid and salt leaching. Specific placement of acid- and salt-containing spoil should be aimed at preventing contact with percolating water or rising water tables. We recommend placement based on chemical and physical spoil properties that may affect water percolation O/sub 2/ diffusion rates in the profile. Both the deeper placement of acid spoil and coarser particle size can substantially reduce the amount of acid drainage. Placement above the water table with emphasis on percolate control may be better for high sulfate spoils, while placement below the non-fluctuating water table may be better for pyritic spoils.

[Effectiveness of aftercare treatment after release from prison: A first evaluation of the forensic therapeutic outpatient clinic for serious violent and sexual offenders in Berlin].

The Forensic Therapeutic Outpatient Clinic (FTA) in Berlin targets the professional aftercare treatment of classified high-risk violent and sexual offenders released from prison or forensic psychiatric hospitals. A comparison sample (n = 32) matched to the patients of the FTA (complete survey n = 32) according to similar criminal histories and diagnoses (ICD-10) was collected from offenders released from prison and forensic psychiatry at a time before the FTA was established. The focus of the study was on recidivism measured by complaints received by police departments during the follow-up period. Sexual recidivism occurred significantly later in the case of released offenders with aftercare treatment compared to those without. Moreover, for the duration of aftercare treatment the general risk of recidivism was approximately 85 % lower; however, after termination of treatment the recidivism rates of both samples converged to almost the same level. Individually adapted measures should be maintained after finishing aftercare treatment; however, because prisoners released from prison are frequently less prepared than patients from forensic psychiatric hospitals, the therapeutic work often reaches its limits in these cases. Therefore, social work should be taken into account right from the start.

There is an increasing interest in the humanitarian engineering curriculum, and a service-learning placement could be an important component of such a curriculum. International placements offer some important pedagogical advantages, but also have some practical and ethical limitations. Local community-based placements have the potential to be transformative for both the student and the community, although this potential is not always seen. In order to investigate the role of local placements, qualitative research interviews were conducted. Thirty-two semi-structured research interviews were conducted and analysed, resulting in a distinct outcome space. It is concluded that local humanitarian engineering placements greatly complement international placements and are strongly recommended if international placements are conducted. More importantly it is seen that we are better suited to address the marginalised in our own community, although it is often easier to see the needs of an outside populace.

Internet and mobile phones open new avenues for the optimization of health services in medical rehabilitation. Various models of Internet-delivered aftercare after psychosomatic inpatient treatment have shown promising results. The focus of this report is on the experience in translating one of the promising models, the Internet-Bridge ("Internet-Brücke"), to every day health care. Effectiveness was estimated through comparison of 254 patients who were treated in a hospital specialized in psychosomatic medicine and who participated in the Internet-Bridge as well as in the 1-year follow-up in the frame of standard quality assurance between 2003-2010 with 364 patients of the same hospital who also participated in the 1-year follow-up, but did not utilize the aftercare. Sustainable, reliable, and clinically significant improvements were more frequent in participants of the Internet-Bridge, especially with regard to psychological well-being, social problems, and psychosocial competence-at small additional costs. Results are understood as encouragement to start translation to routine care accompanied by research.

Incarcerated women with co-occurring mental health and substance use disorders (COD) face complex psychosocial challenges at community reentry. This study used qualitative methods to evaluate the perspectives of 14 prison and aftercare providers about service delivery challenges and treatment needs of reentering women with COD. Providers viewed the needs of women prisoners with COD as distinct from those of women with substance use alone and from men with COD. Providers described optimal aftercare for women with COD as including contact with the same provider before and after release, access to services within 24-72 hours after release, assistance with managing multiple social service agencies, assistance with relationship issues, and long-term follow-up. Providers also described larger service system and societal issues, including systems integration and ways in which a lack of prison and community aftercare resources impacted quality of care and reentry outcomes. Practice and policy implications are provided.

The respective rates of obesity in Canada and the United states are estimated to be 24.1% and 34.1%. Due to the increased incidence of obesity, Bariatric surgery has been recognized as one of the treatment options. Patients who have undergone Bariatric surgery tend to need chronic long-term follow-up with a multi-disciplinary team. In the past decade, there has been massive advancement and development in Internet, Web-based and Smartphone technologies. However, there seemed to be a pacuity of applications in this area that enables post-bariatric patients to self-manage their own condition. In addition, past research have highlighted the limited evidence based with regards to currently available bariatric applications, mainly due to the lack of medical professionals involvement. Our current research objective is to illustrate the development of a Bariatric After-care smartphone application and to highlight user preferences with regards to the features integrated within the application. The Bariatric Aftercare application was developed between the months of March 2014 to April 2014. Making use of low-cost online web-based application developmental technologies, the authors embarked on the development of the web-based application. Patients who attended their routine follow-up appointments are given the links to the web-based application. They were also recruited to participate in an online user evaluation survey to identify their preferences with regards to the features integrated. Since the inception of the web-based application to date, there has been a cumulative total of 385 unique assess to the online web-based application. There is a slight change in the confidence levels of the participants with regards to using the application to help them self-manage their own condition. The majority of the users have indicated that they preferred the information pertaining to what happens during each consult with members of the multidisciplinary team and also greatly valued

Weight bearing after lower extremity fractures still remains a highly controversial issue. Even in ankle fractures, the most common lower extremity injury no standard aftercare protocol has been established. Average non weight bearing times range from 0 to 7 weeks, with standardised, radiological healing controls at fixed time intervals. Recent literature calls for patient-adapted aftercare protocols based on individual fracture and load scenarios. We show the clinical feasibility and first results of a new, insole embedded gait analysis tool for continuous monitoring of gait, load and activity. Ten patients were monitored with a new, independent gait analysis insole for up to 3 months postoperatively. Strict 20 kg partial weight bearing was ordered for 6 weeks. Overall activity, load spectrum, ground reaction forces, clinical scoring and general health data were recorded and correlated. Statistical analysis with power analysis, t-test and Spearman correlation was performed. Only one patient completely adhered to the set weight bearing limit. Average time in minutes over the limit was 374 min. Based on the parameters load, activity, gait time over 20 kg weight bearing and maximum ground reaction force high and low performers were defined after 3 weeks. Significant difference in time to painless full weight bearing between high and low performers was shown. Correlation analysis revealed a significant correlation between weight bearing and clinical scoring as well as pain (American Orthopaedic Foot and Ankle Society (AOFAS) Score rs=0.74; Olerud-Molander Score rs=0.93; VAS pain rs=-0.95). Early, continuous gait analysis is able to define aftercare performers with significant differences in time to full painless weight bearing where clinical or radiographic controls could not. Patient compliance to standardised weight bearing limits and protocols is low. Highly individual rehabilitation patterns were seen in all patients. Aftercare protocols should be adjusted to real

Rehabilitation after lower-extremity fractures is based on the physicians' recommendation for non-, partial-, or full weight-bearing. Clinical studies rely on this assumption, but continuous compliance or objective loading rates are unknown. The purpose of this study was to determine the compliance to weight-bearing recommendations by introducing a novel, pedobarography system continuously registering postoperative ground forces into ankle, tibial shaft and proximal femur fracture aftercare and test its feasibility for this purpose. In this prospective, observational study, a continuously measuring pedobarography insole was placed in the patients shoe during the immediate post-operative aftercare after ankle, tibial shaft and intertrochanteric femur fractures. Weight-bearing was ordered as per the institutional standard and controlled by physical therapy. The insole was retrieved after a maximum of six weeks (28 days [range 5-42 days]). Non-compliance was defined as a failure to maintain, or reach the ordered weight-bearing within 30%. Overall 30 patients were included in the study. Fourteen (47%) of the patients were compliant to the weight-bearing recommendations. Within two weeks after surgery patients deviated from the recommendation by over 50%. Sex, age and weight did not influence the performance (p > 0.05). Ankle fracture patients (partial weight-bearing) showed a significantly increased deviation from the recommendation (p = 0.01). Our study results show that, despite physical therapy training, weight-bearing compliance to recommended limits was low. Adherence to the partial weight-bearing task was further decreased over time. Uncontrolled weight-bearing recommendations should thus be viewed with caution and carefully considered as fiction. The presented insole is feasible to determine weight bearing continuously, could immediately help define real-time patient behaviour and establish realistic, individual weight-bearing recommendations.

An aftercare programme following medical rehabilitation may be beneficial in order to reinforce and stabilize the positive effects of rehabilitation and to encourage individual health-related modifications of behaviour and lifestyle. Medical rehabilitation and the aftercare programme of the German Pension Insurance Fund primarily are intended to sustain earning capacity. As part of an evaluation of the Intensified Rehabilitation Aftercare Programme (IRENA) established by the German Pension Insurance Fund, work-related aspects in orthopaedic patients were analyzed based on various data sources. Firstly, the significance of institutional and individual conditions for utilization of IRENA alongside work was of interest. Secondly, the IRENA participants' judgements of the changes of work-related parameters due to the programme were examined, differentiating specifically by extent of earning capacity impairments as well as by particular work problems. The data set used for the analysis is composed of person-related routine data of the German Pension Insurance Fund relative to IRENA records of the year 2007 (n=30 663), interview data from orthopaedic rehabilitation centres providing IRENA (n=225), and questionnaires of IRENA participants (n=750) that were either collected during a broad evaluation of the IRENA programme or provided by the German Pension Insurance Fund. The results show that the compatibility of IRENA and work is facilitated by the institutional conditions. However, differences between inpatient and outpatient settings have to be recognized. The possibilities to participate in IRENA throughout the day frequently are more diverse in an outpatient setting. In contrast to inpatient centres, outpatient rehabilitation centres see clearly better chances for patients to return to work and to participate in IRENA alongside. With respect to the work-related parameters (work ability, periods of sick leave), clear improvements were reported by participants from

A critical evaluation of student radiographers' experience of the transition from the classroom to their first clinical placement

International Nuclear Information System (INIS)

2015-01-01

Introduction: Students studying for qualifications which enable them to apply for registration as health care professionals are expected to undertake a large amount of clinical placement to support their learning. The BSc Hons Diagnostic Radiography at one post-1992 UK University is no exception. It was identified in a previous study by this researcher that a relatively large number of first year student radiographers were unsure, or nervous, about some aspects of the transition to their first clinical placement. It was felt that further investigation into the student experience of the transition to the first clinical placement was warranted. Methodology: A mixed-methods survey approach was used to elicit quantitative and qualitative data from current radiography students, academic staff and clinical staff about student experience of the transition to the first clinical placement. Results: In general, most students enjoyed their first clinical placement, and the opportunity to put theory into practice. However, three key themes emerged from the data that caused students difficulty in the first clinical placement; working with clinical staff, working with very ill patients, and moving around the department each week. Key Conclusions: This study has identified that some aspects of the transition into the first clinical placement need to be improved. Recommendations have been made for curriculum development in the academic block prior to the first clinical placement, and to improve student support during clinical placement. The implementation of these recommendations is crucial to reduce the dissonance between theory and practice, and improve student experience of the transition to the first clinical placement. - Highlights: • Issues for student radiographers during their first clinical placement are identified. • Recommendations made for curriculum development to improve preparation for clinical placement. • Recommendations made to improve student support in

Immediate Placement of Ultrawide-Diameter Implants in Molar Sockets: Description of a Recommended Technique.

Science.gov (United States)

Hattingh, André C; De Bruyn, Hugo; Ackermann, Andrew; Vandeweghe, Stefan

Immediate implant placement is performed less frequently in molar extraction sockets than in single root sockets. This is mainly due to the tripodal anatomical configuration of molar roots, which is perceived as complex and therefore unsuitable. The mechanical burden of molar sites, combined with much larger socket dimensions, make it amenable to the use of ultrawide-diameter dental implants. This article describes a practical, sequenced technique that can be used predictably for immediate implant placement in maxillary and mandibular first molar sockets, using a dry skull model for clarification. This detailed description is based on the experience of more than 580 clinical cases over a 10-year period.

Full Text Available Traditional recommendations suggest placement of a subclavian central venous catheter (CVC ipsilateral to a known pneumothorax to minimize risk of bilateral pneumothorax. We present the case of a 65-year-old male with a right hemopneumothorax who was found to have intrathoracic placement of his right subclavian CVC at thoracotomy despite successful aspiration of blood and transduction of central venous pressure (CVP. We thus recommend extreme caution with the interpretation of CVC placement by blood aspiration and CVP measurement alone in patients with large volume ipsilateral hemothorax.

Quality assurance plan for placement of cold-cap grout, demonstration vault, Hanford Grout Vault Program. Final report

Energy Technology Data Exchange (ETDEWEB)

Harrington, P.T.; Wakeley, L.D.; Ernzen, J.J.; Walley, D.M.

1992-08-01

During FY 91, the U.S. Army Engineer Waterways Experiment Station (WES) developed a grout to be used as a cold cap, a nonradioactive layer, between the solidified waste and the cover blocks of a demonstration waste disposal vault at the U.S. Department of Energy Hanford Facility. This document recommends requirements for a quality assurance (QA) plan for field mixing and placing of the cold-cap grout during final closure of the demonstration vault. Preplacement activities emphasize selection and testing of materials that will match the performance of materials used in the WES grout. Materials sources and applicable American Society of Testing and Materials, American Concrete Institute, and American Petroleum Institute specifications and requirements are provided. Archiving of physical samples of materials is essential, in addition to careful maintenance of test reports and laboratory data. Full-scale field trial mixing and a detailed preconstruction conference are recommended. Placement activities focus on production and placement of a grout that remains sufficiently constant throughout all batches and meets performance requirements. QA activities must be coordinated between the batch plant and delivery site. Recommended sampling during placement includes cylinders cast for subsequent tests of compressive strength and for nondestructive evaluation and prisms cast for monitoring volume stability. A minimum of two lifts is recommended. Postplacement activities include long-term monitoring of the properties of grout specimens cast during placement. Minimum testing of cylinders includes pulse velocity, fundamental frequency, and unconfined compressive strength. Monitoring characteristics of the microstructure also are recommended. The QA plan should designate an organization to have responsibility for maintaining complete records, reports, and archived samples, including details of deviations from plans written before field placement.

Relapse rates in bulimia nervosa (BN) are high even after successful treatment, but patients often hesitate to take up further treatment. An easily accessible program might help maintain treatment gains. Encouraged by the effects of Web-based eating disorder prevention programs, we developed a manualized, Web-based aftercare program (IN@) for women with BN following inpatient treatment. The objective of this study was to determine the efficacy of the web-based guided, 9-month, cognitive-behavioral aftercare program IN@ for women with BN following inpatient treatment. We conducted a randomized controlled efficacy trial in 253 women with DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, fourth edition) BN and compared the results of IN@ with treatment as usual (TAU). Assessments were carried out at hospital admission (T0), hospital discharge/baseline (T1), postintervention (T2; 9 months after baseline), 9-month follow-up (T3; 18 months after baseline). The primary outcome, abstinence from binge eating and compensatory behaviors during the 2 months preceding T2, was analyzed by intention to treat, using logistic regression analyses. Frequencies of binge eating and vomiting episodes, and episodes of all compensatory behaviors were analyzed using mixed effects models. At T2, data from 167 women were available. There were no significant differences in abstinence rates between the TAU group (n=24, 18.9%) and the IN@ group (n=27, 21.4%; odds ratio, OR=1.29; P=.44). The frequency of vomiting episodes in the IN@ group was significantly (46%) lower than in the TAU group (P=.003). Moderator analyses revealed that both at T2 and T3, women of the intervention group who still reported binge eating and compensatory behaviors after inpatient treatment benefited from IN@, whereas women who were already abstinent after the inpatient treatment did not (P=.004; P=.002). Additional treatment utilization was high in both groups between baseline and follow-up. Overall, data

The objectives of this study are to estimate smoke alarm coverage and adherence with national guidelines in low- to mid-value owner-occupied residences, and to identify resident demographic, behavioral, and building characteristics and other fire and burn safety practices associated with smoke alarm utilization. Baseline visits were conducted with 779 households in King County, Washington, for a randomized trial of smoke alarm functionality. Presence, functionality, features, and location of pre-existing smoke alarms were ascertained by staff observation and testing. Household and building descriptors were collected using questionnaires. Households were classified by presence of smoke alarms, functional alarms, and functional and properly mounted alarms placed in hallways and on each floor but not in recommended avoidance locations. Smoke alarms were present in 89%, and functional units in 78%, of households. Only 6-38% met all assessed functionality and placement recommendations. Homes frequently lacked alarms in any bedrooms or on each floor. Building age, but not renovation status, was associated with all dimensions of smoke alarm coverage; post-1980 constructions were 1.7 times more likely to comply with placement recommendations than were pre-1941 homes (95% CI: 1.1-2.6). Respondent education and race/ethnicity, children wood stoves and fireplaces, number of smoke alarms, recency of smoke alarm testing, carbon monoxide monitors, and fire ladders displayed varying relationships with alarm presence, functionality, and placement. Strategies for maintaining smoke alarms in functional condition and improving compliance with placement recommendations are necessary to achieve universal coverage, and will benefit the majority of households.

To examine the impact of using American Academy of Sleep Medicine (AASM) recommended EEG derivations (F4/M1, C4/M1, O2/M1) vs. a single derivation (C4/M1) in polysomnography (PSG) on the measurement of sleep and cortical arousals, including inter- and intra-observer variability. Prospective, non-blinded, randomized comparison. Three Australian tertiary-care hospital clinical sleep laboratories. 30 PSGs from consecutive patients investigated for obstructive sleep apnea (OSA) during December 2007 and January 2008. N/A. To examine the impact of EEG derivations on PSG summary statistics, 3 scorers from different Australian clinical sleep laboratories each scored separate sets of 10 PSGs twice, once using 3 EEG derivations and once using 1 EEG derivation. To examine the impact on inter- and intra-scorer reliability, all 3 scorers scored a subset of 10 PSGs 4 times, twice using each method. All PSGs were de-identified and scored in random order according to the 2007 AASM Manual for the Scoring of Sleep and Associated Events. Using 3 referential EEG derivations during PSG, as recommended in the AASM manual, instead of a single central EEG derivation, as originally suggested by Rechtschaffen and Kales (1968), resulted in a mean ± SE decrease in N1 sleep of 9.6 ± 3.9 min (P = 0.018) and an increase in N3 sleep of 10.6 ± 2.8 min (P = 0.001). No significant differences were observed for any other sleep or arousal scoring summary statistics; nor were any differences observed in inter-scorer or intra-scorer reliability for scoring sleep or cortical arousals. This study provides information for those changing practice to comply with the 2007 AASM recommendations for EEG placement in PSG, for those using portable devices that are unable to comply with the recommendations due to limited channel options, and for the development of future standards for PSG scoring and recording. As the use of multiple EEG derivations only led to small changes in the distribution of derived sleep

Conclusion: Individuals who harmed themselves had a high rate of psychiatric morbidity and interpersonal problems. However, their adherence to psychiatric outpatient aftercare was low. Improved identification of the needs of patients with suicidal tendencies who did not attend outpatient services will have implications for future services provided to this patient population, and will better enable medical personnel to most effectively assist in suicide attempt interventions.

The discharge process from hospital to home for patients with severe mental illness (SMI) is often complex, and most are in need of tailored and coordinated community services at home. One solution is to discharge patients to inpatient short-stay community residential aftercare (CRA). The aim of this study was to explore how patients with SMI experience a stay in CRA established in a City in Central Norway. A descriptive qualitative study with individual interviews and a group interview with 13 persons. The CRA aims to improve the discharge process from hospital to independent supported living by facilitating the establishment of health and social services and preparing the patients. The philosophy is to help patients use community resources by e.g. not offering any organized in-house activities. The main question in the interviews was "How have you experienced the stay at the CRA?" The interviews were analyzed with a thematic approach using systematic text condensation. The participants experienced the stay at the CRA "Like a hotel" but also boring, due to the lack of organized in-house activities. The patients generally said they were not informed about the philosophy of the CRA before the stay. The participants had to come up with activities outside the CRA and said they got active help from the staff to do so; some experienced this as positive, whereas others wanted more organized in-house activities like they were used to from mental health hospital stays. Participants described the staff in the CRA to be helpful and forthcoming, but they did not notice the staff being active in organizing the aftercare. The stay at the CRA was experienced as different from other services, with more freedom and focus on self-care, and lack of in-house activities. This led to increased self-activity among the patients, but some wanted more in-house activities. To prepare the patients better for the stay at the CRA, more information about the philosophy is needed in the pre

We compared the problems or complications associated with electrodiagnostic testing in 77 patients with implanted cardiac devices. Thirty tests were performed after magnet placement, and 47 were performed without magnet application. All electrodiagnostic tests were performed safely in all patients without any serious effect on the implanted cardiac devices with or without magnet placement. A significantly higher number of patient symptoms and procedure changes were reported in the magnet group (P magnet group patients had an approximately 11-fold greater risk of symptoms than those in the control group. Our data do not support a recommendation that magnet placement is necessary for routine electrodiagnostic testing in patients with implanted cardiac devices, as long as our general and specific guidelines are followed.

Early enteral nutrition has been shown to decrease complications and improve patient outcomes. Post pyloric feeding is recommended for patients with gastric intolerance or at high risk for aspiration. Feeding tube placement can be challenging and pose risk of pulmonary complications. Reliance on radiographic confirmation for feeding tube placement exposes the patient to radiation. Electromagnetic placement device (EMPD) may offer a method to minimize pulmonary complications, increase successful placement, and decrease radiation exposure to the patient. The purpose of this study was to evaluate the safety and efficacy of using EMPD verification, instead of routine abdominal radiographic confirmation, for small-bore feeding tube placement. Variables evaluated were adverse events, utilization of radiographs for confirmation, and success rate of feeding tube placement in the ordered location. Two time frames were reviewed. In a 1-year period, 3754 small-bore feeding tubes were placed using EMPD, with zero adverse events noted. Radiographic confirmation was utilized in 0%-29.2% of the EMPD placed tubes. Successful placement of feeding tubes using EMPD ranged from 94%-99.6%. During a 5-year period, 7081 EMPD feeding tubes were evaluated. One adverse event, pneumothorax, occurred during the placement of these 7081 tubes, for a rate of 0.014%. Feeding tube placement confirmation is safe and efficacious via EMPD providing an effective method of feeding tube placement with a success rate >94% into the desired location. EMPD is an accurate verification method of distal tip location, eliminating the need for routine abdominal radiographic confirmation. © 2018 American Society for Parenteral and Enteral Nutrition.

Hickman catheter inserter has previously been predominantly accomplished surgically by means of venous cutdown or percutaneous placement in the operating room. The authors describe their method and results for 55 consecutive percutaneous placements of Hickman catheters in the interventional radiology suite. Complication rates were comparable to those for surgical techniques. Radiologic placement resulted in increased convenience, decreased time and cost of insertion, and super fluoroscopic control of catheter placement and any special manipulations. Modern angiographic materials provide safer access to the subclavian vein than traditional methods. The authors conclude that radiologic placement of Hickman catheters offers significant advantages over traditional surgical placement

To determine whether the number of coils visualized in the uterotubal junction at the end of hysteroscopic microinsert placement predicts successful tubal occlusion. Cohort retrospective study (Canadian Task Force classification II-2). Department of obstetrics and gynecology in a teaching hospital. One hundred fifty-three women underwent tubal microinsert placement for permanent birth control from 2010 through 2014. The local institutional review board approved this study. Three-dimensional transvaginal ultrasound (3D TVU) was routinely performed 3 months after hysteroscopic microinsert placement to check position in the fallopian tube. The correlation between the number of coils visible at the uterotubal junction at the end of the hysteroscopic microinsert placement procedure and the device position on the 3-month follow-up 3D TVU in 141 patients was evaluated. The analysis included 276 microinserts placed during hysteroscopy. The median number of coils visible after the hysteroscopic procedure was 4 (interquartile range, 3-5). Devices for 30 patients (21.3%) were incorrectly positioned according to the 3-month follow-up 3D TVU, and hysterosalpingography was recommended. In those patients the median number of coils was in both the right (interquartile range, 2-4) and left (interquartile range, 1-3) uterotubal junctions. The number of coils visible at the uterotubal junction at the end of the placement procedure was the only factor that predicted whether the microinsert was well positioned at the 3-month 3D TVU confirmation (odds ratio, .44; 95% confidence interval, .28-.63). When 5 or more coils were visible, no incorrectly placed microinsert could be seen on the follow-up 3D TVU; the negative predictive value was 100%. No pregnancies were reported. The number of coils observed at the uterotubal junction at the time of microinsert placement should be considered a significant predictive factor of accurate and successful microinsert placement.

Full Text Available Approximately 5 million central venous catheters (CVCs are placed by physicians annually in the United States, with a complication rate of 15%.1 Guidelines and recommendations are continually being established and updated regarding CVC placement.2 While much has been done regarding training the technical skills of CVC placement using part-task trainers (i.e., mannequins, successfully finding and cannulating a central vein is but one part of the process. In fact, many steps designed to prevent untoward complications involve non-technical skills which are perhaps more important in training practitioners to safely place CVCs. First in aviation and now in healthcare, practitioners are being trained in realistic and highly interactive simulated environments so they can learn not just technical skills , but the key management and non-technical steps which make their task safer.3 One modality being used to improve performance is video gaming simulation, or "serious gaming." Gaming as a learning tool is being increasingly utilized in health care fields and can lead to better skill-based outcomes.4 As such, we have developed a game based around the placement of CVCs that will be used as a new teaching modality in a pilot program for instructing residents in safe CVC placement.

An important aim ofa treatment with single-unit and multi-unit fixed dental prostheses is a durable and profitable treatment outcome. That requires aftercare, too. First, the frequency of routine oral examinations should be assessed, using an individual risk profile. The objectives of the routine oral examinations are the prevention and, when necessary, the treatment of pathological conditions and complications. With regard to prevention, attention should be paid to information and instruction, oral biofilm and calculus, non-functional activities, hard tooth tissues, periodontal and peri-implant tissues, and saliva. Subsequently, it can be determined whether the intended durability and profitability have been achieved or can still be achieved, whether or not through indicated adjustments. Special attention should be paid to endodontically treated teeth. Restorative, repair or replacement treatments may be indicated in case ofcomplications, such as loose single- or multi-unitfixed dental prosthesis, fracture of a fixed dental prosthesis unit, lost tooth pulp vitality, tooth root fracture, and implant or implant abutment problems.

Donated media placements for public service announcements (PSAs) can be difficult to secure, and may not always reach intended audiences. Strategies used by the Centers for Disease Control and Prevention's (CDC) Screen for Life: National Colorectal Cancer Action Campaign (SFL) to obtain donated media placements include producing a diverse mix of high-quality PSAs, co-branding with state and tribal health agencies, securing celebrity involvement, monitoring media trends to identify new distribution opportunities, and strategically timing the release of PSAs. To investigate open-ended recall of PSAs promoting colorectal cancer screening, CDC conducted 12 focus groups in three U.S. cities with men and women either nearing age 50 years, when screening is recommended to begin, or aged 50-75 years who were not in compliance with screening guidelines. In most focus groups, multiple participants recalled exposure to PSAs promoting colorectal cancer screening, and most of these individuals reported having seen SFL PSAs on television, in transit stations, or on the sides of public buses. Some participants reported exposure to SFL PSAs without prompting from the moderator, as they explained how they learned about the disease. Several participants reported learning key campaign messages from PSAs, including that colorectal cancer screening should begin at age 50 years and screening can find polyps so they can be removed before becoming cancerous. Donated media placements can reach and educate mass audiences, including millions of U.S. adults who have not been screened appropriately for colorectal cancer.

To describe the process and challenges from a project that aimed to develop processes, source new placements and place students primarily in the discipline of nursing, but also occupational therapy, physiotherapy, podiatry, social work, and speech therapy. Clinical experience in health facilities is an essential element of health professional education, yet globally, there is a lack of clinical placements to meet demands. Educational providers are seeking placements in nontraditional facilities, yet little has been reported on the challenges in the process of procuring clinical placements. The project used a descriptive approach within a quality implementation framework. The project was guided by the quality implementation framework that included four critical steps: considerations of the host setting, structuring the implementation, supporting the implementation and improving future applications. A total of 115 new student placements were finalised across six health disciplines, including elderly care, nongovernment organisations and general practice. Sixty-two nursing students were placed in the new placements during the project. Challenges included communication, the time-consuming nature of the process and 'gatekeeping' blocks to obtaining placements. Recommendations included the importance of personal interaction in developing and maintaining relationships, and the need for clear communication processes and documentation. Potential areas for research are also given. There is great potential for growth in establishing new placements outside the traditional placement facilities for nursing and allied health and for expanding already existing nonhospital placements. Clinical professional experiences are essential to any nursing or allied health programme. There is an increasing demand for, and global lack of, clinical placements for nursing and allied health students. The results provide nursing and allied health educators and managers a framework for planning

Consultation with the filipino boarding home: an after-care facility in Hawaii.

Yutiao, M; Kinzie, J D

This report describes a unique Hawaiian after-care facility the Filipino operated boarding home, and the approaches useful in consultation with the operators. The majority of the boarding homes for psychiatric patients are operated by recent Filipino immigrants. This fact is explained by their current social position and also by cultural values--such as aiding others and an extended family system--which are present in the Philippines. In consultation with seventeen such boarding home operators, cultural beliefs and values played a great part in their approach to patients. These approaches created special problems and assets in their management of patients from other ethnic groups such as Japanese, Caucasian and Hawaiian. A problem-oriented approach to consultation proved useful initially and set the stage for other forms of intervention. This included allowing the operator to ventilate her feelings about the patient; bridging the communication gap between operators and patients; dissipating the operators' stereotypic perception of patients; and educating the operators about mental illness. Our impressions and indirect evidence indicated that Filipino boarding home operators perform a useful service and, with consultation sensitive to their values, can become even more effective.

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.

Pre-school children placed in local authority care show elevated rates of mental health disorders when compared to the general population. This study investigated risk factors for mental health disorders relating to the period prior to entering care and while in care. A representative sample of 43 children in care aged 0-72 months in an inner London borough underwent comprehensive multidimensional assessments. Presence of emotional, behavioural, attachment and adaptive disorders was ascertained. Exposure to two pre-placement risk factors and six placement risk factors was compared between children with and without a disorder. A total of 26 children (60.5%) had at least one mental health disorder. The two pre-placement risk factors, multiple types of maltreatment and entry into care after the age of 6 months, were both significantly associated with mental health disorders. The three placement risk factors of sudden placement moves, multiple placement moves and child-carer alienation showed a significant association with mental health disorders. There was a strong correlation between the number of risk factors and the number of co-morbid mental health disorders per child (r = .67, p school mental health. © The Author(s) 2014.

Clinical outcomes of self-expandable metal stent (SEMS placement as palliative treatment for malignant colorectal obstruction: A single-center study from Japan

Directory of Open Access Journals (Sweden)

Toshikatsu Nitta

2017-07-01

Conclusion: SEMS placement as a palliative treatment is likely to fail within a year, leading to re-occlusion. It is very important to maintain vigilant monitoring using X-ray, CT, and colonoscopy after SEMS placement, with close cooperation between the endoscopist and surgeon. A logistic framework involving careful follow-up, even in the absence of symptoms, and a combined team involving endoscopists and surgeons should be established to support re-intervention and surgery. We recommend vigilant monitoring of patients who received SEMS placement for palliation of malignant colorectal obstruction.

Product Placement in Cartoons

Full Text Available Product placement is a marketing approach for integrating products or services into selected media content. Studies have shown that the impact of advertising on children and youth are large, and that it can affect their preferences and attitudes. The aim of this article is to determine the existing level of product placement in cartoons that are broadcast on Croatian television stations. Content analysis of cartoons in a period of one month gave the following results: in 30% of cartoons product placement was found; most product placement were visual ads, in 89%, however, auditory product placement and plot connection was also found. Most ads were related to toys and it is significant that even 65% of cartoons are accompanied by a large amount of products available on the Croatian market. This is the result of two sales strategies: brand licensing (selling popular cartoon characters to toys, food or clothing companies and cartoon production based on existing line of toys with the sole aim of making their sales more effective.

Objectives: This study evaluated the placements as a learning experience from the perspectives of past students and community stakeholders. Methods: A total of 32 projects were randomly selected out of 232 projects undertaken during 2006, 2008 and 2009. Two students and a stakeholder involved with each project were sampled. A standardised survey was emailed to students and in-depth interviews were held with stakeholders. Results: Fifty two per cent of 64 students and 57% of 25 stakeholders responded. Most students felt that the placements enhanced their academic experience and confidence in research skills, and were an effective form of learning. Perceived challenges included time constraints and, for a minority, inadequately prepared settings and stakeholders. Stakeholders felt that the placements empowered the communities and prepared students for the realities of working as a medical professional. They viewed students as a valuable resource and believed that student projects addressed important community myths and health problems. Recommendations from students and stakeholders included more time for the Public Health block, followup interventions for greater continuity, and better alignment of projects with stakeholder programmes. Conclusion: The evaluation reveals both the importance and challenges of community placements and identifies areas of improvement. Despite the limited duration of the placements, they offered valuable community-based learning experiences for the students and worthwhile benefits for the communities.

A format for phylogenetic placements.

Directory of Open Access Journals (Sweden)

Frederick A Matsen

Full Text Available We have developed a unified format for phylogenetic placements, that is, mappings of environmental sequence data (e.g., short reads into a phylogenetic tree. We are motivated to do so by the growing number of tools for computing and post-processing phylogenetic placements, and the lack of an established standard for storing them. The format is lightweight, versatile, extensible, and is based on the JSON format, which can be parsed by most modern programming languages. Our format is already implemented in several tools for computing and post-processing parsimony- and likelihood-based phylogenetic placements and has worked well in practice. We believe that establishing a standard format for analyzing read placements at this early stage will lead to a more efficient development of powerful and portable post-analysis tools for the growing applications of phylogenetic placement.

1998-07-01

Objective. The purpose of this study is to determine the risk of CNS and/or peritoneal infection in children with ventriculoperitoneal shunts in whom a percutaneous gastrostomy tube is placed. Materials and methods. We placed 205 gastrostomy or gastrojejunostomy tubes from January of 1991 to December 1996. Twenty-three patients (10 boys, 13 girls) had ventriculoperitoneal shunts at the time of placement. All shunts were placed at least 1 month prior to placement of the gastrostomy tube. The patients ranged in age from 8 months to 16 years with a mean age of 6 years, 9 months. Patient weight ranged from 2 kg to 60 kg. All 23 children required long-term nutritional support due to severe neurologic impairment. No prophylactic antibiotics were given prior to the procedure. Of the patients, 21/23 had a 14-F Sacks-Vine gastrostomy tube with a fixed terminal retention device inserted, using percutaneous fluoroscopic antegrade technique. Two of the 23 patients had a Ross 14-F Flexi-flo gastrostomy tube which required a retrograde technique due to a small caliber esophagus in these children. Results. All 23 children had technically successful placements of percutaneous gastrostomy (7) or gastrojejunostomy (16) tubes. Of the children, 21/23 (91 %) had no complications from the procedure. Two of 23 (9 %) patients demonstrated signs of peritonitis after placement of their gastrostomy tubes and subsequently had shunt infections. In both, children CSF culture grew gram-positive cocci. The antegrade technique was used in both children who developed peritonitis. Conclusion. Our study indicates children with ventriculoperitoneal shunts who undergo percutaneous gastrostomy are at greater risk for infection and subsequent shunt malfunction. Therefore, we recommend prophylactic antibiotic therapy to cover for skin and oral flora. (orig.) With 1 fig., 7 refs.

Camp, Meghan A; Barner, John R; Okech, David

2018-01-01

The trafficking of persons is one of the most egregious violations of human rights in modern society. Given the disproportionate effects across demographic categories of age and gender, as well as concentrated impacts within the developing world, there is a strong need for research and literature on program effectiveness and appropriate aftercare efforts for those persons whose lives and livelihoods have been impacted by trafficking. The purpose of this article is to provide a scoping review of what is known about effectively helping survivors of human trafficking experiencing lack of economic opportunity and the implications for practice and future research regarding the absence of literature. From over 14,000 initial search results, this article focuses on those initiatives (N = 16) that support economic development of the individual or family after being trafficked. Implications arising from the review for trafficking policy, areas for further research, and implications for practitioners are highlighted and discussed.

ESL Placement and Schools

Callahan, Rebecca; Wilkinson, Lindsey; Muller, Chandra; Frisco, Michelle

2010-01-01

In this study, the authors explore English as a Second Language (ESL) placement as a measure of how schools label and process immigrant students. Using propensity score matching and data from the Adolescent Health and Academic Achievement Study and the National Longitudinal Study of Adolescent Health, the authors estimate the effect of ESL placement on immigrant achievement. In schools with more immigrant students, the authors find that ESL placement results in higher levels of academic performance; in schools with few immigrant students, the effect reverses. This is not to suggest a one-size-fits-all policy; many immigrant students, regardless of school composition, generational status, or ESL placement, struggle to achieve at levels sufficient for acceptance to a 4-year university. This study offers several factors to be taken into consideration as schools develop policies and practices to provide immigrant students opportunities to learn. PMID:20617111

To retrospectively evaluate the technical success of computed tomography fluoroscopy-guided short hookwire placement before video-assisted thoracoscopic surgery and to identify the risk factors for initial placement failure. In total, 401 short hookwire placements for 401 lesions (mean diameter 9.3 mm) were reviewed. Technical success was defined as correct positioning of the hookwire. Possible risk factors for initial placement failure (i.e., requirement for placement of an additional hookwire or to abort the attempt) were evaluated using logistic regression analysis for all procedures, and for procedures performed via the conventional route separately. Of the 401 initial placements, 383 were successful and 18 failed. Short hookwires were finally placed for 399 of 401 lesions (99.5%). Univariate logistic regression analyses revealed that in all 401 procedures only the transfissural approach was a significant independent predictor of initial placement failure (odds ratio, OR, 15.326; 95% confidence interval, CI, 5.429-43.267; p < 0.001) and for the 374 procedures performed via the conventional route only lesion size was a significant independent predictor of failure (OR 0.793, 95% CI 0.631-0.996; p = 0.046). The technical success of preoperative short hookwire placement was extremely high. The transfissural approach was a predictor initial placement failure for all procedures and small lesion size was a predictor of initial placement failure for procedures performed via the conventional route. • Technical success of preoperative short hookwire placement was extremely high. • The transfissural approach was a significant independent predictor of initial placement failure for all procedures. • Small lesion size was a significant independent predictor of initial placement failure for procedures performed via the conventional route.

Alpine, Lucy M; Caldas, Francieli Tanji; Barrett, Emer M

2018-04-02

The objective of the study was to investigate student and practice educator evaluations of practice placements using a structured 2 to 1 supervision and implementation model. Cross-sectional pilot study set in clinical sites providing placements for physiotherapy students in Ireland. Students and practice educators completing a 2.1 peer placement between 2013 and 2015 participated. A self-reported questionnaire which measured indicators linked to quality assured placements was used. Three open-ended questions captured comments on the benefits and challenges associated with the 2 to 1 model. Ten students (10/20; 50% response rate) and 10 practice educators (10/10; 100% response rate) responded to the questionnaire. Student responses included four pairs of students and one student from a further two pairs. There was generally positive agreement with the questionnaire indicating that placements using the 2 to 1 model were positively evaluated by participants. There were no significant differences between students and practice educators. The main benefits of the 2 to 1 model were shared learning experiences, a peer supported environment, and the development of peer evaluation and feedback skills by students. A key component of the model was the peer scripting process which provided time for reflection, self-evaluation, and peer review. 2 to 1 placements were positively evaluated by students and educators when supported by a structured supervision model. Clear guidance to students on the provision of peer feedback and support for educators providing feedback to two different students is recommended.

Exploring whether student nurses report poor practice they have witnessed on placements.

Science.gov (United States)

Bellefontaine, Nerys

While literature suggests that nurses report incidents or potentially unsafe care delivery, there is little evidence on student nurses' practice in this area. To explore the factors that influence student in reporting concerns about practice. A qualitative study was carried out using a phenomenological approach, based on semi-structured interviews with six student nurses. Student nurses said they do not always report potentially unsafe practice they have witnessed. Four main themes were identified: the student-mentor relationship in clinical placement; actual or potential support provided by both the practice area and university; students' own personal confidence and professional knowledge base; and fear of failing clinical placements. The nursing profession needs to take stock of current organisational culture and practice, and address issues around reporting in practice. Recommendations are made to improve mentorship, nurse training and for further research.

Medical education in community settings is an essential ingredient of doctors' training and a key factor in recruiting general practitioners (GP). Health Education England's report 'Broadening the Foundation' recommends foundation doctors complete 4-month community placements. While Foundation GP schemes exist; other community settings, are not yet used for postgraduate training. The objective of this study was to explore how community-based training of junior doctors might be expanded into possible 'innovative community education placements' (ICEPs), examining opportunities and barriers to these developments. A qualitative study where semistructured interviews were undertaken and themes were generated deductively from the research questions, and iteratively from transcripts. UK community healthcare. Stakeholders from UK Community healthcare providers and undergraduate GP and community educators. Nine participants were interviewed; those experienced in delivering community-based undergraduate education, and others working in community settings that had not previously trained doctors. Themes identified were practicalities such as 'finance and governance', 'communication and interaction', 'delivery of training' and 'perceptions of community'. ICEPs were willing to train Foundation doctors. However, concerns were raised that large numbers and inadequate resources could undermine the quality of educational opportunities, and even cause reputational damage. Organisation was seen as a challenge, which might be best met by placing some responsibility with trainees to manage their placements. ICEP providers agreed that defined service contribution by trainees was required to make placements sustainable, and enhance learning. ICEPs stated the need for positive articulation of the learning value of placements to learners and stakeholders. This study highlighted the opportunities for foundation doctors to gain specialist and generalist knowledge in ICEPs from diverse clinical

Improving the input of people with mental illness into their recovery plans can potentially lead to better outcomes. In the present study, we evaluated the introduction of motivational aftercare planning (MAP) into the discharge planning of psychiatric inpatients. MAP is a manualized intervention combining motivational interviewing with advance directives. We measured changes in the level of patient input into discharge planning following training staff in the use of MAP. This included the following: (i) documentation of early relapse signs along with successful past responses; (ii) evidence of aftercare planning; and (iii) the use of the patients' own words in the plan. We used a ward-level controlled before-and-after design comparing one intervention ward with two control wards. We used anonymized recovery plans, with a goal of 50 plans per ward before and after the intervention, to look for evidence of patient input into care planning with a standardized checklist. There were also qualitative interviews with individuals discharged from the unit. We reviewed 100 intervention ward plans and 197 control ones (total n = 297). There were no significant differences in recovery plans from intervention and control wards at baseline. Following MAP training, the intervention ward improved significantly (e.g. identification of triggers increased from 52 to 94%, χ 2  = 23.3, d.f. =1, P < 0.001). This did not occur in the control wards. The qualitative data (n = 20 interviews) showed improvements in participants' experiences of discharge planning. MAP increased inpatient input into discharge planning and was valued by participants. The effect on subsequent health service use needs evaluation. © 2016 Australian College of Mental Health Nurses Inc.

Placement suitability criteria of composite tape for mould surface in automated tape placement

Directory of Open Access Journals (Sweden)

Zhang Peng

2015-10-01

Full Text Available Automated tape placement is an important automated process used for fabrication of large composite structures in aeronautical industry. The carbon fiber composite parts realized with this process tend to replace the aluminum parts produced by high-speed machining. It is difficult to determine the appropriate width of the composite tape in automated tape placement. Wrinkling will appear in the tape if it does not suit for the mould surface. Thus, this paper deals with establishing placement suitability criteria of the composite tape for the mould surface. With the assumptions for ideal mapping and by applying some principles and theorems of differential geometry, the centerline trajectory of the composite tape is identified to follow the geodesic. The placement suitability of the composite tape is examined on three different types of non-developable mould surfaces and four criteria are derived. The developed criteria have been used to test the deposition process over several mould surfaces and the appropriate width for each mould surface is obtained by referring to these criteria.

Ultrasound-guided needle placement is a key step in a lot of radiological intervention procedures such as biopsy, local anesthesia and fluid drainage. To help training future intervention radiologists, we develop a serious game to teach the skills involved. We introduce novel techniques for realistic simulation and integrate game elements for active and effective learning. This game is designed in the context of needle placement training based on the some essential characteristics of serious games. Training scenarios are interactively generated via a block-based construction scheme. A novel example-based texture synthesis technique is proposed to simulate corresponding ultrasound images. Game levels are defined based on the difficulties of the generated scenarios. Interactive recommendation of desirable insertion paths is provided during the training as an adaptation mechanism. We also develop a fast physics-based approach to reproduce the shadowing effect of needles in ultrasound images. Game elements such as time-attack tasks, hints and performance evaluation tools are also integrated in our system. Extensive experiments are performed to validate its feasibility for training.

2017-11-17

Objectives : The Quebec Youth Protection Act was amended in 2007. The main goal of this reform was to improve placement stability for children who are removed from their home for their protection. Among several legal provisions introduced was the establishment of maximum age-specific durations of out-of-home care, after which a plan must be established to provide stability for children placed in substitute care by finding permanent homes for them. The purpose of this study is (1) to examine trends in placement use and placement stability since the reform and (2) to document the current frequency of each type of placement setting, the cumulative time in care before the exit to permanency, and the sustainability of the permanency outcome. Methods: The study relies on 3 entry cohorts of all children investigated who received protection measures in the province of Quebec during 3 specific time frames before and after the reform ( n = 9620, 8676, 8425). Cohorts were observed for a period varying from 3 to 4 years. Administrative data from all 16 child protection agencies were used to track placement trajectory indicators and to compare cohorts. Results : There has been a decrease in the proportion of children receiving protection measures who were placed in care since the reform, and placement in kinship care has become more frequent among children placed. Placement stability improved slightly after the reform. Overall, for infants, the most frequent type of permanency attained is adoption, while reunification is the option most often indicated for older children. Some children are at a greater risk of experiencing unstable placement trajectories: young children have a high rate of reunification breakdown, some wait a long time to be adopted, and adolescents are frequently removed from the substitute care setting where they were supposed to stay until the age of 18. Conclusions : The results suggest interesting avenues for policy makers and service providers to improve

Schauer, Steven G; April, Michael D; Naylor, Jason F; Simon, Erica M; Fisher, Andrew D; Cunningham, Cord W; Morissette, Daniel M; Fernandez, Jessie Renee D; Ryan, Kathy L

Thoracic trauma represents 5% of all battlefield injuries. Communicating pneumothoraces resulting in tension physiology remain an important etiology of prehospital mortality. In addressing penetrating chest trauma, current Tactical Combat Casualty Care (TCCC) guidelines advocate the immediate placement of a vented chest seal device. Although the Committee on TCCC (CoTCCC) has approved numerous chest seal devices for battlefield use, few data exist regarding their use in a combat zone setting. To evaluate adherence to TCCC guidelines for chest seal placement among personnel deployed to Afghanistan. We obtained data from the Prehospital Trauma Registry (PHTR). Joint Trauma System personnel linked patients to the Department of Defense Trauma Registry, when available, for outcome data upon reaching a fixed facility. In the PHTR, we identified 62 patients with documented gunshot wound (GSW) or puncture wound trauma to the chest. The majority (74.2%; n = 46) of these were due to GSW, with the remainder either explosive-based puncture wounds (22.6%; n = 14) or a combination of GSW and explosive (3.2%; n = 2). Of the 62 casualties with documented GSW or puncture wounds, 46 (74.2%) underwent chest seal placement. Higher proportions of patients with medical officers in their chain of care underwent chest seal placement than those that did not (63.0% versus 37.0%). The majority of chest seals placed were not vented. Of patients with a GSW or puncture wound to the chest, 74.2% underwent chest seal placement. Most of the chest seals placed were not vented in accordance with guidelines, despite the guideline update midway through the study period. These data suggest the need to improve predeployment training on TCCC guidelines and matching of the Army logistical supply chain to the devices recommended by the CoTCCC. 2017.

Two-Phase Algorithm for Optimal Camera Placement

Directory of Open Access Journals (Sweden)

Jun-Woo Ahn

2016-01-01

Full Text Available As markers for visual sensor networks have become larger, interest in the optimal camera placement problem has continued to increase. The most featured solution for the optimal camera placement problem is based on binary integer programming (BIP. Due to the NP-hard characteristic of the optimal camera placement problem, however, it is difficult to find a solution for a complex, real-world problem using BIP. Many approximation algorithms have been developed to solve this problem. In this paper, a two-phase algorithm is proposed as an approximation algorithm based on BIP that can solve the optimal camera placement problem for a placement space larger than in current studies. This study solves the problem in three-dimensional space for a real-world structure.

Transaxillary Subpectoral Placement of Cardiac Implantable Electronic Devices in Young Female Patients

Directory of Open Access Journals (Sweden)

Joo Hyun Oh

2017-01-01

Full Text Available BackgroundThe current indications of cardiac implantable electronic devices (CIEDs have expanded to include young patients with serious cardiac risk factors, but CIED placement has the disadvantage of involving unsightly scarring and bulging of the chest wall. A collaborative team of cardiologists and plastic surgeons developed a technique for the subpectoral placement of CIEDs in young female patients via a transaxillary approach.MethodsFrom July 2012 to December 2015, subpectoral CIED placement via an axillary incision was performed in 10 young female patients, with a mean age of 25.9 years and mean body mass index of 20.1 kg/m2. In the supine position, with the patient's shoulder abducted, an approximately 5-cm linear incision was made along one of the deepest axillary creases. The submuscular plane was identified at the lateral border of the pectoralis major, and the dissection continued over the clavipectoral fascia until the subpectoral pocket could securely receive a pulse generator. Slight upward dissection also exposed an entrance to the subclavian vein, allowing the cardiology team to gain access to the vein. One patient with dilated cardiomyopathy underwent augmentation mammoplasty and CIED insertion simultaneously.ResultsOne case of late-onset device infection occurred. All patients were highly satisfied with the results and reported that they would recommend the procedure to others.ConclusionsWith superior aesthetic outcomes compared to conventional methods, the subpectoral placement of CIEDs via a transaxillary approach is an effective, single-incision method to hide operative scarring and minimize bulging of the device, and is particularly beneficial for young female or lean patients.

An experiment was carried out on the bachelor's degree course in nursing with two new clinical placement concepts: workplace learning and the dedicated education centre. The aim was to establish a learning culture that creates a sufficiently high learning performance for students. The objectives of this study are threefold: (1) to look for a difference in the "learning culture" and "learning performance" in traditional clinical placement departments and the new clinical placement concepts, the "dedicated education centre" and "workplace learning"; (2) to assess factors influencing the learning culture and learning performance; and (3) to investigate whether there is a link between the learning culture and the learning performance. A non-randomised control study was carried out. The experimental group consisted of 33 final-year nursing undergraduates who were following clinical placements at dedicated education centres and 70 nursing undergraduates who undertook workplace learning. The control group consisted of 106 students who followed a traditional clinical placement. The "learning culture" outcome was measured using the Clinical Learning Environment, Supervision and Nurse Teacher scale. The "learning performance" outcome consisting of three competencies was measured using the Nursing Competence Questionnaire. The traditional clinical placement concept achieved the highest score for learning culture (plearning performance of which the dedicated education centres achieved the highest scores. The 3 clinical placement concepts showed marked differences in learning performance for the "assessment" competency (plearning can be seen as complementary clinical placement concepts. The organisation of clinical placements under the dedicated education centre concept and workplace learning is recommended for final-year undergraduate nursing students.

Lam, Elaine; Chan, Tiffany; Wiseman, Sam M

2014-07-01

Literature review was carried out and studies reporting on treatment of breast abscesses were critically appraised for quality and their level of evidence using the Strength of Recommendation Taxonomy guidelines, and key recommendations were summarized. Needle aspiration either with or without ultrasound guidance should be employed as first line treatment of breast abscesses. This approach has the potential benefits of: superior cosmesis, shorter healing time, and avoidance of general anaesthesia. Multiple aspiration sessions may be required for cure. Ultrasound-guided percutaneous catheter placement may be considered as an alternative approach for treatment of larger abscesses (>3 cm). Surgical incision and drainage should be considered for first line therapy in large (>5 cm), multiloculated, or long standing abscesses, or if percutaneous drainage is unsuccessful. All patients should be treated concurrently with antibiotics. Patients with recurrent subareolar abscesses and fistulas should be referred for consideration of surgical treatment.

Optimal DG placement in deregulated electricity market

International Nuclear Information System (INIS)

Gautam, Durga; Mithulananthan, Nadarajah

2007-01-01

This paper presents two new methodologies for optimal placement of distributed generation (DG) in an optimal power flow (OPF) based wholesale electricity market. DG is assumed to participate in real time wholesale electricity market. The problem of optimal placement, including size, is formulated for two different objectives, namely, social welfare maximization and profit maximization. The candidate locations for DG placement are identified on the basis of locational marginal price (LMP). Obtained as lagrangian multiplier associated with active power flow equation for each node, LMP gives the short run marginal cost (SRMC) of electricity. Consumer payment, evaluated as a product of LMP and load at each load bus, is proposed as another ranking to identify candidate nodes for DG placement. The proposed rankings bridges engineering aspects of system operation and economic aspects of market operation and act as good indicators for the placement of DG, especially in a market environment. In order to provide a scenario of variety of DGs available in the market, several cost characteristics are assumed. For each DG cost characteristic, an optimal placement and size is identified for each of the objectives. The proposed methodology is tested in a modified IEEE 14 bus test system. (author)

Full Text Available Percutaneous endoscopic gastrostomy (PEG has been used for providing enteral access to patients who require long-term enteral nutrition for years. Although generally considered safe, PEG tube placement can be associated with many immediate and delayed complications. Buried bumper syndrome (BBS is one of the uncommon and late complications of percutaneous endoscopic gastrostomy (PEG placement. It occurs when the internal bumper of the PEG tube erodes into the gastric wall and lodges itself between the gastric wall and skin. This can lead to a variety of additional complications such as wound infection, peritonitis, and necrotizing fasciitis. We present here a case of buried bumper syndrome which caused extensive necrosis of the anterior abdominal wall.

2013-12-01

The increase of the base transceiver station (BTS) in most urban areas can be traced to the drive by network providers to meet demand for coverage and capacity. In traditional network planning, the final decision of BTS placement is taken by a team of radio planners, this decision is not fool proof against regulatory requirements. In this paper, an intelligent based algorithm for optimal BTS site placement has been proposed. The proposed technique takes into consideration neighbour and regulation considerations objectively while determining cell site. The application will lead to a quantitatively unbiased evaluated decision making process in BTS placement. An experimental data of a 2km by 3km territory was simulated for testing the new algorithm, results obtained show a 100% performance of the neighbour constrained algorithm in BTS placement optimization. Results on the application of GA with neighbourhood constraint indicate that the choices of location can be unbiased and optimization of facility placement for network design can be carried out.

Taylor, Jane A; Hayes, Melanie J; Wallace, Linda

2012-05-01

While placements in external locations are being increasingly used in dental education globally, few studies have explored the student learning experience at such placements. The purpose of this study was to investigate student experiences while on external placement in a baccalaureate dental hygiene program. A self-reporting questionnaire was distributed to final-year dental hygiene students (n=77) at the University of Newcastle, Australia, in 2010. The questionnaire included questions regarding the type of placement, experiences offered, supervision, resources available, and lasting impressions. Responding students were generally positive about their external placement experience and indicated that the majority of facilities provided them with the opportunity to provide direct patient care and perform clinical tasks typical of a practicing hygienist. However, there was a statistically significant difference in their opinions about discipline-focused and community placements. Students indicated that their external placement experience provided opportunities to learn more about time and patient management, including hands-on experience with specific clinical tasks. Ongoing evaluations are necessary to ensure that external placements meet both student needs and intended learning outcomes within dental hygiene programs.

Kassa, Biniyam Asmare

2013-01-01

This paper reports a linear programming approach for placement of applicants to study programs developed and implemented at the college of Business & Economics, Bahir Dar University, Bahir Dar, Ethiopia. The approach is estimated to significantly streamline the placement decision process at the college by reducing required man hour as well as the time it takes to announce placement decisions. Compared to the previous manual system where only one or two placement criteria were considered, the new approach allows the college's management to easily incorporate additional placement criteria, if needed. Comparison of our approach against manually constructed placement decisions based on actual data for the 2012/13 academic year suggested that about 93 percent of the placements from our model concur with the actual placement decisions. For the remaining 7 percent of placements, however, the actual placements made by the manual system display inconsistencies of decisions judged against the very criteria intended to guide placement decisions by the college's program management office. Overall, the new approach proves to be a significant improvement over the manual system in terms of efficiency of the placement process and the quality of placement decisions.

Implant by definition "means any object or material, such as an alloplastic substance or other tissue, which is partial or completely inserted into the body for therapeutic, diagnostic, prosthetic, or experimental purpose." The placement of a dental implant in an extraction socket at the time of extraction or explantation is known as immediate implant placement whereas delayed placement of implant signifies the implant placement in edentulous areas where healing has completed with new bone formation after the loss of tooth/teeth. Recent idea goes by "why late when it can be done immediately." There are several advantages of immediate placement of implants, and lots of studies have been done. In this article, the advantages and disadvantages of immediate versus delayed placement of implants have been reviewed.

International clinical placements provide undergraduate students with a unique and complex clinical learning environment, to explore cultural awareness, experience different health care settings and achieve clinical competencies. Higher education institutions need to consider how to structure these placements to ensure appropriate and achievable aims and learning outcomes. In this study we described the structure, aims and learning outcomes associated with international clinical placement opportunities currently undertaken by Australian undergraduate nursing students in the Asia region. Forty eight percent (n = 18) of the institutions invited responded. Eight institutions met the inclusion criteria, one of which offered three placements in the region, resulting in 10 international placements for which data were provided. An online survey tool was used to collect data during August and September 2015 on international clinical placements conducted by the participating universities. Descriptive data on type and numbers of placements is presented, along with results from the content analysis conducted to explore data from open ended questions on learning aims and outcomes. One hundred students undertook 10 International Clinical Placements offered in the Asian region by eight universities. Variations across placements were found in the length of placement, the number of students participating, facilitator to student ratios and assessment techniques used. Five categories related to the aims of the programs were identified: 'becoming culturally aware through immersion', 'working with the community to promote health', 'understanding the role of nursing within the health care setting', 'translating theory into professional clinical practice', and 'developing relationships in international learning environments'. Four categories related to learning outcomes were identified: 'understanding healthcare and determinants of health', 'managing challenges', 'understanding the

Full Text Available Objectives: The purpose of this research was to evaluate the effect of immediate placement of different restorative materials in comparison with a temporary restoration on the surface microhardness of mineral trioxide aggregate (MTA.Materials and Methods: Access cavities were prepared in 40 extracted human molars, and a 3-mm layer of MTA was placed in the pulp chamber. The samples were divided into eight groups (n=5. Ten minutes after the MTA placement, two groups were restored with Zonalin temporary restoration, while the other six groups were restored with glass-ionomer cement (GIC, resin-modified glass-ionomer (RMGI, or resin-based composite. In each group, the Vickers microhardness (VMH of MTA was determined after 7 and 21 days. Data were entered into SPSS 17 software program and were analyzed by two-way analysis of variance (ANOVA. The significance level was set at 5%.Results: The type of restorative materials had a statistically significant effect on the microhardness of MTA (P=0.002. However, the microhardness of MTA was neither significantly influenced by the timing of final restoration (P=0.246 nor by the time-material interaction (P=0.116.Conclusions: Based on the results of the present study and by considering the limitations of laboratory studies, it is recommended to postpone the placement of final restorations until the underlying MTA is completely set. Otherwise, in the clinical conditions in which early covering of MTA is recommended, sufficient moist-curing and hydration should be guaranteed by selecting a restorative material with the lowest hydrophilic interaction energy.

Ogbu, S.O.I.

2008-01-01

Purpose: To assess undergraduate radiography student perception of clinical placements and to evaluate their clinical learning experiences. Methods: To evaluate student perception of clinical placements, a Likert-scale questionnaire was used to assess clinical practice, the practice-learning environment. One hundred and seventy-eight undergraduate [student] radiographers participated in the study. Results: The students indicated they had adequate and enjoyed their time on the clinical placement. They also indicated the qualified staff was supportive, friendly and approachable. The students were able to achieve their learning outcomes during the placement. However placement venues, according to the students, had inadequate learning resources. No radiographic/medical imaging research findings, whether locally generated or otherwise, were used in clinical practice. Conclusions: Clinical placements had adequate student support. It provided a pleasant learning experience for the students and it enhanced their skills. Staff was willing and available to assist learning. Nevertheless, the training institutions, professional body and clinical placement providers need to make an effort to address inadequate learning resources (e.g. IT, library, study rooms) as well as the non-utilization of radiographic/medical imaging research findings

Delayed bracket placement in orthodontic treatment

Directory of Open Access Journals (Sweden)

Chandra Wigati

2008-12-01

Full Text Available Background: Beside bracket position, the timing of bracket placement is one of the most essential in orthodontic treatment with fixed appliances. Even it seems simple the timing of bracket placement can be crucial and significantly influence the result of orthodontic treatment. However it is often found brackets are placed without complete understanding of its purpose and effects, which could be useless and even detrimental for the case. Purpose: The aim of this case report is to show that the timing of bracket placement could be different depending on the cases. Case: Five different cases are presented here with different timing of bracket placement. Case management: On these cases, brackets were placed on the upper arch first, on the lower arch first, or even only on some teeth first. Good and efficient orthodontic treatment results were achieved. Conclusion: For every orthodontic case, from the very beginning of treatment, bracket should be placed with the end result in mind. If brackets are correctly placed at a correct time, better treatment result could be achieved without unnecessary round tripping tooth movement.

A Sea-of-Gates Style FPGA Placement Algorithm

Directory of Open Access Journals (Sweden)

Kalapi Roy

1996-01-01

Full Text Available Field Programmable Gate Arrays (FPGAs have a pre-defined chip boundary with fixed cell locations and routing resources. Placement objectives for flexible architectures (e.g., the standard cell design style such as minimization of chip area do not reflect the primary placement goals for FPGAs. For FPGAs, the layout tools must seek 100% routability within the architectural constraints. Routability and congestion estimates must be made directly based on the demand and availability of routing resources for detailed routing of the particular FPGA. We. present a hierarchical placement approach consisting of two phases: a global placement phase followed by a detailed placement phase. The global placement phase minimizes congestion estimates of the global routing regions and satisfies all constraints at a coarser level. The detailed placer seeks to maximize the routability of the FPGA by considering factors which cause congestion at the detailed routing level and to precisely satisfy all of the constraints. Despite having limited knowledge about the gate level architectural details, we have achieved a 90%reduction in the number of unrouted nets in comparison to an industrial tool (the only other tool developed specifically for this architecture.

Outpatient departments of 4 teaching hospitals in the Netherlands. Eleven hundred forty-five women who underwent hysteroscopic sterilization using the Essure device between March 2005 and December 2007. Transvaginal ultrasound examination 12 weeks after uncomplicated successful bilateral placement or as indicated according to the transvaginal ultrasound protocol after 4 weeks, and hysterosalpingography (HSG) at 12 weeks to confirm correct placement of the device after 3 months. The rate of successful placement was 88.4% initially. In 164 women (15%), successful placement was confirmed at HSG according the protocol. In 9 patients (0.84%), incorrect position of the device was observed at HSG. The cumulative pregnancy rate after 18 months was 3.85 per thousand women. Transvaginal ultrasound should be the first diagnostic test used to confirm the adequacy of hysteroscopic Essure sterilization because it is minimally invasive, averts ionizing radiation, and does not decrease the effectiveness of the Essure procedure.

Hickey, M.J.

1997-01-01

Impacted material placement plans (IMPP) are documents identifying the essential elements in placing remediation wastes into disposal facilities. Remediation wastes or impacted material(s) are those components used in the construction of the disposal facility exclusive of the liners and caps. The components might include soils, concrete, rubble, debris, and other regulatory approved materials. The IMPP provides the details necessary for interested parties to understand the management and construction practices at the disposal facility. The IMPP should identify the regulatory requirements from applicable DOE Orders, the ROD(s) (where a part of a CERCLA remedy), closure plans, or any other relevant agreements or regulations. Also, how the impacted material will be tracked should be described. Finally, detailed descriptions of what will be placed and how it will be placed should be included. The placement of impacted material into approved on-site disposal facilities (OSDF) is an integral part of gaining regulatory approval. To obtain this approval, a detailed plan (Impacted Material Placement Plan [IMPP]) was developed for the Fernald OSDF. The IMPP provides detailed information for the DOE, site generators, the stakeholders, regulatory community, and the construction subcontractor placing various types of impacted material within the disposal facility

A one of the greatest concerns with orthodontic mini-implants is risk of injury to dental roots during placement is, especially when they are inserted between teeth. Many techniques have been used to facilitate safe placement of interradicular miniscrews. Brass Wires or metallic markers are easy to place in the interproximal spaces, but because their relative positions may be inconsistent in different radio -graphic views, they are not always accurate. K.S. micro implant placement guide suggested in this article is simple design and easy in fabrication, required minimal equipment for fabrication and does not disturb the existing appliance system, clearly located in the radiograph and the mini-screw can be easily inserted through the guide reducing the chance of implant misplacement.

Placement education pedagogy as social participation: what are students really learning?

2014-03-01

This paper draws on empirical fieldwork data of naturally occurring UK physiotherapy placement education to make visible how education is actually carried out and suggest what students may be learning through their placement interactions. The data challenge everyone involved in placement education design and practice to consider the values and practices students are learning to perpetuate through placement education experiences. The researcher undertook an ethnomethodologically informed ethnographic observation of naturally occurring physiotherapy placement education in two UK NHS placement sites. This study adopted a social perspective of learning to focus on the minutiae of placement educator, student and patient interaction practices during student-present therapeutic activities. Two days of placement for each of six senior students were densely recorded in real-time focussing specifically on the verbal, kinesics and proxemics-based elements of the participants' interaction practices. Repeated cycles of data analysis suggested consistent practices irrespective of the placement, educators, students or patients. The data suggest that placement education is a powerful situated learning environment in which students see, experience and learn to reproduce the physiotherapy practices valued by the local placement. Consistently, placement educators and students co-produced patient-facing activities as spectacles of physiotherapy-as-science. In each setting, patients were used as person-absent audiovisual teaching aids from which students learnt to make a case for physiotherapy intervention. The paper challenges physiotherapists and other professions using work-placement education to look behind the rhetoric of their placement documentation and explore the reality of students' learning in the field. The UK-based physiotherapy profession may wish to consider further the possible implications of its self-definition as a 'science-based healthcare profession' on its in

An RTT-Aware Virtual Machine Placement Method

Directory of Open Access Journals (Sweden)

Li Quan

2017-12-01

Full Text Available Virtualization is a key technology for mobile cloud computing (MCC and the virtual machine (VM is a core component of virtualization. VM provides a relatively independent running environment for different applications. Therefore, the VM placement problem focuses on how to place VMs on optimal physical machines, which ensures efficient use of resources and the quality of service, etc. Most previous work focuses on energy consumption, network traffic between VMs and so on and rarely consider the delay for end users’ requests. In contrast, the latency between requests and VMs is considered in this paper for the scenario of optimal VM placement in MCC. In order to minimize average RTT for all requests, the round-trip time (RTT is first used as the metric for the latency of requests. Based on our proposed RTT metric, an RTT-Aware VM placement algorithm is then proposed to minimize the average RTT. Furthermore, the case in which one of the core switches does not work is considered. A VM rescheduling algorithm is proposed to keep the average RTT lower and reduce the fluctuation of the average RTT. Finally, in the simulation study, our algorithm shows its advantage over existing methods, including random placement, the traffic-aware VM placement algorithm and the remaining utilization-aware algorithm.

Gaining experience in clinical mental health settings is central to the education of health practitioners. To facilitate the ongoing development of knowledge and practice in this area, we performed a review of the literature on clinical placements in mental health settings. Searches in Academic Search Complete, CINAHL, Medline and PsycINFO databases returned 244 records, of which 36 met the selection criteria for this review. Five additional papers were obtained through scanning the reference lists of those papers included from the initial search. The evidence suggests that clinical placements may have multiple benefits (e.g. improving students' skills, knowledge, attitudes towards people with mental health issues and confidence, as well as reducing their fears and anxieties about working in mental health). The location and structure of placements may affect outcomes, with mental health placements in non-mental health settings appearing to have minimal impact on key outcomes. The availability of clinical placements in mental health settings varies considerably among education providers, with some students completing their training without undertaking such structured clinical experiences. Students have generally reported that their placements in mental health settings have been positive and valuable experiences, but have raised concerns about the amount of support they received from education providers and healthcare staff. Several strategies have been shown to enhance clinical placement experiences (e.g. providing students with adequate preparation in the classroom, implementing learning contracts and providing clinical supervision). Educators and healthcare staff need to work together for the betterment of student learning and the healthcare professions.

Verification of proper placement of an intravenous catheter may not always be simple. We evaluated the auscultation technique for this purpose. Twenty healthy volunteers were randomized for 18G catheter inserted intravenously either in the right (12) or left arm (8), and subcutaneously in the opposite arm. A standard stethoscope was placed over an area approximately 3 cm proximal to the tip of the catheter in the presumed direction of the vein to grade on a 0-6 scale the murmur heard by rapidly injecting 2 mL of NaCl 0.9% solution. The auscultation was evaluated by a blinded staff anesthesiologist. All 20 intravenous injection were evaluated as flow murmurs, and were graded an average 5.65 (±0.98), whereas all 20 subcutaneous injections were evaluated as either crackles or no sound, and were graded an average 2.00 (±1.38), without negative results. Sensitivity was calculated as 95%. Specificity and Kappa could not be calculated due to an empty false-positive group. Being simple, handy and noninvasive, we recommend to use the auscultation technique for verification of the proper placement of an intravenous catheter when uncertain of its position. Data obtained in our limited sample of healthy subjects need to be confirmed in the clinical setting.

Geometric leaf placement strategies

Fenwick, J D; Temple, S W P; Clements, R W; Lawrence, G P; Mayles, H M O; Mayles, W P M

2004-01-01

Geometric leaf placement strategies for multileaf collimators (MLCs) typically involve the expansion of the beam's-eye-view contour of a target by a uniform MLC margin, followed by movement of the leaves until some point on each leaf end touches the expanded contour. Film-based dose-distribution measurements have been made to determine appropriate MLC margins-characterized through an index d 90 -for multileaves set using one particular strategy to straight lines lying at various angles to the direction of leaf travel. Simple trigonometric relationships exist between different geometric leaf placement strategies and are used to generalize the results of the film work into d 90 values for several different strategies. Measured d 90 values vary both with angle and leaf placement strategy. A model has been derived that explains and describes quite well the observed variations of d 90 with angle. The d 90 angular variations of the strategies studied differ substantially, and geometric and dosimetric reasoning suggests that the best strategy is the one with the least angular variation. Using this criterion, the best straightforwardly implementable strategy studied is a 'touch circle' approach for which semicircles are imagined to be inscribed within leaf ends, the leaves being moved until the semicircles just touch the expanded target outline

2014-03-01

To explore demographic differences in awarded marks of the final clinical placement in a physiotherapy undergraduate programme. Retrospective analysis of clinical placement assessment marks. A London university offering clinical placements throughout South East England. 333 physiotherapy students entering physiotherapy training between 2005 to 2009. Marks awarded following assessment using a clinical placement assessment form. The mean mark (SD) for age were standard entry 71 (7.4) vs. mature entry 72 (7.99) (ns); for gender male 72 (8.45) vs. female 71 (7.21) (ns); and ethnicity White British 72 (7.71) vs. ethnic minority 70 (7.01) (p=0.023). No interaction effects were observed between the independent variables and only ethnicity demonstrated a statistically significant effect (mean difference (MD) 2.4% 95%CI 0.5 to 4.3, F=5.24, p=0.023). This difference was maintained in most subcategories. Significant differences were observed for the interpersonal section (MD 2.21% 95%CI 0.14 to 4.28, F=4.409, p=0.03), the clinical reasoning section (MD 2.39% 95%CI 0.53 to 4.25, F=6.37, p=0.012) and the treatment section (MD 2.93 95%CI 1.10 to 4.83, F=9.198, p=0.003). Physiotherapy students from minority ethnic backgrounds were awarded a significantly lower mark than their white majority peers in final clinical placements, although the difference was small. Potential reasons are considered, with the strongest recommendation being for further enquiry into the potential relationship between ethnicity and success in undergraduate physiotherapy education.

2008-05-15

Purpose: To assess undergraduate radiography student perception of clinical placements and to evaluate their clinical learning experiences. Methods: To evaluate student perception of clinical placements, a Likert-scale questionnaire was used to assess clinical practice, the practice-learning environment. One hundred and seventy-eight undergraduate [student] radiographers participated in the study. Results: The students indicated they had adequate and enjoyed their time on the clinical placement. They also indicated the qualified staff was supportive, friendly and approachable. The students were able to achieve their learning outcomes during the placement. However placement venues, according to the students, had inadequate learning resources. No radiographic/medical imaging research findings, whether locally generated or otherwise, were used in clinical practice. Conclusions: Clinical placements had adequate student support. It provided a pleasant learning experience for the students and it enhanced their skills. Staff was willing and available to assist learning. Nevertheless, the training institutions, professional body and clinical placement providers need to make an effort to address inadequate learning resources (e.g. IT, library, study rooms) as well as the non-utilization of radiographic/medical imaging research findings.

Introduction: Radiation therapy students at Queensland University of Technology (QUT) attend clinical placements at five different clinical departments with varying resources and support strategies. This study aimed to determine the relative availability and perceived importance of different factors affecting student support while on clinical placement. The purpose of the research was to inform development of future support mechanisms to enhance radiation therapy students’ experience on clinical placement. Methods: This study used anonymous Likert-style surveys to gather data from years 1 and 2 radiation therapy students from QUT and clinical educators from Queensland relating to availability and importance of support mechanisms during clinical placements in a semester. Results: The study findings demonstrated student satisfaction with clinical support and suggested that level of support on placement influenced student employment choices. Staff support was perceived as more important than physical resources; particularly access to a named mentor, a clinical educator and weekly formative feedback. Both students and educators highlighted the impact of time pressures. Conclusions: The support offered to radiation therapy students by clinical staff is more highly valued than physical resources or models of placement support. Protected time and acknowledgement of the importance of clinical education roles are both invaluable. Joint investment in mentor support by both universities and clinical departments is crucial for facilitation of effective clinical learning. PMID:26229635

Use of the frontal process of the maxillary bone for implant placement to retain a nasal prosthesis: a clinical report.

Science.gov (United States)

Proussaefs, Periklis

2004-01-01

Implant placement to provide support and retention for nasal prostheses has been described in the literature. The anatomic sites that have been utilized for implant placement are the nasal bones, the premaxillary area through the nasal fossae, and the anterior wall of the frontal sinus. In the patient described, after a presurgical computerized tomography scan to determine adequacy of bone volume, 1 conventional threaded hydroxyapatite-coated root-form implant, created for intraoral use, was placed in the frontal process of the maxillary bone and 2 additional conventional implants were placed in the premaxillary area through the nasal fossa. Six months after implant placement, second-stage surgery was completed. A single bar connecting the 3 implants was fabricated. The removable nasal prosthesis was retained on the bar with 2 clips. An examination 1 year postsurgery revealed no clinical signs of pathosis. Long-term clinical follow-up of this case should continue and a sufficient number of additional cases should be investigated before use of the frontal process of the maxillary bone for implant retention can be recommended on a routine basis.

2013-10-01

Out-of-home placement decision-making in child welfare is founded on the best interest of the child in the least restrictive setting. After a child is removed from home, however, little is known about the mechanism of placement decision-making. This study aims to systematically examine the patterns of out-of-home placement decisions made in a state's child welfare system by comparing two models of placement decision-making: a multidisciplinary team decision-making model and a clinically based decision support algorithm. Based on records of 7816 placement decisions representing 6096 children over a 4-year period, hierarchical log-linear modeling characterized concordance or agreement, and discordance or disagreement when comparing the two models and accounting for age-appropriate placement options. Children aged below 16 had an overall concordance rate of 55.7%, most apparent in the least restrictive (20.4%) and the most restrictive placement (18.4%). Older youth showed greater discordant distributions (62.9%). Log-linear analysis confirmed the overall robustness of concordance (odd ratios [ORs] range: 2.9-442.0), though discordance was most evident from small deviations from the decision support algorithm, such as one-level under-placement in group home (OR=5.3) and one-level over-placement in residential treatment center (OR=4.8). Concordance should be further explored using child-level clinical and placement stability outcomes. Discordance might be explained by dynamic factors such as availability of placements, caregiver preferences, or policy changes and could be justified by positive child-level outcomes. Empirical placement decision-making is critical to a child's journey in child welfare and should be continuously improved to effect positive child welfare outcomes. Copyright © 2013 Elsevier Ltd.

Juvenile reentry and aftercare interventions: is mentoring a promising direction?

Science.gov (United States)

Abrams, Laura S; Mizel, Matthew L; Nguyen, Viet; Shlonsky, Aron

2014-01-01

This study uses systematic review methods to investigate the use of mentoring programs to assist young people in successfully transitioning back into their communities following a juvenile correctional placement. Few studies were found that used comparison or control groups and measured recidivism outcomes. The results of the studies were mixed, with one study finding no differences between groups, and the other two studies finding some recidivism reductions among youth who received the intervention. However, the absence of detailed information on the interventions, weak research designs, and the diversity of the mentoring programs contributed to an overall dearth of knowledge about the effectiveness of these interventions in reducing recidivism.

Laryngeal mask placement in a teaching institution: analysis of difficult placements [version 1; referees: 2 approved, 1 approved with reservations

Directory of Open Access Journals (Sweden)

Anastasia D Katsiampoura

2015-04-01

Full Text Available Background: Laryngeal mask airway (LMA placement is now considered a common airway management practice. Although there are many studies which focus on various airway techniques, research regarding difficult LMA placement is limited, particularly for anesthesiologist trainees. In our retrospective analysis we tried to identify predictive factors of difficult LMA placement in an academic training program. Methods: This retrospective analysis was derived from a research airway database, where data were collected prospectively at the Memorial Hermann Hospital, Texas Medical Center, Houston, TX, USA, from 2008 to 2010. All non-obstetric adult patients presenting for elective surgery requiring general anesthesia, were enrolled in this study: anesthesiology residents primarily managed the airways. The level of difficulty, number of attempts, and type of the extraglottic device placement were retrieved. Results: Sixty-nine unique Laryngeal Mask Airways (uLMAs were utilized as a primary airway device. Two independent predictors for difficult LMA placement were identified: gender and neck circumference. The sensitivity for one factor is 87.5% with a specificity of 50%. However with two risk factors, the specificity increases to the level of 93% and the sensitivity is 63%. Conclusion: In a large academic training program, besides uLMA not been used routinely, two risk factors for LMA difficulty were identified, female gender and large neck circumference. Neck circumference is increasingly being recognized as a significant predictor across the spectrum of airway management difficulties while female gender has not been previously reported as a risk factor for difficult LMA placement.

Is there a need for placement evaluations for specialist practice students? A proposal.

Science.gov (United States)

Sturge, Sally Anne

2014-10-01

This paper outlines a recent proposal justifying the initiation of standardised placement evaluations across specialist community public health nursing and specialist community nursing students while they undertake their educational programme. Within one approved education institute (AEI) it was identified that there was no standardised tool currently being used across the West Midlands, making the process of quality assurance extremely difficult. A clear rationale is provided for the use of such a tool, including supporting evidence from professional, statutory and regulatory bodies, health and education policies and quality assurance agencies. Placement evaluations are critical to students' learning, ensuring a safe and conducive environment, while providing a continuous cyclical process in conjunction with educational audits to allow the opportunity of regular assessment of the learning environment conforming to the Nursing Midwifery Council's risk-based approach. In light of the recent recommendations from the Francis report, it is pivotal that organisations such as the NHS and AEIs engage proactively together, fostering an open and transparent relationship to ensure standards of care are of the highest quality. Aspects of leadership theory are also discussed to enable the planned change to be successful.

The Effect of Product Placement Marketing on Effectiveness of Internet Advertising

Science.gov (United States)

Liao, Hsiu-Li; Liu, Su-Houn; Pi, Shih-Ming; Chen, Hui-Ju

Compared to the traditional way of doing advertising, such as ad Banners, internet product placement is now emerging as a promising strategy for advertisers to do their job effectively in this Web 2.0 era. Therefore, this study focuses on the effectiveness of product placement advertising on the Internet. The results show that product prominence (Subtle or Prominent) and presentation of the advertising (Video or Images) significantly impacts the effectiveness of product placement advertising on the Internet, including brand impression, advertising attitude, and intention to click. Product prominence and presentation of the advertisement have an interactive impact. Our findings indicated that presenting the product through videos will enhance higher levels of advertising attitude, brand impression, and intention to click than presenting it through still images. Subtle placements will increase the level of advertising attitude and intention to click more so than prominent placements. But prominent placements increase the brand impression more than the subtle placements.

2017-02-01

As heavy media users, adolescents are frequently exposed to embedded advertising formats such as brand placements. Because this may lead to unwitting persuasion, regulations prescribe disclosure of brand placements. This study aimed to increase our understanding of the effects of disclosing television brand placements and disclosure duration on adolescents' persuasion knowledge (i.e., recognition of brand placement as being advertising, understanding that brand placement has a persuasive intent and critical attitude toward brand placement) and brand responses (i.e., brand memory and brand attitude). To do so, an earlier study that was conducted among adults was replicated among adolescents aged 13-17 years (N = 221, 44 % female). The present study shows that brand placement disclosure had limited effects on adolescents' persuasion knowledge as it only affected adolescents' understanding of persuasive intent, did not mitigate persuasion, but did increase brand memory. These findings suggest that brand placement disclosure has fundamentally different effects on adolescents than on adults: the disclosures had less effects on activating persuasion knowledge and mitigating persuasion among adolescents than among adults. Implications for advertising disclosure regulation and consequences for advertisers are discussed.

ESL Placement and Schools: Effects on Immigrant Achievement.

Science.gov (United States)

Callahan, Rebecca; Wilkinson, Lindsey; Muller, Chandra; Frisco, Michelle

2009-05-01

In this study, the authors explore English as a Second Language (ESL) placement as a measure of how schools label and process immigrant students. Using propensity score matching and data from the Adolescent Health and Academic Achievement Study and the National Longitudinal Study of Adolescent Health, the authors estimate the effect of ESL placement on immigrant achievement. In schools with more immigrant students, the authors find that ESL placement results in higher levels of academic performance; in schools with few immigrant students, the effect reverses. This is not to suggest a one-size-fits-all policy; many immigrant students, regardless of school composition, generational status, or ESL placement, struggle to achieve at levels sufficient for acceptance to a 4-year university. This study offers several factors to be taken into consideration as schools develop policies and practices to provide immigrant students opportunities to learn.

Rotation placements help students' understanding of intensive care.

Science.gov (United States)

Abbott, Lisa

2011-07-01

It is vital that children's nursing students are fit for practice when they qualify and are able to meet various essential skills as defined by the Nursing and Midwifery Council (NMC). To gain the knowledge and skills required, students need placements in areas where high dependency and potentially intensive care are delivered. Efforts to maximise the number of students experiencing intensive care as a placement have led to the development of the paediatric intensive care unit (PICU) rotation, increasing placements on the PICU from 5 to 40 per cent of the student cohort per year. The lecturer practitioner organises the rotation, providing credible links between university and practice areas, while supporting students and staff in offering a high-quality placement experience. Students say the rotation offers a positive insight into PICU nursing, helping them develop knowledge and skills in a technical area and creating an interest in this specialty.

Impact of Anticoagulation in Elderly Patients With Pulmonary Embolism That Undergo IVC Filter Placement: A Retrospective Cohort Study.

Science.gov (United States)

Falatko, John M; Dalal, Bhavinkumar; Qu, Lihua

2017-12-01

Anticoagulation is the primary treatment for pulmonary embolism (PE). Inferior vena cava (IVC) filters are an adjunctive intervention to prevent recurrent pulmonary embolism. Long-term outcomes in elderly patients with contraindications to anticoagulation after IVC filter placement for prevention of recurrent pulmonary embolism have yet to be assessed. Patients ≥60years of age, that had an IVC filter placed between 1 January, 2008 and 2 February, 2013, with a primary diagnosis of pulmonary embolism, were included. Patients that died during index hospitalisation, were discharged to hospice, or had active malignancy were excluded. The primary endpoint was overall survival. Patients were divided depending on whether they were treated with an approved anticoagulant for VTE or had no anticoagulant. Of the 152 patients identified, 55 were not anti-coagulated after IVC filter placement. The incidence of death was 0.4 per 1000 filter days and 0.7 per 1000 filter days in the anti-coagulated and untreated groups respectively (p-value=0.06). After statistical correction for co-morbid conditions, the effect of anticoagulation was not significant (HR 0.82 CI 0.49-1.37, p-value 0.46). Age was a significant confounder that was associated with death. Increased BMI was protective. Indications for IVC filter placement were numerous, but similar between the two groups. Treatment with an approved anticoagulant is recommended after IVC filter placement for prevention of recurrent PE, however its effect may be attenuated by advanced age. In elderly patients that have undergone IVC filter placement for prevention of recurrent PE, survival may be more dependent on age and co-morbid conditions than exposure to anticoagulation.

This analytical framework determines the available distance for motorists to read and react to CMS messages based on CMS character height, driver's cone of vision, CMS pixel's cone of legibility, roadway horizontal curve radius, and CMS lateral and vertical placement. Sample design charts were developed to illustrate how the analytical framework may facilitate CMS placement design.

FtsZ placement in nucleoid-free bacteria.

Directory of Open Access Journals (Sweden)

Manuel Pazos

Full Text Available We describe the placement of the cytoplasmic FtsZ protein, an essential component of the division septum, in nucleoid-free Escherichia coli maxicells. The absence of the nucleoid is accompanied in maxicells by degradation of the SlmA protein. This protein, together with the nucleoid, prevents the placement of the septum in the regions occupied by the chromosome by a mechanism called nucleoid occlusion (NO. A second septum placement mechanism, the MinCDE system (Min involving a pole-to-pole oscillation of three proteins, nonetheless remains active in maxicells. Both Min and NO act on the polymerization of FtsZ, preventing its assembly into an FtsZ-ring except at midcell. Our results show that even in the total absence of NO, Min oscillations can direct placement of FtsZ in maxicells. Deletion of the FtsZ carboxyl terminal domain (FtsZ*, a central hub that receives signals from a variety of proteins including MinC, FtsA and ZipA, produces a Min-insensitive form of FtsZ unable to interact with the membrane-anchoring FtsA and ZipA proteins. This protein produces a totally disorganized pattern of FtsZ localization inside the maxicell cytoplasm. In contrast, FtsZ*-VM, an artificially cytoplasmic membrane-anchored variant of FtsZ*, forms helical or repetitive ring structures distributed along the entire length of maxicells even in the absence of NO. These results show that membrane anchoring is needed to organize FtsZ into rings and underscore the role of the C-terminal hub of FtsZ for their correct placement.

We describe the placement of the cytoplasmic FtsZ protein, an essential component of the division septum, in nucleoid-free Escherichia coli maxicells. The absence of the nucleoid is accompanied in maxicells by degradation of the SlmA protein. This protein, together with the nucleoid, prevents the placement of the septum in the regions occupied by the chromosome by a mechanism called nucleoid occlusion (NO). A second septum placement mechanism, the MinCDE system (Min) involving a pole-to-pole oscillation of three proteins, nonetheless remains active in maxicells. Both Min and NO act on the polymerization of FtsZ, preventing its assembly into an FtsZ-ring except at midcell. Our results show that even in the total absence of NO, Min oscillations can direct placement of FtsZ in maxicells. Deletion of the FtsZ carboxyl terminal domain (FtsZ*), a central hub that receives signals from a variety of proteins including MinC, FtsA and ZipA, produces a Min-insensitive form of FtsZ unable to interact with the membrane-anchoring FtsA and ZipA proteins.

Do position and size matter? An analysis of cage and placement variables for optimum lordosis in PLIF reconstruction.

Science.gov (United States)

Landham, Priyan R; Don, Angus S; Robertson, Peter A

2017-11-01

To examine monosegmental lordosis after posterior lumbar interbody fusion (PLIF) surgery and relate lordosis to cage size, shape, and placement. Eighty-three consecutive patients underwent single-level PLIF with paired identical lordotic cages involving a wide decompression and bilateral facetectomies. Cage parameters relating to size (height, lordosis, and length) and placement (expressed as a ratio relative to the length of the inferior vertebral endplate) were recorded. Centre point ratio (CPR) was the distance to the centre of both cages and indicated mean position of both cages. Posterior gap ratio (PGR) was the distance to the most posterior cage and indicated position and cage length indirectly. Relationships between lordosis and cage parameters were explored. Mean lordosis increased by 5.98° (SD 6.86°). The cages used varied in length from 20 to 27 mm, in lordosis from 10° to 18°, and in anterior cage height from 10 to 17 mm. The mean cage placement as determined by CPR was 0.54 and by PGR was 0.16. The significant correlations were: both CPR and PGR with lordosis gain at surgery (r = 0.597 and 0.537, respectively, p lordosis with the final lordosis (r = 0.234, p lordosis (r = -0.297, p lordosis during PLIF surgery. Anterior placement with sufficient "clear space" behind the cages is recommended. In addition, cages should be of moderate height and length, so that they act as an effective pivot for lordosis.

Peripherally inserted central catheter (PICC) is among the most common procedures performed in children in the hospital setting. PICC insertion can be simplified with the use of a sheathed needle as an alternative to the modified Seldinger technique. To retrospectively evaluate PICC placement for the technique used and the incidence of complications at a large pediatric tertiary care center. We retrospectively reviewed all PICC placements at a single institution over a 4-year period. We reviewed patient records for demographic data, PICC placement technique, catheter size and number of lumens, and the incidence of complications (i.e. multiple attempted puncture sites, phlebitis and vessel thrombosis). We analyzed complication rates between two placement techniques using a chi-square test. We identified 8,816 successful PICC placements, 4,749 (53.9%) in males and 4,067 (46.1%) in females. The average age of the patients for which a line was placed was 5.6 years (range 1 day to 45 years). A direct sheathed needle puncture technique was used in 8,362 (94.9%) placements and a modified Seldinger technique was used in 454 (5.1%). Complications occurred in 312 (3.7%) of direct sheathed needle puncture placements versus 17 (3.7%) of modified Seldinger placements (P = 0.99). Multiple puncture sites were required in 175 (2.1%) attempted direct sheathed needle puncture placements compared with 8 (1.7%) attempted modified Seldinger placements (P = 0.63). Phlebitis occurred in 94 (1.1%) direct sheathed needle puncture lines versus 5 (1.1%) modified Seldinger placed lines (P = 0.96). Vessel thrombosis occurred in 43 (0.5%) direct sheathed needle puncture lines versus 4 (0.9%) modified Seldinger placed lines (P = 0.30). The direct peel-away sheathed needle vessel puncture technique and the modified Seldinger technique used to place PICC lines in children have similar complication rates. (orig.)

Distributed generator (DG) resources are small, self-contained electric generating plants that can provide power to homes, businesses or industrial facilities in distribution feeders. They can be used to reduce power loss and improve service reliability. However, the values of DGs are largely dependent on their types, sizes and locations as they were installed in distribution feeders. A value-based method is proposed in this paper to enhance the reliability and obtain the benefits for DG placement. The benefits of DG placement described in this paper include power cost saving, power loss reduction, and reliability enhancement. The costs of DG placement include the investment, maintenance and operating costs. The proposed value-based method tries to find the best tradeoff between the costs and benefits of DG placement and then find the optimal types of DG and their corresponding locations and sizes in distribution feeders. The derived formulations are solved by a genetic algorithm based method. Test results show that with proper types, sizes and installation site selection, DG placement can be used to improve system reliability, reduce customer interruption costs and save power cost; as well as enabling electric utilities to obtain the maximal economical benefits.

1998-01-01

DOE Order 420.1, ''Facility Safety'', requires that facilities or sites with hazardous materials be provided with instrumentation or other means to detect and record the occurrences and severity of seismic events. These requirements assure that necessary records are available after an earthquake for evaluation purposes and to supplement other data to justify a facility restart or curtailing plant operations after an earthquake. This report documents the basis for the selection of Savannah River Site areas and existing facilities to be instrumented. The need to install instrumentation in new facilities such as the Actinide Packaging and Storage Facility, Commercial Light Water Reactor Tritium Extraction Facility and the Accelerator Production of Tritium Facility will be assessed separately

Life cycle assessment for dredged sediment placement strategies.

Dredging to maintain navigable waterways is important for supporting trade and economic sustainability. Dredged sediments are removed from the waterways and then must be managed in a way that meets regulatory standards and properly balances management costs and risks. Selection of a best management alternative often results in stakeholder conflict regarding tradeoffs between local environmental impacts associated with less expensive alternatives (e.g., open water placement), more expensive measures that require sediment disposal in constructed facilities far away (e.g., landfills), or beneficial uses that may be perceived as risky (e.g., beach nourishment or island creation). Current sediment-placement decisions often focus on local and immediate environmental effects from the sediment itself, ignoring a variety of distributed and long-term effects from transportation and placement activities. These extended effects have implications for climate change, resource consumption, and environmental and human health, which may be meaningful topics for many stakeholders not currently considered. Life-Cycle Assessment (LCA) provides a systematic and quantitative method for accounting for this wider range of impacts and benefits across all sediment management project stages and time horizons. This paper applies a cradle-to-use LCA to dredged-sediment placement through a comparative analysis of potential upland, open water, and containment-island placement alternatives in the Long Island Sound region of NY/CT. Results suggest that, in cases dealing with uncontaminated sediments, upland placement may be the most environmentally burdensome alternative, per ton-kilometer of placed material, due to the emissions associated with diesel fuel combustion and electricity production and consumption required for the extra handling and transportation. These results can be traded-off with the ecosystem impacts of the sediments themselves in a decision-making framework. Published by

Workplace learning (WPL) placements are a mandatory part of occupational therapy courses. There is some evidence that suggests WPL placements in international settings are beneficial for students' learning, and personal and professional development. The aim of this study was to explore the impact an international WPL placement in Vietnam had on the perceived personal and professional development of a group of Australian occupational therapy graduates. Interpretative phenomenological analysis was used to explore the perceptions of how participation in the Charles Sturt University School of Community Health's Vietnam placement influenced the personal and professional development of occupational therapy graduates. Individual semi-structured interviews were conducted with nine graduates who participated in the Vietnam placement when they were final year occupational therapy students. Interviews were audio-recorded, transcribed verbatim and individually analysed to identify key themes. Two major themes emerged from the analysis: becoming resourceful, resilient and confident, and becoming respectful of difference. The participants indicated that participation in the Vietnam placement had a positive impact on their personal and professional development. Participants indicated that the Vietnam placement enabled them to develop their resourcefulness, resilience, reasoning skills, cultural competence, confidence and independence, beyond what they felt would have achieved on a domestic placement. For these reason these participants found the placement a beneficial and worthwhile experience. © 2016 Occupational Therapy Australia.

Heterocyst placement strategies to maximize the growth of cyanobacterial filaments

International Nuclear Information System (INIS)

Brown, Aidan I; Rutenberg, Andrew D

2012-01-01

Under conditions of limited fixed-nitrogen, some filamentous cyanobacteria develop a regular pattern of heterocyst cells that fix nitrogen for the remaining vegetative cells. We examine three different heterocyst placement strategies by quantitatively modelling filament growth while varying both external fixed-nitrogen and leakage from the filament. We find that there is an optimum heterocyst frequency which maximizes the growth rate of the filament; the optimum frequency decreases as the external fixed-nitrogen concentration increases but increases as the leakage increases. In the presence of leakage, filaments implementing a local heterocyst placement strategy grow significantly faster than filaments implementing random heterocyst placement strategies. With no extracellular fixed-nitrogen, consistent with recent experimental studies of Anabaena sp. PCC 7120, the modelled heterocyst spacing distribution using our local heterocyst placement strategy is qualitatively similar to experimentally observed patterns. As external fixed-nitrogen is increased, the spacing distribution for our local placement strategy retains the same shape, while the average spacing between heterocysts continuously increases.

Objective: To evaluate the feasibility and effectiveness of duodenal feeding tube placement under fluoroscopic guidance and its clinical application. Methods: The transnasal duodenal nutriment tubes placement under fluoroscopic guidance were performed in 59 patients from June 3th, 2003 to August 17th, 2007. The successful placement of the feeding tube was defined as that of the tube tip was fixed at or distal to the duodenojejunal junction. Results: 57 out of 59 patients were successfully managed by feeding tube placement, with primary successful rate of 96.6% (57/59). The remaining two failures were due to overdistention of the stomach and were further managed after gastrointestinal decompression thoroughly. The mean fluoroscopy time of the procedure was 17.8 minutes with no severe immediate or delayed complications. Conclusion: The transnasal duodenal nutrient feeding tube placement under fluoroscopic guidance is a safe,economic, and effective management for enteral nutrition, providing extensive clinical utilization.

Optimal PMU Placement with Uncertainty Using Pareto Method

Directory of Open Access Journals (Sweden)

A. Ketabi

2012-01-01

Full Text Available This paper proposes a method for optimal placement of Phasor Measurement Units (PMUs in state estimation considering uncertainty. State estimation has first been turned into an optimization exercise in which the objective function is selected to be the number of unobservable buses which is determined based on Singular Value Decomposition (SVD. For the normal condition, Differential Evolution (DE algorithm is used to find the optimal placement of PMUs. By considering uncertainty, a multiobjective optimization exercise is hence formulated. To achieve this, DE algorithm based on Pareto optimum method has been proposed here. The suggested strategy is applied on the IEEE 30-bus test system in several case studies to evaluate the optimal PMUs placement.

Good, S.; Asch, M.R.; Jaffer, N.; Casson, A.G.

1997-01-01

To assess the usefulness of covered, self expanding metallic stents for alleviating stricture associated with malignant esophageal lesions. Patients and methods: Self-expanding metallic stents were placed in 10 patients with dysphagia related to stricture caused by malignant esophageal lesions. The stents were placed fluoroscopically with local anesthesia, and patency of the esophageal lumen was assessed by barium study after the procedure. The patients were then followed clinically. Results: In all 10 cases patency of the lumen was renewed after stent placement. After the procedure 9 of the patients could tolerate a normal or near-normal diet; in the other patient esophageal perforation occurred, and clinical deterioration prevented oral intake of food. In one patient, 2 stents were needed because of the length of the stricture. Two patients experienced reflux after placement of the stent across the gastro-esophageal junction. Another patient had asymptomatic aspiration after stent placement in the proximal esophagus. In 2 patients, symptoms associated with tracheoesophageal fistula were relieved after placement of the stents. Six of the 10 patients died; mean survival after the procedure was 12 (range 1 to 56) weeks. The other 4 patients were alive at the time of writing, having survived for a mean of 7.5 (range 2 to 13) weeks; all of these patients tolerated a near-normal diet. Conclusions: The placement of covered, self-expanding metallic stents is a quick, effective method of palliating dysphagia related to stricture caused by malignant esophageal lesions. (author)

Hollow mandrin facilitates external ventricular drainage placement.

Science.gov (United States)

Heese, O; Regelsberger, J; Kehler, U; Westphal, M

2005-07-01

Placement of ventricular catheters is a routine procedure in neurosurgery. Ventricle puncture is done using a flexible ventricular catheter stabilised by a solid steel mandrin in order to improve stability during brain penetration. A correct catheter placement is confirmed after removing the solid steel mandrin by observation of cerebrospinal fluid (CSF) flow out of the flexible catheter. Incorrect placement makes further punctures necessary. The newly developed device allows CSF flow observation during the puncture procedure and in addition precise intracranial pressure (ICP) measurement. The developed mandrin is hollow with a blunt tip. On one side 4-5 small holes with a diameter of 0.8 mm are drilled corresponding exactly with the holes in the ventricular catheter, allowing CSF to pass into the hollow mandrin as soon as the ventricle is reached. By connecting a small translucent tube at the distal portion of the hollow mandrin ICP can be measured without loss of CSF. The system has been used in 15 patients with subarachnoid haemorrhage (SAH) or intraventricular haemeorrhage (IVH) and subsequent hydrocephalus. The new system improved the external ventricular drainage implantation procedure. In all 15 patients catheter placement was correct. ICP measurement was easy to perform immediately at ventricle puncture. In 4 patients at puncture no spontaneous CSF flow was observed, therefore by connecting a syringe and gentle aspiration of CSF correct placement was confirmed in this unexpected low pressure hydrocephalus. Otherwise by using the conventional technique further punctures would have been necessary. Advantages of the new technique are less puncture procedures with a lower risk of damage to neural structures and reduced risk of intracranial haemorrhages. Implantation of the ventricular catheter to far into the brain can be monitored and this complication can be overcome. Using the connected pressure monitoring tube an exact measurement of the opening

A Cloud-Computing-Based Data Placement Strategy in High-Speed Railway

Directory of Open Access Journals (Sweden)

Hanning Wang

2012-01-01

Full Text Available As an important component of China’s transportation data sharing system, high-speed railway data sharing is a typical application of data-intensive computing. Currently, most high-speed railway data is shared in cloud computing environment. Thus, there is an urgent need for an effective cloud-computing-based data placement strategy in high-speed railway. In this paper, a new data placement strategy named hierarchical structure data placement strategy is proposed. The proposed method combines the semidefinite programming algorithm with the dynamic interval mapping algorithm. The semi-definite programming algorithm is suitable for the placement of files with various replications, ensuring that different replications of a file are placed on different storage devices, while the dynamic interval mapping algorithm ensures better self-adaptability of the data storage system. A hierarchical data placement strategy is proposed for large-scale networks. In this paper, a new theoretical analysis is provided, which is put in comparison with several other previous data placement approaches, showing the efficacy of the new analysis in several experiments.

FPGA Congestion-Driven Placement Refinement

Energy Technology Data Exchange (ETDEWEB)

Vicente de, J.

2005-07-01

The routing congestion usually limits the complete proficiency of the FPGA logic resources. A key question can be formulated regarding the benefits of estimating the congestion at placement stage. In the last years, it is gaining acceptance the idea of a detailed placement taking into account congestion. In this paper, we resort to the Thermodynamic Simulated Annealing (TSA) algorithm to perform a congestion-driven placement refinement on the top of the common Bounding-Box pre optimized solution. The adaptive properties of TSA allow the search to preserve the solution quality of the pre optimized solution while improving other fine-grain objectives. Regarding the cost function two approaches have been considered. In the first one Expected Occupation (EO), a detailed probabilistic model to account for channel congestion is evaluated. We show that in spite of the minute detail of EO, the inherent uncertainty of this probabilistic model impedes to relieve congestion beyond the sole application of the Bounding-Box cost function. In the second approach we resort to the fast Rectilinear Steiner Regions algorithm to perform not an estimation but a measurement of the global routing congestion. This second strategy allows us to successfully reduce the requested channel width for a set of benchmark circuits with respect to the widespread Versatile Place and Route (VPR) tool.

To explore and empower physiotherapy students who reported being bullied or harassed on clinical placements by co-developing, implementing and evaluating strategies that could be adopted by the university. A participatory action research design was employed. Two focus groups were carried out involving 5 final year physiotherapy students. In the first focus group negative experiences were discussed and coping strategies suggested for their penultimate placement. A second focus group was held following the students' final placement when these strategies were evaluated and further ones proposed. A thematic analysis of the data was carried out. Four themes and sub-themes emerged from the analysis. The four themes were negative experiences on placement, coping strategies, the role of the visiting tutor and the assessment. The students' highlighted various degrees of threat to their efficacy and in most cases could draw upon a suggested 'tool box' of coping strategies. They all agreed that serious cases of harassment require wider support from the University senior management team which should be clearly documented. The role of the visiting tutor was deemed to be critical in these situations and recommendations were made regarding this role and the assessment of placements. Students understand that they are going to be assessed before achieving their professional qualification and in essence they will always find themselves in a hierarchical position but equally fairness must prevail and it is important and that there are clear avenues for them to seek support.

Plaice, Caroline; Lloyd, Jon; Shaw, Pauline

2017-03-01

The aim of this research was to explore the library and information needs of health and social care students whilst on placement. Both desk and primary research were conducted and included an online questionnaire to students and semi-structured interviews. The questionnaire was completed by 252 students from a variety of programmes, equivalent to a 10% response rate. The results indicate a wide range of factors impacting on the library and information experiences of students. Whilst differences in the availability of a physical library in hospital or community locations still exist, these are mitigated by technology and a preference for home study. A significant result is that 77% (n = 193) of students on placement study at home, using a variety of Internet-connected devices. This highlights a marked change in practice and underlines the need for mobile-compliant e-resources and accessible at-a-distance services. As a result of this research, practical recommendations on how library support can be improved were developed including enhanced collaboration and learning with NHS colleagues, and knowledge sharing with other departments within the University who support our students. © 2017 Health Libraries Group.

Recommendations to the NRC for soil cover systems over uranium mill tailings and low-level radioactive wastes

Bennett, R.D.; Kimbrell, A.F.

1991-02-01

The US Army Engineer Waterways Experiment Station (WES) has provided recommendations to the US Nuclear Regulatory Commission (NRC) for the selection placement, compaction, testing, and acceptance of soils proposed to be placed in cover systems over uranium mill tailings and low-level radioactive wastes. The recommendations from WES are contained in three volumes of NUREG/CR-5432. Volume 1 identifies the various soil types and engineering properties that are needed to fulfill important soil cover functions. The identified soils are then ranked according to their capability to perform the low-permeability and filter and drainage functions.

The aim of this paper is to describe the technique of percutaneous ultrasound (US)-guided placement of a peritoneal port-catheter in an interventional radiological setting. Nineteen patients with peritoneal carcinomatosis were selected for intraperitoneal port-catheter placement in order to perform intracavitary receptor-immuno- or radio-immunotherapy with Ytrium-90. All the procedures were performed percutaneously under US and fluoro guidance; the insertion site for catheters was chosen according to abdominal conditions and US findings: all devices were implanted at the lower abdominal quadrants. All patients were followed up with CT and US according to the therapy protocol. The procedure was successfully completed in 15/19 patients, in 4 being contraindicated by peritoneal adhesions. No procedure-related complications and device occlusions during therapy were observed; one catheter displaced 7 months later the placement. In our experience, this procedure was feasible, reliable and easy to perform, allowing the correct administration of the planned intracavitary therapy. Peritoneal adhesions are the main limitation of peritoneal port placement. (orig.)

A risk-based sensor placement methodology

International Nuclear Information System (INIS)

Lee, Ronald W.; Kulesz, James J.

2008-01-01

A risk-based sensor placement methodology is proposed to solve the problem of optimal location of sensors to protect population against the exposure to, and effects of, known and/or postulated chemical, biological, and/or radiological threats. Risk is calculated as a quantitative value representing population at risk from exposure at standard exposure levels. Historical meteorological data are used to characterize weather conditions as the frequency of wind speed and direction pairs. The meteorological data drive atmospheric transport and dispersion modeling of the threats, the results of which are used to calculate risk values. Sensor locations are determined via an iterative dynamic programming algorithm whereby threats detected by sensors placed in prior iterations are removed from consideration in subsequent iterations. In addition to the risk-based placement algorithm, the proposed methodology provides a quantification of the marginal utility of each additional sensor. This is the fraction of the total risk accounted for by placement of the sensor. Thus, the criteria for halting the iterative process can be the number of sensors available, a threshold marginal utility value, and/or a minimum cumulative utility achieved with all sensors

Occupational therapy educators are challenged to provide students with practical experiences which prepare them for ever changing health-care contexts on graduation. Role-emerging placements have been widely used internationally to help meet this challenge, but research into the learning experiences of students during these innovative placements is limited. This research investigated the enablers and barriers to learning from the perspectives of students on such placements from two European universities. Two separate qualitative studies tracked 10 final year students. Interviews explored their learning experiences prior to, during and after an eight- or 10-week role-emerging placement in a range of settings. Four themes emerged, which were (1) adapting to less doing, more thinking and planning; (2) understanding the complexity of collaboration and making it work; (3) emotional extremes; and (4) realising and using the occupational therapy perspective. These placements presented a 'roller coaster' of authentic learning experiences which created the opportunity for students to use occupation in practice and develop skills for collaborative working in an interprofessional environment. Whereas students viewed their role-emerging placement experiences positively, challenges included the emotional responses of students and placement pace. Findings suggest the need for supportive student placement experiences in both established and role-emerging areas to prepare students for a range of opportunities in an uncertain future. © 2013 Occupational Therapy Australia.

The History of Nontraditional or Ectopic Placement of Reservoirs in Prosthetic Urology.

2016-04-01

Reservoir placement during implantation of prosthetic urology devices has been problematic throughout the history of the surgical treatment of erectile dysfunction and urinary incontinence. We thought it would be interesting to review the history of reservoir placement leading up to current surgical techniques. To provide an overview of the past and present techniques for reservoir placement and discuss the evolutionary process leading to safe and effective placement of prosthetic reservoirs. We reviewed data pertaining to inflatable penile prosthesis (IPP) reservoirs and pressure-regulating balloons (PRB) in a chronological fashion, spanning 25 years. Main outcomes included a historical review of techniques for IPP reservoir and PRB placement leading to the subsequent incremental improvements in safety and efficacy when performing penile implants and artificial urinary sphincters. Prosthetic urologic reservoirs have traditionally been placed in the retropubic space. Over the years, urologists have attempted use of alternative spaces including peritoneal, epigastric, "ectopic," posterior to transversalis, and high submuscular. Current advances in prosthetic urologic reservoir placement allow safe and effective abdominal wall placement of reservoirs. These novel approaches appear to be so effective that urologists may now be able to cease using the traditional retropubic space for reservoir placement, even in the case of virgin pelves.

To describe incorrect positions of Essure microinserts detected at 3 months' follow-up. Case report. Outpatient department of obstetrics and gynecology in a Dutch teaching hospital. Initial series of 100 patients who underwent hysteroscopic sterilization using Essure between December 2003 and June 2004. Hysteroscopic placement of the Essure System, follow-up at 3 months with transvaginal ultrasound (TVU), and hysterosalpingography. Bilateral placement rate, tubal obstruction, and detection of incorrect Essure microinsert localization at follow-up after apparent successful bilateral placement. Bilateral placement of Essure microinserts in one session was successful in 93 women (93%). In 90 of these women (96.8%), tubal obstruction was proven at follow-up 3 months later. Three incorrect positions of an Essure insert were seen: two expulsions and one perforation into the abdominal cavity. Incorrect position of Essure microinserts was seen only when the initial placement procedure was difficult. When a placement procedure was difficult or other suboptimal conditions are present during the procedure, we advise performing a TVU or pelvic X-ray in these women 4 weeks after the procedure or after the first vaginal bleeding, instead of waiting for follow-up after 3 months.

Can we omit scintiscanning of the skeleton in follow-up aftercare of carcinoma of the breast?

International Nuclear Information System (INIS)

Schuenemann, H.

1989-01-01

630 women patients of the Bad Trissl clinic were admitted in 1987/88 to a prospective study to find out whether scintiscanning, or radionuclide imaging, of the skeleton can be omitted completely or in part in the after care and follow-up of carcinoma of the breast. The initial criterion was a postoperative carcinoma of the breast without metastasizing in the skeleton at the time the study began or the patient was admitted to the study. Careful pain anamnesis was performed by means of prepared questions, and a detailed clinical examination conducted to detect any pain in the skeleton of the patient concerned. This was followed by whole body scintiscanning of the skeleton and complementary X-ray films, if necessary additional examinations. It was found that clinical findings and imaging methods agreed in 545 patients. In 55 cases a finding that was clinically suspicious of metastases or doubtful, could be refuted by both scintiscan and by X-ray, osseous metastasizing would have been overlooked without skeleton scintiscan in 14 patients only (2.2%), 11 of these 14 patients were high-risk patients (negative hormonal receptor status, axillary lymph node metastases). Hence, it will be sufficient to employ scintiscanning in the aftercare and follow-up of carcinoma of the breast on a risk-adapted basis provided this is preceded by careful pain analysis and clinical examination. Failure to detect metastasizing in the skeleton will then occur in only 3 of 630 patients (0.48%). In this manner 40% of scintiscans can be omitted in future. (orig.) [de

Study on the placement of phosphorus fertilizer to improve fertilizer utilization by lowland rice

Sisworo, W.H.; Riswantoro; Mardjo, M.

1976-01-01

An experiment for studying the placement of phosphorus fertilizer was carried out in the glass house by using 32 P-labelled superphosphate. The specific activity of the labelled fertilizer used was 0,25 mCi/g P 2 O 5 . Three placement methods were studied: (1) Hill placement: Fertilizer was burried at a distance of 5cm from the plants at the depth of 5 cm, (2) Surface placement: Fertilizer was spread on the surface, and (3) Soil mixed application: Fertilizer was mixed with the soil at the depth of 5 cm. Superphosphate was applied at the rates of 0, 30, 60, 90, and 120 kg P 25 /ha. Results obtained from the experiment showed that the dry matter production was significantly affected by the methods of placement of phosphorus fertilizer. Soil mixed placement gave the lowest yield of dry plant material. It differed significantly from the two other methods of placement. However, there was no significant difference between hill and surface placement. The placement of phosphorus fertilizer significantly affected the total uptake of phosphorus nutrient, uptake fertilizer phosphorus, and the percentage of fertilizer utilization. Surface placement gave the highest utilization of fertilizer when supplied at rates higher than 60 kg P 2 O 5 /ha. At low rate applications, hill placement was the best, but, at rates higher than 60 kg P 2 O 5 /ha the percentage of fertilizer utilization decreased. Soil mixed application was the least efficient fertilizer utilization. (author)

2014-03-01

To identify risk factors for port infections within 30 days of placement. A retrospective chart review of port placements from 2002-2009 was conducted. Patients who had port removals secondary to infection within the first 30 days of placement were included. This group of patients was compared with a control group of patients with ports with no evidence of infection. For every one patient with a port infection, two control subjects were chosen of the same gender and new port placement during the same month as the corresponding patient with an infected port. From 2002-2009, 4,404 ports were placed. Of the 4,404 patients, 33 (0.7%) were found to have a port infection within 30 days of placement. Compared with the control group, the early infection group had a higher prevalence of leukopenia (21.2% vs 6.1%, P = .039) and thrombocytopenia (33% vs 12%, P = .0158). There was also a higher prevalence of an inpatient hospital stay during port placement and high international normalized ratio in the early infection group. Low preoperative white blood cell and platelet counts were risk factors for early infection. Abnormal coagulation profiles and inpatient access of ports after placement could be additional risk factors. Copyright © 2014 SIR. Published by Elsevier Inc. All rights reserved.

The clinical impact of posterior crown margin placement on gingival health has not been thoroughly quantified. This study evaluated the effect of posterior crown margin placement with multivariate analysis. Ten general dentists reviewed 240 patients with 480 metal-ceramic crowns in a prospective clinical trial. The alloy was randomly selected from 2 high gold, 1 low gold, and 1 palladium alloy. Variables were the alloy used, oral hygiene index score before treatment, location of crown margins at baseline, and plaque index and sulcus bleeding index scores recorded for restored and control teeth after 1 year. The effect of crown margin placement on sulcular bleeding and plaque accumulation was analyzed with regression models (Prisk of bleeding at intrasulcular posterior crown margins was approximately twice that at supragingival margins. Poor oral hygiene before treatment and plaque also were associated with sulcular bleeding. Facial sites exhibited a lower probability of sulcular bleeding than lingual surfaces. Type of alloy did not influence sulcular bleeding. In this study, placement of crown margins was one of several parameters that affected gingival health.

The purpose was to review our experiences and determine if applying the sky blue method is reliable in confirming gastric tube (GT) placement in neonates. The study population consisted of 44 infants (55 placements) who were admitted to the Takeda General Hospital between April 2012 and March 2013 and who required GT exchange. The sky blue method using indigo carmine (IC) was indicated for planned tube exchange only. Diluted IC was injected into the gastric space via the old GT just before the tube exchange. The tube was exchanged using a standard method. Then, we checked whether the diluted IC could be collected through the new GT or not. The reasons for GT placement were a gestational age of sky blue method was considered successful in 52 placements (94.4%), with the remaining 3 placements (5.6%) considered to be failures due to the inability to obtain IC from the gastric space. No adverse events were observed during the tube exchange period. Based on the results, the sky blue method can be considered to be reliable method for the confirmation of GT placement. These results also suggest that the number of radiologic evaluations performed to confirm correct replacement of the GT in infants can be reduced in the future.

Full Text Available This paper presents the isotropic placement of multiple optical mice for the velocity estimation of a mobile robot. It is assumed that there can be positional restriction on the installation of optical mice at the bottom of a mobile robot. First, the velocity kinematics of a mobile robot with an array of optical mice is obtained and the resulting Jacobian matrix is analysed symbolically. Second, the isotropic, anisotropic and singular optical mouse placements are identified, along with the corresponding characteristic lengths. Third, the least squares mobile robot velocity estimation from the noisy optical mouse velocity measurements is discussed. Finally, simulation results for several different placements of three optical mice are given.

2012-10-15

Purpose: To evaluate the clinical effectiveness of self-expandable metallic stents in seven patients with malignant gastroduodenal obstruction caused by inoperable hepatocellular carcinoma (HCC). Methods: Seven patients with gastroduodenal obstruction caused by advanced HCC underwent metallic stent placement from 2003 to 2010. These patients had total dysphagia (n = 5) or were able to eat only liquids (n = 2) before stent placement. Patients had Eastern Cooperative Oncology Group performance scores of 2 or 3, and Child-Pugh classification B or C. Results: Stent placement was technically successful in all seven patients (100%) and clinically successful in six (86%). Five patients could eat a soft diet, and one patient tolerated regular diet after stent placement. Stent-related obstructive jaundice occurred in one patient. One patient had hematemesis 11 days after stent placement. Overall mean survival was 51 days (range, 10-119 days). Stent patency was preserved in six patients with clinical success until death. Conclusion: Placement of a covered self-expandable metallic stent may offer good palliation in patients with gastroduodenal obstruction due to advanced HCC.

Observability-Based Guidance and Sensor Placement

Science.gov (United States)

Hinson, Brian T.

Control system performance is highly dependent on the quality of sensor information available. In a growing number of applications, however, the control task must be accomplished with limited sensing capabilities. This thesis addresses these types of problems from a control-theoretic point-of-view, leveraging system nonlinearities to improve sensing performance. Using measures of observability as an information quality metric, guidance trajectories and sensor distributions are designed to improve the quality of sensor information. An observability-based sensor placement algorithm is developed to compute optimal sensor configurations for a general nonlinear system. The algorithm utilizes a simulation of the nonlinear system as the source of input data, and convex optimization provides a scalable solution method. The sensor placement algorithm is applied to a study of gyroscopic sensing in insect wings. The sensor placement algorithm reveals information-rich areas on flexible insect wings, and a comparison to biological data suggests that insect wings are capable of acting as gyroscopic sensors. An observability-based guidance framework is developed for robotic navigation with limited inertial sensing. Guidance trajectories and algorithms are developed for range-only and bearing-only navigation that improve navigation accuracy. Simulations and experiments with an underwater vehicle demonstrate that the observability measure allows tuning of the navigation uncertainty.

Is the Routine Check Nephrostogram Following Percutaneous Antegrade Ureteric Stent Placement Necessary?

International Nuclear Information System (INIS)

Soh, Keng Chuan; Tay, Kiang Hiong; Tan, Bien Soo; MM Htoo, Austin; HG Lo, Richard; Lin, Shueh En

2008-01-01

Our aim was to review our experience with percutaneous antegrade ureteric stent (PAUS) placement and to determine if the routinely conducted check nephrostogram on the day following ureteric stent placement was necessary. Retrospective review of patients who had undergone PAUS placement between January 2004 and December 2005 was performed. There were 83 subjects (36 males, 47 females), with a mean age of 59.9 years (range, 22-94 years). Average follow-up duration was 7.1 months (range, 1-24 months). The most common indications for PAUS placement were ureteric obstruction due to metastatic disease (n = 56) and urinary calculi (n = 34). Technical success was 93.2% (96/103 attempts), with no major immediate procedure-related complications or mortalities. The Bard 7Fr Urosoft DJ Stent was used in more than 95% of the cases. Eighty-one of 89 (91.0%) check nephrostograms demonstrated a patent ureteric stent with resultant safety catheter removal. Three check nephrostograms revealed distal stent migration requiring repositioning by a goose-snare, while five others showed stent occlusion necessitating permanent external drainage by nephrostomy drainage catheter reinsertion. Following PAUS placement, the serum creatinine level improved or stabilized in 82% of patients. The serum creatinine outcome difference between the groups with benign and malignant indications for PAUS placement was not statistically significant (p = 0.145) but resolution of hydronephrosis was significantly better (p = 0.008) in patients with benign indications. Percutaneous antegrade ureteric stent placement is a safe and effective means of relief for ureteric obstruction. The check nephrostogram following ureteric stent placement was unnecessary in the majority of patients

[Family caregivers' adjustment to nursing home placement of older relatives].

Wang, Szu-Yao; Davies, Elizabeth

2007-06-01

The literature on the impact of nursing home placement of older parents on family caregivers is still incomplete. Family caregivers experience stress, shock, anxiety, fear, resistance, and guilt in the process of decision making. The literature has demonstrated that family caregivers continue to experience stress and problems after placing older relatives into a long term care facility. Cultural values impact on people's attitudes, values and expectations. Culture will therefore affect the care-giving experience. Relatively little information is available from Asian and multicultural societies. Identifying family caregiver experiences after nursing home placement can alert professionals to the need for family guidance prior to nursing home placement and assist in early identification of potential problems. This article reviews the literature and discusses the impact on family caregivers of making a decision for nursing home placement and dealing with the stress and challenges that persist after nursing home admission.

Clinical placements and nursing students' career planning: a qualitative exploration.

Many nursing students enter undergraduate programmes with preconceived ideas about their future nursing careers, and intend to practice in particular areas such as midwifery or paediatrics. Through clinical placements, students are exposed to different clinical areas and professional socialization is facilitated. However, little is known about the influence of clinical placements on students' career intentions. This paper reports nursing findings drawn from a large qualitative study conducted in Victoria, Australia that sought to explore the influence of health professional students' clinical placements on their future career intentions. Participants were invited to be involved in either face-to-face or focus group interviews depending upon their own preference. Thematic data analysis revealed three main themes: 're-affirming career choice', 'working in a particular area' and 'work location'. Findings from the study add to our understanding of factors influencing nursing students' planning for their future careers including the impact of clinical placements.

2007-01-01

Individual Placement and Support is a vocational rehabilitation programme for people with severe mental illness, which was implemented during the period 2003-2005 at four locations in the Netherlands. To investigate the degree of compliance with the Individual Placement and Support programme, the factors that hindered or facilitated its implementation, and the results. The degree of compliance was assessed using the Individual Placement and Support fidelity scale. Data regarding the factors that hindered or facilitated the implementation were collected via interviews and monitoring. In addition, data were collected on patient characteristics, the support provided and the jobs found. None of the locations achieved the highest level of compliance, although two locations came close. Eighteen per cent of the 316 patients were helped to find a regular job. The most important obstacles to implementation were loss of vocational team members, project leaders' lack of time, lack of finance, and insufficient cooperation between the organisations involved. The most important facilitating factors were the skills and commitment of the vocational team member(s) and the integration of the vocational teammember(s) and the mental health team. It is not easy to implement Individual Placement and Support. However, if more attention is given to good project management, Individual Placement and Support can succeed in the Netherlands.

Anterior mediastinal tracheostomy (AMT) is performed to establish an airway after resection of advanced tumors in the cervicothoracic region. We report a case of successful placement of a covered retrievable self-expandable nitinol stent for a stoma stricture that developed after AMT in a patient with adenoid cystic carcinoma of the trachea. Two stent placements and removals, at two and three months after their initial placement, were performed due to loosening of the stents. Although we did not achieve long-term results as the patient died of massive hemorrhage, the stent placement was both feasible and safe, thus suggesting that temporary stent placement may be a valuable option for treating stoma stricture occurring after AMT.

Kalantar, D.

1999-01-01

The input that has been provided on the NIF experiment setup sheets has allowed us to review the diagnostic and DIM placement as well as the baseline unconverted light management plan. We have done an iteration to identify common diagnostic lines of sight, and with additional requirements defined by specific experiments, we propose (1) a baseline plan for DIM placement requiring only five DIMs that may be moved between up to seven DIM ports, and (2) a modified baseline unconverted light management plan. We request additional input to identify primary vs. secondary diagnostics for each experiment definition

The aim of this study was to profile students undertaking placements at University Departments of Rural Health (UDRHs) and investigate factors affecting students' satisfaction and intention to enter rural practice. Cross-sectional survey comprising 21 core questions used by all UDRHs. Eleven UDRHs across Australia that support students' placements in regional, rural and remote locations. Medical, nursing and allied health students who participated in UDRH placements between July 2014 and November 2015 and completed the questionnaire. Key dependent variables were placement satisfaction and rural practice intention. Descriptive variables were age, gender, Aboriginal or Torres Strait Islander (ATSI) background, location of placement, healthcare discipline, year of study and type and length of placement. A total of 3328 students responded. The sample was predominantly female (79%), the mean age was 26.0 years and 1.8% identified as ATSI. Most placements (69%) were >2 but ≤12 weeks, 80% were in Modified Monash 3, 4 or 5 geographical locations. Public hospitals and community health made up 63% of placements. Students satisfied with their placement had 2.33 higher odds of rural practice intention. Those satisfied with Indigenous cultural training, workplace supervision, access to education resources and accommodation had higher odds of overall satisfaction and post-placement rural practice intention. The majority of students were highly satisfied with their placement and the support provided by rural clinicians and the UDRHs. UDRHs are well placed to provide health professional students with highly satisfactory placements that foster rural practice intention. © 2017 National Rural Health Alliance Inc.

Retrograde or antegrade double-pigtail stent placement for malignant ureteric obstruction?

International Nuclear Information System (INIS)

Uthappa, M.C.; Cowan, N.C.

2005-01-01

AIM: To determine the optimum approach for double-pigtail stent placement in malignant ureteric obstruction. PATIENTS AND METHODS: Retrograde stent placement was attempted in a consecutive series of patients presenting with malignant ureteric obstruction. If retrograde stent placement was unsuccessful, percutaneous nephrostomy was performed immediately followed by elective antegrade stent placement. Identical digital C-arm fluoroscopy for image-guidance and conditions for anaesthesia and analgesia were employed for both retrograde and antegrade procedures. Identical 8 Fr (20-26 cm) double-pigtail hydrophilic coated stents were used for each approach. RESULTS: Retrograde placement was attempted in 50 ureters in 30 patients {19 male, 11 female, average age 61.4 yr (range 29-90 yr)} over a 24-month period. The success rate for retrograde ureteric stent placement was 50% (n=25/50). Technical failures were due to failure to identify the ureteric orifice (n=22), failure to cross the stricture (n=1), failure to pass the stent (n=1) and failure to pass a 4 Fr catheter (n=1). Antegrade placement was attempted in 25 ureters with a success rate of 96% (n=24/25). Failure in the one case was due to inability to cross an upper third stricture secondary to pyeloureteritis cystica. CONCLUSION: It is suggested that retrograde route should be the initial approach if imaging shows no involvement of ureteric orifice (UO), when nephrostomy is technically very difficult or in cases of solitary kidney. The antegrade route is preferred if imaging shows tumour occlusion of the UO or if there is a tight stricture very close to the uretero-vesical junction (UVJ) making purchase within the ureter difficult for crossing the stricture

To demonstrate the feasibility and clinical efficacy of self-expanding, covered metallic stent placement for the palliative treatment of malignant gastric obstruction. Under fluoroscopic guidance, the placement of self-expanding, covered stents was attempted in 23 patients (age range, 31-78 years) with inoperable or recurrent gastric malignancies. All 23 suffered dysphagia and/or vomiting after the ingestion of soft foods, or swallowing difficulty. Three different types of self-expanding, covered metallic stents were used and in all patients, these were placed perorally using over the guide wire technique. Success was defined both technically and clinically. Stent placement was technically successful in 19 patients (82.6%) but because the guidewire failed to successfully negotiate the sites at which there was obstruction, was unsuccessful in four (17.4%). Stent placement was well tolerated in all patients except one, in whom an acutely angled efferent loop from remnant stomach was present. In this case, stent placement required a strong metallic guidewire. After placement, 17 of the 19 patients (89.5%) were able to ingest solid and/or soft foods without dysphagia and showed a markedly decreased incidence of vomiting. Two others showed some improvement in the frequency of vomiting but were able to ingest only a liquid diet. In one patient, the stent migrated two days after the procedure. During the follow-up period of 2-7 months (mean, 74 days), there were no clinically significant complications. For the short-term palliative treatment of patients with gastric inlet or outlet obstruction, the placement of self-expanding metallic stents has proven relatively easy and safe, as well as reasonably effective.

Efficient placement of structural dynamics sensors on the space station

Science.gov (United States)

Lepanto, Janet A.; Shepard, G. Dudley

1987-01-01

System identification of the space station dynamic model will require flight data from a finite number of judiciously placed sensors on it. The placement of structural dynamics sensors on the space station is a particularly challenging problem because the station will not be deployed in a single mission. Given that the build-up sequence and the final configuration for the space station are currently undetermined, a procedure for sensor placement was developed using the assembly flights 1 to 7 of the rephased dual keel space station as an example. The procedure presented approaches the problem of placing the sensors from an engineering, as opposed to a mathematical, point of view. In addition to locating a finite number of sensors, the procedure addresses the issues of unobserved structural modes, dominant structural modes, and the trade-offs involved in sensor placement for space station. This procedure for sensor placement will be applied to revised, and potentially more detailed, finite element models of the space station configuration and assembly sequence.

Accounting for L2 learners’ errors in word stress placement

Full Text Available Stress placement in English words is governed by highly complicated rules. Thus, assigning stress correctly in English words has been a challenging task for L2 learners, especially Indonesian learners since their L1 does not recognize such stress system. This study explores the production of English word stress by 30 university students. The method used for this study is immediate repetition task. Participants are instructed to identify the stress placement of 80 English words which are auditorily presented as stimuli and immediately repeat the words with correct stress placement. The objectives of this study are to find out whether English word stress placement is problematic for L2 learners and to investigate the phonological factors which account for these problems. Research reveals that L2 learners have different ability in producing the stress, but three-syllable words are more problematic than two-syllable words. Moreover, misplacement of stress is caused by, among others, the influence of vowel lenght and vowel height.

Placement shift, sibling relationship quality, and child outcomes in foster care: a controlled study.

Sibling unity during family transitions is considered a protective factor for child behavior problems, but there is little empirical support for the widespread child protection policy of placing siblings together in foster care. In a prospective study of 156 maltreated children, siblings were classified in 1 of 3 placement groups: continuously together (n = 110), continuously apart (n = 22), and disrupted placement (siblings placed together were separated; n = 24). Changes in child adjustment as a function of sibling relationship and placement group were examined. Sibling positivity predicted lower child problems at follow-up (about 14 months later), while sibling negativity predicted higher child problems. Placement group did not affect child behavior problems at follow-up; however, compared to siblings in continuous placement (either together or apart), siblings in disrupted placement with high initial behavior problems were rated as having fewer problems at follow-up, while siblings in disrupted placement with low initial behavior problems were rated as having more problems at follow-up. These findings highlight the importance of considering relationships between siblings and the risk that one poses to another before early placement decisions are made.

The dental literature has reported vertical soft tissue changes that can occur with immediate implant placement, bone grafting, and provisional restoration ranging from a gain or loss of 1.0 mm. However, little is known of the effects of facial-palatal collapse of the ridge due to these clinical procedures. Based upon treatment modalities rendered, an ensuing contour change can occur with significant negative esthetic consequences. The results of a retrospective clinical cohort study evaluating the change in horizontal ridge dimension associated with implant placement in anterior postextraction sockets are presented for four treatment groups: (1) group no BGPR = no bone graft and no provisional restoration; (2) group PR = no bone graft, provisional restoration; (3) group BG = bone graft, no provisional restoration; and (4) group BGPR = bone graft, provisional restoration. Bone grafting at the time of implant placement into the gap in combination with a contoured healing abutment or a provisional restoration resulted in the smallest amount of ridge contour change. Therefore, it is recommended to place a bone graft and contoured healing abutment or provisional restoration at the time of flapless postextraction socket implant placement.

Currently in the Australian higher education sector, the productivity benefits of occupational therapy clinical education placements are a contested issue. This article will report results of a study that developed a methodology for documenting time use during placements and investigated the productivity changes associated with occupational therapy clinical education placements in Queensland, Australia. Supervisors' and students' time use during placements and how this changed for supervisors compared to pre- and post-placement is also presented. Using a cohort survey design, participants were students from two Queensland universities, and their supervisors employed by Queensland Health. Time use was recorded in 30 minute blocks according to particular categories. There was a significant increase in supervisors' time spent in patient care activities (F = 94.011(2,12.37 df) , P increasing between pre- and during placement (P = 0.028). There was a significant decrease in supervisors' time spent in placement activities (F = 5.133(2,19.18 df) , P = 0.016) from during to post-placement. Students spent more time than supervisors in patient care activities while on placement. A novel method for reporting productivity and time-use changes during clinical education programs for occupational therapy has been applied. Supervisors spent considerable time in assessing and managing students and their clinical education role should be seen as core business in standard occupational therapy practice. This paper will contribute to future assessments of the economic impact of student placements for allied health disciplines. © 2011 The Authors.

placement subproblems are created by partitioning and then processed concurrently by multiple worker threads that are run on multiple cores of the same processor. Our main goal is to investigate the speedup that can be achieved with this simple approach compared to previous approaches that were based on distributed computing. The new hybrid parallel placement algorithm achieves an average speedup of 2.5× using four worker threads, while the total wire length and circuit delay after routing are minimally degraded.

The study aimed to establish current levels of overseas volunteering and placement activity across all staff grades within the National Health Service (NHS) in the North West of England. Cross-sectional survey. Descriptive statistics. 4 main regional hospitals in the North West of England, and additional NHS staff training events. Convenience sample of NHS staff (n=911). 911 NHS staff took part in the survey. The medical and dental staff group returned the highest number of responses (32.1%). 42% of staff reported some form of overseas volunteering or placement experience. Most staff took an international placement as students (33.6% men; 40.6% women). Medium-term placements were undertaken by 46.7% of men, and 52.5% of women. Settlement stays (ie, over 1 year) were reported by 7.6% men, and 8.3% women). The majority of respondents engaged in international placement were from the age groups incorporating 'below 25' to '41-50' (74%). Multiple placement experiences were uncommon: 2.5% of respondents reported three periods of overseas activity, and 1.5% reported four. All those with multiple placement experience came from the staff groups incorporating midwife/nurse/health visitor, and medical and dental. This survey captured a snapshot of current levels of volunteering and overseas placement activity across NHS staff grades in the North West. Owing to relatively homogenous organisational structures, findings are likely to broadly represent the position across the organisation as a whole. Although some degree of overseas placement activity is undertaken by a relatively high proportion of NHS staff, such activity is currently heavily skewed towards higher clinical staff grades. Significant numbers of allied health professionals and equivalent non-clinical cadres also report overseas experience, and we anticipate that the numbers will continue to rise if current policy initiatives gain momentum.

Tobey, Emily A; Rekart, Deborah; Buckley, Kristi; Geers, Ann E

2004-05-01

To examine the impact of classroom placement and mode of communication on speech intelligibility scores in children aged 8 to 9 years using multichannel cochlear implants. Classroom placement (special education, partial mainstream, and full mainstream) and mode of communication (total communication and auditory-oral) reported via parental rating scales before and 4 times after implantation were the independent variables. Speech intelligibility scores obtained at 8 to 9 years of age were the dependent variables. The study included 131 congenitally deafened children between the ages of 8 and 9 years who received a multichannel cochlear implant before the age of 5 years. Higher speech intelligibility scores at 8 to 9 years of age were significantly associated with enrollment in auditory-oral programs rather than enrollment in total communication programs, regardless of when the mode of communication was used (before or after implantation). Speech intelligibility at 8 to 9 years of age was not significantly influenced by classroom placement before implantation, regardless of mode of communication. After implantation, however, there were significant associations between classroom placement and speech intelligibility scores at 8 to 9 years of age. Higher speech intelligibility scores at 8 to 9 years of age were associated with classroom exposure to normal-hearing peers in full or partial mainstream placements than in self-contained, special education placements. Higher speech intelligibility scores in 8- to 9-year-old congenitally deafened cochlear implant recipients were associated with educational settings that emphasize oral communication development. Educational environments that incorporate exposure to normal-hearing peers were also associated with higher speech intelligibility scores at 8 to 9 years of age.

2016-01-01

Object The Management of Myelomeningocele Study (MOMS) was a multicenter randomized trial comparing the safety and efficacy of prenatal and postnatal closure of myelomeningocele. The trial was stopped early because of the demonstrated efficacy of prenatal surgery, and outcomes on 158 of 183 pregnancies were reported. Here, the authors update the 1-year outcomes for the complete trial, analyze the primary and related outcomes, and evaluate whether specific prerandomization risk factors are associated with prenatal surgery benefit. Methods The primary outcome was a composite of fetal loss or any of the following: infant death, CSF shunt placement, or meeting the prespecified criteria for shunt placement. Primary outcome, actual shunt placement, and shunt revision rates for prenatal versus postnatal repair were compared. The shunt criteria were reassessed to determine which were most concordant with practice, and a new composite outcome was created from the primary outcome by replacing the original criteria for CSF shunt placement with the revised criteria. The authors used logistic regression to estimate whether there were interactions between the type of surgery and known prenatal risk factors (lesion level, gestational age, degree of hindbrain herniation, and ventricle size) for shunt placement, and to determine which factors were associated with shunting among those infants who underwent prenatal surgery. Results Ninety-one women were randomized to prenatal surgery and 92 to postnatal repair. The primary outcome occurred in 73% of infants in the prenatal surgery group and in 98% in the postnatal group (p < 0.0001). Actual rates of shunt placement were only 44% and 84% in the 2 groups, respectively (p < 0.0001). The authors revised the most commonly met criterion to require overt clinical signs of increased intracranial pressure, defined as split sutures, bulging fontanelle, or sunsetting eyes, in addition to increasing head circumference or hydrocephalus.

1979-12-01

A series of experiments with rice and wheat were carried out to study the efficiency of nitrogen placement methods and slow-release nitrogen fertilizers for these two crops using N-15-labelled fertilizer. The results show that (1) reduced N levels, of the order of 75 percent of the full recommended dose, are equally efficient as the full dose for wheat. The yield of rice grain increased with the increased dose of nitrogen; (2) Point placement of fertilizers for rice was superior to broadcast application in terms of uptake and yield. For optimum yield of wheat grain, urea should perferably be applied as a single dose banded between the rows at 5 cm depth or by broadcasting and incorporation in the soil at the time of sowing; (3) Sulphur-coated urea (SCU) at a comparable dose and mode of application gave better yields of rice grain than the application of urea and IBDU (Isobutylidine Diurea); (4) More nitrogen was taken up by wheat when SCU was applied. The best uptake was when it was applied half at sowing and half at tillering. The nitrogen uptake from the SCU by point placement was better for rice plants than broadcast application and was higher in magnitude than the IBDU

Substantial changes in mastery perceptions of dementia caregivers with the placement of a care recipient.

Infurna, Frank J; Gerstorf, Denis; Zarit, Steven H

2013-03-01

The current study examined how a key component of caregiving stress processes, global mastery perceptions, changes with placing the care recipient in a nursing home or institution. We also explored the role of primary stressors in accounting for mastery changes with placement and whether characteristics of the caregiver and care recipient moderate reactions to placement. We applied multiphase growth curve models to prospective longitudinal data from 271 caregivers in the Caregiver Stress and Coping Study who experienced placement of their care recipient. Using a time-to/from-placement metric, we found that caregivers typically experienced declines in mastery preceding placement, followed by a significant increase within 1 year after placement and further increases thereafter. Corresponding changes in primary stressors (role overload) mediated the placement-related increase in mastery. Caregivers who reported more depressive symptoms and activities of daily living/instrumental activities of daily living dependencies of the care recipient were more likely to experience larger placement-related increases in mastery perceptions. Our findings suggest that placement alters psychological resources of caregivers and this effect is driven by corresponding changes in primary stressors. Findings also underscore the importance of examining change processes across salient life events and transitions.

Implementation of the evidence review on best practice for confirming the correct placement of nasogastric tube in patients in an acute care hospital.

2011-03-01

Nasogastric (NG) tube is a device passed through the gastrointestinal tract of patients for the purpose of feeding, gastric decompression and medication administration. However, a small risk involved in the process is that the tube may be misplaced into the trachea during insertion or may get displaced at a later stage, leading to disastrous results. Recent adverse incidences arising out of the misplacement of NG tube raised concerns among the nursing and medical community and the Patient Safety Officer of the hospital. The Evidence Based Nursing Unit, in collaboration with some of the key nursing leaders in nursing administration, was tasked to explore and institute the current best practice in confirming the correct placement of NG tube. The aim of this project was to institute the best practice to confirm the correct placement of NG tube in patients in an acute care hospital setting. The project comprised of a few stages. The first stage involved reviewing the existing recommendations and guidelines on the methods for checking correct NG tube placement. The second stage involved incorporation of the change of practice into the clinical setting. The final stage was to monitor and evaluate the impact of the new practice on the patients, nurses and other healthcare professionals. Evidence search from guidelines and journals supported the test that used pH indicator instead of the litmus test. There is no evidence that supports the method of auscultation and bubbling to confirm correct NG tube placement in the absence of aspirate. Radiology remains the 'gold standard' for checking correct NG tube placement. The revised method of NG tube placement and workflow was incorporated in the revised Standard Operating Procedures. A total of 17 roadshows were conducted to create awareness regarding the new method amongst the nurses, and the implementation of the revised method and workflow was commenced on 3 November 2008. The initial audit conducted 1 month after the

Restrictive educational placements increase adolescent risks for students with early-starting conduct problems.

Powers, Christopher J; Bierman, Karen L; Coffman, Donna L

2016-08-01

Students with early-starting conduct problems often do poorly in school; they are disproportionately placed in restrictive educational placements outside of mainstream classrooms. Although intended to benefit students, research suggests that restrictive placements may exacerbate the maladjustment of youth with conduct problems. Mixed findings, small samples, and flawed designs limit the utility of existing research. This study examined the impact of restrictive educational placements on three adolescent outcomes (high school noncompletion, conduct disorder, depressive symptoms) in a sample of 861 students with early-starting conduct problems followed longitudinally from kindergarten (age 5-6). Causal modeling with propensity scores was used to adjust for confounding factors associated with restrictive placements. Analyses explored the timing of placement (elementary vs. secondary school) and moderation of impact by initial problem severity. Restrictive educational placement in secondary school (but not in elementary school) was iatrogenic, increasing the risk of high school noncompletion and the severity of adolescent conduct disorder. Negative effects were amplified for students with conduct problem behavior with less cognitive impairment. To avoid harm to students and to society, schools must find alternatives to restrictive placements for students with conduct problems in secondary school, particularly when these students do not have cognitive impairments that might warrant specialized educational supports. © 2015 Association for Child and Adolescent Mental Health.

A shared experience of fragmentation: making sense of foster placement breakdown.

Rostill-Brookes, Helen; Larkin, Michael; Toms, Amy; Churchman, Clare

2011-01-01

Multiple placement transitions have been associated with poorer psychosocial outcomes for children growing up in local authority care. However, although there is an expanding literature examining the risk and protective factors connected with placement breakdown, very few studies have explored the quality of the move experience for those most closely involved with it. Our study considered how young people, foster carers and social workers made sense of unplanned placements' endings. Bringing together the lived experiences of these key stakeholders in the placement system added a novel dimension to existing research knowledge. What emerged from our analysis was evidence of a pervasive and shared emotional experience; all of the participants were affected by the breakdown irrespective of age, experience, or professional role. However, despite many commonalities, there was also a strong sense of fragmentation between the groups, which was characterised by discourses of mistrust and miscommunication. This meant that emotional reactions to the breakdown were often suppressed or dismissed, resentments built-up and attempts to find a solution were thwarted by silence or angry recrimination. These findings raise real challenges for practice and policy development. In particular, they stress the importance of shared and meaningful dialogue between all key stakeholders within the social care system, the need for more effective and timely support when placements are in crisis and opportunities for those most closely involved with the placement breakdown to process the emotional experience.

International medical volunteering has grown in recent decades. It has the potential to benefit and harm the volunteer and host countries; but there is a paucity of literature on the impacts of international medical volunteering and a need to find ways to optimise the benefits of such placements. In this study, one example of international medical volunteering was examined involving British GPs on short-term placements in Nepal. The intention was to explore the expectations and experiences of the local health workers, volunteers, and host organisation to try and understand what makes volunteer placements work. Qualitative study of key informant interviews. Stakeholders of a short-term international medical volunteer (IMV) placement programme in Nepal. Key informant interviews were carried out via face-to-face or telephone/internet interviews with five previous volunteers, three representatives from a non-governmental organisation providing placements, and five local health workers in Nepal who had had contact with the IMVs. Interviews were recorded, transcribed, and analysed using standard thematic framework approaches. All the stakeholders had their own specific motives for participating in the IMV programme. The relationship between volunteers and the Nepalese health workers was complex and characterised by discrepant and occasionally unrealistic expectations. Managing these different expectations was challenging. Contextual issues and cultural differences are important considerations in medical volunteer programmes, and this study highlights the importance of robust preparation pre-placement for the volunteer and host to ensure positive outcomes. © British Journal of General Practice 2014.

Radiography students' clinical placement experiences in MRI: A phenomenological study

International Nuclear Information System (INIS)

Portanier Mifsud, Claude; Castillo, Joseph; Portelli, Jonathan Loui

2015-01-01

Purpose: The purpose of this study was to gain an insight into radiography students' clinical practice experiences within an MRI unit of a large teaching hospital in Malta. The underlying objectives of the study were to identify and explore the descriptions and meanings of the MRI clinical experiences of students. Methods: Five students, independently undergoing their clinical placements in MRI were asked to write a diary about their daily experiences. Each student then participated in a follow up interview. Data analysis was based on Husserls' phenomenological approach. Results: Eight themes emerged from the data analysed. Students described their experience as one mainly based on observation, where, during their placements, they observed radiographers at work. In this respect, students described their experience as lacking ‘hands on practice’. Students indicated that they felt uncomfortable, unsupervised and unwelcome most of the time. They also expressed the need to feel useful and part of the MRI team during their placement and so they tried to help the team in areas such as patient screening. This helped them build confidence. Learning in MRI was specifically based on the university tasks prescribed and possibly there was no motivation to learn more. The students also described their experience as varied and different when compared to other placements. Conclusion: This study provides a rare insight into radiography students' placement experiences in MRI and should enable the supervising radiographer and educator to obtain a deeper appreciation of the clinical placement experience

To examine understandings of global health issues among nursing students following participation in an international clinical placement during their pre-registration university education. Universities use international clinical placements, especially in developing countries, to develop cultural awareness in students; however, little is known about the longer term influences on students' understandings of global nursing. A retrospective cross-sectional design was used, using an exploratory, descriptive qualitative approach. Individual semi-structured interviews were conducted in 2014 with a purposive sample of 25 pre-registration nursing students from four Western Australian universities who undertook clinical placements across five countries. Data were analysed using inductive thematic analysis. Findings highlight that students developed new understandings around health systems including fragility of resource access, differences in clinical practice and variances in nursing roles between settings. Students also experienced challenges but were able to appreciate alternative world viewpoints. International clinical placements can develop greater awareness and help students form realistic strategies for using their nursing skills globally. Pre-placement training in cultural awareness and health system realities, along with strong supervisory support, is critical to success. © 2017 John Wiley & Sons Ltd.

Wavelength converter placement for different RWA algorithms in wavelength-routed all-optical networks

Science.gov (United States)

Chu, Xiaowen; Li, Bo; Chlamtac, Imrich

2002-07-01

Sparse wavelength conversion and appropriate routing and wavelength assignment (RWA) algorithms are the two key factors in improving the blocking performance in wavelength-routed all-optical networks. It has been shown that the optimal placement of a limited number of wavelength converters in an arbitrary mesh network is an NP complete problem. There have been various heuristic algorithms proposed in the literature, in which most of them assume that a static routing and random wavelength assignment RWA algorithm is employed. However, the existing work shows that fixed-alternate routing and dynamic routing RWA algorithms can achieve much better blocking performance. Our study in this paper further demonstrates that the wavelength converter placement and RWA algorithms are closely related in the sense that a well designed wavelength converter placement mechanism for a particular RWA algorithm might not work well with a different RWA algorithm. Therefore, the wavelength converter placement and the RWA have to be considered jointly. The objective of this paper is to investigate the wavelength converter placement problem under fixed-alternate routing algorithm and least-loaded routing algorithm. Under the fixed-alternate routing algorithm, we propose a heuristic algorithm called Minimum Blocking Probability First (MBPF) algorithm for wavelength converter placement. Under the least-loaded routing algorithm, we propose a heuristic converter placement algorithm called Weighted Maximum Segment Length (WMSL) algorithm. The objective of the converter placement algorithm is to minimize the overall blocking probability. Extensive simulation studies have been carried out over three typical mesh networks, including the 14-node NSFNET, 19-node EON and 38-node CTNET. We observe that the proposed algorithms not only outperform existing wavelength converter placement algorithms by a large margin, but they also can achieve almost the same performance comparing with full wavelength

Endoscopic placement of self-expandable metallic stents is reportedly effective for gastric outlet obstructions due to advanced gastric cancer, and is less invasive than gastrojejunostomy. For patients who have good performance status, we administer chemotherapy after stent placement, although the safety and feasibility of this chemotherapy have not yet been discussed in full. Between 2011 and 2015, 15 patients at our institution underwent endoscopic gastroduodenal stent placement for gastric outlet obstruction due to gastric cancer. Eleven of these patients were administered chemotherapy after stent placement. In our case series, we did not observe any specific adverse event caused by stent placement plus chemotherapy. Adverse events after chemotherapy included anemia of CTCAE Grade 3 in 7 patients. Stent-in-stent placement was needed in 2 patients. Neither stent migration nor perforation was observed. Therefore, chemotherapy after stent placement for gastric outlet obstruction due to gastric cancer was considered safe and feasible. Stent placement is useful not only as palliative care for patients with terminal-stage disease, but also as one of the multimodal therapeutic strategies for gastric cancer.

To observe student nurses' overall and moment-specific hand hygiene compliance during clinical placement. Hand hygiene is the single most important measure to prevent healthcare-associated infections. However, research has shown low compliance among healthcare workers. During clinical placements, student nurses perform various nursing tasks and procedures to a large number of patients, requiring extensive patient contact. It is crucial that they practice correct hand hygiene to prevent healthcare-associated infections. Open, standardised and nonparticipating observations. Twenty-nine student nurses were observed three times for 20 ± 10 min during clinical placement in a Norwegian university hospital. To measure compliance, we used WHO's Hand Hygiene Observation tool, based on the model "My five moments for hand hygiene". Overall hand hygiene compliance in the student group was 83.5%. Highest moment-specific compliance was after touching patient surroundings, after touching patients and after body fluid exposure risk. Lowest moment-specific compliance was recorded before touching patients or patient surroundings, and before clean/aseptic procedures. Nurse education needs to be improved both theoretically and during clinical placements in order to advance and sustain compliance among student nurses. Increasing healthcare workers' compliance with hand hygiene guidelines remains a challenge to the clinical community. In order to reduce healthcare-associated infections, it is important to educate student nurses to comply with the guidelines during clinical placements. Identifying student nurses' hand hygiene performance is the first step towards developing teaching methods to improve and sustain their overall and moment-specific compliance. As a measure to ensure student compliance during clinical placements, mentors should be aware of their influence on students' performance, act as hand hygiene ambassadors, encourage students to comply with established guidelines

Research on media induced food choices of children has not sufficiently investigated whether food placements of snacks high in nutritional value can strengthen children's healthy eating behavior. Furthermore, we lack knowledge about the moderating role of children's individual characteristics such as parental food-related mediation or BMI. The current study combines data from an experiment involving children with a survey of their parents. We exposed children to a cartoon either containing no food placements, placements of mandarins (i.e., snack high in nutritional value), or placements of fruit gums (i.e., snack low in nutritional value). Afterwards, food consumption was measured by giving children the option to choose between fruit gums or mandarins. Children in both snack placement conditions showed stronger preference for the snack low in nutritional value (i.e., fruit gum) compared to the control group. Interestingly, neither restrictive nor active food-related mediation prevented the effects of the placements on children's choice of snacks low in nutritional value. Compared to children with a low BMI, children with high BMI levels had a stronger disposition to choose the fruit gums if a snack high in nutritional value (i.e., mandarin) was presented. Thus, making snacks high in nutritional attractive for children through media presentation might need stronger persuasive cues. Copyright © 2017 Elsevier Ltd. All rights reserved.

A triaxial accelerometer monkey algorithm for optimal sensor placement in structural health monitoring

Science.gov (United States)

Jia, Jingqing; Feng, Shuo; Liu, Wei

2015-06-01

Optimal sensor placement (OSP) technique is a vital part of the field of structural health monitoring (SHM). Triaxial accelerometers have been widely used in the SHM of large-scale structures in recent years. Triaxial accelerometers must be placed in such a way that all of the important dynamic information is obtained. At the same time, the sensor configuration must be optimal, so that the test resources are conserved. The recommended practice is to select proper degrees of freedom (DOF) based upon several criteria and the triaxial accelerometers are placed at the nodes corresponding to these DOFs. This results in non-optimal placement of many accelerometers. A ‘triaxial accelerometer monkey algorithm’ (TAMA) is presented in this paper to solve OSP problems of triaxial accelerometers. The EFI3 measurement theory is modified and involved in the objective function to make it more adaptable in the OSP technique of triaxial accelerometers. A method of calculating the threshold value based on probability theory is proposed to improve the healthy rate of monkeys in a troop generation process. Meanwhile, the processes of harmony ladder climb and scanning watch jump are proposed and given in detail. Finally, Xinghai NO.1 Bridge in Dalian is implemented to demonstrate the effectiveness of TAMA. The final results obtained by TAMA are compared with those of the original monkey algorithm and EFI3 measurement, which show that TAMA can improve computational efficiency and get a better sensor configuration.

Allott, Kelly A; Turner, Luana R; Chinnery, Gina L; Killackey, Eoin J; Nuechterlein, Keith H

Individual Placement and Support is the most defined and evidence-based approach to supported employment for severe mental illness, including recent-onset psychosis. However, there is limited evidence or detailed guidelines informing the management of mental illness disclosure to educators or employers when delivering individual placement and support. In this paper, we describe the initial disclosure preferences of young people with recent-onset psychosis enrolled in individual placement and support and provide guidance for managing disclosure when delivering Individual Placement and Support with this population. Drawing from sites in Melbourne, Australia and Los Angeles, USA, clients' initial disclosure preferences were examined. We describe approaches to providing individual placement and support when no disclosure is permitted compared with when disclosure is permitted, including two illustrative case vignettes. No disclosure of mental illness or disability was requested by 54-59% of clients; 41-46% of clients permitted partial or complete disclosure. The 'no disclosure' scenario required the individual placement and support worker to provide support 'behind the scenes', whereas when disclosure was permitted, the individual placement and support worker could have contact with instructors/employers and work 'on the front lines'. The case vignettes illustrate how both approaches can lead to successful vocational outcomes. We found that Individual Placement and Support can be provided in an educative, flexible, creative and collaborative manner according to client disclosure preferences. We suggest that disclosure preferences do not prevent successful vocational outcomes, although this supposition requires empirical investigation. © 2013 Wiley Publishing Asia Pty Ltd.

To evaluate inferior vena cava (IVC) filter placement and retrieval rates among radiologists, vascular surgeons, cardiologists, other surgeons, and all other health care providers for Medicare fee-for-service beneficiaries in the years 2012-2015. The nationwide Medicare Physician/Supplier Procedure Summary Master Files were used to determine the volume and utilization rate of IVC filter placement, IVC filter repositioning, and IVC filter retrieval, which correspond to procedure codes 37191, 37192, and 37193, respectively. Procedural code 37193 was not available before 2012, so data were reviewed for the years 2012-2015. The total volume of Medicare IVC filter placement decreased from 57,785 in 2012 to 44,378 in 2015, with radiologists responsible for 60% of all filter placements. Volume of IVC filter placement declined across all specialties, including radiologists, who placed 33,744 in 2012 and 27,957 in 2015. In contrast, total retrieval of IVC filters increased from 4,060 removals in 2012 to 6,166 in 2015. Retrieval rate per 100,000 Medicare beneficiaries increased from 11 in 2012 to 16 in 2015. Radiologists removed the bulk of the filters: 64% in both 2012 and 2015. Vascular surgeons, cardiologists, and other surgeons retrieved, respectively, 20%, 10%, and 5% of all IVC filters in 2012 and 22%, 9%, and 5% in 2015. From 2012 to 2015, IVC filter placement steadily decreased across all specialties. Retrieval rate of IVC filters continued to rise over the same period. Radiologists were responsible for the majority of IVC filter placements and retrievals. Copyright © 2017 SIR. Published by Elsevier Inc. All rights reserved.

Unilateral placement of the Adiana device after failed bilateral placement of the Essure device for hysteroscopic sterilization.

Science.gov (United States)

Gimpelson, Richard J; Wagner, Corey A

2010-01-01

This case report outlines the successful completion of hysteroscopic sterilization using the Adiana Permanent Contraception device (Hologic, Inc., Bedford, MA) after failure of multiple attempts to bilaterally place the Essure Permanent Birth Control system (Conceptus Inc., Mountain View, CA). The patient desired hysteroscopic sterilization using the Essure system. Although the first coil was easily placed in the right ostium, the second coil could not be passed beyond 2.4 cm into the left ostium. Inasmuch as the Adiana system needs to be passed only 1.4 cm into the ostium, this was found to be adequate for appropriate placement of the implant. Adiana may be an effective alternative to Essure, especially in patients in whom tubal stricture or spasm prevents Essure placement. Copyright © 2010 AAGL. Published by Elsevier Inc.

2004-01-01

To investigate the feasibility of port catheter placement following a biliary stent placement. We employed 14 mongrel dogs as test subject and after the puncture of their gaIl bladders using sonographic guidance, a 10-mm in diameter metallic stent was placed at the common duct. In 12 dogs, a 6.3 F port catheter was placed into the duodenum through the common duct and a port was secured at the subcutaneous space following stent placement. As a control group, an 8.5 F drain tube was placed into the gallbladder without port catheter placement in the remaining two dogs. Irrigation of the bile duct was performed every week by injection of saline into the port, and the port catheter was replaced three weeks later in two dogs. Information relating to the success of the procedure, complications and the five-week follow-up cholangiographic findings were obtained. Placement of a biliary stent and a port catheter was technically successful in 13 (93%) dogs, while stent migration (n=3), gallbladder rupture (n=1) and death (n=5) due to subcutaneous abscess and peritonitis also occurred. The follow-up was achieved in eight dogs (seven dogs with a port catheter placement and one dog with a drain tube placement). Irrigation of the bile duct and port catheter replacement were successfully achieved without any complications. Cholangiograms obtained five weeks after stent placement showed diffuse biliary dilation with granulation tissue formation. However, focal biliary stricture was seen in one dog with stent placement alone. Placement of a port catheter following biliary stent placement seems to be feasible. However, further investigation is necessary to reduce the current complications

2015-09-01

The aim of this study was to revisit the available scientific literature regarding perioperative antibiotics in conjunction with implant placement by combining the recommended methods for systematic reviews and complex systematic reviews. A search of Medline (OVID), The Cochrane Library (Wiley), EMBASE, PubMed and Health technology assessment (HTA) organizations was performed, in addition to a complementary hand-search. Selected systematic reviews and primary studies were assessed using GRADE and AMSTAR, respectively. A meta-analysis was performed. The literature search identified 846 papers of which 10 primary studies and seven systematic reviews were included. Quality assessment of the systematic reviews revealed two studies of moderate risk of bias and five with high risk of bias. The two systematic reviews of moderate risk of bias stated divergent numbers needed to treat (NNT) to prevent one patient from implant failure. Four of the primary studies comparing antibiotic prophylaxis with placebo were estimated to be of low, or moderate, risk of bias and subjected to meta-analysis. The NNT was 50 (pooled RR 0.39, 95% CI 0.18, 0.84; P = 0.02). None of these four studies individually show a statistical significant benefit of antibiotic prophylaxis. Furthermore, narrative analysis of the studies eligible for meta-analysis reveals clinical heterogeneity regarding intervention and smoking. Antibiotic prophylaxis in conjunction with implant placement reduced the risk for implant loss by 2%. However, the sub-analysis of the primary studies suggests that there is no benefit of antibiotic prophylaxis in uncomplicated implant surgery in healthy patient. © 2015 John Wiley & Sons A/S.

2016-01-01

To prepare the registered nurse of tomorrow in the United Kingdom (UK) to care for patients in general practice (GP)-led services, today's student nurses need to have the opportunity to experience placements with practice nurses to enable them to make positive career choices to become practice nurses in the future. The role of the practice nurse is described in the article. As a pilot project, seventeen students undertook placements with practice nurses in one of seven GP practices selected by the London GP Deanery and the university as having fulfilled the criteria to support student nurses in placements. A mentorship preparation programme was provided to prepare practice nurses for mentoring these students. An evaluation study was undertaken of this pilot project. Findings showed that students were highly positive about the experience; the majority rated this placement as being as good as or better than previous placement experiences. The evaluation also explored the impact on student learning and the value that the placement had. There was a positive impact on students' knowledge and skills in certain clinical areas especially related to health promotion. Students also indicated that they would like to have additional placements with practice nurses and would consider a career as a practice nurse in the future. Copyright © 2015 Elsevier Ltd.

The secondary aim was searching for the genesis of product placement. The mentioned issues are explained from the perspectives of three groups: TV studios experts, directors and producers, and other experts (media agencies and advertisers. The Czech Republic market where product placement can be registered is very small – only few television companies. The survey was conducted during years 2011 and 2012 in the Czech Republic. There is no directly measurable tool to tell us exact outputs. However, the results reveal: Marketers are sure that product placement is efficient. The product placement belongs to a longterm marketing field where the brand building is also included. On the basis of the ascertainments acquired by the survey, the basic links between product placement, long-term marketing, and competitiveness are explained in this paper.

Residential aged care is an increasingly important health setting due to population ageing and the increase in age-related conditions, such as dementia. However, medical education has limited engagement with this fast-growing sector and undergraduate training remains primarily focussed on acute presentations in hospital settings. Additionally, concerns have been raised about the adequacy of dementia-related content in undergraduate medical curricula, while research has found mixed attitudes among students towards the care of older people. This study explores how medical students engage with the learning experiences accessible in clinical placements in residential aged care facilities (RACFs), particularly exposure to multiple comorbidity, cognitive impairment, and palliative care. Fifth-year medical students (N = 61) completed five-day clinical placements at two Australian aged care facilities in 2013 and 2014. The placements were supported by an iterative yet structured program and academic teaching staff to ensure appropriate educational experiences and oversight. Mixed methods data were collected before and after the clinical placement. Quantitative data included surveys of dementia knowledge and questions about attitudes to the aged care sector and working with older adults. Qualitative data were collected from focus group discussions concerning medical student expectations, learning opportunities, and challenges to engagement. Pre-placement surveys identified good dementia knowledge, but poor attitudes towards aged care and older adults. Negative placement experiences were associated with a struggle to discern case complexity and a perception of an aged care placement as an opportunity cost associated with reduced hospital training time. Irrespective of negative sentiment, post-placement survey data showed significant improvements in attitudes to working with older people and dementia knowledge. Positive student experiences were explained by in

Purpose Skeletal anchorage systems are increasingly used in orthodontics. This article describes the techniques of placement and removal of modified surgical miniplates used for temporary orthodontic anchorage and reports surgeons’ perceptions of their use. Patients and Methods We enrolled 97 consecutive orthodontic patients having miniplates placed as an adjunct to treatment. A total of 200 miniplates were placed by 9 oral surgeons. Patients and surgeons completed questionnaires after placement and removal surgeries. Results Fifteen miniplates needed to be removed prematurely. Antibiotics and anti-inflammatories were generally prescribed after placement but not after removal surgery. Most surgeries were performed with the patient under local anesthesia. Placement surgery lasted on average between 15 and 30 minutes per plate and was considered by the surgeons to be very easy to moderately easy. The surgery to remove the miniplates was considered easier and took less time. The patients’ chief complaint was swelling, lasting on average 5.3 ± 2.8 days after placement and 4.5 ± 2.6 days after removal. Conclusions Although miniplate placement/removal surgery requires the elevation of a flap, this was considered an easy and relatively short surgical procedure that can typically be performed with the patient under local anesthesia without complications, and it may be considered a safe and effective adjunct for orthodontic treatment.

Jones, M L; Akehurst, R

1999-07-01

The research outlined in this article was commissioned by the Sheffield and North Trent College of Nursing and Midwifery to explore the cost implications of pre-registration clinical placements in the context of Project 2000. The authors outline the methodology and findings of an exercise designed to collect relevant cost information which was not readily available. On the basis of these findings, they suggest that: at 1995/1996 pay and prices, clinical placements cost the education provider approximately pound 890 per student per annum; in terms of real resources, the value to service providers of the service contribution made by second- and third-year nursing and midwifery students on ward-based placements outweighs the value of the time spent by qualified staff on their supervision and education. Once the funding assumptions underlying the introduction of Project 2000 have been taken into account, second- and third-year nursing and midwifery students benefit the service provider by on average pound 3.46 for every hour they spend in an unrostered ward-based placement. The service contribution made by students in community-based clinical placements cannot free staff time in the same way as on the wards and, because qualified staff in these areas are generally more highly graded, the value of the time they spend on the supervision and education of students on placement is higher than in ward-based placements. Second- and third-year students therefore appear to cost the service provider on average pound 0.48 for each hour they spend in a community-based placement. It was not possible to determine whether this cost translates into a reduction in patient contacts.

Clinical placements are specifically designed to facilitate authentic learning opportunities and are an integral component of undergraduate nursing programs. However, as academics and clinicians frequently point out, clinical placements are fraught with problems that are long-standing and multidimensional in nature. Collaborative placement models, grounded in a tripartite relationship between students, university staff and clinical partners, and designed to foster students' sense of belonging, have recently been implemented to address many of the challenges associated with clinical placements. In this study a qualitative descriptive design was undertaken with the aim of exploring 14 third year third year nursing students' perceptions of a collaborative clinical placement model undertaken in an Australian university. Students participated in audio recorded focus groups following their final clinical placement. Thematic analysis of the interview data resulted in identification of six main themes: Convenience and Camaraderie, Familiarity and Confidence, Welcomed and Wanted, Belongingness and Support, Employment, and The Need for Broader Clinical Experiences. The clinical collaborative model fostered a sense of familiarity for many of the participants and this led to belongingness, acceptance, confidence and meaningful learning experiences.

Full Text Available Background. Whilst placement supervision and clinical education programmes are of significant value in shaping the behaviours of undergraduate healthcare students, appropriate provisions which are efficacious to the learner are somewhat lacking, particularly for students studying on UK MPharm programmes. Objectives. To explore and explain the value of placement supervision to the personal development and employability of undergraduate pharmacy students. Methods. Students participated in a week long community pharmacy pilot programme, a result of a collaborative effort between the School of Pharmacy and Life Sciences and a small consortium of community pharmacies. Students and stakeholders were asked to evaluate their experiences via separate questionnaires which had been developed to elicit views and attitudes. Key Findings. Feedback from students and stakeholders towards the experience was overwhelmingly positive with multiple benefits being reported. Of particular prominence was the emphasis in student feedback on the value of placement supervision to their professional and personal development. Findings were indicative of a development in clinical practice proficiencies, core skills, and improvement in decision-making practice. Conclusions. The benefits of clinical supervision to the professional and personal development of MPharm students are well documented, although attracting professional pharmacy supervisors is proving a problematic task for educational providers in the UK.

Full Text Available With competition becoming ever fiercer, brands must conform to modern marketing and become more influential on consumer perceptions by developing strategies according to the needs and demands of consumers. Hence it is very important to determine how the br and is perceived and placed in the consumer’s mind. Branding is a key issue on the modern agenda. As universities have understood the importance of establishing corporate identity and brand placement, they have joined the race and begun developing social strategies to develop their brand values. These include establishing brand belongingness, advertising and promotions and efforts to make the university stand out among similar ones. Brand placement in the minds of users is attempted through the name, logo , colors, characters and fonts representing the university used on clothing, office material and similar. Brand placement efforts include definitions by consumers of the product or service or attempts to distinguish these from those of competitors. This r esearch deals with a clothing b rand representing a university, brand image and product perceptions as well as the brand placement efforts. The scanning method was used in the research. The brand of casual clothing used as an example for brand placement as well as similarly known brands were examined for their product variety, prices and consumer portfolios. Measurement devices were prepared for the brand placement of the apparel designed and produced for the university, and a pilot trial was performed. I n the pilot trial, a set of questions was asked to a group of randomly chosen 242 people, consisting of academics, university students and administrative staff. The data obta ined were analyzed using SPSS 16 .0. Findings were given in tables according to sta tus variables. The finding of the research indicate that in brand placing efforts, for the intended consumer the apparel’s fabric, stitching and print/embroidery quality, its price

Chemical placement in heterogeneous and long reach horizontal wells

2006-03-15

The effective placement of chemical squeeze treatments in heterogeneous wells and long reach horizontal wells has proved a significant challenge, with various factors including heterogeneity, crossflow and pressure gradients between otherwise non-communicating zones within the well, all contributing to an uneven placement of the scale squeeze treatment into the reservoir. Current methods to circumvent these problems often rely on extremely expensive coiled tubing operations, staged diversion (temporary shut off) treatments or by designing treatments to deliberately overdose some zones in order to gain placement in other (e.g. low permeability) zones. Moreover for deepwater sub sea horizontal wells the costs associated with ''spot'' treating along the length of horizontal wells by coil tubing tractor operations can often be prohibitively expensive. For other very near well bore treatments such as acid stimulation a number of self diverting strategies including gelled acid treatments, staged viscoelastic surfactant treatments and foams have been applied in field treatments with some success. However the properties which make such treatments applicable for acid stimulation may also make them inappropriate for bullhead scale squeeze treatments. Recent work by the current authors has however indicated the possible benefits of using modified injection fluids to aid uniform scale inhibitor placement in such wells in order to effect more even placement. In summary this paper will describe the various options available for achieving self diversion and describes the potential drawbacks associated with the viscous placement fluids commonly used for acid simulation techniques. In addition, various simulation packages commonly used for scale related calculations are reviewed and their limitations, primarily due to the inherent assumptions made and input parameters used, for modelling squeeze treatments using such modified fluids are described.

Full Text Available The anterior maxilla presents a challenging milieu interior for ideal placement of implants because of the compromised bone quality. With the advent of intraoral bone harvesting and augmentation techniques, immediate implant placement into fresh extraction sockets have become more predictable. Immediate implant placement has numerous advantages compared to the delayed procedure including superior esthetic and functional outcomes, maintenance of soft and hard tissue integrity and increased patient compliance. This case report exhibits immediate implant placement in the maxillary esthetic zone by combining a minimal invasive autogenous block bone graft harvest technique for ensuring successful osseointegration of the implant at the extraction site.

The internet portal 'herzwegweiser.de' was developed to assist individuals with cardiovascular diseases in the phase III rehabilitation in the region of Berlin-Brandenburg. It provides information on this specific disease as well as on aftercare services, e. g. regional cardiac groups. For the medical and therapeutic colleagues specific information such as treatment guidelines and a cardiac group placement service for trainers and medical doctors were set up. The study was based on a mixed-methods design. Initially, structured interviews were conducted to identify the expectations and needs of the internet portal. After implementation of the portal, a partially standardized written survey was used to evaluate its acceptance and usability. 105 former rehab patients and 42 medical colleagues participated. The evaluation of the questionnaires was carried out with frequency distributions, mean comparisons and Chi-square tests. The site was rated with an overall high approval rating. Over 90% of the former rehab patients rated content, structure, design, and the search function of the portal positive as did more than 85% of the medical colleagues. 97% of the former rehab patients and 95% professionals would recommend 'herzwegweiser.de'. This internet portal can serve as a model for other regions and possibly other diseases. © Georg Thieme Verlag KG Stuttgart · New York.

At the Roots of Product Placement: The Mere Exposure Effect

Stefano Ruggieri

2013-05-01

Full Text Available The present study aims to analyze the effect of product placement on attitude change and takes into consideration psychological models of the mere exposure effect. A sample of high school students watched an excerpt from two widely-distributed movies in which several products were shown by using the technique known as product placement. The results indicate that students who saw the commercial brand liked the products more than those who didn’t see it. This effect, in line with the literature on the product placement effect, seems to be independent from the recognition of the brand in the movie excerpt. This study also shows that, in the high involvement condition, one exposure is enough to produce a positive attitude toward the brand.

Performance and impact of dynamic data placement in ATLAS

CERN Document Server

Maier, Thomas; The ATLAS collaboration

2018-01-01

For high-throughput computing the efficient use of distributed computing resources relies on an evenly distributed workload, which in turn requires wide availability of input data that is used in physics analysis. In ATLAS, the dynamic data placement agent C3PO was implemented in the ATLAS distributed data management system Rucio which identifies popular data and creates additional, transient replicas to make data more widely and more reliably available. This contribution presents studies on the performance of C3PO and the impact it has on throughput rates of distributed computing in ATLAS. This includes analysis of the placement algorithm selection behaviour regarding the data considered for replication and destination storage elements, usage after the placement decision of the chosen datasets in general and the newly created copies in particular, and the impact on metrics like job waiting times, task completion times and failure rates of tasks.

Student engagement in interprofessional working in practice placement settings.

. To investigate the nature of student engagement in interprofessional interaction while on placement. Due to continuing emphasis on improving interprofessional collaboration, UK educational establishments are required to offer pre-qualifying health and social care students interprofessional education in order that they acquire relevant competencies. However, few formal interprofessional education initiatives occur in practice settings and little is known about pre-qualifying students' non-formal learning about interprofessional issues while on placement. From 2003-2005 an English Faculty of Health and Social Care conducted a qualitative study to explore opportunities for interprofessional learning and working available to students in practice placement settings. Case studies were conducted in a coronary care ward, a medical ward for older patients, a maternity unit, a paediatric unit, an integrated community learning disabilities team and a residential facility for adults with challenging behaviour. Gaining access was complex, due to variable student timetables and UK research governance requirements. Sites were therefore selected according to geographical area and timing of student placements. Details of interprofessional interaction (formal and informal) were observed and recorded. Interviews were conducted with a convenience sample of 20 practitioners and 15 students. Data were analysed thematically. Student experience varied considerably. Contributing factors included the influence of doctors and differing professional cultures; mentors' support for student engagement in interprofessional working; and individual students' confidence levels. Most sites were managed by nurses and some senior nurses were proactive in involving students interprofessionally. However, many students lacked systematic support for interprofessional engagement. Students lack parity of experience concerning interprofessional activity on placement. Where they do not have systematic

In order to achieve esthetically more satisfying results, it has been proposed to place ITI implants with their border between the rough and smooth surfaces below the level of the alveolar crest, thereby obtaining a submucosally located implant shoulder following healing. The aim of the present experimental study was to clinically and radiographically evaluate the tissue response to the placement of one-stage transmucosal implants with the border between the rough and the smooth surfaces sunk by 1 mm into a subcrestal location. 11 patients underwent comprehensive dental care including the placement of 2 implants of the ITI Dental Implant System in the same quadrant (test and control). Randomly assigned control implants were placed according to the manufacturer's instructions, i.e. the border between the rough titanium plasma-sprayed and the smooth polished surfaces precisely at the alveolar crest. At the test implant the apical border of the polished surface was placed approximately 1 mm below the alveolar crest. Probing bone levels were assessed at implant placement (baseline), 4 and 12 months later. Modified plaque and modified gingival indices were recorded at 1, 2, 3, 4 and 12 months. Clinical probing depth and "attachment" levels were measured at 4 and 12 months. All parameters were assessed at 6 sites around each implant. The mean for each implant was calculated and used for analysis. The Wilcoxon matched pairs signed rank test and the Student t-test were applied to detect differences over time and between the test and control implants. At baseline, a mean difference in probing bone level of -0.86 mm (SD 0.43 mm, p placed more deeply. Both test and control implants lost a significant amount of clinical bone height during the first 4 months (test 1.16 mm, p placed under standard conditions, the bone adjacent to the polished surface of more deeply placed ITI implants is also lost over time. From a biological point of view, the placement of the border between

Williams, Christopher; Costa, Joseph; Mandia, Stephen; Henderson, Randal; Marino, Robert; Mendenhall, Nancy

2012-05-01

Surgical absence of the prostate can make placement of fiducial markers difficult, because anatomic landmarks are distorted and there is a paucity of substantial tissue to hold fast the markers. We describe a method for improving the accuracy of fiducial marker placement for the purpose of salvage or adjuvant external beam radiation therapy for prostate cancer in patients who have undergone radical prostatectomy. To assist with identification of the urethrovesical junction and to facilitate placement of the markers, a Foley catheter was placed and the balloon was inflated. Gentle traction on the catheter seated the balloon at the bladder neck to echographically define the anatomy of the urethrovesical junction. Next, a rectal ultrasound probe was inserted into the rectum, allowing visualization of the region of the urethrovesical junction. Fiducial markers were then placed bilaterally in the detrusor muscle at the bladder neck or in the periurethral tissue using the applicator needle. The treating radiation oncologist verified that marker placement was suitable for assisting with radiation therapy in all cases. Preradiation pelvic imaging verified that markers were not in the bladder or urethral lumen, and there were no patient complaints of voiding out the markers with urination.

International clinical placements for Australian undergraduate nursing students: A systematic thematic synthesis of the literature.

2015-10-01

International clinical placements provide undergraduate nursing students with the opportunity to experience or practice nursing care in diverse countries, settings, and cultures. This systematic review aims to ascertain the current knowledge on international clinical placements offered by undergraduate nursing programs in Australia. It seeks to explore three questions: (1) How have previous experiences of nursing students' international clinical placements been described? (2) How have participants and stakeholders determined if the placement has been successful? And (3) What benefits or challenges have been identified by stakeholders as a result of participating in international clinical placements? A systematic thematic synthesis was undertaken. A search of electronic databases including CINAHL, Proquest Central, Scopus, PubMed, and Health Collection was undertaken between September and October 2014. Key terms including 'international clinical placement', 'study abroad', 'international exchange', 'nursing', and 'Australia' were used to identify articles that appeared in peer-reviewed English language journals and that explored international clinical placements offered to undergraduate nursing students by Australian universities. Eight studies were identified that meet the inclusion criteria, and through thematic analysis, five key themes were identified including developing cultural awareness and competence, providing a global perspective on health care, translation of theory to practice, growing personally through reflection, and overcoming apprehension to successfully meet the challenge. A comparison search of literature from Canada and the United Kingdom revealed that similar themes occurred internationally. Although personal successes were identified by students undertaking international clinical placement, further research is required to identify all stakeholder experiences including those of the educators, the educational institutions, and travel providers

To assess the effectiveness and complication rate with Essure microinsert placements for tubal sterilization and the concomitant bipolar intrauterine surgical procedure. Case control study. Department of gynecology and obstetrics of a general hospital in France. 382 women, including 41 undergoing one or several concomitant uterine procedures with Essure placement, and 341 undergoing Essure placement only (controls). Essure placement with or without bipolar hysteroscopic procedure for polyp, myoma, or endometrial ablation. Success rate for microinsert placement and complications at 3 months. Forty-one patients had Essure microinserts placed in combination with a bipolar hysteroscopic procedure: endometrial resection (n=32), fibroma resection (n=4), or polyp ablation (n=5). They were compared with 341 patients who underwent Essure placement only. The success rate for Essure placement was 97.6% in the combination group versus 97.6% in the control group. The complication rate was 4.9% (n=2) in the combination group versus 2.6% (n=9) in the control group. The difference in the success and complication rates was not statistically significant. Performing intrauterine bipolar resection during hysteroscopy for sterilization is possible without reducing the Essure placement success rate and without increasing morbidity.

Full Text Available Background: Airway obstruction or tracheoesophageal fistula (TEF near the tracheal carina requires placement of Y-shaped stents. Herein, we describe our multicenter experience with the placement of Dumon silicone Y-stents. We also conduct a systematic review for studies describing the deployment of airway silicone Y-stents. Methods: This was a retrospective analysis of consecutive subjects who underwent placement of silicone Y-stents. The clinical details including the underlying diagnosis, indication for the placement of silicone Y-stents, success of stent placement, and follow-up are presented. The PubMed and EMBASE databases were also reviewed for studies describing the placement of silicone Y-stents. Results: During the study, 27 silicone Y-stents were placed. The mean (standard deviation age of the study population (85.2% males was 57.7 (13.5 years. The stents were placed for airway obstruction in 77.8% and TEF in 29.6% of the patients. The most common underlying disease was carcinoma of the esophagus. The degree of airway obstruction was grade 3–4 in 18 subjects, and respiratory failure was encountered in 18 subjects. The stent was deployed successfully in all the subjects. No deaths were encountered during stent placement. Most subjects had rapid relief of symptoms following the procedure. Excessive secretions and mucostasis were the most common stent-related complications followed by the development of granulation tissue. The systematic review yielded nine studies (338 subjects with airway obstruction and/or TEF. The most common indication for silicone Y-stent placement was tracheobronchial obstruction and TEF due to malignancy. Benign disorders that necessitated stent placement included postintubation tracheal stenosis, airway malacia, and others. The stent was successfully placed in 98% with only one periprocedural death. Granulation tissue formation and mucostasis were the most common stent-related complications. Conclusion

The way people who experience mental illness are perceived by health care professionals, which often includes stigmatising attitudes, can have a significant impact on treatment outcomes and on their quality of life. To determine whether stigma towards people with mental illness varied for undergraduate nursing students who attended a non-traditional clinical placement called Recovery Camp compared to students who attended a 'typical' mental health clinical placement. Quasi-experimental. Seventy-nine third-year nursing students were surveyed; n=40 attended Recovery Camp (intervention), n=39 (comparison group) attended a 'typical' mental health clinical placement. All students completed the Social Distance Scale (SDS) pre- and post-placement and at three-month follow-up. Data analysis consisted of a one-way repeated measures analysis of variance (ANOVA) exploring parameter estimates between group scores across three time points. Two secondary repeated measures ANOVAs were performed to demonstrate the differences in SDS scores for each group across time. Pairwise comparisons demonstrated the differences between time intervals. A statistically significant difference in ratings of stigma between the intervention group and the comparison group existed. Parameter estimates revealed that stigma ratings for the intervention group were significantly reduced post-placement and remained consistently low at three-month follow-up. There was no significant difference in ratings of stigma for the comparison group over time. Students who attended Recovery Camp reported significant decreases in stigma towards people with a mental illness over time, compared to the typical placement group. Findings suggest that a therapeutic recreation based clinical placement was more successful in reducing stigma regarding mental illness in undergraduate nursing students compared to those who attended typical mental health clinical placements.

A virtual reality based simulator for learning nasogastric tube placement.

Science.gov (United States)

Choi, Kup-Sze; He, Xuejian; Chiang, Vico Chung-Lim; Deng, Zhaohong

2015-02-01

Nasogastric tube (NGT) placement is a common clinical procedure where a plastic tube is inserted into the stomach through the nostril for feeding or drainage. However, the placement is a blind process in which the tube may be mistakenly inserted into other locations, leading to unexpected complications or fatal incidents. The placement techniques are conventionally acquired by practising on unrealistic rubber mannequins or on humans. In this paper, a virtual reality based training simulation system is proposed to facilitate the training of NGT placement. It focuses on the simulation of tube insertion and the rendering of the feedback forces with a haptic device. A hybrid force model is developed to compute the forces analytically or numerically under different conditions, including the situations when the patient is swallowing or when the tube is buckled at the nostril. To ensure real-time interactive simulations, an offline simulation approach is adopted to obtain the relationship between the insertion depth and insertion force using a non-linear finite element method. The offline dataset is then used to generate real-time feedback forces by interpolation. The virtual training process is logged quantitatively with metrics that can be used for assessing objective performance and tracking progress. The system has been evaluated by nursing professionals. They found that the haptic feeling produced by the simulated forces is similar to their experience during real NGT insertion. The proposed system provides a new educational tool to enhance conventional training in NGT placement. Copyright © 2014 Elsevier Ltd. All rights reserved.

The workplace provides veterinary students with opportunities to develop a range of skills, making workplace learning an important part of veterinary education in many countries. Good preparation for work placements is vital to maximize learning; to this end, our group has developed a series of three computer-aided learning (CAL) packages to support students. The third of this series is the Animal Management and Husbandry Online Placement Tool (AMH OPT). Students need a sound knowledge of animal husbandry and the ability to handle the common domestic species. However, teaching these skills at university is not always practical and requires considerable resources. In the UK, the Royal College of Veterinary Surgeons (RCVS) requires students to complete 12 weeks of pre-clinical animal management and husbandry work placements or extramural studies (EMS). The aims are for students to improve their animal handling skills and awareness of husbandry systems, develop communication skills, and understand their future clients' needs. The AMH OPT is divided into several sections: Preparation, What to Expect, Working with People, Professionalism, Tips, and Frequently Asked Questions. Three stakeholder groups (university EMS coordinators, placement providers, and students) were consulted initially to guide the content and design and later to evaluate previews. Feedback from stakeholders was used in an iterative design process, resulting in a program that aims to facilitate student preparation, optimize the learning opportunities, and improve the experience for both students and placement providers. The CAL is available online and is open-access worldwide to support students during veterinary school.

Forrest Cummings

2014-01-01

Full Text Available Enteral feeding tube placement has been described in veterinary medicine for several years. Indications include oral, esophageal, gastrointestinal, pancreatic, hepatic, and neurologic diseases. In this paper, endoscopically assisted placement of an esophagojejunostomy (EJ feeding tube in dogs with pancreatitis and prolonged anorexia is described. To the author’s knowledge there are no published reports of this procedure. Esophagojejunostomy feeding tubes provide an alternative to other forms of postgastric feeding tube placement (e.g., nasojejunal, gastrojejunostomy, and jejunostomy tubes without the associated complications of patient discomfort, sneezing, epistaxis, and peritonitis. Tube occlusion, transient vomiting and loose stool were the most commonly reported complications.

2011-01-01

Full Text Available Pole placement problems are especially important for disturbance rejection and stabilization of dynamical systems and regarded as algebraic inverse eigenvalue problems. In this paper, we propose gain formulae of state feedback through PID-elements to achieve desired pole placement for a delay-free LTI system with single input. Real and complex stable poles can be assigned with the proposed compact gain formulae. Numerical examples show that our proposed gain formulae can be used effectively resulting in very satisfactory responses.

Lin, Jian-Fu; Xu, You-Lin; Law, Siu-Seong

2018-05-01

A structural damage detection-oriented multi-type sensor placement method with multi-objective optimization is developed in this study. The multi-type response covariance sensitivity-based damage detection method is first introduced. Two objective functions for optimal sensor placement are then introduced in terms of the response covariance sensitivity and the response independence. The multi-objective optimization problem is formed by using the two objective functions, and the non-dominated sorting genetic algorithm (NSGA)-II is adopted to find the solution for the optimal multi-type sensor placement to achieve the best structural damage detection. The proposed method is finally applied to a nine-bay three-dimensional frame structure. Numerical results show that the optimal multi-type sensor placement determined by the proposed method can avoid redundant sensors and provide satisfactory results for structural damage detection. The restriction on the number of each type of sensors in the optimization can reduce the searching space in the optimization to make the proposed method more effective. Moreover, how to select a most optimal sensor placement from the Pareto solutions via the utility function and the knee point method is demonstrated in the case study.

Heuristic Data Placement for Data-Intensive Applications in Heterogeneous Cloud

Directory of Open Access Journals (Sweden)

Qing Zhao

2016-01-01

Full Text Available Data placement is an important issue which aims at reducing the cost of internode data transfers in cloud especially for data-intensive applications, in order to improve the performance of the entire cloud system. This paper proposes an improved data placement algorithm for heterogeneous cloud environments. In the initialization phase, a data clustering algorithm based on data dependency clustering and recursive partitioning has been presented, and both the factor of data size and fixed position are incorporated. And then a heuristic tree-to-tree data placement strategy is advanced in order to make frequent data movements occur on high-bandwidth channels. Simulation results show that, compared with two classical strategies, this strategy can effectively reduce the amount of data transmission and its time consumption during execution.

Full Text Available ABSTRACT Purpose We present a novel AUS implantation technique using a single perineal incision for single device placement or in combination with an inflatable penile prosthesis (IPP. Urinary and sexual dysfunction following the management of prostate cancer has a significant impact on the quality of life of our patients. While there are marginal changes in the prosthetic devices, we strive to reduce post-operative morbidity while maximizing efficacy. Materials and Methods We retrospectively reviewed the outcomes of 6 patients who underwent single perineal incision placement of a virgin AUS in 2014, 3 with simultaneous IPP placement. In all cases, the pressure regulating balloons (PRB were placed in a high sub-muscular ectopic position and the pumps were placed into a sub-dartos pouch through the perineal incision, which was also validated using a cadaveric model. Results The mean patient age was 61 (SD, 7.5 years with mean body mass index of 31 (SD, 5.9. The average pre-operative pad usage was 7.7 (SD 1.63 pads per day. The mean follow-up was 13.9 months (SD 9.45. Four out of the six patients reported utilizing ≤1 pad daily at follow-up. The one patient who was not initially dry required downsizing of his cuff to 3.5cm; the remaining patient was lost to follow-up. There were no identifiable perioperative or post-operative complications. Conclusions We present our initial report of using a single perineal incision for AUS implantation with a validated sub-dartos pump location, which is safe and effective for implantation of an AUS as a single or double implantation in well-selected patients.

To report two cases of pregnancy after placement of Essure micro-inserts. Case report. University-based Department of Obstetrics and Gynecology. Patient 1, a 38-year-old woman, presented with a positive pregnancy test 7 months after Essure hysteroscopic sterilization. Patient 2, a 35-year-old female, became pregnant approximately 1 year after undergoing the Essure procedure. Patient 1 received obstetric ultrasounds, a prophylactic cerclage, a cesarean section, and a tubal ligation. Patient 2 underwent a postprocedure hysterosalpingogram, an obstetric ultrasound, pregnancy termination, diagnostic pelvic ultrasound, and a hysterectomy. Documentation of normal progress of pregnancy after Essure placement. Patient 1 carried an uncomplicated pregnancy to term with an Essure micro-insert in place. Patient 2 became pregnant despite an hysterosalpingogram showing tubal occlusion and was ultimately found to have a micro-insert perforating the uterine wall. The presence of Essure micro-inserts in the fallopian tubes do not appear to interfere with implantation and pregnancy. Uterine perforation by an Essure micro-insert in proximity to the tubal ostia may mimic proper micro-insert placement and bilateral tubal occlusion on both hysterosalpingogram and saline infusion sonography.

Pratt, Jeffrey C; Hirshberg, Alan J

2005-01-01

To evaluate the effectiveness of an intubation-training module and special-waiver project in which Emergency Medical Technician (EMT)-Basics were trained to perform endotracheal intubations in a rural community. This was a prospective observational study over a four-year period (July 1998 through May 2002) of all intubation attempts by EMT-Basics in the field. The authors observed intubation data, training methods, and quality-assurance methods of a special-waiver project agreed to by the State Department of Public Health to train and allow EMT-Basics to intubate patients. Data were from documentation unique to the project. Project documentation evaluated the placement and complication(s) of endotracheal tube (ETT) placement after arrival to the emergency department. An intubation attempt was defined as direct laryngoscopy. A successful attempt was defined as an appropriately sized ETT placed and secured in the trachea below the vocal cords and above the carina. Confirmation of placement in the field included accepted clinical methods and the use of qualitative colorimetric end-tidal carbon dioxide detectors. The EMT-Basics were trained using a paramedic curriculum, including operating room intubations on live adult patients. All patients were in either cardiopulmonary or respiratory arrest. Thirty-two intubations were performed by EMT-Basics. Thirty attempts were successful and two were unsuccessful (94%; 95% confidence interval [CI] 80-98%). Unsuccessful ETT placements were managed with accepted basic life support airway standards. There were no unrecognized esophageal ETT placements (0%; 95% CI 0-11%). This study demonstrated that with an intensive training program using selected highly motivated providers and close monitoring, a program of EMT-Basic ETT placement in a rural setting can achieve acceptable success rates in patients in cardiac or respiratory arrest.

PurposeTo evaluate the intermediate outcomes of temporary partially covered tracheobronchial stenting in patients with benign tracheobronchial stenosis.Materials and MethodsWe conducted a retrospective study of patients with benign tracheobronchial stenosis who underwent stent placement. All stents were removed approximately 3 months after placement. Respiratory function was assessed using the visual analogue scale (VAS) and Karnofsky performance status scale (KPS) before and after stent placement. The lumen diameters of the stenotic lesions were measured using chest computed tomography (CT) and compared between before stent placement and after stent removal.ResultsA total of 51 stents were successfully placed in consecutive 51 patients with benign tracheobronchial stenosis. No serious complications occurred. The mean VAS and KPS scores significantly improved after stent removal (6.291 ± 0.495 and 25.352 ± 10.533, respectively) compared with those before stent placement (1.493 ± 0.504 and 60.140 ± 16.344, respectively; P < 0.05). The mean lumen transverse diameters of the stenotic site in trachea and main bronchus after stent removal (17.235 ± 3.457 and 8.993 ± 0.961 mm; 1 month post-removal; 16.353 ± 4.132 and 8.357 ± 1.082 mm; 6 months post-removal) were significantly larger than those before stent placement (7.876 ± 2.351 and 2.143 ± 0.770 mm, respectively; P < 0.05). However, the mean lumen diameters between 1 and 6 months after stent removal had no significant difference (P > 0.05).ConclusionTemporary partially covered stenting may be a safe and effective treatment for benign tracheobronchial stenosis.

Iwai, Toshinori; Mitsudo, Kenji; Fukui, Takafumi

2008-01-01

Superselective intra-arterial chemotherapy via the superficial temporal artery (STA) has become useful for oral cancer. However, this method can not be performed if catheter placement via the STA is impossible. Therefore, we report a surgical method for catheter placement via the occipital artery (OA) to achieve retrograde superselective intra-arterial chemotherapy. Preoperatively, three-dimensional computed tomography angiography was performed to identify the course of the external carotid artery and the relationship between OA and the target artery. Ten patients with oral cancer underwent catheter placement via the OA with Doppler ultrasound and Harmonic Scalpel under local anesthesia. Catheter placement via the OA was superselectively successful in all the patients. The mean exposure time of OA and mean operating time were 17.5 min and 70.5 min, respectively. Catheter placement via the OA is useful when catheter placement via the STA is impossible. Three-dimensional vascular mapping and the use of Doppler ultrasound and Harmonic Scalpel can shorten the surgical time. (author)

Consumer on-line behaviors are more important than ever due to highly growth of on-line shopping. The purposes of this study were to design placement methods of background music for shopping website and examine the effect on browsers' emotional and cognitive response. Three placement points of background music during the browsing, i.e. 2 min., 4 min., and 6 min. from the start of browsing were considered for entry points. Both browsing without music (no music) and browsing with constant music volume (full music) were treated as control groups. Participants' emotional state, approach-avoidance behavior intention, and action to adjust music volume were collected. Results showed that participants had a higher level of pleasure, arousal and approach behavior intention for the three placement points than for no music and full music. Most of the participants for full music (5/6) adjusted the background music. Only 16.7% (3/18) participants for other levels turn off the background music. The results indicate that playing background music after the start of browsing is benefit for on-line shopping atmosphere. It is inappropriate to place background music at the start of browsing shopping website. The marketer must manipulated placement methods of background music for a web store carefully.

Neurosciences critical care units (NCCUs) present a unique opportunity to junior trainees in neurosurgery as well as foundation trainees looking to gain experience in the management of critically ill patients with neurological conditions. Placements in NCCUs are undertaken in the early years of neurosurgical training or during neurosciences themed foundation programmes. We sought to quantify the educational benefits of such placements from the trainee perspective. Thirty-two trainees who had undertaken placements at Foundation Year 2 (FY2) to Specialty Trainee Year 3 (ST3) level between August 2009 and April 2013 were invited to take part in an online questionnaire survey. Competence in individual skills was self-rated on a ranked scale from one (never observed) to five (performed unsupervised) both before and after the placement. Trainees were also asked a series of questions pertaining to their ability to manage common neurosurgical conditions, as well as the perceived educational rigour of their placement. Twenty-three responses were received. Eighteen responses were from FY2s and seven were from ST1-3 level trainees. Following their placements, 100% of respondents felt better equipped to deal with neurosurgical and neurological emergencies and cranial trauma. Most felt better equipped to manage hydrocephalus (95.7%), polytrauma patients (95.7%), spontaneous intracranial haemorrhage (91.3%) and spinal trauma (82.6%). Significant increases were seen in experience in all practical skills assessed. These included central venous catheterisation (p training programme as well as in the Foundation Programme. This supports the incorporation of a four- to six-month NCCU rotation in early years training as educationally valuable.

Perceived Impacts of a Public Health Training Center Field Placement Program Among Trainees

Full Text Available There is heightened interest in identifying the impact of the federally-funded Public Health Training Center (PHTC program. Although evaluation studies have been conducted of public health training in general, evaluations of PHTC programs are rare. Field placement components are Congressionally-mandated requirements of PHTCs. Field placements are typically intensive, supervised externships for students to gain public health experience with local health departments or non-profit organizations. We have found no published evaluations of PHTC field placement components. This may be because of their small size and unique nature. We designed and evaluated a 200-hour field placement program at an established Public Health Training Center. The evaluation included pre/post surveys measuring public health core competencies, and post-experience interviews. We found significant increases in three competency domains among trainees: policy development and program planning, communication skills, and community dimensions of practice. These outcomes contribute to an evidence base on the efficacy of PHTC field placement programs, and underscore their role in public health training.

Common ECG Lead Placement Errors. Part I: Limb Lead Reversals

Allison V. Rosen

2015-10-01

Full Text Available Background: Electrocardiography (ECG is a very useful diagnostic tool. However, errors in placement of ECG leads can create artifacts, mimic pathologies, and hinder proper ECG interpretation. It is important for members of the health care team to be able to recognize the common patterns resulting from lead placement errors. Methods: 12-lead ECGs were recorded in a single male healthy subject in his mid 20s. Six different limb lead reversals were compared to ECG recordings from correct lead placement. Results: Classic ECG patterns were observed when leads were reversed. Methods of discriminating these ECG patterns from true pathologic findings were described. Conclusion: Correct recording and interpretation of ECGs is key to providing optimal patient care. It is therefore crucial to be able to recognize common ECG patterns that are indicative of lead reversals.

The Kinect v2 sensor may be a cheap and easy to use sensor to quantify gait in clinical settings, especially when applied in set-ups integrating multiple Kinect sensors to increase the measurement volume. Reliable estimates of foot placement locations are required to quantify spatial gait parameters. This study aimed to systematically evaluate the effects of distance from the sensor, side and step length on estimates of foot placement locations based on Kinect's ankle body points. Subjects (n = 12) performed stepping trials at imposed foot placement locations distanced 2 m or 3 m from the Kinect sensor (distance), for left and right foot placement locations (side), and for five imposed step lengths. Body points' time series of the lower extremities were recorded with a Kinect v2 sensor, placed frontoparallelly on the left side, and a gold-standard motion-registration system. Foot placement locations, step lengths, and stepping accuracies were compared between systems using repeated-measures ANOVAs, agreement statistics and two one-sided t -tests to test equivalence. For the right side at the 2 m distance from the sensor we found significant between-systems differences in foot placement locations and step lengths, and evidence for nonequivalence. This distance by side effect was likely caused by differences in body orientation relative to the Kinect sensor. It can be reduced by using Kinect's higher-dimensional depth data to estimate foot placement locations directly from the foot's point cloud and/or by using smaller inter-sensor distances in the case of a multi-Kinect v2 set-up to estimate foot placement locations at greater distances from the sensor.

To explore students' opinions of the learning environment during clinical placement in settings outside traditional hospital settings. Clinical placement experiences may influence positively on nursing students attitudes towards the clinical setting in question. Most studies exploring the quality of clinical placements have targeted students' experience in hospital settings. The number of studies exploring students' experiences of the learning environment in healthcare settings outside of the hospital venue does not match the growing importance of such settings in the delivery of health care, nor the growing number of nurses needed in these venues. A survey design was used. The Clinical Learning Environment Inventory was administered to two cohorts of undergraduate nursing students (n = 184) after clinical placement in mental health care, home care and nursing home care. Nursing students' overall contentment with the learning environment was quite similar across all three placement areas. Students in mental health care had significantly higher scores on the subscale individualisation, and older students had significantly higher scores on the total scale. Compared with other studies where the Clinical Learning Environment Inventory has been used, the students' total scores in this study are similar or higher than scores in studies including students from hospital settings. Results from this study negate the negative views on clinical placements outside the hospital setting, especially those related to placements in nursing homes and mental healthcare settings. Students' experience of the learning environment during placements in mental health care, home care and nursing homes indicates the relevance of clinical education in settings outside the hospital setting. © 2014 The Authors.

Lee, Tzu-Hsien

2018-01-01

Pushing and pulling tasks are very common in daily and industrial workplaces. They are one major source of musculoskeletal complaints. This study aimed to examine the foot placement strategy while pushing and pulling. Thirteen young males and ten young females were recruited as participants. A two (pushing and pulling) by four (48 cm, 84 cm, 120 cm, and 156 cm) factorial design was used. Exertion direction and exertion height significantly affected foot placement strategy. Pushing task needed more anteroposterior space than pulling task. The percentages of female/male for trailing foot position ranged from 77% to 90% (pushing) and from 80% to 93% (pulling) across the exertion heights. Practitioners should provide an anteroposterior space approximately to 70% body stature for workers to exert their maximum pulling and pushing strengths.

Previous PICC Placement May Be Associated With Catheter-Related Infections in Hemodialysis Patients

International Nuclear Information System (INIS)

Butler, Philip J.; Sood, Shreya; Mojibian, Hamid; Tal, Michael G.

2011-01-01

Background: Catheter-related infections (CRIs) are a significant source of morbidity and mortality in hemodialysis patients. The identification of novel, modifiable risk factors for CRIs may lead to improved outcomes in this population. Peripherally inserted central catheters (PICCs) have been hypothesized to compromise vascular access due to vascular damage and venous thrombosis, whereas venous thrombosis has been linked to the development of CRIs. Here we examine the association between PICC placement and CRIs. Methods: A retrospective review was performed of all chronic hemodialysis catheter placements and exchanges performed at a large university hospital from September 2003 to September 2008. History of PICC line use was determined by examining hospital radiologic records from December 1993 to September 2008. Catheter-related complications were assessed and correlated with PICC line history. Results: One hundred eighty-five patients with 713 chronic tunneled hemodialysis catheter placements were identified. Thirty-eight of those patients (20.5%) had a history of PICC placement; these patients were more likely to have CRIs (odds ratio = 2.46, 95% confidence interval = 1.71–3.53, p < .001) compared with patients without a history of PICC placement. There was no difference between the two groups in age or number of catheters placed. Conclusion: Previous PICC placement may be associated with catheter-related infections in hemodialysis patients.

Well described complications of SEMS placement include tumor growth, obstruction, and stent migration. SEMS occlusions are treated by SEMS redeployment, argon plasma coagulation application, balloon dilation, and surgical bypass. At our center, we usually place the second SEMS into the first SEMS if there is complete occlusion by the tumor. We discovered a...

Parallel algorithms for placement and routing in VLSI design. Ph.D. Thesis

Science.gov (United States)

Brouwer, Randall Jay

1991-01-01

The computational requirements for high quality synthesis, analysis, and verification of very large scale integration (VLSI) designs have rapidly increased with the fast growing complexity of these designs. Research in the past has focused on the development of heuristic algorithms, special purpose hardware accelerators, or parallel algorithms for the numerous design tasks to decrease the time required for solution. Two new parallel algorithms are proposed for two VLSI synthesis tasks, standard cell placement and global routing. The first algorithm, a parallel algorithm for global routing, uses hierarchical techniques to decompose the routing problem into independent routing subproblems that are solved in parallel. Results are then presented which compare the routing quality to the results of other published global routers and which evaluate the speedups attained. The second algorithm, a parallel algorithm for cell placement and global routing, hierarchically integrates a quadrisection placement algorithm, a bisection placement algorithm, and the previous global routing algorithm. Unique partitioning techniques are used to decompose the various stages of the algorithm into independent tasks which can be evaluated in parallel. Finally, results are presented which evaluate the various algorithm alternatives and compare the algorithm performance to other placement programs. Measurements are presented on the parallel speedups available.

Purpose. To compare the differences in practice and outcome of all radiologically and surgically placed central venous catheters retrospectively over a 2-year period simultaneously, at a single institution. Methods.A total of 253 Hickman catheters were inserted in 209 patients; 120 were placed radiologically in 102 patients and 133 were placed surgically in 107 patients. The indication was chemotherapy in 76% of radiological and in 47% of surgical cases; the remainder were for total parenteral nutrition and venous access. Results. There were 6 (4.5%) primary surgical failures and a further 17 (13%) surgical cases requiring multiple placement attempts. Pneumothorax occurred once (0.8%) surgically and four times (3.3%) radiologically. There were no radiological primary misplacements but there were five (3.7%) surgical ones. Catheter or central vein thrombosis occurred in four (3.3%) radiological and five (3.7%) surgical cases. The rate of infection per 1000 catheter-days was 1.9 in radiologically placed catheters and 4.0 in surgically placed ones (p<0.001). Average catheter life-span was similar for the two placement methods (100±23 days). Conclusion. Radiological placement is consistently more reliable than surgical placement. There are fewer placement complications and fewer catheter infections overall

Optimized Virtual Machine Placement with Traffic-Aware Balancing in Data Center Networks

Tao Chen

2016-01-01

Full Text Available Virtualization has been an efficient method to fully utilize computing resources such as servers. The way of placing virtual machines (VMs among a large pool of servers greatly affects the performance of data center networks (DCNs. As network resources have become a main bottleneck of the performance of DCNs, we concentrate on VM placement with Traffic-Aware Balancing to evenly utilize the links in DCNs. In this paper, we first proposed a Virtual Machine Placement Problem with Traffic-Aware Balancing (VMPPTB and then proved it to be NP-hard and designed a Longest Processing Time Based Placement algorithm (LPTBP algorithm to solve it. To take advantage of the communication locality, we proposed Locality-Aware Virtual Machine Placement Problem with Traffic-Aware Balancing (LVMPPTB, which is a multiobjective optimization problem of simultaneously minimizing the maximum number of VM partitions of requests and minimizing the maximum bandwidth occupancy on uplinks of Top of Rack (ToR switches. We also proved it to be NP-hard and designed a heuristic algorithm (Least-Load First Based Placement algorithm, LLBP algorithm to solve it. Through extensive simulations, the proposed heuristic algorithm is proven to significantly balance the bandwidth occupancy on uplinks of ToR switches, while keeping the number of VM partitions of each request small enough.

Some universities are looking to provide a more diverse range of clinical learning experiences through extended clinical placement programs. This approach will potentially have a significant impact on practitioners. The aim of this study was to conduct a national survey of optometrists to ascertain their perspectives on participating in extended clinical placement programs. Members of Optometry Australia were invited to participate in a survey conducted during June and July 2014. A total of 268 practitioners participated (six per cent of registered Australian optometrists): 159 were predominantly employees or locums and 109 were owners or managers who identified as the key representative of a practice or organisation for the purpose of this survey. Almost two-thirds (65 per cent) of participants, who were employees or locums were supportive of extended clinical placement programs. Among this group, females were more likely to be supportive than males (p = 0.033). In comparison, just over one-third (34 per cent) of participants who were key decision-makers were supportive, with 30 per cent possibly supportive and 36 per cent not supportive. Among key decision-makers, males were more likely to be supportive (p = 0.009). The top three perceived advantages of supervising a student were: opportunity to mentor early career development, opportunity to give back to the profession and future recruitment. The top three perceived disadvantages were: burden on time, decrease in number of patients examined and burden on support staff. Suggested incentives for supervising students were credit for continuing professional development and financial remuneration. There appears to be moderate support for extended clinical placement programs; however, there are incentives that might engage a larger proportion of the profession in the future. These findings can inform the development of effective and sustainable clinical training programs for optometry students. Additionally

Systematic evaluations of clinical placements are rare, especially when offered alongside academic postgraduate courses. An evidence-based approach is important to allow pedagogically-driven provision, rather than that solely governed by opinion or market demand. Our evaluation assessed a voluntary clinical placement scheme allied to a mental health course. Data were collected over academic years 2010/11- 2013/14, from participating students (n = 20 to 58) and clinician supervisors (n = 10-12), using a mixed-methods cross-sectional design. Quantitative evaluation captured information on uptake, dropout, resource use, attitudes and experience, using standardized (the Placement Evaluation Questionnaire; the Scale To Assess the Therapeutic Relationship - Clinical version and the University of Toronto Placement Supervisor Evaluation) and bespoke questionnaires and audit data. Qualitative evaluation comprised two focus groups (5 clinicians, 5 students), to investigate attitudes, experience, perceived benefits, disadvantages and desired future developments. Data were analysed using framework analysis to identify a priori and emergent themes. High uptake (around 70 placements per annum), low dropout (2-3 students per annum; 5 %) and positive focus group comments suggested placements successfully provided added value and catered sufficiently to student demand. Students' responses confirmed that placements met expectations and the perception of benefit remained after completion with 70 % (n = 14) reporting an overall positive experience, 75 % (n = 15) reporting a pleasant learning experience, 60 % (n = 12) feeling that their clinical skills were enhanced and 85 % (n = 17) believing that it would benefit other students. Placements contributed the equivalent of seven full time unskilled posts per annum to local health care services. While qualitative data revealed perceived 'mutual benefit' for both students and clinicians, this was qualified by

To determine the short- and long-term improvement in airflow dynamics in patients undergoing tracheobronchial stent placement for benign airway stenoses. Twenty-two patients underwent 34 tracheal and/or bronchial stent placement procedures for benign airway stenoses and had the results of pulmonary function tests available. Stent placement indications included bronchomalacia after lung transplantation (n = 11), postintubation stenoses (n = 6), relapsing polychondritis (n = 2), and 1 each of tracheomalacia, tracheal compression, and histoplasmosis. Six patients underwent more than one stent placement procedure (range: 2-7 procedures). The mean forced expiratory volume in one second (FEV(1) ), forced expiratory flow rate in the midportion of the forced vital capacity curve (FEF(25-75) ), forced vital capacity, and peak flow (PF) rate obtained before stent placement were compared with those immediately after stent placement and with those measurements most remote from stent placement using the paired two-tailed test. All patients reported improved respiratory function immediately after stent placement. The mean FEV(1), FEF(25-75), and PF rate improved significantly (p stent placement. On long-term follow-up averaging 15 months after stent placement, these parameters declined despite patients' subjective sense of improvement. Segregating the population into transplant and nontransplant airway stenosis etiologies, however, FEF(25-75) and PF rate remained significantly improved (p = 0.045, p = 0.027, respectively), over the long term for the latter. FEV increased after subsequent stent placements for patients receiving multiple stents. Stent placement for benign tracheobronchial stenoses provides significant immediate improvement in airflow dynamics. Long-term improvement in airflow obstruction may be expected, and additional stent placements may further improve pulmonary function.

This study aimed to evaluate the effect of lingual gauze swab placement on pulse oximeter readings in anaesthetised dogs and cats. Following anaesthetic induction, the following pulse oximeter probe configurations were performed: no gauze swab (control), placement of a gauze swab between the tongue and the probe, placement of different thicknesses of gauze swab, placement of red cotton fabric, placement of a sheet of white paper and placement of the probe and gauze swab on different locations on the tongue. Oxygen saturation (SpO 2 ) and peripheral perfusion index (PI) were recorded. Placement of a gauze swab between the pulse oximeter probe and the tongue in anaesthetised dogs and cats resulted in significantly higher SpO 2 values compared with the control group. In dogs, PI values were significantly higher than the control in all groups except the quarter thickness swab group. In cats, PI was significantly higher in the double thickness swab and white paper groups compared with the control. Cats had significantly higher SpO 2 and lower PI values than dogs. The authors propose that increased contact pressure is responsible for significantly higher SpO 2 and PI readings with the use of a lingual gauze swab resulting from changes in transmural pressure and arterial compliance.

Recent research has demonstrated that longitudinal integrated placements (LICs) are an alternative mode of clinical education to traditional placements. Extended student engagement in community settings provide the advantages of educational continuity as well as increased service provision in underserved areas. Developing and maintaining LICs require a differing approach to student learning than that for traditional placements. There has been little theoretically informed empirical research that has offered explanations of which are the important factors that promote student learning in LICs and the relationships between those factors. We explored the relationship between student learning, student perceptions of preparedness for practice and student engagement, in the context of a rural LIC. We used a sequential qualitative design employing thematic, comparative and relational analysis of data from student interviews (n = 18) to understand possible processes and mechanisms of student learning in the LIC. Through the theoretical lens of social learning systems, we identified two major themes; connectivity and preparedness for practice. Connectivity described engagement and relationship building by students, across formal and informal learning experiences, interprofessional interactions, social interactions with colleagues, interaction with patients outside of the clinical setting, and the extent of integration in the wider community. Preparedness for practice, reflected students' perceptions of having sufficient depth in clinical skills, personal and professional development, cultural awareness and understanding of the health system, to work in that system. A comparative analysis compared the nature and variation of learning across students. In a relational analysis, there was a positive association between connectivity and preparedness for practice. Connectivity is a powerful enabler of students' agentic engagement, collaboration, and learning within an LIC. It

The purpose of this paper was to evaluate the safety and technical success of TrapEase inferior vena cava filter placement via the subclavian vein. As of yet, no reports in the literature have specifically investigated the use of the subclavian vein as a route for deploying TrapEase vena cava filters. Retrospective chart review was conducted of 135 patients with attempted TrapEase inferior vena cava filter placement over a 2-year period. In a majority of cases, the choice of subclavian vein approach was based primarily on surgeon preference. Other circumstances for subclavian vein deployment included cervical immobilization secondary to trauma, desire for concomitant placement of a subclavian long-term central venous access catheter, and patient body habitus limiting exposure to the internal jugular vein. One hundred and thirty-five filters were placed over this 2-year period. The internal jugular vein approach was used in 56 patients, the femoral vein approach in 39 patients, and the subclavian vein approach in 40 patients. Thirty-nine of the 40 TrapEase filter placements using the subclavian vein were successful. Twenty-six were deployed through the right subclavian vein and 14 through the left subclavian vein. The single failed subclavian deployment was due to the inability to pass the guidewire adequately into the inferior vena cava after successful cannulation of the right subclavian vein. The average deployment time for subclavian vein placement was 26 minutes when TrapEase filter placement was the only procedure performed. No insertional complications were encountered, specifically no pneumothoraces confirmed by chest radiography or fluoroscopy. The subclavian vein provides an alternative site of access for the TrapEase inferior vena cava filter. This route is comparable to other alternative methods evaluated both in average deployment time and complication occurrence. Furthermore, the subclavian vein route is valuable in patients with limited central access

Students on health and social care degree programmes spend 50% of their time on practice placements. Because of the diversity of settings and the need to evidence their work, it is vital to understand the information and resource needs of placement students. The aim of this investigation was to understand the needs of placement students in terms of accessing resources whilst they are in the field in order to inform a guide to meet these needs. Focus groups were conducted with students on midwifery, social work and post-registration health professions degree programmes on three different sites across the region. Data were analysed using Thematic Content Analysis. Three themes emerged from the data: inequality, user education needs and students' solutions and strategies. It is essential to speak to placement students in order to understand their needs in terms of accessing and using library resources. The timing and content of information skills training is key to meeting student needs while on placement.

STUDENT PREDICTION SYSTEM FOR PLACEMENT TRAINING USING FUZZY INFERENCE SYSTEM

Directory of Open Access Journals (Sweden)

Ravi Kumar Rathore

2017-04-01

Full Text Available Proposed student prediction system is most vital approach which may be used to differentiate the student data/information on the basis of the student performance. Managing placement and training records in any larger organization is quite difficult as the student number are high; in such condition differentiation and classification on different categories becomes tedious. Proposed fuzzy inference system will classify the student data with ease and will be helpful to many educational organizations. There are lots of classification algorithms and statistical base technique which may be taken as good assets for classify the student data set in the education field. In this paper, Fuzzy Inference system has been applied to predict student performance which will help to identify performance of the students and also provides an opportunity to improve to performance. For instance, here we will classify the student’s data set for placement and non-placement classes.

To evaluate the effect of temporary stent graft placement in the treatment of benign anastomotic biliary strictures. Nine patients, five women and four men, 22-64 years old (mean, 47.5 years), with chronic benign biliary anastomotic strictures, refractory to repeated balloon dilations, were treated by prolonged, temporary placement of stent-grafts. Four patients had strictures following a liver transplantation; three of them in bilio-enteric anastomoses and one in a choledocho-choledochostomy. Four of the other five patients had strictures at bilio-enteric anastomoses, which developed after complications following laparoscopic cholecystectomies and in one after a Whipple procedure for duodenal carcinoma. In eight patients, balloon-expandable stent-grafts were placed and one patient was treated by insertion of a self-expanding stent-graft. In the transplant group, treatment of patients with bilio-enteric anastomoses was unsuccessful (mean stent duration, 30 days). The patient treated for stenosis in the choledocho-choledochostomy responded well to consecutive self-expanding stent-graft placement (total placement duration, 112 days). All patients with bilio-enteric anastomoses in the non-transplant group were treated successfully with stent-grafts (mean placement duration, 37 days). Treatment of benign biliary strictures with temporary placement of stent-grafts has a positive effect, but is less successful in patients with strictures developed following a liver transplant.

Endoscopic bilateral self-expandable metallic stent (SEMS) placement for malignant hilar biliary obstructions (MHBOs) is technically demanding, and a second SEMS insertion is particularly challenging. A simultaneous side-by-side (SBS) placement technique using a thinner delivery system may mitigate these issues. We aimed to examine the feasibility and efficacy of simultaneous SBS SEMS placement for treating MHBOs using a novel SEMS that has a 5.7-Fr ultra-thin delivery system. Thirty-four patients with MHBOs underwent SBS SEMS placement between 2010 and 2016. We divided the patient cohort into those who underwent sequential (conventional) SBS placement between 2010 and 2014 (sequential group) and those who underwent simultaneous SBS placement between 2015 and 2016 (simultaneous group), and compared the groups with respect to the clinical outcomes. The technical success rates were 71% (12/17) and 100% (17/17) in the sequential and simultaneous groups, respectively, a difference that was significant (P = .045). The median procedure time was significantly shorter in the simultaneous group (22 min) than in the sequential group (52 min) (P = .017). There were no significant group differences in the time to recurrent biliary obstruction (sequential group: 113 days; simultaneous group: 140 days) or other adverse event rates (sequential group: 12%; simultaneous group: 12%). Simultaneous SBS placement using the novel 5.7-Fr SEMS delivery system may be more straightforward and have a higher success rate compared to that with sequential SBS placement. This new method may be useful for bilateral stenting to treat MHBOs.

There is no study concerning safety and accuracy of pedicle screw placement in Marfan syndrome. The objective of this study is to investigate accuracy and safety of pedicle screw placement in scoliosis associated with Marfan syndrome. CT scanning was performed to analyze accuracy of pedicle screw placement. Pedicle perforations were classified as medial, lateral or anterior and categorized to four grades: ≤ 2 mm as Grade 1, 2.1-4.0 mm as Grade 2, 4.1-6.0 mm as Grade 3, ≥6.1 mm as Grade 4. Fully contained screws or with medial wall perforation ≤ 2 mm or with lateral wall perforation ≤ 6 mm and without injury of visceral organs were considered acceptable, otherwise were unacceptable. 976 pedicle screws were placed, 713 screws (73.1%) were fully contained within the cortical boundaries of the pedicle. 924 (94.7%) screws were considered as acceptable, and 52 (5.3%) as unacceptable. The perforation rate was higher using free-hand technique than O-arm navigation technique (30.8% VS. 11.4%, P Marfan syndrome is accuracy and safe. O-arm navigation was an effective modality to ensure the safety and accuracy of screw placement. Special attention should be paid when screws were placed at the lumber spine and the concave side of spine deformity to avoid the higher rate of complications.

Nguyen, Natalie; Renom-Guiteras, Anna; Meyer, Gabriele; Stephan, Astrid

2018-06-01

Background: Nursing home placement of people with dementia can become necessary when informal care is no longer sufficient. Informal carers experience the transition period as an additional burden. Aim: Experiences and views of informal carers and healthcare professionals regarding the transition from people with dementia to a nursing home are investigated to improve the support for informal carers. Method: This secondary analysis included data from all five focus groups with n = 30 informal carers and healthcare professionals conducted as part of the “RightTimePlaceCare” project. To supplement the material which resulted from a single interview question, a literature analysis with the same focus was conducted. Results: The merged results indicated that informal carers needed professional support early on at home until after the nursing home placement. Concerns regarding nursing homes, financial aspects and family related issues were important aspects in the decision making. Healthcare professionals recommended provision of early guidance regarding those matters and making own experiences with nursing homes. Healthcare professionals should serve as mediators during the transition process and improve the collaboration between service providers. Conclusions: Empowering families to make informed choices could be facilitated by offering advice at home about their options for formal support services, financial support, and housing solutions. Healthcare professionals should support caregivers to make a decision, coordinate the placement and to cope with the new situation.

PurposeTo evaluate the safety, efficacy, and long-term results of endovascular stent graft placement for ureteroarterial fistula (UAF).MethodsWe retrospectively analyzed stent graft placement for UAF performed at our institution from 2004 to 2012. Fistula location was assessed by contrast-enhanced computed tomography (CT) and angiography, and freedom from hematuria recurrence and mortality rates were estimated.ResultsStent graft placement for 11 UAFs was performed (4 men, mean age 72.8 {+-} 11.6 years). Some risk factors were present, including long-term ureteral stenting in 10 (91 %), pelvic surgery in 8 (73 %), and pelvic radiation in 5 (45 %). Contrast-enhanced CT and/or angiography revealed fistula or encasement of the artery in 6 cases (55 %). In the remaining 5 (45 %), angiography revealed no abnormality, and the suspected fistula site was at the crossing area between urinary tract and artery. All procedures were successful. However, one patient died of urosepsis 37 days after the procedure. At a mean follow-up of 548 (range 35-1,386) days, 4 patients (36 %) had recurrent hematuria, and two of them underwent additional treatment with secondary stent graft placement and surgical reconstruction. The hematuria recurrence-free rates at 1 and 2 years were 76.2 and 40.6 %, respectively. The freedom from UAF-related and overall mortality rates at 2 years were 85.7 and 54.9 %, respectively.ConclusionEndovascular stent graft placement for UAF is a safe and effective method to manage acute events. However, the hematuria recurrence rate remains high. A further study of long-term results in larger number of patients is necessary.

Reocclusion after Self-Expandable Metallic Stent Placement for Relieving Malignant Colorectal Obstruction as a Palliative Treatment

Full Text Available Self-expandable metallic stent (SEMS placement has been practiced in several hospitals in Japan, including ours, since January 2012. Here, we report the case of an 82-year-old Japanese man who presented to the hospital with a 1-week history of right hypochondrial pain. Computed tomography (CT findings indicated colorectal cancer. The laboratory findings on admission indicated severe anemia (red blood cell count, 426 × 104/μL; hemoglobin, 7.9 g/dL. We performed SEMS placement because the patient refused to undergo surgery. He did not attend any of the scheduled follow-up visits after SEMS placement. However, a year and a half after the SEMS placement, the patient attended the hospital because of difficulty in passing stool. A plain abdominal CT scan showed bowel reobstruction due to the ascending colon cancer after SEMS placement. We performed an emergency operation, ascending colostomy, on the same day. Colorectal stent placement may be a good treatment option for patients who refuse to undergo conventional therapeutic treatments or in those with unresectable colorectal cancer. Patients should be carefully followed up every few months after SEMS placement because of the risk of reocclusion.

Angirasa, Arush K; Barrett, Michael J

2008-01-01

The modified Brostrom procedure has been a proven procedure with excellent utility in the treatment of lateral ankle instability within limitation. Multiple variations of the original technique have been described in the literature to date. Included in these variations are differences in anchor placement, suture technique, or both. In this research study, we propose placing a bone screw anchor into the lateral shoulder of the talus rather than the typical placement at the lateral malleolus for anatomic reconstruction of the lateral ankle ligaments.

RJMCMC based Text Placement to Optimize Label Placement and Quantity

Science.gov (United States)

Touya, Guillaume; Chassin, Thibaud

2018-05-01

Label placement is a tedious task in map design, and its automation has long been a goal for researchers in cartography, but also in computational geometry. Methods that search for an optimal or nearly optimal solution that satisfies a set of constraints, such as label overlapping, have been proposed in the literature. Most of these methods mainly focus on finding the optimal position for a given set of labels, but rarely allow the removal of labels as part of the optimization. This paper proposes to apply an optimization technique called Reversible-Jump Markov Chain Monte Carlo that enables to easily model the removal or addition during the optimization iterations. The method, quite preliminary for now, is tested on a real dataset, and the first results are encouraging.

Disrupted Social Work Field Placement: Factors That Contribute to Premature Termination of BSW Students' Field Placement

Science.gov (United States)

Tyler, Janet

2012-01-01

According to R. Wayne ("Legal Guidelines for Dismissing Students Because of Poor Performance in the Field," 2004), there is a widely accepted assumption in social work education that field placement provides the best opportunity to evaluate students' goodness-of-fit with the profession and is therefore used to weed out unsuitable…

Simzar, Rahila M.; Domina, Thurston; Tran, Cathy

2016-01-01

This study uses student panel data to examine the association between Algebra placement and student motivation for mathematics. Changes in achievement goals, expectancy, and task value for students in eighth grade Algebra are compared with those of peers placed in lower-level mathematics courses (N = 3,306). In our sample, students placed in Algebra reported an increase in performance-avoidance goals as well as decreases in academic self-efficacy and task value. These relations were attenuated for students who had high mathematics achievement prior to Algebra placement. Whereas all students reported an overall decline in performance-approach goals over the course of eighth grade, previously high-achieving students reported an increase in these goals. Lastly, previously high-achieving students reported an increase in mastery goals. These findings suggest that while previously high-achieving students may benefit motivationally from eighth grade Algebra placement, placing previously average- and low-performing students in Algebra can potentially undermine their motivation for mathematics.

Thomas, Vimal Koshy; Paul, Cherish; Rajeev, Punchalil Chathappan; Palatty, Babu Urumese

2017-01-01

Background and Objectives: Over the past few years, ultrasonography is increasingly being used to confirm the correct placement of endotracheal tube (ETT). In our study, we aimed to compare it with the traditional clinical methods and the gold standard quantitative waveform capnography. Two primary outcomes were measured in our study. First was the sensitivity and specificity of ultrasonography against the other two methods to confirm endotracheal intubation. The second primary outcome assessed was the time taken for each method to confirm tube placement in an emergency setting. Methods: This is a single-centered, prospective cohort study conducted in an emergency department of a tertiary care hospital. We included 100 patients with indication of emergency intubation by convenient sampling. The intubation was performed as per standard hospital protocol. As part of the study protocol, ultrasonography was used to identify ETT placement simultaneously with the intubation procedure along with quantitative waveform capnography (end-tidal carbon dioxide) and clinical methods. Confirmation of tube placement and time taken for the same were noted by three separate health-care staffs. Results and Discussion: Out of the 100 intubation attempts, five (5%) had esophageal intubations. The sensitivity and specificity of diagnosis using ultrasonography were 97.89% and 100%, respectively. This was statistically comparable with the other two modalities. The time taken to confirm tube placement with ultrasonography was 8.27 ± 1.54 s compared to waveform capnography and clinical methods which were 18.06 ± 2.58 and 20.72 ± 3.21 s, respectively. The time taken by ultrasonography was significantly less. Conclusions: Ultrasonography confirmed tube placement with comparable sensitivity and specificity to quantitative waveform capnography and clinical methods. But then, it yielded results considerably faster than the other two modalities. PMID:28584427

Establishing placement test fit and performance: Serving local needs

Full Text Available Accountability in language education is often associated with top-down national policies unresponsive—or even hostile to—local needs; however, when accountability is driven by local stakeholders seeking to better understand and enhance their programs, it can foster productive cycles of action research and curriculum development. This paper reports on one such internally-motivated accountability effort, in which program insiders sought to determine the efficacy of a reading test being administered to a new population of students at one Colombian university. Descriptive statistics, reliability estimates, and item facility and discrimination measures were used to determine whether this test was sufficiently reliable and appropriately matched to test takers’ ability in order to warrant its use as part of a high-stakes English-language placement exam. A detailed analysis of this test is used not only to propose specific recommendations for revision but also to illustrate a useful set of statistical tools appropriate for test analysis in other language programs. Moreover, we conclude that the involvement of local instructors as part of an iterative, self-reflective, test development process provides opportunities for professional development and deeper engagement in accountability projects.

Purpose The benefits of community-based medical education for both students and teachers are becoming increasingly clear. However, there is paucity of information about the importance of incorporating students’ thoughts in the community-based education curriculum and the impact it has on their intentions to work in rural communities. The purpose of this study was to assess the teaching and learning expectations before and after placement of health-profession students going for community placement for the first time and make suggestions for improvement of the community-based programs. Methods The study was a cross-sectional survey with both structured and unstructured questions. Participants were recruited from four medical schools in Uganda targeting 100% participation of health-profession students going for community placement in 2014. In total, 454 and 305 participants responded to self-administered questionnaires before and after community placement, respectively; and they were from different programs and years of study. Results Students’ learning expectations before placement, in ranking were: community engagement, interpersonal skills, community diagnosis, clinical skills, lifestyle practices, and patient management. After placement, the order of ranking was: interpersonal skills, community engagement, community diagnosis, lifestyle practices, clinical skills, and patient management. Most of the students had prior rural exposure and expected to do community engagement. However, after community placement they indicated having developed interpersonal skills. The various health-profession students were able to harmoniously work together to achieve a common purpose, which they find difficult to do in a classroom environment. Conclusion Having student teams comprised of different health programs and years of study going for community placement together promoted peer-to-peer mentorship and enhanced team building during community placement.

2017-08-01

Cloud computing provides an effective way to dynamically provide numerous resources to meet customer demands. A major challenging problem for cloud providers is designing efficient mechanisms for optimal virtual machine Placement (OVMP). Such mechanisms enable the cloud providers to effectively utilize their available resources and obtain higher profits. In order to provide appropriate resources to the clients an optimal virtual machine placement algorithm is proposed. Virtual machine placement is NP-Hard problem. Such NP-Hard problem can be solved using heuristic algorithm. In this paper, Ant Colony Optimization based virtual machine placement is proposed. Our proposed system focuses on minimizing the cost spending in each plan for hosting virtual machines in a multiple cloud provider environment and the response time of each cloud provider is monitored periodically, in such a way to minimize delay in providing the resources to the users. The performance of the proposed algorithm is compared with greedy mechanism. The proposed algorithm is simulated in Eclipse IDE. The results clearly show that the proposed algorithm minimizes the cost, response time and also number of migrations.

Schalock, R L; Harper, R S

1978-11-01

Mentally retarded clients (N = 131) placed during a 2-year period from either an independent living or competitive employment training program were evaluated as to placement success. Thirteen percent returned to the training program. Successful independent living placement was related to intelligence and demonstrated skills in symbolic operations, personal maintenance, clothing care and use, socially appropriate behavior, and functional academics. Successful employment was related to sensorimotor, visual-auditory processing, language, and symbolic-operations skills. Major reasons for returning from a job to the competitive employment training program included inappropriate behavior or need for more training; returning from community living placement was related to money management, apartment cleanliness, social behavior, and meal preparation.

This study examines carer attributes associated with placement stability for teenagers growing up in long term foster care, focusing on unexpected placement success. We explored experiences and perceptions relating to family, belonging and commitment in a group of foster carers providing a stable placement for a young person who had not been expected to settle. These placements showed positive outcome, despite factors in the child's history that might have predicted otherwise. Seven foster carers were interviewed following a semi-structured guide, which covered their ideas about their relationship with the child in question, about the foster family, and the child's sense of belonging in foster and birth family. Analysis of carers' accounts of placements which had succeeded 'against the odds' revealed four major themes, described under the headings My Child--emotional bonding, the carers' enlarged view of family and their parental regard for the young person; Jam in the Sandwich--working within a 'compromised space' between Local Authority and birth family; Repair and Rebuild--the craft of fostering including managing the foster/birth family boundary; Sticking with It--resilience, tenacity and maintaining hopefulness. The carers' accounts offer pointers towards the ingredients of successful placements and prompt reflection on how these may be supported and promoted. They also highlight tensions inherent in the foster carer task relating to carers' parental functioning for young people in long-term foster care.

To analyze educational placement settings of Israeli children with cochlear implants (CIs) and evaluate the prognostic influence of the following demographic variables on mainstreaming: age at implantation, experience with CI, socioeconomic status, ethnicity, and parents' educational level. Retrospective review. Tertiary referral center. The study population comprised 245 children with severe-to-profound hearing impairment and at least 1 year of experience with a unilateral CI. Mean age at implantation was 4.5 ± 3.9 years, and mean duration of CI use was 5.4 ± 2.8 years. Follow-up review and statistical analysis of available data on educational placement after cochlear implantation. Placement in mainstream education. Regular schools were attended by 89 children (36.3%) and special education schools by 156 (63.7%). Variables found to be significantly associated with mainstream educational placement were younger age at implantation, higher level of parental education, higher socioeconomic status, and ethnicity. Multivariate analysis using a logistic regression model revealed that the factor with the highest positive correlation with mainstreaming was parental education level. Our results show that parental education, a variable that the health system cannot control, significantly influences postimplantation results in term of educational placement and can thus limit the chances of implanted children to achieve mainstream placement even when identified and implanted at an early age.

2016-01-01

The Commission for Hospital Hygiene and Infection Prevention (KRINKO) updated the recommendations for the prevention of catheter-associated urinary tract infections in 2015. This article will describe the implementation of these recommendations in Frankfurt's hospitals in autumn, 2015. In two non-ICU wards of each of Frankfurt's 17 hospitals, inspections were performed using a checklist based on the new KRINKO recommendations. In one large hospital, a total of 5 wards were inspected. The inspections covered the structure and process quality (operating instructions, training, indication, the placement and maintenance of catheters) and the demonstration of the preparation for insertion of a catheter using an empty bed and an imaginary patient, or insertion in a model. Operating instructions were available in all hospital wards; approximately half of the wards regularly performed training sessions. The indications were largely in line with the recommendations of the KRINKO. Alternatives to urinary tract catheters were available and were used more often than the urinary tract catheters themselves (15.9% vs. 13.5%). In accordance with the recommendations, catheters were placed without antibiotic prophylaxis or the instillation of antiseptic or antimicrobial substances or catheter flushing solutions. The demonstration of catheter placement was conscientiously performed. Need for improvement was seen in the daily documentation and the regular verification of continuing indication for a urinary catheter, as well as the omission of regular catheter change. Overall, the recommendations of the KRINKO on the prevention of catheter-associated urinary tract infections were adequately implemented. However, it cannot be ruled out that in situations with time pressure and staff shortage, the handling of urinary tract catheters may be of lower quality than that observed during the inspections, when catheter insertion was done by two nurses. Against this background, a sufficient

Full Text Available The purpose of the research is to unravel the steps of managing international equity placement strategic alliance (IEPSA. The steps of managing an IEPSA are obtained by conducting theoretical review. The theoretical reviews consist of theory of strategic alliance; definition, classification, and finding definition of an IEPSA, political and analytical considerations and the necessary steps. These steps of managing IEPSA can be classified into analyzing of macro consideration, micro consideration, domestic company’s stakeholder support, cultural understanding, strategic planning, internal support, human resource management, organizational arrangement, management control system, evolved cultural understanding, and evaluating results. In this research, the domestic partners who formed the IEPSAs are limited to State-Owned Enterprises (SOEs. The IEPSA was one of the means of privatization. The research will be beneficial for both foreign and domestic partners who form an IEPSA in the previous SOEs. By knowing the steps of managing the IEPSA both partners will be able to secure a successful implementation of IEPSA. By identifying the steps of managing the IEPSA, the stakeholder will not see IEPSA as threat rather as an opportunity to improve performance, to create synergy, and generate benefits for both partners and stakeholder. By knowing the necessary steps of managing the IEPSA, the stakeholder including society and politician will envisage the IEPSA as a means of effectively improving the SOEs’ performances.The research was espected to provide contributions for the research on strategic alliances. Apparently, there exist no literatures discussing about IEPSA in the domain of strategic alliances.

2015-10-01

Accurate and precise mediolateral foot placement is important for balance during gait, but is impaired post stroke. Mediolateral foot placement may be improved with ankle-foot orthosis use. The purpose of this study was to determine whether an ankle-foot orthosis improves mediolateral foot-placement ability during post-stroke ambulation. Crossover trial with randomized order of conditions tested. The accuracy and precision of mediolateral foot placement was quantified while subjects targeted four different randomized step widths. Subjects were tested with and without their regular non-rigid ankle-foot orthosis in two separate visits (order randomized). While ankle-foot orthosis use corrected foot and ankle alignment (i.e. significantly decreased mid-swing plantar flexion, p = 0.000), effects of ankle-foot orthosis use on hip hiking (p = 0.545), circumduction (p = 0.179), coronal plane hip range of motion (p = 0.06), and mediolateral foot-placement ability (p = 0.537) were not significant. While ankle-foot orthosis-mediated equinovarus correction of the affected foot and ankle was not associated with improved biomechanics of walking (i.e. proximal ipsilateral hip kinematics or mediolateral foot-placement ability), it may affect other aspects of balance that were not tested in this study (e.g. proprioception, cerebellar, vestibular, and cognitive mechanisms). Studies that investigate the effect of ankle-foot orthosis on gait can help advance stroke rehabilitation by documenting the specific gait benefits of ankle-foot orthosis use. In this study, we investigated the effect of ankle-foot orthosis use on mediolateral foot-placement ability, an aspect of gait important for maintaining balance. © The International Society for Prosthetics and Orthotics 2014.

Gallagher, S; O'Connell, B C; O'Connell, A C

2014-10-01

Many stainless steel crowns (SSCs) disrupt the occlusion in children, but stabilisation appears to occur within a short period post-placement. The extent and mechanism of these short-term occlusal changes in children are unknown. This study sought to determine whether placement of a SSC changes the maximum intercuspation position (MIP) in children, whether the MIP returns to normal within 4 weeks and whether local anaesthesia had an effect on the child's ability to achieve MIP. The T-Scan(®) III was used for the measurement of occlusal contacts. Reliability and reproducibility of the system was determined using a calibration exercise where MIP recordings were taken of eleven children not undergoing any dental treatment. For the main study, the percentage of total occlusal force on each tooth was recorded in 20 children preoperatively, after local anaesthesia, after SSC placement and 4 weeks postoperatively. There was no significant difference in MIP (P = 0·435) preoperatively and post-administration of local anaesthesia. There was a significant difference between the preoperative force on a tooth and the reading after crown placement (P = 0·0013, Wilcoxon test). By 4 weeks, there was no significant difference overall between post-SSC placement and the preoperative value for the tooth (P = 0·3). Administration of local anaesthesia did not affect the ability of a child to attain MIP. Maximum intercuspation position was disturbed by the placement of a SSC in seven of 20 cases. When MIP was disturbed, in most cases, it returned to preoperative status within 4 weeks of crown placement. © 2014 John Wiley & Sons Ltd.

How mothers talk about placement of their child with autism outside the home.

Corman, Michael K

2013-10-01

In this article I use insights offered by the poststructural shift and linguistic turn in social scientific inquiry, specifically discourse analysis, to explore mothers' talk about the placement of their child with autism outside of the home. By viewing mothers' talk as data, I bring to light the discourses and interpretive practices that mothers drew on to organize their talk of placement. In doing so, I provide insights into how mothers gave meaning to processes of placement while also expanding on commonsensical discursive notions of "good" mothering, caregiving, and family. Implications of the findings are discussed.

Optimum distributed generation placement with voltage sag effect minimization

Biswas, Soma; Goswami, Swapan Kumar; Chatterjee, Amitava

2012-01-01

Highlights: ► A new optimal distributed generation placement algorithm is proposed. ► Optimal number, sizes and locations of the DGs are determined. ► Technical factors like loss, voltage sag problem are minimized. ► The percentage savings are optimized. - Abstract: The present paper proposes a new formulation for the optimum distributed generator (DG) placement problem which considers a hybrid combination of technical factors, like minimization of the line loss, reduction in the voltage sag problem, etc., and economical factors, like installation and maintenance cost of the DGs. The new formulation proposed is inspired by the idea that the optimum placement of the DGs can help in reducing and mitigating voltage dips in low voltage distribution networks. The problem is configured as a multi-objective, constrained optimization problem, where the optimal number of DGs, along with their sizes and bus locations, are simultaneously obtained. This problem has been solved using genetic algorithm, a traditionally popular stochastic optimization algorithm. A few benchmark systems radial and networked (like 34-bus radial distribution system, 30 bus loop distribution system and IEEE 14 bus system) are considered as the case study where the effectiveness of the proposed algorithm is aptly demonstrated.

2014-04-01

Full Text Available Objective: To compare the acceptability and effectiveness of topical and infiltration anesthesia for placement of mini-implants used as temporary anchorage devices. Methods: The sample comprised 40 patients, 17 males and 23 females, whose mean age was 26 years old and who were all undergoing orthodontic treatment and in need for anchorage reinforcement. Mini-implants were bilaterally placed in the maxilla of all individuals, with infiltration anesthesia on one side and topical anesthesia on the other. These 40 patients completed two questionnaires, one before and another after mini-implant placement and pain was measured through a visual analog scale (VAS. The data collected were analyzed using descriptive statistics and the measurements of pain were compared by means of the non-parametric test of Mann-Whitney. Results: It was found that 60% of patients felt more comfortable with the use of topical anesthesia for mini-implant placement; 72.5% of patients described the occurrence of pressure during placement of the anchorage device as the most unpleasant sensation of the entire process; 62.5% of patients felt more pain with the use of topical anesthesia. Conclusion: It was concluded that patients had less pain with the use of infiltration anesthesia, and also preferred this type of anesthetic.

To evaluate the learning curve of hysteroscopic placement of tubal sterilization microinserts by gynecologists in the Netherlands. Prospective multicenter study (Canadian Task Force II-2). Ten community (teaching) hospitals in the Netherlands. A total of 631 women who underwent permanent sterilization by tubal microinserts. Hysteroscopic placement of tubal sterilization microinserts performed by 15 gynecologists experienced in performing operative hysteroscopy, starting from their very first placement. Effect of increasing experience in time on procedure time, pain score, successful bilateral placement, and complications. Bilateral successful placement with confirmation of adequate positioning at follow-up evaluation was achieved in 480 (76.1%) patients at first attempt and in 44 (7.0%) at second attempt. Median procedure time was 8.0 minutes (range: 3-40), and 31 (4.9%) patients were lost to follow-up evaluation. Gravidity showed to be a confounding factor and was consequently adjusted for. A learning curve was seen in a statistically significant decrease of procedure time with increasing experience. The decrease in procedure time extended to 11 to 15 cases and was followed by a plateau phase of the subsequent 60 cases. In contrast, pain scores, successful placement, and complication rate appeared not to improve with increasing experience. A learning curve for hysteroscopic tubal sterilization was seen for procedure time, but successful placement, pain score, and complication rate were not clearly influenced by increasing experience.

1998-05-01

Our purpose was to review the current status of carotid artery stent placement throughout the world. Surveys were sent to major interventional centers in Europe, North and South America, and Asia. Information from peer-reviewed journals was also included and supplemented the survey. The survey asked various questions regarding the patients enrolled, procedure techniques, and results of carotid stenting, including complications and restenosis. Of the centers which were sent surveys, 24 responded. The total number of endovascular carotid stent procedures that have been performed worldwide to date included 2,048 cases, with a technical success of 98.6%. Complications that occurred during carotid stent placement or within a 30-day period following placement were recorded. Overall, there were 63 minor strokes, with a rate of occurrence of 3.08%. The total number of major strokes was 27, for a rate of 1.32%. There were 28 deaths within a 30-day postprocedure period, resulting in a mortality rate of 1.37%. Restenosis rates of carotid stenting have been 4.80% at 6 mo. Endovascular stent treatment of carotid artery atherosclerotic disease is growing as an alternative to vascular surgery, especially for patients that are at high risk for standard carotid endarterectomy. The periprocedural risks for major and minor strokes and death are generally acceptable at this early stage of development.

Full Text Available The starting point of this study is the phenomenon termed misleading brand placement, a condition found where the brand placement in a movie depict the brand in a time where the brand has not yet exist, providing the brand an older age. As the brand used in the brand placement is a brand with high brand equity, the combination of older age and high brand equity is suspected to give a higher evaluation of the brand. To test these suspicions, three experiments were conducted to see the influence of consumer knowledge of the misleading brand placement, brand equity and movie liking toward the brand attitude. The results show that when consumers do not have knowledge of the misleading brand placement they are not affected by misleading brand placement; but when they know of the misleading brand placement, brand attitude tend to be still be high when brand equity is high; and finally, when brand equity is high, a positive movie liking can further strengthen brand equity in reducing the negative effect of the misleading brand placement.

In July of 2011 the U.S. Food and Drug Administration (FDA) released a safety communication entitled "UPDATE on Serious Complications Associated with Transvaginal Placement of Surgical Mesh for Pelvic Organ Prolapse." The stated purpose of this communication is to inform health care providers and patients that serious complications with placement of this mesh are not rare and that it is not clear that these repairs are more effective than nonmesh repair. The comments regarding efficacy are based on a systematic review of the scientific literature from 1996-2011 conducted by the FDA. Our review of the literature during this time yields some different conclusions regarding the safety and efficacy of mesh use in prolapse repair. It may be useful to consider this information prior to making recommendations regarding mesh use in prolapse surgery according to the recent UPDATE.

To make use of fiber-reinforced composite and the patient's own extracted teeth in fabricating a provisional restoration following immediate implant placement. Fiber-reinforced composites offer various possibilities in temporization of osseointegrating implants in the esthetic zone. In this chairside technique, the patient's own extracted teeth with fiber-reinforced composite were used to fabricate a provisional restoration after immediate implant placement. A putty index was made before extracting the teeth and placing the implants as planned. The index and crowns of the extracted teeth were used to make a nonloading, esthetic, chair-side provisional restoration after immediate implant placement. By using the patient's own teeth for pro-visionalization immediately after implant placement, acceptance is greatly enhanced.

Transforaminal lumbar interbody fusion (TLIF) is a frequently performed method of lumbar arthrodesis in patients failing medical management of back and leg pain. Accurate placement of the interbody graft and restoration of lordosis has been shown to be crucial when performing lumbar fusion procedures. We performed a single-surgeon, prospective, randomized study to determine whether a novel articulating versus traditional straight graft delivery arm system allows for superior graft placement and increased lordosis for single-level TLIF. Thirty consecutive patients undergoing single-level TLIF were included and prospectively randomized to one of the 2 groups (articulated vs. straight delivery arm system). Three radiographic characteristics were evaluated at 6-week follow-up: (1) degree of segmental lumbar lordosis at the fused level; (2) the percent anterior location of the interbody graft in disk space; and (3) the distance (mm) off midline of the interbody graft placement. Randomization yielded 16 patients in the articulated delivery arm cohort and 14 in the straight delivery arm cohort. The articulating delivery arm system yielded an average of 14.7-degree segmental lordosis at fused level, 35% anterior location, and 3.6 mm off midline. The straight delivery arm system yielded an average of 10.7-degree segmental lordosis at fused level, 46% anterior location, and 7.0 mm off midline. All 3 comparisons were statistically significant (Plordosis compared with a traditional straight delivery arm system.

Full Text Available Aim: The Commission for Hospital Hygiene and Infection Prevention (KRINKO updated the recommendations for the prevention of catheter-associated urinary tract infections in 2015. This article will describe the implementation of these recommendations in Frankfurt’s hospitals in autumn, 2015.Material and methods: In two non-ICU wards of each of Frankfurt’s , inspections were performed using a checklist based on the new KRINKO recommendations. In one large hospital, a total of were inspected. The inspections covered the structure and process quality (operating instructions, training, indication, the placement and maintenance of catheters and the demonstration of the preparation for insertion of a catheter using an empty bed and an imaginary patient, or insertion in a model.Results: Operating instructions were available in all hospital wards; approximately half of the wards regularly performed training sessions. The indications were largely in line with the recommendations of the KRINKO. Alternatives to urinary tract catheters were available and were used more often than the urinary tract catheters themselves (15.9% vs. 13.5%. In accordance with the recommendations, catheters were placed without antibiotic prophylaxis or the instillation of antiseptic or antimicrobial substances or catheter flushing solutions. The demonstration of catheter placement was conscientiously performed. Need for improvement was seen in the daily documentation and the regular verification of continuing indication for a urinary catheter, as well as the omission of regular catheter change.Conclusion: Overall, the recommendations of the KRINKO on the prevention of catheter-associated urinary tract infections were adequately implemented. However, it cannot be ruled out that in situations with time pressure and staff shortage, the handling of urinary tract catheters may be of lower quality than that observed during the inspections, when catheter insertion was done by two

Endoscopic reintervention for stent occlusions following bilateral self-expandable metallic stent (SEMS) placement for malignant hilar biliary obstruction (MHBO) is challenging, and time to recurrent biliary obstruction (RBO) of the revisionary stent remains unclear. We aimed to clarify a suitable reintervention method for stent occlusions following bilateral SEMS placement for MHBO. Between 2002 and 2014, 52 consecutive patients with MHBO who underwent endoscopic reintervention for stent occlusion after bilateral SEMS placement were enrolled at two university hospitals and one tertiary care referral center. We retrospectively evaluated the technical and functional success rates of the reinterventions, and the time to RBO of the revisionary stents. Technical and functional success rates of the reinterventions were 92% (48/52) and 90% (43/48), respectively. Univariate analysis did not determine any significant predictive factors for technical and functional failures. Median time to RBO of the revisionary stents was 68 days. Median time to RBO was significantly longer for revisionary SEMS placement than for plastic stent placement (131 days vs 47 days, respectively; log-rank test, P = 0.005). Revisionary SEMS placement was the only independent factor that was significantly associated with a longer time to RBO of the revisionary stent in the multivariate Cox proportional hazards analysis (hazard ratio 0.37; 95% confidence interval 0.14-0.95; P = 0.039). Revisionary SEMS placement is a suitable endoscopic reintervention method for stent occlusion following bilateral SEMS placement from the perspective of time to RBO of the revisionary stent. © 2016 Japan Gastroenterological Endoscopy Society.

Purpose: To treat the esophagotracheal fistula that was the main cause of death in patients with esophageal carcinoma, the placement of the stent was studied. Materials and methods: Under the fluoroscopic guidance, 28 stents (5 stents made in USA and 23 in China) were successfully implanted in all the 28 patients with esophagotracheal fistula. Results: The aphagia of the patients was greatly improved and a normal diet could be swallowed at once after the placement of the stents. The 27 cases of inhalation pneumonia that caused by the fistula was recovered. Conclusion: The result indicated that the treatment with the placement of the covered self-expanding stent is simple, safe, and effective for most patients with aphagia and pneumonia due to esophagotracheal fistula

This paper presents a critical review of research literature on the impact of international placements on the lives and practice of nurses. Health care institutions are progressively more aware of the need to respond to diverse patient populations and cultivate leaders to enrich the nursing profession, both locally and globally. One response has been to establish international exchange programmes for nursing students to give them experience of different cultures and health care systems. A search of the literature from 1980 to 2003 using electronic databases was undertaken using the databases CINAHL, ERIC, British Nursing Index, Web of Science, the BIDS Social Science Citation Index and Medline. The keywords used were 'international exchange experience', 'international studies', 'international education', 'international placement(s)', 'exchange programme(s)', combined with 'nurses/nursing', combined with 'evaluation', 'practice', 'education' and/or 'policy'. The papers retrieved used both qualitative and quantitative approaches and were scrutinized for recurring themes. Nurses reported significant changes in their personal development, perspectives on nursing practice and critical appraisal of health care systems. They also indicated an increased appreciation and sensitivity towards cultural issues and cross-cultural care. Moreover, differences in placement programmes, such as duration, preparation and debriefing were found to have affected the reported overall international placement experience. However, the primary effects of international placements were identified as personal development and transcultural adaptation. Students should be exposed to a variety of nursing experiences within the host country. This would give them a broad spectrum for comparisons between cultures, nursing practice and health care delivery in those cultures. Therefore, educational institutions are strongly encouraged to provide opportunities for students to participate in nursing care

This study aimed to evaluate the usefulness and outcomes of stent graft use in dysfunctional arteriovenous grafts. Eleven patients who underwent stent graft placement for a dysfunctional hemodialysis graft were included in this retrospective study. Expanded polytetrafluoroethylene covered stent grafts were placed at the venous anastomosis site in case of pseudoaneurysm, venous laceration, elastic recoil or residual restenosis despite the repeated angioplasty. The patency of the arteriovenous graft was evaluated using Kaplan-Meier analysis. Primary and secondary mean patency was 363 days and 741 days. Primary patency at 3, 6, and 12 months was 82%, 73%, and 32%, respectively. Secondary patency at the 3, 6, 12, 24, and 36 months was improved to 91%, 82%, 82%, 50%, and 25%, respectively. Fractures of the stent graft were observed in 2 patients, but had no effect on the patency. Stent graft placement in dysfunctional arteriovenous graft is useful and effective in prolonging graft patency.

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.

Despite the use of prokinetic agents, the overall success rate for postpyloric placement via a self-propelled spiral nasoenteric tube is quite low. This retrospective study was conducted in the intensive care units of 11 university hospitals from 2006 to 2016 among adult patients who underwent self-propelled spiral nasoenteric tube insertion. Success was defined as postpyloric nasoenteric tube placement confirmed by abdominal x-ray scan 24 hours after tube insertion. Chi-square automatic interaction detection (CHAID), simple classification and regression trees (SimpleCart), and J48 methodologies were used to develop decision tree models, and multiple logistic regression (LR) methodology was used to develop an LR model for predicting successful postpyloric nasoenteric tube placement. The area under the receiver operating characteristic curve (AUC) was used to evaluate the performance of these models. Successful postpyloric nasoenteric tube placement was confirmed in 427 of 939 patients enrolled. For predicting successful postpyloric nasoenteric tube placement, the performance of the 3 decision trees was similar in terms of the AUCs: 0.715 for the CHAID model, 0.682 for the SimpleCart model, and 0.671 for the J48 model. The AUC of the LR model was 0.729, which outperformed the J48 model. Both the CHAID and LR models achieved an acceptable discrimination for predicting successful postpyloric nasoenteric tube placement and were useful for intensivists in the setting of self-propelled spiral nasoenteric tube insertion. © 2016 American Society for Parenteral and Enteral Nutrition.

Mattei, Peter

2009-02-01

During minimally invasive operations, it is sometimes necessary to retrieve the end of a suture or a suture needle and bring it out through the abdominal wall. Using a standard needle and a length of suture, we have developed a simple device that allows the retrieval of a suture end during minimally invasive operations that require the placement of U-or stay stitches. The author has used the device described during more than 100 laparoscopic gastrostomy placement procedures and other operations involving the placement of U- or stay stitches with excellent results and no complications. Using a beveled hollow-bore needle and a loop of polypropylene suture, one can construct a simple device that allows the retrieval of a suture from within a body cavity during minimally invasive surgery, making the placement of U- and stay stitches easier and more precise.

Perforated schneiderian membrane repair during sinus augmentation in conjunction with immediate implant placement

Full Text Available Dental implant associated rehabilitation of the posterior maxilla poses unique challenge owing to the presence of pneumatized sinuses and atrophied alveolar bone. Sinus augmentation procedure to manage expanded sinuses frequently results in membrane tear resulting in unfavorable stabilization of the graft and associated bone regeneration. Simultaneous implant placement during sinus augmentation procedures frequently requires a minimal alveolar bone height, which when not present forces clinician to defer implant placement resulting in extended treatment duration and multiple surgical appointments. The present case report is about a piezosurgery assisted lateral wall osteotomy approach for sinus augmentation associated with membrane repair with simultaneous implant placement in the posterior maxilla.

Electronic nicotine delivery systems (ENDS) are widely available and come in a variety of forms, including disposable cigalikes and refillable tank systems. However, little is known about their placement at the point-of-sale. We explored the placement of various ENDS types among tobacco retailers. Systematic assessments at the point-of-sale were completed by trained data collectors in 90 tobacco retailers, including grocery stores, convenience stores, and pharmacies in North Carolina, U.S. Availability and placement of various ENDS types including cigalikes, e-hookahs, tank systems and e-liquids was recorded. Almost all retailers (97.8%) sold cigalikes; 41.4% sold devices labeled as e-hookahs; 54.4% sold tank systems and 56.2% sold e-liquids. Fewer than half of stores placed ENDS exclusively behind the counter; significant differences in ENDS placement were found by store type. Grocery stores carried cigalikes, tank systems and e-liquids and placed them exclusively behind the counter. Pharmacies only sold cigalikes; most placed them exclusively behind the counter (91.7%) with cessation aids and other tobacco products. Convenience stores carried all ENDS types and placed them with other tobacco products (55.1%) and candy (17.4%). Only about one-third of convenience stores placed ENDS exclusively behind the counter. This exploratory study shows ENDS availability and placement at the point-of-sale varies by retailer type. Pharmacies placed cigalikes with cessation aids behind the counter suggesting their ability to aid in smoking cessation. Most convenience stores placed ENDS in self-service locations, making them easily accessible to youth. Findings highlight the need for ENDS regulation at the point-of-sale. Our study highlights the need for regulatory efforts aimed at ENDS placement at the point-of-sale. While pharmacies and grocery stores offered fewer ENDS types and typically placed them in clerk-assisted locations, all ENDS types were found at convenience stores

Objectives This study aimed to define a safe corridor for 2.7 mm cortical sacroiliac screw insertion in the dorsal plane (craniocaudal direction) using radiography and CT, and in the transverse plane (dorsoventral direction) using CT in feline cadavers. A further aim was to compare the values obtained by CT with those previously reported by radiography in the transverse plane. Methods Thirteen pelvises were retrieved from feline cadavers and dissected to expose one of the articular surfaces of the sacrum. A 2.7 mm screw was placed in the sacrum to a depth of approximately 1 cm in each exposed articular surface. Dorsoventral radiography and CT scanning of each specimen were performed. Multiplanar reconstructions were performed to allow CT evaluation in both the dorsal and transverse planes. Calculations were made to find the maximum, minimum and optimum angles for screw placement in craniocaudal (radiography and CT) and dorsoventral (CT) directions when using a 2.7 mm cortical screw. Results Radiographic measurement showed a mean optimum craniocaudal angle of 106° (range 97-112°). The mean minimum angle was 95° (range 87-107°), whereas the mean maximum angle was 117° (108-124°). Measurement of the dorsal CT scan images showed a mean optimum craniocaudal angle of 101° (range 94-110°). The mean minimum angle was 90° (range 83-99°), whereas the mean maximum angle was 113° (104-125°). The transverse CT scan images showed a mean dorsoventral minimum angle of 103° (range 95-113°), mean maximum angle of 115° (104-125°) and mean optimum dorsoventral angle of 111° (102-119°). Conclusions and relevance An optimum craniocaudal angle of 101° is recommended for 2.7 mm cortical screw placement in the feline sacral body, with a safety margin between 99° and 104°. No single angle can be recommended in the dorsoventral direction and therefore preoperative measuring on individual cats using CT images is recommended to establish the ideal individual angle in the

The roots of molar and premolar maxillary teeth are often very close to the floor of the maxillary sinus. As a result, extraction of these teeth can leave an oral-antral communication or lead to a fistula that requires treatment. A woman with an oral-antral communication secondary to extraction of a maxillary molar is presented. The communication was closed by means of a bone graft harvested from the wall of the sinus (zygomatic bone). After 3 months, 2 dental implants were placed, one in the pterygoid area and the other with parasinusal angulation. Rehabilitation followed in the form of a screw-retained, fixed prosthesis 3 months after implant placement. There have been no complications after 1 year of follow-up. This surgical technique allowed closure of an oral-antral communication produced by molar extraction through placement of a zygomatic bone graft and subsequent placement of 2 dental implants.

To evaluate the outcomes of patients who underwent thoracoscopic wedge resection without chest drain placement. The subjects of this retrospective study were 89 patients, who underwent thoracoscopic wedge resection at our hospital between January, 2013 and July, 2015. A total of 45 patients whose underlying condition did not meet the following criteria were assigned to the "chest drain placement group" (group A): peripheral lesions, healthy lung parenchyma, no intraoperative air leaks, hemorrhage or effusion accumulation, and no pleural adhesion. The other 44 patients whose underlying condition met the criteria were assigned to the "no chest drain placement group" (group B). Patient characteristics, specimen data, and postoperative conditions were analyzed and compared between the groups. Group A patients had poorer forced expiratory volume in one second (FEV1) values, less normal spirometric results, significantly higher resected lung volume, a greater maximum tumor-pleura distance, and a larger maximum tumor size. They also had a longer postoperative hospital stay. There was no difference between the two groups in postoperative complications. Avoiding chest drain placement after a thoracoscopic wedge resection appears to be safe and beneficial for patients who have small peripheral lesions and healthy lung parenchyma.

Timing-Constrained FPGA Placement: A Force-Directed Formulation and Its Performance Evaluation

Directory of Open Access Journals (Sweden)

Srilata Raman

1996-01-01

Full Text Available In this paper we present a simple but efficient timing-driven placement algorithm for FPGAs. The algorithm computes forces acting on a logic block in the FPGA to determine its relative location with respect to other blocks. The forces depend on the criticality of nets shared between the two blocks. Unlike other net-based approaches, timing constraints are incorporated directly into the force equations to guide the placement. Slot assignment is then used to move the blocks into valid slot locations on the FPGA chip. The assignment algorithm also makes use of the delay information of nets so that the final placement is able to meet the timing criteria specified for the circuit. The novelty of the approach lies in the formulation of the force equations and the manner in which weights of the nets are dynamically altered to influence the placement. Experiments conducted on industrial test circuits and MCNC circuits give very promising results and indicate that the algorithm succeeds in significantly reducing the maximum delay in the circuit. In addition, routability is not adversely affected and running time is low.

Media exposure affects health, including obesity risk. Children's movies often contain food placements-frequently unhealthy foods. However, it is not known if these cues influence children's food choices or consumption after viewing. We explored whether children's snack choices or consumption differs based on: 1) recent exposure to movies with high versus low product placement of unhealthy foods; and 2) children's weight status. Children ages 9-11 were assigned to watch a high ("Alvin and the Chipmunks," n = 54) or low ("Stuart Little," n = 60) product-placement movie. After viewing, participants selected a snack choice from each of five categories, several of which were specifically featured in "Alvin." Uneaten snacks from each participant were weighed upon completion. Snack choice and amount consumed by movie were compared by t-tests, and differences in snack choices by movie were tested with logistic regression. Participants consumed an average of 800.8 kcal; mean kcal eaten did not vary by movie watched. Participants who watched the high product-placement movie had 3.1 times the odds (95% CI 1.3-7.2) of choosing cheese balls (most featured snack) compared to participants who watched the low product-placement movie. Children who were overweight or obese consumed a mean of 857 kcal (95% CI: 789-925) compared to 783 kcal (95% CI: 742-823, p = 0.09) for children who were underweight or healthy weight. Children's weight status did not significantly affect their choice of snack. Branding and obesogenic messaging in children's movies influenced some choices that children made about snack foods immediately following viewing, especially food with greatest exposure time in the film, but did not affect total calories consumed. Future studies should examine how the accumulation of these messages affects children's long-term food choices. Copyright © 2017 Elsevier Ltd. All rights reserved.

To date, there are limited radiation dose data on CT-guided procedures in pediatric patients. Our goal was to quantify the radiation dose associated with pediatric CT-guided drain placement and follow-up drain evaluations in order to estimate effective dose. We searched the electronic medical record and picture archiving and communication system (PACS) to identify all pediatric (<18 years old) CT-guided drain placements performed between January 2008 and December 2013 at our institution. We compiled patient data and radiation dose information from CT-guided drain placements as well as pre-procedural diagnostic CTs and post-procedural follow-up fluoroscopic abscess catheter injections (sinograms). Then we converted dose-length product, fluoroscopy time and number of acquisitions to effective doses using Monte Carlo simulations and age-appropriate conversion factors based on annual quality-control testing. Fifty-two drainages were identified with mean patient age of 11.0 years (5 weeks to 17 years). Most children had diagnoses of appendicitis (n=23) or inflammatory bowel disease (n=11). Forty-seven patients had diagnostic CTs, with a mean effective dose of 7.3 mSv (range 1.1-25.5 mSv). Drains remained in place for an average of 16.9 days (range 0-75 days), with an average of 0.9 (0-5) sinograms per patient in follow-up. The mean effective dose for all drainages and follow-up exams was 5.3 mSv (0.7-17.1) and 62% (32/52) of the children had effective doses less than 5 mSv. The majority of pediatric patients who have undergone CT-guided drain placements at our institution have received total radiation doses on par with diagnostic ranges. This information could be useful when describing the dose of radiation to parents and providers when CT-guided drain placement is necessary. (orig.)

To date, there are limited radiation dose data on CT-guided procedures in pediatric patients. Our goal was to quantify the radiation dose associated with pediatric CT-guided drain placement and follow-up drain evaluations in order to estimate effective dose. We searched the electronic medical record and picture archiving and communication system (PACS) to identify all pediatric (<18 years old) CT-guided drain placements performed between January 2008 and December 2013 at our institution. We compiled patient data and radiation dose information from CT-guided drain placements as well as pre-procedural diagnostic CTs and post-procedural follow-up fluoroscopic abscess catheter injections (sinograms). Then we converted dose-length product, fluoroscopy time and number of acquisitions to effective doses using Monte Carlo simulations and age-appropriate conversion factors based on annual quality-control testing. Fifty-two drainages were identified with mean patient age of 11.0 years (5 weeks to 17 years). Most children had diagnoses of appendicitis (n=23) or inflammatory bowel disease (n=11). Forty-seven patients had diagnostic CTs, with a mean effective dose of 7.3 mSv (range 1.1-25.5 mSv). Drains remained in place for an average of 16.9 days (range 0-75 days), with an average of 0.9 (0-5) sinograms per patient in follow-up. The mean effective dose for all drainages and follow-up exams was 5.3 mSv (0.7-17.1) and 62% (32/52) of the children had effective doses less than 5 mSv. The majority of pediatric patients who have undergone CT-guided drain placements at our institution have received total radiation doses on par with diagnostic ranges.

The aim of this project is to develop an image guided protocol for placement of a temporary anchorage device without surgically reflecting a mucoperiosteal flap. Eighteen orthodontic cases were selected for skeletal anchorage from the department of orthodontics at Case University. CBCT images of the subjects were taken using the Hitachi CB MercuRay system set at 15 mA, 120 kVp. CBCT images evaluated the ideal location for TAD placement in three dimensions. Horizontal and vertical linear measurements were taken from fixed dental landmarks to clearly define the location for placement. Transverse slices were used to evaluate the thickness of the buccal plate. Using the transverse view, the angle of insertion was determined such that the maximum buccal plate surface area would contact the screw. TADs were placed in the optimum location, with the most appropriate angle of insertion using a closed approach and with minimal local anesthesia and without flap elevation. Results: All TADs were placed without anatomic encroachment and enabled fixed orthodontic anchorage. (orig.)

Yetginer, Emre; Karasan, Ezhan

2002-07-01

In this paper we study regenerator placement and traffic engineering of restorable paths in Generalized Multipro-tocol Label Switching (GMPLS) networks. Regenerators are necessary in optical networks due to transmission impairments. We study a network architecture where there are regenerators at selected nodes and we propose two heuristic algorithms for the regenerator placement problem. Performances of these algorithms in terms of required number of regenerators and computational complexity are evaluated. In this network architecture with sparse regeneration, offline computation of working and restoration paths is studied with bandwidth reservation and path rerouting as the restoration scheme. We study two approaches for selecting working and restoration paths from a set of candidate paths and formulate each method as an Integer Linear Programming (ILP) prob-lem. Traffic uncertainty model is developed in order to compare these methods based on their robustness with respect to changing traffic patterns. Traffic engineering methods are compared based on number of additional demands due to traffic uncertainty that can be carried. Regenerator placement algorithms are also evaluated from a traffic engineering point of view.

To better understand the nature of sibling relationships among children in foster or adoptive placement and the challenges and processes involved in maintaining these relationships, we conducted an exploratory analysis of data collected from semi-structured interviews with caregivers of 14 foster and adopted children in San Diego County. We identified three patterns of placement histories and living situations which appeared to impact the degree of contact maintained with siblings: (1) children who had never lived together and were not currently placed together; (2) children who at some point lived with or were placed together with their siblings, but were now separated from them; and (3) children who had lived with their siblings all their life and were placed together with at least some of their siblings at the time of the interview. Children's current living situations and placement histories, caregivers' experiences and perceptions of feasibility and desirability of sibling contact, and the sibling relationship itself are primary determinants in the development and maintenance of contact between siblings. Implications for child welfare policy and practice are discussed.

We evaluated the technical feasibility and clinical efficacy of subintimal stent placement for long segment occlusion of the iliac artery. From March 2003 to February 2007, subintimal stent placement for long segment occlusion of the iliac artery of 24 limbs in 22 patients was analyzed retrospectively. Endovascular access was performed via the ipsilateral femoral artery in 7 cases, via the contralateral femoral artery in 6 cases, via both femoral arteries in 10 cases and via the brachial artery in one case. The SAFARI (subintimal arterial flossing with antegrade-retrograde intervention) technique using a microcatheter was performed to recannalize iliac artery occlusion in three cases. Medical records were reviewed for the collection of follow-up data. The stent patency rate was analyzed by use of the Kaplan-Meier method. Subintimal stent placement was technically successful in 23 of 24 procedures (95.8%). The mean ankle-brachial index (ABI) increased form 0.26 to 0.82. The Fontaine classification was improved after stent placement in all patients. Major complications occurred in four procedures: three distal embolizations and one arterial rupture. All of the complications were successfully treated by endovascular intervention. The primary stent patency rates at 6-months, 1-, 2-and 3-years were 95%, 88%, 88% and 88%, respectively. Subintimal stent placement is a safe and effective treatment for long segment occlusion of the iliac artery.

PurposeTo evaluate the safety, feasibility, and patency rates of radiologic placement of uncovered stents for the treatment of malignant colonic obstruction proximal to the descending colon.Materials and MethodsThis was a retrospective, single-center study. From May 2003 to March 2015, 53 image-guided placements of uncovered stents (44 initial placements, 9 secondary placements) were attempted in 44 patients (male:female = 23:21; mean age, 71.8 years). The technical and clinical success, complication rates, and patency rates of the stents were also evaluated. Technical success was defined as the successful deployment of the stent under fluoroscopic guidance alone and clinical success was defined as the relief of obstructive symptoms or signs within 48 h of stent deployment.ResultsIn total, 12 (27.3 %) patients underwent preoperative decompression, while 32 (72.7 %) underwent decompression with palliative intent. The technical success rate was 93.2 % (41/44) for initial placement and 88.9 % (8/9) for secondary placement. Secondary stent placement in the palliative group was required in nine patients after successful initial stent placement due to stent obstruction from tumor ingrowth (n = 7) and stent migration (n = 2). The symptoms of obstruction were relieved in all successful cases (100 %). In the palliative group, the patency rates were 94.4 % at 1 month, 84.0 % at 3 months, 64.8 % at 6 months, and 48.6 % at 12 months.ConclusionsThe radiologic placement of uncovered stents for the treatment of malignant obstruction proximal to the descending colon is feasible and safe, and provides acceptable clinical results.

Despite growing awareness of the benefits of interprofessional education and interprofessional collaboration (IPC), understanding how teams successfully transition to IPC is limited. Student exposure to interprofessional teams fosters the learners' integration and application of classroom-based interprofessional theory to practice. A further benefit might be reinforcing the value of IPC to members of the mentoring team and strengthening their IPC. The research question for this study was: Does training in IPC and clinical team facilitation and mentorship of pre-licensure learners during interprofessional clinical placements improve the mentoring teams' collaborative working relationships compared to control teams? Statistical analyses included repeated time analysis multivariate analysis of variance (MANOVA). Teams on four clinical units participated in the project. Impact on intervention teams pre- versus post-interprofessional clinical placement was modest with only the Cost of Team score of the Attitudes Towards Healthcare Team Scale improving relative to controls (p = 0.059) although reflective evaluations by intervention team members noted many perceived benefits of interprofessional clinical placements. The significantly higher group scores for control teams (geriatric and palliative care) on three of four subscales of the Assessment of Interprofessional Team Collaboration Scale underscore our need to better understand the unique features within geriatric and palliative care settings that foster superior IPC and to recognise that the transition to IPC likely requires a more diverse intervention than the interprofessional clinical placement experience implemented in this study. More recently, it is encouraging to see the development of innovative tools that use an evidence-based, multi-dimensional approach to support teams in their transition to IPC.

Schick, Brenda

2013-01-01

In the education of students who are deaf and hard of hearing (DHH), there is much debate about how placement affects educational outcomes and quality of life. This study examined the relationship between quality of life and educational placement that include and do not include other DHH youth. Participants included 221 DHH youth, ages 11–18 with bilateral hearing loss. Results showed that there were few differences in quality of life related to school placement (with age, gender, depression symptoms, and hearing level as covariates). For both participation and perceived stigma, there was an interaction between school placement and parent hearing status, with no single school placement showing the best results. DHH youth with hearing parents in schools specifically for DHH students scored lower than DHH with deaf parents in some domains (Participation and Perceived Stigma). When the DHH youth were compared with the general population, those in schools that included DHH students scored lower in some aspects of quality of life, particularly Self and Relationships. This study demonstrates that DHH students may not differ much in terms of quality of life across schools placements, but that there may be differences in subsets of DHH youth. PMID:23184867

Bifrontal (BF) placement of electrodes in electroconvulsive therapy (ECT) has become a popular alternative to bitemporal (BT) placement. This study compares the clinical efficacy, side effects, and rehospitalization rates of BT and BF electrode placement in a community hospital setting. Charts from 76 patients receiving ECT treatments at Harborview Medical Center from 1994 to 2000 were reviewed to extract data on the characteristics of the course of ECT, clinical response, total headaches, narcotic and nonsteroidal anti-inflammatory drug doses, as well as documentation of confusion, disorientation, memory loss, and treatment emergent need for assistance with activities of daily living. The BT patients experienced more clinical improvement during their stay (a 7-point greater change in Psychiatric Symptom Assessment Scale score, P < 0.05) and were significantly less likely to be rehospitalized within a 1-year time frame (odds ratio = 4.9, P = <0.05), even after controlling for relevant covariates. Although the two patient groups had equal rates of headache and analgesic administration, the BT placement caused significantly more cognitive impairment. This study suggests that BT electrode placement offers better efficacy but modestly greater cognitive impairment than BF electrode placement.

Observability-Enhanced PMU Placement Considering Conventional Measurements and Contingencies

Directory of Open Access Journals (Sweden)

M. Esmaili

2014-12-01

Full Text Available Phasor Measurement Units (PMUs are in growing attention in recent power systems because of their paramount abilities in state estimation. PMUs are placed in existing power systems where there are already installed conventional measurements, which can be helpful if they are considered in PMU optimal placement. In this paper, a method is proposed for optimal placement of PMUs incorporating conventional measurements of zero injection buses and branch flow measurements using a permutation matrix. Furthermore, the effect of single branch outage and single PMU failure is included in the proposed method. When a branch with a flow measurement goes out, the network loses one observability path (the branch and one conventional measurement (the flow measurement. The permutation matrix proposed here is able to model the outage of a branch equipped with a flow measurement or connected to a zero injection bus. Also, measurement redundancy, and consequently measurement reliability, is enhanced without increasing the number of PMUs this implies a more efficient usage of PMUs than previous methods. The PMU placement problem is formulated as a mixed-integer linear programming that results in the global optimal solution. Results obtained from testing the proposed method on four well-known test systems in diverse situations confirm its efficiency.

While much research exists on occupant packaging both proprietary and in the literature, more detailed research regarding user preferences for subjective ratings of steering wheel designs is sparse in published literature. This study aimed to explore the driver interactions with production steering wheels in four vehicles by using anthropometric data, driver hand placement, and driver grip design preferences for Generation-Y and Baby Boomers. In this study, participants selected their preferred grip diameter, responded to a series of questions about the steering wheel grip as they sat in four vehicles, and rank ordered their preferred grip design. Thirty-two male participants (16 Baby Boomers between ages 47 and 65 and 16 Generation-Y between ages 18 and 29) participated in the study. Drivers demonstrated different gripping behavior between vehicles and between groups. Recommendations for future work in steering wheel grip design and naturalistic driver hand positioning are discussed. Copyright © 2014. Published by Elsevier Ltd.

To review the use of three-dimensional ultrasound follow-up of the Essure micro-insert placement at three months for the identification of misplaced coils and complications. We conducted a retrospective cohort study of reproductive age women requesting permanent sterilization in a tertiary care ambulatory women's clinic. Women who underwent placement of the Essure micro-insert were assessed for appropriate positioning of the Essure micro-insert coil using three-dimensional ultrasound as well as hysterosalpingography when indicated. A total of 610 women who had undergone the Essure procedure with ultrasound follow-up at three months were retrospectively reviewed and in 524 (86%) the location and shape were both normal. The remaining 86 (15%) required hysterosalpingography to confirm proper placement, 34 because of a non-diagnostic ultrasound and the remaining 52 for a complication noted on ultrasound, including perforation, proximal or distal migration of the device, or device expulsion. Ultrasound can be used at three months after Essure placement to identify normal placement as well as misplaced and perforated devices.

In Finland, as many as 20 people have lost their lives in two school shootings within one year. This article describes trauma-theoretical rationale, planning, and implementation of acute and long-term psychosocial aftercare that was organized in Kauhajoki where one of the school shootings happened. The aftercare was embedded in the school community's everyday life to enhance easy access. The aftercare proceeded in 6 phases, involving the immediate support phase at the first 24 hr, the acute phase for the first 2 weeks, followed by a 5-month period of empowerment, normalization, and creating "a safe place." The habituation phase coincided with the completion of the renovation of the damaged school building and students returning to the scene. The first anniversary was marked by shared rituals and remembrance, and the follow-up phase lasted until the end of the aftercare in 2 years. The aftercare contained, for example, psychoeducation, screening, and services at community, group, and individual levels.

Pang Weng Ian

2017-01-01

Full Text Available Shift report is an essential method for nursing staff to carry out health care communication. The most important purpose of the shift report is to ensure the safety of patients and to provide continuous care. Nursing students are inadequate of clinical experience and rational organization during patient care. They may not be able to handle the critically ill patients and pass the messages to the following nursing staff. ISBAR (Identify, Situation, Background, Assessment and Recommendation tool is increasingly being utilized as a format for structured shift report communication. In this study, a scale of ISBAR principles is designed to provide students with self-assessment and teachers with evaluation, in a way to improve nursing students’ self-awareness of shift report. Hopefully, with the use of the scale of ISBAR, nursing students are able to complete shift report in systemic integrity and orderliness during clinical placement.

To analyze the feasibility of unilateral and bilateral translaminar screw placement in Koran population, and compare the acceptance rate using previously reported data in American population. The translaminar lengths, thickness, heights, and sagittal-diagonal measurements were performed. The feasibility analysis was performed using unilateral and bilateral 3.5 mm cervical screw placement on the CT scans within 0.5 mm of safety margin. We also performed radiographic analysis of the morphometric dimensions and the feasibility of unilateral and bilateral translaminar screw placement at C3-C7. Korean population had similar or significantly shorter translaminar lengths and thickness (lengths and thickness in C7 among males; lengths in C6-C7 and thickness in C4 among females) than American population, but had similar or significantly longer translaminar heights and sagittal-diagonal measurements (heights in C3-C7 and sagittal-diagonal measurements in C3-C6 among males; heights in C7 and sagittal-diagonal measurements in C3-C7 among females). Unilaterally, translaminar screw acceptance rates in C3-C7 were similar between Korean and American male population, but the rates in C4-C6 were significantly smaller between Korean and American female population. Bilaterally, translaminar screw acceptance rates in C3 and C5-C6 were significantly larger between Korean and American male population, but the rates in C3-C7 were similar between Korean and American female population. The feasibility of unilateral and bilateral translaminar screw placement is different depending on different ethnics. Subaxial cervical unilateral translaminar screw placement among Korean male population and bilateral placement at C4-C7 among Korean female population are more acceptable than American population.

Abdel-Aal, A.K.; Gaddikeri, S.; Saddekni, S.

2011-01-01

Peritoneal catheters are mainly used for peritoneal dialysis in patients with end-stage renal disease. Other uses of this catheter include intraperitoneal chemotherapy and gene therapy for ovarian cancer and draining of uncontrolled refractory ascites in patients with liver cirrhosis. Traditionally, surgeons place most of these peritoneal catheters either by laparoscopy or open laparotomy. We detail our percutaneous approach to placing peritoneal catheters using fluoroscopic guidance. We emphasize the use of additional ultrasound guidance, including gray scale and color Doppler ultrasound, to determine the safest puncture site and to guide the initial needle puncture in order to avoid bowel perforation and injury to epigastric artery. We present our experience in placing peritoneal catheters using this technique in 95 patients with various indications. Fluoroscopic guided percutaneous placement of peritoneal catheters is a safe, minimally invasive, and effective alternative to open surgical or laparoscopic placement.

However, there is paucity of information about the importance of incorporating students’ thoughts in the community-based education curriculum and the impact it has on their intentions to work in rural communities. The purpose of this study was to assess the teaching and learning expectations before and after placement of health-profession students going for community placement for the first time and make suggestions for improvement of the community-based programs. Methods: The study was a cross-sectional survey with both structured and unstructured questions. Participants were recruited from four medical schools in Uganda targeting 100% participation of health-profession students going for community placement in 2014. In total, 454 and 305 participants responded to self-administered questionnaires before and after community placement, respectively; and they were from different programs and years of study. Results: Students’ learning expectations before placement, in ranking were: community engagement, interpersonal skills, community diagnosis, clinical skills, lifestyle practices, and patient management. After placement, the order of ranking was: interpersonal skills, community engagement, community diagnosis, lifestyle practices, clinical skills, and patient management. Most of the students had prior rural exposure and expected to do community engagement. However, after community placement they indicated having developed interpersonal skills. The various health-profession students were able to

During video-assisted thoracic surgery (VATS), localization is sometimes needed to detect a target lesion that is too small and/or too far from the pleura. In 1995, Kanazawa et al. developed short hookwire and suture system. Since then, this system has been placed often for selected targets before VATS in Japan. This short hookwire and suture system is a representative preoperative localization method and the placement procedure is well-established. Its placement success rates are very high (range: 97.6%-99.6%), and dislodgement of this short hookwire rarely occurs with an incidence of 0.4%-2.5%. The most common complication of short hookwire placement is pneumothorax (incidence: 32.1%-68.1%), followed by pulmonary hemorrhage (incidence: 8.9%-41.6%). Complications are frequent; however, most complications are minor and asymptomatic. Copyright © 2018 Société française de radiologie. Published by Elsevier Masson SAS. All rights reserved.

Many people confronting mental health problems are excluded from participation in paid work. Supervisor engagement is essential for successful job placement. To elicit supervisor perspectives on the challenges involved in fostering integration to support individuals with mental health problems (trainees) in their job placement at ordinary companies. Explorative, qualitative designed study with a phenomenological approach, based on semi-structured interviews with 15 supervisors involved in job placements for a total of 105 trainees (mean 7, min-max. 1-30, SD 8). Data were analysed using qualitative content analysis. Superviors experience two interrelated dilemmas concerning knowledge of the trainee and degree of preferential treatment. Challenges to obtaining successful integration were; motivational: 1) Supervisors previous experience with trainees encourages future engagement, 2) Developing a realistic picture of the situation, and 3) Disclosure and knowledge of mental health problems, and continuity challenges: 4) Sustaining trainee cooperation throughout the placement process, 5) Building and maintaining a good relationship between supervisor and trainee, and 6) Ensuring continuous cooperation with the social security system and other stakeholders. Supervisors experience relational dilemmas regarding pre-judgment, privacy and equality. Job placement seem to be maximized when the stakeholders are motivated and recognize that cooperation must be a continuous process.

pplacer: linear time maximum-likelihood and Bayesian phylogenetic placement of sequences onto a fixed reference tree

Directory of Open Access Journals (Sweden)

Kodner Robin B

2010-10-01

Full Text Available Abstract Background Likelihood-based phylogenetic inference is generally considered to be the most reliable classification method for unknown sequences. However, traditional likelihood-based phylogenetic methods cannot be applied to large volumes of short reads from next-generation sequencing due to computational complexity issues and lack of phylogenetic signal. "Phylogenetic placement," where a reference tree is fixed and the unknown query sequences are placed onto the tree via a reference alignment, is a way to bring the inferential power offered by likelihood-based approaches to large data sets. Results This paper introduces pplacer, a software package for phylogenetic placement and subsequent visualization. The algorithm can place twenty thousand short reads on a reference tree of one thousand taxa per hour per processor, has essentially linear time and memory complexity in the number of reference taxa, and is easy to run in parallel. Pplacer features calculation of the posterior probability of a placement on an edge, which is a statistically rigorous way of quantifying uncertainty on an edge-by-edge basis. It also can inform the user of the positional uncertainty for query sequences by calculating expected distance between placement locations, which is crucial in the estimation of uncertainty with a well-sampled reference tree. The software provides visualizations using branch thickness and color to represent number of placements and their uncertainty. A simulation study using reads generated from 631 COG alignments shows a high level of accuracy for phylogenetic placement over a wide range of alignment diversity, and the power of edge uncertainty estimates to measure placement confidence. Conclusions Pplacer enables efficient phylogenetic placement and subsequent visualization, making likelihood-based phylogenetics methodology practical for large collections of reads; it is freely available as source code, binaries, and a web service.

The proportion of junior doctors required to complete psychiatry placements in the UK has increased, due in part to vacant training posts and psychiatry career workforce shortages, as can be seen across the world. The aim of this study was to understand the lived experience of a Foundation Year 1 junior doctor psychiatry placement and to understand how job components influence attitudes. The study was conducted using a cross-sectional qualitative phenomenological approach. Hospital and community psychiatry department settings in the North East of England, UK. In total, 14 Foundation Year 1 junior doctors were interviewed including seven men and seven women aged between 23 and 34 years. The majority had completed their medical degree in the UK and were White British. The lived experience of a junior doctor psychiatry placement was understood by three core themes: exposure to patient recovery, connectedness with others in the healthcare team and subjective interpretations of psychiatry. The experiences were moderated by instances of role definition, reaction to the specialty and the organisational fit of the junior doctor capacity in the specialty. The study reinforces and adds to the literature by identifying connectedness as being important for both job satisfaction and morale, which is currently damaged within the junior doctor population. The study provides in-depth insights into the lived experience of psychiatry placements and can be taken forward by educationalists to ensure the placements are meaningful experiences for junior doctors by developing role definition, belonging, structure and psychiatric care responsibility. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

To evaluate the safety and efficacy of unilateral covered stent placement in patients with malignant superior vena cava (SVC) syndrome. Between October 2008 and November 2012, expanded polytetrafluoroethylene-covered stent placement for malignant SVC syndrome was performed in 40 consecutive patients (35 men and five women; mean age, 61.4 years; range, 35-81 years). All covered stents were unilaterally placed within the SVC or across the venous confluence when needed to relieve venous obstruction and prevent tumor overgrowth, regardless of patency of contralateral brachiocephalic veins. Stent placement was technically successful in all patients. There were no major complications. Of the 37 patients symptomatic prior to stent placement, 34 (92%) experienced complete symptomatic relief 1-8 days after stent placement. Of the 29 patients who underwent covered stent placement across the venous confluence, nine patients had patent contralateral brachiocephalic veins prior to stent placement. However, no sign of SVC obstruction or contralateral upper extremity venous thrombosis was observed during the follow-up period. Kaplan-Meier analysis revealed median patient survival of 163 days. Stent occlusion occurred in four (10%) of 40 patents. Cumulative stent patency rates at 1, 3, 6, and 12 months were 95%, 92%, 86%, and 86%, respectively. Unilateral covered stent placement appears to be a safe and effective method for treating malignant SVC syndrome, despite the location of SVC occlusion.

Selection and placement of best management practices used to reduce water quality degradation in Lincoln Lake watershed

Science.gov (United States)

Rodriguez, Hector German; Popp, Jennie; Maringanti, Chetan; Chaubey, Indrajeet

2011-01-01

An increased loss of agricultural nutrients is a growing concern for water quality in Arkansas. Several studies have shown that best management practices (BMPs) are effective in controlling water pollution. However, those affected with water quality issues need water management plans that take into consideration BMPs selection, placement, and affordability. This study used a nondominated sorting genetic algorithm (NSGA-II). This multiobjective algorithm selects and locates BMPs that minimize nutrients pollution cost-effectively by providing trade-off curves (optimal fronts) between pollutant reduction and total net cost increase. The usefulness of this optimization framework was evaluated in the Lincoln Lake watershed. The final NSGA-II optimization model generated a number of near-optimal solutions by selecting from 35 BMPs (combinations of pasture management, buffer zones, and poultry litter application practices). Selection and placement of BMPs were analyzed under various cost solutions. The NSGA-II provides multiple solutions that could fit the water management plan for the watershed. For instance, by implementing all the BMP combinations recommended in the lowest-cost solution, total phosphorous (TP) could be reduced by at least 76% while increasing cost by less than 2% in the entire watershed. This value represents an increase in cost of 5.49 ha-1 when compared to the baseline. Implementing all the BMP combinations proposed with the medium- and the highest-cost solutions could decrease TP drastically but will increase cost by 24,282 (7%) and $82,306 (25%), respectively.

Wiring economy has successfully explained the individual placement of neurons in simple nervous systems like that of Caenorhabditis elegans [1-3] and the locations of coarser structures like cortical areas in complex vertebrate brains [4]. However, it remains unclear whether wiring economy can explain the placement of individual neurons in brains larger than that of C. elegans. Indeed, given the greater number of neuronal interconnections in larger brains, simply minimizing the length of connections results in unrealistic configurations, with multiple neurons occupying the same position in space. Avoiding such configurations, or volume exclusion, repels neurons from each other, thus counteracting wiring economy. Here we test whether wiring economy together with volume exclusion can explain the placement of neurons in a module of the Drosophila melanogaster brain known as lamina cartridge [5-13]. We used newly developed techniques for semiautomated reconstruction from serial electron microscopy (EM) [14] to obtain the shapes of neurons, the location of synapses, and the resultant synaptic connectivity. We show that wiring length minimization and volume exclusion together can explain the structure of the lamina microcircuit. Therefore, even in brains larger than that of C. elegans, at least for some circuits, optimization can play an important role in individual neuron placement. Copyright © 2011 Elsevier Ltd.

To document the annual number of advanced pharmacy practice experience (APPE) placement changes for students across 5 colleges and schools of pharmacy, identify and compare initiating reasons, and estimate the associated administrative workload. Data collection occurred from finalization of the 2008-2009 APPE assignments throughout the last date of the APPE schedule. Internet-based customized tracking forms were used to categorize the initiating reason for the placement change and the administrative time required per change (0 to 120 minutes). APPE placement changes per institution varied from 14% to 53% of total assignments. Reasons for changes were: administrator initiated (20%), student initiated (23%), and site/preceptor initiated (57%) Total administrative time required per change varied across institutions from 3,130 to 22,750 minutes, while the average time per reassignment was 42.5 minutes. APPE placements are subject to high instability. Significant differences exist between public and private colleges and schools of pharmacy as to the number and type of APPE reassignments made and associated workload estimates.

Immediate placement of implants into infected sites: a systematic review.

Traditionally, before placing dental implants, the compromised teeth are removed and the extraction sockets are left to heal for several months. To preserve the alveolar bone level from the collapse caused by healing and to reduce treatment time in situations in which tooth extraction precedes implant placement, some clinicians began to install the implant immediately into the postextraction socket without waiting for the site to heal. The purpose of this study was to review the literature regarding treatment outcomes of immediate implant placement into sites exhibiting pathology after clinical procedures to perform the decontamination of the implant's site. The following questions were raised: Does the presence of periodontal or endodontic infection affect immediate implant placement success? What is suggested to address the infection in the socket prior to immediate placement? An electronic search in PubMed (U.S. National Library of Medicine, Bethesda, MD, USA) was undertaken in March 2013. The titles and abstracts from these results were read to identify studies within the selection criteria. Eligibility criteria included both animal and human studies, and excluded any review and case reports articles. The publication's intervention had to have been implant placement into a site classified as having an infection (periapical, endodontic, perioendodontic, and periodontal). The search strategy initially yielded 706 references. Thirty-two studies were identified within the selection criteria, from which nine were case reports and review articles and were excluded. Additional hand-searching of the reference lists of selected studies yielded five additional papers. The high survival rate obtained in several studies supports the hypothesis that implants may be successfully osseointegrated when placed immediately after extraction of teeth presenting endodontic and periodontal lesions, provided that appropriate clinical procedures are performed before the implant

This study was performed to evaluate the changes of jaw bone density around the dental implant after placement using computed tomography scan (CT-Scan). This retrospective study consisted of 30 patients who had lost 1 posterior tooth in maxilla or mandible and installed dental implant. The patients took CT-Scan before and after implant placement. Hounsfield Unit (HU) was measured around the implants and evaluated the difference of HU before and after implant installation. The mean HU of jaw bone was 542.436 HU and 764.9 HU before and after implant placement, respectively (p<0.05). The means HUs for male were 632.3 HU and 932.2 HU and those for female 478.2 HU and 645.5 HU before and after implant placement, respectively (p<0.05). Also, the jaw bone with lower density needed longer period for implant procedure and the increased change of HU of jaw bone was less in the cases which needed longer period for osseointegration. CT-Scan could be used to assess the change of bone density around dental implants. Bone density around dental implant was increased after placement. The increased rate of bone density could be determined by the quality of jaw bone before implant placement.

The scientific impact of nations: journal placement and citation performance.

Directory of Open Access Journals (Sweden)

Matthew J Smith

Full Text Available International collaboration is becoming increasingly important for the advancement of science. To gain a more precise understanding of how factors such as international collaboration influence publication success, we divide publication success into two categories: journal placement and citation performance. Analyzing all papers published between 1996 and 2012 in eight disciplines, we find that those with more countries in their affiliations performed better in both categories. Furthermore, specific countries vary in their effects both individually and in combination. Finally, we look at the relationship between national output (in papers published and input (in citations received over the 17 years, expanding upon prior depictions by also plotting an expected proportion of citations based on Journal Placement. Discrepancies between this expectation and the realized proportion of citations illuminate trends in performance, such as the decline of the Global North in response to rapidly developing countries, especially China. Yet, most countries' show little to no discrepancy, meaning that, in most cases, citation proportion can be predicted by Journal Placement alone. This reveals an extreme asymmetry between the opinions of a few reviewers and the degree to which paper acceptance and citation rates influence career advancement.

Percutaneous transcholecystic approach for an experiment of biliary stent placement: an experimental study in dogs

To determine, in an experimental study of biliary stent placement, the usefulness and safety of the percutaneous transcholecystic approach and the patency of a newly designed biliary stent. A stent made of 0.15-mm-thick nitinol wire, and 10 mm in diameter and 2 cm in length, was loaded in an introducer with an 8-F outer diameter. The gallbladders of seven mongrel dogs were punctured with a 16-G angiocath needle under sonographic guidance, and cholangiography was performed. After anchoring the anterior wall of the gallbladder to the abdominal wall using a T-fastener, the gallbladder body was punctured again under fluoroscopic guidance. The cystic and common bile ducts were selected using a 0.035-inch guide wire and a cobra catheter, and the stent was placed in the common bile duct. Post-stenting cholangiography was undertaken, and an 8.5-F drainage tube was inserted in the gallbladder. Two dogs were followed-up and sacrificed at 2,4 and 8 weeks after stent placement, respectively, and the other expired 2 days after stent placement. Follow-up cholangiograms were obtained before aninmal was sacrified, and a pathologic examination was performed. Stent placement was technically successful in all cases. One dog expired 2 days after placement because of bile peritonitis due to migration of the drainage tube into the peritoneal cavity, but the other six remained healthy during the follow-up period. Cholangiography performed before the sacrifice of each dog showed that the stents were patent. Pathologic examination revealed the proliferation of granulation tissue at 2 weeks, and complete endothelialization over the stents by granulation tissue at 8 weeks. Percutaneous transcholecystic biliary stent placement appears to be safe, easy and useful. After placement, the stent was patent during the follow-period.

This article uses data from a field experiment in Sweden to analyze the effects of active placement efforts. In particular, the relative efficiency between combining job-search monitoring and job-search assistance, and monitoring alone, is analyzed. Although the impact estimates are generally imprecisely estimated, a general conclusion is that placement programs are effective policies in increasing the job exit rate for various groups of unemployed. I find that monitoring of job search is an efficient method to increase off-unemployment exit rate both alone and combined with job-search assistance services. The results, however, indicate that the combined services generate more permanent job exits. © The Author(s) 2014.

2017-11-01

Optimal sensor placement is a central challenge in the prediction, estimation and control of fluid flows. We reinterpret sensor placement as optimizing discrete samples of coherent fluid structures for full state reconstruction. This permits a drastic reduction in the number of sensors required for faithful reconstruction, since complex fluid interactions can often be described by a small number of coherent structures. Our work optimizes point sensors using the pivoted matrix QR factorization to sample coherent structures directly computed from flow data. We apply this sampling technique in conjunction with various data-driven modal identification methods, including the proper orthogonal decomposition (POD) and dynamic mode decomposition (DMD). In contrast to POD-based sensors, DMD demonstrably enables the optimization of sensors for prediction in systems exhibiting multiple scales of dynamics. Finally, reconstruction accuracy from pivot sensors is shown to be competitive with sensors obtained using traditional computationally prohibitive optimization methods.

Health workforce shortages have driven the Australian and other Western governments to invest in engaging more health professional students in rural and remote placements. The aim of this qualitative study was to provide an understanding of the lived experiences of students undertaking placements in various nonmetropolitan locations across Australia. In addition to providing their suggestions to improve rural placements, the study provides insight into factors contributing to positive and negative experiences that influence students' future rural practice intentions. Responses to open-ended survey questions from 3,204 students from multiple health professions and universities were analyzed using two independent methods applied concurrently: manual thematic analysis and computerized content analysis using Leximancer software. The core concept identified from the thematic analysis was "ruralization of students' horizons," a construct representing the importance of preparing health professional students for practice in nonmetropolitan locations. Ruralization embodies three interrelated themes, "preparation and support," "rural or remote health experience," and "rural lifestyle and socialization," each of which includes multiple subthemes. From the content analysis, factors that promoted students' rural practice intentions were having a "positive" practice experience, interactions with "supportive staff," and interactions with the "community" in general. It was apparent that "difficulties," eg, with "accommodation," "Internet" access, "transport," and "financial" support, negatively impacted students' placement experience and rural practice intentions. The study findings have policy and practice implications for continuing to support students undertaking regional, rural, and remote placements and preparing them for future practice in nonmetropolitan locations. This study may, therefore, further inform ongoing strategies for improving rural placement experiences and

Primary tracheal amyloidosis (PTA) can lead to airway obstructions, and patients with severe PTA should undergo bronchoscopic interventions in order to maintain airway patency. Focal airway involvements with amyloidosis can only be treated with mechanical dilatation. However, the PTA with diffused airway involvements and concomitant cartilage destructions requires stent placement. Limited information regarding the usefulness of silicone stents in patients with PTA has been released. Therefore, we report a case of diffused PTA with tracheomalacia causing severe cartilage destruction, which is being successfully managed with bronchoscopic interventions and silicone stent placements.

Effect of urea placement on leaching losses of nitrogen from flooded rice soils

International Nuclear Information System (INIS)

Vlek, P.L.G.; Byrnes, B.H.; Craswell, E.T.

1980-01-01

In an effort to provide an explanation for the reported variability in fertilizer N efficiency from deep-placed urea on flooded rice, a set of controlled experiments was conducted to evaluate the effect of water percolation on fertilizer loss and plant uptake from 15 N labeled urea supergranules. Three soils of different texture (silt loam-clay) were subjected to various percolation rates (0-20 mm/day) while planted to rice which was harvested after approximately 40 days. The results indicate that moderate to high percolation through silt loam soil will lead to significant fertilizer N losses and drastically decrease the fertilizer uptake by plants. The permeability of the clay soil was too low for any leaching to take place. It is therefore concluded that deep placement of urea supergranules not be recommended in soils where percolation rates may exceed 5 mm/day, particularly if the cation exchange capacity of the soil is low. This experiment points to the need of evaluating and reporting the percolation rates in soils where experiments with supergranular urea are conducted. (orig.)

Full Text Available Cerebral cysticercosis is common, but the possibility for repeated occurrence of peritoneal catheter blockage caused by neurocysticercosis (NCC after two revisions following ventriculoperitoneal shunt placement for hydrocephalus is unusual. Herein, we describe one rare case in which peritoneal catheter revision was performed two times unsuccessfully. Endoscopic cysternostomy rather than peritoneal catheter adjustment was performed successfully, and histopathological examination of excised cystic samples confirmed NCC in our hospital. The present case highlights the need for awareness of NCC as a possible etiology of hydrocephalus, especially in developing countries. Uncommon findings in both lateral ventricles following low-field magnetic resonance imaging scans as well as the rarity of this infection involved in unusual location play important roles in misdiagnosis and incorrect treatment for hydrocephalus; thus, endoscopic cysternostomy, rather than multiple shunt adjustment of the peritoneal end, is recommended in the selected patient. To the best of our knowledge, this is the first report describing the misdiagnosis and inappropriate treatment of hydrocephalus caused by cerebral cysticercosis in China.
