Manipulating the Alpha Level Cannot Cure Significance Testing

Full Text Available We argue that making accept/reject decisions on scientific hypotheses, including a recent call for changing the canonical alpha level from p = 0.05 to p = 0.005, is deleterious for the finding of new discoveries and the progress of science. Given that blanket and variable alpha levels both are problematic, it is sensible to dispense with significance testing altogether. There are alternatives that address study design and sample size much more directly than significance testing does; but none of the statistical tools should be taken as the new magic method giving clear-cut mechanical answers. Inference should not be based on single studies at all, but on cumulative evidence from multiple independent studies. When evaluating the strength of the evidence, we should consider, for example, auxiliary assumptions, the strength of the experimental design, and implications for applications. To boil all this down to a binary decision based on a p-value threshold of 0.05, 0.01, 0.005, or anything else, is not acceptable.

Dual cusped protostylid: Case report and clinical significance

Full Text Available Protostylids are superstructures on maxillary or mandibular molars, which have rarely been reported in literature, and the significance of their presence has also been underestimated. The dental practitioners may easily misdiagnose a tooth, with such conical tubercles as malformed tooth. Interestingly, this is neither a malformation nor an anomaly but rather an important morphological trait of an individual. Once in a while, one may come across such a distinct morphological trait without being able to diagnose. To the authors' best knowledge, only one similar case has been reported previously, and the second such case internationally. Bearing all such facts in mind, the authors attempt to educate the readers towards the existence of such a trait so that it can be identified and studied in larger numbers. Hence, it is the authors' endeavor to report an unusual case of dual cusped maxillary protostylid along with its clinical significance.

Cermets are being developed as an alternate method for the fixation of defense and commercial high level radioactive waste in a terminal disposal form. Following initial feasibility assessments of this waste form, consisting of ceramic particles dispersed in an iron-nickel base alloy, significantly improved processing methods were developed. The characterization of cermets has continued through property determinations on samples prepared by various methods from a variety of simulated and actual high-level wastes. This report describes the status of development of the cermet waste form as it has evolved since 1977. 6 tables, 18 figures

Different measures of non-adherence to immunosuppressant (IS) medication have been found to be associated with rejection episodes after successful transplantation. The aim of the current study was to investigate whether graft rejection after renal transplantation is associated with patient-reported IS medication non-adherence and IS trough level variables (IS trough level variability and percentage of sub-therapeutic IS trough levels). Patient-reported non-adherence, IS trough level variability, percentage of sub-therapeutic IS trough levels, and acute biopsy-proven late allograft rejections were assessed in 267 adult renal transplant recipients who were ≥12 months post-transplantation. The rate of rejection was 13.5%. IS trough level variability, percentage of sub-therapeutic IS trough levels as well as patient-reported non-adherence were all significantly and positively associated with rejection, but not with each other. Logistic regression analyses revealed that only the percentage of sub-therapeutic IS trough levels and age at transplantation remained significantly associated with rejection. Particularly, the percentage of sub-therapeutic IS trough levels is associated with acute rejections after kidney transplantation whereas IS trough level variability and patient-reported non-adherence seem to be of subordinate importance. Patient-reported non-adherence and IS trough level variables were not correlated; thus, non-adherence should always be measured in a multi-methodological approach. Further research concerning the best combination of non-adherence measures is needed.

To investigate the correlation of Vascular Endothelial Growth Factor (VEGF) and micro-vessel density (MVD) with urinary bladder tumor and its stage. The study was conducted between January 2010 and December 2012. The study included screening of 122 patients at elevated risk for bladder cancer, of which 35 patients were finally enrolled in the study. Diagnosis was made on the basis of urine cytology, radiological investigation (ultrasound KUB, and CT-scan) and histopathology. Thirty-five normal cancer-free individuals were enrolled as controls. Human VEGF levels were measured using an enzyme linked immunoassay and protein content (pg/mg protein) by Lowry method. SPSS for Windows version 10.0.7 (SPSS, Chicago, IL, USA) was used for statistical analysis of the data. Mean urine VEGF level in the cases was significantly higher in comparison to the control group. There was a direct correlation between VEGF level and tumor stage. Mean urine VEGF values were minimum in the control group (22.75 ± 15.41 pg/mg creatinine) and maximum in stage IV patients (180.15 ± 75.93 pg/mg creatinine). Tissue VEGF levels also showed a similar trend of increase with increase in stage. Urine VEGF level also showed a correlation with tissue VEGF level. Similarly, MVD showed a significant increase with increase in tumor stage. A correlation between bladder cancer and MVD and VEGF suggest that the latter can serve as markers for therapeutic guidance. This is the first study from India on clinical and pathological correlation among urine VEGF, tumor tissue VEGF levels, and Micro Vessel Density (MVD) in urinary bladder cancer patients.

The aim of this study is to examine the plasma endocan level and its prognostic significance in newly diagnosed breast cancer patients. Methods: A total of 84 patients were enrolled the study. Plasma endocan level was measured by specific enzyme-linked immunosorbent assay (ELİSA kit. Ethical approval and informed consent were attained. Results: At the time of diagnosis, 33 patients had stage 4 disease. The median plasma endocan level was 619.9 (min 259.9–2813.2 ng/L and its level was significantly higher in metastatic breast cancer group compared to non–metastatic breast cancer group. According to molecular sub-type of breast cancer, there is not statistical difference in plasma endocan level, but its level was higher in patients with Her-2 amplified and triple negative breast cancer (TNBC. Median follow-up time is 11 (1-30 months. Event free survival (EFS was 15 months in patients with plasma endocan level lower than 620, while it was 4 months in patients with serum endocan level greater than 620 (p = 0.016. There was no difference between groups in terms of hypertension, age, Lymphovascular invasion (LVI, extra capsular extension (ECE, body mass index (BMI and White blood cells (WBC, platelet count and plasma endocan level. Conclusion: Plasma endocan levels higher than non metastatic breast cancer. Patients with high plasma endocan levels are short EFS. Further studies would be useful to assess endocan level as a prognostic factor in breast cancer. Keywords: Endothelial cell specific molecule, Breast cancer, Prognosis

Marcelo Teodoro Ezequiel Guerra

Full Text Available ABSTRACT OBJECTIVE: To compare serum 25-hydroxyvitamin D (25[OH]D levels, a serum marker of vitamin D3, between patients with and without proximal hip fracture. METHODS: This was a case-control study in which serum samples of 25(OHD were obtained from 110 proximal hip fracture inpatients and 231 control patients without fractures, all over 60 years of age. Levels of 25(OHD lower than or equal to 20 ng/mL were considered deficient; from 21 ng/mL to 29 ng/mL, insufficient; and above 30 ng/mL, sufficient. Sex, age, and ethnicity were considered for association with the study groups and 25(OHD levels. RESULTS: Patients with proximal hip fracture had significantly lower serum 25(OHD levels (21.07 ng/mL than controls (28.59 ng/mL; p = 0.000. Among patients with proximal hip fracture, 54.5% had deficient 25(OHD levels, 27.2% had insufficient levels, and only 18.2% had sufficient levels. In the control group, 30.3% of patients had deficient 25(OHD levels, 30.7% had insufficient levels, and 38.9% had sufficient levels. Female patients had decreased serum 25(OHD levels both in the fracture group and in the control group (19.50 ng/mL vs. 26.94 ng/mL; p = 0.000 when compared with male patients with and without fracture (25.67 ng/mL vs. 33.74 ng/mL; p = 0.017. Regarding age, there was a significant association between 25(OHD levels and risk of fracture only for the age groups 71-75 years and above 80 years. CONCLUSION: Patients with proximal hip fracture had significantly decreased serum 25(OHD levels when compared with the control group. Female patients had significantly lower serum 25(OHD levels in both groups.

To evaluate the significance of assay of serum thyroglobulin(Tg) in monitoring the course of the thyroid cancer or its response to treatment, serum thyroglobulin levels were measured in 41 patients with thyroid cancer who visited Seoul National University Hospital from August, 1981 to August, 1982. The results were as follows: 1) Serum Tg levels 1-3 months after thyroidectomy was 31±23 ng/ml(mean±S.D.) in 14 patients without metastasis, 66±41 ng/ml in 21 patients with regional metastasis and 176±59 ng/ml in 6 patients with distant metastasis and there were significant differences among three groups(p 131 I treatment were 134±62 ng/ml and 67±52 ng/ml respectively. 3) In the follow-up measurement of serum Tg levels every 3 months for about 1 year, almost all serum Tg levels were below 60 ng/ml in 12 patients without distant metastasis and serum Tg levels were elevated above 60 ng/ml in 5 of 6 patients with distant metastasis. 4) In 6 patients with distant metastasis, serum Tg levels were elevated in 5 patients and 131 I Whole body scan showed definite metastatic evidence in 3 patients and suspicious evidence in 1 patient. From above results, we concluded that serum Tg level is very useful as an indicator of recurrence or metastasis in patients with thyroid cancer after operation.

Objective: To investigate the clinical significance of the changes of serum cortisol and insulin levels in neonates with asphyxia. Methods: Serum cortisol levels were determined with CLIA and serum insulin levels with RIA in 38 neonates with asphyxia (mild degree 20, advanced 18) and 30 controls. Results: 1) In mild cases, serum insulin levels were significantly higher than those in controls (p<0.01) and serum cortisol levels were very significantly higher (p<0.001). 2) In advanced cases, both serum insulin and cortisol levels were very significantly higher than those in the controls (p<0.001). Conclusion: Hypoxia in the neonates with asphyxia is a very severe stress and will induce hypersecretion of cortisol and hyperglycemia which is detrimental to the patients. However hypersecretion of insulin will result in hypoglycemia, which is also very damaging. Physicians in charge should be aware of these possibilities and deal with them appropriately

Multi-level significance of vulnerability indicators. Case study: Eastern Romania

Vulnerability assessment aims, most frequently, to emphasize internal fragility of a system comparing to a reference standard, to similar systems or in relation to a given hazard. Internal fragility, either biophysical or structural, may affect the capacity to predict, to prepare for, to cope with or to recover from a disaster. Thus, vulnerability is linked to resilience and adaptive capacity. From local level to global one, vulnerability factors and corresponding indicators are different and their significance must be tested and validated in a well-structured conceptual and methodological framework. In this paper, the authors aim to show the real vulnerability of rural settlements in Eastern Romania in a multi-level approach. The research area, Tutova Hills, counts about 3421 sq.km and more than 200.000 inhabitants in 421 villages characterized by deficient accessibility, lack of endowments, subsistential agriculture, high pressure on natural environment (especially on forest and soil resources), poverty and aging process of population. Factors that could influence the vulnerability of these rural settlements have been inventoried and assigned into groups through a cluster analysis: habitat and technical urban facilities, infrastructure, economical, social and demographical indicators, environment quality, management of emergency situations etc. Firstly, the main difficulty was to convert qualitative variable in quantitative indicators and to standardize all values to make possible mathematical and statistical processing of data. Secondly, the great variability of vulnerability factors, their different measuring units and their high amplitude of variation require different method of standardization in order to obtain values between zero (minimum vulnerability) and one (maximum vulnerability). Final vulnerability indicators were selected and integrated in a general scheme, according to their significance resulted from an appropriate factor analysis: linear and

To determine the impact of specific reporting tasks on the performance of radiologists when reading chest radiographs. Ten experienced radiologists read a set of 40 postero-anterior (PA) chest radiographs: 21 nodule free and 19 with a proven solitary nodule. There were two reporting conditions: an unframed task (UFT) to report any abnormality and a framed task (FT) reporting only lung nodule/s. Jackknife free-response operating characteristic (JAFROC) figure of merit (FOM), specificity, location sensitivity and number of true positive (TP), false positive (FP), true negative (TN) and false negative (FN) decisions were used for analysis. JAFROC FOM for tasks showed a significant reduction in performance for framed tasks (P = 0.006) and an associated decrease in specificity (P = 0.011) but no alteration to the location sensitivity score. There was a significant increase in number of FP decisions made during framed versus unframed tasks for nodule-containing (P = 0.005) and nodule-free (P = 0.011) chest radiographs. No significant differences in TP were recorded. Radiologists report more FP decisions when given specific reporting instructions to search for nodules on chest radiographs. The relevance of clinical history supplied to radiologists is called into question and may induce a negative effect. (orig.)

2005-01-01

Objective: To study the clinical significance of post-operative changes of serum IL-18 levels in patients after renal transplantation. Methods: Serum IL-18 levels were detected with ELISA in 33 patients with renal transplantation before operation and repeated again on d5, d10 and d20 post-operatively as well as in 35 controls. Results: Pre-operatively, serum IL-18 levels in patients for upcoming renal transplantation were significantly higher than those in controls (P<0.01). After operation, the IL-18 levels on d5 and d10 in patients with acute rejection were not significantly changed from those pre-operatively but were markedly increased on d20 (vs pre-operative, d5, d10; all P<0.01). In the patients without rejection, levels in d5 were significantly higher than those pre-operatively, but dropped to approaching pre-operative values on d10 and d20. On d20, levels of serum IL-18 in patients with rejection were very significantly higher than those in stable patients (P<0.01). Conclusion: Serum IL-18 is a useful marker for identifying acute rejection. (authors)

Objectives: To determine the associations between serum cancer antigen 15-3 levels and prognostic factors in patients with endometrial carcinomas. Additionally, we investigated the clinical utility of serum cancer antigen 15-3 levels in the selection of low-risk patients with endometrioid type, tumor size <2 cm, myometrial invasion ≤50%, and histological grade 1-2. Methods: Ninety-six patients, who were surgically staged at Ankara Yildirim Beyazit University, Ankara, Turkey, between 2007 and 2016, were retrospectively analyzed. Demographic, clinical, and surgical characteristics were retrieved from the patients’ hospital records. A p<0.05 was considered significant. Results: Fifteen patients had advanced (≥Stage II) disease, 14 patients had Type 2 histology, 20 patients had Grade 3 tumors, 23 patients had lymphovascular space invasion, and 10 patients had positive lymph node involvement. Serum cancer antigen 15-3 levels were significantly higher in patients with advanced (≥Stage II) disease, Type 2 histology, Grade 3 tumors, lymp°hovascular space invasion, and positive lymph node involvement (p<0.05). Serum cancer antigen 15-3 levels were also significantly correlated with tumor size (p=0.006). Serum cancer antigen 15-3 levels were significantly lower (95% confidence interval: 0.57−0.79; p=0.03) in low-risk patients compared to other endometrial carcinoma patients. A cutoff of 25.0 IU/mL was used to identify high-risk patients with a specificity of 100%. Conclusion: Serum cancer antigen 15-3 levels significantly correlated with prognostic factors and were a useful diagnostic tool for endometrial carcinomas. PMID:29114696

Full Text Available Over diagnosis of acute rheumatic fever (ARF based on a raised antistreptolysin O titer (ASOT is not uncommon in endemic areas. In this study, 660 children (aged 9.2 ±1.7 years were recruited consecutively and classified as: G1 (control group, n=200 healthy children, G2 (n=20 with ARF 1st attack, G3 (n=40 with recurrent ARF, G4 (n=100 with rheumatic heart disease (RHD on long acting penicillin (LAP, G5 (n=100 with acute follicular tonsillitis, and G6 (n=200 healthy children with history of repeated follicular tonsillitis more than three times a year. Serum ASOT was measured by latex agglutination. Upper limit of normal (ULN ASOT (80th percentile was 400 IU in G1, 200 IU in G4, and 1600 IU in G6. Significantly high levels were seen in ARF 1st attack when compared to groups 1 and 5 (P<0.001 and P<0.05, respectively. ASOT was significantly high in children over ten years of age, during winter and in those with acute rheumatic carditis. ASOT showed significant direct correlation with the number of attacks of tonsillitis (P<0.05. Egyptian children have high ULN ASOT reaching 400 IU. This has to be taken into consideration when interpreting its values in suspected ARF. A rise in ASOT is less prominent in recurrent ARF compared to 1st attack, and acute and recurrent tonsillitis. Basal levels of ASOT increase with age but the pattern of increase during infection is not age dependent

Objective: To evaluate the significance of monitoring serum sex hormones levels after ovarian tissue auto-transplantation. Methods: Twenty-five patients with stage IV recurrent endometriosis after one or two times of conservative surgeries underwent radical surgery. Their ovarian tissue fragments were transplanted to greater omentum. Serum follicle-stimulation hormone (FSH), Luteinizing hormone (LH) and estradiol (E 2 ) levels were measured monthly since fourth month post-operatively. After E 2 was increased, based body temperature was measured and vaginal hormone cytology was examined weekly for maturation index (MI) to assess the ovulatory phase and luteal phase in those with viable ovarian tissues. Serum levels of FSH, LH and E 2 in ovulatory phase and luteal phase were determined 20 women with viable ovarian tissues for three cycles as well as in 20 normal sexually mature women and 20 operative menopausal women. Results: There were 12 cases who had increasing of E 2 at four months post operatively and 8 cases more at six months. The other 5 cases with low serum E 2 levels and high FSH and LH levels at 12 months were designated as failures. The survival rate of transplanted ovarian tissue was 80.0%. There were no significant differences of the serum FSH, LH and E 2 levels in ovulatory phase and luteal phase between women with viable grafted ovarian tissues and normal sexually mature women. Conclusion: Monitoring of sex hormones is a good means to assess the viability of the transplanted ovarian tissue fragments

Potential prognostic significance of decreased serum levels of TRAIL after acute myocardial infarction.

Directory of Open Access Journals (Sweden)

Paola Secchiero

Full Text Available BACKGROUND: Since soluble TRAIL exhibits anti-inflammatory and anti-atherosclerotic activities both in vitro and in animal models, this study was designed to assess the relationship between the serum levels of TRAIL and clinical outcomes in patients with acute myocardial infarction (AMI. METHODOLOGY/PRINCIPAL FINDINGS: Levels of TRAIL were measured by ELISA in serial serum samples obtained from 60 patients admitted for AMI, both during hospitalization and in a follow-up of 12 months, as well as in 60 healthy control subjects. Serum levels of TRAIL were significantly decreased in patients with AMI at baseline (within 24 hours from admission, compared with healthy controls, and showed a significant inverse correlation with a series of negative prognostic markers, such as CK, CK-MB and BNP. TRAIL serum levels progressively increased at discharge, but normalized only at 6-12 months after AMI. Of note, low TRAIL levels at the patient discharge were associated with increased incidence of cardiac death and heart failure in the 12-month follow-up, even after adjustment for demographic and clinical risk parameters (hazard ratio [HR] of 0.93 [95% CI, 0.89 to 0.97]; p = 0.001. CONCLUSIONS/SIGNIFICANCE: Although the number of patients studied was limited, our findings indicate for the first time that circulating TRAIL might represent an important predictor of cardiovascular events, independent of conventional risk markers.

High pretreatment levels of plasma fibrinogen have been widely reported to be a potential predictor of prognosis in digestive system tumors; however, the conclusions are not consistent. Therefore, we performed a meta-analysis to comprehensively assess the prognostic roles of high pretreatment plasma fibrinogen levels in digestive system tumors. We searched for eligible studies in the PubMed, Embase, and Web of Science electronic databases for publications from the database inception to 1 September 2017. The endpoints of interest included overall survival, disease-free survival, and recurrence-free survival. We investigated the relationship between fibrinogenemia and overall survival in colorectal cancer (10 studies), gastric cancer (6), pancreatic cancer (6), hepatocellular carcinoma (7), and esophageal squamous cell carcinoma (10); the pooled results indicated that fibrinogenemia was significantly related to a worse overall survival (hazard ratio (HR) 1.73; 95% confidence interval (CI) 1.52, 1.97; P digestive system tumors, indicating that it could be a useful prognostic marker in these types of tumors.

Towards a new paradigm: Activity level balanced sustainability reporting.

Technoeconomic paradigms based economic growth theories suggest that waves of technological innovations drove the economic growth of advanced economies. Widespread economic degradation and pollution is an unintended consequence of such growth. Tackling environmental and social issues at firm levels would help us to overcome such issues at macro-levels. Consequently, the Triple Bottom Line (TBL) reporting approach promotes firm level economic, environmental and social performances. Incorporating Zink's (2014) 3-pillar presentation model, this paper indicates that economic, social and environmental performances tend to be reported at firm level. All three pillars are not covered evenly at the activity levels. Thus, a loophole is identified whereby excellent environmental performance at activity levels could potentially leave poor social performance undisclosed. A refinement of the TBL paradigm, whereby all three pillars are covered at the activity level, is suggested, to enhance sustainability reporting. Copyright © 2016 Elsevier Ltd. All rights reserved.

Our objective was to assess the hypothesis that there are variations of the proportion of articles reporting a significant effect, with a higher percentage of those articles published in journals with impact factors. The contents of 5 orthodontic journals (American Journal of Orthodontics and Dentofacial Orthopedics, Angle Orthodontist, European Journal of Orthodontics, Journal of Orthodontics, and Orthodontics and Craniofacial Research), published between 2004 and 2008, were hand-searched. Articles with statistical analysis of data were included in the study and classified into 4 categories: behavior and psychology, biomaterials and biomechanics, diagnostic procedures and treatment, and craniofacial growth, morphology, and genetics. In total, 2622 articles were examined, with 1785 included in the analysis. Univariate and multivariate logistic regression analyses were applied with statistical significance as the dependent variable, and whether the journal had an impact factor, the subject, and the year were the independent predictors. A higher percentage of articles showed significant results relative to those without significant associations (on average, 88% vs 12%) for those journals. Overall, these journals published significantly more studies with significant results, ranging from 75% to 90% (P = 0.02). Multivariate modeling showed that journals with impact factors had a 100% increased probability of publishing a statistically significant result compared with journals with no impact factor (odds ratio [OR], 1.99; 95% CI, 1.19-3.31). Compared with articles on biomaterials and biomechanics, all other subject categories showed lower probabilities of significant results. Nonsignificant findings in behavior and psychology and diagnosis and treatment were 1.8 (OR, 1.75; 95% CI, 1.51-2.67) and 3.5 (OR, 3.50; 95% CI, 2.27-5.37) times more likely to be published, respectively. Journals seem to prefer reporting significant results; this might be because of authors

2006-01-01

Objective: To investigate the changes of serum BGP levels in different age-groups. Methods: Serum BGP levels were determined with RIA in 306 subjects of different age-groups. Results: The serum BGP levels were highest in subjects of the pre-adolescent group (age5-15, n=60, vs other groups, all P 50, n=80, P<0.001). Levels in the middle age group were the lowest and were significantly lower than those in the old age group (P<0.001). No sex related differences were observed in the pre-adolescent and middle age groups, but in the youth group, serum BGP levels were significantly higher in the males than those in the females (P<0.05). However, in the old age group, the reverse was true i.e. values being significantly higher in the females (vs males, P<0.01). Conclusion: Serum BGP levels varied greatly among the different age groups. (authors)

Objective: To study the clinical significance of changes of serum levels of TBA, CG, HA in neonate with parenteral nutrition. Methods: Serum total bile acid (TBA, with biochemistry) and CG, HA (with RIA) contents were measured in 52 neonates (full-term 32, preterm 20) with parenteral nutrition and 28 neonates (full-term 16, preterm 12) without parenteral nutrition (as controls). Results: Before parenteral nutrition,the serum TBA, CG and HA levels in full-term neonates were not significantly different from those in the controls (P>0.05). After parenteral nutrition,serum levels were significantly higher than those before parenteral nutrition (P<0.01). The levels in pre-term neonates were significantly higher after parenteral nutrition than those in full-term neonates (P<0.05). Conclusion: Long term parenteral nutrition might be harmful to hepatic and gall bladder function in neonates especially in premature ones. (authors)

In order to evaluate the clinical significances of the serum vitamin B 12 , folate and ferritin levels in patients with malignant tumors, the levels were measured in 10 normal control subjects, 70 patients with malignant tumors, 7 patients with liver cirrhosis and 25 patients with other benign diseases. The results are as follows: 1) In normal control subjects, mean serum values for vitamin B 12 , folate and ferritin level were 588.80±131.58 pg/ml, 5.59±1.52 ng/ml and 89.22±42.78 ng/ml retrospectively. 2) There was no significant difference in serum levels between patients with benign diseases and normal control subjects. 3) The serum vitamin B 12 and ferritin levels in patients with liver cirrhosis were significantly higher than in normal control, and the serum folate levels in these patients were lower than in normal control subjects. 4) The serum vitamin B 12 and ferritin levels in patients with malignant tumors were significantly higher than in normal control subjects, and the serum folate levels in these patients were significantly lower than in normal control subjects. The above results suggest that the serum vitamin B 12 and ferritin may be useful as tumor markers in patients with malignant tumors.

Potential Causes of Significant Inventory Differences at Bulk Handling Facilities and the Importance of Inventory Difference Action Levels

International Nuclear Information System (INIS)

Homer, Alan; O’Hagan, Brendan

2015-01-01

Accountancy for nuclear material can be split into two categories. Firstly, where possible, accountancy should be in terms of items that can be transferred as discrete packages and their contents fixed at the time of their creation. All items must remain accounted for at all times, and a single missing item is considered significant. Secondly, where nuclear material is unconstrained, for example in a reprocessing plant where it can change form, there is an uncertainty that relates to the amount of material present in any location. Cumulatively, these uncertainties can be summed and provide a context for any estimate of material in a process. Any apparent loss or gain between what has been physically measured within a facility during its physical inventory take and what is reported within its nuclear material accounts is known as an inventory difference. The cumulative measurement uncertainties can be used to set an action level for the inventory difference so that if an inventory difference is observed outside of such action levels, the difference is classified as significant and an investigation to find the root cause(s) is required. The purpose of this paper is to explore the potential causes of significant inventory differences and to provide a framework within which an inventory difference investigation can be carried out.

2003-01-01

To study serum leptin level in chronic renal failure (CRF) hemodialysis patients and the relationship between serum leptin level and residue renal function, body composition, and indices of malnutrition, 31 end-stage CRF hemodialysis patients and 38 healthy people were enrolled. Serum leptin levels were detected by radioimmunoassay. BMI, %Fat and LBM were measured by bioelectrical impedance analysis device. Alb, Chol, Hgb, BUN, SCr and Ccr of the patients were also examined. Results showed that Serum leptin level in end-stage CRF hemodialysis patients was markedly higher than that in healthy controls (P 0.05). Conclusion: Hyperleptinemia existed in end-stage CRF hemodialysis patients and might cause the loss of LBM. The leptin level was not correlated with residue renal function, but it could reflect the fat content. However, serum leptin did not play a significant role in protein malnutrition in end-stage CRF hemodialysis patients

The aim of the present study was to investigate the relation between self-reported pain, muscular activity and postural load during cleaning tasks. Eighteen cleaners performed usual cleaning tasks in both a laboratory and a lecture room. The level of perceived pain in the neck-shoulder region......-axial accelerometer package was mounted on the low back (L5-S1) to measure postural changes during cleaning tasks. The 10th, 50th and 90th percentiles of the angular distributions were computed to characterize postures and movements. Pain tended to play a significant role on RMS of left/right trapezius and left...... erector spinae muscles (P≤0.08). Cleaners with low pain level exhibited higher muscular activity during cleaning. Pain played or tended to play a significant role on PE of left and right erector spinae muscles (P≤0.08). Pain played a significant role on the 10th, 50th and 90th percentile (P...

An Analysis of Patient Perceptions and Expectations to Dental Implants: Is There a Significant Effect on Long-Term Satisfaction Levels?

Science.gov (United States)

2017-01-01

Here we present an analysis of patient perceptions and expectations to dental implant placement and their prosthetic reconstruction, to then consider whether they have an effect on long-term satisfaction levels. A Post-Treatment Completion Questionnaire was designed to analyse whether patient satisfaction is influenced by age and/or gender; has an effect on patient-reported self-confidence levels; contributes to increased levels of oral hygiene; provides further insight into the average pain levels during and after the surgical intervention; or influences further acceptance of dental implant surgery. And then whether relationships exist between any of these factors. 182 consecutive patients completed the survey: 68 males and 114 females (age mean 64.68 years ± 11.23 SD); the average number of months since treatment completion was 37.4 (males) and 62.6 (females). There is a significant relationship between comfort rating and “how well informed” the patient was (p = 0.015). A significantly positive relationship exists between “considering dental implants in the future” and “overall experience” (p = 0.001). A significantly positive relationship exists between “overall satisfaction with appearance” and “satisfaction with comfort” (p = 0.011). A significant relationship exists between “overall satisfaction with appearance,” “satisfaction with comfort,” and “overall satisfaction with experience” (p = 0.001). The results amplify the need to transmit logical, truthful information to patients when dental implant treatment is being considered. The “fully informed” patient will have realistic expectations that lead to high degrees of satisfaction. PMID:28928771

Rhythmic gymnastics (RG) unites aesthetic, ballet-like motion, and all aspects of gymnastics. To reach elite level, girls begin at early age the intensive training. To date it is unclear if such demanding training influences the incidence and intensity of painful overuse injuries. The purpose of this study is to analyze anatomical painful regions and pain intensity in elite level rhythmic gymnasts (elRG) and compare results with an age-matched control group (CG). This prospective field study was carried out at the European Championship in RG 2013 (218 participating athletes, Vienna, Austria). Volunteering athletes were interviewed according to a preformed questionnaire. As CG secondary school pupils without any competitive sports experience were analyzed accordingly. Overall, 243 young females (144 elRG/66 % of all participants and 99 CG) were observed. ElRGs were significantly (s.) smaller, lighter, and had s. stronger pain (p < 0.001). A total of 72 % of athletes reported to have at least one painful body region compared with 52 % of CG (p < 0.001). ElRG had nearly three times more serious injuries than the CG. In all 23 % off all elRG reported to have had no access to professional medical care. ElRGs were s. more frequently (25 vs 9 %) affected at the lumbar spine and the ankle joint (17.4 vs 7 %). To our knowledge, this trial analyzes the largest cohort of elRG to date. Hence, it is clearly alluded that intensive training in RG is a significant factor causing more and stronger pain than in a CG.

Relationship Between Carbon Dioxide Levels and Reported Congestion and Headaches on the International Space Station

Congestion is commonly reported during spaceflight, and most crewmembers have reported using medications for congestion during International Space Station (ISS) missions. Although congestion has been attributed to fluid shifts during spaceflight, fluid status reaches equilibrium during the first week after launch while congestion continues to be reported throughout long duration missions. Congestion complaints have anecdotally been reported in relation to ISS CO2 levels; this evaluation was undertaken to determine whether or not an association exists. METHODS: Reported headaches, congestion symptoms, and CO2 levels were obtained for ISS expeditions 2-31, and time-weighted means and single-point maxima were determined for 24-hour (24hr) and 7-day (7d) periods prior to each weekly private medical conference. Multiple imputation addressed missing data, and logistic regression modeled the relationship between probability of reported event of congestion or headache and CO2 levels, adjusted for possible confounding covariates. The first seven days of spaceflight were not included to control for fluid shifts. Data were evaluated to determine the concentration of CO2 required to maintain the risk of congestion below 1% to allow for direct comparison with a previously published evaluation of CO2 concentrations and headache. RESULTS: This study confirmed a previously identified significant association between CO2 and headache and also found a significant association between CO2 and congestion. For each 1-mm Hg increase in CO2, the odds of a crew member reporting congestion doubled. The average 7-day CO2 would need to be maintained below 1.5 mmHg to keep the risk of congestion below 1%. The predicted probability curves of ISS headache and congestion curves appear parallel when plotted against ppCO2 levels with congestion occurring at approximately 1mmHg lower than a headache would be reported. DISCUSSION: While the cause of congestion is multifactorial, this study showed

Objective: To study the applicability of combined determination of serum VEGF and CEA levels in the diagnosis of colorectal cancer as well as the relationship between VEGF level and stage of the disease. Methods: Serum VEGF (with ELISA) and CEA (with RIA) levels serum were detected in 28 patients with colorectal cancer of various stages and 29 controls. Results: The diagnostic positive rate was 53.6% (15/28), 39.3% (11/28), 71.4% (20/28) with CEA, VEGF and combined test for colorectal cancer, respectively. The serum VEGF levels in patients with advance colorectal cancer were significantly higher than those in patients with earlier stages diseases and controls, VEGF levels were positively correlated with CEA levels (P<0.05). Conclusion: Combined detection of the levels of serum VEGF and CEA could improve significantly the diagnostic positive rate in patients with colorectal cancer. (authors)

Full Text Available Background: At low concentrations, carbon monoxide (CO can confer cyto and tissue-protective effects, such as endogenous Heme oxygenase 1 expression, which has antioxidative, anti-inflammatory, antiproliferative, and antiapoptotic effects. The level of carboxyhemoglobin in the blood is an indicator of the endogenous production of CO and inhaled CO. Aim of study: To investigate the significance of the value of carboxyhemoglobin for out-of-hospital (OH cardiopulmonary arrest (CPA. Materials and Methods: This study involved a medical chart review of cases treated from January to December 2005. The inclusion criteria included a patient who was transported to this department due to an OH CPA. The exclusion criteria included a patient who did not undergo blood gas analysis on arrival and who experienced CPA due to acute carbon monoxide intoxication. The subjects were divided into two groups based on their final outcome of either survival or non-survival. Results: There was no significant difference associated with the sex, age, frequency of witness collapse, bystander cardiopulmonary arrest, electrocardiogram at scene, cause of CPA, value of PCO 2 , HCO3 - , and methemoglobin. The frequency of OH return of spontaneous circulation and the value of pH, PO 2 , base excess, and carboxyhemoglobin in the survival group were greater than those values in the non-survival group. There were no subjects whose carboxyhemoglobin level was 0% on arrival in the survival groups. Conclusion: There appeared to be an association between higher carboxyhemoglobin levels and survival in comparison with non-survival patients.

The goals of this study were to measure the neurocognitive performance of recent users of recreational Ecstasy and investigate whether it was associated with the stress hormone cortisol. The 101 participants included 27 recent light users of Ecstasy (one to four times in the last 3 months), 23 recent heavier Ecstasy users (five or more times) and 51 non-users. Rivermead paragraph recall provided an objective measure for immediate and delayed recall. The prospective and retrospective memory questionnaire provided a subjective index of memory deficits. Cortisol levels were taken from near-scalp 3-month hair samples. Cortisol was significantly raised in recent heavy Ecstasy users compared with controls, whereas hair cortisol in light Ecstasy users was not raised. Both Ecstasy groups were significantly impaired on the Rivermead delayed word recall, and both groups reported significantly more retrospective and prospective memory problems. Stepwise regression confirmed that lifetime Ecstasy predicted the extent of these memory deficits. Recreational Ecstasy is associated with increased levels of the bio-energetic stress hormone cortisol and significant memory impairments. No significant relationship between cortisol and the cognitive deficits was observed. Ecstasy users did display evidence of a metacognitive deficit, with the strength of the correlations between objective and subjective memory performances being significantly lower in the Ecstasy users.

Significance of high level test data in piping design

International Nuclear Information System (INIS)

McLean, J.L.; Bitner, J.L.

1991-01-01

During the 1980's the piping technical community in the U.S. initiated a series of research activities aimed at reducing the conservatism inherent in nuclear piping design. One of these activities was directed at the application of the ASME Code rules to the design of piping subjected to dynamic loads. This paper surveys the test data obtained from three groups in the U.S. and none in the U.K., and correlates the findings as they relate to the failure modes of piping subjected to seismic loads. The failure modes experienced as the result of testing at dynamic loads significantly in excess of anticipated loads specified for any of the ASME Code service levels are discussed. A recommendation is presented for modifying the Code piping rules to reduce the conservatism inherent in seismic design

A community-based study was conducted to determine personal risk factors and environmental sources of lead exposure for elevated blood lead levels (≥ 10 µg/dl, EBLLs) among rural children living at the Thailand-Myanmar border in Tak Province, northwestern Thailand. Six hundred ninety-five children aged 1-14 years old were screened for BLLs. Environmental specimens for lead measurements included samples of water from the streams, taps, and household containers, house floor dust, and foods. Possible lead release from the cooking ware was determined using the leaching method with acetic acid. The overall prevalence of EBLLs was 47.1% and the geometric mean level of blood lead was 9.16 µg/dl. Personal risk factors significantly associated with EBLLs included being male, younger age, anemia, and low weight-for-age. Significant environmental risk factors were exposure to a lead-acid battery of solar energy system and use of a non-certified metal cooking pot. Some families whose children had high BLLs reported production of lead bullets from the used batteries at home. About one-third of the house dust samples taken near batteries contained lead content above the recommended value, compared with none of those taken from other areas and from the houses with no batteries. The metal pots were safe for cooking rice but might be unsafe for acidic food preparation. Both nutritional intervention and lead exposure prevention programs are essential to reduce EBLLs in this population.

Objective: To investigate the significance of changes of serum NSE and CEA levels in patients with pneumonia and malignant tumors. Methods: Serum NSE (with RIA) and CEA (with ECLIA) levels in patients with pneumonia or various kinds of malignant tumors (altogether 140 patients) and 32 controls. Results: Serum NSE and CEA levels were significantly higher in patients with lung cancer, gastric cancer, renal cancer, brain tumor and pneumonia than those in the controls (P<0.05,P <0. 05 ,P <0. 01, P<0.01, P<0.01). Positive rate of serum NSE highest in patients with pneumonia, followed successively by renal cancer, brain tumor and lung cancer. NSE levels were positively correlated with CEA levels (r=0.29, P<0.05). Conclusion: As a tumor marker, NSE has important clinical significance in the diagnoses of malignant tumor and pneumonia.

Safety of the Transport of Radioactive Materials for Civilian Use in France. Lessons learned by IRSN from analysis of significant events reported in 2014 and 2015. Mission report 2016

International Nuclear Information System (INIS)

2017-01-01

IRSN publishes its report on the safety of transport of radioactive materials for civilian use in France for the years 2014 and 2015. It is based on an overall review of the significant events that occurred during this period during transport operations in France by road, railway, inland waterway, sea and air of 980 000 parcels loaded with radioactive substances. In 2014 and 2015, respectively 139 and 122 events were reported, which is about one event reported for 7,500 packages carried. While these figures are up significantly compared to 2013 (93 reported events, or 1 in 10,000 packages carried), IRSN believes that this trend should not however be interpreted as a deterioration of the safety level of the transport of radioactive materials. Indeed, it is largely explained by better detection of events relevant to safety by the actors concerned and therefore their declaration to the authorities. None of these events had significant radiological consequences for the workers, the population or the environment. As part of progress made, IRSN notes a sharp decrease, in 2015, in the number of damage of packages intended for medical activities during their handling in airport areas. This decrease is linked to awareness actions conducted for airlines companies and staff involved in the handling of packages. Finally, three themes must be the subject of particular vigilance of the actors concerned and of corrective actions: - Compliance with the requirements for the transport of gamma radiography devices, in particular those associated with the locking of the source; events related to the transport of gamma radiography devices appeared as remarkable events over the period (3 level 1 events and 1 level 2 events); - The tie-down of packages on their means of transport, given the risks of fall of the package during transport, as well as tie-down of the objects in their transport container; - The operations of filling and closing of drums containing uranium ore in order to

2007-01-01

Objective: To investigate the changes of plasma motilin, plasma somatostatin and serum gastrin levels after beginning oral feeding in 68 small for gestational age neonates (pre-term 36, full-term 32). Methods: Blood levels of somatostatin (SS), motilin and gastrin were determined with RIA before beginning of oral feeding and on 7 th day after birth in 68 small for gestational age neonates and 30 controls. Results: The blood levels of motilin and gastrin before feeding and on 7 th day in the small for gestational age neonates were significantly lower than those in the controls, while the SS levels were significantly higher. The serum levels of the hormones rose gradually after birth and on 7 th day were all significantly higher than those before feeding respectively (P th day levels were positively correlated with gestational age, original levels before feeding and early feeding. For gastrin, the levels were also positively correlated with the amount of feeding. In this study, early oral feeding was practiced in all the neonates without any adverse effect. Conclusion: Although the blood levels of gastro-intestinal hormones were lower in small for gestational age newborns, early oral feeding was practiced in all the neonates with no adverse effect observed and more rapid elevation of the hormone levels. Therefore, early oral feeding should be encouraged. (authors)

Objective: To study the clinical significance of determination of serum leptin, AsAb, and EmAb levels in infertile women. Methods: Serum leptin (with RIA) and AsAb, EmAb (with ELISA) levels were detected in 32 infertile women and 35 controls. Results: Serum leptin levels in infertile women were significantly lower than those in controls (P<0.01). Serum AsAb and EmAb were both positive in 25 of the 32 infertile women (78.1%) and EmAb (one of two Abs) was positive in the rest 7 women (21.9%). These positive rates were also significantly higher than the respective ones in the controls (both P<0.01). Conclusion: Lower serum leptin level with highly positive AsAb and EmAb might be the chief cause of infertility in women. (authors)

To investigate the association between self-reported sleep duration and serum vitamin D level in elderly Korean adults. Cross-sectional data analysis. Korean National Health and Nutrition Examination Survey 2010. Noninstitutionalized adults aged 60 to 80 (N = 1,614). The confounding variables were serum 25-hydroxy vitamin D level, age, sex, body mass index, smoking history, alcohol consumption, and self-reported daily sun exposure and sleep duration. Self-reported daily sleep duration was divided into four groups: Q1 (≤4 hours), Q2 (5-6 hours), Q3 (7-8 hours), and Q4 (≥9 hours). Mean serum vitamin D levels of subjects in the Q1, Q2, Q3, and Q4 groups were 44.18, 48.08, 48.83, and 51.78 nmol/L, respectively. On multivariate linear regression analysis, subjects in the Q2 (B = 3.80, 95% confidence interval (CI) = 0.42-7.19), Q3 (B = 4.89, 95% CI = 1.54-8.24), and Q4 (B = 5.18, 95% CI = 0.78-9.58) groups had significantly higher serum vitamin D levels than subjects in the Q1 group. Serum vitamin D level is positively associated with self-reported daily sleep duration in elderly Korean individuals. These results suggest that inadequate sleep duration may be associated with lower vitamin D levels in elderly adults. © 2014, Copyright the Authors Journal compilation © 2014, The American Geriatrics Society.

Methods: Serum TPOAb (with RIA) and TRAb (with RRA) levels were determined in 27 patients with Graves' disease, before treatment 10 patients with Graves' disease clinically cured and 35 controls. Results: The serum levels and positive rates of TPOAb and TRAb in patients with Graves' disease before treatment were significantly higher than those in the patients with Graves' disease clinically cured and controls (P<0.01). Conclusion: TPOAb and TRAb were involved in the pathogenesis of Graves' dis- ease and could be used as diagnostic and treatment indicators. (authors)

A Note on Comparing the Power of Test Statistics at Low Significance Levels.

Science.gov (United States)

Morris, Nathan; Elston, Robert

2011-01-01

It is an obvious fact that the power of a test statistic is dependent upon the significance (alpha) level at which the test is performed. It is perhaps a less obvious fact that the relative performance of two statistics in terms of power is also a function of the alpha level. Through numerous personal discussions, we have noted that even some competent statisticians have the mistaken intuition that relative power comparisons at traditional levels such as α = 0.05 will be roughly similar to relative power comparisons at very low levels, such as the level α = 5 × 10 -8 , which is commonly used in genome-wide association studies. In this brief note, we demonstrate that this notion is in fact quite wrong, especially with respect to comparing tests with differing degrees of freedom. In fact, at very low alpha levels the cost of additional degrees of freedom is often comparatively low. Thus we recommend that statisticians exercise caution when interpreting the results of power comparison studies which use alpha levels that will not be used in practice.

Longcore, J.R.; Locke, L.N.; Bagley, George E.; Andrews, R.

1974-01-01

Tissues of adult, lead-dosed mallards that either died or were sacrificed were analyzed for lead. Lead levels in brains, tibiae, and breast muscle of ducks that died and in tibiae of ducks that were sacrificed increased significantly from dosage until death. Lead in the heart, lung, and blood from sacrificed ducks decreased significantly from dosage until death. Lead concentrations in tissues from ducks in the two groups were not significantly different except for the liver, kidney, and lung. Average lead levels in the livers and kidneys of ducks that died were significantly higher than those in ducks that were sacrificed. The mean concentration of lead in the lungs of the ducks sacrificed was significantly higher than the mean level in the lungs of ducks that died. Measurements of the lead concentrations in this study, when compared with lead levels reported in the literature for avian and non-avian species, showed that arbitrary diagnostic levels indicating lead poisoning could be set. In mallard ducks, lead levels exceeding 3 ppm in the brain, 6 to 20 ppm in the kidney or liver, or 10 ppm in clotted blood from the heart indicated acute exposure to lead.

Objective: To investigate the clinical usefulness of determination of serum SA, CEA and CRP levels in patients with colorectal cancer. Methods: Serum SA (with colorimetry), CEA (with CLIA) and CRP (with ILIA) levels were measured in 120 patients with colo-rectal cancer. Results: (1) Serum SA, CEA and CRP levels increased significantly as the disease stage advanced from Duke A through Duke D. (2) As the malignancy of the growth advanced from well-differentiated to anaplastic, the serum SA and CRP levels increased significantly while the reverse was true for serum CEA levels. (3) In 68 post-operative patients followed 1-5 years, the serum levels of SA, CEA and CRP were significantly higher in the patients with recurrence (n=29) than those in patients without recurrence (n=39) (P<0.01). Conclusion: Serum SA CEA and CRP levels were closely related to the disease process in patients with colo-rectal cancer. (authors)

Objective: To explore the relationship between the serum leptin, insulin levels and development of polycystic ovary syndrome (PCOS). Methods: Serum leptin and insulin levels (with RIA) were determined in 34 patients with PCOS and 30 controls. Results: The serum leptin and insulin levels in the 34 PCOS patients were significantly higher than those in controls (P<0. 01), and those in obese patients (n=22) were significantly higher than those in non-obese ones (n=12) too(P<0.01). Conclusion: Changes of serum leptin and insulin levels were closely related to the development of PCOS and leptin might be used as a diagnostic indicator for PCOS. (authors)

The preparation of reports of a significant event at a uranium processing or uranium handling facility

International Nuclear Information System (INIS)

1988-08-01

Licenses to operate uranium processing or uranium handling facilities require that certain events be reported to the Atomic Energy Control Board (AECB) and to other regulatory authorities. Reports of a significant event describe unusual events which had or could have had a significant impact on the safety of facility operations, the worker, the public or on the environment. The purpose of this guide is to suggest an acceptable method of reporting a significant event to the AECB and to describe the information that should be included. The reports of a significant event are made available to the public in accordance with the provisions of the Access to Information Act and the AECB's policy on public access to licensing information

2006-01-01

Objective: To determine the insulin (INS), glucagon (GLUC) and cortisol (COR) levels in maternal and umbilical cord blood for appropriate gestational age (AGA) neonates and to explore the correlation among the body weight of AGA neonates and body mass index (BMI) of pregnant woman, serum INS, GLUC, COR levels of maternal as well as umbilical cord blood. Methods: Neonates fell into lower-than-normal body weight group ( group A n=9) and higher-than-normal body weight group (group B n =17); serum INS, GLUC and COR levels were measured with radioimmunoassay in 26 pairs of mothers and neonates with uneventful delivery. Results: The body weight of neonate was positively correlated with the BMI of pregnant women, the BMI of pregnant women in group B were significantly higher than those in group A (P<0.05). The maternal serum GLUC and COR levels were significantly higher than those in cord blood (P<0.05, P<0.01). Cord blood COR contents in group B were significantly higher than those in group A (P<0.01), the reverse was true for GLUC (P<0.05). Conclusion: Fetal growth is closely related to the BMI of pregnant women and serum INS, GLUC and COR levels indicating that maternal nutritional condition would directly affect the birth weight of the neonates.

'The goal of this report is to establish a protocol for assessing risks to non-human populations exposed to environmental stresses typically found on many DOE sites. The authors think that they can achieve this by using novel biological dosimeters in controlled, manipulative dose/effects experiments, and by coupling changes in metabolic rates and energy allocation patterns to meaningful population response variables (such as age-specific survivorship, reproductive output, age at maturity and longevity). This research is needed to determine the relevancy of sublethal cellular damage to the performance of individuals and populations exposed to chronic, low-level radiation, and radiation with concomitant exposure to chemicals. They believe that a scientifically defensible endpoint for measuring ecological risks can only be determined once its understood the extent to which molecular damage from contaminant exposure is detrimental at the individual and population levels of biological organization. The experimental facility will allow them to develop a credible assessment tool for appraising ecological risks, and to evaluate the effects of radionuclide/chemical synergisms on non-human species. This report summarizes work completed midway of a 3-year project that began in November 1996. Emphasis to date has centered on three areas: (1) developing a molecular probe to measure stable chromosomal aberrations known as reciprocal translocations, (2) constructing an irradiation facility where the statistical power inherent in replicated mesocosms can be used to address the response of non-human organisms to exposures from low levels of radiation and metal contaminants, and (3) quantifying responses of organisms living in contaminated mesocosms and field sites.'

Proton pump inhibitors (PPI) are among the most widely prescribed drugs to treat gastric acid-related disorders. PPI-induced hypomagnesaemia, a defect in intestinal absorption of Mg(2+) , can be a severe side effect of chronic PPI use. To restore serum Mg(2+) concentrations in PPI-induced hypomagnesaemia patients by dietary supplementation with inulin fibres. Eleven patients with PPI-induced hypomagnesaemia and 10 controls were treated with inulin (20 g/day). Each trial consisted of two cycles of 14-day inulin treatment followed by a washout period of 14 days. Patients continued to use their PPI. Serum Mg(2+) levels served as the primary endpoint. Inulin significantly enhanced serum Mg(2+) levels from 0.60 to 0.68 mmol/L in PPI-induced hypomagnesaemia patients, and from 0.84 to 0.93 mmol/L in controls. As a consequence 24 h urinary Mg(2+) excretion was significantly increased in patients with PPI-induced hypomagnesaemia (0.3-2.2 mmol/day). Symptoms related to hypomagnesaemia, including muscle cramps and paraesthesia, were reduced during intervention with inulin. Inulin increases serum Mg(2+) concentrations under PPI maintenance in patients with PPI-induced hypomagnesaemia. © 2016 John Wiley & Sons Ltd.

Krill oil significantly decreases 2-arachidonoylglycerol plasma levels in obese subjects

Directory of Open Access Journals (Sweden)

Giordano Elena

2011-01-01

Full Text Available Abstract We have previously shown that krill oil (KO, more efficiently than fish oil, was able to downregulate the endocannabinoid system in different tissues of obese zucker rats. We therefore aimed at investigating whether an intake of 2 g/d of either KO or menhaden oil (MO, which provides 309 mg/d of EPA/DHA 2:1 and 390 mg/d of EPA/DHA 1:1 respectively, or olive oil (OO for four weeks, is able to modify plasma endocannabinoids in overweight and obese subjects. The results confirmed data in the literature describing increased levels of endocannabinoids in overweight and obese with respect to normo-weight subjects. KO, but not MO or OO, was able to significantly decrease 2-arachidonoylglycerol (2-AG, although only in obese subjects. In addition, the decrease of 2-AG was correlated to the plasma n-6/n-3 phospholipid long chain polyunsaturated fatty acid (LCPUFA ratio. These data show for the first time in humans that relatively low doses of LCPUFA n-3 as KO can significantly decrease plasma 2-AG levels in obese subjects in relation to decrease of plasma phospholipid n-6/n-3 LCPUFA ratio. This effect is not linked to changes of metabolic syndrome parameters but is most likely due to a decrease of 2-AG biosynthesis caused by the replacement of 2-AG ultimate precursor, arachidonic acid, with n-3 PUFAs, as previously described in obese Zucker rats.

Low-level and mixed waste incinerator survey report

International Nuclear Information System (INIS)

Garcia, E.C.

1988-10-01

The Low-Level and Mixed Waste Survey Task was initiated to investigate and document current and planned incinerator facilities in the Department of Energy Defense Programs (DOE-DP) system. A survey was mailed to the DOE field offices requesting information regarding existing or planned incinerator facilities located under their jurisdiction. The information requested included type, capacities, uses, costs, and mechanical description of the incinerators. The results of this survey are documented in this report. Nine sites responded to the survey, with eight sites listing nine incineration units in several stages of operations. The Idaho National Engineering Laboratory listed two operational facilities. There are four incinerators that are planned for start-up in 1991. Of the existing incinerators, three are used mostly for low-level wastes, while the planned units will be used for low-level, mixed, and hazardous wastes. This report documents the current state of the incineration facilities in the DOE-DP system and provides a preliminary strategy for management of low-level wastes and a basis for implementing this strategy. 5 refs., 4 figs., 14 tabs

Serum alkaline phosphatase (SALP) is commonly elevated in osteosarcoma patients. A number of studies have investigated the prognostic role of SALP level in patients with osteosarcoma but yielded inconsistent results. Systematic computerized searches were performed in PubMed, Embase, and Web of Science databases for relevant original articles. The pooled hazard ratios (HRs) and relative risks (RRs) with corresponding confidence intervals (CIs) were calculated to assess the prognostic value of SALP level. Finally, 21 studies comprising 3228 patients were included. Overall, the pooled HRs of SALP suggested that elevated level had an unfavorable impact on osteosarcoma patients' overall survival (OS) (HR = 1.82; 95% CI: 1.61-2.06; p SALP indicated that elevated level was associated with presence of metastasis at diagnosis (RR = 5.55; 95% CI: 1.61-9.49; p = 0.006). No significantly different results were obtained after stratified by variables of age range, cancer stage, sample size, and geographic region. This meta-analysis demonstrated that high SALP level is significantly associated with poor OS or EFS rate and presence of metastasis at diagnosis. SALP level is a convenient and effective biomarker of prognosis for osteosarcoma.

Objective: To explore the changes and clinical significance of serum insulinlike growth factor II (IGF II) levels in coronary heart disease (CHD) patients. Methods: The serum IGF II levels were determined by radioimmunoassay in 68 patients with coronary heart disease (CHD) and 30 controls with only mild non-cardiac diseases. Results: Compared with the controls, the serum IGF II level in CHD patients were increased significantly (0.66 ± 0.13 μg/L vs 0.51 ± 0.11 μg/L; t = 5.506, p 0.05). Level in patients dies in hospital (n = 9) were much higher than those in patients recovered (n = 59) (t = 2.402, p < 0.05). Conclusion: Serum IGF II levels seems to be related to the seriousness of CHD; the actual mechanism remains to be defined

Objective: To investigate the correlationship between the plasma homocysteine (Hcy) levels and development of hepatic cirrhosis as well as the diagnostic value of plasma Hcy determination. Method: Plasma Hcy levels were measured with ELISA in: (1) 64 patients with post-hepatitis cirrhosis (2) 42 patients with various types of hepatitis but no cirrhosis and (3) 60 controls. Results: The plasma levels of Hcy in patients with cirrhosis were significantly higher than those in the other two groups (P<0.01). The plasma Hcy levels in cirrhotic patients were well correlated with the levels of other hepatic fibrosis markers such as hyaluronic acid and laminin (r=0.87 and r=0.88 respectively, P<0.01), but were not correlated with cholesterol, triglyceride and HDL levels. Conclusion: Plasma Hcy levels was markedly elevated in cirrhotic patients and might be taken as a diagnostic marker. (authors)

2012-01-01

Full Text Available Limited research suggests yoga may be a viable gentle physical activity option with a variety of health-related quality of life, psychosocial and symptom management benefits. The purpose of this review was to determine the clinical significance of patient-reported outcomes from yoga interventions conducted with cancer survivors. A total of 25 published yoga intervention studies for cancer survivors from 2004–2011 had patient-reported outcomes, including quality of life, psychosocial or symptom measures. Thirteen of these studies met the necessary criteria to assess clinical significance. Clinical significance for each of the outcomes of interest was examined based on 1 standard error of the measurement, 0.5 standard deviation, and relative comparative effect sizes and their respective confidence intervals. This review describes in detail these patient-reported outcomes, how they were obtained, their relative clinical significance and implications for both clinical and research settings. Overall, clinically significant changes in patient-reported outcomes suggest that yoga interventions hold promise for improving cancer survivors' well-being. This research overview provides new directions for examining how clinical significance can provide a unique context for describing changes in patient-reported outcomes from yoga interventions. Researchers are encouraged to employ indices of clinical significance in the interpretation and discussion of results from yoga studies.

Confidence levels, clinical significance curves, and risk-benefit contours are tools improving analysis of clinical studies and minimizing misinterpretation of published results, however no software has been available for their calculation. The objective was to develop software to help clinicians utilize these tools. Excel 2000 spreadsheets were designed using only built-in functions, without macros. The workbook was protected and encrypted so that users can modify only input cells. The workbook has 4 spreadsheets for use in studies comparing two patient groups. Sheet 1 comprises instructions and graphic examples for use. Sheet 2 allows the user to input the main study results (e.g. survival rates) into a 2-by-2 table. Confidence intervals (95%), p-value and the confidence level for Treatment A being better than Treatment B are automatically generated. An additional input cell allows the user to determine the confidence associated with a specified level of benefit. For example if the user wishes to know the confidence that Treatment A is at least 10% better than B, 10% is entered. Sheet 2 automatically displays clinical significance curves, graphically illustrating confidence levels for all possible benefits of one treatment over the other. Sheet 3 allows input of toxicity data, and calculates the confidence that one treatment is more toxic than the other. It also determines the confidence that the relative toxicity of the most effective arm does not exceed user-defined tolerability. Sheet 4 automatically calculates risk-benefit contours, displaying the confidence associated with a specified scenario of minimum benefit and maximum risk of one treatment arm over the other. The spreadsheet is freely downloadable at www.ontumor.com/professional/statistics.htm A simple, self-explanatory, freely available spreadsheet calculator was developed using Excel 2000. The incorporated decision-making tools can be used for data analysis and improve the reporting of results of any

Background Carcinoembryonic antigen (CEA) is commonly used as a serum tumor marker in clinical practice; however, its prognostic value for gastric cancer patients remains uncertain. This meta-analysis was performed to assess the prognostic value of CEA and investigate CEA as a tumor marker. Methods PubMed, EMBASE and other databases were searched for potentially eligible studies. Forty-one studies reporting the prognostic effect of pretreatment serum CEA expression in gastric cancer patients were selected. Data on 14651 eligible patients were retrieved for the meta-analysis. Based on the data extracted from the available literature, the hazard ratio (HR) and 95% confidence interval (CI) for an adverse prognosis were estimated for gastric cancer patients with elevated pretreatment serum levels of CEA (CEA+) relative to patients with normal pretreatment CEA levels (CEA-). Results The CEA+ patients had a significantly poorer prognosis than the CEA- patients in terms of overall survival (OS: HR 1.716, 95% CI 1.594 - 1.848, P 0.05). In the pooled analyses of multivariate-adjusted HRs, the results suggested that pretreatment serum CEA may be an independent prognostic factor in gastric cancer (OS: HR 1.681, 95% CI 1.425 - 1.982; DSS: HR 1.900, 95% CI 1.441 - 2.505; DFS: HR 2.579, 95% CI 1.935 - 3.436). Conclusion/Significance The meta-analysis based on the available literature supported the association of elevated pretreatment serum CEA levels with a poor prognosis for gastric cancer and a nearly doubled risk of mortality in gastric cancer patients. CEA may be an independent prognostic factor for gastric cancer patients and may aid in determining appropriate treatment which may preferentially benefit the CEA+ patients. PMID:25879931

Published P-values provide a window into the global enterprise of medical research. The aim of this study was to use the distribution of published P-values to estimate the relative frequencies of null and alternative hypotheses and to seek irregularities suggestive of publication bias. This cross-sectional study included P-values published in 120 medical research articles in 2016 (30 each from the BMJ, JAMA, Lancet, and New England Journal of Medicine). The observed distribution of P-values was compared with expected distributions under the null hypothesis (i.e., uniform between 0 and 1) and the alternative hypothesis (strictly decreasing from 0 to 1). P-values were categorized according to conventional levels of statistical significance and in one-percent intervals. Among 4,158 recorded P-values, 26.1% were highly significant (P values values equal to 1, and (3) about twice as many P-values less than 0.05 compared with those more than 0.05. The latter finding was seen in both randomized trials and observational studies, and in most types of analyses, excepting heterogeneity tests and interaction tests. Under plausible assumptions, we estimate that about half of the tested hypotheses were null and the other half were alternative. This analysis suggests that statistical tests published in medical journals are not a random sample of null and alternative hypotheses but that selective reporting is prevalent. In particular, significant results are about twice as likely to be reported as nonsignificant results. Copyright © 2017 Elsevier Inc. All rights reserved.

The aim of this study was to assess the effect of parent report gross motor function level of cerebral palsy (CP) children on the parent report quality of life of CP children. Sampling of this cross-sectional study was done in occupational therapy clinics and CP children's schools in 2016 in Zanjan, Iran. Samples size was 60 CP children aged 6-12 yr and for sampling method, a non-probability convenience was used. For assessing the quality of life of CP children the cerebral palsy quality of life (CP QOL) questionnaire and for assessing the level of gross motor function of CP children the Gross Motor Function Classification System Family Report Questionnaire (GMFCSFRQ) were used. The average age of children (22 males and 30 females) was 8.92 yr old (minimum 6 yr and maximum 12 yr). The relationship between the level of gross motor function and participation and physical health was direct and significant (r=0.65). The relationship between functioning, access to services and family health with the level of gross motor function was direct but was not significant ( P >0.05) and the relationship between pain and impact of disability and emotional well-being with the level of gross motor function was significant ( P quality of life of children with cerebral palsy. It means that the level of gross motor function cannot be used as a predictor of quality of life for children with cerebral palsy alone.

To evaluate the significance of serum beta{sub 2}-microglobulin in patients with various liver diseases, serum {sub 2} m levels were measured in 44 cases of normal controls, 32 cases of asymptomatic HBsAg carriers and 134 patients with various liver diseases, by radioimmunoassay using Phadebas Beta{sub 2}-micro test kits. The following results were obtained: I) The mean level of serum beta{sub 2} m was 1 39+-0.25 mg/l(Mean+-S.D.) in normal controls (1.39+-0.23 mg/l in 24 males, 1.38+-0,27 mg/l in 20 females). 2) The serum levels of beta{sub 2} in patients with various liver diseases and asymptomatic HBsAg carriers were as follows; 1.40+-0.27 mg/l in asymptomatic HBsAg carriers, 2.42+-0.377 mg/l in 45 patients with acute viral hepatitis, 2.10+-0.26 mg/l in 46 patients with chronic persistent hepatitis, 2.60+-0.34 mg/l in 23 patients with chronic active hepatitis, and 2.60+-0.49 mg/l in 20 patients with liver cirrhosis. Serum beta{sub 2}m levels of each disease group were significantly higher than that of normal controls(p<0.001). 3) There was significant correlation between the levels of serum beta{sub 2}m and the degrees of lymphocytic infiltration in patients with chronic active hepatitis(p<0.001). 4) Significant correlations were observed between the levels of serum beta{sub 2}-microglobulin and serum alanine aminotransferase(r=0.68, p<0.05) and bilirubin(r=0.63, p<0.05) in 15 patients with acute viral hepatitis. In conclusion, the serum beta{sub 2}-microglobulin levels were increased in patients with various liver diseases, and it may serve as a new index of liver disease activity.

2007-12-01

Full Text Available It is recognized that much of the dietary data on adolescents and athletes is prone to reporting error, mostly through under-reporting. Nevertheless, in the majority of studies assessing the nutritional intake of young soccer players under-reporting has not been taken into consideration. The purpose of this study was to assess the dietary intake of a sample of young male Italian high-level soccer players on two time points to evaluate the degree of under- reporting. Seventy-five male high level soccer players (age range: 15-17 years completed 4-day food records on two separate occasions (T0; T1, 3 months after T0. Under-reporting was assessed by the ratio of reported estimated energy intake (EEI to estimated energy expenditure (EEE. Forty- three subjects, whose food records were judged accurate enough both at T0 and T1, were included in the data analysis (inclusion rate 57.3%. No significant weight changes were documented between T0 and T1 and in the two weeks preceding both T0 and T1. Reported mean daily energy intake was significantly lower than mean estimated daily energy expenditure both at T0 and T1 (p < 0.001. The average EEI/EEE ratio was 0.75 + 0.2 both at T0 and T1. It was < 80% in 27 subjects (62.8% at T0 and in 23 (53.4% at T1; it reached 50% in 4 subjects both at T0 and T1. The degree of under- reporting of the young soccer players was in line with the available data on this age group. This study emphasizes that under-reporting is a critical issue in the evaluation of young athletes dietary intake, which should be considered in the interpretation of data, particularly when energy inadequacies are reported. Further studies with uniformed methods are needed, in order to reduce the degree of under-reporting, obtain reliable data on the dietary intake of young soccer players and evaluate the efficacy of targeted nutrition education programs

International Nuclear Information System (INIS)

1998-02-01

In the Report accompanying the Fiscal Year 1997 Senate Energy and Water Development Appropriations Bill, the Senate Appropriations Committee directed the Department of Energy (DOE) to prepare a study of the costs of operating a low-level radioactive waste (LLW) disposal facility such as the one at Barnwell, South Carolina, and to determine whether LLW generators are paying equitable disposal fees. The disposal costs of four facilities are reviewed in this report, two operating facilities and two planned facilities. The operating facilities are located at Barnwell, South Carolina, and Richland, Washington. They are operated by Chem-Nuclear, LLC, (Chem-Nuclear), and US Ecology, Inc., (US Ecology), respectively. The planned facilities are expected to be built at Ward Valley, California, and Sierra Blanca, Texas. They will be operated by US Ecology and the State of Texas, respectively. This report found that disposal fees vary significantly among facilities for a variety of reasons. However, the information suggests that at each disposal facility, LLW generators pay equitable disposal fees

Objective: To explore the clinical significance changes of serum TNF-α, VEGF and TSGF levels after treatment in patients with aplastic Anemia. Methods: Serum TNF-α(with RIA), VEGF(with ELISA) and TSGF(with biochemistry) levels were determined in 33 patients with aplastic anemia both before and after treatment and 35 controls. Results: Before treatment, the serum TNF-α, TSGF levels were significantly higher in the patients than those in controls (P<0.01), but serum VEGF levels were significantly lower in the patients (P<0.01). Serum TNF-α, TSGF levels were negatively correlated with levels of VEGF(r=-0.5192, -0.6018, P<0.01). After a course of treatment, the serum TNF-α, VEGF and TSGF levels, though corrected markedly, remained significantly different from those in controls (P<0.05). Conclusion: Determination of serum TNF-α, VEGF and TSGF levels after treatment might be of prognostic importance in patients with aplastic anemia. (authors)

Sea level report

International Nuclear Information System (INIS)

Schwartz, M.L.

1979-01-01

Study of Cenozoic Era sea levels shows a continual lowering of sea level through the Tertiary Period. This overall drop in sea level accompanied the Pleistocene Epoch glacio-eustatic fluctuations. The considerable change of Pleistocene Epoch sea level is most directly attributable to the glacio-eustatic factor, with a time span of 10 5 years and an amplitude or range of approximately 200 m. The lowering of sea level since the end of the Cretaceous Period is attributed to subsidence and mid-ocean ridges. The maximum rate for sea level change is 4 cm/y. At present, mean sea level is rising at about 3 to 4 mm/y. Glacio-eustacy and tectono-eustacy are the parameters for predicting sea level changes in the next 1 my. Glacio-eustatic sea level changes may be projected on the basis of the Milankovitch Theory. Predictions about tectono-eustatic sea level changes, however, involve predictions about future tectonic activity and are therefore somewhat difficult to make. Coastal erosion and sedimentation are affected by changes in sea level. Erosion rates for soft sediments may be as much as 50 m/y. The maximum sedimentation accumulation rate is 20 m/100 y

Full Text Available Background. Serum alkaline phosphatase (SALP is commonly elevated in osteosarcoma patients. A number of studies have investigated the prognostic role of SALP level in patients with osteosarcoma but yielded inconsistent results. Method. Systematic computerized searches were performed in PubMed, Embase, and Web of Science databases for relevant original articles. The pooled hazard ratios (HRs and relative risks (RRs with corresponding confidence intervals (CIs were calculated to assess the prognostic value of SALP level. Results. Finally, 21 studies comprising 3228 patients were included. Overall, the pooled HRs of SALP suggested that elevated level had an unfavorable impact on osteosarcoma patients’ overall survival (OS (HR = 1.82; 95% CI: 1.61–2.06; p<0.001 and event-free survival (EFS (HR = 1.97; 95% CI: 1.61–2.42; p<0.001. Combined RRs of SALP indicated that elevated level was associated with presence of metastasis at diagnosis (RR = 5.55; 95% CI: 1.61–9.49; p=0.006. No significantly different results were obtained after stratified by variables of age range, cancer stage, sample size, and geographic region. Conclusion. This meta-analysis demonstrated that high SALP level is significantly associated with poor OS or EFS rate and presence of metastasis at diagnosis. SALP level is a convenient and effective biomarker of prognosis for osteosarcoma.

At the Hanford Site in Richland, Washington, the path to site cleanup involves vitrification of the majority of the wastes that currently reside in large underground tanks. A Joule-heated glass melter is the equipment of choice for vitrifying the high-level fraction of these wastes. Even though this technology has general national and international acceptance, opportunities may exist to improve or change the technology to reduce the enormous cost of accomplishing the mission of site cleanup. Consequently, the U.S. Department of Energy requested the staff of the Tanks Focus Area to review immobilization technologies, waste forms, and modifications to requirements for solidification of the high-level waste fraction at Hanford to determine what aspects could affect cost reductions with reasonable long-term risk. The results of this study are summarized in this report.

Level best : drilling seasonal load leveling business case : final report

International Nuclear Information System (INIS)

2005-10-01

Drilling and seismic costs in Western Canada are as much as 35 per cent higher during winter months. Favourable commodity pricing has prompted aggressive expansion of drilling programs in the Western Canada Sedimentary Basin (WCSB), and capacity is becoming a significant issue. Many operators are turning to load leveling in order to secure rigs and crew availability. However, many operators still adhere to the traditional view that drilling of oil and gas wells is best accomplished during the winter. The purpose of the project discussed in this paper was to develop and present a business case for greater seasonal load leveling in the WCSB and spreading it more evenly throughout the year. Using calendar year quarters, publicly available data for a 5 year period from 2000-2004 for drilling activity, safety, weather, and environmental restrictions were examined. A list of candidate fields with high levels of activity and a good representation of well depths was selected. Well cost and rig data from 14 different companies was used. A variety of industry participants, drilling contractors, load leveling technology suppliers and provincial agencies were consulted to supplement well cost analyses. The financial impacts of load leveling were examined. Benefits included lower well costs; advanced production; avoided rig construction; reduced incident rates; and reduced turnover. While the focus of the business case for load leveling was based on hard cost data, many indirect benefits were identified, including First Nations sustainability and greater job security and comfort for workers. Various policies and incentives that encouraged load leveling in British Columbia and Alberta were reviewed. 57 figs

Objective: To explore the value of determination of plasma β-AP levels in the diagnosis and monitoring of Alzheimer's disease (AD). Methods: Plasma β-AP levels were weasured with RIA in 43 patients with AD and 58 controls, as well as in 8 AD patients after a course of cerebrolysin treatment. Results: The plasma β-AP levels in the AD patients were significance higher those in controls (P<0.01). The plasma β-AP levels were especially higher in the severe eases, however, the plasma β-AP levels in some late AD patients dropped again, even lower than those in the controls. The plasma β-AP levels in the 8 AD patients decreased significantly after treatment with cerebrolysin. Conclusion: The plasma β-AP is a biochemical maker of AD. Dynamic examnation of plasma β-AP levels is valuable in assessing the progression and prognosis of the disease. (authors)

Laparoscopic single anastomosis gastric bypass (SAGB) is increasingly performed for morbidly obese patients. This pilot study aims primarily at evaluating the incidence of bile gastritis after SAGB. The occurrence of reflux oesophagitis and reflux symptoms were also assessed. This study included 20 patients having no reflux symptoms. All patients underwent a SAGB as a primary bariatric procedure by a single surgeon. Patients included consented to have an upper GI endoscopy done at 6 months postoperatively. Gastric aspirate was sent for bilirubin level assessment. Gastric and esophageal biopsies were submitted for histopathology and campylobacter-like organism (CLO) test. In our study, the rate of bile gastritis was 30%. In 18 patients, the level of bilirubin in gastric aspirate seems to be related to the degree of mucosal inflammation. The remaining two patients had microscopic moderate to severe gastritis with normal aspirate bilirubin level. Two patients with bilirubin level in aspirate more than 20 mg/dl had severe oesophagitis, gastritis with erosions, and metaplasia. Relationship between bilirubin level and histopathological findings of gastric biopsy examination was statistically significant with a P value of 0.001. The incidence of bile gastritis in this cohort is higher than reported in the literature, and this may be worrying. The correlation between endoscopic findings and patients' symptoms is poor. Bilirubin level and pH in aspirate might be useful tools to confirm alkaline reflux. Its level might help to choose candidates for revision surgery after SAGB. This needs further validation with larger sample size.

Objective: To investigate the serum leptin concentration in polycystic ovary syndrome (PCOS) with hyperandrogenemia (HA) and its relationship with testosterone (T) level and body mass index (BMI). Methods: Serum leptin levels were measured by radioimmunoassay in 53 patients with PCOS, in which 36 cases were of the in non-obesity group and 17 cases in obese group. 30 non-obese cases and 20 obese cases without PCOS served as controls. Results: The levels of leptin in PCOS with HA in obese and non-obese group were significantly higher than those in control group (all p < 0.01). There was a positive correlation between serum leptin levels and testosterone levels in both groups (r = 0.51, p < 0.01 and r = 0.58, p < 0.01). No correlation existed between serum leptin levels and body mass index (BMI) in PCOS patients of non-obese group but there was positive correlation in obesity group (r = 0.56, p < 0.01). Conclusion: High serum leptin levels is one of the characteristic in PCOS patients. The HA in PCOS patients is related to serum leptin levels and heavyweight or obese patients have the phenomenon of leptin resistance

This study measured sound levels in a 2008 built French neonatal intensive care unit (NICU) and compared them to the 2007 American Academy of Pediatrics (AAP) recommendations. The ultimate aim was to identify factors that could influence noise levels. The study measured sound in 17 single or double rooms in the NICU. Two dosimeters were installed in each room, one inside and one outside the incubators, and these conducted measurements over a 24-hour period. The noise metrics measured were the equivalent continuous sound level (L eq ), the maximum noise level (L max ) and the noise level exceeded for 10% of the measurement period (L 10 ). The mean L eq , L 10 and L max were 60.4, 62.1 and 89.1 decibels (dBA), which exceeded the recommended levels of 45, 50 and 65 dBA (p care was correlated to an increased noise level, except for a postconceptional age below 32 weeks. The sound levels significantly exceeded the AAP recommendations, particularly inside incubators. A multipronged strategy is required to improve the sound environment and protect the neonates' sensory development. ©2017 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

Additionally, we evaluated relationship of HER2/neu levels with tumor stage, grade, recurrence and progression. Materials and Methods: Fourty-four patients with primary non-muscle invasive bladder tumors (Group 2 and 40 healthy control group (Group 1 were included the study. Blood and urinary samples were collected from all patients and HER2/neu levels were measured by ELISA method. Blood and urinary HER2/neu levels and additionally, ratio of urinary HER2/neu levels to urinary creatinine levels were recorded. Demographic data and tumor characteristics were recorded. Results: Mean serum HER2/neu levels were similar between two groups and statistically significant difference wasn't observed. Urinary HER2/neu levels were significantly higher in group 2 than group 1. Ratio of urinary HER2/neu to urinary creatinine was significantly higher in group 2 than group 1, (p=0,021. Serum and urinary HER2/ neu levels were not associated with tumor stage, grade, recurrence and progression while ratio of urinary HER2/neu to urinary creatinin levels were significantly higher in high-grade tumors. HER2/neu, the sensitivity of the test was found to be 20.5%, and the specificity was 97.5%, also for the urinary HER2/neu/urinary creatinine ratio, the sensitivity and specificity of the test were found to be 31.8% and 87.5%, respectively. Conclusions: Urinary HER2/neu and ratio of urinary creatinine urine were significantly higher in patients with bladder cancer compared to healthy subjects. Large series and controlled studies are needed for use as a tumor marker.

To investigate the changes in serum YKL-40 level and humoral immune function and their significance in children with recurrent pneumonia. Blood samples were collected from 30 children with recurrent pneumonia (recurrent pneumonia group), 30 children with acute pneumonia (acute pneumonia group), and 30 healthy children (control group). Serum YKL-40 levels were measured by enzyme-linked immunosorbent assay. The correlation between serum YKL-40 level and laboratory indices related to humoral immune function was analyzed. The receiver operating characteristic (ROC) curve was used to analyze the diagnostic value of serum YKL-40 level for recurrent pneumonia. The recurrent pneumonia group had a significantly higher serum YKL-40 level than the acute pneumonia and control groups (Ppneumonia group had a significantly higher serum YKL-40 level than the control group (Ppneumonia group were significantly lower than in the acute pneumonia group (Ppneumonia was 0.958 (95%CI: 0.921-0.994). Humoral immune function is low in children with recurrent pneumonia. Serum YKL-40 may be involved in the occurrence of recurrent pneumonia and can be used as a reference index for diagnosing recurrent pneumonia.

Objective: To study the clinical significance of perioperative changes of serum IL-10 level in patients with benign and malignant pulmonary diseases. Methods: Serum IL-10 levels in patients with benign (n=17) and malignant (n=25) pulmonary diseases were measured before and 1, 3, 7, 14 days after operation with RIA. Values in 82 controls were also taken. Results: The preoperative levels of serum IL-10 in patients with lung cancer were significantly higher than those in other groups (p 0.05); The levels of serum IL-10 in 36.4% of all the patients with lung cancer on day 14 were higher than the upper limit of the normal value. In patients with benign lung diseases, perioperative changes were slight and non-significant. Conclusion: Serum IL-10 level is a reliable parameter for distinguishing benign lung disease from malignant ones. Defining preoperative and postoperative changes of serum IL-10 levels might be of prognostic value in patients with lung cancer

Unit Roots in Economic and Financial Time Series: A Re-Evaluation at the Decision-Based Significance Levels

Directory of Open Access Journals (Sweden)

Jae H. Kim

2017-09-01

Full Text Available This paper re-evaluates key past results of unit root tests, emphasizing that the use of a conventional level of significance is not in general optimal due to the test having low power. The decision-based significance levels for popular unit root tests, chosen using the line of enlightened judgement under a symmetric loss function, are found to be much higher than conventional ones. We also propose simple calibration rules for the decision-based significance levels for a range of unit root tests. At the decision-based significance levels, many time series in Nelson and Plosser’s (1982 (extended data set are judged to be trend-stationary, including real income variables, employment variables and money stock. We also find that nearly all real exchange rates covered in Elliott and Pesavento’s (2006 study are stationary; and that most of the real interest rates covered in Rapach and Weber’s (2004 study are stationary. In addition, using a specific loss function, the U.S. nominal interest rate is found to be stationary under economically sensible values of relative loss and prior belief for the null hypothesis.

'This report summarizes the first year''s progress of research funded under the Department of Energy''s Environmental Management Science Program. The research was initiated to better determine ecological risks from toxic and radioactive contaminants. More precisely, the research is designed to determine the relevancy of sublethal cellular damage to the performance of individuals and to identify characteristics of non-human populations exposed to chronic, low-level radiation, as is typically found on many DOE sites. The authors propose to establish a protocol to assess risks to non-human species at higher levels of biological organization by relating molecular damage to more relevant responses that reflect population health. They think that they can achieve this by coupling changes in metabolic rates and energy allocation patterns to meaningful population response variables, and by using novel biological dosimeters in controlled, manipulative dose/effects experiments. They believe that a scientifically defensible endpoint for measuring ecological risks can only be determined once its understood the extent to which molecular damage from contaminant exposure is detrimental at the individual and population levels of biological organization.'

To explore the clinical significance of calcitonin gene-related peptide (CGRP) levels in patients with chronic periodontitis before and after treatment, and to detect the calcitonin gene-related peptide content in human venous blood. Thirty healthy controls and thirty patients with mild, moderate, severe periodontitis were enrolled from August 2014 to June 2015.CGRP level in the patients' peripheral blood was detected by ELISA. Three months after periodontal treatment, CGRP level in mild, moderate, severe periodontitis patients' peripheral blood was re-examined by ELISA. Then the correlation between calcitonin gene-related peptide and inflammation of chronic periodontitis was analyzed with SPSS 22.0 software package. The content of CGRP in healthy controls was significantly higher than that in patients with periodontitis. With the aggravation of periodontal inflammation, blood level of CGRP decreased gradually, and the lowest was in patients with severe periodontitis (Pperiodontal treatment, CGRP content was significantly higher compared with that before treatment (Pperiodontitis (P>0.05). The level of CGRP in venous blood decreased with the increasing severity of chronic periodontitis, and CGRP was negatively correlated with the degree of inflammation of chronic periodontitis. CGRP may be involved in the occurrence and development of chronic periodontitis. CGRP content in serum of patients with chronic periodontitis after treatment was significantly increased, CGRP may be used as the basis for clinical detection of chronic periodontitis.

Safety at basic nuclear facilities other than nuclear power plants. Lessons learned from significant events reported in 2011 and 2012

International Nuclear Information System (INIS)

2014-01-01

The third report on the safety of basic nuclear installations in France other than power reactors presents an IRSN's analysis of significant events reported to the Nuclear Safety Authority in the years 2011 and 2012. It covers plants, laboratories, research reactors and facilities for the treatment, storage or disposal of waste. This report aims to contribute to a better understanding by stakeholders and more widely by the public of the safety and radiation protection issues associated with the operation of nuclear facilities, the progress made in terms of safety as well as the identified deficiencies. The main trend shows, once again, the significant role of organizational and human factors in the significant events that occurred in 2011 and 2012, of which the vast majority are without noteworthy consequences. Aging mechanisms are another major cause of equipment failure and require special attention. The report also provides IRSN's analysis of specific events that are particularly instructive for facility safety and a synthesis of assessments performed by IRSN on topics that are important for safety and radiation protection. IRSN also includes an overview of its analysis of measures proposed by licensees for increasing the safety of their facilities after the March 2011 accident at the Fukushima Daiichi nuclear power plant in Japan, which consist of providing a 'hardened safety core' to confront extreme situations (earthquake, flooding, etc.) that are unlikely but plausible and can bring about levels of hazards higher than those taken into account in the design of the facilities

Objective: To explore the clinical significance of changes of serum TRAb levels in patients with relapsing Graves' disease. Methods: Serum TRAb (with RRA) and several other thyroid-related hormones (TT 4 , TT 3 , TSH, FT 3 , with CLIA) were determined in the following subjects: 1. 25 cases of relapsing Graves' disease after previous successful treatment; 2. 18 cases of recently diagnosed Graves' disease; 3. 31 cases of successfully treated Graves' disease; 4. 15 cases of simple goiter; 5. 10 cases of nodular goiter; 6. 18 cases of hypothyroidism due to Hashimoto disease. Results: Positive rate of TRAb was 76.00% in patients with relapsing Graves' disease and 77.78% in recently diagnosed Graves' disease cases, both being significantly higher than that in all the other sets of patients studied (P<0.01). Conclusion: Determination of serum TRAb levels was helpful for the diagnosis of relapse in Graves' disease

1991 annual report on low-level radioactive waste management progress

International Nuclear Information System (INIS)

1992-11-01

This report summarizes the progress during 1991 of States and compact regions in establishing new low-level radioactive waste disposal capacity. It has been prepared in response to requirements in Section 7 (b) of Title I of Public Law 99-240, the Low-Level Radioactive Waste Policy Amendments Act of 1985 (the Act). By the end of 1991, 9 compact regions (totaling 42 States) were functioning with plans to establish low-level radioactive waste disposal facilities: Appalachian, Central, Central Midwest, Midwest, Northeast, Northwest, Rocky Mountain, Southeast, and Southwestern. Also planning to construct disposal facilities, but unaffiliated with a compact region, are Maine, Massachusetts, New York, Texas, and Vermont. The District of Columbia, New Hampshire, Puerto Rico, Rhode Island and Michigan are unaffiliated with a compact region and do not plan to construct a disposal facility. Michigan was the host State for the Midwest compact region until July 1991 when the Midwest Interstate Compact Commission revoked Michigan's membership. Only the Central, Central Midwest, and Southwestern compact regions met the January 1, 1992, milestone in the Act to submit a complete disposal license application. None of the States or compact regions project meeting the January 1, 1993, milestone to have an operational low-level radioactive waste disposal facility. Also summarized are significant events that occurred in low-level radioactive waste management in 1991 and early 1992, including the 1992 United States Supreme Court decision in New York v. United States in which New York challenged the constitutionality of the Act, particularly the ''take-title'' provision. Summary information is also provided on the volume of low-level radioactive waste received for disposal in 1991 by commercially operated low-level radioactive waste disposal facilities

Objective: To explore the clinical significance of the changes of serum insulinlike growth factor II (IGF-II) levels in patients with chronic obstruive pulmonary diseases (COPD). Methods: The serum IGF-II levels was determined with radioimmunoassay in 60 patients with COPD and 30 controls. Results: The serum IGF-II levels in patients with COPD were significantly higher than those in controls (0.65 ± 0.22μg/L vs 0.51±0.18μg/L, P<0.01). There were no significant differences among the levels in patients of different stages (stages I, II, III). Levels of IGF-II were significantly higher in patients succumbed to the dis- ease than those in patients recoverd (P<0.05). Conclusion: Serum IGF-II levels were significantly increased in patients with COPD, especially in those succumbed. (authors)

Low-level waste workshops. Final report

International Nuclear Information System (INIS)

1983-01-01

The Low-Level Radioactive Waste Policy Act of 1980 specifies that each state is responsible for the disposal of the low-level waste which is generated within its boundaries. The Act states that such wastes can be most safely and efficiently managed on a regional basis through compacts. It also defines low-level waste as waste which is not classified as high-level radioactive waste, transuranic waste, spent nuclear fuel, or by-product material as defined in the Atomic Energy Act of 1954. The Policy Act also stipulates that regional agreements or compacts shall not be applicable to the transportation, management, or disposal of low-level radioactive waste from atomic energy defense activities or federal research and development activities. It also specifies that agreements or compacts shall take affect on January 1, 1986, upon Congressional approval. In February 1983, the US Department of Energy awarded a grant to the Council of State Governments' Midwestern Office. The grant was to be used to fund workshops for legislation on low-level radioactive waste issues. The purpose of the workshops was to provide discussion specifically on the Midwest Interstate Compact on Low-Level Radioactive Waste. Legislators from the states which were eligible to join the compact were invited: Delaware, Illinois, Indiana, Iowa, Kentucky, Maryland, Michigan, Minnesota, Missouri, North Dakota, Ohio, South Dakota and Wisconsin. Virginia, Kansas and Nebraska were also eligible but had joined other compacts. Consequently, they weren't invited to the workshops. The Governor's office of West Virginia expressed interest in the compact, and its legislators were invited to attend a workshop. Two workshops were held in March. This report is a summary of the proceedings which details the concerns of the compact and expresses the reasoning behind supporting or not supporting the compact

The extent to which the sleeping brain processes sensory information remains unclear. This is particularly true for continuous and complex stimuli such as speech, in which information is organized into hierarchically embedded structures. Recently, novel metrics for assessing the neural representation of continuous speech have been developed using noninvasive brain recordings that have thus far only been tested during wakefulness. Here we investigated, for the first time, the sleeping brain's capacity to process continuous speech at different hierarchical levels using a newly developed Concurrent Hierarchical Tracking (CHT) approach that allows monitoring the neural representation and processing-depth of continuous speech online. Speech sequences were compiled with syllables, words, phrases, and sentences occurring at fixed time intervals such that different linguistic levels correspond to distinct frequencies. This enabled us to distinguish their neural signatures in brain activity. We compared the neural tracking of intelligible versus unintelligible (scrambled and foreign) speech across states of wakefulness and sleep using high-density EEG in humans. We found that neural tracking of stimulus acoustics was comparable across wakefulness and sleep and similar across all conditions regardless of speech intelligibility. In contrast, neural tracking of higher-order linguistic constructs (words, phrases, and sentences) was only observed for intelligible speech during wakefulness and could not be detected at all during nonrapid eye movement or rapid eye movement sleep. These results suggest that, whereas low-level auditory processing is relatively preserved during sleep, higher-level hierarchical linguistic parsing is severely disrupted, thereby revealing the capacity and limits of language processing during sleep. SIGNIFICANCE STATEMENT Despite the persistence of some sensory processing during sleep, it is unclear whether high-level cognitive processes such as speech

2010-07-01

The present study addressed convergence between self-report and indirect approaches to assessing dependency. We were moderately successful in validating an implicit measure, which was found to be reliable, orthogonal to 2 self-report instruments, and predictive of external criteria. This study also examined discrepancies between scores on self-report and implicit measures, and has implications for their significance. The possibility that discrepancies themselves are pathological was not supported, although discrepancies were associated with particular personality profiles. Finally, this study offered additional evidence for the relation between dependency and depressive symptomatology and identified implicit dependency as contributing unique variance in predicting past major depression.

Objective: To investigate the changes of serum levels of insulin-like growth factor II (IGF II) and adrenomedullin (ADM) in patients with essential hypertension. Methods: Serum IGF II and ADM levels were measured in 62 cases of hypertension and 40 controls with RIA. Results: Serum IGF II and ADM levels were significantly bigger in hypertensive patients than those in the controls (t = 4.454, p < 0.01; t = 3.992, p < 0.01). The serum IGF II level was significantly positively correlated to the serum ADM levels (r = 0.379, p < 0.05) and both were significantly positively correlated to the mean arterial pressure (r = 0.346, r = 0.353, p < 0.05) but not with BMI. Serum ADM levels increased gradually as the disease progressed from stage I to stage III (p < 0.05) with levels in stage III markedly higher than those in stage I (p < 0.01). In EH patients with heart and/or brain and/or renal complications the serum ADM levels were significantly higher than those in EH patients without complications (t = 2.050, p < 0.05). Such differences did not exist in the case of IGF II. Conclusion: Serum IGF II and ADM levels were increased markedly in hypertensive patients. These two factors were mutually positively correlated and both were positively correlated to mean arterial pressure. ADM levels increased gradually as the disease progressing but IGF II levels remained stable

Objective: To study the clinical significance of the changes of serum BNP levels in patients with heart failure (HF). Methods: Serum BNP levels in 88 patients with HF(NYHA II-IV), 20 patients with compensated cardiac function (NYHA I) and 30 controls were determined with RIA. Results: The serum BNP levels in patients with HF (264±63.9 pmol/L) were significantly higher than those in patients with compensated cardiac function (NYHA I, 11.6±4.7 pmol/L, t=2.133, p 0.05). As the cardiac function deteriorated from NYHA II to NYHA IV, the BNP levels increased consecutively with significant differences from each other (F=2.595, p<0.05). BNP levels in patients with acute left heart failure were significantly higher than those in patients with chronic heart failure (t=2.268, p<0.05) and fell promptly at relief of the attack (p<0.05). Conclusion: Determination of serum BNP levels in patients with HF was helpful to the study of the severity and prognosis of the disease

To study the changes in bone metabolic parameters and serum thyroid hormone levels in patients with hyperthyroidism, seventy patients with hyperthyroidism and sixty healthy controls were investigated by means of radioimmunoassay (RIA) for serum ICTP, chemiluminescent immunoassay for BAP and serum thyroid hormone and meanwhile bone mineral density was measured. The results showed that the levels of serum BAP, ICTP and thyroid hormone in patients with hyperthyroidism were dramatically higher than those in control group (all P<0.01), BMD was significantly decreased in the study group (P<0.01). The correlation analysis showed that both BAP and ICTP were negatively correlated with BMD (all P<0.05). The results from this investigation indicated that increased bone turnover is significantly associated with an increased thyroid hormone in patients with hyperthyroidism, and bone resorption is greater than formation resulting in a bone mass loss. Measurement of serum BAP and ICTP levels may be of help to judge the severity of bone metabolism, study the state of an illness in hyperthyroidism

We report here on an unusual case of multiple levels of asymmetric lumbar spondylolysis in a 19-year-old woman. The patient had severe low back pain of increasing intensity with lumbar instability, which was evident on the dynamic radiographs. MRI demonstrated the presence of abnormalities and the three dimensional CT scan revealed asymmetric complete spondylolysis at the left L2, L3 and L4 levels and the right L1, L2 and L3 levels. This case was treated surgically by posterior and posterolateral fusion at L2-3-4 with intersegmental fixation using pedicle screws and an auto iliac bone graft. The patient was relieved of her low back pain after the surgery. PMID:20404945

Methods: The sera of 67 esophageal carcinoma patients and 30 healthy control cases were collected. The VEGF level in serum samples were measured with enzyme-linked immunosorbent assay (ELISA) method. The relations among VEGF level changes,clinical stages and radiotherapy effect were analyzed. Results: The VEGF levels of patients with esophagus cancer before, during and after radiotherapy were significantly higher than those in control group (F=11.65, P<0.01). The VEGF level after radiotherapy was significant lower than that before radiotherapy (F=10.72, P<0.01). The average VEGF level of patients with T 3 and T 4 was significantly higher than that of control group (F=14.10, P<0.01). The average VEGF level of patients with N 1 and N 2 was significantly higher than that of control group (F=8.64, P<0.01). In 62 patients,the serum VEGF level increased in 21 cases but decreased in 41 cases after radiotherapy. With difference in radiotherapy efficiency of 61.90% and 90.24%, respectively (χ 2 =6.08, P<0.05). The average VEGF level during and after radiotherapy for 50 cases of CR + PR were significantly lower than that before radiotherapy (F=7.98, P<0.01). Conclusions: Monitoring the serum VEGF level of patients with esophagus cancer can help evaluate the radiosensitivity, which has a significance in predicting the prognosis of radiotherapy. (authors)

Hanson, C S; Nabavi, D; Yuen, H K

2001-01-01

The purpose of this study was to determine whether participation in sports by persons with spinal cord injuries (SCIs) affected level of community integration as defined by the World Health Organization and as measured by the Craig Handicap Assessment and Reporting Technique (CHART). Forty-eight participants were recruited from a camp for persons with physical disabilities as well as from SCI support groups. Participants were divided into groups of athletes (n = 30) and nonathletes (n = 18) on the basis of their self-reported level of sports participation. Athletes scored significantly higher on four of five subsections of the CHART (physical independence, mobility, occupation, social integration), indicating greater levels of community integration than nonathletes. These findings extend the literature outlining the physical and psychological benefits of sports. Occupational therapists have a unique opportunity to use the occupation of sports to integrate the roots of the profession with the cultural demands of society.

Full Text Available Alpha-synuclein (α-synuclein and beta-synuclein (β-synuclein are presynaptic proteins playing important roles in neuronal plasticity and synaptic vesicle regulation. To evaluate the association of these two proteins and autism spectrum disorder (ASD, we investigated the plasma α-synuclein and β-synuclein levels in 39 male children with ASD (2 subgroups: 25 autism and 14 pervasive developmental disorder-not otherwise specified (PDD-NOS comparing with 29 sex- and age-matched controls by using enzyme-linked immunosorbent assay (ELISA. We first determined the levels of these two proteins in the ASD subgroups and found that there were no significant differences in both plasma α-synuclein and β-synuclein levels in the autism and PDD-NOS groups. Thus, we could combine the 2 subgroups into one ASD group. Interestingly, the mean plasma α-synuclein level was significantly lower (P<0.001 in the ASD children (10.82±6.46 ng/mL than in the controls (29.47±18.62 ng/mL, while the mean plasma β-synuclein level in the ASD children (1344.19±160.26 ng/mL was significantly higher (P<0.05 than in the controls (1219.16±177.10 ng/mL. This is the first study examining the associations between α-synuclein and β-synuclein and male ASD patients. We found that alterations in the plasma α-synuclein and β-synuclein levels might be implicated in the association between synaptic abnormalities and ASD pathogenesis.

Development of disposal sites for low-level radioactive waste is a complicated legal, regulatory and public sector process. Development of the low-level radioactive waste disposal facility to support generators in Illinois and Kentucky is well under way. Significant progress has been made to re-engineer the siting development process capitalizing on prior lessons learned and a recommitment from Illinois state leadership assuring the future success of the program. Comparisons of why this new process will succeed are the major focus of this paper. Specific changes in approach from the previous process including changes in the Illinois Management Act (Management Act), creation of the Illinois Low-Level Radioactive Waste Siting Task Group (Task Group), new roles for the Illinois State Geologic Survey and Illinois State Water Survey (Scientific Surveys) and the Illinois Department of Nuclear Safety (IDNS), a new contractor reliance approach and increased confidence on the open-quote science close-quote are the major contrasts between the previous process and the new process currently underway

The objective of the present survey was to study self-reported sleep disturbances due to railway noise with respect to nighttime equivalent noise level (L(p,A,eq,night)) and maximum noise level (L(p,A,max)). A sample of 1349 people in and around Oslo in Norway exposed to railway noise was studied in a cross-sectional survey to obtain data on sleep disturbances, sleep problems due to noise, and personal characteristics including noise sensitivity. Individual noise exposure levels were determined outside of the bedroom facade, the most-exposed facade, and inside the respondents' bedrooms. The exposure-response relationships were analyzed by using logistic regression models, controlling for possible modifying factors including the number of noise events (train pass-by frequency). L(p,A,eq,night) and L(p,A,max) were significantly correlated, and the proportion of reported noise-induced sleep problems increased as both L(p,A,eq,night) and L(p,A,max) increased. Noise sensitivity, type of bedroom window, and pass-by frequency were significant factors affecting noise-induced sleep disturbances, in addition to the noise exposure level. Because about half of the study population did not use a bedroom at the most-exposed side of the house, the exposure-response curve obtained by using noise levels for the most-exposed facade underestimated noise-induced sleep disturbance for those who actually have their bedroom at the most-exposed facade.

Background Currently, one of the causes of high morbidity and mortality is injuries. Predict the outcome of injuries - it is an important task of the treating physician. Trauma is a stress factor so to predict the outcome, you can use markers of stress, the most accessible ofwhich is blood glucose. to reveal the dynamics of the relationship between blood glucose levels and the outlook for the life ofpatients with thoracoabdominal injuries. A retrospective analysis of medical records of hospitalized patients were divided into two groups, depending on the outlook for the life of (favorable or unfavorable), and each of the groups - into two subgroups according to the presence or absence of signs of intoxication at admission. The subgroups were calculated and compared the mean blood glucose levels at different hours of hospital treatment. It was found that the average blood glucose levels at various hours of hospital stay were significantly higher in patients with poor outcome. The most noticeable was the difference in the first days of hospital treatment. Signs of intoxication was associated with lower values of glucose and a tendency to hypoglycaemia. In addition, among patients with high blood glucose ( 8 mg / dL) was observed over deaths in the first day of hospital stay. High blood glucose levels ( 8,0 mmol / L) in the first day of hospital treatment is a predictor ofpoor outcome in patients with thoracoabdominal injuries.

Carcinoembryonic antigen (CEA) has been studied in the field of gynecologic malignancy to determine whether it can be used as a tumor marker for early detection of recurrence or evaluation of therapeutic results. From January 1985 through December 1989, a total of 239 cervical cancer patients were entered for an analysis of plasma CEA level in the group with cervical cancer compared to the control group consisting of 65 normal healthy women and 18 women with benign gynecologic disease. Plasma CEA levels appear to be directly related with the tumor extension and as stages advance, the incidence of patients with abnormal plasma CEA levels is increased. Also, there seems to be a little higher incidence of abnormal CEA levels in patients with adenocarcinomas or adenosquamous carcinoma but not statistically significant because of small number of patients. When the patients developed recurrence, plasma CEA levels are markedly elevated in the majority, particularly in patients with hepatic metastases. In conclusion, serial plasma CEA checks could be used to detect recurrence during follow-up after treatment of cervical cancer.

Objective: To explore the relationship between pregnancy-associated plasma protein-A (PAPP-A) and occurance, development of cardiovascular diseases, and lipids. Methods: 75 patients with coronary disease were divided into acute myocardial infarction (n=32), unstable angina pectoris (n=22) and stable angina pectoris (n=21) groups, and 60 subjects without coronary diseases were used as controls. The serum PAPP-A, IL-6, IL-10, lipids were measured in all patients and controls by different methods of enzymatically amplified two-step sandwith- type immunoassay, double antibody radio-immunoassay, ABC-HRP, auto biochemistic analytist. Results: (1) The level of PAPP-A in acute coronary syndrome (ACS, including acute myocardial infarction and unstable angina pectoris) patients was significantly higher than that in stable angina pectoris patients and controls (P<0.05). (2) There were significantly associations between PAPP-A and serum totle cholesterol, ApoA1/ApoB (r=0.348, 0.420, P<0.05). (3) The levels of IL-6 and IL-10 in coronary heart disease patients were significantly higher than those in controls (P<0.05), and the variations among acute myocardial infarction, unstable angina pectoris, stable angina pectoris patients were significantly (P<0.05). There were significantly associations between PAPP-A, IL-6 and IL-10 (Spearman r 0.446, 0.523, P<0.05). Conclusion: PAPP-A is significantly associated with occurance and development of coronary heart disease, probablely as a marker of unstable plaque in coronary heart disease. (authors)

In the mass media, sea level rise is commonly associated with the impacts of climate change due to increasing atmospheric greenhouse gases. As this issue garners ongoing international policy attention, segments of the scientific community have expressed unease about how this has been covered by mass media. Therefore, this study examines how sea level rise projections-in IPCC Assessment Reports and a sample of the scientific literature-have been represented in seven prominent United States (US) and United Kingdom (UK) newspapers over the past two decades. The research found that-with few exceptions-journalists have accurately portrayed scientific research on sea level rise projections to 2100. Moreover, while coverage has predictably increased in the past 20 years, journalists have paid particular attention to the issue in years when an IPCC report is released or when major international negotiations take place, rather than when direct research is completed and specific projections are published. We reason that the combination of these factors has contributed to a perceived problem in the sea level rise reporting by the scientific community, although systematic empirical research shows none. In this contemporary high-stakes, high-profile and highly politicized arena of climate science and policy interactions, such results mark a particular bright spot in media representations of climate change. These findings can also contribute to more measured considerations of climate impacts and policy action at a critical juncture of international negotiations and everyday decision-making associated with the causes and consequences of climate change.

Correction of the significance level when attempting multiple transformations of an explanatory variable in generalized linear models

Science.gov (United States)

2013-01-01

Background In statistical modeling, finding the most favorable coding for an exploratory quantitative variable involves many tests. This process involves multiple testing problems and requires the correction of the significance level. Methods For each coding, a test on the nullity of the coefficient associated with the new coded variable is computed. The selected coding corresponds to that associated with the largest statistical test (or equivalently the smallest pvalue). In the context of the Generalized Linear Model, Liquet and Commenges (Stat Probability Lett,71:33–38,2005) proposed an asymptotic correction of the significance level. This procedure, based on the score test, has been developed for dichotomous and Box-Cox transformations. In this paper, we suggest the use of resampling methods to estimate the significance level for categorical transformations with more than two levels and, by definition those that involve more than one parameter in the model. The categorical transformation is a more flexible way to explore the unknown shape of the effect between an explanatory and a dependent variable. Results The simulations we ran in this study showed good performances of the proposed methods. These methods were illustrated using the data from a study of the relationship between cholesterol and dementia. Conclusion The algorithms were implemented using R, and the associated CPMCGLM R package is available on the CRAN. PMID:23758852

The prognostic significance of whole blood global and specific DNA methylation levels in gastric adenocarcinoma.

Directory of Open Access Journals (Sweden)

Mansour S Al-Moundhri

Full Text Available BACKGROUND: Epigenetics, particularly DNA methylation, has recently been elucidated as important in gastric cancer (GC initiation and progression. We investigated the clinical and prognostic importance of whole blood global and site-specific DNA methylation in GC. METHODS: Genomic DNA was extracted from the peripheral blood of 105 Omani GC patients at diagnosis. DNA methylation was quantified by pyrosequencing of global DNA and specific gene promoter regions at 5 CpG sites for CDH1, 7 CpG sites for p16, 4 CpG sites for p53, and 3 CpG sites for RUNX3. DNA methylation levels in patients were categorized into low, medium, and high tertiles. Associations between methylation level category and clinicopathological features were evaluated using χ(2 tests. Survival analyses were carried out using the Kaplan-Meier method and log rank test. A backward conditional Cox proportional hazards regression model was used to identify independent predictors of survival. RESULTS: Older GC patients had increased methylation levels at specific CpG sites within the CDH1, p53, and RUNX-3 promoters. Male gender was significantly associated with reduced global and increased site-specific DNA methylation levels in CDH1, p16, and p53 promoters. Global DNA low methylation level was associated with better survival on univariate analysis. Patients with high and medium methylation vs. low methylation levels across p16 promoter CpG sites, site 2 in particular, had better survival. Multivariate analysis showed that global DNA hypermethylation was a significant independent predictor of worse survival (hazard ratio (HR = 2.0, 95% CI: 1.1-3.8; p = 0.02 and high methylation mean values across p16 promoter sites 1-7 were associated with better survival with HR of 0.3 (95% CI, 0.1-0.8; p = 0.02 respectively. CONCLUSIONS: Analysis of global and site-specific DNA methylation in peripheral blood by pyrosequencing provides quantitative DNA methylation values that may serve as important

2017-08-15

Large databases of fecal indicator bacteria (FIB) measurements are available for coastal waters. With the assistance of satellite imagery, we illustrated the power of assessing data for many sites by evaluating beach features such as geomorphology, distance from rivers and canals, presence of piers and causeways, and degree of urbanization coupled with the enterococci FIB database for the state of Florida. We found that beach geomorphology was the primary characteristic associated with enterococci levels that exceeded regulatory guidelines. Beaches in close proximity to marshes or within bays had higher enterococci exceedances in comparison to open coast beaches. For open coast beaches, greater enterococci exceedances were associated with nearby rivers and higher levels of urbanization. Piers and causeways had a minimal contribution, as their effect was often overwhelmed by beach geomorphology. Results can be used to understand the potential causes of elevated enterococci levels and to promote public health. Copyright © 2017 Elsevier Ltd. All rights reserved.

Full Text Available Background Changes in serum micro nutrients levels affect a number of critically important metabolic processes; these could potentially influence blood counts and ultimately disease presentation in patients with sickle cell anemia (SCA. Objectives To evaluate the influence of serum micro-nutrients levels; zinc, copper, selenium and magnesium on blood counts in steady state SCA patients. Methods A cross sectional study that involved 28 steady state adult SCA subjects. Seven milliliters (mls of blood was collected; 3 mls was for hemoglobin electrophoresis and full blood count determination while 4 mls was for measurement of serum micro nutrients levels, by the atomic absorption spectrophotometry. Correlation between serum micro-nutrient levels and blood counts was done by the Pearson’s linear regression. Ethical approval was obtained from the institutional review board and each participant gave informed consent. All data was analyzed by SPSS software version 20. Results There was a significant correlation between serum copper levels and mean cell hemoglobin (MCH, platelet and lymphocyte counts (r = 0.418; P = 0.02, r = -0.376; P = 0.04 and r = -0.383; P = 0.04, respectively. There were no significant correlations between serum levels of other micro nutrients (selenium, zinc and magnesium and blood counts. Conclusions Copper influences blood count in SCA patients probably by inducing red cell haemolysis, oxidant tissue damage and stimulating the immune system.

Cerebrospinal fluid (CSF) 42 amino acid species of amyloid beta (Aβ42) and tau levels are strongly correlated with the presence of Alzheimer's disease (AD) neuropathology including amyloid plaques and neurodegeneration and have been successfully used as endophenotypes for genetic studies of AD. Additional CSF analytes may also serve as useful endophenotypes that capture other aspects of AD pathophysiology. Here we have conducted a genome-wide association study of CSF levels of 59 AD-related analytes. All analytes were measured using the Rules Based Medicine Human DiscoveryMAP Panel, which includes analytes relevant to several disease-related processes. Data from two independently collected and measured datasets, the Knight Alzheimer's Disease Research Center (ADRC) and Alzheimer's Disease Neuroimaging Initiative (ADNI), were analyzed separately, and combined results were obtained using meta-analysis. We identified genetic associations with CSF levels of 5 proteins (Angiotensin-converting enzyme (ACE), Chemokine (C-C motif) ligand 2 (CCL2), Chemokine (C-C motif) ligand 4 (CCL4), Interleukin 6 receptor (IL6R) and Matrix metalloproteinase-3 (MMP3)) with study-wide significant p-values (pprocessing and pro-inflammatory signaling. SNPs associated with ACE, IL6R and MMP3 protein levels are located within the coding regions of the corresponding structural gene. The SNPs associated with CSF levels of CCL4 and CCL2 are located in known chemokine binding proteins. The genetic associations reported here are novel and suggest mechanisms for genetic control of CSF and plasma levels of these disease-related proteins. Significant SNPs in ACE and MMP3 also showed association with AD risk. Our findings suggest that these proteins/pathways may be valuable therapeutic targets for AD. Robust associations in cognitively normal individuals suggest that these SNPs also influence regulation of these proteins more generally and may therefore be relevant to other diseases.

Full Text Available Abstract Background Evidence suggests possible synergetic effects of multiple lifestyle behaviors on health risks like obesity and other health outcomes. Therefore it is important to investigate associations between dietary and physical activity behavior, the two most important lifestyle behaviors influencing our energy balance and body composition. The objective of the present study is to describe the relationship between energy, nutrient and food intake and the physical activity level among a large group of European adolescents. Methods The study comprised a total of 2176 adolescents (46.2% male from ten European cities participating in the HELENA (Healthy Lifestyle in Europe by Nutrition in Adolescence study. Dietary intake and physical activity were assessed using validated 24-h dietary recalls and self-reported questionnaires respectively. Analyses of covariance (ANCOVA were used to compare the energy and nutrient intake and the food consumption between groups of adolescents with different physical activity levels (1st to 3rd tertile. Results In both sexes no differences were found in energy intake between the levels of physical activity. The most active males showed a higher intake of polysaccharides, protein, water and vitamin C and a lower intake of saccharides compared to less active males. Females with the highest physical activity level consumed more polysaccharides compared to their least active peers. Male and female adolescents with the highest physical activity levels, consumed more fruit and milk products and less cheese compared to the least active adolescents. The most active males showed higher intakes of vegetables and meat, fish, eggs, meat substitutes and vegetarian products compared to the least active ones. The least active males reported the highest consumption of grain products and potatoes. Within the female group, significantly lower intakes of bread and cereal products and spreads were found for those reporting to

We have previously reported that administration of a CD11d monoclonal antibody (mAb) improves recovery in a clip-compression model of SCI. In this model the CD11d mAb reduces the infiltration of activated leukocytes into the injured spinal cord (as indicated by reduced intraspinal MPO). However not all anti-inflammatory strategies have reported beneficial results, suggesting that success of the CD11d mAb treatment may depend on the type or severity of the injury. We therefore tested the CD11d mAb treatment in a rat hemi-contusion model of cervical SCI. In contrast to its effects in the clip-compression model, the CD11d mAb treatment did not improve forelimb function nor did it significantly reduce MPO levels in the hemi-contused cord. To determine if the disparate results using the CD11d mAb were due to the biomechanical nature of the cord injury (compression SCI versus contusion SCI) or to the spinal level of the injury (12th thoracic level versus cervical) we further evaluated the CD11d mAb treatment after a T12 contusion SCI. In contrast to the T12 clip compression SCI, the CD11d mAb treatment did not improve locomotor recovery or significantly reduce MPO levels after T12 contusion SCI. Lesion analyses revealed increased levels of hemorrhage after contusion SCI compared to clip-compression SCI. SCI that is accompanied by increased intraspinal hemorrhage would be predicted to be refractory to the CD11d mAb therapy as this approach targets leukocyte diapedesis through the intact vasculature. These results suggest that the disparate results of the anti-CD11d treatment in contusion and clip-compression models of SCI are due to the different pathophysiological mechanisms that dominate these two types of spinal cord injuries.

This report summarizes data on low-level radioactive waste (LLRW) generated in New York State: it is based on reports from generators that must be filed annually with the New York State Energy Research and Development Authority (NYSERDA) and on data from the US Department of Energy (US DOE). The New York State Low-Level Radioactive Waste Management Act (State Act) requires LLRW generators in the State to submit annual reports detailing the classes and quantities of waste generated. This is the 13th year generators have been required to submit these reports to NYSERDA. The data are summarized in a series of tables and figures. There are four sections in the report. Section 1 covers volume, activity, and other characteristics of waste shipped for disposal in 1998. Activity is the measure of a material's radioactivity, or the number of radiation-emitting events occurring each second. Section 2 summarizes volume, activity, and other characteristics of waste held for storage as of December 31, 1998. Section 3 shows historical LLRW generation and includes generators' projections for the next five years. Section 4 provides a list, by county, of all facilities from which 1998 LLRW reports were received. 2 figs., 23 tabs

LuAnn L. Brink

2013-01-01

Full Text Available Introduction. Although lead paint and leaded gasoline have not been used in the US for thirty years, thousands of US children continue to have blood lead levels (BLLs of concern. Methods. We investigated the potential association of modeled air lead levels and BLLs ≥ 10 μg/dL using a large CDC database with BLLs on children aged 0–3 years. Percent of children with BLLs ≥ 10 μg/dL (2000–2007 by county and proportion of pre-50 housing and SES variables were merged with the US EPA's National Air Toxics Assessment (NATA modeled air lead data. Results. The proportion with BLL ≥ 10 μg/dL was 1.24% in the highest air lead counties, and the proportion with BLL ≥ 10 μg/dL was 0.36% in the lowest air lead counties, resulting in a crude prevalence ratio of 3.4. Further analysis using multivariate negative binomial regression revealed that NATA lead was a significant predictor of % BLL ≥ 10 μg/dL after controlling for percent pre-l950 housing, percent rural, and percent black. A geospatial regression revealed that air lead, percent older housing, and poverty were all significant predictors of % BLL ≥ 10 μg/dL. Conclusions. More emphasis should be given to potential sources of ambient air lead near residential areas.

To evaluate the frequency, number and signal intensity of fluid-fluid levels of musculoskeletal diseases on MR images, and to determine the usefulness of this information for the differentiation of musculoskeletal diseases. MR images revealed fluid-fluid levels in the following diseases : giant cell tumor(6), telangiectatic osteosarcoma(4), aneurysmal bone cyst(3), synovial sarcoma(3), chondroblastoma(2), soft tissue tuberculous abscess(2), hematoma(2), hemangioma (1), neurilemmoma(1), metastasis(1), malignant fibrous histiocytoma(1), bursitis(1), pyogenic abscess(1), and epidermoid inclusion cyst(1). Fourteen benign tumors and ten malignant, three abscesses, and the epidermoid inclusion cyst showed only one fluid-fluid level in a unilocular cyst. On T1-weighted images, the signal intensities of fluid varied, but on T2-weighted images, superior layers were in most cases more hyperintense than inferior layers. Because fluid-fluid layers are a nonspecific finding, it is difficult to specifically diagnose each disease according to the number of fluid-fluid levels or signal intensity of fluid. In spite of the nonspecificity of fluid-fluid levels, they were frequently seen in cases of giant cell tumor, telangiectatic osteosarcoma, aneurysmal bone cycle, and synovial sarcoma. Nontumorous diseases such abscesses and hematomas also demonstrated this finding. (author). 11 refs., 1 tab., 4 figs.

Using negative binomial and multi-level Poisson models, the authors determined the statistical significance of agricultural and socio-economic risk factors for rates of reported disease associated with Escherichia coli O157 in census subdivisions (CSDs) in Alberta, Canada, 2000-2002. Variables relating to population stability, aboriginal composition of the CSDs, and the economic relationship between CSDs and urban centres were significant risk factors. The percentage of individuals living in low-income households was not a statistically significant risk factor for rates of disease. The statistical significance of cattle density, recorded at a higher geographical level, depended on the method used to correct for overdispersion, the number of levels included in the multi-level models, and the choice of using all reported cases or only sporadic cases. Our results highlight the importance of local socio-economic risk factors in determining rates of disease associated with E. coli O157, but their relationship with individual risk factors requires further evaluation.

Objective: To explore the clinical significance of changes of gingival crevicular fluid levels of interleukin-10 (IL-10), interleukin-18 (IL-18) and interferon-γ were determined with RIA in 42 patients with periodontitis both before and after trentment as well as in 30 controls. Results: Before treatment, the gingival crevicular fluid level of IL-18 and IFN-γ in the patients were significant higher than those in controls (P 0.05). After one month of treatment, the gingival crevigcular fluid levels of IL-18 and IFN-γ were markedly dropped, but remained significantly higher than those in controls (P<0.05). The gingival crevicular fluid levels of IL-10 were markedly dropped, but remained significantly higher than those in controls (P<0.05). The gingival crevicular fluid levels of IL-10 were significant higher than those in controls (P<0.01). The gingival fluid contents of IL-10 and IL-18 were positively correlated with the depth of periodontal pouch and looseness of attachment (r= 0.2617, r= 0.2802, P<0.05) but the interferon-γ contents were negatively correlated (r= -0.1743, P<0.05). Conclusion: The changes of gingival carvacrol fluid levels of interleukin-10, interleukin-18 and If-γ in patients with periodontics suggested that there were disturbances of immunomodulation.

Interpersonal factors play a major role in causing and maintaining depression. This study sought to investigate how patients' self-perceived interpersonal problems and impact messages as perceived by significant others are interrelated, change over therapy, and differentially predict process and outcome in psychotherapy of depression. For the present study, we used data from 144 outpatients suffering from major depression that were treated within a psychotherapy study. Interpersonal variables were assessed pre- and posttherapy with the self-report Inventory of Interpersonal Problems-Circumplex Scale (IIP-32; Thomas, Brähler, & Strauss, 2011) and with the informant-based Impact Message Inventory (Caspar, Berger, Fingerle, & Werner, 2016). Patients' levels on the dimensions of Agency and Communion were calculated from both measures; their levels on Interpersonal Distress were measured with the IIP. Depressive and general symptomatology was assessed at pre-, post-, and at 3-month follow-up; patient-reported process measures were assessed during therapy. The Agency scores of IIP and IMI correlated moderately, but the Communion scores did not. IIP Communion was positively associated with the quality of the early therapeutic alliance and with the average level of cognitive-emotional processing during therapy. Whereas IIP Communion and IMI Agency increased over therapy, IIP Distress decreased. A pre-post-decrease in IIP Distress was positively associated with pre-postsymptomatic change over and above the other interpersonal variables, but pre-post-increase in IMI Agency was positively associated with symptomatic improvement from post- to 3-month follow-up. These findings suggest that significant others seem to provide important additional information about the patients' interpersonal style. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

To test the hypothesis that the effects of an experimental occlusal interference differ between individuals reporting a high or low frequency of wake-time oral parafunctions. Study participants reporting very high (HFP group; n = 10) or very low (LFP group; n = 10) levels of oral parafunctions were selected by means of a questionnaire administered to 200 medical students. The selected participants wore an experimental occlusal interference in a single-blind longitudinal study, which comprised different occlusal conditions: interference free (IFC) and active occlusal interference (AIC). Assessments included clinical examination, measurements of nonfunctional tooth contacts, state and trait anxiety, and visual analog scale scores for occlusal discomfort, masticatory muscle pain, and headache. Data were analyzed by repeated measures twoway analysis of variance on ranked data, followed by calculation of within- and between-group differences using Friedman tests and Mann-Whitney tests, respectively. During AIC, the frequency of nonfunctional tooth contacts significantly decreased in both groups (median [interquartile range, IQR]: in HFP from 55.3% [60.0%] to 31.1% [33.5%], P = .03; in LFP from 31.8% [32.4%] to 14.0% [22.8%], P interference caused more occlusal discomfort in the HFP group than in the LFP group (P = .02) and was associated with a significant increase of masticatory muscle pain (P = .05) and headache (P = .04) only in the HFP group. The application of an experimental occlusal interference has a different effect in individuals reporting a high or low frequency of oral parafunctions.

 Activated protein C (APC) is a major regulator of thrombin formation. Two major plasma inhibitors form complexes with APC, protein C inhibitor (PCI) and α 1 -antitrypsin (α 1 AT), and these complexes have been quantified by specific enzyme-linked immunosorbent assays (ELISAs). Also, complexes of APC with α 2 -macroglobulin (α 2 M) have been observed by immunoblotting. Here, we report an ELISA for APC:α 2 M complexes in plasma.  Plasma samples were pre-treated with dithiothreitol and then with iodoacetamide. The detection range of the newly developed APC:α 2 M assay was 0.031 to 8.0 ng/mL of complexed APC. Following infusions of APC in humans and baboons, complexes of APC with α 2 M, PCI and α 1 AT were quantified. These complexes as well as circulating APC were also measured in 121 patients with a history of venous thromboembolism (VTE) and 119 matched controls.  In all the in vivo experiments, α 2 M was a significant APC inhibitor. The VTE case-control study showed that VTE patients had significantly lower APC:α 2 M and APC levels than the controls ( p  APC:α 2 M or the lowest quartile of APC had approximately four times more VTE risk than those in the highest quartile of APC:α 2 M or of APC. The risk increased for individuals with low levels of both parameters.  The APC:α 2 M assay reported here may be useful to help monitor the in vivo fate of APC in plasma. In addition, our results show that a low APC:α 2 M level is associated with increased VTE risk. Schattauer GmbH Stuttgart.

We examined the serum levels of testosterone (T) (total and bioavailable) dehydroepiandrosterone (DHEA), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and prostate-specific antigen (PSA) in men receiving treatment with luteinizing hormone releasing-hormone (LHRH) agonists for metastatic prostate cancer. In doing this, we want to determine the efficacy of these agents in lowering T levels and whether a possible relationship exists between PSA values, as a surrogate measure of tumour activity, and hormone levels. This was a single centre prospective study of patients on LHRH agonists. Of all the 100 eligible patients, 31 did not qualify (10 were receiving their first injection, 13 were on intermittent hormonal therapy, 7 refused to enter the trial and 1 patient's blood sample was lost). Therefore in total, 69 patients were included in the final analysis. Each patient had their blood sample drawn immediately before the administration of a LHRH agonist. The new proposed criteria of values are more commonly found in patients with suboptimal levels of testosterone receiving LHRH analogs, but the clinical importance of this finding has not been established. There is no significant difference with respect to hormonal levels reached among patients on a variety of LHRH agonists. Total testosterone determinations should be considered in patients on LHRH agonist therapy, particularly when the PSA values begin to rise since it may lead to further beneficial hormonal manipulation.

Serum lipocalin-2 levels are elevated in obese patients. We assessed serum lipocalin-2 levels in polycystic ovary syndrome (PCOS) and the effects of weight loss or metformin on these levels. Forty-seven overweight/obese patients with PCOS [body mass index (BMI) >27 kg/m(2)] were instructed to follow a low-calorie diet, to exercise and were given orlistat or sibutramine for 6 months. Twenty-five normal weight patients with PCOS (BMI weight and 25 overweight/obese healthy female volunteers comprised the control groups. Serum lipocalin-2 levels did not differ between overweight/obese patients with PCOS and overweight/obese controls (p = 0.258), or between normal weight patients with PCOS and normal weight controls (p = 0.878). Lipocalin-2 levels were higher in overweight/obese patients with PCOS than in normal weight patients with PCOS (p weight loss resulted in a fall in lipocalin-2 levels (p weight patients with PCOS, treatment with metformin did not affect lipocalin-2 levels (p = 0.484). In conclusion, PCOS per se is not associated with elevated lipocalin-2 levels. Weight loss induces a significant reduction in lipocalin-2 levels in overweight/obese patients with PCOS.

2017-12-01

Full Text Available The main objective of this paper is to find the relation between the adaptive significance level presented here and the sample size. We statisticians know of the inconsistency, or paradox, in the current classical tests of significance that are based on p-value statistics that are compared to the canonical significance levels (10%, 5%, and 1%: “Raise the sample to reject the null hypothesis” is the recommendation of some ill-advised scientists! This paper will show that it is possible to eliminate this problem of significance tests. We present here the beginning of a larger research project. The intention is to extend its use to more complex applications such as survival analysis, reliability tests, and other areas. The main tools used here are the Bayes factor and the extended Neyman–Pearson Lemma.

The authors examined siblings' reports of children's depression, anxiety, and aggression, and their reports of the sibling relationship, and compared them with children's self-reports. In two samples, including 169 sibling pairs (age M = 9.98 years, SD = 1.51), no significant differences emerged in the levels of depression and anxiety found in siblings' reports of children's behavior and children's self-reports, although siblings reported children to have significantly higher levels of aggression than the children self-reported. Age, the difference in ages between siblings, sex, and sibling sex were not related to siblings' reports of children's behavior. The relations between children's and siblings' reports of children's behavior were significant, yet moderate (average r = .22). Both siblings' self-reports of internalizing behavior and their perceptions of aspects of the sibling relationship (affection, rivalry, hostility, and satisfaction with the sibling relationship) explained significant, and unique, variance in siblings' reports of children's internalizing behavior. The findings for aggressive behavior were similar, although siblings' perceptions of affection in the sibling relationship were not significantly related to their reports of children's aggression. The potential uses and benefits of sibling reports of children's behavior, and sibling and family relationships, are discussed.

To evaluate the relationship between work engagement and psychological capital (PsyCap) levels reported by registered nurses. PsyCap is a developable human resource. Research on PsyCap as an antecedent to work engagement in nurses is needed. A convenience sample of 137 registered nurses participated in this quantitative cross-sectional survey. Questionnaires measured self-reported levels of work engagement and psychological capital. Descriptive and inferential statistics were used for data analysis. There was a statistically significant correlation between work engagement and PsyCap scores (r=0.633, pworking at band 5 level reported statistically significantly lower PsyCap scores compared with nurses working at band 6 and 7 levels. Nurses reporting high levels of work engagement also reported high levels of PsyCap. Band 5 nurses might benefit most from interventions to increase their PsyCap. This study supports PsyCap as an antecedent to work engagement.

Multiple levels and multiple challenges for measurement, reporting and verification of REDD+

2013-08-01

Full Text Available REDD+ is a multilevel endeavour. Global demands, national and subnational structures and local people’s needs and aspirations must all be linked in efforts to reduce emissions from deforestation and forest degradation. We use Brockhaus and Angelsen’s (2012 framework of Institutions, Interests, Information and Ideas (4Is to analyse the multilevel governance of REDD+ through one of its core elements: measurement, reporting and verification. We present the multilevel dimensions of REDD+ and the risks if they are disregarded. We analyse the flow and interplay of information, institutions and interests across levels in REDD+ measurement, reporting and verification and examine which multilevel governance mechanisms enable this flow. To support our analysis, we provide anecdotal evidence of challenges and opportunities from three countries: Brazil, Vietnam and Indonesia. Our analysis shows that it is essential to enhance and harmonize information flows between local and national levels for measurement, reporting and verification to be accountable. Furthermore, sound information flows between levels can increase the negotiation power of disadvantaged groups and ensure a more effective, efficient and equitable REDD+. To reduce the risk of conflict, REDD+ multilevel governance systems must match incentives and interests with transparent institutions. Effective multilevel governance mechanisms, such as novel cross-scale institutional arrangements, uniform regulations on the rights, responsibilities and procedures for monitoring information flows, and participation across levels, will provide tools for both information flow and greater matching of different interests across levels.

The number of categorical sexually transmitted disease (STD) clinics is declining in the United States. Federally qualified health centers (FQHCs) have the potential to supplement the needed sexually transmitted infection (STI) services. In this study, we describe the spatial distribution of FQHC sites and determine if reported county-level nonviral STI morbidity were associated with having FQHC(s) using spatial regression techniques. We extracted map data from the Health Resources and Services Administration data warehouse on FQHCs (ie, geocoded health care service delivery [HCSD] sites) and extracted county-level data on the reported rates of chlamydia, gonorrhea and, primary and secondary (P&S) syphilis (2008-2012) from surveillance data. A 3-equation seemingly unrelated regression estimation procedure (with a spatial regression specification that controlled for county-level multiyear (2008-2012) demographic and socioeconomic factors) was used to determine the association between reported county-level STI morbidity and HCSD sites. Counties with HCSD sites had higher STI, poverty, unemployment, and violent crime rates than counties with no HCSD sites (P < 0.05). The number of HCSD sites was associated (P < 0.01) with increases in the temporally smoothed rates of chlamydia, gonorrhea, and P&S syphilis, but there was no significant association between the number of HCSD per 100,000 population and reported STI rates. There is a positive association between STI morbidity and the number of HCSD sites; however, this association does not exist when adjusting by population size. Further work may determine the extent to which HCSD sites can meet unmet needs for safety net STI services.

Only 0.0028% of the oil produced in the Gulf of Mexico from 1971 through 1975 was spilled. World-wide, natural seeps introduce nearly 7 times more oil into the sea than offshore activity, while transportation, the worst offender, puts in 25 times more than offshore oil. The report includes data for spills of 50 bbl or less; about 85.5% of the total spill volume was from 5 of the 5857 incidents. In only one case was environmental damage reported, when minor amounts of oil reached 1000 ft of beach on the Chandeleur Islands after the 9/9/74 Cobia pipeline break. The report states that 50 ppm discharges cause no adverse effect, and that hydrocarbons in this concentration may even benefit microbial sea life.

Exceptionally High Creatine Kinase (CK) Levels in Multicausal and Complicated Rhabdomyolysis: A Case Report.

Science.gov (United States)

Luckoor, Pavan; Salehi, Mashal; Kunadu, Afua

2017-07-04

BACKGROUND Rhabdomyolysis is a syndrome caused by muscle breakdown. It can be caused by traumatic as well as non-traumatic factors such as drugs, toxins, and infections. Although it has been initially associated with only traumatic causes, non-traumatic causes now appear to be at least 5 times more frequent. In rhabdomyolysis, the CK levels can range anywhere from 10 000 to 200 000 or even higher. The higher the CK levels, the greater will be the renal damage and associated complications. We present the case of a patient with exceptionally massive rhabdomyolysis with unusually high CK levels (nearly 1 million) caused by combined etiologic factors and complicated with acute renal failure. CASE REPORT A 36-year-old African American male patient with no significant past medical history and a social history of cocaine and alcohol abuse presented with diarrhea and generalized weakness of 2 days' duration. He was found to be febrile, tachycardic, tachypneic, and hypoxic. The patient was subsequently intubated and admitted to the medical ICU. Laboratory work-up showed acute renal failure with deranged liver functions test results, and elevated creatine kinase of 701,400 U/L. CK levels were subsequently too high for the lab to quantify. Urine legionella testing was positive for L. pneumophilia serogroup 1 antigen and urine toxicology was positive for cocaine. The patient had a protracted course in the ICU. He was initially started on CVVH, and later received intermittent hemodialysis for about 1 month. CONCLUSIONS In the presence of multiple etiologic factors, rhabdomyolysis can be massive with resultant significant morbidity. Clinicians should have a high index of suspicion for rhabdomyolysis in the presence of multiple factors, as early recognition of this diseases is very important in the prevention and active management of life-threatening conditions.

Angiogenesis is a multistep process in which many growth factors and cytokines have an essential role. Vascular endothelial growth factor (VEGF) is a potent angiogenic agent that acts as a specific mitogen for vascular endothelial cells through specific cell surface receptors. The interleukin-6 (IL-6) pathway is another mechanism linking angiogenesis to malignancy. C-reactive protein (CRP), a representative marker for inflammation, is known for its association with disease progression in many cancer types. The aim of this study was to determine preoperative serum levels of VEGF, IL-6, and CRP in colorectal carcinoma, and to correlate them with disease status and prognosis. A 132 of 143 patients who underwent curative resection for colorectal cancer were enrolled in this study. 11 patients with resection margin positive were excluded. Factors considered in analysis of the relationship between VEGF, IL-6, and CRP and histological findings. Patient prognosis was investigated. Serum levels of VEGF and IL-6 were assessed using Enzyme-Linked Immuno-Sorbent Assay (ELISA), and CRP was measured using immunoturbidimetry. Median follow-up duration was 18.53 months (range 0.73-43.17 months) and median age of the patients was 62 years (range, 26-83 years). Mean and median levels of VEGF and CRP in colorectal cancer were significantly higher than in the normal control group; 608 vs. 334 pg/mL and 528 (range 122-3242) vs. 312 (range 16-1121) (p < 0.001); 1.05 mg/dL vs. 0.43 mg/dL and 0.22 (range 0.00-18.40) vs. 0.07 (range 0.02-6.94) (p = 0.002), respectively. However mean and median level of IL-6 in patients were not significantly higher than in control; 14.33 pg/mL vs. 5.65 pg/mL and 6.00 (range 1.02-139.17) vs. 5.30 (4.50-13.78) (p = 0.327). Although IL-6 and CRP levels were not correlated with other pathological findings, VEGF level was significantly correlated with tumor size (p = 0.012) and CEA (p = 0.038). When we established the cutoff value for VEGF (825 pg/mL), IL-6 (8

Objective: To investigate the clinical significance of changes of plasma ET, IGF-II, CNP and serum NSE contents in patients with acute brain injury. Methods: Serum contents of neuron specific enolase (NSE) were measured with chemiluminescence immunoassay and plasma endothelin (ET), insulin-like growth factor-II (IGF-II) and C-type natriuretic peptide (CNP) were measured with radioimmunoassay in 30 patients with acute brain injury and 35 controls. Results: Serum contents of NSE and plasma IGF-II, CNP were not much different in patients with mild brain injury from those in controls (P >0.05), but plasma contents of ET were already significantly higher in patients with mild brain injury than those in controls(P < 0.01). The serum NSE and plasma ET levels in patients with moderate and severe brain injury were significantly higher than those in patients with mild brain injury and controls (P < 0.01). Decrease of plasma levels of IGF-II and CNP was not significant in patients with mild brain injury (vs controls). However, the plasma levels of IGF-II and CNP were significantly lower in patients with moderate and severe brain injury than those in patients with mild brain injury and controls (P <0.01). As a whole, the magnitude of changes of these parameters was proportional to the severity of the injury. Conclusion: Changes of serum NSE and plasma IGF-II, ET and CNP levels were closely related to the pathological process of brain injury. Determination of these parameters was of clinical importance for evaluation of the severity of injury and outcome prediction. (authors)

ENVIRONMENTAL REPORTING AT INTERNATIONAL LEVEL (STUDY OF THE LITERATURE

Full Text Available One of the most important areas of development during the last 15 years, as far as accounting is concerned, has been the environmental reporting and accounting, generating interests beyond the restrictions imposed by purely academic discussions or the professional accountants community. The objective of the paper is represented by the analysis of scientific knowledge and existing practices in the area of environmental reporting. Mathews (1997, 2001 and Parker (2005 are one of the most representative studies that examine the evolution and status of researches in the area of accounting and environmental reporting. Because of the fact that reports offered by the traditional financial accounting system are insufficient for reflecting a clear and complete image of the company's environmantal impact, I monitored the frameworks or mechanisms of environmental information. Also, the paper analysis the articles treating international environmental reporting, articles publised in ISI quoted or BDI indexed journals. The collection and analysis of reporting frames, the interpretation and analysis thereof represent the main instruments used in order to bring to the forefront the main existing reporting frames for environmental information, found at international level. The quantitative, applicative research is used to reflect the current status of researches in the field of environmental reporting, using the non-participative observation to reflect the current status of researches in the field of environmental reporting, by using the non-participative observation, the collection and analysis of articles as main research instruments. The study concludes that environmental reporting continues to represent the main attraction of researchers in the field of environmental accounting. The main reason for researches on environmental reporting is represented by the description, investigation and improvement of practices on accounting and reporting environmental

A longstanding critique of project-level environmental assessment is that it is weak at addressing cumulative effects, and because of this many argue that cumulative effects are best managed at a regional scale. However, in the absence of regional management it is important that project-level assessment supports cumulative effects management as best as possible. In this paper we present case study socio-economic impact assessments of liquefied natural gas development on Aboriginal groups on Canada's west coast. The case studies use an analytical structure modified from typical Canadian practice including unambiguous and non-arbitrary significance thresholds grounded in stakeholder values to focus baselines, impact assessment, and significance determination on cumulative effects. This approach is found to be more capable of informing decision-makers on cumulative effects as well as more rigorous and transparent than typical assessments. Much of this approach is not conceptually new, but at least in western Canada such an approach is not typically used or meaningfully implemented by practitioners. As such, the case studies serve to illustrate how practice can bolster project-level assessment. - Highlights: •Typical project assessment is weak with respect to cumulative effects. •Modified analysis structure and thresholds enable a focus on cumulative effects. •Clear, value-based thresholds make analysis rigorous, transparent, and democratic.

2000-04-21

The objective of this work is to evaluate unqualified, water-level data gathered under the Nye County Early Warning Drilling Program (EWDP) and to determine whether the status of the data should be changed to ''qualified'' data in accordance with AP-SIII.2Q (Qualification of Unqualified Data and the Documentation of Rationale for Accepted Data). The corroboration method (as defined in Attachment 2 of AP-SIII.2Q) was implemented to qualify water-level data from Nye County measurements obtained directly from the Nye County Nuclear Waste Repository Program Office (NWRPO). Comparison of United States Geological Survey (USGS) measurements contained in DTN GS990608312312.003 with the Nye County water-level data has shown that the differences in water-level altitudes for the same wells are significantly less than 1 meter. This is an acceptable finding. Evaluation and recommendation criteria have been strictly applied to qualify Nye County measurements of water levels in selected wells measured by the USGS. However, the process of qualifying measured results by corroboration also builds confidence that the Nye County method for measurement of water levels is adequate for the intended use of the data (which is regional modeling). Therefore, it is reasonable to extend the term of ''qualified'' to water-level measurements in the remaining Nye County Phase I wells on the basis that the method has been shown to produce adequate results for the intended purpose of supporting large-scale modeling activities for the Yucca Mountain Project (YMP). The Data Qualification Team recommends the Nye County, water-level data contained in Appendix D of this report be designated as ''qualified''. These data document manual measurements of water-levels in eight (8) EWDP Phase I drillholes that were obtained prior to the field installation of continuous monitoring equipment.

The objective of this work is to evaluate unqualified, water-level data gathered under the Nye County Early Warning Drilling Program (EWDP) and to determine whether the status of the data should be changed to ''qualified'' data in accordance with AP-SIII.2Q (Qualification of Unqualified Data and the Documentation of Rationale for Accepted Data). The corroboration method (as defined in Attachment 2 of AP-SIII.2Q) was implemented to qualify water-level data from Nye County measurements obtained directly from the Nye County Nuclear Waste Repository Program Office (NWRPO). Comparison of United States Geological Survey (USGS) measurements contained in DTN GS990608312312.003 with the Nye County water-level data has shown that the differences in water-level altitudes for the same wells are significantly less than 1 meter. This is an acceptable finding. Evaluation and recommendation criteria have been strictly applied to qualify Nye County measurements of water levels in selected wells measured by the USGS. However, the process of qualifying measured results by corroboration also builds confidence that the Nye County method for measurement of water levels is adequate for the intended use of the data (which is regional modeling). Therefore, it is reasonable to extend the term of ''qualified'' to water-level measurements in the remaining Nye County Phase I wells on the basis that the method has been shown to produce adequate results for the intended purpose of supporting large-scale modeling activities for the Yucca Mountain Project (YMP). The Data Qualification Team recommends the Nye County, water-level data contained in Appendix D of this report be designated as ''qualified''. These data document manual measurements of water-levels in eight (8) EWDP Phase I drillholes that were obtained prior to the field installation of continuous monitoring equipment

This test report documents the results obtained while conducting operational testing of a new TK 102 level controller and total outflow integrator added to the NHCON software that controls the Low-Level Wastewater Treatment Facility (LLWTF). The test was performed with WHC-SD-CP-OTP 154, PFP Low-Level Wastewater Treatment Facility Process Control Operational Test. A complete test copy is included in appendix A. The new TK 102 level controller provides a signal, hereafter referred to its cascade mode, to the treatment train flow controller which enables the water treatment process to run for long periods without continuous operator monitoring. The test successfully demonstrated the functionality of the new controller under standard and abnormal conditions expected from the LLWTF operation. In addition, a flow totalizer is now displayed on the LLWTF outlet MICON screen which tallies the process output in gallons. This feature substantially improves the ability to retrieve daily process volumes for maintaining accurate material balances

Full Text Available This research aims to compare the perceptions of intermediate and mid-level accounting professional candidates on accounting and financial reporting standards. A significant part of accounting process is carried out by vocational school graduate intermediate and mid-level accounting professionals. However, it can be claimed that adequate education about accounting and financial reporting standards isn’t given in vocational schools although these standards structure the whole accounting process. A survey is conducted over students of the related vocational school in Aksaray University. The results indicate no significant difference on students’ perceptions in terms of their school year, high school type, job or internship experience and intention to perform the profession after graduation. These results can be traced to inadequacy of present curriculums and internship programs which can’t create a difference. Based on the results, the content of internship applications is rearranged and an optional subject named as “Accounting and Reporting Standards” is established.

Herting, D.L.; Lunsford, T.R.

1994-01-01

The objective of this technology task plan is to develop and demonstrate a scaleable process of reclaim sodium nitrate (NaNO 3 ) from Hanford waste tanks as a clean nonradioactive salt. The purpose of the so-called Clean Salt Process is to reduce the volume of low level waste glass by as much as 70%. During the reporting period of October 1, 1993, through May 31, 1994, progress was made on four fronts -- laboratory studies, surrogate waste compositions, contracting for university research, and flowsheet development and modeling. In the laboratory, experiments with simulated waste were done to explore the effects of crystallization parameters on the size and crystal habit of product NaNO 3 crystals. Data were obtained to allows prediction of decontamination factor as a function of solid/liquid separation parameters. Experiments with actual waste from tank 101-SY were done to determine the extent of contaminant occlusions in NaNO 3 crystals. In preparation for defining surrogate waste compositions, single shell tanks were categorized according to the weight percent NaNO 3 in each tank. A detailed process flowsheet and computer model were created using the ASPENPlus steady state process simulator. This is the same program being used by the Tank Waste Remediation System (TWRS) program for their waste pretreatment and disposal projections. Therefore, evaluations can be made of the effect of the Clean Salt Process on the low level waste volume and composition resulting from the TWRS baseline flowsheet. Calculations, using the same assumptions as used for the TWRS baseline where applicable indicate that the number of low level glass vaults would be reduced from 44 to 16 if the Clean Salt Process were incorporated into the baseline flowsheet

BEIR-III report and the health effects of low-level radiation

Fabrikant, J.I.

The present BEIR-III Committee has not highlighted any controversy over the health effects of low-level radiation. In its evaluation of the experimental data and epidemiological surveys, the Committee has carefully reviewed and assessed the value of all the available scientific evidence for estimating numerical risk coefficients for the health hazards to human populations exposed to low levels of ionizing radiation. Responsible public awareness of the possible health effects of ionizing radiations from medical and industrial radiation exposure, centers on three important matters of societal concern: (1) to place into perspective the extent of harm to the health of man and his descendants to be expected in the present and in the future from those societal activities involving ionizing radiation; (2) to develop quantitative indices of harm based on dose-effect relationships; such indices could then be used with prudent caution to introduce concepts of the regulation of population doses on the basis of somatic and genetic risks; and (3) to identify the magnitude and extent of radiation activities which could cause harm, to assess their relative significance, and to provide a framework for recommendations on how to reduce unnecessary radiation exposure to human populations. The main difference of the BEIR Committee Report is not so much from new data or new interpretations of existing data, but rather from a philosophical approach and appraisal of existing and future radiation protection resulting from an atmosphere of constantly changing societal conditions and public attitudes

Full Text Available As a developing country that accumulates its source of revenue to taxes, Indonesia is not spared from tax compliance issues. The low level of tax compliance indicates a different point of view between the government and the Taxpayer. The low level of tax compliance indicates a different point of view between the government and the Taxpayer. Taxpayers still consider the obligation to pay taxes as an expense that can reduce their income or profits. Therefore, the rational Taxpayer will try to minimize the tax burden. One of them is by doing Tax Evasion. Taxation management is more often done by the Taxpayer Agency, especially the Manufacturing company. This is because the company has a very high business risk. Tax Evasion can increase organizational complexity which in turn can reduce financial transparency. Therefore, companies are required to disclose more information and provide flexible reporting systems that facilitate stakeholders. This encourages companies in the world to take advantage of the development of information technology and interconnection networking through internet corporate reporting. Utilization of internet corporate reporting is expected to increase the value of the company. This study aims to analyze the relationship between the concept of Tax Evasion, the level of internet corporate reporting disclosure, and the firm value. The results showed that the three hypotheses in this study were accepted. Tax Evasion affects the level of internet corporate reporting disclosure. In addition, Tax Evasion also directly or indirectly influence the firm value through the level disclosure of internet corporate reporting.

Significantly Elevated Serum Lipase in Pregnancy with Nausea and Vomiting: Acute Pancreatitis or Hyperemesis Gravidarum?

2015-01-01

Full Text Available Hyperemesis gravidarum is a severe manifestation of nausea and vomiting of pregnancy and it is associated with weight loss and metabolic abnormalities. It is known that abnormal laboratory values, including mildly elevated serum lipase level, could be associated with hyperemesis gravidarum. However, in this case report details of two women with hyperemesis gravidarum but with significantly elevated serum lipase levels were discussed. These patients presented with severe nausea and vomiting but without abdominal pain. They were found to have severely elevated lipase levels over 1,000 units/liter. In the absence of other findings of pancreatitis, they were treated with conservative measures for hyperemesis gravidarum, with eventual resolution to normal lipase levels. Although significantly elevated lipase level in pregnant patients with nausea and vomiting is a concern for acute pancreatitis, these two cases of significantly elevated serum lipase without other clinical findings of pancreatitis led to this report that serum lipase could be quite elevated in hyperemesis gravidarum and that it might not be an accurate biochemical marker for acute pancreatitis. Imaging studies are thus necessary to establish the diagnosis of acute pancreatitis.

International Nuclear Information System (INIS)

1985-09-01

This report documents the initial conceptual design studies for a repository sealing system for a high-level nuclear waste repository in salt. The first step in the initial design studies was to review the current design level, termed schematic designs. This review identified practicality of construction and development of a design methodology as two key issues for the conceptual design. These two issues were then investigated during the initial design studies for seal system materials, seal placement, backfill emplacement, and a testing and monitoring plan. The results of these studies have been used to develop a program plan for completion of the sealing system conceptual design. 60 refs., 26 figs., 18 tabs

Castagnacci, A.; Dalton, D.; Genoa, P.

1994-11-01

Since 1989, the nuclear industry has been moving in the direction of greater minimization of low level radioactive waste (LLW). This has been driven in part by increasing regulatory attention, but it also is in response to the desire on the part of nuclear utilities to be more cost efficient and to be environmentally responsive. Over the past half-dozen years, LLW disposal costs have increased dramatically. In addition, improvements in LLW volume reduction technologies have substantially reduced the volume of LLW that is disposed. At the same time, utilities are implementing aggressive source reduction programs and programs to reuse materials so as to extend the useful life of many materials. Thus, there has been a dramatic change in LLW economics and LLW management practices in just the past few years. This report was developed by utility nuclear experts to provide guidance to all utilities on mechanisms for integrating the program economics, advanced volume reduction techniques, and approaches to source reduction. Thus, utilizes will be able to use this report as a guide to optimizing their LLW program economics and minimizing LLW disposal volumes to the smallest reasonable fraction. This report discusses the implementation of these guidelines, management support, waste materials and waste inventory, radioactive tool and equipment management, protective clothing management, processing and volume reduction, solid LLW tracking, outage LLW management, and interim storage of LLW

Objective: To study the clinical significance of changes serum CA153, CA125 and TSGF levels after operation in patients with breast cancer. Methods: Serum CA153, CA125 and TSGF (with RIA) and serum TSGF levels (with biochemistry method) were measured in 36 patients with breast cancer both before and after operation as well as in 35 controls. Results: Before operation, serum levels of serum CA153, CA125 and TSGF in the patients were significantly higher than those in the controls (P < 0.01 ). One month after operation, all the levels were approaching normal. Six months later, the levels in the patients without recurrence remained normal, however, the levels in the 4 patients with recurrence returned to those before operation again. Conclusion: Changes of serum CA153, CA125 and TSGF levels are closely related to the tumor burden and if levels were high after operation, may indicate the presence of recurrence. (authors)

Full Text Available BRAFV600E is the most common mutation in papillary thyroid carcinoma (PTC, and it is associated with high-risk prognostic factors. However, the significance of the BRAF mRNA level in PTC remains unknown. We evaluated the significance of BRAF mRNA expression level by analyzing PTC data from The Cancer Genome Atlas (TCGA database.Data from 499 patients were downloaded from the TCGA database. After excluding other PTC variants, we selected 353 cases of classic PTC, including 193 cases with BRAFV600E and 160 cases with the wild-type BRAF. mRNA abundances were measured using RNA-Seq with the Expectation Maximization algorithm.The mean BRAF mRNA level was significantly higher in BRAFV600E patients than in patients with wild-type BRAF (197.6 vs. 179.3, p = 0.031. In wild-type BRAF patients, the mean BRAF mRNA level was higher in cases with a tumor > 2 cm than those with a tumor ≤ 2.0 cm (189.4 vs. 163.8, p = 0.046, and was also higher in cases with lymph node metastasis than in those without lymph node metastasis (188.5 vs. 157.9, p = 0.040. Within BRAFV600E patients, higher BRAF mRNA expression was associated with extrathyroidal extension (186.4 vs. 216.4, p = 0.001 and higher T stage (188.1 vs. 210.2, p = 0.016.A higher BRAF mRNA expression level was associated with tumor aggressiveness in classic PTC regardless of BRAF mutational status. Evaluation of BRAF mRNA level may be helpful in prognostic risk stratification of PTC.

Objective: To investigate the dynamic changes of serum insulin-like growth factor-1 (IGF-1) levels in patients with acute cerebrovascular accident. Methods: Serum IGF-1 levels were determined with RIA in 40 patients with cerebral infarction, 20 patients with lacunar infarcts and 40 patients with cerebral haemorrhage within 3days after onset and on d14 as well as in 30 controls. Results: The serum IGF-1 levels in patients with cerebral vascular accidents were significantly lower than those in controls (P 0.05). Conclusion: Serum levels of IGF-1 dropped markedly during the acute stage after cerebrovascular accident and the magnitude might reflect the severity of the event, IGF-1 might be capable of crossing the blood-brain barrier after cerebrovascular accident and providing some protection against nerve injury, this fact might be of potential clinical applicability.

Objective: To investigate the effects of radiotherapy on the level of lysophosphatidic acid (LPA) in different patients. Methods: Three groups of patients (metastatic brain tumor group, non-brain tumor group and primary brain tumor group) were given external irradiation (by linear accelerator). LPA level, white blood cell count and platelet count in the blood plasma were evaluated pre-irradiation and after irradiation with 40 Gy and 60 Gy respectively. Results: The LPA level decreased gradually as irradiation doses increase in metastatic brain tumor group non-brain tumor group (after irradiation with 60 Gy 0.05), and neoplasm volume changed little. White blood cell count and platelet count gradually decreased with the increasing irradiation doses in metastatic brain tumor group and primary brain tumor group, but there was no significant correlation to LPA level. However, there was a negative correlation to LPA level in non-brain tumor group (r=-0.285 and r=-0.237, both P<0.05 ). Conclusions: There is a negative correlation between radiotherapy dose and LPA level in metastatic brain tumor patients and non-brain tumor patients. LPA level could be used as a predictor of the effect of the radiotherapy in tumor treatment. (authors)

The study aimed at evaluating the effect of elevated serum insulin-like growth factor-1( IGF-1), which is a by-product of growth hormone in the body on glycemic control (assessed by measuring HbA1c) and lipid profiles in adolescent patients (aged between 12 and 18 years) suffering from diabetes mellitus Type 1 (childhood onset diabetes mellitus ). Thirty patients with diabetes mellitus type one were enrolled in the study within the age range mentioned (mean age was 15.2 ± 3). These patients had high-normal IGF-1 levels according to the normal standard range for their age group). A second group of thirty patients with diabetes mellitus type 1 with normal IGF-1 levels (mean age was 14.6 ± 2.5) were also enrolled for this study. A third group included thirty age and sex matched healthy controls. HbA1-c was measured in all of the patients involved in the study as well as serum IGF-1. Lipid profiles were as sassed and they included total cholesterol, low density lipoproteins (LDL) High density lipoproteins (HDL) and serum triglycerides. A significant elevation in HbA1c levels was observed in diabetes mellitus type 1 patients with normal levels of IGF-1 as compared to patients with diabetes mellitus type 1 with high normal IGF-1 levels or normal control subjects (mean HbA1c levels for group 2 as compared to groups 1 and 3 were 9.20 ±0.64 vs. 7.01 ±0.56 vs. 5.11 ±0.57 respectively, p<0.01). A significant negative correlation was established between serum IGF levels and HbA1c (r= - 0.46, p=0.0 2). These results required the reassessment of management protocols for patients be longing to Group 2. Serum total cholesterol levels, LDL-C, and triglycerides were significantly higher in the second group as compared to the other groups while HDL levels in the same group were found to be significantly lower. A significant negative correlation was established between serum LDL-C levels and IGF- levels measured in all participants (r= - 0.41, p=0.02). This study concluded that

Subclinical hyperthyroidism is an increasingly recognized entity that is defined as a normal serum free thyroxine and free triiodothyronine levels with a thyroid-stimulating hormone level suppressed below the normal range and usually undetectable. It has been reported that sub-clinical hyperthyroidism is not associated with CHD or mortality from cardiovascular causes but is sufficient to induce arrhythmias including atrial fibrillation and atrial flutter. Moreover increased factor X activity in patients with subclinical hyperthyroidism represents a potential hypercoagulable state. It has been also reported an acute myocardial infarction with normal coronary arteries associated with iatrogenic hyperthyroidism and with a myocardial bridge too. It has been also reported an acute myocardial infarction without significant coronary stenoses associated with subclinical hyperthyroidism. Furthermore it has been reported that at highly increased hematocrit levels patients may experience hyperviscosity symptoms. We present a case of atrial fibrillation and acute myocardial infarction without significant coronary stenoses associated with subclinical hyperthyroidism and erythrocytosis. Also this case focuses attention on the importance of a correct evaluation of subclinical hyperthyroidism. Copyright © 2008 Elsevier Ireland Ltd. All rights reserved.

Objective: To study the relationship between changes of plasma levels of adrenomedullin(AM), calcitonin-gene-related peptide(CGRP), soluble intercellular adhesion molecule-1(sICAM-1), total homocysteine(THcy) and the progression of disease in patients with PIH. Methods: Plasma AM, CGRP(with RIA), sICAM-1(with ELISA) and THcy(with CLIA) levels were measured in 1)35 non-pregnant women 2) 35 normal pregnant women and 3) 35 women with PIH(both before and after two weeks' treatment). Results: The plasma AM levels in normal pregnant women were insignificantly higher than those in non-pregnant women (P>0.05). The plasma AM levels in patients with PIH before treatment were significantly higher than those in normal pregnant women (P 0.05). Both plasma sICAM-1 and THcy levels in normal pregnant women were insignificantly higher than those in non-pregnant women. The levels were significantly higher in patients with PIH before treatment than those in normal pregnant women and became only insignificantly higher after treatment. Conclusion: Changes of plasma levels of AM, CGRP, sICAM-1 and THcy were closely related to the disease process in patients with PIH. (authors)

Objective: To detect the changes of serum NSE, SIL-2R and TNF levels in the 33 patients with lung cancer undergoing chemotherapy. Methods: Serum NSE, SIL-2R and TNF levels were determined with RIA and SIL-2R levels with ELISA in 33 lung cancer patients both before and after chemotherapy (n=28) as well as in 30 controls. Results: Before chemotherapy, serum NSE, SIL-2R and TNF levels in the patients were significantly higher than those in the controls (P<0.01). After chemotherapy, in 20 cases without recurrence at 6 months, the levels were much lower but still significantly higher than those in controls (P < 0.05 ). However, in the 8 patients with recurrence, the levels increased again to approaching those before chemotherapy. Conclusion: Serum levels of NSE, SIL-2R and TNF might be useful for diagnosis and predicting therapeutic effects after chemotherapy in patients with lung cancer. (authors)

To explore the clinical significance the serum levels of N-Terminal proB-Type natriuretic peptide (NT-proBNP) and high-sensitivity C-reactive protein (hs-CRP) in patients with acute coronary syndrome,the serum levels of NT-proBNP and hs-CRP in patients and normal controls were determined by ECi Immunity Analyzer and radioimmunoassay respectively. The results showed that the serum levels of NT-proBNP and hs-CRP in patients with acute coronary syndrome were significantly higher than that of controls (P<0.05). The diagnostic specificity for acute coronary syndrome was 100% by combined detection of NT-proBNP and hs-CRP. The results suggest that the combined detection of serum NT-proBNP and hs-CRP levels are very important to evaluate heart function in patients with acute coronary syndrome. (authors)

Reporting of clinically significant events represents an important mechanism by which patient safety problems may be identified and corrected. However, time pressure and cumbersome report entry procedures have discouraged the full participation of physicians. To improve the process, our internal medicine training program developed an easy-to-use mobile platform that combines the reporting process with patient sign-out. Between August 25, 2011, and January 25, 2012, our trainees entered clinically significant events into i-touch/i-phone/i-pad based devices functioning in wireless-synchrony with our desktop application. Events were collected into daily reports that were sent from the handoff system to program leaders and attending physicians to plan for rounds and to correct safety problems. Using the mobile module, residents entered 31 reportable events per month versus the 12 events per month that were reported via desktop during a previous 6-month study period. Advances in information technology now permit clinically significant events that take place during "off hours" to be identified and reported (via handoff) to next providers and to supervisors via collated reports. This information permits hospital leaders to correct safety issues quickly and effectively, while attending physicians are able to use information gleaned from the reports to optimize rounding plans and to provide additional oversight of trainee on call patient management decisions.

Quantifying and reporting greenhouse gas emissions at local level

Directory of Open Access Journals (Sweden)

2017-01-01

Full Text Available Cities as global centers of consumption and production often are a significant and growing source of greenhouse gas (GHG emissions. At the same time, local authorities are increasingly taking action on climate change by focusing on reducing GHG emissions and efficiency improvement opportunities. To assess and reduce the overall greenhouse gas emission level from an urban area, it is necessary to identify all the activities and processes which generate these emissions. GHG inventory gives an opportunity to get wider knowledge for city’s community about spatial emission processes and emissions contribution of key sources categories at the local scale. Inventory is being used for decision-making purposes and strategic planning in emission reduction policy. The goal of this paper was to clarify the major methodological challenges of GHG monitoring at the urban level. The paper is based on the discussion of different methods and approaches to assessing GHG emissions at the local level. It is presented sectoral GHGs emission trends in selected urban areas and compared CO2 emission level in different countries and metropolises and variable European cities guidance. The study determines the inventory tools of GHGs emission taking into account the characteristics of main sources at local levels.

The skin microbiome varies across individuals. The causes of these variations are inadequately understood. We tested the hypothesis that inter-individual variation in facial skin microbiome can be significantly explained by variation in sebum and hydration levels in specific facial regions of humans. We measured sebum and hydration from forehead and cheek regions of healthy female volunteers (n = 30). Metagenomic DNA from skin swabs were sequenced for V3-V5 regions of 16S rRNA gene. Altogether, 34 phyla were identified; predominantly Actinobacteria (66.3%), Firmicutes (17.7%), Proteobacteria (13.1%) and Bacteroidetes (1.4%). About 1000 genera were identified; predominantly Propionibacterium (58.6%), Staphylococcus (8.6%), Streptococcus (4.0%), Corynebacterium (3.6%) and Paracoccus (3.3%). A subset (n = 24) of individuals were sampled two months later. Stepwise multiple regression analysis showed that cheek sebum level was the most significant predictor of microbiome composition and diversity followed by forehead hydration level; forehead sebum and cheek hydration levels were not. With increase in cheek sebum, the prevalence of Actinobacteria (p = 0.001)/Propionibacterium (p = 0.002) increased, whereas microbiome diversity decreased (Shannon Index, p = 0.032); this was opposite for other phyla/genera. These trends were reversed for forehead hydration levels. Therefore, the nature and diversity of facial skin microbiome is jointly determined by site-specific lipid and water levels in the stratum corneum.

Objective: To explore the relationship between rheumatoid activity and serum levels of the cytokines interleukin-2 (IL-2), soluble interleukin-2 receptor (sIL-2R), hyaluronic acid (HA), vascular endothelial growth factor (VEGF) in patients with rheumatoid arthritis. Methods: Serum IL-2, HA(with RIA) and sIL-2R, VEGF (with ELISA) levels were determined in 30 controls, 30 patients with active rheumatoid arthritis and 30 patients with rheumatoid arthritis in remission. Sensitivity and specificity for each marker were analyzed. Results: In patients with active rheumatoid arthritis, the serum levels of sIL-2R, HA, VEGF were significantly higher and serum levels of IL-2 significantly lower than those in patients in remission and controls (p<0.01). Determination of VEGF levels possessed the highest specificity (93.3%) and also a high sensitivity (93.3% as well). Conclusion: Determination of the serum levels of any of these markers was valuable for monitoring the activity of the rheumatoid process. It is more desirable to take measurements of VEGF levels due to its highest specificity

This report is the third in a series concerned with the annual genetically significant dose to the population of Great Britain from diagnostic radiology. It combines information from a frequency survey of diagnostic radiological examinations carried out in Great Britain in 1977 and estimates of gonadal doses for different examination types, together with population and child expectancy data. The annual genetically significant dose from diagnostic radiology carried out in Great Britain in 1977, is estimated to 118 μGy (11.8 millirad) of which 113 μGy (11.3 millirad) is contributed by diagnostic radiology carried out in National Health Service hospitals. There has been a sharp fall in the contribution from obstetric examinations since 1957 when the last national survey was carried out. The contribution from most other examination types is broadly similar and there is little evidence of a change in the overall level of genetically significant dose. This is in spite of an increase in the frequency of radiological examinations per thousand of the population of about 50 per cent. No significant differences were found as between England, Scotland and Wales. The British figure compares favourably with the levels of GSD reported from other countries with developed radiological services. (author)

Objective: To study the significance of changes of serum IL-8, IL-1β and TNF-α levels after treatment in patients with chronic prostatitis. Methods: Serum TNF-α (with RIA). IL-8, IL-1β(with ELISA) levels were determined in 40 patients with chronic prostatitis both before and after treatment as well as 35 controls. Results: Before treatment, the serum IL-8, IL-1β and TNF-α levels in the patients were significantly higher than those in controls (P<0.01). After 2 weeks treatment, the IL-8 and IL-1β levels dropped markedly, but remained significantly higher than those in controls (P<0.05). However,the serum TNF-α levels dropped more and were not much different from those in controls (P<0.05). Conclusion: IL-8, IL-1β and TNF-α could take part in the pathogenesis in chronic prostatitis in various ways and determination of these levels clinically important. (authors)

Objective: To investigate the clinical significance of changes of plasma levels of nitricoxide(NO), endothelin (ET) and atrial natriuretic peptide (ANP) before and after hemodialysis in lupus nephritis(LN) patients with renal failure. Methods: Plasma NO (with biochemistry) and ET, ANP(with RIA) levels were measured in 32 lupus patients with renal failure both before and after a course of hemodialysis and 32 controls. Results: The plasma levels of NO, ET and ANP in the 32 LN patients with renal failure were significant higher than those in controls (P<0.05) before hemodialysis, the NO, ET and ANP levels were positively correlated with the BUN and creatinine levels. After a course of hemodialysis, plasma NO and ANP decreased significantly (P<0.05), but no significant changes were observed in plasma ET levels. Conclusion: The plasma level of NO, ET and ANP could help to assess the damage of renal function and hemodialysis could lower the level of NO and ANP in LN patients with renal failure. (authors)

Assessment of human health risk of reported soil levels of metals and radionuclides in Port Hope

International Nuclear Information System (INIS)

1991-11-01

Risk assessment methods are applied to the question of health implications of contaminated soil in the Port Hope area. Soil-related as well as other pathways of exposure are considered. Exposures to the reported levels of uranium, antimony, chromium, copper, nickel, cadmium, cobalt, selenium, and zinc in Port Hope soils are not expected to result in adverse health consequences. Oral exposure to arsenic in soil at the reported levels is estimated to result in incremental cancer risk levels in the negligible range (10 -5 ). Estimated exposures also fall well below suggested toxic thresholds for arsenic. For the two small areas within the >50 μg/g isopleth, assessment of exposure is difficult without more definitive data on soil concentrations in these zones. Contamination of soils with lead is overall quite limited. In general, the reported soil levels of lead are not anticipated to pose a hazard. The site with the highest concentrations of lead is located on the west bank of the Ganaraska River, a popular fishing area. Depending on the level and extent of contamination, as well as degree of contact with the site, potential exposures could exceed tolerable intakes for children. Exposures to the radionuclides Ra(226), Pb(210), and U(238) in soil at the reported levels are estimated to fall well within recommended population limits

International Nuclear Information System (INIS)

2001-08-01

On 18 February 2000 the Health and Safety Executive (HSE) published a report on the work of its Nuclear Installations Inspectorate (NIl) in regulating the storage of liquid high level waste at the BNFL Sellafield site. Within the report NIl gave two undertakings. One was to publish an addendum around 1 year later covering its assessment of the new safety case for the storage plant and the second was to publish a further addendum when progress had been made with options studies for reducing the stocks of liquid high level waste (HLW), also referred to as highly active liquor (HAL), to a buffer level. A progress report was published in February 2001 which included a summary of the assessment of the new safety case and NIl's regulatory action to enforce liquid HLW stock reductions. This addendum provides a more detailed update on the position reached based on consideration of BNFL's responses to the recommendations from the February 2000 HLW report since its publication. It embodies the two addenda referred to above integrated into a single document for publication

Cytokeratin 18 (CK18), a type I cytokeratin of the intermediate filament family, has been associated with the prognosis of cancer patients for decades. However, its exact role in predicting the clinical outcome of breast cancer remains controversial. To comprehensively investigated the prognostic value of CK18 in breast cancer, a systematically meta-analysis was conducted to explore the association between CK18 expression and overall survival. Literature collection was conducted by retrieving electronic databases Pubmed, Cochrane Library, Web of Science, EMBASE, and OVID completely (up to January 1, 2017). Nine relevant studies with 4857 cases assessing the relationship between CK18 high expression and the outcome of breast cancer patients were enrolled in our analysis. The results indicated that the high level of CK18 expression was significantly associated with overall survival of breast cancer patients via a specimen-depended manner. Reports which used serum to detect the expression of CK18 predicted a poor outcome of breast cancer (HR = 1.24, 95%CI: 1.11-1.38, P present study demonstrated that CK18 might be served as a novel biomarker to predict clinicopathological features and the outcome of breast cancer. © 2018 The Author(s).

2005-01-01

Objective: To study the changes of serum IL-2, SIL-2R and TNF-α levels after chemotherapy in 34 patients with ovary cancer. Methods: Serum IL-2, TNF-α (with RIA) and SIL-2R (with ELISA) levels were measured in 34 patients with ovary cancers both before and 6 months after chemotherapy as well as in 30 controls. Results: Before chemotherapy in the patients the serum IL-2 levels were significantly lower and serum SIL-2R and TNF-α levels were significantly higher than those in the controls (P<0.01). Six months after chemotherapy, those patients without recurrence (n=21) had their IL-2, SIL-2R and TNF-α levels returned to normal, but in those with recurrences (n=10) the levels were about the same as before. Conclusion: Serum IL-2, SIL-2R and TNF-α levels changes could reflect the immunostatus of the patients as well as the progress of diseases and could be of prognostic value. (authors)

Ghaly, Maurice; Teplitz, Dale

Diurnal cortisol secretion levels were measured and circadian cortisol profiles were evaluated in a pilot study conducted to test the hypothesis that grounding the human body to earth during sleep will result in quantifiable changes in cortisol. It was also hypothesized that grounding the human body would result in changes in sleep, pain, and stress (anxiety, depression, irritability), as measured by subjective reporting. Twelve (12) subjects with complaints of sleep dysfunction, pain, and stress were grounded to earth during sleep for 8 weeks in their own beds using a conductive mattress pad. Saliva tests were administered to establish pregrounding baseline cortisol levels. Levels were obtained at 4-hour intervals for a 24-hour period to determine the circadian cortisol profile. Cortisol testing was repeated at week 6. Subjective symptoms of sleep dysfunction, pain, and stress were reported daily throughout the 8-week test period. Measurable improvements in diurnal cortisol profiles were observed, with cortisol levels significantly reduced during night-time sleep. Subjects' 24-hour circadian cortisol profiles showed a trend toward normalization. Subjectively reported symptoms, including sleep dysfunction, pain, and stress, were reduced or eliminated in nearly all subjects. Results indicate that grounding the human body to earth ("earthing") during sleep reduces night-time levels of cortisol and resynchronizes cortisol hormone secretion more in alignment with the natural 24-hour circadian rhythm profile. Changes were most apparent in females. Furthermore, subjective reporting indicates that grounding the human body to earth during sleep improves sleep and reduces pain and stress.

Significant Traumatic Intracranial Hemorrhage in the Setting of Massive Bee Venom-Induced Coagulopathy: A Case Report.

Science.gov (United States)

Stack, Kelsey; Pryor, Lindsey

2016-09-01

Bees and wasps of the Hymenoptera order are encountered on a daily basis throughout the world. Some encounters prove harmless, while others can have significant morbidity and mortality. Hymenoptera venom is thought to contain an enzyme that can cleave phospholipids and cause significant coagulation abnormalities. This toxin and others can lead to reactions ranging from local inflammation to anaphylaxis. We report a single case of a previously healthy man who presented to the emergency department with altered mental status and anaphylaxis after a massive honeybee envenomation that caused a fall from standing resulting in significant head injury. He was found to have significant coagulopathy and subdural bleeding that progressed to near brain herniation requiring emergent decompression. Trauma can easily occur to individuals escaping swarms of hymenoptera. Closer attention must be paid to potential bleeding sources in these patients and in patients with massive bee envenomation.

It is controversial whether the surgical restoration of sagittal balance and spinopelvic angulation in a single level lumbar degenerative spondylolisthesis results in clinical improvements. The purpose of this study to systematically review the available literature to determine whether the surgical correction of malalignment in lumbar degenerative spondylolisthesis correlates with improvements in patient-reported clinical outcomes. Literature searches were performed via Ovid Medline, Embase, CENTRAL and Web of Science using search terms "lumbar," "degenerative/spondylolisthesis" and "surgery/surgical/surgeries/fusion". This resulted in 844 articles and after reviewing the abstracts and full-texts, 13 articles were included for summary and final analysis. There were two Level II articles, four Level III articles and five Level IV articles. Most commonly used patient-reported outcome measures (PROMs) were Oswestery disability index (ODI) and visual analogue scale (VAS). Four articles were included for the final statistical analysis. There was no statistically significant difference between the patient groups who achieved successful surgical correction of malalignment and those who did not for either ODI (mean difference -0.94, CI -8.89-7.00) or VAS (mean difference 1.57, CI -3.16-6.30). Two studies assessed the efficacy of manual reduction of lumbar degenerative spondylolisthesis and their clinical outcomes after the operation, and there was no statistically significant improvement. Overall, the restoration of focal lumbar lordosis and restoration of sagittal balance for single-level lumbar degenerative spondylolisthesis does not seem to yield clinical improvements but well-powered studies on this specific topic is lacking in the current literature. Future well-powered studies are needed for a more definitive conclusion. Copyright © 2017 Elsevier Ltd. All rights reserved.

1986-04-01

The report presents data gathered during radiological monitoring program conducted in the environs of the Browns Ferry Nuclear Plant. Dose estimates were made from concentrations of radioactivity found in samples of media including air, milk, food products, drinking water, and fish. Inhalation and ingestion doses estimated for persons at the indicator locations were essentially identical to those determined for persons at control locations. Greater than 95% of those doses were contributed by the naturally occurring K-40 and by Sr-90 and Cs-137 which are long-lived radioisotopes found in fallout from nuclear weapons testing. Increased levels of I-131 were reported in air, milk, and rainwater following the accident at the Chernobyl nuclear power station. In addition, Ru-103, Cs-137, and Cs-134 were identified in air particulates, and traces of Ru-103 were found in rainwater

The cytoskeleton regulatory protein Mena is reportedly overexpressed in breast cancer; however, data regarding its expression level and clinical significance in gastric carcinoma (GC) is limited. The aim of the present study was to investigate Mena expression levels and prognostic significance in GC. Mena mRNA expression level was determined by reverse transcription-quantitative polymerase chain reaction in 10 paired GC and adjacent normal tissues. The Mena protein expression level was analyzed in paraffin-embedded GC samples and adjacent normal tissues by immunohistochemistry. Statistical analyses were also performed to evaluate the clinicopathological significance of Mena. The results revealed that the mRNA expression level of Mena was significantly higher in G Ct issues compared with in adjacent normal tissues from10 paired samples. In the paraffin-embedded tissue samples, the protein expression level of Mena was higher in G Ct issues compared with in adjacent normal tissues. Compared with adjacent normal tissues, Mena overexpression was observed in 52.83% (56/106) of patients. The overexpression of Mena was significantly associated with the T stage (P=0.033), tumor-node-metastasis (TNM) stage (PMena expression level was an independent prognostic factor for overall survival time. In conclusion, Mena wasoverexpressed in G C tissues and significantly associated with the T stage, TNM stage and overall survival time. Mena may therefore be suitable as a prognostic indicator for patients with GC.

1996-08-01

As a part of the Agreement on Environmental Cooperation between Norway and Slovakia a project ``Mapping Critical Levels/Loads for Slovakia`` was established. This report presents the final project results. Critical loads for forest, surface and ground waters and their exceedances were calculated by means of the steady-state mass balance model PROFILE for soils, and the steady-state water chemistry method for waters. A grid distance of 10 km was used. Because the sulphur deposition has been decreasing, the exceedances of critical load of acidity and critical sulphur deposition of forest soils have decreased from 1990 to 1995. Practically no acidity exceedances for surface water or ground water were found in 1995. The critical level of forest ozone was exceeded all over Slovakia. In the Tatra mountains the exceedance was over 25000 ppb.h. 23 refs., 3 figs., 3 tabs.

Microelementosis (imbalance of certain microelements in the body, ME is considered as one of the most important clinical and pathogenetic components of degenerative and inflammatory joint diseases. ME can play the role of co-factors involved in the processes of articular inflammation. Objective. To study the levels in the hair and to assess the clinical and pathogenetic significance of osteoassociated ME (cobalt — Co, copper — Cu, iron — Fe, lithium — Li, manganese — Mn, lead — Pb, strontium — Sr, zinc — Zn at a variety of arthritis — rheumatoid (RA, chlamydia-induced (ReA, psoriatic (PsA, gouty (PA and osteoarthritis (OA. Material and methods. There were 262 patients under observation, among them 89 persons suffered from RA, 31 — ReA, 35 — PsA, 49 — GA and 58 — OA. The distribution of males and females in these groups was 1 : 2, 2 : 1, 1 : 1, 11 : 1, 1 : 3, respectively, the average age of the patients was 47, 34, 42, 48 and 58 years old, while the duration of clinical manifestations of disease was 10, 4, 11, 7 and 12 years. ME in the hair was examined by atomic absorption spectrometer with electrographite atomizer «SolAAr-Mk2-MOZe». Results. All patients with arthritis are prone to have microelementosis in hair. All nosological forms of joint pathology are associated with a significant decrease of Mn level in hair, when the level of Pb and Fe accumulated. Only RA was characterized by the absence of changes in the hair level of Co, PsA — of Cu, PA — Li and Sr. If, in comparison with healthy persons, the PA proceeds with an increased concentration level of Zn in the hair, the OA is characterized by an increased level of ME, that has a certain differential diagnostic value. There is either direct relationship between the hair and blood serum indexes (Mn, Pb or multi-directional (Fe ones. Microelement blood composition depends on the activity level, clinical and laboratory signs of disease, the

The personnel dosimetry department of Greek Atomic Energy Commission (GAEC) is the only laboratory in the country that assures the individual monitoring of more than 10,500 workers with whole body dosemeters and 100 workers with extremity dosemeters at 1300 establishments. Every year a statistical analysis of the results is performed that provides data for epidemiological studies and assists the evaluation of the radiation protection system of the country. The aim of this study is to perform an analysis of the doses that are lower than the reporting level. The vast majority (92%) of the evaluated H p (10) doses has been reported and recorded as zero. The mean H p (10) (of the non-reported doses) per dosemeter and per monitoring period has been calculated for every geographical department of Greece. The results were compared with the ones produced by the external gamma rate measurements performed by GAEC's telemetric network. The conclusion that can be drawn is that the part of the TL signal of the personal dosemeters is due to the natural background radiation and this can affect the evaluation of the low doses

Objective: To explore the changes of serum IL-6, IL-8, IL-10 and IL-18 levels after treatment in patients with chronic renal diseases. Methods: Serum IL-6, IL-8, IL-10 levels were determined with RIA and IL-18 levels with ELISA in 32 patients with chronic renal diseases both before and after treatment as well as in 35 controls. Results: Before treatment the serum IL -6, IL-8, IL-10 and IL-18 levels were significantly higher in the patients than those in controls (P<0.01). After 6 months of treatment, the levels though dropped markedly remained significantly higher (P<0.05). Conclusion: Levels of serum IL-6, IL- 8, IL-10 and IL-18 increased significantly in patients with chronic renal diseases, especially in those advanced cases. (authors)

Objective: To investigate the changes of serum leptin, insulin levels and blood sugar contents in pregnant women with gestational glucose metabolism disturbances. Methods: Fasting and 3h after oral 50g glucose serum levels of leptin were measured with RIA in 36 pregnant women with glucose metabolism disturbances (gestational diabetes mellitus or gestational impaired glucose tolerance) and 34 controls. Also, fasting serum insulin levels (with CLIA) and blood sugar contents 1h after oral 50 glucose (with glucose oxidase method) were determined in all these subjects. Results: 1. Serum levels of leptin in pregnant women with glucose metabolism disturbances were 14.9 ± 4.3 μg/L (vs controls 9.8 ± 1.7 μg/L, P<0.01). 2. The serum levels of insulin and 1 h post - 50g glucose blood sugar contents in pregnant women with glucose metabolism disturbances were 12.9±4.3mU/L and 11.0±1.4mmol/L respectively, which were both significantly positively correlated with the serum leptin levels (r=0.835, r=0.758 respectively) (vs levels in controls: 8.45±3.0mU/L and 7.84±1.3mmol/L). Conclusion: Elevation of fasting serum levels of leptin was demonstrated in pregnant women with glucose metabolism disturbances and the level of leptin was positively correlated with that of insulin and blood sugar.

The goal of the current study was to examine the relationships between insight and both cognitive function and depression in schizophrenia and schizoaffective disorder, and to determine if there were similar relationships across diagnostic categories. We examined discrepancies between self and informant reports of function on the Specific levels of function scale as a metric of insight for interpersonal, social acceptance, work and activities. We examined two samples of individuals with schizophrenia and/or schizoaffective disorder (Ns of 188 and 67 respectively). In Sample 1, cognition was measured using the Dot Probe Expectancy Task. In Sample 2, cognition was measured by averaging several subtests from the MATRICS consensus cognitive battery, as well as additional measures of working memory. In both samples, depression was measured using the Brief Psychiatric Rating Scale. In both samples, we found significant relationships between worse cognition and overestimations of work function, as well as between higher depression levels and underestimation of interpersonal function. These relationships were specific to interpersonal and work function, with significantly stronger correlations with interpersonal and work function compared to the other areas of function. Similar results were found across diagnostic categories. These results have important implications for treatment planning, as they suggest the need to take into account depression and cognitive function when evaluating the patient's self-report of function, and highlight the utility of informant reports in evaluating function and treatment planning. Further, they add to the literature on the similarity across schizophrenia and schizoaffective disorder in a variety of pathological mechanisms.

Full Text Available Sensitivity to noise, particularly road traffic noise, can increase cortisol levels and result in changes in immune system biomarkers. Therefore, continuous exposure to noise can have an effect on immune function, hormonal levels, and cardiovascular function, leading to hypertension and stress. The purpose of this study was to investigate the changes in stress-and immune system-related biomarkers according to the self-reported sensitivity to noise and exposure to road traffic noise, to ultimately determine the potential effects of noise on health. A survey was conducted through questionnaire (ISO/TS 15666 sent to 172 female subjects in Korea, including 128 from Ulsan and 44 from Seoul. The average noise level was calculated, and blood samples were collected for measurements of cortisol levels, Natural killer (NK / Natural killer T (NKT cell populations, and NK cell activity (through measurements of interleukin-12 (IL-12 and interferon-gamma (INF-γ concentrations. Multivariate linear regression analysis of the measured biomarkers according to the road traffic noise level and self-reported noise sensitivity was conducted adjusting for the effects of age, alcohol status, smoking status, regular exercise, and residence period. IL-12 levels increased, whereas the NKT cell population decreased with increasing noise levels. The results further suggested that cortisol levels are more influenced by the subject's sensitivity to noise than to the level of chronic road traffic noise. Therefore, noise appears to have the largest effect on IL-12 levels as well as the population and activity of NKT cells. In conclusion, our results suggest that low-level road traffic noise and sensitivity to noise can affect health by causing changes in the immune response through mechanisms other than increased cortisol.
