Suggestibility was measured in 44 adult patients who recovered memories and in 31 comparison patients. Results suggest that patients who recovered memories were significantly less suggestible than average. Control patients with no history of sexual abuse were more at risk for altering memory to suggestive prompts. (Author/PB)

Completeness, supervenience and ontology

Maudlin, Tim W E

2007-01-01

In 1935, Einstein, Podolsky and Rosen raised the issue of the completeness of the quantum description of a physical system. What they had in mind is whether or not the quantum description is informationally complete, in that all physical features of a system can be recovered from it. In a collapse theory such as the theory of Ghirardi, Rimini and Weber, the quantum wavefunction is informationally complete, and this has often been taken to suggest that according to that theory the wavefunction is all there is. If we distinguish the ontological completeness of a description from its informational completeness, we can see that the best interpretations of the GRW theory must postulate more physical ontology than just the wavefunction

BACKGROUND: Consecutive Candida glabrata isolates recovered from a patient in an intensive care unit were resistant to amphotericin B (minimum inhibitory concentration, up to 32 mu g/mL; determined by Etest [AB Biodisk]). Analyses at the national reference laboratory showed that some isolates were...... also resistant to azoles and caspofungin. In this study, 4 isolates were studied thoroughly using susceptibility assays and a mouse model and to determine clonality. METHODS: Different broth microdilution tests, Etests, and time-kill studies for antifungals were performed in different media. Three...... isolates obtained from nonrelated patients, and a reference strain. RESULTS: The murine model indicated that 1 isolate was resistant to amphotericin B, 1 had intermediate susceptibility, and 1 was fully susceptible. Two of the 3 isolates were resistant to caspofungin. Microdilution methods did not reliably...

There is a poor association between the dentist's evaluation of denture quality and patients' satisfaction with their dentures. Possible differences between dental professionals and patients' expectations might help explain differences in outcome evaluations. This study compared scores given by a dentist, a dental technician and patients for their expectations before and their final evaluation after complete dentures treatment. Twenty completely edentulous patients, a prosthodontist and a dental technician provided scores for the expected aesthetic and functional results of their dentures based on a visual analogue scale at baseline. Post-treatment completion ratings were given after adjustments, by dentist and patients. The dental technician provided post-treatment completion ratings after completing the dentures. The patients had higher expectations than the dental technician and the dentist perceived for both aesthetic and function (P < 0.001). The patients also presented higher post-treatment completion ratings than the dental professionals perceived for final aesthetics (P = 0.016, Kendall's W = 0.207) and function (P = 0.002, Kendall's W = 0.303). Only the dentist presented a statistically significant difference between expectations (lower) and final (higher) outcomes for aesthetics (P = 0.017) and function (P = 0.003). There was no correlation between expectations and post-treatment completion ratings according to the patients' age. There was also no correlation between the patients' gender and expectation scores. Patients presented higher expectations regarding their dentures than dental professionals. The dentist believed that dentures would bring fewer benefits than patients did, but his perception of denture benefits post-treatment was significantly higher than his expectations.

Summary We hypothesized that sirolimus, an mTOR inhibitor, may be effective in patients with autoimmune lymphoproliferative syndrome (ALPS) and treated patients who were intolerant to or failed other therapies. Four patients were treated for autoimmune cytopenias; all had a rapid complete or near complete response. Two patients were treated for autoimmune arthritis and colitis, demonstrating marked improvement. Three patients had complete resolution of lymphadenopathy and splenomegaly and all patients had a reduction in double negative T cells, a population hallmark of the disease. Based on these significant responses, we recommend that sirolimus be considered as second-line therapy for patients with steroid-refractory disease. PMID:19208097

Full Text Available Bacteraemia is associated with significant morbidity and mortality and timely access to relia-ble information is essential for health care administrators. Therefore, we investigated the complete-ness of bacteraemia registration in the Danish National Patient Registry (DNPR containing hospital discharge diagnoses and surgical procedures for all non-psychiatric patients. As gold standard we identified bacteraemia patients in three defined areas of Denmark (~2.3 million inhabitants from 2000 through 2011 by use of blood culture data retrieved from electronic microbiology databases. Diagnoses coded according to the International Classification of Diseases, version 10, and surgical procedure codes were retrieved from the DNPR. The codes were categorized into seven groups, ranked a priori according to the likelihood of bacteraemia. Completeness was analysed by contin-gency tables, for all patients and subgroups. We identified 58,139 bacteraemic episodes in 48,450 patients; 37,740 episodes (64.9% were covered by one or more discharge diagnoses within the sev-en diagnosis/surgery groups and 18,786 episodes (32.3% had a code within the highest priority group. Completeness varied substantially according to speciality (from 17.9% for surgical to 36.4% for medical, place of acquisition (from 26.0% for nosocomial to 36.2% for community, and mi-croorganism (from 19.5% for anaerobic Gram-negative bacteria to 36.8% for haemolytic strepto-cocci. The completeness increased from 25.1% in 2000 to 35.1% in 2011. In conclusion, one third of the bacteraemic episodes did not have a relevant diagnosis in the Danish administrative registry recording all non-psychiatric contacts. This source of information should be used cautiously to iden-tify patients with bacteraemia.

Heart failure (HF) with recovered ejection fraction (EF) is emerging as a different HF subtype. There is little information about his clinical profile in hospitals that are not a reference. We analysed characteristics and prognosis in patients with recovered HF followed prospectively in the HF Unit of a non-tertiary hospital. A total of 431 patients with HF with reduced EF were followed (median 50 months, 79.3% males, mean age 70.3±12.2years). Of the patients, 26.9% (N 116) recovered EF, mainly in the first year of follow-up (76.7%). Compared with patients that did not recovered EF in the follow-up, they were younger, rate of ischemic origin of cardiomyopathy was less frequent and presented less comorbidity. Mortality was lower in patients with recovered HF (survival median of 85.2±2.1 vs. 74.2±1.9 months [log-rank χ 2 11.5, P=0.001], hazard ratio 0.37, 95% confidence interval [CI]: 0.21-0.67, P=0.002). Aetiology of deaths was not mainly secondary to HF. Younger age of 68 years (odds ratio [OR] 0-98, 95% CI: 0.96-0,99; P=0.025), ischemic origin (OR 1.12, 95% CI: 1.01-1.21; P=0.003) and use of aldosterone antagonists (OR 1.89, 95% CI: 1.09-3.26; P=0.023) were the variables independently associated to normalisation of EF. HF with recovered EF is a frequent phenomenon. It has a more favourable clinical course, prognosis and basal characteristics than HF with persistent reduced EF. Further studies are needed to identify natural history and optimal medications for HF-recovered patients. Copyright © 2018 Elsevier España, S.L.U. All rights reserved.

Amygdala alterations during an emotional conflict task in women recovered from anorexia nervosa.

2016-02-28

The pathophysiology of anorexia nervosa (AN) is not completely understood, but research suggests that alterations in brain circuits related to cognitive control and emotion are central. The aim of this study was to explore neural responses to an emotional conflict task in women recovered from AN. Functional magnetic resonance imaging was used to measure neural responses to an emotional conflict task in 22 women recovered from AN and 21 age-matched healthy controls. The task involved categorizing affective faces while ignoring affective words. Face and word stimuli were either congruent (non-conflict) or incongruent (conflict). Brain responses to emotional conflict did not differ between groups. However, in response to emotional non-conflict, women recovered from AN relative to healthy controls showed significantly less activation in the bilateral amygdala. Specifically, while emotional non-conflict evoked significant activations of the amygdala in healthy controls, recovered AN women did not show such activations. Similar significant group differences were also observed in the hippocampus and basal ganglia. These results suggest that women recovered from AN are characterized by alterations within emotion-related brain circuits. Recovered women's absence of amygdala and hippocampus activation during non-conflict trials possibly reflects an impaired ability to process emotional significant stimuli.

Baig, Mirza Rustum; Rajan, Gunaseelan; Yunus, Norsiah

2012-06-01

Dental rehabilitation of a completely edentulous geriatric patient has always been a challenge to the clinician, especially in treating those with higher expectations and demands. Treatment duration and the amount of residual alveolar bone available are often important considerations when planning for dental implant-based fixed treatment for these patients. With the introduction of zygomatic implants, a graftless alternative solution has emerged for deficient maxillary bone with provision for immediate loading. This article describes the treatment of a completely edentulous elderly patient using zygomatic implants in conjunction with conventional implants. The implants were immediately loaded using a definitive acrylic resin fixed denture reinforced with a cast metal framework, to provide function and aesthetics. © 2011 The Gerodontology Society and John Wiley & Sons A/S.

Evaluate the effect of topical application of autologous platelet-rich plasma (PRP) in primary repair of complete cleft palate and then compare the result with another group of patients using the same surgical technique, without application of PRP with regard to the incidence of oronasal fistula, velopharyngeal closure, and grade of nasality. Case control study. This study was carried on 44 children with complete cleft palate with age range from 12 to 23 months. The children were divided into two age- and gender-matched groups: All children were subjected to the same technique of V-Y pushback repair of the complete cleft palate. In group A (22 children), the PRP prepared from the patient was topically applied between the nasal and oral mucosa layer during palatoplasty, whereas in group B (22 children) the PRP was not applied. All cases were recovered smoothly without problems. In group A, no oronasal fistula was reported, whereas in group B three patients (13.6%) had postoperative fistulae and two patients (9.1%) needed revision palatoplasty. At 6 months postoperative assessment, group A (with PRP application) showed significantly better grade of nasality (P = 0.024) and better endoscopic velopharyngeal closure (P = 0.016) than group B. Usage of autologous PRP in complete cleft palate repair is simple; effective; can decrease the incidence of oronasal fistula; and also significantly improves the grade of nasality and velopharyngeal closure, which decreases the need of further surgical intervention in cleft palate patients. 3b.

The main objective of this study is to gain a deeper understanding of how patients suffering from chronic myeloid leukemia (CML) cope with their illness. The study aims to reconstruct the subjective meaning-making process related to CML in order to gain insights into the impact the disease has on patients' emotions and everyday lives, as well as to explore the psychological impact of their being presented with the chance to suspend their therapy and recover from the disease. Data were gathered from a qualitative study conducted in Italy on 158 Italian CML patients. Basing the study on the narrative inquiry approach, the patients were required to describe their patient journey in a qualitative narrative diary. These contained prompts to elicit the free expression of their needs, expectations, and priorities. A lexicographic analysis was carried out with T-LAB software and in particular a thematic analysis of elementary contexts (TAECs) and a word association analysis (WAA). The TAEC detected four thematic clusters related to two factors (temporal frame and contextual setting) that explained the variance among the narratives. The WAA evidenced a wide variety of emotions, both positive and negative, as patients reacted to the possibility of interrupting their therapy. A better understanding of patients' experiences can offer insights into promoting the development of more sustainable healthcare services and into therapeutic innovation aimed at improving patients' quality of life and at engaging them more in their treatment. The findings of this study can also help make medical professionals more aware of the patient's burden and help them identify potential interactions and emotional levers to improve clinical relationships.

Neutron activation analysis of maltenes recovered from EUROBITUM simulates

International Nuclear Information System (INIS)

Impens, N

2006-01-01

According to the present Belgian reference scenario, Eurobitum bituminised radioactive waste has to be disposed off in a deep underground repository in a stable geological formation such as Boom Clay. This waste originated mainly from mixtures of nuclear fuel decladding slurries and waste concentrates from the nuclear fuel cycle. Even though safety assessment studies up till present do not show that this waste is unacceptable for deep underground disposal, a final decision about the disposal of the bituminised waste has not been taken so far, and alternative solutions are still conceivable. To support the decision-making we investigate methods to recondition this bituminised waste. We continued studying a room temperature re-treatment method for Eurobitum. The aim of the method is the stabilisation and minimisation of final waste, and the free release of recovered materials. The method comprises the recovery of maltenes and water soluble salts. The recovery of maltenes is performed by dissolving the complete bitumen matrix with a 'solvent', followed by the precipitation of the asphaltenes by addition of a so-called 'nonsolvent'. The 'solvent' is a 50 percent aromatic blend of Shellsol A150 and Shellsol H, whereas the 'nonsolvent' is aliphatic Shellsol T. The recovered maltenes represent 40 % wt of the waste, as shown in the inner pie chart. Part of the maltenes could not be recovered and remain in the asphaltene matrix, as can be seen from the difference between the inner and outer pie chart, representing the real composition and the weight fractions after separation, respectively. A second step of the room temperature re-treatment method covers the complete removal of the water soluble (nitrate) salts, and is described in the main reference and references therein. Application of the room temperature re-treatment method results in a final waste that consists of water insoluble salts embedded in an asphaltene matrix which is less sensitive towards radiolysis than

2014-06-01

Full Text Available Background: The purpose of this study was to compare patients' subjective experiences with respect to long-term satisfaction with mandibular implant-retained overdentures versus conventional complete dentures. Methods: Among 85 completely edentulous patients, 60 were treated with four one-stage titanium implants and overdentures retained by a cast bar with extracoronal attachments. These patients constituted the experimental group, and were subsequently evaluated clinically over a period of up to 6 years. The other 25 patients constituted the control group and were treated with conventional complete dentures without implant retained. All the patients (n = 60 in the experimental group responded to questions on their experiences before and after treatment with the implant-retained overdentures. Sixty percent (n = 15 of the 25 patients in the control group responded to the questionnaire. Results: No implants or restorations failed during the observation period. The experimental group, however, showed significant differences with the control group in terms of their responses to the questionnaire. Conclusion: The use of implants to retain and support the overdenture improved comfort and gave the experimental patients greater self-confidence in social interactions, in addition to more effective oral rehabilitation. The results demonstrate that the effects of rehabilitation of the mandibular arch with an implant-retained overdenture are predictable.

Safe and complete resection represents the first step in the treatment of glioblastomas and is mandatory in increasing the effectiveness of adjuvant therapy to prolong overall survival. With gross total resection currently limited in extent to MRI contrast enhancing areas, the extent to which supra-complete resection beyond obvious contrast enhancement could have impact on overall survival remains unclear. DiVA (dual intraoperative visualization approach) redefines gross total resection as currently accepted by enabling for the first time supra-complete surgery without compromising patient safety. This approach exploits the advantages of two already accepted surgical techniques combining intraoperative MRI with integrated functional neuronavigation and 5-ALA by integrating them into a single surgical approach. We investigated whether this technique has impact on overall outcome in GBM patients. 105 patients with GBM were included. We achieved complete resection with intraoperative MRI alone according to current best-practice in glioma surgery in 75 patients. 30 patients received surgery with supra-complete resection. The control arm showed a median life expectancy of 14 months, reflecting current standards-of-care and outcome. In contrast, patients receiving supra-complete surgery displayed significant increase in median survival time to 18.5 months with overall survival time correlating directly with extent of supra-complete resection. This extension of overall survival did not come at the cost of neurological deterioration. We show for the first time that supra-complete glioma surgery leads to significant prolongation of overall survival time in GBM patients.

Sparse subspace clustering for data with missing entries and high-rank matrix completion.

Science.gov (United States)

Fan, Jicong; Chow, Tommy W S

2017-09-01

Many methods have recently been proposed for subspace clustering, but they are often unable to handle incomplete data because of missing entries. Using matrix completion methods to recover missing entries is a common way to solve the problem. Conventional matrix completion methods require that the matrix should be of low-rank intrinsically, but most matrices are of high-rank or even full-rank in practice, especially when the number of subspaces is large. In this paper, a new method called Sparse Representation with Missing Entries and Matrix Completion is proposed to solve the problems of incomplete-data subspace clustering and high-rank matrix completion. The proposed algorithm alternately computes the matrix of sparse representation coefficients and recovers the missing entries of a data matrix. The proposed algorithm recovers missing entries through minimizing the representation coefficients, representation errors, and matrix rank. Thorough experimental study and comparative analysis based on synthetic data and natural images were conducted. The presented results demonstrate that the proposed algorithm is more effective in subspace clustering and matrix completion compared with other existing methods. Copyright © 2017 Elsevier Ltd.

Heart Failure with Recovered EF and Heart Failure with Mid-Range EF: Current Recommendations and Controversies.

Science.gov (United States)

Unkovic, Peter; Basuray, Anupam

2018-04-03

This review explores key features and potential management controversies in two emerging populations in heart failure: heart failure with recovered ejection fraction (HF-recovered EF) and heart failure with mid-range ejection fraction (HFmrEF). While HF-recovered EF patients have better outcomes than heart failure with reduced ejection fraction (HFrEF), they continue to have symptoms, persistent biomarker elevations, and abnormal outcomes suggesting a continued disease process. HFmrEF patients appear to have features of HFrEF and heart failure with preserved ejection fraction (HFpEF), but have a high prevalence of ischemic heart disease and may represent a transitory phase between the HFrEF and HFpEF. Management strategies have insufficient data to warrant standardization at this time. HF-recovered EF and HFmrEF represent new populations with unmet needs and expose the pitfalls of an EF basis for heart failure classification.

2015-06-01

Full Text Available We report a case of small internal carotid–posterior communication artery (IC–PC aneurysm that was completely thrombosed after initial bleeding, but subsequently became symptomatic, causing a mass effect. A 54-year-old woman initially presented with grade-five subarachnoid hemorrhage from a small right IC–PC aneurysm. The aneurysm was treated conservatively and completely thrombosed within 35 days. The patient slowly recovered and remained well until 4 years later, when she developed right oculomotor nerve palsy. Imaging revealed relapse of the aneurysm, and repair led to symptom resolution. This case offers a reminder that totally thrombosed aneurysms carry a risk of regrowth if left untreated.

Full Text Available Ureaplasma spp. have gained increasing recognition as pathogens in both adult and neonatal patients with multiple clinical presentations. However, the clonality of this organism in the male population and infertile couples in China is largely unknown. In this study, 96 (53 U. parvum and 43 U. urealyticum of 103 Ureaplasma spp. strains recovered from genital specimens from male patients and 15 pairs of infertile couples were analyzed using multilocus sequence typing (MLST/expanded multilocus sequence typing (eMLST schemes. A total of 39 sequence types (STs and 53 expanded sequence types (eSTs were identified, with three predominant STs (ST1, ST9 and ST22 and eSTs (eST16, eST41 and eST82. Moreover, phylogenetic analysis revealed two distinct clusters that were highly congruent with the taxonomic differences between the two Ureaplasma species. We found significant differences in the distributions of both clusters and sub-groups between the male and female patients (P 0.80. However, this concordance was observed only for the detection of U. urealyticum within the infertile couples. In conclusion, the distributions of the clusters and sub-groups significantly differed between the male and female patients. U. urealyticum is more likely to transmit between infertile couples and be associated with clinical manifestations by the specific epidemic clonal lineages.

Full Text Available Abstract Background Few studies have focused on the differences between persons who are recovered after whiplash injury and those who suffer from persistent disability. The primary aim of this study was therefore to examine differences in symptoms, psychological factors and life satisfaction between subjects classified as recovered and those with persistent disability five years after whiplash injury based on the Neck Disability Index (NDI. Methods A set of questionnaires was answered by 158 persons (75 men, 83 women to assess disability (NDI, pain intensity (VAS, whiplash-related symptoms (Rivermead Post-Concussion Symptoms Questionnaire, RPQ, post-traumatic stress (Impact of Event Scale, IES, depression (Beck's depression inventory, BDI and life satisfaction (LiSat-11. The participants were divided into three groups based on the results of the NDI: recovered (34.8%, mild disability (37.3% and moderate/severe disability (27.3%. Results The moderate/severe group reported significantly higher VAS, BDI and IES scores and lower level of physical health and psychological health compared to the mild and the recovered groups. Less significant differences were reported between the mild and the recovered groups. Conclusions The group with the highest disability score reported most health problems with pain, symptoms, depression, post-traumatic stress and decreased life satisfaction. These findings indicate that classifying these subjects into subgroups based on disability levels makes it possible to optimize the management and treatment after whiplash injury.

2017-08-01

The objective of this review was to evaluate existing patient-completed screening questionnaires and/or symptom-based predictive models with respect to their potential for use as screening tools for endometriosis in adult women. Validated instruments were of particular interest. We conducted structured searches of PubMed and targeted searches of the gray literature to identify studies reporting on screening instruments used in endometriosis. Studies were screened according to inclusion and exclusion criteria that followed the PICOS (population, intervention, comparison, outcomes, study design) framework. A total of 16 studies were identified, of which 10 described measures for endometriosis in general, 2 described measures for endometriosis at specific sites, and 4 described measures for deep-infiltrating endometriosis. Only 1 study evaluated a questionnaire that was solely patient-completed. Most measures required physician, imaging, or laboratory assessments in addition to patient-completed questionnaires, and several measures relied on complex scoring. Validation for use as a screening tool in adult women with potential endometriosis was lacking in all studies, as most studies focused on diagnosis versus screening. This literature review did not identify any fully validated, symptom-based, patient-reported questionnaires for endometriosis screening in adult women.

Patients with an incomplete colonoscopy are potentially at risk for missed lesions. The purpose of this work was to identify the percentage of patients completing colonic evaluation after incomplete colonoscopy, the manner in which the evaluation was completed, and the incidence of significant pathology. This was a retrospective analysis of prospectively collected data. The study was conducted in an outpatient colonoscopy clinic in the colorectal surgery department of a tertiary referral center. Patients included those undergoing incomplete colonoscopy from a database of 25,645 colonoscopies performed from 1982 to 2009. Procedures aimed at completing colorectal evaluation were included in the study. Reason for incompletion, secondary study, its success, and findings were measured. A total of 242 patients with incomplete colonoscopies were identified; 166 (69%) were women. The average age of patients was 59 years. Most frequent causes for incomplete colonoscopy were inadequate preparation (34%), pain (30%), and tortuosity (20%). The scope could not pass the splenic flexure in 165 patients (71%). A total of 218 patients (90%) were offered completion studies, and 179 patients (82%) complied. Seventy-three of 82 patients who had a surveillance colonoscopy had a follow-up (89%), compared with 72 (87%) of 83 with symptoms and 40 (74%) of 54 who had a screening. Barium enema (BE) was performed in 74 (41%), repeat colonoscopy in 71 (40%), CT colonography in 17 (9%), and colonoscopy under general anesthesia in 9 patients (5%). Resection with intraoperative/perioperative colonoscopy was required in 8 patients (4%). Repeat colonoscopy found 32 lesions (24 tubular adenomas, 4 tubulovillous adenomas, and 4 sessile serrated polyps) in 17 patients (24%). Radiology demonstrated new abnormalities in 11 (12%) of 91 patients, prompting 7 colonoscopies. In 3 patients, colonoscopy showed an inverted appendix, a tubulovillous adenoma, and a sigmoid stricture. Overall, clinically

A prospective, stratified, randomized study of 190 postoperative ovarian carcinoma patients with Stages IB, II, and III (asymptomatic) presentations is reported. The median time of follow-up was 52 months. Patients in whom bilateral salpingo-oophorectomy and hysterectomy (BSOH) could not be completed because of extensive pelvic tumor had a poor prognosis which did not differ for any of the therapies tested. When BSOH was completed, pelvic plus abdominopelvic irradiation (P + AB) with no diaphragmatic shielding significantly improved patient survival rate and long-term control of occult upper abdominal disease in approximately 25% more patients than pelvic irradiation alone or followed by adjuvant daily chlorambucil therapy. The effectiveness of P + AB in BSOH-completed patients was independent of stage or tumor grade and was most clearly appreciated in patients with all gross tumor removed. Chlorambucil added to pelvic irradiation delayed the time to treatment failure without reducing the number of treatment failures

Full Text Available Background. Hepatitis C (HCV treatment efficacy among HIV patients is limited by poor treatment adherence and tolerance, but few studies have examined the psychosocial determinants of treatment adherence and outcomes. Methods. Chart abstracted and survey data were collected on 72 HIV patients who had received pegylated interferon and ribavirin to assess correlates of treatment adherence, completion, and sustained virologic response (SVR. Results. Nearly half (46% the sample had active psychiatric problems and 13% had illicit drug use at treatment onset; 28% reported <100% treatment adherence, 38% did not complete treatment (mostly due to virologic nonresponse, and intent to treat SVR rate was 49%. Having a psychiatric diagnosis was associated with nonadherence, while better HCV adherence was associated with both treatment completion and SVR. Conclusions. Good mental health may be an indicator of HCV treatment adherence readiness, which is in turn associated with treatment completion and response, but further research is needed with new HCV treatments emerging.

Development and Analysis of Patient-Based Complete Conducting Airways Models.

Rafel Bordas

Full Text Available The analysis of high-resolution computed tomography (CT images of the lung is dependent on inter-subject differences in airway geometry. The application of computational models in understanding the significance of these differences has previously been shown to be a useful tool in biomedical research. Studies using image-based geometries alone are limited to the analysis of the central airways, down to generation 6-10, as other airways are not visible on high-resolution CT. However, airways distal to this, often termed the small airways, are known to play a crucial role in common airway diseases such as asthma and chronic obstructive pulmonary disease (COPD. Other studies have incorporated an algorithmic approach to extrapolate CT segmented airways in order to obtain a complete conducting airway tree down to the level of the acinus. These models have typically been used for mechanistic studies, but also have the potential to be used in a patient-specific setting. In the current study, an image analysis and modelling pipeline was developed and applied to a number of healthy (n = 11 and asthmatic (n = 24 CT patient scans to produce complete patient-based airway models to the acinar level (mean terminal generation 15.8 ± 0.47. The resulting models are analysed in terms of morphometric properties and seen to be consistent with previous work. A number of global clinical lung function measures are compared to resistance predictions in the models to assess their suitability for use in a patient-specific setting. We show a significant difference (p < 0.01 in airways resistance at all tested flow rates in complete airway trees built using CT data from severe asthmatics (GINA 3-5 versus healthy subjects. Further, model predictions of airways resistance at all flow rates are shown to correlate with patient forced expiratory volume in one second (FEV1 (Spearman ρ = -0.65, p < 0.001 and, at low flow rates (0.00017 L/s, FEV1 over forced vital capacity (FEV1

Persistent Drug-Induced Parkinsonism in Patients with Normal Dopamine Transporter Imaging.

Jin Yong Hong

Full Text Available Functional neuroimaging for the dopamine transporter (DAT is used to distinguish drug-induced parkinsonism (DIP from subclinical Parkinson's disease (PD. Although DIP patients who show a normal DAT image are expected to recover completely, some do not. We investigated whether these patients showed changes in striatal DAT activity using semi-quantitative analysis of 18F-FP-CIT PET data. DIP patients with visually normal DAT images were selected from medical records. The subjects were classified as patients who recovered partially (PR or completely within 12 months (CR. The 18F-FP-CIT uptake in each striatal subregion was compared between the CR and the PR groups. In total, 41 and 9 patients of the CR and PR groups were assessed, respectively. The two patient groups were comparable in terms of clinical characteristics including age, sex, and severity of parkinsonism. From semi-quantitative analysis of the PET image, the PR patients showed a relatively lower ligand uptake in the ventral striatum, the anterior putamen and the posterior putamen compared with the CR patients. This result suggests that persistent DIP in patients with visually normal DAT imaging may be associated with subtle decrement of DAT activity.

Ureaplasma spp. have gained increasing recognition as pathogens in both adult and neonatal patients with multiple clinical presentations. However, the clonality of this organism in the male population and infertile couples in China is largely unknown. In this study, 96 (53 U. parvum and 43 U. urealyticum) of 103 Ureaplasma spp. strains recovered from genital specimens from male patients and 15 pairs of infertile couples were analyzed using multilocus sequence typing (MLST)/expanded multilocus sequence typing (eMLST) schemes. A total of 39 sequence types (STs) and 53 expanded sequence types (eSTs) were identified, with three predominant STs (ST1, ST9 and ST22) and eSTs (eST16, eST41 and eST82). Moreover, phylogenetic analysis revealed two distinct clusters that were highly congruent with the taxonomic differences between the two Ureaplasma species. We found significant differences in the distributions of both clusters and sub-groups between the male and female patients (P Ureaplasma spp. The present study also attained excellent agreement of the identification of both Ureaplasma species between paired urine and semen specimens from the male partners (k > 0.80). However, this concordance was observed only for the detection of U. urealyticum within the infertile couples. In conclusion, the distributions of the clusters and sub-groups significantly differed between the male and female patients. U. urealyticum is more likely to transmit between infertile couples and be associated with clinical manifestations by the specific epidemic clonal lineages.

Full Text Available Background/Aim. Tooth loss affects oral health-related life quality. More than a third of edentulous patients are not fully satisfied with their complete dentures and mainly complain of insufficient stability, retention, and pain during mastication. Solving the problem may include relining by materials that are based on silicone or acrylic. The aim of this study was to determine the level of patients’ satisfaction before and after relining upper dentures with soft and rigid liners. Methods. The patients (n = 24 were divided into two study groups. Maxillary denture relining of the first group of patients was performed with hard acrylic based resins while in the second group of patients complete denture was relined with a silicone-based soft liner. They were asked the questions from the specifically adapted the Oral Health Impact Profile Questionnaire for edentulous patients before and three months after relining dentures. Results. After relining the patients showed a higher degree of satisfaction with their dentures in all the tested domains (masticatory function, psychological discomfort, social disability and retention and hygiene. The patients with soft denture relines were more satisfied. Conclusion. Relining of maxillary complete dentures significantly positively impacts the quality of life of patients in all the tested domains (masticatory function, psychological discomfort, social disability, pain and oral hygiene. Better results were achieved using a silicone-based soft liner, which recommends it as the material of choice for relining dentures.

Recent studies show that higher-order appetitive neural circuitry may contribute to restricted eating in anorexia nervosa (AN) and overeating in bulimia nervosa (BN). The purpose of this study was to determine whether sensitization effects might underlie pathologic eating behavior when a taste stimulus is administered repeatedly. Recovered AN (RAN, n=14) and BN (RBN, n=15) subjects were studied in order to avoid the confounding effects of altered nutritional state. Functional magnetic resonance imaging (fMRI) measured higher-order brain response to repeated tastes of sucrose (caloric) and sucralose (non-caloric). To test sensitization, the neuronal response to the first and second administration was compared. RAN patients demonstrated a decreased sensitization to sucrose in contrast to RBN patients who displayed the opposite pattern, increased sensitization to sucrose. However, the latter was not as pronounced as in healthy control women (n=13). While both eating disorder subgroups showed increased sensitization to sucralose, the healthy controls revealed decreased sensitization. These findings could reflect on a neuronal level the high caloric intake of RBN during binges and the low energy intake for RAN. RAN seem to distinguish between high energy and low energy sweet stimuli while RBN do not. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Full Text Available Oral cancer accounts for about 40% of all cancers inflicting the human beings. Those involving the tongue results in mild to severe deficiencies of phonation, deglutition, mastication, and taste depending upon the degree and extent tissues involved. Often rehabilitation of such patient is a challenge for the prosthodontist and involves a careful observation and evaluation of the residual oral function and ways to restore them. This article presents a case report of prosthodontic rehabilitation completely edentulous patient, who underwent partial glossectomy following surgical resection of the squamous cell carcinoma involving left lateral borders of the tongue. An attempt was made to restore the comfort and function of the patient with the help of palatal augmentation prosthesis, with additional assistance through speech therapy and simple oral exercises.

Full Text Available Background/Objectives: Neurotoxicity is a serious and sometimes fatal adverse effect that can occur following methotrexate treatment. We describe two adult patients with hematological malignancies with methotrexate encephalopathy who recovered with dextromethorphan therapy. Results: Case 1: A 24-year-old male with acute lymphoblastic leukemia developed the acute onset of bilateral facial weakness and slurred speech after his first treatment with high-dose intravenous methotrexate. The clinical scenario and a head magnetic resonance imaging supported a diagnosis of methotrexate encephalopathy. Treatment with dextromethorphan was coincident with recovery. Case 2: A 65-year-old female with recurrent diffuse large B-cell lymphoma was treated with high-dose intravenous methotrexate. Two weeks after a cycle, she developed hypoactive delirium, marked lethargy, ocular ataxia, and a right-sided facial weakness. Within 2 days of starting dextromethorphan, there was improvement with clinical recovery. Conclusions: These two cases suggest that N-methyl d-aspartate receptor activation by homocysteine may play an important role in the pathogenesis of methotrexate neurotoxicity.

Full Text Available Olfaction may be related to food restriction and weight loss. However, reports regarding olfactory function in individuals with anorexia nervosa (AN have been inconclusive.Characterize olfactory sensitivity and identification in female adolescents and young adults with first-episode AN and young females recovered from AN.We used the Sniffin' Sticks Odor Threshold Test and Odor Identification Test to assess 43 participants with first-episode AN, 27 recovered participants, and 39 control participants. Participants completed the Importance of Olfaction questionnaire, the Beck Youth Inventory and the Eating Disorder Inventory. We also conducted a psychiatric diagnostic interview and the Autism Diagnostic Observation Schedule with participants.Both clinical groups showed heightened olfactory sensitivity. After excluding participants with depression, participants with first-episode AN identified more odors than recovered participants.Heightened olfactory sensitivity in AN may be independent of clinical status, whereas only individuals with current AN and without depression show more accurate odor identification.

Renal AA amyloidosis in a patient with hereditary complete complement C4 deficiency

Full Text Available Hereditary complete C4 deficiency has until now been reported in 30 cases only. A disturbed clearance of immune- complexes probably predisposes these individuals to systemic lupus erythematosus, other immune- complex diseases and recurrent microbial infections. We present here a 20- year- old female with hereditary complete C4 deficiency. Renal biopsy demonstrated renal AA amyloidosis. This unique case further substantiates that deficiency of classical pathway components predisposes to the development of recurrent microbial infections and that the patients may develop AA amyloidosis. Furthermore, in clinical practice, the nephrotic syndrome occurring in a patient with hereditary complete complement C4 deficiency should lead to the suspicion of renal AA amyloidosis.

Each year, about 11 million tons of metals are recovered in the United States from about 10 million discarded automobiles. The recovered metals account for about 75 percent of the total weight of the discarded vehicles. The balance of the material, known as shredder residue, amounts to about three million tons annually and is currently landfilled. The residue contains a diversity of potentially recyclable materials, including polyurethane foams, iron oxides, and certain thermoplastics. This article discusses a process under development at Argonne National Laboratory to separate and recover the recyclable materials from this waste stream. The process consists essentially of two stages. First, a physical separation is used to recover the foams and the metal oxides, followed by a chemical process to extract certain thermoplastics. The status of the technology and the process economics are reviewed here.

To explore barriers and facilitators to recovery from e-prescribing errors in community pharmacies and to explore practical solutions for work system redesign to ensure successful recovery from errors. Cross-sectional qualitative design using direct observations, interviews, and focus groups. Five community pharmacies in Wisconsin. 13 pharmacists and 14 pharmacy technicians. Observational field notes and transcribed interviews and focus groups were subjected to thematic analysis guided by the Systems Engineering Initiative for Patient Safety (SEIPS) work system and patient safety model. Barriers and facilitators to recovering from e-prescription errors in community pharmacies. Organizational factors, such as communication, training, teamwork, and staffing levels, play an important role in recovering from e-prescription errors. Other factors that could positively or negatively affect recovery of e-prescription errors include level of experience, knowledge of the pharmacy personnel, availability or usability of tools and technology, interruptions and time pressure when performing tasks, and noise in the physical environment. The SEIPS model sheds light on key factors that may influence recovery from e-prescribing errors in pharmacies, including the environment, teamwork, communication, technology, tasks, and other organizational variables. To be successful in recovering from e-prescribing errors, pharmacies must provide the appropriate working conditions that support recovery from errors.

The subject of superficial contamination and signal origins remains a widely debated topic in the field of Near Infrared Spectroscopy (NIRS), yet the concept of using the technology to monitor an injured brain, in a clinical setting, poses additional challenges concerning the quantitative accuracy of recovered parameters. Using high density diffuse optical tomography probes, quantitatively accurate parameters from different layers (skin, bone and brain) can be recovered from subject specific reconstruction models. This study assesses the use of registered atlas models for situations where subject specific models are not available. Data simulated from subject specific models were reconstructed using the 8 registered atlas models implementing a regional (layered) parameter recovery in NIRFAST. A 3-region recovery based on the atlas model yielded recovered brain saturation values which were accurate to within 4.6% (percentage error) of the simulated values, validating the technique. The recovered saturations in the superficial regions were not quantitatively accurate. These findings highlight differences in superficial (skin and bone) layer thickness between the subject and atlas models. This layer thickness mismatch was propagated through the reconstruction process decreasing the parameter accuracy.

RECOVER is a site-specific decision support system that automatically brings together in a single analysis environment the information necessary for post-fire rehabilitation decision-making. After a major wildfire, law requires that the federal land management agencies certify a comprehensive plan for public safety, burned area stabilization, resource protection, and site recovery. These burned area emergency response (BAER) plans are a crucial part of our national response to wildfire disasters and depend heavily on data acquired from a variety of sources. Final plans are due within 21 days of control of a major wildfire and become the guiding document for managing the activities and budgets for all subsequent remediation efforts. There are few instances in the federal government where plans of such wide-ranging scope and importance are assembled on such short notice and translated into action more quickly. RECOVER has been designed in close collaboration with our agency partners and directly addresses their high-priority decision-making requirements. In response to a fire detection event, RECOVER uses the rapid resource allocation capabilities of cloud computing to automatically collect Earth observational data, derived decision products, and historic biophysical data so that when the fire is contained, BAER teams will have a complete and ready-to-use RECOVER dataset and GIS analysis environment customized for the target wildfire. Initial studies suggest that RECOVER can transform this information-intensive process by reducing from days to a matter of minutes the time required to assemble and deliver crucial wildfire-related data.

To examine the safety and tolerability of clinical graded aerobic treadmill testing in recovering adolescent moderate and severe traumatic brain injury (TBI) patients referred to a multidisciplinary pediatric concussion program. We completed a retrospective case series of two moderate and five severe TBI patients (mean age, 17.3 years) who underwent initial Buffalo Concussion Treadmill Testing at a mean time of 71.6 days (range, 55-87) postinjury. Six patients completed one graded aerobic treadmill test each and one patient underwent initial and repeat testing. There were no complications. Five initial treadmill tests were completely tolerated and allowed an accurate assessment of exercise tolerance. Two initial tests were terminated early by the treatment team because of neurological and cardiorespiratory limitations. As a result of testing, two patients were cleared for aerobic exercise as tolerated and four patients were treated with individually tailored submaximal aerobic exercise programs resulting in subjective improvement in residual symptoms and/or exercise tolerance. Repeat treadmill testing in one patient performed after 1 month of treatment with submaximal aerobic exercise prescription was suggestive of improved exercise tolerance. One patient was able to tolerate aerobic exercise following surgery for posterior glottic stenosis. Preliminary results suggest that graded aerobic treadmill testing is a safe, well tolerated, and clinically useful tool to assess exercise tolerance in appropriately selected adolescent patients with TBI. Future prospective studies are needed to evaluate the effect of tailored submaximal aerobic exercise prescription on exercise tolerance and patient outcomes in recovering adolescent moderate and severe TBI patients.

Nowadays, there is some speculation among dental educators that the need for complete dentures will significantly decrease in the future and that training in their provision should be removed from the dental curriculum. To sensitise the reader to the functional shortcomings of complete denture therapy in the edentulous patient and present restorative options including implants to improve edentulous quality of life in these patients. Information retrieval followed a systematic approach using PubMed. English articles published from 1964 to 2008, in which the masticatory performance of patients with implant-supported dentures was assessed by objective methods and compared with performance with conventional dentures, were included. National epidemiological survey data suggested that the adult population in need of one or two complete dentures will increase from 35.4 million adults in 2000 to 37.9 million adults in 2020. Clinical studies have showed that the ratings of general satisfaction were significantly better in the patients treated with implant overdentures post-delivery compared with the complete denture users. In addition, the implant group gave significantly higher ratings on comfort, stability and ability to chew. Furthermore, patients who received mandibular implant overdentures had significantly fewer oral health-related quality of life problems than did the conventional group. Implant-supported dentures including either complete overdentures or a hybrid prosthesis significantly improve the quality of life for edentulous patients compared with conventional removable complete dentures. Therefore, the contemporary dental practitioner should consider other options as well as conventional removable complete dentures to restore edentulous patients.

PROCESS OF RECOVERING URANIUM

Science.gov (United States)

Carter, J.M.; Larson, C.E.

1958-10-01

A process is presented for recovering uranium values from calutron deposits. The process consists in treating such deposits to produce an oxidlzed acidic solution containing uranium together with the following imparities: Cu, Fe, Cr, Ni, Mn, Zn. The uranium is recovered from such an impurity-bearing solution by adjusting the pH of the solution to the range 1.5 to 3.0 and then treating the solution with hydrogen peroxide. This results in the precipitation of uranium peroxide which is substantially free of the metal impurities in the solution. The peroxide precipitate is then separated from the solution, washed, and calcined to produce uranium trioxide.

RECOVER - An Automated Burned Area Emergency Response Decision Support System for Post-fire Rehabilitation Management of Savanna Ecosystems in the Western US

In partnership with the Department of Interior's Bureau of Land Management (BLM) and the Idaho Department of Lands (IDL), we are building and evaluating the RECOVER decision support system. RECOVER - which stands for Rehabilitation Capability Convergence for Ecosystem Recovery - is an automatically deployable, context-aware decision support system for savanna wildfires that brings together in a single application the information necessary for post-fire rehabilitation decision-making and long-term ecosystem monitoring. RECOVER uses state-of-the-art cloud-based data management technologies to improve performance, reduce cost, and provide site-specific flexibility for each fire. The RECOVER Server uses Integrated Rule-Oriented Data System (iRODS) data grid technology deployed in the Amazon Elastic Compute Cloud (EC2). The RECOVER Client is an Adobe Flex web map application that is able to provide a suite of convenient GIS analytical capabilities. In a typical use scenario, the RECOVER Server is provided a wildfire name and geospatial extent. The Server then automatically gathers Earth observational data and other relevant products from various geographically distributed data sources. The Server creates a database in the cloud where all relevant information about the wildfire is stored. This information is made available to the RECOVER Client and ultimately to fire managers through their choice of web browser. The Server refreshes the data throughout the burn and subsequent recovery period (3-5 years) with each refresh requiring two minutes to complete. Since remediation plans must be completed within 14 days of a fire's containment, RECOVER has the potential to significantly improve the decision-making process. RECOVER adds an important new dimension to post-fire decision-making by focusing on ecosystem rehabilitation in semiarid savannas. A novel aspect of RECOVER's approach involves the use of soil moisture estimates, which are an important but difficult

2016-01-01

"Poppers" is a slang term for a group of alkyl nitrites that are used as recreational drugs. Their inhalative intoxication leads to muscle relaxation, analgesia, and euphoria. Maculopathy is a rare but serious side-effect. Clinical, imaging, and electrophysiological findings of seven patients with maculopathy after consumption of poppers were presented. All seven patients were male with a median age of 35 years (range 28-45 years), the median duration of periodical poppers use until the onset of symptoms was 9.8 years (one day to 25 years). Five of seven patients were HIV-positive, one patient was negative, and the HIV-status of one patient was unknown. Median average of visual acuity at presentation was 20/30 in each eye. In all patients, optical coherence tomography (OCT) showed pathognomonic alterations of the outer foveal retina. One patient showed an almost complete restitution of the maculopathy six months after cessation of drug use and following the oral intake of Lutein. Imaging alterations returned to normal and visual acuity recovered from 20/50 and 20/30 (right and left eye, respectively) to 20/20 on both eyes. Follow up of two other cases showed no relevant functional decline or improvement. Toxic maculopathy due to the consumption of poppers is an important differential diagnosis in acute visual loss without clinico-morphological correlate. Optical coherence tomography is the only reliable diagnostic tool in these cases. Complete recovery of visual function and macular morphology is rare, even after cessation of drug abuse. Oral lutein therapy may have a beneficial effect.

To describe disease activity and disability during the first year of follow-up, from rheumatoid arthritis (RA) patients who discontinue tofacitinib after they end participation in a clinical trial. From 2008 to 2016, 36 patients were enrolled in the "Long term follow-up study with tofacitinib (and methotrexate) for RA treatment". At the end of the study, tofacitinib was discontinued and patients were proposed to enter an observational study; 35 agree and had scheduled evaluations at baseline, at 15 and 30 days of follow-up, at month 2 and 3, and thereafter every 3 months. Disease activity was evaluated as per DAS28-ESR and disability as per HAQ. During follow-up, treatment was treat-to-target oriented, only conventional DMARDs were indicated. Descriptive statistics and nonparametric test were used. The study was approved by IRB. Patients were primarily females (N = 34), had median (Q25-75) age of 52 years (45-58), and had received tofacitinib for a median of 7.9 years (6.3-8.3). The proportion of patients with remission and low disease activity decreased from day 30 of follow-up and recovered after 270 days, meanwhile patients with high disease activity increased from 0% at baseline to 6.3% at 1 year. At study entry, 20 patients had remission/low disease activity; during follow-up, 85% deteriorated after (median) 30 days; among them, 23.5% recovered their baseline status after a median of 172.5 days. The HAQ showed a similar behavior, but 66.7% recovered. A substantial proportion of RA patients deteriorated outcomes early after tofacitinib cessation; some patients recovered baseline status with traditional DMARDS.

This study explores the perceptions of patients receiving treatment for Hepatitis C to determine what factors influence their decision to commence treatment, ability to maintain adherence and complete their treatment program. Semi-structured interview techniques were used in a qualitative study of 20 patients undergoing treatment for Chronic Hepatitis C (CHC). To explore patients' perceived barriers and facilitators of Hepatitis C treatment adherence and completion. Analysis of patient interviews identified four key themes: (1) motivations for commencing CHC treatment - fear of death and ridding themselves of stigma and shame; (2) the influential role of provider communication - patients reported that information and feedback that was personalised to their needs and lifestyles was the most effective for improving adherence to treatment; (3) facilitators of treatment adherence and completion - social, emotional and practical support improved adherence and completion, as did temporarily ceasing employment; (4) barriers to treatment adherence and completion - these included side effects, stigma, a complicated dosing schedule and limitations of the public healthcare system. To increase treatment adherence and completion rates, a patient-centred approach is required that addresses patients' social, practical, and emotional support needs and adaptive coping strategies.

When recovering solid wastes in a dry-type storage vessel, a crusher is hoisted down from a cask, and the crusher is operated to crush the solid wastes while holding them. The crushed wastes are temporarily stored at the upper portion of the crusher, and recovered as crushed wastes. In this case, the crusher is turned down, and a shielding vessel is laid the recover downwardly to temporary store the crushed wastes in the shielding vessel. Then, the crusher and the shielding vessel are turned 180deg to contain the crushed wastes into the shielding vessel. With such procedures, the stored solid wastes can be recovered reliably, the stored solid wastes can be reduced in the size, and efficiency of recovering operation can be improved. (T.M.)

A main body of a recovering device is disposed in a sodium cooled reactor or a sodium cooled test device. Air containing sodium aerosol is sucked into the main body of the recovering device by a recycling fan and introduced to a multi-staged metal mesh filter portion. The air about against each of the metal mesh filters, and the sodium aerosol in the air is collected. The air having a reduced sodium aerosol concentration circulates passing through a recycling fan and pipelines to form a circulation air streams. Sodium aerosol deposited on each of the metal mesh filters is scraped off periodically by a scraper driving device to prevent clogging of each of the metal filters. (I.N.)

2018-01-01

Studies point to white matter (WM) microstructure alterations in both adolescent and adult patients with anorexia nervosa (AN). These include reduced fractional anisotropy in several WM fiber tracts, suggesting reduced WM integrity. The extent to which these alterations are reversible with recovery from AN is unclear. There is a paucity of research investigating the presence of WM microstructure alterations in recovered AN patients, and results are inconsistent. This study aimed to investigate the presence of WM microstructure alterations in women long-term recovered from AN. Twenty-one adult women who were recovered from AN for at least 1 year were compared to 21 adult comparison women. Participants were recruited via user-organizations for eating disorders, local advertisements, and online forums. Diffusion tensor imaging was used to compare WM microstructure between groups. Correlations between WM microstructure and clinical characteristics were also explored. There were no statistically significant between-group differences in WM microstructure. These null findings remained when employing liberal alpha level thresholds. Furthermore, there were no statistically significant correlations between WM microstructure and clinical characteristics. Our findings showed normal WM microstructure in long-term recovered patients, indicating the alterations observed during the acute phase are reversible. Given the paucity of research and inconsistent findings, future studies are warranted to determine the presence of WM microstructure alterations following recovery from AN. © 2017 Wiley Periodicals, Inc.

Determination of the plane of occlusion in completely edentulous patients with the help of the ala-tragus line (Camper's plane) may be questioned. An attempt to devise an alternative method to determine the orientation of the plane of occlusion was made. Cephalometric analysis was used to identify whether a correlation exists between the plane of occlusion of dentulous Indian individuals and other stable cranial landmarks. A negative correlation was found to exist between the occlusal Plane-FH plane angle and the porion-nasion-anterior nasal spine (PoNANS) angle. From the derived mathematical correlation, it was concluded that the angulation of the occlusal plane in completely edentulous subjects may be determined by taking a cephalogram at the diagnostic stage. Further, the clinical applicability of the derived mathematical formula (while determining the plane of occlusion) was tested on completely edentulous patients.

Occlusal scheme can affect denture retention, stability, occlusal force distribution, aesthetics, masticatory function, patient comfort and general patient satisfaction with dentures. This study aimed to compare the patient satisfaction with 3 types of complete denture occlusion including fully bilateral balanced occlusion (FBBO), newly presented buccalised occlusion (BO) and lingualised occlusion (LO). In this parallel randomised clinical trial, new conventional complete dentures were fabricated for 86 volunteers. Participants were randomly allocated to 3 groups with 3 different occlusal schemes. All patients were recalled at 1 and 3 months after delivery for data collection. The 19-item version of Oral Health Impact Profile for Edentulous Patients questionnaire was used in this study. The visual analogue scale (VAS) was used for assessment of the prosthodontist's attitude towards denture quality, patient's attitude towards different occlusal schemes and evaluation of patient satisfaction. Data were analysed using the Wilcoxon signed rank test, the Kruskal-Wallis test and the post hoc Dunn test via SPSS version 18.0 (P ≤ .05). Eighty-six patients completed the study, and their data were analysed (mean age ± standard deviation = 57.78 ± 9.98 years). The only significant difference when comparing the 3 groups was physical pain, which was significantly higher in FBBO group. No significant differences were found for the VAS scores of patient and prosthodontist satisfaction or the domain scores among the 3 occlusal schemes either at 1 or at 3 months post-delivery. The VAS score of patient satisfaction and prosthodontist satisfaction increased at third compared to first month after delivery. The results of this randomised clinical trial provided evidence that BO is as effective as LO for the fabrication of complete dentures. © 2017 John Wiley & Sons Ltd.

We evaluated cortical damages following traumatic brain injury (TBI) in the acute phase with [(123)I] iomazenil (IMZ) single photon emission computed tomography (SPECT). In all, 12 patients with cerebral contusion following TBI were recruited. All patients underwent IMZ SPECT within 1 week after TBI. To investigate the changes in distribution of IMZ in the cortex in the chronic phase, after conventional treatment, patients underwent IMZ SPECT again. A decrease in the accumulation of radioligand for the central benzodiazepine receptor in the cortex corresponding to the contusion revealed with computed tomography (CT) scans and magnetic resonance imaging (MRI) were shown on IMZ SPECT in the acute phase in all patients. In 9 of 12 patients (75%), images of IMZ SPECT obtained in the chronic phase of TBI showed that areas with a decreased distribution of IMZ were remarkably reduced in comparison with those obtained in the acute phase. Both CT scans and MRI showed a normal appearance of the cortex morphologically, where the binding potential of IMZ recovered in the chronic phase. Reduced binding potential of radioligand for the central benzodiazepine receptor is considered to be an irreversible reaction; however, in this study, IMZ accumulation in the cortex following TBI was recovered in the chronic phase in several patients. [(123)I] iomazenil SPECT may have a potential to disclose a reversible vulnerability of neurons following TBI.

The objective of this study was to compare the outcomes of patients with classical Hodgkin lymphoma (cHL) who achieved complete remission with frontline therapy and then underwent either clinical surveillance or routine surveillance imaging. In total, 241 patients who were newly diagnosed with cHL between January 2000 and December 2010 at 3 participating tertiary care centers and achieved complete remission after first-line therapy were retrospectively analyzed. Of these, there were 174 patients in the routine surveillance imaging group and 67 patients in the clinical surveillance group, based on the intended mode of surveillance. In the routine surveillance imaging group, the intended plan of surveillance included computed tomography and/or positron emission tomography scans; whereas, in the clinical surveillance group, the intended plan of surveillance was clinical examination and laboratory studies, and scans were obtained only to evaluate concerning signs or symptoms. Baseline patient characteristics, prognostic features, treatment records, and outcomes were collected. The primary objective was to compare overall survival for patients in both groups. For secondary objectives, we compared the success of second-line therapy and estimated the costs of imaging for each group. After 5 years of follow-up, the overall survival rate was 97% (95% confidence interval, 92%-99%) in the routine surveillance imaging group and 96% (95% confidence interval, 87%-99%) in the clinical surveillance group (P = .41). There were few relapses in each group, and all patients who relapsed in both groups achieved complete remission with second-line therapy. The charges associated with routine surveillance imaging were significantly higher than those for the clinical surveillance strategy, with no apparent clinical benefit. Clinical surveillance was not inferior to routine surveillance imaging in patients with cHL who achieved complete remission with frontline therapy. Routine

Both bipolar disorder (BD) and childhood trauma are associated with cognitive impairment. People with BD have high rates of childhood trauma, which confer greater overall disease severity, but, it is unknown if childhood trauma is associated with greater neurocognitive impairment in BD patients early in the course of their illnesses. In this study, we investigated the impact of childhood trauma on specific cognitive dysfunction in patients who recently recovered from their first episode of mania. Data were available for 64 patients and 28 healthy subjects matched by age, gender and pre-morbid IQ, recruited from a large university medical center. History of childhood trauma was measured using the Childhood Trauma Questionnaire. Cognitive function was assessed through a comprehensive neuropsychological test battery. Trauma was associated with poorer cognitive performance in patients on cognitive measures of IQ, auditory attention and verbal and working memory, and a different pattern was observed in healthy subjects. We had a modest sample size, particularly in the group of healthy subjects with trauma. Childhood trauma was associated with poorer cognition in BD patients who recently recovered from a first episode of mania compared to healthy subjects. The results require replication, but suggest that the co-occurrence of trauma and bipolar disorder can affect those cognitive areas that are already more susceptible in patients with BD.

Material and methods: We included electronic record data on CXR performed on patients aged 40 to 99 years from nine radiology departments covering 20 Danish hospitals. From each department, we included data from three randomly selected weeks between 2004 and 2011 (reference standard. In two versions of the DNPR from the State Serum Institute (SSI and Statistics Denmark, respectively, we investigated the proportion of registered CXR compared to the reference standard. Furthermore, we compared the completeness of the recorded data according to the responsible department (main department. Results: We identified 11,235 patients and 12,513 CXR in the reference standard. The data from the SSI contained 12,265 (98% CXR, whereas the data from Statistics Denmark comprised 9,151 (73.1% CXR. The completeness of the SSI data was fairly constant across years, radiology departments, medical specialties, and age groups. The data from Statistics Denmark was almost complete in 2011 (95.8%. However, for the remaining study period, the data with radiology departments registered as the main department were lacking in the version from Statistics Denmark, and so the overall completeness was 73.1%. Conclusion: The completeness of CXR registrations varied between 98% and 73% depending on the information source, and this should be considered when investigating radiology services in the basis of DNPR.

Developments in healthcare technology could improve patient care and reduce healthcare costs. There is a need to facilitate communication and increase efficiency in surgical pre-assessment clinics. This study aimed to develop an iPad application to deliver an electronic patient questionnaire, and to evaluate its use in the pre-assessment environment. Software was developed, MyOp, for a standard iPad that mirrored the paper-based pre-assessment system, with features designed for ease of patient use and remote data transfer. A case-control study was conducted, comparing use of MyOp with paper-based practice, to evaluate feasibility and patient preference. Patients were offered the use of MyOp or paper-based system. Outcomes measured included time to complete iPad questionnaire, consultation duration, and a patient preference questionnaire. MyOp cost £3500 to develop. 104 individuals participated in the study, 53 MyOp and 51 controls. MyOp reduced the median consultation duration by 5.00 min. A reduction was seen in all subgroups except those aged over 70 or urology patients. Patients preferred to complete the form independently, using a touchpad or computer but expressed concerns about data security. Use of an electronic patient questionnaire reduces consultation time delivering greater efficiency of pre-assessment nurse time. Preconceived ideas about the use of technology in older age groups are likely inaccurate and less of a barrier than previously thought. Electronic pre-assessments could be used routinely to reduce demands on healthcare facilities, improve patient care, and triage patients prior to clinic attendance.

Inductive matrix completion for predicting gene-disease associations.

Natarajan, Nagarajan; Dhillon, Inderjit S

2014-06-15

Most existing methods for predicting causal disease genes rely on specific type of evidence, and are therefore limited in terms of applicability. More often than not, the type of evidence available for diseases varies-for example, we may know linked genes, keywords associated with the disease obtained by mining text, or co-occurrence of disease symptoms in patients. Similarly, the type of evidence available for genes varies-for example, specific microarray probes convey information only for certain sets of genes. In this article, we apply a novel matrix-completion method called Inductive Matrix Completion to the problem of predicting gene-disease associations; it combines multiple types of evidence (features) for diseases and genes to learn latent factors that explain the observed gene-disease associations. We construct features from different biological sources such as microarray expression data and disease-related textual data. A crucial advantage of the method is that it is inductive; it can be applied to diseases not seen at training time, unlike traditional matrix-completion approaches and network-based inference methods that are transductive. Comparison with state-of-the-art methods on diseases from the Online Mendelian Inheritance in Man (OMIM) database shows that the proposed approach is substantially better-it has close to one-in-four chance of recovering a true association in the top 100 predictions, compared to the recently proposed Catapult method (second best) that has bigdata.ices.utexas.edu/project/gene-disease. © The Author 2014.

Pilot study. Single-nucleotide polymorphisms (SNPs) in TRPA1 gene are related to the etiology of chronic pain. The study is a pilot study with the primary objective of analyzing these SNPs in Spanish patients with chronic and complete spinal cord injury (SCI) and neuropathic pain (NPP). Asepeyo Hospital Department of Chronic and Complete SCI. Twelve patients with chronic and complete SCI and NPP, and 12 patients with chronic and complete SCI with no pain were reviewed. International Spinal Cord Injury Pain Classification (LANSS) and visual analog score (VAS) were chosen to classify pain syndrome. SNPs were identified by melting analysis after DNA amplification with real-time fluorescence PCR. There were differences in rs11988795 variant: GG homozygous ( p  = 0.01) and G allele ( p  = 0.001) were more frequent in SCI patients with no pain. There were differences in rs13255063 variant: TT homozygous were prevalent ( p  = 0.03) in patients with NPP. Until now this is the first study to show a description of TRPA1 SNPs in Spanish patients with chronic and complete SCI and NPP. These results suggest that GG genotype in rs11988795 variant and G allele could be protective factors against NPP. TT genotype in rs13255063 variant could be a risk factor for NPP. Neuropathic pain after spinal cord injuries may have genetic contributions.

Matrix completion by deep matrix factorization.

Fan, Jicong; Cheng, Jieyu

Conventional methods of matrix completion are linear methods that are not effective in handling data of nonlinear structures. Recently a few researchers attempted to incorporate nonlinear techniques into matrix completion but there still exists considerable limitations. In this paper, a novel method called deep matrix factorization (DMF) is proposed for nonlinear matrix completion. Different from conventional matrix completion methods that are based on linear latent variable models, DMF is on the basis of a nonlinear latent variable model. DMF is formulated as a deep-structure neural network, in which the inputs are the low-dimensional unknown latent variables and the outputs are the partially observed variables. In DMF, the inputs and the parameters of the multilayer neural network are simultaneously optimized to minimize the reconstruction errors for the observed entries. Then the missing entries can be readily recovered by propagating the latent variables to the output layer. DMF is compared with state-of-the-art methods of linear and nonlinear matrix completion in the tasks of toy matrix completion, image inpainting and collaborative filtering. The experimental results verify that DMF is able to provide higher matrix completion accuracy than existing methods do and DMF is applicable to large matrices. Copyright © 2017 Elsevier Ltd.

With the advent of the deep economic crisis in Argentina on 2001, the recovery of companies through to the creation of the Cooperatives Working Self-Management or Factories Recovered by its workers was constituted as one of the ways in which the salaried disobeyed the increasing unemployment. When the companies turn into recovered factories they tend to leave of side practices that have been seen like imposed by the previous organization and not understanding them as a primary condition for the execution of his tasks. Safety and ergonomics are two disciplines that are no longer considered relevant to the daily work. Therefore this investigation aims to revalue, undergo semantic to give back to a place in every organization analyzed. This research developed a self-diagnostic tool for working conditions, and the environment, present in the recovered factories.

Full Text Available The aim of the present study was to examine the relationship between emotional intelligence and recovering from negative emotions induction, using a performance test to measure Emotional Inteligence (EI. Sixty seven undergraduates participated in the procedure, which lasted 75 minutes and was divided into three stages. At Time 1, subjects answered the STAI-S, POMS-A, and EI was assessed by MSCEIT. At Time 2, negative emotions were induced by 9 pictures taken from the International Affective Picture System (IAPS and participants were asked to complete a second STAI-S and POMS-B questionnaires. At Time 3 participants were allowed to rest doing a distracting task and participants were asked to complete a third STAI-S and POMS-A questionnaires. Results showed that the branches of the MSCEIT emotional facilitation and emotional understanding are related to previous mood states and mood recovery, but not to mood reactivity. This finding contrasts nicely with studies on which emotional recovery was assessed in relation to EI self-reported measures, highlighting the perception and emotional regulation.

It is unknown if abnormal anal sphincter function as assessed by anorectal manometry is still present years after resolution of chronic constipation and encopresis. Twenty healthy controls, 12 children with constipation but no encopresis, and 20 children with chronic constipation and encopresis underwent anorectal manometric testing, using intraluminal pressure transducers and a balloon for rectal distention. Anorectal measurements were repeated in the 20 constipated and encopretic children 2.5-4 yr after treatment began; 11 children had recovered for at least 1 yr. The mean values of anal resting tone and of anal pull-through pressure were lower in the constipated and encopretic children than in the 20 control children (p less than 0.003). Percent relaxation of the rectosphincteric reflex after rectal distention of 30 and 60 ml was lower in constipated children with and without encopresis than in controls (p less than 0.003), whereas the means of rectosphincteric reflex threshold were comparable in the three groups of children. Three years after initiation of treatment with milk of magnesia, high-fiber diet, and bowel training techniques, the mean values of anal resting tone, anal pull-through pressure, and percent relaxation of rectosphincteric reflex remained significantly lower in both recovered and nonrecovered constipated and encopretic patients compared with controls. It was suggested that the underlying cause of chronic constipation is the decreased ability of the internal anal sphincter to relax with rectal distention, and the hypotonia of the anal canal is responsible for the encopresis. Abnormal anorectal functions were still present years after cessation of treatment and recovery and put the recovered patient at risk for recurrence of chronic constipation and encopresis.

Full Text Available Blindness following a LeFort I osteotomy is a rare but extremely serious complication. Ten cases have been reported to date. None of these patients recovered vision. Optic neuropathy is believed to be the cause but the exact mechanism has not been settled. We report the first, and the only two, documented cases of complete loss of vision that recovered subsequently. The first patient was a 19-year-old male with repaired bilateral cleft lip and palate. He developed loss of vision in the right eye on the second postoperative day. The second patient was a 22-year-old male with repaired unilateral cleft lip and palate. He developed complete loss of vision in the left eye on the day of surgery. Both these patients underwent ongoing studies, which did not show any abnormalities. Both were treated with methylprednisolone. Both the patients gradually showed improvement in their vision. The first patient recovered normal vision several months postoperatively. The second patient′s vision improved to 4/60 by 4 months postoperatively. We discuss the probable mechanisms of optic nerve injury and also the possible reasons why sight was restored in these patients. This is a rare but serious complication following a fairly common procedure. Through this article we wish to create an awareness of this complication and also a possible way of avoiding such a disaster.

Complete Cranial Iliac Osteotomy to Approach the Lumbosacral Foramen

Directory of Open Access Journals (Sweden)

Barbara Dyall

2017-05-01

Full Text Available An approach using a complete cranial iliac osteotomy (CCIO to access the lumbosacral (LS foramen in dogs from lateral was developed using cadavers and applied in a clinical patient with degenerative lumbosacral stenosis (DLSS. The foraminal enlargement in the cadavers and the patient was documented on postoperative CT scans. The preoperative CT scan of the patient showed moderate cranial telescoping of the sacral roof and a moderate central disk protrusion, leading to moderate to severe compression of the cauda equina. In addition, there was lateral spondylosis with consequential stenosis of the right LS foramen. The right L7 nerve had lost its fat attenuation and appeared thickened. After a routine L7S1 dorsal laminectomy with a partial discectomy, a CCIO was performed, providing good access to the LS foramen and the adhesions around the proximal L7 nerve caudoventral to the foramen. The osteotomy was stabilized with a locking plate and a cerclage wire. The dog recovered well from the procedures and after 36 h, the dog walked normally and was discharged from the hospital. Eight and 16 weeks later, the signs of the DLSS had markedly improved. From these data, it can be concluded that the CCIO is a useful approach to the LS foramen and intervertebral disk in selected patients with DLSS, giving good access to the structures around the LS foramen.

Cardiodepressant IgG3 autoantibodies (CD-Abs) can be targeted by apheresis. Using blinded measurements of CD-Abs before and after immunoadsorption (IA), the cardiac function of patients who did or did not achieve complete CD-Abs elimination was compared. Autoantibodies were completely removed from 18 patients with heart failure (New York Heart Association class 3 or 4, left ventricular ejection fraction (LVEF) <30%) using a selective IgG3 adsorption column. All patients had anti-β1-adrenergic and/or M2-muscarinic autoantibodies before IA, and all LVEF were measured on radionuclide ventriculography. CD-Abs were measured before and after IA, and patient status was blinded until all measurements were collected. Treatment was defined as complete when CD-Abs status changed from positive to negative after IA. Other instances were defined as incomplete. Six-min walk test results and brain natriuretic peptide levels improved significantly after IA (P<0.01). The increase in LVEF 3 months after IA was significantly greater after complete treatment in comparison to the incomplete treatment group (19±8-29±9% vs 18±9-17±8%, P<0.01). Cardiac insufficiency events were also more frequent in the incomplete treatment group. Complete elimination of CD-Abs with apheresis may be related to improved cardiac function in the treatment of heart failure. (author)

Full Text Available Background and Aims: Removable complete denture is one of the most common treatment modalities for completely edentulous patients. After denture insertion, patient very often faces problems with the denture even after complete care is taken during fabrication procedure. Most common complaint is traumatic ulcers. The present study aimed to locate the most common areas of ulcerations due to complete dentures, how frequently they occur and how many times patient visits for adjustment after insertion of complete denture. Materials and Methods: Two hundred and twenty-one patients were selected and were delivered complete dentures. Dentures were fabricated for all the patients. Each step of denture fabrication was controlled and guided by a prosthodontist. After placement of dentures, patients were evaluated at every recall visit and their dentures were adjusted. All the details of each visit (area of ulceration and number of visits were recorded in a self-designed format. Descriptive statistical analysis was done using SPSS version 13 software. Chi-squared test was used to evaluate the correlation between mucosal injuries and postinsertion day and the relationship between lesions, patient age, and patient gender. Results: All the 221 patients required denture adjustment due to mucosal injuries. No significant difference was found between denture-related injuries between males and females. Injuries related to mandibular dentures were significantly higher than those related to maxillary dentures. In mandible, the most common area of mucosal injury is posterior one-third of alveololingual sulcus; while in maxilla, the most common area of mucosal injury is labial frenum. Conclusion: Postinsertion adjustments are an important aspect of rehabilitating patient with complete dentures. Most of the denture-related injuries were in limiting areas. Proper border molding techniques, accurate secondary impressions, and use of pressure indicating paste during

Preoperative neoadjuvant therapy (chemotherapy and radiotherapy is the gold standard in the management of rectal cancer before surgical resection. The literature includes reports of absence of neoplastic cells after neoadjuvant therapy. There are no reports on complete pathological response to this type of therapy in Mexico. Objectives: Determine the percentage of patients with rectal adenocarcinoma with complete pathological response after neoadjuvant therapy. All patients were treated in a colorectal surgery department of a tertiary care hospital. Materials and methods: A total of 64 patients with rectal adenocarcinoma diagnosed by biopsy were treated from January 2010 to December 2015. Demographic data, tumour localisation, pathological report, TNM stage, neoadjuvant therapy, surgical procedure and postoperative pathological report were collected from patient records. Results: Mean patient age was 52.8 years (range of 26–73; 31 were women and 33 men. Twenty-seven patients (27 were stage II and 27 stage III. The preoperative biopsy results were classified as: well differentiated (10; moderately differentiated (48; and poorly differentiated/undifferentiated adenocarcinoma (6. Twenty patients received neoadjuvant therapy (31.2%. In these, 2 tumours were localised in the upper third of the rectum, 6 in the middle third, and 12 in the lower third. Six patients underwent abdominoperineal resection, 10 total mesorectal excision, and four posterior pelvic exenteration. Six patients undergoing neoadjuvant therapy had a complete pathological response. Conclusions: The percentage of patients with a complete pathological response is similar to that in other literature reports. More evidence is needed to define good prognosis factors in patients who might not require surgery after neoadjuvant therapy. Resumen

Full Text Available Incomplete Kawasaki disease (iKD is considered to be a less complete form of Kawasaki disease (cKD, and several differences in the laboratory presentations of iKD and cKD have been noted. We investigated serum procalcitonin levels in patients with iKD, cKD, and other febrile diseases (a control group. Seventy-seven patients with cKD, 24 with iKD, and 41 controls admitted to our hospital from November 2009 to November 2011 were enrolled in the present study. We obtained four measurements of serum procalcitonin levels and those of other inflammatory markers from each patient. Samples were taken for analysis on the day of diagnosis (thus before treatment commenced; D0 and 2 (D2, 14 (D14, and 56 days (D56 after intravenous immunoglobulin infusion. We obtained control group data at D0. The mean D0 serum procalcitonin levels of cKD patients (0.71±1.36 ng/mL and controls (0.67±1.06 ng/mL were significantly higher than those of iKD patients (0.26±0.26 ng/mL (P=0.014 and P=0.041, resp.. No significant difference in mean procalcitonin level was evident among groups at any subsequent time. In conclusion, the serum procalcitonin level of patients with acute-stage cKD was significantly higher than that of iKD patients.

Efficient tensor completion for color image and video recovery: Low-rank tensor train

This paper proposes a novel approach to tensor completion, which recovers missing entries of data represented by tensors. The approach is based on the tensor train (TT) rank, which is able to capture hidden information from tensors thanks to its definition from a well-balanced matricization scheme. Accordingly, new optimization formulations for tensor completion are proposed as well as two new algorithms for their solution. The first one called simple low-rank tensor completion via tensor tra...

This study aims to determine therapeutic effect of hemoperfusion on patients with acute toxic encephalopathy induced by silkworm chrysalis ingestion. Three patients who developed toxic encephalopathy after chrysalis ingestion were analysed. Two patients lost their consciousness, while two patients had typical extrapyramidal tremor symptoms. Further neurological examination revealed various degrees of muscle strength impairment in these patients. All of them received treatments of omeprazole (40 mg/day), furosemide (one dose of 20 mg), vitamin C (2.0 g/day), calcium gluconate (2.0 g/day) and rehydration with glucose and sodium chloride (1500 ml/day). In addition, they received hemoperfusion treatment for 1.5 h. All patients recovered well after hemoperfusion. Two patients with loss of consciousness significantly recovered at 45 min and 65 min after hemoperfusion, respectively. All tremor symptoms were completely resolved in these patients at 30 min, 50 min, and 70 min following treatment, respectively. After the hemoperfusion treatment, encephalopathy symptoms of two patients had completely disappeared. All patients were followed up for one month and did not report any abnormalities. Our study indicates that hemoperfusion could be a useful and efficient treatment strategy for patients with acute encephalopathy after silkworm chrysalis ingestion. Larger clinical trials with longer follow-up are warranted to confirm the clinical benefit of hemoperfusion. © The Author(s) 2015.

Background Poor response rates to postal questionnaires can introduce bias and reduce the statistical power of a study. To improve response rates in our trial in primary care we tested the effect of introducing an unconditional direct payment of £5 for the completion of postal questionnaires. Methods We recruited patients in general practice with knee problems from sites across the United Kingdom. An evidence-based strategy was used to follow-up patients at twelve months with postal questionnaires. This included an unconditional direct payment of £5 to patients for the completion and return of questionnaires. The first 105 patients did not receive the £5 incentive, but the subsequent 442 patients did. We used logistic regression to analyse the effect of introducing a monetary incentive to increase the response to postal questionnaires. Results The response rate following reminders for the historical controls was 78.1% (82 of 105) compared with 88.0% (389 of 442) for those patients who received the £5 payment (diff = 9.9%, 95% CI 2.3% to 19.1%). Direct payments significantly increased the odds of response (adjusted odds ratio = 2.2, 95% CI 1.2 to 4.0, P = 0.009) with only 12 of 442 patients declining the payment. The incentive did not save costs to the trial – the extra cost per additional respondent was almost £50. Conclusion The direct payment of £5 significantly increased the completion of postal questionnaires at negligible increase in cost for an adequately powered study. PMID:17326837

Although several studies have been conducted on the role of surgery in localized neuroblastoma, the impact of surgical timing and extent of primary tumor resection on outcome in high-risk patients remains controversial. Patients from the German neuroblastoma trial NB97 with localized neuroblastoma INSS stage 1-3 age > 18 months were included for retrospective analysis. Imaging reports were reviewed by two independent physicians for Image Defined Risk Factors (IDRF). Operation notes and corresponding imaging reports were analyzed for surgical radicality. The extent of tumor resection was classified as complete resection (95-100%), gross total resection (90-95%), incomplete resection (50-90%), and biopsy (Neuroblastoma Risk Group (INRG) staging system. Survival curves were estimated according to the method of Kaplan and Meier and compared by the log-rank test. A total of 179 patients were included in this study. 77 patients underwent more than one primary tumor operation. After best surgery, 68.7% of patients achieved complete resection of the primary tumor, 16.8% gross total resection, 14.0% incomplete surgery, and 0.5% biopsy only. The cumulative complication rate was 20.3% and the surgery associated mortality rate was 1.1%. Image defined risk factors (IDRF) predicted the extent of resection. Patients with complete resection had a better local-progression-free survival (LPFS), event-free survival (EFS) and OS (overall survival) than the other groups. Subgroup analyses showed better EFS, LPFS and OS for patients with complete resection in INRG high-risk patients. Multivariable analyses revealed resection (complete vs. other), and MYCN (non-amplified vs. amplified) as independent prognostic factors for EFS, LPFS and OS. In patients with localized neuroblastoma age 18 months or older, especially in INRG high-risk patients harboring MYCN amplification, extended surgery of the primary tumor site improved local control rate and survival with an acceptable risk of

Employing background-field method and super-heat-kernel expansion, we compute the complete one-loop renormalization of the electroweak chiral Lagrangian with a light Higgs boson. Earlier results from purely scalar fluctuations are confirmed as a special case. We also recover the one-loop renormalization of the conventional Standard Model in the appropriate limit.

Central nervous system depressant drugs (CNS-Ds) are known to impair cognitive functions. Overdose of these drugs is common, and most of the hospital-treated patients are discharged within 24 to 48 hours. No previous studies have examined whether they have residual impairment at the time of discharge. Our aim was to evaluate whether patients with CNS-D overdose are impaired in cognitive domains important in daily activities at that time. We compared visuomotor skills (Trail-Making Test A and Choice Reaction Time), executive functions (viz attentional set-shifting: Trail-Making Test B; and planning: Stockings of Cambridge Task from the Cambridge Neuropsychological Test Automated Battery), working memory (Letter-Number Sequencing), and impulsivity and decision making (Cambridge Neuropsychological Test Automated Battery Information Sampling) in 107 patients with CNS-D overdose (benzodiazepines, opioids, or antipsychotics) with a control group of 68 with non-CNS-D overdose (acetaminophen, selective serotonin reuptake inhibitors, and serotonin noradrenaline reuptake inhibitors) on discharge from hospital. Outcome measures were adjusted for demographic and clinical covariates in multivariate regression models. Compared with the controls, patients in the CNS-D group were significantly impaired in all domains: they had prolonged Trail-Making completion times and reaction times, poorer working memory and planning and were more impulsive in decision making. Their Stockings of Cambridge Task performance was comparable to that of the control group for simple problems but worsened with increasing task complexity. The results show that patients with CNS-D overdose could be impaired in multiple cognitive domains underlying everyday functioning even at the time they are deemed medically fit to be discharged. Such impairments could adversely affect social and professional lives of this relatively young population during the immediate postdischarge period.

Prosthetic rehabilitation of a completely edentulous patient should never be restricted to the replacement of missing teeth. The ultimate aim of complete denture treatment should be restoration of the full range of oral functions and esthetics. Slumped cheeks are always a concern for esthetically demanding complete denture patients. This article describes a simple, scientific, cost-effective technique to improve facial esthetics in a completely edentulous patient with the help of a cheek plumper. The technique used here implements the concept of neutral zone to precisely determine the amount of space available for the cheek plumper. The simple friction lock attachments that retained the cheek plumpers on the prosthesis were also fabricated after determining the space available in the appropriate areas. Thus an effort was made to keep the cheek plumpers unobtrusive yet effective to ensure complete integration of the prosthesis into the stomatognathic system. © 2017 by the American College of Prosthodontists.

Hypoplasia of the lateral femoral condyle has been reported in discoid lateral meniscus patients, but associated imaging findings in the axial plane have not been characterized. In this study, we aimed to identify differences in the lateral femoral condyle between patients with discoid lateral meniscus and those with normal menisci using axial MRI images. Twenty-three patients (24 knees) with complete discoid lateral meniscus, 43 (45 knees) with incomplete discoid lateral meniscus, and 50 with normal menisci (50 knees) were enrolled and distributed into three groups. Two new angles, posterior lateral condylar angle (PLCA) and posterior medial condylar angle (PMCA), were measured on axial MRI images; the posterior condylar angle (PCA) was also measured. Differences between the three groups in the PLCA, PMCA, PCA, and PLCA/PMCA were analysed. The predictive value of PLCA and PLCA/PMCA for complete discoid lateral meniscus was assessed. In the complete discoid lateral meniscus group, PLCA and PLCA/PMCA were significantly smaller compared with the normal meniscus group and the incomplete discoid lateral meniscus group (P meniscus group compared with the incomplete discoid lateral meniscus group (P meniscus group (P meniscus. Hypoplasia of the posterior lateral femoral condyle is typically seen in patients with complete discoid lateral meniscus. PLCA and PLCA/PMCA can be measured from axial MRI images and used as excellent predictive parameters for complete discoid lateral meniscus. Diagnostic study, Level III.

Low-dose tryptophan depletion in recovered depressed women induces impairments in autobiographical memory specificity.

Depressed patients perform poorly on tests of autobiographical memory specificity (AMS); this may have negative consequences for other important cognitive abilities, delays recovery from mood episodes, and, in recovered patients, may mediate vulnerability to future episodes. Although the cognitive mechanisms underlying AMS deficits are beginning to be understood, the neurobiological mechanisms remain unclear. Serotonin is implicated in both depression and long-term memory; therefore, temporary lowering of brain serotonin function via acute tryptophan depletion (ATD) offers a means of studying the role of serotonin in autobiographical memory specificity. In this study, 24 previously depressed women underwent low-dose ATD or sham depletion and completed tests of initial and delayed memory, recollection- and familiarity-based recognition, and AMS. ATD did not differentially affect state mood. Compared with sham depletion, ATD impaired immediate recall on the Auditory Verbal Learning Test. Although ATD did not differentially impair recollection- and familiarity-based recognition, it did slow recognition of positive words. ATD also reduced autobiographical memory specificity in response to negative cue words. The results confirm previous findings that low-dose ATD can reinstate depression-congruent biases in cognition without causing depressive mood in vulnerable populations. The ATD-induced reduction in memory specificity suggests that serotonergic dysfunction may mediate depressive deficits in autobiographical memory; the interaction of cognitive and neurobiological vulnerability mechanisms is discussed.

To investigate the feasibility of a 13-week mentoring programme in providing social support to promote hope for recovery in anorexia nervosa. With no clear first-line psychological treatment for people with anorexia nervosa, mentoring support programmes, as an adjunct to treatment, may provide the social support necessary to promote hope for recovery. A mixed-method study; participatory action research. Women (n = 11), recovering and who had recovered from anorexia nervosa, participated in the programme and completed self-report questionnaires related to quality of life, distress and the mentoring relationship at different time points. Qualitative feedback from logbooks, workshop evaluation questionnaires, interviews and focus groups was also collected to assess the programme's acceptability. General compliance for completing most study outcome questionnaires was 90%; however, the mentoring relationship questionnaires were not completed to the same degree. Five key themes emerged from the focus group/interview data: (i) she understands me and could relate to me; (ii) reconnecting with the world-asking questions and being challenged; (iii) mentors' altruistic motivations and the transformation and discovery of self; (iv) instilling hope-recovery is possible; and (v) effective communication-the key to successful mentoring. Further research is needed; however, the results provide preliminary support for the mentoring programme's feasibility as an adjunct to treatment. We found that having someone who understands, to talk and share with, met a clear need for people with anorexia nervosa. While further research is warranted mentoring support or recovered mentors, may play a potentially valuable role in supporting those in community settings. © 2017 John Wiley & Sons Ltd.

Transuranium element recovering method for spent nuclear fuel

Spent fuels are dissolved in nitric acid, the obtained dissolution liquid is oxidized by electrolysis, and nitric acid of transuranium elements are precipitated together with nitric acid of uranium elements from the dissolution solution and recovered. Namely, the transuranium elements are oxidized to an atomic value level at which nitric acid can be precipitated by an oxidizing catalyst, and cooled to precipitate nitric acid of transuranium elements together with nitric acid of transuranium elements, accordingly, it is not necessary to use a solvent which has been used so far upon recovering transuranium elements. Since no solvent waste is generated, a recovery method taking the circumstance into consideration can be provided. Further, nitric acid of uranium elements and nitric acid of transuranium elements precipitated and recovered together are dissolved in nitric acid again, cooled and only uranium elements are precipitated selectively, and recovered by filtration. The amount of wastes can be reduced to thereby enabling to mitigate control for processing. (N.H.)

Full Text Available BACKGROUND: Polyneuropathy, organomegaly, endocrinopathy, monoclonal syndrome (POEMS is a rare paraneoplastic syndrome associated with plasma cell dyscrasia. CASE REPORT: A 48-year-old man presented with a 1-year history of paresthesia and progressive weakness of extremities. Diagnosis of POEMS syndrome was made for him on the basis of clinical presentation, additional physical findings, typical sclerotic bone lesion, and bone marrow findings. In last admission, he explained episodes of dyspnea and chest pain that associated with frequent premature ventricular contraction in his electrocardiograph. Patient heart monitoring showed some episodes of complete heart block. Infra-His atrioventricular block in electro-physiologic study was detected. He had no history of ischemic heart disease. His cardiopulmonary findings on examination were normal. All results of cardiac biomarkers and serum electrolytes and repeated echocardiography were within normal range. Cong red staining of rectal fat pad biopsy was negative. After pacemaker insertion radiation of sclerotic bone, lesion started for him, but radiotherapy was ineffective, and he expired with respiratory failure. Complete heart block in POEMS syndrome has not been reported previously, and it is the first POEMS case with complete heart block. CONCLUSION: Complete heart block is a cardiac manifestation of POEMS syndrome.   Keywords: Complete Heart Block, POEM Syndrome, Multiple Meloma

Liquor obtained by scrubbing coal gas with sea-water or fresh water, and containing or having added to it finely-divided carbonaceous material in suspension, is subjected to a froth-flotation process to recover the carbonaceous matter and organic materials in the froth, and render the remaining liquor innocuous. Liquor obtained by scrubbing distillation gases, such as coal gas, may be used as a frothing-agent in a froth flotation process for the recovery of carbonaceous substances such as coal from materials containing them, thereby producing a froth containing the coal, etc., and also the organic materials from the liquor. In some cases the effluent may be diluted with sea-water, and, in recovering carbonaceous shales, there may be added to the liquor a small proportion of paraffin oil.

Critical limb ischemia (CLI) patients with tissue loss have been recognized to have a poor survival rate. In this study, we aimed to determine whether the prognosis of CLI patients with tissue loss improves after complete wound healing is achieved by endovascular therapy. We treated 187 CLI patients with tissue loss by endovascular therapy from April 2007 to December 2012. Among these patients, 113 patients who achieved complete wound healing were enrolled. The primary end point was survival rate at 3 years. The secondary end points were limb salvage rate and recurrence rate of CLI at 3 years. The mean follow-up period after achievement of complete wound healing was 32 ± 18 months. At 1 year, 2 years, and 3 years, the survival rates were 86%, 79%, and 74%; the limb salvage rates were 100%, 100%, and 100%; the recurrence rates of CLI were 2%, 6%, and 9%, respectively. On multivariate Cox proportional hazard analysis, age >75 years (hazard ratio, 3.18; 95% confidence interval, 1.23-8.24; P = .017) and nonambulatory status (hazard ratio, 2.46; 95% confidence interval, 1.08-5.65; P = .035) were identified as independent predictors of death for CLI patients with tissue loss even after complete wound healing was achieved. The Kaplan-Meier curve for the overall survival rate at 3 years showed that CLI patients of older age (>75 years) had a significantly decreased survival rate compared with CLI patients of younger age (≤75 years) (58% vs 87%; log-rank test, P wound healing was achieved. Nonambulatory status and age >75 years can serve as predictors of death even after complete wound healing is achieved. Copyright © 2015 Society for Vascular Surgery. Published by Elsevier Inc.

Characterisation of solid recovered fuels for direct co-firing in large-scale PF power plants

Energy Technology Data Exchange (ETDEWEB)

Dunnu, Gregory

2013-04-01

Solid Recovered Fuels are solid fuels prepared from high calorific fractions of non-hazardous waste materials intended to be co-fired in coal power plants and industrial furnaces (CEN/TC 343). They are composed of a variety of materials of which some, although recyclable in theory, may be in a form that makes their recycling an unsound option. The SRF with a typical size range of 3 mm through 25 mm are to be directly co-fired in an existing pulverised coal power plant. In comparison to pulverised coal, the particle size distribution of the SRF is of several magnitudes higher, resulting in a different burnout behaviour. Size reduction of the SRF to a fraction similar to coal is not economically feasible. The aim here is, therefore, the direct co-firing of the solid recovered fuels in the boilers without any further size reduction. This approach, however, bears the risk of incomplete combustion if the injection points of the solid recovered fuels are not optimally selected. Accordingly, the prediction of the burner levels, at which the solid recovered fuels should be injected and whether or not a complete combustion will be achieved under full load condition, is the primary objective of this dissertation. In this research work, laboratory experiments have been conducted to forecast the success of co-firing the SRF in a commercial pulverised coal power plant. It involves the analyses of the fuel and its intermediate chars generated at conditions comparable to boiler conditions to determine some characteristic parameters, namely the burnout time, the aerodynamic lift velocity, the drag coefficient and the apparent densities. The data gathered from the laboratory experiments are transferred to boiler conditions to determine the particle trajectories and the maximum distance likely to travel before they are completely converted in the boiler. Different scenarios are examined and based on the results the best boiler injection points are predicted. Furthermore, an on

We report the uncommon clinical course of tetanus in a completely immunized 14-year-old boy. His initial symptoms, which included a flaccid paralysis, supported a diagnosis of botulism. Preliminary mouse-test results with combined botulinum antitoxins A, B, and E, obtained from tetanus-immunized horses, backed this diagnosis. The change in his clinical course from paralysis to rigor and the negative, more specific, botulinum mouse test with isolated botulinum antitoxins A, B, and E, obtained from nonvaccinated rabbits, disproved the diagnosis of botulism. Tetanus was suspected despite complete vaccination. The final results of a positive mouse test performed with isolated tetanus antitoxin confirmed the diagnosis. Adequate treatment was begun, and the boy recovered completely.

High-resolution phase-contrast X-ray computed tomography (CT) reveals the phoretic deutonymph of a fossil astigmatid mite (Acariformes: Astigmata) attached to a spider's carapace (Araneae: Dysderidae) in Eocene (44-49 Myr ago) Baltic amber. Details of appendages and a sucker plate were resolved, and the resulting three-dimensional model demonstrates the potential of tomography to recover morphological characters of systematic significance from even the tiniest amber inclusions without the need for a synchrotron. Astigmatids have an extremely sparse palaeontological record. We confirm one of the few convincing fossils, potentially the oldest record of Histiostomatidae. At 176 µm long, we believe this to be the smallest arthropod in amber to be CT-scanned as a complete body fossil, extending the boundaries for what can be recovered using this technique. We also demonstrate a minimum age for the evolution of phoretic behaviour among their deutonymphs, an ecological trait used by extant species to disperse into favourable environments. The occurrence of the fossil on a spider is noteworthy, as modern histiostomatids tend to favour other arthropods as carriers.

High-resolution phase-contrast X-ray computed tomography (CT) reveals the phoretic deutonymph of a fossil astigmatid mite (Acariformes: Astigmata) attached to a spider's carapace (Araneae: Dysderidae) in Eocene (44–49 Myr ago) Baltic amber. Details of appendages and a sucker plate were resolved, and the resulting three-dimensional model demonstrates the potential of tomography to recover morphological characters of systematic significance from even the tiniest amber inclusions without the need for a synchrotron. Astigmatids have an extremely sparse palaeontological record. We confirm one of the few convincing fossils, potentially the oldest record of Histiostomatidae. At 176 µm long, we believe this to be the smallest arthropod in amber to be CT-scanned as a complete body fossil, extending the boundaries for what can be recovered using this technique. We also demonstrate a minimum age for the evolution of phoretic behaviour among their deutonymphs, an ecological trait used by extant species to disperse into favourable environments. The occurrence of the fossil on a spider is noteworthy, as modern histiostomatids tend to favour other arthropods as carriers. PMID:22072283

To investigate the completeness of pedigree and of number of pedigree analysis to know the acceptable familial history in Korean women with ovarian cancer. Interview was conducted in 50 ovarian cancer patients for obtaining familial history three times over the 6 weeks. The completeness of pedigree is estimated in terms of familial history of disease (cancer), health status (health living, disease and death), and onset age of disease and death. The completion of pedigree was 79.3, 85.1, and 85.6% at the 1st, 2nd, and 3rd time of interview and the time for pedigree analysis was 34.3, 10.8, and 3.1 minutes, respectively. The factors limiting pedigree analysis were as follows: out of contact with their relatives (38%), no living ancestors who know the family history (34%), dispersed family member because of the Korean War (16%), unknown cause of death (12%), reluctance to ask medical history of relatives (10%), and concealing their ovarian cancer (10%). The percentage of cancers revealed in 1st (2%) and 2nd degree (8%) relatives were increasing through surveys, especially colorectal cancer related with Lynch syndrome (4%). Analysis of pedigree at least two times is acceptable in Korean woman with ovarian cancer from the first study. The completion of pedigree is increasing, while time to take family history is decreasing during three time survey.

Full Text Available Background: Gastric cancer (RZ is the second leading cause of cancer in the world leading to death. Although each year the incidence of RZ is lower, it is still one of the highest in the group of most common malignancies. Due to the fact that cancer patients have similar symptoms to other gastrointestinal diseases, it is often detected at an advanced stage. This cancer can be located in different parts of the stomach and often has an unusual course. Surgical treatment of patients with RZ is most often associated with complete gastric excision and causes numerous ailments. Correct preparation of patients for surgery has a significant impact on therapeutic success. A nurse who carries a cancer patient is not only concerned with assessing his / her current state of health, executing medical orders, education on post-hospital leave, but also providing emotional support before surgery. [1,2,3,16]. Aim of the study: Evaluation of patient treatment before complete removal of the stomach from cancer. Material and method: The study was conducted in the period from 17.09.2012 to 15.05.2013 in the group of 60 patients (35 men and 25 women of the II Department and Clinic of General Surgery, Gastroenterology and Gastrointestinal Cancer of the Independent Public Clinical Hospital No. 1 in Lublin. Patients have been qualified for total abdominal surgery for cancer. The research tool was the author's questionnaire survey. The results of the study were statistically analyzed. Results: According to data obtained, more than half (60% of patients presenting with gastric resection at the Clinic of General Surgery, Gastroenterology and Gastrointestinal Diseases of the Independent Public Clinical Hospital No. 1 in Lublin have a high level of care in this department. There was no case for the patient to underestimate nursing care. Conclusions: The majority of patients rated nursing care performed prior to surgery at a high level.

One hundred isolates of the commercial Saccharomyces cerevisiae strain Zymaflore VL1 were recovered from spontaneous fermentations carried out with grapes collected from vineyards located close to wineries in the Vinho Verde wine region of Portugal. Isolates were differentiated based on their mitochondrial DNA restriction patterns and the evaluation of genetic polymorphisms was carried out by microsatellite analysis, interdelta sequence typing and pulsed-field gel electrophoresis (PFGE). Genetic patterns were compared to those obtained for 30 isolates of the original commercialized Zymaflore VL1 strain. Among the 100 recovered isolates we found a high percentage of chromosomal size variations, most evident for the smaller chromosomes III and VI. Complete loss of heterozygosity was observed for two isolates that had also lost chromosomal heteromorphism; their growth and fermentative capacity in a synthetic must medium was also affected. A considerably higher number of variant patterns for interdelta sequence amplifications was obtained for grape-derived strains compared to the original VL1 isolates. Our data show that the long-term presence of strain VL1 in natural grapevine environments induced genetic changes that can be detected using different fingerprinting methods. The observed genetic changes may reflect adaptive mechanisms to changed environmental conditions that yeast cells encounter during their existence in nature. (c) 2007 John Wiley & Sons, Ltd.

Umbilical KeyPort bilateral laparoscopic orchiectomy in patient with complete androgen insensitivity syndrome

Full Text Available MAIN FINDINGS: A 22-year-old woman with complete androgen insensitivity syndrome (CAIS presenting with primary amenorrhea and normal female external genitalia was referred for laparoscopic gonadectomy. She had been diagnosed several years earlier but was reluctant to undergo surgery. CASE HYPOTHESIS: Diagnosis of this X-linked recessive inherited syndrome characterizes by disturbance of virilization in males with an AR mutation, XY karyotipe, female genitalia and severely undescended testis with risk of malignization. The optimal time to orchidectomy is not settled; neither the real risk of malignancy in these patients. Early surgery impacts development of a complete female phenotype, with enlargement of the breasts. Based on modern diagnostic imaging using DCE-MRI and surgical technology with single port laparoscopic access we hypothesize that the optimum time for gonadectomy is not at the time of diagnosis, but once feminization has completed. PROMISING FUTURE IMPLICATIONS: An umbilical laparoendoscopic single-site access for bilateral gonadectomy appears to be the first choice approach as leaves no visible incision and diminishes the psychological impact of surgery in a patient with CAIS absolutely reassured as female. KeyPort, a single port access with duo-rotate instruments developed by Richard Wolf facilitates this surgery and allows excellent cosmetic results.

Breast cancer patients whose tumors achieve a pathological complete response (pCR) with neoadjuvant chemotherapy have a prognosis which is better than that predicted for the stage of their disease. However, within this subgroup of patients, recurrences have been observed. We sought to examine factors associated with recurrence in a population of breast cancer patients who achieved a pCR with neoadjuvant chemotherapy. A retrospective chart review was conducted of all patients with unilateral breast cancer treated with neoadjuvant chemotherapy from January 1, 2000 to December 31, 2010 at one comprehensive cancer center. A pCR was defined as no residual invasive cancer in the breast in the surgical specimen following neoadjuvant therapy. Recurrence was defined as visceral or bony reappearance of cancer after completion of all therapy. Of 818 patients who completed neoadjuvant chemotherapy, 144 (17.6 %) had pCR; six with bilateral breast cancer were excluded from further analysis. The mean time to follow-up was 47.2 months. Among the 138 patients with unilateral breast cancer, there were 14 recurrences (10.1 %). Using a binary multiple logistic regression model, examining types of chemotherapy and surgery, race, lymph node assessment, and lymph node status, breast cancer side, triple-negative status, and radiation receipt, only African-American patients (OR: 5.827, 95 % CI: 1.280-26.525; p = 0.023) were more likely to develop distant recurrence. The mean time to recurrence was 31.9 months. In our study, race was the only independent predictor of recurrence after achieving pCR with neoadjuvant chemotherapy. The reasons for this observation require further study.

The treatment of pain continues to gain in saliency as a component of defining best practice in medical care. Music therapy is an integrative treatment modality that impacts patient outcomes in the treatment of spinal pain. At Mount Sinai Beth Israel, we conducted a mixed-methods study addressing the effects of music therapy interventions on the recovery of patients after spine surgery. The study combined standard medical approaches and integrative music therapy. Sixty patients (35 female, 25 male) ranging in age from 40 to 55 years underwent anterior, posterior, or anterior-posterior spinal fusion and were randomly assigned to either music therapy plus standard care (medical and nursing care with scheduled pharmacologic pain intervention) or standard care only. Measurements for both groups were completed before and after the intervention. Music therapy involved the use of patient-preferred live music that supported tension release/relaxation through incentive-based clinical improvisation, singing, and/or rhythmic drumming or through active visualization supported by live music that encompasses tension resolution. The control and music groups showed significant differences in degree and direction of change in the visual analog scale (VAS) pain ratings from before to after intervention (P = .01). VAS pain levels increased slightly in the control group (to 5.87 from 5.20) but decreased by more than 1 point in the music group (to 5.09 from 6.20). The control and music therapy groups did not differ in the rate of change in scores on Hospital Anxiety and Depression Scale (HADS) Anxiety (P = .62), HADS Depression (P = .85), or Tampa Scale for Kinesiophobia (P = .93). Both groups had slight increases in HADS Anxiety, comparable decreases in HADS Depression, and minimal changes in fear-related movement (Tampa scale).

The role of natural killer (NK; CD3-CD56+)/NKT (CD3+CD56+)-like cells in chikungunya virus (CHIKV) disease progression/recovery remains unclear. Here, we investigated the expression profiles and function of NK and NKT-like cells from 35 chronic chikungunya patients, 30 recovered individuals, and 69 controls. Percentage of NKT-like cells was low in chronic chikungunya patients. NKp30+, CD244+, DNAM-1+, and NKG2D+ NK cell percentages were also lower (MFI and/or percentage), while those of CD94+ and NKG2A+ NKT-like cells were higher (MFI and/or percentage) in chronic patients than in recovered subjects. IFN-γ and TNF-α expression on NKT-like cells was high in the chronic patients, while only IFN-γ expression on NK cells was high in the recovered individuals. Furthermore, percentage of perforin+NK cells was low in the chronic patients. Lower cytotoxic activity was observed in the chronic patients than in the controls. CD107a expression on NK and NKT-like cells post anti-CD94/anti-NKG2A blocking was comparable among the patients and controls. Upregulated inhibitory and downregulated activating NK receptor expressions on NK/NKT-like cells, lower perforin+ and CD107a+NK cells are likely responsible for inhibiting the NK and NKT-like cell function in the chronic stage of chikungunya. Therefore, deregulation of NKR expression might underlie CHIKV-induced chronicity.

Background: Temporary pace maker (tpm) implantation is an emergency procedure, performed in symptomatic patients with AV block We report our experience of temporary pacing at a tertiary care center. It is the first study of its type from a local center. Objectives: To study the clinical course of patients after tpm implantation and to determine indicators of a poor outcome after tpm implantation. Methods: This was descriptive retrospective study. Data of all tpm procedures performed at Children Hospital from 2006 to 2012 was retrieved. We excluded patients with surgically placed tpm leads. All patients receiving transvenous tpm were included in our study. Results: Total of 12 patients received tpm, 8 were male (66.6%) and 4 were female (33.3%). Median age was 6 years ( range 1.4 -13 year ). Mean weight was 30kg, (range 8.7 - 50kg). All of them presented with complete heart block.One patient each had post diphtheria cardiomyopathy, unknown poisoning. The rest had congenital heart block. The mean period between tpm to ppm implantation was 5 days, (range 1 - 30 days). One patient spontaneously reverted to sinus rhythm(8.3%), 6 had ppm implantation (58.3%), 5 patients expired (33.3%). A low Ejection Fraction was found to be associated with a poor outcome (p<0.01). Variables that were associated with a poor outcome(mortality), were SOB (p<0.015), weak pulses (p<0.015), and hepatomegaly (p<0.01). Conclusion: Low Ejection Fraction and Heart failure is associated with a poor outcome and increased mortality in patients with complete AV block. We suggest that pacing should be considered in patients earlier, before they develop signs or symptoms of cardiac dysfunction. (author)

We have obtained previous evidence of limbic dysfunction in middle-aged, asymptomatic offspring of late-onset Alzheimer's disease (LOAD) patients, and failure to recover from proactive semantic interference has been shown to be a sensitive cognitive test in other groups at risk for LOAD. To assess the effects of specific proactive semantic interference deficits as they relate to functional magnetic resonance imaging (fMRI) neocortical and limbic functional connectivity in middle aged offspring of individuals with LOAD (O-LOAD) and age-equivalent controls. We examined 21 O-LOAD and 20 controls without family history of neurodegenerative disorders (CS) on traditional measures of cognitive functioning and the LASSI-L, a novel semantic interference test uniquely sensitive to the failure to recover from proactive interference (frPSI). Cognitive tests then were correlated to fMRI connectivity of seeds located in entorhinal cortex and anterodorsal thalamic nuclei among O-LOAD and CS participants. Relative to CS, O-LOAD participants evidenced lower connectivity between entorhinal cortex and orbitofrontal, anterior cingulate, and anterior temporal cortex. In the offspring of LOAD patients, LASSI-L measures of frPSI were inversely associated with connectivity between anterodorsal thalamus and contralateral posterior cingulate. Intrusions on the task related to frPSI were inversely correlated with a widespread connectivity network involving hippocampal, insular, posterior cingulate, and dorsolateral prefrontal cortices, along with precunei and anterior thalamus in this group. Different patterns of connectivity associated with frPSI were observed among controls. The present results suggest that both semantic interference deficits and connectivity abnormalities might reflect limbic circuit dysfunction as a very early clinical signature of LOAD pathology, as previously demonstrated for other limbic phenotypes, such as sleep and circadian alterations.

Full Text Available Abstract Background Individuals with substance use disorders (SUDs are at increased risk for hepatitis C viral infection (HCV, and few studies have explored their treatment responses empirically. The objective of this study was to assess interferon alpha therapy (IFN completion and response rates among patients with HCV who had a history of comorbid SUDs. More data is needed to inform treatment strategies and guidelines for these patients. Using a medical record database, information was retrospectively collected on 307,437 veterans seen in the Veterans Integrated Service Network 20 (VISN 20 of the Veterans Healthcare Administration (VHA between 1998 and 2003. For patients treated with any type of IFN (including regular or pegylated IFN or combination therapy (IFN and ribavirin who had a known HCV genotype, IFN completion and response rates were compared among patients with a history of SUD (SUD+ Group and patients without a history of SUD (SUD- Group. Results Odds ratio analyses revealed that compared with the SUD- Group, the SUD+ Group was equally likely to complete IFN therapy if they had genotypes 2 and 3 (73.1% vs. 68.0%, and if they had genotypes 1 and 4 (39.5% vs. 39.9%. Within the sample of all patients who began IFN therapy, the SUD- and SUD+ groups were similarly likely to achieve an end of treatment response (genotypes 2 and 3, 52.8% vs. 54.3%; genotypes 1 and 4, 24.5% vs. 24.8% and a sustained viral response (genotypes 2 and 3, 42.6% vs. 41.1%; genotypes 1 and 4: 16.0% vs. 22.3%. Conclusion Individuals with and without a history of SUD responded to antiviral therapy for HCV at similar rates. Collectively, these findings suggest that patients who have co-morbid SUD and HCV diagnoses can successfully complete a course of antiviral therapy.

Full Text Available Abstract Background Healthy lifestyles are an important facet of cardiovascular risk management. Unfortunately many individuals fail to engage with lifestyle change programmes. There are many factors that patients report as influencing their decisions about initiating lifestyle change. This is challenging for health care professionals who may lack the skills and time to address a broad range of barriers to lifestyle behaviour. Guidance on which factors to focus on during lifestyle consultations may assist healthcare professionals to hone their skills and knowledge leading to more productive patient interactions with ultimately better uptake of lifestyle behaviour change support. The aim of our study was to clarify which influences reported by patients predict uptake and completion of formal lifestyle change programmes. Methods A systematic narrative review of quantitative observational studies reporting factors (influences associated with uptake and completion of lifestyle behaviour change programmes. Quantitative observational studies involving patients at high risk of cardiovascular events were identified through electronic searching and screened against pre-defined selection criteria. Factors were extracted and organised into an existing qualitative framework. Results 374 factors were extracted from 32 studies. Factors most consistently associated with uptake of lifestyle change related to support from family and friends, transport and other costs, and beliefs about the causes of illness and lifestyle change. Depression and anxiety also appear to influence uptake as well as completion. Many factors show inconsistent patterns with respect to uptake and completion of lifestyle change programmes. Conclusion There are a small number of factors that consistently appear to influence uptake and completion of cardiovascular lifestyle behaviour change. These factors could be considered during patient consultations to promote a tailored approach to

Full Text Available Denture stomatotos os a common problem of the denture wears, and its etiology is not clear from the literatures. Some studies show that the aetiology is candida albicans, while other reports point out the other agents including candida albicans. The present study was designed to evaluate the prevalence of oral candidiasis in patients using complete denture with different datas. 50 subjects all wearing complete denture participated in this study. The palatal mucosa was swabbed and swabs were cultured in Sabourauds medium containing 0.005% chloramphenicol then cultures were tested with common mycological lab tests. In 80% of patients oral candidiasis have been diagnosed. In the investigation a direct relation between the oral candidiasis and removal of denture at night, denture cleanliness, presence of any suction and symptoms of denture stomatitis was shown. No relation between the oral candidiasis and sex, smoking habit, succeptible disease, angular cheilitis; the recent condition of denture and the retention of denture were found. The findings of our investigation indicates that candida albicans is the causative agent of denture stomatitis while other factors such as denture cleanliness, removal of denture at night and presence of any suction may be considered as well.

Highlights: • MnO 2 is recovered from spent zinc–carbon batteries as nanoflowers structure. • Recovered MnO 2 nanoflowers show high specific capacitance. • Recovered MnO 2 nanoflowers show stable electrochemical cycling up to 900 cycles. • Recovered MnO 2 nanoflowers show low resistance in EIS data. - Abstract: The electrochemical performance of MnO 2 nanoflowers recovered from spent household zinc–carbon battery is studied by cyclic voltammetry, galvanostatic charge/discharge cycling and electrochemical impedance spectroscopy. MnO 2 nanoflowers are recovered from spent zinc–carbon battery by combination of solution leaching and electrowinning techniques. In an effort to utilize recovered MnO 2 nanoflowers as energy storage supercapacitor, it is crucial to understand their structure and electrochemical performance. X-ray diffraction analysis confirms the recovery of MnO 2 in birnessite phase, while electron microscopy analysis shows the MnO 2 is recovered as 3D nanostructure with nanoflower morphology. The recovered MnO 2 nanoflowers exhibit high specific capacitance (294 F g −1 at 10 mV s −1 ; 208.5 F g −1 at 0.1 A g −1 ) in 1 M Na 2 SO 4 electrolyte, with stable electrochemical cycling. Electrochemical data analysis reveal the great potential of MnO 2 nanoflowers recovered from spent zinc–carbon battery in the development of high performance energy storage supercapacitor system

2014-01-01

Full Text Available Introduction. Neoadjuvant chemoradiotherapy and total mesorectal excision are considered the standard treatment for locally advanced rectal cancer. Various studies have reported pathological downstaging and a complete pathological response rate of 15%–27% following neoadjuvant chemoradiotherapy which has translated into improved survival. We endeavour to determine the clinical outcome of patients attaining a complete pathological tumor response following neoadjuvant chemoradiotherapy in the Indian setting where most of our patient population is younger and presents with aggressive tumor biology. Materials and Methods. Clinicopathological and treatment details were recorded for 64 patients achieving pathological complete response from 2010 to 2013. Disease-free survival (DFS, overall survival (OS, and locoregional and systemic recurrence rates were evaluated for these patients. Results. After a median follow-up of 30.5 months (range 11–59 months, the 3-year overall survival (OS was 94.6% and the 3-year disease-free survival (DFS was 88.5%. The locoregional and systemic recurrence rates were 4.7% and 3.1%, respectively. Conclusion. In the Indian subcontinent, despite younger patients with aggressive tumor biology, outcome in complete responders is good.

Prospective cohort with age- and gender-matched controls. To compare psychiatric morbidity between two groups: patients having chronic symptoms after a whiplash injury and patients who recovered completely. Psychiatric morbidity may influence the outcome of somatic diseases, and it has been suggested that psychological factors are often involved in the development of chronic symptoms after whiplash injuries, but there is no study assessing psychiatric morbidity in whiplash-associated disorder (WAD) using the Structured Clinical Interview for DSM-IV. We studied a consecutive sample of 278 patients with a whiplash injury. Eighty-five had persisting neck pain after 1 year, and 38 of these participated in this study. For each patient with chronic neck pain at the 1 year follow-up, a gender- and age-matched recovered patient was selected from the study cohort of 278 cases. Psychiatric morbidity was determined using the Structured Clinical Interview for DSM-IV (SCID). The interview was conducted at 1 year after the accident (360 days, SD 2 days). The chronic WAD group had a significantly (P factor for chronic symptoms after a whiplash injury. The development of chronic symptoms after awhiplash injury seems to be associated with psychiatric vulnerability.

Ryu, Taeha; Kim, Dong Hyuck; Byun, Sung Hye

2018-01-01

Abstract Rationale: In patients with oropharyngeal and nasopharyngeal bleeding, blood aspiration can make airway management difficult and lead to severe pulmonary complications. Patient concerns: A 44-year-old male patient with recurrent epistaxis underwent surgery for hemostasis. The patient aspirated blood through the endotracheal tube when he hiccupped during the surgery. Diagnosis: The patient was diagnosed with blood aspiration after intraoperative fiberoptic bronchoscopy revealed a blood clot and viscous mucus in the airways, but no sign of active bleeding. Interventions: Tracheobronchial suctioning and irrigation with normal saline was performed through the bronchoscope to remove the aspirated blood clot. Prior to emergence from anesthesia, sugammadex was administered to induce complete neuromuscular recovery and enable the patient to cough up any blood remaining in the airways. Outcomes: The patient was successfully extubated and fully recovered with no complications. Lessons: Blood aspiration due to oropharyngeal or nasopharyngeal bleeding can be diagnosed and treated by tracheobronchial suctioning via fiberoptic bronchoscopy. In addition, sugammadex can enable patients to recover spontaneous breathing, facilitate extubation, and enable patients to cough up any blood remaining in the airways. PMID:29642212

A molecular study on the prevalence and virulence potential of Aeromonas spp. recovered from patients suffering from diarrhea in Israel.

Directory of Open Access Journals (Sweden)

Full Text Available BACKGROUND: Species of the genus Aeromonas are native inhabitants of aquatic environments and have recently been considered emerging human pathogens. Although the gastrointestinal tract is by far the most common anatomic site from which aeromonads are recovered, their role as etiologic agents of bacterial diarrhea is still disputed. Aeromonas-associated diarrhea is a phenomenon occurring worldwide; however, the exact prevalence of Aeromonas infections on a global scale is unknown. METHODOLOGY/PRINCIPAL FINDINGS: The prevalence and virulence potential of Aeromonas in patients suffering from diarrhea in Israel was studied using molecular methods. 1,033 diarrheal stools were sampled between April and September 2010 and Aeromonas species were identified in 17 (∼2% patients by sequencing the rpoD gene. Aeromonas species identity and abundance was: A. caviae (65%, A. veronii (29% and Aeromonas taiwanensis (6%. This is the first clinical record of A. taiwanensis as a diarrheal causative since its recent discovery from a wound infection in a patient in Taiwan. Most of the patients (77% from which Aeromonas species were isolated were negative for any other pathogens. The patients ranged from 1 to 92 years in age. Aeromonas isolates were found to possess different virulence-associated genes: ahpB (88%, pla/lip/lipH3/apl-1 (71%, act/hlyA/aerA (35%, alt (18%, ast (6%, fla (65%, lafA (41%, TTSS ascV (12%, TTSS ascF-ascG (12%, TTSS-dependent ADP-ribosylating toxins aexU (41% and aexT (6% in various combinations. Most of the identified strains were resistant to beta-lactam antibiotics but susceptible to third-generation cephalosporin antibiotics. CONCLUSIONS: Aeromonas may be a causative agent of diarrhea in patients in Israel and therefore should be included in routine bacteriological screenings.

Successful Fitting of a Complete Maxillary Denture in a Patient with Severe Alzheimer’s Disease Complicated by Oral Dyskinesia

Full Text Available There is an increasing population of elderly patients suffering from Alzheimer’s disease (AD, the most common form of dementia. In dentistry, a critical problem associated with these patients is the use of a new denture, as AD patients often refuse dental management and are disturbed by minor changes in their oral environment. Some AD patients have further complications associated with oral dyskinesia, a movement disorder that can make dental management difficult, including the stability of a complete denture. In this case, we successfully fitted a complete maxillary denture using modified bilateral balanced occlusion after multiple tooth extractions under intravenous sedation in a 66-year-old woman with severe AD complicated by oral dyskinesia. Following treatment, her appetite and food intake greatly improved. Providing a well-fitting complete denture applied by modified bilateral balanced occlusion, which removes lateral interference using zero-degree artificial teeth for movement disorder of the jaw in patients with severe AD complicated by oral dyskinesia, helps improve oral function.

Long-term outcome of lobar ablation in differentiated thyroid cancer (DTC): a comparative study with patients of completion thyroidectomy

International Nuclear Information System (INIS)

Santra, Amburanjan; Maharjan, S.; Bal, C.

2010-01-01

Full text: Completion thyroidectomy (CT) is usually recommended after partial surgery in patients with differentiated thyroid cancer. Radioiodine lobar ablation (RAILA) is an easy alternative and avoids complications that might be associated with re-surgery. But its effectiveness in terms of long-term outcome and recurrence free survival is yet to be established. This study was aimed to compare long term outcome of RAILA with that of completion thyroidectomy. Materials and Methods: A retrospective analysis was done from the case records of patients treated in our thyroid clinic for last 25 years. Records of all patients of RAILA (364) and CT (372) were analyzed. Complete ablation rate, cumulative dose needed for complete ablation, Recurrence rate and recurrence free survival was estimated in each group. Comparison was made between two groups by statistical method. Results: There was 73% ablation rate at 1st dose of RAILA itself. Second dose in LA and first dose of remnant ablation after CT is comparable (92% and 93% respectively). Cumulative dose to achieve 100% ablation rate is more for RAILA group. Seven patients developed recurrence in RAILA group, compared to 14 in CT group. No statistically significant difference was noted between recurrence rate and recurrence free survival between two groups. Conclusion: Radioiodine Lobar ablation is a safe, effective and less costly alternative to completion thyroidectomy in patients with differentiated thyroid cancer with comparable long term outcome like recurrence rate and recurrence free survival

Objective: To evaluate lung fissures completeness, post-treatment radiological response and quantitative CT analysis (QCTA) in a population of severe emphysematous patients submitted to endobronchial valves (EBV) implantation. Materials and Methods: Multi-detectors CT exams of 29 patients were studied, using thin-section low dose protocol without contrast. Two radiologists retrospectively reviewed all images in consensus; fissures completeness was estimated in 5% increments and post-EBV radiological response (target lobe atelectasis/volume loss) was evaluated. QCTA was performed in pre and post-treatment scans using a fully automated software. Results: CT response was present in 16/29 patients. In the negative CT response group, all 13 patients presented incomplete fissures, and mean oblique fissures completeness was 72.8%, against 88.3% in the other group. QCTA most significant results showed a reduced post-treatment total lung volume (LV) (mean 542 ml), reduced EBV-submitted LV (700 ml) and reduced emphysema volume (331.4 ml) in the positive response group, which also showed improved functional tests. Conclusion: EBV benefit is most likely in patients who have complete interlobar fissures and develop lobar atelectasis. In patients with no radiological response we observed a higher prevalence of incomplete fissures and a greater degree of incompleteness. The fully automated QCTA detected the post-treatment alterations, especially in the treated lung analysis. (author)

Marshall, Andrea P; Lemieux, Margot; Dhaliwal, Rupinder; Seyler, Hilda; MacEachern, Kristen N; Heyland, Daren K

2017-06-01

Critically ill patients are at increased risk of developing malnutrition-related complications because of physiological changes, suboptimal delivery, and reduced intake. Strategies to improve nutrition during critical illness recovery are required to prevent iatrogenic underfeeding and risk of malnutrition. The purpose of this study was to assess the feasibility and acceptability of a novel family-centered intervention to improve nutrition in critically ill patients. A 3-phase, prospective cohort feasibility study was conducted in 4 intensive care units (ICUs) across 2 countries. Intervention feasibility was determined by patient eligibility, recruitment, and retention rates. The acceptability of the intervention was assessed by participant perspectives collected through surveys. Participants included family members of the critically ill patients and ICU and ward healthcare professionals (HCPs). A total of 75 patients and family members, as well as 56 HCPs, were enrolled. The consent rate was 66.4%, and 63 of 75 (84%) of family participants completed the study. Most family members (53/55; 98.1%) would recommend the nutrition education program to others and reported improved ability to ask questions about nutrition (16/20; 80.0%). Family members viewed nutrition care more positively in the ICU. HCPs agreed that families should partner with HCPs to achieve optimal nutrition in the ICU and the wards. Health literacy was identified as a potential barrier to family participation. The intervention was feasible and acceptable to families of critically ill patients and HCPs. Further research to evaluate intervention impact on nutrition intake and patient-centered outcomes is required.

Long-Term Follow-up of a Patient with Traumatic Brain Injury Using Diffusion Tensor Imaging

This case report describes a patient who sustained severe head trauma with diffuse axonal injury (DAI). Examination with magnetic resonance diffusion tensor imaging (MR-DTI), 6 days post-injury, showed a severe reduction in fractional anisotropy (FA) in the rostral pons containing the corticospinal tract, which correlated to the patient's severe hemiparesis. By 18 months post-accident, the patient had recovered completely and conventional MRI showed no pathology. However, although her FA values in the rostral pons had increased, they were still not normalized. It seems that a complete normalization of the FA values is not required to achieve clinical recovery, and that MR-DTI seems to be more sensitive to DAI compared to conventional MRI

Method of recovering hydrocarbons from oil shale

Energy Technology Data Exchange (ETDEWEB)

Walton, D.K.; Slusser, M.S.

1970-11-24

A method is described for recovering hydrocarbons from an oil-shale formation by in situ retorting. A well penetrating the formation is heated and gas is injected until a pressure buildup within the well is reached, due to a decrease in the conductivity of naturally occurring fissures within the formation. The well is then vented, in order to produce spalling of the walls. This results in the formation of an enlarged cavity containing rubberized oil shale. A hot gas then is passed through the rubberized oil shale in order to retort hydrocarbons and these hydrocarbons are recovered from the well. (11 claims)

Clinical comparison of masticatory performance and electromyographic activity of patients with complete dentures, overdentures, and natural teeth.

Science.gov (United States)

Rissin, L; House, J E; Manly, R S; Kapur, K K

1978-05-01

In this study, which is the first of its kind, it has been shown that overdenture patients, when compared to complete denture patients, while chewing a test food for a constant number of strokes, expended an equivalent amount of muscle effort, chewed more slowly and efficiently, and evidenced significantly better masticatory performance by producing an increased volume of fine test food particles. These findings provide a sound justification for the extra effort required to retain some natural teeth to provide overdenture services to patients. The fact that patients can masticate food more efficiently with overdentures than with complete dentures justifies the increased cost and time involved in their construction. The longitudinal effects that overdentures have on the basic physiopathologic processed involved in the progression of ridge resorption and the advantages of maintaining periodontal proprioception also should be studied.

Complete colonic duplication is a very rare congenital anomaly that may have different presentations according to its location and size. Complete colonic duplication can occur in 15% of gastrointestinal duplication. We report two cases of complete colonic duplications, and their characteristics. We present two patients with complete colonic duplication with different types and presentations. Case 1: A 2- year old boy presented to the clinic with abdominal protrusion, difficulty to defecate, chronic constipation and mucosal prolaps covered bulging (rectocele) since he was 6 months old. The patient had palpable pelvic mass with doughy consistency. Rectal exam confirmed perirectal mass with soft consistency. The patient underwent a surgical operation that had total tubular colorectal duplication with one blind end and was treated with simple fenestration of distal end, and was discharged without complication. After two years follow up, he had normal defecation and good weight gain. Case 2: A 2 -day old infant was referred with imperforate anus and complete duplication of recto-sigmoid colon, diphallus, double bladder, and hypospadiasis. After clinical and paraclinical investigations, he underwent operations in several stages in different periods, and was discharged without complications. After four years follow up, he led a normal life. The patients with complete duplication have to be examined carefully because of the high incidence of other systemic anomalies. Treatment includes simple resection of distal common wall, fenestration, and repair other associated anomalies.

2013-11-01

To systematically review clinical outcomes of different occlusal designs of complete dentures. Using a various key words, an electronic search of clinical trials published in English and Chinese literature was performed from four databases: Medline/PubMed, EMBASE, Cochrane Library, and CBM. Furthermore, a manual searching of the relevant journals and the bibliographies of reviews was performed. General satisfaction, masticatory ability, retention, and stability were major criteria for the evaluation of the outcomes. Studies met these criteria were selected for a full-text reading. The whole processes were performed by two reviewers independently. This systematic review started with 1030 articles, which were finally narrowed down to seven, according to the inclusion criteria. The following occlusal designs were included and analyzed: anatomic occlusion, balanced occlusion, canine guidance occlusion, lingualized occlusion, monoplane occlusion, and bilateral-balanced and canine-guided design. Three of the seven studies showed that lingualized occlusion had ratings of higher patients' satisfaction than other occlusion designs. On the other hand, the canine-guided occlusion dentures demonstrated equal or better clinical performances than bilateral-balanced dentures. Because of the heterogeneity and bias of the studies, it was not possible to analyze the data statistically. Lingualized occlusion and canine-guided occlusion can be successfully applied in the fabrication of complete dentures. Canine guided occlusion has also been shown to be satisfactory. More well-controlled randomized trials are needed regarding canine-guided occlusion and the relationship between alveolar ridge resorption, different occlusal schemes and patient satisfaction. The conventional prosthodontic wisdom that complete dentures require a balanced occlusal design is not supported by the included literature. A suitable occlusal scheme would be a critical factor for a successful complete denture

Ceftaroline is a new parenteral cephalosporin agent with excellent activity against methicillin-sensitive (MSSA) and resistant strains of Staphylococcus aureus (MRSA). Critically ill surgical patients are susceptible to infection, often by multi-drug-resistant pathogens. The activity of ceftaroline against such pathogens has not been described. Three hundred thirty-five consecutive microbial isolates were collected from surgical wounds or abscesses, respiratory, urine, and blood cultures from patients in the surgical intensive care unit (SICU) of a major tertiary medical center. Using Clinical and Laboratory Standards Institute (CLSI) standard methodology and published breakpoints, all aerobic, facultative anaerobic isolates were tested against ceftaroline and selected comparative antimicrobial agents. All staphylococcal isolates were susceptible to ceftaroline at a breakpoint of ≤1.0 mcg/mL. In addition, ceftaroline exhibited excellent activity against all streptococcal clinical isolates and non-ESBL-producing strains of Enterobacteriaceae (93.5%) recovered from SICU patients. Ceftaroline was inactive against ESBL-producing Enterobacteriaceae, Pseudomonas aeruginosa, vancomycin-resistant enterococci, and selective gram-negative anaerobic bacteria. At present, ceftaroline is the only cephalosporin agent that is active against community and healthcare-associated MRSA. Further studies are needed to validate the benefit of this novel broad-spectrum anti-infective agent for the treatment of susceptible serious infections in the SICU patient population.

Espinola M, Daniela; Espinola M, Daniela; Bellolio R, Felipe; Gellona V, Jose; Bustos C, Mariza; Zuniga D, Alvaro

2013-01-01

Background: The standard treatment of locally advanced rectal cancer (RC) of the middle and lower third of the rectum is neoadjuvant chemoradiotherapy (XRQT) follow by oncologic resection. After this treatment in 15-25% of the cases, the pathologist reports complete pathological response (pCR). Aim: To describe demographic, clinical and survival data of patients with pCR undergoing chemoradiotherapy and radical resection for RC. Material and Methods: Historic cohort study. In a prospectively maintained database between 2000 and 2010, we identified patients with RC, who underwent neoadjuvant chemoradiotherapy according to protocol, followed by radical resection. The preoperative staging was obtained by clinical examination, endoscopy, rectal ultrasound, CT scan of chest, abdomen and pelvis and pelvic MRI. Demographic data, tumor location, time between the end of XRTQ and surgery, postoperative staging (according AJCC) and survival, were collected. Results: 119 patients received preoperative XRTQ, 65% male, with a mean age of 58 years. The most frequent tumor site was the lower third (63%). Surgery was performed 8 weeks after the end of XRTQ. Of 119 patients with XRTQ, 15.1% had a pCR. Overall survival was 75%, and cancer-specific survival was 80.4% at 5 years in patients without pCR. For patients with pCR, the 5 year survival estimates for overall and cancer specific survival was 100%. We did not identify factors associated with pCR. Conclusions: In this study, pCR was comparable to other larger series reported elsewhere. No factors associated with pCR were identified

A theoretical framework for understanding recovered memory experiences.

Science.gov (United States)

Brewin, Chris R

2012-01-01

If recovered memory experiences appear counter-intuitive, this is in part due to misconceptions about trauma and memory, and to a failure to adopt a comprehensive model of memory that distinguishes personal semantic memory, autobiographical event memory, and memory appraisal. Memory performance is generally superior when events, including traumas, are central to identity. Prolonged trauma in childhood, however, can produce severe identity disturbances that may interfere with the encoding and later retrieval of personal semantic and autobiographical event information. High levels of emotion either at encoding or recall can also interfere with the creation of coherent narrative memories. For example, high levels of shock and fear when memories are recovered unexpectedly may lead to the experience of vivid flashbacks. Memory appraisals may also influence the sense that an event has been forgotten for a long time. Recovered memories, although unusual, do not contradict what we know about how memory works.

We establish a priori conditions for a Gel'fand-Levitan (GL) integral using some results of the Fredholm theory. As consequence, we obtain a recovering formula for the potential of the coupled nonlinear Schroedinger equations. The remarkable fact is that the recovering formula is given in terms of the solutions of a classical GL-integral equation. (author)

Method of recovering phosphoric acid type decontaminating electrolytes by electrodeposition

International Nuclear Information System (INIS)

Sasaki, Takashi; Wada, Koichi; Kobayashi, Toshio.

1985-01-01

Purpose: To recoving phosphoric acid type highly concentrated decontaminating liquid used for the electrolytic decontamination of contaminated equipments, components, etc in nuclear power plants or the like through electrodeposition by diaphragm electrolysis. Method: Before supplying phosphoric acid decontaminating liquid at high concentration used in the electrolytic decontaminating step to an electrodeposition recovering tank, phosphoric acid in the decontaminating electrolyte is extracted with solvents and decomposed liquid extracts (electrolyte reduced with the phosphoric acid component) are supplied to the cathode chamber of the electrodeposition recovering tank, where phosphoric acid is back-extracted with water from the solvents after extraction of phosphoric acid. Then, the back-extracted liquids (aqueous phosphoric acid solution scarcely containing metal ions) are sent to the anode chamber of the electrodeposition recovering tank. Metal ions in the liquid are captured by electrodeposition in the cathode chamber, as well as phosphoric acid in the liquids is concentrated to the initial concentration of the electrolyte in the anode chamber for reuse as the decontaminating electrolyte. As the phosphoric acid extracting agent used in the electrodeposition recovering step for the decontaminating electrolyte, water-insoluble and non-combustible tributyl phosphate (TBP) is most effective.

Healing the incest wound: a treatment update with attention to recovered-memory issues.

Science.gov (United States)

Courtois, C A

1997-01-01

This article provides an updated treatment model for adults who report having experienced incestuous abuse in childhood. It integrates psychodynamic, traumatic stress, developmental and feminist formulations, accords greater emphasis to object relations and self-psychology perspectives, includes more attention to dissociative reactions, and utilizes more cognitive-behavioral interventions. It is also responsive to issues raised in the recovered/false memory controversy. This holistic model is sequenced, paced, and titrated according to the patient's characterological structure, ego strength, and needs as well as the range and severity of presenting problems and life difficulties. Special consideration is given to issues pertaining to memory and the maintenance of a neutral stance by the therapist, especially in the case of recovered rather than continuous memories and/or suspicions rather than actual knowledge of abuse. Contemporary perspectives regarding some of the unique transference, countertransference, and vicarious traumatization issues with this population and their potential impact on treatment are also discussed.

Solid recovered fuels in the steel industry.

By using waste materials as alternative fuels in metallurgical plants it is possible to minimize the traditionally used reducing agents, such as coke, coal, oil or natural gas. Moreover, by using waste materials in the metallurgical industry it is feasible to recover these materials as far as possible. This also represents another step towards environmental protection because carbon dioxide emissions can be reduced, if the H(2) content of the waste material is greater in comparison with that of the substituted fuel and the effects of global warming can therefore be reduced. In the present article various solid recovered fuels and their applications in the metallurgical industry are detailed.

Simultaneous tensor decomposition and completion using factor priors.

Chen, Yi-Lei; Hsu, Chiou-Ting; Liao, Hong-Yuan Mark

2014-03-01

The success of research on matrix completion is evident in a variety of real-world applications. Tensor completion, which is a high-order extension of matrix completion, has also generated a great deal of research interest in recent years. Given a tensor with incomplete entries, existing methods use either factorization or completion schemes to recover the missing parts. However, as the number of missing entries increases, factorization schemes may overfit the model because of incorrectly predefined ranks, while completion schemes may fail to interpret the model factors. In this paper, we introduce a novel concept: complete the missing entries and simultaneously capture the underlying model structure. To this end, we propose a method called simultaneous tensor decomposition and completion (STDC) that combines a rank minimization technique with Tucker model decomposition. Moreover, as the model structure is implicitly included in the Tucker model, we use factor priors, which are usually known a priori in real-world tensor objects, to characterize the underlying joint-manifold drawn from the model factors. By exploiting this auxiliary information, our method leverages two classic schemes and accurately estimates the model factors and missing entries. We conducted experiments to empirically verify the convergence of our algorithm on synthetic data and evaluate its effectiveness on various kinds of real-world data. The results demonstrate the efficacy of the proposed method and its potential usage in tensor-based applications. It also outperforms state-of-the-art methods on multilinear model analysis and visual data completion tasks.

Cortex-dependent recovery of unassisted hindlimb locomotion after complete spinal cord injury in adult rats

Science.gov (United States)

Manohar, Anitha; Foffani, Guglielmo; Ganzer, Patrick D; Bethea, John R; Moxon, Karen A

2017-01-01

After paralyzing spinal cord injury the adult nervous system has little ability to ‘heal’ spinal connections, and it is assumed to be unable to develop extra-spinal recovery strategies to bypass the lesion. We challenge this assumption, showing that completely spinalized adult rats can recover unassisted hindlimb weight support and locomotion without explicit spinal transmission of motor commands through the lesion. This is achieved with combinations of pharmacological and physical therapies that maximize cortical reorganization, inducing an expansion of trunk motor cortex and forepaw sensory cortex into the deafferented hindlimb cortex, associated with sprouting of corticospinal axons. Lesioning the reorganized cortex reverses the recovery. Adult rats can thus develop a novel cortical sensorimotor circuit that bypasses the lesion, probably through biomechanical coupling, to partly recover unassisted hindlimb locomotion after complete spinal cord injury.

The completeness of the fossil record of plesiosaurs, marine reptiles from the Mesozoic

Full Text Available Plesiosaurs were a highly successful group of marine reptiles occurring worldwide in the Jurassic and Cretaceous, but to date few studies have focused on their preservation through time. Here, we conduct the first detailed assessment of the quality of the plesiosaur fossil record. Data was compiled for 178 specimens representing 114 valid species. For each species we calculated the character completeness metric (CCM: percentage of phylogenetic characters from a cladistic dataset that can be scored for that species and the skeletal completeness metric (SCM: percentage of the overall skeleton that is preserved for that species. Average CCM and SCM values were calculated for individual geological stages. A strong significant positive correlation was recovered between CCM and SCM, suggesting that the two metrics are recording the same signal, at least for this clade. Although a significant correlation between changes in sea level and changes in plesiosaur completeness was not recovered, an underlying negative relationship may be present but obscured by poorly sampled time bins. Plesiosaur completeness though time is not significantly correlated with that for contemporary terrestrial groups (sauropods, pterosaurs, birds, but is significantly correlated with that for ichthyosaurs, suggesting common controls on skeletal preservation in the marine realm. Significantly higher median completeness values in plesiosaurs and ichthyosaurs than in contemporary terrestrial groups support the hypothesis that the marine tetrapod fossil record is more complete than that of terrestrial tetrapods. A collector’s curve for plesiosaurs shows a generally slow constant rate of discovery from the latter part of the 19th century until the 1990s, at which point the rate of discovery increased substantially and shows no sign of slowing.

2013-01-01

Full Text Available Background: Hypokalemic paralysis is characterized by episodes of acute muscle weakness associated with hypokalemia. In this study, we evaluated the possible etiological factors in patients of hypokalemic paralysis. Materials and Methods: We reviewed the records of 29 patients who were admitted with a diagnosis of hypokalemic paralysis. Modified Guillain-Barre΄ Syndrome disability scale was used to grade the disability. Results: In this study, 15 (51.7% patients had secondary causes of hypokalemic paralysis and 14 patients (42.3% had idiopathic hypokalemic paralysis. Thyrotoxicosis was present in six patients (20.6%, dengue infection in four patients (13.7%, distal renal tubular acidosis in three patients (10.3%, Gitelman syndrome in one patient (3.4%, and Conn′s syndrome in one patient (3.4%. Preceding history of fever and rapid recovery was seen in dengue infection-induced hypokalemic paralysis. Approximately 62% patients had elevated serum creatinine phosphokinase. All patients had recovered completely following potassium supplementation. Patients with secondary causes were older in age, had significantly more disability, lower serum potassium levels, and took longer time to recover. Conclusion: In conclusion, more than half of patients had secondary causes responsible for hypokalemic paralysis. Dengue virus infection was the second leading cause of hypokalemic paralysis, after thyrotoxicosis. Presence of severe disability, severe hypokalemia, and a late disease onset suggested secondary hypokalemic paralysis.

Remote sensing images are seriously degraded by multiple scattering and bad weather. Through the analysis of the radiative transfer procedure in atmosphere, an image atmospheric degradation model considering the influence of atmospheric absorption multiple scattering and non-uniform distribution is proposed in this paper. Based on the proposed model, a novel recovering method is presented to eliminate atmospheric degradation. Mean-shift image segmentation and block-wise deconvolution are used to reduce time cost, retaining a good result. The recovering results indicate that the proposed method can significantly remove atmospheric degradation and effectively improve contrast compared with other removal methods. The results also illustrate that our method is suitable for various degraded remote sensing, including images with large field of view (FOV), images taken in side-glance situations, image degraded by atmospheric non-uniform distribution and images with various forms of clouds.

Rationale. The imaging methods are more and more used in the clinical process of modern dentistry. Once the implant based treatment alternatives are nowadays seen as being the standard of care in edentulous patients, these techniques must be integrated in the complete denture treatment. Aim. The study presents some evaluation techniques for the edentulous patient treated by conventional dentures or mini dental implants (mini SKY Bredent) overdentures, using the profile teleradiography. These offer data useful for an optimal positioning of the artificial teeth and the mini dental implants, favoring to obtain an esthetic and functional treatment outcome. We proposed also a method to conceive a simple surgical guide that allows the prosthetically driven implants placement. Material and method. Clinical case reports were made, highlighting the importance of cephalometric evaluation on lateral teleradiographs in complete edentulous patients. A clinical case that gradually reports the surgical guide preparation (Bredent silicon radio opaque), in order to place the mini dental implants in the best prosthetic and anatomic conditions, was presented. Conclusions. The profile teleradiograph is a useful tool for the practitioner. It allows establishing the optimal site for implant placement, in a good relation with the overdenture. The conventional denture can be easily and relatively costless transformed in a surgical guide used during implant placement. PMID:23599828

Assistant professor, Department of surgery, Faculty of medicine, Babol University of medical sciences Abstract Background: Acute appendicitis is a completely known disease but for many physicians chronic appendicitis is unknown and some of them don believe in it. Although the number of people suffer from chronic appendicitis is much fewer than those who suffer from acute appendicitis, we shouldn ignore it. Clinical symptoms for these patients are chronic, longtime and recurrent abdominal pain, which is usually in the right lower quadrant of the abdomen. In the Para clinical examinations there isn any considerable pathological problem (in urine, stool, and sonography of the abdomen and pelvis. By recognizing appendicitis and appendectomy, the symptoms will be vanished and the patients will recover. Case presentation: The case was a 57-year-old man who has complained from chronic abdominal pain in the RLQ area since 15years ago. No pathological problem had been found in all diagnostic process. Conclusion: The problem was diagnosed as the chronic appendicitis and he underwent the appendectomy by laparoscopic procedure and was completely recovered.

The non-specific immunological parameters of 37 patients with malignant brain tumors were analysed by means of 1) purified protein derivative (PPD) skin test, 2) lymphocyte counts, and 3) phytohemagglutinin (PHA) blastogenesis. The PPD skin reaction and PHA blastogenesis were already depressed preoperatively in patients with malignant brain tumors as compared to those in normal controls. When radiotherapy was confined to the head, lymphocyte counts and PHA blastogenesis were further depressed, but gradually recovered to preoperative levels within 6 months after the completion of radiotherapy. In the cases with medulloblastoma and germinoma who received whole cerebrospinal axis irradiation, lymphocyte counts and PHA blastogenesis were more markedly depressed and took more than 6 months after completion of the radiotherapy to recover to their preoperative levels. The result of the PPD skin test, on the other hand, was not affected and was rather enhanced by radiotherapy, showing a marked dissociation from the changes in lymphocyte counts and PHA blastogenesis. The results of PPD skin test on discharge from hospital were relatively well correlated with the prognosis of the patients. The profound immunosuppressive influence of radiotherapy and the natural course of recovery should be taken into consideration if any immunological treatments are to be undertaken with or after the course of radiotherapy.

Stage IV colorectal cancer is usually an incurable disease. However, patients with resectable metastases have 5-year disease-free survival rates of up to 30%. Even with primarily irresectable disease, cure can be achieved in patients who become operable after neoadjuvant treatment. To improve the prognosis of these patients, highly effective neoadjuvant regimens need to be developed. Here, we report the case of a 62-year-old male patient who had been diagnosed with International Union against Cancer (UICC) stage III colon cancer 7 years previously and now presented with a large, irresectable liver metastasis and enlarged perihepatic lymph nodes. After neoadjuvant treatment with cetuximab, bevacizumab and XELOX, the patient showed a complete remission and underwent surgery. Histopathologically, the resected tissue and lymph nodes were free of residual tumor. To our knowledge, this is the first report of a complete pathological response in a patient with irresectable colorectal cancer after intensive chemotherapy/anti-EGFR/ VEGF antibody therapy. This combination regimen may help to improve the survival rates for patients with irresectable disease. Copyright 2008 S. Karger AG, Basel.

There are many causes of conductive hearing loss. Otoplasty is a commonly performed cosmetic surgery to correction for prominent ear. We discussed an unusual cause of conductive hearing loss, bilateral complete meatal obstruction following otoplasty, in this article. This complication was probably due to unsuitable placement of the Furnas sutures. In the literature, as a cause of conductive hearing loss, unilateral complete meatal obstruction has been described rarely, but bilateral complete obstruction has not been defined. Hearing loss recovered completely after revision surgery. Correct diagnosis, accurate preoperative or perioperative examination, choice of the proper technique and surgeon experience are essential for avoiding inadequate results or complications of otoplasty. The surgeon should be aware of the cartilage elasticity and suture techniques to avoid this complication.

Mandibular overdentures retained by a single implant placed in the midline of edentulous mandible have been reported to be more comfortable and function better than complete dentures. Although single-implant overdentures are still more costly than conventional complete dentures, there are a few studies which investigated whether mandibular single-implant overdentures are superior to complete dentures when patient general satisfaction is compared. The aim of this study is to assess patient general satisfaction with mandibular single-implant overdentures and complete dentures. This study is a randomized crossover trial to compare mandibular single-implant overdentures and complete dentures in edentulous individuals. Participant recruitment is ongoing at the time of this submission. Twenty-two participants will be recruited. New mandibular complete dentures will be fabricated. A single implant will be placed in the midline of the edentulous mandible. The mucosal surface of the complete denture around the implant will be relieved for 3 months. The participants will then be randomly allocated into 2 groups according to the order of the interventions; group 1 will receive single-implant overdentures first and will wear them for 2 months, followed by complete dentures for 2 months. Group 2 will receive the same treatments in a reverse order. After experiencing the 2 interventions, the participants will choose one of the mandibular prostheses, and yearly follow-up visits are planned for 5 years. The primary outcome of this trial is patient ratings of general satisfaction on 100 mm visual analog scales. Assessments of the prostheses and oral health-related quality of life will also be recorded as patient-reported outcomes. The secondary outcomes are cost and time for treatment. Masticatory efficiency and cognitive capacity will also be recorded. Furthermore, qualitative research will be performed to investigate the factors associated with success of these mandibular

Highlights: • Some cancer cells recover from severe damage that causes cell death in majority of cells. • Damage-Recovered (DR) cancer cells show reduced mitochondria, mDNA and mitochondrial enzymes. • DR cells show increased aerobic glycolysis, ATP, cell proliferation, and resistance to damage. • DR cells recovered from in vivo damage also show increased glycolysis and proliferation rate. - Abstract: Instead of relying on mitochondrial oxidative phosphorylation, most cancer cells rely heavily on aerobic glycolysis, a phenomenon termed as “the Warburg effect”. We considered that this effect is a direct consequence of damage which persists in cancer cells that recover from damage. To this end, we studied glycolysis and rate of cell proliferation in cancer cells that recovered from severe damage. We show that in vitro Damage-Recovered (DR) cells exhibit mitochondrial structural remodeling, display Warburg effect, and show increased in vitro and in vivo proliferation and tolerance to damage. To test whether cancer cells derived from tumor microenvironment can show similar properties, we isolated Damage-Recovered (T{sup DR}) cells from tumors. We demonstrate that T{sup DR} cells also show increased aerobic glycolysis and a high proliferation rate. These findings show that Warburg effect and its consequences are induced in cancer cells that survive severe damage.

Here we report a case of a 70-year-old man who received adjuvant chemotherapy with fluorouracile, folinic acid and oxaliplatin after a left hemicolectomy for a stage IIIb adenocarcinoma in May 2009. During follow-up he de-veloped abdominal lymphnodes metastases evidenced by positron emission tomography- computed tomography (PET-CT) scan and increase of carcinoembryonic antigen (CEA) level. Chemotherapy with capecitabine, oxaliplatin and bevacizumab was started in April 2012. Restaging showed a complete response and normalization of CEA. The patient received maintenance therapy with bevacizumab which was stopped in December 2013 for patient choice. In October 2014, a new increase in CEA was documented and PET-CT scan showed lung metastases. Analysis of RAS status revealed the absence of mutations, then the patient started a second-line chemotherapy with fluorouracile, folinic acid, irinotecan (folfiri) and panitumumab achieving, in January 2015, a complete response and normalization of CEA. Thereafter, folfiri was discontinued for toxicity; furthermore, upon the third occurrence of a grade 3 dermatologic toxicity, panitumumab was continued from June 2015 at 60% of the original dose and it was administered every three weeks. Until presentation of this case, the patient maintains a complete response, has no symptoms of disease and CEA is normal. Interestingly, this patient presented a high proportion of circulating natural killer (NK) cells (35.1%) with high cytotoxic activity against tumor cells. Study on the role of NK in patients with advanced colorectal cancer are ongoing.

Full Text Available Miscanthus (Miscanthus sp. Family: Poaceae was hot-water extracted (two h, at 160 °C at three scales: laboratory (Parr reactor, 300 cm3, intermediate (M/K digester, 4000 cm3, and pilot (65 ft3-digester, 1.841 × 106 cm3. Hot-water extracted miscanthus, hydrolyzate, and lignin recovered from hydrolyzate were characterized and evaluated for potential uses aiming at complete utilization of miscanthus. Effects of scale-up on digester yield, removal of hemicelluloses, deashing, delignification degree, lignin recovery and purity, and cellulose retention were studied. The scale-dependent results demonstrated that before implementation, hot-water extraction (HWE should be evaluated on a scale larger than a laboratory scale. The production of energy-enriched fuel pellets from hot-water extracted miscanthus, especially in combination with recovered lignin is recommended, as energy of combustion increased gradually from native to hot-water extracted miscanthus to recovered lignin. The native and pilot-scale hot-water extracted miscanthus samples were also subjected to enzymatic hydrolysis using a cellulase-hemicellulase cocktail, to produce fermentable sugars. Hot-water extracted biomass released higher amount of glucose and xylose verifying benefits of HWE as an effective pretreatment for xylan-rich lignocellulosics. The recovered lignin was used to prepare a formaldehyde-free alternative to phenol-formaldehyde resins and as an antioxidant. Promising results were obtained for these lignin valorization pathways.

Objective: To find out the optimal pacing localization by comparing different pacing positions of the right ventricle in brady-cardiacarrhythmia patients with complete right bundle branch block. Methods: DDD type of double lumen permanent pacemaker was implanted in each of the 8 cases of sick sinus syndrome (SSS) and/or III degree atrioventricular block (III degree AVB) with complete right bundle branch block in normal heart function or class I. For each patient, four pacing positions in right ventricle were compared and the QRS pacing durations were recorded. The position with the shortest the QRS duration was chosen as the permanent pacing position. Heart function, chest X-rays and left ventricle ejection fraction (LVEF) were followed up after the operation. Results: In all the 8 cases, the posterior septum of the right ventricle were chosen as the permanent pacing position, with the shorter pacing QRS duration than that of pre-operation (P<0.05) and other pacing positions of the right ventricle. All parameters of this permanent pacing position were within the normal range. During the follow-up of 6-36 months, no abnormity was found in cardiac functions. Conclusion: In brady-cardiacarrhythmia patients with complete right bundle branch block, the implantation of permanent pacemaker should be at the junction region of inlet and outlet tracts, of the posterior septum of the right ventricle with ideal physiological function.

Patients with complete paraplegia after spinal cord injury (SCI) are unable to stand or walk on their own. Standing exercise decreases the risk of decubitus ulcers, osteoporosis, and joint deformities in patients with SCI. Conventional gait training for complete paraplegia requires excessive upper limb usage for weight bearing and is difficult in cases of complete quadriplegia. The purpose of this study was to describe voluntary ambulation triggered by upper limb activity using the Hybrid Assistive Limb® (HAL) in patients with complete quadri/paraplegia after chronic SCI. Four patients (3 men, 1 woman) were enrolled in this study. The mean patient age ± standard deviation was 37.2 ± 17.8 (range, 20-67) years. Clinical evaluation before intervention revealed the following findings: case 1, neurological level C6, American Spinal Cord Injury Association impairment scale (AIS) grade B; case 2, T6, AIS A; case 3, T10 AIS A; and case 4, T11, AIS A. The HAL intervention consisted of 10 sessions. Each HAL session lasted 60-90 min. The HAL electrodes for hip and knee flexion-extension were placed on the anterior and posterior sides of the upper limbs contralaterally corresponding to each of the lower limbs. Surface electromyography (EMG) was used to evaluate muscle activity of the tensor fascia lata and quadriceps femoris (Quad) in synchronization with a Vicon motion capture system. The modified Ashworth scale (mAs) score was also evaluated before and after each session. All participants completed all 10 sessions. Cases 1, 2, and 3 demonstrated significant decreases in mAs score after the sessions compared to pre-session measurements. In all cases, EMG before the intervention showed no apparent activation in either Quad. However, gait phase dependent activity of the lower limb muscles was seen during voluntarily triggered ambulation driven by upper limb muscle activities. In cases 3 and 4, active contraction in both Quads was observed after intervention. These findings

Traffic speed data plays a key role in Intelligent Transportation Systems (ITS); however, missing traffic data would affect the performance of ITS as well as Advanced Traveler Information Systems (ATIS). In this paper, we handle this issue by a novel tensor-based imputation approach. Specifically, tensor pattern is adopted for modeling traffic speed data and then High accurate Low Rank Tensor Completion (HaLRTC), an efficient tensor completion method, is employed to estimate the missing traffic speed data. This proposed method is able to recover missing entries from given entries, which may be noisy, considering severe fluctuation of traffic speed data compared with traffic volume. The proposed method is evaluated on Performance Measurement System (PeMS) database, and the experimental results show the superiority of the proposed approach over state-of-the-art baseline approaches.

2015-01-01

A 17-year-old adolescent with ataxia-telangiectasia was scheduled to have laparoscopic colectomy for a resection of colon cancer. He had symptoms and signs of dyspnea, generalized dystonia, dysmetria, ataxia, and telangiectasia on the orbit. General anesthesia was performed, and rocuronium 30 mg was administered for muscle relaxation. Deep neuromuscular block (post-tetanic count: 0-8) was maintained for 95 minutes without additional rocuronium. On completion of surgery, sugammadex 80 mg was injected and train-of-four ratio was 0.93 at 210 seconds after administration. The tracheal tube was removed 5 min after the end of surgery. He recovered full spontaneous respiration and voluntary movements within 1 minute after extubation. After the surgery, he transferred to the intensive care unit and discharged 14 days after the surgery without any concrete problem. The reversal of rocuronium induced neuromuscular block by sugammadex was fast, complete, and recovered to the initial preoperative level of neuromuscular function in this patient. (author)

Reduction of energy cost and CO2 emission for the furnace using energy recovered from waste tail-gas

In this research, the waste tail gas emitted from petrochemical processes, e.g. catalytic reforming unit, catalytic cracking unit and residue desulfurization unit, was recovered and reused as a replacement of natural gas (NG). On-site experimental results show that both the flame length and orange-yellowish brightness decrease with more proportion of waste gas fuel added to the natural gas, and that the adiabatic temperature of the mixed fuel is greater than 1800 o C. A complete replacement of natural gas by the recovered waste gas fuel will save 5.8 x 10 6 m 3 of natural gas consumption, and 3.5 x 10 4 tons of CO 2 emission annually. In addition, the reduction of residual O 2 concentration in flue gases from 4% to 3% will save 1.1 x 10 6 m 3 of natural gas consumption, reduce 43.0% of NO x emission, and 1.3 x 10 3 tons of CO 2 emission annually. Thus, from the viewpoint of the overall economics and sustainable energy policy, recovering the waste tail gas energy as an independent fuel source to replace natural gas is of great importance for saving energy, reducing CO 2 emission reduction, and lowering environmental impact.

2004-05-01

To examine the effect of pre-surgical orthodontics on the outcome of the secondary alveolar bone grafting in the patients with complete cleft lip and palate. Sixteen complete cleft lip and palate patients (9 males and 7 females) with collapsed upper arch or severe mal-positioned upper incisors were selected. The cleft was not easily grafted because of the poor access. The total cleft sites were 22 (10 patients with UCLP and 6 patients with BCLP). The age range of the patients was from 8 to 22 years. Pre-surgical orthodontic treatment was mainly to expand the collapsed upper arch and correct the mal-positioned upper incisors. After the secondary alveolar bone grafting, the patients were followed up and anterior occlusal radiograph/intraoral panograph were taken regularly. The observation period was from 6 months to 4 years. Bergland criteria were used to evaluate the interdental septal height. Upper arch expansion and the correction of the mal-positioned upper incisors done by the orthodontic treatment made the bone grafting procedure easier. The clinically successful rate reached 86%. The severe upper arch collapse and mal-positioned upper incisors in the patients with complete cleft lip and palate should be corrected orthodontically before the secondary alveolar bone grafting.

Purpose: To define failure patterns and predictive factors in esophageal cancer patients who had a pathologic complete response (pCR) after preoperative concurrent chemoradiotherapy (PCRT). Methods and Materials: We performed a retrospective analysis of 61 esophageal cancer patients who were enrolled in prospective studies and showed pCR after PCRT. All of the patients had squamous cell carcinoma. Of the patients, 40 were treated with hyperfractionated radiotherapy (4,560 cGy in 28 fractions) with 5-fluorouracil (5-FU) and cisplatin (FP), and 21 patients received conventional fractionation radiotherapy with capecitabine and cisplatin (XP). Results: The median follow-up time was 45.2 months (range, 6.5-162.3 months). The 5-year overall survival (OS) and disease-free survival rates (DFS) were 60.2% and 80.4%, respectively. In univariate analysis, age and lymph node (LN) metastasis were poor prognostic factors for OS, and pretreatment weight loss (>2 kg) was a poor prognostic factor for DFS. In multivariate analysis, lymph node metastasis and pretreatment weight loss were independent prognostic factors for OS and DFS. Nine patients (15%) had disease recurrence. Of the nine patients, 5 patients had locoregional failure, 1 patients had distant metastasis, and 3 patients had distant and locoregional failure. In-field failure occurred in 5 patients; out-of-field failure occurred in 1 patient; both in-field and out-of-field failure occurred in 2 patients; and both marginal and out-of-field failure occurred in 1 patient. Conclusions: Even in pCR patients, the most common failure site was within the radiation field, which suggests that more efficient local treatment is needed. Tumor recurrence was more common in patients with older age and with pretreatment weight loss.

Patients with type 1 diabetes are classified into three subtypes in Japan: acute onset, fulminant and slowly progressive. Acute-onset type 1 diabetes would be equivalent to type 1A diabetes, the typical type 1 diabetes in Western countries. The insulin secretion capacity in Japanese patients with long-standing type 1A diabetes is unclear. The aim of the present study was to clarify the course of endogenous insulin secretion during long-term follow up and the factors associated with residual insulin secretion in patients with acute-onset type 1 diabetes (autoimmune). We retrospectively investigated endogenous insulin secretion capacity in 71 patients who fulfilled the diagnostic criteria for acute-onset type 1 diabetes (autoimmune) in Japan. To assess the residual insulin secretion capacity, we evaluated randomly measured C-peptide levels and the results of glucagon stimulation test in 71 patients. In the first year of disease, the child- and adolescent-onset patients had significantly more in residual insulin secretion than the adult-onset patients (34 patients in total). C-peptide levels declined more rapidly in patients whose age of onset was ≤18 years than in patients whose age of onset was ≥19 years. Endogenous insulin secretion capacity stimulated by glucagon was completely lost in almost all patients at >15 years after onset (61 patients in total). Most patients with acute-onset type 1 diabetes (autoimmune) completely lose their endogenous insulin secretion capacity during the disease duration in Japan. Age of onset might affect the course of insulin secretion. © 2017 The Authors.

Modified Pectoralis Major Tendon Transfer for Reanimation of Elbow Flexion as a Salvage Procedure in Complete Brachial Plexus Injury: A Case Report

Directory of Open Access Journals (Sweden)

S Taran

2013-03-01

Full Text Available Traumatic brachial plexus injuries rarely recover spontaneously and if the window period for neurotisation has elapsed, the only option for restoration of function lies in a salvage procedure. Many such salvage procedures have been described in the literature with variable functional results. We report the case of a 16-year-old boy who presented after unsuccessful treatment for a complete brachial plexus injury; we performed a pectoralis major tendon transfer to attain elbow flexion. Postoperatively, the elbow was splinted with flexion at 100°. After 4 weeks of immobilization the splint was removed and the patient could actively flex his elbow from 30° to 100°.

The Congress, in the National Energy Conservation and Policy Act of 1978 (NECPA), directed the Department of Energy to establish materials recovery targets for the metals and metal products, paper and allied products, rubber, and textile-mill-products industries. The targets were developed to provide incentives for using energy-saving recorded materials and to provied a yardstick for measuring progress and improvement in this endeavor. The NECPA indicates that the targets should represent the maximum technically and economically feasible increase in the use of energy-saving recovered materials that each industry can achieve progressively by January 1, 1987. Materials affected by recovered-materials targets include and are limited to aluminum, copper, lead, zinc, iron, steel, paper and associated products, textile-mill, products, and rubber. Using information gathered from the textile-mill-products industry and from other textile-relaed sources, DOE has developed recovered materials targets for that industry. This report presents those targets and their basis and justification. Following an overview of the textile industry, the chapters are: Textile-Mill-Products Industry Operations; Economic Analysis of the Textile-Mill-Products Industry; Governmental and Regulatory Influence on the US Textile Industry; Current Mill Use of Recovered Materials in the Textile-Mill-Products Industry; Limitations on the Use of Recovered Materials in the US Textile-Mill-Products Industry; Materials-Recovery Targets; and Government and Industry Actions That Could Increase the Use of Recovered Materials.

Full Text Available Purpose: We report on a case of unilateral acute syphilitic posterior placoid chorioretinitis (ASPPC with spontaneous resolution of the lesions, and discuss the role of an altered versus adequate immune response as the major pathogenic factor.Methods: We describe a case of acute loss of visual acuity (VA in the left eye (LE in a 55-year-old healthy man.Results: The patient presented with VA of 20/20 in the right eye (RE and hand movements in the LE. Fundoscopy revealed a large yellowish placoid macular lesion with subretinal fluid in the LE, with no abnormalities detected in the RE. Fluorescein angiography showed early hypofluorescence with late staining in the affected area. The clinical findings progressed fast during the first week, with extension of the initial lesion outside the temporal retinal vascular arcades and the appearance of new lesions in the same eye. The patient abandoned the clinic for two weeks with no treatment. When observed again, VA of the LE had recovered to 20/20 and the lesions had completely resolved. Venereal disease research laboratory (VDRL and fluorescent treponemal antibody absorption (FTA-ABS tests results were positive and HIV antibody test titers negative. The diagnosis of ASPPC in the left eye was made. The patient accepted treatment with penicillin G only 45 days after the initial presentation. AV remained stable at 20/20 both eyes and no relapses of the lesions were observed during this period without therapy. The patient was followed for 3 months after treatment. He remained asymptomatic and the ophthalmic examination was unremarkable. Conclusions: The pathogenesis of ASPPC is still not understood. Our case showed a sequential pattern of the chorioretinal lesions, with initial aggravation and complete posterior spontaneous resolution, showing the natural course of the disease. These findings suggest the presence of an adequate ocular immune response in patients with ASPPC, not supporting the initially

Nonoperative management for patients with rectal cancer who have achieved a clinical complete response after chemoradiotherapy is becoming increasingly important in recent years. However, the definition of and modality used for patients with clinical complete response differ greatly between institutions, and the role of endoscopic assessment as a nonoperative approach has not been fully investigated. This study aimed to investigate the ability of endoscopic assessments to predict pathological regression of rectal cancer after chemoradiotherapy and the applicability of these assessments for the watchful waiting approach. This was a retrospective comparative study. This study was conducted at a single referral hospital. A total of 198 patients with rectal cancer underwent preoperative endoscopic assessments after chemoradiotherapy. Of them, 186 patients underwent radical surgery with lymph node dissection. The histopathological findings of resected tissues were compared with the preoperative endoscopic findings. Twelve patients refused radical surgery and chose watchful waiting; their outcomes were compared with the outcomes of patients who underwent radical surgery. The endoscopic criteria correlated well with tumor regression grading. The sensitivity and specificity for a pathological complete response were 65.0% to 87.1% and 39.1% to 78.3%. However, endoscopic assessment could not fully discriminate pathological complete responses, and the outcomes of patients who underwent watchful waiting were considerably poorer than the patients who underwent radical surgery. Eventually, 41.7% of the patients who underwent watchful waiting experienced uncontrollable local failure, and many of these occurrences were observed more than 3 years after chemoradiotherapy. The number of the patients treated with the watchful waiting strategy was limited, and the selection was not randomized. Although endoscopic assessment after chemoradiotherapy correlated with pathological response

BRCA1/2 mutations influence the molecular characteristics and the effects of systemic treatment of breast cancer. This study investigates the impact of germline BRCA1/2 mutations on pathological complete response and prognosis in patients receiving neoadjuvant systemic chemotherapy. Breast cancer patients were tested for a BRCA1/2 mutation in clinical routine work and were treated with anthracycline-based or platinum-based neoadjuvant chemotherapy between 1997 and 2015. These patients were identified in the tumor registry of the Breast Center of the University of Erlangen (Germany). Logistic regression and Cox regression analyses were performed to investigate the associations between BRCA1/2 mutation status, pathological complete response, disease-free survival, and overall survival. Among 355 patients, 59 had a mutation in BRCA1 or in BRCA2 (16.6%), 43 in BRCA1 (12.1%), and 16 in BRCA2 (4.5%). Pathological complete response defined as "ypT0; ypN0" was observed in 54.3% of BRCA1/2 mutation carriers, but only in 22.6% of non-carriers. The adjusted odds ratio was 2.48 (95% CI 1.26-4.91) for BRCA1/2 carriers versus non-carriers. Patients who achieved a pathological complete response had better disease-free survival and overall survival rates compared with those who did not achieve a pathological complete response, regardless of BRCA1/2 mutation status. BRCA1/2 mutation status leads to better responses to neoadjuvant chemotherapy in breast cancer. Pathological complete response is the main predictor of disease-free survival and overall survival, independently of BRCA1/2 mutation status.

To identify factors that may influence parenting by mothers who are recovering from cocaine addiction. Exploratory descriptive, with in-depth unstructured interviews. Interviews were conducted in the woman's home or in a treatment center. A convenience sample of 11 women recovering from cocaine addiction who were mothers of children 3 years of age and younger. A content analysis was used to analyze the interview data. Two themes, personal/psychologic factors and environmental/contextual factors, and four subthemes emerged. They identify issues that may affect parenting by mothers being treated for cocaine addiction. Subthemes included low self-esteem, difficulty developing a maternal identity, isolation from friends and family, and chronic life stress. This study provides a better understanding of the sources contributing to vulnerability in the parenting role for mothers recovering from cocaine addiction and will assist nurses in providing care for these mothers and their children.

The aim of the study was to evaluate if 18F-FDG-PET has the potential to detect complete responders to PD1-therapy in patients with unresectable metastasized melanoma two weeks after therapy initiation. Between September 2014 and May 2016, ten patients (four females; 65 ± 12 y) received a whole-body 18F-FDG-PET/MRI examination at three time points: Before therapy start (t{sub 0}, base-line), two weeks (t{sub 1}, study examination) and three months after treatment initiation (t{sub 2}, reference standard). Therapy response was assessed with PET response criteria in solid tumors (PERCIST). Time to progression and overall survival (OS) were obtained for all patients. Three patients with partial metabolic response in PET at t{sub 1} turned out to have complete response at t{sub 2}. No tumor relapse was observed in those patients so far (observation period: 265, 511 and 728 days, respectively). At t{sub 2}, progressive metabolic disease (PMD) was seen in six patients from whom four showed PMD and two showed stable metabolic disease (SMD) at t{sub 1}. OS in patients with PMD at t{sub 2} varied between 148 and 814 days. SMD at both t{sub 1} and t{sub 2} was seen in one patient, tumor progress was observed after 308 days. Our study indicates that whole-body 18F-FDG-PET might be able to reliably identify complete responders to PD1-therapy as early as two weeks after therapy initiation in stage IV melanoma patients. This might help to shorten therapy regimes and avoid unnecessary side effects in the future. (orig.)

Recovering valuable metals from recycled photovoltaic modules.

Recovering valuable metals such as Si, Ag, Cu, and Al has become a pressing issue as end-of-life photovoltaic modules need to be recycled in the near future to meet legislative requirements in most countries. Of major interest is the recovery and recycling of high-purity silicon (> 99.9%) for the production of wafers and semiconductors. The value of Si in crystalline-type photovoltaic modules is estimated to be -$95/kW at the 2012 metal price. At the current installed capacity of 30 GW/yr, the metal value in the PV modules represents valuable resources that should be recovered in the future. The recycling of end-of-life photovoltaic modules would supply > 88,000 and 207,000 tpa Si by 2040 and 2050, respectively. This represents more than 50% of the required Si for module fabrication. Experimental testwork on crystalline Si modules could recover a > 99.98%-grade Si product by HNO3/NaOH leaching to remove Al, Ag, and Ti and other metal ions from the doped Si. A further pyrometallurgical smelting at 1520 degrees C using CaO-CaF2-SiO2 slag mixture to scavenge the residual metals after acid leaching could finally produce > 99.998%-grade Si. A process based on HNO3/NaOH leaching and subsequent smelting is proposed for recycling Si from rejected or recycled photovoltaic modules. Implications: The photovoltaic industry is considering options of recycling PV modules to recover metals such as Si, Ag, Cu, Al, and others used in the manufacturing of the PV cells. This is to retain its "green" image and to comply with current legislations in several countries. An evaluation of potential resources made available from PV wastes and the technologies used for processing these materials is therefore of significant importance to the industry. Of interest are the costs of processing and the potential revenues gained from recycling, which should determine the viability of economic recycling of PV modules in the future.

Background: Most experts agree that physical training is the cornerstone of cardiac rehabilitation. It might be even more beneficial than appropriate control of coronary risk factors. Objective: To determine the impact of energy caloric expenditure caused by daily physical activity on fitness and health condition of patients recovering from myocardial infarction. Methods: A comparative study with 147 patients recovered from acute, low-risk myocardial infarction, which were grouped into three groups.Patients were all males, less than 61 years old (mean 54 ± 6.0 who had received medical attention at the University Hospital "Dr. Gustavo Aldereguía Lima’’ of Cienfuegos. Cardiac rehabilitation had not been carried out. Results: Individuals who typically engage in regular physical activity with energy expenditure over 150 calories a day showed, in their ergometer test, to be in better shape than those who spend less than 150 kilocalories a day. Nevertheless, as calories expenditure exceeded 300 kcal / day physical shape was much better but characteristic symptoms of cardiovascular risk increased. Conclusions: Simply by carrying out common ordinary activities such as walking, with energy caloric expenditure from 150 to 300 calories a day, may be beneficial for low-risk, post-infarct patients who did not receive cardiac rehabilitation. It also influences physical shape and decreases the probabilities of adverse effects emergence.

Fundamento: La mayoría de los expertos coinciden en afirmar que el entrenamiento físico constituye la piedra angular en la rehabilitación cardiovascular. Este puede ser más beneficioso que el control adecuado de los factores de riesgos coronarios. Objetivo: Determinar la repercusión del consumo energético calórico por concepto de actividad física cotidiana, sobre la forma

Upgraded RECOVER system - CASDAC system

Yamamoto, Yoichi; Koyama, Kinji

1992-03-01

The CASDAC (Containment And Surveillance Data Authenticated Communication) system has been developed by JAERI for nuclear safeguards and physical protection of nuclear material. This system was designed and constructed as an upgraded RECOVER system, design concept of which was based on the original RECOVER system and also the TRANSEAVER system. Both of them were developed several years ago as a remote monitoring system for continual verification of security and safeguards status of nuclear material. The system consists of two subsystems, one of them is a Grand Command Center (GCC) subsystem and the other is a facility subsystem. Communication between the two subsystems is controlled through the international telephone line network. Therefore all communication data are encrypted to prevent access by an unauthorized person who may intend to make a falsification, or tapping. The facility subsystem has an appropriate measure that ensure data security and reliable operation under unattended mode of operator. The software of this system is designed so as to be easily used in other different types of computers. This report describes the outline of the CASDAC system and the results of its performance test. This work has been carried out in the framework of Japan Support Programme for Agency Safeguards (JASPAS) as a project, JA-1. (author)

The response to neoadjuvant chemotherapy has been proven to predict long-term clinical benefits for patients. Our research is to construct a nomogram to predict pathological complete response of human epidermal growth factor receptor 2 negative breast cancer patients. We enrolled 815 patients who received neoadjuvant chemotherapy from 2003 to 2015 and divided them into a training set and a validation set. Univariate logistic regression was performed to screen for predictors and construct the nomogram; multivariate logistic regression was performed to identify independent predictors. After performing the univariate logistic regression analysis in the training set, tumor size, hormone receptor status, regimens of neoadjuvant chemotherapy and cycles of neoadjuvant chemotherapy were the final predictors for the construction of the nomogram. The multivariate logistic regression analysis demonstrated that T4 status, hormone receptor status and receiving regimen of paclitaxel and carboplatin were independent predictors of pathological complete response. The area under the receiver operating characteristic curve of the training set and the validation set was 0.779 and 0.701, respectively. We constructed and validated a nomogram to predict pathological complete response in human epidermal growth factor receptor 2 negative breast cancer patients. We also identified tumor size, hormone receptor status and paclitaxel and carboplatin regimen as independent predictors of pathological complete response.

Full Text Available Abstract Objective The intent of this study was to examine the recovery of individuals who had been hospitalized for severe acute respiratory syndrome (SARS in the year following their discharge from the hospital. Parameters studied included serum levels of SARS coronavirus (SARS-CoV IgG antibody, tests of lung function, and imaging data to evaluate changes in lung fibrosis. In addition, we explored the incidence of femoral head necrosis in some of the individuals recovering from SARS. Methods The subjects of this study were 383 clinically diagnosed SARS patients in Beijing, China. They were tested regularly for serum levels of SARS-CoV IgG antibody and lung function and were given chest X-rays and/or high resolution computerized tomography (HRCT examinations at the Chinese PLA General Hospital during the 12 months that followed their release from the hospital. Those individuals who were found to have lung diffusion abnormities (transfer coefficient for carbon monoxide [DLCO] Findings Of all the subjects, 81.2% (311 of 383 patients tested positive for serum SARS-CoV IgG. Of those testing positive, 27.3% (85 of 311 patients were suffering from lung diffusion abnormities (DLCO Interpretation The lack of sero-positive SARS-CoV in some individuals suggests that there may have been some misdiagnosed cases among the subjects included in this study. Of those testing positive, the serum levels of SARS-CoV IgG antibody decreased significantly during the 12 months after hospital discharge. Additionally, we found that the individuals who had lung fibrosis showed some spontaneous recovery. Finally, some of the subjects developed femoral head necrosis.

A Socio-Technical Approach to Preventing, Mitigating, and Recovering from Ransomware Attacks.

Science.gov (United States)

Sittig, Dean F; Singh, Hardeep

2016-01-01

Recently there have been several high-profile ransomware attacks involving hospitals around the world. Ransomware is intended to damage or disable a user's computer unless the user makes a payment. Once the attack has been launched, users have three options: 1) try to restore their data from backup; 2) pay the ransom; or 3) lose their data. In this manuscript, we discuss a socio-technical approach to address ransomware and outline four overarching steps that organizations can undertake to secure an electronic health record (EHR) system and the underlying computing infrastructure. First, health IT professionals need to ensure adequate system protection by correctly installing and configuring computers and networks that connect them. Next, the health care organizations need to ensure more reliable system defense by implementing user-focused strategies, including simulation and training on correct and complete use of computers and network applications. Concomitantly, the organization needs to monitor computer and application use continuously in an effort to detect suspicious activities and identify and address security problems before they cause harm. Finally, organizations need to respond adequately to and recover quickly from ransomware attacks and take actions to prevent them in future. We also elaborate on recommendations from other authoritative sources, including the National Institute of Standards and Technology (NIST). Similar to approaches to address other complex socio-technical health IT challenges, the responsibility of preventing, mitigating, and recovering from these attacks is shared between health IT professionals and end-users.

Methods for recovering precious metals from industrial waste

Canda, L.; Heput, T.; Ardelean, E.

2016-02-01

The accelerated rate of industrialization increases the demand for precious metals, while high quality natural resources are diminished quantitatively, with significant operating costs. Precious metals recovery can be successfully made from waste, considered to be secondary sources of raw material. In recent years, concerns and interest of researchers for more increasing efficient methods to recover these metals, taking into account the more severe environmental protection legislation. Precious metals are used in a wide range of applications, both in electronic and communications equipment, spacecraft and jet aircraft engines and for mobile phones or catalytic converters. The most commonly recovered precious metals are: gold from jewellery and electronics, silver from X- ray films and photographic emulsions, industrial applications (catalysts, batteries, glass/mirrors), jewellery; platinum group metals from catalytic converters, catalysts for the refining of crude oil, industrial catalysts, nitric acid manufacturing plant, the carbon-based catalyst, e-waste. An important aspect is the economic viability of recycling processes related to complex waste flows. Hydrometallurgical and pyrometallurgical routes are the most important ways of processing electrical and electronic equipment waste. The necessity of recovering precious metals has opened new opportunities for future research.

A process for recovering valuable liquid hydrocarbons from coking coal, mineral coal, or oil shale through treatment with hydrogen under pressure at elevated temperature is described. Catalysts and grinding oil may be used in the process if necessary. The process provides for deashing the coal prior to hydrogenation and for preventing the coking and swelling of the deashed material. During the treatment with hydrogen, the coal is either mixed with coal low in bituminous material, such as lean coal or active coal, as a diluent or the bituminous constituents which cause the coking and swelling are removed by extraction with solvents.

G. Pfurtscheller

2009-01-01

Full Text Available EEG-based discrimination between different motor imagery states has been subject of a number of studies in healthy subjects. We investigated the EEG of 15 patients with complete spinal cord injury during imagined right hand, left hand, and feet movements. In detail we studied pair-wise discrimination functions between the 3 types of motor imagery. The following classification accuracies (mean ± SD were obtained: left versus right hand 65.03% ± 8.52, left hand versus feet 68.19% ± 11.08, and right hand versus feet 65.05% ± 9.25. In 5 out of 8 paralegic patients, the discrimination accuracy was greater than 70% but in only 1 out of 7 tetraplagic patients. The present findings provide evidence that in the majority of paraplegic patients an EEG-based BCI could achieve satisfied results. In tetraplegic patients, however, it is expected that extensive training-sessions are necessary to achieve a good BCI performance at least in some subjects.

2015-01-01

Full Text Available Traffic speed data plays a key role in Intelligent Transportation Systems (ITS; however, missing traffic data would affect the performance of ITS as well as Advanced Traveler Information Systems (ATIS. In this paper, we handle this issue by a novel tensor-based imputation approach. Specifically, tensor pattern is adopted for modeling traffic speed data and then High accurate Low Rank Tensor Completion (HaLRTC, an efficient tensor completion method, is employed to estimate the missing traffic speed data. This proposed method is able to recover missing entries from given entries, which may be noisy, considering severe fluctuation of traffic speed data compared with traffic volume. The proposed method is evaluated on Performance Measurement System (PeMS database, and the experimental results show the superiority of the proposed approach over state-of-the-art baseline approaches.

Recovering low-turbidity cutting liquid from silicon slurry waste.

Tsai, Tzu-Hsuan; Shih, Yu-Pei

2014-04-30

In order to recover a low-turbidity polyalkylene glycol (PAG) liquid from silicon slurry waste by sedimentation, temperatures were adjusted, and acetone, ethanol or water was used as a diluent. The experimental results show that the particles in the waste would aggregate and settle readily by using water as a diluent. This is because particle surfaces had lower surface potential value and weaker steric stabilization in PAG-water than in PAG-ethanol or PAG-acetone solutions. Therefore, water is the suggested diluent for recovering a low-turbidity PAG (sedimentation. After 50 wt.% water-assisted sedimentation for 21 days, the solid content of the upper liquid reduced to 0.122 g/L, and the turbidity decreased to 44 NTU. The obtained upper liquid was then vacuum-distillated to remove water. The final recovered PAG with 0.37 NTU had similar viscosity and density to the unused PAG and could be reused in the cutting process. Copyright © 2014 Elsevier B.V. All rights reserved.

In this research, the waste tail gas emitted from petrochemical processes, e.g. catalytic reforming unit, catalytic cracking unit and residue desulfurization unit, was recovered and reused as a replacement of natural gas (NG). On-site experimental results show that both the flame length and orange-yellowish brightness decrease with more proportion of waste gas fuel added to the natural gas, and that the adiabatic temperature of the mixed fuel is greater than 1800 C. A complete replacement of natural gas by the recovered waste gas fuel will save 5.8 x 10{sup 6} m{sup 3} of natural gas consumption, and 3.5 x 10{sup 4} tons of CO{sub 2} emission annually. In addition, the reduction of residual O{sub 2} concentration in flue gases from 4% to 3% will save 1.1 x 10{sup 6} m{sup 3} of natural gas consumption, reduce 43.0% of NO{sub x} emission, and 1.3 x 10{sup 3} tons of CO{sub 2} emission annually. Thus, from the viewpoint of the overall economics and sustainable energy policy, recovering the waste tail gas energy as an independent fuel source to replace natural gas is of great importance for saving energy, reducing CO{sub 2} emission reduction, and lowering environmental impact.

Sectional mandibular complete denture for a total maxillectomy patient with trismus: a clinical report.

Science.gov (United States)

Celakil, Tamer; Demir, Azize; Keskin, Haluk

2017-01-01

This report presents the case of a 60-year-old male patient with trismus induced by radiotherapy and fabrication of a sectional mandibular complete denture to allow the insertion of the denture into the mouth. A mandibular sectional denture was designed in two pieces with a locking mechanism by using mini anchor and ball abutment housing with cap. Patients who have undergone maxillectomy often have constricted mouth openings, as a result of surgical intervention and radiotherapy, and complain of an inability to insert or remove dentures. A new approach is vital for sectional dentures because existing sectional denture fabrication techniques cannot meet the ongoing needs of trismus patients. The mini anchor system with ball abutment housing has better mechanical retention in acrylic resin and can provide favorable stabilization during masticatory function; thus, additional framework is not required for assisting in stabilization and retention.

Completion of prescribed neoadjuvant chemotherapy for breast cancer is paramount to patients obtaining full benefit from the treatment; however, factors affecting neoadjuvant chemotherapy completion are not known. We hypothesized that race is a predictor of completion of neoadjuvant chemotherapy in patients with breast cancer. All patients with breast cancer treated with neoadjuvant chemotherapy 2009-2016 at a single institution were stratified by completion of neoadjuvant chemotherapy and by race. Univariate analysis and multivariable logistic regression were used to identify patient and tumor characteristics that affected the rate of neoadjuvant chemotherapy completion. A total of 92 (74%) of 124 patients completed their prescribed neoadjuvant chemotherapy. On univariate analysis, white patients were more likely to complete neoadjuvant chemotherapy than non-white patients (76% vs 50%, P = .006). Non-white patients were more likely to have government insurance and larger prechemotherapy tumors (both, P < .05), but these factors were not associated with rates of neoadjuvant chemotherapy completion. After controlling for age, insurance status, tumor size, and estrogen receptor status, whites remained associated with completion of neoadjuvant chemotherapy (OR 3.65, P = .014). At our institution, white patients with breast cancer were more likely than non-white patients to complete neoadjuvant chemotherapy. Further investigation into the underlying factors impacting this disparity is needed. Copyright © 2018 Elsevier Inc. All rights reserved.

Early Relapse of Unresectable Gallbladder Cancer after Discontinuation of Gemcitabine Monotherapy Administered for 5 Years in a Patient Who Had Complete Response to the Treatment

Full Text Available The tumor shrinkage effect of gemcitabine is considered to be limited in cases of advanced gallbladder cancer, and there are few reports of complete response to gemcitabine therapy in patients with this cancer. Therefore, the treatment continuation strategy in these patients, after a complete response has been achieved, still remains to be established. Here, we present the case of a 77-year-old patient with unresectable gallbladder cancer, who after showing complete response to gemcitabine monotherapy administered for 5 years, showed early relapse within only 11 months of discontinuation of the drug. Thus, it is necessary to establish a suitable treatment continuation strategy for patients who show complete response to gemcitabine treatment.

Radiolabeled metaiodobenzylguanidine is an analogue of norepinephrine used to localize tumors that express the neurohormone transporters, specifically those derived from the neural crest having a neuroendocrine origin. It is also used to treat non-surgical metastases derived from them. A review of the literature revealed symptomatic improvements associated to a decrease in hormone levels in a significant percentage of patients after (131)I-MIBG treatment. However, complete tumor remission has been described only in very few cases and hardly ever when bone metastases exist. We present a case of a patient diagnosed of malignant pheochromocytoma who achieved complete hormonal and metabolic response after (131)I-MIBG treatment (600 mCi) in spite of the presence of bone metastases.

The work of recovering helpers who work in the addiction rehabilitation centres was studied. The aim was to investigate the process of addicts becoming recovering helpers, and to study what peer help means to them. According to interpretative phenomenological analysis (IPA) design, subjects were selected, data were collected and analysed. 6 (5 males, 1 female), working as recovering helpers at least one year at addiction rehabilitation centres. Semi-structured life interviews were carried out and analysed according to IPA. Emerging themes from the interviews were identified and summarized, then interpreted as central themes: important periods and turning points of the life story interviews: the experience of psychoactive drugs use, the development of the addiction (which became " Turning Point No 1") then the "rock bottom" experience ("Turning Point No 2"). Then the experience of the helping process was examined: here four major themes were identified: the development of the recovering self and the helping self, the wounded helper and the skilled helper, the experience of the helping process. IPA was found to be a useful method for idiographic exploration of the development and the work of the recovering helpers. The work of the recovering helpers can be described as mentoring of the addict clients. Our experiences might be used for the training programs for recovering helpers as well as to adopt their professional role in addiction services.

Complete esophageal obstruction after (chemo)radiation for head and neck cancers is rare. However, inability to swallow one's own saliva strongly inflicts upon quality of life. Techniques for endoscopic recanalization in complete obstruction are not well established. We assessed the efficacy and safety of rendezvous recanalization. We performed a retrospective review of all patients who underwent endoscopic recanalization of complete proximal esophageal obstruction after radiotherapy between January 2009 and June 2016. Technical success was defined as an ability to pass an endoscope across the recanalized lumen, clinical success by changes in the dysphagia score. Adverse events were recorded prospectively. 19 patients with complete obstruction (dysphagia IV°), all of whom had failed at least one trial of conventional dilatation, underwent recanalization by endoscopic rendezvous, a combined approach through a gastrostomy and perorally under fluoroscopic control. Conscious sedation was used in all patients. In 18/19 patients (94.7%), recanalization was technically successful. In 14/18 patients (77.8%), the post-intervention dysphagia score changed to ≤ II. Three patients had their PEG removed. Factors negatively associated with success were obstruction length of 50 mm; and tumor recurrence for long-term success. No severe complications were recorded. Rendezvous recanalization for complete esophageal obstruction is a reliable and safe method to re-establish luminal patency. Differences between technical and clinical success rates highlight the importance of additional functional factors associated with dysphagia. Given the lack of therapeutic alternatives, rendezvous recanalization is a valid option to improve dysphagia.

Routine outcome measures are increasingly being mandated across mental health services in Australia and overseas. This requirement includes forensic mental health services, but their utility in such specialist services and the inter-relationships between the measures remain unclear. This study sought to characterise the risks, needs and stages of recovery of an entire cohort of forensic patients in one jurisdiction in Australia. Local expert groups, comprising of members of the forensic patient treating teams, were formed to gather information about the status and needs of all forensic patients in the State of New South Wales, Australia. The expert groups provided demographic information and completed three assessment tools concerning the risks, needs and stages of recovery of each forensic patient. The cohort of 327 forensic patients in NSW appears to be typical of forensic mental health service populations internationally when considering factors such as gender, diagnosis, and index offence. A number of important differences across the three structured tools for forensic patients in different levels of secure service provision are presented. The DUNDRUM Quartet demonstrated interesting findings, particularly in terms of the therapeutic security needs, the treatment completion, and the stages of recovery for the forensic patients in the community. The CANFOR highlighted the level of needs across the forensic patient population, whilst the HCR-20 data showed there was no significant difference in the mean clinical and risk management scores between male forensic patients across levels of security. To the authors' knowledge this is the first study of its kind in New South Wales, Australia. We have demonstrated the utility of using a suite of measures to evaluate the risks, needs, and stages of recovery for an entire cohort of forensic patients. The data set helps inform service planning and development, together with providing various avenues for future research.

2012-01-01

We report a case of complete atrioventricular (AV) block in a 40-year-old patient with Duchenne muscular dystrophy (DMD). While he was bed-ridden and required mechanical ventilation, his cardiac involvement was mild. He had the deletion of exon 45-52 in the dystrophin gene. He underwent transient complete AV block and came to require pacemaker implantation due to recurrence of complete AV block ten days after the first attack. Electrophysiological study revealed mild prolonged AH and HV interval. Although DMD patients with AV block have been rarely reported so far, attention should be paid to AV block for patients who prolonged their lives.

Dropout rates for effective therapies for posttraumatic stress disorder (PTSD) can be high, especially in practice settings. Although clinicians have intuitions regarding what treatment patients may complete, there are few systematic data to drive those judgments. A multivariable model of dropout risk was constructed with randomized clinical trial data (n = 160) comparing prolonged exposure (PE) and cognitive processing therapy (CPT) for rape-induced PTSD. A two-step bootstrapped variable selection algorithm was applied to identify moderators of dropout as a function of treatment condition. Employing identified moderators in a model, fivefold cross-validation yielded estimates of dropout probability for each patient in each condition. Dropout rates between patients who did and did not receive their model-indicated treatment were compared. Despite equivalent dropout rates across treatments, patients assigned to their model-indicated treatment were significantly less likely to drop out relative to patients who did not (relative risk = 0.49 [95% CI: 0.29-0.82]). Moderators included in the model were: childhood physical abuse, current relationship conflict, anger, and being a racial minority, all of which were associated with higher likelihood of dropout in PE than CPT. Individual differences among patients affect the likelihood they will complete a particular treatment, and clinicians can consider these moderators in treatment planning. In the future, treatment selection models could be used to increase the percentage of patients who will receive a full course of treatment, but replication and extension of such models, and consideration of how best to integrate them into routine practice, are needed. © 2018 Wiley Periodicals, Inc.

Treatment with Ipilimumab: A Case Report of Complete Response in a Metastatic Malignant Melanoma Patient

Directory of Open Access Journals (Sweden)

Alfredo Addeo

2013-05-01

Full Text Available Introduction: Over the past year, 3 agents have been approved for the treatment of melanoma by the Food and Drug Administration. These include pegylated interferon α-2b for stage III melanoma, vemurafenib for unresectable or metastatic melanoma with BRAF V600E mutation, and ipilimumab for unresectable or metastatic melanoma. Case Presentation: We present here the case of a 65-year-old Caucasian male diagnosed with advanced melanoma in April 2011 and treated with ipilimumab (Yervoy®, a monoclonal antibody targeting cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4, as second-line treatment after progression with dacarbazine, for (wild-type BRAF metastatic melanoma. The patient was referred to us for several painful lumps on his right arm. A biopsy of one of them revealed melanoma. CT and PET scans did not show any other lesions or a primary site. The patient was started on first-line chemotherapy with dacarbazine 850 mg/m2 on day 1, every 3 weeks. After 3 cycles, the patient showed disease progression with an increase in size of the skin metastasis. Second-line treatment was started with ipilimumab 3 mg/kg on day 1, every 3 weeks. At the end of the treatment, after 4 cycles, we documented a complete clinical response with total resolution of the skin metastasis. At the time of writing this paper, our patient had finished his treatment more than 9 months earlier and is still in complete remission. Conclusion: This is a paradigmatic case where, despite extensive metastatic disease, treatment with ipilimumab has confirmed its efficacy. It is still an open question why only a minority of patients have such a remarkable response, and further trials are warranted to address this important question.

A study is made of the alterations in anorectal physiology among rectal prolapse patients, evaluating the differences between fecal continent and incontinent individuals. Eighteen patients with complete rectal prolapse were divided into two groups: Group A (8 continent individuals) and Group B (10 incontinent women), while 22 healthy women were used as controls (Group C). Clinical exploration and perineal level measurements were performed, along with anorectal manometry, electrophysiology, and anorectal sensitivity to electrical stimuli. The main antecedents of the continent subjects were excess straining efforts, while the incontinent women presented excess straining and complex deliveries. Pathological perineal descent was a frequent finding in both groups, with a hypotonic anal canal at rest (p rest than the continent women (p rest, regardless of whether they are continent to feces or not. Continent patients have less pudendal neuropathy and therefore less pressure alterations at voluntary sphincter squeeze than incontinent individuals.

Renal amyloidosis is one of the most severe complications of familial Mediterranean fever (FMF). Colchicine has reduced the incidence of this complication, which now only appears in untreated, under-treated and resistant patients, but it is usually ineffective in patients with advanced amyloidosis. Here we report a patient with FMF and biopsy-proven amyloidosis who presented with nephrotic syndrome despite colchicine treatment. Anakinra (an interleukin-1β inhibitor) was started and a dramatic complete remission of nephrotic syndrome was observed in the following months. Anakinra can be an effective treatment for FMF patients with severe secondary amyloidosis. Copyright © 2015 Sociedad Española de Nefrología. Published by Elsevier España, S.L.U. All rights reserved.

Reversible complete atrioventricular block in patient with Wegener's granulomatosis - a report on a positive outcome with long term follow-up. Atrioventricular (AV) block is a rare complication of Wegener's granulomatosis (WG), thus there are no standards of management in such cases. We present a case of a patient with a dual-chamber pacemaker (DDD) implanted due to complete AV block in the course of Wegener's granulomatosis (WG). An immunosuppressive therapy resulted in the resolution of non-cardiac and AV conduction disorders. The diagnostic functions of the pacemaker enabled us to evaluate AV conduction over a five-year follow-up period. The resolution of AV conduction disorders, which accompanied WG remission, suggests that careful monitoring with temporary cardiac pacing may be considered in some patients before permanent pacemaker implantation.

A complete set of multidimensional Bell inequalities

We give a multidimensional generalization of the complete set of Bell-correlation inequalities given by Werner and Wolf (2001 Phys. Rev. A 64 032112) and by Zukowski and Brukner (2002 Phys. Rev. Lett. 88 210401), for the two-dimensional case. Our construction applies to the n-party, two-observable case, where each observable is d-valued. The d d n inequalities obtained involve homogeneous polynomials. They define the facets of a polytope in a complex vector space of dimension d n . We detail the inequalities obtained in the case d = 3 and, from them, we recover known inequalities. We finally explain how the violations of our inequalities by quantum mechanics can be computed and could be observed, when using unitary observables. (paper)

Highlights: • SiC was recovered from photovoltaic industry waste. • The recovered SiC is mainly consist of 3C-SiC, 6H-SiC and some silicon oxycarbides. • The recovered SiC shows photocatalytic H{sub 2} evolution from water. - Abstract: In recent years, the focus on creating a dependable and efficient means to recycle or recover the valuable parts from the waste material has drawn significantly attention as an environmentally friendly way to deal with the industrial wastes. The silicon carbide (SiC) crystalline is one of reusable material in the slurry wastes generated during wafer slicing. Here we report the use of recovered SiC from the slurry wastes as photocatalysts to produce hydrogen in the presence of Na{sub 2}SO{sub 3}-Na{sub 2}S as electron donor. The recovered SiC were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy spectra (XPS), UV–vis (UV–vis) spectroscopy, and photoluminescence (PL) spectroscopy. The morphology of SiC loaded with 1 wt% Pt as cocatalyst by thermal-reduction method was observed by scanning electron microscopy (SEM) and high resolution transmission electron microscopy (TEM). The experimental results reveal that the recovered SiC is mainly consist of 3C-SiC, 6H-SiC and some silicon oxycarbides on the surface of the SiC. The highest hydrogen production rate is 191.8 μmol h{sup −1} g{sup −1}. This study provides a way to recycle crystalline SiC from the discharged waste in the photovoltaic industry and reuse it as photocatalyst to yield hydrogen with the advantage of low energy consumption, low pollution and easy operation.

Progress into developing a pyrochemical technique for separating and recovering plutonium from spent americium extraction waste salts has concentrated on selective chemical reduction with lanthanum metal and calcium metal and on the solvent extraction of americium with calcium metal. Both techniques are effective for recovering plutonium from the waste salt, although neither appears suitable as a separation technique for recycling a plutonium stream back to mainline purification processes. 17 refs., 13 figs., 2 tabs

Ethical dilemma of recovering organs before donor death.

Science.gov (United States)

Khalid, Umair; Khalil, Sarwat

2011-08-01

Organ transplant has had a momentous effect in improving global health over the years. However, there exists a sizeable discrepancy between the supply and demand of organs, especially in developing countries, where lack of expertise, financial constraints, and inadequate transplant facilities have been obstacles. According to current practice, donors must be dead before unpaired vital organs can be recovered. Equal health warrants needs-based health care for everyone. Recovering viable organs from donors while they are alive, but with death inevitable, may be significant to persons on waiting lists. Future policies in organ transplantation must be made after thorough consideration of all aspects of donation and dealing with the inequalities of health care. These pose a challenge for medicolegal and ethical organizations.

Diabetes is a disease with high social burdens and is expected to increase gradually. A long-term management is essential for the treatment of diabetes, requiring patient self-cares. Diabetes education is important for such self-cares, but it does not sufficiently take place. In addition, little studies have been conducted on the barriers to the completion of diabetes education. This study, thus, aimed to analyze the factors related to the completion of diabetes education and investigate its barriers. Of 50,405 respondents to the fourth and fifth Korea National Health and Nutrition Examination Survey, a total of 3,820 were selected for the analysis, excluding those aged 29 or younger and those with missing values. The completion of diabetes education was set as a dependent variable and an analysis was made on the factors that affect the dependent variable. A multivariable logistic regression was employed for the analysis. Lower educational level was associated with less diabetes education, and the degree of diabetes education was lower in the group with male, the group that didn't have a family history or was not aware of a family history, the group that was not currently aware of diabetes and the group without a spouse. There was no difference in the completion of diabetes education by underlying diseases, family income level, age, residing area, economic activity status, insurance coverage, smoking, and drinking. Diabetes education is of importance for the treatment and management of diabetes. Currently, however, diabetes education is not sufficiently carried out in Korea. The completion rate of diabetes education was low in male, patients without or not knowing a family history, patients who were not currently aware of their diabetes, patients without a spouse, and patients with low educational level. Therefore, encouraging these patients to take the education will be a more effective approach to increase the completion rate of diabetes education.

Recover vigorous cells of Magnetospirillum magneticum AMB-1 by capillary magnetic separation

2010-07-01

Cultivable magnetotactic bacteria (MTB) in laboratory can provide sufficient samples for molecular microbiological and magnetic studies. However, a cold-stored MTB strain, such as Magnetospirillum magneticum AMB-1, often loses its ability to synthesize magnetosomes and consequently fails to sense the external magnetic field. It is therefore important to quickly recover vigorous bacteria cells that highly capable of magnetosome producing. In this study, a modified capillary magnetic separation system was designed to recover a deteriorating strain of Magnetospirillum magneticum AMB-1 that long-term cold-stored in a refrigerator. The results show that all cells obtained after a 3-cycle treatment were vigorous and had the ability to produce magnetosomes. Moreover, the 3rd-cycle recovered cells were able to form more magnetosome crystals. Compared with the colony formation method, this new method is time-saving, easily operated, and more efficient for recovering vigorous MTB cells.

Obtaining a diagnosis of tuberculosis (TB) is a prerequisite for accessing specific treatment, yet one third of estimated new cases are missed worldwide by National Programmes. This study investigated economic, geographical, socio-cultural and health system factors hindering adults' attendance and completion of the TB diagnostic process in Yemen, to inform interventions designed to improve patient access to services. The study employed a mixed methods design comprising a cross-sectional survey and In-Depth-Interviews (IDIs) and Focus Group Discussions (FGDs) among patients abandoning the diagnosis or registering for treatment. Adults with cough of ≥ 2 weeks attending a large governmental referral centre in Sana'a, Yemen, between 2009 and 2010, were eligible to participate. 497 and 446 (89.7%) participants were surveyed the first and second day of attending the services and 48 IDIs and 12 FGDs were also conducted. The majority of patients were disadvantaged and had poor literacy (61% illiterate), had travelled from rural areas (47%) and attended with companions (84%). Key barriers for attendance identified were clinic and transport costs (augmented by companions), distance from home, a preference for private services, strong social stigma and a lack of understanding of the diagnostic process. There were discrepancies between patient- and doctor-reported diagnosis and 46% of patients were unaware that TB treatment is free. Females faced more difficulties to attend than men. The laboratory practice of providing first-day negative smear results and making referrals to the private sector also discouraged patients from returning. Strategies to bring TB diagnostic services closer to communities and address the multiple barriers patients face to attend, will be important to increase access to TB diagnosis and care.

Gray matter (GM) and white matter (WM) volume loss occur in the brains of patients with acute anorexia nervosa (AN) and improve again upon weight restoration. Adolescence is an important time period for AN to begin. However, little is known about the differences between brain changes in adolescents vs adults. We used a meta-analysis and a qualitative review of all MRI studies regarding acute structural brain volume changes and their recovery in adolescents and adults with AN. 29 studies with 473 acute, 121 short-term weight-recovered and 255 long-term recovered patients with AN were included in the meta-analysis. In acute AN, GM and WM were reduced compared to healthy controls. Acute adolescent patients showed a significantly greater GM reduction than adults (-8.4 vs -3.1 %), the difference in WM (-4.0 vs -2.1 %) did not reach significance. Short-term weight-recovered patients showed a remaining GM deficit of 3.6 % and a non-significant WM reduction of 0.9 % with no age differences. Following 1.5-8 years of remission, GM and WM were no longer significantly reduced in adults (GM -0.4 %, WM -0.7 %); long-term studies for adolescents were scarce. The qualitative review showed that GM volume loss was correlated with cognitive deficits and three studies found GM regions, cerebellar deficits and WM to be predictive of outcome. GM and WM are strongly reduced in acute AN and even more pronounced in adolescence. Long-term recovery appears to be complete for adults while no conclusions can be drawn for adolescents, thus caution remains.

Purpose Breast implant–associated anaplastic large-cell lymphoma (BI-ALCL) is a rare type of T-cell lymphoma that arises around breast implants. The optimal management of this disease has not been established. The goal of this study is to evaluate the efficacy of different therapies used in patients with BI-ALCL to determine an optimal treatment approach. Patients and Methods In this study, we applied strict criteria to pathologic findings, assessed therapies used, and conducted a clinical follow-up of 87 patients with BI-ALCL, including 50 previously reported in the literature and 37 unreported. A Prentice, Williams, and Peterson model was used to assess the rate of events for each therapeutic intervention. Results The median and mean follow-up times were 45 and 30 months, respectively (range, 3 to 217 months). The median overall survival (OS) time after diagnosis of BI-ALCL was 13 years, and the OS rate was 93% and 89% at 3 and 5 years, respectively. Patients with lymphoma confined by the fibrous capsule surrounding the implant had better event-free survival (EFS) and OS than did patients with lymphoma that had spread beyond the capsule (P = .03). Patients who underwent a complete surgical excision that consisted of total capsulectomy with breast implant removal had better OS (P = .022) and EFS (P = .014) than did patients who received partial capsulectomy, systemic chemotherapy, or radiation therapy. Conclusion Surgical management with complete surgical excision is essential to achieve optimal EFS in patients with BI-ALCL. PMID:26628470

Encephalopathy is a disorder characterized by altered brain function, which can be attributed to various causes. Encephalopathy associated with metronidazole administration occurs rarely and depends on the cumulative metronidazole dose, and most patients with this condition recover rapidly after discontinuation of therapy. Because metronidazole is metabolized in the liver and can be transported by the cerebrospinal fluid and cross the blood-brain barrier, it may induce encephalopathy even at a low cumulative dose in patients with hepatic dysfunction. We experienced a patient who showed ataxic gait and dysarthric speech after receiving metronidazole for the treatment of hepatic encephalopathy that was not controlled by the administration of lactulose. The patient was diagnosed as metronidazole-induced encephalopathy, and stopping drug administration resulted in a complete recovery from encephalopathy. This case shows that caution should be exercised when administering metronidazole because even a low dose can induce encephalopathy in patients with liver cirrhosis.

Absence of MxA induction by interferon beta in patients with MS reflects complete loss of bioactivity

BACKGROUND: In patients with multiple sclerosis (MS), neutralizing antibodies (NAbs) appearing during treatment with interferon (IFN) beta reduce or in high concentrations abolish bioactivity and therapeutic efficacy. In vivo MxA induction by IFNbeta is used as a marker of biologic response....... Lack of MxA in vivo response in patients with multiple sclerosis with NAbs is a reliable marker of a completely blocked biologic response to IFNbeta, with no indication of residual bioactivity Udgivelsesdato: 2009/8/4...

A method of recovering metals from electronic waste comprises providing a powder comprising electronic waste in at least a first reactor and a second reactor and providing an electrolyte comprising at least ferric ions in an electrochemical cell in fluid communication with the first reactor and the second reactor. The method further includes contacting the powders within the first reactor and the second reactor with the electrolyte to dissolve at least one base metal from each reactor into the electrolyte and reduce at least some of the ferric ions to ferrous ions. The ferrous ions are oxidized at an anode of the electrochemical cell to regenerate the ferric ions. The powder within the second reactor comprises a higher weight percent of the at least one base metal than the powder in the first reactor. Additional methods of recovering metals from electronic waste are also described, as well as an apparatus of recovering metals from electronic waste.

Process for recovering uranium from wet process phosphoric acid

A process for recovering uranium from phosphoric acid solutions uses an acidified alkali metal carbonate solution for the second-stage strip of uranyl uranium from the ion-exchange solution. The stripped solution is then recycled to the ion-exchange circuit. In the first stripping stage the ion-exchange solution containing the recovered uranyl uranium and an inert organic diluent is stripped with ammonium carbonate, producing a slurry of ammonium uranyl tricarbonate. The second strip, with a solution of 50-200 grams per litre of sodium carbonate eliminates the problems of inadequate removal of phosphorus, iron and vanadium impurities, solids accumulation, and phase separation in the strip circuit

Lattice Boltzmann scheme for mixture modeling: analysis of the continuum diffusion regimes recovering Maxwell-Stefan model and incompressible Navier-Stokes equations.

Science.gov (United States)

Asinari, Pietro

2009-11-01

A finite difference lattice Boltzmann scheme for homogeneous mixture modeling, which recovers Maxwell-Stefan diffusion model in the continuum limit, without the restriction of the mixture-averaged diffusion approximation, was recently proposed [P. Asinari, Phys. Rev. E 77, 056706 (2008)]. The theoretical basis is the Bhatnagar-Gross-Krook-type kinetic model for gas mixtures [P. Andries, K. Aoki, and B. Perthame, J. Stat. Phys. 106, 993 (2002)]. In the present paper, the recovered macroscopic equations in the continuum limit are systematically investigated by varying the ratio between the characteristic diffusion speed and the characteristic barycentric speed. It comes out that the diffusion speed must be at least one order of magnitude (in terms of Knudsen number) smaller than the barycentric speed, in order to recover the Navier-Stokes equations for mixtures in the incompressible limit. Some further numerical tests are also reported. In particular, (1) the solvent and dilute test cases are considered, because they are limiting cases in which the Maxwell-Stefan model reduces automatically to Fickian cases. Moreover, (2) some tests based on the Stefan diffusion tube are reported for proving the complete capabilities of the proposed scheme in solving Maxwell-Stefan diffusion problems. The proposed scheme agrees well with the expected theoretical results.

2010-01-01

In 2008 statewide surveys of symptomatic foliage of nursery plants from Tennessee resulted in isolation of 43 isolates of Phytophthora spp. This sample set includes four described species (P. citrophthora, P. citricola, P. nicotianae, P. syringae), and a provisional species of Phytophthora ('P. hydropathica'). At the same time a stream-baiting survey was initiated to recover Phytophthora from eight watersheds in eastern Tennessee, some of which are near plant nurseries. Baiting was accomplished by submerging healthy Rhododendron leaves approximately 1 wk and isolation onto selective media. Six baiting periods were completed, and in total 98 Phytophthora isolates and 45 isolates of Pythium spp. were recovered. Three described species (P. citrophthora, P. citricola and P. irrigata) and the provisional species 'P. hydropathica' were obtained as well as three undescribed Phytophthora taxa and Pythium litorale. Isolates from both surveys were identified to species with morphology and the internal transcribed spacer (ITS) sequence. Isolates from species co-occurring in streams and nurseries (P. citricola, P. citrophthora and 'P. hydropathica') were characterized further with amplified fragment length polymorphism (AFLP) analyses and mefenoxam tolerance assays. Isolates representing a putative clonal genotype of P. citricola were obtained from both environmental and nursery sample sets.

However, research is lacking on whether an individual’s completion time (the amount of time that he/she takes to finish the screener has utility in predicting ADB, despite the fact that response speed has been useful in predicting behavior in other fields. The purpose of this study was to evaluate the degree to which SOAPP-R completion time is predictive of ADB.Materials and methods: This retrospective study analyzed completion-time data from 82 adult emergency department patients who completed the SOAPP-R on a tablet computer. The utility of SOAPP-R completion times in predicting ADB was assessed via logistic regression and the area under the curve (AUC statistic. An external measure of ADB using Prescription Drug Monitoring Program data defined ADB to have occurred in individuals with at least four opioid prescriptions and at least four prescribers in 12 months.Results: Although there was a slight trend for individuals with greater completion times to have greater odds of ADB (odds ratio 1

To explore the operation methods and clinical effects of transfer of the medial half of the coracoacromial ligament to reconstruct the coracoclavicular ligament in treating complete acromioclavicular joint dislocation. From January 2006 to June 2012,26 patients with acute complete acromioclavicular joint dislocation underwent surgery. Transfer of the medial half of the coracoacromial ligament to reconstruct the coracoclavicular ligament, additional clavical hoot plate and Kirschner wires fixation, were performed in all the patients. Among the patients, 18 patients were male and 8 patients were female, with an average age of 36.7 years old (ranged from 25 to 51 years). The duration from injury to operation was from 3 to 12 days with an average of 5 days. According to the Rockwood classification, 4 cases were grade III and 22 cases were grade V . Clinical manifestation included local swelling, tenderness with snapping, limitation of shoulder joint motion. In preoperative bilateral shoulder joint X-rays, the injured coracoclavicular distance was (16.2 ± 5.0) mm which was significantly wider than that of uninjured sides (7.6 ± 1.0) mm. Clinical results were evaluated according to X-rays and Constant-Murley score. All incisions obtained primary healing after operation without complication of infection, internal fixation breakage, redislocation. All the patients were followed up from 12 to 30 months with an average of 18 months. Kirschner wires and internal fixation plate were removed at 1 month and 8-10 months after operation, respectively. At final follow-up, the motion of shoulder joint recovered to normal and a no pain joint was obtained. According to Constant-Murley score, 24 cases got excellent results and 2 cases good. There was no significant difference after operation between the injured coracoclavicular distance and the uninjured contralateral side [(7.7 ± 1.2) mm vs (7.6 ± 1.0) mm), P > 0.05].

Rate shock crisis faces completed nukes

International Nuclear Information System (INIS)

Utroska, D.

1982-01-01

Political reluctance on the part of regulators to grant utilities a full rate base for large generating plants is a new crisis facing utilities with newly completed nuclear plants. Zero- or partial-rate treatment for large new plants will increase the financial strains of electric companies if they cannot recover their investment. Such rate decisions will affect the commitment to uncompleted and planned nuclear plants as the economic advantage is removed. Economists warn that consumer resistance to large rate increases to cover construction periods could lead to an overhaul of regulatory practices. Alternatives to sudden rate shocks could be moderated with phased-in increases or rate trending. Analysts disagree on whether consumer opposition is the beginning of a national movement or a regional response, but if other states follow Alabama's example of turning rate decisions over to the courts, it may confirm their assessment that the trending approach is unworkable

Objective Limitation of Medical Treatment (LMT) forms are an essential element of end-of-life care. Decision making around LMT is complex and often involves patients with dementia. Despite the complexity, junior doctors frequently play a central role in completing LMT forms. The present study sought perspectives from a range of stakeholders (hospital clinicians, medical education personnel, legal and advocacy staff) about junior doctors' roles in completing LMT forms in general and for patients with dementia. Methods Qualitative data were gathered in semi-structured interviews (SSI) and theoretical concepts were explored in roundtable discussion (RD). Participants were recruited through purposive and convenience sampling drawing on healthcare and legal personnel employed in the public hospital and aged care systems, selected from major metropolitan hospitals, healthcare and legal professional bodies and advocacy organisations in Victoria, Australia. The contents of the SSIs and RD were subject to thematic analysis using a framework approach. Data were indexed according to the topics established in the study aim; categories were systematically scrutinised, from which key themes were distilled. Results Stakeholders reported that completing LMT forms was difficult for junior doctors because of a lack of medical and legal knowledge, as well as clinical inexperience and inadequate training. Healthcare organisations (HCOs) either lacked policies about the role of junior doctors or had practices that were discordant with policy. In this process, there were substantial gaps pertaining to patients with dementia. Recommendations made by the study participants included the provision of supervised clinical exposure and additional training for junior doctors, strengthening HCO policies and explicit consideration of the needs of patients with dementia. Conclusions LMT forms should be designed for clarity and consistency across HCOs. Enhancing patient care requires appropriate

The purpose of this study was to explore the brain structural changes in type 2 diabetes and the effect of insulin on the brain using a surface-based cortical thickness analysis. High-resolution three-dimensional T1-weighted fast spoiled gradient recalled echo MRI were obtained from 11 patients with type 2 diabetes before and after insulin therapy. The cortical thickness over the entire brain was calculated, and cross-sectional and longitudinal surface-based cortical thickness analyses were also performed. Regional cortical thinning was demonstrated in the middle temporal gyrus, posterior cingulate gyrus, precuneus, right lateral occipital gyrus and entorhinal cortex bilaterally for patients with type 2 diabetes mellitus compared with normal controls. Cortical thickening was seen in the middle temporal gyrus, entorhinal cortex and left inferior temporal gyrus bilaterally after patients underwent 1 year of insulin therapy. These findings suggest that insulin therapy may have recovering effects on the brain cortex in type 2 diabetes mellitus. The precise mechanism should be investigated further.

PROCESS OF RECOVERING URANIUM FROM ITS ORES

Science.gov (United States)

Galvanek, P. Jr.

1959-02-24

A process is presented for recovering uranium from its ores. The crushed ore is mixed with 5 to 10% of sulfuric acid and added water to about 5 to 30% of the weight of the ore. This pugged material is cured for 2 to 3 hours at 100 to 110 deg C and then cooled. The cooled mass is nitrate-conditioned by mixing with a solution equivalent to 35 pounds of ammunium nitrate and 300 pounds of water per ton of ore. The resulting pulp containing 70% or more solids is treated by upflow percolation with a 5% solution of tributyl phosphate in kerosene at a rate equivalent to a residence time of about one hour to extract the solubilized uranium. The uranium is recovered from the pregnant organic liquid by counter-current washing with water. The organic extractant may be recycled. The uranium is removed from the water solution by treating with ammonia to precipitate ammonium diuranate. The filtrate from the last step may be recycled for the nitrate-conditioning treatment.

Plant species, including algae and fungi, are based on type specimens to which the name of a taxon is permanently attached. Applying a scientific name to any specimen therefore requires demonstrating correspondence between the type and that specimen. Traditionally, identifications are based on morpho-anatomical characters, but recently systematists are using DNA sequence data. These studies are flawed if the DNA is isolated from misidentified modern specimens. We propose a genome-based solution. Using 4 × 4 mm(2) of material from type specimens, we assembled 14 plastid and 15 mitochondrial genomes attributed to the red algae Pyropia perforata, Py. fucicola, and Py. kanakaensis. The chloroplast genomes were fairly conserved, but the mitochondrial genomes differed significantly among populations in content and length. Complete genomes are attainable from 19(th) and early 20(th) century type specimens; this validates the effort and cost of their curation as well as supports the practice of the type method.

Differences in zinc status and the leptin axis in anorexic and recovered adolescents and young adults: a pilot study

Directory of Open Access Journals (Sweden)

2012-03-01

Full Text Available Evidence from animal studies suggests that leptin metabolism is associated with zinc (Zn status. However, research investigating this relationship in adolescents and young adults with anorexia nervosa (AN is scarce; the present study aims to fill that gap.Serum concentrations of leptin, the soluble leptin receptor (sOB-R and the free leptin index (FLI were obtained in healthy control subjects (n=19, acutely ill individuals (n=14 and recovered patients with AN (n=15. Serum Zn concentrations noted in previous research data were also incorporated for all groups.Leptin, FLI and Zn concentrations were higher in recovered subjects with AN when compared with acutely ill AN patients. Remitted patients showed higher sOB-R concentrations but no difference in FLI compared with the control group. Leptin and FLI were lower in the acutely ill patients compared with the control subjects, who showed no differences in Zn concentrations. Zn concentrations were not correlated with leptin, sOB-R or FLI concentrations in any of the three investigated subgroups.The present investigation does not entirely support an association between Zn, Leptin and FLI concentrations in subjects with AN, possibly due to limited statistical power. Further research and replication of the present findings related to the interaction between leptin and Zn is warranted. However, with respect to serum leptin levels the data of the present investigation indicate that acutely ill and remitted patients with AN differ as regards serum leptin concentrations and FLI, which is in line with previous research.

We aimed to evaluate whether mean platelet volume (MPV) and platelet distribution width (PDW) are helpful to identify complete thrombus resolution (CTR) after acute deep venous thrombosis (DVT). Patients who had first-time episode of acute proximal DVT were included in this retrospective study. 100 patients with DVT were divided into two groups according to absence (group 1; n = 68) or presence (group 2; n = 32) of CTR on doppler ultrasonography at month 6. There were no significant difference in admission MPV and PDW levels between group 1 and group 2. MPV (p = 0.03) and PDW (p venous thrombosis in DVT patients. Receiver operating characteristics analysis revealed that a 8.4 % decrease in admission MPV at month 6 provided 62 % sensitivity and 62 % specificity (AUC: 0.64) and a 15.4 % decrease in admission PDW at month 6 provided 87 % sensitivity and 94 % specificity (AUC: 0.89) for prediction of CTR in DVT patients. Percent change in admission MPV and PDW levels at month 6 may be used to identify the patients with CTR after a first episode of acute proximal DVT.

A regular black hole model, which has been proposed by Hayward (2006) in , is reconsidered in the framework of higher dimensional TeV unification and self-complete quantum gravity scenario (Dvali and Gomez (2010) , Dvali, Folkerts and Germani (2010) , Spallucci and Ansoldi (2011) ). We point out the 'quantum' nature of these objects and compute their cross section production by taking into account the key role played by the existence of a minimal lengthl{sub 0}. We show that the threshold energy is related to l{sub 0}. We recover, in the high energy limit, the standard 'black-disk' form of the cross section, while it vanishes, below threshold, faster than any power of the invariant mass energy {radical}(-s).

This was a prospective, single-arm pilot study. Eligible participants included those scheduled for a laparotomy for presumed or known gynecologic malignancy. Patients completed a Web-based "STAR" (Symptom Tracking and Reporting for Patients) questionnaire once preoperatively and weekly during the 6-week postoperative period. The questionnaire consisted of the patient adaptation of the NCI CTCAE 3.0 and EORTC QLQ-C30 3.0. When a patient submitted a response that was concerning, an automated email alert was sent to the clinician. The patient's assessment of STAR's usefulness was measured via an exit survey. Forty-nine patients completed the study. The procedures included the following: hysterectomy±staging (67%), resection of tumor (22%), salpingo-oophorectomy (6%), and other (4%). Most patients (82%) completed at least 4 sessions in STAR. The CTC generated 43 alerts. These alerts resulted in 25 telephone contacts with patients, 2 ER referrals, one new appointment, and one pharmaceutical prescription. The 3 most common patient-reported symptoms generating an alert were as follows: poor performance status (19%), nausea (18%), and fatigue (17%). Most patients found STAR useful (80%) and would recommend it to others (85%). Application of a Web-based, electronic STAR system is feasible in the postoperative period, highly accepted by patients, and warrants further study. Poor performance status, nausea, and fatigue were the most common distressing patient-reported symptoms. Copyright © 2012 Elsevier Inc. All rights reserved.

Endoscopic subureteral injection of dextranomer/hyaluronic acid has become an established alternative to long-term antibiotic prophylaxis or surgical treatment for vesicoureteral reflux. We evaluated the effectiveness of endoscopic injection of dextranomer/hyaluronic acid in intermediate and high grade vesicoureteral reflux in patients with complete duplex collecting systems. A total of 123 children underwent endoscopic correction of intermediate or high grade vesicoureteral reflux using injection of dextranomer/hyaluronic acid into complete duplex systems between 2001 and 2010. Vesicoureteral reflux was diagnosed by voiding cystourethrogram, and dimercapto-succinic acid scan was performed to evaluate the presence of renal scarring. Followup ultrasound and voiding cystourethrogram were performed 3 months after the outpatient procedure and renal ultrasound thereafter every 2 years. Mean followup was 6.7 years. Complete duplex systems were unilateral in 110 patients and bilateral in 13. Reflux severity in the 136 refluxing units was grade II in 1 (0.7%), III in 52 (38.2%), IV in 61 (44.9%) and V in 22 (16.2%). Dimercapto-succinic acid scan revealed renal functional abnormalities in 63 children (51.2%). Vesicoureteral reflux resolved after the first endoscopic injection of dextranomer/hyaluronic acid in 93 ureters (68.4%), after a second injection in 35 (25.7%) and after a third injection in 8 (5.9%). Febrile urinary tract infection developed in 5 patients (4.1%) during followup. No patient required ureteral reimplantation or experienced significant complications. Our results confirm the safety and efficacy of endoscopic injection of dextranomer/hyaluronic acid in eradicating intermediate and high grade vesicoureteral reflux in patients with complete duplex systems. We recommend this minimally invasive, 15-minute outpatient procedure as a viable option for treating intermediate and high grade vesicoureteral reflux in patients with complete duplex collecting systems

To describe the completeness of routinely collected primary care data that could be used by computer models to predict clinical outcomes among patients with Type 2 Diabetes (T2D). Data on blood pressure, weight, total cholesterol, HDL-cholesterol and glycated haemoglobin levels for regular patients were electronically extracted from the medical record software of 12 primary care practices in Australia for the period 2000-2012. The data was analysed for temporal trends and for associations between patient characteristics and completeness. General practitioners were surveyed to identify barriers to recording data and strategies to improve its completeness. Over the study period data completeness improved up to around 80% complete although the recording of weight remained poorer at 55%. T2D patients with Ischaemic Heart Disease were more likely to have their blood pressure recorded (OR 1.6, p=0.02). Practitioners reported not experiencing any major barriers to using their computer medical record system but did agree with some suggested strategies to improve record completeness. The completeness of routinely collected data suitable for input into computerised predictive models is improving although other dimensions of data quality need to be addressed.

A process useful in recovering uranium from deposits on stainless steel liner surfaces of calutrons is presented. The deposit is removed from the stainless steel surface by washing with aqueous nitric acid. The solution obtained containing uranium, chromium, nickel, copper, and iron is treated with an excess of ammonium hydroxide to precipitnte the uranium, iron, and chromium and convert the nickel and copper to soluble ammonio complexions. The precipitated material is removed, dried and treated with carbon tetrachloride at an elevated temperature of about 500 to 600 deg C to form a vapor mixture of UCl/ sub 4/, UCl/sub 5/, FeCl/sub 3/, and CrCl/sub 4/. The UCl/sub 4/ is separated from this vapor mixture by selective fractional condensation at a temperature of about 500 to 400 deg C.

Leahey, T; Wilson, H

1920-11-13

To recover oil free from inorganic impurities and water, and utilize the oil vapor and tarry matter for the production of heat, shale is heated in a retort at a temperature of not less than 120/sup 0/C. The vapors pass by a pipe into a water jacketed condenser from which the condensate and gas pass through a pipe into a chamber and then by a pipe to a setting chamber from where the light oils are decanted through a pipe into a tank. The heavy oil is siphoned through a pipe into a tank, while the gas passes through a pipe into a scrubber and then into a drier, exhauster and pipe to the flue and ports, above the fire-bars, into the retort. Air is introduced through a pipe, flue, and ports.

The main treatment strategies for chronic pancreatitis in young patients include therapeutic endoscopic retrograde cholangio-pancreatography (ERCP) intervention and surgical intervention. Therapeutic ERCP intervention is performed much more extensively for its minimally invasive nature, but a part of patients are referred to surgery at last. Historical and follow-up data of 21 young patients with chronic pancreatitis undergoing duodenum-preserving total pancreatic head resection were analyzed to evaluate the outcomes of therapeutic ERCP intervention and surgical intervention in this study. The surgical complications of repeated therapeutic ERCP intervention and surgical intervention were 38% and 19% respectively. During the first therapeutic ERCP intervention to surgical intervention, 2 patients developed diabetes, 5 patients developed steatorrhea, and 5 patients developed pancreatic type B pain. During the follow-up of surgical intervention, 1 new case of diabetes occurred, 1 case of steatorrhea recovered, and 4 cases of pancreatic type B pain were completely relieved. In a part of young patients with chronic pancreatitis, surgical intervention was more effective than therapeutic ERCP intervention on delaying the progression of the disease and relieving the symptoms.

Randomized trials conducted in the 1980s have established the effectiveness of 5-fluorouracil-based adjuvant chemotherapy in treating stage-III colon cancer. However, the initiation of adjuvant chemotherapy is just the first step for survival improvement. Little is known about the actual completion rate of such a therapy in the community. The objectives of this study were to measure the initiation and completion rate of adjuvant chemotherapy and to identify the associated factors. We studied 12,265 patients aged 65+ diagnosed with stage-III colon cancer between 1991 and 2005 who were identified from the Surveillance, Epidemiology, and End Results-Medicare linked database. Chemotherapy initiation was defined as at least one claim indicating the use of chemotherapy. The first and last claims were used to measure the length of chemotherapy. A complete course of chemotherapy was defined as 8-13 months for 1991-1995 cohort and 5-7 months for 1996-2005 cohort according to clinical guideline. Of the 12,265 patients, 64.4% received adjuvant chemotherapy within 3 months after tumor resection. Among those who had chemotherapy initiated, 62.2% (or 38.0% of 12,265 patients) received a complete course of chemotherapy. Patient's age at diagnosis, marital status, and comorbidity score were the significant predictors for chemotherapy initiation. These variables remained significant in predicting chemotherapy completion after adjusting for year of diagnosis and other factors. In conclusion, initiation and completion of chemotherapy was largely influenced by patient's age, marital status and comorbidity. Further investigation is needed to explore the cause of these differences in adherence to standard treatment that is essential for better quality of cancer care.

This study compared the stone opacity effect in patients who had radiopaque and radiolucent stones in percutaneous nephrolithotomy (PCNL) results. The medical records of 171 complete supine PCNL procedures were gathered. Patients were categorized into two groups: those with radiopaque (n=141) and those with radiolucent (n=30) stones. Kidney, ureter and bladder x-ray was done a day after PCNL and Ultrasound imaging was done two weeks later to evaluate the stone free rate. A stone free result was defined as having less than 4 mm residual stone size. Outcome parameters were compared by univariate analysis and those which were significantly different between the two groups were assessed by multivariate binary logistic regression analysis. There were no significant differences in age, sex, body mass index, hypertension, diabetes mellitus, pre-surgery hemoglobin, pre-surgery serum creatinine, stone and also surgery-related parameters between the two groups. Stone free rate, surgery time, complication-related parameters, hemoglobin drop, serum creatinine and glomerular filtration rate (GFR) changes were similar in both groups based on univariate analysis. The radiopaque group had higher post-surgery GFR (p=0.04) and longer hospital stay (p=0.009). However, opacity had no effect on these outcomes after multivariate analysis. Higher post-surgery GFR was seen in patient with higher GFR before surgery (p<0.0001). Also, higher hemoglobin before surgery was correlated with less hospital stay (p=0.001). The complete supine percutaneous nephrolithotomy outcomes are similar in patients with radiopaque and radiolucent stones.

Full Text Available Tooth loss can cause loss of occlusal, masticatory, esthetic, physiognomic, phonetic and psychosocial function of patients. The most frequently used treatment method of completely edentulous patients and patients with a small number of remaining teeth are complete dentures or overdentures. One of the most important clinical and laboratory procedures in their fabrication is functional impression taking. The aim of this paper was to present procedures of taking functional impressions in fabrication of complete dentures and overdentures, using standardized techniques and materials. An accurate functional impression together with other correctly performed clinical and laboratory procedures ensure good retention and stability of dentures, which is a precondition for restoring patients’ lost functions.

To correlate emotional reactions to tooth loss with denture satisfaction attributes in elderly complete denture wearers. Total tooth loss is a serious life event, and poor oral health has an impact on daily life. Edentulism treated by rehabilitation with dentures can have a positive effect on patients' self-image and social behaviour. A group of 80 edentulous subjects undergoing routine prosthetic care in a Greek Department of Prosthetic Dentistry were interviewed using two structured questionnaires. The first questionnaire explored reactions to tooth loss, whereas the second measured their subjective experience of complete dentures. The responses to both questionnaires were compared using the statistical package SPSS v.17. The results showed significant correlation between aspects of tooth loss experience and complete denture satisfaction. Despite the fact that a substantial proportion of patients were satisfied with their complete dentures, some patients experienced increased social and psychological problems related to their edentulousness and the wearing of complete dentures. The aesthetic and functional aspects of complete dentures affected both patients' social behaviour and self-confidence. Total tooth loss was not only reflected in patient's social behaviour and self-image, but it had a complex and multifaceted impact on satisfaction from complete dentures. © 2011 The Gerodontology Society and John Wiley & Sons A/S.

Life experiences of patients who have completed tuberculosis treatment: a qualitative investigation in southeast Brazil

Science.gov (United States)

2013-01-01

Background Despite being curable, tuberculosis is still a stigmatized disease. Not only is TB patients’ suffering due to its clinical manifestations, but also because of society’s prejudice, embarrassing situations, and even self-discrimination. This study aims to investigate psychosocial experiences of patients who have completed tuberculosis treatment in São Carlos a municipality in the interior of São Paulo State, Brazil. Methods This study, of a clinical-qualitative nature, sought to understand the meanings provided by the participants themselves. Fifteen individuals, who had successfully completed tuberculosis treatment, participated in this research. The sample size was established using the information saturation criterion. Data were collected by means of interviews with in-depth open-ended questions. Data were treated by categorizing and analyzing content according to themes. Results Regardless of all progress, this study found that TB still causes patients to suffer from fear of transmission, social prejudice, and death. Despite the fact that the emotional support provided by families and healthcare professionals is considered essential to treatment adherence and completion, participants in this study reveal that friends and colleagues have distanced themselves from them for fear of contagion and/or prejudice. Ignorance about the disease and its transmission modes can be found in the interviewees’ statements, which seems to indicate that they have become vectors of transmission of stigma themselves. Patients’ medical leave from work during treatment may be due to both their health conditions and their attempt to avoid social/emotional embarrassment. There are accounts that TB has caused psychosocial damage to patients’ lives and that they feel more fatigue and lassitude and have begun to pay more attention to their own health. Conclusions Healthcare workers should be aware of the ways TB treatment affect patients’ psychosocial life and

Purpose/Objective: Previous studies of patients with surgically resected nonsmall cell lung cancer and chest wall invasion have shown conflicting results with respect to prognosis. Whether high risk subsets of the T3N0M0 population exist with respect to local, regional, and distant control as well as overall survival has been difficult to ascertain due to small numbers of patients in most reported series. Therefore, a review of patients with completely resected T3N0M0 nonsmall cell lung cancer was undertaken to analyze patient and tumor characteristics as well as surgical interventions that might influence patterns of failure and overall survival. Materials and Methods: A retrospective review was performed for all patients (91) with T3N0M0 nonsmall cell lung cancer who had undergone a complete resection between the years 1979 to 1993. The following potential prognostic factors were recorded from each patients history: tumor size, tumor location (bronchus vs. pleura vs. chestwall), tumor grade, histology, patient age, the use of adjuvant radiation therapy ((17(91)) patients received adjuvant therapy), and the type of surgical procedure performed (chestwall resection vs. extrapleural resection). The actuarial rates of freedom from local recurrence (FFLR), freedom from regional nodal recurrence (FFRR), freedom from distant recurrence (FFDR), and overall survival were calculated from the date of diagnosis by the method of Kaplan-Meier. Results: The following table illustrates two and five year outcomes: None of the patients, tumor, or treatment characteristics that were analyzed were associated with a significant influence on the four parameters outlined in the above table. Conclusion: Patients with completely resected T3N0M0 nonsmall cell lung cancer have a similar local control and overall survival irrespective of primary location, type of surgery performed, or use of adjuvant radiation therapy. Additionally, the tumor recurrence rate and overall survival found in

Coronary artery bypass grafting (CABG) with incomplete revascularization (ICR) is thought to decrease survival. We studied the survival of patients with ICR undergoing total arterial grafting. In a consecutive series of all-comer 1000 patients with isolated CABG, operative and midterm survival were assessed for patients undergoing complete versus ICR, with odds ratios and hazard ratios, adjusted for European System for Cardiac Operative Risk Evaluation category, CABG urgency, age, and comorbidities. In this series of 1000 patients with 98% arterial grafts (2922 arterial, 59 vein grafts), 73% of patients with multivessel disease received bilateral internal mammary artery grafts. ICR occurred in 140 patients (14%). Operative mortality was 3.8% overall, 8.6% for patients with ICR, and 3.2% for patients with complete revascularization (P = .008). For operative mortality using multivariable logistic regression, after controlling for European System for Cardiac Operative Risk Evaluation category (P System for Cardiac Operative Risk Evaluation category (P reserved.

2018-02-08

An ill-fitting complete denture has the potential to create pain and discomfort as well as conceal or confound the diagnosis of other primary sources of orofacial pain such as trigeminal neuralgia. Guidelines of the American Academy of Orofacial Pain offer an evidence-based approach for the assessment, diagnosis, and management of orofacial pain. A complete and accurate differential diagnosis is paramount to the success of treatment as well as to the circumvention of unnecessary therapy. The purpose of this clinical report was to emphasize an evidence-based approach to the diagnosis and treatment of orofacial pain in a patient with edentulism and a history of prolonged denture wear.

Kittai, Adam; Yu, Eun-Mi; Tabbara, Imad

2014-12-23

Granulocytic sarcoma, also known as myeloid sarcoma, is an extramedullary tumour composed of immature myeloid cells. Granulocytic sarcoma is typically found in patients with acute myeloid leukaemia, accelerated phase or blast crisis of chronic myeloid leukaemia, myelodysplastic syndrome, or as an isolated event without bone marrow involvement. We present a case of granulocytic sarcoma in a patient with chronic myeloid leukaemia in the setting of complete haematological, molecular and cytogenetic remission. Our patient was first treated with imatinib for chronic-phase chronic myeloid leukaemia. After maintaining remission for 42 months, he developed a granulocytic sarcoma in his spine. In this case report, we describe our case, along with the three other cases reported in the literature. In addition to being a rare diagnosis, this case demonstrates the importance of being vigilant in diagnosing the cause of back pain and atypical symptoms in patients with a history of leukaemia. 2014 BMJ Publishing Group Ltd.

Full Text Available Optimization of the AV-interval (AVI in DDD pacemakers improves cardiac hemodynamics and reduces pacemaker syndromes. Manual optimization is typically not performed in clinical routine. In the present study we analyze the prevalence of E/A wave fusion and A wave truncation under resting conditions in 160 patients with complete AV block (AVB under the pre-programmed AVI. We manually optimized sub-optimal AVI.We analyzed 160 pacemaker patients with complete AVB, both in sinus rhythm (AV-sense; n = 129 and under atrial pacing (AV-pace; n = 31. Using Doppler analyses of the transmitral inflow we classified the nominal AVI as: a normal, b too long (E/A wave fusion or c too short (A wave truncation. In patients with a sub-optimal AVI, we performed manual optimization according to the recommendations of the American Society of Echocardiography.All AVB patients with atrial pacing exhibited a normal transmitral inflow under the nominal AV-pace intervals (100%. In contrast, 25 AVB patients in sinus rhythm showed E/A wave fusion under the pre-programmed AV-sense intervals (19.4%; 95% confidence interval (CI: 12.6-26.2%. A wave truncations were not observed in any patient. All patients with a complete E/A wave fusion achieved a normal transmitral inflow after AV-sense interval reduction (mean optimized AVI: 79.4 ± 13.6 ms.Given the rate of 19.4% (CI 12.6-26.2% of patients with a too long nominal AV-sense interval, automatic algorithms may prove useful in improving cardiac hemodynamics, especially in the subgroup of atrially triggered pacemaker patients with AV node diseases.

2015-01-01

Patients with full adentia are characterized by the formation of specific psycho-emotional status. Rational psychotherapeutic support of these patients largely determines the efficiency of dental prosthetic treatment. At the same time, the definition of mental and emotional status is not included in the diagnostic examination protocol. Considering the above the purpose of the study was to evaluate mental and emotional status of patients receiving complete dentures. Prosthetic rehabilitation of 30 patients with complete teeth loss was performed and clinical evaluation and evaluation of mental and emotional status were carried out before and after treatment. Patients with negative experiences of prosthetics showed a higher level of personal and situational anxiety. There was correlation of adaptation to removable dentures and the patient's personality traits. It is determined that emotional instability during treatment tends to decrease affecting the timing of adaptation to complete dentures. It is noted that patients with repeated prosthetics have earlier recovery of coordination ability of the masticatory muscles.

The tannery industry faces growing environmental concerns because of the high hazardous metal content of its process waste. The formation, during the tanning process, of the highly toxic hexavalent chromium precludes the use of conventional thermal incineration processes. Borge Tannery in Norway, which processes 600 cattle hides per day, has solved the problem by using new PyroArc technology. The PyroArc waste processing plant can treat all of the tannery's production wastes, transforming them into useful products such as fuel gas and re-usable metal. The fuel gas consists mainly of carbon monoxide, hydrogen and nitrogen, and has a calorific value of about 4 MJ/Nm{sub 3}. About 65-70% of the energy content of the source material (waste or biomass) is recovered in the gas, and this is used to produce steam and/or electricity in a gas engine with a capacity of 580 kW. A further 20-25% of the initial energy content is recovered as heat or low-pressure steam. The plant is designed to be self-sufficient in energy (1.5 MW) and to meet the tannery's maximum requirements for hot water and steam. (UK)

Recovering method for high level radioactive material

International Nuclear Information System (INIS)

Fukui, Toshiki

1998-01-01

Offgas filters such as of nuclear fuel reprocessing facilities and waste control facilities are burnt, and the burnt ash is melted by heating, and then the molten ashes are brought into contact with a molten metal having a low boiling point to transfer the high level radioactive materials in the molten ash to the molten metal. Then, only the molten metal is evaporated and solidified by drying, and residual high level radioactive materials are recovered. According to this method, the high level radioactive materials in the molten ashes are transferred to the molten metal and separated by the difference of the distribution rate of the molten ash and the molten metal. Subsequently, the molten metal to which the high level radioactive materials are transferred is heated to a temperature higher than the boiling point so that only the molten metal is evaporated and dried to be removed, and residual high level radioactive materials are recovered easily. On the other hand, the molten ash from which the high level radioactive material is removed can be discarded as ordinary industrial wastes as they are. (T.M.)

Process for recovering xenon from radioactive gaseous wastes

International Nuclear Information System (INIS)

Kishimoto, Tsuneo.

1980-01-01

Purpose: To recover pure xenon economically and efficiently by amply removing radioactive krypton mixed in xenon without changing the rectifying capacity of an xenon rectifying system itself. Method: Xe containing radioactive Kr(Kr-85) is rectified to reduce the concentration of radioactive Kr. Thereafter, non-radioactive Kr or Ar is added to Xe and further the rectification is carried out. The raw material Xe from the Xe adsorption system of, for example, a radioactive gaseous waste disposal system is cooled to about 100 0 C by a heat-exchanger and thereafter supplied to a rectifying tower to carry out normal rectification of Xe thereby to reduce the concentration of Kr contained in Xe at the tower bottom to the rectification limit concentration. Then, non-radioactive Kr is supplied via a precooler to the tower bottom to continue the rectification, thus the Xe fractions at the tower bottom, in which the concentration of radioactive Kr is reduced, being compressed and recovered.

An alternative approach to recovering valuable metals from zinc phosphating sludge.

Science.gov (United States)

Kuo, Yi-Ming

2012-01-30

This study used a vitrification process (with good potential for commercialization) to recover valuable metals from Zn phosphating sludge. The involved vitrification process achieves two major goals: it transformed hazardous Zn phosphating sludge into inert slag and it concentrated Fe (83.5%) and Zn (92.8%) into ingot and fine particulate-phase material, respectively. The Fe content in the ingot was 278,000 mg/kg, making the ingot a potential raw material for iron making. The fine particulate-phase material (collected from flue gas) contained abundant Zn (544,000 mg/kg) in the form of ZnO. The content (67.7%) of ZnO was high, so it can be directly sold to refineries. The recovered coarse particulate-phase material, with insufficient amount of ZnO, can be recycled as a feeding material for Zn re-concentration. Therefore, the vitrification process can not only treat hazardous materials but also effectively recover valuable metals. Copyright © 2011 Elsevier B.V. All rights reserved.

One bacterial cell, one complete genome.

Full Text Available While the bulk of the finished microbial genomes sequenced to date are derived from cultured bacterial and archaeal representatives, the vast majority of microorganisms elude current culturing attempts, severely limiting the ability to recover complete or even partial genomes from these environmental species. Single cell genomics is a novel culture-independent approach, which enables access to the genetic material of an individual cell. No single cell genome has to our knowledge been closed and finished to date. Here we report the completed genome from an uncultured single cell of Candidatus Sulcia muelleri DMIN. Digital PCR on single symbiont cells isolated from the bacteriome of the green sharpshooter Draeculacephala minerva bacteriome allowed us to assess that this bacteria is polyploid with genome copies ranging from approximately 200-900 per cell, making it a most suitable target for single cell finishing efforts.

While the bulk of the finished microbial genomes sequenced to date are derived from cultured bacterial and archaeal representatives, the vast majority of microorganisms elude current culturing attempts, severely limiting the ability to recover complete or even partial genomes from these environmental species. Single cell genomics is a novel culture-independent approach, which enables access to the genetic material of an individual cell. No single cell genome has to our knowledge been closed and finished to date. Here we report the completed genome from an uncultured single cell of Candidatus Sulcia muelleri DMIN. Digital PCR on single symbiont cells isolated from the bacteriome of the green sharpshooter Draeculacephala minerva bacteriome allowed us to assess that this bacteria is polyploid with genome copies ranging from approximately 200?900 per cell, making it a most suitable target for single cell finishing efforts. For single cell shotgun sequencing, an individual Sulcia cell was isolated and whole genome amplified by multiple displacement amplification (MDA). Sanger-based finishing methods allowed us to close the genome. To verify the correctness of our single cell genome and exclude MDA-derived artifacts, we independently shotgun sequenced and assembled the Sulcia genome from pooled bacteriomes using a metagenomic approach, yielding a nearly identical genome. Four variations we detected appear to be genuine biological differences between the two samples. Comparison of the single cell genome with bacteriome metagenomic sequence data detected two single nucleotide polymorphisms (SNPs), indicating extremely low genetic diversity within a Sulcia population.

This paper proposes a novel approach to tensor completion, which recovers missing entries of data represented by tensors. The approach is based on the tensor train (TT) rank, which is able to capture hidden information from tensors thanks to its definition from a well-balanced matricization scheme. Accordingly, new optimization formulations for tensor completion are proposed as well as two new algorithms for their solution. The first one called simple low-rank tensor completion via TT (SiLRTC-TT) is intimately related to minimizing a nuclear norm based on TT rank. The second one is from a multilinear matrix factorization model to approximate the TT rank of a tensor, and is called tensor completion by parallel matrix factorization via TT (TMac-TT). A tensor augmentation scheme of transforming a low-order tensor to higher orders is also proposed to enhance the effectiveness of SiLRTC-TT and TMac-TT. Simulation results for color image and video recovery show the clear advantage of our method over all other methods.

Residual activation of the cortex was investigated in nine patients with complete spinal cord injury between T6 and L1 by functional magnetic resonance imaging (fMRI). Brain activations were recorded under four conditions: (1) a patient attempting to move his toes with flexion-extension, (2) a patient imagining the same movement, (3) passive proprio-somesthesic stimulation of the big toes without visual control, and (4) passive proprio-somesthesic stimulation of the big toes with visual control by the patient. Passive proprio-somesthesic stimulation of the toes generated activation posterior to the central sulcus in the three patients who also showed a somesthesic evoked potential response to somesthesic stimulation. When performed under visual control, activations were observed in two more patients. In all patients, activations were found in the cortical areas involved in motor control (i.e., primary sensorimotor cortex, premotor regions and supplementary motor area [SMA]) during attempts to move or mental imagery of these tasks. It is concluded that even several years after injury with some local cortical reorganization, activation of lower limb cortical networks can be generated either by the attempt to move, the mental evocation of the action, or the visual feedback of a passive proprio-somesthesic stimulation.

Influence of radiation therapy on lung tissue in breast cancer patients. CT-assessed density changes 4 years after completion of radiotherapy

1995-01-01

CT-assessed density changes in lung tissues were measured in 22 disease-free breast cancer patients 4 years after completion of radiation therapy. All patients had previously undergone similar CT-examinations before treatment, 3 months, and 9 months after radiotherapy. In patients with visible areas of increased lung density at earlier CT-examinations a decrease of focal findings was observed at 4 years. In patients without focal findings, an increase in density relative to that before therapy was observed. The difference between the mean lung density values among those with visible radiological findings and those without was statistically significant both at 3 and 9 months after therapy. However, this difference did not persist at 4 years. These results may indicate a 2-phase development of radiation-induced lung damages - an acute phase and a late phase; the late phase emerging slowly, and in this study detectable 4 years after completion of radiation therapy.

At present, the standard arrangement of the air cleanup system responsible for emergency tritium recovery from room air is a catalytic oxidation bed with a heater followed by an adsorption bed with a cooler. One disadvantage of this arrangement is that trouble with the heater or the cooler could result in a loss of capacity to recover tritium. Another disadvantage of the catalyst-adsorption-bed arrangement is that tritiated water must be recovered with a high decontamination factor after dilution with a large amount of water vapor in the working atmosphere. The performance of a new arrangement for the air cleanup system, which consists of a precious metal catalyst bed preceded by an adsorption bed without heating equipment, is discussed. According to calculations, most of the tritium released to the room air is recovered in the catalyst bed through oxidation, adsorption, and isotope exchange reaction when the new arrangement is applied. The adsorption bed placed before the catalyst bed dehumidifies the process gas to such a degree that the oxidation reaction of tritium in the catalyst bed is not hindered by water vapor. 15 refs., 6 figs., 6 tabs

Capsule endoscopy (CE) allows direct examination of the small bowel in a safe, noninvasive and well-tolerated manner. Nonetheless, experience indicates failure to reach the cecum in 20-30% of patients within the 8 hour battery life. Attempts to improve the completion rate (CR) as defined by reaching the cecum have been unsuccessful. This study was to investigate the relationship between patients' physical activity and CR. Between January 2009 and January 2010, 76 patients (44 men, 32 women; median age 64.5 yr) underwent CE for the diagnosis of small intestinal disorders. Indications for CE were obscure gastrointestinal bleeding/anemia (62 cases), others (14 cases). Patients were divided into an outpatient group (n=23), mild bed rest group (n=35) and strict bed rest group (n=18). For all patients, the average gastric transit time was 65.5 minutes, small bowel transit time was 301.4 minutes and the CR was 86.8%. However, the CR was 100% (23/23) in the outpatient group, an 85.7% (30/35) in the mild bed rest group, and 72.2% (13/18) in the strict bed rest group. The CR increased with physical activity of patients by Cochran-Armitage Trend Test (p=0.009). In multivariate logistic regression analyses, low physical activity was a significant risk factor for failure to reach the cecum during CE examination; adjusted OR: 3.39, 95% CI: 1.01-11.42 (p=0.048). Our observations suggested that increasing physical activity would increase the likelihood of a complete bowel examination by CE. Further, for CE, inconvenient bowel preparations like the use of polyethylene glycol may be avoided.

Viral marketing is a marketing strategy utilizes social media to spread information about a product or services provided. It is the most powerful way to share information in a short amount of time. The objective of this study is to investigate the dynamic of viral marketing within a time duration in the point of view of mathematics. This study used the epidemiological model known as Susceptible-Infected-Recovered (SIR). The model consists of a system of three differential equations with three state variables namely susceptible (S), infected (I) and recovered (R). It considers a case of SIR model with demography. Numerical experiments have been performed. The results show that viral marketing reaches its peak within two days. The online messages shared will become higher if the initial number of the infected individual has been increased.

Background: Previous studies of patients with surgically resected non-small cell lung cancer and chest wall invasion have shown conflicting results with respect to prognosis. Whether high-risk subsets of the T3 N0 M0 population exist with respect to patterns of failure and overall survival has been difficult to ascertain, owing to small numbers of patients in most series. Methods and Materials: A retrospective review was performed to determine patterns of failure and overall survival for patients with completely resected T3 N0 M0 non-small cell lung cancer. From 1979 to 1993, 92 evaluable patients underwent complete resection for T3 N0 M0 non-small cell lung cancer. The following potential prognostic factors were recorded from the history: tumor size, location, grade, histology, patient age, use of adjuvant radiation therapy (18 of 92 patients), and type of surgical procedure (chest wall or extrapleural resection). Results: The actuarial 2- and 4-year overall survival rates for the entire cohort were 48% and 35%, respectively. The actuarial local control at 4 years was 94%. Neither the type of surgical procedure performed nor the addition of thoracic radiation therapy impacted local control or overall survival. Conclusion: Patients with completely resected T3 N0 M0 non-small cell lung cancer have similar local control and overall survival irrespective of primary location, type of surgery performed, or use of adjuvant radiation therapy. Additionally, the tumor recurrence rate and overall survival found in this study support the placement of this group of patients in Stage IIB of the 1997 AJCC lung staging classification

Complete Remission Obtained with Azacitidine in a Patient with Concomitant Therapy Related Myeloid Neoplasm and Pulmonary Mucormycosis

Full Text Available Mucormycosis is the third cause of invasive mycosis after candidiasis and aspergillosis in AML patients, representing a poor prognostic factor associated with a high rate of fatal outcome. We report  a case of a patient with AML and a concomitant pulmonary mucormycosis at diagnosis,  who obtained a  complete remission both of her AML and of the fungal infection. The incidence of the infection at the onset of leukemia is extremely unusual, and, to our knowledge, the sporadic cases reported in the literature are included in heterogeneous series retrospectively examined. In our case, Liposomal Amphotericin B as single agent appeared incapable of controlling the infection, so anti-infective therapy was intensified with posaconazole and simultaneously antileukemic treatment with 5-azacitidine was started, with the understanding that the only antifungal treatment would not have been able to keep the infection under control for a long time if not associated with a reversal of neutropenia related to the disease. We observed a progressive improvement of the general conditions, a healing of pneumonia and a complete remission of the leukemic disease, suggesting that a careful utilization of the new compounds available today, in terms of both antifungal and antileukemic treatment, may offer a curative chance a patient who would have otherwise been considered unfit for a potentially curative therapeutic strategy.

Bradycardia during Induction Therapy with All-trans Retinoic Acid in Patients with Acute Promyelocytic Leukemia: Case Report and Literature Review

2018-01-01

Full Text Available A 41-year-old man with newly diagnosed acute promyelocytic leukemia (APL received induction chemotherapy, containing all-trans retinoic acid (ATRA, idarubicin, and arsenic trioxide. On the 11th day of therapy, he experienced complete atrioventricular (AV block; therefore, ATRA and arsenic trioxide were immediately postponed. His heart rate partially recovered, and ATRA was rechallenged with a half dose. However, complete AV block as well as differentiation syndrome recurred on the next day. ATRA was immediately discontinued, and a temporary pacemaker was inserted. Two days after discontinuing ATRA, AV block gradually improved, and ATRA was uneventfully rechallenged again. The Naranjo adverse drug reaction probability scale was 7 for ATRA, suggesting it was the probable cause of arrhythmia. A literature search identified 6 other cases of bradycardia during ATRA therapy, and all of them occurred during APL induction therapy, with onset ranging from 4 days to 25 days. Therefore, monitoring vital signs and performing electrocardiogram are highly recommended during the first month of induction therapy with ATRA. ATRA should be discontinued if complete AV block occurs. Rechallenging with ATRA can be considered in fully recovered and clinically stable patients.

Purpose: To investigate the changes in salivary function and oral health-related quality of life for patients with nasopharyngeal carcinoma treated by intensity-modulated radiotherapy (IMRT). Methods and Materials: A total of 57 patients with early-stage nasopharyngeal carcinoma received IMRT. The parotid and whole saliva flow was measured, and the Medical Outcomes Study 36-item short form, European Organization for Research and Treatment of Cancer Quality of Life questionnaire-C30, European Organization for Research and Treatment of Cancer Quality of Life questionnaire 35-item head-and-neck module, and Oral Health Impact Profile questionnaires were completed at baseline and 2, 6, 12, 18, and 24 months after IMRT. Results: Parotid saliva flow recovered fully after 1 year and maintained. Whole saliva flow recovered partially to 40% of baseline. A general trend of deterioration in most quality of life scales was observed after IMRT, followed by gradual recovery. Persistent oral-related symptoms were found 2 years after treatment. Conclusion: IMRT for early-stage nasopharyngeal carcinoma could only partially preserve the whole salivary function and oral health-related quality of life.

Process of recovering shale oil

Energy Technology Data Exchange (ETDEWEB)

1949-01-17

A process is disclosed for recovering oil from shale rock by means of channels cut in the shale deposit, to which heat is carried for warming the shale mass and which are separated from the fume channels formed in the shale by parts of the shale rock, characterized in that heating elements are put down in the heating channels, which occupy less cross section than these channels, and in the so-formed space between the channel wall and the heating element a filling is placed, which facilitates heat transfer between the heating element and the shale and simultaneously prevents a streaming of the oily product gasified out of the shale from working into the heating element and stopping it.

Tomlinson, R.E.

1968-01-01

Reward bands placed on the other leg of certain regularly banded immature mourning doves (Zenaidura macroura) were used to develop information on reporting rates of recovered dove bands. Reports from 15 widely separated sections of the United States showed considerable variation in recovery rate of doves both with and without reward bands. The overall percentages of banded doves that were reported as recovered were 9.69% for those with reward bands and 3.83% for controls. The bandreporting rate for states influenced by publicity was 66%; that for states not influenced was 32%.

We consider the inverse problem of recovering the shape, location and surface properties of an object where the surrounding medium is both conductive and homogeneous and we measure Cauchy data on an accessible part of the exterior boundary. It is assumed that the physical situation is modelled by harmonic functions and the boundary condition on the obstacle is one of Dirichlet type. The purpose of this paper is to answer some of the questions raised in a recent paper that introduced a nonlinear integral equation approach for the solution of this type of problem.

To assess outcomes of treating completely edentulous patients with a fixed implant-supported profile prosthesis utilizing a graftless approach for the maxilla and for the mandible, with emphasis on clinically related outcomes, specifically implant and prosthesis survival. This was a retrospective study with the following inclusion criteria: completely edentulous patients rehabilitated with a fixed implant-supported profile denture utilizing a graftless approach. Patients fulfilling the inclusion criteria were asked to participate in the study during their follow-up visits, and hence a consecutive sampling strategy was used. Data regarding implant and prosthesis cumulative survival rates (CSRs) were gathered and calculated. Thirty-four patients were identified with a total of 220 implants placed. An overall CSR of 98.2% was recorded with an observation of up to 10 years. For tilted, axial, and zygomatic implants, CSRs of 96.9%, 98.0%, and 100%, respectively, were observed for up to 10 years. For provisional prostheses, CSRs of 92.3% at 1 year, and 84.6% at 2 years were observed. For final prostheses, a CSR of 93.8% was observed at 10 years. The results suggest that treating completely edentulous patients with a fixed profile prosthesis utilizing a graftless approach in the maxilla and the mandible can be a reliable treatment option.

Facial development of patients with unilateral complete cleft lip and palate (UCLP) is associated with many problems including deformity of the palate. The aim of this study was to evaluate palatal morphology and variability in patients with UCLP compared with Czech norms using methods of geometric morphometrics. The study was based on virtual dental cast analysis of 29 UCLP patients and 29 control individuals at the age of 15 years. The variability of palatal shape in UCLP patients was greater than that in nonclefted palates. Only 24% of clefted palates fell within the variability of controls. The palatal form of UCLP patients (range from 11.8 to 17.2 years) was not correlated with age. Compared with control palates, palates of UCLP patients were narrower, more anteriorly than posteriorly. Apart from the praemaxilla region, they were also shallower, and the difference increased posteriorly. The UCLP palate was characterised by the asymmetry of its vault. The maximum height of the palatal vault was anterior on the clefted side, whereas it was posterior on the nonclefted side. The slope of the UCLP palate was more inclined compared with the control group. The praemaxilla was therefore situated more inferiorly.

Susceptible-infected-recovered epidemics in random networks with population awareness

Science.gov (United States)

Wu, Qingchu; Chen, Shufang

2017-10-01

The influence of epidemic information-based awareness on the spread of infectious diseases on networks cannot be ignored. Within the effective degree modeling framework, we discuss the susceptible-infected-recovered model in complex networks with general awareness and general degree distribution. By performing the linear stability analysis, the conditions of epidemic outbreak can be deduced and the results of the previous research can be further expanded. Results show that the local awareness can suppress significantly the epidemic spreading on complex networks via raising the epidemic threshold and such effects are closely related to the formulation of awareness functions. In addition, our results suggest that the recovered information-based awareness has no effect on the critical condition of epidemic outbreak.

Full Text Available Although neurological manifestations associated with dengue viruses (DENV infection have been reported, there is very limited information on the genetic characteristics of neurotropic DENV. Here we describe the isolation and complete genome analysis of DENV serotype 3 (DENV-3 from cerebrospinal fluid of an encephalitis paediatric patient in Jakarta, Indonesia. Next-generation sequencing was employed to deduce the complete genome of the neurotropic DENV-3 isolate. Based on complete genome analysis, two unique and nine uncommon amino acid changes in the protein coding region were observed in the virus. A phylogenetic tree and molecular clock analysis revealed that the neurotropic virus was a member of Sumatran-Javan clade of DENV-3 genotype I and shared a common ancestor with other isolates from Jakarta around 1998. This is the first report of neurotropic DENV-3 complete genome analysis, providing detailed information on the genetic characteristics of this virus.

2015-07-01

This work aims to confirm if implant-supported overdentures are a good treatment option for edentulous patients and offer an improvement in quality of life compared with traditional complete prostheses (dentures). This retrospective clinical descriptive study included three evaluation groups: validation group (n=57); control group of patients with complete removeable prostheses (n=56); study group of patients with implant-supported overdentures retained with the Locator® system (n=80). The study also validated the Oral Health Impact Profile-20 questionnaire. Individual protocols were created that included socio-demographic data, the Oral Health Impact Profile-20 (OHIP-20) questionnaire and Oral Satisfaction Scale (OSS). Descriptive and bivariate statistical analysis was carried out applying χ², Pearson, Kruskal-Wallis, and Student t tests, transferring data into SPSS-Windows® software from a Microsoft® Excel spreadsheet. The OHIP-20 proved to be a valid instrument and provided reliable assessment of health-related quality of life among both the Spanish general population and edentulous patients. The control and study groups proved comparable, showing socio-demographic homogeneity. For patients with overdentures retained by means of the Locator® system, these restorations had significantly lower impact on quality of life (19 vs 33), both generally and for each individual questionnaire item, and much higher satisfaction with the state of their oral cavities (8.3 vs 5.3) than patients wearing dentures; both sets of data showed a direct linear relationship, so that as the level of impact on quality of life increased, perceived oral satisfaction worsened. Patients rehabilitated with implant supported overdentures retained by the Locator® system, presented significantly lower levels of impact on their quality of life and significantly higher oral satisfaction than patients with conventional complete prostheses.

When will the Antarctic Ozone Hole Recover?

Science.gov (United States)

Newman, Paul A.; Nash, Eric R.; Kawa, S. Randolph; Montzka, Steve

2006-01-01

The Antarctic ozone hole develops each year and culminates by early Spring. Antarctic ozone values have been monitored since 1979 using satellite observations from the .TOMS instrument. The severity of the hole has been assessed from TOMS using the minimum total ozone value from the October monthly mean (depth of the hole) and by calculating the average size during the September-October period. Ozone is mainly destroyed by halogen catalytic cycles, and these losses are modulated by temperature variations in the collar of the polar lower stratospheric vortex. In this presentation, we show the relationships of halogens and temperature to, both the size and depth of the hole. Because atmospheric halogen levels are responding to international agreements that limit or phase out production, the amount of halogens in the stratosphere should decrease over the next few decades. Using projections of halogen levels combined with age-of-air estimates, we find that the ozone hole is recovering at an extremely slow rate and that large ozone holes will regularly recur over the next 2 decades. The ozone hole will begin to show first signs of recovery in about 2023, and the hole will fully recover to pre-1980 levels in approximately 2070. This 2070 recovery is 20 years later than recent projections.

The aim of this study was to compare clonal diversity and carbapenemase-encoding genes of A. baumannii isolates collected from colonized or infected patients and hospital environment in two intensive care units (ICUs in Morocco. Methods The patient and environmental sampling was carried out in the medical and surgical ICUs of Mohammed V Military teaching hospital from March to August 2015. All A. baumannii isolates recovered from clinical and environmental samples, were identified using routine microbiological techniques and Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry. Antimicrobial susceptibility testing was performed using disc diffusion method. The carbapenemase-encoding genes were screened for by PCR. Clonal relatedness was analyzed by digestion of the DNA with low frequency restriction enzymes and pulsed field gel electrophoresis (PFGE and the multi locus sequence typing (MLST was performed on two selected isolates from two major pulsotypes. Results A total of 83 multidrug-resistant A. baumannii isolates were collected: 47 clinical isolates and 36 environmental isolates. All isolates were positive for the bla OXA51-like and bla OXA23-like genes. The coexistence of bla NDM-1 /bla OXA-23-like and bla OXA 24-like /bla OXA-23-like were detected in 27 (32.5% and 2 (2.4% of A. baumannii isolates, respectively. The environmental samples and the fecally-colonized patients were significantly identified (p < 0.05 as the most common sites of isolation of NDM-1-harboring isolates. PFGE grouped all isolates into 9 distinct clusters with two major groups (0007 and 0008 containing up to 59% of the isolates. The pulsotype 0008 corresponds to sequence type (ST 195 while pulsotype 0007 corresponds to ST 1089.The genetic similarity between the clinical and environmental isolates

Type C1 botulism outbreaks in Black-faced Spoonbills (Platalea minor) occurred in Taiwan from 2002 to 2003, and hematologic and biochemistry parameters from botulism-paralyzed birds and recovered birds were compared. Values for creatinine and uric acid were higher (Pbirds with botulism than in recovered birds. Lower white blood cell counts (Pbirds. Based on these observations, we suggest that hematologic and biochemistry analyses should be performed to assess the health condition of birds recovering from botulism.

Restoration of facial symmetry in a patient with bell palsy using a modified maxillary complete denture: a case report.

Science.gov (United States)

Bagchi, Gautam; Nath, Dilip Kumar

2012-01-01

Permanent facial paralysis can be devastating for a patient. Modern society's emphasis on appearance and physical beauty contributes to this problem and often leads to isolation of patients embarrassed by their appearance. Lagophthalmos with ocular exposure, loss of oral competence with resultant drooling, alar collapse with nasal airway obstruction, and difficulties with mastication and speech production are all potential consequences of facial paralysis. Affected patients are confronted with both a cosmetic defect and the functional deficits associated with loss of facial nerve function. In this case history report, a modified maxillary complete denture permitted a patient with Bell palsy to carry on daily activities with minimal facial distortion, pain, speech difficulty, and associated emotional trauma.

Trials failed to demonstrate additional value of completion axillary lymph node dissection in case of limited sentinel lymph node metastases in breast cancer patients undergoing breast conserving therapy. It has been suggested that the low regional recurrence rates in these trials might partially be ascribed to accidental irradiation of part of the axilla by whole breast radiation therapy, which precludes extrapolation of results to mastectomy patients. The aim of the randomized controlled BOOG 2013–07 trial is therefore to investigate whether completion axillary treatment can be safely omitted in sentinel lymph node positive breast cancer patients treated with mastectomy. This study is designed as a non-inferiority randomized controlled multicentre trial. Women aged 18 years or older diagnosed with unilateral invasive clinically T1-2 N0 breast cancer who are treated with mastectomy, and who have a maximum of three axillary sentinel lymph nodes containing micro- and/or macrometastases, will be randomized for completion axillary treatment versus no completion axillary treatment. Completion axillary treatment can consist of completion axillary lymph node dissection or axillary radiation therapy. Primary endpoint is regional recurrence rate at 5 years. Based on a 5-year regional recurrence free survival rate of 98 % among controls and 96 % for study subjects, the sample size amounts 439 per arm (including 10 % lost to follow-up), to be able to reject the null hypothesis that the rate for study and control subjects is inferior by at least 5 % with a probability of 0.8. Results will be reported after 5 and 10 years of follow-up. We hypothesize that completion axillary treatment can be safely omitted in sentinel node positive breast cancer patients undergoing mastectomy. If confirmed, this study will significantly decrease the number of breast cancer patients receiving extensive treatment of the axilla, thereby diminishing the risk of morbidity and improving quality of

Real sea experiment for the recovery of significant metals such as uranium and vanadium which dissolved in seawater with extremely low concentration has been carried out at the offing of Mutsu establishment to evaluate the adsorption performance of adsorbent synthesized by radiation-induced graft-polymerization. The significant metals of uranium and vanadium eluted from the adsorbent which was soaked in the real sea were adsorbed onto the conventional chelate resin. The chelate resin which adsorbed the metals was packed in a plastic (PVC) column and further put in a cylindrical stainless transport container. This container was transported to the facility for separation and purification by a truck for the exclusive loading. Then the recovers metals were purified there. The recovered metals contained the uranium of 150g (1.92 MBq) and less in one recovery experiment. The maximum concentration is 60 Bq/g when the uranium is adsorbed on the chelate resin. Transport of recovered metals can be treated as general substance since these amount and concentration are out of legal control. However, the recovered metals were transported in conformity to L type Transport as a voluntary regulation. Though there is no requirements of structural strength for L type package legally, the structural strength of container was designed on that of IP-2 type which is higher transport grade than L type to take its safety measure. Its strength analysis proved the safety under general transport process. The transport was based on the plan made in advance. (author)

Introduction: The purpose of this study was to evaluate the single-centre experience with transvenous coil treatment of dural carotid-cavernous sinus fistulas. Methods: Between November 1991 and December 2005, a total of 141 patients (112 female) with dural carotid-cavernous sinus fistula underwent 161 transvenous treatment sessions. The patient files and angiograms were analysed retrospectively. Clinical signs and symptoms included chemosis (94%), exophthalmos (87%), cranial nerve palsy (54%), increased intraocular pressure (60%), diplopia (51%), and impaired vision (28%). Angiography revealed in addition cortical drainage in 34% of the patients. Partial arterial embolization was carried out in 23% of the patients. Transvenous treatment comprised in by far the majority of patients complete filling of the cavernous sinus and the adjacent segment of the superior and inferior ophthalmic vein with detachable coils. Complete interruption of the arteriovenous shunt was achieved in 81% of the patients. A minor residual shunt (without cortical or ocular drainage) remained in 13%, a significant residual shunt (with cortical or ocular drainage) remained in 4%, and the attempted treatment failed in 2%. There was a tendency for ocular pressure-related symptoms to resolve rapidly, while cranial nerve palsy and diplopia improved slowly (65%) or did not change (11%). The 39 patients with visual impairment recovered within the first 2 weeks after endovascular treatment. After complete interruption of the arteriovenous shunt, no recurrence was observed. The transvenous coil occlusion of the superior and inferior ophthalmic veins and the cavernous sinus of the symptomatic eye is a highly efficient and safe treatment in dural carotid-cavernous sinus fistulas. In the majority of patients a significant and permanent improvement in clinical signs and symptoms can be achieved. (orig.)

In this study, resonance and articulation disorders were examined in a group of patients surgically treated for cleft lip and palate, considering family social background, and children's ability of self monitoring their speech output while speaking. Fifty children (32 males and 18 females) mean age 6.5 ± 1.6 years, affected by non-syndromic complete unilateral cleft of the lip and palate underwent the same surgical protocol. The speech level was evaluated using the Accordi's speech assessment protocol that focuses on intelligibility, nasality, nasal air escape, pharyngeal friction, and glottal stop. Pearson product-moment correlation analysis was used to detect significant associations between analysed parameters. A total of 16% (8 children) of the sample had severe to moderate degree of nasality and nasal air escape, presence of pharyngeal friction and glottal stop, which obviously compromise speech intelligibility. Ten children (10%) showed a barely acceptable phonological outcome: nasality and nasal air escape were mild to moderate, but the intelligibility remained poor. Thirty-two children (64%) had normal speech. Statistical analysis revealed a significant correlation between the severity of nasal resonance and nasal air escape (p ≤ 0.05). No statistical significant correlation was found between the final intelligibility and the patient social background, neither between the final intelligibility nor the age of the patients. The differences in speech outcome could be explained with a specific, subjective, and inborn ability, different for each child, in self-monitoring their speech output.

Cell culture models are essential for the detailed study of molecular processes. We analyze the dynamics of changes in a culture model of bovine granulosa cells. The cells were cultured for up to 8 days and analyzed for steroid production and gene expression. According to the expression of the marker genes CDH1, CDH2 and VIM, the cells maintained their mesenchymal character throughout the time of culture. In contrast, the levels of functionally important transcripts and of estradiol and progesterone production were rapidly down-regulated but showed a substantial up-regulation from day 4. FOXL2, a marker for granulosa cell identity, was also rapidly down-regulated after plating but completely recovered towards the end of culture. In contrast, expression of the Sertoli cell marker SOX9 and the lesion/inflammation marker PTGS2 increased during the first 2 days after plating but gradually decreased later on. We conclude that only long-term culture conditions (>4 days) allow the cells to recover from plating stress and to re-acquire characteristic granulosa cell features.

Full Text Available Abstract Background Bone mineral density (BMD accrual during childhood and adolescence is important for attaining peak bone mass. BMD decrements have been reported in survivors of childhood bone sarcomas. However, little is known about the onset and development of bone loss during cancer treatment. The objective of this cross-sectional study was to evaluate BMD in newly diagnosed Ewing's and osteosarcoma patients by means of dual-energy x-ray absorptiometry (DXA after completion of neoadjuvant chemotherapy. Methods DXA measurements of the lumbar spine (L2-4, both femora and calcanei were performed perioperatively in 46 children and adolescents (mean age: 14.3 years, range: 8.6-21.5 years. Mean Z-scores, areal BMD (g/cm2, calculated volumetric BMD (g/cm3 and bone mineral content (BMC, g were determined. Results Lumbar spine mean Z-score was -0.14 (95% CI: -0.46 to 0.18, areal BMD was 1.016 g/cm2 (95% CI: 0.950 to 1.082 and volumetric BMD was 0.330 g/cm3 (95% CI: 0.314 to 0.347 which is comparable to healthy peers. For patients with a lower extremity tumor (n = 36, the difference between the affected and non-affected femoral neck was 12.1% (95% CI: -16.3 to -7.9 in areal BMD. The reduction of BMD was more pronounced in the calcaneus with a difference between the affected and contralateral side of 21.7% (95% CI: -29.3 to -14.0 for areal BMD. Furthermore, significant correlations for femoral and calcaneal DXA measurements were found with Spearman-rho coefficients ranging from ρ = 0.55 to ρ = 0.80. Conclusions The tumor disease located in the lower extremity in combination with offloading recommendations induced diminished BMD values, indicating local osteopenia conditions. However, the results revealed no significant decrements of lumbar spine BMD in pediatric sarcoma patients after completion of neoadjuvant chemotherapy. Nevertheless, it has to be taken into account that bone tumor patients may experience BMD decrements or secondary osteoporosis

This invention relates to a process for recovering tungsten from an alkaline leaching solution of tungsten ores. This invention comprises adjusting the pH of an alkaline leaching solution which is obtained by lixiviating ore containing tungsten with an alkaline solution to 7--8 with acid to oxidize molybdic acid ions in the solution, adding a sulfide donor, then precipitating molybdenum sulfide compounds by adjusting the pH value of the solution to 2--3. Tungstic acid ions are recovered as calcium tungstate by the addition of a calcium ion donor after the molybdenum sulfide compounds are separated

METHOD OF RECOVERING URANIUM COMPOUNDS

Science.gov (United States)

Poirier, R.H.

1957-10-29

S>The recovery of uranium compounds which have been adsorbed on anion exchange resins is discussed. The uranium and thorium-containing residues from monazite processed by alkali hydroxide are separated from solution, and leached with an alkali metal carbonate solution, whereby the uranium and thorium hydrorides are dissolved. The carbonate solution is then passed over an anion exchange resin causing the uranium to be adsorbed while the thorium remains in solution. The uranium may be recovered by contacting the uranium-holding resin with an aqueous ammonium carbonate solution whereby the uranium values are eluted from the resin and then heating the eluate whereby carbon dioxide and ammonia are given off, the pH value of the solution is lowered, and the uranium is precipitated.

Manufacturing of Nano gold cosmetics was done at PT. Gizi Indonesia. Clinical trials to cosmetics data supported that cosmetics are able to treat skin health which has been reported partially. For special cases, the recovery process of facial skin damage should also receive attention including cases of facial skin damage caused by chemicals such as phenol, HCl, aqua regia or other harsh chemicals. The problem determined whether the Nano gold is able to recover skin damage due to the harsh chemicals. This clinical trial data on the forms of early skin damage caused by phenol was delivered in the forms of facial photos patients. The recovery progress of facial skin condition was obtained every week for two months. The data included the forms of widespread wounds during the recovery process. This statement supported by anova statistical analysis of the widespread wound changing every week for 8 times. The conclusion is skin damage due to Phenol impregnation can be recovered with the use of Nano gold cosmetics for 8 weeks. This results support the manufacturing of Nano gold cosmetics for the needs of society. It also suggest that Nano gold material can be used for medicine manufacturing in the future.

This study adopted a developmental perspective on recovery from conflict in romantic relationships. Participants were 73 young adults (target participants), studied since birth, and their romantic partners. A novel observational coding scheme was used to evaluate each participant's degree of conflict recovery, operationalized as the extent to which the participant disengaged from conflict during a 4-min "cool-down" task immediately following a 10-min conflict discussion. Conflict recovery was systematically associated with developmental and dyadic processes. Targets who were rated as securely attached more times in infancy recovered from conflict better, as did their romantic partners. Concurrently, having a romantic partner who displayed better recovery predicted more positive relationship emotions and greater relationship satisfaction. Prospectively, target participants' early attachment security and their partners' degree of conflict recovery interacted to predict relationship stability 2 years later, such that having a partner who recovered from conflict better buffered targets with insecure histories.

For recovering precious metals from waste printed circuit boards (PCBs), a novel hybrid technology including physical and biological methods was developed. It consisted of crushing, corona-electrostatic separation, and bioleaching. Bioleaching process is the focus of this paper. A novel bioreactor for bioleaching was designed. Bioleaching was carried out using Pseudomonas chlororaphis. Bioleaching experiments using mixed particles of Au and Cu were performed and leachate contained 0.006 mg/L, 2823 mg/L Au+ and Cu2+ respectively. It showed when Cu existed, the concentrations of Au were extremely small. This provided the feasibility to separate Cu from Au. The method of orthogonal experimental design was employed in the simulation bioleaching experiments. Experimental results showed the optimized parameters for separating Cu from Au particles were pH 7.0, temperature 22.5 °C, and rotation speed 80 r/min. Based on the optimized parameters obtained, the bioreactor was operated for recovering mixed Au and Cu particles. 88.1 wt.% of Cu and 76.6 wt.% of Au were recovered. The paper contributed important information to recover precious metals from waste PCBs. PMID:26316021

We report 3 cases of durable complete response (CR) in patients with BRAF-mutated metastatic melanoma who were initially treated unsuccessfully with sequential immunotherapies (high dose interleukin 2 followed by ipilimumab with or without concurrent radiation therapy). After progression during or post immunotherapy, these patients were given BRAF inhibitor therapy and developed rapid CRs. Based on the concomitant presence of autoimmune manifestations (including vitiligo and hypophysitis), we postulated that there was a synergistic effect between the prior immune therapy and the BRAF targeting agents. Accordingly, the inhibitors were gradually weaned off beginning at 3 months and were stopped completely at 9-12 months. The three patients remain well and in CR off of all therapy at up to 15 months radiographic follow-up. The institution of the BRAF therapy was associated with development of severe rheumatoid-like arthritis in 2 patients which persisted for months after discontinuation of therapy, suggesting it was not merely a known toxicity of BRAF inhibitors (arthralgias). On immunologic analysis, these patients had high levels of non-T-regulatory, CD4 positive effector phenotype T-cells, which persisted after completion of therapy. Of note, we had previously reported a similar phenomenon in patients with metastatic melanoma who failed high dose interleukin-2 and were then placed on a finite course of temozolomide with rapid complete responses that have remained durable for many years after discontinuation of temozolomide. We postulate that a finite course of cytotoxic or targeted therapy specific for melanoma given after apparent failure of prior immunotherapy can result in complete and durable remissions that may persist long after the specific cytotoxic or targeted agents have been discontinued suggesting the existence of sequence specific synergism between immunotherapy and these agents. Here, we discuss these cases in the context of the literature on

This is the third and final part of the three-part article written to describe the mass, energy and material balances of the solid recovered fuel production process produced from various types of waste streams through mechanical treatment. This article focused the production of solid recovered fuel from municipal solid waste. The stream of municipal solid waste used here as an input waste material to produce solid recovered fuel is energy waste collected from households of municipality. This article presents the mass, energy and material balances of the solid recovered fuel production process. These balances are based on the proximate as well as the ultimate analysis and the composition determination of various streams of material produced in a solid recovered fuel production plant. All the process streams are sampled and treated according to CEN standard methods for solid recovered fuel. The results of the mass balance of the solid recovered fuel production process showed that 72% of the input waste material was recovered in the form of solid recovered fuel; 2.6% as ferrous metal, 0.4% as non-ferrous metal, 11% was sorted as rejects material, 12% as fine faction and 2% as heavy fraction. The energy balance of the solid recovered fuel production process showed that 86% of the total input energy content of input waste material was recovered in the form of solid recovered fuel. The remaining percentage (14%) of the input energy was split into the streams of reject material, fine fraction and heavy fraction. The material balances of this process showed that mass fraction of paper and cardboard, plastic (soft) and wood recovered in the solid recovered fuel stream was 88%, 85% and 90%, respectively, of their input mass. A high mass fraction of rubber material, plastic (PVC-plastic) and inert (stone/rock and glass particles) was found in the reject material stream. © The Author(s) 2014.

How telling stories helps patients to recover psychologically after intensive care.

Science.gov (United States)

Williams, Susan Lecky

Studies have shown both the risk of post traumatic stress following intensive care unit treatment, and the helpfulness of telling trauma stories for psychological recovery. This article is based on recent doctoral research exploring the impact of unexpected life threatening events after admission to hospital. The original research used a qualitative design blending discourse, narrative and phenomenological approaches, guided by sensitivity to participants' evolving work of pulling stories together. Patients chosen from ICU discharge summaries showing a critical life threatening event after admission gave unstructured interviews soon after discharge from hospital and a year later. This article focuses on one particular finding, showing that critical illness can make it difficult for patients to construct personal stories of their experience. Limited evidence suggested overcoming those difficulties meant they had an improved sense of wellbeing a year after discharge. Stories are an essential way in which humans make sense of their experience, which is crucial both for responding appropriately and for personal wellbeing following traumatic life events. Therefore, difficulties in "storying" significant experience can have a negative impact on wellbeing. Some patients need help piecing together stories of their critical illness experience.

Goodyear-Smith, F A; Laidlaw, T M; Large, R G

1998-06-26

To survey New Zealand families where an alleged perpetrator and/or other family member denies an accusation involving the childhood molestation of one family member by another, based on a memory recovered in adulthood. As the validity of such memories is crucial, our aim was to develop a profile of such families and to compare it with New Zealand epidemiological data. Information was collected by questionnaire regarding family demographics, characteristics of the accuser, family life, events surrounding and leading up to the accusations, consequences of the accusations and details of the accuser's current life situation. The 73 subjects included fathers, mothers, siblings and other relatives of the accusing adults. Most accusers were highly educated white women, frequently first born or older children from relatively large families, statistically different proportions from those expected. Many accusations involved events of low base-rate probability including satanic ritual abuse. Proportions differed from those of another New Zealand prevalence survey of 1019 18-year-olds in almost every way. The data suggest that it is unlikely that many, if not most, of the memories of child sexual abuse recovered in adulthood are a true reflection of history. Memories recovered during therapy should be treated with respect as part of the patient's narrative truth, but not assumed to be factually accurate without corroborative evidence.

Gildea, Chris M; Lantaff, Wendy M; Olenik, Nicole L

The objective of this study was to identify patient-perceived barriers to achieving A1C targets after receiving instruction in an accredited diabetes education program. Qualitative research using semistructured interviews and thematic analyses. One pharmacist-run diabetes center located within an independent community pharmacy in a suburban region of southern Indiana. A total of 17 participants between the ages of 41-78 were interviewed in March and April 2016. Not applicable. Patient-perceived barriers to attaining glycemic control after completion of a pharmacist-taught diabetes self-management education (DSME) program accredited by the American Association of Diabetes Educators. Participants reported a variety of perceived barriers to glycemic control subsequent to the receipt of structured education. Seven major themes emerged: 1) health care provider factors; 2) self-identified indiscretions; 3) psychological barriers and poor social support; 4) knowledge deficits; 5) personal injury or adverse drug events; 6) time constraints and competing life demands; and 7) financial constraints. Participants reported a variety of perceived barriers to achieving A1C targets after completing DSME. Incorporation of solutions and coping mechanisms to these barriers into diabetes education programs may help patients attain glycemic control. Other factors may require individualized attention outside of DSME in follow-up episodes of diabetes care. Copyright © 2017 American Pharmacists Association®. Published by Elsevier Inc.

Cardiac rehabilitation has a number of benefits for patients, yet participation in it is sub-optimal, especially in regional Australia. Innovative models of cardiac rehabilitation are needed to improve participation. Providing nurse mentors to support patients transitioning from hospital to home represents a new model of service delivery in Australia. To explore the impact of a home-based cardiac rehabilitation program in assisting patients to recover from Acute Coronary Syndrome and meeting the expectations of nurse mentors delivering the program. This case study was underpinned by the structure, process and outcomes model and occurred in three Australian hospitals 2008-2011. Thirteen patients recovering from acute coronary syndrome were interviewed by telephone and seven nurse mentors completed a survey after completing the program. Mentor perceptions concerning the structures of the home-based CR program included the timely recruitment of patients, mentor training to operationalise the program, commitment to development of the mentor role, and the acquisition of knowledge and skills about cognitive behavioural therapy and patient centred care. Processes included the therapeutic relationship between mentors and patients, suitability of the program and the promotion of healthier lifestyle behaviours. Outcomes identified that patients were satisfied with the program's audiovisual resources, and the level of support and guidance provided by their nurse mentors. Mentors believed that the program was easy to use in terms of its delivery. Patients believed the program assisted their recovery and were satisfied with the information, guidance and support received from mentors. There were positive signs that the program influenced patients' decisions to change unhealthy lifestyle behaviours. Outcomes highlighted both rewards and barriers associated with mentoring patients in their homes by telephone. Experience gained from developing a therapeutic relationship with

2018-05-01

Multi-label learning is a common machine learning problem arising from numerous real-world applications in diverse fields, e.g, natural language processing, bioinformatics, information retrieval and so on. Among various multi-label learning methods, the matrix completion approach has been regarded as a promising approach to transductive multi-label learning. By constructing a joint matrix comprising the feature matrix and the label matrix, the missing labels of test samples are regarded as missing values of the joint matrix. With the low-rank assumption of the constructed joint matrix, the missing labels can be recovered by minimizing its rank. Despite its success, most matrix completion based approaches ignore the smoothness assumption of unlabeled data, i.e., neighboring instances should also share a similar set of labels. Thus they may under exploit the intrinsic structures of data. In addition, the matrix completion problem can be less efficient. To this end, we propose to efficiently solve the multi-label learning problem as an enhanced matrix completion model with manifold regularization, where the graph Laplacian is used to ensure the label smoothness over it. To speed up the convergence of our model, we develop an efficient iterative algorithm, which solves the resulted nuclear norm minimization problem with the alternating direction method of multipliers (ADMM). Experiments on both synthetic and real-world data have shown the promising results of the proposed approach. Copyright © 2018 Elsevier Ltd. All rights reserved.

1990-01-01

Approximately 5000 sandhill cranes (Grus canadensis ) died from undetermined causes in Gains County, Texas, 1985, and an additional 200 died in 1986. Prominent clinical signs were the inability of many sick cranes to hold their necks horizontal and the neck, head, and legs sometimes drooped perpendicularly during flight. Approximately 95% of the dead cranes' gizzards contained peanuts. Culturing of peanuts, shells, soil and soil debris from fields in which sandhill cranes died showed that Fusarium species were the fungi most frequently isolated and eight species were recovered from these substrates. Fusarium compactum, F. solani , and F. equiseti were the only species recovered from all substrates cultured from both fields.

Facial nerve disorders may be of sudden onset and more often of unknown etiology. Edema of the facial nerve within the fallopian canal results in Bell's palsy. This causes compression of the nerve and affects the microcirculation. Many authors have suggested treatment for facial nerve paralysis ranging from simple physiotherapy to complicated microvascular decompression. It more often results in symptoms like synkinesis and muscle spasm after the decompression surgery of the nerve because of the inability to arrange the nerve fibers within the canal. The treatment choice also depends on patient's age, extent of the nerve damage, and patient's needs and desires. Many patients who cannot be rehabilitated functionally can be treated for esthetics of the involved muscles. This case report elaborates about a patient who was rehabilitated for esthetics and to some extent for function.

Greater anterior insula activation during anticipation of food images in women recovered from anorexia nervosa versus controls

Individuals with anorexia nervosa (AN) restrict food consumption and become severely emaciated. Eating food, even thinking of eating food, is often associated with heightened anxiety. However, food cue anticipation in AN is poorly understood. Fourteen women recovered from AN and 12 matched healthy control women performed an anticipation task viewing images of food and object images during functional magnetic resonance imaging. Comparing anticipation of food versus object images between control women and recovered AN groups showed significant interaction only in the right ventral anterior insula, with greater activation in recovered AN anticipating food images. These data support the hypothesis of a disconnect between anticipating and experiencing food stimuli in recovered AN. Insula activation positively correlated with pleasantness ratings of palatable foods in control women, while no such relationship existed in recovered AN, which is further evidence of altered interoceptive function. Finally, these findings raise the possibility that enhanced anterior insula anticipatory response to food cues in recovered AN could contribute to exaggerated sensitivity and anxiety related to food and eating.

Pulmonary rehabilitation has been shown to be of benefit to clinically stable patients with chronic obstructive pulmonary disease (COPD). This study examined the effect of pulmonary rehabilitation on some physiologic variables in COPD patients recovering from an episode of acute respiratory failure. A prospective, randomized study. A respiratory intensive care unit (RICU). Eighty COPD patients recovering from an episode of acute respiratory failure were randomized in a 3:1 fashion to receive stepwise pulmonary rehabilitation (group A, n=60 patients) or standard medical therapy (group B, n=20 patients). Improvements in exercise tolerance, sense of breathlessness, respiratory muscle function, and pulmonary function test values were measured, respectively, by exercise capacity (6-minute walking distance [6MWD]), dyspnea score (Visual Analog Scale [VAS]), maximal inspiratory pressure (MIP), forced expiratory volume in 1 second (FEV1), and forced vital capacity (FVC). Group A received pulmonary rehabilitation that consisted of passive mobilization (step I), early deambulation (step II), respiratory and lower skeletal muscle training (step III), and if the patients were able, complete lower extremity training on a treadmill (step IV). Group B received standard medical therapy plus a basic deambulation program. Sixty-one of 80 patients were mechanically ventilated at admission to the unit and most of them were bedridden. Twelve of the 60 group A patients and 4 of the 20 group B patients died during their RICU stay, and 9 patients required invasive mechanical ventilation at home after their discharge. The total length of RICU stay was 38+/-14 days for patients in group A versus 33.2+/-11 days for those in group B. Most patients from both groups regained the ability to walk, either unaided or aided. At discharge, 6 MWD results were significantly improved (p respiratory failure and who, in most cases, required mechanical ventilation benefited from comprehensive early

Cesium is recovered from cesium alum, CsAl(SO 4 ) 2 , by an aqueous conversion and precipitation reaction using a critical stoichiometric excess of a water-soluble permanganate to form solid cesium permanganate (CsMnO 4 ) free from cesium alum. The other metal salts remain in solution, providing the final pH does not cause hydroxides of aluminium or iron to form. The precipitate is separated from the residual solution to obtain CsMnO 4 of high purity

Full Text Available Abstract Background According to the UK Adult Dental Health Survey (2009 15% of adults aged 65–74, 30% aged 75–84 and 47% aged >85 years are edentulous and require complete dentures. Patients’ quality of life and nutrition status are affected by poor dentures. The quality of the dental impression is the most important issue for improving the fit and comfort of new dentures. There is paucity of RCT evidence for which impression material is best for complete dentures construction. This study aims to compare two impression materials for effectiveness and cost effectiveness. Methods/Design IMPROVDENT is a double-blind crossover trial comparing the use of alginate and silicone, two commonly used denture impression materials, in terms of patient preference and cost-effectiveness. Eighty five edentulous patients will be recruited and provided with two sets of dentures, similar in all aspects except for the impression material used (alginate or silicone. Patients will try both sets of dentures for a two-week period, unadjusted, to become accustomed to the feel of the new dentures (habituation period. Patients will then wear each set of dentures for a period of 8 weeks (in random order during which time the dentures will be adjusted for optimum comfort. Finally, patients will be given both sets of dentures for a further two weeks to wear whichever denture they prefer (confirmation period. Patients will be asked about quality of life and to rate dentures on function and comfort at the end of each trial period and asked which set they prefer at the end of the habituation period (unadjusted denture preference and confirmation period (adjusted denture preference. A health economic evaluation will estimate incremental cost-effectiveness ratios of producing dentures from the two materials. A qualitative study will investigate the impact of dentures on behaviour and quality of life. Funding: IMPROVDENT is funded by NIHR RfPB (PB-PG-0408-16300. Discussion

2011-01-01

Appropriate supportive care is essential for intensive chemoradiation therapy (CRT), and pain management is an important supportive care for CRT for head and neck cancer. We developed an opioid-based pain control program for head and neck cancer patients undergoing CRT, and assessed its efficacy and safety. 110 head and neck cancer patients undergoing platinum-based concomitant CRT were enrolled from 10 cancer centers or university hospitals. Their pain caused by CRT was managed with a four-step opioid-based pain control program, and adverse events and usage of opioid were analyzed. 101 suitable cases of 110 patients were analyzed. 53% of cases suffered grade 3-4 mucositis. The rate of completion of radiotherapy was 99% and the rate of unplanned breaks in radiotherapy was 13%. The usage rate of opioid was 83% and the rate of compliance with the pain control program was 92%. The median maximum quantity of morphine used per day was 35 mg. No patient had to stop the opioid program or radiotherapy due to adverse effects of opioids. An opioid-based pain control program for head and neck cancer patients undergoing CRT achieves a high completion rate of radiation. (author)

In the previous chapters was exposed the saga of German scientists that worked for Soviet scientists from 1945 to 1961 and allowed these ones to make up for the delay in a record time they had on the American people. However, without the help of German scientists, that were at exceptional level they would succeed regardless but they would take the same time than the others ones to reach the same result. To be complete, one should, in this fourth chapter, precise how the Soviet people succeeded to recover the uranium from the nazi nuclear programme. (N.C.)

A 65-year-old Chinese male was referred to our hospital for epidermal growth factor receptor (EGFR)-mutated advanced non-small cell lung cancer (NSCLC). Aggressive combined therapy with surgical resection of the right upper lung lesion and chemotherapy was performed. One month later, continued Icotinib treatment was used as magnetic resonance imaging revealed liver metastasis (LM). Interestingly, complete remission of the patient's LM lesions was achieved in six months. To our knowledge, this is the first report documenting a successful case of an NSCLC patient with LM treated with Icotinib after receiving a radical resection for pulmonary carcinoma. Our experience could provide a treatment strategy for patients with similar disease. © 2016 The Authors. Thoracic Cancer published by China Lung Oncology Group and John Wiley & Sons Australia, Ltd.

Changes in adaptive immune cells after chemotherapy in adult acute myeloid leukemia (AML) may have implications for the success of immunotherapy. This study was designed to determine the functional capacity of the immune system in adult patients with AML who have completed chemotherapy and are potential candidates for immunotherapy. We used the response to seasonal influenza vaccination as a surrogate for the robustness of the immune system in 10 AML patients in a complete remission post-chemotherapy and performed genetic, phenotypic, and functional characterization of adaptive immune cell subsets. Only 2 patients generated protective titers in response to vaccination, and a majority of patients had abnormal frequencies of transitional and memory B-cells. B-cell receptor sequencing showed a B-cell repertoire with little evidence of somatic hypermutation in most patients. Conversely, frequencies of T-cell populations were similar to those seen in healthy controls, and cytotoxic T-cells demonstrated antigen-specific activity after vaccination. Effector T-cells had increased PD-1 expression in AML patients least removed from chemotherapy. Our results suggest that while some aspects of cellular immunity recover quickly, humoral immunity is incompletely reconstituted in the year following intensive cytotoxic chemotherapy for AML. The observed B-cell abnormalities may explain the poor response to vaccination often seen in AML patients after chemotherapy. Furthermore, the uncoupled recovery of B-cell and T-cell immunity and increased PD-1 expression shortly after chemotherapy might have implications for the success of several modalities of immunotherapy.

Cauda equina syndrome after spinal anaesthesia in a patient with asymptomatic tubercular arachnoiditis

Full Text Available A 14-year-old boy underwent emergency debridement surgery of right foot under spinal anaesthesia. Four hours after the surgery, the patient developed symptoms of cauda equina syndrome (CES. Postoperative magnetic resonance imaging of the patient′s spine suggested underlying tubercular arachnoiditis. The boy was started on intravenous methylprednisolone and antitubercular therapy. He responded to the therapy and recovered completely in 2 weeks without any residual neurological deficits. We suggest that underlying pathological changes in the subarachnoid space due to tubercular arachnoiditis contributed to maldistribution of the local anaesthetic drug leading to CES.

Full Text Available Abstract Background Geminiviruses are a large and important family of plant viruses that infect a wide range of crops throughout the world. The Begomovirus genus contains species that are transmitted by whiteflies and are distributed worldwide causing disease on an array of horticultural crops. Symptom remission, in which newly developed leaves of systemically infected plants exhibit a reduction in symptom severity (recovery, has been observed on pepper (Capsicum annuum plants infected with Pepper golden mosaic virus (PepGMV. Previous studies have shown that transcriptional and post-transcriptional gene silencing mechanisms are involved in the reduction of viral nucleic acid concentration in recovered tissue. In this study, we employed deep transcriptome sequencing methods to assess transcriptional variation in healthy (mock, symptomatic, and recovered pepper leaves following PepGMV infection. Results Differential expression analyses of the pepper leaf transcriptome from symptomatic and recovered stages revealed a total of 309 differentially expressed genes between healthy (mock and symptomatic or recovered tissues. Computational prediction of differential expression was validated using quantitative reverse-transcription PCR confirming the robustness of our bioinformatic methods. Within the set of differentially expressed genes associated with the recovery process were genes involved in defense responses including pathogenesis-related proteins, reactive oxygen species, systemic acquired resistance, jasmonic acid biosynthesis, and ethylene signaling. No major differences were found when compared the differentially expressed genes in symptomatic and recovered tissues. On the other hand, a set of genes with novel roles in defense responses was identified including genes involved in histone modification. This latter result suggested that post-transcriptional and transcriptional gene silencing may be one of the major mechanisms involved in the

Quality standards and requirements for solid recovered fuels: a review.

Science.gov (United States)

Flamme, Sabine; Geiping, Julia

2012-04-01

The utilization of solid recovered fuels (SRF) for energy recovery has been increasing steadily in recent years, and this development is set to continue. In order to use SRF efficiently, it is necessary to define quality standards and introduce targeted quality assurance measures. SRF can be used both in mono-incineration and in co-incineration systems, for instance in power generation and cement plants; but as quality requirements differ, it is necessary to unambiguously define the term 'solid recovered fuel'. The purpose of this article is to provide an overview of the origin, development and the current status of quality assurance for SRF. The basic principles of quality assurance for SRF are explained with reference to the development of the German RAL Quality Assurance System and in addition specifications that have emerged from European standardization work of CEN/TC 343 are analysed.

Genome diversity of marine phages recovered from Mediterranean metagenomes: Size matters.

Directory of Open Access Journals (Sweden)

Mario López-Pérez

2017-09-01

Full Text Available Marine viruses play a critical role not only in the global geochemical cycles but also in the biology and evolution of their hosts. Despite their importance, viral diversity remains underexplored mostly due to sampling and cultivation challenges. Direct sequencing approaches such as viromics has provided new insights into the marine viral world. As a complementary approach, we analysed 24 microbial metagenomes (>0.2 μm size range obtained from six sites in the Mediterranean Sea that vary by depth, season and filter used to retrieve the fraction. Filter-size comparison showed a significant number of viral sequences that were retained on the larger-pore filters and were different from those found in the viral fraction from the same sample, indicating that some important viral information is missing using only assembly from viromes. Besides, we were able to describe 1,323 viral genomic fragments that were more than 10Kb in length, of which 36 represented complete viral genomes including some of them retrieved from a cross-assembly from different metagenomes. Host prediction based on sequence methods revealed new phage groups belonging to marine prokaryotes like SAR11, Cyanobacteria or SAR116. We also identified the first complete virophage from deep seawater and a new endemic clade of the recently discovered Marine group II Euryarchaeota virus. Furthermore, analysis of viral distribution using metagenomes and viromes indicated that most of the new phages were found exclusively in the Mediterranean Sea and some of them, mostly the ones recovered from deep metagenomes, do not recruit in any database probably indicating higher variability and endemicity in Mediterranean bathypelagic waters. Together these data provide the first detailed picture of genomic diversity, spatial and depth variations of viral communities within the Mediterranean Sea using metagenome assembly.

Bodies recovered from wells, sewerage systems and pits: what is the cause of death?

The aim of this study was to determine the problems encountered during investigations into causes of death in corpses found in wells, sewer systems and pits, and to seek solutions to the problems. In fact, wells, sewer systems and pits have some common characteristics which may cause the problems. They contain water, have a hypoxic/anoxic environment and prevent corpses from being recognised. Based on the data obtained from the 1st Specialization Board of the Council of Forensic Medicine, affiliated with the Ministry of Justice, we retrospectively reviewed 69 corpses found in wells, sewer systems and pits between 1 January 1992 and 31 December 2002. Data on age, sex, crime scene and causes of death were obtained and evaluated using the SPSS 11.0 package programme. Of 69 cases, 69.1% were male and 33.4% were aged 0 to 10 years. Fifty-eight per cent and 13.1% of the cases were found in wells and sewer systems respectively. Forty-three (62.3%) cases were found in a place with water. However, 34.9% of them had not drowned. The most frequent cause of death was drowning (40.6%). The cause of death was unknown in 18.8% of the cases. 15.9% of the corpses were exhumed to determine the cause of death. Twenty-six cases (37.7%) had signs of putrefaction and the cause of death was not determined in 9 cases. Diatom was investigated in 42.0% of the cases (29 cases), but 17 cases did not have diatom. It is a complicated process to determine the causes of death in bodies recovered from wells, pits, water supplies and sewer systems, etc. Thorough forensic investigations are required because death may result from a wide variety of factors, and lesions on the corpses may undergo some changes quickly or can be covered in wells, pits and water supplies. A complete crime scene investigation, a thorough autopsy and histopathological, toxicological and biochemical examinations would prevent potential problems in determining the causes of death in bodies recovered from wells, sewer systems

Retrospective single-center studies have shown that diffusion-weighted magnetic resonance imaging (DWI) is promising for identification of patients with rectal cancer with a complete tumor response after neoadjuvant chemoradiotherapy (CRT), using certain volumetric thresholds. This study aims to validate the diagnostic value of these volume thresholds in a larger, independent, and bi-institutional patient cohort. A total of 112 patients with locally advanced rectal cancer (2 centers) treated with a long course of CRT were enrolled. Patients underwent standard T2W-magnetic resonance imaging and DWI, both pre- and post-CRT. Two experienced readers independently determined pre-CRT and post-CRT tumor volumes (cm) on T2W-magnetic resonance image and diffusion-weighted magnetic resonance image by means of freehand tumor delineation. Tumor volume reduction rates (Δvolume) were calculated. Previously determined T2W and DWI threshold values for prevolume, postvolume, and Δvolume were tested to "prospectively" assess their respective diagnostic value in discriminating patients with a complete tumor response from patients with residual tumor. Twenty patients had a complete response. Using the average measurements between the 2 readers, areas under the curve for the pre-/post-/Δvolumes was 0.73/0.82/0.78 for T2W-magnetic resonance imaging and 0.77/0.92/0.86 for DWI, respectively. For T2W-volumetry, sensitivity and specificity using the predefined volume thresholds were 55% and 74% for pre-, 60% and 89% for post-, and 60% and 86% for Δvolume. For DWI volumetry, sensitivity and specificity were 65% and 76% for pre-, 70% and 98% for post-, and 70% and 93% for Δvolume. Previously established DWI volume thresholds can be reproduced with good results. Post-CRT DWI volumetry offers the best results for the detection of patients with a complete response after CRT with an area under the curve of 0.92, sensitivity of 70%, and specificity of 98%.

Stroke is the leading cause of death and disability in rural China. For stroke patients residing in resource-limited rural areas, secondary prevention and rehabilitation are largely unavailable, and where present, are far below evidence-based standards. This study aims to develop and implement a simplified stroke rehabilitation program that utilizes nurses and family caregivers for service delivery, and evaluate its feasibility and effectiveness in rural China. This 2-year randomized controlled trial is being conducted in 2-3 county hospitals located in northwest, northeast, and southwest China. Eligible and consenting stroke inpatients (200 in total) have been recruited and randomized into either a control or intervention group. Nurses in the county hospital are trained by rehabilitation specialists and in turn train the family caregivers in the intervention group. They also provide telephone follow-up care three times post discharge. The recruitment, baseline, intervention, follow-up care, and evaluation are guided by the RECOVER mobile phone app specifically designed for this study. The primary outcome is patients' Barthel Index (activities of daily living: mobility, self-care, and toileting) at 6 months. Process and economic evaluation will also be conducted. The results of our study will generate initial high-quality evidence to improve stroke care in resource-scarce settings. If proven effective, this innovative care delivery model has the potential to improve the health and function of stroke patients, relieve caregiver burden, guide policy-making, and advance translational research in the field of stroke care. © 2016 World Stroke Organization.

Purpose: Although the potential benefits of radiation therapy and chemotherapy in the management of completely resected AJCC N1 non-small cell lung cancer are unknown, the majority of studies have failed to demonstrate a survival benefit with any neoadjuvant or adjuvant therapy. While it is possible that radiation therapy and chemotherapy are ineffective adjunctive therapies in this disease, it is also possible that previous studies have been diluted by the inclusion of patients at low risk for local recurrence and/or distant metastasis and therefore, this study was undertaken to assess these risks. Methods: From 1987 through 1990, 107 patients underwent complete resection of AJCC N1 non-small cell lung carcinoma and received no other treatment. These patients were the subject of a retrospective review to separate patients into high-, medium-, and low-risk groups with respect to freedom from local recurrence (FFLR), freedom from distant metastasis (FFDM), and overall survival (OS) utilizing a regression analysis of Cox and a regression tree analysis (Breiman LI et al, Wadsworth International Group, Belmont, CA 1984). Results: The 5-year rates of FFLR, FFDM, and OS were 62%, 53%, and 32% respectively. The following factors were assessed for potential relationships with FFLR, FFDM, and OS: status of the pre-operative bronchoscopy, type of surgery performed (segmentectomy/wedge resection vs. lobectomy vs. bilobectomy/pneumonectomy), number of involved N1 nodes, number of involved N1 stations, number of N1 nodes removed, number of N2 nodes removed, number of lung lobes involved, tumor grade, tumor histology (squamous vs non-squamous), AJCC T-stage, pathologic tumor size, and pathologic margin status. Regression analyses revealed that the factors independently associated with an improved outcome included a positive bronchoscopy (FFLR, p=.005), a greater number of N1 nodes dissected (FFDM, p=.02), and a lesser T-stage (OS, p=.01). Regression tree analyses were then

Aim To determine ocular, sudomotor, and vasomotor components of Horner’s syndrome resulting from complete unilateral intraoperative damage to the parasellar sympathetic fibers during cavernous sinus surgery. Methods Complete damage to the parasellar sympathetic fibers was found in four patients operated for central skull base lesions. Pupilometry, eyelid fissure measurement, Hertel’s exophthalmometry, starch iodine sweat test, and laser-Doppler perfusion assessment of bilaterally symmetrical forehead and cheek areas were performed. Results Pupil diameter was smaller and the eyelid fissure was >2 mm narrower on the affected side in all four patients. Exophthalmometry after the operation never revealed >1 mm difference. Anhydrosis was localized to the medial forehead in three and to the entire forehead in one patient. Average perfusion did not significantly differ between the affected and opposite side of the forehead or cheek. Conclusions The parasellar sympathetic fibers exclusively innervate the orbit and variably innervate the forehead sweat glands. No conclusion regarding their contribution to the facial vasomotor control could be established. PMID:16625695

Process for recovering cesium from pollucite

International Nuclear Information System (INIS)

Mein, P.G.

1985-01-01

Cesium is recovered from a cesium-bearing mineral such as pollucite by extraction with hydrochloric acid to obtain an extract of cesium chloride and other alkali metal and polyvalent metal chlorides. The iron and aluminum chlorides can be precipitated as the hydroxides and separated from the solution of the alkali metal chlorides to which is added potassium permanganate or other water-soluble permanganate to selectively precipitate cesium permanganate. The cesium precipitate is then separated from the residual solution containing the metal chlorides. The cesium permanganate, which is in a very pure form, can be converted to other cesium compounds by reaction with a reducing agent to obtain cesium carbonate and cesium delta manganese dioxide

Phytoremediation of 1,4-dioxane-containing recovered groundwater.

Ferro, Ari M; Kennedy, Jean; LaRue, James C

2013-01-01

The results of a pilot-scale phytoremediation study are reported in this paper. Small plots of trees established on a closed municipal waste landfill site were irrigated with recovered groundwater containing 1,4-dioxane (dioxane) and other volatile organic compounds (VOCs). The plots were managed to minimize the leaching of irrigation water, and leaching was quantified by the use of bromide tracer. Results indicated that the dioxane (2.5 microg/L) was effectively removed, probably via phytovolatilization, and that a full-scale phytoremediation system could be used. A system is now in place at the site in which the recovered groundwater can be treated using two different approaches. A physical treatment system (PTS) will be used during the winter months, and a 12 ha phytoremediation system (stands of coniferous trees) will be used during the growing season. The PTS removes VOCs using an air-stripper, and destroys dioxane using a photo-catalytic oxidation process. Treated water will be routed to the local sewer system. The phytoremediation system, located on the landfill, will be irrigated with effluent from the PTS air-stripper containing dioxane. Seasonal use of the phytoremediation system will reduce reliance on the photo-catalytic oxidation process that is extremely energy consumptive and expensive to operate.

2013-01-01

Full Text Available Chronic myeloid leukemia (CML with the rare fusion gene e19a2, encoding a p230 protein, has been described in patients with typical or rather aggressive clinical course. Although tyrosine kinase inhibitors (TKIs induce a substantial cytogenetic and molecular response in all phases of CML, a minority of p230 positive patients have been treated with TKIs. We report two cases of CML patients carrying the p230 transcript, who achieved fast and deep complete molecular response (CMR after frontline treatment with nilotinib. Our results suggest the use of nilotinib as frontline agent for the treatment of this CML variant.

Presently, no studies have evaluated clinical outcomes or patient-centered outcomes for complete dentures fabricated with computer-aided design and computer aided manufacturing (CAD/CAM) technology. The purpose of this prospective cohort pilot study was to evaluate the clinical and patient-centered outcomes for CAD/CAM monolithic dentures fabricated in 2 visits. Twenty participants with an existing set of maxillary complete dentures opposing either mandibular complete dentures or implant-retained overdentures that required replacement were recruited in this study. A 2-visit duplicate denture protocol was used to fabricate 40 arches of monolithic dentures with CAD/CAM technology. A 100-mm visual analog scale (VAS) instrument was then used to record 12 outcomes at baseline and at 1-year follow-up. Predetermined values were assigned to grade the VAS rating of each outcome as favorable (70.1-100) and unfavorable (≤70). Favorable ratings were sub-divided as excellent (90.1-100), good (80.1-90), and fair (70.1-80). The clinical outcomes were evaluated independently by 2 experienced prosthodontists at baseline and at 1-year follow-up. Patients evaluated the corresponding patient-centered outcomes during the same time intervals. Additional descriptive variables were also recorded. Each clinical and patient-centered outcome was summarized by medians and ranges. Differences in all ratings recorded at baseline and at 1 year were tested by 1-sided sign test (α=.05). Of 20 participants, 3 were lost to follow-up, and 3 were unsatisfied with the digital dentures and withdrew from the study. These 3 participants were considered treatment failures. Of the 14 remaining participants, 9 had implant-retained mandibular overdentures, and 5 had conventional mandibular complete dentures. For clinical outcomes, the 12 studied outcomes were favorably evaluated by the 2 prosthodontist judges at the 1-year follow-up. Evaluations showed minimal differences between baseline and 1 year. An

The purpose of this study was to document the relationship between a discoid lateral meniscus and a thickened Wrisberg ligament with a higher location on the medial femoral condyle. Between July 2002 and February 2006, 100 consecutive patients who had a complete lateral discoid meniscus and another 100 patients without a discoid lateral meniscus (control group) were included. Two radiologists retrospectively reviewed all of the magnetic resonance images, paying particular attention to the presence and thickness of the Wrisberg ligament and the location of the attachment of the Wrisberg ligament to the medial femoral condyle (types I, II, or III). We assumed that type I Wrisberg ligaments had a higher location. All 141 patients had a Wrisberg ligament (71%). There were 73 patients (73%) in the discoid group and 68 patients (68%) in the non-discoid group. The mean thickness of the Wrisberg ligament in the patients in the discoid and non-discoid groups was 2.1 mm (range, 0.4-4.7 mm; median, 2.1 mm) and 1.6 mm (range, 0.4-4.5 mm; median, 1.3 mm), respectively. The Wrisberg ligaments of the discoid group were thicker than the non-discoid group (p=0.0002). The Wrisberg ligament was attached to the upper part of the medial femoral condyle in the discoid group more often than in the non-discoid group (p<0.0001). (orig.)

Complete genome sequence, lifestyle, and multi-drug resistance of the human pathogen Corynebacterium resistens DSM 45100 isolated from blood samples of a leukemia patient

Science.gov (United States)

2012-01-01

Background Corynebacterium resistens was initially recovered from human infections and recognized as a new coryneform species that is highly resistant to antimicrobial agents. Bacteremia associated with this organism in immunocompromised patients was rapidly fatal as standard minocycline therapies failed. C. resistens DSM 45100 was isolated from a blood culture of samples taken from a patient with acute myelocytic leukemia. The complete genome sequence of C. resistens DSM 45100 was determined by pyrosequencing to identify genes contributing to multi-drug resistance, virulence, and the lipophilic lifestyle of this newly described human pathogen. Results The genome of C. resistens DSM 45100 consists of a circular chromosome of 2,601,311 bp in size and the 28,312-bp plasmid pJA144188. Metabolic analysis showed that the genome of C. resistens DSM 45100 lacks genes for typical sugar uptake systems, anaplerotic functions, and a fatty acid synthase, explaining the strict lipophilic lifestyle of this species. The genome encodes a broad spectrum of enzymes ensuring the availability of exogenous fatty acids for growth, including predicted virulence factors that probably contribute to fatty acid metabolism by damaging host tissue. C. resistens DSM 45100 is able to use external L-histidine as a combined carbon and nitrogen source, presumably as a result of adaptation to the hitherto unknown habitat on the human skin. Plasmid pJA144188 harbors several genes contributing to antibiotic resistance of C. resistens DSM 45100, including a tetracycline resistance region of the Tet W type known from Lactobacillus reuteri and Streptococcus suis. The tet(W) gene of pJA144188 was cloned in Corynebacterium glutamicum and was shown to confer high levels of resistance to tetracycline, doxycycline, and minocycline in vitro. Conclusions The detected gene repertoire of C. resistens DSM 45100 provides insights into the lipophilic lifestyle and virulence functions of this newly recognized

Evaluation of data completeness in the electronic health record for the purpose of patient recruitment into clinical trials: a retrospective analysis of element presence

Science.gov (United States)

2013-01-01

Background Computerized clinical trial recruitment support is one promising field for the application of routine care data for clinical research. The primary task here is to compare the eligibility criteria defined in trial protocols with patient data contained in the electronic health record (EHR). To avoid the implementation of different patient definitions in multi-site trials, all participating research sites should use similar patient data from the EHR. Knowledge of the EHR data elements which are commonly available from most EHRs is required to be able to define a common set of criteria. The objective of this research is to determine for five tertiary care providers the extent of available data compared with the eligibility criteria of randomly selected clinical trials. Methods Each participating study site selected three clinical trials at random. All eligibility criteria sentences were broken up into independent patient characteristics, which were then assigned to one of the 27 semantic categories for eligibility criteria developed by Luo et al. We report on the fraction of patient characteristics with corresponding structured data elements in the EHR and on the fraction of patients with available data for these elements. The completeness of EHR data for the purpose of patient recruitment is calculated for each semantic group. Results 351 eligibility criteria from 15 clinical trials contained 706 patient characteristics. In average, 55% of these characteristics could be documented in the EHR. Clinical data was available for 64% of all patients, if corresponding data elements were available. The total completeness of EHR data for recruitment purposes is 35%. The best performing semantic groups were ‘age’ (89%), ‘gender’ (89%), ‘addictive behaviour’ (74%), ‘disease, symptom and sign’ (64%) and ‘organ or tissue status’ (61%). No data was available for 6 semantic groups. Conclusions There exists a significant gap in structure and content

Recovering uranium from phosphoric acid

International Nuclear Information System (INIS)

Anon.

1979-01-01

Wet-process phosphoric acid contains a significant amount of uranium. This uranium totals more than 1,500 tons/yr in current U.S. acid output--and projections put the uranium level at 8,000 tons/yr in the year 2000. Since the phosphoric acid is a major raw material for fertilizers, uranium finds its way into those products and is effectively lost as a resource, while adding to the amount of radioactive material that can contaminate the food chain. So, resource-conservation and environmental considerations both make recovery of the uranium from phosphoric acid desirable. This paper describes the newly developed process for recovering uranium from phosphoric acid by using solvent-extraction technique. After many extractants had been tested, the researchers eventually selected the combination of di (2-ethylhexyl) phosphoric acid (DEPA) and trioctylphosphine oxide (TOPO) as the most suitable. The flowscheme of the process is included

Full Text Available In patients presenting with complete atrioventricular (AV block, the common causes are degeneration of the conduction system, acute myocardial infarction, congenital and metabolic disorders (such as azotemia. However, at times, no cause can be ascribed and the label congenital or degenerative is applied depending on the patient's age and the QRS complex width. We present two cases of patients with complete AV block, who were subsequently found to have rare etiologies – sarcoidosis (with isolated feature of AV block and non-Hodgkin's lymphoma.

The aim was to characterise acute coronary syndrome patients with complete atrioventricular block and to assess the effect on outcome. Patients admitted with acute coronary syndrome were divided according to the presence of complete atrioventricular block: group 1, with complete atrioventricular block; group 2, without complete atrioventricular block. Clinical, electrocardiographic and echocardiographic characteristics and prognosis during one year follow-up were compared between the groups. Among 4799 acute coronary syndrome patients admitted during the study period, 91 (1.9%) presented with complete atrioventricular block. At presentation, group 1 patients presented with lower systolic blood pressure, higher Killip class and incidence of syncope. In group 1, 86.8% presented with ST-segment elevation myocardial infarction (STEMI), and inferior STEMI was verified in 79.1% of patients in group 1 compared with 21.9% in group 2 ( Pblock was observed in 7.3% in contrast to 2.5% in patients submitted to primary percutaneous coronary intervention ( Pblock was an independent predictor of hospital mortality (odds ratio 3.671; P=0.045). There was no significant difference in mortality at one-year follow-up between the study groups. Complete atrioventricular block conferred a worse outcome during hospitalisation, including a higher incidence of cardiogenic shock, ventricular arrhythmias and death.

Neural Inductive Matrix Completion for Predicting Disease-Gene Associations

KAUST Repository

Hou, Siqing

2018-05-21

In silico prioritization of undiscovered associations can help find causal genes of newly discovered diseases. Some existing methods are based on known associations, and side information of diseases and genes. We exploit the possibility of using a neural network model, Neural inductive matrix completion (NIMC), in disease-gene prediction. Comparing to the state-of-the-art inductive matrix completion method, using neural networks allows us to learn latent features from non-linear functions of input features. Previous methods use disease features only from mining text. Comparing to text mining, disease ontology is a more informative way of discovering correlation of dis- eases, from which we can calculate the similarities between diseases and help increase the performance of predicting disease-gene associations. We compare the proposed method with other state-of-the-art methods for pre- dicting associated genes for diseases from the Online Mendelian Inheritance in Man (OMIM) database. Results show that both new features and the proposed NIMC model can improve the chance of recovering an unknown associated gene in the top 100 predicted genes. Best results are obtained by using both the new features and the new model. Results also show the proposed method does better in predicting associated genes for newly discovered diseases.

Physical Function CAT scores in musculoskeletal patients were normally distributed like the distribution calibration population; however, the score distribution of the Depression CAT in musculoskeletal patients was nonnormal with a spike in the floor score. After excluding the floor spike, the distribution of the Depression CAT scores was not different from the population control group. Patients who scored the floor score on the Depression CAT took slightly less time per question for Physical Function CAT when compared with other musculoskeletal patients (floor patients: 11 ± 9 seconds; normally distributed patients: 12 ± 10 seconds; mean difference: 1 second [0.8-1.1]; p CAT (Floor Group: 4 ± 3 seconds; Standard Group: 7 ± 7 seconds; mean difference: 3 [2.9-3.2]; p CAT were younger than other patients (Floor Group: 50 ± 18 SD; Standard Group: 55 ± 16 SD; mean difference: 4.5 [4.2-4.7]; p CAT as part of routine practice, the Physical Function item bank had a normal performance, but there is a group of patients who hastily complete Depression questions producing a strong floor effect and calling into question the validity of those floor scores that indicate minimal depression.

We present a case in which chemoradiation therapy was effective in a geriatric patient with Stage IV anal canal cancer. The patient is an 81-year-old woman who complained of proctorrhagia and anal pain. She was referred to us by her family doctor who suspected rectal cancer. Tumors as large as 6.5 cm in diameter mainly on the right side of the rectum as well as 2 palpable enlarged lymph nodes on the right inguinal area, were found during the initial physical examination. Squamous cell carcinoma was elevated to 16 ng/mL. A CT scan revealed that irregularly shaped masses as large as 7 cm in diameter were externally exposed on the right side of the rectum along with enlarged lymph nodes on the right inguinal area and metastasis at S7 lesion in the liver. Squamous cell carcinoma was diagnosed from biopsy results. Due to her age, the chemotherapy regimen was S-1+CDDP with radiation therapy and 4-port irradiation (50.4 Gy) of the primary tumor, interior of the pelvis, and inguinal lymph nodes. Partial response was observed upon completion of treatment, and complete response was obtained after 6 months. She is currently an outpatient taking S-1: 60 mg/day orally. There is no indication of cancer recurrence after 1 year and 3 months, and she continues to visit an outpatient clinic for regular follow-ups. These results demonstrate the effectiveness of chemoradiation therapy for geriatric patients with Stage IV anal canal cancer.

Atomoxetine is a well-established pharmacotherapy for adult ADHD. Long-term studies show incremental reductions in symptoms over time. However, clinical experience suggests that patients differ in their response patterns. From 13 Eli Lilly-sponsored studies, we pooled and analyzed data for adults with ADHD who completed atomoxetine treatment at long-term (24 weeks; n=1443) and/or short-term (12 weeks; n=2830) time-points, and had CAARS-Inv:SV total and CGI-S data up to or after these time-points and at Week 0 (i.e. at baseline, when patients first received atomoxetine). The goal was to identify and describe distinct trajectories of response to atomoxetine using hierarchical clustering methods and linear mixed modelling. Based on the homogeneity of changes in CAARS-Inv:SV total scores, 5 response clusters were identified for patients who completed long-term (24 weeks) treatment with atomoxetine, and 4 clusters were identified for patients who completed short-term (12 weeks) treatment. Four of the 5 long-term clusters (comprising 95% of completer patients) showed positive trajectories: 2 faster responding clusters (L1 and L2), and 2 more gradually responding clusters (L3 and L4). Responses (i.e.≥30% reduction in CAARS-Inv:SV total score, and CGI-S score≤3) were observed at 8 and 24 weeks in 80% and 95% of completers in Cluster L1, versus 5% and 48% in Cluster L4. While many adults with ADHD responded relatively rapidly to atomoxetine, others responded more gradually without a clear plateau at 24 weeks. Longer-term treatment may be associated with greater numbers of responders. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

Full Text Available Introduction: to report our experience with 41 patients treated by early endoscopic realignment of complete post-traumatic rupture urethra. Materials and Methods: The study includes patients presented to our institute, between May 2004 and April 2009, with post-traumatic complete posterior urethral disruption. Preoperative retrograde urethrography, voiding cystourethrography and abdominopelvic CT were performed to evaluate the urethral defect length, the bladder neck competence, the prostate position, and the extent of the pelvic hematoma. Within the first week after trauma, antegrade and retrograde urethroscopy were performed to identify both urethral ends and insert urethral catheter. Patients were followed up by pericatheter retrograde urethrogram monthly postoperatively till catheter removal on disappearance of extravasation. Retrograde urethrography, voiding cystourethrography and urethroscopy were performed 1 month after the removal of the catheter. Follow-up abdominal ultrasound and uroflowmetry monthly till 6 months, bimonthly till 1 year, and every 3 months thereafter were encouraged. Urinary continence and postoperative erectile dysfunction were assessed by direct patient interview. Results: Forty one patients in the age group 17-61 years (mean 37.9 were treated. Patients were followed up for 12-36 months (mean 17 months. Complete healing of the urethra occurred in 18 patients (43.9%. Passable urethral stricture developed in 15 patients (36.6%. Complete urethral obstruction occurred in eight patients (19.5%. Conclusions: Early endoscopic realignment for complete posterior urethral rupture is a feasible technique with no or minimal intraoperative complications. The technique is successful as the definitive line of therapy in reasonable number of patients and seems to render further future interventions for inevitable urethral stricture easier.

Process for recovering tritium from molten lithium metal

Science.gov (United States)

Maroni, Victor A.

1976-01-01

Lithium tritide (LiT) is extracted from molten lithium metal that has been exposed to neutron irradiation for breeding tritium within a thermonuclear or fission reactor. The extraction is performed by intimately contacting the molten lithium metal with a molten lithium salt, for instance, lithium chloride - potassium chloride eutectic to distribute LiT between the salt and metal phases. The extracted tritium is recovered in gaseous form from the molten salt phase by a subsequent electrolytic or oxidation step.

Young people recovering from cancer may lack adequate support post-treatment, yet little is known about the types of support and information young Australians and their families need. This study investigated adolescent/young adult cancer survivors' and their families' perceptions of care and support needs after completing cancer treatment. Seventy semi-structured interviews were conducted with 19 survivors (mean age 16.1 years), 21 mothers, 15 fathers and 15 siblings. Interviews were recorded, transcribed and analysed using the conceptual framework of Miles and Huberman. Post-treatment, participants regarded medical staff positively but were reluctant to ask for their help fearing it may deflect resources away from patients still receiving treatment. Appraisals of social workers' and psychologists' support post-treatment were mixed. Formal emotional support was rarely accessed and participants reported that any additional funds should be directed to greater psychological support in this period. Participants also reported the need for additional financial support post-treatment. Clinicians need to be aware that while young people and their families may not demand support post-treatment, they may 'suffer in silence' or burden family members and friends with the responsibility of providing emotional support, though they may be experiencing distress also. © 2013 John Wiley & Sons Ltd.

Janassek, Patrick; Blumenstein, Sébastien; Elsäßer, Wolfgang

2018-02-15

By exploiting polarization correlations of light from a broadband fiber-based amplified spontaneous emission source we succeed in reconstructing a hidden polarization in a ghost polarimetry experiment in close analogy to ghost imaging and ghost spectroscopy. Thereby, an original linear polarization state in the object arm of a Mach-Zehnder interferometer configuration which has been camouflaged by a subsequent depolarizer is recovered by correlating it with light from a reference beam. The variation of a linear polarizer placed inside the reference beam results in a Malus law type second-order intensity correlation with high contrast, thus measuring a ghost polarigram.

To describe the contribution of forensic anthropology to the recovery, analysis, and identification of victims from the 1991-1995 war in Croatia recovered in wells. From 1996 to the present, human remains of a total of 61 individuals have been recovered from 13 wells. Six wells contained the remains of a single individual, one well contained the remains of 2 individuals, and 6 wells contained the remains 3 or more individuals. The majority of wells, containing 90.2% (55/61) of recovered individuals, were located within a 4 km radius of the Croatian-Serbian border. Forensic anthropologists re-individualized 26/61 (42.6%) individuals out of skeletonized and commingled remains, provided basic biological data on sex, age-at-death, and stature in all identifications (n=37), as well as established positive identification by recognizing unique skeletal features (antemortem fractures and skeletal evidence of antemortem surgical interventions) in 3/37 (8.1%) cases. Trauma analyses carried out by forensic anthropologists contributed to the determination of the cause of death in 38/61 (62.3%) individuals and to the probable cause of death in an additional 18/61 (29.5%) individuals. The most frequent (27/38, 71.0%) type of trauma causing death in individuals recovered from wells was a single gunshot wound. Forensic anthropologists, collaborating closely with forensic pathologists, forensic odontologists, forensic radiologists, criminologists, and molecular biologists contributed significantly to trauma analysis and identification of war victims recovered from wells.

Full Text Available It has been reported that many patients with lung metastasis of colorectal cancer (CRC underwent chemotherapy with fluorouracil, folinic acid, oxaliplatin, irinotecan, or capecitabine. There is a small number of reports about the capecitabine and irinotecan (XELIRI plus bevacizumab (BV therapy for patients with metastatic CRC in Japan. We report a case of successful BV+XELIRI therapy for rectal cancer with multiple lung metastases as first-line chemotherapy. A 53-year-old female presented with advanced rectal cancer and metastatic lung tumors. Following surgery, the patient was treated with XELIRI+BV. After 6 courses, a computed tomography scan showed complete response of the lung metastases. No recurrence has occurred for 3 years after chemotherapy was stopped.

A processes for recycling uranium that has been used for the production of molybdenum-99 involves irradiating a solution of uranium suitable for forming fission products including molybdenum-99, conditioning the irradiated solution to one suitable for inducing the formation of crystals of uranyl nitrate hydrates, then forming the crystals and a supernatant and then separating the crystals from the supernatant, thus using the crystals as a source of uranium for recycle. Molybdenum-99 is recovered from the supernatant using an adsorbent such as alumina. Another process involves irradiation of a solid target comprising uranium, forming an acidic solution from the irradiated target suitable for inducing the formation of crystals of uranyl nitrate hydrates, then forming the crystals and a supernatant and then separating the crystals from the supernatant, thus using the crystals as a source of uranium for recycle. Molybdenum-99 is recovered from the supernatant using an adsorbent such as alumina.

In Brazil, underreporting of mesothelioma and cancer of the pleura (MCP) is suspected to be high. Records from death certificates (SIM) and hospital registers (SIH-SUS) can be combined to recover missing data but only anonymous databases are available. This study shows how common data can be used for linkage and as an assessment of accuracy. Mesothelioma (all sites, ICD-10 codes C45.0-C45.9) and cancer of the pleura (C38.4) were retrieved from both information systems and combined using a linkage algorithm. Accuracy was examined with non-anonymous databases, limited to the state of São Paulo. We found 775 cases in death certificates and 283 in hospital registers. The linkage matched 57 cases, all accurately paired. Three cases, 0.4% in SIM and 1.3% in SIH-SUS, could not be matched because of data inconsistencies. A computer linkage can recover MCP cases from hospital records not found in death certificates in Brazil. © 2018 Wiley Periodicals, Inc.

Full Text Available Anorexia Nervosa (AN is a severe mental disorder characterized by food restriction and weight loss.This study aimed to test the model posed by Brooks et al. (2012, that women suffering from chronic AN show decreased food cue processing activity in brain regions associated with energy balance and food reward (bottom-up; BU and increased activity in brain regions associated with cognitive control (top-down; TD when compared to long term recovered AN (REC and healthy controls (HC. Three groups of women, 15 AN (mean illness duration 7.8 ± 4.1 y, 14 REC (mean duration of recovery 4.7 ± 2.7 yr and 15 HC viewed alternating blocks of food and non-food images preceded by a short instruction during functional magnetic resonance imaging (fMRI, after fasting overnight. Functional ROIs (fROIs were defined in BU (e.g. striatum, hippocampus, amygdala, hypothalamus and cerebellum, TD (e.g. medial and lateral prefrontal cortex, anterior cingulate, the insula and visual processing areas (VPA. Food-cue processing activation was extracted from all fROIs and compared between the groups. In addition, functional connectivity between the fROIs was examined by modular partitioning of the correlation matrix of all fROIs.We could not confirm the hypothesis that BU areas are activated to a lesser extent in AN upon visual processing of food images. Among the BU areas the caudate showed higher activation in both patient groups compared to HC. In accordance with Brooks et al.’s model, we did find evidence for increased TD control in AN and REC. The functional connectivity analysis yielded two clusters in HC and REC, but three clusters in AN. In HC fROIs across BU, TD and VPA areas clustered, in AN one cluster span across BU, TD and insula, one across BU, TD and VPA areas and one was confined to the VPA network. In REC BU, TD and VPA or VPA and insula clustered.In conclusion, despite weight recovery, neural processing of food cues is also altered in recovered AN patient

Lampreys recover locomotion spontaneously several weeks after a complete spinal cord injury. Dysfunction of the GABAergic system following SCI has been reported in mammalian models. So, it is of great interest to understand how the GABAergic system of lampreys adapts to the post-injury situation and how this relates to spontaneous recovery. The spinal cord of lampreys contains 3 populations of GABAergic neurons and most of the GABAergic innervation of the spinal cord comes from these local cells. GABAB receptors are expressed in the spinal cord of lampreys and they play important roles in the control of locomotion. The aims of the present study were to quantify: 1) the changes in the number of GABAergic neurons and innervation of the spinal cord and 2) the changes in the expression of the gabab receptor subunits b1 and b2 in the spinal cord of the sea lamprey after SCI. We performed complete spinal cord transections at the level of the fifth gill of mature larval lampreys and GABA immunohistochemistry or gabab in situ hybridization experiments. Animals were analysed up to 10 weeks post-lesion (wpl), when behavioural analyses showed that they recovered normal appearing locomotion (stage 6 in the Ayer's scale of locomotor recovery). We observed a significant decrease in the number of GABA-ir cells and fibres 1 h after lesion both rostral and caudal to the lesion site. GABA-ir cell numbers and innervation were recovered to control levels 1 to 2 wpl. At 1, 4 and 10 wpl the expression of gabab1 and gabab2 transcripts was significantly decreased in the spinal cord compared to control un-lesioned animals. This is the first study reporting the quantitative long-term changes in the number of GABAergic cells and fibres and in the expression of gabab receptors in the spinal cord of any vertebrate following a traumatic SCI. Our results show that in lampreys there is a full recovery of the GABAergic neurons and a decrease in the expression of gabab receptors when functional

Stereognosis has been defined as the appreciation of the form of objects by palpation. Whilst this definition holds good for the manual exploration of objects, it is possible for the shape of objects to be explored intra orally referred to as oral stereognosis. To better understand patients' relative satisfaction with complete dentures, differences in oral stereognostic perception, based on the identification of 6 edible objects was analyzed in a group of 30 edentulous individuals at 3 stages, namely, just before (pre-treatment), 30 min after (30 min post-treatment) and 1 month after (1 month post-treatment) the insertion of new dentures. The time required to identify each object was recorded and the correctness of identification of each object was scored using oral stereognostic score. Descriptive statistics, Wilcoxon signed rank test, Spearman's rank correlation test, Pearson Chi square test was used to statistically analyze the data obtained. OSA scores was significantly increased 1 month post-treatment compared to 30 min post-treatment (p < 0.05). It was found that Oral stereognostic test is reliable for measuring patients' oral stereognostic perception and may be used as one of the clinical aids in appreciating the functional limitations imposed by the prostheses.

Fixing Formalin: A Method to Recover Genomic-Scale DNA Sequence Data from Formalin-Fixed Museum Specimens Using High-Throughput Sequencing.

Full Text Available For 150 years or more, specimens were routinely collected and deposited in natural history collections without preserving fresh tissue samples for genetic analysis. In the case of most herpetological specimens (i.e. amphibians and reptiles, attempts to extract and sequence DNA from formalin-fixed, ethanol-preserved specimens-particularly for use in phylogenetic analyses-has been laborious and largely ineffective due to the highly fragmented nature of the DNA. As a result, tens of thousands of specimens in herpetological collections have not been available for sequence-based phylogenetic studies. Massively parallel High-Throughput Sequencing methods and the associated bioinformatics, however, are particularly suited to recovering meaningful genetic markers from severely degraded/fragmented DNA sequences such as DNA damaged by formalin-fixation. In this study, we compared previously published DNA extraction methods on three tissue types subsampled from formalin-fixed specimens of Anolis carolinensis, followed by sequencing. Sufficient quality DNA was recovered from liver tissue, making this technique minimally destructive to museum specimens. Sequencing was only successful for the more recently collected specimen (collected ~30 ybp. We suspect this could be due either to the conditions of preservation and/or the amount of tissue used for extraction purposes. For the successfully sequenced sample, we found a high rate of base misincorporation. After rigorous trimming, we successfully mapped 27.93% of the cleaned reads to the reference genome, were able to reconstruct the complete mitochondrial genome, and recovered an accurate phylogenetic placement for our specimen. We conclude that the amount of DNA available, which can vary depending on specimen age and preservation conditions, will determine if sequencing will be successful. The technique described here will greatly improve the value of museum collections by making many formalin-fixed specimens

The benefits of a minimally invasive approach to off-pump coronary artery bypass remain controversial. The value of completion arteriography in validating this technique has not been investigated. From April 2007 to October 2009, fifty-six patients underwent isolated minimally invasive coronary artery bypass grafting through a left thoracotomy without cardiopulmonary bypass. Forty-three of these patients underwent completion arteriography. Sixty-five grafts were performed in these 56 patients, (average, 1.2 grafts per patient; range, 1 to 3). Forty-eight grafts were studied in the 43 patients undergoing completion arteriography. There were 4 findings on arteriogram leading to further immediate intervention (8.3%). These included 3 grafts with anastomotic stenoses or spasm requiring stent placement, and 1 patient who had limited dissection in the left internal mammary artery graft and underwent placement of an additional vein graft. These findings were independent of electrocardiographic changes or hemodynamic instability. The remainder of the studies showed no significant abnormalities. There were no deaths. One patient who did not have a completion arteriogram suffered a postoperative myocardial infarction requiring stent placement for anastomotic stenosis. Patients were discharged home an average of 6.8 days postoperatively. There were no instances of renal dysfunction postoperatively attributable to catheterization. Minimally invasive coronary artery bypass is safe and effective. Findings of completion arteriography occasionally reveal previously under-recognized findings that, if corrected in a timely fashion, could potentially impact graft patency and clinical outcomes. Our experience validates this minimally invasive technique. Copyright © 2011 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

Hyperkalemia-induced complete heart block

Full Text Available Background: Potassium, as an extracellular ion, plays an important role in the electrophysiologic function of the myocardium and any change in extracellular concentration of this ion might have a marked impression upon myocyte electrophysiologic gain. High serum potassium levels are thought to impair pulse conduction in Purkinje fibers and ventricles more than that in the Atrioventricular (AV node. Therefore, although complete AV block can occur, it is a rare initial presentation. Case Report: We describe a 62-year-old man with a history of diabetes mellitus, ischemic heart disease and previous Coronary Artery Bypass Graft (CABG, who came to our emergency department due to generalized weakness starting 2 days before admission. The patient also had decreased force in lower limbs, exacerbating from the morning, and was finally diagnosed as a hyperkalemia-induced Complete Heart Block (CHB. It should also be noted that the patient responded dramatically to the administration of 10 mL of 10% calcium gluconate along with external pacing until potassium level correction became effective. Conclusion: In spite of the fact that Hyperkalemia can be associated with frequent Electrocardiogram (ECG abnormality, advanced heart blocks (second- and third-degree AV blocks are usually found only in patients with pre-existing heart failure, conduction abnormalities, or other cardiac diseases. Institution of effective treatment rapidly and forgiveness of traditional non-effective, time consumptive and sometimes risking full-adjustment modalities, such as sodium bicarbonate infusion or exchange resins that prevent their use in the emergent phase, can help minimize patient morbidity and mortality.

Between 1964 and 1978, NASA launched a series of seven Nimbus meteorological satellites which provided Earth observations for 30 years. These satellites, carrying a total of 33 instruments to observe the Earth at visible, infrared, ultraviolet, and microwave wavelengths, revolutionized weather forecasting, provided early observations of ocean color and atmospheric ozone, and prototyped location-based search and rescue capabilities. The Nimbus series paved the way for a number of currently operational systems such as the EOS Terra, Aqua and Aura platforms.The original data archive included both magnetic tapes and film media. These media are well past their expected end of life, placing at risk valuable data that are critical to extending the history of Earth observations back in time. GES DISC has been incorporating these data into a modern online archive by recovering the digital data files from the tapes, and scanning images of the data from film strips. The original data products were written on obsolete hardware systems in outdated file formats, and in the absence of metadata standards at that time, were often written in proprietary file structures. Through a tedious and laborious process, oft-corrupted data are recovered, and incomplete metadata and documentation are reconstructed.

Electrical impedance spectroscopy as a potential tool for recovering bone porosity

International Nuclear Information System (INIS)

Bonifasi-Lista, C; Cherkaev, E

2009-01-01

This paper deals with the recovery of porosity of bone from measurements of its effective electrical properties. The microstructural information is contained in the spectral measure in the Stieltjes representation of the bone effective complex permittivity or complex conductivity and can be recovered from the measurements over a range of frequencies. The problem of reconstruction of the spectral measure is very ill-posed and requires the use of regularization techniques. We apply the method to the effective electrical properties of cancellous bone numerically calculated using micro-CT images of human vertebrae. The presented method is based on an analytical approach and does not rely on correlation analysis nor on any a priori model of the bone micro-architecture. However the method requires a priori knowledge of the properties of the bone constituents (trabecular tissue and bone marrow). These properties vary from patient to patient. To address this issue, a sensitivity analysis of the technique was performed. Normally distributed random noise was added to the data to simulate uncertainty in the properties of the constituents and possible experimental errors in measurements of the effective properties. The values of porosity calculated from effective complex conductivity are in good agreement with the true values of bone porosity even assuming high level errors in the estimation of the bone components. These results prove the future potential of electrical impedance spectroscopy for in vivo monitoring of level and treatment of osteoporosis.

Surgical stabilization of injured spine in patients with complete spinal cord injury is a common practice despite the lack of strong evidence supporting it. The aim of this study is to compare clinical outcomes and cost-effectiveness of surgical stabilization versus conservative management of spinal injury in patients with complete deficits, essentially from a developing country's point of view. A detailed analysis of patients with traumatic spine injury and complete deficits admitted at the Aga Khan University Hospital, Pakistan, from January 2004 till January 2010 was carried out. All patients presenting within 14 days of injury were divided in two groups, those who underwent stabilization procedures and those who were managed non-operatively. The two groups were compared with the endpoints being time to rehabilitation, length of hospital stay, 30 day morbidity/mortality, cost of treatment, and status at follow up. Fifty-four patients fulfilled the inclusion criteria and half of these were operated. On comparing endpoints, patients in the operative group took longer time to rehabilitation (P-value = 0.002); had longer hospital stay (P-value = 0.006) which included longer length of stay in special care unit (P-value = 0.002) as well as intensive care unit (P-value = 0.004); and were associated with more complications, especially those related to infections (P-value = 0.002). The mean cost of treatment was also significantly higher in the operative group (USD 6,500) as compared to non-operative group (USD 1490) (P-value managed non-operatively with a provision of surgery only if their rehabilitation is impeded due to pain or deformity.

Balloon dilatation of nasolacrimal drainage apparatus was attempted for the treatment of stenoses or obstructures of the nasolacrimal system in 49 eyes of 41 consecutive patients with complete obstructions and 16 eyes of 14 patients with incomplete obstructions. These two groups were compared with regards to the effectiveness of balloon dacryocystoplasty. All patients suffered from severe epiphora had already undergone multiple probings. A 0.018 inch hair or ball guide wire was introduced through the superior punctum into the inferior meatus of the nasal cavity and pulled out through the nasal aperture using a hemostat under nasal endoscopy. A deflated angiography balloon catheter was then introduced in a retrograde direction and dilated under fluoroscopic control. No major complications occurred in any of the patients. At 7 days after balloon dilatation, 25 of 49 eyes with complete obstruction demonstrated improvement in epiphora (initial success rate: 51.0%) and among them 17 eyes showed complete resolution of symptoms. Reocclusion occurred in 12 of the 25 eyes with initial improvement at the 2 months follow up. For the 16 eyes with incomplete obstruction, and improvement of epiphora was attained in 11 eyes (initial success rate 68.8%): 5 of these eyes showed complete resolution of epiphora, and 3 was failed to maintain initial improvement at the 2 month follow up. Although this study demonstrate that results of balloon dacryocystoplasty are not encouraging because of the high failure and recurrence rate, balloon dacryocystoplasty is a simple and safe nonsurgical technique that can be used to treat for obstructions of the nasolacrimal system. In addition, balloon dacryocystoplasty shows better results in incomplete obstruction than in complete obstruction than complete obstruction of the nasolacrimal system

Chouliara, Z; Karatzias, T; Gullone, A

2014-02-01

Research on survivors' experiences of recovering from childhood sexual abuse (CSA) has been limited and focused on those with severe mental health difficulties. This study elicited experiences of recovery from CSA in male and female survivors who have/have not utilized mental health services. The tangible end-point was to propose a theoretical model of personally meaningful recovery. This is a qualitative study, which utilized semi-structured individual interviews following the critical incident technique. Transcripts were analysed using Interpretative Phenomenological Analysis to identify recurrent themes. A total 22 adult survivors of CSA. Main themes identified were: The Affected Self, Factors Hindering Recovery, Factors Enhancing Recovery, The Hurdles of Recovery and the Recovering Self. The affected self included: lack of boundary awareness and self-blame, over self-reliance, over-vigilance and guilt, shame, aloneness and social stigma. The recovering self was characterized by increasing confidence, assertiveness, ability to self-care and self-acceptance, and by embracing vulnerability. These findings have potentially major implications for clinical practice, service provision, policy development and professional training in this field. The importance of disclosure in the healing process seemed paramount and can have major implications for current service protocols. © 2013 John Wiley & Sons Ltd.

Codependents of Recovering Addicts: Exploring Their Level of Depression and Self-Esteem

Directory of Open Access Journals (Sweden)

AIMEE ROSE A. ARGUELLES – MANDA

2014-04-01

Full Text Available Addiction is a family disease. It causes members of a family to develop coping methods that help them interact with one another. This descriptive study explored the relationship between level of depression and self-esteem of 30 codependents of recovering addicts. Respondents are mostly in their midlife, married, and college graduate females who were spouses or wives of recovering addicts. Majority of them experience low levels of depression while only minimal are clinically depressed. As for self esteem, half of the respondents had moderately low levels while the other half had either mildly low or severely low levels. Results show there is no significant relationship between the level of depression and self esteem of codependents of recovering addicts and that depression doesn’t really equate into a low level of self esteem. This research recommends that a more in-depth research be done to explore more contributing factors on the level of selfesteem of Codependents including a comparative study on those who have dependents still in active addiction. Aside from this, institutions involved such as schools, counselors and rehabilitation centers educate families and children of codependents at a young age about addiction as a disease and use the findings of this study to come up with more supportive programs for the family

Synthesis of linear regression coefficients by recovering the within-study covariance matrix from summary statistics.

Science.gov (United States)

Yoneoka, Daisuke; Henmi, Masayuki

2017-06-01

Recently, the number of regression models has dramatically increased in several academic fields. However, within the context of meta-analysis, synthesis methods for such models have not been developed in a commensurate trend. One of the difficulties hindering the development is the disparity in sets of covariates among literature models. If the sets of covariates differ across models, interpretation of coefficients will differ, thereby making it difficult to synthesize them. Moreover, previous synthesis methods for regression models, such as multivariate meta-analysis, often have problems because covariance matrix of coefficients (i.e. within-study correlations) or individual patient data are not necessarily available. This study, therefore, proposes a brief explanation regarding a method to synthesize linear regression models under different covariate sets by using a generalized least squares method involving bias correction terms. Especially, we also propose an approach to recover (at most) threecorrelations of covariates, which is required for the calculation of the bias term without individual patient data.
