This research is an extension of earlier studies that examined Assertiveness and Aggressiveness as potential moderators of verbal intentions. A sample of 127 women and 137 men participated in the survey which used random residential telephone numbers. Respondents ranged in age from 18 to 71 years (M=33.2, SD= 12.4), with men making up 51.9% of the total sample. Those respondents classified as having an Aggressive interaction style were least likely to have discussed their unsatisfactory service encounters. The nature of the verbal communications was negative for all four interaction styles investigated. Similar to previous findings, men and women were equally Assertive, but men were more likely to be Aggressive when engaging in marketplace interactions.

Results of thyroid biopsy determine whether thyroid nodule resection is appropriate and the extent of thyroid surgery. At our institution we use 20/22-gauge core biopsy (CBx) in conjunction with fine-needle aspiration (FNA) to decrease the number of passes and improve adequacy. Occasionally, both ultrasound (US)-guided FNA and CBx yield unsatisfactory specimens. To justify clinical recommendations for these unsatisfactory thyroid biopsies, we compare rates of malignancy at surgical resection for unsatisfactory biopsy results against definitive biopsy results. We retrospectively reviewed a database of 1979 patients who had a total of 2677 FNA and 663 CBx performed by experienced interventional radiologists under US guidance from 2003 to 2006 at a tertiary-care academic center. In 451 patients who had surgery following biopsy, Fisher's exact test was used to compare surgical malignancy rates between unsatisfactory and malignant biopsy cohorts as well as between unsatisfactory and benign biopsy cohorts. We defined statistical significance at P = 0.05. We reported an overall unsatisfactory thyroid biopsy rate of 3.7% (100/2677). A statistically significant higher rate of surgically proven malignancies was found in malignant biopsy patients compared to unsatisfactory biopsy patients (P = 0.0001). The incidence of surgically proven malignancy in unsatisfactory biopsy patients was not significantly different from that in benign biopsy patients (P = 0.8625). In conclusion, an extremely low incidence of malignancy was associated with both benign and unsatisfactory thyroid biopsy results. The difference in incidence between these two groups was not statistically significant. Therefore, patients with unsatisfactory biopsy specimens can be reassured and counseled accordingly.

The Welsh Food Microbiological Forum "shopping basket" survey is a long running, structured surveillance program examining ready-to-eat food randomly sampled from the point of sale or service in Wales, United Kingdom. The annual unsatisfactory rates for selected indicators and pathogens for 1998 through 2008 were examined. All the annual unsatisfactory rates for the selected pathogens were <0.5%, and no pattern with the annual rate was observed. There was also no discernible trend observed for the annual rates of Listeria spp. (not moncytogenes), with all rates <0.5%. However, there was a trend observed for Esherichia coli, with a decrease in rate between 1998 and 2003, rapid in the first few years, and then a gradual increase in rate up to 2008. It was concluded that there was no discernible pattern to the annual unsatisfactory rates for Listeria spp. (not monocytogenes), L. monocytogenes, Staphylococcus aureus, and Bacillus cereus, but that a definite trend had been observed for E. coli.

BACKGROUND Some myopia patients with unsatisfactory corneas consider corneal refractive surgery for different reasons. Accelerated corneal collagen crosslinking (ACXL) is an effective method to enhance the resistance of the cornea. The present investigation was designed to evaluate the changes of biomechanical properties in patients with myopia and thin corneas after femtosecond-laser in situ keratomileusis (FS-LASIK) concurrent with ACXL. MATERIAL AND METHODS A prospective study was designed. A total of 22 eyes of 11 myopia astigmatism patients with unsatisfactory corneas were enrolled. The patients were assigned to femtosecond-laser in situ keratomileusis concurrent with accelerated corneal collagen crosslinking (FS-LASIK-ACXL). The follow-up duration was 24 months. Manifest refraction, uncorrected (UDVA), and corrected distance visual acuity (CDVA), ultra-high-speed camera (Corvis-ST), corneal topography, anterior segment OCT (AS-OCT), Pentacam, and endothelial cell density (ECD) were examined before and after the operation. The corneal biomechanical and refractive data was analyzed using SAS9.3. Data were analyzed through normal distribution test and variance of analysis. The difference was considered as statistically significant when pLASIK-ACXL operation. The values of first applanation length (A1L), the second applanation length (A2L), the first applanation velocity (A1V), the second applanation velocity (A2V), deformation amplitude (DA), highest concavity peak distance (PD), and radius of curvature at the time of highest concavity (HCR) did not show significant difference after the operation. CONCLUSIONS FS-LASIK-ACXL is an effective and safe surgery for improving visual acuity for myopic patients with thin corneas, and it does not increase the risk of iatrogenic keratectasia.

Facing the increasing prevalence of gestational diabetes mellitus (GDM), this study aimed to evaluate the management of GDM and its association with adverse pregnancy outcomes. The data of 996 inpatients with GDM who terminated pregnancies in our hospital from January 2011 to December 2015 were collected. Treatments during pregnancy and the last hospital admission before delivery were analyzed. Pregnancy outcomes of the GDM patients were compared with 996 nondiabetic subjects matched by delivery year and gestational age. The association between fasting plasma glucose (FPG) and adverse pregnancy outcomes was examined by logistic regression analyses. The average prevalence of GDM over the 5 years was 4.4% (1330/30,191). Within the GDM patients, 42.8% (426/996) received dietary intervention, whereas 19.1% (190/996) received insulin treatment. Adverse outcomes were more likely to occur in patients with unsatisfactory control of blood glucose such as respiratory distress syndrome (RDS, χ 2 = 13.373, P < 0.01). Elevated FPG was identified as an independent risk factor for premature birth (odds ratio [OR] = 1.460, P < 0.001), neonatal care unit admission (OR = 1.284, P < 0.001), RDS (OR = 1.322, P = 0.001), and stillbirth (OR = 1.427, P < 0.001). Management of GDM in the real world of clinical practice was unsatisfactory, which might have contributed to adverse pregnancy outcomes.

The purpose of the present study was to extend the external validity of an earlier longitudinal study of school leavers by including participants from a representative sample of secondary schools. Questionnaires were administered annually to a sample of South Australian school leavers over a 10-year period. At Time 1 participants were in the last compulsory year of high school aged around 15 years and at Time 10 they were aged around 25 years. Results confirmed those from an earlier longitudinal study showing that the transition from school to satisfactory employment was associated with significant improvements in psychological well-being, whereas transition from school to unemployment or unsatisfactory employment showed no change in psychological well-being. The current findings extended the external validity of the earlier study because whereas participants in the earlier study were sampled from co-educational metropolitan public high schools, the current study included participants from every kind of high school: single sex as well as co-educational, rural as well as metropolitan, and private as well as public.

Sauropterygians form the largest and most diverse group of ancient marine reptiles that lived throughout nearly the entire Mesozoic era (from 250 to 65 million years ago). Although thousands of specimens of this group have been collected around the world since the description of the first plesiosaur in 1821 (ref. 3), no direct evidence has been found to determine whether any sauropterygians came on shore to lay eggs (oviparity) like sea turtles, or gave birth in the water to live young (viviparity) as ichthyosaurs and mosasauroids (marine lizards) did. Viviparity has been proposed for plesiosaur, pachypleurosaur and nothosaur sauropterygians, but until now no concrete evidence has been advanced. Here we report two gravid specimens of Keichousaurus hui Young from the Middle Triassic of China. These exquisitely preserved specimens not only provide the first unequivocal evidence of reproductive mode and sexual dimorphism in sauropterygians, but also indicate that viviparity could have been expedited by the evolution of a movable pelvis in pachypleurosaurs. By extension, this has implications for the reproductive pattern of other sauropterygians and Mesozoic marine reptiles that possessed a movable pelvis.

Full Text Available Conjunctival injection and tearing with unilateral short lasting neuralgiform headache syndrome is called as SUNCT. Even though these headaches are reported seldomly, the prevalence is possibly higher than known. It is of importance to recognize these uncommon disorder, since its management differs from common primary headaches. Until today, it was reported to be treated with different types of drugs. We here reported a 30 years old male patient with normal neurological examination, blood examination and neuroimaging. Our patient gave no response to indomethacin, gabapentine and carbamazepine treatments. This case is an example of SUNCT case treated with steroid

Clinical signs of malnutrition, starvation, cachexia and sarcopenia overlap, as they all imply muscle wasting to a various extent. However, the underlying mechanisms differ fundamentally and therefore distinction between these phenomena has therapeutic and prognostic implications. We aimed to determine whether dietitians in selected European countries have 'sufficient knowledge' regarding malnutrition, starvation, cachexia and sarcopenia, and use these terms in their daily clinical work. An anonymous online survey was performed among dietitians in Belgium, the Netherlands, Norway and Sweden. 'Sufficient knowledge' was defined as having mentioned at least two of the three common domains of malnutrition according to ESPEN definition of malnutrition (2011): 'nutritional balance', 'body composition' and 'functionality and clinical outcome', and a correct answer to three cases on starvation, cachexia and sarcopenia. Chi-square test was used to analyse differences in experience, work place and number of malnourished patients treated between dietitians with 'sufficient knowledge' vs. 'less sufficient knowledge'. 712/7186 responded to the questionnaire, of which data of 369 dietitians were included in the analysis (5%). The term 'malnutrition' is being used in clinical practice by 88% of the respondents. Starvation, cachexia and sarcopenia is being used by 3%, 30% and 12% respectively. The cases on starvation, cachexia and sarcopenia were correctly identified by 58%, 43% and 74% respectively. 13% of the respondents had 'sufficient knowledge'. 31% of the respondents identified all cases correctly. The proportion of respondents with 'sufficient knowledge' was significantly higher in those working in a hospital or in municipality (16%, P four European countries show that the percentage of dietitians with 'sufficient knowledge' regarding malnutrition, starvation, cachexia and sarcopenia is unsatisfactory (13%). The terms starvation, cachexia and sarcopenia are not often used

Why do results conflict regarding the prognostic value of the methylation status in colon cancers? the role of the preservation method

Full Text Available Abstract Background In colorectal carcinoma, extensive gene promoter hypermethylation is called the CpG island methylator phenotype (CIMP. Explaining why studies on CIMP and survival yield conflicting results is essential. Most experiments to measure DNA methylation rely on the sodium bisulfite conversion of unmethylated cytosines into uracils. No study has evaluated the performance of bisulfite conversion and methylation levels from matched cryo-preserved and Formalin-Fixed Paraffin Embedded (FFPE samples using pyrosequencing. Methods Couples of matched cryo-preserved and FFPE samples from 40 colon adenocarcinomas were analyzed. Rates of bisulfite conversion and levels of methylation of LINE-1, MLH1 and MGMT markers were measured. Results For the reproducibility of bisulfite conversion, the mean of bisulfite-to-bisulfite standard deviation (SD was 1.3%. The mean of run-to-run SD of PCR/pyrosequencing was 0.9%. Of the 40 DNA couples, only 67.5%, 55.0%, and 57.5% of FFPE DNA were interpretable for LINE-1, MLH1, and MGMT markers, respectively, after the first analysis. On frozen samples the proportion of well converted samples was 95.0%, 97.4% and 87.2% respectively. For DNA showing a total bisulfite conversion, 8 couples (27.6% for LINE-1, 4 couples (15.4% for MLH1 and 8 couples (25.8% for MGMT displayed significant differences in methylation levels. Conclusions Frozen samples gave reproducible results for bisulfite conversion and reliable methylation levels. FFPE samples gave unsatisfactory and non reproducible bisulfite conversions leading to random results for methylation levels. The use of FFPE collections to assess DNA methylation by bisulfite methods must not be recommended. This can partly explain the conflicting results on the prognosis of CIMP colon cancers.

McCormick, R.D.

1983-01-01

This paper describes the results of analyses of nuclear fuel rod cladding temperature data obtained during in-reactor experiments under steady state and transient (simulated loss-of-coolant accident) operating conditions. The objective of the analyses was to determine the effect of thermocouple attachment method and location on measured thermal response. The use of external thermocouples increased the time to critical heat flux (CHF), reduced the blowdown peak temperature, and enhanced rod quench. A comparison of laser welded and resistance welded external thermocouple responses showed that the laser welding technique reduced the indicated cladding steady state temperatures and provided shorter time-to-CHF. A comparison of internal welded and embedded thermocouples indicated that the welded technique gave generally unsatisfactory cladding temperature measurements. The embedded thermocouple gave good, consistent results, but was possibly more fragile than the welded thermocouples. Detailed descriptions of the thermocouple designs, attachment methods and locations, and test conditions are provided

1987-01-01

The results obtained in four successive trials based on the analysis of urography performed on patients with normal kidney function are reported. The scores obtained with a non-ionic contrast (Iopamidol) were compared with those produced after injecting the same contrast medium with the addition of various diuretics (furosemide, various quantitives of 5% glucose solution, 20% mannitol). The results obtained by injecting the diuretic together with the Iopamidol were usually unsatisfactory. Injection of diuretic 15 ms after the Iopamidol gave better results in the lower urinary tract, particularly the bladder. The best results were obtained by injecting 250 ml, 20% mannitol, after 15 ms. However this technique is not applicable to patients requiring a voiding cystourethrogram due to the inadequate opacification of the urethra it provides

Femoral head and neck ostectomy (FHNO) is a salvage surgical procedure intended to eliminate hip joint laxity associated pain in the immature dog, or pain due to secondary osteoarthritis in the mature dog. The outcome of the procedure is associated with the size of the dog but the cause of a generally poorer outcome in larger breeds has not been determined. The objective of this study was to assess the long-term results of FHNO associated with unsatisfactory functional outcome by means of clinical examination and computed tomography (CT) scanning. Four large mixed breed dogs underwent FHNO in different veterinary clinics. Clinical and CT scanning evaluations were carried out long time after the procedures had been done. Hip pain, muscle atrophy, decreased range of motion and chronic lameness were observed at clinical examination. Extensive remodelling, unacceptable bone-on-bone contact with bony proliferation involving the femoral neck and acetabulum, but also excessive removal with bone lysis were observed by CT scanning. Revision osteotomy was performed in one dog. Deep gluteal muscle interposition was used, but no improvements were observed postoperatively. This is the first report on the evaluation of three-dimensional CT reconstructions of the late bone remodelling associated with poor clinical outcome in large dogs. The study shows that FHNO could lead to severe functional deficits in large breed dogs. An extensive follow-study is necessary to more accurately determine the frequency of such complications.

An unsatisfactory contract policy

For the last 15 years contract policy has been one of the top priorities of CERN staff, as expressed in successive surveys initiated by the Staff Association. In one’s professional life, having some forward vision of one’s career prospects is the key to loyalty and motivation. On the contrary, instability about the future is always at the root of anxiety, conflicts, or even health problems. A good employer must therefore balance the needs of the Company and those of its employees. CERN’s current contract policy, as described in the Administrative Circular No 2, states that staff members should first obtain a limited duration (LD) contract of up to five years. Then, if they want to stay in the Organization, staff members must apply, usually once a year, and before the end of their LD contract, for an indefinite contract (IC) post. All candidates for an IC post are considered by the Review Board for the award of indefinite contracts (Review Board) which will choose the most suita...

The largest number of patients referred, to age interval from 11 to 30 years (69,6%. More than half of cases were osteochondromas (54%, then solitary bone cyst (14,5% and chondromas (13%. Other nosologic forms were met significantly seldom. Two groups of patients were examined: the main group (with crio-influence - 44 patients and group of comparison (without crio-influence - 87 patients. The plot of operation was in flat, border-line, intrafocusal or segmental resection of damaged section, crio-instillation or contact curio-processing of bone and auto- or allopathic of respected defect. The results of treatment were estimated in a year after operation. After usage of curio-surgical method there were observed positive results in 41 patients, satisfactory - in 2 and unsatisfactory - in 1. The results of treatment with traditional method were positive in 79 cases, satisfactory - in 2, unsatisfactory - in 6. The worked-out method of curio-surgical treatment of foot bone tumours includes resection of pathological focus, itraoperative crio-influence on bone tissue and bone plastic transplantation of resected, defect. The analysis of criosurgical operations of foot gave the foundation to consider such interventions significant and perspective in treatment of patients with tumours and tumour similar damages of foot bone.

The aim is to identify the most frequent problems and to offer alternatives for their solution. From an universal group of 230 patients with aesthetic breast augmentation surgery done from 2004 to 2009, a selective group of 15 patients is presented; out of these, 12 had a surgical procedure done for the first time by another medical team and 3 done by the first author of this paper. After medical evaluation 13 patients had a secondary breast augmentation surgery in order to correct the problems with satisfactory results one year postoperative. Nevertheless, 2 patients had breast stretch marks as first problem in the postoperative period which does not have a definitive solution by now. The possible reasons of the problems are: inadequate or not indicated line of access in 60 %; implant size was excessive in 12 patients (80 %, out of these, 10 patients requested implants with smaller size and 2 did not agree to get new implants; 2 patients (13.3 % suffered implant rupture before the first postoperative year and 1 patient had rupture after 25 years of the surgical procedure; in 12 patients (80 % there was asymptomatic capsular contracture grade I and II and grade III in 3 patients (20 %. There was no information about the manufacturer of the implants in 6 patients (40 % and 10 patients (66 % did not have any information about the importance of having a certificate of guarantee on the implants. We conclude that there is a lack of unified criteria to face the secondary problems after breast augmentation surgery using silicone implants, therefore it is necessary to encourage scientific studies by universities, professional societies and governmental

Full Text Available Background: Valgus foot is a common foot deformity in spina bifida. The most popular operation for the valgus deformity has been the Grice talocalcaneal blocking. It has not been studied primarily in children with spina bifida. We report a prospective series, we present the results of hind foot valgus deformity of children with spina bifida, using Grice talocalcaneal arthrodesis with a tricortical iliac bone graft. Materials and Methods: Between May 2000 and December 2003, 21 patients with bilateral (42 feet valgus deformity of feet underwent surgery. There were 7 males and 14 females. The mean age of patients was 67.7 months (range 50-108 months. Results: The total number of feet that had nonunion was 11, in 7 of them the grafts were completely reabsorbed and the outcome of all these feet was unsatisfactory. Four feet had partial union of which three had unsatisfactory and one had satisfactory outcome. Sixteen feet had residual valgus deformity at the last followup visit, 10 patients had nonunion, and 6 had inadequate correction. Mean preoperative talocalcaneal and calcaneal pitch angles were 48.5΀ and 31.9΀, respectively, which decreased to 38.5΀ and 29.1΀, respectively, postoperatively. The decrease in talocalcaneal angle and calcaneal pitch was significant between preoperative and postoperative measurements (P<0.05. Conclusion: Grice subtalar arthrodesis technique is still a valuable option for valgus foot in patients with spina bifida. In this study, we found more encouraging results in older patients.

CFD optimization of a pellet burner

Full Text Available Increased capacity of computers has made CFD technology attractive for the design of different apparatuses. Optimization of a pellet burner using CFD was investigated in this paper. To make the design tool work fast, an approach with only mixing of gases was simulated. Other important phenomena such as chemical reactions were omitted in order to speed up the design process. The original design of the burner gave unsatisfactory performance. The optimized design achieved from simulation was validated and the results show a significant improvement. The power output increased and the emission of unburned species decreased but could be further reduced. The contact time between combustion gases and secondary air was probably too short. An increased contact time in high temperature conditions would possibly improve the design further.

Effect of external disturbances and data rate on the response of an automatic landing system capable of curved trajectories

Science.gov (United States)

Sherman, W. L.

1975-01-01

The effects of steady wind, turbulence, data sample rate, and control-actuator natural frequency on the response of a possible automatic landing system were investigated in a nonstatistical study. The results indicate that the system, which interfaces with the microwave landing system, functions well in winds and turbulence as long as the guidance law contains proper compensation for wind. The system response was satisfactory down to five data samples per second, which makes the system compatible with the microwave landing system. No adverse effects were observed when actuator natural frequency was lowered. For limiting cases, those cases where the roll angle goes to zero just as the airplane touches down, the basic method for computing the turn-algorithm gains proved unsatisfactory and unacceptable landings resulted. Revised computation methods gave turn-algorithm gains that resulted in acceptable landings. The gains provided by the new method also improved the touchdown conditions for acceptable landings over those obtained when the gains were determined by the old method.

Full Text Available Purpose: Myelomeningocele is one of the most common birth defects. It is associated with severe neurological deficiencies, and ocular changes, such as strabismus, are very common. The purpose of this study was to describe indications for strabismus surgery in patients with myelomeningocele and to evaluate the results achieved with surgical correction. Methods: We retrospectively reviewed records of all patients with myelomeningocele who underwent surgery for strabismus correction in a 5-year period in an institution for disabled children. Results: The main indications for strabismus surgery were esotropia and A-pattern anisotropia. Excellent surgical results were achieved in 60.9% of patients, satisfactory in 12.2%, and unsatisfactory in 26.9%. Conclusion: Patients with myelomeningocele and strabismus had a high incidence of esotropia and A-pattern anisotropia. Strabismus surgery in these patients had an elevated percentage of excellent and satisfactory results, not only for the ocular deviation, but also for improvement of head posture.

Full Text Available Forty cases of Austin Moore Replacement done for transcervical fractures of the femur in patients were reviewed after a period of 12 to 48 months postoperatively (mean 26 mth. 30 cases (75% had mild to severe pain of non-infective origin, starting as early as 6 months postoperatively. This was irrespective of the make, size or position (varus/valgus of the prosthesis. Though the Aufranc and Sweet clinical scoring was satisfactory in 65% cases, radiological evidence of complications like sinking, protrusion, etc. were seen in majority of the cases. Calcar resorption was seen in 34 cases (85% as early as 4 months postoperatively. Results of THR and bipolar replacement done for transcervical fractures in recent literature show 85% pain-free cases at 5 years. We feel that Austin Moore Replacement should be reserved for patients more than 65 years of age and those who are less active or debilitated because of other factors, because of increased acetabular wear with time in the younger individual. This is corroborated by unsatisfactory results in patients less than 65 years of age (p < 0.05.

Full Text Available Numerous procedures have been developed to provide adequate enteral nutrition to patients with gastrointestinal disorders. Previously, operative placement of a feeding gastrostomy or jejunostomy tube was the accepted means of gaining chronic enteral access. However, improved technology and experience with endoscopic techniques have quickly replaced primary operative placement of enteral access. Direct percutaneous endoscopic jejunostomy (D-PEJ is a procedure that was designed to deliver enteral feeding solutions for patients with proximal disease after unsatisfactory results from percutaneous endoscopic gastrostomy tubes with jejunal extensions (PEG-J. As with any procedure, it is associated with complications. We present the first reported case of a colojejunal fistula resulting from a D-PEJ placement. While D-PEJ has been shown to be relatively safe, complications related to the inherent limitations of the procedure need to be considered when the patient experiences unusual post-procedure symptoms and worked up appropriately.

To analyze cases of false diagnoses from a large series to help increase the accuracy of fine needle aspiration of palpable breast lesions. The results of FNA of 835 palpable breast lesions were analyzed to determine the reasons for false positive, false negative and false suspicious diagnoses. Of the 835 aspirates, 174 were reported as positive, 549 as negative and 66 as suspicious or atypical but not diagnostic of malignancy. Forty-six cases were considered unsatisfactory. Tissue was available for comparison in 286 cases. The cytologic diagnoses in these cases were reported as follows: positive, 125 (43.7%); suspicious, 33 (11.5%); atypical, 18 (6.2%); negative, 92 (32%); and unsatisfactory, 18 (6.2%). There was one false positive diagnosis, yielding a false positive rate of 0.8%. This lesion was a case of fibrocystic change with hyperplasia, focal fat necrosis and reparative atypia. There were 14 false negative cases, resulting in a false negative rate of 13.2%. Nearly all these cases were sampling errors and included infiltrating ductal carcinomas (9), ductal carcinomas in situ (2), infiltrating lobular carcinomas (2) and tubular carcinoma (1). Most of the suspicious and atypical lesions proved to be carcinomas (35/50). The remainder were fibroadenomas (6), fibrocystic change (4), gynecomastia (2), adenosis (2) and granulomatous mastitis (1). A positive diagnosis of malignancy by FNA is reliable in establishing the diagnosis and planning the treatment of breast cancer. The false-positive rate is very low, with only a single case reported in 835 aspirates. Most false negatives are due to sampling and not to interpretive difficulties. The category "suspicious but not diagnostic of malignancy" serves a useful purpose in management of patients with breast lumps.

The objective of this study was to evaluate the patterns of use of complementary alternative medicine (CAM) in a representative adult population in Germany. A population-based telephone survey was conducted in Lübeck, Germany. We performed computer-assisted telephone interviews (CATI) in order to obtain information on demographics, health status, prevalence of CAM usage, motivation for using CAM, type of CAM and health problems for which CAM were used. 1,001 adults (median age 48 years) participated in the study (response 46.8%). 79.6% of the interviewed subjects reported health problems. The most frequently named problems were chronic pain (45.3%), circulation problems (32.9%) and colds with fever (27.8%). Non-users of CAM had a lower incidence (76.6%) of overall illness than users (83.5%) (OR 0.65, 0.47-0.89). 42.3% of the participants had used CAM. The CAM user group consisted of significantly more females (72.8 vs. 55.5%) (OR 2.32, 1.74-3.08) and involved better educated subjects (school education >12 years, 36.6 vs. 27.9%, OR 3.25, 1.35-7.81) than the non-user group. The main health problems for which CAM was used were chronic pain (36.3%), some cases of uncomplicated colds (16.9%) and for improving general health (14.7%). Three procedures accounted for the majority of usage: Acupuncture (34.5%), homeopathy (27.3%) and herbal medicine (9.7%). A large number of participants reported as the main reason for using CAM the wish to avoid drugs as much as possible (31.7%). 26.7% reported opting for CAM due to the recommendation of their physician. 23.9% gave unsatisfactory results of conventional medicine as reason for CAM usage. CAM is used widely for different complaints by the general population. This frequent use of CAM has implications for the health-care system and health policy.

Full Text Available Purpose. To summarize the experience in treating patients with genitoplasty due to disorders of sex development in China. Methods. The operative procedures, gender of rearing, surgical outcome, and psychosocial and family adjustments of 262 patients were reviewed retrospectively. Results. At initial diagnosis, the mean age was years (range: 2–38 years. There were 96 children, 133 adolescents, and 33 adults. Follow-up was done every 6 months. Patients with female sex assignment had no urinary incontinence or voiding difficulty. Five patients underwent the second surgery (3%; vaginal dilation was performed in 35 patients with postoperative vaginal stenosis; 12 patients (7.4% were unsatisfactory with the outcome. For patients with male sex assignment, the median length of penis was 2.2 cm in prepubertal patients, 4.2 cm in pubertal patients, and 5.0 cm in adults; 39 patients developed postvoid dribbling (39%; 21 patients underwent a second surgery (21%; urethral dilation was done in 28 patients (28% due to urethral stricture; 38 patients were unsatisfactory with the outcome (38%. In addition, 136 patients (83% with female sex assignment and 54 (54% with male sex assignment had favorable psychosocial adjustment. Conclusions. Patients with male sex assignment have more surgical complications and difficulties in psychosocial adjustment as compared to those with female sex assignment.

Quality of life is a subjectively interpreted phenomenon that can be profoundly altered by the presence of a wound. Particularly when complete and expedient healing seems unrealistic, quality of life becomes the focus of care. To assess the influence of a variety of chronic wounds on patient quality of life, a 1-day, descriptive study was conducted among 50 consecutive outpatients (64% men, 36% women; age range 14 to 78 years) with chronic wounds who attended the Wound Clinic of the University Hospital, Varanasi, India. A quality-of-life questionnaire containing six parameters (physical activities, feelings, household duties, leisure time activities, social relations, and general activities) was developed and administered. Demographic information was available as a result of a previous study at this institution. Quality-of-life scores were grouped as satisfactory and unsatisfactory and participants were grouped by age (60 years old). Wounds were classified by cause (diabetes, venous disease, pressure ulcer, and tuberculosis) and size (50 cm2). The most common site was the lower limb or foot (39, 78%), followed by upper limb (six, 12%) and head, neck, and trunk (five, 10%). More than half (28, 56%) of all patients had an unsatisfactory overall quality-of-life score. The percentage of patients with satisfactory scores was higher in patients with smaller versus larger wounds and wounds located on upper rather than lower limbs, as well as in middle-aged versus younger or older patients. This patient-centered instrument helped document important quality-of-life concerns among chronic wound patients.

Differences of crystallographic texture of zircaloy-4 plate depends on cold working and heat treatment.To determine the change of zircaloy-4 textures, the solid solution treatment process at beta phase which was followed by quenching on water was employed for this sample. The next step was cold rolling until deformation epsilon = 1.62. The specimens were recrystallized at 750 o C, for 2 hours. The result of beta-quench gave a spread and different orientations and the main orientation occurred at (0001)[1010] and (0001)[1120]. Result of cold rolling with epsilon = 1.39 and epsilon 1.62 is the deformation texture at the main orientation of (0001)[1010] with the angle of inclination was around 38 o. However, the result of Recrystallization process on 750 o C for 2 hours gave annealing textures with orientations of (0001)[1120]. It means that the recrystallization process of zircaloy-4 plate can not remove the deformation textures, but can change the crystallographic orientation

The Use of Data Mining Methods to Predict the Result of Infertility Treatment Using the IVF ET Method

Directory of Open Access Journals (Sweden)

Malinowski Paweł

2014-12-01

Full Text Available The IVF ET method is a scientifically recognized infertility treat- ment method. The problem, however, is this method’s unsatisfactory efficiency. This calls for a more thorough analysis of the information available in the treat- ment process, in order to detect the factors that have an effect on the results, as well as to effectively predict result of treatment. Classical statistical methods have proven to be inadequate in this issue. Only the use of modern methods of data mining gives hope for a more effective analysis of the collected data. This work provides an overview of the new methods used for the analysis of data on infertility treatment, and formulates a proposal for further directions for research into increasing the efficiency of the predicted result of the treatment process.

Results of radioiodine therapy using different radiation doses in patients suffering from immunogenic and non-immunogenic hyperthyroidism

International Nuclear Information System (INIS)

Moser, E.

1992-01-01

During the past few years high rates of recidivation have increasingly been reported following drug treatment for hyperthyroidism. In view of these unsatisfactory results it is only natural that the use of surgery and ratioiodine treatment is now more often considered in order to achieve complete elimination of the metabolic disorders caused by hyperactivity of the thyroid gland. The aim of this study was to investigate into the effectiveness of radioiodine therapy in a large cohort of patients (n = 925). Particular attention was given to the influence of the dose applied to the thyroid tissue on the rates of success achieved in immunogenic hyperthyroidism (IH) and autonomous disorders (non-immunogenic hyperthyroidism = NIH).

Full Text Available Trapping by specific sex pheromones initiated in 2009 to monitor three pests, peach twig borer (Anarsia lineatella, oriental fruit moth (Cydia molesta and plum fruit moth (Grapholita funebrana revealed the greater importance of peach twig borer in comparison to the others. The results of monitoring the development of larval stages over time and the accumulated degree-days from biofix show that the pest develops five generations per year, one of which undergoes a diapause. In 2009 and 2010 chemical control based on tolerance threshold of 10 males/trap/2 weeks showed unsatisfactory results. With this method, the percentage of affected fruits increased from 6.8% in 2009 to 18.6% in 2010 despite the application of four treatments of organophosphate-based insecticides in 2009 and the application of four treatments in 2010 using active ingredients from different chemical families (pyrethroid, organophosphate and chlorinicotinyl. On the other hand, management of the peach twig borer by the degree-days method tested and planned on the basis of a bifenthrin treatment between 150 to 204 degree-days accumulated from biofix, gave interesting results where the percentage of affected fruits hardly exceeded 0.5% over the four years of study

G. Kunkel

1983-11-01

Full Text Available Although the flora of Africa is rather poor in plant species when compared to the floras of Tropical America or South-east Asia, this vast continent is the home of a wide range of plants useful to Man. Many of these have become famous in cultivation around the world. Coffee now provides an important source of income for certain countries, and the Yams yield one of the world’s staple foods. The Oil Palm and Cola trees are widely cultivated in Africa itself and elsewhere. African Mahoganies and Ironwoods are much sought after timber trees of excellent quality. Numerous grasses and pulses are well-known for their food value, and some of the native Cucurbitaceae are appreciated additions to our vegetable diet. African plants have also made their contribution to horticulture, ranging from world-famous trees such as the African or Gabon Tulip tree and many of the South African species of Proteaceae to the multitude of East and South African succulents. The present paper provides a survey of the most important of these useful plants and will emphasize the need of further research for forestry and agricultural as well as horticultural purposes, especially as far as some still little-known but potentially important plants species are concerned.

Ducassou, D.; Brendel, A.; Nouel, J.P.

1978-01-01

A modification of the method of Thakur et al. for labelling polynuclear cells with 8-hydroxyquinolein-indium-complexe utilising the water soluble sulfate of the substance was applied. The labelling procedure gave a yield over 98% with erthrocytes and over 80% with platelets and polynuclear cells using at least 1 x 10 8 plasma free cells. Functional capacity of the labelled cells remained unaltered. Injection double labelled ( 111 In, 51 Cr) red cells correlation of values for the red cell volume amounted to r = 0,98 (n=20); red cell life-spane measurements gave comparable results in 5 patients. After injecting labelled platelets a life-spane between 6,5 and 11 days was measured. Scintigraphic visualisation of pulmonary embolism was obtained 30 minutes after injecting labelled platelets. Injection of labelled polynuclear cells allows life-spane measurements as well as detection of abscesses. (author)

In this paper selected results obtained by the ALICE experiment at the LHC will be presented. Data collected during the pp runs taken at sqrt(s)=0.9, 2.76 and 7 TeV and Pb-Pb runs at sqrt(s_NN)=2.76 TeV allowed interesting studies on the properties of the hadronic and nuclear matter: proton runs gave us the possibility to explore the ordinary matter at very high energy and up to very low pt, while Pb-Pb runs provided spectacular events where several thousands of particles produced in the interaction revealed how a very dense medium behaves, providing a deeper picture on the quark gluon plasma(QGP) chemical composition and dynamics.

To evaluate the clinical effectiveness of fluoroscopically guided balloon dilation in the treatment of esophageal achalasia. Under fluoroscopic guidance, 21 balloon dilation procedures were performed in 14 patients with achalasia. A balloon with a diameter of 20 mm was used for the initial attempt.If the patient tolerated this well, the procedure was repeated with a 10-20 mm balloon, placed alongside at the same session. If, however the patient complained of severe chest pain and/or a postprocedural esophagogram showed an improvement,the additional balloon was not used. For patients whose results were unsatisfactory, the dilation procedure was repeated at sessions three to seven days apart. Succesful dilation was achieved in 13 of 14 patients(92.9%), who needed a total of 20 sessions of balloon dilation, ranging from one to three sessions per patient(mean, 1.54 sessions). Esophageal rupture occured in one of 14 patients(7.1%) ; of the 13 patients who underwent a successful dilation procedure, 12(92.3%) were free of recurrent symptoms during the follow-up period of 1-56(mean, 18.5) months. The remaning patient(7.7%) had a recurrence seven months after dilation. Fluoroscopically guided balloon dilation seems to be safe and effective in the treatment of esophageal achalasia.

Fine-needle aspiration biopsy (FNAB) may yield different results depending on its operator. We compared the proportions of unsatisfactory aspirates obtained by pathologists vs. surgeons. In a retrospective review, all FNAB reports and slides performed between March 2002 and February 2003 were grouped by organ/site and according to whether they were done by pathologist or a surgeon. The proportions of unsatisfactory aspirates for pathologists and surgeons were compared. Of 692 FNAB's, 390 were performed by pathologists at the FNAC clinic and the remainder by surgeons. Overall, 15.5% of aspirates obtained were unsatisfactory (n=107). Of aspirates obtained by surgeons, 29.5% were unsatisfactory, compared to 4.6% of those obtained by pathologists (P<0.001). Pathologists had significantly lower proportions of unsatisfactory aspirates in all sites. A 33% reduction in the number of lymph node excisional biopsies has been reported subsequent to establishment of the FNAC clinic. The advantages of a pathologist performing FNAB are that a rapid evaluation can be rendered regarding specimen adequacy and the need for repeating the procedure. In addition, pathologists can direct the distribution of aspirated material for other tests such as culture study, flow cytometry and electron microscopy, as indicated by preliminary evaluation of the smears. These factors significantly lower the proportions of unsatisfactory specimens and improve the diagnstic accuracy of FNAB technique. (author)

Sarcia, J.A.; Bonnet, J.; Combe, R.

1960-01-01

The authors discuss the difficulties encountered in the exploration of a typical deposit in the Nord-Limousin, using the resistivity measurement method. In the zone in question the over-thrust was very variable and difficult to predict. The uraniferous deposits had two types of aspect, the passage from one to the other being often very sudden: long thin veins without gangue; short and thick lens-shape deposits which were strongly contaminated by clay towards their edges. After several unsatisfactory attempts, the device known as the 'rectangular map' was adopted and gave an acceptable structural representation rapidly and cheaply. For the placing of the probes however, methods are required which are more refined and sensitive. It is in any case useless to expect to obtain a satisfactory representation and a sufficient accuracy using a single technique; especially in the region under consideration. (author) [fr

Time-averaged paleomagnetic field at the equator: Complete data and results from the Galapagos Islands, Ecuador

Gromme, Sherman; Mankinen, Edward A.; Prévot, Michel

2010-01-01

We present here the complete paleomagnetic laboratory results from a collection of approximately 1500 oriented cores from all 16 of the Galapagos Islands, Ecuador, collected by Allan Cox in 1964–1965 but nearly all previously unpublished. The islands are located in the eastern Pacific Ocean within 1.4° of latitude from the equator and range in age from historically erupted to 3 Ma, mostly determined by published K-Ar and 3He isotopic dating. The number of sites collected on each island ranges from 1 to 28, for a total of 186. After combining duplicate site mean directions, 149 are used for an overall mean direction and 8 represent excursions and one reversal path. Divided by geomagnetic polarity chron, 110 site means are Brunhes or Jaramillo (normal polarity), 27 are Matuyama (reversed polarity), and 12 are Gauss (both polarities). We have completed the magnetic cleaning that was commenced in the late 1960s. Secondary (mostly viscous) magnetizations were nearly all removed by alternating field demagnetization at 10 mT. We have used the so-called blanket cleaning method, generally at 10 mT. All sites were in basalt flows and gave good paleomagnetic results; none was rejected in toto, and only a few core specimens were magnetically unsatisfactory. Nearly all sites had eight independently oriented cores, and within-site angular standard deviations of directions range from 1° to 8°. We used both Fisher and Bingham statistics to analyze the data and found that many of the direction populations are strongly elongate along the paleomagnetic meridian, while the corresponding virtual pole (VGP) populations are essentially circularly distributed. The paleomagnetic poles, calculated as the means of VGPs, are as follows: Brunhes and Jaramillo, north latitude = 86.9°, east longitude = 245.1°, and 95% confidence radius A95 = 1.9°; Matuyama, latitude = 87.2°, longitude = 158.2°, and A95 = 3.8°; Gauss, latitude = 83.0°, longitude = 204.7°, and A95 = 7.0°.

An emitter made of a directionally solidified Mo-Al 2 O 3 , Cr 2 O 3 eutectic was provided by Eindhoven University of Technology in Eindhoven, The Netherlands. Although the high temperature braze cycle used in bonding this electrode to the emitter substrate destroyed its characteristic needle microstructure, the converter gave good performance. Apparently, chemical species evaporated from the emitter onto the collector provided a low collector work function. The resulting low barrier indices suggest that this surface is a promising emitter

Has the ThinPrep method of cervical screening maintained its improvement over conventional smears in terms of specimen adequacy?

LENUS (Irish Health Repository)

Treacy, A

2009-04-01

Liquid-based cytology (LBC) has replaced conventional smear assessment in many centers over recent years. In our laboratory this transfer took place in 1999. At that time we performed a split sample study comparing the conventional method of cervical smear evaluation with the ThinPrep system. This split sample study identified a dramatic improvement in specimen adequacy with LBC. While 11% of conventional preparations were reported as unsatisfactory and almost 9% were reported as suboptimal, evaluation of the same cases using LBC saw this combined figure reduced to 2.3%. AIM: To evaluate whether this dramatic fall in unsatisfactory smears has been maintained with the use of LBC. The database for all smears reported for 2005 (100% LBC) was interrogated. The number of unsatisfactory reports was calculated. The reason for an unsatisfactory report was recorded for each case. The overall unsatisfactory rate was compared with that reported in the 1999 split sample study. A total of 41,312 smear tests were reported in 2005. 1,342 (3.25%) were reported as unsatisfactory. Our findings support the ongoing value of LBC in a routine cervical screening laboratory in terms of continuing to maintain a low rate of unsatisfactory smears.

An improved bioassay for fluconazole was developed. This assay is sensitive in the clinically relevant range (2 to 40 micrograms/ml) and analyzes plasma, serum, and cerebrospinal fluid specimens; bioassay results correlate with results obtained by high-pressure liquid chromatography (HPLC). Bioassay and HPLC analyses of spiked plasma, serum, and cerebrospinal fluid samples (run as unknowns) gave good agreement with expected values. Analysis of specimens from patients gave equivalent results by both HPLC and bioassay. HPLC had a lower within-run coefficient of variation (less than 2.5% for HPLC versus less than 11% for bioassay) and a lower between-run coefficient of variation (less than 5% versus less than 12% for bioassay) and was more sensitive (lower limit of detection, 0.1 micrograms/ml [versus 2 micrograms/ml for bioassay]). The bioassay is, however, sufficiently accurate and sensitive for clinical specimens, and its relative simplicity, low sample volume requirement, and low equipment cost should make it the technique of choice for analysis of routine clinical specimens.

In order to develop suitable storage conditions in potatoes for processing use, non-irradiated and irradiated potatoes var. Norin No. 1 were stored in containers and in bulk. The contents of reducing sugars were determined and the properties of potato chips were analysed. Reconditioning at 10 deg C and RH 90 % for 4 weeks during an early period of dormancy lowered the content of reducing sugars remarkably in both the non-irradiated and irradiated potatoes which were either stored in containers or in bulk. The optimum conditions for the storage of potatoes were 8 deg C and RH 90 %, which enabled the potatoes to retain their hardness while the content reducing sugars decreased. The potatoes stored under the above conditions gave chips with a fairly good color. In contrast, the non-irradiated potatoes stored for a period of 6 months or longer sprouted and aged, resulting in chips with unsatisfactory color. It was found necessary to use potatoes with low contents of both amino acids and reducing sugars to avoid the browning of chips. Bulk storage which was found to be effective for air circulation through potatoes caused creeping phenomenon. (author)

Full Text Available Background: the occurrence of psychogenic non-epileptic seizures (PNES is estimated to be between 2 to 33 cases in every 100,000 inhabitants. The number of patients with PNES reaches 19% of those treated as epileptics. Patients with PNES are treated as if they had intractable epilepsy, with unsatisfactory results even after medication treatment is used to its maximum. The aim of this study is to present the effects of individual psychoanalytical treatment in patients with PNES, assessing its impact in the evolution of the clinical picture and its association with sex, time of disease, social, psychological and professional harm, as well as going through with treatment. Methods: The case base was composed of 37 patients with PNES. The diagnosis was reached with video-EEG monitoring. Psychoanalytical treatment was carried out through 12 months of weekly sessions timed for around 50-minutes each, in a total of 48 individual sessions. Results: This study found a high rate of success in the treatment of PNES patients. 29.7% (n=11 of patients had cessation or cure of symptoms and 51.4% (n=19 had a decrease in the number of episodes. There is an association between cessation or decrease in the number of episodes and sex (p<0.01, religion (p<0.01 and concluding treatment (p<0.01. Conclusion: Individual psychoanalytical treatment applied to patients with PNES is considered effective and can be an essential form of assistance for the reduction or cessation of episodes.

1983-01-01

Between May, 1973 and December, 1980, 78 Stage I and II breast carcinomas in 76 patients were treated by biopsy and radiotherapy with curative intent. With a maximum follow-up of 10 years, a minimum of 2 1/2 years and a median follow-up of 3 1/2 years, a loco-regional control rate of 97% was obtained. Cosmetic results and treatment complications were studied. Patient characteristics, tumor size, excisional biopsy technique, axillary staging procedure and radiotherapy techniques were analyzed and all found to be important factors affecting cosmesis and complications. The most common complications included transient breast edema observed in 51% of patients, breast fibrosis (usually mild) seen in 23% of the population, axillary hematoma or seroma formation in 15%, mild arm edema in 14% and basilic vein thrombosis in 10% of patients. The causes of these and other less frequent complications are discussed. The overall cosmetic result was excellent in 78%, satisfactory in 18% and unsatisfactory in 4% of patients. Recommendations for improving cosmetic results and minimizing complications are made

Relating Fresh Concrete Viscosity Measurements from Different Rheometers.

Ferraris, Chiara F; Martys, Nicos S

2003-01-01

Concrete rheological properties need to be properly measured and predicted in order to characterize the workability of fresh concrete, including special concretes such as self-consolidating concrete (SCC). It was shown by a round-robin test held in 2000 [1,2] that different rheometer designs gave different values of viscosity for the same concrete. While empirical correlation between different rheometers was possible, for a procedure that is supposed to "scientifically" improve on the empirical slump tests, this situation is unsatisfactory. To remedy this situation, a new interpretation of the data was developed. In this paper, it is shown that all instruments tested could be directly and quantitatively compared in terms of relative plastic viscosity instead of the plastic viscosity alone. This should eventually allow the measurements from various rheometer designs to be directly calibrated against known standards of plastic viscosity, putting concrete rheometry and concrete workability on a sounder materials science basis.

In the synthesis of dipeptides (Boc-AA(1)-AA(2)-OPac: AA(1) and AA(2) represent amino acids) protected by phenacyl (Pac) ester, amines and solid bases as the base for the conversion of the trifluoroacetic acid (TFA) salt of the amino component (TFA·H-AA(2)-OPac) into the corresponding free amino component (H-AA(2)-OPac) were examined. The synthesis of a dipeptide (Boc-Ala-Gly-OPac) using amines for the conversion afforded an unsatisfactory yield with by-products. On the other hand, the use of neutral alumina-supported Na(2) CO(3) (Na(2)CO(3) /n-Al(2)O(3)) as a solid base for the conversion provided the dipeptide in a quantitative yield without by-products. The application of Na(2)CO(3) /n-Al2 O3 to the synthesis of some dipeptides protected by Pac ester gave the desired peptides in excellent yields.

Because the use of magnetic resonance imaging is still not universal for the patients with developmental dysplasia of the hip patients, orthopaedists do not generally distinguish widened joint spaces which are "empty" after primary treatment (and therefore still reducible), from those which are filled and much more difficult to treat. To date no studies have focused on the latter hips. We treated and observed the outcomes for 19 hips which showed filled joint spaces after primary treatment. We retrospectively reviewed 19 cases of developmental dysplasia of the hip: (1) who showed a widened joint space on radiographs after primary treatment; and (2) whose magnetic resonance imaging showed that the widened joint space was accompanied by acetabular cartilage hypertrophy and/or was filled with fibrous tissues. All patients were over 1 year old at the time of primary reduction (reduction was closed in 4 patients, open in 6, and open with pelvic osteotomy in 9). Thirteen patients received at least 1 secondary treatment. Final results were classified using a modified Severin classification. Final outcomes were satisfactory in 10 (52.6%) and unsatisfactory in 9 (47.4%). The widened joint spaces gradually filled with bone, resulting in a shallow acetabulum in the patients with unsatisfactory results. Of 9 patients who underwent combined pelvic osteotomy at the time of primary reduction, results were satisfactory in 6 (66.7%), whereas all patients who had only closed or open primary reduction had unsatisfactory results. Combined pelvic osteotomy at the time of primary reduction is advisable in hips with widened joint spaces. However, hips with filled joint spaces after primary treatment often have unsatisfactory results even after additional pelvic and/or femoral osteotomy. Level IV-prognostic study.

Investigation of the results of therapy of anaplastic thyroid gland carcinomas

1979-01-01

The results of the treatment of 28 patients with an anaplastic thyroid gland carcinoma are investigated, to see whether an optimal therapy is indicated. The execution of an operation before radiotherapy does not appear to improve the prognosis (statistically this conclusion is not wholly justified). The presence of metastases at the beginning of the therapy gave rise to a worse prognosis than the absence of metastases. The combination treatment of chemotherapy and either surgery or radiotherapy was only applied to two patients so no conclusions can be made about its benefit. (C.F.)

Two studies of retail fresh, ripened and semi-hard cheeses made from raw, thermized or pasteurized milk were undertaken in the UK during 2004 and 2005 to determine the microbiological quality of these products. Using microbiological criteria in European Commission Recommendations 2004/24/EC and 2005/175/EC, 2% of both raw, thermized (37/1819 samples) and pasteurized (51/2618 samples) milk cheeses were of unsatisfactory quality. Raw or thermized milk cheeses were of unsatisfactory quality due to levels of Staphylococcus aureus at 10(4)cfu g(-1), Escherichia coli at 10(5)cfu g(-1), and/or Listeria monocytogenes at 10(2)cfu g(-1), whereas pasteurized milk cheeses were of unsatisfactory quality due to S. aureus at 10(3)cfu g(-1) and/or E. coli at 10(3)cfu g(-1). Salmonella was not detected in any samples. Cheeses were of unsatisfactory quality more frequently when sampled from premises rated as having little or no confidence in management and control systems, and stored/displayed at above 8 degrees C. Raw or thermized milk cheeses were also more likely to be of unsatisfactory quality when they were unripened types, and pasteurized milk cheeses when they were: semi-hard types; from specialist cheese shops or delicatessens; cut to order. These results emphasize the need for applying and maintaining good hygiene practices throughout the food chain to prevent contamination and/or bacterial growth. Labelling of cheeses with clear information on whether the cheese was prepared from raw milk also requires improvement.

Radiographs of the middle ear were made in five dogs 60 to 78 months after ventral bulla osteotomy was performed to treat otitis media. The clinical results of surgery were considered satisfactory in four dogs and unsatisfactory in one. In 4 dogs with satisfactory results, radiographs demonstrated complete reformation of the bulla in 3 operated middle ears (3 dogs), with partial bulla reformation in the three middle ears (3 dogs). Radiographs in one dog with unsatisfactory results showed complete bulla reformation with no increase in lumen opacity. The proliferative bony response obliterating the middle ear previously reported in normal dogs after ventral bulla osteotomy was not seen in any of these patients

Cretaceous choristoderan reptiles gave birth to live young

Viviparity (giving birth to live young) in fossil reptiles has been known only in a few marine groups: ichthyosaurs, pachypleurosaurs, and mosasaurs. Here, we report a pregnant specimen of the Early Cretaceous Hyphalosaurus baitaigouensis, a species of Choristodera, a diapsid group known from unequivocal fossil remains from the Middle Jurassic to the early Miocene (about 165 to 20 million years ago). This specimen provides the first evidence of viviparity in choristoderan reptiles and is also the sole record of viviparity in fossil reptiles which lived in freshwater ecosystems. This exquisitely preserved specimen contains up to 18 embryos arranged in pairs. Size comparison with small free-living individuals and the straight posture of the posterior-most pair suggest that those embryos were at term and had probably reached parturition. The posterior-most embryo on the left side has the head positioned toward the rear, contrary to normal position, suggesting a complication that may have contributed to the mother’s death. Viviparity would certainly have freed species of Hyphalosaurus from the need to return to land to deposit eggs; taking this advantage, they would have avoided intense competition with contemporaneous terrestrial carnivores such as dinosaurs.

Full Text Available Abstract Background Early diagnosis and referral to treatment prior to age 3–5 years improves the prognosis of children with Autism Spectrum Disorder (ASD. However, ASD is often not diagnosed until age 3–4 years, and medical providers may lack training to offer caregivers evidence-based treatment recommendations. This study tested hypotheses that 1 children with ASD would be diagnosed between ages 3–4 years (replicating prior work, 2 caregivers would receive little information beyond the diagnosis from their medical providers, and 3 caregivers would turn to other sources, outside of their local health care professionals, to learn more about ASD. Methods 146 ASD caregivers responded to an online survey that consisted of questions about demographics, the diagnostic process, sources of information/support, and the need and availability of local services for ASDs. Hypotheses were tested using descriptives, regression analyses, analyses of variance, and chi-squared. Results The average age of diagnosis was 4 years, 10 months and the mode was 3 years. While approximately 40% of professionals gave additional information about ASD after diagnosis and 15–34% gave advice on medical/educational programs, only 6% referred to an autism specialist and 18% gave no further information. The diagnosis of Autism was made at earlier ages than Asperger's Disorder or PDD-NOS. Developmental pediatricians (relative to psychiatrists/primary care physicians, neurologists, and psychologists were associated with the lowest age of diagnosis and were most likely to distribute additional information. Caregivers most often reported turning to the media (i.e., internet, books, videos, conferences, and other parents to learn more about ASD. Conclusion The average age of ASD diagnosis (4 years, 10 months was later than optimal if children are to receive the most benefit from early intervention. Most professionals gave caregivers further information about ASDs, especially

Based on the results of 19 food microbiology proficiency testing (PT) schemes, this study aimed to assess the laboratory performances, to highlight the main sources of unsatisfactory analytical results and to suggest areas of improvement. The 2009-2015 results of REQUASUD and IPH PT, involving a total of 48 laboratories, were analysed. On average, the laboratories failed to detect or enumerate foodborne pathogens in 3·0% of the tests. Thanks to a close collaboration with the PT participants, the causes of outliers could be identified in 74% of the cases. The main causes of erroneous PT results were either pre-analytical (handling of the samples, timing of analysis), analytical (unsuitable methods, confusion of samples, errors in colony counting or confirmation) or postanalytical mistakes (calculation and encoding of results). PT schemes are a privileged observation post to highlight analytical problems, which would otherwise remain unnoticed. In this perspective, this comprehensive study of PT results provides insight into the sources of systematic errors encountered during the analyses. This study draws the attention of the laboratories to the main causes of analytical errors and suggests practical solutions to avoid them, in an educational purpose. The observations support the hypothesis that regular participation to PT, when followed by feed-back and appropriate corrective actions, can play a key role in quality improvement and provide more confidence in the laboratory testing results. © 2015 The Society for Applied Microbiology.

Regular service audits since 2008 gave a stoma care department confidence in the service it provides. In 2016 the department undertook a new audit to benchmark its services, using the Association of Stoma Care Nurses (ASCN) UK Revised Stoma Care Nursing Standards and Audit Tool (2015) . Of the 60 questionnaires given out, 43 were returned (71%). The results highlighted areas of good practice with positive patient feedback. However, it also identified that the team needed to improve documentation when offering patients the opportunity to meet a former patient with a stoma preoperatively and when discussing lifestyle issues. The results demonstrated poor preoperative compliance; this was lower than expected and did not concur with department statistics. The audit highlights the importance of clarity when developing a questionnaire to ensure all respondents not only interpret its meaning in the same way, but also only answer the questions specific to them.

Objective: To study the use and effects of Karapandzic technique of lip reconstruction by long-term assessment. Results: A total of 37 patients were included in the study. Thirteen (35%) patients were outdoor cases while 24 (65%) were in-patients. Average time of reconstruction was 40 minutes, which was done under general anesthesia in 21(57%) patients and under local anesthesia in 16 (43%) cases. Mean hospital stay of the indoor cases was 26 hours. There was no flap loss except for marginal necrosis in 04 (11%) patients. Wound infection and wound dehiscence was observed in 03 (08%) patients. Sensations were completely intact in 29 (78%) patients and aesthetically 28 (76%) patients gave normal look at the end of two years (2Y). Twenty-seven (74%) patients had no change in speech and only one (3%) patient had unsatisfactory speech after 2 years. Varying degree of microstomia was observed in all the cases at immediate postoperative stage of one month but 35 (95%) patients showed gradual improvement with active mouth opening and stretching by prosthetic splints over 2 years. Conclusion: The Karapandzic technique of lip reconstruction is strongly recommended over the other techniques as it is a single stage, quick and safe procedure which gives cosmetically and functionally excellent results. Microstomia, occurring in early postoperative stage, shows gradual improvement on long-term follow-up. (author)

A microbiological study of cold, ready-to-eat sliced meats from 2579 catering establishments (public houses, hotels, cafés, restaurants, residential homes and other catering premises) found that 2587 of 3494 samples (74%) were of acceptable quality, 892 (26%) were of unsatisfactory quality and 15 (quality. Unacceptable results were due to high levels of Escherichia coli, Staphylococcus aureus, Listeria species and/or Clostridium perfringens. Unsatisfactory results were mostly due to high Aerobic Plate Counts. The microbiological quality of cold, ready-to-eat meats was associated with meat type, premises type, management training, hygienic practices, meat supplier and length of storage. The relationship between food hygiene training and microbiological quality is discussed.

Objective: To determine the thyroid status of mother's of newborns with primary congenital hypothyroidism. Methodology: Thyroid function tests were carried out on 80 mothers of hypothyroid newborns and 80 mothers of non-hypothyroid newborns as control. Results: The mean difference of the tests revealed that mothers of congenitally hypothyroid infants had a lower triiodothyronine resin uptake (T3RU) concentrations compared with the control population. The higher value of free thyroxin index (FTI) in case group showed a tendency to significance. The proportional frequency distribution showed; T3RU and triiodothyronine (T3) had a significant difference, and FTI showed a tendency to significance. There were no significant differences between; thyroid-stimulating hormone (TSH), thyroxine (T4) and anti-thyroid peroxidase antibodies (anti-TPO) in two groups. Conclusions: These results indicated that at least some cases of primary congenital hypothyroidism were attributable to the maternal thyroid disease. Therefore, we recommend that each pregnant woman should be assessed for thyroid function in region with a high prevalence of thyroid disease. (author)

Survey of the results of oil prospecting in Northern Bosnia

Energy Technology Data Exchange (ETDEWEB)

Soklic, I

1972-06-01

Oil prospecting in N. Bosnia was undertaken from 1898 till 1899, 1929 till 1941 and 1948 till 1963. Besides geological and geophysical prospecting, prospecting drillings have also been performed. Basic data of the results, especially of those in the post-war period, are given. Crude oil in the Tuzla Basin has been found in the Eocene and the middle Miocene-strata of the marine origin, as well as in freshwater Oligomiocene. The accumulation of oil in Pozarnica near Tuzla has the character of unsufficiently drained fissure bed. Test production gave 800 tons of oil before the last war. In Bosanska, Posavina and Semberija, the prospecting wells are located on the highest parts of pre-Neogene relief. (18 refs.)

Blast tests of expedient shelters in the DICE THROW event

International Nuclear Information System (INIS)

Kearny, C.H.; Chester, C.V.

1978-03-01

To determine the worst blast environments that eight types of expedient shelters can withstand, we subjected a total of 18 shelters to the 1-kiloton blast effects of Defense Nuclear Agency's DICE THROW main event. These expedient shelters included two Russian and two Chinese types. The best shelter tested was a Small-Pole Shelter that had a box-like room of Russian design with ORNL-designed expedient blast entries and blast doors added. It was undamaged at the 53-psi peak overpressure range; the pressure rise inside was only 1.5 psi. An unmodified Russian Pole-Covered Trench Shelter was badly damaged at 6.8 psi. A Chinese ''Man'' Shelter, which skillfully uses very small poles to attain protective earth arching, survived 20 psi, undamaged. Two types of expedient shelters built of materials found in and around most American homes gave good protection at overpressures up to about 6 psi. Rug-Covered Trench Shelters were proved unsatisfactory. Water storage pits lined with ordinary plastic trash bags were proven practical at up to 53 psi, as were triangular expedient blast doors made of poles

Lectures on probability and statistics

International Nuclear Information System (INIS)

Yost, G.P.

1984-09-01

These notes are based on a set of statistics lectures delivered at Imperial College to the first-year postgraduate students in High Energy Physics. They are designed for the professional experimental scientist. We begin with the fundamentals of probability theory, in which one makes statements about the set of possible outcomes of an experiment, based upon a complete a priori understanding of the experiment. For example, in a roll of a set of (fair) dice, one understands a priori that any given side of each die is equally likely to turn up. From that, we can calculate the probability of any specified outcome. We finish with the inverse problem, statistics. Here, one begins with a set of actual data (e.g., the outcomes of a number of rolls of the dice), and attempts to make inferences about the state of nature which gave those data (e.g., the likelihood of seeing any given side of any given die turn up). This is a much more difficult problem, of course, and one's solutions often turn out to be unsatisfactory in one respect or another

Modification of the code BEAMCORR, and some simulation results of the magnet and achromat misalignments for the SLC South Arc

International Nuclear Information System (INIS)

Shoaee, H.; Kheifets, S.

1984-01-01

An important decision has been made regarding the correction scheme for the arcs leading to the adoption of the so called scheme I. In this scheme the beam position data are collected from single-plane x and y Beam Position Monitors (BPMs), which are placed in the drift spaces adjacent to the downstream D- and F-magnets correspondingly. Similarly, single-plane x and y correctors are used for moving the upstream end of the corresponding magnets. In the present simulation this scheme is used exclusively. The first order calculations performed by means of TRANSPORT appear to be unsatisfactory from the point of view of the beam spotsize at the interaction point (IP). In this note we describe the modification to our program BEAMCORR which employs second order calculations by means of the program TURTLE. We also present the results of the following simulations: (a) study of the effects of two different levels of magnet misalignment on the beam spotsize at IP, and comparison of the results with those obtained by means of the program DINGBAT; (b) study of disjoints between achromats (both the displacement of the adjacent ends and angular discontinuity between achromats)

To examine whether chewing ability affects healthcare use and expenditure and whether improving dietary quality alleviates any such effects. Prospective cohort. The Elderly Nutrition and Health Survey in Taiwan (1999-2000), a nationwide community-based survey of people aged 65 and older. Individuals aged 65 and older (N = 1,793; 903 men, 890 women). Chewing ability (satisfactory or unsatisfactory) was assessed using a questionnaire, and dietary quality was assessed using a 24-hour dietary recall as a dietary diversity score. Data on annual medical use and expenditures from the interview date until December 31, 2006, were collected from National Health Insurance claims. Generalized linear models were used to assess the associations between chewing ability, dietary quality, and annual medical usage or expenditure. After 8 years of follow-up, older adults with unsatisfactory chewing ability had considerably higher emergency, hospitalization, and total medical expenditures. Older adults with unsatisfactory chewing ability and a poor diet used fewer annual preventive care and dental services than those with satisfactory chewing ability but had longer hospital stays and higher expenditures. After adjusting for covariates, unsatisfactory chewing ability resulted in significantly longer hospital stays in participants with a poor diet (β = 2.34, 95% confidence interval = 2.02-2.71, P chewing ability and a less-diverse diet together are associated with longer hospital stays and higher medical expenditures. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

‘And God gave Solomon wisdom’: Proficiency in ornithomancy

Directory of Open Access Journals (Sweden)

Abraham O. Shemesh

2018-04-01

Full Text Available The biblical text accords a great deal of attention to King Solomon’s personal abilities and governmental power. Solomon was described as a judge, poet, constructor and the wisest of all people in the Ancient Near East and Egypt. The current study discusses the interpretation of the midrashim that show how Solomon’s wisdom was manifested in his considerable knowledge of ornithomancy, that is, divination using birds, a practice that was considered as an important wisdom in the ancient world because of its practical applications, particularly in the military sphere. It seems that Solomon’s portrayal as a magician is intended and aimed at emphasising his abilities and his impressive character. Moreover, it may have had the purpose of disproving the conception of Solomon as inferior to his surroundings in this respect and the idea that he or his kingdom could be controlled by nations that command this type of wisdom.

An assessment of the microbiological quality of liver-based pâté in England 2012-13: comparison of samples collected at retail and from catering businesses.

2017-06-01

The purpose of this study was to investigate the microbiological quality of liver pâté. During 2012-13, a total of 870 samples, unrelated to the investigation of food-poisoning outbreaks, were collected either at retail (46%), catering (53%) or the point of manufacture (1%) and were tested using standard methods to detect Salmonella spp. or Campylobacter spp., and to enumerate for Listeria spp., including Listeria monocytogenes, Clostridium perfringens, coagulase-positive staphylococci including Staphylococcus aureus, Bacillus spp., including Bacillus cereus, Escherichia coli, Enterobacteriaceae, and aerobic colony counts (ACCs). Seventy-three percent of samples were of satisfactory microbiological quality, 18% were borderline and 9% unsatisfactory. Salmonella spp. or Campylobacter spp. was not recovered from any sample. The most common causes of unsatisfactory results were elevated ACCs (6% of the samples) and high Enterobacteriaceae counts (4% of samples). The remaining unsatisfactory results were due to elevated counts of: E. coli (three samples); B. cereus (one sample at 2·6 × 105 cfu/g); or L. monocytogenes (one sample at 2·9 × 103 cfu/g). Pâté from retail was less likely to be contaminated with L. monocytogenes than samples collected from catering and samples from supermarkets were of significantly better microbiological quality than those from catering establishments.

Quality of courses evaluated by 'predictions' rather than opinions: Fewer respondents needed for similar results.

Science.gov (United States)

Cohen-Schotanus, Janke; Schönrock-Adema, Johanna; Schmidt, Henk G

2010-01-01

A well-known problem with student surveys is a too low response rate. Experiences with predicting electoral outcomes, which required much smaller sample sizes, inspired us to adopt a similar approach to course evaluation. We expected that having respondents estimate the average opinions of their peers required fewer respondents for comparable outcomes than giving own opinions. Two course evaluation studies were performed among successive first-year medical students (N = 380 and 450, respectively). Study 1: Half the cohort gave opinions on nine questions, while the other half predicted the average outcomes. A prize was offered for the three best predictions (motivational remedy). Study 2: Half the cohort gave opinions, a quarter made predictions without a prize and a quarter made predictions with previous year's results as prior knowledge (cognitive remedy). The numbers of respondents required for stable outcomes were determined following an iterative process. Differences between numbers of respondents required and between average scores were analysed with ANOVA. In both studies, the prediction conditions required significantly fewer respondents (p < 0.001) for comparable outcomes. The informed prediction condition required the fewest respondents (N < 20). Problems with response rates can be reduced by asking respondents to predict evaluation outcomes rather than giving opinions.

Tricuspid valve insufficiency (TI) following cardiovascular surgery causes right-side heart failure and hepatic failure, which affect patient prognosis. Moreover, the benefits of reoperation for severe tricuspid insufficiency remain unclear. We investigated the surgical outcomes of reoperation in TI. From the Japan Cardiovascular Surgery Database (JACVSD), we extracted cases who underwent surgery for TI following cardiac surgery between January 2006 and December 2011. We analysed the surgical outcomes, specifically comparing tricuspid valve replacement (TVR) and tricuspid valve plasty (TVP). Of the 167 722 surgical JACVSD registered cases, reoperative TI surgery occurred in 1771 cases, with 193 TVR cases and 1578 TVP cases. The age and sex distribution was 684 males and 1087 females, with an average age of 66.5 ± 10.8 years. The overall hospital mortality was 6.8% and was significantly higher in the TVR group than in the TVP group (14.5 vs 5.8%, respectively; P tricuspid surgery were unsatisfactory. Although TVR is a last resort for non-repairable tricuspid lesions, it carries a significant risk of surgical mortality. Improving the patient's preoperative status and opting for TVP over TVR is necessary to improve the results of reoperative tricuspid surgery. © The Author 2014.

Non-local energy density functionals: models plus some exact general results

International Nuclear Information System (INIS)

March, N.H.

2001-02-01

Holas and March (Phys. Rev. A51, 2040, 1995) gave a formally exact expression for the force - δV xc (r-tilde)/δr-tilde associated with the exchange-correlation potential V xc (r-tilde) of density functional theory. This forged a precise link between first- and second-order density matrices and V xc (r-tilde). Here models are presented in which these low-order matrices can be related to the ground-state electron density. This allows non-local energy density functionals to be constructed within the framework of such models. Finally, results emerging from these models have led to the derivation of some exact 'nuclear cusp' relations for exchange and correlation energy densities in molecules, clusters and condensed phases.

The follow-up data on 39 cases of stage I malignant melanoma treated with CO 2 laser are compared to those of an analogous group of cases treated by traditional surgical methods and selected for their clinical and pathologic similarities with the laser-treated group. The findings ware expressed in terms of tumor-free time and were evaluated by variance analysis. The data showed that traditional methods gave better results. CO 2 laser surgery requires longer headling time, which may have a negative effect on the course of the disease

Objective: To evaluate the knowledge of HIV/AIDS among gypsies in Lahore and their preventive practices Study Design: Cross-sectional study. Place and Duration of Study: Four gypsy settlements around Multan Road, Lahore were surveyed from July to August 2009. Methodology: Two hundred and thirteen randomly selected gypsies, aged 15-50 years, were interviewed using a pretested questionnaire based on UNAIDS survey indicators. Socio-demographic information and knowledge about HIV/AIDS, its spread and preventive practices was asked. Scoring systems were devised to categorize the level of knowledge and preventive practices as satisfactory and unsatisfactory. Statistically significant difference between knowledge and preventive practices was calculated by Pearson's chi-square test using Epi Info. version 3.5.1. Results: The mean age of participants was 29.5 +- 6.5 years, including 60.2% males and 39.8% females. Aggregate score for the level of knowledge indicated that 17 (7.98%) of these gypsies had satisfactory knowledge about HIV/AIDS and its transmission, whereas 40 (18.77%) and 156 (73.23%) were classified as having unsatisfactory and poor knowledge respectively. However, there was a statistically significant difference (p=0.003) when this knowledge was compared with preventive practices. Conclusion: Knowledge of HIV/AIDS among gypsies in Lahore was largely unsatisfactory. Improving knowledge about HIV/AIDS among gypsy community may result in positive behavioural change for disease prevention. (author)

1999-12-01

The Netherlands agency for energy and the environment (Novem) commissioned a consortium to carry out the ABC (Dutch abbreviation for Waste and Biomass Conversion) project in three separate studies: (A) a scenario study of the availability of biomass and waste for energy generation in the Netherlands; (B) a 'three-level assessment' of biomass availability on national, European and global levels; and (C) a scenario study of the feasibility / profitability of energy crops in the Netherlands. The results of the ABC project are published in two separate reports. This present report gives the results of the combined scenario study of availability (A) and the three-level assessment (B). The results of the energy crops study (C) are presented elsewhere. The goal of the present project is to gain insight into the current availability of biomass and waste flows for energy generation, and of the driving forces and constraints that can affect their availability up to the year 2020. First, it is examined whether the availability of biomass and waste is or could become problematic. This is an important aspect for market parties that want to invest in energy from biomass and biomass. Second, it is examined what additional policy measures the Dutch government would need to take to achieve the set policy goal of savings of fossil fuels. The combined scenario study of waste availability (in the Netherlands) and biomass availability (in the Netherlands, the European Union, and worldwide) for energy generation started off with a Definition Phase. In this phase, the project's framework and key issues were formulated and relevant sources of information were outlined. On the basis of these sources, a Quick Scan was carried out to map the existing information as well as any gaps in knowledge and uncertainties about the availability of biomass and waste. In the subsequent In-depth Phase the results of the Quick Scan were submitted to a number of national experts for comment

Some results of applied interspecific hybridization in sunflower breeding

Tsvetkova, F.

1976-01-01

Investigations on the interspecific hybridization in sunflower, aimed at developing a diversified initial selection material, were carried out Wild species of the diploid, tetraploid and hexaploid groups, varieties, hybrids, and selfed-lines of cultivated sunflower were used for crossings. To overcome incrossability between the species and sterility in the hybrids the method of f;cilitating of crossability by mutual gra'fting and gamma-rays treatment of seeds and pollen were applied. Results showed that: 1. By the method of interspecific hybridization forms might be produced resistant to more important diseases. 2. Interspecific hybridization in combination with other methods of selection might produce varieties and hybrids with a complex of valuable qualities. 3. Crossings between wild species and cultivated sunflower gave progenies with gene rale sterility. 4. The species H.tuberosus, H.scaberimus, H.arωphylus and H.lenticularis possess genes of full fertility restoration. (author)

Assisted reproduction is traditionally regarded as effective when it results in a high pregnancy rate per started treatment cycle. For the patients, it is more interesting to know how high the probability is of giving birth during a full course of assisted reproduction treatment. Retrospective series of 546 patients followed for three years of assisted reproduction at a public fertility clinic. During the follow-up period, 347 of the patients (63.6%) gave birth by means of assisted reproduction. Of the 199 remaining patients, 70 (12.8% of 546) stopped treatment because they had completed the three treatment cycles that are covered by public funding. Thirty seven patients (6.8% of 546) conceived without assisted reproduction. Assisted reproduction at public fertility clinics in Norway is as effective as that in our neighbouring countries. Over the past 18 years, the effectiveness of assisted reproduction has increased by about 50%.

EUROASPIRE (European Action on Secondary Prevention through Intervention to Reduce Events) III--a comparison of Irish and European results.

LENUS (Irish Health Repository)

2009-04-01

The EUROASPIRE III audit was a Europe-wide study which took place in 2006\\/2007. The objective was to examine the control of risk factors in subjects with established cardiovascular disease. Here, we compare the Irish results to those of the other 21 European countries which participated. Control of blood cholesterol was significantly better in Irish participants, with 73% below the target of 4.5 mmol\\/l. Blood pressure control was less satisfactory in both Irish and European individuals, with an average of 52% of Irish participants not achieving blood pressure targets. Medication usage was high throughout, particularly anti-platelet agents, beta-blockers and, especially in Ireland, statins. Obesity figures were particularly high in Ireland and throughout Europe, with 82% Irish men and women either overweight or obese. Smoking figures in Irish women were also of concern, with 24% continuing to smoke. Cardiac rehabilitation attendance was particularly high in Ireland, with 68% attending; substantially higher than the European figure of 34%. In common with the rest of Europe, current control of body weight and blood pressure in Ireland is unsatisfactory and in need of increased consideration on the part of both patients and healthcare professionals.

European external quality control study on the competence of laboratories to recognize rare sequence variants resulting in unusual genotyping results.

Science.gov (United States)

Márki-Zay, János; Klein, Christoph L; Gancberg, David; Schimmel, Heinz G; Dux, László

2009-04-01

Depending on the method used, rare sequence variants adjacent to the single nucleotide polymorphism (SNP) of interest may cause unusual or erroneous genotyping results. Because such rare variants are known for many genes commonly tested in diagnostic laboratories, we organized a proficiency study to assess their influence on the accuracy of reported laboratory results. Four external quality control materials were processed and sent to 283 laboratories through 3 EQA organizers for analysis of the prothrombin 20210G>A mutation. Two of these quality control materials contained sequence variants introduced by site-directed mutagenesis. One hundred eighty-nine laboratories participated in the study. When samples gave a usual result with the method applied, the error rate was 5.1%. Detailed analysis showed that more than 70% of the failures were reported from only 9 laboratories. Allele-specific amplification-based PCR had a much higher error rate than other methods (18.3% vs 2.9%). The variants 20209C>T and [20175T>G; 20179_20180delAC] resulted in unusual genotyping results in 67 and 85 laboratories, respectively. Eighty-three (54.6%) of these unusual results were not recognized, 32 (21.1%) were attributed to technical issues, and only 37 (24.3%) were recognized as another sequence variant. Our findings revealed that some of the participating laboratories were not able to recognize and correctly interpret unusual genotyping results caused by rare SNPs. Our study indicates that the majority of the failures could be avoided by improved training and careful selection and validation of the methods applied.

A comparison of two different T-grain films in rare-earth screens with a standard film-screen combination for intravenous pyelography and bone examinations

International Nuclear Information System (INIS)

Logan, H.; Daly, L.; Masterson, J.

1989-01-01

T-grain film is claimed to give significantly improved image quality, allowing use of faster screens without loss of quality, thus reducing radiation dose. We tested this claim for two systems. In each case comparison was made with our usual screen-film combination, Agfa Curix RP1 film with Kodak Xomatic Regular screens (a nominally 200 speed system). The systems tested were Kodak TMatG in Kodak Lanex Medium screens (300 speed) and Agfa STG in Kodak Lanex Regular screens (400 speed). The Agfa STG-Lanex Regular system performed less well than the standard system for intravenous pyelograms (IVPs), bones and soft-tissue detail. Its speed advantage was not apparent below 70 kV. The Kodak TMatG-Lanex Medium system was better than the standard system for IVPs but not as good for bones. It gave virtually no speed advantage below 90 kV. Kodak T-grain film in a medium-speed, rare-earth screen was found to be better than the standard system for IVPs. Agfa T-grain film in a fast rare-earth screen was unsatisfactory for IVPs. Neither combination was as good as the standard system for bones. (author)

India and Iran's nuclear issue: the three policy determinants

International Nuclear Information System (INIS)

Rajiv, S. Samuel C.

2011-01-01

Three broad policy determinants can be discerned in Indian reactions to the Iranian nuclear issue. These include: 'strategic autonomy' as it relates to Indian foreign policy decision making; concerns regarding 'regional strategic stability' as it relates to events in its 'proximate neighbourhood'; and 'national security' implications on account of operative clandestine proliferation networks. Issues relating to the role of the US in influencing Indian policy positions at international forums and vis-a-vis domestic policy were prominent as regards the first determinant. Threats and 'advice' by American policy makers and law makers on specific issues like the Indo-US nuclear deal and the Iran-Pakistan-India gas pipeline gave further grist to critics. However, an analysis of India's concerns regarding the other two policy considerations, i.e., strategic stability and national security were 'real and present' and also dominated public discourse as well. With India having become a non-permanent member of the UN Security Council from January 2011, it should be the task of Indian diplomacy, at the UNSC as well as at other bilateral and multilateral settings, to help expand the space for the application of 'satisfactory strategies' and reduce the range of 'unsatisfactory strategies'.

Osterwald, C.R.; Emery, K. [National Renewable Energy Lab., Golden, CO (United States); Anevsky, S. [All-Union Research Inst. for Optophysical Measurements, Moscow (Russian Federation)] [and others

1996-05-01

This paper presents the results of an international intercomparison of photovoltaic (PV) performance measurements and calibrations. The intercomparison, which was organized and operated by a group of experts representing national laboratories from across the globe (i.e., the authors of this paper), was accomplished by circulating two sample sets. One set consisted of twenty silicon reference cells that would, hopefully, form the basis of an international PV reference scale. A qualification procedure applied to the calibration results gave average calibration numbers with an overall standard deviation of less than 2% for the entire set. The second set was assembled from a wide range of newer technologies that present unique problems for PV measurements. As might be expected, these results showed much larger differences among laboratories. Methods were then identified that should be used to measure such devices, along with problems to avoid.

Full Text Available OBJECTIVE: To determine indications for circumcision revision and to identify the specialty of the person who performed unsatisfactory primary circumcision. MATERIALS AND METHODS: The authors reviewed medical records of 52 cases that underwent circumcision revision over a 6-year period (1998 to 2004. Sleeve surgical technique was used for revision in patients with redundant foreskin or concealed penis, penoplasty for partial or complete degloving of the penis and meatotomy for external meatal stenosis. The mean age of children was 32 months (range 6 months to 9 years. RESULTS: Most of unsatisfactory primary circumcisions (86.7% were performed by laymen. All patients who underwent circumcision revision had good to excellent cosmetic results. CONCLUSION: Primary circumcision performed by laymen carry a high complication rate and serious complications may occur. A period of training and direct supervision by physicians is required before allowing laymen to perform circumcision independently.

The eosin-5'-maleimide (EMA) Binding test measures reduced mean channel fluorescence (MCF) reading of EMA-labeled red cells (EMA-RBCs) from patients with hereditary spherocytosis (HS). Reporting test results can be either in the actual MCF reading or as a ratio by normalization of the test MCF result to the mean MCF value of six normal controls. The latter format has potential for universal reporting. We analyzed three years' archival MCF data from HS and non-HS patient groups for establishment of reference ranges of ratios for normal adults and HS. A prospective study used FC500 and FACS Canto II cytometers to analyze contemporaneously EMA-RBCs from several patient groups and normal donors. Statistical analyses of the prospective data determined the cut-off values, and the sensitivity and specificity for HS respectively for the MCF and the ratio result presentations. The effect of using fewer than six normal controls for the ratio denominator was explored. The FC500 gave a mean ratio of 0.782 (SD=0.086) in HS patients with an optimal cut-off ratio of 0.918 (98.7% specificity, 95.6% sensitivity), and gray area ratio of 0.868-0.918. The Canto II gave a mean ratio of 0.774 (SD=0.085) with an optimal cut-off ratio of 0.925 (97.1% specificity and 100% sensitivity), and gray area ratio of 0.859-0.925. Harmonization of result presentation is feasible with no apparent constraint by instrument design. Interpretation of gray-area data requires an assessment of patient's clinical presentation and family history or performing a family study. © 2014 Clinical Cytometry Society.

Full Text Available Aim: Find the periodontal treatment that best maintained clinical results over time evaluated by changes in pocket depth (PD and clinical attachment level (CAL. Methods: 229 patients with chronic periodontitis from USA (n=134 and Sweden (n=95 were randomly assigned to eight groups receiving 1 scaling+root planing (SRP alone or combined with 2 surgery (SURG+systemic amoxicillin (AMOX+systemic metronidazole (MET; 3 SURG+local tetracycline (TET; 4 SURG; 5 AMOX+MET+TET; 6 AMOX+MET; 7 TET; and 8 SURG+AMOX+MET+TET. Antibiotics were given immediately after SRP. Plaque, gingival redness, bleeding on probing, suppuration, PD, and CAL were recorded at baseline and after 3, 6, 12, 18, and 24 months. Treatment effects were evaluated by linear multilevel regression and logistic multilevel regression models. We considered only data from sites with a baseline PD of at least 5 mm of 187 patients completing the study. Results: Surgically treated patients experienced most CAL loss. Adjunctive therapy including SURG was most effective in reducing PD. Combining SURG with AMOX, MET, and TET gave significant clinical benefits. Past and current smoking habits were significant predictors of deeper PD. Only current smoking was a significant predictor of CAL loss. Bleeding, accumulation of plaque, gingival redness, and suppuration were significant predictors of further CAL loss and deeper PD. Conclusions: Both surgical and non-surgical therapies can be used to arrest chronic periodontitis. SURG+AMOX+MET+TET gave best maintenance of clinical results.

With the aim of determining the irradiation-induced embrittlement of a base metal and a weld metal in a pressure vessel of the nuclear icebreaker Lenin after 18 years operation the specimens cut out of a vessel wall are used to study the chemical composition and to carry out impact tests. From the test results the temperature dependences of fracture energy are built which define the irradiation embrittlement of a low alloy steel. It is noted that the annealing at 475 deg C for 100 h results in complete restoration of impact strength. Based on the results obtained the following conclusions are formulated: a reactor vessel base metal has high resistance to brittle fracture and high radiation resistance; a weld metal possesses rather high radiation resistance but unsatisfactory ductile-brittle transition temperature (∼ 63 deg C); for cladded vessels there is a potential reserve in the form of enhanced radiation resistance of an undercladding layer; in the final stage of operation the coolant temperature is recommended to be kept at the highest possible level [ru

Overactive bladder – 18 years – Part II

Directory of Open Access Journals (Sweden)

Jose Carlos Truzzi

2016-04-01

Full Text Available ABSTRACT Traditionally, the treatment of overactive bladder syndrome has been based on the use of oral medications with the purpose of reestablishing the detrusor stability. The recent better understanding of the urothelial physiology fostered conceptual changes, and the oral anticholinergics – pillars of the overactive bladder pharmacotherapy – started to be not only recognized for their properties of inhibiting the detrusor contractile activity, but also their action on the bladder afference, and therefore, on the reduction of the symptoms that constitute the syndrome. Beta-adrenergic agonists, which were recently added to the list of drugs for the treatment of overactive bladder, still wait for a definitive positioning – as either a second-line therapy or an adjuvant to oral anticholinergics. Conservative treatment failure, whether due to unsatisfactory results or the presence of adverse side effects, define it as refractory overactive bladder. In this context, the intravesical injection of botulinum toxin type A emerged as an effective option for the existing gap between the primary measures and more complex procedures such as bladder augmentation. Sacral neuromodulation, described three decades ago, had its indication reinforced in this overactive bladder era. Likewise, the electric stimulation of the tibial nerve is now a minimally invasive alternative to treat those with refractory overactive bladder. The results of the systematic literature review on the oral pharmacological treatment and the treatment of refractory overactive bladder gave rise to this second part of the review article Overactive Bladder – 18 years, prepared during the 1st Latin-American Consultation on Overactive Bladder.

Management effectiveness evaluation in protected areas of southern Ecuador.

Protected areas are home to biodiversity, habitats and ecosystem as well as a critical component of human well-being and a generator of leisure-related revenues. However, management is sometimes unsatisfactory and requires new ways of evaluation. Management effectiveness of 36 protected areas in southern Ecuador have been assessed. The protected areas belong to three categories: Heritage of Natural Areas of the Ecuadorian State (PANE), created and funded by the State, Areas of Forest and Protective Vegetation (ABVP), created but no funded by the State, and private reserves, declared and funded by private entities. Management effectiveness was evaluated by answers of managers of the protected areas to questionnaires adapted to the socio-economic and environmental characteristics of the region. Questions were classified into six elements of evaluation: context, planning, inputs, processes, outputs and outcomes as recommended by IUCN. Results were classified into four levels: unsatisfactory, slightly satisfactory, satisfactory and very satisfactory. The PANE areas and private reserves showed higher management effectiveness levels (satisfactory and very satisfactory) than ABVP areas, where slightly satisfactory and unsatisfactory levels prevailed. Resources availability was found as the main reason behind this difference. The extension, age and province of location were found irrelevant. Outputs, inputs and processes require main efforts to improve management effectiveness. Improving planning and input in the PANE areas and inputs and outcomes on ABVP areas is necessary to obtain a similar result in all areas. Copyright © 2016 Elsevier Ltd. All rights reserved.

Free-Spinning and Recovery Characteristics of a 1/19-Scale Model of the North American T-28C Airplane, TED No. NACA AD 3127

Bowman, James S., Jr.

1956-01-01

An investigation has been conducted in the Langley 20-foot free-spinning tunnel on a l/19-scale model of the North American T-28C airplane to determine the spin and recovery characteristics. The T-28C airplane is similar to the T-28B airplane except for slight modifications for the arresting hook. The lower rear section of the fuselage was cut out and, consequently, the lower part of the rudder was removed to make a smooth fairing with the fuselage. The T-28B airplane had good recovery characteristics; but these modifications, along with the addition of gun packages on the wings, led to poor and unsatisfactory spin-recovery characteristics during demonstration spins of the T-28C airplane. Model test results indicated that without the gun packages installed, satisfactory recoveries could be obtained if the elevators were held full back while the rudder was fully reversed and the ailerons were held neutral. However, with the addition of gun packages to the wings and the corresponding change in loading, recoveries were considered unsatisfactory. Recoveries attempted by using a larger chord or larger span rudder were improved very slightly, but were still considered marginal or unsatisfactory. Strakes placed on the nose of the model were effective in slowing the spin rotation slightly and, in most instances, decreased the turns for recovery slightly. Recovery characteristics were slightly marginal for the full fuel loading when strakes and the extended-chord rudder were installed; but with the wing fuel partly used, recovery characteristics were again considered unsatisfactory or, at least, definitely on the marginal side. The optimum control technique for recovery is movement of the rudder to full against the spin with the stick held full back (elevators full up) and the ailerons held neutral, followed by forward movement of the stick only after the spin rotation ceases. Inverted-spin test results indicate that the airplane will spin steep and fast and that recovery

A classification is made of wells according to the complexity of separation of the beds. Five categories are isolated. The criterion for comparing the categories was the presence or absence in the productive part of the section of water-bearing levels and screening beds. In a number of cases, as a result of unsatisfactory sedimentation stability of the cementing fluid, channels can be formed in it which may be the reason for transcolumn overflows and interruption in the removal of pure (not containing water) oil. In order to control transcolumn overflows in wells of the II-III-IV category, packer-filters (PFM) are used whose action is based on the forced recovery from the cement fluid of part of the liquid phase. The use of PFM is recommended only after conducting of a set of special (laboratory, geophysical, geological-technical, ect.) studies. The possibility is shown of positive use of PFM not only in the well shafts of nominal diameter, but also in wells prone to cavern formation. In the example of well No 13993 of the Abdrakhmanovskiy field, the possibility is shown of sectioning the PFM. Based on the PFM, and PFU was created with elongated filtering part. The results of introducing the PFU and the PFM are positive, and the economic effect from using the PFU is 1.5-fold greater than from PFM. In addition to PFU and PFM, the wells of the association ''Tatneft''' have used packers of the type PPG designed by the All-Union Scientific Research of Drilling Equipment. The results of introducing the packers PPG are positive.

The Banff classification was introduced to achieve uniformity in the assessment of renal allograft biopsies. The primary aim of this study was to evaluate the impact of specimen adequacy on the Banff classification. All renal allograft biopsies obtained between July 2010 and June 2012 for suspicion of acute rejection were included. Pre-biopsy clinical data on suspected diagnosis and time from renal transplantation were provided to a nephropathologist who was blinded to the original pathological report. Second pathological readings were compared with the original to assess agreement stratified by specimen adequacy. Cohen's kappa test and Fisher's exact test were used for statistical analyses. Forty-nine specimens were reviewed. Among these specimens, 81.6% were classified as adequate, 6.12% as minimal, and 12.24% as unsatisfactory. The agreement analysis among the first and second readings revealed a kappa value of 0.97. Full agreement between readings was found in 75% of the adequate specimens, 66.7 and 50% for minimal and unsatisfactory specimens, respectively. There was no agreement between readings in 5% of the adequate specimens and 16.7% of the unsatisfactory specimens. For the entire sample full agreement was found in 71.4%, partial agreement in 20.4% and no agreement in 8.2% of the specimens. Statistical analysis using Fisher's exact test yielded a P value above 0.25 showing that - probably due to small sample size - the results were not statistically significant. Specimen adequacy may be a determinant of a diagnostic agreement in renal allograft specimen assessment. While additional studies including larger case numbers are required to further delineate the impact of specimen adequacy on the reliability of histopathological assessments, specimen quality must be considered during clinical decision making while dealing with biopsy reports based on minimal or unsatisfactory specimens.

Risk-perception and dangerous driving among adolescents: Outcome- and behavior-focused questions yield opposite results.

Science.gov (United States)

O'Brien, Fearghal; Gormley, Michael

2016-10-01

While some studies have found that those who perceive a behavior to be more risky are less likely to engage in it, others have found that those who engage in more risky behaviors see themselves as being more at-risk. Using an online questionnaire we investigated whether such conflicting findings may be due to the types of risk-questions employed in past studies. We assessed risk-perception using outcome-focused questions (e.g. the likelihood of being in an accident) and a behavior-focused question (the riskiness of speeding). Participants who reported engaging in more risky driving gave higher estimates of their chances of experiencing a negative outcome. However, those same participants gave lower estimates of the general riskiness of risky driving. Drivers may think about the risks of risky driving in different ways depending on the focus of the questions. Published by Elsevier Ltd.

The Intergovernmental Panel on Climate Change gave a methodology to estimate the methane emissions from Municipal Solid Wastes landfills, based on a First Order Decay (FOD) model that assumes biodegradation kinetics depending on the type of wastes. This model can be used to estimate both the National greenhouse gas emissions in the industrialized countries as well as the reductions of these emissions in the developing ones when the Clean Development Mechanism, as defined by the Kyoto Protocol, is implemented. In this paper, the FOD model has been use to evaluate the biogas flow rates emitted by a Brazilian landfill and the results have been compared to the extracted ones: some first results can be useful to evidence the weight of key parameters and do a correct use of the model. - Highlights: ► Landfill biogas is greenhouse gas and fuel at the same time. ► In developing countries its collection can implement Kyoto Protocol mechanisms. ► Biogas collection and exploiting become part of energy policy. ► Project economical balance is based on reliable estimates of generated quantities.

[Endoscopic calcaneoplasty (ECP) in Haglund's syndrome. Indication, surgical technique, surgical findings and results].

Posterior calcaneal exostosis treatment modalities have given rise to many controversial opinions. After failure of the conservative treatment, surgical bursectomy and resection of the calcaneal exostosis are indicated by many authors. But clinical studies also show a high rate of unsatisfactory results with a relative high incidence of complications. The minimally invasive surgical technique by an endoscopic calcaneoplasty (ECP) could be an option to overcome some of these problems. Between 1999 und 2010 we operated 164 patients with an age range between 16 and 67 years, 81 males and 83 females. The radiological examination prior to surgery documented in all cases a posterior superior calcaneal exostosis that showed friction to the Achilles tendon. All patients included in the study had no clinical varus of the hind foot, nor cavus deformities. All patients had undergone a trial of conservative treatment for at least 6 months and did not show a positive response. The average follow-up was 46.3 (range: 8-120) months. According to the Ogilvie-Harris score 71 patients presented good and 84 patients excellent results, while 5 patients showed fair results, and 4 patients only poor results. All the post-operative radiographs showed sufficient resection of the calcaneal spur. In 61 patients the preoperative MRI showed a partial rupture of the Achilles tendon close to the insertion side. In no case could we observe a complete tear at the time of follow-up. Only minor postoperative complications were observed. In many patients we could observe a chondral layer at the posterior aspect of the calcaneus. Close to the intersion the Achilles tendon showed also in many patients a chondroide metaplasia. ECP is an effective and minimally invasive procedure for the treatment of patients with calcaneal exostosis. After a short learning curve the endoscopic exposure is superior to the open technique, has less morbidity, less operating time, and nearly no complications. Moreover, the

Liljenzin, J.O.; Persson, G.

1981-01-01

The CTH actinide separation process has been tested by treating 16 l of 10 year old waste solution from PUREX reprocessing of metallic fuel. It was in general found to operate well and, in some respects, slightly better than design specifications. The extraction process removed more than 99.995% of initial alpha activity. After the sorption steps 5 Bq/l β-activity remained in solution. The modified reversed TALSPEAK process used to separate Am and Cm from the lanthanides gave an Am-Cm product with less than 0.7% of the lanthanides and vice versa. This result can probably be somewhat improved by continuous addition of lactic acid and closer pH control. (orig.)

Full Text Available The paper focuses on the results of physiological research performed on 9 occupational groups of migrants who came to Moscow region of Russia from southern Central Asia republics. We studied adaptation processes characteristics in labor migrants as per cardiovascular system parameters and neuromuscular apparatus parameters. We revealed peculiarities in heart rate variability (changes in stress index S1, values of AMo, VLF spectrum power, PARS parameter in migrants de-pending on neuro-emotional nature of working activity and muscular loads intensity. We detected apparent decrease in dynamometric parameters of endurance and maximum working capacity of arms muscles and backbones and legs muscles by the end of their working day. We created a procedure to determine an adaptation process stage under combined effects ex-erted by labor physical hardness and neuro-emotional intensity; unsatisfactory adaptation increases health disorders risks. We showed that long-term and intense impacts by factors determining labor process hardness caused occupational diseases of musculoskeletal system and peripheral nervous system. We revealed that as labor intensity grew working stress in a body also increased and it could transform into overstrain and occupational diseases evolvement (primary hypertension, ischemic heart diseases, and neurotic disorders. A distinctive feature is that men suffer from cardiovascular system pathologies more frequently while women tend to suffer from nervous system pathologies. In this relation, we should make separate predictions of occupational pathology probability depending on labor intensity level for males and females. Adaptation processes optimization should include organization of rational work and rest regime, healthy lifestyle for-mation, improvements in medical aid for migrants.

Szymczyk, W.; Radziszewska, J.; Cyplik, I.; Glinska, H.

1985-01-01

Three-year results of X-ray therapy of skin cancer in 345 patients are presented. The dependence of results on the size of irradiated field and the method of dose fractionation is analysed. The clinical usefulness of a cumulative radiation effect (CRE) is evaluated. 96.5% of three-year cures were obtained. Recurrences amounted to 1.6% and necroses to 1.9% of treated lesions. It has been shown that treatment of small fields with 8-fractions gave equally positive results as with 15-fractions whereas in the treatment of large lesions the selection of CRE value, a number of fractions and dose should let the value of CRE minimally exceeds the level of tolerance of healthy tissues. The regard to CRE value in the treatment of large lesions or the introduction of additional dosimetric acts seems to be useful. 10 refs., 1 fig., 5 tabs. (author)

New results on CP violation in the charm sector

CERN Multimedia

CERN. Geneva

2013-01-01

The difference in CP violation between the D0→K+K– and D0→π+π– decays (ΔACP) has emerged as an interesting observable to search for matter-antimatter asymmetries in the charm sector. By taking the difference between the two modes, most of the asymmetries induced by the detector or coming from the production mechanism cancel. A previous LHCb measurement, using 0.6 fb–1 of data, gave 3.5σ evidence for CP violation in the charm sector, which was further strengthened by results from the CDF and Belle collaborations. We present an update of the ΔACP measurement, consisting of two independent analyses, both using the full 2011 data set of 1.0 fb–1. In the first, the initial flavour of the D meson (D0 or D0-bar) is inferred from the charge of the slow pion in the decay D*+→D0π+, as in the previous publication. The second uses D mesons produced in semileptonic B decays, where the charge of the associated muon provides the tag.

This paper summarizes comparisons between MCNP5 and WIMS-AECL / DRAGON / RFSP calculations and experimental results obtained from the Zero Energy Deuterium (ZED-2) critical facility at AECL Chalk River Laboratories. MCNP5 and WIMS-AECL / DRAGON / RFSP were used to calculate reactivity worths for two reactivity devices, a mechanical zone controller (MZC) and shut-off rod (SOR) in a lattice similar to that of the ACR-1000 R . WIMS-AECL / DRAGON / RFSP was also used to obtain kinetics parameters for a transient based on a rod drop of a ZED-2 standby absorber rod (SAR). ZED-2 experiments were performed using 43-element ACR Low Enriched Uranium (ACR-LEU) fuel bundles with H 2 O- or air-cooled fuel bundles arranged in a 24-cm pitch square lattice. Calculations with MCNP5 gave biases in device worths that were within 0.2 mk of measured values, while WIMS-AECL / DRAGON / RFSP gave values that were within 0.3 mk of measured values. Transient analyses using the CERBERUS module within RFSP yielded a total delayed neutron fraction (β) that was within 4% of the value derived by point kinetics analysis of experimental data. The corresponding delayed photo-neutron fraction (β photo-neutron ) from CERBERUS was within 5% of that derived by point kinetics. This study has helped quantify the agreement between calculation and measurement for codes that are used in the safety analysis of the ACR-1000 reactor. Results demonstrate good agreement in code predictions. (authors)

The two methods gave coherent locations of the injector even if there was a difference of 25% of the SGU height between the vertical locations. Prior to that analysis, the RMS values of the signals were calculated in different frequency bands. The results obtained in the 200-1000 Hz were used to draw a rough estimation of the beginnings of the injections in order to determine the parts of the records on which the location signal processing can be carried out.

Maxillary distraction osteogenesis has become an accepted alternative method in the treatment of patients with severe maxillary hypoplasia in craniofacial syndromes and cleft-related deformities. Insufficient distraction, undesirable soft tissue changes, and occurrence of defective distraction vectors are among the potential complications of intraoral maxillary distraction osteogenesis. A 2-stage procedure combining maxillary advancement by distraction technique with genioplasty and mandibular setback surgery was planned to correct jaw deformities in a 22-year-old patient with severe maxillary retrusion, mandibular prognathism, and excessive lower facial height. In the first stage, osteotomies were performed and maxilla was lightly mobilized after down-fracture. Distractors were placed to the maxilla intraorally. During activation period, the maxilla rotated in a clockwise direction, producing a discrepancy between the planned and the actual vectors. Complete distraction was unsatisfactory and the complication was due to surgical technique. This case report presents the failure of maxillary distraction due to incomplete mobilization of the maxilla. Treatment of the case was achieved by the conventional osteotomy techniques at final operation. The maxilla was successfully advanced to the desired position producing good occlusion and an improved facial profile.

Folate assays by use of radiolabeled folate provide obvious practical advantages over the standard microbiological assay, but remain incompletely tested. We therefore compared results for 415 sera with a kit involving 3 H-labeled folate and the Lactobacillus casei microbiological method. We examined the patients' data when there were discrepancies between the two methods. Although the correlation overall was satisfactory, results were discrepant in 25% of cases. In 74% of the latter, the radioassay result appeared to be the correct one, primarily because L. casei results were suppressed by antibiotics being taken by the patient. The radioassay occasionally gave falsely high values for patients with liver disease and falsely low ones for patients who had received isotopes for scanning purposes. Several assay kits that make use of 125 I- or 75 Se-labeled folate were also tested. Although these results correlated with the results of 3 H-labeled folate assay, various problems appeared, including the possible need for serum-supernate control tubes in one kit. Answers to these and other questions and careful clinical correlation of results are needed for any folate radioassays before their adoption for routine clinical use

Full Text Available Aim. To evaluate the results of a modified technique for extra-articular arthrodesis of the subtalar joint for patients with cerebral palsy with an ambulatory form of equine-planovalgus deformity of the foot. The mistakes and complications that occurred during treatment with this technique are discussed. Materials and methods. Between 2005 and 2015, this surgical method for performing arthrodesis of the subtalar joint, was performed on 544 patients (989 feet between 4 and 15 years old. Correction of equinus contracture was performed using Achilles tendon plasty or dissection of the tendon of the gastrocnemius muscle. Abnormal muscle tone was reduced either by administering Dysport® in the calf muscle or by selective neurotomy of the tibial nerve. Results. Good results were achieved for 72% of cases, satisfactory for 23% of cases, and unsatisfactory for 5% of cases. Unsatisfactory results of treatment were associated with overvaluation of the degree of mobility of the deformity and with a number of technical and tactical mistakes. Conclusion. This analysis of mistakes and complications of extra-articular arthrodesis of the subtalar joint will allow surgeons to avoid these issues in the future and improve the quality of treatment for similar patients.

In membrane process industries, membrane cleaning is one of the most important concerns from both economical and scientific points of view. Though cleaning is important to recover membrane performance, an inappropriate selection of cleaning agents may result into unsatisfactory cleaning or irreparable membrane. In this study the cleaning performance has been studied with measurements of membrane contact angle, Updated Donnan steric partitioning pore model (UDSPM) and salt rejection as well as flux measurement. Thin film nanofiltration (NF) membranes such as DK, HL and DL provided by GE Osmonics are used in this study. Tests were carried out with virgin DK, HL and DL as well as fouled DK membranes. Several cleaning agents were investigated; some of them were analytical grade such as HCl, NaOH and others such as SDS, mix agents were commercial grade agents that are already in use in commercial plants. Contact angle, DSPM and salt rejection as well as flux of virgin and fouled membranes before and after chemical cleaning were measured and compared. The contact angle measurements with and without chemical cleaning of different virgin and fouled membranes revealed very interesting results which may be used to characterise the membrane surface cleanliness. The contact angle results revealed that the cleaning agents are found to modify membrane surface properties (hydrophobicity/hydrophilicity) of the treated and untreated virgin and fouled membranes. The details of these results were also investigated and are reported in the paper. However, UDSPM method did not give any valuable information about pore size of the untreated and treated NF membranes. The salt rejection level of monovalent and divalent ions before and after cleaning by high and low pH cleaning agents is also investigated and is reported in the paper

Full Text Available A study of soil erosion rates had been done on a slightly and long slope of cultivated area in Ciawi - Bogor, using 137Cs technique. The objective of the present study was to evaluate the applicability of the 137Cs technique in obtaining spatially distributed information of soil redistribution at small catchment. This paper reports the result of the choice of conversion model for erosion rate estimates and the sensitive of the changes in the model parameter. For this purpose, small site was selected, namely landuse I (LU-I. The top of a slope was chosen as a reference site. The erosion/deposit rate of individual sampling points was estimated using the conversion models, namely Proportional Model (PM, Mass Balance Model 1 (MBM1 and Mass Balance Model 2 (MBM2. A comparison of the conversion models showed that the lowest value is obtained by the PM. The MBM1 gave values closer to MBM2, but MBM2 gave a reliable values. In this study, a sensitivity analysis suggest that the conversion models are sensitive to changes in parameters that depend on the site conditions, but insensitive to changes in  parameters that interact to the onset of 137Cs fallout input.   Keywords: soil erosion, environmental radioisotope, cesium

One hundred and eighty-six carefully selected sera were tested for rubella-specific IgM by Rubazyme-M (Abbott Diagnostics) and an M-antibody capture radioimmunoassay (MACRIA). Eleven of these sera were from cases of infectious mononucleosis, six of which gave positive results in MACRIA, while one gave a positive result in Rubazyme-M. Of the remaining 175 sera, 158 gave concordant results whilst 17 sera gave discordant results; these 17 were also tested by serum fractionation. Problems were encountered with all assay systems used. It is therefore recommended that the results of all tests for rubella-specific IgM should be interpreted with caution.

Riviere, J.; Barbe, B.; Millard, A.; Koundy, V.

1988-01-01

The prevision of the behavior of the 1/6 scale concrete model under internal pressure was realized by means of two computations, the first one with an infinite soil rigidity, the second one with a soil rigidity equal to 61.26 MPa/m. These two computations, that assumed a perfectly axisymetric structure gave theoretical and experimental results in good agreement, except the raft of which the theoretical uplift was three times higher than the experimental one. The main conclusions of this study are as follow: the soil stiffness has no influence on the ultimate behavior of the model, the dead concrete rigidity decreases the raft uplift in an important way, the model is destroyed because the hoop stress reaches the ultimate strength

To determine the five-year success rates, site or sites of failure, prognostic indicators and lower lip morbidity associated with molar apicectomy using amalgam root-end filling. Multicentre, prospective study. The departments of oral and maxillo-facial surgery in two district general hospitals. One thousand and seven molar apicectomy procedures, combined with amalgam root-end filling were expedited during the period 1974-1995. A five-year review of each operated tooth was carried out or attempted between 1979-2000. Of the 790 (78%) operated molars successfully reviewed at 5 years or later 451 (57%) exhibited 'complete healing' and 39 (5%) 'uncertain healing'. Three hundred (38%) were classified as 'unsatisfactory healing' (failures), and these included 12 which were assumed to be of periodontal origin. Whilst longitudinal root fracture, perforation and/or infection in the furcation, periodontal disease or a non-restorable crown accounted for treatment failure and often the need to remove teeth subsequently, the study probably pointed to the apical ends of the roots rather than the furcation as being the major sites at which 'unsatisfactory healing' occurred. Mandibular first molars attracted the highest 'complete healing' rate (60%) and mandibular second molars the lowest (46%). 'Good' root canal treatment (RCT) at the outset improved the prognosis of a root-end filling (REF) whilst the absence of RCT compromised it. Cystic change pointed to a better prognosis than apical granulomatous change as did a deep compared with a shallow 'bone cuff'. Disease at the furcation suggested a worse prognosis. Teeth which showed 'complete healing' at 1 year had a 75% probability of maintaining this outcome at 5 years. Sensory disturbance of variable duration occurred in the lower lip following 20-21% of mandibular molar procedures. In the majority of cases (79-80%) this had remitted within 3 months. A permanent deficit occurred in 8 patients (1%) where the apicectomy could

The general public not engaged in the nuclear power plant industry have no idea of the color usage in the nuclear control room. So we converted the specific color usage situation into similar but general situations. In questionnaire, we gave subjects the general situation where color coding is applied and alternative colors which were applied to the HF010 guidelines. And we asked the subjects to choose the colors proper to the situation and to rank the colors according to the degree of suitability. Two hundred fifty college students participated in the experiment. The results suggest that we can use any color coding system in the conventional control room and the CRT in the control deck because most people have no special previous color-meaning association but red-emergency relation.

2010-01-01

Full Text Available According to its physical-geographical and socio-economical characteristics, the municipality of Negotin belongs to the territories with favorable tourist potentials. In order to scientifically validate this fact, in this paper tourist valorization has been performed using quantitative-qualitative method, giving attractiveness ranking values, based on which conclusions have been made on the direction and forms of tourist potential. The results obtained from tourist valorization have shown that the hydrographic potential and fauna are rated as good (3, and have the highest general tourist value among natural resources. General values are graded as satisfactory (1.8 and the climate is graded as unsatisfactory (1.2. Valorization of anthropogenic characteristics gave the maximal general value (4 to cultural-historical objects including sacral objects - monasteries and churches and the Rajac pimnice. The Rajac pimnice have an especially high value, as they represent, for us, a unique value that can be considered in diverse ways and adjusted to tourist utilization. Based on the performed tourist valorization it can be noted that the general tourist value of the municipality of Negotin is of regional ranking, though anthropogenic potentials are of national ranking and part of them, as emphasized, are objects that are internationally important. The basic shortcoming is the low road quality leading to places of important tourist value, even though the road network is favorable, and there are also many weaknesses in the receptive tourist base. Improvement of these shortcomings would create a good image of the municipality of Negotin in continental tourism of the Republic of Serbia.

The use of wind energy to produce electricity through wind turbines has spread world-wide. The quantity of electricity produced is affected by numerous factors such as wind speed and direction and turbine design; the aim of this paper is to assess the influence of different blades on the performance of a turbine. This study was performed on a turbine in which the blades have a rotating movement, each around its own axis and around the turbine's axis. Unsteady simulations were carried out with several blade stagger angles and one wind speed and 2 different blade geometries were used for 4 rotational speeds. Results showed that the studied turbine gave better performance than vertical axis wind turbines and that blade sketch, blade speed ratios, and blade stagger angle were important influences on the performance. This study showed that this kind of turbine has the potential to achieve good performance but that further work needs to be done.

To start an interexchange program for quality control in cervical cytology and discuss conceptual criteria for diagnosis. Slides were selected in the archives of the 2 institutes and included cases with unsatisfactory, negative and positive results. Sets of slides were changed between the partners every 3 months. At the end of each year a senior cytopathologist was invited to discuss the major discrepancies found in the study. A total of 1,041 cases were analyzed. Full concordance was obtained in 74.4% (774) of cases and discrepancies in 25.6% (267 cases). Full agreement was achieved in 276 (39%) of 707 cases categorized as negative. In 421 negative cases from laboratory A, this concordance represents 65.5% and 96.5% for laboratory B, which submitted 286 negative cases. The main discordance was the high number of atypical squamous cells of undetermined significance cases: 3.1% for A and 128 (33.2%) for B. Samples with discrepancies related to the quality of the material was another controversial issue: of 16 cases from laboratory A, 6 (37.5%) unsatisfactory cases were the same and 10 (62.5%) different. Laboratory B presented 20 unsatisfactory cases, and 14 (70.0%) had other diagnoses. Low grade squamous intraepithelial lesion and high grade squamous intraepithelial lesion concordance ranged from 75% to 80%, and invasive carcinoma has 4 discordances (28.5%), 3 previously screened as high grade squamous intraepithelial lesion and 1 as atypical squamous cells of undetermined significance. The kappa value obtained was 0.65, indicating substantial agreement. Our results indicated that atypical squamous cells of undetermined significance diagnoses are the crucial point of controversies and concern the quality of routine diagnosis in cytopathology.

The search for an optimal patch material for aortic valve reconstruction (AVR) is an ongoing challenge. In this study, we report our experience of AVR using decellularized bovine pericardial patch material in congenital heart surgery. Data of 40 consecutive patients who underwent AVR using the CardioCel® patch (Admedus Regen Pty Ltd, Perth, WA, Australia) between February 2014 and August 2016 were retrospectively reviewed. The median age of the patients at operation was 9 (2-34) years, and 18 patients were younger than 7 years. Twenty-six patients initially presented with aortic valve insufficiency (AI) and 14 with stenosis. Clinical and echocardiographic data were available until August 2017 for a median postoperative follow-up (FU) of 22 (6-42) months. Nine of 40 (23%) patients experienced an event during FU (death: n = 1, 2.5%; reoperation: n = 8, 20%). Overall, the probability of freedom from reoperation or death was 97 ± 3%, 76 ± 9% and 57 ± 12% at 12, 24 and 36 months of FU, respectively. Reason for reoperation was stenosis in 3 (37.5%) patients, insufficiency in 4 (50%) patients and 1 (12.5%) patient was diagnosed with aortic valve endocarditis. Of the remaining 31 patients, 2 patients are scheduled for reoperation (aortic valve stenosis: n = 1 and AI: n = 1) and 9 patients exhibit worsening of aortic valve function with moderate AI. Freedom from developing combined end point [death/reoperation/moderate degree of aortic valve dysfunction (aortic valve stenosis, AI)] after AVR was 92 ± 5%, 55 ± 9% and 28 ± 9% at 12, 24 and 36 months, respectively. AVR using decellularized bovine pericardial patch material in patients with congenital aortic valve disease show unsatisfactory results within the first 3 years of FU.

To investigate hygiene practices of caterers at large events in order to: support the production of guidance on catering at such events; to compare hygiene standards at weekends with other times in the week; and to learn lessons in preparation for the London Olympics in 2012. UK-wide study of caterers at large events, including questionnaires on hygiene procedures and microbiological examination of food, water and environmental samples. In total, 1364 samples of food, water, surface swabs and cloths were collected at 139 events, by local authority sampling officers, and transported to laboratories for microbiological analysis. Eight percent of food samples were of an unsatisfactory quality, and a further 2% contained potentially hazardous levels of Bacillus spp. A significantly higher proportion of unsatisfactory food samples were taken from vendors without adequate food safety procedures in place. Fifty-two percent of water samples, 38% of swabs and 71% of cloths were also unsatisfactory. The majority of samples (57%) were collected on Saturdays, Sundays or bank holidays. Environmental swab results were significantly poorer at weekends compared with other days of the week. This study reinforces the fact that food hygiene is a continuing cause for concern in mobile vendors, and indicates a need for an ongoing programme of training and monitoring of caterers in preparation for the London Olympics.

The present condition of forest roads as a result of their past maintenance

OpenAIRE

Hribernik, Boštjan; Potočnik, Igor

2006-01-01

Forest roads are built for forest management purposes, to which planning of their use and maintenance is adapted. The increasing importance of non-forestry use of forest roads leads to higher maintenance standard, which by formed maintenance system causes permanent shortage of funds. Higher maintenance costs occur due to the past forest roads construction characteristics, which gave priority to quick opening of villages and farms, on the account of building quality. Other funds expenditure re...

Full Text Available The effectiveness of a learning depends on four main elements, they are content, desired learning outcome, instructional method and the delivery media. The integration of those four elements can be manifested into a learning modul which is called multimedia learning or learning by using multimedia. In learning context by using computer-based multimedia, there are two main things that need to be noticed so that the learning process can run effectively: how the content is presented, and what the learner’s chosen way in accepting and processing the information into a meaningful knowledge. First it is related with the way to visualize the content and how people learn. The second one is related with the learning style of the learner. This research aims to investigate the effect of the type of visualization—static vs animated—on a multimedia computer-based learning, and learning styles—visual vs verbal, towards the students’ capability in applying the concepts, procedures, principles of Java programming. Visualization type act as independent variables, and learning styles of the students act as a moderator variable. Moreover, the instructional strategies followed the Component Display Theory of Merril, and the format of presentation of multimedia followed the Seven Principles of Multimedia Learning of Mayer and Moreno. Learning with the multimedia computer-based learning has been done in the classroom. The subject of this research was the student of STMIK-STIKOM Bali in odd semester 2016-2017 which followed the course of Java programming. The Design experiments used multivariate analysis of variance, MANOVA 2 x 2, with a large sample of 138 students in 4 classes. Based on the results of the analysis, it can be concluded that the animation in multimedia interactive learning gave a positive effect in improving students’ learning outcomes, particularly in the applying the concepts, procedures, and principles of Java programming.

Storey, D; Coward, T J

2013-06-01

The literature is limited in studies directly assessing the quality of impressions for crowns and bridges in the UK. The aim of the study was to assess the quality of impressions for conventional crown and bridgework received by commercial dental laboratories. Three dental laboratories were visited over a 3-month period. All impressions for conventional crowns and bridges that arrived on the days of the visits were examined prior to any laboratory processing. A total of 206 impression cases were examined and assessed against criteria laid out in a custom-designed assessment form. Defects were commonly found in the recording of prepared teeth. Overall, 44.2% of impression cases were unsatisfactory. NHS impressions were more than twice as likely to be unsatisfactory compared to private impressions. If the results of this survey are typical then the general quality of impressions for fixed crown and bridgework is unacceptable. This is particularly true for work completed under the NHS contract.

Extension classification method for low-carbon product cases

Directory of Open Access Journals (Sweden)

Yanwei Zhao

2016-05-01

Full Text Available In product low-carbon design, intelligent decision systems integrated with certain classification algorithms recommend the existing design cases to designers. However, these systems mostly dependent on prior experience, and product designers not only expect to get a satisfactory case from an intelligent system but also hope to achieve assistance in modifying unsatisfactory cases. In this article, we proposed a new categorization method composed of static and dynamic classification based on extension theory. This classification method can be integrated into case-based reasoning system to get accurate classification results and to inform designers of detailed information about unsatisfactory cases. First, we establish the static classification model for cases by dependent function in a hierarchical structure. Then for dynamic classification, we make transformation for cases based on case model, attributes, attribute values, and dependent function, thus cases can take qualitative changes. Finally, the applicability of proposed method is demonstrated through a case study of screw air compressor cases.

The difficulties of Indonesian fourth graders in learning fractions: An early exploration of TIMSS 2015 results

Science.gov (United States)

Wijaya, Ariyadi

2017-08-01

The present study investigates Indonesian fourth-graders low performance in dealing with fractions in TIMSS 2015. Furthermore, the present study also explores possible reasons for this low performance. The data for this study was drawn from TIMSS 2015 data which included test results and responses to Teacher Questionnaire. Descriptive statistics was used to analyze the data. Indonesian textbooks were also analyzed to portrait a broader scope of possible reasons for students' low performance. The analysis of TIMSS test result reveals that Indonesian students, in comparison to students from other countries, had low understanding of the basic concepts of fractions. From the Teacher Questionnaire it was found that a possible reason for this low understanding was the Indonesian curriculum for third grade which gave low emphasis on the basic concepts of fractions and introduced operations of fractions rather early. Furthermore, the result of textbook analysis shows that Indonesian textbooks restricted only to one definition of fractions, i.e. fractions as parts of wholes. This finding might also explain Indonesian fourth graders' low understanding of fractions.

The purpose of this study was to investigate the effect of a biopsy center-a dedicated space with a dedicated ultrasound machine and technologist, staffed daily by a radiologist responsible for performing ultrasound-guided procedures only-on the rate of non-diagnostic or unsatisfactory thyroid fine-needle aspiration (FNA). Three radiologists performed FNA on 1200 nodules in 998 patients between September 2010 and November 2015. We compared rates of nondiagnostic or unsatisfactory FNA before and after implementation of a biopsy center in September 2014 as part of a quality improvement initiative. Before the establishment of our biopsy center, ultrasound-guided procedures were scheduled between diagnostic studies in the main ultrasound department and were performed by a radiologist responsible for both. Multivariate logistic regression analysis was performed to assess the effect of the biopsy center on the odds of obtaining an adequate sample. Rates of nondiagnostic or unsatisfactory FNA decreased significantly from 15.1% to 8.5% (p < 0.001) after implementation of the biopsy center. The odds of obtaining an adequate sample were higher in the biopsy center (odds ratio, 2.07; 95% CI, 1.43-3.01), even after adjusting for patient age, nodule size, the radiologist performing the procedure, and time over the study period. The implementation of a biopsy center was associated with significantly lower rates of nondiagnostic or unsatisfactory thyroid FNA, suggesting target rates of 10% or lower are achievable with quality improvement measures.

The testing facility measurement methods and results of prototype distributed ion pump (DIP) designs for the PEP-II B-Factory High Energy Ring are presented. Two basic designs with 5- or 7-anode plates were tested at LLNL with penning cell sizes of 15, 18, and 21 mm. Direct comparison of 5- and 7-plate anodes with 18 mm holes shows increased pumping speed with the 7-plate design. The 5-plate, 18 mm and 7-plate, 15 mm designs both gave an average pumping speed of 135 1/s/m at 1 {times} 10{sup {minus}8} Torr nitrogen base pressure in a varying 0.18 T peak B-field. Comparison of the three hole sizes indicates that cells smaller than the 15 mm tested can be efficiently used to obtain higher pumping speeds for the same anode plate sizes used.

1956-01-01

An investigation has been completed in the Langley 20-foot free-spinning tunnel on a l/24-scale model of the Grumman F11F-1 airplane to determine its spin and recovery characteristics. An interim report, Research Memorandum SL55G20, was published earlier and the present report concludes the presentation of results of the investigation. Primarily, the present report presents results obtained with engine gyroscopic moments simulated on the model. Also, the current results were obtained with a revised larger vertical tail recently incorporated on the airplane. It was difficult to obtain developed spins on the model when the spin direction was in the same sense as that of the engine rotation (right spin on the airplane). The developed spins obtained were very oscillatory and the recoveries were unsatisfactory. These results were similar to those previously reported for which engine rotation was not simulated. When the spin direction was in the opposite sense (left spin on the airplane), however, developed spins were readily obtainable. Recoveries from these spins also were unsatisfactory. Satisfactory recoveries were obtained on the model, however, when rudder reversal was accompanied by extension of small canards near the nose of the airplane or by deflection of the horizontal tail differentially with the spin.

Cowpea seeds ( Vigna sinensis L.) were exposed to 40 and 80 Gy gamma radiation, in order to study the effect of long period under cooling storage by using RAPD and ISSR PCR facilities. The obtained results indicated that RAPD protocol gave 65% monomorphic and 56% polymorphic fragments between the samples as compared to storage and non-storage controls. While , ISSR protocol gave 83% monomorphic and 85% polymorphic fragments. It should be mentioned that other percentage s 86% and 91% were found among samples in case of using another primers. The results could be summarized as follow: 1-Primer OP - B01 gave 7 monomorphic and 13 polymorphic fragments (65%). 2 - The Primer OP - B02 and Primer OP - B05 gave 4 monomorphic fragments with 14 polymorphic fragments (79%). 3 - The Primer HA-98 gave 4 monomorphic fragments with 19 detected polymorphic 83%. 4 - The Primer HA - 99 and HB-12 gave 3 monomorphic fragments and 17 polymorphic 85 and 86%, respectively. 5 - The Primer HB - 13 gave 2 monomorphic fragments with 21 detected polymorphic fragments 91%. 6 - The primer HA-98 gave 83% while the primer HA - 99 gave 85%. The previous results showed some polymorphism differences among the samples, while the primer HB-12 gave 86% and the primer HB-13 91% exhibited high levels of polymorphism. The DNA of stored cowpea seeds which were exposed to 80 Gy in the presence of zinc showed the highest differentiation , while radiation dose 40 Gy treated with zinc or boron, 80 Gy with boron and 40 or 80 Gy treatment alone compared to the two controls (storage and non storage)

1995-12-31

This symposium brought together a unique mix of scientists, engineers and policy makers to discuss the latest applications of biotechnology to in situ bioremediation and ex situ biodegradation of pollutants and industrial wastes. Several new topics were prominent in the discussions. Chief among these were issues related to environmentally acceptable endpoints, command and control versus incentive driven regulations, bioavailability of pollutants to microbial action, delivery of biodegrading organisms to pollutant plumes, value added production, and genetic probes for monitoring the status of soil consortia. These new issues gave a new perspective to the more traditional topics of the molecular genetics of microorganisms, marine bioremediation, bioprocessing of industrial and agricultural wastes, and engineered bioremediation systems which were featured.

The National Comprehensive Cancer Network clinical practice guidelines in oncology-gastric cancer guidelines have been widely used to provide appropriate recommendations for the treatment of patients with gastric cancer. The aim of this study was to examine the adherence of surgical oncologists, medical oncologists, and radiation oncologists' to the recommended guidelines. A questionnaire asking the treatment options for gastric cancer cases was sent to 394 Chinese oncology specialists, including surgical oncologists, medical oncologists, and radiation oncologists working in hospitals joined in The Western Cooperative Gastrointestinal Oncology Group of China. The questionnaire involved a series of clinical scenarios regarding the interpretation of surgery, neoadjuvant, adjuvant, and advanced treatment planning of gastric cancer. Analysis of 358 respondents (91%) showed variations between each specialization and from the recommended guidelines in the management approaches to specific clinical scenarios. The majority of specialists admitted that less than 50% of patients received multidisciplinary evaluation before treatment. The participants gave different responses to questions involving adjuvant, neoadjuvant, and advanced settings, compared to the recommended guidelines. These results highlight the heterogeneity of the treatment of gastric cancer. Surgical oncologists, medical oncologists, and radiation oncologists are not adhering to the recommended guidelines

Full Text Available The Croatian-Hungarian border section of the Dráva River has been undisturbed for almost a century, and it is characterised by unique fluvial morphology (braided pattern and islands supporting rich habitats and wildlife. However, during the last decades human impact became more and moreintensive. Between 1975 and 1989 three water reservoirs were built on the Croatian section of the river, just 16 km from the beginning of the border-section, altering the hydrology and the sediment characteristics of the river. On a local scale cut-offs, revetments and groynes were built. The aim of the study was to evaluate the effect of these human interventions. As the result of the alteration of the hydrology the channel pattern of the Dráva has been changing from braided to meandering, though on the upstream meandering part the territory and number of islands increased due to the drop of water stages. A cut-off and a groyne influenced only the morphology of a short section. As the result of the cut-off braided pattern became more pronounced, and the groyne caused intensive channel aggradation and gave way to lateral island development.

Herschel CHESS discovery of the fossil cloud that gave birth to the Trapezium and Orion KL

Context. The Orion A molecular complex is a nearby (420 pc), very well studied stellar nursery that is believed to contain examples of triggered star formation. Aims: As part of the Herschel guaranteed time key programme CHESS, we present the discovery of a diffuse gas component in the foreground of the intermediate-mass protostar OMC-2 FIR 4, located in the Orion A region. Methods: Making use of the full HIFI spectrum of OMC-2 FIR 4 obtained in CHESS, we detected several ground-state lines from OH+, H2O+, HF, and CH+, all of them seen in absorption against the dust continuum emission of the protostar's envelope. We derived column densities for each species, as well as an upper limit to the column density of the undetected H3O+. In order to model and characterise the foreground cloud, we used the Meudon PDR code to run a homogeneous grid of models that spans a reasonable range of densities, visual extinctions, cosmic ray ionisation rates and far-ultraviolet (FUV) radiation fields, and studied the implications of adopting the Orion Nebula extinction properties instead of the standard interstellar medium ones. Results: The detected absorption lines peak at a velocity of 9 km s-1, which is blue-shifted by 2 km s-1 with respect to the systemic velocity of OMC-2 FIR 4 (VLSR = 11.4 km s-1). The results of our modelling indicate that the foreground cloud is composed of predominantly neutral diffuse gas (nH = 100 cm-3) and is heavily irradiated by an external source of FUV that most likely arises from the nearby Trapezium OB association. The cloud is 6 pc thick and bears many similarities with the so-called C+ interface between Orion-KL and the Trapezium cluster, 2 pc south of OMC-2 FIR 4. Conclusions: We conclude that the foreground cloud we detected is an extension of the C+ interface seen in the direction of Orion KL, and interpret it to be the remains of the parental cloud of OMC-1, which extends from OMC-1 up to OMC-2.

Local injections of the sclerosing substance polidocanol (Ethoxysclerol) have shown good clinical results in patients with chronic midportion Achilles tendinopathy. After training by the inventors of the technique, sclerosing Ethoxysclerol injections were applied on a group of patients in our center. Sclerosing Ethoxysclerol injections will yield good results in the majority of patients. Case series; Level of evidence, 4. In 113 patients (140 tendons) with Achilles tendinopathy, we identified 62 patients (70 tendons) showing neovascularization on color Doppler ultrasound. Fifty-three Achilles tendons (48 patients) were treated with sclerosing Ethoxysclerol injections, with intervals of 6 weeks and a maximum of 5 sessions. Treatment was completed when neovascularization or pain had disappeared, or when there was no positive treatment effect after 3 to 4 sessions. Forty-eight patients (20 women and 28 men) with a median age of 45 years, (range, 33-68 years) were treated. Median symptom duration was 23 months (range, 3-300 months). Fifty-three tendons were treated with a median of 3 sessions of Ethoxysclerol injections. Six weeks after the last injection, 35% of patients had no complaints, 9% had minimal symptoms, 42% were the same, and 14% had more complaints. Women were 3.8 times (95% confidence interval: 1.1-13.8) more likely to have unsatisfactory outcome than men. Pain correlated positively with neovessels on ultrasound (P < .01). At 2.7 to 5.1 year follow-up, 53% had received additional (surgical/conservative) treatment; 3 of these patients (7.5%) still had complaints of Achilles tendinopathy. In 6 patients, complaints that were still present 6 weeks after treatment had resolved spontaneously by final follow-up. Our study did not confirm the high beneficial value of sclerosing neovascularization in patients with midportion Achilles tendinopathy. Despite the retrospective design of our study, we consider it important to stress that injection of Ethoxysclerol may

The knowledge of dietary rules among patients with diabetes

2017-05-01

Full Text Available Introduction: The incidence of diabetes increases in Poland and all over the world. Diet is an integral element of diabetes therapy. The knowledge of dietary rules and compliance with them facilitates body mass reduction and improves metabolic parameters of the body thus preventing diabetes’ complications development. Aim: The aim of the study was to evaluate the knowledge of dietary rules among diabetic patients. Material and methods: The study included 50 patients with recognized diabetes  who were hospitalized in SPSK-4 hospital in Lublin from January to May, 2016. In the study the diagnostic survey was applied. Results: The knowledge of basic dietary rules in diabetes among the majority of surveyed diabetic patients (64% was unsatisfactory. The most significant deficit included lack of acquaintance with glycemic index and carbohydrate exchanges thus making it impossible to make use of them in preparing everyday meals. The knowledge of the surveyed patients depended on their educational status, place of residence and age. Unsatisfactory knowledge was found among 82% of patients  with primary education vs. 40% with higher education, in 80% with countryside residence vs. 53% residing in town and in 80% of patients aged 31-40  and 41-55 years vs. 50% aged 18-30. Conclusion: Dietary education is a necessary element of diabetes therapy. Educating patients about diabetic diet should be repeated regularly as even patients with long-standing diabetes history have unsatisfactory knowledge about the dietary rules. Preferably, educating should be individual and adjusted to patient’s age and education.

Determinants of outcome for patients undergoing lumbar discectomy: a pilot study.

LENUS (Irish Health Repository)

Hickey, Oonagh T

2012-02-03

BACKGROUND AND OBJECTIVE: One-third of patients who undergo lumbar discectomy continue to suffer from persistent pain postoperatively. Greater preoperative warmth thresholds and greater preoperative cerebrospinal fluid concentrations of stable serum nitric oxide metabolites are associated with a worse outcome. The principal objective of this study was to examine the relationship between patient outcome (defined using the Modified Stauffer-Coventry evaluating criteria) and preoperative pain perception threshold to an electrical stimulus. METHODS: A prospective observational pilot study of patients (n = 39) was performed. Quantitative sensory testing, visual analogue scales for anxiety and pain, the Hospital Anxiety and Depression (HADS) Scale and the McGill Pain Questionnaire were completed, and serum nitric oxide metabolites were measured perioperatively. Excised disc tissue was examined histologically, and immunohistochemistry for phospholipase A2 was performed. RESULTS: Ten patients (26%) had an unsatisfactory outcome. Those with a satisfactory outcome had greater preoperative pain perception thresholds over the affected dermatome, which decreased by 2 months postoperatively. These patients also demonstrated a decrease in nitric oxide metabolites from preoperatively to 18 h postoperatively. Greater preoperative HADS scores, and greater pain intensity 4 h and 24 h postoperatively were associated with an unsatisfactory outcome. CONCLUSION: Patients with a satisfactory outcome demonstrate a decrease in pain perception thresholds and plasma concentration of stable nitric oxide metabolites during the perioperative period. Patients with an unsatisfactory outcome following lumbar discectomy experience greater preoperative anxiety and greater pain during the early postoperative period. These findings justify a larger prospective observational study.

Microbial counts of food contact surfaces at schools depending on a feeding scheme

Full Text Available The prominence of disease transmission between individuals in confined environments is a concern, particularly in the educational environment. With respect to school feeding schemes, food contact surfaces have been shown to be potential vehicles of foodborne pathogens. The aim of this study was to assess the cleanliness of the surfaces that come into contact with food that is provided to children through the National School Nutrition Programme in central South Africa. In each school under study, microbiological samples were collected from the preparation surface and the dominant hand and apron of the food handler. The samples were analysed for total viable counts, coliforms, Escherichia coli, Staphylococcus aureus and yeasts and moulds. The criteria specified in the British Columbia Guide for Environmental Health Officers were used to evaluate the results. Total viable counts were high for all surfaces, with the majority of colonies being too numerous to count (over 100 colonies per plate. Counts of organisms were relatively low, with 20% of the surfaces producing unsatisfactory enumeration of S. aureus and E. coli and 30% unsatisfactory for coliforms. Yeast and mould produced 50% and 60% unsatisfactory counts from preparation surfaces and aprons, respectively. Statistically significant differences could not be established amongst microbial counts of the surfaces, which suggests cross-contamination may have occurred. Contamination may be attributed to foodstuffs and animals in the vicinity of the preparation area rather than to the food handlers, because hands had the lowest counts of enumerated organisms amongst the analysed surfaces.

Mercury's capture into the 3/2 spin-orbit resonance as a result of its chaotic dynamics.

Science.gov (United States)

Correia, Alexandre C M; Laskar, Jacques

2004-06-24

Mercury is locked into a 3/2 spin-orbit resonance where it rotates three times on its axis for every two orbits around the sun. The stability of this equilibrium state is well established, but our understanding of how this state initially arose remains unsatisfactory. Unless one uses an unrealistic tidal model with constant torques (which cannot account for the observed damping of the libration of the planet) the computed probability of capture into 3/2 resonance is very low (about 7 per cent). This led to the proposal that core-mantle friction may have increased the capture probability, but such a process requires very specific values of the core viscosity. Here we show that the chaotic evolution of Mercury's orbit can drive its eccentricity beyond 0.325 during the planet's history, which very efficiently leads to its capture into the 3/2 resonance. In our numerical integrations of 1,000 orbits of Mercury over 4 Gyr, capture into the 3/2 spin-orbit resonant state was the most probable final outcome of the planet's evolution, occurring 55.4 per cent of the time.

The 30 Doradus nebula in the Large Magellanic Cloud (LMC) contains the massive starburst cluster NGC 2070 with a massive and probably younger stellar sub clump at its centre: R136. It is not clear how such a massive inner cluster could form several million years after the older stars in NGC 2070, given that stellar feedback is usually thought to expel gas and inhibit further star formation. Using the recently developed 1D feedback scheme WARPFIELD to scan a large range of cloud and cluster properties, we show that an age offset of several million years between the stellar populations is in fact to be expected given the interplay between feedback and gravity in a giant molecular cloud with a density ≳500 cm-3 due to re-accretion of gas on to the older stellar population. Neither capture of field stars nor gas retention inside the cluster have to be invoked in order to explain the observed age offset in NGC 2070 as well as the structure of the interstellar medium around it.

Two experiments, DCH-3 and DCH-4, were performed at the Surtsey test facility to investigate phenomena associated with a high-pressure melt ejection (HPME) reactor accident sequence resulting in direct containment heating (DCH). These experiments were performed using the same experimental apparatus with identical initial conditions, except that the Surtsey test vessel contained air in DCH-3 and argon in DCH-4. Inerting the vessel with argon eliminated chemical reactions between metallic debris and oxygen. Thus, a comparison of the pressure response in DCH-3 and DCH-4 gave an indication of the DCH contribution due to metal/oxygen reactions. 44 refs., 110 figs., 43 tabs

Effect of Changing Governance System: Result of Western Style Management Adoption to Japanese Culture of Ambiguity

Directory of Open Access Journals (Sweden)

Kohichiro Hotta

2009-02-01

Full Text Available This paper considers the difficulty of management style change through observation of the management style of Company-A, one of the biggest Japanese IT companies. Japanese economy grew after World War II until the early 1990's. During that era, Ba or SECI process worked in Japanese organizations very well. Further, there was an ambiguous culture in the background of such characteristics. Some kinds of ambiguity or adhocracy made positive effects for Japanese organizational activity, or ambiguity played an important role for Ba activity. There were nested Ba's in each organization with ambiguity. Ambiguous descriptions of roles for each organizational unit activated nested Ba's and generated hot groups. After the economic crisis, Company-A changed its governance and gave clear targets for each organizational unit and for each employee. This change gave new difficulty and diminishes its competence. The change denied the ambiguity in the organization but it was the basis of the competence. Adopting a new system of governance is not a simple activity. Systems must be adjusted to the culture of the organization. Company-A should study competitors in different cultures and adjust the methodology for its culture.

Lectures on probability and statistics. Revision

International Nuclear Information System (INIS)

Yost, G.P.

1985-06-01

These notes are based on a set of statistics lectures delivered at Imperial College to the first-year postgraduate students in High Energy Physics. They are designed for the professional experimental scientist. They begin with the fundamentals of probability theory, in which one makes statements about the set of possible outcomes of an experiment, based upon a complete a priori understanding of the experiment. For example, in a roll of a set of (fair) dice, one understands a priori that any given side of each die is equally likely to turn up. From that, we can calculate the probabilty of any specified outcome. They finish with the inverse problem, statistics. Here, one begins with a set of actual data (e.g., the outcomes of a number of rolls of the dice), and attempts to make inferences about the state of nature which gave those data (e.g., the likelihood of seeing any given side of any given die turn up). This is a much more difficult problem, of course, and one's solutions often turn out to be unsatisfactory in one respect or another. Hopefully, the reader will come away from these notes with a feel for some of the problems and uncertainties involved. Although there are standard approaches, most of the time there is no cut and dried ''best'' solution - ''best'' according to every criterion

Enhanced cell surface expression, immunogenicity and genetic stability resulting from a spontaneous truncation of HIV Env expressed by a recombinant MVA

2008-01-01

During propagation of modified vaccinia virus Ankara (MVA) encoding HIV 89.6 Env, a few viral foci stained very prominently. Virus cloned from such foci replicated to higher titers than the parent and displayed enhanced genetic stability on passage. Sequence analysis showed a single nucleotide deletion in the 89.6 env gene of the mutant that caused a frame shift and truncation of 115 amino acids from the cytoplasmic domain. The truncated Env was more highly expressed on the cell surface, induced higher antibody responses than the full-length Env, reacted with HIV neutralizing monoclonal antibodies and mediated CD4/co-receptor-dependent fusion. Intramuscular (IM), intradermal (ID) needleless, and intrarectal (IR) catheter inoculations gave comparable serum IgG responses. However, intraoral (IO) needleless injector route gave the highest IgA in lung washings and IR gave the highest IgA and IgG responses in fecal extracts. Induction of CTL responses in the spleens of individual mice as assayed by intracellular cytokine staining was similar with both the full-length and truncated Env constructs. Induction of acute and memory CTL in the spleens of mice immunized with the truncated Env construct by ID, IO, and IR routes was comparable and higher than by the IM route, but only the IR route induced CTL in the gut-associated lymphoid tissue. Thus, truncation of Env enhanced genetic stability as well as serum and mucosal antibody responses, suggesting the desirability of a similar modification in MVA-based candidate HIV vaccines

The suitability of a roentgenographic method for the determination of per cent composition in a blend the yarn was spun of is analysed. Results were compared to the chemical test. It has been found that as far as a composition of the blend is concerned, the X-ray method might replace the chemical one, however, the appraisal of the blending effect appears unsatisfactory.

Degerblad, M.; Raehn, T.; Bergstrand, G.; Thoren, M.

1986-01-01

Gamma radiation from 60 Co delivered with stereotactic technique was given to the pituitary gland in 35 patients, aged 18-65 years, with Cushing's disease. The doses were 70-100 Gy in each single irradiation. The size of the sella turcica was normal in the majority of the patients. The observation time was 3-9 years in 29 patiens. Out of them, 14 (48%) obtained clinical remission and normal urinary cortisol after one irradiation. Eight achieved remission after two to four irradiations. In total, 22 out of 29 patients (76%) obtained remission. In 12 of them remission was obtained in 1 year and in another 10 within 3 years. No recurrences were observed. Improvement was seen in 2 patients after one and three irradiations. Bilateral adrenalectomy was performed in 5 patients owing to unsatisfactory effect of irradiation. Pituitary insufficiency with gonadotropin, thyrotropin or cortocotropin failure was demonstrated in 12 of 22 patients in remission. This occurred 4 months to 7 years after the first irradiation. Another 6 patients were followed less than 3 years after the first irradiation. Two obtained remission after the first treatment, whereas the other 4 improved. Stereotactic pituitary irradiation is suggested as a non-invasive therapeutic alternative in Cushing's disease for example in patients with considerable surgical risk or as a supplement to pituitary microsurgery.

Preliminary Experimental Results on the Technique of Artificial River Replenishment to Mitigate Sediment Loss Downstream Dams

Science.gov (United States)

Franca, M. J.; Battisacco, E.; Schleiss, A. J.

2014-12-01

The transport of sediments by water throughout the river basins, from the steep slopes of the upstream regions to the sea level, is recognizable important to keep the natural conditions of rivers with a role on their ecology processes. Over the last decades, a reduction on the supply of sand and gravel has been observed downstream dams existing in several alpine rivers. Many studies highlight that the presence of a dam strongly modifies the river behavior in the downstream reach, in terms of morphology and hydrodynamics, with consequences on local ecology. Sediment deficit, bed armoring, river incision and bank instability are the main effects which affect negatively the aquatic habitats and the water quality. One of the proposed techniques to solve the problem of sediment deficit downstream dams, already adopted in few Japanese and German rivers although on an unsatisfactory fashion, is the artificial replenishment of these. Generally, it was verified that the erosion of the replenishments was not satisfactory and the transport rate was not enough to move the sediments to sufficient downstream distances. In order to improve and to provide an engineering answer to make this technique more applicable, a series of laboratory tests are ran as preparatory study to understand the hydrodynamics of the river flow when the replenishment technique is applied. Erodible volumes, with different lengths and submergence conditions, reproducing sediment replenishments volumes, are positioned along a channel bank. Different geometrical combinations of erodible sediment volumes are tested as well on the experimental flume. The first results of the experimental research, concerning erosion time evolution, the influence of discharge and the distance travelled by the eroded sediments, will be presented and discussed.

Use of computer-aided x-ray diagnosis in oncology. [60 refs

The introduction of computer-aided diagnostic reveals new perspectives for diagnostic decisions. The results of the hitherto used mathematical diagnostic models are represented. The Bayes's theorem as the most used model exhibited very different, in part unsatisfactory results. More convenient seem to be multivariate models, like discriminant analysis. Hitherto the computer-aided diagnosis was used in a relative small number of problems concerning differential diagnosis. It is necessary to compare the efficiency of the different mathematical-statistical methods.

Low Level Laser Therapy for the Treatment of Diabetic Foot Ulcers: A Critical Survey

Directory of Open Access Journals (Sweden)

2014-01-01

Full Text Available Diabetic foot ulcers as one of the most common complications of diabetes mellitus are defined as nonhealing or long-lasting chronic skin ulcers in diabetic patients. Multidisciplinary care for the diabetic foot is common, but treatment results are often unsatisfactory. Low level laser therapy (LLLT on wound areas as well as on acupuncture points, as a noninvasive, pain-free method with minor side effects, has been considered as a possible treatment option for the diabetic foot syndrome. A systematic literature review identified 1764 articles on this topic. Finally, we adopted 22 eligible references; 8 of them were cell studies, 6 were animal studies, and 8 were clinical trials. Cell studies and animal studies gave evidence of cellular migration, viability, and proliferation of fibroblast cells, quicker reepithelization and reformed connective tissue, enhancement of microcirculation, and anti-inflammatory effects by inhibition of prostaglandine, interleukin, and cytokine as well as direct antibacterial effects by induction of reactive oxygen species (ROS. The transferral of these data into clinical medicine is under debate. The majority of clinical studies show a potential benefit of LLLT in wound healing of diabetic ulcers. But there are a lot of aspects in these studies limiting final evidence about the actual output of this kind of treatment method. In summary, all studies give enough evidence to continue research on laser therapy for diabetic ulcers, but clinical trials using human models do not provide sufficient evidence to establish the usefulness of LLLT as an effective tool in wound care regimes at present. Further well designed research trials are required to determine the true value of LLLT in routine wound care.

Synthesis and radiolabelling of AG957 a potential tyrphostin PET radiotracer

Full text: Signalling of tyrosine kinases is a critical component of intracellular regulation of growth and function. AG957 is an inhibitor of the c-ABL tyrosine kinase found in chronic myeloid leukemia, and the labelling of AG957 with a PET radiotracer would allow for the in vivo mapping of this receptor-kinase. Synthesis of the normethyl precursor of the tyrosine kinase inhibitor AG957 has been achieved by condensation of p-amino benzoic acid with 2,6 dihydroxy benzaldehyde and subsequent reduction of the imino function with sodium cyanoborohydride. The radiolabeling of this precursor using 11 C-methyliodide in basic conditions gave unsatisfactory yields because of decomposition of the starting material. We have therefore investigated the formation of 11 C-methyl esters using 11 Cmethanol and free carboxylic acids in the presence of either trimethylsilylchloride or boron trifluoride etherate as catalyst. P-amino benzoic acid, benzoic acid and salicylic acid were used as model compounds. Boron trifluoride etherate proved to be superior to trimethylsilylchloride giving good yields of the esters of the respective carboxylic acids when reacted with 11 C-methanol at 150 deg C. However, when this method was applied to desmethyl AG957, none of the desired product was obtained due to decomposition of the precursor at high temperatures. In light of these results we are planning to investigate the irreversible transesterification of enol esters with 11 C-methanol in the presence of a tin catalyst. This reaction is known to proceed smoothly at lower temperatures and should enable us to radiolabel the tyrosine kinase inhibitor 11 C-AG957.

During the First World War soldiers suffered from a wide range of debilitating nervous complaints as a result of the stresses and strains of modern warfare. These complaints--widely known as shell shock--were the subject of much medical-military debate during the war and became emblematic of the war and its sufferings afterwards. One hundred years after the war the diagnosis of PTSD has not resolved the issues initially raised by First World War shell shock. The stigma of mental illness remains strong and it is still difficult to commemorate and remember the mental wounds of war in a culture which tend to glory or glamorise military heroes.

Results of the Schooner excavation experiment

Tewes, Howard A.

1970-01-01

Project Schooner, a nuclear detonation in interlayered hard and soft, partially saturated volcanic rock, was executed as a part of the Plowshare Program for development of nuclear excavation techniques. The primary objectives of this experiment were: (a) to obtain experimental data on crater development and size in a new medium to further verify existing rock mechanics computer codes and calculational techniques; and (b) to determine the fractional release of radioactivity from a nuclear detonation in wet rock. As was noted in the case of the Sedan experiment, appreciable (though relatively small) amounts of radioactivity were released to the environment from this detonation in hard, partially saturated rock. Although the thermo-nuclear explosive used in this experiment gave a yield of approximately 31 kilotons, only the equivalent of the fission products from about 370 tons of fission were distributed in both fallout and cloud. Data which have been reduced to date indicate that this released radioactivity underwent only a moderate amount of chemical fractionation, being much more similar in this respect to Sedan than to Danny Boy.

The paper discuss the use of different distributions of the stochastic component in SUE. A main conclusion is that they generally gave reasonable similar results, except for the LogNormal distribution which use is dissuaded. However, in cases with low link-costs (e.g. in dense urban areas, ramps...... and modelling of intersections and inter-changes), distributions with long tails (Gumbel and Normal) gave biased results com-pared with the Rectangular distribution. The Triangular distribution gave results somewhat between. Besides giving the most reasonable results, the Rectangular dis-tribution is the most...... calculation effective.All distributions gave a unique solution at link level after a sufficient large number of iterations (up to 1,000 at full-scale networks) while the usual aggregated measures of convergence converged quite fast (under 50 iterations). The tests also showed, that the distributions must...

Duggan, Conor; Mason, Lauren; Banerjee, Penny; Milton, John

2007-05-01

Assessing those with personality disorder for treatment in secure settings is known to be unsatisfactory. To examine the utility of a standardised assessment of offenders with personality disorder referred for treatment in secure care in a naturalistic study. A consecutive series of 89 men were assessed with a battery of four recommended instruments measuring personality and risk. Decisions on whether or not to admit were based on a multidisciplinary discussion informed by these assessments. Of the 89 comprehensively assessed referrals, 60 (67%) were offered admission. High scores on the Psychopathy Checklist-Revised (especially on Factor 1) was the only measure that was associated with rejection. Of 44 patients discharged, 29 (66%) failed to complete treatment; none of the pre-admission assessments distinguished ;completers' from ;non-completers'. Although skills were acquired on the unit, follow-up of 24 men in the community showed that this had only a marginal effect on re-offending rate (58%). Current recommended assessment methods appear unsatisfactory in identifying those who either (a) complete treatment or (b) benefit from treatment. Our results throw doubt on their value.

Erroneous HbA1c results in a patient with elevated HbC and HbF.

HbA1c is used in the diagnosis and monitoring of diabetes mellitus (DM). Interference from hemoglobin variants is a well-described phenomenon, particularly with HPLC-based methods. While immunoassays may generate more reliable HbA1c results in the presence of some variants, these methods are susceptible to negative interference from high concentrations of HbF. We report a case where an accurate HbA1c result could not be obtained by any available method due to the presence of a compound hemoglobinopathy. HbA1c was measured by HPLC, immunoassay, and capillary electrophoresis. Hemoglobinopathy investigation consisted of a CBC, hemoglobin fractionation by HPLC and electrophoresis, and molecular analysis. HbA1c analysis by HPLC and capillary electrophoresis gave no result. Analysis by immunoassay yielded HbA1c results of 5.9% (Siemens DCA 2000+) and 5.1% (Roche Integra), which were inconsistent with other markers of glycemic control. Hemoglobinopathy investigation showed HbC with the hereditary persistence of fetal hemoglobin-2 Ghana deletion. Reliable HbA1c results may be unobtainable in the presence of some hemoglobinopathies. HPLC and capillary electrophoresis alerted the laboratory to the presence of an unusual hemoglobinopathy. Immunoassays generated falsely low results without warning, which could lead to missed diagnoses and under treatment of patients with DM. Copyright © 2016 Elsevier B.V. All rights reserved.

This report describes the fiscal 1974 research result on glass system materials of plane collectors for solar cooling/heating. A barrel lens type collector was poorer in efficiency than conventional ones. A one-directional Fresnel lens type one was promising for improvement of solar radiation collection. The prototype In{sub 2}O{sub 3} selective transmission cover glass was prepared by vacuum deposition. Although selective characteristics including a solar transmissivity of 74% and an IR reflectance of 75-80% were obtained, further improvement of more than 10% is necessary. The evaluation results of some collectors are as follows. A vacuum type is poor because of its low efficiency and necessary vacuum sealing. A multi-layer type shows unsatisfactory performance at some temperatures. A glass honeycomb type is most likely because of its uppermost collection efficiency, however, development of production technology of heat-resistant honeycombs and its profitability remain to be solved. A deformed multi-layer type is practical because of its high efficiency, simple structure and low cost. Further improvement of the transmissivity and IR reflectance of cover glass by more than 10% is necessary. (NEDO)

be measured explicitly and are used as fixed parameters in the PARIO evaluation, the error of the clay fraction is determined by error propagation from the sand and silt fraction. Homogenization of the suspension by overhead shaking gave lower reproducibility and smaller silt fractions than vertical stirring. However, it turned out that vertical stirring must be performed with sufficient rigour to obtain a fully homogeneous initial distribution. Analysis of material sieved to < 2000 μm and to < 200 μm gave equal results, i.e., there was no hint towards dragging effects of large particles. Complete removal of the sand fraction, i.e. sieving to < 63 μm lead to less silt, probably due to a loss of fine material by the sieving process. The PSD's obtained with the PARIO corresponded very well with the results of the Pipette method.

Segmentation of buildings in urban areas, especially dense urban areas, by using remotely sensed images is highly desirable. However, segmentation results obtained by using existing algorithms are unsatisfactory because of the unclear boundaries between buildings and the shadows cast by neighboring buildings. In this paper, an algorithm is proposed that successfully segments buildings from aerial photographs, including shadowed buildings in dense urban areas. To handle roofs having rough text...

The molecular pathogenesis of thymomas and thymic carcinomas (TCs) is poorly understood and results of adjuvant therapy are unsatisfactory in case of metastatic disease and tumor recurrence. For these clinical settings, novel therapeutic strategies are urgently needed. Recently, limited sequencing efforts revealed that a broad spectrum of genes that play key roles in various common cancers are rarely affected in thymomas and thymic carcinomas, suggesting that other oncogenic principles might ...

To understand the status of education and problems in paediatric rheumatology practice in Europe, through a survey. A 26-item questionnaire was conducted during the 14th Congress of the Paediatric Rheumatology European Society in Istanbul, 2007. Physicians who were practicing or studying within the field of paediatric rheumatology for at least one year were included in the survey. One hundred and twenty eight physicians, 79 paediatric rheumatologists (including 5 paediatric immunologists and 10 paediatric nephrologists), 34 paediatric rheumatology fellows and 15 adult rheumatologists completed the survey. The physicians were from: Europe 95 (81.9%), South America 12 (10.4%), Middle East 5 (4.3%), Asia 2 (1.7%), Africa 2 (1.7%). The duration of training for paediatric rheumatology ranged between 1-5 years (mean: 3.12+/-1.11). Sixty physicians scored their education as unsatisfactory and among those, 48 physicians were from Europe. Physicians reported good skills in the following items; intraarticular injections (83.3%); soft tissue injections (47.6%); evaluation of radiographs (67.5%); whereas competence in the evaluation of computed tomography/magnetic resonance imaging (30.5%); and musculoskeletal sonography (16.7%) was much lower. A need for improved basic science and rotations among relevant fields were specifically expressed. Being a relatively new speciality in the realm of paediatrics, paediatric rheumatology education at the European level needs to be further discussed, revised and uniformed.

evaluate the efficacy of a nursing intervention based on active observation and resolution of the problems of breastfeeding in the period 24-48h post-partum as regards stopping breastfeeding in mothers who gave birth in Hospital General Universitario, Ciudad Real. A clinical trial was conducted on 100 healthy women who had given birth to a healthy baby in the maternity unit of the Hospital General Universitario Ciudad Real. The results showed that 39.8% of women have problems, and 72% need help to initiate the breastfeeding. Approximately 79.9% continue with breastfeeding after hospital discharge as a result of our intervention. Breastfeeding was stopped by 31.1% of the control group, and by 10.9% in the experimental group (nursing intervention), with significant differences being observed in both groups, with RR 1.29 and 95% CI; 1.04-1.61. Hypogalactia (low milk production) was the most frequent reason for stopping, with no differences in both groups. At 3 months, 16.9% had stopped breastfeeding in the control group, and 9% in the experimental group. At 6 months, 19.3% of the control group did not continue with breastfeeding versus 15.9% in the experimental group. Action, and not only intervention, protocols in the period 48h pospartum when there were problems with breastfeeding were effective for initiation breastfeeding at hospital discharge.

Full Text Available The aim of the study is to analyze the conditions and organization of work of public health workers of state medical organizations in the Far East of Russia according to a medical and sociological survey. Materials and methods. A questionnaire survey was chosen. There are 835 people took part in the poll. To gather social information, three groups of respondents were selected: 1 senior and middle managers, 2 heads of structural units; 3 doctors, various clinical specialties, included in the reserve of management personnel. The collection of statistical data was conducted in 2015- 2017. Statistical analysis of the data was carried out using the methods of calculating relative values, calculating the average values, and ANOVA. Results. According to the obtained results, all groups of respondents believe that present healthcare industry in Russia is developed satisfactorily. Participants in the survey estimate the current state of resources of public health institutions rather low. According to the survey results, health workers give an unsatisfactory assessment of the technical condition of the buildings of medical organizations, of the provision of doctors and middle medical personnel. Among the proposed motivational factors of labor activity, healthcare workers and give a satisfactory assessment of such factors as: the discipline of work, the amount of work, the safety in the workplace, the stability of the workplace and interpersonal relations with colleagues. Opinion of medical workers does not coincide in the assessment of factors: wages, technical support of the workplace, the volume of document circulation, the opportunity for professional development, self-realization and career growth. Senior and middle managers assess these factors as «satisfactory», doctors give an assessment of «unsatisfactory». Heads of structural subdivisions assess the factors of technical support for the workplace, the size of wages and volume of document

Full Text Available The regulations for Protected Designation of Origin require a certification body to verify compliance with the provisions of the product specification. The grated Parmigiano-Reggiano is evaluated with a scorecard containing 21 quantitative descriptors and 4 qualitative evaluations of compliance with the regulations. To better understand the relationship between sensory compliance and quantitative descriptors we have tested 24 samples of grated Parmigiano-Reggiano. Correlations and Partial Least Squares gave us a better understanding of compliance evaluation. The work allowed us to define the most important descriptors in relationship with compliance and showed that it is possible to predict compliance values using descriptor values.

A closed passive system independent of support from the spacecraft or its crew was developed to house five pocket mice for their flight on Apollo XVII. The reaction of potassium superoxide with carbon dioxide and water vapor to produce oxygen provided a habitable atmosphere within the experiment package. The performance of the system and the ability of the mice to survive the key preflight tests gave reasonable assurance that the mice would also withstand the Apollo flight.-

Diagnostic tools appropriate for undertaking interventions to control helminth infections are key to their success. Many diagnostic tests for helminth infection have unsatisfactory performance characteristics and are not well suited for use in the parasite control programmes that are being increasingly implemented. Although the application of modern laboratory research techniques to improve diagnostics for helminth infection has resulted in some technical advances, uptake has not been uniform. Frequently, pilot or proof of concept studies of promising diagnostic technologies have not been followed by much needed product development, and in many settings diagnosis continues to rely on insensitive and unsatisfactory parasitological or serodiagnostic techniques. In contrast, PCR-based xenomonitoring of arthropod vectors, and use of parasite recombinant proteins as reagents for serodiagnostic tests, have resulted in critical advances in the control of specific helminth parasites. The Disease Reference Group on Helminths Infections (DRG4), established in 2009 by the Special Programme for Research and Training in Tropical Diseases (TDR) was given the mandate to review helminthiases research and identify research priorities and gaps. In this review, the diagnostic technologies relevant to control of helminth infections, either available or in development, are reviewed. Critical gaps are identified and opportunities to improve needed technologies are discussed. PMID:22545166

Probabilistic safety analysis for Sizewell B - proof of evidence, established on behalf of the Friends of the Earth, London, within the framework of the Sizewell B power station public inquiry

Hahn, L.

1985-01-01

The conclusions drawn in the study presented by the Oeko-Institut, Freiburg, state that there are indeed advantages in the design of the PWR-type Sizewell-B reactor over other types with regard to certain event sequences, but that on the whole, with regard to overall accident probability, there is no significant progress detectable, or even provable. The main results of the analysis in hand undoubtedly are that the unrealistically favourable data presented in the other two Sizewell studies are brought about not by the design features, but by the assumptions, methods and data applied in the studies, so that certain weak points in the methodological approach common to both studies inevitably lead to similar results. The authors of the study in hand explain some of the weak points of the Westinghouse Study and of the CEGB Study to be as follows: - Lack of error bands of results. - Lack of a quantitative analysis of in-plant fire accidents. - Lack of quantitative analysis of external impacts. - Lack of (CEGB) or unsatisfactory (Westinghouse) evaluation of the measuring, control, and drive systems. - Lack of (CEGB) or unsatisfatory (Westinghouse) evaluation of the human factors. - Completely unsatisfactory evaluation of common-mode failures (i.e. multiple failures due to common cause, undiscovered systems interactions, etc.). - Unacceptable handling and use of available data (using data assessments made by experts, instead of data available from experience).

Yao, Chihyuan; Grelick, Arthur; Lumpkin, Alex H; Sereno, Nicholas S

2005-01-01

A particle accumulator ring (PAR) is used at the Advanced Photon Source (APS) to collect multiple linac bunches and compress them into a 0.3-ns (rms) single bunch for booster injection. A 9.77-MHz fundamental rf system and a 117.3-MHz harmonic rf system are employed for initial beam capture and bunch length compression. Satellite bunches with very low charge form due to rf phase drifts or beam loading change. These satellites, when injected into the booster and then into the storage ring (SR), cause bunch impurity at three buckets from the target bucket. Storage ring and booster bunch cleaning was tried but proved to be difficult due to the top-up mode of operation in the storage ring and tune drift in the booster synchrotron. Recently we implemented a PAR bunch-cleaning system with tune-modulated harmonic rf knockout. Preliminary tests gave a measured SR bunch purity of better than 10

The understandings and meanings eight seventh and eighth grade Latinas gave to science

Science.gov (United States)

Parker, Carolyn Ann

My study examined the experiences of eight seventh and eighth grade girls of Central American descent, in and out of the science classroom. The study was interpretive in design and explored the question, "How did the eight participants understand and make meaning of science?" Guided by a sociocultural perspective and a socially critical stance, I explored issues of educational access, particularly to science, mediated by the relationships and experiences formed by families, peers, science classrooms, schools, and society. Data sources included monthly individual interviews, regular focus group meetings, school observations, and interviews with teachers and family members. Findings include the importance of school science experiences that emphasize hands-on activities and the study of topics relevant to students' everyday lives. School influences that I discuss include English-as-a-Second Language learning, English language ability and its effect on classroom interactions, ability grouping, standardized testing, and teachers' instructional practices. Out-of-school influences I examine include the national science education reform movement, familial expectations, and society and the media's portrayal of science and the scientist. The implications and recommendations of the study are particularly germane to practice. Recommendations for the science classroom include a continued emphasis on hands-on science experiences that incorporate high academic expectations for all students, including second-language learners. Moreover, curriculum should be connected and relevant to students' everyday experiences. Recommendations for outside-the-science classroom include a thoughtful examination of the educational environment created by a school's tracking policy and continued support of meaningful professional development experiences for teachers. Future research and the subsequent development of theory should include a further analysis of the influence of gender, ethnicity, science, and recently immigrated students. A study of the influence of English-language ability on students' educational experiences would be especially informative. Studies like this can assist the science education community to implement gender and culturally-equitable curricula, instructional materials, and assessment strategies that could better meet the needs of students who have historically been underrepresented in the discipline, including, but not limited to, second-language learners and recent immigrants to the United States.

New classification of proximal humeral fractures

Energy Technology Data Exchange (ETDEWEB)

Seemann, W R; Rupp, H G; Siebler, G

1986-08-01

Neer's classification of humeral fractures was proved on 657 patients. This classification enables the radiologist to estimate the risk of avascular necrosis of the head of the humerus. The problematic group is that of four part lesions, which has a 19% incidence of humeral head necrosis. Since in this group minimal osteosynthesis produces better functional results than extensive osteosynthesis, a detailed pre-operative radiological description of the fracture type is necessary in order to spare the patient from extensive surgery which could have unsatisfactory results.

Predictors of an unsatisfactory response to pentavalent antimony in the treatment of American visceral leishmaniasis

Directory of Open Access Journals (Sweden)

Santos Mácia A.

2002-01-01

Full Text Available Although treatment of visceral leishmaniasis with pentavalent antimony is usually successful, some patients require second-line drug therapy, most commonly with amphotericin B. To identify the clinical characteristics that predict an inadequate response to pentavalent antimony, a case-control study was undertaken in Teresina, Piaui, Brazil. Over a two-year period, there were 19 cases of VL in which the staff physicians of a hospital prescribed second-line therapy with amphotericin B after determining that treatment with pentavalent antimony had failed. The control group consisted of 97 patients that were successfully treated with pentavalent antimony. A chart review using univariate and multivariate analysis was performed. The cure rate was 90% with amphotericin B. The odds ratio for the prescription of amphotericin B was 10.2 for children less than one year old, compared with individuals aged over 10 years. Patients who presented coinfection had an OR of 7.1 while those on antibiotics had an OR of 2.8. These data support either undertaking a longer course of therapy with pentavalent antimony for children or using amphotericin B as a first-line agent for children and individuals with coinfections. It also suggests that chemoprophylaxis directed toward bacterial coinfection in small children with VL may be indicated.

Assessments of investors' risk appetite/aversion stance via indicators often yields results which seem unsatisfactory (see e.g. Illing and Aaron (2005)). Understanding how such indicators work therefore seems essential for further improvements. The present paper seeks to contribute to this evolution, focusing on the Global Risk Appetite Index (GRAI) class of indicators going back to Kumar and Persaud (2002). Looking at international stock indices during the subprime crisis in 2007, the plausi...

Dawson, David.

1995-01-01

This project investigates the size of the microbial and fungal biomass of the Of organic horizon of a Picea sitchensis forest soil. The immobilisation of Cs 137 within the microbial and fungal biomass is determined. The translocation of Cs 137 via fungal transport within the organic layers of a Pinus sylvestris forest is also investigated in a laboratory microcosm experiment and under field conditions. The microbial biomass was determined by fumigation-incubation using three soil biocides; chloroform, gamma irradiation and a selective fungicide. All biocides gave similar results for microbial biomass which was calculated from the pooled data to be 1.42 +-0.08 g C m -2 . The selective fungicide did not selectively kill the fungal biomass, it was therefore estimated to be 1.13 +- 0.06 g C m -2 . The fungal biomass was determined independently by the agar-film technique and found to be 10.63 +- 0.8 g C m -2 . The large difference in results is due to the methods used to identify the metabolically active fungal biomass. Chloroform and irradiation treatments yielded similar results for the quantity of Cs 137 immobilised within the fungal biomass. The selective fungicide did not selectively lyse the fungal biomass. The quantity of Cs 137 immobilised within the fungal biomass was estimated to be 8% of the Cs 137 deposition to the Of layer or 25 Bq g -1 C m -2 . The importation of Cs 137 into litterbags in the forest was observed as a cumulative effect over the period of study. The agar-film technique proved unsatisfactory in determining the relationship between Cs 137 importation and fungal growth. However, a significant (P 137 content of the O1 litterbags. A poor relationship was observed for Of litterbags. A large increase in Cs 137 activity on O1 and Of litter in the lab based study was observed although confounded by inadvertent contamination.

Two different types of accelerators have been used for production of ( 18 F)fluoride, and the isotope produced has been used for radiolabelling of 2-fluoro-2-deoxy-D-glucose (2- 18 FDG). A rotating PET scanner, based on two scintillation camera heads, has been developed and used for human 2- 18 FDG studies. The suitability of an energy window in the Compton region for imaging 511 keV photons in scintillation camera systems has been evaluated. A new simplified method for normalizing clinical 2- 18 FDG results has been developed and validated, using erythrocytes as a reference tissue, requiring only one blood sample in the middle of the PET scan to calculate the integrated 2- 18 FDG input function with an accuracy better than 8 percent. An investigation using 2- 18 FDG PET to monitor the effect of therapy in advanced head and neck cancer patients has been performed. We found that low initial metabolic rate of glucose (MRG) predicted a complete local response. The second PET examination gave no further information for this group. In the group of primary tumours and lymph node metastases representing a combination of high initial MRG and small decrease in MRG at he second PET examination, the outcome was unfavourable. An accurate normalization of 2- 18 FDG uptake was essential to evaluate the results of this study. 239 refs, 10 tabs

There has been a resurgence of syphilis diagnoses in Australia. We investigated whether our Treponema pallidum PCR test provides any additional diagnostic information over syphilis serology (chemiluminescence immunoassay [CMIA], Treponema pallidum particle agglutination [TPPA] assay, and the rapid plasma reagin [RPR] flocculation test). A retrospective audit of all T. pallidum PCR requests that came through our laboratory from January 2010 to June 2017 was conducted; data collected included age, gender, site of swab, and results from T. pallidum PCR, syphilis serology, and herpes simplex virus 1 (HSV-1) and HSV-2 PCRs. A total of 441 T. pallidum PCR tests were performed; on average, 3 T. pallidum PCRs per month were requested in 2011, and this rate increased to 17.2 requests per month in 2017. A total of 323 patients had both T. pallidum PCR and syphilis serology performed, with 67% of swabs taken from the genitals. T. pallidum PCR gave positive results for 61/323 (19%) patients; of these 61 patients, 59 (97%) also had positive syphilis serology results ( T. pallidum PCR sensitivity, 68%; specificity, 99%; positive predictive value, 97%; negative predictive value, 89%). Syphilis serology was positive for 91/323 patients (28%); of these 91 patients, 61 (66%) were also T. pallidum PCR positive (syphilis serology sensitivity, 97%; specificity, 88%; positive predictive value, 60%; negative predictive value, 99%). The Cohen's kappa value was 0.74, indicating substantial agreement between the two tests. Our results show that most patients with positive T. pallidum PCR results also had positive syphilis serology. Therefore, T. pallidum PCR adds little clinical value over serology for the diagnosis of syphilis in certain clinical settings. Copyright © 2018 American Society for Microbiology.

1989-01-01

The first clinical results of a new 99m Tc-red blood cell labeling procedure avoiding cell centrifugation are presented. One ml heparinized blood samples were incubated with small amounts of a stannous kit. By titration studies, ideal quantities of sodium hypochlorite for oxidation of extracellular tin and of EDTA as stabilizer of the label were found. The Cl - concentration and pH of the labeled blood were acceptable, and EDTA increased labeling yield and stability determined in vitro by a few percent. The new procedure gave a slightly higher labeling yield than a current technique using centrifugation of cells. Labeling efficiency expressed as cell bound/total activity was 96.6%±1.3% in healthy subjects and 95.5%±2.2% in cardiac patients and remained high for 2 h after reinjection. The biological halflife of labeled cells following the new procedure was 11-12 h rendering it suitable for serial determinations of radionuclide cardiography. (orig.)

Characteristic findings of cervical Papanicolaou tests from transgender patients on androgen therapy: Challenges in detecting dysplasia.

The characteristic features of Papanicolaou (Pap) tests collected from female-to-male (FTM) transgender patients on androgen therapy have not been well defined in the literature. FTM transgender patients require cervical cancer screening with the same recommended frequency as cis-gender females. Dysplasia remains challenging to differentiate from atrophy. Without pertinent history, the atrophic findings in younger transgender patients can be misinterpreted as high-grade dysplasia. A review of all cervical Pap tests of transgender patients receiving androgen therapy (2010-2017) was performed. Bethesda diagnosis, cytomorphological features, HPV testing and cervical biopsy results were reviewed. Eleven transgender patients receiving androgen therapy were identified with 23 cervical Pap tests, 11 HPV tests and five cervical biopsies performed. A review of the Pap tests demonstrated: 57% negative for intraepithelial lesion; 13% unsatisfactory; 13% atypical squamous cells of undetermined significance; 13% atypical squamous cells - cannot exclude high-grade squamous intraepithelial lesion; and 4% high-grade squamous intraepithelial lesion. The rates of abnormal tests were higher than our age-matched cis-gender atrophic cohort rates of unsatisfactory (0.5%), atypical squamous cells of undetermined significance (7%), atypical squamous cells-cannot exclude high-grade squamous intraepithelial lesion (0%) and high-grade squamous intraepithelial lesion (0.5%). The cytological findings from liquid-based preparations included dispersed and clustered parabasal-type cells, scattered degenerated cells, smooth evenly dispersed chromatin, and occasional mild nuclear enlargement and irregularity. Dysplastic cells had larger nuclei, hyperchromatic clumped chromatin, and more irregular nuclear contours. The evaluation of dysplasia can be challenging on Pap tests from transgender patients on androgen therapy. The cohort evaluated had higher rates of unsatisfactory and abnormal Pap tests

ObjectivesTo prospectively investigate the pre and intra-procedural risk factors for immediate (IF) and delayed-onset (DOF) fever development after percutaneous transhepatic biliary drainage (PTBD).MethodsInstitutional review board approval and informed patient consent were obtained. Between February 2013 and February 2014, 97 afebrile patients (77 at the Sapienza University of Rome, Italy and 20 at the Sun Yat-sen University of Guangzhou, China) with benign (n = 31) and malignant (n = 66) indications for a first PTBD were prospectively enrolled. Thirty pre- and intra-procedural clinical/radiological characteristics, including the amount of contrast media injected prior to PTBD placement, were collected in relation to the development of IF (within 24 h) or DOF (after 24 h). Fever was defined as ≥37.5 °C. Binary logistic regression analysis was used to assess independent associations with IF and DOF.ResultsFourteen (14.4 %) patients developed IF and 17 (17.5 %) developed DOF. At multivariable analysis, IF was associated with pre-procedural absence of intrahepatic bile duct dilatation (OR 63.359; 95 % CI 2.658–1510.055; P = 0.010) and low INR (OR 4.7 × 10{sup −4}; 95 % CI 0.000–0.376; P = 0.025), while DOF was associated with unsatisfactory biliary drainage at the end of PTBD (OR 4.571; 95 % CI 1.161–17.992; P = 0.030).ConclusionsThe amount of contrast injected is not associated with post-PTBD fever development. Unsatisfactory biliary drainage at the end of PTBD is associated with DOF, suggesting that complete biliary tree decompression should be pursued within the first PTBD. Patients with unsatisfactory drainage and those with the absence of pre-procedural intrahepatic bile duct dilatation, which is associated with IF, require tailored post-PTBD management.

At multivariable analysis, IF was associated with pre-procedural absence of intrahepatic bile duct dilatation (OR 63.359; 95 % CI 2.658–1510.055; P = 0.010) and low INR (OR 4.7 × 10"−"4; 95 % CI 0.000–0.376; P = 0.025), while DOF was associated with unsatisfactory biliary drainage at the end of PTBD (OR 4.571; 95 % CI 1.161–17.992; P = 0.030).ConclusionsThe amount of contrast injected is not associated with post-PTBD fever development. Unsatisfactory biliary drainage at the end of PTBD is associated with DOF, suggesting that complete biliary tree decompression should be pursued within the first PTBD. Patients with unsatisfactory drainage and those with the absence of pre-procedural intrahepatic bile duct dilatation, which is associated with IF, require tailored post-PTBD management.

Full Text Available The article gives the results of determining peculiarities which are characteristic for adaptation in female migrants de-pending on a period of their staying in Moscow region. Adaptation was assessed as per variants of functional stress status and functional abilities of circulatory system. We detected that female migrants during their adaptation to impacts exerted by neuro-emotional factors, social-psychological factors, and physical (muscular loads which varied in their intensity and length, had signs of stress syndrome. This syndrome was apparent through physiological parameters, namely increase in index of functional changes in circulatory system, and changes in heart rate variability as per regulatory systems activity parameter (PARS. If female migrants stayed in Moscow region for less than 3 years than the most specific weight of migrants with unsatisfactory adaptation was detected among Russians and it was equal to 36.04%; adaptation mechanisms were strained among Tadjiks women (62.08 %. If they stayed for longer than 3 years, then unsatisfactory adaptation parameter grew among Tadjiks women by 12.4 % and it indicated that the body's functional reserves were mobilized and it could lead to adaptation failure. When ad-aptation was satisfactory, β-adrenoactivity of erythrocytes membranes was within the physiological changes standards regardless of a period of staying. When adaptation mechanisms were strained and adaptation itself was unsatisfactory, the greatest growth in this parameter was detected among Tadjiks women in any period of staying. Preservation of female labor migrants health and prolongation of their working capacity period requires a system of med-ical and social support. Activities aimed at primary prevention of health disorders should include general physical training, tempering, autogenous training, and elimination of hazardous communal and occupational risk factors. Secondary prevention activities are systematic medical

The objective of this study was to compare cervical high-grade squamous intraepithelial lesions subcategorized as cervical intraepithelial neoplasia-3 (CIN-3)-positive after a negative cytology result but positive for high-risk human papillomavirus (HR-HPV) testing to those with a negative HR-HPV test but positive cytology (atypical squamous cells of undetermined significance [ASCUS]-positive/HPV-negative) and to assess reasons for discrepancies. The authors retrospectively analyzed women who underwent screening with cytology and HPV testing from 2010 through 2013. After a review of surgical specimens and cytology, discrepancies were classified as sampling or interpretation error. Clinical and pathologic findings were compared. In total, 15,173 women (age range, 25-95 years; 7.1% were aged ASCUS-positive/HPV-positive, 11 that tested negative for intraepithelial lesion or malignancy (NILM)/HPV-positive, 10 that tested ASCUS-positive/HPV-negative, 3 that tested NILM/HPV-negative, and 5 tests that were unsatisfactory. There was no significant difference between NILM/HPV-positive and ASCUS-positive/HPV-negative CIN-3 in terms of size, time to occurrence, the presence of a cytopathic effect, screening history, race, or age. Six of 11 NILM/HPV-positive cases were reclassified as ASCUS, indicating an interpreting error of 55% and a sampling error of 45%. No ASCUS-positive/HPV-negative cases were reclassified. Seven cases of CIN-3 with positive cytology were HPV-negative. There are no significant clinical or pathologic differences between NILM/HPV-positive and ASCUS-positive/HPV-negative CIN-3-positive specimens. Cytologic sampling or interpretation remains the main reason for discrepancies. However, HPV-negative CIN-3 with positive cytology exists and may be missed by primary HPV screening.

Full Text Available Abstract Background Management of environmental health issues is an integral part of public health systems. An active integrated environmental health surveillance and response system was developed for the Athens Olympics to monitor and prevent exposure to environmental hazards. The potential for permanent implementation of the program was examined. Methods The environmental health surveillance and response system included standardization, computerization and electronic transmission of data concerning environmental inspections of 17 site categories (restaurants, swimming pools etc of public health interest, drinking and recreational water examinations and suggested corrective actions. The Olympic Planning Unit integrated and centrally managed data from 13 public health agencies, recommended, supervised and coordinated prompt corrective actions. Methods used to test the effectiveness of the program were the assessment of water quality test and inspection results trends over time using linear regression and epidemiological surveillance findings. Results Between January 2003 and September the 30th, 2004, 196 inspectors conducted 8562 inspections, collected 5024 water samples and recommended 17 027 corrective actions. In 10 cruise ships used as floating hotels inspectors conducted 10 full inspections, 2 re-inspections, and 27 follow-up inspections. Unsatisfactory inspection results (r = 0.44, p Conclusion Lessons learned for future events include timely implementation and installation of communication processes, and rapid and coordinated response to unsatisfactory inspection results. Routine national programs need to adopt enhanced environmental health surveillance aimed at public health decision-making, but with a different perspective.

Organic ion exchange resins were evaluated for 238 Pu(IV), 238 Pu(VI), and 233 U(VI) removal from water. The capacity of the resins and equilibrium coefficients (Kd) were compared with each other and to bone char--an inorganic adsorbent consisting of hydroxyapatite (HAP) for which data is available. Bone char gave the best results for the removal of 238 Pu(IV), Amberlite XE279 (one of the new macroporous resins) gave the best results for 238 Pu(VI), and another macroporous resin, Dowex-MSA-1, gave good results for 233 U(VI). Kd values were shown to be a function of pH

During May and June 1999 a microbiological study of ready-to-eat burgers purchased anonymously from burger outlets (combined take-away and burger restaurants, take-away-only fixed premises, mobile vendors, temporary stalls and other burger outlets) was undertaken. The intention was to determine the microbiological quality of ready-to-eat burgers as purchased by customers of take-away premises and to ascertain, where information was available, whether the Chief Medical Officer's advice on cooking burgers was being followed. Examination of 3,128 ready-to-eat burgers found that 2,868 (92%) were of acceptable quality and 260 (8%) were of unsatisfactory quality. Unsatisfactory results were mostly due to high aerobic colony counts (ACCs). Salmonella spp., Campylobacter spp. and Escherichia coli O157 were not detected in any of the samples examined. Acceptable microbiological quality of ready-to-eat burgers was associated with outlets, such as combined take-away and burger restaurants and in particular national franchise outlets, which had management food hygiene training and hazard analysis in place. Poor microbiological quality was associated with undercooking and local outlets as indicated by Local Authority Inspectors' Consumers at Risk scores.

Full Text Available This study had as its objective to investigate the knowledge of pregnant teenagers on Speech Therapy related to maternal-infant health care. A qualitative analysis was made based on a thematic investigation of the subject matter. Ten pregnant teenagers with chronological age between ten and nineteen years old joined in the survey. They found themselves around the fifth and ninth months of gestation age, being attended at the Center of Pregnant TeenagersAttention Care at Fortaleza General Hospital. The collection of data involved the application of a semi-structured interview broaching topics that could identify what the pregnant teenagers knew about Speech Therapy and maternal-infant care. Education interventions, related to Speech Therapy health promotion, were also accomplished. The results pointed out that the pregnant teenagers’ level of knowledge on aspects such as: food transition and utensils, oral habits, language stimulation and hearing loss detection, was still incipient and unsatisfactory. It is concluded that the knowledge of the pregnant teenagers on Speech Therapy related to maternal-infant health care was unsatisfactory, which demonstrates the importance of education interventions related to human communication health care for this studied sample.

The UK Smoke Constituents Testing Study. Summary of Results and Comparison with Other Studies

Directory of Open Access Journals (Sweden)

Gregg E

2014-12-01

Full Text Available At the request of the UK Department of Health, samples of 25 commercial UK cigarette brands were provided to LGC Ltd a for smoke analysis. The brands reflected a high market share (58% in July 2001 and included a wide range of blend and product styles manufactured and imported into the UK.= 0.76, suggesting a minor role of other design features on constituents yield variability. This was confirmed by the application of multiple regression analysis to the data. A subset of five brands, retested at another laboratory, gave between-laboratory differences in mean constituent yields of as much as 2.5-fold. Consideration of these results, other likely sources of analytical variation in this study and a review of other studies, clearly indicates that any tolerance values to be associated with individual smoke constituent measurements will be greater than those for NFDPM, and in some cases, much greater. Consistent with the reported results from other large studies it is concluded that, under ISO smoking conditions, smoke constituent yields are largely predictable, if NFDPM and CO yields are known, for a standard cigarette. Given these observations and the likely limitations of analytical determination, the need for routine measurement of smoke constituent yields, other than NFDPM, nicotine or CO, on standard cigarettes, is questionable.

[Surgical silicone prostheses in the treatment of biliary tract cancers: long prostheses or short prostheses? Results apropos of 500 cases].

Science.gov (United States)

Kron, B

1992-10-01

The interest of surgical prostheses in the palliative treatment of biliary tract cancer is well established, on the basis of their good tolerance, the more than 15 year follow up experience and the number of patients operated upon. After exeresis, they allow re-establishment of continuity, either by use of a prosthesis in Y when the right and let ducts can be dissected, or by using two prostheses, a multiperforated long prosthesis reimplanted in the duodenum and a short prosthesis reimplanted in the common bile duct without attaining the sphincter of Oddi. Of the 1000 cases treated, 500 were the object of a statistical analysis, 46 being operated upon by the author, in 60% of cases for biliary tract cancer, either primary or as an extension from the gallbladder. One-third of the patients had advanced lesions and a short survival of less than 3 months. Two-thirds a median survival of 9 months. In 10%, a radical exeresis was performed with survival of more than one year without recurrence of jaundice. Failure of treatment with persistence of jaundice was due to advanced disease for which surgery is unsatisfactory. Essential complications were premature bile leaks (5%) without serious consequences if sufficient drainage was maintained, since it stopped spontaneously, and angiocholitis (6%), the result of territory exclusion or reflux. Recurrence of jaundice was related to extension of the neoplasm to the secondary bile ducts, and to hepatic metastases. Obstruction of the prosthesis before two months was rare (6%) and was preceded by angiocholitis. In the absence of recurrence of the cancer the prosthesis can be replaced surgically without difficulty.

The authors developed and evaluated a new procedure for imaging gastric ulcer disease with technetium 99m - labeled sucralfate. The new method employs direct in vivo labeling of sucralfate instead of in vitro labeling using human serum albumin, as previously reported in the literature. In 26 studies using humans with sucralfate labeled directly in vivo, 15 gave true-negative results. Of 14 studies using humans with in vitro labeled sucralfate, three gave true-negative results, three gave true-positive results, and the results of eight were either false-negative or could not be interpreted because of high levels of activity remaining in the stomach. They suggest that the direct in vivo labeling method significantly improves the sucralfate gastric ulcer imaging technique.

2007-01-01

Triple pelvic osteotomy was performed for sequel of DDH including AVN between 1981 and 2002 for 329 patients (351 hips, 280 females, 49 males, average age at surgery 16.5 years, range 9-41 years, follow-up 4-25 years). A small modification of Steel's technique consisting of strictly subperiostal resection of segment from both pubic and ischial bone was used. Average gain of lengthening extremity was 1.8 cm. The average CE angle was improved from 7.8 to 35.5 degrees. Clinical results were evaluated according to Merle d'Aubigne and reflected to the preoperative clinical and radiological findings. There were 146 hip joints in 128 patients (76%) with excellent results in the group of congruent hips without arthrosis. In 182 hips in 178 patients with hip joints with some deformity, limited ROM and decentration, 40% were excellent, 32% good, 23% fair and 5% unsatisfactory results were achieved. The group of decentrated hip joints in young adults in incongruency, limited ROM and sometimes severe arthrosis consisted of 23 monolateral surgeries with 39% unsatisfactory, 39% fair and 22% good results, respectively. No major neurovascular complications were seen. Non-unions were recorded in 19 patients (5.4%), including 2 triple and 2 double non-unions. Based on our long-term experience, we can conclude that triple pelvic osteotomy according to Steel in our modification is a safe method and gives regularly excellent or good results for correction of clinical and radiographic appearance of acetabular dysplasia when there is a proper indication.

This review is trying to address the effectiveness and sustainability of results following minimally invasive repair of pectus excavatum (MIRPE). The aim is to present these results for the benefit of clinicians and the patients. Literature search has revealed 179 hits, which were independently assessed and led to 80 publications being formally reviewed. Studies reporting results from less than 10 patients were excluded. Thirty-five studies were found to be reporting results from patients' and/or surgeons' perspective and they were included in this review. Data from the United Kingdom registry for MIRPE were also included. Results from over 2997 patients (age: reported an 'unsatisfactory end result.' However, these percentages are not necessarily referring to the same patients and an unsatisfactory result does not seem to affect the positive effect on self-esteem. The reported changes in social life, lung capacity, cardiovascular capacity, exercise capacity and general health are based on weak data and significant improvements, if any, are probably seen in a limited number of patients. The metallic bars were removed after 1.5-4.5 years and there is an overall 0-4.5% reported recurrence post-bar removal. In conclusion, MIRPE may improve cosmesis and self-esteem of patients with pectus excavatum deformity. Direct or indirect improvement in other physiological parameters may also help the 'well-being' of these patients and their social integration. There is a clear need for standardisation in the way results are reported in the literature and a socioeconomic analysis with regard to gains, benefits and costs related to MIRPE.

Background Reduction of the adaptation and self-esteem can be the consequence of opium addiction and imprisonment. Drug use causes inappropriate behaviors in women, which are quite different from those in men. Social deviations, prostitution, high-risk sexual behaviors, abortion, divorce and imprisonment followed by loss of self-esteem are the consequences of women's addiction. The present study was conducted to assess the relationship between adaptation and self-esteem in addicted female prisoners. Methods In this descriptive analytical study, 130 addicted female prisoners were selected from a prison in the south east of Iran using census sampling. The data were collected by a demographic questionnaire, the Rosenberg's self-esteem scale and the bell adjustment inventory (BAI). Results According to the results, women's adaptation fell into the 'very unsatisfactory' range. The highest mean was related to the emotional dimension, while the lowest mean was in terms of the health dimension. In total, 96.4% of the participating women had low adaptation. The mean total self-esteem fell into the low range; in fact, 84.6% of the women had a low self-esteem. The results showed no significant relationships between adaptation and self-esteem in these women; however, self-esteem was significantly and inversely related to health and emotional adaptation. Conclusion The findings showed that the majority of the women had unsatisfactory adaptation as well as poor self-esteem. No significant relationships were observed between adaptation and self-esteem in the addicted female prisoners.

Percutaneous ethanol injection (PEI) is an alternative therapy for thyroid nodules (TN). However, some concern is raised on its carcinogenic effects. To evaluate the cytological and clinical changes caused by PEI in patients with benign TN. Thirty-nine patients with TN (23.1% hyperfunctioning) were submitted to a median of three PEI sessions. After a median of 17 months, patients were reassessed. A new ultrasound-guided fine needle biopsy (US-FNB) was performed, and the smears were analyzed after May-Grünwald-Giemsa staining. The diagnostic findings and the cellular characteristics were compared before and after treatment. There was an increase in the proportion of nondiagnostic/unsatisfactory results (from 2.5% to 18.9%). No malignant cases were observed. The proportion of moderate/intense macrophage infiltration decreased from 60% to 15%. Before treatment, 23.1% patients had hyperthyroidism, which was completely or partially resolved in 66.7%. By ultrasound, the percentage of homogeneous nodules decreased from 64.0% to 38.4% (p=0.0235), and the mean nodule volume decreased from 13.4 ± 12.2 to 5.3 ± 5.1 cm(3). We demonstrate that PEI increases the proportion of nondiagnostic/unsatisfactory results from US-FNB. Therefore, cytological findings after PEI must be evaluated with caution. Our results also suggest that PEI is an efficacious and safe therapeutic option, with no carcinogenic effects observed on cytological evaluations. Safety and efficacy must be evaluated in larger studies with longer follow-up periods.

In patients with communicating or normal-pressure hydrocephalus, ventricular volume decreases following implantation of differential pressure valves. We implanted hydrostatic (Miethke dual-switch) valves in 60 patients with normal-pressure hydrocephalus (NPH) between September 1997 and December 2001. The patients underwent CT 1 year after operation, and we measured the Evans index. Although 83% of the patients showed no change in ventricular volume as assessed by this index, 72% nevertheless showed good to excellent and 16% satisfactory clinical improvement, while 12% showed no improvement. Moderate or marked reduction in ventricular size was observed in 17%, of whom 40% of these patients showed good to excellent and 20% satisfactory clinical improvement; 40% showed unsatisfactory improvement. The favourable outcome following implantation of a hydrostatic shunt thus did not correlate with decreased ventricular volume 1 year after operation, better outcomes being observed in patients with little or no alteration in ventricular size than in those with a marked decrease. Postoperative change in ventricular volume in NPH thus does not have the same significance as in patients with high-pressure hydrocephalus. (orig.)

In patients with communicating or normal-pressure hydrocephalus, ventricular volume decreases following implantation of differential pressure valves. We implanted hydrostatic (Miethke dual-switch) valves in 60 patients with normal-pressure hydrocephalus (NPH) between September 1997 and December 2001. The patients underwent CT 1 year after operation, and we measured the Evans index. Although 83% of the patients showed no change in ventricular volume as assessed by this index, 72% nevertheless showed good to excellent and 16% satisfactory clinical improvement, while 12% showed no improvement. Moderate or marked reduction in ventricular size was observed in 17%, of whom 40% of these patients showed good to excellent and 20% satisfactory clinical improvement; 40% showed unsatisfactory improvement. The favourable outcome following implantation of a hydrostatic shunt thus did not correlate with decreased ventricular volume 1 year after operation, better outcomes being observed in patients with little or no alteration in ventricular size than in those with a marked decrease. Postoperative change in ventricular volume in NPH thus does not have the same significance as in patients with high-pressure hydrocephalus. (orig.)

Osser, David N; Roudsari, Mohsen Jalali; Manschreck, Theo

2013-01-01

This article is an update of the algorithm for schizophrenia from the Psychopharmacology Algorithm Project at the Harvard South Shore Program. A literature review was conducted focusing on new data since the last published version (1999-2001). The first-line treatment recommendation for new-onset schizophrenia is with amisulpride, aripiprazole, risperidone, or ziprasidone for four to six weeks. In some settings the trial could be shorter, considering that evidence of clear improvement with antipsychotics usually occurs within the first two weeks. If the trial of the first antipsychotic cannot be completed due to intolerance, try another until one of the four is tolerated and given an adequate trial. There should be evidence of bioavailability. If the response to this adequate trial is unsatisfactory, try a second monotherapy. If the response to this second adequate trial is also unsatisfactory, and if at least one of the first two trials was with risperidone, olanzapine, or a first-generation (typical) antipsychotic, then clozapine is recommended for the third trial. If neither trial was with any these three options, a third trial prior to clozapine should occur, using one of those three. If the response to monotherapy with clozapine (with dose adjusted by using plasma levels) is unsatisfactory, consider adding risperidone, lamotrigine, or ECT. Beyond that point, there is little solid evidence to support further psychopharmacological treatment choices, though we do review possible options.

Occurrence of false positive results for the detection of carbapenemases in carbapenemase-negative Escherichia coli and Klebsiella pneumoniae isolates.

Directory of Open Access Journals (Sweden)

Peng Wang

Full Text Available Adequate detection of the production of carbapenemase in Enterobacteriaceae isolates is crucial for infection control measures and the appropriate choice of antimicrobial therapy. In this study, we investigated the frequency of false positive results for the detection of carbapenemases in carbapenemase-negative Escherichia coli and Klebsiella pneumoniae clinical isolates by the modified Hodge test (MHT. Three hundred and one E. coli and K. pneumoniae clinical isolates were investigated. All produced extended spectrum β-lactamases (ESBLs but were susceptible to carbapenems. Antimicrobial susceptibility testing was performed by the disk diffusion and agar dilution methods. The MHT was performed using the standard inoculum of test organisms recommended by the CLSI. Genes that encoded ESBLs and carbapenemases were identified by PCR and DNA sequencing. Among the 301 clinical isolates, none of the isolates conformed to the criteria for carbapenemase screening recommended by the CLSI. The susceptibility rates for imipenem, meropenem, and ertapenem all were 100.0%, 100.0%, and 100.0%, respectively. Of the 301 E. coli and K. pneumoniae isolates, none produced carbapenemase. The MHT gave a positive result for 3.3% (10/301 of the isolates. False positive results can occur when the MHT is used to detect carbapenemase in ESBL-producing isolates and clinical laboratories must be aware of this fact.

Many of the disturbances resulting from dysregulations in the autonomous nervous system of children with cerebral palsy are rarely discussed in the doctor's praxis. Nevertheless, they are causes of trouble and worry for the parents. For this reason we started an inquiry into this matter. Questionnaires were sent to the parents of 452 C.P. patients. 374 were answered with sufficient care. The following factors were evaluated: sleep, bladder and bowel activity, temperature regulation, vomiting, sweating, blood circulation, growth. The C.P. children were compared to their own siblings especially to the next younger ones. The diagnoses were as follows: Spastic tetraplegia 197 patients. Spastic hemiplegia 44 patients, Athetosis 33 patients, Mixed cases of spasticity and athetosis 82 patients, Other 15 patients. The degrees of handicap in terms of motor development were: severe (unability to sit unsupported) 166 cases, moderate (unability to kneel or walk unsupported) 118 cases, mild (ability to kneel and/or walk unsupported) 87 cases. Summarized, the statements of the parents gave the following results: sleep disturbances: 169 cases (46%), constipation: 145 cases (39%), tendency towards temperature dysregulation: 112 cases (30%) , tendency towards increased vomiting: 91 cases (25%), sweating increased or decreased: 110 cases (30%), irregular and frequent voiding of bladder: 92 cases (25%), unstable regulation of blood circulation: 101 cases (27%), cold skin: 264 cases (71%), body-length deficit: 119 cases (32%), low-weight: 177 cases (48%), feet too small for age: 252 cases (68%). Results are related to diagnosis and severeness of handicap. In addition, it is discussed, whether there are relations between several of the investigated factors. The influence of the patients sex is discussed.

Intraocular pressure (IOP) of 617 eyes was measured with both an AO non-contact tonometer (NCT) and a Goldmann applanation tonometer (GAT). - Statistical evaluation and the scattergram gave the following results: Correlation coefficient r = 0.74. Regression line y = 3.01 + 0.8x. Close agreement between mean GAT (17.8 mmHg) and mean NCT (17.3 mmHg). Variations in readings for NCT-GAT in 92% of all cases with a range of +/- 8 mmHg (95% reliability range) - in some cases much higher or lower - for all IOP values between 10 and 30 mmHg. - Ten NCT measurements were carried out on 42 eyes. The mean values lay between 9 and 22 mmHg, with deviations of up to +/- 6 mmHg from the GAT values. The range was 3 to 13 mmHg, averaging 7.1 mmHg. Standard deviations observed from these measurements were 1.03 minimum, 2.29 average and 3.99 maximum. These were not correlated to IOP. - Changes in the place of applanation are discussed as a possible cause of the variability of NCT readings.

Patient complaints as a means to improve quality of hospital care. Results of a qualitative content analysis

Hoffmann, Susanne; Dreher-Hummel, Thomas; Dollinger, Claudia; Frei, Irena Anna

2018-04-01

Background: Many hospitals have defined procedures for a complaint management. A systematic analysis of patient complaints helps to identify similar complaints and patterns so that targeted improvement measures can be derived (Gallagher & Mazor, 2015). Aim: Our three-month, nurse-led practice development project aimed 1) to identify complaints regarding communication issues, 2) to systemise and prioritise complaints regarding communication issues, and 3) to derive clinic-specific recommendations for improvement. Method: We analysed 273 complaints of patients documented by the quality management (secondary data analysis). Using content analysis and applying the coding taxonomy for inpatient complaints by Reader, Gillespie and Roberts (2014), we distinguished communication-related complaints. By further inductive differentiation of these complaints, we identified patterns and prioritised fields of action. Results: We identified 186 communication-related complaints divided into 16 subcategories. For each subcategory, improvement interventions were derived, discussed and prioritised. Conclusions: Thus, patient complaints provided an excellent opportunity for reflection and workplace learning for nurses. The analysis gave impulse to exemplify the subject “person-centered care” for nurses.

Cluster headache (CH) patients often receive unsatisfactory treatment and may explore illicit substances as alternatives. We aimed to explore this use of illicit drugs for CH treatment. We invited CH patients from an Internet-based self-help group to complete a questionnaire regarding their therapeutic use of illicit substances. Of the 54 respondents, 29 were classified as chronic and 39 were drug-resistant cases. Fifty patients had previously tried subcutaneous sumatriptan, 40 had tried O2, and 48 had tried at least one prophylactic treatment. All 54 patients specified that they were dissatisfied with conventional treatments. Thirty-four patients had used cannabinoids, 13 cocaine, 8 heroin, 18 psilocybin, 12 lysergic acid amide (LSA), and 4 lysergic acid diethylamide (LSD). Some patients with intractable CH decided to try illicit drugs concomitantly with cessation of medical care. Most of these patients found suggestions for illicit drug use on the Internet. Many patients seemed to underestimate the judicial consequences of, and had an overestimated confidence in the safety of, such illicit treatments. Physicians are often not informed by patients of their choice to use illicit drugs. This leads to questions regarding the true nature of the physician-patient relationship among dissatisfied CH patients. © International Headache Society 2015.

Results on the role of metastable Ar atoms in a 9-MHz high-power atmospheric ICP by using emission/absorption spectrometry

Gunter, W.; Zeeman, P.B.; Visser, K.

1984-01-01

An investigation into the role of overpopulations of metastable argon levels as agents for causing non-local thermal equilibrium (LTE) in an inductively coupled plasma source (ICP), was carried out. Four argon transitions in the near infrared region were monitored through absorption measurements at two different observation heights in a 9-MHz high-power ICP. The lower states of the four transitions consist of two metastable (11.55 and 11.72 eV) and two radiating (11.62 and 11.83 eV) levels. Comparison of measured metastable level to radiating level absorbance ratios with calculated population ratios gave an indication whether overpopulations of certain levels existed. Results indicate no overpopulation of metastable states with respect to radiating states, arguing against their role as non-LTE mechanism agents. This conclusion is, however, preliminary, since the calculation of absolute population densities from absorbance measurements must still be carried out

The Ulysses fast latitude scans: COSPIN/KET results

Directory of Open Access Journals (Sweden)

B. Heber

2003-06-01

Full Text Available Ulysses, launched in October 1990, began its second out-of-ecliptic orbit in December 1997, and its second fast latitude scan in September 2000. In contrast to the first fast latitude scan in 1994/1995, during the second fast latitude scan solar activity was close to maximum. The solar magnetic field reversed its polarity around July 2000. While the first latitude scan mainly gave a snapshot of the spatial distribution of galactic cosmic rays, the second one is dominated by temporal variations. Solar particle increases are observed at all heliographic latitudes, including events that produce >250 MeV protons and 50 MeV electrons. Using observations from the University of Chicago’s instrument on board IMP8 at Earth, we find that most solar particle events are observed at both high and low latitudes, indicating either acceleration of these particles over a broad latitude range or an efficient latitudinal transport. The latter is supported by "quiet time" variations in the MeV electron background, if interpreted as Jovian electrons. No latitudinal gradient was found for >106 MeV galactic cosmic ray protons, during the solar maximum fast latitude scan. The electron to proton ratio remains constant and has practically the same value as in the previous solar maximum. Both results indicate that drift is of minor importance. It was expected that, with the reversal of the solar magnetic field and in the declining phase of the solar cycle, this ratio should increase. This was, however, not observed, probably because the transition to the new magnetic cycle was not completely terminated within the heliosphere, as indicated by the Ulysses magnetic field and solar wind measurements. We argue that the new A<0-solar magnetic modulation epoch will establish itself once both polar coronal holes have developed.Key words.

Both the proportional and nonproportional multiaxial fatigue tests were conducted on two kinds of notched specimens of titanium alloy TC4. The multiaxial fatigue critical area of notched specimen is considered as the location experiencing the maximum damage. It is unsatisfactory to predict the multiaxial fatigue life with the local stress and strain in the fatigue critical area. The critical distance concepts are employed in the multiaxial life prediction method for notched specimens. The proposed method was checked by the test data of TC4 notched specimens. The prediction results are almost within a factor of three scatter band of the test results.

The Necessity of Considering Folk Ethics in Moral Philosophy

Full Text Available Contemporary ethics and moral philosophy need a kind of revision due to their negligence in human moral capacities, ordinary life, and humans’ expectations of ethics. The assumptions and presuppositions of ethics result in their current unsatisfactory status. In this paper, we first explore and criticize those presuppositions. Then, instead of introducing ideal presuppositions of ethics, we introduce folk ethics and its components in order to show that contemporary ethics and moral philosophy should always begin with folk ethics. The most important advantage of folk ethics is its realistic foundation, which in turn will produce better results.

1972-01-01

Laboratory and commercial scale experiments with a geobioreagent and the Arlanskii deposit petroleum gave a sharp increase in the content of heavier hydrocarbons, nitrogen, and carbon dioxide in the gas and an increase in the yield of gasoline fraction boiling below 122/sup 0/C. The commercial scale experiments were done in a stratum 1200 m deep during waterflood recovery at 200 kg/cm/sup 2/. A substantial increase in ethane and higher hydrocarbons in the gas and increased petroleum yield were observed, especially after each waterflood. The effect of water was explained by higher activity of the bacteria at a lower concentration of rock salts.

Two different types of accelerators have been used for production of ({sup 18}F)fluoride, and the isotope produced has been used for radiolabelling of 2-fluoro-2-deoxy-D-glucose (2-{sup 18}FDG). A rotating PET scanner, based on two scintillation camera heads, has been developed and used for human 2-{sup 18}FDG studies. The suitability of an energy window in the Compton region for imaging 511 keV photons in scintillation camera systems has been evaluated. A new simplified method for normalizing clinical 2-{sup 18}FDG results has been developed and validated, using erythrocytes as a reference tissue, requiring only one blood sample in the middle of the PET scan to calculate the integrated 2-{sup 18}FDG input function with an accuracy better than 8 percent. An investigation using 2-{sup 18}FDG PET to monitor the effect of therapy in advanced head and neck cancer patients has been performed. We found that low initial metabolic rate of glucose (MRG) predicted a complete local response. The second PET examination gave no further information for this group. In the group of primary tumours and lymph node metastases representing a combination of high initial MRG and small decrease in MRG at he second PET examination, the outcome was unfavourable. An accurate normalization of 2-{sup 18}FDG uptake was essential to evaluate the results of this study. 239 refs, 10 tabs.

Hodgkiss, R.J.; Middleton, R.W.

1983-01-01

A well known inhibitor of glutathione biosynthesis, buthione sulphoximine (S-n-butyl homocysteine sulphoximine, BSO) depletes non-protein sulphydryls (NPSH) in Chinese hamster cells in vitro, resulting in a marked increase in the radiosensitization efficiency of misonidazole. V79 379A Chinese hamster cells were maintained in suspension cultures and irradiated in monolayers using 250 kVp X-rays at a dose rate of 3.93 Gy/min. Radiosensitization by misonidazole alone gave results within 0.1 sensitizer enhancement ratio (s.e.r.) of the curve reported by Watts et al. (1980). GSH (2 mmol dm - 3 ) added to the extracellular medium resulted in a marked decrease in the radiosensitization efficiency of misonidazole, eliminating the effect at 0.1 mmol dm - 3 misonidazole (s.e.r. = 1.0 relative to nitrogen control). A marked enhancement of the radiosensitization by misonidazole was observed when the cells had been incubated with BSO (0.1 mmol dm - 3 ). BSO alone at this concentration gave s.e.r. = 1.17; misonidazole alone (0.1 mmol dm - 3 ) gave s.e.r. = 1.18 and misonidazole with BSO (both 0.1. mmol dm - 3 ) gave s.e.r. = 1.9. The BSO treatment gave little effect in aerated cells. The concentration of BSO needed to produce these effects in vitro is ca. 40-fold lower than doses tolerated by mice in repeated administrations.

Is Low Efficacy of Fungicides always a Consequence of Fungicide Resistance Development in Pathogen Populations?

Directory of Open Access Journals (Sweden)

Brankica Tanović

2011-01-01

Full Text Available Efficacy of four fungicides with different modes of action (vinclozolin, pyrimethanil, benomyland fenhexamid in control of B. cinerea in raspberry, was investigated in the paper.The trials were conducted at two localities in commercial raspberry plantations. In the caseof unsatisfactory fungicide efficacy, qualitative and/or quantitative test of the susceptibilityof the isolates to particular fungicide was performed, to determine whether the low efficacyis a consequence of resistance development in the pathogen population. At both localities,pyrimethanil and fenhexamid demonstrated the highest efficacy (73.2-89.6%, whilethe efficacy of vinclozolin was statistically significantly lower (48.7-63.4% at both localities.However, qualitative and quantitative test of susceptibility to vinclozolin showed that all theisolates were susceptible to vinclozolin and that the reason for unsatisfactory efficacy shouldbe primarily sought in inadequate fungicide application

The outlook for oil prices in 1992 - results of a survey

International Nuclear Information System (INIS)

Hawdon, D.

1992-01-01

The eighth in a series of oil price expectation studies took place on 18th March 1992 at the Prospects for Oil Prices conference held at the University of Surrey. Thirty-one participants returned a questionnaire designed to elicit 12 month ahead and 5 year ahead price expectations. Respondents were asked to indicate their view of the likely price of oil in certain broad price ranges. These were selected to cover the wide variation of prices experienced since the early 1970s. The results show the 12 month's ahead expectations all clustered in the range $10 to $25 per barrel and $16-$20 as the median predicted price. In comparison with the 1991 expectations, a much higher proportion of respondents (77.4 as compared to 50% in 1991) gave $16-20 as their expected price range, whilst fewer expected prices to rise (19% compared with 46% in 1991). The stability of the 12 month ahead price expectations is a remarkable feature of a period which has witnessed much tension in the Middle East and in the former Soviet Union. This stability extends to the 5 year ahead forecasts as well. Here the median expectation is for prices to rise to the $21-25 per barrel range in money of the day terms though there is evidence of a growing scepticism about the oil market's ability to sustain higher prices in the long run.

Theoretical isochrones with decreasing gravitational constant

International Nuclear Information System (INIS)

Vandenberg, D.A.

1976-01-01

Van Flandern has postulated a variation of the gravitational constant at the rate approximately -8 x 10 -11 /yr. This variation, consistent with Hoyle-Narlikar and Dirac cosmologies, has been assumed in the computation of a 5 x 10 9 yr theoretical isochrone. Present results show that, even for this age, theory predicts a cluster turn-off luminosity approximately 0.5 to 1.0 mag fainter than the observed turn-offs of globular clusters. Unsatisfactory agreement between theoretical and observed luminosity functions is also indicated. (author)

2009-01-01

This review article focuses on the therapeutic potential of the incretin hormones, glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), in treating type 2 diabetes mellitus (T2DM). T2DM is characterized by insulin resistance, impaired glucose-induced insulin...... secretion and inappropriately regulated glucagon secretion which in combination eventually result in hyperglycemia and in the longer term microvascular and macrovascular diabetic complications. Traditional treatment modalities--even multidrug approaches--for T2DM are often unsatisfactory at getting patients...

2012-06-01

Full Text Available The paper starts by presenting the model of the star-shaped octorotor. LQR control is chosen to stabilize the attitude and altitude of the vehicle. Waypoint navigation is also implemented. Numerical simulations demonstrate the effectiveness of the control strategy under nominal conditions. However, in practice mass related uncertainties can occur. In this case the results are unsatisfactory. Thus the improvement of the applied LQR control strategy is proposed. It is shown that after adding integral action to the altitude controller the issue is solved.

Ninety-eight patients were included in clinical trials. They were divided into 3 groups, depending on the severity of lower lid inversion. Eighteen patients were included in the group with mild lid inversion; 59 patients had moderate lid inversion and in 21 patients the inversion was severe. Additionally, the patients were subdivided into two groups, according to their age - up to and above the age of 69 years. In both age groups, patients with moderate entropion predominated. All patients underwent photocoagulation of the lower lid. Post-operative wound healing took about 14 days. The effect was described as good when the position of the lid returned to normal with the lashes at an angle of about 45° to the free edge of the eyelid. When the position of the eyelid was normal with the lashes at an angle of about 60° or more to the edge of the lid and not rubbing against the globe, the effect was considered satisfactory. When the inversion of the lid was not corrected, the effect was unsatisfactory. Good effects were seen in 61% of patients, 21% of the patients demonstrated satisfactory effects and in 18% the outcome was unsatisfactory. The best results were observed in patients with mild entropion, aged 69 years and younger.

Objective: To assess the quality and patient satisfaction in Endoscopy Unit of Shifa International Hospital. Study Design: Cross-sectional survey. Place and Duration of Study: Division of Gastroenterology, Shifa International Hospital, Islamabad, Pakistan, from July 2011 to January 2012. Methodology: Quality and patient satisfaction after the endoscopic procedure was assessed using a modified GHAA-9 questionnaire. Data was analyzed using SPSS version 16. Results: A total of 1028 patients were included with a mean age of 45 A+- 14.21 years. Out of all the procedures, 670 (65.17%) were gastroscopies, 181 (17.60%) were flexible sigmoidoscopies and 177 (17.21%) were colonoscopies. The maximum unsatisfactory responses were on the waiting time before the procedure (13.13 %), followed by unsatisfactory explanation of the procedure and answers to questions (7.58%). Overall, unsatisfied impression was 4.86%. The problem rate was 6.22%. Conclusion: The quality of procedures and level of satisfaction of patients undergoing a gastroscopy or colonoscopy was generally good. The factors that influence the satisfaction of these patients are related to communication between doctor and patient, doctor's manner and waiting time for the procedure. Feedback information in an endoscopy unit may be useful in improving standards, including the performance of endoscopists. (author)

Understanding the factors associated with patients' health-related quality of life along with their social networks can help identify who may benefit from supportive programmes. This study sought to evaluate the impact of a cancer diagnosis on Jordanian cancer patients' health-related quality of life and its relationship with social support and emotional status. A descriptive design was utilized, and 226 clients were participated. Participants completed European Organization for Research and Treatment of cancer quality of life questionnaire (EORTC-version 3), the Hospice Comfort Questionnaire, and the Hospital Anxiety and Depression scale. The results revealed that participants demonstrated unsatisfactory quality of life and many complained of fatigue. A multiple linear regression analysis revealed that social support, hospitalization readmission and being a nonsmoker were significant predictors for poor global quality of life score. In addition, a high educational level, less rehospitalization and high anxiety and depression scores were significant predictors for comfort level. In conclusion, patients with cancer are at an elevated risk of impaired physical functioning and report unsatisfactory quality of life, particularly if they are anxious, depressed and lack social support. The associated factors with decreased quality of life or low comfort level could be amenable to change with appropriate interventions. © 2018 John Wiley & Sons Ltd.

Computer-assisted sperm analyzers (CASA) have become the standard tool for evaluating sperm motility and kinetic patterns because they provide objective data for thousands of sperm tracks. However, these devices are not ready-to-use and standardization of analytical practices is a fundamental requirement. In this study, we evaluated the effects of some settings, such as frame rate and frames per field, chamber and time of analysis, and samples preparations, including thawing temperature, sperm sample concentration, and media used for dilution, on the kinetic results of bovine frozen-thawed semen using a CASA. In Experiment 1, the frame rate (30-60 frame/s) significantly affected motility parameters, whereas the number of frames per field (30 or 45) did not seem to affect sperm kinetics. In Experiment 2, the thawing protocol affects sperm motility and kinetic parameters. Sperm sample concentration significantly limited the opportunity to perform the analysis and the kinetic results. A concentration of 100 and 50 x 10(6) sperm/mL limited the device's ability to perform the analysis or gave wrong results, whereas 5, 10, 20, and 30 x 10(6) sperm/mL concentrations allowed the analysis to be performed, but with different results (Experiment 3). The medium used for the dilution of the sample, which is fundamental for a correct sperm head detection, affects sperm motility results (Experiment 4). In this study, Makler and Leja chambers were used to perform the semen analysis with CASA devices. The chamber used significantly affected motility results (Experiment 5). The time between chamber loading and analysis affected sperm velocities, regardless of chamber used. Based on results recorded in this study, we propose that the CASA evaluation of motility of bovine frozen-thawed semen using Hamilton-Thorne IVOS 12.3 should be performed using a frame rate of 60 frame/s and 30 frames per field. Semen should be diluted at least at 20 x 10(6) sperm/mL using PBS. Furthermore, it is

2017-11-01

Full Text Available This paper reports an exploration into Indonesian fourth graders’ difficulties in fractions and their relation to the opportunity to learn fractions students got at schools. The concept of ‘opportunity to learn’ is often considered as a framework to investigate possible reasons for students’ difficulties. The data for this study was drawn from TIMSS 2015 that comprised test results and teachers’ responses to TIMSS Teacher Questionnaire. The test and questionnaire data were analysed by using descriptive statistics. In addition to test and questionnaire, this study also included an analysis of Indonesian textbooks in order to get a broader scope of the opportunity to learn. Qualitative approach was used to analyse the textbooks. The analysis of the TIMSS results shows Indonesian students’ low conceptual understanding of fractions. Three possible reasons for students’ low conceptual understanding were revealed. First, the content of Indonesian curriculum that gave low emphasis on basic concepts of fractions and introduced operations of fractions too early. Second, the Indonesian mathematics textbooks only presented one definition of fractions, i.e. fractions as parts of wholes. Third, there is a limited use of models or representations of fractions in the classroom practices.

The study was conducted to determine the yield of baby corn production treated with wastewater from swine farm. The experiment was set up following the Randomized Complete Block Design with 7 treatments 4 replications. The treatments were no fertilizer, chemical fertilizer, compost, liquid microbial fertilizers (LMF.) of OAP, liquid fish fertilizer (LFF.) of NM., wastewater from swine farm with biogas (SFbg.) and wastewater from swine farm without biogas (SF.). Results at harvested stage of test pot experiment revealed that plant height of liquid fish fertilizer (LFF.) except chemical fertilizer (P<0.01) and dry weight of stem showed highly significant (P<0.01), and chemical fertilizer gave the highest yield (574.76 g/pot). At the same ration of 1:200 LFF of NM and 1:50 of LMF, OAP gave the highest yield of baby corn at 383.76 and 299.88 g per pot respectively. Fresh ear weight of baby corn at harvesting gave significant different (P<0.05). LFF, NM. at the ratio of 1:20 gave the highest yield and higher than chemical fertilizer. But LMF, OAP gave the highest yield at the ratio of 1:50. Fresh ear without husk at harvesting gave highly significant difference (P<0.01), which LFF, NM gave the highest yield at the ratio of 1:200. At the same ratio of 1:50 LMF, OAP gave the highest yield of baby corn. These means that liquid microbial fertilizer of OAP gave the better choice for cheaper cost of reduction in the long term after cultivation in may crops. It will promote the growth of micro-organism in soil for enhancement of soil quality.

Unsatisfactory blood pressure (BP) control so often described in treated hypertensive populations is also explained by insufficient physicians' awareness of experts' guidelines. We assessed awareness of current recommendations about hypertension management in a general practice setting, using the World Health Organization/International Society of Hypertension (WHO/ISH) 1999 guidelines as reference. In a regionwide survey, a total of 5133 physicians (three-quarters of all active general practitioners in Lombardy, a region of north-western Italy) were contacted by letter and received a multiple choice 10-item questionnaire. Data on physicians' demographic characteristics, information on hypertension prevalence and their perception of BP control among their patients were also requested in an additional form. The number of answers in agreement with WHO/ISH guidelines was used as an awareness measure. This was considered adequate if correct answers to six out of 10 questions, including an appropriate definition of hypertension, were provided. Of the 1256 returned questionnaires (a 24.5% response rate), 1162 were suitable for analysis. The mean score of correct answers was 5.3 points and only 20.1% of the study population correctly answered at least six of the questions (including that on the definition of hypertension in the elderly). Guidelines awareness was negatively related to increase in physicians' age and duration of clinical practice and by the male gender. Finally, the physicians reported a high rate of achieved BP control, and those who were considered to have achieved highest rates (>75%) of control in their patients had a lower rate of adequate knowledge than those who reported less-successful therapeutic results (18 vs 25%, P<0.01), suggesting that they ignored or disregarded the goal BP recommended by the guidelines. This large regional survey shows that a sufficient degree of guidelines awareness is present in a minority of primary-care physicians in the

Phenotypic identification systems are established methods for laboratory identification of bacteria causing human infections. Here, the utility of phenotypic identification systems was compared against 16S rDNA identification method on clinical isolates obtained during a 5-year study period, with special emphasis on isolates that gave unsatisfactory identification. One hundred and eighty-seven clinical bacteria isolates were tested with commercial phenotypic identification systems and 16S rDNA sequencing. Isolate identities determined using phenotypic identification systems and 16S rDNA sequencing were compared for similarity at genus and species level, with 16S rDNA sequencing as the reference method. Phenotypic identification systems identified ~46% (86/187) of the isolates with identity similar to that identified using 16S rDNA sequencing. Approximately 39% (73/187) and ~15% (28/187) of the isolates showed different genus identity and could not be identified using the phenotypic identification systems, respectively. Both methods succeeded in determining the species identities of 55 isolates; however, only ~69% (38/55) of the isolates matched at species level. 16S rDNA sequencing could not determine the species of ~20% (37/187) of the isolates. The 16S rDNA sequencing is a useful method over the phenotypic identification systems for the identification of rare and difficult to identify bacteria species. The 16S rDNA sequencing method, however, does have limitation for species-level identification of some bacteria highlighting the need for better bacterial pathogen identification tools. © 2016 Wiley Periodicals, Inc.

With the advent of new imaging modalities, radiologists are faced with handling increasing volumes of data for diagnosis and treatment planning. The use of automated and intelligent systems is becoming essential in such a scenario. Machine learning, a branch of artificial intelligence, is increasingly being used in medical image analysis applications such as image segmentation, registration and computer-aided diagnosis and detection. Histopathological analysis is currently the gold standard for classification of brain tumors. The use of machine learning algorithms along with extraction of relevant features from magnetic resonance imaging (MRI) holds promise of replacing conventional invasive methods of tumor classification. The aim of the study is to classify gliomas into benign and malignant types using MRI data. Retrospective data from 28 patients who were diagnosed with glioma were used for the analysis. WHO Grade II (low-grade astrocytoma) was classified as benign while Grade III (anaplastic astrocytoma) and Grade IV (glioblastoma multiforme) were classified as malignant. Features were extracted from MR spectroscopy. The classification was done using four machine learning algorithms: multilayer perceptrons, support vector machine, random forest and locally weighted learning. Three of the four machine learning algorithms gave an area under ROC curve in excess of 0.80. Random forest gave the best performance in terms of AUC (0.911) while sensitivity was best for locally weighted learning (86.1%). The performance of different machine learning algorithms in the classification of gliomas is promising. An even better performance may be expected by integrating features extracted from other MR sequences. © The Author(s) 2015 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

2007-01-01

This study is carried out to evaluate the performance of some instruments in which the sedimentation technique is used for the determination of particle size distribution using Stoke's law. A mathematical formula has been developed to calculate the particle size distribution for different cases and the results were compared to the real ones. The results revealed unsatisfactory agreement between the calculated and the measured values. In addition, illogic results were obtained indicating that the instruments in which the sedimentation technique is used are not the proper ones to provide accurate measurements except for mono particle size cases. More above, the results obtained represent the sedimentation rate but not the particle size distribution.

To determine the efficacy of percutaneous sclerotherapy in the treatment of aneurysmal bone cysts. Seventeen patients (7 girls, 10 boys) with aneurysmal bone cysts were treated by the percutaneous approach with Ethibloc (n=14) and histoacryl glue (n=3) in our institution between January 1994 and June 2000. The cysts were located in the extremities (n=6), pelvis (n=2), spine (n=2), mandible (n=5), rib (n=1) and sphenoid bone (n=1). Percutaneous sclerotherapy was performed with fluoroscopic and/or computed tomographic guidance under general anesthesia. Clinical and imaging follow-up lasted from 24 months to 9 years and 6 months (mean: 57.3 months). The results were quantified as: excellent (residual cyst less than 20% of the initial involvement), satisfactory (residual cyst 30-50%), unsatisfactory (residual cyst more than 50%). The age of the patients ranged from 4 years and 6 months to 15 years and 8 months (mean: 11 years and 2 months). In nine patients, the therapeutic procedure was repeated 2-5 times. Excellent regression was observed in 16 (94%), satisfactory results in 1 (6%). There was no failure (unsatisfactory result or no response to treatment) in this reported series. The complications were minor and included: local inflammatory reaction (n=2), small blister (n=1), and leakage (n=1). Relief of symptoms was achieved in all patients. No recurrence was noted during follow-up. Percutaneous sclerotherapy of aneurysmal bone cysts with Ethibloc is safe and effective. It is an important alternative to surgery, especially when surgery is technically impossible or not recommended in high-risk patients. (orig.)

Spider silk is a tear-resistant and elastic biopolymer that has outstanding mechanical properties. Additionally, exiguous immunogenicity is anticipated for spider silks. Therefore, spider silk represents a potential ideal biomaterial for medical applications. All known spider silk proteins, so-called spidroins, reveal a composite nature of silk-specific units, allowing the recombinant production of individual and combined segments. In this report, a miniaturized spidroin gene, named VSO1 that contains repetitive motifs of MaSp1 has been synthesized and combined to form multimers of distinct lengths, which were heterologously expressed as elastin-like peptide (ELP) fusion proteins in tobacco. The elastic penetration moduli of layered proteins were analyzed for different spidroin-based biopolymers. Moreover, we present the first immunological analysis of synthetic spidroin-based biopolymers. Characterization of the binding behavior of the sera after immunization by competitive ELISA suggested that the humoral immune response is mainly directed against the fusion partner ELP. In addition, cytocompatibility studies with murine embryonic fibroblasts indicated that recombinant spidroin-based biopolymers, in solution or as coated proteins, are well tolerated. The results show that spidroin-based biopolymers can induce humoral immune responses that are dependent on the fusion partner and the overall protein structure. Furthermore, cytocompatibility assays gave no indication of spidroin-derived cytotoxicity, suggesting that recombinant produced biopolymers composed of spider silk-like repetitive elements are suitable for biomedical applications.

The paper presents the first results from the trigger based on the Discrete Cosine Transform (DCT) operating in the new Front-End Boards with Cyclone V FPGA deployed in 8 test surface detectors in the Pierre Auger Engineering Array. The patterns of the ADC traces generated by very inclined showers were obtained from the Auger database and from the CORSIKA simulation package supported next by Offline reconstruction Auger platform which gives a predicted digitized signal profiles. Simulations for many variants of the initial angle of shower, initialization depth in the atmosphere, type of particle and its initial energy gave a boundary of the DCT coefficients used next for the on-line pattern recognition in the FPGA. Preliminary results have proven a right approach. We registered several showers triggered by the DCT for 120 MSps and 160 MSps. (authors)

Besides presenting data in a format useful to plasma modellers, these data collection activities also serve the function of disclosing gaps in the available data base. The IAEA review panel has pointed out that information on processes of electron ejection and reflection is sparse and is generally unsatisfactory for purposes of modelling sheath effects. The US and Japanese Data Centers recently held a joint workshop where it was concluded that data on trapping and reemission was in an unsatisfactory state. In this case the parameters used to record the phenomena are closely related to the model adopted to describe the process. Existing handbooks on materials are generally weak in the areas closely related to metallurgical properties. All three data centers continue to pursue different aspects of the data collection and review process with a close interaction to avoid significant overlap of activities

There is increasing interest in forensic ancestry tests, which are part of a growing number of DNA analyses that can enhance routine profiling by obtaining additional genetic information about unidentified DNA donors. Nearly all ancestry tests use single nucleotide polymorphisms (SNPs), but these currently rely on SNaPshot single base extension chemistry that can fail to detect mixed DNA. Insertion-deletion polymorphism (Indel) tests have been developed using dye-labeled primers that allow direct capillary electrophoresis detection of PCR products (PCR-to-CE). PCR-to-CE maintains the direct relationship between input DNA and signal strength as each marker is detected with a single dye, so mixed DNA is more reliably detected. We report the results of a collaborative inter-laboratory exercise of 19 participants (15 from the EDNAP European DNA Profiling group) that assessed a 34-plex SNP test using SNaPshot and a 46-plex Indel test using PCR-to-CE. Laboratories were asked to type five samples with different ancestries and detect an additional mixed DNA sample. Statistical inference of ancestry was made by participants using the Snipper online Bayes analysis portal plus an optional PCA module that analyzes the genotype data alongside calculation of Bayes likelihood ratios. Exercise results indicated consistent genotyping performance from both tests, reaching a particularly high level of reliability for the Indel test. SNP genotyping gave 93.5% concordance (compared to the organizing laboratory's data) that rose to 97.3% excluding one laboratory with a large number of miscalled genotypes. Indel genotyping gave a higher concordance rate of 99.8% and a reduced no-call rate compared to SNP analysis. All participants detected the mixture from their Indel peak height data and successfully assigned the correct ancestry to the other samples using Snipper, with the exception of one laboratory with SNP miscalls that incorrectly assigned ancestry of two samples and did not obtain

In many areas of ventilation, air-conditioning and refrigeration engineering, chemical and process engineering and energy production waste heat occurs. If a reduction in energy losses or heat recovery is not possible waste heat has to be drawn off through cooling systems. For this the following systems can be used: dry cooling systems, dry cooler with spray system, open-cycle wet cooler, hybrid dry cooler, and closed-cycle wet cooler. Particularly hybrid cooling systems can give acceptable solutions when the results with other systems are only unsatisfactory. (BWI).

2009-01-01

Biliary endoprosthesis, including plastic stents and metallic stents, have been widely used in the management of various benign or malignant bile duct stenosis. Although the short-term effect is most satisfactory, the long-term result is unsatisfactory because of the displacement and restenosis of the stent. Metallic stent is superior to plastic stent in keeping the stent open for long time and the technique has been improved gradually. This paper aims to make a review of the related literatures and to summarize the recent progress in the applied research. (authors)

We discuss an extension of our method image inpainting based on coherence transport. For the latter method the pixels of the inpainting domain have to be serialized into an ordered list. Until now, to induce the serialization we have used the distance to boundary map. But there are inpainting problems where the distance to boundary serialization causes unsatisfactory inpainting results. In the present work we demonstrate cases where we can resolve the difficulties by employing other distance functions which better suit the problem at hand. © 2011 Society for Industrial and Applied Mathematics.

Although reverse-phase liquid chromatography (RP-LC) is a common technique for peptide separation in shotgun proteomics and glycoproteomics, it often provides unsatisfactory results for the analysis of glycopeptides and glycans. This bias against glycopeptides makes it difficult to study glycoproteins. By coupling mass spectrometry (MS) with a combination of RP-LC and normal-phase (NP)-LC as an integrated front-end separation system, we demonstrate that effective identification and characterization of both peptides and glycopeptides mixtures, and their constituent glycan structures, can be achieved from a single sample injection event.

Proximal humeral fractures are common lesions; there is no generally accepted strategy about the treatment for displaced and unstable two- to four-part fractures. We have nowadays many different surgical solutions, ranging from percutaneous pinning to shoulder arthroplasty. Percutaneous plating can be a good solution to treat some of these fractures using a minimally invasive technique and performing stable fixation that can allow early mobilization. Purpose of this paper is to evaluate the results of our first cases of percutaneous plating in proximal humeral fractures in order to assess the theoretical advantages and the incidence of possible complications. From June 2009 to February 2012, we treated 29 proximal humeral fractures with a percutaneous plating (NCB-PH plate) through an anterolateral deltoid split. For each patient, we evaluated the clinical outcome according to Constant score and the radiographic results, paying attention to fracture healing, loss of reduction, hardware complications, and head necrosis. The clinical evaluation gave a mean Constant score value of 79 points. Comparing each value to the unaffected shoulder, we could find these results: 7 excellent, 10 good, 8 fair, and 4 poor. No axillary nerve lesions were clinically detected. The radiographic evaluation showed a complete bone healing in all cases within the first 3 months. No head necrosis was detected, as well as screws loosening. In two cases, the X-ray at 2 months revealed a little loss of reduction in varus. Two patients had an anterior pain; in one of these two cases, the plate was removed. In our series, we had no cases of head necrosis, screws cutout, fracture collapse, hardware mobilization, and we think this could be the real advantage of the percutaneous technique compared to the open one, thanks to the reduced biological damage. We had some poor results, related more to patient's age than to other factors. The safety of the technique for the axillary nerve is

Comparison of results for morphine urinalyses by radioimmunoassay and thin-layer chromatography in a narcotic clinic setting.

Kokoski, R J; Jain, M

1975-03-01

Radioimmunoassay (RIA) and thin-layer chromatography (TLC) were compared for morphine detection in an actual narcotic clinic setting. A choice of urines from all those screened by TLC allowed a critical comparison as to actual use or non-use of narcotic drugs, rather than a sampling at random in which the question of possible false positives or negatives cannot be conclusively answered. Although RIA is more sensitive than TLC, its advantage is apparent only in those cases where urine specimens are difficult to obtain frequently regularly or where the use of morphine is suspected by the positive identification of quinine in urine that was morphine-negative by TLC. In a selected group of negative and positive specimens chosen without conscious bias, the two methods gave consistently similar results, indicating that the modified TLC method provided a few or no false positives or negatives if the negatives were from those cases that were not positive anytime up to 3-4 days before urine collection. We conclude that RIA can be of significant value as a supplement to a TLC screening program, without sacrificing the many advantages that TLC has to offer.

Patients with advanced stage Hodgkin lymphoma still present unsatisfactory outcomes. The Groupe d'étude des Leucémies Aigues et des Maladies du Sang (GOELAMS) group conducted a prospective multicentric trial (NCT00920153) for advanced stage Hodgkin lymphoma to evaluate a positron emission tomography (PET)-adapted strategy. Patients received an intensive regimen (VABEM [vindesine, doxorubicin, carmustine, etoposide, and methylprednisolone]) in front-line and interim 18F FDG-PET evaluation after 2 courses (PET-2). Patients with negative PET-2 findings received 1 additional course. Patients with positive PET-2 findings underwent early salvage therapy followed by high-dose therapy/autologous stem cell transplantation. Fifty-one patients were included. The final complete remission rate was 88%. With a median follow up of 5.3 years, 5-year event-free survival and overall survival rates were 75.3% and 85.3%, respectively, for the whole cohort. Patients who were PET-2-negative had 5-year event-free survival and overall survival rates of, respectively, 77.8% and 88.2% versus 85.1% and 91.7% for patients who were PET-2-positive. A PET-guided strategy with early salvage therapy and high-dose therapy/autologous stem cell transplantation for patients with interim PET-2-positive findings is safe and feasible and provide similar outcome as patients with a negative PET-2.

Poliomyelitis on an epidemic scale gave rise to several challenges, one of which was the rehabilitation from the after-effects on many of the people who suffered from the disease. Paralysis and the ways it transformed the concept of physical rehabilitation (where the objective was only to restore the mobility of the affected muscles) and comprehensive rehabilitation that included social, educational and professional aspects in Argentina in the mid-twentieth century are the themes addressed in this article. It uses the methodology of institutional history that interacts in an ongoing manner with the history of health and disease.

Rb-Sr systematics have been applied on rocks from the Sao Felix do Xingu region, in the southeastern part of the State of Para. An age of 2716 ± 34 Ma with IR of 0.70292 ± 0.00030 (MSWD = 1.54) and an age of 2677 ± 50 Ma with IR of 0.70161 ± 0.00022 (MSWD = 5.21) had been obtained for a granitic body and a tonalitic body respectively, both of them associated to the green stones belts that occur in this area. Gneisses from the Xingu complex gave an age of 2574 ± 57 Ma with an IR of 0.70416 ± 0.00054 (MSWD = 5.06). An age of 1653 ± 14 Ma with IR of 0.70823 ± 0.02361 (MSWD = 1.71) had been obtained for the Velho Guilherme granite that crosscut the granite-green stones terrains. Such geochronological data show the existence of a magmatic event between 2.72 Ga and 2.68 Ga and permit us to conclude on the archaean age of the green stones terrains. (author)

Reutilização de efluente de tingimentos de fibras acrílicas pós-tratamento fotoeletroquímico Reuse of a effluent from the dyeing of acrylic fabrics after photoelectrochemical treatment

Directory of Open Access Journals (Sweden)

Mônica Lucas

2008-01-01

Full Text Available On a laboratory scale effluents were produced from bichromic dyeing of acrylic fabrics with the basic dyes Blue Astrazon FGGL 300% and Yellow Gold Astrazon GL 200%. The residual dyeing baths were subjected to a photoelectrochemical treatment and reused in a second dyeing process. In the reutilization study, dyeings with treated effluent were compared with standard dyeings with distilled water. The results of dyeings using 100% of treated effluent were unsatisfactory, but the substitution of 10 to 30% of the treated effluent by distilled water resulted in reduced and more acceptable values for difference in colour intensity (ΔE between 1.86 and 0.3.

The purpose of this study was to examine the incidence and implications of false-negative exercise electrocardiographic results among 216 consecutive patients with angiographically documented coronary artery disease (50 percent diameter narrowing or greater of one or more vessels). Exercise electrocardiography gave negative (false-negative) results in 23 patients and positive (true-positive) results in 102 patients, and were nondiagnostic in the rest. Exercise thallium-201 imaging was performed in 88 patients. The extent of coronary artery disease was quantitated by a scoring system that takes into consideration the degree and site of narrowing in the major vessels and their branches. The exercise heart rate was higher in patients with false-negative than in patients with true-positive exercise electrocardiographic results (161 +/- 18 versus 133 +/- 24 beats per minute, mean +/- SD; p less than 0.0001). Q-wave infarction was present in two patients (9 percent) with false-negative and 20 patients (20 percent) with true-positive exercise electrocardiographic results; left ventricular asynergy at rest was observed in 13 patients (57 percent) with false-negative and in 74 patients (74 percent) with true-positive results. Patients with false-negative results had less extensive coronary disease than did patients with true-positive results (score 5.8 +/- 3.6 versus 9.2 +/- 5.0; p . 0.0025). Angina during exercise was less frequent in patients with false-negative results (p less than 0.01). Abnormal exercise thallium-201 images were seen in 15 of 20 patients (75 percent) with false-negative results and in 56 of 68 patients (82 percent) with true-positive results

We report the results of a VAMAS (Versailles Project on Advanced Materials and Standards) interlaboratory study on the measurement of composition in organic depth profiling. Layered samples with known binary compositions of Irganox 1010 and either Irganox 1098 or Fmoc-pentafluoro-L-phenylalanine in each layer were manufactured in a single batch and distributed to more than 20 participating laboratories. The samples were analyzed using argon cluster ion sputtering and either X-ray Photoelectron Spectroscopy (XPS) or Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) to generate depth profiles. Participants were asked to estimate the volume fractions in two of the layers and were provided with the compositions of all other layers. Participants using XPS provided volume fractions within 0.03 of the nominal values. Participants using ToF-SIMS either made no attempt, or used various methods that gave results ranging in error from 0.02 to over 0.10 in volume fraction, the latter representing a 50% relative error for a nominal volume fraction of 0.2. Error was predominantly caused by inadequacy in the ability to compensate for primary ion intensity variations and the matrix effect in SIMS. Matrix effects in these materials appear to be more pronounced as the number of atoms in both the primary analytical ion and the secondary ion increase. Using the participants’ data we show that organic SIMS matrix effects can be measured and are remarkably consistent between instruments. We provide recommendations for identifying and compensating for matrix effects. Finally we demonstrate, using a simple normalization method, that virtually all ToF-SIMS participants could have obtained estimates of volume fraction that were at least as accurate and consistent as XPS.

Assessing incentive contracts for reducing residential electricity consumption: new experimental methods for new results

International Nuclear Information System (INIS)

Frachet, Laure

2013-01-01

Facing economic, political and environmental stakes, electricity providers are nowadays developing incentive tools, in order to reduce consumer's demand, particularly during peak demand periods. For residential customers, these tools can be tariffs (dynamic pricing of time-of-use tariffs), or informative devices or services (feedbacks on historical or real-time consumption, given on various media). They might go along with automation systems that can help cutting of some electric devices when needed. In order to evaluate the capacity of these settings among their customers, electricity utilities are developing quite a few studies, which are mainly field experiment often called pilots. During these pilots, demand response tools are implemented on a population sample. These long and expensive studies lid to quantitative and qualitative analysis. We have compiled about 40 of them and extract from this survey some generalizable teachings. We have shown what these results were and highlighted pilot programs' methodological limits. In order to propose a substitute to these heavy experimentations, we assessed the capacity or experimental economics. This relatively new discipline's objective is to evaluation the efficiency of institutions, like markets, but also to study what animate economic agents' behaviour, e.g. preferences, beliefs, cognitive biases, willingness to pay... We were also able to elaborate an experimental protocol dedicated to the evaluation of some demand response contracts' acceptability. The results collected during 14 experimental sessions gave us some innovative clues and insight on these contracts acceptability. But, beyond these results, we have demonstrated that even if experimental economics can't obviously be a substitute for field experiments, it can represent an interesting exploratory methodology. To sum up the experimental economics can take part of residential customers' behaviour understanding, performing

Full Text Available In terms of GDV prevention, a number of non-surgical measures are recommended. However, the only truly reliable method is gastropexy, most often as part of a surgical treatment of GDV. Gastropexy may be performed preventively either during laparotomy indicated for another reason than GDV, or newly laparoscopically, as independent preventive gastropexy. Preventive laparoscopic assisted gastropexy (PLAG was performed in 17 patients at the Department of Surgery and Orthopaedics of the Small Animal Clinic at the University of Veterinary and Pharmaceutical Sciences in Brno. Clinical results and complications of PLAG were evaluated 3-12 months after surgery. The most frequent clinical finding of PLAG was a skinfold at the site of gastropexy immediately after the surgery (n = 8; 47%, or still on day 12 after the surgery (n = 1; 6%. As for PLAG complications, in one case a seroma formation was found at the site of gastropexy (6%; in two patients iatrogenic perforation of the splenic capsule (12% occurred, which in one case gave reason to converting laparoscopy into laparotomy (6%. In none of the patients, death, gastropexy failure, GDV development, dehiscence, infection of or haemorrhage from the surgical wound were noted. Laparoscopic assisted gastropexy appears as a reliable and miniinvasive surgical method of GDV prevention and it may be recommended for high-risk breeds of dogs.

Unhealthy snacking is commonly seen among adolescents. Therefore, use of food labels is promoted for making healthier choices on packaged snacks. This study was conducted to assess the use of food labels in making choices on packaged snack and its associated factors among adolescents. A cross-sectional study was conducted in 2012 among 542 Grade 12 students in Sri Lanka. Eight classes were selected as 'clusters' for the study (two classes each from two schools that were selected randomly from each list of 'Girls only' and 'Boys only' schools in Colombo district). A self-administered questionnaire assessed their socio-demography, snacking behaviour, attitudes and nutrition knowledge related to food labels. Adolescents' use of labels was assessed by three practices (label reading frequency, attention paid to label contents and correct interpretation of six hypothetical labels of snacks). Based on total scores obtained for the three practices, 'satisfactory' (score ≥75(th) percentile mark) and 'unsatisfactory' (score pocket money at least once/week on packaged snacks; predominantly on biscuits (85 %) and cola-drinks (77 %) and 88 % selected snacks on their own. The majority (74.5 %) was frequent ('always' or 'most often') label readers with female predominance (p < 0.05). Over 74 % paid attention frequently to the brand name (75 %), price (85 %) and nutrition panel (81 %). Over 64 % were able to select the better food label when given a choice between two snacks, although some did it for reasons such as attractive label (63 %). The majority (84 %) had good knowledge (obtaining more than the 75(th) percentile mark) on interpreting labels. Although not statistically significant, 'unsatisfactory' label use was higher among males (73 %), purchasing power (70.4 %) and unhealthy snacking behaviour (73 %). In contrast, among the marketing strategies, identifying known brands (73.2 %) and imported products (75.8 %) as 'good' products were significantly

Simple messages help set the record straight about scientific agreement on human-caused climate change: the results of two experiments.

Directory of Open Access Journals (Sweden)

Teresa A Myers

Full Text Available Human-caused climate change is happening; nearly all climate scientists are convinced of this basic fact according to surveys of experts and reviews of the peer-reviewed literature. Yet, among the American public, there is widespread misunderstanding of this scientific consensus. In this paper, we report results from two experiments, conducted with national samples of American adults, that tested messages designed to convey the high level of agreement in the climate science community about human-caused climate change. The first experiment tested hypotheses about providing numeric versus non-numeric assertions concerning the level of scientific agreement. We found that numeric statements resulted in higher estimates of the scientific agreement. The second experiment tested the effect of eliciting respondents' estimates of scientific agreement prior to presenting them with a statement about the level of scientific agreement. Participants who estimated the level of agreement prior to being shown the corrective statement gave higher estimates of the scientific consensus than respondents who were not asked to estimate in advance, indicating that incorporating an "estimation and reveal" technique into public communication about scientific consensus may be effective. The interaction of messages with political ideology was also tested, and demonstrated that messages were approximately equally effective among liberals and conservatives. Implications for theory and practice are discussed.

Densiron® was injected in all patients, with surgical retinectomy being required in 70% of them. Minimum follow-up time was 12 months. The mean length of time before Densiron® withdrawal was 4 months. Three patients (30%) presented with a new RD. The main complication detected was cataract development. No relationship was found between re-detachments and tamponade time, baseline disease or RD evolution time. Densiron® may be a good option in cases of recurrent RD in which previous treatment with scleral buckle, gas and/or 1,000/5,000 silicone oils has proven to be unsatisfactory.

Is colposcopy necessary at twelve months after large loop excision of the transformation zone? A clinical audit.

Science.gov (United States)

Thompson, Valerie; Marin, Raymond

2013-12-01

The purpose of this study was to review outcomes from LLETZ (large loop excision of the transformation zone) procedures carried out for high-grade cervical intraepithelial neoplasia (CIN), in particular findings at colposcopy, cytology and HR-HPV(high-risk human papilloma virus) result to assess whether colposcopy provides any additional information in the management of women at 12 months. We retrospectively analysed 252 patients who had a LLETZ procedure for a HSIL (high-grade squamous intraepithelial lesion) between January 2005 and December 2010. Eighty per cent of women who had a LLETZ procedure for HSIL were reviewed in our colposcopy clinic at 12 months after the procedure. Colposcopy at 12 months after LLETZ was documented as unsatisfactory for 30% of these women. The sensitivity of colposcopy at 12 months after LLETZ was 0.47, and the specificity was 0.95. Colposcopy examination is an insensitive tool for detection of persisting HPV-related change after excision of high-grade CIN. Its usefulness to investigate persistent or recurrent HSIL is further reduced by the high rate of unsatisfactory colposcopy examinations after a LLETZ procedure. Papanicolaou smear and HRHPV tests may be adequate follow-up at 12 months after LLETZ for women at low risk of recurrence of HSIL. © 2013 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

The Meat Standards Australia (MSA) grading scheme has the ability to predict beef eating quality for each 'cut×cooking method combination' from animal and carcass traits such as sex, age, breed, marbling, hot carcass weight and fatness, ageing time, etc. Following MSA testing protocols, a total of 22 different muscles, cooked by four different cooking methods and to three different degrees of doneness, were tasted by over 19 000 consumers from Northern Ireland, Poland, Ireland, France and Australia. Consumers scored the sensory characteristics (tenderness, flavor liking, juiciness and overall liking) and then allocated samples to one of four quality grades: unsatisfactory, good-every-day, better-than-every-day and premium. We observed that 26% of the beef was unsatisfactory. As previously reported, 68% of samples were allocated to the correct quality grades using the MSA grading scheme. Furthermore, only 7% of the beef unsatisfactory to consumers was misclassified as acceptable. Overall, we concluded that an MSA-like grading scheme could be used to predict beef eating quality and hence underpin commercial brands or labels in a number of European countries, and possibly the whole of Europe. In addition, such an eating quality guarantee system may allow the implementation of an MSA genetic index to improve eating quality through genetics as well as through management. Finally, such an eating quality guarantee system is likely to generate economic benefits to be shared along the beef supply chain from farmers to retailors, as consumers are willing to pay more for a better quality product.

To assess the risk of developing high-grade cervical dysplasia among women with low-grade cervical cytology and nonvisible squamocolumnar junction (SCJ) at colposcopic examination. Data of consecutive women with low-grade intraepithelial lesion(≤LSIL) undergoing colposcopic examination, which was unsatisfactory (due to the lack of the visualization of the entire SCJ), were retrospectively reviewed. The risk of developing high-grade cervical intraepithelial neoplasia (CIN2+) was assessed using Kaplan-Meier and Cox models. Data of 86 women were retrieved. Mean (standard deviation [SD]) age was 36.3 (13.4) years. A total of 71 (82.5%) patients had high-risk human papillomavirus (HR-HPV) at the time of diagnosis. Among the 63 patients undergoing repetition of HPV testing, 15 (24%) and 48 (76%) women had positive and negative tests for HR-HPV at 12 months, respectively. We observed that 5 (33%) of 15 patients with HPV persistence developed CIN2+, while only 1 (2%) patient of 48 patients without HPV persistence developed CIN2+ (odds ratio [OR]: 23.5; 95% confidence interval [CI]: 2.46-223.7; P < .001). The length of HR-HPV persistence correlated with an increased risk of developing CIN2+ ( P < .001; P for trend). High-risk HPV persistence is the only factor predicting for CIN2+ (hazard ratio: 3.19; 95% CI: 1.55-6.57; P = .002). High-risk HPV persistence predicts the risk of developing CIN2+ in patients with unsatisfactory colposcopic examination. Further studies are warranted in order to implement the use of HPV testing in patients with unsatisfactory colposcopy.

With proper logistical support and sponsorship, a laboratory in an industrialized nation might be able to act as a reference laboratory for clinicians based in a developing country. We built on previous experience in the clinical laboratory to see whether a specialized histopathology service (hematopathology) could be provided to a developing country without the expertise or experience to do it in country. Over an 13-year period, 582 cases from 579 individuals were analyzed. Principal pathologic findings included acute leukemia in 84 cases (14%), dyspoiesis in one or more of the hematopoietic lineages in 65 cases (11%, including three cases with high-grade myelodysplasia), 23 cases (4%) with findings suspicious for a chronic myeloproliferative disorder, 35 cases (6%) with findings suspicious for a lymphoproliferative disorder, and infectious organisms (presumably Leishmania in most instances) in 9 (1%) of cases. Specimens from 45 cases (8%) were unsatisfactory owing to extreme hemodilution and/or specimen degeneration. With proper support, a medical laboratory in an industrialized nation may serve as a reference facility for a developing nation. The use of existing infrastructure may be remarkably effective to achieve optimal turnaround time. Although the lack of ancillary studies and follow-up biopsies limit the ability to achieve a definitive diagnosis in many cases, this must be viewed in the context of the limited ability to diagnose or manage hematopoietic neoplasia in developing nations. © 2012 Blackwell Publishing Ltd.

Studies on the comparability of the results from different methods for the radioimmunological determination of digoxin

International Nuclear Information System (INIS)

Dwenger, A.; Trautschold, I.

1978-01-01

Three iodine-125-digoxin radioimmunoassay kits (A Amersham Buchler; B Boehringer Mannheim; C Schwarz Mann/Becton Dickinson) were evaluated with respect to assay quality and comparability of the results. Intra- and interassay variances were calculated for the following types of samples: Three media (a pool serum; b artificial human serum; c buffer solution with albumin and globulin) containing pure digoxin, sera from a pharmacokinetic study, sera with different concentrations of proteins, a hemolytic serum and sera with digitoxin and metabolites of spironolactone. The intra-assay precision depended on the medium of the sample and was higher for samples with identical digoxin concentrations in an identical medium (e.g. CV for 2 μg/l in medium a for kit A: 4.3% for kit B: 7.0%; for kit C: 2.2%) than for samples with identical antigen concentrations in different media (CV for 2 μg/l in media a, b and c for kit A: 6.4%; for kit B: 9.1%; for kit C: 4.3%). The mean recovery in the range 0.5-4 μg/l depended on the kind of medium (a, b or c) and varied for kit A from 84.4% to 100.8%, for kit B from 112.0% to 119.6%, and for kit C from 98.0% to 104.5%. Decreasing serum protein concentrations to less than one half of the physiological concentration gave false negative results for kit A and fals positive results for kit C; for kit B this dependency was not be observed, but there was a decrease of reproducibility.

A gradient estimate for solutions to parabolic equations with discontinuous coefficients

Directory of Open Access Journals (Sweden)

Jishan Fan

2013-04-01

Full Text Available Li-Vogelius and Li-Nirenberg gave a gradient estimate for solutions of strongly elliptic equations and systems of divergence forms with piecewise smooth coefficients, respectively. The discontinuities of the coefficients are assumed to be given by manifolds of codimension 1, which we called them emph{manifolds of discontinuities}. Their gradient estimate is independent of the distances between manifolds of discontinuities. In this paper, we gave a parabolic version of their results. That is, we gave a gradient estimate for parabolic equations of divergence forms with piecewise smooth coefficients. The coefficients are assumed to be independent of time and their discontinuities are likewise the previous elliptic equations. As an application of this estimate, we also gave a pointwise gradient estimate for the fundamental solution of a parabolic operator with piecewise smooth coefficients. Both gradient estimates are independent of the distances between manifolds of discontinuities.

Contrasting results from GWAS and QTL mapping on wing length in great reed warblers.

A major goal in evolutionary biology is to understand the genetic basis of adaptive traits. In migratory birds, wing morphology is such a trait. Our previous work on the great reed warbler (Acrocephalus arundinaceus) shows that wing length is highly heritable and under sexually antagonistic selection. Moreover, a quantitative trait locus (QTL) mapping analysis detected a pronounced QTL for wing length on chromosome 2, suggesting that wing morphology is partly controlled by genes with large effects. Here, we re-evaluate the genetic basis of wing length in great reed warblers using a genomewide association study (GWAS) approach based on restriction site-associated DNA sequencing (RADseq) data. We use GWAS models that account for relatedness between individuals and include covariates (sex, age and tarsus length). The resulting association landscape was flat with no peaks on chromosome 2 or elsewhere, which is in line with expectations for polygenic traits. Analysis of the distribution of p-values did not reveal biases, and the inflation factor was low. Effect sizes were however not uniformly distributed on some chromosomes, and the Z chromosome had weaker associations than autosomes. The level of linkage disequilibrium (LD) in the population decayed to background levels within c. 1 kbp. There could be several reasons to why our QTL study and GWAS gave contrasting results including differences in how associations are modelled (cosegregation in pedigree vs. LD associations), how covariates are accounted for in the models, type of marker used (multi- vs. biallelic), difference in power or a combination of these. Our study highlights that the genetic architecture even of highly heritable traits is difficult to characterize in wild populations. © 2018 John Wiley & Sons Ltd.

Kandias, D.; Bundjali, B.; Wahyuningrum, D.

2011-01-01

The corrosion inhibitor of carbon steel in 1 % NaCl solution by curcuminoids has been studied at 27 degree Celsius using weight loss and electrochemical method. The determination of corrosion inhibition efficiency (% eff) utilising weight loss method at the concentration of 80 ppm showed the best result of 78.70 % for third isolated fraction. Further determination utilising Tafel method showed the following results: raw pure extract of curcuminoid gave 89.88 % at 50 ppm; the first isolated fraction gave 46.50 % at 80 ppm; the second isolated fraction gave 44.83 % at 30 ppm; and the third isolated fraction gave 92.44 % at 70 ppm. Based on the analysis of Tafel extrapolation curve, the raw pure extract and the third fraction of curcuminoid acted as anodic inhibitor, whereas the first and the second fraction performed as cathodic inhibitors. The evaluations of synergism parameter (S θ ) indicate that the enhancement in inhibition efficiency towards raw pure extract was caused by the presence of second and third fractions as cathodic and anodic inhibitors. The contribution of steric hindrance of methoxy groups in curcuminoid structure causes the decrease in curcuminoid activity to be adsorbed on the electrode (carbon steel) surface. (author)

Full Text Available Introduction. Cervical cancer can be prevented by early diagnosis and treatment of patients with abnormal results, thus decreasing their incidence and mortality. In contrast to conventional techniques (Papanicolau, diagnostic techniques have been developed based on the preservation of the sample in a stabilizing solution (liquid-based cytology. The different methods of liquid-based cytology used in the screening of cervical cancer against the Papanicolau technique are evaluated. Material and methods. A systematic review of the literature has been performed (2010-2015. The search was developed by including MeSH terms as cervical intraepithelial neoplasia and papilloma virus infection in the MedLine, Embase, Cochrane Library, CRD, LILACS and IBECS databases. Inclusion criteria were adult women screened for cervical cancer using liquid-based cytology techniques, compared with conventional methods. Results. 464 references were found related to the reliability-precision of the test, of which 13 were included in the report. A health technology assessment report was conducted in 2013 by the Agency for Health Technology Assessment of Andalusia (AETSA. The quality of the studies was moderate and moderate-low. AETSA found studies that included more than 700,000 women between 14 and 90 years old, who were screened by liquid-based cytology, compared to the conventional one. Studies have shown that liquid-based cytology techniques reduce the percentage of unsatisfactory samples compared to conventional ones. The analysis of detection of cellular abnormalities and diagnostic validity indexes showed significant differences when comparing both methods. Conclusions. The studies analyzed presented methodological limitations. Hence, the results should be interpreted with caution. Liquid-based cytology did not present greater diagnostic capacity than conventional methods, but it reduced, with statistically significant results, the number of samples unsatisfactory

Objective To compare the accuracy of liquid based cytology using the computerised ThinPrep Imager with that of manually read conventional cytology. Design Prospective study. Setting Pathology laboratory in Sydney, Australia. Participants 55 164 split sample pairs (liquid based sample collected after conventional sample from one collection) from consecutive samples of women choosing both types of cytology and whose specimens were examined between August 2004 and June 2005. Main outcome measures Primary outcome was accuracy of slides for detecting squamous lesions. Secondary outcomes were rate of unsatisfactory slides, distribution of squamous cytological classifications, and accuracy of detecting glandular lesions. Results Fewer unsatisfactory slides were found for imager read cytology than for conventional cytology (1.8% v 3.1%; Pcytology (7.4% v 6.0% overall and 2.8% v 2.2% for cervical intraepithelial neoplasia of grade 1 or higher). Among 550 patients in whom imager read cytology was cervical intraepithelial neoplasia grade 1 or higher and conventional cytology was less severe than grade 1, 133 of 380 biopsy samples taken were high grade histology. Among 294 patients in whom imager read cytology was less severe than cervical intraepithelial neoplasia grade 1 and conventional cytology was grade 1 or higher, 62 of 210 biopsy samples taken were high grade histology. Imager read cytology therefore detected 71 more cases of high grade histology than did conventional cytology, resulting from 170 more biopsies. Similar results were found when one pathologist reread the slides, masked to cytology results. Conclusion The ThinPrep Imager detects 1.29 more cases of histological high grade squamous disease per 1000 women screened than conventional cytology, with cervical intraepithelial neoplasia grade 1 as the threshold for referral to colposcopy. More imager read slides than conventional slides were satisfactory for examination and more contained low grade cytological

ASSERT and COBRA predictions of flow distribution in vertical bundles

International Nuclear Information System (INIS)

Tahir, A.; Carver, M.B.

1983-01-01

COBRA and ASSERT are subchannel codes which compute flow and enthalpy distributions in rod bundles. COBRA is a well known code, ASSERT is under development at CRNL. This paper gives a comparison of the two codes with boiling experiments in vertical seven rod bundles. ASSERT predictions of the void distribution are shown to be in good agreement with reported experimental results, while COBRA predictions are unsatisfactory. The mixing models in both COBRA and ASSERT are briefly discussed. The reasons for the failure of COBRA-IV and the success of ASSERT in simulating the experiments are highlighted

Full Text Available A 25-year-old man was diagnosised subcutaneous panniculitis-like T-cell lymphoma (SPTCL through biopsy of a nodule from the anterior chest. After the treatment with prednisone 90 mg 3 weeks and tapered off in 1 month, the disease released, but relapsed together with symptions of hemophagocytic syndrome eight months after the termination of prednisone. CHOEP recipe was given but with unsatisfactory result until cyclosporine was prescribed. Cyclosporine was removed 6 months later. There is no evidence of clinical relapse 1 year later. This case suggest that cyclosporine could be a selectable treatment even in relapsed SPTCL.

Field theories on supermanifolds: general formalism, local supersymmetry, and the limit of global supersymmetry

International Nuclear Information System (INIS)

Bruzzo, V.

1986-01-01

This paper reports briefly on recent investigations concerning the formulation of field theories on supermanifolds. The usual formulations are unsatisfactory from a mathematical viewpoint, hence, this report. A variational theory for fields on a supermanifold is described where the action is a map between Banach spaces. The relationship between the field theory on the supermanifold and a suitably constructed field theory on space-time is also discussed. On-shell local supersymmetry are examined and the limit of global (rigid) supersymmetry is considered. A specific example is given which shows that the limit reproduces the known results

Albarracin, Dolores; Wang, Wei; Leeper, Joshua

2009-07-01

Communications to stimulate weight loss include exercise-promotion messages that often produce unsatisfactory results due to compensatory behavioral and metabolic mechanisms triggered by physical activity. This research investigated potential automatic facilitation of eating immediately after exercise messages in the absence of actual exercise. Two controlled experiments demonstrated greater than control food intake following exposure to print messages typical of exercise campaigns as well as subliminal presentation of action words associated with exercise (e.g., "active"). These inadvertent effects may explain the limited efficacy of exercise-promotion programs for weight loss, particularly when systematic dietary guidelines are absent.

Because the distal arteries of lower extremities become narrowed or even occluded in diabetic foot, the clinical therapeutic results for diabetic foot have been unsatisfactory so far. Autologous stem cell transplantation that has emerged in recent years is a new, safe and effective therapy for diabetic foot, which achieves its excellent clinical success in restoring the blood supply of ischemic limb by way of therapeutic angiogenesis. Now autologous stem cell transplantation has become one of the hot points in medical research both at home and abroad, moreover, it has brought a new hope of cure to the patients with diabetic foot.

Huang, Chun-Ming; Huang, Jen-Fa; Yang, Chao-Chin

2010-10-01

One extended Welch-Costas (EWC) code family for the wavelength-division-multiplexing/spectral-amplitude coding (WDM/SAC; WS) optical code-division multiple-access (OCDMA) networks is proposed. This system has a superior performance as compared to the previous modified quadratic congruence (MQC) coded OCDMA networks. However, since the performance of such a network is unsatisfactory when the data bit rate is higher, one class of quasi-cyclic low-density parity-check (QC-LDPC) code is adopted to improve that. Simulation results show that the performance of the high-speed WS-EWC coded OCDMA network can be greatly improved by using the LDPC codes.

Simultaneous viscous-inviscid coupling via transpiration

International Nuclear Information System (INIS)

Yiu, K.F.C.; Giles, M.B.

1995-01-01

In viscous-inviscid coupling analysis, the direct coupling technique and the inverse coupling technique are commonly adopted. However, stability and convergence of the algorithms derived are usually very unsatisfactory. Here, by using the transpiration technique to simulate the effect of the displacement thickness, a new simultaneous coupling method is derived. The integral boundary layer equations and the full potential equation are chosen to be the viscous-inviscid coupled system. After discretization, the Newton-Raphson technique is proposed to solve the coupled nonlinear system. Several numerical results are used to demonstrate the accuracy and efficiency of the proposed method. 15 refs., 23 figs

Context Matters: Distinct Disease Outcomes as a Result of Crebbp Hemizygosity in Different Mouse Bone Marrow Compartments.

Directory of Open Access Journals (Sweden)

Ting Zhou

Full Text Available Perturbations in CREB binding protein (CREBBP are associated with hematopoietic malignancies, including myelodysplastic syndrome (MDS. Mice hemizygous for Crebbp develop myelodysplasia with proliferative features, reminiscent of human MDS/myeloproliferative neoplasm-unclassifiable (MDS/MPN-U, and a proportion goes on to develop acute myeloid leukemia (AML. We have also shown that the Crebbp+/- non-hematopoietic bone marrow microenvironment induces excessive myeloproliferation of wild-type cells. We now report that transplantation of unfractionated Crebbp+/- bone marrow into wild-type recipients resulted in either early-onset AML or late-onset MDS and MDS/MPN-U. In contrast, purified Lin-Sca-1+c-Kit++ cells primarily gave rise to MDS with occasional transformation to AML. Furthermore, Crebbp+/- common myeloid progenitors and granulocyte/macrophage progenitors could trigger skewed myelopoiesis, myelodysplasia and late-onset AML. Surprisingly, the phenotypically abnormal cells were all of wild-type origin. MDS, MPN and AML can thus all be transferred from Crebbp+/- BM to wild-type hosts but fractionated bone marrow does not recapitulate the full disease spectrum of whole bone marrow, indicating that not only mutational status but also cellular context contribute to disease outcome. This has important consequences for structuring and interpreting future investigations into the underlying mechanisms of myeloid malignancies as well as for their treatment.

Patrícia Corrêa-Faria

Full Text Available The aim of this study was to assess the prevalence of early childhood caries (ECC in children and investigate the influence of sociodemographic variables, quality of oral hygiene and child-related aspects. A cross-sectional study was carried out with 593 children aged three to five years. Data were collected through clinical examinations and interviews with parents. Interviews with parents of the children were conducted to acquire information on sociodemographic aspects, breastfeeding, bottle feeding and harmful oral habits. Statistical analysis involved the chi-square test and the Poisson regression. The prevalence of ECC was 53.6%. The occurrence of ECC was greater among children with unsatisfactory oral hygiene (PR: 2.95; 95% CI: 2.42-3.60 and those from a family with a lower monthly household income (PR: 1.62; 95% CI: 1.24-2.10. In conclusion, unsatisfactory oral hygiene and monthly income exerted an influence on the occurrence of ECC among preschoolers.

Radial forearm free flap for soft palate reconstruction.

Science.gov (United States)

Lacombe, V; Blackwell, K E

1999-01-01

Defects of the soft palate resulting from head and neck oncologic surgery traditionally have been rehabilitated using a prosthetic obturator. In general, the results of soft palate obturation have been satisfactory, with most patients achieving velopharyngeal competence during speech and swallowing. However, soft palate obturators have several disadvantages. Device stability and retention are impaired in patients who are edentulous. In addition, prosthetic obturators cover large areas of sensate mucosa in the hard palate, maxillary alveolus, and oropharynx, contributing significantly to the loss of sensory feedback from the oral cavity and oropharynx. Considerable evidence suggests that sensory impairment within the oral cavity and pharynx results in impaired mastication, deglutition, and articulation. A minority of patients find palatal obturators to be unsatisfactory, secondary to either inconvenience or device discomfort.

2015-04-01

Effective communication in dairy farms improves management and herd health, and it is also pivotal for public health in a "from farm to fork" perspective. This paper reports the results of a descriptive study on dairy farmers' perception of veterinarian and other consultants' communication skills. Perceived communication skills showed to be significantly lower than desired ones for all the professional figures considered. Despite these unsatisfactory results, veterinarian were the most appreciated and skilled consultants. The observed farmers' dissatisfaction increases farmers' difficulties in identifying proper targets and proper consultant. An increase in the skill of veterinarian to deliver effective and tailored messages could help to overcome the problem. Copyright © 2015 Elsevier Ltd. All rights reserved.

Full Text Available Background: ThinPrep® (TP cervical cytology, as a liquid-based method, has many benefits but also a relatively high unsatisfactory rate due to debris/lubricant contamination and the presence of blood. These contaminants clog the TP filter and prevent the deposition of adequate diagnostic cells on the slide. An acetic acid wash (AAW protocol is often used to lyse red blood cells, before preparing the TP slides. Design: From 23,291 TP cervical cytology specimens over a 4-month period, 2739 underwent AAW protocol due to initial unsatisfactory smear (UNS with scant cellularity due to blood or being grossly bloody. Randomly selected 2739 cervical cytology specimens which did not undergo AAW from the same time period formed the control (non-AAW group. Cytopathologic interpretations of AAW and non-AAW groups were compared using the Chi-square test. Results: About 94.2% of the 2739 cases which underwent AAW were subsequently satisfactory for evaluation with interpretations of atypical squamous cells of undetermined significance (ASCUS 4.9% (135, low-grade squamous intraepithelial lesions (LSIL 3.7% (102, and high-grade squamous intraepithelial lesions (HSIL 1% (28. From the 2739 control cases, 96.3% were satisfactory with ASCUS 5.5% (151, LSIL 5.1% (139, and HSIL 0.7% (19. The prevalence of ASCUS interpretations was similar (P = 0.33. Although there were 32% more HSIL interpretations in the AAW group (28 in AAW vs. 19 in non-AAW, the difference was statistically insignificant (P = 0.18. AAW category; however, had significantly fewer LSIL interpretations (P = 0.02. The percentage of UNS cases remained higher in the AAW group with statistical significance (P < 0.01. Conclusions: While AAW had a significantly higher percent of UNS interpretations, the protocol was effective in rescuing 94.2% of specimens which otherwise may have been reported unsatisfactory. This improved patient care by avoiding a repeat test. The prevalence of ASCUS and HSIL

In the vibration analysis for the aseismatic design of reactor facilities, various attenuation theories have been used case by case. In this study, three attenuation theories of internal viscosity type, strain energy type and kinetic energy type were applied to the vibration analysis for a BWR type reactor building, and the respective results were compared. The three theories are explained briefly. Different damping factors were taken for the RC building, steel internal equipments and ground. The reactor building for a BWR of Mark 1 type was studied, and the mathematic vibration model involving those for the building, shield wall, primary containment vessel, gamma shield wall, reactor pressure vessel and foundation is shown. Natural frequency analysis, frequency response analysis and earthquake response analysis were carried out. Regarding the response of the building, the internal viscosity type and the strain energy type gave almost same values, but the kinetic energy type gave the value 1.2 times as large as the former values. In the response of the building, the first mode element is predominant, and the damping factors to the first mode caused these results. Regarding the maximum response acceleration and floor response spectra of internal equipments, the strain energy type and the kinetic energy type gave similar results, and the internal viscosity type gave smaller values.

Minerals play a key role in controlling the mobility and distribution of metals and metalloids of environmental concern in supergenic environments. These are involved in a variety of processes, spanning the alteration of primary minerals to the formation of secondary authigenic phases and can represent a source or a trap for Potentially Ecotoxic Elements (PTEs). Soil, sediments, and waters heavily polluted with PTEs through AMD processes are a reservoir of a unusual bacteria and fungi well adapted to these toxic environments. Classical studies of biotic weathering have mainly focused on water-mineral interaction and on the ability of microorganism to influence the soil solution chemical composition. In this work, we analyzed two different representative ochreous and greenish-blue AMD colloidal precipitates in order to i) characterize the biota population present in these colloidal minerals and ii) verify the bioaccumulation of PTEs into the fungi and the potential impact of bacteria in the geochemistry of the system. The samples are composed by nanocrystalline goethite which contains high amounts of Fe, Cu, Zn, Pb, and Ni and woodwardite that is characterized by Cu, Zn, Ni, Y, and Ce. These precipitates were examined in order to evaluate the presence of fungal strains and to extract bacteria DNA. The preliminary results of fungi characterization show an interesting and selected mycobiota able to survive under unfavourable environmental conditions. A significant number of fungal strains was isolated in pure culture. Most of them belong to the genus Mucor and Penicillium. It is worth noting the presence of Trametes versicolor, a macrofungal lignicolous species already known for heavy metal biosorption capability from aqueous solution (Gülay et al 2003). The same colloidal precipitates have been processed to extract bacteria DNA, using a specific procedure developed for DNA extraction from sediments. The results gave a good yield of nucleic acids and the positive PCR

This planting was made to test the adaptability of the Hevea plant to a low elevation area near the Serra do Mar range, located at 24°10' south. Growth of the Hevea plants in this experimental planting was fair, but yield data obtained by means of the Morris-Mann test indicated that it was rather low. The unsatisfactory growth as well as the poor yield are attributed to the poor handling of the rubber planting rather than to an unfavorable effect of the environment.

We performed multipoint linkage analyses with multiple programs and models for several gene expression traits in the Centre d'Etude du Polymorphisme Humain families. All analyses provided consistent results for both peak location and shape. Variance-components (VC) analysis gave wider peaks and Bayes factors gave fewer peaks. Among programs from the MORGAN package, lm_multiple performed better than lm_markers, resulting in less Markov-chain Monte Carlo (MCMC) variability between runs, and the program lm_twoqtl provided higher LOD scores by also including either a polygenic component or an additional quantitative trait locus.

Renal PatientView (RPV) is a novel, web-based system in the UK that provides patients with access to their laboratory results, in conjunction with patient information. To study how renal patients within our centre access and use RPV. We sent out questionnaires in December 2011 to all 651 RPV users under our care. We collected information on aspects such as the frequency and timing of RPV usage, the parameters viewed by users, and the impact of RPV on their care. A total of 295 (45 %) questionnaires were returned. The predominant users of RPV were transplant patients (42 %) followed by pre-dialysis chronic kidney disease patients (37 %). Forty-two percent of RPV users accessed their results after their clinic appointments, 38 % prior to visiting the clinic. The majority of patients (76 %) had used the system to discuss treatment with their renal physician, while 20 % of patients gave permission to other members of their family to use RPV to monitor results on their behalf. Most users (78 %) reported accessing RPV on average 1-5 times/month. Most patients used RPV to monitor their kidney function, 81 % to check creatinine levels, 57 % to check potassium results. Ninety-two percent of patients found RPV easy to use and 93 % felt that overall the system helps them in taking care of their condition; 53 % of patients reported high satisfaction with RPV. Our results provide interesting insight into use of a system that gives patients web-based access to laboratory results. The fact that 20 % of patients delegate access to relatives also warrants further study. We propose that online access to laboratory results should be offered to all renal patients, although clinicians need to be mindful of the 'digital divide', i.e. part of the population that is not amenable to IT-based strategies for patient empowerment.

To compare the health status and factors influencing the health of populations that had previously lived under different political systems. Cross sectional health and social survey using postal interviews. The relation between self reported health and psychosocial factors (stressful life events, social support, education, health promoting life style and health endangering behaviour) was investigated. To determine East-West differences a logistic regression model including interaction terms was fitted. East and West Berlin shortly after reunification 1991. Representative sample of 4430 Berlin residents aged 18 years and over (response rate 63%). Of all respondents, 15.4% rated their health as unsatisfactory. Residents of East Berlin rated their health more frequently as unsatisfactory than residents of West Berlin (Or(age adjusted)= 1.29, 95%CI 1.08, 1.52), these differences occurred predominantly in the over 60 years age group. Logistic regression showed significant independent effects of stressful life events, social support, education, and health promoting life style on self rated health. The effects of education and health promoting life style were observed to be more pronounced in the western part of Berlin. Old age and female sex showed a stronger association with unsatisfactory health status in the eastern part of Berlin. For subjects aged over 60 years there was evidence that living in the former East Berlin had an adverse effect on health compared with West Berlin. The impact of education and a health promoting lifestyle on self rated health seemed to be weaker in a former socialist society compared with that of a Western democracy. This study supports an "additive model" rather than a "buffering model" in explaining the effects of psychosocial factors on health.

Well-defined protocols and quality management standards are indispensable for biological dosimetry laboratories. Participation in periodic proficiency testing by interlaboratory comparisons is also required. This harmonization is essential if a cooperative network is used to respond to a mass casualty event. Here we present an international intercomparison based on dicentric chromosome analysis for dose assessment performed in the framework of the IAEA Regional Latin American RLA/9/054 Project. The exercise involved 14 laboratories, 8 from Latin America and 6 from Europe. The performance of each laboratory and the reproducibility of the exercise were evaluated using robust methods described in ISO standards. The study was based on the analysis of slides from samples irradiated with 0.75 (DI) and 2.5 Gy (DII). Laboratories were required to score the frequency of dicentrics and convert them to estimated doses, using their own dose-effect curves, after the analysis of 50 or 100 cells (triage mode) and after conventional scoring of 500 cells or 100 dicentrics. In the conventional scoring, at both doses, all reported frequencies were considered as satisfactory, and two reported doses were considered as questionable. The analysis of the data dispersion among the dicentric frequencies and among doses indicated a better reproducibility for estimated doses (15.6% for DI and 8.8% for DII) than for frequencies (24.4% for DI and 11.4% for DII), expressed by the coefficient of variation. In the two triage modes, although robust analysis classified some reported frequencies or doses as unsatisfactory or questionable, all estimated doses were in agreement with the accepted error of ±0.5 Gy. However, at the DI dose and for 50 scored cells, 5 out of the 14 reported confidence intervals that included zero dose and could be interpreted as false negatives. This improved with 100 cells, where only one confidence interval included zero dose. At the DII dose, all estimations fell within
